RISK/RETURN SUMMARY: INVESTMENTS,
RISKS & PERFORMANCE

INVESTMENTS: THE ALGER AMERICAN FUND

The  investment  goal  and  primary  approach  of each  portfolio  is  discussed
individually  below. All of the portfolios (other than the fixed-income  portion
of the Balanced Portfolio) invest primarily in equity securities, such as common
or   preferred   stocks,   which  are  listed  on  U.S.   exchanges  or  in  the
over-the-counter  market.  They invest primarily in "growth" stocks.  The Fund's
Manager, Fred Alger Management, Inc., believes that these companies tend to fall
into one of two categories:

o  High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o  Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

The company's market  capitalization  will dictate in which portfolio(s) it will
be  placed.  The  market  capitalization  of a  company  is its  price per share
multiplied by its number of outstanding shares.


ALGER AMERICAN SMALL CAPITALIZATION PORTFOLIO

GOAL

THE ALGER  AMERICAN  SMALL  CAPITALIZATION  PORTFOLIO  SEEKS  LONG-TERM  CAPITAL
APPRECIATION.


APPROACH

It focuses on small,  fast-growing  companies  that offer  innovative  products,
services  or  technologies  to a rapidly  expanding  marketplace.  Under  normal
circumstances, the portfolio invests primarily in the equity securities of small
capitalization  companies.  A small  capitalization  company  is one  that has a
market  capitalization  within the range of the Russell(R)  2000 Growth Index or
the S&P(R) SmallCap 600 Index.


ALGER AMERICAN MIDCAP GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN MIDCAP GROWTH PORTFOLIO SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on midsize  companies with promising growth  potential.  Under normal
circumstances,  the  portfolio  invests  primarily in the equity  securities  of
companies  having a market  capitalization  within the range of companies in the
S&P(R) MidCap 400 Index.


ALGER AMERICAN GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN GROWTH PORTFOLIO SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on  companies  that  generally  have broad  product  lines,  markets,
financial  resources and depth of management.  Under normal  circumstances,  the
portfolio  invests  primarily in the equity  securities of large companies.  The
portfolio  considers  a large  company  to have a  market  capitalization  of $1
billion or greater.

<PAGE>

ALGER AMERICAN BALANCED PORTFOLIO

GOAL

THE ALGER AMERICAN BALANCED PORTFOLIO SEEKS CURRENT INCOME AND LONG-TERM CAPITAL
APPRECIATION.


APPROACH

It  focuses  on stocks of  companies  with  growth  potential  and  fixed-income
securities,  with emphasis on  income-producing  securities which appear to have
some  potential  for  capital  appreciation.  Under  normal  circumstances,  the
portfolio  invests in common stocks and fixed-income  securities,  which include
commercial  paper and bonds rated within the 4 highest  rating  categories by an
established  rating  agency.  Ordinarily,  at least 25% of the  portfolio's  net
assets are invested in fixed-income securities.


ALGER AMERICAN LEVERAGED ALLCAP PORTFOLIO

GOAL

THE  ALGER  AMERICAN   LEVERAGED  ALLCAP   PORTFOLIO  SEEKS  LONG-TERM   CAPITAL
APPRECIATION.


APPROACH

Under normal  circumstances,  the portfolio  invests in the equity securities of
companies of any size which demonstrate promising growth potential.

The portfolio can leverage, that is, borrow money, to buy additional securities.
By borrowing  money,  the portfolio has the potential to increase its returns if
the  increase  in the  value of the  securities  purchased  exceeds  the cost of
borrowing, including interest paid for the money borrowed.


ALGER AMERICAN INCOME & GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN INCOME & GROWTH  PORTFOLIO  PRIMARILY SEEKS TO PROVIDE A HIGH
LEVEL OF DIVIDEND INCOME; ITS SECONDARY GOAL IS TO PROVIDE CAPITAL APPRECIATION.


APPROACH

The portfolio  invests in dividend paying equity  securities,  such as common or
preferred  stocks,  preferably  those  which the  Manager  believes  also  offer
opportunities for capital appreciation.

PRINCIPAL RISKS


RISKS APPLICABLE TO ALL EQUITY PORTFOLIOS

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your  investment is a risk of  investing.  A portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also,  a Fund  investment  may not  grow  as  fast as the  rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the equity portfolios' investment styles and objectives,  an investment
in them may be better suited to investors who seek long-term  capital growth and
can tolerate fluctuations in their investment's value.

A portfolio's trading in some stocks may be relatively  short-term,  meaning the
Fund may buy a  security  and sell it a short time  later to take  advantage  of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase a portfolio's realized gains, thereby increasing

                                                                               3

the amount of taxable distributions to shareholders at the end of the year.

There may be additional risks applicable to a specific  portfolio because of its
investment approach.


RISKS APPLICABLE TO ALGER AMERICAN
SMALL CAPITALIZATION PORTFOLIO

A risk of investing in the portfolio is:

o the  possibility  of greater  risk by  investing  in  smaller,  less  seasoned
  companies rather than larger, more established companies owing to such factors
  as inexperienced management and limited financial resources


RISKS APPLICABLE TO ALGER AMERICAN
MIDCAP GROWTH PORTFOLIO

A risk of investing in the portfolio is:

o the possibility of greater risk by investing in medium-sized  companies rather
  than larger, more established companies


RISKS APPLICABLE TO ALGER AMERICAN GROWTH PORTFOLIO

The portfolio's primary risks are those summarized above in "Risks Applicable to
All Equity Portfolios."


RISKS APPLICABLE TO ALGER AMERICAN
BALANCED PORTFOLIO

The primary risks arising from the fixed-income portion of the portfolio are:

o fixed income securities' sensitivity to interest rate movements

o the potential for a decline in the portfolio's market value in the event of an
  issuer's falling credit rating or actual default

The primary risks for the equity  portion of the portfolio are those  summarized
above in "Risks Applicable to All Equity Portfolios."


RISKS APPLICABLE TO ALGER AMERICAN
LEVERAGED ALLCAP PORTFOLIO

A risk of investing in the portfolio is:

o the risk that the cost of borrowing  money to leverage will exceed the returns
  for the securities  purchased or that the securities purchased may actually go
  down in value; thus, the portfolio's net asset value can decrease more quickly
  than if the portfolio had not borrowed


RISKS APPLICABLE TO ALGER AMERICAN
INCOME & GROWTH PORTFOLIO

A risk of investing in the portfolio is:

o the  possibility  that  companies may cut or fail to declare  dividends due to
  market downturns or other reasons

PERFORMANCE

The following bar charts show the changes in each  portfolio's  performance from
year to year and give you some indication of the risks of investing in the Fund.
They assume reinvestment of dividends and distributions.

The Average  Annual Total Return tables compare a portfolio's  performance  over
several periods with that of an appropriate  benchmark index. The annual returns
assume  reinvestment  of  dividends  and  distributions.  Remember  that  how  a
portfolio has performed in the past is not  necessarily  an indication of how it
will perform in the future.

Each index used in the tables is a broad index  designed  to track a  particular
market or market  segment.  No expenses or fees are reflected in the returns for
the  indexes,   which  are  unmanaged.   All  returns  for  the  indexes  assume
reinvestment of dividends and interest of the underlying securities that make up
the respective index.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the  Fund's  operating  expenses  remain  the same as in the table
above.  The figures  shown would be the same whether or not you sold your shares
at the end of each  period.  Although  your actual costs may be higher or lower,
based on these assumptions your costs would be:

ADDITIONAL INFORMATION ABOUT
THE FUND'S INVESTMENTS

Each portfolio may invest up to 100% of its assets in cash, high-grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets  from a  temporary  unacceptable  risk of loss,  rather than
directly to promote the portfolio's investment objective.

Other  securities  the  portfolios  may  invest in are  discussed  in the Fund's
Statement of Additional Information (see back cover).

MANAGEMENT AND ORGANIZATION

MANAGER

Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same manager since inception,  and
the  portfolios pay the Manager fees at these annual rates based on a percentage
of  average  daily  net  assets:   Small  Capitalization  and  Leveraged  AllCap
Portfolios  --  .85%;  MidCap  Growth   Portfolio--.80%;   Growth  and  Balanced
Portfolios-- .75%; Income & Growth Portfolio-- .625%.

PORTFOLIO MANAGERS
David  Alger,  Seilai  Khoo,  Ron Tartaro and Steven  Thumm are the  individuals
responsible  for the day-to-day  management of the portfolios  investments.  Mr.
Alger,  a manager  of all of the  portfolios  since  their  inception,  has been
employed by the Manager as  Executive  Vice  President  and Director of Research
since 1971,  and as President  since 1995.  Ms. Khoo, a co-manager  of the Small
Capitalization  and  Leveraged  AllCap  Portfolios,  has been  employed by Alger
Management  since 1989, as a senior research  analyst until 1995 and as a Senior
Vice President and co-manager since 1995. Mr. Tartaro, a co-manger of the MidCap
Growth,  Growth,  Income & Growth and Balanced Portfolios,  has been employed by
Alger  Management  since 1990, as a senior research  analyst until 1995 and as a
Senior  Vice  President  and  co-manager  since  1995.  Steven  Thumm  serves as
co-manager of the Balanced  Portfolio.  He has been employed by the Manager as a
fixed income analyst since 1991.

YEAR 2000
The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other Year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

SHAREHOLDER INFORMATION

DISTRIBUTOR

Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302


TRANSFER AGENT

Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolios is calculated as of the close of business (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of each  portfolio on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolios are valued on the basis of amortized cost.

The Fund  declares  and  pays  dividends  and  distributions  by the  portfolios
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distributions from these investment vehicles are taxable as ordinary
income at the rate applicable to each  participant at the time of  distribution.
In certain cases, distributions made to a participant prior to the participant's
reaching  age  59-1/2  are  subject to a penalty  tax  equivalent  to 10% of the
distributed  amount,  in  addition  to the  ordinary  income tax payable on such
amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.


          NAV  (NET  ASSET  VALUE) IS   COMPUTED  BY   ADDING
         TOGETHER  THE  VALUE  OF  THE PORTFOLIO'S INVESTMENTS
        PLUS CASH AND OTHER ASSETS, SUBTRACTING ITS LIABILITIES
       AND  THEN  DIVIDING  THE  RESULT  BY  THE  NUMBER  OF ITS
                                             OUTSTANDING SHARES.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in a portfolio  directly,  but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.


                                                                               9

FINANCIAL HIGHLIGHTS

The  financial  highlights  table  is  intended  to  help  you  understand  each
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).  The financial  highlights for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are
included in the Annual Report, which is available upon request.

RISK/RETURN SUMMARY:
INVESTMENTS, RISKS & PERFORMANCE

INVESTMENTS: THE ALGER AMERICAN FUND

The  investment  goal  and  primary  approach  of each  portfolio  is  discussed
individually  below. All of the portfolios (other than the fixed-income  portion
of the Income & Growth Portfolio) invest primarily in equity securities, such as
common or  preferred  stocks,  which  are  listed  on U.S.  exchanges  or in the
over-the-counter  market.  They invest primarily in "growth" stocks.  The Fund's
Manager, Fred Alger Management, Inc., believes that these companies tend to fall
into one of two categories:

o  High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o  Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

The company's market  capitalization  will dictate in which portfolio(s) it will
be  placed.  The  market  capitalization  of a  company  is its  price per share
multiplied by its number of outstanding shares.


ALGER AMERICAN SMALL CAPITALIZATION PORTFOLIO

GOAL

THE ALGER  AMERICAN  SMALL  CAPITALIZATION  PORTFOLIO  SEEKS  LONG-TERM  CAPITAL
APPRECIATION.


APPROACH

It focuses on small,  fast-growing  companies  that offer  innovative  products,
services  or  technologies  to a rapidly  expanding  marketplace.  Under  normal
circumstances, the portfolio invests primarily in the equity securities of small
capitalization  companies.  A small  capitalization  company  is one  that has a
market  capitalization  within the range of the Russell(R)  2000 Growth Index or
the S&P(R) SmallCap 600 Index


ALGER AMERICAN MIDCAP GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN MIDCAP GROWTH PORTFOLIO
SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on midsize  companies with promising growth  potential.  Under normal
circumstances,  the  portfolio  invests  primarily in the equity  securities  of
companies  having a market  capitalization  within the range of companies in the
S&P(R) MidCap 400 Index.


ALGER AMERICAN GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN GROWTH PORTFOLIO 
SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on  companies  that  generally  have broad  product  lines,  markets,
financial  resources and depth of management.  Under normal  circumstances,  the
portfolio  invests  primarily in the equity  securities of large companies.  The
portfolio  considers  a large  company  to have a  market  capitalization  of $1
billion or greater.

ALGER AMERICAN LEVERAGED ALLCAP PORTFOLIO

GOAL

THE ALGER AMERICAN LEVERAGED ALLCAP PORTFOLIO
SEEKS LONG-TERM CAPITAL APPRECIATION.

APPROACH

Under normal  circumstances,  the portfolio  invests in the equity securities of
companies of any size which demonstrate promising growth potential.

The portfolio can leverage, that is, borrow money, to buy additional securities.
By borrowing  money,  the portfolio has the potential to increase its returns if
the  increase  in the  value of the  securities  purchased  exceeds  the cost of
borrowing, including interest paid for the money borrowed.

ALGER AMERICAN INCOME &GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN  INCOME &GROWTH  PORTFOLIO  PRIMARILY SEEKS TO PROVIDE A HIGH
LEVEL OF DIVIDEND INCOME; ITS SECONDARY GOAL IS TO PROVIDE CAPITAL APPRECIATION.


APPROACH

The portfolio  invests in dividend paying equity  securities,  such as common or
preferred  stocks,  preferably  those  which the  Manager  believes  also  offer
opportunities for capital appreciation.

PRINCIPAL RISKS


RISKS APPLICABLE TO ALL PORTFOLIOS

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your  investment is a risk of  investing.  A portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also,  a Fund  investment  may not  grow  as  fast as the  rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolios' investment styles and objectives, an investment in them
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

A portfolio's trading in some stocks may be relatively  short-term,  meaning the
Fund may buy a  security  and sell it a short time  later to take  advantage  of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase a portfolio's  realized  gains,  thereby  increasing  the amount of
taxable distributions to shareholders at the end of the year.

There may be additional risks applicable to a specific  portfolio because of its
investment approach.

