                                  INTRODUCTION

    The Alger Fund's  portfolios,  other than the Alger Money Market  Portfolio,
offer a choice of two classes of shares having different sales charges,  ongoing
fees and other  features.  You can choose the method of  purchasing  shares of a
portfolio  that is most  beneficial in terms of the amount of the purchase,  the
length of time you expect to hold shares and other circumstances.

Class A Shares

    An investor  purchasing Class A shares may pay a sales charge at the time of
purchase.  Class A shares  are not  subject to a charge  when they are  redeemed
(except for shares  purchased  for total  proceeds of $1 million or more,  which
have no initial  sales charge and which may be subject to a contingent  deferred
sales charge  ["CDSC"]).  The initial  sales charge may be reduced or waived for
certain  purchases.  Class A shares are subject to a  shareholder  servicing fee
equal to an annual  rate of .25% of the  Portfolio's  average  daily net  assets
attributable to its Class A shares.  See "How to Purchase  Shares--Class A Share
Information".

Class B Shares

   
    Class B shares have no initial sales charge, but may be subject to a CDSC of
up to 5% if you redeem within six years of purchase. They are subject to a 12b-1
fee of .75% of the Portfolio's  average daily net assets attributable to Class B
shares.  Class B shares also pay a shareholder  servicing  fee  calculated at an
annual rate of .25% of the Portfolio's  average daily net assets attributable to
its Class B shares.  Class B shares  provide an investor  the benefit of putting
all of the  investor's  dollars to work from the time the investment is made but
will have a higher  expense ratio and generally  will pay lower  dividends  than
Class A shares due to the Rule 12b-1 fee on Class B shares. See "How to Purchase
Shares--Class B Share Information".

Portfolio Expenses

    The Table below is designed  to assist you in  understanding  the direct and
indirect costs and expenses that you will bear as a shareholder.  The Example on
the next page shows the amount of expenses you would pay on a $1,000  investment
in each class of shares of the Portfolios. These amounts assume the reinvestment
of all  dividends and  distributions,  payment of any  applicable  initial sales
charge or  contingent  deferred  sales charge and payment by the  Portfolios  of
operating  expenses as shown in the Table under Annual Fund Operating  Expenses.
The Example is an  illustration  only and actual expenses may be greater or less
than those shown.

(a)  The sales charge  applicable to Class A shares set forth in the above table
     is the maximum charge imposed upon the purchase of shares. Shareholders may
     pay less than 4.75%  depending on the amount  invested in Class A shares of
     the Fund. See "How to Purchase Shares--Class A Share Information."
(b)  Class A purchases of $1 million or more are not subject to an initial sales
     charge;  however a contingent deferred sales charge of 1% may be imposed on
     certain  redemptions within one year following such purchases.  See "How to
     Purchase  Shares--Class A Share  Information."  For Class B purchases,  the
     amount of the contingent deferred sales charge, if applicable,  will depend
     on the number of years since the shareholder made the purchase payment. See
     "How to Purchase Shares--Contingent Deferred Sales Charge."
(c)  The Fund reimburses Fred Alger & Company,  Incorporated for the expenses it
     incurs in  distributing  Class B shares of each  Portfolio  other  than the
     Alger Money  Market  Portfolio  at the  maximum  annual rate of .75% of the
     Class' average daily net assets.  Such  reimbursement  includes interest on
     the unreimbursed  carryforward.  Long-term  shareholders  paying 12b-1 fees
     pursuant to the Fund's plan of distribution  may pay more than the economic
     equivalent of the maximum front-end sales charges permitted by the rules of
     the National Association of Securities Dealers, Inc.
(d)  Included in Other Expenses of the Alger Capital  Appreciation  Portfolio is
     0.02% of interest expense.
(e)  Other  Expenses for the Alger Money Market  Portfolio have been restated to
     reflect current fees.
(f)  Other Expenses for a Portfolio's  Class A shares are estimated on the basis
     of  amounts  incurred  by the  Portfolio's  Class B shares  during its most
     recent fiscal year.

                             HOW TO PURCHASE SHARES

IN GENERAL

   
    The Fund  offers  Class A and Class B shares  (except  for the  Alger  Money
Market Portfolio which has a single class of shares) for investors. The offering
price for Class A shares is net asset  value plus an initial  sales  charge that
declines for larger purchases (see "Class A Share Information" below). Purchases
of Class A shares in  cumulative  amounts  of $1 million or more have no initial
sales charge but may be subject to a contingent  deferred sales charge  ("CDSC")
if held for less than one  year.  The  offering  price for Class B shares is net
asset  value with no initial  sales  charge but such  shares may be subject to a
CDSC if held for less than six years (see  "Contingent  Deferred  Sales  Charge"
below).  The  Alger  Money  Market  Portfolio  is sold  without  an  initial  or
contingent  deferred  sales  charge.  The minimum  initial  investment  for each
Portfolio  is $500,  and  subsequent  investments  must be at least  $25.  These
minimums may be waived  under  certain  circumstances.  The Fund or the transfer
agent may reject any purchase order.
    

METHODS OF PURCHASING SHARES

  MAIL

    You can buy shares  through Alger  Shareholder  Services,  Inc.,  the Fund's
transfer agent ("Transfer  Agent"),  by filling out the New Account  Application
and  returning  it with a  check  drawn  on a U.S.  bank  to  Alger  Shareholder
Services, Inc. at 30 Montgomery Street, Box 2001, Jersey City, NJ 07302.

  WIRE TRANSFERS

    Investors  establishing  new accounts by wire transfer  should forward their
completed  New Account  Applications  to the  Transfer  Agent,  stating that the
account  was  established  by wire  transfer  and the  date  and  amount  of the
transfer.  Further information  regarding wire transfers is available by calling
(800) 992-3863.

  BROKERS

   
    You can buy shares of the Portfolios  through  brokers who have signed sales
agreements with Fred Alger & Company, Incorporated ("Alger Inc.").
    

  PROCESSING ORGANIZATIONS

    You  can  buy  shares  through  a  "Processing  Organization",  which  is  a
broker-dealer, bank or other financial institution that purchases shares for its
customers.  Processing  Organizations  may impose  charges and  restrictions  in
addition  to or  different  from those  applicable  if you invest  with the Fund
directly.  Therefore,  you should read the materials  provided by the Processing
Organization   in  conjunction   with  this   Prospectus.   Certain   Processing
Organizations may receive  compensation from the Fund, Alger Inc., or any of its
affiliates.

CLASS A SHARE INFORMATION

    Class A shares are  available  in all  Portfolios  except  the Money  Market
Portfolio.  These shares may be subject to an initial  sales  charge  (indicated
below) on purchases of less than $1 million.  Purchases of Class A shares in the
amount of $1 million or more avoid the initial sales charge,  but are subject to
a CDSC of 1% if they  are  redeemed  within  12  months  of  purchase.  With the
exception of differing  applicable  holding  periods,  the same  procedures  and
conditions will apply to the CDSC for $1 million  purchases of Class A shares as
apply to the CDSC for Class B shares. See "Class B Share Information--Contingent
Deferred Sales Charge" below.

  INITIAL SALES CHARGE

    The  sales  charges  applicable  to the  purchase  of Class A shares  of the
Portfolios (other than the Alger Money Market Portfolio) are:

                        Sales Charge     Sales Charge   Dealer Allowance
       Purchase            as % of          as % of          as % of
        Amount         Offering Price   Net Asset Value  Offering Price
- ----------------------- -------------  ---------------- ----------------
Less than $100,000           4.75%            4.99%            4.00%
$100,000 - $249,999          4.00%            4.17%            3.25%
$250,000 - $499,999          3.00%            3.09%            2.50%
$500,000 - $999,999          2.25%            2.30%            1.75%
$1,000,000 and over             *                *             1.00%
- ------------------
* Purchases of Class A shares,  which when  combined  with  current  holdings of
  Class A shares  offered with a sales charge equal or exceed  $1,000,000 in the
  aggregate,  may be made at net asset value  without any initial  sales charge,
  but will be subject to a CDSC of 1.00% on redemptions made within 12 months of
  purchase.  The CDSC is  waived  in the same  circumstances  in which  the CDSC
  applicable to Class B shares is waived. See "Waiver of Sales Charges".

                                       1
<PAGE>

    The reduced sales charges shown above apply to the aggregate of purchases of
Class A shares  of the Fund  made at one time  (unless  a Letter of Intent is on
file with the Fund) by "any person," which  includes an  individual,  his or her
spouse and children,  or a trustee or other fiduciary of a single trust,  estate
or single fiduciary account. See "Letter of Intent".

    From  time  to  time  Alger  Inc.   may  reallow  to  brokers  or  financial
intermediaries  all or  substantially  all of the initial sales  charge.  To the
extent that it does so, such  persons  may be deemed to be  underwriters  of the
Fund as defined in the Securities Act of 1933, as amended.

  RIGHT OF ACCUMULATION

    Class A shares of the Fund may be  purchased  by "any  person"  (as  defined
above) at a reduced sales charge as determined by aggregating  the dollar amount
of the new  purchase and the current  value (at  offering  price) of all Class A
shares  of the Fund then  held by such  person  and  applying  the sales  charge
applicable to such  aggregate.  In order to obtain such discount,  the purchaser
must  provide  sufficient   information  at  the  time  of  purchase  to  permit
verification that the purchase qualifies for the reduced sales charge. The right
of accumulation is subject to  modification or  discontinuance  at any time with
respect to all shares purchased thereafter.

  LETTER OF INTENT

    A Letter of Intent ("LOI") contemplating  aggregate purchases of $100,000 or
more provides an opportunity for an investor to obtain a reduced sales charge by
aggregating  investments  over a 13-month  period,  provided  that the  investor
refers to such LOI when placing  orders.  For  purposes of a LOI, the  "Purchase
Amount" as referred to in the preceding sales charge table includes purchases of
all Class A shares of the Fund offered with a sales charge over the following 13
months.

    An  alternative  is to compute the  13-month  period  starting up to 90 days
before the date of execution of the LOI. The minimum  initial  investment  under
the LOI is 5% of the total LOI amount.  Each  investment  made during the period
receives  the  reduced  sales  charge  applicable  to the  total  amount  of the
investment goal. Shares purchased with the first 5% of the total LOI amount will
be held in escrow by the  Transfer  Agent to assure any  necessary  payment of a
higher applicable sales charge if the investment goal is not met. If the goal is
not achieved within the period, the investor must pay the difference between the
sales charges  applicable to the purchases made and the charges previously paid,
or an appropriate number of escrowed shares will be redeemed.

CLASS B SHARE INFORMATION

    Class B shares are sold at net asset  value with no  initial  sales  charge.
This  provides  investors the benefit of putting all of their dollars to work at
the time the investment is made.  However,  a CDSC of up to 5% may be imposed if
you redeem your shares within six years of purchase.  Class B shares are subject
to certain Rule 12b-1 fees as well, which are described below.

  CONTINGENT DEFERRED SALES CHARGE

    With  respect  to  Class B  shares,  there is no  initial  sales  charge  on
purchases  of shares of any  Portfolio,  but a CDSC may be  charged  on  certain
redemptions. The CDSC is imposed on any redemption that causes the current value
of your  account  in the Class B shares of any  Portfolio  other  than the Alger
Money Market Portfolio to fall below the amount of purchase payments made during
a six-year  holding  period.  There is no CDSC on redemptions of (i) shares that
represent  appreciation on your original  investment,  or (ii) shares  purchased
through  reinvestment  of dividends and capital gains. No CDSC is imposed on the
redemption of shares of the Alger Money Market Portfolio,  except for redemption
of  shares  acquired  in  exchange  for  Class B  shares  (and  certain  Class A
shares--see  "How to Purchase  Shares--Class A Share  Information") of the other
Portfolios.  The amount of the charge is based on the length of time  shares are
held, according to the following table:


                                       2

                                                       Contingent  
                                                     Deferred Sales
              Years Shares Were Held                     Charge
        ----------------------------------             ----------
Less than one.....................................         5%
One but less than two.............................         4%
Two but less than three...........................         3%
Three but less than four..........................         2%
Four but less than five...........................         2%
Five but less than six............................         1%
Six and greater...................................         0%

    For  purposes  of the  CDSC,  it is  assumed  that the Class B shares of the
Portfolio  from  which  the  redemption  is made are the  Class B shares of that
Portfolio held the longest and which result in the lowest charge.

    Redemptions  of shares of each of the Portfolios are deemed to be made first
from  amounts,  if any, to which the charge  does not apply.  Since no charge is
imposed on shares  purchased  and retained in the Alger Money Market  Portfolio,
you may wish to consider  redeeming those shares, if any, before redeeming Class
B shares  of the  other  Portfolios.  Please  see the  Statement  of  Additional
Information  for  examples  of how  the  CDSC  is  calculated  when  shares  are
exchanged.

  DISTRIBUTION PLAN

    With respect to Class B shares, the Fund has adopted an Amended and Restated
Distribution  Plan (the  "Plan")  under which  Class B shares of each  Portfolio
other than the Alger Money Market  Portfolio  may  reimburse  Alger Inc. for the
expenses it incurs in promoting sales of that  Portfolio's  Class B shares--at a
maximum annual rate of .75% of its average daily net assets  represented by such
shares (Rule 12b-1 fees).  This fee is  sometimes  described as an  "asset-based
sales charge" and allows investors to buy shares without an initial sales charge
while allowing Alger Inc. to compensate  dealers that sell Class B shares of the
Portfolios.  Alger  Inc.  pays  sales  commissions  of up to 4.75% of the amount
invested  to  dealers  from its own  resources  at the time of sale.  Alger Inc.
retains the asset-based  sales charge to recoup the sales  commissions and other
sales related  expenses its pays. Any CDSCs on Class B shares  received by Alger
Inc.  will  reduce  the  amount to be  reimbursed  under the  Plan.  Any  excess
distribution expenses may be carried forward,  with interest,  and reimbursed in
future years.

WAIVERS OF SALES CHARGES

    No Initial  Sales Charge  (Class A) or CDSC (Class A or B) is imposed on (1)
purchases or redemptions by (i) employees of Alger Inc. and its affiliates, (ii)
IRAs,  Keogh Plans and  employee  benefit  plans for those  employees  and (iii)
spouses,  children,  siblings and parents of those employees and trusts of which
those individuals are beneficiaries,  as long as orders for the shares on behalf
of those  individuals and trusts were placed by the employees;  (2) purchases or
redemptions by (i) accounts managed by investment  advisory  affiliates of Alger
Inc. that are registered under the Investment  Advisers Act of 1940, as amended,
(ii) employees,  participants and  beneficiaries of those accounts,  (iii) IRAs,
Keogh Plans and employee  benefit plans for those  employees,  participants  and
beneficiaries   and  (iv)  spouses  and  minor  children  of  those   employees,
participants  and  beneficiaries as long as orders for the shares were placed by
the employees,  participants and beneficiaries;  (3) purchases or redemptions by
directors or trustees of any  investment  company for which Alger Inc. or any of
its affiliates  serves as investment  adviser or  distributor;  (4) purchases or
redemptions  of shares held  through  defined  contribution  plans as defined by
ERISA;  (5) purchases or redemptions by an investment  company  registered under
the  Investment  Company Act of 1940 in connection  with the  combination of the
investment  company  with the Fund by  merger,  acquisition  of assets or by any
other  transaction;  (6)  purchases  or  redemptions  by  registered  investment
advisers,  banks,  trust companies and other financial  institutions  exercising
discretionary  authority with respect to the money invested in Fund shares;  (7)
purchases  or  redemptions  by  registered  investment  advisers  for  their own
accounts;  (8)  purchases  or  redemptions  by  a  Processing  Organization,  as
shareholder  of  record,  on  behalf of (i)  investment  advisers  or  financial
planners trading for their own accounts or the accounts of their clients and who


                                       3
<PAGE>

charge  a  management,  consulting  or  other  fee for  their  services  ("wrap"
accounts); and clients of such investment advisers or financial planners trading
for their own accounts if the accounts are linked to the master  account of such
investment  adviser  or  financial  planner  on the  books  and  records  of the
Processing Organization, and (ii) retirement and deferred compensation plans and
trusts used to fund those plans;  and (9) purchases or redemptions by registered
representatives  of  broker-dealers  which have  entered  into  Selected  Dealer
Agreements with Alger Inc., and their spouses, children, siblings and parents.

   
    The CDSC is also waived on (1)  Systematic  Withdrawal  Plan  payments,  (2)
redemptions  of shares  in  connection  with  certain  required  post-retirement
withdrawals  from an IRA or other  retirement plan or (3) redemptions  following
the death or disability of a shareholder.
    

    Investors  purchasing Class A shares subject to one of the foregoing waivers
are required to claim and substantiate  their  eligibility for the waiver at the
time of purchase. It is also the responsibility of shareholders redeeming shares
otherwise  subject to a CDSC but qualifying for a waiver of the charge to assert
this status at the time of redemption. Information regarding these procedures is
available by contacting the Fund at (1-800) 992-3863.

                               HOW TO SELL SHARES

   
    You can sell  (redeem)  some or all of your shares on any business day. Your
shares will be sold at the next net asset value calculated after your redemption
request is received and accepted by the Transfer  Agent and your payment will be
made by check within  seven days. A CDSC may be charged on certain  redemptions.
See "How to Purchase  Shares--Class  A Share  Information"  and "How to Purchase

payments  delayed under  certain  emergency  circumstances  as determined by the
Securities and Exchange  Commission.  The Fund's  Transfer Agent will reject any
redemption  request made within 15 days after  receipt of the purchase  check or
the TelePurchase order against which such redemption is requested.  You can sell
your shares in any of the following  ways:  by mail,  by telephone,  by check or
through your broker. Please note that, although the Fund is authorized to charge
a fee of $17.00 for each wire redemption, it does not currently intend to do so.
    

