1    INVESTMENT OBJECTIVE
The  investment  objective of the Growth & Income Series is long-term  growth of
capital and income without excessive  fluctuations in market value. The Growth &
Income Series normally invests in common stocks of large,  seasoned companies in
sound  financial  condition  which  are  expected  to show  above-average  price
appreciation.  The investment objective of the International Series is long-term
capital appreciation. The production of any current income is incidental to this
objective and the  International  Series also may invest in securities  which do
not produce any income.  The International  Series normally invests primarily in
equity securities of non-U.S. issuers.

        Class B shares(3)          $21       $65       $111      $220

        Class C shares             $21       $66       $113      $243

(1)  Although  neither  Series,  with  respect  to Class B and  Class C  shares,
     charges a front-end sales charge,  investors should be aware that long-term
     shareholders  may pay, under the Rule 12b-1 Plan  applicable to Class B and
     Class  C  shares  (both  of  which  pay  annual  0.25%  service  and  0.75%
     distribution  fees),  more  than the  economic  equivalent  of the  maximum
     front-end  sales  charge as  permitted  by  certain  rules of the  National
     Association of Securities Dealers,  Inc. Likewise,  with respect to Class A
     shares,  investors  should be aware that,  over the long term, such maximum
     may be  exceeded  due to the Rule 12b-1 Plan  applicable  to Class A shares
     which permits each Series to pay up to 0.50% in total annual fees, half for
     service and the other half for distribution.

(2)  Sales "load" is referred to as sales "charge" and "deferred  sales load" is
     referred to as  "contingent  deferred  sales charge" (or "CDSC") and "12b-1
     fees"  which  consist  of a  "service  fee"  and a  "distribution  fee" are
     referred to by either or both of these terms where appropriate with respect
     to Class A, Class B and Class C shares throughout this Prospectus.

(3)  Class B shares will  automatically  convert to Class A shares on the eighth
     anniversary of the purchase of Class B shares.

(4)  The annual  operating  expenses  for the Growth & Income  Series  have been
     restated  from  October 31, 1996 fiscal year  amounts,  to reflect  current
     fees. The annual operating expenses for the International  Series are based
     on estimated expenses for the current fiscal year.

The  foregoing  is provided  to give  investors  a better  understanding  of the
expenses that are incurred by an investment in each Series.

4    HOW WE INVEST

The Growth & Income Series.  The Series is intended for long-term  investors who
purchase and redeem shares to meet their own financial  requirements rather than
to take  advantage of price  fluctuations.  The needs of such  investors will be
best served by an investment  whose growth is  characterized by low fluctuations
in market value.  For this reason,  the Series tries to keep its assets invested
in securities  which are selling at reasonable  prices in relation to value and,
thus, is willing to forgo some  opportunities for gains when, in the judgment of
Fund management,  they carry excessive risk. Fund management tries to anticipate
major  changes in the economy and select  stocks which it believes  will benefit
most from these changes.  The Growth & Income Series normally  invests in common
stocks (including securities  convertible into common stocks) of large, seasoned
companies which are expected to show above-average growth in value and which are
in sound financial condition. Although the prices of common stocks fluctuate and
their dividends vary, historically,  common stocks have appreciated in value and
their  dividends have increased when the companies they represent have prospered
and grown.  The Growth & Income Series is constantly  balancing the  opportunity
for profit  against  the risk of loss.  In the past,  very few  industries  have
continuously  provided  the  best  investment  opportunities.   Fund  management
believes it is important to take a flexible approach and adjust the portfolio to
reflect changes in the opportunities for sound investments relative to the risks
assumed;  therefore,  it sells  securities  that it judges to be overpriced  and
reinvests  the  proceeds  in other  securities  which it believes  offer  better
values.

<PAGE>


The Series may invest up to 10% of its net assets (at the time of investment) in
each of the following:  (a) covered call options traded on a national securities
exchange for  portfolio  securities  and (b) foreign  securities.  These foreign
securities  will be the  kind  described  in  this  Prospectus  for the  Series'
domestic  investment.  It is the present intention of Fund management that these
securities be primarily traded in the United Kingdom, Western Europe, Australia,
Canada,  the Far East,  Latin America,  and other developed  countries as may be
determined  from time to time.  The Series also may invest in straight bonds and
other debt  securities,  including  lower  rated,  high-yield  bonds,  sometimes
referred to as "junk bonds" with a limit of 5% of its net assets (at the time of
investment) in such lower rated (BB/Ba or lower),  high-yield  bonds. The Series
does not purchase securities for trading purposes.  To create reserve purchasing
power and also for  temporary  defensive  purposes,  it may invest in short-term
debt and other high-quality, fixed-income securities.

Risk Factors -- Growth & Income Series

High-Yield  Bonds. The Series may invest up to 5% of its net assets (at the time
of investment),  in lower rated bonds for their higher yields.  In general,  the
market for lower rated bonds is more  limited  than that for higher  rated bonds
and, therefore,  may be less liquid. The market prices of such lower rated bonds
may fluctuate  more than those of higher rated bonds,  particularly  in times of
economic  change and  stress.  In  addition,  because the market for lower rated
corporate debt  securities has  experienced  wide  fluctuations in the values of
certain  of these  securities,  past  experience  may not  provide  an  accurate
indication  of the future  performance  of that  market or of the  frequency  of
default,  especially  during  periods of recession.  Objective  pricing data for
lower rated bonds may be more limited and  valuation of such  securities  may be
more  difficult  and require  greater  reliance  upon  judgment when compared to
higher rated bonds.

While the market for lower rated bonds may be less  sensitive  to  interest-rate
changes than that for higher rated bonds, the market prices of these lower rated
bonds  structured as zero coupon or pay-in-kind  securities may be affected to a
greater extent by such interest-rate  changes and thus may be more volatile than
prices of lower rated  securities  periodically  paying  interest in cash.  When
compared to higher rated bonds,  lower rated bonds that include redemption prior
to maturity or call  provisions  may be more  susceptible  to  refunding  during
periods of falling  interest  rates,  requiring  replacement  by lower  yielding
securities.

Since the risk of default  generally  is higher  among  lower rated  bonds,  the
research and analysis of Lord Abbett are  especially  important in the selection
of such bonds which, if rated BB/Ba or lower, are often described as "high-yield
bonds" because of their generally  higher yields and referred to as "junk bonds"
because  of  their  greater  risks.  In  selecting  lower  rated  bonds  for our
investment, Lord Abbett does not rely upon ratings which, in any event, evaluate
only the safety of  principal  and  interest,  not market  value risk and which,
furthermore, may not accurately reflect an issuer's current financial condition.
There are no minimum rating criteria for investments in these bonds and some may
default as to principal and/or interest  payments  subsequent to their purchase.
Through  portfolio  diversification,  credit  analysis and  attention to current
developments  and trends in interest rates and economic  conditions,  investment
risk can be reduced, although there is no assurance that losses will not occur.

The International  Series.  Portfolio  investments for the International  Series
will be made in equity securities of companies domiciled in developed countries,
but  investments  also may be made in the  securities of companies  domiciled in
developing  countries.  Equity  securities  include common and preferred stocks,
convertible securities, and rights and warrants to purchase common stocks. Under
normal  circumstances,  at least 80% of the total  assets of the Series  will be
invested in such equity  securities of companies which are domiciled in at least
three  different  countries  outside  the United  States.  The Series  currently
intends to  diversify  investments  among  countries  to reduce  currency  risk.
Although the Series will typically hold a number of diversified  securities,  it
does  entail  above-average  investment  risk in  comparison  to the U.S.  stock
market.


<PAGE>


Although  the  International  Series  intends  to  invest  primarily  in  equity
securities  of  companies  with  market  capitalization  of less than $1 billion
listed on stock  exchanges,  it may also  invest in  equity  securities  of such
companies  traded  in  over-the-counter  markets,  as well as large  and  middle
capitalization securities.  Small capitalization securities involve greater risk
and the markets for such  securities  may be more  volatile and less liquid than
those of larger securities.  Securities of companies in developing countries may
pose liquidity  risks. For a description of special  considerations  and certain
risks associated with investments in foreign issuers,  see "Risk Factors -- Both
Series"  below.  The Series may  temporarily  reduce  its  equity  holdings  for
defensive  purposes  in  response  to adverse  market  conditions  and invest in
domestic,  Eurodollar  and foreign  short-term  money  market  instruments.  See
"Investment Objectives and Policies" in the Statement of Additional Information.

Although  the  International  Series  will not  invest  for  short-term  trading
purposes,  investment securities may be sold from time to time without regard to
the  length of time  they have been  held.  It is  anticipated  that the  annual
turnover rate of the Series will not exceed 100% under normal circumstances.

Any  remaining  assets of the  Series not  invested  as  described  above may be
invested in certain  securities or obligations  as set forth in "Other  Policies
Common to Both Series" below.

Foreign  Currency  Hedging  Techniques.  The  International  Series may  utilize
various foreign currency hedging  techniques  described below. A forward foreign
currency  contract  involves an obligation to purchase or sell a specific amount
of a currency at a set price on a future date. The Series may enter into forward
foreign  currency  contracts  (but not in excess of the  amount  the  Series has
invested in non-U.S. dollar-denominated securities at the time any such contract
is entered into) in primarily two  circumstances.  First, when the Series enters
into a contract for the purchase or sale of a security  denominated in a foreign
currency,  the  Series  may  desire  to "lock in" the U.S.  dollar  price of the
security.  By entering  into a forward  contract for the purchase or sale of the
amount of foreign currency involved in the underlying security transaction,  the
Series will be able to protect against a possible loss resulting from an adverse
change in the  relationship  between  the U.S.  dollar and the  subject  foreign
currency  during the period between the date of purchase or sale and the date of
settlement.

Second,  when Fund management believes that the currency of a particular foreign
country may suffer a decline against the U.S. dollar,  the International  Series
may enter  into a  forward  contract  to sell the  amount  of  foreign  currency
approximating  the  value  of some or all of the  Series'  portfolio  securities
denominated in such foreign currency or, in the alternative,  the Series may use
a  cross-currency-hedging  technique  whereby  it  enters  into  such a  forward
contract to sell  another  currency  (obtained  in exchange  for the currency in
which the portfolio  securities  are  denominated  if such  securities are sold)
which  it  expects  to  decline  in a  similar  manner  but  which  has a  lower
transaction cost.  Precise matching of the forward contract and the value of the
securities  involved will  generally  not be possible  since the future value of
such securities  denominated in foreign  currencies will change as a consequence
of  market  movements  in the  value of those  securities  between  the date the
forward contract is entered into and the date the contract  matures.  The Series
intends to enter into such  forward  contracts  under this  second  circumstance
periodically.

The Series also may  purchase  foreign  currency  put options and write  foreign
currency call options on U.S. exchanges or U.S.  over-the-counter markets. A put
option gives the Series, upon payment of a premium, the right to sell a currency
at the exercise  price until the  expiration  of the option and serves to insure
against  adverse  currency price  movements in the underlying  portfolio  assets
denominated  in that currency.  The premiums paid for such foreign  currency put
options  will not  exceed 5% of the net  assets of the  Series.  Exchange-listed
options  markets in the United  States  include  several major  currencies,  and
trading  may be thin and  illiquid.  A number of major  investment  firms  trade
unlisted  options  which are more  flexible  than  exchange-listed  options with
respect to strike price and maturity date. These unlisted options  generally are
available  on a  wider  range  of  currencies,  including  those  of most of the
developed countries mentioned above. Unlisted foreign-currency options generally
are less liquid than listed options and involve the credit risk  associated with
the individual issuer.

<PAGE>


Unlisted  options  together with other illiquid  securities may comprise no more
than 15% of the Series' net assets.
A foreign  currency call option written by the Series gives the purchaser,  upon
payment of a premium,  the right to  purchase  from the Series a currency at the
exercise price until the  expiration of the option.  The Series may write a call
option on a foreign currency only in conjunction with a purchase of a put option
on that  currency.  Such a strategy  is  designed to reduce the cost of downside
currency protection by limiting currency appreciation potential.  The face value
of such  writing or  cross-hedging  (described  above) may not exceed 90% of the
value of the  securities  denominated  in such  currency  (a) invested in by the
Series to cover such call writing or (b) to be crossed.  Limitations  imposed by
the Internal  Revenue Code on regulated  investment  companies  may restrict the
Series'  ability to engage in  transactions  in options,  forward  contracts and
cross hedges. The Series' custodian will segregate cash or permitted  securities
belonging  to the Series  with  respect to its assets  committed  to (a) writing
options,  (b) forward  foreign  currency  contracts and (c) cross hedges entered
into  by  the  Series.  If the  value  of the  securities  segregated  declines,
additional  cash or permitted  securities  will be added on a daily basis (i.e.,
marked  to  market),  so that the  segregated  amount  will not be less than the
amount of the Series' commitments with respect to such written options,  forward
foreign currency contracts and cross hedges.

Financial  Futures and Options  Thereon.  The  International  Series may deal in
financial futures  transactions with respect to the type of securities described
in this  Prospectus,  including  indices of such  securities and options on such
financial  futures  and  indices.  The Series  will not enter  into any  futures
contracts,  or options thereon,  if the aggregate market value of the securities
covered by futures  contracts plus options on such financial futures exceeds 50%
of the Series' total assets. Investment Funds. Some emerging countries have laws
and  regulations  that  currently  preclude  direct  foreign  investment  in the
securities  of their  companies.  However,  indirect  foreign  investment in the
securities of such countries is permitted  through  investment  funds which have
been specifically authorized.  The International Series may invest (normally not
more than 5% of the Series' total assets) in these  investment  funds subject to
the  provisions of the  Investment  Company Act of 1940,  as amended,  and other
applicable  restrictions  as discussed  herein or in the Statement of Additional
Information.  If the  Series  invests  in such  investment  funds,  the  Series'
shareholders will bear not only their proportionate share of the expenses of the
Series (including operating expenses and the fees of Lord Abbett), but also will
indirectly bear similar expenses of the underlying investment funds.

Depository Receipts.  The International Series may invest in American Depository
Receipts  ("ADRs"),  Global Depository  Receipts ("GDRs"),  European  Depository
Receipts ("EDRs") and other Depository Receipts (which, together with ADRs, GDRs
and EDRs, are hereinafter collectively referred to as "Depository Receipts"), to
the extent that such Depository Receipts become available.  ADRs are securities,
typically issued by a U.S. financial institution (a "depository"), that evidence
ownership  interests in a security or a pool of  securities  issued by a foreign
issuer (the "underlying issuer") and deposited with the depository.  ADRs may be
established by a depository  without  participation  by the  underlying  issuer.
GDRs,  EDRs and other  types of  Depository  Receipts  are  typically  issued by
foreign depositories, although they may also be issued by U.S. depositories, and
evidence  ownership  interests  in a security  or pool of  securities  issued by
either a  foreign  or a U.S.  corporation.  Generally,  Depository  Receipts  in
registered  form  are  designed  for  use  in the  U.S.  securities  market  and
Depository  Receipts in bearer form are designed for use in  securities  markets
outside the United  States.  The Series may invest in sponsored and  unsponsored
Depository  Receipts.  For  purposes  of the  International  Series'  investment
policies,  the Series'  investments in Depository  Receipts will be deemed to be
investments in the underlying securities.

Risk Factors -- Both Series

        Size. If either Series remains small,  there is risk that redemptions of
a Series'  shares may (a) cause  portfolio  securities of that Series to be sold
prematurely (at a loss or gain,  depending upon the circumstances) or (b) hamper
or prevent a contemplated portfolio security purchase by that Series.

Foreign  Investments.  Investment in either  Series  requires  consideration  of
certain  factors  that  are  not  normally   involved  in  investments  in  U.S.
securities.  Generally,  at least 80% of the assets of the International  Series
and  up to  10% of the  net  assets  of the  Growth  &  Income  Series  will  be
denominated or traded in foreign currencies.  Accordingly, a change in the value
of  any  foreign  currency  relative  to  the  U.S.  dollar  will  result  in  a
corresponding change in the U.S. dollar value of a Series' assets denominated or
traded in that currency. The performance of each Series will be measured in U.S.
dollars,  the base  currency  of each  Series.  Securities  markets  of  foreign
countries  in which a Series may invest  generally  are not  subject to the same
degree of  regulation  as the U.S.  markets  and may be more  volatile  and less
liquid  than the major  U.S.  markets.  Lack of  liquidity  may affect a Series'
ability to purchase or sell large blocks of securities  and thus obtain the best
price.  There  may be less  publicly-available  information  on  publicly-traded
companies, banks and governments in foreign countries than is generally the case
for such entities in the United States. The lack of uniform accounting standards
and practices  among  countries  impairs the validity of direct  comparisons  of
valuation  measures (such as price/earnings  ratios) for securities in different
countries.  In  addition,  a Series may incur  costs  associated  with  currency
hedging and the  conversion  of foreign  currency  into U.S.  dollars and may be
adversely  affected by  restrictions  on the  conversion  or transfer of foreign
currency.   Other  considerations  include  political  and  social  instability,
expropriation,  higher  transaction  costs and different  securities  settlement
practices. Settlement periods for foreign securities, which are sometimes longer
than those for securities of U.S. issuers, may affect portfolio liquidity. These
different settlement practices may cause missed purchasing  opportunities and/or
the loss of interest on money market and debt investments pending further equity
or long-term debt investments.  In addition, foreign securities held by a Series
may be traded on days that the Series do not value their  portfolio  securities,
such as Saturdays and customary U.S.  business  holidays,  and,  accordingly,  a
Series' net asset value may be significantly  affected on days when shareholders
do not have access to the Series.  Many of the emerging or developing  countries
may have higher and more rapidly  fluctuating  inflation  rates, a higher demand
for capital  investment,  a higher  dependence on export markets for their major
industries,  and a greater need to develop basic economic  infrastructures  than
more developed countries. Also, it may be more difficult to obtain a judgment in
a court outside the United States.

