PROSPECTUS FEBRUARY 28, 1995
AS SUPPLEMENTED JUNE 1, 1995

     Keystone World Bond Fund (formerly named Keystone  America World Bond Fund)
(the  "Fund")  is a mutual  fund  authorized  to issue  more than one  series of
shares.  At this time, the Fund issues shares of only one  portfolio,  the World
Bond Portfolio (the "Portfolio").

     The   Portfolio   seeks  current   income  by  investing   primarily  in  a
non-diversified  portfolio  consisting of debt securities  denominated in United
States ("U.S.") and foreign currencies. The Portfolio seeks capital appreciation
as a secondary objective.

     Generally,  the Portfolio  offers three classes of shares.  Information  on
share  classes  and their fee and sales  charge  structures  may be found in the
Fund's fee table, "Alternative Sales Options," "Contingent Deferred Sales Charge
and Waiver of Sales Charges," "Distribution Plans," and "Fund Shares."

     This  prospectus  concisely  states  information  about  the  Fund  and the
Portfolio  that you should know before  investing.  Please read it and retain it
for future reference.

     Additional  information  about the Fund and the Portfolio is contained in a
statement of additional  information  dated  February 28, 1995, as  supplemented
June 1, 1995,  which has been filed with the Securities and Exchange  Commission
and is incorporated by reference into this  prospectus.  For a free copy, or for

<F1>Class B shares  purchased on or after June 1, 1995 convert tax free to Class A shares after eight years.  See "Class B Shares"
    for more information.
<F2>Class C shares are  available  only  through  dealers who have  entered into special  distribution  agreements  with  Keystone
    Investment Distributors Company, the Fund's principal underwriter.
<F3>The sales charge applied to purchases of Class A shares  declines as the amount invested  increases.  See  "Alternative  Sales
    Options."
<F4>Purchases of Class A shares in the amount of  $1,000,000 or more and/or  purchases  made by certain  qualifying  retirement or
    other plans are not subject to a sales charge, but may be subject to a contingent  deferred sales charge. See "Class A Shares"
    and "Contingent Deferred Sales Charge and Waiver of Sales Charges" for an explanation of the charge.
<F5>There is no exchange fee for exchange  orders  received by the Fund directly from a  shareholder  over the Keystone  Automated
    Response Line ("KARL"). (For a description of KARL, see "Shareholder Services.")
<F6>Expense  ratios  shown above are for the ten month  period  ended  October 31, 1994  (annualized).  Absent  voluntary  expense
    limitations,  expense  ratios for the fiscal  period ended October 31, 1994 for the Fund's Class A, B, and C shares would have
    been 2.25%, 3.03% and 3.03%, respectively.
<F7>Long term shareholders may pay more than the economic equivalent of the maximum front end sales charges otherwise permitted by
    the National Association of Securities Dealers, Inc. ("NASD").
<F8>The Securities and Exchange Commission  requires use of a 5% annual return figure for purposes of this example.  Actual return
    for the Fund may be greater or less than 5%.

<F1>Figures are net of expense  reimbursement by Keystone  Investment  Management  Company in connection with voluntary expense
    limitations. Before the expense reimbursement, the "Ratio of operating and management expenses to average net assets" would
    have been 2.25%,  3.12%, 2.50%, 2.15% and 2.47% for the period from January 1, 1994 to October 31, 1994 and the years ended
    December 31, 1993, 1992, 1991 and 1990, respectively.
<F2>Annualized.
<F3>Effective January 1, 1993, the Fund adopted Statement of Position 93-2: "Determination, Disclosure, and Financial Statement
    Presentation  of  Income,  Capital  Gain and  Return  of  Capital  Distributions  by  Investment  Companies."  As a result,
    distribution  amounts  exceeding  book  basis net  investment  income (or tax basis net  income on a  temporary  basis) are
    presented as "Distributions in excess of investment income -- net." Similarly, capital gain distributions in excess of book
    basis capital gains (or tax basis capital gains on a temporary basis) are presented as  "Distributions in excess of capital
    gains."  For the fiscal  years ended  December  31,  1992 and 1990,  distributions  in excess of book basis net income were
    charged to paid-in capital.

THE FUND
  The Fund is an open-end,  management  investment company,  commonly known as a
mutual fund, and is authorized to issue series of shares representing portfolios
of its assets, some or all of which portfolios may be diversified. At this time,
the  Fund  issues  shares  of  one  nondiversified  portfolio,  the  World  Bond
Portfolio. The Fund was formed as a Massachusetts business trust on September 5,
1986.  The Fund is one of the  thirty  funds  managed  or  advised  by  Keystone
Investment  Management  Company (formerly named Keystone  Custodian Funds, Inc.)
("Keystone"), the Fund's investment adviser.

INVESTMENT OBJECTIVES AND POLICIES
  The Portfolio seeks current income by investing  primarily in a nondiversified
portfolio  consisting  of  debt  securities  denominated  in  U.S.  and  foreign
currencies. The Portfolio seeks capital appreciation as a secondary objective.

NORMAL MARKET CONDITIONS POLICY
  The Portfolio invests at least 65% of its total assets in bonds denominated in
at least three currencies,  one of which may be United States ("U.S.") currency.
This policy is fundamental and may not be changed without obtaining the approval
of the  Portfolio's  shareholders.  While  the  Portfolio's  fundamental  policy
requires it to invest at least 65% of its total assets in bonds  denominated  in
at least three currencies, it is expected that under normal market conditions in
excess  of 80% of  the  Portfolio's  total  assets  will  be  invested  in  debt
securities denominated in U.S. and foreign currencies. COUNTRY OF ISSUER POLICY
  Under normal market  conditions,  at least 65% of the Portfolio's total assets
will also be invested in the securities of issuers  located in three  countries,
one of which may be the U.S.  The  Portfolio  may, and the  Portfolio's  adviser
intends to, invest up to 35% of its assets in the securities of issuers  located
in "emerging" or "developing" market countries. For this purpose, countries with
emerging or developing  markets are generally  those where the per capita income
is in the low to middle  ranges,  as  determined by the  International  Bank for
Reconstruction and Development ("World Bank").

DEFENSIVE POLICY
  When, in the opinion of the Portfolio's investment adviser,  market conditions
warrant,  the Portfolio may for defensive purposes  temporarily invest more than
35% of its  total  assets  in money  market  instruments,  cash  and  government
securities denominated in U.S. and foreign currencies. Under circumstances where
the Portfolio is investing for  defensive  purposes,  it may not be pursuing its
investment objectives.

NONDIVERSIFICATION POLICY
  The Portfolio will attempt to vary its  investments  among issuers  located in
different  countries as indicated above, but reserves  authority to invest up to
25% of its total assets in  obligations  issued or guaranteed by any one foreign
government and up to 10% of its total assets in obligations issued or guaranteed
by any one multinational agency.

  In allocating the Portfolio's  investments  among issuers located in different
countries,  the Portfolio's  adviser will take into  consideration  the interest
rate  environments  and general economic  conditions of such countries.  It will
also  evaluate  the  relative  values of  different  currencies  on the basis of
technical and political data and such fundamental economic criteria, as relative
inflation rates and trends,  projected growth rates,  balance of payments status
and economic policies.

  The  debt  securities  in  which  the  Portfolio  may  invest  include  bonds,
debentures, notes, commercial paper, certificates of deposit, obligations issued
or  guaranteed  by the U.S. or a foreign  government  or any of their  political
subdivisions,  agencies or  instrumentalities,  and debt securities  convertible
into common stock.

  At least 65% of the debt  securities  selected for the Portfolio will be rated
BAA or higher by Moody's Investors Service, Inc. ("Moody's") or BBB or higher by
Standard & Poor's  Corporation  ("S&P") or, if unrated,  will be deemed to be of
comparable quality by the Portfolio's adviser.

  Bonds  rated BAA or higher by Moody's  or BBB or higher by S&P are  considered
investment  grade  bonds and are  generally  considered  medium to high  quality
obligations  of the issuer.  Such bonds  generally have  protections  for timely
interest  payments and repayment of principal.  Bonds rated in the lower part of
these  ratings,  however,  may  have  some  speculative   characteristics.   Any
split-rated bond in which the Portfolio may invest will be rated at least BAA by
Moody's or BBB by S&P.

  Bonds  that are  rated  BAA by  Moody's  are  considered  to be  medium  grade
obligations,  i.e.,  they are  neither  highly  protected  nor  poorly  secured.
Interest  payments and principal  security appear adequate for the present,  but
certain  protective  elements  may  be  lacking  or  may  be  characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics  and in fact have  speculative  characteristics  as well.  Bonds
rated BBB by S&P are regarded as having an adequate capacity to pay interest and
repay  principal.   While  such  bonds  normally  exhibit  adequate   protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
bonds in this category than in higher rated categories.

  The balance of the debt  securities  held by the  Portfolio may be rated below
BAA by Moody's or below BBB by S&P. Such bonds are commonly referred to as "junk
bonds." For a discussion of the investment  risks associated with investments in
such bonds, see the "Risk Factors" section of this prospectus.

  The value of the Portfolio's  investments  will vary inversely with changes in
prevailing  interest  rates  and  changes  in the  value of the U.S.  dollar  in
relation to foreign  currencies.  Because of these  factors,  investment in debt
obligations  may provide an opportunity for capital  appreciation  when interest
rates are expected to decline.

  Investing  in  a  nondiversified   portfolio,  as  opposed  to  a  diversified
portfolio,  may result in a greater degree of exposure to the economic movements
of the  market  sector in which the  Portfolio  invests.  Investment  in foreign
securities also involves other risks,  which are described under "Risk Factors."

EQUITY POLICY
  The Portfolio, consistent with achieving its investment objectives, may invest
up to 35% of its total assets in dividend-  paying  equity  securities,  such as
common stocks or preferred stocks, including convertible preferred stock, and in
the other instruments described herein.

OTHER ELIGIBLE SECURITIES
  The Portfolio may enter into  repurchase  agreements  with respect to U.S. and
foreign  government  securities for the purpose of investing cash balances.  The
Portfolio may purchase or sell foreign  currency,  purchase  options on currency
and  purchase or sell  forward  foreign  currency  exchange  contracts to manage
exchange  rates.  In  addition,  the  Portfolio  may write  covered call and put
options and purchase call and put options on any security in which the Portfolio
may invest,  including the purchase of options to close out  previously  written
options of the same series.  The Portfolio may, for hedging  purposes,  purchase
and sell futures  contracts and put and call options on futures  contracts.  The
Portfolio may purchase  securities on a when-issued or forward  commitment basis
and may engage in the lending of portfolio securities.

  The Portfolio is authorized to enter into forward currency exchange  contracts
if, as a result,  no more than 75% of the value of the investing  classes of the
Portfolio would be committed to the  consummation  of such contracts;  provided,
however,  that the Fund has satisfied the requirements imposed by the Securities
and Exchange Commission under the Investment Company Act of 1940 ("1940 Act").

  In addition to the options, futures contracts and forwards mentioned above, if
consistent  with its  investment  objective,  the  Portfolio  may also invest in
certain other types of derivative instruments, including collateralized mortgage
obligations,  structured notes, interest rate swaps, index swaps, currency swaps
and caps and floors.  These vehicles can also be combined to create more complex
products called hybrid derivatives or structured securities.

  The  Portfolio  intends to follow  policies  of the  Securities  and  Exchange
Commission  as they are  adopted  from time to time  with  respect  to  illiquid
securities,  including, at this time, (1) treating as illiquid,  securities that
may not be sold or disposed of in the ordinary  course of business  within seven
days at  approximately  the  value  at  which  the  Portfolio  has  valued  such
securities on its books, and (2) limiting its holdings of such securities to 15%
of net assets.

  For  further  information  about  the  types  of  investments  and  investment
techniques  available to the Portfolio,  including the associated risks, see the
section of this prospectus entitled "Additional Investment  Information" and the
statement of additional information.

  If the Portfolio's investment objectives change,  shareholders should consider
whether the Portfolio is still an appropriate  investment in light of their then
current financial positions and needs.

  Of course,  there can be no  assurance  that the  Portfolio  will  achieve its
investment objectives since there is uncertainty in every investment.

NATURE OF INVESTMENT OBJECTIVES
  The Portfolio's  investment  objectives are  nonfundamental and may be changed
without the vote of a majority of the shareholders. If the investment objectives
are changed and a  shareholder  determines  that the  Portfolio  is no longer an
appropriate  investment,  the  shareholder  may  redeem his  shares,  but may be
subject to a contingent deferred sales charge upon redemption.

INVESTMENT RESTRICTIONS
  The Fund has adopted the fundamental  restrictions  summarized below on behalf
of its  portfolios,  which may not be changed without the approval of a majority
(as  defined  in the 1940  Act) of the  portfolio's  outstanding  shares.  These
restrictions and certain other fundamental and  nonfundamental  restrictions are
contained in the statement of additional information.

  Generally,  the Portfolio may not do the following:

    (1)  purchase  securities  of any one issuer if as a result more than 10% of
  the  outstanding  voting  secutities  of  such  issuer  would  be  held by the
  Portfolio,  or invest more than 5% of the  Portfolio's  total assets (taken at
  market value) in the securities of any one issuer, except securities issued or
  guaranteed by the U.S. government or any of its agencies or instrumentalities,
  provided  that the  Portfolio  may  invest  up to 25% of its  total  assets in
  securities issued or guaranteed by any single foreign government and up to 10%
  of its  total  assets  in  securities  issued  or  guaranteed  by  any  single
  multinational agency;

    (2) borrow  money,  except from a bank for  temporary or emergency  purposes
  (not for  leveraging  or  investment)  and may not  borrow  money in an amount
  exceeding  one-third of the value of its total assets (less  liabilities other
  than  borrowings);  any  borrowings  that  come  to  exceed  one-third  of the
  Portfolio's  total assets by reason of a decline in net assets will be reduced
  within  three  days to the  extent  necessary  to  comply  with the  one-third
  limitation;  the Portfolio will not purchase  securities  while temporary bank
  borrowings in excess of 5% of its total assets are outstanding; and

    (3)  invest  more than 25% of its total  assets  (taken at market  value) in
  securities of issuers in a particular industry or group of related industries,
  except U.S. government securities.

RISK FACTORS
  Investing in the Portfolio  involves the risk inherent in any  investment in a
security,  i.e.,  the net  asset  value of a share of the Fund can  increase  or
decrease in response to changes in economic  conditions,  interest rates and the
market's perception of the underlying securities of the Portfolio.

FOREIGN SECURITIES
  In addition, investing in the
Portfolio,  with its globally  varied  investments,  involves  greater risk than
investing in a fund with a portfolio consisting solely of securities of domestic
issuers for the following reasons:

    (1) there may be less public  information  available about foreign companies
  than is available about U.S. companies;

    (2) foreign companies are not generally  subject to the uniform  accounting,
  auditing and financial  reporting  standards and practices  applicable to U.S.
  companies;

    (3) foreign  stock  markets have less volume than the U.S.  market,  and the
  securities  of some foreign  companies  are less liquid and more volatile than
  the securities of comparable U.S. companies;

    (4)  foreign   securities   transactions   may  involve   higher   brokerage
  commissions;

    (5) there may be less  government  regulation of stock  exchanges,  brokers,
  listed companies and banks in foreign countries than in the U.S.;

    (6) the  Portfolio  may incur  fees on  currency  exchanges  when it changes
  investments from one country to another;

    (7) the Portfolio's  foreign investments could be affected by expropriation,
  confiscatory  taxation,  nationalization,  establishment of exchange controls,
  political or social instability or diplomatic developments;

    (8) foreign governments may withhold income on investments; and

    (9)  fluctuations  in foreign  exchange  rates will  affect the value of the
  Portfolio's investments, the value of dividends and interest earned, gains and
  losses  realized  on  the  sale  of  securities,  net  investment  income  and
  unrealized   appreciation  or   depreciation  of  investments.

  Investing in  securities  of issuers in emerging  markets  countries  involves
exposure to  economic  systems  that are  generally  less  mature and  political
systems that are  generally  less stable than those of developed  countries.  In
addition,  investing in companies in emerging markets countries may also involve
exposure to national  policies that may restrict  investment  by foreigners  and
undeveloped legal systems governing private and foreign  investments and private
property.  The  typically  small size of the  markets for  securities  issued by
companies  in  emerging  markets  countries  and  the  possibility  of a low  or
nonexistent  volume of trading in those  securities may also result in a lack of
liquidity and in price volatility of those securities.

 NONINVESTMENT GRADE BONDS
  The Portfolio may invest up to 35% of its assets in high  yielding,  high risk
bonds  and  other  similar  securities  commonly  referred  to as "junk  bonds."
Investment  in such  bonds  involves  risks that are  greater  than the risks of
investing in higher quality debt securities and may result in greater upward and
downward  movement  of the net  asset  value per  share of the  Portfolio.  As a
result,  such risks should be carefully  considered by  investors.  These risks,
discussed in greater detail below, include risks from:

    (1) interest rate fluctuations;

    (2) changes in credit status,  including  weaker overall credit condition of
  issuers and risks of default;

    (3) industry, market and economic risk;

    (4) volatility of price  resulting from broad and rapid changes in the value
  of underlying securities; and

    (5)  greater  price  variability  and  credit  risks of  certain  high yield
  securities such as zero coupon bonds and payment-in-kind bonds ("PIKs").

  More specifically, investors should be aware of the following risks:

     (1)  Securities  rated BB or lower  by S&P or BA or  lower by  Moody's  are
  considered predominantly speculative with respect to the ability of the issuer
  to meet principal and interest payments.

    (2) The lower ratings of certain  securities held by the Portfolio reflect a
  greater  possibility  that adverse  changes in the financial  condition of the
  issuer, or in general economic  conditions,  or both, or an unanticipated rise
  in interest  rates,  may impair the ability of the issuer to make  payments of
  interest and  principal,  especially if the issuer is highly  leveraged.  Such
  issuer's ability to meet its debt  obligations may also be adversely  affected
  by specific corporate developments, or the issuer's inability to meet specific
  projected business forecasts,  or the unavailability of additional  financing.
  Also, an economic  downturn or an increase in interest  rates may increase the
  potential for a default by the issuers of these securities.

    (3) The  value  of  certain  securities  held by the  Portfolio  may be more
  susceptible  to  real or  perceived  adverse  economic,  company  or  industry
  conditions and publicity than is the case for higher quality securities.

    (4) The  values of certain  securities,  like  those of other  fixed  income
  securities,  fluctuate in response to changes in interest rates. When interest
  rates decline,  the value of a portfolio  invested in bonds can be expected to
  rise. Conversely,  when interest rates rise, the value of a portfolio invested
  in bonds can be expected to decline. For example, in the case of an investment
  in a fixed income  security,  if interest rates increase after the security is
  purchased,  the security, if sold prior to maturity, may return, less than its
  cost. The prices of  noninvestment  grade bonds,  however,  are generally less
  sensitive to interest rate changes than higher rated bonds, but more sensitive
  to adverse or positive economic changes or individual corporate  developments.
  With respect to derivative or structured securities,  the market value of such
  securities may vary depending on the manner in which such securities have been
  structured.  As a result,  the value of such  investments may change at a more
  rapid rate than that of traditional fixed income securities.

    (5) The secondary market for certain securities held by the Portfolio may be
  less liquid at certain times than the secondary market for higher quality debt
  securities,  which  may  have  an  adverse  effect  on  market  price  and the
  Portfolio's  ability to dispose of particular issues and may also make it more
  difficult for the Portfolio to obtain accurate market  quotations for purposes
  of valuing its assets.

    (6) Zero coupon bonds and PIKs involve  additional  special  considerations.
  For  example,  zero  coupon  bonds do not  require  the  periodic  payment  of
  interest.  PIK bonds are debt obligations that provide that the issuer may, at
  its option,  pay  interest on such bonds in cash or in the form of  additional
  debt obligations. Such investments may experience greater fluctuation in value
  due to  changes  in  interest  rates than debt  obligations  that pay  current
  interest currently.  Even though these investments do not pay current interest
  in cash,  the  Portfolio  is,  nonetheless,  required  by tax  laws to  accrue
  interest  income on such  investments  and to distribute such amounts at least
  annually to  shareholders.  Thus the  Portfolio  could be required at times to
  liquidate  investments  in  order  to  fulfill  its  intention  to  distribute
  substantially  all of its net income as dividends.  The Portfolio  will not be
  able to purchase additional income producing securities with cash used to make
  such  distributions,  and its direct  income  may be reduced as a result.

  The Portfolio  may invest in securities  that are rated as low as D by S&P and
C- by Moody's.  It is possible for securities  rated D or C-,  respectively,  to
have  defaulted  on  payments  of  principal  and/or  interest  at the  time  of
investment.  The  section of this  prospectus  entitled  "Additional  Investment
Information" describes these rating categories.  The Portfolio intends to invest
in D rated  debt only in cases  where,  in the  adviser's  judgment,  there is a
distinct prospect of improvement in the issuer's  financial position as a result
of the completion of reorganization or otherwise.  The Portfolio may also invest
in unrated securities that, in the adviser's  judgment,  offer comparable yields
and risks to those of securities  that are rated,  as well as in  non-investment
quality zero coupon bonds and PIKs.

RULE 144A SECURITIES
  The  Portfolio  may  invest in  restricted  securities,  including  securities
eligible for resale  pursuant to Rule 144A under the Securities Act of 1933 (the
"1933  Act").   Generally,   Rule  144A  establishes  a  safe  harbor  from  the
registration  requirements  of the 1933 Act for  resales by large  institutional
investors of  securities  not  publicly  traded in the U.S.  The  Portfolio  may
purchase  Rule  144A  securities  when such  securities  present  an  attractive
investment  opportunity and otherwise meet the Portfolio's  selection  criteria.
The Board of Trustees has adopted  guidelines and  procedures  pursuant to which
the liquidity of the Portfolio's Rule 144A securities is determined by Keystone,
the   Portfolio's   adviser.   The  Board  of   Trustees   monitors   Keystone's
implementation of such guidelines and procedures.

  At the present time, the Portfolio cannot  accurately  predict exactly how the
market for Rule 144A  securities  will  develop.  A Rule 144A  security that was
readily  marketable upon purchase may subsequently  become illiquid.  In such an
event, the Board of Trustees will consider what action, if any, is appropriate.

PRICING SHARES
  The net asset value of a share of the  Portfolio is computed each day on which
the New York Stock Exchange (the  "Exchange") is open as of the close of trading
on the  Exchange  (currently  4:00 p.m.  eastern time for the purpose of pricing
Portfolio  shares)  except on days when changes in the value of the  Portfolio's
securities do not affect the current net asset value of its shares. The Exchange
currently is closed on weekends,  New Year's Day,  Presidents' Day, Good Friday,
Memorial Day,  Independence Day, Labor Day,  Thanksgiving Day and Christmas Day.
The net asset value per share of the Portfolio is arrived at by determining  the
value of the  Portfolio's  assets,  subtracting its liabilities and dividing the
result by the number of its shares outstanding.

  Current values for the Portfolio's securities are determined as follows:

    (1) common stock,  preferred stock and other equity securities listed on the
  Exchange  are valued on the basis of the last sale price on the  Exchange;  in
  the absence of any sales,  such  securities are valued at the mean between the
  closing asked price and the closing bid price;

    (2) common  stock,  preferred  stock and other equity  securities  listed on
  other U.S. or foreign  exchanges  will be valued as described in paragraph (1)
  using  quotations  on the exchange on which the  security is most  extensively
  traded;

    (3) common stock,  preferred stock and other equity securities  unlisted and
  quoted on the  National  Market  System  ("NMS")  are  valued at the last sale
  price,  provided  a sale has  occurred;  in the  absence  of any  sales,  such
  securities  are valued at the high or "inside" bid supplied by the NASD on its
  NASDAQ system for securities traded in the over-the-counter market;

    (4) common stock,  preferred stock and other equity securities quoted on the
  NASDAQ system, but not listed on NMS, are valued at the high or "inside" bid;

    (5) common stock, preferred stock and other equity securities not listed and
  not quoted on the NASDAQ system for which  over-the-counter  market quotations
  are readily available are valued at the mean between the current bid and asked
  prices for such securities;

    (6) non-U.S.  common stock,  preferred stock and other equity securities not
  listed or listed  and  subject  to  restrictions  on sale are valued at prices
  supplied by a dealer selected by the Portfolio's adviser;

    (7) bonds,  debentures and other debt  securities,  whether or not listed on
  any national securities exchange,  are valued at a price supplied by a pricing
  service or a bond dealer selected by the Portfolio's adviser;

    (8)  short-term  instruments  having  maturities of more than sixty days for
  which market  quotations  are readily  available are valued at current  market
  value; where market quotations are not available,  such instruments are valued
  at fair value as determined by the Fund's Board of Trustees;

    (9) short-term  instruments  purchased with maturities of sixty days or less
  (including  all master  demand notes) are valued at amortized  cost  (original
  purchase  cost as  adjusted  for  amortization  of  premium  or  accretion  of
  discount),  which, when combined with accrued interest,  approximates  market;
  short-term  instruments  maturing in more than sixty days when  purchased  and
  held on the  sixtieth  day prior to  maturity  are  valued at  amortized  cost
  (market  value on the sixtieth day  adjusted  for  amortization  of premium or
  accretion  of  discount),   which,   when  combined  with  accrued   interest,
  approximates market and, in any case, reflects fair value as determined by the
  Fund's Board of Trustees;

    (10) options, futures contracts and options on futures listed or traded on a
  national  securities  exchange  are  valued  at the  last  sale  price on such
  exchange  prior to the time of  determining  net asset value or, if no sale is
  reported, are valued at the mean between the most recent bid and asked prices;

    (11) forward currency contracts are valued at their last sale as reported by
  a pricing service, and in the absence of a report at a value determined on the
  basis of the underlying currency at prevailing exchange rates;

    (12)  securities  subject to restrictions on resale are valued at fair value
  at least monthly by a pricing  service under the direction of the Fund's Board
  of Trustees; and

    (13) all other  assets are valued at fair market value as  determined  by or
  under the direction of the Fund's Board of Trustees.

DIVIDENDS AND TAXES
  The  Portfolio  has  qualified  and  intends  to  qualify  in the  future as a
regulated  investment  company under the Internal  Revenue  Code.  The Portfolio
qualifies if, among other things,  it distributes to its  shareholders  at least
90% of its net investment income for its fiscal year. The Portfolio also intends
to make timely  distributions,  if necessary,  sufficient in amount to avoid the
nondeductible  4% excise tax  imposed on a regulated  investment  company to the
extent that it fails to distribute, with respect to each calendar year, at least
98% of its  ordinary  income for such  calendar  year and 98% of its net capital
gains for the one-year  period ending on October 31 of such calendar  year.  Any
taxable  distributions  would be declared in October,  November,  or December to
shareholders  of record in such a month and paid by the  following  January  31.
Such  distributions  would be taxable  income to a  shareholder  for the year in
which the  distributions  were  declared.  If the Portfolio  qualifies and if it
distributes  substantially  all of its net  investment  income  and net  capital
gains,  if any, to  shareholders,  it will be relieved of any federal income tax
liability.

  The  Fund  declares  and  distributes   dividends  from  the  Portfolio's  net
investment  income monthly.  Distributions  of short-term and long-term  capital
gains,  if any,  will  be made at  least  annually.  Shareholders  receive  Fund
distributions  in the form of  additional  shares of that  class of shares  upon
which the distribution is based or, at the  shareholder's  option, in cash. Fund
distributions  in the form of  additional  shares  are made at net  asset  value
without the imposition of a sales charge.

  Because Class A shares bear most of the costs of  distribution  of such shares
through  payment of a front end sales  charge  while  Class B and Class C shares
bear  such  expenses  through  a  higher  annual   distribution   fee,  expenses
attributable  to Class B shares and Class C shares will generally be higher than
those attributable to Class A shares, and income  distributions paid by the Fund
with  respect to Class A shares will  generally  be greater than those paid with
respect to Class B and Class C shares.

  Income  dividends  and net  short-term  gains  distributions  are  taxable  as
ordinary  income and net long-term  gains  distributions  are taxable as capital
gains regardless of how long Fund shares have been held. However, if Fund shares
held for less than six months are sold at a loss,  such loss will be treated for
tax purposes as a long-term  capital loss to the extent of any long-term capital
gains  dividends  received.  The Fund  advises  shareholders  annually as to the
federal tax status of all  distributions  made during the year.

FUND MANAGEMENT AND EXPENSES

BOARD OF TRUSTEES
  Under  Massachusetts  law,  the Fund's  Board of  Trustees  has  absolute  and
exclusive control over the management and disposition of all assets of the Fund.
Subject to the authority of the Fund's Board of Trustees,  Keystone,  the Fund's
adviser,  provides investment advice,  management and administrative services to
the Fund.

INVESTMENT ADVISER

  Keystone,  located at 200 Berkeley Street, Boston,  Massachusetts  02116-5034,
has provided investment advisory and management services to investment companies
and private accounts since it was organized in 1932. Keystone is a wholly- owned
subsidiary of Keystone  Investments,  Inc. (formerly named Keystone Group, Inc.)
("Keystone Investments"),  located at 200 Berkeley Street, Boston, Massachusetts
02116- 5034.

  Keystone  Investments  is a  corporation  predominantly  owned by current  and
former  members of  management  of Keystone  and its  affiliates.  The shares of
Keystone Investments common stock beneficially owned by management are held in a
number of voting trusts, the trustees of which are George S. Bissell,  Albert H.
Elfner, III, Edward F. Godfrey and Ralph J. Spuehler,  Jr. Keystone  Investments
provides  accounting,   bookkeeping,  legal,  personnel  and  general  corporate
services to Keystone,  its  affiliates  and the Keystone  Investments  Family of
Funds.

  Under  its  Investment  Advisory  and  Management   Agreement  (the  "Advisory
Agreement")  with the Fund,  Keystone manages the investment and reinvestment of
the  Portfolio's  assets,  supervises  the  operation of the Fund,  provides all
necessary office space, facilities, equipment and personnel and arranges, at the
request of the Fund,  for its  employees  to serve as  officers or agents of the
Fund.

  The  Portfolio  pays  Keystone a fee for its  services at the annual rates set
forth below:

                                                           Aggregate Net Asset
Management                                                 Value of the Shares
Fee                                 Income                    of the Portfolio
- ------------------------------------------------------------------------------
1.5% of Gross Income plus
0.50% of the first                                        $  500,000,000, plus
0.45% of the next                                         $  500,000,000, plus
0.40% of amounts over                                     $1,000,000,000

  Keystone's  fee is computed as of the close of business on each  business  day
and payable daily.

  For the fiscal period ended October 31, 1994,  the Portfolio  paid to Keystone
management fees of $61,697,  which represented 0.50% of the Portfolio's  average
net assets on an annualized basis.

  To the extent the Portfolio's  management fee exceeds 0.75%,  the fee would be
higher than that paid by most other  investment  companies.  The Portfolio's fee
structure is  comparable,  however,  to that of other  global and  international
funds  subject  to  the  higher  costs  involved  in  managing  a  portfolio  of
predominantly international securities.

  The Advisory  Agreement  continues in effect from year to year only so long as
such continuance is specifically  approved at least annually by the Fund's Board
of Trustees or by vote of a majority of the  outstanding  shares of the Fund. In
either case, the terms of the Advisory Agreement and continuance thereof must be
approved  by the vote of a  majority  of  Independent  Trustees  in  person at a
meeting  called  for the  purpose  of  voting  on such  approval.  The  Advisory
Agreement may be terminated,  without penalty, on 60 days' written notice by the
Fund or Keystone.  The Advisory Agreement will terminate  automatically upon its
assignment.