MAIL

    You should send a letter of  instruction to the Transfer Agent that includes
your name, account number,  Portfolio name, the Class of shares (if applicable),
the  number of shares or dollar  amount and where you want the money to be sent.
The letter must be signed by all  authorized  signers and, if the  redemption is
for more than $5,000 or if the proceeds are to be sent to an address  other than
the address of record,  the  signature  must be  guaranteed.  In  addition,  any
request  for  redemption  proceeds to be sent to the address of record must have
the signature(s) guaranteed if made within 60 days of changing your address. The
Transfer  Agent will accept a signature  guarantee  by the  following  financial
institutions:  a U.S. bank, trust company,  broker, dealer, municipal securities
broker or dealer,  government securities broker or dealer, credit union which is
authorized  to  provide  signature  guarantees,  national  securities  exchange,
registered securities association or clearing agency.

TELEPHONE

    If you wish to use this service,  you should mark the appropriate box on the
New Account  Application or send a written request with a guaranteed  signature.
To sell shares by telephone,  please call (1-800)  992-3863.  If your redemption
request is received  before  12:00 noon  Eastern time for the Alger Money Market
Portfolio,  your  redemption  proceeds  will be wired the same  day.  Redemption
requests for  Portfolios  other than the Alger Money Market  Portfolio  received
prior to the close of business  of the New York Stock  Exchange  (normally  4:00
p.m.  Eastern time) and requests  received  after 12:00 noon for the Alger Money
Market  Portfolio  will be paid on the next  business  day. If your proceeds are
less than $2,500, they will be mailed to your address of record. If the proceeds


                                       4
<PAGE>

are more than $2,500  they will be mailed to your  address of record or wired to
your designated bank account. Telephone requests for a check to be mailed to the
address of record is not  available  within 60 days of  changing  your  address.
Redemption  requests  made before  12:00 noon  Eastern  time for the Alger Money
Market Portfolio will not receive a dividend for that day.

    The Fund, the Transfer Agent and their  affiliates are not liable for acting
in good faith on telephone  instructions  relating to your  account,  so long as
they follow reasonable  procedures to determine that the telephone  instructions
are genuine.  Such  procedures  may include  recording the  telephone  calls and
requiring some form of personal  identification.  You should verify the accuracy
of  telephone  transactions   immediately  upon  receipt  of  your  confirmation
statement.

CHECK (ALGER MONEY MARKET PORTFOLIO ONLY)

    You may  redeem  shares in your  Alger  Money  Market  Portfolio  account by
writing a check for at least $500.  Dividends are earned until the check clears.
If you mark the  appropriate  box on the New  Account  Application  and sign the
signature card, the Fund will send you redemption checks. There is no charge for
the first five checks you write in any one  calendar  year.  You will be charged
$2.50 for each additional check you write.

    Your  redemption may be reduced by any applicable CDSC (see "How to Purchase
Shares--Class A Share  Information"  and "How to Purchase Shares --Class B Share
Information"). If your account is not adequate to cover the amount of your check
and any applicable CDSC, the check will be returned marked  insufficient  funds.
As a result, checks should not be used to close an account.

    The use of the check  redemption  procedure  does not give rise to a banking
relationship  between the  shareholder  and the  Transfer  Agent,  which will be
acting solely as transfer agent for the Portfolio.

REDEMPTION IN KIND

    Under  unusual  circumstances,  shares of a Portfolio  may be  redeemed  "in
kind",  which means that the  redemption  proceeds will be paid with  securities
which are held by the  Portfolio.  Please refer to the  Statement of  Additional
Information for more details.

                            SPECIAL INVESTOR SERVICES

EXCHANGE PRIVILEGE

    Except as limited  below,  shareholders  may  exchange  some or all of their
Portfolio  shares  for  shares  of  another  Portfolio  of  the  Fund.  Class  A
shareholders  may exchange their shares for Class A shares of another  Portfolio
or for shares of the Money Market  Portfolio.  Class B shareholders may exchange
their shares for Class B shares of another  Portfolio or for shares of the Money
Market Portfolio.  Money Market Portfolio shares acquired by direct purchase may
be exchanged for Class A or Class B shares of another  Portfolio;  however,  any
applicable sales charge will apply to the shares acquired,  depending upon their
Class.  Shares of the Money Market Portfolio acquired by exchange rather than by
direct purchase may be exchanged for shares of another  Portfolio,  but only for
shares of the same  Class as those  originally  exchanged  for the Money  Market
Portfolio  shares.  The  period  of time  shares  are held in the  Money  Market
Portfolio shall not be considered in the calculation of a CDSC.

    If you  want to  authorize  exchanges  by  telephone,  you  should  mark the
appropriate box on the New Account Application. For tax purposes, an exchange of
shares is treated  as a sale of the shares  exchanged  and,  therefore,  you may
realize a taxable gain or loss when you exchange shares.  Shares exchanged prior
to the close of  business  of the New York Stock  Exchange  (normally  4:00 p.m.
Eastern time) from the Alger Money Market  Portfolio to any other Portfolio will
receive  dividends  from the Alger  Money  Market  Portfolio  for the day of the
exchange.  Shares of the Alger Money Market  Portfolio  received in exchange for
shares of any other Portfolio will earn dividends beginning on the next business
day after the exchange.

    You may make up to six  exchanges  annually by telephone or in writing.  The
Fund may charge a $5.00 transaction fee for each exchange,  although it does not
intend to do so at present.  You will be notified at least 60 days in advance if
the Fund decides to impose this fee. The Fund reserves the right to terminate or
modify the exchange privilege upon notice to shareholders.

    The  TelePurchase  Privilege allows you to purchase Fund shares by telephone
(minimum $500,  maximum  $50,000) by filling out the appropriate  section of the
New Account  Application or sending an Additional  Services Form to the Transfer

    The  TeleRedemption  Privilege  allows you to transfer  funds (minimum $500,
maximum  $50,000)  between your Fund account and your  designated  bank account.
Redemption  proceeds will be transferred to your bank account,  generally within
two business days after your redemption  request is received.  Although the Fund
is  authorized  to  charge a fee of $17.00  for each  Automated  Clearing  House
redemption, it does not currently intend to do so.

    To use this privilege,  your bank must be a member of the Automated Clearing
House. Shares held in any Alger retirement plan and shares issued in certificate
form are not eligible for this service.

RETIREMENT  PLANS

    Shares of the Portfolios are available as an investment for your  retirement
plans,  including IRAs, Keogh Plans, corporate pension and profit-sharing plans,
Simplified Employee Pension IRAs, 401(k) Plans and 403(b) Plans. Please call the
Fund at (800)  992-3863  to receive  the  appropriate  documents  which  contain
important information and applications.

SYSTEMATIC WITHDRAWAL PLAN

    If your  account is $10,000 or more in any  Portfolio,  you can  establish a
Systematic  Withdrawal  Plan to receive  payments  of at least $50 on a monthly,
quarterly or annual  basis,  without  payment of the CDSC.  The maximum  monthly
withdrawal  is one percent of the current  account value in the Portfolio at the
time you begin participation in the Plan.

REINSTATEMENT PRIVILEGE

    A  shareholder  who has  redeemed  either  Class A or  Class B  shares  of a
Portfolio may, within 30 days of the redemption, reinstate any portion or all of
the net proceeds of such  redemption  in  Portfolio  shares of the same class by
exercise of the Reinstatement  Privilege.  Reinvestment will be at the net asset
value of the Portfolio next  determined  upon receipt of the proceeds and letter
requesting  this  privilege  be  exercised,   subject  to  confirmation  of  the
shareholder's  status or  holdings,  as the case may be. You will also receive a
pro rata credit for any CDSC imposed.  This privilege may be exercised only once
by a shareholder.  Exercising the Reinstatement Privilege will not alter any tax
payable on the redemption and a loss may not be allowed for tax purposes.

                              INVESTMENT OBJECTIVES
                                  AND POLICIES

    The investment objectives and restrictions  summarized below are fundamental
which  means  that they may not be changed  without  shareholder  approval.  All
investment policies and practices described elsewhere in this Prospectus are not
fundamental, so the Fund's Board of Trustees may change them without shareholder
approval.  There  is no  guarantee  that  any  Portfolio's  objectives  will  be
achieved.

    As a matter of fundamental  policy,  no Portfolio  will: (1) with respect to
75% of its total  assets,  invest  more  than 5% of its total  assets in any one
issuer, except for obligations issued or guaranteed by the U.S. Government,  its
agencies or instrumentalities ("U.S. Government securities");  (2) own more than


                                       6
<PAGE>

10% of the outstanding  voting  securities of any company;  (3) invest more than
10% (15% for the Alger  Capital  Appreciation  Portfolio)  of its net  assets in
securities  that are not readily  marketable and in repurchase  agreements  with
maturities of more than seven days; (4) invest more than 25% of its total assets
in any one industry,  except for U.S. Government securities and, with respect to
the Alger Money Market Portfolio, bank and thrift obligations;  (5) borrow money
or pledge its assets,  except for temporary or emergency purposes,  in an amount
not  exceeding  10%  of  its  total  assets;   except  that  the  Alger  Capital
Appreciation  Portfolio  may borrow for  investment  purposes.  The Statement of
Additional  Information contains additional  investment  restrictions as well as
additional information on the Portfolios' investment practices.

    In order to permit  sales of shares in certain  jurisdictions,  the Fund may
commit to policies more  restrictive  than those stated above,  and the Fund may
terminate any such commitment by discontinuing sales of shares in the applicable
jurisdiction.

ALGER MONEY MARKET PORTFOLIO

    The  investment  objective of the  Portfolio is to earn high current  income
consistent  with  preservation  of principal and  maintenance of liquidity.  The
Portfolio may invest in "money market"  instruments  including,  certificates of
deposit,  time deposits and bankers'  acceptances;  U.S. Government  securities;
corporate bonds having less than 397 days remaining to maturity;  and commercial
paper, including variable rate master demand notes. The Portfolio may also enter
into repurchase  agreements,  reverse repurchase  agreements and firm commitment
agreements. The Statement of Additional Information contains more information on
these instruments.

    The  Portfolio  will invest at least 95% of its total assets in money market
securities  which are rated within the highest  credit  category  assigned by at
least two  established  rating agencies (or one rating agency if the security is
rated by only one) and will only invest in money market  securities rated at the
time of purchase  within the two highest  credit  categories or, if not rated of
equivalent  investment  quality as  determined  by Fred Alger  Management,  Inc.
("Alger Management"),  the Fund's investment manager.  Alger Management subjects
all securities  eligible for investment to its own credit analysis and considers
all securities purchased by the Portfolio to present minimal credit risks.

    The Portfolio has a policy of maintaining a stable net asset value of $1.00.
This policy has been maintained since its inception; however, the $1.00 price is
not  guaranteed  or insured,  nor is its yield fixed.  The  Portfolio  generally
purchases  securities which mature in 13 months or less. The average maturity of
the Portfolio will not be greater than 90 days. A discussion of rating  agencies
is included in the Appendix to the Statement of Additional Information.

ALGER BALANCED PORTFOLIO

    The  investment  objective of the Portfolio is current  income and long-term
capital  appreciation.  The  Portfolio  intends  to  invest  based  on  combined
considerations of risk, income,  capital  appreciation and protection of capital
value.  Normally,  it will invest in common  stocks and  investment  grade fixed
income securities  (preferred stock and debt securities),  as well as securities
convertible into common stocks.  Except during temporary defensive periods,  the
Portfolio will maintain at least 25% of its net assets in fixed income  (senior)
securities.  With respect to debt securities,  the Portfolio will invest only in
instruments  which are rated in one of the four highest rating categories by any
established  rating  agency,  or if not  rated,  which are  determined  by Alger
Management to be of comparable quality to instruments so rated.

    The  Portfolio  may  invest  up to 35% of its total  assets in money  market
instruments  and repurchase  agreements and in excess of that amount (up to 100%
of its assets) during temporary defensive periods.

ALGER GROWTH PORTFOLIO

    The investment objective of the Portfolio is long-term capital appreciation.
Except during temporary defensive periods, the Portfolio invests at least 65% of
its total assets in equity securities of companies that, at the time of purchase
of the securities,  have total market  capitalization--present  market value per


                                       7
<PAGE>

share  multiplied  by the total number of shares  outstanding--of  $1 billion or
greater.  The  Portfolio  may  invest  up to 35% of its  total  assets in equity
securities  of  companies  that,  at the time of  purchase,  have  total  market
capitalization of less than $1 billion.

ALGER MIDCAP GROWTH PORTFOLIO

    The investment objective of the Portfolio is long-term capital appreciation.
Except during temporary defensive periods, the Portfolio invests at least 65% of
its total assets in equity securities of companies that, at the time of purchase
of the  securities,  have  total  market  capitalization  within  the  range  of
companies  included  in the S&P  MidCap 400 Index,  updated  quarterly.  The S&P
MidCap 400 Index is designed to track the  performance of medium  capitalization
companies. As of September 30, 1996, the range of market capitalization of these
companies was $177 million to $6.26 billion.  The Portfolio may invest up to 35%
of its total  assets in equity  securities  of  companies  that,  at the time of
purchase,  have  total  market  capitalization  outside  the range of  companies
included in the S&P MidCap 400 Index and in excess of that amount (up to 100% of
its assets) during temporary defensive periods.

ALGER SMALL CAPITALIZATION PORTFOLIO

   
    The investment objective of the Portfolio is long-term capital appreciation.
Except during temporary defensive periods, the Portfolio invests at least 65% of
its total assets in equity securities of companies that, at the time of purchase
of the  securities,  have  total  market  capitalization  within  the  range  of
companies included in the Russell 2000 Growth Index ("Russell Index") or the S&P
SmallCap  600 Index ("S&P  Index"),  updated  quarterly.  Both indexes are broad
indexes of small  capitalization  stocks. As of September 30, 1996, the range of
market  capitalization  of the companies in the Russell Index was $50 million to
$1.78 billion;  the range of market  capitalization  of the companies in the S&P
Index at that date was $36 million to $2.44  billion.  The combined  range as of
that date was $36 million to $2.44  billion.  The Portfolio may invest up to 35%
of its total  assets in equity  securities  of  companies  that,  at the time of
purchase,  have total market capitalization  outside this combined range, and in
excess of that  amount (up to 100% of its  assets)  during  temporary  defensive
periods.
    

ALGER CAPITAL APPRECIATION PORTFOLIO

    The investment objective of the Portfolio is long-term capital appreciation.
Except during temporary defensive periods, the Portfolio invests at least 85% of
its net assets in equity securities of companies of any size.

    The  Portfolio  may purchase  put and call options and sell (write)  covered
call and put options on securities and  securities  indexes to increase gain and
to hedge against the risk of  unfavorable  price  movements,  and may enter into
futures  contracts  on  securities  indexes and  purchase  and sell call and put
options  on  these  futures  contracts.  The  Portfolio  may also  borrow  money
(leverage) for the purchase of additional  securities.  The Portfolio may borrow
only from banks and may not borrow in excess of one-third of the market value of
its total assets,  less liabilities  other than such borrowing.  These practices
are deemed to be speculative and may cause the Portfolio's net asset value to be
more  volatile  than the net asset value of a fund that does not engage in these
activities. See "Investment Practices."

IN GENERAL

    The Alger Small  Capitalization  Portfolio,  Alger MidCap Growth  Portfolio,
Alger Growth Portfolio,  Alger Capital  Appreciation  Portfolio,  and the equity
portion  of  Alger  Balanced  Portfolio  seek to  achieve  their  objectives  by
investing  in  equity  securities,  such  as  common  or  preferred  stocks,  or
securities  convertible  into or exchangeable for equity  securities,  including
warrants and rights.  The Portfolios  will invest  primarily in companies  whose
securities  are traded on domestic  stock  exchanges or in the  over-the-counter
market.  These companies may still be in the  developmental  stage, may be older
companies  that  appear to be entering a new stage of growth  progress  owing to


                                       8
<PAGE>

factors such as management changes or development of new technology, products or
markets or may be  companies  providing  products or  services  with a high unit
volume growth rate. In order to afford the  Portfolios  the  flexibility to take
advantage  of  new  opportunities  for  investments  in  accordance  with  their
investment  objectives,  they may hold up to 15  percent  of their net assets in
money market instruments and repurchase  agreements and in excess of that amount
(up to 100% of their assets) during temporary defensive periods. This amount may
be  higher  than  that  maintained  by  other  funds  with  similar   investment
objectives.

    Investing in smaller,  newer issuers  generally  involves  greater risk than
investing  in larger,  more  established  issuers.  Companies in which the Alger
Small  Capitalization  Portfolio  is likely to invest may have  limited  product
lines,  markets  or  financial  resources  and may lack  management  depth.  The
securities in such companies may have limited  marketability  and may be subject
to more abrupt or erratic  market  movements  than  securities  of larger,  more
established  companies  or the  market  averages  in  general.  Accordingly,  an
investment in the  Portfolio may not be  appropriate  for all  investors.  These
risks may also apply to  investments  in  developmental  stage  companies by the
Alger MidCap Growth Portfolio,  the Alger Growth Portfolio and the Alger Capital
Appreciation Portfolio.

                              INVESTMENT PRACTICES

    The Portfolios may use the investment  strategies and invest in the types of
securities  described  below,  which may involve certain risks. The Statement of
Additional  Information contains more detailed information about these practices
and information about other investment practices of the Portfolios.

