I. EXPENSE INFORMATION

   This table is designed to help you understand the charges and expenses
that you, as a shareholder, will bear directly or indirectly when you invest
in the Fund. The table reflects estimated expenses based on actual expenses
for the fiscal year ended December 31, 1994 expressed as a percentage of
average net assets of the Fund.
<TABLE>
<CAPTION>
<S>                                                      <C>
 Shareholder Transaction Expenses:
 Maximum Sales Charge on Purchases(1)                    5.75%
 Maximum Sales Charge on Reinvestment
    of Dividends                                         none
 Deferred Sales Charge(1)                                none
 Redemption Fee(2)                                       none
 Exchange Fee                                            none
Annual Operating Expenses (as a percentage of average
   net assets):
 Management Fee                                          0.45%
 12b-1 Fees                                              0.16%
 Other Expenses (including accounting,
    transfer agent and custody fees and
    printing expenses)                                   0.33%
                                                         ------
Total Operating Expenses                                 0.94%
                                                         ======
</TABLE>

(1) Purchases of $1,000,000 or more and purchases by participants in certain
    group plans are not subject to an initial sales charge. A contingent
    deferred sales charge of 1% may, however, be charged on redemptions by
    such accounts of shares held less than one year, as further described
    under "Redemptions and Repurchases."

(2) Separate fees (currently $10 and $20, respectively) apply to domestic or
    international bank wire transfers of redemption proceeds.

    Example:

   You would pay the following expenses on a $1,000 investment, assuming a 5%
annual return and constant expenses, with or without redemption at the end of
each time period:


 One Year     Three Years        Five Years       Ten Years
   $67             $86*              $107*           $166*

*These are cumulative totals; the average fees and expenses
 paid over a 10-year period would be approximately $16.60
 per year.

   The example above assumes reinvestment of all dividends and distributions
and that the percentage amounts listed under "Annual Operating Expenses"
remain the same each year.

   The example is designed for informational purposes only, and should not be
considered a representation of past or future expenses or return. Actual Fund
expenses and return vary from year to year and may be higher or lower than
those shown.

   
   For further information regarding management fees, 12b-1 fees and other
expenses of the Fund, see "Management of the Fund," "Distribution Plan" and
"How To Purchase Shares" in this Prospectus and "Management of the Fund" and
"Underwriting Agreement and Distribution Plan" in the Statement of Additional
Information. The Fund's payment of a 12b-1 fee may result in long-term
shareholders indirectly paying more than the economic equivalent of the
maximum sales charge permitted under the Rules of Fair Practice of the
National Association of Securities Dealers Inc. ("NASD").
    

   The maximum sales charge is reduced on purchases of specified amounts and
the value of shares owned in other Pioneer mutual funds is taken into account
in determining the applicable sales charge. See "How to Purchase Shares." No
sales charge is applied to exchanges of shares of the Fund for shares of
other publicly available Pioneer mutual funds. See "Exchange Privilege."

*Assumes initial investment at net asset value at the beginning of each year,
reinvestment of all dividends and distributions, and the complete redemption
of the investment at the net asset value at the end of each year and no sales
charges. Total return would be reduced if sales charges were taken into
account.

III. INVESTMENT OBJECTIVES AND POLICIES

   The investment objectives of the Fund are reasonable income and growth of
capital. The Fund seeks these objectives by investing in a broad list of
carefully selected, reasonably priced securities rather than investing in
securities whose prices reflect a premium from their current market
popularity. Most of the Fund's assets are invested in common stocks and other
equity securities such as preferred stocks and securities convertible into
common stock, but the Fund may also invest in debt securities and cash
equivalent investments.

   The largest portions of the Fund's portfolio are invested in securities
that have paid dividends within the preceding twelve months, but some
non-income producing securities are held for anticipated increases in value.
Assets of the Fund are substantially fully invested at all times because
management avoids speculating on broad changes in the level of the market.

   Whenever the Fund wishes to obtain funds not otherwise available for the
purchase of an attractive security, it pursues the policy of selling that
security in its portfolio which seems the least attractive security owned.
The resulting rate of turnover of the portfolio is not considered an
important factor. The Fund does not purchase and sell securities for
short-term profits; however, securities are sold without regard to the time
they have been held whenever selling seems advisable.

   The Fund may enter into repurchase agreements with banks, generally not
exceeding seven days. Such repurchase agreements will be fully collateralized
with United States ("U.S.") Treasury and/or Agency obligations with a market
value of not less than 100% of the obligation, valued daily. Collateral will
be held in a segregated, safekeeping account for the benefit of the Fund. In
the event that a repurchase agreement is not fulfilled, the Fund could suffer
a loss to the extent that the value of the collateral falls below the
repurchase price.

   The Fund may write (sell) covered call options in standard contracts
traded on national securities exchanges or those which may be quoted on the
Nasdaq market, provided that it continues to own the securities covering each
call until the call has been exercised or has expired, or until the Fund has
purchased a closing call to offset the obligation to deliver securities for
the call it has written. The Fund does not expect

                                      3

<PAGE>

to write (sell) covered call options with an aggregate market value exceeding
5% of the Fund's total assets in the foreseeable future. See the Statement of
Additional Information for information regarding the Fund's ability to write
(sell) covered call options.

   The Fund may invest in foreign securities if purchases of such securities
are otherwise consistent with the fundamental policies of the Fund. As a
matter of practice, however, the Fund does not invest in foreign securities
if there appears to be a substantial risk to the issuer of such securities of
nationalization, confiscation or other national restrictions. In connection
with its investments in foreign securities and in order to protect itself
against uncertainty in future exchange rates, the Fund may engage in foreign
currency exchange transactions.

   The foregoing objectives and policies may not be changed without
shareholder approval. Other investment policies and restrictions on
investments are described in the Statement of Additional Information
including a policy on lending portfolio securities. Among these other
investment policies and restrictions on investments, the Fund will not invest
more than 5% of its net assets in debt securities, including convertible
securities, which are rated less than investment grade or the equivalent.
Since all investments are subject to inherent market risks and fluctuations
in value due to earnings, economic conditions and other factors, the Fund, of
course, cannot assure that its investment objectives will be achieved.

IV. MANAGEMENT OF THE FUND

   The Fund's Board of Trustees has overall responsibility for management and
supervision of the Fund. There are currently eight Trustees of the Fund, six
of whom are not "interested persons" of the Fund as defined in the Investment
Company Act of 1940 (the "1940 Act"), as amended. The Board meets at least
quarterly. By virtue of the functions performed by Pioneering Management
Corporation ("PMC") as investment adviser, the Fund requires no employees
other than its executive officers, all of whom receive their compensation
from PMC or other sources. The Statement of Additional Information contains
the names of and general background information regarding each Trustee and
executive officer of the Fund.

   
The Fund is managed under a contract with PMC. PMC serves as investment
adviser to the Fund and is responsible for the overall management of the
Fund's business affairs, subject only to the authority of the Fund's Board of
Trustees. PMC is a wholly-owned subsidiary of The Pioneer Group, Inc. ("PGI"),
a Delaware corporation. PGI's indirect wholly-owned subsidiary, Pioneer Funds
Distributor, Inc. ("PFD"), is the principal underwriter of shares of the Fund.

   Each domestic equity portfolio managed by PMC, including the Fund, is
overseen by the Domestic Equity Portfolio Management Committee, which
consists of PMC's most senior domestic equity professionals. The Committee is
chaired by Mr. David Tripple, PMC's President and Chief Investment Officer
and Executive Vice President of each of the Funds. Mr. Tripple joined PMC in
1974 and has had general responsibility for PMC's investment operations and
specific portfolio assignments for over five years. Day-to-day management of
the Fund has been the responsibility of John A. Carey, Vice President of the
Fund and PMC, since February 1987. Mr. Carey joined PMC in 1979.
    

   In addition to the Fund, PMC also manages and serves as the investment
adviser for other mutual funds and is an investment adviser to certain other
institutional accounts. PMC's and PFD's executive offices are located at 60
State Street, Boston, Massachusetts 02109.

   Under the terms of its contract with the Fund, PMC assists in the
management of the Fund and is authorized in its discretion to buy and sell
securities for the account of the Fund. PMC pays all the ordinary operating
expenses, including executive salaries and the rental of office space
relating to its services for the Fund, with the exception of the following,
which are paid by the Fund: (a) taxes and other governmental charges, if any;
(b) interest on borrowed money, if any; (c) legal fees and expenses; (d)
auditing fees; (e) insurance premiums; (f) dues and fees for membership in
trade associations; (g) fees and expenses of registering and maintaining
registrations by the Fund of its shares with the SEC, individual states,
territories and foreign jurisdictions and of preparing reports to government
agencies; (h) fees and expenses of Trustees not affiliated with or interested
persons of PMC; (i) fees and expenses of the custodians, shareholder
servicing, dividend disbursing and transfer agent; (j) transfer taxes in
connection with securities transactions for the account of the Fund; (k)
costs of reports to shareholders, shareholders' meetings and Trustees'
meetings; (l) the cost of certificates representing shares of the Fund; (m)
bookkeeping and appraisal charges; and (n) distribution fees in accordance
with the Plan of Distribution described below. The Fund also pays all
brokers' and underwriting commissions chargeable to the Fund in connection
with its portfolio transactions.

   Orders for the Fund's portfolio securities transactions are placed by PMC,
which strives to obtain the best price and execution for each transaction. In
circumstances where two or more broker-dealers are in a position to offer
comparable prices and execution, consideration may be given to whether the
broker-dealer provides brokerage or research services or sells shares of the
Pioneer mutual funds. See the Statement of Additional Information for a
further description of PMC's brokerage allocation practices.

   As compensation for its management services and certain expenses which PMC
incurs, PMC is entitled to a management fee equal to 0.50% per annum of the
Fund's average daily net assets up to $250 million, 0.48% of the next $50
million and 0.45% of the excess over $300 million. The fee is normally
computed daily and paid monthly. During the fiscal year ended December 31,
1994, the Fund incurred expenses of approximately $19,421,000, including
management fees paid or payable to PMC of approximately $9,362,000.

   John F. Cogan, Jr., Chairman and President of the Fund, Chairman of PFD,
and President and a Director of PGI and Chairman of PMC, owned approximately
15% of the outstanding capital stock of PGI as of March 31, 1995.

V. DISTRIBUTION PLAN

   The Fund has adopted a Plan of Distribution (the "Plan") in accordance
with Rule 12b-1 under the 1940 Act pursuant to which certain distribution
fees are paid to PFD. As required by Rule 12b-1, the Plan was approved by a
majority of the outstanding shares held by the shareholders of the Fund and
by

                                      4

<PAGE>

the Trustees, including a majority of the Trustees who are not "interested
persons" of the Fund.

   Pursuant to the Plan, the Fund reimburses PFD for its actual expenditures
to finance any activity primarily intended to result in the sale of Fund
shares or to provide services to Fund shareholders, provided the categories
of expenses for which reimbursement is made are approved by the Fund's Board
of Trustees. As of the date of this Prospectus, the Board of Trustees has
approved the following categories of expenses for the Fund: (i) a service fee
to be paid to qualified broker-dealers in an amount not to exceed 0.25% per
annum of the Fund's daily net assets; (ii) reimbursement to PFD for its
expenditures for broker- dealer commissions and employee compensation on
certain sales of the Fund's shares with no initial sales charge (see "How to
Purchase Shares"); and (iii) reimbursement to PFD for expenses incurred in
providing services to shareholders and supporting broker-dealers and other
organizations (such as banks and trust companies) in their efforts to provide
such services. Banks are currently prohibited under the Glass-Steagall Act
from providing certain underwriting or distribution services. If a bank was
prohibited from acting in any capacity or providing any of the described
services, management would consider what action, if any, would be
appropriate.

   Expenditures of the Fund pursuant to the Plan are accrued daily and may
not exceed 0.25% of average daily net assets. Distribution expenses of PFD
are expected to substantially exceed the distribution fees paid by the Fund
in a given year. The Plan does not provide for the carryover of reimbursable
expenses beyond 12 months from the time the Fund is first invoiced for an
expense. The limited carryover provision in the Plan may result in an expense
invoiced to the Fund in one fiscal year being paid in the subsequent fiscal
year and thus being treated for purposes of calculating the maximum
expenditures of the Fund as having been incurred in the subsequent fiscal
year. In the event of termination or non-continuance of the Plan, the Fund
has 12 months to reimburse any expense which it incurs prior to such
termination or non-continuance, provided that payments by the Fund during
such 12-month period shall not exceed 0.25% of the Fund's average net daily
assets during such period. The Plan may not be amended to increase materially
the annual percentage limitation of average net assets which may be spent for
the services described therein without approval of the shareholders of the
Fund.

VI. INFORMATION ABOUT FUND SHARES

How to Purchase Shares

   You may purchase shares of the Fund at the public offering price from any
securities broker-dealer having a sales agreement with PFD. The minimum
initial investment is $50. Separate minimum investment requirements apply to
retirement plans and to telephone and wire orders placed by broker-dealers;
no sales charge or minimum investment requirements apply to the reinvestment
of dividends or capital gains distributions.

   The Fund has a minimum account requirement of $500. As a new purchaser,
you will be given at least 24 months from your initial purchase to increase
the value of the account to $500. See "Redemptions and Repurchases."

