LORD ABBETT LARGE-CAP GROWTH FUND
SEMI-ANNUAL REPORT
FOR THE SIX-MONTH PERIOD ENDED JANUARY 31, 2005

DEAR SHAREHOLDERS: We are pleased to provide you with this overview of the Lord
Abbett Large-Cap Growth Fund's (the Fund) strategies and performance for the
six-month period ended January 31, 2005. On this and the following pages, we
discuss the major factors that influenced performance.

    Thank you for investing in Lord Abbett Mutual Funds. We value the trust that
you place in us and look forward to serving your investment needs in the years
to come.

BEST REGARDS,

/s/ Robert S. Dow

ROBERT S. DOW
CHAIRMAN

Q:  WHAT WERE THE OVERALL MARKET CONDITIONS OF THE REPORTING PERIOD?

A:  The U.S. economy showed mixed signs during the six-month period from
July 31, 2004 through January 31, 2005. After slowing during a summer "soft
patch," the economy regained some traction in the third quarter of 2004. Despite
indicators of renewed economic strength, however, stocks finished the third
quarter down slightly. One of the key drivers of stocks during most of the
summer seemed to be the direction of oil prices, with stocks falling as oil
prices rose. This negative correlation lasted until mid-August when crude oil
broke through the $45 per barrel price level. From mid-August through
mid-September, stocks benefited from declining gasoline prices at the pump, a
favorable turn of events for consumers. Equities gathered momentum until a
string of hurricanes on the Gulf Coast forced production disruptions at one of
the nation's largest oil-refining facilities, causing oil prices to rise again
as the quarter ended.

    The combination of declining gasoline prices during much of the third
quarter and the addition of 300,000-400,000 jobs, while lower than expected,
contributed to a pick up in consumer spending in the third-quarter.
Third-quarter unemployment declined to 5.4%. On August 10, 2004, the Federal
Reserve Board (the Fed) raised the fed funds rate from 1.25% to 1.50%. (The fed
funds rate is the rate charged by the Fed to banks needing overnight loans to
meet reserve requirements.) This was followed by another increase to 1.75% on
September 21. Two additional increases in November and December brought the fed
funds rate to 2.25% by year-end.

    In the final quarter of the year, employment increased. The Consumer Price
Index (CPI) increased 0.5% in October and 0.1% in November followed by a
decrease of 0.4% in December. The CPI is a commonly used measure of inflation,
which reflects changes in the prices paid by urban consumers for a
representative basket of goods and services. In addition, the S&P 500 Index(1)
gained 1.5% in October,

                                                                               1
<Page>

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

4.0% in November and 3.4% in December. For 2004 as a whole, the S&P 500 Index(1)
reported a gain of 10.9%.

    In January 2005, the Consumer Confidence Index rose 0.7%. Based on a
representative sample of 5,000 households, the Index measures consumer
confidence about current business, employment and economic conditions as well as
their expectations for the same six months hence. Employment increased by
146,000 in January and the unemployment rate decreased to 5.2%, while the S&P
500 Index(1) declined 2.4%.

Q:  HOW DID THE FUND PERFORM OVER THE SIX-MONTH PERIOD ENDED JANUARY 31, 2005?

A:  For the six-month period ended January 31, 2005, the Fund returned 4.8%,
reflecting performance at the Net Asset Value (NAV) of Class A shares with all
distributions reinvested, compared with its benchmark, the Russell 1000(R)
Growth Index,(2) which returned 6.0% over the same period. Standardized Average
Annual Total Returns, which reflect performance at the maximum 5.75% sales
charge applicable to Class A share investments and include the reinvestment of
all distributions are 1 Year: -7.81%, 5 Year: -15.02%, and Since Inception
(12/30/99): -15.50%. Class A shares purchased subject to a front-end sales
charge have no contingent deferred sales charge (CDSC). However, certain
purchases of Class A shares made without a front-end sales charge may be subject
to a CDSC of 1.0% if the shares are redeemed within 12 months of the purchase.