REPURCHASE AGREEMENTS

    In a  repurchase  agreement,  a  Portfolio  buys a security at one price and
simultaneously  agrees  to sell it back at a  higher  price.  In the  event of a
bankruptcy  or  default  of the other  party to the  repurchase  agreement,  the
Portfolio  could  experience  costs and  delays in  liquidating  the  underlying
security,  which is held as collateral,  and the Portfolio might incur a loss if
the value of the collateral held declines during this period.

ILLIQUID AND RESTRICTED SECURITIES

    Under  the  policies  and  procedures  established  by the  Fund's  Board of
Trustees,   Alger  Management   determines  the  liquidity  of  the  Portfolios'
investments.  Investments  may be  illiquid  because of the absence of an active
trading  market,  making it difficult to sell promptly at an  acceptable  price.
Each  Portfolio may purchase  securities  eligible for resale under Rule 144A of
the Securities Act of 1933. This rule permits otherwise restricted securities to
be sold to certain  institutional  buyers.  The Fund will limit its purchases of
these securities to those which Alger  Management,  under the supervision of the
Fund's Board of Trustees,  determines to be liquid. A restricted security is one
that  has a  contractual  restriction  on its  resale  or which  cannot  be sold
publicly until it is registered under the Securities Act of 1933.

LENDING OF PORTFOLIO SECURITIES

    In order to generate income and to offset expenses,  each Portfolio may lend
portfolio  securities with a value up to 33 1/3% of the Portfolio's total assets
to brokers,  dealers and other  financial  organizations.  Any such loan will be
continuously secured by collateral at least equal to the value of the securities
loaned. Such lending could result in delays in receiving  additional  collateral
or in the  recovery  of  the  securities  or  possible  loss  of  rights  in the
collateral should the borrower fail financially.

FOREIGN SECURITIES

    Each Portfolio other than the Alger Money Market  Portfolio may invest up to
20% of its total  assets in  foreign  securities.  Investing  in  securities  of
foreign  companies and foreign  governments,  which generally are denominated in
foreign currencies,  may involve certain risk and opportunity considerations not
typically  associated  with investing in domestic  companies and could cause the
Portfolio  to be  affected  favorably  or  unfavorably  by changes  in  currency
exchange rates and revaluations of currencies.



                                       9
<PAGE>

    Each Portfolio may purchase  American  Depositary  Receipts ("ADRs") or U.S.
dollar-denominated  securities  of foreign  issuers that are not included in the
20% foreign  securities  limitation.  ADRs are receipts  issued by U.S. banks or
trust  companies in respect of securities of foreign issuers held on deposit for
use  in  the  U.S.  securities  markets.  While  ADRs  may  not  necessarily  be
denominated  in the same  currency  as the  securities  into  which  they may be
converted,  many of the risks associated with foreign  securities may also apply
to ADRs.

LEVERAGE THROUGH BORROWING

    The Alger Capital Appreciation Portfolio may borrow money from banks and use
it to purchase  additional  securities.  This  borrowing is known as leveraging.
Leverage  increases both  investment  opportunity  and  investment  risk. If the
investment gains on securities purchased with borrowed money exceed the interest
paid on the borrowing,  the net asset value of the Portfolio's  shares will rise
faster than would  otherwise be the case. On the other hand,  if the  investment
gains fail to cover the cost (including interest) of borrowings, or if there are
losses,  the net asset value of the Portfolio's shares will decrease faster than
would  otherwise be the case.  The Portfolio is required to maintain  continuous
asset coverage (that is, total assets  including  borrowings,  less  liabilities
exclusive of borrowings) of 300% of the amount borrowed.  If such asset coverage
should decline below 300% as a result of market  fluctuations  or other reasons,
the  Portfolio  may be required to sell some of its  portfolio  holdings  within
three days to reduce the debt and restore the 300% asset  coverage,  even though
it may be  disadvantageous  from an investment  standpoint to sell securities at
that time.

OPTIONS

    The Alger Capital  Appreciation  Portfolio may buy and sell (write) exchange
listed options in order to obtain additional return or to hedge the value of its
portfolio.  The  Portfolio  may write covered call options only if the Portfolio
owns the  securities on which the call is written or owns  securities  which are
exchangeable or convertible  into such  securities.  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 on
an  exchange  will  exist for any  particular  option.  The  Portfolio  will not
purchase options if, as a result, the aggregate cost of all outstanding  options
exceeds 10% of the  Portfolio's  total assets,  although no more than 5% will be
committed to transactions entered into for non-hedging  purposes.  The Portfolio
may purchase and sell put and call options on stock indexes in order to increase
its gross income or to hedge its portfolio against price fluctuations.

    The writing and purchase of options is a highly  specialized  activity which
involves  investment  techniques and risks different from those  associated with
ordinary portfolio securities transactions. Additional discussion of these risks
and techniques is included in the Statement of Additional Information.

STOCK INDEX FUTURES AND OPTIONS ON
STOCK INDEX FUTURES

    The Alger Capital  Appreciation  Portfolio may purchase and sell stock index
futures  contracts  and  options  on  stock  index  futures   contracts.   These
investments may be made only for hedging,  not  speculative,  purposes.  Hedging
transactions are made to reduce the risk of price fluctuations.

    There can be no assurance of the  Portfolio's  successful use of stock index
futures as a hedging device.  If Alger  Management uses a hedging  instrument at
the wrong time or judges market conditions  incorrectly,  hedging strategies may
reduce the Portfolio's return. The Portfolio could also experience losses if the
prices of its futures and options  positions were not correlated  with its other
investments  or if it could not  close out a  position  because  of an  illiquid
market for the future or option.

PORTFOLIO TURNOVER

    Portfolio  changes will  generally  be made without  regard to the length of
time a  security  has been held or  whether a sale  would  result in a profit or
loss. Higher levels of portfolio activity generally result in higher transaction
costs and may also result in taxes on realized  capital gains to be borne by the
Portfolio's shareholders.

                             MANAGEMENT OF THE FUND

ORGANIZATION

    The Fund was  organized  on March 20, 1986 as a  multi-series  Massachusetts
business  trust.  The Fund offers an  unlimited  number of shares of six series,
representing  the  shares of the  Portfolios.  With the  exception  of the Money
Market Portfolio, each Portfolio offers two classes of shares.

    Although  the  Fund  is  not  required  by law to  hold  annual  shareholder
meetings,  it may hold  meetings  from time to time on  important  matters,  and
shareholders  have the  right to call a meeting  to remove a Trustee  or to take
other action described in the Trust's Declaration of Trust.  Shareholders of one
Portfolio may vote only on matters that affect that Portfolio. Shareholders of a
Class have exclusive voting rights with respect to a matters affecting only that
Class,  and  shareholders  vote  separately  by Class on  matters  in which  the
interests of one Class differ from those of another.

BOARD OF TRUSTEES

    The  Fund is  governed  by a Board of  Trustees  which  is  responsible  for
protecting the interests of shareholders under  Massachusetts law. The Statement
of Additional  Information  contains general  background  information about each
Trustee and officer of the Fund.

INVESTMENT MANAGER

    Alger Management is the Fund's investment manager and is responsible for the
overall  administration of the Fund,  subject to the supervision of the Board of
Trustees. Alger Management makes investment decisions for the Portfolios, places
orders to purchase and sell  securities on behalf of the  Portfolios and selects
broker-dealers  that, in its judgment,  provide prompt and reliable execution at
favorable prices and reasonable  commission  rates. It is anticipated that Alger
Inc.  will  serve as the Fund's  broker in  effecting  substantially  all of the
Portfolios'  transactions on securities exchanges and will retain commissions in
accordance with certain  regulations of the Securities and Exchange  Commission.
The Fund will  consider  sales of its  shares as a factor  in the  selection  of
broker-dealers to execute  over-the-counter  portfolio transactions,  subject to
the  requirements  of best price and execution.  In addition,  Alger  Management
employs   professional   securities   analysts  who  provide  research  services
exclusively to the  Portfolios and other accounts for which Alger  Management or
its affiliates serve as investment adviser or subadviser.

    Alger Management has been in the business of providing  investment  advisory
services since 1964 and, as of November 30, 1996, had approximately $7.2 billion
under management, $4.5 billion in mutual fund accounts and $2.7 billion in other
advisory  accounts.  Alger  Management  is owned by Alger Inc.  which in turn is
owned by Alger Associates,  Inc., a financial services holding company.  Fred M.
Alger,  III and his brother,  David D. Alger,  are the majority  shareholders of
Alger  Associates,  Inc.  and may be  deemed to  control  that  company  and its
subsidiaries.

PORTFOLIO MANAGERS

    David D. Alger, Seilai Khoo and Ronald Tartaro are primarily responsible for
the  day-to-day  management of the  Portfolios  of the Fund.  Mr. Alger has been
employed  by Alger  Management  as  Executive  Vice  President  and  Director of
Research  since 1971 and as President  since 1995. Ms. Khoo has been employed by
Alger  Management as a senior  research  analyst since 1989 and as a Senior Vice
President  since 1995.  Mr.  Tartaro has been employed by Alger  Management as a
senior  research  analyst since 1990 and as a Senior Vice President  since 1995.
Mr. Alger,  Ms. Khoo and Mr. Tartaro also serve as portfolio  managers for other
mutual funds and  investment  accounts  managed by Alger  Management.  Steven R.
Thumm serves as co-manager of the Alger Balanced Portfolio. He has been employed
by Alger  Management  as a fixed income  analyst since 1991 and prior to that he
was employed by Marine Midland Bank as Assistant Vice President.

    Alger  Management  personnel  ("Access  Persons") are permitted to engage in
personal securities  transactions  subject to the restrictions and procedures of
the  Fund's  Code of Ethics.  Pursuant  to the Code of  Ethics,  Access  Persons


                                       11
<PAGE>

generally must preclear all personal  securities  transactions  prior to trading
and are subject to certain  prohibitions on personal trading. You can get a copy
of the Fund's Code of Ethics by calling the Fund toll-free at (800) 992-3863.

FEES AND EXPENSES

    Each  Portfolio  pays Alger  Management a management  fee computed daily and
paid monthly at annual rates based on a percentage  of the value of the relevant
Portfolio's   average  daily  net  assets,   as  follows:   Alger  Money  Market
Portfolio-.50%;   Alger  Small   Capitalization   Portfolio  and  Alger  Capital
Appreciation  Portfolio-.85%;  Alger MidCap Growth Portfolio-.80%;  Alger Growth
Portfolio and Alger Balanced  Portfolio-.75%.  The  management  fees paid by the
Alger Small  Capitalization  Portfolio,  the Alger MidCap Growth Portfolio,  the
Alger Growth  Portfolio,  the Alger  Balanced  Portfolio  and the Alger  Capital
Appreciation  Portfolio  are higher  than  those  paid by most other  investment
companies.

    Each Portfolio pays other expenses related to its daily operations,  such as
custodian fees,  Trustees' fees, transfer agency fees, legal and auditing costs.
More information  about each  Portfolio's  investment  management  agreement and
other expenses paid by the Portfolios is included in the Statement of Additional
Information.

    The  Statement of  Additional  Information  contains  information  about the
Fund's brokerage policies and practices.

DISTRIBUTOR

    Alger Inc. serves as the Fund's  distributor and also distributes the shares
of other mutual funds managed by Alger Management.

TRANSFER AGENT

    Alger Shareholder Services,  Inc., an affiliate of Alger Management,  serves
as  transfer  agent for the Fund.  Certain  record-keeping  services  that would
otherwise be performed by Alger Shareholder  Services,  Inc. may be performed by
other entities  providing  similar services to their customers who invest in the
Portfolios. The Fund, Alger Shareholder Services, Inc., Alger Inc. or any of its
affiliates may elect to enter into a contract to pay them for such services.

SHAREHOLDER SERVICING AGREEMENT

    The Fund pays Alger Inc. a shareholder  servicing fee of .25% of the average
daily net assets of each Portfolio  other than the Alger Money Market  Portfolio
for ongoing  service and  maintenance of shareholder  accounts.  Alger Inc. will
compensate dealers from this fee who provide personal service and maintenance of
customer accounts.

                                 NET ASSET VALUE

   
    The price of one share of a Class is based on its "net asset value." The net
asset value is computed by adding the value of the Portfolio's  investments plus
cash and other assets  allocable to the Class,  deducting  liabilities  and then
dividing the result by the number of its shares outstanding.  Net asset value is
calculated  on each day the New York Stock  Exchange  is open as of the close of
business  (normally  4:00 p.m.  Eastern  time) or,  for the Alger  Money  Market
Portfolio, as of 12:00 noon Eastern time.
    

    Purchases for the Alger Money Market  Portfolio will be processed at the net
asset  value  calculated  after your order is  received  and  accepted.  If your
purchase  is made by wire and is  received  by 12:00  noon  Eastern  time,  your
account will be credited and begin earning  dividends on the day of receipt.  If
your wire  purchase  is  received  after  12:00 noon  Eastern  time,  it will be
credited and begin  earning  dividends  the next  business  day.  Exchanges  are
credited the day the request is received by mail or telephone, and begin earning
dividends the next business day. If your purchase is made by check, and received
by the close of  business  of the New York Stock  Exchange  (normally  4:00 p.m.
Eastern time), it will be credited and begin earning dividends the next business
day.

   
    Purchases  for the other  Portfolios  will be based  upon the next net asset
value  calculated  for each Class after your order is received and accepted.  If
your purchase is made by check, wire or exchange and is received by the close of
    


                                       12
<PAGE>

business of the New York Stock Exchange  (normally 4:00 p.m. Eastern time), your
account  will be credited on the day of  receipt.  If your  purchase is received
after such time, it will be credited the next business day.

    Third-party   checks   will   not  be   honored   except   in  the  case  of
employer-sponsored  retirement  plans.  You will be  charged a fee for any check
returned by your bank.


                               DIVIDENDS AND TAXES

DIVIDENDS

    Each  Class  will be  treated  separately  in  determining  the  amounts  of
dividends of  investment  income and  distributions  of capital gains payable to
holders  of its  shares.  Dividends  and  distributions  will  be  automatically
reinvested on the payment date in  additional  shares of the Class that paid the
dividend or  distribution  at net asset value,  unless you elected in writing to
have all  dividends  and  distributions  paid in cash or reinvested at net asset
value into  another  identically  registered  Alger  Portfolio  account you have
established.   Shares   purchased   through   reinvestment   of  dividends   and
distributions  are not  subject  to the  contingent  deferred  sales  charge  or
front-end  sales  charge.  Dividends  of the Alger Money  Market  Portfolio  are
declared  daily and paid monthly and those of the other  Portfolios are declared
and paid annually.  Distributions  of any net realized  short-term and long-term
capital  gains  earned by a Portfolio  usually will be made  annually  after the
close of the fiscal year in which the gains are earned.

   
    The Classes of a Portfolio may have  different  dividends  and  distribution
rates. Class A dividends  generally will be greater than those of Class B due to
the 12b-1 expenses  associated with Class B shares.  However,  dividends paid to
each class of shares in a Portfolio  will be declared  and paid at the same time
and will be determined in the same manner as those paid to each other class.
    

TAXES

    Each  Portfolio  intends to qualify  and elect to be treated  each year as a
"regulated  investment  company" for federal  income tax  purposes.  A regulated
investment company is not subject to regular income tax on any income or capital
gains distributed to its shareholders if it, among other things,  distributes at
least 90  percent  of its  investment  company  taxable  income  to them  within
applicable time periods. Each Portfolio is treated as a separate taxable entity,
with the result  that  taxable  dividends  and  distributions  from a  Portfolio
reflect only the income and gains, net of losses, of that Portfolio.

    For federal income tax purposes dividends and distributions from a Portfolio
are taxable to you whether paid in cash or reinvested in additional  shares. You
may also be liable for tax on any gain realized upon the  redemption or exchange
of shares in the Portfolios.

    Shortly after the close of each calendar  year, you will receive a statement
setting  forth the dollar  amounts of dividends  and any  distributions  for the
prior  calendar year and the tax status of the dividends and  distributions  for
federal  income tax purposes.  You should consult your tax adviser to assess the
federal,  state and local tax consequences of investing in each Portfolio.  This
discussion is not intended to address the tax consequences of an investment by a
nonresident alien.

                                   PERFORMANCE

    The Portfolios and their  underlying  classes  advertise  different types of
yield  and  total  return  performance.  All  performance  figures  are based on
historical  earnings  and are  not  intended  to  indicate  future  performance.
However,  both yield and total return figures for Class A shares ordinarily will
be different  from those of Class B shares of a portfolio.  Further  information
about the Fund's  performance is contained in its Annual Report to Shareholders,
which may be obtained without charge by contacting the Fund.


                                       13
<PAGE>

    The Alger Money Market  Portfolio may  advertise its "yield" and  "effective
yield."  The  "yield"  of the  Portfolio  refers to the income  generated  by an
investment in the Portfolio over a particular  base period.  This income is then
"annualized."  That is, the amount of income generated by the investment  during
the period is assumed to be  generated  over a 52 week  period and is shown as a
percentage of the investment. The "effective yield" is calculated similarly but,
when annualized,  the income earned by an investment in the Portfolio is assumed
to be reinvested. The "effective yield" will be slightly higher than the "yield"
because of the compounding effect on this assumed reinvestment.