   
   Telephone Purchases. Your account is automatically authorized to have the
telephone purchase privilege unless you indicated otherwise on your Account
Application or by writing to Pioneering Services Corporation ("PSC"). The
telephone purchase option may be used to purchase additional shares for an
existing fund account; it may not be used to establish a new account. Proper
account identification will be required for each telephone purchase. A
maximum of $25,000 per account may be purchased by telephone each day. The
telephone purchase privilege is available to Individual Retirement Accounts
("IRAs") but may not be available to other types of retirement plan accounts.
Call PSC for more information.

   You are strongly urged to consult with your financial representative prior
to requesting a telephone purchase. To purchase shares by telephone, you must
establish your bank account of record by completing the appropriate section
of your Account Application or an Account Options Form. PSC will
electronically debit the amount of each purchase from this pre-designated
bank account. Telephone purchases may not be made for 30 days after the
establishment of your bank of record or any change to your bank information.

   Telephone purchases will be priced at the net asset value plus any
applicable sales charge next determined after PSC's acceptance of a telephone
purchase instruction and receipt of good funds (usually three days after the
purchase instruction). You may always elect to deliver purchases to PSC by
mail. See "Telephone Transactions and Related Liabilities" for additional
information.
    

   The public offering price is the net asset value per share next computed
after receipt of a purchase order, plus a sales charge as follows:

   No sales charge is payable at the time of purchase on investments of
$1,000,000 or more or on purchases by certain group plans ("Group Plans"),
but for such investments a contingent deferred sales charge ("CDSC") of 1% is
imposed in the event of certain redemption transactions within one year of
purchase. See "Redemptions and Repurchases" below. PFD may, in its
discretion, pay a commission to broker-dealers who initiate and are
responsible for such purchases as follows: 1% on the first $5 million
invested; 0.50% on the next $45 million; and 0.25% on the excess over $50
million. These commissions will not be paid if the purchaser is affiliated
with the broker-dealer or if the purchase represents the reinvestment of a
redemption made during the previous twelve calendar months. Broker-dealers
who receive a commission in connection with purchases at net asset value by
401(a) or 401(k) retirement plans with 1,000 or more eligible participants or
with at least $10 million in plan assets
    


                                      5

<PAGE>

will be required to return any commission paid or a pro rata portion thereof
if the retirement plan redeems its shares within 12 months of purchase. See
also "Redemptions and Repurchases." In connection with PGI's acquisition of
Mutual of Omaha Fund Management Company and contingent upon the achievement
of certain sales objectives, PFD pays to Mutual of Omaha Investor Services,
Inc. 50% of PFD's retention of any sales commission on sales of the Fund's
shares through such dealer. Shares sold outside the U.S. to persons who are
not U.S. citizens may be subject to different sales charges, CDSCs and dealer
compensation arrangements in accordance with local laws and business
practices.

   The schedule of sales charges above is applicable to purchases of shares
of the Fund by (i) an individual, (ii) an individual, his or her spouse and
children under the age of 21 and (iii) a trustee or other fiduciary of a
trust estate or fiduciary account or related trusts or accounts including
pension, profit-sharing and other employee benefit trusts qualified under
Section 401 or 408 of the Internal Revenue Code of 1986, as amended (the
"Code"), although more than one beneficiary is involved.

   
   The sales charge applicable to a current purchase of shares of the Fund by
a person listed above is determined by adding the value of shares to be
purchased to the aggregate value (at current offering price) of shares of any
of the other Pioneer mutual funds previously purchased and then owned,
provided PFD is notified by such person or his or her broker-dealer each time
a purchase is made which would qualify. Pioneer mutual funds include all
mutual funds for which PFD serves as principal underwriter. For example, a
person investing $5,000 in the Fund who currently owns shares of other
Pioneer mutual funds with a value of $45,000 would pay a sales charge of
4.50% of the offering price of the new investment.
    

   Sales charges may also be reduced through an agreement to purchase a
specified quantity of shares over a designated 13-month period by completing
the "Letter of Intention" section of the Account Application. Information
about the Letter of Intention procedure, including its terms, is contained in
the Account Application as well as in the Statement of Additional
Information.

   Shares of the Fund may be sold at a reduced or eliminated sales charge to
certain Group Plans under which a sponsoring organization makes
recommendations to, permits group solicitation of, or otherwise facilitates
purchases by, its employees, members or participants. Shares of the Fund may
be sold at net asset value per share without a sales charge to Optional
Retirement Program participants if (i) the employer has authorized a limited
number of investment company providers for the Program, (ii) all authorized
investment company providers offer their shares to Program participants at
net asset value, (iii) the employer has agreed in writing to actively promote
the authorized investment providers to Program participants and (iv) the
Program provides for a matching contribution for each participant
contribution. Information about such arrangements is available from PFD.

   Shares of the Fund may also be sold at net asset value per share without a
sales charge to: (a) current or former Trustees and officers of the Fund and
partners and employees of its legal counsel; (b) current or former directors,
officers, employees or sales representatives of PGI or its subsidiaries; (c)
current or former directors, officers, employees or sales representatives of
any subadviser or predecessor investment adviser to any investment company
for which PMC serves as investment adviser, and the subsidiaries or
affiliates of such persons; (d) current or former officers, partners,
employees or registered representatives of broker-dealers which have entered
into sales agreements with PFD; (e) members of the immediate families of any
of the persons above; (f) any trust, custodian, pension, profit-sharing or
other benefit plan of the foregoing persons; (g) insurance company separate
accounts; (h) certain "wrap accounts" for the benefit of clients of financial
planners adhering to standards established by PFD; (i) other funds and
accounts for which PMC or any of its affiliates serves as investment adviser
or manager; and (j) certain unit investment trusts. Shares so purchased are
purchased for investment purposes only and may not be resold except through
redemption or repurchase by or on behalf of the Fund. The availability of
this privilege depends upon the receipt by PFD of written notification of
eligibility. Shares of the Fund may also be sold at net asset value without a
sales charge in connection with certain reorganization, liquidation or
acquisition transactions involving other investment companies or personal
holding companies.

   Investors who are clients of a broker-dealer with a current sales
agreement with PFD may purchase shares of the Fund at net asset value,
without a sales charge, to the extent that the purchase price is paid out of
proceeds from one or more redemptions by the investor of shares of certain
other mutual funds. In order for a purchase to qualify for this privilege,
the investor must document to the broker-dealer that the redemption occurred
within 60 days immediately preceding the purchase of shares of the Fund; that
the client paid a sales charge on the original purchase of the shares
redeemed; and that the mutual fund whose shares were redeemed also offers net
asset value purchases to redeeming shareholders of any of the Pioneer mutual
funds. Further details may be obtained from PFD.

Net Asset Value and Pricing of Orders

   Shares of the Fund are sold at the public offering price, which is the net
asset value per share plus the applicable sales charge. Net asset value per
share of the Fund is determined by dividing the value of its assets, less
liabilities, by the number of shares outstanding. The net asset value is
computed once daily, on each day the New York Stock Exchange (the "Exchange")
is open, as of the close of regular trading on the Exchange.

   Securities are valued at the last sale price on the principal exchange or
market where they are traded. Securities which have not traded on the date of
valuation or securities for which sales prices are not generally reported are
valued at the mean between the current bid and asked prices. Securities
quoted in foreign currencies are converted to U.S. dollars utilizing foreign
exchange rates employed by the Fund's independent pricing services.
Generally, trading in foreign securities is substantially completed each day
at various times prior to the close of regular trading on the Exchange. The
values of such securities used in computing the net asset value

                                      6

<PAGE>

of the Fund's shares are determined as of such times. Foreign currency
exchange rates are also generally determined prior to the close of regular
trading on the Exchange. Occasionally, events which affect the values of such
securities and such exchange rates may occur between the times at which they
are determined and the close of regular trading on the Exchange and will
therefore not be reflected in the computation of the Fund's net asset value.
If events materially affecting the value of such securities occur during such
period, then these securities are valued at their fair value as determined in
good faith by the Trustees. All assets of the Fund for which there is no
other readily available valuation method are valued at their fair value as
determined in good faith by the Trustees.

   An order for shares received by a broker-dealer prior to the close of
regular trading on the Exchange (currently 4:00 p.m. Eastern Time) is
confirmed at the redemption price determined at the close of regular trading
on the Exchange on the day the order is received, provided the order is
received by PFD prior to PFD's close of business (usually 5:30 p.m. Eastern
Time). It is the responsibility of broker-dealers to transmit orders so that
they will be received by PFD prior to PFD's close of business. An order
received by a broker-dealer following the close of regular trading on the
Exchange will be confirmed at the offering price as of the close of regular
trading on the Exchange on the next trading day.

   The Fund reserves the right in its sole discretion to withdraw all or any
part of the offering of shares when, in the judgment of the Fund's
management, such withdrawal is in the best interest of the Fund. An order to
purchase shares is not binding on, and may be rejected by, PFD until it has
been confirmed in writing by PFD and payment has been received.

Dividends, Distributions and Taxation

   The Fund has elected to be treated, has qualified, and intends to qualify
each year as a "regulated investment company" under the Code, so that it will
not pay federal income taxes on income and capital gains distributed to
shareholders at least annually.

   Under the Code, the Fund will be subject to a nondeductible 4% federal
excise tax on a portion of its undistributed ordinary income and capital
gains if it fails to meet certain distribution requirements with respect to
each calendar year. The Fund intends to make distributions in a timely manner
and accordingly does not expect to be subject to the excise tax.

   The Fund's policy is to pay to shareholders dividends from net investment
income, if any, quarterly during the months of March, June, September and
December and to make distributions from net long term capital gains, if any,
in December. Distributions from net short-term capital gains, if any, may be
paid with such dividends, and other distributions from income and/or capital
gains may also be made at such times as may be necessary to avoid federal
income or excise tax. Dividends from the Fund's net investment income, net
short-term capital gains and certain net foreign exchange gains are taxable
as ordinary income. Dividends from the Fund's net long-term capital gains are
taxable as long-term capital gains.

   Unless shareholders specify otherwise, all distributions will be
automatically reinvested in additional full and fractional shares of the
Fund. For federal income tax purposes, all distributions are taxable as
described above whether a shareholder takes them in cash or reinvests them in
additional shares of the Fund. Information as to the federal tax status of
distributions will be provided to shareholders annually. For further
information on the distribution options available to shareholders, see
"Distribution Options" and "Directed Dividends" below.

   Distributions by the Fund of dividend income it receives from U.S.
domestic corporations may qualify for the dividends-received deduction for
corporate shareholders, subject to certain minimum holding period
requirements and debt-financing restrictions under the Code.

   
   Dividends and other distributions and the proceeds of redemptions,
exchanges or repurchases of Fund shares paid to individuals and other
non-exempt payees will be subject to a 31% backup withholding of federal
income tax if the Fund is not provided with the shareholder's correct
taxpayer identification number and certification that the number is correct
and that the shareholder is not subject to such backup withholding or if the
Fund receives notice from the Internal Revenue Service ("IRS") or a broker
that such withholding applies. Please refer to the Account Application for
additional information.
    

   The description above relates only to U.S. federal income tax consequences
for shareholders who are U.S. persons, i.e. U.S. citizens or residents, or
U.S. corporations, partnerships, trusts or estates and who are subject to
U.S. federal income tax. Non-U.S. shareholders and tax-exempt shareholders
are subject to different tax treatment that is not described above. You
should consult your own tax adviser regarding state, local and other
applicable tax laws.

Redemptions and Repurchases

   
   Redemptions by Mail. As a shareholder, you have the right to offer your
shares for redemption by delivering to PSC a written request for redemption
in proper form, signed by all registered owners, and your share certificates,
if any, properly endorsed and in good order for transfer. Redemptions will be
made in cash at the net asset value per share next determined following
receipt by PSC of all necessary documents subject in certain cases to the
CDSC described below.
    

   Good order means that there are no outstanding claims or requests to hold
redemptions on the account, any certificates are endorsed by the record
owner(s) exactly as the shares are registered and the signature(s) are
guaranteed by any of the following eligible guarantor institutions: (i) all
brokers, dealers, municipal securities dealers and/or brokers and government
securities dealers and/or brokers who are members of a clearing agency or
whose net capital exceeds $100,000; (ii) all banks; (iii) all credit unions;
(iv) all savings associations, including all savings and loan associations;
(v) all national securities exchanges, registered securities associations,
and all clearing agencies; and (vi) all trust companies. In addition, in some
cases (involving fiduciary or corporate transactions), good order may require
the furnishing of additional documents.

   Signature guarantees may be waived for redemption requests of $50,000 or
less, provided that the record holder executes the redemption request,
payment is directed to the

                                      7

<PAGE>

record holder at the address of record, and the address has not changed in
the previous 30 days. You cannot provide a signature guarantee by facsimile
("fax"). Payment normally will be made within seven days after receipt of
these documents. The Fund reserves the right to withhold payment until checks
received in payment of shares purchased have cleared, which may take up to 15
calendar days from the purchase date. For additional information about the
necessary documentation for redemption by mail, call PSC at 1-800-225-6292.

   
   Redemption by Telephone or Fax. Your account is automatically authorized
to have the telephone redemption privilege unless you indicated otherwise on
your Account Application or by writing to PSC. Proper account identification
will be required for each telephone redemption. The telephone redemption
option is not available to retirement plan accounts. A maximum of $50,000 may
be redeemed by telephone or fax and the proceeds may be received by check or
by bank wire or electronic funds transfer. To receive the proceeds by check:
the check must be made payable exactly as the account is registered and the
check must be sent to the address of record which must not have changed in
the last 30 days. To receive the proceeds by bank wire or by electronic funds
transfer: the proceeds must be sent to your bank address of record which must
have been properly pre-designated either on your Account Application or on an
Account Options Form and which must not have changed in the last 30 days. To
redeem by fax, send your redemption request to 1-800-225-4240. You may always
elect to deliver redemption instructions to PSC by mail. See "Telephone
Transactions and Related Liabilities" below. Telephone redemptions will be
priced as described above. You are strongly urged to consult with your
financial representative prior to requesting a telephone redemption.
    