FUND EXPENSES
  The  Portfolio  will pay all of its  expenses.  In addition to the  investment
advisory,  management and Distribution Plan fees discussed herein, the principal
expenses the Portfolio is expected to pay include its share  (currently 100%) of
the expenses of certain Trustees;  the Fund's transfer,  dividend disbursing and
shareholder servicing agent expenses; the Fund's custodian expenses; fees of the
Fund's  accountants,  as well as legal  counsel  to the  Fund's  Trustees;  fees
payable to government  agencies,  including  registration and qualification fees
attributable to the Fund and its shares under federal and state securities laws;
and certain extraordinary  expenses. In addition, each class will pay all of the
expenses attributable to it. Such expenses are currently limited to Distribution
Plan  expenses.  The  Portfolio  also pays its brokerage  commissions,  interest
charges and taxes.

  For the fiscal period ended October 31, 1994, the Portfolio's Class A expenses
represented 1.83% of its average net assets or 2.20% on an annualized basis. For
the period ended October 31, 1994, the Portfolio's Class B expenses  represented
2.46% of its average net assets or 2.95% on an  annualized  basis.  For the same
period,  the Portfolio's  Class C expenses  represented 2.46% of its average net
assets or 2.95% on an annualized  basis.  These percentages are after Keystone's
reimbursement  of certain of the Fund's expenses  pursuant to voluntary  expense
limitations  that were in effect for the fiscal  period ended  October 31, 1994,
which  limitations  Keystone  maintained  until December 31, 1994. In connection
with such voluntary expense limits,  Keystone reimbursed the Fund $2,943, $2,200
and $1,119 for Class A, Class B and Class C shares, respectively. Keystone would
not be required to  reimburse  the Fund to the extent such  reimbursement  would
result in the Fund's  inability  to qualify as a  regulated  investment  company
under the Internal Revenue Code.

  During the ten month period  ended  October 31, 1994,  the  Portfolio  paid or
accrued to Keystone Investor Resource Center, Inc. ("KIRC"), the Fund's transfer
and dividend paying agent,  $13,654 for certain accounting and printing services
and $32,493 for transfer agent  services.  KIRC is a wholly-owned  subsidiary of
Keystone.

  The Fund has  adopted  a Code of Ethics  incorporating  policies  on  personal
securities trading as recommended by the Investment Company
Institute.

PORTFOLIO MANAGER

  Gilman C. Gunn is the Fund's portfolio manager.  Mr. Gunn is a Keystone Senior
Vice  President  and Group Head.  An  investment  professional  with 22 years of
experience, he has spent over ten years in London, Kuwait and Thailand.

SECURITIES TRANSACTIONS
  Under policies  established by the Board of Trustees,  the Portfolio's adviser
selects  broker-dealers to execute  transactions  subject to the receipt of best
execution. When selecting broker-dealers to execute portfolio transactions,  the
Portfolio's  adviser  may  consider  as a factor  the  number  of  shares of the
Portfolio  sold by such  broker-dealer.  In addition,  broker-dealers  executing
portfolio  transactions  may, from time to time,  be  affiliated  with the Fund,
Keystone, the Fund's principal underwriter or their affiliates.

  The  Portfolio  may pay higher  commissions  to  broker-dealers  that  provide
research services.  Keystone may use these services in advising the Portfolio as
well as in advising its other clients.

PORTFOLIO TURNOVER
  The Portfolio's turnover rates for the fiscal year ended December 31, 1993 and
the ten month  period ended  October 31, 1994 were 107% and 100%,  respectively.
High portfolio turnover involves  correspondingly  greater brokerage commissions
and other  transaction  costs,  which will be borne directly by the Portfolio as
well  as  additional  gains  and/  or  losses.   The  Portfolio  pays  brokerage
commissions in connection  with the writing of options and effecting the closing
purchase  or sale  transactions  as well as for  some  purchases  and  sales  of
portfolio securities.

HOW TO BUY SHARES

  You may purchase  shares of the Portfolio  from any  broker-dealer  that has a
selling agreement with Keystone Investment  Distributors Company (formerly named
Keystone Distributors, Inc.) (the "Principal Underwriter"), the Fund's principal
underwriter.  The Principal Underwriter,  a wholly-owned subsidiary of Keystone,
is located at 200 Berkeley Street, Boston, Massachusetts 02116- 5034.

  In  addition,  you may open an  account  for the  purchase  of  shares  of the
Portfolio by mailing to the Fund c/o Keystone  Investor  Resource Center,  Inc.,
P.O. Box 2121, Boston, Massachusetts 02106-2121, a completed account application
and a check,  payable to the Fund.  You may also open an account by  telephoning
1-800-  343-2898  to obtain  the  number of an  account to which you can wire or
electronically   transfer  funds,  and  then  sending  in  a  completed  account
application.  Subsequent  investments  in Portfolio  shares in any amount may be
made by check,  by  wiring  Federal  funds or by an  electronic  funds  transfer
("EFT").

  Orders for the purchase of shares of the Fund will be confirmed at an offering
price equal to the net asset value per share next  determined  after  receipt of
the order in proper form by the Principal Underwriter (generally as of the close
of the  Exchange  on that day)  plus,  in the case of Class A shares,  the sales
charge.  Orders  received  by dealers or other  firms  prior to the close of the
Exchange and  received by the  Principal  Underwriter  prior to the close of its
business day will be confirmed at the offering  price  effective as of the close
of the Exchange on that day.

  Orders for shares  received,  other than as stated  above,  will  receive  the
offering price equal to the net asset value per share next determined (generally
the next business day's offering price) plus, in the case of Class A shares, the
sales charge.

  An initial  purchase must be at least $1,000.  There is no minimum  amount for
subsequent  purchases.  The Fund  reserves the right to determine  the net asset
value more  frequently  than once a day if deemed  desirable.  Dealers and other
financial services firms are obligated to transmit orders promptly.

  The Fund  reserves the right to withdraw all or any part of the offering  made
by this prospectus and to reject purchase orders.

  Shareholder  inquiries  should  be  directed  to KIRC  by  calling  toll  free
1-800-343-2898  or writing to KIRC or to the firm from which this prospectus was
received.

ALTERNATIVE SALES OPTIONS
  Generally, the Fund offers three classes of shares:

CLASS A SHARES -- FRONT END LOAD OPTION
  Class A shares are sold with a sales charge at the time of  purchase.  Class A
shares  are not  subject  to a sales  charge  when they are  redeemed  except as
follows:  Class A shares  purchased  on or after April 10, 1995 (1) in an amount
equal to or exceeding $1,000,000 or (2) by a corporate qualified retirement plan
or a non-qualified  deferred compensation plan sponsored by a corporation having
100 or more eligible  employees (a "Qualifying  Plan"), in either case without a
front end sales charge,  will be subject to a contingent  deferred  sales charge
for the 24 month period  following the date of purchase.  Certain Class A shares
purchased prior to April 10, 1995 may be subject to a deferred sales charge upon
redemption  during the one year period  following the date of purchase.

CLASS B SHARES -- BACK END LOAD OPTION
  Class B shares are sold without a sales  charge at the time of  purchase,  but
are,  with certain  exceptions,  subject to a deferred  sales charge if they are
redeemed.  Class B shares  purchased  on or after June 1, 1995 are  subject to a
deferred sales charge upon redemption  during the 72 month period  following the
month of purchase. Class B shares purchased prior to June 1, 1995 are subject to
a deferred sales charge upon redemption during the four calendar years following
purchase.  Class B shares  purchased  on or after  June 1,  1995  that have been
outstanding for eight years  following the month of purchase will  automatically
convert to Class A shares  without  imposition  of a front-end  sales  charge or
exchange fee. Class B shares  purchased  prior to June 1, 1995 will retain their
existing conversion rights.

CLASS C SHARES -- LEVEL LOAD OPTION
  Class C shares are sold without a sales  charge at the time of  purchase,  but
are  subject to a deferred  sales  charge if they are  redeemed  within one year
after the date of purchase.  Class C shares are available  only through  dealers
who have  entered  into  special  distribution  agreements  with  the  Principal
Underwriter.

  Each class of shares, pursuant to its Distribution Plan or other plans, as the
case may be, pays an annual service fee of 0.25% of the Fund's average daily net
assets  attributable  to that class.  In addition the Class B and C Distribution
Plans  provide for the payment of an annual  distribution  fee of up to 0.75% of
the average net assets  attributable to their respective  classes.  As a result,
income distributions paid by the Fund with respect to Class B and Class C shares
will generally be less than those paid with respect to Class A shares.

  Investors who would rather pay the entire cost of  distribution at the time of
investment,  rather than spreading  such cost over time,  might consider Class A
shares.  Depending  on the amount of the  purchase  and the  intended  length of
investment,  other investors might consider Class B or Class C shares,  in which
case  100% of the  purchase  price is  invested  immediately.  The Fund will not
normally  accept any  purchase  of Class B shares in the amount of  $250,000  or
more, and will not normally  accept any purchase of Class C shares in the amount
of $1,000,000 or more.


                   ---------------------------------------
CLASS A SHARES
  Class A shares are offered at net asset value plus an initial  sales charge as
follows:

- ---------
 *Rounded to the nearest one-hundredth percent.
                   ---------------------------------------
  Purchases  of the  Fund's  Class A shares in the  amount of $1 million or more
and/or  purchases  of Class A shares  made by a  Qualifying  Plan will be at net
asset  value  without the  imposition  of a front-end  sales  charge  (each such
purchase, an "NAV Purchase").

  With  respect  to  NAV   Purchases,   the  Principal   Underwriter   will  pay
broker/dealers  or others  concessions  based on (1) the  investor's  cumulative
purchases  during the one-year period beginning with the date of the initial NAV
Purchase and (2) the  investor's  cumulative  purchases  during each  subsequent
one-year period  beginning with the first NAV Purchase  following the end of the
prior  period.  For such  purchases,  concessions  will be paid at the following
rate:  1.00%  of the  investment  amount  up to  $2,999,999;  plus  0.50% of the
investment  amount  between  $3,000,000  and  $4,999,999;   plus  0.25%  of  the
investment amount over $4,999,999.

  Class A shares  acquired  on or after April 10,  1995 in an NAV  Purchase  are
subject to a contingent  deferred sales charge of 1.00% upon  redemption  during
the 24 month period commencing on the date the shares were originally purchased.
Certain Class A shares purchased without a front-end sales charge prior to April
10,  1995 are  subject  to a  contingent  deferred  sales  charge of 0.25%  upon
redemption  during the one year period  commencing  on the date such shares were
originally purchased.

  The sales charge is paid to the Principal Underwriter,  which in turn normally
reallows  a portion  to your  broker-dealer.  In  addition,  your  broker-dealer
currently will be paid periodic service fees at an annual rate of up to 0.25% of
the average daily net asset value of Class A shares maintained by such recipient
outstanding on the books of the Fund for specified periods.

  Upon  written  notice to  dealers  with  whom it has  dealer  agreements,  the
Principal Underwriter may reallow up to the full applicable sales
charge.

  Initial sales charges may be eliminated for persons  purchasing Class A shares
which are  included  in a managed  fee based  program (a wrap  account)  through
broker  dealers who have  entered  into special  agreements  with the  Principal
Underwriter.  Initial sales charges may be reduced or eliminated  for persons or
organizations purchasing Class A shares of the Fund alone or in combination with
Class  A  shares  of  other  Keystone  America  Funds.  See  Exhibit  A to  this
prospectus.

  Since January 1, 1995 through June 30, 1995 and upon prior notification to the
Principal  Underwriter,  Class A shares may be  purchased  at net asset value by
clients of registered  representatives within six months after the redemption of
shares of any registered  open-end investment company not distributed or managed
by Keystone or its affiliates,  where the amount invested represents  redemption
proceeds from such unrelated  registered open-end  investment  company,  and the
shareholder  either (1) paid a front end sales  charge,  or (2) was at some time
subject to, but did not actually  pay, a contingent  deferred  sales charge with
respect to the redemption proceeds.

  In addition,  upon prior  notification to the Principal  Underwriter,  Class A
shares  may  be  purchased   at  net  asset  value  by  clients  of   registered
representatives   within   six   months   after  a  change  in  the   registered
representative's  employment,  where the amount invested  represents  redemption
proceeds  from  a  registered  open-  end  management   investment  company  not
distributed or managed by Keystone or its affiliates; and the shareholder either
(1) paid a front end sales  charge,  or (2) was at some time subject to, but did
not  actually  pay, a  contingent  deferred  sales  charge  with  respect to the
redemption proceeds.

CLASS A DISTRIBUTION PLAN
  The Fund has adopted a  Distribution  Plan with  respect to its Class A shares
("Class A Distribution Plan") that provides for expenditures,  currently limited
to 0.25% annually of the average daily net asset value of Class A shares, to pay
expenses associated with the distribution of Class A shares.  Payments under the
Class A Distribution Plan are currently made to the Principal Underwriter (which
may reallow all or part to others,  such as dealers) as shareholder service fees
at an annual rate of up to 0.25% of the average daily net asset value of Class A
shares  maintained by such  recipients  outstanding on the books of the Fund for
specified periods.

CLASS B SHARES
  Class B shares are  offered  at net asset  value,  without  an  initial  sales
charge.

  With respect to Class B shares  purchased on or after June 1, 1995,  the Fund,
with certain exceptions,  imposes a deferred sales charge in accordance with the
following schedule:

                                                                   DEFERRED
                                                                    SALES
                                                                    CHARGE
REDEMPTION TIMING                                                   IMPOSED
- -----------------                                                   -------
First twelve month period following month of purchase ...........     5.00%
Second twelve month period following month of purchase ..........     4.00%
Third twelve month period following month of purchase ...........     3.00%
Fourth twelve month period following month of purchase ..........     3.00%
Fifth twelve month period following month of purchase ...........     2.00%
Sixth twelve month period following month of purchase ...........     1.00%

No deferred sales charge is imposed on amounts redeemed thereafter.

  With respect to Class B shares purchased prior to June 1, 1995, the Fund, with
certain  exceptions,  may  impose a  deferred  sales  charge  of 3.00% on shares
redeemed  during the calendar year of purchase and the first calendar year after
the year of purchase;  2.00% on shares  redeemed during the second calendar year
after  the year of  purchase;  and  1.00% on shares  redeemed  during  the third
calendar year after the year of purchase. No deferred sales charge is imposed on
amounts redeemed thereafter.

  When  imposed,  the  deferred  sales  charge is deducted  from the  redemption
proceeds  otherwise payable to you. The deferred sales charge is retained by the
Principal  Underwriter.  Amounts received by the Principal Underwriter under the
Class B Distribution  Plan are reduced by deferred sales charges retained by the
Principal Underwriter. See "Contingent Deferred Sales Charge and Waiver of Sales
Charges" below.

  Class B shares  purchased on or after June 1, 1995 that have been  outstanding
for eight years  following the month of purchase will  automatically  convert to
Class A shares (which are subject to a lower  Distribution  Plan charge) without
imposition of a front-end sales charge or exchange fee. Class B shares purchased
prior to June 1, 1995  will  similarly  convert  to Class A shares at the end of
seven calendar  years after the year of purchase.  (Conversion of Class B shares
represented  by  stock  certificates  will  require  the  return  of  the  stock
certificates to KIRC.) The Class B shares so converted will no longer be subject
to the higher expenses borne by Class B shares.  Because the net asset value per
share of the  Class A shares  may be  higher  or lower  than that of the Class B
shares at the time of conversion,  although the dollar value will be the same, a
shareholder  may receive more or fewer Class A shares than the number of Class B
shares  converted.  Under  current  law,  it is the Fund's  opinion  that such a
conversion  will not constitute a taxable event under federal income tax law. In
the event that this ceases to be the case,  the Board of Trustees  will consider
what action,  if any, is  appropriate  and in the best  interests of the Class B
shareholders.

CLASS B DISTRIBUTION PLANS
  The Fund has adopted  Distribution  Plans and other plans with  respect to its
Class B shares (all such plans collectively,  "Class B Distribution Plans") that
provide for  expenditures  at an annual rate of up to 1.00% of the average daily
net asset value of Class B shares to pay expenses of the distribution of Class B
shares.  Payments under the Class B Distribution Plans are currently made to the
Principal Underwriter (which may reallow all or part to others, such as dealers)
(1) as commissions for Class B shares sold and (2) as shareholder  service fees.
Amounts paid or accrued to the  Principal  Underwriter  under (1) and (2) in the
aggregate may not exceed the annual limitation referred to above.

  The Principal Underwriter generally reallows to brokers or others a commission
equal to 4.00% of the  price  paid for each  Class B share  sold  plus the first
year's  service fee in advance in the amount of 0.25% of the price paid for each
Class B share sold.  Beginning  approximately  12 months after the purchase of a
Class B share,  the broker or other party will receive service fees at an annual
rate of  0.25% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods. See "Distribution Plans" below.

  With respect to the Fund's Class B shares only, for the period June 1, 1995 to
August 31, 1995, the Principal  Underwriter will reallow an increased commission
equal  to  4.75%  of the  price  paid  for  each  Class  B share  sold to  those
broker/dealers or others who allow their individual  selling  representatives to
participate in the additional 0.75% commission.

CLASS C SHARES
  Class C shares are offered only through dealers who have special  distribution
agreements  with the  Principal  Underwriter.  Class C shares are offered at net
asset value, without an initial sales charge. With certain exceptions,  the Fund
may impose a deferred sales charge of 1.00% on shares  redeemed  within one year
after the date of  purchase.  No  deferred  sales  charge is  imposed on amounts
redeemed thereafter.  If imposed, the deferred sales charge is deducted from the
redemption  proceeds  otherwise  payable to a  shareholder.  The deferred  sales
charge is retained by the Principal Underwriter.  See "Contingent Deferred Sales
Charges and Waiver of Sales Charges" below.

CLASS C DISTRIBUTION PLANS
  The Fund has adopted a  Distribution  Plan and other plans with respect to its
Class C shares (all such plans collectively,  the "Class C Distribution  Plans")
that  provide for  expenditures  at an annual rate of up to 1.00% of the average
daily net asset value of Class C shares to pay expenses of the  distribution  of
Class C shares. Payments under the Class C Distribution Plans are currently made
to the Principal  Underwriter (which may reallow all or part to others,  such as
dealers) (1) as commissions for Fund shares sold and (2) as shareholder  service
fees. Amounts paid or accrued to the Principal  Underwriter under (1) and (2) in
the aggregate may not exceed the annual limitation referred to above.

  The Principal Underwriter generally reallows to brokers or others a commission
in the amount of 0.75% of the price paid for each Class C share  sold,  plus the
first year's service fee in advance in the amount of 0.25% of the price paid for
each Class C share sold,  and,  beginning  approximately  fifteen  months  after
purchase,  a commission at an annual rate of 0.75% (subject to NASD rules -- see
"Distribution   Plans")   plus   service  fees  at  an  annual  rate  of  0.25%,
respectively,  of the  average  daily  net  asset  value  of each  Class C share
maintained by such recipients outstanding on the books of the Fund for specified
periods. See "Distribution Plans" below.

CONTINGENT DEFERRED SALES CHARGE AND WAIVER OF SALES CHARGES
  Any  contingent  deferred sales charge imposed upon the redemption of Class A,
Class B or Class C shares  is a  percentage  of the  lesser of (1) the net asset
value of the shares  redeemed or (2) the net asset value at the time of purchase
of  such  shares.  No  contingent  deferred  sales  charge  is  imposed  when  a
shareholder  redeems  amounts  derived  from (1)  increases  in the  value of an
account  above the net cost of such  shares  due to  increases  in the net asset
value per share of the Fund;  (2) certain  shares with respect to which the Fund
did  not  pay a  commission  on  issuance,  including  shares  acquired  through
reinvestment  of dividend  income and capital gains  distributions;  (3) certain
Class A shares  held for more  than one year or two  years,  as the case may be,
from the date of  purchase;  (4)  Class B shares  held  during  more  than  four
consecutive  calendar  years or more than 72 months after the month of purchase,
as the case may be; or (5)  Class C shares  held for more than one year from the
date of  purchase.  Upon  request  for  redemption,  shares  not  subject to the
contingent deferred sales charge will be redeemed first. Thereafter, shares held
the longest will be the first to be redeemed.

  The Fund also may sell Class A,  Class B or Class C shares at net asset  value
without  any initial  sales  charge or a  contingent  deferred  sales  charge to
certain Directors, Trustees, officers and employees of the Fund and Keystone and
certain of their affiliates, to registered  representatives of firms with dealer
agreements with the Principal  Underwriter and to a bank or trust company acting
as a trustee for a single account.

  With respect to Class A shares  purchased  by a  Qualifying  Plan at net asset
value or Class C shares purchased by a Qualifying  Plan, no contingent  deferred
sales  charge  will  be  imposed  on any  redemptions  made  specifically  by an
individual  participant in the Qualifying  Plan. This waiver is not available in
the  event a  Qualifying  Plan (as a  whole)  redeems  substantially  all of its
assets.

  In addition, no contingent deferred sales charge is imposed on a redemption of
shares of the Fund in the event of (1) death or disability  of the  shareholder;
(2) a lump-sum  distribution  from a 401(k) plan or other benefit plan qualified
under  the  Employee  Retirement  Income  Security  Act of 1974  ("ERISA");  (3)
automatic  withdrawals  from ERISA plans if the  shareholder  is at least 59 1/2
years old; (4) involuntary redemptions of accounts having an aggregate net asset
value  of less  than  $1,000;  (5)  automatic  withdrawals  under  an  automatic
withdrawal plan of up to 1 1/2% per month of the  shareholder's  initial account
balance;  (6)  withdrawals  consisting  of loan  proceeds to a  retirement  plan
participant;  (7)  financial  hardship  withdrawals  made by a  retirement  plan
participant; or (8) withdrawals consisting of returns of excess contributions or
excess deferral amounts made to a retirement plan participant.

ARRANGEMENTS WITHBROKER-DEALERS AND OTHERS
  The  Principal  Underwriter  may,  from  time  to  time,  provide  promotional
incentives,  including  reallowance of up to the entire sales charge, to certain
dealers  whose  representatives  have sold or are  expected to sell  significant
amounts of Fund shares.  In addition,  dealers may,  from time to time,  receive
additional  cash payments.  The Principal  Underwriter  may also provide written
information to dealers with whom it has dealer  agreements that relates to sales
incentive campaigns conducted by such dealers for their  representatives as well
as financial  assistance in connection with pre-approved  seminars,  conferences
and advertising.  No such programs or additional compensation will be offered to
the extent they are  prohibited by the laws of any state or any  self-regulatory
agency,  such as the NASD. Dealers to whom substantially the entire sales charge
is reallowed may be deemed to be  underwriters as that term is defined under the
1933 Act.

  The Principal Underwriter may, at its own expense, pay concessions in addition
to those described above to dealers which satisfy certain  criteria  established
from  time to time by the  Principal  Underwriter.  These  conditions  relate to
increasing  sales of shares of the  Keystone  funds over  specified  periods and
certain other factors. Such payments may, depending on the dealer's satisfaction
of the required  conditions,  be periodic and may be up to 0.25% of the value of
shares sold by such dealer.

  The  Principal  Underwriter  also may pay banks and other  financial  services
firms that  facilitate  transactions  in shares of the Fund for their  clients a
transaction  fee up to the level of the payments  made  allowable to dealers for
the sale of such shares as described  above.  The  Glass-Steagall  Act currently
limits the ability of a depository  institution  (such as a commercial bank or a
savings  and loan  association)  to  become an  underwriter  or  distributor  of
securities. In the event the Glass-Steagall Act is deemed to prohibit depository
institutions from accepting  payments under the arrangement  described above, or
should Congress relax current restrictions on depository institutions, the Board
of Trustees will consider what action, if any, is appropriate.
  In  addition,  state  securities  laws on  this  issue  may  differ  from  the
interpretations  of  federal  law  expressed  herein,  and banks  and  financial
institutions may be required to register as dealers pursuant to state law.

DISTRIBUTION PLANS

  As  discussed  above,  the Fund bears some of the costs of selling  its shares
under  Distribution  Plans and other plans  adopted with respect to its Class A,
Class B and Class C shares pursuant to Rule 12b-1 under the 1940 Act.

  The  NASD  currently  limits  the  amount  that a fund  may  pay  annually  in
distribution costs for the sale of its shares and shareholder  service fees. The
NASD limits  annual  expenditures  to 1.00% of the  aggregate  average daily net
asset  value  of a  fund's  shares,  of  which  0.75%  may be used  to pay  such
distribution  costs and 0.25% may be used to pay  shareholder  service fees. The
NASD  also  limits  the  aggregate  amount  that  the  Fund  may  pay  for  such
distribution  costs to 6.25% of gross  share sales  since the  inception  of the
12b-1  Distribution  Plans,  plus  interest  at the  prime  rate plus 1% on such
amounts (less any contingent  deferred sales charges paid by shareholders to the
Principal Underwriter) remaining unpaid from time to time.

  The Principal Underwriter intends, but is not obligated, to continue to pay or
accrue distribution charges incurred in connection with the Class B Distribution
Plans that  exceed  current  annual  payments  permitted  to be  received by the
Principal  Underwriter from the Fund. The Principal  Underwriter intends to seek
full  payment of such  charges  from the Fund  (together  with  annual  interest
thereon at the prime rate plus one  percent)  at such time in the future as, and
to the extent that,  payment  thereof by the Fund would be within the  permitted
limits.

  If the Fund's Independent  Trustees authorize such payments,  the effect would
be to extend the period of time during which the Fund incurs the maximum  amount
of costs allowed by a Distribution  Plan. If a Distribution  Plan is terminated,
the Principal  Underwriter  will ask the  Independent  Trustees to take whatever
action they deem appropriate under the circumstances  with respect to payment of
such amounts.

  In connection  with financing its  distribution  costs,  including  commission
advances  to  dealers  and  others,  the  Principal  Underwriter  has  sold to a
financial  institution  substantially all of its 12b-1 fee collection rights and
contingent  deferred sales charge collection rights in respect of Class B shares
sold during the two-year period commencing  approximately June 1, 1995. The Fund
has  agreed  not to reduce  the rate of payment of 12b-1 fees in respect of such
Class B shares unless it terminates such shares'  Distribution  Plan completely.
If it terminates  such  Distribution  Plan,  the Fund may be subject to possible
adverse distribution consequences.

  Each of the  Distribution  Plans may be  terminated at any time by vote of the
Independent  Trustees or by vote of a majority of the outstanding  voting shares
of the respective class.

   Unreimbursed  distribution  expenses  at October  31, 1994 for Class B shares
were  $230,824  (6.47%  of  Class  B's net  assets).  Unreimbursed  distribution
expenses at October 31,  1994 for Class C shares were  $110,525  (6.95% of Class
C's net assets).

  For the ten month period ended  October 31, 1994,  the Fund paid the Principal
Underwriter $13,778 pursuant to its Class A Distribution Plan. For the ten month
period ended October 31, 1994, the Fund paid the Principal  Underwriter  $26,882
and  $14,984   pursuant  to  its  Class  B  and  Class  C  Distribution   Plans,
respectively.

  Dealers or others may receive  different  levels of compensation  depending on
which class of shares they sell.  Payments  pursuant to a Distribution  Plan are
included in the operating expenses of the class.

HOW TO REDEEM SHARES

  You may redeem Portfolio shares for cash at their net asset value upon written
order to the Fund c/o KIRC, and presentation to the Fund of a properly  endorsed
share certificate (if certificates  have been issued).  Your signature(s) on the
written order and  certificates  must be guaranteed as described below. In order
to redeem  by  telephone,  you must have  completed  the  authorization  in your
account application.

  The  redemption  value equals the net asset value per share and may be more or
less than your  cost  depending  upon  changes  in the value of the  Portfolio's
securities between purchase and redemption.

  If imposed, the deferred sales charge is deducted from the redemption proceeds
otherwise payable to you.

REDEMPTION OF SHARES IN GENERAL
  At various times,  the Fund may be requested to redeem shares for which it has
not yet received good payment. In such a case, the Fund will mail the redemption
proceeds  upon  clearance of the purchase  check which may take up to 15 days or
more.  Any delay may be avoided by  purchasing  shares  either  with a certified
check or by  Federal  Reserve  or bank  wire of funds  or by EFT.  Although  the
mailing of a redemption check or the wiring or EFT of redemption proceeds may be
delayed, the redemption value will be determined and the redemption processed in
the ordinary course of business upon receipt of proper documentation.  In such a
case,  after  the  redemption  and  prior to the  release  of the  proceeds,  no
appreciation or depreciation will occur in the value of the redeemed shares, and
no  interest  will be paid  on the  redemption  proceeds.  If the  payment  of a
redemption  has been delayed,  the check will be mailed or the proceeds wired or
sent EFT promptly after good payment has been collected.

  The Fund  computes  the amount due you at the close of the Exchange at the end
of the day on which it has received all proper  documentation  from you. Payment
of the amount due on redemption,  less any applicable  contingent deferred sales
charge (as described above), will be made within seven days thereafter except as
discussed herein.

  You  may  also  redeem  your  shares  through  broker-dealers.  The  Principal
Underwriter,  acting as agent for the Fund, stands ready to repurchase Portfolio
shares upon orders from  dealers and will  calculate  the net asset value on the
same  terms  as  those  orders  for  the  purchase  of  shares   received   from
broker-dealers  and  described  under  "How  to Buy  Shares."  If the  Principal
Underwriter  has  received  proper  documentation,  it will  pay the  redemption
proceeds,  less any  applicable  deferred  sales  charge,  to the  broker-dealer
placing the order  within  seven days  thereafter.  KDI charges no fees for this
service; your broker-dealer, however, may charge a service fee.

  For your protection,  SIGNATURES ON CERTIFICATES, STOCK POWERS AND ALL WRITTEN
ORDERS OR  AUTHORIZATIONS  MUST BE GUARANTEED BY A U.S. STOCK EXCHANGE MEMBER, A
BANK OR OTHER  PERSONS  ELIGIBLE TO GUARANTEE  SIGNATURES  UNDER THE  SECURITIES
EXCHANGE  ACT OF 1934 AND  KIRC'S  POLICIES.  The Fund or KIRC  may  waive  this
requirement  but  may  also  require  additional  documents  in  certain  cases.
Currently,  the  requirement  for a  signature  guarantee  has  been  waived  on
redemptions  of $50,000 or less when the account  address of record has been the
same for a minimum  period of 30 days.  The Fund and KIRC  reserve  the right to
withdraw this waiver at any time.

  If the Fund receives a redemption  order,  but you have not clearly  indicated
the amount of money or number of shares  involved,  the Fund cannot  execute the
order. In such cases, the Fund will request the missing information from you and
process the order on the day such information is received.

TELEPHONE
  Under ordinary  circumstances,  you may redeem up to $50,000 from your account
by  telephone  by calling  toll free  1-800-343-  2898.  To engage in  telephone
transactions generally, you must complete the appropriate sections of the Fund's
application.

  In order to insure that  instructions  received  by KIRC are genuine  when you
initiate a telephone  transaction,  you will be asked to verify certain criteria
specific to your  account.  At the  conclusion of the  transaction,  you will be
given a transaction number confirming your request,  and written confirmation of
your   transaction  will  be  mailed  the  next  business  day.  Your  telephone
instructions will be recorded.  Redemptions by telephone are allowed only if the
address and bank account of record have been the same for a minimum period of 30
days.

