                                 A Tradition of
                      Performance

"Lord Abbett Developing Growth Fund's transformation can be considered a
success. Manager Stephen McGruder...has transformed it into one of the best
funds in the small-cap growth category. The fund is an aggressive small-cap
vehicle delivering the kind of performance investors should expect."

Do Small-Cap Stocks Have            Just as there are different types of        
a Place in Your Portfolio?          investors--with unique goals, strategies and
                                    time horizons--there are different types of 
                                    securities to help them pursue their        
                                    objectives. Look at equities: stocks of     
                                    large-cap companies (market capitalizations 
                                    in excess of $5 billion) behave differently 
                                    than stocks of small-cap companies (market  
                                    capitalizations of $1 billion or less).     
                                    Year-to-year volatility is higher for       
                                    small-cap stocks, but, as the chart below   
                                    illustrates, small company stocks have      
                                    provided double-digit average annual returns
                                    during each of the last six decades.

                                    Lord Abbett Developing Growth Fund invests
                                    in stocks of small, developing companies.
                                    These stocks offer unusual growth potential
                                    and, not surprisingly, entail more investor
                                    risk. However, when used as part of a
                                    diversified portfolio, small-cap stocks may
                                    provide investors with added growth
                                    potential to help them achieve their goals.

CHAIRMAN

AUGUST 12, 1998

"Our belief is that the current environment is a normal phase of the investment
cycle...and one that creates a particularly attractive opportunity for small-cap
stocks."

Lord Abbett Developing Growth Fund completed the first half of its fiscal year
on July 31, 1998, with net assets of $944 million. Below is an overview of
class-specific data for the period.

<TABLE>

</TABLE>

Small-cap investors saw positive returns early in the period erased by a
downturn. This downturn was caused in part by a "flight to quality" due to
international monetary and economic crises as well as political problems that
led investors to seek more liquid investments, such as larger company stocks and
higher-quality bonds, than are generally found in the small-cap arena. In
August, after the close of the first half of the Fund's fiscal year, stocks in
general, and small-cap stocks in particular, suffered further price declines.
Our belief is that the current environment is a normal phase of the investment
cycle that has been exacerbated by the confluence of the above problems, and one
that creates a particularly attractive opportunity for small-cap stocks. In this
environment, your Fund's management team continued to focus on individual stock
selection with an emphasis on fundamental research.

Our focus on bottom-up stock selection allowed the Fund to overcome
industry-specific difficulties. For example, our slight overweighting in
software companies helped us reduce technology shortfalls that resulted when
earnings expectations were not met, predominantly by hardware companies. Our
strategy and philosophy remain constant as we concentrate on selecting those
companies that we believe will offer our investors superior long-term stock
price appreciation regardless of industry-specific problems or large-scale
economic trends.

We believe small-cap stocks will benefit from the economy's continued, albeit
slower, growth amid a moderate inflation environment. Given recent concerns over
the Far East and Russian economies, we regard the Fund's focus on companies
primarily involved in domestic commerce as a positive factor going forward. In
keeping with historical trends, we expect small-cap stocks to outperform large
caps over the long term.

Thank you for your continued confidence in Lord Abbett Developing Growth Fund.
We look forward to maintaining our relationship with you in the coming years and
helping you achieve your financial goals.

Focus on. . .Performance

The Benefits of Long-Term Investing

Lord Abbett Developing Growth Fund has enabled investors to participate in the
growth potential of small company stocks. During the past 10 years, the Fund has
performed well relative to its benchmark, the Russell 2000 Index.(1)

Growth of a $100,000 Fund Investment: 7/31/88-7/31/98

               Russell 2000        Fund
7/31/88        $100,000           $100,000           
1/31/89        $103,840           $101,841 
1/31/90        $105,470           $101,457 
1/31/91        $101,473           $116,326 
1/31/92        $146,913           $164,633 
1/31/93        $166,364           $160,836 
1/31/94        $197,291           $187,223 
1/31/95        $185,434           $182,086 
1/31/96        $240,971           $273,532 
1/31/97        $286,635           $351,069 
1/31/98        $338,430           $436,692 
7/31/98        $331,594           $442,986 


The Fund's results reflect a Class A share investment of $100,000 at net asset
value with dividends and capital gains reinvested. The Fund's results do not
include the effect of sales charges.

