market instruments.

consistent with reasonable concern for safety of principal by investing
primarily in investment grade corporate debt securities and U.S. Government

policies, and is managed separately by the investment adviser, CIGNA
Investments, Inc. ("CIGNA Investments").  The investment objective of each
Fund is deemed to be a fundamental policy which may not be changed without the

thrift plans, as well as 403(b) custodial accounts for non-profit educational
and charitable organizations. In addition, the retail class is also offered to
Individual Retirement Accounts ("IRAs"), Rollover IRAs, Simplified Employee
Pension Plans and individual investors. Shares of the retail class are offered
to those investors who require or desire additional shareholders services that
are not provided to shareholders of the institutional class. Retail class
shareholders pay the costs associated with the provision of these services.
Please refer to "Purchase and Redemption of Shares" in this Prospectus for a
description of how to purchase and redeem shares of a Fund.

Each Fund has its own distinct investment objective. These objectives are
described in more detail under the heading "Investment Objectives." Although
each Fund will be managed by experienced professionals, there can be no
assurance that the objectives will be achieved.

There are levels of risk involved with each Fund. For fixed income securities,
there is the risk that interest rates will change, thereby affecting the value
of the securities. Generally, the value of fixed income securities declines as
interest rates rise, and conversely, their value rises as interest rates
decline. There is also a credit risk; that is, a risk related to the financial
ability of an issuer to make periodic interest payments and ultimately repay the
principal at maturity. For equity securities, there is the market risk
associated with movement of the stock market in general. In addition, there is
the financial risk related to earnings stability and overall financial soundness
of individual issuers and of issuers collectively which are a part of a
particular industry. For foreign securities, there are additional risks
associated with currency values, the political and regulatory environment, and
overall economic factors in the countries in which a Fund invests. See "Certain
Investment Strategies and Policies" for a discussion of these risks.

CIGNA Funds are "no-load" investments, which means there are no sales charges
or commissions.  CIGNA Funds have no 12b-1 plan or deferred sales charges.

CIGNA Investments, the Funds' adviser, provides each Fund with investment advice
and other services. Each Fund pays CIGNA Investments a management fee for the
management of investments and business affairs. For a discussion of these
services, please see "Management of the Funds."

 -------------------------------------------
 /1/For a more complete description of the Management Fees, see "Management of
 the Funds." CIGNA Investments, the Funds' investment adviser, has voluntarily
 agreed, as to each Fund, to reimburse such portion of its management fee as is
 necessary to cause the Total Fund Operating Expenses of each class of each Fund
 (exclusive of certain expenses) not to exceed the percentages of average daily
 net asset value of each class of each Fund as set forth above as Total Fund
 Operating Expenses.
    
 If this reimbursement is not sufficient to cause the Total Fund Operating
 Expenses of any class of each Fund not to exceed the applicable percentage of
 average daily net asset value, CIGNA Investments, Inc. has agreed to pay such
 other expenses of the applicable Fund as is necessary to keep Total Fund
 Operating Expenses from exceeding the applicable percentage. These arrangements
 will continue in effect until April 30, 1998, and afterwards to the extent
 described in the Funds' then current prospectus. To the extent management fees
 are reimbursed by CIGNA Investments, Inc., or expenses of a Fund are paid by
 CIGNA Investments, Inc., the total return to shareholders will increase. Total
 return to shareholders will decrease to the extent management fees are no
 longer reimbursed or expenses of a Fund are no longer paid.

 /2/Total Fund Operating Expenses for the Money Market Fund, Income Fund and
 International Stock Fund for 1996, before expense reimbursement, were .69%,
 5.62% and 2.61% respectively, of their average daily Net Asset values. Other
 Operating Expenses for all other Funds are based on estimated amounts for the
 current fiscal year, after expense reimbursements. Absent the voluntary expense
 limitations, estimated Other Operating Expenses and Total Fund Operating
 Expenses (assuming average daily net assets of $5,000,000 per Fund) as a
 percentage of average daily Net Asset Values would be as follows, respectively:
 Treasury Obligations Cash - 2.57%, 2.92%; Government Obligations Cash - 2.57%,
 2.92%; Government Securities - 2.54%, 3.04%; High Yield - 2.53%, 3.28%; S&P 500
 Index - 2.62%, 2.87%. It is not expected that Total Fund Operating Expenses
 (absent voluntary expense limitations) would materially vary between classes
 until the classes have a substantial number of shareholders.

Example of Fund Expenses:

The following example illustrates the expenses that you would pay on a $1,000
investment over various time periods assuming (1) a 5% annual rate of return,
and (2) redemption at the end of each time period. As noted above, the Funds
charge no redemption fees of any kind.

The purpose of the Expense Table is to assist the investor in understanding the
various costs and expenses that an investor will bear directly or indirectly.
For the purpose of the example, assume reinvestment of all dividends and
distributions. This example assumes that the estimated voluntary expense
limitations effective in 1997 would be in place for the entire periods
indicated. CIGNA Investments has reserved the right to terminate or revise these
limitations at any time after April 30, 1998. The Example should not be
considered a representation of past or future expenses. Actual expenses may be
greater or less than those shown.

Total Fund Operating Expenses for each Fund's retail class are higher than the
Total Fund Operating Expenses for each Fund's institutional class due to the
costs associated with providing retail class shareholders with additional
services. Please refer to "Management of the Funds - Service Expenses - Retail
Shares" for a more complete description of these services.

**  Commencement of operations.
*** For fiscal years beginning on or after September 1, 1995, a fund is
    required to disclose its average commission rate per share for security
    trades on which commissions are charged. This amount may vary from period to
    period and fund to fund depending on the mix of trades executed in various
    markets where trading practices and commission rule structures may 
    differ.

       ABOUT THE FUNDS
       -----------------------------------------------------------------

       CIGNA International Stock Fund is a series of CIGNA Institutional Funds
       Group, a Massachusetts business trust established by a Master Trust
       Agreement dated as of August 10, 1992 and registered under the 1940 Act
       as an open-end management investment company.  The rest of the Funds are
       separate series of shares of CIGNA Funds Group, a Massachusetts business
       trust established by a Master Trust Agreement dated April 10, 1985, and
       registered under the 1940 Act as an open-end management investment
       company. (See "The Trusts, Their Shares and Board of Trustees").  CIGNA
       Funds Group was formerly known as CIGNA Annuity Funds Group.  Each Fund
       is a mutual fund, an investment that pools shareholders' money and
       invests it toward a specified goal.
    
       Each Fund intends to qualify as a regulated investment company for
       Federal Income Tax purposes.  Each Fund has its own investment objective
       and policies designed to meet specific investment goals.  The Funds
       continuously offer new shares for sale and stand ready to redeem their
       outstanding shares at their net asset value.  The Funds' investment
       adviser, CIGNA Investments, and, where applicable, each sub-adviser,
       continuously review and, from time to time, change the portfolio holdings
       of the Funds in pursuit of each Fund's objective.     

       INVESTMENT PROGRAMS
       -----------------------------------------------------------------
       Money Market Fund

       The Fund's objective is to provide as high a level of current income as
       is consistent with the preservation of capital and liquidity and the
       maintenance of a stable $1.00 per share net asset value by investing in
       short-term money market instruments.  The Fund intends to invest in money
       market instruments such as U.S. Government direct obligations and U.S.
       Government agencies' securities.  In addition, the Fund may invest in
       other money market instruments such as bankers' acceptances, certificates
       of deposit, commercial loan participations, repurchase agreements, time
       deposits and commercial paper, all of which will be denominated in U.S.
       dollars.  Bankers' acceptances, certificates of deposit and time deposits
       may be purchased from U.S. or foreign banks.  Commercial paper is
       purchased primarily from U.S. issuers but may be purchased from foreign
       issuers so long as it is denominated in U.S. dollars.  All of these
       instruments, including commercial loan participations, are briefly
       described 

                                       13
<PAGE>
 
       in the Appendix under "Description of Money Market Instruments" and are
       described more fully in the Statement of Additional Information.

    
       Pursuant to procedures adopted by the Board of Trustees, the Fund may
       purchase only high quality securities that CIGNA Investments believes
       present minimal credit risks.  To be considered high quality, a security
       must be a U.S. Government security or must be rated in accordance with
       applicable rules in one of the two highest categories for short-term
       securities by at least two nationally recognized rating services (or by
       one, if only one rating service has rated the security) or, if unrated,
       judged to be of equivalent quality by CIGNA Investments.     
    
       High quality securities are divided into "first tier" and "second tier"
       securities.  First tier securities have received the highest rating (e.g.
       Standard & Poor's Corporation's ("S&P") A-1 rating) from at least two
       rating services (or one, if only one has rated the security).  Second
       tier securities have received ratings within the two highest categories
       (e.g., S&P's A-1 or A-2) from at least two rating services (or one, if
       only one has rated the security), but do not qualify as first tier
       securities.  If a security has been assigned different ratings by
       different rating services, at least two rating services must have
       assigned the highest of the ratings in order for CIGNA Investments to
       determine eligibility on the basis of that highest rating.  Based on
       procedures adopted by the Board of Trustees, CIGNA Investments may
       determine that an unrated security is of equivalent quality to a rated
       first or second tier security.     

       The Fund may not invest more than 5% of its total assets in second tier
       securities.  In addition, the Fund may not invest more than 1% of its
       total assets or $1 million (whichever is greater) in the second tier
       securities of a single issuer.

       Treasury Obligations Cash Fund

       The Fund's objective is to provide as high a level of current income as
       is consistent with the preservation of capital and liquidity and the
       maintenance of a stable $1.00 per share net asset value by investing in
       short-term U.S. Treasury bills, notes and bonds and other direct
       obligations of the U.S. Treasury.  The Fund may also enter into
       repurchase agreements relating to these obligations.

       Government Obligations Cash Fund

       The Fund's objective is to provide as high a level of current income as
       is consistent with the preservation of capital and liquidity and the
       maintenance of a stable $1.00 per share net asset value by investing in a
       portfolio of short-term U.S.

                                       14

       Government securities. These instruments are either issued or guaranteed
       by the U.S. Government, its agencies, or instrumentalities. These
       securities include, but are not limited to:

            .  direct obligations of the U.S. Treasury, such as U.S. Treasury
               bills, notes, and bonds; and

            .  notes, bonds, and discount notes of U.S. Government agencies or
               instrumentalities, such as the: Farm Credit System, including the
               National Bank for Cooperatives, Farm Credit Banks, and Banks for
               Cooperatives; Federal Home Loan Banks; Federal Home Loan Mortgage
               Corporation; Federal National Mortgage Association; Government
               National Mortgage Association ("GNMA"); and Student Loan
               Marketing Association.

       The Fund may also enter into repurchase agreements relating to these
       obligations.

       Government Securities Fund

       The Fund's objective is to achieve a high level of current income
       consistent with reasonable concern for safety of principal by investing
       in obligations issued, guaranteed or otherwise backed by the U.S.
       Government, its agencies, authorities or instrumentalities.  Under normal
       market conditions, the Fund will invest at least 65% of its total assets
       in these securities.  The securities which may be purchased by the Fund
       include but are not limited to (1) U.S. Treasury obligations such as
       Treasury Bills (maturities of one year or less), Treasury Notes
       (maturities of one to ten years) and Treasury Bonds (generally maturities
       of greater than ten years) and (2) obligations issued, guaranteed or
       otherwise backed by U.S. Government agencies and instrumentalities which
       are supported by any of the following: (a) the full faith and credit of
       the U.S. Treasury (such as obligations of GNMA) (b) the right of the
       issuer to borrow an amount limited to a specific line of credit from the
       U.S. Treasury (such as obligations of the Federal Home Loan Bank) (c) the
       discretionary authority of the U.S. Government to purchase the agency's
       obligations (such as obligations of the Federal National Mortgage
       Association) or (d) the credit of the agency or instrumentality (such as
       obligations of the Student Loan Marketing Association).
    
       The composition and weighted average maturity of the Fund's portfolio
       will vary from time to time, based upon the determination of CIGNA
       Investments of how best to further the Fund's investment objective.  The
       Fund may invest in securities of all maturities, short-term,
       intermediate-term and long-term.     

                                       15

       Income Fund

       The Fund's objective is to provide as high a level of current income as
       possible consistent with reasonable concern for safety of principal by
       investing primarily in investment grade corporate debt securities and
       U.S. Government securities.  Under normal market conditions, the Fund
       will invest at least 65% of its total assets in these securities.  The
       Fund invests in a diversified portfolio of marketable debt securities.
       Up to 55% of the assets of the Fund may be invested in U.S. government
       securities, including securities of U.S. Government agencies or
       instrumentalities.  In addition, the assets of the Fund may be
       invested in money market instruments eligible for purchase by the Money
       Market Fund.

       The Fund also may invest up to 20% of its assets in other fixed-income
       securities, including convertible bonds and preferred stocks, and in
       common stocks and similar equity securities when they are acquired as
       parts of units with fixed-income securities (including warrants or rights
       to purchase equity investments) or upon exercise of such warrants or
       rights or upon the conversion of such securities.  See the Statement of
       Additional Information for a description of warrants.

       The Fund may invest up to 25% of its assets in foreign securities (See
       the description of the International Stock Fund for a discussion of
       foreign securities.).  The Fund will limit its investment in foreign
       securities denominated in foreign currencies to 15% of its total assets.
       Purchases of foreign securities payable in foreign currencies will be
       affected either favorably or unfavorably by changes in the value of the
       foreign currencies against the U.S. dollar.  Investing in foreign
       securities carries increased risk to the Fund (see "Certain Investment
       Strategies and Policies -- Risk Factors Regarding Foreign Securities").

       The Fund may invest up to 20% of its assets in debt securities of less
       than investment grade (i.e., securities rated Ba/BB or below by Moody's
       Investors Services, Inc. ("Moody's") and S&P).  Such securities are
       commonly referred to as junk bonds.  See "Certain Investment Strategies
       and Policies -- Non-Investment Grade Debt Securities" for the risk
       factors associated with investments in such securities.  Investments in
       convertible bonds shall be included in determining this 20% limit.

       Changes in interest rates are likely to result in increases or decreases
       in the value of the investments in the Fund.  The value of the securities
       in this Fund can be expected to vary inversely with the changes in
       prevailing interest rates.  Thus, when interest rates go up, bond prices
       go down, and vice versa.

                                       16

       High Yield Fund

       The Fund's objective is to provide the highest current income attainable
       consistent with reasonable risk through investment primarily in high
       yield, high risk, non-investment grade fixed income securities.  The Fund
       will also consider the possibility of capital growth when it purchases
       and sells securities.
    
       The Fund seeks high income by purchasing principally securities that are
       rated Ba or lower by Moody's or BB or lower by S&P, or securities of
       comparable quality in the opinion of CIGNA Investments that are either
       non-rated or rated by other recognized credit rating agencies.  Under
       normal market conditions, the Fund will invest at least 65% of its total
       assets in these securities.  It should be noted, however, that
       achievement of the Fund's investment objective may be more dependent on
       CIGNA Investments' own credit analysis, and less on that of credit rating
       agencies, than may be the case for funds that invest in more highly rated
       bonds. Under normal market conditions, at least 80% of the value of the
       Fund's total assets will be invested in debt securities, including
       convertible debt securities, warrants and/or cash and cash equivalents.
       The Fund may also invest in preferred stocks.    

       The Fund may invest up to 100% of its assets in debt securities of less
       than investment grade (i.e., securities rated Ba/BB or below by Moody's
       and S&P).  Such securities are commonly referred to as junk bonds.  See
       "Certain Investment Strategies and Policies -- Risk Factors Regarding
       Non-Investment Grade Debt Securities" for the risk factors associated
       with investments in such securities.

       The foregoing Moody's and S&P ratings are described in the Appendix to
       this prospectus.

       While the securities held by the Fund are expected to provide greater
       income and, possibly, opportunity for greater gain than investments in
       more highly rated securities, they may be subject to greater risk of loss
       of income and principal and are more speculative in nature.  The Fund's
       yield and the net asset value of its shares should be expected to
       fluctuate over time.

       International Stock Fund

       The Fund's investment objective is to provide long-term growth of capital
       by investing primarily in common stocks, convertible and non-convertible
       preferred stocks, and convertible debt of companies based outside the
       United States.  Income is an incidental consideration.  For these
       purposes, the phrase "based outside the United States" means companies
       the principal 

                                       17

       headquarters of which are located in a foreign country and which are
       organized under the laws of a foreign country.
    
       CIGNA Investments serves as investment adviser to the Fund, and CIGNA
       International Investment Advisors, Ltd. ("CIIA") serves as sub-adviser.
       See "Management Of The Funds."  In selecting securities for the Fund,
       CIIA will generally seek to allocate the Fund's assets among companies
       based in 8-12 different foreign countries.  It is the present intention
       of CIIA to invest primarily in the securities of companies based in (a)
       countries included in the Morgan Stanley Capital International Europe,
       Australia and Far East Index (the "EAFE Index"), (b) countries which the
       sponsor of the EAFE Index has announced it will include in the EAFE
       Index, and (c) Canada.  As of April 30, 1997, the EAFE Index included the
       following countries:  Australia, Austria, Belgium, Denmark, Finland,
       France, Germany, Hong Kong, Ireland, Italy, Japan, Malaysia, Netherlands,
       New Zealand, Norway, Singapore, Spain, Sweden, Switzerland, and the
       United Kingdom.     

       Under normal conditions the Fund will maintain no less than 65% of its
       total assets in the equity securities of companies based in at least five
       of the aforementioned countries. The 65% figure represents a minimum
       level of investment under normal circumstances. The actual level of
       investment will, of course, fluctuate in accordance with CIIA's
       assessment of market conditions. Ordinarily, the Fund will not invest
       more than 50% of its total assets in the securities of companies based in
       Japan, nor more than 30% of its total assets in the securities of
       companies based in the United Kingdom. The Fund will not ordinarily
       invest more than 25% of its total assets in any other single developed
       country, such as Australia, Canada, France or Germany.
    
       The Fund may invest up to 15% of its total assets in the equity and
       convertible debt securities of companies based in (a) developing
       countries as defined by the Morgan Stanley Capital International Emerging
       Markets Index (Global) (the "Emerging Markets Index"), (b) countries
       which the sponsor of the Emerging Markets Index has announced it will
       include in the Emerging Markets Index, and (c) other countries which, in
       the opinion of CIIA, are generally considered to be an emerging or
       developing country by the international financial community.  As of 
       April 30, 1997, the Emerging Markets Index included the following
       countries: Argentina, Brazil, Chile, China, Columbia, Czech Republic,
       Greece, Hungary, India, Indonesia, Israel, Jordan, Malaysia, Mexico,
       Pakistan, Peru, Philippines, Poland, Portugal, South Africa, South Korea,
       Sri Lanka, Taiwan, Thailand, Turkey, and Venezuela.    
                                       18
<PAGE>
 
       While the Fund intends to invest primarily in the securities of companies
       based in countries included in the EAFE Index and in securities of
       emerging market issuers, it will not necessarily invest its assets
       according to the percentage weightings assigned by any index to a
       particular country or company; the Fund is actively managed and is not an
       index fund.  Since Malaysia is included in both the EAFE Index and is
       regarded as an emerging market, securities of companies based in Malaysia
       will not be included in the 15% limitation noted above.

       The Fund intends to invest principally in the securities of companies
       which CIIA believes possess a strong financial base and have
       opportunities for growth within expanding international economies and
       markets.  In determining the appropriate distribution of investments
       among various countries, CIIA ordinarily considers various factors,
       including, but not limited to:  prospects for relative economic growth;
       expected levels of inflation; relative price levels of the various
       capital markets; government policies influencing business conditions; and
       the range of individual investment opportunities available to the
       international investor.  CIIA's expectations with respect to currency
       movements are also considered in evaluating investment in each country.
       While CIIA does not generally hedge against currency risks, the Fund may
       from time to time engage in foreign exchange transactions to hedge the
       Fund's exposure to changes in foreign currency relative to the U.S.
       dollar.  See "Certain Investment Strategies and Policies -- Foreign
       Exchange Transactions." Once CIIA has determined that a particular
       country has favorable investment characteristics, CIIA seeks to identify
       (a) those economic sectors within the national economy that have the
       potential for strong and sustainable growth and (b) those companies that
       stand to benefit from this expected outcome. In this regard, CIIA seeks
       to focus on long-term political, demographic, and sociological change to
       anticipate important valuation shifts in securities prices.

       In appropriate circumstances, such as when a direct investment by the
       Fund in the securities of a particular country cannot be made or when the
       securities of an investment company are more liquid than the underlying
       portfolio securities, the Fund may, consistent with the provisions of the
       1940 Act, invest in the securities of closed-end investment companies
       that invest in foreign securities.  Since the Fund's shareholders would
       be subject to additional fees, including management fees, for any asset
       so invested, CIIA will invest in such closed-end investment companies
       only where, in its opinion, the potential returns justify incurring the
       additional expense.

       The Fund may invest in convertible preferred stock and convertible debt
       when, in the opinion of CIIA, the yield or conversion price makes
       investment in such instruments more 

                                       19
<PAGE>
 
       attractive than investment in the underlying equity security. The Fund
       will limit investments in convertible debt securities to 10% of the
       Fund's net assets. The Fund will dispose of any bond, as soon as
       practicable consistent with achieving an orderly disposition, that would
       cause the Fund to hold more than 5% of its net assets in bonds rated
       below investment grade (i.e., bonds rated BB or Ba or below by S&P or
       Moody's or, if not so rated, which in the opinion of CIIA are of
       comparable quality).

       Under normal conditions the Fund will maintain 0 - 20% of its total
       assets in government obligations, cash or high quality money market
       instruments (such as banker's acceptances, certificates of deposit, time
       deposits, and commercial paper), each of which may be denominated in U.S.
       dollars or foreign currencies.  The Fund will not invest more than 20% of
       its assets in obligations issued by a single foreign government, its
       agencies and instrumentalities.