Other Policies Common to Both Series

Illiquid  Securities.  Each  Series  may  invest up to 15% of its net  assets in
illiquid securities.

Borrowing.  Each  Series may borrow  from  banks (as  defined in the  Investment
Company  Act of 1940,  as amended  (the  "Act")) in amounts up to 33 1/3% of its
total assets  (including the amount  borrowed).  Each Series may borrow up to an
additional 5% of its total assets for temporary purposes. Each Series may obtain
such  short-term  credit as may be necessary  for the clearance of purchases and
sales of portfolio securities.

Diversification.  Each Series  intends to meet the  diversification  rules under
Subchapter M of the Internal  Revenue  Code.  The Growth & Income Series met the
diversification  rules under  Subchapter M for its fiscal year ended October 31,
1996. Generally,  this requires, at the end of each quarter of the taxable year,
that (a) not more than 25% of each  Series'  total assets be invested in any one
issuer and (b) with respect to 50% of each Series' total assets, no more than 5%
of such  Series'  total  assets  be  invested  in any  one  issuer  except  U.S.
Government securities.

Each Series, as a "diversified" investment company, is prohibited,  with respect
to 75% of the  value of its total  assets,  from  investing  more than 5% of its
total  assets  in  securities  of any one  issuer  other  than  U.S.  Government
securities.  For diversification purposes, the identification of an "issuer" for
the fixed-income  portion of a Series' assets will be determined on the basis of
the source of assets and revenues  committed to meeting  interest and  principal
payments of the securities.  When the assets and revenues of a sovereign state's
political  subdivision are separate from those of the sovereign state government
creating  the  subdivision,  and the  security  is backed only by the assets and
revenues of the subdivision,  then the subdivision  would be considered the sole
issuer.  Similarly,  if a revenue bond is backed only by the assets and revenues
of a nongovernmental user, then such user would be considered the sole issuer.

When-Issued  or  Delayed  Delivery   Securities.   Either  Series  may  purchase
securities on a when-issued basis and, while awaiting delivery and before paying
for them  ("settlement"),  normally may invest in  short-term  securities.  Each
Series does not start earning  interest on these  when-issued  securities  until
settlement  and often  they are sold  prior to  settlement.  During  the  period
between purchase and settlement,  the value of the securities will fluctuate and
assets consisting of cash and/or marketable securities marked to market daily in
an amount  sufficient  to make payment at  settlement  will be segregated at our
custodian in order to pay for the commitment. There is a risk that market yields
available at settlement may be higher than yields obtained on the purchase date,
which could result in depreciation of value.  The other debt securities in which
each Series may invest  include,  but are not limited to,  domestic  and foreign
fixed- and floating-rate notes, bonds, debentures,  convertibles,  certificates,
warrants,  commercial paper and principal and interest pass-through  instruments
issued by governments, authorities, partnerships, corporations, trust companies,
banks and bank holding  companies,  and banker's  acceptances,  certificates  of
deposit, time deposits and deposit notes issued by domestic and foreign banks.
It is currently intended that no more than 5% of each Series' net assets will be
at risk in the use of any one of the policies identified below.

Covered Call Options.  Each Series may write call options on securities it owns,
provided that the securities we hold to cover such options do not represent more
than 5% of a Series' net assets.  A call option on stock gives the  purchaser of
the option,  upon payment of a premium to the writer of the option, the right to
call upon the  writer to deliver a  specified  number of shares of a stock on or
before a fixed date at a predetermined price.

Rights and  Warrants.  Each Series may invest in rights and warrants to purchase
securities  provided  that, at the time of the  acquisition,  its  investment in
warrants,  valued at the  lower of cost or  market,  would not  exceed 5% of the
Series' total assets.  Warrants which are not listed on the New York or American
Stock Exchange or a major foreign  exchange may not exceed 2% of a Series' total
assets.

Repurchase  Agreements.  Each Series may enter into  repurchase  agreements with
respect to a security. A repurchase agreement is a transaction by which a Series
acquires a security and  simultaneously  commits to resell that  security to the
seller (a bank or securities  dealer) at an agreed-upon  price on an agreed-upon
date. Such repurchase agreement must, at all times, be collateralized by cash or
U.S.  Government  securities having a value equal to, or in excess of, the value
of the repurchase agreement.

<PAGE>


Closed-end Investment Companies.  Each Series may invest in shares of closed-end
investment  companies if bought in the primary or secondary market with a fee or
commission no greater than the  customary  broker's  commission.  Shares of such
investment  companies  sometimes  trade at a discount  or premium in relation to
their net asset value and there may be duplication of fees, for example,  to the
extent  that a  Series  and the  closed-end  investment  company  both  charge a
management fee.

Lending of Portfolio Securities.  Each Series may seek to earn income by lending
its  portfolio  securities  if the loan is  collateralized  and its terms are in
accordance with regulatory requirements.

Portfolio  Turnover.  The portfolio turnover rate for the Growth & Income Series
for the fiscal year ended October 31, 1996 was 23.84%.  It is  anticipated  that
the portfolio turnover rate for the International Series will not exceed 100%.
Change of Investment  Objectives  and Policies.  Neither  Series will change its
investment objective without shareholder  approval.  If a Series determines that
its objective can best be achieved by a change in investment policy or strategy,
it may make such change  without  shareholder  approval by  disclosing it in its
prospectus.

5    PURCHASES
ALTERNATIVE SALES ARRANGEMENTS

Classes of Shares.  Each Series  offers  investors  three  different  classes of
shares.  The  different  classes  of shares  represent  investments  in the same
portfolio of securities but are subject to different  expenses and are likely to
have different  share prices.  Investors  should read this section  carefully to
determine which class represents the best investment option for their particular
situation.

Class A Shares.  If you buy Class A shares,  you pay an initial  sales charge on
investments  of less than $1 million (or on investments  for  employer-sponsored
retirement  plans under the Internal  Revenue Code  (hereinafter  referred to as
"Retirement  Plans")  with less than 100  eligible  employees).  If you purchase
Class  A  shares  as  part of an  investment  of at  least  $1  million  (or for
Retirement Plans with at least 100 eligible  employees) in shares of one or more
Lord  Abbett-sponsored  funds, you will not pay an initial sales charge,  but if
you redeem any of those shares within 24 months after the month in which you buy
them, you may pay to the Fund a contingent deferred sales charge ("CDSC") of 1%.
Class A shares are subject to service and  distribution  fees that are currently
estimated  to total  approximately  0.23 of 1% annually  for the Growth & Income
Series and 0.25 of 1% for the International Series of the annual net asset value
of the Class A shares.  The initial  sales charge  rates,  the CDSC and the Rule
12b-1 Plan applicable to the Class A shares are described under "General" below.

Class B Shares.  If you buy Class B shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the sixth  anniversary  of
buying them, you will normally pay a CDSC to Lord Abbett  Distributor llc ("Lord
Abbett  Distributor").  That CDSC varies  depending  on how long you own shares.
Class B shares are subject to service and distribution fees at an annual rate of
1% of the  annual net asset  value of the Class B shares.  The CDSC and the Rule
12b-1 Plan applicable to the Class B shares are described under "General" below.

Class C Shares.  If you buy Class C shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the first  anniversary  of
buying  them,  you will  normally  pay the Fund a CDSC of 1%. Class C shares are
subject to service and  distribution  fees at an annual rate of 1% of the annual
net  asset  value of the  Class C  shares.  The CDSC  and the  Rule  12b-1  Plan
applicable to the C shares are described under "General" below.

Which  Class of Shares  Should You  Choose?  Once you decide that a Series is an
appropriate  investment  for you,  the  decision  as to which class of shares is
better  suited to your needs  depends  on a number of  factors  which you should
discuss with your financial adviser.  Class-specific  expenses and the effect of
the  different  types of sales  charges  on your  investment  will  affect  your
investment  results over time. The most important  factors are how much you plan
to  invest  and how long you plan to hold  your  investment.  If your  goals and
objectives  change over time and you plan to  purchase  additional  shares,  you
should  re-evaluate those factors to see if you should consider another class of
shares.

In the following discussion, to help provide you and your financial adviser with
a framework in which to choose a class,  we have made some  assumptions  using a
hypothetical investment in a Series.

<PAGE>


We used the sales  charge  rates that apply to Class A, Class B and Class C, and
considered  the  effect of the higher  distribution  fees on Class B and Class C
expenses  (which will  affect your  investment  return).  Of course,  the actual
performance  of your  investment  cannot be predicted and will vary,  based on a
Series' actual investment returns, the operating expenses borne by each class of
shares,  and the class of shares you  purchase.  The factors  briefly  discussed
below are not intended to be investment advice,  guidelines or  recommendations,
because each investor's financial  considerations are different.  The discussion
below of the factors to  consider in  purchasing  a  particular  class of shares
assumes that you will purchase only one class of shares and not a combination of
shares of different classes.

How Long Do You Expect to Hold Your  Investment?  While future  financial  needs
cannot be  predicted  with  certainty,  knowing how long you expect to hold your
investment  will assist you in selecting the  appropriate  class of shares.  For
example,  over time, the reduced sales charges available for larger purchases of
Class A shares may offset the effect of paying an initial  sales  charge on your
investment,  compared to the effect over time of higher class-specific  expenses
on Class B or Class C shares for which no initial sales charge is paid.  Because
of the effect of  class-based  expenses,  your choice  should also depend on how
much you plan to invest.

Investing for the Short Term. If you have a short-term  investment horizon (that
is,  you plan to hold your  shares  for not more  than six  years),  you  should
probably  consider  purchasing  Class A or Class C shares  rather  than  Class B
shares.  This is because of the effect of the Class B CDSC if you redeem  before
the sixth  anniversary  of your  purchase,  as well as the effect of the Class B
distribution  fee on the  investment  return for that  class in the short  term.
Class C shares might be the  appropriate  choice  (especially for investments of
less than $100,000), because there is no initial sales charge on Class C shares,
and the CDSC does not apply to amounts you redeem  after  holding them one year.
However,  if you plan to invest more than $100,000 for the short term,  then the
more you invest and the more your investment horizon increases toward six years,
the more  attractive  the Class A share  option may become.  This is because the
annual  distribution  fee on Class C shares  will have a greater  impact on your
account over the longer term than the reduced  front-end sales charge  available
for  larger  purchases  of Class A shares.  For  example,  Class A might be more
appropriate  than Class C for  investments of more than $100,000  expected to be
held for 5 or 6 years (or more).  For investments  over $250,000  expected to be
held 4 to 6 years (or more),  Class A shares may become  more  appropriate  than
Class  C. If you are  investing  $500,000  or  more,  Class  A may  become  more
desirable  as your  investment  horizon  approaches  3 years or  more.  For most
investors  who invest $1 million or more or for  Retirement  Plans with at least
100  eligible  employees,  in  most  cases  Class  A  shares  will  be the  most
advantageous choice, no matter how long you intend to hold your shares. For that
reason, Lord Abbett Distributor normally will not accept purchase orders (i) for
Class B shares of $500,000 or more and for Class C shares of  $1,000,000 or more
from a single investor or (ii) for Class B or C shares for Retirement Plans with
at least 100 eligible employees.

Investing  for the Longer Term.  If you are  investing  for the longer term (for
example,  to provide  for future  college  expenses  for your  child) and do not
expect to need access to your money for seven years or more,  Class B shares may
be an appropriate  investment  option, if you plan to invest less than $100,000.
If you plan to invest more than $100,000 over the long term, Class A shares will
likely be more  advantageous than Class B shares or Class C shares, as discussed
above,  because of the effect of the expected  lower expenses for Class A shares
and the reduced initial sales charges available for larger  investments in Class
A shares under the Fund's Rights of Accumulation.

Of course,  these examples are based on  approximations of the effect of current
sales charges and expenses on a  hypothetical  investment  over time, and should
not be relied on as rigid guidelines.

Are There  Differences  in Account  Features  That Matter to You?  Some  account
features  are  available  in whole or in part to  Class A,  Class B and  Class C
shareholders.  Other features (such as Systematic Withdrawal Plans) might not be
advisable in non-Retirement  Plan accounts for Class B shareholders  (because of
the effect of the CDSC on the entire  amount of a  withdrawal  if it exceeds 12%
annually) and in any account for Class C  shareholders  during the first year of
share  ownership  (due  to the  CDSC  on  withdrawals  during  that  year).  See
"Systematic  Withdrawal Plan" under "Shareholder  Services" for more information
about the 12% annual  waiver of the CDSC.  You should  carefully  review how you
plan to use your  investment  account before  deciding which class of shares you
buy. For example, the dividends payable to Class B and Class C shareholders will
be reduced by the expenses  borne solely by each of these  classes,  such as the
higher  distribution  fee to which  Class B and Class C shares are  subject,  as
described below.

How Does It Affect Payments to My Broker?  A salesperson,  such as a broker,  or
any other person who is entitled to receive compensation for selling Fund shares
may  receive  different  compensation  for  selling  one class than for  selling
another class. As discussed in more detail below, such compensation is primarily
paid at the time of sale in the case of  Class A and B shares  and is paid  over
time, so long as shares remain outstanding, in the case of Class C shares. It is
important that investors understand that the primary purpose of the CDSC for the
Class B shares  and the  distribution  fee for Class B and Class C shares is the
same as the purpose of the front-end sales charge on sales of Class A shares: to
compensate  brokers and other persons selling such shares. The CDSC, if payable,
supplements  the Class B  distribution  fee and reduces the Class C distribution
fee expenses for each Series and Class C shareholders.

GENERAL
How  Much  Must You  Invest?  You may buy our  shares  through  any  independent
securities  dealer having a sales  agreement with Lord Abbett  Distributor,  our
exclusive selling agent. Place your order with your investment dealer or send it
to Lord Abbett Securities Trust (P.O. Box 419100,  Kansas City, Missouri 64141).
The  minimum  initial   investment  for  each  Series  is  $1,000,   except  for
Invest-A-Matic  and  Div-Move  ($250  initial and $50  subsequent  minimum)  and
Individual Retirement Accounts ($250 minimum).  For Retirement Plans there is no
minimum initial investment required. See "Shareholder Services." For information
regarding  the proper form of a purchase or redemption  order,  call the Fund at
800-821-5129.  This offering may be suspended, changed or withdrawn. Lord Abbett
Distributor  reserves the right to reject any order.  The net asset value of our
shares is  calculated  every  business day as of the close of the New York Stock
Exchange  ("NYSE") by dividing  net assets by the number of shares  outstanding.
Securities  are  valued at their  market  value as more fully  described  in the
Statement of Additional Information.

Buying Shares Through Your Dealer.  Orders for shares received by the Fund prior
to the  close of the  NYSE,  or  received  by  dealers  prior to such  close and
received by Lord Abbett Distributor prior to the close of its business day, will
be confirmed at the  applicable  public  offering  price  effective at such NYSE
close.  Orders  received by dealers  after the NYSE closes and  received by Lord
Abbett  Distributor  in proper form prior to the close of its next  business day
are executed at the applicable  public  offering price effective as of the close
of the NYSE on that next business day. The dealer is responsible  for the timely
transmission  of orders to Lord Abbett  Distributor.  A business day is a day on
which the NYSE is open for trading.  Lord Abbett  Distributor may, for specified
periods,  allow  dealers  to retain  the full  sales  charge for sales of shares
during such periods,  or pay an additional  concession to a dealer who, during a
specified  period,  sells a minimum dollar amount of our shares and/or shares of
other  Lord   Abbett-sponsored   funds.  In  some  instances,   such  additional
concessions will be offered only to certain dealers expected to sell significant
amounts of shares.  Lord Abbett  Distributor  may, from time to time,  implement
promotions  under which Lord Abbett  Distributor  will pay a fee to dealers with
respect  to  certain  purchases  not  involving  imposition  of a sales  charge.
Additional payments may be paid from Lord Abbett Distributor's own resources and
will be made in the  form of cash  or,  if  permitted,  non-cash  payments.  The
non-cash  payments will include business seminars at resorts or other locations,
including  meals and  entertainment,  or the  receipt of  merchandise.  The cash
payments will include  payment of various  business  expenses of the dealer.  In
selecting dealers to execute portfolio transactions for the Fund's portfolio, if
two or more dealers are considered  capable of obtaining best execution,  we may
prefer  the  dealer  who has  sold  our  shares  and/or  shares  of  other  Lord
Abbett-sponsored funds.

