               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 Institutional Shares (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.

               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

 2 Janus Aspen Series prospectus
<PAGE>

               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.

               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

                                                Janus Aspen Series prospectus  3
<PAGE>

               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

<PAGE>

               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 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

                                                Janus Aspen Series prospectus  5
<PAGE>

               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.

               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.

 12 Janus Aspen Series prospectus
<PAGE>

               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

               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.

                                               Janus Aspen Series prospectus  15
<PAGE>

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.

   * Expenses (except for Global Technology and Global Life Sciences
     Portfolios) are based upon expenses for the fiscal year ended December

     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:

               Although it is anticipated that each Portfolio and its
               corresponding retail fund will hold similar securities,
               differences in asset size, cash flow needs and other factors may
               result in differences in investment performance. The expenses of
               each Portfolio and its corresponding retail fund are expected to
               differ. The variable contract owner will also bear various
               insurance related costs at the insurance company level. You
               should review the accompanying separate account prospectus for a
               summary of fees and expenses.

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.

               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

<PAGE>

               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

                                               Janus Aspen Series prospectus  23
<PAGE>

               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.

                                               Janus Aspen Series prospectus  25
<PAGE>

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

 26 Janus Aspen Series prospectus
<PAGE>

               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 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

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 35-40 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

                                               Janus Aspen Series prospectus  29
<PAGE>

               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

 30 Janus Aspen Series prospectus
<PAGE>

               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

                                               Janus Aspen Series prospectus  31
<PAGE>

               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, govern-

 32 Janus Aspen Series prospectus
<PAGE>

               ment 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.

                                               Janus Aspen Series prospectus  33
<PAGE>

               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 Life Sciences Portfolio's and 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

                                               Janus Aspen Series prospectus  35
<PAGE>

               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 82-84 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:

                                               Janus Aspen Series prospectus  37
<PAGE>

               - 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 82-84
               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

                                               Janus Aspen Series prospectus  39
<PAGE>

               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

                                               Janus Aspen Series prospectus  41
<PAGE>

               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

               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

<PAGE>

                 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.

                                               Janus Aspen Series prospectus  43
<PAGE>

               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.

               companies for such services.

OTHER INFORMATION
- --------------------------------------------------------------------------------

               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

                                               Janus Aspen Series prospectus  55
<PAGE>

               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

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,

                                               Janus Aspen Series prospectus  57
<PAGE>

               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.

               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.

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.

                                               Janus Aspen Series prospectus  59
<PAGE>

               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.

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

                                               Janus Aspen Series prospectus  75
<PAGE>

               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
               Portfolios must pay if these investments are profitable, the
               Portfolios may

 76 Janus Aspen Series prospectus
<PAGE>

               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.

                                               Janus Aspen Series prospectus  77
<PAGE>

               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

 78 Janus Aspen Series prospectus
<PAGE>

               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.

                                               Janus Aspen Series prospectus  79
<PAGE>

               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.

                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.

                                          to the issuer's capacity to meet
                                          required interest and principal
                                          payments. BB - lowest degree of

                                          to adverse conditions.

               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.

RISK RETURN SUMMARY
- --------------------------------------------------------------------------------

STRATEGIC VALUE PORTFOLIO

               Strategic Value Portfolio is designed for long-term investors who
               seek growth of capital and who can tolerate the greater risks
               associated with common stock investments.

1. WHAT IS THE INVESTMENT OBJECTIVE OF STRATEGIC VALUE PORTFOLIO?

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

               STRATEGIC VALUE PORTFOLIO seeks long-term growth of capital.

               The Portfolio's Trustees may change the objective without a
               shareholder vote and the Portfolio will notify you of any
               changes that are material. If there is a material change to
               the Portfolio's objective or policies, you should consider
               whether the Portfolio 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 STRATEGIC VALUE PORTFOLIO?

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

               STRATEGIC VALUE PORTFOLIO invests primarily in common stocks with
               the potential for long-term growth of capital using a "value"
               approach. The "value" approach the portfolio manager uses
               emphasizes investments in companies he believes are undervalued
               relative to their intrinsic worth.

               The portfolio manager measures value as a function of
               price/earnings (P/E) ratios and price/free cash flow. A P/E ratio
               is the relationship between the price of a stock and its earnings
               per share. This figure is determined by dividing a stock's market
               price by the company's earnings per share amount. Price/free cash
               flow is the relationship between the price of a stock and its
               available cash from operations minus capital expenditures.

 2 Janus Aspen Series prospectus
<PAGE>

               The portfolio manager will typically seek attractively valued
               companies that are improving their free cash flow and improving
               their returns on invested capital. These companies may also
               include special situations companies that are experiencing
               management changes and/or are temporarily out of favor.

               The Portfolio may invest without limit in foreign equity and debt
               securities and less than 35% of its net assets in
               high-yield/high-risk bonds.

