ANNUAL REPORT
FOR THE FISCAL YEAR ENDED JUNE 30, 2005

DEAR SHAREHOLDERS: We are pleased to provide you with this overview of the Lord
Abbett U.S. Government & Government Sponsored Enterprises Money Market Fund's
strategies and performance for the fiscal year ended June 30, 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

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

A:  Under the weight of waning fiscal stimulus and rising energy prices, the
pace of economic growth, as measured by real gross domestic product (GDP),
slowed in the first half of 2005, to about a 3.7 percent annualized rate from a
4.4 percent rate in 2004. Contributing to this still above-trend growth rate of
economic activity, consumer spending during the first half grew slightly faster
than its 30-year average, business spending expanded at near double-digit rates,
while residential housing demand surged on continued declines in mortgage rates.
Although corporate fundamentals remained strong, this modest economic slowing,
rising energy prices, and increasing short-term interest rates raised investor
concerns such that in the six months through June 30, 2005, equities were caught
in a sea of confluences and drifted marginally lower.

    Perhaps the most significant development in the first half of 2005 was the
flattening of the yield curve (the distribution of Treasury bond yields across
maturities). Federal Reserve Board (the Fed) chairman Alan Greenspan referred to
the failure of long-term yields to adjust upward with the Fed's tightening
campaign as a "conundrum." Specifically, although the Fed raised short-term
rates by 100 basis points, long-term yields declined by about 25 basis points.
So, although the Fed desired to extract excess liquidity from the economy,
borrowing costs actually fell.

Q:  HOW DID THE FUND PERFORM OVER THE FISCAL YEAR ENDED JUNE 30, 2005?

A:  The fund (Class A shares) finished the fiscal year ended June 30, 2005, with
total net assets of $271.7 million and a seven-day current yield of 2.4 percent.
The current yield refers to the income generated by an investment in the fund
over a seven-day period, which is then annualized. The yield quotation more
closely reflects the current earnings of the fund than the one-year total return
quotation. For the fiscal year ended June 30, 2005, the fund returned 1.4
percent, reflecting performance at the

                                                                               1

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

net asset value (NAV) of Class A shares with all distributions reinvested,
compared with its peer group, the Lipper U.S. Government Money Market Funds
Average,(1) which returned 1.4 percent in same period. STANDARDIZED AVERAGE
ANNUAL RETURNS, WHICH INCLUDE THE REINVESTMENT OF ALL DISTRIBUTIONS AS OF JUNE
30, 2005, ARE: 1 YEAR: 1.35 PERCENT, 5 YEARS: 1.71 PERCENT, AND 10 YEARS: 3.20
PERCENT. During certain periods shown, expense reimbursements were in place.
Without such expense reimbursements, the fund's returns would have been lower.
Class A shares acquired through an exchange may be subject to a CDSC of 1
percent if the shares are redeemed within 12 months of the purchase.

AN INVESTMENT IN MONEY MARKET FUNDS IS NEITHER INSURED NOR GUARANTEED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY.
ALTHOUGH THE FUND SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. 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 TO THE MOST RECENT
MONTH-END BY CALLING LORD ABBETT AT 800-821-5129 OR REFERRING TO OUR WEBSITE AT
www.LordAbbett.com.

Q:  WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE?

A:  In general, fund yield kept pace with short-term interest rates. Consistent
with its goal of providing current income with minimum credit risk, the
portfolio remained invested in high-quality, short-term securities issued by the
U.S. Treasury and certain U.S. government agency securities. As rates rose, the
portfolio's average maturity was extended. The portfolio was concentrated in
specific areas of the money market yield curve that were expected to provide the
highest risk-adjusted yield.

    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.

                                                                               3

EXPENSE EXAMPLE

    As a shareholder of the fund you incur ongoing costs, including management
fees; distribution and service (12b-1) fees (currently only Class B shares have
an active 12b-1 Plan); 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 (January 1, 2005 through June 30,
2005).

ACTUAL EXPENSES

    For each class of the fund, the first line of the applicable table on the
following pages 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 1/1/05 - 6/30/05" 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 applicable table on the
following pages 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.

