About Growth & Income Series

Market Review

Evidence  of a possible  global  economic  recovery  emerged  early in 1999.  By
mid-year,  it became  apparent that global  economic  conditions  were generally
improving,  as reflected in  increasing  demand for  commodities  such as paper,
metals and  chemicals.  Much of the global rebound was attributed to the Federal
Reserve  Board's move in the autumn of 1998 to lower U.S.  interest  rates in an
effort to pump liquidity into many of the world's faltering economies. As global
markets continued to improve  throughout 1999, the Federal Reserve Board decided
that this  stimulus  was no longer  needed,  resulting  in a series of fall rate
hikes that have normalized U.S. interest rates from their record lows last year.
Overall,  GDP growth in the U.S. remained strong  throughout the period,  with a
healthy labor market generating steady production and income gains.

*    Total  return  is the  percent  change  in  value  with all  dividends  and
     distributions  reinvested  for the periods  shown,  using the  SEC-required
     uniform method to compute such returns.

Report to Shareholders

Portfolio Review

Rising  interest  rates  in  recent  months  caused  a  leadership  shift in the
large-cap  market as  interest-rate-sensitive  sectors,  such as  utilities  and
financial  services,   underperformed,   while  technology  stocks  demonstrated
tremendous  relative strength despite their high valuations.  Over the course of
the  year,  the  Series  remained  underweighted  in the  financial  sector,  in
anticipation of rising  interest rates.  Likewise,  we were  well-positioned  to
benefit  from the  leadership  position of the  technology  sector,  with select
holdings  generating  strong  gains.  We also  increased  our  exposure in basic
materials  industries,  in  anticipation  of further  global  economic  recovery
throughout 2000 and 2001.


Outlook

We expect to see global economic growth continue  throughout the coming year. In
response,  we are adding  holdings in sectors  which this  recovery is likely to
favor such as basic  materials and capital  goods.  In the U.S.,  some signs are
emerging that the economy may be  moderating.  With a diminished  risk of future
U.S. interest rate hikes, we are reconsidering  financial services stocks,  many
of which display solid fundamentals at attractive prices, a strategic adjustment
that  could be  especially  timely  as  technology  stocks  become  increasingly
expensive.

RISK: Lord Abbett Securities Trust - Growth & Income Series may invest up to 10%
of net assets in  foreign  securities.  Foreign  securities  markets  may not be
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.  Foreign  investments may
also be subject to currency exposure.



About International Series

Market Review

During the last months of 1998, many of the world's  financial  markets began to
signal a possible recovery from a two-year period of financial crisis and global
deflation.  By mid 1999,  it became  apparent  that this  recovery was real,  as
economic indicators pointed to a new phase of global economic expansion.

In the international  equity markets,  Europe, which remained subdued throughout
much of the period,  picked up recently,  as recession  fears proved  false.  In
addition, many European companies posted better-than-expected earnings growth in
recent  weeks due to a solid  local  economy  and a weak euro,  relative  to the
dollar and the yen, which boosted exports.  Japan, which benefited from a series
of  economic  initiatives  during  the  period,   continued  to  show  signs  of
improvement,  as it  attracted  overseas  money on the  strength of its apparent
recovery and its relative importance to international investors.


Portfolio Review

The Series  continued  to  implement  its  investment  strategy  of  focusing on
attractively   priced,   industry-dominant   companies  with  global  leadership
potential.  During the period, the Series remained  overweighted in European and
Canadian companies that demonstrated  superior corporate earnings,  growth rates
and  valuation  levels  relative to many  companies in the Far East and emerging
markets.   In  general,  we  limited  our  exposure  to  Japanese  companies  in
traditional, old-style industries such as steel, chemicals and paper, because we
believe  they  require  further  corporate   restructuring.   In  addition,  the
sluggishness of Japan's overall economy does not bode well for those industries.
However,  the Series has invested in select Japanese  companies within new-style
industries,  such as telecommunications and software. Indeed, a handful of these
high-tech issues have accounted for the majority of recent gains in the Japanese
markets.

