The worldwide  "flight to quality" that drove U. S. Treasury bond yields down in
1998 gave way as global political and economic uncertainties began to resolve in
early  1999.  Sparked  by a series of late 1998 Fed Rate  cuts,  interest  rates
remained  low early in the year but  gradually  crept  higher  amid  reports  of
increased inflation.

Both  the U.  S.  Government  Securities  Series  and  Limited  Duration  U.  S.
Government Securities Series continued to emphasize mortgage-backed  securities,
such as FNMAs, FHLMCs, collateralized mortgage obligations (CMOs) and commercial
mortgage-backed  securities  (CMBs). We believe that these sectors continue++ to
represent good value for investors as the incremental  yield over Treasuries has
remained  high.  As  releases  of new  economic  data  began to  signal a slight
increase in inflation  (and the potential for preemptive  Federal  Reserve Board
action),   we   invested   in   shortand   long-term   Treasuries   rather  than
intermediate-term  Treasuries.  This approach worked,  as intermediates  saw the
largest yield increase during the second quarter of 1999.  During periods of low
relative  prices,  we  will  continue  to  take  the  opportunity  to add to our
weighting of mortgagebacked securities.

The Balanced Series  utilizes a "fund of funds" format which  currently  divides
assets  approximately  55%/45% between Lord Abbett  Affiliated Fund (equity) and
Lord Abbett Bond-Debenture Fund (fixed income),  respectively.+  Affiliated Fund
benefited from the performance of some of its telecommunication,  technology and
financial  services stocks. We increased our exposure to insurance stocks, as we
expect  this sector to benefit  from  consolidations.  The  overall  strategy of
Bond-Debenture  Fund is to identify  good bond values while being  careful about
credit    selection.    With   a   current    allocation    of   over   65%   in
high-yield/lower-rated issues (including convertibles), we reduced our corporate
bond  holdings in basic  industries  such as steel,  paper and  chemicals  as we
believe there is little opportunity for these companies to raise prices on their
products.  We are emphasizing  industries  that have steady cash flows,  such as
telecommunications,  media  and  cable  television  providers.  We  expect  that
longterm returns should be enhanced due to our selection of high-yield debt from
well-managed  companies.  Overall,  we  believe  high-yield  bonds  continue  to
represent  particularly good value due to their significant yield advantage over
Treasuries.++

Lord Abbett High Yield Fund commenced  operations on December 31, 1998. The Fund
invests in  high-yield/lower-rated  bonds with a focus on domestic debt, and has
the ability to invest up to 20% in foreign securities.  The investment objective
of High  Yield  Fund is to seek high  current  income  and the  opportunity  for
capital appreciation to produce a high total return.

Thank you for making  Lord  Abbett  Investment  Trust a part of your  investment
portfolio.  We remain  committed to helping you achieve your financial  goals in
the years ahead.

*Total return, which is not annualized, is the percent change in net asset value
assuming the reinvestment of all distributions.

**The inception date for High Yield Fund Class Y shares was 5/4/99.

+The portfolio is actively managed, and as a result, asset allocation may change
from time to time.

++ Unlike  Treasury  securities,  an investment in the Series is neither insured
nor guaranteed by the U. S. government.

ABOUT THE U. S. GOVERNMENT SECURITIES SERIES

Total Return is Important to Fixed-Income Investors

Over the last 15 years, an investment in the Series provided  relatively  stable
dividend income and,  assuming the  reinvestment of all  distributions,  grew by
over 393%.  The Series  surpassed  the increase in inflation (as measured by the
Consumer Price Index),  and the Lipper General U. S. Government Average over the
same 15-year period.

(2)  Each percentage  amount shown is calculated based on the Fund's holdings of
     Long-Term  Investments only. A security subject to principal  paydowns over
     time (as is the case with most mortgage-related  investments) is classified
     as  long-term if the expected  average  time until  principal  payments are
     received,  weighted  by  dollar  amount,  is  greater  than one  year.  All
     short-term assets,  including cash and cash equivalents,  are excluded from
     the calculation for purposes of this chart.