   
    Each of the  Classes of the  Portfolios  other than the Alger  Money  Market
Portfolio may also include  quotations of their "total return" in advertisements
or reports to shareholders or prospective  investors.  Total return figures show
the aggregate or average  percentage change in value of an investment in a Class
from the  beginning  date of the  measuring  period to the end of the  measuring
period.  These  figures  reflect  changes in the price of the Class'  shares and
assume that any income dividends and/or capital gains  distributions made by the
Class during the period were reinvested in shares of the Class.  Figures will be
given for recent 1, 5, and 10 year  periods,  and may be given for other periods
as  well  (such  as  from  commencement  of  the  Class'  operations,  or  on  a
year-by-year  basis) and may utilize dollar cost  averaging.  The Class may also
use  "aggregate"  total return  figures for various  periods,  representing  the
cumulative change in value of an investment in the Class for the specific period
(again  reflecting  changes in Class share price and  assuming  reinvestment  of
dividends and  distributions) as well as "actual annual" and "annualized"  total
return  figures.  Total  returns  may be  calculated  either with or without the
effect of the CDSC or initial  sales  charge to which the shares are subject and
may be shown by means of schedules, charts or graphs, and may indicate subtotals
of the various  components  of total  return  (i.e.,  change in value of initial
investment,  income dividends and capital gains  distributions).  "Total return"
and  "yield"  for a Class will vary based on  changes in market  conditions.  In
addition,  since the  deduction  of a Class'  expenses is reflected in the total
return and yield figures, "total return" and "yield" will also vary based on the
level of the Class' expenses.
    

    The Statement of Additional Information, which is incorporated by reference,
further  describes  the method  used to  determine  the yields and total  return
figures.  Current  yield  and/or  total  return  quotations  may be  obtained by
contacting the Fund.

INVESTMENT OBJECTIVES AND POLICIES

Certain Securities and Investment Techniques

The  Prospectus  discusses the  investment  objectives of each Portfolio and the
policies to be employed  to achieve  those  objectives.  This  section  contains
supplemental   information   concerning   the  types  of  securities  and  other
instruments  in which the Portfolios  may invest,  the  investment  policies and
portfolio strategies that the Portfolios may utilize and certain risks attendant
to those investments, policies and strategies.

U.S. Government Obligations

Bills,  notes,  bonds, and other debt securities issued by the U.S. Treasury are
direct  obligations  of the U.S.  Government  and differ mainly in the length of
their maturities.

U.S. Government Agency Securities

These  securities  are  issued  or  guaranteed  by  U.S.  Government   sponsored
enterprises and federal agencies. These include securities issued by the Federal
National Mortgage Association, Government National Mortgage Association, Federal
Home Loan Bank,  Federal  Land Banks,  Farmers  Home  Administration,  Banks for
Cooperatives,  Federal  Intermediate Credit Banks,  Federal Financing Bank, Farm
Credit Banks, the Small Business Administration,  Federal Housing Administration
and Maritime Administration.  Some of these securities are supported by the full
faith and credit of the U.S.  Treasury;  and the remainder are supported only by
the credit of the instrumentality, which may or may not include the right of the
issuer to borrow from the Treasury.

Bank Obligations

These are certificates of deposit,  bankers'  acceptances,  and other short-term
debt  obligations.   Certificates  of  deposit  are  short-term  obligations  of
commercial  banks.  A bankers'  acceptance is a time draft drawn on a commercial
bank  by  a  borrower,  usually  in  connection  with  international  commercial
transactions. Certificates of deposit may have fixed or variable rates.

The  Portfolios  will not invest in any  security  issued by a  commercial  bank
unless (i) the bank has total assets of at least $1 billion,  or the  equivalent
in other  currencies,  or, in the case of domestic banks which do not have total
assets of at least $1 billion,  the  aggregate  investment  made in any one such
bank is limited to  $100,000  and the  principal  amount of such  investment  is
insured in full by the Federal Deposit Insurance Corporation (ii) in the case of
U.S.  banks, it is a member of the Federal Deposit  Insurance  Corporation,  and
(iii) in the case of  foreign  banks,  the  security  is, in the  opinion of the
Fund's investment  manager,  of an investment  quality  comparable to other debt
securities  which may be purchased by the Portfolios.  These  limitations do not
prohibit  investments in securities  issued by foreign  branches of U.S.  banks,
provided such U.S. banks meet the foregoing requirements.

Foreign Bank Obligations

Investments by the  Portfolios in foreign bank  obligations  and  obligations of
foreign  branches of domestic banks present certain risks,  including the impact
of future  political  and  economic  developments,  the possible  imposition  of
withholding taxes on interest income, the possible seizure or nationalization of
foreign  deposits,  the possible  establishment of exchange  controls and/or the
addition of other foreign governmental  restrictions that might affect adversely
the payment of principal and interest on these obligations.  In addition,  there
may be less  publicly  available and reliable  information  about a foreign bank
than about domestic banks owing to different accounting, auditing, reporting and
recordkeeping standards. In view of these risks, Alger Management will carefully
evaluate these investments on a case-by-case basis.

Short-term Corporate Debt Securities

These are outstanding  nonconvertible corporate debt securities (e.g., bonds and
debentures)  which have one year or less remaining to maturity.  Corporate notes
may have fixed, variable, or floating rates.

Commercial Paper

These are  short-term  promissory  notes  issued by  corporations  primarily  to
finance short-term credit needs.

Variable Rate Master Demand Notes

These are unsecured instruments that permit the indebtedness  thereunder to vary
and provide for periodic  adjustments in the interest rate.  Because these notes
are direct lending  arrangements  between the Portfolio and the issuer, they are
not normally  traded.  Although no active  secondary  market may exist for these
notes, the Portfolio may demand payment of principal and accrued interest at any
time or may resell the note to a third party.  While the notes are not typically
rated by credit  rating  agencies,  issuers of variable rate master demand notes
must satisfy Fred Alger  Management,  Inc.  ("Alger  Management")  that the same
criteria for issuers of commercial  paper are met. In addition,  when purchasing
variable rate master demand notes,  Alger  Management  will consider the earning
power,  cash flows and other  liquidity  ratios of the  issuers of the notes and

                                      -2-
<PAGE>

will continuously  monitor their financial status and ability to meet payment on
demand.  In the event an issuer of a variable rate master demand note  defaulted
on its payment obligations, the Portfolio might be unable to dispose of the note
because of the  absence  of a  secondary  market  and  could,  for this or other
reasons, suffer a loss to the extent of the default.

Repurchase Agreements

Under the terms of a  repurchase  agreement,  a Portfolio  would  acquire a high
quality money market  instrument for a relatively short period (usually not more
than one week)  subject to an obligation  of the seller to  repurchase,  and the
Portfolio  to resell,  the  instrument  at an agreed  price  (including  accrued
interest) and time, thereby determining the yield during the Portfolio's holding
period.  Repurchase  agreements  may  be  seen  to be  loans  by  the  Portfolio
collateralized by the underlying instrument. This arrangement results in a fixed
rate of return that is not subject to market fluctuations during the Portfolio's
holding  period  and  not  necessarily  related  to the  rate of  return  on the
underlying instrument. The value of the underlying securities, including accrued
interest,  will be at  least  equal  at all  times to the  total  amount  of the
repurchase  obligation,  including interest. A Portfolio bears a risk of loss in
the  event  that the  other  party to a  repurchase  agreement  defaults  on its
obligations  and the Portfolio is delayed in or prevented  from  exercising  its
rights to dispose of the collateral securities, including the risk of a possible
decline in the value of the underlying securities during the period in which the
Portfolio  seeks  to  assert  these  rights,  the  risk  of  incurring  expenses
associated with asserting these rights and the risk of losing all or part of the
income from the agreement. Alger Management, acting under the supervision of the
Fund's  Board of  Trustees,  reviews  the credit  worthiness  of those banks and
dealers with which the Portfolios  enter into repurchase  agreements to evaluate
these risks and monitors on an ongoing basis the value of the securities subject
to repurchase  agreements to ensure that the value is maintained at the required
level.

Reverse Repurchase Agreements (Alger Money 
Market Portfolio and Alger Balanced Portfolio)

Reverse repurchase agreements are the same as repurchase agreements except that,
in this instance,  the Portfolio would assume the role of seller/borrower in the
transaction.  The Portfolio  will maintain  segregated  accounts with the Fund's
custodian  consisting  of  U.S.  Government  securities,  cash or  money  market
instruments that at all times are in an amount equal to their  obligations under
reverse repurchase  agreements.  The Portfolio will invest the proceeds in other
money market  instruments or repurchase  agreements  maturing not later than the
expiration of the reverse repurchase  agreement.  Reverse repurchase  agreements
involve the risk that the market value of the  securities  sold by the Portfolio
may decline below the repurchase  price of the securities.  Under the Investment
Company Act of 1940, as amended (the "Act"),  reverse repurchase  agreements may
be considered  borrowings by the seller;  accordingly,  the Portfolio will limit
its investments in reverse repurchase agreements and other borrowings to no more
than one-third of its total assets.

Firm Commitment Agreements and
When-Issued Purchases (Alger Money Market 
Portfolio and the Alger Balanced Portfolio)

Firm commitment agreements and "when-issued"  purchases call for the purchase of
securities at an agreed price on a specified  future date and would be used, for
example,  when a  decline  in the  yield  of  securities  of a given  issuer  is
anticipated  and a  more  advantageous  yield  may  be  obtained  by  committing
currently  to  purchase  securities  to be  issued  later.  When  the  Portfolio
purchases a security under a firm commitment agreement or on a when-issued basis
it assumes the risk of any decline in value of the  security  occurring  between
the  date  of  the  agreement  or  purchase  and  the  settlement  date  of  the
transaction.  The  Portfolio  will not use  these  transactions  for  leveraging
purposes and, accordingly, will segregate with the Fund's custodian cash or high
quality money market  instruments  in an amount  sufficient at all times to meet
its purchase obligations under these agreements.

Warrants and Rights

Each  Portfolio  may  invest in  warrants  and  rights.  A warrant  is a type of
security that entitles the holder to buy a proportionate  amount of common stock
at a  specified  price,  usually  higher  than the  market  price at the time of
issuance,  for a period of years or to perpetuity.  In contrast,  rights,  which
also  represent the right to buy common  shares,  normally  have a  subscription
price lower than the current  market value of the common stock and a life of two
to four  weeks.  Warrants  are freely  transferable  and are traded on the major
securities exchanges.

Restricted Securities

Each Portfolio may invest in restricted securities issued under Rule 144A of the
Securities  Act of 1933.  In adopting  Rule 144A,  the  Securities  and Exchange
Commission specifically stated that restricted securities traded under Rule 144A
may be treated as liquid for purposes of investment  limitations if the board of

                                      -3-
<PAGE>

trustees  (or the fund's  adviser  acting  subject to the  board's  supervision)
determines that the securities are in fact liquid.  Examples of factors that the
Fund's Board of Trustees will take into account in evaluating the liquidity of a
Rule 144A security,  both with respect to the initial purchase and on an ongoing
basis,  will include,  among others:  (1) the frequency of trades and quotes for
the security; (2) the number of dealers willing to purchase or sell the security
and the number of other potential purchasers;  (3) dealer undertakings to make a
market in the security; and (4) the nature of the security and the nature of the
marketplace trades (e.g., the time needed to dispose of the security, the method
of soliciting  offers,  and the mechanics of transfer).  In accordance with Rule
144A,  the  Board  has  delegated  its  responsibility  to Alger  Management  to
determine the liquidity of each restricted  security  purchased  pursuant to the
Rule, subject to the Board's oversight and review. Because institutional trading
in restricted  securities  is relatively  new, it is not possible to predict how
institutional  markets will  develop.  If  institutional  trading in  restricted
securities  were to decline  to  limited  levels,  the  liquidity  of the Fund's
Portfolio could be adversely affected.

Short Sales

Each Portfolio  other than the Alger Money Market  Portfolio may sell securities
"short  against  the  box."  While a short  sale is the sale of a  security  the
Portfolio  does not own, it is "against  the box" if at all times when the short
position  is open  the  Portfolio  owns an equal  amount  of the  securities  or
securities  convertible into, or exchangeable without further consideration for,
securities of the same issue as the securities sold short.

Lending of Portfolio Securities

Each  Portfolio  may lend  securities  to brokers,  dealers and other  financial
organizations.  The Portfolios will not lend  securities to Alger  Management or
its affiliates.  By lending its securities,  a Portfolio can increase its income
by continuing to receive interest or dividends on the loaned  securities as well
as by either  investing  the cash  collateral  in  short-term  securities  or by
earning income in the form of interest paid by the borrower when U.S. Government
securities are used as  collateral.  Each Portfolio will adhere to the following
conditions whenever its securities are loaned: (a) the Portfolio must receive at
least 100 percent cash  collateral or equivalent  securities  from the borrower;
(b) the borrower must increase this collateral  whenever the market value of the
securities  including accrued interest exceeds the value of the collateral;  (c)
the Portfolio  must be able to terminate the loan at any time; (d) the Portfolio
must receive reasonable interest on the loan, as well as any dividends, interest
or other  distributions  on the loaned  securities  and any  increase  in market
value;  (e) the Portfolio may pay only  reasonable  custodian fees in connection
with the loan;  and (f) voting rights on the loaned  securities  may pass to the
borrower;  provided,  however,  that if a material event adversely affecting the
investment  occurs,  the Fund's Board of Trustees  must  terminate  the loan and
regain the right to vote the securities. A Portfolio bears a risk of loss in the
event  that  the  other  party  to a  stock  loan  transaction  defaults  on its
obligations  and the Portfolio is delayed in or prevented  from  exercising  its
rights to dispose of the collateral  including the risk of a possible decline in
the value of the collateral  securities during the period in which the Portfolio
seeks to assert these rights,  the risk of incurring  expenses  associated  with
asserting  these  rights and the risk of losing all or a part of the income from
the transaction.

Foreign Securities

Each Portfolio other than the Alger Money Market  Portfolio may invest up to 20%
of the value of its total assets in foreign  securities (not including  American
Depositary Receipts ("ADRs")). Foreign securities investments may be affected by
changes  in  currency  rates  or  exchange  control   regulations,   changes  in
governmental administration or economic or monetary policy (in the United States
and abroad) or changed circumstances in dealing between nations.  Dividends paid
by foreign  issuers may be subject to  withholding  and other foreign taxes that
may decrease the net return on these  investments  as compared to dividends paid
to the Portfolio by domestic corporations.  It should be noted that there may be
less publicly  available  information  about foreign issuers than about domestic
issuers, and foreign issuers are not subject to uniform accounting, auditing and
financial reporting  standards and requirements  comparable to those of domestic
issuers.  Securities  of some foreign  issuers are less liquid and more volatile
than securities of comparable domestic issuers and foreign brokerage commissions
are generally higher than in the United States.  Foreign  securities markets may
also be less liquid,  more volatile and less subject to  government  supervision
than those in the United  States.  Investments  in  foreign  countries  could be
affected  by  other  factors  not  present  in  the  United  States,   including
expropriation,  confiscatory  taxation and potential  difficulties  in enforcing
contractual  obligations.  Securities purchased on foreign exchanges may be held
in custody by a foreign branch of a domestic bank.

Options (Alger Capital Appreciation Portfolio)

A call option is a contract that gives the holder of the option the right to buy
from the writer  (seller) of the call option,  in return for a premium paid, the
security  underlying the option at a specified exercise price at any time during
the term of the option.  The writer of the call option has the  obligation  upon
exercise of the option to deliver the  underlying  security  upon payment of the
exercise  price during the option  period.  A put option is a contract  that, in
return for the premium,  gives the holder of the option the right to sell to the
writer (seller) the underlying  security at a specified price during the term of
the option. The writer of the put, who receives the premium,  has the obligation
to buy the  underlying  security upon exercise at the exercise  price during the
option  period.  

A call option is "covered" if the Portfolio owns the underlying security covered
by the call or has an absolute  and  immediate  right to acquire  that  security
without additional cash consideration (or for additional cash consideration held
in a segregated  account by its custodian)  upon conversion or exchange of other
securities held in its portfolio. A call option is also covered if the Portfolio
holds a call on the same security as the call written  where the exercise  price
of the call  held is (1) equal to or less  than the  exercise  price of the call
written  or (2)  greater  than the  exercise  price of the call  written  if the
difference is maintained by the Portfolio in cash, U.S. Government securities or
other high grade  short-term  obligations in a segregated  account held with its
custodian.  A put option is "covered" if the Portfolio  maintains  cash or other
high grade short-term  obligations with a value equal to the exercise price in a
segregated  account  held with its  custodian,  or else  holds a put on the same
security as the put written where the exercise price of the put held is equal to
or greater than the exercise price of the put written.

If the  Portfolio  has written an option,  it may  terminate  its  obligation by
effecting a closing purchase transaction.  This is accomplished by purchasing an
option of the same series as the option previously  written.  However,  once the
Portfolio has been assigned an exercise notice,  the Portfolio will be unable to
effect a closing purchase transaction. Similarly, if the Portfolio is the holder
of an  option  it may  liquidate  its  position  by  effecting  a  closing  sale
transaction. This is accomplished by selling an option of the same series as the
option  previously  purchased.  There can be no assurance  that either a closing
purchase or sale transaction can be effected when the Portfolio so desires.

The Portfolio  will realize a profit from a closing  transaction if the price of
the transaction is less than the premium  received from writing the option or is
more than the premium paid to purchase the option;  the Portfolio will realize a
loss from a closing transaction if the price of the transaction is less than the
premium paid to purchase the option.  Since call option prices generally reflect
increases in the price of the underlying  security,  any loss resulting from the
repurchase of a call option may also be wholly or partially offset by unrealized
appreciation of the underlying  security.  Other principal factors affecting the
market  value of a put or a call  option  include  supply and  demand,  interest
rates, the current market price and price volatility of the underlying  security
and the time remaining until the expiration date.

