                growth of capital, current income and a combination of growth
                and income. Each Portfolio of Janus Aspen Series currently

                (the "Shares") are sold under the name of "Janus Aspen Series"
                and are offered by this prospectus in connection with investment
                in and payments under variable annuity contracts and variable
                life insurance contracts (collectively, "variable insurance
                contracts"), as well as certain qualified retirement plans.

                be available in connection with a particular contract and
                certain contracts may limit allocations among the Portfolios.

                regarding contract fees and expenses and any restrictions on
                purchases or allocations.

                purchaser of a variable insurance contract or plan participant
                should consider in conjunction with the accompanying separate
                account prospectus of the specific insurance company product
                before allocating purchase payments or premiums to the
                Portfolios.

EQUITY PORTFOLIOS

          The Equity Portfolios are designed for long-term investors who seek
          growth of capital and who can tolerate the greater risks associated
          with common stock investments.

1. WHAT ARE THE INVESTMENT OBJECTIVES OF THE EQUITY PORTFOLIOS?

- --------------------------------------------------------------------------------

          DOMESTIC EQUITY PORTFOLIOS

          - GROWTH PORTFOLIO seeks long-term growth of capital in a manner
            consistent with the preservation of capital.

          - AGGRESSIVE GROWTH PORTFOLIO AND CAPITAL APPRECIATION PORTFOLIO
            seek long-term growth of capital.

          - BALANCED PORTFOLIO seeks long-term capital growth, consistent
            with preservation of capital and balanced by current income.

          - EQUITY INCOME PORTFOLIO seeks current income and long-term growth
            of capital.

          - GROWTH AND INCOME PORTFOLIO seeks long-term capital growth and
            current income.

          GLOBAL/INTERNATIONAL EQUITY PORTFOLIOS

          - INTERNATIONAL GROWTH PORTFOLIO, GLOBAL LIFE SCIENCES PORTFOLIO
            AND GLOBAL TECHNOLOGY PORTFOLIO seek long-term growth of capital.

          - WORLDWIDE GROWTH PORTFOLIO seeks long-term growth of capital in a
            manner consistent with the preservation of capital.

          The Portfolios' Trustees may change these objectives without a
          shareholder vote and the Portfolios will notify you of any changes
          that are material. If there is a material change to a Portfolio's
          objective or policies, you should consider whether that Portfolio
          remains an appropriate investment for you. There is no guarantee
          that a Portfolio will meet its objective.

2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF THE EQUITY PORTFOLIOS?

          The portfolio managers apply a "bottom up" approach in choosing
          investments. In other words, they look for companies with earnings
          growth potential one at a time. If a portfolio manager is unable to
          find investments with earnings growth potential, a significant portion
          of a Portfolio's assets may be in cash or similar investments.

          GROWTH PORTFOLIO invests primarily in common stocks selected for their
          growth potential. Although the Portfolio can invest in companies of
          any size, it generally invests in larger, more established companies.

          AGGRESSIVE GROWTH PORTFOLIO invests primarily in common stocks
          selected for their growth potential, and normally invests at least 50%
          of its equity assets in medium-sized companies.

          CAPITAL APPRECIATION PORTFOLIO invests primarily in common stocks
          selected for their growth potential. The Portfolio may invest in
          companies of any size, from larger, well-established companies to
          smaller, emerging growth companies.

 2 Janus Aspen Series
<PAGE>

          BALANCED PORTFOLIO normally invests 40-60% of its assets in securities
          selected primarily for their growth potential and 40-60% of its assets
          in securities selected primarily for their income potential. The
          Portfolio will normally invest at least 25% of its assets in
          fixed-income securities.

          EQUITY INCOME PORTFOLIO normally emphasizes investments in common
          stocks, and growth potential is a significant investment
          consideration. Normally, it invests at least 65% of its assets in
          income-producing equity securities.

          GROWTH AND INCOME PORTFOLIO normally emphasizes investments in common
          stocks. It will normally invest up to 75% of its assets in equity
          securities selected primarily for their growth potential, and at least
          25% of its assets in securities the portfolio manager believes have
          income potential. Equity securities may make up part of this income
          component if they currently pay dividends or the portfolio manager
          believes they have potential for increasing or commencing dividend
          payments.

          INTERNATIONAL GROWTH PORTFOLIO normally invests at least 65% of its
          total assets in securities of issuers from at least five different
          countries, excluding the United States. Although the Portfolio intends
          to invest substantially all of its assets in issuers located outside
          the United States, it may invest in U.S. issuers and it may at times
          invest all of its assets in fewer than five countries, or even a
          single country.

          WORLDWIDE GROWTH PORTFOLIO invests primarily in common stocks of
          companies of any size throughout the world. The Portfolio normally
          invests in issuers from at least five different countries, including
          the United States. The Portfolio may at times invest in fewer than
          five countries or even a single country.


          GLOBAL LIFE SCIENCES PORTFOLIO invests primarily in equity securities
          of U.S. and foreign companies selected for their growth potential.
          Normally, it invests at least 65% of its total assets in securities of
          companies that the portfolio manager believes have a life science
          orientation. Generally speaking, the "life sciences" relate to
          maintaining or improving quality of life. So, for example, companies
          with a "life science orientation" include companies engaged in
          research development, production or distribution of products or
          services related to health and personal care, medicine or
          pharmaceuticals. As a fundamental policy, the Portfolio normally
          invests at least 25% of its total assets, in the aggregate, in the
          following industry groups: healthcare; pharmaceuticals; agriculture;
          cosmetics/personal care; and biotechnology.



          GLOBAL TECHNOLOGY PORTFOLIO invests primarily in equity securities of
          U.S. and foreign companies selected for their growth potential. Under
          normal circumstances, it invests at least 65% of its total assets in
          securities of companies that the portfolio manager believes will
          benefit significantly from advances or improvements in technology.



3. WHAT ARE THE MAIN RISKS OF INVESTING IN THE EQUITY PORTFOLIOS?



          The biggest risk of investing in these Portfolios is that their
          returns may vary, and you could lose money. If you are considering
          investing in any of the Equity Portfolios, remember that they are each
          designed for long-term investors who can accept the risks of investing
          in a portfolio with significant common stock holdings. Common stocks
          tend to be more volatile than other investment choices.



          The value of a Portfolio's holdings may decrease if the value of an
          individual company in the portfolio decreases. The value of a
          Portfolio's holdings could also decrease if the stock market goes
          down. If the value of a Portfolio's holdings decreases, that
          Portfolio's net asset value (NAV) will also decrease, which means if
          you sell your shares in a Portfolio you would get back less money.


          The income component of BALANCED PORTFOLIO, EQUITY INCOME PORTFOLIO
          AND GROWTH AND INCOME PORTFOLIO includes fixed-income securities. A
          fundamental risk to the income component is that the value of these
          securities will fall if interest rates rise. Generally, the value of a
          fixed-income portfolio will

                                                          Risk return summary  3
<PAGE>

          decrease when interest rates rise, which means the Portfolio's NAV may
          likewise decrease. Another fundamental risk associated with
          fixed-income securities is credit risk, which is the risk that an
          issuer of a bond will be unable to make principal and interest
          payments when due.


          GLOBAL LIFE SCIENCES PORTFOLIO concentrates its investments in related
          industry groups. Because of this, companies in its portfolio may share
          common characteristics and react similarly to market developments. For
          example, many companies with a life science orientation are highly
          regulated and may be dependent upon certain types of technology. As a
          result, changes in government funding or subsidies, new or anticipated
          legislative changes, or technological advances could affect the value
          of such companies and, therefore, the Portfolio's NAV. The Portfolio's
          returns may be more volatile than those of a less concentrated
          portfolio.



          Although GLOBAL TECHNOLOGY PORTFOLIO does not concentrate its
          investments in specific industries, it may invest in companies related
          in such a way that they react similarly to certain market pressures.
          For example, competition among technology companies may result in
          increasingly aggressive pricing of their products and services, which
          may affect the profitability of companies in the portfolio. In
          addition, because of the rapid pace of technological development,
          products or services developed by companies in the Portfolio's
          portfolio may become rapidly obsolete or have relatively short product
          cycles. As a result, the Portfolio's returns may be considerably more
          volatile than the returns of a fund that does not invest in similarly
          related companies.



          INTERNATIONAL GROWTH PORTFOLIO, WORLDWIDE GROWTH PORTFOLIO, GLOBAL
          LIFE SCIENCES PORTFOLIO AND GLOBAL TECHNOLOGY PORTFOLIO may have
          significant exposure to foreign markets. As a result, their returns
          and NAV may be affected to a large degree by fluctuations in currency
          exchange rates or political or economic conditions in a particular
          country.



          AGGRESSIVE GROWTH PORTFOLIO, CAPITAL APPRECIATION PORTFOLIO, GLOBAL
          LIFE SCIENCES PORTFOLIO AND GLOBAL TECHNOLOGY PORTFOLIO are
          nondiversified. In other words, they may hold larger positions in a
          smaller number of securities than a diversified fund. As a result, a
          single security's increase or decrease in value may have a greater
          impact on a Portfolio's NAV and total return.


          An investment in these Portfolios is not a bank deposit and is not
          insured or guaranteed by the Federal Deposit Insurance Corporation or
          any other government agency.


          The following information provides some indication of the risks of
          investing in the Equity Portfolios by showing how each of the Equity
          Portfolios' performance has varied over time. The bar charts depict
          the change in performance from year-to-year during the period
          indicated, but do not include charges and expenses attributable to any
          insurance product which would lower the performance illustrated. The
          Portfolios do not impose any sales or other charges that would affect
          total return computations. Total return figures include the effect of
          each Portfolio's expenses. The tables compare the average annual
          returns for the Shares of each Portfolio for the periods indicated to
          a broad-based securities market index.

FIXED-INCOME PORTFOLIOS

          The Fixed-Income Portfolios are designed for long-term investors who
          primarily seek current income.

1. WHAT ARE THE INVESTMENT OBJECTIVES OF THE FIXED-INCOME PORTFOLIOS?

- --------------------------------------------------------------------------------

          - FLEXIBLE INCOME PORTFOLIO seeks to obtain maximum total return,
            consistent with preservation of capital.

          - HIGH-YIELD PORTFOLIO seeks to obtain high current income. Capital
            appreciation is a secondary objective when consistent with its
            primary objective.

          The Trustees may change these objectives without a shareholder vote
          and the Portfolios will notify you of any changes that are material.
          If there is a material change to a Portfolio's objective or policies,
          you should consider whether it remains an appropriate investment for
          you. There is no guarantee that a Portfolio will meet its objective.

2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF THE FIXED-INCOME PORTFOLIOS?

          In addition to considering economic factors such as the effect of
          interest rates on a Portfolio's investments, the portfolio managers
          apply a "bottom up" approach in choosing investments. In other words,
          they look mostly for income-producing securities that meet their
          investment criteria one at a time. If a portfolio manager is unable to
          find such investments, a Portfolio's assets may be in cash or similar
          investments.


          FLEXIBLE INCOME PORTFOLIO invests primarily in a wide variety of
          income-producing securities such as corporate bonds and notes,
          government securities and preferred stock. As a fundamental policy,
          the Portfolio will invest at least 80% of its assets in
          income-producing securities. The Portfolio may own an unlimited amount
          of high-yield/high-risk bonds, and these securities may be a big part
          of the portfolio.


          HIGH-YIELD PORTFOLIO normally invests at least 65% of its assets in
          high-yield/high-risk fixed-income securities, and may at times invest
          all of its assets in these securities.

3. WHAT ARE THE MAIN RISKS OF INVESTING IN THE FIXED-INCOME PORTFOLIOS?

          Although the Fixed-Income Portfolios may be less volatile than funds
          that invest most of their assets in common stocks, the Portfolios'
          returns and yields will vary, and you could lose money.

          The Portfolios invest in a variety of fixed-income securities. A
          fundamental risk is that the value of these securities will fall if
          interest rates rise. Generally, the value of a fixed-income portfolio
          will decrease when interest rates rise, which means the Portfolio's
          NAV will likewise decrease. Another fundamental risk associated with
          fixed-income funds is credit risk, which is the risk that an issuer
          will be unable to make principal and interest payments when due.


          FLEXIBLE INCOME PORTFOLIO AND HIGH-YIELD PORTFOLIO may invest an
          unlimited amount of their assets in high-yield/high-risk bonds, also
          known as "junk" bonds which may be sensitive to economic changes,
          political changes, or adverse developments specific to the company
          that issued the bond. These bonds generally have a greater credit risk
          than other types of fixed-income securities. Because of these factors,
          the performance and NAV of the Fixed-Income Portfolios may vary
          significantly, depending upon their holdings of junk bonds.


          An investment in these Portfolios is not a bank deposit and is not
          insured or guaranteed by the Federal Deposit Insurance Corporation or
          any other government agency.

          The following information provides some indication of the risks of
          investing in the Fixed-Income Portfolios by showing how each
          Fixed-Income Portfolio's performance has varied over time. The bar
          charts depict the change in performance from year-to-year during the
          period indicated, but do not include charges and expenses attributable
          to any insurance product which would lower the performance
          illustrated. The Portfolios do not impose any sales or other charges
          that would affect total return computations. Total return figures
          include the effect of each Portfolio's expenses. The tables compare
          the average annual returns for the Shares of each Portfolio for the
          periods indicated to a broad-based securities market index.

MONEY MARKET PORTFOLIO

          Money Market Portfolio is designed for investors who seek current
          income.

1. WHAT IS THE INVESTMENT OBJECTIVE OF MONEY MARKET PORTFOLIO?

- --------------------------------------------------------------------------------

          - MONEY MARKET PORTFOLIO seeks maximum current income to the extent
            consistent with stability of capital.

          The Trustees may change this objective without a shareholder vote and
          the Portfolio will notify you of any changes that are material. If
          there is a material change in the Portfolio's objective or policies,
          you should consider whether it remains an appropriate investment for
          you. There is no guarantee that the Portfolio will meet its objective.

2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF MONEY MARKET PORTFOLIO?

          MONEY MARKET PORTFOLIO will invest only in high-quality, short-term
          money market instruments that present minimal credit risks, as
          determined by Janus Capital. The Portfolio invests primarily in high
          quality debt obligations and obligations of financial institutions.
          Debt obligations may include commercial paper, notes and bonds, and
          variable amount master demand notes. Obligations of financial
          institutions include certificates of deposit and time deposits.

3. WHAT ARE THE MAIN RISKS OF INVESTING IN MONEY MARKET PORTFOLIO?

          The Portfolio's yields will vary as the short-term securities in the
          portfolio mature and the proceeds are reinvested in securities with
          different interest rates. Over time, the real value of the Portfolio's
          yield may be eroded by inflation. Although Money Market Portfolio
          invests only in high-quality, short-term money market instruments,
          there is a risk that the value of the securities it holds will fall as
          a result of changes in interest rates, an issuer's actual or perceived
          credit-worthiness or an issuer's ability to meet its obligations.

          An investment in Money Market Portfolio is not a deposit of a bank and
          is not insured or guaranteed by the Federal Deposit Insurance
          Corporation or any other government agency. Although the Portfolio
          seeks to preserve the value of your investment at $1.00 per share, it
          is possible to lose money by investing in Money Market Portfolio.

          The following information provides some indication of the risks of
          investing in the Money Market Portfolio by showing how Money Market
          Portfolio's performance has varied over time. The bar chart depicts
          the change in performance from year to year, but does not include
          charges and expenses attributable to any insurance product which would
          lower the performance illustrated. The Portfolio does not impose any
          sales or other charges that would affect total return or yield
          computations. Total return and yield figures include the effect of the
          Portfolio's expenses.

FEES AND EXPENSES

          SHAREHOLDER FEES, such as sales loads, redemption fees or exchange
          fees, are charged directly to an investor's account. All Janus funds
          are no-load investments, so you will not pay any shareholder fees when
          you buy or sell shares of the Portfolios. However, each variable
          insurance contract involves fees and expenses not described in this
          prospectus. See the accompanying contract prospectus for information
          regarding contract fees and expenses and any restrictions on purchases
          or allocations.

          ANNUAL FUND OPERATING EXPENSES are paid out of a Portfolio's assets
          and include fees for portfolio management, maintenance of shareholder
          accounts, shareholder servicing, accounting and other services. You do
          not pay these fees directly but, as the example on the next page
          shows, these costs are borne indirectly by all shareholders.

     Growth, Aggressive Growth, Capital Appreciation, International Growth,
     Worldwide Growth, Balanced, Equity Income and Growth and Income
     Portfolios. Expenses for Global Technology and Global Life Sciences
     Portfolios are based on the estimated expenses that those Portfolios
     expect to incur in their initial fiscal year. Expenses are stated both
     with and without contractual waivers by Janus Capital. Waivers, if
     applicable, are first applied against the management fee and then
     against other expenses, and will continue until at least the next annual
     renewal of the advisory agreement. All expenses are shown without the
     effect of any expense offset arrangements.

   EXAMPLE:

   THE FOLLOWING EXAMPLE IS BASED ON EXPENSES WITHOUT WAIVERS (IF ANY).
   This example is intended to help you compare the cost of investing in
   the Portfolios with the cost of investing in other mutual funds. The
   example assumes that you invest $10,000 in each of the Portfolios for
   the time periods indicated then redeem all of your shares at the end of
   those periods. The example also assumes that your investment has a 5%
   return each year, and that the Portfolios' operating expenses remain the
   same. Although your actual costs may be higher or lower, based on these
   assumptions your costs would be:

EQUITY PORTFOLIOS



          This section takes a closer look at the investment objectives of each
          of the Equity Portfolios, their principal investment strategies and
          certain risks of investing in the Equity Portfolios. Strategies and
          policies that are noted as "fundamental" cannot be changed without a
          shareholder vote.



          Please carefully review the "Risks" section of this Prospectus on
          pages 25-28 for a discussion of risks associated with certain
          investment techniques. We've also included a Glossary with
          descriptions of investment terms used throughout this Prospectus.


INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES


DOMESTIC EQUITY PORTFOLIOS


          GROWTH PORTFOLIO
          Growth Portfolio seeks long-term growth of capital in a manner
          consistent with the preservation of capital. It pursues its objective
          by investing primarily in common stocks selected for their growth
          potential. Although the Portfolio can invest in companies of any size,
          it generally invests in larger, more established companies.

          AGGRESSIVE GROWTH PORTFOLIO
          Aggressive Growth Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in common stocks selected
          for their growth potential, and normally invests at least 50% of its

 16 Janus Aspen Series
<PAGE>


          equity assets in medium-sized companies. Medium-sized companies are
          those whose market capitalization falls within the range of companies
          in the S&P MidCap 400 Index. Market capitalization is a commonly used
          measure of the size and value of a company. The market capitalizations
          within the Index will vary, but as of December 31, 1999, they ranged
          from approximately $170 million to $37 billion.


          CAPITAL APPRECIATION PORTFOLIO
          Capital Appreciation Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in common stocks selected
          for their growth potential. The Portfolio may invest in companies of
          any size, from larger, well-established companies to smaller, emerging
          growth companies.

          BALANCED PORTFOLIO
          Balanced Portfolio seeks long-term capital growth, consistent with
          preservation of capital and balanced by current income. It pursues its
          objective by normally investing 40-60% of its assets in securities
          selected primarily for their growth potential and 40-60% of its assets
          in securities selected primarily for their income potential. This
          Portfolio normally invests at least 25% of its assets in fixed-income
          securities.

          EQUITY INCOME PORTFOLIO
          Equity Income Portfolio seeks current income and long-term growth of
          capital. It pursues its objective by normally emphasizing investments
          in common stock, and growth potential is a significant investment
          consideration. The Portfolio tries to provide a lower level of
          volatility than the S&P 500 Index. Normally, it invests at least 65%
          of its assets in income-producing equity securities including common
          and preferred stocks, warrants and securities that are convertible to
          common or preferred stocks.

          GROWTH AND INCOME PORTFOLIO
          Growth and Income Portfolio seeks long-term capital growth and current
          income. It normally emphasizes investments in common stocks. It will
          normally invest up to 75% of its assets in equity securities selected
          primarily for their growth potential, and at least 25% of its assets
          in securities the portfolio manager believes have income potential.
          Because of this investment strategy, the Portfolio is not designed for
          investors who need consistent income.


GLOBAL/INTERNATIONAL EQUITY PORTFOLIOS


          INTERNATIONAL GROWTH PORTFOLIO
          International Growth Portfolio seeks long-term growth of capital.
          Normally, the Portfolio pursues its objective by investing at least
          65% of its total assets in securities of issuers from at least five
          different countries, excluding the United States. Although the
          Portfolio intends to invest substantially all of its assets in issuers
          located outside the United States, it may at times invest in U.S.
          issuers and it may at times invest all of its assets in fewer than
          five countries or even a single country.

          WORLDWIDE GROWTH PORTFOLIO
          Worldwide Growth Portfolio seeks long-term growth of capital in a
          manner consistent with the preservation of capital. It pursues its
          objective by investing primarily in common stocks of companies of any
          size throughout the world. The Portfolio normally invests in issuers
          from at least five different countries, including the United States.
          The Portfolio may at times invest in fewer than five countries or even
          a single country.

          GLOBAL LIFE SCIENCES PORTFOLIO


          Global Life Sciences Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in equity securities of
          U.S. and foreign companies selected for their growth potential.
          Normally, it invests at least 65% of its total assets in securities of
          companies that the portfolio manager believes have a life science
          orientation. As a fundamental policy, the Portfolio normally invests
          at least 25% of its total assets, in the aggregate, in the following
          industry groups: health care; pharmaceuticals; agriculture;
          cosmetics/personal care; and biotechnology.



          GLOBAL TECHNOLOGY PORTFOLIO


          Global Technology Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in equity securities of
          U.S. and foreign companies selected for their growth potential.
          Normally, it invests at least 65% of its total assets in securities of
          companies that the portfolio manager believes will benefit
          significantly from advances or improvements in technology. These
          companies generally fall into two categories:



          a. Companies that the portfolio manager believes have or will develop
             products, processes or services that will provide significant
             technological advancements or improvements; and



          b. Companies that the portfolio manager believes rely extensively on
             technology in connection with their operations or services.



The following questions and answers are designed to help you better understand
the Equity Portfolios' principal investment strategies.


1. HOW ARE COMMON STOCKS SELECTED?


          Each of the Portfolios may invest substantially all of its assets in
          common stocks if its portfolio manager believes that common stocks
          will appreciate in value. The portfolio managers generally take a
          "bottom up" approach to selecting companies. In other words, they seek
          to identify individual companies with earnings growth potential that
          may not be recognized by the market at large. They make this
          assessment by looking at companies one at a time, regardless of size,
          country of organization, place of principal business activity, or
          other similar selection criteria. Except for Balanced Portfolio,
          Equity Income Portfolio and Growth and Income Portfolio, realization
          of income is not a significant consideration when choosing investments
          for the Portfolios. Income realized on the Portfolios' investments may
          be incidental to their objectives. In the case of Balanced Portfolio,
          Equity Income Portfolio and Growth and Income Portfolio, a portfolio
          manager may consider dividend-paying characteristics to a greater
          degree in selecting common stock.


2. ARE THE SAME CRITERIA USED TO SELECT FOREIGN SECURITIES?

          Generally, yes. The portfolio managers seek companies that meet their
          selection criteria, regardless of where a company is located. Foreign
          securities are generally selected on a stock-by-stock basis without
          regard to any defined allocation among countries or geographic
          regions. However, certain factors such as expected levels of
          inflation, government policies influencing business conditions, the
          outlook for currency relationships, and prospects for economic growth
          among countries, regions or geographic areas may warrant greater
          consideration in selecting foreign securities. There are no
          limitations on the countries in which the Portfolios may invest and
          the Portfolios may at times have significant foreign exposure.

3. WHAT DOES "MARKET CAPITALIZATION" MEAN?



          Market capitalization is the most commonly used measure of the size
          and value of a company. It is computed by multiplying the current
          market price of a share of the company's stock by the total number of
          its shares outstanding. As noted previously, market capitalization is
          an important investment criteria for Aggressive Growth Portfolio.
          Although the other Equity Portfolios offered by this Prospectus do not
          emphasize companies of any particular size, Portfolios with a larger
          asset base are more likely to invest in larger, more established
          issuers.



4. HOW DO BALANCED PORTFOLIO, EQUITY INCOME PORTFOLIO AND GROWTH AND INCOME
   PORTFOLIO DIFFER FROM EACH OTHER?



          Growth and Income Portfolio places a greater emphasis on aggressive
          growth stocks and may derive a greater portion of its income from
          dividend-paying common stocks. Because of these factors, its NAV can
          be expected to fluctuate more than Balanced Portfolio or Equity Income
          Portfolio. Although Equity Income Portfolio invests substantially all
          of its assets in common stocks, it emphasizes investments in dividend-
          paying common stocks and other equity securities characterized by
          relatively greater price stability, and thus may be expected to be
          less volatile than Growth and Income Portfolio, as discussed in more
          detail below. Balanced Portfolio places a greater emphasis on the
          income component of its portfolio and invests to a greater degree in
          securities selected primarily for their income potential. As a result
          it is expected to be less volatile than Equity Income Portfolio and
          Growth and Income Portfolio.



5. HOW DOES EQUITY INCOME PORTFOLIO TRY TO LIMIT PORTFOLIO VOLATILITY?


          Equity Income Portfolio seeks to provide a lower level of volatility
          than the stock market at large, as measured by the S&P 500. The lower
          volatility sought by this Portfolio is expected to result primarily
          from investments in dividend-paying common stocks and other equity
          securities characterized by relatively greater price stability. The
          greater price stability sought by Equity Income Portfolio may be
          characteristic of companies that generate above average free cash
          flows. A company may use free cash flows for a number of purposes
          including commencing or increasing dividend payments, repurchasing its
          own stock or retiring outstanding debt. The portfolio manager also
          considers growth potential in selecting this Portfolio's securities
          and may hold securities selected solely for their growth potential.


6. HOW ARE ASSETS ALLOCATED BETWEEN THE GROWTH AND INCOME COMPONENTS OF BALANCED
   PORTFOLIO'S AND GROWTH AND INCOME PORTFOLIO'S HOLDINGS?


          Balanced Portfolio and Growth and Income Portfolio shift assets
          between the growth and income components of their holdings based on
          the portfolio managers' analysis of relevant market, financial and
          economic conditions. If a portfolio manager believes that growth
          securities will provide better returns than the yields then available
          or expected on income-producing securities, that Portfolio will place
          a greater emphasis on the growth component.


7. WHAT TYPES OF SECURITIES MAKE UP THE GROWTH COMPONENT OF THE BALANCED
   PORTFOLIO, EQUITY INCOME PORTFOLIO AND GROWTH AND INCOME PORTFOLIO?



          The growth component of these portfolios is expected to consist
          primarily of common stocks, but may also include warrants, preferred
          stocks or convertible securities selected primarily for their growth
          potential.



8. WHAT TYPES OF SECURITIES MAKE UP THE INCOME COMPONENT OF BALANCED PORTFOLIO'S
   AND GROWTH AND INCOME PORTFOLIO'S HOLDINGS?



          The income component of Balanced Portfolio and Growth and Income
          Portfolio is expected to consist of securities that the portfolio
          managers believe have income potential. Such securities may include
          equity


            Investment objectives, principal investment strategies and risks  19
<PAGE>

          securities, convertible securities and all types of debt securities.
          Equity securities may be included in the income component of a
          Portfolio if they currently pay dividends or the portfolio manager
          believes they have the potential for either increasing their dividends
          or commencing dividends, if none are currently paid.


9. WHAT DOES "LIFE SCIENCE ORIENTATION" MEAN IN RELATION TO GLOBAL LIFE SCIENCES
   PORTFOLIO?



          Generally speaking, the "life sciences" relate to maintaining or
          improving quality of life. So, for example, companies with a "life
          science orientation" include companies engaged in research,
          development, production or distribution of products or services
          related to health and personal care, medicine or pharmaceuticals. Life
          science oriented companies also include companies that the portfolio
          manager believes have growth potential primarily as a result of
          particular products, technology, patents or other market advantages in
          the life sciences. Life sciences encompass a variety of industries,
          including health care, nutrition, agriculture, medical diagnostics,
          nuclear and biochemical research and development and health care
          facilities ownership and operation.



10. HOW DOES GLOBAL TECHNOLOGY PORTFOLIO'S INDUSTRY POLICY DIFFER FROM THAT OF
    GLOBAL LIFE SCIENCES PORTFOLIO?



          Unlike Global Life Sciences Portfolio, Global Technology Portfolio
          will not concentrate its investments in any particular industry or
          group of related industries. As a result, its portfolio manager may
          have more flexibility to find companies that he believes will benefit
          from advances or improvements in technology in a number of industries.
          Nevertheless, the Portfolio may hold a significant portion of its
          assets in industries such as: aerospace/defense; biotechnology;
          computers; office/business equipment; semi-conductors; software;
          telecommunications; and telecommunications equipment.

FIXED-INCOME PORTFOLIOS

          This section takes a closer look at the investment objectives of each
          of the Fixed-Income Portfolios, their principal investment strategies
          and certain risks of investing in the Fixed-Income Portfolios.
          Strategies and policies that are noted as "fundamental" cannot be
          changed without a shareholder vote.


          Please carefully review the "Risks" section of this Prospectus on
          pages 25-28 for a discussion of risks associated with certain
          investment techniques. We've also included a Glossary with
          descriptions of investment terms used throughout this Prospectus.


INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES

          In addition to considering economic factors such as the effect of
          interest rates on a Portfolio's investments, the portfolio managers
          apply a "bottom up" approach in choosing investments. In other words,
          they look mostly for income-producing securities that meet their
          investment criteria one at a time. If a portfolio manager is unable to
          find such investments, much of a Portfolio's assets may be in cash or
          similar investments.

          FLEXIBLE INCOME PORTFOLIO

          Flexible Income Portfolio seeks to obtain maximum total return,
          consistent with preservation of capital. It pursues its objective by
          primarily investing in a wide variety of income-producing securities
          such as corporate bonds and notes, government securities and preferred
          stock. As a fundamental policy, the Portfolio will invest at least 80%
          of its assets in income-producing securities. The Portfolio may own an
          unlimited amount of high-yield/high-risk bonds, and these may be a big
          part of the portfolio. This Portfolio generates total return from a
          combination of current income and capital appreciation, but income is
          usually the dominant portion.


          HIGH-YIELD PORTFOLIO

          High-Yield Portfolio seeks to obtain high current income. Capital
          appreciation is a secondary objective when consistent with its primary
          objective. It pursues its objectives by normally investing 65% of its
          assets in high-yield/high-risk securities, and may at times invest all
          of its assets in these securities.


The following questions and answers are designed to help you better understand
the Fixed-Income Portfolios' principal investment strategies.

1. HOW DO INTEREST RATES AFFECT THE VALUE OF MY INVESTMENT?

          Generally, a fixed-income security will increase in value when
          interest rates fall and decrease in value when interest rates rise.
          Longer-term securities are generally more sensitive to interest rate
          changes than shorter-term securities, but they generally offer higher
          yields to compensate investors for the associated risks. High-yield
          bond prices are generally less directly responsive to interest rate
          changes than investment grade issues and may not always follow this
          pattern. A bond fund's average-weighted effective maturity and its
          duration are measures of how the fund may react to interest rate
          changes.

2. HOW DO THE FIXED-INCOME PORTFOLIOS MANAGE INTEREST RATE RISK?

          Each Fixed-Income Portfolio may vary the average-weighted effective
          maturity of its assets to reflect its portfolio manager's analysis of
          interest rate trends and other factors. A Portfolio's average-weighted
          effective maturity will tend to be shorter when the portfolio manager
          expects interest rates to rise and longer when its portfolio manager
          expects interest rates to fall. The Portfolios may also use futures,
          options and other derivatives to manage interest rate risks.

3. WHAT IS MEANT BY A PORTFOLIO'S "AVERAGE-WEIGHTED EFFECTIVE MATURITY"?

          The stated maturity of a bond is the date when the issuer must repay
          the bond's entire principal value to an investor. Some types of bonds
          may also have an "effective maturity" that is shorter than the stated
          date due to prepayment or call provisions. Securities without
          prepayment or call provisions generally have an effective maturity
          equal to their stated maturity. Dollar-weighted effective maturity is
          calculated by averaging the effective maturity of bonds held by a
          Portfolio with each effective maturity "weighted" according to the
          percentage of net assets that it represents.

4. WHAT IS MEANT BY A PORTFOLIO'S "DURATION"?

          A bond's duration indicates the time it will take an investor to
          recoup his investment. Unlike average maturity, duration reflects both
          principal and interest payments. Generally, the higher the coupon rate
          on a bond, the lower its duration will be. The duration of a bond
          portfolio is calculated by averaging the duration of bonds held by a
          fund with each duration "weighted" according to the percentage of net
          assets that it represents. Because duration accounts for interest
          payments, a Portfolio's duration is usually shorter than its average
          maturity.


5. WHAT IS A HIGH-YIELD/HIGH-RISK BOND?



          A high-yield/high-risk bond (also called a "junk" bond) is a bond
          rated below investment grade by major rating agencies (i.e., BB or
          lower by Standard & Poor's or Ba or lower by Moody's) or an unrated
          bond of similar quality. It presents greater risk of default (the
          failure to make timely interest and principal payments) than higher
          quality bonds.


GENERAL PORTFOLIO POLICIES OF THE PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO

          Unless otherwise stated, each of the following policies applies to all
          of the Portfolios other than Money Market Portfolio. The percentage
          limitations included in these policies and elsewhere in this
          Prospectus apply at the time of purchase of the security. So, for
          example, if a Portfolio exceeds a limit as a result of market
          fluctuations or the sale of other securities, it will not be required
          to dispose of any securities.

          CASH POSITION
          When a portfolio manager believes that market conditions are
          unfavorable for profitable investing, or when he or she is otherwise
          unable to locate attractive investment opportunities, the Portfolios'
          cash or similar investments may increase. In other words, the
          Portfolios do not always stay fully invested in stocks and bonds. Cash
          or similar investments generally are a residual - they represent the
          assets that remain after a portfolio manager has committed available
          assets to desirable investment opportunities. However, a portfolio
          manager may also temporarily increase a Portfolio's cash position to
          protect its assets or maintain liquidity. Partly because the portfolio
          managers act independently of each other, the cash positions of the
          Portfolios may vary significantly.

          When a Portfolio's investments in cash or similar investments
          increase, it may not participate in market advances or declines to the
          same extent that it would if the Portfolio remained more fully
          invested in stocks or bonds.

          OTHER TYPES OF INVESTMENTS

          The Equity Portfolios invest primarily in domestic and foreign equity
          securities, which may include preferred stocks, common stocks,
          warrants and securities convertible into common or preferred stocks.
          The Equity Portfolios also invest in domestic and foreign equity
          securities with varying degrees of emphasis on


 22 Janus Aspen Series
<PAGE>

          income. The Portfolios may also invest to a lesser degree in other
          types of securities. These securities (which are described in the
          Glossary) may include:

          - debt securities

          - indexed/structured securities


          - high-yield/high-risk bonds (less than 35% of each Portfolio's
            assets)



          - options, futures, forwards, swaps and other types of derivatives for
            hedging purposes or for non-hedging purposes such as seeking to
            enhance return


          - securities purchased on a when-issued, delayed delivery or forward
            commitment basis

          The Fixed-Income Portfolios invest primarily in fixed-income
          securities which may include corporate bonds and notes, government
          securities, preferred stock, high-yield/high-risk fixed-income
          securities and municipal obligations. The Portfolios may also invest
          to a lesser degree in other types of securities. These securities
          (which are described in the Glossary) may include:

          - common stocks

          - mortgage- and asset-backed securities

          - zero coupon, pay-in-kind and step coupon securities


          - options, futures, forwards, swaps and other types of derivatives for
            hedging purposes or for non-hedging purposes such as seeking to
            enhance return


          - securities purchased on a when-issued, delayed delivery or forward
            commitment basis

          ILLIQUID INVESTMENTS
          Each Portfolio may invest up to 15% of its net assets in illiquid
          investments. An illiquid investment is a security or other position
          that cannot be disposed of quickly in the normal course of business.
          For example, some securities are not registered under U.S. securities
          laws and cannot be sold to the U.S. public because of SEC regulations
          (these are known as "restricted securities"). Under procedures adopted
          by the Portfolios' Trustees, certain restricted securities may be
          deemed liquid, and will not be counted toward this 15% limit.

          FOREIGN SECURITIES
          The Portfolios may invest without limit in foreign equity and debt
          securities. The Portfolios may invest directly in foreign securities
          denominated in a foreign currency and not publicly traded in the
          United States. Other ways of investing in foreign securities include
          depositary receipts or shares, and passive foreign investment
          companies.

          SPECIAL SITUATIONS
          Each Portfolio may invest in special situations. A special situation
          arises when, in the opinion of a Portfolio's manager, the securities
          of a particular issuer will be recognized and appreciate in value due
          to a specific development with respect to that issuer. Developments
          creating a special situation might include, among others, a new
          product or process, a technological breakthrough, a management change
          or other extraordinary corporate event, or differences in market
          supply of and demand for the security. A Portfolio's performance could
          suffer if the anticipated development in a "special situation"
          investment does not occur or does not attract the expected attention.

          PORTFOLIO TURNOVER
          The Portfolios generally intend to purchase securities for long-term
          investment although, to a limited extent, a Portfolio may purchase
          securities in anticipation of relatively short-term price gains.
          Short-term transactions may also result from liquidity needs,
          securities having reached a price or yield objective, changes in
          interest rates or the credit standing of an issuer, or by reason of
          economic or other developments not foreseen at the time of the
          investment decision. A Portfolio may also sell one security and
          simultaneously purchase the same or a comparable security to take
          advantage of short-term differentials in bond yields or securities
          prices. Changes are made in a Portfolio's holdings whenever its
          portfolio manager believes such changes are desirable. Portfolio
          turnover rates are generally not a factor in making buy and sell
          decisions.


          Global Technology Portfolio may invest in companies with relatively
          short product cycles, for example, 6 to 9 months. Consequently its
          portfolio turnover may be more frequent. Increased portfolio turnover
          may result in higher costs for brokerage commissions, dealer mark-ups
          and other transaction costs and may also result in taxable capital
          gains. Higher costs associated with increased portfolio turnover may
          offset gains in a Portfolio's performance.

RISKS FOR EQUITY PORTFOLIOS



          Because the Portfolios may invest substantially all of their assets in
          common stocks, the main risk is the risk that the value of the stocks
          they hold might decrease in response to the activities of an
          individual company or in response to general market and/or economic
          conditions. If this occurs, a Portfolio's share price may also
          decrease. A Portfolio's performance may also be affected by risks
          specific to certain types of investments, such as foreign securities,
          derivative investments, non-investment grade debt securities, initial
          public offerings (IPOs) or companies with relatively small market
          capitalizations. IPOs and other investment techniques may have a
          magnified performance impact on a portfolio with a small asset base. A
          portfolio may not experience similar performance as its assets grow.
          Global Technology Portfolio's performance may also be affected by
          industry risk.



The following questions and answers are designed to help you better understand
some of the risks of investing in the Equity Portfolios.


1. THE PORTFOLIOS MAY INVEST IN SMALLER OR NEWER COMPANIES. DOES THIS CREATE ANY
   SPECIAL RISKS?


          Many attractive investment opportunities may be smaller, start-up
          companies offering emerging products or services. Smaller or newer
          companies may suffer more significant losses as well as realize more
          substantial growth than larger or more established issuers because
          they may lack depth of management, be unable to generate funds
          necessary for growth or potential development, or be developing or
          marketing new products or services for which markets are not yet
          established and may never become established. In addition, such
          companies may be insignificant factors in their industries and may
          become subject to intense competition from larger or more established
          companies. Securities of smaller or newer companies may have more
          limited trading markets than the markets for securities of larger or
          more established issuers, and may be subject to wide price
          fluctuations. Investments in such companies tend to be more volatile
          and somewhat more speculative.



2. HOW DOES THE NONDIVERSIFIED STATUS OF AGGRESSIVE GROWTH PORTFOLIO, CAPITAL
   APPRECIATION PORTFOLIO, GLOBAL LIFE SCIENCES PORTFOLIO AND GLOBAL TECHNOLOGY
   PORTFOLIO AFFECT THEIR RISK?


          Diversification is a way to reduce risk by investing in a broad range
          of stocks or other securities. A "nondiversified" portfolio has the
          ability to take larger positions in a smaller number of issuers.
          Because the appreciation or depreciation of a single stock may have a
          greater impact on the NAV of a nondiversified portfolio, its share
          price can be expected to fluctuate more than a comparable diversified
          portfolio. This fluctuation, if significant, may affect the
          performance of a Portfolio.

RISKS FOR FIXED-INCOME PORTFOLIOS


          Because the Portfolios invest substantially all of their assets in
          fixed-income securities, they are subject to risks such as credit or
          default risks, and decreased value due to interest rate increases. A
          Portfolio's performance may also be affected by risks to certain types
          of investments, such as foreign securities, derivative instruments and
          initial public offerings (IPOs). IPOs and other investment techniques
          may have a magnified performance impact on a portfolio with a small
          asset base. A portfolio may not experience similar performance as its
          assets grow.


The following questions and answers are designed to help you better understand
some of the risks of investing in the Fixed-Income Portfolios.

1. HOW DO THE FIXED-INCOME PORTFOLIOS DIFFER FROM EACH OTHER IN TERMS OF PRIMARY
   INVESTMENT TYPE, CREDIT RISK AND INTEREST RATE RISK?

          Flexible Income Portfolio and High-Yield Portfolio invest primarily in
          corporate bonds. High-Yield Portfolio's credit risk is generally
          higher than Flexible Income Portfolio. Flexible Income Portfolio's
          interest rate risk is generally higher than High-Yield Portfolio.

2. WHAT IS MEANT BY "CREDIT QUALITY" AND WHAT ARE THE RISKS ASSOCIATED WITH IT?

          Credit quality measures the likelihood that the issuer will meet its
          obligations on a bond. One of the fundamental risks associated with
          all fixed-income funds is credit risk, which is the risk that an
          issuer will be unable to make principal and interest payments when
          due. U.S. government securities are generally considered to be the
          safest type of investment in terms of credit risk. Municipal
          obligations generally rank between U.S. government securities and
          corporate debt securities in terms of credit safety. Corporate debt
          securities, particularly those rated below investment grade, present
          the highest credit risk.

3. HOW IS CREDIT QUALITY MEASURED?


          Ratings published by nationally recognized statistical rating agencies
          such as Standard & Poor's Ratings Service and Moody's Investors
          Service, Inc. are widely accepted measures of credit risk. The lower a
          bond issue is rated by an agency, the more credit risk it is
          considered to represent. Lower rated bonds generally pay higher yields
          to compensate investors for the associated risk. Please refer to
          "Explanation of Rating Categories" on pages 58-59 for a description of
          rating categories.

RISKS COMMON TO ALL NON-MONEY MARKET PORTFOLIOS

The following questions and answers discuss risks that apply to all Portfolios
other than Money Market Portfolio.

1. HOW COULD THE PORTFOLIOS' INVESTMENTS IN FOREIGN SECURITIES AFFECT THEIR
   PERFORMANCE?

          The Portfolios may invest without limit in foreign securities either
          indirectly (e.g., depositary receipts) or directly in foreign markets.
          Investments in foreign securities, including those of foreign
          governments, may involve greater risks than investing in domestic
          securities because the Portfolios' performance may depend on issues
          other than the performance of a particular company. These issues
          include:

          - CURRENCY RISK. As long as a Portfolio holds a foreign security, its
            value will be affected by the value of the local currency relative
            to the U.S. dollar. When a Portfolio sells a foreign denominated
            security, its value may be worth less in U.S. dollars even if the
            security increases in value in its home country. U.S. dollar
            denominated securities of foreign issuers may also be affected by
            currency risk.

          - POLITICAL AND ECONOMIC RISK. Foreign investments may be subject to
            heightened political and economic risks, particularly in emerging
            markets which may have relatively unstable governments, immature
            economic structures, national policies restricting investments by
            foreigners, different legal systems, and economies based on only a
            few industries. In some countries, there is the risk that the
            government may take over the assets or operations of a company or
            that the government may impose taxes or limits on the removal of a
            Portfolio's assets from that country.

          - REGULATORY RISK. There may be less government supervision of foreign
            markets. As a result, foreign issuers may not be subject to the
            uniform accounting, auditing and financial reporting standards and
            practices applicable to domestic issuers and there may be less
            publicly available information about foreign issuers.

          - MARKET RISK. Foreign securities markets, particularly those of
            emerging market countries, may be less liquid and more volatile than
            domestic markets. Certain markets may require payment for securities
            before delivery and delays may be encountered in settling securities
            transactions. In some foreign markets, there may not be protection
            against failure by other parties to complete transactions.

          - TRANSACTION COSTS. Costs of buying, selling and holding foreign
            securities, including brokerage, tax and custody costs, may be
            higher than those involved in domestic transactions.


2. ARE THERE SPECIAL RISKS ASSOCIATED WITH INVESTMENTS IN HIGH-YIELD/HIGH-RISK
   BONDS?



          High-yield/high-risk bonds (or "junk" bonds) are bonds rated below
          investment grade by the primary rating agencies such as Standard &
          Poor's and Moody's. The value of lower quality bonds generally is more
          dependent on credit risk, or the ability of the issuer to meet
          interest and principal payments, than investment grade bonds. Issuers
          of high-yield bonds may not be as strong financially as those issuing
          bonds with higher credit ratings and are more vulnerable to real or
          perceived economic changes, political changes or adverse developments
          specific to the issuer.



          The junk bond market can experience sudden and sharp price swings.
          Because Flexible Income Portfolio and High-Yield Portfolio may invest
          a significant portion of their assets in high-yield/high-risk bonds,
          investors should be willing to tolerate a corresponding increase in
          the risk of significant and sudden changes in NAV.



          Please refer to "Explanation of Rating Categories" on pages 58-59 for
          a description of bond rating categories.


            Investment objectives, principal investment strategies and risks  27
<PAGE>

3. HOW DO THE PORTFOLIOS TRY TO REDUCE RISK?


          The Portfolios may use futures, options, swaps and other derivative
          instruments to "hedge" or protect their portfolios from adverse
          movements in securities prices and interest rates. The Portfolios may
          also use a variety of currency hedging techniques, including forward
          currency contracts, to manage exchange rate risk. The portfolio
          managers believe the use of these instruments will benefit the
          Portfolios. However, a Portfolio's performance could be worse than if
          the Portfolio had not used such instruments if a portfolio manager's
          judgement proves incorrect. Risks associated with the use of
          derivative instruments are described in the SAI.



4. WHAT IS "INDUSTRY RISK"?



          Industry risk is the possibility that a group of related stocks will
          decline in price due to industry-specific developments. Companies in
          the same or similar industries may share common characteristics and
          are more likely to react similarly to industry-specific market or
          economic developments. In the life sciences, for example, many
          companies are subject to government regulation and approval of their
          products and services, which may affect their price or availability.
          In addition, the products and services offered by these companies may
          quickly become obsolete in the face of scientific or technological
          developments. The economic outlook of such companies may fluctuate
          dramatically due to changes in regulatory or competitive environments.
          In technology-related industries, competitive pressures may have a
          significant effect on the performance of companies in which Global
          Technology Portfolio may invest. In addition, technology and
          technology-related companies often progress at an accelerated rate,
          and these companies may be subject to short product cycles and
          aggressive pricing which may increase their volatility.



          Global Life Sciences Portfolio invests in a concentrated portfolio,
          which may result in greater exposure to related industries. As a
          result, the Portfolio may be more volatile than a less concentrated
          portfolio. Although Global Technology Portfolio does not "concentrate"
          in a specific group of industries, it may, at times, have significant
          exposure to companies in a variety of technology-related industries.

MONEY MARKET PORTFOLIO

          This section takes a closer look at the investment objective of Money
          Market Portfolio, its principal investment strategies and certain
          risks of investing in the Portfolio. Strategies and policies that are
          noted as "fundamental" cannot be changed without a shareholder vote.

          Money Market Portfolio is subject to certain specific SEC rule
          requirements. Among other things, the Portfolio is limited to
          investing in U.S. dollar-denominated instruments with a remaining
          maturity of 397 days or less (as calculated pursuant to Rule 2a-7
          under the 1940 Act).

INVESTMENT OBJECTIVE AND PRINCIPAL INVESTMENT STRATEGIES

          Money Market Portfolio seeks maximum current income to the extent
          consistent with stability of capital. It pursues its objective by
          investing primarily in high quality debt obligations and obligations
          of financial institutions. Debt obligations may include commercial
          paper, notes and bonds, and variable amount master demand notes.
          Obligations of financial institutions include certificates of deposit
          and time deposits.

          Money Market Portfolio will:

          - invest in high quality, short-term money market instruments that
            present minimal credit risks, as determined by Janus Capital

          - invest only in U.S. dollar-denominated instruments that have a
            remaining maturity of 397 days or less (as calculated pursuant to
            Rule 2a-7 under the 1940 Act)

          - maintain a dollar-weighted average portfolio maturity of 90 days or
            less

TYPES OF INVESTMENTS

          Money Market Portfolio invests primarily in:

          - high quality debt obligations

          - obligations of financial institutions

          The Portfolio may also invest (to a lesser degree) in:

          - U.S. Government Securities (securities issued or guaranteed by the
            U.S. government, its agencies and instrumentalities)

          OBLIGATIONS OF FINANCIAL INSTITUTIONS

          Examples of obligations of financial institutions include:

          - negotiable certificates of deposit, bankers' acceptances, time
            deposits and other obligations of U.S. banks (including savings and
            loan associations) having total assets in excess of one billion
            dollars and U.S. branches of foreign banks having total assets in
            excess of ten billion dollars

          - Eurodollar and Yankee bank obligations (Eurodollar bank obligations
            are dollar-denominated certificates of deposit or time deposits
            issued outside the U.S. capital markets by foreign branches of U.S.
            banks and by foreign banks. Yankee bank obligations are
            dollar-denominated obligations issued in the U.S. capital markets by
            foreign banks)

          - other U.S. dollar-denominated obligations of foreign banks having
            total assets in excess of ten billion dollars that Janus Capital
            believes are of an investment quality comparable to obligations of
            U.S. banks in which the Portfolio may invest

          Foreign, Eurodollar (and to a limited extent, Yankee) bank obligations
          are subject to certain sovereign risks. One such risk is the
          possibility that a foreign government might prevent dollar-denominated
          funds from flowing across its borders. Other risks include: adverse
          political and economic developments in a foreign country; the extent
          and quality of government regulation of financial markets and
          institutions; the imposition of foreign withholding taxes; and
          expropriation or nationalization of foreign issuers.

INVESTMENT TECHNIQUES

          The following is a description of other investment techniques that
          Money Market Portfolio may use:

          PARTICIPATION INTERESTS
          A participation interest gives Money Market Portfolio a proportionate,
          undivided interest in underlying debt securities and sometimes carries
          a demand feature.

          DEMAND FEATURES
          Demand features give Money Market Portfolio the right to resell
          securities at specified periods prior to their maturity dates. Demand
          features may shorten the life of a variable or floating rate security,
          enhance the instrument's credit quality and provide a source of
          liquidity.

          Demand features are often issued by third party financial
          institutions, generally domestic and foreign banks. Accordingly, the
          credit quality and liquidity of Money Market Portfolio's investments
          may be dependent in part on the credit quality of the banks supporting
          Money Market Portfolio's investments. This will result in exposure to
          risks pertaining to the banking industry, including the foreign
          banking industry. Brokerage firms and insurance companies also provide
          certain liquidity and credit support.

          VARIABLE AND FLOATING RATE SECURITIES
          Money Market Portfolio may invest in securities which have variable or
          floating rates of interest. These securities pay interest at rates
          that are adjusted periodically according to a specified formula,
          usually with reference to an interest rate index or market interest
          rate. Variable and floating rate securities are subject to changes in
          value based on changes in market interest rates or changes in the
          issuer's or guarantor's creditworthiness.

 30 Janus Aspen Series
<PAGE>

          MORTGAGE- AND ASSET-BACKED SECURITIES
          Money Market Portfolio may purchase fixed or variable rate
          mortgage-backed securities issued by the Government National Mortgage
          Association, Federal National Mortgage Association, the Federal Home
          Loan Mortgage Corporation, or other governmental or government-related
          entity. The Portfolio may purchase other mortgage- and asset-backed
          securities including securities backed by automobile loans, equipment
          leases or credit card receivables.

          Unlike traditional debt instruments, payments on these securities
          include both interest and a partial payment of principal. Prepayments
          of the principal of underlying loans may shorten the effective
          maturities of these securities and may result in the Portfolio having
          to reinvest proceeds at a lower interest rate.

          REPURCHASE AGREEMENTS
          Money Market Portfolio may enter into collateralized repurchase
          agreements. Repurchase agreements are transactions in which the
          Portfolio purchases securities and simultaneously commits to resell
          those securities to the seller at an agreed-upon price on an
          agreed-upon future date. The repurchase price reflects a market rate
          of interest and is collateralized by cash or securities.

          If the seller of the securities underlying a repurchase agreement
          fails to pay the agreed resale price on the agreed delivery date,
          Money Market Portfolio may incur costs in disposing of the collateral
          and may experience losses if there is any delay in its ability to do
          so.

          must pay. Each of the Portfolios is subject to the following

          the Shares of each Portfolio incur expenses not assumed by Janus
          Capital, including transfer agent and custodian fees and expenses,

          CLASSES OF SHARES


          Each Portfolio currently offers two or three classes of Shares, one of
          which, the Institutional Shares, are offered pursuant to this
          prospectus and are sold under the name Janus Aspen Series. The Shares
          offered by this Prospectus are available only in connection with
          investment in and payments under variable insurance contracts, as well
          as certain qualified retirement plans. Service Shares of the
          Portfolios are offered only in connection with investment in and
          payments under variable insurance contracts as well as certain
          qualified retirement plans that require a fee from Portfolio assets to
          procure distribution and administrative services to contract owners
          and plan participants. Retirement Shares of certain Portfolios are
          offered only to qualified plans using plan service providers that are
          compensated for providing distribution and/or recordkeeping and other
          administrative services provided to plan participants. Because the
          expenses of each class may differ, the performance of each class is
          expected to differ. If you would like additional information about the
          Service Shares or the Retirement Shares, please call 1-800-525-0020.



          During the third quarter of 2000, the Retirement Shares shareholders
          will be asked to approve the spin-off of the Retirement Shares into a
          separate Delaware business trust, Janus Adviser Series. In connection
          with this spin-off, each Portfolio will distribute all of its ordinary
          income and capital gain income earned through the date of the
          spin-off. The distributions will be made for all classes, including
          Institutional Shares. It is anticipated that the spin-off and
          distributions will occur during the third quarter of 2000.


          CONFLICTS OF INTEREST

          The Shares offered by this prospectus are available only to variable
          annuity and variable life separate accounts of insurance companies
          that are unaffiliated with Janus Capital and to certain qualified
          retirement plans. Retirement Shares of the Portfolios (offered through
          a separate prospectus) are available to certain qualified plans.
          Although the Portfolios do not currently anticipate any disadvantages
          to policy owners because each Portfolio offers its shares to such
          entities, there is a possibility that a material conflict may arise.
          The Trustees monitor events in order to identify any disadvantages or
          material irreconcilable conflicts and to determine what action, if
          any, should be taken in response. If a material disadvantage or
          conflict occurs, the Trustees may require one or more insurance
          company separate accounts or qualified plans to withdraw its
          investments in one or more Portfolios or substitute Shares of another
          Portfolio. If this occurs, a Portfolio may be forced to sell its
          securities at disadvantageous prices. In addition, the Trustees may
          refuse to sell Shares of any Portfolio to any separate account or
          qualified plan or may suspend or terminate the offering of a
          Portfolio's Shares if such action is required by law or regulatory
          authority or is in the best interests of that Portfolio's
          shareholders. It is possible that a qualified plan investing in the
          Retirement Shares of the Portfolios could lose its qualified plan
          status under the Internal Revenue Code, which could have adverse tax
          consequences on insurance company separate accounts investing in the
          Shares. Janus Capital intends to monitor such qualified plans and the
          Portfolios may discontinue sales to a qualified plan and require plan
          participants with existing investments in the Retirement Shares to
          redeem those investments if a plan loses (or in the opinion of Janus
          Capital is at risk of losing) its qualified plan status.


          DISTRIBUTION OF EACH PORTFOLIO



          Each Portfolio is distributed by Janus Distributors, Inc., a member of
          the National Association of Securities Dealers, Inc. ("NASD"). To
          obtain information about NASD member firms and their associated
          persons, you may contact NASD Regulation, Inc. at www.nasdr.com, or
          the Public Disclosure Hotline at 800-289-9999. An investor brochure
          containing information describing the Public Disclosure Program is
          available from NASD Regulation, Inc.

                                                         Distributions and taxes


DISTRIBUTIONS

          To avoid taxation of the Portfolios, the Internal Revenue Code
          requires each Portfolio to distribute net income and any net gains
          realized on its investments annually. A Portfolio's income from
          dividends and interest and any net realized short-term gains are paid
          to shareholders as ordinary income dividends. Net realized long-term
          gains are paid to shareholders as capital gains distributions.

PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO


          Each class of each Portfolio, other than Money Market Portfolio,
          distributes substantially all of its investment income at least
          semi-annually and its net realized gains, if any, at least annually.
          All dividends and capital gains distributions from Shares of a
          Portfolio will automatically be reinvested into additional Shares of
          that Portfolio.


          HOW DISTRIBUTIONS AFFECT NAV

          Distributions, other than daily income dividends, are paid to
          shareholders as of the record date of the distribution of a Portfolio,
          regardless of how long the shares have been held. Undistributed income
          and realized gains are included in the daily NAV of a Portfolio's
          Shares. The Share price of a Portfolio drops by the amount of the
          distribution, net of any subsequent market fluctuations. For example,
          assume that on December 31, the Shares of Growth Portfolio declared a
          dividend in the amount of $0.25 per share. If the price of Growth
          Portfolio's Shares was $10.00 on December 30, the share price on
          December 31 would be $9.75, barring market fluctuations.

MONEY MARKET PORTFOLIO

          For the Shares of Money Market Portfolio, dividends representing
          substantially all of the net investment income and any net realized
          gains on sales of securities are declared daily, Saturdays, Sundays
          and holidays included, and distributed on the last business day of
          each month. If a month begins on a Saturday, Sunday or holiday,
          dividends for those days are declared at the end of the preceding
          month and distributed on the first business day of the month. All
          distributions will be automatically reinvested in Shares of the
          Portfolio.

TAXES

          TAXES ON DISTRIBUTIONS

          Because Shares of the Portfolios may be purchased only through
          variable insurance contracts and qualified plans, it is anticipated
          that any income dividends or capital gains distributions made by the
          Shares of a Portfolio will be exempt from current taxation if left to
          accumulate within the variable insurance contract or qualified plan.
          Generally, withdrawals from such contracts may be subject to ordinary
          income tax and, if made before age 59 1/2, a 10% penalty tax. The tax
          status of your investment depends on the features of your qualified
          plan or variable insurance contract. Further information may be found
          in your plan documents or in the prospectus of the separate account
          offering such contract.

          TAXATION OF THE PORTFOLIOS


          Dividends, interest and some gains received by the Portfolios on
          foreign securities may be subject to tax withholding or other foreign
          taxes. The Portfolios may from year to year make the election
          permitted under Section 853 of the Internal Revenue Code to pass
          through such taxes to shareholders as a foreign tax credit. If such
          election is not made, any foreign taxes paid or accrued will represent
          an expense to the Portfolios which will reduce their investment
          income.

<PAGE>


          The Portfolios do not expect to pay any federal income or excise taxes
          because they intend to meet certain requirements of the Internal
          Revenue Code. In addition, because the Shares of each Portfolio are
          sold in connection with variable insurance contracts, each Portfolio
          intends to qualify under the Internal Revenue Code with respect to the
          diversification requirements related to the tax-deferred status of
          insurance company separate accounts.

          INVESTORS MAY NOT PURCHASE OR REDEEM SHARES OF THE PORTFOLIOS
          DIRECTLY. SHARES MAY BE PURCHASED OR REDEEMED ONLY THROUGH VARIABLE
          INSURANCE CONTRACTS OFFERED BY THE SEPARATE ACCOUNTS OF PARTICIPATING
          INSURANCE COMPANIES OR THROUGH QUALIFIED RETIREMENT PLANS. CERTAIN
          PORTFOLIOS MAY NOT BE AVAILABLE IN CONNECTION WITH A PARTICULAR
          CONTRACT AND CERTAIN CONTRACTS MAY LIMIT ALLOCATIONS AMONG THE
          PORTFOLIOS. REFER TO THE PROSPECTUS FOR THE PARTICIPATING INSURANCE
          COMPANY'S SEPARATE ACCOUNT OR YOUR PLAN DOCUMENTS FOR INSTRUCTIONS ON
          PURCHASING OR SELLING OF VARIABLE INSURANCE CONTRACTS AND ON HOW TO
          SELECT SPECIFIC PORTFOLIOS AS INVESTMENT OPTIONS FOR A CONTRACT OR A
          QUALIFIED PLAN.

PRICING OF PORTFOLIO SHARES

          Investments will be processed at the NAV next determined after an
          order is received and accepted by a Portfolio or its agent. In order
          to receive a day's price, your order must be received by the close of
          the regular trading session of the New York Stock Exchange any day
          that the NYSE is open. Securities of the Portfolios other than Money
          Market Portfolio are valued at market value or, if a market quotation
          is not readily available, at their fair value determined in good faith
          under procedures established by and under the supervision of the
          Trustees. Short-term instruments maturing within 60 days are valued at
          amortized cost, which approximates market value. See the SAI for more
          detailed information.

          To the extent a Portfolio holds securities that are primarily listed
          on foreign exchanges that trade on weekends or other days when the
          Portfolios do not price their shares, the NAV of a Portfolio's shares
          may change on days when shareholders will not be able to purchase or
          redeem the Portfolio's shares.

          Money Market Portfolio's securities are valued at their amortized
          cost. Amortized cost valuation involves valuing an instrument at its
          cost and thereafter assuming a constant amortization to maturity (or
          such other date as permitted by Rule 2a-7) of any discount or premium.
          If fluctuating interest rates cause the market value of the portfolio
          to deviate more than 1/2 of 1% from the value determined on the basis
          of amortized cost, the Trustees will consider whether any action, such
          as adjusting the Share's NAV to reflect current market conditions,
          should be initiated to prevent any material dilutive effect on
          shareholders.

PURCHASES

          Purchases of Shares may be made only by the separate accounts of
          insurance companies for the purpose of funding variable insurance
          contracts or by qualified plans. Refer to the prospectus of the
          appropriate insurance company separate account or your plan documents
          for information on how to invest in the Shares of each Portfolio.
          Participating insurance companies and certain other designated
          organizations are authorized to receive purchase orders on the
          Portfolios' behalf.


          The Portfolios do not permit frequent trading or market timing.
          Excessive purchases of Portfolio Shares disrupt portfolio management
          and drive Portfolio expenses higher. Each Portfolio reserves the right
          to reject any specific purchase order. Purchase orders may be refused
          if, in Janus Capital's opinion, they are of a size that would disrupt
          the management of a Portfolio. Although there is no present intention
          to do so, the Portfolios may discontinue sales of their shares if
          management and the Trustees believe that continued sales may adversely
          affect a Portfolio's ability to achieve its investment objective. If
          sales of a Portfolio's Shares are discontinued, it is expected that
          existing policy owners and plan participants invested in that
          Portfolio would be permitted to continue to authorize investment in
          that Portfolio and to reinvest any dividends or capital gains
          distributions, absent highly unusual circumstances.

<PAGE>

REDEMPTIONS

          Redemptions, like purchases, may be effected only through the separate
          accounts of participating insurance companies or through qualified
          plans. Please refer to the appropriate separate account prospectus or
          plan documents for details.

          Shares of any Portfolio may be redeemed on any business day.
          Redemptions are processed at the NAV next calculated after receipt and
          acceptance of the redemption order by the Portfolio or its agent.
          Redemption proceeds will normally be wired to the participating
          insurance company the business day following receipt of the redemption
          order, but in no event later than seven days after receipt of such
          order.


FREQUENT TRADING



          Frequent trading of Portfolio shares in response in short-term
          fluctuations in the market -- also known as "market timing" -- may
          make it very difficult to manage a Portfolio's investments. The
          Portfolios do not permit frequent trading or market timing. When
          market timing occurs, a Portfolio may have to sell portfolio
          securities to have the cash necessary to redeem the market timer's
          shares. This can happen at a time when it is not advantageous to sell
          any securities, which may harm a Portfolio's performance. When large
          dollar amounts are involved, market timing can also make it difficult
          to use long-term investment strategies because the portfolio manager
          cannot predict how much cash a Portfolio will have to invest. When in
          Janus Capital's opinion such activity would have a disruptive effect
          on portfolio management, a Portfolio reserves the right to refuse
          purchase orders and exchanges into a Portfolio by any person, group or
          commonly controlled account. A Portfolio may notify a market timer of
          rejection of a purchase or exchange order after the day the order is
          placed. If a Portfolio allows a market timer to trade Portfolio
          shares, it may require the market timer to enter into a written
          agreement to follow certain procedures and limitations.


SHAREHOLDER COMMUNICATIONS

          Shareholders will receive annual and semiannual reports including the
          financial statements of the Shares of the Portfolios that they have
          authorized for investment. Each report will show the investments owned
          by each Portfolio and the market values thereof, as well as other
          information about the Portfolios and their operations. The Trust's
          fiscal year ends December 31.

                                                            Financial highlights



          The financial highlights tables are intended to help you understand
          the Institutional Shares' financial performance for each of the five
          most recent fiscal years or the life of the Portfolio if less than
          five years. Items 1 through 11 reflect financial results for a single
          Share. Total return in the tables represents the rate that an investor
          would have earned (or lost) on an investment in each of the
          Institutional Shares of the Portfolios (assuming reinvestment of all
          dividends and distributions) but does not include charges and expenses
          attributable to any insurance product. This information has been
          audited by PricewaterhouseCoopers LLP, whose report, along with the
          Portfolios' financial statements, is included in the Annual Report,
          which is available upon request and incorporated by reference into the
          SAI.



          Financial highlights are not presented for Global Life Sciences
          Portfolio and Global Technology Portfolio because the Portfolios had
          not commenced operations as of December 31, 1999.

Glossary of investment terms


          This glossary provides a more detailed description of some of the
          types of securities and other instruments in which the Portfolios may
          invest. The Portfolios may invest in these instruments to the extent
          permitted by their investment objectives and policies. The Portfolios
          are not limited by this discussion and may invest in any other types
          of instruments not precluded by the policies discussed elsewhere in
          this Prospectus. Please refer to the SAI for a more detailed
          discussion of certain instruments.

I. EQUITY AND DEBT SECURITIES

          BONDS are debt securities issued by a company, municipality,
          government or government agency. The issuer of a bond is required to
          pay the holder the amount of the loan (or par value of the bond) at a
          specified maturity and to make scheduled interest payments.

          COMMERCIAL PAPER is a short-term debt obligation with a maturity
          ranging from 1 to 270 days issued by banks, corporations and other
          borrowers to investors seeking to invest idle cash. The Portfolios may
          purchase commercial paper issued in private placements under Section
          4(2) of the Securities Act of 1933.

          COMMON STOCKS are equity securities representing shares of ownership
          in a company and usually carry voting rights and earns dividends.
          Unlike preferred stock, dividends on common stock are not fixed but
          are declared at the discretion of the issuer's board of directors.

          CONVERTIBLE SECURITIES are preferred stocks or bonds that pay a fixed
          dividend or interest payment and are convertible into common stock at
          a specified price or conversion ratio.

          DEBT SECURITIES are securities representing money borrowed that must
          be repaid at a later date. Such securities have specific maturities
          and usually a specific rate of interest or an original purchase
          discount.

          DEPOSITARY RECEIPTS are receipts for shares of a foreign-based
          corporation that entitle the holder to dividends and capital gains on
          the underlying security. Receipts include those issued by domestic
          banks (American Depositary Receipts), foreign banks (Global or
          European Depositary Receipts) and broker-dealers (depositary shares).

          FIXED-INCOME SECURITIES are securities that pay a specified rate of
          return. The term generally includes short-and long-term government,
          corporate and municipal obligations that pay a specified rate of
          interest or coupons for a specified period of time, and preferred
          stock, which pays fixed dividends. Coupon and dividend rates may be
          fixed for the life of the issue or, in the case of adjustable and
          floating rate securities, for a shorter period.


          HIGH-YIELD/HIGH-RISK BONDS are bonds that are rated below investment
          grade by the primary rating agencies (e.g., BB or lower by Standard &
          Poor's and Ba or lower by Moody's). Other terms commonly used to
          describe such bonds include "lower rated bonds," "noninvestment grade
          bonds" and "junk bonds."


          MORTGAGE- AND ASSET-BACKED SECURITIES are shares in a pool of
          mortgages or other debt. These securities are generally pass-through
          securities, which means that principal and interest payments on the
          underlying securities (less servicing fees) are passed through to
          shareholders on a pro rata basis. These securities involve prepayment
          risk, which is the risk that the underlying mortgages or other debt
          may be refinanced or paid off prior to their maturities during periods
          of declining interest rates. In that case, a portfolio manager may
          have to reinvest the proceeds from the securities at a lower rate.
          Potential market gains on a security subject to prepayment risk may be
          more limited than potential market gains on a comparable security that
          is not subject to prepayment risk.

          PASSIVE FOREIGN INVESTMENT COMPANIES (PFICS) are any foreign
          corporations which generate certain amounts of passive income or hold
          certain amounts of assets for the production of passive income.
          Passive income includes dividends, interest, royalties, rents and
          annuities. To avoid taxes and interest that the

 54 Janus Aspen Series
<PAGE>

          Portfolios must pay if these investments are profitable, the
          Portfolios may make various elections permitted by the tax laws. These
          elections could require that the Portfolios recognize taxable income,
          which in turn must be distributed, before the securities are sold and
          before cash is received to pay the distributions.

          PAY-IN-KIND BONDS are debt securities that normally give the issuer an
          option to pay cash at a coupon payment date or give the holder of the
          security a similar bond with the same coupon rate and a face value
          equal to the amount of the coupon payment that would have been made.

          PREFERRED STOCKS are equity securities that generally pay dividends at
          a specified rate and have preference over common stock in the payment
          of dividends and liquidation. Preferred stock generally does not carry
          voting rights.

          REPURCHASE AGREEMENTS involve the purchase of a security by a
          Portfolio and a simultaneous agreement by the seller (generally a bank
          or dealer) to repurchase the security from the Portfolio at a
          specified date or upon demand. This technique offers a method of
          earning income on idle cash. These securities involve the risk that
          the seller will fail to repurchase the security, as agreed. In that
          case, a Portfolio will bear the risk of market value fluctuations
          until the security can be sold and may encounter delays and incur
          costs in liquidating the security.

          REVERSE REPURCHASE AGREEMENTS involve the sale of a security by a
          Portfolio to another party (generally a bank or dealer) in return for
          cash and an agreement by the Portfolio to buy the security back at a
          specified price and time. This technique will be used primarily to
          provide cash to satisfy unusually high redemption requests, or for
          other temporary or emergency purposes.

          RULE 144A SECURITIES are securities that are not registered for sale
          to the general public under the Securities Act of 1933, but that may
          be resold to certain institutional investors.

          STANDBY COMMITMENTS are obligations purchased by a Portfolio from a
          dealer that give the Portfolio the option to sell a security to the
          dealer at a specified price.

          STEP COUPON BONDS are debt securities that trade at a discount from
          their face value and pay coupon interest. The discount from the face
          value depends on the time remaining until cash payments begin,
          prevailing interest rates, liquidity of the security and the perceived
          credit quality of the issuer.

          STRIP BONDS are debt securities that are stripped of their interest
          (usually by a financial intermediary) after the securities are issued.
          The market value of these securities generally fluctuates more in
          response to changes in interest rates than interest-paying securities
          of comparable maturity.

          TENDER OPTION BONDS are generally long-term securities that are
          coupled with an option to tender the securities to a bank,
          broker-dealer or other financial institution at periodic intervals and
          receive the face value of the bond. This type of security is commonly
          used as a means of enhancing the security's liquidity.

          U.S. GOVERNMENT SECURITIES include direct obligations of the U.S.
          government that are supported by its full faith and credit. Treasury
          bills have initial maturities of less than one year, Treasury notes
          have initial maturities of one to ten years and Treasury bonds may be
          issued with any maturity but generally have maturities of at least ten
          years. U.S. government securities also include indirect obligations of
          the U.S. government that are issued by federal agencies and government
          sponsored entities. Unlike Treasury securities, agency securities
          generally are not backed by the full faith and credit of the U.S.
          government. Some agency securities are supported by the right of the
          issuer to borrow from the Treasury, others are supported by the
          discretionary authority of the U.S. government to purchase the
          agency's obligations and others are supported only by the credit of
          the sponsoring agency.

<PAGE>

          VARIABLE AND FLOATING RATE SECURITIES have variable or floating rates
          of interest and, under certain limited circumstances, may have varying
          principal amounts. These securities pay interest at rates that are
          adjusted periodically according to a specified formula, usually with
          reference to some interest rate index or market interest rate. The
          floating rate tends to decrease the security's price sensitivity to
          changes in interest rates.

          WARRANTS are securities, typically issued with preferred stock or
          bonds, that give the holder the right to buy a proportionate amount of
          common stock at a specified price, usually at a price that is higher
          than the market price at the time of issuance of the warrant. The
          right may last for a period of years or indefinitely.

          WHEN-ISSUED, DELAYED DELIVERY AND FORWARD TRANSACTIONS generally
          involve the purchase of a security with payment and delivery at some
          time in the future - i.e., beyond normal settlement. The Portfolios do
          not earn interest on such securities until settlement and bear the
          risk of market value fluctuations in between the purchase and
          settlement dates. New issues of stocks and bonds, private placements
          and U.S. government securities may be sold in this manner.

          ZERO COUPON BONDS are debt securities that do not pay regular interest
          at regular intervals, but are issued at a discount from face value.
          The discount approximates the total amount of interest the security
          will accrue from the date of issuance to maturity. The market value of
          these securities generally fluctuates more in response to changes in
          interest rates than interest-paying securities.

II. FUTURES, OPTIONS AND OTHER DERIVATIVES

          FORWARD CONTRACTS are contracts to purchase or sell a specified amount
          of a financial instrument for an agreed upon price at a specified
          time. Forward contracts are not currently exchange traded and are
          typically negotiated on an individual basis. The Portfolios may enter
          into forward currency contracts to hedge against declines in the value
          of securities denominated in, or whose value is tied to, a currency
          other than the U.S. dollar or to reduce the impact of currency
          appreciation on purchases of such securities. They may also enter into
          forward contracts to purchase or sell securities or other financial
          indices.

          FUTURES CONTRACTS are contracts that obligate the buyer to receive and
          the seller to deliver an instrument or money at a specified price on a
          specified date. The Portfolios may buy and sell futures contracts on
          foreign currencies, securities and financial indices including
          interest rates or an index of U.S. government, foreign government,
          equity or fixed-income securities. The Portfolios may also buy options
          on futures contracts. An option on a futures contract gives the buyer
          the right, but not the obligation, to buy or sell a futures contract
          at a specified price on or before a specified date. Futures contracts
          and options on futures are standardized and traded on designated
          exchanges.

          INDEXED/STRUCTURED SECURITIES are typically short- to
          intermediate-term debt securities whose value at maturity or interest
          rate is linked to currencies, interest rates, equity securities,
          indices, commodity prices or other financial indicators. Such
          securities may be positively or negatively indexed (i.e. their value
          may increase or decrease if the reference index or instrument
          appreciates). Indexed/structured securities may have return
          characteristics similar to direct investments in the underlying
          instruments and may be more volatile than the underlying instruments.
          A Portfolio bears the market risk of an investment in the underlying
          instruments, as well as the credit risk of the issuer.

          INTEREST RATE SWAPS involve the exchange by two parties of their
          respective commitments to pay or receive interest (e.g., an exchange
          of floating rate payments for fixed rate payments).

          INVERSE FLOATERS are debt instruments whose interest rate bears an
          inverse relationship to the interest rate on another instrument or
          index. For example, upon reset the interest rate payable on a security
          may go down when the underlying index has risen. Certain inverse
          floaters may have an interest rate reset

          mechanism that multiplies the effects of change in the underlying
          index. Such mechanism may increase the volatility of the security's
          market value.

          OPTIONS are the right, but not the obligation, to buy or sell a
          specified amount of securities or other assets on or before a fixed
          date at a predetermined price. The Portfolios may purchase and write
          put and call options on securities, securities indices and foreign
          currencies.

Explanation of - rating categories


          The following is a description of credit ratings issued by two of the
          major credit ratings agencies. Credit ratings evaluate only the safety
          of principal and interest payments, not the market value risk of lower
          quality securities. Credit rating agencies may fail to change credit
          ratings to reflect subsequent events on a timely basis. Although Janus
          Capital considers security ratings when making investment decisions,
          it also performs its own investment analysis and does not rely solely
          on the ratings assigned by credit agencies.

                                             and interest.
                AA.......................... High quality; very strong capacity to pay principal and
                                             interest.
                A........................... Strong capacity to pay principal and interest; somewhat more
                                             susceptible to the adverse effects of changing circumstances
                                             and economic conditions.
                BBB......................... Adequate capacity to pay principal and interest; normally
                                             exhibit adequate protection parameters, but adverse economic
                                             conditions or changing circumstances more likely to lead to
                                             a weakened capacity to pay principal and interest than for
                                             higher rated bonds.
                Non-Investment Grade
                BB, B, CCC, CC, C........... Predominantly speculative with respect to the issuer's
                                             capacity to meet required interest and principal payments.
                                             BB - lowest degree of speculation; C - the highest degree of
                                             speculation. Quality and protective characteristics
                                             outweighed by large uncertainties or major risk exposure to
                                             adverse conditions.

                Non-Investment Grade

                                             interest and principal payments not well safeguarded during

                                             low assurance of timely interest and principal payments or
                                             maintenance of other contract terms over time.
                Caa......................... Poor standing, may be in default; elements of danger with
                                             respect to principal or interest payments.
                Ca.......................... Speculative in a high degree; could be in default or have
                                             other marked shortcomings.
                C........................... Lowest-rated; extremely poor prospects of ever attaining
                                             investment standing.

          Unrated securities will be treated as noninvestment grade securities
          unless a portfolio manager determines that such securities are the
          equivalent of investment grade securities. Securities that have
          received ratings from more than one agency are considered investment
          grade if at least one agency has rated the security investment grade.

EQUITY PORTFOLIOS



          The Equity Portfolios are designed for long-term investors who seek
          growth of capital and who can tolerate the greater risks associated
          with common stock investments.



1. WHAT ARE THE INVESTMENT OBJECTIVES OF THE EQUITY PORTFOLIOS?


- --------------------------------------------------------------------------------


          DOMESTIC EQUITY PORTFOLIOS


          - GROWTH PORTFOLIO seeks long-term growth of capital in a manner
            consistent with the preservation of capital.

          - AGGRESSIVE GROWTH PORTFOLIO AND CAPITAL APPRECIATION PORTFOLIO
            seek long-term growth of capital.

          - BALANCED PORTFOLIO seeks long-term capital growth, consistent
            with preservation of capital and balanced by current income.

          - EQUITY INCOME PORTFOLIO seeks current income and long-term growth
            of capital.

          - GROWTH AND INCOME PORTFOLIO seeks long-term capital growth and
            current income.


          GLOBAL/INTERNATIONAL EQUITY PORTFOLIOS


          - INTERNATIONAL GROWTH PORTFOLIO seeks long-term growth of capital.

          - WORLDWIDE GROWTH PORTFOLIO seeks long-term growth of capital in a
            manner consistent with the preservation of capital.

          The Portfolios' Trustees may change these objectives without a
          shareholder vote and the Portfolios will notify you of any changes
          that are material. If there is a material change to a Portfolio's
          objective or policies, you should consider whether that Portfolio
          remains an appropriate investment for you. There is no guarantee that
          a Portfolio will meet its objective.


2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF THE EQUITY PORTFOLIOS?


          The portfolio managers apply a "bottom up" approach in choosing
          investments. In other words, they look for companies with earnings
          growth potential one at a time. If a portfolio manager is unable to
          find investments with earnings growth potential, a significant portion
          of a Portfolio's assets may be in cash or similar investments.

          GROWTH PORTFOLIO invests primarily in common stocks selected for their
          growth potential. Although the Portfolio can invest in companies of
          any size, it generally invests in larger, more established companies.

          AGGRESSIVE GROWTH PORTFOLIO invests primarily in common stocks
          selected for their growth potential, and normally invests at least 50%
          of its equity assets in medium-sized companies.

          CAPITAL APPRECIATION PORTFOLIO invests primarily in common stocks
          selected for their growth potential. The Portfolio may invest in
          companies of any size, from larger, well-established companies to
          smaller, emerging growth companies.

          BALANCED PORTFOLIO normally invests 40-60% of its assets in securities
          selected primarily for their growth potential and 40-60% of its assets
          in securities selected primarily for their income potential. The
          Portfolio will normally invest at least 25% of its assets in
          fixed-income securities.

 2 Janus Aspen Series
<PAGE>

          EQUITY INCOME PORTFOLIO normally emphasizes investments in common
          stocks, and growth potential is a significant investment
          consideration. Normally, it invests at least 65% of its assets in
          income-producing equity securities.

          GROWTH AND INCOME PORTFOLIO normally emphasizes investments in common
          stocks. It will normally invest up to 75% of its assets in equity
          securities selected primarily for their growth potential, and at least
          25% of its assets in securities the portfolio manager believes have
          income potential. Equity securities may make up part of this income
          component if they currently pay dividends or the portfolio manager
          believes they have potential for increasing or commencing dividend
          payments.

          INTERNATIONAL GROWTH PORTFOLIO normally invests at least 65% of its
          total assets in securities of issuers from at least five different
          countries, excluding the United States. Although the Portfolio intends
          to invest substantially all of its assets in issuers located outside
          the United States, it may invest in U.S. issuers and it may at times
          invest all of its assets in fewer than five countries, or even a
          single country.

          WORLDWIDE GROWTH PORTFOLIO invests primarily in common stocks of
          companies of any size throughout the world. The Portfolio normally
          invests in issuers from at least five different countries, including
          the United States. The Portfolio may at times invest in fewer than
          five countries or even a single country.


3. WHAT ARE THE MAIN RISKS OF INVESTING IN THE EQUITY PORTFOLIOS?



          The biggest risk of investing in these Portfolios is that their
          returns may vary, and you could lose money. If you are considering
          investing in any of the Equity Portfolios, remember that they are each
          designed for long-term investors who can accept the risks of investing
          in a portfolio with significant common stock holdings. Common stocks
          tend to be more volatile than other investment choices.



          The value of a Portfolio's holdings may decrease if the value of an
          individual company in the portfolio decreases. The value of a
          Portfolio's holdings could also decrease if the stock market goes
          down. If the value of a Portfolio's holdings decreases, that
          Portfolio's net asset value (NAV) will also decrease, which means if
          you sell your shares in a Portfolio you would get back less money.


          The income component of the BALANCED PORTFOLIO, EQUITY INCOME
          PORTFOLIO AND GROWTH AND INCOME PORTFOLIO includes fixed-income
          securities. A fundamental risk to the income component is that the
          value of these securities will fall if interest rates rise. Generally,
          the value of a fixed-income portfolio will decrease when interest
          rates rise, which means the Portfolio's NAV may likewise decrease.
          Another fundamental risk associated with fixed-income securities is
          credit risk, which is the risk that an issuer of a bond will be unable
          to make principal and interest payments when due.

          INTERNATIONAL GROWTH PORTFOLIO AND WORLDWIDE GROWTH PORTFOLIO may have
          significant exposure to foreign markets. As a result, their returns
          and NAV may be affected to a large degree by fluctuations in currency
          exchange rates or political or economic conditions in a particular
          country.

          AGGRESSIVE GROWTH PORTFOLIO AND CAPITAL APPRECIATION PORTFOLIO are
          nondiversified. In other words, they may hold larger positions in a
          smaller number of securities than a diversified fund. As a result, a
          single security's increase or decrease in value may have a greater
          impact on a Portfolio's NAV and total return.

          An investment in these Portfolios is not a bank deposit and is not
          insured or guaranteed by the Federal Deposit Insurance Corporation or
          any other government agency.


          The following information provides some indication of the risks of
          investing in the Equity Portfolios by showing how each of the Equity
          Portfolios' performance has varied over time. The Growth, Aggressive

FIXED-INCOME PORTFOLIOS

          The Fixed-Income Portfolios are designed for long-term investors who
          primarily seek current income.

1. WHAT ARE THE INVESTMENT OBJECTIVES OF THE FIXED-INCOME PORTFOLIOS?

- --------------------------------------------------------------------------------

          - FLEXIBLE INCOME PORTFOLIO seeks to obtain maximum total return,
            consistent with preservation of capital.

          - HIGH-YIELD PORTFOLIO seeks to obtain high current income. Capital
            appreciation is a secondary objective when consistent with its
            primary objective.

          The Trustees may change these objectives without a shareholder vote
          and the Portfolios will notify you of any changes that are material.
          If there is a material change to a Portfolio's objective or policies,
          you should consider whether it remains an appropriate investment for
          you. There is no guarantee that a Portfolio will meet its objective.

2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF THE FIXED-INCOME PORTFOLIOS?

          In addition to considering economic factors such as the effect of
          interest rates on a Portfolio's investments, the portfolio managers
          apply a "bottom up" approach in choosing investments. In other words,
          they look mostly for income-producing securities that meet their
          investment criteria one at a time. If a portfolio manager is unable to
          find such investments, a Portfolio's assets may be in cash or similar
          investments.


          FLEXIBLE INCOME PORTFOLIO invests primarily in a wide variety of
          income-producing securities such as corporate bonds and notes,
          government securities and preferred stock. As a fundamental policy,
          the Portfolio will invest at least 80% of its assets in
          income-producing securities. The Portfolio may own an unlimited amount
          of high-yield/high-risk bonds, and these securities may be a big part
          of the portfolio.


          HIGH-YIELD PORTFOLIO normally invests at least 65% of its assets in
          high-yield/high-risk fixed-income securities, and may at times invest
          all of its assets in these securities.

3. WHAT ARE THE MAIN RISKS OF INVESTING IN THE FIXED-INCOME PORTFOLIOS?

          Although the Fixed-Income Portfolios may be less volatile than funds
          that invest most of their assets in common stocks, the Portfolios'
          returns and yields will vary, and you could lose money.

          The Portfolios invest in a variety of fixed-income securities. A
          fundamental risk is that the value of these securities will fall if
          interest rates rise. Generally, the value of a fixed-income portfolio
          will decrease when interest rates rise, which means the Portfolio's
          NAV will likewise decrease. Another fundamental risk associated with
          fixed-income funds is credit risk, which is the risk that an issuer
          will be unable to make principal and interest payments when due.


          FLEXIBLE INCOME PORTFOLIO AND HIGH-YIELD PORTFOLIO may invest an
          unlimited amount of their assets in high-yield/high-risk bonds, also
          known as "junk" bonds which may be sensitive to economic changes,
          political changes, or adverse developments specific to the company
          that issued the bond. These bonds generally have a greater credit risk
          than other types of fixed-income securities. Because of these factors,
          the performance and NAV of the Fixed-Income Portfolios may vary
          significantly, depending upon their holdings of junk bonds.


          An investment in these Portfolios is not a bank deposit and is not
          insured or guaranteed by the Federal Deposit Insurance Corporation or
          any other government agency.

<PAGE>

          The following information provides some indication of the risks of
          investing in the Fixed-Income Portfolios by showing how each
          Fixed-Income Portfolio's performance has varied over time. The
          Flexible Income and High-Yield Portfolios Retirement Shares commenced
          operations on May 1, 1997. The returns shown for the Retirement Shares
          of these Portfolios reflect the historical performance of a different
          class of shares (the Institutional Shares) prior to May 1, 1997,
          restated based on the Retirement Shares' fees and expenses on May 1,
          1997 (ignoring any fee and expense limitations). The bar charts depict
          the change in performance from year-to-year during the period
          indicated. The tables compare the average annual returns for the
          Retirement Shares of each Portfolio for the periods indicated to a
          broad-based securities market index.

            consistent with stability of capital.

          The Trustees may change this objective without a shareholder vote and

<PAGE>

3. WHAT ARE THE MAIN RISKS OF INVESTING IN MONEY MARKET PORTFOLIO?

          The Portfolio's yields will vary as the short-term securities in the
          portfolio mature and the proceeds are reinvested in securities with
          different interest rates. Over time, the real value of the Portfolio's
          yield may be eroded by inflation. Although Money Market Portfolio
          invests only in high-quality, short-term money market instruments,
          there is a risk that the value of the securities it holds will fall as
          a result of changes in interest rates, an issuer's actual or perceived
          credit-worthiness or an issuer's ability to meet its obligations.

          An investment in Money Market Portfolio is not a deposit of a bank and
          is not insured or guaranteed by the Federal Deposit Insurance
          Corporation or any other government agency. Although the Portfolio
          seeks to preserve the value of your investment at $1.00 per share, it
          is possible to lose money by investing in Money Market Portfolio.

          The following information provides some indication of the risks of
          investing in Money Market Portfolio by showing how Money Market
          Portfolio's performance has varied over time. The Money Market
          Portfolio Retirement Shares commenced operations on May 1, 1997. The
          returns shown for the Retirement Shares of this Portfolio reflect the
          historical performance of a different class of shares (the
          Institutional Shares) prior to May 1, 1997, restated based on the
          Retirement Share's fees and expenses on May 1, 1997 (ignoring any fee
          and expense limitations). The bar chart depicts the change in
          performance from year to year.

FEES AND EXPENSES

          SHAREHOLDER FEES, such as sales loads, redemption fees or exchange
          fees, are charged directly to an investor's account. All Janus funds
          are no-load investments, so you will not pay any shareholder fees when
          you buy or sell shares of the Portfolios.

          ANNUAL FUND OPERATING EXPENSES are paid out of a Portfolio's assets
          and include fees for portfolio management, maintenance of shareholder
          accounts, shareholder servicing, accounting and other services. You do
          not pay these fees directly but, as the example on the next page
          shows, these costs are borne indirectly by all shareholders.

          This table describes the fees and expenses that you may pay if you buy
          and hold shares of the Portfolios. It is based upon gross expenses
          (without the effect of expense offset arrangements) for the fiscal

   EXAMPLE:

   THE FOLLOWING EXAMPLE IS BASED ON EXPENSES WITHOUT WAIVERS. This example
   is intended to help you compare the cost of investing in the Portfolios
   with the cost of investing in other mutual funds. The example assumes
   that you invest $10,000 in each of the Portfolios for the time periods
   indicated then redeem all of your shares at the end of those periods.
   The example also assumes that your investment has a 5% return each year,
   and that the Portfolios' operating expenses remain the same. Although
   your actual costs may be higher or lower, based on these assumptions
   your costs would be:

EQUITY PORTFOLIOS



          This section takes a closer look at the investment objectives of each
          of the Equity Portfolios, their principal investment strategies and
          certain risks of investing in the Equity Portfolios. Strategies and
          policies that are noted as "fundamental" cannot be changed without a
          shareholder vote.


          Please carefully review the "Risks" section of this Prospectus on
          pages 23-25 for a discussion of risks associated with certain
          investment techniques. We've also included a Glossary with
          descriptions of investment terms used throughout this Prospectus.

INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES


DOMESTIC EQUITY PORTFOLIOS


          GROWTH PORTFOLIO
          Growth Portfolio seeks long-term growth of capital in a manner
          consistent with the preservation of capital. It pursues its objective
          by investing primarily in common stocks selected for their growth
          potential. Although the Portfolio can invest in companies of any size,
          it generally invests in larger, more established companies.

          AGGRESSIVE GROWTH PORTFOLIO

          Aggressive Growth Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in common stocks selected
          for their growth potential, and normally invests at least 50% of its
          equity assets in medium-sized companies. Medium-sized companies are
          those whose market capitalization falls within the range of companies
          in the S&P MidCap 400 Index. Market capitalization is a commonly used
          measure of the size and value of a company. The market capitalizations
          within the Index will vary, but as of December 31, 1999, they ranged
          from approximately $170 million to $37 billion.


            Investment objectives, principal investment strategies and risks  15
<PAGE>

          CAPITAL APPRECIATION PORTFOLIO
          Capital Appreciation Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in common stocks selected
          for their growth potential. The Portfolio may invest in companies of
          any size, from larger, well-established companies to smaller, emerging
          growth companies.

          BALANCED PORTFOLIO
          Balanced Portfolio seeks long-term capital growth, consistent with
          preservation of capital and balanced by current income. It pursues its
          objective by normally investing 40-60% of its assets in securities
          selected primarily for their growth potential and 40-60% of its assets
          in securities selected primarily for their income potential. This
          Portfolio normally invests at least 25% of its assets in fixed-income
          securities.

          EQUITY INCOME PORTFOLIO
          Equity Income Portfolio seeks current income and long-term growth of
          capital. It pursues its objective by normally emphasizing investments
          in common stock, and growth potential is a significant investment
          consideration. The Portfolio tries to provide a lower level of
          volatility than the S&P 500 Index. Normally, it invests at least 65%
          of its assets in income-producing equity securities including common
          and preferred stocks, warrants and securities that are convertible to
          common or preferred stocks.

          GROWTH AND INCOME PORTFOLIO
          Growth and Income Portfolio seeks long-term capital growth and current
          income. It normally emphasizes investments in common stocks. It will
          normally invest up to 75% of its assets in equity securities selected
          primarily for their growth potential, and at least 25% of its assets
          in securities the portfolio manager believes have income potential.
          Because of this investment strategy, the Portfolio is not designed for
          investors who need consistent income.


GLOBAL/INTERNATIONAL EQUITY PORTFOLIOS


          INTERNATIONAL GROWTH PORTFOLIO
          International Growth Portfolio seeks long-term growth of capital.
          Normally, the Portfolio pursues its objective by investing at least
          65% of its total assets in securities of issuers from at least five
          different countries, excluding the United States. Although the
          Portfolio intends to invest substantially all of its assets in issuers
          located outside the United States, it may at times invest in U.S.
          issuers and it may at times invest all of its assets in fewer than
          five countries or even a single country.

          WORLDWIDE GROWTH PORTFOLIO
          Worldwide Growth Portfolio seeks long-term growth of capital in a
          manner consistent with the preservation of capital. It pursues its
          objective by investing primarily in common stocks of companies of any
          size throughout the world. The Portfolio normally invests in issuers
          from at least five different countries, including the United States.
          The Portfolio may at times invest in fewer than five countries or even
          a single country.

The following questions and answers are designed to help you better understand
the Equity Portfolios' principal investment strategies.


1. HOW ARE COMMON STOCKS SELECTED?


          Each of the Portfolios may invest substantially all of its assets in
          common stocks if its portfolio manager believes that common stocks
          will appreciate in value. The portfolio managers generally take a
          "bottom up" approach to selecting companies. In other words, they seek
          to identify individual companies with earnings growth potential that
          may not be recognized by the market at large. They make this
          assessment by looking at companies one at a time, regardless of size,
          country of organization, place of principal business activity, or
          other similar selection criteria. Except for Balanced Portfolio,
          Equity Income Portfolio and Growth and Income Portfolio realization of
          income is not a significant consideration when choosing investments
          for the Portfolios. Income realized on the Portfolios' investments may
          be incidental to their objectives. In the case of Balanced Portfolio,
          Equity Income Portfolio and Growth and Income Portfolio, a portfolio
          manager may consider dividend-paying characteristics to a greater
          degree in selecting common stock.


2. ARE THE SAME CRITERIA USED TO SELECT FOREIGN SECURITIES?

          Generally, yes. The portfolio managers seek companies that meet their
          selection criteria, regardless of where a company is located. Foreign
          securities are generally selected on a stock-by-stock basis without
          regard to any defined allocation among countries or geographic
          regions. However, certain factors such as expected levels of
          inflation, government policies influencing business conditions, the
          outlook for currency relationships, and prospects for economic growth
          among countries, regions or geographic areas may warrant greater
          consideration in selecting foreign securities. There are no
          limitations on the countries in which the Portfolios may invest and
          the Portfolios may at times have significant foreign exposure.

3. WHAT DOES "MARKET CAPITALIZATION" MEAN?


          Market capitalization is the most commonly used measure of the size
          and value of a company. It is computed by multiplying the current
          market price of a share of the company's stock by the total number of
          its shares outstanding. As noted previously, market capitalization is
          an important investment criteria for Aggressive Growth Portfolio.
          Although the other Equity Portfolios offered by this Prospectus do not
          emphasize companies of any particular size, Portfolios with a larger
          asset base are more likely to invest in larger, more established
          issuers.



