PIONEER  VARIABLE  CONTRACTS  TRUST  (the  Fund)  is  an  open-end,   management
investment  company  primarily  designed  to  provide  investment  vehicles  for
variable annuity and variable life insurance contracts  (Variable  Contracts) of
various insurance companies.

The Fund currently offers these Portfolios:

INTERNATIONAL  GROWTH  PORTFOLIO  seeks  long-term  growth of capital  primarily
through  investments in non- United States (U.S. ) equity securities and related
depositary receipts.

CAPITAL  GROWTH  PORTFOLIO  seeks  capital  appreciation  through a  diversified
portfolio of securities consisting primarily of common stocks.

REAL ESTATE GROWTH PORTFOLIO seeks long-term growth of capital primarily through
investments in the securities of real estate investment trusts (REITs) and other
real estate  industry  companies.  Current income is the  Portfolio's  secondary
investment objective.

EQUITY-INCOME  PORTFOLIO  seeks current  income and long-term  capital growth by
investing  in  a  portfolio  of  income-producing   equity  securities  of  U.S.
corporations.  The Portfolio's goal is to achieve a current dividend yield which
exceeds the published composite yield of the securities  comprising the Standard
& Poor's 500 Composite Stock Price Index.

BALANCED  PORTFOLIO seeks capital growth and current income by actively managing
investments in a diversified portfolio of equity securities and bonds.

SWISS FRANC BOND  PORTFOLIO  seeks to approximate  the  performance of the Swiss
franc relative to the U.S. dollar while earning a reasonable level of income.

AMERICA  INCOME  PORTFOLIO  seeks  as  high a  level  of  current  income  as is
consistent  with the  preservation  of capital.  The  Portfolio  invests in U.S.
Government Securities and in "when issued" commitments and repurchase agreements
with respect to such securities.

MONEY MARKET PORTFOLIO seeks current income  consistent with preserving  capital
and providing  liquidity.  The Portfolio  seeks to maintain a stable $1.00 share
price;  HOWEVER,  THERE CAN BE NO  ASSURANCE  THAT A $1.00  SHARE  PRICE WILL BE
MAINTAINED.

PORTFOLIO  RETURNS AND SHARE PRICES FLUCTUATE AND THE VALUE OF YOUR ACCOUNT UPON
REDEMPTION  MAY BE  MORE  OR  LESS  THAN  YOUR  PURCHASE  PRICE.  SHARES  IN THE
PORTFOLIOS ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR ENDORSED BY, ANY
BANK OR OTHER DEPOSITORY  INSTITUTION,  ARE NOT FEDERALLY INSURED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER GOVERNMENT
AGENCY AND ARE NOT  GUARANTEED  BY THE  UNITED  STATES  GOVERNMENT.  THERE IS NO
ASSURANCE THAT A PORTFOLIO WILL ACHIEVE ITS OBJECTIVE.

Investors  considering the purchase of shares of any Portfolio  should read this
Prospectus before investing.  It is designed to provide you with information and
help you decide if the goal of one or more of the  Portfolios  matches your own.
Retain this document for future reference.

Shares of each Portfolio may be purchased  primarily by the separate accounts of
insurance companies,  for the purpose of funding Variable Contracts.  Particular
Portfolios may not be available in your state due to various  insurance or other
regulations.  Please check with your insurance company for available Portfolios.
Inclusion of a Portfolio in this Prospectus which is not available in your state
is not to be  considered  a  solicitation.  This  Prospectus  should  be read in

I. HIGHLIGHTS
PIONEER VARIABLE CONTRACTS TRUST

Pioneer Variable Contracts Trust (the Fund) is an open-end management investment
company that  currently  consists of eight  distinct  Portfolios.  Shares of the
Portfolios  are  offered  primarily  to holders of  insurance  company  variable
annuity and variable life  insurance  contracts  (Variable  Contracts).  You may
obtain  certain tax  benefits by  purchasing a Variable  Contract  (refer to the
prospectus of your insurance  company's separate account for a discussion of the
tax benefits).

Each  Portfolio  has its own distinct  INVESTMENT  OBJECTIVE  AND  POLICIES.  In
striving to meet its  objective,  each  Portfolio  will face the  challenges  of
changing  business,  economic  and  market  conditions.  Each  Portfolio  offers
different  levels of potential  return and will experience  different  levels of
risk.

No single  Portfolio  constitutes a complete  investment  plan. Each Portfolio's
share price (except as described  below for Money Market  Portfolio),  yield and
total return will  fluctuate  and an investment in a Portfolio may be worth more
or less than your original cost when shares are redeemed. Money Market Portfolio
seeks to  maintain  a  constant  $1.00  share  price  although  there  can be no
assurance it will do so.

Pioneering  Management  Corporation  (Pioneer) is the investment adviser to each
Portfolio.  Each Portfolio pays a fee to its investment adviser for managing the
Portfolio's  investments and business  affairs.  For a discussion of these fees,
please see "FUND MANAGEMENT FEES AND OTHER EXPENSES."

Each Portfolio  complies with various  insurance  regulations.  Please read your
insurance  company's separate account  prospectus for more specific  information
relating  to  insurance  regulations  and  instructions  on how to invest in and
redeem  from each  Portfolio.  For a general  discussion  of how to buy and sell
Portfolio shares, see "SHAREHOLDER INFORMATION" in this Prospectus.

II. HOW THE FUND WORKS

INVESTMENT OBJECTIVES AND POLICIES

The Fund's Portfolios are designed to serve as investment vehicles primarily for
Variable  Contracts  of insurance  companies.  The Fund  currently  offers eight
Portfolios with different investment objectives and policies which are described
below. Each Portfolio's  investment  objective is fundamental and can be changed
only by vote of a majority of the outstanding shares of the Portfolio. All other
investment  policies of each Portfolio are  nonfundamental and may be changed by
the Fund's Trustees without shareholder  approval.  There is no assurance that a
Portfolio will achieve its investment objective.

Each  Portfolio  may  invest  up to  100%  of its  total  assets  in  short-term
investments  for  temporary  defensive  purposes.  A  Portfolio  will  assume  a
temporary  defensive  posture only when economic and other factors are such that
Pioneer believes there to be extraordinary risks in being substantially invested
in the securities in which the Portfolio normally  concentrates its investments.
Refer to the APPENDIX for a description of short-term investments.

INTERNATIONAL  GROWTH  PORTFOLIO  seeks  long-term  growth of capital  primarily
through  investments  in  non-U.S.  equity  securities  and  related  depositary
receipts.  Non-U.S.  equity securities are equity securities of issuers that are
organized and have principal  offices in foreign  countries.  For information on
depositary receipts, please refer to the APPENDIX.

Normally,  at least 80% of the  Portfolio's  total  assets  will be  invested in
non-U.S.  equity securities and related depositary  receipts.  The Portfolio may
not invest more than 25 % of its total assets in  securities of issuers from any
one country except Japan or the United Kingdom.  Also, with the exception of the
Japanese  yen, the British  pound and the U.S.  dollar,  no more than 25% of the
Portfolio's  total assets may be denominated in the currency of any one country.
Substantial investments in Japan and the United Kingdom or their currencies will
subject the Portfolio to the risks associated with changing economic, market and
social  conditions  in  Japan  and  the  United  Kingdom.  Refer  to  "RISKS  OF
INTERNATIONAL INVESTMENTS" for more information.


The  Portfolio is managed in accordance  with  Pioneer's  "investing  for value"
investment  philosophy.  This  approach  consists of  developing  a  diversified
portfolio of securities consistent with the Portfolio's investment objective and
selected  primarily on the basis of Pioneer's  judgment that the securities have
an underlying value, or potential value, which exceeds their current prices. The
analysis and  quantification of the economic worth, or "value," of an individual
company reflects Pioneer's  assessment of the company's assets and the company's
prospects for earnings growth over the next three to five years.  Pioneer relies
primarily on the knowledge,  experience and judgment of its own research  staff,
but also  receives  and uses  information  from a variety  of  outside  sources,
including brokerage firms, electronic databases,  specialized research firms and
technical journals.


When  allocating  the  Portfolio's  investments  among  geographic  regions  and
individual countries,  Pioneer considers various criteria, such as prospects for
relative  economic  growth  among  countries,   expected  levels  of  inflation,
government  policies  influencing  business  conditions,  and  the  outlook  for
currency  relationships.  Pioneer  currently  expects  to  invest  most  of  the
Portfolio's  assets in  securities  of  issuers  located in  countries  such as:
Australia,  Canada, Hong Kong, Japan, Malaysia,  Mexico,  Singapore,  the United
Kingdom and the other developed  countries of Western Europe.  The Portfolio may
also invest in the  securities  of issuers  located in countries  with  emerging
markets such as: Algeria, Argentina, Bangladesh, Brazil, Bulgaria, Chile, China,
Colombia,  Czech  Republic,  Ecuador,  Egypt,  Ghana,  Greece,  Hungary,  India,
Indonesia,  Israel, Jamaica, Jordan, Kenya, Kuwait, Morocco, Nigeria,  Pakistan,
Peru, the Philippines,  Poland, Portugal, Russia, South Africa, South Korea, Sri
Lanka,  Taiwan,  Thailand,  Turkey,  Uruguay,  Venezuela,  Vietnam and Zimbabwe.
Normally,  at least 65% of the  Portfolio's  total assets will be invested in at
least three different non-U.S.  countries.  In addition,  most of the securities
purchased by the Portfolio will be denominated in foreign currencies.

Pioneer  may  normally  invest  up to 20% of the  Portfolio's  total  assets  in
short-term debt  securities,  including  certain  securities  issued by U.S. and
non-U.S.  governments  and  banks,  and debt  securities  of  non-U.S.  and U.S.
companies. 

<PAGE>

The  Portfolio  will not purchase  lower rated debt  securities  or unrated debt
securities of comparable quality, but up to 5% of its net assets may be invested
in  such  securities  as a  result  of  credit  quality  downgrades.  See  "RISK
CONSIDERATIONS  - RISKS OF MEDIUM  AND LOWER  RATED  DEBT  SECURITIES."  Pioneer
expects that  opportunities  for long-term growth of capital will come primarily
from the Portfolio's  investments in equity securities,  including common stock,
securities  such as warrants or rights that are  convertible  into common stock,
preferred stock and depositary receipts for such securities.

OTHER  INVESTMENT  PRACTICES.  Refer  to the  APPENDIX  for  information  on the
Portfolio's  possible  use  of  illiquid  investments,   restricted  securities,
warrants,  options and futures  contracts,  forward  foreign  currency  exchange
contracts and repurchase agreements, and its ability to lend securities.