                                                                               3

<PAGE>

RISKS APPLICABLE TO ALGER AMERICAN
SMALL CAPITALIZATION PORTFOLIO

A risk of investing in the portfolio is:

o the possibility of greater risk by investing in developmental  stage companies
  rather than larger, more established companies


RISKS APPLICABLE TO ALGER AMERICAN
MIDCAP GROWTH PORTFOLIO

A risk of investing in the portfolio is:

o the possibility of greater risk by investing in medium-sized  companies rather
  than larger, more established companies owing to such factors as inexperienced
  management and limited financial resources


RISKS APPLICABLE TO ALGER AMERICAN GROWTH PORTFOLIO

The portfolio's primary risks are those summarized above in "Risks Applicable to
All Portfolios."


RISKS APPLICABLE TO ALGER AMERICAN
LEVERAGED ALLCAP PORTFOLIO

A risk of investing in the portfolio is:

o the risk that the cost of borrowing  money to leverage will exceed the returns
  for the securities  purchased or that the securities purchased may actually go
  down in value; thus, the portfolio's net asset value can decrease more quickly
  than if the portfolio had not borrowed


RISKS APPLICABLE TO ALGER AMERICAN
INCOME &GROWTH PORTFOLIO

A risk of investing in the portfolio is:

o the  possibility  that  companies may cut or fail to declare  dividends due to
  market downturns or other reasons

PERFORMANCE

The following bar charts show the changes in the  portfolio's  performance  from
year to year and give you some indication of the risks of investing in the Fund.
They assume reinvestment of dividends and distributions. 

The Average  Annual Total Return tables compare a portfolio's  performance  over
several  periods  with  that of an  appropriate  benchmark  index.  They  assume
reinvestment of dividends and  distributions.  Remember that how a portfolio has
performed in the past is not necessarily an indication of how it will perform in
the future.

Each index used in the tables is a broad index  designed  to track a  particular
market or market  segment.  No expenses or fees are reflected in the returns for
the  indexes,   which  are  unmanaged.   All  returns  for  the  indexes  assume
reinvestment of dividends and interest of the underlying securities that make up
the respective index.

o S&P 500  IndexR: An index of large  company  common  stocks  considered  to be
  representative of the U.S. stock market in general.

o Russell  2000  Growth  IndexR: An index of  common  stocks  designed  to track
  performance of small capitalization companies.

o S&P Midcap 400 IndexR: An index of common stocks designed to track performance
  of medium capitalization companies.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the  Fund's  operating  expenses  remain  the same as in the table
above.  The figures  shown would be the same whether or not you sold your shares
at the end of each  period.  Although  your actual costs may be higher or lower,
based on these assumptions your costs would be:

ADDITIONAL INFORMATION ABOUT THE
FUND'S INVESTMENTS

Each portfolio may invest up to 100% of its assets in cash, high-grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets  from a  temporary  unacceptable  risk of loss,  rather than
directly to promote the portfolio's investment objective.

Other  securities  the  portfolios  may  invest in are  discussed  in the Fund's
Statement of Additional Information (see back cover).

1 World Trade Center
Suite 9333
New York, NY 10048

billion in other assets. The Fund has had the same manager since inception,  and
the  portfolios pay the Manager fees at these annual rates based on a percentage
of  average  daily  net  assets:   Small  Capitalization  and  Leveraged  AllCap
Portfolios -- .85%;  MidCap Growth  Portfolio--.80%;  Growth  Portfolio--  .75%;
Income & Growth Portfolio-- .625%.

                                                                               7

PORTFOLIO MANAGERS

David  Alger,  Seilai  Khoo,  Ron Tartaro and Steven  Thumm are the  individuals
responsible for the day-to-day  management of the portfolios'  investments.  Mr.
Alger,  a manager  of all of the  portfolios  since  their  inception,  has been
employed by the Manager as  Executive  Vice  President  and Director of Research
since 1971,  and as President  since 1995.  Ms. Khoo, a co-manager  of the Small
Capitalization  and  Leveraged  AllCap  Portfolios,  has been  employed by Alger
Management  since 1989, as a senior research  analyst until 1995 and as a Senior
Vice President and comanager since 1995. Mr. Tartaro,  a comanager of the MidCap
Growth and Growth Portfolios,  has been employed by Alger Management since 1990,
as a senior  research  analyst  until 1995 and as a Senior  Vice  President  and
comanager  since  1995.  Steven  Thumm  serves  as  comanager  of  the  Balanced
Portfolio.  He has been employed by the Manager as a fixed income  analyst since
1991 and comanager since 1995.

YEAR 2000

The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other Year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

SHAREHOLDER INFORMATION

DISTRIBUTOR

Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302

TRANSFER AGENT

Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolios is calculated as of the close of business (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of each  portfolio on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolios are valued on the basis of amortized cost.

The Fund  declares  and  pays  dividends  and  distributions  by the  portfolios
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment income and net realized

<PAGE>

capital gains until they receive a distribution of the dividends from their plan
accounts. Generally, distributions from these investment vehicles are taxable as
ordinary  income  at the  rate  applicable  to each  participant  at the time of
distribution. In certain cases, distributions made to a participant prior to the
participant's reaching age 59-1/2 are subject to a penalty tax equivalent to 10%
of the  distributed  amount,  in addition to the ordinary  income tax payable on
such amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.



          NAV  (NET  ASSET  VALUE) IS   COMPUTED  BY   ADDING
         TOGETHER  THE  VALUE  OF  THE PORTFOLIO'S INVESTMENTS
        PLUS CASH AND OTHER ASSETS, SUBTRACTING ITS LIABILITIES
       AND  THEN  DIVIDING  THE  RESULT  BY  THE  NUMBER  OF ITS
                                             OUTSTANDING SHARES.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in a portfolio  directly,  but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.

                                                                               9

FINANCIAL HIGHLIGHTS

The  financial  highlights  table  is  intended  to  help  you  understand  each
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).  The financial  highlights for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are
included in the Annual Report, which is available upon request.

RISK/RETURN SUMMARY:
INVESTMENTS, RISKS & PERFORMANCE


INVESTMENTS: THE ALGER AMERICAN FUND

The  investment  goal  and  primary  approach  of each  portfolio  is  discussed
individually below. All of the portfolios invest primarily in equity securities,
such as common or preferred stocks, which are listed on U.S. exchanges or in the
over-the-counter  market.  They invest primarily in "growth" stocks.  The Fund's
Manager, Fred Alger Management, Inc., believes that these companies tend to fall
into one of two categories:

o High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o  Positive Life Cycle Change


   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

The company's market  capitalization  will dictate in which portfolio(s) it will
be placed  in.  The  market  capitalization  of a company is its price per share
multiplied by its number of outstanding shares.


ALGER AMERICAN SMALL CAPITALIZATION PORTFOLIO

GOAL

THE ALGER  AMERICAN  SMALL  CAPITALIZATION  PORTFOLIO  SEEKS  LONG-TERM  CAPITAL
APPRECIATION.


APPROACH

It focuses on small,  fast-growing  companies  that offer  innovative  products,
services  or  technologies  to a rapidly  expanding  marketplace.  Under  normal
circumstances, the portfolio invests primarily in the equity securities of small
capitalization  companies.  A small  capitalization  company  is one  that has a
market  capitalization  within the range of the Russell(R)  2000 Growth Index or
the S&P(R) SmallCap 600 Index.


ALGER AMERICAN MIDCAP GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN MIDCAP GROWTH PORTFOLIO
SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on midsize  companies with promising growth  potential.  Under normal
circumstances,  the  portfolio  invests  primarily in the equity  securities  of
companies  having a market  capitalization  within the range of companies in the
S&P(R) MidCap 400 Index.

<PAGE>

ALGER AMERICAN GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN GROWTH PORTFOLIO SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on  companies  that  generally  have broad  product  lines,  markets,
financial  resources and depth of management.  Under normal  circumstances,  the
portfolio  invests  primarily in the equity  securities of large companies.  The
portfolio  considers  a large  company  to have a  market  capitalization  of $1
billion or greater.


ALGER AMERICAN LEVERAGED ALLCAP PORTFOLIO

GOAL

THE  ALGER  AMERICAN   LEVERAGED  ALLCAP   PORTFOLIO  SEEKS  LONG-TERM   CAPITAL
APPRECIATION.

APPROACH

Under normal  circumstances,  the portfolio  invests in the equity securities of
companies of any size which demonstrate promising growth potential.

The portfolio can leverage, that is, borrow money, to buy additional securities.
By borrowing  money,  the portfolio has the potential to increase its returns if
the  increase  in the  value of the  securities  purchased  exceeds  the cost of
borrowing, including interest paid for the money borrowed.


[GRAPHIC OMITTED]

PRINCIPAL RISKS


RISKS APPLICABLE TO ALL PORTFOLIOS

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your  investment is a risk of  investing.  A portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also,  a Fund  investment  may not  grow  as  fast as the  rate of
inflation  and stock tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolios' investment styles and objectives, an investment in them
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

A portfolio's trading in some stocks may be relatively  short-term,  meaning the
Fund may buy a  security  and sell it a short time  later to take  advantage  of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase a portfolio's  realized  gains,  thereby  increasing  the amount of
taxable distributions to shareholders at the end of the year.


                                                                               3
<PAGE>

There may be additional risks applicable to a specific  portfolio because of its
investment approach.


RISKS APPLICABLE TO ALGER AMERICAN
SMALL CAPITALIZATION PORTFOLIO

A risk of investing in the portfolio is:

o the  possibility  of greater  risk by  investing  in  smaller,  less  seasoned
  companies rather than larger, more established companies owing to such factors
  as inexperienced management and limited financial resources

RISKS APPLICABLE TO ALGER AMERICAN
MIDCAP GROWTH PORTFOLIO

A risk of investing in the portfolio is:

o the possibility of greater risk by investing in medium-sized  companies rather
  than larger, more established companies

RISKS APPLICABLE TO ALGER AMERICAN GROWTH PORTFOLIO

The portfolio's primary risks are those summarized above in "Risks Applicable to
All Portfolios".


RISKS APPLICABLE TO ALGER AMERICAN
LEVERAGED ALLCAP PORTFOLIO

A risk of investing in the portfolio is:

o the risk that the cost of borrowing  money to leverage will exceed the returns
  for the securities  purchased or that the securities purchased may actually go
  down in value; thus, the portfolio's net asset value can decrease more quickly
  than if the portfolio had not borrowed

PERFORMANCE

The following bar charts show the changes in the  portfolio's  performance  from
year to year and give you some indication of the risks of investing in the Fund.
They assume reinvestment of dividends and distributions.

The Average  Annual Total Return tables compare a portfolio's  performance  over
several  periods  with  that of an  appropriate  benchmark  index.  They  assume
reinvestment of dividends and  distributions.  Remember that how a portfolio has
performed in the past is not necessarily an indication of how it will perform in
the future.

Each index used in the tables is a broad index  designed  to track a  particular
market or market  segment.  No expenses or fees are reflected in the returns for
the  indexes,   which  are  unmanaged.   All  returns  for  the  indexes  assume
reinvestment of dividends and interest of the underlying securities that make up
the respective index.

o S&P 500  IndexR: An index of large  company  common  stocks  considered  to be
  representative of the U.S. stock market in general.

o Russell  2000  Growth  IndexR: An index of  common  stocks  designed  to track
  performance of small capitalization companies.

o S&P Midcap 400 IndexR: An index of common stocks designed to track performance
  of medium capitalization companies.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the  Fund's  operating  expenses  remain  the same as in the table
above.  The figures  shown would be the same whether or not you sold your shares
at the end of each  period.  Although  your actual costs may be higher or lower,
based on these assumptions your costs would be:

ADDITIONAL INFORMATION ABOUT THE 
FUND'S INVESTMENTS

Each portfolio may invest up to 100% of its assets in cash, high-grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets  from a  temporary  unacceptable  risk of loss,  rather than
directly to promote the portfolio's investment objective.

Other  securities  the  portfolios  may  invest in are  discussed  in the Fund's
Statement of Additional Information (see back cover).

The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other Year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

                                                                               7

SHAREHOLDER INFORMATION

DISTRIBUTOR

Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302

TRANSFER AGENT

Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolios is calculated as of the close of business (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of each  portfolio on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolios are valued on the basis of amortized cost.

The Fund  declares  and  pays  dividends  and  distributions  by the  portfolios
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distributions from these investment vehicles are taxable as ordinary
income at the rate applicable to each participant at the time of distribution.In
certain cases,  distributions  made to a participant  prior to the participant's
reaching  age  59-1/2  are  subject to a penalty  tax  equivalent  to 10% of the
distributed  amount,  in  addition  to the  ordinary  income tax payable on such
amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.


          NAV  (NET  ASSET  VALUE) IS   COMPUTED  BY   ADDING
         TOGETHER  THE  VALUE  OF  THE PORTFOLIO'S INVESTMENTS
        PLUS CASH AND OTHER ASSETS, SUBTRACTING ITS LIABILITIES
       AND  THEN  DIVIDING  THE  RESULT  BY  THE  NUMBER  OF ITS
                                             OUTSTANDING SHARES.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in a portfolio  directly,  but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.

FINANCIAL HIGHLIGHTS


The  financial  highlights  table  is  intended  to  help  you  understand  each
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).  The financial  highlights for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are
included in the Annual Report, which is available upon request.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS & PERFORMANCE

INVESTMENTS: THE ALGER AMERICAN FUND

The  investment  goal  and  primary  approach  of each  portfolio  is  discussed
individually below. All of the portfolios invest primarily in equity securities,
such as common or preferred stocks, which are listed on U.S. exchanges or in the
over-the-counter  market.  They invest primarily in "growth" stocks.  The Fund's
Manager, Fred Alger Management, Inc., believes that these companies tend to fall
into one of two categories:

o  High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o  Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

The company's market  capitalization  will dictate in which portfolio(s) it will
be  placed.  The  market  capitalization  of a  company  is its  price per share
multiplied by its number of outstanding shares.


ALGER AMERICAN SMALL CAPITALIZATION PORTFOLIO

GOAL

THE ALGER  AMERICAN  SMALL  CAPITALIZATION  PORTFOLIO  SEEKS  LONG-TERM  CAPITAL
APPRECIATION.


APPROACH

It focuses on small,  fast-growing  companies  that offer  innovative  products,
services  or  technologies  to a rapidly  expanding  marketplace.  Under  normal
circumstances, the portfolio invests primarily in the equity securities of small
capitalization  companies.  A small  capitalization  company  is one  that has a
market  capitalization within the range of the Russell(R) 2000 Growth Index or
the S&P(R) SmallCap 600 Index


ALGER AMERICAN MIDCAP GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN MIDCAP GROWTH PORTFOLIO SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on midsize  companies with promising growth  potential.  Under normal
circumstances,  the  portfolio  invests  primarily in the equity  securities  of
companies  having a market  capitalization  within the range of companies in the
S&P(R) MidCap 400 Index.