4. HOW DO BALANCED PORTFOLIO, EQUITY INCOME PORTFOLIO AND GROWTH AND INCOME
   PORTFOLIO DIFFER FROM EACH OTHER?



          Growth and Income Portfolio places a greater emphasis on aggressive
          growth stocks and may derive a greater portion of its income from
          dividend-paying common stocks. Because of these factors, its NAV can
          be expected to fluctuate more than Balanced Portfolio or Equity Income
          Portfolio. Although Equity Income Portfolio invests substantially all
          of its assets in common stocks, it emphasizes investments in dividend-
          paying common stocks and other equity securities characterized by
          relatively greater price stability, and thus may be expected to be
          less volatile than Growth and Income Portfolio, as discussed in more
          detail below. Balanced Portfolio places a greater emphasis on the
          income component of its portfolio and invests to a greater degree in
          securities selected primarily for their income potential. As a result
          it is expected to be less volatile than Equity Income Portfolio and
          Growth and Income Portfolio.



5. HOW DOES EQUITY INCOME PORTFOLIO TRY TO LIMIT PORTFOLIO VOLATILITY?


          Equity Income Portfolio seeks to provide a lower level of volatility
          than the stock market at large, as measured by the S&P 500. The lower
          volatility sought by this Portfolio is expected to result primarily
          from

            Investment objectives, principal investment strategies and risks  17
<PAGE>

          investments in dividend-paying common stocks and other equity
          securities characterized by relatively greater price stability. The
          greater price stability sought by Equity Income Portfolio may be
          characteristic of companies that generate above average free cash
          flows. A company may use free cash flows for a number of purposes
          including commencing or increasing dividend payments, repurchasing its
          own stock or retiring outstanding debt. The portfolio manager also
          considers growth potential in selecting this Portfolio's securities
          and may hold securities selected solely for their growth potential.


6. HOW ARE ASSETS ALLOCATED BETWEEN THE GROWTH AND INCOME COMPONENTS OF BALANCED
   PORTFOLIO'S AND GROWTH AND INCOME PORTFOLIO'S HOLDINGS?


          Balanced Portfolio and Growth and Income Portfolio shift assets
          between the growth and income components of their holdings based on
          the portfolio managers' analysis of relevant market, financial and
          economic conditions. If a portfolio manager believes that growth
          securities will provide better returns than the yields then available
          or expected on income-producing securities, that Portfolio will place
          a greater emphasis on the growth component.


7. WHAT TYPES OF SECURITIES MAKE UP THE GROWTH COMPONENT OF THE BALANCED
   PORTFOLIO, EQUITY INCOME PORTFOLIO AND GROWTH AND INCOME PORTFOLIO?



          The growth component of these portfolios' investments is expected to
          consist primarily of common stocks, but may also include warrants,
          preferred stocks or convertible securities selected primarily for
          their growth potential.



8. WHAT TYPES OF SECURITIES MAKE UP THE INCOME COMPONENT OF BALANCED PORTFOLIO'S
   AND GROWTH AND INCOME PORTFOLIO'S HOLDINGS?



          The income component of Balanced Portfolio and Growth and Income
          Portfolio is expected to consist of securities that the portfolio
          managers believe have income potential. Such securities may include
          equity securities, convertible securities and all types of debt
          securities. Equity securities may be included in the income component
          of a Portfolio if they currently pay dividends or the portfolio
          manager believes they have the potential for either increasing their
          dividends or commencing dividends, if none are currently paid.


FIXED-INCOME PORTFOLIOS

          This section takes a closer look at the investment objectives of each
          of the Fixed-Income Portfolios, their principal investment strategies
          and certain risks of investing in the Fixed-Income Portfolios.
          Strategies and policies that are noted as "fundamental" cannot be
          changed without a shareholder vote.

          Please carefully review the "Risks" section of this Prospectus on
          pages 24-25 for a discussion of risks associated with certain
          investment techniques. We've also included a Glossary with
          descriptions of investment terms used throughout this Prospectus.

INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES

          In addition to considering economic factors such as the effect of
          interest rates on a Portfolio's investments, the portfolio managers
          apply a "bottom up" approach in choosing investments. In other words,
          they look mostly for income-producing securities that meet their
          investment criteria one at a time. If a portfolio manager is unable to
          find such investments, much of a Portfolio's assets may be in cash or
          similar investments.

          FLEXIBLE INCOME PORTFOLIO

          Flexible Income Portfolio seeks to obtain maximum total return,
          consistent with preservation of capital. It pursues its objective by
          primarily investing in a wide variety of income-producing securities
          such as corporate bonds and notes, government securities and preferred
          stock. As a fundamental policy, the Portfolio will invest at least 80%
          of its assets in income-producing securities. The Portfolio may own an
          unlimited amount of high-yield/high-risk bonds, and these may be a big
          part of the portfolio. This Portfolio generates total return from a
          combination of current income and capital appreciation, but income is
          usually the dominant portion.


          HIGH-YIELD PORTFOLIO

          High-Yield Portfolio seeks to obtain high current income. Capital
          appreciation is a secondary objective when consistent with its primary
          objective. It pursues its objectives by normally investing 65% of its
          assets in high-yield/high-risk securities, and may at times invest all
          of its assets in these securities.


The following questions and answers are designed to help you better understand
the Fixed-Income Portfolios' principal investment strategies.

1. HOW DO INTEREST RATES AFFECT THE VALUE OF MY INVESTMENT?

          Generally, a fixed-income security will increase in value when
          interest rates fall and decrease in value when interest rates rise.
          Longer-term securities are generally more sensitive to interest rate
          changes than shorter-term securities, but they generally offer higher
          yields to compensate investors for the associated risks. High-yield
          bond prices are generally less directly responsive to interest rate
          changes than investment grade issues and may not always follow this
          pattern. A bond fund's average-weighted effective maturity and its
          duration are measures of how the fund may react to interest rate
          changes.

2. HOW DO THE FIXED-INCOME PORTFOLIOS MANAGE INTEREST RATE RISK?

          Each Fixed-Income Portfolio may vary the average-weighted effective
          maturity of its assets to reflect its portfolio manager's analysis of
          interest rate trends and other factors. A Portfolio's average-weighted
          effective maturity will tend to be shorter when the portfolio manager
          expects interest rates to rise and longer when its portfolio manager
          expects interest rates to fall. The Portfolios may also use futures,
          options and other derivatives to manage interest rate risks.

3. WHAT IS MEANT BY A PORTFOLIO'S "AVERAGE-WEIGHTED EFFECTIVE MATURITY"?

          The stated maturity of a bond is the date when the issuer must repay
          the bond's entire principal value to an investor. Some types of bonds
          may also have an "effective maturity" that is shorter than the stated
          date due to prepayment or call provisions. Securities without
          prepayment or call provisions generally have an effective maturity
          equal to their stated maturity. Dollar-weighted effective maturity is
          calculated by averaging the effective maturity of bonds held by a
          Portfolio with each effective maturity "weighted" according to the
          percentage of net assets that it represents.

4. WHAT IS MEANT BY A PORTFOLIO'S "DURATION"?

          A bond's duration indicates the time it will take an investor to
          recoup his investment. Unlike average maturity, duration reflects both
          principal and interest payments. Generally, the higher the coupon rate
          on a bond, the lower its duration will be. The duration of a bond
          portfolio is calculated by averaging the duration of bonds held by a
          fund with each duration "weighted" according to the percentage of net
          assets that it represents. Because duration accounts for interest
          payments, a Portfolio's duration is usually shorter than its average
          maturity.

            Investment objectives, principal investment strategies and risks  19
<PAGE>


5. WHAT IS A HIGH-YIELD/HIGH-RISK BOND?



          A high-yield/high-risk bond (also called a "junk" bond) is a bond
          rated below investment grade by major rating agencies (i.e., BB or
          lower by Standard & Poor's or Ba or lower by Moody's) or an unrated
          bond of similar quality. It presents greater risk of default (the
          failure to make timely interest and principal payments) than higher
          quality bonds.


GENERAL PORTFOLIO POLICIES OF THE PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO

          Unless otherwise stated, each of the following policies applies to all
          of the Portfolios other than Money Market Portfolio. The percentage
          limitations included in these policies and elsewhere in this
          Prospectus apply at the time of purchase of the security. So, for
          example, if a Portfolio exceeds a limit as a result of market
          fluctuations or the sale of other securities, it will not be required
          to dispose of any securities.

          CASH POSITION
          When a portfolio manager believes that market conditions are
          unfavorable for profitable investing, or when he or she is otherwise
          unable to locate attractive investment opportunities, the Portfolios'
          cash or similar investments may increase. In other words, the
          Portfolios do not always stay fully invested in stocks and bonds. Cash
          or similar investments generally are a residual - they represent the
          assets that remain after a portfolio manager has committed available
          assets to desirable investment opportunities. However, a portfolio
          manager may also temporarily increase a Portfolio's cash position to
          protect its assets or maintain liquidity. Partly because the portfolio
          managers act independently of each other, the cash positions of the
          Portfolios may vary significantly.

          When a Portfolio's investments in cash or similar investments
          increase, it may not participate in market advances or declines to the
          same extent that it would if the Portfolio remained more fully
          invested in stocks or bonds.

          OTHER TYPES OF INVESTMENTS

          The Equity Portfolios invest primarily in domestic and foreign equity
          securities, which may include preferred stocks, common stocks,
          warrants and securities convertible into common or preferred stocks.
          The Equity Portfolios also invest in domestic and foreign equity
          securities with varying degrees of emphasis on income. The Portfolios
          may also invest to a lesser degree in other types of securities. These
          securities (which are described in the Glossary) may include:


          - debt securities


          - indexed/structured securities



          - high-yield/high-risk bonds (less than 35% of each Portfolio's
            assets)



          - options, futures, forwards, swaps and other types of derivatives for
            hedging purposes or for non-hedging purposes such as seeking to
            enhance return


          - securities purchased on a when-issued, delayed delivery or forward
            commitment basis

          The Fixed-Income Portfolios invest primarily in fixed-income
          securities which may include corporate bonds and notes, government
          securities, preferred stock, high-yield/high-risk fixed-income
          securities and

 20 Janus Aspen Series
<PAGE>

          municipal obligations. The Portfolios may also invest to a lesser
          degree in other types of securities. These securities (which are
          described in the Glossary) may include:

          - common stocks

          - mortgage- and asset-backed securities

          - zero coupon, pay-in-kind and step coupon securities


          - options, futures, forwards, swaps and other types of derivatives for
            hedging purposes or for non-hedging purposes such as seeking to
            enhance return


          - securities purchased on a when-issued, delayed delivery or forward
            commitment basis

          ILLIQUID INVESTMENTS
          Each Portfolio may invest up to 15% of its net assets in illiquid
          investments. An illiquid investment is a security or other position
          that cannot be disposed of quickly in the normal course of business.
          For example, some securities are not registered under U.S. securities
          laws and cannot be sold to the U.S. public because of SEC regulations
          (these are known as "restricted securities"). Under procedures adopted
          by the Portfolios' Trustees, certain restricted securities may be
          deemed liquid, and will not be counted toward this 15% limit.

          FOREIGN SECURITIES
          The Portfolios may invest without limit in foreign equity and debt
          securities. The Portfolios may invest directly in foreign securities
          denominated in a foreign currency and not publicly traded in the
          United States. Other ways of investing in foreign securities include
          depositary receipts or shares, and passive foreign investment
          companies.

          SPECIAL SITUATIONS
          Each Portfolio may invest in special situations. A special situation
          arises when, in the opinion of a Portfolio's manager, the securities
          of a particular issuer will be recognized and appreciate in value due
          to a specific development with respect to that issuer. Developments
          creating a special situation might include, among others, a new
          product or process, a technological breakthrough, a management change
          or other extraordinary corporate event, or differences in market
          supply of and demand for the security. A Portfolio's performance could
          suffer if the anticipated development in a "special situation"
          investment does not occur or does not attract the expected attention.

          PORTFOLIO TURNOVER
          The Portfolios generally intend to purchase securities for long-term
          investment although, to a limited extent, a Portfolio may purchase
          securities in anticipation of relatively short-term price gains.
          Short-term transactions may also result from liquidity needs,
          securities having reached a price or yield objective, changes in
          interest rates or the credit standing of an issuer, or by reason of
          economic or other developments not foreseen at the time of the
          investment decision. A Portfolio may also sell one security and
          simultaneously purchase the same or a comparable security to take
          advantage of short-term differentials in bond yields or securities
          prices. Changes are made in a Portfolio's holdings whenever its
          portfolio manager believes such changes are desirable. Portfolio
          turnover rates are generally not a factor in making buy and sell
          decisions.

            Investment objectives, principal investment strategies and risks  21
<PAGE>

          Increased portfolio turnover may result in higher costs for brokerage
          commissions, dealer mark-ups and other transaction costs and may also
          result in taxable capital gains. Higher costs associated with
          increased portfolio turnover may offset gains in a Portfolio's
          performance.

RISKS FOR EQUITY PORTFOLIOS



          Because the Portfolios may invest substantially all of their assets in
          common stocks, the main risk is the risk that the value of the stocks
          they hold might decrease in response to the activities of an
          individual company or in response to general market and/or economic
          conditions. If this occurs, a Portfolio's share price may also
          decrease. A Portfolio's performance may also be affected by risks
          specific to certain types of investments, such as foreign securities,
          derivative investments, non-investment grade debt securities, initial
          public offerings (IPOs) or companies with relatively small market
          capitalizations. IPOs and other investment techniques may have a
          magnified performance impact on a portfolio with a small asset base. A
          portfolio may not experience similar performance as its assets grow.



The following questions and answers are designed to help you better understand
some of the risks of investing in the Equity Portfolios.


1. THE PORTFOLIOS MAY INVEST IN SMALLER OR NEWER COMPANIES. DOES THIS CREATE ANY
   SPECIAL RISKS?


          Many attractive investment opportunities may be smaller, start-up
          companies offering emerging products or services. Smaller or newer
          companies may suffer more significant losses as well as realize more
          substantial growth than larger or more established issuers because
          they may lack depth of management, be unable to generate funds
          necessary for growth or potential development, or be developing or
          marketing new products or services for which markets are not yet
          established and may never become established. In addition, such
          companies may be insignificant factors in their industries and may
          become subject to intense competition from larger or more established
          companies. Securities of smaller or newer companies may have more
          limited trading markets than the markets for securities of larger or
          more established issuers, and may be subject to wide price
          fluctuations. Investments in such companies tend to be more volatile
          and somewhat more speculative.


2. HOW DOES THE NONDIVERSIFIED STATUS OF AGGRESSIVE GROWTH PORTFOLIO AND CAPITAL
   APPRECIATION PORTFOLIO AFFECT THEIR RISK?

          Diversification is a way to reduce risk by investing in a broad range
          of stocks or other securities. A "nondiversified" portfolio has the
          ability to take larger positions in a smaller number of issuers.
          Because the appreciation or depreciation of a single stock may have a
          greater impact on the NAV of a nondiversified portfolio, its share
          price can be expected to fluctuate more than a comparable diversified
          portfolio. This fluctuation, if significant, may affect the
          performance of a Portfolio.

RISKS FOR FIXED-INCOME PORTFOLIOS


          Because the Portfolios invest substantially all of their assets in
          fixed-income securities, they are subject to risks such as credit or
          default risks, and decreased value due to interest rate increases. A
          Portfolio's performance may also be affected by risks to certain types
          of investments, such as foreign securities, derivative instruments and
          initial public offerings (IPOs). IPOs and other investment techniques
          may have a magnified performance impact on a portfolio with a small
          asset base. A portfolio may not experience similar performance as its
          assets grow.


The following questions and answers are designed to help you better understand
some of the risks of investing in the Fixed-Income Portfolios.

1. HOW DO THE FIXED-INCOME PORTFOLIOS DIFFER FROM EACH OTHER IN TERMS OF PRIMARY
   INVESTMENT TYPE, CREDIT RISK AND INTEREST RATE RISK?

          Flexible Income Portfolio and High-Yield Portfolio invest primarily in
          corporate bonds. High-Yield Portfolio's credit risk is generally
          higher than Flexible Income Portfolio. Flexible Income Portfolio's
          interest rate risk is generally higher than High-Yield Portfolio.

2. WHAT IS MEANT BY "CREDIT QUALITY" AND WHAT ARE THE RISKS ASSOCIATED WITH IT?

          Credit quality measures the likelihood that the issuer will meet its
          obligations on a bond. One of the fundamental risks associated with
          all fixed-income funds is credit risk, which is the risk that an
          issuer will be unable to make principal and interest payments when
          due. U.S. government securities are generally considered to be the
          safest type of investment in terms of credit risk. Municipal
          obligations generally rank between U.S. government securities and
          corporate debt securities in terms of credit safety. Corporate debt
          securities, particularly those rated below investment grade, present
          the highest credit risk.

3. HOW IS CREDIT QUALITY MEASURED?


          Ratings published by nationally recognized statistical rating agencies
          such as Standard & Poor's Ratings Service and Moody's Investors
          Service, Inc. are widely accepted measures of credit risk. The lower a
          bond issue is rated by an agency, the more credit risk it is
          considered to represent. Lower rated bonds generally pay higher yields
          to compensate investors for the associated risk. Please refer to
          "Explanation of Rating Categories" on pages 51-52 for a description of
          rating categories.


RISKS COMMON TO ALL NON-MONEY MARKET PORTFOLIOS

The following questions and answers discuss risks that apply to all Portfolios
other than Money Market Portfolio.

1. HOW COULD THE PORTFOLIOS' INVESTMENTS IN FOREIGN SECURITIES AFFECT THEIR
   PERFORMANCE?

          The Portfolios may invest without limit in foreign securities either
          indirectly (e.g., depositary receipts) or directly in foreign markets.
          Investments in foreign securities, including those of foreign
          governments, may involve greater risks than investing in domestic
          securities because the Portfolios' performance may depend on issues
          other than the performance of a particular company. These issues
          include:

          - CURRENCY RISK. As long as a Portfolio holds a foreign security, its
            value will be affected by the value of the local currency relative
            to the U.S. dollar. When a Portfolio sells a foreign denominated
            security, its value may be worth less in U.S. dollars even if the
            security increases in value in its home country. U.S. dollar
            denominated securities of foreign issuers may also be affected by
            currency risk.

          - POLITICAL AND ECONOMIC RISK. Foreign investments may be subject to
            heightened political and economic risks, particularly in emerging
            markets which may have relatively unstable governments, immature

 24 Janus Aspen Series
<PAGE>

            economic structures, national policies restricting investments by
            foreigners, different legal systems, and economies based on only a
            few industries. In some countries, there is the risk that the
            government may take over the assets or operations of a company or
            that the government may impose taxes or limits on the removal of a
            Portfolio's assets from that country.

          - REGULATORY RISK. There may be less government supervision of foreign
            markets. As a result, foreign issuers may not be subject to the
            uniform accounting, auditing and financial reporting standards and
            practices applicable to domestic issuers and there may be less
            publicly available information about foreign issuers.

          - MARKET RISK. Foreign securities markets, particularly those of
            emerging market countries, may be less liquid and more volatile than
            domestic markets. Certain markets may require payment for securities
            before delivery and delays may be encountered in settling securities
            transactions. In some foreign markets, there may not be protection
            against failure by other parties to complete transactions.

          - TRANSACTION COSTS. Costs of buying, selling and holding foreign
            securities, including brokerage, tax and custody costs, may be
            higher than those involved in domestic transactions.


2. ARE THERE SPECIAL RISKS ASSOCIATED WITH INVESTMENTS IN HIGH-YIELD/HIGH-RISK
   BONDS?



          High-yield/high-risk bonds (or "junk" bonds) are bonds rated below
          investment grade by the primary rating agencies such as Standard &
          Poor's and Moody's. The value of lower quality bonds generally is more
          dependent on credit risk, or the ability of the issuer to meet
          interest and principal payments, than investment grade bonds. Issuers
          of high-yield bonds may not be as strong financially as those issuing
          bonds with higher credit ratings and are more vulnerable to real or
          perceived economic changes, political changes or adverse developments
          specific to the issuer.



          The junk bond market can experience sudden and sharp price swings.
          Because Flexible Income Portfolio and High-Yield Portfolio may invest
          a significant portion of their assets in high-yield/high-risk bonds,
          investors should be willing to tolerate a corresponding increase in
          the risk of significant and sudden changes in NAV.



          Please refer to "Explanation of Rating Categories" on pages 51-52 for
          a description of bond rating categories.


3. HOW DO THE PORTFOLIOS TRY TO REDUCE RISK?


          The Portfolios may use futures, options, swaps and other derivative
          instruments to "hedge" or protect their portfolios from adverse
          movements in securities prices and interest rates. The Portfolios may
          also use a variety of currency hedging techniques, including forward
          currency contracts, to manage exchange rate risk. The portfolio
          managers believe the use of these instruments will benefit the
          Portfolios. However, a Portfolio's performance could be worse than if
          the Portfolio had not used such instruments if a portfolio manager's
          judgement proves incorrect. Risks associated with the use of
          derivative instruments are described in the SAI.

MONEY MARKET PORTFOLIO

          This section takes a closer look at the investment objective of Money
          Market Portfolio, its principal investment strategies and certain
          risks of investing in the Portfolio. Strategies and policies that are
          noted as "fundamental" cannot be changed without a shareholder vote.

          Money Market Portfolio is subject to certain specific SEC rule
          requirements. Among other things, the Portfolio is limited to
          investing in U.S. dollar-denominated instruments with a remaining
          maturity of 397 days or less (as calculated pursuant to Rule 2a-7
          under the 1940 Act).

INVESTMENT OBJECTIVE AND PRINCIPAL INVESTMENT STRATEGIES

          Money Market Portfolio seeks maximum current income to the extent
          consistent with stability of capital. It pursues its objective by
          investing primarily in high quality debt obligations and obligations
          of financial institutions. Debt obligations may include commercial
          paper, notes and bonds, and variable amount master demand notes.
          Obligations of financial institutions include certificates of deposit
          and time deposits.

          Money Market Portfolio will:

          - invest in high quality, short-term money market instruments that
            present minimal credit risks, as determined by Janus Capital

          - invest only in U.S. dollar-denominated instruments that have a
            remaining maturity of 397 days or less (as calculated pursuant to
            Rule 2a-7 under the 1940 Act)

          - maintain a dollar-weighted average portfolio maturity of 90 days or
            less

TYPES OF INVESTMENTS

          Money Market Portfolio invests primarily in:

          - high quality debt obligations

          - obligations of financial institutions

          The Portfolio may also invest (to a lesser degree) in:

          - U.S. Government Securities (securities issued or guaranteed by the
            U.S. government, its agencies and instrumentalities)

          - municipal securities

          DEBT OBLIGATIONS


          The Portfolio may invest in U.S. dollar denominated debt obligations.
          Debt obligations include:


          - commercial paper

          - notes and bonds

          - variable amount master demand notes (the payment obligations on
            these instruments may be backed by securities, swap agreements or
            other assets, by a guarantee of a third party or solely by the
            unsecured promise of the issuer to make payments when due)

          - privately issued commercial paper or other securities that are
            restricted as to disposition under the federal securities laws

<PAGE>

          OBLIGATIONS OF FINANCIAL INSTITUTIONS

          Examples of obligations of financial institutions include:

          - negotiable certificates of deposit, bankers' acceptances, time
            deposits and other obligations of U.S. banks (including savings and
            loan associations) having total assets in excess of one billion
            dollars and U.S. branches of foreign banks having total assets in
            excess of ten billion dollars

          - Eurodollar and Yankee bank obligations (Eurodollar bank obligations
            are dollar-denominated certificates of deposit or time deposits
            issued outside the U.S. capital markets by foreign branches of U.S.
            banks and by foreign banks. Yankee bank obligations are
            dollar-denominated obligations issued in the U.S. capital markets by
            foreign banks)

          - other U.S. dollar-denominated obligations of foreign banks having
            total assets in excess of ten billion dollars that Janus Capital
            believes are of an investment quality comparable to obligations of
            U.S. banks in which the Portfolio may invest

          Foreign, Eurodollar (and to a limited extent, Yankee) bank obligations
          are subject to certain sovereign risks. One such risk is the
          possibility that a foreign government might prevent dollar-denominated
          funds from flowing across its borders. Other risks include: adverse
          political and economic developments in a foreign country; the extent
          and quality of government regulation of financial markets and
          institutions; the imposition of foreign withholding taxes; and
          expropriation or nationalization of foreign issuers.

INVESTMENT TECHNIQUES

          The following is a description of other investment techniques that
          Money Market Portfolio may use:

          PARTICIPATION INTERESTS
          A participation interest gives Money Market Portfolio a proportionate,
          undivided interest in underlying debt securities and sometimes carries
          a demand feature.

          DEMAND FEATURES
          Demand features give Money Market Portfolio the right to resell
          securities at specified periods prior to their maturity dates. Demand
          features may shorten the life of a variable or floating rate security,
          enhance the instrument's credit quality and provide a source of
          liquidity.

          Demand features are often issued by third party financial
          institutions, generally domestic and foreign banks. Accordingly, the
          credit quality and liquidity of Money Market Portfolio's investments
          may be dependent in part on the credit quality of the banks supporting
          Money Market Portfolio's investments. This will result in exposure to
          risks pertaining to the banking industry, including the foreign
          banking industry. Brokerage firms and insurance companies also provide
          certain liquidity and credit support.

          VARIABLE AND FLOATING RATE SECURITIES
          Money Market Portfolio may invest in securities which have variable or
          floating rates of interest. These securities pay interest at rates
          that are adjusted periodically according to a specified formula,
          usually with reference to an interest rate index or market interest
          rate. Variable and floating rate securities are subject to changes in
          value based on changes in market interest rates or changes in the
          issuer's or guarantor's creditworthiness.

            Investment objectives, principal investment strategies and risks  27
<PAGE>

          MORTGAGE- AND ASSET-BACKED SECURITIES
          Money Market Portfolio may purchase fixed or variable rate
          mortgage-backed securities issued by the Government National Mortgage
          Association, Federal National Mortgage Association, the Federal Home
          Loan Mortgage Corporation, or other governmental or government-related
          entity. The Portfolio may purchase other mortgage- and asset-backed
          securities including securities backed by automobile loans, equipment
          leases or credit card receivables.

          Unlike traditional debt instruments, payments on these securities
          include both interest and a partial payment of principal. Prepayments
          of the principal of underlying loans may shorten the effective
          maturities of these securities and may result in the Portfolio having
          to reinvest proceeds at a lower interest rate.

          REPURCHASE AGREEMENTS
          Money Market Portfolio may enter into collateralized repurchase
          agreements. Repurchase agreements are transactions in which the
          Portfolio purchases securities and simultaneously commits to resell
          those securities to the seller at an agreed-upon price on an
          agreed-upon future date. The repurchase price reflects a market rate
          of interest and is collateralized by cash or securities.

          If the seller of the securities underlying a repurchase agreement
          fails to pay the agreed resale price on the agreed delivery date,
          Money Market Portfolio may incur costs in disposing of the collateral
          and may experience losses if there is any delay in its ability to do
          so.

          spells out the management fee and other expenses that the Portfolios
          must pay. Each of the Portfolios is subject to the following

          CLASSES OF SHARES


          Each Portfolio offers two or three classes of shares, one of which,
          the Retirement Shares, are offered pursuant to this prospectus. The
          Shares offered by this prospectus are available only to qualified
          retirement plans using plan service providers that are compensated for
          providing distribution and/or recordkeeping and other administrative
          services provided to plan participants. Institutional Shares of each
          Portfolio are offered only in connection with investment in and
          payments under variable insurance contracts as well as certain
          qualified retirement plans. Service Shares of each Portfolio are
          offered only in connection with investment in and payments under
          variable insurance contracts as well as certain qualified retirement
          plans that require a fee from Portfolio assets to procure distribution
          and administrative services to contract owners and plan participants.
          Because the expenses of each class may differ, the performance of each
          class is expected to differ. If you would like additional information
          about the Institutional Shares, please call 1-800-525-0020.



          SPIN-OFF OF RETIREMENT SHARES



          During the third quarter of 2000, the Retirement Shares shareholders
          will be asked to approve the spin-off of the Retirement Shares into a
          separate Delaware business trust, Janus Adviser Series. In connection
          with this spin-off, each Portfolio will distribute all of its ordinary
          income and capital gain income earned through the date of the
          spin-off. The distributions will be made for all classes, including
          Retirement Shares. It is anticipated that the spin-off and
          distributions will occur during the third quarter of 2000.


          PARTICIPANT ADMINISTRATION FEE


          Janus Service Corporation, the Trust's transfer agent, receives a
          participant administration fee at an annual rate of up to 0.25% of the
          average daily net assets of the Shares of each Portfolio for providing
          or procuring recordkeeping, subaccounting and other administrative
          services to plan participants who invest in the Shares. Janus Service
          expects to use this fee to compensate qualified plan service providers
          for providing these services.


          DISTRIBUTION FEE

          Under a distribution and service plan adopted in accordance with Rule
          12b-1 under the 1940 Act, the Shares may pay Janus Distributors, Inc.,
          the Trust's distributor, a fee at an annual rate of up to 0.25% of the
          average daily net assets of the Shares of a Portfolio. Under the terms
          of the Plan, the Trust is authorized to make payments to Janus
          Distributors for remittance to qualified plan service providers as
          compensation for distribution and shareholder servicing performed by
          such service providers. Because 12b-1 fees are paid out of the
          Retirement Shares' assets on an ongoing basis, they will increase the
          cost of your investment and may cost you more than paying other types
          of sales charges.

          CONFLICTS OF INTEREST

          The Shares offered by this prospectus are available only to qualified
          plans. Institutional Shares (offered through a separate prospectus)
          are available to variable annuity and variable life separate accounts
          of insurance companies unaffiliated with Janus Capital and to certain
          qualified retirement plans. Although the Portfolios do not currently
          anticipate any disadvantages to policy owners or plan participants
          because each Portfolio offers its shares to such entities, there is a
          possibility that a material conflict may arise. The Trustees monitor
          events in order to identify any disadvantages or material
          irreconcilable conflicts and to determine what action, if any, should
          be taken in response. If a material disadvantage or conflict occurs,
          the Trustees may require one or more insurance company separate
          accounts or qualified plans to withdraw

                                                           Other information  35
<PAGE>

          its investments in one or more Portfolios or substitute Shares of
          another Portfolio. If this occurs, a Portfolio may be forced to sell
          its securities at disadvantageous prices. In addition, the Trustees
          may refuse to sell Shares of any Portfolio to any separate account or
          qualified plan or may suspend or terminate the offering of a
          Portfolio's Shares if such action is required by law or regulatory
          authority or is in the best interests of that Portfolio's
          shareholders.


          DISTRIBUTION OF EACH PORTFOLIO



          Each Portfolio is distributed by Janus Distributors, Inc., a member of
          the National Association of Securities Dealers, Inc. ("NASD"). To
          obtain information about NASD member firms and their associated
          persons, you may contact NASD Regulation, Inc. at www.nasdr.com, or
          the Public Disclosure Hotline at 800-289-9999. An investor brochure
          containing information describing the Public Disclosure Program is
          available from NASD Regulation, Inc.

                                                         Distributions and taxes

DISTRIBUTIONS

          To avoid taxation of the Portfolios, the Internal Revenue Code
          requires each Portfolio to distribute net income and any net gains
          realized on its investments annually. A Portfolio's income from
          dividends and interest and any net realized short-term gains are paid
          to shareholders as ordinary income dividends. Net realized long-term
          gains are paid to shareholders as capital gains distributions.

PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO


          Each class of each Portfolio, other than Money Market Portfolio,
          distributes substantially all of its investment income at least
          semi-annually and its net realized gains, if any, at least annually.
          All dividends and capital gains distributions from Shares of a
          Portfolio will automatically be reinvested into additional Shares of
          that Portfolio.


          HOW DISTRIBUTIONS AFFECT NAV

          Distributions, other than daily income dividends, are paid to
          shareholders as of the record date of the distribution of a Portfolio,
          regardless of how long the shares have been held. Undistributed income
          and realized gains are included in the daily NAV of a Portfolio's
          Shares. The Share price of a Portfolio drops by the amount of the
          distribution, net of any subsequent market fluctuations. For example,
          assume that on December 31, the Shares of Growth Portfolio declared a
          dividend in the amount of $0.25 per share. If the price of Growth
          Portfolio's Shares was $10.00 on December 30, the share price on
          December 31 would be $9.75, barring market fluctuations.

MONEY MARKET PORTFOLIO

          For the Shares of Money Market Portfolio, dividends representing
          substantially all of the net investment income and any net realized
          gains on sales of securities are declared daily, Saturdays, Sundays
          and holidays included, and distributed on the last business day of
          each month. If a month begins on a Saturday, Sunday or holiday,
          dividends for those days are declared at the end of the preceding
          month and distributed on the first business day of the month. All
          distributions will be automatically reinvested in Shares of the
          Portfolio.

TAXES

          TAXES ON DISTRIBUTIONS

          Because Shares of the Portfolios may be purchased only through
          qualified plans, it is anticipated that any income dividends or
          capital gains distributions made by the Shares of a Portfolio will be
          exempt from current taxation if left to accumulate within the
          qualified plan. Generally, withdrawals from qualified plans may be
          subject to ordinary income tax and, if made before age 59 1/2, a 10%
          penalty tax. The tax status of your investment depends on the features
          of your qualified plan. For further information, please contact your
          plan sponsor.

          TAXATION OF THE PORTFOLIOS


          Dividends, interest and some gains received by the Portfolios on
          foreign securities may be subject to tax withholding or other foreign
          taxes. The Portfolios may from year to year make the election
          permitted under Section 853 of the Internal Revenue Code to pass
          through such taxes to shareholders as a foreign tax credit. If such
          election is not made, any foreign taxes paid or accrued will represent
          an expense to the Portfolios which will reduce their investment
          income.


                                                     Distributions and taxes  37
<PAGE>


          The Portfolios do not expect to pay any federal income or excise taxes
          because they intend to meet certain requirements of the Internal
          Revenue Code. In addition, because a class of shares of each Portfolio
          are sold in connection with variable life insurance contracts, each
          Portfolio intends to qualify under the Internal Revenue Code with
          respect to the diversification requirements related to the
          tax-deferred status of insurance company separate accounts.

          INVESTORS MAY NOT PURCHASE OR REDEEM SHARES OF THE PORTFOLIOS
          DIRECTLY. SHARES MAY BE PURCHASED OR REDEEMED ONLY THROUGH QUALIFIED
          RETIREMENT PLANS. CERTAIN PORTFOLIOS MAY NOT BE AVAILABLE IN
          CONNECTION WITH A PARTICULAR QUALIFIED PLAN AND CERTAIN QUALIFIED
          PLANS MAY LIMIT ALLOCATIONS AMONG THE PORTFOLIOS. REFER TO YOUR PLAN
          DOCUMENTS FOR INSTRUCTIONS ON HOW TO SELECT SPECIFIC PORTFOLIOS AS
          INVESTMENT OPTIONS FOR A QUALIFIED PLAN.

PRICING OF PORTFOLIO SHARES

          Investments will be processed at the NAV next determined after an
          order is received and accepted by a Portfolio or its agent. In order
          to receive a day's price, your order must be received by the close of
          the regular trading session of the New York Stock Exchange any day
          that the NYSE is open. Securities of the Portfolios other than Money
          Market Portfolio are valued at market value or, if a market quotation
          is not readily available, at their fair value determined in good faith
          under procedures established by and under the supervision of the
          Trustees. Short-term instruments maturing within 60 days are valued at
          amortized cost, which approximates market value. See the SAI for more
          detailed information.

          To the extent a Portfolio holds securities that are primarily listed
          on foreign exchanges that trade on weekends or other days when the
          Portfolios do not price their shares, the NAV of a Portfolio's shares
          may change on days when shareholders will not be able to purchase or
          redeem the Portfolio's shares.

          Money Market Portfolio's securities are valued at their amortized
          cost. Amortized cost valuation involves valuing an instrument at its
          cost and thereafter assuming a constant amortization to maturity (or
          such other date as permitted by Rule 2a-7) of any discount or premium.
          If fluctuating interest rates cause the market value of the portfolio
          to deviate more than 1/2 of 1% from the value determined on the basis
          of amortized cost, the Trustees will consider whether any action, such
          as adjusting the Share's NAV to reflect current market conditions,
          should be initiated to prevent any material dilutive effect on
          shareholders.

PURCHASES

          Purchases of Shares may be made only by qualified plans. Refer to your
          plan documents for information on how to invest in the Shares of each
          Portfolio. Certain plan service providers are authorized to receive
          purchase orders on the Portfolios' behalf.


          The Portfolios do not permit frequent trading or market timing.
          Excessive purchases of Portfolio Shares disrupt portfolio management
          and drive Portfolio expenses higher. Each Portfolio reserves the right
          to reject any specific purchase order. Purchase orders may be refused
          if, in Janus Capital's opinion, they are of a size that would disrupt
          the management of a Portfolio. Although there is no present intention
          to do so, the Portfolios may discontinue sales of their shares if
          management and the Trustees believe that continued sales may adversely
          affect a Portfolio's ability to achieve its investment objective. If
          sales of a Portfolio's Shares are discontinued, it is expected that
          existing participants invested in that Portfolio would be permitted to
          continue to authorize investment in that Portfolio and to reinvest any
          dividends or capital gains distributions, absent highly unusual
          circumstances. The Portfolios may discontinue sales to a qualified
          plan and require plan participants with existing investments in the
          Shares to redeem those investments if the plan loses (or in the
          opinion of Janus Capital, is at risk of losing) its qualified plan
          status.


REDEMPTIONS

          Redemptions, like purchases, may be effected only through qualified
          plans. Please refer to the appropriate plan documents for details.

                                                         Shareholder's guide  39
<PAGE>

          Shares of any Portfolio may be redeemed on any business day.
          Redemptions are processed at the NAV next calculated after receipt and
          acceptance of the redemption order by the Portfolio or its agent.
          Redemption proceeds will normally be wired the business day following
          receipt of the redemption order, but in no event later than seven days
          after receipt of such order.


FREQUENT TRADING



          Frequent trading of Portfolio shares in response in short-term
          fluctuations in the market -- also known as "market timing" -- may
          make it very difficult to manage a Portfolio's investments. The
          Portfolios do not permit frequent trading or market timing. When
          market timing occurs, a Portfolio may have to sell portfolio
          securities to have the cash necessary to redeem the market timer's
          shares. This can happen at a time when it is not advantageous to sell
          any securities, which may harm a Portfolio's performance. When large
          dollar amounts are involved, market timing can also make it difficult
          to use long-term investment strategies because the portfolio manager
          cannot predict how much cash a Portfolio will have to invest. When in
          Janus Capital's opinion such activity would have a disruptive effect
          on portfolio management, a Portfolio reserves the right to refuse
          purchase orders and exchanges into a Portfolio by any person, group or
          commonly controlled account. A Portfolio may notify a market timer of
          rejection of a purchase or exchange order after the day the order is
          placed. If a Portfolio allows a market timer to trade Portfolio
          shares, it may require the market timer to enter into a written
          agreement to follow certain procedures and limitations.


SHAREHOLDER COMMUNICATIONS

          Shareholders will receive annual and semiannual reports including the
          financial statements of the Shares of the Portfolios that they have
          authorized for investment. Each report will show the investments owned
          by each Portfolio and the market values thereof, as well as other
          information about the Portfolios and their operations. The Trust's
          fiscal year ends December 31.

          The financial highlights tables are intended to help you understand
          the Retirement Shares' financial performance from inception of the
          Shares through December 31st of each fiscal period shown. Items 1
          through 9 reflect financial results for a single Share. The total
          returns in the tables represent the rate that an investor would have
          earned (or lost) on an investment in the Retirement Shares of the
          Portfolios (assuming reinvestment of all dividends and distributions).
          This information has been audited by PricewaterhouseCoopers LLP, whose
          report, along with the Portfolios' financial statements, are included
          in the Annual Report, which is available upon request and incorporated
          by reference into the SAI.

                                                    Glossary of investment terms

          This glossary provides a more detailed description of some of the
          types of securities and other instruments in which the Portfolios may
          invest. The Portfolios may invest in these instruments to the extent
          permitted by their investment objectives and policies. The Portfolios
          are not limited by this discussion and may invest in any other types
          of instruments not precluded by the policies discussed elsewhere in
          this Prospectus. Please refer to the SAI for a more detailed
          discussion of certain instruments.

I. EQUITY AND DEBT SECURITIES

          BONDS are debt securities issued by a company, municipality,
          government or government agency. The issuer of a bond is required to
          pay the holder the amount of the loan (or par value of the bond) at a
          specified maturity and to make scheduled interest payments.

          COMMERCIAL PAPER is a short-term debt obligation with a maturity
          ranging from 1 to 270 days issued by banks, corporations and other
          borrowers to investors seeking to invest idle cash. The Portfolios may
          purchase commercial paper issued in private placements under Section
          4(2) of the Securities Act of 1933.

          COMMON STOCKS are equity securities representing shares of ownership
          in a company and usually carry voting rights and earns dividends.
          Unlike preferred stock, dividends on common stock are not fixed but
          are declared at the discretion of the issuer's board of directors.

          CONVERTIBLE SECURITIES are preferred stocks or bonds that pay a fixed
          dividend or interest payment and are convertible into common stock at
          a specified price or conversion ratio.

          DEBT SECURITIES are securities representing money borrowed that must
          be repaid at a later date. Such securities have specific maturities
          and usually a specific rate of interest or an original purchase
          discount.

          DEPOSITARY RECEIPTS are receipts for shares of a foreign-based
          corporation that entitle the holder to dividends and capital gains on
          the underlying security. Receipts include those issued by domestic
          banks (American Depositary Receipts), foreign banks (Global or
          European Depositary Receipts) and broker-dealers (depositary shares).

          FIXED-INCOME SECURITIES are securities that pay a specified rate of
          return. The term generally includes short-and long-term government,
          corporate and municipal obligations that pay a specified rate of
          interest or coupons for a specified period of time, and preferred
          stock, which pays fixed dividends. Coupon and dividend rates may be
          fixed for the life of the issue or, in the case of adjustable and
          floating rate securities, for a shorter period.


          HIGH-YIELD/HIGH-RISK BONDS are bonds that are rated below investment
          grade by the primary rating agencies (e.g., BB or lower by Standard &
          Poor's and Ba or lower by Moody's). Other terms commonly used to
          describe such bonds include "lower rated bonds," "noninvestment grade
          bonds" and "junk bonds."


          MORTGAGE- AND ASSET-BACKED SECURITIES are shares in a pool of
          mortgages or other debt. These securities are generally pass-through
          securities, which means that principal and interest payments on the
          underlying securities (less servicing fees) are passed through to
          shareholders on a pro rata basis. These securities involve prepayment
          risk, which is the risk that the underlying mortgages or other debt
          may be refinanced or paid off prior to their maturities during periods
          of declining interest rates. In that case, a portfolio manager may
          have to reinvest the proceeds from the securities at a lower rate.
          Potential market gains on a security subject to prepayment risk may be
          more limited than potential market gains on a comparable security that
          is not subject to prepayment risk.

          PASSIVE FOREIGN INVESTMENT COMPANIES (PFICS) are any foreign
          corporations which generate certain amounts of passive income or hold
          certain amounts of assets for the production of passive income.
          Passive income includes dividends, interest, royalties, rents and
          annuities. To avoid taxes and interest that the

                                                Glossary of investment terms  47
<PAGE>

          Portfolios must pay if these investments are profitable, the
          Portfolios may make various elections permitted by the tax laws. These
          elections could require that the Portfolios recognize taxable income,
          which in turn must be distributed, before the securities are sold and
          before cash is received to pay the distributions.

          PAY-IN-KIND BONDS are debt securities that normally give the issuer an
          option to pay cash at a coupon payment date or give the holder of the
          security a similar bond with the same coupon rate and a face value
          equal to the amount of the coupon payment that would have been made.

          PREFERRED STOCKS are equity securities that generally pay dividends at
          a specified rate and have preference over common stock in the payment
          of dividends and liquidation. Preferred stock generally does not carry
          voting rights.

          REPURCHASE AGREEMENTS involve the purchase of a security by a
          Portfolio and a simultaneous agreement by the seller (generally a bank
          or dealer) to repurchase the security from the Portfolio at a
          specified date or upon demand. This technique offers a method of
          earning income on idle cash. These securities involve the risk that
          the seller will fail to repurchase the security, as agreed. In that
          case, a Portfolio will bear the risk of market value fluctuations
          until the security can be sold and may encounter delays and incur
          costs in liquidating the security.

          REVERSE REPURCHASE AGREEMENTS involve the sale of a security by a
          Portfolio to another party (generally a bank or dealer) in return for
          cash and an agreement by the Portfolio to buy the security back at a
          specified price and time. This technique will be used primarily to
          provide cash to satisfy unusually high redemption requests, or for
          other temporary or emergency purposes.

          RULE 144A SECURITIES are securities that are not registered for sale
          to the general public under the Securities Act of 1933, but that may
          be resold to certain institutional investors.

          STANDBY COMMITMENTS are obligations purchased by a Portfolio from a
          dealer that give the Portfolio the option to sell a security to the
          dealer at a specified price.

          STEP COUPON BONDS are debt securities that trade at a discount from
          their face value and pay coupon interest. The discount from the face
          value depends on the time remaining until cash payments begin,
          prevailing interest rates, liquidity of the security and the perceived
          credit quality of the issuer.

          STRIP BONDS are debt securities that are stripped of their interest
          (usually by a financial intermediary) after the securities are issued.
          The market value of these securities generally fluctuates more in
          response to changes in interest rates than interest-paying securities
          of comparable maturity.

          TENDER OPTION BONDS are generally long-term securities that are
          coupled with an option to tender the securities to a bank,
          broker-dealer or other financial institution at periodic intervals and
          receive the face value of the bond. This type of security is commonly
          used as a means of enhancing the security's liquidity.

          U.S. GOVERNMENT SECURITIES include direct obligations of the U.S.
          government that are supported by its full faith and credit. Treasury
          bills have initial maturities of less than one year, Treasury notes
          have initial maturities of one to ten years and Treasury bonds may be
          issued with any maturity but generally have maturities of at least ten
          years. U.S. government securities also include indirect obligations of
          the U.S. government that are issued by federal agencies and government
          sponsored entities. Unlike Treasury securities, agency securities
          generally are not backed by the full faith and credit of the U.S.
          government. Some agency securities are supported by the right of the
          issuer to borrow from the Treasury, others are supported by the
          discretionary authority of the U.S. government to purchase the
          agency's obligations and others are supported only by the credit of
          the sponsoring agency.

          VARIABLE AND FLOATING RATE SECURITIES have variable or floating rates
          of interest and, under certain limited circumstances, may have varying
          principal amounts. These securities pay interest at rates that are
          adjusted periodically according to a specified formula, usually with
          reference to some interest rate index or market interest rate. The
          floating rate tends to decrease the security's price sensitivity to
          changes in interest rates.

          WARRANTS are securities, typically issued with preferred stock or
          bonds, that give the holder the right to buy a proportionate amount of
          common stock at a specified price, usually at a price that is higher
          than the market price at the time of issuance of the warrant. The
          right may last for a period of years or indefinitely.

          WHEN-ISSUED, DELAYED DELIVERY AND FORWARD TRANSACTIONS generally
          involve the purchase of a security with payment and delivery at some
          time in the future - i.e., beyond normal settlement. The Portfolios do
          not earn interest on such securities until settlement and bear the
          risk of market value fluctuations in between the purchase and
          settlement dates. New issues of stocks and bonds, private placements
          and U.S. government securities may be sold in this manner.

          ZERO COUPON BONDS are debt securities that do not pay regular interest
          at regular intervals, but are issued at a discount from face value.
          The discount approximates the total amount of interest the security
          will accrue from the date of issuance to maturity. The market value of
          these securities generally fluctuates more in response to changes in
          interest rates than interest-paying securities.

II. FUTURES, OPTIONS AND OTHER DERIVATIVES

          FORWARD CONTRACTS are contracts to purchase or sell a specified amount
          of a financial instrument for an agreed upon price at a specified
          time. Forward contracts are not currently exchange traded and are
          typically negotiated on an individual basis. The Portfolios may enter
          into forward currency contracts to hedge against declines in the value
          of securities denominated in, or whose value is tied to, a currency
          other than the U.S. dollar or to reduce the impact of currency
          appreciation on purchases of such securities. They may also enter into
          forward contracts to purchase or sell securities or other financial
          indices.

          FUTURES CONTRACTS are contracts that obligate the buyer to receive and
          the seller to deliver an instrument or money at a specified price on a
          specified date. The Portfolios may buy and sell futures contracts on
          foreign currencies, securities and financial indices including
          interest rates or an index of U.S. government, foreign government,
          equity or fixed-income securities. The Portfolios may also buy options
          on futures contracts. An option on a futures contract gives the buyer
          the right, but not the obligation, to buy or sell a futures contract
          at a specified price on or before a specified date. Futures contracts
          and options on futures are standardized and traded on designated
          exchanges.

          INDEXED/STRUCTURED SECURITIES are typically short- to
          intermediate-term debt securities whose value at maturity or interest
          rate is linked to currencies, interest rates, equity securities,
          indices, commodity prices or other financial indicators. Such
          securities may be positively or negatively indexed (i.e. their value
          may increase or decrease if the reference index or instrument
          appreciates). Indexed/structured securities may have return
          characteristics similar to direct investments in the underlying
          instruments and may be more volatile than the underlying instruments.
          A Portfolio bears the market risk of an investment in the underlying
          instruments, as well as the credit risk of the issuer.

          INTEREST RATE SWAPS involve the exchange by two parties of their
          respective commitments to pay or receive interest (e.g., an exchange
          of floating rate payments for fixed rate payments).

          INVERSE FLOATERS are debt instruments whose interest rate bears an
          inverse relationship to the interest rate on another instrument or
          index. For example, upon reset the interest rate payable on a security
          may go down when the underlying index has risen. Certain inverse
          floaters may have an interest rate reset

                                                Glossary of investment terms  49
<PAGE>

          mechanism that multiplies the effects of change in the underlying
          index. Such mechanism may increase the volatility of the security's
          market value.

          OPTIONS are the right, but not the obligation, to buy or sell a
          specified amount of securities or other assets on or before a fixed
          date at a predetermined price. The Portfolios may purchase and write
          put and call options on securities, securities indices and foreign
          currencies.

                                                Explanation of rating categories

          The following is a description of credit ratings issued by two of the
          major credit ratings agencies. Credit ratings evaluate only the safety
          of principal and interest payments, not the market value risk of lower
          quality securities. Credit rating agencies may fail to change credit
          ratings to reflect subsequent events on a timely basis. Although Janus
          Capital considers security ratings when making investment decisions,
          it also performs its own investment analysis and does not rely solely
          on the ratings assigned by credit agencies.

                                             and economic conditions.
                BBB......................... Adequate capacity to pay principal and interest; normally
                                             exhibit adequate protection parameters, but adverse economic
                                             conditions or changing circumstances more likely to lead to
                                             a weakened capacity to pay principal and interest than for
                                             higher rated bonds.
                Non-Investment Grade

                                             capacity to meet required interest and principal payments.
                                             BB - lowest degree of speculation; C - the highest degree of
                                             speculation. Quality and protective characteristics
                                             outweighed by large uncertainties or major risk exposure to

                                             maintenance of other contract terms over time.
                Caa......................... Poor standing, may be in default; elements of danger with

                Ca.......................... Speculative in a high degree; could be in default or have
                                             other marked shortcomings.
                C........................... Lowest-rated; extremely poor prospects of ever attaining

          Unrated securities will be treated as noninvestment grade securities
          unless a portfolio manager determines that such securities are the
          equivalent of investment grade securities. Securities that have
          received ratings from more than one agency are considered investment
          grade if at least one agency has rated the security investment grade.

                This prospectus describes thirteen mutual funds (the
                "Portfolios") with a variety of investment objectives, including
                growth of capital, current income and a combination of growth
                and income. Each Portfolio of Janus Aspen Series currently
                offers two or three classes of shares. The Service Shares, (the
                "Shares"), are offered by this prospectus in connection with
                investment in and payments under variable annuity contracts and
                variable life insurance contracts (collectively, "variable
                insurance contracts"), as well as certain qualified retirement
                plans.


                Janus Aspen Series sells and redeems its Shares at net asset
                value without sales charges, commissions or redemption fees.
                Each variable insurance contract involves fees and expenses that
                are not described in this Prospectus. Certain Portfolios may not
                be available in connection with a particular contract and
                certain contracts may limit allocations among the Portfolios.
                See the accompanying contract prospectus for information
                regarding contract fees and expenses and any restrictions on
                purchases or allocations.

                This prospectus contains information that a prospective
                purchaser of a variable insurance contract or plan participant
                should consider in conjunction with the accompanying separate
                account prospectus of the specific insurance company product
                before allocating purchase payments or premiums to the
                Portfolios.

Risk return summary


EQUITY PORTFOLIOS



          The Equity Portfolios are designed for long-term investors who seek
          growth of capital and who can tolerate the greater risks associated
          with common stock investments.



1. WHAT ARE THE INVESTMENT OBJECTIVES OF THE EQUITY PORTFOLIOS?


- --------------------------------------------------------------------------------


          DOMESTIC EQUITY PORTFOLIOS


          - GROWTH PORTFOLIO seeks long-term growth of capital in a manner
            consistent with the preservation of capital.

          - AGGRESSIVE GROWTH PORTFOLIO AND CAPITAL APPRECIATION PORTFOLIO
            seek long-term growth of capital.

          - BALANCED PORTFOLIO seeks long-term capital growth, consistent
            with preservation of capital and balanced by current income.

          - EQUITY INCOME PORTFOLIO seeks current income and long-term growth
            of capital.

          - GROWTH AND INCOME PORTFOLIO seeks long-term capital growth and
            current income.

          GLOBAL/INTERNATIONAL EQUITY PORTFOLIOS


          - INTERNATIONAL GROWTH PORTFOLIO, GLOBAL LIFE SCIENCES PORTFOLIO
            AND GLOBAL TECHNOLOGY PORTFOLIO seek long-term growth of capital.


          - WORLDWIDE GROWTH PORTFOLIO seeks long-term growth of capital in a
            manner consistent with the preservation of capital.

          The Portfolios' Trustees may change these objectives without a
          shareholder vote and the Portfolios will notify you of any changes
          that are material. If there is a material change to a Portfolio's
          objective or policies, you should consider whether that Portfolio
          remains an appropriate investment for you. There is no guarantee that
          a Portfolio will meet its objective.


2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF THE EQUITY PORTFOLIOS?


          The portfolio managers apply a "bottom up" approach in choosing
          investments. In other words, they look for companies with earnings
          growth potential one at a time. If a portfolio manager is unable to
          find investments with earnings growth potential, a significant portion
          of a Portfolio's assets may be in cash or similar investments.

          GROWTH PORTFOLIO invests primarily in common stocks selected for their
          growth potential. Although the Portfolio can invest in companies of
          any size, it generally invests in larger, more established companies.

          AGGRESSIVE GROWTH PORTFOLIO invests primarily in common stocks
          selected for their growth potential, and normally invests at least 50%
          of its equity assets in medium-sized companies.

          CAPITAL APPRECIATION PORTFOLIO invests primarily in common stocks
          selected for their growth potential. The Portfolio may invest in
          companies of any size, from larger, well-established companies to
          smaller, emerging growth companies.

 2 Janus Aspen Series

          BALANCED PORTFOLIO normally invests 40-60% of its assets in securities
          selected primarily for their growth potential and 40-60% of its assets
          in securities selected primarily for their income potential. The
          Portfolio will normally invest at least 25% of its assets in
          fixed-income securities.

          EQUITY INCOME PORTFOLIO normally emphasizes investments in common
          stocks, and growth potential is a significant investment
          consideration. Normally, it invests at least 65% of its assets in
          income-producing equity securities.

          GROWTH AND INCOME PORTFOLIO normally emphasizes investments in common
          stocks. It will normally invest up to 75% of its assets in equity
          securities selected primarily for their growth potential, and at least
          25% of its assets in securities the portfolio manager believes have
          income potential. Equity securities may make up part of this income
          component if they currently pay dividends or the portfolio manager
          believes they have potential for increasing or commencing dividend
          payments.

          INTERNATIONAL GROWTH PORTFOLIO normally invests at least 65% of its
          total assets in securities of issuers from at least five different
          countries, excluding the United States. Although the Portfolio intends
          to invest substantially all of its assets in issuers located outside
          the United States, it may invest in U.S. issuers and it may at times
          invest all of its assets in fewer than five countries, or even a
          single country.

          WORLDWIDE GROWTH PORTFOLIO invests primarily in common stocks of
          companies of any size throughout the world. The Portfolio normally
          invests in issuers from at least five different countries, including
          the United States. The Portfolio may at times invest in fewer than
          five countries or even a single country.


          GLOBAL LIFE SCIENCES PORTFOLIO invests primarily in equity securities
          of U.S. and foreign companies selected for their growth potential.
          Normally, it invests at least 65% of its total assets in securities of
          companies that the portfolio manager believes have a life science
          orientation. Generally speaking, the "life sciences" relate to
          maintaining or improving quality of life. So, for example, companies
          with a "life science orientation" include companies engaged in
          research, development, production or distribution of products or
          services related to health and personal care, medicine or
          pharmaceuticals. As a fundamental policy, the Portfolio normally
          invests at least 25% of its total assets, in the aggregate, in the
          following industry groups: healthcare; pharmaceuticals; agriculture;
          cosmetics/personal care; and biotechnology.



          GLOBAL TECHNOLOGY PORTFOLIO invests primarily in equity securities of
          U.S. and foreign companies selected for their growth potential. Under
          normal circumstances, it invests at least 65% of its total assets in
          securities of companies that the portfolio manager believes will
          benefit significantly from advances or improvements in technology.



3. WHAT ARE THE MAIN RISKS OF INVESTING IN THE EQUITY PORTFOLIOS?



          The biggest risk of investing in these Portfolios is that their
          returns may vary, and you could lose money. If you are considering
          investing in any of the Equity Portfolios, remember that they are each
          designed for long-term investors who can accept the risks of investing
          in a portfolio with significant common stock holdings. Common stocks
          tend to be more volatile than other investment choices.



          The value of a Portfolio's holdings may decrease if the value of an
          individual company in the portfolio decreases. The value of a
          Portfolio's holdings could also decrease if the stock market goes
          down. If the value of a Portfolio's holdings decreases, that
          Portfolio's net asset value (NAV) will also decrease, which means if
          you sell your shares in a Portfolio you would get back less money.


          The income component of the BALANCED PORTFOLIO, EQUITY INCOME
          PORTFOLIO AND GROWTH AND INCOME PORTFOLIO includes fixed-income
          securities. A fundamental risk to the income component is that the
          value of these securities will fall if interest rates rise. Generally,
          the value of a fixed-income portfolio will

                                                          Risk return summary  3
<PAGE>

          decrease when interest rates rise, which means the Portfolio's NAV may
          likewise decrease. Another fundamental risk associated with
          fixed-income securities is credit risk, which is the risk that an
          issuer of a bond will be unable to make principal and interest
          payments when due.


          GLOBAL LIFE SCIENCES PORTFOLIO concentrates its investments in related
          industry groups. Because of this, companies in its portfolio may share
          common characteristics and react similarly to market developments. For
          example, many companies with a life science orientation are highly
          regulated and may be dependent upon certain types of technology. As a
          result, changes in government funding or subsidies, new or anticipated
          legislative changes, or technological advances could affect the value
          of such companies and, therefore, the Portfolio's NAV. The Portfolio's
          returns may be more volatile than those of a less concentrated
          portfolio.



          Although GLOBAL TECHNOLOGY PORTFOLIO does not concentrate its
          investments in specific industries, it may invest in companies related
          in such a way that they react similarly to certain market pressures.
          For example, competition among technology companies may result in
          increasingly aggressive pricing of their products and services, which
          may affect the profitability of companies in the portfolio. In
          addition, because of the rapid pace of technological development,
          products or services developed by companies in the Portfolio's
          portfolio may become rapidly obsolete or have relatively short product
          cycles. As a result, the Portfolio's returns may be considerably more
          volatile than the returns of a fund that does not invest in similarly
          related companies.



          INTERNATIONAL GROWTH PORTFOLIO, WORLDWIDE GROWTH PORTFOLIO, GLOBAL
          LIFE SCIENCES PORTFOLIO AND GLOBAL TECHNOLOGY PORTFOLIO may have
          significant exposure to foreign markets. As a result, their returns
          and NAV may be affected to a large degree by fluctuations in currency
          exchange rates or political or economic conditions in a particular
          country.



          AGGRESSIVE GROWTH PORTFOLIO, CAPITAL APPRECIATION PORTFOLIO, GLOBAL
          LIFE SCIENCES PORTFOLIO AND GLOBAL TECHNOLOGY PORTFOLIO are
          nondiversified. In other words, they may hold larger positions in a
          smaller number of securities than a diversified fund. As a result, a
          single security's increase or decrease in value may have a greater
          impact on a Portfolio's NAV and total return.


          An investment in these Portfolios is not a bank deposit and is not
          insured or guaranteed by the Federal Deposit Insurance Corporation or
          any other government agency.


          The following information provides some indication of the risks of
          investing in the Equity Portfolios by showing how each of the Equity
          Portfolios' performance has varied over time. The Portfolios' Service
          Shares commenced operations on December 31, 1999. The returns shown
          for the Service Shares of these Portfolios reflect the historical
          performance of a different class of shares (the Institutional Shares)
          prior to December 31, 1999, restated based on the Service Shares'
          estimated fees and expenses (ignoring any fee and expense
          limitations). The bar charts depict the change in performance from
          year-to-year during the period indicated but do not include charges
          and expenses attributable to any insurance product which would lower

FIXED-INCOME PORTFOLIOS

          The Fixed-Income Portfolios are designed for long-term investors who
          primarily seek current income.

1. WHAT ARE THE INVESTMENT OBJECTIVES OF THE FIXED-INCOME PORTFOLIOS?

- --------------------------------------------------------------------------------

          - FLEXIBLE INCOME PORTFOLIO seeks to obtain maximum total return,
            consistent with preservation of capital.

          - HIGH-YIELD PORTFOLIO seeks to obtain high current income. Capital
            appreciation is a secondary objective when consistent with its
            primary objective.

          The Trustees may change these objectives without a shareholder vote
          and the Portfolios will notify you of any changes that are material.
          If there is a material change to a Portfolio's objective or policies,
          you should consider whether it remains an appropriate investment for
          you. There is no guarantee that a Portfolio will meet its objective.

2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF THE FIXED-INCOME PORTFOLIOS?

          In addition to considering economic factors such as the effect of
          interest rates on a Portfolio's investments, the portfolio managers
          apply a "bottom up" approach in choosing investments. In other words,
          they look mostly for income-producing securities that meet their
          investment criteria one at a time. If a portfolio manager is unable to
          find such investments, a Portfolio's assets may be in cash or similar
          investments.


          FLEXIBLE INCOME PORTFOLIO invests primarily in a wide variety of
          income-producing securities such as corporate bonds and notes,
          government securities and preferred stock. As a fundamental policy,
          the Portfolio will invest at least 80% of its assets in
          income-producing securities. The Portfolio may own an unlimited amount
          of high-yield/high-risk bonds, and these securities may be a big part
          of the portfolio.


          HIGH-YIELD PORTFOLIO normally invests at least 65% of its assets in
          high-yield/high-risk fixed-income securities, and may at times invest
          all of its assets in these securities.

3. WHAT ARE THE MAIN RISKS OF INVESTING IN THE FIXED-INCOME PORTFOLIOS?

          Although the Fixed-Income Portfolios may be less volatile than funds
          that invest most of their assets in common stocks, the Portfolios'
          returns and yields will vary, and you could lose money.

          The Portfolios invest in a variety of fixed-income securities. A
          fundamental risk is that the value of these securities will fall if
          interest rates rise. Generally, the value of a fixed-income portfolio
          will decrease when interest rates rise, which means the Portfolio's
          NAV will likewise decrease. Another fundamental risk associated with
          fixed-income funds is credit risk, which is the risk that an issuer
          will be unable to make principal and interest payments when due.


          FLEXIBLE INCOME PORTFOLIO AND HIGH-YIELD PORTFOLIO may invest an
          unlimited amount of their assets in high-yield/high-risk bonds, also
          known as "junk" bonds which may be sensitive to economic changes,
          political changes, or adverse developments specific to the company
          that issued the bond. These bonds generally have a greater credit risk
          than other types of fixed-income securities. Because of these factors,
          the performance and NAV of the Fixed-Income Portfolios may vary
          significantly, depending upon their holdings of junk bonds.



          An investment in these Portfolios is not a bank deposit and is not
          insured or guaranteed by the Federal Deposit Insurance Corporation or
          any other government agency.

          The following information provides some indication of the risks of
          investing in the Fixed-Income Portfolios by showing how each
          Fixed-Income Portfolio's performance has varied over time. The
          Portfolio's Service Shares commenced operations on December 31, 1999.
          The returns shown for the Service Shares of these Portfolios reflect
          the historical performance of a different class of shares (the
          Institutional Shares) prior to December 31, 1999, restated based on
          the Service Shares' estimated fees and expenses on (ignoring any fee
          and expense limitations). The bar charts depict the change in
          performance from year-to-year during the period indicated but do not
          include charges and expenses attributable to any insurance product
          which would lower the performance illustrated. The Portfolios do not
          impose any sales or other charges that would affect total return
          computations. Total return figures include the effect of each
          Portfolio's expenses. The tables compare the average annual returns
          for the Service Shares of each Portfolio for the periods indicated to
          a broad-based securities market index.

MONEY MARKET PORTFOLIO

          Money Market Portfolio is designed for investors who seek current
          income.

1. WHAT IS THE INVESTMENT OBJECTIVE OF MONEY MARKET PORTFOLIO?

- --------------------------------------------------------------------------------

          - MONEY MARKET PORTFOLIO seeks maximum current income to the extent
            consistent with stability of capital.

          The Trustees may change this objective without a shareholder vote and
          the Portfolio will notify you of any changes that are material. If
          there is a material change in the Portfolio's objective or policies,
          you should consider whether it remains an appropriate investment for
          you. There is no guarantee that the Portfolio will meet its objective.

2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF MONEY MARKET PORTFOLIO?

          MONEY MARKET PORTFOLIO will invest only in high-quality, short-term
          money market instruments that present minimal credit risks, as
          determined by Janus Capital. The Portfolio invests primarily in high
          quality debt obligations and obligations of financial institutions.
          Debt obligations may include commercial paper, notes and bonds, and
          variable amount master demand notes. Obligations of financial
          institutions include certificates of deposit and time deposits.

3. WHAT ARE THE MAIN RISKS OF INVESTING IN MONEY MARKET PORTFOLIO?

          The Portfolio's yields will vary as the short-term securities in the
          portfolio mature and the proceeds are reinvested in securities with
          different interest rates. Over time, the real value of the Portfolio's
          yield may be eroded by inflation. Although Money Market Portfolio
          invests only in high-quality, short-term money market instruments,
          there is a risk that the value of the securities it holds will fall as
          a result of changes in interest rates, an issuer's actual or perceived
          credit-worthiness or an issuer's ability to meet its obligations.

          An investment in Money Market Portfolio is not a deposit of a bank and
          is not insured or guaranteed by the Federal Deposit Insurance
          Corporation or any other government agency. Although the Portfolio
          seeks to preserve the value of your investment at $1.00 per share, it
          is possible to lose money by investing in Money Market Portfolio.


          The following information provides some indication of the risks of
          investing in Money Market Portfolio by showing how Money Market
          Portfolio's performance has varied over time. The Money Market
          Portfolio Service Shares commenced operations on December 31, 1999.
          The returns shown for the Service Shares of this Portfolio reflect the

          the Service Share's estimated fees and expenses (ignoring any fee and
          expense limitations). The bar chart depicts the change in performance
          from year to year, but does not include charges and expenses
          attributable to any insurance product which would lower the
          performance illustrated. The Portfolio does not impose any sales or
          other charges that would affect total return computations. Total
          return figures include the effect of the Portfolio's expenses.

FEES AND EXPENSES

          SHAREHOLDER FEES, such as sales loads, redemption fees or exchange
          fees, are charged directly to an investor's account. All Janus funds
          are no-load investments, so you will not pay any shareholder fees when
          you buy or sell shares of the Portfolios. However, each variable
          insurance contract involves fees and expenses not described in this
          prospectus. See the accompanying contract prospectus for information
          regarding contract fees and expenses and any restrictions on purchases
          or allocations.

          ANNUAL FUND OPERATING EXPENSES are paid out of a Portfolio's assets
          and include fees for portfolio management, maintenance of shareholder
          accounts, shareholder servicing, accounting and other services. You do
          not pay these fees directly but, as the example on the next page
          shows, these costs are borne indirectly by all shareholders.

          qualified plans that invest in the Shares of the Portfolios in
          understanding the fees and expenses that you may pay as an investor in
          the Shares. OWNERS OF VARIABLE INSURANCE CONTRACTS THAT INVEST IN THE
          SHARES SHOULD REFER TO THE VARIABLE INSURANCE CONTRACT PROSPECTUS FOR
          A DESCRIPTION OF FEES AND EXPENSES, AS THE TABLE AND EXAMPLE DO NOT

   (2) Expenses are based on the estimated expenses that the new Service
       Shares Class of each Portfolio expects to incur in its initial fiscal
       year. Expenses are stated both with and without contractual waivers by
       Janus Capital. Waivers, if applicable, are first applied against the
       management fee and then against other expenses, and will continue
       until at least the next annual renewal of the advisory agreement. All
       expenses are shown without the effect of any expense offset

   EXAMPLE:

   THE FOLLOWING EXAMPLE IS BASED ON EXPENSES WITHOUT WAIVERS (IF ANY).
   This example is intended to help you compare the cost of investing in
   the Portfolios with the cost of investing in other mutual funds. The
   example assumes that you invest $10,000 in each of the Portfolios for
   the time periods indicated then redeem all of your shares at the end of
   those periods. The example also assumes that your investment has a 5%
   return each year, and that the Portfolios' operating expenses remain the
   same. Although your actual costs may be higher or lower, based on these
   assumptions your costs would be:

EQUITY PORTFOLIOS



          This section takes a closer look at the investment objectives of each
          of the Equity Portfolios, their principal investment strategies and
          certain risks of investing in the Equity Portfolios. Strategies and
          policies that are noted as "fundamental" cannot be changed without a
          shareholder vote.


          Please carefully review the "Risks" section of this Prospectus on
          pages 25-28 for a discussion of risks associated with certain
          investment techniques. We've also included a Glossary with
          descriptions of investment terms used throughout this Prospectus.

INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES


DOMESTIC EQUITY PORTFOLIOS


          GROWTH PORTFOLIO
          Growth Portfolio seeks long-term growth of capital in a manner
          consistent with the preservation of capital. It pursues its objective
          by investing primarily in common stocks selected for their growth
          potential. Although the Portfolio can invest in companies of any size,
          it generally invests in larger, more established companies.

          AGGRESSIVE GROWTH PORTFOLIO

          Aggressive Growth Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in common stocks selected
          for their growth potential, and normally invests at least 50% of its
          equity assets in medium-sized companies. Medium-sized companies are
          those whose market capitalization falls within the range of companies
          in the S&P MidCap 400 Index. Market capitalization is a commonly


 16 Janus Aspen Series
<PAGE>


          used measure of the size and value of a company. The market
          capitalizations within the Index will vary, but as of December 31,
          1999, they ranged from approximately $170 million to $37 billion.


          CAPITAL APPRECIATION PORTFOLIO
          Capital Appreciation Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in common stocks selected
          for their growth potential. The Portfolio may invest in companies of
          any size, from larger, well-established companies to smaller, emerging
          growth companies.

          BALANCED PORTFOLIO
          Balanced Portfolio seeks long-term capital growth, consistent with
          preservation of capital and balanced by current income. It pursues its
          objective by normally investing 40-60% of its assets in securities
          selected primarily for their growth potential and 40-60% of its assets
          in securities selected primarily for their income potential. This
          Portfolio normally invests at least 25% of its assets in fixed-income
          securities.

          EQUITY INCOME PORTFOLIO
          Equity Income Portfolio seeks current income and long-term growth of
          capital. It pursues its objective by normally emphasizing investments
          in common stock, and growth potential is a significant investment
          consideration. The Portfolio tries to provide a lower level of
          volatility than the S&P 500 Index. Normally, it invests at least 65%
          of its assets in income-producing equity securities including common
          and preferred stocks, warrants and securities that are convertible to
          common or preferred stocks.

          GROWTH AND INCOME PORTFOLIO
          Growth and Income Portfolio seeks long-term capital growth and current
          income. It normally emphasizes investments in common stocks. It will
          normally invest up to 75% of its assets in equity securities selected
          primarily for their growth potential, and at least 25% of its assets
          in securities the portfolio manager believes have income potential.
          Because of this investment strategy, the Portfolio is not designed for
          investors who need consistent income.


GLOBAL/INTERNATIONAL EQUITY PORTFOLIOS


          INTERNATIONAL GROWTH PORTFOLIO
          International Growth Portfolio seeks long-term growth of capital.
          Normally, the Portfolio pursues its objective by investing at least
          65% of its total assets in securities of issuers from at least five
          different countries, excluding the United States. Although the
          Portfolio intends to invest substantially all of its assets in issuers
          located outside the United States, it may at times invest in U.S.
          issuers and it may at times invest all of its assets in fewer than
          five countries or even a single country.

          WORLDWIDE GROWTH PORTFOLIO
          Worldwide Growth Portfolio seeks long-term growth of capital in a
          manner consistent with the preservation of capital. It pursues its
          objective by investing primarily in common stocks of companies of any
          size throughout the world. The Portfolio normally invests in issuers
          from at least five different countries, including the United States.
          The Portfolio may at times invest in fewer than five countries or even
          a single country.

          GLOBAL LIFE SCIENCES PORTFOLIO


          Global Life Sciences Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in equity securities of
          U.S. and foreign companies selected for their growth potential.
          Normally, it invests at least 65% of its total assets in securities of
          companies that the portfolio manager believes have a life science
          orientation. As a fundamental policy, the Portfolio normally invests
          at least 25% of its total assets, in the aggregate, in the following
          industry groups: health care; pharmaceuticals; agriculture;
          cosmetics/personal care; and biotechnology.



          GLOBAL TECHNOLOGY PORTFOLIO


          Global Technology Portfolio seeks long-term growth of capital. It
          pursues its objective by investing primarily in equity securities of
          U.S. and foreign companies selected for their growth potential.
          Normally, it invests at least 65% of its total assets in securities of
          companies that the portfolio manager believes will benefit
          significantly from advances or improvements in technology. These
          companies generally fall into two categories:



          a. Companies that the portfolio manager believes have or will develop
          products, processes or services that will provide significant
          technological advancements or improvements; and



          b. Companies that the portfolio manager believes rely extensively on
          technology in connection with their operations or services.



The following questions and answers are designed to help you better understand
the Equity Portfolios' principal investment strategies.


1. HOW ARE COMMON STOCKS SELECTED?


          Each of the Portfolios may invest substantially all of its assets in
          common stocks if its portfolio manager believes that common stocks
          will appreciate in value. The portfolio managers generally take a
          "bottom up" approach to selecting companies. In other words, they seek
          to identify individual companies with earnings growth potential that
          may not be recognized by the market at large. They make this
          assessment by looking at companies one at a time, regardless of size,
          country of organization, place of principal business activity, or
          other similar selection criteria. Except for Balanced Portfolio,
          Equity Income Portfolio and Growth and Income Portfolio, realization
          of income is not a significant consideration when choosing investments
          for the Portfolios. Income realized on the Portfolios' investments may
          be incidental to their objectives. In the case of Balanced Portfolio,
          Equity Income Portfolio and Growth and Income Portfolio, a portfolio
          manager may consider dividend-paying characteristics to a greater
          degree in selecting common stock.


2. ARE THE SAME CRITERIA USED TO SELECT FOREIGN SECURITIES?

          Generally, yes. The portfolio managers seek companies that meet their
          selection criteria, regardless of where a company is located. Foreign
          securities are generally selected on a stock-by-stock basis without
          regard to any defined allocation among countries or geographic
          regions. However, certain factors such as expected levels of
          inflation, government policies influencing business conditions, the
          outlook for currency relationships, and prospects for economic growth
          among countries, regions or geographic areas may warrant greater
          consideration in selecting foreign securities. There are no
          limitations on the countries in which the Portfolios may invest and
          the Portfolios may at times have significant foreign exposure.

3. WHAT DOES "MARKET CAPITALIZATION" MEAN?


          Market capitalization is the most commonly used measure of the size
          and value of a company. It is computed by multiplying the current
          market price of a share of the company's stock by the total number of
          its shares outstanding. As noted previously, market capitalization is
          an important investment criteria for Aggressive Growth Portfolio.
          Although the other Equity Portfolios offered by this Prospectus do not
          emphasize companies of any particular size, Portfolios with a larger
          asset base are more likely to invest in larger, more established
          issuers.



4. HOW DO BALANCED PORTFOLIO, EQUITY INCOME PORTFOLIO AND GROWTH AND INCOME
   PORTFOLIO DIFFER FROM EACH OTHER?



          Growth and Income Portfolio places a greater emphasis on aggressive
          growth stocks and may derive a greater portion of its income from
          dividend-paying common stocks. Because of these factors, its NAV can
          be expected to fluctuate more than Balanced Portfolio or Equity Income
          Portfolio. Although Equity Income Portfolio invests substantially all
          of its assets in common stocks, it emphasizes investments in dividend-
          paying common stocks and other equity securities characterized by
          relatively greater price stability, and thus may be expected to be
          less volatile than Growth and Income Portfolio, as discussed in more
          detail below. Balanced Portfolio places a greater emphasis on the
          income component of its portfolio and invests to a greater degree in
          securities selected primarily for their income potential. As a result
          it is expected to be less volatile than Equity Income Portfolio and
          Growth and Income Portfolio.



5. HOW DOES EQUITY INCOME PORTFOLIO TRY TO LIMIT PORTFOLIO VOLATILITY?


          Equity Income Portfolio seeks to provide a lower level of volatility
          than the stock market at large, as measured by the S&P 500. The lower
          volatility sought by this Portfolio is expected to result primarily
          from investments in dividend-paying common stocks and other equity
          securities characterized by relatively greater price stability. The
          greater price stability sought by Equity Income Portfolio may be
          characteristic of companies that generate above average free cash
          flows. A company may use free cash flows for a number of purposes
          including commencing or increasing dividend payments, repurchasing its
          own stock or retiring outstanding debt. The portfolio manager also
          considers growth potential in selecting this Portfolio's securities
          and may hold securities selected solely for their growth potential.


6. HOW ARE ASSETS ALLOCATED BETWEEN THE GROWTH AND INCOME COMPONENTS OF BALANCED
   PORTFOLIO'S AND GROWTH AND INCOME PORTFOLIO'S HOLDINGS?


          Balanced Portfolio and Growth and Income Portfolio shift assets
          between the growth and income components of their holdings based on
          the portfolio managers' analysis of relevant market, financial and
          economic conditions. If a portfolio manager believes that growth
          securities will provide better returns than the yields then available
          or expected on income-producing securities, that Portfolio will place
          a greater emphasis on the growth component.


7. WHAT TYPES OF SECURITIES MAKE UP THE GROWTH COMPONENT OF THE BALANCED
   PORTFOLIO, EQUITY INCOME PORTFOLIO AND GROWTH AND INCOME PORTFOLIO?



          The growth component of these Portfolios is expected to consist
          primarily of common stocks, but may also include warrants, preferred
          stocks or convertible securities selected primarily for their growth
          potential.


            Investment objectives, principal investment strategies and risks  19
<PAGE>


8. WHAT TYPES OF SECURITIES MAKE UP THE INCOME COMPONENT OF BALANCED PORTFOLIO'S
   AND GROWTH AND INCOME PORTFOLIO'S HOLDINGS?



          The income component of Balanced Portfolio and Growth and Income
          Portfolio is expected to consist of securities that the portfolio
          managers believe have income potential. Such securities may include
          equity securities, convertible securities and all types of debt
          securities. Equity securities may be included in the income component
          of a Portfolio if they currently pay dividends or the portfolio
          manager believes they have the potential for either increasing their
          dividends or commencing dividends, if none are currently paid.



9. WHAT DOES "LIFE SCIENCE ORIENTATION" MEAN IN RELATION TO GLOBAL LIFE SCIENCES
   PORTFOLIO?



          Generally speaking, the "life sciences" relate to maintaining or
          improving quality of life. So, for example, companies with a "life
          science orientation" include companies engaged in research,
          development, production or distribution of products or services
          related to health and personal care, medicine or pharmaceuticals. Life
          science oriented companies also include companies that the portfolio
          manager believes have growth potential primarily as a result of
          particular products, technology, patents or other market advantages in
          the life sciences. Life sciences encompass a variety of industries,
          including health care, nutrition, agriculture, medical diagnostics,
          nuclear and biochemical research and development and health care
          facilities ownership and operation.



10. HOW DOES GLOBAL TECHNOLOGY PORTFOLIO'S INDUSTRY POLICY DIFFER FROM THAT OF
    GLOBAL LIFE SCIENCES PORTFOLIO?



          Unlike Global Life Sciences Portfolio, Global Technology Portfolio
          will not concentrate its investments in any particular industry or
          group of related industries. As a result, its portfolio manager may
          have more flexibility to find companies that he believes will benefit
          from advances or improvements in technology in a number of industries.
          Nevertheless, the Portfolio may hold a significant portion of its
          assets in industries such as: aerospace/defense; biotechnology;
          computers; office/business equipment; semi-conductors; software;
          telecommunications; and telecommunications equipment.

FIXED-INCOME PORTFOLIOS

          This section takes a closer look at the investment objectives of each
          of the Fixed-Income Portfolios, their principal investment strategies
          and certain risks of investing in the Fixed-Income Portfolios.
          Strategies and policies that are noted as "fundamental" cannot be
          changed without a shareholder vote.

          Please carefully review the "Risks" section of this Prospectus on
          pages 26-28 for a discussion of risks associated with certain
          investment techniques. We've also included a Glossary with
          descriptions of investment terms used throughout this Prospectus.

INVESTMENT OBJECTIVES AND PRINCIPAL INVESTMENT STRATEGIES

          In addition to considering economic factors such as the effect of
          interest rates on a Portfolio's investments, the portfolio managers
          apply a "bottom up" approach in choosing investments. In other words,
          they look mostly for income-producing securities that meet their
          investment criteria one at a time. If a portfolio manager is unable to
          find such investments, much of a Portfolio's assets may be in cash or
          similar investments.

          FLEXIBLE INCOME PORTFOLIO

          Flexible Income Portfolio seeks to obtain maximum total return,
          consistent with preservation of capital. It pursues its objective by
          primarily investing in a wide variety of income-producing securities
          such as corporate bonds and notes, government securities and preferred
          stock. As a fundamental policy, the Portfolio will invest at least 80%
          of its assets in income-producing securities. The Portfolio may own an
          unlimited amount of high-yield/high-risk bonds, and these may be a big
          part of the portfolio. This Portfolio generates total return from a
          combination of current income and capital appreciation, but income is
          usually the dominant portion.


          HIGH-YIELD PORTFOLIO

          High-Yield Portfolio seeks to obtain high current income. Capital
          appreciation is a secondary objective when consistent with its primary
          objective. It pursues its objectives by normally investing 65% of its
          assets in high-yield/high-risk securities, and may at times invest all
          of its assets in these securities.


The following questions and answers are designed to help you better understand
the Fixed-Income Portfolios' principal investment strategies.

1. HOW DO INTEREST RATES AFFECT THE VALUE OF MY INVESTMENT?

          Generally, a fixed-income security will increase in value when
          interest rates fall and decrease in value when interest rates rise.
          Longer-term securities are generally more sensitive to interest rate
          changes than shorter-term securities, but they generally offer higher
          yields to compensate investors for the associated risks. High-yield
          bond prices are generally less directly responsive to interest rate
          changes than investment grade issues and may not always follow this
          pattern. A bond fund's average-weighted effective maturity and its
          duration are measures of how the fund may react to interest rate
          changes.

2. HOW DO THE FIXED-INCOME PORTFOLIOS MANAGE INTEREST RATE RISK?

          Each Fixed-Income Portfolio may vary the average-weighted effective
          maturity of its assets to reflect its portfolio manager's analysis of
          interest rate trends and other factors. A Portfolio's average-weighted
          effective maturity will tend to be shorter when the portfolio manager
          expects interest rates to rise and longer when its portfolio manager
          expects interest rates to fall. The Portfolios may also use futures,
          options and other derivatives to manage interest rate risks.

3. WHAT IS MEANT BY A PORTFOLIO'S "AVERAGE-WEIGHTED EFFECTIVE MATURITY"?

          The stated maturity of a bond is the date when the issuer must repay
          the bond's entire principal value to an investor. Some types of bonds
          may also have an "effective maturity" that is shorter than the stated
          date due to prepayment or call provisions. Securities without
          prepayment or call provisions generally have an effective maturity
          equal to their stated maturity. Dollar-weighted effective maturity is
          calculated by averaging the effective maturity of bonds held by a
          Portfolio with each effective maturity "weighted" according to the
          percentage of net assets that it represents.

4. WHAT IS MEANT BY A PORTFOLIO'S "DURATION"?

          A bond's duration indicates the time it will take an investor to
          recoup his investment. Unlike average maturity, duration reflects both
          principal and interest payments. Generally, the higher the coupon rate
          on a bond, the lower its duration will be. The duration of a bond
          portfolio is calculated by averaging the duration of bonds held by a
          fund with each duration "weighted" according to the percentage of net
          assets that it represents. Because duration accounts for interest
          payments, a Portfolio's duration is usually shorter than its average
          maturity.


5. WHAT IS A HIGH-YIELD/HIGH-RISK BOND?



          A high-yield/high-risk bond (also called a "junk" bond) is a bond
          rated below investment grade by major rating agencies (i.e., BB or
          lower by Standard & Poor's or Ba or lower by Moody's) or an unrated
          bond of similar quality. It presents greater risk of default (the
          failure to make timely interest and principal payments) than higher
          quality bonds.

GENERAL PORTFOLIO POLICIES OF THE PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO

          Unless otherwise stated, each of the following policies applies to all
          of the Portfolios other than Money Market Portfolio. The percentage
          limitations included in these policies and elsewhere in this
          Prospectus apply at the time of purchase of the security. So, for
          example, if a Portfolio exceeds a limit as a result of market
          fluctuations or the sale of other securities, it will not be required
          to dispose of any securities.

          CASH POSITION
          When a portfolio manager believes that market conditions are
          unfavorable for profitable investing, or when he or she is otherwise
          unable to locate attractive investment opportunities, the Portfolios'
          cash or similar investments may increase. In other words, the
          Portfolios do not always stay fully invested in stocks and bonds. Cash
          or similar investments generally are a residual - they represent the
          assets that remain after a portfolio manager has committed available
          assets to desirable investment opportunities. However, a portfolio
          manager may also temporarily increase a Portfolio's cash position to
          protect its assets or maintain liquidity. Partly because the portfolio
          managers act independently of each other, the cash positions of the
          Portfolios may vary significantly.

          When a Portfolio's investments in cash or similar investments
          increase, it may not participate in market advances or declines to the
          same extent that it would if the Portfolio remained more fully
          invested in stocks or bonds.

          OTHER TYPES OF INVESTMENTS

          The Equity Portfolios invest primarily in domestic and foreign equity
          securities, which may include preferred stocks, common stocks,
          warrants and securities convertible into common or preferred stocks.
          The Equity Portfolios also invest in domestic and foreign equity
          securities with varying degrees of emphasis on income. The Portfolios
          may also invest to a lesser degree in other types of securities. These
          securities (which are described in the Glossary) may include:


          - debt securities


          - indexed/structured securities



          - high-yield/high-risk bonds (less than 35% of each Portfolio's
            assets)



          - options, futures, forwards, swaps and other types of derivatives for
            hedging purposes or for non-hedging purposes such as seeking to
            enhance return


          - securities purchased on a when-issued, delayed delivery or forward
            commitment basis

          The Fixed-Income Portfolios invest primarily in fixed-income
          securities which may include corporate bonds and notes, government
          securities, preferred stock, high-yield/high-risk fixed-income
          securities and municipal obligations. The Portfolios may also invest
          to a lesser degree in other types of securities. These securities
          (which are described in the Glossary) may include:

          - common stocks

          - mortgage- and asset-backed securities

          - zero coupon, pay-in-kind and step coupon securities


          - options, futures, forwards, swaps and other types of derivatives for
            hedging purposes or for non-hedging purposes such as seeking to
            enhance return


          - securities purchased on a when-issued, delayed delivery or forward
            commitment basis

<PAGE>

          ILLIQUID INVESTMENTS
          Each Portfolio may invest up to 15% of its net assets in illiquid
          investments. An illiquid investment is a security or other position
          that cannot be disposed of quickly in the normal course of business.
          For example, some securities are not registered under U.S. securities
          laws and cannot be sold to the U.S. public because of SEC regulations
          (these are known as "restricted securities"). Under procedures adopted
          by the Portfolios' Trustees, certain restricted securities may be
          deemed liquid, and will not be counted toward this 15% limit.

          FOREIGN SECURITIES
          The Portfolios may invest without limit in foreign equity and debt
          securities. The Portfolios may invest directly in foreign securities
          denominated in a foreign currency and not publicly traded in the
          United States. Other ways of investing in foreign securities include
          depositary receipts or shares, and passive foreign investment
          companies.

          SPECIAL SITUATIONS
          Each Portfolio may invest in special situations. A special situation
          arises when, in the opinion of a Portfolio's manager, the securities
          of a particular issuer will be recognized and appreciate in value due
          to a specific development with respect to that issuer. Developments
          creating a special situation might include, among others, a new
          product or process, a technological breakthrough, a management change
          or other extraordinary corporate event, or differences in market
          supply of and demand for the security. A Portfolio's performance could
          suffer if the anticipated development in a "special situation"
          investment does not occur or does not attract the expected attention.

          PORTFOLIO TURNOVER
          The Portfolios generally intend to purchase securities for long-term
          investment although, to a limited extent, a Portfolio may purchase
          securities in anticipation of relatively short-term price gains.
          Short-term transactions may also result from liquidity needs,
          securities having reached a price or yield objective, changes in
          interest rates or the credit standing of an issuer, or by reason of
          economic or other developments not foreseen at the time of the
          investment decision. A Portfolio may also sell one security and
          simultaneously purchase the same or a comparable security to take
          advantage of short-term differentials in bond yields or securities
          prices. Changes are made in a Portfolio's holdings whenever its
          portfolio manager believes such changes are desirable. Portfolio
          turnover rates are generally not a factor in making buy and sell
          decisions.


          Global Technology Portfolio may invest in companies with relatively
          short product cycles, for example, 6 to 9 months. Consequently its
          portfolio turnover may be more frequent. Increased portfolio turnover
          may result in higher costs for brokerage commissions, dealer mark-ups
          and other transaction costs and may also result in taxable capital
          gains. Higher costs associated with increased portfolio turnover may
          offset gains in a Portfolio's performance.

RISKS FOR EQUITY PORTFOLIOS



          Because the Portfolios may invest substantially all of their assets in
          common stocks, the main risk is the risk that the value of the stocks
          they hold might decrease in response to the activities of an
          individual company or in response to general market and/or economic
          conditions. If this occurs, a Portfolio's share price may also
          decrease. A Portfolio's performance may also be affected by risks
          specific to certain types of investments, such as foreign securities,
          derivative investments, non-investment grade debt securities, initial
          public offerings (IPOs) or companies with relatively small market
          capitalizations. IPOs and other investment techniques may have a
          magnified performance impact on a portfolio with a small asset base. A
          portfolio may not experience similar performance as its assets grow.
          Global Technology Portfolio's performance may also be affected by
          industry risk.



The following questions and answers are designed to help you better understand
some of the risks of investing in the Equity Portfolios.


1. THE PORTFOLIOS MAY INVEST IN SMALLER OR NEWER COMPANIES. DOES THIS CREATE ANY
   SPECIAL RISKS?


          Many attractive investment opportunities may be smaller, start-up
          companies offering emerging products or services. Smaller or newer
          companies may suffer more significant losses as well as realize more
          substantial growth than larger or more established issuers because
          they may lack depth of management, be unable to generate funds
          necessary for growth or potential development, or be developing or
          marketing new products or services for which markets are not yet
          established and may never become established. In addition, such
          companies may be insignificant factors in their industries and may
          become subject to intense competition from larger or more established
          companies. Securities of smaller or newer companies may have more
          limited trading markets than the markets for securities of larger or
          more established issuers, and may be subject to wide price
          fluctuations. Investments in such companies tend to be more volatile
          and somewhat more speculative.



2. HOW DOES THE NONDIVERSIFIED STATUS OF AGGRESSIVE GROWTH PORTFOLIO, GLOBAL
   LIFE SCIENCES PORTFOLIO AND GLOBAL TECHNOLOGY PORTFOLIO AND CAPITAL
   APPRECIATION PORTFOLIO AFFECT THEIR RISK?


          Diversification is a way to reduce risk by investing in a broad range
          of stocks or other securities. A "nondiversified" portfolio has the
          ability to take larger positions in a smaller number of issuers.
          Because the appreciation or depreciation of a single stock may have a
          greater impact on the NAV of a nondiversified portfolio, its share
          price can be expected to fluctuate more than a comparable diversified
          portfolio. This fluctuation, if significant, may affect the
          performance of a Portfolio.

RISKS FOR FIXED-INCOME PORTFOLIOS


          Because the Portfolios invest substantially all of their assets in
          fixed-income securities, they are subject to risks such as credit or
          default risks, and decreased value due to interest rate increases. A
          Portfolio's performance may also be affected by risks to certain types
          of investments, such as foreign securities, derivative instruments and
          initial public offerings (IPOs). IPOs and other investment techniques
          may have a magnified performance impact on a portfolio with a small
          asset base. A portfolio may not experience similar performance as its
          assets grow.


The following questions and answers are designed to help you better understand
some of the risks of investing in the Fixed-Income Portfolios.

1. HOW DO THE FIXED-INCOME PORTFOLIOS DIFFER FROM EACH OTHER IN TERMS OF PRIMARY
   INVESTMENT TYPE, CREDIT RISK AND INTEREST RATE RISK?

          Flexible Income Portfolio and High-Yield Portfolio invest primarily in
          corporate bonds. High-Yield Portfolio's credit risk is generally
          higher than Flexible Income Portfolio. Flexible Income Portfolio's
          interest rate risk is generally higher than High-Yield Portfolio.

2. WHAT IS MEANT BY "CREDIT QUALITY" AND WHAT ARE THE RISKS ASSOCIATED WITH IT?

          Credit quality measures the likelihood that the issuer will meet its
          obligations on a bond. One of the fundamental risks associated with
          all fixed-income funds is credit risk, which is the risk that an
          issuer will be unable to make principal and interest payments when
          due. U.S. government securities are generally considered to be the
          safest type of investment in terms of credit risk. Municipal
          obligations generally rank between U.S. government securities and
          corporate debt securities in terms of credit safety. Corporate debt
          securities, particularly those rated below investment grade, present
          the highest credit risk.

3. HOW IS CREDIT QUALITY MEASURED?


          Ratings published by nationally recognized statistical rating agencies
          such as Standard & Poor's Ratings Service and Moody's Investors
          Service, Inc. are widely accepted measures of credit risk. The lower a
          bond issue is rated by an agency, the more credit risk it is
          considered to represent. Lower rated bonds generally pay higher yields
          to compensate investors for the associated risk. Please refer to
          "Explanation of Rating Categories" on pages 48-49 for a description of
          rating categories.


RISKS COMMON TO ALL NON-MONEY MARKET PORTFOLIOS

The following questions and answers discuss risks that apply to all Portfolios
other than Money Market Portfolio.

1. HOW COULD THE PORTFOLIOS' INVESTMENTS IN FOREIGN SECURITIES AFFECT THEIR
   PERFORMANCE?

          The Portfolios may invest without limit in foreign securities either
          indirectly (e.g., depositary receipts) or directly in foreign markets.
          Investments in foreign securities, including those of foreign
          governments, may involve greater risks than investing in domestic
          securities because the Portfolios' performance may depend on issues
          other than the performance of a particular company. These issues
          include:

          - CURRENCY RISK. As long as a Portfolio holds a foreign security, its
            value will be affected by the value of the local currency relative
            to the U.S. dollar. When a Portfolio sells a foreign denominated
            security, its value may be worth less in U.S. dollars even if the
            security increases in value in its home country. U.S. dollar
            denominated securities of foreign issuers may also be affected by
            currency risk.