   Sales of Shares Through Broker-Dealers. For the convenience of
shareholders, the Fund has authorized PFD to act as its agent in the
repurchase of shares of the Fund from qualified broker-dealers. The Fund
reserves the right to terminate this procedure at any time. Offers to sell
shares to the Fund may be communicated to PFD by wire or telephone by
broker-dealers for their customers. The Fund's practice will be to repurchase
shares offered to it at the net asset value per share determined as of the
close of business of the Exchange on the day the offer for repurchase is
received and accepted by the broker-dealer if the offer is received by PFD
before the close of business on that day.

   A broker-dealer which receives an offer for repurchase is responsible for
the prompt transmittal of such offer to PFD. Payment of the repurchase
proceeds will be made in cash to the broker-dealer placing the order. Except
for certain large accounts subject to a CDSC (as described below), neither
the Fund nor PFD charges any fee or commission upon such repurchase which is
then settled as an ordinary transaction with the broker-dealer (which may
charge the shareholder for this service) delivering the shares repurchased.
Payment will be made within seven days of the receipt by PSC of valid
instructions, including validly endorsed certificates, if appropriate, in
good order as described above.

   Additional Conditions of Redemption. The net asset value per share
received upon redemption or repurchase may be more or less than the cost of
shares to an investor, depending upon the market value of the portfolio at
the time of redemption or repurchase. Redemptions and repurchases are taxable
transactions to shareholders. Shareholders whose accounts are registered in
the name of a broker, dealer or other financial institution must contact a
representative of the institution holding the shares to arrange for a
redemption.

   Redemptions may be suspended or payment postponed during any period in
which any of the following conditions exists: the Exchange is closed or
trading on the Exchange is restricted; an emergency exists as a result of
which disposal by the Fund of securities owned by it is not reasonably
practicable or it is not reasonably practicable for the Fund to fairly
determine the value of the net assets of its portfolio; or the SEC, by order,
so permits.

   Purchases of $1,000,000 or more, and purchases by participants in a Group
Plan which have not been subject to a sales charge, may be subject to a CDSC
upon redemption or repurchase. A CDSC is payable on these investments in the
event of a share redemption within 12 months following the share purchase, at
the rate of 1% of the lesser of the value of the shares redeemed (exclusive
of reinvested dividend and capital gain distributions) or the total cost of
such shares. In determining whether a CDSC is payable, and, if so, the amount
of the CDSC, it is assumed that shares purchased with reinvested dividend and
capital gain distributions and then such other shares which are held the
longest will be the first redeemed. Shares subject to the CDSC which are
exchanged into another Pioneer mutual fund will continue to be subject to the
CDSC until the original 12-month period expires. See "Exchange Privilege" for
more information. However, no CDSC is payable with respect to purchases of
shares by 401(a) or 401(k) retirement plans with 1,000 or more eligible
participants or with at least $10 million in plan assets.

   Waiver or Reduction of Contingent Deferred Sales Charge. The CDSC on
shares subject to a CDSC may be waived or reduced for non-retirement accounts
if: (a) the redemption results from the death of all registered owners of an
account (in the case of UGMAs, UTMAs and trust accounts, waiver applies upon
the death of all beneficial owners) or a total and permanent disability (as
defined in Section 72 of the Code) of all registered owners occurring after
the purchase of the shares being redeemed or (b) the redemption is made in
connection with limited automatic redemptions as set forth in "Systematic
Withdrawal Plans" (limited in any year to 10% of the value of the account in
the Fund at the time the withdrawal plan is established).

   The CDSC on shares subject to a CDSC may be waived or reduced for
retirement plan accounts if: (a) the redemption results from the death or a
total and permanent disability (as defined in Section 72 of the Code)
occurring after the purchase of the shares being redeemed of a shareholder or
participant in an employer-sponsored retirement plan; (b) the distribution is
to a participant in an IRA, 403(b) or employer-sponsored retirement plan, is
part of a series of substantially equal payments made over the life
expectancy of the participant or the joint life expectancy of the participant
and his or her beneficiary or as scheduled periodic payments to a participant
(limited in any year to 10% of the value of the participant's account at the
time

                                      8

<PAGE>

the distribution amount is established; a required minimum distribution due
to the participant's attainment of age 70-1/2 may exceed the 10% limit only
if the distribution amount is based on plan assets held by Pioneer); (c) the
distribution is from a 401(a) or 401(k) retirement plan and is a return of
excess employee deferrals or employee contributions or a qualifying hardship
distribution as defined by the Code or results from a termination of
employment (limited with respect to a termination to 10% per year of the
value of the plan's assets in the Fund as of the later of the prior December
31 or the date the account was established unless the plan's assets are being
rolled over to or reinvested in the same class of shares of a Pioneer mutual
fund subject to the CDSC of the shares originally held); (d) the distribution
is from an IRA, 403(b) or employer-sponsored retirement plan and is to be
rolled over to or reinvested in the same class of shares in a Pioneer mutual
fund and which will be subject to the applicable CDSC upon redemption; (e)
the distribution is in the form of a loan to a participant in a plan which
permits loans (each repayment of the loan will constitute a new sale which
will be subject to the applicable CDSC upon redemption); or (f) the
distribution is from a qualified defined contribution plan and represents a
participant's directed transfer (provided that this privilege has been
pre-authorized through a prior agreement with PFD regarding participant
directed transfers).

   The CDSC on shares subject to a CDSC may be waived or reduced for either
non-retirement or retirement plan accounts if: (a) the redemption is made by
any state, county, or city, or any instrumentality, department, authority, or
agency thereof, which is prohibited by applicable laws from paying a CDSC in
connection with the acquisition of shares of any registered investment
management company; or (b) the redemption is made pursuant to the Fund's
right to liquidate or involuntarily redeem shares in a shareholder's account.

Redemption of Small Accounts

   As a new shareholder, you have a minimum of 24 months (including the six
months following the mailing of the notice described below) to increase the
value of your account to $500 or more. If you hold shares of the Fund in an
account with a net asset value of less than $500 due to redemptions or
exchanges or failure to meet the initial minimum account requirement set
forth above, the Fund may redeem the shares held in this account at net asset
value if you have not increased the net asset value of the account to at
least $500 within six months of written notice by the Fund to you of the
Fund's intention to redeem the shares.

Description of Shares and Voting Rights

   The Fund is an open-end diversified management investment company
(commonly referred to as a mutual fund) which was organized as a Delaware
corporation in 1928 and reorganized as a Massachusetts corporation in 1967
and as a Massachusetts business trust in 1985. The Fund has authorized an
unlimited number of shares of beneficial interest. As an open-end investment
company, the Fund continuously offers its shares to the public and under
normal conditions must redeem its shares upon the demand of any shareholder
at the then current net asset value per share. See "Redemptions and
Repurchases" above.

   The Fund has only one class of shares, entitled shares of beneficial
interest. Each share represents an equal proportionate interest in the Fund
with each other share. Shareholders are entitled to one vote for each share
held and may vote in the election and removal of Trustees and on other
matters submitted to shareholders. Shares have no preemptive or conversion
rights. Shares are fully-paid and, except as set forth in the Statement of
Additional Information, non-assessable. Upon liquidation of the Fund, the
Fund's shareholders would be entitled to share pro rata in the Fund's net
assets available for distribution. Shares will remain on deposit with PSC and
certificates will not be issued unless requested. Certificates for fractional
shares will not be issued. The Fund reserves the right to charge a fee for
the issuance of certificates.

   The Fund reserves the right to create and issue additional series of
shares, in which case the shares of each series would participate equally in
the earnings, dividends and assets of the particular series. Shares of each
series would be entitled to vote separately to approve investment advisory
agreements or changes in investment restrictions, but shares of all series
would be entitled to vote together in the election or selection of Trustees
and accountants.

VII. SHAREHOLDER SERVICES

   PSC is the shareholder services and transfer agent for shares of the Fund.
PSC, a Massachusetts corporation, is a wholly-owned subsidiary of PGI. PSC's
offices are located at 60 State Street, Boston, Massachusetts 02109, and
inquiries to PSC should be mailed to Shareholder Services, Pioneering
Services Corporation, P.O. Box 9014, Boston, Massachusetts 02205-9014. Brown
Brothers Harriman & Co. ("the Custodian") serves as custodian of the Fund's
portfolio securities. The principal business address of the mutual fund
division of the Custodian is 40 Water Street, Boston, Massachusetts 02109.

Account and Confirmation Statements

   PSC maintains an account for each shareholder and all transactions of the
shareholder are recorded in this account. Confirmation statements showing the
details of transactions are sent to shareholders as transactions occur,
except Automatic Investment Plan transactions which are confirmed quarterly.
The Pioneer Combined Account Statement, mailed quarterly, is available to all
shareholders who have more than one Pioneer account.

   Shareholders whose shares are held in the name of an investment
broker-dealer or other party will not normally have an account with the Fund
and might not be able to utilize some of the services available to
shareholders of record. Examples of services which might not be available are
investment or redemption of shares by mail, automatic reinvestment of
dividends and capital gains distributions, withdrawal plans, Letters of
Intention, Rights of Accumulation, telephone exchanges and redemptions,
newsletters and other informational mailings.

Additional Investments

   You may add to your account by sending a check ($50 minimum) to PSC
(account number should be clearly indicated). The bottom portion of a
confirmation statement may be used as a remittance slip to make additional
investments. Additions to your account, whether by check or through a Pioneer
Investomatic Plan, are invested in full and fractional shares of the Fund at
the applicable offering price in effect as of the close of regular trading on
the Exchange on the day of receipt.

                                      9

<PAGE>

Automatic Investment Plans

   You may arrange for regular automatic investments of $50 or more through
government/military allotments or through a Pioneer Investomatic Plan. A
Pioneer Investomatic Plan provides for a monthly or quarterly investment by
means of a preauthorized draft drawn on a checking account. Pioneer
Investomatic Plan investments are voluntary and you may discontinue the plan
without penalty upon 30 days' written notice to PSC. PSC acts as agent for
the purchaser, the broker-dealer, and PFD in maintaining these plans.

Financial Reports and Tax Information

   As a shareholder, you will receive financial reports at least
semi-annually. In January of each year, the Fund will mail you information
about the tax status of dividends and other distributions.

Distribution Options

   Dividends and capital gains distributions, if any, will automatically be
invested in additional shares of the Fund, at the applicable net asset value
per share, unless you indicate another option on the Account Application.

   Two other available options are (a) dividends in cash and capital gains
distributions in additional shares; and (b) all dividends and distributions
in cash. These two options are not available, however, for retirement plans
or an account with a net asset value of less than $500. Changes in the
distribution options may be made by written request to PSC.

Directed Dividends

   You may elect (in writing) to have the dividends paid by one Pioneer fund
account invested in a second Pioneer mutual fund account. The value of this
second account must be at least $1,000 ($500 for the Fund or Pioneer II).
Invested dividends may be in any amount, and there are no fees or charges for
this service. Retirement plan shareholders may only direct dividends to
accounts with identical registrations i.e., PGI IRA Cust for John Smith may
only go into another account registered PGI IRA Cust for John Smith.

Direct Deposit

   If you have elected to take distributions, whether dividends or dividends
and capital gains, in cash, or have established a Systematic Withdrawal Plan,
you may choose to have those cash payments deposited directly into your
savings, checking or NOW bank account. You may establish this service by
completing the appropriate section on the Account Application when opening a
new account or the Account Options Form for an existing account.

Voluntary Tax Withholding

   
   You may request (in writing) that PSC withhold 28% of the dividends and
capital gains distribution paid from your account (before any reinvestment)
and forward the amount withheld to the IRS as a credit against your federal
income taxes. This option is not available for retirement plan accounts or
for accounts subject to backup withholding.
    

Exchange Privilege

   Exchanges must be at least $1,000. You may exchange your shares of the
Fund at net asset value, without a sales charge, for shares of other Pioneer
mutual funds which do not offer different classes of shares or for the Class
A shares of those Pioneer mutual funds that offer more than one class of
shares. There are currently no fees or sales charges on such an exchange. An
exchange of shares may be made only in states where legally permitted.

   
   A new Pioneer mutual fund account opened through an exchange must have a
registration identical to that on the original account. PSC will process
exchanges only after receiving an exchange request in proper form.
    

    Written Exchanges. If the exchange request is in writing, it must be
signed by all record owner(s) exactly as the shares are registered. If your
original account includes a Pioneer Investomatic or Systematic Withdrawal
Plan and you open a new account by exchange, you should specify whether the
plans should continue in your new account or remain with your original
account.

   
    Telephone Exchanges. Your account is automatically authorized to have the
telephone exchange privilege unless you indicated otherwise on your Account
Application or by writing to PSC. Proper account identification will be
required for each telephone exchange. Telephone exchanges may not exceed
$500,000 per account per day. Each telephone exchange request, whether by
voice or by FactFone, will be recorded. You are strongly urged to consult
with your financial representative prior to requesting a telephone exchange.