3. WHAT ARE THE MAIN RISKS OF INVESTING IN STRATEGIC VALUE PORTFOLIO?

               The biggest risk of investing in this Portfolio is that its
               returns may vary, and you could lose money. If you are
               considering investing in Strategic Value Portfolio, remember that
               it is 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 the Portfolio's holdings may decrease if the value
               of an individual company in the portfolio decreases or if the
               portfolio manager's belief about a company's intrinsic worth is
               incorrect. The value of the Portfolio's holdings could also
               decrease if the stock market goes down. If the value of the
               Portfolio's holdings decreases, its net asset value (NAV) will
               also decrease,which means if you sell your shares in the
               Portfolio you would get back less money.

               The Portfolio is nondiversified. In other words, it 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 the Portfolio's
               NAV and total return.

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

               Since the Portfolio did not commence operations until May 1,
               2000, there is no performance available as of the date of this
               prospectus.

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 Portfolio.
               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 the 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
               below shows, these costs are borne indirectly by all
               shareholders.

               This table and example are designed to assist participants in
               qualified plans that invest in the Shares of the Portfolio 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 REFLECT DEDUCTIONS AT THE SEPARATE
               ACCOUNT LEVEL OR CONTRACT LEVEL FOR ANY CHARGES THAT MAY BE
               INCURRED UNDER A CONTRACT.

INVESTMENT OBJECTIVE, PRINCIPAL INVESTMENT
STRATEGIES AND RISKS
- --------------------------------------------------------------------------------


               Strategic Value Portfolio has a similar investment objective and
               similar principal investment strategies to Janus Strategic Value
               Fund. Although it is anticipated that the Portfolio and Janus
               Strategic Value Fund will hold similar securities, differences in
               asset size, cash flow needs and other factors may result in
               differences in investment performance. The expenses of the
               Portfolio and Janus Strategic Value Fund are expected to differ.
               The variable contract owner will also bear various insurance
               related costs at the insurance company level. You should review
               the accompanying separate account prospectus for a summary of
               fees and expenses.

INVESTMENT OBJECTIVE AND PRINCIPAL INVESTMENT STRATEGIES

               This section takes a closer look at the investment objective of
               Strategic Value Portfolio, its principal investment strategies
               and certain risks of investing in Strategic Value Portfolio.
               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 11-14 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.

               Strategic Value Portfolio seeks long-term growth of capital. It
               pursues its objective by investing primarily in common stocks
               with the potential for long-term growth of capital using a
               "value" approach. The "value" approach the portfolio manager uses
               emphasizes investments in companies he believes are undervalued
               relative to their intrinsic worth.

               The portfolio manager measures value as a function of
               price/earnings (P/E) ratios and price/free cash flow. A P/E ratio
               is the relationship between the price of a stock and its earnings
               per share. This figure is determined by dividing a stock's market
               price by the company's earnings per share amount. Price/free cash
               flow is the relationship between the price of a stock and its
               available cash from operations minus capital expenditures.

 6 Janus Aspen Series prospectus
<PAGE>

               The portfolio manager will typically seek attractively valued
               companies that are improving their free cash flow and improving
               their returns on invested capital. These companies may also
               include special situations companies that are experiencing
               management changes and/or are temporarily out of favor.

The following questions and answers are designed to help you better understand
Strategic Value Portfolio's principal investment strategies.

1. HOW ARE COMMON STOCKS SELECTED?

               The Portfolio may invest substantially all of its assets in
               common stocks if the portfolio manager believes that common
               stocks will appreciate in value. The portfolio manager generally
               takes a "bottom up" approach to selecting companies. In other
               words, he seeks to identify individual companies with earnings
               growth potential that may not be recognized by the market at
               large. He makes 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.
               Realization of income is not a significant consideration when
               choosing investments for the Portfolio. Income realized on the
               Portfolio's investments will be incidental to its objective.

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

               Generally, yes. The portfolio manager seeks companies that meet
               his 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 Portfolio may invest and the Portfolio may at times have
               significant foreign exposure.

3. HOW DOES THE PORTFOLIO MANAGER DETERMINE THAT A COMPANY MAY BE UNDERVALUED?

               A company may be undervalued when, in the opinion of the
               portfolio manager, the company is selling for a price that is
               below its intrinsic worth. A company may be undervalued due to
               market or economic conditions, temporary earnings declines,
               unfavorable developments affecting the company or other factors.
               Such factors may provide buying opportunities at attractive
               prices compared to historical or market price-earnings ratios,
               price/free cash flow, book value, or return on equity. The
               portfolio manager believes that buying these securities at a
               price that is below its intrinsic worth may generate greater
               returns for the Portfolio than those obtained by paying premium
               prices for companies currently in favor in the market.

4. 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. Although Equity Income
               Portfolio does not emphasize companies of any particular size, a
               Portfolio with a larger asset base are more likely to invest in
               larger, more established issuers.