ALGER AMERICAN GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN GROWTH PORTFOLIO 
SEEKS LONG-TERM CAPITAL APPRECIATION.


APPROACH

It focuses on  companies  that  generally  have broad  product  lines,  markets,
financial  resources and depth of management.  Under normal  circumstances,  the
portfolio  invests  primarily in the equity  securities of large companies.  The
portfolio  considers  a large  company  to have a  market  capitalization  of $1
billion or greater.

PRINCIPAL RISKS


RISKS APPLICABLE TO ALL PORTFOLIOS

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your  investment is a risk of  investing.  A portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also,  a Fund  investment  may not  grow  as  fast as the  rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolios' investment styles and objectives, an investment in them
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

A portfolio's trading in some stocks may be relatively  short-term,  meaning the
Fund may buy a  security  and sell it a short time  later to take  advantage  of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase a portfolio's  realized  gains,  thereby  increasing  the amount of
taxable distributions to shareholders at the end of the year.

There may be additional risks applicable to a specific  portfolio because of its
investment approach.


RISKS APPLICABLE TO ALGER AMERICAN
SMALL CAPITALIZATION PORTFOLIO

A risk of investing in the portfolio is:

o the  possibility  of greater  risk by  investing  in  smaller,  less  seasoned
  companies rather than larger, more established companies owing to such factors
  as inexperienced management and limited financial resources


RISKS APPLICABLE TO ALGER AMERICAN
MIDCAP GROWTH PORTFOLIO

A risk of investing in the portfolio is:

o the possibility of greater risk by investing in medium-sized  companies rather
  than larger, more established companies owing to such factors as inexperienced
  management and limited financial resources


RISKS APPLICABLE TO ALGER AMERICAN GROWTH
PORTFOLIO

The portfolio's primary risks are those summarized above in "Risks Applicable to
All Portfolios."

PERFORMANCE

The following bar charts show the changes in the  portfolio's  performance  from
year to year and give you some indication of the risks of investing in the Fund.
They assume reinvestment of dividends and distributions. 

The Average  Annual Total Return tables compare a portfolio's  performance  over
several periods with that of an appropriate benchmark index. They assume

                                                                               3
<PAGE>

reinvestment of dividends and  distributions.  Remember that how a portfolio has
performed in the past is not necessarily an indication of how it will perform in
the future.

Each index used in the tables is a broad index  designed  to track a  particular
market or market  segment.  No expenses or fees are reflected in the returns for
the  indexes,   which  are  unmanaged.   All  returns  for  the  indexes  assume
reinvestment of dividends and interest of the underlying securities that make up
the respective index.

o S&P 500  IndexR: An index of large  company  common  stocks  considered  to be
  representative of the U.S. stock market in general.

o Russell 2000  Growth  IndexR:  An index of  common  stocks  designed  to track
  performance of small capitalization companies.

o S&P Midcap 400 IndexR: An index of common stocks designed to track performance
  of medium capitalization companies.

expenses  listed above, is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the  Fund's  operating  expenses  remain  the same as in the table
above.  The figures  shown would be the same whether or not you sold your shares
at the end of each  period.  Although  your actual costs may be higher or lower,
based on these assumptions your costs would be:

                      1 Year   3 Year  5 Year   10 Year

ADDITIONAL INFORMATION ABOUT
THE FUND'S INVESTMENTS

Each portfolio may invest up to 100% of its assets in cash, high-grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets  from a  temporary  unacceptable  risk of loss,  rather than
directly to promote the portfolio's investment objective.

Other  securities  the  portfolios  may  invest in are  discussed  in the Fund's
Statement of Additional Information (see back cover).

                                                                               5

MANAGEMENT AND ORGANIZATION

MANAGER

Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same manager since inception,  and
the  portfolios pay the Manager fees at these annual rates based on a percentage
of average daily net assets: Small Capitalization Portfolio--.85%; MidCap Growth
Portfolio--.80%; Growth Portfolio--.75%.


PORTFOLIO MANAGERS

David  Alger,  Seilai  Khoo,  Ron Tartaro and Steven  Thumm are the  individuals
responsible for the day-to-day  management of the portfolios'  investments.  Mr.
Alger,  a  manager  of all of the  portfolios  since  their  inception  has been
employed by the Manager as  Executive  Vice  President  and Director of Research
since 1971,  and as President  since 1995.  Ms. Khoo, a co-manager  of the Small
Capitalization Portfolio, has been employed by Alger Management since 1989, as a
senior research analyst until 1995 and as a Senior Vice President and co-manager
since  1995.  Mr.  Tartaro,  a  co-manager  of  the  MidCap  Growth  and  Growth
Portfolios,  has been  employed  by Alger  Management  since  1990,  as a senior
research  analyst until 1995 and as a Senior Vice President and co-manager since
1995. Steven Thumm serves as co-manager of the Balanced  Portfolio.  He has been
employed  by the Manager as a fixed  income  analyst  since 1991 and  co-manager
since 1995.

YEAR 2000 

The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other Year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

SHAREHOLDER INFORMATION

DISTRIBUTOR

Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302

TRANSFER AGENT

Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolios is calculated as of the close of business (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of each  portfolio on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolios are valued on the basis of amortized cost.

The Fund  declares  and  pays  dividends  and  distributions  by the  portfolios
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distributions from these investment vehicles are taxable as ordinary
income at the rate applicable to each participant at the time of distribution.In
certain cases,  distributions  made to a participant  prior to the participant's
reaching  age  59-1/2  are  subject to a penalty  tax  equivalent  to 10% of the
distributed  amount,  in  addition  to the  ordinary  income tax payable on such
amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.


          NAV  (NET  ASSET  VALUE) IS   COMPUTED  BY   ADDING
         TOGETHER  THE  VALUE  OF  THE PORTFOLIO'S INVESTMENTS
        PLUS CASH AND OTHER ASSETS, SUBTRACTING ITS LIABILITIES
       AND  THEN  DIVIDING  THE  RESULT  BY  THE  NUMBER  OF ITS
                                             OUTSTANDING SHARES.

PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in a portfolio  directly,  but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.

                                                                               7

FINANCIAL HIGHLIGHTS

The  financial  highlights  table  is  intended  to  help  you  understand  each
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).  The financial  highlights for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are
included in the Annual Report, which is available upon request.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS & PERFORMANCE

INVESTMENTS: THE ALGER AMERICAN FUND

The  investment  goal  and  primary  approach  of each  portfolio  is  discussed
individually  below. All of the portfolios (other than the fixed-income  portion
of the Income & Growth Portfolio) invest primarily in equity securities, such as
common or  preferred  stocks,  which  are  listed  on U.S.  exchanges  or in the
over-the-counter  market.  They invest primarily in "growth" stocks.  The Fund's
Manager, Fred Alger Management, Inc., believes that these companies tend to fall
into one of two categories:

o High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

The company's market  capitalization  will dictate in which portfolio(s) it will
be placed  in.  The  market  capitalization  of a company is its price per share
multiplied by its number of outstanding shares.

ALGER AMERICAN SMALL CAPITALIZATION PORTFOLIO

GOAL

THE ALGER AMERICAN SMALL CAPITALIZATION PORTFOLIO
SEEKS LONG-TERM CAPITAL APPRECIATION.

APPROACH

It focuses on small,  fast-growing  companies  that offer  innovative  products,
services  or  technologies  to a rapidly  expanding  marketplace.  Under  normal
circumstances, the portfolio invests primarily in the equity securities of small
capitalization  companies.  A small  capitalization  company  is one  that has a
market  capitalization  within the range of the Russell(R)  2000 Growth Index or
the S&P(R) SmallCap 600 Index.

ALGER AMERICAN GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN GROWTH PORTFOLIO SEEKS LONG-TERM CAPITAL APPRECIATION.

APPROACH

It focuses on  companies  that  generally  have broad  product  lines,  markets,
financial  resources and depth of management.  Under normal  circumstances,  the
portfolio  invests  primarily in the equity  securities of large companies.  The
portfolio  considers  a large  company  to have a  market  capitalization  of $1
billion or greater.

ALGER AMERICAN INCOME &GROWTH PORTFOLIO

GOAL

THE ALGER AMERICAN  INCOME &GROWTH  PORTFOLIO  PRIMARILY SEEKS TO PROVIDE A HIGH
LEVEL OF DIVIDEND INCOME; ITS SECONDARY GOAL IS TO PROVIDE CAPITAL APPRECIATION.

APPROACH

The portfolio  invests in dividend paying equity  securities,  such as common or
preferred  stocks,  preferably  those  which the  Manager  believes  also  offer
opportunities for capital appreciation.

PRINCIPAL RISKS

RISKS APPLICABLE TO ALL PORTFOLIOS

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your  investment is a risk of  investing.  A portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also,  a Fund  investment  may not  grow  as  fast as the  rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolios' investment styles and objectives, an investment in them
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

A portfolio's  trading in some stocks may be relatively  sort-term,  meaning the
Fund may buy a  security  and sell it a short time  later to take  advantage  of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase a portfolio's  realized  gains,  thereby  increasing  the amount of
taxable distributions to shareholders at the end of the year.

RISKS APPLICABLE TO ALGER AMERICAN
SMALL CAPITALIZATION PORTFOLIO

A risk of investing in the portfolio is:

o the  possibility  of greater  risk by  investing  in  smaller,  less  seasoned
  companies rather than larger, more established companies owing to such factors
  as inexperienced management and limited financial resources.


RISKS APPLICABLE TO ALGER AMERICAN
GROWTH PORTFOLIO

The portfolio's primary risks are those summarized above in "Risks Applicable to
All Portfolios".


RISKS APPLICABLE TO ALGER AMERICAN
INCOME & GROWTH PORTFOLIO

A risk of investing in the portfolio is:

o the  possibility  that  companies may cut or fail to declare  dividends due to
  market downturns or other reasons

PERFORMANCE

The following bar charts show the changes in the  portfolio's  performance  from
year to year and give you some indication of the risks of investing in the Fund.
They assume reinvestment of dividends and distributions.  

The Average  Annual Total Return tables compare a portfolio's  performance  over
several  periods  with  that of an  appropriate  benchmark  index.  They  assume

tributions.  Remember  that how a  portfolio  has  performed  in the past is not
necessarily an indication of how it will perform in the future.

Each index used in the tables is a broad index  designed  to track a  particular
market or market  segment.  No expenses or fees are reflected in the returns for
the  indexes,   which  are  unmanaged.   All  returns  for  the  indexes  assume
reinvestment of dividends and interest of the underlying securities that make up
the respective index.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the  Fund's  operating  expenses  remain  the same as in the table
above.

The figures  shown would be the same  whether or not you sold your shares at the
end of each period.  Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

ADDITIONAL INFORMATION ABOUT
THE FUND'S INVESTMENTS

Each portfolio may invest up to 100% of its assets in cash, high-grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets  from a  temporary  unacceptable  risk of loss,  rather than
directly to promote the portfolio's investment objective.

Other  securities  the  portfolios  may  invest in are  discussed  in the Fund's
Statement of Additional Information (see back cover).

MANAGEMENT AND ORGANIZATION

MANAGER

Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same manager since inception,  and
the  portfolios pay the Manager fees at these annual rates based on a percentage
of daily net assets: Small Capitalization Portfolio -- .85%; Growth Portfolio --
 .75%; Income & Growth Portfolio-- .625%.


PORTFOLIO MANAGERS

David  Alger,  Seilai  Khoo,  Ron Tartaro and Steven  Thumm are the  individuals
responsible for the day-to-day  management of the portfolios'  investments.  Mr.
Alger,  a manager of all of the  portfolios,  since  their  inception,  has been
employed by the Manager as  Executive  Vice  President  and Director of Research
since 1971,  and as  President  since 1995.  Ms.  Khoo, a comanager of the Small
Capitalization Portfolio, has been employed by Alger Management since 1989, as a
senior research  analyst until 1995 and as a Senior Vice President and comanager
since 1995. Mr. Tartaro,  a comanager of the Growth,  Growth and Income & Growth
Portfolios,  has been  employed  by Alger  Management  since  1990,  as a senior
research  analyst until 1995 and as a Senior Vice President and comanager  since
1995.  Steven Thumm serves as comanager of the Balanced  Portfolio.  He has been
employed by the Manager as a fixed income analyst since 1991.

YEAR 2000
The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

SHAREHOLDER INFORMATION

DISTRIBUTOR
Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302

TRANSFER AGENT
Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolios is calculated as of the close of business (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of each  portfolio on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolios are valued on the basis of amortized cost.

The Fund  declares  and  pays  dividends  and  distributions  by the  portfolios
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of both realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distributions from these investment vehicles are taxable as ordinary
income at the rate applicable to each participant at the time of distribution.In
certain cases,  distributions  made to a participant  prior to the participant's
reaching  age 59 1/2 are  subject  to a  penalty  tax  equivalent  to 10% of the
distributed  amount,  in  addition  to the  ordinary  income tax payable on such
amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.


NAV  (net  asset  value)  is  computed  by  adding  together  the  value  of the
portfolio's investments plus cash and other assets,  subtracting its liabilities
and then dividing the result by the number of its outstanding shares.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in a portfolio  directly,  but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.



                                                                               7

FINANCIAL HIGHLIGHTS

The  financial  highlights  table  is  intended  to  help  you  understand  each
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).  The financial  highlights for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are
included in the Annual Report, which is available upon request.

THE ALGER AMERICAN FUND--ALGER
AMERICAN SMALL CAPITALIZATION PORTFOLIO

RISK/RETURN SUMMARY: INVESTMENTS, RISKS & PERFORMANCE

INVESTMENT GOAL AND APPROACH

THE ALGER  AMERICAN  SMALL  CAPITALIZATION  PORTFOLIO  SEEKS  LONG-TERM  CAPITAL
APPRECIATION.

It invests primarily in equity  securities,  such as common or preferred stocks,
which are  listed  on U.S.  exchanges  or in the  over-the-counter  market.  The
portfolio invests primarily in "growth" stocks.  The portfolio's  Manager,  Fred
Alger Management,  Inc.,  believes that these companies tend to fall into one of
two categories:

[] High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

[] Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

It focuses on small,  fast-growing  companies  that offer  innovative  products,
services  or  technologies  to a rapidly  expanding  marketplace.  Under  normal
circumstances, the portfolio invests primarily in the equity securities of small
capitalization  companies.  A small  capitalization  company  is one  that has a
market  capitalization  within the range of the Russell(R)  2000 Growth Index or
the S&P(R) SmallCap 600 Index.