Buying  Class A  Shares.  The  offering  price of Class A shares is based on the
per-share  net asset value next  computed  after your order is  accepted  plus a
sales charge as follows.

Class A Share Volume  Discounts.  This section describes several ways to qualify
for a lower  sales  charge  when  purchasing  Class A shares if you inform  Lord
Abbett  Distributor  or the Fund that you are  eligible at the time of purchase.
(1) Any purchaser (as described below) may aggregate a Class A share purchase in
the Fund with any share  purchases of any other  eligible Lord  Abbett-sponsored
fund, together with the current value at maximum offering price of any shares in
the Fund and in any eligible Lord Abbett-sponsored  funds held by the purchaser.
(Holdings  in the  following  funds are not  eligible  for the  above  rights of
accumulation:  Lord  Abbett  Equity  Fund  ("LAEF"),  Lord  Abbett  Series  Fund
("LASF"),  any series of Lord  Abbett  Research  Fund not offered to the general
public  ("LARF") and Lord Abbett U.S.  Government  Securities  Money Market Fund
("GSMMF"),  except for  holdings in GSMMF which are  attributable  to any shares
exchanged  from  a Lord  Abbett-sponsored  fund.)  (2) A  purchaser  may  sign a
non-binding  13-month  statement of  intention to invest  $50,000 or more in any
shares  of the  Fund or in any of the  above  eligible  funds.  If the  intended
purchases  are  completed  during the period,  the total amount of your intended
purchases  of any shares will  determine  the reduced  sales charge rate for the
Class A shares purchased during the period. If not completed, each Class A share
purchase  will be at the sales  charge for the  aggregate  of the  actual  share
purchases. Shares issued upon reinvestment of dividends or distributions are not
included in the statement of  intention.  The term  "purchaser"  includes (i) an
individual,  (ii) an individual and his or her spouse and children under the age
of 21 and (iii) a trustee  or other  fiduciary  purchasing  shares  for a single
trust estate or single fiduciary account  (including a pension,  profit-sharing,
or other  employee  benefit  trust  qualified  under Section 401 of the Internal
Revenue  Code -- more  than one  qualified  employee  benefit  trust of a single
employer,  including its consolidated  subsidiaries,  may be considered a single
trust, as may qualified plans of multiple employers  registered in the name of a
single bank  trustee as one  account),  although  more than one  beneficiary  is
involved.

Class A Share Net Asset Value Purchases.  Our Class A shares may be purchased at
net asset value by our  directors,  employees of Lord  Abbett,  employees of our
shareholder  servicing  agent and  employees of any  securities  dealer having a
sales  agreement with Lord Abbett  Distributor who consents to such purchases or
by the trustee or custodian under any pension or profit-sharing  plan or Payroll
Deduction IRA  established for the benefit of such persons or for the benefit of
any national  securities trade  organization to which Lord Abbett or Lord Abbett
Distributor  belongs or any company with an  account(s) in excess of $10 million
managed by Lord Abbett on a private-advisory-account basis. For purposes of this
paragraph,  the  terms  "directors"  and  "employees"  include a  director's  or
employee's  spouse  (including  the surviving  spouse of a deceased  director or
employee).  The terms  "directors"  and  "employees of Lord Abbett" also include
other family  members and retired  directors and  employees.  Our Class A shares
also may be  purchased  at net asset  value (a) at $1 million or more,  (b) with
dividends  and  distributions  on Class A shares of other Lord  Abbett-sponsored
funds,  except for dividends and distributions on shares of LARF, LAEF and LASF,
(c) under the loan feature of the Lord  Abbett-sponsored  prototype  403(b) plan
for  Class A  share  purchases  representing  the  repayment  of  principal  and
interest,  (d) by certain authorized  brokers,  dealers,  registered  investment
advisers or other financial institutions who have entered into an agreement with
Lord Abbett  Distributor in accordance with certain  standards  approved by Lord
Abbett Distributor,  providing specifically for the use of our Class A shares in
particular  investment  products  made  available  for a fee to  clients of such
brokers,   dealers,   registered   investment   advisers  and  other   financial
institutions ("mutual fund wrap fee programs"),  (e) by employees,  partners and
owners of  unaffiliated  consultants  and advisers to Lord  Abbett,  Lord Abbett
Distributor or Lord Abbett-sponsored  funds who consent to such purchase if such
persons provide services to Lord Abbett,  Lord Abbett  Distributor or such funds
on a continuing basis and are familiar with such fund and (f) through Retirement
Plans with at least 100 eligible employees.

Class A Rule 12b-1 Plan. The Fund has adopted a Class A share Rule 12b-1 Plan on
behalf of each Series (the "A Plans,"  each, an "A Plan") which  authorizes  the
payment of fees to authorized  institutions  (except as to certain  accounts for
which tracking data is not available) in order to provide additional  incentives
for them (a) to provide continuing  information and investment services to their
Class A shareholder accounts and otherwise to encourage those accounts to remain
invested in the Series and (b) to sell Class A shares of the Series.  Under each
A Plan, in order to save on the expense of shareholders' meetings and to provide
flexibility  to the Board of  Trustees,  the Board,  including a majority of the
outside directors who are not "interested  persons" of each Series as defined in
the Act, is  authorized  to approve  annual fee payments  from a Series' Class A
assets  of up to 0.50 of 1% of the  average  net of such  assets  consisting  of
distribution  and service fees, each at a maximum annual rate not exceeding 0.25
of 1% (the "Fee Ceiling").

Under the A Plans, the Board has approved  payments by the Series to Lord Abbett
Distributor  which uses or passes on to  authorized  institutions  (1) an annual
service fee (payable  quarterly) of .25% of the average daily net asset value of
the  Class A shares  serviced  by  authorized  institutions  and (2) a  one-time
distribution fee of up to 1% (reduced according to the following schedule: 1% of
the first $5 million,  .55% of the next $5 million, .50% of the next $40 million
and .25% over $50  million),  payable  at the time of sale on all Class A shares
sold during any  12-month  period  starting  from the day of the first net asset
value sale (i) at the $1 million  level by  authorized  institutions,  including
sales qualifying at such level under the rights of accumulation and statement of
intention privileges or (ii) through Retirement Plans with at least 100 eligible
employees. In addition, the Board has approved for those authorized institutions
which qualify,  a  supplemental  annual  distribution  fee equal to 0.10% of the
average  daily net  asset  value of the Class A shares  serviced  by  authorized
institutions which have a satisfactory  program for the promotion of such shares
comprising a  significant  percentage  of the Class A assets,  with a lower than
average  redemption rate.  Institutions and persons  permitted by law to receive
such fees are "authorized institutions."

Under the A Plans, Lord Abbett Distributor is permitted to use payments received
to provide continuing  services to Class A shareholder  accounts not serviced by
authorized  institutions and, with Board approval, to finance any activity which
is primarily intended to result in the sale of Class A shares. Any such payments
are subject to the Fee Ceiling.  Any  payments  under the Plans not used by Lord
Abbett  Distributor  in this  manner are passed on to  authorized  institutions.
Holders of Class A shares on which the 1% sales  distribution  fee has been paid
may be  required  to pay to the Series on behalf of its Class A shares a CDSC of
1% of the original  cost or the then net asset value,  whichever is less, of all
Class A shares so purchased which are redeemed out of the Lord  Abbett-sponsored
family of funds on or before the end of the twenty-fourth  month after the month
in  which  the  purchase  occurred.  (Exceptions  are made  for  redemptions  by
Retirement  Plans  due to any  benefit  payment  such  as plan  loans,  hardship
withdrawals,  death,  retirement or separation from service with respect to plan
participants  or the  distribution of any excess  contributions.  If the Class A
shares have been  exchanged  into  another  Lord  Abbett-sponsored  fund and are
thereafter  redeemed out of the Lord Abbett family of funds on or before the end
of such twenty-fourth  month, the charge will be collected for the Series' Class
A shares by the other fund. The Series will collect such a charge for other Lord
Abbett-sponsored funds in a similar situation.

Buying  Class B Shares.  Class B shares  are sold at net  asset  value per share
without an initial  sales  charge.  However,  if Class B shares are redeemed for
cash before the sixth anniversary of their purchase, a CDSC may be deducted from
the redemption proceeds. That sales charge will not apply to shares purchased by
the reinvestment of dividends or capital gains distributions. The charge will be
assessed  on the  lesser  of the net  asset  value of the  shares at the time of
redemption  or the  original  purchase  price.  The Class B CDSC is paid to Lord
Abbett Distributor to compensate it for its services rendered in connection with
the distribution of Class B shares, including the payment and financing of sales
commissions. See "Class B Rule 12b-1 Plan" below.

To determine  whether the CDSC applies to a redemption,  the Fund redeems shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends and
capital  gains  distributions,  (2) shares held until the sixth  anniversary  of
their  purchase  or later,  and (3)  shares  held the  longest  before the sixth
anniversary of their purchase.


<PAGE>


The amount of the CDSC will depend on the number of years since you invested and
the dollar amount being redeemed, according to the following schedule.

In the table,  an  "anniversary"  is the 365th day subsequent to a purchase or a
prior  anniversary.  All  purchases  are  considered  to have  been  made on the
business  day the  purchase was made.  See "Buying  Shares  Through Your Dealer"
above.
If  Class  B  shares  are  exchanged   into  the  same  class  of  another  Lord
Abbett-sponsored  fund and the new shares  are  subsequently  redeemed  for cash
before the sixth anniversary of the original purchase,  the CDSC will be payable
on the new shares on the basis of the time elapsed  from the original  purchase.
The Series will collect such a charge for other Lord Abbett-sponsored funds in a
similar situation.

Waiver of Class B Sales Charges.  The Class B CDSC will not be applied to shares
purchased in certain types of transactions  nor will it apply to shares redeemed
in certain circumstances as described below.
The Class B CDSC will be waived for redemptions of shares (i) in connection with
the  Systematic  Withdrawal  Plan and  Div-Move  services,  as described in more
detail under  "Shareholder  Services" below; (ii) by Retirement Plans due to any
benefit payment such as plan loans, hardship withdrawals,  death,  retirement or
separation from service with respect to plan participants or the distribution of
any excess contributions, (iii) in connection with mandatory distributions under
403(b) plans and individual  retirement accounts and (iv) in connection with the
death of an individual shareholder (a natural person).

Class B Rule 12b-1 Plan. The Fund has adopted a Class B share Rule 12b-1 Plan on
behalf of each  Series (the "B Plans,"  each a "B Plan")  under which the Series
periodically  pays (except as to certain accounts for which tracking data is not
available)  Lord Abbett  Distributor  (i) an annual service fee of 0.25 of 1% of
the  average  daily  net asset  value of the  Class B shares  and (ii) an annual
distribution fee of 0.75 of 1% of the average daily net asset value of the Class
B shares that are  outstanding  for less than 8 years.  Lord Abbett  Distributor
uses  the  service  fee to  compensate  authorized  institutions  for  providing
personal  services for  accounts  that hold Class B shares.  Those  services are
primarily similar to those provided under the A Plan, described above.
Lord Abbett  Distributor  pays an up-front  payment to  authorized  institutions
totaling 4%, consisting of 0.25% for service and 3.75% for a sales commission as
described below.
Lord Abbett Distributor pays the 0.25% service fee to authorized institutions in
advance for the first year after Class B shares have been sold by the authorized
institutions.  After  the  shares  have  been  held  for  a  year,  Lord  Abbett
Distributor pays the service fee on a quarterly basis.  Lord Abbett  Distributor
is entitled to retain such service fee payable  under the B Plan with respect to
accounts  for which there is no  authorized  institution  of record or for which
such authorized  institution  did not qualify.  Although not obligated to do so,
Lord Abbett  Distributor may waive receipt from the Series or part or all of the
service fee payments.

The  0.75%  annual  distribution  fee is  paid  to Lord  Abbett  Distributor  to
compensate it for its services  rendered in connection with the  distribution of
Class B shares,  including  the  payment  and  financing  of sales  commissions.
Although Class B shares are sold without a front-end  sales charge,  Lord Abbett
Distributor pays authorized institutions responsible for sales of Class B shares
a sales  commission of 3.75% of the purchase price.  This payment is made at the
time of sale from Lord Abbett Distributor's own resources.  Lord Abbett has made
arrangements to finance these commission  payments,  which arrangements  include
non-recourse  assignments by Lord Abbett  Distributor to the financing  party of
such distribution and CDSC payments which are made to Lord Abbett Distributor by
shareholders who redeem their Class B shares within six years of their purchase.
The  distribution  fee and CDSC payments  described above allow investors to buy
Class B shares  without a front-end  sales  charge  while  allowing  Lord Abbett
Distributor to compensate authorized  institutions that sell Class B shares. The
CDSC is intended to supplement Lord Abbett  Distributor's  reimbursement for the
commission  payments it has made with  respect to Class B shares and its related
distribution  and financing  costs. The distribution fee payments are at a fixed
rate and the CDSC payments are of a nature that,  during any year, both forms of
payment may not be  sufficient  to  reimburse  Lord Abbett  Distributor  for its
actual  expenses.  The Series is not liable for any  expenses  incurred  by Lord
Abbett Distributor in excess of (i) the amount of such distribution fee payments
to be received by Lord Abbett  Distributor  and (ii)  unreimbursed  distribution
expenses of Lord Abbett  Distributor  incurred in a prior plan year,  subject to
the right of the Board of Trustees or shareholders to terminate the B Plan. Over
the long term, the expenses incurred by Lord Abbett Distributor are likely to be
greater than such distribution fee and CDSC payments. Nevertheless, there exists
a possibility that for a short-term period Lord Abbett  Distributor may not have
sufficient expenses to warrant reimbursement by receipt of such distribution fee
payments. Although Lord Abbett Distributor undertakes not to make a profit under
the B Plan,  the B Plan is considered a  compensation  plan (i.e.,  distribution
fees are paid regardless of expenses incurred) in order to avoid the possibility
of Lord Abbett  Distributor not being able to receive  distribution fees because
of a temporary timing difference  between its incurring  expenses and receipt of
such distribution fees.


<PAGE>


Automatic  Conversion  of Class B  Shares.  On the  eighth  anniversary  of your
purchase of Class B shares,  those shares will automatically  convert to Class A
shares.  This  conversion  relieves  Class B  shareholders  of the higher annual
distribution  fee that  applies  to Class B shares  under the Class B Rule 12b-1
Plan.  The  conversion  is based on the  relative  net  asset  values of the two
classes,  and no sales  charge or other  charge is imposed.  When Class B shares
convert,  any other Class B shares that were  acquired  by the  reinvestment  of
dividends  and  distributions  will also convert to Class A shares on a pro rata
basis.  The conversion  feature is subject to the continued  availability  of an
opinion of counsel or of a tax ruling  described in "Purchases,  Redemptions and
Shareholder Services" in the Statement of Additional Information.

Buying  Class C Shares.  Class C shares  are sold at net  asset  value per share
without an initial  sales  charge.  However,  if Class C shares are redeemed for
cash  before  the  first  anniversary  of their  purchase,  a CDSC of 1% will be
deducted from the redemption proceeds.  That reimbursement charge will not apply
to  shares   purchased  by  the  reinvestment  of  dividends  or  capital  gains
distributions.  The charge will be assessed on the lesser of the net asset value
of the shares at the time of  redemption  or the original  purchase  price.  The
Class C CDSC is paid to the Series to reimburse it, in whole or in part, for the
service and distribution fee payments made by the Series at the time such shares
were sold, as described below.

To determine whether the CDSC applies to a redemption, the Series redeems shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends and
capital gains distributions, (2) shares held for one year or more and (3) shares
held the longest  before the first  anniversary  of their  purchase.  If Class C
shares are exchanged into the same class of another Lord  Abbett-sponsored  fund
and  subsequently  redeemed  before  the  first  anniversary  of their  original
purchase,  the  charge  will be  collected  by the  other  fund on behalf of the
Series'  Class C shares.  The Series will  collect  such a charge for other Lord
Abbett-sponsored funds in a similar situation.

Class C Rule 12b-1 Plan. The Fund has adopted a Class C share Rule 12b-1 Plan on
behalf of each Series (the "C Plans", each a "C Plan") under which (except as to
certain  accounts  for which  tracking  data is not  available)  the Series pays
authorized  institutions through Lord Abbett Distributor (1) a service fee and a
distribution  fee, at the time  shares are sold,  not to exceed 0.25 and 0.75 of
1%,  respectively,  of the  net  asset  value  of  such  shares  and (2) at each
quarter-end after the first anniversary of the sale of shares, fees for services
and   distribution  at  annual  rates  not  to  exceed  0.25  and  0.75  of  1%,
respectively,  of the average annual net asset value of such shares  outstanding
(payments with respect to shares not  outstanding  during the full quarter to be
prorated). These service and distribution fees are for purposes similar to those
mentioned  above with respect to the A Plan.  Sales in clause (1) exclude shares
issued for  reinvested  dividends and  distributions  and shares  outstanding in
clause (2) include  shares issued for  reinvested  dividends  and  distributions
after the first anniversary of their issuance.