  If the redemption proceeds are less than $2,500, they will be mailed by check.
If they are $2,500 or more,  they will be  mailed,  wired or sent by EFT to your
previously  designated bank account as you direct. If you do not specify how you
wish your redemption proceeds to be sent, they will be mailed by check.

  If you cannot reach the Fund by telephone,  you should  follow the  procedures
for redeeming by mail or through a broker as set forth above.

SMALL ACCOUNTS
  Because of the high cost of maintaining small accounts,  the Fund reserves the
right to redeem your account if its value has fallen below  $1,000,  the current
minimum  investment  level, as a result of your redemptions (but not as a result
of market  action).  You will be  notified  in  writing  and  allowed 60 days to
increase the value of your account to the minimum  investment level. No deferred
sales charges are applied to such redemptions.

REDEMPTIONS IN KIND

  If conditions arise that would make it undesirable for the Fund to pay for all
redemptions  in cash,  the Fund may  authorize  payment for shares to be made in
portfolio securities or other property. The Fund has obligated itself,  however,
under the 1940 Act to redeem for cash all shares presented for redemption by any
one  shareholder  in any 90-day period up to the lesser of $250,000 or 1% of the
Portfolio's net assets at the beginning of such period.  Securities delivered in
payment of  redemptions  would be valued at the same value  assigned  to them in
computing  the net asset value per share and would,  to the extent  permitted by
law, be readily marketable.  Shareholders  receiving such securities would incur
brokerage costs when these securities are sold.

GENERAL
  The Fund  reserves the right at any time to  terminate,  suspend or change the
terms of any redemption  method described in this prospectus,  except redemption
by mail, and to impose fees.

  Except  as  otherwise  noted,   neither  the  Fund,  KIRC  nor  the  Principal
Underwriter  assumes  responsibility  for the  authenticity of any  instructions
received  by any of them  from a  shareholder  in  writing,  over  the  Keystone
Automated  Response Line ("KARL") or by telephone.  KIRC will employ  reasonable
procedures to confirm that  instructions  received over KARL or by telephone are
genuine.  Neither the Fund,  KIRC nor the Principal  Underwriter  will be liable
when  following  instructions  received  over KARL or by  telephone  which  KIRC
reasonably believes to be genuine.

  The Fund may  temporarily  suspend the right to redeem its shares when (1) the
Exchange is closed,  other than  customary  weekend and  holiday  closings;  (2)
trading on the  Exchange is  restricted;  (3) an  emergency  exists and the Fund
cannot dispose of its  investments or fairly  determine  their value; or (4) the
Securities and Exchange Commission so orders.

SHAREHOLDER SERVICES

  Details on all shareholder services may be obtained from KIRC by writing or by
calling toll free 1-800-343-2898.

KEYSTONE AUTOMATED RESPONSE LINE
  The  Keystone  Automated  Response  Line  offers  you  specific  fund  account
information and price and yield  quotations as well as the ability to do account
transactions,  including investments,  exchanges and redemptions. You may access
KARL by dialing toll free 1-800-346- 3858 on any touch-tone telephone,  24 hours
a day, seven days a week.

EXCHANGES
  If you have obtained the  appropriate  prospectus,  you may exchange shares of
the Portfolio  for shares of other  Keystone  America Funds and Keystone  Liquid
Trust ("KLT") as follows:

    Class A shares may be exchanged for Class A shares of other Keystone America
  Funds and Class A shares of KLT;

    Class B shares may be exchanged for the same type of Class B shares of other
  Keystone America Funds and the same type of Class B shares of KLT; and

    Class C shares may be exchanged for Class C shares of other Keystone America
  Funds and Class C shares of KLT.

The  exchange  of Class B shares  and Class C shares  will not be  subject  to a
contingent  deferred  sales charge.  However,  if the shares being  tendered for
exchange are:

  (1) Class A shares  acquired in an NAV Purchase or  otherwise  without a front
end sales charge,

  (2) Class B shares  that have been held for less than 72 months or four years,
as the case may be, or

  (3) Class C shares  that have been held for less than one year,

and are still subject to a deferred sales charge, such charge will carry over to
the shares being acquired in the exchange transaction.

  You may exchange shares by calling toll free 1-800-343-2898 (provided you have
selected  such option on the  application),  by writing KIRC or by calling KARL.
Shares  purchased  by check are eligible  for  exchange  after 15 days.  You may
exchange  your  shares  for  another  Keystone  fund for a $10 fee by calling or
writing to Keystone.  The exchange fee is waived for  individual  investors  who
make an exchange  using KARL. As indicated  above,  if the shares being tendered
for  exchange are still  subject to a deferred  sales  charge,  such charge will
carry over to the shares being  acquired in the exchange  transaction.  The Fund
reserves the right,  after  providing the required  notice to  shareholders,  to
terminate  this  exchange  offer or to change its terms,  including the right to
change the fee for any exchange.

  Orders  to  exchange  a  certain  class of  shares  of the  Portfolio  for the
corresponding class of shares of KLT will be executed by redeeming the shares of
the Portfolio and purchasing the corresponding class of shares of KLT at the net
asset  value of such  shares  next  determined  after  the  proceeds  from  such
redemption  become  available,  which  may  be  up  to  seven  days  after  such
redemption.  In all other cases, orders for exchanges received by the Fund prior
to 4:00  p.m.  eastern  time on any day the  Fund is open for  business  will be
executed  at the  respective  net  asset  values  determined  as of the close of
business that day. Orders for exchanges received after 4:00 p.m. eastern time on
any business day will be executed at the respective net asset values  determined
at the close of the next business day.

  An  excessive  number  of  exchanges  may  be  disadvantageous  to  the  Fund.
Therefore,  the Fund, in addition to its right to reject any exchange,  reserves
the right to terminate the exchange  privilege of any shareholder who makes more
than five  exchanges  of  shares  of the funds in a year or three in a  calendar
quarter.

  An exchange  order must  comply  with the  requirements  for a  redemption  or
repurchase  order and must  specify  the dollar  value or number of shares to be
exchanged. Exchanges are subject to the minimum initial purchase requirements of
the fund being acquired.  An exchange  constitutes a sale for federal income tax
purposes.

  The exchange  privilege  is available  only in states where shares of the fund
being acquired may legally be sold.

KEYSTONE AMERICA MONEY LINE
  Keystone  America  Money Line  eliminates  the delay of mailing a check or the
expense of wiring  funds.  You must  request  the  service on your  application.
Keystone  America  Money Line allows you to  authorize  electronic  transfers of
money to  purchase  shares in any amount  and to redeem up to  $50,000  worth of
shares.  You can use Keystone  America Money Line like an "electronic  check" to
move  money  between  your bank  account  and your  account in the Fund with one
telephone call. You must allow two business days after the call for the transfer
to take place. For money recently invested, you must allow normal check clearing
time before redemption proceeds are sent to your bank.

  You may also arrange for systematic  monthly or quarterly  investments in your
Keystone America account.  Once proper authorization is given, your bank account
will be debited to purchase the specified class of shares in the Portfolio.  You
will receive confirmation from the Principal Underwriter for every transaction.

  To change the amount of a Keystone  America Money Line service or to terminate
such  service  (which  could  take up to 30 days),  you must  write to  Keystone
Investor  Resource Center,  Inc., P.O. Box 2121,  Boston,  Massachusetts  02106-
2121, and include your account number.

RETIREMENT PLANS
  The Fund has  various  pension  and  profit-sharing  plans  available  to you,
including  Individual  Retirement Accounts ("IRAs");  Rollover IRAs;  Simplified
Employee Pension Plans ("SEP's"); Tax Sheltered Annuity Plans ("TSA's");  401(k)
Plans; Keogh Plans; Corporate Profit-Sharing Plans; Money Purchase Pension Plans
and Salary-Reduction  Plans. For details,  including fees and application forms,
call toll free 1-800-247-4075 or write to KIRC

AUTOMATIC WITHDRAWAL PLAN
  Under an Automatic  Withdrawal  Plan,  if your account has a value of at least
$10,000,  you may arrange  for regular  monthly or  quarterly  fixed  withdrawal
payments.  Each  payment  must be at  least  $100 and may be as much as 1.5% per
month or 4.5% per quarter of the total net asset value of the  Portfolio  shares
in your account when the Automatic  Withdrawal Plan is opened.  Fixed withdrawal
payments are not subject to a deferred sales charge.  Excessive  withdrawals may
decrease or deplete the value of your account.  Moreover,  because of the effect
of the applicable  sales charge,  a Class A investor  should not make continuous
purchases  of  the  Portfolio's  shares  while  participating  in  an  Automatic
Withdrawal Plan.

DOLLAR COST AVERAGING
  Through  dollar cost averaging you can invest a fixed dollar amount each month
or each quarter in any Keystone  America Fund. This results in more shares being
purchased  when the selected  fund's net asset value is relatively low and fewer
shares being purchased when the fund's net asset value is relatively high, which
may cause a lower  average  cost per  share  than a less  systematic  investment
approach.

  Prior to participating in dollar cost averaging,  you must have established an
account in a Keystone  America Fund or a money market fund managed or advised by
Keystone.  You should  designate on the  application  the dollar  amount of each
monthly or quarterly  investment (minimum $100) you wish to make and the fund in
which  the  investment  is to be  made.  Thereafter,  on  the  first  day of the
designated  month,  an  amount  equal  to the  specified  monthly  or  quarterly
investment will automatically be redeemed from your initial account and invested
in shares of the designated fund. If you are a Class A investor and paid a sales
charge on your  initial  purchase,  the shares  purchased  will be eligible  for
Rights of Accumulation,  and the sales charge applicable to the purchase will be
determined  accordingly.  In  addition,  the value of shares  purchased  will be
included in the total amount required to fulfill a Letter of Intent.  If a sales
charge was not paid on the initial  purchase,  a sales charge will be imposed at
the time of subsequent  purchases and the value of shares  purchased will become
eligible  for Rights of  Accumulation  and  Letters of Intent.

TWO  DIMENSIONAL INVESTING
  You may elect to have income and capital gains distributions from any class of
Keystone America Fund shares you may own automatically  invested to purchase the
same class of shares of any other  Keystone  America  Fund.  You may select this
service on your application and indicate the Keystone America Fund(s) into which
distributions  are to be  invested.  The  value  of  shares  purchased  will  be
ineligible for Rights of Accumulation and Letters of Intent.

OTHER SERVICES
  Under  certain  circumstances,  you may,  within 30 days  after a  redemption,
reinstate  your account in the same class of shares that you redeemed at current
net asset value.

PERFORMANCE DATA

  From time to time the  Portfolio  may  advertise  "total  return" and "current
yield." ALL DATA IS BASED ON HISTORICAL EARNINGS AND IS NOT INTENDED TO INDICATE
FUTURE  PERFORMANCE.  Total return and current yield are computed separately for
each class of shares of the Fund. Total return refers to the Portfolio's average
annual compounded rates of return over specified periods determined by comparing
the initial amount invested in a particular class to the ending redeemable value
of that amount. The resulting equation assumes reinvestment of all dividends and
distributions and deduction of the maximum sales charge or applicable contingent
deferred  sales charge and all  recurring  charges,  if any,  applicable  to all
shareholder accounts. The exchange fee is not included in the calculation.

  Current yield  quotations  represent  the yield on an investment  for a stated
30-day period computed by dividing net investment income earned per share during
the base period by the maximum  offering  price per share on the last day of the
base period.

  The Fund may  also  include  comparative  performance  data for each  class of
shares in advertising  or marketing the Fund's shares,  such as data from Lipper
Analytical Services,  Inc.,  Morningstar,  Inc., Ibbotson  Associations or other
industry publications.

FUND SHARES

  Generally, the Fund currently issues three classes of shares of the Portfolio,
which  participate  in  dividends  and  distributions  and  have  equal  voting,
liquidation   and  other  rights  except  that  (1)  expenses   related  to  the
distribution  of each  class of  shares  or  other  expenses  that the  Board of
Trustees may designate as class  expenses from time to time, are borne solely by
such class; (2) each class of shares has exclusive voting rights with respect to
its Distribution Plan; (3) each class has different exchange privileges; and (4)
each class generally has a different designation.  When issued and paid for, the
shares will be fully paid and nonassessable by the Fund. Shares may be exchanged
as explained  under  "Shareholder  Services" but will have no other  preference,
conversion,  exchange or preemptive rights. Shares are redeemable,  transferable
and freely assignable as collateral.  The Fund is authorized to issue additional
series (portfolios) and classes of shares.

  Shareholders are entitled to one vote for each full share owned and fractional
votes  for  fractional  shares.  Shares of the Fund vote  together  except  when
required  by law to vote  separately  by class.  The Fund  does not have  annual
meetings.  The Fund will have  special  meetings  from time to time as  required
under its  Declaration  of Trust and under  the 1940  Act.  As  provided  in the
Declaration of Trust of the Fund, shareholders have the right to remove Trustees
by an  affirmative  vote of  two-thirds  of the  outstanding  shares.  A special
meeting  of the  shareholders  will be held when 10% of the  outstanding  shares
request a meeting  for the  purpose  of  removing a Trustee.  As  prescribed  by
Section  16(c) of the 1940 Act,  shareholders  may be eligible  for  shareholder
communication assistance in connection with the special meeting.

  The  Fund's  Declaration  of Trust  provides  that  shareholders  shall not be
subject to any  personal  liability  for the  Fund's  obligations  and  provides
indemnification  from Fund assets for any shareholder held personally liable for
the Fund's obligations.  Disclaimers of such liability are included in each Fund
agreement.  Under  Massachusetts  law,  however,  it is  possible  that  a  Fund
shareholder   might  be  held  personally  liable  for  certain  of  the  Fund's
obligations.

ADDITIONAL INFORMATION

                      ADDITIONAL INVESTMENT INFORMATION
               DESCRIPTIONS OF CERTAIN TYPES OF INVESTMENTS AND
               INVESTMENT TECHNIQUES AVAILABLE TO THE PORTFOLIO

  The Fund may  engage  in the  following  investment  practices  to the  extent
described in the prospectus and the statement of additional information.

CORPORATE BOND RATINGS

  Higher yields are usually available on securities that are lower rated or that
are  unrated.  Bonds  rated  BAA by  Moody's  are  considered  as  medium  grade
obligations  which are neither highly  protected nor poorly secured.  Debt rated
BBB by S&P is regarded as having an adequate  capacity to pay interest and repay
principal,  although  adverse  economic  conditions are more likely to lead to a
weakened  capacity to pay interest and repay principal for debt in this category
than in higher rated  categories.  Lower rated securities are usually defined as
BAA or lower by Moody's or BBB or lower by S&P.  The Fund may  purchase  unrated
securities, which are not necessarily of lower quality than rated securities but
may not be attractive to as many buyers.  Debt rated BB, B, CCC, CC and C by S&P
is regarded,  on balance, as predominantly  speculative with respect to capacity
to pay  interest  and  repay  principal  in  accordance  with  the  terms of the
obligation.  BB indicates  the lowest  degree of  speculation  and C the highest
degree of  speculation.  While  such  debt will  likely  have some  quality  and
protective characteristics, these are outweighed by large uncertainties or major
risk  exposures  to adverse  conditions.  Debt  rated CI by S&P is debt  (income
bonds) on which no interest is being paid. Debt rated D by S&P is in default and
payment of interest  and/or  repayment  of  principal  is in  arrears.  The Fund
intends to invest in D-rated  debt only in cases  where in  Keystone's  judgment
there is a distinct prospect of improvement in the issuer's  financial  position
as a result of the  completion of  reorganization  or otherwise.  Bonds that are
rated CAA by  Moody's  are of poor  standing.  Such  issues may be in default or
there may be present  elements of danger with  respect to principal or interest.
Bonds that are rated CA by Moody's  represent  obligations which are speculative
in a high  degree.  Such  issues  are  often in  default  or have  other  market
shortcomings.  Bonds that are rated C by Moody's  are the lowest  rated class of
bonds, and issues so rated can be regarded as having extremely poor prospects of
ever attaining any real investment standing.

ZERO COUPON BONDS

  A zero coupon  "stripped"  bond  represents  ownership  in  serially  maturing
interest or principal payments on specific underlying notes and bonds, including
coupons  relating to such notes and bonds.  The interest and principal  payments
are direct  obligations  of the issuer.  Coupon zero coupon  bonds of any series
mature  periodically  from the date of issue of such series through the maturity
date of the  securities  related to such  series.  Principal  zero coupon  bonds
mature on the date  specified  therein,  which is the final maturity date of the
related  securities.  Each zero  coupon  bond  entitles  the holder to receive a
single payment at maturity.  There are no periodic  interest  payments on a zero
coupon bond. Zero coupon bonds are offered at discounts from their face amounts.

  In general,  owners of zero coupon bonds have substantially all the rights and
privileges  of  owners  of  the  underlying  coupon   obligations  or  principal
obligations.  Owners of zero  coupon  bonds have the right  upon  default on the
underlying coupon  obligations or principal  obligations to proceed directly and
individually  against  the issuer and are not  required  to act in concert  with
other holders of zero coupon bonds.

  For federal income tax purposes, a purchaser of principal zero coupon bonds or
coupon  zero coupon  bonds  (either  initially  or in the  secondary  market) is
treated  as if the buyer had  purchased  a  corporate  obligation  issued on the
purchase date with an original  issue discount equal to the excess of the amount
payable at maturity over the purchase  price.  The purchaser is required to take
into income each year as ordinary income an allocable  portion of such discounts
determined on a "constant yield" method.  Any such income increases the holder's
tax basis for the zero coupon  bond,  and any gain or loss on a sale of the zero
coupon bonds relative to the holder's basis,  as so adjusted,  is a capital gain
or loss.  If the holder owns both  principal  zero coupon  bonds and coupon zero
bonds  representing  interest  in the same  underlying  issue of  securities,  a
special basis  allocation  rule  (requiring the aggregate  basis to be allocated
among the items sold and retained  based on their  relative fair market value at
the time of sale) may apply to determine  the gain or loss on a sale of any such
zero coupon bonds.

 PAYMENT-IN-KIND SECURITIES

  PIK  securities pay interest in either cash or additional  securities,  at the
issuer's  option,  for a  specified  period.  The  issuer's  option  to  pay  in
additional  securities  typically  ranges  from one to six years  compared to an
average  maturity for all PIK  securities of eleven years.  Call  protection and
sinking fund  features  are  comparable  to those  offered on  traditional  debt
issues.

  PIKs, like zero coupon bonds,  are designed to give the issuer  flexibility in
managing cash flow. Several PIKs are senior debt. In other cases, where PIKs are
subordinated, most senior lenders view them as equity equivalents.

  An  advantage of PIKs for the issuer -- as with zero coupon  securities  -- is
that interest payments are automatically  compounded  (reinvested) at the stated
coupon rate, which is not the case with cash-paying  securities.  However,  PIKs
are  gaining  popularity  over  zeros  since  interest  payments  in  additional
securities can be monetized and are more tangible than accretion of a discount.

  As a group, PIK bonds trade flat (i.e., without accrued interest). Their price
is expected to reflect an amount  representing  accreted interest since the last
payment.  PIKs  generally  trade at higher  yields than  comparable  cash-paying
securities  of the same issuer.  Their premium yield is the result of the lesser
desirability of non-cash interest, the more limited audience for non-cash paying
securities, and the fact that many PIKs have been issued to equity investors who
do not normally own or hold such securities.

  Calculating  the true yield on a PIK security  requires a discounted cash flow
analysis if the  security  (ex  interest)  is trading at a premium or a discount
because  the  realizable  value of  additional  payments is equal to the current
market value of the underlying security, not par.

  Regardless  of  whether  PIK  securities  are  senior or deeply  subordinated,
issuers are highly  motivated to retire them because they are usually their most
costly form of capital.

REPURCHASE  AGREEMENTS

  The  Portfolio  may enter into  repurchase  agreements;  i.e.,  the  Portfolio
purchases a security  subject to the  Portfolio's  obligation  to resell and the
seller's  obligation  to  repurchase  that  security at an agreed upon price and
date,  such  date  usually  being  not more  than  seven  days  from the date of
purchase.  The resale price is based on the  purchase  price plus an agreed upon
market rate of interest  that is unrelated to the coupon rate or maturity of the
purchased security.  A repurchase  agreement imposes an obligation on the seller
to pay the agreed upon price, which obligation is in effect secured by the value
of the underlying  security.  The value of the  underlying  security is at least
equal to the amount of the agreed upon resale price and marked to market  daily.
The  Portfolio  may  enter  into  such  agreements  only  with  respect  to U.S.
government and foreign government  securities,  which may be denominated in U.S.
or foreign currencies.  The Portfolio may enter into such repurchase  agreements
with  foreign  banks and  securities  dealers  approved in advance by the Fund's
Trustees.  Whether a repurchase agreement is the purchase and sale of a security
or a  collateralized  loan has not been  definitively  established.  This  might
become  an  issue in the  event  of the  bankruptcy  of the  other  party to the
transaction.  It does not  presently  appear  possible  to  eliminate  all risks
involved in  repurchase  agreements.  These risks include the  possibility  of a
decline in the market value of the underlying  securities,  as well as delay and
costs to the Portfolio in connection with bankruptcy proceedings.  Therefore, it
is the policy of the  Portfolio to enter into  repurchase  agreements  only with
large, well-capitalized banks that are members of the Federal Reserve System and
with primary dealers in U.S. government securities (as designated by the Federal
Reserve Board) whose  creditworthiness  has been reviewed and found satisfactory
by the Portfolio's adviser. The Portfolio  anticipates that less than 10% of its
net assets will be invested in repurchase agreements maturing in more than seven
days.

CONVERTIBLE SECURITIES

  The Portfolio may invest in convertible  securities.  These securities,  which
include  bonds,   debentures,   corporate  notes,  preferred  stocks  and  other
securities,  are  securities  which the holder can convert  into  common  stock.
Convertible  securities rank senior to common stock in a  corporation's  capital
structure and, therefore, entail less risk than that corporation's common stock.
The value of a convertible  security is a function of its investment  value (its
market  worth  without a conversion  privilege)  and its  conversion  value (its
market worth if  exchanged).  If a convertible  security's  investment  value is
greater  than its  conversion  value,  its  price  primarily  will  reflect  its
investment  value and will tend to vary  inversely  with  interest  rates.  (The
issuer's  creditworthiness  and other  factors  also may affect its value.) If a
convertible  security's  conversion value is greater than its investment  value,
its price will tend to be higher than its conversion  value, and it will tend to
fluctuate directly with the price of the underlying equity security.

WHEN ISSUED AND FORWARD COMMITMENT TRANSACTIONS
  The  Portfolio  may  purchase  newly  issued  securities  on a when issued and
delayed  delivery  basis  and may  purchase  or  sell  securities  on a  forward
commitment  basis.  When  issued or  delayed  delivery  transactions  arise when
securities are purchased 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 to the  Portfolio  at the time of  entering  into the  transaction.  A
forward  commitment  transaction is an agreement by the Portfolio to purchase or
sell securities at a specified future date. When the Portfolio  engages in these
transactions,  the Portfolio relies on the buyer or seller,  as the case may be,
to consummate the sale. Failure to do so may result in the Portfolio missing the
opportunity  to  obtain a price or yield  considered  to be  advantageous.  When
issued and delayed delivery transactions and forward commitment transactions may
be expected to occur a month or more before delivery is due. However, no payment
or delivery is made by the Portfolio until it receives  payment or delivery from
the other party to the transaction. A separate account of liquid assets equal to
the value of purchase  commitments  will be  maintained  until  payment is made.

SHORT SALES
  The Portfolio  may make short sales of  securities  "against the box." A short
sale involves the borrowing of a security,  which must eventually be returned to
the lender.  A short sale is  "against  the box" if, at all times when the short
position is open, the Portfolio owns the securities  sold short or owns an equal
amount  of  securities   convertible  into,  or  exchangeable   without  further
consideration  for,  securities  identical to the securities  sold short.  Short
sales  against  the box are used to defer  recognition  of gains or losses or in
order to receive a portion of the interest  earned by the executing  broker from
the  proceeds of such sale.  The proceeds of a short sale are held by the broker
until the settlement date when the Portfolio  delivers the convertible  security
to close out its short  position.  Although prior to such delivery the Portfolio
will have to pay an amount equal to any dividends  paid on the  securities  sold
short, the Portfolio will receive the dividends from the securities  convertible
into the securities  sold short,  plus a portion of the interest earned from the
proceeds  of the  short  sale.  The  Portfolio  will  not  make  short  sales of
securities subject to outstanding call options written by it. The Portfolio will
segregate the securities sold short or appropriate  convertible  securities in a
special  account with the Fund's  custodian in  connection  with its short sales
"against the box."

LOANS OF SECURITIES
  The Portfolio may lend its securities to broker-dealers or other institutional
borrowers for use in connection with such borrowers' short sales,  arbitrages or
other securities  transactions.  Such loan transactions  afford the Portfolio an
opportunity to continue to earn income on the securities  loaned and at the same
time to earn income on the  collateral  held by it to secure the loan.  Loans of
portfolio  securities  will  be  made  (if at all)  in  strict  conformity  with
applicable  federal  and  state  rules and  regulations.  There may be delays in
recovery of loaned  securities or even a loss of rights in collateral should the
borrower fail financially. Therefore, loans will be made only to firms deemed by
the Portfolio's  adviser to be of good standing and will not be made unless,  in
the  judgment of the  adviser,  the  consideration  to be earned from such loans
justifies  the risk.  The Fund  understands  that it is the current  view of the
staff of the SEC that the Portfolio is permitted to engage in loan  transactions
only if it meets the following  conditions:  (1) the Portfolio must receive 100%
collateral in the form of cash or cash equivalents, e.g., U.S. Treasury bills or
notes, from the borrower; (2) the borrower must increase the collateral whenever
the market value of the  securities  (determined  on a daily basis)  exceeds the
value of the  collateral;  (3) the Portfolio must be able to terminate the loan,
after notice, at any time; (4) the Portfolio must receive reasonable interest on
the loan or a flat fee from the borrower,  as well as amounts  equivalent to any
dividends,  interest or other  distributions  on the  securities  loaned and any
increase in the securities' market values,  which could result from the returned
loaned securities;  (5) the Portfolio may pay only reasonable  custodian fees in
connection  with the loan;  and (6) voting rights on the  securities  loaned may
pass to the borrower;  however,  if a material  event  affecting the  securities
occurs,  the  Portfolio  must be able to terminate  the loan and vote proxies or
enter into an  alternative  arrangement  with the borrower to enable the Fund to
vote proxies.  Excluding items (1) and (2), these procedures may be amended from
time to time, as regulatory policies may permit, by the Fund's Board of Trustees
without shareholder  approval.  Such loans may not exceed 25% of the Portfolio's
total assets.

DERIVATIVES
  The Fund may use derivatives  only in a manner  consistent with its investment
objectives.  Derivatives  are financial  contracts whose value depends on, or is
derived from, the value of an underlying asset,  reference rate or index.  These
assets,  rates, and indices may include bonds, stocks,  mortgages,  commodities,
interest  rates,  currency  exchange  rates,  bond  indices  and stock  indices.
Derivatives  can be used to earn income or protect  against risk,  or both.  For
example,  one party  with  unwanted  risk may agree to pass that risk to another
party who is willing to accept the risk, the second party being  motivated,  for
example,  by the  desire  either to earn  income in the form of a fee or premium
from the first party,  or to reduce its own unwanted  risk by attempting to pass
all or part of that risk to the first party.

  Derivatives  can be used by  investors,  such as the Fund,  to earn income and
enhance  returns,  to hedge or adjust  the risk  profile of the  portfolio,  and
either in place of more traditional  direct investments or to obtain exposure to
otherwise inaccessible markets. The use of derivatives for non- hedging purposes
entails greater risks than if derivatives were used solely for hedging purposes.
The Fund uses  futures  contracts  and related  options as well as forwards  for
hedging  purposes.  Derivatives are a valuable tool,  which, when used properly,
can  provide  significant  benefit  to Fund  shareholders.  With  respect to the
Portfolio,  Keystone does not currently  intend to aggressively use derivatives.
However,  the Portfolio may take positions in those  derivatives that are within
its  investment  policies  if,  in  Keystone's  judgement,  this  represents  an
effective response to current or anticipated  market conditions.  Keystone's use
of  derivatives  is subject to continuous  risk  assessment and control from the
standpoint of the Portfolio's investment objectives and policies.

  Derivatives  may  be  (1)  standardized,   exchange-traded  contracts  or  (2)
customized, privately negotiated contracts.  Exchange-traded derivatives tend to
be more liquid and  subject to less  credit  risk than those that are  privately
negotiated.

  There are four principal types of derivative  instruments-- options,  futures,
forwards and swaps--from which virtually any type of derivative  transaction can
be created. Further information regarding options,  futures, forwards and swaps,
is provided  later in this  section and is provided in the Fund's  statement  of
additional information.

  Debt instruments that incorporate one or more of these building blocks for the
purpose of determining the principal  amount of and/or rate of interest  payable
on the debt  instruments  are often referred to as "structured  securities."  An
example of this type of structured  security is indexed  commercial  paper.  The
term is also used to describe certain  securities  issued in connection with the
restructuring of certain foreign obligations. See "Indexed Commercial Paper" and
"Structured  Securities"  below. The term "derivative" is also sometimes used to
describe  securities  involving  rights to a portion  of the cash  flows from an
underlying  pool of  mortgages  or other  assets from which  payments are passed
through to the owner of, or that  collateralize,  the securities.  See "Mortgage
Related Securities,"  "Collateralized  Mortgage  Obligations,"  "Adjustable Rate
Mortgage  Securities,"  "Stripped Mortgage  Securities,"  "Mortgage Securities -
Special  Considerations,"  and "Other  Asset-Backed  Securities"  and the Fund's
statement of additional information.

  While the judicious use of derivatives by experienced investment managers such
as Keystone can be beneficial,  derivatives  also involve risks  different from,
and, in certain  cases,  greater than, the risks  presented by more  traditional
investments.  Following is a general  discussion  of important  risk factors and
issues concerning the use of derivatives that investors should understand before
investing in the Fund.

* Market Risk -- This is the general risk attendant to all investments  that the
  value of a particular  investment  will  decline or otherwise  change in a way
  detrimental to the Portfolio's interest.

* Management Risk -- Derivative products are highly specialized instruments that
  require   investment   techniques  and  risk  analyses  different  from  those
  associated  with  stocks  and  bonds.  The  use of a  derivative  requires  an
  understanding  not  only  of  the  underlying  instrument,  but  also  of  the
  derivative  itself,  without the benefit of observing the  performance  of the
  derivative under all possible market  conditions.  In particular,  the use and
  complexity of  derivatives  require the  maintenance  of adequate  controls to
  monitor the  transactions  entered into, the ability to assess the risk that a
  derivative adds to the Portfolio and the ability to forecast  price,  interest
  rate or currency exchange rate movements correctly.

* Credit Risk -- This is the risk that a loss may be sustained by the  Portfolio
  as a result of the failure of another party to a derivative  (usually referred
  to as a "counterparty")  to comply with the terms of the derivative  contract.
  The credit risk for  exchange-traded  derivatives  is generally  less than for
  privately  negotiated  derivatives,  since the  clearing  house,  which is the
  issuer  or  counterparty  to  each  exchange-traded  derivative,   provides  a
  guarantee of  performance.  This  guarantee  is  supported by a daily  payment
  system (i.e., margin requirements)  operated by the clearing house in order to
  reduce overall credit risk. For privately negotiated derivatives,  there is no
  similar  clearing  agency  guarantee.   Therefore,   the  Fund  considers  the
  creditworthiness of each counterparty to a privately negotiated  derivative in
  evaluating potential credit risk.