+ For each class of the Fund, expenses are equal to the annualized expense ratio
for such class (0.70% for Class A, 1.45% for Class B, 0.70% for Class C, and
0.70% for Class Y) multiplied by the average account value over the period,
multiplied by 181/365 (to reflect one-half year period).

NOTES TO FINANCIAL STATEMENTS

1.  ORGANIZATION

Lord Abbett U.S. Government & Government Sponsored Enterprises Money Market
Fund, Inc. (the "Fund"), is registered under the Investment Company Act of 1940
(the "Act") as a diversified, open-end management investment company. The Fund
was incorporated under Maryland law on May 9, 1979.

The investment objective of the Fund is to seek high current income and
preservation of capital through investments in high quality, short-term, liquid
securities.

The Fund offers four classes of shares: Classes A, B, C and Y. There are no
front end sales charges on shares of each class, although a contingent deferred
sales charge ("CDSC") may be applied to each class of shares as follows: Class A
shares acquired through an exchange and redeemed within 24 months (12 months if
shares were purchased on or after November 1, 2004) following the purchase made
without a sales charge; Class B shares redeemed before the sixth anniversary of
purchase; Class C shares redeemed before the first anniversary of purchase.

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-The Fund values securities utilizing the amortized cost
    method, which approximates market value. Under this method, all investments
    purchased at a discount or premium are valued by amortizing the difference
    between the original purchase price and maturity value of the issue over the
    period to maturity. Securities purchased at face value are valued at cost,
    which approximates 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.

(c) INVESTMENT INCOME-Interest income is recorded on the accrual basis.
    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 net income to its
    shareholders. Therefore, no federal income tax provision is required.

(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. Class B shares bear all expenses and fees related to
    the Class B 12b-1 distribution plan.

(f) 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

14
<Page>

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    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 those
    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
the following annual rates:

<Table>
                         
First $250 million          .50%
Next $250 million           .45%
Over $500 million           .40%
</Table>

Effective January 1, 2005, for the fiscal year ended June 30, 2005, Lord Abbett
contractually agreed to reimburse the Fund to the extent necessary so that each
class' net annual operating expenses do not exceed the following annualized
rates:

<Table>
<Caption>
CLASS            % OF AVERAGE DAILY NET ASSETS
- ----------------------------------------------
                                       
A                                          .70%
B                                         1.45%
C                                          .70%
Y                                          .70%
</Table>

For the six-month period ended December 31, 2004, Lord Abbett voluntarily
limited Class A, Class B, Class C, and Class Y expenses to an amount necessary
to maintain an annualized seven-day current yield of .20%.

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 (the "Plan") with respect to one or
more classes of shares pursuant to Rule 12b-1 of the Act, which provides for the
payment of 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>
<Caption>
FEE                                   CLASS A(1)    CLASS B     CLASS C(1)
- --------------------------------------------------------------------------
                                                          
Service and distribution fee             .15%         .75%         .25%
</Table>

(1) The Fund has has not activated its Class A and Class C Plans, and therefore,
    no payments are currently authorized under the Plans.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

4.  DISTRIBUTIONS

Dividends from net investment income are declared daily and paid monthly.

5.  DIRECTORS' REMUNERATION

The Fund's officers and the one Director who are associated with Lord Abbett do
not receive any compensation from the Fund for serving in such capacities.
Outside Directors' 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 Directors under which outside Directors must defer receipt of a
portion of, and may elect to defer receipt of an additional portion of
Directors' 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 Directors' Fees on the Statement of
Operations and in Directors' Fees Payable on the Statement of Assets and
Liabilities and are not deductible for Federal income tax purposes until such
amounts are paid.

6.  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.

7.  CUSTODIAN AND ACCOUNTING AGENT

State Street Bank & Trust Company ("SSB") is the Fund's custodian and accounting
agent. SSB performs custodial, accounting and recordkeeping functions relating
to portfolio transactions and calculating the Fund's NAV.

8.  INVESTMENT RISKS

The Fund's yield may vary in response to changes in interest rates and other
market factors.

The Fund generally invests a substantial portion of its assets in money market
securities issued by various government sponsored enterprises such as Federal
Home Loan Mortgage Corporation and Federal National Mortgage Association. Such
securities are not guaranteed by the U.S. Government, but are supported only by
the credit of the particular government sponsored enterprises involved, and by
the discretionary authority of the U.S. Treasury to purchase the enterprise
obligations. There is no assurance that the U.S. Government will provide
financial support to such enterprises.