[GRAPHIC OMITTED]

PRINCIPAL RISKS

A risk of investing in the portfolio is:

[]  The  possibility  of greater  risk by investing  in smaller,  less  seasoned
    companies  rather than  larger,  more  established  companies  owing to such
    factors as inexperienced management and limited financial resources..

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your investment is a risk of investing.  The portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also, a portfolio  investment  may not grow as fast as the rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolio's  investment styles and objectives,  an investment in it
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

The  portfolio's  trading in some stocks may be relatively  short-term,  meaning
that it may buy a security  and sell it a short time later to take  advantage of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other 


2
<PAGE>

expenses.  In  addition,  a high level of  short-term  trading may  increase the
portfolio's   realized   gains,   thereby   increasing  the  amount  of  taxable
distributions to shareholders at the end of the year.

PERFORMANCE

The following bar chart shows the changes in the  portfolio's  performance  from
year to year and gives you some  indication  of the  risks of  investing  in the
portfolio.  It assumes  reinvestment of dividends and  distributions.  The table
beneath it compares the  portfolio's  performance  over  several  periods with a
broad measure of market performance.  The performance  reflects  reinvestment of
dividends and  distributions.  Remember that the portfolio's  performance in the
past is not necessarily an indication of how it will perform in the future.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the portfolio with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the portfolio's operating expenses remain the same as in the table
above.  The figures  shown would be the same whether or not you sold your shares
at the end of each  period.  Although  your actual costs may be higher or lower,
based on these assumptions your costs would be:

                                1 Year   3 Year   5 Year   10 Year

The example above does not reflect charges and deductions  which are, or may be,
imposed under variable annuity contracts,  variable life insurance policies,  or
pension or retirement  plans.  Such charges and  deductions are described in the
prospectus  for the contract or policy  accompanying  this  prospectus or in the
Plan documents.

ADDITIONAL INFORMATION ABOUT THE PORTFOLIO'S INVESTMENTS

The portfolio may invest up to 100% of its assets in cash,  high grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets from loss,  rather than directly to promote the  portfolio's
investment objective.

MANAGEMENT AND ORGANIZATION

MANAGER

Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same manager since inception,  and
the portfolio pays the Manager a fee at the annual rate based on a percentage of
average daily net assets of .85%.

PORTFOLIO MANAGERS

David Alger and Seilai Khoo are the  individuals  responsible for the day-to-day
management of portfolio investments. Mr. Alger, a manager of the portfolio since
its inception,  has been employed by the Manager as Executive Vice President and
Director of Research since 1971, and as President since 1995. Ms. Khoo has

<PAGE>

been employed by Alger Management since 1989, as a senior research analyst until
1995 and as a Senior Vice President and comanager since 1995.

YEAR 2000
The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that the shareholders'  investments in the Fund
will be  impacted  negatively  as a result of the Fund's  Year 2000  transition.
However, people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

TRANSFER AGENT

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolio is calculated as of the close of business  (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of the  portfolio  on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolio are valued on the basis of amortized cost.

The  Fund  declares  and  pays  dividends  and  distributions  by the  portfolio
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized 


                                                                               5

capital gains until they receive a distribution of the dividends from their plan
accounts. Generally, distributions from these investment vehicles are taxable as
ordinary  income  at the  rate  applicable  to each  participant  at the time of
distribution.In certain cases,  distributions made to a participant prior to the
participant's reaching age 59-1/2 are subject to a penalty tax equivalent to 10%
of the  distributed  amount,  in addition to the ordinary  income tax payable on
such amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.





                               NAV (NET  ASSET  VALUE)  IS  COMPUTED  BY  ADDING
                      TOGETHER  THE  VALUE  OF  THE     PORTFOLIO'S  INVESTMENTS
                 PLUS  CASH  AND  OTHER  ASSETS,   SUBTRACTING  ITS     LIABILI-
                            TIES  AND THEN  DIVIDING THE RESULT BY THE NUMBER OF
                                                    ITS  OUTSTANDING     SHARES.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in the portfolio directly, but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.

FINANCIAL HIGHLIGHTS


The  financial   highlights  table  is  intended  to  help  you  understand  the
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).The  financial  highlights  for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are

RISK/RETURN SUMMARY: 
INVESTMENTS, RISKS & PERFORMANCE

THE ALGER AMERICAN FUND--
ALGER AMERICAN GROWTH PORTFOLIO


INVESTMENT GOAL AND APPROACH

THE ALGER AMERICAN GROWTH PORTFOLIO 
SEEKS LONG-TERM CAPITAL APPRECIATION.

It invests primarily in equity  securities,  such as common or preferred stocks,
which are  listed  on U.S.  exchanges  or in the  over-the-counter  market.  The
portfolio invests primarily in "growth" stocks.  The portfolio's  Manager,  Fred
Alger Management,  Inc.,  believes that these companies tend to fall into one of
two categories:

o  High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o  Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

It focuses on  companies  that  generally  have broad  product  lines,  markets,
financial  resources and depth of management.  Under normal  circumstances,  the
portfolio  invests  primarily in the equity  securities of large companies.  The
portfolio  considers  a large  company  to have a  market  capitalization  of $1
billion or greater.


[GRAPHIC OMITTED]

PRINCIPAL RISKS

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your investment is a risk of investing.  The portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also, a portfolio  investment  may not grow as fast as the rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolio's  investment  style and objectives,  an investment in it
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

The  portfolio's  trading in some stocks may be relatively  short-term,  meaning
that it may buy a security  and sell it a short time later to take  advantage of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase the portfolio's  realized gains,  thereby  increasing the amount of
taxable distributions to shareholders at the end of the year.

PERFORMANCE

The following bar chart shows the portfolio's  performance from year to year and
give you some  indication of the risks of investing in the portfolio.  The table
beneath it compares the  portfolio's  performance  over  several  periods with a
broad measure of market  performance.  They assume reinvestment of dividends and
distributions.  Remember that how the portfolio has performed in the past is not
necessarily an indication of how it will perform in the future.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the portfolio with the cost of investing in other mutual funds.

The  example  assumes  that you  invest  $10,000 in the  portfolio  for the time
periods indicated. The example also assumes that your investment has a 5% return
each year and that the portfolio's  operating expenses remain the same as in the
table  above.  The figures  shown would be the same whether or not you sold your
shares at the end of each  period.  Although  your actual costs may be higher or
lower, based on these assumptions your costs would be:

The example above does not reflect charges and deductions  which are, or may be,
imposed under variable annuity contracts,  variable life insurance policies,  or
pension or retirement  plans.  Such charges and  deductions are described in the
prospectus  for the contract or policy  accompanying  this  prospectus or in the
Plan documents.


ADDITIONAL INFORMATION ABOUT
THE PORTFOLIO'S INVESTMENTS

The portfolio may invest up to 100% of its assets in cash,  high grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets from loss,  rather than directly to promote the  portfolio's
investment objective.

Other  securities  the  portfolio  may  invest in are  discussed  in the  Fund's
Statement of Additional Information (see back cover).

MANAGEMENT AND ORGANIZATION


MANAGER

Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same manager since inception,  and
the  portfolio  pays the Manager Fee at the annual rate based on a percentage of
average daily net assets of .75%.


PORTFOLIO MANAGERS

David Alger and Ron Tartaro are the  individuals  responsible for the day-to-day
management of portfolio investments. Mr. Alger, a manager of all the portfolios

4

<PAGE>


since  their  inception,  has been  employed by the  Manager as  Executive  Vice
President and Director of Research since 1971, and as President  since 1995. Mr.
Tartaro has been employed by Alger  Management  since 1990, as a senior research
analyst until 1995 and as a Senior Vice President and comanager since 1995.

YEAR 2000

The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other Year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

SHAREHOLDER INFORMATION

DISTRIBUTOR
Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302

TRANSFER AGENT
Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolios is calculated as of the close of business (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends and various national holidays.

The Fund  generally  values the assets of the  portfolio  on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolio are valued on the basis of amortized cost.

The  Fund  declares  and  pays  dividends  and  distributions  by the  portfolio
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distributions
                                                                               5
<PAGE>

from  these  investment  vehicles  are  taxable as  ordinary  income at the rate
applicable to each  participant at the time of  distribution.  In certain cases,
distributions  made to a  participant  prior to the  participant's  reaching age
59-1/2 are subject to a penalty tax equivalent to 10% of the distributed amount,
in addition to the ordinary income tax payable on such amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.


          NAV  (NET  ASSET  VALUE) IS   COMPUTED  BY   ADDING
         TOGETHER  THE  VALUE  OF  THE PORTFOLIO'S INVESTMENTS
        PLUS CASH AND OTHER ASSETS, SUBTRACTING ITS LIABILITIES
       AND  THEN  DIVIDING  THE  RESULT  BY  THE  NUMBER  OF ITS
                                             OUTSTANDING SHARES.

PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in the portfolio directly, but may do so only through one of these

FINANCIAL HIGHLIGHTS


The  financial  highlights  table  is  intended  to  help  you  understand  each
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).  The financial  highlights for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are
included in the Annual Report, which is available upon request.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS & PERFORMANCE

THE ALGER AMERICAN FUND-ALGER
AMERICAN INCOME & GROWTH PORTFOLIO

INVESTMENT GOAL AND APPROACH

THE ALGER AMERICAN  INCOME & GROWTH  PORTFOLIO  SEEKS TO PROVIDE A HIGH LEVEL OF
DIVIDEND INCOME; ITS SECONDARY GOAL IS TO PROVIDE CAPITAL APPRECIATION.

It invests primarily in equity  securities,  such as common or preferred stocks,
which are  listed  on U.S.  exchanges  or in the  over-the-counter  market.  The
portfolio invests primarily in "growth" stocks.  The portfolio's  Manager,  Fred
Alger Management,  Inc.,  believes that these companies tend to fall into one of
two categories:

o High Unit Volume Growth
  Vital, creative companies which offer goods or services to a rapidly expanding
  marketplace. They include both established and emerging firms, offering new or
  improved  products,  or firms simply  fulfilling  an  increased  demand for an
  existing line.

o Positive Life Cycle Change
  Companies   experiencing   a  major   change  which  is  expected  to  produce
  advantageous  results.  These  changes  may be as  varied  as new  management,
  products  or  technologies;  restructuring  or  reorganization;  or merger and
  acquisition.

  The portfolio invests in dividend paying equity securities,  such as common or
  preferred  stocks,  preferably  those  which the Manager  believes  also offer
  opportunities for capital appreciation.


[GRAPHIC OMITTED]

PRINCIPAL RISKS

A risk of investing in the portfolio is:

o the  possibility  that  companies may cut or fail to declare  dividends due to
  market downturns or other reasons.

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your investment is a risk of investing.  The portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also, a portfolio  investment  may not grow as fast as the rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolio's  investment styles and objectives,  an investment in it
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

The  portfolio's  trading in some stocks may be relatively  short-term,  meaning
that it may buy a security  and sell it a short time later to take  advantage of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase the portfolio's  realized gains,  thereby  increasing the amount of
taxable distributions to shareholders at the end of the year.

PERFORMANCE

The following bar chart shows the changes in the  portfolio's  performance  from
year to year and gives you some  indication  of the  risks of  investing  in the
portfolio.  It assumes  reinvestment of dividends and  distributions.  The table
beneath it compares the  portfolio's  performance  over  several  periods with a
broad measure of market performance.  The performance  reflects  reinvestment of
dividends and  distributions.  Remember that the portfolio's  performance in the
past is not necessarily an indication of how it will perform in the future.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the portfolio with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the portfolio's operating expenses remain the same as in the table
above.  The figures  shown would be the same whether or not you sold your shares
at the end of each  period.  Although  your actual costs may be higher or lower,
based on these assumptions your costs would be:

The example above does not reflect charges and deductions  which are, or may be,
imposed under variable annuity contracts,  variable life insurance policies,  or
pension or retirement  plans.  Such charges and  deductions are described in the

ADDITIONAL INFORMATION ABOUT THE PORTFOLIO'S INVESTMENTS

The portfolio may invest up to 100% of its assets in cash,  high grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets from loss,  rather than directly to promote the  portfolio's
investment objective.

Other  securities  the  portfolio  may  invest in are  discussed  in the  Fund's
Statement of Additional Information (see back cover).

MANAGEMENT AND ORGANIZATION

MANAGER

Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same Manager since inception,  and
the portfolio pays the manager a fee at the annual rate based on a percentage of
average daily net assets of .625%.

<PAGE>
PORTFOLIO MANAGERS

David Alger and Ron Tartaro are the  individuals  responsible for the day-to-day
management  of the  portfolios'  investments.  Mr.  Alger,  a  comanager  of the
portfolio  since its  inception,  has been  employed by the Manager as Executive
Vice President and Director of Research since 1971, and as President since 1995.
Mr.  Tartaro has been  employed  by Alger  Management  since  1990,  as a senior
research  analyst  until 1995 and as a Senior Vice  President  and manager since
1995.


YEAR 2000

The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

SHAREHOLDER INFORMATION

DISTRIBUTOR
Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302

TRANSFER AGENT
Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolio is calculated as of the close of business  (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally, the Exchange is.
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of the  portfolio  on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolio are valued on the basis of amortized cost.



                                                                               5

The  Fund  declares  and  pays  dividends  and  distributions  by the  portfolio
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distributions from these investment vehicles are taxable as ordinary
income at the rate applicable to each participant at the time of distribution.In
certain cases,  distributions  made to a participant  prior to the participant's
reaching  age 59 1/2 are  subject  to a  penalty  tax  equivalent  to 10% of the
distributed  amount,  in  addition  to the  ordinary  income tax payable on such
amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.


NAV  (net  asset  value)  is  computed  by  adding  together  the  value  of the
portfolio's investments plus cash and other assets,  subtracting its liabilities
and then dividing the result by the number of its outstanding shares.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in the portfolio directly, but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.

FINANCIAL HIGHLIGHTS

The  financial   highlights  table  is  intended  to  help  you  understand  the
portfolio's  financial  performance for the periods shown.  Certain  information
reflects  financial  results for a single Fund share.  The total  returns in the
table  represent  the rate  that an  investor  would  have  earned or lost on an
investment   in  the  Fund   (assuming   reinvestment   of  all   dividends  and
distributions).  The financial  highlights for the years ended December 31, 1990
through 1998 have been audited by Arthur  Andersen  LLP, the Fund's  independent
public accountants. The financial highlights, with the exception of total return
information,  for the  year  ended  December  31,  1989  were  audited  by other
independent  accountants,  who have  expressed an unqualified  opinion  thereon.
Arthur  Andersen's  report,  along with the  Fund's  financial  statements,  are
included in the Annual Report, which is available upon request.