    PERFORMANCE DATA QUOTED REFLECT PAST PERFORMANCE AND ARE NO GUARANTEE OF
FUTURE RESULTS. CURRENT PERFORMANCE MAY BE HIGHER OR LOWER THAN THE PERFORMANCE
QUOTED. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN INVESTMENT IN THE FUND
WILL FLUCTUATE SO THAT SHARES, ON ANY GIVEN DAY OR WHEN REDEEMED, MAY BE WORTH
MORE OR LESS THAN THEIR ORIGINAL COST. YOU CAN OBTAIN PERFORMANCE DATA CURRENT

Q:  WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE?

A:  The largest detractor to Fund performance for the six-month period ended
January 31, 2005 was stock selection within the technology sector. Overall,
investor concern about a possible peak in the semi-conductor cycle put pressure
on the technology sector. In the Fund's portfolio, a build up of product
inventory in two semi-conductor companies hurt performance. In addition, stock
selection within the consumer discretionary sector also detracted from
performance. The consumer discretionary sector includes companies that produce
or sell goods typically consumed on an irregular or one-time basis. These
include automobiles and components, consumer durables, apparel, hotels,
restaurants, leisure, media and retailing. Stock selection within the producer
durables sector also hurt performance. Producer durables include industrials and
capital goods used in the

2
<Page>

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

production of other goods such as industrial buildings, machinery and equipment.
Consumer concerns about rising interest rates dampened the performance of the
Fund's homebuilder holdings.

    An overweight position and strong stock selection within the financial
services sector were the greatest positive contributors to performance for the
six-month period ended January 31, 2005. Brokerage firm holdings performed well
as investors reacted positively to a generally improving equity market and
economy. Another bank holding also helped performance as their earlier
acquisitions contributed to performance. Furthermore, the Fund benefited from
the portfolio's overweight position and good stock selection within the sector
called "other," which consists of companies that are diversified conglomerates.
The largest holding within this sector was a strong performer as management made
good on past objectives including meeting its earnings numbers.

    THE FUND'S PORTFOLIO IS ACTIVELY MANAGED AND, THEREFORE, ITS HOLDINGS AND
WEIGHTINGS OF A PARTICULAR ISSUER OR PARTICULAR SECTOR AS A PERCENTAGE OF
PORTFOLIO ASSETS ARE SUBJECT TO CHANGE. SECTORS MAY INCLUDE MANY INDUSTRIES.

EXPENSE EXAMPLE

    As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges on purchase payments (these charges vary among
the share classes); and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees (these charges vary among the share
classes); and other Fund expenses. This Example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

    The Example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period (August 1, 2004 through January 31,
2005).

ACTUAL EXPENSES

    For each class of the Fund, the first line of the table on the following
page provides information about actual account values and actual expenses. You
may use the information in this line, together with the amount you invested, to
estimate the expenses that you paid over the period. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number in the first line under the heading
entitled "Expenses Paid During the Period 8/1/04 - 1/31/05" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

    For each class of the Fund, the second line of the table on the following
page provides information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio and an assumed rate of return
of 5% per year before expenses, which is not the Fund's actual return. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

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

    Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.   ORGANIZATION

Lord Abbett Large-Cap Growth Fund (the "Fund") is registered under the
Investment Company Act of 1940 (the "Act") as a diversified, open-end management
investment company. The Fund was organized as a Delaware Business Trust on
September 29, 1999. The Fund commenced operations on December 15, 1999, and the
Securities and Exchange Commission declared the Fund effective and each class of
shares became available to the public on December 30, 1999.

The Fund's investment objective is to seek long-term capital growth. The Fund
offers five classes of shares: Classes A, B, C, P and Y, each with different
expenses and dividends. A front-end sales charge is normally added to the Net
Asset Value ("NAV") for Class A shares. There is no front-end sales charge in
the case of the Classes B, C, P and Y shares, although there may be a contingent
deferred sales charge ("CDSC") as follows: certain redemptions of Class A shares
made within 24 months (12 months if shares were purchased on or after November
1, 2004) following certain purchases made without a sales charge; Class B shares
redeemed before the sixth anniversary of purchase; and Class C shares redeemed
before the first anniversary of purchase. Class B shares will convert to Class A
shares on the eighth anniversary of the original purchase of Class B shares.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
certain estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of increases and decreases in
net assets from operations during the reporting period. Actual results could
differ from those estimates.