GENERAL PORTFOLIO POLICIES

               In investing its portfolio assets, the Portfolio will follow the
               general policies listed below. 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 the
               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 the portfolio manager believes that market conditions are
               unfavorable for profitable investing, or when he is otherwise

 8 Janus Aspen Series prospectus
<PAGE>

               unable to locate attractive investment opportunities, the
               Portfolio's cash or similar investments may increase. In other
               words, the Portfolio does not always stay fully invested in
               stocks and bonds. Cash or similar investments generally are a
               residual - they represent the assets that remain after the
               portfolio manager has committed available assets to desirable
               investment opportunities. However, the portfolio manager may also
               temporarily increase the Portfolio's cash position to protect its
               assets or maintain liquidity.

               When the 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
               Strategic Value Portfolio invests primarily in domestic and
               foreign equity securities, which may include preferred stocks,
               common stocks, warrants and securities convertible into common or
               preferred stocks. The Portfolio 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 the 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

               ILLIQUID INVESTMENTS
               The 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

                                                Janus Aspen Series prospectus  9
<PAGE>

               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 Portfolio's
               Trustees, certain restricted securities may be deemed liquid, and
               will not be counted toward this 15% limit.

               FOREIGN SECURITIES
               The Portfolio may invest without limit in foreign equity and debt
               securities. The Portfolio 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
               The Portfolio may invest in special situations. A special
               situation arises when, in the opinion of the 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. The 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 Portfolio generally intends to purchase securities for
               long-term investment although, to a limited extent, the 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

 10 Janus Aspen Series prospectus
<PAGE>

               investment decision. The 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 the Portfolio's holdings
               whenever the portfolio manager believes such changes are
               desirable. Portfolio turnover rates are generally not a factor in
               making buy and sell decisions.

               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
               the Portfolio's performance.

RISKS FOR STRATEGIC VALUE PORTFOLIO

               Because the Portfolio may invest substantially all of its assets
               in common stocks, the main risk is the risk that the value of the
               stocks it holds might decrease in response to the activities of
               an individual company or in response to general market and/or
               economic conditions. If this occurs, the Portfolio's share price
               may also decrease. The Portfolio's performance may also be
               affected by risks specific to certain types of investments, such
               as foreign securities, derivative investments, non-investment
               grade bonds, 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 Strategic Value Portfolio.

1. THE PORTFOLIO 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

                                               Janus Aspen Series prospectus  11
<PAGE>

               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 STRATEGIC VALUE PORTFOLIO AFFECT ITS
   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 the Portfolio.

3. WHAT ARE THE RISKS ASSOCIATED WITH VALUE INVESTING?

               If the portfolio manager's perception of a company's worth is not
               realized in the time frame he expects, the overall performance of
               the Portfolio may suffer. In addition, if the market value of a
               company declines the Portfolio's performance could suffer. In
               general, the portfolio manager believes these risks are mitigated
               by investing in companies that are undervalued in the market in
               relation to earnings, dividends and/or assets.

4. HOW COULD THE PORTFOLIO'S INVESTMENTS IN FOREIGN SECURITIES AFFECT ITS
   PERFORMANCE?

               The Portfolio 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 Portfolio's
               performance may depend on issues other than the performance of a
               particular company. These issues include:

               - CURRENCY RISK. As long as the Portfolio holds a foreign
                 security, its value will be affected by the value of the local
                 currency relative to the U.S. dollar. When the 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 the 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

                                               Janus Aspen Series prospectus  13
<PAGE>

                 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.

5. 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.

               Please refer to the SAI for a description of bond rating
               categories.

6. HOW DOES THE PORTFOLIO TRY TO REDUCE RISK?

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

MANAGEMENT OF THE PORTFOLIO
- --------------------------------------------------------------------------------

INVESTMENT ADVISER

               Janus Capital, 100 Fillmore Street, Denver, Colorado 80206-4928,
               is the investment adviser to the Portfolio and is responsible for
               the day-to-day management of the investment portfolio and other
               business affairs of the Portfolio.

               Janus Capital began serving as investment adviser to Janus Fund
               in 1970 and currently serves as investment adviser to all of the
               Janus retail funds, acts as sub-adviser for a number of
               private-label mutual funds and provides separate account advisory
               services for institutional accounts.

               Janus Capital furnishes continuous advice and recommendations
               concerning the Portfolio's investments. Janus Capital also
               furnishes certain administrative, compliance and accounting
               services for the Portfolio, and may be reimbursed by the
               Portfolio for its costs in providing those services. In addition,
               Janus Capital employees serve as officers of the Trust and Janus
               Capital provides office space for the Portfolio and pays the
               salaries, fees and expenses of all Portfolio officers and those
               Trustees who are affiliated with Janus Capital.

               Participating insurance companies that purchase the Portfolio's
               Shares may perform certain administrative services relating to
               the Portfolio and Janus Capital or the Portfolio may pay those
               companies for such services.

MANAGEMENT EXPENSES AND EXPENSE LIMITS

               The Portfolio pays Janus Capital a management fee which is
               calculated daily and paid monthly. The advisory agreement with
               the Portfolio spells out the management fee and other expenses
               that the Portfolio must pay. The Portfolio is subject to the
               following management fee schedule (expressed as an annual rate).
               In addition, the Shares of the Portfolio incur expenses not
               assumed by Janus Capital, including transfer agent and custodian
               fees and expenses, legal and auditing fees, printing and mailing
               costs of sending reports and other information to existing
               shareholders, and independent Trustees' fees and expenses.