       S&P 500 Index Fund

       The objective of the Fund is to achieve long-term growth of capital by
       investing primarily in common stocks of companies in the S&P 500.  The
       Fund will invest in these common stocks in approximately the same
       proportions as they are represented in the S&P 500.  Under normal
       conditions, the Fund will invest at least 80% of its total assets in
       common stocks of companies which compose the S&P 500.  The Fund is
       designed as a long-term investment vehicle.

       The S&P 500 includes 500 selected common stocks, most of which are listed
       on the New York Stock Exchange. Each stock in the S&P 500 has a unique
       weighting, depending on the number of shares outstanding and its current
       price.

       The Fund is subject to market risk -- i.e., the possibility that common
       stock prices will decline over short or even extended periods.  The U.S.
       stock market tends to be cyclical, with periods when stock prices
       generally rise and periods when prices generally decline.
    
       While the Fund seeks to match the performance of the S&P 500, its stock
       portfolio performance may not match that of the S&P 500 exactly.  For
       example, the Fund's performance will reflect deductions for advisory fees
       and other expenses that are not deducted from the performance figures
       reported for the S&P 500.  In addition, while CIGNA Investments generally
       will seek to match the composition of the S&P 500 as closely as possible,
       it may not always invest the Fund's stock portfolio to mirror the S&P 500
       exactly.  For instance, the Fund may at times have its portfolio weighted
       differently from the S&P 500 because of the difficulty and expense of
       executing relatively small stock      

                                       20
<PAGE>
 
   
transactions. Under normal conditions, the Fund anticipates holding at least 480
of the S&P 500 Index issues at all times. The common stock of CIGNA Corporation
is in the S&P 500. CIGNA Investments is an indirect, wholly-owned subsidiary of
CIGNA Corporation. The S&P 500 Index Fund will invest its assets in CIGNA
Corporation stock approximately in proportion to the percentage CIGNA
Corporation stock represents in the S&P 500. CIGNA Corporation and Standard and
Poor's Corporation have no control over each other.     

Pending investment in common stocks of companies in the S&P 500 or to meet
anticipated short-term cash needs such as dividend payments or redemptions of
shares, the Fund may also invest in stock index futures contracts and related
options and in certain short-term fixed income securities (including variable
and floating rate instruments or demand instruments) such as certificates of
deposit, commercial paper, commercial loan participations, bankers' acceptances,
U.S. Government obligations and repurchase agreements.

CERTAIN INVESTMENT STRATEGIES, AND POLICIES
- ------------------------------------------------------------------------
In pursuit of its objectives and policies, one or more of the Funds may employ
one or more of the following strategies in order to enhance investment results:

Money Market Instruments. (All Funds) When deemed appropriate for temporary,
defensive purposes, each of the Funds except the S&P 500 Index Fund may hold
substantially all of its assets in the form of cash or cash equivalent money
market instruments described in the appendix to this prospectus ("Money Market
Instruments."). The S&P 500 Index Fund may invest in Money Market Instruments
pending investment of cash in common stocks or to meet anticipated short-term
cash needs. Of course, the Money Market Funds invest exclusively in Money Market
Instruments.

Regulatory Compliance - Money Market, Treasury Obligations Cash and Government
Obligations Cash Funds (the "Money Market Funds").

The Money Market Funds may follow non-fundamental operational policies that are
more restrictive than their fundamental investment limitations, as set forth in
this prospectus and the Statement of Additional Information, in order to comply
with applicable laws and regulations governing money market funds, including the
provisions of and regulations under the 1940 Act. In particular, the Funds
intend to comply with the various requirements of Rule 2a-7 of the 1940 Act,
which regulates portfolio maturity, quality and diversification. For example,
each Fund will limit its investments to securities with remaining maturities of
397 days or less and will maintain a dollar-weighted average maturity of 90 days
or less. Each Fund will determine the effective maturity of its investments
according to Rule 2a-7. The Funds may change these operational policies to
reflect changes in the laws and regulations without the approval of their
shareholders.

Securities Issued on a When-Issued or Delayed Delivery Basis. (All Funds) Funds
may purchase securities on a "when-issued" basis, that is, delivery of and
placement for the securities is not fixed at the date of purchase, but is set
after the securities are issued (normally within forty-five days after the date
of the transaction). Funds also may purchase or sell securities on a delayed
delivery basis. The payment obligation       

                                       22
<PAGE>
 
and the interest rate that will be received on the delayed delivery securities
are fixed at the time the buyer enters into the commitment. A Fund will only
make commitments to purchase when-issued or delayed delivery securities with the
intention of actually acquiring such securities, but the Fund may sell these
securities before the settlement date if it is deemed advisable.

Investment in securities on a when-issued or delayed delivery basis may increase
a Fund's exposure to market fluctuation and may increase the possibility that
the Fund will incur short-term gains subject to Federal taxation or short-term
losses if the Fund must engage in portfolio transactions in order to honor a
when-issued or delayed delivery commitment. In a delayed delivery transaction,
the Fund relies on the other party to complete the transaction. If the
transaction is not completed, the Fund may miss a price or yield considered to
be advantageous. Each Fund will employ techniques designed to reduce such risks.
If a Fund purchases a when-issued security, the Fund's custodian bank will
segregate cash or high grade securities in an amount equal to the when-issued
commitment. If the market value of the segregated securities declines,
additional cash or securities will be segregated on a daily basis so that the
market value of the segregated assets will equal the amount of the Fund's when-
issued commitments. To the extent cash and securities are segregated, they will
not be available for new investments or to meet redemptions. Securities
purchased on a delayed delivery basis may require a similar segregation of cash
or other high grade securities. For a more complete description of when-issued
securities and delayed delivery transactions see the Statement of Additional
Information.

Dollar Roll Transactions. (Income Fund and Government Securities Fund only) In
order to enhance portfolio returns and manage prepayment risks, the Income Fund
and the Government Securities Fund may engage in dollar roll transactions with
respect to mortgage securities issued by GNMA, FNMA and FHLMC. In a dollar roll
transaction, a Fund sells a mortgage security held in the portfolio to a
financial institution such as a bank or broker-dealer, and simultaneously agrees
to purchase a substantially similar security (same type, coupon and maturity)
from the institution at a later date at an agreed upon price. The mortgage
securities that are purchased will bear the same interest rate as those sold,
but generally will be collateralized by different pools of mortgages with
different prepayment histories. During the period between the sale and purchase,
the Fund will not be entitled to receive interest and principal payments on the
securities sold. Proceeds of the sale will be invested in short-term
instruments, and the income from these investments, together with any additional
fee income received on the sale, could generate income for the Fund exceeding
the yield on the sold security.

                                       23
<PAGE>
 
Dollar roll transactions involve the risk that the market value of the
securities the Fund has committed to purchase may decline below the price of the
securities that the Fund has sold. In the event the buyer of securities in a
dollar roll transaction files for bankruptcy, or becomes insolvent, the Fund's
use of the proceeds from the sale of the securities may be restricted pending a
determination by the other party, or its trustee or receiver, whether to enforce
the Fund's obligation to purchase the securities from the bankrupt party.

Obligations Issued or Guaranteed by U.S. Government Agencies. (Money Market
Fund, Government Obligations Cash Fund, Government Securities Fund and Income
Fund)

Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. Government, such as GNMA participation certificates, are backed by the full
faith and credit of the U.S. Treasury. No assurances can be given that the U.S.
Government will provide financial support to other agencies or
instrumentalities, since it is not obligated to do so. The obligations of these
other agencies and instrumentalities are supported by:

     .  the issuer's right to borrow an amount limited to a specific line of
        credit from the U.S. Treasury (for example, obligations of the Federal
        Home Loan Bank);

     .  discretionary authority of the U.S. government to purchase certain
        obligations of an agency or instrumentality (for example, obligations of
        the Federal National Mortgage Association ("FNMA"); or

     .  the credit of the agency or instrumentality (for example, obligations of
        the Student Loan Marketing Association.

The Funds may invest in mortgage-backed securities, including GNMA Certificates
and pass-through securities issued by FNMA and the Federal Home Loan Mortgage
Corporation ("FHLMC"). GNMA Certificates represent a part ownership in pools of
mortgage loans which are either insured by the Federal Housing Administration or
guaranteed by the Veterans Administration. As mentioned above, the timely
payment of interest and principal on the GNMA Certificates is guaranteed by the
full faith and credit of the U.S. Government. FNMA and FHLMC, which guarantee
payment of interest and principal on their securities, are supervised by the
U.S. Government. Securities issued by FNMA and FHLMC are not backed by the full
faith and credit of the U.S. Government; however, their close relationship with
the U.S. Government makes them high quality securities with minimal credit
risks. Mortgage-backed

                                       24
<PAGE>
 
securities consist of interests in underlying mortgages with maturities of up to
thirty years. Mortgage-backed securities may have maturities shorter than
anticipated if the underlying mortgages are prepaid. This prepayment feature
will make such mortgage-backed securities less effective than other types of
securities as a means of locking in attractive long-term interest rates. This is
caused by the need to reinvest prepayments of principal generally and the
possibility of significant unscheduled prepayments resulting from declines in
mortgage interest rates. At the time principal payments or prepayments are
received by the Fund, prevailing interest rates may be higher or lower than the
current yield of the Fund. As a result, GNMA certificates and other mortgage-
backed securities will have less potential for capital appreciation during
periods of declining interest rates than other investments of comparable
maturities due to the likelihood of increased prepayments of mortgages as
interest rates decline. If the Fund buys mortgage-backed securities at a
premium, mortgage foreclosures and prepayment of principal by mortgagors (which
may be made at any time without penalty) may result in some loss of the Fund's
principal investment to the extent of the premium paid.

       
Illiquid Securities. (All Funds except Government Securities Fund) A Fund may
invest up to 15% of its net assets (10% of the net assets of the Money Market
Funds,) in securities that are illiquid. Illiquid securities include securities
that have no readily available market quotations and cannot be disposed of
promptly (within seven days) in the normal course of business at approximately
the price at which they are valued. Illiquid securities may include securities
that are subject to restrictions on resale because they have not been registered
under the Securities Act of 1933 (the "1933 Act"). Restricted securities may, in
certain circumstances, be resold pursuant to Rule 144A under the 1933 Act, and
thus may or may not constitute illiquid securities. To the extent that qualified
institutional buyers become uninterested in purchasing these restricted
securities the level of illiquidity in a Fund may increase. CIGNA Investments
determines the liquidity of each Fund's investments. Limitations on the resale
of restricted securities may have an adverse effect on their marketability,
which may prevent the Fund from disposing of them promptly at reasonable prices.
The Fund may have to bear the expense of registering such securities for resale,
and the risk of substantial delays in effecting such registrations.     

Investments In Foreign Securities. (All Funds except Government Securities Fund,
Treasury Obligations Cash Fund, Government Obligations Cash Fund and S&P 500
Index Fund) A Fund may invest up to 25% of its total assets (50% for the Money
Market Fund and 100% for the International Stock Fund) in Canadian and other
foreign securities, although the Money Market Fund may only invest in foreign
securities denominated in U.S. dollars and the Income Fund may only invest up to
15% of its total assets in

                                       25
<PAGE>
 
foreign securities denominated in foreign currencies. To the extent it invests
in securities denominated in foreign currencies, a Fund bears the risks of
changes in the exchange rates between U.S. currency and the foreign currency, as
well as the availability and status of foreign securities markets. These Funds
(other than the Money Market Fund) may invest in securities of foreign issuers
which are in the form of American Depositary Receipts ("ADRs"), European
Depositary Receipts ("EDRs") or Global Depository Receipts ("GDRs"), or other
securities representing underlying securities of foreign issuers, and such
investments are treated as foreign securities for purposes of percentage
limitations on investments in foreign securities. ADRs are dollar-denominated
receipts issued generally by a domestic bank and representing the deposit with
the bank of a security of a foreign issuer, and are publicly traded on exchanges
or over the counter in the United States. EDRs are receipts similar to ADRs and
are issued and traded in Europe. GDRs may be offered privately in the United
States and also traded in public or private markets in other countries. For a
discussion of the risks pertaining to investments in foreign securities, see
"Risk Factors Regarding Foreign Securities" below.

Risk Factors Regarding Foreign Securities. (All Funds except Treasury
Obligations Cash Fund, Government Obligations Cash Fund Government Securities
Fund and S&P 500 Index Fund) Investments by a Fund in foreign securities,
whether denominated in U.S. dollars or foreign currencies, may entail all of the
risks set forth below.

     Currency Risk. The value of the Funds' foreign investments will be affected
     by changes in currency exchange rates. The U.S. dollar value of a foreign
     security decreases when the value of the U.S. dollar rises against the
     foreign currency in which the security is denominated, and increases when
     the value of the U.S. dollar falls against such currency.

     Political and Economic Risk. The economies of many of the countries in
     which the Funds may invest may not be as developed as the United States
     economy and may be subject to significantly different forces. Political or
     social instability, expropriation, confiscatory taxation, and limitations
     on the removal of funds or other assets could also adversely affect the
     value of the Funds' investments.

     Regulatory Risk. Foreign companies that are not registered with the
     Securities and Exchange Commission are generally not subject to the
     regulatory controls imposed on United States issuers and, as a consequence,

                                       26
<PAGE>
 
     there is generally less publicly available information about such foreign
     securities than is available about domestic securities. Foreign companies
     are generally not subject to uniform accounting, auditing and financial
     reporting standards, practices and requirements comparable to those
     applicable to domestic companies. Income from foreign securities owned by
     the Funds may be reduced by a withholding tax at the source, which tax
     would reduce dividend income payable to the Funds' shareholders.

     Market Risk. The securities markets in many of the countries in which the
     Funds invest will have substantially less trading volume than the major
     United States markets. As a result, the securities of some foreign
     companies may be less liquid and experience more price volatility than
     comparable domestic securities. Increased custodian costs and other
     administrative costs may be associated with the maintenance of assets in
     foreign jurisdictions. There is generally less government regulation and
     supervision of foreign stock exchanges, brokers and issuers which may make
     it difficult to enforce contractual obligations. In addition, transaction
     costs in foreign securities markets are likely to be higher, since
     brokerage commission rates in foreign countries are likely to be higher
     than in the United States.

     Emerging Markets Risk (International Stock Fund). The risks associated with
     investing in foreign securities are often heightened for investments in
     developing or emerging markets. Moreover, the economies of individual
     emerging market countries may differ favorably or unfavorably from the U.S.
     economy in such respects as the rate of growth in gross domestic product,
     the rate of inflation, capital reinvestment, resource self-sufficiency and
     balance of payments position. Because certain securities of foreign issuers
     that the Fund will hold may be denominated in foreign currencies, the value
     of such securities to the Fund will be affected by changes in currency
     exchange rates and in exchange control regulations. A change in the value
     of a foreign currency against the U.S. dollar will result in a
     corresponding change in the U.S. dollar value of the Fund's securities. In
     addition, some emerging market countries may have fixed or managed
     currencies which are not free-floating against the U.S. dollar. Further,
     certain emerging market countries' currencies may not be internationally
     traded. Certain of these currencies have experienced a steady devaluation
     relative to the U.S. dollar. Many emerging markets countries have
     experienced substantial, and in some periods extremely high, rates of
     inflation for many years. 

                                       27
<PAGE>
 
     Inflation and rapid fluctuations in inflation rates have had, and may
     continue to have, negative effects on the economies and securities markets
     of certain emerging market countries.

Investments by a Fund in ADRs, GDRs, EDRs or similar securities also may entail
some or all of the risks described above.

Foreign Exchange Transactions. (All Funds except Money Market Funds, Government
Securities Fund and S&P 500 Index Fund) Each of these Funds has authority to
deal in foreign exchange between currencies of the different countries in which
it will invest as a hedge against possible variations in the foreign exchange
rates between those countries. This may be accomplished through direct purchases
or sales of foreign currency, purchases of options on futures contracts with
respect to foreign currency, and contractual agreements to purchase or sell a
specified currency at a specified future date (up to one year) at a price set at
the time of the contract. Such contractual commitments may be forward contracts
entered into directly with another party or exchange traded futures contracts.

The Funds may purchase and sell options on futures contracts, forward contracts
or futures contracts which are denominated in a particular foreign currency to
hedge the risk of fluctuations in the value of another currency. Each Fund's
dealings in foreign exchange will be limited to hedging involving either
specific transactions or portfolio positions. Transaction hedging is the
purchase or sale of foreign currency with respect to specific receivables or
payables of the Fund accruing in connection with the purchase or sale of its
portfolio securities, the sale and redemption of shares of the Fund, or the
payment of dividends and distributions by the Fund. Position hedging is the
purchase or sale of foreign currency with respect to portfolio security
positions denominated or quoted in a foreign currency. The Funds will not
speculate in foreign exchange. No Fund will commit a larger percentage of its
total assets to foreign exchange hedges than the percentage of its total assets
which it could invest in foreign securities.

Investments by a Fund in ADRs, GDRs, EDRs or similar securities also may entail
some or all of the risks described above.

Futures Contracts and Related Options. (S&P 500 Index and International Stock
Fund) ("Equity Funds") (High Yield, Government Securities and Income Funds)
("Debt Funds").

The S&P 500 Index Fund may invest in stock index futures having an aggregate
face value of up to 20% of the Fund's total assets in order to simulate full
investment in underlying S&P 500 stocks to obtain full market exposure
immediately upon receiving cash

                                       28
<PAGE>
 
pending investment in common stocks of companies in the S&P 500, to limit
transaction costs should invested assets need to be sold to meet redemption
requests, to limit transaction costs, or to seek higher investment returns when
a futures contract or option is priced more attractively than the underlying
equity security or index. The other Equity Fund may enter into stock index
futures contracts as a hedge against changes in the values of the securities
held or which a Fund intends to purchase. Similarly, each of the Debt Funds may
purchase and sell interest rate futures contracts or purchase and sell options
on such contracts to hedge its portfolio of debt securities against changes in
interest rates. A futures contract on an index (such as the S&P 500) is an
agreement between two parties (buyer and seller) to take or make delivery of an
amount of cash equal to the difference between the value of the index at the
close of the last trading day of the contract and the price at which the index
contract was originally written. In the case of futures contracts traded on U.S.
exchanges, the exchange itself or an affiliated clearing corporation assumes the
opposite side of each transaction (i.e., as buyer or seller). A futures contract
may be satisfied or closed out by delivery or purchase, as the case may be, of
the financial instrument or, in the case of stock index futures contracts, by
payment of the change in the cash value of the index. Frequently, using futures
to effect a particular strategy instead of using the underlying or related
security or index will result in lower transaction costs being incurred.

The Funds may also purchase and write call options and put options on futures
contracts. An option on a futures contract gives the holder the right, in return
for the premium paid, to assume a long position (in the case of a call) or a
short position (in the case of a put) in a futures contract at a specified
exercise price prior to the expiration of the option. Upon exercise of a call
option, the holder acquires a long position in the futures contract and the
writer is assigned the opposite short position. In the case of a put option, the
opposite is true. An option on a futures contract generally may be closed out
(before exercise or expiration) by an offsetting purchase or sale of an option
on a futures contract. See the information set forth below and the Statement of
Additional Information for information on the risks associated with these
investments.

The Funds' use of futures and options thereon will in all cases be consistent
with applicable regulatory requirements and in particular the regulations of the
Commodity Futures Trading Commission relating to exclusions from regulation as a
commodity pool operator. Those regulations currently provide that the Funds may
use commodity futures and option positions (i) for bona fide hedging purposes
without regard to the percentage of assets

                                       29
<PAGE>
 
committed to margin and option premiums, or (ii) for other purposes permitted by
the entity's principal regulator (in the case of the Funds, the Securities and
Exchange Commission) to the extent that the aggregate initial margin and option
premiums required to establish such non-hedging positions do not exceed 5% of
the liquidation value (i.e., the net asset value) of the applicable Fund's
portfolio. For further information regarding futures contracts and options
thereon, see the Statement of Additional Information.

The use of futures contracts and options may involve risks not associated with
other types of instruments which the Funds intend to purchase. In particular, a
Fund's positions in futures contracts and options may be closed out only on an
exchange which provides a liquid secondary market therefor, and there can be no
assurance that a liquid secondary market will exist for any particular futures
contract or option. The inability to close out options and futures positions
could have an adverse impact on a Fund's ability to effectively hedge its
securities and might, in some cases, require a Fund to deposit cash to meet
applicable margin requirements. A Fund's ability to hedge effectively through
transactions in futures contracts or options depends on the degree to which
price movements in its holdings correlate with price movements of the futures
and options. It is possible that there may be an imperfect correlation between
the hedging instrument and the hedged securities, which could result in an
ineffective hedge and a loss to a Fund. See the Statement of Additional
Information for a further description of the Funds' investments in futures
contracts.

Non-Investment Grade Debt Securities. (High Yield Fund and Income Fund). The
High Yield Fund, and to a lesser extent the Income Fund, seek to meet their
respective investment objectives by investing in non-investment grade debt
securities, commonly known as "junk bonds." While generally providing greater
income and opportunity for gain, non-investment grade debt securities may be
subject to greater risks than higher rated securities. Economic downturns tend
to disrupt the market for junk bonds and adversely affect their values. Such
economic downturns may be expected to result in increased price volatility of
junk bonds and of the value of shares of the above-named Funds, and increased
issuer defaults on junk bonds.

In addition many issuers of junk bonds are substantially leveraged, which may
impair their ability to meet their obligations. In some cases, junk bonds are
subordinated to the prior payment of senior indebtedness, which potentially
limits a Fund's ability to fully recover principal or accrued interest or to
receive payments when senior securities are in default.