          - POLITICAL AND ECONOMIC RISK. Foreign investments may be subject to
            heightened political and economic risks, particularly in emerging
            markets which may have relatively unstable governments, immature

 26 Janus Aspen Series
<PAGE>

            economic structures, national policies restricting investments by
            foreigners, different legal systems, and economies based on only a
            few industries. In some countries, there is the risk that the
            government may take over the assets or operations of a company or
            that the government may impose taxes or limits on the removal of a
            Portfolio's assets from that country.

          - REGULATORY RISK. There may be less government supervision of foreign
            markets. As a result, foreign issuers may not be subject to the
            uniform accounting, auditing and financial reporting standards and
            practices applicable to domestic issuers and there may be less
            publicly available information about foreign issuers.

          - MARKET RISK. Foreign securities markets, particularly those of
            emerging market countries, may be less liquid and more volatile than
            domestic markets. Certain markets may require payment for securities
            before delivery and delays may be encountered in settling securities
            transactions. In some foreign markets, there may not be protection
            against failure by other parties to complete transactions.

          - TRANSACTION COSTS. Costs of buying, selling and holding foreign
            securities, including brokerage, tax and custody costs, may be
            higher than those involved in domestic transactions.


2. ARE THERE SPECIAL RISKS ASSOCIATED WITH INVESTMENTS IN HIGH-YIELD/HIGH-RISK
   BONDS?



          High-yield/high-risk bonds (or "junk" bonds) are bonds rated below
          investment grade by the primary rating agencies such as Standard &
          Poor's and Moody's. The value of lower quality bonds generally is more
          dependent on credit risk, or the ability of the issuer to meet
          interest and principal payments, than investment grade debt bonds.
          Issuers of high-yield bonds may not be as strong financially as those
          issuing bonds with higher credit ratings and are more vulnerable to
          real or perceived economic changes, political changes or adverse
          developments specific to the issuer.



          The junk bond market can experience sudden and sharp price swings.
          Because Flexible Income Portfolio and High-Yield Portfolio may invest
          a significant portion of their assets in high-yield/high-risk bonds,
          investors should be willing to tolerate a corresponding increase in
          the risk of significant and sudden changes in NAV.



          Please refer to "Explanation of Rating Categories" on pages 48-49 for
          a description of bond rating categories.


3. HOW DO THE PORTFOLIOS TRY TO REDUCE RISK?


          The Portfolios may use futures, options, swaps and other derivative
          instruments to "hedge" or protect their portfolios from adverse
          movements in securities prices and interest rates. The Portfolios may
          also use a variety of currency hedging techniques, including forward
          currency contracts, to manage exchange rate risk. The portfolio
          managers believe the use of these instruments will benefit the
          Portfolios. However, a Portfolio's performance could be worse than if
          the Portfolio had not used such instruments if a portfolio manager's
          judgement proves incorrect. Risks associated with the use of
          derivative instruments are described in the SAI.



4. WHAT IS "INDUSTRY RISK"?



          Industry risk is the possibility that a group of related stocks will
          decline in price due to industry-specific developments. Companies in
          the same or similar industries may share common characteristics and
          are more likely to react similarly to industry-specific market or
          economic developments. In the life sciences, for example, many
          companies are subject to government regulation and approval of their
          products and services, which may affect their price or availability.
          In addition, the products and services offered by these


            Investment objectives, principal investment strategies and risks  27
<PAGE>


          companies may quickly become obsolete in the face of scientific or
          technological developments. The economic outlook of such companies may
          fluctuate dramatically due to changes in regulatory or competitive
          environments. In technology-related industries, competitive pressures
          may have a significant effect on the performance of companies in which
          Global Technology Portfolio may invest. In addition, technology and
          technology-related companies often progress at an accelerated rate,
          and these companies may be subject to short product cycles and
          aggressive pricing which may increase their volatility.



          Global Life Sciences Portfolio invests in a concentrated portfolio,
          which may result in greater exposure to related industries. As a
          result, the Portfolio may be more volatile than a less concentrated
          portfolio. Although Global Technology Portfolio does not "concentrate"
          in a specific group of industries, it may, at times, have significant
          exposure to companies in a variety of technology-related industries.

MONEY MARKET PORTFOLIO

          This section takes a closer look at the investment objective of Money
          Market Portfolio, its principal investment strategies and certain
          risks of investing in the Portfolio. Strategies and policies that are
          noted as "fundamental" cannot be changed without a shareholder vote.

          Money Market Portfolio is subject to certain specific SEC rule
          requirements. Among other things, the Portfolio is limited to
          investing in U.S. dollar-denominated instruments with a remaining
          maturity of 397 days or less (as calculated pursuant to Rule 2a-7
          under the 1940 Act).

INVESTMENT OBJECTIVE AND PRINCIPAL INVESTMENT STRATEGIES

          Money Market Portfolio seeks maximum current income to the extent
          consistent with stability of capital. It pursues its objective by
          investing primarily in high quality debt obligations and obligations
          of financial institutions. Debt obligations may include commercial
          paper, notes and bonds, and variable amount master demand notes.
          Obligations of financial institutions include certificates of deposit
          and time deposits.

          Money Market Portfolio will:

          - invest in high quality, short-term money market instruments that
            present minimal credit risks, as determined by Janus Capital

          - invest only in U.S. dollar-denominated instruments that have a
            remaining maturity of 397 days or less (as calculated pursuant to
            Rule 2a-7 under the 1940 Act)

          - maintain a dollar-weighted average portfolio maturity of 90 days or
            less

TYPES OF INVESTMENTS

          Money Market Portfolio invests primarily in:

          - high quality debt obligations

          - obligations of financial institutions

          The Portfolio may also invest (to a lesser degree) in:

          - U.S. Government Securities (securities issued or guaranteed by the
            U.S. government, its agencies and instrumentalities)

          - municipal securities

          DEBT OBLIGATIONS


          The Portfolio may invest in U.S. dollar denominated debt obligations.
          Debt obligations include:


          - commercial paper

          - notes and bonds

          - variable amount master demand notes (the payment obligations on
            these instruments may be backed by securities, swap agreements or
            other assets, by a guarantee of a third party or solely by the
            unsecured promise of the issuer to make payments when due)

          - privately issued commercial paper or other securities that are
            restricted as to disposition under the federal securities laws

            Investment objectives, principal investment strategies and risks  29
<PAGE>

          OBLIGATIONS OF FINANCIAL INSTITUTIONS

          Examples of obligations of financial institutions include:

          - negotiable certificates of deposit, bankers' acceptances, time
            deposits and other obligations of U.S. banks (including savings and
            loan associations) having total assets in excess of one billion
            dollars and U.S. branches of foreign banks having total assets in
            excess of ten billion dollars

          - Eurodollar and Yankee bank obligations (Eurodollar bank obligations
            are dollar-denominated certificates of deposit or time deposits
            issued outside the U.S. capital markets by foreign branches of U.S.
            banks and by foreign banks. Yankee bank obligations are
            dollar-denominated obligations issued in the U.S. capital markets by
            foreign banks)

          - other U.S. dollar-denominated obligations of foreign banks having
            total assets in excess of ten billion dollars that Janus Capital
            believes are of an investment quality comparable to obligations of
            U.S. banks in which the Portfolio may invest

          Foreign, Eurodollar (and to a limited extent, Yankee) bank obligations
          are subject to certain sovereign risks. One such risk is the
          possibility that a foreign government might prevent dollar-denominated
          funds from flowing across its borders. Other risks include: adverse
          political and economic developments in a foreign country; the extent
          and quality of government regulation of financial markets and
          institutions; the imposition of foreign withholding taxes; and
          expropriation or nationalization of foreign issuers.

INVESTMENT TECHNIQUES

          The following is a description of other investment techniques that
          Money Market Portfolio may use:

          PARTICIPATION INTERESTS
          A participation interest gives Money Market Portfolio a proportionate,
          undivided interest in underlying debt securities and sometimes carries
          a demand feature.

          DEMAND FEATURES
          Demand features give Money Market Portfolio the right to resell
          securities at specified periods prior to their maturity dates. Demand
          features may shorten the life of a variable or floating rate security,
          enhance the instrument's credit quality and provide a source of
          liquidity.

          Demand features are often issued by third party financial
          institutions, generally domestic and foreign banks. Accordingly, the
          credit quality and liquidity of Money Market Portfolio's investments
          may be dependent in part on the credit quality of the banks supporting
          Money Market Portfolio's investments. This will result in exposure to
          risks pertaining to the banking industry, including the foreign
          banking industry. Brokerage firms and insurance companies also provide
          certain liquidity and credit support.

          VARIABLE AND FLOATING RATE SECURITIES
          Money Market Portfolio may invest in securities which have variable or
          floating rates of interest. These securities pay interest at rates
          that are adjusted periodically according to a specified formula,
          usually with reference to an interest rate index or market interest
          rate. Variable and floating rate securities are subject to changes in
          value based on changes in market interest rates or changes in the
          issuer's or guarantor's creditworthiness.

          MORTGAGE- AND ASSET-BACKED SECURITIES
          Money Market Portfolio may purchase fixed or variable rate
          mortgage-backed securities issued by the Government National Mortgage
          Association, Federal National Mortgage Association, the Federal Home
          Loan Mortgage Corporation, or other governmental or government-related
          entity. The Portfolio may purchase other mortgage- and asset-backed
          securities including securities backed by automobile loans, equipment
          leases or credit card receivables.

          Unlike traditional debt instruments, payments on these securities
          include both interest and a partial payment of principal. Prepayments
          of the principal of underlying loans may shorten the effective
          maturities of these securities and may result in the Portfolio having
          to reinvest proceeds at a lower interest rate.

          REPURCHASE AGREEMENTS
          Money Market Portfolio may enter into collateralized repurchase
          agreements. Repurchase agreements are transactions in which the
          Portfolio purchases securities and simultaneously commits to resell
          those securities to the seller at an agreed-upon price on an
          agreed-upon future date. The repurchase price reflects a market rate
          of interest and is collateralized by cash or securities.

          If the seller of the securities underlying a repurchase agreement
          fails to pay the agreed resale price on the agreed delivery date,
          Money Market Portfolio may incur costs in disposing of the collateral
          and may experience losses if there is any delay in its ability to do
          so.

          which, the Service Shares, are offered pursuant to this prospectus.
          The Shares offered by this prospectus are available only in connection
          with investment in and payments under variable insurance contracts as
          well as certain qualified retirement plans that require a fee from
          Portfolio assets to procure distribution and administrative services
          to contract owners and plan participants. Institutional Shares of each
          Portfolio are available only in connection with investment in and
          payments under variable insurance contracts, as well as certain
          qualified retirement plans. Retirement Shares of certain Portfolios
          are offered only to qualified plans using plan service providers that
          are compensated for providing distribution and/or record keeping and
          other administrative services provided to plan participants. Because
          the expenses of each class may differ, the performance of each class
          is expected to differ. If you would like additional information about
          either the Institutional Shares or the Retirement Shares, please call
          1-800-525-0020.



          During the third quarter of 2000, the Retirement Shares shareholders
          will be asked to approve the spin-off of the Retirement Shares into a
          separate Delaware business trust, Janus Adviser Series. In connection
          with this spin-off, each Portfolio will distribute all of its ordinary
          income and capital gain income earned through the date of the
          spin-off. The distributions will be made for all classes, including
          Service Shares. It is anticipated that the spin-off and distributions
          will occur during the third quarter of 2000.


          DISTRIBUTION FEE

          Under a distribution and service plan adopted in accordance with Rule
          12b-1 under the 1940 Act, the Shares may pay Janus Distributors, Inc.,
          the Trust's distributor, a fee at an annual rate of up to 0.25% of the
          average daily net assets of the Shares of a Portfolio. Under the terms
          of the Plan, the Trust is authorized to make payments to Janus
          Distributors for remittance to insurance companies and qualified plan
          service providers as compensation for distribution and shareholder
          servicing performed by such entities. Because 12b-1 fees are paid out
          of the Service Shares' assets on an ongoing basis, they will increase
          the cost of your investment and may cost you more than paying other
          types of sales charges.

          CONFLICTS OF INTEREST

          The Trust's shares are available only to variable annuity and variable
          life separate accounts of insurance companies that are unaffiliated
          with Janus Capital and to certain qualified retirement plans. Although
          the Portfolios do not currently anticipate any disadvantages to owners
          of variable insurance contracts because each Portfolio offers its
          shares to such entities, there is a possibility that a material
          conflict may arise. The Trustees monitor events in order to identify
          any disadvantages or material irreconcilable conflicts and to
          determine what action, if any, should be taken in response. If a
          material disadvantage or conflict occurs, the Trustees may require one
          or more insurance company separate accounts or qualified plans to
          withdraw its investments in one or more Portfolios or substitute
          Shares of another Portfolio. If this occurs, a Portfolio may be forced
          to sell its securities at disadvantageous prices. In addition, the
          Trustees may refuse to sell Shares of any Portfolio to any separate
          account or qualified plan or may suspend or terminate the offering of
          a Portfolio's Shares if such action is required by law or regulatory
          authority or is in the best interests of that Portfolio's
          shareholders. It is possible that a qualified plan investing in the
          Portfolios could lose its qualified plan status under the Internal
          Revenue Code, which could have adverse tax consequences on insurance
          company separate accounts investing in the Shares. Janus Capital
          intends to monitor such qualified plans and the Portfolios may
          discontinue sales to a qualified plan and require plan participants
          with existing investments in the Shares to redeem those investments if
          a plan loses (or in the opinion of Janus Capital is at risk of losing)
          its qualified plan status.

Distributions and taxes

DISTRIBUTIONS

          To avoid taxation of the Portfolios, the Internal Revenue Code
          requires each Portfolio to distribute net income and any net gains
          realized on its investments annually. A Portfolio's income from
          dividends and interest and any net realized short-term gains are paid
          to shareholders as ordinary income dividends. Net realized long-term
          gains are paid to shareholders as capital gains distributions.

PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO

          Each class of each Portfolio, other than Money Market Portfolio,
          distributes substantially all of its investment income at least
          semi-annually and its net realized gains, if any, at least annually.
          All dividends and capital gains distributions from Shares of a
          Portfolio will automatically be reinvested into additional Shares of
          that Portfolio.

          HOW DISTRIBUTIONS AFFECT NAV

          Distributions, other than daily income dividends, are paid to
          shareholders as of the record date of the distribution of a Portfolio,
          regardless of how long the shares have been held. Undistributed income
          and realized gains are included in the daily NAV of a Portfolio's
          Shares. The Share price of a Portfolio drops by the amount of the
          distribution, net of any subsequent market fluctuations. For example,
          assume that on December 31, the Shares of Growth Portfolio declared a
          dividend in the amount of $0.25 per share. If the price of Growth
          Portfolio's Shares was $10.00 on December 30, the share price on
          December 31 would be $9.75, barring market fluctuations.

MONEY MARKET PORTFOLIO

          For the Shares of Money Market Portfolio, dividends representing
          substantially all of the net investment income and any net realized
          gains on sales of securities are declared daily, Saturdays, Sundays
          and holidays included, and distributed on the last business day of
          each month. If a month begins on a Saturday, Sunday or holiday,
          dividends for those days are declared at the end of the preceding
          month and distributed on the first business day of the month. All
          distributions will be automatically reinvested in Shares of the
          Portfolio.

TAXES

          TAXES ON DISTRIBUTIONS

          Because Shares of the Portfolios may be purchased only through
          variable insurance contracts and qualified plans, it is anticipated
          that any income dividends or capital gains distributions made by the
          Shares of a Portfolio will be exempt from current taxation if left to
          accumulate within the variable insurance contract or qualified plan.
          Generally, withdrawals from such contracts or plans may be subject to
          ordinary income tax and, if made before age 59 1/2, a 10% penalty tax.
          The tax status of your investment depends on the features of your
          qualified plan or variable insurance contract. Further information may
          be found in your plan documents or in the prospectus of the separate
          account offering such contract.

          TAXATION OF THE PORTFOLIOS


          Dividends, interest and some gains received by the Portfolios on
          foreign securities may be subject to tax withholding or other foreign
          taxes. The Portfolios may from year to year make the election
          permitted under Section 853 of the Internal Revenue Code to pass
          through such taxes to shareholders as a foreign tax credit. If such
          election is not made, any foreign taxes paid or accrued will represent
          an expense to the Portfolios which will reduce their investment
          income.


 40 Janus Aspen Series
<PAGE>


          The Portfolios do not expect to pay any federal income or excise taxes
          because they intend to meet certain requirements of the Internal
          Revenue Code. In addition, because a class of shares of each Portfolio
          are sold in connection with variable insurance contracts, each
          Portfolio intends to qualify under the Internal Revenue Code with
          respect to the diversification requirements related to the
          tax-deferred status of insurance company separate accounts.

Shareholder's guide

          INVESTORS MAY NOT PURCHASE OR REDEEM SHARES OF THE PORTFOLIOS
          DIRECTLY. SHARES MAY BE PURCHASED OR REDEEMED ONLY THROUGH VARIABLE
          INSURANCE CONTRACTS OFFERED BY THE SEPARATE ACCOUNTS OF PARTICIPATING
          INSURANCE COMPANIES OR THROUGH QUALIFIED RETIREMENT PLANS. CERTAIN
          PORTFOLIOS MAY NOT BE AVAILABLE IN CONNECTION WITH A PARTICULAR
          CONTRACT AND CERTAIN CONTRACTS MAY LIMIT ALLOCATIONS AMONG THE
          PORTFOLIOS. REFER TO THE PROSPECTUS FOR THE PARTICIPATING INSURANCE
          COMPANY'S SEPARATE ACCOUNT OR YOUR PLAN DOCUMENTS FOR INSTRUCTIONS ON
          PURCHASING OR SELLING OF VARIABLE INSURANCE CONTRACTS AND ON HOW TO
          SELECT SPECIFIC PORTFOLIOS AS INVESTMENT OPTIONS FOR A CONTRACT OR A
          QUALIFIED PLAN.

PRICING OF PORTFOLIO SHARES

          Investments will be processed at the NAV next determined after an
          order is received and accepted by a Portfolio or its agent. In order
          to receive a day's price, your order must be received by the close of
          the regular trading session of the New York Stock Exchange any day
          that the NYSE is open. Securities of the Portfolios other than Money
          Market Portfolio are valued at market value or, if a market quotation
          is not readily available, at their fair value determined in good faith
          under procedures established by and under the supervision of the
          Trustees. Short-term instruments maturing within 60 days are valued at
          amortized cost, which approximates market value. See the SAI for more
          detailed information.

          To the extent a Portfolio holds securities that are primarily listed
          on foreign exchanges that trade on weekends or other days when the
          Portfolios do not price their shares, the NAV of a Portfolio's shares
          may change on days when shareholders will not be able to purchase or
          redeem the Portfolio's shares.

          Money Market Portfolio's securities are valued at their amortized
          cost. Amortized cost valuation involves valuing an instrument at its
          cost and thereafter assuming a constant amortization to maturity (or
          such other date as permitted by Rule 2a-7) of any discount or premium.
          If fluctuating interest rates cause the market value of the portfolio
          to deviate more than 1/2 of 1% from the value determined on the basis
          of amortized cost, the Trustees will consider whether any action, such
          as adjusting the Share's NAV to reflect current market conditions,
          should be initiated to prevent any material dilutive effect on
          shareholders.

PURCHASES

          Purchases of Shares may be made only by the separate accounts of
          insurance companies for the purpose of funding variable insurance
          contracts or by qualified plans. Refer to the prospectus of the
          appropriate insurance company separate account or your plan documents
          for information on how to invest in the Shares of each Portfolio.
          Participating insurance companies and certain other designated
          organizations are authorized to receive purchase orders on the
          Portfolios' behalf.


          The Portfolios do not permit frequent trading or market timing.
          Excessive purchases of Portfolio Shares disrupt portfolio management
          and drive Portfolio expenses higher. Each Portfolio reserves the right
          to reject any specific purchase order. Purchase orders may be refused
          if, in Janus Capital's opinion, they are of a size that would disrupt
          the management of a Portfolio. Although there is no present intention
          to do so, the Portfolios may discontinue sales of their shares if
          management and the Trustees believe that continued sales may adversely
          affect a Portfolio's ability to achieve its investment objective. If
          sales of a Portfolio's Shares are discontinued, it is expected that
          existing participants invested in that Portfolio would be permitted to
          continue to authorize investment in that Portfolio and to reinvest any
          dividends or capital gains distributions, absent highly unusual
          circumstances. The Portfolios may discontinue sales to a qualified
          plan and require plan participants with existing investments in the
          Shares to redeem those


 42 Janus Aspen Series
<PAGE>

          investments if the plan loses (or in the opinion of Janus Capital, is
          at risk of losing) its qualified plan status.

REDEMPTIONS

          Redemptions, like purchases, may be effected only through the separate
          accounts of participating insurance companies or through qualified
          plans. Please refer to the appropriate separate account prospectus or
          plan documents for details.

          Shares of any Portfolio may be redeemed on any business day.
          Redemptions are processed at the NAV next calculated after receipt and
          acceptance of the redemption order by the Portfolio or its agent.
          Redemption proceeds will normally be wired the business day following
          receipt of the redemption order, but in no event later than seven days
          after receipt of such order.


FREQUENT TRADING



          Frequent trading of Portfolio shares in response in short-term
          fluctuations in the market -- also known as "market timing" -- may
          make it very difficult to manage a Portfolio's investments. The
          Portfolios do not permit frequent trading or market timing. When
          market timing occurs, a Portfolio may have to sell portfolio
          securities to have the cash necessary to redeem the market timer's
          shares. This can happen at a time when it is not advantageous to sell
          any securities, which may harm a Portfolio's performance. When large
          dollar amounts are involved, market timing can also make it difficult
          to use long-term investment strategies because the portfolio manager
          cannot predict how much cash a Portfolio will have to invest. When in
          Janus Capital's opinion such activity would have a disruptive effect
          on portfolio management, a Portfolio reserves the right to refuse
          purchase orders and exchanges into a Portfolio by any person, group or
          commonly controlled account. A Portfolio may notify a market timer of
          rejection of a purchase or exchange order after the day the order is
          placed. If a Portfolio allows a market timer to trade Portfolio
          shares, it may require the market timer to enter into a written
          agreement to follow certain procedures and limitations.


SHAREHOLDER COMMUNICATIONS

          Shareholders will receive annual and semiannual reports including the
          financial statements of the Shares of the Portfolios that they have
          authorized for investment. Each report will show the investments owned
          by each Portfolio and the market values thereof, as well as other
          information about the Portfolios and their operations. The Trust's
          fiscal year ends December 31.

                                                    Glossary of investment terms

          This glossary provides a more detailed description of some of the
          types of securities and other instruments in which the Portfolios may
          invest. The Portfolios may invest in these instruments to the extent
          permitted by their investment objectives and policies. The Portfolios
          are not limited by this discussion and may invest in any other types
          of instruments not precluded by the policies discussed elsewhere in
          this Prospectus. Please refer to the SAI for a more detailed
          discussion of certain instruments.

I. EQUITY AND DEBT SECURITIES

          BONDS are debt securities issued by a company, municipality,
          government or government agency. The issuer of a bond is required to
          pay the holder the amount of the loan (or par value of the bond) at a
          specified maturity and to make scheduled interest payments.

          COMMERCIAL PAPER is a short-term debt obligation with a maturity
          ranging from 1 to 270 days issued by banks, corporations and other
          borrowers to investors seeking to invest idle cash. The Portfolios may
          purchase commercial paper issued in private placements under Section
          4(2) of the Securities Act of 1933.

          COMMON STOCKS are equity securities representing shares of ownership
          in a company and usually carry voting rights and earns dividends.
          Unlike preferred stock, dividends on common stock are not fixed but
          are declared at the discretion of the issuer's board of directors.

          CONVERTIBLE SECURITIES are preferred stocks or bonds that pay a fixed
          dividend or interest payment and are convertible into common stock at
          a specified price or conversion ratio.

          DEBT SECURITIES are securities representing money borrowed that must
          be repaid at a later date. Such securities have specific maturities
          and usually a specific rate of interest or an original purchase
          discount.

          DEPOSITARY RECEIPTS are receipts for shares of a foreign-based
          corporation that entitle the holder to dividends and capital gains on
          the underlying security. Receipts include those issued by domestic
          banks (American Depositary Receipts), foreign banks (Global or
          European Depositary Receipts) and broker-dealers (depositary shares).

          FIXED-INCOME SECURITIES are securities that pay a specified rate of
          return. The term generally includes short-and long-term government,
          corporate and municipal obligations that pay a specified rate of
          interest or coupons for a specified period of time, and preferred
          stock, which pays fixed dividends. Coupon and dividend rates may be
          fixed for the life of the issue or, in the case of adjustable and
          floating rate securities, for a shorter period.


          HIGH-YIELD/HIGH-RISK BONDS are bonds that are rated below investment
          grade by the primary rating agencies (e.g., BB or lower by Standard &
          Poor's and Ba or lower by Moody's). Other terms commonly used to
          describe such bonds include "lower rated bonds," "noninvestment grade
          bonds" and "junk bonds."


          MORTGAGE- AND ASSET-BACKED SECURITIES are shares in a pool of
          mortgages or other debt. These securities are generally pass-through
          securities, which means that principal and interest payments on the
          underlying securities (less servicing fees) are passed through to
          shareholders on a pro rata basis. These securities involve prepayment
          risk, which is the risk that the underlying mortgages or other debt
          may be refinanced or paid off prior to their maturities during periods
          of declining interest rates. In that case, a portfolio manager may
          have to reinvest the proceeds from the securities at a lower rate.
          Potential market gains on a security subject to prepayment risk may be
          more limited than potential market gains on a comparable security that
          is not subject to prepayment risk.

          PASSIVE FOREIGN INVESTMENT COMPANIES (PFICS) are any foreign
          corporations which generate certain amounts of passive income or hold
          certain amounts of assets for the production of passive income.
          Passive income includes dividends, interest, royalties, rents and
          annuities. To avoid taxes and interest that the

                                                Glossary of investment terms  45
<PAGE>

          Portfolios must pay if these investments are profitable, the
          Portfolios may make various elections permitted by the tax laws. These
          elections could require that the Portfolios recognize taxable income,
          which in turn must be distributed, before the securities are sold and
          before cash is received to pay the distributions.

          PAY-IN-KIND BONDS are debt securities that normally give the issuer an
          option to pay cash at a coupon payment date or give the holder of the
          security a similar bond with the same coupon rate and a face value
          equal to the amount of the coupon payment that would have been made.

          PREFERRED STOCKS are equity securities that generally pay dividends at
          a specified rate and have preference over common stock in the payment
          of dividends and liquidation. Preferred stock generally does not carry
          voting rights.

          REPURCHASE AGREEMENTS involve the purchase of a security by a
          Portfolio and a simultaneous agreement by the seller (generally a bank
          or dealer) to repurchase the security from the Portfolio at a
          specified date or upon demand. This technique offers a method of
          earning income on idle cash. These securities involve the risk that
          the seller will fail to repurchase the security, as agreed. In that
          case, a Portfolio will bear the risk of market value fluctuations
          until the security can be sold and may encounter delays and incur
          costs in liquidating the security.

          REVERSE REPURCHASE AGREEMENTS involve the sale of a security by a
          Portfolio to another party (generally a bank or dealer) in return for
          cash and an agreement by the Portfolio to buy the security back at a
          specified price and time. This technique will be used primarily to
          provide cash to satisfy unusually high redemption requests, or for
          other temporary or emergency purposes.

          RULE 144A SECURITIES are securities that are not registered for sale
          to the general public under the Securities Act of 1933, but that may
          be resold to certain institutional investors.

          STANDBY COMMITMENTS are obligations purchased by a Portfolio from a
          dealer that give the Portfolio the option to sell a security to the
          dealer at a specified price.

          STEP COUPON BONDS are debt securities that trade at a discount from
          their face value and pay coupon interest. The discount from the face
          value depends on the time remaining until cash payments begin,
          prevailing interest rates, liquidity of the security and the perceived
          credit quality of the issuer.

          STRIP BONDS are debt securities that are stripped of their interest
          (usually by a financial intermediary) after the securities are issued.
          The market value of these securities generally fluctuates more in
          response to changes in interest rates than interest-paying securities
          of comparable maturity.

          TENDER OPTION BONDS are generally long-term securities that are
          coupled with an option to tender the securities to a bank,
          broker-dealer or other financial institution at periodic intervals and
          receive the face value of the bond. This type of security is commonly
          used as a means of enhancing the security's liquidity.

          U.S. GOVERNMENT SECURITIES include direct obligations of the U.S.
          government that are supported by its full faith and credit. Treasury
          bills have initial maturities of less than one year, Treasury notes
          have initial maturities of one to ten years and Treasury bonds may be
          issued with any maturity but generally have maturities of at least ten
          years. U.S. government securities also include indirect obligations of
          the U.S. government that are issued by federal agencies and government
          sponsored entities. Unlike Treasury securities, agency securities
          generally are not backed by the full faith and credit of the U.S.
          government. Some agency securities are supported by the right of the
          issuer to borrow from the Treasury, others are supported by the
          discretionary authority of the U.S. government to purchase the
          agency's obligations and others are supported only by the credit of
          the sponsoring agency.

          VARIABLE AND FLOATING RATE SECURITIES have variable or floating rates
          of interest and, under certain limited circumstances, may have varying
          principal amounts. These securities pay interest at rates that are
          adjusted periodically according to a specified formula, usually with
          reference to some interest rate index or market interest rate. The
          floating rate tends to decrease the security's price sensitivity to
          changes in interest rates.

          WARRANTS are securities, typically issued with preferred stock or
          bonds, that give the holder the right to buy a proportionate amount of
          common stock at a specified price, usually at a price that is higher
          than the market price at the time of issuance of the warrant. The
          right may last for a period of years or indefinitely.

          WHEN-ISSUED, DELAYED DELIVERY AND FORWARD TRANSACTIONS generally
          involve the purchase of a security with payment and delivery at some
          time in the future - i.e., beyond normal settlement. The Portfolios do
          not earn interest on such securities until settlement and bear the
          risk of market value fluctuations in between the purchase and
          settlement dates. New issues of stocks and bonds, private placements
          and U.S. government securities may be sold in this manner.

          ZERO COUPON BONDS are debt securities that do not pay regular interest
          at regular intervals, but are issued at a discount from face value.
          The discount approximates the total amount of interest the security
          will accrue from the date of issuance to maturity. The market value of
          these securities generally fluctuates more in response to changes in
          interest rates than interest-paying securities.

II. FUTURES, OPTIONS AND OTHER DERIVATIVES

          FORWARD CONTRACTS are contracts to purchase or sell a specified amount
          of a financial instrument for an agreed upon price at a specified
          time. Forward contracts are not currently exchange traded and are
          typically negotiated on an individual basis. The Portfolios may enter
          into forward currency contracts to hedge against declines in the value
          of securities denominated in, or whose value is tied to, a currency
          other than the U.S. dollar or to reduce the impact of currency
          appreciation on purchases of such securities. They may also enter into
          forward contracts to purchase or sell securities or other financial
          indices.

          FUTURES CONTRACTS are contracts that obligate the buyer to receive and
          the seller to deliver an instrument or money at a specified price on a
          specified date. The Portfolios may buy and sell futures contracts on
          foreign currencies, securities and financial indices including
          interest rates or an index of U.S. government, foreign government,
          equity or fixed-income securities. The Portfolios may also buy options
          on futures contracts. An option on a futures contract gives the buyer
          the right, but not the obligation, to buy or sell a futures contract
          at a specified price on or before a specified date. Futures contracts
          and options on futures are standardized and traded on designated
          exchanges.

          INDEXED/STRUCTURED SECURITIES are typically short- to
          intermediate-term debt securities whose value at maturity or interest
          rate is linked to currencies, interest rates, equity securities,
          indices, commodity prices or other financial indicators. Such
          securities may be positively or negatively indexed (i.e. their value
          may increase or decrease if the reference index or instrument
          appreciates). Indexed/structured securities may have return
          characteristics similar to direct investments in the underlying
          instruments and may be more volatile than the underlying instruments.
          A Portfolio bears the market risk of an investment in the underlying
          instruments, as well as the credit risk of the issuer.

          INTEREST RATE SWAPS involve the exchange by two parties of their
          respective commitments to pay or receive interest (e.g., an exchange
          of floating rate payments for fixed rate payments).

          INVERSE FLOATERS are debt instruments whose interest rate bears an
          inverse relationship to the interest rate on another instrument or
          index. For example, upon reset the interest rate payable on a security
          may go down when the underlying index has risen. Certain inverse
          floaters may have an interest rate reset

          mechanism that multiplies the effects of change in the underlying
          index. Such mechanism may increase the volatility of the security's
          market value.

          OPTIONS are the right, but not the obligation, to buy or sell a
          specified amount of securities or other assets on or before a fixed
          date at a predetermined price. The Portfolios may purchase and write
          put and call options on securities, securities indices and foreign
          currencies.

                                                Explanation of rating categories

          The following is a description of credit ratings issued by two of the
          major credit ratings agencies. Credit ratings evaluate only the safety
          of principal and interest payments, not the market value risk of lower
          quality securities. Credit rating agencies may fail to change credit
          ratings to reflect subsequent events on a timely basis. Although Janus
          Capital considers security ratings when making investment decisions,
          it also performs its own investment analysis and does not rely solely
          on the ratings assigned by credit agencies.

                AA.......................... High quality; very strong capacity to pay principal and
                                             interest.
                A........................... Strong capacity to pay principal and interest; somewhat more
                                             susceptible to the adverse effects of changing circumstances
                                             and economic conditions.
                BBB......................... Adequate capacity to pay principal and interest; normally
                                             exhibit adequate protection parameters, but adverse economic
                                             conditions or changing circumstances more likely to lead to
                                             a weakened capacity to pay principal and interest than for
                                             higher rated bonds.
                Non-Investment Grade
                BB, B, CCC, CC, C........... Predominantly speculative with respect to the issuer's
                                             capacity to meet required interest and principal payments.
                                             BB - lowest degree of speculation; C - the highest degree of
                                             speculation. Quality and protective characteristics
                                             outweighed by large uncertainties or major risk exposure to

                                             low assurance of timely interest and principal payments or
                                             maintenance of other contract terms over time.
                Caa......................... Poor standing, may be in default; elements of danger with
                                             respect to principal or interest payments.
                Ca.......................... Speculative in a high degree; could be in default or have
                                             other marked shortcomings.
                C........................... Lowest-rated; extremely poor prospects of ever attaining
                                             investment standing.

          Unrated securities will be treated as noninvestment grade securities
          unless a portfolio manager determines that such securities are the
          equivalent of investment grade securities. Securities that have
          received ratings from more than one agency are considered investment
          grade if at least one agency has rated the security investment grade.

                 This Statement of Additional Information expands upon and
                 supplements the information contained in the current Prospectus
                 for the Institutional Shares (the "Shares") of the portfolios
                 listed above, each of which is a separate series of Janus Aspen
                 Series, a Delaware business trust. The Shares are sold under
                 the name "Janus Aspen Series." Each of these series of the
                 Trust represents shares of beneficial interest in a separate
                 portfolio of securities and other assets with its own objective
                 and policies. Each Portfolio is managed separately by Janus
                 Capital Corporation.

                 The Shares of the Portfolios may be purchased only by the
                 separate accounts of insurance companies for the purpose of
                 funding variable life insurance policies and variable annuity
                 contracts (collectively, "variable insurance contracts") and by
                 certain qualified retirement plans. Each Portfolio also offers
                 a second class of shares to certain participant directed
                 qualified plans.


                 This SAI is not a Prospectus and should be read in conjunction

CLASSIFICATION


          Each Portfolio is a series of the Trust, an open-end, management
          investment company. The Investment Company Act of 1940 ("1940 Act")
          classifies mutual funds as either diversified or nondiversified.
          Aggressive Growth Portfolio, Capital Appreciation Portfolio, Global
          Life Sciences Portfolio and Global Technology Portfolio are
          nondiversified funds. Each of these Portfolios reserves the right to
          become a diversified fund by limiting the investments in which more
          than 5% of its total assets are invested. Growth Portfolio, Balanced
          Portfolio, Equity Income Portfolio, Growth and Income Portfolio,
          International Growth Portfolio, Worldwide Growth Portfolio, Flexible
          Income Portfolio and High-Yield Portfolio are diversified funds.


PORTFOLIO TURNOVER

          The Prospectus includes a discussion of portfolio turnover policies.
          Portfolio turnover is calculated by dividing total purchases or sales,
          whichever is less, by the average monthly value of a Portfolio's
          securities. The following table summarizes the portfolio turnover
          rates for the fiscal periods indicated. The information below is for
          fiscal years ended December 31.

INVESTMENT POLICIES AND RESTRICTIONS APPLICABLE TO ALL PORTFOLIOS

          The Portfolios are subject to certain fundamental policies and
          restrictions that may not be changed without shareholder approval.
          Shareholder approval means approval by the lesser of (i) more than 50%
          of the outstanding voting securities of the Trust (or a particular
          Portfolio or particular class of shares if a matter affects just that
          Portfolio or that class of shares), or (ii) 67% or more of the voting
          securities present at a meeting if the holders of more than 50% of the
          outstanding voting securities of the Trust (or a particular Portfolio
          or class of shares) are present or represented by proxy. As
          fundamental policies, each of the Portfolios may not:


          (1) Own more than 10% of the outstanding voting securities of any one
          issuer and, as to fifty percent (50%) of the value of the total assets
          of Aggressive Growth Portfolio, Capital Appreciation Portfolio, Global
          Life Sciences Portfolio and Global Technology Portfolio and as to
          seventy-five percent (75%) of the value of the total assets of the
          other Portfolios, purchase the securities of any one issuer (except
          cash items and "government securities" as defined under the Investment
          Company Act of 1940, as amended, if immediately after and as a result
          of such purchase, the value of the holdings of a Portfolio in the
          securities of such issuer exceeds 5% of the value of such Portfolio's
          total assets. With respect to the other 50% of the


 2
<PAGE>


          value of its total assets, Aggressive Growth Portfolio, Capital
          Appreciation Portfolio, Global Life Sciences Portfolio and Global
          Technology Portfolio may invest in the securities of as few as two
          issuers.



          (2) Invest 25% or more of the value of their respective total assets
          in any particular industry (other than U.S. government securities).
          This policy does not apply to Global Life Sciences Portfolio or Global
          Technology Portfolio.


          (3) Invest directly in real estate or interests in real estate;
          however, the Portfolios may own debt or equity securities issued by
          companies engaged in those businesses.

          (4) Purchase or sell physical commodities other than foreign
          currencies unless acquired as a result of ownership of securities (but
          this limitation shall not prevent the Portfolios from purchasing or
          selling options, futures, swaps and forward contracts or from
          investing in securities or other instruments backed by physical
          commodities).

          (5) Lend any security or make any other loan if, as a result, more
          than 25% of a Portfolio's total assets would be lent to other parties
          (but this limitation does not apply to purchases of commercial paper,
          debt securities or repurchase agreements).

          (6) Act as an underwriter of securities issued by others, except to
          the extent that a Portfolio may be deemed an underwriter in connection
          with the disposition of its portfolio securities.

          As a fundamental policy, each Portfolio may, notwithstanding any other
          investment policy or limitation (whether or not fundamental), invest
          all of its assets in the securities of a single open-end management
          investment company with substantially the same fundamental investment
          objective, policies and limitations as such Portfolio.

          The Trustees have adopted additional investment restrictions for the
          Portfolios. These restrictions are operating policies of the
          Portfolios and may be changed by the Trustees without shareholder
          approval. The additional investment restrictions adopted by the
          Trustees to date include the following:

          (a) A Portfolio will not (i) enter into any futures contracts and
          related options for purposes other than bona fide hedging transactions
          within the meaning of Commodity Futures Trading Commission ("CFTC")
          regulations if the aggregate initial margin and premiums required to
          establish positions in futures contracts and related options that do
          not fall within the definition of bona fide hedging transactions will
          exceed 5% of the fair market value of a Portfolio's net assets, after
          taking into account unrealized profits and unrealized losses on any
          such contracts it has entered into; and (ii) enter into any futures
          contracts if the aggregate amount of such Portfolio's commitments
          under outstanding futures contracts positions would exceed the market
          value of its total assets.

          (b) The Portfolios do not currently intend to sell securities short,
          unless they own or have the right to obtain securities equivalent in
          kind and amount to the securities sold short without the payment of
          any additional consideration therefor, and provided that transactions
          in futures, options, swaps and forward contracts are not deemed to
          constitute selling securities short.

          (c) The Portfolios do not currently intend to purchase securities on
          margin, except that the Portfolios may obtain such short-term credits
          as are necessary for the clearance of transactions, and provided that
          margin payments and other deposits in connection with transactions in
          futures, options, swaps and forward contracts shall not be deemed to
          constitute purchasing securities on margin.

          (d) A Portfolio may not mortgage or pledge any securities owned or
          held by such Portfolio in amounts that exceed, in the aggregate, 15%
          of that Portfolio's net asset value, provided that this limitation
          does not

                                                                               3
<PAGE>

          apply to reverse repurchase agreements, deposits of assets to margin,
          guarantee positions in futures, options, swaps or forward contracts,
          or the segregation of assets in connection with such contracts.

          (e) The Portfolios may borrow money for temporary or emergency
          purposes (not for leveraging or investment) in an amount not exceeding
          25% of the value of their respective total assets (including the
          amount borrowed) less liabilities (other than borrowings). If
          borrowings exceed 25% of the value of a Portfolio's total assets by
          reason of a decline in net assets, the Portfolio will reduce its
          borrowings within three business days to the extent necessary to
          comply with the 25% limitation. This policy shall not prohibit reverse
          repurchase agreements, deposits of assets to margin or guarantee
          positions in futures, options, swaps or forward contracts, or the
          segregation of assets in connection with such contracts.

          (f) The Portfolios do not currently intend to purchase any security or
          enter into a repurchase agreement, if as a result, more than 15% of
          their respective net assets would be invested in repurchase agreements
          not entitling the holder to payment of principal and interest within
          seven days and in securities that are illiquid by virtue of legal or
          contractual restrictions on resale or the absence of a readily
          available market. The Trustees, or the Portfolios' investment adviser
          acting pursuant to authority delegated by the Trustees, may determine
          that a readily available market exists for securities eligible for
          resale pursuant to Rule 144A under the Securities Act of 1933 ("Rule
          144A Securities"), or any successor to such rule, Section 4(2)
          commercial paper and municipal lease obligations. Accordingly, such
          securities may not be subject to the foregoing limitation.

          (g) The Portfolios may not invest in companies for the purpose of
          exercising control of management.

          Under the terms of an exemptive order received from the Securities and
          Exchange Commission ("SEC"), each of the Portfolios may borrow money
          from or lend money to other funds that permit such transactions and
          for which Janus Capital serves as investment adviser. All such
          borrowing and lending will be subject to the above limits. A Portfolio
          will borrow money through the program only when the costs are equal to
          or lower than the cost of bank loans. Interfund loans and borrowings
          normally extend overnight, but can have a maximum duration of seven
          days. A Portfolio will lend through the program only when the returns
          are higher than those available from other short-term instruments
          (such as repurchase agreements). A Portfolio may have to borrow from a
          bank at a higher interest rate if an interfund loan is called or not
          renewed. Any delay in repayment to a lending Portfolio could result in
          a lost investment opportunity or additional borrowing costs.

          For the purposes of these investment restrictions, the identification
          of the issuer of a municipal obligation depends on the terms and
          conditions of the security. When assets and revenues of a political
          subdivision are separate from those of the government that created the
          subdivision and the security is backed only by the assets and revenues
          of the subdivision, the subdivision is deemed to be the sole issuer.
          Similarly, in the case of an industrial development bond, if the bond
          is backed only by assets and revenues of a nongovernmental user, then
          the nongovernmental user would be deemed to be the sole issuer. If,
          however, in either case, the creating government or some other entity
          guarantees the security, the guarantee would be considered a separate
          security that would be treated as an issue of the guaranteeing entity.

          For purposes of the Portfolios' restriction on investing in a
          particular industry, the Portfolios will rely primarily on industry
          classifications as published by Bloomberg L.P. To the extent that
          Bloomberg L.P. classifications are so broad that the primary economic
          characteristics in a single class are materially different, the
          Portfolios may further classify issuers in accordance with industry
          classifications as published by the SEC.

INVESTMENT POLICIES APPLICABLE TO CERTAIN PORTFOLIOS

          BALANCED PORTFOLIO. As an operational policy, at least 25% of the
          assets of Balanced Portfolio normally will be invested in fixed-income
          securities.


          GLOBAL LIFE SCIENCES PORTFOLIO. As a fundamental policy, Global Life
          Sciences Portfolio will normally invest at least 25% of its total
          assets, in the aggregate, in the following industry groups: health
          care; pharmaceuticals; agriculture; cosmetics/personal care; and
          biotechnology.


          FLEXIBLE INCOME PORTFOLIO. As a fundamental policy, this Portfolio may
          not purchase a non-income-producing security if, after such purchase,
          less than 80% of the Portfolio's total assets would be invested in
          income-producing securities. Income-producing securities include
          securities that make periodic interest payments as well as those that
          make interest payments on a deferred basis or pay interest only at
          maturity (e.g., Treasury bills or zero coupon bonds).

INVESTMENT STRATEGIES AND RISKS

Cash Position


          As discussed in the Prospectus, when a portfolio manager believes that
          market conditions are unfavorable for profitable investing, or when he
          or she is otherwise unable to locate attractive investment
          opportunities, the Portfolio's investment in cash and similar
          investments may increase. Securities that the Portfolios may invest in
          as a means of receiving a return on idle cash include commercial
          paper, certificates of deposit, repurchase agreements or other
          short-term debt obligations. The Portfolios may also invest in money
          market funds, including funds managed by Janus Capital. (See
          "Investment Company Securities" on page 8).


Illiquid Investments

          Each Portfolio may invest up to 15% of its net assets in illiquid
          investments (i.e., securities that are not readily marketable). The
          Trustees have authorized Janus Capital to make liquidity
          determinations with respect to certain securities, including Rule 144A
          Securities, commercial paper and municipal lease obligations purchased
          by the Portfolios. Under the guidelines established by the Trustees,
          Janus Capital will consider the following factors: (1) the frequency
          of trades and quoted prices for the obligation; (2) the number of
          dealers willing to purchase or sell the security and the number of
          other potential purchasers; (3) the willingness of dealers to
          undertake to make a market in the security; and (4) the nature of the
          security and the nature of the marketplace trades, including the time
          needed to dispose of the security, the method of soliciting offers and
          the mechanics of the transfer. In the case of commercial paper, Janus
          Capital will also consider whether the paper is traded flat or in
          default as to principal and interest and any ratings of the paper by a
          nationally recognized statistical rating organization ("NRSRO"). A
          foreign security that may be freely traded on or through the
          facilities of an offshore exchange or other established offshore
          securities market is not deemed to be a restricted security subject to
          these procedures.

          If illiquid securities exceed 15% of a Portfolio's net assets after
          the time of purchase the Portfolio will take steps to reduce in an
          orderly fashion its holdings of illiquid securities. Because illiquid
          securities may not be readily marketable, a portfolio manager may not
          be able to dispose of them in a timely manner. As a result, a
          Portfolio may be forced to hold illiquid securities while their price
          depreciates. Depreciation in the price of illiquid securities may
          cause the net asset value of a Portfolio to decline.

                                                                               5
<PAGE>


Securities Lending



          The Portfolios may lend securities to qualified parties (typically
          brokers or other financial institutions) who need to borrow securities
          in order to complete certain transactions such as covering short
          sales, avoiding failures to deliver securities or completing arbitrage
          activities. The Portfolios may seek to earn additional income through
          securities lending. Since there is the risk of delay in recovering a
          loaned security or the risk of loss in collateral rights if the
          borrower fails financially, securities lending will only be made to
          parties that Janus Capital deems creditworthy and in good standing. In
          addition, such loans will only be made if Janus Capital believes the
          benefit from granting such loans justifies the risk. The Portfolios
          will not have the right to vote on securities while they are being
          lent, but it will generally call a loan in anticipation of any
          important vote. All loans will be continuously secured by collateral
          which consists of cash, U.S. government securities, letters of credit
          and such other collateral permitted by the SEC and policies approved
          by the Trustees. Cash collateral may be invested in money market funds
          advised by Janus to the extent consistent with exemptive relief
          obtained from the SEC.


Short Sales

          Each Portfolio may engage in "short sales against the box." This
          technique involves selling either a security that a Portfolio owns, or
          a security equivalent in kind and amount to the security sold short
          that the Portfolio has the right to obtain, for delivery at a
          specified date in the future. A Portfolio may enter into a short sale
          against the box to hedge against anticipated declines in the market
          price of portfolio securities. If the value of the securities sold
          short increases prior to the scheduled delivery date, a Portfolio
          loses the opportunity to participate in the gain.

Zero Coupon, Step Coupon and Pay-In-Kind Securities

          Each Portfolio may invest up to 10% (without limit for High-Yield
          Portfolio and Flexible Income Portfolio) of its assets in zero coupon,
          pay-in-kind and step coupon securities. Zero coupon bonds are issued
          and traded at a discount from their face value. They do not entitle
          the holder to any periodic payment of interest prior to maturity. Step
          coupon bonds trade at a discount from their face value and pay coupon
          interest. The coupon rate is low for an initial period and then
          increases to a higher coupon rate thereafter. The discount from the
          face amount or par value depends on the time remaining until cash
          payments begin, prevailing interest rates, liquidity of the security
          and the perceived credit quality of the issuer. Pay-in-kind bonds
          normally give the issuer an option to pay cash at a coupon payment
          date or give the holder of the security a similar bond with the same
          coupon rate and a face value equal to the amount of the coupon payment
          that would have been made. For the purposes of any Portfolio's
          restriction on investing in income-producing securities,
          income-producing securities include securities that make periodic
          interest payments as well as those that make interest payments on a
          deferred basis or pay interest only at maturity (e.g., Treasury bills
          or zero coupon bonds).

          Current federal income tax law requires holders of zero coupon
          securities and step coupon securities to report the portion of the
          original issue discount on such securities that accrues during a given
          year as interest income, even though the holders receive no cash
          payments of interest during the year. In order to qualify as a
          "regulated investment company" under the Internal Revenue Code of 1986
          and the regulations thereunder (the "Code"), a Portfolio must
          distribute its investment company taxable income, including the
          original issue discount accrued on zero coupon or step coupon bonds.
          Because a Portfolio will not receive cash payments on a current basis
          in respect of accrued original-issue discount on zero coupon bonds or
          step coupon bonds during the period before interest payments begin, in
          some years that Portfolio may have to distribute cash obtained from
          other sources in order to satisfy the distribution requirements under
          the Code. A Portfolio might obtain such cash from selling other
          portfolio holdings which might cause that

 6
<PAGE>

          Portfolio to incur capital gains or losses on the sale. Additionally,
          these actions are likely to reduce the assets to which Portfolio
          expenses could be allocated and to reduce the rate of return for that
          Portfolio. In some circumstances, such sales might be necessary in
          order to satisfy cash distribution requirements even though investment
          considerations might otherwise make it undesirable for a Portfolio to
          sell the securities at the time.

          Generally, the market prices of zero coupon, step coupon and
          pay-in-kind securities are more volatile than the prices of securities
          that pay interest periodically and in cash and are likely to respond
          to changes in interest rates to a greater degree than other types of
          debt securities having similar maturities and credit quality.

Pass-Through Securities

          The Portfolios may invest in various types of pass-through securities,
          such as mortgage-backed securities, asset-backed securities and
          participation interests. A pass-through security is a share or
          certificate of interest in a pool of debt obligations that have been
          repackaged by an intermediary, such as a bank or broker-dealer. The
          purchaser of a pass-through security receives an undivided interest in
          the underlying pool of securities. The issuers of the underlying
          securities make interest and principal payments to the intermediary
          which are passed through to purchasers, such as the Portfolios. The
          most common type of pass-through securities are mortgage-backed
          securities. Government National Mortgage Association ("GNMA")
          Certificates are mortgage-backed securities that evidence an undivided
          interest in a pool of mortgage loans. GNMA Certificates differ from
          bonds in that principal is paid back monthly by the borrowers over the
          term of the loan rather than returned in a lump sum at maturity. A
          Portfolio will generally purchase "modified pass-through" GNMA
          Certificates, which entitle the holder to receive a share of all
          interest and principal payments paid and owned on the mortgage pool,
          net of fees paid to the "issuer" and GNMA, regardless of whether or
          not the mortgagor actually makes the payment. GNMA Certificates are
          backed as to the timely payment of principal and interest by the full
          faith and credit of the U.S. government.

          The Federal Home Loan Mortgage Corporation ("FHLMC") issues two types
          of mortgage pass-through securities: mortgage participation
          certificates ("PCs") and guaranteed mortgage certificates ("GMCs").
          PCs resemble GNMA Certificates in that each PC represents a pro rata
          share of all interest and principal payments made and owned on the
          underlying pool. FHLMC guarantees timely payments of interest on PCs
          and the full return of principal. GMCs also represent a pro rata
          interest in a pool of mortgages. However, these instruments pay
          interest semiannually and return principal once a year in guaranteed
          minimum payments. This type of security is guaranteed by FHLMC as to
          timely payment of principal and interest but it is not guaranteed by
          the full faith and credit of the U.S. government.

          The Federal National Mortgage Association ("FNMA") issues guaranteed
          mortgage pass-through certificates ("FNMA Certificates"). FNMA
          Certificates resemble GNMA Certificates in that each FNMA Certificate
          represents a pro rata share of all interest and principal payments
          made and owned on the underlying pool. This type of security is
          guaranteed by FNMA as to timely payment of principal and interest but
          it is not guaranteed by the full faith and credit of the U.S.
          government.

          Except for GMCs, each of the mortgage-backed securities described
          above is characterized by monthly payments to the holder, reflecting
          the monthly payments made by the borrowers who received the underlying
          mortgage loans. The payments to the security holders (such as the
          Portfolios), like the payments on the underlying loans, represent both
          principal and interest. Although the underlying mortgage loans are for
          specified periods of time, such as 20 or 30 years, the borrowers can,
          and typically do, pay

                                                                               7

          them off sooner. Thus, the security holders frequently receive
          prepayments of principal in addition to the principal that is part of
          the regular monthly payments. A portfolio manager will consider
          estimated prepayment rates in calculating the average-weighted
          maturity of a Portfolio. A borrower is more likely to prepay a
          mortgage that bears a relatively high rate of interest. This means
          that in times of declining interest rates, higher yielding
          mortgage-backed securities held by a Portfolio might be converted to
          cash and that Portfolio will be forced to accept lower interest rates
          when that cash is used to purchase additional securities in the
          mortgage-backed securities sector or in other investment sectors.
          Additionally, prepayments during such periods will limit a Portfolio's
          ability to participate in as large a market gain as may be experienced
          with a comparable security not subject to prepayment.

          Asset-backed securities represent interests in pools of consumer loans
          and are backed by paper or accounts receivables originated by banks,
          credit card companies or other providers of credit. Generally, the
          originating bank or credit provider is neither the obligor nor the
          guarantor of the security, and interest and principal payments
          ultimately depend upon payment of the underlying loans by individuals.
          Tax-exempt asset-backed securities include units of beneficial
          interests in pools of purchase contracts, financing leases, and sales
          agreements that may be created when a municipality enters into an
          installment purchase contract or lease with a vendor. Such securities
          may be secured by the assets purchased or leased by the municipality;
          however, if the municipality stops making payments, there generally
          will be no recourse against the vendor. The market for tax-exempt
          asset-backed securities is still relatively new. These obligations are
          likely to involve unscheduled prepayments of principal.

Investment Company Securities

          From time to time, the Portfolios may invest in securities of other
          investment companies, subject to the provisions of Section 12(d)(1) of
          the 1940 Act. The Portfolios may invest in securities of money market
          funds managed by Janus Capital in excess of the limitations of Section
          12(d)(1) under the terms of an SEC exemptive order obtained by Janus
          Capital and the Janus funds.

Depositary Receipts


          The Portfolios may invest in sponsored and unsponsored American
          Depositary Receipts ("ADRs"), which are receipts issued by an American
          bank or trust company evidencing ownership of underlying securities
          issued by a foreign issuer. ADRs, in registered form, are designed for
          use in U.S. securities markets. Unsponsored ADRs may be created
          without the participation of the foreign issuer. Holders of these ADRs
          generally bear all the costs of the ADR facility, whereas foreign
          issuers typically bear certain costs in a sponsored ADR. The bank or
          trust company depositary of an unsponsored ADR may be under no
          obligation to distribute shareholder communications received from the
          foreign issuer or to pass through voting rights. The Portfolios may
          also invest in European Depositary Receipts ("EDRs"), Global
          Depositary Receipts ("GDRs") and in other similar instruments
          representing securities of foreign companies. EDRs and GDRs are
          securities that are typically issued by foreign banks or foreign trust
          companies, although U.S. banks or U.S. trust companies may issue them.
          EDRs and GDRs are structured similarly to the arrangements of ADRs.
          EDRs, in bearer form, are designed for use in European securities
          markets.


          Depositary Receipts are generally subject to the same sort of risks as
          direct investments in a foreign country, such as, currency risk,
          political and economic risk, and market risk, because their values
          depend on the performance of a foreign security denominated in its
          home currency. The risks of foreign investing are addressed in some
          detail in the Portfolios' prospectus.

Municipal Obligations

          The Portfolios may invest in municipal obligations issued by states,
          territories and possessions of the United States and the District of
          Columbia. The value of municipal obligations can be affected by
          changes in their actual or perceived credit quality. The credit
          quality of municipal obligations can be affected by, among other
          things, the financial condition of the issuer or guarantor, the
          issuer's future borrowing plans and sources of revenue, the economic
          feasibility of the revenue bond project or general borrowing purpose,
          political or economic developments in the region where the security is
          issued, and the liquidity of the security. Because municipal
          securities are generally traded over-the-counter, the liquidity of a
          particular issue often depends on the willingness of dealers to make a
          market in the security. The liquidity of some municipal obligations
          may be enhanced by demand features, which would enable a Portfolio to
          demand payment on short notice from the issuer or a financial
          intermediary.

Other Income-Producing Securities

          Other types of income producing securities that the Portfolios may
          purchase include, but are not limited to, the following types of
          securities:

          VARIABLE AND FLOATING RATE OBLIGATIONS. These types of securities have
          variable or floating rates of interest and, under certain limited
          circumstances, may have varying principal amounts. These securities
          pay interest at rates that are adjusted periodically according to a
          specified formula, usually with reference to some interest rate index
          or market interest rate. The floating rate tends to decrease the
          security's price sensitivity to changes in interest rates. These types
          of securities are relatively long-term instruments that often carry
          demand features permitting the holder to demand payment of principal
          at any time or at specified intervals prior to maturity.

          In order to most effectively use these investments, a portfolio
          manager must correctly assess probable movements in interest rates.
          This involves different skills than those used to select most
          portfolio securities. If the portfolio manager incorrectly forecasts
          such movements, a Portfolio could be adversely affected by the use of
          variable or floating rate obligations.

          STANDBY COMMITMENTS. These instruments, which are similar to a put,
          give a Portfolio the option to obligate a broker, dealer or bank to
          repurchase a security held by that Portfolio at a specified price.

          TENDER OPTION BONDS. Tender option bonds are relatively long-term
          bonds that are coupled with the agreement of a third party (such as a
          broker, dealer or bank) to grant the holders of such securities the
          option to tender the securities to the institution at periodic
          intervals.

          INVERSE FLOATERS. Inverse floaters are debt instruments whose interest
          bears an inverse relationship to the interest rate on another
          security. No Portfolio will invest more than 5% of its assets in
          inverse floaters. Similar to variable and floating rate obligations,
          effective use of inverse floaters requires skills different from those
          needed to select most portfolio securities. If movements in interest
          rates are incorrectly anticipated, a fund could lose money or its NAV
          could decline by the use of inverse floaters.

          STRIP BONDS. Strip bonds are debt securities that are stripped of
          their interest (usually by a financial intermediary) after the
          securities are issued. The market value of these securities generally
          fluctuates more in response to changes in interest rates than
          interest-paying securities of comparable maturity.

          The Portfolios will purchase standby commitments, tender option bonds
          and instruments with demand features primarily for the purpose of
          increasing the liquidity of their holdings.

                                                                               9

Repurchase and Reverse Repurchase Agreements

          In a repurchase agreement, a Portfolio purchases a security and
          simultaneously commits to resell that security to the seller at an
          agreed upon price on an agreed upon date within a number of days
          (usually not more than seven) from the date of purchase. The resale
          price consists of the purchase price plus an agreed upon incremental
          amount that is unrelated to the coupon rate or maturity of the
          purchased security. A repurchase agreement involves the obligation of
          the seller to pay the agreed upon price, which obligation is in effect
          secured by the value (at least equal to the amount of the agreed upon
          resale price and marked-to-market daily) of the underlying security or
          "collateral." A risk associated with repurchase agreements is the
          failure of the seller to repurchase the securities as agreed, which
          may cause a Portfolio to suffer a loss if the market value of such
          securities declines before they can be liquidated on the open market.
          In the event of bankruptcy or insolvency of the seller, a Portfolio
          may encounter delays and incur costs in liquidating the underlying
          security. Repurchase agreements that mature in more than seven days
          are subject to the 15% limit on illiquid investments. While it is not
          possible to eliminate all risks from these transactions, it is the
          policy of the Portfolios to limit repurchase agreements to those
          parties whose creditworthiness has been reviewed and found
          satisfactory by Janus Capital.

          A Portfolio may use reverse repurchase agreements to obtain cash to
          satisfy unusually heavy redemption requests or for other temporary or
          emergency purposes without the necessity of selling portfolio
          securities, or to earn additional income on portfolio securities, such
          as Treasury bills or notes. In a reverse repurchase agreement, a
          Portfolio sells a portfolio security to another party, such as a bank
          or broker-dealer, in return for cash and agrees to repurchase the
          instrument at a particular price and time. While a reverse repurchase
          agreement is outstanding, a Portfolio will maintain cash and
          appropriate liquid assets in a segregated custodial account to cover
          its obligation under the agreement. The Portfolios will enter into
          reverse repurchase agreements only with parties that Janus Capital
          deems creditworthy. Using reverse repurchase agreements to earn
          additional income involves the risk that the interest earned on the
          invested proceeds is less than the expense of the reverse repurchase
          agreement transaction. This technique may also have a leveraging
          effect on the Portfolio, although the Portfolio's intent to segregate
          assets in the amount of the reverse repurchase agreement minimizes
          this effect.


High-Yield/High-Risk Bonds



          Flexible Income Portfolio and High-Yield Portfolio may invest without
          limit in bonds that are rated below investment grade (e.g., bonds
          rated BB or lower by Standard & Poor's Ratings Services or Ba or lower
          by Moody's Investors Service, Inc.). No other Portfolio intends to
          invest 35% or more of its net assets in such bonds. Lower rated bonds
          involve a higher degree of credit risk, which is the risk that the
          issuer will not make interest or principal payments when due. In the
          event of an unanticipated default, a Portfolio would experience a
          reduction in its income, and could expect a decline in the market
          value of the bonds so affected.



          Any Portfolio may also invest in unrated debt bonds of foreign and
          domestic issuers. Unrated bonds, while not necessarily of lower
          quality than rated bonds, may not have as broad a market. Because of
          the size and perceived demand of the issue, among other factors,
          certain municipalities may not incur the costs of obtaining a rating.
          A Portfolio's manager will analyze the creditworthiness of the issuer,
          as well as any financial institution or other party responsible for
          payments on the bond, in determining whether to purchase unrated
          municipal bonds. Unrated bonds will be included in the 35% limit of
          each Portfolio unless its manager deems such securities to be the
          equivalent of investment grade bonds.


          Subject to the above limits, each Portfolio may purchase defaulted
          securities only when its portfolio manager believes, based upon
          analysis of the financial condition, results of operations and
          economic

 10
<PAGE>

          outlook of an issuer, that there is potential for resumption of income
          payments and that the securities offer an unusual opportunity for
          capital appreciation. Notwithstanding the portfolio manager's belief
          about the resumption of income, however, the purchase of any security
          on which payment of interest or dividends is suspended involves a high
          degree of risk. Such risk includes, among other things, the following:

          FINANCIAL AND MARKET RISKS. Investments in securities that are in
          default involve a high degree of financial and market risks that can
          result in substantial or, at times, even total losses. Issuers of
          defaulted securities may have substantial capital needs and may become
          involved in bankruptcy or reorganization proceedings. Among the
          problems involved in investments in such issuers is the fact that it
          may be difficult to obtain information about the condition of such
          issuers. The market prices of such securities also are subject to
          abrupt and erratic movements and above average price volatility, and
          the spread between the bid and asked prices of such securities may be
          greater than normally expected.

          DISPOSITION OF PORTFOLIO SECURITIES. Although these Portfolios
          generally will purchase securities for which their portfolio managers
          expect an active market to be maintained, defaulted securities may be
          less actively traded than other securities and it may be difficult to
          dispose of substantial holdings of such securities at prevailing
          market prices. The Portfolios will limit holdings of any such
          securities to amounts that the portfolio managers believe could be
          readily sold, and holdings of such securities would, in any event, be
          limited so as not to limit the Portfolios' ability to readily dispose
          of securities to meet redemptions.

          OTHER. Defaulted securities require active monitoring and may, at
          times, require participation in bankruptcy or receivership proceedings
          on behalf of the Portfolios.

Futures, Options and Other Derivative Instruments

          FUTURES CONTRACTS. The Portfolios may enter into contracts for the
          purchase or sale for future delivery of fixed-income securities,
          foreign currencies or contracts based on financial indices, including
          indices of U.S. government securities, foreign government securities,
          equity or fixed-income securities. U.S. futures contracts are traded
          on exchanges which have been designated "contract markets" by the CFTC
          and must be executed through a futures commission merchant ("FCM"), or
          brokerage firm, which is a member of the relevant contract market.
          Through their clearing corporations, the exchanges guarantee
          performance of the contracts as between the clearing members of the
          exchange.

          The buyer or seller of a futures contract is not required to deliver
          or pay for the underlying instrument unless the contract is held until
          the delivery date. However, both the buyer and seller are required to
          deposit "initial margin" for the benefit of the FCM when the contract
          is entered into. Initial margin deposits are equal to a percentage of
          the contract's value, as set by the exchange on which the contract is
          traded, and may be maintained in cash or certain other liquid assets
          by the Portfolios' custodian or subcustodian for the benefit of the
          FCM. Initial margin payments are similar to good faith deposits or
          performance bonds. Unlike margin extended by a securities broker,
          initial margin payments do not constitute purchasing securities on
          margin for purposes of the Portfolio's investment limitations. If the
          value of either party's position declines, that party will be required
          to make additional "variation margin" payments for the benefit of the
          FCM to settle the change in value on a daily basis. The party that has
          a gain may be entitled to receive all or a portion of this amount. In
          the event of the bankruptcy of the FCM that holds margin on behalf of
          a Portfolio, that Portfolio may be entitled to return of margin owed
          to such Portfolio only in proportion to the amount received by the
          FCM's other customers. Janus Capital will attempt to minimize the risk
          by careful monitoring of the creditworthiness of the FCMs with which
          the Portfolios do business and by depositing margin payments in a
          segregated account with the Portfolios' custodian.

                                                                              11

          The Portfolios intend to comply with guidelines of eligibility for
          exclusion from the definition of the term "commodity pool operator"
          adopted by the CFTC and the National Futures Association, which
          regulate trading in the futures markets. The Portfolios will use
          futures contracts and related options primarily for bona fide hedging
          purposes within the meaning of CFTC regulations. To the extent that
          the Portfolios hold positions in futures contracts and related options
          that do not fall within the definition of bona fide hedging
          transactions, the aggregate initial margin and premiums required to
          establish such positions will not exceed 5% of the fair market value
          of a Portfolio's net assets, after taking into account unrealized
          profits and unrealized losses on any such contracts it has entered
          into.

          Although a Portfolio will segregate cash and liquid assets in an
          amount sufficient to cover its open futures obligations, the
          segregated assets would be available to that Portfolio immediately
          upon closing out the futures position, while settlement of securities
          transactions could take several days. However, because a Portfolio's
          cash that may otherwise be invested would be held uninvested or
          invested in other liquid assets so long as the futures position
          remains open, such Portfolio's return could be diminished due to the
          opportunity losses of foregoing other potential investments.

          A Portfolio's primary purpose in entering into futures contracts is to
          protect that Portfolio from fluctuations in the value of securities or
          interest rates without actually buying or selling the underlying debt
          or equity security. For example, if the Portfolio anticipates an
          increase in the price of stocks, and it intends to purchase stocks at
          a later time, that Portfolio could enter into a futures contract to
          purchase a stock index as a temporary substitute for stock purchases.
          If an increase in the market occurs that influences the stock index as
          anticipated, the value of the futures contracts will increase, thereby
          serving as a hedge against that Portfolio not participating in a
          market advance. This technique is sometimes known as an anticipatory
          hedge. To the extent a Portfolio enters into futures contracts for
          this purpose, the segregated assets maintained to cover such
          Portfolio's obligations with respect to the futures contracts will
          consist of liquid assets from its portfolio in an amount equal to the
          difference between the contract price and the aggregate value of the
          initial and variation margin payments made by that Portfolio with
          respect to the futures contracts. Conversely, if a Portfolio holds
          stocks and seeks to protect itself from a decrease in stock prices,
          the Portfolio might sell stock index futures contracts, thereby hoping
          to offset the potential decline in the value of its portfolio
          securities by a corresponding increase in the value of the futures
          contract position. A Portfolio could protect against a decline in
          stock prices by selling portfolio securities and investing in money
          market instruments, but the use of futures contracts enables it to
          maintain a defensive position without having to sell portfolio
          securities.


          If a Portfolio owns bonds and the portfolio manager expects interest
          rates to increase, that Portfolio may take a short position in
          interest rate futures contracts. Taking such a position would have
          much the same effect as that Portfolio selling bonds in its portfolio.
          If interest rates increase as anticipated, the value of the bonds
          would decline, but the value of that Portfolio's interest rate futures
          contract will increase, thereby keeping the net asset value of that
          Portfolio from declining as much as it may have otherwise. If, on the
          other hand, a portfolio manager expects interest rates to decline,
          that Portfolio may take a long position in interest rate futures
          contracts in anticipation of later closing out the futures position
          and purchasing the bonds. Although a Portfolio can accomplish similar
          results by buying securities with long maturities and selling
          securities with short maturities, given the greater liquidity of the
          futures market than the cash market, it may be possible to accomplish
          the same result more easily and more quickly by using futures
          contracts as an investment tool to reduce risk.


          The ordinary spreads between prices in the cash and futures markets,
          due to differences in the nature of those markets, are subject to
          distortions. First, all participants in the futures market are subject
          to initial margin and variation margin requirements. Rather than
          meeting additional variation margin requirements,

 12
<PAGE>

          investors may close out futures contracts through offsetting
          transactions which could distort the normal price relationship between
          the cash and futures markets. Second, the liquidity of the futures
          market depends on participants entering into offsetting transactions
          rather than making or taking delivery of the instrument underlying a
          futures contract. To the extent participants decide to make or take
          delivery, liquidity in the futures market could be reduced and prices
          in the futures market distorted. Third, from the point of view of
          speculators, the margin deposit requirements in the futures market are
          less onerous than margin requirements in the securities market.
          Therefore, increased participation by speculators in the futures
          market may cause temporary price distortions. Due to the possibility
          of the foregoing distortions, a correct forecast of general price
          trends by a portfolio manager still may not result in a successful use
          of futures.

          Futures contracts entail risks. Although the Portfolios believe that
          use of such contracts will benefit the Portfolios, a Portfolio's
          overall performance could be worse than if such Portfolio had not
          entered into futures contracts if the portfolio manager's investment
          judgement proves incorrect. For example, if a Portfolio has hedged
          against the effects of a possible decrease in prices of securities
          held in its portfolio and prices increase instead, that Portfolio will
          lose part or all of the benefit of the increased value of these
          securities because of offsetting losses in its futures positions. In
          addition, if a Portfolio has insufficient cash, it may have to sell
          securities from its portfolio to meet daily variation margin
          requirements. Those sales may be, but will not necessarily be, at
          increased prices which reflect the rising market and may occur at a
          time when the sales are disadvantageous to such Portfolio.

          The prices of futures contracts depend primarily on the value of their
          underlying instruments. Because there are a limited number of types of
          futures contracts, it is possible that the standardized futures
          contracts available to a Portfolio will not match exactly such
          Portfolio's current or potential investments. A Portfolio may buy and
          sell futures contracts based on underlying instruments with different
          characteristics from the securities in which it typically
          invests - for example, by hedging investments in portfolio securities
          with a futures contract based on a broad index of securities - which
          involves a risk that the futures position will not correlate precisely
          with the performance of such Portfolio's investments.

          Futures prices can also diverge from the prices of their underlying
          instruments, even if the underlying instruments closely correlate with
          a Portfolio's investments. Futures prices are affected by factors such
          as current and anticipated short-term interest rates, changes in
          volatility of the underlying instruments and the time remaining until
          expiration of the contract. Those factors may affect securities prices
          differently from futures prices. Imperfect correlations between a
          Portfolio's investments and its futures positions also may result from
          differing levels of demand in the futures markets and the securities
          markets, from structural differences in how futures and securities are
          traded, and from imposition of daily price fluctuation limits for
          futures contracts. A Portfolio may buy or sell futures contracts with
          a greater or lesser value than the securities it wishes to hedge or is
          considering purchasing in order to attempt to compensate for
          differences in historical volatility between the futures contract and
          the securities, although this may not be successful in all cases. If
          price changes in a Portfolio's futures positions are poorly correlated
          with its other investments, its futures positions may fail to produce
          desired gains or result in losses that are not offset by the gains in
          that Portfolio's other investments.

          Because futures contracts are generally settled within a day from the
          date they are closed out, compared with a settlement period of three
          days for some types of securities, the futures markets can provide
          superior liquidity to the securities markets. Nevertheless, there is
          no assurance that a liquid secondary market will exist for any
          particular futures contract at any particular time. In addition,
          futures exchanges may establish daily price fluctuation limits for
          futures contracts and may halt trading if a contract's price

                                                                              13
<PAGE>

          moves upward or downward more than the limit in a given day. On
          volatile trading days when the price fluctuation limit is reached, it
          may be impossible for a Portfolio to enter into new positions or close
          out existing positions. If the secondary market for a futures contract
          is not liquid because of price fluctuation limits or otherwise, a
          Portfolio may not be able to promptly liquidate unfavorable futures
          positions and potentially could be required to continue to hold a
          futures position until the delivery date, regardless of changes in its
          value. As a result, such Portfolio's access to other assets held to
          cover its futures positions also could be impaired.

          OPTIONS ON FUTURES CONTRACTS. The Portfolios may buy and write put and
          call options on futures contracts. An option on a future gives a
          Portfolio the right (but not the obligation) to buy or sell a futures
          contract at a specified price on or before a specified date. The
          purchase of a call option on a futures contract is similar in some
          respects to the purchase of a call option on an individual security.
          Depending on the pricing of the option compared to either the price of
          the futures contract upon which it is based or the price of the
          underlying instrument, ownership of the option may or may not be less
          risky than ownership of the futures contract or the underlying
          instrument. As with the purchase of futures contracts, when a
          Portfolio is not fully invested it may buy a call option on a futures
          contract to hedge against a market advance.

          The writing of a call option on a futures contract constitutes a
          partial hedge against declining prices of the security or foreign
          currency which is deliverable under, or of the index comprising, the
          futures contract. If the futures price at the expiration of the option
          is below the exercise price, a Portfolio will retain the full amount
          of the option premium which provides a partial hedge against any
          decline that may have occurred in that Portfolio's holdings. The
          writing of a put option on a futures contract constitutes a partial
          hedge against increasing prices of the security or foreign currency
          which is deliverable under, or of the index comprising, the futures
          contract. If the futures price at expiration of the option is higher
          than the exercise price, a Portfolio will retain the full amount of
          the option premium which provides a partial hedge against any increase
          in the price of securities which that Portfolio is considering buying.
          If a call or put option a Portfolio has written is exercised, such
          Portfolio will incur a loss which will be reduced by the amount of the
          premium it received. Depending on the degree of correlation between
          the change in the value of its portfolio securities and changes in the
          value of the futures positions, a Portfolio's losses from existing
          options on futures may to some extent be reduced or increased by
          changes in the value of portfolio securities.

          The purchase of a put option on a futures contract is similar in some
          respects to the purchase of protective put options on portfolio
          securities. For example, a Portfolio may buy a put option on a futures
          contract to hedge its portfolio against the risk of falling prices or
          rising interest rates.

          The amount of risk a Portfolio assumes when it buys an option on a
          futures contract is the premium paid for the option plus related
          transaction costs. In addition to the correlation risks discussed
          above, the purchase of an option also entails the risk that changes in
          the value of the underlying futures contract will not be fully
          reflected in the value of the options bought.

          FORWARD CONTRACTS. A forward contract is an agreement between two
          parties in which one party is obligated to deliver a stated amount of
          a stated asset at a specified time in the future and the other party
          is obligated to pay a specified amount for the assets at the time of
          delivery. The Portfolios may enter into forward contracts to purchase
          and sell government securities, equity or income securities, foreign
          currencies or other financial instruments. Forward contracts generally
          are traded in an interbank market conducted directly between traders
          (usually large commercial banks) and their customers. Unlike futures
          contracts, which are standardized contracts, forward contracts can be
          specifically drawn to meet the needs

 14
<PAGE>

          of the parties that enter into them. The parties to a forward contract
          may agree to offset or terminate the contract before its maturity, or
          may hold the contract to maturity and complete the contemplated
          exchange.

          The following discussion summarizes the Portfolios' principal uses of
          forward foreign currency exchange contracts ("forward currency
          contracts"). A Portfolio may enter into forward currency contracts
          with stated contract values of up to the value of that Portfolio's
          assets. A forward currency contract is an obligation to buy or sell an
          amount of a specified currency for an agreed price (which may be in
          U.S. dollars or a foreign currency). A Portfolio will exchange foreign
          currencies for U.S. dollars and for other foreign currencies in the
          normal course of business and may buy and sell currencies through
          forward currency contracts in order to fix a price for securities it
          has agreed to buy or sell ("transaction hedge"). A Portfolio also may
          hedge some or all of its investments denominated in a foreign currency
          or exposed to foreign currency fluctuations against a decline in the
          value of that currency relative to the U.S. dollar by entering into
          forward currency contracts to sell an amount of that currency (or a
          proxy currency whose performance is expected to replicate or exceed
          the performance of that currency relative to the U.S. dollar)
          approximating the value of some or all of its portfolio securities
          denominated in that currency ("position hedge") or by participating in
          options or futures contracts with respect to the currency. A Portfolio
          also may enter into a forward currency contract with respect to a
          currency where the Portfolio is considering the purchase or sale of
          investments denominated in that currency but has not yet selected the
          specific investments ("anticipatory hedge"). In any of these
          circumstances a Portfolio may, alternatively, enter into a forward
          currency contract to purchase or sell one foreign currency for a
          second currency that is expected to perform more favorably relative to
          the U.S. dollar if the portfolio manager believes there is a
          reasonable degree of correlation between movements in the two
          currencies ("cross-hedge").

          These types of hedging minimize the effect of currency appreciation as
          well as depreciation, but do not eliminate fluctuations in the
          underlying U.S. dollar equivalent value of the proceeds of or rates of
          return on a Portfolio's foreign currency denominated portfolio
          securities. The matching of the increase in value of a forward
          contract and the decline in the U.S. dollar equivalent value of the
          foreign currency denominated asset that is the subject of the hedge
          generally will not be precise. Shifting a Portfolio's currency
          exposure from one foreign currency to another removes that Portfolio's
          opportunity to profit from increases in the value of the original
          currency and involves a risk of increased losses to such Portfolio if
          its portfolio manager's projection of future exchange rates is
          inaccurate. Proxy hedges and cross-hedges may result in losses if the
          currency used to hedge does not perform similarly to the currency in
          which hedged securities are denominated. Unforeseen changes in
          currency prices may result in poorer overall performance for a
          Portfolio than if it had not entered into such contracts.

          The Portfolios will cover outstanding forward currency contracts by
          maintaining liquid portfolio securities denominated in or whose value
          is tied to the currency underlying the forward contract or the
          currency being hedged. To the extent that a Portfolio is not able to
          cover its forward currency positions with underlying portfolio
          securities, the Portfolios' custodian will segregate cash or other
          liquid assets having a value equal to the aggregate amount of such
          Portfolio's commitments under forward contracts entered into with
          respect to position hedges, cross-hedges and anticipatory hedges. If
          the value of the securities used to cover a position or the value of
          segregated assets declines, a Portfolio will find alternative cover or
          segregate additional cash or other liquid assets on a daily basis so
          that the value of the covered and segregated assets will be equal to
          the amount of such Portfolio's commitments with respect to such
          contracts. As an alternative to segregating assets, a Portfolio may
          buy call options permitting such Portfolio

                                                                              15
<PAGE>

          to buy the amount of foreign currency being hedged by a forward sale
          contract or a Portfolio may buy put options permitting it to sell the
          amount of foreign currency subject to a forward buy contract.

          While forward contracts are not currently regulated by the CFTC, the
          CFTC may in the future assert authority to regulate forward contracts.
          In such event, the Portfolios' ability to utilize forward contracts
          may be restricted. In addition, a Portfolio may not always be able to
          enter into forward contracts at attractive prices and may be limited
          in its ability to use these contracts to hedge Portfolio assets.

          OPTIONS ON FOREIGN CURRENCIES. The Portfolios may buy and write
          options on foreign currencies in a manner similar to that in which
          futures or forward contracts on foreign currencies will be utilized.
          For example, a decline in the U.S. dollar value of a foreign currency
          in which portfolio securities are denominated will reduce the U.S.
          dollar value of such securities, even if their value in the foreign
          currency remains constant. In order to protect against such
          diminutions in the value of portfolio securities, a Portfolio may buy
          put options on the foreign currency. If the value of the currency
          declines, such Portfolio will have the right to sell such currency for
          a fixed amount in U.S. dollars, thereby offsetting, in whole or in
          part, the adverse effect on its portfolio.

          Conversely, when a rise in the U.S. dollar value of a currency in
          which securities to be acquired are denominated is projected, thereby
          increasing the cost of such securities, a Portfolio may buy call
          options on the foreign currency. The purchase of such options could
          offset, at least partially, the effects of the adverse movements in
          exchange rates. As in the case of other types of options, however, the
          benefit to a Portfolio from purchases of foreign currency options will
          be reduced by the amount of the premium and related transaction costs.
          In addition, if currency exchange rates do not move in the direction
          or to the extent projected, a Portfolio could sustain losses on
          transactions in foreign currency options that would require such
          Portfolio to forego a portion or all of the benefits of advantageous
          changes in those rates.

          The Portfolios may also write options on foreign currencies. For
          example, to hedge against a potential decline in the U.S. dollar value
          of foreign currency denominated securities due to adverse fluctuations
          in exchange rates, a Portfolio could, instead of purchasing a put
          option, write a call option on the relevant currency. If the expected
          decline occurs, the option will most likely not be exercised and the
          decline in value of portfolio securities will be offset by the amount
          of the premium received.

          Similarly, instead of purchasing a call option to hedge against a
          potential increase in the U.S. dollar cost of securities to be
          acquired, a Portfolio could write a put option on the relevant
          currency which, if rates move in the manner projected, should expire
          unexercised and allow that Portfolio to hedge the increased cost up to
          the amount of the premium. As in the case of other types of options,
          however, the writing of a foreign currency option will constitute only
          a partial hedge up to the amount of the premium. If exchange rates do
          not move in the expected direction, the option may be exercised and a
          Portfolio would be required to buy or sell the underlying currency at
          a loss which may not be offset by the amount of the premium. Through
          the writing of options on foreign currencies, a Portfolio also may
          lose all or a portion of the benefits which might otherwise have been
          obtained from favorable movements in exchange rates.

          The Portfolios may write covered call options on foreign currencies. A
          call option written on a foreign currency by a Portfolio is "covered"
          if that Portfolio owns the foreign currency underlying the call or has
          an absolute and immediate right to acquire that foreign currency
          without additional cash consideration (or for additional cash
          consideration held in a segregated account by its custodian) upon
          conversion or exchange of other foreign currencies held in its
          portfolio. A call option is also covered if a Portfolio has a call on
          the same foreign currency in the same principal amount as the call
          written if the exercise price of the call held (i) is equal to or less
          than the exercise price of the call written or (ii) is greater than
          the

          exercise price of the call written, if the difference is maintained by
          such Portfolio in cash or other liquid assets in a segregated account
          with the Portfolios' custodian.

          The Portfolios also may write call options on foreign currencies for
          cross-hedging purposes. A call option on a foreign currency is for
          cross-hedging purposes if it is designed to provide a hedge against a
          decline due to an adverse change in the exchange rate in the U.S.
          dollar value of a security which a Portfolio owns or has the right to
          acquire and which is denominated in the currency underlying the
          option. Call options on foreign currencies which are entered into for
          cross-hedging purposes are not covered. However, in such
          circumstances, a Portfolio will collateralize the option by
          segregating cash or other liquid assets in an amount not less than the
          value of the underlying foreign currency in U.S. dollars
          marked-to-market daily.

          OPTIONS ON SECURITIES. In an effort to increase current income and to
          reduce fluctuations in net asset value, the Portfolios may write
          covered put and call options and buy put and call options on
          securities that are traded on United States and foreign securities
          exchanges and over-the-counter. The Portfolios may write and buy
          options on the same types of securities that the Portfolios may
          purchase directly.

          A put option written by a Portfolio is "covered" if that Portfolio (i)
          segregates cash not available for investment or other liquid assets
          with a value equal to the exercise price of the put with the
          Portfolios' custodian or (ii) holds a put on the same security and in
          the same principal amount as the put written and the exercise price of
          the put held is equal to or greater than the exercise price of the put
          written. The premium paid by the buyer of an option will reflect,
          among other things, the relationship of the exercise price to the
          market price and the volatility of the underlying security, the
          remaining term of the option, supply and demand and interest rates.

          A call option written by a Portfolio is "covered" if that Portfolio
          owns the underlying security covered by the call or has an absolute
          and immediate right to acquire that security without additional cash
          consideration (or for additional cash consideration held in a
          segregated account by the Portfolios' custodian) upon conversion or
          exchange of other securities held in its portfolio. A call option is
          also deemed to be covered if a Portfolio holds a call on the same
          security and in the same principal amount as the call written and the
          exercise price of the call held (i) is equal to or less than the
          exercise price of the call written or (ii) is greater than the
          exercise price of the call written if the difference is maintained by
          that Portfolio in cash and other liquid assets in a segregated account
          with its custodian.

          The Portfolios also may write call options that are not covered for
          cross-hedging purposes. A Portfolio collateralizes its obligation
          under a written call option for cross-hedging purposes by segregating
          cash or other liquid assets in an amount not less than the market
          value of the underlying security, marked-to-market daily. A Portfolio
          would write a call option for cross-hedging purposes, instead of
          writing a covered call option, when the premium to be received from
          the cross-hedge transaction would exceed that which would be received
          from writing a covered call option and its portfolio manager believes
          that writing the option would achieve the desired hedge.

          The writer of an option may have no control over when the underlying
          securities must be sold, in the case of a call option, or bought, in
          the case of a put option, since with regard to certain options, the
          writer may be assigned an exercise notice at any time prior to the
          termination of the obligation. Whether or not an option expires
          unexercised, the writer retains the amount of the premium. This
          amount, of course, may, in the case of a covered call option, be
          offset by a decline in the market value of the underlying security
          during the option period. If a call option is exercised, the writer
          experiences a profit or loss from the sale of the underlying security.
          If a put option is exercised, the writer must fulfill the obligation
          to buy the

                                                                              17
<PAGE>

          underlying security at the exercise price, which will usually exceed
          the then market value of the underlying security.

          The writer of an option that wishes to terminate its obligation may
          effect a "closing purchase transaction." This is accomplished by
          buying an option of the same series as the option previously written.
          The effect of the purchase is that the writer's position will be
          canceled by the clearing corporation. However, a writer may not effect
          a closing purchase transaction after being notified of the exercise of
          an option. Likewise, an investor who is the holder of an option may
          liquidate its position by effecting a "closing sale transaction." This
          is accomplished by selling an option of the same series as the option
          previously bought. There is no guarantee that either a closing
          purchase or a closing sale transaction can be effected.

          In the case of a written call option, effecting a closing transaction
          will permit a Portfolio to write another call option on the underlying
          security with either a different exercise price or expiration date or
          both. In the case of a written put option, such transaction will
          permit a Portfolio to write another put option to the extent that the
          exercise price is secured by deposited liquid assets. Effecting a
          closing transaction also will permit a Portfolio to use the cash or
          proceeds from the concurrent sale of any securities subject to the
          option for other investments. If a Portfolio desires to sell a
          particular security from its portfolio on which it has written a call
          option, such Portfolio will effect a closing transaction prior to or
          concurrent with the sale of the security.

          A Portfolio will realize a profit from a closing transaction if the
          price of the purchase transaction is less than the premium received
          from writing the option or the price received from a sale transaction
          is more than the premium paid to buy the option. A Portfolio will
          realize a loss from a closing transaction if the price of the purchase
          transaction is more than the premium received from writing the option
          or the price received from a sale transaction is less than the premium
          paid to buy the option. Because increases in the market of a call
          option generally will reflect increases in the market price of the
          underlying security, any loss resulting from the repurchase of a call
          option is likely to be offset in whole or in part by appreciation of
          the underlying security owned by a Portfolio.

          An option position may be closed out only where a secondary market for
          an option of the same series exists. If a secondary market does not
          exist, the Portfolio may not be able to effect closing transactions in
          particular options and the Portfolio would have to exercise the
          options in order to realize any profit. If a Portfolio is unable to
          effect a closing purchase transaction in a secondary market, it will
          not be able to sell the underlying security until the option expires
          or it delivers the underlying security upon exercise. The absence of a
          liquid secondary market may be due to the following: (i) insufficient
          trading interest in certain options, (ii) restrictions imposed by a
          national securities exchange ("Exchange") on which the option is
          traded on opening or closing transactions or both, (iii) trading
          halts, suspensions or other restrictions imposed with respect to
          particular classes or series of options or underlying securities, (iv)
          unusual or unforeseen circumstances that interrupt normal operations
          on an Exchange, (v) the facilities of an Exchange or of the Options
          Clearing Corporation ("OCC") may not at all times be adequate to
          handle current trading volume, or (vi) one or more Exchanges could,
          for economic or other reasons, decide or be compelled at some future
          date to discontinue the trading of options (or a particular class or
          series of options), in which event the secondary market on that
          Exchange (or in that class or series of options) would cease to exist,
          although outstanding options on that Exchange that had been issued by
          the OCC as a result of trades on that Exchange would continue to be
          exercisable in accordance with their terms.

          A Portfolio may write options in connection with buy-and-write
          transactions. In other words, a Portfolio may buy a security and then
          write a call option against that security. The exercise price of such
          call will

 18
<PAGE>

          depend upon the expected price movement of the underlying security.
          The exercise price of a call option may be below ("in-the-money"),
          equal to ("at-the-money") or above ("out-of-the-money") the current
          value of the underlying security at the time the option is written.
          Buy-and-write transactions using in-the-money call options may be used
          when it is expected that the price of the underlying security will
          remain flat or decline moderately during the option period.
          Buy-and-write transactions using at-the-money call options may be used
          when it is expected that the price of the underlying security will
          remain fixed or advance moderately during the option period.
          Buy-and-write transactions using out-of-the-money call options may be
          used when it is expected that the premiums received from writing the
          call option plus the appreciation in the market price of the
          underlying security up to the exercise price will be greater than the
          appreciation in the price of the underlying security alone. If the
          call options are exercised in such transactions, a Portfolio's maximum
          gain will be the premium received by it for writing the option,
          adjusted upwards or downwards by the difference between that
          Portfolio's purchase price of the security and the exercise price. If
          the options are not exercised and the price of the underlying security
          declines, the amount of such decline will be offset by the amount of
          premium received.

          The writing of covered put options is similar in terms of risk and
          return characteristics to buy-and-write transactions. If the market
          price of the underlying security rises or otherwise is above the
          exercise price, the put option will expire worthless and a Portfolio's
          gain will be limited to the premium received. If the market price of
          the underlying security declines or otherwise is below the exercise
          price, a Portfolio may elect to close the position or take delivery of
          the security at the exercise price and that Portfolio's return will be
          the premium received from the put options minus the amount by which
          the market price of the security is below the exercise price.

          A Portfolio may buy put options to hedge against a decline in the
          value of its portfolio. By using put options in this way, a Portfolio
          will reduce any profit it might otherwise have realized in the
          underlying security by the amount of the premium paid for the put
          option and by transaction costs.

          A Portfolio may buy call options to hedge against an increase in the
          price of securities that it may buy in the future. The premium paid
          for the call option plus any transaction costs will reduce the
          benefit, if any, realized by such Portfolio upon exercise of the
          option, and, unless the price of the underlying security rises
          sufficiently, the option may expire worthless to that Portfolio.

          EURODOLLAR INSTRUMENTS. A Portfolio may make investments in Eurodollar
          instruments. Eurodollar instruments are U.S. dollar-denominated
          futures contracts or options thereon which are linked to the London
          Interbank Offered Rate ("LIBOR"), although foreign
          currency-denominated instruments are available from time to time.
          Eurodollar futures contracts enable purchasers to obtain a fixed rate
          for the lending of funds and sellers to obtain a fixed rate for
          borrowings. A Portfolio might use Eurodollar futures contracts and
          options thereon to hedge against changes in LIBOR, to which many
          interest rate swaps and fixed-income instruments are linked.

          SWAPS AND SWAP-RELATED PRODUCTS. A Portfolio may enter into interest
          rate swaps, caps and floors on either an asset-based or
          liability-based basis, depending upon whether it is hedging its assets
          or its liabilities, and will usually enter into interest rate swaps on
          a net basis (i.e., the two payment streams are netted out, with a
          Portfolio receiving or paying, as the case may be, only the net amount
          of the two payments). The net amount of the excess, if any, of a
          Portfolio's obligations over its entitlement with respect to each
          interest rate swap will be calculated on a daily basis and an amount
          of cash or other liquid assets having an aggregate net asset value at
          least equal to the accrued excess will be maintained in a segregated
          account by the Portfolios' custodian. If a Portfolio enters into an
          interest rate swap on other

                                                                              19
<PAGE>

          than a net basis, it would maintain a segregated account in the full
          amount accrued on a daily basis of its obligations with respect to the
          swap. A Portfolio will not enter into any interest rate swap, cap or
          floor transaction unless the unsecured senior debt or the
          claims-paying ability of the other party thereto is rated in one of
          the three highest rating categories of at least one NRSRO at the time
          of entering into such transaction. Janus Capital will monitor the
          creditworthiness of all counterparties on an ongoing basis. If there
          is a default by the other party to such a transaction, a Portfolio
          will have contractual remedies pursuant to the agreements related to
          the transaction.

          The swap market has grown substantially in recent years with a large
          number of banks and investment banking firms acting both as principals
          and as agents utilizing standardized swap documentation. Janus Capital
          has determined that, as a result, the swap market has become
          relatively liquid. Caps and floors are more recent innovations for
          which standardized documentation has not yet been developed and,
          accordingly, they are less liquid than swaps. To the extent a
          Portfolio sells (i.e., writes) caps and floors, it will segregate cash
          or other liquid assets having an aggregate net asset value at least
          equal to the full amount, accrued on a daily basis, of its obligations
          with respect to any caps or floors.

          There is no limit on the amount of interest rate swap transactions
          that may be entered into by a Portfolio. These transactions may in
          some instances involve the delivery of securities or other underlying
          assets by a Portfolio or its counterparty to collateralize obligations
          under the swap. Under the documentation currently used in those
          markets, the risk of loss with respect to interest rate swaps is
          limited to the net amount of the payments that a Portfolio is
          contractually obligated to make. If the other party to an interest
          rate swap that is not collateralized defaults, a Portfolio would risk
          the loss of the net amount of the payments that it contractually is
          entitled to receive. A Portfolio may buy and sell (i.e., write) caps
          and floors without limitation, subject to the segregation requirement
          described above.

          ADDITIONAL RISKS OF OPTIONS ON FOREIGN CURRENCIES, FORWARD CONTRACTS
          AND FOREIGN INSTRUMENTS. Unlike transactions entered into by the
          Portfolios in futures contracts, options on foreign currencies and
          forward contracts are not traded on contract markets regulated by the
          CFTC or (with the exception of certain foreign currency options) by
          the SEC. To the contrary, such instruments are traded through
          financial institutions acting as market-makers, although foreign
          currency options are also traded on certain Exchanges, such as the
          Philadelphia Stock Exchange and the Chicago Board Options Exchange,
          subject to SEC regulation. Similarly, options on currencies may be
          traded over-the-counter. In an over-the-counter trading environment,
          many of the protections afforded to Exchange participants will not be
          available. For example, there are no daily price fluctuation limits,
          and adverse market movements could therefore continue to an unlimited
          extent over a period of time. Although the buyer of an option cannot
          lose more than the amount of the premium plus related transaction
          costs, this entire amount could be lost. Moreover, an option writer
          and a buyer or seller of futures or forward contracts could lose
          amounts substantially in excess of any premium received or initial
          margin or collateral posted due to the potential additional margin and
          collateral requirements associated with such positions.

