                        Prospectus dated: May 1, 1996 
    

The Fund  Aetna Income Shares ("Income Shares" or "Fund") is a diversified, 
open-end management investment company whose shares are currently available 
to (i) variable annuity and variable life separate accounts to fund variable 
annuity contracts and variable life insurance policies issued by Aetna Life 
Insurance and Annuity Company (ALIAC) and its affiliates and subsidiaries and 
(ii) other shareholders of the Fund only through dividend reinvestment. 

Investment Objective  Income Shares seeks to maximize total return, 
consistent with reasonable risk, through investments in a diversified 
portfolio consisting primarily of debt securities. The Fund defines 
reasonable risk as the degree of risk of loss that an average investor would, 
in light of the fund's investment policies, be willing to tolerate in seeking 
to maximize total return. It is anticipated that capital appreciation and 
investment income will both be major factors in achieving total return.

contained in a Statement of Additional Information (SAI) dated May 1, 1996,

incorporated by reference. You can request an SAI, without charge, by writing 
to the Fund at the address listed above or by calling the Fund at 
1-800-367-7732. 
    

This Prospectus does not constitute an offer to sell, or a solicitation of an 
offer to buy, the securities of Income Shares in any jurisdiction in which 
such sale, offer to sell, or solicitation may not be lawfully made. 

LIKE ALL MUTUAL FUNDS, THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED

INVESTMENT OBJECTIVE 

Income Shares' investment objective is to maximize total return, consistent 
with reasonable risk, through investments in a diversified portfolio 
consisting primarily of debt securities. The Fund defines reasonable risk as 
the degree of risk of loss that an average investor would, in light of the 
fund's investment policies, be willing to tolerate in seeking to maximize 
total return. It is anticipated that capital appreciation and investment 
income will both be major factors in achieving total return. Income Shares' 
investment objective is fundamental and may not be changed without the vote 
of a majority of the outstanding voting securities as defined by the 
Investment Company Act of 1940 ("1940 Act"). There can be no assurance that 
the Fund will meet its investment objective. 

                     INVESTMENT POLICIES AND RESTRICTIONS 

Investment Policies  Income Shares will invest at least 65% of its total 
assets in debt securities. It is anticipated that the portfolio's effective 
average maturity will normally be between three and ten years. The Fund will 
normally invest at least 70% of its assets in one or more of the following: 

1) Debt securities or obligations (other than municipal securities) that are 
rated at the time of purchase within the four highest categories assigned by 
Moody's Investors Service, Inc. (Moody's), Standard & Poor's Corporation 
(Standard & Poor's) or other rating agencies, or, if not rated, that are 
considered by the Fund's investment adviser to be of comparable quality. For 
purposes of this policy, "debt securities or obligations" may include 
long-term obligations of, or guaranteed by, national or state banks, bank 
holding companies. 

2) Securities of, or guaranteed by, the U.S. Government, its agencies or 
instrumentalities. 

3) Marketable securities or obligations of, or guaranteed by, foreign 
governments (or any instrumentality thereof). 

4) Commercial paper and other short-term investments having a maturity of 
less than one year that are considered by the investment adviser to be 
investment grade. 

5) Cash or cash equivalents. 

Additionally, the Fund may invest in debt securities which have equity 
features, including convertible securities, which may be below investment 
grade; below investment grade debt securities; and preferred and common 
stocks. The Fund may also lend portfolio securities, write and repurchase 
covered call options, buy and sell covered put options and buy and sell 
interest rate futures contracts and options thereon for hedging purposes. The 
Fund may enter into repurchase agreements with domestic banks and 
broker-dealers. In addition, although the Fund's investment restrictions 
allow it to invest up to 15% of its total assets in illiquid securities 
(securities which cannot be sold in seven days without taking a materially 
reduced price), the Fund does not intend to invest more than 5% of its total 
assets in illiquid securities. 

The relative size of the Fund's investments in any grade or type of 
securities will vary from time to time depending on a number of factors, 
including yields, market supply and economic outlook. 

   
Based on Standard & Poor's bond ratings, the Fund had the following monthly 
weighted average distribution, by quality rating, for 1995: 

                           Rating           % 
                           ------------- ------ 
                           AAA              51 
                           AA                7 
                           A                14 
                           BBB              13 
                           BB                9 
                           B                 4 
                           Not Rated         2 
                                            ---- 
                                           100 
    

The relative amount of the Fund's investments which will be made in any 
particular grade or type of securities will vary from time to time depending 
upon a number of factors, including yield, market supply and economic 
outlook. The value of debt securities may be affected by changes in general 
interest rates. If interest rates increase, such securities tend to decline 
in value; if interest rates decline, the value of those securities will 
normally rise. Also, there is generally a greater risk associated with 
higher-yielding, lower-grade debt securities.

<PAGE>
 
Industry Concentration  The Fund will not concentrate its investments in any 
one industry, except that the Fund may invest up to 25% of its total assets 
in securities of companies principally engaged in any one industry. This 
limitation will not, however, apply to securities issued or guaranteed by the 
U.S. Government, its agencies and instrumentalities. Also, the Fund will not 
hold more than 5% of the value of its total assets in the securities of any 
one issuer or hold more than 10% of the outstanding voting securities of any 
one issuer. This restriction applies only to 75% of the value of the Fund's 
total assets and does not include securities issued or guaranteed by the U.S. 
Government, its agencies and instrumentalities. 

Asset-Backed Securities  The Fund may purchase securities collateralized by a 
specified pool of assets, including automobile loans, computer leases, boat 
loans, home equity loans, mobile home loans, recreational vehicles or credit 
card receivables. These securities are subject to prepayment risk. In periods 
of declining interest rates, reinvestment would thus be made at lower and 
less attractive rates. 

Borrowing  The Fund may borrow up to 5% of the value of its total assets for 
temporary or emergency purposes. The Fund does not intend to borrow for 
leveraging purposes; but it has the authority to do so; provided, 300% of the 
amount borrowed does not exceed the Fund's assets including the borrowings. 
Leveraging can increase the volatility of the Fund since it exaggerates the 
effects of changes in the value of the securities purchased with the borrowed 
funds. 

Options, Futures and Other Derivatives  The Fund may write covered call 
options and purchase covered put options, on securities and indexes. Put 
options will be acquired only for temporary defensive purposes. The Fund may 
purchase call options and sell put options to close out positions previously 
opened by the Fund. At any one time, the Fund may not have outstanding call 
options on more than 30% of its assets and it may not buy put options if more 
than 3% of the assets of the Fund would be invested in put options. 

The Fund may enter into futures contracts including stock index futures or 
options on futures contracts only for hedging purposes. The Fund may not 
enter into a futures contract if the current market prices of instruments 
required to be delivered and purchased under open futures contracts would 
exceed 30% of the Fund's assets. No more than 5% of the Fund's total assets 
may be committed to margin deposits on futures contracts. 

Income Shares may occasionally engage in hedging and other strategies using 
other types of derivatives to manage its exposure to changing interest rates, 
securities prices and currency exchange rates, or to increase its investment 
return. A derivative is a financial instrument the value of which is 
"derived" from the performance of an underlying asset (such as a security or 
index of securities). In addition to futures and options, derivatives include 
such instruments as forward contracts, swaps, structured notes, and 
collateralized mortgage obligations (CMOs). A forward contract is a purchase 
or sale of a specific quantity of a commodity, government security, foreign 
currency, or other financial instrument at the current price, with delivery 
and settlement at a specified future date. A swap is an exchange of one 
security for another and may be executed to exchange the maturities of a bond 
portfolio or the quality of the issues in a stock or bond portfolio. 
Structured notes are privately placed fixed income securities whose coupon 
and/or final payment depends on the return of a stock market index, portfolio 
or security. Further information about CMOs is contained in the SAI. Except 
for the purpose of hedging, the Fund may not invest more than 5% of its 
assets in derivatives which management deems to involve high risk to the 
Fund, such as inverse floaters, Interest Only and Principal Only Securities. 

Options and futures contracts can be volatile investments and involve certain 
risks. The Fund may be unable to limit losses by closing a position due to 
lack of a liquid market or similar factors. Losses may also occur if there is 
not a perfect correlation between the value of the contracts and the related 
securities. The use of futures may involve a high degree of leverage because 
of low margin requirements. As a result, small price movements in futures 
contracts may result in immediate and potentially unlimited gains or losses 
to the Fund. The amount of gains or losses on investments in futures 
contracts depends on the portfolio manager's ability to predict correctly the 
direction of stock prices, interest rates and other economic factors. Further 
information about the use of futures, options and other derivative 
instruments, and the associated risks, is contained in the SAI. 

High Risk High-Yield Securities  The Fund may invest up to 30% of its total 
assets in high risk high-yield securities, often called junk bonds. These 
securities are rated BB/Ba or below (securities with capacity to meet 
interest and principal payments but greater vulnerability to default), or, if 
unrated, considered by the Investment Adviser to be of comparable quality. 
The Fund will not invest in any debt security rated lower than B. High risk 
high-yield securities tend to offer higher yields than investment- grade 
bonds because of the additional risks associated with them. These risks 
include: a lack of liquidity; an unpredictable secondary market; a greater 
likelihood of default; increased sensitivity to difficult economic and 
corporate developments; call provisions which may adversely affect investment 
returns; and loss of the entire principal and interest.

International Securities  The Fund may invest up to 25% of its total assets 
in debt and/or equity international securities including depository receipts. 
Investments in securities of foreign issuers or securities denominated in 
foreign currencies involve risks not present in domestic markets. Such risks 
include: currency fluctuations and related currency conversion costs; less 
liquidity; price or income volatility; less government supervision and 
regulation of foreign stock exchanges, brokers and listed companies; possible 
difficulty in obtaining and enforcing judgments against foreign entities; 
adverse foreign political and economic developments; different accounting 
procedures and auditing standards; the possible imposition of withholding 
taxes on interest income payable on securities; the possible seizure or 
nationalization of foreign assets; the possible establishment of exchange 
controls or other foreign laws or restrictions which might adversely affect 
the payment and transferability of principal, interest and dividends on 
securities; higher transaction costs; possible settlement delays and less 
publicly available information about foreign issuers. 

Income Shares can invest in both sponsored and unsponsored depository 
receipts. Unsponsored depository receipts, which are typically traded in the 
over-the-counter market, may be less liquid than sponsored depository 
receipts and therefore may involve more risk. In addition, there may be less 
information available about issuers of unsponsored depository receipts. The 
Fund will generally acquire American Depository Receipts (ADRs) which are 
dollar denominated, although their market price is subject to fluctuations of 
the foreign currency in which the underlying securities are denominated. All 
depository receipts will be considered international securities for purposes 
of the Fund's investment limitation concerning investment in international 
securities. 

Mortgage-Backed Securities  The Fund may invest in mortgage-backed and other 
pass-through securities. Payments of interest and principal on these 
securities may be guaranteed by an agency or instrumentality of the U.S. 
Government such as the Government National Mortgage Association (GNMA), the 
Federal Home Loan Mortgage Corporation (FHLMC) and the Federal National 
Mortgage Association (FNMA). These securities represent part ownership of a 
pool of mortgage loans and principal is scheduled to be paid back by the 
borrower over the length of the loan rather than returned in a lump sum at 
maturity. The Fund may also invest in private pass-through securities backed 
by pools of conventional fixed-rate or adjustable-rate mortgage loans. In 
addition, the Fund may invest in collateralized mortgage obligations (CMOs) 
and securities issued by real estate mortgage investment conduits (REMICs). 
Mortgage-backed securities are also subject to the same prepayment risk as 
asset-backed securities. 

Repurchase Agreements  Under a repurchase agreement, the Fund may acquire a 
debt instrument for a relatively short period subject to an obligation by the 
seller to repurchase and by the Fund to resell the instrument at a fixed 
price and time. Assets may be invested in repurchase agreements with domestic 
banks and broker-dealers. Such agreements, although fully collateralized, 
involve the risk that the seller of the securities may fail to repurchase 
them. In that event, the Fund may incur costs in liquidating the collateral 
or a loss if the collateral declines in value. If the default on the part of 
the seller is due to insolvency and the seller initiates bankruptcy 
proceedings, the ability of the Fund to liquidate the collateral may be 
delayed or limited. 

The Fund's Board of Trustees has established credit standards for issuers of 
repurchase agreements entered into by the Fund. 

Securities Lending  The Fund may lend its portfolio securities; however, the 
value of the loaned securities (together with all other assets that are 
loaned, including those subject to repurchase agreements) may not exceed 
one-third of the Fund's total assets. The Fund will not lend portfolio 
securities to affiliates. Though fully collateralized, lending portfolio 
securities involves certain risks, including the possibility that the 
borrower may become insolvent or default on the loan. In the event of a 
disparity between the value of the loaned security and the collateral, there 
is the additional risk that the borrower may fail to return the securities or 
provide additional collateral. A loan may be terminated at any time by the 
borrower or lender upon proper notice. 

Income Shares is subject to further investment restrictions described in the 
SAI. 