6    SHAREHOLDER SERVICES

We offer the following shareholder services:
Telephone  Exchange  Privilege:  Shares of any class may be exchanged  without a
service   charge:   (a)  for  shares  of  the  same  class  of  any  other  Lord
Abbett-sponsored  fund  except  for (i)  LAEF,  LASF and  LARF and (ii)  certain
tax-free,  single-state series where the exchanging shareholder is a resident of
a state in which such  series is not  offered for sale and (b) for shares of any
authorized  institution's  affiliated  money market fund  satisfying Lord Abbett
Distributor  as  to  certain  omnibus  account  and  other  criteria  (together,
"Eligible Funds").

You or your representative  with proper  identification can instruct the Fund to
exchange  uncertificated  shares  of a class  (held by the  transfer  agent)  by
telephone.  Shareholders  have this privilege  unless they refuse it in writing.
The Fund will not be liable for following instructions communicated by telephone
that it reasonably believes to be genuine and will employ reasonable  procedures
to confirm that instructions  received are genuine,  including requesting proper
identification  and  recording  all telephone  exchanges.  Instructions  must be
received  by the Fund in Kansas  City  (800-821-5129)  prior to the close of the
NYSE to  obtain  each  fund's  net  asset  value  per  class  share on that day.
Expedited  exchanges  by  telephone  may be  difficult  to implement in times of
drastic economic or market change.  The exchange privilege should not be used to
take advantage of short-term  swings in the market.  The Fund reserves the right
to  terminate  or limit the  privilege  of any  shareholder  who makes  frequent
exchanges.  The Fund can revoke the privilege for all shareholders upon 60 days'
prior written  notice.  A prospectus  for the other Lord  Abbett-sponsored  fund
selected by you should be obtained and read before an exchange.  Exercise of the
Exchange  Privilege  will be treated as a sale for federal  income tax  purposes
and, depending on the circumstances, a capital gain or loss may be recognized.

Systematic Withdrawal Plan ("SWP"):  Except for Retirement Plans for which there
is no such minimum,  if the maximum offering price value of your  uncertificated
shares is at least $10,000, you may have periodic cash withdrawals automatically
paid to you in either fixed or variable amounts. With respect to Class B shares,
the CDSC will be waived on  redemptions of up to 12% per year of the current net
asset  value of your  account at the time your SWP is  established.  For Class B
shares (over 12% per year) and C shares,  redemption  proceeds due to a SWP will
be derived from the following  sources in the order listed:  (1) shares acquired
by reinvestment of dividends and capital gains, (2) shares held for six years or
more  (Class B) or one year or more  (Class C); and (3) shares  held the longest
before the sixth  anniversary  of their  purchase  (Class B) or before the first
anniversary of their purchase (Class C). For Class B share  redemptions over 12%
per year,  the CDSC  will  apply to the  entire  redemption.  Therefore,  please
contact  the Fund  for  assistance  in  minimizing  the CDSC in this  situation.
Shareholders  should be careful in establishing a SWP,  especially to the extent
that such a withdrawal  exceeds the annual  total  return for a class,  in which
case, the shareholder's  original  principal will be invaded and, over time, may
be depleted.

Div-Move:  You can  invest  the  dividends  paid on your  account  ($50  minimum
investment) into an existing account within the same class in any Eligible Fund.
The  account  must be either  your  account,  a joint  account  for you and your
spouse,  a single account for your spouse or a custodial  account for your minor
child under the age of 21.  Such  dividends  will not be subject to a CDSC.  You
should read the prospectus of the other fund before investing.

Invest-A-Matic:   You  can  make  fixed,   periodic   investments  ($50  minimum
investment) into the Series and/or any Eligible Fund by means of automatic money
transfers from your bank checking account. You should read the prospectus of the
other fund before investing.

Retirement  Plans:  Lord Abbett makes  available the  retirement  plan forms and
custodial  agreements for IRAs (Individual  Retirement Accounts including Simple
IRAs, Simplified Employee Pensions), 403(b) plans and pension and profit-sharing
plans, including 401(k) plans.

Householding:  A single copy of an annual or semi-annual  report will be sent to
an address to which more than one  registered  shareholder  of the Fund with the
same last name has indicated mail is to be delivered,  unless additional reports
are specifically requested in writing or by telephone.

All correspondence  should be directed to Lord Abbett Securities Trust (P.O. Box
419100, Kansas City, Missouri 64141; 800-821-5129).

7    OUR MANAGEMENT
Our business is managed by our officers on a day-to-day  basis under the overall
direction  of our  Board of  Trustees  with the  advice  of Lord  Abbett  ("Fund
Management").  We  employ  Lord  Abbett  as  investment  manager  pursuant  to a
Management  Agreement.  Lord Abbett has been an  investment  manager for over 67
years and  currently  manages  approximately  $22  billion in a family of mutual
funds and other advisory accounts.  Under the Management Agreement,  Lord Abbett
provides  us  with  investment  management  services  and  personnel,  pays  the
remuneration  of our officers and of our Trustees  affiliated  with Lord Abbett,
provides us with office  space and pays for ordinary  and  necessary  office and
clerical expenses relating to research,  statistical work and supervision of our
portfolios and certain other costs.  Lord Abbett  provides  similar  services to
twelve other Lord  Abbett-sponsored  funds having various investment  objectives
and also advises other investment clients. Lord Abbett Partner Robert G. Morris,
serves as Executive Vice President and portfolio manager for the Growth & Income
Series.  Mr.  Morris has been with Lord  Abbett for over five years and has over
twenty-five  years  of  investment  experience.  Christopher  Taylor  serves  as
portfolio  manager of the  International  Series.  Mr. Taylor is Deputy Managing
Director of Fuji Investment  Management Co. (Europe),  Ltd. (the "Sub-Adviser").
He has been with the Sub-Adviser and its predecessor since 1987 and has 15 years
of investment experience.

Lord Abbett has entered into an agreement with the Sub-Adviser,  under which the
Sub-Adviser  provides Lord Abbett with advice with respect to the  International
Series' assets. The Sub-Adviser is controlled by Fuji Investment  Management Co.
(Tokyo).  Fuji Bank Limited of Tokyo,  Japan ("Fuji Bank")  directly owns 40% of
the outstanding voting stock of the Sub-Adviser.  Fuji Investment Management Co.
(Tokyo)  is an  affiliate  of Fuji Bank.  Lord  Abbett  indirectly  owns a minor
percentage of such outstanding voting stock. As of June 1, 1997, the Sub-Adviser
manages approximately $577 million,  which is invested globally. The Sub-Adviser
furnishes  Lord  Abbett  with  advice and  recommendations  with  respect to the
International   Series'  assets,   including  advice  about  the  allocation  of
investments  among  foreign  securities  markets  and  foreign  equity  and debt
securities  markets  and  foreign  equity and debt  securities  and,  subject to
consultation with Lord Abbett, advice as to cash holdings and what securities in
the portfolio  should be purchased,  held or disposed of. The  Sub-Adviser  also
gives advice with respect to foreign currency  matters.  Although,  under normal
circumstances,  the International Series will be invested at least 80% in equity
securities  of  non-U.S.  issuers,  subject  to the  direction  of the  Board of
Trustees,  Lord Abbett, in consultation with the Sub-Adviser,  will determine at
least quarterly,  and more frequently as Lord Abbett determines,  the percentage
of assets of the  International  Series  that  shall be  allocated  (the  "Asset
Allocation")  for  investment  in the  United  States  and in  foreign  markets,
respectively.  Under the  Management  Agreement,  we are  obligated  to pay Lord
Abbett a monthly  fee at the  annual  rate of 0.75 of 1% for each  Series.  With
respect  to  the  International  Series,  Lord  Abbett,  when  not  waiving  its
management  fee,  is  obligated  to pay the  Sub-Adviser  a monthly fee equal to
one-half of Lord  Abbett's fee as described  above.  Regardless  of such waiver,
Lord Abbett is free to pay the Sub-Adviser. For the year ended October 31, 1996,
Lord  Abbett  had waived  $242,341  in  management  fees for the Growth & Income
Series.  For the same  period,  the Class C share ratio of  expenses,  including
management fees, to average net assets was 1.55%. For the same period,  had Lord
Abbett not waived its management fee and assumed certain  expenses,  the Class C
share  expense  ratio would have been 2.01%.  As of July 12,  1996,  Lord Abbett
discontinued its waiver of the Growth & Income Series' management fee.

We will not hold annual  meetings  and expect to hold  meetings of  shareholders
only when necessary under applicable law or the terms of the Fund's  Declaration
of Trust. Under the Declaration of Trust, a shareholders'  meeting may be called
at the request of the holders of one-quarter of the outstanding  shares entitled
to vote. See the Statement of Additional Information for more details. The Fund.
The Fund was organized as a Delaware  business  trust on February 26, 1993.  Its
Class  A,  B and  C  shares  have  equal  rights  as to  voting,  dividends  and
distributions  except for  differences  resulting  from  certain  class-specific
expenses.

8    DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES

Dividends from net investment  income are paid to  shareholders  of the Growth &
Income  Series  quarterly  and  International   Series  annually.   Supplemental
dividends may be paid by each Series in December or January.  Dividends from net
investment income may be taken in cash or reinvested in additional shares at net
asset value without a sales charge. If you elect a cash payment (i) a check will
be mailed to you as soon as possible after the monthly reinvestment date or (ii)
if you arrange for direct  deposit,  your payment will be wired directly to your
bank account within one day after the date on which the dividend is paid.

A  long-term  capital  gains  distribution  is made by a Series  when it has net
profits during the year from sales of securities which it has held more than one
year.  If a Series  realizes net  short-term  capital  gains,  they also will be
distributed.  It is  anticipated  that  capital  gains  will be  distributed  in
December or January.  You may take them in cash or additional  shares  without a
sales charge. Dividends declared in October, November or December of any year to
shareholders  of record as of a date in such a month will be treated for federal
income tax purposes as having been received by shareholders in that year if they
are paid  before  February 1 of the  following  year.  Shareholders  must report
dividends  and capital  gains  distributions  as taxable  income.  Distributions
derived from net  long-term  capital  gains which are  designated by a Series as
"capital  gains  distributions"  will be taxable to  shareholders  as  long-term
capital  gains,  whether  received in cash or shares,  regardless  of how long a
taxpayer has held the shares. Under current law, net long-term capital gains are
taxed at the rates applicable to ordinary  income,  except that the maximum rate
for long-term  capital gains for individuals is 28%.  Recently,  legislation has
been proposed that would have the effect of reducing the federal income tax rate
on capital gains.

Each Series may be subject to foreign  withholding  taxes which would reduce the
yield on their  investments.  Tax treaties  between  certain  countries  and the
United  States  may  reduce  or  eliminate  such  taxes.  See the  Statement  of
Additional Information for additional details.
Shareholders may be subject to a $50 penalty under the Internal Revenue Code and
we may be required to withhold and remit to the U.S. Treasury a portion (31%) of
any redemption or repurchase  proceeds  (including the value of shares exchanged
into  another  Lord  Abbett-sponsored  fund)  and of  any  taxable  dividend  or
distribution on any account where the payee failed to provide a correct taxpayer
identification number or to make certain required certifications.

We will  inform  shareholders  of the federal  tax status of each  dividend  and
distribution  after the end of each calendar year.  Shareholders  should consult
their tax advisers  concerning  applicable  state and local taxes as well as the
tax  consequences  of gains or losses  from the  redemption  or  exchange of our
shares.

9    REDEMPTIONS
To obtain the proceeds of an  expedited  redemption  of $50,000 or less,  you or
your representative with proper  identification can telephone the Fund. The Fund
will not be liable for following instructions  communicated by telephone that it
reasonably  believes  to be genuine  and will employ  reasonable  procedures  to
confirm that  instructions  received are genuine,  including  requesting  proper
identification,  recording  all telephone  redemptions  and mailing the proceeds
only  to  the  named  shareholder  at  the  address  appearing  on  the  account
registration.

If you do not qualify for the  procedure  above,  send your  written  redemption
request to Lord Abbett Securities Trust (P.O. Box 419100,  Kansas City, Missouri
64141) with  signature(s) and any legal capacity of the signer(s)  guaranteed by
an eligible guarantor  accompanied by any certificates for shares to be redeemed
and other  required  documentation.  Payment will be made within three  business
days.  The Fund may suspend  the right to redeem  shares for not more than three
days (or longer under unusual circumstances as permitted by Federal law). If you
have  purchased  Series'  shares by check and  subsequently  submit a redemption
request, redemption proceeds will be paid upon clearance of your purchase check,
which may take up to 15 days.  To avoid delays you may arrange for the bank upon
which a check was drawn to communicate to the Fund that the check has cleared.

Shares  also  may be  redeemed  by the  Fund at net  asset  value  through  your
securities dealer who, as an unaffiliated  dealer, may charge you a fee. If your
dealer receives your order prior to the close of the NYSE and communicates it to
Lord Abbett, as our agent, prior to the close of Lord Abbett's business day, you
will receive the net asset value of the shares being redeemed as of the close of
the NYSE on that day. If the dealer does not  communicate  such an order to Lord
Abbett until the next  business  day, you will receive the net asset value as of
the close of the NYSE on that next business day.  Shareholders who have redeemed
their shares have a one-time  right to reinvest,  in another  account having the
identical  class  and  registration,  in any of the  Eligible  Funds at the then
applicable net asset value without the payment of a front-end sales charge. Such
reinvestment  must be made within 60 days of the redemption and is limited to no
more than the amount of the redemption proceeds.

Under certain  circumstances  and subject to prior written notice,  our Board of
Trustees may  authorize  redemption of all of the shares in any account in which
there are fewer than 50 shares.
Tax-qualified   Plans:  For  redemptions  of  $50,000  or  less,  follow  normal
redemption  procedures.  Redemptions  over  $50,000  must be in writing from the
employer,  broker or plan  administrator  stating the reason for the redemption.
The  reason  for the  redemption  must be  received  by the Fund  prior  to,  or
concurrent with, the redemption request.

10   PERFORMANCE

Lord Abbett  Securities  Trust - Growth & Income  Series  closed  fiscal 1996 on
October 31 with  assets of  $113,961,747.  During the year,  the Growth & Income
Series and the financial markets in general  performed well.  Following are some
of the factors that were relevant to the Series' performance over the past year,
including  market  conditions  and investment  strategies  pursued by the Fund's
management.

Over the past year,  the stock market  remained  near all- time highs  against a
background of modest economic growth, low inflation and a volatile interest-rate
environment.   We  mainly  identified  investment  opportunities  based  on  the
characteristics of individual  securities,  as few areas (sectors) of the market
represented  extraordinary  value. One exception was the financial sector, where
we were heavily weighted. These holdings performed strongly and helped to offset
disappointments from our technology holdings.

Yield and Total  Return.  Yield and total return data may, from time to time, be
included in  advertisements  about each Series.  Each class of shares calculates
its "yield" by dividing the annualized  net  investment  income per share on the
portfolio  during a 30-day period by the maximum  offering price on the last day
of the  period.  The yield of each class will  differ  because of the  different
expenses  (including actual 12b-1 fees) of each class of shares.  The yield data
represents  a  hypothetical  investment  return on the  portfolio,  and does not
measure an investment  return based on dividends  actually paid to shareholders.
To show  that  return,  a  dividend  distribution  rate may be  calculated.  The
dividend  distribution  rate is  calculated by dividing the dividends of a class
derived  from  net  investment  income  during a stated  period  by the  maximum
offering price on the last day of the period.  Yields and dividend  distribution
rates for Class A shares  reflect the  deduction  of the maximum  initial  sales
charge,  but may also be shown  based on a Series'  net asset  value per  share.
Yields for Class C shares do not reflect the deduction of the CDSC.

"Total return" for the one-, five- and ten-year  periods  represents the average
annual  compounded  rate of return on an  investment of $1,000 in each Series at
the  maximum  public  offering  price.  When total  return is quoted for Class A
shares, it includes the payment of the maximum initial sales charge.  When total
return is shown for Class C shares,  it  reflects  the effect of the  applicable
CDSC.  Total  return  also  may be  presented  for  other  periods  or  based on
investments at reduced sales charge levels or net asset value.  Any quotation of
total return not  reflecting  the maximum  sales charge  (front-end,  level,  or
back-end)  would be reduced if such sales charge were used.  Quotations of yield
or total return for any period when an expense  limitation  is in effect will be
greater than if the limitation had not been in effect. See "Past Performance" in
the Statement of Additional Information for a more detailed description.