          Options on foreign currencies traded on Exchanges are within the
          jurisdiction of the SEC, as are other securities traded on Exchanges.
          As a result, many of the protections provided to traders on organized
          Exchanges will be available with respect to such transactions. In
          particular, all foreign currency option positions entered into on an
          Exchange are cleared and guaranteed by the OCC, thereby reducing the
          risk of counterparty default. Further, a liquid secondary market in
          options traded on an Exchange may be more readily available than in
          the over-the-counter market, potentially permitting a Portfolio to
          liquidate open positions at a profit prior to exercise or expiration,
          or to limit losses in the event of adverse market movements.

<PAGE>

          The purchase and sale of exchange-traded foreign currency options,
          however, is subject to the risks of the availability of a liquid
          secondary market described above, as well as the risks regarding
          adverse market movements, margining of options written, the nature of
          the foreign currency market, possible intervention by governmental
          authorities and the effects of other political and economic events. In
          addition, exchange-traded options on foreign currencies involve
          certain risks not presented by the over-the-counter market. For
          example, exercise and settlement of such options must be made
          exclusively through the OCC, which has established banking
          relationships in applicable foreign countries for this purpose. As a
          result, the OCC may, if it determines that foreign governmental
          restrictions or taxes would prevent the orderly settlement of foreign
          currency option exercises, or would result in undue burdens on the OCC
          or its clearing member, impose special procedures on exercise and
          settlement, such as technical changes in the mechanics of delivery of
          currency, the fixing of dollar settlement prices or prohibitions on
          exercise.

          In addition, options on U.S. government securities, futures contracts,
          options on futures contracts, forward contracts and options on foreign
          currencies may be traded on foreign exchanges and over-the-counter in
          foreign countries. Such transactions are subject to the risk of
          governmental actions affecting trading in or the prices of foreign
          currencies or securities. The value of such positions also could be
          adversely affected by (i) other complex foreign political and economic
          factors, (ii) lesser availability than in the United States of data on
          which to make trading decisions, (iii) delays in a Portfolio's ability
          to act upon economic events occurring in foreign markets during
          non-business hours in the United States, (iv) the imposition of
          different exercise and settlement terms and procedures and margin
          requirements than in the United States, and (v) low trading volume.

                                                                              21

Investment adviser

          As stated in the Prospectus, each Portfolio has an Investment Advisory
          Agreement with Janus Capital, 100 Fillmore Street, Denver, Colorado
          80206-4928. Each Advisory Agreement provides that Janus Capital will
          furnish continuous advice and recommendations concerning the
          Portfolios' investments, provide office space for the Portfolios, and
          pay the salaries, fees and expenses of all Portfolio officers and of
          those Trustees who are affiliated with Janus Capital. Janus Capital
          also may make payments to selected broker-dealer firms or institutions
          which were instrumental in the acquisition of shareholders for the
          Portfolios or other Janus Funds or which perform recordkeeping or
          other services with respect to shareholder accounts. The minimum
          aggregate size required for eligibility for such payments, and the
          factors in selecting the broker-dealer firms and institutions to which
          they will be made, are determined from time to time by Janus Capital.
          Janus Capital is also authorized to perform the management and
          administrative services necessary for the operation of the Portfolios.

          The Portfolios pay custodian and transfer agent fees and expenses,
          brokerage commissions and dealer spreads and other expenses in
          connection with the execution of portfolio transactions, legal and
          accounting expenses, interest and taxes, registration fees, expenses
          of shareholders' meetings and reports to shareholders, fees and
          expenses of Portfolio Trustees who are not affiliated with Janus
          Capital and other costs of complying with applicable laws regulating
          the sale of Portfolio shares. Pursuant to the Advisory Agreements,
          Janus Capital furnishes certain other services, including net asset
          value determination, portfolio accounting and recordkeeping, for which
          the Portfolios may reimburse Janus Capital for its costs.


          Growth Portfolio, Aggressive Growth Portfolio, Capital Appreciation
          Portfolio, Balanced Portfolio, Equity Income Portfolio, Growth and
          Income Portfolio, International Growth Portfolio, Worldwide Growth
          Portfolio, Global Life Sciences Portfolio and Global Technology
          Portfolio have each agreed to compensate Janus Capital for its
          services by the monthly payment of a fee at the annual rate of 0.65%
          of the average daily net assets of each Portfolio. This fee is the
          same or lower than the fee that each of the Equity Portfolios paid
          under its old agreement during its most recent fiscal year.



          Janus Capital has agreed to reimburse Equity Income Portfolio, Global
          Life Sciences Portfolio and Global Technology Portfolio by the amount,
          if any, that such Portfolio's normal operating expenses in any fiscal
          year, including the investment advisory fee but excluding brokerage
          commissions, interest, taxes and extraordinary expenses, exceed an
          annual rate of 1.25% of the average daily net assets of the Portfolio
          until at least the next annual renewal of the advisory agreements.
          Mortality risk, expense risk and other charges imposed by
          participating insurance companies are excluded from the above expense
          limitation.



          High-Yield Portfolio has agreed to compensate Janus Capital for its
          services by the monthly payment of a fee at the annual rate of .75% of
          the first $300 million of average daily net assets of the Portfolio
          and .65% of the average daily net assets in excess of $300 million.
          Flexible Income Portfolio has agreed to compensate Janus Capital for
          its services by the monthly payment of a fee at the annual rate of
          .65% of the first $300 million of the average daily net assets of the
          Portfolio, plus .55% of the average daily net assets of the Portfolio
          in excess of $300 million. Janus Capital has agreed to waive the
          advisory fee payable of High-Yield Portfolio and Flexible Income
          Portfolio in an amount equal to the amount, if any, that the
          Portfolio's normal operating expenses in any fiscal year, including
          the investment advisory fee but excluding brokerage commissions,
          interest, taxes and extraordinary expenses, exceed 1% of the average
          daily net assets for a fiscal year. Mortality risk, expense risk and
          other charges imposed by participating insurance companies are
          excluded from the above expense limitation. Janus Capital has agreed
          to continue such waivers until at least the next annual renewal of the
          advisory agreements.

          The following table summarizes the advisory fees paid by the
          Portfolios and any advisory fee waivers for the periods indicated. The
          information below is for fiscal years ended December 31. The
          information presented in the table below reflects the management fees
          in effect during each of the periods shown. Effective May 1, 2000, the
          Equity Portfolios' management fees were changed to 0.65% of the
          average daily net assets of each Portfolio. This fee is the same as or
          lower than the fee that each Equity Portfolio paid under its old
          agreement.

(1) In addition to these fee waivers, Janus Capital has agreed to reduce the
    advisory fee of the Growth, Aggressive Growth, Capital Appreciation,
    Balanced, Equity Income, Growth and Income Portfolios, International Growth
    and Worldwide Growth to the extent that such fee exceeds the effective rate
    of the Janus retail fund corresponding to such Portfolio.
(2) May 1, 1997 (inception) to December 31, 1997.
(3) Fee waiver by Janus Capital exceeded the advisory fee.
(4) May 1, 1998 (inception) to December 31, 1998.

(5) The Portfolio had not commenced operations as of December 31, 1999.



          The Advisory Agreement for each of the Portfolios is dated July 1,
          1997 (except Global Life Sciences Portfolio and Global Technology
          Portfolio, which are dated December 14, 1999). The Equity Portfolios'
          Advisory Agreements were each amended effective May 1, 2000 to
          decrease the management fees. Each Advisory Agreement will continue in
          effect until July 1, 2001, and thereafter from year to year so long as
          such continuance is approved annually by a majority of the Portfolios'
          Trustees who are not parties to the Advisory Agreements or interested
          persons of any such party, and by either a majority of the outstanding
          voting shares or the Trustees of the Portfolios. Each Advisory
          Agreement (i) may be terminated without the payment of any penalty by
          any Portfolio or Janus Capital on 60 days' written notice; (ii)
          terminates automatically in the event of its assignment; and (iii)
          generally, may not be amended without the approval by vote of a
          majority of the Trustees of the affected Portfolio, including the
          Trustees who are not interested persons of that Portfolio or Janus
          Capital and, to the extent required by the 1940 Act, the vote of a
          majority of the outstanding voting securities of that Portfolio.


          Janus Capital acts as sub-adviser for a number of private-label mutual
          funds and provides separate account advisor services for institutional
          accounts. Investment decisions for each account managed by Janus
          Capital, including the Portfolios, are made independently from those
          for any other account that is or may in the future become managed by
          Janus Capital or its affiliates. If, however, a number of accounts
          managed by Janus Capital are contemporaneously engaged in the purchase
          or sale of the same security, the orders may be aggregated and/or the
          transactions may be averaged as to price and allocated equitably to
          each account. In some cases, this policy might adversely affect the
          price paid or received by an account or

                                                                              23

          the size of the position obtained or liquidated for an account.
          Pursuant to an exemptive order granted by the SEC, the Portfolios and
          other portfolios advised by Janus Capital may also transfer daily
          uninvested cash balances into one or more joint trading accounts.
          Assets in the joint trading accounts are invested in money market
          instruments and the proceeds are allocated to the participating
          portfolios on a pro rata basis.


          Kansas City Southern Industries, Inc. ("KCSI"), indirectly through its
          wholly owned subsidiary, Stilwell Financial Inc., owns approximately
          81% of the outstanding voting stock of Janus Capital. KCSI is a
          publicly traded holding company whose primary subsidiaries are engaged
          in transportation, information processing and financial services.
          Thomas H. Bailey, President and Chairman of the Board of Janus
          Capital, owns approximately 12% of Janus Capital's voting stock and,
          by agreement with KCSI, selects at least a majority of Janus Capital's
          Board, subject to the approval of Stilwell Financial, which cannot be
          unreasonably withheld.



          KCSI has announced its intention to separate its transportation and
          financial services businesses. KCSI anticipates the separation to be
          completed in the first half of 2000.


          Each account managed by Janus Capital has its own investment objective
          and policies and is managed accordingly by a particular portfolio
          manager or team of portfolio managers. As a result, from time to time
          two or more different managed accounts may pursue divergent investment
          strategies with respect to investments or categories of investments.


          Janus Capital does not permit the Portfolios' portfolio managers to
          purchase and sell securities for their own accounts except under the
          limited exceptions contained in the Portfolios' Code of Ethics
          ("Code"). The Portfolios' Code of Ethics is on file with and available
          through the SEC Web site at www.sec.gov. The Code applies to
          Directors/Trustees of Janus Capital and the Portfolios, and employees
          of Janus Capital and the Trust, and requires investment personnel,
          inside Directors/Trustees of Janus Capital and the Portfolios and
          certain other designated employees deemed to have access to current
          trading information to pre-clear all transactions in securities not
          otherwise exempt under the Code. Requests for trading authorization
          will be denied when, among other reasons, the proposed personal
          transaction would be contrary to the provisions of the Code or would
          be deemed to adversely affect any transaction then known to be under
          consideration for or to have been effected on behalf of any client
          account, including the Portfolios.



          In addition to the pre-clearance requirement described above, the Code
          subjects such personnel to various trading restrictions and reporting
          obligations. All reportable transactions are required to be reviewed
          for compliance with the Code. Those persons also may be required under
          certain circumstances to forfeit their profits made from personal
          trading.



          The provisions of the Code are administered by and subject to
          exceptions authorized by Janus Capital.

Custodian, transfer agent and certain affiliations

          State Street Bank and Trust Company, P.O. Box 0351, Boston,
          Massachusetts 02117-0351 is the custodian of the domestic securities
          and cash of the Portfolios. State Street and the foreign subcustodians
          it selects, have custody of the assets of the Portfolios held outside
          the U.S. and cash incidental thereto. The custodians and subcustodians
          hold the Portfolios' assets in safekeeping and collect and remit the
          income thereon, subject to the instructions of each Portfolio.

          Janus Service Corporation, P.O. Box 173375, Denver, Colorado
          80217-3375, a wholly-owned subsidiary of Janus Capital, is the
          Portfolios' transfer agent. In addition, Janus Service provides
          certain other administrative, recordkeeping and shareholder relations
          services to the Portfolios. Janus Service is not compensated for its
          services related to the Shares, except for out-of-pocket costs.


          The Portfolios pay DST Systems, Inc., a subsidiary of KCSI, license
          fees at the annual rate of $3.06 per shareholder account for the
          equity portfolios and $3.98 per shareholder account for the
          fixed-income portfolios for the use of DST's shareholder accounting
          system. The Portfolios also pay DST $1.10 per closed shareholder
          account. The Portfolios pay DST for the use of its portfolio and fund
          accounting system a monthly base fee of $250 to $1,250 per month based
          on the number of Janus funds using the system and an asset charge of
          $1 per million dollars of net assets (not to exceed $500 per month).


          The Trustees have authorized the Portfolios to use another affiliate
          of DST as introducing broker for certain Portfolio transactions as a
          means to reduce Portfolio expenses through credits against the charges
          of DST and its affiliates with regard to commissions earned by such
          affiliate. DST charges shown above are net of such credits. See
          "Portfolio Transactions and Brokerage."

          Janus Distributors, Inc., 100 Fillmore Street, Denver, Colorado
          80206-4928, a wholly-owned subsidiary of Janus Capital, is a
          distributor of the Portfolios. Janus Distributors is registered as a
          broker-dealer under the Securities Exchange Act of 1934 and is a
          member of the National Association of Securities Dealers, Inc.

                                                                              25

Portfolio transactions and brokerage

          Decisions as to the assignment of portfolio business for the
          Portfolios and negotiation of its commission rates are made by Janus
          Capital whose policy is to obtain the "best execution" (prompt and
          reliable execution at the most favorable security price) of all
          portfolio transactions. The Portfolios may trade foreign securities in
          foreign countries because the best available market for these
          securities is often on foreign exchanges. In transactions on foreign
          stock exchanges, brokers' commissions are frequently fixed and are
          often higher than in the United States, where commissions are
          negotiated.

          In selecting brokers and dealers and in negotiating commissions, Janus
          Capital considers a number of factors, including but not limited to:
          Janus Capital's knowledge of currently available negotiated commission
          rates or prices of securities currently available and other current
          transaction costs; the nature of the security being traded; the size
          and type of the transaction; the nature and character of the markets
          for the security to be purchased or sold; the desired timing of the
          trade; the activity existing and expected in the market for the
          particular security; confidentiality; the quality of the execution,
          clearance and settlement services; financial stability of the broker
          or dealer; the existence of actual or apparent operational problems of
          any broker or dealer; rebates of commissions by a broker to a
          Portfolio or to a third party service provider to the Portfolio to pay
          Portfolio expenses; and research products or services provided. In
          recognition of the value of the foregoing factors, Janus Capital may
          place portfolio transactions with a broker or dealer with whom it has
          negotiated a commission that is in excess of the commission another
          broker or dealer would have charged for effecting that transaction if
          Janus Capital determines in good faith that such amount of commission
          was reasonable in relation to the value of the brokerage and research
          provided by such broker or dealer viewed in terms of either that
          particular transaction or of the overall responsibilities of Janus
          Capital. Research may include furnishing advice, either directly or
          through publications or writings, as to the value of securities, the
          advisability of purchasing or selling specific securities and the
          availability of securities or purchasers or sellers of securities;
          furnishing seminars, information, analyses and reports concerning
          issuers, industries, securities, trading markets and methods,
          legislative developments, changes in accounting practices, economic
          factors and trends and portfolio strategy; access to research
          analysts, corporate management personnel, industry experts, economists
          and government officials; comparative performance evaluation and
          technical measurement services and quotation services, and products
          and other services (such as third party publications, reports and
          analyses, and computer and electronic access, equipment, software,
          information and accessories that deliver, process or otherwise utilize
          information, including the research described above) that assist Janus
          Capital in carrying out its responsibilities. Research received from
          brokers or dealers is supplemental to Janus Capital's own research
          efforts. Most brokers and dealers used by Janus Capital provide
          research and other services described above.

          For the year ended December 31, 1999, the total brokerage commissions
          paid by the Portfolios to brokers and dealers in transactions
          identified for execution primarily on the basis of research and other
          services provided to the Portfolios are summarized below:

Note: Portfolios that are not included in the table did not pay any commissions
      related to research for the stated period.

          Janus Capital may use research products and services in servicing
          other accounts in addition to the Portfolios. If Janus Capital
          determines that any research product or service has a mixed use, such
          that it also serves functions that do not assist in the investment
          decision-making process, Janus Capital may allocate the costs of such
          service or product accordingly. Only that portion of the product or
          service that Janus Capital determines will assist it in the investment
          decision-making process may be paid for in brokerage commission
          dollars. Such allocation may create a conflict of interest for Janus
          Capital.

          Janus Capital does not enter into agreements with any brokers
          regarding the placement of securities transactions because of the
          research services they provide. It does, however, have an internal
          procedure for allocating transactions in a manner consistent with its
          execution policy to brokers that it has identified as providing
          superior executions and research, research-related products or
          services which benefit its advisory clients, including the Portfolios.
          Research products and services incidental to effecting securities
          transactions furnished by brokers or dealers may be used in servicing
          any or all of Janus Capital's clients and such research may not
          necessarily be used by Janus Capital in connection with the accounts
          which paid commissions to the broker-dealer providing such research
          products and services.

          Janus Capital may consider sales of Portfolio Shares or shares of
          other Janus funds by a broker-dealer or the recommendation of a
          broker-dealer to its customers that they purchase Portfolio Shares as
          a factor in the selection of broker-dealers to execute Portfolio
          transactions. Janus Capital may also consider payments made by brokers
          effecting transactions for a Portfolio (i) to the Portfolio or (ii) to
          other persons on behalf of the Portfolio for services provided to the
          Portfolio for which it would be obligated to pay. In placing Portfolio
          business with such broker-dealers, Janus Capital will seek the best
          execution of each transaction.

          When the Portfolios purchase or sell a security in the
          over-the-counter market, the transaction takes place directly with a
          principal market-maker, without the use of a broker, except in those
          circumstances where in the opinion of Janus Capital better prices and
          executions will be achieved through the use of a broker.

          The Portfolios' Trustees have authorized Janus Capital to place
          transactions with DST Securities, Inc. ("DSTS"), a wholly-owned
          broker-dealer subsidiary of DST. Janus Capital may do so if it
          reasonably believes that the quality of the transaction and the
          associated commission are fair and reasonable and if, overall, the
          associated transaction costs, net of any credits described above under
          "Custodian, Transfer Agent and Certain Affiliations," are lower than
          those that would otherwise be incurred.

                                                                              27

Note: Portfolios that are not included in the table did not pay brokerage
      commissions because securities transactions for such Portfolios involved
      dealers acting as principals.


          Included in such brokerage commissions are the following amounts paid
          to DSTS, which served to reduce each Portfolio's out-of-pocket
          expenses as follows:

* The difference between commissions paid to DSTS and expenses reduced
  constitute commissions paid to an unaffiliated clearing broker.
+ Differences in the percentage of total commissions versus the percentage of
  total transactions are due, in part, to variations among share prices and
  number of shares traded, while average price per share commission rates were
  substantially the same.

Note: Portfolios that did not execute trades with DSTS during the periods
      indicated are not included in the table.

Shares of the trust

NET ASSET VALUE DETERMINATION

          As stated in the Prospectus, the net asset value ("NAV") of the Shares
          of each Portfolio is determined once each day on which the NYSE is
          open, at the close of its regular trading session (normally 4:00 p.m.,
          New York time, Monday through Friday). The NAV of the Shares of each
          Portfolio is not determined on days the NYSE is closed (generally, New
          Year's Day, Martin Luther King Day, Presidents' Day, Good Friday,
          Memorial Day, Independence Day, Labor Day, Thanksgiving and
          Christmas). The per Share NAV of the Shares of each Portfolio is
          determined by dividing the total value of a Portfolio's securities and
          other assets, less liabilities, attributable to the Shares of a
          Portfolio, by the total number of Shares outstanding. In determining
          NAV, securities listed on an Exchange, the NASDAQ National Market and
          foreign markets are valued at the closing prices on such markets, or
          if such price is lacking for the trading period immediately preceding
          the time of determination, such securities are valued at their current
          bid price. Municipal securities held by the Portfolios are traded
          primarily in the over-the-counter market. Valuations of such
          securities are furnished by one or more pricing services employed by
          the Portfolios and are based upon last trade or closing sales prices
          or a computerized matrix system or appraisals obtained by a pricing
          service, in each case in reliance upon information concerning market
          transactions and quotations from recognized municipal securities
          dealers. Other securities that are traded on the over-the-counter
          market are valued at their closing bid prices. Foreign securities and
          currencies are converted to U.S. dollars using the exchange rate in
          effect at the close of the NYSE. Each Portfolio will determine the
          market value of individual securities held by it, by using prices
          provided by one or more professional pricing services which may
          provide market prices to other funds, or, as needed, by obtaining
          market quotations from independent broker-dealers. Short-term
          securities maturing within 60 days are valued on an amortized cost
          basis. Securities for which quotations are not readily available, and
          other assets, are valued at fair values determined in good faith under
          procedures established by and under the supervision of the Trustees.

          Trading in securities on European and Far Eastern securities exchanges
          and over-the-counter markets is normally completed well before the
          close of business on each business day in New York (i.e., a day on
          which the NYSE is open). In addition, European or Far Eastern
          securities trading generally or in a particular country or countries
          may not take place on all business days in New York. Furthermore,
          trading takes place in Japanese markets on certain Saturdays and in
          various foreign markets on days which are not business days in New
          York and on which a Portfolio's NAV is not calculated. A Portfolio
          calculates its NAV per Share, and therefore effects sales, redemptions
          and repurchases of its Shares, as of the close of the NYSE once on
          each day on which the NYSE is open. Such calculation may not take
          place contemporaneously with the determination of the prices of the
          foreign portfolio securities used in such calculation.

PURCHASES

          Shares of the Portfolios can be purchased only by (i) the separate
          accounts of participating insurance companies for the purpose of
          funding variable insurance contracts and (ii) certain qualified
          retirement plans. Participating insurance companies and certain other
          designated organizations are authorized to receive purchase orders on
          the Portfolios' behalf and those organizations are authorized to
          designate their agents and affiliates as intermediaries to receive
          purchase orders. Purchase orders are deemed received by a Portfolio
          when authorized organizations, their agents or affiliates receive the
          order. The Portfolios are not responsible for the failure of any
          designated organization or its agents or affiliates to carry out its
          obligations to its customers. Shares of the Portfolios are purchased
          at the NAV per Share as determined at the close of the regular trading
          session of the NYSE next occurring after a purchase order is received
          and accepted by a Portfolio or its authorized agent. In order to
          receive a day's price, your order must be received by the close of the
          regular trading session of the NYSE as described above in "Net Asset
          Value

                                                                              35

          Determination." The prospectus for your insurance company's separate
          account or your plan documents contain detailed information about
          investing in the different Portfolios.

REDEMPTIONS


          Redemptions, like purchases, may only be effected through the separate
          accounts of participating insurance companies or qualified retirement
          plans. Certain designated organizations are authorized to receive
          redemption orders on the Portfolios' behalf and those organizations
          are authorized to designate their agents and affiliates as
          intermediaries to receive redemption orders. Redemption orders are
          deemed received by a Portfolio when authorized organizations, their
          agents or affiliates receive the order. The Portfolios are not
          responsible for the failure of any designated organization or its
          agents or affiliates to carry out its obligations to its customers.
          Shares normally will be redeemed for cash, although each Portfolio
          retains the right to redeem some or all of its Shares in kind under
          unusual circumstances, in order to protect the interests of remaining
          shareholders, or to accommodate a request by a particular shareholder
          that does not adversely affect the interest of the remaining
          shareholders, by delivery of securities selected from its assets at
          its discretion. However, the Portfolios are governed by Rule 18f-1
          under the 1940 Act, which requires each Portfolio to redeem shares
          solely in cash up to the lesser of $250,000 or 1% of the NAV of that
          Portfolio during any 90-day period for any one shareholder. Should
          redemptions by any shareholder exceed such limitation, a Portfolio
          will have the option of redeeming the excess in cash or in kind. If
          shares are redeemed in kind, the redeeming shareholder might incur
          brokerage costs in converting the assets to cash. The method of
          valuing securities used to make redemptions in kind will be the same
          as the method of valuing portfolio securities described under "Shares
          of the Trust - Net Asset Value Determination" and such valuation will
          be made as of the same time the redemption price is determined.


          The right to require the Portfolios to redeem their shares may be
          suspended, or the date of payment may be postponed, whenever (1)
          trading on the NYSE is restricted, as determined by the SEC, or the
          NYSE is closed except for holidays and weekends, (2) the SEC permits
          such suspension and so orders, or (3) an emergency exists as
          determined by the SEC so that disposal of securities or determination
          of NAV is not reasonably practicable.

Income dividends, capital gains distributions and tax
       status


          It is a policy of the Shares of the Portfolios to make distributions
          of substantially all of their respective investment income and any net
          realized capital gains. The Portfolios intend to qualify as regulated
          investment companies by satisfying certain requirements prescribed by
          Subchapter M of the Internal Revenue Code ("Code"). In addition, each
          Portfolio intends to comply with the diversification requirements of
          Code Section 817(h) related to the tax-deferred status of insurance
          company separate accounts.


          All income dividends and capital gains distributions, if any, on a
          Portfolio's Shares are reinvested automatically in additional Shares
          of that Portfolio at the NAV determined on the first business day
          following the record date.


          The Portfolios may purchase securities of certain foreign corporations
          considered to be passive foreign investment companies by the IRS. In
          order to avoid taxes and interest that must be paid by the Portfolios
          if these instruments appreciate in value, the Portfolios may make
          various elections permitted by the tax laws. However, these elections
          could require that the Portfolios recognize taxable income, which in
          turn must be distributed.


          Some foreign securities purchased by the Portfolios may be subject to
          foreign taxes which could reduce the yield on such securities. The
          amount of such foreign taxes is expected to be insignificant. The
          Portfolios may from year to year make the election permitted under
          Section 853 of the Code to pass through such taxes to shareholders. If
          such election is not made, any foreign taxes paid or accrued will
          represent an expense to each Portfolio which will reduce its
          investment company taxable income.

          Because Shares of the Portfolios can only be purchased through
          variable insurance contracts or qualified plans, it is anticipated
          that any income dividends or capital gains distributions will be
          exempt from current taxation if left to accumulate within such
          contracts or plans. See the prospectus for the separate account of the
          related insurance company or the plan documents for additional
          information.

                                                                              37

Principal shareholders


          The officers and Trustees of the Portfolios cannot directly own Shares
          of the Portfolios without purchasing an insurance contract through one
          of the participating insurance companies or through a qualified plan.
          As a result, such officers and Trustees as a group own less than 1% of
          the outstanding Shares of each Portfolio. As of April 3, 2000, all of
          the outstanding Shares of the Portfolios were owned by certain
          insurance company separate accounts or qualified plans. The percentage
          ownership of each separate account or plan owning more than 5% of the
          Shares of any Portfolio is as follows:

Miscellaneous information


          Each Portfolio is a series of the Trust, an open-end management
          investment company registered under the 1940 Act and organized as a
          Delaware business trust on May 20, 1993. As of the date of this SAI,
          the Trust is offering fourteen series of shares, known as
          "Portfolios," each of which consists of two or three classes of
          shares. Additional series and/or classes may be created from time to
          time.


SHARES OF THE TRUST

          The Trust is authorized to issue an unlimited number of shares of
          beneficial interest with a par value of $.001 per share for each
          series of the Trust. Shares of each Portfolio are fully paid and
          nonassessable when issued. Shares of a Portfolio participate equally
          in dividends and other distributions by the shares of such Portfolio,
          and in residual assets of that Portfolio in the event of liquidation.
          Shares of each Portfolio have no preemptive, conversion or
          subscription rights.


          The Portfolios each offer two or three classes of shares. The Shares
          discussed in this SAI are offered only in connection with investment
          in and payments under variable insurance contracts and to qualified
          retirement plans. A second class of shares, Retirement Shares, is
          offered only to certain participant directed qualified plans whose
          service providers require a fee from the Trust assets for providing
          certain services to plan participants.


SHAREHOLDER MEETINGS

          The Trust does not intend to hold annual shareholder meetings.
          However, special meetings may be called for a specific Portfolio or
          for the Trust as a whole for purposes such as electing or removing
          Trustees, terminating or reorganizing the Trust, changing fundamental
          policies, or for any other purpose requiring a shareholder vote under
          the 1940 Act. Separate votes are taken by each Portfolio or class only
          if a matter affects or requires the vote of only that Portfolio or
          class or that Portfolio's or class' interest in the matter differs
          from the interest of other Portfolios of the Trust. Shareholder is
          entitled to one vote for each Share owned.

VOTING RIGHTS

          A participating insurance company issuing a variable insurance
          contract will vote shares in the separate account as required by law
          and interpretations thereof, as may be amended or changed from time to
          time. In accordance with current law and interpretations, a
          participating insurance company is required to request voting
          instructions from policy owners and must vote shares in the separate
          account, including shares for which no instructions have been
          received, in proportion to the voting instructions received.
          Additional information may be found in the participating insurance
          company's separate account prospectus.

          The Trustees are responsible for major decisions relating to each
          Portfolio's policies and objectives; the Trustees oversee the
          operation of each Portfolio by its officers and review the investment
          decisions of the officers.

          The present Trustees were elected by the initial trustee of the Trust
          on May 25, 1993, and were approved by the initial shareholder on May
          25, 1993, with the exception of Mr. Craig and Mr. Rothe who were
          appointed by the Trustees as of June 30, 1995 and as of January 1,
          1997, respectively. Under the Trust Instrument, each Trustee will
          continue in office until the termination of the Trust or his earlier
          death, retirement, resignation, bankruptcy, incapacity or removal.
          Vacancies will be filled by a majority of the remaining Trustees,
          subject to the 1940 Act. Therefore, no annual or regular meetings of
          shareholders normally will be held, unless otherwise required by the
          Trust Instrument or the 1940 Act. Subject to the foregoing,
          shareholders have the power to vote to elect or remove Trustees, to
          terminate or reorganize their

                                                                              41

          Portfolio, to amend the Trust Instrument, to bring certain derivative
          actions and on any other matters on which a shareholder vote is
          required by the 1940 Act, the Trust Instrument, the Trust's Bylaws or
          the Trustees.

          As mentioned above in "Shareholder Meetings," each share of each
          portfolio of the Trust has one vote (and fractional votes for
          fractional shares). Shares of all portfolios of the Trust have
          noncumulative voting rights, which means that the holders of more than
          50% of the shares of all series of the Trust voting for the election
          of Trustees can elect 100% of the Trustees if they choose to do so
          and, in such event, the holders of the remaining shares will not be
          able to elect any Trustees.

INDEPENDENT ACCOUNTANTS

          PricewaterhouseCoopers LLP, 950 Seventeenth Street, Suite 2500,
          Denver, Colorado 80202, independent accountants for the Portfolios,
          audit the Portfolios' annual financial statements and prepare their
          tax returns.

REGISTRATION STATEMENT

          The Trust has filed with the SEC, Washington, D.C., a Registration
          Statement under the Securities Act of 1933, as amended, with respect
          to the securities to which this SAI relates. If further information is
          desired with respect to the Portfolios or such securities, reference
          is made to the Registration Statement and the exhibits filed as a part
          thereof.

Performance information


          Quotations of average annual total return for the Shares of a
          Portfolio will be expressed in terms of the average annual compounded
          rate of return of a hypothetical investment in the Shares of such
          Portfolio over periods of 1, 5, and 10 years (up to the life of the
          Portfolio). These are the annual total rates of return that would
          equate the initial amount invested to the ending redeemable value.
          These rates of return are calculated pursuant to the following
          formula: P(1 + T)(n) = ERV (where P = a hypothetical initial payment
          of $1,000, T = the average annual total return, n = the number of
          years and ERV = the ending redeemable value of a hypothetical $1,000
          payment made at the beginning of the period). All total return figures
          reflect the deduction of a proportional share of expenses of the
          Shares of a Portfolio on an annual basis, and assume that all
          dividends and distributions are reinvested when paid. The average
          annual total return of the Shares of each Portfolio, computed as of
          December 31, 1999, is shown in the table below (with the exception of
          Global Life Sciences Portfolio and Global Technology Portfolio, which
          had not commenced operations as of December 31, 1999):

          Yield quotations for a Portfolio's Shares are based on the investment
          income per Share earned during a particular 30-day period (including
          dividends, if any, and interest), less expenses accrued during the
          period ("net investment income"), and are computed by dividing net
          investment income by the net asset value per share on the last day of
          the period, according to the following formula:

                              YIELD = 2[(a - b + 1)(6) - 1]
                                         -----
                                          cd

          where a = dividend and interest income
                b = expenses accrued for the period (net of reimbursements)
                c = average daily number of shares outstanding during the period
                    that were entitled to receive dividends
                d = maximum net asset value per share on the last day of the
                    period

Appendix A

EXPLANATION OF RATING CATEGORIES

          The following is a description of credit ratings issued by two of the
          major credit ratings agencies. Credit ratings evaluate only the safety
          of principal and interest payments, not the market value risk of lower
          quality securities. Credit rating agencies may fail to change credit
          ratings to reflect subsequent events on a timely basis. Although Janus
          Capital considers security ratings when making investment decisions,
          it also performs its own investment analysis and does not rely solely
          on the ratings assigned by credit agencies.

                Investment Grade
                AAA......................... Highest rating; extremely strong capacity to pay principal
                                             and interest.
                AA.......................... High quality; very strong capacity to pay principal and
                                             interest.
                A........................... Strong capacity to pay principal and interest; somewhat more
                                             susceptible to the adverse effects of changing circumstances
                                             and economic conditions.
                BBB......................... Adequate capacity to pay principal and interest; normally
                                             exhibit adequate protection parameters, but adverse economic
                                             conditions or changing circumstances more likely to lead to
                                             a weakened capacity to pay principal and interest than for
                                             higher rated bonds.
                Non-Investment Grade
                BB, B, CCC, CC, C........... Predominantly speculative with respect to the issuer's
                                             capacity to meet required interest and principal payments.
                                             BB -- lowest degree of speculation; C -- the highest degree
                                             of speculation. Quality and protective characteristics
                                             outweighed by large uncertainties or major risk exposure to
                                             adverse conditions.
                D........................... In default.

                Investment Grade
                Aaa......................... Highest quality, smallest degree of investment risk.
                Aa.......................... High quality; together with Aaa bonds, they compose the
                                             high-grade bond group.
                A........................... Upper-medium grade obligations; many favorable investment
                                             attributes.
                Baa......................... Medium-grade obligations; neither highly protected nor
                                             poorly secured. Interest and principal appear adequate for
                                             the present but certain protective elements may be lacking
                                             or may be unreliable over any great length of time.
                Non-Investment Grade
                Ba.......................... More uncertain, with speculative elements. Protection of
                                             interest and principal payments not well safeguarded during
                                             good and bad times.
                B........................... Lack characteristics of desirable investment; potentially
                                             low assurance of timely interest and principal payments or
                                             maintenance of other contract terms over time.
                Caa......................... Poor standing, may be in default; elements of danger with
                                             respect to principal or interest payments.
                Ca.......................... Speculative in a high degree; could be in default or have
                                             other marked shortcomings.
                C........................... Lowest-rated; extremely poor prospects of ever attaining
                                             investment standing.
</TABLE>

          Unrated securities will be treated as noninvestment grade securities
          unless the portfolio manager determines that such securities are the
          equivalent of investment grade securities. Securities that have
          received ratings from more than one agency are considered investment
          grade if at least one agency has rated the security investment grade.

                              May 1, 2000


                 This Statement of Additional Information expands upon and
                 supplements the information contained in the current Prospectus
                 for the Retirement Shares (the "Shares") of the portfolios
                 listed above, each of which is a separate series of Janus Aspen
                 Series, a Delaware business trust. Each of these series of the
                 Trust represents shares of beneficial interest in a separate
                 portfolio of securities and other assets with its own objective
                 and policies. Each Portfolio is managed separately by Janus
                 Capital Corporation.

                 The Shares of the Portfolios may be purchased only by qualified
                 retirement plans. Each Portfolio also offers a second class of
                 shares to the separate account of insurance companies for the
                 purpose of funding variable life insurance policies and
                 variable annuity contracts and certain other qualified
                 retirement plans.


                 This SAI is not a Prospectus and should be read in conjunction
                 with the Portfolios' Prospectus dated May 1, 2000, which is

CLASSIFICATION


          Each Portfolio is a series of the Trust, an open-end, management
          investment company. The Investment Company Act of 1940 ("1940 Act")
          classifies mutual funds as either diversified or nondiversified.
          Aggressive Growth Portfolio and Capital Appreciation Portfolio are
          nondiversified funds. Each of these Portfolios reserves the right to
          become a diversified fund by limiting the investments in which more
          than 5% of its total assets are invested. Growth Portfolio, Balanced
          Portfolio, Equity Income Portfolio, Growth and Income Portfolio,
          International Growth Portfolio, Worldwide Growth Portfolio, Flexible
          Income Portfolio and High-Yield Portfolio are diversified funds.


PORTFOLIO TURNOVER

          The Prospectus includes a discussion of portfolio turnover policies.
          Portfolio turnover is calculated by dividing total purchases or sales,
          whichever is less, by the average monthly value of a Portfolio's
          securities. The following table summarizes the portfolio turnover
          rates for the fiscal periods indicated. The information below is for
          fiscal years ended December 31.

(1) May 1, 1998 (inception) to December 31, 1998, annualized.


INVESTMENT POLICIES AND RESTRICTIONS APPLICABLE TO ALL PORTFOLIOS

          The Portfolios are subject to certain fundamental policies and
          restrictions that may not be changed without shareholder approval.
          Shareholder approval means approval by the lesser of (i) more than 50%
          of the outstanding voting securities of the Trust (or a particular
          Portfolio or particular class of shares if a matter affects just that
          Portfolio or that class of shares), or (ii) 67% or more of the voting
          securities present at a meeting if the holders of more than 50% of the
          outstanding voting securities of the Trust (or a particular Portfolio
          or class of shares) are present or represented by proxy. As
          fundamental policies, each of the Portfolios may not:

          (1) Own more than 10% of the outstanding voting securities of any one
          issuer and, as to fifty percent (50%) of the value of the total assets
          of Aggressive Growth Portfolio and Capital Appreciation Portfolio and
          as to seventy-five percent (75%) of the value of the total assets of
          the other Portfolios, purchase the securities of any one issuer
          (except cash items and "government securities" as defined under the
          Investment Company Act of 1940, as amended, if immediately after and
          as a result of such purchase, the value of the holdings of a Portfolio
          in the securities of such issuer exceeds 5% of the value of such
          Portfolio's total assets. With respect to the other 50% of the value
          of its total assets, Aggressive Growth Portfolio and Capital
          Appreciation Portfolio may invest in the securities of as few as two
          issuers.

          (2) Invest 25% or more of the value of their respective total assets
          in any particular industry (other than U.S. government securities).

<PAGE>

          (3) Invest directly in real estate or interests in real estate;
          however, the Portfolios may own debt or equity securities issued by
          companies engaged in those businesses.

          (4) Purchase or sell physical commodities other than foreign
          currencies unless acquired as a result of ownership of securities (but
          this limitation shall not prevent the Portfolios from purchasing or
          selling options, futures, swaps and forward contracts or from
          investing in securities or other instruments backed by physical
          commodities).

          (5) Lend any security or make any other loan if, as a result, more
          than 25% of a Portfolio's total assets would be lent to other parties
          (but this limitation does not apply to purchases of commercial paper,
          debt securities or repurchase agreements).

          (6) Act as an underwriter of securities issued by others, except to
          the extent that a Portfolio may be deemed an underwriter in connection
          with the disposition of its portfolio securities.

          As a fundamental policy, each Portfolio may, notwithstanding any other
          investment policy or limitation (whether or not fundamental), invest
          all of its assets in the securities of a single open-end management
          investment company with substantially the same fundamental investment
          objective, policies and limitations as such Portfolio.

          The Trustees have adopted additional investment restrictions for the
          Portfolios. These restrictions are operating policies of the
          Portfolios and may be changed by the Trustees without shareholder
          approval. The additional investment restrictions adopted by the
          Trustees to date include the following:

          (a) A Portfolio will not (i) enter into any futures contracts and
          related options for purposes other than bona fide hedging transactions
          within the meaning of Commodity Futures Trading Commission ("CFTC")
          regulations if the aggregate initial margin and premiums required to
          establish positions in futures contracts and related options that do
          not fall within the definition of bona fide hedging transactions will
          exceed 5% of the fair market value of a Portfolio's net assets, after
          taking into account unrealized profits and unrealized losses on any
          such contracts it has entered into; and (ii) enter into any futures
          contracts if the aggregate amount of such Portfolio's commitments
          under outstanding futures contracts positions would exceed the market
          value of its total assets.

          (b) The Portfolios do not currently intend to sell securities short,
          unless they own or have the right to obtain securities equivalent in
          kind and amount to the securities sold short without the payment of
          any additional consideration therefor, and provided that transactions
          in futures, options, swaps and forward contracts are not deemed to
          constitute selling securities short.

          (c) The Portfolios do not currently intend to purchase securities on
          margin, except that the Portfolios may obtain such short-term credits
          as are necessary for the clearance of transactions, and provided that
          margin payments and other deposits in connection with transactions in
          futures, options, swaps and forward contracts shall not be deemed to
          constitute purchasing securities on margin.

          (d) A Portfolio may not mortgage or pledge any securities owned or
          held by such Portfolio in amounts that exceed, in the aggregate, 15%
          of that Portfolio's net asset value, provided that this limitation
          does not apply to reverse repurchase agreements, deposits of assets to
          margin, guarantee positions in futures, options, swaps or forward
          contracts, or the segregation of assets in connection with such
          contracts.

          (e) The Portfolios may borrow money for temporary or emergency
          purposes (not for leveraging or investment) in an amount not exceeding
          25% of the value of their respective total assets (including the
          amount borrowed) less liabilities (other than borrowings). If
          borrowings exceed 25% of the value of a

                                                                               3
<PAGE>

          Portfolio's total assets by reason of a decline in net assets, the
          Portfolio will reduce its borrowings within three business days to the
          extent necessary to comply with the 25% limitation. This policy shall
          not prohibit reverse repurchase agreements, deposits of assets to
          margin or guarantee positions in futures, options, swaps or forward
          contracts, or the segregation of assets in connection with such
          contracts.

          (f) The Portfolios do not currently intend to purchase any security or
          enter into a repurchase agreement, if as a result, more than 15% of
          their respective net assets would be invested in repurchase agreements
          not entitling the holder to payment of principal and interest within
          seven days and in securities that are illiquid by virtue of legal or
          contractual restrictions on resale or the absence of a readily
          available market. The Trustees, or the Portfolios' investment adviser
          acting pursuant to authority delegated by the Trustees, may determine
          that a readily available market exists for securities eligible for
          resale pursuant to Rule 144A under the Securities Act of 1933 ("Rule
          144A Securities"), or any successor to such rule, Section 4(2)
          commercial paper and municipal lease obligations. Accordingly, such
          securities may not be subject to the foregoing limitation.

          (g) The Portfolios may not invest in companies for the purpose of
          exercising control of management.

          Under the terms of an exemptive order received from the Securities and
          Exchange Commission ("SEC"), each of the Portfolios may borrow money
          from or lend money to other funds that permit such transactions and
          for which Janus Capital serves as investment adviser. All such
          borrowing and lending will be subject to the above limits. A Portfolio
          will borrow money through the program only when the costs are equal to
          or lower than the cost of bank loans. Interfund loans and borrowings
          normally extend overnight, but can have a maximum duration of seven
          days. A Portfolio will lend through the program only when the returns
          are higher than those available from other short-term instruments
          (such as repurchase agreements). A Portfolio may have to borrow from a
          bank at a higher interest rate if an interfund loan is called or not
          renewed. Any delay in repayment to a lending Portfolio could result in
          a lost investment opportunity or additional borrowing costs.

          For the purposes of these investment restrictions, the identification
          of the issuer of a municipal obligation depends on the terms and
          conditions of the security. When assets and revenues of a political
          subdivision are separate from those of the government that created the
          subdivision and the security is backed only by the assets and revenues
          of the subdivision, the subdivision is deemed to be the sole issuer.
          Similarly, in the case of an industrial development bond, if the bond
          is backed only by assets and revenues of a nongovernmental user, then
          the nongovernmental user would be deemed to be the sole issuer. If,
          however, in either case, the creating government or some other entity
          guarantees the security, the guarantee would be considered a separate
          security that would be treated as an issue of the guaranteeing entity.

          For purposes of the Portfolios' restriction on investing in a
          particular industry, the Portfolios will rely primarily on industry
          classifications as published by Bloomberg L.P. To the extent that
          Bloomberg L.P. classifications are so broad that the primary economic
          characteristics in a single class are materially different, the
          Portfolios may further classify issuers in accordance with industry
          classifications as published by the SEC.

INVESTMENT POLICIES APPLICABLE TO CERTAIN PORTFOLIOS

          BALANCED PORTFOLIO. As an operational policy, at least 25% of the
          assets of Balanced Portfolio normally will be invested in fixed-income
          securities.

          FLEXIBLE INCOME PORTFOLIO. As a fundamental policy, this Portfolio may
          not purchase a non-income-producing security if, after such purchase,
          less than 80% of the Portfolio's total assets would be invested in
          income-producing securities. Income-producing securities include
          securities that make periodic interest

 4
<PAGE>

          payments as well as those that make interest payments on a deferred
          basis or pay interest only at maturity (e.g., Treasury bills or zero
          coupon bonds).

INVESTMENT STRATEGIES AND RISKS

Cash Position


          As discussed in the Prospectus, when a portfolio manager believes that
          market conditions are unfavorable for profitable investing, or when he
          or she is otherwise unable to locate attractive investment
          opportunities, the Portfolio's investment in cash and similar
          investments may increase. Securities that the Portfolios may invest in
          as a means of receiving a return on idle cash include commercial
          paper, certificates of deposit, repurchase agreements or other
          short-term debt obligations. The Portfolios may also invest in money
          market funds, including funds managed by Janus Capital. (See
          "Investment Company Securities" on page 8).


Illiquid Investments

          Each Portfolio may invest up to 15% of its net assets in illiquid
          investments (i.e., securities that are not readily marketable). The
          Trustees have authorized Janus Capital to make liquidity
          determinations with respect to certain securities, including Rule 144A
          Securities, commercial paper and municipal lease obligations purchased
          by the Portfolios. Under the guidelines established by the Trustees,
          Janus Capital will consider the following factors: (1) the frequency
          of trades and quoted prices for the obligation; (2) the number of
          dealers willing to purchase or sell the security and the number of
          other potential purchasers; (3) the willingness of dealers to
          undertake to make a market in the security; and (4) the nature of the
          security and the nature of the marketplace trades, including the time
          needed to dispose of the security, the method of soliciting offers and
          the mechanics of the transfer. In the case of commercial paper, Janus
          Capital will also consider whether the paper is traded flat or in
          default as to principal and interest and any ratings of the paper by a
          nationally recognized statistical rating organization ("NRSRO"). A
          foreign security that may be freely traded on or through the
          facilities of an offshore exchange or other established offshore
          securities market is not deemed to be a restricted security subject to
          these procedures.

          If illiquid securities exceed 15% of a Portfolio's net assets after
          the time of purchase the Portfolio will take steps to reduce in an
          orderly fashion its holdings of illiquid securities. Because illiquid
          securities may not be readily marketable, a portfolio manager may not
          be able to dispose of them in a timely manner. As a result, a
          Portfolio may be forced to hold illiquid securities while their price
          depreciates. Depreciation in the price of illiquid securities may
          cause the net asset value of a Portfolio to decline.


Securities Lending



          The Portfolios may lend securities to qualified parties (typically
          brokers or other financial institutions) who need to borrow securities
          in order to complete certain transactions such as covering short
          sales, avoiding failures to deliver securities or completing arbitrage
          activities. The Portfolios may seek to earn additional income through
          securities lending. Since there is the risk of delay in recovering a
          loaned security or the risk of loss in collateral rights if the
          borrower fails financially, securities lending will only be made to
          parties that Janus Capital deems creditworthy and in good standing. In
          addition, such loans will only be made if Janus Capital believes the
          benefit from granting such loans justifies the risk. The Portfolios
          will not have the right to vote on securities while they are being
          lent, but it will generally call a loan in anticipation of any
          important vote. All loans will be continuously secured by collateral
          which consists of cash, U.S. government securities, letters of credit
          and such other collateral permitted by the SEC and


                                                                               5
<PAGE>


          policies approved by the Trustees. Cash collateral may be invested in
          money market funds advised by Janus to the extent consistent with
          exemptive relief obtained from the SEC.


Short Sales

          Each Portfolio may engage in "short sales against the box." This
          technique involves selling either a security that a Portfolio owns, or
          a security equivalent in kind and amount to the security sold short
          that the Portfolio has the right to obtain, for delivery at a
          specified date in the future. A Portfolio may enter into a short sale
          against the box to hedge against anticipated declines in the market
          price of portfolio securities. If the value of the securities sold
          short increases prior to the scheduled delivery date, a Portfolio
          loses the opportunity to participate in the gain.

Zero Coupon, Step Coupon and Pay-In-Kind Securities

          Each Portfolio may invest up to 10% (without limit for High-Yield
          Portfolio and Flexible Income Portfolio) of its assets in zero coupon,
          pay-in-kind and step coupon securities. Zero coupon bonds are issued
          and traded at a discount from their face value. They do not entitle
          the holder to any periodic payment of interest prior to maturity. Step
          coupon bonds trade at a discount from their face value and pay coupon
          interest. The coupon rate is low for an initial period and then
          increases to a higher coupon rate thereafter. The discount from the
          face amount or par value depends on the time remaining until cash
          payments begin, prevailing interest rates, liquidity of the security
          and the perceived credit quality of the issuer. Pay-in-kind bonds
          normally give the issuer an option to pay cash at a coupon payment
          date or give the holder of the security a similar bond with the same
          coupon rate and a face value equal to the amount of the coupon payment
          that would have been made. For the purposes of any Portfolio's
          restriction on investing in income-producing securities,
          income-producing securities include securities that make periodic
          interest payments as well as those that make interest payments on a
          deferred basis or pay interest only at maturity (e.g., Treasury bills
          or zero coupon bonds).

          Current federal income tax law requires holders of zero coupon
          securities and step coupon securities to report the portion of the
          original issue discount on such securities that accrues during a given
          year as interest income, even though the holders receive no cash
          payments of interest during the year. In order to qualify as a
          "regulated investment company" under the Internal Revenue Code of 1986
          and the regulations thereunder (the "Code"), a Portfolio must
          distribute its investment company taxable income, including the
          original issue discount accrued on zero coupon or step coupon bonds.
          Because a Portfolio will not receive cash payments on a current basis
          in respect of accrued original-issue discount on zero coupon bonds or
          step coupon bonds during the period before interest payments begin, in
          some years that Portfolio may have to distribute cash obtained from
          other sources in order to satisfy the distribution requirements under
          the Code. A Portfolio might obtain such cash from selling other
          portfolio holdings which might cause that Portfolio to incur capital
          gains or losses on the sale. Additionally, these actions are likely to
          reduce the assets to which Portfolio expenses could be allocated and
          to reduce the rate of return for that Portfolio. In some
          circumstances, such sales might be necessary in order to satisfy cash
          distribution requirements even though investment considerations might
          otherwise make it undesirable for a Portfolio to sell the securities
          at the time.

          Generally, the market prices of zero coupon, step coupon and
          pay-in-kind securities are more volatile than the prices of securities
          that pay interest periodically and in cash and are likely to respond
          to changes in interest rates to a greater degree than other types of
          debt securities having similar maturities and credit quality.

Pass-Through Securities

          The Portfolios may invest in various types of pass-through securities,
          such as mortgage-backed securities, asset-backed securities and
          participation interests. A pass-through security is a share or
          certificate of interest in a pool of debt obligations that have been
          repackaged by an intermediary, such as a bank or broker-dealer. The
          purchaser of a pass-through security receives an undivided interest in
          the underlying pool of securities. The issuers of the underlying
          securities make interest and principal payments to the intermediary
          which are passed through to purchasers, such as the Portfolios. The
          most common type of pass-through securities are mortgage-backed
          securities. Government National Mortgage Association ("GNMA")
          Certificates are mortgage-backed securities that evidence an undivided
          interest in a pool of mortgage loans. GNMA Certificates differ from
          bonds in that principal is paid back monthly by the borrowers over the
          term of the loan rather than returned in a lump sum at maturity. A
          Portfolio will generally purchase "modified pass-through" GNMA
          Certificates, which entitle the holder to receive a share of all
          interest and principal payments paid and owned on the mortgage pool,
          net of fees paid to the "issuer" and GNMA, regardless of whether or
          not the mortgagor actually makes the payment. GNMA Certificates are
          backed as to the timely payment of principal and interest by the full
          faith and credit of the U.S. government.

          The Federal Home Loan Mortgage Corporation ("FHLMC") issues two types
          of mortgage pass-through securities: mortgage participation
          certificates ("PCs") and guaranteed mortgage certificates ("GMCs").
          PCs resemble GNMA Certificates in that each PC represents a pro rata
          share of all interest and principal payments made and owned on the
          underlying pool. FHLMC guarantees timely payments of interest on PCs
          and the full return of principal. GMCs also represent a pro rata
          interest in a pool of mortgages. However, these instruments pay
          interest semiannually and return principal once a year in guaranteed
          minimum payments. This type of security is guaranteed by FHLMC as to
          timely payment of principal and interest but it is not guaranteed by
          the full faith and credit of the U.S. government.

          The Federal National Mortgage Association ("FNMA") issues guaranteed
          mortgage pass-through certificates ("FNMA Certificates"). FNMA
          Certificates resemble GNMA Certificates in that each FNMA Certificate
          represents a pro rata share of all interest and principal payments
          made and owned on the underlying pool. This type of security is
          guaranteed by FNMA as to timely payment of principal and interest but
          it is not guaranteed by the full faith and credit of the U.S.
          government.

          Except for GMCs, each of the mortgage-backed securities described
          above is characterized by monthly payments to the holder, reflecting
          the monthly payments made by the borrowers who received the underlying
          mortgage loans. The payments to the security holders (such as the
          Portfolios), like the payments on the underlying loans, represent both
          principal and interest. Although the underlying mortgage loans are for
          specified periods of time, such as 20 or 30 years, the borrowers can,
          and typically do, pay them off sooner. Thus, the security holders
          frequently receive prepayments of principal in addition to the
          principal that is part of the regular monthly payments. A portfolio
          manager will consider estimated prepayment rates in calculating the
          average-weighted maturity of a Portfolio. A borrower is more likely to
          prepay a mortgage that bears a relatively high rate of interest. This
          means that in times of declining interest rates, higher yielding
          mortgage-backed securities held by a Portfolio might be converted to
          cash and that Portfolio will be forced to accept lower interest rates
          when that cash is used to purchase additional securities in the
          mortgage-backed securities sector or in other investment sectors.
          Additionally, prepayments during such periods will limit a Portfolio's
          ability to participate in as large a market gain as may be experienced
          with a comparable security not subject to prepayment.

                                                                               7
<PAGE>

          Asset-backed securities represent interests in pools of consumer loans
          and are backed by paper or accounts receivables originated by banks,
          credit card companies or other providers of credit. Generally, the
          originating bank or credit provider is neither the obligor nor the
          guarantor of the security, and interest and principal payments
          ultimately depend upon payment of the underlying loans by individuals.
          Tax-exempt asset-backed securities include units of beneficial
          interests in pools of purchase contracts, financing leases, and sales
          agreements that may be created when a municipality enters into an
          installment purchase contract or lease with a vendor. Such securities
          may be secured by the assets purchased or leased by the municipality;
          however, if the municipality stops making payments, there generally
          will be no recourse against the vendor. The market for tax-exempt
          asset-backed securities is still relatively new. These obligations are
          likely to involve unscheduled prepayments of principal.

Investment Company Securities

          From time to time, the Portfolios may invest in securities of other
          investment companies, subject to the provisions of Section 12(d)(1) of
          the 1940 Act. The Portfolios may invest in securities of money market
          funds managed by Janus Capital in excess of the limitations of Section
          12(d)(1) under the terms of an SEC exemptive order obtained by Janus
          Capital and the Janus funds.

Depositary Receipts


          The Portfolios may invest in sponsored and unsponsored American
          Depositary Receipts ("ADRs"), which are receipts issued by an American
          bank or trust company evidencing ownership of underlying securities
          issued by a foreign issuer. ADRs, in registered form, are designed for
          use in U.S. securities markets. Unsponsored ADRs may be created
          without the participation of the foreign issuer. Holders of these ADRs
          generally bear all the costs of the ADR facility, whereas foreign
          issuers typically bear certain costs in a sponsored ADR. The bank or
          trust company depositary of an unsponsored ADR may be under no
          obligation to distribute shareholder communications received from the
          foreign issuer or to pass through voting rights. The Portfolios may
          also invest in European Depositary Receipts ("EDRs"), Global
          Depositary Receipts ("GDRs") and in other similar instruments
          representing securities of foreign companies. EDRs and GDRs are
          securities that are typically issued by foreign banks or foreign trust
          companies, although U.S. banks or U.S. trust companies may issue them.
          EDRs and GDRs are structured similarly to the arrangements of ADRs.
          EDRs, in bearer form, are designed for use in European securities
          markets.


          Depositary Receipts are generally subject to the same sort of risks as
          direct investments in a foreign country, such as, currency risk,
          political and economic risk, and market risk, because their values
          depend on the performance of a foreign security denominated in its
          home currency. The risks of foreign investing are addressed in some
          detail in the Portfolios' prospectus.

Municipal Obligations

          The Portfolios may invest in municipal obligations issued by states,
          territories and possessions of the United States and the District of
          Columbia. The value of municipal obligations can be affected by
          changes in their actual or perceived credit quality. The credit
          quality of municipal obligations can be affected by, among other
          things, the financial condition of the issuer or guarantor, the
          issuer's future borrowing plans and sources of revenue, the economic
          feasibility of the revenue bond project or general borrowing purpose,
          political or economic developments in the region where the security is
          issued, and the liquidity of the security. Because municipal
          securities are generally traded over-the-counter, the liquidity of a
          particular issue often depends on the willingness of dealers to make a
          market in the security. The liquidity of some municipal obligations
          may be enhanced by demand features, which would enable a Portfolio to
          demand payment on short notice from the issuer or a financial
          intermediary.

Other Income-Producing Securities

          Other types of income producing securities that the Portfolios may
          purchase include, but are not limited to, the following types of
          securities:

          VARIABLE AND FLOATING RATE OBLIGATIONS. These types of securities have
          variable or floating rates of interest and, under certain limited
          circumstances, may have varying principal amounts. These securities
          pay interest at rates that are adjusted periodically according to a
          specified formula, usually with reference to some interest rate index
          or market interest rate. The floating rate tends to decrease the
          security's price sensitivity to changes in interest rates. These types
          of securities are relatively long-term instruments that often carry
          demand features permitting the holder to demand payment of principal
          at any time or at specified intervals prior to maturity.

          In order to most effectively use these investments, a portfolio
          manager must correctly assess probable movements in interest rates.
          This involves different skills than those used to select most
          portfolio securities. If the portfolio manager incorrectly forecasts
          such movements, a Portfolio could be adversely affected by the use of
          variable or floating rate obligations.

          STANDBY COMMITMENTS. These instruments, which are similar to a put,
          give a Portfolio the option to obligate a broker, dealer or bank to
          repurchase a security held by that Portfolio at a specified price.

          TENDER OPTION BONDS. Tender option bonds are relatively long-term
          bonds that are coupled with the agreement of a third party (such as a
          broker, dealer or bank) to grant the holders of such securities the
          option to tender the securities to the institution at periodic
          intervals.

          INVERSE FLOATERS. Inverse floaters are debt instruments whose interest
          bears an inverse relationship to the interest rate on another
          security. No Portfolio will invest more than 5% of its assets in
          inverse floaters. Similar to variable and floating rate obligations,
          effective use of inverse floaters requires skills different from those
          needed to select most portfolio securities. If movements in interest
          rates are incorrectly anticipated, a fund could lose money or its NAV
          could decline by the use of inverse floaters.

          STRIP BONDS. Strip bonds are debt securities that are stripped of
          their interest (usually by a financial intermediary) after the
          securities are issued. The market value of these securities generally
          fluctuates more in response to changes in interest rates than
          interest-paying securities of comparable maturity.

          The Portfolios will purchase standby commitments, tender option bonds
          and instruments with demand features primarily for the purpose of
          increasing the liquidity of their holdings.

Repurchase and Reverse Repurchase Agreements

          In a repurchase agreement, a Portfolio purchases a security and
          simultaneously commits to resell that security to the seller at an
          agreed upon price on an agreed upon date within a number of days
          (usually not more than seven) from the date of purchase. The resale
          price consists of the purchase price plus an agreed upon incremental
          amount that is unrelated to the coupon rate or maturity of the
          purchased security. A repurchase agreement involves the obligation of
          the seller to pay the agreed upon price, which obligation is in effect
          secured by the value (at least equal to the amount of the agreed upon
          resale price and marked-to-market daily) of the underlying security or
          "collateral." A risk associated with repurchase agreements is the
          failure of the seller to repurchase the securities as agreed, which
          may cause a Portfolio to suffer a loss if the market value of such
          securities declines before they can be liquidated on the open market.
          In the event of bankruptcy or insolvency of the seller, a Portfolio
          may encounter delays and incur costs in liquidating the underlying
          security. Repurchase agreements that mature in more than seven days
          are subject to the

                                                                               9

          15% limit on illiquid investments. While it is not possible to
          eliminate all risks from these transactions, it is the policy of the
          Portfolios to limit repurchase agreements to those parties whose
          creditworthiness has been reviewed and found satisfactory by Janus
          Capital.

          A Portfolio may use reverse repurchase agreements to obtain cash to
          satisfy unusually heavy redemption requests or for other temporary or
          emergency purposes without the necessity of selling portfolio
          securities, or to earn additional income on portfolio securities, such
          as Treasury bills or notes. In a reverse repurchase agreement, a
          Portfolio sells a portfolio security to another party, such as a bank
          or broker-dealer, in return for cash and agrees to repurchase the
          instrument at a particular price and time. While a reverse repurchase
          agreement is outstanding, a Portfolio will maintain cash and
          appropriate liquid assets in a segregated custodial account to cover
          its obligation under the agreement. The Portfolios will enter into
          reverse repurchase agreements only with parties that Janus Capital
          deems creditworthy. Using reverse repurchase agreements to earn
          additional income involves the risk that the interest earned on the
          invested proceeds is less than the expense of the reverse repurchase
          agreement transaction. This technique may also have a leveraging
          effect on the Portfolio, although the Portfolio's intent to segregate
          assets in the amount of the reverse repurchase agreement minimizes
          this effect.


High-Yield/High-Risk Bonds



          Flexible Income Portfolio and High-Yield Portfolio may invest without
          limit in bonds that are rated below investment grade (e.g., bonds
          rated BB or lower by Standard & Poor's Ratings Services or Ba or lower
          by Moody's Investors Service, Inc.). No other Portfolio intends to
          invest 35% or more of its net assets in such bonds. Lower rated bonds
          involve a higher degree of credit risk, which is the risk that the
          issuer will not make interest or principal payments when due. In the
          event of an unanticipated default, a Portfolio would experience a
          reduction in its income, and could expect a decline in the market
          value of the bonds so affected.



          Any Portfolio may also invest in unrated bonds of foreign and domestic
          issuers. Unrated bonds, while not necessarily of lower quality than
          rated bonds, may not have as broad a market. Because of the size and
          perceived demand of the issue, among other factors, certain
          municipalities may not incur the costs of obtaining a rating. A
          Portfolio's manager will analyze the creditworthiness of the issuer,
          as well as any financial institution or other party responsible for
          payments on the bond, in determining whether to purchase unrated
          municipal bonds. Unrated bonds will be included in the 35% limit of
          each Portfolio unless its manager deems such securities to be the
          equivalent of investment grade bonds.


          Subject to the above limits, each Portfolio may purchase defaulted
          securities only when its portfolio manager believes, based upon
          analysis of the financial condition, results of operations and
          economic outlook of an issuer, that there is potential for resumption
          of income payments and that the securities offer an unusual
          opportunity for capital appreciation. Notwithstanding the portfolio
          manager's belief about the resumption of income, however, the purchase
          of any security on which payment of interest or dividends is suspended
          involves a high degree of risk. Such risk includes, among other
          things, the following:

          FINANCIAL AND MARKET RISKS. Investments in securities that are in
          default involve a high degree of financial and market risks that can
          result in substantial or, at times, even total losses. Issuers of
          defaulted securities may have substantial capital needs and may become
          involved in bankruptcy or reorganization proceedings. Among the
          problems involved in investments in such issuers is the fact that it
          may be difficult to obtain information about the condition of such
          issuers. The market prices of such securities also are subject to
          abrupt and erratic movements and above average price volatility, and
          the spread between the bid and asked prices of such securities may be
          greater than normally expected.

          DISPOSITION OF PORTFOLIO SECURITIES. Although these Portfolios
          generally will purchase securities for which their portfolio managers
          expect an active market to be maintained, defaulted securities may be
          less actively traded than other securities and it may be difficult to
          dispose of substantial holdings of such securities at prevailing
          market prices. The Portfolios will limit holdings of any such
          securities to amounts that the portfolio managers believe could be
          readily sold, and holdings of such securities would, in any event, be
          limited so as not to limit the Portfolios' ability to readily dispose
          of securities to meet redemptions.

          OTHER. Defaulted securities require active monitoring and may, at
          times, require participation in bankruptcy or receivership proceedings
          on behalf of the Portfolios.

Futures, Options and Other Derivative Instruments

          FUTURES CONTRACTS. The Portfolios may enter into contracts for the
          purchase or sale for future delivery of fixed-income securities,
          foreign currencies or contracts based on financial indices, including
          indices of U.S. government securities, foreign government securities,
          equity or fixed-income securities. U.S. futures contracts are traded
          on exchanges which have been designated "contract markets" by the CFTC
          and must be executed through a futures commission merchant ("FCM"), or
          brokerage firm, which is a member of the relevant contract market.
          Through their clearing corporations, the exchanges guarantee
          performance of the contracts as between the clearing members of the
          exchange.

          The buyer or seller of a futures contract is not required to deliver
          or pay for the underlying instrument unless the contract is held until
          the delivery date. However, both the buyer and seller are required to
          deposit "initial margin" for the benefit of the FCM when the contract
          is entered into. Initial margin deposits are equal to a percentage of
          the contract's value, as set by the exchange on which the contract is
          traded, and may be maintained in cash or certain other liquid assets
          by the Portfolios' custodian or subcustodian for the benefit of the
          FCM. Initial margin payments are similar to good faith deposits or
          performance bonds. Unlike margin extended by a securities broker,
          initial margin payments do not constitute purchasing securities on
          margin for purposes of the Portfolio's investment limitations. If the
          value of either party's position declines, that party will be required
          to make additional "variation margin" payments for the benefit of the
          FCM to settle the change in value on a daily basis. The party that has
          a gain may be entitled to receive all or a portion of this amount. In
          the event of the bankruptcy of the FCM that holds margin on behalf of
          a Portfolio, that Portfolio may be entitled to return of margin owed
          to such Portfolio only in proportion to the amount received by the
          FCM's other customers. Janus Capital will attempt to minimize the risk
          by careful monitoring of the creditworthiness of the FCMs with which
          the Portfolios do business and by depositing margin payments in a
          segregated account with the Portfolios' custodian.

          The Portfolios intend to comply with guidelines of eligibility for
          exclusion from the definition of the term "commodity pool operator"
          adopted by the CFTC and the National Futures Association, which
          regulate trading in the futures markets. The Portfolios will use
          futures contracts and related options primarily for bona fide hedging
          purposes within the meaning of CFTC regulations. To the extent that
          the Portfolios hold positions in futures contracts and related options
          that do not fall within the definition of bona fide hedging
          transactions, the aggregate initial margin and premiums required to
          establish such positions will not exceed 5% of the fair market value
          of a Portfolio's net assets, after taking into account unrealized
          profits and unrealized losses on any such contracts it has entered
          into.

          Although a Portfolio will segregate cash and liquid assets in an
          amount sufficient to cover its open futures obligations, the
          segregated assets would be available to that Portfolio immediately
          upon closing out the futures position, while settlement of securities
          transactions could take several days. However, because a

                                                                              11
<PAGE>

          Portfolio's cash that may otherwise be invested would be held
          uninvested or invested in other liquid assets so long as the futures
          position remains open, such Portfolio's return could be diminished due
          to the opportunity losses of foregoing other potential investments.

          A Portfolio's primary purpose in entering into futures contracts is to
          protect that Portfolio from fluctuations in the value of securities or
          interest rates without actually buying or selling the underlying debt
          or equity security. For example, if the Portfolio anticipates an
          increase in the price of stocks, and it intends to purchase stocks at
          a later time, that Portfolio could enter into a futures contract to
          purchase a stock index as a temporary substitute for stock purchases.
          If an increase in the market occurs that influences the stock index as
          anticipated, the value of the futures contracts will increase, thereby
          serving as a hedge against that Portfolio not participating in a
          market advance. This technique is sometimes known as an anticipatory
          hedge. To the extent a Portfolio enters into futures contracts for
          this purpose, the segregated assets maintained to cover such
          Portfolio's obligations with respect to the futures contracts will
          consist of liquid assets from its portfolio in an amount equal to the
          difference between the contract price and the aggregate value of the
          initial and variation margin payments made by that Portfolio with
          respect to the futures contracts. Conversely, if a Portfolio holds
          stocks and seeks to protect itself from a decrease in stock prices,
          the Portfolio might sell stock index futures contracts, thereby hoping
          to offset the potential decline in the value of its portfolio
          securities by a corresponding increase in the value of the futures
          contract position. A Portfolio could protect against a decline in
          stock prices by selling portfolio securities and investing in money
          market instruments, but the use of futures contracts enables it to
          maintain a defensive position without having to sell portfolio
          securities.


          If a Portfolio owns bonds and the portfolio manager expects interest
          rates to increase, that Portfolio may take a short position in
          interest rate futures contracts. Taking such a position would have
          much the same effect as that Portfolio selling bonds in its portfolio.
          If interest rates increase as anticipated, the value of the bonds
          would decline, but the value of that Portfolio's interest rate futures
          contract will increase thereby keeping the net asset value of that
          Portfolio from declining as much as it may have otherwise. If, on the
          other hand, a portfolio manager expects interest rates to decline,
          that Portfolio may take a long position in interest rate futures
          contracts in anticipation of later closing out the futures position
          and purchasing the bonds. Although a Portfolio can accomplish similar
          results by buying securities with long maturities and selling
          securities with short maturities, given the greater liquidity of the
          futures market than the cash market, it may be possible to accomplish
          the same result more easily and more quickly by using futures
          contracts as an investment tool to reduce risk.


          The ordinary spreads between prices in the cash and futures markets,
          due to differences in the nature of those markets, are subject to
          distortions. First, all participants in the futures market are subject
          to initial margin and variation margin requirements. Rather than
          meeting additional variation margin requirements, investors may close
          out futures contracts through offsetting transactions which could
          distort the normal price relationship between the cash and futures
          markets. Second, the liquidity of the futures market depends on
          participants entering into offsetting transactions rather than making
          or taking delivery of the instrument underlying a futures contract. To
          the extent participants decide to make or take delivery, liquidity in
          the futures market could be reduced and prices in the futures market
          distorted. Third, from the point of view of speculators, the margin
          deposit requirements in the futures market are less onerous than
          margin requirements in the securities market. Therefore, increased
          participation by speculators in the futures market may cause temporary
          price distortions. Due to the possibility of the foregoing
          distortions, a correct forecast of general price trends by a portfolio
          manager still may not result in a successful use of futures.

          Futures contracts entail risks. Although the Portfolios believe that
          use of such contracts will benefit the Portfolios, a Portfolio's
          overall performance could be worse than if such Portfolio had not
          entered into futures contracts if the portfolio manager's investment
          judgement proves incorrect. For example, if a Portfolio has hedged
          against the effects of a possible decrease in prices of securities
          held in its portfolio and prices increase instead, that Portfolio will
          lose part or all of the benefit of the increased value of these
          securities because of offsetting losses in its futures positions. In
          addition, if a Portfolio has insufficient cash, it may have to sell
          securities from its portfolio to meet daily variation margin
          requirements. Those sales may be, but will not necessarily be, at
          increased prices which reflect the rising market and may occur at a
          time when the sales are disadvantageous to such Portfolio.

          The prices of futures contracts depend primarily on the value of their
          underlying instruments. Because there are a limited number of types of
          futures contracts, it is possible that the standardized futures
          contracts available to a Portfolio will not match exactly such
          Portfolio's current or potential investments. A Portfolio may buy and
          sell futures contracts based on underlying instruments with different
          characteristics from the securities in which it typically
          invests - for example, by hedging investments in portfolio securities
          with a futures contract based on a broad index of securities - which
          involves a risk that the futures position will not correlate precisely
          with the performance of such Portfolio's investments.

          Futures prices can also diverge from the prices of their underlying
          instruments, even if the underlying instruments closely correlate with
          a Portfolio's investments. Futures prices are affected by factors such
          as current and anticipated short-term interest rates, changes in
          volatility of the underlying instruments and the time remaining until
          expiration of the contract. Those factors may affect securities prices
          differently from futures prices. Imperfect correlations between a
          Portfolio's investments and its futures positions also may result from
          differing levels of demand in the futures markets and the securities
          markets, from structural differences in how futures and securities are
          traded, and from imposition of daily price fluctuation limits for
          futures contracts. A Portfolio may buy or sell futures contracts with
          a greater or lesser value than the securities it wishes to hedge or is
          considering purchasing in order to attempt to compensate for
          differences in historical volatility between the futures contract and
          the securities, although this may not be successful in all cases. If
          price changes in a Portfolio's futures positions are poorly correlated
          with its other investments, its futures positions may fail to produce
          desired gains or result in losses that are not offset by the gains in
          that Portfolio's other investments.

          Because futures contracts are generally settled within a day from the
          date they are closed out, compared with a settlement period of three
          days for some types of securities, the futures markets can provide
          superior liquidity to the securities markets. Nevertheless, there is
          no assurance that a liquid secondary market will exist for any
          particular futures contract at any particular time. In addition,
          futures exchanges may establish daily price fluctuation limits for
          futures contracts and may halt trading if a contract's price moves
          upward or downward more than the limit in a given day. On volatile
          trading days when the price fluctuation limit is reached, it may be
          impossible for a Portfolio to enter into new positions or close out
          existing positions. If the secondary market for a futures contract is
          not liquid because of price fluctuation limits or otherwise, a
          Portfolio may not be able to promptly liquidate unfavorable futures
          positions and potentially could be required to continue to hold a
          futures position until the delivery date, regardless of changes in its
          value. As a result, such Portfolio's access to other assets held to
          cover its futures positions also could be impaired.

          OPTIONS ON FUTURES CONTRACTS. The Portfolios may buy and write put and
          call options on futures contracts. An option on a future gives a
          Portfolio the right (but not the obligation) to buy or sell a futures
          contract at a specified price on or before a specified date. The
          purchase of a call option on a futures

                                                                              13
<PAGE>

          contract is similar in some respects to the purchase of a call option
          on an individual security. Depending on the pricing of the option
          compared to either the price of the futures contract upon which it is
          based or the price of the underlying instrument, ownership of the
          option may or may not be less risky than ownership of the futures
          contract or the underlying instrument. As with the purchase of futures
          contracts, when a Portfolio is not fully invested it may buy a call
          option on a futures contract to hedge against a market advance.

          The writing of a call option on a futures contract constitutes a
          partial hedge against declining prices of the security or foreign
          currency which is deliverable under, or of the index comprising, the
          futures contract. If the futures price at the expiration of the option
          is below the exercise price, a Portfolio will retain the full amount
          of the option premium which provides a partial hedge against any
          decline that may have occurred in that Portfolio's holdings. The
          writing of a put option on a futures contract constitutes a partial
          hedge against increasing prices of the security or foreign currency
          which is deliverable under, or of the index comprising, the futures
          contract. If the futures price at expiration of the option is higher
          than the exercise price, a Portfolio will retain the full amount of
          the option premium which provides a partial hedge against any increase
          in the price of securities which that Portfolio is considering buying.
          If a call or put option a Portfolio has written is exercised, such
          Portfolio will incur a loss which will be reduced by the amount of the
          premium it received. Depending on the degree of correlation between
          the change in the value of its portfolio securities and changes in the
          value of the futures positions, a Portfolio's losses from existing
          options on futures may to some extent be reduced or increased by
          changes in the value of portfolio securities.

          The purchase of a put option on a futures contract is similar in some
          respects to the purchase of protective put options on portfolio
          securities. For example, a Portfolio may buy a put option on a futures
          contract to hedge its portfolio against the risk of falling prices or
          rising interest rates.

          The amount of risk a Portfolio assumes when it buys an option on a
          futures contract is the premium paid for the option plus related
          transaction costs. In addition to the correlation risks discussed
          above, the purchase of an option also entails the risk that changes in
          the value of the underlying futures contract will not be fully
          reflected in the value of the options bought.

          FORWARD CONTRACTS. A forward contract is an agreement between two
          parties in which one party is obligated to deliver a stated amount of
          a stated asset at a specified time in the future and the other party
          is obligated to pay a specified amount for the assets at the time of
          delivery. The Portfolios may enter into forward contracts to purchase
          and sell government securities, equity or income securities, foreign
          currencies or other financial instruments. Forward contracts generally
          are traded in an interbank market conducted directly between traders
          (usually large commercial banks) and their customers. Unlike futures
          contracts, which are standardized contracts, forward contracts can be
          specifically drawn to meet the needs of the parties that enter into
          them. The parties to a forward contract may agree to offset or
          terminate the contract before its maturity, or may hold the contract
          to maturity and complete the contemplated exchange.

          The following discussion summarizes the Portfolios' principal uses of
          forward foreign currency exchange contracts ("forward currency
          contracts"). A Portfolio may enter into forward currency contracts
          with stated contract values of up to the value of that Portfolio's
          assets. A forward currency contract is an obligation to buy or sell an
          amount of a specified currency for an agreed price (which may be in
          U.S. dollars or a foreign currency). A Portfolio will exchange foreign
          currencies for U.S. dollars and for other foreign currencies in the
          normal course of business and may buy and sell currencies through
          forward currency contracts in order to fix a price for securities it
          has agreed to buy or sell ("transaction hedge"). A Portfolio

 14
<PAGE>

          also may hedge some or all of its investments denominated in a foreign
          currency or exposed to foreign currency fluctuations against a decline
          in the value of that currency relative to the U.S. dollar by entering
          into forward currency contracts to sell an amount of that currency (or
          a proxy currency whose performance is expected to replicate or exceed
          the performance of that currency relative to the U.S. dollar)
          approximating the value of some or all of its portfolio securities
          denominated in that currency ("position hedge") or by participating in
          options or futures contracts with respect to the currency. A Portfolio
          also may enter into a forward currency contract with respect to a
          currency where the Portfolio is considering the purchase or sale of
          investments denominated in that currency but has not yet selected the
          specific investments ("anticipatory hedge"). In any of these
          circumstances a Portfolio may, alternatively, enter into a forward
          currency contract to purchase or sell one foreign currency for a
          second currency that is expected to perform more favorably relative to
          the U.S. dollar if the portfolio manager believes there is a
          reasonable degree of correlation between movements in the two
          currencies ("cross-hedge").

          These types of hedging minimize the effect of currency appreciation as
          well as depreciation, but do not eliminate fluctuations in the
          underlying U.S. dollar equivalent value of the proceeds of or rates of
          return on a Portfolio's foreign currency denominated portfolio
          securities. The matching of the increase in value of a forward
          contract and the decline in the U.S. dollar equivalent value of the
          foreign currency denominated asset that is the subject of the hedge
          generally will not be precise. Shifting a Portfolio's currency
          exposure from one foreign currency to another removes that Portfolio's
          opportunity to profit from increases in the value of the original
          currency and involves a risk of increased losses to such Portfolio if
          its portfolio manager's projection of future exchange rates is
          inaccurate. Proxy hedges and cross-hedges may result in losses if the
          currency used to hedge does not perform similarly to the currency in
          which hedged securities are denominated. Unforeseen changes in
          currency prices may result in poorer overall performance for a
          Portfolio than if it had not entered into such contracts.

          The Portfolios will cover outstanding forward currency contracts by
          maintaining liquid portfolio securities denominated in or whose value
          is tied to the currency underlying the forward contract or the
          currency being hedged. To the extent that a Portfolio is not able to
          cover its forward currency positions with underlying portfolio
          securities, the Portfolios' custodian will segregate cash or other
          liquid assets having a value equal to the aggregate amount of such
          Portfolio's commitments under forward contracts entered into with
          respect to position hedges, cross-hedges and anticipatory hedges. If
          the value of the securities used to cover a position or the value of
          segregated assets declines, a Portfolio will find alternative cover or
          segregate additional cash or other liquid assets on a daily basis so
          that the value of the covered and segregated assets will be equal to
          the amount of such Portfolio's commitments with respect to such
          contracts. As an alternative to segregating assets, a Portfolio may
          buy call options permitting such Portfolio to buy the amount of
          foreign currency being hedged by a forward sale contract or a
          Portfolio may buy put options permitting it to sell the amount of
          foreign currency subject to a forward buy contract.

          While forward contracts are not currently regulated by the CFTC, the
          CFTC may in the future assert authority to regulate forward contracts.
          In such event, the Portfolios' ability to utilize forward contracts
          may be restricted. In addition, a Portfolio may not always be able to
          enter into forward contracts at attractive prices and may be limited
          in its ability to use these contracts to hedge Portfolio assets.

          OPTIONS ON FOREIGN CURRENCIES. The Portfolios may buy and write
          options on foreign currencies in a manner similar to that in which
          futures or forward contracts on foreign currencies will be utilized.
          For example, a decline in the U.S. dollar value of a foreign currency
          in which portfolio securities are denominated will reduce the U.S.
          dollar value of such securities, even if their value in the foreign
          currency remains constant. In order to protect against such
          diminutions in the value of portfolio securities, a

                                                                              15
<PAGE>

          Portfolio may buy put options on the foreign currency. If the value of
          the currency declines, such Portfolio will have the right to sell such
          currency for a fixed amount in U.S. dollars, thereby offsetting, in
          whole or in part, the adverse effect on its portfolio.

          Conversely, when a rise in the U.S. dollar value of a currency in
          which securities to be acquired are denominated is projected, thereby
          increasing the cost of such securities, a Portfolio may buy call
          options on the foreign currency. The purchase of such options could
          offset, at least partially, the effects of the adverse movements in
          exchange rates. As in the case of other types of options, however, the
          benefit to a Portfolio from purchases of foreign currency options will
          be reduced by the amount of the premium and related transaction costs.
          In addition, if currency exchange rates do not move in the direction
          or to the extent projected, a Portfolio could sustain losses on
          transactions in foreign currency options that would require such
          Portfolio to forego a portion or all of the benefits of advantageous
          changes in those rates.

          The Portfolios may also write options on foreign currencies. For
          example, to hedge against a potential decline in the U.S. dollar value
          of foreign currency denominated securities due to adverse fluctuations
          in exchange rates, a Portfolio could, instead of purchasing a put
          option, write a call option on the relevant currency. If the expected
          decline occurs, the option will most likely not be exercised and the
          decline in value of portfolio securities will be offset by the amount
          of the premium received.

          Similarly, instead of purchasing a call option to hedge against a
          potential increase in the U.S. dollar cost of securities to be
          acquired, a Portfolio could write a put option on the relevant
          currency which, if rates move in the manner projected, should expire
          unexercised and allow that Portfolio to hedge the increased cost up to
          the amount of the premium. As in the case of other types of options,
          however, the writing of a foreign currency option will constitute only
          a partial hedge up to the amount of the premium. If exchange rates do
          not move in the expected direction, the option may be exercised and a
          Portfolio would be required to buy or sell the underlying currency at
          a loss which may not be offset by the amount of the premium. Through
          the writing of options on foreign currencies, a Portfolio also may
          lose all or a portion of the benefits which might otherwise have been
          obtained from favorable movements in exchange rates.

          The Portfolios may write covered call options on foreign currencies. A
          call option written on a foreign currency by a Portfolio is "covered"
          if that Portfolio owns the foreign currency underlying the call or has
          an absolute and immediate right to acquire that foreign currency
          without additional cash consideration (or for additional cash
          consideration held in a segregated account by its custodian) upon
          conversion or exchange of other foreign currencies held in its
          portfolio. A call option is also covered if a Portfolio has a call on
          the same foreign currency in the same principal amount as the call
          written if the exercise price of the call held (i) is equal to or less
          than the exercise price of the call written or (ii) is greater than
          the exercise price of the call written, if the difference is
          maintained by such Portfolio in cash or other liquid assets in a
          segregated account with the Portfolios' custodian.

          The Portfolios also may write call options on foreign currencies for
          cross-hedging purposes. A call option on a foreign currency is for
          cross-hedging purposes if it is designed to provide a hedge against a
          decline due to an adverse change in the exchange rate in the U.S.
          dollar value of a security which a Portfolio owns or has the right to
          acquire and which is denominated in the currency underlying the
          option. Call options on foreign currencies which are entered into for
          cross-hedging purposes are not covered. However, in such
          circumstances, a Portfolio will collateralize the option by
          segregating cash or other liquid assets in an amount not less than the
          value of the underlying foreign currency in U.S. dollars
          marked-to-market daily.

          OPTIONS ON SECURITIES. In an effort to increase current income and to
          reduce fluctuations in net asset value, the Portfolios may write
          covered put and call options and buy put and call options on
          securities

 16
<PAGE>

          that are traded on United States and foreign securities exchanges and
          over-the-counter. The Portfolios may write and buy options on the same
          types of securities that the Portfolios may purchase directly.

          A put option written by a Portfolio is "covered" if that Portfolio (i)
          segregates cash not available for investment or other liquid assets
          with a value equal to the exercise price of the put with the
          Portfolios' custodian or (ii) holds a put on the same security and in
          the same principal amount as the put written and the exercise price of
          the put held is equal to or greater than the exercise price of the put
          written. The premium paid by the buyer of an option will reflect,
          among other things, the relationship of the exercise price to the
          market price and the volatility of the underlying security, the
          remaining term of the option, supply and demand and interest rates.

          A call option written by a Portfolio is "covered" if that Portfolio
          owns the underlying security covered by the call or has an absolute
          and immediate right to acquire that security without additional cash
          consideration (or for additional cash consideration held in a
          segregated account by the Portfolios' custodian) upon conversion or
          exchange of other securities held in its portfolio. A call option is
          also deemed to be covered if a Portfolio holds a call on the same
          security and in the same principal amount as the call written and the
          exercise price of the call held (i) is equal to or less than the
          exercise price of the call written or (ii) is greater than the
          exercise price of the call written if the difference is maintained by
          that Portfolio in cash and other liquid assets in a segregated account
          with its custodian.

          The Portfolios also may write call options that are not covered for
          cross-hedging purposes. A Portfolio collateralizes its obligation
          under a written call option for cross-hedging purposes by segregating
          cash or other liquid assets in an amount not less than the market
          value of the underlying security, marked-to-market daily. A Portfolio
          would write a call option for cross-hedging purposes, instead of
          writing a covered call option, when the premium to be received from
          the cross-hedge transaction would exceed that which would be received
          from writing a covered call option and its portfolio manager believes
          that writing the option would achieve the desired hedge.

          The writer of an option may have no control over when the underlying
          securities must be sold, in the case of a call option, or bought, in
          the case of a put option, since with regard to certain options, the
          writer may be assigned an exercise notice at any time prior to the
          termination of the obligation. Whether or not an option expires
          unexercised, the writer retains the amount of the premium. This
          amount, of course, may, in the case of a covered call option, be
          offset by a decline in the market value of the underlying security
          during the option period. If a call option is exercised, the writer
          experiences a profit or loss from the sale of the underlying security.
          If a put option is exercised, the writer must fulfill the obligation
          to buy the underlying security at the exercise price, which will
          usually exceed the then market value of the underlying security.

          The writer of an option that wishes to terminate its obligation may
          effect a "closing purchase transaction." This is accomplished by
          buying an option of the same series as the option previously written.
          The effect of the purchase is that the writer's position will be
          canceled by the clearing corporation. However, a writer may not effect
          a closing purchase transaction after being notified of the exercise of
          an option. Likewise, an investor who is the holder of an option may
          liquidate its position by effecting a "closing sale transaction." This
          is accomplished by selling an option of the same series as the option
          previously bought. There is no guarantee that either a closing
          purchase or a closing sale transaction can be effected.

          In the case of a written call option, effecting a closing transaction
          will permit a Portfolio to write another call option on the underlying
          security with either a different exercise price or expiration date or
          both. In the case of a written put option, such transaction will
          permit a Portfolio to write another put option to the

                                                                              17
<PAGE>

          extent that the exercise price is secured by deposited liquid assets.
          Effecting a closing transaction also will permit a Portfolio to use
          the cash or proceeds from the concurrent sale of any securities
          subject to the option for other investments. If a Portfolio desires to
          sell a particular security from its portfolio on which it has written
          a call option, such Portfolio will effect a closing transaction prior
          to or concurrent with the sale of the security.

          A Portfolio will realize a profit from a closing transaction if the
          price of the purchase transaction is less than the premium received
          from writing the option or the price received from a sale transaction
          is more than the premium paid to buy the option. A Portfolio will
          realize a loss from a closing transaction if the price of the purchase
          transaction is more than the premium received from writing the option
          or the price received from a sale transaction is less than the premium
          paid to buy the option. Because increases in the market of a call
          option generally will reflect increases in the market price of the
          underlying security, any loss resulting from the repurchase of a call
          option is likely to be offset in whole or in part by appreciation of
          the underlying security owned by a Portfolio.

          An option position may be closed out only where a secondary market for
          an option of the same series exists. If a secondary market does not
          exist, the Portfolio may not be able to effect closing transactions in
          particular options and the Portfolio would have to exercise the
          options in order to realize any profit. If a Portfolio is unable to
          effect a closing purchase transaction in a secondary market, it will
          not be able to sell the underlying security until the option expires
          or it delivers the underlying security upon exercise. The absence of a
          liquid secondary market may be due to the following: (i) insufficient
          trading interest in certain options, (ii) restrictions imposed by a
          national securities exchange ("Exchange") on which the option is
          traded on opening or closing transactions or both, (iii) trading
          halts, suspensions or other restrictions imposed with respect to
          particular classes or series of options or underlying securities, (iv)
          unusual or unforeseen circumstances that interrupt normal operations
          on an Exchange, (v) the facilities of an Exchange or of the Options
          Clearing Corporation ("OCC") may not at all times be adequate to
          handle current trading volume, or (vi) one or more Exchanges could,
          for economic or other reasons, decide or be compelled at some future
          date to discontinue the trading of options (or a particular class or
          series of options), in which event the secondary market on that
          Exchange (or in that class or series of options) would cease to exist,
          although outstanding options on that Exchange that had been issued by
          the OCC as a result of trades on that Exchange would continue to be
          exercisable in accordance with their terms.

          A Portfolio may write options in connection with buy-and-write
          transactions. In other words, a Portfolio may buy a security and then
          write a call option against that security. The exercise price of such
          call will depend upon the expected price movement of the underlying
          security. The exercise price of a call option may be below
          ("in-the-money"), equal to ("at-the-money") or above
          ("out-of-the-money") the current value of the underlying security at
          the time the option is written. Buy-and-write transactions using
          in-the-money call options may be used when it is expected that the
          price of the underlying security will remain flat or decline
          moderately during the option period. Buy-and-write transactions using
          at-the-money call options may be used when it is expected that the
          price of the underlying security will remain fixed or advance
          moderately during the option period. Buy-and-write transactions using
          out-of-the-money call options may be used when it is expected that the
          premiums received from writing the call option plus the appreciation
          in the market price of the underlying security up to the exercise
          price will be greater than the appreciation in the price of the
          underlying security alone. If the call options are exercised in such
          transactions, a Portfolio's maximum gain will be the premium received
          by it for writing the option, adjusted upwards or downwards by the
          difference between that Portfolio's purchase price of the security and
          the exercise price.

 18
<PAGE>

          If the options are not exercised and the price of the underlying
          security declines, the amount of such decline will be offset by the
          amount of premium received.

          The writing of covered put options is similar in terms of risk and
          return characteristics to buy-and-write transactions. If the market
          price of the underlying security rises or otherwise is above the
          exercise price, the put option will expire worthless and a Portfolio's
          gain will be limited to the premium received. If the market price of
          the underlying security declines or otherwise is below the exercise
          price, a Portfolio may elect to close the position or take delivery of
          the security at the exercise price and that Portfolio's return will be
          the premium received from the put options minus the amount by which
          the market price of the security is below the exercise price.

          A Portfolio may buy put options to hedge against a decline in the
          value of its portfolio. By using put options in this way, a Portfolio
          will reduce any profit it might otherwise have realized in the
          underlying security by the amount of the premium paid for the put
          option and by transaction costs.

          A Portfolio may buy call options to hedge against an increase in the
          price of securities that it may buy in the future. The premium paid
          for the call option plus any transaction costs will reduce the
          benefit, if any, realized by such Portfolio upon exercise of the
          option, and, unless the price of the underlying security rises
          sufficiently, the option may expire worthless to that Portfolio.

          EURODOLLAR INSTRUMENTS. A Portfolio may make investments in Eurodollar
          instruments. Eurodollar instruments are U.S. dollar-denominated
          futures contracts or options thereon which are linked to the London
          Interbank Offered Rate ("LIBOR"), although foreign
          currency-denominated instruments are available from time to time.
          Eurodollar futures contracts enable purchasers to obtain a fixed rate
          for the lending of funds and sellers to obtain a fixed rate for
          borrowings. A Portfolio might use Eurodollar futures contracts and
          options thereon to hedge against changes in LIBOR, to which many
          interest rate swaps and fixed-income instruments are linked.

          SWAPS AND SWAP-RELATED PRODUCTS. A Portfolio may enter into interest
          rate swaps, caps and floors on either an asset-based or
          liability-based basis, depending upon whether it is hedging its assets
          or its liabilities, and will usually enter into interest rate swaps on
          a net basis (i.e., the two payment streams are netted out, with a
          Portfolio receiving or paying, as the case may be, only the net amount
          of the two payments). The net amount of the excess, if any, of a
          Portfolio's obligations over its entitlement with respect to each
          interest rate swap will be calculated on a daily basis and an amount
          of cash or other liquid assets having an aggregate net asset value at
          least equal to the accrued excess will be maintained in a segregated
          account by the Portfolios' custodian. If a Portfolio enters into an
          interest rate swap on other than a net basis, it would maintain a
          segregated account in the full amount accrued on a daily basis of its
          obligations with respect to the swap. A Portfolio will not enter into
          any interest rate swap, cap or floor transaction unless the unsecured
          senior debt or the claims-paying ability of the other party thereto is
          rated in one of the three highest rating categories of at least one
          NRSRO at the time of entering into such transaction. Janus Capital
          will monitor the creditworthiness of all counterparties on an ongoing
          basis. If there is a default by the other party to such a transaction,
          a Portfolio will have contractual remedies pursuant to the agreements
          related to the transaction.

          The swap market has grown substantially in recent years with a large
          number of banks and investment banking firms acting both as principals
          and as agents utilizing standardized swap documentation. Janus Capital
          has determined that, as a result, the swap market has become
          relatively liquid. Caps and floors are more recent innovations for
          which standardized documentation has not yet been developed and,
          accordingly, they are less liquid than swaps. To the extent a
          Portfolio sells (i.e., writes) caps and floors, it

                                                                              19
<PAGE>

          will segregate cash or other liquid assets having an aggregate net
          asset value at least equal to the full amount, accrued on a daily
          basis, of its obligations with respect to any caps or floors.

          There is no limit on the amount of interest rate swap transactions
          that may be entered into by a Portfolio. These transactions may in
          some instances involve the delivery of securities or other underlying
          assets by a Portfolio or its counterparty to collateralize obligations
          under the swap. Under the documentation currently used in those
          markets, the risk of loss with respect to interest rate swaps is
          limited to the net amount of the payments that a Portfolio is
          contractually obligated to make. If the other party to an interest
          rate swap that is not collateralized defaults, a Portfolio would risk
          the loss of the net amount of the payments that it contractually is
          entitled to receive. A Portfolio may buy and sell (i.e., write) caps
          and floors without limitation, subject to the segregation requirement
          described above.