    Automatic Exchange. You may automatically exchange shares from one
Pioneer mutual fund account to another Pioneer mutual fund account on a
regular schedule, either monthly or quarterly. The accounts must have
identical registrations and the originating account must have a minimum
balance of $5,000. The exchange will occur on the 18th day of each month.
    

   If an exchange request is received by PSC before 4:00 p.m. Eastern Time
(or before the time that the Exchange closes for regular trading on that day,
if different), the exchange will be effective on that day if the requirements
above have been met. If the exchange request is received after this time, the
exchange will be effective on the following business day.

   You should consider the differences in objectives and policies of the
Pioneer mutual funds, as described in each fund's current prospectus, before
making any exchange. For federal and (generally) state income tax purposes,
an exchange represents a sale of the shares exchanged and a purchase of
shares in another fund. Therefore, an exchange could result in a gain or loss
on the shares sold, depending on the tax basis of these shares and the timing
of the transaction, and special tax rules may apply.

   To prevent abuse of the exchange privilege to the detriment of other Fund
shareholders, the Fund and PFD reserve the right to limit the number and/or
frequency of exchanges and/or to charge a fee for exchanges.

Telephone Transactions and Related Liabilities

   
   Your account is automatically authorized to have telephone transaction
privileges unless you indicated otherwise on your Account Application or by
writing to PSC. You may purchase, sell or exchange Fund shares by telephone.
See "Net Asset Value and Pricing of Orders" for more information. For
personal assistance, call 1-800-225-6292 between 8:00 a.m. and 8:00 p.m.

                                      10

<PAGE>

Eastern Time on weekdays. Computer-assisted transactions may be available to
shareholders who have pre-recorded certain bank information (see
"FactFone(SM)"). You are strongly urged to consult with your financial
representative prior to requesting any telephone transaction. See "Net Asset
Value and Pricing of Orders," "Redemptions and Repurchases" and "Exchange
Privilege" for more information. To confirm that each transaction instruction
received by telephone is genuine, PSC will record each telephone transaction,
require the caller to provide the personal identification number ("PIN") for
the account and send you a written confirmation of each telephone
transaction. Different procedures may apply to accounts that are registered
to non-U.S. citizens or that are held in the name of an institution or in the
name of an investment broker-dealer or other third-party. If reasonable
procedures, such as those described above, are not followed, the Fund may be
liable for any loss due to unauthorized or fraudulent instructions. The Fund
may implement other procedures from time to time. In all other cases, neither
the Fund, PSC or PFD will be responsible for the authenticity of instructions
received by telephone, therefore, you bear the risk of loss for unauthorized
or fraudulent telephone transactions.

   During times of economic turmoil or market volatility or as a result of
severe weather or a natural disaster, it may be difficult to contact the Fund
by telephone to institute a redemption or exchange. You should communicate
with the Fund in writing if you are unable to reach the Fund by telephone.


FactFone(SM)

   FactFone is an automated inquiry and telephone transaction system
available to Pioneer shareholders by dialing 1-800-225-4321. FactFone allows
you to obtain current information on your Pioneer mutual fund accounts and to
inquire about the prices and yields of all publicly available Pioneer mutual
funds. In addition, you may use FactFone to make computer-assisted telephone
purchases, exchanges and redemptions from your Pioneer accounts if you have
activated your PIN. Telephone purchases and redemptions require the
establishment of a bank account of record. You are strongly urged to consult
with your financial representative prior to requesting any telephone
transaction. Shareholders whose accounts are registered in the name of a
broker-dealer or other thrid party may not be able to use FactFone. See "How
to Purchase Fund Shares," "Exchange Privilege," "Redemptions and Repurchases"
and "Telephone Transactions and Related Liabilities." Call PSC for
assistance.
    

Telecommunications Device for the Deaf (TDD)

   If you have a hearing disability and your own TDD keyboard equipment, you
can call our TDD number toll-free at 1-800- 225-1997, weekdays from 8:30 a.m.
to 5:30 p.m. Eastern Time, to contact our telephone representatives with
questions about your account.

Retirement Plans

   
   You should contact the Retirement Plans Department of PSC at
1-800-622-0176 for information on retirement plans for businesses, Simplified
Employee Pensions Plans, IRAs, and Section 403(b) retirement plans for
employees of certain non-profit organizations and public school systems, all
of which are available in conjunction with investments in the Fund. The
Account Application accompanying this Prospectus should not be used to
establish any of these plans. Separate applications are required.
    

Systematic Withdrawal Plans

   
   If your account has a total value of at least $10,000, you may establish a
Systematic Withdrawal Plan ("SWP") providing for fixed payments at regular
intervals. Periodic checks of $50 or more will be sent to you monthly or
quarterly and your periodic redemptions of shares may be taxable to you. You
may also direct that withdrawal checks be paid to another person, although if
you make this designation after you have opened your account, a signature
guarantee must accompany your instructions. Purchases of shares of the Fund
at a time when you have a SWP in effect may result in the payment of
unnecessary sales charges and may therefore be disadvantageous.
    

   You may obtain additional information by calling PSC at 1-800-225-6292 or
by referring to the Statement of Additional Information.

Reinstatement Privilege

   If you redeem all or part of your shares of the Fund, you may reinvest all
or part of the redemption proceeds without a sales commission in shares of
the Fund if you send a written request to PSC not more than 90 days after
your shares were redeemed. Your redemption proceeds will be reinvested at the
next determined net asset value of the shares of the Fund after receipt of
the written request for reinstatement. You may realize a gain or loss for
federal income tax purposes as a result of the redemption, and special tax
rules may apply if a reinstatement occurs. Subject to the provisions outlined
under "Exchange Privilege" above, you may also reinvest in any other Pioneer
mutual funds; in this case you must meet the minimum investment requirement
for each fund you enter.

   The 90-day reinstatement period may be extended by PFD for periods of up
to one year for shareholders living in areas that have experienced a natural
disaster, such as a flood, hurricane, tornado, or earthquake.

   The options and services available to shareholders, including the terms of
the Exchange Privilege and the Pioneer Investomatic Plan, may be revised,
suspended, or terminated at any time by PFD or by the Fund. You may establish
the services described in this section when you open your account. You may
also establish or revise many of them on an existing account by filling out
an Account Options Form, which you may request by calling 1-800-225-6292.

VIII. INVESTMENT RESULTS

   The Fund may include in advertisements, and furnish to existing or
prospective shareholders, information concerning the average annual total
return on an investment in the Fund for a designated period of time. Whenever
this information is provided, it includes a standardized calculation of
average annual total return computed by determining the average annual
compounded rate of return that would cause a hypothetical investment (after
deduction of the maximum sales charge) made on the first day of the
designated period

                                      11

<PAGE>

(assuming all dividends and distributions are reinvested) to equal the
resulting net asset value of such hypothetical investment on the last day of
the designated period. The periods illustrated would normally include one,
five and ten years. These standardized calculations do not reflect the impact
of federal or state income taxes.

   The foregoing computation method is prescribed for advertising and other
communications subject to SEC Rule 482. Communications not subject to this
rule may contain one or more additional measures of investment results,
computation methods and assumptions, including but not limited to: historical
total returns; distribution returns; results of actual or hypothetical
investments; changes in dividends, distributions or share values; or any
graphic illustration of such data. These data may cover any period of the
Fund's existence and may or may not include the impact of sales charges,
taxes or other factors.

   Other investments or savings vehicles and/or unmanaged market indexes,
indicators of economic activity, or averages of mutual funds results may be
cited or compared with the investment results of the Fund. Rankings or
listings by magazines, newspapers or independent statistical or ratings
services, such as Lipper Analytical Services, Inc. or Ibbotson Associates,
may also be referenced.

   The Fund's investment results will vary from time to time depending on
market conditions, the composition of the Fund's portfolio and operating
expenses of the Fund. Therefore, any prior investment results of the Fund
should not be considered representative of what an investment in the Fund may
earn in any future period. These factors and possible differences in the
methods used in calculating investment results should be considered when
comparing performance information regarding the Fund to information published
for other investment companies, investment vehicles, and unmanaged indexes.
The Fund's investment results should also be considered relative to the risks
associated with the Fund's investment objectives and policies.

   For further information about the calculation methods used for computing
the Fund's investment results, see the Statement of Additional Information.

        THIS STATEMENT OF ADDITIONAL INFORMATION IS NOT A PROSPECTUS AND
         IS AUTHORIZED FOR DISTRIBUTION TO PROSPECTIVE INVESTORS ONLY IF
               PRECEDED OR ACCOMPANIED BY AN EFFECTIVE PROSPECTUS.


<PAGE>

         1. INVESTMENT POLICIES AND RESTRICTIONS

         The  Prospectus of Pioneer Fund (the "Fund")  identifies the investment
objectives and the principal  investment  policies of the Fund. Other investment
policies of the Fund are set forth below.

         Lending of Portfolio Securities

         In order to realize  additional income, the Fund may lend its portfolio
securities, principally to broker-dealers,  under agreements which would require
that the loans be secured  continuously  by cash  equivalents  or United  States
("U.S.")  Treasury  bills equal at all times to at least the market value of the
securities  loaned.  The Fund would continue to receive interest or dividends on
the securities loaned and would also earn interest on the investment of the loan
collateral.  The loan collateral would be invested only in U.S.  Treasury notes,
certificates  of  deposit  or  other  high-grade,   short-term   obligations  or
interest-bearing cash equivalents.  Although voting rights, or rights to consent
attendant to securities loaned, pass to the borrower,  such loans will be called
so that the securities may be voted if a material event affecting the investment
is to occur.

         As with  other  extensions  of  credit,  there  are  risks  of delay in
recovery  or even loss of rights in the  collateral  should the  borrower of the
securities  fail  financially.  The Fund will lend portfolio  securities only to
firms which have been approved in advance by the Fund's Board of Trustees, which
will monitor the  creditworthiness  of any such firms.  If the management of the
Fund  decides to make  securities  loans,  it is intended  that the value of the
securities  loaned by the Fund  would not  exceed 30% of the value of the Fund's
total  assets.  In the  Fund's  last  fiscal  year,  it did not  lend  portfolio
securities  with a value  exceeding 5% of its net assets and,  while it reserves
the right to do so,  the Fund has no  present  intention  of  lending  portfolio
securities with such a value during the coming year.

         Covered Call Options

         The Fund may write (sell)  covered  call  options on certain  portfolio
securities,  but  options  may not be written on more than 25% of the  aggregate
market value of any single  portfolio  security  (determined each time a call is
sold as of the  date of such  sale).  As  writers  of a call  option,  the  Fund
receives a premium less commission,  and, in exchange,  foregoes the opportunity
to profit from  increases in the market value of the security  covering the call
above the sum of the premium  and the  exercise  price of the option  during the
life of the option.  The  purchaser of such a call has the option of  purchasing
the  security  from the Fund's  portfolio at the option price during the life of
the option.  Portfolio  securities on which options may be written are purchased
solely on the basis of  investment  considerations  consistent  with the  Fund's
investment  objectives.  The  security  covering  the  call is  maintained  in a
segregated  account  of the  Fund's  custodian.  The Fund  does not  consider  a
security  covered by a call option to be  "pledged"  as that term is used in the
Fund's policy which limits the pledging or mortgaging of their assets.

         The Fund will purchase a call option only when entering into a "closing
purchase  transaction,"  i.e., a purchase of a call option on the same  security
with the same exercise  price and  expiration  date as a "covered"  call already
written by the Fund.  There is no assurance that the Fund will be able to effect
such closing  purchase  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. The Fund's  portfolio  turnover may increase  through
the  exercise  of  options  if the  market  price of the  underlying  securities
appreciates  and the Fund has not entered into a closing  purchase  transaction.
The commission on purchase or sale of a call option is higher in relation to the


                                      B-2
<PAGE>

premium than the  commission in relation to the price on purchase or sale of the
underlying security.

         Foreign Securities

         The Fund may  invest a portion  of its  assets in  foreign  securities.
Investment  in securities of foreign  companies and countries  involves  certain
considerations  and risks that are not typically  associated  with investment in
U.S.  Government  securities  and  securities  of  domestic  companies.  Foreign
companies  are  not  generally  subject  to  uniform  accounting,  auditing  and
financial  standards and  requirements  comparable  to those  applicable to U.S.
companies.  There may also be less  government  supervision  and  regulation  of
foreign  securities  exchanges,  brokers and listed companies than exists in the
United States.  Dividends and interest paid by foreign issuers may be subject to
withholding  and other  foreign  taxes which may decrease the net return on such
investments  as compared to interest paid to the Fund by the U.S.  Government or
by  domestic   companies.   In  addition,   there  may  be  the  possibility  of
expropriations, confiscatory taxation, political, economic or social instability
or diplomatic developments which could affect assets of the Fund held in foreign
countries.  The  value  of  foreign  securities  may be  adversely  affected  by
fluctuations  in the  relative  rates of  exchange  between  the  currencies  of
different  nations  and by  exchange  control  regulations.  There  may be  less
publicly available  information about foreign companies and governments compared
to reports and ratings published about U.S.  companies.  Some foreign securities
markets have  substantially  less volume than domestic markets and securities of
some foreign  companies  are less liquid and more  volatile  than  securities of
comparable  U.S.  companies.  In  connection  with its  investments  in  foreign
securities and in order to protect against uncertainty in future exchange rates,
the Fund may engage in foreign currency exchange transactions.

         Debt Securities

         No more  than 5% of the  Fund's  net  assets  may be  invested  in debt
securities,  including convertible  securities,  rated below "BBB" by Standard &
Poor's Ratings Group ("Standard & Poor's") or the equivalent. If the rating of a
debt security is reduced below  investment  grade ("BBB" or higher),  management
will  consider  whatever  action  is  appropriate,  consistent  with the  Fund's
investment objective and policies.