An option  position  may be closed  out only on an  exchange  which  provides  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 on
an exchange will exist for any particular  option. In such event it might not be
possible to effect  closing  transactions  in  particular  options,  so that the
Portfolio  would have to exercise  its option in order to realize any profit and
would incur  brokerage  commissions  upon the  exercise of the  options.  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 or otherwise covers the position.

In addition to options on  securities,  the Portfolio may also purchase and sell
call and put options on securities  indexes.  A stock index reflects in a single
number the market value of many different  stocks.  Relative values are assigned
to the stocks included in an index and the index  fluctuates with changes in the
market values of the stocks.  The options give the holder the right to receive a
cash  settlement  during the term of the option based on the difference  between
the exercise  price and the value of the index.  By writing a put or call option
on a securities  index,  the Portfolio is  obligated,  in return for the premium
received, to make delivery of this amount. The Portfolio may offset its position
in  stock  index  options  prior  to  expiration  by  entering  into  a  closing
transaction on an exchange or it may let the option expire unexercised.

Use of  options  on  securities  indexes  entails  the risk that  trading in the
options  may be  interrupted  if trading in certain  securities  included in the
index is interrupted. The Portfolio will not purchase these options unless Alger

                                      -5-
<PAGE>

Management is satisfied with the development,  depth and liquidity of the market
and Alger Management believes the options can be closed out.

Price movements in the Portfolio's  securities may not correlate  precisely with
movements in the level of an index and, therefore, the use of options on indexes
cannot  serve as a complete  hedge and will depend,  in part,  on the ability of
Alger  Management to predict  correctly  movements in the direction of the stock
market  generally or of a particular  industry.  Because  options on  securities
indexes require  settlement in cash, Alger Management may be forced to liquidate
portfolio securities to meet settlement obligations.

The  Portfolio  has qualified and intends to continue to qualify as a "Regulated
Investment  Company" under the Internal  Revenue Code. One  requirement for such
qualification  is that the  Portfolio  must  derive  less  than 30% of its gross
income from gains from the sale or other disposition of securities held for less
than three  months.  Therefore,  the  Portfolio may be limited in its ability to
engage in options transactions.

Although Alger Management will attempt to take appropriate  measures to minimize
the risks relating to the Portfolio's writing of put and call options, there can
be no assurance that the Portfolio will succeed in any option-writing program it
undertakes.

Stock Index Futures and Options on Stock 
Index Futures (Alger Capital Appreciation 
Portfolio)

Futures are generally  bought and sold on the  commodities  exchanges where they
are listed with payment of initial and variation  margin as described below. The
sale of a  futures  contract  creates a firm  obligation  by the  Portfolio,  as
seller,  to deliver to the buyer the net cash amount  called for in the contract
at a specific  future time. Put options on futures might be purchased to protect
against  declines in the market values of securities  occasioned by a decline in
stock prices and  securities  index futures  might be sold to protect  against a
general  decline in the value of securities of the type that comprise the index.
Options on futures contracts are similar to options on securities except that an
option on a futures  contract  gives the  purchaser  the right in return for the
premium paid to assume a position in a futures contract and obligates the seller
to deliver such position.  

A stock index future obligates the seller to deliver (and the purchaser to take)
an amount of cash equal to a specific dollar amount times the difference between
the value of a specific  stock index at the close of the last trading day of the
contract and the price at which the agreement is made.  No physical  delivery of
the underlying  stocks in the index is made.  With respect to stock indexes that
are permitted  investments,  the Portfolio  intends to purchase and sell futures
contracts  on the stock  index  for  which it can  obtain  the best  price  with
considerations  also given to  liquidity.  While  incidental  to its  securities
activities, the Portfolio may use index futures as a substitute for a comparable
market position in the underlying securities.

The risk of imperfect  correlation increases as the composition of the Portfolio
varies from the  composition of the stock index.  In an effort to compensate for
the  imperfect  correlation  of movements in the price of the  securities  being
hedged and movements in the price of the stock index futures,  the Portfolio may
buy or sell stock index  futures  contracts in a greater or lesser dollar amount
than  the  dollar  amount  of the  securities  being  hedged  if the  historical
volatility  of the stock index futures has been less or greater than that of the
securities.  Such "over  hedging" or "under  hedging" may  adversely  affect the
Portfolio's  net investment  results if market  movements are not as anticipated
when the hedge is established.

An option on a stock  index  futures  contract,  as  contrasted  with the direct
investment in such a contract,  gives the purchaser the right, in return for the
premium  paid,  to assume a position  in a stock  index  futures  contract  at a
specified exercise price at any time prior to the expiration date of the option.
The Portfolio will sell options on stock index futures contracts only as part of
closing purchase  transactions to terminate its options positions.  No assurance
can be given that such closing  transactions  can be effected or that there will
be correlation between price movements in the options on stock index futures and
price  movements  in the  Portfolio's  securities  which are the  subject of the
hedge. In addition,  the Portfolio's purchase of such options will be based upon
predictions as to anticipated market trends, which could prove to be inaccurate.

The Portfolio's use of stock index futures and options thereon will in all cases
be consistent  with  applicable  regulatory  requirements  and in particular the
rules and regulations of the Commodity  Futures  Trading  Commission and will be
entered into only for bona fide  hedging,  risk  management  or other  portfolio
management  purposes.  Typically,  maintaining a futures  contract or selling an
option thereon  requires the Portfolio to deposit with a financial  intermediary
as security  for its  obligations  an amount of cash or other  specified  assets
(initial  margin)  which  initially is typically 1% to 10% of the face amount of
the  contract  (but may be higher  in some  circumstances).  Additional  cash or
assets (variation margin) may be required to be deposited  thereafter on a daily
basis as the mark to market value of the contract fluctuates. The purchase of an
option on stock  index  futures  involves  payment  of a premium  for the option

                                      -6-
<PAGE>

without any further  obligation on the part of the  Portfolio.  If the Portfolio
exercises  an option on a futures  contract it will be obligated to post initial
margin (and potential  subsequent  variation  margin) for the resulting  futures
position  just as it would  for any  position.  Futures  contracts  and  options
thereon are generally  settled by entering into an  offsetting  transaction  but
there can be no assurance that the position can be offset prior to settlement at
an advantageous price, nor that delivery will occur.

The Portfolio  will not enter into a futures  contract or related option (except
for closing transactions) if, immediately  thereafter,  the sum of the amount of
its initial  margin and premiums on open futures  contracts and options  thereon
would  exceed 5% of the  Portfolio's  total  assets  (taken at  current  value);
however,  in the  case of an  option  that is  in-the-money  at the  time of the
purchase,  the  in-the-money  amount  may  be  excluded  in  calculating  the 5%
limitation.

Investment Restrictions

The investment restrictions numbered 1 through 12 below have been adopted by the
Fund with respect to each of the Portfolios as fundamental  policies.  Under the
Investment  Company Act of 1940, as amended (the "Act"), a "fundamental"  policy
may not be changed  without the vote of a "majority  of the  outstanding  voting
securities"  of the Fund,  which is  defined  in the Act as the lesser of (a) 67
percent or more of the shares  present at a Fund  meeting if the holders of more
than 50 percent of the outstanding shares of the Fund are present or represented
by proxy or (b) more than 50 percent of the  outstanding  shares.  A fundamental
policy affecting a particular Portfolio may not be changed without the vote of a
majority  of  the  outstanding  voting  securities  of the  affected  Portfolio.
Investment  restrictions  13 through 19 may be changed by vote of a majority  of
the Fund's Board of Trustees at any time.

The investment policies adopted by the Fund prohibit each Portfolio from:

1.  Purchasing  the  securities  of  any  issuer,  other  than  U.S.  Government
securities,  if as a  result  more  than  five  percent  of  the  value  of  the
Portfolio's  total  assets  would be invested in the  securities  of the issuer,
except  that up to 25 percent of the value of the  Portfolio's  (other  than the
Alger Money Market  Portfolio's)  total assets may be invested without regard to
this limitation.

2. Purchasing more than 10 percent of the voting securities of any one issuer or
more than 10  percent of the  securities  of any class of any one  issuer.  This
limitation shall not apply to investments in U.S. Government securities.

3. Selling securities short or purchasing  securities on margin, except that the
Portfolio  may obtain any  short-term  credit  necessary  for the  clearance  of
purchases  and  sales of  securities.  These  restrictions  shall  not  apply to
transactions involving selling securities "short against the box."

4. Borrowing money,  except that (a) all Portfolios other than the Alger Capital
Appreciation   Portfolio  may  borrow  for  temporary  or  emergency   (but  not
leveraging)  purposes  including the meeting of  redemption  requests that might
otherwise  require the  untimely  disposition  of  securities,  in an amount not
exceeding 10 percent of the value of the Portfolio's total assets (including the
amount borrowed)  valued at the lesser of cost or market,  less liabilities (not
including the amount  borrowed) at the time the borrowing is made; (b) the Alger
Money  Market  Portfolio  and  the  Alger  Balanced   Portfolio  may  engage  in
transactions  in  reverse  repurchase  agreements;  and  (c) the  Alger  Capital
Appreciation  Portfolio  may borrow  from banks for  investment  purposes as set
forth in the  Prospectus.  Whenever  borrowings  described  in (a)  exceed  five
percent of the value of the Portfolio's  total assets,  the Portfolio other than
the  Alger  Capital   Appreciation   Portfolio  will  not  make  any  additional
investments.  Immediately  after any  borrowing,  including  reverse  repurchase
agreements,  the  Portfolio  will maintain  asset  coverage of not less than 300
percent with respect to all borrowings.

5. Pledging,  hypothecating,  mortgaging or otherwise  encumbering  more than 10
percent of the value of the  Portfolio's  total assets except in connection with
borrowings  as  noted in 4(c)  above.  These  restrictions  shall  not  apply to
transactions   involving  reverse  repurchase  agreements  or  the  purchase  of
securities subject to firm commitment agreements or on a when-issued basis.

6.  Issuing  senior  securities,  except  that the  Alger  Capital  Appreciation
Portfolio may borrow from banks for investment purposes so long as the Portfolio
maintains the required asset coverage.

7. Underwriting the securities of other issuers, except insofar as the Portfolio
may be deemed to be an underwriter under the Securities Act of 1933, as amended,
by virtue of disposing of portfolio securities.

8. Making loans to others, except through purchasing qualified debt obligations,
lending portfolio securities or entering into repurchase agreements.

9. Investing in securities of other investment companies,  except as they may be
acquired  as part of a merger,  consolidation,  reorganization,  acquisition  of
assets or offer of exchange.

                                      -7-
<PAGE>

10. Purchasing any securities that would cause more than 25 percent of the value
of the  Portfolio's  total  assets to be invested in the  securities  of issuers
conducting their principal  business  activities in the same industry;  provided
that (a) there shall be no limit on the purchase of U.S. Government  securities,
and (b)  there  shall be no limit on the  purchase  by the  Alger  Money  Market
Portfolio of obligations issued by bank and thrift institutions described in the
Prospectus and this Statement of Additional Information.

11.  Investing  in  commodities,  except  that the  Alger  Capital  Appreciation
Portfolio may purchase or sell stock index futures contracts and related options
thereon if, thereafter,  no more than 5 percent of its total assets are invested
in margin and premiums.

12.  Investing more than 10 percent (15 percent in the case of the Alger Capital
Appreciation  Portfolio) of its net assets in  securities  which are illiquid by
virtue  of legal or  contractual  restrictions  on resale  or the  absence  of a
readily  available  market.  However,   securities  with  legal  or  contractual
restrictions  on resale may be purchased by the Alger Money Market  Portfolio if
they are determined to be liquid, and such purchases would not be subject to the
10  percent  limit  stated  above.  The  Board of  Trustees  will in good  faith
determine the specific types of securities  deemed to be liquid and the value of
such securities held in the Alger Money Market Portfolio. The Alger Money Market
Portfolio  will not purchase time deposits  maturing in more than seven calendar
days and will limit to no more than 10 percent of its assets its  investment  in
time deposits  maturing in excess of two business days,  together with all other
illiquid securities.

13.  Purchasing  or selling  real  estate or real estate  limited  partnerships,
except that the  Portfolio  may  purchase  and sell  securities  secured by real
estate,  mortgages  or  interests  therein  and  securities  that are  issued by
companies that invest or deal in real estate.

14. Writing or selling puts, calls, straddles,  spreads or combinations thereof,
except that the Alger Capital Appreciation Portfolio may invest in options.

15. Investing in oil, gas or other mineral, exploration or development programs,
except that the Portfolio may invest in the  securities of companies that invest
in or sponsor those programs.

16. Purchasing any security if, as a result,  the Portfolio would then have more
than  five  percent  of its total  assets  invested  in  securities  of  issuers
(including  predecessors)  that have been in continual  operation  for less than
three years.  This limitation shall not apply to investments in U.S.  Government
securities.

17. Making investments for the purpose of exercising control or management.

18. Investing in warrants,  except that the Portfolio may invest in warrants if,
as a result,  the investments  (valued at the lower of cost or market) would not
exceed five  percent of the value of the  Portfolio's  net assets,  of which not
more than two percent of the  Portfolio's net assets may be invested in warrants
not listed on a recognized  domestic stock  exchange.  Warrants  acquired by the
Portfolio as part of a unit or attached to securities at the time of acquisition
are not subject to this limitation.

19. Purchasing or retaining the securities of any issuer if, to the knowledge of
the  Fund,  any of the  officers,  directors  or  trustees  of the Fund or Alger
Management  individually owns more than .5 percent of the outstanding securities
of the issuer and together they own  beneficially  more than five percent of the
securities.

As of April  29,  1994,  shares  of the  Alger  Growth  Portfolio,  Alger  Small
Capitalization  Portfolio and Alger MidCap Growth  Portfolio were registered for
sale  in  Germany.   As  long  as  the  Alger  Growth  Portfolio,   Alger  Small
Capitalization  Portfolio  and Alger MidCap Growth  Portfolio are  registered in
Germany, these Portfolios may not without prior approval of their shareholders:

    a. Invest in the  securities  of any other  domestic  or foreign  investment
       company or investment  fund except in connection with a plan of merger or
       consolidation with or acquisition of substantially all the assets of such
       other investment company or investment fund;

    b. Purchase or sell real  estate or any  interest  therein,  and real estate
       mortgage  loans,  except that the  Portfolios may invest in securities of
       corporate or governmental  entities  secured by real estate or marketable
       interests  therein or  securities  issued by  companies  (other than real
       estate  limited  partnerships,  real  estate  investment  trusts and real
       estate funds) that invest in real estate or interests therein;

    c. Borrow  money,  except for  temporary or emergency  (but not  leveraging)
       purposes  including  the  meeting  of  redemption   requests  that  might
       otherwise  require the untimely  disposition of securities,  in an amount
       not  exceeding  10 percent of the value of the  Portfolio's  total assets
       (including the amount  borrowed)  valued at the lesser of cost or market,

                                      -8-
<PAGE>

       less  liabilities  (not  including  the amount  borrowed) at the time the
       borrowing is made;

    d. Pledge, hypothecate, mortgage or otherwise encumber their  assets  except
       to secure indebtedness permitted under section c.;

    e. Purchase securities on margin or make short sales; or;

    f. Redeem their securities in kind.

These Portfolios will comply with the more restrictive  policies required by the
German regulatory  authorities,  as stated above, as long as such Portfolios are
registered in Germany.

Except  in the  case of the 300  percent  limitation  set  forth  in  Investment
Restriction  No.  4,  the  percentage  limitations  contained  in the  foregoing
restrictions  apply at the time of the  purchase of the  securities  and a later
increase or decrease in percentage  resulting from a change in the values of the
securities  or in the amount of the  Portfolio's  assets will not  constitute  a
violation of the restriction.

Portfolio Transactions

Decisions  to buy and sell  securities  and other  financial  instruments  for a
Portfolio are made by Alger  Management,  which also is responsible  for placing
these  transactions,  subject  to the  overall  review  of the  Fund's  Board of
Trustees.  Although  investment  requirements  for each  Portfolio  are reviewed
independently  from those of the other accounts  managed by Alger Management and
those of the other  Portfolios,  investments of the type the Portfolios may make
may also be made by these other accounts or Portfolios. When a Portfolio and one
or more other Portfolios or accounts managed by Alger Management are prepared to
invest  in,  or desire to  dispose  of,  the same  security  or other  financial
instrument,  available  investments or opportunities for sales will be allocated
in a manner believed by Alger Management to be equitable to each. In some cases,
this procedure may affect adversely the price paid or received by a Portfolio or
the size of the position obtained or disposed of by a Portfolio. 

Transactions  in equity  securities  are in many cases  effected  on U. S. stock
exchanges and involve the payment of negotiated brokerage commissions.  There is
generally  no  stated  commission  in  the  case  of  securities  traded  in the
over-the-counter markets, but the prices of those securities include undisclosed
commissions  or mark-ups.  Purchases and sales of money market  instruments  and
debt  securities  usually  are  principal  transactions.  These  securities  are
normally  purchased  directly from the issuer or from an  underwriter  or market
maker for the  securities.  The cost of securities  purchased from  underwriters
includes  an  underwriting  commission  or  concession  and the  prices at which
securities are purchased from and sold to dealers include a dealer's  mark-up or
mark-down. U. S. Government securities are generally purchased from underwriters
or dealers,  although  certain  newly-issued U. S. Government  securities may be
purchased  directly  from the U. S.  Treasury  or from  the  issuing  agency  or
instrumentality.

