DOW CHAIRMAN - -------------------------------------------------------------------------------- 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 <Page> - -------------------------------------------------------------------------------- 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. 2 <Page> - -------------------------------------------------------------------------------- NOTE: 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. Please see section "Your Investment -- Purchases" in the propspectus for more information on redemptions that may be subject to a CDSC.

Information provided in this report should not be considered a recommendation to purchase or sell securities. A NOTE ABOUT RISK: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with the Fund, please see the Fund's prospectus. PERFORMANCE: BECAUSE OF ONGOING MARKET VOLATILITY, FUND PERFORMANCE MAY BE SUBJECT TO SUBSTANTIAL FLUCTUATION.

MUTUAL FUNDS ARE NOT INSURED BY THE FDIC, ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF, OR GUARANTEED BY BANKS, AND ARE SUBJECT TO INVESTMENT RISKS INCLUDING POSSIBLE LOSS OF PRINCIPAL AMOUNT INVESTED. 3 <Page> - -------------------------------------------------------------------------------- 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. 4 <Page> - -------------------------------------------------------------------------------- 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.

(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 <Page> 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. 16 <Page> 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 <Page> NOTES TO FINANCIAL STATEMENTS (CONCLUDED) 9.

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. 18 <Page> 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.