          ADDITIONAL RISKS OF OPTIONS ON FOREIGN CURRENCIES, FORWARD CONTRACTS
          AND FOREIGN INSTRUMENTS. Unlike transactions entered into by the
          Portfolios in futures contracts, options on foreign currencies and
          forward contracts are not traded on contract markets regulated by the
          CFTC or (with the exception of certain foreign currency options) by
          the SEC. To the contrary, such instruments are traded through
          financial institutions acting as market-makers, although foreign
          currency options are also traded on certain Exchanges, such as the
          Philadelphia Stock Exchange and the Chicago Board Options Exchange,
          subject to SEC regulation. Similarly, options on currencies may be
          traded over-the-counter. In an over-the-counter trading environment,
          many of the protections afforded to Exchange participants will not be
          available. For example, there are no daily price fluctuation limits,
          and adverse market movements could therefore continue to an unlimited
          extent over a period of time. Although the buyer of an option cannot
          lose more than the amount of the premium plus related transaction
          costs, this entire amount could be lost. Moreover, an option writer
          and a buyer or seller of futures or forward contracts could lose
          amounts substantially in excess of any premium received or initial
          margin or collateral posted due to the potential additional margin and
          collateral requirements associated with such positions.

          Options on foreign currencies traded on Exchanges are within the
          jurisdiction of the SEC, as are other securities traded on Exchanges.
          As a result, many of the protections provided to traders on organized
          Exchanges will be available with respect to such transactions. In
          particular, all foreign currency option positions entered into on an
          Exchange are cleared and guaranteed by the OCC, thereby reducing the
          risk of counterparty default. Further, a liquid secondary market in
          options traded on an Exchange may be more readily available than in
          the over-the-counter market, potentially permitting a Portfolio to
          liquidate open positions at a profit prior to exercise or expiration,
          or to limit losses in the event of adverse market movements.

          The purchase and sale of exchange-traded foreign currency options,
          however, is subject to the risks of the availability of a liquid
          secondary market described above, as well as the risks regarding
          adverse market movements, margining of options written, the nature of
          the foreign currency market, possible intervention by governmental
          authorities and the effects of other political and economic events. In
          addition, exchange-traded options on foreign currencies involve
          certain risks not presented by the over-the-counter market. For
          example, exercise and settlement of such options must be made
          exclusively through the OCC, which has established banking
          relationships in applicable foreign countries for this purpose. As a
          result, the OCC may, if it determines that foreign governmental
          restrictions or taxes would prevent the orderly settlement of foreign
          currency option exercises, or would result in undue burdens on the OCC
          or its clearing member, impose special procedures on exercise and
          settlement, such as technical changes in the mechanics of delivery of
          currency, the fixing of dollar settlement prices or prohibitions on
          exercise.

          In addition, options on U.S. government securities, futures contracts,
          options on futures contracts, forward contracts and options on foreign
          currencies may be traded on foreign exchanges and over-the-counter in
          foreign countries. Such transactions are subject to the risk of
          governmental actions affecting trading in or the prices of foreign
          currencies or securities. The value of such positions also could be
          adversely affected by (i) other complex foreign political and economic
          factors, (ii) lesser availability than in the United States of data on
          which to make trading decisions, (iii) delays in a Portfolio's ability
          to act upon economic events occurring in foreign markets during
          non-business hours in the United States, (iv) the imposition of
          different exercise and settlement terms and procedures and margin
          requirements than in the United States, and (v) low trading volume.

                                                                              21

Investment adviser

          As stated in the Prospectus, each Portfolio has an Investment Advisory
          Agreement with Janus Capital, 100 Fillmore Street, Denver, Colorado
          80206-4928. Each Advisory Agreement provides that Janus Capital will
          furnish continuous advice and recommendations concerning the
          Portfolios' investments, provide office space for the Portfolios, and
          pay the salaries, fees and expenses of all Portfolio officers and of
          those Trustees who are affiliated with Janus Capital. Janus Capital
          also may make payments to selected broker-dealer firms or institutions
          which were instrumental in the acquisition of shareholders for the
          Portfolios or other Janus Funds or which perform recordkeeping or
          other services with respect to shareholder accounts. The minimum
          aggregate size required for eligibility for such payments, and the
          factors in selecting the broker-dealer firms and institutions to which
          they will be made, are determined from time to time by Janus Capital.
          Janus Capital is also authorized to perform the management and
          administrative services necessary for the operation of the Portfolios.

          The Portfolios pay custodian and transfer agent fees and expenses,
          brokerage commissions and dealer spreads and other expenses in
          connection with the execution of portfolio transactions, legal and
          accounting expenses, interest and taxes, registration fees, expenses
          of shareholders' meetings and reports to shareholders, fees and
          expenses of Portfolio Trustees who are not affiliated with Janus
          Capital and other costs of complying with applicable laws regulating
          the sale of Portfolio shares. Pursuant to the Advisory Agreements,
          Janus Capital furnishes certain other services, including net asset
          value determination, portfolio accounting and recordkeeping, for which
          the Portfolios may reimburse Janus Capital for its costs.


          Growth Portfolio, Aggressive Growth Portfolio, Capital Appreciation
          Portfolio, Balanced Portfolio, Equity Income Portfolio and Growth and
          Income Portfolio, International Growth Portfolio and Worldwide Growth
          Portfolio have each agreed to compensate Janus Capital for its
          services by the monthly payment of a fee at the annual rate of 0.65%
          of the average daily net assets of each Portfolio. This fee is the
          same or lower than the fee that each of the Equity Portfolios paid
          under its old agreement during its most recent fiscal year.



          Janus Capital has agreed to reimburse Equity Income Portfolio by the
          amount, if any, that such Portfolio's normal operating expenses in any
          fiscal year, including the investment advisory fee but excluding the
          distribution fee and participant administration fee described below,
          brokerage commissions, interest, taxes and extraordinary expenses,
          exceed an annual rate of 1.25% of the average daily net assets of the
          Portfolio until at least the next annual renewal of the advisory
          agreements.



          High-Yield Portfolio has agreed to compensate Janus Capital for its
          services by the monthly payment of a fee at the annual rate of .75% of
          the first $300 million of average daily net assets of the Portfolio
          and .65% of the average daily net assets in excess of $300 million.
          Flexible Income Portfolio has agreed to compensate Janus Capital for
          its services by the monthly payment of a fee at the annual rate of
          .65% of the first $300 million of the average daily net assets of the
          Portfolio, plus .55% of the average daily net assets of the Portfolio
          in excess of $300 million. Janus Capital has agreed to waive the
          advisory fee payable of High Yield Portfolio and Flexible Income
          Portfolio in an amount equal to the amount, if any, that the
          Portfolio's normal operating expenses in any fiscal year, including
          the investment advisory fee but excluding the distribution fee and
          participant administration fee described below, brokerage commissions,
          interest, taxes and extraordinary expenses, exceed 1% of the average
          daily net assets for a fiscal year. Janus Capital has agreed to
          continue such waivers until at least the next annual renewal of the
          advisory agreements.

(1) In addition to these fee waivers, Janus Capital has agreed to reduce the
    advisory fee of the Growth, Aggressive Growth, Capital Appreciation,
    Balanced, Equity Income, Growth and Income, International Growth and
    Worldwide Growth Portfolios to the extent that such fee exceeds the
    effective rate of the Janus retail fund corresponding to such Portfolio.

(2) May 1, 1997 (inception) to December 31, 1997.
(3) Fee waiver by Janus Capital exceeded the advisory fee.

(4) May 1, 1998 (inception) to December 31, 1998.



          The Advisory Agreement for each of the Portfolios is dated July 1,
          1997. The Equity Portfolios' Advisory Agreements were each amended
          effective May 1, 2000 to decrease the management fees. Each Advisory
          Agreement will continue in effect from July 1, 2001, and thereafter
          from year to year so long as such continuance is approved annually by
          a majority of the Portfolios' Trustees who are not parties to the
          Advisory Agreements or interested persons of any such party, and by
          either a majority of the outstanding voting shares or the Trustees of
          the Portfolios. Each Advisory Agreement (i) may be terminated without
          the payment of any penalty by any Portfolio or Janus Capital on 60
          days' written notice; (ii) terminates automatically in the event of
          its assignment; and (iii) generally, may not be amended without the
          approval by vote of a majority of the Trustees of the affected
          Portfolio, including the Trustees who are not interested persons of
          that Portfolio or Janus Capital and, to the extent required by the
          1940 Act, the vote of a majority of the outstanding voting securities
          of that Portfolio.


          Janus Capital acts as sub-adviser for a number of private-label mutual
          funds and provides separate account advisor services for institutional
          accounts. Investment decisions for each account managed by Janus
          Capital, including the Portfolios, are made independently from those
          for any other account that is or may in the future become managed by
          Janus Capital or its affiliates. If, however, a number of accounts
          managed by Janus Capital are contemporaneously engaged in the purchase
          or sale of the same security, the orders may be aggregated and/or the
          transactions may be averaged as to price and allocated equitably to
          each account. In some cases, this policy might adversely affect the
          price paid or received by an account or the size of the position
          obtained or liquidated for an account. Pursuant to an exemptive order
          granted by the SEC, the Portfolios and other portfolios advised by
          Janus Capital may also transfer daily uninvested cash balances into
          one or more joint trading accounts. Assets in the joint trading
          accounts are invested in money market instruments and the proceeds are
          allocated to the participating portfolios on a pro rata basis.


          Kansas City Southern Industries, Inc. ("KCSI"), indirectly through its
          wholly owned subsidiary, Stilwell Financial Inc., owns approximately
          81% of the outstanding voting stock of Janus Capital. KCSI is a


                                                                              23

          publicly traded holding company whose primary subsidiaries are engaged
          in transportation, information processing and financial services.
          Thomas H. Bailey, President and Chairman of the Board of Janus
          Capital, owns approximately 12% of Janus Capital's voting stock and,
          by agreement with KCSI, selects at least a majority of Janus Capital's
          Board, subject to the approval of Stilwell Financial, which cannot be
          unreasonably withheld.



          KCSI has announced its intention to separate its transportation and
          financial services businesses. KCSI anticipates the separation to be
          completed in the first half of 2000.


          Each account managed by Janus Capital has its own investment objective
          and policies and is managed accordingly by a particular portfolio
          manager or team of portfolio managers. As a result, from time to time
          two or more different managed accounts may pursue divergent investment
          strategies with respect to investments or categories of investments.


          Janus Capital does not permit the Portfolios' portfolio managers to
          purchase and sell securities for their own accounts except under the
          limited exceptions contained in the Portfolios' Code of Ethics
          ("Code"). The Portfolios' Code of Ethics is on file with and available
          through the SEC Web site at www.sec.gov. The Code applies to
          Directors/Trustees of Janus Capital and the Portfolios, and employees
          of Janus Capital and the Trust, and requires investment personnel,
          inside Directors/Trustees of Janus Capital and the Portfolios and
          certain other designated employees deemed to have access to current
          trading information to pre-clear all transactions in securities not
          otherwise exempt under the Code. Requests for trading authorization
          will be denied when, among other reasons, the proposed personal
          transaction would be contrary to the provisions of the policy or would
          be deemed to adversely affect any transaction then known to be under
          consideration for or to have been effected on behalf of any client
          account, including the Portfolios.



          In addition to the pre-clearance requirement described above, the Code
          subjects such personnel to various trading restrictions and reporting
          obligations. All reportable transactions are required to be reviewed
          for compliance with the Code. Those persons also may be required under
          certain circumstances to forfeit their profits made from personal
          trading.



          The provisions of the Code are administered by and subject to
          exceptions authorized by Janus Capital.

          80217-3375, a wholly-owned subsidiary of Janus Capital, is the
          Portfolios' transfer agent. In addition, Janus Service provides
          certain other administrative, recordkeeping and shareholder relations
          services to the Portfolios. Janus Service Corporation receives a
          participant administration fee at an annual rate of up to 0.25% of the
          average daily net assets of each Portfolio for providing or procuring
          recordkeeping, subaccounting and other administrative services to
          plans and plan participants who invest in the shares of the
          Portfolios. Janus Service expects to use this fee to compensate
          qualified plan service providers for providing these services (at an
          annual rate of up to 0.25% of the average daily net assets of the
          Shares attributable to plan participants receiving services from each
          service provider). Services provided by qualified plan service
          providers may include but are not limited to participant
          recordkeeping, processing and aggregating purchase and redemption
          transactions, providing periodic statements, forwarding prospectuses,
          shareholder reports and other materials to existing plan participants,
          and other participant administrative services.



          For the year ended December 31, 1998, the total amounts paid by the
          Shares to Janus Service (substantially all of which Janus Service paid
          out as to qualified plan service providers) are summarized below:

Note: These Portfolios and the other Portfolios that are not included in the
      tables above paid a de minimis amount of participant administration fees
      in connection with seed capital invested by Janus Capital in the Shares of
      such Portfolios. This amount was rebated back to Janus Capital.



          The Portfolios pay DST Systems, Inc., a subsidiary of KCSI, license
          fees at the annual rate of $3.06 per shareholder account for the
          equity portfolios and $3.98 per shareholder account for the
          fixed-income portfolios for the use of DST's shareholder accounting
          system. The Portfolios also pay DST $1.10 per


                                                                              25

          closed shareholder account. The Portfolios pay DST for the use of its
          portfolio and fund accounting system a monthly base fee of $250 to
          $1,250 per month based on the number of Janus funds using the system
          and an asset charge of $1 per million dollars of net assets (not to
          exceed $500 per month).

          The Trustees have authorized the Portfolios to use another affiliate
          of DST as introducing broker for certain Portfolio transactions as a
          means to reduce Portfolio expenses through credits against the charges
          of DST and its affiliates with regard to commissions earned by such
          affiliate. DST charges shown above are net of such credits. See
          "Portfolio Transactions and Brokerage."

          Janus Distributors, Inc., 100 Fillmore Street, Denver, Colorado
          80206-4928, a wholly-owned subsidiary of Janus Capital, is the Trust's
          distributor. Janus Distributors is registered as a broker-dealer under
          the Securities Exchange Act of 1934 and is a member of the National
          Association of Securities Dealers, Inc.

Portfolio transactions and brokerage

          Decisions as to the assignment of portfolio business for the
          Portfolios and negotiation of its commission rates are made by Janus
          Capital whose policy is to obtain the "best execution" (prompt and
          reliable execution at the most favorable security price) of all
          portfolio transactions. The Portfolios may trade foreign securities in
          foreign countries because the best available market for these
          securities is often on foreign exchanges. In transactions on foreign
          stock exchanges, brokers' commissions are frequently fixed and are
          often higher than in the United States, where commissions are
          negotiated.

          In selecting brokers and dealers and in negotiating commissions, Janus
          Capital considers a number of factors, including but not limited to:
          Janus Capital's knowledge of currently available negotiated commission
          rates or prices of securities currently available and other current
          transaction costs; the nature of the security being traded; the size
          and type of the transaction; the nature and character of the markets
          for the security to be purchased or sold; the desired timing of the
          trade; the activity existing and expected in the market for the
          particular security; confidentiality; the quality of the execution,
          clearance and settlement services; financial stability of the broker
          or dealer; the existence of actual or apparent operational problems of
          any broker or dealer; rebates of commissions by a broker to a
          Portfolio or to a third party service provider to the Portfolio to pay
          Portfolio expenses; and research products or services provided. In
          recognition of the value of the foregoing factors, Janus Capital may
          place portfolio transactions with a broker or dealer with whom it has
          negotiated a commission that is in excess of the commission another
          broker or dealer would have charged for effecting that transaction if
          Janus Capital determines in good faith that such amount of commission
          was reasonable in relation to the value of the brokerage and research
          provided by such broker or dealer viewed in terms of either that
          particular transaction or of the overall responsibilities of Janus
          Capital. Research may include furnishing advice, either directly or
          through publications or writings, as to the value of securities, the
          advisability of purchasing or selling specific securities and the
          availability of securities or purchasers or sellers of securities;
          furnishing seminars, information, analyses and reports concerning
          issuers, industries, securities, trading markets and methods,
          legislative developments, changes in accounting practices, economic
          factors and trends and portfolio strategy; access to research
          analysts, corporate management personnel, industry experts, economists
          and government officials; comparative performance evaluation and
          technical measurement services and quotation services, and products
          and other services (such as third party publications, reports and
          analyses, and computer and electronic access, equipment, software,
          information and accessories that deliver, process or otherwise utilize
          information, including the research described above) that assist Janus
          Capital in carrying out its responsibilities. Research received from
          brokers or dealers is supplemental to Janus Capital's own research
          efforts. Most brokers and dealers used by Janus Capital provide
          research and other services described above.

                                                                              27

          For the year ended December 31, 1999, the total brokerage commissions

          services provided to the Portfolios are summarized below:

</TABLE>


Note: Portfolios that are not included in the table did not pay any commissions
      related to research for the stated period.

          Janus Capital may use research products and services in servicing
          other accounts in addition to the Portfolios. If Janus Capital
          determines that any research product or service has a mixed use, such
          that it also serves functions that do not assist in the investment
          decision-making process, Janus Capital may allocate the costs of such
          service or product accordingly. Only that portion of the product or
          service that Janus Capital determines will assist it in the investment
          decision-making process may be paid for in brokerage commission
          dollars. Such allocation may create a conflict of interest for Janus
          Capital.

          Janus Capital does not enter into agreements with any brokers
          regarding the placement of securities transactions because of the
          research services they provide. It does, however, have an internal
          procedure for allocating transactions in a manner consistent with its
          execution policy to brokers that it has identified as providing
          superior executions and research, research-related products or
          services which benefit its advisory clients, including the Portfolios.
          Research products and services incidental to effecting securities
          transactions furnished by brokers or dealers may be used in servicing
          any or all of Janus Capital's clients and such research may not
          necessarily be used by Janus Capital in connection with the accounts
          which paid commissions to the broker-dealer providing such research
          products and services.

          Janus Capital may consider sales of Portfolio Shares or shares of
          other Janus funds by a broker-dealer or the recommendation of a
          broker-dealer to its customers that they purchase Portfolio Shares as
          a factor in the selection of broker-dealers to execute Portfolio
          transactions. Janus Capital may also consider payments made by brokers
          effecting transactions for a Portfolio (i) to the Portfolio or (ii) to
          other persons on behalf of the Portfolio for services provided to the
          Portfolio for which it would be obligated to pay. In placing Portfolio
          business with such broker-dealers, Janus Capital will seek the best
          execution of each transaction.

          When the Portfolios purchase or sell a security in the
          over-the-counter market, the transaction takes place directly with a
          principal market-maker, without the use of a broker, except in those
          circumstances where in the opinion of Janus Capital better prices and
          executions will be achieved through the use of a broker.

          The Portfolios' Trustees have authorized Janus Capital to place
          transactions with DST Securities, Inc. ("DSTS"), a wholly-owned
          broker-dealer subsidiary of DST. Janus Capital may do so if it
          reasonably believes that the quality of the transaction and the
          associated commission are fair and reasonable and if, overall, the
          associated transaction costs, net of any credits described above under
          "Custodian, Transfer Agent and Certain Affiliations," are lower than
          those that would otherwise be incurred.

Note: Portfolios that are not included in the table did not pay brokerage
      commissions because securities transactions for such Portfolios involved
      dealers acting as principals.


          Included in such brokerage commissions are the following amounts paid

* The difference between commissions paid to DSTS and expenses reduced
  constitute commissions paid to an unaffiliated clearing broker.
+ Differences in the percentage of total commissions versus the percentage of
  total transactions are due, in part, to variations among share prices and
  number of shares traded, while average price per share commission rates were
  substantially the same.

Shares of the trust

NET ASSET VALUE DETERMINATION

          As stated in the Prospectus, the net asset value ("NAV") of the Shares
          of each Portfolio is determined once each day on which the NYSE is
          open, at the close of its regular trading session (normally 4:00 p.m.,
          New York time, Monday through Friday). The NAV of the Shares of each
          Portfolio is not determined on days the NYSE is closed (generally, New
          Year's Day, Martin Luther King Day, Presidents' Day, Good Friday,
          Memorial Day, Independence Day, Labor Day, Thanksgiving and
          Christmas). The per Share NAV of the Shares of each Portfolio is
          determined by dividing the total value of a Portfolio's securities and
          other assets, less liabilities, attributable to the Shares of a
          Portfolio, by the total number of Shares outstanding. In determining
          NAV, securities listed on an Exchange, the NASDAQ National Market and
          foreign markets are valued at the closing prices on such markets, or
          if such price is lacking for the trading period immediately preceding
          the time of determination, such securities are valued at their current
          bid price. Municipal securities held by the Portfolios are traded
          primarily in the over-the-counter market. Valuations of such
          securities are furnished by one or more pricing services employed by
          the Portfolios and are based upon last trade or closing sales prices
          or a computerized matrix system or appraisals obtained by a pricing
          service, in each case in reliance upon information concerning market
          transactions and quotations from recognized municipal securities
          dealers. Other securities that are traded on the over-the-counter
          market are valued at their closing bid prices. Foreign securities and
          currencies are converted to U.S. dollars using the exchange rate in
          effect at the close of the NYSE. Each Portfolio will determine the
          market value of individual securities held by it, by using prices
          provided by one or more professional pricing services which may
          provide market prices to other funds, or, as needed, by obtaining
          market quotations from independent broker-dealers. Short-term
          securities maturing within 60 days are valued on an amortized cost
          basis. Securities for which quotations are not readily available, and
          other assets, are valued at fair values determined in good faith under
          procedures established by and under the supervision of the Trustees.

          Trading in securities on European and Far Eastern securities exchanges
          and over-the-counter markets is normally completed well before the
          close of business on each business day in New York (i.e., a day on
          which the NYSE is open). In addition, European or Far Eastern
          securities trading generally or in a particular country or countries
          may not take place on all business days in New York. Furthermore,
          trading takes place in Japanese markets on certain Saturdays and in
          various foreign markets on days which are not business days in New
          York and on which a Portfolio's NAV is not calculated. A Portfolio
          calculates its NAV per Share, and therefore effects sales, redemptions
          and repurchases of its Shares, as of the close of the NYSE once on
          each day on which the NYSE is open. Such calculation may not take
          place contemporaneously with the determination of the prices of the
          foreign portfolio securities used in such calculation.

PURCHASES

          Shares of the Portfolios can be purchased only by qualified retirement
          plans. Certain designated organizations are authorized to receive
          purchase orders on the Portfolios' behalf and those organizations are
          authorized to designate their agents and affiliates as intermediaries
          to receive purchase orders. Purchase orders are deemed received by a
          Portfolio when authorized organizations, their agents or affiliates
          receive the order. The Portfolios are not responsible for the failure
          of any designated organization or its agents or affiliates to carry
          out its obligations to its customers. Shares of the Portfolios are
          purchased at the NAV per Share as determined at the close of the
          regular trading session of the NYSE next occurring after a purchase
          order is received and accepted by a Portfolio or its authorized agent.
          In order to receive a day's price, your order must be received by the
          close of the regular trading session of the NYSE as described above in
          "Net Asset Value Determination." Your plan documents contain detailed
          information about investing in the different Portfolios.

DISTRIBUTION PLAN

          Under a distribution plan ("Plan") adopted in accordance with Rule
          12b-1 under the 1940 Act, the Shares may pay Janus Distributors, the
          Trust's distributor, a fee at an annual rate of up to 0.25% of the
          average daily net assets of the Shares of a Portfolio. Under the terms
          of the Plan, the Trust is authorized to make payments to Janus
          Distributors for remittance to qualified plan service providers as
          compensation for distribution and shareholder servicing performed by
          such service providers. The Plan is a compensation type plan and
          permits the payment at an annual rate of up to 0.25% of the average
          daily net assets of the Shares of a Portfolio for activities which are
          primarily intended to result in sales of the Shares, including but not
          limited to preparing, printing and distributing prospectuses,
          Statements of Additional Information, shareholder reports, and
          educational materials to prospective and existing plan participants;
          responding to inquiries by qualified plan participants; receiving and
          answering correspondence and similar activities. On December 10, 1996,
          Trustees unanimously approved the Plan which became effective May 1,
          1997. The Plan and any Rule 12b-1 related agreement that is entered
          into by the Portfolios or Janus Distributors in connection with the
          Plan will continue in effect for a period of more than one year only
          so long as continuance is specifically approved at least annually by a
          vote of a majority of the Trustees, and of a majority of the Trustees
          who are not interested persons (as defined in the 1940 Act) of the
          Trust and who have no direct or indirect financial interest in the
          operation of the Plan or any related agreements ("12b-1 Trustees").
          All material amendments to the Plan must be approved by a majority
          vote of the Trustees, including a majority of the 12b-1 Trustees, at a
          meeting called for that purpose. In addition, the Plan may be
          terminated at any time, without penalty, by vote of a majority of the
          outstanding Shares of a Portfolio or by vote of a majority of 12b-1
          Trustees.


          For the year ended December 31, 1999, the total amounts paid by the
          Shares to Janus Distributors (substantially all of which Janus
          Distributors paid out as compensation to broker-dealers and other
          service providers) under the 12b-1 plan are summarized below:

Note: These Portfolios and the other Portfolios that are not included in the
      table paid a de minimis amount of 12b-1 fees in connection with seed
      capital invested by Janus Capital in the Shares of such Portfolios. This
      amount was rebated back to Janus Capital.

REDEMPTIONS


          Redemptions, like purchases, may only be effected through qualified
          retirement plans. Certain designated organizations are authorized to
          receive redemption orders on the Portfolios' behalf and those
          organizations are authorized to designate their agents and affiliates
          as intermediaries to receive redemption orders. Redemption orders are
          deemed received by a Portfolio when authorized organizations, their
          agents or affiliates receive the order. The Portfolios are not
          responsible for the failure of any designated organization or its
          agents or affiliates to carry out its obligations to its customers.
          Shares normally will be redeemed for cash, although each Portfolio
          retains the right to redeem some or all of its Shares in kind under
          unusual


                                                                              37

          circumstances, in order to protect the interests of remaining
          shareholders, or to accommodate a request by a particular shareholder
          that does not adversely affect the interest of the remaining
          shareholders, by delivery of securities selected from its assets at
          its discretion. However, the Portfolios are governed by Rule 18f-1
          under the 1940 Act, which requires each Portfolio to redeem shares
          solely in cash up to the lesser of $250,000 or 1% of the NAV of that
          Portfolio during any 90-day period for any one shareholder. Should
          redemptions by any shareholder exceed such limitation, a Portfolio
          will have the option of redeeming the excess in cash or in kind. If
          shares are redeemed in kind, the redeeming shareholder might incur
          brokerage costs in converting the assets to cash. The method of
          valuing securities used to make redemptions in kind will be the same
          as the method of valuing portfolio securities described under "Shares
          of the Trust - Net Asset Value Determination" and such valuation will
          be made as of the same time the redemption price is determined.


          The right to require the Portfolios to redeem their shares may be
          suspended, or the date of payment may be postponed, whenever (1)
          trading on the NYSE is restricted, as determined by the SEC, or the
          NYSE is closed except for holidays and weekends, (2) the SEC permits
          such suspension and so orders, or (3) an emergency exists as
          determined by the SEC so that disposal of securities or determination
          of NAV is not reasonably practicable.

Income dividends, capital gains distributions and tax status


          It is a policy of the Shares of the Portfolios to make distributions
          of substantially all of their respective investment income and any net
          realized capital gains. The Portfolios intend to qualify as regulated
          investment companies by satisfying certain requirements prescribed by
          Subchapter M of the Internal Revenue Code ("Code"). In addition, each
          Portfolio intends to comply with the diversification requirements of
          Code Section 817(h) related to the tax-deferred status of insurance
          company separate accounts.


          All income dividends and capital gains distributions, if any, on a
          Portfolio's Shares are reinvested automatically in additional Shares
          of that Portfolio at the NAV determined on the first business day
          following the record date.


          The Portfolios may purchase securities of certain foreign corporations
          considered to be passive foreign investment companies by the IRS. In
          order to avoid taxes and interest that must be paid by the Portfolios
          if these instruments appreciate in value, the Portfolios may make
          various elections permitted by the tax laws. However, these elections
          could require that the Portfolios recognize taxable income, which in
          turn must be distributed.


          Some foreign securities purchased by the Portfolios may be subject to
          foreign taxes which could reduce the yield on such securities. The
          amount of such foreign taxes is expected to be insignificant. The
          Portfolios may from year to year make the election permitted under
          Section 853 of the Code to pass through such taxes to shareholders. If
          such election is not made, any foreign taxes paid or accrued will
          represent an expense to each Portfolio which will reduce its
          investment company taxable income.

          Because Shares of the Portfolios can only be purchased through
          qualified plans, it is anticipated that any income dividends or
          capital gains distributions will be exempt from current taxation if
          left to accumulate within such plans. See the plan documents for
          additional information.

                                                                              39

Principal shareholders


          The officers and Trustees of the Portfolios cannot directly own Shares
          of the Portfolios without purchasing through a qualified plan. As a
          result, such officers and Trustees as a group own less than 1% of the
          outstanding Shares of each Portfolio. As of April 3, 2000, all of the
          outstanding Shares of the Portfolios were owned by qualified plans and
          by Janus Capital, which provided seed capital for the Portfolios. The
          percentage ownership of each qualified plan owning more than 5% of the
          Shares of any Portfolio is as follows:

Miscellaneous information


          Each Portfolio is a series of the Trust, an open-end management
          investment company registered under the 1940 Act and organized as a
          Delaware business trust on May 20, 1993. As of the date of this SAI,
          the Trust is offering fourteen series of shares, known as
          "Portfolios," each of which consists of two or three classes of
          shares. Additional series and/or classes may be created from time to
          time.


SHARES OF THE TRUST

          The Trust is authorized to issue an unlimited number of shares of
          beneficial interest with a par value of $.001 per share for each
          series of the Trust. Shares of each Portfolio are fully paid and
          nonassessable when issued. Shares of a Portfolio participate equally
          in dividends and other distributions by the shares of such Portfolio,
          and in residual assets of that Portfolio in the event of liquidation.
          Shares of each Portfolio have no preemptive, conversion or
          subscription rights.


          The Portfolios each offer two or three classes of shares. The Shares
          discussed in this SAI are offered only to qualified plans whose
          service providers require a fee from the Trust assets for providing
          certain services to plan participants. A second class of shares,
          Institutional Shares, is offered only in connection with investments
          in and payments under variable insurance contracts as well as other
          qualified retirement plans.


SHAREHOLDER MEETINGS

          The Trust does not intend to hold annual shareholder meetings.
          However, special meetings may be called for a specific Portfolio or
          for the Trust as a whole for purposes such as electing or removing
          Trustees, terminating or reorganizing the Trust, changing fundamental
          policies, or for any other purpose requiring a shareholder vote under
          the 1940 Act. Separate votes are taken by each Portfolio or class only
          if a matter affects or requires the vote of only that Portfolio or
          class or that Portfolio's or class' interest in the matter differs
          from the interest of other Portfolios of the Trust. A shareholder is
          entitled to one vote for each Share owned.

VOTING RIGHTS

          The Trustees are responsible for major decisions relating to each
          Portfolio's policies and objectives; the Trustees oversee the
          operation of each Portfolio by its officers and review the investment
          decisions of the officers.

          The present Trustees were elected by the initial trustee of the Trust
          on May 25, 1993, and were approved by the initial shareholder on May
          25, 1993, with the exception of Mr. Craig and Mr. Rothe who were
          appointed by the Trustees as of June 30, 1995 and as of January 1,
          1997, respectively. Under the Trust Instrument, each Trustee will
          continue in office until the termination of the Trust or his earlier
          death, retirement, resignation, bankruptcy, incapacity or removal.
          Vacancies will be filled by a majority of the remaining Trustees,
          subject to the 1940 Act. Therefore, no annual or regular meetings of
          shareholders normally will be held, unless otherwise required by the
          Trust Instrument or the 1940 Act. Subject to the foregoing,
          shareholders have the power to vote to elect or remove Trustees, to
          terminate or reorganize their Portfolio, to amend the Trust
          Instrument, to bring certain derivative actions and on any other
          matters on which a shareholder vote is required by the 1940 Act, the
          Trust Instrument, the Trust's Bylaws or the Trustees.

          As mentioned above in "Shareholder Meetings," each share of each
          portfolio of the Trust has one vote (and fractional votes for
          fractional shares). Shares of all portfolios of the Trust have
          noncumulative voting rights, which means that the holders of more than
          50% of the shares of all series of the Trust voting for the election
          of Trustees can elect 100% of the Trustees if they choose to do so
          and, in such event, the holders of the remaining shares will not be
          able to elect any Trustees.

                                                                              43

REGISTRATION STATEMENT

          Statement under the Securities Act of 1933, as amended, with respect
          to the securities to which this SAI relates. If further information is
          desired with respect to the Portfolios or such securities, reference
          is made to the Registration Statement and the exhibits filed as a part
          thereof.

Performance information


          Quotations of average annual total return for the Shares of a
          Portfolio will be expressed in terms of the average annual compounded
          rate of return of a hypothetical investment in the Shares of such
          Portfolio over periods of 1, 5, and 10 years (up to the life of the
          Portfolio). These are the annual total rates of return that would
          equate the initial amount invested to the ending redeemable value.
          These rates of return are calculated pursuant to the following
          formula: P(1 + T)(n) = ERV (where P = a hypothetical initial payment
          of $1,000, T = the average annual total return, n = the number of
          years and ERV = the ending redeemable value of a hypothetical $1,000
          payment made at the beginning of the period). All total return figures
          reflect the deduction of a proportional share of expenses of the
          Shares of a Portfolio on an annual basis, and assume that all
          dividends and distributions are reinvested when paid. The average
          annual total return of the Shares of each Portfolio, computed as of
          December 31, 1999, is shown in the table below.


          The Growth, Aggressive Growth, International Growth, Worldwide Growth,
          Balanced, Flexible Income, and High-Yield Portfolios Retirement Shares
          commenced operations on May 1, 1997. The returns shown for the
          Retirement Shares of these Portfolios reflect the historical
          performance of a different class of shares (the Institutional Shares)
          prior to May 1, 1997, restated based on the Retirement Shares' fees
          and expenses on May 1, 1997 (ignoring any fee and expense
          limitations).

          Yield quotations for a Portfolio's Shares are based on the investment
          income per Share earned during a particular 30-day period (including
          dividends, if any, and interest), less expenses accrued during the
          period ("net investment income"), and are computed by dividing net
          investment income by the net asset value per share on the last day of
          the period, according to the following formula:

                              YIELD = 2[(a - b + 1)(6) - 1]
                                         -----
                                          cd

          where a = dividend and interest income
                b = expenses accrued for the period (net of reimbursements)
                c = average daily number of shares outstanding during the period
                    that were entitled to receive dividends
                d = maximum net asset value per share on the last day of the
                    period

Appendix A

EXPLANATION OF RATING CATEGORIES

          The following is a description of credit ratings issued by two of the
          major credit ratings agencies. Credit ratings evaluate only the safety
          of principal and interest payments, not the market value risk of lower
          quality securities. Credit rating agencies may fail to change credit
          ratings to reflect subsequent events on a timely basis. Although Janus
          Capital considers security ratings when making investment decisions,
          it also performs its own investment analysis and does not rely solely
          on the ratings assigned by credit agencies.

                Investment Grade
                AAA......................... Highest rating; extremely strong capacity to pay principal
                                             and interest.
                AA.......................... High quality; very strong capacity to pay principal and
                                             interest.
                A........................... Strong capacity to pay principal and interest; somewhat more
                                             susceptible to the adverse effects of changing circumstances
                                             and economic conditions.
                BBB......................... Adequate capacity to pay principal and interest; normally
                                             exhibit adequate protection parameters, but adverse economic
                                             conditions or changing circumstances more likely to lead to
                                             a weakened capacity to pay principal and interest than for
                                             higher rated bonds.
                Non-Investment Grade
                BB, B, CCC, CC, C........... Predominantly speculative with respect to the issuer's
                                             capacity to meet required interest and principal payments.
                                             BB -- lowest degree of speculation; C -- the highest degree
                                             of speculation. Quality and protective characteristics
                                             outweighed by large uncertainties or major risk exposure to
                                             adverse conditions.
                D........................... In default.

                Investment Grade
                Aaa......................... Highest quality, smallest degree of investment risk.
                Aa.......................... High quality; together with Aaa bonds, they compose the
                                             high-grade bond group.
                A........................... Upper-medium grade obligations; many favorable investment
                                             attributes.
                Baa......................... Medium-grade obligations; neither highly protected nor
                                             poorly secured. Interest and principal appear adequate for
                                             the present but certain protective elements may be lacking
                                             or may be unreliable over any great length of time.
                Non-Investment Grade
                Ba.......................... More uncertain, with speculative elements. Protection of
                                             interest and principal payments not well safeguarded during
                                             good and bad times.
                B........................... Lack characteristics of desirable investment; potentially
                                             low assurance of timely interest and principal payments or
                                             maintenance of other contract terms over time.
                Caa......................... Poor standing, may be in default; elements of danger with
                                             respect to principal or interest payments.
                Ca.......................... Speculative in a high degree; could be in default or have
                                             other marked shortcomings.
                C........................... Lowest-rated; extremely poor prospects of ever attaining
                                             investment standing.

          Unrated securities will be treated as noninvestment grade securities
          unless the portfolio manager determines that such securities are the
          equivalent of investment grade securities. Securities that have
          received ratings from more than one agency are considered investment
          grade if at least one agency has rated the security investment grade.

                              May 1, 2000



                 This Statement of Additional Information expands upon and
                 supplements the information contained in the current Prospectus
                 for the Service Shares (the "Shares") of the portfolios listed
                 above, each of which is a separate series of Janus Aspen
                 Series, a Delaware business trust. Each of these series of the
                 Trust represents shares of beneficial interest in a separate
                 portfolio of securities and other assets with its own objective
                 and policies. Each Portfolio is managed separately by Janus
                 Capital Corporation.


                 The Service Shares of the Portfolios may be purchased only by
                 separate accounts of insurance companies for the purpose of
                 funding variable life insurance policies and variable annuity
                 contracts (collectively, "variable insurance contracts") and by
                 certain qualified retirement plans.


                 This SAI is not a Prospectus and should be read in conjunction
                 with the Portfolios' Prospectus dated May 1, 2000, which is
                 incorporated by reference into this SAI and may be obtained
                 from your insurance company or plan sponsor. This SAI contains
                 additional and more detailed information about the Portfolios'
                 operations and activities than the Prospectus. The Annual
                 Reports, which contain important financial information about
                 the Portfolios, are incorporated by reference into this SAI and

CLASSIFICATION


          Each Portfolio is a series of the Trust, an open-end, management
          investment company. The Investment Company Act of 1940 ("1940 Act")
          classifies mutual funds as either diversified or nondiversified.
          Aggressive Growth Portfolio, Capital Appreciation Portfolio, Global
          Life Sciences Portfolio and Global Technology Portfolio are
          nondiversified funds. Each of these Portfolios reserves the right to
          become a diversified fund by limiting the investments in which more
          than 5% of its total assets are invested. Growth Portfolio, Balanced
          Portfolio, Equity Income Portfolio, Growth and Income Portfolio,
          International Growth Portfolio, Worldwide Growth Portfolio, Flexible
          Income Portfolio and High-Yield Portfolio are diversified funds.


PORTFOLIO TURNOVER

          The Prospectus includes a discussion of portfolio turnover policies.
          Portfolio turnover is calculated by dividing total purchases or sales,
          whichever is less, by the average monthly value of a Portfolio's
          securities. The following table summarizes the portfolio turnover
          rates for the fiscal periods indicated. The information below is for
          fiscal years ended December 31.

INVESTMENT POLICIES AND RESTRICTIONS APPLICABLE TO ALL PORTFOLIOS

          The Portfolios are subject to certain fundamental policies and
          restrictions that may not be changed without shareholder approval.
          Shareholder approval means approval by the lesser of (i) more than 50%
          of the outstanding voting securities of the Trust (or a particular
          Portfolio or particular class of shares if a matter affects just that
          Portfolio or that class of shares), or (ii) 67% or more of the voting
          securities present at a meeting if the holders of more than 50% of the
          outstanding voting securities of the Trust (or a particular Portfolio
          or class of shares) are present or represented by proxy. As
          fundamental policies, each of the Portfolios may not:


          (1) Own more than 10% of the outstanding voting securities of any one
          issuer and, as to fifty percent (50%) of the value of the total assets
          of Aggressive Growth Portfolio, Capital Appreciation Portfolio, Global
          Life Sciences Portfolio and Global Technology Portfolio and as to
          seventy-five percent (75%) of the value of the total assets of the
          other Portfolios, purchase the securities of any one issuer (except
          cash items and "government securities" as defined under the Investment
          Company Act of 1940, as amended, if immediately after and as a result
          of such purchase, the value of the holdings of a Portfolio in the
          securities of such issuer exceeds 5% of the value of such Portfolio's
          total assets. With respect to the other 50% of the


 2
<PAGE>


          value of its total assets, Aggressive Growth Portfolio, Capital
          Appreciation Portfolio, Global Life Sciences Portfolio and Global
          Technology Portfolio may invest in the securities of as few as two
          issuers.



          (2) Invest 25% or more of the value of their respective total assets
          in any particular industry (other than U.S. government securities).
          This policy does not apply to Global Life Sciences Portfolio or Global
          Technology Portfolio.


          (3) Invest directly in real estate or interests in real estate;
          however, the Portfolios may own debt or equity securities issued by
          companies engaged in those businesses.

          (4) Purchase or sell physical commodities other than foreign
          currencies unless acquired as a result of ownership of securities (but
          this limitation shall not prevent the Portfolios from purchasing or
          selling options, futures, swaps and forward contracts or from
          investing in securities or other instruments backed by physical
          commodities).

          (5) Lend any security or make any other loan if, as a result, more
          than 25% of a Portfolio's total assets would be lent to other parties
          (but this limitation does not apply to purchases of commercial paper,
          debt securities or repurchase agreements).

          (6) Act as an underwriter of securities issued by others, except to
          the extent that a Portfolio may be deemed an underwriter in connection
          with the disposition of its portfolio securities.

          As a fundamental policy, each Portfolio may, notwithstanding any other
          investment policy or limitation (whether or not fundamental), invest
          all of its assets in the securities of a single open-end management
          investment company with substantially the same fundamental investment
          objective, policies and limitations as such Portfolio.

          The Trustees have adopted additional investment restrictions for the
          Portfolios. These restrictions are operating policies of the
          Portfolios and may be changed by the Trustees without shareholder
          approval. The additional investment restrictions adopted by the
          Trustees to date include the following:

          (a) A Portfolio will not (i) enter into any futures contracts and
          related options for purposes other than bona fide hedging transactions
          within the meaning of Commodity Futures Trading Commission ("CFTC")
          regulations if the aggregate initial margin and premiums required to
          establish positions in futures contracts and related options that do
          not fall within the definition of bona fide hedging transactions will
          exceed 5% of the fair market value of a Portfolio's net assets, after
          taking into account unrealized profits and unrealized losses on any
          such contracts it has entered into; and (ii) enter into any futures
          contracts if the aggregate amount of such Portfolio's commitments
          under outstanding futures contracts positions would exceed the market
          value of its total assets.

          (b) The Portfolios do not currently intend to sell securities short,
          unless they own or have the right to obtain securities equivalent in
          kind and amount to the securities sold short without the payment of
          any additional consideration therefor, and provided that transactions
          in futures, options, swaps and forward contracts are not deemed to
          constitute selling securities short.

          (c) The Portfolios do not currently intend to purchase securities on
          margin, except that the Portfolios may obtain such short-term credits
          as are necessary for the clearance of transactions, and provided that
          margin payments and other deposits in connection with transactions in
          futures, options, swaps and forward contracts shall not be deemed to
          constitute purchasing securities on margin.

          (d) A Portfolio may not mortgage or pledge any securities owned or
          held by such Portfolio in amounts that exceed, in the aggregate, 15%
          of that Portfolio's net asset value, provided that this limitation
          does not

                                                                               3

          apply to reverse repurchase agreements, deposits of assets to margin,
          guarantee positions in futures, options, swaps or forward contracts,
          or the segregation of assets in connection with such contracts.

          (e) The Portfolios may borrow money for temporary or emergency
          purposes (not for leveraging or investment) in an amount not exceeding
          25% of the value of their respective total assets (including the
          amount borrowed) less liabilities (other than borrowings). If
          borrowings exceed 25% of the value of a Portfolio's total assets by
          reason of a decline in net assets, the Portfolio will reduce its
          borrowings within three business days to the extent necessary to
          comply with the 25% limitation. This policy shall not prohibit reverse
          repurchase agreements, deposits of assets to margin or guarantee
          positions in futures, options, swaps or forward contracts, or the
          segregation of assets in connection with such contracts.

          (f) The Portfolios do not currently intend to purchase any security or
          enter into a repurchase agreement, if as a result, more than 15% of
          their respective net assets would be invested in repurchase agreements
          not entitling the holder to payment of principal and interest within
          seven days and in securities that are illiquid by virtue of legal or
          contractual restrictions on resale or the absence of a readily
          available market. The Trustees, or the Portfolios' investment adviser
          acting pursuant to authority delegated by the Trustees, may determine
          that a readily available market exists for securities eligible for
          resale pursuant to Rule 144A under the Securities Act of 1933 ("Rule
          144A Securities"), or any successor to such rule, Section 4(2)
          commercial paper and municipal lease obligations. Accordingly, such
          securities may not be subject to the foregoing limitation.

          (g) The Portfolios may not invest in companies for the purpose of
          exercising control of management.

          Under the terms of an exemptive order received from the Securities and
          Exchange Commission ("SEC"), each of the Portfolios may borrow money
          from or lend money to other funds that permit such transactions and
          for which Janus Capital serves as investment adviser. All such
          borrowing and lending will be subject to the above limits. A Portfolio
          will borrow money through the program only when the costs are equal to
          or lower than the cost of bank loans. Interfund loans and borrowings
          normally extend overnight, but can have a maximum duration of seven
          days. A Portfolio will lend through the program only when the returns
          are higher than those available from other short-term instruments
          (such as repurchase agreements). A Portfolio may have to borrow from a
          bank at a higher interest rate if an interfund loan is called or not
          renewed. Any delay in repayment to a lending Portfolio could result in
          a lost investment opportunity or additional borrowing costs.

          For the purposes of these investment restrictions, the identification
          of the issuer of a municipal obligation depends on the terms and
          conditions of the security. When assets and revenues of a political
          subdivision are separate from those of the government that created the
          subdivision and the security is backed only by the assets and revenues
          of the subdivision, the subdivision is deemed to be the sole issuer.
          Similarly, in the case of an industrial development bond, if the bond
          is backed only by assets and revenues of a nongovernmental user, then
          the nongovernmental user would be deemed to be the sole issuer. If,
          however, in either case, the creating government or some other entity
          guarantees the security, the guarantee would be considered a separate
          security that would be treated as an issue of the guaranteeing entity.

          For purposes of the Portfolios' restriction on investing in a
          particular industry, the Portfolios will rely primarily on industry
          classifications as published by Bloomberg L.P. To the extent that
          Bloomberg L.P. classifications are so broad that the primary economic
          characteristics in a single class are materially different, the
          Portfolios may further classify issuers in accordance with industry
          classifications as published by the SEC.

INVESTMENT POLICIES APPLICABLE TO CERTAIN PORTFOLIOS

          BALANCED PORTFOLIO. As an operational policy, at least 25% of the
          assets of Balanced Portfolio normally will be invested in fixed-income
          securities.


          GLOBAL LIFE SCIENCES PORTFOLIO. As a fundamental policy, Global Life
          Sciences Portfolio will normally invest at least 25% of its total
          assets, in the aggregate, in the following industry groups: health
          care; pharmaceuticals; agriculture; cosmetics/personal care; and
          biotechnology.


          FLEXIBLE INCOME PORTFOLIO. As a fundamental policy, this Portfolio may
          not purchase a non-income-producing security if, after such purchase,
          less than 80% of the Portfolio's total assets would be invested in
          income-producing securities. Income-producing securities include
          securities that make periodic interest payments as well as those that
          make interest payments on a deferred basis or pay interest only at
          maturity (e.g., Treasury bills or zero coupon bonds).

INVESTMENT STRATEGIES AND RISKS

Cash Position


          As discussed in the Prospectus, when a portfolio manager believes that
          market conditions are unfavorable for profitable investing, or when he
          or she is otherwise unable to locate attractive investment
          opportunities, the Portfolio's investment in cash and similar
          investments may increase. Securities that the Portfolios may invest in
          as a means of receiving a return on idle cash include commercial
          paper, certificates of deposit, repurchase agreements or other
          short-term debt obligations. The Portfolios may also invest in money
          market funds, including funds managed by Janus Capital. (See
          "Investment Company Securities" on page 8).


Illiquid Investments

          Each Portfolio may invest up to 15% of its net assets in illiquid
          investments (i.e., securities that are not readily marketable). The
          Trustees have authorized Janus Capital to make liquidity
          determinations with respect to certain securities, including Rule 144A
          Securities, commercial paper and municipal lease obligations purchased
          by the Portfolios. Under the guidelines established by the Trustees,
          Janus Capital will consider the following factors: (1) the frequency
          of trades and quoted prices for the obligation; (2) the number of
          dealers willing to purchase or sell the security and the number of
          other potential purchasers; (3) the willingness of dealers to
          undertake to make a market in the security; and (4) the nature of the
          security and the nature of the marketplace trades, including the time
          needed to dispose of the security, the method of soliciting offers and
          the mechanics of the transfer. In the case of commercial paper, Janus
          Capital will also consider whether the paper is traded flat or in
          default as to principal and interest and any ratings of the paper by a
          nationally recognized statistical rating organization ("NRSRO"). A
          foreign security that may be freely traded on or through the
          facilities of an offshore exchange or other established offshore
          securities market is not deemed to be a restricted security subject to
          these procedures.

          If illiquid securities exceed 15% of a Portfolio's net assets after
          the time of purchase the Portfolio will take steps to reduce in an
          orderly fashion its holdings of illiquid securities. Because illiquid
          securities may not be readily marketable, a portfolio manager may not
          be able to dispose of them in a timely manner. As a result, a
          Portfolio may be forced to hold illiquid securities while their price
          depreciates. Depreciation in the price of illiquid securities may
          cause the net asset value of a Portfolio to decline.

                                                                               5
<PAGE>


Securities Lending



          The Portfolios may lend securities to qualified parties (typically
          brokers or other financial institutions) who need to borrow securities
          in order to complete certain transactions such as covering short
          sales, avoiding failures to deliver securities or completing arbitrage
          activities. The Portfolios may seek to earn additional income through
          securities lending. Since there is the risk of delay in recovering a
          loaned security or the risk of loss in collateral rights if the
          borrower fails financially, securities lending will only be made to
          parties that Janus Capital deems creditworthy and in good standing. In
          addition, such loans will only be made if Janus Capital believes the
          benefit from granting such loans justifies the risk. The Portfolios
          will not have the right to vote on securities while they are being
          lent, but it will generally call a loan in anticipation of any
          important vote. All loans will be continuously secured by collateral
          which consists of cash, U.S. government securities, letters of credit
          and such other collateral permitted by the SEC and policies approved
          by the Trustees. Cash collateral may be invested in money market funds
          advised by Janus to the extent consistent with exemptive relief
          obtained from the SEC.


Short Sales

          Each Portfolio may engage in "short sales against the box." This
          technique involves selling either a security that a Portfolio owns, or
          a security equivalent in kind and amount to the security sold short
          that the Portfolio has the right to obtain, for delivery at a
          specified date in the future. A Portfolio may enter into a short sale
          against the box to hedge against anticipated declines in the market
          price of portfolio securities. If the value of the securities sold
          short increases prior to the scheduled delivery date, a Portfolio
          loses the opportunity to participate in the gain.

Zero Coupon, Step Coupon and Pay-In-Kind Securities

          Each Portfolio may invest up to 10% (without limit for High-Yield
          Portfolio and Flexible Income Portfolio) of its assets in zero coupon,
          pay-in-kind and step coupon securities. Zero coupon bonds are issued
          and traded at a discount from their face value. They do not entitle
          the holder to any periodic payment of interest prior to maturity. Step
          coupon bonds trade at a discount from their face value and pay coupon
          interest. The coupon rate is low for an initial period and then
          increases to a higher coupon rate thereafter. The discount from the
          face amount or par value depends on the time remaining until cash
          payments begin, prevailing interest rates, liquidity of the security
          and the perceived credit quality of the issuer. Pay-in-kind bonds
          normally give the issuer an option to pay cash at a coupon payment
          date or give the holder of the security a similar bond with the same
          coupon rate and a face value equal to the amount of the coupon payment
          that would have been made. For the purposes of any Portfolio's
          restriction on investing in income-producing securities,
          income-producing securities include securities that make periodic
          interest payments as well as those that make interest payments on a
          deferred basis or pay interest only at maturity (e.g., Treasury bills
          or zero coupon bonds).

          Current federal income tax law requires holders of zero coupon
          securities and step coupon securities to report the portion of the
          original issue discount on such securities that accrues during a given
          year as interest income, even though the holders receive no cash
          payments of interest during the year. In order to qualify as a
          "regulated investment company" under the Internal Revenue Code of 1986
          and the regulations thereunder (the "Code"), a Portfolio must
          distribute its investment company taxable income, including the
          original issue discount accrued on zero coupon or step coupon bonds.
          Because a Portfolio will not receive cash payments on a current basis
          in respect of accrued original-issue discount on zero coupon bonds or
          step coupon bonds during the period before interest payments begin, in
          some years that Portfolio may have to distribute cash obtained from
          other sources in order to satisfy the distribution requirements under
          the Code. A Portfolio might obtain such cash from selling other
          portfolio holdings which might cause that

 6
<PAGE>

          Portfolio to incur capital gains or losses on the sale. Additionally,
          these actions are likely to reduce the assets to which Portfolio
          expenses could be allocated and to reduce the rate of return for that
          Portfolio. In some circumstances, such sales might be necessary in
          order to satisfy cash distribution requirements even though investment
          considerations might otherwise make it undesirable for a Portfolio to
          sell the securities at the time.

          Generally, the market prices of zero coupon, step coupon and
          pay-in-kind securities are more volatile than the prices of securities
          that pay interest periodically and in cash and are likely to respond
          to changes in interest rates to a greater degree than other types of
          debt securities having similar maturities and credit quality.

Pass-Through Securities

          The Portfolios may invest in various types of pass-through securities,
          such as mortgage-backed securities, asset-backed securities and
          participation interests. A pass-through security is a share or
          certificate of interest in a pool of debt obligations that have been
          repackaged by an intermediary, such as a bank or broker-dealer. The
          purchaser of a pass-through security receives an undivided interest in
          the underlying pool of securities. The issuers of the underlying
          securities make interest and principal payments to the intermediary
          which are passed through to purchasers, such as the Portfolios. The
          most common type of pass-through securities are mortgage-backed
          securities. Government National Mortgage Association ("GNMA")
          Certificates are mortgage-backed securities that evidence an undivided
          interest in a pool of mortgage loans. GNMA Certificates differ from
          bonds in that principal is paid back monthly by the borrowers over the
          term of the loan rather than returned in a lump sum at maturity. A
          Portfolio will generally purchase "modified pass-through" GNMA
          Certificates, which entitle the holder to receive a share of all
          interest and principal payments paid and owned on the mortgage pool,
          net of fees paid to the "issuer" and GNMA, regardless of whether or
          not the mortgagor actually makes the payment. GNMA Certificates are
          backed as to the timely payment of principal and interest by the full
          faith and credit of the U.S. government.

          The Federal Home Loan Mortgage Corporation ("FHLMC") issues two types
          of mortgage pass-through securities: mortgage participation
          certificates ("PCs") and guaranteed mortgage certificates ("GMCs").
          PCs resemble GNMA Certificates in that each PC represents a pro rata
          share of all interest and principal payments made and owned on the
          underlying pool. FHLMC guarantees timely payments of interest on PCs
          and the full return of principal. GMCs also represent a pro rata
          interest in a pool of mortgages. However, these instruments pay
          interest semiannually and return principal once a year in guaranteed
          minimum payments. This type of security is guaranteed by FHLMC as to
          timely payment of principal and interest but it is not guaranteed by
          the full faith and credit of the U.S. government.

          The Federal National Mortgage Association ("FNMA") issues guaranteed
          mortgage pass-through certificates ("FNMA Certificates"). FNMA
          Certificates resemble GNMA Certificates in that each FNMA Certificate
          represents a pro rata share of all interest and principal payments
          made and owned on the underlying pool. This type of security is
          guaranteed by FNMA as to timely payment of principal and interest but
          it is not guaranteed by the full faith and credit of the U.S.
          government.

          Except for GMCs, each of the mortgage-backed securities described
          above is characterized by monthly payments to the holder, reflecting
          the monthly payments made by the borrowers who received the underlying
          mortgage loans. The payments to the security holders (such as the
          Portfolios), like the payments on the underlying loans, represent both
          principal and interest. Although the underlying mortgage loans are for
          specified periods of time, such as 20 or 30 years, the borrowers can,
          and typically do, pay

                                                                               7
<PAGE>

          them off sooner. Thus, the security holders frequently receive
          prepayments of principal in addition to the principal that is part of
          the regular monthly payments. A portfolio manager will consider
          estimated prepayment rates in calculating the average-weighted
          maturity of a Portfolio. A borrower is more likely to prepay a
          mortgage that bears a relatively high rate of interest. This means
          that in times of declining interest rates, higher yielding
          mortgage-backed securities held by a Portfolio might be converted to
          cash and that Portfolio will be forced to accept lower interest rates
          when that cash is used to purchase additional securities in the
          mortgage-backed securities sector or in other investment sectors.
          Additionally, prepayments during such periods will limit a Portfolio's
          ability to participate in as large a market gain as may be experienced
          with a comparable security not subject to prepayment.

          Asset-backed securities represent interests in pools of consumer loans
          and are backed by paper or accounts receivables originated by banks,
          credit card companies or other providers of credit. Generally, the
          originating bank or credit provider is neither the obligor nor the
          guarantor of the security, and interest and principal payments
          ultimately depend upon payment of the underlying loans by individuals.
          Tax-exempt asset-backed securities include units of beneficial
          interests in pools of purchase contracts, financing leases, and sales
          agreements that may be created when a municipality enters into an
          installment purchase contract or lease with a vendor. Such securities
          may be secured by the assets purchased or leased by the municipality;
          however, if the municipality stops making payments, there generally
          will be no recourse against the vendor. The market for tax-exempt
          asset-backed securities is still relatively new. These obligations are
          likely to involve unscheduled prepayments of principal.

Investment Company Securities

          From time to time, the Portfolios may invest in securities of other
          investment companies, subject to the provisions of Section 12(d)(1) of
          the 1940 Act. The Portfolios may invest in securities of money market
          funds managed by Janus Capital in excess of the limitations of Section
          12(d)(1) under the terms of an SEC exemptive order obtained by Janus
          Capital and the Janus funds.

Depositary Receipts


          The Portfolios may invest in sponsored and unsponsored American
          Depositary Receipts ("ADRs"), which are receipts issued by an American
          bank or trust company evidencing ownership of underlying securities
          issued by a foreign issuer. ADRs, in registered form, are designed for
          use in U.S. securities markets. Unsponsored ADRs may be created
          without the participation of the foreign issuer. Holders of these ADRs
          generally bear all the costs of the ADR facility, whereas foreign
          issuers typically bear certain costs in a sponsored ADR. The bank or
          trust company depositary of an unsponsored ADR may be under no
          obligation to distribute shareholder communications received from the
          foreign issuer or to pass through voting rights. The Portfolios may
          also invest in European Depositary Receipts ("EDRs"), Global
          Depositary Receipts ("GDRs") and in other similar instruments
          representing securities of foreign companies. EDRs and GDRs are
          securities that are typically issued by foreign banks or foreign trust
          companies, although U.S. banks or U.S. trust companies may issue them.
          EDRs and GDRs are structured similarly to the arrangements of ADRs.
          EDRs, in bearer form, are designed for use in European securities
          markets.



          Depositary Receipts are generally subject to the same sort of risks as
          direct investments in a foreign country, such as, currency risk,
          political and economic risk, and market risk, because their values
          depend on the performance of a foreign security denominated in its
          home currency. The risks of foreign investing are addressed in some
          detail in the Portfolios' prospectus.

Municipal Obligations

          The Portfolios may invest in municipal obligations issued by states,
          territories and possessions of the United States and the District of
          Columbia. The value of municipal obligations can be affected by
          changes in their actual or perceived credit quality. The credit
          quality of municipal obligations can be affected by, among other
          things, the financial condition of the issuer or guarantor, the
          issuer's future borrowing plans and sources of revenue, the economic
          feasibility of the revenue bond project or general borrowing purpose,
          political or economic developments in the region where the security is
          issued, and the liquidity of the security. Because municipal
          securities are generally traded over-the-counter, the liquidity of a
          particular issue often depends on the willingness of dealers to make a
          market in the security. The liquidity of some municipal obligations
          may be enhanced by demand features, which would enable a Portfolio to
          demand payment on short notice from the issuer or a financial
          intermediary.

Other Income-Producing Securities

          Other types of income producing securities that the Portfolios may
          purchase include, but are not limited to, the following types of
          securities:

          VARIABLE AND FLOATING RATE OBLIGATIONS. These types of securities have
          variable or floating rates of interest and, under certain limited
          circumstances, may have varying principal amounts. These securities
          pay interest at rates that are adjusted periodically according to a
          specified formula, usually with reference to some interest rate index
          or market interest rate. The floating rate tends to decrease the
          security's price sensitivity to changes in interest rates. These types
          of securities are relatively long-term instruments that often carry
          demand features permitting the holder to demand payment of principal
          at any time or at specified intervals prior to maturity.

          In order to most effectively use these investments, a portfolio
          manager must correctly assess probable movements in interest rates.
          This involves different skills than those used to select most
          portfolio securities. If the portfolio manager incorrectly forecasts
          such movements, a Portfolio could be adversely affected by the use of
          variable or floating rate obligations.

          STANDBY COMMITMENTS. These instruments, which are similar to a put,
          give a Portfolio the option to obligate a broker, dealer or bank to
          repurchase a security held by that Portfolio at a specified price.

          TENDER OPTION BONDS. Tender option bonds are relatively long-term
          bonds that are coupled with the agreement of a third party (such as a
          broker, dealer or bank) to grant the holders of such securities the
          option to tender the securities to the institution at periodic
          intervals.

          INVERSE FLOATERS. Inverse floaters are debt instruments whose interest
          bears an inverse relationship to the interest rate on another
          security. No Portfolio will invest more than 5% of its assets in
          inverse floaters. Similar to variable and floating rate obligations,
          effective use of inverse floaters requires skills different from those
          needed to select most portfolio securities. If movements in interest
          rates are incorrectly anticipated, a fund could lose money or its NAV
          could decline by the use of inverse floaters.

          STRIP BONDS. Strip bonds are debt securities that are stripped of
          their interest (usually by a financial intermediary) after the
          securities are issued. The market value of these securities generally
          fluctuates more in response to changes in interest rates than
          interest-paying securities of comparable maturity.

          The Portfolios will purchase standby commitments, tender option bonds
          and instruments with demand features primarily for the purpose of
          increasing the liquidity of their holdings.

                                                                               9

Repurchase and Reverse Repurchase Agreements

          In a repurchase agreement, a Portfolio purchases a security and
          simultaneously commits to resell that security to the seller at an
          agreed upon price on an agreed upon date within a number of days
          (usually not more than seven) from the date of purchase. The resale
          price consists of the purchase price plus an agreed upon incremental
          amount that is unrelated to the coupon rate or maturity of the
          purchased security. A repurchase agreement involves the obligation of
          the seller to pay the agreed upon price, which obligation is in effect
          secured by the value (at least equal to the amount of the agreed upon
          resale price and marked-to-market daily) of the underlying security or
          "collateral." A risk associated with repurchase agreements is the
          failure of the seller to repurchase the securities as agreed, which
          may cause a Portfolio to suffer a loss if the market value of such
          securities declines before they can be liquidated on the open market.
          In the event of bankruptcy or insolvency of the seller, a Portfolio
          may encounter delays and incur costs in liquidating the underlying
          security. Repurchase agreements that mature in more than seven days
          are subject to the 15% limit on illiquid investments. While it is not
          possible to eliminate all risks from these transactions, it is the
          policy of the Portfolios to limit repurchase agreements to those
          parties whose creditworthiness has been reviewed and found
          satisfactory by Janus Capital.

          A Portfolio may use reverse repurchase agreements to obtain cash to
          satisfy unusually heavy redemption requests or for other temporary or
          emergency purposes without the necessity of selling portfolio
          securities, or to earn additional income on portfolio securities, such
          as Treasury bills or notes. In a reverse repurchase agreement, a
          Portfolio sells a portfolio security to another party, such as a bank
          or broker-dealer, in return for cash and agrees to repurchase the
          instrument at a particular price and time. While a reverse repurchase
          agreement is outstanding, a Portfolio will maintain cash and
          appropriate liquid assets in a segregated custodial account to cover
          its obligation under the agreement. The Portfolios will enter into
          reverse repurchase agreements only with parties that Janus Capital
          deems creditworthy. Using reverse repurchase agreements to earn
          additional income involves the risk that the interest earned on the
          invested proceeds is less than the expense of the reverse repurchase
          agreement transaction. This technique may also have a leveraging
          effect on the Portfolio, although the Portfolio's intent to segregate
          assets in the amount of the reverse repurchase agreement minimizes
          this effect.


High-Yield/High-Risk Bonds



          Flexible Income Portfolio and High-Yield Portfolio may invest without
          limit in bonds that are rated below investment grade (e.g., bonds
          rated BB or lower by Standard & Poor's Ratings Services or Ba or lower
          by Moody's Investors Service, Inc.). No other Portfolio intends to
          invest 35% or more of its net assets in such bonds. Lower rated bonds
          involve a higher degree of credit risk, which is the risk that the
          issuer will not make interest or principal payments when due. In the
          event of an unanticipated default, a Portfolio would experience a
          reduction in its income, and could expect a decline in the market
          value of the bonds so affected.



          Any Portfolio may also invest in unrated bonds of foreign and domestic
          issuers. Unrated bonds, while not necessarily of lower quality than
          rated bonds, may not have as broad a market. Because of the size and
          perceived demand of the issue, among other factors, certain
          municipalities may not incur the costs of obtaining a rating. A
          Portfolio's manager will analyze the creditworthiness of the issuer,
          as well as any financial institution or other party responsible for
          payments on the bond, in determining whether to purchase unrated
          municipal bonds. Unrated bonds will be included in the 35% limit of
          each Portfolio unless its manager deems such securities to be the
          equivalent of investment grade bonds.


          Subject to the above limits, each Portfolio may purchase defaulted
          securities only when its portfolio manager believes, based upon
          analysis of the financial condition, results of operations and
          economic

 10
<PAGE>

          outlook of an issuer, that there is potential for resumption of income
          payments and that the securities offer an unusual opportunity for
          capital appreciation. Notwithstanding the portfolio manager's belief
          about the resumption of income, however, the purchase of any security
          on which payment of interest or dividends is suspended involves a high
          degree of risk. Such risk includes, among other things, the following:

          FINANCIAL AND MARKET RISKS. Investments in securities that are in
          default involve a high degree of financial and market risks that can
          result in substantial or, at times, even total losses. Issuers of
          defaulted securities may have substantial capital needs and may become
          involved in bankruptcy or reorganization proceedings. Among the
          problems involved in investments in such issuers is the fact that it
          may be difficult to obtain information about the condition of such
          issuers. The market prices of such securities also are subject to
          abrupt and erratic movements and above average price volatility, and
          the spread between the bid and asked prices of such securities may be
          greater than normally expected.

          DISPOSITION OF PORTFOLIO SECURITIES. Although these Portfolios
          generally will purchase securities for which their portfolio managers
          expect an active market to be maintained, defaulted securities may be
          less actively traded than other securities and it may be difficult to
          dispose of substantial holdings of such securities at prevailing
          market prices. The Portfolios will limit holdings of any such
          securities to amounts that the portfolio managers believe could be
          readily sold, and holdings of such securities would, in any event, be
          limited so as not to limit the Portfolios' ability to readily dispose
          of securities to meet redemptions.

          OTHER. Defaulted securities require active monitoring and may, at
          times, require participation in bankruptcy or receivership proceedings
          on behalf of the Portfolios.

Futures, Options and Other Derivative Instruments

          FUTURES CONTRACTS. The Portfolios may enter into contracts for the
          purchase or sale for future delivery of fixed-income securities,
          foreign currencies or contracts based on financial indices, including
          indices of U.S. government securities, foreign government securities,
          equity or fixed-income securities. U.S. futures contracts are traded
          on exchanges which have been designated "contract markets" by the CFTC
          and must be executed through a futures commission merchant ("FCM"), or
          brokerage firm, which is a member of the relevant contract market.
          Through their clearing corporations, the exchanges guarantee
          performance of the contracts as between the clearing members of the
          exchange.

          The buyer or seller of a futures contract is not required to deliver
          or pay for the underlying instrument unless the contract is held until
          the delivery date. However, both the buyer and seller are required to
          deposit "initial margin" for the benefit of the FCM when the contract
          is entered into. Initial margin deposits are equal to a percentage of
          the contract's value, as set by the exchange on which the contract is
          traded, and may be maintained in cash or certain other liquid assets
          by the Portfolios' custodian or subcustodian for the benefit of the
          FCM. Initial margin payments are similar to good faith deposits or
          performance bonds. Unlike margin extended by a securities broker,
          initial margin payments do not constitute purchasing securities on
          margin for purposes of the Portfolio's investment limitations. If the
          value of either party's position declines, that party will be required
          to make additional "variation margin" payments for the benefit of the
          FCM to settle the change in value on a daily basis. The party that has
          a gain may be entitled to receive all or a portion of this amount. In
          the event of the bankruptcy of the FCM that holds margin on behalf of
          a Portfolio, that Portfolio may be entitled to return of margin owed
          to such Portfolio only in proportion to the amount received by the
          FCM's other customers. Janus Capital will attempt to minimize the risk
          by careful monitoring of the creditworthiness of the FCMs with which
          the Portfolios do business and by depositing margin payments in a
          segregated account with the Portfolios' custodian.

                                                                              11
<PAGE>

          The Portfolios intend to comply with guidelines of eligibility for
          exclusion from the definition of the term "commodity pool operator"
          adopted by the CFTC and the National Futures Association, which
          regulate trading in the futures markets. The Portfolios will use
          futures contracts and related options primarily for bona fide hedging
          purposes within the meaning of CFTC regulations. To the extent that
          the Portfolios hold positions in futures contracts and related options
          that do not fall within the definition of bona fide hedging
          transactions, the aggregate initial margin and premiums required to
          establish such positions will not exceed 5% of the fair market value
          of a Portfolio's net assets, after taking into account unrealized
          profits and unrealized losses on any such contracts it has entered
          into.

          Although a Portfolio will segregate cash and liquid assets in an
          amount sufficient to cover its open futures obligations, the
          segregated assets would be available to that Portfolio immediately
          upon closing out the futures position, while settlement of securities
          transactions could take several days. However, because a Portfolio's
          cash that may otherwise be invested would be held uninvested or
          invested in other liquid assets so long as the futures position
          remains open, such Portfolio's return could be diminished due to the
          opportunity losses of foregoing other potential investments.

          A Portfolio's primary purpose in entering into futures contracts is to
          protect that Portfolio from fluctuations in the value of securities or
          interest rates without actually buying or selling the underlying debt
          or equity security. For example, if the Portfolio anticipates an
          increase in the price of stocks, and it intends to purchase stocks at
          a later time, that Portfolio could enter into a futures contract to
          purchase a stock index as a temporary substitute for stock purchases.
          If an increase in the market occurs that influences the stock index as
          anticipated, the value of the futures contracts will increase, thereby
          serving as a hedge against that Portfolio not participating in a
          market advance. This technique is sometimes known as an anticipatory
          hedge. To the extent a Portfolio enters into futures contracts for
          this purpose, the segregated assets maintained to cover such
          Portfolio's obligations with respect to the futures contracts will
          consist of liquid assets from its portfolio in an amount equal to the
          difference between the contract price and the aggregate value of the
          initial and variation margin payments made by that Portfolio with
          respect to the futures contracts. Conversely, if a Portfolio holds
          stocks and seeks to protect itself from a decrease in stock prices,
          the Portfolio might sell stock index futures contracts, thereby hoping
          to offset the potential decline in the value of its portfolio
          securities by a corresponding increase in the value of the futures
          contract position. A Portfolio could protect against a decline in
          stock prices by selling portfolio securities and investing in money
          market instruments, but the use of futures contracts enables it to
          maintain a defensive position without having to sell portfolio
          securities.


          If a Portfolio owns bonds and the portfolio manager expects interest
          rates to increase, that Portfolio may take a short position in
          interest rate futures contracts. Taking such a position would have
          much the same effect as that Portfolio selling bonds in its portfolio.
          If interest rates increase as anticipated, the value of the bonds
          would decline, but the value of that Portfolio's interest rate futures
          contract will increase, thereby keeping the net asset value of that
          Portfolio from declining as much as it may have otherwise. If, on the
          other hand, a portfolio manager expects interest rates to decline,
          that Portfolio may take a long position in interest rate futures
          contracts in anticipation of later closing out the futures position
          and purchasing the bonds. Although a Portfolio can accomplish similar
          results by buying securities with long maturities and selling
          securities with short maturities, given the greater liquidity of the
          futures market than the cash market, it may be possible to accomplish
          the same result more easily and more quickly by using futures
          contracts as an investment tool to reduce risk.


          The ordinary spreads between prices in the cash and futures markets,
          due to differences in the nature of those markets, are subject to
          distortions. First, all participants in the futures market are subject
          to initial margin and variation margin requirements. Rather than
          meeting additional variation margin requirements,

 12
<PAGE>

          investors may close out futures contracts through offsetting
          transactions which could distort the normal price relationship between
          the cash and futures markets. Second, the liquidity of the futures
          market depends on participants entering into offsetting transactions
          rather than making or taking delivery of the instrument underlying a
          futures contract. To the extent participants decide to make or take
          delivery, liquidity in the futures market could be reduced and prices
          in the futures market distorted. Third, from the point of view of
          speculators, the margin deposit requirements in the futures market are
          less onerous than margin requirements in the securities market.
          Therefore, increased participation by speculators in the futures
          market may cause temporary price distortions. Due to the possibility
          of the foregoing distortions, a correct forecast of general price
          trends by a portfolio manager still may not result in a successful use
          of futures.

          Futures contracts entail risks. Although the Portfolios believe that
          use of such contracts will benefit the Portfolios, a Portfolio's
          overall performance could be worse than if such Portfolio had not
          entered into futures contracts if the portfolio manager's investment
          judgement proves incorrect. For example, if a Portfolio has hedged
          against the effects of a possible decrease in prices of securities
          held in its portfolio and prices increase instead, that Portfolio will
          lose part or all of the benefit of the increased value of these
          securities because of offsetting losses in its futures positions. In
          addition, if a Portfolio has insufficient cash, it may have to sell
          securities from its portfolio to meet daily variation margin
          requirements. Those sales may be, but will not necessarily be, at
          increased prices which reflect the rising market and may occur at a
          time when the sales are disadvantageous to such Portfolio.

          The prices of futures contracts depend primarily on the value of their
          underlying instruments. Because there are a limited number of types of
          futures contracts, it is possible that the standardized futures
          contracts available to a Portfolio will not match exactly such
          Portfolio's current or potential investments. A Portfolio may buy and
          sell futures contracts based on underlying instruments with different
          characteristics from the securities in which it typically
          invests - for example, by hedging investments in portfolio securities
          with a futures contract based on a broad index of securities - which
          involves a risk that the futures position will not correlate precisely
          with the performance of such Portfolio's investments.

          Futures prices can also diverge from the prices of their underlying
          instruments, even if the underlying instruments closely correlate with
          a Portfolio's investments. Futures prices are affected by factors such
          as current and anticipated short-term interest rates, changes in
          volatility of the underlying instruments and the time remaining until
          expiration of the contract. Those factors may affect securities prices
          differently from futures prices. Imperfect correlations between a
          Portfolio's investments and its futures positions also may result from
          differing levels of demand in the futures markets and the securities
          markets, from structural differences in how futures and securities are
          traded, and from imposition of daily price fluctuation limits for
          futures contracts. A Portfolio may buy or sell futures contracts with
          a greater or lesser value than the securities it wishes to hedge or is
          considering purchasing in order to attempt to compensate for
          differences in historical volatility between the futures contract and
          the securities, although this may not be successful in all cases. If
          price changes in a Portfolio's futures positions are poorly correlated
          with its other investments, its futures positions may fail to produce
          desired gains or result in losses that are not offset by the gains in
          that Portfolio's other investments.

          Because futures contracts are generally settled within a day from the
          date they are closed out, compared with a settlement period of three
          days for some types of securities, the futures markets can provide
          superior liquidity to the securities markets. Nevertheless, there is
          no assurance that a liquid secondary market will exist for any
          particular futures contract at any particular time. In addition,
          futures exchanges may establish daily price fluctuation limits for
          futures contracts and may halt trading if a contract's price

                                                                              13
<PAGE>

          moves upward or downward more than the limit in a given day. On
          volatile trading days when the price fluctuation limit is reached, it
          may be impossible for a Portfolio to enter into new positions or close
          out existing positions. If the secondary market for a futures contract
          is not liquid because of price fluctuation limits or otherwise, a
          Portfolio may not be able to promptly liquidate unfavorable futures
          positions and potentially could be required to continue to hold a
          futures position until the delivery date, regardless of changes in its
          value. As a result, such Portfolio's access to other assets held to
          cover its futures positions also could be impaired.

          OPTIONS ON FUTURES CONTRACTS. The Portfolios may buy and write put and
          call options on futures contracts. An option on a future gives a
          Portfolio the right (but not the obligation) to buy or sell a futures
          contract at a specified price on or before a specified date. The
          purchase of a call option on a futures contract is similar in some
          respects to the purchase of a call option on an individual security.
          Depending on the pricing of the option compared to either the price of
          the futures contract upon which it is based or the price of the
          underlying instrument, ownership of the option may or may not be less
          risky than ownership of the futures contract or the underlying
          instrument. As with the purchase of futures contracts, when a
          Portfolio is not fully invested it may buy a call option on a futures
          contract to hedge against a market advance.

          The writing of a call option on a futures contract constitutes a
          partial hedge against declining prices of the security or foreign
          currency which is deliverable under, or of the index comprising, the
          futures contract. If the futures price at the expiration of the option
          is below the exercise price, a Portfolio will retain the full amount
          of the option premium which provides a partial hedge against any
          decline that may have occurred in that Portfolio's holdings. The
          writing of a put option on a futures contract constitutes a partial
          hedge against increasing prices of the security or foreign currency
          which is deliverable under, or of the index comprising, the futures
          contract. If the futures price at expiration of the option is higher
          than the exercise price, a Portfolio will retain the full amount of
          the option premium which provides a partial hedge against any increase
          in the price of securities which that Portfolio is considering buying.
          If a call or put option a Portfolio has written is exercised, such
          Portfolio will incur a loss which will be reduced by the amount of the
          premium it received. Depending on the degree of correlation between
          the change in the value of its portfolio securities and changes in the
          value of the futures positions, a Portfolio's losses from existing
          options on futures may to some extent be reduced or increased by
          changes in the value of portfolio securities.

          The purchase of a put option on a futures contract is similar in some
          respects to the purchase of protective put options on portfolio
          securities. For example, a Portfolio may buy a put option on a futures
          contract to hedge its portfolio against the risk of falling prices or
          rising interest rates.

          The amount of risk a Portfolio assumes when it buys an option on a
          futures contract is the premium paid for the option plus related
          transaction costs. In addition to the correlation risks discussed
          above, the purchase of an option also entails the risk that changes in
          the value of the underlying futures contract will not be fully
          reflected in the value of the options bought.

          FORWARD CONTRACTS. A forward contract is an agreement between two
          parties in which one party is obligated to deliver a stated amount of
          a stated asset at a specified time in the future and the other party
          is obligated to pay a specified amount for the assets at the time of
          delivery. The Portfolios may enter into forward contracts to purchase
          and sell government securities, equity or income securities, foreign
          currencies or other financial instruments. Forward contracts generally
          are traded in an interbank market conducted directly between traders
          (usually large commercial banks) and their customers. Unlike futures
          contracts, which are standardized contracts, forward contracts can be
          specifically drawn to meet the needs

 14
<PAGE>

          of the parties that enter into them. The parties to a forward contract
          may agree to offset or terminate the contract before its maturity, or
          may hold the contract to maturity and complete the contemplated
          exchange.

          The following discussion summarizes the Portfolios' principal uses of
          forward foreign currency exchange contracts ("forward currency
          contracts"). A Portfolio may enter into forward currency contracts
          with stated contract values of up to the value of that Portfolio's
          assets. A forward currency contract is an obligation to buy or sell an
          amount of a specified currency for an agreed price (which may be in
          U.S. dollars or a foreign currency). A Portfolio will exchange foreign
          currencies for U.S. dollars and for other foreign currencies in the
          normal course of business and may buy and sell currencies through
          forward currency contracts in order to fix a price for securities it
          has agreed to buy or sell ("transaction hedge"). A Portfolio also may
          hedge some or all of its investments denominated in a foreign currency
          or exposed to foreign currency fluctuations against a decline in the
          value of that currency relative to the U.S. dollar by entering into
          forward currency contracts to sell an amount of that currency (or a
          proxy currency whose performance is expected to replicate or exceed
          the performance of that currency relative to the U.S. dollar)
          approximating the value of some or all of its portfolio securities
          denominated in that currency ("position hedge") or by participating in
          options or futures contracts with respect to the currency. A Portfolio
          also may enter into a forward currency contract with respect to a
          currency where the Portfolio is considering the purchase or sale of
          investments denominated in that currency but has not yet selected the
          specific investments ("anticipatory hedge"). In any of these
          circumstances a Portfolio may, alternatively, enter into a forward
          currency contract to purchase or sell one foreign currency for a
          second currency that is expected to perform more favorably relative to
          the U.S. dollar if the portfolio manager believes there is a
          reasonable degree of correlation between movements in the two
          currencies ("cross-hedge").

          These types of hedging minimize the effect of currency appreciation as
          well as depreciation, but do not eliminate fluctuations in the
          underlying U.S. dollar equivalent value of the proceeds of or rates of
          return on a Portfolio's foreign currency denominated portfolio
          securities. The matching of the increase in value of a forward
          contract and the decline in the U.S. dollar equivalent value of the
          foreign currency denominated asset that is the subject of the hedge
          generally will not be precise. Shifting a Portfolio's currency
          exposure from one foreign currency to another removes that Portfolio's
          opportunity to profit from increases in the value of the original
          currency and involves a risk of increased losses to such Portfolio if
          its portfolio manager's projection of future exchange rates is
          inaccurate. Proxy hedges and cross-hedges may result in losses if the
          currency used to hedge does not perform similarly to the currency in
          which hedged securities are denominated. Unforeseen changes in
          currency prices may result in poorer overall performance for a
          Portfolio than if it had not entered into such contracts.

          The Portfolios will cover outstanding forward currency contracts by
          maintaining liquid portfolio securities denominated in or whose value
          is tied to the currency underlying the forward contract or the
          currency being hedged. To the extent that a Portfolio is not able to
          cover its forward currency positions with underlying portfolio
          securities, the Portfolios' custodian will segregate cash or other
          liquid assets having a value equal to the aggregate amount of such
          Portfolio's commitments under forward contracts entered into with
          respect to position hedges, cross-hedges and anticipatory hedges. If
          the value of the securities used to cover a position or the value of
          segregated assets declines, a Portfolio will find alternative cover or
          segregate additional cash or other liquid assets on a daily basis so
          that the value of the covered and segregated assets will be equal to
          the amount of such Portfolio's commitments with respect to such
          contracts. As an alternative to segregating assets, a Portfolio may
          buy call options permitting such Portfolio

                                                                              15

          to buy the amount of foreign currency being hedged by a forward sale
          contract or a Portfolio may buy put options permitting it to sell the
          amount of foreign currency subject to a forward buy contract.

          While forward contracts are not currently regulated by the CFTC, the
          CFTC may in the future assert authority to regulate forward contracts.
          In such event, the Portfolios' ability to utilize forward contracts
          may be restricted. In addition, a Portfolio may not always be able to
          enter into forward contracts at attractive prices and may be limited
          in its ability to use these contracts to hedge Portfolio assets.

          OPTIONS ON FOREIGN CURRENCIES. The Portfolios may buy and write
          options on foreign currencies in a manner similar to that in which
          futures or forward contracts on foreign currencies will be utilized.
          For example, a decline in the U.S. dollar value of a foreign currency
          in which portfolio securities are denominated will reduce the U.S.
          dollar value of such securities, even if their value in the foreign
          currency remains constant. In order to protect against such
          diminutions in the value of portfolio securities, a Portfolio may buy
          put options on the foreign currency. If the value of the currency
          declines, such Portfolio will have the right to sell such currency for
          a fixed amount in U.S. dollars, thereby offsetting, in whole or in
          part, the adverse effect on its portfolio.

          Conversely, when a rise in the U.S. dollar value of a currency in
          which securities to be acquired are denominated is projected, thereby
          increasing the cost of such securities, a Portfolio may buy call
          options on the foreign currency. The purchase of such options could
          offset, at least partially, the effects of the adverse movements in
          exchange rates. As in the case of other types of options, however, the
          benefit to a Portfolio from purchases of foreign currency options will
          be reduced by the amount of the premium and related transaction costs.
          In addition, if currency exchange rates do not move in the direction
          or to the extent projected, a Portfolio could sustain losses on
          transactions in foreign currency options that would require such
          Portfolio to forego a portion or all of the benefits of advantageous
          changes in those rates.

          The Portfolios may also write options on foreign currencies. For
          example, to hedge against a potential decline in the U.S. dollar value
          of foreign currency denominated securities due to adverse fluctuations
          in exchange rates, a Portfolio could, instead of purchasing a put
          option, write a call option on the relevant currency. If the expected
          decline occurs, the option will most likely not be exercised and the
          decline in value of portfolio securities will be offset by the amount
          of the premium received.

          Similarly, instead of purchasing a call option to hedge against a
          potential increase in the U.S. dollar cost of securities to be
          acquired, a Portfolio could write a put option on the relevant
          currency which, if rates move in the manner projected, should expire
          unexercised and allow that Portfolio to hedge the increased cost up to
          the amount of the premium. As in the case of other types of options,
          however, the writing of a foreign currency option will constitute only
          a partial hedge up to the amount of the premium. If exchange rates do
          not move in the expected direction, the option may be exercised and a
          Portfolio would be required to buy or sell the underlying currency at
          a loss which may not be offset by the amount of the premium. Through
          the writing of options on foreign currencies, a Portfolio also may
          lose all or a portion of the benefits which might otherwise have been
          obtained from favorable movements in exchange rates.

          The Portfolios may write covered call options on foreign currencies. A
          call option written on a foreign currency by a Portfolio is "covered"
          if that Portfolio owns the foreign currency underlying the call or has
          an absolute and immediate right to acquire that foreign currency
          without additional cash consideration (or for additional cash
          consideration held in a segregated account by its custodian) upon
          conversion or exchange of other foreign currencies held in its
          portfolio. A call option is also covered if a Portfolio has a call on
          the same foreign currency in the same principal amount as the call
          written if the exercise price of the call held (i) is equal to or less
          than the exercise price of the call written or (ii) is greater than
          the

 16
<PAGE>

          exercise price of the call written, if the difference is maintained by
          such Portfolio in cash or other liquid assets in a segregated account
          with the Portfolios' custodian.

          The Portfolios also may write call options on foreign currencies for
          cross-hedging purposes. A call option on a foreign currency is for
          cross-hedging purposes if it is designed to provide a hedge against a
          decline due to an adverse change in the exchange rate in the U.S.
          dollar value of a security which a Portfolio owns or has the right to
          acquire and which is denominated in the currency underlying the
          option. Call options on foreign currencies which are entered into for
          cross-hedging purposes are not covered. However, in such
          circumstances, a Portfolio will collateralize the option by
          segregating cash or other liquid assets in an amount not less than the
          value of the underlying foreign currency in U.S. dollars
          marked-to-market daily.

          OPTIONS ON SECURITIES. In an effort to increase current income and to
          reduce fluctuations in net asset value, the Portfolios may write
          covered put and call options and buy put and call options on
          securities that are traded on United States and foreign securities
          exchanges and over-the-counter. The Portfolios may write and buy
          options on the same types of securities that the Portfolios may
          purchase directly.

          A put option written by a Portfolio is "covered" if that Portfolio (i)
          segregates cash not available for investment or other liquid assets
          with a value equal to the exercise price of the put with the
          Portfolios' custodian or (ii) holds a put on the same security and in
          the same principal amount as the put written and the exercise price of
          the put held is equal to or greater than the exercise price of the put
          written. The premium paid by the buyer of an option will reflect,
          among other things, the relationship of the exercise price to the
          market price and the volatility of the underlying security, the
          remaining term of the option, supply and demand and interest rates.

          A call option written by a Portfolio is "covered" if that Portfolio
          owns the underlying security covered by the call or has an absolute
          and immediate right to acquire that security without additional cash
          consideration (or for additional cash consideration held in a
          segregated account by the Portfolios' custodian) upon conversion or
          exchange of other securities held in its portfolio. A call option is
          also deemed to be covered if a Portfolio holds a call on the same
          security and in the same principal amount as the call written and the
          exercise price of the call held (i) is equal to or less than the
          exercise price of the call written or (ii) is greater than the
          exercise price of the call written if the difference is maintained by
          that Portfolio in cash and other liquid assets in a segregated account
          with its custodian.

          The Portfolios also may write call options that are not covered for
          cross-hedging purposes. A Portfolio collateralizes its obligation
          under a written call option for cross-hedging purposes by segregating
          cash or other liquid assets in an amount not less than the market
          value of the underlying security, marked-to-market daily. A Portfolio
          would write a call option for cross-hedging purposes, instead of
          writing a covered call option, when the premium to be received from
          the cross-hedge transaction would exceed that which would be received
          from writing a covered call option and its portfolio manager believes
          that writing the option would achieve the desired hedge.

          The writer of an option may have no control over when the underlying
          securities must be sold, in the case of a call option, or bought, in
          the case of a put option, since with regard to certain options, the
          writer may be assigned an exercise notice at any time prior to the
          termination of the obligation. Whether or not an option expires
          unexercised, the writer retains the amount of the premium. This
          amount, of course, may, in the case of a covered call option, be
          offset by a decline in the market value of the underlying security
          during the option period. If a call option is exercised, the writer
          experiences a profit or loss from the sale of the underlying security.
          If a put option is exercised, the writer must fulfill the obligation
          to buy the

                                                                              17
<PAGE>

          underlying security at the exercise price, which will usually exceed
          the then market value of the underlying security.

          The writer of an option that wishes to terminate its obligation may
          effect a "closing purchase transaction." This is accomplished by
          buying an option of the same series as the option previously written.
          The effect of the purchase is that the writer's position will be
          canceled by the clearing corporation. However, a writer may not effect
          a closing purchase transaction after being notified of the exercise of
          an option. Likewise, an investor who is the holder of an option may
          liquidate its position by effecting a "closing sale transaction." This
          is accomplished by selling an option of the same series as the option
          previously bought. There is no guarantee that either a closing
          purchase or a closing sale transaction can be effected.

          In the case of a written call option, effecting a closing transaction
          will permit a Portfolio to write another call option on the underlying
          security with either a different exercise price or expiration date or
          both. In the case of a written put option, such transaction will
          permit a Portfolio to write another put option to the extent that the
          exercise price is secured by deposited liquid assets. Effecting a
          closing transaction also will permit a Portfolio to use the cash or
          proceeds from the concurrent sale of any securities subject to the
          option for other investments. If a Portfolio desires to sell a
          particular security from its portfolio on which it has written a call
          option, such Portfolio will effect a closing transaction prior to or
          concurrent with the sale of the security.

          A Portfolio will realize a profit from a closing transaction if the
          price of the purchase transaction is less than the premium received
          from writing the option or the price received from a sale transaction
          is more than the premium paid to buy the option. A Portfolio will
          realize a loss from a closing transaction if the price of the purchase
          transaction is more than the premium received from writing the option
          or the price received from a sale transaction is less than the premium
          paid to buy the option. Because increases in the market of a call
          option generally will reflect increases in the market price of the
          underlying security, any loss resulting from the repurchase of a call
          option is likely to be offset in whole or in part by appreciation of
          the underlying security owned by a Portfolio.

          An option position may be closed out only where a secondary market for
          an option of the same series exists. If a secondary market does not
          exist, the Portfolio may not be able to effect closing transactions in
          particular options and the Portfolio would have to exercise the
          options in order to realize any profit. If a Portfolio is unable to
          effect a closing purchase transaction in a secondary market, it will
          not be able to sell the underlying security until the option expires
          or it delivers the underlying security upon exercise. The absence of a
          liquid secondary market may be due to the following: (i) insufficient
          trading interest in certain options, (ii) restrictions imposed by a
          national securities exchange ("Exchange") on which the option is
          traded on opening or closing transactions or both, (iii) trading
          halts, suspensions or other restrictions imposed with respect to
          particular classes or series of options or underlying securities, (iv)
          unusual or unforeseen circumstances that interrupt normal operations
          on an Exchange, (v) the facilities of an Exchange or of the Options
          Clearing Corporation ("OCC") may not at all times be adequate to
          handle current trading volume, or (vi) one or more Exchanges could,
          for economic or other reasons, decide or be compelled at some future
          date to discontinue the trading of options (or a particular class or
          series of options), in which event the secondary market on that
          Exchange (or in that class or series of options) would cease to exist,
          although outstanding options on that Exchange that had been issued by
          the OCC as a result of trades on that Exchange would continue to be
          exercisable in accordance with their terms.

          A Portfolio may write options in connection with buy-and-write
          transactions. In other words, a Portfolio may buy a security and then
          write a call option against that security. The exercise price of such
          call will

 18
<PAGE>

          depend upon the expected price movement of the underlying security.
          The exercise price of a call option may be below ("in-the-money"),
          equal to ("at-the-money") or above ("out-of-the-money") the current
          value of the underlying security at the time the option is written.
          Buy-and-write transactions using in-the-money call options may be used
          when it is expected that the price of the underlying security will
          remain flat or decline moderately during the option period.
          Buy-and-write transactions using at-the-money call options may be used
          when it is expected that the price of the underlying security will
          remain fixed or advance moderately during the option period.
          Buy-and-write transactions using out-of-the-money call options may be
          used when it is expected that the premiums received from writing the
          call option plus the appreciation in the market price of the
          underlying security up to the exercise price will be greater than the
          appreciation in the price of the underlying security alone. If the
          call options are exercised in such transactions, a Portfolio's maximum
          gain will be the premium received by it for writing the option,
          adjusted upwards or downwards by the difference between that
          Portfolio's purchase price of the security and the exercise price. If
          the options are not exercised and the price of the underlying security
          declines, the amount of such decline will be offset by the amount of
          premium received.

          The writing of covered put options is similar in terms of risk and
          return characteristics to buy-and-write transactions. If the market
          price of the underlying security rises or otherwise is above the
          exercise price, the put option will expire worthless and a Portfolio's
          gain will be limited to the premium received. If the market price of
          the underlying security declines or otherwise is below the exercise
          price, a Portfolio may elect to close the position or take delivery of
          the security at the exercise price and that Portfolio's return will be
          the premium received from the put options minus the amount by which
          the market price of the security is below the exercise price.

          A Portfolio may buy put options to hedge against a decline in the
          value of its portfolio. By using put options in this way, a Portfolio
          will reduce any profit it might otherwise have realized in the
          underlying security by the amount of the premium paid for the put
          option and by transaction costs.

          A Portfolio may buy call options to hedge against an increase in the
          price of securities that it may buy in the future. The premium paid
          for the call option plus any transaction costs will reduce the
          benefit, if any, realized by such Portfolio upon exercise of the
          option, and, unless the price of the underlying security rises
          sufficiently, the option may expire worthless to that Portfolio.

          EURODOLLAR INSTRUMENTS. A Portfolio may make investments in Eurodollar
          instruments. Eurodollar instruments are U.S. dollar-denominated
          futures contracts or options thereon which are linked to the London
          Interbank Offered Rate ("LIBOR"), although foreign
          currency-denominated instruments are available from time to time.
          Eurodollar futures contracts enable purchasers to obtain a fixed rate
          for the lending of funds and sellers to obtain a fixed rate for
          borrowings. A Portfolio might use Eurodollar futures contracts and
          options thereon to hedge against changes in LIBOR, to which many
          interest rate swaps and fixed-income instruments are linked.