                                                                               1

<PAGE>


Outlook

During the next year,  we expect  European  economic  growth to average over 2%.
This modest  growth  rate,  coupled  with  significant  corporate  restructuring
programs,  will create an attractive  combination of relative value and earnings
growth  potential.  In the Far East,  we see an even greater  dichotomy  between
"Old-Japan-style"   traditional   industry   and   "New-Japan-style"   high-tech
businesses.  We expect  "New-Japan-style"  shares to continue to  appreciate  as
investors focus their capital in these rapidly growing sectors.

RISK: Lord Abbett  Securities Trust - International  Series will invest at least
80% of net assets in foreign  securities  under normal  market  conditions.  The
Series primarily invests in small-cap securities,  which may be more volatile in
price,  normally have fewer shares  outstanding  and trade less  frequently than
large  companies.  Foreign  securities  markets  may not be  subject to the same
degree of regulations as and may be more volatile and less liquid than the major
U.S. markets.
The Series' portfolio is actively managed and is subject to change.



About World Bond-Debenture Series


Market Commentary

Stronger global economic growth and a rebound in commodities prices were central
themes  throughout the period.  As expected,  the U.S. Federal Reserve Board, as
well as several key  European  Central  Banks,  responded to this growth and the
ensuing  concerns  about  inflation  with  interest rate hikes over the past few
months.  Much of this  anticipated rate  tightening,  however,  had already been
discounted  earlier in the year in the prices of both emerging market and global
high-yield issues,  setting the stage for better performance moving forward.  In
general,  global growth has benefited many emerging market  countries which tend
to be commodity producers.


Portfolio Review

Lord Abbett Securities Trust - World Bond-Debenture Series performed well during
the period compared to the Lipper Global Income Funds Index. Much of the Series'
global   high-yield   investment   gains  were   generated   in  the  cable  and
telecommunications sectors where the consolidation of several European companies
increased demand for these issues. In the convertible  sector,  the Series added
value for shareholders by increasing  exposure to  investment-grade  convertible
issues,  both in the U.S.  and in Europe.  In the emerging  markets,  the Series
benefited from its positions in South Korean  sovereign debt, which was recently
upgraded   to   investment   grade,   as  well  as  from   positions   in  other
higher-yielding,  emerging market credits such as Malaysia, Mexico and Bulgaria.
Even the  recent  rate hikes by three  major  central  banks - the U.S.  Federal
Reserve,  the  European  Central  Bank and the Bank of England - have  failed to
blunt the  appetite for  emerging  markets  debt.  Another  rate  increase  may,
however, call into question any further spread tightening.


Outlook

We anticipate that global growth should continue to improve, benefiting emerging
markets in the new year.  Provided that the U.S.  Federal Reserve Board succeeds
in  engineering  a soft  landing  for the  U.S.  economy,  we  expect  that  the
convertible and high-yield markets should remain attractive. Preemptive interest
rate hikes by the  European  Central Bank as well as by the Bank of England have
had little impact on the burgeoning European  high-yield market,  which has been
driven by the push to restructure the energy and  telecommunication  industries.
Overall,  we expect that  investor  sentiment  toward both  emerging  market and
corporate  high-yield  bonds will remain  positive as investors  throughout  the
world continue to seek higher yielding  assets.  With its strategic  focus,  the
Series  seems  well-positioned  to  continue to benefit  from the global  growth
surge.

RISK: Lord Abbett Securities Trust - World Bond-Debenture Series has the ability
to invest  substantially  in  high-yield  securities.  The  risks of  high-yield
securities include, but are not limited to, price volatility and the possibility
of default in the timely  payment of interest and  principal.  In addition,  the
Series has the ability to invest  substantially in foreign  securities.  Foreign
securities  markets may not be 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. Foreign investments are subject to currency exposure.

The Series' portfolio is actively managed and is subject to change.