OTHER INFORMATION
- --------------------------------------------------------------------------------

               CLASSES OF SHARES

               The Portfolio offers two 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
               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
               Service Shares, please call 1-800-525-0020.

               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. Although the Portfolio does not
               currently anticipate any disadvantages to policy owners because
               the 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 the Portfolio or substitute Shares of another
               Portfolio. If this occurs, the Portfolio may be forced to sell
               its securities at disadvantageous prices. In addition, the
               Trustees may refuse to sell Shares of the Portfolio to any
               separate account or qualified plan or may suspend or terminate
               the offering of the Portfolio's Shares if such action is required
               by law or regulatory authority or is in the best interests

<PAGE>

               of the Portfolio's shareholders. It is possible that a qualified
               plan investing in the Portfolio 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 Portfolio. Janus Capital intends to monitor such qualified
               plans and the Portfolio may discontinue sales to a qualified plan
               and require plan participants with existing investments in the
               Portfolio 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 THE PORTFOLIO

               The Portfolio is distributed by Janus Distributors, Inc., a
               member of the National Association of Securities Dealers, Inc.

DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------

DISTRIBUTIONS

               To avoid taxation of the Portfolio, the Internal Revenue Code
               requires the Portfolio to distribute net income and any net gains
               realized on its investments annually. The 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.

               Each class of the 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 the Portfolio will automatically be
               reinvested into additional Shares of the Portfolio.

               HOW DISTRIBUTIONS AFFECT NAV

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

TAXES

               TAXES ON DISTRIBUTIONS

               Because Shares of the Portfolio 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 the Portfolio will be exempt
               from current taxation if left to accumulate within the variable
               insurance contract or

 20 Janus Aspen Series prospectus
<PAGE>

               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 PORTFOLIO

               Dividends, interest and some gains received by the Portfolio on
               foreign securities may be subject to tax withholding or other
               foreign taxes. The Portfolio 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 Portfolio which will
               reduce its investment income.

               The Portfolio does not expect to pay any federal income or excise
               taxes because it intends to meet certain requirements of the
               Internal Revenue Code. In addition, because the Shares of the
               Portfolio are sold in connection with variable insurance
               contracts, the 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 PORTFOLIO
               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. 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 THE PORTFOLIO AS AN INVESTMENT
               OPTION 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 the 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
               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 the Portfolio holds securities that are primarily
               listed on foreign exchanges that trade on weekends or other days
               when the Portfolio does not price its shares, the NAV of the
               Portfolio's shares may change on days when shareholders will not
               be able to purchase or redeem the Portfolio's shares.

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

 22 Janus Aspen Series prospectus
<PAGE>

               documents for information on how to invest in the Shares of the
               Portfolio. Participating insurance companies and certain other
               designated organizations are authorized to receive purchase
               orders on the Portfolio's behalf.

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

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 the Portfolio's investments. The
               Portfolio does not permit frequent trading or market timing. When
               market timing occurs, the 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 the
               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 the Portfolio will have to invest. When in
               Janus Capital's opinion such activity would have a disruptive
               effect on portfolio management, the Portfolio reserves the right
               to refuse purchase orders and exchanges into the Portfolio by any
               person, group or commonly controlled account. The Portfolio may
               notify a market timer of rejection of a purchase or exchange
               order after the day the order is placed. If the 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 Portfolio that they
               have authorized for investment. Each report will show the
               investments owned by the Portfolio and the market values thereof,
               as well as other information about the Portfolio and its
               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 Portfolio
               may invest. The Portfolio may invest in these instruments to the
               extent permitted by its investment objective and policies. The
               Portfolio is 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
               Portfolio 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

 26 Janus Aspen Series prospectus
<PAGE>

               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, the 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
               Portfolio must pay if these investments are profitable, the
               Portfolio may

                                               Janus Aspen Series prospectus  27
<PAGE>

               make various elections permitted by the tax laws. These elections
               could require that the Portfolio 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 the
               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, the 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
               the 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 the Portfolio
               from a dealer that give the Portfolio the option to sell a
               security to the dealer at a specified price.

 28 Janus Aspen Series prospectus
<PAGE>

               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

                                               Janus Aspen Series prospectus  29
<PAGE>

               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
               Portfolio does 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
               Portfolio 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. It may also enter into forward contracts to
               purchase or sell securities or other financial indices.

 30 Janus Aspen Series prospectus
<PAGE>

               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 Portfolio 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 Portfolio 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. The 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.

                                               Janus Aspen Series prospectus  31
<PAGE>

               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 Portfolio may purchase
               and write put and call options on securities, securities indices
               and foreign currencies.

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.

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.

                                                                               3
<PAGE>

          (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 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

 4
<PAGE>

          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

                                                                               5
<PAGE>

          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 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

 6
<PAGE>

          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.

                                                                               7
<PAGE>

          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.

          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.