                            MANAGEMENT OF THE FUND

                             GENERAL INFORMATION 

Declaration of Trust  Income Shares was organized as a "Massachusetts 
business trust" under the laws of Massachusetts on January 25, 1984. It began 
operations on May 1, 1984 upon succeeding to the assets of Aetna Income 
Shares, Inc. Massachusetts law provides that shareholders of the Fund can, 
under certain circumstances, be held personally liable for the obligations of 
the Fund. The Fund has been structured, and will be operated in such a way, 
so as to ensure as much as possible, that shareholders will not be liable for 
obligations of the Fund. The Declaration of Trust (Declaration) contains an 
express disclaimer of shareholder liability for acts or obligations of the 
Fund under Massachusetts law, and requires that notification of this 
disclaimer be given in each agreement, obligation or instrument entered into 
by the Fund or the Trustees. A more complete discussion of potential 
liability of shareholders of the Fund under Massachusetts law is contained in 
the SAI under "Description of Shares -- Shareholder and Trustee Liability." 

Capital Stock  The Declaration permits the Trustees to issue an unlimited 
number of full and fractional shares of beneficial interest in the Fund. All 
shares are nonassessable, other than as disclosed above. There are no 
preemptive rights. 

   
As of March 31, 1996, there were            shares of the Fund outstanding, 
99% of which were owned by ALIAC and held in its separate accounts to fund 
ALIAC's obligations under its variable annuity contracts and variable life 
insurance policies. An additional .2% of the Fund's shares were owned by an 
affiliate of ALIAC at that date. 

Maintenance Fee  Each shareholder account is charged an annual account 
maintenance fee which is redeemed from each shareholder account. The fee for 
1996 is $28.00 and the fee for 1997 will be $28.00. The 1996 annual account 
maintenance fee was collected on January 31, 1996. The 1997 annual account 
maintenance fee will be collected in January 1997. NOTE: This charge is not 
applicable to Variable Annuity contract or Variable Life Insurance policy 
holders and/or participants who select Aetna Income Shares as an investment 
funding option. 
    

Shareholder Inquiries and Distribution Options  Any questions about the Fund 
can be addressed to the Fund at the address listed on the cover of this 
Prospectus or by calling 1-800-367-7732. Shareholders may elect to receive 
dividends and capital gains distributions in cash or to reinvest in 
additional shares in the Fund. See "Fund Distributions" below for further 
information. 

Shareholder Meetings  The Fund is not required to hold annual shareholder 
meetings. The Declaration provides for meetings of shareholders to elect 
Trustees at such time as may be determined by the Trustees or as required by 
the Investment Company Act of 1940. If requested by the holders of at least 
10% of the Fund's outstanding shares, the Fund will hold a shareholder 
meeting for the purpose of voting on the removal of one or more Trustees and 
will assist with communications concerning that shareholder meeting. 

Voting Rights  Shareholders are entitled to one vote for each full share held 
and fractional votes for fractional shares held on matters submitted to the 
shareholders of the Fund. Voting rights are not cumulative. Participants who 
select the Fund for investment through their variable annuity contract or 
variable life insurance policy are not the shareholders of the Fund, but may 
have the right to direct the voting of Fund shares at shareholder meetings if 
required by law. 

                                 TAX MATTERS 

The following discussion of federal income tax consequences is based on tax 
laws and regulations in effect on the date of this prospectus, and is subject 
to change by legislative or administrative action. The following discussion 
is for general information only; a more detailed discussion of federal income 
tax consideration is contained in the SAI. The term "shareholders", as used 
below, refers to insurance company separate accounts who hold shares in 
connection with variable annuity or variable life insurance contracts, or 
other shareholders holding direct shares of the Fund. Holders of variable 
annuity contracts or variable life insurance policies should consult the 
prospectuses of their respective contracts or policies for information 
concerning federal income tax consequences.

The Fund  The Fund intends to qualify as a regulated investment company by 
satisfying the requirements under Subchapter M of the Internal Revenue Code 
of 1986, as amended (the "Code") concerning: (1) the diversification of 
assets; (2) the distribution of income; and (3) the source of income. It is 
the policy of the Fund to distribute to shareholders all of its investment 
income (net of expenses) and any capital gains (net of capital losses) in 
accordance with the timing requirements imposed by the Code. In addition, the 
Fund intends to comply with the variable asset diversification requirements 
under Section 817(h) of the Code, which are described more fully in the SAI. 

Fund Distributions  Distributions by the Fund of net long-term capital gains 
are taxable to shareholders as long-term capital gains regardless of the 
length of time a shareholder has held his shares. Distributions by the Fund 
of its net investment income and its net short-term capital gains are taxable 
to shareholders as ordinary income. Distributions paid by the Fund to the 
insurance company separate accounts and redemption of Fund shares held by the 
separate accounts will not result in taxable income to holders of variable 
annuity contracts and variable life insurance policies. 

In general, shareholders include distributions in their taxable income in the 
year in which they are received (whether paid in cash or reinvested). 
However, distributions declared in December and paid in January are taxable 
as if paid on December 31 of the year of declaration. A statement will be 
sent to shareholders indicating the tax status of all distributions made 
during the previous year. 

Share Redemptions  Any gain or loss recognized upon a taxable disposition of 
a shareholder's shares will be treated as a taxable long-term or short-term 
capital gain or loss (depending on whether the shareholder has held the 
shares more than 12 months). Any loss realized upon a taxable disposition of 
a Fund's shares may be subject to limitations that are described more fully 
in the SAI. 

Tax Withholding  In order to avoid backup withholding, shareholders must 
provide the Fund with a correct social security or taxpayer identification 
number and certify that the shareholder is a corporation or otherwise exempt 
from or not subject to backup withholding by the Internal Revenue Service 
(IRS). If a shareholder is subject to backup withholding, the IRS can require 
the Fund to withhold 31% of taxable dividends, capital gains distributions 
and redemptions. 

                        SALE AND REDEMPTION OF SHARES 

ALIAC is the principal underwriter of the Fund pursuant to a Distribution 
Agreement between it and the Fund. Shares may only be purchased by ALIAC as 
the Depositor of Variable Annuity and Variable Life Separate Accounts as 
directed by Participants. 

Shares of the Fund are sold and redeemed at their net asset value next 
determined after receipt of a purchase or redemption order in acceptable 
form. Shareholders must provide a signature guarantee regardless of the 
redemption amount. No sales charge or redemption charge is made. 

Certain individuals own direct interests in the Fund. If those shareholders 
have less than a $1,000 balance in their Account, their shares may be 
liquidated upon six months' notice. 

If such a shareholder holds Fund shares having a net asset value of $5,000 or 
more, he or she may establish a Systematic Withdrawal Program. Further 
information about this program may be obtained from the Fund. 

                               NET ASSET VALUE 

The net asset value per share (NAV) of the Fund is determined as of 4:15 p.m. 
Eastern time on each day that the New York Stock Exchange is open for 
trading. The NAV is computed by dividing the total value of the Fund's 
securities, plus any cash or other assets less all liabilities (including 
accrued expenses), by the number of shares outstanding. 

Portfolio securities are valued at their market price, at the mean of the 
last bid and asked price or amortized to maturity. All other assets, 
including restricted securities and other securities for which market 
quotations are not readily available, are valued at their fair value in such 
manner as may be determined, from time to time, in good faith by, or under 
the authority of, the Trustees. The Trustees may authorize the use of 
independent pricing services, where appropriate.

                                    APPENDIX
                    DESCRIPTION OF CORPORATE BOND RATINGS 
                       Moody's Investors Service, Inc. 

"Aaa" Rating 
Bonds which are rated Aaa are judged to be of the best quality and carry the 
smallest degree of investment risk. 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" Rating 
Bonds which are rated Aa are judged to be of high quality by all standards. 
Together with the Aaa group they 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 greater than in Aaa securities. 

"A" Rating 
Bonds which are rated A possess many favorable investment attributes and are 
considered upper-medium-grade obligations. Factors relating to security of 
principal and interest are considered adequate but elements may be present 
which suggest possible impairment sometime in the future. 

"Baa" Rating 
Bonds which are rated Baa are considered 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 have speculative characteristics. 

"Ba" Rating 
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 this class of bond. 

"B" Rating 
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. 

The modifier 1 indicates that the bond ranks in the higher end of its generic 
rating category; the modifier 2 indicates a mid-range ranking; and the 
modifier 3 indicates that the issue ranks in the lower end of its rating 
category. 

                        Standard & Poor's Corporation 

"AAA" Rating 
Bonds which are rated AAA have the highest rating assigned by Standard & 
Poor's. Capacity to pay interest and repay principal is extremely strong. 

"AA" Rating 
Bonds which are rated AA have a very strong capacity to pay interest and 
repay principal and differ from the highest rated issues only in small 
degree. 

"A" Rating 
Bonds which are rated A have a strong capacity to pay interest and repay 
principal although they are somewhat more susceptible to the adverse effects 
of changes in circumstances and economic conditions than debt in higher rated 
categories. 

"BBB" Rating 
Bonds which are rated BBB are regarded as having an adequate capacity to pay 
interest and repay principal. Whereas it normally exhibits adequate 
protection, 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. 

"BB" Rating 
Bonds which are rated BB have less near-term vulnerability to default than 
other speculative issues. However, the bonds face major uncertainties or 
exposure to adverse business, financial, or economic conditions which could 
lead to inadequate capacity to meet timely interest and principal payments. 

"B" Rating 
Bonds which are rated B have a greater vulnerability to default but currently 
have the capacity to meet interest payments and principal repayments. Adverse 
business, financial, or economic conditions will likely impair capacity or 
willingness to pay interest and repay principal. 

The ratings from "AA" to "B" may be modified by the addition of a plus (+) or 
minus (-) sign to show relative standing within the major rating categories.

GENERAL INFORMATION AND HISTORY 

Aetna Income Shares ("Income Shares" or "Fund") is an open-end diversified 
management investment company which sells its shares of beneficial interest 
to (i) Aetna Life Insurance and Annuity Company ("Company") for allocation to 
certain of its separate accounts, each of which has been established for the 
purpose of funding either variable annuity contracts or variable life 
insurance contracts issued by the Company, (ii) affiliates and subsidiaries 
of the Company for allocation to their separate accounts in connection with 
the purchase of annuity contracts and (iii) other shareholders of the Fund 
only through reinvestment of dividends. 

                INVESTMENT OBJECTIVE AND POLICIES OF THE FUND 

The investment objective of Income Shares is to maximize total return, 
consistent with reasonable risk, through investments in a diversified 
portfolio consisting primarily of debt securities. The Fund defines 
reasonable risk as the degree of risk of loss that an average investor would, 
in light of the fund's investment policies, be willing to tolerate in seeking 
to maximize total return. It is anticipated that capital appreciation and 
investment income will both be major factors in achieving such a return. The 
Fund's investment adviser may, to a limited extent, cause the Fund to 
purchase debt securities which have equity features; preferred or common 
stock, (the latter principally for their income potential through dividends 
and option writing); or may acquire securities having a mix of these 
characteristics. 

Income shares will operate under the following restrictions, which together 
with its investment objective, are matters of fundamental policy and cannot 
be changed without the approval of a majority of the outstanding voting 
securities of the Fund. This means the lesser of: (i) 67% of the shares of 
the Fund present or represented at a shareholders' meeting if the holders of 
more than 50% of the shares then outstanding are present or represented; or 
(ii) more than 50% of the outstanding voting securities of the Fund. 

In pursuing its investment objective, Income Shares will not: 

 (1) issue any senior security, as defined in the Investment Company Act of 
     1940 (the "1940 Act"), except that (a) the Fund may enter into 
     commitments to purchase securities in accordance with the Fund's 
     investment program, including reverse repurchase agreements, 
     delayed-delivery and when-issued securities, which may be considered the 
     issuance of senior securities, (b) the Fund may engage in transactions 
     that may result in the issuance of a senior security to the extent 
     permitted under applicable regulations, interpretations of the 1940 Act 
     or an exemptive order; (c) the Fund may engage in short sales of 
     securities to the extent permitted in its investment program and other 
     restrictions; (d) the purchase or sale of futures contracts and related 
     options shall not be considered to involve the issuance of senior 
     securities; and (e) subject to fundamental restrictions, the Fund may 
     borrow money as authorized by the 1940 Act; 

 (2) hold more than 5% of the value of its total assets in the securities of 
     any one issuer or hold more than 10% of the outstanding voting 
     securities of any one issuer. This restriction applies only to 75% of 
     the value of the Fund's total assets. Securities issued or guaranteed by 
     the U.S. Government, its agencies and instrumentalities are excluded 
     from this restriction; 

 (3) concentrate its investments in any one industry except that the Fund may 
     invest up to 25% of its total assets in securities issued by companies 
     principally engaged in any one industry. This limitation will not, 
     however, apply to securities issued or guaranteed by the U.S. 
     Government, its agencies and instrumentalities; 

 (4) make loans, except that, to the extent appropriate under its investment 
     program, the Fund may (a) purchase bonds, debentures or other debt 
     securities, including short-term obligations, (b) enter into repurchase 
     transactions and (c) lend portfolio securities provided that the value 
     of such loaned securities does not exceed one-third of the Fund's total 
     assets; 

 (5) invest in commodity contracts, except that the Fund may, to the extent 
     appropriate under its investment program, purchase securities of 
     companies engaged in such activities, may enter into trans- 

2 Aetna Income Shares 
<PAGE>
 
     actions in financial and index futures contracts and related options, 
     may engage in transactions on a when-issued or forward commitment basis, 
     and may enter into forward currency contracts; 

 (6) borrow money, except that (a) the Fund may enter into certain futures 
     contracts and options related thereto; (b) the Fund may enter into 
     commitments to purchase securities in accordance with the Fund's 
     investment program, including delayed-delivery and when-issued 
     securities and reverse repurchase agreements; (c) for temporary 
     emergency purposes, the Fund may borrow money in amounts not exceeding 
     5% of the value of its total assets at the time the loan is made; and 
     (d) for purposes of leveraging, the Fund may borrow money from banks 
     (including its custodian bank) only if, immediately after such 
     borrowing, the value of the Fund's assets, including the amount 
     borrowed, less its liabilities, is equal to at least 300% of the amount 
     borrowed, plus all outstanding borrowings. If, at any time, the value of 
     the Fund's assets fails to meet the 300% asset coverage requirement 
     relative only to leveraging, the Fund will, within three days (not 
     including Sundays and holidays), reduce its borrowings to the extent 
     necessary to meet the 300% test; 

 (7) purchase real estate, interests in real estate or real estate limited 
     partnership interests except that, to the extent appropriate under its 
     investment program, the Fund may invest in securities secured by real 
     estate or interests therein or issued by companies, including real 
     estate investment trusts, which deal in real estate or interests 
     therein; or 

 (8) act as an underwriter of securities except to the extent that, in 
     connection with the disposition of portfolio securities by the Fund, the 
     Fund may be deemed to be an underwriter under the provisions of the 
     Securities Act of 1933, as amended (the "1933 Act"). 