See "Performance" in the Statement of Additional Information for a more detailed
discussion concerning the computation of each Series' total return and yield.

LORD ABBETT


STATEMENT OF ADDITIONAL INFORMATION         JUNE 1, 1997


                          LORD ABBETT SECURITIES TRUST



This Statement of Additional  Information is not a Prospectus.  A Prospectus may
be obtained  from your  securities  dealer or from Lord Abbett  Distributor  LLC
("Lord Abbett  Distributor") at The General Motors  Building,  767 Fifth Avenue,
New York, New York 10153-0203.  This Statement relates to, and should be read in
conjunction with, the Prospectus dated June 1, 1997.

Lord Abbett  Securities  Trust (referred to as "we" or the "Fund") was organized
as a Delaware  business  trust on February  26,  1993.  The Fund has two series:
Growth & Income Series and the  International  Series (the "Series") each having
three classes of shares (A, B and C). All shares have equal noncumulative voting
rights and equal  rights  with  respect to  dividends,  assets and  liquidation,
except  for   certain   class-specific   expenses.   They  are  fully  paid  and
nonassessable when issued and have no preemptive or conversion rights.

Rule 18f-2  under the  Investment  Company Act of 1940,  as amended  (the "Act")
provides that any matter required to be submitted,  by the provisions of the Act
or applicable state law or otherwise,  to the holders of the outstanding  voting
securities of an investment company such as the Fund shall not be deemed to have
been effectively  acted upon unless approved by the holders of a majority of the
outstanding  shares of each class or series affected by such matter.  Rule 18f-2
further  provides  that a class or series  shall be deemed to be  affected  by a
matter  unless  the  interests  of  each  class  or  series  in the  matter  are
substantially identical or the matter does not affect any interest of such class
or series.  However,  the Rule  exempts  the  selection  of  independent  public
accountants,  the approval of principal  distributing contracts and the election
of trustees from its separate voting requirements.

Shareholder  inquiries  should  be made by  writing  directly  to the Fund or by
calling 800-821-5129. In addition, you can make inquiries through your dealer.

                        Investment Objective and Policies

FUNDAMENTAL INVESTMENT RESTRICTIONS
Both Series are subject to the following investment restrictions which cannot be
changed without approval of a majority of each Series'  outstanding shares. Each
Series may not:  (1) borrow  money,  except that (i) each Series may borrow from
banks (as  defined  in the Act ) in  amounts  up to 33 1/3% of its total  assets
(including the amount borrowed), (ii) each Series may borrow up to an additional
5% of its total assets for temporary purposes, (iii) each Series may obtain such
short-term  credit as may be necessary  for the clearance of purchases and sales
of portfolio  securities and (iv) each Series may purchase  securities on margin
to the extent  permitted by applicable law; (2) pledge its assets (other than to
secure  borrowings,  or to the  extent  permitted  by  each  Series'  investment
policies as permitted by  applicable  law);  (3) engage in the  underwriting  of
securities, except pursuant to a merger or acquisition or to the extent that, in
connection with the disposition of its portfolio securities, it may be deemed to
be an  underwriter  under  federal  securities  laws;  (4)  make  loans to other
persons,  except that the  acquisition of bonds,  debentures or other  corporate
debt  securities and  investment in government  obligations,  commercial  paper,
pass-through   instruments,   certificates  of  deposit,   bankers  acceptances,
repurchase  agreements or any similar  instruments  shall not be subject to this
limitation,  and  except  further  that  each  Series  may  lend  its  portfolio
securities,  provided that the lending of portfolio  securities may be made only
in accordance with applicable law; (5) buy or sell real estate (except that each
Series may invest in securities directly or indirectly secured by real estate or
interests  therein  or  issued  by  companies  which  invest  in real  estate or
interests therein),  or commodities or commodity contracts (except to the extent
each Series may do so in accordance with applicable law and without  registering
as a commodity pool operator  under the Commodity  Exchange Act as, for example,
with  futures  contracts);  (6) with  respect  to 75% of its gross  assets,  buy
securities  of one  issuer  representing  more than (i) 5% of its gross  assets,
except securities issued or guaranteed by the U.S.  Government,  its agencies or
instrumentalities  or (ii) 10% of the  voting  securities  of such  issuer;  (7)
invest more than 25% of its assets,  taken at market value, in the securities of
issuers in any particular industry (excluding securities of the U.S. Government,
its  agencies and  instrumentalities);  or (8) issue  senior  securities  to the
extent such issuance would violate applicable law.

With respect to the restrictions mentioned herein, compliance therewith will not
be affected by changes in the market value of portfolio  securities  but will be
determined at the time of purchase or sale of such securities.

NON-FUNDAMENTAL   INVESTMENT   RESTRICTIONS.   In  addition  to  the  investment
restrictions above which cannot be changed without  shareholder  approval,  each
Series  also is subject to the  following  non-fundamental  investment  policies
which may be changed by the Board of Trustees without shareholder approval. Each
Series may not:  (1) borrow in excess of 5% of its gross assets taken at cost or
market value,  whichever is lower at the time of  borrowing,  and then only as a
temporary measure for extraordinary or emergency purposes;  (2) make short sales
of securities  or maintain a short  position  except to the extent  permitted by
applicable  law;  (3) invest  knowingly  more than 15% of its net assets (at the
time of investment) in illiquid securities, except for securities qualifying for
resale under Rule 144A of the Securities Act of 1933, deemed to be liquid by the
Board of Trustees;  (4) invest in the securities of other  investment  companies
except as  permitted by  applicable  law;  (5) invest in  securities  of issuers
which,  with  their  predecessors,  have a  record  of less  than  three  years'
continuous  operations,  if more  than 5% of a  Series'  total  assets  would be
invested   in  such   securities   (this   restriction   shall   not   apply  to
mortgaged-backed  securities,  asset-backed  securities or obligations issued or
guaranteed by the U. S. government, its agencies or instrumentalities); (6) hold
securities of any issuer if more than 1/2 of 1% of the securities of such issuer
are owned beneficially by one or more officers or trustees of the Fund or by one
or more partners or members of the Fund's  underwriter or investment  adviser if
these owners in the aggregate own beneficially more than 5% of the securities of
such  issuer;  (7) invest in warrants  if, at the time of the  acquisition,  its
investment in warrants,  valued at the lower of cost or market,  would exceed 5%
of a Series' total assets (included within such limitation, but not to exceed 2%
of a Series' total assets,  are warrants which are not listed on the New York or
American Stock Exchange or a major foreign exchange);  (8) invest in real estate
limited partnership  interests or interests in oil, gas or other mineral leases,
or exploration or other development programs, except that each Series may invest
in  securities  issued by  companies  that engage in oil,  gas or other  mineral
exploration or other development  activities;  (9) write, purchase or sell puts,
calls,  straddles,  spreads  or  combinations  thereof,  except  to  the  extent
permitted in each Series' prospectus and statement of additional information, as
they may be  amended  from time to time;  or (10) buy from or sell to any of its
officers, trustees, employees, or its investment adviser or any of its officers,
trustees,  partners or employees, any securities other than shares of beneficial
interest in each Series. LENDING PORTFOLIO SECURITIES

Each Series may lend portfolio  securities to registered  broker-dealers.  These
loans,  if and when made, may not exceed 30% of each Series' total assets.  Each
Series  loan  of  securities  will  be  collateralized  by  cash  or  marketable
securities  issued or guaranteed by the U.S.  Government or its agencies  ("U.S.
Government  securities") or other permissible means at least equal to the market
value of the loaned securities. From time to time, each Series may pay a part of
the interest received with respect to the investment of collateral to a borrower
and/or a third  party  that is not  affiliated  with the Fund and is acting as a
"placing broker". No fee will be paid to affiliated persons of the Fund.

By  lending  portfolio  securities,  each  Series  can  increase  its  income by
continuing  to receive  interest on the loaned  securities  as well as by either
investing  the  cash  collateral  in  permissible  investments,   such  as  U.S.
Government  securities  or obtaining  yield in the form of interest  paid by the
borrower when U.S.  Government  securities or other forms of non-cash collateral
are received.  Each Series will comply with the following conditions whenever it
loans securities: (i) each Series must receive at least 100% collateral from the
borrower;  (ii) the borrower  must increase the  collateral  whenever the market
value of the securities  loaned rises above the level of the  collateral;  (iii)
each Series  must be able to  terminate  the loan at any time;  (iv) each Series
must receive  reasonable  compensation  for the loan, as well as any  dividends,
interest or other  distributions on the loaned  securities;  (v) each Series may
pay only  reasonable  fees in connection with the loan and (vi) voting rights on
the loaned  securities may pass to the borrower except that, if a material event
adversely affecting the investment in the loaned securities occurs, the Trustees
must terminate the loan and regain the right to vote the securities.

REPURCHASE AGREEMENTS

Each Series may enter into repurchase  agreements with respect to a security.  A
repurchase  agreement is a transaction by which each Series  acquires a security
and  simultaneously  commits to resell  that  security  to the seller (a bank or
securities  dealer) at an agreed upon price on an agreed  upon date.  The resale
price  reflects the  purchase  price plus an agreed upon market rate of interest
which is  unrelated  to the coupon  rate or date of  maturity  of the  purchased
security.  In this type of transaction,  the securities purchased by each Series
have a total  value in  excess of the value of the  repurchase  agreement.  Each
Series requires at all times that the repurchase  agreement be collateralized by
cash or U.S. Government securities having a value equal to, or in excess of, the
value of the repurchase  agreement.  Such agreements  permit each Series to keep
all of its assets at work while retaining  flexibility in pursuit of investments
of a longer term nature.

The use of repurchase  agreements  involves certain risks.  For example,  if the
seller of the agreement  defaults on its obligation to repurchase the underlying
securities  at a time  when the value of these  securities  has  declined,  each
Series may incur a loss upon disposition of them. If the seller of the agreement
becomes  insolvent  and  subject  to  liquidation  or  reorganization  under the
Bankruptcy  Code or other  laws,  a  bankruptcy  court  may  determine  that the
underlying  securities  are collateral not within the control of each Series and
are  therefore  subject to sale by the  trustee in  bankruptcy.  Even though the
repurchase  agreements may have  maturities of seven days or less, they may lack
liquidity,  especially if the issuer encounters  financial  difficulties.  While
Fund  management  acknowledges  these  risks,  it is  expected  that they can be
controlled   through  stringent   selection   criteria  and  careful  monitoring
procedures.   Fund  management   intends  to  limit  repurchase   agreements  to
transactions with dealers and financial institutions believed by Fund management
to present minimal credit risks.  Fund management will monitor  creditworthiness
of the repurchase agreement sellers on an ongoing basis.

The Series  will  enter  into  repurchase  agreements  only with  those  primary
reporting  dealers that report to the Federal  Reserve Bank of New York and with
the 100 largest United States  commercial  banks and the  underlying  securities
purchased  under the agreements  will consist only of those  securities in which
the Series otherwise may invest.

WARRANTS

Pursuant to Texas  regulations,  each Series will not invest more than 5% of its
assets in warrants  and not more than 2% of such value in warrants not listed on
the New York or  American  Stock  Exchanges,  except  when they form a unit with
other securities.  As a matter of operating policy, we will not invest more than
5% of our net assets in rights. COVERED CALL OPTIONS

As stated in the  Prospectus,  each Series may write  covered call options which
are traded on a national  securities  exchange with respect to securities in its
portfolio  in  an  attempt  to  increase  its  income  and  to  provide  greater
flexibility in the disposition of its portfolio securities. A "call option" is a
contract sold for a price (the  "premium")  giving its holder the right to buy a
specific  number of shares of stock at a  specific  price  prior to a  specified
date. A "covered  call  option" is a call option  issued on  securities  already
owned by the writer of the call  option  for  delivery  to the  holder  upon the
exercise of the option. During the period of the option, each Series forgoes the
opportunity  to profit from any increase in the market  price of the  underlying
security above the exercise price of the option (to the extent that the increase
exceeds  its  net  premium).  Each  Series  may  enter  into  "closing  purchase
transactions"  in order to terminate its  obligation  to deliver the  underlying
security  (this may result in a  short-term  gain or loss).  A closing  purchase
transaction  is the  purchase  of a call  option (at a cost which may be more or
less than the premium received for writing the original call option) on the same
security,  with the same exercise price and call period as the option previously
written. If a Series is unable to enter into a closing purchase transaction,  it
may be required to hold a security that it might  otherwise have sold to protect
against depreciation.  Neither Series intends to write covered call options with
respect to  securities  with an  aggregate  market  value of more than 5% of its
gross assets at the time an option is written.  This percentage  limitation will
not be increased without prior disclosure in the current Prospectus.

The Fund's custodian will segregate cash or liquid high-grade debt securities in
an amount not less than that required by Securities  Exchange Commission ("SEC")
Release  10666 with respect to Series assets  committed to written  covered call
options. If the value of the segregated securities declines,  additional cash or
debt securities will be added on a daily basis (i.e.,  marked-to-market) so that
the  segregated  amount  will  not be less  than  the  amount  of  each  Series'
commitments with respect to such written options.

OTHER  INTERNATIONAL  SERIES  INVESTMENT  POLICIES (WHICH CAN BE CHANGED WITHOUT
SHAREHOLDER APPROVAL)

FINANCIAL FUTURES CONTRACTS.  The International  Series may enter into contracts
for the future  delivery  of a financial  instrument,  such as a security or the
cash  value  of a  securities  index.  This  investment  technique  is  designed
primarily  to hedge  (i.e.,  protect)  against  anticipated  future  changes  in
interest rates or market  conditions  which otherwise might adversely affect the
value of securities  which we hold or intend to purchase.  A "sale" of a futures
contract  means the  undertaking  of a  contractual  obligation  to deliver  the
securities  or the cash  value  of an  index  called  for by the  contract  at a
specified price during a specified  delivery  period.  A "purchase" of a futures
contract  means the  undertaking  of a  contractual  obligation  to acquire  the
securities  or cash value of an index at a  specified  price  during a specified
delivery period. At the time of delivery  pursuant to the contract,  adjustments
are  made to  recognize  differences  in value  arising  from  the  delivery  of
securities  which differ from those  specified in the  contract.  In some cases,
securities called for by a futures contract may not have been issued at the time
the  contract  was  written.  The  International  Series will not enter into any
futures contracts or options on futures contracts if the aggregate of the market
value  of the  securities  covered  by its  outstanding  futures  contracts  and
securities  covered by futures  contracts  subject  to the  outstanding  options
written by it would exceed 50% of its total assets.

Although  some  financial  futures  contracts by their terms call for the actual
delivery or acquisition of securities, in most cases, a party will close out the
contractual  commitment  before delivery without having to make or take delivery
of the security by purchasing (or selling,  as the case may be) on a commodities
exchange an identical  futures  contract calling for delivery in the same month.
Such a  transaction,  if effected  through a member of an exchange,  cancels the
obligation to make or take delivery of the securities.  All  transactions in the
futures market are made, offset or fulfilled through a clearing house associated
with the exchange on which the contracts are traded.  The  International  Series
will incur  brokerage  fees when it  purchases  or sells  contracts  and will be
required  to  maintain  margin  deposits.  At the time it enters  into a futures
contract, it is required to deposit with its custodian, on behalf of the broker,
a specified amount of cash or eligible  securities  called "initial margin." The
initial margin  required for a futures  contract is set by the exchange on which
the contract is traded.  Subsequent payments,  called "variation margin," to and
from the broker are made on a daily  basis as the  market  price of the  futures
contract fluctuates.  The costs incurred in connection with futures transactions
could  reduce  the  Series'  return.  Futures  contracts  entail  risks.  If the
investment  adviser's  judgment about the general direction of interest rates or
markets  is  wrong,  the  overall  performance  may be  poorer  than  if no such
contracts had been entered into. There may be an imperfect  correlation  between
movements in prices of futures contracts and portfolio  securities being hedged.
The degree of difference in price movements  between  futures  contracts and the
securities  (or  securities  indices)  being hedged  depends upon such things as
variations  in demand  for  futures  contracts  and  securities  underlying  the
contracts  and  differences  between  the  liquidity  of the  markets  for  such
contracts and the securities underlying them. In addition,  the market prices of
futures contracts may be affected by certain factors not directly related to the
underlying securities. At any given time, the availability of futures contracts,
and  hence  their  prices,  are  influenced  by  credit  conditions  and  margin
requirements.  Due to the possibility of price distortions in the futures market
and because of the  imperfect  correlation  between  movements  in the prices of
securities and movements in the prices of futures contracts,  a correct forecast
of market  trends  by the  investment  adviser  may not  result in a  successful
hedging transaction.