About Alpha Series

Market Review

o    U.S. Small-Cap Market. Despite a brief rally during the second quarter, the
     small-cap market in the U.S. has lagged the robust performance of the broad
     market. Much of this  underperformance can be attributed to the recent rise
     in interest rates which particularly  affected  lower-liquidity,  small-cap
     issues.  Within the small-cap  arena,  the small-cap growth sector has been
     positively influenced by the continuing  outperformance of Internet-related
     stocks, while the less-liquid small-cap value sector has continued to lag.

o    International  Equity Markets.  Investors have recently  exhibited  renewed
     confidence  in European  markets as  recessionary  fears  proved  false and
     corporate earnings rebounded from subdued levels. As concerns about renewed
     inflation and the stability of emerging markets eased, investors around the
     world became more  confident that the promise of global  economic  recovery
     had become a reality. During the period, many of the world's stock markets,
     particularly  the U.S., Japan and the Far Eastern  emerging  markets,  rose
     significantly.  Japanese markets benefited from improved investor sentiment
     as its economy continued to show signs of recovery.


Portfolio Review

o    Lord Abbett  Developing  Growth Fund  (Approximately  30% of Alpha  Series'
     portfolio).  Technology stocks drove the small-cap growth sector during the
     past year, and the Fund was well-positioned to benefit from these advances.
     Select holdings in the energy and retail sectors also performed well.

o    Lord Abbett Research Fund - Small-Cap  Series  (Approximately  30% of Alpha
     Series'   portfolio).   As  uncertainty   regarding  U.S.   interest  rates
     intensified,  the Series  reduced its positions in  economically  sensitive
     industries such as banking,  housing and autos, in favor of sectors such as
     technology and consumer goods. Select holdings in the energy sector,  which
     benefited from rebounding global commodities  prices,  also added value for
     shareholders.

o    Lord Abbett Securities Trust - International  Series  (Approximately 40% of
     Alpha Series' portfolio).  The Series continued to focus on "Best of Breed"
     companies: those that show exceptional global leadership potential in their
     respective  industries.  We  maintained  an  overweighting  in European and
     Canadian  companies which exhibited  promising  growth rates and attractive
     valuation  levels  and  strong  gains  were  generated  in most of our U.K.
     holdings. Select investments were also made in "New-Japan-style" companies,
     including technology,  software and Internet ventures, which have accounted
     for the majority of Japanese market gains in recent months.


Outlook

o    U.S. Small-Cap Market. With the recent series of Federal Reserve Board rate
     increases  now  behind us, we expect the  small-cap  sector to show  better
     relative  performance moving forward. We believe that a stable U.S. economy
     along with an  improving  global  economy  will also  assist the  small-cap
     market.  Small  caps,  compared  to their  large-cap  counterparts,  remain
     meaningfully  undervalued.  Therefore,  we believe this represents a unique
     opportunity to invest in select small companies.

o    International  Equity Markets.  We believe that a moderate  European growth
     rate of approximately 2%, along with subsiding  concerns about economic and
     corporate  earnings  growth,  will help  European  markets to perform  well
     moving  into next year.  Although  we expect  certain  high-tech  issues to
     continue to buoy the  Japanese  market,  we believe  that  Japan's  overall
     economy is still in recession with few short-term growth prospects. We will
     continue to watch the economic  developments  in Japan, as we believe their
     full economic recovery hinges largely on government spending.

RISK:  The underlying  Funds in this Series are primarily  invested in small-cap
securities  (including  U.S. and global),  which may be more  volatile in price,
normally have fewer shares  outstanding and trade less frequently than large-cap
companies.  In  addition,  the  underlying  Funds have the  ability to invest in
foreign securities,  high-yield  securities and derivatives.  Foreign securities
markets may not be 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.  Foreign
investments are subject to currency exposure. The risks of high-yield securities
include, but are not limited to, price volatility and the possibility of default
in the timely  payment of  interest  and  principal.

The Series' portfolio is actively managed and is subject to change.

                                                                               3

When We Shop for Stocks, We Shop for Bargains

When it comes to stock selection,  the portfolio  manager of the Growth & Income
Series  tries to be a savvy  buyer.  We have an  experienced  team of  financial
professionals  whose approach  includes elements similar to those taken by smart
shoppers.

When you think about how you shop, you realize that you like to find bargains.

Savvy  shoppers  often  check out the sales racks to find items with a low price
tag. Of course,  just  because "the price is right" does not mean that a product
is worth buying.  A smart shopper will carefully  inspect the item,  checking it
for defects and overall  quality.  Another  important test required by the smart
shopper:  usability and function.  If the item is not in style,  or is something
that would not likely be used, there is probably no point in buying it.