                                       30
<PAGE>
 
The credit rating of a junk bond does not necessarily address its market value
risk, and ratings may from time to time change to reflect developments regarding
the issuer's financial condition. Junk bonds have speculative characteristics
which are likely to increase in number and significance with each successive
lower rating category.

When the secondary market for junk bonds becomes more illiquid, or in the
absence of readily available market quotations for such securities, the relative
lack of reliable objective data makes it more difficult to value a Fund's
securities, and judgment plays a more important role in determining such
valuations. Increased illiquidity in the junk bond market also may affect a
Fund's ability to dispose of such securities at desirable prices.

In the event a Fund experiences an unexpected level of net redemptions, the Fund
could be forced to sell its junk bonds without regard to their investment
merits, thereby decreasing the asset base upon which the Fund's expenses can be
spread and possibly reducing the Fund's rate of return. Generally, prices of
junk bonds have been found to be less sensitive to fluctuations in interest
rates, and more sensitive to adverse economic changes and individual corporate
developments than those of higher-rated debt securities.

Borrowing. (All Funds). Each Fund may borrow from banks or through reverse
repurchase agreements to the extent permitted by the 1940 Act. If a Fund borrows
money, its share price may be subject to greater fluctuation until the borrowing
is paid off. Under the 1940 Act as currently in effect, a Fund may borrow from
any lender only for temporary purposes in an amount not exceeding 5% of its
total assets, and may borrow from a bank in an amount not exceeding 33 1/3% of
its total assets.

    
Lending of Portfolio Securities. (All Funds). In order to generate additional
income, each Fund may lend its portfolio securities on a short-term or long-term
basis, or both, to broker/dealers, banks, or other institutional borrowers of
securities. Each Fund will only enter into loan arrangements with
broker/dealers, banks, or other institutions which CIGNA Investments or CIIA, as
applicable, has determined are creditworthy under guidelines established by the
Funds' Trustees and will receive collateral at all times equal to at least 100%
of the value of the securities loaned. There is the risk that when lending
portfolio securities, the securities may not be available to the Fund on a
timely basis and the Fund may, therefore, lose the opportunity to sell the
securities at a desirable price. In addition, in the event that a borrower of
securities would file for bankruptcy or become insolvent, disposition of the
securities may be delayed pending court action.      

                                       31
<PAGE>
 
Portfolio Turnover. (All Funds except Money Market Funds and S&P 500 Index
Fund). Any particular security will be sold, and the proceeds reinvested,
whenever such action is deemed prudent from the viewpoint of a Fund's investment
objectives, regardless of the holding period of that security. It is
anticipated, given the S&P 500 Index Fund's policy of attempting to replicate
composition and performance, before expenses, of the S&P 500, that portfolio
turnover will be lower than that of an actively managed fund. A higher rate of
portfolio turnover may result in higher transaction costs, including brokerage
commissions. Also, to the extent that higher portfolio turnover results in a
higher rate of net realized capital gains to a Fund, the portion of the Fund's
distributions constituting taxable capital gains may increase. See "Dividends
and Capital Gains Distributions."

INVESTMENT RESTRICTIONS
- ---------------------------------------------------------------
Each Fund's investment objective, as set forth under "Investment Objectives,"
and the investment restrictions listed below are among each Fund's fundamental
policies, that is, subject to change only by shareholder approval. See the
Statement of Additional Information for other investment restrictions. All
policies stated throughout this prospectus, other than those identified as
fundamental, can be changed without shareholder approval.

A Fund may not:

1.  With respect to 75% of its assets, purchase the securities of any issuer if
    such purchase would cause more than 5% of the value of its total assets
    (taken at market value at the time of such investment) to be invested in the
    securities of such issuer except (a) U.S. Government securities including
    securities issued by its agencies and instrumentalities (or repurchase
    agreements with respect thereto), and (b) with respect to the Money Market
    Funds, to securities or obligations issued by U.S. banks.

2.  With respect to 75% of its assets, purchase the securities of any issuer if
    such purchase would cause more than 5% of the voting securities, or more
    than 10% of the securities of any class of such issuer (taken at the time of
    such investment), to be held by the Fund.

3.  Concentrate 25% or more of its total assets in a particular industry.
    Investing in cash or high quality money market instruments, for temporary
    defensive purposes, securities issued or guaranteed by the U.S. Government,
    its agencies or instrumentalities or repurchase agreements secured by these
    instruments shall not be considered investments in a particular industry. In
    addition, each Money Market Fund 

                                       32
<PAGE>
 
    may invest up to 100% of its assets in the domestic banking industry.

4.  Borrow money, issue senior securities, or pledge, mortgage or hypothecate
    its assets, except that a Fund may (i) borrow to the extent permitted by the
    1940 Act, and pledge, mortgage or hypothecate its assets in connection
    therewith, and (ii) enter into transactions in options, futures and options
    on futures and other derivative instruments (the deposit of assets in escrow
    in connection with the writing of covered put and call options and the
    purchase of securities on a when-issued or delayed delivery basis,
    collateral arrangements with respect to initial or variation margin deposits
    for futures contracts, and commitments entered into under swap agreements or
    other derivative instruments will not be deemed to be pledges of a Fund's
    assets).


PURCHASE AND REDEMPTION OF SHARES
- ---------------------------------------------------------------
General Information

The Funds presently offer two methods of purchasing shares (institutional class
and retail class), enabling the Funds to respond to service needs of different
classes of investors. This structure has been developed to attract large
institutions, retirement plans and individual investors as Fund shareholders so
that certain expenses (such as custodian fees, administrative services, audit
fees, legal fees, fees of trustees unaffiliated with the Funds, regulatory fees
and certain printing expenses) can be shared rather than duplicated, in an
effort to achieve economies of scale.

Institutional Shares

Institutional shares of any Fund will be offered to employer-sponsored
retirement or savings plans, such as tax-qualified pension and profit-sharing
plans and 401(k) thrift plans, as well as 403(b) custodial accounts for non-
profit and charitable organizations; corporations; banks; trust companies;
savings and loan associations; broker-dealers; insurance companies; charitable
foundations; and other institutional investors.

Retail Shares

Retail shares may be purchased by employer-sponsored retirement or savings
plans, individuals, IRAs or any other investor who wants the additional personal
services provided to shareholders of the retail class. The retail class of each
Fund will pay the

                                       33
<PAGE>
 
       costs associated with the additional services provided to retail class
       shareholders.

       HOW TO PURCHASE SHARES

       Shares of each Fund are sold on a continuous basis without any initial
       sales charge or contingent deferred charge at the Fund's net asset value
       per share (see "Pricing of Shares").  The Funds do not issue share
       certificates.

       Retirement and Savings Plan Participants

       One or more of the Funds may be available as investment options in
       employer-sponsored retirement or savings plans.  All orders to purchase
       shares must be made through and in accordance with procedures established
       by the participant's employer or plan administrator.  The plan
       administrator can provide participants with detailed information on how
       to participate in the plan and how to select a CIGNA Fund as an
       investment option.

       Brokerage Account Purchases

       All investors other than employer sponsored retirement or savings plan
       participants must purchase shares through CIGNA Financial Advisors, Inc.
       ("CFA").  Orders placed through your brokerage representative are priced
       as of the close of business on the day the order is received by CIGNA
       Funds Shareholder Services or the transfer agent, provided the order is
       received by 4:00 p.m. Eastern Time.  Brokerage representatives are
       responsible for the prompt transmission of purchase and redemption orders
       placed through them by shareholders.   A completed Application is
       required to establish a new brokerage account.  Purchase orders must be
       accepted by CFA.  CFA reserves the right to reject any purchase order.
       Additional information regarding establishing a brokerage account and
       purchasing shares may be obtained by calling your dealer representative
       at 1-800-XXX-XXXX.

       Additional Information:

       Each Fund reserves the right to limit purchases of shares for any one
       account or related accounts to 2% of the total net asset value of the
       Fund, or may refuse to sell shares of the Fund to any person.

       HOW TO REDEEM SHARES

       Retirement and Savings Plan Participants.

       Plan participants should contact their plan administrator for information
       on how to redeem Fund shares.

                                                                         page 34
<PAGE>
 
       Brokerage Account Redemptions.

       All other investors must redeem shares through their brokerage account
       with CFA.  A signature guarantee may be required before payment can be
       made on redemption orders.  For additional information regarding
       redeeming shares from your brokerage account, call your dealer
       representative at 1-800-XXX-XXXX.

       Further Redemption Information.

       Redemptions from the Funds may not be processed if a redemption request
       is not submitted in proper form.  To be in proper form, the investor must
       furnish a taxpayer identification number and address.  The Funds may be
       required to impose "back-up" withholding of federal income tax on
       dividends, distributions and redemption of proceeds when non-corporate
       investors have not provided a certified taxpayer identification number.
       In addition, if an investor sends a check for the purchase of Fund shares
       and shares are issued before the investor's check has cleared, the
       transmittal of any proceeds from the redemption of the shares will occur
       upon clearance of the check, which may take up to 15 days.

       Each of the Funds reserves the right to suspend the right of redemption
       and to postpone the date of payment upon redemption for up to seven days
       and for such other periods as the 1940 Act or Securities and Exchange
       Commission ("SEC") may permit.

       TELEPHONE SERVICES

       If you are a retirement or savings plan participant and have questions or
       want information about your plan account, contact your plan
       administrator.

       All other investors should call 1-800-XXX-XXXX for account information or
       to speak to their dealer representative.

       MAKING EXCHANGES

       Shares of a Fund may be exchanged for shares of the same class of another
       Fund based on the respective net asset values of the shares involved.  An
       exchange order is treated the same as a redemption followed by a
       purchase.  Each Fund reserves the right to discontinue, alter or limit
       its exchange privilege at any time.

       Retirement and Savings Plan Participants.

       Retirement plans may allow participants to exchange monies from one
       investment option to another.  Plan participants should check 

                                                                         page 35
<PAGE>
 
       with their plan administrator for details on the rules governing
       exchanges in their plan. Exchanges are accepted by the Funds only as
       permitted by the applicable retirement plan. Participants' plan
       administrators can explain how frequently exchanges are allowed.

       Brokerage Accounts

       Shareholders with CFA brokerage accounts may obtain additional
       information regarding exchanging shares in their brokerage account by
       calling their dealer representative at 1-800-XXX-XXXX.


       PRICING OF SHARES
       --------------------------------------------------------------------

       The net asset value of each class of a Fund is calculated by the Funds'
       custodian, State Street, by dividing the number of outstanding shares of
       such class into the net assets of the Fund attributable to that class.
       Net assets are the excess of a Fund's assets over its liabilities. Net
       asset value is determined as of 4:00 p.m. Eastern Time on each day the
       New York Stock Exchange ("NYSE") is open for trading and on any other day
       on which there is a sufficient degree of trading in a Fund's investments
       that the current net asset value of its shares might be materially
       affected. Portfolio securities and other assets are valued on the basis
       of market quotations or, if quotations are not readily available, by a
       method that the Trust's Board of Trustees believes accurately reflects
       fair value. Orders for purchases and redemption will not be processed if
       received when the NYSE is closed. The NYSE is closed on New Year's Day,
       President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
       Thanksgiving Day, and Christmas Day.

       Equity securities, including warrants, that are listed on a securities
       exchange or that are part of the Nasdaq National Market are generally
       valued at the last sale price or, if there has been no sale that day, at
       the last bid price. Debt and other equity securities actively traded in
       the over-the-counter market, including listed securities whose primary
       markets are believed to be over-the-counter, are valued at the most
       recent bid price, which may be based upon valuations furnished by a
       pricing service or from independent securities dealers.  High quality
       short-term investments with remaining maturities of up to and including
       60 days are valued at amortized cost to the extent that it is believed to
       approximate market value.  Except for money market instruments owned by a
       Money Market Fund, which are valued at amortized cost, investments that
       mature in more than 60 days are valued at current market quotations.
       Other securities and assets of a Fund, with the exception of futures
       contracts and options on future contracts, which are discussed below, are
       valued in good faith by, or under the authority of, the Board of Trustees
       of the 

                                                                         page 36

       Trust. The net asset value so computed applies to all purchase
       orders and redemption requests in the hands of State Street Bank and
       Trust Company, the Funds' custodian ("State Street") by 4:00 P.M., duly
       executed in accordance with applicable instructions, on the day of such
       determination. Any orders received after such time are executed at the
       net asset value next determined.

       Futures Contracts

       Initial margin deposits made upon entering into futures contracts are
       recognized as assets due from the broker (the Fund's agent in acquiring
       the futures position). During the period the futures contract is open,
       changes in the value of the contract are recognized as unrealized gains
       or losses by "marking-to-market" on a daily basis to reflect the market
       value of the contract at the end of each day's trading. Variation margin
       payments are made or received, depending upon whether unrealized losses
       or gains are incurred. When the contract is closed, the Fund records a
       realized gain or loss equal to the difference between the proceeds from
       (or cost of) the closing transaction and the Fund's basis in the
       contract.

       Options on Futures Contracts

       The premium paid by a Fund for the purchase of a call or put option on
       futures contracts is recorded as an investment and subsequently "marked-
       to-market" to reflect the current market value of the option purchased.
       The current market value of a purchased option on futures contracts is
       generally the last reported sale price or, if no sales are reported, the
       last bid price. If an option on futures contracts which a Fund has
       purchased expires on the stipulated expiration date, the Fund realizes a
       loss in the amount of the cost of the option. If a Fund exercises a
       purchased put option on a futures contract, it realizes a gain or loss
       from the sale of the underlying futures contract and the proceeds from
       such sale will be decreased by the premium originally paid. If a Fund
       exercises a purchased call option on futures contracts, the cost of the
       futures contract which the Fund purchases upon exercise will be increased
       by the premium originally paid.

       Valuation of Money Market Investments (Money Market Funds)

       Money market investments are generally valued at amortized cost, which
       approximates market value, in accordance with rules adopted by the
       Securities and Exchange Commission.  Using the amortized cost valuation
       method allows the Money Market Funds to maintain their net asset value at
       $1.00 per share.  There is no assurance that this method will always be
       used, or if used, that the net asset value under certain conditions will
       not deviate from $1.00 per share.  If the Board of Trustees deems it
       inadvisable to 

                                                                          page37
<PAGE>
 
       continue the practice of maintaining the net asset value of $1.00 per
       share it may alter this procedure. The shareholders of a Fund will be
       notified prior to any such change, unless such change is only temporary,
       in which case the shareholders will be notified after the change. See the
       Statement of Additional Information for more information on amortized
       cost procedures.

       MANAGEMENT OF THE FUNDS

       =================================================================
           
       The investment adviser to each of the Funds is CIGNA Investments, an
       indirect, wholly-owned subsidiary of CIGNA Corporation. CIGNA Investments
       also serves as investment adviser for other investment companies,
       including investment companies sponsored by affiliates of CIGNA
       Corporation, and for a number of pension, advisory, corporate and other
       accounts. CIGNA Investments and other affiliates of CIGNA Corporation
       manage combined assets of approximately $70 billion. CIGNA Investments'
       mailing address is 900 Cottage Grove Road, Hartford, Connecticut 
       06152.     
               
       Pursuant to a Master Investment Advisory Agreement, the Trust, on behalf
       of the Funds, employs CIGNA Investments to manage the investment and
       reinvestment of the assets of the Funds.     
           
       CIGNA Investments has a sub-advisory agreement with CIIA, an indirect,
       wholly-owned subsidiary of CIGNA Corporation, for the International Stock
       Fund.  CIIA's mailing address is Park House, 16 Finsbury Circus, London,
       England EC2M 7AX     
           
       Subject to the control and periodic review of the Board of Trustees,
       CIGNA Investments (and CIIA with respect to the International Stock Fund)
       determines what investments shall be purchased, held, sold or exchanged
       by the Funds and what portion, if any, of the assets of the Funds shall
       be held in cash and other temporary investments. CIGNA Investments is
       also responsible for overall management of the business affairs of the
       Trust and the Funds.     
           
       As full compensation for the investment management and all other services
       rendered by CIGNA Investments and any sub-adviser, each Fund pays CIGNA
       Investments a separate fee computed daily and paid monthly at annual
       rates based on a percentage of the value of the relevant Fund's average
       daily net assets, as follows: Government Securities Fund - 0.50%,  Income
       Fund - 0.50%; High Yield Fund - 0.75%; S&P 500 Index Fund - 0.25%; Money
       Market Fund - 0.35%; Government Obligations Cash Fund - 0.35%; Treasury
       Obligations Cash Fund - 0.35%, and International Stock Fund - 0.80%.     

                                                                          page38
<PAGE>
 
           
       Each Fund will bear its own expenses.  Operating expenses for each Fund
       generally consist of all costs not specifically borne by CIGNA
       Investments, including investment management fees, fees for necessary
       professional and brokerage services, costs of regulatory compliance,
       compensation of trustees not affiliated with CIGNA Corporation and costs
       associated with maintaining legal existence.  Trust-wide expenses not
       attributable to any particular Fund will be allocated among the Funds on
       a pro rata basis based upon each Fund's average net assets.     
           
       CIGNA Investments has voluntarily agreed, until April 30, 1998, and
       thereafter to the extent described in the Funds' then-current prospectus,
       to reimburse the institutional and retail classes of each Fund to the
       extent that the annual operating expenses in any one year (excluding
       interest, taxes, amortized organizational expense, transaction costs in
       acquiring and disposing of portfolio securities and extraordinary
       expenses) exceed a percentage of the value of average daily net assets,
       as follows:

       CIGNA Investments retains the ability to be repaid by a Fund if expenses
       fall below the specified limit prior to the end of the fiscal year.
       Unless otherwise specified, reimbursement arrangements can be terminated
       without notice.

       CIGNA Investments and CIIA investment personnel may invest in securities
       for their own account pursuant to a code of ethics that establishes
       procedures for personal investing and restricts certain 
       transactions.     

       State Street serves as transfer agent and dividend disbursing agent for
       the Funds. State Street is also custodian of the assets of the Funds.

       From time to time, the Funds may pay brokerage commissions on portfolio
       transactions to brokers who may be deemed to be affiliates of CIGNA
       Corporation under the 1940 Act.  See the Statement of Additional
       Information for further details.

       Service Expenses - Retail Shares

       The retail class of each Fund has adopted a shareholder services plan.
       Under each plan, the retail class of each Fund is authorized to pay CFA,
       its affiliates or independent third-party service providers, up to $30
       per shareholder account per year for providing particular services to the
       shareholders of the retail class of such Fund and/or maintenance of
       retail class shareholder accounts.  The Board of Trustees of the Trusts
       may change the per account charge based upon its assessment of fair and
       reasonable fees.

       Investors who purchase retail class shares of a Fund will receive
       additional shareholder services, described below, that are not provided
       to the institutional class investors.  In return for these services, the
       retail class shares shall bear the expense of the shareholder services
       plan.  Because of the costs associated with the shareholder services
       plan, the performance of the retail class shares of each Fund will be
       lower than the performance of institutional class shares of that Fund.

       Service activities provided by CFA, its affiliates or third-party service
       providers to shareholders of retail class shares of a Fund may include:
       receiving, aggregating and processing shareholder or beneficial owner
       (collectively "shareholder") orders; furnishing shareholder
       subaccounting; providing and maintaining retirement plan records;
       communicating periodically with shareholders; acting as the sole
       shareholder of record and nominee for shareholders; maintaining account
       records for shareholders; answering questions and handling correspondence
       from shareholders about their accounts; issuing various 

                                                                         Page 40
<PAGE>
 
       shareholder reports and confirmations for transactions by shareholders;
       and performing similar account and administrative services. For a more
       complete description of the shareholder services plan and its terms, see
       the Statement of Additional Information.

       Portfolio Management

       The individuals who are primarily responsible for the day-to-day
       management of each of the Funds (other than the Money Market Funds and
       the S&P 500 Index Fund) and their occupations for the past five years are
       described below:

       Distributor

       CFA acts as the principal underwriter and distributor of each Fund's
       shares pursuant to a distribution agreement with the Funds. CFA will pay
       the cost of printing and mailing

                                                                         page 41

       advertising expenses incurred by it in connection with its distribution
       of shares of the Funds.


       PERFORMANCE INFORMATION
       ----------------------------------------------------------------------

       Each Fund's and class's investment performance may from time to time be
       included in advertisements about that Fund.  Mutual fund performance is
       commonly measured as total return and/or yield.

       Total return quotations will, unless otherwise indicated, be calculated
       according to a standard formula described in regulations issued by the
       SEC.  This formula equates an amount invested in a Fund at the beginning
       of a stated period to the value of that investment (assuming reinvestment
       of all dividends and capital gains) at the end of the period.  The
       resulting return quote is an average annual total return across the
       stated period.  Due to the deduction of the shareholder service fee,
       performance of the retail class of each Fund will be lower than the
       performance of the institutional class of each Fund.

       In addition, each Fund may calculate its total return pursuant to non-
       standard formulas (such as a cumulative return across a stated period),
       provided that standard return quotes for the one-, five- and ten-year
       periods (or from the Fund's inception, if shorter) ending no earlier than
       the end of the last calendar quarter are illustrated with equal
       prominence.

       Yield quotations for all Funds will be calculated according to the
       applicable standard formula described in regulations issued by the SEC.
       Yield refers to the income generated by an investment in a fund over a
       given period of time, expressed as an annual percentage rate.  For all
       Funds except the Money Market Funds, the formula is based upon a stated
       30-day period.  Net investment income for the period is divided by the
       maximum offering price on the last day of the period, multiplied by the
       average number of shares outstanding during the period.  The resulting
       figure is then compounded semiannually.  The net investment income for
       this purpose is generally different from net investment income determined
       in accordance with generally accepted accounting principles.