                                                                               9
<PAGE>

          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 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

 10
<PAGE>

          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

                                                                              11
<PAGE>

          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 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

 12
<PAGE>

          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

                                                                              13

          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 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 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

                                                                              15

          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 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.

 16
<PAGE>

          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

                                                                              17
<PAGE>

          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 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. 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.

                                                                              19
<PAGE>

          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 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

 20
<PAGE>

          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 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

                                                                              23

          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
          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:

</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

      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:

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

 36
<PAGE>

          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 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.

                                                                              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
          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 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

 42
<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.

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

          The yield for the 30-day period ending December 31, 1999, for the
          Shares of the following Portfolios is shown below:

          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.

          ("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 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.

                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.

                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

 2
<PAGE>

          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.

          (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

                                                                               3
<PAGE>

          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.

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 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

                                                                               5
<PAGE>

          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 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

 6
<PAGE>

          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
          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

                                                                               7
<PAGE>

          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 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

 8
<PAGE>

          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. 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 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 5.70% and 5.86%, 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 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

                                                                              13

          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 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

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

 26
<PAGE>

          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 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
          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

                                                                              29
<PAGE>

          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 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

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

                                                                              31
<PAGE>

          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 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

 32
<PAGE>

          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

CLASSIFICATION, PORTFOLIO TURNOVER, INVESTMENT POLICIES
AND RESTRICTIONS, AND INVESTMENT STRATEGIES AND RISKS
- --------------------------------------------------------------------------------


CLASSIFICATION

          The 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, and
          the Portfolio is a nondiversified fund.

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 the Portfolio's
          securities.

INVESTMENT POLICIES AND RESTRICTIONS

          The Portfolio is 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 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 fundamental policies, the
          Portfolio 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 its total
          assets, 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 the Portfolio in the securities
          of such issuer exceeds 5% of the value of the Portfolio's total
          assets. With respect to the other 50% of the value of its total
          assets, the 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).

          (3) Invest directly in real estate or interests in real estate;
          however, the Portfolio 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 Portfolio 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 the 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, the 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 the Portfolio.

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

          (a) The 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 the 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 the Portfolio's
          commitments under outstanding futures contracts positions would exceed
          the market value of its total assets.

          (b) The Portfolio does not currently intend to sell securities short,
          unless it owns or has 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 Portfolio does not currently intend to purchase securities on
          margin, except that the Portfolio 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) The Portfolio may not mortgage or pledge any securities owned or
          held by the 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 Portfolio may borrow money for temporary or emergency purposes
          (not for leveraging or investment) in an amount not exceeding 25% of
          the value of its 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 Portfolio does 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 Portfolio's 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 Portfolio may not invest in companies for the purpose of
          exercising control of management.

                                                                               3
<PAGE>

          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 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. 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.

INVESTMENT STRATEGIES AND RISKS

Cash Position

          As discussed in the Prospectus, when the portfolio manager believes
          that market conditions are unfavorable for profitable investing, or
          when he is otherwise unable to locate attractive investment
          opportunities, the Portfolio's investment in cash and similar
          investments may increase. Securities that the Portfolio 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 Portfolio may also invest in money
          market funds, including funds managed by Janus Capital. (See
          "Investment Company Securities" on page 7).

Illiquid Investments

          The 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 Portfolio. 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 the 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, the portfolio manager may
          not be able to dispose of them in a timely manner. As a result, the
          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 the Portfolio to decline.

Securities Lending

          The Portfolio 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 Portfolio 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 Portfolio
          will not have the right to vote on securities while they are being
          lent, but they will 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 Securities and Exchange Commission and
          policies approved by the Trustees. Cash collateral may be invested in
          money market funds advised by Janus Capital to the extent consistent
          with exemptive relief obtained from the SEC.

Short Sales

          The Portfolio may engage in "short sales against the box." This
          technique involves selling either a security that the 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. The 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, the
          Portfolio loses the opportunity to participate in the gain.

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

          The Portfolio may invest up to 10% 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.

          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"), the Portfolio must
          distribute its investment company taxable income, including the
          original issue discount accrued on zero coupon or step coupon bonds.
          Because the 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 the Portfolio may have to distribute cash
          obtained from other sources in order to satisfy the distribution
          requirements under the Code. The Portfolio might obtain such cash from
          selling other portfolio holdings which might cause the Portfolio to
          incur capital gains or losses on the sale. Additionally, these actions
          are likely to

                                                                               5
<PAGE>

          reduce the assets to which Portfolio expenses could be allocated and
          to reduce the rate of return for the 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 Portfolio 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 Portfolio. 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. The
          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
          Portfolio), 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

 6
<PAGE>

          sooner. Thus, the security holders frequently receive prepayments of
          principal in addition to the principal that is part of the regular
          monthly payments. The portfolio manager will consider estimated
          prepayment rates in calculating the average-weighted maturity of the
          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 the Portfolio might be converted to cash and the 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 the 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 Portfolio may invest in securities of other
          investment companies, 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.