         Bonds rated below "BBB" or comparable  unrated  securities are commonly
referred  to  as  "junk  bonds"  and  are  considered  speculative  and  may  be
questionable as to principal and interest  payments.  In some cases,  such bonds
may be highly speculative,  have poor prospects for reaching investment standing
and be in default.  As a result,  investment  in such bonds will entail  greater
speculative  risks than those  associated  with  investment in investment  grade
bonds (i.e.,  bonds rated "BBB" or better by Standard & Poor's or, if unrated by
such rating  organization,  determined to be of comparable quality by the Fund's
investment adviser).

         The amount of junk bond  securities  outstanding  has  proliferated  in
conjunction  with the increase in merger and  acquisition  and leveraged  buyout
activity.  An  economic  downturn  could  severely  affect the ability of highly
leveraged   issuers  to  service  their  debt  obligations  or  to  repay  their
obligations upon maturity.  Factors having an adverse impact on the market value
of lower quality  securities will have an adverse effect on the Fund's net asset
value to the extent that it invests in such  securities.  In addition,  the Fund
may incur additional expenses to the extent it is required to seek recovery upon
a default in payment of principal or interest on its portfolio holdings.

                                      B-3
<PAGE>

         The secondary market for junk bond securities, which is concentrated in
relatively few market makers,  may not be as liquid as the secondary  market for
more highly rated  securities,  a factor which may have an adverse effect on the
Fund's  ability to dispose of a particular  security when  necessary to meet its
liquidity  needs.  Under adverse  market or economic  conditions,  the secondary
market for junk bond  securities  could  contract  further,  independent  of any
specific adverse changes in the condition of a particular  issuer.  As a result,
the Fund could find it more difficult to sell these securities or may be able to
sell the  securities  only at prices lower than if such  securities  were widely
traded. Prices realized upon the sale of such lower rated or unrated securities,
under these  circumstances,  may be less than the prices used in calculating the
Fund's net asset value.

         Certain  proposed  and recently  enacted  federal  laws  including  the
required divestiture by federally insured savings and loan associations of their
investments  in junk bonds and  proposals  designed to limit the use, or tax and
other advantages,  of junk bond securities could adversely affect the Fund's net
asset value and investment practices. Such proposals could also adversely affect
the  secondary  market for junk bond  securities,  the  financial  condition  of
issuers of these  securities and the value of outstanding  junk bond securities.
The form of such proposed  legislation and the  possibility of such  legislation
being passed are uncertain.

         Since  investors  generally  perceive  that  there  are  greater  risks
associated with the medium to lower quality debt securities of the type in which
the Fund may  invest a portion  of its  assets,  the  yields  and prices of such
securities may tend to fluctuate more than those for higher rated securities. In
the lower quality segments of the debt securities market, changes in perceptions
of  issuers'  creditworthiness  tend  to  occur  more  frequently  and in a more
pronounced  manner  than do  changes  in  higher  quality  segments  of the debt
securities market, resulting in greater yield and price volatility.

         Medium to lower rated and comparable  unrated debt  securities  tend to
offer  higher  yields  than higher  rated  securities  with the same  maturities
because the historical financial condition of the issuers of such securities may
not have been as strong as that of other  issuers.  Since  medium to lower rated
securities  generally involve greater risks of loss of income and principal than
higher rated securities,  investors should consider carefully the relative risks
associated with investment in securities which carry medium to lower ratings and
in comparable unrated securities.  In addition to the risk of default, there are
the related costs of recovery on defaulted issues. The Fund's investment adviser
will  attempt to reduce these risks  through  portfolio  diversification  and by
analysis of each  issuer and its  ability to make timely  payments of income and
principal, as well as broad economic trends and corporate developments.

         The prices of all debt  securities  generally  fluctuate in response to
the general level of interest rates. Another factor which causes fluctuations in
the prices of debt  securities  is the supply  and  demand for  similarly  rated
securities.  Fluctuations  in the prices of portfolio  securities  subsequent to
their  acquisition will not affect any cash income from such securities but will
be reflected in the Fund's net asset value.

         Investment Restrictions

         The  restrictions  set  forth  in the  next  sentence  are  fundamental
policies of the Fund which may not be changed  without the  affirmative  vote of
the  holders of a  majority  of the Fund's  outstanding  shares.  As used in the
Prospectus and this Statement of Additional Information, such approval means the
approval  of the  lesser  of (i)  the  holders  of 67%  or  more  of the  shares
represented  at a meeting  if the  holders  of more than 50% of the  outstanding
shares are  present in person or by proxy,  or (ii) the holders of more than 50%
of the outstanding shares.

                                      B-4

         The Fund may not:

         (1)  purchase  securities  "on  margin"  or  effect  "short  sales"  of
securities;

         (2)  underwrite any issue of securities;

         (3) acquire the securities of any other domestic or foreign  investment
company  or  investment  fund  (except  in  connection  with a plan of merger or
consolidation  with or acquisition of substantially all the assets of such other
investment  company);  provided,  however,  that nothing herein  contained shall
prevent  the Fund from  investing  in the  securities  issued  by a real  estate
investment  trust,  provided that such trust shall not be permitted to invest in
real estate or interests in real estate other than  mortgages or other  security
interests;

         (4) purchase  securities  of a company if the purchase  would result in
the Fund  having  more  than 5% of the  value of its total  assets  invested  in
securities of such company;

         (5) purchase  securities  of a company if the purchase  would result in
the Fund  owning  more than 10% of the  outstanding  voting  securities  of such
company;

         (6) purchase  securities for the purpose of  controlling  management of
other companies;

         (7) invest in commodities, commodity contracts, or real estate;

         (8) purchase "investment letter" securities (i.e., securities that must
be  registered  under the  Securities  Act of 1933 before they may be offered or
sold to the public);

         (9)  purchase the  securities  of any  enterprise  which has a business
history of less than three years,  including  the  operation of any  predecessor
business to which it has succeeded;

         (10) purchase or retain the  securities of any issuer if those officers
and  Trustees  of the Fund,  their  adviser  or  principal  underwriter,  owning
individually more than one-half of 1% of the securities of such issuer, together
own more than 5% of the securities of such issuer;

         (11) make loans, provided that (i) the purchase of publicly distributed
debt securities pursuant to the Fund's investment objectives shall not be deemed
loans for the purposes of this restriction,  (ii) loans of portfolio  securities
as described,  from time to time, under "Lending of Portfolio  Securities" shall
be made only in accordance  with the terms and conditions  therein set forth and
(iii) in seeking a return on temporarily  available cash, the Fund may engage in
repurchase  transactions  with banks  maturing in one week or less and involving
obligations of the U.S. Government, its agencies or instrumentalities;

         (12)  borrow   money,   except  that,   as  a  temporary   measure  for
extraordinary or emergency  purposes and not for investment  purposes,  the Fund
may borrow  from banks up to 10% of the value of their net assets at the time of
the borrowing; or

         (13)  guarantee  the  securities  of any other  company,  or  mortgage,
pledge,  hypothecate,  assign or otherwise encumber as security for indebtedness
its securities or receivables in an amount exceeding the amount of the borrowing
secured  thereby.  If the Fund  borrows  money as a temporary  measure,  it must
comply with  restrictions  on  borrowing in the  Investment  Company Act of 1940


                                      B-5
<PAGE>

whereby it has undertaken not to make  additional  portfolio  investments  while
such borrowing exceeds 5% of its net assets.

         It is the  policy of the Fund not to  concentrate  its  investments  in
securities of companies in any particular  industry or group of  industries.  In
the opinion of the staff of the  Securities  and  Exchange  Commission  ("SEC"),
investments  are  concentrated  in a  particular  industry  if such  investments
aggregate 25% or more of the Fund's total  assets.  The Fund has agreed to abide
by the  foregoing  non-fundamental  policy which it will not change  without the
affirmative vote of the holders of a majority of the Fund's  outstanding  shares
of beneficial interest.

         In addition,  in connection  with the offering of its shares in various
states and foreign countries, the Fund has agreed to abide by certain additional
restrictions  which may not be changed  without the  approval of the  regulatory
agencies in such states and foreign  countries (but which may be changed without
notice to or approval of the Fund's  shareholders).  These restrictions are that
the Fund will not: (1) purchase the  securities  of any issuer if such  purchase
would result in the Fund owning more than 10% of any class of securities of such
issuer;  (2) invest in uncovered puts or calls,  or straddles,  spreads,  or any
combination  thereof,  or in oil, gas or other mineral  leases or exploration or
development programs; (3) borrow in excess of 10% of gross assets taken at cost;
(4) pledge, mortgage,  hypothecate or otherwise encumber any assets of the Fund;
(5) invest in foreign  securities  (exclusive  of foreign  securities  listed on
recognized  domestic  or  foreign  securities  exchanges),  together  with other
investments  which are not  readily  marketable,  in excess of 5% of average net
assets;  and (6) invest more than 5% of its total assets in warrants,  valued at
the lower of cost or market, or more than 2% of its total assets in warrants, so
valued, which are not listed on either the New York or American Stock Exchanges.

*    ITI  Pioneer  AMC Ltd.  manages the Fund's  investments  in India,  and PMC
     manages all of the Fund's other investments.
**   This fund is a closed-end fund underwritten by Mellon Bank.
***  This  Trust  consists  of seven  separate  portfolios  designed  to provide
     investment  vehicles for the variable  annuity and variable life  insurance
     contracts of various  insurance  companies or for certain qualified pension
     plans.
    

         PMC, the Trust's  investment  adviser,  also manages the investments of
certain  institutional  private accounts.  Messrs.  Cogan,  Tripple,  Keough and
Barri,  officers and/or Trustees of the Fund, are also officers and/or directors
of PFD, PMC, PSC (except Mr.  Tripple) and PGI. To the knowledge of the Fund, no
officer or  Trustee  of the Fund owned 5% or more of the issued and  outstanding
shares of PGI as of the date of this Statement of Additional Information, except
Mr. Cogan who then owned  approximately  15% of such  shares.  As of the date of
this Statement of Additional Information,  the Trustees and officers of the Fund
owned less than 1% of the outstanding securities of the Fund.

         Compensation of Officers and Trustees

         The Fund pays no salaries or compensation  to any of its officers.  The
Fund pays an annual  trustees' fee of $5,000 and a payment of $300 plus expenses
per meeting attended, to each Trustee who is not affiliated with PMC, PFD or PSC
and  pays  an  annual  trustees'  fee of $500  plus  expenses  to  each  Trustee
affiliated  with PMC, PFD or PSC. Any such fees and expenses  paid to affiliates
or  interested  persons of PMC, PFD or PSC are  reimbursed to the Fund under its
management contract.

         3.   INVESTMENT ADVISER

         The  Fund  has   contracted   with  PMC,  60  State   Street,   Boston,
Massachusetts,  to act as its investment adviser.  PMC assists in the management
of the Fund and is authorized in its  discretion to buy and sell  securities for
the  account  of the  Fund,  subject  to the  right of the  Fund's  trustees  to
disapprove  any such purchase or sale. The term of the contract is one year, but
it is  renewable  annually by vote of a majority of the Board of Trustees of the
Fund  (including  a majority of the Trustees who are not parties to the contract
or interested  persons of any such  parties) cast in person at a meeting  called
for the purpose of voting on such renewal.  The contract  terminates if assigned
and may be  terminated  without  penalty by either party by vote of its Board of
Directors or Trustees or vote of a majority of its  outstanding  securities  and
the giving of sixty days' written notice.  The management  contract was approved
by the shareholders of the Fund at a meeting of shareholders held on October 12,
1990. As compensation  for its management  services and expenses  incurred,  PMC
receives  0.50%  per  annum  of  the  Fund's  average  daily  net  assets  up to
$250,000,000,  0.48% of such assets between  $250,000,000 and $300,000,000,  and
0.45% of such assets in excess of  $300,000,000.  The fee is computed  daily and
paid monthly.

         During its fiscal years ended  December 31,  1994,  1993 and 1992,  the
Fund paid or owed management fees to PMC of approximately $9,362,000, $8,774,000
and $7,734,000, respectively.

         4.   SHAREHOLDER SERVICING/TRANSFER AGENT

         The Fund has contracted with Pioneering Services  Corporation  ("PSC"),
60 State Street, Boston, Massachusetts,  to act as its dividend disbursing agent
and transfer agent.  This contract  terminates if assigned and may be terminated
without penalty by either party by vote of its Board of Directors or Trustees or
a majority of its  outstanding  voting  securities and the giving of sixty days'
written notice.

         Under the terms of its contract with the Fund, PSC services shareholder
accounts,  and  its  duties  include:  (i)  processing  sales,  redemptions  and
exchanges  of  Fund  shares;  (ii)  distributing  dividends  and  capital  gains
associated  with  Fund  accounts;  and (iii)  maintaining  account  records  and
responding to shareholder inquiries.

         PSC receives an annual fee of $22.00 per  shareholder  account from the
Fund as compensation  for the services  described  above.  This fee is set at an
amount  determined  by vote of a majority of the Fund's  Trustees  (including  a
majority  of the  Trustees  who are not  parties  to the  contract  with  PSC or
interested  persons  of any  such  parties)  to be  comparable  to fees for such
services being paid by other investment companies.