An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.
Although the Fund seeks to preserve the value of an investment at $1.00 per
share, it is possible to lose money by investing in the Fund.

These factors can affect the Fund's performance.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD OF DIRECTORS AND SHAREHOLDERS,
LORD ABBETT U.S. GOVERNMENT & GOVERNMENT
SPONSORED ENTERPRISES MONEY MARKET FUND, INC.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Lord Abbett U.S. Government & Government
Sponsored Enterprises Money Market Fund, Inc. (the "Fund") as of June 30, 2005,
and the related statement of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the periods presented. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of June 30, 2005 by correspondence with the custodian. We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Lord
Abbett U.S. Government & Government Sponsored Enterprises Money Market Fund,
Inc. as of June 30, 2005, the results of its operations for the year then ended,
the changes in its net assets for each of the two years in the period then
ended, and the financial highlights for each of the periods presented, in
conformity with accounting principles generally accepted in the United States of
America.

APPROVAL OF ADVISORY CONTRACT

At a meeting on December 9, 2004, the Board of Directors of the Fund, including
all Directors who are not interested persons of the Fund (the "Board"),
considered whether to approve the continuation of the existing management
agreement between the Fund and Lord Abbett. In addition to the materials the
Board had reviewed throughout the course of the year, the Board received
materials relating to the management agreement before the meeting and had the
opportunity to ask questions and request further information in connection with
its consideration.

The materials received by the Board as to the Fund included, but were not
limited to, (1) information provided by Lipper Analytical Services, Inc.
regarding the investment performance of the Fund compared to the investment
performance of a group of funds with substantially similar investment objectives
(the "performance universe") and to the investment performance of an appropriate
securities index (if such an index existed), for various time periods each
ending September 30, 2004, (2) information on the effective management fee rates
and expense ratios for funds with similar objectives and similar size (the "peer
group"), (3) sales and redemption information for the Fund, (4) information
regarding Lord Abbett's financial condition, (5) an analysis of the relative
profitability of the management agreement to Lord Abbett, (6) information
regarding the distribution arrangements of the Fund, (7) information regarding
the personnel and other resources devoted by Lord Abbett to managing the Fund.

INVESTMENT MANAGEMENT SERVICES GENERALLY. The Board considered the investment
management services provided by Lord Abbett to the Fund, including investment
research, portfolio management, and trading. The Board noted that Lord Abbett
did not use brokerage commissions to purchase third-party research.

INVESTMENT PERFORMANCE AND COMPLIANCE. The Board reviewed the Fund's investment
performance as well as the performance of the performance universe of funds,
both in terms of total return and in terms of other statistical measures. The
Board noted that the performance of the Class A shares of the Fund was in the
fourth quintile of its performance universe in the nine-month and one-year
periods and in the fifth quintile in the three-, five-, and ten-year periods.
The Board also noted that the performance was below that of the Lipper U. S.
Government Money Market Index for each period.

LORD ABBETT'S PERSONNEL AND METHODS. The Board considered the qualifications of
the personnel providing investment management services to the Fund, in light of
the Fund's investment objective and discipline. Among other things, they
considered the size and experience of Lord Abbett's investment management staff,
Lord Abbett's investment methodology and philosophy, and Lord Abbett's approach
to recruiting, training, and retaining investment management personnel.

NATURE AND QUALITY OF OTHER SERVICES. The Board considered the nature, quality,
costs, and extent of administrative and other services performed by Lord Abbett
and Lord Abbett Distributor and the nature and extent of Lord Abbett supervision
of third party service providers, including the Fund's transfer agent and
custodian.