OPTIONS ON FINANCIAL FUTURES  CONTRACTS.  The International  Series may purchase
and write call and put options on financial  futures  contracts.  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 at a specified  exercise price at any
time during the period of the option.  Upon  exercise,  the writer of the option
delivers  the  futures  contract  to the  holder  at  the  exercise  price.  The
International  Series  would be required to deposit with our  custodian  initial
margin and  maintenance  margin with  respect to put and call options on futures
contracts  written by us. Options on futures  contracts involve risks similar to
the risks relating to  transactions  in financial  futures  contracts  described
above. Generally speaking, a given dollar amount used to purchase an option on a
financial  futures  contract  can  hedge  a much  greater  value  of  underlying
securities than if that amount were used to directly purchase the same financial
futures.  Should the event that the  International  Series  intends to hedge (or
protect) against not materialize,  however, the option may expire worthless,  in
which case we would lose the premium paid therefor.

SEGREGATED  ACCOUNTS.  To the extent  required  to comply  with  Securities  and
Exchange Commission Release 10666 and any related SEC policies,  when purchasing
a futures  contract,  or writing a put  option,  the  International  Series will
maintain in a segregated account at its custodian bank cash, U.S. Government and
other permitted securities to cover its position.

<FN>

1. Outside  trustees'  fees,  including  attendance fees for board and committee
   meetings,  are allocated among all Lord  Abbett-sponsored  funds based on the
   net  assets of each fund.  A portion  of the fees  payable by the Fund to its
   outside  trustees  is being  deferred  under a plan that  deems the  deferred
   amounts to be  invested in shares of the Fund for later  distribution  to the
   trustees. The amounts of the aggregate compensation payable by the Fund as of
   April 30, 1997 deemed invested in Fund shares, including dividends reinvested
   and changes in net asset value applicable to such deemed  investments,  were:
   Mr. Bigelow,  $621; Mr. Dixon, $19,146; Mr. Jansing,  $19,639; Mr. MacDonald,
   $8,452; Mr. Millican,  $19,000 and Mr. Neff,  $19,849.  If the amounts deemed
   invested in Fund shares were added to each director's actual holdings of Fund
   shares as of April 30, 1997, each would own, the following:  Mr. Bigelow,  79
   shares;  Mr. Dixon,  2,845 shares;  Mr. Jansing,  6,564 shares; Mr. McDonald,
   1,077 shares; Mr. Millican, 2,420 shares; and Mr. Neff, 2,925 shares.

2. Each Lord  Abbett-sponsored fund has a retirement plan providing that outside
   trustees  may receive  annual  retirement  benefits for life equal to 100% of
   their final annual retainers following  retirement at or after age 72 with at
   least 10 years of service. Each plan also provides for a reduced benefit upon
   early retirement under certain circumstances,  a pre-retirement death benefit
   and actuarially reduced  joint-and-survivor spousal benefits. Such retirement
   plans, and the deferred  compensation plans referred to in footnote one, have
   been amended  recently to, among other  things,  enable  outside  trustees to
   elect to convert their  prospective  benefits under the  retirement  plans to
   equity-based  benefits  under the deferred  compensation  plans  (renamed the
   equity-based  plans and  hereinafter  referred  to as such).  Five of the six
   outside  trustees  made such an  election.  Mr.  Jansing did not. The amounts
   accrued in column 3 were accrued by the Lord  Abbett-sponsored  funds for the
   twelve months ended October 31, 1996 with respect to the equity-based  plans.
   These  accruals  were  based on the  plans as in  effect  before  the  recent
   amendments  and on the fees  payable to outside  trustees of the Fund for the
   twelve months ended October 31, 1996. Under the recent amendments, the annual
   retainer was  increased to $50,000 and the annual  retirement  benefits  were
   increased from 80% to 100% of a trustee's final annual retainer. Thus, if Mr.
   Jansing were to retire at or after age 72 and the annual retainer  payable by
   the  funds  were the same as it today,  he would  receive  annual  retirement
   benefits of $50,000.

3. This  column  shows  aggregate  compensation,  including  trustees  fees  and
   attendance fees for board and committee meetings,  of a nature referred to in
   footnote  one,  accrued by the Lord  Abbett-sponsored  funds  during the year
   ended December 31, 1996.

of whom are officers and/or trustees of the Fund, are: Stephen I. Allen, Zane E.
Brown,  Daniel E.  Carper,  Kenneth B. Cutler,  Robert S. Dow,  Daria L. Foster,
Robert G. Morris,  Robert J. Noelke,  E. Wayne  Nordberg and John J. Walsh.  The
address of each partner is The General Motors  Building,  767 Fifth Avenue,  New
York, New York 10153-0203.

The services  performed by Lord Abbett are described  under "Our  Management" in
the Prospectus.  Under the Management Agreement, each Series is obligated to pay
Lord Abbett a monthly fee, based on average daily net assets for each month,  at
the annual rate of .75 of 1%. This fee is allocated among Class A and C based on
the classes'  proportionate  shares of such daily net assets, in the case of the
Growth & Income  Series.  For the year ended October 31, 1996 such fees amounted
to $161,248  attributable to Class A and $339,410 attributable to Class C shares
of the Growth & Income Series.

Although not obligated to do so, Lord Abbett has waived or may waive all or part
of its  management  fees and has  assumed or may assume  other  expenses of each
Series. For the fiscal year ended October 31, 1996 Lord Abbett waived $242,341 ,
in management fees which were attributable to Class C shares, in the case of the
Growth & Income Series.

As  discussed  in  the  Prospectus  under  "Our   Management,"  each  Series  is
contingently obligated to repay to Lord Abbett the amounts of such assumed other
expenses.

Each Series pays all expenses not expressly  assumed by Lord Abbett,  including,
without  limitation,  12b-1  expenses,  outside  trustees'  fees  and  expenses,
association  membership  dues,  legal and  auditing  fees,  taxes,  transfer and
dividend disbursing agent fees,  shareholder  servicing costs, expenses relating
to  shareholder  meetings,  expenses of  preparing,  printing and mailing  stock
certificates and shareholder  reports,  expenses of registering our shares under
federal and state securities laws,  expenses of preparing,  printing and mailing
prospectuses to existing shareholders,  insurance premiums,  brokerage and other
expenses connected with executing portfolio transactions.

The Fund has agreed with the State of  California  to limit  operating  expenses
(including management fees but excluding taxes, interest, extraordinary expenses
and  brokerage  commissions)  to 2 1/2%  of  average  annual  net  assets  up to
$30,000,000, 2% of the next $70,000,000 of such assets and 1 1/2% of such assets
in excess of $100,000,000.  However, as described in the Prospectuses,  the Fund
has adopted a Plan pursuant to Rule 12b-1 of the Act for each class of shares of
the Series.  Annual Plan  distribution  expenses up to 1% of the Series' average
net assets during its fiscal year may be excluded from this expense  limitation.
The expense  limitation is a condition the  registration  of investment  company
shares for sale in the State and  applies  so long as our shares are  registered
for sale in that State.

Deloitte & Touche LLP, Two World Financial Center, New York, New York 10128, are
the  independent  public  accountants  of the Fund and must be approved at least
annually by our  trustees to  continue in such  capacity.  Deloitte & Touche LLP
perform  audit  services for the Fund  including  the  examination  of financial
statements included in our annual report to shareholders.

The Bank of New York ("BNY"),  48 Wall Street,  New York, New York 10286, is the
Fund's  custodian.  Rules adopted by the Securities & Exchange  Commission under
the Act permit the  International  Series to maintain its foreign  assets in the
custody of certain  eligible  foreign  banks and  securities  depositories.  The
International  Series'  portfolio  securities and cash, when invested in foreign
securities  and  not  held  by  BNY  or  its  foreign  branches,   are  held  by
sub-custodians  of BNY  approved  by the  Board  of  Trustees  of  the  Fund  in
accordance with such rules.

                             Portfolio Transactions

Our policy is to obtain best execution on all our portfolio transactions,  which
means that we seek to have purchases and sales of portfolio  securities executed
at the most favorable prices, considering all costs of the transaction including
brokerage  commissions  and dealer markups and markdowns and taking into account
the full range and quality of the brokers'  services.  Consistent with obtaining
best execution,  the Fund may pay, as described below, a higher  commission than
some  brokers  might  charge on the same  transaction.  This policy  governs the
selection  of  brokers or dealers  and the  market in which the  transaction  is
executed.  To the extent  permitted by law, we may, if considered  advantageous,
make a purchase from or sale to another Lord  Abbett-sponsored  fund without the
intervention of any broker-dealer.

Broker-dealers  are selected on the basis of their  professional  capability and
the value and quality of their brokerage and research  services.  Normally,  the
selection is made by traders who are officers of the Fund and also are employees
of Lord  Abbett.  These  traders do the  trading as well for other  accounts  --
investment  companies  (of which they are also  officers)  and other  investment
clients -- managed by Lord Abbett. For foreign  securities  purchased or sold by
the  International  Series,  the  selection  is  made  by the  Sub-Adviser.  The
Sub-Advisor are responsible for obtaining best execution.

In  transactions  on stock  exchanges  in the  United  States,  commissions  are
negotiated,  whereas on many foreign stock  exchanges  commissions are fixed. In
the case of  securities  traded in the  foreign  and  domestic  over-the-counter
markets, there is generally no stated commission, but the price usually includes
an undisclosed commission or markup. Purchases from underwriters of newly-issued
securities  for  inclusion  in the  Fund's  portfolios  usually  will  include a
concession  paid to the  underwriter  by the issuer and  purchases  from dealers
serving as market  makers  will  include  the spread  between  the bid and asked
prices.  When  commissions  are  negotiated,  we pay a  commission  rate that we
believe is appropriate  to give maximum  assurance that our brokers will provide
us, on a continuing  basis, the highest level of brokerage  services  available.
While we do not always seek the lowest possible commission on particular trades,
we pay a  commission  rate  that we  believe  is  appropriate  to  give  maximum
assurance that our brokers will provide us, on a continuing  basis,  the highest
level of brokerage  services  available.  While we do not always seek the lowest
possible  commissions on particular trades, we believe that our commission rates
are in line with the rates that many other  institutions  pay.  Our  traders are
authorized  to pay brokerage  commissions  in excess of those that other brokers
might  accept  on the  same  transactions  in  recognition  of the  value of the
services  performed  by the  executing  brokers,  viewed in terms of either  the
particular  transaction  or the  overall  responsibilities  of Lord  Abbett with
respect to us and the other accounts they manage.  Such services include showing
us trading  opportunities  including  blocks,  a willingness and ability to take
positions in securities,  knowledge of a particular  security or market,  proven
ability to handle a particular type of trade, confidential treatment, promptness
and reliability.

Some of our brokers  also provide  research  services at least some of which are
useful to Lord Abbett in their overall  responsibilities  with respect to us and
the other accounts they manage. Research includes the furnishing of analyses and
reports concerning issuers, industries, securities, economic factors and trends,
portfolio  strategy and the  performance  of accounts and trading  equipment and
computer software  packages,  acquired from third-party  suppliers,  that enable
Lord Abbett to access various  information  bases.  Such services may be used by
Lord Abbett in servicing all their  accounts,  and not all of such services will
necessarily  be used by Lord Abbett in connection  with their  management of the
Fund; conversely,  such services furnished in connection with brokerage on other
accounts  managed by Lord Abbett may be used in connection with their management
of the  Fund;  and not all of such  services  will  necessarily  be used by Lord
Abbett in connection  with their advisory  services to such other  accounts.  We
have been advised by Lord Abbett that  research  services  received from brokers
cannot be allocated to any  particular  account,  are not a substitute  for Lord
Abbett's  services but are  supplemental  to their own research effort and, when
utilized,  are subject to internal  analysis  before being  incorporated by Lord
Abbett into their investment  process.  As a practical  matter,  it would not be
possible for Lord Abbett to generate all of the information  presently  provided
by brokers.  While  receipt of research  services from  brokerage  firms has not
reduced Lord Abbett's  normal research  activities,  the expenses of Lord Abbett
could be  materially  increased  if it  attempted  to generate  such  additional
information  through its own staff and  purchased  such  equipment  and software
packages directly from the suppliers.

No commitments  are made  regarding the  allocation of brokerage  business to or
among brokers, and trades are executed only when they are dictated by investment
decisions of the Fund to purchase or sell portfolio securities.

If two or more  broker-dealers are considered capable of offering the equivalent
likelihood of best execution,  the  broker-dealer who has sold our shares and/or
shares of other Lord Abbett-sponsored funds may be preferred.

If other  clients of Lord Abbett buy or sell the same  security at the same time
as we do, transactions will, to the extent  practicable,  be allocated among all
participating  accounts  in  proportion  to the amount of each order and will be
executed  daily until filled so that each account  shares the average  price and
commission  cost of each day.  Other  clients  who direct  that their  brokerage
business be placed with  specific  brokers or who invest  through wrap  accounts
introduced to Lord Abbett by certain brokers may not participate  with us in the
buying and selling of the same  securities as described  above. If these clients
wish to buy or sell the same security as we do, they may have their transactions
executed at times different from our  transactions  and thus may not receive the
same price or incur the same commission cost as we do.

We will not seek  "reciprocal"  dealer  business  (for the  purpose of  applying
commissions  in whole or in part for our benefit or  otherwise)  from dealers as
consideration for the direction to them of portfolio business.

For the  period  January 3, 1994 to October  31,  1994 and for the fiscal  years
ended  October  31,  1995  and 1996 we paid  total  commissions  to  independent
broker-dealers of $15,489, $58,435 and $85,334.

                                       5.
                             Purchases, Redemptions
                            and Shareholder Services

Securities in the Fund's  portfolios are valued at their market values as of the
close of the NYSE. Market value will be determined as follows: securities listed
or admitted to trading privileges on any national or foreign securities exchange
are valued at the last sales price on the principal securities exchange on which
such  securities  are traded,  or, if there is no sale,  at the mean between the
last bid and asked  prices on such  exchange,  or, in the case of bonds,  in the
over-the-counter  market if, in the judgment of the Fund's officers, that market
more accurately  reflects the market value of the bonds.  Securities traded only
in the over-the-counter  market are valued at the mean between the bid and asked
prices, except that securities admitted to trading on the NASDAQ National Market
System  are  valued  at the  last  sales  price.  Securities  for  which  market
quotations are not available are valued at fair value under procedures  approved
by the Board of Trustees.

All assets and  liabilities  expressed in foreign  currencies  will be converted
into United  States  dollars at the mean between the buying and selling rates of
such currencies  against United States dollars last quoted by any major bank. If
such  quotations are not  available,  the rate of exchange will be determined in
accordance with policies established by the Fund's Board of Trustees.  The Board
of Trustees will monitor, on an ongoing basis, the Fund's method of valuation.

Information  concerning  how we value our Shares for the purchase and redemption
of  our  Shares  is  described  in  the   Prospectus   under   "Purchases"   and
"Redemptions", respectively.

As  disclosed  in the  Prospectus,  we  calculate  our net asset  values and are
otherwise  open for business on each day that the NYSE is open for trading.  The
NYSE is closed on Saturdays and Sundays and the following holidays -- New Year's
Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving and Christmas.

The net asset value per share for the Class A shares will be  determined  in the
same  manner  as for the  Class B and C shares  (net  assets  divided  by shares
outstanding).  Our Class A shares will be sold with a front-end  sales charge of
5.75%.

The maximum  offering  prices of each Series' Class A shares on October 31, 1996
were computed as follows:

                                           Growth & Income         International
                                              SERIES                 SERIES
Net asset value per share (net assets
  divided by shares outstanding................$7.09                $9.425

Maximum offering price per
  share (net asset value divided by
 .9425 in both cases) .........................$7.52                $10.00

The  offering  price of Class C shares of the Growth & Income  Series on October
31, 1996 was computed as follows:

  Net asset value per share (net assets divided by
    shares outstanding) . . . . . . . . . . . .$7.09                $9.425

The Fund has entered into a distribution  agreement with Lord Abbett Distributor
LLC, a New York limited  liability  company ("Lord Abbett  Distributor"),  under
which Lord  Abbett  Distributor  is  obligated  to use its best  efforts to find
purchasers  for the shares of the Fund, and to make  reasonable  efforts to sell
Fund shares so long as, in Lord Abbett  Distributor's  judgment,  a  substantial
distribution can be obtained by reasonable efforts.

Conversion  of Class B Shares.  The  conversion  of Class B shares on the eighth
anniversary  of their purchase is subject to the  continuing  availability  of a
private  letter  ruling  from the  Internal  Revenue  Service,  or an opinion of
counsel or tax adviser, to the effect that the conversion of Class B shares does
not  constitute a taxable event for the holder under Federal  income tax law. If
such  a  revenue  ruling  or  opinion  is no  longer  available,  the  automatic
conversion  feature may be suspended,  in which event no further  conversions of
Class B shares would occur while such  suspension  remained in effect.  Although
Class B shares  could  then be  exchanged  for  Class A shares  on the  basis of
relative net asset value of the two classes,  without the  imposition of a sales
charge or fee, such exchange could constitute a taxable event for the holder.