Depositary Receipts

          The Portfolio 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 Portfolio 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 represent ownership of underlying securities issued by a
          foreign or U.S. securities market. EDRs and GDRs are similar 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 Portfolio's prospectus.

                                                                               7

Municipal Obligations

          The Portfolio 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 the 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 Portfolio 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 have variable or floating rates of interest and, under
          certain limited circumstances, may have varying principal amounts.
          Variable and floating rate 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
          "underlying index"). See also "Inverse Floaters."

          In order to most effectively use these investments, the 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, the 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 the Portfolio the option to obligate a broker, dealer or bank to
          repurchase a security held by the Portfolio at a specified price.

          TENDER OPTION BONDS. Tender option bonds are generally long-term
          securities that are coupled with the 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.

          INVERSE FLOATERS. Inverse floaters are debt instruments whose interest
          bears an inverse relationship to the interest rate on another
          security. The Portfolio will not 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, the Portfolio 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.

<PAGE>

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

High-Yield/High-Risk Bonds

          The Portfolio intends to invest less than 35% of its net assets 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.). 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, the Portfolio would experience a reduction in its income, and
          could expect a decline in the market value of the bonds so affected.

          The 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. Sovereign debt of foreign
          governments is generally rated by country. Because these ratings do
          not take into account individual factors relevant to each issue and
          may not be updated regularly, Janus Capital may treat such securities
          as unrated debt. Because of the size and perceived demand of the
          issue, among other factors, certain municipalities may not incur the
          costs of obtaining a rating. The 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 the Portfolio unless the portfolio
          manager deems such securities to be the equivalent of investment grade
          bonds.

          Subject to the above limits, the 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 the Portfolio generally
          will purchase securities for which its portfolio manager expects 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 Portfolio will limit holdings of any such
          securities to amounts that the portfolio manager believes could be
          readily sold, and holdings of such securities would, in any event, be
          limited so as not to limit the Portfolio's 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 Portfolio.

                                                                               9

Repurchase and Reverse Repurchase Agreements

          In a repurchase agreement, the 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 the 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, the 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 Portfolio to limit repurchase agreements to those
          parties whose creditworthiness has been reviewed and found
          satisfactory by Janus Capital.

          The 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, the
          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, the Portfolio will maintain cash and
          appropriate liquid assets in a segregated custodial account to cover
          its obligation under the agreement. The Portfolio 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.

Futures, Options and Other Derivative Instruments

          FUTURES CONTRACTS. The Portfolio 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 Portfolio's 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

 10
<PAGE>

          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
          the Portfolio, the Portfolio may be entitled to return of margin owed
          to the 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 Portfolio does business and by depositing margin payments in a
          segregated account with the Portfolio's custodian.

          The Portfolio intends 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 Portfolio will use
          futures contracts and related options primarily for bona fide hedging
          purposes within the meaning of CFTC regulations. To the extent that
          the Portfolio holds 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 the Portfolio's net assets, after taking into account unrealized
          profits and unrealized losses on any such contracts it has entered
          into.

          Although the Portfolio will segregate cash and liquid assets in an
          amount sufficient to cover its open futures obligations, the
          segregated assets would be available to the Portfolio immediately upon
          closing out the futures position, while settlement of securities
          transactions could take several days. However, because the 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, the 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 the 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, the 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 the Portfolio not participating in a market
          advance. This technique is sometimes known as an anticipatory hedge.
          To the extent the Portfolio enters into futures contracts for this
          purpose, the segregated assets maintained to cover the 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 the Portfolio with respect to the
          futures contracts. Conversely, if the 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.
          The 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 the Portfolio owns bonds and the portfolio manager expects interest
          rates to increase, the Portfolio may take a short position in interest
          rate futures contracts. Taking such a position would have much the
          same effect as the Portfolio selling bonds in its portfolio. If
          interest rates increase as anticipated, the value of the bonds would
          decline, but the value of the Portfolio's interest rate futures
          contract will increase, thereby

                                                                              11
<PAGE>

          keeping the net asset value of the Portfolio from declining as much as
          it may have otherwise. If, on the other hand, the portfolio manager
          expects interest rates to decline, the 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
          the 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 the
          portfolio manager still may not result in a successful use of futures.

          Futures contracts entail risks. Although the Portfolio believes that
          use of such contracts will benefit the Portfolio, the Portfolio's
          overall performance could be worse than if the Portfolio had not
          entered into futures contracts if the portfolio manager's investment
          judgement proves incorrect. For example, if the Portfolio has hedged
          against the effects of a possible decrease in prices of securities
          held in its portfolio and prices increase instead, the 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 the 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 the 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 the Portfolio will not match exactly the
          Portfolio's current or potential investments. The 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 the Portfolio's investments.

          Futures prices can also diverge from the prices of their underlying
          instruments, even if the underlying instruments closely correlate with
          the 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 the
          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

 12
<PAGE>

          fluctuation limits for futures contracts. The 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 the 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 the 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 the 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, the
          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, the Portfolio's access to other assets held to
          cover its futures positions also could be impaired.