         5.   CUSTODIAN

         Brown Brothers Harriman & Co. (the "Custodian") is the custodian of the
Fund's  assets.  The  Custodian's   responsibilities   include  safekeeping  and
controlling the Fund's cash and securities, handling the receipt and delivery of
securities, and collecting interest and dividends on the Fund's investments. The


                                      B-10
<PAGE>

Custodian does not determine the investment policies of the Fund or decide which
securities  the  Fund  will  buy or  sell.  The Fund  may,  however,  invest  in
securities,  including  repurchase  agreements,  issued by the Custodian and may
deal with the  Custodian  as  principal in  securities  transactions.  Portfolio
securities may be deposited into the Federal  Reserve-Treasury  Department  Book
Entry System or the Depository Trust Company.

         6.   PRINCIPAL UNDERWRITER

         PFD, 60 State Street,  Boston,  Massachusetts,  serves as the principal
underwriter  for the Fund in  connection  with the  continuous  offering  of its
shares.  The Fund has  entered  into an  Underwriting  Agreement  with PFD.  The
Underwriting  Agreement will continue from year to year if annually  approved by
the Trustees in conjunction with the continuance of the Plan (as defined below).
The Underwriting Agreement provides that PFD will bear the distribution expenses
of the Fund not borne by the Fund.  During the Fund's 1994, 1993 and 1992 fiscal
years, net underwriting commissions retained by PFD were approximately $990,413,
$880,000 and $831,000,  respectively.  Commissions  reallowed to dealers for the
1994, 1993 and 1992 fiscal years were approximately  $6,589,413,  $7,303,666 and
$5,595,989, respectively.

         PFD  bears all  expenses  it incurs  in  providing  services  under the
Underwriting Agreement.  Such expenses include compensation to its employees and
representatives  and to securities  dealers for  distribution  related  services
performed for the Fund.  PFD also pays certain  expenses in connection  with the
distribution of the Fund's shares, including the cost of preparing, printing and
distributing  advertising or promotional materials, and the cost of printing and
distributing prospectuses and supplements to prospective shareholders.  The Fund
bears the cost of  registering  its  shares  under  federal,  state and  foreign
securities  law.  The Fund and PFD have agreed to indemnify  each other  against
certain liabilities,  including liabilities under the Securities Act of 1933, as
amended.  Under the  Underwriting  Agreement,  PFD will use its best  efforts in
rendering services to the Fund.

         The Fund will not generally issue Fund shares for  consideration  other
than cash. At the Fund's sole discretion,  however, it may issue Fund shares for
consideration  other than cash in connection  with an  acquisition  of portfolio
securities  (other than  municipal  debt  securities  issued by state  political
subdivisions  or their  agencies or  instrumentalities)  pursuant to a bona fide
purchase of assets,  merger or other reorganization  provided (i) the securities
meet the investment objectives and policies of the Fund; (ii) the securities are
acquired by the Fund for investment and not for resale; (iii) the securities are
not restricted as to transfer either by law or liquidity of market; and (iv) the
securities have a value which is readily ascertainable (and not established only
by  evaluation  procedures)  as  evidenced  by a listing on the  American  Stock
Exchange  or the New  York  Stock  Exchange,  or by  quotation  under  the  NASD
Automated  Quotation  System.  An  exchange of  securities  for Fund shares will
generally be a taxable transaction to the shareholder.

         7.   DISTRIBUTION PLAN

         The Fund has  adopted a plan of  distribution  pursuant  to Rule  12b-1
under the 1940 Act (the "Plan") pursuant to which the Fund may reimburse PFD for
its expenditures in financing any activity  primarily  intended to result in the
sale of the shares of the Fund.  Certain  categories of such  expenditures  have
been approved by the Board of Trustees and are set forth in the Prospectus.  See
"Distribution Plan" in the Prospectus.  The expenses of the Fund pursuant to the
Plan are  accrued on a fiscal  year basis and may not exceed the annual  rate of
0.25% of the Fund's average annual net assets.  In accordance  with the terms of
the Plan,  PFD  provides  to the Fund for  review by the  Trustees  a  quarterly


                                      B-11
<PAGE>

written report of the amounts  expended under the Plan and the purpose for which
such expenditures were made. In the Trustees' quarterly review of the Plan, they
will consider its continued  appropriateness  and the level of  compensation  it
provides.

         No  interested  person of the Fund,  nor any Trustee of the Fund who is
not an  interested  person of the Fund,  has any  direct or  indirect  financial
interest in the  operation of the Plan except to the extent that PFD and certain
of its employees may be deemed to have such an interest as a result of receiving
a portion of the amounts  expended  under the Plan by the Fund and except to the
extent certain officers may have an interest in PFD's ultimate parent, PGI.

         The Plan was  adopted  by a  majority  vote of the  Board of  Trustees,
including  all of the Trustees who are not, and were not at the time they voted,
interested  persons of the Fund, as defined in the 1940 Act (none of whom had or
had any direct or indirect  financial  interest in the  operation  of the Plan),
cast in person at a meeting  called for the  purpose  of voting on the Plan.  In
approving the Plan, the Trustees identified and considered a number of potential
benefits which the Plan may provide.  The Board of Trustees  believes that there
is a reasonable  likelihood  that the Plan will benefit the Fund and its current
and future  shareholders.  Under its terms, the Plan remains in effect from year
to year provided such  continuance is approved  annually by vote of the Trustees
in the  manner  described  above.  The  Plan  may  not be  amended  to  increase
materially the annual  percentage  limitation of average net assets which may be
spent for the services described therein without approval of the shareholders of
the Fund,  and  material  amendments  of the Plan must also be  approved  by the
Trustees in the manner  described above. The Plan may be terminated at any time,
without payment of any penalty,  by vote of the majority of the Trustees who are
not  interested  persons  of the Fund and have no direct or  indirect  financial
interest  in the  operations  of the  Plan,  or by a vote of a  majority  of the
outstanding voting securities of the Fund (as defined in the 1940 Act). The Plan
was approved at a meeting of  shareholders  held on October 15,  1991.  The Plan
will  automatically  terminate in the event of its assignment (as defined in the
1940 Act).

         During the fiscal year ended December 31, 1994, the Fund incurred total
distribution  fees pursuant to the Plan of  $3,361,000.  Distribution  fees were
paid by the  Fund to PFD in  reimbursement  of  expenses  related  to  services,
shareholder accounts and to compensating dealers and sales personnel.

         8.   INDEPENDENT PUBLIC ACCOUNTANTS

         Arthur  Andersen  LLP are the Fund's  independent  public  accountants,
providing audit  services,  tax return review,  and assistance and  consultation
with  respect to the  preparation  of filings with the  Securities  and Exchange
Commission.

         9.   PORTFOLIO TRANSACTIONS

         All orders for the purchase or sale of portfolio  securities are placed
on behalf of the Fund by PMC pursuant to authority  contained in the  management
contract (subject to the right of the Trustees to reverse any such transaction).
The  primary   consideration  in  placing  portfolio  security  transactions  is
execution at the most favorable  prices.  Additionally,  in selecting brokers or
dealers, PMC will consider various relevant factors,  including, but not limited
to,  the size and type of the  transaction;  the  nature  and  character  of the
markets for the  security to be  purchased or sold;  the  execution  efficiency,
settlement  capability,  and  financial  condition  of the dealer;  the dealer's
execution services rendered on a continuing basis; and the reasonableness of any
dealer spreads.

                                      B-12
<PAGE>

         In circumstances  where two or more broker-dealers are in a position to
offer  comparable  prices and  execution,  dealers may be  selected  who provide
brokerage and/or research services to the Fund and/or other investment companies
managed by PMC, or who sell shares of the Fund. In addition,  if PMC  determines
in good faith that the amount of  commissions  charged by a broker is reasonable
in relation to the value of the brokerage and research services provided by such
broker,  the Fund may pay  commissions  to such broker in an amount greater than
the amount another firm may charge.  Brokerage and research services may include
advice  concerning the value of securities;  the  advisability  of investing in,
purchasing  or  selling  securities;  the  availability  of  securities  or  the
purchasers or sellers of securities;  providing stock price quotation  services;
furnishing  analyses,  electronic  information  services,  manuals  and  reports
concerning  issuers,  industries,   securities,  economic  factors  and  trends,
portfolio  strategy,  performance of accounts,  comparative  fund statistics and
credit rating service  information;  and effecting  securities  transactions and
performing functions incidental thereto (such as clearance and settlement).  PMC
maintains  a listing of dealers who provide  such  services on a regular  basis.
However,  because it is anticipated that many transactions on behalf of the Fund
and other investment companies managed by PMC are placed with dealers (including
dealers on the listing) without regard to the furnishing of such services, it is
not possible to estimate the  proportion of such  transactions  directed to such
dealers solely because such services were provided.  Management believes that no
exact dollar value can be calculated for such services.

         The receipt of research  from dealers may be useful to PMC in rendering
investment  management  services  to the Fund  and  other  investment  companies
managed by PMC, and conversely,  such information provided by brokers or dealers
who have executed  transaction orders on behalf of such other PMC clients may be
useful to PMC in carrying out its  obligations  to the Fund. The receipt of such
research has not reduced PMC's normal independent research activities;  however,
it  enables  PMC to avoid the  additional  expenses  which  might  otherwise  be
incurred if it were to attempt to develop comparable information through its own
staff.

         The   Trustees   periodically   review   PMC's   performance   of   its
responsibilities  in connection with the placement of portfolio  transactions on
behalf of the Fund.  During the fiscal years ended  December 31, 1994,  1993 and
1992,  the  Fund  paid or owed  total  brokerage  commissions  of  approximately
$1,016,736, $1,270,000 and $1,245,000, respectively.

         The Fund is managed by Pioneering Management Corporation ("PMC"), which
also serves as investment adviser to other mutual funds in the Pioneer group and
private  accounts  with  investment  objectives  similar  to those of the  Fund.
Securities  frequently  meet the investment  objectives of the Fund,  such other
mutual  funds in the  Pioneer  group and such other  private  accounts.  In such
cases, the decision to recommend a purchase to one mutual fund or account rather
than the other is based on a number of factors.  The determining factors in most
cases are the amount of securities of the issuer then outstanding,  the value of
those  securities  and the  market for them.  Other  factors  considered  in the
investment recommendations include other investments which each client presently
has in a particular  industry and the  availability of investment  funds in each
client account.

         It is possible that at times identical  securities will be held by more
than one fund  and/or  account.  However,  the  position  of any mutual  fund or
account in the same  issue may vary and the length of time that any mutual  fund
or account  may  choose to hold its  investment  in the same issue may  likewise
vary. To the extent that the Fund, another mutual fund in the Pioneer group or a
private  account  managed by PMC seeks to acquire the same security at about the
same  time,  the Fund may not be able to  acquire  as large a  position  in such
security  as it desires or it may have to pay a higher  price for the  security.
Similarly,  the Fund may not be able to obtain as large an execution of an order
to sell or as high a price for any particular  portfolio security if PMC decides


                                      B-13
<PAGE>

to sell on behalf of another  account  the same  portfolio  security at the same
time. On the other hand, if the same  securities  are bought or sold at the same
time  by  more  than  one  account,   the  resulting   participation  in  volume
transactions could produce better executions for the Fund or the account. In the
event that more than one account purchases or sells the same security on a given
date,  the purchases and sales will normally be made as nearly as practicable on
a pro rata basis in proportion to the amounts desired to be purchased or sold by
each. Although some of the other mutual funds in the Pioneer group have the same
general  investment  objectives  and  fundamental  policies  as the Fund,  their
portfolios do not generally  consist of the same investments as the Fund or each
other and their performance results are likely to differ from that of the Fund.

         10.  DIVIDENDS AND TAX STATUS

         It is the Fund's policy to meet the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended (the "Code"),  for  qualification as a
regulated  investment  company.  The  requirements  relate to the sources of its
income,  diversification  of its  assets  and  distributions  of its  income  to
shareholders.  If the Fund meets all such  requirements  and  distributes to its
shareholders, in accordance with the Code's timing requirements,  all investment
company taxable income and net capital gain, if any, which it receives, the Fund
will be relieved of the necessity of paying federal income tax.

         Dividends from investment  company  taxable income,  which includes net
investment  income,  net  short-term  capital  gain in excess  of net  long-term
capital  loss,  and certain net foreign  exchange  gains are taxable as ordinary
income,  whether  received in cash or in additional  shares.  Dividends from net
long-term capital gain in excess of net short-term capital loss, if any, whether
received in cash or additional shares, are taxable to the Fund's shareholders as
long-term  capital gains for federal  income tax purposes  without regard to the
length of time shares of the Fund have been held.  The federal income tax status
of all distributions will be reported to shareholders annually.

         Any dividend  declared by the Fund in October,  November or December as
of a record date in such a month and paid during the  following  January will be
treated for federal income tax purposes as received by  shareholders on December
31 of the calendar year in which it is declared.

         Foreign  exchange  gains and losses  realized by the Fund in connection
with  certain   transactions   involving   foreign   currency-denominated   debt
securities,  forward foreign currency contracts, foreign currencies, or payables
or receivables  denominated in a foreign  currency are subject to Section 988 of
the Code, which generally causes such gains and losses to be treated as ordinary
income  and  losses  and  may  affect  the  amount,   timing  and  character  of
distributions to shareholders.