* Liquidity  Risk --  Liquidity  risk exists  when a  particular  instrument  is
  difficult to purchase or sell.  If a derivative  transaction  is  particularly
  large  or if the  relevant  market  is  illiquid  (as is the  case  with  many
  privately  negotiated  derivatives),  it may not be  possible  to  initiate  a
  transaction or liquidate a position at an advantageous price.

* Leverage Risk -- Since many  derivatives  have a leverage  component,  adverse
  changes  in the  value or level of the  underlying  asset,  rate or index  can
  result  in a loss  substantially  greater  than  the  amount  invested  in the
  derivative itself. In the case of swaps, the risk of loss generally is related
  to a notional principal amount,  even if the parties have not made any initial
  investment.  Certain  derivatives  have  the  potential  for  unlimited  loss,
  regardless of the size of the initial investment.

* Other Risks -- Other risks in using derivatives include the risk of mispricing
  or improper valuation and the inability of derivatives to correlate  perfectly
  with underlying  assets,  rates and indices.  Many derivatives,  in particular
  privately negotiated  derivatives,  are complex and often valued subjectively.
  Improper  valuations  can result in  increased  cash payment  requirements  to
  counterparties or a loss of value to the Portfolio.  Derivatives do not always
  perfectly or even highly correlate or track the value of the assets,  rates or
  indices they are designed to closely track. Consequently,  the Portfolio's use
  of derivatives may not always be an effective means of, and sometimes could be
  counterproductive to, furthering the Portfolio's investment objectives.

OPTIONS TRANSACTIONS
  WRITING COVERED OPTIONS. The Portfolio may write (i.e., sell) covered call and
put options.  No more than 25% of the  Portfolio's net assets will be subject to
covered  options.  By writing a call option,  the  Portfolio  becomes  obligated
during the term of the option to deliver the  securities  underlying  the option
upon  payment of the  exercise  price.  By writing a put option,  the  Portfolio
becomes  obligated  during the term of the  option to  purchase  the  securities
underlying the option at the exercise price if the option is exercised.

  The Portfolio may only write "covered" options. This means that so long as the
Portfolio is obligated as the writer of a call option it will own the underlying
securities  subject  to the  option  or,  in the  case of call  options  on U.S.
Treasury bills,  the Portfolio  might own  substantially  similar U.S.  Treasury
bills.  If the Portfolio has written  options against all of its securities that
are  eligible  for  writing  options,  the  Portfolio  may be  unable  to  write
additional options unless it sells a portion of its portfolio holdings to obtain
new securities against which it can write options. If this were to occur, higher
portfolio turnover and, correspondingly, greater brokerage commissions and other
transaction costs may result. The Portfolio does not expect,  however, that this
will occur.

  The  Portfolio  will be considered  "covered"  with respect to a put option it
writes  if,  so long as it is  obligated  as the  writer of the put  option,  it
deposits and maintains liquid assets having a value equal to or greater than the
exercise price of the option with the Fund's custodian in a segregated account.
  The principal  reason for writing call or put options is to obtain,  through a
receipt of  premiums,  a greater  current  return  than would be realized on the
underlying  securities  alone.  The Portfolio  receives a premium from writing a
call or put option which it retains  whether or not the option is exercised.  By
writing a call option,  the  Portfolio  might lose the potential for gain on the
underlying  security while the option is open, and by writing a put option,  the
Portfolio  might become  obligated to purchase the underlying  security for more
than its current market price upon exercise.

  PURCHASING OPTIONS. The Portfolio may purchase call and put options.

  The  Portfolio  would  normally  purchase  call  options  to hedge  against an
increase in the market value of the  Portfolio's  securities.  The purchase of a
call option would  entitle the  Portfolio,  in return for the premium  paid,  to
purchase specified securities at a specified price, upon exercise of the option,
during the option  period.  The Portfolio  would  ordinarily  realize a gain if,
during the option period,  the value of such  securities  exceeds the sum of the
exercise price, the premium paid and transaction costs;  otherwise the Portfolio
would realize a loss on the purchase of the call option.

  The Portfolio may purchase put or call options,  including  purchasing  put or
call  options  for the  purpose of  offsetting  previously  written  put or call
options  of the same  series.  If the  Portfolio  is  unable to effect a closing
purchase  transaction  with  respect to  covered  options  it has  written,  the
Portfolio will not be able to sell the underlying  securities  until the options
expire or are exercised.

  The Portfolio  would normally  purchase put options to hedge against a decline
in the market  value of  securities  in its  portfolio  (protective  puts).  The
Portfolio will not engage in such transactions for speculation.  The purchase of
a put option would entitle the  Portfolio,  in exchange for the premium paid, to
sell  specified  securities at a specified  price,  upon exercise of the option,
during the option  period.  Gains and losses on the purchase of  protective  put
options  would  tend to be  offset  by  countervailing  changes  in the value of
underlying portfolio  securities.  The Portfolio would ordinarily realize a gain
if, during the option period,  the value of the underlying  securities  declined
below the  exercise  price  sufficiently  to cover the premium  and  transaction
costs;  otherwise the Portfolio  would realize a loss on the purchase of the put
option.

  The Portfolio may purchase put and call options on securities  indices for the
same purposes as the purchase of options on securities.  Currently, only options
on  stock  indices  are  traded  and  only on  national  exchanges.  Options  on
securities  indices  are  similar  to  options on  securities,  except  that the
exercise of securities index options requires cash payments and does not involve
the actual purchase or sale of securities. In addition, securities index options
are designed to reflect price  fluctuations  in a group of securities or segment
of the securities  market rather than price  fluctuations in a single  security.
The  Portfolio's  purchases of  securities  index options is subject to the risk
that the value of its  portfolio  securities  may not change as much as an index
because  the  Portfolio's   investments   generally  cannot  match  exactly  the
composition of an index.

  An option position may be closed out only in a secondary  market for an option
of the same  series.  Although the  Portfolio  will  generally  write only those
options for which there appears to be an active  secondary  market,  there is no
assurance that a liquid secondary market will exist for any particular option at
any particular time, and for some options no secondary market may exist. In such
event it might not be possible to effect a closing  transaction  in a particular
option.

  Options on some securities are relatively new, and it is impossible to predict
the amount of trading interest that will exist in such options.  There can be no
assurance  that viable  markets will  develop or  continue.  The failure of such
markets  to develop  or  continue  could  significantly  impair the  Portfolio's
ability to use such options to achieve its investment objectives.

OPTIONS TRADING MARKETS
  Options in which the  Portfolio  will trade are  generally  listed on national
securities  exchanges.  Exchanges  on which such  options  currently  are traded
include the Chicago Board Options Exchange and the New York,  American,  Pacific
and Philadelphia  Stock Exchanges.  Options on some securities may not be listed
on any exchange but traded in the over-the-counter market. Options traded in the
over-the-counter  market involve the  additional  risk that  securities  dealers
participating in such  transactions  could fail to meet their obligations to the
Portfolio.  The use of  options  traded in the  over-the-counter  market  may be
subject to limitations imposed by certain state securities authorities.

  The staff of the  Securities  and Exchange  Commission  ("SEC") is of the view
that the premiums that the Portfolio  pays for the purchase of unlisted  options
and the  value of  securities  used to cover  unlisted  options  written  by the
Portfolio are considered to be invested in illiquid securities or assets for the
purpose  of  calculating  whether  the  Portfolio  is  in  compliance  with  its
fundamental investment restrictions relating to illiquid securities.

FUTURES TRANSACTIONS
  The  Portfolio  may enter into futures  contracts  for the purchase or sale of
securities or currencies or futures  contracts  based on securities  indices and
may write options on such  contracts.  The Portfolio  intends to enter into such
contracts and related options for hedging purposes. The Portfolio may enter into
other types of futures  contracts  that may become  available  and relate to the
securities held by the Portfolio.  A futures  contract is an agreement to buy or
sell  securities or currencies at a specified  price during a designated  month.
The Portfolio does not make payment or deliver  securities  upon entering into a
futures contract.  Instead, it puts down a margin deposit,  which is adjusted to
reflect  changes  in the value of the  contract  and which  continues  until the
contract is terminated.

  The Portfolio may sell or purchase futures contracts.  When a futures contract
is sold by the  Portfolio,  the value of the contract will tend to rise when the
value of the underlying  securities or currencies  declines and to fall when the
value of such securities or currencies increases. Thus, the Portfolio would sell
futures  contracts  in order to offset a  possible  decline  in the value of its
securities or currencies. If a futures contract were purchased by the Portfolio,
the value of the  contract  would tend to rise when the value of the  underlying
securities or currencies increased and to fall when the value of such securities
or currencies  declined.  The Portfolio intends to purchase futures contracts in
order to fix what is believed by its  advisers to be a favorable  price and rate
of return for securities or favorable exchange rate for currencies the Portfolio
intends to purchase.

  The  Portfolio  also may  purchase  put and call  options  on  securities  and
currency futures contracts for hedging  purposes.  A put option purchased by the
Portfolio  would  give it the  right to  assume a  position  as the  seller of a
futures  contract.  A call option  purchased by the Portfolio  would give it the
right to assume a position as the purchaser of a futures contract.  The purchase
of an option on a futures contract  requires the Portfolio to pay a premium.  In
exchange  for the  premium,  the  Portfolio  becomes  entitled to  exercise  the
benefits, if any, provided by the futures contract,  but is not required to take
any action under the  contract.  If the option  cannot be  exercised  profitably
before it  expires,  the  Portfolio's  loss will be limited to the amount of the
premium and any transaction costs.

  In addition,  the  Portfolio  may write (sell) put and call options on futures
contracts  for  hedging  purposes.  The  writing  of a put  option  on a futures
contract  generates  a premium,  which may  partially  offset an increase in the
price of  securities  that the  Portfolio  intends  to  purchase.  However,  the
Portfolio  becomes  obligated to purchase a futures  contract,  which may have a
value lower than the exercise price. Conversely, the writing of a call option on
a futures  contract  generates a premium which may partially offset a decline in
the value of the  Portfolio's  assets.  By writing a call option,  the Portfolio
becomes obligated, in exchange for the premium, to sell a futures contract which
may have a value higher than the exercise price.

  The Portfolio may enter into closing  purchase and sale  transactions in order
to  terminate  a  futures  contract  and may sell put and call  options  for the
purpose of closing out its options positions.  The Portfolio's  ability to enter
into closing transactions depends on the development and maintenance of a liquid
secondary  market.  There is no assurance  that a liquid  secondary  market will
exist for any particular contract or at any particular time. As a result,  there
can be no assurance  that the Portfolio will be able to enter into an offsetting
transaction  with respect to a particular  contract at a particular time. If the
Portfolio is not able to enter into an  offsetting  transaction,  the  Portfolio
will continue to be required to maintain the margin deposits on the contract and
to complete the contract according to its terms, in which case it would continue
to bear market risk on the transaction.

  Although futures and options transactions are intended to enable the Portfolio
to manage market, interest rate or exchange rate risk,  unanticipated changes in
interest  rates,  exchange  rates  or  market  prices  could  result  in  poorer
performance  than if it had not  entered  into these  transactions.  Even if the
Portfolio's  adviser correctly  predicts interest or exchange rate movements,  a
hedge could be unsuccessful  if changes in the value of the Portfolio's  futures
position did not  correspond  to changes in the value of its  investments.  This
lack of correlation between the Portfolio's futures and securities or currencies
positions  may be caused by  differences  between the futures and  securities or
currencies  markets or by  differences  between  the  securities  or  currencies
underlying  the  Portfolio's  futures  position and the securities or currencies
held by or to be purchased for the  Portfolio.  In addition,  futures  contracts
transactions involve the remote risk that a party participating in a transaction
will not be able to fulfill  its  obligations  and the amount of the  obligation
will exceed the ability of the  clearing  broker to  satisfy.  The adviser  will
attempt to minimize these risks through careful  selection and monitoring of the
Portfolio's futures and options positions.

  The Portfolio does not intend to use futures  transactions  for speculation or
leverage. The Portfolio may not purchase or sell futures contracts or options on
futures,  except for  closing  purchase  or sale  transactions,  if  immediately
thereafter the sum of margin deposits on the Portfolio's outstanding futures and
options  positions  and premiums paid for  outstanding  options on futures would
exceed 5% of the market value of the Portfolio's total assets. The Fund will not
change these policies of the Portfolio  without  supplementing  the  information
contained in its  prospectus  and statement of additional  information.

FOREIGN CURRENCY TRANSACTIONS
  The Portfolio may invest in securities of foreign issuers.  When the Portfolio
invests  in foreign  securities  they  usually  will be  denominated  in foreign
currencies,  and the Portfolio temporarily may hold funds in foreign currencies.
Thus,  the value of  Portfolio  shares  will be  affected by changes in exchange
rates.

  As one way of managing  exchange  rate risk,  in  addition  to  entering  into
currency  futures  contracts,  the  Portfolio  may enter into  forward  currency
exchange  contracts  (agreements  to purchase or sell  currencies at a specified
price and date).  The exchange rate for the transaction  (the amount of currency
the Portfolio  will deliver and receive when the contract is completed) is fixed
when the Portfolio  enters into the contract.  The Portfolio  usually will enter
into these  contracts  to stabilize  the U.S.  dollar value of a security it has
agreed to buy or sell. The Portfolio intends to use these contracts to hedge the
U.S.  dollar value of a security it already owns,  particularly if the Portfolio
expects a decrease in the value of the currency in which the foreign security is
denominated.  Although the Portfolio  will attempt to benefit from using forward
contracts,  the success of its  hedging  strategy  will depend on its  adviser's
ability  to  predict  accurately  the  future  exchange  rates  between  foreign
currencies  and the  U.S.  dollar.  The  value  of the  Portfolio's  investments
denominated in foreign  currencies will depend on the relative strength of those
currencies and the U.S. dollar,  and the Portfolio may be affected  favorably or
unfavorably  by changes in the exchange  rates or exchange  control  regulations
between foreign currencies and the dollar.  Changes in foreign currency exchange
rates also may affect the value of  dividends  and  interest  earned,  gains and
losses  realized on the sale of securities and net investment  income and gains,
if any, to be distributed to  shareholders  by the Portfolio.  The Portfolio may
also purchase and sell options related to foreign  currencies in connection with
hedging strategies.

INTEREST RATE  TRANSACTIONS  (SWAPS,  CAPS AND FLOORS).  If the Portfolio enters
into  interest  rate  swap,  cap or  floor  transactions,  it  expects  to do so
primarily for hedging purposes,  which may include preserving a return or spread
on a particular  investment or portion of its portfolio or protecting against an
increase in the price of securities  the Portfolio  anticipates  purchasing at a
later date. The Portfolio does not currently intend to use these transactions in
a speculative manner.

  Interest rate swaps  involve the exchange by the Portfolio  with another party
of their respective commitments to pay or receive interest (e.g., an exchange of
floating rate payments for fixed rate  payments).  Interest rate caps and floors
are similar to options in that the  purchase  of an  interest  rate cap or floor
entitles the  purchaser,  to the extent that a specified  index  exceeds (in the
case of a cap) or falls below (in the case of a floor) a predetermined  interest
rate,  to receive  payments  of  interest on a  contractually-  based  principal
("notional")  amount from the party selling the interest rate cap or floor.  The
Portfolio  may enter  into  interest  rate  swaps,  caps and floors on either an
asset-based or liability-based  basis,  depending upon whether it is hedging its
assets or liabilities,  and will usually enter into interest rate swaps on a net
basis  (i.e.,  the two  payment  streams  are  netted  out,  with the  Portfolio
receiving  or  paying,  as the  case  may be,  only  the net  amount  of the two
payments).

  The swap market has grown  substantially in recent years,  with a large number
of banks  and  investment  banking  firms  acting  as  principals  and as agents
utilizing  standardized  swap  documentation.  As a result,  the swap market has
become more established and relatively  liquid.  Caps and floors are less liquid
than swaps.  These transactions also involve the delivery of securities or other
underlying assets and principal.  Accordingly, the risk of loss to the Portfolio
from  interest  rate  transactions  is  limited  to the net  amount of  interest
payments  that  the  Portfolio  is  contractually  obligated  to  make.

INDEXED COMMERCIAL PAPER. Indexed commercial paper may have its principal linked
to changes in foreign  currency  exchange rates whereby its principal  amount is
adjusted  upwards  or  downwards  (but not below  zero) at  maturity  to reflect
changes  in the  referenced  exchange  rate.  If  permitted  by  its  investment
policies, the Portfolio will purchase such commercial paper with the currency in
which it is denominated  and, at maturity,  will receive  interest and principal
payments  thereon in that currency,  but the amount of principal  payable by the
issuer at  maturity  will  change in  proportion  to the  change (if any) in the
exchange  rate  between  the two  specified  currencies  between  the  date  the
instrument is issued and the date the instrument matures.  While such commercial
paper entails the risk of loss of principal,  the potential for realizing  gains
as a result of changes in foreign currency  exchange rates enables the Portfolio
to hedge  (or  cross-  hedge)  against  a decline  in the U.S.  dollar  value of
investments  denominated  in foreign  currencies  while  providing an attractive
money market rate of return.

MORTGAGE-RELATED  SECURITIES.  The  mortgage-related  securities  in  which  the
Portfolio may invest typically are securities representing interests in pools of
mortgage loans made to home owners. Mortgage-related securities bear interest at
either a fixed rate or an  adjustable  rate  determined by reference to an index
rate.  The mortgage loan pools may be assembled  for sale to investors  (such as
the  Portfolio)  by  governmental  or  private  organizations.  Mortgage-related
securities issued by the Government National Mortgage  Association  ("GNMA") are
backed by the full  faith and  credit of the U.S.  government;  those  issued by
Federal  National  Mortgage  Associated  ("FNMA") and Federal Home Loan Mortgage
Corporation ("FHLMC") are not so backed.

  Securities   representing  interests  in  pools  created  by  private  issuers
generally offer a higher rate of interest than securities representing interests
in pools created by governmental issuers because there are no direct or indirect
governmental  guarantees of the underlying mortgage payments.  However,  private
issuers sometimes obtain committed loan facilities,  lines of credit, letters of
credit,  surety  bonds or other forms of  liquidity  and credit  enhancement  to
support  the timely  payment of interest  and  principal  with  respect to their
securities  if the  borrowers  on the  underlying  mortgages  fail to make their
mortgage payments. The ratings of such non-governmental securities are generally
dependent upon the ratings of the providers of such liquidity and credit support
and  would  be  adversely  affected  if the  rating  of  such an  enhancer  were
downgraded.  The Portfolio may buy  mortgage-related  securities  without credit
enhancement  if  the  securities  meet  the  Portfolio's  investment  standards.
Although the market for  mortgage-related  securities  is becoming  increasingly
liquid, those of certain private organizations may not be readily marketable.

  One type of mortgage-related  security is of the "pass-through"  variety.  The
holder of a pass-through  security is considered to own an undivided  beneficial
interest in the underlying  pool of mortgage loans and receives a pro rata share
of the monthly  payments made by the borrowers on their mortgage  loans,  net of
any fees paid to the  issuer or  guarantor  of the  securities.  Prepayments  of
mortgages resulting from the sale,  refinancing or foreclosure of the underlying
properties   are  also  paid  to  the   holders   of  these   securities.   Some
mortgage-related  securities, such as securities issued by GNMA, are referred to
as  "modified  pass-through"  securities.  The holders of these  securities  are
entitled  to the full and  timely  payment of  principal  and  interest,  net of
certain fees, regardless of whether payments are actually made on the underlying
mortgages.   Another  form  of  mortgage-related  security  is  a  "pay-through"
security, which is a debt obligation of the issuer secured by a pool of mortgage
loans  pledged as collateral  that is legally  required to be paid by the issuer
regardless of whether  payments are actually made on the  underlying  mortgages.

COLLATERALIZED MORTGAGE OBLIGATIONS.  ("CMOs") are the predominant type of "pay-
through"  mortgage-related  security.  CMOs are  designed  to reduce the risk of
prepayment for investors by issuing multiple classes of securities,  each having
different  maturities,  interest  rates  and  payment  schedules,  and  with the
principal and interest on the underlying  mortgages  allocated among the several
classes in various ways. The collateral  securing the CMOs may consist of a pool
of  mortgages,  but may also consist of  mortgage-backed  bonds or  pass-through
securities. CMOs may be issued by a U.S. government instrumentality or agency or
by a private issuer.  Although payment of the principal of, and interest on, the
underlying  collateral securing privately issued CMOs may be guaranteed by GNMA,
FNMA or FHLMC, these CMOs represent obligations solely of the private issuer and
are not insured or  guaranteed  by GNMA,  FNMA,  FHLMC,  any other  governmental
agency or any other  person or  entity.

INVERSE  FLOATING  RATE  COLLATERALIZED  MORTGAGE  OBLIGATIONS.  In  addition to
investing in fixed rate and adjustable  rate CMOs, the Portfolio may also invest
in CMOs with rates that move inversely to market rates ("inverse floaters").

  An  inverse  floater  bears an  interest  rate  that  resets  in the  opposite
direction of the change in a specified  interest rate index.  As market interest
rates rise, the interest rate on the inverse  floater goes down, and vice versa.
Inverse  floaters tend to exhibit greater price volatility than fixed-rate bonds
of similar  maturity and credit quality.  The interest rates on inverse floaters
may be significantly  reduced,  even to zero, if interest rates rise.  Moreover,
the secondary market for inverse floaters may be limited in rising interest rate
environments.

ADJUSTABLE RATE MORTGAGE SECURITIES.  Another type of mortgage-related security,
known as adjustable-rate  mortgage securities ("ARMS"), bears interest at a rate
determined by reference to a predetermined interest rate or index. There are two
main  categories  of rates or  indices:  (1)  rates  based on the  yield on U.S.
Treasury  securities and (2) indices derived from a calculated measure such as a
cost of funds  index or a moving  average  of  mortgage  rates.  Some  rates and
indices closely mirror changes in market interest rate levels, while others tend
to lag changes in market rate levels and tend to be somewhat less volatile.

  ARMS may be secured by adjustable-rate mortgages or fixed-rate mortgages. ARMS
secured by fixed-rate mortgages generally have lifetime caps on the coupon rates
of the  securities.  To the extent that general  interest rates increase  faster
than the  interest  rates on the ARMS,  these ARMS will  decline  in value.  The
adjustable-rate  mortgages that secure ARMS will frequently have caps that limit
the  maximum  amount by which the  interest  rate or the monthly  principal  and
interest  payments on the mortgages may increase.  These payment caps can result
in negative  amortization  (i.e.,  an  increase  in the balance of the  mortgage
loan). Furthermore, since many adjustable-rate mortgages only reset on an annual
basis,  the  values of ARMS tend to  fluctuate  to the  extent  that  changes in
prevailing  interest rates are not  immediately  reflected in the interest rates
payable  on  the  underlying   adjustable-rate   mortgages.

STRIPPED MORTGAGE SECURITIES.  Stripped mortgage-related securities ("SMRS") are
mortgage-related  securities  that are  usually  structured  with two classes of
securities  collateralized by a pool of mortgages or a pool of  mortgaged-backed
bonds  or  pass-through   securities,   with  each  class  receiving   different
proportions of the principal and interest payments from the underlying assets. A
common type of SMRS has one class of interest-only  securities ("IOs") receiving
all of the interest payments from the underlying  assets,  while the other class
of securities,  principal-only securities ("POs"), receives all of the principal
payments from the  underlying  assets.  IOs and POs are  extremely  sensitive to
interest  rate changes and are more volatile  than  mortgage-related  securities
that are not stripped. IOs tend to decrease in value as interest rates decrease,
while POs generally increase in value as interest rates decrease. If prepayments
of the underlying mortgages are greater than anticipated, the amount of interest
earned on the overall pool will decrease due to the decreasing principal balance
of the assets. Changes in the values of IOs and POs can be substantial and occur
quickly,  such as  occurred in the first half of 1994 when the value of many POs
dropped  precipitously  due to increase in interest  rates.  For this reason the
Portfolio does not rely on IOs and POs as the principal  means of furthering its
investment objective.

MORTGAGE-RELATED   SECURITIES   --   SPECIAL   CONSIDERATIONS.   The   value  of
mortgage-related   securities  is  affected  by  a  number  of  factors.  Unlike
traditional debt securities,  which have fixed maturity dates,  mortgage-related
securities  may be paid earlier than  expected as a result of  prepayment of the
underlying mortgages.  If property owners make unscheduled  prepayments of their
mortgage  loans,  these  prepayments  will  result in the early  payment  of the
applicable  mortgage-related  securities.  In that  event the  Portfolio  may be
unable to invest the  proceeds  from the early  payment of the  mortgage-related
securities   in  an   investment   that   provides   as  high  a  yield  as  the
mortgage-related  securities.   Consequently,   early  payment  associated  with
mortgage-related  securities causes these securities to experience significantly
greater price and yield volatility than experienced by traditional  fixed-income
securities.  The occurrence of mortgage  prepayments is affected by the level of
general  interest  rates,  general  economic  conditions  and other  social  and
demographic  factors.  During  periods of falling  interest  rates,  the rate of
mortgage prepayments tends to increase,  thereby tending to decrease the life of
mortgage-related  securities.  During periods of rising interest rates, the rate
of mortgage prepayments usually decreases,  thereby tending to increase the life
of mortgage-related  securities.  If the life of a mortgage-related  security is
inaccurately  predicted,  the  Portfolio  may not be able to realize the rate of
return it expected.

  As with  fixed-income  securities  generally,  the  value of  mortgage-related
securities can also be adversely affected by increases in general interest rates
relative  to the yield  provided  by such  securities.  Such  adverse  effect is
especially possible with fixed-rate mortgage securities.  If the yield available
on other investments rises above the yield of the fixed-rate mortgage securities
as a result of general  increases  in  interest  rate  levels,  the value of the
mortgage-related  securities will decline. Although the negative effect could be
lessened  if the  mortgage-related  securities  were  to be paid  earlier  (thus
permitting  the  Portfolio to reinvest the  prepayment  proceeds in  investments
yielding the higher  current  interest  rate),  as  described  above the rate of
mortgage   prepayments  and  earlier  payment  of  mortgage-related   securities
generally tends to decline during a period of rising interest rates.

  Although  the value of ARMS may not be  affected by rising  interest  rates as
much as the  value of  fixed-rate  mortgage  securities  is  affected  by rising
interest  rates,  ARMS may still decline in value as a result of rising interest
rates.  Although,  as described  above, the yield on ARMS varies with changes in
the applicable interest rate or index, there is often a lag between increases in
general  interest  rates  and  increases  in the  yield on ARMS as a  result  of
relatively  infrequent  interest rate reset dates. In addition,  adjustable-rate
mortgages  and ARMS often  have  interest  rate or  payment  caps that limit the
ability of the  adjustable-rate  mortgages or ARMS to fully reflect increases in
the  general  level  of  interest  rates.

OTHER  ASSET-BACKED  SECURITIES.
  The securitization techniques used to develop mortgage-related  securities are
being  applied to a broad range of financial  assets.  Through the use of trusts
and special purpose corporations,  various types of assets, including automobile
loans and leases, credit card receivables,  home equity loans,  equipment leases
and trade  receivables,  are being  securitized  in  structures  similar  to the
structures used in mortgage  securitizations.  These asset-backed securities are
subject to risks  associated  with changes in interest  rates and  prepayment of
underlying  obligations  similar to the risks of investment in  mortgage-related
securities discussed above.

  Each type of asset-backed  security also entails unique risks depending on the
type of assets involved and the legal  structure used. For example,  credit card
receivables  are generally  unsecured  obligations of the credit card holder and
the debtors  are  entitled  to the  protection  of a number of state and federal
consumer  credit  laws,  many of which  give such  debtors  the right to set off
certain  amounts  owed on the credit  cards,  thereby  reducing the balance due.
There  have also been  proposals  to cap the  interest  rate that a credit  card
issuer may charge. In some transactions,  the value of the asset-backed security
is dependent on the  performance  of a third party acting as credit  enhancer or
servicer.  Furthermore,  in some  transactions  (such  as  those  involving  the
securitization of vehicle loans or leases) it may be administratively burdensome
to perfect the interest of the security issuer in the underlying  collateral and
the underlying collateral may become damaged or stolen.

VARIABLE, FLOATING AND LEVERAGED INVERSE FLOATING RATE INSTRUMENTS. Fixed-income
securities may have fixed, variable or floating rates of interest.  Variable and
floating rate  securities pay interest at rates that are adjusted  periodically,
according  to a  specified  formula.  A  "variable"  interest  rate  adjusts  at
predetermined  intervals (e.g.,  daily,  weekly or monthly),  while a "floating"
interest  rate  adjusts  whenever a specified  benchmark  rate (such as the bank
prime lending rate) changes.

  If  permitted  by  its  investment  policies,  the  Portfolio  may  invest  in
fixed-income securities that pay interest at a coupon rate equal to a base rate,
plus  additional  interest for a certain  period of time if short-term  interest
rates  rise  above  a  predetermined  level  or  "cap."  The  amount  of such an
additional  interest payment  typically is calculated under a formula based on a
short-term interest rate index multiplied by a designated factor.

  An inverse  floater may be  considered  to be leveraged to the extent that its
interest rate varies by a magnitude  that exceeds the magnitude of the change in
the index rate of interest.  The higher  degree of leverage  inherent in inverse
floaters is  associated  with greater  volatility  in market  value.

STRUCTURED  SECURITIES.  Structured  securities  represent interests in entities
organized and operated  solely for the purpose of  restructuring  the investment
characteristics of sovereign debt obligations or foreign government  securities.
This type of  restructuring  involves the deposit with or purchase by an entity,
such as a corporation  or trust,  of specified  instruments  (such as commercial
bank  loans or Brady  Bonds)  and the  issuance  by that  entity  of one or more
classes of structured  securities  backed by, or representing  interests in, the
underlying  instruments.  The cash  flow on the  underlying  instruments  may be
apportioned  among the newly issued  structured  securities to create securities
with different investment  characteristics  such as varying maturities,  payment
priorities  and interest  rate  provisions,  and the extent of the payments made
with  respect to  structured  securities  is dependent on the extent of the cash
flow on the underlying  instruments.  Because  structured  securities  typically
involve no credit enhancement, their credit risk generally will be equivalent to
that of the underlying  instruments.  Structured securities of a given class may
be either  subordinated  or  unsubordinated  to the right of  payment of another
class.  Subordinated  structured  securities  typically  have higher  yields and
present greater risks than unsubordinated structured securities.

BRADY BONDS. Brady Bonds are created through the exchange of existing commercial
bank loans to foreign  entities  for new  obligations  in  connection  with debt
restructurings under a plan introduced by former U.S. Secretary of the Treasury,
Nicholas  F.  Brady (the  "Brady  Plan").  Brady  Bonds  have been  issued  only
recently,  and,  accordingly,  do not have a long payment  history.  They may be
collateralized or  uncollateralized  and issued in various currencies  (although
most  are  U.S.   dollar-denominated)  and  they  are  actively  traded  in  the
over-the-counter secondary market.