CAPITAL  GROWTH  PORTFOLIO  seeks  capital  appreciation  through a  diversified
portfolio of securities  consisting  primarily of common  stocks.  Normally,  at
least 80% of the  Portfolio's  assets will be  invested in common  stocks and in
securities  with common stock  characteristics,  such as  convertible  bonds and
preferred stocks.  In selecting  individual equity securities to be purchased by
the  Portfolio,  Pioneer uses the  "investing  for value"  approach as described
above for International Growth Portfolio.


The Portfolio  may invest up to 25% of its total assets in non-U.S.  securities.
Investments in non-U.S.  securities are not currently  expected to exceed 10% of
the  Portfolio's  total  assets.  For a discussion of  international  investing,
please see "RISKS OF INTERNATIONAL INVESTMENTS."

OTHER  INVESTMENT  PRACTICES.  Refer  to the  APPENDIX  for  information  on the
Portfolio's  possible  use  of  repurchase  agreements,   illiquid  investments,
restricted securities,  options,  futures contracts and forward foreign currency
exchange contracts, and its ability to lend securities.

REAL ESTATE GROWTH PORTFOLIO seeks long-term growth of capital primarily through
investments in the equity  securities of real estate  investment  trusts (REITs)
and other real estate  industry  companies.  Current  income is the  Portfolio's
secondary investment  objective.  The Portfolio will invest in a non-diversified
portfolio  consisting  primarily  of equity  securities  of REITs and other real
estate  industry  companies and, to a lesser extent,  in debt securities of such
companies  and in  mortgage-backed  securities.  Normally,  at least  75% of the
Portfolio's assets will be invested in equity securities of REITs and other real
estate industry companies.  See "RISKS ASSOCIATED WITH THE REAL ESTATE INDUSTRY"
and "RISKS ASSOCIATED WITH REAL ESTATE INVESTMENT TRUSTS."

A REAL ESTATE INDUSTRY COMPANY is defined as a company that derives at least 50%
of its gross revenues or net profits from either (a) the ownership, development,
construction,  financing,  management  or  sale  of  commercial,  industrial  or
residential  real estate or (b) products or services  related to the real estate
industry like building supplies or mortgage servicing.  The equity securities of
real estate  industry  companies in which the Portfolio  will invest  consist of
common stock,  shares of beneficial interest of REITs and securities with common
stock  characteristics,  such as preferred stock and debt securities convertible
into common stock.

The  Portfolio  may also  invest  up to 25% of its  total  assets  in:  (a) debt
securities of real estate industry companies,  (b)  mortgage-backed  securities,
such as mortgage  pass-through  certificates,  real estate  mortgage  investment
conduit (REMIC) certificates and collateralized  mortgage obligations (CMOs) and
(c)  short-term   investments.   See  "RISKS  ASSOCIATED  WITH   MORTGAGE-BACKED
SECURITIES."  The  Portfolio may invest up to 5% of its net assets in equity and
debt securities of non-U.S.  real estate companies.  See "RISKS OF INTERNATIONAL
INVESTMENTS."

Pioneer will invest no more than 5% of the Portfolio's net assets in lower rated
debt  securities or unrated debt  securities of  comparable  quality.  See "RISK
CONSIDERATIONS - RISKS OF MEDIUM AND LOWER RATED DEBT SECURITIES."

The  Portfolio  will  purchase  the  securities  of REITs and other real  estate
industry companies when, in Pioneer's judgment, their market price appears to be
less than their  fundamental  value  and/or  which offer a high level of current
income  consistent  with  reasonable  investment  risk.  In  selecting  specific
investments,  Pioneer  will  attempt to  identify  securities  with  significant
potential for appreciation relative to their downside exposure and/or which have
a timely record and high level of interest or dividend payments. In making these
determinations, Pioneer will take into

<PAGE>

account  price/earnings  ratios,  cash flow, the  relationship of asset value to
market price of the securities,  interest or dividend  payment history and other
factors  which it may determine  from time to time to be relevant.  Pioneer will
attempt to allocate the Portfolio's  investments  across regional  economies and
property types.

Unlike the other  Portfolios,  Real Estate Growth Portfolio is a non-diversified
mutual  fund  under the  Investment  Company  Act of 1940 (the 1940  Act).  As a
non-diversified  mutual fund,  the  Portfolio may be more  susceptible  to risks
associated  with a single  economic,  political or regulatory  occurrence than a
diversified fund.

OTHER  INVESTMENT  PRACTICES.  Refer to the APPENDIX for  information  about the
Portfolio's  possible  use  of  repurchase  agreements,   illiquid  investments,
restricted securities, options and futures, and its ability to lend securities.

EQUITY-INCOME  PORTFOLIO  seeks  current  income and  long-term  capital  growth
primarily  by  investing  in the  income-producing  equity  securities  of  U.S.
corporations.  The Portfolio's goal is to achieve a current dividend yield which
exceeds the published composite yield of the securities  comprising the Standard
& Poor's 500 Composite Stock Price Index (S&P 500 Index).

Normally,  at least 80% of the  Portfolio's  total  assets  will be  invested in
income-producing  common or preferred  stock.  The remainder of the  Portfolio's
assets may be  invested  in debt  securities,  most of which are  expected to be
convertible  into  common  stock.  Pioneer  will  invest  no more than 5% of the
Portfolio's net assets in lower rated debt securities or unrated debt securities
of  comparable  quality.  See "RISK  CONSIDERATIONS  - RISKS OF MEDIUM AND LOWER
RATED DEBT SECURITIES."


The  Portfolio is managed in accordance  with  Pioneer's  "investing  for value"
investment  philosophy as described above for  International  Growth  Portfolio.
This  approach  consists of  developing a  diversified  portfolio of  securities
consistent with the Portfolio's  investment objectives and selected primarily on
the basis of Pioneer's judgment that the securities have an underlying value, or
potential value, which exceeds their current prices.


OTHER  INVESTMENT  PRACTICES.  Refer  to the  APPENDIX  for  information  on the
Portfolio's  possible  use of  repurchase  agreements  and its  ability  to lend
securities.

BALANCED  PORTFOLIO seeks capital growth and current income by actively managing
investments in a diversified portfolio of equity securities and bonds. Normally,
equity  securities and bonds will each  represent 35% to 65% of the  Portfolio's
assets.

The assets of the Portfolio  allocated to equity  securities will be invested in
common  stocks and in  securities  with common  stock  characteristics,  such as
convertible bonds and preferred stocks. Normally,  Portfolio assets allocated to
bonds will be invested in (1) debt securities  rated "A" or higher by Standard &
Poor's Ratings Group (S&P) or Moody's Investors  Service,  Inc. (Moody's) or, if
unrated,  judged by Pioneer to be of comparable quality, (2) commercial paper of
comparable  quality  and  (3)  U.S.  Government  Securities,  GNMA  Certificates
(described below) and CMOs. The Portfolio may, however,  invest up to 20% of its
total assets in debt securities that are rated "BBB" by S&P or "Baa" by Moody's,
or, if unrated, judged by Pioneer to be of comparable quality, and in commercial
paper that is of comparable  quality.  See "RISKS OF MEDIUM AND LOWER RATED DEBT
SECURITIES."  Although the Portfolio  intends to be fully  invested,  normally a
portion of the  Portfolio's  total assets may be invested in cash and short-term
investments. Refer to the APPENDIX for a description of short-term investments.

Consistent with its investment objectives, the Portfolio may invest up to 25% of
its total assets in non-U.S.  securities and related  forward  foreign  currency
exchange contracts. For a further discussion of international investing,  please
see "RISKS OF INTERNATIONAL INVESTMENTS."

The allocation of the  Portfolio's  assets between stocks and bonds will vary in
response to conclusions drawn from Pioneer's  continual  assessment of business,
economic and market conditions. The mix of equity securities,  bonds, short-term
investments and cash may be held in whatever  proportions Pioneer determines are
necessary for defensive purposes.
<PAGE>

OTHER  INVESTMENT  PRACTICES.  Refer  to the  APPENDIX  for  information  on the
Portfolio's  possible  use of  repurchase  agreements  and its  ability  to lend
securities. The Portfolio will not invest in futures or options, except that the
Portfolio may use forward foreign currency  exchange  contracts and purchase and
sell options and futures contracts relating to foreign currencies.


SWISS FRANC BOND  PORTFOLIO  seeks to approximate  the  performance of the Swiss
franc  relative to the U.S.  dollar while earning a reasonable  level of income.
The  Portfolio  was  developed  by  Pioneer  with the  assistance  of JML  Swiss
Investment Counsellors, A.G., a Swiss financial consultant.


   
Normally,  the  Portfolio  invests  at  least  65% of its  total  assets  in (1)
government and corporate debt  securities  that are  denominated in Swiss francs
and (2)  combinations of forward foreign  currency  exchange  contracts and debt
securities  that  are  not  denominated  in  Swiss  francs   ("non-Swiss   franc
securities") designed to link the value of the investment in the non-Swiss franc
security to the  performance  of the Swiss  franc.  Pioneer  expects  that these
combination  investments  generally  will  represent  no  more  than  25% of the
Portfolio's  total assets.  The  Portfolio's  investments in debt securities are
investment  grade (I.E.,  rated "BBB",  "Baa" or higher by S&P or Moody's or, if
unrated,  determined by Pioneer to be of comparable  quality).  The  Portfolio's
weighted  average  maturity  normally will not exceed three years, but may be as
long as 5 years if Pioneer determines that a longer weighted average maturity is
appropriate in response to existing or expected market conditions.
    

The  Portfolio  may  invest up to 35% of its total  assets in  investment  grade
commercial  paper,  bank obligations and money market  instruments  which may be
denominated in the Swiss franc or other  currencies.  Normally,  at least 50% of
the Portfolio's  investments will be denominated in Swiss francs.  An investment
in the  Portfolio may  effectively  hedge a  diversified  investment  program by
offering protection against declines in the value of the U.S. dollar relative to
the Swiss franc.


OTHER  INVESTMENT  PRACTICES.  Refer  to the  APPENDIX  for  information  on the
Portfolio's possible use of illiquid investments, restricted securities, futures
and options  contracts,  forward  currency  exchange  contracts  and  repurchase
agreements, and its ability to lend securities.


AMERICA  INCOME  PORTFOLIO  seeks  as  high a  level  of  current  income  as is
consistent with the preservation of capital.  Normally, the Portfolio invests in
U.S.  Government  Securities  and in  "when-issued"  commitments  and repurchase
agreements with respect to such securities.

The Portfolio's  investments in U.S. Governments  Securities may include certain
mortgage-backed  securities,  such as  mortgage  pass-through  certificates  and
collateralized   mortgage  obligations  (CMOs).  See  the  APPENDIX  and  "RISKS
ASSOCIATED WITH MORTGAGE-BACKED SECURITIES."