THE ALGER AMERICAN FUND-ALGER AMERICAN
MIDCAP GROWTH PORTFOLIO

RISK/RETURN SUMMARY: INVESTMENTS,
RISKS & PERFORMANCE

INVESTMENT GOAL AND APPROACH

THE ALGER AMERICAN MIDCAP GROWTH PORTFOLIO SEEKS LONG-TERM CAPITAL APPRECIATION.

It invests primarily in equity  securities,  such as common or preferred stocks,
which are  listed  on U.S.  exchanges  or in the  over-the-counter  market.  The
portfolio invests primarily in "growth" stocks.  The portfolio's  Manager,  Fred
Alger Management,  Inc.,  believes that these companies tend to fall into one of
two categories:

o  High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o  Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

It focuses on midsize  companies with promising growth  potential.  Under normal
circumstances,  the  portfolio  invests  primarily in the equity  securities  of
companies  having a market  capitalization  within the range of companies in the
S&P(R) MidCap 400 Index.

The portfolio may invest up to 100% of its assets in cash,  high-grade bonds, or
cash  equivalents for temporary  defensive  reasons if the manager believes that
adverse market or other conditions  warrant such a strategy.  This is to protect
the Fund's  assets  from a  temporary  unacceptable  risk of loss,  rather  than
directly to promote the portfolio's investment objective.

The portfolio may appeal to investors who seek long-term  capital growth and can
tolerate fluctuations in their investment's value.


[GRAPHIC OMITTED]

PRINCIPAL RISKS

The risk of investing in the portfolio is:

o  the possibility of greater risk by investing in medium-sized companies rather
   than  larger,   more   established   companies   owing  to  such  factors  as
   inexperienced management and limited financial resources.

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your investment is a risk of investing.  The portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also, a portfolio  investment  may not grow as fast as the rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market, political and


2

<PAGE>


economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolio's  investment styles and objectives,  an investment in it
may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

A portfolio's trading in some stocks may be relatively short-term,  meaning that
it may buy a  security  and  sell it a short  time  later to take  advantage  of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase a portfolio's  realized  gains,  thereby  increasing  the amount of
taxable distributions to shareholders at the end of the year.

PERFORMANCE

The following bar chart shows the changes in the  portfolio's  performance  from
year to year and gives you some  indication  of the  risks of  investing  in the
portfolio.  It assumes  reinvestment of dividends and  distributions.  The table
beneath it compares the  portfolio's  performance  over  several  periods with a
broad measure of market performance.  The performance  reflects  reinvestment of
dividends and  distributions.  Remember that the portfolio's  performance in the
past is not necessarily an indication of how it will perform in the future.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the Portfolio with the cost of investing in other mutual funds.

The  example  assumes  that you  invest  $10,000 in the  Portfolio  for the time
periods indicated. The example also assumes that your investment has a 5% return
each year and that the Portfolio  operating  expenses  remain the same as in the
table  above.  The figures  shown would be the same whether or not you sold your
shares at the end of each  period.  Although  your actual costs may be higher or
lower, based on these assumptions your costs would be:

The example above does not reflect charges and deductions  which are, or may be,
imposed under variable annuity contracts,  variable life insurance policies,  or
pension or retirement  plans.  Such charges and  deductions are described in the
prospectus  for the contract or policy  accompanying  this  prospectus or in the
Plan documents.


ADDITIONAL INFORMATION ABOUT THE PORTFOLIO'S INVESTMENTS

The portfolio may invest up to 100% of its assets in cash,  high grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets from loss,  rather than directly to promote the  portfolio's
investment objective. Other securities the portfolio may invest in are discussed
in the Fund's Statement of Additional Information (see back cover).

MANAGEMENT AND ORGANIZATION

MANAGER
Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same manager since inception,  and
the portfolio pays the Manager a fee at the annual rate based on a percentage of
average daily net assets of .80%.

<PAGE>

PORTFOLIO MANAGERS

David Alger and Ron Tartaro are the  individuals  responsible for the day-to-day
management of the portfolios' investments. Mr. Alger, a manager of the portfolio
since  its  inception,  has been  employed  by the  Manager  as  Executive  Vice
President and Director of Research since 1971, and as President  since 1995. Mr.
Tartaro,  has been employed by Alger Management since 1990, as a senior research
analyst until 1995 and as a Senior Vice President and comanager since 1995.

YEAR 2000

The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently, it is not anticipated that shareholders' in the Fund investments will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

SHAREHOLDER INFORMATION

DISTRIBUTOR

Fred Alger & Company, Incorporated
30 Montgomery Street
Jersey City, NJ 07302

TRANSFER AGENT
Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolio is calculated as of the close of business  (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of the  portfolio  on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolio are valued on the basis of amortized cost.

The  Fund  declares  and  pays  dividends  and  distributions  by the  portfolio
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.


                                                                               5

<PAGE>



Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distributions from these investment vehicles are taxable as ordinary
income at the rate applicable to each participant at the time of distribution.In
certain cases,  distributions  made to a participant  prior to the participant's
reaching  age  59-1/2  are  subject to a penalty  tax  equivalent  to 10% of the
distributed  amount,  in  addition  to the  ordinary  income tax payable on such
amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.

                                     NAV (NET ASSET VALUE) IS COMPUTED BY ADDING
                               TOGETHER THE VALUE OF THE PORTFOLIO'S INVESTMENTS
                            PLUS CASH AND OTHER ASSETS, SUBTRACTING ITS LIABILI-
                              TIES AND THEN DIVIDING THE RESULT BY THE NUMBER OF
                                                         ITS OUTSTANDING SHARES.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in a portfolio  directly,  but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.

THE ALGER AMERICAN FUND--ALGER
AMERICAN LEVERAGED ALLCAP PORTFOLIO

RISK/RETURN SUMMARY: INVESTMENTS,
RISKS & PERFORMANCE

INVESTMENT GOAL AND APPROACH

THE  ALGER  AMERICAN   LEVERAGED  ALLCAP   PORTFOLIO  SEEKS  LONG-TERM   CAPITAL
APPRECIATION.

It invests primarily in equity  securities,  such as common or preferred stocks,
which are  listed  on U.S.  exchanges  or in the  over-the-counter  market.  The
portfolio invests primarily in "growth" stocks.  The portfolio's  Manager,  Fred
Alger Management,  Inc.,  believes that these companies tend to fall into one of
two categories:

o  High Unit Volume Growth

   Vital,  creative  companies  which  offer  goods  or  services  to a  rapidly
   expanding  marketplace.  They include both  established  and emerging  firms,
   offering new or improved  products,  or firms simply  fulfilling an increased
   demand for an existing line.

o  Positive Life Cycle Change

   Companies   experiencing   a  major  change  which  is  expected  to  produce
   advantageous  results.  These  changes  may be as varied  as new  management,
   products or  technologies;  restructuring  or  reorganization;  or merger and
   acquisition.

Under normal  circumstances,  the portfolio  invests in the equity securities of
companies of any size which demonstrate promising growth potential.

The portfolio can leverage, that is, borrow money, to buy additional securities.
By borrowing  money,  the portfolio has the potential to increase its returns if
the  increase  in the  value of the  securities  purchased  exceeds  the cost of
borrowing, including interest paid for the money borrowed.


[GRAPHIC OMITTED]

PRINCIPAL RISKS

A risk of investing in the portfolio is:

o  The risk that the cost of borrowing money to leverage will exceed the returns
   for the securities purchased or that the securities purchased may actually go
   down in value;  thus,  the  portfolio's  net asset  value can  decrease  more
   quickly than if the portfolio had not borrowed.

As with any fund that invests in stocks,  your  investment will go up or down in
value,  and the loss of your investment is a risk of investing.  The portfolio's
price per share  will  fluctuate  due to  changes  in the  market  prices of its
investments.  Also, a portfolio  investment  may not grow as fast as the rate of
inflation and stocks tend to be more volatile  than some other  investments  you
could make, such as bonds.  Furthermore,  the returns of a fund concentrating on
"growth"  stocks  tend to vary more  widely  over time than  those of funds that
focus on "value"  stocks;  prices of growth stocks tend to be higher in relation
to their companies' earnings and may be more sensitive to market,  political and
economic  developments  than other  stocks,  making their prices more  volatile.
Based on the portfolio's investment styles and objectives, an investment in it


2

<PAGE>

may be better  suited to investors  who seek  long-term  capital  growth and can
tolerate fluctuations in their investment's value.

The  portfolio's  trading in some stocks may be relatively  short-term,  meaning
that it may buy a security  and sell it a short time later to take  advantage of
current  gains if it is  believed  that an  alternative  investment  may provide
greater future growth.  This activity may create higher transaction costs due to
commissions and other expenses.  In addition, a high level of short-term trading
may increase the portfolio's  realized gains,  thereby  increasing the amount of
taxable distributions to shareholders at the end of the year.

PERFORMANCE

The following bar chart shows the changes in the  portfolio's  performance  from
year to year and gives you some  indication  of the  risks of  investing  in the
portfolio.  It assumes  reinvestment of dividends and  distributions.  The table
beneath it compares the  portfolio's  performance  over  several  periods with a
broad measure of market performance.  The performance  reflects  reinvestment of
dividends and  distributions.  Remember that the portfolio's  performance in the
past is not necessarily an indication of how it will perform in the future.

EXAMPLE

The  following  example,  which  reflects  the  shareholder  fees and  operating
expenses  listed above, is intended to help you compare the cost of investing in
the portfolio with the cost of investing in other mutual funds.

The example  assumes  that you invest  $10,000 in the Fund for the time  periods
indicated.  The example also assumes that your  investment  has a 5% return each
year and that the portfolio's operating expenses remain the same as in the table
above.  The figures  shown would be the same whether or not you sold your shares
at the end of each  period.  Although  your actual costs may be higher or lower,
based on these assumptions your costs would be:

The example above does not reflect charges and deductions  which are, or may be,
imposed under variable annuity contracts,  variable life insurance policies,  or
pension or retirement  plans.  Such charges and  deductions are described in the
prospectus  for the contract or policy  accompanying  this  prospectus or in the
Plan documents.

ADDITIONAL INFORMATION ABOUT THE PORTFOLIO'S INVESTMENTS

The portfolio may invest up to 100% of its assets in cash,  high grade bonds, or
cash  equivalents for temporary  defensive  reasons if the Manager believes that
adverse market or other  conditions  warrant.  This is to attempt to protect the
portfolio's  assets from loss,  rather than directly to promote the  portfolio's
investment objective.

Other  securities  the  portfolio's  may invest in are  discussed  in the Fund's
Statement of Additional Information (see back cover).

MANAGEMENT AND ORGANIZATION

MANAGER

Fred Alger Management, Inc.
1 World Trade Center
Suite 9333
New York, NY 10048

The Manager has been an investment  adviser since 1964, and manages  investments
totaling  (at  12/31/98)  $6.64  billion in mutual  fund assets as well as $3.95
billion in other assets. The Fund has had the same Manager since inception,  and
the portfolio pays the Manager a fee at the annual rate based on a percentage of
average daily net assets of .85%.

PORTFOLIO MANAGERS

David Alger and Ron Tartaro are the  individuals  responsible for the day-to-day
management of the portfolios' investments. Mr. Alger, a manager of the


4

<PAGE>



portfolio  since its  inception,  has been  employed by the Manager as Executive
Vice President and Director of Research since 1971, and as President since 1995.
Mr.  Tartaro has been  employed  by Alger  Management  since  1990,  as a senior
research  analyst until 1995 and as a Senior Vice President and co-manager since
1995.

YEAR 2000

The  Fund's  Manager  and  Distributor  have  advised  the  Fund  that  they are
implementing  a Year 2000 plan to  address  any  issues  arising  from  computer
systems' potentially erroneous reading of dates in the year 2000.  Specifically,
they are in the process of  confirming  that the Fund's  service  providers  are
resolving any Year 2000 issues as the millennium approaches.  While there can be
no  assurance  that  there  will be no  impairment  of  services  at that  time,
currently it is not anticipated that shareholders'  investments in the Fund will
be impacted negatively as a result of the Fund's Year 2000 transition.  However,
people and resources have been devoted to this important review.

Year 2000 issues, real or perceived, may also adversely affect stock prices. The
Manager intends to review SEC filings and other Year 2000 readiness  information
from companies in which the Fund may invest significantly,  as well as readiness
information  from  other  sources.  The  Manager  and the Fund have no reason to
believe that such measures  will not be  sufficient to avoid a material  adverse
effect on the Fund's  investments,  although there can be no assurance that they
will be.

Jersey City, NJ 07302

TRANSFER AGENT
Alger Shareholder Services, Inc.
30 Montgomery Street
Jersey City, NJ 07302

The  price of one  share  is its  "net  asset  value",  or NAV.  The NAV for the
portfolio is calculated as of the close of business  (normally 4:00 p.m. Eastern
time) every day the New York Stock Exchange is open. Generally,  the Exchange is
closed on weekends  and various  national  holidays.  It may close on other days
from time to time.

The Fund  generally  values the assets of the  portfolio  on the basis of market
quotations or, where market quotations are not readily  available,  on the basis
of fair value as  determined  by the  Manager  under  procedures  adopted by the
Fund's  Board of  Trustees.  Short-term  money  market  instruments  held by the
portfolio are valued on the basis of amortized cost.

The  Fund  declares  and  pays  dividends  and  distributions  by the  portfolio
annually.  The Fund  expects  that these annual  payments to  shareholders  will
consist of realized capital gains and net investment income.

Participants in variable annuity  contracts,  variable life insurance  policies,
and qualified  pension and retirement  plans  ordinarily  will not be subject to
taxation on dividends from net investment  income and net realized capital gains
until they receive a  distribution  of the dividends  from their plan  accounts.
Generally,  distribu-

                                                                               5

tions from these investment  vehicles are taxable as ordinary income at the rate
applicable to each  participant  at the time of  distribution.In  certain cases,
distributions  made to a participant prior to the participant's  reaching age 59
1/2 are subject to a penalty tax equivalent to 10% of the distributed amount, in
addition to the ordinary income tax payable on such amount.

Because  everyone's  tax situation is unique,  see a tax advisor about  federal,
state and local tax consequences of investing in the Fund.