          SWAPS AND SWAP-RELATED PRODUCTS. A Portfolio may enter into interest
          rate swaps, caps and floors on either an asset-based or
          liability-based basis, depending upon whether it is hedging its assets
          or its liabilities, and will usually enter into interest rate swaps on
          a net basis (i.e., the two payment streams are netted out, with a
          Portfolio receiving or paying, as the case may be, only the net amount
          of the two payments). The net amount of the excess, if any, of a
          Portfolio's obligations over its entitlement with respect to each
          interest rate swap will be calculated on a daily basis and an amount
          of cash or other liquid assets having an aggregate net asset value at
          least equal to the accrued excess will be maintained in a segregated
          account by the Portfolios' custodian. If a Portfolio enters into an
          interest rate swap on other

                                                                              19
<PAGE>

          than a net basis, it would maintain a segregated account in the full
          amount accrued on a daily basis of its obligations with respect to the
          swap. A Portfolio will not enter into any interest rate swap, cap or
          floor transaction unless the unsecured senior debt or the
          claims-paying ability of the other party thereto is rated in one of
          the three highest rating categories of at least one NRSRO at the time
          of entering into such transaction. Janus Capital will monitor the
          creditworthiness of all counterparties on an ongoing basis. If there
          is a default by the other party to such a transaction, a Portfolio
          will have contractual remedies pursuant to the agreements related to
          the transaction.

          The swap market has grown substantially in recent years with a large
          number of banks and investment banking firms acting both as principals
          and as agents utilizing standardized swap documentation. Janus Capital
          has determined that, as a result, the swap market has become
          relatively liquid. Caps and floors are more recent innovations for
          which standardized documentation has not yet been developed and,
          accordingly, they are less liquid than swaps. To the extent a
          Portfolio sells (i.e., writes) caps and floors, it will segregate cash
          or other liquid assets having an aggregate net asset value at least
          equal to the full amount, accrued on a daily basis, of its obligations
          with respect to any caps or floors.

          There is no limit on the amount of interest rate swap transactions
          that may be entered into by a Portfolio. These transactions may in
          some instances involve the delivery of securities or other underlying
          assets by a Portfolio or its counterparty to collateralize obligations
          under the swap. Under the documentation currently used in those
          markets, the risk of loss with respect to interest rate swaps is
          limited to the net amount of the payments that a Portfolio is
          contractually obligated to make. If the other party to an interest
          rate swap that is not collateralized defaults, a Portfolio would risk
          the loss of the net amount of the payments that it contractually is
          entitled to receive. A Portfolio may buy and sell (i.e., write) caps
          and floors without limitation, subject to the segregation requirement
          described above.

          ADDITIONAL RISKS OF OPTIONS ON FOREIGN CURRENCIES, FORWARD CONTRACTS
          AND FOREIGN INSTRUMENTS. Unlike transactions entered into by the
          Portfolios in futures contracts, options on foreign currencies and
          forward contracts are not traded on contract markets regulated by the
          CFTC or (with the exception of certain foreign currency options) by
          the SEC. To the contrary, such instruments are traded through
          financial institutions acting as market-makers, although foreign
          currency options are also traded on certain Exchanges, such as the
          Philadelphia Stock Exchange and the Chicago Board Options Exchange,
          subject to SEC regulation. Similarly, options on currencies may be
          traded over-the-counter. In an over-the-counter trading environment,
          many of the protections afforded to Exchange participants will not be
          available. For example, there are no daily price fluctuation limits,
          and adverse market movements could therefore continue to an unlimited
          extent over a period of time. Although the buyer of an option cannot
          lose more than the amount of the premium plus related transaction
          costs, this entire amount could be lost. Moreover, an option writer
          and a buyer or seller of futures or forward contracts could lose
          amounts substantially in excess of any premium received or initial
          margin or collateral posted due to the potential additional margin and
          collateral requirements associated with such positions.

          Options on foreign currencies traded on Exchanges are within the
          jurisdiction of the SEC, as are other securities traded on Exchanges.
          As a result, many of the protections provided to traders on organized
          Exchanges will be available with respect to such transactions. In
          particular, all foreign currency option positions entered into on an
          Exchange are cleared and guaranteed by the OCC, thereby reducing the
          risk of counterparty default. Further, a liquid secondary market in
          options traded on an Exchange may be more readily available than in
          the over-the-counter market, potentially permitting a Portfolio to
          liquidate open positions at a profit prior to exercise or expiration,
          or to limit losses in the event of adverse market movements.

          The purchase and sale of exchange-traded foreign currency options,
          however, is subject to the risks of the availability of a liquid
          secondary market described above, as well as the risks regarding
          adverse market movements, margining of options written, the nature of
          the foreign currency market, possible intervention by governmental
          authorities and the effects of other political and economic events. In
          addition, exchange-traded options on foreign currencies involve
          certain risks not presented by the over-the-counter market. For
          example, exercise and settlement of such options must be made
          exclusively through the OCC, which has established banking
          relationships in applicable foreign countries for this purpose. As a
          result, the OCC may, if it determines that foreign governmental
          restrictions or taxes would prevent the orderly settlement of foreign
          currency option exercises, or would result in undue burdens on the OCC
          or its clearing member, impose special procedures on exercise and
          settlement, such as technical changes in the mechanics of delivery of
          currency, the fixing of dollar settlement prices or prohibitions on
          exercise.

          In addition, options on U.S. government securities, futures contracts,
          options on futures contracts, forward contracts and options on foreign
          currencies may be traded on foreign exchanges and over-the-counter in
          foreign countries. Such transactions are subject to the risk of
          governmental actions affecting trading in or the prices of foreign
          currencies or securities. The value of such positions also could be
          adversely affected by (i) other complex foreign political and economic
          factors, (ii) lesser availability than in the United States of data on
          which to make trading decisions, (iii) delays in a Portfolio's ability
          to act upon economic events occurring in foreign markets during
          non-business hours in the United States, (iv) the imposition of
          different exercise and settlement terms and procedures and margin
          requirements than in the United States, and (v) low trading volume.

                                                                              21

Investment adviser

          As stated in the Prospectus, each Portfolio has an Investment Advisory
          Agreement with Janus Capital, 100 Fillmore Street, Denver, Colorado
          80206-4928. Each Advisory Agreement provides that Janus Capital will
          furnish continuous advice and recommendations concerning the
          Portfolios' investments, provide office space for the Portfolios, and
          pay the salaries, fees and expenses of all Portfolio officers and of
          those Trustees who are affiliated with Janus Capital. Janus Capital
          also may make payments to selected broker-dealer firms or institutions
          which were instrumental in the acquisition of shareholders for the
          Portfolios or other Janus Funds or which perform recordkeeping or
          other services with respect to shareholder accounts. The minimum
          aggregate size required for eligibility for such payments, and the
          factors in selecting the broker-dealer firms and institutions to which
          they will be made, are determined from time to time by Janus Capital.
          Janus Capital is also authorized to perform the management and
          administrative services necessary for the operation of the Portfolios.

          The Portfolios pay custodian and transfer agent fees and expenses,
          brokerage commissions and dealer spreads and other expenses in
          connection with the execution of portfolio transactions, legal and
          accounting expenses, interest and taxes, registration fees, expenses
          of shareholders' meetings and reports to shareholders, fees and
          expenses of Portfolio Trustees who are not affiliated with Janus
          Capital and other costs of complying with applicable laws regulating
          the sale of Portfolio shares. Pursuant to the Advisory Agreements,
          Janus Capital furnishes certain other services, including net asset
          value determination, portfolio accounting and recordkeeping, for which
          the Portfolios may reimburse Janus Capital for its costs.


          Growth Portfolio, Aggressive Growth Portfolio, Capital Appreciation
          Portfolio, Balanced Portfolio, Equity Income Portfolio, Growth and
          Income Portfolio, International Growth Portfolio, Worldwide Growth
          Portfolio, Global Life Sciences Portfolio and Global Technology
          Portfolio have each agreed to compensate Janus Capital for its
          services by the monthly payment of a fee at the annual rate of 0.65%
          of the average daily net assets of each Portfolio. This fee is the
          same or lower than the fee that each of the Equity Portfolios paid
          under its old agreement during its most recent fiscal year.



          Janus Capital has agreed to reimburse Equity Income Portfolio, Global
          Life Sciences Portfolio and Global Technology Portfolio by the amount,
          if any, that such Portfolio's normal operating expenses in any fiscal
          year, including the investment advisory fee but excluding the
          distribution fee described below, brokerage commissions, interest,
          taxes and extraordinary expenses, exceed an annual rate of 1.25% of
          the average daily net assets of the Portfolio until at least the next
          annual renewal of the advisory agreements. Mortality risk, expense
          risk and other charges imposed by participating insurance companies
          are also excluded from the above expense limitation.



          High-Yield Portfolio has agreed to compensate Janus Capital for its
          services by the monthly payment of a fee at the annual rate of .75% of
          the first $300 million of average daily net assets of the Portfolio
          and .65% of the average daily net assets in excess of $300 million.
          Flexible Income Portfolio has agreed to compensate Janus Capital for
          its services by the monthly payment of a fee at the annual rate of
          .65% of the first $300 million of the average daily net assets of the
          Portfolio, plus .55% of the average daily net assets of the Portfolio
          in excess of $300 million. Janus Capital has agreed to waive the
          advisory fee payable of High-Yield Portfolio and Flexible Income
          Portfolio in an amount equal to the amount, if any, that the
          Portfolio's normal operating expenses in any fiscal year, including
          the investment advisory fee but excluding the distribution fee
          described below, brokerage commissions, interest, taxes and
          extraordinary expenses, exceed 1% of the average daily net assets for
          a fiscal year. Mortality risk, expense risk and other charges imposed
          by participating insurance companies are also excluded from the above
          expense limitation. Janus Capital has agreed to continue such waivers
          until at least the next annual renewal of the advisory agreements.

          The following table summarizes the advisory fees paid by the
          Portfolios and any advisory fee waivers for the periods indicated. The
          information below is for fiscal years ended December 31. The
          information presented in the table below reflects the management fees
          in effect during each of the periods shown. Effective May 1, 2000, the
          Equity Portfolios' management fees were changed to 0.65% of the
          average daily net assets of each Portfolio. This fee is the same as or
          lower than the fee that each Equity Portfolio paid under its old
          agreement.

(1) In addition to these fee waivers, Janus Capital has agreed to reduce the
    advisory fee of the Growth, Aggressive Growth, Capital Appreciation,
    Balanced, Equity Income, Growth and Income, International Growth and
    Worldwide Growth Portfolios to the extent that such fee exceeds the
    effective rate of the Janus retail fund corresponding to such Portfolio.

(2) May 1, 1997 (inception) to December 31, 1997.
(3) Fee waiver by Janus Capital exceeded the advisory fee.

(4) May 1, 1998 (inception) to December 31, 1998.


(5) The Portfolio had not commenced operations as of December 31, 1999.



          The Advisory Agreement for each of the Portfolios is dated July 1,
          1997 (except Global Life Sciences Portfolio and Global Technology
          Portfolio, which are dated December 14, 1999). The Equity Portfolios'
          Advisory Agreements were each amended effective May 1, 2000 to
          decrease the management fees. Each Advisory Agreement will continue in
          effect until July 1, 2001, and thereafter from year to year so long as
          such continuance is approved annually by a majority of the Portfolios'
          Trustees who are not parties to the Advisory Agreements or interested
          persons of any such party, and by either a majority of the outstanding
          voting shares or the Trustees of the Portfolios. Each Advisory
          Agreement (i) may be terminated without the payment of any penalty by
          any Portfolio or Janus Capital on 60 days' written notice; (ii)
          terminates automatically in the event of its assignment; and (iii)
          generally, may not be amended without the approval by vote of a
          majority of the Trustees of the affected Portfolio, including the
          Trustees who are not interested persons of that Portfolio or Janus
          Capital and, to the extent required by the 1940 Act, the vote of a
          majority of the outstanding voting securities of that Portfolio.


          Janus Capital acts as sub-adviser for a number of private-label mutual
          funds and provides separate account advisor services for institutional
          accounts. Investment decisions for each account managed by Janus
          Capital, including the Portfolios, are made independently from those
          for any other account that is or may in the future become managed by
          Janus Capital or its affiliates. If, however, a number of accounts
          managed by Janus Capital are contemporaneously engaged in the purchase
          or sale of the same security, the orders may be aggregated and/or the
          transactions may be averaged as to price and allocated equitably to
          each account. In some cases, this policy might adversely affect the
          price paid or received by an account or



                                                                              23

          the size of the position obtained or liquidated for an account.
          Pursuant to an exemptive order granted by the SEC, the Portfolios and
          other portfolios advised by Janus Capital may also transfer daily
          uninvested cash balances into one or more joint trading accounts.
          Assets in the joint trading accounts are invested in money market
          instruments and the proceeds are allocated to the participating
          portfolios on a pro rata basis.


          Kansas City Southern Industries, Inc. ("KCSI"), indirectly through its
          wholly owned subsidiary, Stilwell Financial Inc., owns approximately
          81% of the outstanding voting stock of Janus Capital. KCSI is a
          publicly traded holding company whose primary subsidiaries are engaged
          in transportation, information processing and financial services.
          Thomas H. Bailey, President and Chairman of the Board of Janus
          Capital, owns approximately 12% of Janus Capital's voting stock and,
          by agreement with KCSI, selects at least a majority of Janus Capital's
          Board, subject to the approval of Stilwell Financial, which cannot be
          unreasonably withheld.



          KCSI has announced its intention to separate its transportation and
          financial services businesses. KCSI anticipates the separation to be
          completed in the first half of 2000.


          Each account managed by Janus Capital has its own investment objective
          and policies and is managed accordingly by a particular portfolio
          manager or team of portfolio managers. As a result, from time to time
          two or more different managed accounts may pursue divergent investment
          strategies with respect to investments or categories of investments.


          Janus Capital does not permit the Portfolios' portfolio managers to
          purchase and sell securities for their own accounts except under the
          limited exceptions contained in the Portfolios' Code of Ethics
          ("Code"). The Portfolios' Code of Ethics is on file with and available
          through the SEC Web site at www.sec.gov. The Code applies to
          Directors/Trustees of Janus Capital and the Portfolios, and employees
          of Janus Capital and the Trust, and requires investment personnel,
          inside Directors/Trustees of Janus Capital and the Portfolios and
          certain other designated employees deemed to have access to current
          trading information to pre-clear all transactions in securities not
          otherwise exempt under the Code. Requests for trading authorization
          will be denied when, among other reasons, the proposed personal
          transaction would be contrary to the provisions of the policy or would
          be deemed to adversely affect any transaction then known to be under
          consideration for or to have been effected on behalf of any client
          account, including the Portfolios.



          In addition to the pre-clearance requirement described above, the Code
          subjects such personnel to various trading restrictions and reporting
          obligations. All reportable transactions are required to be reviewed
          for compliance with the Code. Those persons also may be required under
          certain circumstances to forfeit their profits made from personal
          trading.



          The provisions of the Code are administered by and subject to
          exceptions authorized by Janus Capital.

Custodian, transfer agent and certain affiliations

          State Street Bank and Trust Company, P.O. Box 0351, Boston,
          Massachusetts 02117-0351 is the custodian of the domestic securities
          and cash of the Portfolios. State Street and the foreign subcustodians
          it selects, have custody of the assets of the Portfolios held outside
          the U.S. and cash incidental thereto. The custodians and subcustodians
          hold the Portfolios' assets in safekeeping and collect and remit the
          income thereon, subject to the instructions of each Portfolio.

          Janus Service Corporation, P.O. Box 173375, Denver, Colorado
          80217-3375, a wholly-owned subsidiary of Janus Capital, is the
          Portfolios' transfer agent. In addition, Janus Service provides
          certain other administrative, recordkeeping and shareholder relations
          services to the Portfolios. Janus Service Corporation is not
          compensated for its services related to the Shares, except for
          out-of-pocket costs.


          The Portfolios pay DST Systems, Inc., a subsidiary of KCSI, license
          fees at the annual rate of $3.06 per shareholder account for the
          equity portfolios and $3.98 per shareholder account for the
          fixed-income portfolios for the use of DST's shareholder accounting
          system. The Portfolios also pay DST $1.10 per closed shareholder
          account. The Portfolios pay DST for the use of its portfolio and fund
          accounting system a monthly base fee of $250 to $1,250 per month based
          on the number of Janus funds using the system and an asset charge of
          $1 per million dollars of net assets (not to exceed $500 per month).


          The Trustees have authorized the Portfolios to use another affiliate
          of DST as introducing broker for certain Portfolio transactions as a
          means to reduce Portfolio expenses through credits against the charges
          of DST and its affiliates with regard to commissions earned by such
          affiliate. DST charges shown above are net of such credits. See
          "Portfolio Transactions and Brokerage."

          Janus Distributors, Inc., 100 Fillmore Street, Denver, Colorado

          the Securities Exchange Act of 1934 and is a member of the National

Portfolio transactions and brokerage

          Decisions as to the assignment of portfolio business for the
          Portfolios and negotiation of its commission rates are made by Janus
          Capital whose policy is to obtain the "best execution" (prompt and
          reliable execution at the most favorable security price) of all
          portfolio transactions. The Portfolios may trade foreign securities in
          foreign countries because the best available market for these
          securities is often on foreign exchanges. In transactions on foreign
          stock exchanges, brokers' commissions are frequently fixed and are
          often higher than in the United States, where commissions are
          negotiated.

          In selecting brokers and dealers and in negotiating commissions, Janus
          Capital considers a number of factors, including but not limited to:
          Janus Capital's knowledge of currently available negotiated commission
          rates or prices of securities currently available and other current
          transaction costs; the nature of the security being traded; the size
          and type of the transaction; the nature and character of the markets
          for the security to be purchased or sold; the desired timing of the
          trade; the activity existing and expected in the market for the
          particular security; confidentiality; the quality of the execution,
          clearance and settlement services; financial stability of the broker
          or dealer; the existence of actual or apparent operational problems of
          any broker or dealer; rebates of commissions by a broker to a
          Portfolio or to a third party service provider to the Portfolio to pay
          Portfolio expenses; and research products or services provided. In
          recognition of the value of the foregoing factors, Janus Capital may
          place portfolio transactions with a broker or dealer with whom it has
          negotiated a commission that is in excess of the commission another
          broker or dealer would have charged for effecting that transaction if
          Janus Capital determines in good faith that such amount of commission
          was reasonable in relation to the value of the brokerage and research
          provided by such broker or dealer viewed in terms of either that
          particular transaction or of the overall responsibilities of Janus
          Capital. Research may include furnishing advice, either directly or
          through publications or writings, as to the value of securities, the
          advisability of purchasing or selling specific securities and the
          availability of securities or purchasers or sellers of securities;
          furnishing seminars, information, analyses and reports concerning
          issuers, industries, securities, trading markets and methods,
          legislative developments, changes in accounting practices, economic
          factors and trends and portfolio strategy; access to research
          analysts, corporate management personnel, industry experts, economists
          and government officials; comparative performance evaluation and
          technical measurement services and quotation services, and products
          and other services (such as third party publications, reports and
          analyses, and computer and electronic access, equipment, software,
          information and accessories that deliver, process or otherwise utilize
          information, including the research described above) that assist Janus
          Capital in carrying out its responsibilities. Research received from
          brokers or dealers is supplemental to Janus Capital's own research
          efforts. Most brokers and dealers used by Janus Capital provide
          research and other services described above.

          For the year ended December 31, 1999, the total brokerage commissions
          paid by the Portfolios to brokers and dealers in transactions
          identified for execution primarily on the basis of research and other
          services provided to the Portfolios are summarized below:

</TABLE>


Note: Portfolios that are not included in the table did not pay any commissions
      related to research for the stated period.

          Janus Capital may use research products and services in servicing
          other accounts in addition to the Portfolios. If Janus Capital
          determines that any research product or service has a mixed use, such
          that it also serves functions that do not assist in the investment
          decision-making process, Janus Capital may allocate the costs of such
          service or product accordingly. Only that portion of the product or
          service that Janus Capital determines will assist it in the investment
          decision-making process may be paid for in brokerage commission
          dollars. Such allocation may create a conflict of interest for Janus
          Capital.

          Janus Capital does not enter into agreements with any brokers
          regarding the placement of securities transactions because of the
          research services they provide. It does, however, have an internal
          procedure for allocating transactions in a manner consistent with its
          execution policy to brokers that it has identified as providing
          superior executions and research, research-related products or
          services which benefit its advisory clients, including the Portfolios.
          Research products and services incidental to effecting securities
          transactions furnished by brokers or dealers may be used in servicing
          any or all of Janus Capital's clients and such research may not
          necessarily be used by Janus Capital in connection with the accounts
          which paid commissions to the broker-dealer providing such research
          products and services.

          Janus Capital may consider sales of Portfolio Shares or shares of
          other Janus funds by a broker-dealer or the recommendation of a
          broker-dealer to its customers that they purchase Portfolio Shares as
          a factor in the selection of broker-dealers to execute Portfolio
          transactions. Janus Capital may also consider payments made by brokers
          effecting transactions for a Portfolio (i) to the Portfolio or (ii) to
          other persons on behalf of the Portfolio for services provided to the
          Portfolio for which it would be obligated to pay. In placing Portfolio
          business with such broker-dealers, Janus Capital will seek the best
          execution of each transaction.

          When the Portfolios purchase or sell a security in the
          over-the-counter market, the transaction takes place directly with a
          principal market-maker, without the use of a broker, except in those
          circumstances where in the opinion of Janus Capital better prices and
          executions will be achieved through the use of a broker.

          The Portfolios' Trustees have authorized Janus Capital to place
          transactions with DST Securities, Inc. ("DSTS"), a wholly-owned
          broker-dealer subsidiary of DST. Janus Capital may do so if it
          reasonably believes that the quality of the transaction and the
          associated commission are fair and reasonable and if, overall, the
          associated transaction costs, net of any credits described above under
          "Custodian, Transfer Agent and Certain Affiliations," are lower than
          those that would otherwise be incurred.

                                                                              27

Note: Portfolios that are not included in the table did not pay brokerage
      commissions because securities transactions for such Portfolios involved
      dealers acting as principals.


          Included in such brokerage commissions are the following amounts paid
          to DSTS, which served to reduce each Portfolio's out-of-pocket

  substantially the same.

Shares of the trust

NET ASSET VALUE DETERMINATION

          As stated in the Prospectus, the net asset value ("NAV") of the Shares
          of each Portfolio is determined once each day on which the NYSE is
          open, at the close of its regular trading session (normally 4:00 p.m.,
          New York time, Monday through Friday). The NAV of the Shares of each
          Portfolio is not determined on days the NYSE is closed (generally, New
          Year's Day, Martin Luther King Day, Presidents' Day, Good Friday,
          Memorial Day, Independence Day, Labor Day, Thanksgiving and
          Christmas). The per Share NAV of the Shares of each Portfolio is
          determined by dividing the total value of a Portfolio's securities and
          other assets, less liabilities, attributable to the Shares of a
          Portfolio, by the total number of Shares outstanding. In determining
          NAV, securities listed on an Exchange, the NASDAQ National Market and
          foreign markets are valued at the closing prices on such markets, or
          if such price is lacking for the trading period immediately preceding
          the time of determination, such securities are valued at their current
          bid price. Municipal securities held by the Portfolios are traded
          primarily in the over-the-counter market. Valuations of such
          securities are furnished by one or more pricing services employed by
          the Portfolios and are based upon last trade or closing sales prices
          or a computerized matrix system or appraisals obtained by a pricing
          service, in each case in reliance upon information concerning market
          transactions and quotations from recognized municipal securities
          dealers. Other securities that are traded on the over-the-counter
          market are valued at their closing bid prices. Foreign securities and
          currencies are converted to U.S. dollars using the exchange rate in
          effect at the close of the NYSE. Each Portfolio will determine the
          market value of individual securities held by it, by using prices
          provided by one or more professional pricing services which may
          provide market prices to other funds, or, as needed, by obtaining
          market quotations from independent broker-dealers. Short-term
          securities maturing within 60 days are valued on an amortized cost
          basis. Securities for which quotations are not readily available, and
          other assets, are valued at fair values determined in good faith under
          procedures established by and under the supervision of the Trustees.

          Trading in securities on European and Far Eastern securities exchanges
          and over-the-counter markets is normally completed well before the
          close of business on each business day in New York (i.e., a day on
          which the NYSE is open). In addition, European or Far Eastern
          securities trading generally or in a particular country or countries
          may not take place on all business days in New York. Furthermore,
          trading takes place in Japanese markets on certain Saturdays and in
          various foreign markets on days which are not business days in New
          York and on which a Portfolio's NAV is not calculated. A Portfolio
          calculates its NAV per Share, and therefore effects sales, redemptions
          and repurchases of its Shares, as of the close of the NYSE once on
          each day on which the NYSE is open. Such calculation may not take
          place contemporaneously with the determination of the prices of the
          foreign portfolio securities used in such calculation.

PURCHASES

          Shares of the Portfolios can be purchased only by (i) the separate
          accounts of participating insurance companies for the purpose of
          funding variable insurance contracts and (ii) qualified retirement
          plans. Participating insurance companies and certain designated
          organizations are authorized to receive purchase orders on the
          Portfolios' behalf and those organizations are authorized to designate
          their agents and affiliates as intermediaries to receive purchase
          orders. Purchase orders are deemed received by a Portfolio when
          authorized organizations, their agents or affiliates receive the
          order. The Portfolios are not responsible for the failure of any
          designated organization or its agents or affiliates to carry out its
          obligations to its customers. Shares of the Portfolios are purchased
          at the NAV per Share as determined at the close of the regular trading
          session of the NYSE next occurring after a purchase order is received
          and accepted by a Portfolio or its authorized agent. In order to
          receive a day's price, your order must be received by the close of the
          regular trading session of the NYSE as described above in "Net Asset
          Value Determination." The

                                                                              35

DISTRIBUTION AND SHAREHOLDER SERVICING PLAN

          Under a distribution and shareholder servicing plan ("Plan") adopted
          in accordance with Rule 12b-1 under the 1940 Act, the Shares may pay
          Janus Distributors, the Trust's distributor, a fee at an annual rate
          of up to 0.25% of the average daily net assets of the Shares of a
          Portfolio. Under the terms of the Plan, the Trust is authorized to
          make payments to Janus Distributors for remittance to insurance
          companies and qualified plan service providers as compensation for
          distribution and shareholder servicing performed by such service
          providers. The Plan is a compensation type plan and permits the
          payment at an annual rate of up to 0.25% of the average daily net
          assets of the Shares of a Portfolio for recordkeeping and
          administrative services as well as activities which are primarily
          intended to result in sales of the Shares, including but not limited
          to preparing, printing and distributing prospectuses, Statements of
          Additional Information, shareholder reports, and educational materials
          to prospective and existing contract owners and plan participants;
          responding to inquiries by contract owners and plan participants;
          receiving and answering correspondence; contract owner and participant
          level recordkeeping and administrative services; and similar
          activities. On December 14, 1999, Trustees unanimously approved the
          Plan which became effective on that date. The Plan and any Rule 12b-1
          related agreement that is entered into by the Portfolios or Janus
          Distributors in connection with the Plan will continue in effect for a
          period of more than one year only so long as continuance is
          specifically approved at least annually by a vote of a majority of the
          Trustees, and of a majority of the Trustees who are not interested
          persons (as defined in the 1940 Act) of the Trust and who have no
          direct or indirect financial interest in the operation of the Plan or
          any related agreements ("12b-1 Trustees"). All material amendments to
          the Plan must be approved by a majority vote of the Trustees,
          including a majority of the 12b-1 Trustees, at a meeting called for
          that purpose. In addition, the Plan may be terminated at any time,
          without penalty, by vote of a majority of the outstanding Shares of a
          Portfolio or by vote of a majority of 12b-1 Trustees.

REDEMPTIONS


          Redemptions, like purchases, may only be effected through the separate
          accounts of participating insurance companies or qualified retirement
          plans. Certain designated organizations are authorized to receive
          redemption orders on the Portfolios' behalf and those organizations
          are authorized to designate their agents and affiliates as
          intermediaries to receive redemption orders. Redemption orders are
          deemed received by a Portfolio when authorized organizations, their
          agents or affiliates receive the order. The Portfolios are not
          responsible for the failure of any designated organization or its
          agents or affiliates to carry out its obligations to its customers.
          Shares normally will be redeemed for cash, although each Portfolio
          retains the right to redeem some or all of its Shares in kind under
          unusual circumstances, in order to protect the interests of remaining
          shareholders, or to accommodate a request by a particular shareholder
          that does not adversely affect the interest of the remaining
          shareholders, by delivery of securities selected from its assets at
          its discretion. However, the Portfolios are governed by Rule 18f-1
          under the 1940 Act, which requires each Portfolio to redeem shares
          solely in cash up to the lesser of $250,000 or 1% of the NAV of that
          Portfolio during any 90-day period for any one shareholder. Should
          redemptions by any shareholder exceed such limitation, a Portfolio
          will have the option of redeeming the excess in cash or in kind. If
          shares are redeemed in kind, the redeeming shareholder might incur
          brokerage costs in converting the assets to cash. The method of
          valuing securities used to make redemptions in kind will be the same
          as the method of valuing portfolio securities described under "Shares
          of the Trust - Net Asset Value Determination" and such valuation will
          be made as of the same time the redemption price is determined.


 36
<PAGE>

          The right to require the Portfolios to redeem their shares may be
          suspended, or the date of payment may be postponed, whenever (1)
          trading on the NYSE is restricted, as determined by the SEC, or the
          NYSE is closed except for holidays and weekends, (2) the SEC permits
          such suspension and so orders, or (3) an emergency exists as
          determined by the SEC so that disposal of securities or determination
          of NAV is not reasonably practicable.

                                                                              37

Income dividends, capital gains distributions and tax
       status


          It is a policy of the Shares of the Portfolios to make distributions
          of substantially all of their respective investment income and any net
          realized capital gains. The Portfolios intend to qualify as regulated
          investment companies by satisfying certain requirements prescribed by
          Subchapter M of the Internal Revenue Code ("Code"). In addition, each
          Portfolio intends to comply with the diversification requirements of
          Code Section 817(h) related to the tax-deferred status of insurance
          company separate accounts.


          All income dividends and capital gains distributions, if any, on a
          Portfolio's Shares are reinvested automatically in additional Shares
          of that Portfolio at the NAV determined on the first business day
          following the record date.


          The Portfolios may purchase securities of certain foreign corporations
          considered to be passive foreign investment companies by the IRS. In
          order to avoid taxes and interest that must be paid by the Portfolios
          if these instruments appreciate in value, the Portfolios may make
          various elections permitted by the tax laws. However, these elections
          could require that the Portfolios recognize taxable income, which in
          turn must be distributed.


          Some foreign securities purchased by the Portfolios may be subject to
          foreign taxes which could reduce the yield on such securities. The
          amount of such foreign taxes is expected to be insignificant. The
          Portfolios may from year to year make the election permitted under
          Section 853 of the Code to pass through such taxes to shareholders. If
          such election is not made, any foreign taxes paid or accrued will
          represent an expense to each Portfolio which will reduce its
          investment company taxable income.

          Because Shares of the Portfolios can only be purchased through
          variable insurance contracts or qualified plans, it is anticipated
          that any income dividends or capital gains distributions will be

Principal shareholders



          The officers and Trustees of the Portfolios cannot directly own Shares
          of the Portfolios without purchasing an insurance contract through one
          of the participating insurance companies or through a qualified plan.
          As a result, such officers and Trustees as a group own less than 1% of
          the outstanding Shares of each Portfolio. As of April 3, 2000, all of
          the outstanding Shares of the Portfolios were owned by certain
          insurance company separate accounts or qualified plans. The percentage
          ownership of each separate account or plan owning more than 5% of the
          Shares of any Portfolio is as follows:

Miscellaneous information


          Each Portfolio is a series of the Trust, an open-end management
          investment company registered under the 1940 Act and organized as a
          Delaware business trust on May 20, 1993. As of the date of this SAI,
          the Trust is offering fourteen series of shares, known as
          "Portfolios," each of which consists of two or three classes of
          shares. Additional series and/or classes may be created from time to
          time.


SHARES OF THE TRUST

          The Trust is authorized to issue an unlimited number of shares of
          beneficial interest with a par value of $.001 per share for each
          series of the Trust. Shares of each Portfolio are fully paid and
          nonassessable when issued. Shares of a Portfolio participate equally
          in dividends and other distributions by the shares of such Portfolio,
          and in residual assets of that Portfolio in the event of liquidation.
          Shares of each Portfolio have no preemptive, conversion or
          subscription rights.


          The Portfolios each offer two or three classes of shares. The Shares
          discussed in this SAI are offered only in connection with investment
          in and payments under variable insurance contracts and to qualified
          retirement plans that require a fee from Portfolio assets to procure
          distribution and administrative services to contract owners and plan
          participants. A second class of shares, Retirement Shares, is offered
          only to qualified plans whose service providers require a fee from the
          Trust assets for providing certain services to plan participants. The
          third class of shares, Institutional Shares, is offered only in
          connection with investments in and payments under variable insurance
          contracts as well as other qualified retirement plans.


SHAREHOLDER MEETINGS

          The Trust does not intend to hold annual shareholder meetings.
          However, special meetings may be called for a specific Portfolio or
          for the Trust as a whole for purposes such as electing or removing
          Trustees, terminating or reorganizing the Trust, changing fundamental
          policies, or for any other purpose requiring a shareholder vote under
          the 1940 Act. Separate votes are taken by each Portfolio or class only
          if a matter affects or requires the vote of only that Portfolio or
          class or that Portfolio's or class' interest in the matter differs
          from the interest of other Portfolios of the Trust. A shareholder is
          entitled to one vote for each Share owned.

VOTING RIGHTS

          A participating insurance company issuing a variable insurance
          contract will vote shares in the separate account as required by law
          and interpretations thereof, as may be amended or changed from time to
          time. In accordance with current law and interpretations, a
          participating insurance company is required to request voting
          instructions from policy owners and must vote shares in the separate
          account, including shares for which no instructions have been
          received, in proportion to the voting instructions received.
          Additional information may be found in the participating insurance
          company's separate account prospectus.

          The Trustees are responsible for major decisions relating to each
          Portfolio's policies and objectives; the Trustees oversee the
          operation of each Portfolio by its officers and review the investment
          decisions of the officers.

          The present Trustees were elected by the initial trustee of the Trust
          on May 25, 1993, and were approved by the initial shareholder on May
          25, 1993, with the exception of Mr. Craig and Mr. Rothe who were
          appointed by the Trustees as of June 30, 1995 and as of January 1,
          1997, respectively. Under the Trust Instrument, each Trustee will
          continue in office until the termination of the Trust or his earlier
          death, retirement, resignation, bankruptcy, incapacity or removal.
          Vacancies will be filled by a majority of the remaining Trustees,
          subject to the 1940 Act. Therefore, no annual or regular meetings of
          shareholders normally will be held, unless otherwise required by the
          Trust Instrument or the 1940 Act. Subject to the

 40
<PAGE>

          foregoing, shareholders have the power to vote to elect or remove
          Trustees, to terminate or reorganize their Portfolio, to amend the
          Trust Instrument, to bring certain derivative actions and on any other
          matters on which a shareholder vote is required by the 1940 Act, the
          Trust Instrument, the Trust's Bylaws or the Trustees.

          As mentioned above in "Shareholder Meetings," each share of each
          portfolio of the Trust has one vote (and fractional votes for
          fractional shares). Shares of all portfolios of the Trust have
          noncumulative voting rights, which means that the holders of more than
          50% of the shares of all series of the Trust voting for the election
          of Trustees can elect 100% of the Trustees if they choose to do so
          and, in such event, the holders of the remaining shares will not be
          able to elect any Trustees.

INDEPENDENT ACCOUNTANTS

          PricewaterhouseCoopers LLP, 950 Seventeenth Street, Suite 2500,
          Denver, Colorado 80202, independent accountants for the Portfolios,
          audit the Portfolios' annual financial statements and prepare their
          tax returns.

REGISTRATION STATEMENT

          The Trust has filed with the SEC, Washington, D.C., a Registration
          Statement under the Securities Act of 1933, as amended, with respect
          to the securities to which this SAI relates. If further information is
          desired with respect to the Portfolios or such securities, reference
          is made to the Registration Statement and the exhibits filed as a part
          thereof.

                                                                              41

Performance information


          Quotations of average annual total return for the Shares of a
          Portfolio will be expressed in terms of the average annual compounded
          rate of return of a hypothetical investment in the Shares of such
          Portfolio over periods of 1, 5, and 10 years (up to the life of the
          Portfolio). These are the annual total rates of return that would
          equate the initial amount invested to the ending redeemable value.
          These rates of return are calculated pursuant to the following
          formula: P(1 + T)(n) = ERV (where P = a hypothetical initial payment
          of $1,000, T = the average annual total return, n = the number of
          years and ERV = the ending redeemable value of a hypothetical $1,000
          payment made at the beginning of the period). All total return figures
          reflect the deduction of a proportional share of expenses of the
          Shares of a Portfolio on an annual basis, and assume that all
          dividends and distributions are reinvested when paid. The average
          annual total return of the Shares of each Portfolio, computed as of
          December 31, 1999, is shown in the table below (with the exception of
          Global Life Sciences Portfolio and Global Technology Portfolio, which
          had not commenced operations as of December 31, 1999).



          The Service Shares commenced operations on December 31, 1999. The
          returns shown for the Service Shares of these Portfolios reflect the
          historical performance of a different class of shares (the
          Institutional Shares) prior to December 31, 1999, restated based on
          the Service Shares' estimated fees and expenses (ignoring any fee and
          expense limitations).

          Yield quotations for a Portfolio's Shares are based on the investment
          income per Share earned during a particular 30-day period (including
          dividends, if any, and interest), less expenses accrued during the
          period ("net investment income"), and are computed by dividing net
          investment income by the net asset value per share on the last day of
          the period, according to the following formula:

                              YIELD = 2[(a - b + 1)(6) - 1]
                                         -----
                                          cd

          where a = dividend and interest income
                b = expenses accrued for the period (net of reimbursements)
                c = average daily number of shares outstanding during the period
                    that were entitled to receive dividends
                d = maximum net asset value per share on the last day of the
                    period

          From time to time in advertisements or sales material, the Portfolios
          may discuss their performance ratings or other information as
          published by recognized mutual fund statistical rating services,
          including, but not limited to, Lipper Analytical Services, Inc.
          ("Lipper"), Ibbotson Associates, Micropal or Morningstar, Inc.
          ("Morningstar"), or by publications of general interest such as
          Forbes, Money, The Wall Street Journal, Mutual Funds Magazine,
          Kiplinger's or Smart Money. The Portfolios may also compare their
          performance to that of other selected mutual funds (for example, peer
          groups created by Lipper or Morningstar), mutual fund averages or
          recognized stock market indicators, including, but not limited to, the
          Standard & Poor's 500 Composite Stock Price Index, the Standard &
          Poor's MidCap 400 Index, the Dow Jones Industrial Average, the Lehman
          Brothers Government/Corporate Bond Index, the Lehman Brothers
          Government/Corporate 1-3 Year Bond Index, the Lehman Brothers Long
          Government/Corporate Bond Index, the Lehman Brothers Intermediate
          Government Bond Index, the Lehman Brothers Municipal Bond Index, the
          Russell 2000 Index and the NASDAQ composite. In addition, the
          Portfolios may compare their total return or yield to the yield on
          U.S. Treasury obligations and to the percentage change in the Consumer
          Price Index. Worldwide Growth Portfolio and International Growth
          Portfolio may also compare their performance to the record of global
          market indicators, such as the Morgan Stanley Capital International
          World Index or Morgan Stanley Capital International Europe,
          Australasia, Far East Index (EAFE(R) Index). Such performance ratings
          or comparisons may be made with funds that may have different
          investment restrictions, objectives, policies or techniques than the
          Portfolios and such other funds or market indicators may be comprised
          of securities that differ significantly from the Portfolios'
          investments.

EXPLANATION OF RATING CATEGORIES

          The following is a description of credit ratings issued by two of the
          major credit ratings agencies. Credit ratings evaluate only the safety
          of principal and interest payments, not the market value risk of lower
          quality securities. Credit rating agencies may fail to change credit
          ratings to reflect subsequent events on a timely basis. Although Janus
          Capital considers security ratings when making investment decisions,
          it also performs its own investment analysis and does not rely solely
          on the ratings assigned by credit agencies.

                                             outweighed by large uncertainties or major risk exposure to
                                             adverse conditions.
                D........................... In default.

                Investment Grade
                Aaa......................... Highest quality, smallest degree of investment risk.
                Aa.......................... High quality; together with Aaa bonds, they compose the
                                             high-grade bond group.
                A........................... Upper-medium grade obligations; many favorable investment
                                             attributes.
                Baa......................... Medium-grade obligations; neither highly protected nor
                                             poorly secured. Interest and principal appear adequate for
                                             the present but certain protective elements may be lacking
                                             or may be unreliable over any great length of time.
                Non-Investment Grade
                Ba.......................... More uncertain, with speculative elements. Protection of
                                             interest and principal payments not well safeguarded during
                                             good and bad times.
                B........................... Lack characteristics of desirable investment; potentially
                                             low assurance of timely interest and principal payments or
                                             maintenance of other contract terms over time.
                Caa......................... Poor standing, may be in default; elements of danger with
                                             respect to principal or interest payments.
                Ca.......................... Speculative in a high degree; could be in default or have
                                             other marked shortcomings.
                C........................... Lowest-rated; extremely poor prospects of ever attaining
                                             investment standing.

          Unrated securities will be treated as noninvestment grade securities
          unless the portfolio manager determines that such securities are the
          equivalent of investment grade securities. Securities that have
          received ratings from more than one agency are considered investment
          grade if at least one agency has rated the security investment grade.

Investment restrictions and investment strategies

INVESTMENT RESTRICTIONS

          The Portfolio has adopted certain fundamental investment restrictions
          that cannot be changed without shareholder approval. Shareholder
          approval means approval by the lesser of (i) more than 50% of the
          outstanding voting securities of the Trust (or the Portfolio or class
          of shares if a matter affects just the Portfolio or class of shares),
          or (ii) 67% or more of the voting securities present at a meeting if
          the holders of more than 50% of the outstanding voting securities of
          the Trust (or the Portfolio or class of shares) are present or
          represented by proxy.

          As used in the restrictions set forth below and as used elsewhere in
          this SAI, the term "U.S. Government Securities" shall have the meaning
          set forth in the Investment Company Act of 1940, as amended (the "1940
          Act"). The 1940 Act defines U.S. Government Securities as securities
          issued or guaranteed by the United States government, its agencies or
          instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized and municipal securities escrowed
          with or refunded with escrowed U.S. government securities.

          The Portfolio has adopted the following fundamental policies:

          (1) With respect to 75% of its assets, the Portfolio may not purchase
          a security other than a U.S. Government Security, if, as a result,
          more than 5% of its total assets would be invested in the securities
          of a single issuer or the Portfolio would own more than 10% of the
          outstanding voting securities of any single issuer. (As noted in the
          Prospectus, the Portfolio is currently subject to the greater
          diversification standards of Rule 2a-7, which are not fundamental.)

          (2) The Portfolio may not purchase securities if 25% or more of the
          value of its total assets would be invested in the securities of
          issuers conducting their principal business activities in the same
          industry; provided that: (i) there is no limit on investments in U.S.
          Government Securities or in obligations of domestic commercial banks
          (including U.S. branches of foreign banks subject to regulations under
          U.S. laws applicable to domestic banks and, to the extent that its
          parent is unconditionally liable for the obligation, foreign branches
          of U.S. banks); (ii) this limitation shall not apply to the
          Portfolio's investments in municipal securities; (iii) there is no
          limit on investment in issuers domiciled in a single country; (iv)
          financial service companies are classified according to the end users
          of their services (for example, automobile finance, bank finance and
          diversified finance are each considered to be a separate industry);
          and (v) utility companies are classified according to their services
          (for example, gas, gas transmission, electric, and telephone are each
          considered to be a separate industry).

          (3) The Portfolio may not act as an underwriter of securities issued
          by others, except to the extent that it may be deemed an underwriter
          in connection with the disposition of its portfolio securities.

          (4) The Portfolio may not lend any security or make any other loan if,
          as a result, more than 25% of its total assets would be lent to other
          parties (but this limitation does not apply to purchases of commercial
          paper, debt securities or repurchase agreements).

          (5) The Portfolio may not purchase or sell real estate or any interest
          therein, except that the Portfolio may invest in debt obligations
          secured by real estate or interests therein or securities issued by
          companies that invest in real estate or interests therein.

          (6) The Portfolio may borrow money for temporary or emergency purposes
          (not for leveraging) in an amount not exceeding 25% of the value of
          its total assets (including the amount borrowed) less liabilities
          (other than borrowings). If borrowings exceed 25% of the value of the
          Portfolio's total assets by reason of a decline in net assets, it will
          reduce its borrowings within three business days to the extent
          necessary to comply with the 25% limitation. Reverse repurchase
          agreements or the segregation of assets in connection with such
          agreements shall not be considered borrowing for the purposes of this
          limit.

<PAGE>

          (7) The Portfolio may, notwithstanding any other investment policy or
          restriction (whether or not fundamental), invest all of its assets in
          the securities of a single open-end management investment company with
          substantially the same fundamental investment objectives, policies and
          restrictions as the Portfolio.

          Investment restriction (1) is intended to reflect the requirements
          under Section 5(b)(1) of the 1940 Act for a diversified fund. Rule
          2a-7 provides that money market funds that comply with the
          diversification limits of Rule 2a-7 are deemed to comply with the
          diversification limits of Section 5(b)(1). Thus, the Portfolio
          interprets restriction (1) in accordance with Rule 2a-7. Accordingly,
          if securities are subject to a guarantee provided by a non-controlled
          person, the Rule 2a-7 diversification tests apply to the guarantor,
          and the diversification test in restriction (1) does not apply to the
          issuer.

          The Portfolio has adopted the following nonfundamental investment
          restrictions that may be changed by the Trustees without shareholder
          approval:

          (1) The Portfolio may not invest in securities or enter into
          repurchase agreements with respect to any securities if, as a result,
          more than 10% of its net assets would be invested in repurchase
          agreements not entitling the holder to payment of principal within
          seven days and in other securities that are not readily marketable
          ("illiquid securities"). The Trustees, or the Portfolio's investment
          adviser acting pursuant to authority delegated by the Trustees, may
          determine that a readily available market exists for certain
          securities such as securities eligible for resale pursuant to Rule
          144A under the Securities Act of 1933, or any successor to such rule,
          Section 4(2) commercial paper and municipal lease obligations.
          Accordingly, such securities may not be subject to the foregoing
          limitation.

          (2) The Portfolio may not purchase securities on margin, or make short
          sales of securities, except for short sales against the box and the
          use of short-term credit necessary for the clearance of purchases and
          sales of portfolio securities.

          (3) The Portfolio may not pledge, mortgage, hypothecate or encumber
          any of its assets except to secure permitted borrowings or in
          connection with permitted short sales.

          (4) The Portfolio may not invest in companies for the purpose of
          exercising control of management.

          Under the terms of an exemptive order received from the Securities and
          Exchange Commission ("SEC"), the Portfolio may borrow money from or
          lend money to other funds that permit such transactions and for which
          Janus Capital serves as investment adviser. All such borrowing and
          lending will be subject to the above limits. The Portfolio will borrow
          money through the program only when the costs are equal to or lower
          than the cost of bank loans. Interfund loans and borrowings normally
          extend overnight, but can have a maximum duration of seven days. The
          Portfolio will lend through the program only when the returns are
          higher than those available from other short-term instruments (such as
          repurchase agreements). The Portfolio may have to borrow from a bank
          at a higher interest rate if an interfund loan is called or not
          renewed. Any delay in repayment to a lending Portfolio could result in
          a lost investment opportunity or additional borrowing costs.

          For purposes of the Portfolio's policies on investing in particular
          industries, the Portfolio will rely primarily on industry or industry
          group classifications as published by Bloomberg L.P. To the extent
          that Bloomberg L.P. industry classifications are so broad that the
          primary economic characteristics in a single industry are materially
          different, the Portfolio may further classify issuers in accordance
          with industry classifications as published by the SEC.

                                                                               3

INVESTMENT STRATEGIES

          The Portfolio may invest only in "eligible securities" as defined in
          Rule 2a-7 adopted under the 1940 Act. Generally, an eligible security
          is a security that (i) is denominated in U.S. dollars and has a
          remaining maturity of 397 days or less (as calculated pursuant to Rule
          2a-7); (ii) is rated, or is issued by an issuer with short-term debt
          outstanding that is rated, in one of the two highest rating categories
          by any two nationally recognized statistical rating organizations
          ("NRSROs") or, if only one NRSRO has issued a rating, by that NRSRO
          (the "Requisite NRSROs") or is unrated and of comparable quality to a
          rated security, as determined by Janus Capital; and (iii) has been
          determined by Janus Capital to present minimal credit risks pursuant
          to procedures approved by the Trustees. In addition, the Portfolio
          will maintain a dollar-weighted average portfolio maturity of 90 days
          or less. A description of the ratings of some NRSROs appears in
          Appendix A.

          Under Rule 2a-7, the Portfolio may not invest more than five percent
          of its total assets in the securities of any one issuer other than
          U.S. Government Securities, provided that in certain cases it may
          invest more than 5% of its assets in a single issuer for a period of
          up to three business days. Investment in demand features, guarantees
          and other types of instruments or features are subject to the
          diversification limits under Rule 2a-7.

          Pursuant to Rule 2a-7, the Portfolio will invest at least 95% of its
          total assets in "first-tier" securities. First-tier securities are
          eligible securities that are rated, or are issued by an issuer with
          short-term debt outstanding that is rated, in the highest rating
          category by the Requisite NRSROs or are unrated and of comparable
          quality to a rated security. In addition, the Portfolio may invest in
          "second-tier" securities which are eligible securities that are not
          first-tier securities. However, the Portfolio may not invest in a
          second-tier security if immediately after the acquisition thereof it
          would have invested more than (i) the greater of one percent of its
          total assets or one million dollars in second-tier securities issued
          by that issuer, or (ii) five percent of its total assets in
          second-tier securities.

          The following discussion of types of securities in which the Portfolio
          may invest supplements and should be read in conjunction with the
          Prospectus.

Participation Interests

          The Portfolio may purchase participation interests in loans or
          securities in which it may invest directly. Participation interests
          are generally sponsored or issued by banks or other financial
          institutions. A participation interest gives the Portfolio an
          undivided interest in the underlying loans or securities in the
          proportion that the Portfolio's interest bears to the total principal
          amount of the underlying loans or securities. Participation interests,
          which may have fixed, floating or variable rates, may carry a demand
          feature backed by a letter of credit or guarantee of a bank or
          institution permitting the holder to tender them back to the bank or
          other institution. For certain participation interests, the Portfolio
          will have the right to demand payment, on not more than seven days'
          notice, for all or a part of the Portfolio's participation interest.
          The Portfolio intends to exercise any demand rights it may have upon
          default under the terms of the loan or security, to provide liquidity
          or to maintain or improve the quality of the Portfolio's investment
          portfolio. The Portfolio will only purchase participation interests
          that Janus Capital determines present minimal credit risks.

Variable and Floating Rate Notes

          The Portfolio also may purchase variable and floating rate demand
          notes of corporations, which are unsecured obligations redeemable upon
          not more than 30 days' notice. These obligations include master demand
          notes that permit investment of fluctuating amounts at varying rates
          of interest pursuant to direct

 4
<PAGE>

          arrangements with the issuer of the instrument. The issuer of these
          obligations often has the right, after a given period, to prepay the
          outstanding principal amount of the obligations upon a specified
          number of days' notice. These obligations generally are not traded,
          nor generally is there an established secondary market for these
          obligations. To the extent a demand note does not have a seven day or
          shorter demand feature and there is no readily available market for
          the obligation, it is treated as an illiquid investment.

          Securities with ultimate maturities of greater than 397 days may be
          purchased only pursuant to Rule 2a-7. Under that Rule, only those
          long-term instruments that have demand features which comply with
          certain requirements and certain variable rate U.S. Government
          Securities may be purchased. The rate of interest on securities
          purchased by the Portfolio may be tied to short-term Treasury or other
          government securities or indices on securities that are permissible
          investments of the Portfolio, as well as other money market rates of
          interest. The Portfolio will not purchase securities whose values are
          tied to interest rates or indices that are not appropriate for the
          duration and volatility standards of a money market fund.

Mortgage- and Asset-Backed Securities

          The Portfolio may invest in mortgage-backed securities, which
          represent an interest in a pool of mortgages made by lenders such as
          commercial banks, savings and loan institutions, mortgage bankers,
          mortgage brokers and savings banks. Mortgage-backed securities may be
          issued by governmental or government-related entities or by
          non-governmental entities such as banks, savings and loan
          institutions, private mortgage insurance companies, mortgage bankers
          and other secondary market issuers.

          Interests in pools of mortgage-backed securities differ from other
          forms of debt securities which normally provide for periodic payment
          of interest in fixed amounts with principal payments at maturity or
          specified call dates. In contrast, mortgage-backed securities provide
          periodic payments which consist of interest and, in most cases,
          principal. In effect, these payments are a "pass-through" of the
          periodic payments and optional prepayments made by the individual
          borrowers on their mortgage loans, net of any fees paid to the issuer
          or guarantor of such securities. Additional payments to holders of
          mortgage-backed securities are caused by prepayments resulting from
          the sale of the underlying residential property, refinancing or
          foreclosure, net of fees or costs which may be incurred.

          As prepayment rates of individual pools of mortgage loans vary widely,
          it is not possible to predict accurately the average life of a
          particular security. Although mortgage-backed securities are issued
          with stated maturities of up to forty years, unscheduled or early
          payments of principal and interest on the underlying mortgages may
          shorten considerably the effective maturities. Mortgage-backed
          securities may have varying assumptions for average life. The volume
          of prepayments of principal on a pool of mortgages underlying a
          particular security will influence the yield of that security, and the
          principal returned to the Portfolio may be reinvested in instruments
          whose yield may be higher or lower than that which might have been
          obtained had the prepayments not occurred. When interest rates are
          declining, prepayments usually increase, with the result that
          reinvestment of principal prepayments will be at a lower rate than the
          rate applicable to the original mortgage-backed security.

          The Portfolio may invest in mortgage-backed securities that are issued
          by agencies or instrumentalities of the U.S. government. The
          Government National Mortgage Association ("GNMA") is the principal
          federal government guarantor of mortgage-backed securities. GNMA is a
          wholly-owned U.S. government corporation within the Department of
          Housing and Urban Development. GNMA Certificates are debt securities
          which represent an interest in one mortgage or a pool of mortgages
          which are insured by the Federal Housing Administration or the Farmers
          Home Administration or are guaranteed by the Veterans Administration.
          The Portfolio may also invest in pools of conventional mortgages which
          are issued or

                                                                               5
<PAGE>

          guaranteed by agencies of the U.S. government. GNMA pass-through
          securities are considered to be riskless with respect to default in
          that (i) the underlying mortgage loan portfolio is comprised entirely
          of government-backed loans and (ii) the timely payment of both
          principal and interest on the securities is guaranteed by the full
          faith and credit of the U.S. government, regardless of whether or not
          payments have been made on the underlying mortgages. GNMA pass-through
          securities are, however, subject to the same market risk as comparable
          debt securities. Therefore, the market value of the Portfolio's GNMA
          securities can be expected to fluctuate in response to changes in
          prevailing interest rate levels.

          Residential mortgage loans are pooled also by the Federal Home Loan
          Mortgage Corporation ("FHLMC"). FHLMC is a privately managed, publicly
          chartered agency created by Congress in 1970 for the purpose of
          increasing the availability of mortgage credit for residential
          housing. FHLMC issues participation certificates ("PCs") which
          represent interests in mortgages from FHLMC's national portfolio. The
          mortgage loans in FHLMC's portfolio are not U.S. government backed;
          rather, the loans are either uninsured with loan-to-value ratios of
          80% or less, or privately insured if the loan-to-value ratio exceeds
          80%. FHLMC guarantees the timely payment of interest and ultimate
          collection of principal on FHLMC PCs; the U.S. government does not
          guarantee any aspect of FHLMC PCs.

          The Federal National Mortgage Association ("FNMA") is a
          government-sponsored corporation owned entirely by private
          shareholders. It is subject to general regulation by the Secretary of
          Housing and Urban Development. FNMA purchases residential mortgages
          from a list of approved seller/servicers which include savings and
          loan associations, savings banks, commercial banks, credit unions and
          mortgage bankers. FNMA guarantees the timely payment of principal and
          interest on the pass-through securities issued by FNMA; the U.S.
          government does not guarantee any aspect of the FNMA pass-through
          securities.

          The Portfolio may also invest in privately-issued mortgage-backed
          securities to the extent permitted by their investment restrictions.
          Mortgage-backed securities offered by private issuers include
          pass-through securities comprised of pools of conventional residential
          mortgage loans; mortgage-backed bonds which are considered to be debt
          obligations of the institution issuing the bonds and which are
          collateralized by mortgage loans; and collateralized mortgage
          obligations ("CMOs") which are collateralized by mortgage-backed
          securities issued by GNMA, FHLMC or FNMA or by pools of conventional
          mortgages.

          Asset-backed securities represent direct or indirect participation in,
          or are secured by and payable from, assets other than mortgage-backed
          assets such as motor vehicle installment sales contracts, installment
          loan contracts, leases of various types of real and personal property
          and receivables from revolving credit agreements (credit cards).
          Asset-backed securities have yield characteristics similar to those of
          mortgage-backed securities and, accordingly, are subject to many of
          the same risks.

Reverse Repurchase Agreements

          Reverse repurchase agreements are transactions in which the Portfolio
          sells a security and simultaneously commits to repurchase that
          security from the buyer at an agreed upon price on an agreed upon
          future date. The resale price in a reverse repurchase agreement
          reflects a market rate of interest that is not related to the coupon
          rate or maturity of the sold security. For certain demand agreements,
          there is no agreed upon repurchase date and interest payments are
          calculated daily, often based upon the prevailing overnight repurchase
          rate. The Portfolio will use the proceeds of reverse repurchase
          agreements only to satisfy unusually heavy redemption requests or for
          other temporary or emergency purposes without the necessity of selling
          portfolio securities.

          Generally, a reverse repurchase agreement enables the Portfolio to
          recover for the term of the reverse repurchase agreement all or most
          of the cash invested in the portfolio securities sold and to keep the

 6
<PAGE>

          interest income associated with those portfolio securities. Such
          transactions are only advantageous if the interest cost to the
          Portfolio of the reverse repurchase transaction is less than the cost
          of obtaining the cash otherwise. In addition, interest costs on the
          money received in a reverse repurchase agreement may exceed the return
          received on the investments made by the Portfolio with those monies.

When-Issued and Delayed Delivery Securities

          The Portfolio may purchase securities on a when-issued or delayed
          delivery basis. The Portfolio will enter into such transactions only
          when it has the intention of actually acquiring the securities. To
          facilitate such acquisitions, the Portfolio's custodian will segregate
          cash or high quality liquid assets in an amount at least equal to such
          commitments. On delivery dates for such transactions, the Portfolio
          will meet its obligations from maturities, sales of the segregated
          securities or from other available sources of cash. If it chooses to
          dispose of the right to acquire a when-issued security prior to its
          acquisition, the Portfolio could, as with the disposition of any other
          portfolio obligation, incur a gain or loss due to market fluctuation.
          At the time it makes the commitment to purchase securities on a
          when-issued or delayed delivery basis, the Portfolio will record the
          transaction as a purchase and thereafter reflect the value of such
          securities in determining its net asset value.

Investment Company Securities

          From time to time, the Portfolio may invest in securities of other
          investment companies. The Portfolio is subject to the provisions of
          Section 12(d)(1) of the 1940 Act. The Portfolio may invest in
          securities of money market funds managed by Janus Capital in excess of
          the limitations of Section 12(d)(1) under the terms of an SEC
          exemptive order obtained by Janus Capital and the Janus funds.

Debt Obligations


          Money Market Portfolio may invest in U.S. dollar denominated debt
          obligations. In general, sales of these securities may not be made
          absent registration under the Securities Act of 1933 or the
          availability of an appropriate exemption. Pursuant to Section 4(2) of
          the 1933 Act or Rule 144A adopted under the 1933 Act, however, some of
          these securities are eligible for resale to institutional investors,
          and accordingly, Janus Capital may determine that a liquid market
          exists for such a security pursuant to guidelines adopted by the
          Trustees.


Obligations of Financial Institutions

          The Portfolio may invest in obligations of financial institutions.
          Examples of obligations in which the Portfolio may invest include
          negotiable certificates of deposit, bankers' acceptances, time
          deposits and other obligations of U.S. banks (including savings and
          loan associations) having total assets in excess of one billion
          dollars and U.S. branches of foreign banks having total assets in
          excess of ten billion dollars. The Portfolio may also invest in
          Eurodollar and Yankee bank obligations as discussed below and other
          U.S. dollar-denominated obligations of foreign banks having total
          assets in excess of ten billion dollars that Janus Capital believes
          are of an investment quality comparable to obligations of U.S. banks
          in which the Portfolio may invest.

          Certificates of deposit represent an institution's obligation to repay
          funds deposited with it that earn a specified interest rate over a
          given period. Bankers' acceptances are negotiable obligations of a
          bank to pay a draft which has been drawn by a customer and are usually
          backed by goods in international trade. Time deposits are
          non-negotiable deposits with a banking institution that earn a
          specified interest rate over a given period. Fixed time deposits,
          which are payable at a stated maturity date and bear a fixed rate of
          interest, generally may be withdrawn on demand by the Portfolio but
          may be subject to early withdrawal

                                                                               7
<PAGE>

          penalties and that could reduce the Portfolio's yield. Unless there is
          a readily available market for them, time deposits that are subject to
          early withdrawal penalties and that mature in more than seven days
          will be treated as illiquid securities.

          Eurodollar bank obligations are dollar-denominated certificates of
          deposit or time deposits issued outside the U.S. capital markets by
          foreign branches of U.S. banks and by foreign banks. Yankee bank
          obligations are dollar-denominated obligations issued in the U.S.
          capital markets by foreign banks.

          Foreign, Eurodollar (and to a limited extent, Yankee) bank obligations
          are subject to certain sovereign risks. One such risk is the
          possibility that a foreign government might prevent dollar-denominated
          funds from flowing across its borders. Other risks include: adverse
          political and economic developments in a foreign country; the extent
          and quality of government regulation of financial markets and
          institutions; the imposition of foreign withholding taxes; and
          exploration or nationalization of foreign issuers.

U.S. Government Securities

          Money Market Portfolio may invest in U.S. Government Securities. U.S.
          Government Securities shall have the meaning set forth in the 1940
          Act. The 1940 Act defines U.S. Government Securities to include
          securities issued or guaranteed by the U.S. Government, its agencies
          and instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized by and municipal securities
          escrowed with or refunded with U.S. government securities. U.S.
          Government Securities in which the Portfolio may invest include U.S.
          Treasury securities and obligations issued or guaranteed by U.S.
          government agencies and instrumentalities that are backed by the full
          faith and credit of the U.S. government, such as those guaranteed by
          the Small Business Administration or issued by the Government National
          Mortgage Association. In addition, U.S. Government Securities in which
          the Portfolio may invest include securities supported primarily or
          solely by the creditworthiness of the issuer, such as securities of
          the Federal National Mortgage Association, the Federal Home Loan
          Mortgage Corporation and the Tennessee Valley Authority. There is no
          guarantee that the U.S. government will support securities not backed
          by its full faith and credit. Accordingly, although these securities
          have historically involved little risk of loss of principal if held to
          maturity, they may involve more risk than securities backed by the
          full faith and credit of the U.S. government.

Municipal Leases

          The Portfolio may invest in municipal leases. Municipal leases
          frequently have special risks not normally associated with general
          obligation or revenue bonds. Municipal leases are municipal securities
          which may take the form of a lease or an installment purchase or
          conditional sales contract. Municipal leases are issued by state and
          local governments and authorities to acquire a wide variety of
          equipment and facilities. Leases and installment purchase or
          conditional sale contracts (which normally provide for title to the
          leased asset to pass eventually to the government issuer) have evolved
          as a means for governmental issuers to acquire property and equipment
          without meeting the constitutional and statutory requirements for the
          issuance of debt. The debt-issuance limitations of many state
          constitutions and statutes are deemed to be inapplicable because of
          the inclusion in many leases or contracts of "non-appropriation"
          clauses that provide that the governmental issuer has no obligation to
          make future payments under the lease or contract unless money is
          appropriated for such purpose by the appropriate legislative body on a
          yearly or other periodic basis. The Portfolio will only purchase
          municipal leases subject to a non-appropriation clause when the
          payment of principal and accrued interest is backed by an
          unconditional irrevocable letter of credit, or guarantee of a bank or
          other entity that meets the criteria described in the Prospectus under
          "Taxable Investments."

 8
<PAGE>

          In evaluating municipal lease obligations, Janus Capital will consider
          such factors as it deems appropriate, including: (a) whether the lease
          can be canceled; (b) the ability of the lease obligee to direct the
          sale of the underlying assets; (c) the general creditworthiness of the
          lease obligor; (d) the likelihood that the municipality will
          discontinue appropriating funding for the leased property in the event
          such property is no longer considered essential by the municipality;
          (e) the legal recourse of the lease obligee in the event of such a
          failure to appropriate funding; (f) whether the security is backed by
          a credit enhancement such as insurance; and (g) any limitations which
          are imposed on the lease obligor's ability to utilize substitute
          property or services other than those covered by the lease obligation.
          If a lease is backed by an unconditional letter of credit or other
          unconditional credit enhancement, then Janus Capital may determine
          that a lease is an eligible security solely on the basis of its
          evaluation of the credit enhancement.

          Municipal leases, like other municipal debt obligations, are subject
          to the risk of non-payment. The ability of issuers of municipal leases
          to make timely lease payments may be adversely impacted in general
          economic downturns and as relative governmental cost burdens are
          allocated and reallocated among federal, state and local governmental
          units. Such non-payment would result in a reduction of income to the
          Portfolio, and could result in a reduction in the value of the
          municipal lease experiencing non-payment and a potential decrease in
          the net asset value of the Portfolio.

                                                                               9

Performance data

          The Portfolio may provide current annualized and effective annualized
          yield quotations of the Shares based on the Shares' daily dividends.
          These quotations may from time to time be used in advertisements,
          shareholder reports or other communications to shareholders. All
          performance information supplied by the Portfolio in advertising is
          historical and is not intended to indicate future returns.

          In performance advertising, the Portfolio may compare any of its
          performance information with data published by independent evaluators
          such as Morningstar, Inc., Lipper Analytical Services, Inc., or
          CDC/Wiesenberger, Donoghue's Money Fund Report or other companies
          which track the investment performance of investment companies ("Fund
          Tracking Companies"). The Portfolio may also compare its performance
          information with the performance of recognized stock, bond and other
          indices, including but not limited to the Municipal Bond Buyers
          Indices, the Salomon Brothers Bond Index, the Lehman Brothers Bond
          Index, the Standard & Poor's 500 Composite Stock Price Index, the Dow
          Jones Industrial Average, U.S. Treasury bonds, bills or notes and
          changes in the Consumer Price Index as published by the U.S.
          Department of Commerce. The Portfolio may refer to general market
          performance over past time periods such as those published by Ibbotson
          Associates (for instance, its "Stocks, Bonds, Bills and Inflation
          Yearbook"). The Portfolio may also refer in such materials to mutual
          fund performance rankings and other data published by Fund Tracking
          Companies. Performance advertising may also refer to discussions of
          the Portfolio and comparative mutual fund data and ratings reported in
          independent periodicals, such as newspapers and financial magazines.

          Any current yield quotation of the Portfolio's Shares which is used in
          such a manner as to be subject to the provisions of Rule 482(d) under
          the Securities Act of 1933, as amended, shall consist of an annualized
          historical yield, carried at least to the nearest hundredth of one
          percent, based on a specific seven calendar day period. The current
          yield of the Portfolio's Shares shall be calculated by (a) determining
          the net change during a seven calendar day period in the value of a
          hypothetical account having a balance of one share at the beginning of
          the period, (b) dividing the net change by the value of the account at
          the beginning of the period to obtain a base period return, and (c)
          multiplying the quotient by 365/7 (i.e., annualizing). For this
          purpose, the net change in account value will reflect the value of
          additional shares purchased with dividends declared on the original
          share and dividends declared on both the original share and any such
          additional shares, but will not reflect any realized gains or losses
          from the sale of securities or any unrealized appreciation or
          depreciation on portfolio securities. In addition, the Portfolio may
          advertise effective yield quotations. Effective yield quotations are
          calculated by adding 1 to the base period return, raising the sum to a
          power equal to 365/7, and subtracting 1 from the result (i.e.,
          compounding).

          Income calculated for the purpose of determining the yield of the
          Portfolio's Shares differs from income as determined for other
          accounting purposes. Because of the different accounting methods used,
          and because of the compounding assumed in yield calculations, the
          yield quoted for the Portfolio's Shares may differ from the rate of
          distribution the Shares paid over the same period or the rate of
          income reported in the Portfolio's financial statements.

          Although published yield information is useful to investors in
          reviewing the performance of the Portfolio's Shares, investors should
          be aware that the yield fluctuates from day to day and that the
          Share's yield for any given period is not an indication or
          representation by the Portfolio of future yields or rates of return on
          the Portfolio's Shares. Also, because Shares of the Portfolio may only
          be purchased through variable insurance contracts, the prospectus of
          the participating insurance company sponsoring such contract should be
          carefully reviewed for information on relevant charges and expenses.
          The Shares' yield is not fixed or guaranteed, and an investment in the
          Portfolio is not insured. Accordingly, the Shares' yield information
          may not necessarily be used to compare Portfolio Shares with
          investment alternatives which, like money market instruments or bank
          accounts, may provide a fixed rate of interest. In addition, because

Determination of net asset value

          Pursuant to the rules of the SEC, the Trustees have established
          procedures to stabilize the Portfolio's net asset value at $1.00 per
          Share. These procedures include a review of the extent of any
          deviation of net asset value per share as a result of fluctuating
          interest rates, based on available market rates, from the Portfolio's
          $1.00 amortized cost price per Share. Should that deviation exceed
          1/2 of 1%, the Trustees will consider whether any action should be
          initiated to eliminate or reduce material dilution or other unfair
          results to shareholders. Such action may include redemption of shares
          in kind, selling portfolio securities prior to maturity, reducing or
          withholding dividends and utilizing a net asset value per share as
          determined by using available market quotations. The Portfolio (i)
          will maintain a dollar-weighted average portfolio maturity of 90 days
          or less; (ii) will not purchase any instrument with a remaining
          maturity greater than 397 days or subject to a repurchase agreement
          having a duration of greater than 397 days; (iii) will limit portfolio
          investments, including repurchase agreements, to those U.S.
          dollar-denominated instruments that Janus Capital has determined
          present minimal credit risks pursuant to procedures established by the
          Trustees; and (iv) will comply with certain reporting and
          recordkeeping procedures. The Trust has also established procedures to
          ensure that portfolio securities meet the Portfolio's high quality
          criteria.

Investment adviser

          As stated in the Prospectus, the Portfolio has an Investment Advisory
          Agreement with Janus Capital, 100 Fillmore Street, Denver, Colorado
          80206-4928. The Advisory Agreement provides that Janus Capital will
          furnish continuous advice and recommendations concerning the
          Portfolio's investments, provide office space for the Portfolio, and
          pay the salaries, fees and expenses of all Portfolio officers and of
          those Trustees who are affiliated with Janus Capital. Janus Capital
          also may make payments to selected broker-dealer firms or institutions
          which were instrumental in the acquisition of shareholders for the
          Portfolio or which performed services with respect to shareholder
          accounts. The minimum aggregate size required for eligibility for such
          payments, and the factors in selecting the broker-dealer firms and
          institutions to which they will be made, are determined from time to
          time by Janus Capital. Janus Capital is also authorized to perform the
          management and administrative services necessary for the operation of
          the Portfolio.

          The Portfolio pays custodian agent fees and expenses, brokerage
          commissions and dealer spreads and other expenses in connection with
          the execution of Portfolio transactions, legal and accounting
          expenses, interest and taxes, registration fees, expenses of
          shareholders' meetings, and reports to shareholders, fees and expenses
          of Trustees who are not affiliated with Janus Capital, and other costs
          of complying with applicable laws regulating the sale of Portfolio
          shares. Pursuant to the Advisory Agreement, Janus Capital furnishes
          certain other services, including net asset value determination,
          portfolio accounting and record keeping for which the Portfolio may
          reimburse Janus Capital for its costs.

          The Portfolio has agreed to compensate Janus Capital for its advisory
          services by the monthly payment of an advisory fee at the annual rate
          of .25% of the Portfolio's average daily net assets. Janus Capital has
          agreed to reimburse the Portfolio by the amount, if any, that the
          Portfolio's normal operating expenses in any fiscal year, including
          the investment advisory fee but excluding brokerage commissions,
          interest, taxes and extraordinary expenses, exceed .50% of average
          daily net assets. Mortality risk, expense risk and other charges
          imposed by participating insurance companies are excluded from the
          above expense limitation. Janus Capital has agreed to continue such
          waivers until at least the next annual renewal of the advisory
          agreements.


          For the fiscal year ended December 31, 1999, the advisory fee was
          $137,596. For the fiscal years ended December 31, 1998 and December
          31, 1997, the advisory fees were $79,201 and $22,333, respectively.
          For the fiscal year ended December 31, 1997, Janus Capital waived
          $2,184.



          The Advisory Agreement is dated July 1, 1997 and will continue in
          effect until July 1, 2001, and thereafter from year to year so long as
          such continuance is approved annually by a majority of the Portfolio's
          Trustees who are not parties to the Advisory Agreement or interested
          persons of any such party, and by either a majority of the outstanding
          voting shares or the Trustees. The Advisory Agreement (i) may be
          terminated without the payment of any penalty by the Portfolio or
          Janus Capital on 60 days' written notice; (ii) terminates
          automatically in the event of its assignment; and (iii) generally, may
          not be amended without the approval by vote of a majority of the
          Trustees, including the Trustees who are not interested persons of the
          Portfolio or Janus Capital and, to the extent required by the 1940
          Act, the vote of a majority of the outstanding voting securities of
          the Portfolio.


          Janus Capital also acts as sub-adviser for a number of private-label
          mutual funds and provides separate account advisory services for
          institutional accounts. Investment decisions for each account managed
          by Janus Capital, including the Portfolio, are made independently from
          those for any other account that is or may in the future become
          managed by Janus Capital or its affiliates. If, however, a number of
          accounts managed by Janus Capital are contemporaneously engaged in the
          purchase or sale of the same security, the orders may be aggregated
          and/or the transactions may be averaged as to price and allocated
          equitably to each account. In some cases, this policy might adversely
          affect the price paid or received by an account or

                                                                              13

          the size of the position obtained or liquidated for an account.
          Pursuant to an exemptive order granted by the SEC, the Portfolio and
          other funds advised by Janus Capital may also transfer daily
          uninvested cash balances into one or more joint trading accounts.
          Assets in the joint trading accounts are invested in money market
          instruments and the proceeds are allocated to the participating funds
          on a pro rata basis.


          Kansas City Southern Industries, Inc. ("KCSI"), indirectly through its
          wholly owned subsidiary, Stilwell Financial Inc., owns approximately
          81% of the outstanding voting stock of Janus Capital. KCSI is a
          publicly traded holding company whose primary subsidiaries are engaged
          in transportation, information processing and financial services.
          Thomas H. Bailey, President and Chairman of the Board of Janus
          Capital, owns approximately 12% of Janus Capital's voting stock and,
          by agreement with KCSI, selects at least a majority of Janus Capital's
          Board.



          KCSI has announced its intention to separate its transportation and
          financial services businesses. KCSI anticipates the separation to be
          completed in the first half of 2000.


          Each account managed by Janus Capital has its own investment objective
          and is managed in accordance with that objective by a particular
          portfolio manager or team of portfolio managers. As a result, from
          time to time two or more different managed accounts may pursue
          divergent investment strategies with respect to investments or
          categories of investments.


          Janus Capital does not permit portfolio managers to purchase and sell
          securities for their own accounts except under the limited exceptions
          contained in the Portfolio's Code of Ethics ("Code"). The Portfolio's
          Code of Ethics is on file with and available from the SEC through the
          SEC Web site at www.sec.gov. The Code applies to Directors/ Trustees
          of Janus Capital and the Portfolios and employees of Janus Capital and
          the Trust, and requires investment personnel and officers of Janus
          Capital, inside Directors/Trustees of Janus Capital and the Portfolio
          and certain other designated employees deemed to have access to
          current trading information to pre-clear all transactions in
          securities not otherwise exempt under the Code. Requests for trading
          authorization will be denied when, among other reasons, the proposed
          personal transaction would be contrary to the provisions of the Code
          or would be deemed to adversely affect any transaction then known to
          be under consideration for or to have been effected on behalf of any
          client account, including the Portfolio.



          In addition to the pre-clearance requirement described above, the Code
          subjects such personnel, to various trading restrictions and reporting
          obligations. All reportable transactions are required to be reviewed
          for compliance with the Code. Those persons also may be required under
          certain circumstances to forfeit their profits made from personal
          trading.



          The provisions of the Code are administered by and subject to
          exceptions authorized by Janus Capital.

Custodian, transfer agent and certain affiliations

          Citibank, N.A., 111 Wall Street, 24th Floor, Zone 5, New York, NY
          10043, is the Portfolio's custodian. The custodian holds the
          Portfolio's assets in safekeeping and collects and remits the income
          thereon, subject to the instructions of the Portfolio.

          Janus Service Corporation, P.O. Box 173375, Denver, Colorado
          80217-3375, a wholly-owned subsidiary of Janus Capital, is the
          Portfolio's transfer agent. In addition, Janus Service provides
          certain other administrative, recordkeeping and shareholder relations
          services to the Portfolio. Janus Service is not compensated for its
          services with respect to the Shares except for out-of-pocket costs.

          Janus Distributors, Inc., 100 Fillmore Street, Denver, Colorado
          80206-4928, a wholly-owned subsidiary of Janus Capital, is a
          distributor of the Portfolio. Janus Distributors is registered as a
          broker-dealer under the Securities Exchange Act of 1934 and is a
          member of the National Association of Securities Dealers, Inc.


          The Portfolio pays DST Systems, Inc., a subsidiary of KCSI, license
          fees at the annual rate of $3.98 per shareholder account for the use
          of DST's accounting system. The Portfolio also pays DST $1.10 per
          closed shareholder account. The Portfolio pays DST for the use of its
          portfolio and fund accounting system a monthly base fee of $250 to
          $1,250 per month based on the number of Janus funds using the system
          and an asset charge of $1 per million dollars of net assets (not to
          exceed $500 per month).


          The Trustees have authorized the Portfolio to use another affiliate of
          DST as introducing broker for certain Portfolio transactions as a
          means to reduce Portfolio expenses through credits against the charges
          of DST and its affiliates with regard to commissions earned by such
          affiliate. See "Portfolio Transactions and Brokerage."

                                                                              15

Portfolio transactions and brokerage

          Decisions as to the assignment of portfolio business for the Portfolio
          and negotiation of its commission rates are made by Janus Capital
          whose policy is to obtain the "best execution" (prompt and reliable
          execution at the most favorable security price) of all portfolio
          transactions.

          In selecting brokers and dealers and in negotiating commissions, Janus
          Capital considers a number of factors, including but not limited to:
          Janus Capital's knowledge of currently available negotiated commission
          rates or prices of securities currently available and other current
          transaction costs; the nature of the security being traded; the size
          and type of the transaction; the nature and character of the markets
          for the security to be purchased or sold; the desired timing of the
          trade; the activity existing and expected in the market for the
          particular security; confidentiality; the quality of the execution,
          clearance and settlement services; financial stability of the broker
          or dealer; the existence of actual or apparent operational problems of
          any broker or dealer; and research products or services provided. In
          recognition of the value of the foregoing factors, Janus Capital may
          place portfolio transactions with a broker or dealer with whom it has
          negotiated a commission that is in excess of the commission another
          broker or dealer would have charged for effecting that transaction if
          Janus Capital determines in good faith that such amount of commission
          was reasonable in relation to the value of the brokerage and research
          provided by such broker or dealer viewed in terms of either that
          particular transaction or of the overall responsibilities of Janus
          Capital. These research and other services may include, but are not
          limited to, general economic and security market reviews, industry and
          company reviews, evaluations of securities, recommendations as to the
          purchase and sale of securities, and access to third party
          publications, computer and electronic equipment and software. Research
          received from brokers or dealers is supplemental to Janus Capital's
          own research efforts.


          For the fiscal years ended December 31, 1999, December 31, 1998 and
          December 31, 1997, the Portfolio did not incur any brokerage
          commissions. The Portfolio generally buys and sells securities in
          principal transactions, in which no commissions are paid. However, the
          Portfolio may engage an agent and pay commissions for such
          transactions if Janus Capital believes that the net result of the
          transaction to the Portfolio will be no less favorable than that of
          contemporaneously available principle transactions.


          Janus Capital may use research products and services in servicing
          other accounts in addition to the Portfolio. If Janus Capital
          determines that any research product or service has a mixed use, such
          that it also serves functions that do not assist in the investment
          decision-making process, Janus Capital may allocate the costs of such
          service or product accordingly. Only that portion of the product or
          service that Janus Capital determines will assist it in the investment
          decision-making process may be paid for in brokerage commission
          dollars. Such allocation may create a conflict of interest for Janus
          Capital.

          Janus Capital may consider sales of Portfolio shares or shares of
          other Janus funds by a broker-dealer or the recommendation of a
          broker-dealer to its customers that they purchase such shares as a
          factor in the selection of broker-dealers to execute Portfolio
          transactions. Janus Capital may also consider payments made by brokers
          effecting transactions for a Portfolio i) to the Portfolio or ii) to
          other persons on behalf of the Portfolio for services provided to the
          Portfolio for which it would be obligated to pay. In placing portfolio
          business with such broker-dealers, Janus Capital will seek the best
          execution of each transaction.

          When the Portfolio purchases or sells a security in the
          over-the-counter market, the transaction takes place directly with a
          principal market-maker, without the use of a broker, except in those
          circumstances where in the opinion of Janus Capital better prices and
          executions will be achieved through the use of a broker.

          The Trustees are responsible for major decisions relating to the
          Portfolio's objective, policies and techniques. The Trustees also
          supervise the operation of the Portfolio by its officers and review
          the investment decisions of the officers although they do not actively
          participate on a regular basis in making such decisions.

          The Trust's Executive Committee shall have and may exercise all the
          powers and authority of the Trustees except for matters requiring
          action by all Trustees pursuant to the Trust's Bylaws or Trust
          Instrument, Delaware law or the 1940 Act.

          The Money Market Funds Committee, consisting of Messrs. Loo, Mullen,
          and Rothe monitors the compliance with policies and procedures adopted
          particularly for money market funds.

          The following table shows the aggregate compensation earned by and
          paid to each Trustee by the Portfolio and all funds advised and
          sponsored by Janus Capital (collectively, the "Janus Funds") for the
          periods indicated. None of the Trustees receive pension or retirement
          benefits from the Portfolio or the Janus Funds.

Purchase of Shares

          Shares of the Portfolio can be purchased only by i) the separate
          accounts of participating insurance companies for the purpose of
          funding variable insurance contracts and ii) certain qualified
          retirement plans. Participating insurance companies and certain other
          designated organizations are authorized to receive purchase orders on
          the Portfolio's behalf, and those organizations are authorized to
          designate their agents and affiliates as intermediaries to receive
          purchase orders. Purchase orders are deemed received by the Portfolio
          when authorized organizations, their agents or affiliates receive the
          order. The Portfolio is not responsible for the failure of any
          designated organization or its agents or affiliates to carry out its
          obligations to its customers. Shares of the Portfolio are purchased at
          the NAV per share as determined at the close of regular trading
          session of the New York Stock Exchange next occurring after a purchase
          order is received and accepted by the Portfolio or its authorized
          agent. In order to receive a day's dividend, your order must be
          received by the close of the regular trading session of the NYSE. The
          prospectus for your insurance company's separate account or your plan
          documents contain detailed information about investing in the
          Portfolio.

Redemption of Shares


          Redemptions, like purchases, may only be effected through the separate
          accounts of participating insurance companies or qualified retirement
          plans. Participating insurance companies and certain designated
          organizations are authorized to receive redemption orders on the
          Portfolio's behalf and those organizations are authorized to designate
          their agents and affiliates as intermediaries to receive redemption
          orders. Redemption orders are deemed received by the Portfolio when
          authorized organizations, their agents or affiliates receive the
          order. The Portfolio is not responsible for the failure of any
          designated organization or its agents or affiliates to carry out its
          obligations to its customers. Shares normally will be redeemed for
          cash, although the Portfolio retains the right to redeem some or all
          of its shares in kind under unusual circumstances, in order to protect
          the interests of remaining shareholders, or to accommodate a request
          by a particular shareholder that does not adversely affect the
          interest of the remaining shareholders by delivery of securities
          selected from its assets at its discretion. However, the Portfolio is
          governed by Rule 18f-1 under the 1940 Act, which requires the
          Portfolio to redeem shares solely in cash up to the lesser of $250,000
          or 1% of the net asset value of the Portfolio during any 90-day period
          for any one shareholder. Should redemptions by any shareholder exceed
          such limitation, their Portfolio will have the option of redeeming the
          excess in cash or in kind. If shares are redeemed in kind, the
          redeeming shareholder might incur brokerage costs in converting the
          assets to cash. The method of valuing securities used to make
          redemptions in kind will be the same as the method of valuing
          portfolio securities described under "Determination of Net Asset
          Value" and such valuation will be made as of the same time the
          redemption price is determined.


          The right to require the Portfolio to redeem its shares may be
          suspended, or the date of payment may be postponed, whenever (1)
          trading on the NYSE is restricted, as determined by the SEC, or the
          NYSE is closed except for holidays and weekends, (2) the SEC permits
          such suspension and so orders, or (3) an emergency exists as
          determined by the SEC so that disposal of securities or determination
          of NAV is not reasonably practicable.

                                                                              23

Dividends and tax status

          Dividends representing substantially all of the net investment income
          and any net realized gains on sales of securities are declared daily,
          Saturdays, Sundays and holidays included, and distributed on the last
          business day of each month. If a month begins on a Saturday, Sunday,
          or holiday, dividends for those days are declared at the end of the
          preceding month and distributed on the first business day of the
          month. The Portfolio intends to qualify as a regulated investment
          company by satisfying certain requirements prescribed by Subchapter M
          of the Code. In addition, the Portfolio intends to comply with the
          diversification requirements of Internal Revenue Code Section 817(h)
          related to the tax-deferred status of insurance company separate
          accounts.

          All income dividends on the Portfolio's Shares are reinvested
          automatically in additional Shares of the Portfolio at the NAV
          determined on the first business day following the record date.

          Because Shares of the Portfolio can only be purchased through variable
          insurance contracts or qualified plans, it is anticipated that any
          income dividends or capital gains distributions will be exempt from
          current taxation if left to accumulate within such contracts or plans.
          See the prospectus for the separate account of the related insurance
          company or the plan documents for additional information.

Principal shareholders


          The officers and Trustees of the Portfolio cannot directly own Shares
          of the Portfolio without purchasing an insurance contract through one
          of the participating insurance companies or through a qualified plan.
          As a result, such officers and Trustees as a group own less than 1% of
          the outstanding Shares of the Portfolio. As of April 3, 2000, all of
          the outstanding Shares of the Portfolio were owned by certain
          insurance company separate accounts or qualified plans. The percentage
          ownership of each separate account or qualified plan owning more than
          5% of the Shares of the Portfolio is as follows:



          Western Reserve Life, 201 Highland Avenue, Clearwater, FL 34618, owned
          57.66% of the outstanding Shares of the Portfolio. National Integrity
          Life Insurance Company, 515 West Market Street, 8th Floor, Louisville,
          KY 40202, owned 42.34% of the outstanding Shares of the Portfolio.


          No qualified plan owned more than 10% of the shares of the Trust as a
          whole.

          The Shares held by the separate accounts of each insurance company,
          including Shares for which no voting instructions have been received,
          will be voted by each insurance company in proportion to instructions
          received from contract owners.

                                                                              25

Miscellaneous information


          The Portfolio is an open-end management investment company registered
          under the 1940 Act as a series of the Trust, which was organized as a
          Delaware business trust on May 20, 1993. The Trust Instrument permits
          the Trustees to issue an unlimited number of shares of beneficial
          interest from an unlimited number of series and classes of shares. As
          of the date of this SAI, the Trust consists of fourteen series of
          shares, known as "portfolios," in two or three classes. Additional
          series and/or classes may be created from time to time.


SHARES OF THE TRUST

          The Trust is authorized to issue an unlimited number of shares of
          beneficial interest with a par value of $0.001 per share for each
          series of the Trust. Shares of each series of the Trust are fully paid
          and nonassessable when issued. The Shares of the Portfolio participate
          equally in dividends and other distributions by the Portfolio, and in
          residual assets of the Portfolio in the event of liquidation. Shares
          of the Portfolio have no preemptive, conversion or subscription
          rights.


          The Portfolio currently offers two or three classes of shares. The
          Shares discussed in this SAI are offered only in connection with
          investment in and payments under variable contracts and life insurance
          contracts, as well as certain qualified retirement plans. A second
          class of shares, Retirement Shares, are offered only to certain other
          participant directed qualified plans whose service providers require a
          fee from Trust assets for providing certain services to plan
          participants.


SHAREHOLDER MEETINGS

          The Trust does not intend to hold annual shareholder meetings.
          However, special meetings may be called for the Portfolio or for the
          Trust as a whole for purposes such as electing or removing Trustees,
          terminating or reorganizing the Trust, changing fundamental policies,
          or for any other purpose requiring a shareholder vote under the 1940
          Act. Separate votes are taken by each Portfolio or class only if a
          matter affects or requires the vote of only that Portfolio or class or
          that Portfolio's or class' interest in the matter differs from the
          interest of the other portfolios or class of the Trust. A shareholder
          is entitled to one vote for each share owned.

VOTING RIGHTS

          A participating insurance company issuing a variable insurance
          contract will vote shares in the separate account as required by law
          and interpretations thereof, as may be amended or changed from time to
          time. In accordance with current law and interpretations, a
          participating insurance company is required to request voting
          instructions from policy owners and must vote shares in the separate
          account, including shares for which no instructions have been
          received, in proportion to the voting instructions received.
          Additional information may be found in the participating insurance
          company's separate account prospectus.

          The Trustees are responsible for major decisions relating to the
          Portfolio's policies and objectives; the Trustees oversee the
          operation of the Portfolio by its officers.

          The present Trustees were elected by the initial trustee of the Trust
          on May 25, 1993, and were approved by the initial shareholder on May
          25, 1993 with the exception of Mr. Craig and Mr. Rothe who were
          appointed by the Trustees as of June 30, 1995 and January 1, 1997,
          respectively. Under the Trust Instrument, each Trustee will continue
          in office until the termination of the Trust or his earlier death,
          retirement, resignation, bankruptcy, incapacity or removal. Vacancies
          will be filled by a majority of the remaining Trustees, subject to the
          1940 Act. Therefore, no annual or regular meetings of shareholders
          normally will be held, unless otherwise required by the Trust
          Instrument or the 1940 Act. Subject to the foregoing, shareholders
          have the power to vote to elect or remove Trustees, to terminate or
          reorganize the

 26
<PAGE>

          Portfolio, to amend the Trust Instrument, to bring certain derivative
          actions and on any other matters on which a shareholder vote is
          required by the 1940 Act, the Trust Instrument, the Trust's Bylaws or
          the Trustees.

          As mentioned in "Shareholder Meetings", each share of each portfolio
          of the Trust has one vote (and fractional votes for fractional
          shares). Shares of all portfolios of the Trust have noncumulative
          voting rights, which means that the holders of more than 50% of the
          shares of all portfolios of the Trust voting for the election of
          Trustees can elect 100% of the Trustees if they choose to do so and,
          in such event, the holders of the remaining shares will not be able to
          elect any Trustees. Each portfolio or class of the Trust will vote
          separately only with respect to those matters that affect only that
          portfolio or class or if the interest of a portfolio or class in the
          matter differs from the interests of other portfolios or classes of
          the Trust.

Appendix A

DESCRIPTION OF SECURITIES RATINGS

Moody's and Standard & Poor's

          MUNICIPAL AND CORPORATE BONDS AND MUNICIPAL LOANS

          The two highest ratings of Standard & Poor's Ratings Services ("S&P")
          for municipal and corporate bonds are AAA and AA. Bonds rated AAA have
          the highest rating assigned by S&P to a debt obligation. Capacity to
          pay interest and repay principal is extremely strong. Bonds rated AA
          have a very strong capacity to pay interest and repay principal and
          differ from the highest rated issues only in a small degree. The AA
          rating may be modified by the addition of a plus (+) or minus (-) sign
          to show relative standing within that rating category.

          The two highest ratings of Moody's Investors Service, Inc. ("Moody's")
          for municipal and corporate bonds are Aaa and Aa. Bonds rated Aaa are
          judged by Moody's to be of the best quality. Bonds rated Aa are judged
          to be of high quality by all standards. Together with the Aaa group,
          they comprise what are generally known as high-grade bonds. Moody's
          states that Aa bonds are rated lower than the best bonds because
          margins of protection or other elements make long-term risks appear
          somewhat larger than Aaa securities. The generic rating Aa may be
          modified by the addition of the numerals 1, 2 or 3. The modifier 1
          indicates that the security ranks in the higher end of the Aa rating
          category; the modifier 2 indicates a mid-range ranking; and the
          modifier 3 indicates that the issue ranks in the lower end of such
          rating category.

          SHORT TERM MUNICIPAL LOANS

          S&P's highest rating for short-term municipal loans is SP-1. S&P
          states that short-term municipal securities bearing the SP-1
          designation have a strong capacity to pay principal and interest.
          Those issues rated SP-1 which are determined to possess a very strong
          capacity to pay debt service will be given a plus (+) designation.
          Issues rated SP-2 have satisfactory capacity to pay principal and
          interest with some vulnerability to adverse financial and economic
          changes over the term of the notes.

          Moody's highest rating for short-term municipal loans is MIG-1/VMIG-1.
          Moody's states that short-term municipal securities rated MIG-1/VMIG-1
          are of the best quality, enjoying strong protection from established
          cash flows of funds for their servicing or from established and
          broad-based access to the market for refinancing, or both. Loans
          bearing the MIG-2/VMIG-2 designation are of high quality, with margins
          of protection ample although not so large as in the MIG-1/VMIG-1
          group.

          OTHER SHORT-TERM DEBT SECURITIES

          Prime-1 and Prime-2 are the two highest ratings assigned by Moody's
          for other short-term debt securities and commercial paper, and A-1 and
          A-2 are the two highest ratings for commercial paper assigned by S&P.
          Moody's uses the numbers 1, 2 and 3 to denote relative strength within
          its highest classification of Prime, while S&P uses the numbers 1, 2
          and 3 to denote relative strength within its highest classification of
          A. Issuers rated Prime-1 by Moody's have a superior ability for
          repayment of senior short-term debt obligations and have many of the
          following characteristics: leading market positions in
          well-established industries, high rates of return on funds employed,
          conservative capitalization structure with moderate reliance on debt

Appendix B

DESCRIPTION OF MUNICIPAL SECURITIES

          MUNICIPAL NOTES generally are used to provide for short-term capital
          needs and usually have maturities of one year or less. They include
          the following:

          1. Project Notes, which carry a U.S. government guarantee, are issued
          by public bodies (called "local issuing agencies") created under the
          laws of a state, territory, or U.S. possession. They have maturities
          that range up to one year from the date of issuance. Project Notes are
          backed by an agreement between the local issuing agency and the
          Federal Department of Housing and Urban Development. These Notes
          provide financing for a wide range of financial assistance programs
          for housing, redevelopment, and related needs (such as low-income
          housing programs and renewal programs).

          2. Tax Anticipation Notes are issued to finance working capital needs
          of municipalities. Generally, they are issued in anticipation of
          various seasonal tax revenues, such as income, sales, use and business
          taxes, and are payable from these specific future taxes.

          3. Revenue Anticipation Notes are issued in expectation of receipt of
          other types of revenues, such as Federal revenues available under the
          Federal Revenue Sharing Programs.

          4. Bond Anticipation Notes are issued to provide interim financing
          until long-term financing can be arranged. In most cases, the
          long-term bonds then provide the money for the repayment of the Notes.

          5. Construction Loan Notes are sold to provide construction financing.
          After successful completion and acceptance, many projects receive
          permanent financing through the Federal Housing Administration under
          the Federal National Mortgage Association ("Fannie Mae") or the
          Government National Mortgage Association ("Ginnie Mae").