U.S.  GOVERNMENT  SECURITIES  are debt  securities  issued or  guaranteed  as to
principal and interest by the U.S.  Treasury or by an agency or  instrumentality
of the U.S.  Government.  Not all U.S.  Government  Securities are backed by the
full faith and credit of the United States.  For example,  securities  issued by
the Federal Farm Credit  Bank,  the Student Loan  Marketing  Association  or the
Federal  National  Mortgage  Association  are supported by the agency's right to
borrow money from the U.S.  Treasury  under  certain  circumstances.  Securities
issued by the  Federal  Home Loan Bank are  supported  only by the credit of the
agency.  There is no guarantee that the U.S. Government will support these types
of  securities,  and  therefore  they  involve  more risk  than U.S.  Government
Securities that are backed by the full faith and credit of the United States.

U.S.  GOVERNMENT  SECURITIES that are backed by the full faith and credit of the
United States include (1) U.S. Treasury obligations,  which differ only in their
interest rates, maturities and times of issuance, and (2) obligations of varying
maturities issued or guaranteed by certain agencies and instrumentalities of the
U.S. Government, such as mortgage participation certificates (GNMA Certificates)
guaranteed by the Government  National Mortgage  Association  (GNMA) and Federal
Housing   Administration   (FHA)   debentures,   for  which  the  U.S.  Treasury
unconditionally  guarantees  payment of  principal  and  interest.  Although the
payment when due of interest and principal on these  securities is backed by the
full faith and credit of the United  States,  this  guarantee does not extend to
the market  value of these  securities.  The net asset value of the  Portfolio's
shares will fluctuate accordingly.
<PAGE>

The  Portfolio  is free to take  advantage  of the  entire  range of  maturities
offered by U.S. Government  Securities and the average maturity of the Portfolio
may vary significantly.  Under normal  circumstances,  however,  the Portfolio's
dollar-weighted average portfolio maturity is not expected to exceed 20 years.

GNMA CERTIFICATES.  The Portfolio may invest all or any portion of its assets in
GNMA Certificates but it is not obligated to do so; the portion of its assets so
invested will vary with Pioneer's view of the relative yields and values of GNMA
Certificates  compared to U.S.  Treasury  obligations and other U.S.  Government
Securities. GNMA Certificates are mortgage-backed securities which evidence part
ownership of a pool of mortgage loans. The GNMA Certificates which the Portfolio
may  purchase  are  the  "modified  pass-through"  type.  Modified  pass-through
certificates  entitle the holder to receive all  principal  and interest owed on
the mortgages in the pool,  net of fees paid to the issuer and GNMA,  regardless
of whether or not the mortgagor actually makes the payment.

GNMA  Certificates may offer yields higher than those available from other types
of U.S. Government  Securities.  However,  because of principal  prepayments and
foreclosures  with respect to mortgages in the underlying pool, they may be less
effective  than other types of securities as a means of "locking in"  attractive
long-term  interest rates.  Prepayments  generally can be invested only at lower
interest rates.

"WHEN-ISSUED"  GNMA CERTIFICATES.  When-issued or delayed delivery  transactions
arise when  securities  are purchased or sold by the Portfolio  with payment and
delivery  taking place in the future in order to secure what is considered to be
an advantageous  price and yield which is fixed at the time of entering into the
transaction.  However,  the  yield on a  comparable  GNMA  Certificate  when the
transaction  is consummated  may vary from the yield on the GNMA  Certificate at
the time that the when-issued or delayed  delivery  transaction was made.  Also,
the market value of the  when-issued or delayed  delivery GNMA  Certificate  may
increase  or  decrease  as a  result  of  changes  in  general  interest  rates.
When-issued and delayed delivery  transactions involve risk of loss if the value
of a GNMA Certificate declines before the settlement date.

The value of when-issued GNMA Certificate  purchase commitments at any time will
not exceed the value of the Portfolio's  assets invested in U.S.  Treasury bills
(I.E., U.S. Treasury  obligations with maturities of one year or less) and other
debt  securities  having  remaining  maturities  of less  than  six  months.  In
addition,  the  Portfolio's  aggregate  investments  in  when-issued  or delayed
delivery commitments and repurchase agreements may not exceed 25% of its assets.


OTHER  INVESTMENT  PRACTICES.  Refer  to the  APPENDIX  for  information  on the
Portfolio's  possible  use of  repurchase  agreements  and its  ability  to lend
securities.


MONEY MARKET PORTFOLIO seeks current income  consistent with preserving  capital
and  providing  liquidity.  The  Portfolio  should be  considered as a temporary
investment  rather than as an income or cash  management  vehicle.  Pioneer will
invest the  Portfolio's  assets in the  following  types of  high-quality  money
market instruments.

         o  U.S. Government Securities.

         o  Obligations of U.S. banks and their non-U.S.  branches,  savings and
            loan  associations  with total  assets in excess of $1  billion  and
            certain smaller banks and savings and loan  associations  satisfying
            criteria described in the Statement of Additional Information. These
            obligations   include   certificates   of   deposit   and   bankers'
            acceptances.

         o  Commercial Paper: that is, short-term  unsecured promissory notes of
            corporations,  including  variable amount master demand notes rated,
            on the date of  investment,  A-1 by S&P or P-1 by  Moody's,  or,  if
            unrated, issued by companies having outstanding debt rated AAA or AA
            by S&P or Aaa or Aa by Moody's.
<PAGE>

         o  Short-Term Corporate Debt Securities:  that is, bonds and debentures
            with  no  more  than  397  days  remaining  to  maturity  at date of
            settlement and rated AAA or AA by S&P or Aaa or Aa by Moody's.

The  Portfolio may enter into  repurchase  agreements  with  approved  banks and
broker-dealers  for  periods not to exceed  seven days and only with  respect to
U.S.  Government  Securities that,  throughout the period, have a value at least
equal to the amount of the repurchase agreement (including accrued interest). No
more than 25% of the  Portfolio's  assets will be invested in any one  industry,
except that there is no percentage limitation on investments in bank obligations
or U.S. Government Securities.

Many of the instruments in which Money Market Portfolio may invest are described
in the APPENDIX.

QUALITY.  Money Market Portfolio may purchase only high quality  securities that
Pioneer believes present minimal credit risks. To be considered high quality,  a
security must be rated, in accordance  with applicable  rules, in one of the two
highest categories for short-term securities by the major rating services,  such
as S&P's or  Moody's  (or by one,  if only one  rating  service  has  rated  the
security), or, if unrated, judged to be of equivalent quality by Pioneer.

High  quality  securities  are  divided  into  "first  tier" and  "second  tier"
securities.  FIRST TIER SECURITIES have received the highest rating (e.g., S&P's
A-1 rating) from at least two rating services (or one, if only one has rated the
security).  SECOND TIER SECURITIES have received  ratings within the two highest
categories  (e.g.,  S&P's A-1 or A-2) from at least two rating services (or one,
if  only  one  has  rated  the  security),  but do not  qualify  as  first  tier
securities.  If a security  has been  assigned  different  ratings by  different
rating  services,  at least two rating  services  must have  assigned the higher
rating in order for Pioneer to determine eligibility on the basis of that higher
rating. Based on procedures adopted by the Fund's Board of Trustees, Pioneer may
determine that an unrated security is of equivalent  quality to a rated first or
second tier security.

DIVERSIFICATION.  As a money  market  fund,  the  Portfolio  is  subject  to the
following  special  diversification  requirements.  The Portfolio may not invest
more than 5% of its total assets in securities issued by or subject to puts from
any one issuer (except U.S.  Government  Securities  and  repurchase  agreements
collateralized  by such securities).  In addition,  the Portfolio may not invest
(1) more than 5% of its total assets in second tier  securities or (2) more than
1% of its total assets or $1 million  (whichever  is greater) in the second tier
securities of a single issuer (other than U.S. Government Securities).

MATURITY  POLICIES.  The Portfolio must limit its investments to securities with
remaining  maturities  of 397 days or less and must  maintain a  dollar-weighted
average maturity of 90 days or less.

III. RISK CONSIDERATIONS

RISKS OF INTERNATIONAL INVESTMENTS

The  information  contained in these  paragraphs is of particular  importance to
International Growth Portfolio and Swiss Franc Bond Portfolio;  however, Capital
Growth,  Balanced  and Real  Estate  Growth  Portfolios  may also make  non-U.S.
investments.   Pioneer   limits  the  amount  of  Capital  Growth  and  Balanced
Portfolio's  net assets  that may be invested  in  non-U.S.  securities  to 25%.
Pioneer limits the amount of Real Estate Growth  Portfolio's net assets that may
be invested in non-U.S.  securities to 5%.  Investing  outside the United States
involves  different  opportunities  and different  risks from U.S.  investments.
Pioneer  believes that it may be possible to obtain  significant  returns from a
portfolio of non-U.S.  investments, or a combination of non-U.S. investments and
U.S.  investments,  and to achieve increased  diversification in comparison to a
portfolio  invested  solely  in  U.S.  securities.  By  including  international
investments in your investment portfolio, you may gain increased diversification
by combining  securities from various  countries and geographic areas that offer
different  investment  opportunities  and are  affected  by  different 

<PAGE>

economic trends. At the same time, these  opportunities and trends involve risks
that may not be encountered in U.S. investments.

International   investing  in  general  may  involve  greater  risks  than  U.S.
investments.  There is  generally  less  publicly  available  information  about
non-U.S. issuers, and there may be less government regulation and supervision of
non-U.S. stock exchanges,  brokers and listed companies. There may be difficulty
in  enforcing  legal  rights  outside  the  United  States.  Non-U.S.  companies
generally  are  not  subject  to  uniform  accounting,  auditing  and  financial
reporting standards,  practices and requirements  comparable to those that apply
to U.S.  companies.  Security trading practices abroad may offer less protection
to investors such as the Portfolios. Settlement of transactions in some non-U.S.
markets  may be delayed or may be less  frequent  than in the U.S.,  which could
affect the liquidity of a Portfolio's investments. Additionally, in some foreign
countries,  there is the possibility of expropriation or confiscatory  taxation,
limitations  on the  removal  of  securities,  property,  or other  assets  of a
Portfolio,  political or social  instability,  or diplomatic  developments which
could  affect U.S.  investments  in foreign  countries.  Pioneer will take these
factors into consideration in managing each Portfolio's non-U.S.
investments.

International  Growth Portfolio may invest a portion of its assets in developing
countries,  or in countries with new or developing capital markets; for example,
countries  in Eastern  Europe.  The  considerations  noted  above are  generally
intensified for these investments.  These countries may have relatively unstable
governments,  economies based on only a few industries,  and securities  markets
that trade a small number of securities.  Securities of issuers located in these
countries tend to have volatile prices and may offer  significant  potential for
loss as well as gain.