         If the  Fund  acquires  stock in  certain  non-U.S.  corporations  that
receive at least 75% of their annual gross income from passive  sources (such as
interest,  dividends,  rents, royalties or capital gain) or hold at least 50% of
their assets in  investments  producing such passive  income  ("passive  foreign
investment  companies"),  the Fund could be  subject  to federal  income tax and
additional  interest  charges  on  "excess  distributions"  received  from  such
companies or gain from the sale of stock in such  companies,  even if all income
or gain actually received by the Fund is timely distributed to its shareholders.
The Fund  would not be able to pass  through to its  shareholders  any credit or
deduction for such a tax. Certain elections may, if available,  ameliorate these
adverse  tax  consequences,  but any such  election  would  require  the Fund to
recognize  taxable  income or gain without the  concurrent  receipt of cash. The
Fund may  limit  and/or  manage  its  holdings  in  passive  foreign  investment
companies  to  minimize  its tax  liability  or  maximize  its return from these
investments.

         The Fund may invest in debt  obligations  that are in the lower  rating
categories or are unrated.  Investments in debt  obligations that are at risk of
default  present  special  tax issues for the Fund.  Tax rules are not  entirely
clear about issues such as when the Fund may cease to accrue interest,  original
issue discount,  or market discount,  when and to what extent  deductions may be
taken  for  bad  debts  or  worthless  securities,   how  payments  received  on
obligations in default  should be allocated  between  principal and income,  and
whether  exchanges of debt  obligations in a workout context are taxable.  These
and other issues will be addressed by the Fund,  in the event it invests in such
securities, in order to ensure that it distributes sufficient income to preserve
its status as a regulated  investment  company and to avoid becoming  subject to
federal income or excise tax.

         If the Fund invests in certain  PIKs,  zero coupon  securities,  or, in
general,  any other  securities  with  original  issue  discount (or with market
discount if the Fund elects to include market discount in income currently), the
Fund  must  accrue  income  on such  investments  prior  to the  receipt  of the
corresponding  cash  payments.  However,  the  Fund  must  distribute,  at least
annually,  all or  substantially  all of its net income,  including such accrued
income, to shareholders to qualify as a regulated  investment  company under the
Code and avoid Federal income and excise taxes. Therefore,  the Fund may have to
dispose of its  portfolio  securities  under  disadvantageous  circumstances  to
generate cash, or may have to leverage  itself by borrowing the cash, to satisfy
distribution requirements.

         At the time of an investor's  purchase of Fund shares, a portion of the
purchase price is often  attributable to realized or unrealized  appreciation in
the Fund's portfolio or undistributed taxable income of the Fund.  Consequently,
subsequent distributions from such appreciation or income may be taxable to such
investor even if the net asset value of the investor's shares is, as a result of
the  distributions,  reduced below the  investor's  cost for such shares and the
distributions in reality represent a return of a portion of the investment.

         Any loss realized by a shareholder upon the redemption of shares with a
tax holding period of six months or less will be treated as a long-term  capital
loss to the extent of any amounts treated as distributions of long-term  capital
gain with respect to such shares.

         In addition,  if shares  redeemed or exchanged  have been held for less
than 91 days, (1) in the case of a  reinvestment  at net asset value pursuant to
the reinvestment privilege, the sales charge paid on such shares is not included
in their tax basis under the Code, and (2) in the case of an exchange,  all or a
portion of the sales  charge  paid on such  shares is not  included in their tax
basis under the Code, to the extent a sales charge that would otherwise apply to
the shares  received is reduced  pursuant to the exchange  privilege.  In either
case,  the  portion  of the sales  charge not  included  in the tax basis of the
shares  redeemed or  surrendered  in an exchange is included in the tax basis of
the  shares  acquired  in  the  reinvestment  or  exchange.  Losses  on  certain
redemptions  may be  disallowed  under  "wash  sale" rules in the event of other
investments  in the Fund within a period of 61 days beginning 30 days before and
ending 30 days after a redemption or other sale of shares.

         Options written by the Fund on certain securities may cause the Fund to
recognize gains or losses from  marking-to-market at the end of its taxable year
even though such options may not have lapsed,  been closed out, or exercised and
may affect the characterization as long-term or short-term of some capital gains
and losses  realized by the Fund.  Losses on certain  options and/or  offsetting
positions  (portfolio  securities or other  positions  with respect to which the
Fund's risk of loss is substantially diminished by one or more options) may also
be deferred under the tax straddle rules of the Code,  which may also affect the
characterization  of capital gains or losses from straddle positions and certain
successor  positions as long-term or short- term.  The effect of these rules may


                                      B-15
<PAGE>

be  mitigated  to the extent the Fund limits its  option-writing  to  "qualified
covered call options" on portfolio  stock.  The tax rules  applicable to options
and straddles  may affect the amount,  timing and character of the Fund's income
and losses and hence of its distributions to shareholders.

         For  purposes  of the 70%  dividends-received  deduction  available  to
corporations,  dividends  received  by the  Fund,  if any,  from  U.S.  domestic
corporations  in respect of any share of stock with a tax  holding  period of at
least 46 days (91 days in the case of certain preferred stock) in an unleveraged
position and distributed and designated by the Fund may be treated as qualifying
dividends.  Any corporate  shareholder  should consult its tax advisor regarding
the  possibility  that its tax basis in its shares may be  reduced,  for Federal
income  tax  purposes,  by reason of  "extraordinary  dividends"  received  with
respect to the shares.  Corporate  shareholders  must meet the  minimum  holding
period requirement stated above (46 or 91 days), taking into account any holding
period  reductions from certain hedging or other positions that diminish risk of
loss,  with  respect to their Fund shares in order to qualify for the  deduction
and,  if they  borrow to  acquire  Fund  shares,  may be denied a portion of the
dividends-received  deduction.  The entire  qualifying  dividend,  including the
otherwise deductible amount, will be included in determining the excess (if any)
of a  corporation's  adjusted  current  earnings  over its  alternative  minimum
taxable  income,  which may  increase a  corporation's  alternative  minimum tax
liability.

         The Fund may be  subject  to  withholding  and other  taxes  imposed by
foreign  countries  with  respect to its  investments  in those  countries.  Tax
conventions  between certain countries and the U.S. may reduce or eliminate such
taxes.  The Fund does not expect to satisfy the requirements for passing through
to  shareholders  their pro rata shares of foreign taxes paid by the Fund,  with
the result that  shareholders will not include such taxes in their gross incomes
and will not be  entitled to a tax  deduction  or credit for such taxes on their
own tax returns.

         Different  tax  treatment,   including   penalties  on  certain  excess
contributions  and  deferrals,   certain   pre-retirement  and   post-retirement
distributions,  and  certain  prohibited  transactions,  is accorded to accounts
maintained as qualified retirement plans.
Shareholders should consult their tax advisers for more information.

   
         Federal law requires that the Fund withhold 31% of reportable  payments
including  dividends,  capital gain  dividends  and the proceeds of  redemptions
(including exchanges) and repurchases to shareholders who have not complied with
Internal Revenue Service ("IRS") regulations. In order to avoid this withholding
requirement, shareholders must certify on their Applications, or on separate W-9
Forms,  that the Social  Security or other Taxpayer  Identification  Number they
provide  is their  correct  number  and that they are not  currently  subject to
backup withholding,  or that they are exempt from backup  withholding.  The Fund
may nevertheless be required to withhold if it receives notice from the IRS or a
broker that the number provided is incorrect or backup withholding is applicable
as a result of previous underreporting of interest or dividend income.
    

         Provided  that the Fund  qualifies  as a regulated  investment  company
under  the  Code,  it will  not be  required  to pay any  Massachusetts  income,
corporate excise or franchise taxes.

         The  description   above  relates  only  to  U.S.  federal  income  tax
consequences  for  shareholders  who are U.S.  persons,  i.e.  U.S.  citizens or
residents,  or U.S. corporations,  partnerships,  trusts or estates, and who are
subject to U.S.  federal  income  tax.  This  description  does not  address the
special tax rules  applicable to particular  types of investors,  such as banks,
insurance  companies or tax exempt  entities.  Investors other than U.S. persons
may be subject to different  U.S. tax  treatment,  including a possible 30% U.S.
withholding  tax (or  withholding tax at a lower treaty rate) on amounts treated


                                      B-16
<PAGE>

as ordinary  dividends  from the Fund and,  unless an effective  IRS Form W-8 or
authorized  substitute  is on file, to 31% backup  withholding  on certain other
payments from the Fund.  Shareholders  should  consult their own tax advisers on
these matters and on state, local and other applicable tax laws.

         11.  DESCRIPTION OF SHARES

         The  Fund's  Declaration  of Trust  permits  its Board of  Trustees  to
authorize the issuance of an unlimited  number of full and fractional  shares of
beneficial  interest (without par value) which may be divided into such separate
series as the Trustees may  establish.  The  Trustees may  establish  additional
series of shares,  and may divide or combine the shares into a greater or lesser
number  of  shares  without  thereby  changing  the   proportionate   beneficial
interests. Each share represents an equal proportionate interest with each other
share.  The shares of any  additional  series would  participate  equally in the
earnings,  dividends and assets of the particular  series, and would be entitled
to vote  separately  to approve  investment  advisory  agreements  or changes in
investment  restrictions,  but shareholders of all series would vote together in
the election and selection of Trustees and accountants.  Upon liquidation of the
Fund, the Fund's  shareholders  are entitled to share pro rata in the Fund's net
assets available for distribution to shareholders.

         Shareholders  are entitled to one vote for each share held and may vote
in the  election  of  Trustees  and on other  matters  submitted  to meetings of
shareholders.  Although  Trustees are not elected annually by the  shareholders,
shareholders  have under certain  circumstances  the right to remove one or more
Trustees.  No material  amendment may be made to the Fund's Declaration of Trust
without  the  affirmative  vote  of the  holders  of a  majority  of the  Fund's
outstanding  shares as defined in the 1940 Act.  Shares  have no  preemptive  or
conversion rights.  Shares are fully paid and non-assessable by the Fund, except
as set forth below. See "Certain Liabilities."

         12.  CERTAIN LIABILITIES

         As a Massachusetts  business trust, the Fund's  operations are governed
by its  Declaration  of Trust dated April 16,  1985,  a copy of which is on file
with the office of the Secretary of State of The Commonwealth of  Massachusetts.
Theoretically, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held  personally  liable  for the  obligations  of the trust.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability for acts or  obligations  of the Fund and requires that notice of such
disclaimer be given in each agreement,  obligation or instrument entered into or
executed  by the  Fund or the  Trustees.  Moreover,  the  Declaration  of  Trust
provides for the  indemnification out of the Fund's property of any shareholders
held personally liable for any obligations of the Fund. The Declaration of Trust
also provides that the Fund shall, upon request, assume the defense of any claim
made against any  shareholder  for any act or obligation of the Fund and satisfy
any judgment thereon.  Thus, the risk of a shareholder  incurring financial loss
beyond his or her investment  because of shareholder  liability would be limited
to  circumstances  in  which  the  Fund  itself  would  be  unable  to meet  its
obligations.  In light of the nature of the Fund's  business  and the nature and
amount of its assets,  the possibility of the Fund's  liabilities  exceeding its
assets, and, therefore, a shareholder's risk of personal liability, is remote.

         The Declaration of Trust further provides that the Fund shall indemnify
each of its Trustees and officers  against  liabilities and expenses  reasonably
incurred by them,  in connection  with,  or arising out of, any action,  suit or
proceeding,  threatened against or otherwise  involving such Trustee or officer,
directly or  indirectly,  by reason of being or having been a Trustee or officer
of the Fund.  The  Declaration of Trust does not authorize the Fund to indemnify


                                      B-17
<PAGE>

any Trustee or officer  against any liability to which he or she would otherwise
be subject by reason of or for willful misfeasance,  bad faith, gross negligence
or reckless disregard of such person's duties.

         13.  DETERMINATION OF NET ASSET VALUE

         The net asset value per share of the Fund is determined as of the close
of regular trading on the New York Stock Exchange  (normally 4:00 P.M.,  Eastern
Time) on each day on which the New York Stock Exchange is open for business.  As
of the date of this  Statement  of  Additional  Information,  the New York Stock
Exchange is open for trading  every weekday  except for the following  holidays:
New Year's Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day,
Labor Day,  Thanksgiving Day and Christmas Day. The net asset value per share of
the Fund is also  determined  on any other day in which the level of  trading in
its  portfolio  securities  is  sufficiently  high so that the current net asset
value per share  might be  materially  affected  by  changes in the value of its
portfolio  securities.  On any day in which no purchase orders for the shares of
the Fund become  effective  and no shares are tendered for  redemption,  the net
asset value per share is not determined.

         The net asset  value per share of the Fund is  computed  by taking  the
amount of the value of all of its assets, less its liabilities,  and dividing it
by the number of  outstanding  shares.  Securities  which have not traded on the
date of  valuation  or  securities  for which  sales  prices  are not  generally
reported  are  valued  at the  mean  between  the  last  bid and  asked  prices.
Securities for which no market quotations are readily available (including those
the  trading  of which  has been  suspended)  will be  valued  at fair  value as
determined  in  good  faith  by the  Board  of  Trustees,  although  the  actual
computations  may be made by persons  acting  pursuant to the  direction  of the
Board.

         14.  SYSTEMATIC WITHDRAWAL PLAN

         The  Systematic  Withdrawal  Plan  ("SWP")  is  designed  to  provide a
convenient  method of receiving fixed payments at regular  intervals from shares
of the Fund  deposited  by the  applicant  under this SWP.  You must  deposit or
purchase  for  deposit  with PSC shares of the Fund  having a total value of not
less than $10,000. Periodic payments of $50 or more will be deposited monthly or
quarterly  directly  into a bank account  designated  by you, or will be sent by
check to you, or any person designated by you.  Designation of another person to
receive the checks  subsequent  to opening an account must be  accompanied  by a
signature guarantee.