       For the Money Market Funds, the applicable formula is based on a stated
       seven-day period. The change in value of a hypothetical pre-existing
       account across the stated period (assuming reinvestment of dividends) is
       divided by the value of such an account at the beginning of the period.
       The result is then multiplied by 365/7. This yield is an annualized
       yield. The Fund may also calculate its effective annualized yield by
       adding

                                                                         page 42
<PAGE>
 
       "1" to the annualized yield, raising the sum to a power equal to
       365/7, and subtracting "1" from the result.

       Also, each Fund may compare its performance in advertisements, sales
       literature and reports to shareholders to applicable market indices, such
       as the S&P 500, the Dow Jones Industrial Average, the NASDAQ OTC
       Composite or the EAFE Index (Equity Funds), the Shearson Lehman Brothers
       Government/Corporate Bond Index, the Shearson Lehman Brothers High Yield
       Bond Index or the First Boston High Yield Index (Debt Funds) and Donoghue
       Money Market Institutional Averages (Money Market Funds).  Each Fund may
       also compare its performance to performance data of similar mutual funds
       as published by services such as Lipper Analytical Services, Inc.,
       Morningstar, Inc. and Donoghue's Money Fund Average.  Each Fund may also
       include in performance information evaluations of the Fund published by
       nationally recognized financial publications.

                                                                         page 43

       Set forth below are certain performance data relating to all high yield
       bond portfolios which have been managed with full investment authority by
       Alan Petersen, portfolio manager of CIGNA High Yield Fund, and which have
       the same investment objective and use substantially similar investment
       strategies, policies and techniques that are used for CIGNA High Yield
       Fund.  The performance information set forth below reflects past
       performance and is not necessarily indicative of the future performance
       of CIGNA High Yield Fund.

       DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
       ----------------------------------------------------------------
       The Funds declare and distribute dividends representing substantially all
       net investment income as follows:
<TABLE>

                                     Dividends        Dividends

       Government Securities Fund    daily            monthly
       Income Fund                   daily            monthly

</TABLE>

       Substantially all net realized capital gains, if any, are distributed on
       an annual basis, except for the Money Market Funds, which include
       realized gains and losses in their daily declarations of dividends from
       net investment income.

       All such distributions will be automatically reinvested for you in shares
       of the Fund issuing the distribution at the net asset value determined on
       the record date or, if you have so elected on forms approved by the
       Funds, will be paid in cash to you or to someone you designate, either by
       check or automatic deposit into a bank checking account.

       TAX MATTERS
       ----------------------------------------------------------------

       Each Fund intends to qualify under the Internal Revenue Code of 1986, as
       amended (the "Code"), as a regulated investment company ("RIC") for each
       taxable year.  Each Fund intends to satisfy requirements under the Code
       relating to the distribution of net income so that, in general, the Fund
       will not be subject to Federal income tax ("FIT").

       Each Fund is subject to a nondeductible 4% excise tax if it does not meet
       certain distribution requirements under the Code.  The Funds intend to
       make sufficient distributions to avoid this excise tax.

       Distributions of net investment income and of any net short-term capital
       gain are taxable as ordinary income to shareholders, whether received in
       cash or reinvested in shares.  Distributions of net capital gain, if
       properly designated as capital gain dividends by a Fund, generally are
       taxable to shareholders as long-term capital gain, regardless of how long
       the shares have 

                                                                         page 45
<PAGE>
 
       been held, and are not eligible for the corporate dividends-received
       deduction. Distributions of net investment income and net capital gains
       will be taxable as described above whether received in cash or reinvested
       in shares. Shortly after the end of each year, the Fund will inform
       shareholders of the amount and FIT treatment of all distributions paid
       during the year. Dividends declared to shareholders of record on a 
       date in October,November, or December will be taxable to shareholders 
       in the yeardeclared, as long as the Fund pays the dividends no later 
       than January of the following year.

       Upon a sale or redemption of Fund shares, a shareholder who is not a
       dealer in securities will realize gain or loss which generally will be
       treated as long-term capital gain or loss if the shares have been held
       for more than one year, and otherwise as short-term capital gain or loss.
       However, if a shareholder disposes of shares held for six months or less,
       any loss realized will be characterized as long-term capital loss to the
       extent of any capital gain dividends (or undistributed capital gain) made
       (or credited) to such shareholder prior to such disposition.

       Tax-exempt shareholders will generally not be subject to FIT on amounts
       distributed to them.

       Pursuant to the Code and IRS regulations, each Fund will withhold FIT at
       a rate of 31% from ordinary income dividends and capital gain
       distributions, and from redemption payments made to any shareholder who
       fails to furnish a correct taxpayer identification number, or, in certain
       cases, fails to properly report income for FIT purposes.

       Distributions may also be subject to state and local taxes depending on
       each shareholder's tax situation.  Shareholders should consult their tax
       advisers regarding the particular tax consequences of investing in the
       Funds.

       Government Securities Fund:  The Fund generally pays dividends to its
       shareholders based upon its financial statement income.  Certain ordinary
       income dividends may be treated as a return of capital to shareholders
       for tax purposes as a result of different tax and financial statement
       treatments of certain mortgaged-backed securities.  The Fund will inform
       each shareholder of the percentage of dividends received which are
       treated as a return of capital following the end of each year.

       Debt Funds:  For FIT purposes, the Funds report imputed interest on
       certain securities as income, even though a Fund may receive no cash
       interest payments until the securities' maturity or payment dates.

                                                                         Page 46

       THE TRUSTS, THEIR SHARES AND BOARD OF TRUSTEES
       -----------------------------------------------------------------

       The Trusts currently offer eight series of shares. The Board of Trustees
       of the Trusts is authorized in each Trust's Master Trust Agreement to
       create new series of shares without the necessity of a vote of
       shareholders of either Trust. There is a remote possibility that one Fund
       might become liable for a misstatement in the prospectus about another
       Fund. The capitalization of the Trusts consists solely of an unlimited
       number of shares of beneficial interest with a par value of $0.001 each.

       The institutional class and the retail class of the same Fund represent
       interests in that Fund's assets and have identical voting, dividend,
       liquidation and other rights on the same terms and conditions, except
       that each class of shares bears differing class-specific expenses and
       exchange privileges and the retail class has exclusive voting rights on
       matters pertaining to the shareholder services plan.

       Under Massachusetts law, each Trust's shareholders could, under certain
       circumstances, be held personally liable for the obligations of their
       Trust.  However, each Trusts' Master Trust Agreement disclaims liability
       of the shareholders, Trustees or officers of the Trust for acts or
       obligations of the Trust, which are binding only on the assets and
       property of the Trust, and requires that notice of the disclaimer be
       given in each contract or obligation entered into or executed by the
       Trust or the Trustees.  Each Master Trust Agreement provides for
       indemnification out of Trust property for all loss and expense of any
       shareholder held personally liable for the obligations of the Trust.  The
       risk of a shareholder incurring financial loss on account of shareholder
       liability is limited to circumstances in which the Trust itself would be
       unable to meet its obligations and thus should be considered remote.

       Under the Master Trust Agreements no annual or regular meetings of
       shareholders are required. Meetings of shareholders of a series will be
       held from time to time to consider matters requiring a vote of such
       shareholders in accordance with the requirements of the 1940 Act, state
       law or the provisions of the Master Trust Agreement. It is not expected
       that shareholder meetings will be held annually.

       Shares of each Fund will entitle their holders to one vote per share
       (with proportionate voting for fractional shares), irrespective of the
       relative net asset value of the shares of any Fund.  On any matter
       submitted to a vote of shareholders of a Trust, all shares of that Trust
       then issued and outstanding shall be voted in the aggregate.  However, on
       matters affecting an individual Fund or class of shares, a separate vote
       of shareholders of that Fund or class would be required. 

                                                                         Page 47
<PAGE>
 
       Shareholders of a Fund or class would not be entitled to vote on any
       matter which does not affect that Fund or class but which would require a
       separate vote of another Fund or class.

       When issued, shares of a Fund are fully paid and nonassessable, and have
       no preemptive or subscription rights.  There are no conversion rights.
       Shares do not have cumulative voting rights, which means that in
       situations in which shareholders elect trustees, holders of more than 50%
       of the shares voting for the election of trustees can elect 100% of the
       trustees of such Trust and the holders of less than 50% of the shares
       voting for the election of trustees will not be able to elect any
       trustees.

       Each Master Trust Agreement provides that the trustees of the Trust
       shall hold office during the existence of the Trust, except as follows:
       (a) any trustee may resign or retire; or (b) any trustee may be removed
       by a vote of shareholders holding not less than two-thirds of the
       outstanding shares of the Trust, or at any time by written instrument
       signed by at least two-thirds of the trustees and specifying when such
       removal becomes effective.  The Trustees are required to call a meeting
       for the purpose of considering the removal of a person serving as Trustee
       if requested in writing to do so by the holders of not less than 10% of
       the outstanding shares of the Trust.

       A majority of the trustees is not affiliated with CIGNA Corporation or
       any of its subsidiary companies. The trustees meet quarterly to review
       the results of the Funds, to monitor investment activities and practices,
       and to review and act upon future plans for the Funds. The role of the
       trustees is not to approve specific investment purchases and sales, but
       rather to exercise a control and review function.


       APPENDIX
       -----------------------------------------------------------------
       Description of Money Market Instruments

       U.S. GOVERNMENT DIRECT OBLIGATIONS - Bills, notes, and bonds issued by
       the U.S. Treasury.

       U.S. GOVERNMENT AGENCIES SECURITIES - Certain Federal agencies such as
       the Government National Mortgage Association have been established as
       instrumentalities of the U.S. Government to supervise and finance certain
       types of activities.  Issues of these agencies, while not direct
       obligations of the U.S. Government, are either backed by the full faith
       and credit of the United States or are guaranteed by the Treasury or
       supported by the issuing agencies' right to borrow from the Treasury.

                                                                         Page 48
<PAGE>
 
       BANKERS' ACCEPTANCES - A bill of exchange or time draft drawn on and
       accepted by a commercial bank.  It is used by corporations to finance the
       shipment and storage of goods and to furnish dollar exchange.  Maturities
       are generally six months or less.

       CERTIFICATES OF DEPOSIT - A negotiable interest-bearing instrument with a
       specific maturity.  Certificates of deposit are issued by banks and
       savings and loan institutions in exchange for the deposit of funds and
       normally can be traded in the secondary market, prior to maturity.

       TIME DEPOSITS - A non-negotiable receipt issued by a bank in exchange for
       the deposit of funds.  Like a certificate of deposit, it earns a
       specified rate of interest over a definite period of time; however, it
       cannot be traded in the secondary market.

       COMMERCIAL PAPER - The term used to designate unsecured short-term
       promissory notes issued by corporations and other entities.  Maturities
       on these issues vary from a few days to nine months.
    
       COMMERCIAL LOAN PARTICIPATIONS - Participating interests in loans made by
       a bank, or a syndicate of banks represented by an agent bank, to
       corporate borrowers.  Loan participations may extend for the entire term
       of the loan or may extend only for short "strips" that correspond to
       stated payments on the underlying loan.  The loans underlying such
       participations may be secured or unsecured, and a Fund may invest in
       loans collateralized by mortgages on real property.  Each Fund will limit
       its investments in commercial loan participations to those which are
       considered by the Trustees (with the advice of CIGNA Investments) to be
       of comparable quality to permitted commercial paper investments.     

       REPURCHASE AGREEMENTS - A repurchase agreement is a contractual
       undertaking whereby the seller of securities (limited to U.S. Government
       securities, including securities issued or guaranteed by the U.S.
       Treasury or the various agencies and instrumentalities of the U.S.
       Government) agrees to repurchase the securities at a specified price on a
       future date determined by negotiations.  The repurchase agreement may be
       considered a loan by a Fund to the issuer of the agreement, a bank or
       securities dealer, with the U.S. Government security serving as
       collateral for the loan.

       VARIABLE AND FLOATING RATE INSTRUMENTS - Certain instruments issued,
       guaranteed or sponsored by the U.S. Government or its agencies, state and
       local government issuers, and certain debt instruments issued by domestic
       banks or corporations, may carry variable or floating rates of interest.
       Such instruments bear interest at rates which are not fixed, but which
       vary with 

                                                                         Page 49
<PAGE>
 
       changes in specified market rates or indices, such as a Federal Reserve
       composite index.

       Descriptions of Rating Categories

       The following are descriptions of ratings assigned by Moody's and S&P to
       certain debt securities in which the High Yield Fund and, to a lesser
       extent, the Income Fund may invest.  See the Statement of Additional
       Information for descriptions of other Moody's and S&P rating categories.

       Moody's:
       ------- 

       Ba - Bonds which are rated Ba are judged to have speculative elements;
       their future cannot be considered as well assured.  Often the protection
       of interest and principal payments may be very moderate and thereby not
       well safeguarded during other good and bad times over the future.
       Uncertainty of position characterizes bonds in this class.

       B - Bonds which are rated B generally lack characteristics of the
       desirable investment. Assurance of interest and principal payments or of
       maintenance of other terms of the contract over any long period of time
       may be small.

       Caa - Bonds which are rated Caa are of poor standing.  Such issues may be
       in default or there may be present elements of danger with respect to
       principal or interest.

       Ca - Bonds which are rated Ca represent obligations which are speculative
       in a high degree.  Such issues are often in default or have other marked
       shortcomings.

       C - Bonds which are rated C are the lowest rated class of bonds and
       issues so rated can be regarded as having extremely poor prospects of
       ever attaining any real investment standing.

       S&P:
       --- 

       BB, B, CCC, CC, C - Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is
       regarded, on balance, as predominantly speculative with respect to
       capacity to pay interest and repay principal in accordance with the terms
       of the obligations. 'BB' indicates the lowest degree of speculation and
       'C' the highest degree of speculation. While such debt will likely have
       some quality and protective characteristics, these are outweighed by
       large uncertainties of major risk exposures to adverse conditions.

                                                                         Page 50

GENERAL INFORMATION ABOUT THE TRUSTS
- ------------------------------------

The Trusts are Massachusetts business trusts.  CIFG was organized pursuant to a
Master Trust Agreement dated as of August 10, 1992, as amended from time to
time.  CFG was organized pursuant to a Master Trust Agreement dated April 10,
1985, as amended and restated by the First Amended and Restated Master Trust
Agreement dated as of March 1, 1996.  CIFG currently offers one series of shares
(CIGNA International Stock Fund).  CFG currently has seven series of shares
(CIGNA Money Market Fund, CIGNA Treasury Obligations Cash Fund, CIGNA Government
Obligations Cash Fund, CIGNA Government Securities Fund, CIGNA Income Fund,
CIGNA High Yield Fund and CIGNA S&P 500 Index Fund).  Each series is sometimes
referred to in this Statement of Additional Information as a "Fund".  CIGNA
Funds Group was formerly known as CIGNA Annuity Funds Group.  CIGNA Money Market
Fund and CIGNA Income Fund, two series of CFG, were formerly known as CIGNA
Annuity Money Market Fund and CIGNA Annuity Income Fund, respectively.  Five
additional series were added to CFG under the Amended and Restated Master Trust
Agreement.  The Board of Trustees of CFG and CIFG is authorized to create new
series of shares without the necessity of a vote of shareholders of the Trust.

The assets received by the Trust from the issue or sale of shares of each of 
its series of shares, and all income, earnings, profits and proceeds thereof,
subject only to the rights of creditors, are specifically allocated to the
appropriate series.  They constitute the underlying assets of each series, are
required to be segregated on the books of account, and are to be charged with
the expenses with respect to such series.  Any general expenses of the Trust not
readily identifiable as belonging to a particular series shall be allocated by
or under the direction of the Board of Trustees, primarily on the basis of
relative net assets.

Each share of each series represents an equal proportionate interest in that
series with each other share and is entitled to such dividends and distributions
out of the income belonging to such series as are declared by the Board.  Upon
any liquidation of a Trust, shareholders of each series of the Trust are
entitled to share pro rata in the net assets belonging to that series available
for distribution.

INVESTMENT OBJECTIVES AND POLICIES
- ----------------------------------

The following information supplements the material contained in the prospectus
regarding each Fund's investment objectives and policies.

Description of Money Market Instruments
- ---------------------------------------

U.S. GOVERNMENT DIRECT OBLIGATIONS--issued by the U.S. Treasury and include
bills, notes, and bonds.


CIGNA Funds Group/CIGNA Institutional Funds Group                         Page 3
<PAGE>
 
   .  Treasury bills are issued with maturities of up to one year.  They are
      issued in bearer form, are sold on a discount basis and are payable at par
      value at maturity.

   .  Treasury notes are longer-term interest bearing obligations with original
      maturities of one to ten years.

   .  Treasury bonds are longer-term interest bearing obligations with original
      maturities from ten to thirty years.

U.S. GOVERNMENT AGENCIES SECURITIES--Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities.  These agencies include the Bank for Cooperatives,
Federal Land Banks, Federal Intermediate Credit Banks, Federal Home Loan Banks,
Federal National Mortgage Association, Government National Mortgage Association,
Export-Import Bank, and Tennessee Valley Authority.  Issues of these agencies,
while not direct obligations of the U.S. Government, are either backed by the
full faith and credit of the United States or are guaranteed by the Treasury or
supported by the issuing agencies' right to borrow from the Treasury.  There can
be no assurance that the U.S. Government itself will pay interest and principal
on securities as to which it is not legally obligated to do so.

BANKERS' ACCEPTANCES--A banker's acceptance is a bill of exchange or time draft
drawn on and accepted by a commercial bank.  It is used by corporations to
finance the shipment and storage of goods and to furnish dollar exchange.  When
the draft is accepted by a bank, the bank guarantees to pay the face value of
the instrument on its maturity date.  An investor can purchase a banker's
acceptance in the secondary market at the going rate of discount for a specific
maturity.  In addition to purchasing bankers' acceptances from domestic branches
and foreign branches of U.S. commercial banks, bankers' acceptances denominated
in each case in U.S. dollars, may be purchased from foreign branches and U.S.
branches of foreign banks having at least one billion dollars (U.S.) of assets.
Maturities are generally six months or less.

CERTIFICATES OF DEPOSIT--A certificate of deposit ("CD") is a negotiable
interest-bearing instrument with a specific maturity.  Certificates of deposit
are issued by banks and savings and loan institutions in exchange for the
deposit of funds and normally can be traded in the secondary market, prior to
maturity.  Each Fund may invest in U.S. dollar denominated CD's issued by
domestic branches and foreign branches of U.S. banks which are members of the
Federal Reserve System; by foreign branches and U.S. branches of foreign banks
and by U.S. domiciled savings and loan institutions having in each case at least
one billion dollars (U.S.) of assets.  CD's issued by foreign branches of U.S.
banks are called "Eurodollar CD's" while CD's issued by U.S. branches of foreign
banks are called "Yankee CD's."


CIGNA Funds Group/CIGNA Institutional Funds Group                         Page 4
<PAGE>
 
COMMERCIAL LOAN PARTICIPATIONS--Each Fund will limit its investments in loan
participations to those which are considered by the Fund's adviser, CIGNA
Investments, Inc. ("CII"), or the Fund's sub-adviser to be of comparable quality
to permitted commercial paper investments. These ratings are described under
"Ratings of Securities." Further, for the purposes of each Fund's investment
restrictions, each loan participation will be treated as an obligation of both
the originating bank (or agent bank in the case of loans originated by a
syndicate of banks) and the corporate borrower. In addition, each Fund may only
invest up to 5% of the value of its total assets in loan participations.

Loan participations in which a Fund may invest may vary in legal structure.
Occasionally, lenders assign to another institution both the lenders's rights
and obligations under a credit agreement.  Since this type of assignment
relieves the original lender of its obligations, it is called a novation.  Such
novations are relatively rare since they typically require the consent of the
borrower.  More typically, a lender assigns only its right to receive payments
of principal and interest under a promissory note, credit agreement or similar
document.  A true assignment shifts to the assignee the direct debtor-creditor
relationship with the underlying borrower.  Alternatively, a lender may assign
only part of its rights to receive payments pursuant to the underlying
instrument or loan agreement.  Such partial assignments, which are more
accurately characterized as "participating interests,"  do not shift the debtor-
creditor relationship to the assignee, who must rely on the original lending
institution to collect sums due and to otherwise enforce its rights against the
agent bank which administers the loan or against the underlying borrower.  An
active secondary market for particular loan participations may not develop,
which would result in a substantial restriction on a Fund's ability to liquidate
such participations prior to maturity.

REPURCHASE AGREEMENTS--Each Fund may engage in repurchase agreement
transactions in pursuit of its investment objective.  Under the terms of a
typical repurchase agreement, a Fund purchases an underlying U.S. Government
security, including securities issued or guaranteed by the U.S. Treasury or
agencies and instrumentalities of the U.S. Government, for a relatively short
period (most likely overnight and usually not more than five days) subject to an
obligation of the seller to repurchase, and the Fund to resell, the security at
an agreed upon price and time, thereby determining the yield during the Fund's
holding period.  The arrangement results in a fixed rate of return that is not
subject to market fluctuations during the Fund's holding period.  The Funds may
enter into repurchase agreements with banks having $1 billion or more of assets
and with broker/dealers having net capital of $100 million or more.  The Funds
require that the counter-party's obligation under repurchase agreements be
sufficiently collateralized so that the value of the underlying collateral
securities at least equals the amount of the repurchase agreement.  Also, the
Funds require that the underlying securities be 


CIGNA Funds Group/CIGNA Institutional Funds Group                         Page 5
<PAGE>
 
held by the custodian of Fund assets, either physically or under the Federal
Book Entry System.

Repurchase agreements could involve certain risks in the event of default or
insolvency of the repurchasing bank or broker/dealer, including possible delays
or restrictions upon a Fund's ability to dispose of the underlying securities.
CII, in accordance with procedures adopted by the Board of Trustees of the
Trust, monitors and evaluates the credit-worthiness of banks and dealers with
which the Funds engage in repurchase agreements.