FOREIGN CURRENCIES.  The value of Swiss Franc Bond Portfolio's and International
Growth Portfolio's non-U.S. investments, and the value of dividends and interest
earned by these Portfolios, may be significantly affected by changes in currency
exchange rates. Currency exchange rates may also affect Capital Growth, Balanced
and Real Estate Growth  Portfolios to the extent that these Portfolios invest in
non-U.S.  securities. Some foreign currency values may be volatile, and there is
the  possibility of governmental  controls on currency  exchange or governmental
intervention in currency  markets,  which could adversely affect the Portfolios.
Pioneer may attempt to manage  currency  exchange rate risks for the  Portfolios
(other than Swiss Franc Bond  Portfolio).  However,  there is no assurance  that
Pioneer  will  do so at an  appropriate  time or  that  Pioneer  will be able to
predict  exchange  rates  accurately.  For  example,  to the extent that Pioneer
increases a  Portfolio's  exposure to a foreign  currency,  and that  currency's
value subsequently falls,  Pioneer's currency management may result in increased
losses to the Portfolio.  Similarly, if Pioneer hedges a Portfolio's exposure to
a foreign currency,  and the currency's value rises, the Portfolio will lose the
opportunity to participate in the currency's appreciation.

Because Swiss Franc Bond Portfolio  seeks to approximate  the performance of the
Swiss franc  relative to the U.S.  dollar,  the Portfolio  will be  particularly
susceptible to the effects of social,  political and economic events that affect
Switzerland  and the  value of the  Swiss  franc  relative  to the U.S.  dollar.
Pioneer will not actively manage the currency exchange rate risk associated with
the Portfolio's  investments.  For  information  about the Swiss economy and the
Swiss franc, see the APPENDIX.

CURRENCY  MANAGEMENT.  The relative  performance of foreign currencies can be an
important  factor in the performance of Swiss Franc Bond  Portfolio,  and in the
performance  of  International  Growth  Portfolio,  each of  which  invests  the
predominant  portion of its assets outside the United States. The performance of
Capital Growth,  Balanced and Real Estate Growth Portfolios may also be affected
by the  relative  performance  of foreign  currencies,  but to a lesser  extent.
Pioneer may manage International Growth,  Capital Growth, Real Estate Growth and
Balanced  Portfolios'  exposure  to  various  currencies  to take  advantage  of
different yield, risk, and return  characteristics that different currencies can
provide for U.S. investors.

To manage  exposure  to currency  fluctuations,  International  Growth,  Capital
Growth and Balanced  Portfolios may enter into forward foreign currency exchange
contracts (agreements to exchange one currency for another at a future date) and
buy and sell options and futures contracts relating to foreign  currencies.  The
Portfolios will use forward foreign  currency  exchange  contracts in the normal
course of business to lock in an exchange rate in connection  with purchases and
sales of securities denominated in foreign currencies. Other currency management
strategies  allow  the  Portfolios  to  hedge  portfolio  securities,  to  shift
investment  exposure from one currency to another,  or to attempt

<PAGE>

to profit from anticipated  declines in the value of a foreign currency relative
to the U.S.  dollar.  Subject to compliance with tax  requirements,  there is no
overall limitation on the amount of International Growth Portfolio's assets that
may be committed to currency management strategies.  Capital Growth and Balanced
Portfolio may engage in currency  management  strategies only to the extent that
they invest in non-U.S.  securities.  Because Real Estate  Growth  Portfolio may
only  invest up to 5% of its net  assets  in  non-U.S.  securities,  it does not
actively seek to manage exposure to currency fluctuations.

Swiss Franc Bond  Portfolio  may enter into forward  foreign  currency  exchange
contracts  to  purchase  Swiss  francs in  connection  with its  investments  in
non-Swiss franc  securities.  The Portfolio may engage in this practice in order
to link an  investment in a non-Swiss  franc  security to the value of the Swiss
franc.  The  Portfolio's use of this strategy will be subject to compliance with
tax requirements.

RISKS OF MEDIUM AND LOWER RATED DEBT SECURITIES

All the Portfolios  except America Income and Money Market Portfolios may invest
in medium rated debt securities  which are usually  defined as securities  rated
"BBB" by S&P or "Baa" by Moody's.  Medium rated debt securities have speculative
characteristics  and  involve  greater  risk  of loss  than  higher  rated  debt
securities,  and are more sensitive to changes in the issuer's  capacity to make
interest payments and repay principal.  Medium rated debt securities represent a
somewhat more  aggressive  approach to income  investing  than higher rated debt
securities.  If the rating of a debt security is reduced below  investment grade
(I.E.,  below  "BBB" by or "Baa"),  Pioneer  will  consider  whatever  action is
appropriate, consistent with the Portfolio's investment objective and policies.

Real Estate Growth and Equity-Income Portfolios may invest up to 5% of their net
assets in lower rated debt securities. International Growth and Swiss Franc Bond
Portfolios may not purchase lower rated debt  securities,  but up to 5% of their
net assets may be  invested  in such  securities  as a result of credit  quality
downgrades.  Lower rated debt securities are usually defined as securities rated
below  "BBB"  by S&P or "Baa"  by  Moody's.  Investments  in  lower  rated  debt
securities  are  speculative  and  changes  in  economic   conditions  or  other
circumstances  are more  likely to lead to a weakened  capacity of the issuer to
make principal and interest payments on such securities.

The  considerations  discussed  above for medium and lower rated debt securities
also apply to medium and lower quality,  unrated debt  instruments of all types.
Unrated debt instruments are not necessarily of lower quality than similar rated
instruments,  but they may not be attractive to as many buyers.  Each  Portfolio
relies more on Pioneer's  credit analysis when investing in debt securities that
are unrated.

Please refer to the  Statement of  Additional  Information  for a discussion  of
Moody's and S&P's ratings.

RISKS ASSOCIATED WITH THE REAL ESTATE INDUSTRY

Real Estate Growth  Portfolio does not invest directly in real estate;  however,
an investment in the Portfolio may be subject to certain risks  associated  with
the  direct  ownership  of real  estate  and with the real  estate  industry  in
general.  These risks include,  among others:  possible declines in the value of
real estate;  risks related to general and local economic  conditions;  possible
lack of  availability  of mortgage funds;  overbuilding;  extended  vacancies of
properties;  increases in  competition,  property taxes and operating  expenses;
changes in zoning laws;  costs  resulting from the clean-up of, and liability to
third parties for damages resulting from,  environmental  problems;  casualty or
condemnation  losses;  uninsured  damages  from  floods,  earth-quakes  or other
natural  disasters;  limitations  on and  variations  in rents;  and  changes in
interest rates.

In addition,  if Real Estate  Growth  Portfolio has rental income or income from
the disposition of real property acquired as a result of a default on securities
the Portfolio owns, the receipt of such income may adversely  affect its ability
to retain its tax status as a regulated  investment company.  See "DISTRIBUTIONS
AND  TAXES" in the  Statement  of  Additional  Information.  Investments  by the
Portfolio  in  securities  of companies  providing  mortgage  servicing  will be
subject to the risks associated with  refinancings and their impact on servicing
rights.
<PAGE>

RISKS ASSOCIATED WITH REAL ESTATE INVESTMENT TRUSTS

Real Estate Growth  Portfolio may invest without  limitation in shares of REITs.
REITs are pooled investment  vehicles which invest primarily in income-producing
real estate or real  estate  related  loans or  interests.  REITs are  generally
classified  as equity  REITs,  mortgage  REITs or a  combination  of equity  and
mortgage  REITs.  Equity REITs  invest the majority of their assets  directly in
real property and derive income  primarily from the collection of rents.  Equity
REITs can also realize capital gains by selling properties that have appreciated
in value.  Mortgage  REITs  invest the  majority of their  assets in real estate
mortgages  and derive  income from the  collection  of interest  payments.  Like
investment  companies such as Real Estate Growth Portfolio,  REITs are not taxed
on  income  distributed  to  shareholders  provided  they  comply  with  several
requirements  of the Internal  Revenue Code of 1986, as amended (the Code).  The
Portfolio will indirectly bear its  proportionate  share of any expenses paid by
REITs in which it invests in addition to the expenses paid by the Portfolio.

Investing  in REITs  involves  certain  unique  risks in addition to those risks
associated with investing in the real estate  industry in general.  Equity REITs
may be affected by changes in the value of the underlying  property owned by the
REITs,  while  mortgage  REITs may be  affected  by the  quality  of any  credit
extended.  REITs are dependent upon management  skills,  are not diversified and
are subject to the risks of financing projects.  REITs are subject to heavy cash
flow dependency, default by borrowers,  self-liquidation,  and the possibilities
of failing to qualify for the exemption  from tax for  distributed  income under
the Code and  failing to maintain  their  exemptions  under the 1940 Act.  REITs
whose  underlying  assets  include  long-term  health care  properties,  such as
nursing,  retirement  and  assisted  living  homes,  may be  affected by federal
regulations concerning the health care industry.

REITs (especially  mortgage REITs) are also subject to interest rate risks. When
interest  rates  decline,  the  value  of a  REIT's  investment  in  fixed  rate
obligations can be expected to rise.  Conversely,  when interest rates rise, the
value of a REIT's  investment  in fixed  rate  obligations  can be  expected  to
decline.

Investing in REITs involves risks similar to those  associated with investing in
small capitalization companies.  REITs may have limited financial resources, may
trade less  frequently and in a limited volume and may be subject to more abrupt
or erratic price movements than larger company securities.  Historically,  small
capitalization  stocks, such as REITs, have been more volatile in price than the
larger capitalization stocks included in the S&P 500 Index.

RISKS ASSOCIATED WITH MORTGAGE-BACKED SECURITIES

Real  Estate  Growth,  Balanced  and  America  Income  Portfolios  may invest in
mortgage-backed  securities.  Mortgage-backed  securities  are  securities  that
directly or indirectly represent  participation in, or are collateralized by and
payable from, mortgage loans secured by real property.  America Income Portfolio
may  invest  in  mortgage-backed  securities  issued or  guaranteed  by the U.S.
Government and its agencies and instrumentalities, including CMOs collateralized
by GNMA,  Fannie Mae or Freddie Mac  certificates.  Real Estate Growth Portfolio
may invest in a variety of mortgage-backed securities and Balanced Portfolio may
invest in GNMA Certificates and CMOs. Refer to the APPENDIX for a description of
these securities.