Quantitative Research:

Performed on a universe of the 1,000 largest U.S. and multinational companies to
identify those stocks that we believe represent the best bargains:  a "low price
tag."

Fundamental Research:

Conducted to assess a company's operating  environment,  resources and strategic
plans,  and to determine its  prospects for exceeding the earnings  expectations
reflected in its stock price: "overall quality."

Business Cycle Analysis:

Used to  assess  the  economic  and  interest-rate  sensitivity  of the  Series'
portfolio.  This  analysis  helps the  portfolio  manager  assess  how adding or
eliminating  stocks  changes  a  portfolio's  overall  sensitivity  to  economic
activity and interest rates: "Is it in style?"

The Flexibility You Need to Pursue
Outstanding Bond Performance Worldwide

Ask More from Your Fixed-Income Investments

Would you like to earn more current income while  reducing  overall risk in your
portfolio?  Diversifying  your current bond portfolio  outside the United States
may potentially be an effective way to pursue both objectives.

Lord Abbett  Securities Trust - World  Bond-Debenture  Series seeks high current
income and  capital  appreciation  by  participating  in foreign  debt  markets.
Investing in these markets may provide  substantial yield advantages as compared
with investing in U.S. bonds. The decision to diversify into non-U.S.  bonds may
also make  sense  from a  risk-diversification  standpoint  since the  economies
underlying  foreign  markets  are not  necessarily  synchronized  with  the U.S.
economy.


4-Way Portfolio Focus

The centerpiece of World Bond-Debenture  Series is a strategic  flexibility that
enables it to "go where the yield is" and  pursue  outstanding  bond  investment
opportunities worldwide.

As a  preliminary  step,  the  Series'  experienced  portfolio  management  team
conducts  extensive  research into  economic,  political  and market  factors to
uncover  value among  economic  regions  and  individual  countries.  The team's
regional  and  country  decisions  are then  supplemented  by  asset  allocation
strategies for:

o    High-Yield  Corporate Debt: The Series'  lower-rated debt holdings pay high
     income and help to  minimize  the  effects of  interest-rate  fluctuations.
     Price  appreciation  may  result if the  credit  rating of debt  issuers is
     upgraded.

o    High-Grade Debt:  High-quality  corporate issues, U.S. Government and other
     sovereign-backed securities provide a dependable stream of current income.

o    Equity-Related  Securities:  Capital appreciation is sought by investing in
     convertible bonds that may be exchanged for common stock. When the stock of
     the  underlying  company  rises,  these  equity-related   issues  generally
     increase in value.

o    Emerging Market Debt:  Emerging-market  debt securities  provide attractive
     high-income  opportunities.  Price  appreciation  may  result  from  rating
     upgrades of country debt.

Three Great Small-Cap Funds

Make One Great Core Investment

Don't Chase Past Small-Cap Performance

Investing in small  companies  that are industry  leaders or offer  breakthrough
products  can be very  rewarding.  U.S.  growth,  U.S.  value and  international
small-cap markets,  however, seldom move in the same direction at the same time.
This means  investors who chase  small-cap  returns by investing in sectors with
the best recent results are often disappointed when the sector they choose fails
to produce the highest immediate returns.

Choose Lord Abbett's Unique "Fund of Funds" Approach

We believe Lord Abbett Securities Trust - Alpha Series is a smart way to tap the
potential  of the  small-cap  arena  and  merits  your  consideration  as a core
investment.  The  Series'  "fund of  funds"  approach  accesses  three  distinct
portfolios and management teams.

o    For U.S.  Small-Cap Growth  Exposure:  Lord Abbett  Developing  Growth Fund
     invests  in stocks of small  growing  companies,  many of which are  highly
     specialized  and  in  niche  markets  (approximately  30% of  Alpha  Series
     portfolio).

o    For U.S.  Small-Cap Value  Exposure:  Lord Abbett Research Fund - Small-Cap
     Value Series invests in stocks of established  undervalued  small companies
     (approximately 30% of Alpha Series portfolio).

o    For  International  Small-Cap  Exposure:  Lord  Abbett  Securities  Trust -
     International  Series  invests  mainly  in  stocks  of small  international
     companies (approximately 40% of Alpha Series portfolio).