          OPTIONS ON FUTURES CONTRACTS. The Portfolio may buy and write put and
          call options on futures contracts. An option on a future gives the
          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 the
          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, the Portfolio will retain the full amount
          of the option premium which provides a partial hedge against any
          decline that may have occurred in the 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, the Portfolio will retain the full amount of
          the option premium which provides a partial hedge against any increase
          in the price of securities which the Portfolio is considering buying.
          If a call or put option the Portfolio has written is exercised, the
          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, the Portfolio's losses from existing
          options on futures may to some extent be reduced or increased by
          changes in the value of portfolio securities.

                                                                              13
<PAGE>

          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, the 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 the 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 Portfolio 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 Portfolio's principal uses of
          forward foreign currency exchange contracts ("forward currency
          contracts"). The Portfolio may enter into forward currency contracts
          with stated contract values of up to the value of the 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). The 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"). The
          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. The 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 the 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 the 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 the Portfolio's currency
          exposure from one foreign currency to another removes the Portfolio's
          opportunity to profit from increases in the value of the original
          currency and involves a risk of increased losses to the Portfolio if
          its

 14
<PAGE>

          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 the Portfolio than
          if it had not entered into such contracts.

          The Portfolio 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 the Portfolio is not able to
          cover its forward currency positions with underlying portfolio
          securities, the Portfolio's custodian will segregate cash or other
          liquid assets having a value equal to the aggregate amount of the
          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, the 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 the Portfolio's commitments with respect to such
          contracts. As an alternative to segregating assets, the Portfolio may
          buy call options permitting the Portfolio to buy the amount of foreign
          currency being hedged by a forward sale contract or the 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 Portfolio's ability to utilize forward contracts
          may be restricted. In addition, the 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 Portfolio 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, the Portfolio may buy put options on
          the foreign currency. If the value of the currency declines, the
          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, the 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 the 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, the Portfolio could sustain
          losses on transactions in foreign currency options that would require
          the Portfolio to forego a portion or all of the benefits of
          advantageous changes in those rates.

          The Portfolio 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, the 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.

                                                                              15
<PAGE>

          Similarly, instead of purchasing a call option to hedge against a
          potential increase in the U.S. dollar cost of securities to be
          acquired, the Portfolio could write a put option on the relevant
          currency which, if rates move in the manner projected, should expire
          unexercised and allow the 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
          the 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, the Portfolio
          also may lose all or a portion of the benefits which might otherwise
          have been obtained from favorable movements in exchange rates.

          The Portfolio may write covered call options on foreign currencies. A
          call option written on a foreign currency by the Portfolio is
          "covered" if the 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 the 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 the Portfolio in cash or other liquid assets in a
          segregated account with the Portfolio's custodian.

          The Portfolio 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 the 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, the 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 Portfolio 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 Portfolio may write and buy
          options on the same types of securities that the Portfolio may
          purchase directly.

          A put option written by the Portfolio is "covered" if the 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
          Portfolio's 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 the Portfolio is "covered" if the 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 Portfolio's custodian) upon conversion or
          exchange of other securities held in its portfolio. A call option is
          also deemed to be covered if the 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

 16
<PAGE>

          the call written or (ii) is greater than the exercise price of the
          call written if the difference is maintained by the Portfolio in cash
          and other liquid assets in a segregated account with its custodian.

          The Portfolio also may write call options that are not covered for
          cross-hedging purposes. The 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. The
          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 the 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 the 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 the Portfolio
          to use the cash or proceeds from the concurrent sale of any securities
          subject to the option for other investments. If the Portfolio desires
          to sell a particular security from its portfolio on which it has
          written a call option, the Portfolio will effect a closing transaction
          prior to or concurrent with the sale of the security.

          The 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. The 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 the Portfolio.

                                                                              17
<PAGE>

          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 the 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.

          The Portfolio may write options in connection with buy-and-write
          transactions. In other words, the 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, the Portfolio's maximum gain will be the premium
          received by it for writing the option, adjusted upwards or downwards
          by the difference between the 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 the
          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, the Portfolio may elect to close the position or
          take delivery of the security at the exercise price and the
          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.

          The Portfolio may buy put options to hedge against a decline in the
          value of its portfolio. By using put options in this way, the
          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.

          The 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 the Portfolio upon exercise of the
          option, and, unless the price of the underlying security rises
          sufficiently, the option may expire worthless to the Portfolio.

          EURODOLLAR INSTRUMENTS. The 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. The 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. The 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 the
          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 the
          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 Portfolio's custodian. If the 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. The 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, the 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 the
          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 the Portfolio. These transactions may in
          some instances involve the delivery of securities or other underlying
          assets by the 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 the Portfolio is
          contractually obligated to make. If the other party to an interest
          rate swap that is not collateralized defaults, the Portfolio would
          risk the loss of the net amount of the payments that it contractually
          is entitled to receive. The 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
          Portfolio in futures contracts, options on foreign currencies and

                                                                              19
<PAGE>

          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 the 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 the 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.

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 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 Portfolio.