The Fund has also adopted certain other investment restrictions which may be 
changed by the Fund's Trustees and without shareholder vote. Under such 
restrictions, the Fund will not: 

 (1) invest more than 15% of its total assets in illiquid securities. 
     Illiquid securities are securities that are not readily marketable or 
     cannot be disposed of promptly within seven days and in the usual course 
     of business without taking a materially reduced price. Such securities 
     include, but are not limited to, time deposits and repurchase agreements 
     with maturities longer than seven days. Securities that may be resold 
     under Rule 144A or securities offered pursuant to Section 4(2) of the 
     1933 Act, as amended, shall not be deemed illiquid solely by reason of 
     being unregistered. The Investment Adviser shall determine whether a 
     particular security is deemed to be liquid based on the trading markets 
     for the specific security and other factors; 

 (2) invest in companies for the purpose of exercising control or management; 

 (3) purchase the securities of any other investment company, except as 
     permitted under the 1940 Act; or 

 (4) make short sales of securities, other than short sales "against the 
     box," or purchase securities on margin except for short-term credits 
     necessary for clearance of portfolio transactions, provided that this 
     restriction will not be applied to limit the use of options, futures 
     contracts and related options, in the manner otherwise permitted by the 
     investment restrictions, policies and investment program of the Fund. 

Where the Fund's investment objective or policy restricts it to a specified 
percentage of its total assets in any type of instrument, that percentage is 
measured at the time of purchase. There will be no violation of any 
investment policy or restriction if that restriction is complied with at the 
time the relevant action is taken notwithstanding a later change in the 
market value of an investment, in net or total assets, in the securities 
rating of the investment or any other change. 

         DESCRIPTION OF VARIOUS SECURITIES AND INVESTMENT TECHNIQUES 

The following information supplements and should be read in conjunction with 
the section of the prospectus entitled "Investment Policies and 
Restrictions." 

                                                         Aetna Income Shares 3 
<PAGE>
 
U.S. Government Obligations 
The types of U.S. Government obligations in which Income Shares may invest 
include, but are not limited to: (1) direct obligations of the U.S. Treasury, 
such as U.S. Treasury bonds, notes, bills and Treasury Certificates of 
Indebtedness; (2) instruments issued or guaranteed by U.S. Government 
agencies or instrumentalities which are backed by (a) the full faith and 
credit of the United States, (b) the credit of the agency or instrumentality 
issuing the obligations, or (c) the right of the issuer to borrow from the 
U.S. Treasury, such as notes, bonds, and discount notes of U.S. Government 
instrumentalities or agencies, including Federal Land Banks, Central Bank for 
Cooperatives, Federal Intermediate Credit Banks, Federal Home Loan Banks, 
Farmers Home Administration and Federal National Mortgage Association. (A 
U.S. Government instrumentality is a government agency organized under 
federal charter with government supervision.) 

Repurchase Agreements 
Income Shares may enter into repurchase agreements with domestic banks and 
broker-dealers meeting certain size and creditworthiness standards 
established by the Fund's Board of Trustees. Under a repurchase agreement, 
the Fund may acquire a debt instrument for a relatively short period (usually 
not more than one week) subject to an obligation of the seller to repurchase 
and the Fund to resell the instrument at a fixed price and time, thereby 
determining the yield during the Fund's holding period. This results in a 
fixed rate of return insulated from market fluctuations during such period. 
Such underlying debt instruments serving as collateral will meet the quality 
standards of the Fund. The market value of the underlying debt instruments 
will, at all times, be equal to the dollar amount invested. Under the 1940 
Act, repurchase agreements are considered loans by the Fund. Repurchase 
agreements, although fully collateralized, involve the risk that the seller 
of the securities may fail to repurchase them from the Fund. In that event, 
the Fund may incur (a) disposition costs in connection with liquidating the 
collateral, or (b) a loss if the collateral declines in value. Also, if the 
default on the part of the seller is due to insolvency and the seller 
initiates bankruptcy proceedings, the Fund's ability to liquidate the 
collateral may be delayed or limited. Repurchase agreements maturing in more 
than seven days will not exceed 15 percent of the total assets of the Fund. 
The Fund does not intend to use reverse repurchase agreements. 

Securities Lending 
Income Shares may lend up to one-third of its total assets, although it is 
anticipated that less than 10% of such assets will be on loan at any one 
time. In the Company's opinion, lending portfolio securities to qualified 
broker-dealers affords the Fund a means of increasing the yield on its 
portfolio. All such loans will be fully collateralized with either cash or 
direct obligations of the U.S. Government or agencies thereof. The Fund will 
be entitled either to receive a fee from the borrower or to retain some or 
all of the income derived from its investment of cash collateral. The Fund 
will continue to receive the interest or dividends paid on any securities 
loaned, or amounts equivalent thereto. Although voting rights will pass to 
the borrower of securities, whenever a material event affecting the borrowed 
securities is to be voted on, the Fund may terminate the loan to vote such 
proxy. 

The primary risk the Fund assumes in loaning securities is that the borrower 
may become insolvent on a day on which the loaned security is rapidly 
increasing in price. In such event, if the borrower fails to return the 
loaned securities, the existing collateral might be insufficient to purchase 
back the full amount of security loaned, and the borrower would be unable to 
furnish additional collateral. The borrower would be liable for any shortage, 
but the Fund would be an unsecured creditor as to such shortage and might not 
be able to recover all or any part of it. A loan may be terminated at any 
time by the borrower or lender upon proper notice. 

Foreign Securities 
The Fund may invest up to 25% of its total assets in foreign securities. 
These securities will be marketable equity securities (including common and 
preferred stock, depository receipts for stock and fixed income or equity 
securities exchangeable for or convertible into stock) and debt securities of 
foreign companies which generally are listed on recognized foreign securities 
exchanges or are traded in a foreign over- the-counter market. The Fund also 
invests in foreign securities listed on recognized U.S. securities 

4 Aetna Income Shares 
<PAGE>
 
exchanges or traded in the U.S. over-the-counter market. Such foreign 
securities may be issued by foreign companies located in developing countries 
in various regions of the world. A "developing country" is a country in the 
initial stages of its industrial cycle. As compared to investment in the 
securities markets of developed countries, investment in the securities 
markets of developing countries involves exposure to markets that may have 
substantially less trading volume and greater price volatility, economic 
structures that are less diverse and mature, and political systems that may 
be less stable. 

Depository receipts are typically dollar denominated, although their market 
price is subject to fluctuations of the foreign currency in which the 
underlying securities are denominated. Depository receipts include: (1) 
American Depository Receipts (ADRs), which are typically designed for U.S. 
investors and held either in physical form or in book entry form; (2) 
European Depository Receipts (EDRs), which are similar to ADRs but may be 
listed and traded on a European exchange as well as in the U.S. Typically, 
these securities are traded on the Luxembourg exchange in Europe; and (3) 
Global Depository Receipts (GDRs), which are similar to EDRs although they 
may be held through foreign clearing agents such as Euroclear and other 
foreign depositories. All depository receipts will be considered foreign 
securities for purposes of a Fund's investment limitation concerning 
investment in foreign securities. 

Investments in securities of foreign issuers involve certain risks not 
associated with investments in securities of domestic issuers. These risks 
include the following: 

Currency Risk--The value of the Fund's foreign investments will be effected 
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 Fund may invest are not as developed as the U.S. economy and may be 
subject to significantly different forces. Political or social instability, 
expropriation or confiscatory taxation and limitation upon the removal of 
funds or other assets could adversely affect the value of the Fund's 
investments. 

Regulatory Risk--Foreign companies are not registered with the Securities and 
Exchange Commission (the "SEC") and are generally not subject to the 
regulatory controls imposed on United States issuers and, as a consequence, 
there is generally less publicly available information about foreign 
securities than is available regarding domestic securities. Foreign companies 
are not subject to uniform accounting, auditing and financial standards, 
practices and requirements comparable to those applicable to U.S. companies. 
Income from foreign securities owned by the Fund may be subject to 
withholding taxes imposed at the source which would reduce dividend income 
payable to the Fund's shareholders. 

Market Risk--The securities markets in many of the countries in which the 
Fund may invest have substantially less trading volume than the major U.S. 
markets. Consequently, the securities of some foreign issuers may be less 
liquid and experience more price volatility than comparable domestic 
securities. Indeed, custodian costs, as well as administrative costs (such as 
the need to use foreign custodians) 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 commission rates in foreign jurisdictions are 
likely to be higher than in the United States. 

Interest Rate Futures Contracts and Options on Such Contracts 
An interest rate futures contract provides for the future sale by one party 
and purchase by another party of a specified amount of a specified financial 
instrument (debt security) or index for a specified price at a designated 
date, time and place. Income Shares may enter into interest rate futures 
contracts as a hedge against changes in prevailing levels of interest rates, 
or in order to establish more definitely the effective return on securities 
held or intended to be acquired by the Fund. The Fund's hedging may include 
sales of futures as an offset against the effect of expected increases in 
interest rates. 

                                                         Aetna Income Shares 5 
<PAGE>
 
Although techniques other than sales and purchases of futures contracts could 
be used to reduce the exposure of the Fund to market fluctuations, the Fund 
may be able to hedge its exposure more effectively and perhaps at a lower 
cost through using futures contracts. The Fund will not enter into a futures 
contract if, as a result thereof, (i) the then current aggregate futures 
market prices of financial instruments required to be delivered and purchased 
under open futures contracts would exceed 30% of the Fund's total assets, 
(taken at market value at the time of entering into the Contract), or (ii) 
more than 5% of the Fund's total assets (taken at market value at the time of 
entering into the Contract), would be committed to margin deposits on such 
futures contracts. 

Although interest rate futures contracts typically require actual future 
delivery of and payment for the underlying instruments, the contracts are 
usually closed out before the delivery date. Closing out an open futures 
contract sale or purchase is effected by entering into an offsetting futures 
contract purchase or sale, respectively, for the same aggregate amount of the 
identical type of underlying instrument and the same delivery date. There can 
be no assurance, however, that the Fund will be able to enter into an 
offsetting transaction with respect to a particular contract at a particular 
time. If the Fund is not able to enter into an offsetting transaction, the 
Fund will continue to be required to maintain the margin deposits on the 
contract. 

Persons who engage in futures contracts transactions may be broadly 
classified as "hedgers" and "speculators." Hedgers, such as the Fund, whose 
business activity involves investment in securities, use the futures markets 
primarily to offset unfavorable changes in value that may occur because of 
fluctuations in the value of the securities held or expected to be acquired 
by them. Debtors and other obligors may also hedge the interest cost of their 
obligations. The speculator, like the hedger, generally expects neither to 
deliver nor to receive the financial instrument underlying the futures 
contract, but, unlike the hedger, hopes to profit from fluctuations in 
prevailing equities prices. 

The Fund will not enter into financial futures contracts for speculation, and 
will only enter into futures contracts that are traded on national futures 
exchanges and are standardized as to maturity date and underlying financial 
instrument. Futures exchanges and trading are regulated under the Commodity 
Exchange Act by the Commodity Futures Trading Commission ("CFTC"). 

"Margin" is the amount of funds that must be deposited by Income Shares with 
a commodities broker in a custodian account in order to initiate futures 
trading and to maintain open positions in the Fund's futures contracts. A 
margin deposit is intended to assure the Fund's performance of the futures 
contract. The margin required for a particular futures contract is set by the 
exchange on which the contract is traded and may be significantly modified 
from time to time by the exchange during the term of the contract. If the 
price of an open futures contract changes (by increase in the case of a sale 
or by decrease in the case of a purchase) so that the loss on the futures 
contract reaches a point at which the margin on deposit does not satisfy 
margin requirements, the broker will require an increase in the margin. 
However, if the value of a position increases because of favorable price 
changes in the futures contract so that the margin deposit exceeds the 
required margin, the broker will promptly pay the excess to the Fund. These 
daily payments to and from the Fund are called variation margin. At times of 
extreme price volatility such as occurred during the week of October 19, 
1987, intra-day variation margin payments may be required. In computing daily 
net asset values, Income Shares will mark to market the current value of its 
open futures contracts. Income Shares expects to earn interest income on its 
initial margin deposits. 