Investing  in  mortgage-backed  securities  involves  certain  unique  risks  in
addition to those risks associated with investing in the real estate industry in
general.  These  risks  include  the  failure  of a  counter-party  to meet  its
commitments,  adverse  interest rate changes and the effects of  prepayments  on
mortgage cash flows. When interest rates decline,  the value of an investment in
fixed rate obligations can be expected to rise. Conversely,  when interest rates
rise,  the value of an investment in fixed rate  obligations  can be expected to
decline.  In contrast,  as interest rates on adjustable  rate mortgage loans are
reset  periodically,  yields on investments  in such loans will gradually  align
themselves to reflect  changes in market  interest  rates,  causing the value of
such  investments  to fluctuate less  dramatically  in response to interest rate
fluctuations than would investments in fixed rate obligations.

The yield  characteristics  of  mortgage-backed  securities differ from those of
traditional fixed income  securities.  The major  differences  typically include
more  frequent   interest  and  principal   payments  (usually   monthly),   the
adjustability  of  interest  rates,  and the  possibility  that  prepayments  of
principal may be made substantially earlier than their final distribution dates.
<PAGE>

Prepayment  rates are  influenced  by changes in  current  interest  rates and a
variety  of  economic,  geographic,  social  and  other  factors  and  cannot be
predicted with  certainty.  Both  adjustable  rate mortgage loans and fixed rate
mortgage  loans may be subject to a greater rate of principal  prepayments  in a
declining   interest  rate  environment  and  to  a  lesser  rate  of  principal
prepayments in an increasing  interest rate environment.  Under certain interest
rate and  prepayment  rate  scenarios,  Real Estate Growth  Portfolio,  Balanced
Portfolio  and  America  Income   Portfolio  may  fail  to  recoup  fully  their
investments in mortgage-backed securities notwithstanding any direct or indirect
governmental  or  agency   guarantee.   When  a  Portfolio   reinvests   amounts
representing payments and unscheduled prepayments of principal, it may receive a
rate of  interest  that is  lower  than  the rate on  existing  adjustable  rate
mortgage  pass-through  securities.   Thus,   mortgage-backed   securities,  and
adjustable  rate mortgage  pass-through  securities in  particular,  may be less
effective than other types of U.S. Government  Securities as a means of "locking
in" interest rates.

IV. THE FUND AND THE PIONEER ORGANIZATION

The Fund is an open-end,  management  investment company organized as a Delaware
business  trust on September  16, 1994.  The Fund has its own Board of Trustees,
which  supervises  its  activities  and reviews  contractual  arrangements  with
companies that provide each Portfolio with services. The Fund is not required to
hold annual shareholder meetings,  although special meetings may be called for a
specific  Portfolio,  or the Fund as a whole,  for purposes  such as electing or
removing  Trustees,  changing  fundamental  policies or  approving a  management
contract.  An insurance company issuing a Variable Contract that participates in
the Fund will vote  shares of the  Portfolios  held by the  insurance  company's
separate  accounts  as  required  by law.  In  accordance  with  current law and
interpretations  thereof,  participating  insurance  companies  are  required to
request  voting  instructions  from  policyowners  and must  vote  shares of the
Portfolios  in  proportion to the voting  instructions  received.  For a further
discussion of voting rights,  please refer to your insurance  company's separate
account prospectus.


The Pioneer Group,  Inc. (PGI),  established in 1928, is one of America's oldest
investment  managers and has its principal  business address at 60 State Street,
Boston,  Massachusetts.  PGI is the parent  company  of Pioneer  and a number of
different  companies  located in the United States and several other  countries.
These  companies  provide a variety of  financial  services  and  products.  PGI

abroad.  Each  Portfolio  employs  various  PGI  companies  to  perform  certain
activities required for its operation.


John F. Cogan, Jr., Chairman and President of the Fund, President and a Director
of PGI and Chairman and a Director of Pioneer,  owned  approximately  15% of the
outstanding capital stock of PGI as of the date of this Prospectus.


THE MANAGER


Pioneer, the investment adviser to each Portfolio,  provides investment research
and portfolio  management  services to a number of other retail mutual funds and
certain  institutional  clients. It maintains a staff of experienced  investment
personnel and a full  complement of related support  facilities.  As of December
31, 1995,  Pioneer  advised mutual funds with a total value of over $14 billion,
which  includes  more  than  1,000,000  U.S.  shareholder  accounts,  and  other
institutional  accounts.  Pioneer  Funds  Distributor,   Inc.  (PFD),  with  its
principal   business  address  at  60  State  Street,   Boston,   Massachusetts,
distributes  shares of the  Portfolios  and shares of  Pioneer's  retail  mutual
funds.



Each  Portfolio  is overseen by an Equity  Investment  Committee or Fixed Income
Investment   Committee.   Both  Committees  consist  of  Pioneer's  most  senior
investment  professionals  and  are  chaired  by  David  D.  Tripple,  Pioneer's
President and Chief Investment  Officer.  Mr. Tripple joined Pioneer in 1974 and
has had general  responsibility for Pioneer's investment operations and specific
portfolio assignments for more than five years. Fixed income investments made by
Pioneer  are under the  general  supervision  of Sherman B.  Russ,  Senior  Vice
President of Pioneer. Mr. Russ joined Pioneer in 1983.

THE REAL ESTATE GROWTH PORTFOLIO SUBADVISER.  Boston Financial Securities,  Inc.
(BFS),  the investment  subadviser to Real Estate Growth  Portfolio since May 1,
1996,  is an affiliate of the Boston  Financial  Group  Limited  Partnership,  a
Massachusetts  limited partnership ("Boston  Financial"),  which together with a
predecessor  business has   extensive   experience  and  expertise  in  placing,
evaluating and providing advice on a variety of real estate related  investments
since 1969 for individuals,  institutions and real estate professionals. Several
other  affiliates  of BFS also provide a variety of  financial,  consulting  and
management  services to real estate asset managers in the U.S., Boston Financial
oversees investment in over $5.5 billion of properties in 49 states. The company
serves over 37,000 investors with equity contributions in excess of $1.7 billion
in real estate investments.


In its capacity as subadviser to the Portfolio,  BFS (i) identifies and analyzes
real estate  industry  companies,  including  real estate  properties  and other
permissible  investments  for the  Portfolio,  (ii) analyzes  market  conditions
affecting  the real estate  industry  generally  and specific  geographical  and
securities  markets  in which the  Portfolio  may invest or is  invested,  (iii)
continuously  reviews and analyzes  the  investments  in the Real Estate  Growth
Portfolio's portfolio and (iv) furnishes advisory reports based on such analysis
to Pioneer.


Mr.  Fred N. Pratt,  Jr. has the  ultimate  responsibility  for  overseeing  the
provisions  of  subadvisory  services to the Real Estate Growth  Portfolio.  Mr.
Pratt is President and Chief Executive officer of Boston  Financial,  a Director
of BFS and a Trustee of the Real Estate Growth  Portfolio.  Mr. Pratt has worked
in the real estate  industry since 1969.  Mr. David Carter,  a Vice President of
BFS,  has  been  primarily   responsibility  for  the  day-to-day  provision  of
subadvisory  services to the Real Estate Growth  Portfolio  since March 6, 1996.
Mr. Carter has worked as a real estate analyst since 1992.


The  executive   office  of  BFS  are  located  at  101  Arch  Street,   Boston,
Massachusetts  02110. BFS has not previously served as an investment  adviser or
subadviser to a registered  investment company;  however, on March 5, 1996, at a
Special Meeting of Shareholders,  BFS was approved as the investment  subadviser
to Pioneer Real Estate Growth Shares.

Each  Portfolio,  other than Balanced  Portfolio and Swiss Franc Bond Portfolio,
has an investment objective and policies similar to those of an existing Pioneer
retail mutual fund.  International  Growth  Portfolio is most similar to Pioneer
International  Growth Fund,  Capital Growth  Portfolio to Pioneer Capital Growth
Fund, Real Estate Growth Portfolio to Pioneer Real Estate Shares,  Equity-Income
Portfolio to Pioneer  Equity-Income  Fund,  America Income  Portfolio to Pioneer
America  Income Trust and Money Market  Portfolio to Pioneer Cash Reserves Fund.
Performance  of  these  Portfolios  is  not  expected  to be  the  same  as  the
performance   of  the   corresponding   retail   mutual

<PAGE>

fund due in part to  dissimilarities  in their  investments.  Various  insurance
costs will also affect the  performance  of investments  in the  Portfolios,  as
measured for the Accumulation Units of your Variable Contract.


PORTFOLIO TRANSACTIONS

Orders for each Portfolio's securities transactions are placed by Pioneer, 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 investment research or brokerage services or sells shares
of a  Portfolio  or other  funds for which  Pioneer or any  affiliate  serves as
investment adviser or manager. See the STATEMENT OF ADDITIONAL INFORMATION for a
further description of Pioneer's brokerage allocation practices.

 Each of the Portfolios is substantially  fully invested at all times. It is the
policy of the  Portfolios  not to  engage in  trading  for  short-term  profits,
although a Portfolio  may do so when it believes a particular  transaction  will
contribute to the achievement of its investment objective. Nevertheless, changes
in any Portfolio will be made promptly when determined to be advisable by reason
of developments not foreseen at the time of the initial investment decision, and
usually  without  reference  to the  length of time a  security  has been  held.
Accordingly,  portfolio turnover rate is not considered a limiting factor in the
execution of investment decisions.


The frequency of portfolio  transactions-a  Portfolio's  turnover rate-will vary
from year to year depending on market  conditions.  Portfolio turnover rates are
not generally expected to exceed 100% with the exception of International Growth
Portfolio's  turnover  rate,  which  may be as  high  as  300%.  See  "Financial
Highlights" for actual turnover rates.  Because a higher turnover rate increases
transaction  costs and may have  certain  tax  consequences,  Pioneer  carefully
weighs the anticipated benefits of short-term investment against these factors.


V. FUND MANAGEMENT FEES AND OTHER EXPENSES

Each Portfolio pays a management fee to Pioneer for managing its investments and
business  affairs.  Each  Portfolio's  management fee is computed daily and paid
monthly at the following annual rate:

                                               MANAGEMENT FEE AS A PERCENTAGE
                                                OF PORTFOLIO'S AVERAGE DAILY
PORTFOLIO                                               NET ASSETS
International Growth Portfolio 1                          1.00%
Capital Growth Portfolio                                  0.65%
Real Estate Growth Portfolio 1                            1.00%
Equity-Income Portfolio                                   0.65%
Balanced Portfolio                                        0.65%
Swiss Franc Bond Portfolio                                0.65%
America Income Portfolio                                  0.55%
Money Market Portfolio                                    0.50%
- ------------------------
(1) International and real estate investing involves greater complexity, expense
and  commitment of resources than ordinary  equity  investing and the management
fees for International  Growth and Real Estate Growth Portfolios are higher as a
result,  although  not  necessarily  higher than those of other funds  investing
primarily in similar types of securities.