(1)   The Russell 2000 Index measures small company stock market performance,
      does not reflect the deduction of fees or expenses, is unmanaged and is
      not available for direct investment.

The Fund Versus the Benchmarks

As shown in the charts below, over the last 3- and 5-year periods ended 7/31/98,
Lord Abbett Developing Growth Fund consistently outperformed the Lipper Average
of Small Cap Funds (a benchmark consisting of funds that invest primarily in
companies with market capitalizations less than $1 billion).(2) Furthermore,
over these periods, the Fund outpaced the Russell 2000 Index, an unmanaged index
that measures small company stock market performance.(3) While historically
long-term investors in small company stocks have been rewarded with strong
returns (see charts on inside front cover), there is no assurance of the Fund's
future performance or that this pattern will continue.

Impressive Total Returns

   [The following table was depicted as a bar chart in the printed material.]

                                          3 Years           5 Years
                                          -------           -------
The Fund                                    19.2%             22.8%
Lipper Average of Small Cap Funds           14.1%             14.9%
Russell 2000 Index(3)                       13.4%             13.8%

The Fund's total returns represent the percent change in net asset value for
Class A shares over the 3- and 5-year periods ended 7/31/98 and reflect the
reinvestment of all distributions. The Fund's results do not include the effect
of sales charges. For performance at the Class A share maximum sales charge, see
the inside front cover.

      and is not available for direct investment.

Focus on. . .Small, Growing Companies

The Fund seeks to invest in companies that have passed through their initial,
formative years and are now in the "developing growth" phase, as illustrated in
the graph below. These companies have not yet matured, nor have they settled
into the slower growth rate of more established businesses. Because it is
arithmetically easier to grow from a small base than a large one, developing
growth companies may offer better opportunity for appreciation over the long
term. However, the stock prices of these companies can fluctuate sharply. That's
why Lord Abbett Developing Growth Fund makes sense for investors who want to
participate in the aggressive growth potential of a diversified, actively
managed small company stock portfolio.

The actual growth of a company cannot be foreseen, and it may be difficult to
determine in which phase a company is presently situated. There is no fixed
correlation between the business growth of a company and the market value of its
stock. The illustration below is not a representation of the performance of the
stocks in which the Fund invests.

Four Phases of Business Growth

1. Formative

Companies are in their infancy, a high-risk period.

2. Developing Growth

An evolving period, often characterized by a dramatic rate of growth; not
without risk.

3. Established Growth

Competitive forces and regulations tend to slow companies' progress.

4. Maturity

Companies' growth patterns tend to resemble the Gross Domestic Product.


Invest in the Future. . .Today

One hundred years ago, if you wanted to go from San Francisco to Paris, you
would have had to travel by train to New York, then board a ship to France, and
then another train to Paris. This could take up to two weeks.

Today, you could jet directly from San Francisco to Paris in 10 hours, or travel
faster than the speed of sound aboard an SST. Of course, you could also take a
train, hop a bus or take a scenic drive cross-country before boarding a
transatlantic flight--or cruise ship--to any major European destination.

Times have changed. We all have more choices than ever before. This applies to
transportation, as well as technology, education, medical and health care,
communications, retail purchasing, entertainment and business.

The Fund attempts to invest in companies that are leaders in their fields,
innovators, choice-makers. These small, growing companies often are creating
products and services that will fit many different lifestyles and needs.

Investing in Lord Abbett Developing Growth Fund is investing in the future.
Invest in the future, today.

A Note About Year 2000 Matters

As you probably know, the Fund depends on the proper functioning of computer
systems for most, if not all, aspects of its operations. Many computer systems
now in use cannot distinguish between the year 2000 (Y2K) and the year 1900, an
inability that could disrupt the services provided to the Fund.