Because of the low margin deposits required, futures trading involves an 
extremely high degree of leverage. As a result, small price movements in 
futures contracts may result in immediate and potentially unlimited loss or 
gain to the Fund relative to the size of the margin commitment. For example, 
if at the time of purchase 10% of the value of the futures contract is 
deposited as margin, a subsequent 10% decrease in the value of the futures 
contract would result in a total loss of the margin deposit before any 
deduction for the transaction costs, if the contract were then closed out. A 
15% decrease in the value of the futures contract would result in a loss 
equal to 150% of the original margin deposit, if the contract were closed 
out. Thus, a purchase or sale of a futures contract may result in losses in 
excess of the amount initially 

6 Aetna Income Shares 
<PAGE>
 
invested in the futures contract. However, the Fund would presumably have 
sustained comparable losses if, instead of the futures contract, it had 
invested in the underlying financial instrument and sold it after the 
decline. Furthermore, in the case of a futures contract purchase, the Fund 
deposits in a segregated account money market instruments sufficient to meet 
all futures contract initial margin requirements. 

Restrictions on the Use of Futures and Option Contracts 
CFTC regulations require that all short futures positions be entered into for 
the purpose of hedging the value of securities held in the Fund's portfolio, 
and that all long futures positions either constitute bona fide hedging 
transactions, as defined in such regulations, or have a total value not in 
excess of an amount determined by reference to certain cash and securities 
positions maintained for the Fund, and accrued profits on such positions. 

The Fund's ability to engage in the hedging transactions described herein may 
be limited by the current federal income tax requirement that a Fund derive 
less than 30% of its gross income from the sale or other disposition of stock 
or securities held for less than three months. 

Covered Call and Put Options on Securities 
The Fund may write (sell) covered call options ("call options") and purchase 
covered put options ("put options") on securities and indexes, and purchase 
call and sell put options to close out positions previously opened by the 
Fund, provided, however, that it will not have call options outstanding at 
any one time on more than 30% of its total assets nor will it buy put options 
if more than 3% of the assets of the Fund immediately following such purchase 
would consist of put options. The purpose of writing call options and 
purchasing put options will be to reduce the effect of price fluctuations of 
the securities owned by the Fund (and involved in the options) on the net 
asset value per share of the Fund. 

A call option gives the holder (buyer) the right to purchase a security at a 
specified price (the exercise price) at any time until a certain date (the 
expiration date). So long as the obligation of the writer of a call option 
continues, he may be assigned an exercise notice by the broker-dealer through 
whom such option was settled, requiring him to deliver the underlying 
security against payment of the exercise price. This obligation terminates 
upon the expiration of the call option, the exercise of the call option, or 
by entering into an offsetting transaction. To secure his obligation to 
deliver the underlying security in the case of a call option, a writer is 
required to deposit in escrow the underlying security or other assets in 
accordance with the rules of the clearing corporations and of the exchanges. 
A put option gives the holder (buyer) the right to sell a security at a 
specified price (the exercise price) at any time until a certain date (the 
expiration date). Income Shares will only write a call option or purchase a 
put option on a security which it already owns and will not write call 
options on when-issued securities. The Fund may purchase a put option on a 
security that it already owns and on stock indexes. 

The Fund will write call options and purchase put options in standard 
contracts listed on national securities exchanges, or write call options with 
and purchase put options directly from investment dealers meeting the 
creditworthiness criteria of the Company. 

When writing a call option, the Fund, in return for the premium, gives up the 
opportunity to profit from a price increase in the underlying security above 
the exercise price, but conversely retains the risk of loss should the price 
of the security decline. If a call option which the Fund has written expires, 
the Fund will realize a gain in the amount of the premium; however, such gain 
may be offset by a decline in the market value of the underlying security 
during the option period. If the call option is exercised, the Fund will 
realize a gain or loss from the sale of the underlying security. The Fund 
will purchase put options involving portfolio securities only when the 
Company believes that a temporary defensive position is desirable in light of 
market conditions, but does not desire to sell the portfolio security. 
Therefore, the purchase of put options will be used to protect the Fund's 
holdings in an underlying security against a substantial decline in market 
value. Such protection is, of course, only provided during the life of the 
put option when the Fund, as the holder of the put option, is able to sell 
the underlying security at the put exercise price regardless of any decline 
in the underlying security's market price. By using put options in this 
manner, the Fund 

                                                         Aetna Income Shares 7

will reduce any profit it might otherwise have realized in its underlying 
security by the premium paid for the put option and by transaction costs. The 
security covering the call or put option will be maintained in a segregated 
account of the Fund's custodian. 

The premium the Fund will receive from writing a call option, or the Fund 
will pay when purchasing a put option, will reflect, among other things, the 
current market price of the underlying security, the relationship of the 
exercise price to such market price, the historical price volatility of the 
underlying security, the length of the option period, and the general 
interest rate environment. The premium received by the Fund for writing 
covered call options will be recorded as a liability in the statement of 
assets and liabilities of the Fund. This liability will be adjusted daily to 
the option's current market value. The liability will be extinguished upon 
expiration of the option, by the exercise of the option, or by entering into 
an offsetting transaction. Similarly, the premium paid by the Fund when 
purchasing a put option will be recorded as an asset in the statement of 
assets and liabilities of the Fund. This asset will be adjusted daily to the 
option's current market value. The asset will be extinguished upon expiration 
of the option, by selling of an identical option in a closing transaction, or 
exercising the option. 

When writing put options on securities, to secure its obligation to pay for 
the underlying security, the Fund will deposit in escrow liquid assets with a 
value equal to or greater than the exercise price of the put option. The Fund 
therefore foregoes the opportunity of investing the segregated assets or 
writing calls against those assets. As long as the obligation of the Fund as 
the put writer continues, it may be assigned an exercise notice by the 
broker-dealer through whom such option was sold, requiring the fund to take 
delivery of the underlying security against payment of the exercise price. 
The Fund has no control over when it may be required to purchase the 
underlying security, since it may be assigned an exercise notice at any time 
prior to the termination of its obligation as the writer of the put. This 
obligation terminates upon expiration of the put, or such earlier time at 
which the Fund effects a closing purchase transaction by purchasing a put of 
the same series as that previously sold. 

Closing transactions will be effected in order to realize a profit on an 
outstanding call or put option, to prevent an underlying security from being 
called or put, or to permit the exchange or tender of the underlying 
security. Furthermore, effecting a closing transaction will permit the Fund 
to write another call option, or purchase another put option, on the 
underlying security with either a different exercise price or expiration date 
or both. If the Fund desires to sell a particular security from its portfolio 
on which it has written a call option, or purchased a put option, it will 
seek to effect a closing transaction prior to, or concurrently with, the sale 
of the security. There is, of course, no assurance that the Fund will be able 
to effect such closing transactions at a favorable price. If the Fund cannot 
enter into such a transaction, it may be required to hold a security that it 
might otherwise have sold, in which case it would continue to be at market 
risk on the security. The Fund will pay brokerage commissions in connection 
with the sale or purchase of options to close out previously established 
option positions. Such brokerage commissions are normally higher as a 
percentage of underlying asset values than those applicable to purchases and 
sales of portfolio securities. 

The exercise price of the options may be below, equal to, or above the 
current market values of the underlying securities at the time the options 
are written. From time to time, the Fund may purchase an underlying security 
for delivery in accordance with an exercise notice of a call option assigned 
to it, rather than delivering such security from its portfolio. In such cases 
additional brokerage commissions will be incurred. The Fund will realize a 
profit or loss from a closing purchase transaction if the cost of the 
transaction is less or more than the premium received from the writing of the 
call option; however, any loss so incurred in a closing purchase transaction 
may be partially or entirely offset by the premium received from a 
simultaneous or subsequent sale of a different call or put option. Also, 
because increases in the market price of a call option will generally reflect 
increases in the market price of the underlying security, any loss resulting 
from the repurchase of a call option is likely to be offset in whole or in 
part by appreciation of the underlying security owned by the Fund. 

Additional Risk Factors 
In addition to any risk factors which may be described above, the following 
sets forth certain information regarding the potential risks associated with 
the Fund's futures and options transactions. 

8 Aetna Income Shares 
<PAGE>
 
Risk of Imperfect Correlation--The Fund's ability to hedge effectively all or 
a portion of its portfolio through transactions in futures, options on 
futures or options on securities and indexes depends on the degree to which 
movements in the value of the securities or index underlying such hedging 
instrument correlate with movements in the value of the relevant portion of 
the Fund's portfolio. If the values of the portfolio securities being hedged 
do not move in the same amount or direction as the underlying security or 
index, the hedging strategy for the Fund might not be successful and the Fund 
could sustain losses on its hedging transactions which would not be offset by 
gains on its portfolio. It is also possible that there may be a negative 
correlation between the security or index underlying a futures or option 
contract and the portfolio securities being hedged, which could result in 
losses both on the hedging transaction and the portfolio securities. In such 
instances, the Fund's overall return could be less than if the hedging 
transactions had not been undertaken. Stock index futures or options based on 
a narrower index of securities may present greater risk than options or 
futures based on a broad market index, as a narrower index is more 
susceptible to rapid and extreme fluctuations resulting from changes in the 
value of a small number of securities. The Fund would, however, effect 
transactions in such futures or options only for hedging purposes (or to 
close out open positions). 

The trading of futures and options on indexes involves the additional risk of 
imperfect correlation between movements in the futures or option price and 
the value of the underlying index. The anticipated spread between the prices 
may be distorted due to differences in the nature of the markets, such as 
differences in margin requirements, the liquidity of such markets and the 
participation of speculators in the futures and options market. The purchase 
of an option on a futures contract also involves the risk that changes in the 
value of underlying futures contract will not be fully reflected in the value 
of the option purchased. The risk of imperfect correlation, however, 
generally tends to diminish as the maturity date of the futures contract or 
termination date of the option approaches. The risk incurred in purchasing an 
option on a futures contract is limited to the amount of the premium plus 
related transaction costs, although it may be necessary under certain 
circumstances to exercise the option and enter into the underlying futures 
contract in order to realize a profit. Under certain extreme market 
conditions, it is possible that the Fund will not be able to establish 
hedging positions, or that any hedging strategy adopted will be insufficient 
to completely protect the Fund. 

The Fund will purchase or sell futures contracts or options only if, in the 
Company's judgment, there is expected to be a sufficient degree of 
correlation between movements in the value of such instruments and changes in 
the value of the relevant portion of the Fund's portfolio for the hedge to be 
effective. There can be no assurance that the Company's judgment will be 
accurate. 

Potential Lack of a Liquid Secondary Market--The ordinary spreads between 
prices in the cash and futures markets, due to differences in the natures of 
those markets, are subject to distortions. First, all participants in the 
futures market are subject to initial deposit and variation margin 
requirements. This could require the Fund to post additional cash or cash 
equivalents as the value of the position fluctuates. Further, rather than 
meeting additional variation margin requirements, investors may close futures 
contracts through offsetting transactions which could distort the normal 
relationship between the cash and futures markets. Second, the liquidity of 
the futures or options market may be lacking. Prior to exercise or 
expiration, a futures or option position may be terminated only by entering 
into a closing purchase or sale transaction, which requires a secondary 
market on the exchange on which the position was originally established. 
While the Fund will establish a futures or option position only if there 
appears to be a liquid secondary market therefor, there can be no assurance 
that such a market will exist for any particular futures or option contract 
at any specific time. In such event, it may not be possible to close out a 
position held by the Fund, which could require the Fund to purchase or sell 
the instrument underlying the position, make or receive a cash settlement, or 
meet ongoing variation margin requirements. The inability to close out 
futures or option positions also could have an adverse impact on the Fund's 
ability effectively to hedge its portfolio, or the relevant portion thereof. 

The liquidity of a secondary market in a futures contract or an option on a 
futures contract may be adversely affected by "daily price fluctuation 
limits" established by the exchanges, which limit the amount 

                                                         Aetna Income Shares 9 
<PAGE>
 
of fluctuation in the price of a contract during a single trading day and 
prohibit trading beyond such limits once they have been reached. The trading 
of futures and options contracts also is subject to the risk of trading 
halts, suspensions, exchange or clearing house equipment failures, government 
intervention, insolvency of the brokerage firm or clearing house or other 
disruptions of normal trading activity, which could at times make it 
difficult or impossible to liquidate existing positions or to recover excess 
variation margin payments. 

Risk of Predicting Interest Rate Movements--Investments in futures contracts 
on fixed income securities and related indexes involve the risk that if the 
Company's investment judgment concerning the general direction of interest 
rates is incorrect, the Fund's overall performance may be poorer than if it 
had not entered into any such contract. For example, if the Fund has been 
hedged against the possibility of an increase in interest rates which would 
adversely affect the price of bonds held in its portfolio and interest rates 
decrease instead, the Fund will lose part or all of the benefit of the 
increased value of its bonds which have been hedged because it will have 
offsetting losses in its futures positions. In addition, in such situations, 
if the Fund has insufficient cash, it may have to sell bonds from its 
portfolio to meet daily variation margin requirements, possibly at a time 
when it may be disadvantageous to do so. Such sale of bonds may be, but will 
not necessarily be, at increased prices which reflect the rising market. 