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

Each Series' respective SEC yield is calculated on its maximum offering price on
6/30/99,  using a  standard  method  which  does not take into  account  certain
portfolio  strategies.   Series'  distribution  rates  differ  from  SEC  yields
primarily because each Series purchases short-and intermediate-term, high-coupon
securities  at a premium and  distributes  to  shareholders  all of the interest
income on those  securities  without  amortizing the premiums.  This practice is
consistent with applicable tax  regulations  and generally  accepted  accounting
principles,  but may result in a decrease  in the net asset  values of shares of
the Series as the market  values of the premium  securities  decrease over time.
Dividends paid from this interest income are taxable to shareholders as ordinary
income.  Neither the U. S. Government Securities Series nor the Limited Duration

charge  schedules  and  reflect  appropriate  Rule  12b-1  Plan  expenses.   Tax

charge structure has changed from the past. If interest rates rise, the value of
bonds purchased by the Series would decrease,  causing a decrease in the Series'
share  values.  If used as sales  material  after  9/30/99,  this report must be

Notes to Financial Statements

1. Significant Accounting Policies

Lord Abbett Investment Trust (the "Trust") is an open-end management  investment
company  organized as a Delaware  business  trust on August 16, 1993.  The Trust
consists of six separate  portfolios.  This report covers four of the portfolios
(" Series") -Lord Abbett U. S. Government  Securities Series (" U. S. Government
Series"),  Lord Abbett Limited  Duration U. S. Government  Securities  Series ("
Limited Duration Series"),  Lord Abbett Balanced Series (" Balanced Series") and
Lord Abbett High Yield Fund (" High Yield Fund").  Effective March 31, 1998, the
Balanced  Series  structure  was changed  from  investing  directly in portfolio
securities  to  investing  in other funds  managed by Lord Abbett ("  Underlying
Funds"). Effective December 1, 1998, the High Yield Fund was added and the Trust
received a capital contribution of $1,000,000 and issued 100,000 shares to 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  require
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) Securities are valued as follows: Portfolio securities listed or admitted to
trading privileges on any securities exchange are valued at the last sales price
on the exchange on which such  securities are traded as of the close of business
on the day the securities are being valued or, lacking any sales,  at the latest
price on the basis of current quotations from dealers (as in the case of bonds),
from  valuations  furnished  by an  independent  pricing  service  or,  in their
absence,  fair value as  determined  under  procedures  approved by the Board of
Trustees.  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
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. Shortterm
securities  maturing  in 60 days or less are  valued  at  amortized  cost  which
approximates market value.

(b) 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.

(c) 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 determined on the identified  cost basis.  Dividend income and
distributions  to shareholders are recorded on the ex-dividend date and 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.  Discounts on strips are accrued to maturity
using the constant yield method.  The Trust has elected not to amortize premiums
on U. S.  Government  bonds,  which is consistent with the treatment for federal
income tax purposes.

(d) The  organization  expenses of Balanced  Series are amortized  evenly over a
period of five years from its respective commencement date of operations.

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,  research, statistical and
advisory services and pays officers'  remuneration and certain other expenses of
the Trust.  The  management  fee is based on  average  daily net assets for each
month at the  annual  rate of 0.50%  for U. S.  Government  Series  and  Limited
Duration  Series,  0.75% for Balanced  Series and 0.60% for High Yield Fund. The
management fee for U. S. Government Series is reduced to 0.45% for average daily
net assets in excess of $3 billion.  Lord Abbett waived its  management  fee for
Limited  Duration  Series,  Balanced  Series and High Yield Fund  during the six
months ended May 31, 1999.

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 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,  the Series
pay  Distributor (1) an annual service fee of (a) 0.15% of the average daily net
asset value of shares sold prior to  September  1, 1985 and 0.25% of the average
daily net asset value of shares sold on or after that date for U. S.  Government
Series and (b) 0.25% of the  average  daily net asset value of Class A shares of
Limited  Duration  Series,  Balanced  Series and High Yield Fund, (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 of Class A
shares.  The Class A Plan of Limited  Duration Series will not become  operative
until the first day of the calendar quarter subsequent to the Series' net assets
reaching $100 million.  Pursuant to the Class B Plan of U. S. Government Series,
Balanced  Series and High  Yield  Fund and the Class C Plan of High Yield  Fund,
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  shares
outstanding  for the class.  Pursuant  to the Class C Plan of U. S.  Government,
Limited Duration and Balanced Series, 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. Class Y does not have a Rule 12b-1 Plan.

The  Balanced  Series  has  entered  into  a  Servicing  Arrangement  with  each
Underlying Fund pursuant to which each Underlying Fund will pay a portion of the
expenses  (excluding  management  fee,  distribution  and  service  fees) of the
Balanced  Series in proportion to the average daily value of shares owned by the
Balanced Series to the extent each Underlying Fund benefits.

Distributor  received the following  commissions on sales of shares of the Trust
after concessions were paid to authorized dealers:

annually.  At May 31, 1999,  accumulated  net realized gain (loss) for financial
reporting purposes aggregated $(573,403,249), $(1,691,159), $(7,710) and $79,880