  U.S.  dollar-denominated,  collateralized Brady Bonds, which may be fixed-rate
par bonds or floating rate discount bonds, are generally  collateralized in full
as to principal due at maturity by U.S.  Treasury zero coupon  obligations  that
have the same  maturity  as the Brady  Bonds.  Interest  payments on these Brady
Bonds generally are  collateralized  by cash or securities in an amount that, in
the case of fixed rate bonds, is equal to at least one year of rolling  interest
payments based on the  applicable  interest rate at that time and is adjusted at
regular  intervals  thereafter.  Certain  Brady  Bonds  are  entitled  to "value
recovery  payments"  in  certain  circumstances,   which  in  effect  constitute
supplemental  interest  payments,  but generally are not  collateralized.  Brady
Bonds  are  often  viewed  as  having  up  to  four  valuation  components:  (1)
collateralized  repayment  of principal at final  maturity,  (2)  collateralized
interest  payments,   (3)  uncollateralized   interest  payments,  and  (4)  any
uncollateralized  repayment  of principal  at maturity  (these  uncollateralized
amounts  constitute the "residual risk"). In the event of a default with respect
to  collateralized  Brady Bonds as a result of which the payment  obligations of
the issuer are accelerated,  the U.S.  Treasury zero coupon  obligations held as
collateral  for the payment of principal  will not be  distributed to investors,
nor will such obligations be sold and the proceeds  distributed.  The collateral
will be held by the collateral agent to the scheduled  maturity of the defaulted
Brady  Bonds,  which will  continue  to be  outstanding,  at which time the face
amount of the collateral will equal the principal  payments that would have then
been due on the Brady Bonds in the normal course.  In addition,  in light of the
residual risk of Brady Bonds and, among other  factors,  the history of defaults
with  respect  to  commercial  bank  loans by public  and  private  entities  of
countries  issuing Brady Bonds,  investments  in Brady Bonds are to be viewed as
speculative.

                            REDUCED SALES CHARGES

  Initial  sales   charges  may  be  reduced  or   eliminated   for  persons  or
organizations purchasing Class A shares of the Fund alone or in combination with
Class A shares of other Keystone America Funds.

  For  purposes  of  qualifying  for reduced  sales  charges on  purchases  made
pursuant to Rights of  Accumulation or Letters of Intent,  the term  "Purchaser"
includes the following persons: an individual; an individual,  his or her spouse
and children under the age of 21; a trustee or other fiduciary of a single trust
estate  or  single  fiduciary   account   established  for  their  benefit;   an
organization  exempt from federal income tax under Section 501 (c)(3) or (13) of
the Internal Revenue Code; a pension,  profit-sharing  or other employee benefit
plan whether or not qualified under Section 401 of the Internal Revenue Code; or
other organized  groups of persons,  whether  incorporated or not,  provided the
organization  has been in existence for at least six months and has some purpose
other than the purchase of  redeemable  securities  of a  registered  investment
company at a discount.  In order to qualify for a lower sales charge, all orders
from an  organized  group  will  have to be placed  through a single  investment
dealer or other firm and identified as originating from a qualifying  purchaser.

CONCURRENT PURCHASES
  For purposes of qualifying for a reduced sales charge, a Purchaser may combine
concurrent  direct  purchases of Class A shares of two or more of the  "Eligible
Funds," as defined under "Rights of Accumulation."  For example,  if a Purchaser
concurrently  invested  $75,000 in one of the other "Eligible Funds" and $75,000
in the Fund, the sales charge would be that  applicable to a $150,000  purchase,
i.e.,  3.75% of the offering price, as indicated in the sales charge schedule in
the prospectus.

RIGHT OF ACCUMULATION
  In calculating the sales charge  applicable to current purchases of the Fund's
Class A shares, a Purchaser is entitled to accumulate current purchases with the
current  value of  previously  purchased  Class A shares of the Fund and Class A
shares of certain other  eligible funds that are still held in (or exchanged for
shares of and are still held in) the same or another  eligible  fund  ("Eligible
Fund(s)")  irrespective  of class.  The Eligible Funds are the Keystone  America
Funds and Keystone Liquid Trust.

  For example,  if a Purchaser  held shares  valued at $99,999 and  purchased an
additional $5,000, the sales charge for the $5,000 purchase would be at the next
lower sales  charge of 3.75% of the  offering  price as  indicated  in the sales
charge  schedule.  KIRC  must be  notified  at the  time of  purchase  that  the
Purchaser is entitled to a reduced sales charge, which reduction will be granted
subject to confirmation of the Purchaser's  holdings.  The Right of Accumulation
may be modified or discontinued at any time.

LETTER OF INTENT
  A Purchaser  may qualify for a reduced  sales  charge on a purchase of Class A
shares of the Fund alone or in  combination  with purchases of Class A shares of
any of the other  Eligible  Funds by completing  the Letter of Intent section of
the  application.  By  so  doing,  the  Purchaser  agrees  to  invest  within  a
thirteen-month  period a specified  amount that, if invested at one time,  would
qualify  for a reduced  sales  charge.  Each  purchase  will be made at a public
offering price applicable to a single transaction of the dollar amount specified
on the application,  as described in this prospectus.  The Letter of Intent does
not  obligate  the  Purchaser  to  purchase,  nor the Fund to sell,  the  amount
indicated.

  After the Letter of Intent is received by KIRC,  each  investment made will be
entitled to the sales charge applicable to the level of investment  indicated on
the  application.  The Letter of Intent may be  back-dated  up to ninety days so
that any  investments  made in any of the Eligible  Funds  during the  preceding
ninety-day  period,  valued  at the  Purchaser's  cost,  can be  applied  toward
fulfillment of the Letter of Intent.  However,  there will be no refund of sales
charges  already paid during the ninety-day  period.  No retroactive  adjustment
will be made if purchases  exceed the amount  specified in the Letter of Intent.
Income and capital gains distributions taken in additional shares will not apply
toward completion of the Letter of Intent.

  If total  purchases  made  pursuant  to the Letter of Intent are less than the
amount specified, the Purchaser will be required to remit an amount equal to the
difference  between the sales  charge paid and the sales  charge  applicable  to
purchases  actually made. Out of the initial purchase (or subsequent  purchases,
if necessary) 5% of the dollar amount  specified on the application will be held
in escrow by KIRC in the form of shares  registered in the Purchaser's name. The
escrowed shares will not be available for redemption, transfer or encumbrance by
the Purchaser until the Letter of Intent is completed or the higher sales charge
paid. All income and capital gains distributions on escrowed shares will be paid
to the Purchaser or his order.

  When the minimum  investment  specified  in the Letter of Intent is  completed
(either prior to or by the end of the thirteen-month period), the Purchaser will
be notified and the escrowed shares will be released. If the intended investment
is not  completed,  the  Purchaser  will be  asked  to  remit  to the  Principal
Underwriter any difference  between the sales charge on the amount specified and
on the amount actually attained.  If the Purchaser does not within 20 days after
written  request by the Principal  Underwriter or his dealer pay such difference
in sales charge,  KIRC will redeem an appropriate  number of the escrowed shares
in order to realize such difference.  Shares remaining after any such redemption
will be released  by KIRC.  Any  redemptions  made by the  Purchaser  during the
thirteen-month  period  will be subtracted  from the amount of the purchases for
purposes of determining whether the Letter of Intent has been completed.  In the
event of a total  redemption of the account prior to completion of the Letter of
Intent,  the  additional  sales charge due will be deducted from the proceeds of
the redemption and the balance will be forwarded to the Purchaser.

  By signing the application, the Purchaser irrevocably constitutes and appoints
KIRC his attorney to surrender for  redemption  any or all escrowed  shares with
full power of substitution.

  The Purchaser or his dealer must inform the Principal Underwriter or KIRC that
a Letter of Intent is in effect each time a purchase is made.

                                    THE FUND
- --------------------------------------------------------------------------------

         The Fund is an open-end management investment company commonly known as
a mutual fund.  The Fund is  authorized  to issue series of shares  representing
portfolios of its assets. At this time, the Fund issues shares of one portfolio,
the World Bond Portfolio (the  "Portfolio").  The Portfolio seeks current income
by  investing  primarily  in a  non-diversified  portfolio  consisting  of  debt
securities  denominated  in  United  States  ("U.S.")  and  foreign  currencies.
Interest income will be an important factor in securities selection, but only if
consistent  with  management's  outlook  for  local  bond  prices  and  currency
movements. The Portfolio seeks capital appreciation as a secondary objective.

         Upon  formation,  the  Portfolio  was known as the Global  Income  Plus
Portfolio of  International  Heritage Fund,  which was formed as a Massachusetts
business  trust on  September  5, 1986.  On April 19,  1989,  the  International
Heritage  Fund joined the  Keystone  America  Funds.  In 1989,  the Fund and the
Portfolio  were  renamed  Keystone  America  World  Bond  Fund  and  World  Bond
Portfolio, respectively.

         Certain information about the Fund is contained in its prospectus. This
statement of additional  information  provides additional  information about the
Fund that may be of interest to some investors.

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

         The Fund has  adopted,  on behalf  of the  Portfolio,  the  fundamental
investment  restrictions  set forth below,  which may not be changed without the
vote of a majority  of the  Portfolio's  outstanding  shares.  Unless  otherwise
stated, all references to Portfolio assets are in terms of current market value.

         A portfolio of the Fund may not do the following:

         (1)  issue  senior  securities,   except  as  appropriate  to  evidence
indebtedness  which the  portfolio is permitted to incur  pursuant to Investment
Restriction  (3) and except for shares of any  additional  series or  portfolios
which may be established by the Trustees;

         (2) (a) sell securities  short (except by selling futures  contracts or
covered options),  unless it owns, or by virtue of ownership of other securities
has the right to obtain without additional  consideration,  securities identical
in kind and amount to the securities sold, or (b) purchase securities on margin,
except  for such  short-term  credits  as are  necessary  for the  clearance  of
transactions,  and  provided  that a portfolio  may make  initial and  variation
margin payments in connection with purchases or sales of futures contracts or of
options on futures contracts;

         (3)  borrow  money,  except  from a bank  for  temporary  or  emergency
purposes  (not for  leveraging  or  investment)  and may not borrow  money in an
amount  exceeding  one-third of the value of its total assets (less  liabilities
other  than  borrowings);  any  borrowings  that come to exceed  one-third  of a
portfolio's  total  assets by reason of a decline in net assets  will be reduced
within  three  days  to the  extent  necessary  to  comply  with  the  one-third
limitation;  a portfolio  will not  purchase  securities  while  temporary  bank
borrowings in excess of 5% of its total assets are outstanding;

         (4) underwrite securities issued by others, except to the extent that a
portfolio may be deemed an  underwriter  in connection  with the  disposition of
restricted securities;

         (5) invest in real estate or  mortgages  (but may invest in real estate
investment  trusts or companies whose business  involves the purchase or sale of
real estate or mortgages except real estate limited partnerships) or commodities
or  commodity  contracts,  except  futures  contracts  and  options  on  futures
contracts,  including,  but not limited to contracts for the future  delivery of
securities  or  currency,  contracts  based on  securities  indices  and forward
foreign currency exchange contracts;

         (6) invest 25% or more of the portfolio's total assets (taken at market
value) in  securities  of issuers in a  particular  industry or group of related
industries, except U.S. government securities;

         (7) make  loans,  except (a)  through  the  purchase of a portion of an
issue of publicly  distributed debt securities in accordance with its investment
objective,  policies  and  restrictions,  and  (b) by  entering  into  (i)  loan
transactions and (ii) repurchase agreements with respect to portfolio securities
if, as a result  thereof,  not more  than 25% of the  portfolio's  total  assets
(taken at current value) would be subject to loan transactions;

         (8)  invest in  companies  for the  purpose  of  exercising  control or
management,  provided,  however,  that  this  limitation  shall not  preclude  a
portfolio from  exercising its rights as a security  holder to participate in or
influence  decisions to be made by the security  holders or  management  of such
companies  with  respect  to  matters  affecting  the  value of such  companies'
securities or the interests of the portfolio;

         (9) pledge, mortgage or hypothecate its assets, except that a portfolio
may pledge not more than  one-third of its total assets (taken at current value)
to secure  borrowings made in accordance with Investment  Restriction (3) above,
and provided that a portfolio may make initial and variation  margin payments in
connection with purchases or sales of futures contracts or of options on futures
contracts;

         (10) invest in oil, gas or other  mineral  exploration  or  development
programs  (although a portfolio  may invest in companies  which own or invest in
such interests);

         (11) purchase or retain the securities of any issuer, if, to the Fund's
knowledge,  those  Trustees  or  directors  and  officers  of  the  Fund  or its
investment manager or advisers,  who individually own beneficially more than 1/2
of 1% of the outstanding  securities of such issuer,  together own  beneficially
more than 5% of such outstanding securities; and

         (12) purchase securities of any one issuer if as a result more than 10%
of the  outstanding  voting  securities  of  such  issuer  would  be held by the
portfolio,  or invest more than 5% of the  portfolio's  total  assets  (taken at
market value) in the securities of any one issuer,  except  securities issued or
guaranteed by the U.S.  government or any of its agencies or  instrumentalities,
provided that a portfolio may invest up to 25% of its total assets in securities
issued or guaranteed by any single foreign government and up to 10% of its total
assets in securities issued or guaranteed by any single multinational agency.

         The Fund has adopted the  nonfundamental  policies set forth below,  in
order to permit the sale of shares in certain states, which may be changed as to
any portfolio without shareholder approval or notification.

         A portfolio may not do the following:

         (1) pledge,  mortgage or hypothecate  its assets in excess of an amount
equal to 10% of its net assets,  except to secure  borrowings made in accordance
with Investment  Restriction (3) above, and provided that the portfolio may make
initial and variation  margin  payments in connection with purchases or sales of
futures contracts or of options on futures contracts;

         (2) purchase any option on  securities  or a securities  index if, as a
result,  the aggregate  premiums paid for all options it owns would exceed 5% of
its net assets at the time of such purchase;

         (3) purchase warrants,  valued at the lower of cost or market,in excess
of 5% of the value of the portfolio's  net assets;  included within that amount,
but not to exceed 2% of the value of the portfolio's net assets, may be warrants
which  are not  listed on the New York or  American  Stock  Exchanges;  warrants
acquired by the portfolio at any time in units or attached to securities are not
subject to this restriction;

         (4) purchase the securities of any issuer if, as a result, more than 5%
of the  portfolio's  total assets (taken at current  value) would be invested in
the securities of companies which, including predecessors, have a record of less
than three years' continuous operation,  except obligations issued or guaranteed
by the U.S.  government or a foreign government or their respective agencies and
instrumentalities and except securities of closed-end investment companies;

         (5) enter into futures  contracts if, as a result,  the aggregate value
of initial margin deposits made by a portfolio in connection with such contracts
and  premiums  paid for options on futures  would  exceed 5% of the value of the
portfolio's total assets;

         (6) write  covered  options,  unless  the  securities  underlying  such
options are listed on a national  securities exchange and the options are issued
by the Options  Clearing  Corporation,  provided,  however,  that the securities
underlying  such  options  may be  traded  on  the  automated  quotation  system
("NASDAQ") of the National Association of Securities Dealers, Inc. ("NASD"), if,
and to the extent, permitted by applicable state regulations;

         (7) write or sell covered call or put options with respect to more than
25% of the portfolio's net assets at the time such options are written, purchase
protective  puts with a value in excess of 25% of the  portfolio's net assets or
purchase calls and puts,  other than protective  puts, with a value in excess of
5% of the portfolio's net assets;

         (8) purchase the securities of other registered  investment  companies,
except (a) securities of a "money market" fund sponsored,  managed or advised by
one of the Fund's investment advisers,  or an affiliate thereof, but only to the
extent authorized by an order of the Securities and Exchange Commission,  (b) by
purchase in the open market when no  commission or profit to a sponsor or dealer
results from such purchase, other than the customary broker's commission, or (c)
when such  purchase,  though not made on the open  market,  is part of a plan of
merger or consolidation;

         (9) simultaneously purchase and sell the same or an equivalent security
in order to profit from price discrepancies; and

         (10)  invest in oil, gas and other mineral leases.

         The Portfolio's  purchase of securities of other  investment  companies
would result in a layering of expenses,  such that the Portfolio's  shareholders
would indirectly bear a proportionate  share of the expenses of those investment
companies,  including  operating costs,  investment  advisory and administrative
fees.  The Portfolio  does not  anticipate  purchasing  the  securities of other
investment companies.

         The Fund  intends to follow  policies of the  Securities  and  Exchange
Commission  as they are  adopted  from time to time  with  respect  to  illiquid
securities,  including, at this time, (1) treating as illiquid, securities which
may not be sold or disposed of in the ordinary  course of business  within seven
days at approximately  the value at which the Fund has valued such securities on
its books and (2) limiting its holdings of such securities to 15% of net assets.

- --------------------------------------------------------------------------------
                              DIVIDENDS AND TAXES
- --------------------------------------------------------------------------------

         The Fund  intends to  distribute  dividends  from the  Portfolio's  net
investment income monthly and all net realized  long-term capital gains, if any,
annually.  Fund  distributions  are made in  additional  shares of that class of
shares  upon  which  the  distribution  is  based  or,  at  the  option  of  the
shareholder,  in cash. Shareholders who have not opted, prior to the record date
for any  distribution,  to  receive  cash  will have the  number of such  shares
determined on the basis of net asset value per share  computed at the end of the
day on the record date after adjustment for the distribution. Net asset value is
used in  computing  the number of shares in both  gains and income  distribution
reinvestments. Account statements and/or checks as appropriate will be mailed to
shareholders within seven days after the Fund pays the distribution.  Unless the
Fund receives  instructions to the contrary from a shareholder before the record
date, it will assume that the  shareholder  wishes to receive that  distribution
and future gains and income  distributions in shares.  Instructions  continue in
effect until changed in writing.

         Distributed  long-term  capital  gains  are  taxable  as  such  to  the
shareholder  whether  received  in cash or in  additional  Portfolio  shares and
regardless  of the  period  of  time  Portfolio  shares  have  been  held by the
shareholder.  However, if such shares are held less than six months and redeemed
at a loss,  the  shareholder  will  recognize a long term  capital  loss on such
shares to the extent of the  long-term  capital gains  distribution  received in
connection with such shares. If the net asset value of the Portfolio's shares is
reduced  below a  shareholder's  cost by any capital  gains  distribution,  such
distribution,  to the extent of the reduction,  would be a return of investment,
though taxable as stated above. Since distributions of capital gains depend upon
profits actually realized from the sale of securities by the Portfolio, they may
or may not occur. The foregoing  comments  relating to the taxation of dividends
and distributions paid on the Portfolio's shares relate solely to federal income
taxation.  Such  dividends  and  distributions  may also be subject to state and
local taxes.

         When the Fund  makes a  distribution  on  behalf of the  Portfolio,  it
intends to distribute  only the Portfolio's net capital gains and such income as
has been  pre-determined  to the best of the  Fund's  ability  to be  taxable as
ordinary  income.  Shareholders of the Portfolio will be advised annually of the
federal income tax status of distributions.

         If more than 50% of the value of the  Portfolio's  total  assets at the
end of a fiscal year is  represented by securities of foreign  corporations  and
the Fund  elects  to make  foreign  tax  credits  available  to the  Portfolio's
shareholders, a shareholder will be required to include in his gross income both
cash  dividends  and the amount the Fund  advises him is his pro rata portion of
income taxes withheld by foreign governments from interest and dividends paid on
the Portfolio's investments.  The shareholder will be entitled, however, to take
his share of the amount of such foreign taxes  withheld as a credit  against his
U.S.  income  tax,  or to treat  his share of the  foreign  tax  withheld  as an
itemized deduction from his gross income, if that should be to his advantage. In
substance,  this policy enables the shareholder to benefit from the same foreign
tax  credit  or  deduction  that he  would  have  received  if he had  been  the
individual  owner of foreign  securities  and had paid foreign income tax on the
income therefrom.  As in the case of individuals  receiving income directly from
foreign  sources,  the above  described tax credit and deductions are subject to
certain limitations.

- --------------------------------------------------------------------------------
                            VALUATION OF SECURITIES
- --------------------------------------------------------------------------------

         Current  values  for  the  Portfolio's  securities  are  determined  as
follows:

         (1) Common stock, preferred stock and other equity securities listed on
the New York Stock Exchange (the "Exchange") are valued on the basis of the last
sale price on the Exchange.  In the absence of any sales,  such  securities  are
valued at the mean between the closing asked price and the closing bid price.

         (2) Common stock, preferred stock and other equity securities listed on
other U.S. or foreign  exchanges  will be valued as described in (1) above using
quotations on the exchange on which the security is most extensively traded.

         (3) Common stock,  preferred stock and other equity securities unlisted
and quoted on the  National  Market  System  ("NMS") are valued at the last sale
price,  provided  a sale  has  occurred.  In the  absence  of  any  sales,  such
securities  are valued at the high or "inside" bid, which is the bid supplied by
the NASD on its NASDAQ  system  for  securities  traded in the  over-the-counter
market.

         (4) Common stock, preferred stock and other equity securities quoted on
the NASDAQ  system,  but not listed on NMS,  are valued at the high or  "inside"
bid.

         (5) Common  stock,  preferred  stock and other  equity  securities  not
listed and not quoted on the NASDAQ System and for which over-the-counter market
quotations are readily  available are valued at the mean between the current bid
and asked prices for such securities.

         (6) Non-U.S.  common stock, preferred stock and other equity securities
not listed or listed and  subject to  restrictions  on sale are valued at prices
supplied  by  a  dealer  selected  by  Keystone  Investment  Management  Company
(formerly named Keystone Custodian Funds, Inc.) ("Keystone").

         (7) Bonds, debentures and other debt securities,  whether or not listed
on any national securities exchange, are valued at a price supplied by a pricing
service or a bond dealer selected by Keystone.

         (8) Short-term  instruments  having  maturities of more than sixty days
for which market  quotations are readily  available are valued at current market
value. Where market quotations are not available, such instruments are valued at
fair value as determined by the Fund's Board of Trustees.

         (9) Short-term instruments maturing in sixty days or less are valued at
amortized cost (original  purchase cost as adjusted for  amortization of premium
or  accretion  of  discount),   which,  when  combined  with  accrued  interest,
approximates  market.  Short-term  instruments  maturing in more than sixty days
when purchased that are held on the sixtieth day prior to maturity are valued at
amortized  cost (market value on the sixtieth day adjusted for  amortization  of
premium or accretion of discount),  which,  when combined with accrued interest,
approximates market.

         (10) Options, futures contracts and options on futures listed or traded
on a  national  securities  exchange  are  valued at the last sale price on such
exchange  prior to the time of  determining  net  asset  value or, if no sale is
reported, are valued at the mean between the most recent bid and asked prices.

         (11) Forward currency contracts are valued at their last sales price as
reported  by a pricing  service,  and,  in the  absence of a report,  at a value
determined on the basis of the underlying currency at prevailing exchange rates.

         (12)  Securities  subject to  restrictions on resale are valued at fair
value at least  monthly by a pricing  service  under the direction of the Fund's
Board of Trustees.

         (13) All other assets are valued at fair market value as  determined by
or under the direction of the Fund's Board of Trustees.

- --------------------------------------------------------------------------------
                                   BROKERAGE
- --------------------------------------------------------------------------------

         It is the policy of the Fund, in effecting  transactions  in securities
for the  Portfolio,  to seek best  execution  of  orders  at the most  favorable
prices. The determination of what may constitute best execution and price in the
execution  of a  securities  transaction  by  a  broker  involves  a  number  of
considerations,  including,  without limitation, the overall direct net economic
result  to the  Portfolio  (involving  both  price  paid  or  received  and  any
commissions and other costs paid),  the efficiency with which the transaction is
effected,  the ability to effect the  transaction  at all where a large block is
involved,  the availability of the broker to stand ready to execute  potentially
difficult transactions in the future and the financial strength and stability of
the broker.  Such  considerations  are weighed by management in determining  the
overall reasonableness of brokerage commissions paid.

         Subject to the  foregoing,  a factor in the selection of brokers is the
receipt of research services,  such as analyses and reports concerning  issuers,
industries, securities, economic factors and trends as well as other statistical
and factual information (including related computer services and equipment). Any
such research and other statistical and factual information  provided by brokers
to the Fund or Keystone are  considered  to be in addition to and not in lieu of
services required to be performed by Keystone under its Investment  Advisory and
Management  Agreement with the Fund. The cost, value and specific application of
such information are  indeterminable  and cannot be practically  allocated among
the Fund and other  clients of  Keystone  who may  indirectly  benefit  from the
availability of such  information.  Similarly,  the Fund may indirectly  benefit
from  information  made available as a result of transactions  effected for such
other clients.  Under its Investment Advisory and Management  Agreement with the
Fund,  Keystone is permitted to pay higher  brokerage  commissions for brokerage
and  research  services  in  accordance  with  Section  28(e) of the  Securities
Exchange Act of 1934. In the event Keystone does follow such a practice, it will
do so on a basis that is fair and equitable to the Fund.

         The  Fund  expects  that  purchases  and  sales of  securities  for the
Portfolio usually will be principal  transactions.  Such securities are normally
purchased  directly from the issuer or from an  underwriter  or market maker for
the securities.  There usually will be no brokerage commissions paid by the Fund
for such purchases.  Purchases from  underwriters  will include the underwriting
commission or concession,  and purchases  from dealers  serving as market makers
will  include  a  dealer's  mark up or  reflect  a  dealer's  mark  down.  Where
transactions are made in the  over-the-counter  market,  the Fund will deal with
primary market makers unless more favorable prices are otherwise obtainable.

         The Fund may participate, if and when practicable, in group bidding for
the  direct  purchase  from an  issuer of  certain  securities,  thereby  taking
advantage of the lower purchase price available to such a group.

         Neither  Keystone  nor  the  Fund  has any  intention  of  placing  the
Portfolio's securities  transactions with any particular  broker-dealer or group
thereof. The Fund's Board of Trustees has determined, however, that the Fund may
follow a policy of  considering  sales of shares of the Portfolio as a factor in
the selection of broker-dealers to execute  portfolio  transactions,  subject to
the requirements of best execution, described above.

         In addition, securities for the Portfolio will not be purchased from or
sold to Keystone, the Principal Underwriter,  or any of their affiliated persons
except in accordance  with the  Investment  Company Act of 1940 (the "1940 Act")
and rules and regulations issued thereunder.

         Investment  decisions  for the Portfolio  are made  independently  from
those of the other funds and  investment  accounts  managed by Keystone.  It may
frequently develop,  however, that the same investment decision is made for more
than one fund.  Simultaneous  transactions are inevitable when the same security
is suitable for the investment  objective of more than one account.  When two or
more funds or accounts are engaged in the purchase or sale of the same security,
the transactions are allocated as to amount in accordance with a formula that is
equitable  to each fund or  account.  It is  recognized  that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as the Portfolio is concerned.  In other cases, however, it is believed that
the ability of the Portfolio to participate in volume  transactions will produce
better  executions for the  Portfolio.  It is the opinion of the Fund's Board of
Trustees that the  desirability of retaining  Keystone as investment  adviser to
the  Fund  outweighs  any  disadvantages   that  may  result  from  exposure  to
simultaneous transactions.

         The  policy  of the  Fund  with  respect  to  brokerage  is and will be
reviewed  by the  Fund's  Board of  Trustees  from time to time.  Because of the
possibility  of  further  regulatory   developments   affecting  the  securities
exchanges  and brokerage  practices  generally,  the foregoing  practices may be
changed, modified or eliminated.

         During the fiscal years ended  December 31, 1992 and 1993, the Fund did
not pay any brokerage commissions. During the ten month period ended October 31,
1994, the Fund paid $9,000 in brokerage commissions.

- --------------------------------------------------------------------------------
                                 SALES CHARGES
- --------------------------------------------------------------------------------

GENERAL

         Generally,  the Fund offers three classes of shares. Class A shares are
offered with a maximum  front-end  sales charge of 4.75%  payable at the time of
purchase ("Front End Load Option"). Class B shares purchased on or after June 1,
1995 are subject to a contingent  deferred sales charge payable upon  redemption
during  the 72 month  period  following  the month of  purchase.  Class B shares
purchased  prior to June 1, 1995 are  subject  to a  contingent  deferred  sales
charge  upon  redemption  within  three  calendar  years  following  the year of
purchase ("Back End Load Option").  Class B shares purchased on or after June 1,
1995 that have been outstanding eight years following the month of purchase will
automatically  convert to Class A shares without imposition of a front-end sales
charge or exchange fee. Class B shares purchased prior to June 1, 1995 that have
been outstanding  during seven calendar years will similarly  convert to Class A
shares.  (Conversion of Class B shares  represented by stock  certificates  will
require  the return of the stock  certificates  to  Keystone  Investor  Resource
Center, Inc., the Fund's transfer and dividend disbursing agent ("KIRC").) Class
C shares are sold subject to a  contingent  deferred  sales charge  payable upon
redemption within one year after purchase ("Level Load Option").  Class C shares
are available  only through  dealers who have entered into special  distribution
agreements  with the Principal  Underwriter.  The prospectus  contains a general
description  of how  investors may buy shares of the Fund, as well as a table of
applicable  sales  charges for Class A shares,  a  discussion  of reduced  sales
charges that may apply to subsequent  purchases and a description  of applicable
contingent deferred sales charges.

CONTINGENT DEFERRED SALES CHARGES

         In order to  reimburse  the Fund for certain  expenses  relating to the
sale of its shares (See  "Distribution  Plans"),  a  contingent  deferred  sales
charge is imposed at the time of redemption of certain Fund shares, as follows:

CLASS A SHARES

         With certain  exceptions,  purchases of Class A shares made on or after
April 10, 1995 (1) in an amount equal to or exceeding $1,000,000 and/or (2) by a
corporate  qualified  retirement plan or a non-qualified  deferred  compensation
plan  sponsored  by a  corporation  having  100 or more  eligible  employees  (a
"Qualifying  Plan"),  in either case without a front-end  sales charge,  will be
subject  to a  contingent  deferred  sales  charge of 1.00%  during the 24 month
period following the date of purchase.  Certain Class A shares purchased without
a front-end  sales charge prior to April 10, 1995 may be subject to a contingent
deferred  sales  charge of 0.25%  upon  redemption  during the  one-year  period
commencing on the date such shares were  originally  purchased.  The  contingent
deferred  sales  charge  will be  retained  by the  Principal  Underwriter.  See
"Calculation of Contingent Deferred Sales Charge" below.

CLASS B SHARES

         With respect to Class B shares  purchased on or after June 1, 1995, the
Fund,  with  certain  exceptions,  will  impose a  deferred  sales  charge  as a
percentage  of the lesser of net asset  value or net cost of such Class B shares
redeemed during succeeding  twelve-month periods following the month of purchase
as follows:  5% during the first period;  4% during the second period; 3% during
the third period; 3% during the fourth period;  2% during the fifth period;  and
1% during  the sixth  period.  No  deferred  sales  charge is imposed on amounts
redeemed  thereafter.  See  "Calculation  of Contingent  Deferred  Sales Charge"
below.

         With  respect to Class B shares  sold prior to June 1, 1995,  the Fund,
with certain exceptions,  will impose a deferred sales charge of 3.00% on shares
redeemed during the calendar year of purchase and during the first calendar year
after  purchase;  2.00% on shares redeemed during the second calendar year after
purchase;  and 1.00% on shares  redeemed  during the third  calendar  year after
purchase. No deferred sales charge is imposed on amounts redeemed thereafter.

         When imposed, the deferred sales charge is deducted from the redemption
proceeds  otherwise payable to you. The deferred sales charge is retained by the
Principal  Underwriter.  Amounts received by the Principal Underwriter under the
Class B Distribution Plans are reduced by deferred sales charges retained by the
Principal  Underwriter.  See  "Calculation of Contingent  Deferred Sales Charge"
below.