To the extent consistent with applicable provisions of the Act and the rules and
exemptions  adopted  by the  Securities  and  Exchange  Commission  (the  "SEC")
thereunder,  as well as  other  regulatory  requirements,  the  Fund's  Board of
Trustees has determined  that portfolio  transactions  will be executed  through
Fred Alger & Company,  Incorporated  ("Alger Inc.") if, in the judgment of Alger
Management,  the use of Alger Inc. is likely to result in price and execution at
least  as  favorable  as  those of other  qualified  broker-dealers  and if,  in
particular  transactions,  Alger  Inc.  charges  the  Portfolio  involved a rate
consistent  with that charged to  comparable  unaffiliated  customers in similar
transactions.  Such  transactions will be fair and reasonable to the Portfolio's
shareholders.  Over-the-counter purchases and sales are transacted directly with
principal  market  makers  except  in those  cases in which  better  prices  and
executions may be obtained  elsewhere.  Principal  transactions  are not entered
into with  affiliates of the Fund except  pursuant to exemptive  rules or orders
adopted by the SEC.

In selecting brokers or dealers to execute portfolio transactions on behalf of a
Portfolio, Alger Management seeks the best overall terms available. In assessing
the best overall terms  available for any  transaction,  Alger  Management  will
consider the factors it deems  relevant,  including the breadth of the market in
the  investment,  the  price of the  investment,  the  financial  condition  and
execution  capability  of the  broker or dealer  and the  reasonableness  of the
commission,  if any, for the specific  transaction and on a continuing basis. In
addition,  Alger  Management is  authorized,  in selecting  parties to execute a
particular  transaction and in evaluating the best overall terms  available,  to
consider  the  brokerage  and research  services,  as those terms are defined in
section 28(e) of the Securities  Exchange Act of 1934, provided to the Portfolio
involved, the other Portfolios and/or other accounts over which Alger Management
or its affiliates exercise investment  discretion.  The Fund will consider sales
of its  shares  as a  factor  in the  selection  of  broker-dealers  to  execute
over-the-counter  transactions,  subject to the  requirements  of best price and
execution.  Alger Management's fees under its agreements with the Portfolios are

                                      -9-
<PAGE>

   
not reduced by reason of its  receiving  brokerage  and  research  service.  The
Fund's Board of Trustees will  periodically  review the commissions  paid by the
Portfolios to determine if the commissions paid over  representative  periods of
time are  reasonable  in relation  to the  benefits  inuring to the  Portfolios.
During the fiscal years ended October 31, 1994, 1995, and 1996, the Fund paid an
aggregate of approximately $765,940,  $799,446 and $1,691,123  respectively,  in
commissions to broker-dealers in connection with portfolio transactions, 100% of
which was paid to Alger Inc.,  except  that $2,156 was paid to other  brokers in
1994 and $136,862 was paid to other brokers in 1996.  Alger Inc. does not engage
in  principal   transactions  with  the  Fund  and,  accordingly,   received  no
compensation  in connection  with  securities  purchased or sold in that manner,
which include securities traded in the  over-the-counter  markets,  money market
investments and most debt securities.  
    

NET ASSET VALUE 

The  Prospectus  discusses the time at which the net asset values of the classes
of each Portfolio are determined for purposes of sales and redemptions.  The New
York Stock Exchange is currently open on each Monday through Friday,  except (i)
January  1st,  Presidents'  Day (the third  Monday in  February),  Good  Friday,
Memorial Day (the last Monday in May),  July 4th, Labor Day (the first Monday in
September), Thanksgiving Day (the fourth Thursday in November) and December 25th
and  (ii)  the  preceding  Friday  when  any one of  those  holidays  falls on a
Saturday,  or the  subsequent  Monday when any one of those  holidays falls on a
Sunday.  The following is a description  of the  procedures  used by the Fund in
valuing the Portfolios' assets.

The assets of the  Portfolios  other than the Alger Money Market  Portfolio  are
generally valued on the basis of market  quotations.  Securities whose principal
market is on an  exchange  or in the  over-the-counter  market are valued at the
last  reported  sales price or, in the absence of  reported  sales,  at the mean
between  the bid and asked  price or, in the  absence  of a recent  bid or asked
price,  the  equivalent  as obtained from one or more of the major market makers
for the securities to be valued.  Bonds and other fixed income securities may be
valued on the basis of prices  provided  by a pricing  service  when the  Fund's
Board of Trustees  believes  that these prices  reflect the fair market value of
the  securities.  Other  investments  and  other  assets,  including  restricted
securities and securities for which market quotations are not readily available,
are valued at fair  value  under  procedures  approved  by the  Fund's  Board of
Trustees. Short-term securities with maturities of 60 days or less are valued at
amortized cost, as described below,  which  constitutes fair value as determined
by the Fund's Board of Trustees.

The valuation of the  securities  held by the Alger Money Market  Portfolio,  as
well as money market  instruments with maturities of 60 days or less held by the
other  Portfolios,  is based on their  amortized  cost  which does not take into
account  unrealized  capital gains or losses.  Amortized cost valuation involves
initially  valuing an instrument at its cost and thereafter  assuming a constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument.  Although this
method  provides  certainty in valuation,  it may result in periods during which
value,  as  determined  by amortized  cost,  is higher or lower than the price a
Portfolio would receive if it sold the instrument.

The Alger Money Market  Portfolio's  use of the amortized cost method of valuing
its  securities is permitted by a rule adopted by the SEC.  Under this rule, the
Portfolio must maintain a dollar-weighted  average portfolio maturity of 90 days
or less, purchase only instruments having remaining  maturities of less than 397
days, as determined in accordance  with the  provisions of the rule,  and invest
only in securities determined by Alger Management,  acting under the supervision
of the Fund's  Board of Trustees,  to be of high  quality  with  minimal  credit
risks.

Pursuant  to the  rule,  the  Fund's  Board of  Trustees  also  has  established
procedures designed to stabilize,  to the extent reasonably possible,  the Alger
Money  Market  Portfolio's  price per share as computed for the purpose of sales
and  redemptions at $1.00.  These  procedures  include review of the Portfolio's
holdings  by the  Fund's  Board  of  Trustees,  at such  intervals  as it  deems
appropriate,  to determine whether the Portfolio's net asset value calculated by
using available market quotations or market equivalents  deviates from $1.00 per
share based on amortized cost.

The rule also provides that the extent of any deviation  between the Portfolio's
net asset value based on available market  quotations or market  equivalents and
$1.00 per share net asset value based on amortized  cost must be examined by the
Fund's Board of Trustees.  In the event the Fund's Board of Trustees  determines
that a deviation  exists that may result in  material  dilution or other  unfair
results to investors or existing  shareholders,  pursuant to the rule the Fund's
Board of Trustees must cause the Portfolio to take such corrective action as the
Fund's  Board of  Trustees  regards as  necessary  and  appropriate,  including:

                                      -10-
<PAGE>

selling  portfolio  instruments  prior to maturity to realize  capital  gains or
losses or to shorten average portfolio maturity, withholding dividends or paying
distributions  from  capital  or  capital  gains,  redeeming  shares  in kind or
establishing net asset value per share by using available market quotations.

PURCHASES

Shares  of  the  Portfolios  are  offered  continuously  by  the  Fund  and  are
distributed on a best efforts basis by Alger Inc. as principal  underwriter  for
the Fund pursuant to a distribution  agreement (the  "Distribution  Agreement").
Under  the  Distribution  Agreement,  Alger  Inc.  bears all  selling  expenses,
including the costs of advertising and of printing prospectuses and distributing
them to prospective shareholders.

Distribution Plan

To reimburse Alger Inc. for the distribution expenses it bears in respect of the
Fund's Class B shares, the Fund has adopted an Amended and Restated Distribution
Plan (the "Plan")  pursuant to Rule 12b-1 under the Act.  

Distribution  expenses  covered under the Plan may include  payments made to and
expenses  of  persons  who are  engaged  in,  or  provide  support  services  in
connection  with,  the  distribution  of the class'  shares,  such as  answering
routine telephone  inquiries for prospective  shareholders;  compensation in the
form of sales concessions and continuing compensation paid to securities dealers
whose  customers hold shares of the class;  costs related to the formulation and
implementation  of marketing and promotional  activities,  including direct mail
promotions  and  television,  radio,  newspaper,  magazine  and other mass media
advertising;  costs of printing  and  distributing  prospectuses  and reports to
prospective shareholders of the class; costs involved in preparing, printing and
distributing  sales  literature  for the class;  and costs involved in obtaining
whatever  information,  analyses  and  reports  with  respect to  marketing  and
promotional activities on behalf of the class that the Fund deems advisable.

It is anticipated that  distribution  expenses incurred by Alger Inc. during the
early years of a Portfolio's  Class B share operations will exceed the assets of
the class available for reimbursement  under the Plan, while it is possible that
in later years the converse  may be true.  Distribution  expenses  incurred in a
year in  respect  of Class B shares  of a  Portfolio  in  excess  of  contingent
deferred sales charges received by Alger Inc.  relating to redemptions of shares
of the class  during that year and .75 percent of the class'  average  daily net
assets  may be carried  forward  and sought to be  reimbursed  in future  years.
Interest at the  prevailing  broker  loan rate may be charged to the  applicable
Portfolio's  Class B shares on any expenses  carried  forward and those expenses
and interest will be reflected as current expenses on the Portfolio's  statement
of operations for the year in which the amounts become  accounting  liabilities,
which is  anticipated  to be the year in which these amounts are actually  paid.
Although the Fund's  Board of Trustees  may change this policy,  it is currently
anticipated  that  payments  under the Plan in a year will be  applied  first to
distribution  expenses  incurred in that year and then, up to the maximum amount
permitted  under the Plan,  to  previously  incurred but  unreimbursed  expenses
carried forward plus interest thereon.

Alger Inc.  has  acknowledged  that  payments  under the Plan are subject to the
approval of the Fund's Board of Trustees and that no Portfolio is  contractually
obligated to make payments in any amount or at any time,  including  payments in
reimbursement  of Alger Inc. for expenses  and  interest  thereon  incurred in a
prior year.

Under its terms,  the Plan  remains in effect from year to year,  provided  such
continuance  is  approved  annually  by vote of the  Fund's  Board of  Trustees,
including a majority of the Trustees who are not interested  persons of the Fund
and who have no direct or indirect  financial  interest in the  operation of the
Plan  ("Independent  Trustees").  The  Plan  may  not  be  amended  to  increase
materially  the  amount  to be spent for the  services  provided  by Alger  Inc.
without the approval of Class B shareholders, and all material amendments of the
Plan must also be approved by the Trustees in the manner  described  above.  The
Plan may be terminated at any time,  without  penalty,  by vote of a majority of
the Independent Trustees or, with respect to the Class B shares of any Portfolio
to which the Plan  relates,  by a vote of a majority of the  outstanding  voting
securities  of the class,  on not more than thirty days'  written  notice to any
other party to the Plan. If the Plan is terminated,  or not renewed with respect
to any one or more  Portfolios,  it may  continue in effect with  respect to the
Class B shares of any Portfolio as to which it has not been  terminated,  or has
been renewed. Alger Inc. will provide to the Board of Trustees quarterly reports
of amounts  expended under the Plan and the purpose for which such  expenditures
were made.  During the fiscal year ended October 31, 1996,  the Fund  reimbursed
$7,124,099 to Alger Inc. as the Fund's underwriter,  under the provisions of the
Plan. Alger Inc.'s selling expenses during that period totaled $20,969,782 which
consisted of $1,150,159 in printing and mailing of prospectuses  and other sales
literature to prospective investors;  $2,136,299 in advertising;  $15,253,965 in
compensation to dealers; $638,216 in compensation to sales personnel; $63,496 in

                                      -11-
<PAGE>

other  marketing  expenses;  and  $1,727,647  in  interest,  carrying  or  other
financing  charges.  If in any month,  the costs  incurred by Alger Inc.  are in
excess of the distribution expenses charged to Class B shares of the Portfolios,
the excess may be carried forward, with interest, and sought to be reimbursed in
future  periods.  As of October  31,  1996,  such  excess  carried  forward  was
approximately $7,877,000,  $16,225,000,  $282,000, $3,069,000 and $2,130,000 for
the Class B shares of Alger  Growth  Portfolio,  the Alger Small  Capitalization
Portfolio,  the Alger Balanced Portfolio,  the Alger MidCap Growth Portfolio and
the Alger Capital Appreciation Portfolio, respectively.

Shareholder Servicing Agreement

Payments under the Shareholder  Servicing  Agreement are not tied exclusively to
the  shareholder  servicing  expenses  actually  incurred by Alger Inc.  and the
payments may exceed expenses actually incurred by Alger Inc. The Fund's Board of
Trustees evaluates the  appropriateness of the Shareholder  Servicing  Agreement
and its  payment  terms on a  continuing  basis  and in doing so  considers  all
relevant  factors,  including  expenses  borne by Alger Inc.  and the amounts it
receives under the Shareholder Servicing Agreement.

Expenses of the Fund

   
Each Portfolio will bear its own expenses. Operating expenses for each Portfolio
generally  consist  of all costs  not  specifically  borne by Alger  Management,
including  investment  management  fees,  fees for  necessary  professional  and
brokerage  services,  costs of regulatory  compliance and costs  associated with
maintaining legal existence and shareholder relations.  In addition,  Class B of
each Portfolio  other than the Money Market  Portfolio may reimburse  Alger Inc.
for expenses incurred in distributing Class B shares and each such Portfolio may
compensate Alger Inc. for servicing shareholder accounts.  Fundwide expenses not
identifiable to any particular  Portfolio or Class will be allocated in a manner
deemed fair and  equitable  by the Board of Trustees.  From time to time,  Alger
Management,  in its sole  discretion  and as it deems  appropriate,  may  assume
certain expenses of one or more of the Portfolios while retaining the ability to
be reimbursed by the  applicable  Portfolio for such amounts prior to the end of
the  fiscal  year.  This  will  have  the  effect  of  lowering  the  applicable
Portfolio's  overall expense ratio and of increasing yield to investors,  or the
converse,  at the time such amounts are assumed or  reimbursed,  as the case may
be.
    

Purchases Through Processing Organizations

When shares are purchased this way, the Processing Organization, rather than its
customer,  may be the  shareholder of record of the shares.  The minimum initial
and subsequent  investments in classes of the  Portfolios for  shareholders  who
invest  through  a  Processing  Organization  will  be  set  by  the  Processing
Organization.  Processing  Organizations  may charge  their  customers  a fee in
connection with services offered to customers.  

TelePurchase Privilege 

   
The price the  shareholder  will receive will be the price next  computed  after
Alger Shareholder Services,  Inc. (the "Transfer Agent") receives the investment
from the  shareholder's  bank, which is normally one banking day. While there is
no  charge to  shareholders  for this  service,  a fee will be  deducted  from a
shareholder's Fund account in case of insufficient  funds. This privilege may be
terminated at any time without charge or penalty by the  shareholder,  the Fund,
the Transfer Agent or Alger Inc. Class A share  purchases will remain subject to
the front-end load.
    

Automatic  Investment  Plan  

While  there  is no  charge  to  shareholders  for this  service,  a fee will be
deducted from a shareholder's Fund account in the case of insufficient  funds. A
shareholder's  Automatic  Investment  Plan may be terminated at any time without
charge or penalty by the shareholder, the Fund, the Transfer Agent or Alger Inc.
Class A share purchases will remain subject to the front-end load.

Automatic  Exchange Plan 

There is no charge to shareholders for this service.  A shareholder's  Automatic
Exchange  Plan may be  terminated  at any time without  charge or penalty by the
shareholder,  the  Fund,  the  Transfer  Agent  or  Alger  Inc.  The  Plan  will
automatically  be terminated if the automatic  exchange amount exceeds the Money
Market Portfolio  balance.  Shares held in certificate form are not eligible for
this service. Class A share purchases will remain subject to the front-end load.

REDEMPTIONS

The right of redemption of shares of a Portfolio may be suspended or the date of
payment  postponed for more than seven days (a) for any periods during which the
New York Stock Exchange (the "NYSE") is closed (other than for customary weekend
and holiday  closings),  (b) when trading in the markets the Portfolio  normally
utilizes is restricted, or an emergency, as defined by the rules and regulations
of  the  SEC,  exists,  making  disposal  of  the  Portfolio's   investments  or
determination of its net asset values not reasonably practicable or (c) for such
other  periods  as the SEC by order may  permit  for  protection  of the  Fund's
shareholders.  

Check  Redemption  Privilege  

Unless investors elect otherwise, checks drawn on jointly-owned accounts will be
honored with the signature of either of the joint owners. Shareholders should be

                                      -12-
<PAGE>

aware that use of the check redemption procedure does not give rise to a banking
relationship  between the  shareholder  and the  Transfer  Agent,  which will be
acting solely as transfer agent for the Portfolio;  nor does it create a banking
relationship  between the shareholder and the Fund. When a check is presented to
the Transfer Agent for payment,  the Transfer  agent,  as the investor's  agent,
will cause the Fund to redeem a sufficient  number of shares from the investor's
account to cover the amount of the check.  

An investor may expedite a redemption of shares by delivering  redemption checks
directly to Alger Shareholder Services, Inc., 30 Montgomery Street, Jersey City,
New Jersey, in which case a check issued by the Transfer Agent will be mailed or
made  available  on the next  business  day.  In order for an investor to have a
proceeds  check  mailed  or made  available  at the  Transfer  Agent,  a  letter
requesting the  redemption,  or a properly  executed stock power form,  with the
investor's signature guaranteed as described in the Prospectus must be delivered
to the Transfer Agent with the redemption check.