2.   SIGNIFICANT ACCOUNTING POLICIES

(a)  INVESTMENT VALUATION-Securities traded on any recognized U.S. or non-U.S.
     exchange or on NASDAQ, Inc. are valued at the last sale price or official
     closing price on the exchange or system on which they are principally
     traded. Unlisted equity securities are valued at the last quoted sale price
     or, if no sale price is available, at the mean between the most recently
     quoted bid and asked prices. Securities for which market quotations are not
     readily available are valued at fair value as determined by management and
     approved in good faith by the Board of Trustees. Short-term securities with
     60 days or less remaining to maturity are valued using the amortized cost
     method, which approximates current market value.

(b)  SECURITY TRANSACTIONS-Security transactions are recorded as of the date
     that the securities are purchased or sold (trade date). Realized gains and
     losses on sales of portfolio securities are calculated using the
     identified-cost method. Realized and unrealized gains (losses) are
     allocated to each class of shares based upon the relative proportion of net
     assets at the beginning of the day.

(c)  INVESTMENT INCOME-Dividend income is recorded on the ex-dividend date.
     Interest income is recorded on the accrual basis. Discounts are accreted
     and premiums are amortized using the effective interest method. Investment
     income is allocated to each class of shares based upon the relative
     proportion of net assets at the beginning of the day.

(d)  FEDERAL TAXES-It is the policy of the Fund to meet the requirements of
     Subchapter M of the Internal Revenue Code applicable to regulated
     investment companies and to distribute substantially all taxable income and
     capital gains to its shareholders. Therefore, no Federal income tax
     provision is required.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)

(e)  EXPENSES-Expenses, excluding class specific expenses, are allocated to each
     class of shares based upon the relative proportion of net assets at the
     beginning of the day. Classes A, B, C and P shares bear all expenses and
     fees relating to their respective 12b-1 Distribution Plans.

(f)  SECURITIES LENDING-The Fund may lend its securities to member banks of the
     Federal Reserve System and to registered broker/dealers approved by the
     Fund. The loans are collateralized at all times by cash and/or U.S.
     Government securities in an amount at least equal to 102% of the market
     value of the securities loaned (105% in the case of foreign securities
     loaned) as determined at the close of business on the preceding business
     day. The dividend and interest income earned on the securities loaned is
     accounted for in the same manner as other dividend and interest income.
     Lending portfolio securities could result in a loss or delay in recovering
     the Fund's securities if the borrower defaults.

(g)  REPURCHASE AGREEMENTS-The Fund may enter into repurchase agreements with
     respect to securities. A repurchase agreement is a transaction in which the
     Fund 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 Fund requires at all times that the repurchase
     agreement be collateralized by cash, or by securities of the U.S.
     Government, its agencies, its instrumentalities, or U.S. Government
     sponsored enterprises having a value equal to, or in excess of, the value
     of the repurchase agreement (including accrued interest). 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, the
     Fund may incur a loss upon disposition of the securities.

3.   MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEE
The Fund has a management agreement with Lord, Abbett & Co. LLC ("Lord Abbett")
pursuant to which Lord Abbett supplies the Fund 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 Fund's
investment portfolio. The management fee is based on average daily net assets at
an annual rate of .75%.

Lord Abbett provides certain administrative services to the Fund pursuant to an
Administrative Services Agreement at an annual rate of .04% of the Fund's
average daily net assets.

12b-1 DISTRIBUTION PLANS
The Fund has adopted a distribution plan with respect to one or more classes of
shares pursuant to Rule 12b-1 of the Act, which provides for the payment of
ongoing distribution and service fees to Lord Abbett Distributor LLC
("Distributor"), an affiliate of Lord Abbett. The fees are accrued daily at
annual rates based upon average daily net assets as follows:

<Table>

Class Y does not have a distribution plan.

One Trustee and certain of the Fund's officers have an interest in Lord Abbett.