EXPENSES. The Board considered the expense ratios of the class and the expense
ratios of peer groups. It also considered the amount and nature of the fees paid
by shareholders. The Board noted that the contractual management and
administrative services fees were approximately six basis points above the
median of the peer group, and that the actual management and

24
<Page>

administrative services fees were approximately eight basis points above the
median. The Board also noted that the total expense ratio of Classes A and C
were approximately twelve basis points above the median of the peer group and
the total expense ratio of Class B was approximately the same as the median. The
Board also noted that Lord Abbett had reimbursed thirteen basis points of
expenses during the most recent 12 months. The Board noted in addition that the
Fund had relatively high transfer agent and shareholder servicing costs compared
to many of its peers. The Board noted that Lord Abbett proposed to implement a
total expense cap for the Fund that would reduce the total expense ratios of
Classes A, C, and Y to 0.75% and the total expense ratio of Class B to 1.50%.
The Board noted that the total expense ratio of Classes A, C, and Y would be
approximately four basis points above the median of the peer group.

The Board conducted additional discussions with Lord Abbett regarding the
expense levels of the Fund and the Fund's historical performance. Following
those discussions, Lord Abbett agreed to implement a total expense cap for the
Fund that would reduce the total expense ratio of each class of shares by an
additional five basis points, so that the expense ratio of Classes A, C, and Y
would not exceed 0.70% and the total expense ratio of Class B would not exceed
1.45%.

PROFITABILITY. The Board considered the level of Lord Abbett's profits in
managing the Fund, including a review of Lord Abbett's methodology for
allocating its costs to its management of the Fund. The Board concluded that the
allocation methodology had a reasonable basis and was appropriate. It considered
the profits realized by Lord Abbett in connection with the operation of the Fund
and whether the amount of profit was fair for the management of the Fund. The
Board also considered the profits realized from other businesses of Lord Abbett,
which may benefit from or be related to the Fund's business. The Board
considered Lord Abbett's profit margins in comparison with available industry
data, both accounting for and ignoring marketing and distribution expenses, and
how those profit margins could affect Lord Abbett's ability to recruit and
retain investment personnel. The Board noted that Lord Abbett's profitability
had increased, in part due to an increase in assets under management.

ECONOMIES OF SCALE. The Board considered whether there had been any economies of
scale in managing the Fund, whether the Fund had appropriately benefited from
any such economies of scale, and whether there was potential for realization of
any further economies of scale.

OTHER BENEFITS TO LORD ABBETT. The Board considered the character and amount of
fees paid by the Fund and the Fund's shareholders to Lord Abbett and Lord Abbett
Distributor for services other than investment. The Board also considered the
revenues and profitability of Lord Abbett's investment advisory business apart
from its mutual fund business, and the intangible benefits enjoyed by Lord
Abbett by virtue of its relationship with the Fund.

ALTERNATIVE ARRANGEMENTS. The Board considered whether, instead of approving
continuation of the management agreement, employing one or more alternative
arrangements might be in the best interests of the Fund, such as continuing to
employ Lord Abbett, but on different terms.

In considering whether to approve the continuation of the management agreement,
the Board did not identify any single factor as paramount or controlling. This
summary does not discuss in detail all matters considered. After considering all
of the relevant factors, the Board then unanimously found that continuation of
the existing management agreement was in the best interests of the Fund and its
shareholders and voted unanimously to approve the continuation of the management
agreement.

                                                                              25

(e) (1) Pursuant to Rule 2-01(c) (7) of Regulation S-X, the Registrant's Audit
Committee has adopted pre-approval policies and procedures. Such policies and
procedures generally provide that the Audit Committee must pre-approve:

               -    any audit, audit-related, tax, and other services to be
                    provided to the Lord Abbett Funds, including the Registrant,
                    and

               -    any audit-related, tax, and other services to be provided to
                    the Registrant's investment adviser and any entity
                    controlling, controlled by or under common control with the
                    investment adviser that provides ongoing services to one or
                    more Funds comprising the Registrant if the engagement
                    relates directly to operations and financial reporting of a
                    Fund, by the independent auditor to assure that the
                    provision of such services does not impair the auditor's
                    independence.

The Audit Committee has delegated pre-approval authority to its Chairman,
subject to a fee limit of $10,000 per event, and not to exceed $25,000 annually.
The Chairman will report any pre-approval decisions to the Audit Committee at
its next scheduled meeting. Unless a type of service to be provided by the
independent auditor has received general pre-approval, it must be pre-approved
by the Audit Committee. Any proposed services exceeding pre-approved cost levels
will require specific pre-approval by the Audit Committee.

entity controlling, controlled by or under common control with the investment

determined that the provision of such services is compatible with maintaining
