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

A. Continued interest rate hikes by the Federal Reserve Board (the Fed) and
worries about economic growth and inflation were the dominant factors affecting
the bond markets' performance.

     The Fed raised the fed funds rate eight times in the period. From a
starting level of 3.25%, the fed funds rate increased to 5.25% by June 30, 2006.
At the start, Fed policy was accommodative - that is, rates were low enough to
stimulate demand. But by the end of the period, policymakers indicated that the
lagged effect of the increases in interest rates was moderating economic growth.

     The change in policy stance was indicated by the trends in economic growth
and inflation pressures. Real gross domestic product (GDP) grew at an annual
rate of 2.9% in second half 2005, followed by a strong 5.6% increase in first
quarter 2006. The yearly inflation rate, as measured by the 12-month percent
change in the Consumer Price Index for all goods and services, rose from 2.5% in
June 2005 to 4.3% a year later. Core inflation, which excludes food and energy
costs, also accelerated.

     Because of the continued Fed tightening and higher inflation worries,
interest rates rose along the entire yield spectrum during the period. However,


                                                                               1

rates on securities maturing in two years or less increased more than did
longer-term securities. As a result, in February, March, and June, the average
yield on a two-year Treasury note was higher than the yield on a 10-year note,
resulting in an inverted yield curve.

Q. HOW DID THE FUND PERFORM IN THE YEAR ENDED JUNE 30, 2006?

A. The Fund (Class A shares) finished the year ended June 30, 2006, with total
net assets of $337.0 million and a seven-day current yield of 4.4%. 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 year ended June 30, 2006, the Fund returned 3.5%, reflecting
performance at the 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 3.4% in the same
period. AVERAGE ANNUAL RETURNS, WHICH INCLUDE THE REINVESTMENT OF ALL
DISTRIBUTIONS AS OF JUNE 30, 2006, ARE 1 YEAR: 3.51%, 5 YEARS: 1.41%, AND 10
YEARS: 3.06%.

     AN INVESTMENT IN MONEY MARKET FUNDS IS NEITHER INSURED NOR GUARANTEED BY
THE FEDERAL DEPOSIT INSURANCE CORP. 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.

     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.

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, 2006 through June 30,
2006).

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 1/1/06 - 6/30/06" 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.

     ratio for such class (0.70% for Class A, 1.45% for Class B, and 0.70% for
     Classes C & 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 there may be a
contingent deferred sales charge ("CDSC") 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 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.

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 simultaneously commits to resell that security
     to the seller (a bank or securities dealer) at an


                                                                              15

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     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 the Fund's average daily net assets at the
following annual rates:

..50% of the first $250 million of average daily net assets;
..45% of the next $250 million of average daily net assets;
..40% of average daily net assets over $500 million.

For the fiscal year ended June 30, 2006, the fee paid to Lord Abbett was at an
annual rate of .49% of average daily net assets.

For the fiscal year ended June 30, 2006, Lord Abbett contractually agreed to
reimburse the Fund to the extent necessary so that each class' total annual
operating expenses did not exceed the following annual rates:

           % OF AVERAGE DAILY
CLASS          NET ASSETS
- -----------------------------
A                  .70%
B                 1.45%
C                  .70%
Y                  .70%

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 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:

FEE                                            CLASS A(1)   CLASS B   CLASS C(1)
- --------------------------------------------------------------------------------
Service and distribution fee                       .15%       .75%       .25%

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

Class Y does not have a distribution plan.

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

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 U.S. 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 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.


                                                                              17

10.  RECENT ACCOUNTING PRONOUNCEMENT

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes - an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006. The Fund will
adopt FIN 48 during 2007 and the impact to the fund's financial statements, if
any, is currently being assessed.

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, 2006,
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, 2006 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, 2006, 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.

                    provided to the Lord Abbett Funds, including the Registrant,
                    and

               -    any audit-related, tax, and other services to be provided to

                    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.

          At the June 22, 2006 meetings of the Nominating and Governance
          Committees (the "Committee") of the Boards of each of the Lord Abbett
          Funds, the Committee adopted policies and procedures for the
          nomination of independent directors/trustees ("Procedures"). The
          Procedures provide criteria for the nomination of independent
          directors/trustees, as well as a process for identifying and
          evaluating candidates. With respect to shareholder recommendations, it
          is the Committee's policy to consider director/trustee nominations
          recommended by shareholders using the same criteria the Committee uses
          in considering potential director/trustee nominations from other
          sources. The Committee believes that directors/trustees must represent
          all shareholders and not just a limited set of shareholders. A copy of
          the Procedures may be found at www.LordAbbett.com.

ITEM 11:  CONTROLS AND PROCEDURES.

     (a)  Based on their evaluation of the Registrant's disclosure controls and
          procedures (as defined in Rule 30a-3(c) under the Investment Company
          Act of 1940) as of a date within 90 days prior to the filing date of
          this report, the Chief Executive Officer and Chief Financial Officer
          of the Registrant have concluded that such disclosure controls and
          procedures are reasonably designed and effective to ensure that
          material information relating to the Registrant, including its
          consolidated subsidiaries, is made known to them by others within
          those entities.

<Page>

     (b)  There were no significant changes in the Registrant's internal control
          over financial reporting (as defined in Rule 30a-3(d) under the
          Investment Company Act of 1940) that occurred during the second fiscal
          quarter of the period covered by this report that have materially
          affected, or are reasonably likely to materially affect, the
          Registrant's internal control over financial reporting.

     (a)(2) Certification of each principal executive officer and principal
          financial officer of the Registrant as required by Rule 30a-2 under