CLASS C SHARES

         With certain  exceptions,  the Fund will impose a deferred sales charge
of 1% on shares redeemed within one year after the date of purchase. No deferred
sales charge is imposed on amounts redeemed thereafter.

         When imposed, the deferred sales charge is deducted from the redemption
proceeds  otherwise payable to you. The deferred sales charge is retained by the
Principal  Underwriter.  See  "Calculation of Contingent  Deferred Sales Charge"
below.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE

         Any  contingent  deferred  sales charge  imposed upon the redemption of
Class A, Class B or Class C shares is a percentage  of the lesser of (1) the net
asset value of the shares redeemed or (2) the net cost of such shares.

         No contingent  deferred sales charge is imposed when you redeem amounts
derived from (1)  increases  in the value of your account  above the net cost of
such shares due to increases  in the net asset value per share of the Fund;  (2)
certain  shares  with  respect  to which  the Fund did not pay a  commission  on
issuance,  including shares acquired through reinvestment of dividend income and
capital gains  distributions;  (3) certain Class A shares held for more than one
or two years, as the case may be, from the date of purchase;  (4) Class B shares
held during  more than four  consecutive  calendar  years or more than 72 months
after the month of purchase,  as the case may be; or (5) Class C shares held for
more than one year from the date of purchase.

         Upon  request  for  redemption,  shares not  subject to the  contingent
deferred  sales  charge  will be  redeemed  first.  Thereafter,  shares held the
longest will be the first to be redeemed.  There is no contingent deferred sales
charge when the shares of a class are exchanged for the shares of the same class
of another Keystone America Fund.  Moreover,  when shares of one such class of a
fund  have been  exchanged  for  shares of  another  such  class of a fund,  the
calendar  year of the  purchase  of the  shares  of the fund  exchanged  into is
assumed to be the year shares tendered for exchange were originally purchased.

WAIVER OF SALES CHARGES

         Shares of the Portfolio  may also be sold,  to the extent  permitted by
applicable law, regulations,  interpretations or exemptions,  at net asset value
without the  imposition of an initial  sales charge to (1) an eligible  officer,
Director,  Trustee,  full-time  employee  or sales  representative  of the Fund,
Keystone,  Keystone  Investments,  Inc.  (formerly named Keystone  Group,  Inc.)
("Keystone  Investments"),  their subsidiaries or the Principal  Underwriter who
have been such for not less than ninety days;  (2) a pension and  profit-sharing
plan  established by such companies,  their  subsidiaries and affiliates for the
benefit of their officers,  Directors,  Trustees,  full-time employees and sales
representatives;  or (3) a  registered  representative  of a firm  with a dealer
agreement with the Principal Underwriter,  provided all such sales are made upon
written assurance that the purchase is made for investment purposes and that the
securities will not be resold except through redemption by the Fund.

         No  initial  sales  charge is  imposed  on  purchases  of shares of the
Portfolio  by a bank or trust  company  in a single  account in the name of such
bank or trust  company  as trustee if the  initial  investment  in shares of the
Portfolio  or any fund in the  Keystone  Investments  Family of Funds  purchased
pursuant to this waiver,  is at least  $500,000 and any  commission  paid at the
time of such purchase is not more than 1% of the amount  invested.  In addition,
no deferred sales charge is imposed on redemptions of such shares.

         With respect to Class A shares  purchased  by a Qualifying  Plan at net
asset value or Class C shares  purchased by a  Qualifying  Plan,  no  contingent
deferred sales charge will be imposed on any redemptions made specifically by an
individual  participant in the Qualifying  Plan. This waiver is not available in
the  event a  Qualifying  Plan,  as a whole,  redeems  substantially  all of its
assets.

         In  addition,  no  contingent  deferred  sales  charge is  imposed on a
redemption  of shares of the Fund in the event of (1) death or disability of the
shareholder; (2) a lump-sum distribution from a benefit plan qualified under the
Employee  Retirement  Income  Security  Act of  1974  ("ERISA");  (3)  automatic
withdrawals  from ERISA plans if the  shareholder  is at least 59 1/2 years old;
(4)  involuntary  redemptions of accounts having an aggregate net asset value of
less than $1,000; (5) automatic  withdrawals under an automatic  withdrawal plan
of up to 1.5% per  month  of the  shareholder's  initial  account  balance;  (6)
withdrawals  consisting of loan proceeds to a retirement plan  participant;  (7)
financial  hardship  withdrawals made by a retirement plan  participant;  or (8)
withdrawals  consisting of returns of excess  contributions  or excess  deferral
amounts made to a retirement plan participant.

         Please see the prospectus for additional  information regarding waivers
of sales charges.

REDEMPTION OF SHARES

         The Fund has obligated itself under the 1940 Act to redeem for cash all
shares  presented for redemption by any one  shareholder in any 90 day period up
to the lesser of $250,000 or 1% of the Fund's assets.

- --------------------------------------------------------------------------------
                               DISTRIBUTION PLANS
- --------------------------------------------------------------------------------

         Rule 12b-1 under the 1940 Act permits investment companies, such as the
Fund, to use their assets to bear expenses of distributing  their shares if they
comply  with  various  conditions,  including  adoption of a  distribution  plan
containing certain provisions set forth in Rule 12b-1. The Fund's Class A, B and
C  Distribution  Plans  have been  approved  by the  Fund's  Board of  Trustees,
including a majority of the Trustees who are not interested  persons of the Fund
as  defined  in the 1940 Act  ("Independent  Trustees")  and a  majority  of the
Trustees who have no direct or indirect  financial  interest in the Distribution
Plans, or any agreement  related thereto (the "Rule 12b-1 Trustees," who are the
same as the Independent Trustees).

         The NASD limits the amount that a Fund may pay annually in distribution
costs for sale of its shares  and  shareholder  service  fees.  The NASD  limits
annual  expenditures to 1% of the aggregate average daily net asset value of its
shares, of which 0.75% may be used to pay such distribution  costs and 0.25% may
be used to pay  shareholder  service  fees.  The NASD also limits the  aggregate
amount that the Fund may pay for such distribution costs to 6.25% of gross share
sales since the  inception of the 12b-1 Plans,  plus  interest at the prime rate
plus 1% on such amounts  (less any  contingent  deferred  sales  charges paid by
shareholders to the Principal Underwriter).

         CLASS A DISTRIBUTION  PLAN. The Class A Distribution Plan provides that
the Fund may expend daily amounts at an annual rate, which is currently  limited
up to 0.25% of the Fund's average daily net asset value  attributable to Class A
shares, to finance any activity that is primarily intended to result in the sale
of Class A shares,  including,  without limitation,  expenditures  consisting of
payments to the  principal  underwriter  of the Fund  (currently  the  Principal
Underwriter)  to  enable  the  Principal  Underwriter  to pay or to have paid to
others who sell Class A shares a service or other fee, at such  intervals as the
Principal Underwriter may determine,  in respect of Class A shares maintained by
any such recipients outstanding on the books of the Fund for specified periods.

         Amounts  paid by the  Fund  under  the  Class A  Distribution  Plan are
currently used to pay others, such as dealers, service fees at an annual rate of
up to 0.25% of the average net asset value of Class A shares  maintained by such
others outstanding on the books of the Fund for specified periods.

         CLASS B DISTRIBUTION PLANS. The Fund has adopted Distribution Plans and
other plans with  respect to its Class B shares that  provide  that the Fund may
expend  daily  amounts at an annual  rate of up to 1.00% of the  Fund's  average
daily net asset value  attributable  to Class B shares to finance  any  activity
that is primarily  intended to result in the sale of Class B shares,  including,
without  limitation,  expenditures  consisting  of  payments  to  the  principal
underwriter of the Fund (currently the Principal  Underwriter) (1) to enable the
Principal Underwriter to pay to others (dealers) commissions in respect of Class
B shares sold since  inception of the  Distribution  Plan; and (2) to enable the
Principal  Underwriter  to pay or to have paid to others a service  fee, at such
intervals as the  Principal  Underwriter  may  determine,  in respect of Class B
shares  maintained by any such  recipients  outstanding on the books of the Fund
for specified periods.

         The  Principal  Underwriter  generally  reallows to brokers or others a
commission equal to 4.00% of the price paid for each Class B share sold plus the
first year's service fee in advance in the amount of 0.25% of the price paid for
each Class B share sold. Beginning approximately 12 months after the purchase of
a Class B share,  the broker or other party  receives  service fees at an annual
rate of  0.25% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods.

         The Principal Underwriter intends, but is not obligated, to continue to
pay or accrue  distribution  charges  incurred  in  connection  with the Class B
Distribution  Plans that exceed current annual payments permitted to be received
by the Principal Underwriter from the Fund. The Principal Underwriter intends to
seek full payment of such charges from the Fund (together  with annual  interest
thereon at the prime rate plus one  percent)  at such time in the future as, and
to the extent that,  payment  thereof by the Fund would be within the  permitted
limits.

         If the Fund's Independent Trustees authorize such payments,  the effect
would be to extend the period of time  during  which the Fund incurs the maximum
amount  of  costs  allowed  by  a  Class  B  Distribution  Plan.  If a  Class  B
Distribution  Plan  is  terminated,  the  Principal  Underwriter  will  ask  the
Independent  Trustees to take whatever  action they deem  appropriate  under the
circumstances with respect to payment of such amounts.

         In  connection  with  financing  its  distribution   costs,   including
commission advances to dealers and others, the Principal Underwriter has sold to
a financial institution substantially all of its 12b-1 fee collection rights and
contingent  deferred sales charge collection rights in respect of Class B shares
sold during the two-year period commencing  approximately June 1, 1995. The Fund
has  agreed  not to reduce  the rate of payment of 12b-1 fees in respect of such
Class B shares unless it terminates such shares'  Distribution  Plan completely.
If it terminates  such  Distribution  Plan,  the Fund may be subject to possible
adverse distribution consequences.

         CLASS C DISTRIBUTION  PLAN. The Class C Distribution Plan provides that
the Fund may expend daily amounts at an annual rate of up to 1.00% of the Fund's
average  daily net asset  value  attributable  to Class C shares to finance  any
activity  that is  primarily  intended  to result in the sale of Class C shares,
including,  without  limitation,  expenditures  consisting  of  payments  to the
principal  underwriter of the Fund (currently the Principal  Underwriter) (1) to
enable the  Principal  Underwriter  to pay to others  (dealers)  commissions  in
respect of Class C shares sold since inception of the Distribution Plan; and (2)
to enable the Principal  Underwriter  to pay or to have paid to others a service
fee, at such intervals as the Principal Underwriter may determine, in respect of
Class C shares maintained by any such recipients outstanding on the books of the
Fund for specified periods.

         The  Principal  Underwriter  generally  reallows to brokers or others a
commission  in the amount of 0.75% of the price paid for each Class C share sold
plus the first year's service fee in advance in the amount of 0.25% of the price
paid for each Class C share sold. Beginning  approximately  fifteen months after
purchase,  brokers or others  receive a  commission  at an annual  rate of 0.75%
(subject  to NASD rules)  plus  service  fees at the annual rate of 0.25% of the
average daily net asset value of each Class C share maintained by the recipients
outstanding on the books of the Fund for specified periods.

DISTRIBUTION PLANS IN GENERAL

         Whether any expenditure under a Distribution Plan is subject to a state
expense  limit will depend upon the nature of the  expenditure  and the terms of
the state law,  regulation or order  imposing the limit. A portion of the Fund's
Distribution  Plan expenses may be includable in the Portfolio's total operating
expenses for purposes of determining compliance with state expense limits.

         A  Distribution  Plan  may be  terminated  at any  time  by a vote of a
majority  of the Fund's  Rule  12b-1  Trustees  or by vote of a majority  of the
outstanding  voting  shares of the  respective  class of Portfolio  shares.  Any
change in a Distribution  Plan that would  materially  increase the distribution
expenses  of  the  Portfolio  provided  for  in  a  Distribution  Plan  requires
shareholder  approval.  Otherwise,  a  Distribution  Plan may be  amended by the
Trustees, including the Fund's Rule 12b-1 Trustees.

         Unreimbursed  distribution  expenses at October 31, 1994 were  $230,824
under  the  Class  B  Distribution  Plans  (6.47%  of  Class  B's  net  assets).
Unreimbursed  distribution  expenses at October 31, 1994 were $110,525 under the
Class C Distribution Plan (6.95% of Class C's net assets).

         While a  Distribution  Plan is in effect,  the Fund will be required to
commit the selection and  nomination of candidates for  Independent  Trustees to
the discretion of the Independent Trustees.

         The total amounts paid by the Fund under the foregoing arrangements may
not exceed the maximum  Distribution Plan limit specified above. The amounts and
purposes of expenditures  under a Distribution Plan must be reported to the Rule
12b-1 Trustees quarterly. The Rule 12b-1 Trustees may require or approve changes
in the  implementation  or operation of a Distribution Plan and may also require
that total  expenditures  by the Fund under a  Distribution  Plan be kept within
limits lower than the maximum amount permitted by a Distribution  Plan as stated
above.

         The Independent  Trustees of the Fund have determined that the sales of
the Portfolio's  shares resulting from payments under the Distribution Plans are
expected to benefit the Portfolio.

         For the ten month  period  ended  October 31,  1994,  the Fund paid the
Principal Underwriter $13,778 pursuant to its Class A Distribution Plan. For the
ten month period ended October 31, 1994, the Fund paid the Principal Underwriter
$26,882 and  $14,984  pursuant  to its Class B and Class C  Distribution  Plans,
respectively. These amounts were used to pay commissions and service fees.

                                 FUND EXPENSES
- --------------------------------------------------------------------------------

         In addition to its investment advisory and management fee, the Fund, on
behalf of the  Portfolio,  assumes  and pays its direct  expenses  and all other
expenses,  including,  without  limitation,  the following:  (1) all charges and
expenses  of  any  custodian  or  depository  appointed  by  the  Fund  for  the
safekeeping of the Fund's cash,  securities and other property;  (2) all charges
and expenses for bookkeeping  and auditors;  (3) all charges and expenses of any
transfer  agents  and  registrars  appointed  by the  Fund;  (4) all fees of all

affiliates;  (5) all  brokers'  fees,  expenses  and  commissions  and issue and
transfer taxes chargeable to the Fund in connection with transactions  involving

                               INVESTMENT ADVISER
- --------------------------------------------------------------------------------

         Keystone,  located  at  200  Berkeley  Street,  Boston,   Massachusetts
02116-5034,  organized in 1932, has been retained  under an Investment  Advisory
and Management Agreement (the "Advisory Agreement") to provide investment advice
and, in general,  to manage the investment and reinvestment of the assets of the
Portfolio.

         Keystone is a wholly-owned subsidiary of Keystone Investments,  located
at 200 Berkeley Street, Boston,  Massachusetts 02116-5034.  Keystone Investments
is a corporation predominantly owned by current and former members of management
of Keystone and its affiliates.  The shares of Keystone Investments common stock
beneficially  owned by  management  are held in a number of voting  trusts,  the
trustees  of which are  George S.  Bissell,  Albert H.  Elfner,  III,  Edward F.
Godfrey and Ralph J. Spuehler,  Jr. Keystone  Investments  provides  accounting,
bookkeeping,  legal,  personnel  and general  corporate  services  to  Keystone,
Hartwell  Keystone,  their  affiliates  and the Keystone  Investments  Family of
Funds.

         The overall supervision and management of the Fund rests with its Board
of Trustees. Pursuant to the Advisory Agreement,  Keystone furnishes to the Fund
investment advisory,  management and administrative services, office facilities,
equipment  and  personnel  in  connection  with its  services  for  managing the
investment and reinvestment of the Portfolio's assets, and pays (or causes to be
paid) the compensation of all officers and employees of the Fund.

         As compensation for its services to the Portfolio, Keystone is entitled
to a fee at the annual rate set forth below:

                                                             Aggregate Net Asset
Management                                                   Value of the Shares
Fee                                  Income                     of the Portfolio
- --------------------------------------------------------------------------------
                                 1.5% of Gross
                                  Income Plus
0.50%    of the first                                       $  500,000,000, plus
0.45%    of the next                                        $  500,000,000, plus
0.40%    of amounts over                                    $1,000,000,000
- --------------------------------------------------------------------------------

computed as of the close of business on each business day and paid daily.

         For the ten month period ended October 31, 1994,  the Portfolio paid to
Keystone fees of $61,697, which represented 0.50% of the Portfolio's average net
assets.  For the fiscal years ended  December 31, 1992 and 1993,  the  Portfolio
paid to Keystone fees of $53,621 and $49,732, respectively.

         All expenses (other than those specifically  referred to as being borne
by Keystone)  incurred in the operation of the Fund, and any public  offering of
its shares,  are borne by the Fund. To the extent that Keystone provides certain
of such  services,  the Fund  promptly  reimburses  Keystone  therefor.  The fee
charged  to the Fund is  higher  than  that  charged  to most  other  investment
companies with different investment objectives and policies. However, the fee is
comparable  to fees  charged to other  global and  international  funds that are
subject to the higher costs  involved in managing a portfolio  of  predominantly
international securities.

         Under the Advisory  Agreement,  any liability of Keystone in connection
with  rendering  services  thereunder  is limited to  situations  involving  its
willful  misfeasance,  bad faith,  gross negligence or reckless disregard of its
duties.

         The  Advisory  Agreement  continues in effect from year to year only so
long as such  continuance  is  specifically  approved  at least  annually by the
Fund's Board of Trustees or by vote of a majority of the outstanding  shares. In
either case, the terms of the Advisory Agreement and continuance thereof must be
approved  by the vote of a  majority  of  Independent  Trustees  in  person at a
meeting  called  for the  purpose  of  voting  on such  approval.  The  Advisory
Agreement may be terminated,  without penalty, on 60 days' written notice by the
Fund or Keystone or may be terminated by a vote of the Fund's shareholders.  The
Agreement will terminate automatically upon its assignment.

- --------------------------------------------------------------------------------
                             PRINCIPAL UNDERWRITER
- --------------------------------------------------------------------------------

         The Fund has  entered  into a  Principal  Underwriting  Agreement  (the
"Principal   Underwriting   Agreement")  with  the  Principal   Underwriter,   a
wholly-owned subsidiary of Keystone.

         The Principal Underwriter,  as agent, currently has the right to obtain
subscriptions for and to sell shares of the Fund to the public. In so doing, the
Principal   Underwriter  may  retain  and  employ   representatives  to  promote
distribution  of the shares  and may  obtain  orders  from  brokers,  dealers or
others,  acting as  principals,  for sales of  shares.  No such  representative,
dealer or broker has any  authority to act as agent for the Fund.  The Principal
Underwriter  has not  undertaken to buy or to find  purchasers  for any specific
number of shares.  The Principal  Underwriter may receive payments from the Fund
pursuant to the Fund's Distribution Plans.

         All subscriptions and sales of shares by the Principal  Underwriter are
at the offering  price of the shares,  such price being in  accordance  with the
provisions of the Fund's Declaration of Trust,  By-Laws,  the current prospectus
and statement of additional information. All orders are subject to acceptance by
the Fund, and the Fund reserves the right, in its sole discretion, to reject any
order  received.  Under the Principal  Underwriting  Agreement,  the Fund is not
liable to anyone for failure to accept any order.

         The Fund has agreed under the Principal  Underwriting  Agreement to pay
all expenses in connection  with  registration of its shares with the Commission
as well as  auditing  and filing fees in  connection  with  registration  of its
shares  under the various  state  "blue-sky"  laws.  The  Principal  Underwriter
assumes the cost of sales literature and preparation of prospectuses  used by it
and certain other expenses.

         From time to time, if in the Principal  Underwriter's judgment it could
benefit  the  sales  of  Fund  shares,  the  Principal  Underwriter  may use its
discretion in providing to selected  dealers  promotional  materials and selling
aids,  including,  but not limited to, personal computers,  related software and
Fund data files.

         The  Principal  Underwriter  has agreed that it will,  in all respects,
duly  conform  with all state and  federal  laws  applicable  to the sale of the
shares and will  indemnify and hold  harmless the Fund,  and each person who has
been, is or may be a Trustee or officer of the Fund, against expenses reasonably
incurred by any of them in connection  with any claim or in connection  with any
action,  suit or  proceeding to which any of them may be a party that arises out
of or is alleged to arise out of any  misrepresentation  or  omission to state a
material fact on the part of the Principal  Underwriter  or any other person for
whose  acts  the  Principal  Underwriter  is  responsible  or is  alleged  to be
responsible, unless such misrepresentation or omission was made in reliance upon
written information furnished by the Fund.

         The Principal  Underwriting  Agreement will remain in effect as long as
its terms and continuance  are approved by a majority of the Fund's  Independent
Trustees  at least  annually  at a meeting  called for that  purpose  and if its
continuance is approved annually by vote of a majority of Trustees or by vote of
a majority of the outstanding shares.

         The  Principal  Underwriting  Agreement  may  be  terminated,   without
penalty, on 60 days' written notice by the Fund's Board of Trustees or by a vote
of a majority of outstanding shares. The Principal  Underwriting  Agreement will
terminate  automatically  upon its  "assignment"  as that term is defined in the
1940 Act.

                              DECLARATION OF TRUST
- --------------------------------------------------------------------------------

MASSACHUSETTS BUSINESS TRUST

         The Fund is  organized as a  Massachusetts  business  trust.  Under its
Declaration  of Trust,  the Fund is  authorized  to issue  more than one  series
(portfolio)  and may divide any series  into more than one class of shares.  The
Portfolio  is  currently  the only  series  the Fund  issues  and the  Portfolio
currently  issues  three  classes  of  shares.  The  Fund  is the  successor  to
International  Heritage Fund,  which was organized as a  Massachusetts  business
trust on September 5, 1986, and Keystone  America Global Income Fund,  which was
formed on April 19,  1989.  The Fund is similar in most  respects  to a business
corporation.  The  principal  distinction  between  the Fund  and a  corporation
relates to shareholder  liability as described  below. A copy of the Declaration
of Trust is filed as an exhibit to the Fund's Registration  Statement,  of which
this statement of additional information is a part. This summary is qualified in
its entirety by reference to the  Declaration  of Trust.  On July 27, 1993,  the
Fund's  shareholders  approved a restatement of the entire  Declaration of Trust
(the "Restatement"). The purpose of the Restatement is to authorize the issuance
of additional classes of shares. The Restatement also omits provisions which are
reiterations  of  statutes,   rules  and  regulations  or  which  are  otherwise
unnecessary  and  expands  certain  provisions  for  clarification  or  ease  of
administration.

DESCRIPTION OF SHARES

         The Declaration of Trust authorizes the issuance of an unlimited number
of shares of beneficial  interest of classes of shares, each of which represents
an equal proportionate interest in the Fund with each other share of that class.
Shares are entitled upon liquidation of the Fund to a pro rata share of the Fund
based on the relative net assets of each class.  Shareholders have no preemptive
or conversion rights. Shares are redeemable,  transferable and freely assignable
as  collateral.  Shareholders  representing  10% or more of the Fund may, as set
forth in the Declaration of Trust, call meetings for any purpose,  including the
purpose of voting on removal of one or more Trustees.

SHAREHOLDER LIABILITY

         Pursuant  to  certain  decisions  of  the  Supreme  Judicial  Court  of
Massachusetts, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held personally liable as partners for the obligations of the
trust. Even if, however, the Fund were held to be a partnership, the possibility
of the  shareholders  incurring  financial  loss for that reason  appears remote
because (1) the Fund's  Declaration of Trust  contains an express  disclaimer of
shareholder  liability for  obligations  of the Fund and requires that notice of
such  disclaimer be given in each  agreement,  obligation or instrument  entered
into or executed by the Fund or the Trustees;  and (2) the  Declaration of Trust
provides for indemnification out of the Fund's property for any shareholder held
personally liable for the obligations of the Fund. The Declaration of Trust also
provides that the Fund will, upon request,  assume the defense of any claim made
against any  shareholder  of the Fund for any act or  obligation of the Fund and
satisfy any judgment thereon from the assets of the Fund.

VOTING RIGHTS

         Under the  terms of the  Declaration  of Trust,  the Fund does not hold
annual  meetings.  However,  at  meetings  called for the  initial  election  of
Trustees  or to  consider  other  matters,  shares are  entitled to one vote per
share.  Classes of shares of the Fund have equal voting  rights except that each
class of shares has  exclusive  voting  rights  with  respect to its  respective
Distribution  Plan.  No amendment may be made to the  Declaration  of Trust that
adversely  affects any class of shares without the approval of a majority of the
shares of that class. Shares have non-cumulative voting rights, which means that
the holders of more than 50% of the shares  voting for the  election of Trustees
can elect 100% of the  Trustees  to be elected at a meeting  and, in such event,
the holders of the  remaining  50% or less of the shares voting will not be able
to elect any Trustees.

         After the initial meeting as described  above,  no further  meetings of
shareholders for the purpose of electing  Trustees will be held, unless required
by law,  until such time as less than a majority of the Trustees  holding office
have been elected by  shareholders,  at which time the  Trustees  then in office
will call a shareholders' meeting for the election of Trustees.

         Except as set forth above,  the Trustees  shall continue to hold office
indefinitely,  unless  otherwise  required  by law,  and may  appoint  successor
Trustees. A Trustee may be removed from or cease to hold office (as the case may
be) (1) at any time by two-thirds vote of the remaining Trustees;  (2) when such
Trustee  becomes  mentally  or  physically  incapacitated;  or (3) at a  special
meeting of  shareholders by a two-thirds  vote of the  outstanding  shares.  Any
Trustee may voluntarily resign from office.

LIMITATION OF TRUSTEES' LIABILITY

         The  Declaration  of Trust provides that a Trustee shall be liable only
for his own willful  defaults and, if reasonable  care has been exercised in the
selection of officers,  agents,  employees or investment advisers,  shall not be
liable for any neglect or wrongdoing of any such person; provided, however, that
nothing  in the  Declaration  of Trust  shall  protect  a  Trustee  against  any
liability for his willful  misfeasance,  bad faith, gross negligence or reckless
disregard of his duties.

         The Trustees have absolute and  exclusive  control over the  management
and  disposition of all assets of the Fund and may perform such acts as in their
sole  judgment  and  discretion  are  necessary  and proper for  conducting  the
business and affairs of the Fund or promoting  the interests of the Fund and the
shareholders

- --------------------------------------------------------------------------------
                 STANDARDIZED TOTAL RETURN AND YIELD QUOTATIONS
- --------------------------------------------------------------------------------

         Total  return  quotations  for a class of shares of a Portfolio  of the
Fund as they may appear from time to time in  advertisements  are  calculated by
finding the average  annual  compounded  rates of return over one,  five and ten
year  periods,  or the time  periods  for which  such  class of shares  has been
effective, whichever is relevant, on a hypothetical $1,000 investment that would
equate the initial amount invested in the class to the ending  redeemable value.
All dividends and distributions are added to the initial investment, the maximum
sales load deducted and all recurring fees charged to all  shareholder  accounts
are deducted.  The ending redeemable value assumes a complete  redemption at the
end of the relevant periods.

         The Portfolio's  Class A total return for the one and five year periods
ended October 31, 1994 were  (11.15)% and 36.13%,  respectively  (including  any
applicable  sales charge).  The Portfolio's  Class A total return for the period
January 9, 1987  (commencement  of  operations)  to October  31, 1994 was 57.93%
(including any  applicable  sales charge).  The  Portfolio's  Class A compounded
average  rate  of  return  for the  period  January  9,  1987  (commencement  of
operations)  to October  31,  1994 was 6.03%  (including  any  applicable  sales
charge).  The Portfolio's Class A compounded average rate of return for the five
year period ended October 31, 1994 was 6.36%  (including  any  applicable  sales
charge).  The total  returns  for Class B and Class C of the  Portfolio  for the
period August 2, 1993 (date of initial public offering) through October 31, 1994
were (9.83)% and (8.48)%,  respectively (including any applicable sales charge).
The total return figures do not reflect expense  subsidizations by International
Heritage  Corp. or Keystone,  the  Portfolio's  advisers  during these  periods.
Effective April 19, 1989,  Keystone became investment  adviser to the Portfolio.
Total return figures are included for historical purposes.

         Current  yield  quotations  as they  may  appear  from  time to time in
advertisements will consist of a quotation based on a 30-day period ended on the
date of the most recent balance sheet of the Portfolio, computed by dividing the
net investment income per share earned during the period by the maximum offering
price per share on the last day of the base period. The Portfolio presently does
not intend to advertise current yield.

                                    APPENDIX



                            MONEY MARKET INSTRUMENTS

         Money market  securities are instruments  with remaining  maturities of
one year or less such as bank  certificates  of deposit,  bankers'  acceptances,
commercial paper (including  variable rate master demand notes), and obligations
issued or guaranteed by the United States ("U.S.")  Government,  its agencies or
instrumentalities, some of which may be subject to repurchase agreements.

Commercial Paper

         Commercial paper,  including commercial paper of foreign issuers,  will
consist  of  issues  rated  at the time of  purchase  A-1 by  Standard  & Poor's
Corporation ("S&P"), or Prime-1 by Moody's Investors Service, Inc., ("Moody's");
or, if not rated,  will be issued by  companies  that have an  outstanding  debt
issue rated at the time of purchase Aaa, Aa or A by Moody's,  or AAA, AA or A by
S&P, or will be determined by Keystone to be of comparable quality.

A.       S&P Ratings

         An  S&P  commercial  paper  rating  is  a  current  assessment  of  the
likelihood of timely payment of debt having an original maturity of no more than
365 days.  Ratings are graded  into four  categories,  ranging  from "A" for the
highest  quality  obligations  to "D" for the  lowest.  The top  category  is as
follows:

         1 A: Issues  assigned  this  highest  rating are regarded as having the
greatest  capacity for timely  payment.  Issues in this category are  delineated
with the numbers 1, 2 and 3 to indicate the relative degree of safety.

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

B.       Moody's Ratings

         The  term  "commercial  paper"  as used  by  Moody's  means  promissory
obligations  not having an original  maturity in excess of nine months.  Moody's
commercial  paper  ratings  are  opinions  of the  ability  of  issuers to repay
punctually  promissory  obligations not having an original maturity in excess of
nine months. Moody's

<PAGE>


                                                                             A-2

employs the following  designation,  judged to be investment  grade, to indicate
the relative repayment capacity of rated issuers.

1. The  rating  Prime-1 is the  highest  commercial  paper  rating  assigned  by
Moody's.  Issuers rated Prime-1 (or related supporting  institutions) are deemed
to have a superior capacity for repayment of short term promissory  obligations.
Repayment  capacity of Prime- 1 issuers is normally  evidenced by the  following
characteristics:

         (1)      leading market positions in well-established industries;
         (2)      high rates of return on funds employed;
         (3)      conservative capitalization structures with moderate
                  reliance on debt and ample asset protection;
         (4)      broad margins in earnings coverage of fixed financial
                  charges and high internal cash generation; and
         (5)      well established access to a range of financial markets
                  and assured sources of alternate liquidity.

         In assigning  ratings to issuers whose commercial paper obligations are
supported by the credit of another  entity or entities,  Moody's  evaluates  the
financial strength of the affiliated  corporations,  commercial banks, insurance
companies,  foreign governments or other entities, but only as one factor in the
total rating assessment.

U.S. Certificates of Deposit

         U.S.  certificates  of deposit are  receipts  issued by a U.S.  bank in
exchange for the deposit of funds. The issuer agrees to pay the amount deposited
plus  interest  to the  bearer  of the  receipt  on the  date  specified  on the
certificate. The certificate usually can be traded in the secondary market prior
to maturity.