Shares for which  stock  certificates  have been  issued may not be  redeemed by
check.  An  investor's  account  with the Alger Money Market  Portfolio  will be
reduced by any contingent  deferred sales charge  applicable to any  redemption,
including a redemption by check. The check redemption  privilege may be modified
or terminated at any time by the Fund or by the Transfer Agent.

Redemptions in Kind

The  Prospectus  states  that  payment for shares  tendered  for  redemption  is
ordinarily  made  in  cash.  However,  if the  Board  of  Trustees  of the  Fund
determines  that it would be  detrimental  to the best interest of the remaining
shareholders  of the  Portfolio to make payment of a redemption  order wholly or
partly in cash,  the  Portfolio may pay the  redemption  proceeds in whole or in
part by a distribution  "in kind" of securities  from the Portfolio,  in lieu of
cash,  in  conformity  with  applicable  rules of the  Securities  and  Exchange
Commission.  The Fund has  elected to be  governed  by Rule 18f-1 under the Act,
pursuant to which a Portfolio is obligated to redeem shares solely in cash up to
the  lesser of  $250,000  or 1% of the net  assets of the  Portfolio  during any
90-day  period for any one  shareholder.  If shares are  redeemed  in kind,  the
redeeming  shareholder  might  incur  brokerage  or other  costs in selling  the
securities for cash. The method of valuing  securities used to make  redemptions
in kind will be the same as the  method  the Fund  uses to value  its  portfolio
securities and such  valuation will be made as of the time the redemption  price
is determined.

Certain Waivers of the Contingent Deferred 
Sales Charge

The  contingent   deferred  sales  change  ("CDSC")  which  may  be  imposed  on
redemptions  of Fund shares will be waived in certain  instances,  including (a)
redemptions of shares held at the time a shareholder  becomes  disabled or dies,
including the shares of a shareholder who owns the shares with his or her spouse
as joint tenants with right of  survivorship,  provided  that the  redemption is
requested  within  one  year  after  the  death  or  initial   determination  of
disability,  (b)  redemptions in connection  with the following  retirement plan
distributions: (i) lump-sum or other distributions from a qualified corporate or
Keogh retirement plan following retirement,  termination of employment, death or
disability  (or in the case of a five percent owner of the employer  maintaining
the plan, following  attainment of age 70l/2); (ii) required  distributions from
an  Individual  Retirement  Account  ("IRA") or custodial  account under Section
403(b)(7) of the  Internal  Revenue Code of 1986,  following  attainment  of age
70l/2; and (iii) a tax-free return of an excess  contribution to an IRA, and (c)
systematic  withdrawal  payments.  For  purposes of the waiver  described in (a)
above,  a person will be deemed  "disabled" if the person is unable to engage in
any  substantial  gainful  activity  by  reason  of any  medically  determinable
physical or mental  impairment  that can be expected to result in death or to be
of long-continued and indefinite duration.

Reinstatement Privilege

A  shareholder  who has redeemed  shares in the Fund may reinvest all or part of
the redemption  proceeds in the Fund without an initial sales charge and receive
a credit  for any  contingent  deferred  sales  charge  paid on the  redemption,
provided  the  reinvestment  is made within 30 days after the  redemption.  This
reinstatement   privilege  may  be  exercised   only  once  by  a   shareholder.
Reinstatement will not alter any capital gains tax payable on the redemption and
a loss may not be allowed for tax purposes.

Systematic Withdrawal Plan

A  systematic   withdrawal  plan  (the   "Withdrawal   Plan")  is  available  to
shareholders  who own shares of a Portfolio with a value  exceeding  $10,000 and
who wish to receive  specific  amounts of cash  periodically.  Withdrawals of at
least $50 monthly (but no more than one percent of the value of a  shareholder's
shares in the Portfolio)  may be made under the Withdrawal  Plan by redeeming as

                                      -13-
<PAGE>

many  shares  of the  Portfolio  as may be  necessary  to cover  the  stipulated
withdrawal   payment.   To  the  extent  that  withdrawals   exceed   dividends,
distributions  and appreciation of a shareholder's  investment in the Portfolio,
there  will be a  reduction  in the value of the  shareholder's  investment  and
continued  withdrawal  payments  may reduce  the  shareholder's  investment  and
ultimately  exhaust it.  Withdrawal  payments should not be considered as income
from investment in a Portfolio.

Shareholders  who wish to participate in the Withdrawal  Plan and who hold their
shares in  certificated  form  must  deposit  their  share  certificates  of the
Portfolio from which withdrawals will be made with Alger  Shareholder  Services,
Inc., as agent for Withdrawal Plan members.  All dividends and  distributions on
shares in the Withdrawal Plan are automatically reinvested at net asset value in
additional  shares  of  the  Portfolio  involved.   For  additional  information
regarding the Withdrawal Plan, contact the Fund.

EXCHANGES

In General

Class A shares may not be exchanged  for Class B shares.  Class B shares may not
be exchanged for Class A shares.

For  Shareholders  Maintaining  an Active  Account on October 17,  1992.  Shares
acquired in an exchange  are deemed to have been  purchased on the date on which
the shares given in exchange were purchased;  thus, an exchange would not affect
the running of the six-year  holding  period.  The initial sales charge and CDSC
would not apply to an  exchange  of shares of a class of one of the Alger  Small
Capitalization   Portfolio,   the  Alger  Midcap  Portfolio,  the  Alger  Growth
Portfolio,  the  Alger  Balanced  Portfolio  or the Alger  Capital  Appreciation
Portfolio (collectively,  the "Charge Portfolios") for shares of the Alger Money
Market  Portfolio,  but  redemptions  of shares of that  Portfolio  acquired  by
exchange of Class B shares from one or more of the Charge Portfolios are subject
to the charge on the same terms as the shares  given in  exchange.  If shares of
the Alger Money Market  Portfolio are exchanged for Class B shares of any of the
Charge Portfolios, any later redemptions of those shares would be subject to the
charge  based on the  period of time  since the shares  given in  exchange  were
purchased.

The following example illustrates the operation of the CDSC prior to October 17,
1992.  Assume  that on the first day of year 1 an investor  purchases  $1,000 of
shares  of each of the  Alger  Money  Market  Portfolio  and  the  Alger  Growth
Portfolio,  Class B. The  shareholder  may at any time  redeem the shares of the
Alger Money Market Portfolio without  imposition of the charge. If in year 3 the
shareholder  redeems  all the  Class B  shares  of the  Alger  Growth  Portfolio
purchased in year 1, a charge of three percent of the current net asset value of
those shares would be imposed on the redemption.  The  shareholder  could redeem
without imposition of the charge any of his or her shares of that Portfolio that
were purchased through reinvestment of dividends and capital gains distributions
as well as an amount of shares not exceeding any increase in the net asset value
of the $1,000 of shares originally purchased.  The shareholder could also at any
time  exchange  the  Class B shares of the Alger  Growth  Portfolio  for Class B
shares of any other Portfolio without  imposition of the charge. If those shares
were later  redeemed,  however,  the  redemption  would be subject to the charge
based on the  current net asset value of the shares and the period of time since
the original  purchase payment was made (with  adjustments for partial exchanges
and  redemptions  and any accretions in the  shareholder's  account by reason of
increases in net asset value and  reinvestment  of dividends  and capital  gains
distributions).  If the  foregoing  exchange  were made by the  shareholder  for
additional shares of the Alger Money Market Portfolio, any subsequent redemption
of shares of that  Portfolio  would be deemed to have been made  first  from the
$1,000 of shares of the Alger Money  Market  Portfolio  originally  purchased in
year 1, which are not subject to the charge,  and then from the shares  acquired
in the  exchange,  which are subject to the charge.  If instead the  shareholder
exchanged the shares of the Alger Money Market Portfolio originally purchased in
year 1 for  additional  Class B shares of the Alger Growth  Portfolio (or of the
other Charge  Portfolios) any later  redemption of those shares would be subject
to the charge in accordance with the foregoing rules based on the period of time
since the original  purchase  payment was made.  Thus, the period of time shares
were held in the Alger  Money  Market  Portfolio  would be  counted  toward  the
six-year holding period.  

For New  Shareholders  Opening an Account  after  October  17,  1992.  Effective
October 17,  1992,  new  shareholders  of the Fund are subject to the  following
terms and conditions  regarding the exchange of shares of the Fund's Portfolios.
Once an initial  sales  charge has been imposed on a purchase of Class A shares,
no additional charge is imposed in connection with their exchange.  For example,
a purchase of Alger Money Market  Portfolio  shares and  subsequent  exchange to

                                      -14-
<PAGE>

Class A shares  of a Charge  Portfolio  would  result  in the  imposition  of an
initial sales charge at the time of exchange.  If the initial  purchase had been
of Class A shares in a Charge  Portfolio,  an  exchange  to any other  Portfolio
would not result in an additional  initial sales charge.  No CDSC is assessed in
connection with exchanges at any time. In addition,  no charge is imposed on the
redemption  of  reinvested  dividends  or  capital  gains  distributions  or  on
increases  in the net  asset  value of  shares  of a  Portfolio  above  purchase
payments made with respect to that Portfolio during the six-year holding period.
A CDSC is assessed on redemptions of Class B shares of the Charge Portfolios and
of  shares of the Alger  Money  Market  Portfolio  that  have been  acquired  in
exchange for Class B shares of a Charge Portfolio, based solely on the period of
time the Class B shares are retained in the Charge  Portfolio.  Thus, the period
of time shares are held in the Alger Money Market  Portfolio will not be counted
towards the six-year holding period in the calculation of a CDSC.

The following examples  illustrate the operation of the CDSC for accounts opened
after October 17, 1992:  (1) An investor  purchases  Class B shares of the Alger
Growth  Portfolio  on the first day of year 1 and  exchanges  those  shares  for
shares of the Alger Money  Market  Portfolio in year 2. No charge is assessed at
the time of the exchange. If in year 4 the shareholder redeems all the shares, a
charge of four  percent of the current net asset value of those  shares would be
imposed on the  redemption  based on the period of time the shares were retained
in Class B of the Alger  Growth  Portfolio.  The time  period  during  which the
shares of the Alger Money Market  Portfolio  are held is not  included  when the
amount  of the  charge is  calculated.  The  shareholder  could  redeem  without
imposition  of  the  charge  any of  his  shares  that  were  purchased  through
reinvestment of dividends and capital gains  distributions  as well as an amount
of shares not  exceeding  any  increase in the net asset  value of the  original
purchase.  (2) An investor  purchases shares of the Alger Money Market Portfolio
on the first day of year 1 and exchanges  those shares for Class B shares of the
Alger Growth  Portfolio on the first day of year 2. No charge is assessed at the
time of the exchange.  If in year 4 the  shareholder  redeems all the shares,  a
charge of three  percent of the current net asset value of those shares would be
imposed on the  redemption  based on the period of time the shares were retained
in Class B of the Alger  Growth  Portfolio.  The time  period  during  which the
shares of the Alger Money Market  Portfolio  are held is not  included  when the
amount  of the  charge is  calculated.  The  shareholder  could  redeem  without
imposition  of  the  charge  any of  his  shares  that  were  purchased  through
reinvestment of dividends and capital gains  distributions  as well as an amount
of shares not  exceeding  any  increase in the net asset  value of the  original
purchase.

Conversion of Class B Shares

Record holders of "Qualified Class B Shares" (as defined below) will be entitled
to convert  those  shares to Class A Shares,  on the basis of the  relative  net
asset values per share of the two classes,  at any time prior to March 31, 1997.
For this purpose,  "Qualified  Class B Shares" shall mean Class B Shares held of
record by a  Processing  Organization  on behalf of (i)  investment  advisers or
financial  planners  trading  for their own  accounts  or the  accounts of their
clients and who charge a management, consulting or other fee for their services,
and clients of such investment  advisers or financial planners trading for their
own accounts if the accounts are linked to the master account of such investment
adviser or financial planner on the books and records of the record holder;  and
(ii)  retirement and deferred  compensation  plans and trusts used to fund those
plans.  The Fund has obtained an opinion of counsel that such  conversions  will
not  constitute  taxable  events under current  federal  income tax law, and the
conversion  right may be suspended if such an opinion is no longer  available at
the time of conversion.

Investment Manager

Alger Management serves as investment manager to each of the Portfolios pursuant
to separate  written  agreements (the "Management  Agreements").  Certain of the
services  provided by, and the fees paid by the Portfolios to, Alger  Management
under  the  Management  Agreements  are  described  in  the  Prospectus.   Alger
Management  pays the  salaries of all  officers  who are  employed by it . Alger
Management has agreed to maintain  office  facilities for the Fund,  furnish the
Fund with  statistical and research data,  clerical,  accounting and bookkeeping
services,  and certain other  services  required by the Fund, and to compute the
net  asset  values,  net  income  and  realized  capital  gains or losses of the
Portfolios.  Alger  Management  prepares  semi-annual  reports to the SEC and to
shareholders,  prepares  federal and state tax  returns  and filings  with state
securities commissions,  maintains the Fund's financial accounts and records and
generally  assists in all  aspects of the Fund's  operations.  Alger  Management
bears all expenses in connection  with the performance of its services under the
Management Agreements.

Each  Management  Agreement  provides that if, in any fiscal year, the aggregate
expenses of the Portfolio (exclusive of certain specified categories of expense)
exceed  the  expense  limitation  of any  state  having  jurisdiction  over  the
Portfolio, Alger Management will reimburse the Portfolio for that excess expense
to the extent required by state law. At the date of this Statement of Additional
Information, there is no state expense limitation applicable to any Portfolio.

During the fiscal years ended October 31, 1994, 1995, and 1996, Alger Management
earned under the terms of the  Management  Agreements  $711,113,  $830,000,  and
$1,214,904  respectively,  in  respect  of the  Alger  Money  Market  Portfolio;
$2,359,000,  $3,118,000,  and $4,478,467  respectively,  in respect of the Alger
Small Capitalization Portfolio; $444,000, $760,000, and $1,654,488 respectively,
in  respect  of the  Alger  Growth  Portfolio;  $26,000,  $27,000,  and  $82,116
respectively, in respect of the Alger Balanced Portfolio; $92,000, $244,000, and
$720,696  respectively,  in respect of the Alger MidCap  Growth  Portfolio;  and
$17,000,  $77,000,  and $861,617  respectively,  in respect of the Alger Capital
Appreciation Portfolio.  Some of these fees, however, were offset in whole or in
part by various expense  reimbursements and waivers. The expense  reimbursements
and  waivers for the fiscal year ended  October  31, 1996 are  described  in the
Notes  to  the  Financial  Statements  which  Financial  Statements  are  hereby
incorporated by reference.

Independent Public Accountants

Arthur Andersen LLP serves as independent public accountants for the Fund.

TAXES

The following is a summary of selected  federal income tax  considerations  that
may  affect  the Fund and its  shareholders.  The  summary  is not  intended  to
substitute  for  individual  tax advice and investors are urged to consult their
own tax  advisers  as to the  federal,  state  and  local  tax  consequences  of
investing in the Fund.

Each  Portfolio  intends to qualify as a "regulated  investment  company"  under
Subchapter M of the Internal  Revenue Code of 1986, as amended (the "Code").  If
qualified as a regulated  investment  company,  a Portfolio  will pay no federal
income taxes on its taxable net investment income (that is, taxable income other
than net realized  capital  gains) and its net realized  capital  gains that are
distributed to  shareholders.  To qualify under  Subchapter M, a Portfolio must,
among other  things:  (1)  distribute  to its  shareholders  at least 90% of its
taxable net investment  income and net realized  short-term  capital gains;  (2)
derive at least 90% of its gross income from dividends,  interest, payments with
respect  to loans of  securities,  gains from the sale or other  disposition  of
securities, or other income (including,  but not limited to, gains from options,
futures and forward contracts) derived with respect to the Portfolio's  business
of investing in securities;  (3) derive less than 30% of its annual gross income
from the sale or other  disposition of securities,  options,  futures or forward
contracts  held for less than three  months;  and (4)  diversify its holdings so

                                      -17-
<PAGE>

that, at the end of each fiscal quarter of the Portfolio (a) at least 50% of the
market value of the Portfolio's  assets is represented by cash, U.S.  Government
securities  and other  securities,  with those other  securities  limited,  with
respect  to any one  issuer,  to an amount no  greater  in value  than 5% of the
Portfolio's  total  assets  and to not more than 10% of the  outstanding  voting
securities  of the issuer,  and (b) not more than 25% of the market value of the
Portfolio's  assets is invested in the  securities of any one issuer (other than
U.S.  Government   securities  or  securities  of  other  regulated   investment
companies)  or of two or more issuers that the  Portfolio  controls and that are
determined to be in the same or similar  trades or businesses or related  trades
or businesses.  In meeting these requirements,  a Portfolio may be restricted in
the selling of  securities  held by the Portfolio for less than three months and
in the utilization of certain of the investment  techniques  described above and
in the Fund's prospectus.  As a regulated investment company,  each Portfolio is
subject  to  a  non-deductible   excise  tax  of  4%  with  respect  to  certain
undistributed  amounts of income and capital gains during the calendar year. The
Fund  expects  each  Portfolio to make  additional  distributions  or change the
timing of its distributions so as to avoid the application of this tax. Although
the Fund expects each Portfolio to make such  distributions  as are necessary to
avoid the  application of this tax,  certain of such  distributions,  if made in
January,  might be included in the taxable  income of  shareholders  in the year
ended in the previous December.