Trading and Position Limits--Each contract market on which futures and option 
contracts are traded has established a number of limitations governing the 
maximum number of positions which may be held by a trader, whether acting 
alone or in concert with others. The Company does not believe that these 
trading and position limits will have an adverse impact on the hedging 
strategies regarding the Fund's portfolio. 

Mortgage-Related Debt Securities 
Federal mortgage-related securities include obligations issued or guaranteed 
by the Government National Mortgage Association ("GNMA"), the Federal 
National Mortgage Association ("FNMA") and the Federal Home Loan Mortgage 
Corporation ("FHLMC"). GNMA is a wholly owned corporate instrumentality of 
the United States whose securities and guarantees are backed by the full 
faith and credit of the United States. FNMA, a federally chartered and 
privately owned corporation, and FHLMC, a federal corporation, are 
instrumentalities of the United States, with Presidentially-appointed board 
members. The obligations of FNMA and FHLMC are not explicitly guaranteed by 
the full faith and credit of the federal government. 

Pass-through mortgage-related securities are characterized by monthly 
payments to the holder, reflecting the monthly payments made by the borrowers 
who received the underlying mortgage loans. The payments to the 
security-holders like the payments on the underlying loans, represent both 
principal and interest. Although the underlying mortgage loans are for 
specified periods of time, often twenty or thirty years, the borrowers can, 
and typically do, repay such loans sooner. Thus, the security holders 
frequently receive repayments of principal, in addition to the principal 
which is part of the regular monthly payment. A borrower is more likely to 
repay a mortgage which bears a relatively high rate of interest. This means 
that in times of declining interest rates, some higher yielding securities 
held by the Fund might be converted to cash, and the Fund could be expected 
to reinvest such cash at the then prevailing lower rates. The increased 
likelihood of prepayment when interest rates decline also limits market price 
appreciation of mortgage-related securities. If the Fund buys 
mortgage-related securities at a premium, mortgage foreclosures or mortgage 
prepayments may result in losses of up to the amount of the premium paid 
since only timely payment of principal and interest is guaranteed. 

As noted in the Prospectus, Income Shares may also invest in collateralized 
mortgage obligations ("CMOs") and real estate mortgage investment conduits 
("REMICs"). CMOs and REMICs are securities which are collateralized by 
mortgage pass-through securities. Cash flows from underlying mortgages are 
allocated to various classes or tranches in a predetermined, specified order. 
Each sequential tranche has a "stated maturity"--the latest date by which the 
tranche can be completely repaid, assuming no repayments--and has an "average 
life"--the average time to receipt of a principal payment weighted by 

10 Aetna Income Shares 
<PAGE>
 
the size of the principal payment. The average life is typically used as a 
proxy for maturity because the debt is amortized, rather than being paid off 
entirely at maturity, as would be the case in a straight debt instrument. 

CMOs and REMICs are typically structured as "pass-through" securities. In 
these arrangements, the underlying mortgages are held by the issuer, which 
then issues debt collateralized by the underlying mortgage assets. The 
security holder thus owns an obligation of the issuer and payment of interest 
and principal on such obligations is made from payments generated by the 
underlying mortgage assets. The underlying mortgages may be guaranteed as to 
payment of principal and interest by an agency or instrumentality of the U.S. 
Government such as GNMA or otherwise backed by FNMA or FHLMC. Alternatively, 
such securities may be backed by mortgage insurance, letters of credit, 
subordination or other credit enhancing features. Both CMOs and REMICs are 
issued by private entities. They are not directly guaranteed by any 
government agency and are secured by the collateral held by the issuer. 

Asset-Backed Securities 
Asset-backed securities are collateralized by short-term loans such as 
automobile loans, computer leases, or credit card receivables. The payments 
from the collateral are passed through to the security holder. As noted above 
with respect to CMOs and REMICs, the average life for these securities is the 
conventional proxy for maturity. Asset-backed securities may pay all interest 
and principal to the holder, or they may pay a fixed rate of interest, with 
any excess over that required to pay interest going either into a reserve 
account or to a subordinate class of securities, which may be retained by the 
originator. The originator may guarantee interest and principal payments. 
These guarantees often do not extend to the whole amount of principal, but 
rather to an amount equal to a multiple of the historical loss experience of 
similar portfolios. 

Other asset-backed securities are similar to CMOs and REMICs in structure and 
operations. Two varieties of asset-backed securities are CARs and CARDs. CARs 
are securities, representing either ownership interests in fixed pools of 
automobile receivables, or debt instruments supported by the cash flows from 
such a pool. CARDs are participations in fixed pools of credit accounts. 
These securities have varying terms and degrees of liquidity. 

CMOs, REMICs and other asset-backed securities are subject to the type of 
prepayment risk discussed above due to the possibility that prepayments on 
the underlying assets will alter the cash flow. The collateral behind 
asset-backed securities tends to have prepayment rates that do not vary with 
interest rates; the short-term nature of the loans may also tend to reduce 
the impact of any change in prepayment level. However, faster prepayments 
will shorten the average life and slower prepayments will lengthen it. Asset- 
backed securities may be pass-through, representing actual equity ownership 
of the underlying assets, or pay-through, representing debt instruments 
supported by cash flows from the underlying assets. 

The coupon rate of interest on mortgage-related and asset-backed securities 
is lower than the interest rates paid on the mortgages included in the 
underlying pool, by the amount of the fees paid to the mortgage pooler, 
issuer, and/or guarantor. Actual yield may vary from the coupon rate, 
however, if such securities are purchased at a premium or discount, traded in 
the secondary market at a premium or discount, or to the extent that the 
underlying assets are prepaid as noted above. 

High Risk High-Yield Securities 
The Fund may invest in high risk high-yield securities ("junk bonds") which 
are fixed income securities that offer a current yield above that generally 
available on debt securities rated in the four highest categories by Moody's 
Investors Service, Inc. ("Moody's") and Standard & Poor's Corporation ("S&P") 
or, if unrated, considered to be of comparable quality by the investment 
adviser. These securities (junk bonds) include: 

(a) fixed rate corporate debt obligations (including bonds, debentures and 
    notes) rated Ba or lower by Moody's or BB or lower by S&P; 

(b) preferred stocks that have yields comparable to those of high-yielding 
    debt securities; and 

(c) any securities convertible into any of the foregoing. 

                                                        Aetna Income Shares 11 
<PAGE>
 
Debt obligations rated BB/Ba or lower are regarded as speculative, and 
generally involve more risk of loss of principal and income than higher-rated 
securities. Also their yields and market values tend to fluctuate more. 
Fluctuations in value do not affect the cash income from the securities but 
are reflected in the Fund's net asset value. The greater risks and 
fluctuations in yield and value occur, in part, because investors generally 
perceive issuers of lower-rated and unrated securities to be less 
creditworthy. Lower ratings, however, may not necessarily indicate higher 
risks. In pursuing the Fund's objectives, the Company seeks to identify 
situations in which the rating agencies have not fully perceived the value of 
the security or in which the Company believes that future developments will 
enhance the creditworthiness and the ratings of the issuer. The Fund will not 
invest in any debt security rated lower than B. 

The yields earned on high risk high-yield securities (junk bonds) generally 
are related to the quality ratings assigned by recognized ratings agencies. 
These securities tend to offer higher yields than those of other securities 
with the same maturities because of the additional risks associated with 
them. These risks include: 

(1) Sensitivity to Interest Rate and Economic Changes. High risk high-yield 
    securities (junk bonds) are more sensitive to adverse economic changes or 
    individual corporate developments but less sensitive to interest rate 
    changes than are investment grade bonds. As a result, when interest rates 
    rise, causing bond prices to fall, the value of these securities may not 
    fall as much as investment grade corporate bonds. Conversely, when 
    interest rates fall, these securities may underperform investment grade 
    corporate bonds because the prices of these securities tend not to rise 
    as much as the prices of these other bonds. 

    Also, the financial stress resulting from an economic downturn or adverse 
    corporate developments could have a greater negative effect on the 
    ability of issuers of high risk high-yield securities (junk bonds) to 
    service their principal and interest payments, to meet projected business 
    goals and to obtain additional financing, than on more creditworthy 
    issuers. Holders of these securities could also be at greater risk 
    because these securities are generally unsecured and subordinated to 
    senior debt holders and secured creditors. If the issuer of a high risk 
    high-yield security (junk bond) owned by the Fund defaults, the Fund may 
    incur additional expenses to seek recovery. In addition, periods of 
    economic uncertainty and changes can be expected to result in increased 
    volatility of market prices of these securities and the Fund's net asset 
    value. Furthermore, in the case of high risk high- yield securities (junk 
    bonds) structured as zero coupon or pay-in-kind securities, their market 
    prices are affected to a greater extent by interest rate changes and 
    thereby tend to be more speculative and volatile than securities which 
    pay interest periodically and in cash. 

(2) Payment Expectations. High risk high-yield securities (junk bonds), 
    present risks based on payment expectations. For example, these 
    securities may contain redemption or call provisions. If an issuer 
    exercises these provisions in a declining interest rate market, the Fund 
    may have to replace the securities with a lower yielding security, 
    resulting in a decreased return for investors. Also, the value of these 
    securities may decrease in a rising interest rate market. In addition, 
    there is a higher risk of non-payment of interest and/or principal by 
    issuers of these securities than in the case of investment grade bonds. 

(3) Liquidity and Valuation Risks. High risk high-yield securities (junk 
    bonds) are often traded among a small number of broker-dealers rather 
    than in a broad secondary market. Purchasers of these securities tend to 
    be institutions rather than individuals, a factor that further limits the 
    secondary market. Many of these securities may not be as liquid as 
    investment grade bonds. The ability to value or sell these securities 
    will be adversely affected to the extent that such securities are thinly 
    traded or illiquid. Adverse publicity and investor perceptions, whether 
    or not based on fundamental analysis, may decrease or increase the values 
    and liquidity of high risk high-yield securities (junk bonds) more than 
    other securities, especially in a thinly-traded market. 

(4) Limitations of Credit Ratings. The credit ratings assigned to high risk 
    high-yield securities (junk bonds) may not accurately reflect the true 
    risks of an investment. Credit ratings typically evaluate 

12 Aetna Income Shares 
<PAGE>
 
    the safety of principal and interest payments rather than the market 
    value risk of such securities. In addition, credit agencies may fail to 
    adjust credit ratings to reflect rapid changes in economic or company 
    conditions that affect a security's market value. Although the ratings of 
    recognized rating services such as Moody's and S&P are considered, the 
    Company primarily relies on its own credit analysis which includes a 
    study of existing debt, capital structure, ability to service debts and 
    to pay dividends, the issuer's sensitivity to economic conditions, its 
    operating history and the current trend of earnings. Thus the achievement 
    of the Fund's investment objective may be more dependent on the Company's 
    own credit analysis than might be the case for a fund which does not 
    invest in high risk high-yield securities (junk bonds). 

(5) Congressional Proposals. New laws and proposed new laws may have a 
    negative impact on the market for high risk high-yield securities (junk 
    bonds). As examples, recent legislation requires federally-insured 
    savings and loan associations to divest themselves of their investments 
    in such securities and other proposals are designed to limit the use of, 
    or tax and other advantages of, these securities. Any such proposals, if 
    enacted, could have a negative effect on the Fund's net asset value. 

Zero Coupon and Pay-in-Kind Securities 
Zero coupon, or deferred interest, securities are debt obligations that do 
not entitle the holder to any periodic payment of interest prior to maturity 
or a specified date when the securities begin paying current interest (the 
"cash payment date") and therefore are issued and traded at a discount from 
their face amounts or par value. The discount varies, depending on the time 
remaining until maturity or cash payment date, prevailing interest rates, 
liquidity of the security and the perceived credit quality of the issuer. The 
discount, in the absence of financial difficulties of the issuer, decreases 
as the final maturity or cash payment date of the security approaches. The 
market prices of zero coupon and delayed interest securities generally are 
more volatile than the market prices of securities with similar maturities 
that pay interest periodically and are likely to respond to changes in 
interest rates to a greater degree than do non-zero coupon securities having 
similar maturities and credit quality. 

The risks associated with lower-rated debt securities may apply to zero 
coupon and pay-in-kind securities. These securities are also subject to the 
risk that in the event of a default, the Fund may realize no return on its 
investment, because these securities do not pay cash interest. 

When-Issued or Delayed-Delivery Securities 
During any period that the Fund has outstanding a commitment to purchase 
securities on a when-issued or delayed-delivery basis, the Fund will maintain 
a segregated account consisting of cash, U.S. Government securities or other 
high-quality debt obligations with its custodian bank. To the extent that the 
market value of securities held in this segregated account falls below the 
amount that the purchasing Fund will be required to pay on settlement, 
additional assets may be required to be added to the segregated account. Such 
segregated accounts could affect the purchasing Fund's liquidity and ability 
to manage its portfolio. When the Fund engages in when-issued or 
delayed-delivery transactions, it is effectively relying on the seller of 
such securities to consummate the trade; failure of the seller to do so may 
result in the Fund's incurring a loss or missing an opportunity to invest 
funds held in the segregated account more advantageously. 