Lord Abbett, Lord Abbett Distributor, the Fund's transfer agent and the Fund's
custodian all have advised the Fund that they have been actively working on
changes to their computer systems to prepare for the Year 2000 and expect that
their systems, and those of their outside service providers, will be adapted in
time. Although the Y2K issue is unprecedented and we have not yet completed our
evaluation of Y2K preparedness, we presently believe that there will be no
material effect on the Fund and its financial statements.


                                                                               3

Important Information

Investments in common stocks are subject to market fluctuations, providing the
potential for gain and the risk of loss. Lord Abbett Developing Growth Fund
invests in the securities of small-cap companies. Small-cap companies typically
have a higher risk of failure, and such companies' securities historically have
experienced a greater degree of illiquidity and market volatility than
securities of large-cap companies.

Results quoted on the previous pages represent past performance and reflect
appropriate Rule 12b-1 Plan expenses from commencement of the Plan. Tax
consequences are not reflected. The Fund's current sales charge structure has
changed from the past. The Russell 2000 Index is an unmanaged index that
measures small company stock market performance. Performance figures for the
unmanaged Russell 2000 Index do not reflect deduction of transaction costs or
management fees. An investor cannot invest directly in an index, such as the
Russell 2000 Index. The Fund issues additional classes of shares with distinct
pricing options. For a full discussion of the differences in pricing
alternatives, please call 800-874-3733 and ask for the Fund's current
prospectus. If used as sales material after 9/30/98, this report must be
accompanied by Lord Abbett's Performance Quarterly for the most recently
completed calendar quarter.

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
Company'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
if it is determined that such price more accurately reflects the value of such
securities. Short-term securities are valued at amortized cost (which
approximates market value) if the maturity is 60 days or less at the time of
purchase, or market value if the maturity is greater than 60 days. Securities
for which market quotations are not available are valued at fair value under
procedures approved by the Board of Directors. (b) It is the policy of the
Company 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
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. (d) A portion of the proceeds from sales and costs of repurchases of
capital 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.

2. Management Fee and Other Transactions with Affiliates The Company has a
management agreement with Lord, Abbett & Co. ("Lord Abbett") pursuant to which
Lord Abbett supplies the Company 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, statistical work and the supervision of the Company's
investment portfolio. The management fee is based on average daily net assets
for each month at the annual rate of 0.75% of the Company's first $100 million
of average daily net assets and 0.50% of such assets over $100 million.

The Company has Rule 12b-1 plans and agreements (the "Class A, Class B, Class C
and Class P Plans") with Lord Abbett Distributor LLC ("Distributor"), an
affiliate of Lord Abbett. The Company makes payments to Distributor which uses
or passes on such payments to authorized institutions. Pursuant to the Class A
Plan, the Company pays Distributor (1) an annual service fee of 0.15% of the
average daily net asset value of shares sold prior to June 1, 1990 and 0.25% of
the average daily net asset value of shares sold on or after that date, (2) a
one-time distribution fee of up to 1% on certain qualifying purchases and (3) a
supplemental annual distribution fee of 0.10% of the average daily net asset
value of Class A shares serviced by certain qualifying institutions. Pursuant to
the Class B Plan, the Company 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, the Company
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,
the Company 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 Plan.

Distributor received $505,598 representing payment of commissions on sales of
Class A shares after deducting $3,205,984 allowed to authorized distributors as
concessions. Certain of the Company's officers and directors have an interest in
Lord Abbett.

3. Distributions Net realized gain from investment transactions is distributed
to shareholders annually. Accumulated undistributed net realized gain at July
31, 1998 for financial reporting purposes aggregated $31,871,987.

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.

4. Capital The Company has authorized 1 billion shares of $.001 par value
capital stock designated as follows: Class A-895 million shares, Class B-20
million shares, Class C-25 million shares, Class P-30 million shares and Class