During the fiscal period ended December,  1995, the Portflios  incurred expenses
as follows: International Growth, $145,854; Capital Growth,$108,885; Real Estate
Growth, $86,959;  Equity-Income,  $90,061; Balanced,  $90,240; Swiss Franc Bond,
$13,723;  America  Income,  $83,708;and  Money  Market,  $83,754.  Such expenses
included  management  fees paid or payable to Pioneer as follows:  International
Growth,   $8,341;   Capital   Growth,$17,739;   Real  Estate   Growth,   $1,879;
Equity-Income,  $10,878;  Balanced,  $3,924;  Swiss  Franc Bond,  $127;  America
Income,


<PAGE>

$3,861;and  Money  Market,  $4,972.  Pursuant  to  Pioneer's  voluntary  expense
limitation  agreements,  Pioneer did not impose its management fee on any of the
Portfolios.


Pioneer  has  agreed not to impose a portion  of its  management  fee or to make
other  arrangements to reduce  Portfolio  expenses to a specified  percentage of
average daily net assets,  as indicated  below.  Such agreements or arrangements
may be terminated by Pioneer at any time without notice

                                             PERCENTAGE OF PORTFOLIO'S

PORTFOLIO                                     AVERAGE DAILY NET ASSETS
  International Growth Portfolio                      1.50%
  Capital Growth Portfolio                            1.25%
  Real Estate Growth Portfolio                        1.25%
  Equity-Income Portfolio                             1.25%
  Balanced Portfolio                                  1.25%
  Swiss Franc Bond Portfolio                          1.25%
  America Income Portfolio                            1.25%
  Money Market Portfolio                              1.00%


Under the terms of their respective  management contracts with the Fund, Pioneer
assists in the  management of each Portfolio and is authorized in its discretion
to buy and sell securities for the account of each  Portfolio.  Pioneer pays all
the  expenses,  including  executive  salaries and the rental of certain  office
space,  related to its services for each  Portfolio,  with the  exception of the
following  which are paid by each  Portfolio:  (a) charges and expenses for fund
accounting,  pricing and appraisal services and related overhead,  including, to
the  extent  such  services  are  performed  by  personnel  of  Pioneer  or  its
affiliates, office space and facilities and personnel compensation, training and
benefits; (b) the charges and expenses of auditors; (c) the charges and expenses
of any custodian,  transfer agent,  plan agent,  dividend  disbursing  agent and
registrar  appointed  by the Fund with respect to the  Portfolio;  (d) issue and
transfer  taxes,  chargeable  to the  Portfolio in  connection  with  securities
transactions to which the Portfolio is a party; (e) insurance premiums, interest
charges,  dues and fees for membership in trade associations,  and all taxes and
corporate fees payable by the Portfolio to federal,  state or other governmental
agencies;  (f)  fees  and  expenses  involved  in  registering  and  maintaining
registrations of the Fund and/or its shares with the SEC,  individual  states or
blue sky securities agencies,  territories and foreign countries,  including the
preparation of Prospectuses and Statements of Additional  Information for filing
with the SEC; (g) all expenses of  shareholders'  and Trustees'  meetings and of
preparing, printing and distributing prospectuses, notices, proxy statements and
all  reports to  shareholders  and to  governmental  agencies;  (h)  charges and
expenses of legal  counsel to the Fund and the  Trustees;  (i)  compensation  of
those Trustees of the Trust who are not affiliated with or interested persons of
Pioneer,  the  Fund  (other  than  as  Trustees),  PGI or PFD;  (j) the  cost of
preparing and printing share  certificates;  and (k) interest on borrowed money,
if any. In addition to the expenses  described  above,  each Portfolio shall pay
all  brokers'  and  underwriting  commissions  chargeable  to the  Portfolio  in
connection with securities transactions to which the Portfolio is a party.


SUBADVISORY  FEE FOR REAL  ESTATE  GROWTH  PORTFOLIO.  As  compensation  for its
subadvisory services,  Pioneer will pay BFS a subadvisory fee equal to 0.30% per
annum of the Real  Estate  Growth  Portfolio's  average  daily net  assets.  The
subadvisory fee payable by Pioneer to BFS could be reduced proportionally to the
extent that the  management  fee paid by the Real  Estate  Growth  Portfolio  to
Pioneer is reduced under Pioneer's  voluntary expense  limitation  agreement or,
after  written  notice to BFS,  to the extent that  Pioneer  elects to utilize a
portion  of the  management  fees  paid to  Pioneer  by the Real  Estate  Growth
Portfolio to make payments to third parties. No fees were paid by Pioneer to BFS
during fiscal 1995.


VI. PERFORMANCE

Each Portfolio's  performance may be quoted in advertising in terms of yield and
total return if accompanied by performance for your insurance company's separate
account.  Performance  is based on  historical  results  and is not  intended to
indicate future performance.  For additional  performance  information,  contact
your insurance company for a free annual report.
<PAGE>

For  America  Income  Portfolio,  Swiss  Franc  Bond  Portfolio,   Equity-Income
Portfolio and Balanced  Portfolio,  yield is a way of showing the rate of income
the Portfolio earns on its investments as a percentage of the Portfolio's  share
price. To calculate  yield, a Portfolio takes the dividend and interest  income,
if any, it earned  from its  portfolio  of  investments  for a specified  30-day
period  (net of  expenses),  divides it by the number of its shares  entitled to
receive  dividends and expresses  the result as an  annualized  percentage  rate
based on the Portfolio's share price at the end of the 30-day period.

Money Market  Portfolio's  yield refers to the income generated by an investment
in the  Portfolio  over a specified  seven-day  period,  expressed  as an annual
percentage rate. The Portfolio's  EFFECTIVE YIELD is calculated  similarly,  but
assumes that the income earned from  investments  is reinvested in shares of the
Portfolio.  Money Market  Portfolio's  effective  yield will tend to be slightly
higher than its yield because of the compounding effect of this reinvestment.

Yields are calculated  according to accounting methods that are standardized for
all stock and bond  funds.  Because  yield  accounting  methods  differ from the
methods used for other accounting  purposes,  a Portfolio's  yield may not equal
its  distribution  rate, the income paid to an account or the income reported on
the Portfolio's financial statements.

A Portfolio's  total return is based on the overall dollar or percentage  change
in value of a  hypothetical  investment in the Portfolio,  including  changes in
share price (except for Money Market  Portfolio)  and assuming each  Portfolio's
dividends and capital gain  distributions  are  reinvested at net asset value. A
cumulative total return reflects a Portfolio's  performance over a stated period
of time.  An average  annual total return  reflects  the  hypothetical  annually
compounded return that would have produced the same cumulative total return if a
Portfolio's  performance  had been  constant  over the  entire  period.  Because
average  annual  returns tend to smooth out  variations in a Portfolio's  actual
return,  you should recognize that they are not the same as actual  year-by-year
results.  To illustrate the components of overall  performance,  a Portfolio may
separate its  cumulative  and average  annual  returns  into income  results and
capital gain or loss.


YIELDS  AND TOTAL  RETURNS  QUOTED  FOR THE  PORTFOLIOS  INCLUDE  THE  EFFECT OF
DEDUCTING EACH  PORTFOLIO'S  EXPENSES,  BUT MAY NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR INSURANCE PRODUCT. SINCE SHARES OF THE PORTFOLIOS
MAY BE  PURCHASED  PRIMARILY  THROUGH A VARIABLE  CONTRACT,  PURCHASERS  OF SUCH
CONTRACTS  SHOULD  CAREFULLY  REVIEW THE  PROSPECTUS  OF THE SELECTED  INSURANCE
PRODUCT FOR  INFORMATION  ON  RELEVANT  CHARGES AND  EXPENSES.  Excluding  these
charges  from  quotations  of each  Portfolio's  performance  has the  effect of
increasing the performance  quoted.  You should bear in mind the effect of these
charges when comparing a Portfolio's performance to that of other mutual funds.


VII. DISTRIBUTIONS AND TAXES



For a discussion  of the tax status of a Variable  Contract,  including  the tax
consequences  of withdrawals or other  payments,  refer to the prospectus of the
Variable Contract insurance company's separate account. It is suggested you keep
all  statements  you receive to assist in your personal  record  keeping.  It is
expected that shares of the Portfolios  will be held primarily by life insurance
company separate accounts that fund Variable Contracts.  A Portfolio's dividends
and capital gain  distributions  are  generally  treated as ordinary  income and
long-term capital gain, respectively, under the Code. Insurance companies should
consult  their own tax  advisers  regarding  the tax  treatment  of dividends or
capital gain distributions they receive from any Portfolio.


Each  Portfolio is treated as a separate  entity for federal income tax purposes
and has  elected or intends  to elect to be  treated as a  regulated  investment
company  under  Subchapter M of the Code and to qualify for such  treatment  for
each taxable  year.  To qualify as such,  each  Portfolio  must satisfy  certain
requirements  relating  to the  sources of its  income,  diversification  of its
assets and distribution of its income to shareholders. As a regulated investment
company,  each  Portfolio  will not be subject to federal  income tax on any net
investment  income and net realized  capital gains that are  distributed  to its
shareholders in accordance with certain timing requirements of the Code.

<PAGE>

Each  Portfolio  intends  to pay out all of its net  investment  income  and net
realized capital gains for each year.  International Growth,  Capital Growth and
Swiss Franc Bond Portfolios distribute their dividends,  if any, each year. Real
Estate Growth, Equity-Income and Balanced Portfolios distribute their dividends,
if any, quarterly. Dividends from America Income and Money Market Portfolios are
declared daily and paid monthly.  Normally,  net realized capital gains, if any,
are distributed each year for the Portfolios.  Such income and capital gains are
automatically reinvested in additional shares of the Portfolios.

All  Portfolios  make  dividend  and capital gain  distributions  on a per-share
basis.  After  every  distribution  from each  Portfolio,  except  Money  Market
Portfolio and America Income Portfolio's dividend distributions from income, the
Portfolio's  share price drops by the amount of the  distribution as a result of
the distribution. Since dividends and capital gain distributions are reinvested,
the  total  value of an  account  will  not be  affected  by such  distributions
because,   although  the  shares  will  have  a  lower  price,   there  will  be
correspondingly more of them.


In  addition  to the  above,  each  Portfolio  also  follows  certain  portfolio
diversification  requirements  imposed  by  the  IRS  on  separate  accounts  of
insurance  companies relating to the tax-deferred  status of Variable Contracts.
These requirements,  which are in addition to the  diversification  requirements
imposed on the Portfolios by the 1940 Act (only Real Estate Growth  Portfolio is
exempt from the 1940 Act's diversification requirements) and Subchapter M of the
Code  generally,  subject to a safe harbor or other available  exception,  place
certain  percentage  limitations  on  the  assets  of a  Portfolio  that  may be
represented  by  any  one,  two,  three  or  four  investments.   More  specific
information on these diversification  requirements is contained in the insurance
company's  separate account prospectus and in the Fund's Statement of Additional
Information.