TIME DEPOSITS--A time deposit is a non-negotiable receipt issued by a bank in
exchange for the deposit of funds.  Like a certificate of deposit, it earns a
specified rate of interest over a definite period of time; however, it cannot be
traded in the secondary market.  U.S. dollar denominated time deposits may be
purchased from domestic branches and foreign branches of U.S. banks which are
members of the Federal Reserve System (not including savings and loan
institutions) and from foreign branches and U.S. branches of foreign banks
having at least one billion dollars (U.S.) of assets.

U.S. dollar denominated certificates of deposit, time deposits and bankers'
acceptances issued by foreign branches of U.S. banks or by foreign banks either
in the U.S. or abroad may present investment risks in addition to the risks
involved in investments in obligations of, or guaranteed by, domestic banks.
Such risks include future political and economic developments, the possible
imposition of withholding taxes on interest income payable on such obligations,
the possible seizure or nationalization of foreign deposits, the possible
establishment of exchange controls or the adoption of other governmental
restrictions.  Generally, foreign branches of U.S. banks and U.S. branches of
foreign banks are subject to fewer U.S. regulatory restrictions than are
applicable to domestic banks, and foreign branches of U.S. banks may be subject
to less stringent reserve requirements than domestic banks.  U.S. branches of
foreign banks and foreign branches of U.S. banks may provide less public
information than, and may not be subject to the same accounting, auditing and
financial record-keeping standards as, domestic banks.  Foreign branches of
foreign banks generally would not be subject to any U.S. regulatory restrictions
or disclosure, financial recordkeeping or accounting requirements.

COMMERCIAL PAPER--Commercial paper is the term used to designate unsecured
short-term promissory notes issued by corporations and other business entities.
Maturities on these issues vary from a few days to nine months.  Commercial
paper may be purchased from U.S. domiciled issuers.  Commercial paper may also
be purchased from foreign issuers issued either in the U.S. ("Yankee" commercial
paper) or abroad if, in any case, such paper is denominated in U.S. dollars.

OTHER CORPORATE OBLIGATIONS--Each Fund may purchase notes, bonds and debentures
issued by corporations and other business entities.  However, the Money Market
Funds will purchase such obligations only 


CIGNA Funds Group/CIGNA Institutional Funds Group                         Page 6
<PAGE>
 
if at the time of purchase there are 397 days or less remaining until maturity
or if they carry a variable or floating rate of interest.

VARIABLE AND FLOATING RATE INSTRUMENTS--Certain instruments issued, guaranteed
or sponsored by the U.S. Government or its agencies, or state and local
government issuers, and certain debt instruments issued by domestic banks or
corporations, may carry variable or floating rates of interest.  Such
instruments bear interest at rates which are not fixed, but which vary with
changes in specified market rates or indices, such as a Federal Reserve
composite index.

Description of Income Instruments for the High Yield Fund
- ---------------------------------------------------------

As noted in the prospectus, the Fund purchases principally debt securities that
are rated Ba or lower by Moody's or BB or lower by S&P.

Included among the high-yield, high risk securities in which the Fund may
invest are securities issued in connection with corporate restructurings such as
takeovers or leveraged buyouts.  Securities issued to finance corporate
restructurings may have special credit risks due to the highly leveraged
conditions of the issuer.  In addition, such issuers may lose experienced
management as a result of the restructuring.  Also, the market price of such
securities may be more volatile to the extent that expected benefits from the
restructuring do not materialize.

Because investors generally perceive that there are greater risks associated
with the medium to lower rated securities of the type constituting high-yield,
high risk securities, the yields and prices of such securities may tend to
fluctuate more than those for higher rated securities.  In the lower quality
segments of the fixed income securities market, changes in perceptions of
issuer's creditworthiness tend to occur more frequently and in a more pronounced
manner than do such changes with respect to higher quality segments of the fixed
income securities market, causing greater yield and price volatility.
Commissions and underwriting spreads associated with the purchase of high-yield,
high risk bonds are typically higher than those associated with the purchase of
high grade bonds.

The Fund may also invest in preferred stocks with yields that are attractive,
provided that such investments are otherwise consistent with the investment
objective and policies of the Fund.  A preferred stock is an equity security
that entitles the holders to a priority in liquidation over holders of the
issuer's common stock.  In liquidation, the holders of preferred stock are
subordinate to the holders of the issuer's debt obligations.  Typically,
preferred stocks include the right to receive regular dividend payments and may
also include conversion rights, put and call obligations and other features.  In
determining whether to invest in any particular stock, CII will consider all
relevant factors, including the dividend yield, its conversion features, if any,
its liquidity, and the overall 


CIGNA Funds Group/CIGNA Institutional Funds Group                         Page 7
<PAGE>
 
financial condition of the issuer. Under normal circumstances, the Fund will not
invest more than 10% of its assets in preferred stock.

The Fund may invest up to 15% of its total assets in "private placements,"
i.e., securities that are subject to restrictions on resale because they have
not been registered under the securities Act of 1933, as amended (the "1933
Act").  Privately placed securities, which include securities eligible for
resale under Rule 144A under the 1933 Act, ordinarily can be sold by the Fund in
privately negotiated transactions to a limited number and/or particular type of
purchasers or in a public offering made pursuant to an effective registration
statement under the 1933 act.  Private or public sales of such securities by the
Fund are likely to involve delays and expenses.  Private sales require
negotiation with one or more purchasers and may produce less favorable prices
than the sale of similar unrestricted securities.  Public sales generally
involve the time and expense of the preparation and processing of a registration
statement under the 1933 Act (and the possible decline in value of the
securities during such period) and may involve the payment of underwriting
commissions.  For these reasons, restricted securities are less liquid than
registered securities and certain restricted securities may be illiquid.  The
lack of third party evaluation of the credit quality of these securities and the
possibility of a less liquid secondary market because of restrictions placed by
some investors with respect to the purchase of non-rated securities may also
increase the risk to investors.

The Fund will not acquire common stocks, except when (i) attached to or
included in a unit with income-generating securities that otherwise would be
attractive to the Fund; (ii) acquired through the exercise of equity features
accompanying convertible securities held by the Fund, such as conversion or
exchange privileges or warrants for the acquisition of stock or equity interest
of the same or different issuer; or (iii) in the case of an exchange offering
whereby the equity security would be acquired with the intention of exchanging
it for a debt security issued on a "when-issued" basis.

Description of Income Instruments for the Income Fund
- -----------------------------------------------------

In pursuing its investment objective, the Income Fund will principally invest
in the following types of interest-bearing securities:

   (1) Marketable debt securities that are rated at the time of purchase within
       the four highest grades assigned by Moody's Investors Service, Inc. (Aaa,
       Aa, A or Baa) or Standard & Poor's Corporation (AAA, AA, A or BBB); see
       "Ratings of Securities."

   (2) U.S. Government securities, as described below.

   (3) Obligations of, or guaranteed by, U.S. banks or bank holding companies,
       which obligations are considered by CII to have 



CIGNA Funds Group/CIGNA Institutional Funds Group                         Page 8
<PAGE>
 
       investment qualities comparable to securities which may be purchased
       under Item (1) above, although there can be no assurance that said
       obligations shall have such qualities.

   (4) Money market instruments eligible for purchase by the Money Market Fund,
       which instruments are considered by CII to have investment qualities
       comparable to securities which may be purchased under Item (1) above,
       although there can be no assurance that said obligations shall have such
       qualities.

   (5) Marketable securities (payable in U.S. dollars) of, or guaranteed by, the
       Government of Canada or of a Province of Canada or any instrumentality or
       political subdivision thereof.

The balance of the Income Fund's assets may be invested in other fixed-income
securities, including straight debt and convertible debt securities and
preferred stock.  Investment positions may be held in common stock and similar
equity securities (including warrants or rights to purchase equity investments
as described below) when they are acquired as parts of units with fixed-income
securities or upon exercise of such warrants or rights or upon the conversion of
such securities.  The Income Fund also may purchase and sell interest rate
futures contracts and purchase options on futures contracts as described under
"Futures Contracts" and "Options on Futures Contracts."

U.S. Government securities include a variety of securities that are issued or
guaranteed by the U.S. Treasury, by various agencies of the U.S. Treasury, by
various agencies of the U.S. Government or by various instrumentalities that
have been established or sponsored by the U.S. Government.  Treasury securities
include Treasury bills, Treasury notes and Treasury bonds.  Treasury bills have
a maturity of one year or less; Treasury notes have maturities of one to ten
years; Treasury bonds generally have a maturity of greater than ten years.  The
Federal agencies established as instrumentalities of the U.S. Government to
supervise and finance certain types of activities include the Federal Home Loan
Banks, the Government National Mortgage Association, the Federal National
Mortgage Association, the Federal Land Banks, the Small Business Administration,
the Export-Import Bank, the Federal Intermediate Credit Banks and the Bank for
Cooperatives.

U.S. Government securities may take the form of participation interests in, and
may be evidenced by, deposit or safekeeping receipts.  Participation interests
are pro rata interests in U.S. Government securities such as interests in pools
of mortgages sold by the Government National Mortgage Association; instruments
evidencing deposit or safekeeping are documentary receipts for such original
securities held in custody by others.  The Fund will not invest in obligations
of the Asian Development Bank, the Inter-American Development Bank or the
International Bank for Reconstruction and Development (World Bank).



CIGNA Funds Group/CIGNA Institutional Funds Group                         Page 9
<PAGE>
 
U.S. Government obligations, including those that are guaranteed by Federal
agencies or instrumentalities, may or may not be backed by the "full faith and
credit" of the United States. Some securities issued by Federal agencies or
instrumentalities are only supported by the credit of the agency or
instrumentality (such as the Federal Home Loan Banks) while others have an
additional line of credit with the U.S. Treasury (such as the Federal National
Mortgage Association). Certain securities issued by Federal agencies or
instrumentalities backed by the full faith and credit of the U.S. Government
include those issued by the Government National Mortgage Association and the
Small Business Administration. In the case of securities not backed by the full
faith and credit of the United States, the Fund must look principally to the
agency issuing or guaranteeing the obligation for ultimate repayment and may not
be able to assert a claim against the United States itself in the event the
agency or instrumentality does not meet its commitments.

Warrants are, in effect, longer term call options.  They give the holder the
right to purchase a given number of shares of a particular company at specified
prices within certain periods of time.  The purchaser of a warrant expects that
the market price of the security will exceed the purchase price of the warrant
plus its exercise price, thus resulting in a profit.  However, since the market
price may never exceed the exercise price before the expiration date of the
warrant, the purchaser of the warrant risks the loss of the entire purchase
price of the warrant.

Warrants generally trade in the open market and may be sold rather than
exercised.  Warrants are sometimes sold in unit form with other securities of an
issuer.  Units of warrants and common stock may be employed in financing
unseasoned companies.  The purchase price varies with the security, the life of
the warrant and various other investment factors.  Investments in warrants,
valued at the lower of cost or market, may not exceed 5% of the value of the
Fund's net assets.

Considerations of liquidity and preservation of capital mean that the Income
Fund may not necessarily invest in instruments paying the highest available
yield at a particular time.  This Fund may, consistent with its investment
objective, attempt to maximize yields by buying and selling portfolio
investments in anticipation of or in response to changing economic and money
market conditions and trends.  This Fund will also invest to take advantage of
what are believed to be temporary disparities in the yields of the different
segments of the market or among particular instruments within the same segment
of the market.  These policies, as well as the relatively short maturity of
obligations to be held by this Fund, may result in frequent changes in portfolio
holdings.  There usually are no brokerage commissions as such paid in connection
with the purchase of securities of the type in which this Fund may invest.  See
"Brokerage Allocation" for a discussion of underwriters' commissions and
dealers' spreads involved in the purchase and sale of portfolio securities.



CIGNA Funds Group/CIGNA Institutional Funds Group                        Page 10
<PAGE>
 
Changes in interest rates are likely to result in increases or decreases in the
value of the investments of the Income Fund. The value of the securities in this
Fund can be expected to vary inversely with the changes in prevailing interest
rates. Thus, depending upon whether interest rates have increased or decreased
since the time a security was purchased, such security, if sold, might be sold
at a loss or a gain. If debt instruments are held to maturity, no gain or loss
would normally be realized as a result of interest rate fluctuations.

High Yield Fund and Income Fund:  Risk Factors
- ----------------------------------------------

As noted in the prospectus, the High Yield Fund, and, to a lesser extent, the
Income Fund invest in debt securities of less than investment grade (i.e.,
securities rated Ba/BB or below by Moody's and S&P).  Such securities are often
referred to as high yield or junk bonds and are typically considered "high risk"
securities.  High yield bonds may be subject to certain risk factors to which
other securities are not subject to the same degree.  An economic downturn tends
to disrupt the market for high yield bonds and adversely effect their values.
Such an economic downturn may be expected to result in increased price
volatility of high yield bonds and of the value of the Fund's shares, and an
increase in issuers' defaults on such bonds.

Also, issuers of high yield bonds are substantially leveraged, which may impair
their ability to meet their obligations.  In some cases, the securities in which
the Fund invests are subordinated to the prior payment of senior indebtedness,
thus potentially limiting the Fund's ability to recover full principal or to
receive payments when senior securities are in default.  When the secondary
market for high yield bonds becomes increasingly illiquid, or in the absence of
readily available market quotations for high yield bonds, the relative lack of
reliable, objective data makes the responsibility of the Trustees to value the
Fund's securities more difficult, and judgement plays a greater role in the
valuation of portfolio securities.  Also, increased illiquidity of the high
yield bond market may affect the Fund's ability to dispose of portfolio
securities at a desirable price.

The credit rating of a security does not necessarily address its market value
risk.  Also, ratings may from time to time, be changed to reflect developments
in the issuer's financial condition.  High yield bonds have speculative
characteristics which are apt to increase in number and significance with each
lower rating category.  Also, prices of high yield bonds have been found to be
less sensitive to interest rate changes and more sensitive to adverse economic
changes and individual corporate developments than more highly rated
investments.

Certain laws or regulations may have a material effect on the Fund's net asset
value and investment practices.  For example, legislation requiring federally-
insured savings and loan associations to divest their investments in high yield
bonds may further adversely affect the market for such bonds.

<PAGE>
 
Characteristics of the S&P 500 Index Fund
- -----------------------------------------

The S&P 500 Index Fund seeks long-term growth of capital by investing primarily
in common stocks. Realization of current income is an incidental consideration,
although it is hoped that growth in income will accompany growth in capital. The
portfolio of the Fund normally will consist primarily of equity securities of
companies which compose the S&P 500.

The Fund also may invest in certain short-term fixed income securities, stock
index futures and options on futures, as more fully described in the prospectus
under "S&P 500 Index Fund" and "Stock Index Futures Contracts and Related
Options."

Characteristics of the International Stock Fund
- -----------------------------------------------

The Fund will invest in securities listed on foreign securities exchanges or
securities traded in the over-the-counter market.  Debt securities will be
acquired in new offerings or in principal trades with broker/dealers.
Ordinarily, the Fund will not purchase securities with the intention of engaging
in short-term trading.  However, any particular security will be sold, and the
proceeds reinvested, whenever such action is deemed prudent from the viewpoint
of the Fund's investment objective, regardless of the holding period of that
security.  The rating applied to a debt security or money market instrument (see
"Ratings of Securities" below) at the time the security is purchased by the Fund
may be changed while the Fund holds such security in its portfolio.  This change
may affect, but may not compel, a decision to dispose of a security.
Nonetheless, the Fund does not intend to hold more than 5% of its net assets in
bonds rated below investment grade (i.e. bonds rated BB or Ba or below by S&P or
Moody's or if not so rated, which in the opinion of CIGNA International
Investment Advisors, Ltd. ("CIIA"), sub-adviser to the Fund, are of comparable
quality).  Therefore, the Fund will dispose of any bond, as soon as practicable
consistent with achieving an orderly disposition, that would cause the Fund to
violate the above-referenced limitation.  If the major rating services used by
the Fund were to alter their standards or systems for rating, the Fund would
then employ ratings under the revised standards or systems that would be
comparable to those specified in its current investment objective, policies and
restrictions.

Characteristics of the Money Market Funds
- -----------------------------------------

The types of money market instruments in which the Funds presently invest (to
the extent permitted by each Fund's investment objective) are listed under
"Description of Money Market Instruments" in the appendix of the prospectus and
in this Statement of Additional Information.  If the Trustees determine that it
may be advantageous to invest in other types of money market instruments, a
Money Market Fund may invest in such instruments, if it is permitted to do so by
its investment objective, policies and restrictions.




CIGNA Funds Group/CIGNA Institutional Funds Group                        Page 12
<PAGE>
 
As discussed in the Prospectus, the Money Market Fund may invest in U.S. dollar-
denominated obligations of U.S. and foreign depository institutions, including
commercial and savings banks and savings and loan associations.  The obligations
may be issued by U.S. or foreign depository institutions, foreign branches or
subsidiaries of U.S. depository institutions ("Eurodollar" obligations), U.S.
branches or subsidiaries of foreign depository institutions ("Yankeedollar"
obligations) or foreign branches or subsidiaries of foreign depository
institutions.  Obligations of foreign depository institutions, their branches
and subsidiaries, and Eurodollar and Yankeedollar obligations may involve
additional investment risks to the risks of obligations of U.S. institutions.
Such investment risk include adverse political and economic developments, the
possible imposition of withholding taxes on interest income payable on such
obligations, the possible seizure or nationalization of foreign deposits and the
possible establishment of exchange controls or other foreign governmental laws
or restrictions which might adversely affect the payment of principal and
interest.  Generally, the issuers of such obligations are subject to fewer
regulatory requirements than are applicable to U.S. banks.  Foreign depository
institutions, their branches or subsidiaries, and foreign branches or
subsidiaries of U.S. banks may be subject to less stringent reserve requirements
than U.S. banks.  U.S. branches or subsidiaries of foreign banks are subject to
the reserve requirements of the state in which they are located.  There may be
less publicly available information about a foreign bank or a branch or
subsidiary of a foreign bank than about a U.S. institution, and such branches or
subsidiaries may not be subject to the same accounting, auditing and financial
record keeping standards and requirements as U.S. banks.  Evidence of ownership
of foreign depository and Eurodollar obligations may be held outside of the
United States and the Fund may be subject to the risks associated with the
holding of such property overseas.  Foreign depository and Eurodollar
obligations of the Fund held overseas will be held by foreign branches of the
custodian for the Funds portfolio securities or by other U.S. or foreign banks
under subcustodian arrangements complying with the requirements of the
Investment Company Act of 1940, as amended (the "1940 Act").  CII will consider
the above factors in making investments in foreign depository, Eurodollar and
Yankeedollar obligations and will not knowingly purchase obligations which, at
the time of purchase, are subject to exchange controls or withholding taxes.
Generally, the Fund will limit its foreign depository and Yankeedollar
investments to obligations of banks organized in Canada, France, Germany, Japan,
the Netherlands, Switzerland, the United Kingdom and other western
industrialized nations.  As discussed in the prospectus, the Fund may also
invest in U.S. dollar-denominated commercial paper and other short-term
obligations issued by foreign entities.  Such investments are subject to quality
standards similar to those applicable to investments in comparable obligations
of domestic issuers.  Investments in foreign entities in general involve the
same risks as those described above in connection with investments in Eurodollar
and Yankeedollar obligations and obligations of foreign depository institutions
and their foreign branches and subsidiaries.

The Money Market Funds' investments in short-term corporate debt and bank money
instruments will be rated, or will be issued by issuers who have been rated, in
one of the two highest rating categories for short-term debt obligations by a
nationally recognized statistical rating organization (an "NRSRO") or, if not
rated, will be of comparable quality as determined by the Trustees of the Trust.
The Money Market Fund's investments in corporate bonds and debentures (which
must have maturities at the date of purchase of 397 days (13 months) or less)
will be in issuers who have received from an NRSRO a rating with respect to a
class of short-term debt obligations that is comparable in priority and security
with the investment in one of the two highest rating categories for short-term
obligations or if not rated, will be of comparable quality as determined by the
Trustees of the Trust. Currently, there are six NRSROs: Duff and Phelps Inc.,
Fitch Investors Services, Inc., IBCA Limited and its affiliate IBCA Inc.,
Thompson BankWatch, Inc., Moody's Investors Service Inc. and Standard & Poor's
Rating Group. See "Appendix--Description of Money Market Instruments".

The rating applied to a security at the time the security is purchased by a Fund
may be changed while the Fund holds such security in its portfolio.  This change
may affect, but will not necessarily compel, a decision to dispose of a
security.  If the major rating services used by the Fund were to alter their
standards or systems for rating, the Fund would then employ ratings under the
revised standards or systems that would be comparable to those specified in its
current investment objective, policies and restrictions.

The Board of Trustees has established procedures in compliance with Rule 2a-7
under the 1940 Act that include reviews of portfolio holdings by the Trustees at
such intervals as they may deem appropriate to determine whether net asset value
of the Money Market Funds, calculated by using available market quotations,
deviates from $1.00 per share and, if so, whether such deviation may result in
material dilution or is otherwise unfair to existing shareholders. In the event
the Trustees determine that a deviation having such a result exists, they intend
to take such corrective action as they deem necessary and appropriate, including
the sale of portfolio instruments prior to maturity in order to realize capital
gains or losses or to shorten average portfolio maturity; withholding dividends;
or establishing a net asset value per share by using available market
quotations; in which case, the net asset value could possibly be greater or less
than $1.00 per share. If the Trustees deem it inadvisable to continue the
practice of maintaining the net asset value at $1.00 per share, they may alter
this procedure. The shareholders of the Fund will be notified promptly after any
such change.