         U.S.   Certificates  of  deposit  will  be  limited  to  U.S.   dollar-
denominated  certificates of U.S. banks,  including their branches abroad,  that
are  members of the Federal  Reserve  System or the  Federal  Deposit  Insurance
Corporation,  and of U.S.  branches of foreign  banks,  each of which have total
deposits at the time of purchase in excess of $1 billion.

United States Government Securities

         Securities  issued  or  guaranteed  by the U.S.  government  include  a
variety  of  Treasury  securities  that  differ  only in their  interest  rates,
maturities  and  dates of  issuance  and  securities  issued  by the  Government
National Mortgage  Association  ("GNMA").  Treasury bills have maturities of one
year or less.  Treasury  notes have  maturities of one to ten years and Treasury
bonds  generally  have  maturities  of  greater  than  ten  years at the date of
issuance. GNMA securities include GNMA mortgage pass-through certificates.  Such
securities are supported by the full faith and credit of the U.S.



<PAGE>


                                                                             A-3

         Securities  issued  or  guaranteed  by  U.S.   government  agencies  or
instrumentalities include securities issued or guaranteed by the Federal Housing
Administration,  Farmers Home  Administration,  Export-Import Bank of the United
States, Small Business Administration,  General Services Administration, Central
Bank  for  Cooperatives,   Federal  Home  Loan  Banks,   Federal  Loan  Mortgage
Corporation,  Federal  Intermediate Credit Banks,  Federal Land Banks,  Maritime
Administration,  The Tennessee  Valley  Authority,  District of Columbia  Armory
Board and Federal National Mortgage Association.

         Some  obligations of U.S.  government  agencies and  instrumentalities,
such as securities of Federal Home Loan Banks, are supported by the right of the
issuer to borrow from the Treasury.  Others, such as bonds issued by the Federal
National Mortgage Association, a private corporation,  are supported only by the
credit of the  instrumentality.  Because  the United  States  government  is not
obligated  by law to provide  support to an  instrumentality  it  sponsors,  the
Portfolio will invest in the securities issued by such an  instrumentality  only
when Keystone  determines  under standards  established by the Board of Trustees
that the  credit  risk with  respect  to the  instrumentality  does not make its
securities  unsuitable  investments.  While  the  Portfolio  may  invest in such
instruments,  United States government  securities do not include  international
agencies  or  instrumentalities  in which  the  United  States  government,  its
agencies  or  instrumentalities  participate,  such  as the  World  Bank,  Asian
Development Bank or the Interamerican Development Bank, or issues insured by the
Federal Deposit Insurance Corporation.

                             CORPORATE BOND RATINGS

S&P Corporate Bond Ratings

         An  S&P  corporate   bond  rating  is  a  current   assessment  of  the
creditworthiness  of an  obligor,  including  obligors  outside  the U.S.,  with
respect to a specific  obligation.  This assessment may take into  consideration
obligors such as guarantors,  insurers, or lessees.  Ratings of foreign obligors
do not take into  account  currency  exchange  and  related  uncertainties.  The
ratings are based on current information  furnished by the issuer or obtained by
S&P from other sources it considers reliable.

         The  ratings  are  based,   in  varying   degrees,   on  the  following
considerations:

         a.  Likelihood of default - capacity and  willingness of the obligor as
to the timely payment of interest and repayment of principal in accordance  with
the terms of the obligation;

         b.  Nature of and provisions of the obligation; and



<PAGE>


                                                                             A-4

         c.  Protection  afforded by and relative  position of the obligation in
the event of bankruptcy,  reorganization  or other arrangement under the laws of
bankruptcy and other laws affecting creditors' rights.

         PLUS (+) OR MINUS (-): To provide more detailed  indications  of credit
quality,  ratings  from "AA" to "A" may be modified by the addition of a plus or
minus sign to show relative standing within the major rating categories.

         Bond ratings are as follows:

         1.  AAA - Debt  rated  AAA  has the  highest  rating  assigned  by S&P.
Capacity to pay interest and repay principal is extremely strong.

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

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

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

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

         6.  CI - The rating CI is reserved for income bonds on which
no interest is being paid.

         7.  D - Debt rated D is in default and payment of interest
and/or repayment of principal is in arrears.

B.       Moody's Corporate Bond Ratings

         Moody's ratings are as follows:



<PAGE>


                                                                             A-5

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

         2. Aa - Bonds that are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds.  They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long term risks appear somewhat larger than in Aaa securities.

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

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

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

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

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

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

         Moody's applies numerical modifiers,  1, 2 and 3 in each generic rating
classification  from Aa  through B in its  corporate  bond  rating  system.  The
modifier 1 indicates  that the  security  ranks in the higher end of its generic
rating category;  the modifier 2 indicates a mid-range ranking; and the modifier
3  indicates  that  the  issue  ranks in the  lower  end of its  generic  rating
category.

                       COMMON AND PREFERRED STOCK RATINGS

S&P's Earnings and Dividend Rankings for Common Stocks

         Because the investment process involves  assessment of various factors,
such as product and industry position, corporate resources and financial policy,
with results that make some common stocks more highly esteemed than others,  S&P
believes  that  earnings  and  dividend  performance  is the end  result  of the
interplay  of these  factors  and that,  over the long run,  the  record of this
performance  has a  considerable  bearing on  relative  quality.  S&P  rankings,
however, do not reflect all of the factors, tangible or intangible, that bear on
stock quality.

         Growth and  stability of earnings and dividends are deemed key elements
in  establishing  S&P earnings and dividend  rankings for common  stocks,  which
capsulize the nature of this record in a single symbol.

         S&P has  established a  computerized  scoring system based on per share
earnings and dividend records of the most recent ten years, a period deemed long
enough to measure a company's performance under varying economic conditions. S&P
measures growth,  stability  within the trend line and cyclicality.  The ranking
system also makes  allowances  for company  size,  since  large  companies  have
certain inherent  advantages over small ones. From these scores for earnings and
dividends are determined.

         The final  score for each stock is  measured  against a scoring  matrix
determined by analysis of the scores of a large and representative  sample which
is reviewed and sometimes modified with the following ladder of rankings:

<TABLE>
<S>     <C>                        <C>     <C>                                 <C>     <C> 
 A+      Highest                    B+      Average                             C       Lowest
 A       High                       B       Below Average                       D       In Reorganization
 A-      Above Average              B-      Lower
</TABLE>

         S&P believes  its  rankings  are not a forecast of future  market price
performance, but are basically an appraisal of past

                                                                             A-7

performance of earnings and dividends, and relative current standing.

Moody's Common Stock Rankings

         Moody's presents a concise  statement of the important  characteristics
of a company and an evaluation of the grade (quality) of its common stock.  Data
presented  includes:  (a) capsule stock information which reveals short and long
term growth and yield  afforded  by the  indicated  dividend,  based on a recent
price;  (b) a long term price chart which shows  patterns of monthly stock price
movements and monthly trading  volumes;  (c) a breakdown of a company's  capital
account  which aids in  determining  the  degree of  conservatism  or  financial
leverage in a company's balance sheet; (d) interim earnings for the current year
to date,  plus three  previous  years;  (e)  dividend  information;  (f) company
background;  (g) recent corporate  developments;  (h) prospects for a company in
the  immediate  future  and the next few years;  and (i) a ten year  comparative
statistical analysis.

         This information  provides investors with information on what a company
does, how it has performed in the past, how it is performing  currently and what
its future performance prospects appear to be.

         These  characteristics  are then evaluated and result in a grading,  or
indication  of  quality.  The grade is based on an  analysis  of each  company's
financial strength, stability of earnings and record of dividend payments. Other
considerations include conservativeness of capitalization,  depth and caliber of
management,  accounting  practices,   technological  capabilities  and  industry
position. Evaluation is represented by the following grades:

         (1)  High Grade
         (2)  Investment Grade
         (3)  Medium Grade
         (4)  Speculative Grade

Moody's Preferred Stock Ratings

         Preferred stock ratings and their definitions are as follows:

         1. aaa: An issue that is rated "aaa" is  considered to be a top-quality
preferred stock.  This rating indicates good asset protection and the least risk
of dividend impairment within the universe of preferred stocks.
         2. aa: An issue that is rated "aa" is considered a high-grade preferred
stock. This rating indicates that there is a reasonable  assurance that earnings
and asset  protection will remain  relatively well maintained in the foreseeable
future.


<PAGE>


                                                                             A-8


         3. a: An issue that is rated "a" is  considered  to be an  upper-medium
grade preferred stock. While risks are judged to be somewhat greater than in the
"aaa" and "aa" classification,  earnings and asset protection are, nevertheless,
expected to be maintained at adequate levels.

         4. baa: An issue that is rated "baa" is considered to be a medium-grade
preferred stock, neither highly protected nor poorly secured. Earnings and asset
protection  appear  adequate at present but may be  questionable  over any great
length of time.

         5. ba: An issue that is rated "ba" is  considered  to have  speculative
elements and its future  cannot be considered  well assured.  Earnings and asset
protection may be very moderate and not well safeguarded during adverse periods.
Uncertainty of position characterizes preferred stocks in this class.

         6. b: An issue that is rated "b" generally lacks the characteristics of
a desirable investment.  Assurance of dividend payments and maintenance of other
terms of the issue over any long period of time may be small.

         7. caa:  An issue  that is rated  "caa" is likely to be in  arrears  on
dividend  payments.  This rating  designation  does not purport to indicate  the
future status of payments.

         8. ca: An issue that is rated "ca" is  speculative in a high degree and
is likely to be in arrears on  dividends  with  little  likelihood  of  eventual
payments.

         9. c: This is the lowest rated class of preferred or preference  stock.
Issues so rated can be  regarded  as having  extremely  poor  prospects  of ever
attaining any real investment standing.

         Moody's  applies  numerical  modifiers  1,  2  and  3  in  each  rating
classification:  the modifier 1 indicates  that the security ranks in the higher
end of its  generic  rating  category;  the  modifier 2  indicates  a  mid-range
ranking;  and the modifier 3 indicates  that the issue ranks in the lower end of
its generic rating category.

                              OPTIONS TRANSACTIONS

Writing Covered Options

         The  Portfolio  writes only  covered  options.  Options  written by the
Portfolio will normally have  expiraton  dates of not more than nine months from
the date written.  The exercise price of the options may be below,  equal to, or
above the current  market values of the  underlying  securities at the times the
options are written.



<PAGE>


                                                                             A-9

         Unless the option has been  exercised,  the  Portfolio may close out an
option it has written by effecting a closing  purchase  transaction,  whereby it
purchases an option  covering the same  underlying  security and having the same
exercise  price and  expiration  date ("of the same  series")  as the one it has
written.  If the Portfolio desires to sell a particular security on which it has
written a call option, it will effect a closing purchase transaction prior to or
concurrently  with the sale of the  security.  If the Portfolio is able to enter
into a closing  purchase  transaction,  the Portfolio  will realize a profit (or
loss) from such  transaction  if the cost of such  transaction is less (or more)
than the premium received from the writing of the option.

         An option position may be closed out only in a secondary  market for an
option of the same series.  Although the  Portfolio  will  generally  write only
those options for which there appears to be an active secondary market, there is
no assurance that a liquid secondary market will exist for any particular option
at any particular  time, and for some options no secondary  market may exist. In
such  event it might  not be  possible  to  effect a  closing  transaction  in a
particular option. If the Portfolio as a covered call option writer is unable to
effect  a  closing  purchase  transaction,  it will  not be  able  to  sell  the
underlying  securities  until the option  expires or it delivers the  underlying
securities upon exercise.

         Because  the  Portfolio  intends to qualify as a  regulated  investment
company under the Internal  Revenue Code,  the extent to which the Portfolio may
write  covered call  options and enter into  so-called  "straddle"  transactions
involving put and call options may be limited.

         Many options are traded on  registered  securities  exchanges.  Options
traded on such exchanges are issued by the Options Clearing Corporation ("OCC"),
a clearing  corporation  which  assumes  responsibility  for the  completion  of
options transactions.

Option Writing and Related Risks

         The Portfolio may write covered call and put options with respect to up
to 25% of its net assets.  A call option  gives the  purchaser of the option the
right to buy, and the writer the obligation to sell, the underlying  security at
the exercise price during the option period.  Conversely, a put option gives the
purchaser  the  right  to  sell,  and the  writer  the  obligation  to buy,  the
underlying security at the exercise price during the option period.

         So long as the  obligation of the writer  continues,  the writer may be
assigned an exercise  notice by the  broker-dealer  through  whom the option was
sold. The exercise notice would require the writer to deliver,  in the case of a
call, or take delivery of, in


<PAGE>


                                                                            A-10

the case of a put,  the  underlying  security  against  payment of the  exercise
price.  This obligation  terminates  upon  expiration of the option,  or at such
earlier time as the writer effects a closing purchase  transaction by purchasing
an option of the same series as the one previously sold. Once an option has been
exercised,  the  writer  may not  execute a closing  purchase  transaction.  For
options traded on national  securities  exchanges  ("Exchanges"),  to secure the
obligation to deliver the underlying  security in the case of a call option, the
writer of the option is required to deposit in escrow the underlying security or
other assets in accordance with the rules of the OCC, an institution  created to
interpose  itself  between buyers and sellers of options.  Technically,  the OCC
assumes the order side of every  purchase  and sale  transaction  on an Exchange
and, by doing so, gives its guarantee to the transaction.

         The principal  reason for writing options on a securities  portfolio is
to attempt to realize,  through the receipt of premiums,  a greater  return than
would be realized on the underlying securities alone. In return for the premium,
the covered call option  writer has given up the  opportunity  for profit from a
price  increase in the  underlying  security above the exercise price so long as
the option  remains  open,  but retains the risk of loss should the price of the
security decline.  Conversely, the put option writer gains a profit, in the form
of a premium,  so long as the price of the underlying security remains above the
exercise  price,  but assumes an obligation to purchase the underlying  security
from the buyer of the put option at the exercise price, even though the price of
the security may fall below the  exercise  price,  at any time during the option
period.  If an option  expires,  the writer realizes a gain in the amount of the
premium.  Such a gain may, in the case of a covered call option,  be offset by a
decline in the market value of the underlying security during the option period.
If a call option is exercised,  the writer realizes a gain or loss from the sale
of the  underlying  security.  If a put option is  exercised,  the  writer  must
fulfill his  obligation  to purchase  the  underlying  security at the  exercise
price,  which  will  usually  exceed  the then  market  value of the  underlying
security.  In addition,  the premium paid for the put effectively  increases the
cost of the underlying  security,  thus reducing the yield  otherwise  available
from such security.

         Because the Portfolio can write only covered  options,  it may at times
be unable to write additional options unless it sells a portion of its portfolio
holdings to obtain new securities  against which it can write options.  This may
result  in higher  portfolio  turnover  and  correspondingly  greater  brokerage
commissions and other transaction costs.

         To the extent that a secondary  market is available the covered  option
writer  may close out  options  it has  written  prior to the  assignment  of an
exercise notice by purchasing,  on a closing purchase transaction,  an option of
the same series as the option


<PAGE>


                                                                            A-11

previously  written.  If the cost of such a closing  purchase,  plus transaction
costs,  is greater than the premium  received upon writing the original  option,
the writer will incur a loss in the transaction.

Purchasing Put and Call Options

         The  Portfolio can close out a put option it has purchased by effecting
a closing sale  transaction;  for  example,  the  Portfolio  may close out a put
option it has purchased by selling a put option. If, however, a secondary market
does  not  exist  at a time the  Portfolio  wishes  to  effect  a  closing  sale
transaction,  the  Portfolio  will have to  exercise  the option to realize  any
profit.  In addition,  in a transaction  in which the Portfolio does not own the
security  underlying  a put  option it has  purchased,  the  Portfolio  would be
required,  in the absence of a secondary  market,  to  purchase  the  underlying
security  before  it could  exercise  the  option.  In each such  instance,  the
Portfolio  would incur  additional  transaction  costs.  The  Portfolio may also
purchase  call  options for the purpose of  offsetting  previously  written call
options of the same series.

         The Portfolio  would normally  purchase call options in anticipation of
an increase in the market value of securities of the type in which the Portfolio
may invest. The purchase of a call option would entitle the Portfolio, in return
for the premium paid,  to purchase  specified  securities  at a specified  price
during the option  period.  The Portfolio  would  ordinarily  realize a gain if,
during the option period,  the value of such securities  exceeded the sum of the
exercise price, the premium paid and transaction costs;  otherwise the Portfolio
would realize a loss on the purchase of the call option.

         The Portfolio would normally  purchase put options in anticipation of a
decline in the market value of securities in its portfolio  ("protective  puts")
or securities of the type in which it is permitted to invest.  The purchase of a
put option would  entitle the  Portfolio,  in exchange for the premium  paid, to
sell specified  securities at a specified  price during the option  period.  The
purchase  of  protective  puts is designed  merely to offset or hedge  against a
decline in the market value of the Portfolio's  securities.  Gains and losses on
the purchase of protective put options would tend to be offset by countervailing
changes in the value of underlying portfolio securities. Put options may also be
purchased by the Portfolio for the purpose of  affirmatively  benefitting from a
decline  in the  price of  securities  that  the  Portfolio  does  not own.  The
Portfolio  would  ordinarily  realize a gain if, during the option  period,  the
value  of  the  underlying   securities   decreased  below  the  exercise  price
sufficiently to cover the premium and transaction costs; otherwise the Portfolio
would realize a loss on the purchase of the put option.



<PAGE>


                                                                            A-12

         The Portfolio  may purchase put and call options on securities  indices
for the same  purposes  as the  purchase  of options on  securities.  Options on
securities  indices  are  similar  to  options on  securities,  except  that the
exercise of securities index options requires cash payments and does not involve
the actual purchase or sale of securities. In addition, securities index options
are designed to reflect price  fluctuations  in a group of securities or segment
of the securities market rather than price fluctuations in a single security.

Options Trading Markets

         Options  in which the  Portfolio  will  trade are  generally  listed on
Exchanges.  Exchanges on which such  options  currently  are traded  include the
Chicago  Board  Options  Exchange  and  the New  York,  American,  Pacific,  and
Philadelphia  Stock  Exchanges.  Options on some securities may not be listed on
any Exchange but traded in the  over-the-counter  market.  Options traded in the
over-the-counter  market involve the  additional  risk that  securities  dealers
participating in such  transactions  would fail to meet their obligations to the
Portfolio.  The use of  options  traded in the  over-the-counter  market  may be
subject to  limitations  imposed by certain  state  securities  authorities.  In
addition to the limits on its use of options discussed herein,  the Portfolio is
subject to the  investment  restrictions  described  in the  prospectus  and the
statement of additional information.

         The staff of the Commission  currently is of the view that the premiums
that the  Portfolio  pays for the purchase of unlisted  options and the value of
securities  used  to  cover  unlisted  options  written  by  the  Portfolio  are
considered  to be invested in illiquid  securities  or assets for the purpose of
calculating  whether  the  Portfolio  is  in  compliance  with  its  fundamental
investment restriction  prohibiting it from investing more than 10% of its total
assets  (taken at  current  value) in any  combination  of  illiquid  assets and
securities.   The  Portfolio  intends  to  request  that  the  Commission  staff
reconsider its current view. It is the intention of the Portfolio to comply with
the staff's current position and the outcome of such reconsideration.

Special Considerations Applicable to Options

         On Treasury Bonds and Notes.  Because trading interest in U.S. Treasury
bonds and  notes  tends to center on the most  recently  auctioned  issues,  new
series of options with  expirations  to replace  expiring  options on particular
issues will not be introduced indefinitely.  Instead, the expirations introduced
at the  commencement of options trading on a particular issue will be allowed to
run  their  course,  with the  possible  addition  of a  limited  number  of new
expirations as the original ones expire. Options trading on each series of bonds
or notes will thus be phased out as new  options  are listed on the more  recent
issues, and


<PAGE>


                                                                            A-13

a full range of  expiration  dates will not  ordinarily  be available  for every
series on which options are traded.

         On Treasury Bills.  Because the deliverable U.S.  Treasury bill changes
from week to week,  writers of U.S. Treasury bill call options cannot provide in
advance for their  potential  exercise  settlement  obligations by acquiring and
holding the underlying security. However, if the Portfolio holds a long position
in U.S.  Treasury  bills with a principal  amount  corrresponding  to the option
contract size, the Portfolio may be hedged from a risk standpoint.  In addition,
to  ensure  that it can meet its open  option  obligations  the  Portfolio  will
maintain  in a  segregated  account  with the  Fund's  Custodian  liquid  assets
maturing  no later  than those  which  would be  deliverable  in the event of an
assignment of an exercise notice.

         On GNMA  Certificates.  Options on GNMA  certificates are not currently
traded on any  Exchange.  However,  the  Portfolio  may  purchase and write such
options in the over the counter market or, should they commence trading,  on any
Exchange.

         Since the remaining  principal  balance of GNMA  certificates  declines
each month as a result of mortgage  payments,  the  Portfolio,  as a writer of a
covered GNMA call holding GNMA  certificates  as "cover" to satisfy its delivery
obligation in the event of assignment of an exercise  notice,  may find that its
GNMA  certificates no longer have a sufficient  remaining  principal balance for
this  purpose.  Should  this  occur,  the  Portfolio  will  enter into a closing
purchase transaction or will purchase additional GNMA certificates from the same
pool (if  obtainable) or  replacement  GNMA  certificates  in the cash market in
order to remain covered.

         A GNMA certificate held by the Portfolio to cover an option position in
any but the nearest expiration month may cease to represent cover for the option
in the  event of a  decline  in the GNMA  coupon  rate at which  new  pools  are
originated  under the FHA/VA loan  ceiling in effect at any given  time.  Should
this occur,  the Portfolio  will no longer be covered,  and the  Portfolio  will
either enter into a closing purchase transaction or replace the GNMA certificate
with a  certificate  which  represents  cover.  When the  Portfolio  closes  its
position or replaces the GNMA certificate,  it may realize an unanticipated loss
and incur transaction costs.

         Risks  Pertaining to the Secondary  Market.  An option  position may be
closed out only in a secondary market for an option of the same series. Although
the  Portfolio  will  generally  purchase or write only those  options for which
there appears to be an active  secondary  market,  there is no assurance  that a
liquid secondary  market will exist for any particular  option at any particular
time,  and for some options no  secondary  market may exist.  In such event,  it
might not be possible to effect closing transactions in particular options, with
the result that the Portfolio would have


<PAGE>


                                                                            A-14

to  exercise  its  options  in order to  realize  any  profit  and  might  incur
transaction  costs in connection  therewith.  If the Portfolio as a covered call
option writer is unable to effect a closing purchase  transaction in a secondary
market,  it will not be able to sell the  underlying  security  until the option
expires or it delivers the underlying security upon exercise.

         Reasons  for the  absence  of a liquid  secondary  market  include  the
following:   (i)  insufficient   trading  interest  in  certain  options;   (ii)
restrictions imposed on transactions;  (iii) trading halts, suspensions or other
restrictions  imposed with respect to particular classes or series of options or
underlying securities; (iv) interruption of the normal operations on an Exchange
or by a broker;  (v) inadequacy of the  facilities of an Exchange,  the OCC or a
broker to handle  current  trading  volume;  or (vi) a  decision  by one or more
Exchanges  or a broker to  discontinue  the trading of options (or a  particular
class or series of options),  in which event the secondary  market in that class
or series of options would cease to exist, although outstanding options that had
been issued as a result of trades would generally  continue to be exercisable in
accordance with their terms.

         The hours of trading for options on U.S. government  securities may not
conform to the hours during which the underlying  securities are traded.  To the
extent that the option  markets  close  before the  markets  for the  underlying
securities,  significant  price  and  rate  movements  can  take  place  in  the
underlying markets that cannot be reflected in the option markets.

               FUTURES CONTRACTS AND RELATED OPTIONS TRANSACTIONS

         The  Portfolio  intends  to enter  into  currency  and other  financial
futures contracts as a hedge against changes in prevailing levels of interest or
currency exchange rates to seek relative stability of principal and to establish
more  definitely  the  effective  return on  securities  held or  intended to be
acquired  by the  Portfolio  or as a hedge  against  changes  in the  prices  of
securities  or  currencies  held  by  the  Portfolio  or to be  acquired  by the
Portfolio.  The  Portfolio's  hedging may include  sales of futures as an offset
against the effect of expected  increases in interest or currency exchange rates
or securities prices and purchases of futures as an offset against the effect of
expected declines in interest or currency exchange rates.

         The  Portfolio  intends  to engage  in  options  transactions  that are
related to currency and other financial  futures  contracts for hedging purposes
and in connection with the hedging strategies described above.

         Although techniques other than sales and purchases of futures contracts
and  related  options  transactions  could  be used to  reduce  the  Portfolio's
exposure to interest rate and/or market


<PAGE>


                                                                            A-15

fluctuations,  the Portfolio may be able to hedge its exposure more  effectively
and perhaps at a lower cost through using futures  contracts and related options
transactions.  While  the  Portfolio  does not  intend to take  delivery  of the
instruments underlying futures contracts it holds, the Portfolio does not intend
to engage in such futures contracts for speculation.

Futures Contracts

         Futures  contracts are  transactions in the commodities  markets rather
than in the securities  markets. A futures contract creates an obligation by the
seller to deliver to the buyer the  commodity  specified  in the  contract  at a
specified  future time for a specified  price.  The futures  contract creates an
obligation  by the buyer to accept  delivery  from the  seller of the  commodity
specified at the specified future time for the specified  price. In contrast,  a
spot transaction  creates an immediate  obligation for the seller to deliver and
the buyer to accept delivery of and pay for an identified commodity. In general,
futures contracts involve  transactions in fungible goods such as wheat,  coffee
and  soybeans.  However,  in the last  decade an  increasing  number of  futures
contracts have been developed that specify currencies,  financial instruments or
financially based indexes as the underlying commodity.

         U.S. futures  contracts are traded only on national  futures  exchanges
and are  standardized as to maturity date and underlying  financial  instrument.
The principal  financial futures exchanges in the United States are The Board of
Trade of the City of Chicago, the Chicago Mercantile Exchange, the International
Monetary Market (a division of the Chicago  Mercantile  Exchange),  the New York

Options on Currency and Other Financial Futures

         The Portfolio  intends to purchase call and put options on currency and
other financial futures contracts and sell such options. Options on currency and
other financial  futures  contracts are similar to options on stocks except that
an option on a currency or other financial  futures contract gives the purchaser
the right,  in return for the  premium  paid,  to assume a position in a futures
contract (a long  position  if the option is a call and a short  position if the
option is a put) rather than to purchase or


<PAGE>


                                                                            A-16

sell stock,  currency or other  financial  instruments  at a specified  exercise
price at any time during the period of the option.  Upon exercise of the option,
the  delivery of the futures  position by the writer of the option to the holder
of the option will be accompanied by delivery of the accumulated  balance in the
writer's futures margin account.  This amount represents the amount by which the
market price of the futures contract at exercise exceeds, in the case of a call,
or is less than,  in the case of a put, the exercise  price of the option on the
futures contract. If an option is exercised on the last trading day prior to the
expiration  date of the option,  the  settlement  will be made  entirely in cash
equal to the  difference  between the exercise  price of the option and value of
the futures contract.

         The  Portfolio  intends to use options on currency and other  financial
futures  contracts  in  connection  with hedging  strategies.  In the future the
Portfolio may use such options for other purposes.

Purchase of Put Options on Futures Contracts

         The purchase of protective put options on financial  futures  contracts
is analagous to the purchase of protective puts on individual  stocks,  where an
absolute  level of protection is sought below which no additional  economic loss
would be incurred by the  Portfolio.  Put  options may be  purchased  to hedge a
portfolio of stocks or debt  instruments  or a position in the futures  contract
upon which the put option is based.

Purchase of Call Options on Futures Contracts

         The purchase of call options on currency  and other  financial  futures
contracts   represents  a  means  of  obtaining  temporary  exposure  to  market
appreciation  at limited  risk. It is analogous to the purchase of a call option
on an individual  stock which can be used as a substitute  for a position in the
stock  itself.  Depending  on the  pricing of the option  compared to either the
futures  contract  upon which it is based,  or upon the price of the  underlying
financial  instrument or index itself, the purchase of a call option may be less
risky than the ownership of the interest rate or index based futures contract or
the underlying  securities.  Call options on currency or other financial futures
contracts  may be  purchased  to hedge  against an interest  rate  increase or a
market advance when the Portfolio is not fully invested.

Use of New Investment Techniques Involving Currency and Other
Financial Futures Contracts or Related Options

         The Portfolio may employ new investment  techniques  involving currency
and other financial futures contracts and related options. The Portfolio intends
to take  advantage of new  techniques in these areas which may be developed from
time to time and which are


<PAGE>


                                                                            A-17

consistent with the Portfolio's  investment  objective.  The Portfolio  believes
that no  additional  techniques  have  been  identified  for  employment  by the
Portfolio in the foreseeable future other than those described above.

Limitations on Purchase and Sale of Futures Contracts and Related
Options on Such Futures Contracts

         The  Portfolio  will not enter into a futures  contract if, as a result
thereof,  more than 5% of the Portfolio's total assets (taken at market value at
the time of entering into the contract) would be committed to margin deposits on
such futures contracts and premiums on options futures contracts.

         The Portfolio  intends that its futures  contracts and related  options
transactions  will be entered into for traditional  hedging  purposes.  That is,
futures  contracts  will be sold to  protect  against a decline  in the price of
securities  that the Portfolio  owns or futures  contracts  will be purchased to
protect the Portfolio  against an increase in the price of securities it intends
to purchase.  The Portfolio does not intend to enter into futures  contracts for
speculation.

         In instances involving the purchase or sale of futures contracts by the
Portfolio,  an amount of cash and cash  equivalents  or securities  equal to the
market value of the futures contracts will be deposited in a segregated  account
with the Fund's custodian. In addition, in the case of a purchase, the Portfolio
may be  required  to  make a  deposit  to a  margin  account  with a  Broker  to
collateralize  the  position,  and in the case of a sale,  the  Portfolio may be
required to make daily  deposits to the buyer's  margin  account.  The Portfolio
would  make such  deposits  in order to insure  that the use of such  futures is
unleveraged.

Federal Income Tax Treatment

         For federal income tax purposes, the Portfolio is required to recognize
as income for each taxable year its net  unrealized  gains and losses on futures
contracts as of the end of the year as well as those  actually  realized  during
the year.  Any gain or loss  recognized  with  respect to a futures  contract is
considered to be 60% long term and 40% short term, without regard to the holding
period of the  contract.  In the case of a futures  transaction  classified as a
"mixed  straddle," the  recognition of losses may be deferred to a later taxable
year. The federal income tax treatment of gains or losses from  transactions  in
options on futures is unclear.

         In order for the  Portfolio  to continue to qualify for federal  income
tax  treatment  as a  regulated  investment  company,  at least 90% of its gross
income for a taxable year must be derived from qualifying  income.  Any net gain
realized from the closing out of


<PAGE>


                                                                            A-18

futures  contracts,  for  purposes of the 90%  requirement,  will be  qualifying
income.  In  addition,  gains  realized  on the  sale or  other  disposition  of
securities  held for less than three  months must be limited to less than 30% of
the  Portfolio's  annual gross income.  The 1986 Tax Act added a provision which
effectively  treats both positions in certain  hedging  transactions as a single
transaction for the purpose of the 30% requirement. The provision provides that,
in the case of any "designated  hedge,"  increases and decreases in the value of
positions of the hedge are to be netted for the purposes of the 30% requirement.
However,  in certain  situations,  in order to avoid  realizing  a gain within a
three month period,  the Portfolio may be required to defer the closing out of a
contract beyond the time when it would otherwise be advantageous to do so.