The Fund will not pay for securities purchased on a when-issued or 
delayed-delivery basis, or start earning interest on such securities, until 
the securities are actually received. However, any security so purchased will 
be recorded as an asset of the Fund at the time the commitment is made. 
Because the market value of securities purchased on a when-issued or 
delayed-delivery basis may increase or decrease prior to settlement as a 
result of changes in interest rates or other factors, such securities will be 
subject to changes in market value prior to settlement and a loss may be 
incurred if the value of the security to be purchased declines prior to 
settlement. 

Convertibles 
A convertible bond or convertible preferred stock gives the holder the option 
of converting these securities into common stock. Convertible securities also 
contain a call feature whereby the issuer may redeem the security at a 
stipulated price, thereby limiting the possible appreciation. 

                                                        Aetna Income Shares 13 
<PAGE>
 
Illiquid and Restricted Securities 

   
The Fund may invest up to 15% of its total assets in illiquid securities. For 
this purpose, "illiquid securities" are those which cannot be sold in seven 
days in the ordinary course of business without taking a materially reduced 
price. Because of the absence of a trading market for these investments, the 
Fund may take longer to liquidate the position and may realize less than the 
amount originally paid by the Fund. The Fund may purchase securities, which, 
while privately placed, are eligible for purchase and sale pursuant to Rule 
144A under the 1933 Act. This rule permits certain qualified institutional 
buyers, such as the Fund, to trade in privately placed securities even though 
such securities are not registered under the 1933 Act. The Company, under the 
supervision of the Board of Trustees of the Fund, will consider whether 
securities purchased under Rule 144A and other restricted securities are 
illiquid and thus subject to the Fund's restriction of investing no more than 
15% of the Fund's total assets in illiquid securities. In making this 
determination, the Company will consider the trading markets for the specific 
security taking into account the unregistered nature of the Rule 144A 
security. In addition, the Company considers, among other things, the (i) 
frequency of trades and quotes, (ii) number of dealers and potential 
purchasers, (iii) dealer undertakings to make a market, and (iv) nature of 
the security and market place trades. The liquidity of Rule 144A securities 
will also be monitored by the Company and, if as a result of changed 
conditions, it is determined that a Rule 144A security is no longer liquid, 
the Fund's holdings of illiquid securities will be reviewed to assure that 
the Fund does not invest more than 15% of its total assets in illiquid 
securities. Investing in Rule 144A securities could have the effect of 
increasing the amount of the Fund's investments in illiquid securities if 
qualified institutional buyers are unwilling to purchase such securities. At 
the present time, it is not possible to predict with certainty how the market 
for Rule 144A securities will develop. 
    

Warrants 
Warrants allow the holder to purchase new shares in the issuing company at a 
predetermined price within either a specified length of time or perpetually. 
Warrants may be sold individually or attached to preferred stock or bonds. If 
the warrant is not exercised the Fund would lose the amount paid for the 
warrant. 

The purchaser of a warrant expects that the market price of a security will 
exceed the purchase price of the warrant plus the exercise price of the 
warrant, thus giving him a profit. 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. 

Borrowing 
The Fund may borrow up to 5% of the value of its total assets for temporary 
or emergency purposes. The Fund may also borrow up to one-third of the value 
of its total assets from banks (including its custodian bank) to increase its 
holdings of portfolio securities. Leveraging by means of borrowing may affect 
the Fund's net asset value by exaggerating any increase or decrease in the 
value of portfolio securities, and money borrowed is subject to interest and 
other costs which may or may not exceed the income derived from the 
securities purchased with borrowed funds. There is no present intention to 
leverage the Fund. 

Portfolio Turnover 

   
Portfolio turnover refers to the frequency of portfolio transactions and the 
percentage of portfolio assets being bought and sold in the aggregate during 
the year. The Fund does not intend to make a general practice of short-term 
trading, although it may occasionally realize short-term gains or losses. 
Purchases and sales will be made whenever such action is deemed prudent and 
consistent with investment objectives. It is anticipated that under normal 
market conditions the average annual portfolio turnover rate will not exceed 
125%. A high turnover rate involves greater expenses and may involve greater 
risk to the Fund. The portfolio turnover rates for 1994 and 1995 were 74% and 
__%, respectively.

              CONTROL PERSONS AND PRINCIPAL HOLDERS OF THE FUND 
   
As of March 31, 1996, the Company and its affiliates owned ( %) shares of the
Fund which were allocated to variable annuity and variable life insurance
separate accounts to fund obligations under variable annuity contracts and
variable life insurance contracts. Contract holders in these separate accounts
are provided the right to direct the voting of Fund shares at shareholder
meetings. The Company and its affiliates vote the shares that they own in these
separate accounts in accordance with contract holders' directions. Undirected
shares of the Fund will be voted for each Account in the same proportion as
directed shares. The Company is a wholly owned subsidiary of Aetna Retirement
Services, Inc., which is in turn a wholly owned subsidiary of Aetna Life and
Casualty Company located at 151 Farmington Avenue, Hartford, Connecticut 06156.

<PAGE>
 
   
An additional        shares (less than 1%) of the Fund were owned by an 
affiliate of the Company at that date. All these shares are voted by the 
affiliated companies at their sole discretion. Officers and Trustees own less 
than 1% of the outstanding shares of Income Shares. 
    
                       THE INVESTMENT ADVISORY CONTRACT 
   
The Fund has entered into an Investment Advisory Agreement (the "Management
Agreement") with the Company, effective as of January 1, 1996. A prior
investment advisory agreement, with substantially identical terms, was
previously in effect. Under the Management Agreement and subject to the
direction of the Board of Trustees of the Fund, the Company has responsibility
for supervising all aspects of the operations of the Fund. For its services
under the Management Agreement, the Company receives an annual investment
advisory fee of 0.25% of the average daily net assets of the Fund. See
"Management of the Fund" in the Prospectus.
    

The Management Agreement provides that the Company shall pay (a) the 
salaries, employment benefits and other related costs of those of its 
personnel engaged in providing investment advice to the Fund, including, 
without limitation, office space, office equipment, telephone and postage 
costs and (b) any fees and expenses of all Trustees of the Fund who are 
employees of the Company or an affiliated entity and any salaries and 
employment benefits of officers of the Fund who are affiliated persons of the 
Company for acting as officers of the Fund. The Management Agreement also 
provides that the Fund will pay (i) investment advisory fees; (ii) broker's 
commissions and certain other transaction fees including the portion of such 
fees, if any, which is attributable to brokerage research services; (iii) 
fees and expenses of the Fund's independent auditors and outside legal 
counsel; (iv) expenses of printing and distributing proxies, proxy 
statements, prospectuses and reports to shareholders of the Fund, except as 
such expenses may be borne by the distributor; (v) interest and taxes; (vi) 
fees and expenses of those of the Fund's Trustees who are not "interested 
persons" (as defined by the 1940 Act) of the Fund or the Company; (vii) 
shareholder's meeting expenses; (viii) Administrator, transfer agent, 
custodian and dividend disbursing agent fees and expenses; (ix) fees of 
dividend, accounting and pricing agents appointed by the Fund; (x) fees 
payable to the SEC or in connection with the registration of shares of the 
Fund under the laws of any state or territory of the United States or the 
District of Columbia; (xi) fees and assessments of the Investment Company 
Institute or any successor organization other association memberships 
approved by the Board of Trustees; (xii) such nonrecurring or extraordinary 
expenses as may arise; (xiii) all other ordinary business expenses incurred 
in the operations of the Fund, unless specifically allocable otherwise by the 
Management Agreement; (xiv) costs attributable to investor services, 
administering shareholder accounts and handling shareholder relations; (xv) 
all expenses incident to the payment of any dividend, distribution, 
withdrawal of redemption; and (xvi) insurance premiums on property and 
personnel (including officers and Trustees) of the Fund which inure to its 
benefit. 

The Management Agreement provides that if, for any fiscal year, the total of 
all ordinary business expenses of the Fund, including all investment advisory 
fees but excluding brokerage commissions, distribution fees, taxes, interest 
and extraordinary expenses and certain other excludable expenses, would 
exceed the most restrictive expense limits imposed by any statute or 
regulatory authority of any jurisdiction in which shares of the Fund are 
offered for sales (unless a waiver is obtained), the Company shall reduce its 
advisory fee in order to reduce such excess expenses, but will not be 
required to reimburse the Fund for any ordinary business expenses which 
exceed the amount of its advisory fee for such fiscal year. 

The Management Agreement provides that it will continue in effect from year 
to year provided that it is specifically approved at least annually by the 
Board of Trustees of the Fund and by a majority of the non- interested 
Trustees by votes cast at a meeting called for such purpose. The Management 
Agreement provides that it may be terminated at any time by vote of the 
Fund's Trustees or by vote of a majority of the Fund's outstanding voting 
securities, or the Company, on sixty (60) days' written notice to the other 
party. The Management Agreement will terminate automatically in the event of 
its assignment. 

18 Aetna Income Shares 
<PAGE>
 
   
Pursuant to the terms of the previous management agreement, the Company 
received an annual investment advisory fee of 0.25% of the average daily net 
assets of the Fund. For the years 1993, 1994 and 1995, the Fund paid the 
Company an investment advisory fee of $1,476,853, $1,470,846 and $ 
respectively. 
    

The service mark of Aetna Income Shares and the name "Aetna" have been 
adopted by the Fund with the permission of Aetna Life and Casualty Company 
and their continued use is subject to the right of Aetna Life and Casualty 
Company to withdraw this permission in the event the Company or another 
subsidiary or affiliated corporation of Aetna Life and Casualty Company 
should not be the investment adviser of Income Shares. 

                      ADMINISTRATIVE SERVICES AGREEMENT 

   
The Fund has entered into an Administrative Services Agreement with the Company
effective May 1, 1996 under which the Company has agreed to provide all
administrative services in support of the Fund. In addition, the Company has
agreed to assume all ordinary recurring direct costs of the Fund that it would
be required to pay under the terms of the Investment Advisory Agreement. As a
result, the Company will be covering all costs of the Fund other than the
investment advisory fee and brokerage costs and other transaction costs in
connection with the purchase and sale of securities for its portfolio. For the
services provided under the Administrative Services Agreement, the Company will
receive an annual fee, payable monthly at a rate of 0.10% of the average daily
net assets of the Fund. Prior to May 1, 1996, the Company had an Administrative
Services Agreement that provided for the reimbursement of a proportionate share
of the Company's overhead in administering the Fund. The Fund was obligated to
pay its own direct costs. The total of the direct costs and administrative costs
for the years ended December 31, 1993, 1994 and 1995 were $186,392, $207,233 and
$    , respectively.

The Administrative Services Agreement was approved by the Board of Trustees 
on February 28, 1996 and will remain in effect until January, 1997. It will 
then remain in effect from year-to-year if approved annually by a majority of 
the Trustees. It may be terminated by either party on sixty days' written 
notice. 
    

                             BROKERAGE ALLOCATION 

Subject to the direction of the Fund's Board of Trustees, the Company has 
responsibility for making Income Shares' investment decisions, for effecting 
the execution of trades for the Fund's portfolio and for negotiating any 
brokerage commissions thereon. It is the policy of the Company to obtain the 
best quality of execution available, giving attention to net price (including 
commissions where applicable), execution capability (including the adequacy 
of a firm's capital position), and other services related to execution; the 
relative priority given to these factors will depend on all of the 
circumstances regarding a specific trade. 

In implementing its trading policy, the Company may place the Fund's 
portfolio transactions with such brokers or dealers and for execution in such 
markets as, in the opinion of the Company, will lead to best overall quality 
of execution for the Fund's portfolio. 

The Company currently receives a variety of brokerage and research services 
from brokerage firms in return for the execution by such brokerage firms of 
trades in securities held by the Fund. These brokerage and research services 
include, but are not limited to, quantitative and qualitative research 
information and purchase and sale recommendations regarding securities and 
industries, analyses and reports covering a broad range of economic factors 
and trends, statistical data relating to the strategy and performance of 
Income Shares and other investment companies, services related to the 
execution of trades in the Fund's securities and advice as to the valuation 
of securities. The Company considers the quantity and quality of such 
brokerage and research services provided by a brokerage firm along with the 
nature and difficulty of the specific transaction in negotiating commissions 
for trades in the Fund's securities. 

Consistent with federal legislation, the Company may obtain such brokerage 
and research services regardless of whether they are paid for (1) by means of 
commissions; or (2) by means of separate, non- 

                                                        Aetna Income Shares 19 
<PAGE>
 
commission payments. The Company's judgment as to whether and how it will 
obtain the specific brokerage and research services will be based upon its 
analysis of the quality of such services and the cost (depending upon the 
various methods of payment which may be offered by brokerage firms) and will 
reflect the Company's opinion as to which services and which means of payment 
are in the long-term best interests of the Fund. The Fund has no present 
intention to effect any brokerage transactions in portfolio securities with 
the Company or any affiliate of the Fund or the Company. 