          6. Tax-Exempt Commercial Paper is a short-term obligation with a
          stated maturity of 365 days or less. It is issued by agencies of state
          and local governments to finance seasonal working capital needs or as
          short-term financing in anticipation of longer term financing.

          MUNICIPAL BONDS, which meet longer term capital needs and generally
          have maturities of more than one year when issued, have three
          principal classifications:

          1. General Obligation Bonds are issued by such entities as states,
          counties, cities, towns, and regional districts. The proceeds of these
          obligations are used to fund a wide range of public projects,
          including construction or improvement of schools, highways and roads,
          and water and sewer systems. The basic security behind General
          Obligation Bonds is the issuer's pledge of its full faith and credit
          and taxing power for the payment of principal and interest. The taxes
          that can be levied for the payment of debt service may be limited or
          unlimited as to the rate or amount of special assessments.

          2. Revenue Bonds in recent years have come to include an increasingly
          wide variety of types of municipal obligations. As with other kinds of
          municipal obligations, the issuers of revenue bonds may consist of
          virtually any form of state or local governmental entity, including
          states, state agencies, cities, counties, authorities of various
          kinds, such as public housing or redevelopment authorities, and
          special districts, such as water, sewer or sanitary districts.
          Generally, revenue bonds are secured by the revenues or net revenues
          derived from a particular facility, group of facilities, or, in some
          cases, the proceeds of a special excise or other specific revenue
          source. Revenue bonds are issued to finance a wide variety of capital
          projects including electric, gas, water and sewer systems; highways,
          bridges, and tunnels; port and airport facilities; colleges and
          universities; and hospitals. Many of these bonds provide additional
          security in the form of a debt service reserve fund to be used to make
          principal and interest payments. Various forms of credit enhancement,
          such as a bank letter of credit or municipal bond insurance, may also
          be employed in revenue bond issues. Housing authorities have a wide
          range of security, including partially or fully insured

                                                                              31
<PAGE>

          mortgages, rent subsidized and/or collateralized mortgages, and/or the
          net revenues from housing or other public projects. Some authorities
          provide further security in the form of a state's ability (without
          obligation) to make up deficiencies in the debt service reserve fund.

          In recent years, revenue bonds have been issued in large volumes for
          projects that are privately owned and operated (see 3 below).

          3. Private Activity Bonds are considered municipal bonds if the
          interest paid thereon is exempt from Federal income tax and are issued
          by or on behalf of public authorities to raise money to finance
          various privately operated facilities for business and manufacturing,
          housing and health. These bonds are also used to finance public
          facilities such as airports, mass transit systems and ports. The
          payment of the principal and interest on such bonds is dependent
          solely on the ability of the facility's user to meet its financial
          obligations and the pledge, if any, of real and personal property as
          security for such payment.

          While, at one time, the pertinent provisions of the Internal Revenue
          Code permitted private activity bonds to bear tax-exempt interest in
          connection with virtually any type of commercial or industrial project
          (subject to various restrictions as to authorized costs, size
          limitations, state per capita volume restrictions, and other matters),
          the types of qualifying projects under the Code have become
          increasingly limited, particularly since the enactment of the Tax
          Reform Act of 1986. Under current provisions of the Code, tax-exempt
          financing remains available, under prescribed conditions, for certain
          privately owned and operated rental multi-family housing facilities,
          nonprofit hospital and nursing home projects, airports, docks and
          wharves, mass commuting facilities and solid waste disposal projects,
          among others, and for the refunding (that is, the tax-exempt
          refinancing) of various kinds of other private commercial projects
          originally financed with tax-exempt bonds. In future years, the types
          of projects qualifying under the Code for tax-exempt financing are
          expected to become increasingly limited.

          Because of terminology formerly used in the Internal Revenue Code,
          virtually any form of private activity bond may still be referred to
          as an "industrial development bond," but more and more frequently
          revenue bonds have become classified according to the particular type
          of facility being financed, such as hospital revenue bonds, nursing
          home revenue bonds, multi-family housing revenues bonds, single family
          housing revenue bonds, industrial development revenue bonds, solid
          waste resource recovery revenue bonds, and so on.

          OTHER MUNICIPAL OBLIGATIONS, incurred for a variety of financing
          purposes, include: municipal leases, which may take the form of a
          lease or an installment purchase or conditional sale contract, are
          issued by state and local governments and authorities to acquire a
          wide variety of equipment and facilities such as fire and sanitation
          vehicles, telecommunications equipment and other capital assets.
          Municipal leases frequently have special risks not normally associated
          with general obligation or revenue bonds. Leases and installment
          purchase or conditional sale contracts (which normally provide for
          title to the leased asset to pass eventually to the government issuer)
          have evolved as a means for governmental issuers to acquire property
          and equipment without meeting the constitutional and statutory
          requirements for the issuance of debt. The debt-issuance limitations
          of many state constitutions and statutes are deemed to be inapplicable
          because of the inclusion in many leases or contracts of
          "non-appropriation" clauses that provide that the governmental issuer
          has no obligation to make future payments under the lease or contract
          unless money is appropriated for such purpose by the appropriate
          legislative body on a yearly or other periodic basis. To reduce this
          risk, the Fund will only purchase municipal leases subject to a
          non-appropriation clause when the payment of principal and accrued
          interest is backed by an unconditional irrevocable letter of credit,
          or guarantee of a bank or other entity that meets the criteria
          described in the Prospectus.

<PAGE>

          Tax-exempt bonds are also categorized according to whether the
          interest is or is not includible in the calculation of alternative
          minimum taxes imposed on individuals, according to whether the costs
          of acquiring or carrying the bonds are or are not deductible in part
          by banks and other financial institutions, and according to other
          criteria relevant for Federal income tax purposes. Due to the
          increasing complexity of Internal Revenue Code and related
          requirements governing the issuance of tax-exempt bonds, industry
          practice has uniformly required, as a condition to the issuance of
          such bonds, but particularly for revenue bonds, an opinion of
          nationally recognized bond counsel as to the tax-exempt status of
          interest on the bonds.

                                                                              33

Investment restrictions and investment strategies

INVESTMENT RESTRICTIONS

          The Portfolio has adopted certain fundamental investment restrictions
          that cannot be changed without shareholder approval. Shareholder
          approval means approval by the lesser of (i) more than 50% of the
          outstanding voting securities of the Trust (or the Portfolio or class
          of shares if a matter affects just the Portfolio or class of shares),
          or (ii) 67% or more of the voting securities present at a meeting if
          the holders of more than 50% of the outstanding voting securities of
          the Trust (or the Portfolio or class of shares) are present or
          represented by proxy.

          As used in the restrictions set forth below and as used elsewhere in
          this SAI, the term "U.S. Government Securities" shall have the meaning
          set forth in the Investment Company Act of 1940, as amended (the "1940
          Act"). The 1940 Act defines U.S. Government Securities as securities
          issued or guaranteed by the United States government, its agencies or
          instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized and municipal securities escrowed
          with or refunded with escrowed U.S. government securities.

          The Portfolio has adopted the following fundamental policies:

          (1) With respect to 75% of its assets, the Portfolio may not purchase
          a security other than a U.S. Government Security, if, as a result,
          more than 5% of its total assets would be invested in the securities
          of a single issuer or the Portfolio would own more than 10% of the
          outstanding voting securities of any single issuer. (As noted in the
          Prospectus, the Portfolio is currently subject to the greater
          diversification standards of Rule 2a-7, which are not fundamental.)

          (2) The Portfolio may not purchase securities if 25% or more of the
          value of its total assets would be invested in the securities of
          issuers conducting their principal business activities in the same
          industry; provided that: (i) there is no limit on investments in U.S.
          Government Securities or in obligations of domestic commercial banks
          (including U.S. branches of foreign banks subject to regulations under
          U.S. laws applicable to domestic banks and, to the extent that its
          parent is unconditionally liable for the obligation, foreign branches
          of U.S. banks); (ii) this limitation shall not apply to the
          Portfolio's investments in municipal securities; (iii) there is no
          limit on investment in issuers domiciled in a single country; (iv)
          financial service companies are classified according to the end users
          of their services (for example, automobile finance, bank finance and
          diversified finance are each considered to be a separate industry);
          and (v) utility companies are classified according to their services
          (for example, gas, gas transmission, electric, and telephone are each
          considered to be a separate industry).

          (3) The Portfolio may not act as an underwriter of securities issued
          by others, except to the extent that it may be deemed an underwriter
          in connection with the disposition of its portfolio securities.

          (4) The Portfolio may not lend any security or make any other loan if,
          as a result, more than 25% of its total assets would be lent to other
          parties (but this limitation does not apply to purchases of commercial
          paper, debt securities or repurchase agreements).

          (5) The Portfolio may not purchase or sell real estate or any interest
          therein, except that the Portfolio may invest in debt obligations
          secured by real estate or interests therein or securities issued by
          companies that invest in real estate or interests therein.

          (6) The Portfolio may borrow money for temporary or emergency purposes
          (not for leveraging) in an amount not exceeding 25% of the value of
          its total assets (including the amount borrowed) less liabilities
          (other than borrowings). If borrowings exceed 25% of the value of the
          Portfolio's total assets by reason of a decline in net assets, it will
          reduce its borrowings within three business days to the extent
          necessary to comply with the 25% limitation. Reverse repurchase
          agreements or the segregation of assets in connection with such
          agreements shall not be considered borrowing for the purposes of this
          limit.

<PAGE>

          (7) The Portfolio may, notwithstanding any other investment policy or
          restriction (whether or not fundamental), invest all of its assets in
          the securities of a single open-end management investment company with
          substantially the same fundamental investment objectives, policies and
          restrictions as the Portfolio.

          Investment restriction (1) is intended to reflect the requirements
          under Section 5(b)(1) of the 1940 Act for a diversified fund. Rule
          2a-7 provides that money market funds that comply with the
          diversification limits of Rule 2a-7 are deemed to comply with the
          diversification limits of Section 5(b)(1). Thus, the Portfolio
          interprets restriction (1) in accordance with Rule 2a-7. Accordingly,
          if securities are subject to a guarantee provided by a non-controlled
          person, the Rule 2a-7 diversification tests apply to the guarantor,
          and the diversification test in restriction (1) does not apply to the
          issuer.

          The Portfolio has adopted the following nonfundamental investment
          restrictions that may be changed by the Trustees without shareholder
          approval:

          (1) The Portfolio may not invest in securities or enter into
          repurchase agreements with respect to any securities if, as a result,
          more than 10% of its net assets would be invested in repurchase
          agreements not entitling the holder to payment of principal within
          seven days and in other securities that are not readily marketable
          ("illiquid securities"). The Trustees, or the Portfolio's investment
          adviser acting pursuant to authority delegated by the Trustees, may
          determine that a readily available market exists for certain
          securities such as securities eligible for resale pursuant to Rule
          144A under the Securities Act of 1933, or any successor to such rule,
          Section 4(2) commercial paper and municipal lease obligations.
          Accordingly, such securities may not be subject to the foregoing
          limitation.

          (2) The Portfolio may not purchase securities on margin, or make short
          sales of securities, except for short sales against the box and the
          use of short-term credit necessary for the clearance of purchases and
          sales of portfolio securities.

          (3) The Portfolio may not pledge, mortgage, hypothecate or encumber
          any of its assets except to secure permitted borrowings or in
          connection with permitted short sales.

          (4) The Portfolio may not invest in companies for the purpose of
          exercising control of management.

          Under the terms of an exemptive order received from the Securities and
          Exchange Commission ("SEC"), the Portfolio may borrow money from or
          lend money to other funds that permit such transactions and for which
          Janus Capital serves as investment adviser. All such borrowing and
          lending will be subject to the above limits. The Portfolio will borrow
          money through the program only when the costs are equal to or lower
          than the cost of bank loans. Interfund loans and borrowings normally
          extend overnight, but can have a maximum duration of seven days. The
          Portfolio will lend through the program only when the returns are
          higher than those available from other short-term instruments (such as
          repurchase agreements). The Portfolio may have to borrow from a bank
          at a higher interest rate if an interfund loan is called or not
          renewed. Any delay in repayment to a lending Portfolio could result in
          a lost investment opportunity or additional borrowing costs.

          For purposes of the Portfolio's policies on investing in particular
          industries, the Portfolio will rely primarily on industry or industry
          group classifications as published by Bloomberg L.P. To the extent
          that Bloomberg L.P. industry classifications are so broad that the
          primary economic characteristics in a single industry are materially
          different, the Portfolio may further classify issuers in accordance
          with industry classifications as published by the SEC.

                                                                               3

INVESTMENT STRATEGIES

          The Portfolio may invest only in "eligible securities" as defined in
          Rule 2a-7 adopted under the 1940 Act. Generally, an eligible security
          is a security that (i) is denominated in U.S. dollars and has a
          remaining maturity of 397 days or less (as calculated pursuant to Rule
          2a-7); (ii) is rated, or is issued by an issuer with short-term debt
          outstanding that is rated, in one of the two highest rating categories
          by any two nationally recognized statistical rating organizations
          ("NRSROs") or, if only one NRSRO has issued a rating, by that NRSRO
          (the "Requisite NRSROs") or is unrated and of comparable quality to a
          rated security, as determined by Janus Capital; and (iii) has been
          determined by Janus Capital to present minimal credit risks pursuant
          to procedures approved by the Trustees. In addition, the Portfolio
          will maintain a dollar-weighted average portfolio maturity of 90 days
          or less. A description of the ratings of some NRSROs appears in
          Appendix A.

          Under Rule 2a-7, the Portfolio may not invest more than five percent
          of its total assets in the securities of any one issuer other than
          U.S. Government Securities, provided that in certain cases it may
          invest more than 5% of its assets in a single issuer for a period of
          up to three business days. Investment in demand features, guarantees
          and other types of instruments or features are subject to the
          diversification limits under Rule 2a-7.

          Pursuant to Rule 2a-7, the Portfolio will invest at least 95% of its
          total assets in "first-tier" securities. First-tier securities are
          eligible securities that are rated, or are issued by an issuer with
          short-term debt outstanding that is rated, in the highest rating
          category by the Requisite NRSROs or are unrated and of comparable
          quality to a rated security. In addition, the Portfolio may invest in
          "second-tier" securities which are eligible securities that are not
          first-tier securities. However, the Portfolio may not invest in a
          second-tier security if immediately after the acquisition thereof it
          would have invested more than (i) the greater of one percent of its
          total assets or one million dollars in second-tier securities issued
          by that issuer, or (ii) five percent of its total assets in
          second-tier securities.

          The following discussion of types of securities in which the Portfolio
          may invest supplements and should be read in conjunction with the
          Prospectus.

Participation Interests

          The Portfolio may purchase participation interests in loans or
          securities in which it may invest directly. Participation interests
          are generally sponsored or issued by banks or other financial
          institutions. A participation interest gives the Portfolio an
          undivided interest in the underlying loans or securities in the
          proportion that the Portfolio's interest bears to the total principal
          amount of the underlying loans or securities. Participation interests,
          which may have fixed, floating or variable rates, may carry a demand
          feature backed by a letter of credit or guarantee of a bank or
          institution permitting the holder to tender them back to the bank or
          other institution. For certain participation interests, the Portfolio
          will have the right to demand payment, on not more than seven days'
          notice, for all or a part of the Portfolio's participation interest.
          The Portfolio intends to exercise any demand rights it may have upon
          default under the terms of the loan or security, to provide liquidity
          or to maintain or improve the quality of the Portfolio's investment
          portfolio. The Portfolio will only purchase participation interests
          that Janus Capital determines present minimal credit risks.

Variable and Floating Rate Notes

          The Portfolio also may purchase variable and floating rate demand
          notes of corporations, which are unsecured obligations redeemable upon
          not more than 30 days' notice. These obligations include master demand
          notes that permit investment of fluctuating amounts at varying rates
          of interest pursuant to direct

 4
<PAGE>

          arrangements with the issuer of the instrument. The issuer of these
          obligations often has the right, after a given period, to prepay the
          outstanding principal amount of the obligations upon a specified
          number of days' notice. These obligations generally are not traded,
          nor generally is there an established secondary market for these
          obligations. To the extent a demand note does not have a seven day or
          shorter demand feature and there is no readily available market for
          the obligation, it is treated as an illiquid investment.

          Securities with ultimate maturities of greater than 397 days may be
          purchased only pursuant to Rule 2a-7. Under that Rule, only those
          long-term instruments that have demand features which comply with
          certain requirements and certain variable rate U.S. Government
          Securities may be purchased. The rate of interest on securities
          purchased by the Portfolio may be tied to short-term Treasury or other
          government securities or indices on securities that are permissible
          investments of the Portfolio, as well as other money market rates of
          interest. The Portfolio will not purchase securities whose values are
          tied to interest rates or indices that are not appropriate for the
          duration and volatility standards of a money market fund.

Mortgage- and Asset-Backed Securities

          The Portfolio may invest in mortgage-backed securities, which
          represent an interest in a pool of mortgages made by lenders such as
          commercial banks, savings and loan institutions, mortgage bankers,
          mortgage brokers and savings banks. Mortgage-backed securities may be
          issued by governmental or government-related entities or by
          non-governmental entities such as banks, savings and loan
          institutions, private mortgage insurance companies, mortgage bankers
          and other secondary market issuers.

          Interests in pools of mortgage-backed securities differ from other
          forms of debt securities which normally provide for periodic payment
          of interest in fixed amounts with principal payments at maturity or
          specified call dates. In contrast, mortgage-backed securities provide
          periodic payments which consist of interest and, in most cases,
          principal. In effect, these payments are a "pass-through" of the
          periodic payments and optional prepayments made by the individual
          borrowers on their mortgage loans, net of any fees paid to the issuer
          or guarantor of such securities. Additional payments to holders of
          mortgage-backed securities are caused by prepayments resulting from
          the sale of the underlying residential property, refinancing or
          foreclosure, net of fees or costs which may be incurred.

          As prepayment rates of individual pools of mortgage loans vary widely,
          it is not possible to predict accurately the average life of a
          particular security. Although mortgage-backed securities are issued
          with stated maturities of up to forty years, unscheduled or early
          payments of principal and interest on the underlying mortgages may
          shorten considerably the effective maturities. Mortgage-backed
          securities may have varying assumptions for average life. The volume
          of prepayments of principal on a pool of mortgages underlying a
          particular security will influence the yield of that security, and the
          principal returned to the Portfolio may be reinvested in instruments
          whose yield may be higher or lower than that which might have been
          obtained had the prepayments not occurred. When interest rates are
          declining, prepayments usually increase, with the result that
          reinvestment of principal prepayments will be at a lower rate than the
          rate applicable to the original mortgage-backed security.

          The Portfolio may invest in mortgage-backed securities that are issued
          by agencies or instrumentalities of the U.S. government. The
          Government National Mortgage Association ("GNMA") is the principal
          federal government guarantor of mortgage-backed securities. GNMA is a
          wholly-owned U.S. government corporation within the Department of
          Housing and Urban Development. GNMA Certificates are debt securities
          which represent an interest in one mortgage or a pool of mortgages
          which are insured by the Federal Housing Administration or the Farmers
          Home Administration or are guaranteed by the Veterans Administration.
          The Portfolio may also invest in pools of conventional mortgages which
          are issued or

                                                                               5
<PAGE>

          guaranteed by agencies of the U.S. government. GNMA pass-through
          securities are considered to be riskless with respect to default in
          that (i) the underlying mortgage loan portfolio is comprised entirely
          of government-backed loans and (ii) the timely payment of both
          principal and interest on the securities is guaranteed by the full
          faith and credit of the U.S. government, regardless of whether or not
          payments have been made on the underlying mortgages. GNMA pass-through
          securities are, however, subject to the same market risk as comparable
          debt securities. Therefore, the market value of the Portfolio's GNMA
          securities can be expected to fluctuate in response to changes in
          prevailing interest rate levels.

          Residential mortgage loans are pooled also by the Federal Home Loan
          Mortgage Corporation ("FHLMC"). FHLMC is a privately managed, publicly
          chartered agency created by Congress in 1970 for the purpose of
          increasing the availability of mortgage credit for residential
          housing. FHLMC issues participation certificates ("PCs") which
          represent interests in mortgages from FHLMC's national portfolio. The
          mortgage loans in FHLMC's portfolio are not U.S. government backed;
          rather, the loans are either uninsured with loan-to-value ratios of
          80% or less, or privately insured if the loan-to-value ratio exceeds
          80%. FHLMC guarantees the timely payment of interest and ultimate
          collection of principal on FHLMC PCs; the U.S. government does not
          guarantee any aspect of FHLMC PCs.

          The Federal National Mortgage Association ("FNMA") is a
          government-sponsored corporation owned entirely by private
          shareholders. It is subject to general regulation by the Secretary of
          Housing and Urban Development. FNMA purchases residential mortgages
          from a list of approved seller/servicers which include savings and
          loan associations, savings banks, commercial banks, credit unions and
          mortgage bankers. FNMA guarantees the timely payment of principal and
          interest on the pass-through securities issued by FNMA; the U.S.
          government does not guarantee any aspect of the FNMA pass-through
          securities.

          The Portfolio may also invest in privately-issued mortgage-backed
          securities to the extent permitted by their investment restrictions.
          Mortgage-backed securities offered by private issuers include
          pass-through securities comprised of pools of conventional residential
          mortgage loans; mortgage-backed bonds which are considered to be debt
          obligations of the institution issuing the bonds and which are
          collateralized by mortgage loans; and collateralized mortgage
          obligations ("CMOs") which are collateralized by mortgage-backed
          securities issued by GNMA, FHLMC or FNMA or by pools of conventional
          mortgages.

          Asset-backed securities represent direct or indirect participation in,
          or are secured by and payable from, assets other than mortgage-backed
          assets such as motor vehicle installment sales contracts, installment
          loan contracts, leases of various types of real and personal property
          and receivables from revolving credit agreements (credit cards).
          Asset-backed securities have yield characteristics similar to those of
          mortgage-backed securities and, accordingly, are subject to many of
          the same risks.

Reverse Repurchase Agreements

          Reverse repurchase agreements are transactions in which the Portfolio
          sells a security and simultaneously commits to repurchase that
          security from the buyer at an agreed upon price on an agreed upon
          future date. The resale price in a reverse repurchase agreement
          reflects a market rate of interest that is not related to the coupon
          rate or maturity of the sold security. For certain demand agreements,
          there is no agreed upon repurchase date and interest payments are
          calculated daily, often based upon the prevailing overnight repurchase
          rate. The Portfolio will use the proceeds of reverse repurchase
          agreements only to satisfy unusually heavy redemption requests or for
          other temporary or emergency purposes without the necessity of selling
          portfolio securities.

          Generally, a reverse repurchase agreement enables the Portfolio to
          recover for the term of the reverse repurchase agreement all or most
          of the cash invested in the portfolio securities sold and to keep the

 6
<PAGE>

          interest income associated with those portfolio securities. Such
          transactions are only advantageous if the interest cost to the
          Portfolio of the reverse repurchase transaction is less than the cost
          of obtaining the cash otherwise. In addition, interest costs on the
          money received in a reverse repurchase agreement may exceed the return
          received on the investments made by the Portfolio with those monies.

When Issued and Delayed Delivery Securities

          The Portfolio may purchase securities on a when-issued or delayed
          delivery basis. The Portfolio will enter into such transactions only
          when it has the intention of actually acquiring the securities. To
          facilitate such acquisitions, the Portfolio's custodian will segregate
          cash or high quality liquid assets in an amount at least equal to such
          commitments. On delivery dates for such transactions, the Portfolio
          will meet its obligations from maturities, sales of the segregated
          securities or from other available sources of cash. If it chooses to
          dispose of the right to acquire a when-issued security prior to its
          acquisition, the Portfolio could, as with the disposition of any other
          portfolio obligation, incur a gain or loss due to market fluctuation.
          At the time it makes the commitment to purchase securities on a
          when-issued or delayed delivery basis, the Portfolio will record the
          transaction as a purchase and thereafter reflect the value of such
          securities in determining its net asset value.

Investment Company Securities

          From time to time, the Portfolio may invest in securities of other
          investment companies. The Portfolio is subject to the provisions of
          Section 12(d)(1) of the 1940 Act. The Portfolio may invest in
          securities of money market funds managed by Janus Capital in excess of
          the limitations of Section 12(d)(1) under the terms of an SEC
          exemptive order obtained by Janus Capital and the Janus Funds.

Debt Obligations


          Money Market Portfolio may invest in U.S. dollar denominated debt
          obligations. In general, sales of these securities may not be made
          absent registration under the Securities Act of 1933 or the
          availability of an appropriate exemption. Pursuant to Section 4(2) of
          the 1933 Act or Rule 144A adopted under the 1933 Act, however, some of
          these securities are eligible for resale to institutional investors,
          and accordingly, Janus Capital may determine that a liquid market
          exists for such a security pursuant to guidelines adopted by the
          Trustees.


Obligations of Financial Institutions

          The Portfolio may invest in obligations of financial institutions.
          Examples of obligations in which the Portfolio may invest include
          negotiable certificates of deposit, bankers' acceptances, time
          deposits and other obligations of U.S. banks (including savings and
          loan associations) having total assets in excess of one billion
          dollars and U.S. branches of foreign banks having total assets in
          excess of ten billion dollars. The Portfolio may also invest in
          Eurodollar and Yankee bank obligations as discussed below and other
          U.S. dollar-denominated obligations of foreign banks having total
          assets in excess of ten billion dollars that Janus Capital believes
          are of an investment quality comparable to obligations of U.S. banks
          in which the Portfolio may invest.

          Certificates of deposit represent an institution's obligation to repay
          funds deposited with it that earn a specified interest rate over a
          given period. Bankers' acceptances are negotiable obligations of a
          bank to pay a draft which has been drawn by a customer and are usually
          backed by goods in international trade. Time deposits are
          non-negotiable deposits with a banking institution that earn a
          specified interest rate over a given period. Fixed time deposits,
          which are payable at a stated maturity date and bear a fixed rate of
          interest, generally may be withdrawn on demand by the Portfolio but
          may be subject to early withdrawal

                                                                               7

          penalties and that could reduce the Portfolio's yield. Unless there is
          a readily available market for them, time deposits that are subject to
          early withdrawal penalties and that mature in more than seven days
          will be treated as illiquid securities.

          Eurodollar bank obligations are dollar-denominated certificates of
          deposit or time deposits issued outside the U.S. capital markets by
          foreign branches of U.S. banks and by foreign banks. Yankee bank
          obligations are dollar-denominated obligations issued in the U.S.
          capital markets by foreign banks.

          Foreign, Eurodollar (and to a limited extent, Yankee) bank obligations
          are subject to certain sovereign risks. One such risk is the
          possibility that a foreign government might prevent dollar-denominated
          funds from flowing across its borders. Other risks include: adverse
          political and economic developments in a foreign country; the extent
          and quality of government regulation of financial markets and
          institutions; the imposition of foreign withholding taxes; and
          exploration or nationalization of foreign issuers.

U.S. Government Securities

          Money Market Portfolio may invest in U.S. Government Securities. U.S.
          Government Securities shall have the meaning set forth in the 1940
          Act. The 1940 Act defines U.S. Government Securities to include
          securities issued or guaranteed by the U.S. Government, its agencies
          and instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized by and municipal securities
          escrowed with or refunded with U.S. government securities. U.S.
          Government Securities in which the Portfolio may invest include U.S.
          Treasury securities and obligations issued or guaranteed by U.S.
          government agencies and instrumentalities that are backed by the full
          faith and credit of the U.S. government, such as those guaranteed by
          the Small Business Administration or issued by the Government National
          Mortgage Association. In addition, U.S. Government Securities in which
          the Portfolio may invest include securities supported primarily or
          solely by the creditworthiness of the issuer, such as securities of
          the Federal National Mortgage Association, the Federal Home Loan
          Mortgage Corporation and the Tennessee Valley Authority. There is no
          guarantee that the U.S. government will support securities not backed
          by its full faith and credit. Accordingly, although these securities
          have historically involved little risk of loss of principal if held to
          maturity, they may involve more risk than securities backed by the
          full faith and credit of the U.S. government.

Municipal Leases

          The Portfolio may invest in municipal leases. Municipal leases
          frequently have special risks not normally associated with general
          obligation or revenue bonds. Municipal leases are municipal securities
          which may take the form of a lease or an installment purchase or
          conditional sales contract. Municipal leases are issued by state and
          local governments and authorities to acquire a wide variety of
          equipment and facilities. Leases and installment purchase or
          conditional sale contracts (which normally provide for title to the
          leased asset to pass eventually to the government issuer) have evolved
          as a means for governmental issuers to acquire property and equipment
          without meeting the constitutional and statutory requirements for the
          issuance of debt. The debt-issuance limitations of many state
          constitutions and statutes are deemed to be inapplicable because of
          the inclusion in many leases or contracts of "non-appropriation"
          clauses that provide that the governmental issuer has no obligation to
          make future payments under the lease or contract unless money is
          appropriated for such purpose by the appropriate legislative body on a
          yearly or other periodic basis. The Portfolio will only purchase
          municipal leases subject to a non-appropriation clause when the
          payment of principal and accrued interest is backed by an
          unconditional irrevocable letter of credit, or guarantee of a bank or
          other entity that meets the criteria described in the Prospectus under
          "Taxable Investments."

<PAGE>

          In evaluating municipal lease obligations, Janus Capital will consider
          such factors as it deems appropriate, including: (a) whether the lease
          can be canceled; (b) the ability of the lease obligee to direct the
          sale of the underlying assets; (c) the general creditworthiness of the
          lease obligor; (d) the likelihood that the municipality will
          discontinue appropriating funding for the leased property in the event
          such property is no longer considered essential by the municipality;
          (e) the legal recourse of the lease obligee in the event of such a
          failure to appropriate funding; (f) whether the security is backed by
          a credit enhancement such as insurance; and (g) any limitations which
          are imposed on the lease obligor's ability to utilize substitute
          property or services other than those covered by the lease obligation.
          If a lease is backed by an unconditional letter of credit or other
          unconditional credit enhancement, then Janus Capital may determine
          that a lease is an eligible security solely on the basis of its
          evaluation of the credit enhancement.

          Municipal leases, like other municipal debt obligations, are subject
          to the risk of non-payment. The ability of issuers of municipal leases
          to make timely lease payments may be adversely impacted in general
          economic downturns and as relative governmental cost burdens are
          allocated and reallocated among federal, state and local governmental
          units. Such non-payment would result in a reduction of income to the
          Portfolio, and could result in a reduction in the value of the
          municipal lease experiencing non-payment and a potential decrease in
          the net asset value of the Portfolio.

                                                                               9

Performance data

          The Portfolio may provide current annualized and effective annualized
          yield quotations of the Shares based on the Shares' daily dividends.
          These quotations may from time to time be used in advertisements,
          shareholder reports or other communications to shareholders. All
          performance information supplied by the Portfolio in advertising is
          historical and is not intended to indicate future returns.

          In performance advertising, the Portfolio may compare any of its
          performance information with data published by independent evaluators
          such as Morningstar, Inc., Lipper Analytical Services, Inc., or
          CDC/Wiesenberger, Donoghue's Money Fund Report or other companies
          which track the investment performance of investment companies ("Fund
          Tracking Companies"). The Portfolio may also compare its performance
          information with the performance of recognized stock, bond and other
          indices, including but not limited to the Municipal Bond Buyers
          Indices, the Salomon Brothers Bond Index, the Lehman Brothers Bond
          Index, the Standard & Poor's 500 Composite Stock Price Index, the Dow
          Jones Industrial Average, U.S. Treasury bonds, bills or notes and
          changes in the Consumer Price Index as published by the U.S.
          Department of Commerce. The Portfolio may refer to general market
          performance over past time periods such as those published by Ibbotson
          Associates (for instance, its "Stocks, Bonds, Bills and Inflation
          Yearbook"). The Portfolio may also refer in such materials to mutual
          fund performance rankings and other data published by Fund Tracking
          Companies. Performance advertising may also refer to discussions of
          the Portfolio and comparative mutual fund data and ratings reported in
          independent periodicals, such as newspapers and financial magazines.

          Any current yield quotation of the Portfolio's Shares which is used in
          such a manner as to be subject to the provisions of Rule 482(d) under
          the Securities Act of 1933, as amended, shall consist of an annualized
          historical yield, carried at least to the nearest hundredth of one
          percent, based on a specific seven calendar day period. The current
          yield of the Portfolio's Shares shall be calculated by (a) determining
          the net change during a seven calendar day period in the value of a
          hypothetical account having a balance of one share at the beginning of
          the period, (b) dividing the net change by the value of the account at
          the beginning of the period to obtain a base period return, and (c)
          multiplying the quotient by 365/7 (i.e., annualizing). For this
          purpose, the net change in account value will reflect the value of
          additional shares purchased with dividends declared on the original
          share and dividends declared on both the original share and any such
          additional shares, but will not reflect any realized gains or losses
          from the sale of securities or any unrealized appreciation or
          depreciation on portfolio securities. In addition, the Portfolio may
          advertise effective yield quotations. Effective yield quotations are
          calculated by adding 1 to the base period return, raising the sum to a
          power equal to 365/7, and subtracting 1 from the result (i.e.,
          compounding).

          Income calculated for the purpose of determining the yield of the
          Portfolio's Shares differs from income as determined for other
          accounting purposes. Because of the different accounting methods used,
          and because of the compounding assumed in yield calculations, the
          yield quoted for the Portfolio's Shares may differ from the rate of
          distribution the Shares paid over the same period or the rate of
          income reported in the Portfolio's financial statements.

<PAGE>

          Although published yield information is useful to investors in
          reviewing the performance of the Portfolio's Shares, investors should
          be aware that the yield fluctuates from day to day and that the
          Share's yield for any given period is not an indication or
          representation by the Portfolio of future yields or rates of return on
          the Portfolio's Shares. The Shares' yield is not fixed or guaranteed,
          and an investment in the Portfolio is not insured. Accordingly, the
          Shares' yield information may not necessarily be used to compare
          Portfolio Shares with investment alternatives which, like money market
          instruments or bank accounts, may provide a fixed rate of interest. In
          addition, because investments in the Portfolio are not insured or
          guaranteed, the yield information may not necessarily be used to
          compare the Portfolio with investment alternatives which are insured
          or guaranteed.


          The Shares' current yield and effective yield for the seven day period
          ended December 31, 1999, were 5.20% and 5.33%, respectively.


                                                                              11

Determination of net asset value

          Pursuant to the rules of the SEC, the Trustees have established
          procedures to stabilize the Portfolio's net asset value at $1.00 per
          Share. These procedures include a review of the extent of any
          deviation of net asset value per Share as a result of fluctuating
          interest rates, based on available market rates, from the Portfolio's
          $1.00 amortized cost price per Share. Should that deviation exceed
          1/2 of 1%, the Trustees will consider whether any action should be
          initiated to eliminate or reduce material dilution or other unfair
          results to shareholders. Such action may include redemption of shares
          in kind, selling portfolio securities prior to maturity, reducing or
          withholding dividends and utilizing a net asset value per share as
          determined by using available market quotations. The Portfolio i) will
          maintain a dollar-weighted average portfolio maturity of 90 days or
          less; ii) will not purchase any instrument with a remaining maturity
          greater than 397 days or subject to a repurchase agreement having a
          duration of greater than 397 days; iii) will limit portfolio
          investments, including repurchase agreements, to those U.S.
          dollar-denominated instruments that Janus Capital has determined
          present minimal credit risks pursuant to procedures established by the
          Trustees; and iv) will comply with certain reporting and recordkeeping
          procedures. The Trust has also established procedures to ensure that
          portfolio securities meet the Portfolio's high quality criteria.

Investment adviser

          As stated in the Prospectus, the Portfolio has an Investment Advisory
          Agreement with Janus Capital, 100 Fillmore Street, Denver, Colorado
          80206-4928. The Advisory Agreement provides that Janus Capital will
          furnish continuous advice and recommendations concerning the
          Portfolio's investments, provide office space for the Portfolio and
          pay the salaries, fees and expenses of all Portfolio officers and of
          those Trustees who are affiliated with Janus Capital. Janus Capital
          also may make payments to selected broker-dealer firms or institutions
          which were instrumental in the acquisition of shareholders for the
          Portfolio or which performed services with respect to shareholder
          accounts. The minimum aggregate size required for eligibility for such
          payments, and the factors in selecting the broker-dealer firms and
          institutions to which they will be made, are determined from time to
          time by Janus Capital. Janus Capital is also authorized to perform the
          management and administrative services necessary for the operation of
          the Portfolio.

          The Portfolio pays custodian agent fees and expenses, brokerage
          commissions and dealer spreads and other expenses in connection with
          the execution of Portfolio transactions, legal and accounting
          expenses, interest and taxes, registration fees, expenses of
          shareholders' meetings, and reports to shareholders, fees and expenses
          of Trustees who are not affiliated with Janus Capital, and other costs
          of complying with applicable laws regulating the sale of Portfolio
          shares. Pursuant to the Advisory Agreement, Janus Capital furnishes
          certain other services, including net asset value determination,
          portfolio accounting and record keeping for which the Portfolio may
          reimburse Janus Capital for its costs.

          The Portfolio has agreed to compensate Janus Capital for its advisory
          services by the monthly payment of an advisory fee at the annual rate
          of .25% of the Portfolio's average daily net assets. Janus Capital has
          agreed to reimburse the Portfolio by the amount, if any, that the
          Portfolio's normal operating expenses in any fiscal year, including
          the investment advisory fee but excluding the distribution fee and
          participant administration fee described below, brokerage commissions,
          interest, taxes and extraordinary expenses, exceed .50% of average
          daily net assets. Janus Capital has agreed to continue such waivers
          until at least the next annual renewal of the advisory agreements.


          For the fiscal year ended December 31, 1999, the advisory fee was
          $137,596. For the fiscal year ended December 31, 1998 and December 31,
          1997, the advisory fees were $79,201 and $22,333, respectively. For
          the fiscal year ended December 31, 1997, Janus Capital waived $2,184.



          The Advisory Agreement is dated July 1, 1997 and will continue in
          effect until July 1, 2001, and thereafter from year to year so long as
          such continuance is approved annually by a majority of the Portfolio's
          Trustees who are not parties to the Advisory Agreement or interested
          persons of any such party, and by either a majority of the outstanding
          voting shares or the Trustees. The Advisory Agreement i) may be
          terminated without the payment of any penalty by the Portfolio or
          Janus Capital on 60 days' written notice; ii) terminates automatically
          in the event of its assignment; and iii) generally, may not be amended
          without the approval by vote of a majority of the Trustees, including
          the Trustees who are not interested persons of the Portfolio or Janus
          Capital and, to the extent required by the 1940 Act, the vote of a
          majority of the outstanding voting securities of the Portfolio.


          Janus Capital also acts as sub-advisor for a number of private-label
          mutual funds and provides separate account advisory services for
          institutional accounts. Investment decisions for each account managed
          by Janus Capital, including the Portfolio, are made independently from
          those for any other account that is or may in the future become
          managed by Janus Capital or its affiliates. If, however, a number of
          accounts managed by Janus Capital are contemporaneously engaged in the
          purchase or sale of the same security, the orders may be aggregated
          and/or the transactions may be averaged as to price and allocated
          equitably to each account. In some cases, this policy might adversely
          affect the price paid or received by an account or the size of the
          position obtained or liquidated for an account. Pursuant to an
          exemptive order granted by

                                                                              13

          the SEC, the Portfolios and other funds advised by Janus Capital may
          also transfer daily uninvested cash balances into one or more joint
          trading accounts. Assets in the joint trading accounts are invested in
          money market instruments and the proceeds are allocated to the
          participating funds on a pro rata basis.


          Kansas City Southern Industries, Inc. ("KCSI"), indirectly through its
          wholly owned subsidiary, Stilwell Financial Inc., owns approximately
          81% of the outstanding voting stock of Janus Capital. KCSI is a
          publicly traded holding company whose primary subsidiaries are engaged
          in transportation, information processing and financial services.
          Thomas H. Bailey, President and Chairman of the Board of Janus
          Capital, owns approximately 12% of Janus Capital's voting stock and,
          by agreement with KCSI, selects at least a majority of Janus Capital's
          Board.



          KCSI has announced its intention to separate its transportation and
          financial services businesses. KCSI anticipates the separation to be
          completed in the first half of 2000.


          Each account managed by Janus Capital has its own investment objective
          and is managed in accordance with that objective by a particular
          portfolio manager or team of portfolio managers. As a result, from
          time to time two or more different managed accounts may pursue
          divergent investment strategies with respect to investments or
          categories of investments.


          Janus Capital does not permit portfolio managers to purchase and sell
          securities for their own accounts except under the limited exceptions
          contained in the Portfolio's Code of Ethics ("Code"). The Portfolio's
          Code of Ethics is on file with and available from the SEC through the
          SEC Web site at www.sec.gov. The Code applies to Directors/ Trustees
          of Janus Capital and the Portfolios and employees of Janus Capital and
          the Trust, and requires investment personnel and officers of Janus
          Capital, inside Directors/Trustees of Janus Capital and the Portfolio
          and certain other designated employees deemed to have access to
          current trading information to pre-clear all transactions in
          securities not otherwise exempt under the Code. Requests for trading
          authorization will be denied when, among other reasons, the proposed
          personal transaction would be contrary to the provisions of the Code
          or would be deemed to adversely affect any transaction then known to
          be under consideration for or to have been effected on behalf of any
          client account, including the Portfolio.



          In addition to the pre-clearance requirement described above, the Code
          subjects such personnel, to various trading restrictions and reporting
          obligations. All reportable transactions are required to be reviewed
          for compliance with the Code. Those persons also may be required under
          certain circumstances to forfeit their profits made from personal
          trading.



          The provisions of the Code are administered by and subject to
          exceptions authorized by Janus Capital.

Custodian, transfer agent and certain affiliations

          Citibank, N.A., 111 Wall Street, 24th Floor, Zone 5, New York, NY
          10043, is the Portfolio's custodian. The custodian holds the
          Portfolio's assets in safekeeping and collects and remits the income
          thereon, subject to the instructions of the Portfolio.

          Janus Service Corporation, P.O. Box 173375, Denver, Colorado
          80217-3375, a wholly-owned subsidiary of Janus Capital, is the
          Portfolio's transfer agent. In addition, Janus Service provides
          certain other administrative, recordkeeping and shareholder relations
          services to the Portfolio. Janus Service receives a participant
          administration fee at an annual rate of up to .25% of the average
          daily net assets of the Shares of the Portfolio for providing or
          procuring recordkeeping, subaccounting and other administrative
          services to plans and plan participants who invest in the Shares of
          the Portfolio. Janus Service expects to use substantially all of this
          fee to compensate qualified plan service providers for providing these
          services (at an annual rate of up to .25% of the average daily net
          assets of the Shares attributable to plan participants receiving
          services from each service provider). Services provided by qualified
          plan service providers may include but are not limited to participant
          recordkeeping, processing and aggregating purchase and redemption
          transactions, providing periodic statements, forwarding prospectuses,
          shareholder reports and other materials to existing plan participants,
          and other participant administrative services.


          For each of the fiscal years ended December 31, 1998 and December 31,
          1999, the Shares paid a de minimus amount in participant
          administration fees to qualified plan service providers including
          Janus Service. Participant administration fees earned by Janus Service
          are in connection with seed capital invested by Janus Capital in the
          Shares and have been rebated to Janus Capital.


          Janus Distributors, Inc. ("Janus Distributors"), 100 Fillmore Street,
          Denver, Colorado 80206-4928, a wholly-owned subsidiary of Janus
          Capital, is a distributor of the Portfolio. Janus Distributors is
          registered as a broker-dealer under the Securities Exchange Act of
          1934 (the "Exchange Act") and is a member of the National Association
          of Securities Dealers, Inc.


          The Portfolio pays DST Systems, Inc., a subsidiary of KCSI, license
          fees at the annual rate of $3.98 per shareholder account for the use
          of DST's shareholder accounting system. The Portfolio also pays DST
          $1.10 per closed shareholder account. The Portfolio pays DST for the
          use of its portfolio and fund accounting system a monthly base fee of
          $250 to $1,250 per month based on the number of Janus funds using the
          system and an asset charge of $1 per million dollars of net assets
          (not to exceed $500 per month).


          The Trustees have authorized the Portfolio to use another affiliate of
          DST as introducing broker for certain Portfolio transactions as a
          means to reduce Portfolio expenses through credits against the charges
          of DST and its affiliates with regard to commissions earned by such
          affiliate. See "Portfolio Transactions and Brokerage."

                                                                              15

Portfolio transactions and brokerage

          Decisions as to the assignment of portfolio business for the Portfolio
          and negotiation of its commission rates are made by Janus Capital
          whose policy is to obtain the "best execution" (prompt and reliable
          execution at the most favorable security price) of all portfolio
          transactions.

          In selecting brokers and dealers and in negotiating commissions, Janus
          Capital considers a number of factors, including but not limited to:
          Janus Capital's knowledge of currently available negotiated commission
          rates or prices of securities currently available and other current
          transaction costs; the nature of the security being traded; the size
          and type of the transaction; the nature and character of the markets
          for the security to be purchased or sold; the desired timing of the
          trade; the activity existing and expected in the market for the
          particular security; confidentiality; the quality of the execution,
          clearance and settlement services; financial stability of the broker
          or dealer; the existence of actual or apparent operational problems of
          any broker or dealer; and research products or services provided. In
          recognition of the value of the foregoing factors, Janus Capital may
          place portfolio transactions with a broker or dealer with whom it has
          negotiated a commission that is in excess of the commission another
          broker or dealer would have charged for effecting that transaction if
          Janus Capital determines in good faith that such amount of commission
          was reasonable in relation to the value of the brokerage and research
          provided by such broker or dealer viewed in terms of either that
          particular transaction or of the overall responsibilities of Janus
          Capital. These research and other services may include, but are not
          limited to, general economic and security market reviews, industry and
          company reviews, evaluations of securities, recommendations as to the
          purchase and sale of securities, and access to third party
          publications, computer and electronic equipment and software. Research
          received from brokers or dealers is supplemental to Janus Capital's
          own research efforts.


          For the fiscal years ended December 31, 1999, December 31, 1998 and
          December 31, 1997, the Portfolio did not incur any brokerage
          commissions. The Portfolio generally buys and sells securities in
          principal and agency transactions in which no commissions are paid.
          However, the Portfolio may engage an agent and pay commissions for
          such transactions if Janus Capital believes that the net result of the
          transaction to the Portfolio will be no less favorable than that of
          contemporaneously available principal transactions.


          Janus Capital may use research products and services in servicing
          other accounts in addition to the Portfolio. If Janus Capital
          determines that any research product or service has a mixed use, such
          that it also serves functions that do not assist in the investment
          decision-making process, Janus Capital may allocate the costs of such
          service or product accordingly. Only that portion of the product or
          service that Janus Capital determines will assist it in the investment
          decision-making process may be paid for in brokerage commission
          dollars. Such allocation may create a conflict of interest for Janus
          Capital.

          Janus Capital may consider sales of Portfolio shares or shares of
          other Janus funds by a broker-dealer or the recommendation of a
          broker-dealer to its customers that they purchase such shares as a
          factor in the selection of broker-dealers to execute Portfolio
          transactions. Janus Capital may also consider payments made by brokers
          effecting transactions for a Portfolio i) to the Portfolio or ii) to
          other persons on behalf of the Portfolio for services provided to the
          Portfolio for which it would be obligated to pay. In placing portfolio
          business with such broker-dealers, Janus Capital will seek the best
          execution of each transaction.

          When the Portfolio purchases or sells a security in the
          over-the-counter market, the transaction takes place directly with a
          principal market-maker, without the use of a broker, except in those
          circumstances where in the opinion of Janus Capital better prices and
          executions will be achieved through the use of a broker.

Purchase of Shares

          Shares of the Portfolio can be purchased only by qualified plans.
          Certain designated organizations are authorized to receive purchase
          orders on the Portfolio's behalf, and those organizations are
          authorized to designate their agents and affiliates as intermediaries
          to receive purchase orders. Purchase orders are deemed received by the
          Portfolio when authorized organizations, their agents or affiliates
          receive the order. The Portfolio is not responsible for the failure of
          any designated organization or its agents or affiliates to carry out
          its obligations to its customers. Shares of the Portfolio are
          purchased at the NAV per share as determined at the close of regular
          trading session of the New York Stock Exchange next occurring after a
          purchase order is received and accepted by the Portfolio or its
          authorized agent. In order to receive a day's dividend, your order
          must be received by the close of the regular trading session of the
          NYSE. Your plan documents contain detailed information about investing
          in the Portfolio.

                                                                              21

Distribution plan

          Under a distribution plan ("Plan") adopted in accordance with Rule
          12b-1 under the Investment Company Act of 1940 (the "1940 Act"), the
          Shares may pay Janus Distributors, Inc., the Trust's distributor, a
          fee at an annual rate of up to 0.25% of the average daily net assets
          of the Shares of the Portfolio. Under the terms of the Plan, the Trust
          is authorized to make payments to Janus Distributors for remittance to
          qualified plan service providers as compensation for distribution and
          shareholder servicing performed by such providers. The Plan is a
          compensation type plan and permits the payment at an annual rate of up
          to 0.25% of the average daily net assets of the Shares of the
          Portfolio for activities which are primarily intended to result in
          sales of the Shares, including but not limited to preparing, printing
          and distributing prospectuses, Statements of Additional Information,
          shareholder reports, and educational materials to prospective and
          existing plan participants; responding to inquiries by qualified plan
          participants; receiving and answering correspondence and similar
          activities. On December 10, 1996, Trustees unanimously approved the
          Plan which became effective May 1, 1997. The Plan and any Rule 12b-1
          related agreement that is entered into by the Portfolio or Janus
          Distributors in connection with the Plan will continue in effect for a
          period of more than one year only so long as continuance is
          specifically approved at least annually by a vote of a majority of the
          Trustees, and of a majority of the Trustees who are not interested
          persons (as defined in the 1940 Act) of the Trust and who have no
          direct or indirect financial interest in the operation of the Plan or
          any related agreements ("12b-1 Trustees"). All material amendments to
          the Plan must be approved by a majority vote of the Trustees,
          including a majority of the 12b-1 Trustees, at a meeting called for
          that purpose. In addition, the Plan may be terminated at any time,
          without penalty, by vote of a majority of the outstanding Shares of
          the Portfolio or by vote of a majority of 12b-1 Trustees.


          For the fiscal year ended December 31, 1999, the Shares of the
          Portfolio paid a de minimus amount in 12b-1 fees as compensation to
          broker-dealers and other service providers including Janus
          Distributors. Fees earned by Janus Distributors are in connection with
          seed capital invested by Janus Capital in the Shares and have been
          rebated to Janus Capital.

Redemption of Shares


          Redemptions, like purchases, may only be effected through qualified
          plans. Certain designated organizations are authorized to receive
          redemption orders on the Portfolio's behalf and those organizations
          are authorized to designate their agents and affiliates as
          intermediaries to receive redemption orders. Redemption orders are
          deemed received by the Portfolio when authorized organizations, their
          agents or affiliates receive the order. The Portfolio is not
          responsible for the failure of any designated organization or its
          agents or affiliates to carry out its obligations to its customers.
          Shares normally will be redeemed for cash, although the Portfolio
          retains the right to redeem some or all of its shares in kind under
          unusual circumstances, in order to protect the interests of remaining
          shareholders, or to accommodate a request by a particular shareholder
          that does not adversely affect the interest of the remaining
          shareholders by delivery of securities selected from its assets at its
          discretion. However, the Portfolio is governed by Rule 18f-1 under the
          1940 Act, which requires the Portfolio to redeem shares solely in cash
          up to the lesser of $250,000 or 1% of the net asset value of the
          Portfolio during any 90-day period for any one shareholder. Should
          redemptions by any shareholder exceed such limitation, their Portfolio
          will have the option of redeeming the excess in cash or in kind. If
          shares are redeemed in kind, the redeeming shareholder might incur
          brokerage costs in converting the assets to cash. The method of
          valuing securities used to make redemptions in kind will be the same
          as the method of valuing portfolio securities described under
          "Determination of Net Asset Value" and such valuation will be made as
          of the same time the redemption price is determined.


          The right to require the Portfolio to redeem its shares may be
          suspended, or the date of payment may be postponed, whenever (1)
          trading on the NYSE is restricted, as determined by the SEC, or the
          NYSE is closed except for holidays and weekends, (2) the SEC permits
          such suspension and so orders, or (3) an emergency exists as
          determined by the SEC so that disposal of securities or determination
          of NAV is not reasonably practicable.

                                                                              23

Dividends and tax status

          Dividends representing substantially all of the net investment income
          and any net realized gains on sales of securities are declared daily,
          Saturdays, Sundays and holidays included, and distributed on the last
          business day of each month. If a month begins on a Saturday, Sunday,
          or holiday, dividends for those days are declared at the end of the
          preceding month and distributed on the first business day of the
          month. The Portfolio intends to qualify as a regulated investment
          company by satisfying certain requirements prescribed by Subchapter M
          of the Code. In addition, because a class of shares of the Portfolio
          are sold in connection with variable insurance contracts, the
          Portfolio intends to comply with the diversification requirements of
          Internal Revenue Code Section 817(h) related to the tax-deferred
          status of insurance company separate accounts.

          All income dividends on the Portfolio's Shares are reinvested
          automatically in additional Shares of the Portfolio at the NAV
          determined on the first business day following the record date.

          Because Shares of the Portfolio can only be purchased through
          qualified plans, it is anticipated that any income dividends or
          capital gains distributions will be exempt from current taxation if
          left to accumulate within such plans. See the plan documents for
          additional information.

Principal shareholders


          The officers and Trustees of the Portfolio cannot directly own Shares
          of the Portfolio without purchasing through a participant directed
          qualified plan. As a result, such officers and Trustees as a group own
          less than 1% of the outstanding Shares of the Portfolio. As of April
          3, 2000, all of the outstanding Shares of the Portfolio were owned by
          qualified plans and by Janus Capital, which provided seed capital for
          the Portfolio. The percentage ownership of each qualified plan owning
          more than 5% of the Shares of the Portfolio is as follows:

Miscellaneous information


          The Portfolio is an open-end management investment company registered
          under the 1940 Act as a series of the Trust, which was organized as a
          Delaware business trust on May 20, 1993. The Trust Instrument permits
          the Trustees to issue an unlimited number of shares of beneficial
          interest from an unlimited number of series and classes of shares. As
          of the date of this SAI, the Trust consists of fourteen series of
          shares, known as "portfolios," in two or three classes. Additional
          series and/or classes may be created from time to time.


SHARES OF THE TRUST

          The Trust is authorized to issue an unlimited number of shares of
          beneficial interest with a par value of $0.001 per share for each
          series of the Trust. Shares of each series of the Trust are fully paid
          and nonassessable when issued. The Shares of the Portfolio participate
          equally in dividends and other distributions by the Portfolio, and in
          residual assets of the Portfolio in the event of liquidation. Shares
          of the Portfolio have no preemptive, conversion or subscription
          rights.


          The Portfolio currently offers two or three classes of shares. The
          Shares discussed in this SAI are offered only to qualified plans whose
          service providers require a fee from Trust assets for providing
          certain services to plan participants. A second class of shares,
          Institutional Shares, are offered only in connection with investment
          in and payments under variable contracts and life insurance contracts,
          as well as certain qualified retirement plans.


SHAREHOLDER MEETINGS

          The Trust does not intend to hold annual shareholder meetings.
          However, special meetings may be called for the Portfolio or for the
          Trust as a whole for purposes such as electing or removing Trustees,
          terminating or reorganizing the Trust, changing fundamental policies,
          or for any other purpose requiring a shareholder vote under the 1940
          Act. Separate votes are taken by each Portfolio or class only if a
          matter affects or requires the vote of only that Portfolio or class or
          that Portfolio's or class' interest in the matter differs from the
          interest of the other portfolios or class of the Trust. A shareholder
          is entitled to one vote for each Share owned.

VOTING RIGHTS

          The Trustees are responsible for major decisions relating to the
          Portfolio's policies and objectives; the Trustees oversee the
          operation of the Portfolio by its officers.

          The present Trustees were elected by the initial trustee of the Trust
          on May 25, 1993, and were approved by the initial shareholder on May
          25, 1993 with the exception of Mr. Craig and Mr. Rothe who were
          appointed by the Trustees as of June 30, 1995 and as of January 1,
          1997, respectively. Under the Trust Instrument, each Trustee will
          continue in office until the termination of the Trust or his earlier
          death, retirement, resignation, bankruptcy, incapacity or removal.
          Vacancies will be filled by a majority of the remaining Trustees,
          subject to the 1940 Act. Therefore, no annual or regular meetings of
          shareholders normally will be held, unless otherwise required by the
          Trust Instrument or the 1940 Act. Subject to the foregoing,
          shareholders have the power to vote to elect or remove Trustees, to
          terminate or reorganize the Portfolio, to amend the Trust Instrument,
          to bring certain derivative actions and on any other matters on which
          a shareholder vote is required by the 1940 Act, the Trust Instrument,
          the Trust's Bylaws or the Trustees.

          As mentioned in "Shareholder Meetings", each share of each portfolio
          of the Trust has one vote (and fractional votes for fractional
          shares). Shares of all portfolios of the Trust have noncumulative
          voting rights, which means that the holders of more than 50% of the
          shares of all portfolios of the Trust voting for the election of
          Trustees can elect 100% of the Trustees if they choose to do so and,
          in such event, the holders

 26
<PAGE>

          of the remaining shares will not be able to elect any Trustees. Each
          portfolio or class of the Trust will vote separately only with respect
          to those matters that affect only that portfolio or class or if an
          interest of a portfolio or class in the matter differs from the
          interests of other portfolios or classes of the Trust.

Appendix A

DESCRIPTION OF SECURITIES RATINGS

Moody's and Standard & Poor's

          MUNICIPAL AND CORPORATE BONDS AND MUNICIPAL LOANS

          The two highest ratings of Standard & Poor's Ratings Services ("S&P")
          for municipal and corporate bonds are AAA and AA. Bonds rated AAA have
          the highest rating assigned by S&P to a debt obligation. Capacity to
          pay interest and repay principal is extremely strong. Bonds rated AA
          have a very strong capacity to pay interest and repay principal and
          differ from the highest rated issues only in a small degree. The AA
          rating may be modified by the addition of a plus (+) or minus (-) sign
          to show relative standing within that rating category.

          The two highest ratings of Moody's Investors Service, Inc. ("Moody's")
          for municipal and corporate bonds are Aaa and Aa. Bonds rated Aaa are
          judged by Moody's to be of the best quality. Bonds rated Aa are judged
          to be of high quality by all standards. Together with the Aaa group,
          they comprise what are generally known as high-grade bonds. Moody's
          states that Aa bonds are rated lower than the best bonds because
          margins of protection or other elements make long-term risks appear
          somewhat larger than Aaa securities. The generic rating Aa may be
          modified by the addition of the numerals 1, 2 or 3. The modifier 1
          indicates that the security ranks in the higher end of the Aa rating
          category; the modifier 2 indicates a mid-range ranking; and the
          modifier 3 indicates that the issue ranks in the lower end of such
          rating category.

          SHORT TERM MUNICIPAL LOANS

          S&P's highest rating for short-term municipal loans is SP-1. S&P
          states that short-term municipal securities bearing the SP-1
          designation have a strong capacity to pay principal and interest.
          Those issues rated SP-1 which are determined to possess a very strong
          capacity to pay debt service will be given a plus (+) designation.
          Issues rated SP-2 have satisfactory capacity to pay principal and
          interest with some vulnerability to adverse financial and economic
          changes over the term of the notes.

          Moody's highest rating for short-term municipal loans is MIG-1/VMIG-1.
          Moody's states that short-term municipal securities rated MIG-1/VMIG-1
          are of the best quality, enjoying strong protection from established
          cash flows of funds for their servicing or from established and
          broad-based access to the market for refinancing, or both. Loans
          bearing the MIG-2/VMIG-2 designation are of high quality, with margins
          of protection ample although not so large as in the MIG-1/VMIG-1
          group.

          OTHER SHORT-TERM DEBT SECURITIES

          Prime-1 and Prime-2 are the two highest ratings assigned by Moody's
          for other short-term debt securities and commercial paper, and A-1 and
          A-2 are the two highest ratings for commercial paper assigned by S&P.
          Moody's uses the numbers 1, 2 and 3 to denote relative strength within
          its highest classification of Prime, while S&P uses the numbers 1, 2
          and 3 to denote relative strength within its highest classification of
          A. Issuers rated Prime-1 by Moody's have a superior ability for
          repayment of senior short-term debt obligations and have many of the
          following characteristics: leading market positions in
          well-established industries, high rates of return on funds employed,
          conservative capitalization structure with moderate reliance on debt
          and ample asset protection, broad margins in earnings coverage of
          fixed financial charges and high internal cash generation, and well
          established access to a range of financial markets and assured sources
          of alternate liquidity. Issuers rated Prime-2 by Moody's have a strong
          ability for repayment of senior short-term debt obligations and
          display many of the same characteristics displayed by issuers rated
          Prime-1, but to a lesser degree. Issuers rated A-1 by S&P carry a
          strong degree of safety regarding timely

                                                                              29
<PAGE>

          repayment. Those issues determined to possess extremely strong safety
          characteristics are denoted with a plus (+) designation. Issuers rated
          A-2 by S&P carry a satisfactory degree of safety regarding timely
          repayment.

                F-1......................... Very strong credit quality. Issues assigned this rating
                                             reflect an assurance for timely payment only slightly less
                                             in degree than issues rated F-1+.
                F-2......................... Good credit quality. Issues assigned this rating have a
                                             satisfactory degree of assurance for timely payments, but
                                             the margin of safety is not as great as the F-1+ and F-1
                                             ratings.

                                             strong and supported by good fundamental protection factors.
                                             Risk factors are very small.

                                             needs may enlarge total financing requirements, access to
                                             capital markets is good. Risk factors are small.

                                             more susceptible to adverse developments (both internal and
                                             external) than obligations with higher ratings, capacity to
                                             service principal and interest in a timely fashion is
                                             considered adequate.
                TBW-4....................... The lowest rating category; this rating is regarded as
                                             non-investment grade and therefore speculative.

Appendix B

DESCRIPTION OF MUNICIPAL SECURITIES

          MUNICIPAL NOTES generally are used to provide for short-term capital
          needs and usually have maturities of one year or less. They include
          the following:

          1. Project Notes, which carry a U.S. government guarantee, are issued
          by public bodies (called "local issuing agencies") created under the
          laws of a state, territory, or U.S. possession. They have maturities
          that range up to one year from the date of issuance. Project Notes are
          backed by an agreement between the local issuing agency and the
          Federal Department of Housing and Urban Development. These Notes
          provide financing for a wide range of financial assistance programs
          for housing, redevelopment, and related needs (such as low-income
          housing programs and renewal programs).

          2. Tax Anticipation Notes are issued to finance working capital needs
          of municipalities. Generally, they are issued in anticipation of
          various seasonal tax revenues, such as income, sales, use and business
          taxes, and are payable from these specific future taxes.

          3. Revenue Anticipation Notes are issued in expectation of receipt of
          other types of revenues, such as Federal revenues available under the
          Federal Revenue Sharing Programs.

          4. Bond Anticipation Notes are issued to provide interim financing
          until long-term financing can be arranged. In most cases, the
          long-term bonds then provide the money for the repayment of the Notes.

          5. Construction Loan Notes are sold to provide construction financing.
          After successful completion and acceptance, many projects receive
          permanent financing through the Federal Housing Administration under
          the Federal National Mortgage Association ("Fannie Mae") or the
          Government National Mortgage Association ("Ginnie Mae").

          6. Tax-Exempt Commercial Paper is a short-term obligation with a
          stated maturity of 365 days or less. It is issued by agencies of state
          and local governments to finance seasonal working capital needs or as
          short-term financing in anticipation of longer term financing.

          MUNICIPAL BONDS, which meet longer term capital needs and generally
          have maturities of more than one year when issued, have three
          principal classifications:

          1. General Obligation Bonds are issued by such entities as states,
          counties, cities, towns, and regional districts. The proceeds of these
          obligations are used to fund a wide range of public projects,
          including construction or improvement of schools, highways and roads,
          and water and sewer systems. The basic security behind General
          Obligation Bonds is the issuer's pledge of its full faith and credit
          and taxing power for the payment of principal and interest. The taxes
          that can be levied for the payment of debt service may be limited or
          unlimited as to the rate or amount of special assessments.

          2. Revenue Bonds in recent years have come to include an increasingly
          wide variety of types of municipal obligations. As with other kinds of
          municipal obligations, the issuers of revenue bonds may consist of
          virtually any form of state or local governmental entity, including
          states, state agencies, cities, counties, authorities of various
          kinds, such as public housing or redevelopment authorities, and
          special districts, such as water, sewer or sanitary districts.
          Generally, revenue bonds are secured by the revenues or net revenues
          derived from a particular facility, group of facilities, or, in some
          cases, the proceeds of a special excise or other specific revenue
          source. Revenue bonds are issued to finance a wide variety of capital
          projects including electric, gas, water and sewer systems; highways,
          bridges, and tunnels; port and airport facilities; colleges and
          universities; and hospitals. Many of these bonds provide additional
          security in the form of a debt service reserve fund to be used to make
          principal and interest payments. Various forms of credit enhancement,
          such as a bank letter of credit or municipal bond insurance, may also
          be employed in revenue bond issues. Housing authorities have a wide
          range of security, including partially or fully insured mortgages,
          rent subsidized and/or collateralized mortgages, and/or the net
          revenues from housing or other

                                                                              31
<PAGE>

          public projects. Some authorities provide further security in the form
          of a state's ability (without obligation) to make up deficiencies in
          the debt service reserve fund.

          In recent years, revenue bonds have been issued in large volumes for
          projects that are privately owned and operated (see 3 below).

          3. Private Activity Bonds are considered municipal bonds if the
          interest paid thereon is exempt from Federal income tax and are issued
          by or on behalf of public authorities to raise money to finance
          various privately operated facilities for business and manufacturing,
          housing and health. These bonds are also used to finance public
          facilities such as airports, mass transit systems and ports. The
          payment of the principal and interest on such bonds is dependent
          solely on the ability of the facility's user to meet its financial
          obligations and the pledge, if any, of real and personal property as
          security for such payment.

          While, at one time, the pertinent provisions of the Internal Revenue
          Code permitted private activity bonds to bear tax-exempt interest in
          connection with virtually any type of commercial or industrial project
          (subject to various restrictions as to authorized costs, size
          limitations, state per capita volume restrictions, and other matters),
          the types of qualifying projects under the Code have become
          increasingly limited, particularly since the enactment of the Tax
          Reform Act of 1986. Under current provisions of the Code, tax-exempt
          financing remains available, under prescribed conditions, for certain
          privately owned and operated rental multi-family housing facilities,
          nonprofit hospital and nursing home projects, airports, docks and
          wharves, mass commuting facilities and solid waste disposal projects,
          among others, and for the refunding (that is, the tax-exempt
          refinancing) of various kinds of other private commercial projects
          originally financed with tax-exempt bonds. In future years, the types
          of projects qualifying under the Code for tax-exempt financing are
          expected to become increasingly limited.

          Because of terminology formerly used in the Internal Revenue Code,
          virtually any form of private activity bond may still be referred to
          as an "industrial development bond," but more and more frequently
          revenue bonds have become classified according to the particular type
          of facility being financed, such as hospital revenue bonds, nursing
          home revenue bonds, multi-family housing revenues bonds, single family
          housing revenue bonds, industrial development revenue bonds, solid
          waste resource recovery revenue bonds, and so on.

          OTHER MUNICIPAL OBLIGATIONS, incurred for a variety of financing
          purposes, include: municipal leases, which may take the form of a
          lease or an installment purchase or conditional sale contract, are
          issued by state and local governments and authorities to acquire a
          wide variety of equipment and facilities such as fire and sanitation
          vehicles, telecommunications equipment and other capital assets.
          Municipal leases frequently have special risks not normally associated
          with general obligation or revenue bonds. Leases and installment
          purchase or conditional sale contracts (which normally provide for
          title to the leased asset to pass eventually to the government issuer)
          have evolved as a means for governmental issuers to acquire property
          and equipment without meeting the constitutional and statutory
          requirements for the issuance of debt. The debt-issuance limitations
          of many state constitutions and statutes are deemed to be inapplicable
          because of the inclusion in many leases or contracts of
          "non-appropriation" clauses that provide that the governmental issuer
          has no obligation to make future payments under the lease or contract
          unless money is appropriated for such purpose by the appropriate
          legislative body on a yearly or other periodic basis. To reduce this
          risk, the Fund will only purchase municipal leases subject to a
          non-appropriation clause when the payment of principal and accrued
          interest is backed by an unconditional irrevocable letter of credit,
          or guarantee of a bank or other entity that meets the criteria
          described in the Prospectus.

   32
<PAGE>

          Tax-exempt bonds are also categorized according to whether the
          interest is or is not includible in the calculation of alternative
          minimum taxes imposed on individuals, according to whether the costs
          of acquiring or carrying the bonds are or are not deductible in part
          by banks and other financial institutions, and according to other
          criteria relevant for Federal income tax purposes. Due to the
          increasing complexity of Internal Revenue Code and related
          requirements governing the issuance of tax-exempt bonds, industry
          practice has uniformly required, as a condition to the issuance of
          such bonds, but particularly for revenue bonds, an opinion of
          nationally recognized bond counsel as to the tax-exempt status of
          interest on the bonds.

                                                                              33

Investment restrictions and investment strategies

INVESTMENT RESTRICTIONS

          The Portfolio has adopted certain fundamental investment restrictions
          that cannot be changed without shareholder approval. Shareholder
          approval means approval by the lesser of (i) more than 50% of the
          outstanding voting securities of the Trust (or the Portfolio or class
          of shares if a matter affects just the Portfolio or class of shares),
          or (ii) 67% or more of the voting securities present at a meeting if
          the holders of more than 50% of the outstanding voting securities of
          the Trust (or the Portfolio or class of shares) are present or
          represented by proxy.

          As used in the restrictions set forth below and as used elsewhere in
          this SAI, the term "U.S. Government Securities" shall have the meaning
          set forth in the Investment Company Act of 1940, as amended (the "1940
          Act"). The 1940 Act defines U.S. Government Securities as securities
          issued or guaranteed by the United States government, its agencies or
          instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized and municipal securities escrowed
          with or refunded with escrowed U.S. government securities.

          The Portfolio has adopted the following fundamental policies:

          (1) With respect to 75% of its assets, the Portfolio may not purchase
          a security other than a U.S. Government Security, if, as a result,
          more than 5% of its total assets would be invested in the securities
          of a single issuer or the Portfolio would own more than 10% of the
          outstanding voting securities of any single issuer. (As noted in the
          Prospectus, the Portfolio is currently subject to the greater
          diversification standards of Rule 2a-7, which are not fundamental.)

          (2) The Portfolio may not purchase securities if 25% or more of the
          value of its total assets would be invested in the securities of
          issuers conducting their principal business activities in the same
          industry; provided that: (i) there is no limit on investments in U.S.
          Government Securities or in obligations of domestic commercial banks
          (including U.S. branches of foreign banks subject to regulations under
          U.S. laws applicable to domestic banks and, to the extent that its
          parent is unconditionally liable for the obligation, foreign branches
          of U.S. banks); (ii) this limitation shall not apply to the
          Portfolio's investments in municipal securities; (iii) there is no
          limit on investment in issuers domiciled in a single country; (iv)
          financial service companies are classified according to the end users
          of their services (for example, automobile finance, bank finance and
          diversified finance are each considered to be a separate industry);
          and (v) utility companies are classified according to their services
          (for example, gas, gas transmission, electric, and telephone are each
          considered to be a separate industry).

          (3) The Portfolio may not act as an underwriter of securities issued
          by others, except to the extent that it may be deemed an underwriter
          in connection with the disposition of its portfolio securities.

          (4) The Portfolio may not lend any security or make any other loan if,
          as a result, more than 25% of its total assets would be lent to other
          parties (but this limitation does not apply to purchases of commercial
          paper, debt securities or repurchase agreements).

          (5) The Portfolio may not purchase or sell real estate or any interest
          therein, except that the Portfolio may invest in debt obligations
          secured by real estate or interests therein or securities issued by
          companies that invest in real estate or interests therein.

          (6) The Portfolio may borrow money for temporary or emergency purposes
          (not for leveraging) in an amount not exceeding 25% of the value of
          its total assets (including the amount borrowed) less liabilities
          (other than borrowings). If borrowings exceed 25% of the value of the
          Portfolio's total assets by reason of a decline in net assets, it will
          reduce its borrowings within three business days to the extent
          necessary to comply with the 25% limitation. Reverse repurchase
          agreements or the segregation of assets in connection with such
          agreements shall not be considered borrowing for the purposes of this
          limit.

<PAGE>

          (7) The Portfolio may, notwithstanding any other investment policy or
          restriction (whether or not fundamental), invest all of its assets in
          the securities of a single open-end management investment company with
          substantially the same fundamental investment objectives, policies and
          restrictions as the Portfolio.

          Investment restriction (1) is intended to reflect the requirements
          under Section 5(b)(1) of the 1940 Act for a diversified fund. Rule
          2a-7 provides that money market funds that comply with the
          diversification limits of Rule 2a-7 are deemed to comply with the
          diversification limits of Section 5(b)(1). Thus, the Portfolio
          interprets restriction (1) in accordance with Rule 2a-7. Accordingly,
          if securities are subject to a guarantee provided by a non-controlled
          person, the Rule 2a-7 diversification tests apply to the guarantor,
          and the diversification test in restriction (1) does not apply to the
          issuer.

          The Portfolio has adopted the following nonfundamental investment
          restrictions that may be changed by the Trustees without shareholder
          approval:

          (1) The Portfolio may not invest in securities or enter into
          repurchase agreements with respect to any securities if, as a result,
          more than 10% of its net assets would be invested in repurchase
          agreements not entitling the holder to payment of principal within
          seven days and in other securities that are not readily marketable
          ("illiquid securities"). The Trustees, or the Portfolio's investment
          adviser acting pursuant to authority delegated by the Trustees, may
          determine that a readily available market exists for certain
          securities such as securities eligible for resale pursuant to Rule
          144A under the Securities Act of 1933, or any successor to such rule,
          Section 4(2) commercial paper and municipal lease obligations.
          Accordingly, such securities may not be subject to the foregoing
          limitation.

          (2) The Portfolio may not purchase securities on margin, or make short
          sales of securities, except for short sales against the box and the
          use of short-term credit necessary for the clearance of purchases and
          sales of portfolio securities.

          (3) The Portfolio may not pledge, mortgage, hypothecate or encumber
          any of its assets except to secure permitted borrowings or in
          connection with permitted short sales.

          (4) The Portfolio may not invest in companies for the purpose of
          exercising control of management.

          Under the terms of an exemptive order received from the Securities and
          Exchange Commission ("SEC"), the Portfolio may borrow money from or
          lend money to other funds that permit such transactions and for which
          Janus Capital serves as investment adviser. All such borrowing and
          lending will be subject to the above limits. The Portfolio will borrow
          money through the program only when the costs are equal to or lower
          than the cost of bank loans. Interfund loans and borrowings normally
          extend overnight, but can have a maximum duration of seven days. The
          Portfolio will lend through the program only when the returns are
          higher than those available from other short-term instruments (such as
          repurchase agreements). The Portfolio may have to borrow from a bank
          at a higher interest rate if an interfund loan is called or not
          renewed. Any delay in repayment to a lending Portfolio could result in
          a lost investment opportunity or additional borrowing costs.

          For purposes of the Portfolio's policies on investing in particular
          industries, the Portfolio will rely primarily on industry or industry
          group classifications as published by Bloomberg L.P. To the extent
          that Bloomberg L.P. industry classifications are so broad that the
          primary economic characteristics in a single industry are materially
          different, the Portfolio may further classify issuers in accordance
          with industry classifications as published by the SEC.

                                                                               3

INVESTMENT STRATEGIES

          The Portfolio may invest only in "eligible securities" as defined in
          Rule 2a-7 adopted under the 1940 Act. Generally, an eligible security
          is a security that (i) is denominated in U.S. dollars and has a
          remaining maturity of 397 days or less (as calculated pursuant to Rule
          2a-7); (ii) is rated, or is issued by an issuer with short-term debt
          outstanding that is rated, in one of the two highest rating categories
          by any two nationally recognized statistical rating organizations
          ("NRSROs") or, if only one NRSRO has issued a rating, by that NRSRO
          (the "Requisite NRSROs") or is unrated and of comparable quality to a
          rated security, as determined by Janus Capital; and (iii) has been
          determined by Janus Capital to present minimal credit risks pursuant
          to procedures approved by the Trustees. In addition, the Portfolio
          will maintain a dollar-weighted average portfolio maturity of 90 days
          or less. A description of the ratings of some NRSROs appears in
          Appendix A.

          Under Rule 2a-7, the Portfolio may not invest more than five percent
          of its total assets in the securities of any one issuer other than
          U.S. Government Securities, provided that in certain cases it may
          invest more than 5% of its assets in a single issuer for a period of
          up to three business days. Investment in demand features, guarantees
          and other types of instruments or features are subject to the
          diversification limits under Rule 2a-7.

          Pursuant to Rule 2a-7, the Portfolio will invest at least 95% of its
          total assets in "first-tier" securities. First-tier securities are
          eligible securities that are rated, or are issued by an issuer with
          short-term debt outstanding that is rated, in the highest rating
          category by the Requisite NRSROs or are unrated and of comparable
          quality to a rated security. In addition, the Portfolio may invest in
          "second-tier" securities which are eligible securities that are not
          first-tier securities. However, the Portfolio may not invest in a
          second-tier security if immediately after the acquisition thereof it
          would have invested more than (i) the greater of one percent of its
          total assets or one million dollars in second-tier securities issued
          by that issuer, or (ii) five percent of its total assets in
          second-tier securities.

          The following discussion of types of securities in which the Portfolio
          may invest supplements and should be read in conjunction with the
          Prospectus.

Participation Interests

          The Portfolio may purchase participation interests in loans or
          securities in which it may invest directly. Participation interests
          are generally sponsored or issued by banks or other financial
          institutions. A participation interest gives the Portfolio an
          undivided interest in the underlying loans or securities in the
          proportion that the Portfolio's interest bears to the total principal
          amount of the underlying loans or securities. Participation interests,
          which may have fixed, floating or variable rates, may carry a demand
          feature backed by a letter of credit or guarantee of a bank or
          institution permitting the holder to tender them back to the bank or
          other institution. For certain participation interests, the Portfolio
          will have the right to demand payment, on not more than seven days'
          notice, for all or a part of the Portfolio's participation interest.
          The Portfolio intends to exercise any demand rights it may have upon
          default under the terms of the loan or security, to provide liquidity
          or to maintain or improve the quality of the Portfolio's investment
          portfolio. The Portfolio will only purchase participation interests
          that Janus Capital determines present minimal credit risks.

Variable and Floating Rate Notes

          The Portfolio also may purchase variable and floating rate demand
          notes of corporations, which are unsecured obligations redeemable upon
          not more than 30 days' notice. These obligations include master demand
          notes that permit investment of fluctuating amounts at varying rates
          of interest pursuant to direct

 4
<PAGE>

          arrangements with the issuer of the instrument. The issuer of these
          obligations often has the right, after a given period, to prepay the
          outstanding principal amount of the obligations upon a specified
          number of days' notice. These obligations generally are not traded,
          nor generally is there an established secondary market for these
          obligations. To the extent a demand note does not have a seven day or
          shorter demand feature and there is no readily available market for
          the obligation, it is treated as an illiquid investment.

          Securities with ultimate maturities of greater than 397 days may be
          purchased only pursuant to Rule 2a-7. Under that Rule, only those
          long-term instruments that have demand features which comply with
          certain requirements and certain variable rate U.S. Government
          Securities may be purchased. The rate of interest on securities
          purchased by the Portfolio may be tied to short-term Treasury or other
          government securities or indices on securities that are permissible
          investments of the Portfolio, as well as other money market rates of
          interest. The Portfolio will not purchase securities whose values are
          tied to interest rates or indices that are not appropriate for the
          duration and volatility standards of a money market fund.

Mortgage- and Asset-Backed Securities

          The Portfolio may invest in mortgage-backed securities, which
          represent an interest in a pool of mortgages made by lenders such as
          commercial banks, savings and loan institutions, mortgage bankers,
          mortgage brokers and savings banks. Mortgage-backed securities may be
          issued by governmental or government-related entities or by
          non-governmental entities such as banks, savings and loan
          institutions, private mortgage insurance companies, mortgage bankers
          and other secondary market issuers.

          Interests in pools of mortgage-backed securities differ from other
          forms of debt securities which normally provide for periodic payment
          of interest in fixed amounts with principal payments at maturity or
          specified call dates. In contrast, mortgage-backed securities provide
          periodic payments which consist of interest and, in most cases,
          principal. In effect, these payments are a "pass-through" of the
          periodic payments and optional prepayments made by the individual
          borrowers on their mortgage loans, net of any fees paid to the issuer
          or guarantor of such securities. Additional payments to holders of
          mortgage-backed securities are caused by prepayments resulting from
          the sale of the underlying residential property, refinancing or
          foreclosure, net of fees or costs which may be incurred.

          As prepayment rates of individual pools of mortgage loans vary widely,
          it is not possible to predict accurately the average life of a
          particular security. Although mortgage-backed securities are issued
          with stated maturities of up to forty years, unscheduled or early
          payments of principal and interest on the underlying mortgages may
          shorten considerably the effective maturities. Mortgage-backed
          securities may have varying assumptions for average life. The volume
          of prepayments of principal on a pool of mortgages underlying a
          particular security will influence the yield of that security, and the
          principal returned to the Portfolio may be reinvested in instruments
          whose yield may be higher or lower than that which might have been
          obtained had the prepayments not occurred. When interest rates are
          declining, prepayments usually increase, with the result that
          reinvestment of principal prepayments will be at a lower rate than the
          rate applicable to the original mortgage-backed security.

          The Portfolio may invest in mortgage-backed securities that are issued
          by agencies or instrumentalities of the U.S. government. The
          Government National Mortgage Association ("GNMA") is the principal
          federal government guarantor of mortgage-backed securities. GNMA is a
          wholly-owned U.S. government corporation within the Department of
          Housing and Urban Development. GNMA Certificates are debt securities
          which represent an interest in one mortgage or a pool of mortgages
          which are insured by the Federal Housing Administration or the Farmers
          Home Administration or are guaranteed by the Veterans Administration.
          The Portfolio may also invest in pools of conventional mortgages which
          are issued or

                                                                               5
<PAGE>

          guaranteed by agencies of the U.S. government. GNMA pass-through
          securities are considered to be riskless with respect to default in
          that (i) the underlying mortgage loan portfolio is comprised entirely
          of government-backed loans and (ii) the timely payment of both
          principal and interest on the securities is guaranteed by the full
          faith and credit of the U.S. government, regardless of whether or not
          payments have been made on the underlying mortgages. GNMA pass-through
          securities are, however, subject to the same market risk as comparable
          debt securities. Therefore, the market value of the Portfolio's GNMA
          securities can be expected to fluctuate in response to changes in
          prevailing interest rate levels.

          Residential mortgage loans are pooled also by the Federal Home Loan
          Mortgage Corporation ("FHLMC"). FHLMC is a privately managed, publicly
          chartered agency created by Congress in 1970 for the purpose of
          increasing the availability of mortgage credit for residential
          housing. FHLMC issues participation certificates ("PCs") which
          represent interests in mortgages from FHLMC's national portfolio. The
          mortgage loans in FHLMC's portfolio are not U.S. government backed;
          rather, the loans are either uninsured with loan-to-value ratios of
          80% or less, or privately insured if the loan-to-value ratio exceeds
          80%. FHLMC guarantees the timely payment of interest and ultimate
          collection of principal on FHLMC PCs; the U.S. government does not
          guarantee any aspect of FHLMC PCs.

          The Federal National Mortgage Association ("FNMA") is a
          government-sponsored corporation owned entirely by private
          shareholders. It is subject to general regulation by the Secretary of
          Housing and Urban Development. FNMA purchases residential mortgages
          from a list of approved seller/servicers which include savings and
          loan associations, savings banks, commercial banks, credit unions and
          mortgage bankers. FNMA guarantees the timely payment of principal and
          interest on the pass-through securities issued by FNMA; the U.S.
          government does not guarantee any aspect of the FNMA pass-through
          securities.

          The Portfolio may also invest in privately-issued mortgage-backed
          securities to the extent permitted by their investment restrictions.
          Mortgage-backed securities offered by private issuers include
          pass-through securities comprised of pools of conventional residential
          mortgage loans; mortgage-backed bonds which are considered to be debt
          obligations of the institution issuing the bonds and which are
          collateralized by mortgage loans; and collateralized mortgage
          obligations ("CMOs") which are collateralized by mortgage-backed
          securities issued by GNMA, FHLMC or FNMA or by pools of conventional
          mortgages.

          Asset-backed securities represent direct or indirect participation in,
          or are secured by and payable from, assets other than mortgage-backed
          assets such as motor vehicle installment sales contracts, installment
          loan contracts, leases of various types of real and personal property
          and receivables from revolving credit agreements (credit cards).
          Asset-backed securities have yield characteristics similar to those of
          mortgage-backed securities and, accordingly, are subject to many of
          the same risks.

Reverse Repurchase Agreements

          Reverse repurchase agreements are transactions in which the Portfolio
          sells a security and simultaneously commits to repurchase that
          security from the buyer at an agreed upon price on an agreed upon
          future date. The resale price in a reverse repurchase agreement
          reflects a market rate of interest that is not related to the coupon
          rate or maturity of the sold security. For certain demand agreements,
          there is no agreed upon repurchase date and interest payments are
          calculated daily, often based upon the prevailing overnight repurchase
          rate. The Portfolio will use the proceeds of reverse repurchase
          agreements only to satisfy unusually heavy redemption requests or for
          other temporary or emergency purposes without the necessity of selling
          portfolio securities.

          Generally, a reverse repurchase agreement enables the Portfolio to
          recover for the term of the reverse repurchase agreement all or most
          of the cash invested in the portfolio securities sold and to keep the

 6
<PAGE>

          interest income associated with those portfolio securities. Such
          transactions are only advantageous if the interest cost to the
          Portfolio of the reverse repurchase transaction is less than the cost
          of obtaining the cash otherwise. In addition, interest costs on the
          money received in a reverse repurchase agreement may exceed the return
          received on the investments made by the Portfolio with those monies.

When Issued and Delayed Delivery Securities

          The Portfolio may purchase securities on a when-issued or delayed
          delivery basis. The Portfolio will enter into such transactions only
          when it has the intention of actually acquiring the securities. To
          facilitate such acquisitions, the Portfolio's custodian will segregate
          cash or high quality liquid assets in an amount at least equal to such
          commitments. On delivery dates for such transactions, the Portfolio
          will meet its obligations from maturities, sales of the segregated
          securities or from other available sources of cash. If it chooses to
          dispose of the right to acquire a when-issued security prior to its
          acquisition, the Portfolio could, as with the disposition of any other
          portfolio obligation, incur a gain or loss due to market fluctuation.
          At the time it makes the commitment to purchase securities on a
          when-issued or delayed delivery basis, the Portfolio will record the
          transaction as a purchase and thereafter reflect the value of such
          securities in determining its net asset value.

Investment Company Securities

          From time to time, the Portfolio may invest in securities of other
          investment companies. The Portfolio is subject to the provisions of
          Section 12(d)(1) of the 1940 Act. The Portfolio may invest in
          securities of money market funds managed by Janus Capital in excess of
          the limitations of Section 12(d)(1) under the terms of an SEC
          exemptive order obtained by Janus Capital and the Janus Funds.

Debt Obligations


          Money Market Portfolio may invest in U.S. dollar denominated debt
          obligations. In general, sales of these securities may not be made
          absent registration under the Securities Act of 1933 or the
          availability of an appropriate exemption. Pursuant to Section 4(2) of
          the 1933 Act or Rule 144A adopted under the 1933 Act, however, some of
          these securities are eligible for resale to institutional investors,
          and accordingly, Janus Capital may determine that a liquid market
          exists for such a security pursuant to guidelines adopted by the
          Trustees.


Obligations of Financial Institutions

          The Portfolio may invest in obligations of financial institutions.
          Examples of obligations in which the Portfolio may invest include
          negotiable certificates of deposit, bankers' acceptances, time
          deposits and other obligations of U.S. banks (including savings and
          loan associations) having total assets in excess of one billion
          dollars and U.S. branches of foreign banks having total assets in
          excess of ten billion dollars. The Portfolio may also invest in
          Eurodollar and Yankee bank obligations as discussed below and other
          U.S. dollar-denominated obligations of foreign banks having total
          assets in excess of ten billion dollars that Janus Capital believes
          are of an investment quality comparable to obligations of U.S. banks
          in which the Portfolio may invest.

          Certificates of deposit represent an institution's obligation to repay
          funds deposited with it that earn a specified interest rate over a
          given period. Bankers' acceptances are negotiable obligations of a
          bank to pay a draft which has been drawn by a customer and are usually
          backed by goods in international trade. Time deposits are
          non-negotiable deposits with a banking institution that earn a
          specified interest rate over a given period. Fixed time deposits,
          which are payable at a stated maturity date and bear a fixed rate of
          interest, generally may be withdrawn on demand by the Portfolio but
          may be subject to early withdrawal

                                                                               7
<PAGE>

          penalties and that could reduce the Portfolio's yield. Unless there is
          a readily available market for them, time deposits that are subject to
          early withdrawal penalties and that mature in more than seven days
          will be treated as illiquid securities.

          Eurodollar bank obligations are dollar-denominated certificates of
          deposit or time deposits issued outside the U.S. capital markets by
          foreign branches of U.S. banks and by foreign banks. Yankee bank
          obligations are dollar-denominated obligations issued in the U.S.
          capital markets by foreign banks.

          Foreign, Eurodollar (and to a limited extent, Yankee) bank obligations
          are subject to certain sovereign risks. One such risk is the
          possibility that a foreign government might prevent dollar-denominated
          funds from flowing across its borders. Other risks include: adverse
          political and economic developments in a foreign country; the extent
          and quality of government regulation of financial markets and
          institutions; the imposition of foreign withholding taxes; and
          exploration or nationalization of foreign issuers.

U.S. Government Securities

          Money Market Portfolio may invest in U.S. Government Securities. U.S.
          Government Securities shall have the meaning set forth in the 1940
          Act. The 1940 Act defines U.S. Government Securities to include
          securities issued or guaranteed by the U.S. Government, its agencies
          and instrumentalities. U.S. Government Securities may also include
          repurchase agreements collateralized by and municipal securities
          escrowed with or refunded with U.S. government securities. U.S.
          Government Securities in which the Portfolio may invest include U.S.
          Treasury securities and obligations issued or guaranteed by U.S.
          government agencies and instrumentalities that are backed by the full
          faith and credit of the U.S. government, such as those guaranteed by
          the Small Business Administration or issued by the Government National
          Mortgage Association. In addition, U.S. Government Securities in which
          the Portfolio may invest include securities supported primarily or
          solely by the creditworthiness of the issuer, such as securities of
          the Federal National Mortgage Association, the Federal Home Loan
          Mortgage Corporation and the Tennessee Valley Authority. There is no
          guarantee that the U.S. government will support securities not backed
          by its full faith and credit. Accordingly, although these securities
          have historically involved little risk of loss of principal if held to
          maturity, they may involve more risk than securities backed by the
          full faith and credit of the U.S. government.

Municipal Leases

          The Portfolio may invest in municipal leases. Municipal leases
          frequently have special risks not normally associated with general
          obligation or revenue bonds. Municipal leases are municipal securities
          which may take the form of a lease or an installment purchase or
          conditional sales contract. Municipal leases are issued by state and
          local governments and authorities to acquire a wide variety of
          equipment and facilities. Leases and installment purchase or
          conditional sale contracts (which normally provide for title to the
          leased asset to pass eventually to the government issuer) have evolved
          as a means for governmental issuers to acquire property and equipment
          without meeting the constitutional and statutory requirements for the
          issuance of debt. The debt-issuance limitations of many state
          constitutions and statutes are deemed to be inapplicable because of
          the inclusion in many leases or contracts of "non-appropriation"
          clauses that provide that the governmental issuer has no obligation to
          make future payments under the lease or contract unless money is
          appropriated for such purpose by the appropriate legislative body on a
          yearly or other periodic basis. The Portfolio will only purchase
          municipal leases subject to a non-appropriation clause when the
          payment of principal and accrued interest is backed by an
          unconditional irrevocable letter of credit, or guarantee of a bank or
          other entity that meets the criteria described in the Prospectus under
          "Taxable Investments."

          In evaluating municipal lease obligations, Janus Capital will consider
          such factors as it deems appropriate, including: (a) whether the lease
          can be canceled; (b) the ability of the lease obligee to direct the
          sale of the underlying assets; (c) the general creditworthiness of the
          lease obligor; (d) the likelihood that the municipality will
          discontinue appropriating funding for the leased property in the event
          such property is no longer considered essential by the municipality;
          (e) the legal recourse of the lease obligee in the event of such a
          failure to appropriate funding; (f) whether the security is backed by
          a credit enhancement such as insurance; and (g) any limitations which
          are imposed on the lease obligor's ability to utilize substitute
          property or services other than those covered by the lease obligation.
          If a lease is backed by an unconditional letter of credit or other
          unconditional credit enhancement, then Janus Capital may determine
          that a lease is an eligible security solely on the basis of its
          evaluation of the credit enhancement.

          Municipal leases, like other municipal debt obligations, are subject
          to the risk of non-payment. The ability of issuers of municipal leases
          to make timely lease payments may be adversely impacted in general
          economic downturns and as relative governmental cost burdens are
          allocated and reallocated among federal, state and local governmental
          units. Such non-payment would result in a reduction of income to the
          Portfolio, and could result in a reduction in the value of the
          municipal lease experiencing non-payment and a potential decrease in
          the net asset value of the Portfolio.

                                                                               9

Performance data

          The Portfolio may provide current annualized and effective annualized
          yield quotations of the Shares based on the Shares' daily dividends.
          These quotations may from time to time be used in advertisements,
          shareholder reports or other communications to shareholders. All
          performance information supplied by the Portfolio in advertising is
          historical and is not intended to indicate future returns.

          In performance advertising, the Portfolio may compare any of its
          performance information with data published by independent evaluators
          such as Morningstar, Inc., Lipper Analytical Services, Inc., or
          CDC/Wiesenberger, Donoghue's Money Fund Report or other companies
          which track the investment performance of investment companies ("Fund
          Tracking Companies"). The Portfolio may also compare its performance
          information with the performance of recognized stock, bond and other
          indices, including but not limited to the Municipal Bond Buyers
          Indices, the Salomon Brothers Bond Index, the Lehman Brothers Bond
          Index, the Standard & Poor's 500 Composite Stock Price Index, the Dow
          Jones Industrial Average, U.S. Treasury bonds, bills or notes and
          changes in the Consumer Price Index as published by the U.S.
          Department of Commerce. The Portfolio may refer to general market
          performance over past time periods such as those published by Ibbotson
          Associates (for instance, its "Stocks, Bonds, Bills and Inflation
          Yearbook"). The Portfolio may also refer in such materials to mutual
          fund performance rankings and other data published by Fund Tracking
          Companies. Performance advertising may also refer to discussions of
          the Portfolio and comparative mutual fund data and ratings reported in
          independent periodicals, such as newspapers and financial magazines.

          Any current yield quotation of the Portfolio's Shares which is used in
          such a manner as to be subject to the provisions of Rule 482(d) under
          the Securities Act of 1933, as amended, shall consist of an annualized
          historical yield, carried at least to the nearest hundredth of one
          percent, based on a specific seven calendar day period. The current
          yield of the Portfolio's Shares shall be calculated by (a) determining
          the net change during a seven calendar day period in the value of a
          hypothetical account having a balance of one share at the beginning of
          the period, (b) dividing the net change by the value of the account at
          the beginning of the period to obtain a base period return, and (c)
          multiplying the quotient by 365/7 (i.e., annualizing). For this
          purpose, the net change in account value will reflect the value of
          additional shares purchased with dividends declared on the original
          share and dividends declared on both the original share and any such
          additional shares, but will not reflect any realized gains or losses
          from the sale of securities or any unrealized appreciation or
          depreciation on portfolio securities. In addition, the Portfolio may
          advertise effective yield quotations. Effective yield quotations are
          calculated by adding 1 to the base period return, raising the sum to a
          power equal to 365/7, and subtracting 1 from the result (i.e.,
          compounding).

          Income calculated for the purpose of determining the yield of the
          Portfolio's Shares differs from income as determined for other
          accounting purposes. Because of the different accounting methods used,
          and because of the compounding assumed in yield calculations, the
          yield quoted for the Portfolio's Shares may differ from the rate of
          distribution the Shares paid over the same period or the rate of
          income reported in the Portfolio's financial statements.