Please note that the Alpha  Series  portfolio  is actively  managed and that its
percentage allocations may change from time to time.

For Equity Unique "Fund of Funds" Benefits

o    Provides   potentially  higher  returns  by  diversifying   globally  among
     small-cap markets.

o    Potentially dampens portfolio risk by spreading  investment decisions among
     three distinct management teams.

o    Eliminates the need to expensively reallocate your small-cap assets.

A Note About Year 2000 Matters

As you may know, there has been extensive media coverage about possible problems
that may arise as a result of  uncertainties  about the ability of  computers to
"understand"  dates  using the year  2000.  Potentially,  these  problems  could
disrupt  the  services  and  systems  that  the  Fund  relies  on in  its  daily
operations.

As a general  matter,  we believe the financial  industry has taken a leadership
role  addressing  year  2000  (Y2K)  issues  and  this  should  help to  inspire
confidence  among concerned  investors.  More  specifically,  Lord Abbett,  Lord
Abbett  Distributor  LLC and the  Fund's  transfer  agent,  custodian  and other
providers  of  services  critical  to the Fund have  been  actively  working  on
reviewing and replacing or updating  computer  systems and  computer-to-computer
interfaces, as needed. Each has completed or is in the process of testing new or
revised systems and interfaces and generally expects that their systems, as well
as those of their key external  service  providers,  will be ready to handle Y2K
without significant  problems.  Furthermore,  the Fund has been routinely taking
each  company's  Y2K  preparations  into account when  considering  or reviewing
investments.

In summary,  while the Y2K  problem is  unprecedented  and we cannot  completely
eliminate  the  possibility  that the Fund could be affected in some way, we are
confident that all parties involved are taking  appropriate steps to resolve Y2K
concerns.

Important Information

Results  quoted  herein  reflect  appropriate  Rule  12b-1  Plan  expenses  from
commencement of the Plan. Tax consequences  are not reflected.  If used as sales
material  after  12/31/99,  this report  must be  accompanied  by Lord  Abbett's
Performance Quarterly for the most recently completed calendar quarter.

Foreign  investment  risk factors  include the potential for less regulation and
liquidity  and  more  volatility  than  U.S.  markets;   currency   fluctuation;
potentially  less  publicly-available  information  about  companies,  banks and
governments than for U.S.  counterparts;  lack of uniform  accounting  standards
among countries, impairing comparisons; potentially higher transaction costs and
different securities settlement practices.

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. The Trust currently consists of
seven  separate  portfolios  ("Series")-This  report covers the  following  four
Series:  Lord Abbett Growth & Income  Series  ("Growth & Income  Series"),  Lord
Abbett  International  Series  ("International   Series"),   Lord  Abbett  World
Bond-Debenture  Series  ("World  Bond-Debenture  Series")  and Lord Abbett Alpha
Series ("Alpha  Series").  The Alpha Series invests in other funds  ("Underlying
Funds") managed by 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)
Security  valuation is determined  as follows:  Portfolio  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 ask  prices on such  exchange.  Securities  traded  in the  over-the-counter
market  are  valued  at the mean  between  the last bid and ask  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.  Investments  in the
Underlying  Funds are valued at the  closing  net asset  value per share of each
Underlying Fund on the day of valuation.  Short-term  securities  maturing in 60
days or less are valued at  amortized  cost  which  approximates  market  value.
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 Trust'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) The  International  and World  Bond-Debenture  Series may use forward
currency contracts to hedge the risk to the portfolios of unfavorable  movements
in  foreign  exchange  rates.  (d) 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.  Therefore,  no federal
income tax provision is required.  (e) Security transactions are recorded 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. (f) 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 0.75% per annum for International and World  Bond-Debenture  Series and 0.50%
per annum for the Alpha Series. The management fee for Growth & Income Series is
based on average  daily net assets at the following  annual rates:  0.75% on the
first $200 million; 0.65% on the next $300 million; and 0.50% on the excess over
$500 million.  Lord Abbett waived its fee for the World Bond-Debenture and Alpha
Series for the year ended October 31, 1999. At October 31, 1999, management fees
payable were $118,043  forGrowth & Income Series and $139,980 for  International
Series.  Lord Abbett has entered into a  sub-advisory  agreement  with Fuji-Lord
Abbett International,  Ltd. ("sub-adviser").  Lord Abbett is a minority owner of
the  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, Class B, Class C,
and Class P  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 asset value of Class A shares, (2) a one-time distribution fee
of up to 1% on certain qualifying  purchases and (3) an annual  distribution fee
of 0.10% of the average daily net asset value ofClass A shares.  Pursuant to the
Class B Plan,  each Series pays  Distributor an annual service and  distribution
fee of 0.25% and 0.75%,  respectively,  of the average  daily net asset value of
the Class B shares.  Pursuant to the Class C Plan, each 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.  Pursuant to the Class P Plan of International  Series, the
Series pays  Distributor  an annual  service and  distribution  fee of 0.20% and
0.25%, respectively, of the average daily net asset value of the Class P shares.
Class Y does not have a Rule 12b-1  plan.  At October 31,  1999,  the 12b-1 fees
payable were $534,054 for Growth & Income Series,  $279,  869 for  International
Series, $23,887 for World Bond-Debenture Series and $497,499 for Alpha Series.