Payments  reflecting the dividend  income of the Portfolios will not qualify for
the  dividends-received  deduction for  corporations  if the Portfolio sells the
underlying stock before satisfying a 46-day holding period  requirement (91 days
for certain preferred stock). Dividends-received deductions will be allowed to a
corporate  shareholder only if similar holding period  requirements with respect
to shares of the Portfolio have been met.

In general,  any gain or loss on the redemption or exchange of Portfolio  shares
will be long-term  capital gain or loss if held by the shareholder for more than
one year,  and will be  short-term  capital gain or loss if held for one year or
less.  However,  if a shareholder  receives a distribution  taxable as long-term
capital  gain with  respect to Portfolio  shares,  and redeems or exchanges  the
shares before holding them for more than six months,  any loss on the redemption
or exchange up to the amount of the distribution  will be treated as a long-term
capital loss.

Dividends  of a  Portfolio's  net  investment  income and  distributions  of its
short-term  capital gains will be taxable as ordinary  income.  Distributions of
long-term  capital  gains  will be  taxable  as such  at the  appropriate  rate,
regardless of the length of time you have held shares of the  Portfolio.  If you
receive a  distribution  treated as long-term  capital gain with respect to Fund
shares,  and you redeem or exchange the shares before holding them for more than
six  months,  any loss on the  redemption  or  exchange  up to the amount of the
distribution  will be treated as long-term  capital loss.  Only  dividends  that
reflect  a  Portfolio's  income  from  certain  dividend-paying  stocks  will be
eligible   for  the   federal   dividends-received   deduction   for   corporate
shareholders.  None of the  dividends  paid by the Alger Money Market  Portfolio
will be eligible for the dividends-received deduction.

If a  Portfolio  is the holder of record of any stock on the record date for any
dividends payable with respect to such stock, such dividends are included in the
Portfolio's  gross  income  as of the later of (a) the date  such  stock  became
ex-dividend  with respect to such dividends  (i.e., the date on which a buyer of
the stock would not be entitled to receive the declared, but unpaid,  dividends)
or (b) the date the  Portfolio  acquired  such stock.  Accordingly,  in order to
satisfy its income distribution requirements, a Portfolio may be required to pay
dividends based on anticipated  earnings and shareholders may receive  dividends
in an earlier year than would otherwise be the case.

Investors  considering  buying shares of a Portfolio just prior to a record date
for a taxable  dividend  or  capital  gain  distribution  should be aware  that,
regardless of whether the price of the Portfolio shares to be purchased reflects
the amount of the forthcoming dividend or distribution payment, any such payment
will be a taxable dividend or distribution  payment.  

If a  shareholder  fails to furnish a correct  taxpayer  identification  number,
fails to fully report dividend or interest  income,  or fails to certify that he
or she has provided a correct taxpayer  identification number and that he or she
is not subject to such withholding,  then the shareholder may be subject to a 31
percent "backup  withholding tax" with respect to (i) any taxable  dividends and
distributions  and  (ii) any  proceeds  of any  redemption  of Fund  shares.  An
individual's  taxpayer  identification  number  is his or  her  social  security
number.  The 31 percent backup  withholding tax is not an additional tax and may
be credited against a shareholder's regular federal income tax liability.

ORGANIZATION

The Fund has been organized as an  unincorporated  business trust under the laws
of the Commonwealth of Massachusetts pursuant to an Agreement and Declaration of
Trust  dated  March 20, 1986 (the  "Trust  Agreement").  The Alger Money  Market
Portfolio,  Alger Small  Capitalization  Portfolio  and Alger  Growth  Portfolio
commenced  operations  on  November  11,  1986.  The  Alger  Balanced  Portfolio
commenced  operations  on  June 1,  1992,  the  Alger  MidCap  Growth  Portfolio
commenced  operations  on May  24,  1993  and  the  Alger  Capital  Appreciation
Portfolio commenced  operations on November 1, 1993. Prior to March 27, 1995 the
Alger Capital  Appreciation  Portfolio was known as the Alger  Leveraged  AllCap
Portfolio.  The word "Alger" in the Fund's name has been  adopted  pursuant to a
provision  contained  in the  Agreement  and  Declaration  of Trust.  Under that
provision,  Alger  Management  may terminate the Fund's  license to use the word
"Alger" in its name when Alger Management ceases to act as the Fund's investment
manager.  On December 31, 1996,  Class A shares were added to all  portfolios of
the Fund  except  the  Alger  Money  Market  Portfolio.  Class A  shares  have a
front-end load. The previously existing shares in those portfolios, subject to a
CDSC, were designated Class B shares on that date.

Shares of each Portfolio other than the Money Market  Portfolio are divided into
two classes, Class A and Class B. The classes differ in that: (a) each class has
a  different  class  designation;  (b) only the Class A Shares are  subject to a
front-end  sales charge  ("FESC");  (c) only the Class B Shares are subject to a
contingent  deferred sales charge  ("CDSC"),  except that certain Class A Shares
may also be  subject to a CDSC  different  from that to which the Class B Shares
are  subject;  (d) only the Class B Shares (as  described  below) are subject to
distribution fees under a plan adopted pursuant to Rule 12b-1 under the 1940 Act
(a "Rule 12b-1  Plan");  (e) to the extent that one class alone is affected by a
matter submitted to a vote of the shareholders,  then only that class has voting
power on the matter; (f) the exchange privileges of each class differ from those
of the other;  and (g) record holders of certain Class B Shares will be entitled
to convert those shares to Class A Shares at any time prior to March 31, 1997.

   
Shares do not have  cumulative  voting rights,  which means that holders of more
than 50 percent of the shares  voting for the election of Trustees can elect all
Trustees.  Shares  are  transferable  but  have  no  preemptive,  conversion  or
subscription  rights.  Shareholders  generally  vote by  Portfolio,  except with
respect to the election of Trustees  and the  ratification  of the  selection of
independent accountants, and by class within a Portfolio on matters in which the
interests  of one class  differ from those of another;  see also item (e) in the
preceding  paragraph.  In the interest of economy and convenience,  certificates
representing  shares of a Portfolio  are  physically  issued only upon  specific
written request of a shareholder.
    

Meetings of  shareholders  normally will not be held for the purpose of electing
Trustees  unless  and until such time as less than a  majority  of the  Trustees
holding  office have been  elected by  shareholders,  at which time the Trustees
then in office will call a  shareholders'  meeting for the election of Trustees.
Under  the  Act,  shareholders  of  record  of no less  than  two-thirds  of the
outstanding  shares of the Fund may remove a Trustee  through a  declaration  in
writing  or by vote  cast in person  or by proxy at a  meeting  called  for that
purpose. Under the Trust Agreement,  the Trustees are required to call a meeting
of shareholders for the purpose of voting on the question of removal of any such
Trustee when requested in writing to do so by the  shareholders of record of not
less than 10 percent of the Fund's outstanding shares.

Massachusetts law provides that shareholders could, under certain circumstances,
be held personally  liable for the obligations of the Fund.  However,  the Trust
Agreement  disclaims  shareholder  liability for acts or obligations of the Fund
and  requires  that  notice  of such  disclaimer  be  given  in each  agreement,
obligation or instrument entered into or executed by the Fund or a Trustee.  The
Trust Agreement  provides for  indemnification  from the Fund's property for all
losses  and  expenses  of  any  shareholder  held  personally   liable  for  the
obligations of the Fund. Thus, the risk of a shareholder's  incurring  financial
loss on account of shareholder  liability is limited to  circumstances  in which
the Fund itself would be unable to meet its obligations,  a possibility that the
Fund believes is remote. Upon payment of any liability incurred by the Fund, the
shareholder  paying the  liability  will be entitled to  reimbursement  from the
general assets of the Fund. The Trustees intend to conduct the operations of the
Fund in a manner so as to avoid, as far as possible,  ultimate  liability of the
shareholders for liabilities of the Fund.

DETERMINATION OF PERFORMANCE

Money Market Portfolio

The Alger Money Market  Portfolio's  "yield" and "effective  yield" described in
the Prospectus are calculated  according to formulas  prescribed by the SEC. The
Portfolio's  seven-day  "yield"  is  computed  by  determining  the net  change,
exclusive  of  capital  changes,  in the  value of a  hypothetical  pre-existing

                                      -20-
<PAGE>

account in the  Portfolio  having a balance of one share at the beginning of the
period,  dividing the net change in account value by the value of the account at
the  beginning  of the base  period to obtain the base period  return,  and then
multiplying the base period return by (365/7). The Portfolio's "effective yield"
is computed by compounding the  unannualized  base period return  (calculated as
above),  by adding one to it, raising the sum to a power equal to 365 divided by
seven,  and  subtracting  one  from the  result.  When the  Alger  Money  Market
Portfolio includes quotations of "yield" and "effective yield" that are based on
the income generated by an investment in the Portfolio over a thirty-day, or one
month, period, it will calculate the "yield" and "effective yield" in the manner
described above except that, in annualizing  the "yield" and "effective  yield,"
the formula will be adjusted to reflect the proper period.

For the seven-day period ended October 31, 1996, the annualized yield was 4.70%,
and the compounded effective yield was 4.81%.

Other Portfolios

The "total  return" and "yield"  described in the  Prospectus  as to each of the
Classes of the Portfolios, other than the Alger Money Market Portfolio, are also
computed according to formulas  prescribed by the SEC. These performance figures
are calculated in the following manner:

A.   Total  Return--A  Class'  average  annual  total  return  described  in the
     Prospectus is computed according to the following formula:

                                  P (1+T)n=ERV

Where:        P =   a hypothetical initial payment of $1,000
              T =   average annual total return
              n =   number of years

            ERV =   ending redeemable value of a hypothetical $1,000 payment 
                    made at the beginning of the 1, 5, or 10 year periods at the
                    end of the 1, 5 and 10 year periods (or fractional portion 
                    thereof);

The average annual total returns for the B Classes of the Portfolios, other than
the Money Market Portfolio, for the periods indicated below were as follows:

                                                                   Period

                    YIELD = 2[(----- + 1)6 - 1]
                                 cd

Where:         a =  dividends and interest earned during the period.

               b =  expenses accrued for the period (net of reimbursements).

               c = The average  daily  number of shares  outstanding  during the
                   period that were entitled to receive  dividends.  

               d = the maximum  offering price per share on the last day of the 
                   period.

In General

Current  performance  information  for  the  Classes  of the  Portfolios  may be
obtained by calling the Fund at the telephone  number provided on the cover page
of this  Statement of  Additional  Information.  Quoted  performance  may not be
indicative of future  performance.  The  performance of a class will depend upon
factors such as its expenses and the types and maturities of securities  held by
the Portfolio.

From time to time,  advertisements  or reports to  shareholders  may compare the
yield or performance of a Portfolio to that of other mutual funds with a similar
investment  objective.  The yield of the Alger Money Market  Portfolio  might be
compared  with,  for example,  averages  compiled by  IBC/Donoghue's  Money Fund
Report,  a  widely  recognized,   independent   publication  that  monitors  the
performance  of money market mutual  funds.  The yield of the Alger Money Market
Portfolio  might also be compared  with the average  yield  reported by the Bank
Rate Monitor for money market deposit  accounts  offered by the 50 leading banks
and thrift institutions in the top five standard metropolitan areas.  Similarly,
the  performance  of the other  Portfolios,  for  example,  might be compared to
rankings  prepared  by  Lipper  Analytical  Services  Inc.,  which  is a  widely
recognized,  independent  service that monitors the performance of mutual funds,
as well as to various unmanaged  indices,  such as the S&P 500, the Russell 2000
Growth   Index,   the  Wilshire   Small  Company   Growth   Index,   the  Lehman
Government/Corporate  Bond  Index or the S&P  MidCap  400  Index.  In  addition,
evaluations  of  the  Portfolios  published  by  nationally  recognized  ranking
services  or  articles  regarding  performance,  rankings  and  other  Portfolio
characteristics may appear in national publications  including,  but not limited
to, Barron's, Business Week, Forbes, Institutional Investor, Investor's Business
Daily, Kiplinger's Personal Finance, Money, Morningstar, The New York Times, USA
Today and The Wall  Street  Journal and may be  included  in  advertisements  or
communications to shareholders.  Any given performance  comparison should not be
considered as  representative  of such  Portfolio's  performance  for any future
period.

APPENDIX

      Description of the highest commercial paper, bond and other short and long
term  rating  categories  assigned  by  Standard & Poor's  Corporation  ("S&P"),
Moody's Investors Service,  Inc.  ("Moody's"),  "Fitch" Investors Service,  Inc.
("Fitch") and Duff and Phelps, Inc. ("Duff").

Commercial Paper and Short-Term Ratings

      The  designation  A-l by S&P indicates  that the degree of safety  reading
timely payment is either overwhelming or very strong. Those issues determined to
possess  overwhelming  safety  characteristics  are denoted with a plus sign (+)
designation.  Capacity for timely  payment on issues with an A-2  designation is
strong.  However,  the  relative  degree of safety is not as high as for  issues
designated A-l.

      The rating Prime-l (P-l) is the highest  commercial  paper rating assigned
by Moody's.  Issuers of P-l paper must have a superior capacity for repayment of
short term  promissory  obligations  and ordinarily will be evidenced by leading
market positions in well established  industries,  high rates of return of funds
employed,  conservative capitalization structures with moderate reliance on debt
and  ample  asset  protection,  broad  margins  in  earnings  coverage  of fixed
financial charges and high internal cash generation, and well established access
to a range of  financial  markets and assured  sources of  alternate  liquidity.
Issues rated  Prime-2  (P-2) have a strong  capacity for repayment of short-term
promissory  obligations.  This  ordinarily  will  be  evidenced  by  many of the
characteristics  cited above but to a lesser degree Earnings trends and coverage
ratios,  while  sound,  will  be  more  subject  to  variation.   Capitalization
characteristics,  while  still  appropriate,  may be more  affected  by external
conditions. Ample alternate liquidity is maintained.

      The rating Fitch-l (Highest Grade) is the highest  commercial paper rating
assigned  by Fitch.  Paper rated  Fitch-l is  regarded  as having the  strongest
degree of assurance for timely payment.  The rating Fitch-2 (Very Good Grade) is
the second highest  commercial  paper rating assigned by Fitch which reflects an
assurance of timely  payment  only  slightly  less in degree than the  strongest
issues.

      The rating Duff-l is the highest commercial paper rating assigned by Duff.
Paper rated Duff-l is regarded as having very high  certainty of timely  payment
with excellent  liquidity factors which are supported by ample asset protection.
Risk factors are minor.  Paper rated Duff-2 is regarded as having good certainty
of timely payment,  good access to capital  markets and sound liquidity  factors
and company fundamentals. Risk factors are small.

Bond and Long-Term Ratings

      Bonds rated AA by S&P are judged by S&P to be high-grade  obligations  and
in the majority of  instances  differ only in small degree from issues rated AAA
(S&P's highest rating).  Bonds rated AAA are considered by S&P to be the highest
grade  obligations and possess the ultimate degree of protection as to principal
and interest.  With AA bonds, as with AAA bonds,  prices move with the long-term
money market.  Bonds rated A by S&P have a strong  capacity to pay principal and
interest,  although they are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions.

      S&P's BBB rated bonds,  or  medium-grade  category  bonds,  are borderline
between  definitely sound  obligations and those where the speculative  elements
begin to predominate.  These bonds have adequate asset coverage and normally are
protected by satisfactory earnings. Their susceptibility to changing conditions,
particularly  to  depressions,   necessitates  constant  watching.  These  bonds
generally are more responsive to business and trade  conditions than to interest
rates. This group is the lowest that qualifies for commercial bank investment.

      Bonds  rated  Aa by  Moody's  are  judged  to be of  high  quality  by all
standards.  Together with bonds rated Aaa (Moody's highest rating) they comprise
what are generally known as high-grade  bonds. Aa bonds are rated lower than Aaa
bonds because  margins of protection  may not be as large as those of Aaa bonds,
or fluctuation of protective elements may be of greater amplitude,  or there may
be other elements  present that make the long-term  risks appear somewhat larger
than  those  applicable  to Aaa  securities.  Bonds  that are rated A by Moody's

                                      A-1
<PAGE>

APPENDIX
(continued)

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 that suggest a susceptibility
to impairment in the future.

      Moody's Baa rated bonds 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.

      Moody's applies the numerical  modifiers 1, 2 and 3 to each generic rating
classification  from Aa through B. 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.

      Bonds  rated AAA by Fitch are judged by Fitch to be  strictly  high grade,
broadly   marketable,   suitable  for   investment  by  trustees  and  fiduciary
institutions  and liable to but slight  market  fluctuation  other than  through
changes  in the money  rate.  The prime  feature  of an AAA bond is a showing of
earnings several times or many times interest requirements,  with such stability
of  applicable  earnings  that  safety is beyond  reasonable  question  whatever
changes occur in  conditions.  Bonds rated AA by Fitch are judged by Fitch to be
of safety virtually  beyond question and are readily  salable,  whose merits are
not unlike those of the AAA class, but whose margin of safety is less strikingly
broad. The issue may be the obligation of a small company,  strongly secured but
influenced as to rating by the lesser financial power of the enterprise and more
local type of market.

      Bonds rated Duff-l are judged by Duff to be of the highest  credit quality
with negligible risk factors;  only slightly more than U.S. Treasury debt. Bonds
rated  Duff-2,  3 and 4 are  judged by Duff to be of high  credit  quality  with
strong  protection  factors.  Risk is modest but may vary  slightly from time to
time because of economic conditions.