Any increase in the value of a shareholder's investment in a Money Market Fund
resulting from the reinvestment of dividend income is reflected by an increase
in the number of shares in the shareholder's account.

Matters relating to all Funds
- -----------------------------

Except as described under "Investment Restrictions," the foregoing investment
characteristics are not fundamental and the Board of Trustees may change such
policies without shareholder approval. The Board will not change a Fund's
investment objectives without the required shareholder vote as set forth in
"Investment Restrictions" below. There is risk inherent in any investment, and
there is no assurance that any of the strategies and methods of investment
available to any Fund will result in the achievement of its objectives.

Each Fund's investments must be consistent with its investment objective and
policies.  Accordingly, not all of the security types and investment techniques
discussed below are eligible investments for each of the Funds.

FUTURES CONTRACTS
- -----------------

A stock index assigns relative values to the common stocks included in the index
and the index fluctuates with changes in the market values of the common stocks
so included.  A stock index futures contract is a bilateral agreement pursuant
to which two parties agree to take or make delivery of an amount of cash equal
to a specified dollar amount times the difference between the stock index value
at the close of the last trading day of the contract and the price at which the
futures contract is originally struck.  No physical delivery of the underlying
stocks in the index is made.

Generally, a Fund will only enter into stock index futures contracts as a hedge
against changes resulting from market conditions in the values of the securities
held or which the Fund intends to purchase.  When the Fund anticipates a
significant market or market sector advance, the purchase of a stock index
futures contract affords a hedge against not participating in such advance.
Conversely, in anticipation of or in a general market or market sector decline
that adversely affects the market values of the Fund's portfolio of securities,
the Fund may sell stock index futures contracts.  The S&P 500 Index Fund's use
of stock index futures is discussed in the prospectus.

An interest rate futures contract is an agreement between two parties to buy and
sell a debt security for a set price on a future date.  A Fund generally may
enter into interest rate futures contracts for the purpose of hedging debt
securities in their portfolios or the value of debt securities which the Funds
intend to purchase.  For example, if one of these Funds owned long-term debt
securities and interest rates were expected to increase, they might sell
interest rate futures contracts.  If, on the other hand, these Funds held cash
reserves and interest rates were expected to decline, they might purchase
interest rate futures contracts.

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 15
<PAGE>
 
In cases of purchases of futures contracts, an amount of cash and cash
equivalents, equal to the market value of the futures contracts (less any
related margin deposits), will be deposited in a segregated account with the
Fund's custodian to collateralize the position and ensure that the use of such
futures contracts is unleveraged. Unlike when a Fund purchases or sells a
security, no price is paid or received by a Fund upon the purchase or sale of a
futures contract. Initially, a Fund will be required to deposit with the
custodian for the Fund for the account of the broker a stated amount, as called
for by a particular contract, of cash or U.S. Treasury bills. This amount is
known as "initial margin." The nature of initial margin in futures transactions
is different from that of margin in securities transactions in that futures
contract margin does not involve the borrowing of funds by the customer to
finance the transactions.

Rather, the initial margin is in the nature of a performance bond or good faith
deposit on the contract which is returned to the applicable Fund upon
termination of the futures contract assuming all contractual obligations have
been satisfied.  Subsequent payments, called "variation margin," to and from the
broker will be made on a daily basis as the price of the futures contract
fluctuates making the long and short positions in the futures contract more or
less valuable, a process known as "marking-to-market."  For example, when a Fund
has purchased a stock index futures contract and the price of the underlying
stock index has risen, that position will have increased in value and the Fund
will receive from the broker a variation margin payment with respect to that
increase in value.  Conversely, where a Fund purchases a stock index futures
contract and the price of the underlying stock index has declined, the position
would be less valuable and the Fund would be required to make a variation margin
payment to the broker.  Variation margin payments would be made in a similar
fashion when a Fund purchases an interest rate futures contract.  At any time
prior to expiration of the futures contract, a Fund may elect to close the
position by taking an opposite position which will operate to terminate the
Fund's position in the futures contract.  A final determination of variation
margin is then made, additional cash is required to be paid by or released to
the Fund and the Fund realizes a loss or a gain.

OPTIONS ON FUTURES CONTRACTS
- ----------------------------

An option on a futures contract gives the purchaser (the Fund) the right, in
return for the premium paid, to assume a position in a futures contract (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price at any time during the option exercise period.  The
writer of the option is required upon exercise to assume an offsetting futures
position (a short position if the option is a call and a long position if the
option is a put) at a specified exercise price at any time during the period of
the option.  Upon exercise of the option, the assumption of offsetting futures
positions by the writer and holder of the option will be accompanied by delivery
of the accumulated cash balance in the writer's futures margin account which
represents the amount by which 

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 16
<PAGE>
 
the market price of the futures contract, at exercise, exceeds, in the case of a
call, or is less than, in the case of a put, the exercise price of the option on
the futures contract. If an option on a futures contract is exercised on the
last trading date prior to the expiration date of the option, the settlement
will be made entirely in cash equal to the difference between the exercise price
of the option and the closing price of the futures contract on the expiration
date.

The S&P 500 Index Fund's use of options on futures contracts is discussed in the
prospectus. The other Funds may purchase put options on futures contracts to
hedge against the risk of falling prices for their portfolio securities, and may
purchase call options on futures contracts as a hedge against a rise in the
price of securities which they intend to purchase. Options on futures contracts
may also be used to hedge the risks of changes in the exchange rate of foreign
currencies. The purchase of a put option on a futures contract is similar to the
purchase of protective put options on portfolio securities or a foreign
currency. 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 or a foreign
currency. 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
securities or currency, it may or may not be less risky than ownership of the
futures contract or underlying securities or currency.

RISKS AS TO FUTURES CONTRACTS AND RELATED OPTIONS
- -------------------------------------------------

There are several risks in connection with the use of futures contracts and
related options as hedging devices.  One risk arises because of the imperfect
correlation between movements in the price of hedging instruments and movements
in the price of the stock, debt securities or foreign currency which are the
subject of the hedge.  If the price of a hedging instrument moves less than the
price of the stocks, debt securities or foreign currency which are the subject
of the hedge, the hedge will not be fully effective.  If the price of a hedging
instrument moves more than the price of the stock, debt securities or foreign
currency, a Fund will experience either a loss or a gain on the hedging
instrument which will not be completely offset by movements in the price of the
stock, debt securities or foreign currency which are the subject of the hedge.
The use of options on futures contracts involves the additional risk that
changes in the value of the underlying futures contract will not be fully
reflected in the value of the option.

Successful use of hedging instruments by a Fund is also subject to CII's ability
to predict correctly movements in the direction of the stock market, of interest
rates or of foreign exchange rates (foreign currencies).  Because of possible
price distortions in the futures and options markets and because of the
imperfect correlation between movements in the prices of hedging instruments and
the investments being hedged, even a correct forecast by CII of general market
trends may not result in a completely successful hedging transaction.

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 17
<PAGE>
 
It is also possible that where a Fund has sold futures contracts to hedge its
portfolio against a decline in the market, the market may advance and the value
of stocks or debt securities held in a Fund's portfolio may decline.  If this
occurred, a Fund would lose money on the futures contracts and also experience a
decline in the value of its portfolio securities.  Similar risks exist with
respect to foreign currency hedges.

Positions in futures contracts or options may be closed out only on an exchange
on which such contracts are traded. Although the Funds intend to purchase or
sell futures contracts or purchase options only on exchanges or boards of trade
where there appears to be an active market, there is no assurance that a liquid
market on an exchange or board of trade will exist for any particular contract
or at any particular time. If there is not a liquid market at a particular time,
it may not be possible to close a futures position or purchase an option at such
time. In the event of adverse price movements under those circumstances, a Fund
would continue to be required to make daily cash payments of maintenance margin
on its futures positions. The extent to which the Fund may engage in futures
contracts or related options will be limited by Internal Revenue Code
requirements for qualification as a regulated investment company and the Fund's
intent to continue to qualify as such. The result of a hedging program cannot be
foreseen and may cause the portfolio of the Fund to suffer losses which it would
not otherwise sustain.

FOREIGN CURRENCY TRANSACTIONS
- -----------------------------

Although they generally will not do so, the Funds may engage in currency
exchange transactions to protect against uncertainty in the level of future
currency exchange rates.

Generally, Funds may engage in both "transaction hedging" and "position
hedging".  When a Fund engages in transaction hedging, the Fund enters into
foreign currency transactions with respect to specific receivables or payables,
generally arising in connection with the purchase or sale of portfolio
securities.  A Fund will engage in transaction hedging when it desires to "lock
in" the U.S. dollar price of a security it has agreed to purchase or sell, or
the U.S. dollar equivalent of a dividend or interest payment in a foreign
currency.  By transaction hedging a Fund will attempt to protect itself against
a possible loss resulting from an adverse change in the relationship between the
U.S. dollar and the applicable foreign currency during the period between the
date on which the security is purchased or sold or on which the dividend or
interest payment is declared, and the date on which such payments are made or
received.

A Fund may purchase or sell a foreign currency on a spot (or cash) basis at the
prevailing spot rate in connection with the settlement of transactions in
portfolio securities denominated in that foreign currency.  A Fund may also
enter into contracts to purchase or sell foreign currencies at a future date
("forward contracts") and purchase and sell foreign currency futures contracts.

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 18
<PAGE>
 
For transaction hedging purposes a Fund may also purchase exchange-listed call
and put options on foreign currencies.  A put option on currency gives the Fund
the right to sell a currency at a specific exercise price.  A call option on
currency gives a Fund the right to purchase a currency at a specific exercise
price.  The time when call and put options are exercisable depends on whether
the options are American options or European options.  American options are
exercisable at anytime during the option period.  European options are
exercisable only on a designated date.

When it engages in position hedging, a Fund enters into foreign currency
exchange transactions to protect against a decline in the values of the foreign
currencies in which its portfolio securities are denominated or an increase in
the value of currency for securities which the Fund expects to purchase, when
the Fund holds cash or short-term investments. In connection with position
hedging, a Fund may purchase put or call options on foreign currency and foreign
currency futures contracts and buy or sell forward contracts and foreign
currency futures contracts. The Funds may also purchase or sell foreign currency
on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions
and the value of the portfolio securities involved will not generally be
possible since the future value of such securities in foreign currencies will
change as a consequence of market movements in the value of those securities
between the dates the currency exchange transactions are entered into and the
dates they mature.  For example, it may be necessary for a Fund to purchase
additional foreign currency on the spot market (and bear the expense of such
purchase) if the market value of the security or securities being hedged is less
than the amount of foreign currency a Fund is obligated to deliver and a
decision is made to sell the security or securities and make delivery of the
foreign currency.  Conversely, it may be necessary to sell on the spot market
some of the foreign currency received upon the sale of the portfolio security or
securities if the market value of such security or securities exceeds the amount
of foreign currency a Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying
prices of the securities which a Fund owns or intends to purchase or sell.  They
simply establish a rate of exchange which one can achieve at some future point
in time.  Additionally, although these techniques tend to minimize the risk of
loss due to a decline in the value of the hedged currency, they tend to limit
any potential gain which might result from the increase in value of such
currency.

Regardless of whether CII (or CIIA, as applicable) determines that it is
advisable to hedge a Fund's currency risk, the Funds will have to convert their
holdings of foreign currencies into U.S. dollars from time to time.  Although
foreign exchange dealers generally do not charge a fee for conversion, they do
realize a profit based on the difference (the "spread") between the prices at
which they are buying and selling various currencies.

Forward Currency Contracts
- --------------------------

A forward currency contract is an agreement between two parties to purchase and
sell a specific quantity of a currency at a price specified at the time of the
contract, with delivery and settlement at a specified future date.  In the case
of purchases of forward currency contracts, an amount of cash and cash
equivalents, equal to the market value of the portfolio security sold, will be
deposited in a segregated account with the Trust's Custodian to collateralize
the position and ensure that the use of such contracts is unleveraged.

In the case of a cancelable forward contract, the holder has the unilateral
right to cancel the contract at maturity by paying a specified fee. The
contracts are traded in the interbank market conducted directly between currency
traders (usually large commercial banks and their customers). A forward contract
generally has no deposit requirements, and no commissions are charged at any
stage for trades.

Forward currency contracts are less liquid than currency futures contracts, and
there is an increased risk of default by the counterparty as compared to futures
contracts.  Forward currency contracts differ from currency futures contracts in
certain other respects as well.  For example, the maturity date of a forward
contract may be any fixed number of days from the date in a given month.
Forward contracts may be in any amounts agreed upon by the parties rather than
predetermined amounts.  Also, forward currency contracts are traded directly
between currency traders so no intermediary is required.  A forward contract
generally requires no margin or other deposit.

At the maturity of a forward contract, the Fund may either accept or make
delivery of the currency specified in the contract, or at or prior to maturity
enter into a closing transaction involving the purchase or sale of an offsetting
contract.  Closing transactions with respect to forward contracts are usually
effected with the currency trader who is a party to the original forward
contract.  There is no assurance that the Fund will be able to close a forward
contract prior to maturity and, under such circumstances, the Fund may have
exposure to adverse changes in exchange rates.

Loans and Other Direct Debt Instruments.
- --------------------------------------- 

Direct debt instruments are interests in amounts owed by a corporate,
governmental, or other borrower to lenders or lending syndicates (loans and loan
participations), to suppliers of goods or services (trade claims or other
receivables), or to other parties.  Direct debt instruments are subject to each
Fund's policies regarding the quality of debt securities.

Purchaser of loans and other forms of direct indebtedness depend primarily upon
the creditworthiness of the borrower for payment of principal and interest.
Direct debt instruments may not be rated by 

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 20
<PAGE>
 
any NRSRO. If a Fund does not receive scheduled interest or principal payments
on such indebtedness, the Fund's share price and yield could be adversely
affected. Loans that are fully secured offer a Fund more protections than an
unsecured loan in the event of non-payment of scheduled interest or principal.
However, there is no assurance that the liquidation of collateral from a secured
loan would satisfy the borrower's obligation, or that the collateral could be
liquidated. Indebtedness of borrowers whose creditworthiness is poor involves
substantially greater risks and may be highly speculative. Borrowers that are in
bankruptcy or restructuring may never pay off their indebtedness, or may pay
only a small fraction of the amount owed. Direct indebtedness of developing
countries also involves a risk that the government entities responsible for the
repayment of the debt may be unable, or unwilling, to pay interest and repay
principal when due.

Investments in loans through direct assignment of a financial institution's
interests with respect to a loan may involve additional risks to a Fund.  For
example, if a loan is foreclosed, the Fund could become part owner of any
collateral, and would bear the costs and liabilities associates with owing and
disposing of the collateral.  In addition, it is conceivable that under emerging
legal theories of lender liability, the Fund could be held liable as a co-
lender.  Direct debt instruments may also involve a risk of insolvency of the
lending bank or other intermediary.  Direct debt instruments that are not in the
form of securities may offer less legal protection to a Fund in the event of
fraud or misrepresentation.  In the absence of definitive regulatory guidance,
each Fund relies on CII's (or CIIA's, as applicable) research in an attempt to
avoid situations where fraud or misrepresentation could adversely affect the
Fund.

A loan is often administered by a bank or other financial institution that acts
as agent for all holders.  The agent administers the terms of the loan, as
specified in the loan agreement.  Unless, under the terms of the loan or other
indebtedness, each Fund has direct recourse against the borrower, it may have to
rely on the agent to apply appropriate credit remedies against a borrower.  If
assets held by the agent for the benefit of a Fund were determined to be subject
to the claims of the agent's general creditors, the Fund might incur certain
costs and delays in realizing payment on the loan or loan participation and
could suffer a loss of principal or interest.

Each Fund (except the Money Market Fund, to a limited degree) limits the amount
of total assets that it will invest in any one issuer or in issues within the
same industry.  For purposes of these limitations, each Fund generally will
treat the borrower as the "issuer" of indebtedness held by the Fund.  In the
case of loan participations where a bank or other lending institution serves as
financial intermediary between each Fund and the borrower, if the participation
does not shift to the Fund the direct debtor-creditor relationship with the
borrower, SEC interpretations requires the Fund, in appropriate circumstances,
to treat both the lending bank or other lending institution and the borrower as
"issuers" for these purposes.  Treating a financial intermediary as an issuer of
indebtedness may 

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 21
<PAGE>
 
restrict a Fund's ability to invest in indebtedness related to a single
financial intermediary, or a group of intermediaries engaged in the same
industry, even if the underlying borrowers represent many different companies
and industries.

Restricted Securities generally can be sold in privately negotiated
- ---------------------                                              
transactions, pursuant to an exemption from registration under the Securities
Act of 1933, or in a registered public offering.  Where registration is
required, a Fund may be obligated to pay all or part of the registration expense
and a considerable period may elapse between the time it decides to seek
registration and the time it may be permitted to sell a security under an
effective registration statement.  If, during such a period, adverse market
conditions were to develop, a Fund might obtain a less favorable price than
prevailed when it decided to seek registration of the security.

Securities Lending.  A Fund may lend securities to parties such as broker-
- ------------------                                                       
dealers or institutional investors.

Securities lending allows a Fund to retain ownership of the securities loaned
and, at the same time, to earn additional income.  Since there may be delays in
the recovery of loaned securities, or even a loss of rights in collateral
supplied should the borrower fail financially, loans will be made only to
parties deemed by CII to be of good standing.  Furthermore, they will only be
made if, in CII's judgment, the consideration to be earned from such loans would
justify the risk.

CII understands that it is the current view of the SEC Staff that a fund may
engage in loan transactions only under the following conditions: (1) the fund
must receive 100% collateral in the form of cash or cash equivalents (e.g. U.S.
Treasury bills or notes) from the borrower; (2) the borrower must increase the
collateral whenever the market value of the securities loaned (determined on a
daily basis) rises above the value of the collateral; (3) after giving notice,
the fund must be able to terminate the loan at any time; (4) the fund must
receive reasonable interest on the loan or a flat fee from the borrower, as well
as amounts equivalent to any dividends, interest, or other distributions on the
securities loaned and to any increase in market value; (5) the fund may pay only
reasonable custodian fees in connection with the loan; and (6) the Board of
Trustees must be able to vote proxies on the securities loaned, either by
terminating the loan or by entering into an alternative arrangement with the
borrower.

Cash received through loan transactions may be invested in any security in which
a Fund is authorized to invest.  Investing this cash subjects that investment,
as well as the security loaned, to market forces (i.e., capital appreciation or
depreciation).

Securities of Small Capitalization Companies.  Smaller capitalization companies
- --------------------------------------------                                   
may have limited products lines, markets, or financial resources.  These
conditions may make them more susceptible to setbacks and reversals.  Therefore,
their securities may have limited 

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 22
<PAGE>
 
marketability and may be subject to more abrupt or erratic market movements than
securities of larger companies.

Sovereign Debt Obligations.  A Fund may purchase sovereign debt instruments
- --------------------------                                                 
issued or guaranteed by foreign governments or their agencies, including debt of
Latin American nations or other developing countries.  Sovereign debt may be in
the form of conventional securities or other types of debt instruments such as
loans or loan participations.  Sovereign debt of developing countries may
involve a high degree of risk, and may be in default or present the risk of
default.  Governmental entities responsible for repayment of the debt may be
unable or unwilling to repay principal and interest when due, and may require
renegotiation or rescheduling of debt payments.  In addition, prospects for
repayment of principal and interest may depend on political as well as economic
factors.

INVESTMENT RESTRICTIONS
- -----------------------

The Funds are subject to the following restrictions which may not be changed
without approval of the lesser of (i) 67% or more of that Fund's shares present
at a meeting if the holders of more than 50% of the outstanding shares are
present in person or represented by proxy, or (ii) more than 50% of that Fund's
outstanding shares.  Any investment restriction that involves a maximum or
minimum percentage of securities or assets shall not be considered to be
violated unless an excess over or a deficiency under the percentage occurs
immediately after, and is caused by, an acquisition or disposition of securities
or utilization of assets by the Fund.

A Fund may not:

1.  With respect to 75% of its assets, purchase the securities of any issuer if
    such purchase would cause more than 5% of the value of its total assets
    (taken at market value at the time of such investment) to be invested in the
    securities of such issuer except (a) U.S. Government securities including
    securities issued by its agencies and instrumentalities (or repurchase
    agreements with respect thereto), and (b) with respect to the Money Market
    Fund, to securities or obligations issued by U.S. banks.

2.  With respect to 75% of its assets, purchase the securities of any issuer if
    such purchase would cause more than 5% of the voting securities, or more
    than 10% of the securities of any class of such issuer (taken at the time of
    such investment), to be held by the Fund.

3.  Concentrate 25% or more of its total assets in a particular industry.
    Investing in cash or high quality money market instruments, for defensive
    purposes, securities issued or guaranteed by the U.S. Government, its
    agencies or instrumentalities or repurchase agreements secured by these
    instruments shall not be considered investments in a particular industry.
    In addition, each Money Market Fund may invest up to 

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 23
<PAGE>
 
    100% of its assets (a) in the domestic banking industry, (b) in the personal
    credit institution or business credit institution industries when, in the
    opinion of management, yield differentials make such investments desirable,
    or (c) in any combination of these.

4.  Purchase securities of any company with a record of less than three years'

    to be the making of loans, (b) enter into repurchase agreements, and (c)
    lend its portfolio securities in an amount not to exceed one-third of the
    value of its total assets, provided such loans are made in accordance with

TAX MATTERS
- -----------

All shareholders should consult a qualified tax adviser regarding their
investment in a Fund.

Each series of shares of the Trust is treated as a separate association taxable
as a corporation.