          Although published yield information is useful to investors in
          reviewing the performance of the Portfolio's Shares, investors should
          be aware that the yield fluctuates from day to day and that the
          Share's yield for any given period is not an indication or
          representation by the Portfolio of future yields or rates of return on
          the Portfolio's Shares. The Shares' yield is not fixed or guaranteed,
          and an investment in the Portfolio is not insured. Accordingly, the
          Shares' yield information may not necessarily be used to compare
          Portfolio Shares with investment alternatives which, like money market
          instruments or bank accounts, may provide a fixed rate of interest. In
          addition, because investments in the Portfolio are not insured or
          guaranteed, the yield information may not necessarily be used to
          compare the Portfolio with investment alternatives which are insured
          or guaranteed.

Determination of net asset value

          Pursuant to the rules of the SEC, the Trustees have established
          procedures to stabilize the Portfolio's net asset value at $1.00 per
          Share. These procedures include a review of the extent of any
          deviation of net asset value per Share as a result of fluctuating
          interest rates, based on available market rates, from the Portfolio's
          $1.00 amortized cost price per Share. Should that deviation exceed
          1/2 of 1%, the Trustees will consider whether any action should be
          initiated to eliminate or reduce material dilution or other unfair
          results to shareholders. Such action may include redemption of shares
          in kind, selling portfolio securities prior to maturity, reducing or
          withholding dividends and utilizing a net asset value per share as
          determined by using available market quotations. The Portfolio i) will
          maintain a dollar-weighted average portfolio maturity of 90 days or
          less; ii) will not purchase any instrument with a remaining maturity
          greater than 397 days or subject to a repurchase agreement having a
          duration of greater than 397 days; iii) will limit portfolio
          investments, including repurchase agreements, to those U.S.
          dollar-denominated instruments that Janus Capital has determined
          present minimal credit risks pursuant to procedures established by the
          Trustees; and iv) will comply with certain reporting and recordkeeping
          procedures. The Trust has also established procedures to ensure that
          portfolio securities meet the Portfolio's high quality criteria.

                                                                              11

Investment adviser

          As stated in the Prospectus, the Portfolio has an Investment Advisory
          Agreement with Janus Capital, 100 Fillmore Street, Denver, Colorado
          80206-4928. The Advisory Agreement provides that Janus Capital will
          furnish continuous advice and recommendations concerning the
          Portfolio's investments, provide office space for the Portfolio and
          pay the salaries, fees and expenses of all Portfolio officers and of
          those Trustees who are affiliated with Janus Capital. Janus Capital
          also may make payments to selected broker-dealer firms or institutions
          which were instrumental in the acquisition of shareholders for the
          Portfolio or which performed services with respect to shareholder
          accounts. The minimum aggregate size required for eligibility for such
          payments, and the factors in selecting the broker-dealer firms and
          institutions to which they will be made, are determined from time to
          time by Janus Capital. Janus Capital is also authorized to perform the
          management and administrative services necessary for the operation of
          the Portfolio.

          The Portfolio pays custodian agent fees and expenses, brokerage
          commissions and dealer spreads and other expenses in connection with
          the execution of Portfolio transactions, legal and accounting
          expenses, interest and taxes, registration fees, expenses of
          shareholders' meetings, and reports to shareholders, fees and expenses
          of Trustees who are not affiliated with Janus Capital, and other costs
          of complying with applicable laws regulating the sale of Portfolio
          shares. Pursuant to the Advisory Agreement, Janus Capital furnishes
          certain other services, including net asset value determination,
          portfolio accounting and record keeping for which the Portfolio may
          reimburse Janus Capital for its costs.

          The Portfolio has agreed to compensate Janus Capital for its advisory
          services by the monthly payment of an advisory fee at the annual rate
          of .25% of the Portfolio's average daily net assets. Janus Capital has
          agreed to reimburse the Portfolio by the amount, if any, that the
          Portfolio's normal operating expenses in any fiscal year, including
          the investment advisory fee but excluding the distribution fee
          described below, brokerage commissions, interest, taxes and
          extraordinary expenses, exceed .50% of average daily net assets. Janus
          Capital has agreed to continue such waivers until at least the next
          annual renewal of the advisory agreements. Mortality risk, expense
          risk and other charges imposed by participating insurance companies
          are also excluded from the above expense limitation.


          For the fiscal year ended December 31, 1999, the advisory fee was
          $137,596. For the fiscal year ended December 31, 1998 and December 31,
          1997, the advisory fees were $79,201 and $22,333, respectively. For
          the fiscal year ended December 31, 1997, Janus Capital waived $2,184.



          The Advisory Agreement is dated July 1, 1997 and will continue in
          effect until July 1, 2001, and thereafter from year to year so long as
          such continuance is approved annually by a majority of the Portfolio's
          Trustees who are not parties to the Advisory Agreement or interested
          persons of any such party, and by either a majority of the outstanding
          voting shares or the Trustees. The Advisory Agreement i) may be
          terminated without the payment of any penalty by the Portfolio or
          Janus Capital on 60 days' written notice; ii) terminates automatically
          in the event of its assignment; and iii) generally, may not be amended
          without the approval by vote of a majority of the Trustees, including
          the Trustees who are not interested persons of the Portfolio or Janus
          Capital and, to the extent required by the 1940 Act, the vote of a
          majority of the outstanding voting securities of the Portfolio.


          Janus Capital also acts as sub-advisor for a number of private-label
          mutual funds and provides separate account advisory services for
          institutional accounts. Investment decisions for each account managed
          by Janus Capital, including the Portfolio, are made independently from
          those for any other account that is or may in the future become
          managed by Janus Capital or its affiliates. If, however, a number of
          accounts managed by Janus Capital are contemporaneously engaged in the
          purchase or sale of the same security, the orders may be aggregated
          and/or the transactions may be averaged as to price and allocated
          equitably to each account. In some cases, this policy might adversely
          affect the price paid or received by an account or the size of the
          position obtained or liquidated for an account. Pursuant to an
          exemptive order granted by

 12
<PAGE>

          the SEC, the Portfolios and other funds advised by Janus Capital may
          also transfer daily uninvested cash balances into one or more joint
          trading accounts. Assets in the joint trading accounts are invested in
          money market instruments and the proceeds are allocated to the
          participating funds on a pro rata basis.


          Kansas City Southern Industries, Inc. ("KCSI"), indirectly through its
          wholly owned subsidiary, Stilwell Financial Inc., owns approximately
          81% of the outstanding voting stock of Janus Capital. KCSI is a
          publicly traded holding company whose primary subsidiaries are engaged
          in transportation, information processing and financial services.
          Thomas H. Bailey, President and Chairman of the Board of Janus
          Capital, owns approximately 12% of Janus Capital's voting stock and,
          by agreement with KCSI, selects at least a majority of Janus Capital's
          Board.



          KCSI has announced its intention to separate its transportation and
          financial services businesses. KCSI anticipates the separation to be
          completed in the first half of 2000.


          Each account managed by Janus Capital has its own investment objective
          and is managed in accordance with that objective by a particular
          portfolio manager or team of portfolio managers. As a result, from
          time to time two or more different managed accounts may pursue
          divergent investment strategies with respect to investments or
          categories of investments.


          Janus Capital does not permit portfolio managers to purchase and sell
          securities for their own accounts except under the limited exceptions
          contained in the Portfolio's Code of Ethics ("Code"). The Portfolio's
          Code of Ethics is on file with and available from the SEC through the
          SEC Web site at www.sec.gov. The Code applies to Directors/Trustees of
          Janus Capital and the Portfolios and employees of Janus Capital and
          the Trust, and requires investment personnel and officers of Janus
          Capital, inside Directors/Trustees of Janus Capital and the Portfolio
          and other certain designated employees deemed to have access to
          current trading information to pre-clear all transactions in
          securities not otherwise exempt under the Code. Requests for trading
          authorization will be denied when, among other reasons, the proposed
          personal transaction would be contrary to the provisions of the Code
          or would be deemed to adversely affect any transaction then known to
          be under consideration for or to have been effected on behalf of any
          client account, including the Portfolio.



          In addition to the pre-clearance requirement described above, the Code
          subjects such personnel, to various trading restrictions and reporting
          obligations. All reportable transactions are required to be reviewed
          for compliance with the Code. Those persons also may be required under
          certain circumstances to forfeit their profits made from personal
          trading.



          The provisions of the Code are administered by and subject to
          exceptions authorized by Janus Capital.


                                                                              13

Custodian, transfer agent and certain affiliations

          Citibank, N.A., 111 Wall Street, 24th Floor, Zone 5, New York, NY
          10043, is the Portfolio's custodian. The custodian holds the
          Portfolio's assets in safekeeping and collects and remits the income
          thereon, subject to the instructions of the Portfolio.

          Janus Service Corporation, P.O. Box 173375, Denver, Colorado
          80217-3375, a wholly-owned subsidiary of Janus Capital, is the
          Portfolio's transfer agent. In addition, Janus Service provides
          certain other administrative, recordkeeping and shareholder relations
          services to the Portfolio. Janus Service is not compensated for its
          services related to the Shares, except for out-of-pocket costs.

          Janus Distributors, Inc. ("Janus Distributors"), 100 Fillmore Street,
          Denver, Colorado 80206-4928, a wholly-owned subsidiary of Janus
          Capital, is a distributor of the Portfolio. Janus Distributors is
          registered as a broker-dealer under the Securities Exchange Act of
          1934 (the "Exchange Act") and is a member of the National Association
          of Securities Dealers, Inc.


          The Portfolio pays DST Systems, Inc., a subsidiary of KCSI, license
          fees at the annual rate of $3.98 per shareholder account for the use
          of DST's shareholder accounting system. The Portfolio also pays DST
          $1.10 per closed shareholder account. The Portfolio pays DST for the
          use of its portfolio and fund accounting system a monthly base fee of
          $250 to $1,250 per month based on the number of Janus funds using the
          system and an asset charge of $1 per million dollars of net assets
          (not to exceed $500 per month).


          The Trustees have authorized the Portfolio to use another affiliate of
          DST as introducing broker for certain Portfolio transactions as a
          means to reduce Portfolio expenses through credits against the charges
          of DST and its affiliates with regard to commissions earned by such
          affiliate. See "Portfolio Transactions and Brokerage."

Portfolio transactions and brokerage

          Decisions as to the assignment of portfolio business for the Portfolio
          and negotiation of its commission rates are made by Janus Capital
          whose policy is to obtain the "best execution" (prompt and reliable
          execution at the most favorable security price) of all portfolio
          transactions.

          In selecting brokers and dealers and in negotiating commissions, Janus
          Capital considers a number of factors, including but not limited to:
          Janus Capital's knowledge of currently available negotiated commission
          rates or prices of securities currently available and other current
          transaction costs; the nature of the security being traded; the size
          and type of the transaction; the nature and character of the markets
          for the security to be purchased or sold; the desired timing of the
          trade; the activity existing and expected in the market for the
          particular security; confidentiality; the quality of the execution,
          clearance and settlement services; financial stability of the broker
          or dealer; the existence of actual or apparent operational problems of
          any broker or dealer; and research products or services provided. In
          recognition of the value of the foregoing factors, Janus Capital may
          place portfolio transactions with a broker or dealer with whom it has
          negotiated a commission that is in excess of the commission another
          broker or dealer would have charged for effecting that transaction if
          Janus Capital determines in good faith that such amount of commission
          was reasonable in relation to the value of the brokerage and research
          provided by such broker or dealer viewed in terms of either that
          particular transaction or of the overall responsibilities of Janus
          Capital. These research and other services may include, but are not
          limited to, general economic and security market reviews, industry and
          company reviews, evaluations of securities, recommendations as to the
          purchase and sale of securities, and access to third party
          publications, computer and electronic equipment and software. Research
          received from brokers or dealers is supplemental to Janus Capital's
          own research efforts.


          For the fiscal years ended December 31, 1999, December 31, 1998 and
          December 31, 1997, the Portfolio did not incur any brokerage
          commissions. The Portfolio generally buys and sells securities in
          principal and agency transactions in which no commissions are paid.
          However, the Portfolio may engage an agent and pay commissions for
          such transactions if Janus Capital believes that the net result of the
          transaction to the Portfolio will be no less favorable than that of
          contemporaneously available principal transactions.


          Janus Capital may use research products and services in servicing
          other accounts in addition to the Portfolio. If Janus Capital
          determines that any research product or service has a mixed use, such
          that it also serves functions that do not assist in the investment
          decision-making process, Janus Capital may allocate the costs of such
          service or product accordingly. Only that portion of the product or
          service that Janus Capital determines will assist it in the investment
          decision-making process may be paid for in brokerage commission
          dollars. Such allocation may create a conflict of interest for Janus
          Capital.

          Janus Capital may consider sales of Portfolio shares or shares of
          other Janus funds by a broker-dealer or the recommendation of a
          broker-dealer to its customers that they purchase such shares as a
          factor in the selection of broker-dealers to execute Portfolio
          transactions. Janus Capital may also consider payments made by brokers
          effecting transactions for a Portfolio i) to the Portfolio or ii) to
          other persons on behalf of the Portfolio for services provided to the
          Portfolio for which it would be obligated to pay. In placing portfolio
          business with such broker-dealers, Janus Capital will seek the best
          execution of each transaction.

          When the Portfolio purchases or sells a security in the
          over-the-counter market, the transaction takes place directly with a
          principal market-maker, without the use of a broker, except in those
          circumstances where in the opinion of Janus Capital better prices and
          executions will be achieved through the use of a broker.

                                                                              15

          Portfolio's objective, policies and techniques. The Trustees also
          supervise the operation of the Portfolio by its officers and review
          the investment decisions of the officers although they do not actively
          participate on a regular basis in making such decisions.

          The Trust's Executive Committee shall have and may exercise all the
          powers and authority of the Trustees except for matters requiring
          action by all Trustees pursuant to the Trust's Bylaws or Trust
          Instrument, Delaware law or the 1940 Act.

          The Money Market Funds Committee, consisting of Messrs. Loo, Mullen
          and Rothe, monitors the compliance with policies and procedures
          adopted particularly for money market funds.

          Trustee by the Portfolio and all funds advised and sponsored by Janus
          Capital (collectively, the "Janus Funds") for the periods indicated.

Purchase of Shares

          Shares of the Portfolio can be purchased only by (i) the separate
          accounts of participating insurance companies for the purpose of
          funding variable insurance contracts and (ii) qualified plans.
          Participating insurance companies and certain designated organizations
          are authorized to receive purchase orders on the Portfolio's behalf,
          and those organizations are authorized to designate their agents and
          affiliates as intermediaries to receive purchase orders. Purchase
          orders are deemed received by the Portfolio when authorized
          organizations, their agents or affiliates receive the order. The
          Portfolio is not responsible for the failure of any designated
          organization or its agents or affiliates to carry out its obligations
          to its customers. Shares of the Portfolio are purchased at the NAV per
          share as determined at the close of regular trading session of the New
          York Stock Exchange next occurring after a purchase order is received
          and accepted by the Portfolio or its authorized agent. In order to
          receive a day's dividend, your order must be received by the close of
          the regular trading session of the NYSE. The prospectus for your
          insurance company's separate account or your plan documents contain
          detailed information about investing in the Portfolio.

                                                                              21

Distribution and Shareholder Servicing plan

          Under a distribution and shareholder servicing plan ("Plan") adopted
          in accordance with Rule 12b-1 under the Investment Company Act of 1940
          (the "1940 Act"), the Shares may pay Janus Distributors, Inc., the
          Trust's distributor, a fee at an annual rate of up to 0.25% of the
          average daily net assets of the Shares of the Portfolio. Under the
          terms of the Plan, the Trust is authorized to make payments to Janus
          Distributors for remittance to insurance companies and qualified plan
          service providers as compensation for distribution and shareholder
          servicing performed by such service providers. The Plan is a
          compensation type plan and permits the payment at an annual rate of up
          to 0.25% of the average daily net assets of the Shares of a Portfolio
          for recordkeeping and administrative services as well as activities
          which are primarily intended to result in sales of the Shares,
          including but not limited to preparing, printing and distributing
          prospectuses, Statements of Additional Information, shareholder
          reports, and educational materials to prospective and existing
          contract owners and plan participants; responding to inquiries by
          contract owners and plan participants; receiving and answering
          correspondence; contract owner and participant level recordkeeping and
          administrative services; and similar activities. On December 14, 1999,
          Trustees unanimously approved the Plan which became effective on that
          date. The Plan and any Rule 12b-1 related agreement that is entered
          into by the Portfolio or Janus Distributors in connection with the
          Plan will continue in effect for a period of more than one year only
          so long as continuance is specifically approved at least annually by a
          vote of a majority of the Trustees, and of a majority of the Trustees
          who are not interested persons (as defined in the 1940 Act) of the
          Trust and who have no direct or indirect financial interest in the
          operation of the Plan or any related agreements ("12b-1 Trustees").
          All material amendments to the Plan must be approved by a majority
          vote of the Trustees, including a majority of the 12b-1 Trustees, at a
          meeting called for that purpose. In addition, the Plan may be
          terminated at any time, without penalty, by vote of a majority of the
          outstanding Shares of the Portfolio or by vote of a majority of 12b-1
          Trustees.

Redemption of Shares


          Redemptions, like purchases, may only be effected through the separate
          accounts of participating insurance companies or qualified plans.
          Certain designated organizations are authorized to receive redemption
          orders on the Portfolio's behalf and those organizations are
          authorized to designate their agents and affiliates as intermediaries
          to receive redemption orders. Redemption orders are deemed received by
          the Portfolio when authorized organizations, their agents or
          affiliates receive the order. The Portfolio is not responsible for the
          failure of any designated organization or its agents or affiliates to
          carry out its obligations to its customers. Shares normally will be
          redeemed for cash, although the Portfolio retains the right to redeem
          some or all of its shares in kind under unusual circumstances, in
          order to protect the interests of remaining shareholders, or to
          accommodate a request by a particular shareholder that does not
          adversely affect the interest of the remaining shareholders by
          delivery of securities selected from its assets at its discretion.
          However, the Portfolio is governed by Rule 18f-1 under the 1940 Act,
          which requires the Portfolio to redeem shares solely in cash up to the
          lesser of $250,000 or 1% of the net asset value of the Portfolio
          during any 90-day period for any one shareholder. Should redemptions
          by any shareholder exceed such limitation, their Portfolio will have
          the option of redeeming the excess in cash or in kind. If shares are
          redeemed in kind, the redeeming shareholder might incur brokerage
          costs in converting the assets to cash. The method of valuing
          securities used to make redemptions in kind will be the same as the
          method of valuing portfolio securities described under "Determination
          of Net Asset Value" and such valuation will be made as of the same
          time the redemption price is determined.


          The right to require the Portfolio to redeem its shares may be
          suspended, or the date of payment may be postponed, whenever (1)
          trading on the NYSE is restricted, as determined by the SEC, or the
          NYSE is closed except for holidays and weekends, (2) the SEC permits
          such suspension and so orders, or (3) an emergency exists as
          determined by the SEC so that disposal of securities or determination
          of NAV is not reasonably practicable.

                                                                              23
<PAGE>
Dividends and tax status

          Dividends representing substantially all of the net investment income
          and any net realized gains on sales of securities are declared daily,
          Saturdays, Sundays and holidays included, and distributed on the last
          business day of each month. If a month begins on a Saturday, Sunday,
          or holiday, dividends for those days are declared at the end of the
          preceding month and distributed on the first business day of the
          month. The Portfolio intends to qualify as a regulated investment
          company by satisfying certain requirements prescribed by Subchapter M
          of the Code. In addition, because a class of shares of the Portfolio
          are sold in connection with variable insurance contracts, the
          Portfolio intends to comply with the diversification requirements of
          Internal Revenue Code Section 817(h) related to the tax-deferred
          status of insurance company separate accounts.

          All income dividends on the Portfolio's Shares are reinvested
          automatically in additional Shares of the Portfolio at the NAV
          determined on the first business day following the record date.

          Because Shares of the Portfolio can only be purchased through variable
          insurance contracts or qualified plans, it is anticipated that any
          income dividends or capital gains distributions will be exempt from
          current taxation if left to accumulate within such plans. See the
          prospectus for the separate account of the related insurance company
          or the plan documents for additional information.

Principal shareholders



          The officers and Trustees of the Portfolio cannot directly own Shares
          of the Portfolio without purchasing an insurance contract through one
          of the participating insurance companies or through a qualified plan.
          As a result, such officers and Trustees as a group own less than 1% of
          the outstanding Shares of the Portfolio. As of April 3, 2000, all of
          the outstanding Shares of the Portfolio were owned by certain
          insurance company separate accounts, qualified plans and by Janus
          Capital, which provided seed capital for the Portfolio. None of the
          separate accounts or qualified plans owned more than 5% of the Shares
          of the Portfolio.


                                                                              25

Miscellaneous information


          The Portfolio is an open-end management investment company registered
          under the 1940 Act as a series of the Trust, which was organized as a
          Delaware business trust on May 20, 1993. The Trust Instrument permits
          the Trustees to issue an unlimited number of shares of beneficial
          interest from an unlimited number of series and classes of shares. As
          of the date of this SAI, the Trust consists of fourteen series of
          shares, known as "portfolios," in two or three classes. Additional
          series and/or classes may be created from time to time.


SHARES OF THE TRUST

          The Trust is authorized to issue an unlimited number of shares of
          beneficial interest with a par value of $0.001 per share for each
          series of the Trust. Shares of each series of the Trust are fully paid
          and nonassessable when issued. The Shares of the Portfolio participate
          equally in dividends and other distributions by the Portfolio, and in
          residual assets of the Portfolio in the event of liquidation. Shares
          of the Portfolio have no preemptive, conversion or subscription
          rights.


          The Portfolio currently offers two or three classes of shares. The
          Shares discussed in this SAI are offered only in connection with
          investment in and payments under variable insurance contracts and to
          qualified retirement plans that require a fee from Portfolio assets to
          procure distribution and administrative services to contract owners
          and plan participants. A second class of shares, Retirement Shares, is
          offered only to qualified plans whose service providers require a fee
          from Trust assets for providing certain services to plan participants.
          The third class of shares, Institutional Shares, are offered only in
          connection with investment in and payments under variable contracts
          and life insurance contracts, as well as certain qualified retirement
          plans.


SHAREHOLDER MEETINGS

          The Trust does not intend to hold annual shareholder meetings.
          However, special meetings may be called for the Portfolio or for the
          Trust as a whole for purposes such as electing or removing Trustees,
          terminating or reorganizing the Trust, changing fundamental policies,
          or for any other purpose requiring a shareholder vote under the 1940
          Act. Separate votes are taken by each Portfolio or class only if a
          matter affects or requires the vote of only that Portfolio or class or
          that Portfolio's or class' interest in the matter differs from the
          interest of the other portfolios or class of the Trust. A shareholder
          is entitled to one vote for each Share owned.

VOTING RIGHTS

          A participating insurance company issuing a variable insurance
          contract will vote shares in the separate account as required by law
          and interpretations thereof, as may be amended or changed from time to
          time. In accordance with current law and interpretations, a
          participating insurance company is required to request voting
          instructions from policy owners and must vote shares in the separate
          account, including shares for which no instructions have been
          received, in proportion to the voting instructions received.
          Additional information may be found in the participating insurance
          company's separate account prospectus.

          The Trustees are responsible for major decisions relating to the
          Portfolio's policies and objectives; the Trustees oversee the
          operation of the Portfolio by its officers.

          The present Trustees were elected by the initial trustee of the Trust
          on May 25, 1993, and were approved by the initial shareholder on May
          25, 1993 with the exception of Mr. Craig and Mr. Rothe who were
          appointed by the Trustees as of June 30, 1995 and as of January 1,
          1997, respectively. Under the Trust Instrument, each Trustee will
          continue in office until the termination of the Trust or his earlier
          death, retirement, resignation, bankruptcy, incapacity or removal.
          Vacancies will be filled by a majority of the

          remaining Trustees, subject to the 1940 Act. Therefore, no annual or
          regular meetings of shareholders normally will be held, unless
          otherwise required by the Trust Instrument or the 1940 Act. Subject to
          the foregoing, shareholders have the power to vote to elect or remove
          Trustees, to terminate or reorganize the Portfolio, to amend the Trust
          Instrument, to bring certain derivative actions and on any other
          matters on which a shareholder vote is required by the 1940 Act, the
          Trust Instrument, the Trust's Bylaws or the Trustees.

          As mentioned in "Shareholder Meetings", each share of each portfolio
          of the Trust has one vote (and fractional votes for fractional
          shares). Shares of all portfolios of the Trust have noncumulative
          voting rights, which means that the holders of more than 50% of the
          shares of all portfolios of the Trust voting for the election of
          Trustees can elect 100% of the Trustees if they choose to do so and,
          in such event, the holders of the remaining shares will not be able to
          elect any Trustees. Each portfolio or class of the Trust will vote
          separately only with respect to those matters that affect only that
          portfolio or class or if an interest of a portfolio or class in the
          matter differs from the interests of other portfolios or classes of
          the Trust.

Appendix A

DESCRIPTION OF SECURITIES RATINGS

Moody's and Standard & Poor's

          MUNICIPAL AND CORPORATE BONDS AND MUNICIPAL LOANS

          The two highest ratings of Standard & Poor's Ratings Services ("S&P")
          for municipal and corporate bonds are AAA and AA. Bonds rated AAA have
          the highest rating assigned by S&P to a debt obligation. Capacity to
          pay interest and repay principal is extremely strong. Bonds rated AA
          have a very strong capacity to pay interest and repay principal and
          differ from the highest rated issues only in a small degree. The AA
          rating may be modified by the addition of a plus (+) or minus (-) sign
          to show relative standing within that rating category.

          The two highest ratings of Moody's Investors Service, Inc. ("Moody's")
          for municipal and corporate bonds are Aaa and Aa. Bonds rated Aaa are
          judged by Moody's to be of the best quality. Bonds rated Aa are judged
          to be of high quality by all standards. Together with the Aaa group,
          they comprise what are generally known as high-grade bonds. Moody's
          states that Aa bonds are rated lower than the best bonds because
          margins of protection or other elements make long-term risks appear
          somewhat larger than Aaa securities. The generic rating Aa may be
          modified by the addition of the numerals 1, 2 or 3. The modifier 1
          indicates that the security ranks in the higher end of the Aa rating
          category; the modifier 2 indicates a mid-range ranking; and the
          modifier 3 indicates that the issue ranks in the lower end of such
          rating category.

          SHORT TERM MUNICIPAL LOANS

          S&P's highest rating for short-term municipal loans is SP-1. S&P
          states that short-term municipal securities bearing the SP-1
          designation have a strong capacity to pay principal and interest.
          Those issues rated SP-1 which are determined to possess a very strong
          capacity to pay debt service will be given a plus (+) designation.
          Issues rated SP-2 have satisfactory capacity to pay principal and
          interest with some vulnerability to adverse financial and economic
          changes over the term of the notes.

          Moody's highest rating for short-term municipal loans is MIG-1/VMIG-1.
          Moody's states that short-term municipal securities rated MIG-1/VMIG-1
          are of the best quality, enjoying strong protection from established
          cash flows of funds for their servicing or from established and
          broad-based access to the market for refinancing, or both. Loans
          bearing the MIG-2/VMIG-2 designation are of high quality, with margins
          of protection ample although not so large as in the MIG-1/VMIG-1
          group.

          OTHER SHORT-TERM DEBT SECURITIES

          Prime-1 and Prime-2 are the two highest ratings assigned by Moody's
          for other short-term debt securities and commercial paper, and A-1 and
          A-2 are the two highest ratings for commercial paper assigned by S&P.
          Moody's uses the numbers 1, 2 and 3 to denote relative strength within
          its highest classification of Prime, while S&P uses the numbers 1, 2
          and 3 to denote relative strength within its highest classification of
          A. Issuers rated Prime-1 by Moody's have a superior ability for
          repayment of senior short-term debt obligations and have many of the
          following characteristics: leading market positions in
          well-established industries, high rates of return on funds employed,
          conservative capitalization structure with moderate reliance on debt
          and ample asset protection, broad margins in earnings coverage of
          fixed financial charges and high internal cash generation, and well
          established access to a range of financial markets and assured sources
          of alternate liquidity. Issuers rated Prime-2 by Moody's have a strong
          ability for repayment of senior short-term debt obligations and
          display many of the same characteristics displayed by issuers rated
          Prime-1, but to a lesser degree. Issuers rated A-1 by S&P carry a
          strong degree of safety regarding timely

                                                                              29
<PAGE>

          repayment. Those issues determined to possess extremely strong safety
          characteristics are denoted with a plus (+) designation. Issuers rated
          A-2 by S&P carry a satisfactory degree of safety regarding timely
          repayment.

                                             the margin of safety is not as great as the F-1+ and F-1

                Duff 1...................... Very high certainty of timely payment. Liquidity factors are
                                             excellent and supported by good fundamental protection
                                             factors. Risk factors are minor.
                Duff 1-..................... High certainty of timely payment. Liquidity factors are
                                             strong and supported by good fundamental protection factors.

                                             external) than obligations with higher ratings, capacity to
                                             service principal and interest in a timely fashion is
                                             considered adequate.
                TBW-4....................... The lowest rating category; this rating is regarded as
                                             non-investment grade and therefore speculative.

Appendix B

DESCRIPTION OF MUNICIPAL SECURITIES

          MUNICIPAL NOTES generally are used to provide for short-term capital
          needs and usually have maturities of one year or less. They include
          the following:

          1. Project Notes, which carry a U.S. government guarantee, are issued
          by public bodies (called "local issuing agencies") created under the
          laws of a state, territory, or U.S. possession. They have maturities
          that range up to one year from the date of issuance. Project Notes are
          backed by an agreement between the local issuing agency and the
          Federal Department of Housing and Urban Development. These Notes
          provide financing for a wide range of financial assistance programs
          for housing, redevelopment, and related needs (such as low-income
          housing programs and renewal programs).

          2. Tax Anticipation Notes are issued to finance working capital needs
          of municipalities. Generally, they are issued in anticipation of
          various seasonal tax revenues, such as income, sales, use and business
          taxes, and are payable from these specific future taxes.

          3. Revenue Anticipation Notes are issued in expectation of receipt of
          other types of revenues, such as Federal revenues available under the
          Federal Revenue Sharing Programs.

          4. Bond Anticipation Notes are issued to provide interim financing
          until long-term financing can be arranged. In most cases, the
          long-term bonds then provide the money for the repayment of the Notes.

          5. Construction Loan Notes are sold to provide construction financing.
          After successful completion and acceptance, many projects receive
          permanent financing through the Federal Housing Administration under
          the Federal National Mortgage Association ("Fannie Mae") or the
          Government National Mortgage Association ("Ginnie Mae").

          6. Tax-Exempt Commercial Paper is a short-term obligation with a
          stated maturity of 365 days or less. It is issued by agencies of state
          and local governments to finance seasonal working capital needs or as
          short-term financing in anticipation of longer term financing.

          MUNICIPAL BONDS, which meet longer term capital needs and generally
          have maturities of more than one year when issued, have three
          principal classifications:

          1. General Obligation Bonds are issued by such entities as states,
          counties, cities, towns, and regional districts. The proceeds of these
          obligations are used to fund a wide range of public projects,
          including construction or improvement of schools, highways and roads,
          and water and sewer systems. The basic security behind General
          Obligation Bonds is the issuer's pledge of its full faith and credit
          and taxing power for the payment of principal and interest. The taxes
          that can be levied for the payment of debt service may be limited or
          unlimited as to the rate or amount of special assessments.

          2. Revenue Bonds in recent years have come to include an increasingly
          wide variety of types of municipal obligations. As with other kinds of
          municipal obligations, the issuers of revenue bonds may consist of
          virtually any form of state or local governmental entity, including
          states, state agencies, cities, counties, authorities of various
          kinds, such as public housing or redevelopment authorities, and
          special districts, such as water, sewer or sanitary districts.
          Generally, revenue bonds are secured by the revenues or net revenues
          derived from a particular facility, group of facilities, or, in some
          cases, the proceeds of a special excise or other specific revenue
          source. Revenue bonds are issued to finance a wide variety of capital
          projects including electric, gas, water and sewer systems; highways,
          bridges, and tunnels; port and airport facilities; colleges and
          universities; and hospitals. Many of these bonds provide additional
          security in the form of a debt service reserve fund to be used to make
          principal and interest payments. Various forms of credit enhancement,
          such as a bank letter of credit or municipal bond insurance, may also
          be employed in revenue bond issues. Housing authorities have a wide
          range of security, including partially or fully insured mortgages,
          rent subsidized and/or collateralized mortgages, and/or the net
          revenues from housing or other

                                                                              31
<PAGE>

          public projects. Some authorities provide further security in the form
          of a state's ability (without obligation) to make up deficiencies in
          the debt service reserve fund.

          In recent years, revenue bonds have been issued in large volumes for
          projects that are privately owned and operated (see 3 below).

          3. Private Activity Bonds are considered municipal bonds if the
          interest paid thereon is exempt from Federal income tax and are issued
          by or on behalf of public authorities to raise money to finance
          various privately operated facilities for business and manufacturing,
          housing and health. These bonds are also used to finance public
          facilities such as airports, mass transit systems and ports. The
          payment of the principal and interest on such bonds is dependent
          solely on the ability of the facility's user to meet its financial
          obligations and the pledge, if any, of real and personal property as
          security for such payment.

          While, at one time, the pertinent provisions of the Internal Revenue
          Code permitted private activity bonds to bear tax-exempt interest in
          connection with virtually any type of commercial or industrial project
          (subject to various restrictions as to authorized costs, size
          limitations, state per capita volume restrictions, and other matters),
          the types of qualifying projects under the Code have become
          increasingly limited, particularly since the enactment of the Tax
          Reform Act of 1986. Under current provisions of the Code, tax-exempt
          financing remains available, under prescribed conditions, for certain
          privately owned and operated rental multi-family housing facilities,
          nonprofit hospital and nursing home projects, airports, docks and
          wharves, mass commuting facilities and solid waste disposal projects,
          among others, and for the refunding (that is, the tax-exempt
          refinancing) of various kinds of other private commercial projects
          originally financed with tax-exempt bonds. In future years, the types
          of projects qualifying under the Code for tax-exempt financing are
          expected to become increasingly limited.

          Because of terminology formerly used in the Internal Revenue Code,
          virtually any form of private activity bond may still be referred to
          as an "industrial development bond," but more and more frequently
          revenue bonds have become classified according to the particular type
          of facility being financed, such as hospital revenue bonds, nursing
          home revenue bonds, multi-family housing revenues bonds, single family
          housing revenue bonds, industrial development revenue bonds, solid
          waste resource recovery revenue bonds, and so on.

          OTHER MUNICIPAL OBLIGATIONS, incurred for a variety of financing
          purposes, include: municipal leases, which may take the form of a
          lease or an installment purchase or conditional sale contract, are
          issued by state and local governments and authorities to acquire a
          wide variety of equipment and facilities such as fire and sanitation
          vehicles, telecommunications equipment and other capital assets.
          Municipal leases frequently have special risks not normally associated
          with general obligation or revenue bonds. Leases and installment
          purchase or conditional sale contracts (which normally provide for
          title to the leased asset to pass eventually to the government issuer)
          have evolved as a means for governmental issuers to acquire property
          and equipment without meeting the constitutional and statutory
          requirements for the issuance of debt. The debt-issuance limitations
          of many state constitutions and statutes are deemed to be inapplicable
          because of the inclusion in many leases or contracts of
          "non-appropriation" clauses that provide that the governmental issuer
          has no obligation to make future payments under the lease or contract
          unless money is appropriated for such purpose by the appropriate
          legislative body on a yearly or other periodic basis. To reduce this
          risk, the Fund will only purchase municipal leases subject to a
          non-appropriation clause when the payment of principal and accrued
          interest is backed by an unconditional irrevocable letter of credit,
          or guarantee of a bank or other entity that meets the criteria
          described in the Prospectus.

          Tax-exempt bonds are also categorized according to whether the
          interest is or is not includible in the calculation of alternative
          minimum taxes imposed on individuals, according to whether the costs
          of acquiring or carrying the bonds are or are not deductible in part
          by banks and other financial institutions, and according to other
          criteria relevant for Federal income tax purposes. Due to the
          increasing complexity of Internal Revenue Code and related
          requirements governing the issuance of tax-exempt bonds, industry
          practice has uniformly required, as a condition to the issuance of
          such bonds, but particularly for revenue bonds, an opinion of
          nationally recognized bond counsel as to the tax-exempt status of
          interest on the bonds.

                                                                              33

ITEM 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT

         None

ITEM 25. INDEMNIFICATION

     Article IX of Janus Aspen Series' Trust Instrument provides for
indemnification of certain persons acting on behalf of the Portfolios. In
general, Trustees and officers will be indemnified against liability and against
all expenses of litigation incurred by them in connection with any
<PAGE>

claim, action, suit or proceeding (or settlement of the same) in which they
become involved by virtue of their office in connection with the Portfolios,
unless their conduct is determined to constitute willful misfeasance, bad faith,
gross negligence or reckless disregard of their duties, or unless it has been
determined that they have not acted in good faith in the reasonable belief that
their actions were in the best interests of the Portfolios. A determination that
a person covered by the indemnification provisions is entitled to
indemnification may be made by the court or other body before which the
proceeding is brought, or by either a vote of a majority of a quorum of Trustees
who are neither "interested persons" of the Trust nor parties to the proceeding
or by an independent legal counsel in a written opinion. The Portfolios also may
advance money for these expenses, provided that the Trustee or officer
undertakes to repay the Portfolios if his conduct is later determined to
preclude indemnification, and that either he provide security for the
undertaking, the Trust be insured against losses resulting from lawful advances
or a majority of a quorum of disinterested Trustees, or independent counsel in a
written opinion, determines that he ultimately will be found to be entitled to
indemnification. The Trust also maintains a liability insurance policy covering
its Trustees and officers.

     Amendment dated April 3, 2000, to the custody contract, dated September 13,
1993,  as amended,  by and between  State  Street  Bank and Trust  Company  (the

initialed by two or more  persons as the Board of Trustees  shall have from time
to time authorized.  Each such writing shall set forth the specific  transaction
or type of transaction  involved,  including a specific statement of the purpose

Instructions if the Custodian  reasonably  believed them to have been given by a
person  authorized  to give such  instructions  with respect to the  transaction
involved. The Fund shall cause all oral instructions to be confirmed in writing.
Proper  Instructions  may  include  communications   effected  directly  between
electro-mechanical  or electronic  devices;  provided that the Fund has followed

                         CONFIDENCE WITH EVERY ACTION"

- --------------------------------------------------------------------------------
                                  DEFINITIONS

- --------------------------------------------------------------------------------

The following definitions are used throughout this document. You are responsible
for reading and being familiar with each definition.

          the  purchase  or sale of  securities  for the Janus  Funds or for the
          advisory  clients or whose functions or duties as part of the ordinary
          course  of  his  or  her   business   relate  to  the  making  of  any
          recommendation  to the Janus Funds or advisory  clients  regarding the
          purchase or sale of securities; and

     3)   Any other persons  designated by the Ethics Committee as having access
          to current trading information.

2.       "Advisory Person" shall mean:

     1)   ANY EMPLOYEE OF THE JANUS FUNDS OR JCC (OR OF ANY COMPANY IN A CONTROL
          relationship  to the Janus Funds or JCC) who in connection with his or
          her regular  functions or duties,  makes,  participates  in or obtains
          information  regarding the purchase or sale of a security by the Funds
          or for the account of advisory  clients,  or whose functions relate to
          the making of any  recommendations  with respect to such purchases and

     2)   Any natural person in a control  relationship  to the Funds or JCC who

     "Beneficial  Ownership" encompasses securities held in the name of a spouse

     including an instrument whose value is derived or based on any of the above
     (a "derivative"). The term Covered Security includes any separate security,

- --------------------------------------------------------------------------------
                                  INTRODUCTION

- --------------------------------------------------------------------------------

     These Ethics Rules ("Rules") apply to all Covered Persons.  The Rules apply
to  transactions  for  your  personal   accounts  and  any  other  accounts  you
Beneficially Own. You may be deemed the beneficial owner of any account in which
you have a direct or indirect financial interest.  Such accounts include,  among
others,  accounts  held in the  name  of  your  spouse  or  equivalent  domestic
partnership,  your minor  children,  a relative  sharing  your home,  or certain
trusts under which you or such persons are a beneficiary.

     The Rules are  intended to ensure that you (i) at all times place first the
interests of the Janus  Funds,  investment  companies  for which Janus serves as
subadviser,  and other advisory clients  ("Clients");  (ii) conduct all personal
trading consistent with the Rules and in such a manner as to avoid any actual or
potential  conflict  of  interest  or any  abuse of your  position  of trust and
responsibility;  and  (iii)  not  use  any  material  nonpublic  information  in
securities  trading.  The Rules also establish policies regarding other matters,
such as outside employment and the giving or receiving of gifts.

     You are  required to read and retain these Rules and to sign and return the
attached  Acknowledgment  of Receipt Form to  Compliance  upon  commencement  of
employment  or  other  services.  On an  annual  basis  thereafter,  you will be
required to complete an Annual Certification Form. The Annual Certification Form
confirms that (i) you have received,  read and asked any questions  necessary to
understand the Rules;  (ii) you agree to conduct yourself in accordance with the
Rules;  and (iii) you have  complied with the Rules during such time as you have
been  associated  with Janus.  Depending on your status,  you may be required to
submit  additional  reports  and/or obtain  clearances  as discussed  more fully
below.

     Unless otherwise defined, all capitalized terms shall have the same meaning
as set forth in the Definitions section.

                  CAUTION REGARDING PERSONAL TRADING ACTIVITIES

     Certain  personal  trading  activities may be risky not only because of the
nature of the  transactions,  but also because  action  necessary to close out a
position  may become  prohibited  for some  Covered  Persons  while the position
remains  open.  For  example,  you may not be able to close out short  sales and
transactions  in  derivatives.  Furthermore,  if JCC  becomes  aware of material
nonpublic  information,  or if a Client  is  active  in a given  security,  some
Covered  Persons may find themselves  "frozen" in a position.  JCC will not bear
any losses in personal accounts resulting from the application of these Rules.

                 COMMUNICATIONS WITH OUTSIDE TRUSTEES/DIRECTORS

     As a regular business practice, JCC attempts to keep Directors and Trustees
informed with respect to its  investment  activities  through  reports and other
information provided to them in connection with board meetings and other events.
In  addition,  Janus  personnel  are  encouraged  to respond to  inquiries  from
Directors  and  Trustees,  particularly  as  they  relate  to  general  strategy
considerations or economic or market conditions affecting Janus.  However, it is
JCC's policy not to communicate  specific trading  information  and/or advice on
specific issues to Outside  Directors and Outside Trustees (i.e., no information
should be given on securities for which current activity is being considered for
Clients).  Any pattern of repeated requests by such Directors or Trustees should
be reported to the Chief Compliance Officer or the Compliance Manager.

                                 CODE OF ETHICS
- --------------------------------------------------------------------------------

                                    OVERVIEW

     In  general,   it  is  unlawful  for  persons  affiliated  with  investment
companies,  their principal  underwriters or their investment advisers to engage
in personal  transactions  in securities  held or to be acquired by a registered
investment company,  if such personal  transactions are made in contravention of
rules  which  the  SEC  has  adopted  to  prevent   fraudulent,   deceptive  and
manipulative  practices.  Such rules require each registered investment company,
investment  adviser and principal  underwriter  to adopt its own written code of
ethics containing  provisions reasonably necessary to prevent its employees from
engaging in such conduct, and to maintain records, use reasonable diligence, and
institute such procedures as are reasonably  necessary to prevent  violations of
such code. This Code of Ethics ("Code") and information  reported hereunder will
enable Janus to fulfill these requirements.

                              GENERAL PROHIBITIONS

     The following  activities are prohibited  for  applicable  Covered  Persons
(remember,  if you  work at  Janus  full-time,  part-time,  temporarily  or on a
contract  basis,  or you are a Trustee or Director,  you are a Covered  Person).
Persons  who  violate any  prohibition  may be required to disgorge  any profits
realized in connection with such violation to a charitable organization selected
by the Ethics  Committee  and may be subject to other  sanctions  imposed by the
Ethics Committee, as outlined in the Penalty Guidelines.

1.   Covered  Persons may not cause a Client to take action,  or to fail to take
     action,  for personal  benefit,  rather than to benefit  such  Client.  For
     example,  a Covered  Person would  violate this Code by causing a Client to
     purchase  a  security  owned  by the  Covered  Person  for the  purpose  of
     supporting or increasing  the price of that security or by causing a Client
     to  refrain  from  selling a  security  in an attempt to protect a personal
     investment, such as an option on that security.

2.   Covered  Persons may not use  knowledge of portfolio  transactions  made or
     contemplated  for  Clients to  profit,  or cause  others to profit,  by the
     market effect of such transactions.

3.   Covered Persons may not disclose  current  portfolio  transactions  made or
     contemplated  for  Clients as well as any other  nonpublic  information  to
     anyone outside of Janus.

4.   Covered Persons may not engage in fraudulent conduct in connection with the
     purchase  or  sale  of a  Security  Held  or to be  Acquired  by a  Client,
     including without limitation:

     1)   Employing any device, scheme or artifice to defraud any Client;

     2)   Making to any Client any untrue statement of material fact or omitting
          to state to any Client a material fact  necessary in order to make the
          statements  made, in light of the  circumstances  under which they are
          made, not misleading;

     3)   Engaging in any act,  practice or course of business which operates or
          would operate as a fraud or deceit upon any Client;

     4)   Engaging in any manipulative practice with respect to any Client; or

                                       5
<PAGE>

     5)   Investing  in  derivatives  to evade the  restrictions  of this  Code.
          Accordingly,  individuals may not use derivatives to take positions in
          securities  that  would  be  otherwise  prohibited  by the Code if the
          positions were taken directly.

5.   Investment  Personnel may not serve on the board of directors of a publicly
     traded  company  without  prior  written   authorization  from  the  Ethics
     Committee.  No such  service  shall be  approved  without a finding  by the
     Ethics Committee that the board service would not be inconsistent  with the
     interests  of  Clients.  If  board  service  is  authorized  by the  Ethics
     Committee,  the Investment Personnel serving as director normally should be
     isolated from those making investment decisions with respect to the company
     involved through "Chinese Walls" or other procedures.

                              TRADING RESTRICTIONS

     The  trading  restrictions  of the Code  apply to all  direct  or  indirect
acquisitions or dispositions of Covered Securities,  whether by purchase,  sale,
tender offers,  stock purchase plan,  gift,  inheritance,  or otherwise.  Unless
otherwise  noted,  the  following  trading  restrictions  are  applicable to any
transaction  in a  Covered  Security  Beneficially  Owned by a  Covered  Person.
Outside   Directors  and  Outside  Trustees  are  exempt  from  certain  trading
restrictions  because of their limited access to current  information  regarding
Client investments.

     Any disgorgement of profits required under any of the following  provisions
shall be donated to a charitable  organization selected by the Ethics Committee,
as outlined in the Penalty Guidelines. However, if disgorgement is required as a
result of trades by a portfolio  manager that conflicted with that manager's own
Clients,  disgorgement  proceeds  shall be paid  directly  to such  Clients.  If
disgorgement  is required  under more than one provision,  the Ethics  Committee
shall determine in its sole discretion the provision that shall control.1

EXCLUDED TRANSACTIONS

     Some or all of the trading  restrictions  listed  below do not apply to the
following  transactions;  however,  these transactions must still be reported to
Compliance (see Reporting Requirements):

     o    Tender  offer  transactions  are exempt from all trading  restrictions
          except preclearance.

- --------
         1 Unless otherwise noted,  restrictions on personal  transactions apply
to transactions involving Covered Securities,  including any derivative thereof.
When  determining  the  amount  of  disgorgement  required  with  respect  to  a
derivative,  consideration  will be  given  to  price  differences  in both  the
derivative and the underlying securities,  with the lesser amount being used for
purposes  of  computing  disgorgement.   For  example,  in  determining  whether
reimbursement is required when the applicable  personal trade is in a derivative
and the Client  transaction is in the underlying  security,  the amount shall be
calculated  using the  lesser of (a) the  difference  between  the price paid or
received for the  derivative  and the closing bid or ask price (as  appropriate)
for the derivative on the date of the Client transaction,  or (b) the difference
between the last sale price,  or the last bid or ask price (as  appropriate)  of
the underlying security on the date of the derivative transaction, and the price
received or paid by the Client for the underlying security. Neither preclearance
nor  disgorgement  shall be required if such person=s  transaction  is to close,
sell or exercise a derivative within five days of its expiration.

                                       6

     o    The acquisition of securities  through stock purchase plans are exempt
          from all trading restrictions except preclearance,  the trading ban on
          portfolio managers and assistant portfolio managers, and the seven day
          rule. (Note: the sales of securities acquired through a stock purchase
          plan are subject to all of the trading restrictions of the Code).

     o    The  acquisition  of  securities  through stock  dividends,  automatic
          dividend  reinvestment  plans,  stock  splits,  reverse  stock splits,
          mergers,   consolidations,   spin-offs,  or  other  similar  corporate
          reorganizations or distributions  generally  applicable to all holders
          of the same  class of such  securities  are  exempt  from all  trading
          restrictions.  The  acquisition of securities  through the EXERCISE OF
          RIGHTS  ISSUED  BY AN  ISSUER  PRO RATA to all  holders  of a class of
          securities,  to the extent the rights  were  acquired in the issue are
          exempt from all trading restrictions.

     o    Non-discretionary transactions in Company Stock (e.g., the acquisition
          of securities  through Stilwell or KCSI's Employee Stock Purchase Plan
          ("ESPP")  or the  receipt of  options  in  Company  Stock as part of a
          compensation   or   benefit   plan)  are  exempt   from  all   trading
          restrictions.  Discretionary  transactions  in Company Stock issued by
          JCC  are  exempt   from  all   trading   restrictions.   Discretionary
          transactions  in  Company  Stock  issued by  Stilwell  or KCSI  (e.g.,
          exercising  options or selling ESPP Stock) are exempt from all trading
          restrictions  except  preclearance (See procedures for Preclearance of
          Company Stock).

     o    The  acquisition  of securities by gift or  inheritance is exempt from
          all trading  restrictions.  (Note: the sales of securities acquired by
          gift or  inheritance  ARE subject to all trading  restrictions  of the
          Code).

     o    Transactions  in  options  on and  securities  based on the  following
          indexes are exempt from all trading  restrictions:  S&P 500 Index, S&P
          MidCap 400 Index, S&P 100 Index, FTSE 100 Index or Nikkei 225 Index.

DISCLOSURE OF CONFLICTS

     If an Investment  Person is planning to invest or make a recommendation  to
invest in a security  for a Client,  and such person has a material  interest in
the  security,  such  person  must first  disclose  such  interest to his or her
manager or the Chief Investment Officer.  The manager or Chief Investment Office
shall  conduct an  independent  review of the  recommendation  to  purchase  the
security for  Clients.  The manager or Chief  Investment  Officer may review the
recommendation  only if he or she has no material  interest in the  security.  A
material   interest  is   Beneficial   Ownership  of  any  security   (including
derivatives,  options, warrants or rights), offices, directorships,  significant
contracts, or interests or relationships that are likely to affect such person's
judgment.

PRECLEARANCE

     Access Persons (except Outside  Directors and Outside Trustees) must obtain
preclearance   prior  to  engaging  in  any  personal   transaction  in  Covered
Securities. (See Preclearance Procedures below).

                                       7
<PAGE>


TRADING BAN ON PORTFOLIO MANAGERS AND ASSISTANT PORTFOLIO MANAGERS

     Portfolio  managers  and  their  assistants  are  prohibited  from  trading
personally in Covered Securities.  However,  the following types of transactions
are exempt from this policy, but are subject to all applicable provisions of the
Rules, including preclearance:

     o    Purchases or sales of Company Stock;

     o    The sale of any security that is not held by any Client; and

     o    The  sale  of any  security  in  order  to  raise  capital  to  fund a
          significant life event. For example,  purchasing a home or automobile,
          or paying medical or education expenses.

BAN ON IPOs AND HOT ISSUES

     Covered  Persons (except  Outside  Directors and Outside  Trustees) may not
purchase  securities in an initial  public  offering or in a secondary  offering
that constitutes a "hot issue" as defined in NASD rules.  Such securities may be
purchased or received,  however,  where the  individual has an existing right to
purchase the security based on his or her status as an investor, policyholder or
depositor of the issuer. In addition,  securities issued in reorganizations  are
also  outside  the scope of this  prohibition  if the  transaction  involves  no
investment  decision on the part of the Covered Person except in connection with
a shareholder vote.

60 DAY RULE

     Access  Persons  (except  Outside  Directors  and Outside  Trustees)  shall
disgorge any profits realized in the purchase and sale, or sale and purchase, of
the same or equivalent  Covered  Securities within sixty (60) calendar days if a
Client held or traded the security during the sixty (60) calendar day period.

BLACKOUT PERIOD

     No Access  Person may engage in a  transaction  in a Covered  Security when
such  person  knows or should  have  known at the time there to be  pending,  on
behalf  of any  Client,  a "buy" or  "sell"  order in that  same  security.  The
existence  of  pending  orders  will be  checked  by  Compliance  as part of the
Preclearance process. Preclearance may be given when any pending Client order is
completely executed or withdrawn.

FIFTEEN DAY RULE

     Any Access Person (except Outside  Directors and Outside Trustees) who buys
or sells a Covered Security within fifteen calendar days before such security is
bought  or sold on behalf  of any  Client  must  disgorge  any  price  advantage
realized. The price advantage shall be the favorable spread, if any, between the
price paid or  received  by such  person and the least  favorable  price paid or
received by a client during such period.2 The Ethics Committee has the authority
by  unanimous  action to exempt any  person  from the  fifteen-day  rule if such
person is selling a security to raise capital to fund a significant  life event.
For example,  purchasing a home or  automobile,  or paying  medical or education
expenses. In order for the Ethics

___________________________

     2 Personal  purchases are matched only against  subsequent Client purchases
and personal sales are matched only against subsequent Client sales for purposes
of this restriction.

<PAGE>

Committee to consider  such  exemption,  the life event must occur within thirty
(30)  calendar  days of the  security  transaction,  and the person must provide
written confirmation of the event.

SEVEN DAY RULE

     Any portfolio  manager or assistant  portfolio  manager who buys or sells a
Covered  Security within seven calendar days before or after he or she trades in
that security on behalf of a Client shall disgorge any profits  realized on such
transaction.

SHORT SALES

     Any Access Person who sells short a Covered Security that such person knows
or should  have  known is held long by any  Client  shall  disgorge  any  profit
realized on such  transaction.  This prohibition  shall not apply,  however,  to
securities indices or derivatives  thereof (such as futures contracts on the S&P
500 index).  Client  ownership of Covered  Securities will be checked as part of
the Preclearance process.

HEDGE FUNDS, INVESTMENT CLUBS, AND OTHER INVESTMENTS

     No Access  Person  (except  Outside  Directors  and Outside  Trustees)  may
participate  in  hedge  funds,   partnerships,   investment  clubs,  or  similar
investment  vehicles,  unless  such  person does not have any direct or indirect
influence or control over the trading. Covered Persons wishing to rely upon this
provision must submit a Certification of  Non-Influence  and Non-Control Form to
the Compliance Manager for approval. (See Non-Influence and Non-Control Accounts
section below.)

                             PRECLEARANCE PROCEDURES

     Access Persons must obtain preclearance for all applicable  transactions in
Covered  Securities  in  which  such  person  has  a  Beneficial   Interest.   A
Preclearance  Form must be completed  and  forwarded to  Compliance.  Compliance
shall  promptly  notify the  person of  approval  or denial of the  transaction.
Notification  of approval or denial of the  transaction  may be given  verbally;
however,  it shall be  confirmed  in writing  within  seventy-two  (72) hours of
verbal  notification.  When preclearance has been approved,  the person then has
four business days from and including the day of first  notification  to execute
the trade.

GENERAL PRECLEARANCE

     General  preclearance shall be obtained from an authorized person from each
of the following three groups:

     o    A DESIGNATED LEGAL OR COMPLIANCE REPRESENTATIVE,  who will present the
          personal investment to the attendees of the weekly investment meeting,
          whereupon an opportunity  will be given to orally object.  An attendee
          of the weekly  investment  meeting  shall object to such  clearance if
          such person knows of a conflict with a pending Client transaction or a
          transaction  known by such  attendee to be under  consideration  for a
          Client.  Objections to such  clearance  should also take into account,
          among other  factors,  whether the  investment  opportunity  should be
          reserved for a Client.  If no objections  are raised,  the  Designated
          Legal or  Compliance  Representative  shall so indicate by signing the
          Preclearance  Form.  Such approval  shall not be required for sales of
          securities not held by any Clients.

                                       9
<PAGE>

         In place of this  authorization,  Investment  Personnel are required to
         obtain  approvals from all Executive  Investment  Committee  members as
         noted in the  section  below  entitled  Preclearance  Requirements  for
         Investment Personnel.

     o    A  DESIGNATED  TRADING  OPERATIONS  REPRESENTATIVE,  who  may  provide
          clearance if such  Representative  knows at the time of the request of
          no pending "buy" or "sell" order in the security on behalf of a Client
          and no such trades are known by such person to be under consideration.

     o    The  COMPLIANCE   MANAGER,   OR  A  DESIGNATED   LEGAL  OR  COMPLIANCE
          REPRESENTATIVE  IF THE COMPLIANCE  MANAGER IS NOT  AVAILABLE,  who may
          provide clearance if no legal prohibitions are known by such person to
          exist with respect to the proposed trade. Approvals for such clearance
          should take into account,  among other  factors,  the existence of any
          Watch  List  or  Restricted   List  and,  to  the  extent   reasonably
          practicable, recent trading activity and holdings of Clients.

     NO authorized  person may preclear a transaction in which such person has a
Beneficial Interest.

PRECLEARANCE REQUIREMENTS FOR INVESTMENT PERSONNEL

     Trades by Investment Personnel may not be precleared by presentation at the
weekly  investment  meeting.  Instead,  Investment  Personnel  must  obtain  the
following management  approvals.  However,  such approvals shall not be required
for sales of securities not held by any Clients:

     o    TRADES IN EQUITY  SECURITIES  require prior written  approval from all
          members of the Executive  Investment  Committee,  Investment  Person's
          manager and either Ron Speaker or Sandy Rufenacht;

     o    TRADES IN DEBT  SECURITIES  require  prior  written  approval from all
          senior fixed income portfolio managers,  either Jim Craig or two other
          Executive   Investment  Committee  members,  and  Investment  Person's
          manager.

     A portfolio manager may not preclear his or her own transaction.

PRECLEARANCE OF COMPANY STOCK

     Officers of Janus and certain persons  designated by Compliance who wish to
make discretionary  transactions in Stilwell or KCSI securities,  or derivatives
thereon, must preclear such transactions. A Company Stock Preclearance Form must
be completed and forwarded to Compliance.  Compliance  shall promptly notify the
person of approval or denial for the  transaction.  Notification  of approval or
denial for the transaction may be given verbally; however, it shall be confirmed
in  writing  within  seventy-two  (72)  hours  of  verbal   notification.   When
preclearance has been approved,  the person then has four business days from and
including the day of first notification to execute the trade.

     If such  persons  are  subject to the  provisions  of Section  16(b) of the
Securities  Exchange Act of 1934,  trading will generally be allowed only in the
ten (10) business day period beginning  seventy-two (72) hours after Stilwell or
KCSI files its  quarterly  results  with the SEC (e.g.,  10Q or 10K filing,  not
earnings  release).  To preclear the trade, the Compliance Manager or such other
Representative  shall discuss the  transaction  with Janus's  General Counsel or
Chief Financial Officer.

                                       10
<PAGE>

PRECLEARANCE OF TENDER OFFERS AND STOCK PURCHASE PLANS

     Access Persons (other than Outside Directors and Outside Trustees) who wish
to  participate  in a tender offer or stock  purchase  plan must  preclear  such
trades  only  with  the  Compliance   Manager  prior  to  submitting  notice  to
participate  in such  tender  offer or notice  of  participation  in such  stock
purchase plan to the applicable  company.  To preclear the trade, the Compliance
Manager shall consider all material factors relevant to a potential  conflict of
interest  between the Access  Person and Clients.  In addition,  any increase of
$100 or more to a pre-existing stock purchase plan must be precleared.

FOUR DAY EFFECTIVE PERIOD

     Clearances to trade will be in effect for only four  trading/business  days
from and including the date of the last Authorized Person's signature (which may
not  be  provided  more  than  one  day  after  the  first  Authorized  Person's
signature).  For tender offers, stock purchase plans,  exercise of Company Stock
and  similar  transactions,  the date the  request is  submitted  to the company
processing  the  transaction  will be considered  the trade date for purposes of
this requirement. Open orders, including stop loss orders, will generally not be
allowed  unless  such  order is  expected  to be  completed  within the four day
effective  period.  It is necessary  to  re-preclear  transactions  not executed
within the four day effective period.

                             REPORTING REQUIREMENTS

ACCOUNT STATEMENTS

     ACCESS  PERSONS (other than Outside  Trustees) and REGISTERED  PERSONS must
notify  Compliance  of each  brokerage  account in which they have a  Beneficial
Interest and must arrange for their brokers or financial institutions to provide
to Compliance, on a timely basis, duplicate account statements and confirmations
showing all transactions in brokerage or commodities accounts in which they have
a Beneficial  Interest.  A Personal  Brokerage Account Disclosure Form should be
completed for this purpose.

     PLEASE NOTE THAT, EVEN IF SUCH PERSON DOES NOT TRADE COVERED  SECURITIES IN
A PARTICULAR  BROKERAGE OR COMMODITIES ACCOUNT (E.G.,  TRADING MUTUAL FUNDS IN A
SCHWAB ACCOUNT), THE REPORTING OF DUPLICATE ACCOUNT STATEMENTS AND CONFIRMATIONS
IS STILL  REQUIRED.  HOWEVER,  IF SUCH PERSON ONLY USES A  PARTICULAR  BROKERAGE
ACCOUNT FOR CHECKING ACCOUNT PURPOSES,  AND NOT INVESTMENT  PURPOSES,  HE OR SHE
MAY IN LIEU OF REPORTING  DUPLICATE ACCOUNT  STATEMENTS,  REPORT DUPLICATE TRADE
CONFIRMATIONS AND MAKE A QUARTERLY  REPRESENTATION TO COMPLIANCE INDICATING THAT
NO INVESTMENT  TRANSACTIONS OCCURRED IN THE ACCOUNT DURING THE CALENDAR QUARTER.
Reporting of accounts that do not allow any trading in Covered Securities (e.g.,
a mutual fund account held directly with the fund sponsor) is not required.

     Covered Persons must notify  Compliance of each  reportable  account at the
time it is opened, and annually  thereafter,  including the name of the firm and
the name under  which the  account is  carried.  A  Personal  Brokerage  Account
Disclosure Form should be completed for this purpose.

     Certain  transactions  might not be reported  through a brokerage  account,
such as private  placements,  inheritances or gifts. In these instances,  Access
Persons must report these  transactions  within ten (10)  calendar  days using a
Personal Securities Transaction Report as noted below.

- --------------------------------------------------------------------------------
REGISTERED  PERSONS ARE REMINDED THAT THEY MUST ALSO INFORM ANY  BROKERAGE  FIRM
WITH WHICH THEY OPEN AN ACCOUNT,  AT THE TIME THE  ACCOUNT IS OPENED,  THAT THEY
ARE REGISTERED WITH JDI.
- --------------------------------------------------------------------------------
                                       11
<PAGE>

     NON-ACCESS  PERSONS  who  engage  in an  aggregate  of  $25,000  or more of
transactions  in  Covered   Securities  within  a  calendar  year  must  provide
Compliance with an Annual  Transaction  Report listing all such  transactions in
all accounts in which such person has a  Beneficial  Interest.  Compliance  will
request this  information  annually and will spot check all or a portion of such
transactions or accounts.

HOLDINGS REPORTS

     ACCESS PERSONS (other than Outside Trustees) must, within ten (10) calendar
days after becoming an Access Person,  provide Compliance with a Holdings Report
which lists all Covered Securities  beneficially held and any brokerage accounts
through which such  securities are  maintained.  In addition,  such persons must
provide a brief  description  of any positions  held (e.g.,  director,  officer,
other)  with  for-profit  entities  other than Janus.  The report  must  contain
information  current as of no more than thirty (30)  calendar days from the time
the report is submitted.

PERSONAL SECURITIES TRANSACTION REPORTS

     ACCESS  PERSONS  (other  than  Outside  Trustees)  must  provide a Personal
Securities  Transaction Report within ten (10) calendar days after any month end
showing all transactions in Covered Securities for which confirmations are known
by such  person  to not  have  been  timely  provided  to  Janus,  and all  such
transactions  that  are not  effected  in  brokerage  or  commodities  accounts,
including without limitation  non-brokered private placements,  and transactions
in  securities  that  are  in  certificate   form,   which  may  include  gifts,
inheritances, and other transactions in Covered Securities.

     OUTSIDE  TRUSTEES need only report a transaction  in a Covered  Security if
such person, at the time of that transaction, knew or, in the ordinary course of
fulfilling  his or her  official  duties as a Trustee  should have known,  that,
during  the  fifteen-day  period  immediately  preceding  the date of his or her
personal  transaction,  such  security  was  purchased  or sold by, or was being
considered  for  purchase  or sale on behalf  of,  any Janus Fund for which such
person acts as Trustee.

SUCH PERSONS MUST PROMPTLY COMPLY WITH ANY REQUEST OF THE COMPLIANCE  MANAGER TO
PROVIDE  TRANSACTION  REPORTS  REGARDLESS  OF  WHETHER  THEIR  BROKER  HAS  BEEN
INSTRUCTED TO PROVIDE  DUPLICATE  CONFIRMATIONS.  SUCH REPORTS MAY BE REQUESTED,
FOR EXAMPLE, TO CHECK THAT ALL APPLICABLE CONFIRMATIONS ARE BEING RECEIVED OR TO
SUPPLEMENT THE REQUESTED  CONFIRMATIONS WHERE A BROKER IS DIFFICULT TO WORK WITH
OR OTHERWISE FAILS TO PROVIDE DUPLICATE CONFIRMATIONS ON A TIMELY BASIS.

NON-INFLUENCE AND NON-CONTROL ACCOUNTS

     The  Rules  shall  not  apply  to  any  account,  partnership,  or  similar
investment  vehicle  over  which a Covered  Person  has no  direct  or  indirect
influence or control.  Covered  Persons  wishing to rely upon this provision are
required to receive approval from the Ethics Committee. In order to request such
approval,  a  Certification  of  Non-Influence  and  Non-Control  Form  must  be
submitted to the Compliance Manager.

     Any account  beneficially  owned by a Covered Person that is managed by JCC
in a discretionary capacity is not covered by these Rules so long as such person
has no direct or indirect influence or control over the account.  The employment
relationship between the account-holder and the individual managing the

                                       12
<PAGE>

account, in the absence of other facts indicating control, will not be deemed to
give such account-holder influence or control over the account.

                              OTHER REQUIRED FORMS

     In addition to the Preclearance Form,  Preclearance Form for Company Stock,
Personal Brokerage Account Disclosure Form, Holdings Report,  Report of Personal
Securities  Transactions,   Annual  Transaction  Report,  and  Certification  of
Non-Influence   and  Non-Control  Form  discussed  above,  the  following  forms
(available through Lotus Notes) must be completed if applicable to you:

ACKNOWLEDGMENT OF RECEIPT FORM

     Each  Covered  Person must provide  Compliance  with an  Acknowledgment  of
Receipt Form within ten (10)  calendar  days of  commencement  of  employment or
other  services  certifying  that he or she has  received a current  copy of the
Rules and acknowledges, as a condition of employment, that he or she will comply
with the Rules in their entirety.

ANNUAL CERTIFICATION FORM

     Each Covered  Person must provide  Compliance  annually  within thirty (30)
calendar days from date of request with an Annual  Certification Form certifying
that he or she:

     1)   Has received, read and understands the Rules;

     2)   Has complied with the requirements of the Rules; and

     3)   Has disclosed or reported all open brokerage and commodities accounts,
          personal holdings and personal securities  transactions required to be
          disclosed or reported pursuant to the requirements of the Rules.

OUTSIDE DIRECTOR/TRUSTEE REPRESENTATION FORM

     All Outside  Directors and Outside  Trustees  must,  upon  commencement  of
services  and  annually   thereafter,   provide   Compliance   with  an  Outside
Director/Trustee  Representation Form. The Form declares that such persons agree
to refrain from trading in any  securities  when they are in  possession  of any
information regarding trading recommendations made or proposed to be made to any
Client by Janus or its officers or employees.

     The  term  "insider  trading"  is not  defined  in the  federal  securities
statutes,  but  generally  is used to  refer  to the use of  material  nonpublic
information  to trade in  securities  (whether or not one is an "insider") or to
communications of material nonpublic information to others.

     While the law concerning  insider  trading can be complex and unclear,  you
should assume that the law prohibits:

     o    Trading by an  insider,  while in  possession  of  material  nonpublic
          information,

     o    Trading by a  non-insider,  while in possession of material  nonpublic
          information,  where the  information  was disclosed to the non-insider
          (either directly or through one or more  intermediaries)  in violation
          of an insider's duty to keep it confidential,

     o    Communicating  material nonpublic information to others in breach of a
          duty not to disclose such information, and

     o    Misappropriating   confidential  information  for  securities  trading
          purposes, in breach of a duty owed to the source of the information to
          keep the information confidential.

     Trading based on material  nonpublic  information  about an issuer does not
violate  this policy  unless the trader (i) is an  "insider"  with respect to an
issuer;  (ii) receives the information  from an insider or from someone that the
trader  knows  received  the  information  from an insider,  either  directly or
indirectly,  or (iii)  misappropriates  the nonpublic  information or obtains or
misuses it in breach of a duty of trust and confidence owed to the source of the
information.  Accordingly, trading based on material nonpublic information about
an issuer can be, but is not  necessarily,  a violation of this Policy.  Trading
while in possession of material nonpublic information relating to a tender offer
is prohibited under this Policy regardless of how such information was obtained.

     Application of the law of insider trading to particular transactions can be
difficult,  particularly if it involves a  determination  about trading based on
material  nonpublic  information.  You  legitimately  may be uncertain about the
application  of  this  Policy  in  particular  circumstances.  If you  have  any
questions  regarding  the  application  of the  Policy or you have any reason to
believe that a violation  of the Policy has  occurred or is about to occur,  you
should contact the Chief Compliance Officer or the Compliance Manager.

     The following  discussion is intended to help you  understand the principal
concepts involved in insider trading.

                                       14

WHO IS AN INSIDER?

     The concept of  "insider" is broad.  It includes  officers,  directors  and
employees of a company. In addition, a person can be a "temporary insider" if he
or she  enters  into a special  confidential  relationship  in the  conduct of a
company's affairs and as a result is given access to information  solely for the
company's purposes.  A temporary insider can include,  among others, a company's
attorneys, accountants, consultants, bank lending officers, and the employees of
such organizations.  In addition, one or more of the Janus entities may become a
temporary  insider  of a  company  it  advises  or for which it  performs  other
services.  To be considered an insider,  the company must expect the outsider to
keep the disclosed  nonpublic  information  confidential and/or the relationship
must at least imply such a duty.

WHEN IS INFORMATION NONPUBLIC?

     Information  remains  nonpublic until it has been made public.  Information
becomes public when it has been  effectively  communicated  to the  marketplace,
such as by a public filing with the SEC or other governmental AGENCY,  INCLUSION
IN THE DOW JONES  "TAPE" OR  PUBLICATION  IN THE WALL STREET  JOURNAL or another
publication of general circulation.  Moreover,  sufficient time must have passed
so that the information has been disseminated widely.

WHAT IS MATERIAL INFORMATION?

     Trading  on inside  information  is not a basis for  liability  unless  the
information is material.  "Material information" generally means information for
which  there  is a  substantial  likelihood  that a  reasonable  investor  would
consider it important in making his or her investment decisions,  or information
that is  reasonably  certain  to have a  substantial  effect  on the  price of a
company's  securities.  Information that should be considered material includes,
but  is not  limited  to:  dividend  changes,  earnings  estimates,  changes  in
previously  released  earnings  estimates,  significant  merger  or  acquisition
proposals  or  agreements,   major   litigation,   liquidation   problems,   and
extraordinary management developments.

     material  information  may  also  relate  to  the  MARKET  for a  company's
securities. Information about a significant order to purchase or sell securities
may, in some contexts, be deemed material. Similarly, prepublication information
regarding  reports  in the  financial  press  also may be deemed  material.  For
example,  the Supreme Court upheld the criminal  convictions of insider  trading
defendants who capitalized on  prepublication  INFORMATION ABOUT THE WALL STREET
JOURNAL'S "Heard on the Street" column.

WHEN IS INFORMATION MISAPPROPRIATED?

     The  misappropriation  theory prohibits  trading on the basis of non-public
information by a corporate  "outsider" in breach of a duty owed not to a trading
party,  but to the  source  of  confidential  information.  Misappropriation  of
information  occurs when a person  obtains the  non-public  information  through
deception  or in  breach  of a duty of trust and  loyalty  to the  source of the
information.

                                       15

PENALTIES FOR INSIDER TRADING

     Penalties for trading on or communicating  material  nonpublic  information
are severe,  both for  individuals  involved in such unlawful  conduct and their
employers or other controlling  persons.  A person can be subject to some or all
of the penalties  below even if he or she does not  personally  benefit from the
violation.

Penalties include:

     o    Civil injunctions

     o    Treble damages

     o    Disgorgement of profits

     o    Jail sentences for up to 10 years

     o    Fines up to  $1,000,000  (or  $2,500,000  for  corporations  and other
          entities)

     o    Civil  penalties  for the person who  committed the violation of up to
          three  times the  profit  gained or loss  avoided,  whether or not the
          person actually benefited, and

     o    Civil penalties for the employer or other controlling  person of up to
          the  greater  of  $1,000,000  or three  times the amount of the profit
          gained or loss avoided.

     In addition,  any  violation of the law may result in serious  sanctions by
Janus, including termination of employment.

WHO IS A CONTROLLING PERSON?

     Included as controlling  persons are Janus and its Directors,  Trustees and
officers.  If you are a Director,  Trustee or officer, you have a duty to act to
prevent insider trading.  Failure to fulfill such a duty may result in penalties
as described above.

                         PROCEDURES TO IMPLEMENT POLICY

     The  following  procedures  have  been  established  to aid the  Directors,
Trustees,  officers and employees of Janus in avoiding insider  trading,  and to
aid Janus in  preventing,  detecting  and  imposing  sanctions  against  insider
trading.

IDENTIFYING MATERIAL INSIDE INFORMATION

     Before  trading for yourself or others,  including the Janus Funds or other
Clients,  in the  securities  of a company  about  which you may have  potential
inside information, ask yourself the following questions:

     o    To whom has this information  been provided?  Has the information been
          effectively communicated to the marketplace?

                                       16
<PAGE>


     o    Has this  information  been  obtained  from  either the issuer or from
          another  source  in  breach  of a duty to  that  source  to  keep  the
          information confidential?

     o    Is the  information  material?  Is this  information  that an investor
          would consider important in making his or her investment decisions? Is
          this  information that would affect the market price of the securities
          if generally disclosed?

     Special   caution  should  be  taken  with  respect  to  potential   inside
information  regarding JCC. Although JCC's shares are not publicly traded, JCC's
parent,  KCSI, is a publicly traded company.  KCSI owns 82% of the stock of JCC.
As a result,  potential inside  information  regarding JCC may affect trading in
KCSI stock and should be reported  pursuant to the  procedures  set forth below.
The following is a non-exclusive  list of situations  that Investment  Personnel
should report immediately pursuant to the procedures below: (i) participation in
private placements;  (ii) the receipt of any information from an issuer pursuant
to a confidentiality agreement; (iii) participation on or receipt of information
from a  bankruptcy  committee  of an issuer;  and (iv)  receipt  of  information
regarding  earnings or sales  figures in advance of the public  release of those
numbers.

REPORTING INSIDE INFORMATION

     If, after  consideration  of the above, you believe that the information is
material and nonpublic,  or if you have questions as to whether the  information
is material and nonpublic, you should take the following steps:

     o    Do not  purchase  or sell the  securities  on  behalf of  yourself  or
          others, including Clients.

     o    Do not communicate the information  inside or outside of Janus,  other
          than to the Chief Compliance Officer or the Compliance Manager.

     o    Immediately  advise the Chief Compliance Officer or Compliance Manager
          of the  nature and source of such  information.  The Chief  Compliance
          Officer or  Compliance  Manager will review the  information  with the
          Ethics Committee.

     o    Depending upon the determination  made by the Ethics Committee,  or by
          the Chief Compliance Officer until the Committee can be convened,  you
          may be  instructed  to continue the  prohibition  against  trading and
          communication and the Compliance  Manager will place the security on a
          Restricted List or Watch List, as described below.  Alternatively,  if
          it is  determined  that  the  information  obtained  is  not  material
          nonpublic information, you may be allowed to trade and communicate the
          information.

WATCH AND RESTRICTED LISTS

     Whenever the Ethics  Committee or the Chief Compliance  Officer  determines
that a  Director,  Trustee,  officer or employee  of Janus is in  possession  of
material nonpublic  information with respect to a company (regardless of whether
it is  currently  owned by any Client)  such  company will either be placed on a
Watch List or on a Restricted List.

                                       17
<PAGE>


WATCH LIST

     If the security is placed on a Watch List,  the flow of the  information to
other  Janus  personnel  will be  restricted  in order to allow such  persons to
continue  their  ordinary  investment  activities.  This  procedure  is commonly
referred to as a "Chinese Wall."

RESTRICTED LIST

     If the Ethics  Committee or the Chief  Compliance  Officer  determines that
material  nonpublic  information  is in the  possession of a Director,  Trustee,
officer,  or employee of Janus and cannot be adequately isolated through the use
of a Chinese Wall,  the company will be placed on the Restricted  List.  While a
company is on the  Restricted  List,  no  Investment  Person  shall  initiate or
recommend any transaction in any Client  account,  and no Access Person shall be
precleared  to  transact  in any  account  in which  he or she has a  beneficial
interest,  with respect to the securities of such company.  The Ethics Committee
or the Chief  Compliance  Officer  will also have the  discretion  of  placing a
company on the Restricted List even though no "break in the Chinese Wall" has or
is expected to occur with respect to the material  nonpublic  information  about
the  company.  Such  action  may be taken by such  persons  for the  purpose  of
avoiding any appearance of the misuse of material nonpublic information.

     The Ethics  Committee or the Chief  Compliance  Officer will be responsible
for  determining  whether to remove a particular  company from the Watch List or
Restricted  List.  The only  persons  who will have  access to the Watch List or
Restricted  List  are  members  of the  Ethics  Committee,  Designated  Legal or
Compliance Representatives and such persons who are affected by the information.
The Watch List and Restricted List are highly confidential and should,  under no
circumstances,  be  discussed  with or  disseminated  to anyone  other  than the
persons noted above.

PROTECTING INFORMATION

     Directors, Trustees, officers and employees of Janus shall not disclose any
nonpublic  information  (whether or not it is material) relating to Janus or its
securities  transactions to any person outside Janus (unless such disclosure has
been authorized by the Chief Compliance Officer). Material nonpublic information
may not be communicated to anyone,  including any Director,  Trustee, officer or
employee of Janus, except as provided in this Policy. Access to such information
must be restricted.  For example,  access to files containing material nonpublic
information and computer files containing such information should be restricted,
and conversations containing such information,  if appropriate at all, should be
conducted in private.

     To  insure  the  integrity  of the  Chinese  Wall and to  avoid  unintended
disclosures,  it is important that all employees  take the following  steps with
respect to confidential or nonpublic information:

     o    Do not  discuss  confidential  information  in public  places  such as
          elevators, hallways or social gatherings.

     o    To the extent  practical,  limit access to the areas of the firm where
          confidential  information  could be observed or overheard to employees
          with a business need for being in the area.

     o    Avoid use of  speakerphones  in areas where  unauthorized  persons may
          overhear conversations.

                                       18
<PAGE>

     o    Avoid  use  of  wireless  and  cellular  phones,  or  other  means  of
          communication, which may be intercepted.

     o    Where appropriate,  maintain the  confidentiality of Client identities
          by using code names or numbers for confidential projects.

     o    Exercise  care to  avoid  placing  documents  containing  confidential
          information  in areas where they may be read by  unauthorized  persons
          and to store such  documents in secure  locations when they are not in
          use.

     o    Destroy  copies  of  confidential  documents  no longer  needed  for a
          project  unless  required to be saved  pursuant to  applicable  record
          keeping policies or requirements.

RESPONSIBILITY TO MONITOR TRANSACTIONS

     Compliance  will monitor  transactions  of Clients and  employees for which
reports are received to detect the existence of any unusual  trading  activities
with respect to companies on the Watch and  Restricted  Lists.  Compliance  will
immediately  report any unusual  trading  activity  directly  to the  Compliance
Manager,  and in his or her absence,  the Chief Compliance Officer,  who will be
responsible for determining what, if any, action should be taken.

RECORD RETENTION

     Compliance  shall maintain copies of the Watch List and Restricted List for
a minimum of six years.

TENDER OFFERS

     Tender offers represent a particular  concern in the law of insider trading
for two reasons.  First,  tender offer  activity  often  produces  extraordinary
fluctuations  in the price of the target  company's  securities.  Trading during
this time period is more likely to attract regulatory  attention (and produces a
disproportionate  percentage  of insider  trading  cases).  Second,  the SEC has
adopted a rule which expressly forbids trading and "tipping" while in possession
of material  nonpublic  information  regarding a tender offer  received from the
tender offeror,  the target company or anyone acting on behalf of either.  Janus
employees and others subject to this Policy should exercise  particular  caution
any time they become aware of nonpublic information relating to a tender offer.

- --------------------------------------------------------------------------------
                                   GIFT POLICY
- --------------------------------------------------------------------------------

     GIFTS  MAY BE  GIVEN  (OR  ACCEPTED)  only if they are in  accordance  with
normally  accepted  business   practices  and  do  not  raise  any  question  of
impropriety.  A question of  impropriety  may be raised if a gift  influences or
gives the  appearance of  influencing  the  recipient.  The  following  outlines
Janus's policy on giving and receiving gifts to help us maintain those standards
and is applicable  to all Inside  Directors  and Inside  Trustees,  officers and
employees of Janus.

                                   GIFT GIVING

     Neither you nor members of your immediate family may give any gift,  series
of gifts, or other thing of value,  including cash, loans, personal services, or
special discounts  ("Gifts") in excess of $100 per year to any Client or any one
person or entity that does or seeks to do business with or on behalf of Janus or
any Client (collectively referred to herein as "Business Relationships").

                                 GIFT RECEIVING

     Neither  you nor members of your  immediate  family may receive any Gift of
material value from any single Business Relationship.  A Gift will be considered
material in value if it influences or gives the  appearance of  influencing  the
recipient.

     In the event the aggregate  fair market value of all Gifts  received by you
from any  single  Business  Relationship  is  estimated  to  exceed  $250 in any
12-month period, you must immediately notify your manager. Managers that receive
such notification  must report this information to the Compliance  Manager if it
appears that such Gifts may have improperly influenced the receiver. If the Gift
is made in connection  with the sale or  distribution  of registered  investment
company or variable contract securities,  the aggregate fair market value of all
such Gifts  received  by you from any  single  Business  Relationship  may never
exceed $100 in any 12-month period.

     Occasionally,  Janus  employees  are  invited to attend or  participate  in
conferences,  tour a company's  facilities,  or meet with  representatives  of a
company.  Such  invitations  may involve  traveling  and may  require  overnight
lodging.  Generally, Janus must pay for all travel and lodging expenses provided
in connection with such  activities.  However,  if  appropriate,  and with prior
approval from your manager, you may accept travel related amenities if the costs
are considered insubstantial and are not readily ascertainable.

     The solicitation of a gift is prohibited (i.e., you may not request a gift,
such as tickets to a sporting event, be given to you).

                          CUSTOMARY BUSINESS AMENITIES

         Customary  business  amenities are not considered gifts so long as such
amenities are business related (e.g., if you are accepting tickets to a sporting
event, the offerer must go with you), reasonable in cost, appropriate as to time
and place,  and  neither so frequent  nor so costly as to raise any  question of
impropriety.  Customary business  amenities which you and, if appropriate,  your
guests,  may accept (or give) include an occasional meal, a ticket to a sporting
event or the theater,  greens  fees,  an  invitation  to a reception or cocktail
party, or comparable entertainment.

                                       20

- --------------------------------------------------------------------------------
                           OUTSIDE EMPLOYMENT POLICY
- --------------------------------------------------------------------------------

     No Inside  Director,  Inside  Trustee,  officer or  employee of Janus shall
accept  employment or compensation  as a result of any business  activity (other
than a passive  investment),  outside the scope of his  relationship  with Janus
unless such person has provided  prompt  written  notice of such  employment  or
compensation to the Chief  Compliance  Officer (or, for Registered  Persons,  to
JDI's Operations Manager), and, in the case of securities-related  employment or
compensation,  has received the prior written approval of the Ethics  Committee.
Registered  Persons are  reminded to update and submit  their  Outside  Business
Activity  Disclosure forms as appropriate  pursuant to JDI's Written Supervisory
Procedures and applicable NASD rules.

                               PENALTY GUIDELINES
- --------------------------------------------------------------------------------

                                    OVERVIEW

     Covered  Persons  who  violate any of the  requirements,  restrictions,  or
prohibitions  of the Rules may be  subject  to  sanctions  imposed by the Ethics
Committee.  The following guidelines shall be used by the Compliance Manager for
recommending  remedial  actions for Covered Persons who violate  prohibitions or
disregard  requirements of the Rules.  Deviations from the Fifteen-Day  Rule are
not considered to be violations under the Rules and, therefore,  are not subject
to the penalty guidelines.

     Upon learning of a potential deviation from, or violation of the Rules, the
Compliance  Manager will provide a written  recommendation of remedial action to
the Ethics  Committee.  The Ethics Committee has full discretion to approve such
recommendation  or impose  other  sanctions  it deems  appropriate.  The  Ethics
Committee  will  take  into  consideration,  among  other  things,  whether  the
violation was a technical violation of the Rules or inadvertent oversight (i.e.,
ill-gotten  profits  versus general  oversight).  The guidelines are designed to
promote   consistency   and  uniformity  in  the  imposition  of  sanctions  and
disciplinary matters.

                               PENALTY GUIDELINES

     Outlined  below are the guidelines for the sanctions that may be imposed on
Covered Persons who fail to comply with the Rules:

     o    1st violation-  Compliance  will send a memorandum of reprimand to the
          person,  copying his or her supervisor.  The memorandum will generally
          reinforce the person's  responsibilities  under the Rules, educate the
          person on the severity of personal  trading  violations and inform the
          person of the possible penalties for future violations of the Rules;

     o    2nd violation-  Janus's Chief Investment  Officer,  James Craig,  will
          meet with the  person to  discuss  the  violations  in detail and will
          reinforce the importance of complying with the Rules;

     o    3rd violation- Janus's Chairman of the Board, Thomas Bailey, will meet
          with the person to discuss the violations in detail and will reinforce
          the importance of complying with the Rules;

     o    4th violation-  The Executive  Committee will impose such sanctions as
          it deems  appropriate,  including  without  limitation,  a  letter  of
          censure,  fines,  withholding  of bonus  payments,  or  suspension  or
          termination of employment or personal trading privileges.

     In  addition  to the above  disciplinary  sanctions,  such  persons  may be
required to disgorge any profits realized in connection with such violation. All
disgorgement  proceeds  collected  will be donated to a charitable  organization
selected by the Ethics  Committee.  The Ethics Committee may determine to impose
any  of  the  sanctions  set  forth  in  item 4  above,  including  termination,
immediately  and  without  notice  if it  determines  that the  severity  of any
violation or  violations  warrants such action.  All  sanctions  imposed will be
documented in such person's  personal trading file maintained by Janus, and will
be reported to the Executive Committee.

                      SUPERVISORY AND COMPLIANCE PROCEDURES
- --------------------------------------------------------------------------------

     The Chief  Compliance  Officer and Compliance  Manager are  responsible for
implementing   supervisory  and  compliance   review   procedures.   Supervisory
procedures can be divided into two classifications: prevention of violations and
detection of violations.  Compliance  review procedures  include  preparation of
special and annual reports,  record maintenance and review, and  confidentiality
preservation.

                             SUPERVISORY PROCEDURES

PREVENTION OF VIOLATIONS

     To prevent  violations of the Rules,  the  Compliance  Manager  should,  in
addition to enforcing the procedures outlined in the Rules:

     1.   Review  and  update the Rules as  necessary,  at least once  annually,
          including  but not  limited  to a  review  of the  Code  by the  Chief
          Compliance Officer, the Ethics Committee and/or counsel;

     2.   Answer  questions  regarding the Rules, or refer the same to the Chief
          Compliance Officer;

     3.   Request from all persons upon  commencement of services,  and annually
          thereafter, any applicable forms and reports as required by the Rules;

     4.   Identify all Access Persons and notify them of their  responsibilities
          and reporting requirements;

     5.   Write   letters  to  the   securities   firms   requesting   duplicate
          confirmations and account statements where necessary; and

     6.   With such  assistance  from the Human  Resources  Department as may be
          appropriate, maintain a continuing education program consisting of the
          following:

          1)   Orienting Covered Persons who are new to Janus to the Rules, and

          2)   Further educating Covered Persons by distributing  memos or other
               materials that may be issued by outside organizations such as the
               Investment  Company  Institute  discussing  the issue of  insider
               trading and other issues raised by the Rules.

DETECTION OF VIOLATIONS

     To detect  violations of these Rules,  the Compliance  Manager  should,  in
addition to enforcing the procedures outlined in the Rules:

          o    Implement  procedures to review holding and transaction  reports,
               confirmations,   forms  and  statements  relative  to  applicable
               restrictions, as provided under the Code; and

                                       23
<PAGE>



          o    Implement  procedures  to review the  Restricted  and Watch Lists
               relative to applicable  personal and Client trading activity,  as
               provided under the Policy.

     Spot checks of certain information are permitted as noted under the Code.

                              COMPLIANCE PROCEDURES

REPORTS OF POTENTIAL DEVIATIONS OR VIOLATIONS

     Upon learning of a potential deviation from, or violation of the Rules, the
Compliance Manager shall report such violation to the Chief Compliance  Officer,
together with all documents relating to the matter. The Chief Compliance Officer
shall either present the  information at the next regular  meeting of the Ethics
Committee,  or conduct a special meeting.  The Ethics Committee shall thereafter
take such action as it deems appropriate (see Penalty Guidelines).

ANNUAL REPORTS

     The  Compliance  Manager  shall  prepare  a written  report  to the  Ethics
Committee and the Trustees at least annually. The written report to the Trustees
shall include any  certification  required by Rule 17j-1.  This report shall set
forth the following information, and shall be confidential:

          o    Copies of the  Rules,  as  revised,  including  a summary  of any
               changes made since the last report;

          o    Identification  of any material  issues  arising  under the Rules
               including  material  violations  requiring  significant  remedial
               action since the last report;

          o    Identification  of any  material  conflicts  that arose since the
               last report; and

          o    Recommendations,   if  any,   regarding   changes   in   existing
               restrictions or procedures  based upon Janus's  experience  under
               these Rules,  evolving  industry  practices,  or  developments in
               applicable laws or regulations.

     The  Trustees  must  initially  approve  these Rules  within the time frame
required  by Rule 17-1.  Any  material  changes to these  Rules must be approved
within six months.

          o    A copy of each report made to the Trustees pursuant to this Code.

INSPECTION

     The records  and reports  maintained  by  Compliance  pursuant to the Rules
shall at all times be available for  inspection,  without  prior notice,  by any
member of the Ethics Committee.

CONFIDENTIALITY

     All  procedures,  reports and  records  monitored,  prepared or  maintained
pursuant to these Rules shall be  considered  confidential  and  proprietary  to
Janus and shall be  maintained  and protected  accordingly.  Except as otherwise
required by law or this Policy,  such  matters  shall not be disclosed to anyone
other than to members of the Ethics Committee, as requested.

FILING OF REPORTS

     To the extent that any report,  form  acknowledgment  or other  document is
required to be in writing and signed,  such  documents  may be  submitted  in by
e-mail or other  electronic  form approved by Compliance.  Any report filed with
the Chief Compliance  Officer or Compliance Manager of JCC shall be deemed filed
with the Janus Funds.

                              THE ETHICS COMMITTEE

     The purpose of this Section is to describe the Ethics Committee. The Ethics
Committee is created to provide an effective mechanism for monitoring compliance
with the standards and procedures contained in the Rules and to take appropriate
action at such times as violations or potential violations are discovered.

MEMBERSHIP OF THE COMMITTEE

     The  Committee  consists of Thomas A.  Early,  Vice  President  and General
Counsel;  Steven R.  Goodbarn,  Vice  President of Finance,  Treasurer and Chief
Financial Officer; David Kowalski,  Vice President and Chief Compliance Officer;
and Ernie C. Overholt,  Compliance  Manager.  The Compliance  Manager  currently
serves as the Chairman of the Committee. The composition of the Committee may be
changed from time to time.

COMMITTEE MEETINGS

     The  Committee  shall  generally  meet  every  four  months  or as often as
necessary  to  review  operation  of the  compliance  program  and  to  consider
technical deviations from operational procedures, inadvertent oversights, or any
other  potential  violation  of  the  Rules.  Deviations  alternatively  may  be
addressed by

                                       25
<PAGE>

including  them  in  the  employee's  personnel  records  maintained  by  Janus.
Committee  meetings  are  primarily  intended for  consideration  of the general
operation of the compliance  program and substantive or serious  departures from
standards and procedures in the Rules.

     Such other persons may attend a Committee meeting, at the discretion of the
Committee, as the Committee shall deem appropriate. Any individual whose conduct
has given rise to the meeting  also may be called  upon,  but shall not have the
right, to appear before the Committee.

     It is not required  that minutes of Committee  meetings be  maintained;  in
lieu of minutes the  Committee may issue a report  describing  any action taken.
The  report  shall  be  included  in the  confidential  file  maintained  by the
Compliance  Manager with respect to the particular  employee or employees  whose
conduct has been the subject of the meeting.

SPECIAL DISCRETION

     The Committee  shall have the  authority by unanimous  action to exempt any
person or class of persons or transaction or class of transactions from all or a
portion of the Rules, provided that:

          o    The  Committee  determines,   on  advice  of  counsel,  that  the
               particular  application  of all or a portion  of the Rules is not
               legally required;

          o    The Committee  determines that the likelihood of any abuse of the
               Rules by such exempted  person(s) or as a result of such exempted
               transaction is remote;

          o    The terms or conditions  upon which any such exemption is granted
               is evidenced in writing; and

          o    The  exempted  person(s)  agrees to  execute  and  deliver to the
               Compliance  Manager, at least annually,  a signed  Acknowledgment
               Form, which Acknowledgment shall, by operation of this provision,
               include such  exemptions and the terms and conditions  upon which
               it was granted.

     The Committee  shall also have the authority by unanimous  action to impose
such additional  requirements  or  restrictions  as it, in its sole  discretion,
determines appropriate or necessary, as outlined in the Penalty Guidelines.

     Any  exemption,  and any  additional  requirement  or  restriction,  may be
withdrawn by the Committee at any time (such  withdrawal  action is not required
to be unanimous).

                   GENERAL INFORMATION ABOUT THE ETHICS RULES
- --------------------------------------------------------------------------------

DESIGNEES

     The  Compliance  Manager  and the  Chief  Compliance  Officer  may  appoint
designees to carry out their functions pursuant to these Rules.

ENFORCEMENT

     In addition  to the  penalties  described  in the  Penalty  Guidelines  and
elsewhere in the Rules,  upon  discovering  a violation of the Rules,  the Janus
entity  with which you are  associated  may impose  such  sanctions  as it deems
appropriate,  including without limitation, a letter of censure or suspension or
termination of employment or personal  trading  privileges of the violator.  All
material  violations of the Rules and any sanctions imposed with respect thereto
shall be reported  periodically  to the Directors and Trustees and the directors
of any other Janus entity which has been directly affected by the violation.

INTERNAL USE

     The  Rules  are  intended  solely  for  internal  use by  Janus  and do not
constitute an admission,  by or on behalf of such companies,  their  controlling
persons  or  persons  they  control,  as to  any  fact,  circumstance  or  legal
conclusion.  The Rules are not  intended  to  evidence,  describe  or define any
relationship of control between or among any persons. Further, the Rules are not
intended to form the basis for  describing  or defining  any conduct by a person
that  should  result in such person  being  liable to any other  person,  except
insofar as the conduct of such person in violation  of the Rules may  constitute
sufficient  cause for Janus to  terminate  or  otherwise  adversely  affect such
person's relationship with Janus.