Certain executive officers of the Company also have supervisory 
responsibility with respect to the securities portfolio of the Company's own 
general account. Further, the Company also acts as investment adviser to 
other investment companies registered under the 1940 Act. In placing orders 
for the purchase and sale of securities for the Fund, the Company will 
normally use its own facilities and there will not be allocations of such 
orders between the Fund and the Company's general account. However, to the 
extent the Company has other clients, the Fund and another advisory client of 
the Company may desire to buy or sell the same publicly traded security at or 
about the same time. In such a case, the purchases or sales will normally be 
allocated as nearly as practicable on a pro rata basis in proportion to the 
amounts to be purchased or sold by each. In some cases the smaller orders 
will be filled first. In determining the amounts to be purchased and sold, 
the main factors to be considered are the respective investment objectives of 
the Fund and the other portfolios, the relative size of portfolio holdings of 
the same or comparable securities, availability of cash for investment by the 
Fund and the other portfolios, and the size of their respective investment 
commitments. Trades may be executed between Funds and such trades are 
executed at "current market price" in compliance with SEC Rule 17a-7. 

   
Most purchases and sales of portfolio securities are made in principal 
transactions and do not involve payment of brokerage commissions. For 1993, 
1994 and 1995, Income Shares paid brokerage commissions of $35,562, $56,222 
and $       respectively. 

For the fiscal year ended December 31, 1995, portfolio transactions in the
amount of $____ were directed to certain brokers because of research services,
of which commissions in the amount of $____ were paid with respect to such
transactions. No brokerage business was placed with any brokers affiliated with
ALIAC during the last three fiscal years.
    

                            DESCRIPTION OF SHARES 

Aetna Income Shares was established under the laws of Massachusetts by a 
Declaration of Trust ("Declaration") dated January 25, 1984. 

The Declaration permits the Trustees to issue an unlimited number of full and 
fractional shares of beneficial interest of a single class, each of which 
represents a proportionate interest in the Fund equal to each other share. 
The Trustees have the power to divide or combine the shares into a greater or 
lesser number of shares without thereby changing the proportional beneficial 
interest in the Fund. 

Upon liquidation of Income Shares, shareholders are entitled to share pro 
rata in the net assets of the Fund available for distribution to 
shareholders. Fund shares are fully paid and nonassessable, except as set 
forth below. 

Shareholder and Trustee Liability 
Income Shares is an entity of the type commonly known as a "Massachusetts 
business trust." Under Massachusetts law, shareholders of such business trust 
may, under certain circumstances, be held personally liable as partners for 
the obligations of the Fund, which is not true in the case of a corporation. 
The Declaration provides that shareholders shall not be subject to any 
personal liability for the acts or obligations of the Fund and that every 
written agreement, obligation, instrument or undertaking made by the Fund 
shall contain a provision to the effect that shareholders are not personally 
liable thereunder. With respect to tort claims, contract claims where the 
provision referred to is omitted from the undertaking, and claims for taxes 
and certain statutory liabilities in other jurisdictions, a shareholder may 
be held personally liable to the extent that claims are not satisfied by the 
Fund. However, upon payment of any such liability the shareholder will be 
entitled to reimbursement from the general assets of the Fund. The Trustees 
intend to conduct the operations of the Fund, with the advice of counsel, in 
such a way as to avoid, as far as possible, ultimate liability of the 
shareholders for liabilities of the Fund.

The Declaration further provides that the Trustees will not be liable for 
errors of judgment or mistakes of fact or law, but nothing in the Declaration 
protects a Trustee against any liability to which he or she would otherwise 
be subject by reason of willful misfeasance, bad faith, gross negligence, or 
reckless disregard of the duties involved in the conduct of his or her 
office. 

Voting Rights 
Shareholders are entitled to one vote for each full share held (and 
fractional votes for fractional shares held) and will vote in the election of 
Trustees (to the extent hereinafter provided) and on other matters submitted 
to the vote of shareholders. A meeting of the shareholder at which Trustees 
were elected was most recently held on April 13, 1994. Thereafter, no further 
meeting of shareholders for the purpose of electing Trustees will be held 
unless and until such time as less than a majority of the Trustees holding 
office have been elected by shareholders, at which time the Trustees then in 
office will call a shareholders' meeting for election of Trustees. Vacancies 
occurring between such meetings shall be filled in an otherwise legal manner 
if, immediately after filling any such vacancy, at least two-thirds of the 
Trustees holding office have been elected by shareholders. Except as set 
forth above, the Trustees shall continue to hold office and may appoint 
successor Trustees. Trustees may be removed from office (1) at any time by 
two-thirds vote of the Trustees; (2) by a majority vote of Trustees where any 
Trustee becomes mentally or physically incapacitated; (3) at a special 
meeting of shareholders by a two-thirds vote of the outstanding shares; (4) 
by written declaration filed with Mellon Bank, N.A., the Fund's custodian, 
signed by two-thirds of the Fund's shareholders. Any Trustee may also 
voluntarily resign from office. Voting rights are not cumulative, so that the 
holders of more than 50% of the shares voting in the election of Trustees 
can, if they choose to do so, elect all the Trustees of Income Shares, in 
which event the holders of the remaining shares will be unable to elect any 
person as a Trustee. 

The Declaration may be amended by an affirmative vote of a majority of the 
shares at any meeting of shareholders or by written instrument signed by a 
majority of the Trustees and consented to by a majority of the shareholders. 
The Trustees may also amend the Declaration without the vote or consent of 
shareholders if they deem it necessary to conform the Declaration to the 
requirements of applicable federal laws or regulations or the requirements of 
the regulated investment company provisions of the Internal Revenue Code of 
1986, as amended, but the Trustees shall not be liable for failing to do so. 

Shares have no preemptive or conversion rights. 

                        SALE AND REDEMPTION OF SHARES 

Shares of Income Shares are sold and redeemed at the net asset value next 
determined after receipt of a purchase or redemption order in acceptable form 
by Firstar Trust Company ("Firstar"). No sales charge or redemption charge is 
made. The value of shares redeemed may be more or less than the shareholder's 
cost, depending upon the market value of the portfolio securities at the time 
of redemption. Payment for shares redeemed will be made within seven days 
after the redemption request is received in proper form by Firstar. Any 
written request to redeem shares must bear the signatures of all the 
registered holders of those shares. The signatures must be guaranteed by a 
commercial bank, trust company or a member of a national securities exchange. 
Firstar will, on request, explain any additional requirements for shares held 
in the name of a corporation, partnership, trustee, guardian or in any other 
representative capacity. However, the right to redeem Fund shares may be 
suspended or payment therefore postponed for any period during which (a) 
trading on the New York Stock Exchange is restricted as determined by the SEC 
or such Exchange is closed for other than weekends and holidays; (b) an 
emergency exists, as determined by the SEC, as a result of which (i) disposal 
by the Fund of securities owned by it is not reasonably practicable, or (ii) 
it is not reasonably practicable for the Fund to determine fairly the value 
of its net assets; or (c) the SEC by order so permits for the protection of 
shareholders of the Fund. 

An open account is automatically set up and maintained for each shareholder 
to facilitate the voluntary accumulation of Income Shares shares. The open 
account system makes unnecessary the issuance and delivery of stock 
certificates, thereby relieving shareholders of the responsibility of 
safekeeping. Through 

                                                        Aetna Income Shares 21 
<PAGE>
 
the open account system, each shareholder is informed of his or her holdings 
after any transaction affecting the number of shares he or she owns. Share 
certificates will not be issued. 

                            PRINCIPAL UNDERWRITER 
   
The Company is the principal underwriter of Income Shares pursuant to a 
contract ("Distribution Agreement") between it and the Fund effective 
January 1, 1996. The Distribution Agreement may be continued annually if 
approved annually by the Board of Trustees of the Fund or by a vote of 
holders of a majority of the Fund's shares, and by a vote of a majority of 
the Fund's Board of Trustees who are not "interested persons," as that term 
is defined in the 1940 Act, of the Company, and who are not interested 
persons of the Fund, appearing in person at a meeting called for the purpose 
of approving such agreement. This agreement terminates automatically upon 
assignment, and may be terminated at any time on sixty (60) days' written 
notice by the Fund's Board of Trustees or by vote of holders of a majority of 
the Fund's shares without the payment of any penalty. 
    
                                 TAX MATTERS 

The following is only a summary of certain additional tax considerations 
generally affecting the Fund and its shareholders that are not described in 
the Prospectus. No attempt is made to present a detailed explanation of the 
tax treatment of the Fund or its shareholders, and the discussions here and 
in the Prospectus are not intended as substitutes for careful tax planning. 
Holders of variable annuity contracts or variable life insurance policies 
must consult the prospectuses of their respective contracts or policies for 
information concerning the federal income tax consequences of owning such 
variable annuity contracts or variable life insurance policies. 

Qualification as a Regulated Investment Company 
The Fund has elected to be taxed as a regulated investment company under 
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). 
As a regulated investment company, the Fund is not subject to federal income 
tax on the portion of its net investment income (i.e., taxable interest, 
dividends and other taxable ordinary income, net of expenses) and capital 
gain net income (i.e., the excess of capital gains over capital losses) that 
it distributes to shareholders, provided that it distributes at least 90% of 
its investment company taxable income (i.e., net investment income and the 
excess of net short-term capital gain over net long-term capital loss) for 
the taxable year (the "Distribution Requirement"), and satisfies certain 
other requirements of the Code that are described below. Distributions by the 
Fund made during the taxable year or, under specified circumstances, within 
twelve months after the close of the taxable year, will be considered 
distributions of income and gains of the taxable year and can therefore 
satisfy the Distribution Requirement. 

In addition to satisfying the Distribution Requirement, a regulated 
investment company must: (1) derive at least 90% of its gross income from 
dividends, interest, certain payments with respect to securities loans, gains 
from the sale or other disposition of stock or securities or foreign 
currencies (to the extent such currency gains are directly related to the 
regulated investment company's principal business of investing in stock or 
securities) and other income (including but not limited to gains from 
options, futures or forward contracts) derived with respect to its business 
of investing in such stock, securities or currencies (the "Income 
Requirement"); and (2) derive less than 30% of its gross income (exclusive of 
certain gains on designated hedging transactions that are offset by realized 
or unrealized losses on offsetting positions) from the sale or other 
disposition of stock, securities or foreign currencies (or options, futures 
or forward contracts thereon) held for less than three months (the 
"Short-Short Gain Test"). However, foreign currency gains, including those 
derived from options, futures and forwards, will not in any event be 
characterized as Short-Short Gain if they are directly related to the 
regulated investment company's investments in stock or securities (or options 
or futures thereon). Because of the Short-Short Gain Test, the Fund may have 
to limit the sale of appreciated securities that it has held for less than 
three months. However, the Short-Short Gain Test will not prevent the Fund 
from disposing of investments at a loss, since the recognition of a loss 
before the expiration of the three-month holding period is disregarded for 

22 Aetna Income Shares 
<PAGE>
 
this purpose. Interest (including original issue discount) received by the 
Fund at maturity or upon the disposition of a security held for less than 
three months will not be treated as gross income derived from the sale or 
other disposition of such security within the meaning of the Short-Short Gain 
Test. However, income that is attributable to realized market appreciation 
will be treated as gross income from the sale or other disposition of 
securities for this purpose. 

In general, gain or loss recognized by the Fund on the disposition of an 
asset will be a capital gain or loss. However, gain recognized on the 
disposition of a debt obligation purchased by the Fund at a market discount 
(generally, at a price less than its principal amount) will be treated as 
ordinary income to the extent of the portion of the market discount which 
accrued during the period of time the Fund held the debt obligation. In 
addition, under the rules of Code Section 988, gain or loss recognized on the 
disposition of a debt obligation denominated in a foreign currency or an 
option with respect thereto (but only to the extent attributable to changes 
in foreign currency exchange rates), and gain or loss recognized on the 
disposition of a foreign currency forward contract, futures contract, option 
or similar financial instrument, or of foreign currency itself, except for 
regulated futures contracts or non-equity options subject to Code Section 
1256, will generally be treated as ordinary income or loss. For purposes of 
determining whether capital gain or loss recognized by the Fund on the 
disposition of an asset is long-term or short-term, the holding period of the 
asset may be affected if (i) the asset is used to close a "short sale" (which 
includes for certain purposes the acquisition of a put option) or is 
substantially identical to another asset so used, (ii) the asset is otherwise 
held by the Fund as part of a "straddle" (which term generally excludes a 
situation where the asset is stock and the Fund grants a qualified covered 
call option (which, among other things, must not be deep-in-the-money) with 
respect thereto) or (iii) the asset is stock and the Fund grants an 
in-the-money qualified covered call option with respect thereto. However, for 
purposes of the Short-Short Gain Test, the holding period of the asset 
disposed of may be reduced only in the case of clause (i) above. In addition, 
the Fund may be required to defer the recognition of a loss on the 
disposition of an asset held as part of a straddle to the extent of any 
unrecognized gain on the offsetting position. 

Any gain recognized by the Fund on the lapse of, or any gain or loss 
recognized by the Fund from a closing transaction with respect to, an option 
written by the Fund will be treated as a short-term capital gain or loss. For 
purposes of the Short-Short Gain Test, the holding period of an option 
written by the Fund will commence on the date it is written and end on the 
date it lapses or the date a closing transaction is entered into. 
Accordingly, the Fund may be limited in its ability to write options which 
expire within three months and to enter into closing transactions at a gain 
within three months of the writing of options. 