Each Fund intends to qualify and elect to be treated under the Internal Revenue
Code of 1986 (the Code), as amended, as a regulated investment company (RIC) for
each taxable year.  As of the date hereof, each Fund must, among other things
meet the following requirements:  A. Each Fund must generally derive at least
90% of its gross income from dividends, interest, payments with respect to
securities loans, gains from the sale or other disposition of stock, securities,
foreign currencies, or other income derived with respect to its business of
investing in such stock, securities or currencies.  

CIGNA Funds Group/CIGNA Institutional Funds Group                      Page 25
<PAGE>
 
B. Each Fund must derive less than 30% of its gross income from the sale or
disposition of any of the following held less than three months: i) stock or
securities, ii) options, futures, or forward contracts (other than options,
futures, or forward contracts on foreign currencies), or iii) foreign currencies
(or options, futures, or forward contracts on foreign currencies) but only if
such currencies are not directly related to the Fund's business of investing in
stock, securities or options and futures thereon. Accordingly, the extent to
which a Fund may engage in futures contracts and related options may be
materially limited by this 30% test. C. Each Fund must diversify its holdings so
that, at the end of each fiscal quarter: i) at least 50% of the market value of
the Fund's total assets is represented by cash, U.S. Government securities and
other securities, with such other securities limited, with respect to any one
issuer, to an amount not greater than 5% of the Fund's total assets and not more
than 10% of the outstanding voting securities of such issuer, and ii) not more
than 25% of the value of its total assets is invested in the securities of any
one issuer (other than U.S. Government securities).

Each Fund intends to satisfy requirements under the Code relating to the
distribution of its net income so that, in general, a Fund will not be subject
to Federal income tax (FIT) on its investment company taxable income and net
capital gains designated by the Fund as capital gain dividends, if any, that it
distributes to shareholders on a timely basis. Each Fund intends to distribute
to its shareholders, at least annually, substantially all of its investment
company taxable income and any net capital gains.

Each Fund is subject to a nondeductible 4% excise tax if it does not meet
certain distribution requirements under the Code.  To avoid this excise tax,
during each calendar year, a Fund must distribute: 1) at least 98% of its
ordinary income (not taking into account any capital gains or losses) for the
calendar year, 2) at least 98% of its capital gains in excess of its capital
losses for the twelve month period ending on October 31 of the calendar year,
and 3) all ordinary income and capital gains from previous years that were not
distributed during such years.

Dividends declared to shareholders of record on a date in October, November or
December will be taxable to shareholders in the year declared as long as the
Fund pays the dividends no later than January of the following year.

Section 1092 of the Code affects the taxation of certain transactions involving
futures or options contracts.  If a futures or options contract is part of a
"straddle" (which could include another futures or options contract or
underlying stock or securities), as defined in Section 1092 of the Code, then,
generally, losses are deferred first, to the extent that the modified "wash
sale" rules of the Section 1092 regulations apply, and second to the extent of
unrecognized gains on offsetting positions.  Further, a Fund may be required to
capitalize, rather than deduct currently, any interest expense on indebtedness

CIGNA Funds Group/CIGNA Institutional Funds Group                  Page 26
<PAGE>
 
incurred or continued to purchase or carry any positions that are part of a
straddle.  Sections 1092 and 246 of the Code and the Regulations thereunder also
suspend the holding periods for straddle positions with possible adverse effects
regarding long-term capital gain treatment and the corporate dividends-received
deduction.  In certain cases, the "wash sale" rules of Section 1091 of the Code
may operate to defer deductions for losses.

Section 1256 of the Code generally requires that certain futures and options be
"marked-to-market" at the end of each year for FIT purposes.  Section 1256
further characterizes 60% of any gain or loss with respect to such futures and
options as long-term capital gain or loss and 40% as short-term capital gain or
loss.  If such a future or option is held as an offsetting position and can be
considered a straddle under Section 1092 of the Code such a straddle will
constitute a mixed straddle.  A mixed straddle will be subject to both Section
1256 and Section 1092 unless certain elections are made by the Fund.

Upon a sale or redemption of Fund shares, a shareholder who is not a dealer in
securities will realize gain or loss which will be treated as long-term capital
gain or loss if the shares have been held for more than one year, and otherwise
as short-term capital gain or loss. However, if a shareholder disposes of shares
held for six months or less, any loss realized will be characterized as long-
term capital loss to the extent of any capital gain dividends made to such
shareholder prior to such disposition. In addition, shareholders need to
consider the general wash sale rule which may impact shareholders who sell their
shares at a loss and purchase shares within a sixty-one day time frame.

The Funds may invest in certain foreign currency transactions which may be
subject to taxation under Section 988.

International Stock Fund
- ------------------------

If more than 50% of the value of the Fund's total assets consist of foreign
stock or securities at the close of its taxable year, the Fund may elect to pass
through the credit or deduction for foreign taxes to shareholders who are U.S.
persons (i.e., U.S. citizens and residents and U.S. domestic corporations,
partnerships, trusts, and estates).  As a result, shareholders who want to take
the benefit of the foreign tax credit or deduction on their U.S. income tax
returns would include in gross income, in addition to taxable dividends actually
received from the Fund, their proportionate share of foreign taxes paid by the
Fund.  If the Fund makes such an election, it will report to shareholders,
shortly after the end of the taxable year, their proportionate share of gross
foreign source income and foreign taxes paid by the Fund.

The Fund may invest in shares of stock of a foreign entity which is classified
under the Internal Revenue Code as a Passive Foreign Investment Company
("PFIC").  Investments in PFIC's may affect the 

CIGNA Funds Group/CIGNA Institutional Funds Group                  Page 27
<PAGE>
 
character of gains, the timing of recognition of gains or losses, and the amount
of gains or losses recognized. In addition, such investments may subject the
Fund to a U.S. federal income tax which cannot currently be eliminated by making
distributions to Fund shareholders.

A foreign corporation may be classified as a PFIC for a taxable year if 75% or
more of its gross income is passive income or the average holdings of assets
that produce passive income is at least one half of its total assets.  Passive
income would include investment income, including but not limited to, interest
and dividend income.  Under IRS rules, the Fund may be taxed on its share of
gain from a disposition of the PFIC stock, or an excess distribution from the
PFIC stock whether or not the income is distributed by the Fund to its
shareholders.  In general, such gains or excess distributions are held to be
earned ratably over the period the Fund held the PFIC stock.  Amounts allocated
to the Fund's prior taxable years will be taxed at the highest corporate rate in
effect for that year and an interest factor will be added to the tax.  Excess
distributions and gains from the disposition of the PFIC stock are treated as
ordinary income.

Where feasible, the Funds intend to make either (1) a qualified electing fund
("QEF") election or (2) a mark-to-market election under IRS rules in order to
avoid the imposition of a Fund level tax on its PFIC holdings.

If a QEF election is made the Fund must include in its gross income its share of
the ordinary earnings and net capital gains from the PFIC shares in the year
that the election is made (and all future years the PFIC stock is held)
regardless of whether distributions are received from the PFIC in the current
year.  This income would then be passed through to shareholders.

Under a mark-to-market election, if the fair market value ("FMV") of the Fund's
PFIC shares at the end of its taxable year is greater than the FMV of the shares
at the beginning of its taxable year (or the date of purchase whichever is
later), the difference will be included in the Fund's gross income whether or
not the Fund's shares are sold in that year.  This income would then be passed
through to shareholders as ordinary income.  Any mark-to-market gain recognized
by the Fund would be added to its tax basis in the PFIC shares.  If, however, as
of the end of the Fund's taxable year the FMV of the PFIC shares has decreased
relative to their FMV at the beginning of the year (or the date of purchase
whichever is later), the Fund would not be entitled to recognize the loss.

Shareholders who are not U.S. persons (i.e., U.S. citizens and residents and
U.S. domestic corporations, partnerships, trusts and estates) should consult
their tax advisers regarding U.S. and foreign tax consequences of ownership of
shares of the Fund including the likelihood that distributions to them would be
subject to withholding of U.S. tax at a rate of 30% (or at a lower rate under a
tax treaty).


CIGNA Funds Group/CIGNA Institutional Funds Group                  Page 28
<PAGE>
 
The Funds will engage in certain foreign currency transactions which may be
subject to taxation under Section 988.  Generally, Section 988 requires that
most foreign currency gains and losses be treated as ordinary income and loss,
not capital gain and loss.

Due to the nature of the Funds' investment objectives, it is anticipated that
none of the Fund's ordinary dividends will qualify for the 70% dividends
received deduction for corporate shareholders.

ACTIVITIES OF AFFILIATED COMPANIES
- ----------------------------------

From time to time, as purchases of securities are made for the portfolios of
companies affiliated with CIGNA Corporation it is possible that two or more
portfolios may simultaneously purchase or sell the same security. To the extent
that two or more such portfolios, buying or selling the same security, increase
the total demand or supply, there may be an adverse effect on the price of such
security or on the amount which the Fund can purchase or sell.

INVESTMENT ADVISORY AND OTHER SERVICES
- --------------------------------------

The investment adviser to each of the Funds is CII, an indirect, wholly-owned
subsidiary of CIGNA Corporation. CIIA serves as investment sub-adviser to the
International Stock Fund.  CII also serves as investment adviser for other
investment companies sponsored by affiliates of CIGNA Corporation, and for a
number of pension, advisory, corporate and other accounts. CII and other
affiliates of CIGNA Corporation manage combined assets of over $70 billion.
CII's mailing address is 900 Cottage Grove Road, Hartford, Connecticut 06152.

Pursuant to Master Investment Advisory Agreements between the Trusts and CII,
CII manages the investment and reinvestment of the assets of the Funds.

Subject to the control and periodic review of the Board of Trustees of the
Trusts, CII (CIIA in the case of the International Stock Fund, Emerging Markets
Stock Fund, Developed Markets Stock Fund and Global Bond Fund) determines what
investments shall be purchased, held, sold or exchanged for the account of the
Funds, and what portion, if any, of the assets of the Funds shall be held in
cash and other temporary investments.  Accordingly, the role of the Trustees is
not to approve specific investments, but rather to exercise a control and review
function.

The Trusts pay all expenses not specifically assumed by CII including
compensation and expenses of Trustees who are not Directors, officers or
employees of CII or any other affiliates of CIGNA Corporation; investment
management fees; registration, filing and other fees in connection with filings
with regulatory authorities; the fees and expenses of independent accountants;
costs of printing and mailing registration statements, prospectuses, proxy
statements, and annual and periodic reports to shareholders; custodian and
transfer agent fees; brokerage commissions and securities transactions costs
incurred by the Trust; taxes and corporate fees; legal fees incurred in
connection with the affairs of the Trust; expenses of meetings of the
shareholders and Trustees; and any expenses allocated or allocable to a specific
class of shares.
    
CII, at its own expense, furnishes to the Trusts office space and facilities
and, except with respect to the Office of the Treasurer and Office of the
Secretary as provided in the Master Investment Advisory Agreements, all
personnel for managing the affairs of the Trust and each of Funds.  The Trusts
and other registered investment companies advised by CII have agreed to
reimburse CII for its costs of maintaining the Office of the Treasurer and the
cost of the Office of the Secretary as provided in their respective investment
advisory agreements.  CII has estimated that in 1997 the total expenses of the
Office of the Treasurer will not exceed $337,000 and the expenses of the Office
of the Secretary are not expected to exceed $94,000.  The portion

of these expenses allocated to each Fund for calendar year 1997 are not expected
to exceed the following amounts:

In 1996 the costs reimbursed by the Trusts for the Office of the Treasurer and
the Office of the Secretary were $36,188 and $9,766, respectively.     

The Board of Trustees of the Trust has approved the method under which this cost
will be allocated to the Trust, and then to each Fund.

As full compensation for the investment management and all other services
rendered by CII and any sub-adviser, each Fund pays CII a separate fee computed
daily and paid monthly at annual rates based on a percentage of the value of the
relevant Fund's average daily net assets, as follows:  Income Fund - 0.50%; High
Yield Fund -0.75%; Money Market Fund - 0.35%; Governmental Obligations Cash Fund
- - 0.35%, Treasury Obligations Cash Fund - 0.35%; S&P 500 Index Fund - 0.25%;
Government Securities Fund - .50%; International Stock Fund - 0.80%.  Reflecting
the specialized nature of their investment policies, the management fees paid by
the High Yield, International Stock, Emerging Markets Stock, Developed Markets
Stock and Global Bond Funds exceed those paid by most other investment
companies.  These fees, however, are comparable to those paid by funds with
similar investment objectives.
    
Trust-wide expenses not identifiable to any particular Fund will be allocated
among the Funds.  CII has voluntarily agreed, until April 30, 1998, to reimburse
the Funds to the extent that the annual operating expenses in any one year
(excluding interest,      


CIGNA Funds Group/CIGNA Institutional Funds Group                  Page 35

taxes, amortized organizational expense, transaction costs in acquiring and
disposing of portfolio securities and extraordinary expenses) of a Fund exceed a
percentage of the value of the relevant Fund's average daily net assets, as
follows:

CIGNA Institutional Funds Group incurred a management fee payable to CII of
$63,000, $57,492 and $56,609 in 1996, 1995 and 1994, respectively.  However, due
to the expense limitation, CII waived these fees and reimbursed an additional
$53,870, $46,590 and $25,412 to the Fund in 1996, 1995 and 1994, respectively.
     
    
CIGNA Money Market Fund incurred a management fee of $111,530, $26,892 and
$92,369 in 1996, 1995 and 1994, respectively.  However, due to the expense
limitation, CII waived $78,697 of this fee in 1996 and waived its management
fees and reimbursed $23,194 and $19,546 to the Fund in 1995 and 1994,
respectively.      
    
CIGNA Income Fund incurred a management fee of $5,465, $25,580 and $86,634 in
1996, 1995 and 1994, respectively. However, due to the expense limitation, CII
waived these fees and reimbursed $44,851 in 1996 and reimbursed $21,690 and
$45,267 to the Fund in 1995 and 1994, respectively.     

Each Master Investment Advisory Agreement provides that it will continue from
year to year as to a Fund provided that such continuance is specifically
approved at least annually: (a) by a vote of the "majority of the outstanding
voting securities" (as such term is defined in the 1940 Act) of that Fund or by
the Board of Trustees of the Trust, and (b) by a vote of a majority of the
Trustees who are not parties to the agreement or "interested persons" (as
defined in the 1940 Act) of any party thereto, cast in person at a meeting
called for the purpose of voting on such approval.  Each Master Investment
Advisory Agreement provides that it (i) may be terminated at any time without
penalty (a) upon 60 days' written notice by vote of the Trustees of the Trust,
or with 

CIGNA Funds Group/CIGNA Institutional Funds Group                  Page 36
<PAGE>
 
respect to any Fund, by vote of a majority of the outstanding voting securities
of such Fund, or (b) by CII upon 90 days' written notice to the Trust in the
case of the Master Investment Advisory Agreement and (ii) will automatically
terminate in the event of its "assignment" (as such term is defined in the 1940
Act).

Each Master Trust Agreement acknowledges CIGNA Corporation's control over the
name "CIGNA". The Trust and the Fund would be obliged to change their names to
eliminate the word "CIGNA" (to the extent they could lawfully do so) in the
event CIGNA Corporation were to withdraw its permission for use of such name.
CIGNA Corporation has agreed not to withdraw such permission from the Trust or a
series of the Trust so long as an affiliate of CIGNA Corporation shall be the
investment adviser for such series.

The Trusts' Custodian and Transfer Agent is State Street Bank and Trust Company
("State Street"), Boston, Massachusetts 02107.  Under its Custodian Agreement,
State Street maintains the portfolio securities of each Fund, administers the
purchases and sales of portfolio securities, collects interest and dividends and
other distributions made on the securities held in the portfolio, determines the
net asset value of shares of each Fund on a daily basis and performs such other
ministerial duties as are included in the Custodian Agreement and Agency
Agreement, copies of which are on file with the Securities and Exchange
Commission.
    
Price Waterhouse LLP acts as independent accountants for the Trusts.  Its
offices are at 160 Federal Street, Boston, Massachusetts 02110.  Price
Waterhouse LLP representatives annually perform an audit of the financial
statements of the Funds and provide accounting advice and services throughout
the year.  Price Waterhouse LLP reports its activities and the results of its
audit to the Audit Committee of the Board of Trustees.  Price Waterhouse LLP
also provides certain tax advice to the Trusts.     

PORTFOLIO TURNOVER AND BROKERAGE ALLOCATION
- -------------------------------------------

It is anticipated that each Fund's annual portfolio turnover rate will not
exceed 100%.

With respect to Fund transactions, it is the policy of CII and CIIA (the
"Advisers") on behalf of their clients, including the Funds, to have purchases
and sales of portfolio securities executed at the most favorable prices,
considering all costs of the transaction, including brokerage commissions and
spreads, and research services, consistent with obtaining best execution.

In seeking best execution, the Advisers will select brokers/dealers on the basis
of their professional capability and the value and quality of their brokerage
services.  Brokerage services include the ability to execute most effectively
large orders without adversely affecting markets and the positioning of
securities in order to effect orderly sales for clients.


CIGNA Funds Group/CIGNA Institutional Funds Group                  Page 37
<PAGE>
 
The officers of the Advisers will determine, generally without limitation, the
brokers/dealers through whom, and the commission rates or spreads at which,
securities transactions for client accounts are executed.  The officers of the
Advisers may select a broker/dealer who may receive a commission for portfolio
transactions exceeding the amount another broker/dealer would have charged for
the same transaction if they determine that such amount of commission is
reasonable in relation to the value of the brokerage or research services
performed or provided by the executing broker/dealer, viewed in terms of either
that particular transaction or the Advisers' overall responsibilities to the
client for whose account such portfolio transaction is executed and other
accounts advised by the Advisers or accounts advised by other investment
advisers which are related persons of the Advisers.

A portion of the securities in which certain Funds invest may be traded in over-
the-counter ("OTC") markets, and in such transactions, the Fund deals directly
with the dealer who makes markets in the securities involved, except in those
circumstances where better prices and executions are available elsewhere.
Portfolio transactions placed through dealers serving as primary market makers
are effected at net prices, without commissions as such, but which include
compensation in the form of mark up or mark down.

Foreign equity securities may be held by a Fund in the form of American
Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") or other
securities representing underlying securities of foreign issuers, or securities
convertible into foreign equity securities.  These securities may not
necessarily be denominated in the same currency as the securities into which
they converted.  ADRs are securities issued by a foreign corporation.  EDRs are
receipts issued in Europe which evidence a similar ownership arrangement.
Generally, ADRs, in registered form, are designed for use in the United States
and EDRs may be listed on stock exchanges, or traded in OTC markets in the
United States or Europe, as the case may be.  ADRs, like other securities traded
in the United States, will be subject to negotiated commission rates.

If two or more brokers/dealers are considered able to offer the same favorable
price with the equivalent likelihood of best execution, the officers of the
Advisers may prefer the broker/dealer who has furnished research services.
Research services include market information, analysis of specific issues,
presentation of special situations and trading opportunities on a timely basis,
advice concerning industries, economic factors and trends, portfolio strategy
and performance of accounts.  Research services are used in advising all
accounts, including accounts advised by related persons of the Advisers, and not
all such services are necessarily used by the Advisers in connection with the
specific account that paid commissions to the broker/dealer providing such
services.

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 38
<PAGE>
 
The overall reasonableness of brokerage commissions paid is evaluated
continually.  Such evaluation includes review of what competing brokers/dealers
are willing to charge for similar types of services and what discounts are being
granted by brokerage firms.  The evaluation also considers the timeliness and
accuracy of the research received.
    
In addition, the Advisers may, if permitted by applicable law, use brokerage
commissions to pay for products or services (other than brokerage and research
services) obtained from broker/dealers and third parties in accordance with SEC
Release 34-23170 dated April 23, 1986. Pursuant to that Release, products and
services which provide lawful and appropriate assistance to the Advisers'
investment decision-making process may be paid for with brokerage commissions to
the extent such products and services are used in that process. Where the
research service product has a mixed use, that is, the product may serve a
number of functions certain of which are not related to the making of investment
decisions, the Advisers allocate the cost of the product on a basis which they
deem reasonable, according to the various uses of the product, and maintain
records documenting the allocation process followed. Only that portion of the
cost of the product allocable to research services is paid through credit earned
from the Fund's brokerage business. The Advisers will not acquire research
services through the generation of credits with respect to the Funds' principal
transactions or transactions in financial futures, except in new issue fixed
price underwritings. During 1994, 1995 and 1996, brokerage commissions paid by
the CIGNA Institutional Funds Group amounted to $56,609, $47,611 and $32,798,
respectively, substantially all of which was paid to firms which provide
research services to the Advisers. CIGNA Money Market Fund and CIGNA Income Fund
paid no brokerage commissions in 1994, 1995 or 1996.     
    
As of December 31, 1996, Sanford C. Bernstein & Co., Inc. ("SCB") reported
ownership of approximately 8.1% of the outstanding common stock of CIGNA
Corporation.  Accordingly, CIGNA may be deemed to be an affiliated person of SCB
pursuant to the provisions of the 1940 Act.   As long as CIGNA may be deemed to
be an affiliated person of SCB, a Fund will not engage in any transaction with
SCB when SCB is acting for its own account and will engage in brokerage
transactions with SCB only under circumstances where the commission, spread or
profit received by the broker is fair and reasonable pursuant to rules
established by the Securities and Exchange Commission and procedures adopted and
monitored by the Board of Trustees of the Trust.  During 1996, the Funds did not
engage in brokerage transactions with SCB.     

Neither the Trust nor the Advisers presently allocate brokerage commissions to,
or place orders for portfolio transactions with, 

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 39
<PAGE>
 
either directly or indirectly, brokers or dealers based on their sales of Fund
shares. Except as noted, neither the Trust nor the Advisers utilize an
affiliated broker or dealer in effecting Fund portfolio transactions and do not
recapture commissions paid in such transactions.