CLASS A, B AND C RULE 12B-1 PLANS. As described in the Prospectus,  the Fund has
adopted a Distribution  Plan and Agreement on behalf of each Series  pursuant to
Rule  12b-1 of the Act for each  class of  shares  available  in the  applicable
series: the "A Plan", the "B Plan" and the "C Plan",  respectively.  In adopting
each Plan and in approving its continuance,  the Board of Trustees has concluded
that there is a reasonable likelihood that each Plan will benefit its respective
Class and such Class' shareholders.  The expected benefits include greater sales
and lower redemptions of Class shares, which should allow each Class to maintain
a  consistent  cash flow,  and a higher  quality of service to  shareholders  by
authorized institutions than would otherwise be the case. During the last fiscal
year,  the  Growth & Income  Series  accrued  or paid  through  Lord  Abbett  to
authorized  institutions $28,799 under the A Plan and $490,573 under the C Plan.
The A Plan for the  International  Series  became  effective  subsequent  to the
Fund's last fiscal year. Lord Abbett used all amounts received under the A and C
Plans for the Growth & Income  Series for payments to dealers for (i)  providing
continuous services to the Class A shareholders,  such as answering  shareholder
inquiries,   maintaining   records,   and  assisting   shareholders   in  making
redemptions,  transfers,  additional  purchases  and  exchanges  and (ii)  their
assistance in distributing Class A shares of the Fund.

Each Plan requires the trustees to review, on a quarterly basis, written reports
of all amounts  expended  pursuant to the Plan and the  purposes  for which such
expenditures  were  made.  Each  Plan  shall  continue  in  effect  only  if its
continuance is specifically  approved at least annually by vote of the trustees,
including a majority of the trustees who are not interested  persons of the Fund
and who have no direct or indirect  financial  interest in the  operation of the
Plan or in any  agreements  related to the Plan  ("outside  trustees"),  cast in
person at a meeting called for the purpose of voting on the Plan. No Plan may be
amended to  increase  materially  above the limits set forth  therein the amount
spent for distribution expenses thereunder without approval by a majority of the
outstanding  voting  securities  of the  applicable  class and the approval of a
majority of the  trustees,  including a majority of the outside  trustees.  Each
Plan may be terminated at any time by vote of a majority of the outside trustees
or by vote of a majority of its Class's outstanding voting securities.

CONTINGENT  DEFERRED SALES CHARGES. A Contingent Deferred Sales Charge ("CDSC"),
applies upon early  redemption of shares  regardless  of class,  and (i) will be
assessed  on the  lesser  of the net  asset  value of the  shares at the time of
redemption  or the original  purchase  price and (ii) will not be imposed on the
amount of your account value represented by the increase in net asset value over
the initial  purchase  price  (including  increases due to the  reinvestment  of
dividends and capital gains distributions) and upon early redemption of shares.

CLASS A SHARES.  As  stated  in the  Prospectus,  a CDSC of 1% is  imposed  with
respect  to  those   Class  A  shares  (or  Class  A  shares  of  another   Lord
Abbett-sponsored  fund or series  acquired  through  exchange of such shares) on
which a Series has paid the one-time  distribution  fee of 1% if such shares are
redeemed out of the Lord Abbett-sponsored  family of funds within a period of 24
months from the end of the month in which the original sale occurred.

CLASS B  SHARES.  As  stated in the  Prospectus,  if Class B shares  (or Class B
shares of another Lord Abbett-sponsored fund or series acquired through exchange
of such shares) are redeemed  out of the Lord  Abbett-sponsored  family of funds
for cash before the sixth anniversary of their purchase, a CDSC will be deducted
from  the  redemption  proceeds.  The  Class  B CDSC  is  paid  to  Lord  Abbett
Distributor  to  reimburse  its  expenses,  in whole or in part,  for  providing
distribution-related service in connection with the sale of Class B shares.

To determine whether the CDSC applies to a redemption, the Series redeems shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends and
capital gains  distributions,  (2) shares held on or after the sixth anniversary
of  their  purchase,   and  (3)  shares  held  the  longest  before  such  sixth
anniversary.

The amount of the contingent  deferred sales charge will depend on the number of
years since you invested and the dollar amount being redeemed,  according to the
following schedule:

Anniversary of the Day on                      Contingent Deferred Sales Charge
Which the Purchase Order Was Accepted          on Redemptions (As % of Amount 
                                               Subject to Charge)
Before the 1st.....................................................5.0%
On the 1st, before the 2nd.........................................4.0%
On the 2nd, before the 3rd.........................................3.0%
On the 3rd, before the 4th.........................................3.0%
On the 4th, before the 5th.........................................2.0%
On the 5th, before the 6th ........................................1.0%
On or after the 6th anniversary........................................None

In the table, an  "anniversary" is the 365th day subsequent to the acceptance of
a purchase  order or a prior  anniversary.  All purchases are considered to have
been made on the business day on which the purchase order was accepted.

CLASS C SHARES. As stated in the Prospectus,  if Class C shares are redeemed for
cash before the first anniversary of their purchase,  the redeeming  shareholder
will be  required  to pay to the Series on behalf of Class C shares a CDSC of 1%
of the lower of cost or the then net asset value of Class C shares redeemed.  If
such shares are exchanged  into the same class of another Lord  Abbett-sponsored
fund and  subsequently  redeemed before the first  anniversary of their original
purchase,  the  charge  will be  collected  by the other  fund on behalf of this
Series' Class C shares.

GENERAL.  Each percentage (1% in the case of Class A and C shares and 5% through
1% in the case of Class B shares) used to calculate  CDSCs  described  above for
the Class A, Class B and Class C shares is sometimes  hereinafter referred to as
the "Applicable Percentage".

With respect to Class A and Class B shares, no CDSC is payable on redemptions by
participants or beneficiaries from employer-sponsored retirement plans under the
Internal  Revenue  Code  for  benefit  payments  due  to  plan  loans,  hardship
withdrawals,  death,  retirement or  separation  from service and for returns of
excess  contributions  to retirement  plan sponsors.  In the case of Class A and
Class C shares, the CDSC is received by the applicable Series and is intended to
reimburse  all or a portion of the  amount  paid by the Series if the shares are
redeemed  before the Series has had an  opportunity  to realize the  anticipated
benefits of having a long-term shareholder account in the Series. In the case of
Class B shares,  the CDSC is received by Lord Abbett Distributor and is intended
to  reimburse  its  expenses of  providing  distribution-related  service to the
applicable  Series  (including  recoupment of the  commission  payments made) in
connection  with the sale of Class B shares before Lord Abbett  Distributor  has
had an opportunity  to realize its  anticipated  reimbursement  by having such a
long-term  shareholder account subject to the B Plan distribution fee. The other
funds and series which participate in the Telephone  Exchange  Privilege (except
(a) Lord Abbett U.S.  Government  Securities Money Market Fund, Inc.  ("GSMMF"),
(b) certain series of Lord Abbett  Tax-Free Income Fund and Lord Abbett Tax-Free
Income  Trust  for which a Rule  12b-1  Plan is not yet in  effect,  and (c) any
authorized  institution's  affiliated  money market fund  satisfying Lord Abbett
Distributor  as to  certain  omnibus  account  and other  criteria,  hereinafter
referred to as an "authorized  money market fund" or "AMMF"  (collectively,  the
"Non-12b-1  Funds")) have instituted a CDSC for each class on the same terms and
conditions.  No CDSC will be charged on an  exchange of shares of the same class
between  Lord Abbett funds or between such funds and AMMF.  Upon  redemption  of
shares out of the Lord Abbett  family of funds or out of AMMF,  the CDSC will be
charged on behalf of and paid:  (i) to the fund in which the  original  purchase
(subject to a CDSC) occurred,  in the case of the Class A and Class C shares and
(ii) to Lord Abbett  Distributor if the original purchase was subject to a CDSC,
in the case of the Class B shares.  Thus,  if shares of a Lord  Abbett  fund are
exchanged  for shares of the same  class of another  such fund and the shares of
the same class  tendered  ("Exchanged  Shares") are subject to a CDSC,  the CDSC
will carry over to the shares of the same class being acquired,  including GSMMF
and AMMF ("Acquired  Shares").  Any CDSC that is carried over to Acquired Shares
is calculated as if the holder of the Acquired Shares had held those shares from
the date on which he or she became the holder of the Exchanged Shares.  Although
the Non-12b-1  Funds will not pay a  distribution  fee on their own shares,  and
will, therefore, not impose their own CDSC, the Non-12b-1 Funds will collect the
CDSC (a) on behalf of other Lord  Abbett  funds,  in the case of the Class A and
Class C shares and (b) on behalf of Lord Abbett Distributor,  in the case of the
Class B shares.  Acquired  Shares  held in GSMMF and AMMF which are subject to a
CDSC will be  credited  with the time such shares are held in GSMMF but will not
be  credited  with the time such  shares  are held in AMMF.  Therefore,  if your
Acquired  Shares  held in  AMMF  qualified  for no  CDSC  or a lower  Applicable
Percentage at the time of exchange into AMMF,  that  Applicable  Percentage will
apply to  redemptions  for cash from AMMF,  regardless of the time you have held
Acquired Shares in AMMF.

In no event will the amount of the CDSC exceed the Applicable  Percentage of the
lesser of (i) the net asset value of the shares  redeemed  or (ii) the  original
cost of such  shares (or of the  Exchanged  Shares for which  such  shares  were
acquired). No CDSC will be imposed when the investor redeems (i) amounts derived
from  increases in the value of the account above the total cost of shares being
redeemed due to increases in net asset value,  (ii) shares with respect to which
no Lord Abbett  fund paid a 12b-1 fee and,  in the case of Class B shares,  Lord
Abbett  Distributor  paid no sales  charge  or  service  fee  (including  shares
acquired   through   reinvestment   of  dividend   income  and   capital   gains
distributions) or (iii) shares which,  together with Exchanged Shares, have been
held  continuously for 24 months from the end of the month in which the original
sale  occurred  (in the case of Class A  shares);  for six years or more (in the
case  of  Class B  shares)  and for one  year or more  (in the  case of  Class C
shares). In determining whether a CDSC is payable, (a) shares not subject to the
CDSC will be redeemed  before  shares  subject to the CDSC and (b) of the shares
subject to a CDSC, those held the longest will be the first to be redeemed.

EXCHANGES.  The Prospectus briefly describes the Telephone  Exchange  Privilege.
You may  exchange  some or all of your shares of any class for those in the same
class of: (i) Lord Abbett-sponsored funds currently offered to the public with a
sales charge  (front-end,  back-end or level ), (ii) GSMMF or (iii) AMMF, to the
extent  offers  and  sales  may be made in  your  state.  You  should  read  the
prospectus of the other fund before exchanging. In establishing a new account by
exchange, shares of the Fund being exchanged must have a value equal to at least
the  minimum  initial  investment  required  for the other  fund into  which the
exchange is made.

Shareholders in other Lord  Abbett-sponsored  funds and AMMF have the same right
to  exchange  their  shares for the  corresponding  class of the Fund's  shares.
Exchanges  are based on relative  net asset values on the day  instructions  are
received by the Fund in Kansas City if the  instructions  are received  prior to
the close of the NYSE in proper form. No sales charges are imposed except in the
case of  exchanges  out of  GSMMF or AMMF  (unless  a sales  charge  (front-end,
back-end or level) was paid on the initial investment in a Lord Abbett-sponsored
fund).  Exercise of the exchange privilege will be treated as a sale for federal
income tax purposes, and, depending on the circumstances,  a gain or loss may be
recognized. In the case of an exchange of shares that have been held for 90 days
or less where no sales charge is payable on the  exchange,  the  original  sales
charge incurred with respect to the exchanged  shares will be taken into account
in  determining  gain or loss on the  exchange  only to the extent  such  charge
exceeds the sales charge that would have been payable on the acquired shares had
they been acquired for cash rather than by exchange. The portion of the original
sales charge not so taken into  account will  increase the basis of the acquired
shares.

Shareholders have the exchange  privilege unless they refuse it in writing.  You
should  not view the  exchange  privilege  as a means for  taking  advantage  of
short-term swings in the market,  and we reserve the right to terminate or limit
the privilege of any shareholder who makes frequent exchanges.  We can revoke or
modify the privilege for all shareholders upon 60 days' prior notice.  "Eligible
Funds" are AMMF and other Lord Abbett-sponsored funds which are eligible for the
exchange  privilege,  except Lord Abbett Series Fund  ("LASF")  which offers its
shares only in connection with certain variable annuity  contracts,  Lord Abbett
Equity  Fund  ("LAEF")  which is not issuing  shares,  and series of Lord Abbett
Research Fund not offered to the general public ("LARF").

STATEMENT OF INTENTION.  Under the terms of the Statement of Intention to invest
$50,000 or more over a 13-month period as described in the Prospectus, shares of
a Lord  Abbett-sponsored  fund (other than shares of LAEF, LASF, LARF, GSMMF and
AMMF,  unless holdings in GSMMF and AMMF are  attributable  to shares  exchanged
from a Lord  Abbett-sponsored  fund offered with a front-end,  back-end or level
sales charge) currently owned by you are credited as purchases (at their current
offering prices on the date the Statement is signed) toward achieving the stated
investment and reduced  initial sales charge for Class A shares.  Class A shares
valued  at 5% of the  amount  of  intended  purchases  are  escrowed  and may be
redeemed to cover the  additional  sales charge  payable if the Statement is not
completed.  The Statement of Intention is neither a binding obligation on you to
buy, nor on the Fund to sell, the full amount indicated.

RIGHTS OF ACCUMULATION.  As stated in the Prospectus,  purchasers (as defined in
the Prospectus) may accumulate their investment in Lord  Abbett-sponsored  funds
(other than LAEF, LARF,  LASF,  GSMMF, and AMMF unless holdings in GSMMF or AMMF
are attributable to shares exchanged from a Lord  Abbett-sponsored  fund offered
with a front-end,  back-end or level sales charge) so that a current investment,
plus the  purchaser's  holdings  valued at the current  maximum  offering price,
reach a level eligible for a discounted sales charge for Class A shares.

NET ASSET VALUE PURCHASES OF CLASS A SHARES.  As stated in the  Prospectus,  our
Class A shares may be purchased at net asset value by our  directors,  employees
of Lord Abbett,  employees of our  shareholder  servicing agent and employees of
any securities  dealer having a sales agreement with Lord Abbett who consents to
such   purchases  or  by  the  director  or  custodian   under  any  pension  or
profit-sharing plan or Payroll Deduction IRA established for the benefit of such
persons  or for the  benefit  of  employees  of any  national  securities  trade
organization  to which Lord Abbett  belongs or any company with an account(s) in
excess of $10  million  managed  by Lord  Abbett  on a  private-advisory-account
basis.  For purposes of this  paragraph,  the terms  "directors" and "employees"
include a director's or employee's  spouse  (including the surviving spouse of a
deceased director or employee). The terms "our directors" and "employees of Lord
Abbett" also include  retired  directors and employees and other family  members
thereof.

Our Class A shares also may be purchased at net asset value (a) at $1 million or
more,  (b) with  dividends and  distributions  from Class A shares of other Lord
Abbett-sponsored  funds,  except  for LARF,  LAEF and  LASF,  (c) under the loan
feature of the Lord  Abbett-sponsored  prototype 403(b) plan for share purchases
representing the repayment of principal and interest,  (d) by certain authorized
brokers, dealers, registered investment advisers or other financial institutions
who have entered into an agreement  with Lord Abbett  Distributor  in accordance
with  certain  standards   approved  by  Lord  Abbett   Distributor,   providing
specifically  for the use of our shares in particular  investment  products made
available for a fee to clients of such brokers,  dealers,  registered investment
advisers and other financial institutions, ("mutual fund wrap fee program"), (e)
by employees,  partners and owners of  unaffiliated  consultants and advisors to
Lord Abbett, Lord Abbett Distributor or Lord Abbett-sponsored  funds who consent
to such  purchase if such persons  provide  service to Lord Abbett,  Lord Abbett
Distributor or such funds on a continuing basis and are familiar with such funds
and (f) through Retirement Plans with at least 100 eligible employees.

REDEMPTIONS.  A  redemption  order is in proper form when it contains all of the
information and  documentation  required by the order form or  supplementally by
Lord Abbett Distributor or the Fund to carry out the order. The signature(s) and
any legal capacity of the signer(s) must be guaranteed by an eligible guarantor.
See the Prospectus for expedited redemption procedures.

The right to redeem and receive payment, as described in the Prospectus,  may be
suspended if the NYSE is closed  (except for  weekends or  customary  holidays),
trading on the NYSE is  restricted  or the  Securities  and Exchange  Commission
deems an emergency to exist.

Our Board of  Trustees  may  authorize  redemption  of all of the  shares in any
account  in which  there are  fewer  than 60  shares.  Before  authorizing  such
redemption, the Board must determine that it is in our economic best interest or
necessary  to  reduce   disproportionately   burdensome  expenses  in  servicing
shareholder  accounts.  At least 6 months  prior  written  notice  will be given
before any such redemption,  during which time shareholders may avoid redemption
by bringing their accounts up to the minimum set by the Board.