VIII. SHAREHOLDER INFORMATION

OPENING AN ACCOUNT



SINCE INDIVIDUAL  INVESTORS MAY NOT PURCHASE  PORTFOLIO  SHARES  DIRECTLY,  THEY
SHOULD READ THE PROSPECTUS OF THE INSURANCE COMPANY'S SEPARATE ACCOUNT TO OBTAIN
INSTRUCTIONS  FOR  PURCHASING  A VARIABLE  ANNUITY OR  VARIABLE  LIFE  INSURANCE
CONTRACT AND INFORMATION ON THE ALLOCATION OF RETIREMENT PLAN PURCHASE  PAYMENTS
AMONG THE PORTFOLIOS.



SHARE PRICE

The term "net asset value" or NAV per share refers to the worth of one share.  A
Portfolio's  NAV per share is  computed  by adding the value of the  Portfolio's
investments,  cash and other  assets,  deducting  liabilities  and  dividing the
result by the number of shares outstanding.  Each Portfolio is open for business
each day the New York Stock  Exchange (the NYSE) is open. The price of one share
of a Portfolio is its NAV which is normally  calculated daily as of the close of
business of the NYSE (normally 4:00 p.m., Eastern time).

The investments of each Portfolio (other than Money Market Portfolio) 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.  The securities of each Portfolio  (other than
Money Market Portfolio) are valued primarily on the basis of market quotations.


Securities quoted in foreign  currencies are converted to U.S. dollars utilizing
foreign exchange rates employed by the Portfolios' independent pricing services.
Generally,  trading in foreign securities is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the NAV of the Portfolios'  shares are determined as of such times.
Foreign currency exchange rates are also generally determined prior to the close
of the NYSE. 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 the NYSE and will therefore not be reflected in the  computation of
a Portfolio's NAV. 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.

<PAGE>

Money Market Portfolio's  investments are valued on the basis of amortized cost.
This means of valuation assumes a steady rate of amortization of any premium and
discount from the date of purchase until maturity.

For all  Portfolios,  investments  for which market  quotations  are not readily
available  will  be  valued  by a  method  which  the  Fund's  Trustees  believe
accurately reflects fair value.

INVESTMENTS IN SHARES OF THE PORTFOLIOS

Each Portfolio may sell its shares directly to separate accounts established and
maintained by insurance  companies for the purpose of funding Variable Contracts
and to certain qualified pension and retirement plans (Qualified Plans).  Shares
offered to Qualified Plans will be offered by a separate  prospectus.  Shares of
the  Portfolios  are  sold  at  NAV.  Variable  Contracts  may or may  not  make
investments in all the Portfolios  described in this Prospectus.  Investments in
each Portfolio are expressed in terms of the full and  fractional  shares of the
Portfolio  purchased.  Investments  in a Portfolio  are credited to an insurance
company's separate account  immediately upon acceptance of the investment by the
Portfolio.  Investments  will be processed at the next NAV  calculated  after an
order is received  and  accepted by a  Portfolio.  The offering of shares of any
Portfolio may be suspended for a period of time and each Portfolio  reserves the
right to reject any specific purchase order.  Purchase orders may be refused if,
in Pioneer's opinion,  they are of a size that would disrupt the management of a
Portfolio.

The Fund currently does not foresee any  disadvantages to investors  arising out
of the fact  that each  Portfolio  may offer  its  shares to  insurance  company
separate  accounts  that  serve as the  investment  medium  for  their  Variable
Contracts  or that  each  Portfolio  may offer its  shares to  Qualified  Plans.
Nevertheless, the Fund's Board of Trustees intends to monitor events in order to
identify any material irreconcilable  conflicts which may possibly arise, and to
determine what action, if any, should be taken in response to such conflicts. If
such a  conflict  were to  occur,  one or  more  insurance  companies'  separate
accounts or Qualified  Plans might be required to withdraw their  investments in
one or more Portfolios and shares of another Portfolio may be substituted.  This
might  force a  Portfolio  to sell  securities  at  disadvantageous  prices.  In
addition,  the Board of Trustees  may refuse to sell shares of any  Portfolio to
any separate  account or Qualified Plan or may suspend or terminate the offering
of shares of any  Portfolio  if such  action is  required  by law or  regulatory
authority or is in the best interests of the shareholders of the Portfolio.

REDEMPTIONS

Shares of a Portfolio  may be  redeemed on any  business  day.  Redemptions  are
effected at the per share NAV next  determined  after receipt and  acceptance of
the  redemption  request by a Portfolio.  Redemption  proceeds  will normally be
forwarded by bank wire to the redeeming  insurance  company on the next business
day after receipt of the redemption  instructions by a Portfolio but in no event
later than 7 days following receipt of instructions.  Each Portfolio may suspend
redemptions  or  postpone  payment  dates  during any period in which any of the
following  conditions  exists:  the NYSE is  closed  or  trading  on the NYSE is
restricted;  an emergency  exists as a result of which disposal by the Portfolio
of securities owned by it is not reasonably  practicable or it is not reasonably
practicable  for the Portfolio to fairly  determine the value of its net assets;
or the SEC, by order, so permits.

Please refer to the prospectus of your insurance  company's separate account for
information on how to redeem from each Portfolio.

IX. APPENDIX

The following  paragraphs  provide a brief description of certain  securities in
which the Portfolios may invest and certain  investment  practices in which they
may engage.  Unless  stated  otherwise,  each security and  investment  practice
listed  below may be used by each  Portfolio.  No  Portfolio  is limited by this
discussion,  however,  and each Portfolio may purchase other types of securities
and enter into  other  types of  transactions  if they are  consistent  with its
investment objective and policies.

SHORT-TERM  INVESTMENTS.  As described in "INVESTMENT  OBJECTIVES AND POLICIES,"
each  Portfolio  (other than Money Market  Portfolio)  may invest in  short-term

<PAGE>

investments  consisting  of:  corporate  commercial  paper and other  short-term
commercial  obligations,  in each case rated or issued by companies with similar
securities  outstanding that are rated Prime-1,  Aa or better by Moody's or A-1,
AA or  better by S&P;  obligations  (including  certificates  of  deposit,  time
deposits,  demand  deposits and banker's  acceptances)  of banks with securities
outstanding  that are rated  Prime-1,  Aa or better by  Moody's,  or A-1,  AA or
better by S&P;  obligations  issued or guaranteed by the U.S.  Government or its
agencies or instrumentalities with remaining maturities not exceeding 18 months;
and repurchase  agreements.  Normally,  Swiss Franc Bond Portfolio may invest in
similar  short-term  investments  that are  denominated in Swiss francs or other
non-U.S.  currencies,  but  may  invest  in U.S.  dollar-denominated  short-term
securities for certain purposes,  including temporary defensive purposes.  Money
Market  Portfolio's  short-term  investments  are subject to certain  additional
restrictions. See "INVESTMENT OBJECTIVES AND POLICIES."

         BANKERS' ACCEPTANCES are obligations of a bank to pay a draft which has
         been drawn on it by a customer.  These  obligations are backed by large
         banks and usually backed by goods in international trade.

         CERTIFICATES OF DEPOSIT  represent a commercial  bank's  obligations to
         repay funds deposited with it, earning specified rates of interest over
         given periods.

         COMMERCIAL PAPER is a short-term  unsecured  promissory note, including
         variable amount master demand notes,  issued by banks,  broker-dealers,
         corporations  or other  entities for purposes  such as financing  their
         current operations.


REPURCHASE  AGREEMENTS  AND LENDING OF  SECURITIES.  As described IN "INVESTMENT
OBJECTIVES AND POLICIES," each Portfolio may enter into  repurchase  agreements.
In a  repurchase  agreement,  a  Portfolio  buys a  security  at one  price  and
simultaneously agrees to sell it back to the seller at a higher price, generally
for a period not exceeding seven days and fully  collateralized  with investment
grade  debt  securities  with a  market  value  of not  less  than  100%  of the
obligation,  valued daily.  Each  Portfolio  other than America Income and Money
Market  Portfolios  may lend  securities  to  broker-dealers  and  institutional
investors,  provided that the value of securities  loaned by a Portfolio may not
exceed 33 1/3 % of its total assets. In the event of the bankruptcy of the other
party  to a  repurchase  agreement  or a  securities  loan,  a  Portfolio  could
experience  delays in  recovering  its cash or the  securities  it lent.  To the
extent  that,  in the  meantime,  the  value  of the  securities  purchased  had
decreased,  or the value of the  securities  lent had  increased,  the Portfolio
could experience a loss. In all cases, Pioneer must find the creditworthiness of
the other party to the transaction satisfactory.


RESTRICTED  SECURITIES.  Each  Portfolio  (other than  America  Income and Money
Market  Portfolios)  may  invest  up to 5% of  its  net  assets  in  "restricted
securities," (I.E.,  securities that would be required to be registered prior to
distribution to the public), excluding restricted securities eligible for resale
to certain  institutional  investors  pursuant to Rule 144A under the Securities
Act of 1933  and,  for  Portfolios  that  allow  non-U.S.  investments,  foreign
securities which are offered or sold outside the United States.  In no instance,
however, may more than 15% of a Portfolio's net assets be invested in restricted
securities,  including securities eligible for resale under Rule 144A. It is not
possible to predict with  assurance  exactly how the market for such  restricted
securities  will  develop  and  investments  in  restricted  securities  will be
carefully monitored by Pioneer and by the Fund's Trustees.

ILLIQUID  INVESTMENTS.  Each Portfolio may invest up to 15% (except Money Market
Portfolio  which is limited to 10%) of its net  assets in  illiquid  investments
which  includes  securities  that  are not  readily  marketable  and  repurchase
agreements  maturing in more than seven days.  The Fund's  Trustees have adopted
guidelines  and  delegated  to Pioneer  the daily  function of  determining  and
monitoring the liquidity of restricted securities. The Trustees, however, retain
sufficient oversight and are ultimately responsible for the determination. Under
the  supervision of the Board of Trustees,  Pioneer  determines the liquidity of
each  Portfolio's  investments.  The  absence  of a trading  market  can make it
difficult to ascertain a market  value for  illiquid  investments.  Disposing of
illiquid investments may involve time-consuming  negotiation and legal expenses,
and it may be difficult or  impossible  for a Portfolio to sell them promptly at
an acceptable price.