TheAlpha  Series has entered into a Servicing  Arrangement  with the  Underlying
Funds pursuant to which each  Underlying Fund will pay a portion of the expenses
(excluding management fee, distribution and service fees) of the Alpha Series in
proportion to the average daily value of shares owned by the Alpha Series. Other
expenses  for  International  Series,  one  of  the  Underlying  Funds,  include
approximately $215,000 accrued pursuant to this Servicing Arrangement.

Distributor  received the following  commissions  for the year ended October 31,
1999 on sales of shares of the Trust after  concessions  were paid to authorized

Trustees'  fees and retirement  costs are allocated  among all funds in the Lord
Abbett group based on net assets of each fund. Trustees' fees payable at October
31, 1999, under a deferred compensation plan were $153,496.

7. Expense Reduction
The Trust has  entered  into an  arrangement  with its  transfer  agent  whereby
credits  realized as a result of uninvested  cash balances were used to reduce a
portion of the Trust's expenses.

8. Line of Credit
The Growth & Income and  International  Series,  respectively with certain other
funds managed by Lord Abbett, have available a $200,000,000  unsecured revolving
credit  facility  ("Facility"),  from a  consortium  of  banks,  to be used  for
temporary or  emergency  purposes as an  additional  source of liquidity to fund
redemptions of investor  shares.  Any  borrowings  under this Facility will bear
interest at current market rates as defined in the  agreement.  The fee for this
Facility was at an annual rate of 0.06% during the year.  Effective December 17,
1999, this fee was increased to 0.09% per annum. There were no loans outstanding
pursuant to this Facility at October 31, 1999, nor was the Facility  utilized at
any time during the year.


Independent Auditors' Report
The Board of Trustees and Shareholders,
Lord Abbett Securities Trust:

We have  audited  the  accompanying  statements  of net  assets  of Lord  Abbett
Securities   Trust-Growth  &  Income   Series,   International   Series,   World
Bond-Debenture  Series and Alpha  Series as of October  31,  1999,  the  related
statements  of  operations  and of  changes  in net  assets  and  the  financial
highlights for each of the periods presented. These financial statements and the
financial  highlights are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these  financial  statements and the
financial highlights based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures included confirmation of securities owned at October
31, 1999 by  correspondence  with the custodian and brokers;  where replies were
not received from brokers, we performed other auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.
I
n our opinion,  such  financial  statements  and financial  highlights  present
fairly,  in all  material  respects,  the  financial  position  of  Lord  Abbett
Securities   Trust-Growth  &  Income   Series,   International   Series,   World
Bond-Debenture Series and Alpha Series at October 31, 1999, the results of their
operations,  the changes in their net assets and their financial  highlights for
the  respective  periods  presented,   in  conformity  with  generally  accepted
accounting principles.