4.   DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARD

Dividends from net investment income, if any, are declared and paid at least
annually. Taxable net realized gains from investment transactions, reduced by
capital loss carryforwards, if any, are declared and distributed to shareholders
at least annually. The capital loss carryforward amount, if any, is available to
offset future net capital gains. Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of dividends and distributions from
net investment income and net realized capital gains are determined in
accordance with Federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. These book/tax
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the components of net assets based on their federal tax basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed earnings and profits for tax purposes are reported as
a tax return of capital.

As of July 31, 2004, the capital loss carryforwards, along with the related
expiration dates, are as follows:

<Table>

2010                          2011              2012              TOTAL

</Table>

As of January 31, 2005, the Fund's aggregate unrealized security gains and
losses based on cost for U.S. Federal income tax purposes are as follows:

<Table>
                                   
Tax cost                              $  125,163,531

- ----------------------------------------------------
   Net unrealized security loss       $   (1,215,350)
====================================================
</Table>

The difference between book-basis and tax-basis unrealized gains (losses) is
primarily attributable to wash sales and other temporary tax adjustments.

5.   PORTFOLIO SECURITIES TRANSACTIONS

Purchases and sales of investment securities (excluding short-term investments)
for the six months ended January 31, 2005 were as follows:

months ended January 31, 2005.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONCLUDED)

As of January 31, 2005 there were no securities on loan. In connection with the
securities lending program, State Street Bank & Trust Company ("SSB") received
fees of $259 for the six months ended January 31, 2005, which are netted against
Securities Lending Income on the Statement of Operations.

At their October 21, 2004 meeting, the Board of Directors voted to discontinue,
as soon as practicable, the Fund's participation in the SSB securities lending
program.

6.   TRUSTEES' REMUNERATION

The Fund's officers and the one Trustee who are associated with Lord Abbett do
not receive any compensation from the Fund for serving in such capacities.
Outside Trustees' fees are allocated among all Lord Abbett-sponsored funds based
on the net assets of each fund. There is an equity based plan available to all
outside Trustees under which outside Trustees must defer receipt of a portion
of, and may elect to defer receipt of an additional portion of Trustees' fees.
The deferred amounts are treated as though equivalent dollar amounts have been
invested proportionately in the funds. Such amounts and earnings accrued thereon
are included in Trustees' Fees on the Statement of Operations and in Trustees'
Fees Payable on the Statement of Assets and Liabilities and are not deductible
for U.S. Federal income tax purposes until such amounts are paid.

7.   EXPENSE REDUCTIONS

The Fund has entered into arrangements with its transfer agent and custodian
whereby credits realized as a result of uninvested cash balances are used to
reduce a portion of the Fund's expenses.

8.   LINE OF CREDIT

The Fund, along with certain other funds managed by Lord Abbett, has 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.
For the period August 1, 2004 through December 9, 2004, the fee for this
Facility was at an annual rate of .09%. Effective December 10, 2004, the
Facility was renewed at an annural rate of .08%. At January 31, 2005, there were
no loans outstanding pursuant to this Facility nor was the Facility utilized at
any time during the six months ended January 31, 2005.

9.   CUSTODIAN AND ACCOUNTING AGENT

SSB is the Fund's custodian and accounting agent. SSB performs custodian,
accounting and recordkeeping functions, relating to portfolio transactions and
calculating the Fund's NAV.

10.  INVESTMENT RISKS

The Fund is subject to the general risks and considerations associated with
equity investing as well as the particular risks associated with growth stocks.
The value of an investment will fluctuate in response to movements in the stock
market in general, and to the changing

                                                                              21

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONCLUDED)

prospects of individual companies in which the Fund invests. Different types of
stocks shift in and out of favor depending on market and economic conditions.
Growth stocks tend to be more volatile than other stocks. In addition, if the
Fund's assessment of a company's potential for growth or market conditions is
wrong, it could suffer losses or produce poor performance relative to other
funds, even in a rising market.

These factors can affect the Fund's performance.

HOUSEHOLDING

benefits you and other shareholders. If you need additional copies or do not
want your mailings to be "householded," please call Lord Abbett at 800-821-5129
or send a written request with your name, the name of your fund or funds and
your account number or numbers to Lord Abbett Family of Funds, P.O. Box 219336,