Risks of Futures Contracts

         Currency and other financial  futures contracts prices are volatile and
are  influenced,  among  other  things,  by  changes  in  stock  prices,  market
conditions,  prevailing  interest rates and anticipation of future stock prices,
market movements or interest rate changes,  all of which in turn are affected by
economic  conditions,  such as  government  fiscal  and  monetary  policies  and
actions, and national and international political and economic events.

         At best, the correlation between changes in prices of futures contracts
and of the  securities  being  hedged  can be only  approximate.  The  degree of
imperfection of correlation  depends upon  circumstances,  such as variations in
speculative  market demand for futures  contracts and for securities,  including
technical  influences in futures contracts trading;  and differences between the
securities being hedged and the financial instruments and indexes underlying the
standard futures contracts  available for trading,  in such respects as interest
rate levels,  maturities  and  creditworthiness  of issuers,  or  identities  of
securities  comprising  the  index  and those in the  Portfolio's  portfolio.  A
decision of whether,  when and how to hedge  involves  the exercise of skill and
judgment,  and even a  well-conceived  hedge may be  unsuccessful to some degree
because of market behavior or unexpected interest rate trends.

         Because of the low margin deposits  required,  futures trading involves
an extremely  high degree of  leverage.  As a result,  a relatively  small price
movement in a futures contract may result in immediate and substantial  loss, as
well as gain, to the investor.  For example, if at the time of purchase,  10% of
the value of the futures  contract is deposited as margin, a 10% decrease in the
value  of the  futures  contract  would  result  in a total  loss of the  margin
deposit,  before any deduction for the  transaction  costs,  if the account were
then closed out, and a 15% decrease  would result in a loss equal to 150% of the
original margin deposit. Thus, a


<PAGE>


                                                                            A-19

purchase  or sale of a futures  contract  may  result in losses in excess of the
amount invested in the futures contract. However, the Portfolio would presumably
have  sustained  comparable  losses if,  instead of  entering  into the  futures
contract, it had invested in the underlying financial  instrument.  Furthermore,
in order to be certain that the Portfolio has  sufficient  assets to satisfy its
obligations under a futures contract,  the Portfolio will establish a segregated
account in connection  with its futures  contracts  which will hold cash or cash
equivalents equal in value to the current value of the underlying instruments or
indices less the margins on deposit.

         Most U.S. futures  exchanges limit the amount of fluctuation  permitted
in  futures  contract  prices  during a single  trading  day.  The  daily  limit
establishes  the maximum  amount that the price of a futures  contract  may vary
either  up or down  from the  previous  day's  settlement  price at the end of a
trading  session.  Once the daily limit has been reached in a particular type of
contract,  no trades may be made on that day at a price  beyond that limit.  The
daily limit  governs only price  movement  during a  particular  trading day and
therefore  does not limit  potential  losses  because  the limit may prevent the
liquidation of unfavorable positions.  Futures contract prices have occasionally
moved to the daily limit for several  consecutive trading days with little or no
trading,   thereby  preventing  prompt  liquidation  of  futures  positions  and
subjecting some futures traders to substantial losses.

Risks of Options on Futures Contracts

         In  addition  to the  risks  described  above  for  currency  and other
financial futures contracts, there are several special risks relating to options
on futures  contracts.  The ability to establish and close out positions on such
options will be subject to the development and maintenance of a liquid secondary
market.  There is no assurance that a liquid secondary market will exist for any
particular  option or at any  particular  time.  The Portfolio will not purchase
options on any futures contract unless and until it believes that the market for
such options has developed  sufficiently  that the risks in connection with such
options are not greater than the risks in connection with the futures contracts.
Compared  to the use of  futures  contracts,  the  purchase  of  options on such
futures involves less potential risk to the Portfolio because the maximum amount
at risk is the premium paid for the options (plus transaction  costs).  However,
there may be circumstances when the use of an option on a futures contract would
result in a loss to the  Portfolio,  even  though the use of a futures  contract
would  not,  such as when  there is no  movement  in the  level  of the  futures
contract.

                         FOREIGN CURRENCY TRANSACTIONS

         The Portfolio may invest in  securities  of foreign  issuers.  When the
Portfolio  invests in foreign  securities  they usually will be  denominated  in
foreign  currencies  and the  Portfolio  temporarily  may hold  funds in foreign
currencies.  Thus,  the  Portfolio's  share value will be affected by changes in
exchange rates.

Forward Currency Contracts

         As one way of managing  exchange rate risk, the Portfolio may engage in
forward currency exchange  contracts  (agreements to purchase or sell currencies
at a specified  price and date).  Under the contract,  the exchange rate for the
transaction  (the amount of currency the Portfolio  will deliver or receive when
the contract is completed) is fixed when the Portfolio enters into the contract.
The  Portfolio  usually will enter into these  contracts  to stabilize  the U.S.
dollar value of a security it has agreed to buy or sell.  The Portfolio also may
use these  contracts  to hedge the U.S.  dollar  value of a security  it already
owns,  particularly  if the  Portfolio  expects a  decrease  in the value of the
currency in which the foreign  security is  denominated.  Although the Portfolio
will attempt to benefit from using forward contracts, the success of its hedging
strategy  will depend on  Keystone's  ability to predict  accurately  the future
exchange rates between foreign  currencies and the U.S. dollar. The value of the
Portfolio's  investments  denominated in foreign  currencies  will depend on the
relative strength of those currencies and the U.S. dollar, and the Portfolio may
be  affected  favorably  or  unfavorably  by  changes in the  exchange  rates or
exchange control regulations between foreign currencies and the dollar.  Changes
in foreign  currency  exchange  rates also may affect the value of dividends and
interest  earned,  gains and losses  realized on the sale of securities  and net
investment  income and gains,  if any, to be distributed to  shareholders by the
Portfolio.

Currency Futures Contracts

         Currency  futures  contracts are bilateral  agreements  under which two
parties agree to take or make delivery of a specified  amount of a currency at a
specified  future  time for a  specified  price.  Trading  of  currency  futures
contracts in the United States is regulated under the Commodity  Exchange Act by
the  Commodity  Futures  Trading   Commission   ("CFTC")  and  National  Futures
Association  ("NFA").  Currently  the only  national  futures  exchange on which
currency futures are traded is the International  Monetary Market of the Chicago
Mercantile  Exchange.  Foreign currency futures trading is conducted in the same
manner and subject to the same regulations as trading in interest rate and index
based  futures.  The  Portfolio  intends  to only  engage  in  currency  futures
contracts  for hedging  purposes,  and not for  speculation.  The  Portfolio may
engage in currency futures contracts for other


<PAGE>


                                                                            A-21

purposes if authorized to do so by the Board.  The hedging  strategies that will
be used by the Portfolio in connection with foreign currency  futures  contracts
are similar to those  described  above for  forward  foreign  currency  exchange
contracts.

         Currently  currency  futures  contracts for the British Pound Sterling,
Canadian Dollar, Dutch Guilder, Deutsche Mark, Japanese Yen, Mexican Peso, Swiss
Franc and French  Franc can be purchased  or sold for U.S.  dollars  through the
International  Monetary Market. It is expected that futures contracts trading in
additional  currencies  will be  authorized.  The  standard  contract  sizes are
L125,000 for the Pound, 125,000 for the Guilder,  Mark, Swiss and French Francs,
C$100,000 for the Canadian  Dollar,  Y12,500,000  for the Yen, and 1,000,000 for
the Peso. In contrast to Forward Currency Exchange Contracts which can be traded
at any time,  only four value dates per year are available,  the third Wednesday
of March, June, September and December.

Foreign Currency Options Transactions

         Foreign  currency  options  (as  opposed  to  futures)  are traded in a
variety of currencies in both the United States and Europe.  On the Philadelphia
Stock Exchange,  for example,  contracts for half the size of the  corresponding
futures  contracts on the Chicago Board  Options  Exchange are traded with up to
nine months maturity in Marks, Sterling, Yen, Swiss Francs and Canadian dollars.
Options  can be  exercised  at any time during the  contract  life and require a
deposit subject to normal margin requirements.  Since a futures contract must be
exercised,  the Portfolio  must  continually  make up the margin  balance.  As a
result,  a wrong price move could result in the  Portfolio  losing more than the
original  investment as it cannot walk away from the futures  contract as it can
an option contract.

         The Portfolio  will purchase call and put options and sell such options
to terminate an existing  position.  Options on foreign  currency are similar to
options on stocks  except that an option on an interest  rate and/or index based
futures  contract gives the purchaser the right, in return for the premium paid,
to purchase or sell foreign currency,  rather than to purchase or sell stock, at
a specified exercise price at any time during the period of the option.

         The  Fund  intends  to use  foreign  currency  option  transactions  in
connection with hedging strategies.

Purchase of Put Options on Foreign Currencies

         The  purchase  of  protective  put  options  on a foreign  currency  is
analagous to the purchase of  protective  puts on  individual  stocks,  where an
absolute  level of protection is sought below which no additional  economic loss
would be incurred by the Portfolio.


<PAGE>


                                                                            A-22

Put options may be purchased  to hedge a portfolio of foreign  stocks or foreign
debt instruments or a position in the foreign currency upon which the put option
is based.

Purchase of Call Options on Foreign Currencies

         The purchase of a call option on foreign currency represents a means of
obtaining  temporary  exposure to market  appreciation  at limited  risk.  It is
analogous to the purchase of a call option on an  individual  stock which can be
used as a  substitute  for a  position  in the stock  itself.  Depending  on the
pricing of the option  compared to either the foreign  currency upon which it is
based, or upon the price of the foreign stock or foreign debt  instruments,  the
purchase  of a call option may be less risky than the  ownership  of the foreign
currency or the foreign  securities.  The Portfolio would purchase a call option
on a foreign  currency to hedge against an increase in the foreign currency or a
foreign market advance when the Portfolio is not fully invested.

         The Portfolio may employ new investment  techniques  involving  forward
foreign currency  exchange  contracts,  foreign  currency futures  contracts and
options on foreign  currencies in order to take  advantage of new  techniques in
these areas which may be  developed  from time to time and which are  consistent
with the  Portfolio's  investment  objective.  The  Portfolio  believes  that no
additional  techniques  have been  identified for employment by the Portfolio in
the foreseeable future other than those described above.

Currency Trading Risks

         Currency exchange trading may involve significant risks. The four major
types of risk the Portfolio  faces are exchange  rate risk,  interest rate risk,
credit risk and country risk.

Exchange Rate Risk

         Exchange  rate risk  results  from the  movement up and down of foreign
currency  values in  response  to shifting  market  supply and demand.  When the
Portfolio buys or sells a foreign currency,  an exposure called an open position
is created.  Until the time that  position can be "covered" by selling or buying
an equivalent amount of the same currency,  the Portfolio is exposed to the risk
that the exchange  rate might move against it. Since  exchange  rate changes can
readily move in one direction,  a position carried overnight or over a number of
days involves  greater risk than one carried a few minutes or hours.  Techniques
such as foreign  currency  forward and futures  contracts and options on foreign
currency are intended to be used by the Portfolio to reduce exchange rate risk.




<PAGE>


                                                                            A-23

Maturity Gaps and Interest Rate Risk

         Interest rate risk arises  whenever there are mismatches or gaps in the
maturity structure of the Portfolio's foreign exchange currency holdings,  which
is the total of its outstanding spot and forward or futures contracts.

         Foreign currency  transactions  often involve  borrowing short term and
lending longer term to benefit from the normal  tendency of interest rates to be
higher for longer  maturities.  However in foreign exchange  trading,  while the
maturity  pattern of interest  rates for one  currency is  important,  it is the
differential between interest rates for two currencies that is decisive.

Credit Risk

         Whenever the  Portfolio  enters into a foreign  exchange  contract,  it
faces a risk,  however small,  that the counterparty  will not perform under the
contract.  As a result there is a credit risk, although no extension of "credit"
is  intended.  To limit  credit  risk,  the  Portfolio  intends to evaluate  the
creditworthiness of each other party.

         Credit risk exists because the Portfolio's  counterparty  may be unable
or unwilling to fulfill its contractual obligations as a result of bankruptcy or
insolvency or when foreign exchange controls  prohibit  payment.  In any foreign
exchange transaction,  each party agrees to deliver a certain amount of currency
to the other on a particular date. In establishing its hedges a portfolio relies
on each contract being  completed.  If the contract is not  performed,  then the
Portfolio's hedge is eliminated,  and the Portfolio is exposed to any changes in
exchange  rates since the  contract  was  originated.  To put itself in the same
position it would have been in had the contract  been  performed,  the Portfolio
must arrange a new  transaction.  However,  the new  transaction  may have to be
arranged at an adverse  exchange  rate.  The trustee for a bankrupt  company may
elect to perform  those  contracts  that are  advantageous  to the  company  but
disclaim those  contracts that are  disadvantageous,  resulting in losses to the
Portfolio.

         Another  form of  credit  risk  stems  from the time  zone  differences
between  the U.S.  and  foreign  nations.  If the  Portfolio  sells  sterling it
generally must pay pounds to a  counterparty  earlier in the day than it will be
credited with dollars in New York. In the  intervening  hours,  the buyer can go
into  bankruptcy or can be declared  insolvent.  Thus,  the dollars may never be
credited to the Portfolio.

Country Risk

         At one time or another,  virtually  every country has  interfered  with
international transactions in its currency. Interference has

<PAGE>


                                                                            A-24

taken the form of  regulation  of the local  exchange  market,  restrictions  on
foreign  investment by residents or limits on inflows of  investment  funds from
abroad.  Governments  take such measures for example to improve control over the
domestic  banking  system or to  influence  the pattern of receipts and payments
between residents and foreigners.  In those cases,  restrictions on the exchange
market or on  international  transactions  are  intended  to affect the level or
movement of the exchange rate.  Occasionally a serious foreign exchange shortage
may  lead  to  payment  interruptions  or  debt  servicing  delays,  as  well as
interference in the exchange  market.  It has become  increasingly  difficult to
distinguish foreign exchange or credit risk from country risk.

         Changes in  regulations  or  restrictions  usually do have an important
exchange  market impact.  Most  disruptive are changes in rules which  interfere
with the normal  payments  mechanism.  If  government  regulations  change and a
counterparty  is either  forbidden  to perform or is  required  to do  something
extra,  then the Portfolio  might be left with an unintended open position or an
unintended  maturity  mismatch.  Dealing  with  such  unintended  long or  short
positions could result in unanticipated costs to the Portfolio.

         Other   changes  in  official   regulations   influence   international
investment  transactions.  If one of the factors affecting the buying or selling
of a currency changes,  the exchange rate is likely to respond.  Changes in such
controls  often are  unpredictable  and can create a  significant  exchange rate
response.

         Many major countries have moved toward  liberalization  of exchange and
payments   restrictions   in  recent  years  or  accepted  the  principle   that
restrictions  should be relaxed.  A few  industrial  countries have moved in the
other direction.  Important liberalizations were carried out by Switzerland, the
United Kingdom and Japan.  They  dismantled  mechanisms for  restricting  either
foreign exchange inflows  (Switzerland),  outflows (Britain) or elements of both
(Japan). By contrast, France and Mexico have recently tightened foreign exchange
controls.

         Overall,  many exchange markets are still heavily  restricted.  Several
countries limit access to the forward market to companies  financing  documented
export or import  transactions  in an effort to insulate  the market from purely
speculative  activities.  Some of these countries  permit local traders to enter
into forward contracts with residents but prohibit certain forward  transactions
with  nonresidents.  By  comparison,  other  countries  have strict  controls on
exchange  transactions  by  residents,  but permit  free  exchange  transactions
between local traders and non-residents. A few countries have established tiered
markets,  funneling  commercial  transactions  through one market and  financial
transactions through another. Outside the major industrial countries, relatively
free

                                                                            A-25

         foreign  exchange  markets are rare and  controls  on foreign  currency
transactions are extensive.

         Another aspect of country risk has to do with the possibility  that the
Portfolio  may be dealing  with a foreign  trader whose home country is facing a
payments  problem.  Even  though the  foreign  trader  intends to perform on its
foreign exchange contracts, the contracts are tied to other external liabilities
the country has incurred. As a result performance may be delayed, and can result
in unanticipated  cost to the Portfolio.  This aspect of country risk is a major
element in the  Portfolio's  credit judgment as to with whom it will deal and in
what amounts.

         Closing Purchase Transaction. A transaction in which an investor who is
obligated  as a writer of an option or seller of a futures  contract  terminates
his  obligation by purchasing on an Exchange an option of the same series as the

Keystone America World Bond Fund

NOTES TO FINANCIAL STATEMENTS

(1.) Significant Accounting Policies

Keystone America World Bond Fund (the "Fund") (formerly  Keystone America Global
Income Fund) is a  Massachusetts  business  trust for which  Keystone  Custodian
Funds, Inc.  ("Keystone") is the investment adviser. The Fund became part of the
Keystone  America  family of funds on April 19,  1989 and  Keystone  became  the
Fund's adviser on that date. It is registered  under the Investment  Company Act
of 1940 as a non-diversified, open-end investment company.

Effective  October 31, 1994, the Fund elected to change its fiscal year end from
December 31 to October 31.

The Fund  currently  offers Class A, Class B and Class C shares.  Class A shares
are offered at a public  offering price which includes a maximum sales charge of
4.75%  payable at the time of  purchase.  Class B shares  are sold  subject to a
contingent  deferred  sales  charge  payable  upon  redemption  which  decreases
depending on how long the shares have been held. Class C shares are sold subject
to a contingent deferred sales charge payable upon redemption within one year of
purchase.  Class C shares are  available  only through  dealers who have entered
into special distribution  agreements with Keystone Distributors,  Inc. ("KDI"),
the Fund's principal underwriter.

Keystone  is a  wholly-owned  subsidiary  of Keystone  Group,  Inc.  ("KGI"),  a
Delaware corporation.  KGI is privately owned by an investor group consisting of
members of current and former management of Keystone. Keystone Investor Resource
Center,  Inc., ("KIRC"),  a wholly-owned  subsidiary of Keystone,  is the Fund's
transfer agent.

The  following  is a summary of  significant  accounting  policies  consistently
followed  by the  Fund  in the  preparation  of its  financial  statements.  The
policies are in conformity with generally accepted accounting principles.

A.  Investments are usually valued at the closing sales price, or in the absence
of  sales  and for  over-the-  counter  securities,  the  mean of bid and  asked
quotations.  Management  values the  following  securities at prices it deems in
good faith, by or under the direction of the Board of Trustees,  to be fair: (a)
securities (including  restricted  securities) for which complete quotations are
not  readily  available  and  (b)  listed  securities  if,  in  the  opinion  of
management, the last sales price does not reflect a current value, or if no sale
occurred.  Foreign currency amounts are translated into United States dollars as
follows:  market value of investments,  assets and liabilities at the daily rate
of exchange; purchases and sales of investments, income and expenses at the rate
of exchange prevailing on the dates of such transactions. Net unrealized foreign
exchange gains/losses are a component of unrealized appreciation/depreciation of
investments.

Short-term investments,  if purchased with maturities of sixty days or less, are
valued at amortized cost (original  purchase price as adjusted for  amortization
of premium or accretion of discount  which when combined  with accrued  interest
approximates  market).  Short-term  investments maturing in more than sixty days
for which market  quotations are readily  available are valued at current market
value.  Short-term  investments maturing in more than sixty days, which are held
on the  sixtieth day prior to  maturity,  are valued at  amortized  cost (market
value on the sixtieth day adjusted for  amortization  of premium or accretion of
discount which when combined with accrued  interest  approximates  market).  All
other securities and other assets are valued at fair value as determined in good
faith using methods prescribed by the Board of Trustees.

Investments  denominated  in foreign  currencies  are adjusted  daily to reflect
changes in exchange  rates.  Market  quotations are not considered to be readily
available for long-term  corporate bonds and notes;  such investments are stated
at fair  value on the  basis  of  valuations  furnished  by a  pricing  service,
approved by the Board of Trustees, which determines valuations

<PAGE>
                                                                             F-9
for normal,  institutional-size  trading units of such securities  using methods
based on market transactions for comparable securities and various relationships
between securities which are generally recognized by institutional traders.

B. Securities  transactions are accounted for on the trade date.  Realized gains
and  losses are  computed  on the  identified  cost  basis.  Gains and losses on
foreign currency related transactions are treated as ordinary income for federal
income tax  purposes.  Interest  income is  recorded  on the  accrual  basis and
dividend  income is  recorded  on the  ex-dividend  date.  Distributions  to the
shareholders  are  recorded  by the Fund at the close of  business on the record
date.

C. The Fund has qualified,  and intends to qualify in the future, as a regulated
investment  company  under  the  Internal  Revenue  Code  of  1986,  as  amended
("Internal Revenue Code").  Thus, the Fund expects to be relieved of any federal
income or excise tax liability by distributing all of its net taxable investment
income and net taxable  capital  gains,  if any, to its  shareholders.  The Fund
intends to avoid excise tax liability by making the required distributions under
the Internal Revenue Code.

D. When the Fund enters into a repurchase  agreement  (a purchase of  securities
whereby the seller agrees to repurchase the securities at a mutually agreed upon
date and price), the repurchase price of the securities will generally equal the
amount paid by the Fund plus a negotiated  interest amount. The seller under the
repurchase  agreement will be required to provide  securities  ("collateral") to
the  Fund  whose  value  will be  maintained  at an  amount  not  less  than the
repurchase  price,  and  which  generally  will  be  maintained  at  101% of the
repurchase  price.  The Fund  monitors the value of collateral on a daily basis,
and if the value of the collateral falls below required levels, the Fund intends
to seek  additional  collateral  from the  seller or  terminate  the  repurchase
agreement.  If the seller  defaults,  the Fund would suffer a loss to the extent
that the proceeds from the sale of the underlying  securities were less than the
repurchase  price.  Any such loss would be  increased  by any cost  incurred  on
disposing of such securities.  If bankruptcy  proceedings are commenced  against
the seller under the repurchase agreement, the realization on the collateral may
be delayed or limited.  Repurchase  agreements  entered into by the Fund will be
limited to  transactions  with  dealers or  domestic  banks  believed to present
minimal  credit  risks,  and the Fund  will  take  constructive  receipt  of all
securities underlying repurchase agreements until such agreements expire.

E. From time to time the Fund may enter into forward foreign  currency  exchange
contracts to hedge certain foreign  currency  assets.  Contracts are recorded at
market  value.  Realized  gains and losses  arising from such  transactions  are
included in net realized gain (loss) on foreign currency  related  transactions.
The Fund is subject to the credit  risk that the other  party will not  complete
the obligations of the contract.

F. The Fund  distributes net investment  income quarterly and net capital gains,
if any,  annually.  Commencing  with the November  1994  distribution,  the Fund
intends to distribute  net investment  income  monthly.  Distributions  from net
investment income are based on tax basis net income. From time to time, the Fund
may   distribute   dividends   which  exceed  book  basis  net  income.   Excess
distributions were previously charged to the Fund's undistributed net investment
income.  Distributions  after January 31, 1990 were charged to undistributed net
investment  income  to the  extent  of book  basis  net  income  available.  The
remainder of the distributions was charged to paid-in capital. Effective January
1, 1993, the Fund adopted Statement of Position 93-2: Determination, Disclosure,
and  Financial  Statement  Presentation  of Income,  Capital  Gain and Return of
Capital  Distributions by Investment  Companies.  As a result of this statement,
the Fund changed the classification

<PAGE>
                                                                            F-10
of  distributions  to shareholders  to better  disclose the differences  between
financial  statement  amounts and  distributions  determined in accordance  with
income tax regulations.  Accordingly,  amounts as of December 31, 1993 have been
restated to reflect an increase  in paid-in  capital of $29,095,  an increase in
undistributed  investment  income--net of $71,206, and a decrease in accumulated
net  realized  gains  (losses)  on  investment  and  foreign   currency  related
transactions  of  $100,301.   The  significant   differences  between  financial
statement  amounts   available  for  distribution  and  distributions   made  in
accordance  with income tax  regulations  are due to the  deferral of losses for
income tax purposes that have been recognized for financial  statement  purposes
and treatment of foreign currency gains as ordinary income for tax purposes.

(2.) Capital Share Transactions

The Trust Agreement  authorizes the issuance of an unlimited number of shares of

The Fund bears some of the costs of selling its shares under a Distribution Plan
adopted with respect to its Class A, Class B and Class C shares pursuant to Rule
12b-1 under the Investment Company Act of 1940 ("1940 Act").

The Class A Distribution  Plan provides for payments which are currently limited
to 0.25%  annually of the average daily net asset value of Class A shares to pay
expenses of the distribution of Class A shares.  Amounts paid by the Fund to KDI
under the Class A distribution  Plan are currently  used to pay others,  such as
dealers,  service fees at an annual rate of up to 0.25% of the average net asset
value of shares sold by such others and  remaining  outstanding  on the books of
the Fund for specified periods.

The Class B  Distribution  Plan provides for payments at an annual rate of up to
1.00% of the average  daily net asset value of Class B shares to pay expenses of
the  distribution of Class B shares.  Amounts paid by the Fund under the Class B
Distribution Plan are currently used to pay others (dealers) (i) a commission at
the time of  purchase  normally  equal to 3.00% of the value of each share sold;
and/or  (ii)  service  fees at an annual  rate of 0.25% of the average net asset
value of shares sold by such others and  remaining  outstanding  on the books of
the Fund for specified periods.

The Class C  Distribution  Plan provides for payments at an annual rate of up to
1.00% of the average daily net asset value of Class C shares to pay expenses for
the  distribution of Class C shares.  Amounts paid by the Fund under the Class C
Distribution  Plan are currently  used to pay others  (dealers) (i) a payment at
the time of purchase of 1.00% of the value of each share sold,  such  payment to
consist of a commission in the amount of 0.75% and the first year's  service fee
in advance in the amount of 0.25%;  and (ii) beginning  approximately  15 months
after  purchase,  a commission at an annual rate of 0.75% (subject to applicable
limitations  imposed  by the rules of the  National  Association  of  Securities
Dealers, Inc.) and service fees at an annual rate of 0.25%, respectively, of the
average  net  asset  value  of each  share  sold by such  others  and  remaining
outstanding on the books of the Fund for specified periods.

Each of the  Distribution  Plans may be  terminated at any time by a vote of the
Independent Trustees or by a vote of a majority of the outstanding voting shares
of  the  respective  class.  However,  after  the  termination  of the  Class  B
Distribution Plan, KDI would be entitled to receive payment,  at the annual rate
of 1.00% of the average daily net asset value of Class B shares, as compensation
for its  services  which had been  earned at any time  during  which the Class B
Distribution Plan was in effect.  Unreimbursed  distribution expenses at October
31, 1994 were $92,803 and $7,931 for Class B and Class C shares, respectively.

For the  period  from  January 1, 1994 to October  31,  1994,  the Fund paid KDI
$13,778, $26,882 and $14,984 under its Class A, Class B and Class C Distribution
Plans, respectively.

Presently,  the Fund's class-specific  expenses are limited to Distribution Plan
expenses incurred by a class of shares.

(4.) Investment Management and Transactions with Affiliates

Under the terms of an  Investment  Advisory  and  Management  Agreement  between
Keystone   and  the  Fund,   Keystone   provides   investment   management   and
administrative  services  to the  Fund.  In  return,  Keystone  receives  a fee,
computed and charged to the net assets of the Fund daily,  calculated  at a rate
of 1.5% of  gross  investment  income  plus an  amount  determined  by  applying
percentage rates, which start at 0.50% and decline,  as net assets increase,  to
0.40% per annum,  to the net asset value of the Fund. The Fund paid a management
fee of $61,697 to Keystone  for the period  from  January 1, 1994 to October 31,
1994 which  represented  0.50% of the Fund's average net assets on an annualized
basis.

During the period from  January 31, 1994 to October 31,  1994,  the Fund paid or
accrued  to KIRC  $13,654  as  reimbursement  for  certain  accounting,  tax and
printing services and $32,493 for transfer agent fees.

Keystone has voluntarily limited ordinary expenses of Class A shares of the Fund
to 2.20%  annually  of  average  daily net assets  and has  voluntarily  limited
ordinary  expenses  of Class B and Class C shares to 2.95%  annually  of average
daily net assets.  Keystone  would not be required to reimburse  the Fund to the
extent such  reimbursement  would result in the Fund's inability to qualify as a
regulated  investment company under the provisions of the Internal Revenue Code.
In accordance with these voluntary expense limitations,  Keystone reimbursed the
Fund during the period from January 1, 1994 to October 31, 1994  $2,943,  $2,200
and $1,119 for Class A, Class B and Class C shares, respectively.  Keystone does
not intend to seek repayment of these amounts.

Certain  officers and/or Directors of Keystone are also officers and/or Trustees
of  the  Fund.   Officers  of  Keystone  and  affiliated   Trustees  receive  no
compensation directly from the Fund. Currently,  the Independent Trustees of the
Fund receive no compensation for their services.

(5.) Distributions to Shareholders

A distribution of net investment income of $0.05, $0.045 and $0.045 for Class A,
Class B and Class C shares, respectively,  was declared payable December 6, 1994
to shareholders of record November 21, 1994. This  distribution is not reflected
in  the  accompanying   financial  statements.   The  Fund  distributes  to  its
shareholders dividends from net investment income quarterly and all net realized
long-term  capital gains,  if any,  annually.  Commencing with the November 1994
distribution,  the Fund intends to distribute net investment income monthly. Any
taxable  distribution  which is declared in December  and paid in the  following
fiscal year will be taxable to shareholders in the year declared.

(6.) Forward Foreign Currency Exchange Contracts

At October 31, 1994,  the Fund had entered into the  following  forward  foreign
currency  exchange  contracts  that  obligate the Fund to deliver  currencies at
specified  future dates.  The net  unrealized  depreciation  of $72,027 on these

INDEPENDENT AUDITORS' REPORT  The Trustees and Shareholders
Keystone America World Bond Fund

We have audited the accompanying statement of assets and liabilities of Keystone
America World Bond Fund,  including the schedule of  investments,  as of October
31, 1994, and the related statement of operations for the period from January 1,
1994 to October 31, 1994, the statements of changes in net assets for the period
from  January 1, 1994 to October 31, 1994 and the year ended  December  31, 1993
and the financial  highlights for the period from January 1, 1994 to October 31,
1994 and each of the years in the five-year  period ended  December 31, 1993 for
Class A shares and the  periods  from  January 1, 1994 to October  31,  1994 and
August 2, 1993 (date of initial public  offering) to December 31, 1993 for Class
B and Class C shares.  These financial  statements and financial  highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.  The financial  highlights  for the year ended December 31, 1988 and for
the period  January 9, 1987  (commencement  of  operations) to December 31, 1987
were audited by other auditors whose report,  dated February 3, 1989,  expressed
an unqualified opinion thereon.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
October 31, 1994, by  correspondence  with the  custodian and brokers.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above  present  fairly,  in all material  respects,  the  financial  position of
Keystone  America  World Bond Fund as of October  31,  1994,  the results of its
operations  for the period from January 1, 1994 to October 31, 1994, the changes
in its net assets for the period  from  January 1, 1994 to October  31, 1994 and
the year ended December 31, 1993,  and the financial  highlights for each of the
periods  subsequent to December 31, 1988 stated in the first  paragraph above in
conformity with generally accepted accounting principles.