DIV-MOVE. Under the Div-Move service described in the Prospectus, you can invest
the dividends paid on your account of any class into an existing  account of the
same class in any other  Eligible Fund. The account must be either your account,
a joint account for you and your spouse, a single account for your spouse,  or a
custodial  account for your minor child under the age of 21. You should read the
prospectus of the other fund before investing.

INVEST-A-MATIC.  The  Invest-A-Matic  method of investing in the Fund and/or any
other  Eligible Fund is described in the  Prospectus.  To avail yourself of this
method you must complete the application form,  selecting the time and amount of
your bank checking account  withdrawals and the funds for investment,  include a
voided, unsigned check and complete the bank authorization.

SYSTEMATIC  WITHDRAWAL  PLANS.  The Systematic  Withdrawal  Plan ("SWP") also is
described  in the  Prospectus.  You may  establish  a SWP if you own or purchase
uncertificated shares having a current offering price value of at least $10,000.
Lord Abbett prototype  retirement plans have no such minimum.  With respect to a
SWP for Class B shares, on redemptions over 12% per year, the CDSC will apply to
the entire  redemption.  Therefore,  please  contact the Fund for  assistance in
minimizing the CDSC in this situation.  With respect to Class C shares, the CDSC
will be waived on and after the first  anniversary  of their  purchase.  The SWP
involves  the  planned  redemption  of shares on a periodic  basis by  receiving
either  fixed or  variable  amounts at  periodic  intervals.  Since the value of
shares  redeemed  may be more or  less  than  their  cost,  gain or loss  may be
recognized for income tax purposes on each periodic payment.  Normally,  you may
not make  regular  investments  at the same  time you are  receiving  systematic
withdrawal  payments because it is not in your interest to pay a sales charge on
new  investments  when in  effect  a  portion  of that  new  investment  is soon
withdrawn.  The minimum investment accepted while a withdrawal plan is in effect
is  $1,000.  The SWP may be  terminated  by you or by us at any time by  written
notice.

RETIREMENT  PLANS.  The Prospectus  indicates the types of retirement  plans for
which Lord Abbett provides forms and  explanations.  Lord Abbett makes available
the  retirement  plan  forms  and  custodial  agreements  for  IRAs  (Individual
Retirement  Accounts,  including Simple IRAs and Simplified  Employee Pensions),
403(b) plans and qualified pension and  profit-sharing  plans,  including 401(k)
plans. The forms name Investors Fiduciary Trust Company as custodian and contain
specific   information   about  the  plans.   Explanations  of  the  eligibility
requirements,  annual  custodial fees and allowable tax advantages and penalties
are set forth in the  relevant  plan  documents.  Adoption of any of these plans
should be on the advice of your legal counsel or qualified tax adviser.

                                Past Performance

Each Series computes the average annual compounded rate of total return for each
Class during specified  periods that would equate the initial amount invested to
the ending  redeemable  value of such  investment  by adding one to the computed
average  annual total return,  raising the sum to a power equal to the number of
years covered by the computation  and  multiplying  the result by $1,000,  which
represents a hypothetical initial investment.  The calculation assumes deduction
of the maximum sales charge (as described in the next paragraph) from the amount
invested  and   reinvestment   of  all  income   dividends   and  capital  gains
distributions  on  the  reinvestment  dates  at  net  asset  value.  The  ending
redeemable  value is determined by assuming a complete  redemption at the end of
the period(s) covered by the average annual total return computation.

In  calculating  total  returns for Class A shares,  the current  maximum  sales
charge of 5.75% (as a  percentage  of the offering  price) is deducted  from the
initial  investment (unless the return is shown at net asset value). For Class B
shares,  the payment of the applicable CDSC (5.0% prior to the first anniversary
of purchase, 4.0% prior to the second anniversary of purchase, 3.0% prior to the
third and fourth anniversaries of purchase,  2.0% prior to the fifth anniversary
of purchase,  1.0% prior to the sixth anniversary of purchase and no CDSC on and
after the sixth  anniversary  of purchase) is applied to the Series'  investment
result for that class for the time  period  shown  (unless  the total  return is
shown at net asset value).  For Class C shares,  the 1.0% CDSC is applied to the
applicable  Series'  investment  result for that class for the time period shown
prior to the first  anniversary of purchase (unless the total return is shown at
net asset value). Total returns also assume that all dividends and capital gains
distributions during the period are reinvested at net asset value per share, and
that the investment is redeemed at the end of the period.

Using  the  method  described  above  for the  period  beginning  July 15,  1996
(commencement  date of Class A shares)  to October  31,  1996 the rate for total
return for the Growth & Income Series was 5.60 % (not  annualized) for the Class
A shares and for the fiscal-year ending on October 31, 1996 was 20.10% the Class
C shares.

Each Series' yield quotation for each class is based on a 30-day period ended on
a specified  date,  computed by dividing such Series' net investment  income per
share earned during the period by such Series' maximum  offering price per share
on the last day of the  period.  This is  determined  by finding  the  following
quotient:  take the Class' dividends and interest earned during the period minus
its expenses accrued for the period and divide by the product of (i) the average
daily number of Class shares outstanding during the period that were entitled to
receive  dividends and (ii) the Series' maximum  offering price per share on the
last day of the period.  To this  quotient add one.  This sum is  multiplied  by
itself  five  times.   Then  one  is   subtracted   from  the  product  of  this
multiplication  and the remainder is  multiplied  by two.  Yield for the Class A
shares reflects the deduction of the maximum initial sales charge,  but may also
be shown based on the Series' net asset value per share.  Yields for Class B and
Class C shares do not reflect the deduction of the CDSC.

These figures represent past  performance,  and an investor should be aware that
the investment return and principal value of a Fund investment will fluctuate so
that an investor's shares,  when redeemed,  may be worth more or less than their
original cost.  Therefore,  there is no assurance that this  performance will be
repeated in the future.

                                       7.
                                      Taxes

The value of any shares  redeemed by the Fund or  repurchased  or otherwise sold
may be  more  or less  than  your  tax  basis  in the  shares  at the  time  the
redemption,  repurchase  or sale is made.  Any gain or loss  will  generally  be
taxable  for  federal  income  tax  purposes.  Any loss  realized  on the  sale,
redemption  or  repurchase  of Fund shares which you have held for six months or
less will be treated for tax purposes as a long-term  capital loss to the extent
of any capital  gains  distributions  which you  received  with  respect to such
shares.  Losses on the sale of stock or securities are not deductible if, within
a period  beginning 30 days before the date of the sale and ending 30 days after
the  date of the  sale,  the  taxpayer  acquires  stock or  securities  that are
substantially identical.

The writing of call options and other investment  techniques and practices which
the Fund may  utilize,  as  described  above under  "Investment  Objectives  and
Policies," may create  "straddles" for United States federal income tax purposes
and may affect the character and timing of the  recognition  of gains and losses
by the Fund.  Such  transactions  may increase the amount of short-term  capital
gain realized by the Fund, which is taxed as ordinary income when distributed to
shareholders.  Limitations  imposed by the  Internal  Revenue  Code on regulated
investment  companies may restrict the Fund's ability to engage in  transactions
in options.

The Fund will be subject to a 4%  non-deductible  excise tax on certain  amounts
not distributed  (and not treated as having been  distributed) on a timely basis
in accordance with a calendar-year distribution requirement. The Fund intends to
distribute to shareholders  each year an amount adequate to avoid the imposition
of  such  excise  tax.   Dividends  paid  by  the  Fund  will  qualify  for  the
dividends-received  deduction  for  corporations  to the extent they are derived
from dividends paid by domestic corporations.

The  foregoing  discussion  relates  solely to U.S.  federal  income  tax law as
applicable to United States  persons  (United  States  citizens or residents and
United States  domestic  corporations,  partnerships,  trusts and estates.) Each
shareholder  who is not a United States  person  should  consult his tax adviser
regarding  the U.S. and foreign tax  consequences  of the ownership of shares of
the Fund,  including a 30% (or lower treaty rate) United States  withholding tax
on dividends  representing ordinary income and net short-term capital gains, and
the  applicability  of United States gift and estate taxes to non-United  States
persons who own Fund shares.

                                       8.
                           Information About the Fund

Shareholder  Liability.  Delaware law provides that Fund  shareholders  shall be
entitled to the same limitations of personal  liability extended to stockholders
of private  corporations  for profit.  The courts of some states,  however,  may
decline to apply  Delaware law on this point.  The Fund's  Declaration  of Trust
contains  an  express   disclaimer  of  shareholder   liability  for  the  acts,
obligations,  or affairs of the Fund and requires  that a disclaimer be given in
each contract entered into or executed by the Fund. The Declaration provides for
indemnification  out  of  the  Fund's  property  of any  shareholder  or  former
shareholder  held personally  liable for the obligations of the Fund.  Thus, the
risk of a  shareholder  incurring  financial  loss  on  account  of  shareholder
liability is limited to  circumstances  in which Delaware law does not apply, no
contractual limitation of liability was in effect and the portfolio is unable to
meet its obligations.  Lord Abbett believes that, in view of the above, the risk
of personal liability to shareholders is extremely remote.

Under The Fund's  Declaration of Trust,  the trustees may,  without  shareholder
vote,  cause the Fund to merge or  consolidate  into,  or sell and convey all or
substantially all of, the assets of the Fund to one or more trusts, partnerships
or  corporations,  so long as the  surviving  entity is an  open-end  management
investment  company  that will  succeed  to or assume  the  Fund's  registration
statement.  In addition,  the trustees may, without  shareholder vote, cause the
Fund to be incorporated under Delaware law.

Derivative  actions  on behalf of the Fund may be brought  only by  shareholders
owning not less than 50% of the then outstanding shares of the Fund.

The  directors,  trustees and officers of Lord  Abbett-sponsored  mutual  funds,
together  with the partners  and  employees  of Lord  Abbett,  are  permitted to
purchase and sell securities for their personal  investment account. In engaging
in  personal  securities  transactions,  however,  such  persons  are subject to
requirements  and  restrictions  contained  in the Trust's  Code of Ethics which
complies,  in  substance,  with each of the  recommendations  of the  Investment
Company Institute's  Advisory Group on Personal  Investing.  Among other things,
the Code  requires  that Lord  Abbett  partners  and  employees  obtain  advance
approval before buying or selling securities, submit confirmations and quarterly
transaction  reports,  and obtain  approval  before  becoming a director  of any
company;  and it prohibits  such persons from investing in a security seven days
before  or  after  any  Lord  Abbett-sponsored  fund  trades  in such  security,
profiting  from  trades  of the same  security  within  60 days and  trading  on
material  non-public  information.  The Code imposes  similar  requirements  and
restrictions on the independent trustees of the Trust to the extent contemplated
by the recommendations of such Advisory Group.

Notes to Financial Statements


1. Significant Accounting Policies

Lord Abbett Securities Trust (the "Trust") is an open-end management  investment
company,  organized as a Delaware business trust on February 26, 1993. The Trust
currently consists of two separate  portfolios  ("Series")-Lord  Abbett Growth &
Income  Series  ("Growth  &  Income")  and  Lord  Abbett   International  Series
("International").  Effective  December 10, 1996, The  International  Series was
added  on  December  10,  1996 at  which  time  the  Trust  received  a  capital
contribution of $2,000,000 and issued 212,202 shares of the International Series
to  the  partners  of  Lord,  Abbett  & Co.  ("Lord  Abbett").  Each  Series  is
diversified as defined under the  Investment  Company Act of 1940. The financial
statements have been prepared in conformity with generally  accepted  accounting
principles which permit  management to make certain estimates and assumptions at
the date of the financial  statements.  The following summarizes the significant
accounting  policies of the Trust:  (a) Market value is  determined  as follows:
Securities listed or admitted to trading  privileges on any national  securities
exchange are valued at the last sales price on the principal securities exchange
on which  such  securities  are  traded,  or,  if there is no sale,  at the mean
between the last bid and asked prices on such exchange. Securities traded in the
over-the-counter  market are valued at the mean  between  the last bid and asked
prices in such market,  except that securities admitted to trading on the NASDAQ
National  Market  System are valued at the last sales price if it is  determined
that  such  price  more  accurately  reflects  the  value  of  such  securities.
Short-term securities are carried at cost which approximates market.  Securities
for which market  quotations  are not  available  are valued at fair value under
procedures  approved by the Board of Trustees.  (b) Transactions  denominated in
foreign  currencies are recorded in the Company's records at the rate prevailing
when earned or incurred.  Asset and liability  accounts that are  denominated in
foreign currencies are adjusted to reflect current exchange rates. (c) It is the
policy  of the  Trust to meet the  requirements  of the  Internal  Revenue  Code
applicable  to  regulated  investment  companies  and to  distribute  all of its
taxable  income in  taxable  distributions.  Therefore,  no  federal  income tax
provision is required.  (d) Security  transactions are accounted for on the date
that the  securities  are  purchased or sold (trade  date).  Realized  gains and
losses from investment transactions are calculated on the identified cost basis.
Dividend  income  and   distributions   to  shareholders  are  recorded  on  the
ex-dividend  date.  Interest  income  is  recorded  on the  accrual  basis.  Net
investment  income (other than  distribution  and service fees) and realized and
unrealized  gains or losses are allocated to each class of shares based upon the
relative  proportion of net assets at the beginning of the day. (e) A portion of
the proceeds  from sales and cost of  repurchases  of shares,  equivalent to the
amount of distributable net investment income on the date of the transaction, is
credited or charged to undistributed income. Undistributed net investment income
per  share  thus is  unaffected  by  sales or  repurchases  of  shares.  (f) The
organization expenses are amortized evenly over a period of five years.

2. Management Fee and Other Transactions with Affiliates

The Trust has a  management  agreement  with Lord Abbett  pursuant to which Lord
Abbett supplies the Trust with investment  management services and executive and
other personnel,  pays the  remuneration of officers,  provides office space and
pays for  ordinary  and  necessary  office and  clerical  expenses  relating  to
research  and  statistical  work  and  supervision  of  the  Trust's  investment
portfolios.  The management fee is based on average daily net assets at the rate
of .75% per annum.  Lord Abbett may waive its  management  fee and reimburse the
Trust for  certain  of its other  expenses.  Any such  other  expenses  paid are
subject to repayment by the Trust, pursuant to a formula based on the asset size
and expense  ratio of each  Series.  Each Series shall not be obligated to repay
Lord Abbett after five full fiscal years of operation or the  termination of the
management agreement,  whichever is earlier. Lord Abbett has entered into a sub-
advisory   agreement  with  Fuji  Investment   Management  Co.  (Europe),   Ltd.
("sub-adviser").  The  sub-adviser  furnishes  investment  advisory  services in
connection with the management of the International Series. Lord Abbett pays for
the cost of the sub-adviser's  services. 

Each Series of the Trust has Rule 12b-1 plans and agreements with respect to one
or more classes of shares as  described  below (the "Class A and Class C Plans")
with Lord Abbett Distributor LLC ("Distributor"), an affiliate of Lord Abbett.
Each Series makes payments to Distributor  which uses or passes on such payments
to  authorized  institutions.  Pursuant  to the Class A Plan,  each  Series pays
Distributor  (1) an annual  service fee of 0.25% of the average daily net assets
of Class A shares  and (2) a  one-time  distribution  fee of up to 1% on certain
qualifying  purchases and a supplemental annual distribution fee of 0.10% of the
average  daily  net  assets of Class A shares  serviced  by  certain  qualifying
institutions.  Pursuant to the Class C Plan of the Growth & Income  Series,  the
Series pays  Distributor  (1) a service fee and a distribution  fee, at the time
such shares are sold,  not to exceed 0.25% and 0.75%,  respectively,  of the net
asset  value of such  shares  sold and (2) at each  quarter-end  after the first
anniversary of the sale of such shares,  a service fee and a distribution fee at
an annual  rate not to exceed  0.25% and  0.75%,  respectively,  of the  average
annual net asset value of such shares outstanding.

12b-1  distribution plan expenses for the Growth & Income Series' multiple class
shares were as follows:

- --------------------------------------------------------------------------------
Class A                                                  $  51,488
- --------------------------------------------------------------------------------

Lord Abbett  received the following  commissions on sales of shares of the Trust
after concessions were paid to authorized distributors:

- --------------------------------------------------------------------------------


3. Distributions

Dividends  from net  investment  income are declared and paid  quarterly for the
Growth & Income Series and annually for the International  Series.  Net realized
gains from  investment  transactions,  if any, are  distributed to  shareholders
annually.  At April 30, 1997, the  accumulated  undistributed  net realized gain
(loss) for financial reporting purposes,  aggregated $3,866,568 for the Growth &
Income  Series  and  $(100,838)  for  the  International  Series.  Distributions
declared for the Growth & Income Series on May 7, 1997 were as follows:

                                                        Rate           Aggregate
                                                   Per Share              Amount

Income and capital gains  distributions are determined in accordance with income
tax   regulations   which  may  differ  from  methods  used  to  determine   the
corresponding  income and capital  gains amounts in  accordance  with  generally
accepted  accounting  principles.


                                                                               5