          The Portfolio pays 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 Agreement,
          Janus Capital furnishes certain other services, including net asset
          value determination, portfolio accounting and recordkeeping, for which
          the Portfolio may reimburse Janus Capital for its costs.

          The Portfolio has agreed to compensate Janus Capital for its services
          by the monthly payment of a fee at the annual rate of 0.65% of the
          Portfolio's average daily net assets.

          Janus Capital has agreed to reimburse Strategic Value 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.

          The Advisory Agreement is dated December 14, 1999 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 Agreements or interested
          persons of any such party, and by either a majority of the outstanding
          voting shares or the Trustees of the Portfolio. 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 of the Portfolio, 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 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 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 the

                                                                              21

          SEC, the Portfolio 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.

          The portfolio manager is not permitted to purchase and sell securities
          for his 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 Portfolio, 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 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
- --------------------------------------------------------------------------------


          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 Portfolio. State Street and the foreign subcustodians
          it selects, have custody of the assets of the Portfolio held outside
          the U.S. and cash incidental thereto. The custodian and subcustodian
          hold the Portfolio's assets in safekeeping and collect and remit 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.

          The Portfolio pays DST Systems, Inc., a subsidiary of KCSI, license
          fees at the annual rate of $3.06 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."

          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.

                                                                              23

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. The Portfolio 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 the
          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.

<PAGE>

          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 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 Portfolio.
          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 the 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 Portfolio's 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.

                                                                              25

          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.

          Because the Portfolio has not commenced operations as of the date of
          this prospectus, the Trustees have not received compensation from the
          Portfolio yet. The following table shows the aggregate compensation
          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.

SHARES OF THE TRUST
- --------------------------------------------------------------------------------

NET ASSET VALUE DETERMINATION

          As stated in the Prospectus, the net asset value ("NAV") of the Shares
          of the 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 the
          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 the Portfolio is
          determined by dividing the total value of a Portfolio's securities and
          other assets, less liabilities, attributable to the Shares of the
          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 Portfolio are traded
          primarily in the over-the-counter market. Valuations of such
          securities are furnished by one or more pricing services employed by
          the Portfolio 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. The 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 the Portfolio's NAV is not calculated. The 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 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 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 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 prospectus for your insurance company's
          separate account or your plan documents contain detailed information
          about investing in the Portfolio.

REDEMPTIONS

          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 NAV of the Portfolio during any 90-day
          period for any one shareholder. Should redemptions by any shareholder
          exceed such limitation, the 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 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.

                                                                              31

INCOME DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAX STATUS
- --------------------------------------------------------------------------------


          It is a policy of the Shares of the Portfolio to distribute
          substantially all of its respective investment income at least
          semi-annually and its respective net realized gains, if any, at least
          annually. The Portfolio intends to qualify as a regulated investment
          company by satisfying certain requirements prescribed by Subchapter M
          of the Internal Revenue Code ("Code"). In addition, the 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 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.

          The Portfolio 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 Portfolio
          if these instruments appreciate in value, the Portfolio may make
          various elections permitted by the tax laws. However, these elections
          could require that the Portfolio recognize taxable income, which in
          turn must be distributed, before the securities are sold and before
          cash is received to pay the distributions.

          Some foreign securities purchased by the Portfolio 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
          Portfolio 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 the Portfolio which will reduce its investment
          company taxable income.

          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.

MISCELLANEOUS INFORMATION
- --------------------------------------------------------------------------------


          The 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 the Portfolio are fully paid and
          nonassessable when issued. Shares of the Portfolio participate equally
          in dividends and other distributions by the shares of 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 offers two 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, Service Shares, is 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.

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 the Portfolio or class only
          if a matter affects or requires the vote of only the Portfolio or
          class or the 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 the
          Portfolio's policies and objectives; the Trustees oversee the
          operation of the 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

                                                                              33

          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 above in "Shareholder Meetings," each share of the
          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. The Portfolio or class of the Trust will
          vote separately only with respect to those matters that affect only
          the 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.

INDEPENDENT ACCOUNTANTS

          PricewaterhouseCoopers LLP, 950 Seventeenth Street, Suite 2500,
          Denver, Colorado 80202, independent accountants for the Portfolio,

          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 Portfolio 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 the
          Portfolio will be expressed in terms of the average annual compounded
          rate of return of a hypothetical investment in the Shares of the
          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 the Portfolio on an annual basis, and assume that all
          dividends and distributions are reinvested when paid.

          From time to time in advertisements or sales material, the Portfolio
          may discuss its 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
          Portfolio may also compare its 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 S&P 500 Index, the Dow
          Jones Industrial Average, and the NASDAQ composite. In addition, the
          Portfolio may compare its total return or yield to the yield on U.S.
          Treasury obligations and to the percentage change in the Consumer
          Price Index. Such performance ratings or comparisons may be made with
          funds that may have different investment restrictions, objectives,
          policies or techniques than the Portfolio and such other funds or
          market indicators may be comprised of securities that differ
          significantly from the Portfolio's investments.

                                                                              35

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.