                                    NAV (NET ASSET  VALUE) IS COMPUTED BY ADDING
                               TOGETHER THE VALUE OF THE PORTFOLIO'S INVESTMENTS
                           PLUS CASH AND OTHER ASSETS,  SUBTRACTING ITS LIABILI-
                              TIES AND THEN DIVIDING THE RESULT BY THE NUMBER OF
                                                         ITS OUTSTANDING SHARES.


PURCHASING AND REDEEMING FUND SHARES

The Fund is an investment  vehicle for variable  annuity  contracts and variable
life  insurance  policies  offered by the  separate  accounts of life  insurance
companies,  as well as qualified  pension and  retirement  plans.  An individual
cannot invest in a portfolio  directly,  but may do so only through one of these
sources.  The Fund's  shares are held in the names of the separate  accounts and
plans.

Shares of the Fund can be  purchased  or  redeemed on any day the New York Stock
Exchange is open.  They will be processed at the NAV next  calculated  after the
purchase or redemption  request is received in good order by the transfer agent.
All orders for purchase of shares are subject to acceptance or redemption by the
Fund or its Transfer  Agent.  The Transfer Agent pays for  redemptions  within 7
days after it accepts a redemption request.

The Fund may redeem some shares "in kind", which means that some of the proceeds
will be paid with securities the Fund owns instead of cash.

THE PORTFOLIOS

ALGER AMERICAN BALANCED PORTFOLIO
The  investment  objectives of the  Portfolio  are 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 Fred Alger
Management,  Inc. ("Alger Management"),  the Fund's investment manager, 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 total assets) during temporary defensive periods.

ALGER AMERICAN INCOME AND GROWTH PORTFOLIO
The primary investment  objective of the Portfolio is to provide a high level of
dividend income. Capital appreciation is a secondary investment objective of the
Portfolio.  Except during temporary defensive periods, the Portfolio attempts to
invest 100%, and it is a fundamental  policy of the Portfolio to invest at least
65%, of its total  assets in dividend  paying  equity  securities.  In selecting
among dividend paying equity securities,  Alger Management will favor securities
it believes also offer opportunities for capital appreciation. 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 total assets) during
temporary defensive periods.

ALGER AMERICAN 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,  have "total  market  capitalization"--present  market value per share
multiplied  by the  total  number  of  shares  outstanding--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.  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 of this combined range, and
in excess of that amount (up to 100% of its assets) during  temporary  defensive
periods.

ALGER AMERICAN 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  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 AMERICAN 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.  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 AMERICAN LEVERAGED ALLCAP 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 gains 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 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.

IN GENERAL
In order to afford the  Portfolios  the  flexibility  to take  advantage  of new
opportunities for investments in accordance with their investment  objectives or
to meet redemptions,  they may each hold up to 15% (or a higher percentage where
so stated) of their total  assets in money  market  instruments  and  repurchase
agreements  and in  excess of that  amount  (up to 100% of their  total  assets)
during  temporary  defensive  periods.  These  amounts  may be higher than those
maintained by other funds with similar investment objectives.


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.  There is no guarantee that any
Portfolio's objectives will be achieved.

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 debt 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 Fred
Alger Management,  Inc. ("Alger Management"),  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 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 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 were to default 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 AMERICAN 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 consisting of cash
or  liquid  securities  that  at all  times  are in an  amount  equal  to  their
obligations under reverse repurchase  agreements.  The Portfolio will invest the
proceeds in 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 less liabilities  other
than the repurchase obligation.

FIRM COMMITMENT AGREEMENTS AND
WHEN-ISSUED PURCHASES
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 a 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.  A
Portfolio  will  not  use  these  transactions  for  leveraging   purposes  and,
accordingly, will segregate cash or liquid securities 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  


                                      -4-
<PAGE>

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.

Illiquid and Restricted Securities
An  investment  may be  illiquid  because of the  absence  of an active  trading
market,  making  it  difficult  to  sell  promptly  at an  acceptable  price.  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, as amended. Each Portfolio may invest in restricted securities governed by
Rule 144A under the Securities  Act of 1933, as amended.  In adopting Rule 144A,
the  Securities and Exchange  Commission  (the "SEC")  specifically  stated that
restricted  securities  traded  under  Rule 144A may be  treated  as liquid  for
purposes  of  investment  limitations  if the board of  trustees  (or the fund's
adviser  acting  subject  to  the  board's  supervision)   determines  that  the
securities  are in  fact  liquid.  The  Board  of  Trustees  has  delegated  its
responsibility to Alger Management to determine the liquidity of each restricted
security  purchased  pursuant  to the Rule,  subject  to the Board of  Trustees'
oversight  and review.  Examples of factors  that will be taken into  account in
evaluating  the  liquidity  of a Rule 144A  security,  both with  respect to the
initial  purchase  and on an  ongoing  basis,  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).  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 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
In order to generate  income and to offset  expenses,  each  Portfolio  may lend
portfolio  securities with a value up to 331/3% of the Portfolio's  total assets
including collateral on such loans, less liabilities exclusive of the obligation
to  return   such   collateral,   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  or letters of credit 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 may invest up to 20% of the value of its total assets in foreign
securities (not including  American  Depositary  Receipts,  American  Depositary
Shares  or U.S.  dollar-denominated  securities  of  foreign  issuers).  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  among  nations.  Dividends  paid by foreign  issuers  may be subject 


                                      -5-
<PAGE>

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.  It  should  be noted  that  certain  of the risks
associated  with  foreign  securities  may  also  apply to  American  Depositary
Receipts and American Depositary Shares.

BORROWING (ALGER AMERICAN LEVERAGED ALLCAP PORTFOLIO)
Alger American Leveraged AllCap Portfolio may borrow money from banks and use it
to  purchase  additional  securities.  This  borrowing  is known as  leveraging.
Leveraging  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 (ALGER AMERICAN LEVERAGED
ALLCAP PORTFOLIO)
The  Portfolio  may buy and sell  (write)  exchange  listed  options in order to
obtain additional return or to hedge the value of its portfolio although,  as in
the past, it does not currently intend to rely on these strategies  extensively,
if at all.  Hedging  transactions  are  intended  to  reduce  the  risk of price
fluctuations. The Portfolio may write an option on a security only if the option
is  "covered".  Although  the  Portfolio  will  generally  not purchase or write
options that appear to lack 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.

A call  option on a security  is a contract  that gives the holder of the option
the right,  in return for a premium paid, to buy from the writer (seller) of the
call option 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 on a
security 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  written by the  Portfolio  on a  security  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) 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.  A put option written by the Portfolio is
"cov-


                                      -6-
<PAGE>

ered" if the Portfolio maintains cash or other high-grade short-term obligations
with a value equal to the exercise price in a segregated  account, 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 a closing purchase
or sale transaction can be effected when the Portfolio so desires.

The Portfolio would realize a profit from a closing  transaction if the price of
the transaction  were less than the premium  received from writing the option or
more than the premium paid to purchase the option; the Portfolio would realize a
loss from a closing  transaction if the price of the transaction  were 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.  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 a
particular  option 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 option. If the Portfolio,  as a covered call option writer, were
unable to effect a closing purchase  transaction in a secondary market, it would
not be able to sell the  underlying  security  until the  option  expired  or it
delivered the underlying security upon exercise or otherwise cover 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
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 would  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  might be  forced  to
liquidate portfolio securities to meet settlement obligations.

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

STOCK INDEX FUTURES AND OPTIONS ON STOCK
INDEX FUTURES (ALGER AMERICAN LEVERAGED
ALLCAP PORTFOLIO)
If the Portfolio utilizes these investments, it will do so only for hedging, not
speculative,  purposes. 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 


                                      -7-
<PAGE>

called for in the contract at a specified  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  would  purchase  and sell  futures
contracts  on the stock  index for which it could  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,  although it has not invested in
index futures in the past.

The risk of  imperfect  correlation  will  increase  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,  if it uses a hedging  strategy,  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  would 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 could be effected or that
there would be correlation between price movements in the options on stock index
futures and price movements in the Portfolio's securities which were the subject
of the hedge.  In addition,  the  Portfolio's  purchase of such options would be
based upon predictions as to anticipated market trends,  which could prove to be
inaccurate.

The Portfolio's  use, if any, 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, it at all, 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  market-to-market  value  of the  contract
fluctuates. The purchase of an option on stock index futures involves payment of
a premium  for the option  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.

OTHER INVESTMENTS
In addition to the  securities  and  investment  techniques  listed above,  each
Portfolio  may  invest in bank and  thrift  obligations,  obligations  issued or
guaranteed  by the U.S.  Government  or by its  agencies  or  instrumentalities,
foreign bank  obligations and obligations of foreign 


                                      -8-
<PAGE>

branches of domestic banks,  variable rate master demand notes,  firm commitment
agreements  and  "when-issued"   purchases;  and  the  Alger  American  Balanced
Portfolio may engage in reverse repurchase agreements.

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
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 5% of the value of a  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  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) the Portfolio may borrow for temporary or
emergency (but not leveraging,  except for the Alger American  Leveraged  AllCap
Portfolio)  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
American  Balanced  Portfolio may engage in transactions  in reverse  repurchase
agreements;  and (c) the Alger American  Leveraged  AllCap  Portfolio may borrow
from banks for  investment  purposes  as set forth in the  Prospectus.  Whenever
borrowings  described  in (a)  exceed 5% of the value of the  Portfolio's  total
assets,  the Portfolio  will not make any  additional  investments.  Immediately
after any borrowing, including reverse repurchase agreements and mortgage-backed
rolls,  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 conjunction 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. Underwriting the securities of other issuers, except insofar as the Portfolio

assets or offer of exchange.

9.  Purchasing any securities that would cause more than 25 percent of the value

violation of the restriction.  Additional  limitations  imposed by state law and
regulations may apply.

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.  


                                      -10-

To the extent consistent with applicable provisions of the Act and the rules and
exemptions  adopted  by  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.  Alger Management's fees under
its  agreements  with the  Portfolios are 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 year ended December 31,
1996, the Fund paid an aggregate of  approximately  $4,066,005 in commissions to
broker-dealers  in connection with portfolio  transactions,  of which $3,802,749
(94%) was paid to Alger Inc. During the fiscal year ended December 31, 1996, 92%
of the aggregate dollar amount of the Fund's transactions  involving the payment
of brokerage commissions were effected through Alger Inc. During the fiscal year
ended December 31, 1997, the Fund paid an aggregate of approximately  $7,837,883
in commissions to  broker-dealers  in connection with portfolio  transactions of
which  $7,712,699  (98.%)  was paid to Alger Inc.  During the fiscal  year ended
December 31, 1997, 98% of the aggregate dollar amount of the Fund's transactions
involving the payment of brokerage  commissions were effected through Alger Inc.
During the fiscal year ended  December 31,  1998,  the Fund paid an aggregate of
approximately  $7,974,970 in commissions to  broker-dealers  in connection  with
portfolio transactions,  of which $7,917,064 (99%) was paid to Alger Inc. During
the fiscal year ended December 31, 1998,  97% of the aggregate  dollar amount of
the Fund's  transactions  involving  the payment of brokerage  commissions  were
effected through Alger Inc. 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 includes securities traded in
the over-the-counter markets, money market investments and most debt securities.

PORTFOLIO TURNOVER
The portfolio  turnover  rates of all of the  Portfolios  except Alger  American
Small  Capitalization  Portfolio were significantly higher in 1997 than in 1996.
(See "Financial  Highlights" in the  Prospectus.)  This was due primarily to the
fact that the  markets  for the  types of  securities  in which  the  Portfolios
typically invest were  substantially  more volatile,  resulting in more frequent
trading by the  Portfolios,  in 1997 than in 1996; the contrast  between the two
years was heightened by the fact that turnover rates for 1996 tended to be lower
on average than in other recent years.

NET ASSET VALUE
The  Prospectus  discusses  the  time at  which  the  net  asset  values  of the
Portfolios are determined  for purposes of sales and  redemptions.  The New York
Stock  Exchange (the "NYSE") is currently  open on each Monday  through  Friday,
except (i) January 1st, Dr. Martin Luther King,  Jr. Day,  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.


                                      -11-
<PAGE>

The  assets  of the  Portfolios  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 money market  instruments with maturities of 60 days or less 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.

PURCHASES AND REDEMPTIONS
Shares  of the  Portfolios  are  offered  by the Fund on a  continuous  basis to
separate accounts of certain life insurance companies  ("Participating Insurance
Companies")  and to Plans.  Shares are  distributed  by Alger Inc. as  principal
underwriter for the Fund pursuant to a distribution agreement (the "Distribution
Agreement")  which  provides  that Alger Inc.  accepts  orders for shares at net
asset value and no sales commission or load is charged. 

The separate accounts of the Participating  Insurance  Companies place orders to
purchase and redeem shares of each Portfolio  based on, among other things,  the
amount of  premium  payments  to be  invested  and the amount of  surrender  and
transfer  requests (as defined in the  prospectuses  describing the VA contracts
and VLI policies issued by the Participating Insurance Companies) to be effected
on that day pursuant to VA contracts  and VLI policies.  Plan trustees  purchase
and redeem Portfolio shares.  Plan participants cannot contact the Fund directly
to purchase  shares of the Portfolios but may invest in shares of the Portfolios
only through their Plan. The Fund does not assess any fees, either when it sells
or when it redeems its shares.  Surrender  charges,  mortality  and expense risk
frees and other  charges may be assessed by  Participating  Insurance  Companies
under the VA  contracts or VLI  policies.  These fees should be described in the
Participating  Insurance  Companies'  prospectuses.  Any charges assessed by the
Plans should be described in the Plan  documents.  Participants  should  contact
their Plan sponsor for  information  concerning  the  appropriate  procedure for
investing in the Fund. 

The Fund may suspend the right of  redemption of shares of any Portfolio and may
postpone payment for any period:  (i) during which the NYSE is closed other than
customary  weekend and holiday  closings or during which  trading on the NYSE is
restricted;  (ii) when the SEC determines that a state of emergency exists which
may make payment or transfer not reasonably practicable; (iii) as the SEC may by
order permit for the protection of the  shareholders of the Fund; or (iv) at any
other time when the Fund may, under  applicable  laws and  regulations,  suspend
payment on the redemption of its shares.

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 a 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.