FORWARD CURRENCY EXCHANGE  CONTRACTS.  International  Growth,  Swiss Franc Bond,
Capital Growth,  Real Estate Growth and Balanced Portfolios each has the ability
to hold a portion of its assets in  non-U.S.  currencies  and  purchase  or sell
forward  currency  exchange  contracts  to  facilitate  settlement  of  non-U.S.
securities  transactions  or to

<PAGE>

protect  against  changes in currency  exchange  rates. A Portfolio might sell a
non-U.S.  currency  on  either a spot  (I.E.,  cash) or  forward  basis to hedge
against an anticipated  decline in the U.S.  dollar value of securities  that it
owns or securities  that it intends to sell or to preserve the U.S. dollar value
of dividends, interest or other amounts it expects to receive.  Alternatively, a
Portfolio  might purchase a non-U.S.  currency or enter into a forward  purchase
contract  for the  non-U.S.  currency  to  preserve  the  U.S.  dollar  price of
securities it intends to purchase.  A portfolio may also engage in cross-hedging
by using forward contracts in one currency to hedge against  fluctuations in the
value of securities denominated in a different currency.

Swiss Franc Bond Portfolio may also purchase and sell forward currency  exchange
contracts  for Swiss  francs in order to link the  value of an  investment  in a
non-Swiss   franc  security  to  the  value  of  the  Swiss  franc.   See  "RISK
CONSIDERATIONS--CURRENCY MANAGEMENT."

MORTGAGE-BACKED SECURITIES. Real Estate Growth Portfolio may invest up to 25% of
its total  assets  in  mortgage  pass-through  certificates  and  multiple-class
pass-through  securities,  such as guaranteed mortgage pass-through  securities,
real estate  mortgage  investment  conduit  (REMIC)  pass-through  certificates,
collateralized   mortgage   obligations  (CMOs)  and  stripped   mortgage-backed
securities  (SMBS) and other  types of  mortgage-backed  securities  that may be
available in the future.  America Income Portfolio may invest in mortgage-backed
securities that are issued or guaranteed by the U.S. Government, its agencies or
instrumentalities,   and  in  CMOs.   Balanced  Portfolio  may  invest  in  GNMA
Certificates, which are a type of mortgage pass-through security, and in CMOs.

Mortgage-backed  securities are issued by government and non-government entities
such  as  banks,   mortgage   lenders  or  other   financial   institutions.   A
mortgage-backed security may be an obligation of the issuer backed by a mortgage
or pool of mortgages or a direct  interest in an  underlying  pool of mortgages.
Some mortgage-backed  securities, such as collateralized mortgage obligations or
CMOs,  make  payments of both  principal and interest at a variety of intervals;
others  make  semiannual  interest  payments at a  predetermined  rate and repay
principal at maturity  (like a typical  bond).  Mortgage-backed  securities  are
based on different types of mortgages  including those on commercial real estate
or residential properties. Other types of mortgage-backed securities will likely
be  developed  in the  future,  and a  Portfolio  may  invest in them if Pioneer
determines they are consistent with its investment objective and policies.  Real
Estate  Growth,  Balanced and America Income  Portfolios  will not invest in the
lowest tranche of CMOs or REMIC certificates.

The value of mortgage-backed securities may change due to shifts in the market's
perception  of issuers.  In addition,  regulatory  or tax changes may  adversely
affect the mortgage securities market as a whole. Non-government mortgage-backed
securities may offer higher yields than those issued by government entities, but
also  may  be  subject  to  greater  price  changes  than   government   issues.
Mortgage-backed  securities are subject to prepayment  risk.  Prepayment,  which
occurs when unscheduled or early payments are made on the underlying  mortgages,
may shorten the  effective  maturities of these  securities  and may lower their
total returns.

         GUARANTEED  MORTGAGE  PASS-THROUGH  SECURITIES may be purchased by Real
         Estate Growth, Balanced and America Income Portfolios. These securities
         represent  participation  interests  in pools of  residential  mortgage
         loans and are  issued  by U.S.  Governmental  or  private  lenders  and
         guaranteed   by  the  U.S.   Government  or  one  of  its  agencies  or
         instrumentalities, including but not limited to the Government National
         Mortgage  Association (GNMA), the Federal National Mortgage Association
         (Fannie Mae) and the Federal Home Loan  Mortgage  Corporation  (Freddie
         Mac).

         MULTIPLE-CLASS  PASS-THROUGH  SECURITIES  AND  COLLATERALIZED  MORTGAGE
         OBLIGATIONS.    Real   Estate   Growth   Portfolio's   investments   in
         mortgage-backed  securities may include CMOs and REMIC  pass-through or
         participation certificates,  which may be issued by, among others, U.S.
         Government agencies and  instrumentalities  as well as private lenders.
         Balanced  Portfolio's  investments  in  mortgage-backed  securities may
         include   CMOs.   America   Income   Portfolio   may   invest  in  CMOs
         collateralized by GNMA,  Fannie Mae or Freddie Mac  certificates.  CMOs
         and REMIC certificates are issued in multiple classes and the principal
         of and  interest on the  underlying  mortgage  assets may be  allocated
         among the  several  classes  of CMOs or REMIC  certificates  in various
         ways. Each class of CMOs or REMIC certificates,  often referred to as a
         "tranche," is issued at a specific  adjustable  or fixed  interest rate
         and must be fully  retired no later than its 

<PAGE>

         final distribution date. Generally,  interest is paid or accrues on all
         classes of CMOs or REMIC certificates on a monthly basis.

         Typically,  CMOs are  collateralized by GNMA, Fannie Mae or Freddie Mac
         certificates  but also may be  collateralized  by other mortgage assets
         such as whole loans or private mortgage pass-through  securities.  Debt
         service on CMOs is provided  from payments of principal and interest on
         collateral of mortgaged assets and any reinvestment income thereon.

         REAL  ESTATE  MORTGAGE   INTEREST  CONDUIT  (REMIC)  interests  may  be
         purchased  by Real  Estate  Growth  Portfolio.  A REMIC  is a CMO  that
         qualifies  for  special  tax  treatment  under the Code and  invests in
         certain  mortgages  primarily secured by interests in real property and
         other  permitted  investments.  Investors  may purchase  "regular"  and
         "residual"  interest  shares of  beneficial  interest  in REMIC  trusts
         although the Portfolio does not intend to invest in residual interests.

         STRIPPED MORTGAGE-BACKED SECURITIES are currently intended for use only
         by Real Estate Growth  Portfolio.  Such  securities  are created when a
         U.S.  Government  agency  or  a  financial  institution  separates  the
         interest and  principal  components of a  mortgage-backed  security and
         sells them as individual securities. The holder of the "principal-only"
         security (PO) receives the  principal  payments made by the  underlying
         mortgage-backed  security,  while  the  holder  of the  "interest-only"
         security  (IO)  receives  interest  payments  from the same  underlying
         security.

         The prices of stripped  mortgage-backed  securities may be particularly
         affected  by  changes  in  interest  rates.  As  interest  rates  fall,
         prepayment rates tend to increase,  which tends to reduce prices of IOs
         and increase prices of POs. Rising interest rates can have the opposite
         effect.

OPTIONS AND FUTURES CONTRACTS provide a way for  International  Growth,  Capital
Growth,  Real Estate  Growth and Swiss  Franc Bond  Portfolios  to manage  their
exposure to changing  interest rates,  security  prices,  and currency  exchange
rates. Some options and futures  strategies,  including selling futures,  buying
puts and writing calls,  tend to hedge a Portfolio's  investments  against price
fluctuations.  Other  strategies,  including  buying  futures,  writing puts and
buying  calls,  tend to  increase  market  exposure.  Options and futures may be
combined  with each other or with forward  contracts in order to adjust the risk
and return  characteristics of a Portfolio's  overall strategy.  A Portfolio may
invest in options and futures based on any type of security,  index or currency,
including  options and  futures  traded on  non-U.S.  exchanges  and options not
traded on exchanges.

Subject  to  compliance  with  tax and  other  requirements,  Swiss  Franc  Bond
Portfolio  may  enter  into  options  and  futures  contracts  in  order to gain
investment exposure to the Swiss franc.

Options and futures can be volatile  investments  and involve  certain risks. If
Pioneer  applies a hedge at an  inappropriate  time or judges market  conditions
incorrectly,  options and futures  strategies may lower a Portfolio's  return. A
Portfolio could also experience  losses if the prices of its options and futures
positions were poorly correlated with its other investments,  or if it could not
close out its positions because of an illiquid secondary market.

DEPOSITARY  RECEIPTS.  International  Growth  Portfolio  and, to a lesser extent
Capital  Growth,  Real  Estate  Growth  and  Balanced  Portfolios  may invest in
securities  of  non-U.S.  issuers in the form of  American  Depositary  Receipts
(ADRs),  Global  Depositary  Receipts  (GDRs)  and  other  similar  instruments.
Generally,  ADRs in  registered  form are  designed  for use in U.S.  securities
markets,  and GDRs and other  similar  global  instruments  in  bearer  form are
designed for use in non-U.S.  securities  markets.  ADRs are denominated in U.S.
dollars and represent an interest in the right to receive securities of non-U.S.
issuers deposited in a U.S. bank or a correspondent  bank. ADRs do not eliminate
all the risk  inherent in  investing  in the  securities  of  non-U.S.  issuers.
However,  by  investing  in ADRs rather  than  directly in the stock of non-U.S.
issuers,  a Portfolio will avoid currency risks during the settlement period for
either  purchases or sales.  GDRs are not  necessarily  denominated  in the same
currency as the securities for which they may be exchanged.  For purposes of the
Portfolios'   investment  policies,   investments  in  ADRs,  GDRs  and  similar
instruments will be deemed to be investments in the equity securities into which
they may be converted.
<PAGE>

WARRANTS.   International   Growth,   Capital   Growth,   Real  Estate   Growth,
Equity-Income and Balanced Portfolios may invest in warrants,  which entitle the
holder to buy equity  securities at a specific  price over a specific  period of
time.  Warrants may be considered more  speculative  than certain other types of
investments,  in that they do not  entitle  the  holder to  dividends  or voting
rights  with  respect  to the  securities  which  may be  purchased  nor do they
represent  any  rights in the  assets  of the  issuing  company.  The value of a
warrant  may be  more  volatile  than  the  value  of the  warrant's  underlying
securities.  Also, the value of the warrant does not necessarily change with the
value of the  underlying  securities and a warrant ceases to have value if it is
not exercised prior to the expiration date.



THE SWISS  FRANC AND THE SWISS  ECONOMY.  As of  December  31,  1995,  the Swiss
franc-U.S.  dollar  exchange  rate was  $1.154Sfr  = US$1.  Switzerland's  Gross
Domestic  Product in 1995 was U.S.  $306.1 ($361.9  billion Sfr).  Switzerland's
current  account  surplus  totaled  $23.86 billion Sfr or 6.5% of Gross Domestic
Product in 1995. Inflation in Switzerland averaged 1.8% in 1995.