         Any income dividends or capital gains distributions on shares under the
SWP  will be  credited  to the  SWP  account  on the  payment  date in full  and
fractional shares at the net asset value per share in effect on the record date.

         SWP  payments are made from the  proceeds of the  redemption  of shares
deposited  under the SWP in a SWP account.  To the extent that such  redemptions
for periodic  withdrawals  exceed dividend income reinvested in the SWP account,
such  redemptions  will reduce and may  ultimately  exhaust the number of shares
deposited in the Plan account.  Redemptions are potentially taxable transactions
to shareholders.  In addition,  the amounts received by a shareholder  cannot be
considered as an actual yield or income on his or her investment because part of
such payments may be a return of his or her capital.

         The SWP may be terminated  at any time (1) by written  notice to PSC or
from PSC to the shareholder;  (2) upon receipt by PSC of appropriate evidence of
the  shareholder's  death;  or (3)  when all  shares  under  the SWP  have  been
redeemed. The fees of PSC for maintaining the SWP is paid by the Fund.

         15.  LETTER OF INTENTION

         Purchases of $50,000 or over (excluding any  reinvestments of dividends
and capital gains  distributions)  made within a 13-month  period  pursuant to a
Letter of  Intention  provided by PFD will qualify for a reduced  sales  charge.
Such  reduced  sales charge will be the charge that would be  applicable  to the
purchase of all shares  purchased  during  such  13-month  period  pursuant to a
Letter of Intention had such shares been purchased all at once. See "Information
About Fund Shares" in the Prospectus.  For example,  a person who signs a Letter
of Intention  providing for a total  investment in Fund shares of $50,000 over a
13-month  period would be charged at the 4.50% sales charge rate with respect to
all purchases  during that period.  Should the amount actually  purchased during
the  13-month  period be more or less  than that  indicated  in the  Letter,  an
adjustment  in the sales charge will be made. A purchase not made  pursuant to a
Letter of Intention may be included  thereafter if the Letter is filed within 90
days of such purchase.  Any shareholder may also obtain the reduced sales charge
by including the value (at current offering price) of all his shares in the Fund
and all other Pioneer  mutual funds,  except the Class A shares of Pioneer Money
Market  Trust,  held of record as of the date of his  Letter of  Intention  as a
credit toward determining the applicable scale of sales charge for the shares to
be purchased under the Letter of Intention.

         The  Letter  of  Intention  authorizes  PSC to escrow  shares  having a
purchase price equal to 5% of the stated  investment in the Letter of Intention.
A Letter of Intention is not a binding obligation upon the investor to purchase,
or the Fund to sell, the full amount  indicated and the investor should read the
provisions  of the Letter of  Intention  contained  in the  Account  Application
carefully.

         16.  INVESTMENT RESULTS

         Quotations, Comparisons, and General Information

         From  time to  time,  in  advertisements,  in sales  literature,  or in
reports to  shareholders,  the past  performance  of the Fund may be illustrated
and/or  compared  to  that  of  other  mutual  funds  with  similar   investment
objectives,  and to stock or other  relevant  indices.  For example,  the Fund's
performance may be compared to rankings prepared by Lipper Analytical  Services,
Inc.,  a widely  recognized  independent  service  which  monitors  mutual  fund
performance;  the  Standard & Poor's 500 Stock  Index ("S&P  500"),  an index of
unmanaged  groups  of  common  stock;  or the Dow Jones  Industrial  Average,  a
recognized unmanaged index of common stocks of 30 industrial companies listed on
the New York Stock  Exchange;  or the Frank  Russell  Indexes  ("Russell  1000,"
"2000," "2500," "3000") and Wilshire Total Market Value Index ("Wilshire 5000"),
recognized unmanaged indexes of broad-based common stocks.

         In addition, the performance of the Fund may be compared to alternative
investment  or savings  vehicles  and/or to indexes or  indicators  of  economic
activity,  e.g., inflation or interest rates.  Performance rankings and listings
reported in newspapers or national business and financial publications,  such as
Barron's,  Business Week, Consumers Digest,  Consumer Reports,  Financial World,
Forbes,  Investors Business Daily,  Kiplinger's Personal Finance Magazine, Money
Magazine,  New York Times,  Smart Money, USA Today,  U.S. News and World Report,
The Wall  Street  Journal  and Worth may also be cited (if the Fund is listed in
any such  publication) or used for comparison,  as well as performance  listings

         Standardized Average Annual Total Returns
         Quotations and Other Performance Quotations

         One of the  methods  used to measure the Fund's  performance  is "total
return." "Total return" will normally  represent the percentage  change in value
of an account,  or of a hypothetical  investment in the Fund, over any period up
to the lifetime of the Fund. Total return  calculations  will usually assume the
reinvestment  of all  dividends  and  capital  gains  distributions  and will be
expressed as a percentage  increase or decrease from an initial  value,  for the
entire period or for one or more  specified  periods  within the entire  period.
Total  return  percentages  for  periods  of less than one year will  usually be
annualized;  total  return  percentages  for  periods  longer than one year will
usually be  accompanied  by total  return  percentages  for each year within the
period and/or the average  annual  compounded  total return for the period.  The
income and capital  components  of a given return may be separated and portrayed
in a  variety  of ways in  order  to  illustrate  their  relative  significance.
Performance  may also be portrayed in terms of cash or investment  values.  Past
performance cannot guarantee any particular future result.

         Generally,  performance illustrations will include or be accompanied by
the Fund's  average  annual total return over the prior one year,  five year and
ten year periods.  The average annual total return ("T") is computed by equating
the  value  at the  end of  the  period  ("ERV")  with  a  hypothetical  initial
investment  of  $1,000  ("P")  over a period  of years  ("n")  according  to the
following formula specified by the SEC: P(1+T)n = ERV.

         These  computations  will assume the  deduction  of the  maximum  sales
charge of 5.75% from the initial  investment,  the reinvestment of dividends and
distributions  at net asset value on the  appropriate  dates and a redemption of
the account at the end of the period.

         The  average  annual  compounded  total  return  of the  Fund  for  the
one-year, five-year, ten-year and life-of-Fund periods ending December 31, 1994,
was -6.30%, 5.96%, 11.19% and 12.58%, respectively.

         The Fund may also present,  from time to time,  historical  information
depicting  the value of a  hypothetical  account  over the time  period from the
Fund's  inception  in 1928 until the present.  The Fund also may depict  summary
results of  assumed  investments  in the Fund for each of the  ten-calendar-year
periods  in the Fund's  history  and for the  ten-year  periods  which  began at
recognized  market highs or ended at recognized  market lows. An example of this
historical  information  describing various  performance  characteristics of the
Fund from 1928 until the  present is  contained  under the  caption  "Investment
Results" in this Statement of Additional Information.

         In presenting  investment results, the Fund may also include references
to certain  financial  planning  concepts,  including (a) an investor's  need to
evaluate his financial  assets and  obligations to determine how much to invest;
(b) his need to analyze the objectives of various investments to determine where
to invest;  and (c) his need to analyze his time frame for future  capital needs
to determine how long to invest. The investor controls these three factors,  all
of which affect the use of investments in building assets.

S&P 500 *
   
This index is a readily available, carefully constructed,  market value weighted
benchmark  of common  stock  performance.  Currently,  the S&P  Composite  Index
includes 500 of the largest stocks (in terms of stock market value) in the U.S.;
prior to March 1957 it consisted of 90 of the largest stocks.
    

DOW JONES INDUSTRIAL AVERAGE *
This is a total return index based on the performance of 30 blue chip stocks.

SMALL CAPITALIZATION STOCKS *
This index is a market value  weighted  index of the ninth and tenth  deciles of
the New York Stock  Exchange  (NYSE),  plus stocks listed on the American  Stock
Exchange (AMEX) and over-the-counter  (OTC) with the same or less capitalization
as the upper bound of the NYSE ninth decile.

INFLATION *
The  Consumer  Price  Index  for All Urban  Consumers  (CPI-U),  not  seasonally
adjusted, is used to measure inflation,  which is the rate of change of consumer
goods prices.  Unfortunately,  the  inflation  rate as derived by the CPI is not
measured  over the same period as the other asset  returns.  All of the security
returns are measured  from one  month-end to the next  month-end.  CPI commodity
prices are collected during the month.  Thus,  measured  inflation rates lag the
other  series  by about  one-half  month.  Prior to  January  1978,  the CPI (as
compared with CPI-U) was used.  Both inflation  measures are  constructed by the
U.S. Department of Labor, Bureau of Labor Statistics, Washington, DC.

S&P/BARRA INDEXES *
"The S&P/BARRA  Growth and Value Indexes are  constructed by dividing the stocks
in the S&P 500  Index  according  to  price-to-book  ratios.  The  Growth  Index
contains stocks with higher  price-to-book  ratios, and the Value Index contains
stocks with lower price-to-book  ratios. Both indexes are market  capitalization
weighted."

LONG-TERM MUNICIPAL BOND PORTFOLIO *
For 1926-1984,  returns are calculated  form yields on 20-year prime issues from
Solomon  Brothers'  Analytical  Record of Yields  and Yields  Spreads,  assuming
coupon equals previous year-end yield and a 20-year maturity.  For 1985-present,
returns are  calculated  using Moody's Bond Record,  using the December  average
municipal yield as the  beginning-of-following  year coupon (average of Aaa, Aa,
A, Baa grades).

LONG-TERM CORPORATE BONDS *
For  1969-1991,  corporate  bond total  returns are  represented  by the Salomon
Brothers Long-Term  High-Grade  Corporate Bond Index. Since most large corporate
bond  transactions  take place over the  counter,  a major dealer is the natural
source of these data. The index includes  nearly all Aaa- and Aa-rated bonds. If
a bond is  downgraded  during a  particular  month,  its return for the month is
included in the index before removing the bond from future portfolios.

Over  1926-1968  the total  returns  were  calculated  by  summing  the  capital
appreciation returns and the income returns. For the period 1946-1968,  Ibbotson
and Sinquefield  backdated the Salomon Brothers' index,  using Salomon Brothers'
monthly  yield  data with a  methodology  similar  to that used by  Salomon  for
1969-1991. Capital appreciation returns were calculated from yields assuming (at


                                      B-26
<PAGE>

the beginning of each monthly holding period) a 20-year  maturity,  a bond price
equal to par,  and a  coupon  equal to the  beginning-of-period  yield.  For the
period 1926-1945, the Standard and Poor's monthly High-Grade Corporate Composite
yield data were used,  assuming a 4 percent coupon and a 20-year  maturity.  The
conventional  present-value  formula  for  bond  price  for  the  beginning  and
end-of-month  prices was used.  (This formula is presented in Ross,  Stephen A.,
and Randolph W. Westerfield,  Corporate Finance, Times Mirror/Mosby,  St. Louis,
1990, p. 97 ["Level-Coupon Bonds"].) The monthly income return was assumed to be
one-twelfth the coupon.

LONG-TERM GOVERNMENT BOND TOTAL RETURN *
The  total  returns  on  long-term  government  bonds  from  1977  to  1991  are
constructed  with data from The Wall Street Journal.  Over  1926-1976,  data are
obtained  from the  Government  bond file at the Center for Research in Security
Prices (CRSP), Graduate School of Business,  University of Chicago. Each year, a
one-bond  portfolio  with a term of  approximately  20  years  and a  reasonably
current  coupon  was used,  and whose  returns  did not  reflect  potential  tax
benefits,  impaired  negotiability,  or special  redemption or call  privileges.
Where  callable  bonds had to be used,  the term of the bond was assumed to be a
simple  average of the maturity and first call dates minus the current date. The
bond was "held" for the calendar year and returns were  computed.  Total returns
for  1977-1991 are  calculated  as the change in the flat price or  and-interest
price.

INTERMEDIATE-TERM GOVERNMENT BONDS TOTAL RETURN *
Total  returns  of the  intermediate-term  government  bonds for  1977-1991  are
calculated from The Wall Street Journal prices,  using the change in flat price.
Returns from 1934-1986 are obtained from the CRSP Government Bond File.

Each year,  one-bond  portfolios  are formed,  the bond  chosen is the  shortest
noncallable  bond with a maturity not less than 5 years, and this bond is "held"
for the  calendar  year.  Monthly  returns are  computed.  (Bonds with  impaired
negotiability or special redemption  privileges are omitted, as are partially or
fully  tax-exempt  bonds starting with 1943.) From  1934-1942,  almost all bonds
with maturities near 5 years were partially or full tax-exempt and were selected
using the rules described  above.  Personal tax rates were generally low in that
period,  so that yields on  tax-exempt  bonds were  similar to yields on taxable
bonds. From 1926-1933, there are few bonds suitable for construction of a series
with a 5-year  maturity.  For this period,  five year bond yield  estimates  are
used.

U.S. (30 DAY) TREASURY BILL TOTAL RETURNS *
For the U.S. Treasury bill index, data from The Wall Street Journal are used for
1977-1991;  the CRSP U.S.  Government  Bond File is the source until 1976.  Each
month a one-bill  portfolio  containing the  shortest-term  bill having not less
than one month to maturity is constructed. (The bill's original term to maturity
is not relevant.) To measure holding period returns for the one-bill  portfolio,
the bill is priced as of the last trading day of the previous  month-end  and as
of the last trading day of the current month.