PURCHASE, REDEMPTION AND PRICING OF SECURITIES
- ----------------------------------------------

Each Fund reserves the right to revise its redemption procedures on 30-days'
notice.  Each Fund may suspend redemptions or postpone the date of payment
during any period when:  (a) the New York Stock Exchange is closed for other
than customary weekend and holiday closings or trading on such Exchange is
restricted; (b) the Securities and Exchange Commission has by order permitted
such suspension for the protection of the Fund's shareholders; or (c) an
emergency exists as determined by the Securities and Exchange Commission making
disposal of portfolio securities or valuation of net assets of the Fund not
reasonably practicable.

A Fund's net asset value is calculated by dividing the number of outstanding
shares into the net assets of the Fund.  Net assets are the excess of a Fund's
assets over its liabilities.
    
Money Market Funds.  The investments of the Money Market Funds are generally
- -------------------                                                         
valued at amortized cost.  The amortized cost of an instrument is determined by
valuing it at cost originally and thereafter amortizing any discount or premium
from its face value at a constant rate until maturity, regardless of the effect
of fluctuating interest rates or other factors on the market value of the
instrument.  The amortized cost method may result at times in determinations of
value that are higher or lower than the price the Fund would receive if the
instruments were sold.  During periods of declining interest rates, use by the
Fund of the amortized cost method of valuing its portfolio may result in a lower
value than the market value of the portfolio, which could be an advantage to new
investors relative to existing shareholders.  The converse would apply in a
period of rising interest rates.     
    
The valuation of the investments of the Money Market Funds at amortized cost is
permitted by the Securities and Exchange Commission, and the Funds are required
to adhere to certain conditions so long as they use this valuation method.  The
Money Market Funds will maintain a dollar-weighted average portfolio maturity of
90 days or less, will purchase only instruments having remaining maturities of
397 days or less (except as permitted under Rule 2a-7 of the 1940 Act with
respect to variable and floating rate instruments) and will invest only in
securities determined by the Board of Trustees to be of high quality with
minimal credit risks.  The Board of Trustees has also established procedures
reasonably designed, taking into account current market conditions and the
Fund's investment objective, to stabilize the Fund's price per share as computed
for the purpose of distribution, redemption and repurchase at $1.00.  Such
procedures      

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 40
<PAGE>
 
include a review of the Fund's portfolio holdings by the Board of Trustees, at
such intervals as they may deem appropriate, to determine whether the Fund's net
asset value, calculated by using readily available market quotations, deviates
from $1.00 per share, and, if so, whether such deviation may result in material
dilution or is otherwise unfair to existing shareholders. In the event the Board
of Trustees determines that such a deviation exists, it will take such
corrective action as it deems necessary and appropriate, including selling
portfolio instruments prior to maturity to realize capital gains or losses or to
shorten average portfolio maturity; withholding dividends; redeeming shares in
kind; or establishing a net asset value per share by using readily available
market quotations in which case, the net asset value could possibly be greater
or less than $1.00 per share.

PERFORMANCE INFORMATION
- -----------------------

Total return figures for the Funds are neither fixed nor guaranteed, and a
Fund's principal is not insured.  Performance quotations reflect historical
information and should not be considered representative of a Fund's performance
for any period in the future.  Performance is a function of a number of factors
which can be expected to fluctuate.  Each Fund may provide performance
information in reports, sales literature and advertisements.  Each Fund may
also, from time to time, quote information about the Fund published or aired by
publications or other media entities which contain articles or segments relating
to investment results or other data about the Fund.  The following is a list of

</TABLE> 

Each Fund May also compare its performance to rates on Certificates of Deposit
and other fixed rate investments such as the following:

   10 year Treasuries
   30 year Treasuries
   90 day Treasury Bills

Advertising for a Fund may from time to time include discussions of general
economic conditions and interest rates, and may also include references to the
use of those Funds as part of an individual's overall retirement investment
program.  From time to time, sales literature and/or advertisements for any of
the Funds may disclose the largest holdings in the Fund's portfolio.

From time to time, the Funds' sales literature and/or advertisements may discuss
generic topics pertaining to the mutual fund industry.  This includes, but is
not limited to, literature addressing general information about mutual funds,
variable annuities, dollar-cost averaging, stocks, bonds, money markets,
certificates of deposit, retirement, retirement plans, asset allocation, tax-
free investing, college planning, inflation.

Although performance data may be useful to prospective investors in comparing
with other funds and other potential investments, investors should note that the
methods of computing performance of other potential investments are not
necessarily comparable to the methods employed by the Fund.

Total Return Quotations
- -----------------------

The standard formula for calculating total return, as described in the
prospectus, is as follows:
                                 P(1+T)/n/=ERV
 
Where P      = A hypothetical initial payment of $1,000.
      T      = average annual total return.
      n      = number of years.
      ERV    = ending redeemable value of a hypothetical $1,000 payment at the
               end of the 1, 5, or 10 year periods (or fractional portion of
               such period).

Cumulative total return across a stated period may be calculated as follows:
 
                              P(1+V)=ERV
 
Where P     = A hypothetical initial payment of $1,000.
      V     = cumulative total return.
      ERV   = ending redeemable value of a hypothetical $1,000 payment at the
              end of the stated period.
     
The average annual total returns for each of the named Funds, for the 1, 5 and
10 year periods (or since inception, if shorter) ended December 31, 1996, were
as follows:

*The inception date of CIGNA International Stock Fund was January 11, 1993.  Its
average annual return since inception was 12.80%.       

Yield Quotations
- ----------------

The standard formula for calculating yield for each Fund except the CIGNA Money
Market Funds, as described in the Prospectus, is as follows:

                      YIELD = 2[((a-b)/(c x d) + 1)/6/-1]
 
Where a =   dividends and interest earned during a stated 30-day period. For
            purposes of this calculation, dividends are accrued rather than
            recorded on the ex-dividend date. Interest earned under this formula
            must generally be calculated based on the yield to maturity

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 43
<PAGE>
 
            of each obligation (or, if more appropriate, based on yield to call
            date). 

b =         expenses accrued during period (net of reimbursements).
 
c =         the average daily number of shares outstanding during the period
            that were entitled to receive dividends.
             
d =         the maximum offering price per share on the last day of the period.

The yield for CIGNA Income Fund was as follows:

    
                                       30 Days ended December 31, 1996
                                       -------------------------------

   CIGNA Income Fund........................            5.09%     


The standard formula for calculating annualized yield for the CIGNA Money Market
Fund, as described in the Prospectus, is as follows:

                               Y = V\1\ - V\o\ x 365
                                   -----------   ---
 
Where      Y    =  7 day annualized yield.
           V\o\ =  the value of a hypothetical pre-existing account in the Fund
                   having a balance of one share at the beginning of a stated
                   seven-day period.
                    
           V\1\ =  the value of such an account at the end of the stated period.
 
         V\1\ - V\o\ =  base period return.
         -----------
           V\o\
    
The annualized yield for the CIGNA Money Market Fund for the 7 days ended
December 31, 1996 was 4.97%.     

The standard formula for calculating effective annualized yield for the CIGNA
Money Market Funds, as described in the Prospectus, is as follows:

                            EY = [(Y+1)/365/7/] - 1

Where EY   =    effective annualized yield.
      Y    =    base period return.

    
The effective annualized yield for CIGNA Money Market Fund for the 7 days ended
December 31, 1996 was 5.09%.     

For the purpose of the annualized yield and effective annualized yield, the net
change in the value of the hypothetical CIGNA Money Market Fund account reflects
the value of additional shares purchased 

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 44
<PAGE>
 
with dividends from the original shares and any such additional shares, and all
fees charged (if any), other than non-recurring account charges, to all
shareholder accounts in proportion to the length of the base period and the
Fund's average account size, but does not include realized gains and losses or
unrealized appreciation and depreciation.

REDEMPTIONS PAID IN CASH
- ------------------------

Pursuant to Rule 18f-1 under the Investment Company Act of 1940, as amended,
each Fund has committed to pay in cash all requests for redemption by any
shareholder of record, limited in amount with respect to each shareholder during
any 90 day period to the lesser of $250,000 or 1% of the net assets of the Fund
at the beginning of such period.  This election is irrevocable while such Rule
is in effect unless the Securities and Exchange Commission by order upon
application permits the withdrawal of the Fund's notification of election.
Redemptions by any one shareholder during any 90 day period in excess of
$250,000 or 1% of the net assets of the Fund may be made in readily marketable
securities.

CLASSES OF SHARES
- -----------------

Each Fund offers two classes of shares:  the institutional class and the retail
class.  Retail class shares pay service fees to CIGNA Financial Advisors, Inc.
("CFA"), its affiliates or independent service providers for services provided
to shareholders of that class.

Each Trust has adopted a Dual Class Plan pursuant to Rule 18f-3 under the 1940
Act.  Under the Plan, shares of each class of a Fund represent an equal pro rata
interest in such Fund and, generally, have identical voting, dividend,
liquidation, and other rights, preferences, powers, restrictions, limitations,
qualifications and terms and conditions, except that:  (a) each class has a
different designation; (b) each class of shares bears any class-specific
expenses allocated to it; and (c) the retail class has exclusive voting rights
on any matter submitted to shareholders that relates solely to its service
arrangement, and each class has separate voting rights on any matter submitted
to shareholders in which the interests of one class differ from the interests of
any other class.

UNDERWRITER
- -----------

CFA serves as the Trusts' distributor pursuant to Distribution Contracts
("Distribution Contracts") which are subject to annual approval by the Board of
Trustees.  CFA is an indirect, wholly-owned subsidiary of CIGNA Corporation.
The Distribution Contract is terminable with respect to a Fund without penalty,
at any time, by the Trust upon 60 days' written notice to CFA or by CFA upon 60
days' notice, to the Trust.  CFA is not obligated to sell any specific 

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 45
<PAGE>
 
amount of Trust shares. Pursuant to the Distribution Contracts, CFA continuously
offers Fund shares.

SERVICE FEES
- ------------

Each Trust has adopted an Administrative Services Plan with respect to the
retail class shares of each Fund.  Under the terms of each Plan, the Trusts are
permitted to pay CFA, its affiliates or independent service provides, out of the
retail class assets of each Fund, for providing services such as receiving,
aggregating and processing shareholder orders; furnishing shareholder sub-
accounting; providing and maintaining retirement plan records; acting as the
sole shareholder of record and nominee for shareholders; communicating
periodically with shareholders and forwarding shareholder communications;
maintaining accounting records for shareholders; answering questions and
handling correspondence from shareholders about their accounts; and performing
similar account administrative services.

Each Plan provides that it may not take effect until approved by vote of a
majority of both (i) the Trustees of the Trust and (ii) the Trustees
unaffiliated with CIGNA Corporation (the "Plan Trustees"). The Plans were
approved by the Trustees, including the Plan Trustees, at a meeting held 
April 30, 1996.

Each Plan provides that any person authorized to direct the disposition of
monies paid or payable by a class pursuant to the Plan or any related agreement
shall provide to the Trustees, and the Board shall review at least quarterly, a
written report of the amounts so expended and the purposes for which such
expenditures were made.


DESCRIPTION OF MONEY MARKET INSTRUMENTS
- ---------------------------------------

U.S. GOVERNMENT DIRECT OBLIGATIONS--issued by the U.S. Treasury and include
bills, notes, and bonds.

      -  Treasury bills are issued with maturities of up to one year.  They are
         issued in bearer form, are sold on a discount basis and are payable
         at par value at maturity.

      -  Treasury notes are longer-term interest bearing obligations with
         original maturities of one to ten years.

      -  Treasury bonds are longer-term interest bearing obligations with
         original maturities from ten to thirty years.

BANKERS' ACCEPTANCES--A bankers' acceptance is a bill of exchange or time draft
drawn on and accepted by a commercial bank.  It is used by corporations to
finance the shipment and storage of goods and to furnish dollar exchange.  When
the draft is accepted by a bank, the bank guarantees to pay the face value of
the instrument on its 

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 46
<PAGE>
 
maturity date. An investor can purchase a bankers' acceptance in the secondary
market at the going rate of discount for a specific maturity. In addition to
purchasing bankers acceptances from domestic branches and foreign branches of
U.S. commercial banks, bankers' acceptances denominated in each case in U.S.
dollars, may be purchased from foreign branches and U.S. branches of foreign
banks having at least one billion dollars (U.S.) of assets. Maturities are
generally six months or less.

CERTIFICATES OF DEPOSIT--A certificate of deposit (CD) is a negotiable interest-
bearing instrument with a specific maturity.  Certificates of deposit are issued
by banks and savings and loan institutions in exchange for the deposit of funds
and normally can be traded in the secondary market, prior to maturity.  The Fund
may invest in U.S. dollar denominated CD's issued by domestic branches and
foreign branches of U.S. banks which are members of the Federal Reserve System;
by foreign branches and U.S. branches of foreign banks and by U.S. domiciled
savings and loan institutions having in each case at least one billion dollars
(U.S.) of assets.  CD's issued by foreign branches of U.S. banks are called
"Eurodollar CD's" while CD's issued by U.S. branches of foreign banks are called
"Yankee CD's."

TIME DEPOSITS--A time deposit is a non-negotiable receipt issued by a bank in
exchange for the deposit of funds.  Like a certificate of deposit, it earns a
specified rate of interest over a definite period of time; however, it cannot be
traded in the secondary market.  Time deposits denominated in U.S. dollars or
other currencies may be purchased from domestic branches and foreign branches of
U.S. banks which are members of the Federal Reserve System (not including
savings and loan institutions) and from foreign branches and U.S. branches of
foreign banks having at least one billion dollars (U.S.) of assets.  The Fund
shall not invest in time deposits maturing in more than seven days.

U.S. dollar denominated certificates of deposit, time deposits and bankers'
acceptances issued by foreign branches of U.S. banks or by foreign banks either
in the U.S. or abroad may present investment risks in addition to the risks
involved in investments in obligations of, or guaranteed by, domestic banks.
Such risks include future political and economic developments, the possible
imposition of withholding taxes on interest income payable on such obligations,
the possible seizure or nationalization of foreign deposits, the possible
establishment of exchange controls or the adoption of other governmental
restrictions.  Generally, foreign branches of U.S. banks and U.S. branches of
foreign banks are subject to fewer U.S. regulatory restrictions than are
applicable to domestic banks, and foreign branches of U.S. banks may be subject
to less stringent reserve requirements than domestic banks.  U.S. branches of
foreign banks and foreign branches of U.S. banks may provide less public
information than, and may not be subject to the same accounting, auditing and
financial record-keeping standards as, domestic banks.  Foreign branches of
foreign banks generally would not be subject to 

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 47
<PAGE>
 
any U.S. regulatory restrictions or disclosure, financial record-keeping or
accounting requirements.

COMMERCIAL PAPER--Commercial paper is the term used to designate unsecured
short-term promissory notes issued by corporations and other business entities.
Maturities on these issues vary from a few days to nine months.  Commercial
paper may be purchased from U.S. domiciled issuers.  Commercial paper may also
be purchased from foreign issuers issued either in the U.S. ("Yankee" commercial
paper) or abroad.

OTHER CORPORATE OBLIGATIONS--The Fund may purchase notes, bonds and debentures
issued by corporations and other business entities if at the time of purchase
there is less than one year remaining until maturity or if they carry a variable
or floating rate of interest.

VARIABLE AND FLOATING RATE INSTRUMENTS--Certain debt instruments in which the
Fund invests may carry variable or floating rates of interest.  Such instruments
bear interest at rates which are not fixed, but which vary with changes in
specified market rates or indices, such as a Federal Reserve composite index.

RATINGS OF SECURITIES
- ---------------------

Description of Standard & Poor's Corporation ("S&P") and Moody's Investors
Service, Inc.  ("Moody's") commercial paper and bond ratings:

COMMERCIAL PAPER RATINGS--S&P commercial paper ratings are graded into four
categories, ranging from "A" for the highest quality obligations to "D" for the
lowest.  Issues assigned an "A" rating are regarded as having the greatest
capacity for timely payment.  Issues in this category are delineated with the
numbers 1, 2, and 3 to indicate the relative degree of safety.  The two highest
categories, A-1 and A-2, are described as follows:

"A-1"      This designation indicates that the degree of safety regarding timely
           payment is either overwhelming or very strong.  Those issues
           determined to possess overwhelming safety characteristics will be
           denoted with a plus (+) sign designation.

"A-2"      Capacity for timely payment on issues with this designation is
           strong. However, the relative degree of safety is not as high as for
           issues designated "A-1."

Moody's employs three designations, all judged to be investment grade, to
indicate the relative repayment capacity of rated issuers.  The two highest
designations are as follows:

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 48
<PAGE>
 
Issuers rated Prime-1 (or related supporting institutions) have a superior
capacity for repayment of short-term promissory obligations.  Prime-1 repayment
capacity will normally be evidenced by the following characteristics:

     .  Leading market positions in well-established industries.

     .  High rates of return on funds employed.

     .  Conservative capitalization structures with moderate reliance on debt
        and ample asset protection.
 
     .  Broad margins in earnings coverage of fixed financial charges and high
        internal cash generation.

     .  Well-established access to a range of financial markets and assured
        sources of alternate liquidity.

Issuers rated Prime-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations.  This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.

Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

BOND RATINGS--S&P describes its ratings for corporate bonds as follows:

AAA - Debt rated AAA has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

AA  - Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.

A   - Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.

BBB - Debt rated BBB is regarded as having an adequate capacity to pay interest
and repay principal.  Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.

Moody's describes its ratings for bonds as follows:

CIGNA Funds Group/CIGNA Institutional Funds Group                       Page 49
<PAGE>
 
Aaa - Bonds which are rated Aaa are judged to be of the best quality.  They
carry the smallest degree of investment risk and are generally referred to as
"gilt-edge."  Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure.  While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues.

Aa  - Bonds which are 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.  They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in Aaa
securities.

A   - Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper medium grade obligations.  Factors giving security
to principal and interest are considered adequate but elements may be present
which suggest a susceptibility to impairment sometime in the future.

Baa - Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured.  Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time.  Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

The First Amended and Restated Master Trust Agreement, dated as of March 1, 1996
(the "Master Trust Agreement"), provides, among other things, for the
indemnification out of Registrant's assets (or the assets of a series of
Registrant where applicable) of the Trustees and officers of Registrant against
all liabilities incurred by them in such capacity, except for liability by
reason of wilful misfeasance, bad faith, gross negligence or reckless disregard
of their duties. Trustees may consult counsel or other experts concerning the
meaning and operation of the Master Trust Agreement, and may rely upon the books
and records of Registrant. Trustees are not liable for errors of judgment,
mistakes of fact or law, or for the negligence of other Trustees or Registrant's
officers or agents.

Trustees are not required to give a bond or other security for the performance
of their duties. Payments in compromise of any action brought against a Trustee
or officer may be paid by Registrant if approved by either a majority of
disinterested Trustees or by independent legal counsel. The right of
indemnification under the Master Trust Agreement is not exclusive of any other
rights to which the Trustees or officers may be entitled.

*    Filed herewith.
    
The Master Trust Agreement also provides that shareholders shall be indemnified
and held harmless by the applicable series of Registrant with respect to actions
brought against them in their capacity as shareholders. Also, the Master Trust
Agreement provides that creditors of a series of Registrant may look only to the
assets of that series for payment; and neither shareholders nor Trustees shall
be personally liable therefor. All instruments executed on behalf of Registrant
are required to contain a statement to the effect of the foregoing.     

CIGNA Investments, Inc., Registrant and other investment companies managed by
CIGNA Investments, Inc., their officers, trustees, directors and employees (the
"Insured Parties") are insured under an Investment Management Errors and
Omissions Insurance Policy in the amount of $10,000,000 offered by Lexington

the Trustees or the transfer agent may either issue receipts therefor or may
keep accounts upon the books of the  Trust for the record holders of such
shares, who shall in either case be deemed, for all purposes hereunder, to be
the holders of certificates for such shares as if they had accepted such
certificates and shall be held to have expressly assented and agreed to the
terms hereof.

          The Trustees may at any time authorize the issuance of share
certificates either in limited cases or to all shareholders.  In that event, a
shareholder may receive a certificate stating the number of shares owned by him
or her, in such form as shall be prescribed from time to time by the Trustees.
Such certificate shall be signed by the President or a Vice President and by the
Treasurer or an Assistant Treasurer.  Such signatures may be facsimiles if the
certificate is signed by a transfer agent, or by a registrar, other than a
Trustee, officer or employee of the Trust.  In case any officer who has signed
or whose facsimile signature has been placed on such certificate shall cease to
be

                                      -5-

such officer before such certificate is issued, it may be issued by the Trust
with the same effect as if he or she were such officer at the time of its issue.

          9.2  Loss of Certificates.  In case of the alleged loss or destruction
               --------------------                                             
or the mutilation of a share certificate, a duplicate certificate may be issued
in place thereof, upon such terms as the Trustees shall prescribe.

                --------------------------------------                      
transferred as collateral security shall be entitled to a new certificate if the
instrument of transfer substantially describes the debt or duty that is intended
to be secured thereby.  Such new certificate shall express on its face that it
is held as collateral security, and the name of the pledgor shall be stated
thereon, who alone shall be liable as a shareholder, and entitled to vote
thereon.

          9.4  Discontinuance of Issuance of Certificates.  The Trustees may at
               ------------------------------------------                      
any time discontinue the issuance of share certificates and may, by written
notice to each shareholder, require the surrender of shares certificates to the
Trust for cancellation.  Such surrender and cancellation shall not affect the
ownership of shares in the Trust.

she were not a Trustee, officer or agent; and the Trustees may accept
subscriptions to shares or repurchase shares from any firm or company in which
any Trustee, officer or other agent of the Trust may have an interest.