PARTICIPATING INSURANCE
COMPANIES AND PLANS

The Fund is intended to be a funding  vehicle for VA contracts  and VLI policies
to be offered by the  separate  accounts  of certain  life  insurance  companies
("Participating  Insurance Companies") and Plans. Individuals cannot invest in a
Portfolio  directly  but may do so only through a VA contract or VLI policy or a
Plan. The Fund currently does not foresee any disadvantages to the holders of VA
contracts  and VLI  policies  arising  from the fact that the  interests  of the
holders of VA  contracts  and VLI policies  may differ,  that the  Participating
Insurance  Companies may not be affiliated  with each other or that the Fund may
offer its shares to Plans. Nevertheless, the Fund's Board of Trustees intends to
monitor events in order to identify any material irreconcilable  conflicts which
may possibly arise due to differences of tax treatment or other  considerations,
and to  determine  what  action,  if any,  should be taken in  response  to such
conflicts. If such a conflict were to occur, one or more Participating Insurance
Company separate accounts or Plans might withdraw its investment in a Portfolio,
which may cause the Portfolio to sell  portfolio  securities at  disadvantageous
prices and orderly  portfolio  management  could be disrupted  to the  potential
detriment of the VA contract and VLI policy holders or Plan Participants. The VA
contracts and VLI policies are described in the separate  prospectuses issued by
the Participating  Insurance Companies,  and the Plans are described in the Plan
documents   made   available  by  the  Plan   sponsors.   The  Fund  assumes  no
responsibility for such prospectuses or plan documents.

the Fund.  Each  independent  Trustee is paid a fee of $1500 for each meeting he
attends, to a maximum of $6,000. The Fund did not offer its Trustees any pension
or  retirement  benefits  during or prior to the fiscal year ended  December 31,
1998. The following table provides  compensation  amounts paid to  Disinterested
Trustees of the Fund for the fiscal year ended December 31, 1998. Mr. White, now
a Disinterested Trustee, was not a Trustee of the Fund during that period.

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 is responsible for the overall administration of the Fund, subject to
the  supervision of the Board of Trustees.  It pays the salaries of all officers
who are  employed by both it and the Fund.  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 the Fund's distributor,  Alger Inc., an
affiliate  of Alger  Management,  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 SEC. 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  value,  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.

During the fiscal years ended December 31, 1996, 1997, and 1998 Alger Management
earned  under the  terms of the  Management  Agreements  $92,934,  $217,844  and
$365,820,   respectively,  in  respect  of  Alger  American  Income  and  Growth
Portfolio; $10,617,051,  $12,582,027 and $8,665,222, respectively, in respect of
Alger  American  Small  Capitalization  Portfolio;  $5,604,710,  $8,988,054  and
$10,304,264,  respectively,  in  respect  of Alger  American  Growth  Portfolio;
$55,775,  $103,223  and  $154,672,  respectively,  in respect of Alger  American
Balanced Portfolio; and $2,330,374, $3,536,454 and $4,156,932,  respectively, in
respect of Alger American MidCap Growth Portfolio; earned $177,612, $399,269 and
$567,333, respectively, in respect of Alger American Leveraged AllCap Portfolio.

From time to time Alger  Management or its affiliates  may compensate  insurance
companies or their  affiliates whose customers hold shares of the Portfolios for
providing  a  variety  of  record-keeping,   administrative,   marketing  and/or
shareholder support services. This compensation,  which may be paid at a rate of
up to .50% of the net asset  value of shares  held by those  customers,  will be
paid from  Alger  Management's  or its  affiliates'  resources  and not from the
assets of the Fund.

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.

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
generally must preclear all personal  securities  transactions  prior to trading
and are subject to certain  prohibitions on personal trading. You can get a copy

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

EXPENSES

Each Portfolio pays expenses related to its daily operations, such as management
fees,  brokerage fees,  custodian fees, Trustees' fees, transfer agency fees and
legal  and  auditing  costs.  Alger  Management  has  agreed  to  reimburse  the
Portfolios to the extent that the annual operating expenses (excluding interest,
taxes, fees for brokerage services and extraordinary expenses) of Alger American
Balanced  Portfolio or Alger American Income and Growth  Portfolio exceed 1.25%,
or such  expenses  of  Alger  American  Small  Capitalization  Portfolio,  Alger
American  Growth  Portfolio,  Alger American MidCap Growth  Portfolio,  or Alger
American  Leveraged  AllCap  Portfolio  exceed  1.50%,  of the average daily net
assets  of the  applicable  Portfolio  for any  fiscal  year.  Any such  expense
reimbursements  will be  estimated  and  reconciled  daily and paid on a monthly
basis. In addition, 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.

DIVIDENDS AND DISTRIBUTIONS

Each  Portfolio  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 at net asset value on the payment date for each shareholder's account
in additional shares of the Portfolio that paid the dividend or distribution or,
in the  case  of VA  contracts  and  VLI  policies,  will be paid in cash at the
election of the Participating Insurance Company. Any dividends of the Portfolios
will be declared and paid annually.  Distributions  of any net realized  capital
gains earned by a Portfolio usually will be made annually after the close of the
fiscal year in which the gains are earned. Participating Insurance Companies and
Plans  will be  informed  about  the  amount  and  character  of  dividends  and
distributions from the relevant Portfolio for federal income tax purposes.

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 will be treated as a separate  taxpayer with the result that, for
federal income tax purposes,  the amounts of net  investment  income and capital
gains earned will be  determined on a  Portfolio-by-Portfolio  (rather than on a
Fund-wide) basis.

Each  Portfolio  has been  structured  so that each  qualifies  separately  as a
regulated  investment company within the meaning of the Internal Revenue Code of
1986,  as amended (the "Code").  To so qualify,  a Portfolio  must,  among other
things:  (a) derive at least 90% of its gross  income in each  taxable year from
dividends,  interest,  payments with respect to securities  loans and gains from
the sale or other  disposition  of stock  or  securities;  and (b) meet  certain
quarterly diversification tests.

As a regulated  investment  company,  a Portfolio will not be subject to federal
income tax on its net investment  income and net realized  capital gains that it
distributes  to its  shareholders,  provided  that  at  least  90%  of  its  net
investment income and net realized short-term capital gains for the taxable year
is  distributed.  All net  investment  income  and net  realized  capital  gains
distributed by a Portfolio will be reinvested automatically in additional shares
of the Portfolio or paid in cash.  Amounts  reinvested in additional shares will
be considered to have been distributed to shareholders.

The  Fund  distributes  shares  in the  Portfolios  to  Participating  Insurance
Companies which will hold those 


                                      -16-
<PAGE>

shares,  directly or  indirectly,  in a "segregated  asset  account"  within the
meaning of the Code. To qualify as a segregated asset account,  the Portfolio in
which such an account holds shares must meet the diversification requirements of
Section 817(h) of the Code and the regulations promulgated thereunder.

The Fund has  undertaken  to meet the  diversification  requirements  of Section
817(h) of the Code.  This  undertaking  may limit the  ability  of a  particular
Portfolio to make certain otherwise permitted investments.

Income on assets of a segregated asset account will not be taxable  currently to
VA contracts or VLI policy  holders if that account has met the  diversification
requirements under Section 817(h) of the Code. In the event an account is not so
qualified, all VA contracts or VLI policies allocating any amount of premiums to
such account will not qualify as "annuity  contracts"  or "life  insurance"  for
federal income tax purposes. In that event, the holder of the VA contract or VLI
policy  would be taxed as though he owned a  proportionate  amount of the assets
held by such account  during and after all periods for which the account  failed
to be qualified.

Generally,  distributions  from a Plan will be taxable as ordinary income at the
rate  applicable  to the  participant  at the time of  distribution.  In certain
cases,  distributions  made to a  participant  from a Plan  prior to the date on
which the participant reaches age 59 1/2 are subject to a penalty tax equivalent
to 10% of the amount so  distributed,  in  addition to the  ordinary  income tax
payable on such amount for the year in which it is distributed.

CUSTODIAN
Custodial Trust Company, 101 Carnegie Center,  Princeton, New Jersey 08540-6231,
serves as custodian for the Fund pursuant to a custodian  agreement  under which
it holds the Portfolios' assets.

TRANSFER AGENT
Alger Shareholder Services,  Inc., 30 Montgomery Street, Jersey City, New Jersey
07302,  serves as  transfer  agent for the Fund  pursuant  to a transfer  agency
agreement.  Under the transfer agency agreement Alger Shareholder Services, Inc.
processes  purchases and redemptions of shares of the Portfolios,  maintains the
shareholder account records for each Portfolio,  handles certain  communications
between   shareholders   and  the  Fund  and   distributes   any  dividends  and
distributions payable by the Fund.

CERTAIN SHAREHOLDERS
Set forth below is certain information regarding significant shareholders of the
Portfolios.  At February 1, 1999,  Ameritas Variable Life Insurance Co. Separate
Account VA-2 Variable  Annuity owned  beneficially  or of record 48.97% of Alger
American  Income and Growth  Portfolio  and  64.44% of Alger  American  Balanced
Portfolio.  On the same date,  American  Skandia Life  Assurance  Company  owned
beneficially  or  of  record  57.01%  of  Alger  American  Small  Capitalization
Portfolio,  56.11%  of Alger  American  Growth  Portfolio  and  77.52%  of Alger
American  MidCap Growth  Portfolio.  The  shareholders  identified  above may be
deemed  to  control  the  specified  Portfolios,  which  may have the  effect of
proportionately  diminishing  the voting  power of other  shareholders  of these
Portfolios.

The following table contains information  regarding persons known by the Fund to
own  beneficially  or of record 5% or more of the shares of any  Portfolio.  All
holdings are expressed as a percentage of a Portfolio's outstanding shares as of
February 1, 1999 and record and beneficial holdings are in each instance denoted
as follows: record/beneficial.

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  April 6,  1988  (the  "Trust  Agreement").  Alger  American  Small
Capitalization  Portfolio,  Alger American  Income and Growth  Portfolio,  Alger
American Growth Portfolio, Alger American Balanced Portfolio (formerly the Alger
American Fixed Income  Portfolio),  Alger American  MidCap Growth  Portfolio and
Alger American Leveraged AllCap Portfolio commenced  operations on September 21,
1988,  November 15, 1988,  January 9, 1989,  September 5, 1989, May 3, 1993, and
January 25, 1995, respectively. The Fund offers an unlimited number of shares of
six  series,  representing  the shares of the  Portfolios.  The Fund's  Board of
Trustees may establish  additional  Portfolios at any time.  The word "Alger" in
the Fund's name has been adopted pursuant to a provision  contained in the Trust
Agreement. Under that provision, Alger Associates, Inc. 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.

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.   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.

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 Fund's Declaration of Trust.  Shareholders of one Portfolio may
vote only on matters that affect that Portfolio.

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.

Under  normal  circumstances,  other  than the shares  issued to Alger  Inc.  in
connection  with its  creation and initial  capitalization,  the Fund intends to
distribute  shares of the Portfolios only to Participating  Insurance  Companies
and Plans,  so that only  Participating  Insurance  Companies and their separate
accounts and Plans will be considered  shareholders of the Portfolios.  Although
the Participating  Insurance Companies and their separate accounts and the Plans
are the shareholders or investors,  the Participating  Insurance  Companies will
pass through  voting  rights to their VA contract and VLI policy  holders.  Plan
sponsors  may or may not  pass  through  voting  rights  to  Plan  participants,
depending on the terms of the Plan's  governing  documents.  For a discussion of
voting  rights   please  refer  to  the   Participating   Insurance   Companies'
prospectuses or the Plan documents.

DETERMINATION OF PERFORMANCE

Each Portfolio may include quotations of its "total return" in advertisements or
reports to shareholders or prospective investors.  Total return figures show the


                                      -19-
<PAGE>

aggregate or average  percentage change in value of an investment in a Portfolio
from the  beginning  date of the  measuring  period to the end of the  measuring
period. These figures reflect changes in the price of the Portfolio's shares and
assume that any income dividends and/or capital gains  distributions made by the
Portfolio during the period were reinvested in shares of the Portfolio.  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 Portfolio's operations,  or on
a year-by-year  basis) and may utilize dollar cost averaging.  The Portfolio may
use  "aggregate"  total return  figures for various  periods,  representing  the
cumulative  change in value of an  investment  in the Portfolio for the specific
period  (again  reflecting   changes  in  Portfolio  share  price  and  assuming
reinvestment  of dividends  and  distributions)  as well as "actual  annual" and
"annualized"  total  return  figures.  Total  returns  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
Portfolio will vary based on changes in market  conditions.  In addition,  since
the  deduction  of a  Portfolio's  expenses is reflected in the total return and
yield  figures,  "total return" and "yield" will also vary based on the level of
the Portfolio's expenses.

The  "total  return"  and  "yield"  as to each of the  Portfolios  are  computed
according  to formulas  prescribed  by the SEC.  These  performance  figures are
calculated in the following manner:

A. Total  Return--a  Portfolio's  average  annual total return  described in the
rospectus 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  Portfolios  for the periods  indicated
were as follows:

                                                                     PERIOD

IN GENERAL

Current  performance  information  for the Portfolios may be obtained by calling
the Fund at (800)  992-3863.  All  performance  figures are based on  historical
earnings.  A  Portfolio's  quoted  performance  may not be  indicative of future
performance.  A  Portfolio's  performance  will depend upon  factors such as the
Portfolio's  expenses and the types and  maturities of  instruments  held by the
Portfolio.  In addition, the actual return to a holder of a VA contract or a VLI
policy  will  be  affected  by  charges  imposed  by the  separate  accounts  of
Partici-


                                      -20-

pating Insurance Companies or, in the case of Plan participants,  by any charges
imposed under the Plan.

From time to time,  advertisements  or reports to  shareholders  may compare the
yield or  performance  of a  Portfolio  with that of other  mutual  funds with a
similar investment  objective.  The performance of the Portfolios,  for example,
might be compared with rankings  prepared by Lipper  Analytical  Services  Inc.,
which is a widely recognized,  independent service that monitors the performance
of mutual funds, as well as with various unmanaged indexes,  such as the S&P 500
Index,  the Russell 2000 Growth Index,  the S&P SmallCap 600 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.

THE ALGER AMERICAN FUND
NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 1998
================================================================================

NOTE 1--GENERAL:

The Alger  American  Fund (the  "Fund") is a  diversified,  open-end  registered
investment  company  organized  as a  business  trust  under  the  laws  of  the
Commonwealth of  Massachusetts.  The Fund operates as a series company currently
issuing six series of shares of beneficial interest:  American Growth Portfolio,
American Small Capitalization  Portfolio,  American Income and Growth Portfolio,
American  Balanced  Portfolio,  American  MidCap  Growth  Portfolio and American
Leveraged AllCap Portfolio (collectively the "Portfolios").  The American Growth
Portfolio,  American  Small  Capitalization  Portfolio,  American  MidCap Growth
Portfolio and American  Leveraged  AllCap  Portfolio  invest primarily in equity
securities   and  each  has  an  investment   objective  of  long-term   capital
appreciation.  The American  Income and Growth  Portfolio's  primary  investment
objective is to provide a high level of dividend  income by investing  primarily
in  dividend-paying  equity  securities;  capital  appreciation  is a  secondary
objective.  The American Balanced Portfolio's  investment objectives are current
income and  long-term  capital  appreciation  which it seeks to achieve  through
investing in equity and fixed income  securities.  Shares of the  Portfolios are
available and are being marketed  exclusively  as a pooled  funding  vehicle for
qualified retirement plans and for life insurance companies writing all types of
variable annuity contracts and variable life insurance policies.


NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

(a) INVESTMENT  VALUATION:  Investments of the Portfolios are valued on each day
the New  York  Stock  Exchange  ("NYSE")  is open as of the  close  of the  NYSE
(normally 4:00 p.m. Eastern time). Listed and unlisted securities for which such
information  is regularly  reported are valued at the last reported  sales price
or, in the absence of reported  sales, at the mean between the bid and the 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.

Securities  for which market  quotations  are not readily  available  are valued
according to procedures  established  by the Board of Trustees to determine fair
value in good faith.

Securities  having a  remaining  maturity  of sixty  days or less are  valued at
amortized cost which approximates market value.

(b) SECURITY  TRANSACTIONS  AND INVESTMENT  INCOME:  Security  transactions  are
recorded on a trade date basis.  Resulting  receivables and payables are carried
at amounts which approximate fair value. Realized gains and losses from security
transactions  are  recorded on the  identified  cost basis.  Dividend  income is
recognized  on the  ex-dividend  date and interest  income is  recognized on the
accrual basis.

(c) REPURCHASE AGREEMENTS:  The Portfolios enter into repurchase agreements with
approved  institutions,   primarily  U.S.  Government  securities  dealers.  The
repurchase agreements are collateralized by U.S. Government securities which are
verified by the investment manager as being either received and held in physical
possession  by the  custodian  or as having been  received by such  custodian in
book-entry form through the Federal Reserve  book-entry  system.  The investment
manager  monitors  the  value  of the  collateral  at the  time  the  repurchase
agreement is entered into and on a daily basis during the term of the  agreement
to ensure that its value equals or exceeds the agreed-upon  repurchase  price to
be repaid to the Portfolio. Additional collateral is obtained when necessary.

(d) LENDING OF PORTFOLIO  SECURITIES:  The Portfolios  lend their  securities to
financial institutions,  including an affiliate of the custodian,  provided that
the market value of securities  loaned will not at any time exceed  one-third of
the  Portfolio's  total  assets,  as defined.  The  Portfolios  earn fees on the
securities  loaned  which are  included in interest  income in the  accompanying
Statements of Operations. In order to protect against the risk of failure by the
borrower to return the  securities  loaned or any delay in the  delivery of such
securities,  the investment  manager ensures that the loan is  collateralized by
cash, letters of credit or U.S. Government securities that are maintained at all
times in an amount equal to at least 100 percent of the current  market value of
the loaned securities.  At December 31, 1998, the value of securities loaned and
collateral received thereon were as follows:

                                     VALUE OF
                                    SECURITIES        VALUE OF
                                      LOANED         COLLATERAL
                                   ------------     ------------

shareholders are recorded by the Fund on the ex-dividend date.

Dividends from net investment income are declared and paid annually.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


TO THE SHAREHOLDERS AND
     BOARD OF TRUSTEES OF THE ALGER AMERICAN FUND

We have audited the  accompanying  statements of assets and  liabilities  of The
Alger American Fund (a Massachusetts  business trust  comprising,  respectively,
the  Alger  American  Growth  Portfolio,  Alger  American  Small  Capitalization
Portfolio,  Alger American Income and Growth Portfolio,  Alger American Balanced
Portfolio,  Alger American MidCap Growth Portfolio and Alger American  Leveraged
AllCap  Portfolio),  including the schedules of investments,  as of December 31,
1998, and the related  statements of operations and cash flows for the year then
ended,  the statements of changes in net assets for each of the two years in the
period then ended,  and the financial  highlights  for each of the five years in
the period then ended. These financial  statements and financial  highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements and financial  highlights.  Our procedures  included  confirmation of
securities owned as of December 31, 1998, by  correspondence  with the custodian
and brokers. An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material  respects,  the financial position of each
of the respective portfolios constituting The Alger American Fund as of December
31,  1998,  the  results  of their  operations  and cash flows for the year then
ended,  the  changes in their net assets for each of the two years in the period
then  ended,  and the  financial  highlights  for each of the five  years in the
period then ended, in conformity with generally accepted accounting principles.

APPENDIX

CORPORATE BOND RATINGS

    Bonds rated Aa by Moody's Investors Service,  Inc. ("Moody's") are judged by
Moody's 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 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.

    Bonds rated Ba by Moody's  are judged to have  speculative  elements;  their
future cannot be considered  as well assured.  Often the  protection of interest
and  principal  payments may be very  moderate and thereby not well  safeguarded
during  both  good  and  bad  times  in  the  future.  Uncertainty  of  position
characterizes  bonds in this class. Bonds which are rated B by Moody's generally
lack  characteristics  of a desirable  investment.  Assurance  of  interest  and
principal  payments or of  maintenance  of other terms of the contract  over any
period of time may be small.

    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 AA by Standard & Poor's Corporation ("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 A 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-rated that qualifies
for commercial  bank  investment.  Bonds rated BB and B by S&P are regarded,  on
balance,  as predominantly  speculative with respect to capacity to pay interest
and  repay  principal  in  accordance  with the terms of the  obligation.  These
ratings may be modified by the addition of a plus or minus sign to show relative
standing  within the major rating  categories.  Debt rated BB has less near-term
vulnerability to default than other speculative issues.  However, it faces major
ongoing  uncertainties  or exposure to adverse  business,  financial or economic
conditions  that could lead to inadequate  capacity to meet timely  interest and
principal payments. The BB rating category is also used for debt subordinated to
senior debt that is assigned an actual or implied BBB- rating.  Debt rated B has
a greater  vulnerability  to default  but  currently  has the  capacity  to meet
interest  payments and  principal  repayments.  Adverse  business,  financial or
economic  conditions  will likely impair capacity or willingness to pay interest
and repay principal. The B rating category is also used for debt subordinated to
senior debt that is assigned an actual or implied BB or BB- rating.  Bonds rated
AAA by  Fitch  Investors  Service,  Inc.  ("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 

                                      A-1

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-1 are judged by Duff and Phelps, Inc. ("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.

COMMERCIAL PAPER RATINGS

    Moody's  Commercial  Paper ratings are opinions of the ability of issuers to
repay  punctually  promissory  obligations  not having an  original  maturity in
excess of nine months. The rating Prime-1 is the highest commercial paper rating
assigned by Moody's.  Issuers rated Prime-1, or related supporting institutions,
are  considered  to  have  a  superior  capacity  for  repayment  of  short-term
promissory   obligations.   Issuers  rated   Prime-2,   or  related   supporting
institutions,  are  considered  to  have a  strong  capacity  for  repayment  of
short-term  promissory  obligations.  This will normally be evidenced by many of
the characteristics of issuers rated Prime-1,  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 liquidity is maintained.

    Commercial paper ratings of S&P are current assessments of the likelihood of
timely  payment of debts having  original  maturities  of no more than 365 days.
Commercial  paper rated A-1 by S&P indicates that the degree of safety regarding
timely payment is either overwhelming or very strong. Those issues determined to
possess  overwhelming  safety  characteristics  are denoted  A-1+.  Capacity for
timely payment on commercial paper rated A-2 is strong,  but the relative degree
of safety is not as high as for issues designated A-1.

    The rating Fitch-1  (Highest Grade) is the highest  commercial  paper rating
assigned  by Fitch.  Paper rated  Fitch-1 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.

Item 24.  Persons Controlled by or Under Common Control with Registrant

                    None.

Item 25.  Indemnification

     Under Section 8.4 of  Registrant's  Agreement and  Declaration of Trust any
past or present Trustee or officer of Registrant (including persons who serve at
Registrant's request as directors,  officers or trustees of another organization
in which  Registrant  has any interest as a  shareholder,  creditor or otherwise
[hereinafter  referred to as a "Covered  Person"]) is indemnified to the fullest
extent permitted by law against liability and all expenses  reasonably  incurred
by him in  connection  with any action,  suit or proceeding to which he may be a
party or  otherwise  involved  by reason  of his being or having  been a Covered
Person. This provision does not authorize indemnification when it is determined,
in the manner  specified in the Agreement and  Declaration  of Trust,  that such
Covered  Person has not acted in good faith in the  reasonable  belief  that his
actions were in or not opposed to the best  interests of  Registrant.  Moreover,
this provision does not authorize  indemnification when it is determined, in the
manner  specified in the Agreement and  Declaration of Trust,  that such Covered
Person would otherwise be liable to Registrant or its  shareholders by reason of
willful  misfeasance,  bad faith,  gross negligence or reckless disregard of his
duties.  Expenses may be paid by Registrant in advance of the final  disposition
of any action, suit or proceeding upon receipt of an undertaking by such Covered
Person to repay such  expenses to  Registrant in the event that it is ultimately
determined that indemnification of such expenses is not

                                      C-4


<PAGE>

authorized  under the  Agreement  and  Declaration  of Trust and  either (i) the
Covered  Person  provides  security for such  undertaking,  (ii)  Registrant  is
insured against losses from such advances or (iii) the disinterested Trustees or
independent legal counsel  determines,  in the manner specified in the Agreement
and  Declaration  of Trust,  that there is reason to believe the Covered  Person
will be found to be entitled to indemnification.

     Insofar as  indemnification  for liability arising under the Securities Act
of 1933 (the  "Securities  Act"),  may be permitted  to  Trustees,  officers and
controlling  persons of  Registrant  pursuant to the  foregoing  provisions,  or
otherwise, Registrant has been advised that in the opinion of the Securities and
Exchange Commission (the "SEC") such indemnification is against public policy as
expressed in the Securities Act and is, therefore,  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment by  Registrant  of expenses  incurred  or paid by a Trustee,  officer or
controlling person of Registrant in the successful  defense of any action,  suit
or  proceeding) is asserted by such Trustee,  officer or  controlling  person in
connection with the securities being registered,  Registrant will, unless in the
opinion of its counsel  the matter has been  settled by  controlling  precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of such issue.

Item 26.  Business and Other Connections of Investment Adviser

     Alger  Management,  which serves as investment  manager to  Registrant,  is
generally engaged in rendering investment advisory services to institutions and,
to a lesser extent, individuals. Alger Management presently serves as investment
adviser  to one  closed-end  investment  company  and to  three  other  open-end

     Re:  The Alger American Fund
          Amendment to Registration Statement on Form N1-A

Ladies and Gentlemen:

     You have requested our opinion as to certain matters of  Massachusetts  law
in connection  with the filing by The Alger  American Fund  (formerly "THE ALGER
VARIABLE INSURANCE PRODUCTS FUND"), a trust with transferable shares established
under Massachusetts law (the "TRUST"), of Post-Effective Amendment No. 16 to the
Trust's Registration Statement on Form N-1A (the "REGISTRATION STATEMENT") under
the Securities Act of 1933, as amended (the "Securities Act"),  Registration No.
33-21722,  and  Amendment  No.  18  to  its  Registration  Statement  under  the
Investment Company Act of 1940,  Registration No. 811-05550  (collectively,  the
"Amendment").

     We acted as  Massachusetts  counsel  to the  Trust in  connection  with the
execution and delivery of its  Declaration  of Trust filed with the Secretary of
the Commonwealth of  Massachusetts on May 6, 1988 (the "Original  Declaration"),
and the several  amendments  thereto  filed  January 18,  1989,  June 26,  1992,
October 6, 1993 and February 18, 1994 (the Original  Declaration  as so amended,
the  "Declaration"),  and the  authorization by the Trustees of the Trust of the
issuance and sale of shares of beneficial interest,  one mill ($.001) par value,
of the several series  authorized by the Declaration (the "Shares") which are to
be registered  pursuant to the Amendment.  In this connection,  we have examined
and are familiar with the  Declaration,  the Bylaws of the Trust, the Amendment,
substantially  in the form in which it is to be filed  with the  Securities  and
Exchange  Commission (the "SEC"), the forms of the Prospectus (the "Prospectus")
and  the  Statement  of  Additional  Information  (the  "SAI")  included  in the
Amendment,  certificates of officers of the Trust as to actions of the Trustees,
certificates  of  officers  of the  Trust and of  public  officials  as to other
matters of fact, and such questions of law and fact, as we have

<PAGE>

The Trustees of
  The Alger American Fund           -2-                      February 16, 1999


considered  necessary or  appropriate  for  purposes of the  opinions  expressed
herein.  We  have  assumed  the  genuineness  of  the  signatures  on,  and  the
authenticity  of,  all  documents  furnished  to us, and the  conformity  to the
originals of documents submitted to us as certified copies,  which facts we have
not independently verified.

     Based upon and subject to the foregoing,  we hereby advise you that, in our
opinion, under Massachusetts law:

1.   The Trust is validly  existing as a trust with  transferable  shares of the
     type commonly called a Massachusetts business trust.

2.   The Trust is authorized to issue an unlimited number of Shares;  the Shares
     have  been  duly and  validly  authorized  by all  requisite  action of the
     Trustees of the Trust,  and no action of the  shareholders  of the Trust is
     required in such connection.

3.   The Shares subject to the Registration  Statement,  when duly sold,  issued
     and paid for as contemplated by the Prospectus and the SAI, will be validly
     and legally issued, and fully paid and nonassessable by the Trust.
 
     With respect to the opinion  stated in paragraph 3 above,  we wish to point
out that the  shareholders  of a  Massachusetts  business  trust may under  some
circumstances  be subject to  assessment at the instance of creditors to pay the
obligations of such trust in the event that its assets are  insufficient for the
purpose.

     This letter  expresses our opinions as to the provisions of the Declaration
and the laws of The  Commonwealth of  Massachusetts  applying to business trusts
generally,  but does not  extend  to the  Massachusetts  Securities  Act,  or to
federal securities or other laws.

     We hereby  consent to the  reference  to us in the  Prospectus,  and to the
filing of this opinion with the SEC as an exhibit to the Registration Statement.
In giving such consent, we do not thereby admit that we come within the category
of persons whose consent is required  under Section 7 of the  Securities  Act of
1933, as amended.

                                                Very truly yours,