Transactions that may be engaged in by the Fund (such as regulated futures 
contracts, certain foreign currency contracts, and options on stock indexes 
and futures contracts) will be subject to special tax treatment as "Section 
1256 contracts." Section 1256 contracts are treated as if they are sold for 
their fair market value on the last business day of the taxable year, even 
though a taxpayer's obligations (or rights) under such contracts have not 
terminated (by delivery, exercise, entering into a closing transaction or 
otherwise) as of such date. Any gain or loss recognized as a consequence of 
the year-end deemed disposition of Section 1256 contracts is taken into 
account for the taxable year together with any other gain or loss that was 
previously recognized upon the termination of Section 1256 contracts during 
that taxable year. Any capital gain or loss for the taxable year with respect 
to Section 1256 contracts (including any capital gain or loss arising as a 
consequence of the year-end deemed sale of such contracts) is generally 
treated as 60% long-term capital gain or loss and 40% short-term capital gain 
or loss. The Fund, however, may elect not to have this special tax treatment 
apply to Section 1256 contracts that are part of a "mixed straddle" with 
other investments of the Fund that are not Section 1256 contracts. The IRS 
has held in several private rulings (and Treasury Regulations now provide) 
that gains arising from Section 1256 contracts will be treated for purposes 
of the Short- Short Gain Test as being derived from securities held for not 
less than three months if the gains arise as a result of a constructive sale 
under Code Section 1256. 

Treasury Regulations permit a regulated investment company, in determining 
its investment company taxable income and net capital gain (i.e., the excess 
of net long-term capital gain over net short-term capital loss) for any 
taxable year, to elect (unless it has made a taxable year election for excise 
tax purposes 

                                                        Aetna Income Shares 23 
<PAGE>
 
as discussed below) to treat all or any part of any net capital loss, any net 
long-term capital loss or any net foreign currency loss incurred after 
October 31 as if it had been incurred in the succeeding year. 

Finally, the Fund must satisfy an asset diversification test in order to 
qualify as a regulated investment company. Under this test, at the close of 
each quarter of the Fund's taxable year, at least 50% of the value of the 
Fund's assets must consist of cash and cash items, U.S. Government 
securities, securities of other regulated investment companies, and 
securities of other issuers (as to which the Fund has not invested more than 
5% of the value of the Fund's total assets in securities of such issuer and 
as to which the Fund does not hold more than 10% of the outstanding voting 
securities of such issuer), and no more than 25% of the value of its total 
assets may be invested in the securities of any one issuer (other than U.S. 
Government securities and securities of other regulated investment 
companies), or in two or more issuers which the Fund controls and which are 
engaged in the same or similar trades or businesses. Generally, an option 
(call or put) with respect to a security is treated as issued by the issuer 
of the security not the issuer of the option. However, with regard to forward 
currency contracts, there does not appear to be any formal or informal 
authority which identifies the issuer of such instrument. For purposes of 
asset diversification testing, obligations issued by or guaranteed by 
agencies and instrumentalities of the U.S. Government such as the Federal 
Agricultural Mortgage Corporation, the Farm Credit System Financial 
Assistance Corporation, the Federal Home Loan Bank, the Federal Home Loan 
Mortgage Corporation, the Federal National Mortgage Association, the 
Government National Mortgage Corporation, and the Student Loan Marketing 
Association are treated as U.S. Government securities. 

If for any taxable year the Fund does not qualify as a regulated investment 
company, all of its taxable income (including its net capital gain) will be 
subject to tax at regular corporate rates without any deduction for 
distributions to shareholders, and such distributions will be taxable to the 
shareholders as ordinary dividends to the extent of the Fund's current and 
accumulated earnings and profits. Such distributions generally will be 
eligible for the dividends-received deduction in the case of corporate 
shareholders. 

Qualification of Segregated Asset Accounts 

Under Code section 817(h), a segregated asset account upon which a variable 
annuity contract or variable life insurance policy is based must be 
"adequately diversified." A segregated asset account will be adequately 
diversified if it satisfies one of two alternative tests set forth in the 
Treasury Regulations. Specifically, the Treasury Regulations provide, that 
except as permitted by the "safe harbor" discussed below, as of the end of 
each calendar quarter (or within 30 days thereafter) no more than 55% of a 
fund's total assets may be represented by any one investment, no more than 
70% by any two investments, no more than 80% by any three investments and no 
more than 90% by any four investments. For this purpose, all securities of 
the same issuer are considered a single investment, and while each U.S. 
Government agency and instrumentality is considered a separate issuer, a 
particular foreign government and its agencies, instrumentalities and 
political subdivisions are considered the same issuer. As a safe harbor, a 
separate account will be treated as being adequately diversified if the 
diversification requirements under Subchapter M are satisfied and no more 
than 55% of the value of the account's total assets are cash and cash items, 
government securities and securities of other regulated investment companies. 

For purposes of these alternative diversification tests, a segregated asset 
account investing in shares of a regulated investment company will be 
entitled to "look-through" the regulated investment company to its pro rata 
portion of the regulated investment company's assets, provided the regulated 
investment company satisfies certain conditions relating to the ownership of 
the shares. 

Excise Tax on Regulated Investment Companies 

A 4% non-deductible excise tax is imposed on a regulated investment company 
that fails to distribute in each calendar year an amount equal to 98% of 
ordinary taxable income for the calendar year and 98% of capital gain net 
income for the one-year period ended on October 31 of such calendar year (or, 
at the election of a regulated investment company having a taxable year 
ending November 30 or December 31, for its taxable year (a "taxable year 
election")). The balance of such income must be distributed during 

24 Aetna Income Shares 
<PAGE>
 
the next calendar year. For the foregoing purposes, a regulated investment 
company is treated as having distributed any amount on which it is subject to 
income tax for any taxable year ending in such calendar year. 

For purposes of the excise tax, a regulated investment company shall: (1) 
reduce its capital gain net income (but not below its net capital gain) by 
the amount of any net ordinary loss for the calendar year; and (2) exclude 
foreign currency gains and losses incurred after October 31 of any year (or 
after the end of its taxable year if it has made a taxable year election) in 
determining the amount of ordinary taxable income for the current calendar 
year (and, instead, include such gains and losses in determining ordinary 
taxable income for the succeeding calendar year). 

The Fund intends to make sufficient distributions or deemed distributions of 
its ordinary taxable income and capital gain net income prior to the end of 
each calendar year to avoid liability for the excise tax. However, investors 
should note that the Fund may in certain circumstances be required to 
liquidate portfolio investments to make sufficient distributions to avoid 
excise tax liability. 

Fund Distributions 
The Fund anticipates distributing substantially all of its investment company 
taxable income for each taxable year. Such distributions will be taxable to 
shareholders as ordinary income and treated as dividends for federal income 
tax purposes, but they may qualify for the 70% dividends-received deduction 
for corporate shareholders. 

The Fund may either retain or distribute to shareholders its net capital gain 
for each taxable year. The Fund currently intends to distribute any such 
amounts. If net capital gain is distributed and designated as a capital gain 
dividend, it will be taxable to shareholders as long-term capital gain, 
regardless of the length of time a shareholder has held its shares or whether 
such gain was recognized by the Fund prior to the date on which the 
shareholder acquired his shares. All distributions paid to ALIAC or its 
affiliates, whether characterized as ordinary income or capital gain, are not 
taxable to variable annuity or variable life insurance contract holders. 

If the Fund elects to retain its net capital gain, the Fund will be taxed 
thereon (except to the extent of any available capital loss carryovers) at 
the 35% corporate tax rate. Where the Fund elects to retain its net capital 
gain, it is expected that the Fund also will elect to have shareholders of 
record on the last day of its taxable year treated as if each received a 
distribution of his pro rata share of such gain, with the result that each 
shareholder will be required to report his pro rata share of such gain on his 
tax return as long-term capital gain, will receive a refundable tax credit 
for his pro rata share of tax paid by the Fund on the gain, and will increase 
the tax basis for his shares by an amount equal to the deemed distribution 
less the tax credit. 

Investment income that may be received by the Fund from sources within 
foreign countries may be subject to foreign taxes withheld at the source. The 
United States has entered into tax treaties with many foreign countries which 
entitle the Fund to a reduced rate of, or exemption from, taxes on such 
income. It is impossible to determine the effective rate of foreign tax in 
advance since the amount of the Fund's assets to be invested in various 
countries is not known. 

Distributions by the Fund that do not constitute ordinary income dividends or 
capital gain dividends will be treated as a return of capital to the extent 
of (and in reduction of) the shareholder's tax basis in his shares; any 
excess will be treated as gain from the sale of his shares, as discussed 
below. 

Distributions paid to ALIAC or its affiliates will be reinvested in 
additional shares. Distributions to other shareholders will be reinvested in 
additional Fund shares unless Firstar Trust Company, the Fund's transfer 
agent, is otherwise notified in writing prior to the record date for such 
distributions. 

Shareholders receiving a distribution in the form of either cash or 
additional shares will be treated as receiving a distribution in an amount 
equal to the fair market value of the shares received, determined as of the 
reinvestment date. In addition, if the net asset value at the time a 
shareholder purchases shares 

                                                        Aetna Income Shares 25 
<PAGE>
 
of the Fund reflects undistributed net investment income or recognized 
capital gain net income, or unrealized appreciation in the value of the 
assets of the Fund, distributions of such amounts will be taxable to the 
shareholder in the manner described above, although such distributions 
economically constitute a return of capital to the shareholder. 

Ordinarily, shareholders are required to take distributions by the Fund into 
account in the year in which the distributions are made. However, dividends 
declared in October, November or December of any year and payable to 
shareholders of record on a specified date in such a month will be deemed to 
have been received by the shareholders (and made by the Fund) on December 31 
of such calendar year if such dividends are actually paid in January of the 
following year. Shareholders will be advised annually as to the U.S. federal 
income tax consequences of distributions made (or deemed made) during the 
year. 

Sale or Redemption of Shares 
Shareholders will recognize gain or loss on the sale or redemption of shares 
of the Fund in an amount equal to the difference between the proceeds of the 
sale or redemption and the shareholder's adjusted tax basis in the shares. 
All or a portion of any loss so recognized may be disallowed if the 
shareholder purchases other shares of the Fund within 30 days before or after 
the sale or redemption. In general, any gain or loss arising from (or treated 
as arising from) the sale or redemption of shares of the Fund will be 
considered capital gain or loss and will be long-term capital gain or loss if 
the shares were held for longer than one year. However, any capital loss 
arising from the sale or redemption of shares held for six months or less 
will be treated as a long-term capital loss to the extent of the amount of 
capital gain dividends received on such shares. For this purpose, the special 
holding period rules of Code Section 246(c)(3) and (4) generally will apply 
in determining the holding period of shares. Long-term capital gains of 
noncorporate taxpayers are currently taxed at a maximum rate 11.6% lower than 
the maximum rate applicable to ordinary income. Capital losses in any year 
are deductible only to the extent of capital gains plus, in the case of a 
noncorporate taxpayer, $3,000 of ordinary income. Although gain or loss 
realized on shares redeemed through the direction of variable annuity or 
variable life insurance contract holders is taxable to ALIAC or its 
affiliates, such variable annuity or variable life insurance contract holders 
will not be subject to tax. 

Effect of Future Legislation; Local Tax Considerations 
The foregoing general discussion of U.S. federal income tax consequences is 
based on the Code and the Treasury Regulations issued thereunder as in effect 
on the date of this Statement of Additional Information. Future legislative 
or administrative changes or court decisions may significantly change the 
conclusions expressed herein, and any such changes or decisions may have a 
retroactive effect with respect to the transactions contemplated herein. 

Rules of state and local taxation of ordinary income dividends and capital 
gain dividends from regulated investment companies often differ from the 
rules for U.S. federal income taxation described above. Shareholders are 
urged to consult their tax advisers as to the consequences of these and other 
state and local tax rules affecting investment in the Fund. 

                               NET ASSET VALUE 

Equity securities of the Fund which are traded on a registered securities 
exchange are valued at the last sale price or, if there has been no sale that 
day, at the mean of the last bid and asked price on the exchange where the 
security is principally traded. Securities traded over the counter (including 
long-term debt securities) are valued at the mean of the last bid and asked 
price if current market quotations are not readily available. Short-term debt 
securities which have a maturity date of more than sixty days will be valued 
at the mean of the last bid and asked price obtained from principal market 
makers. Short-term debt securities maturing in sixty days or less at the date 
of purchase will be valued using the "amortized cost" method of valuation. 
This involves valuing an instrument at its cost and thereafter assuming a 
constant amortization of premium or increase of discount. Long-term debt 
securities traded on a national securities exchange are valued at the mean of 
the last bid and asked price of such securities obtained from a broker 

26 Aetna Income Shares 
<PAGE>
 
who is a market-maker in the securities or a service providing quotations 
based upon the assessment of market-makers in those securities. 

Call options written by the Fund and put options are valued at the mean of 
the last bid and asked price on the principal exchange where the option is 
traded. Stock index futures contracts and interest rate futures contracts are 
valued daily at a settlement price based on rules of the exchange where the 
futures contract is primarily traded. The Trustees may authorize the use of 
independent pricing services, where appropriate.
