Sponsored Enterprises Money Market Fund

Annual Report

For the fiscal year ended June 30, 2010

From left to right: Robert S. Dow, Director and Chairman of the Lord Abbett Funds; E. Thayer Bigelow, Independent Lead Director of the Lord Abbett Funds; and Daria L. Foster, Director and President of the Lord Abbett Funds.

The last 12 months have been an especially interesting time for money market funds, with yields on money market securities remaining at record-low levels. Since the end of 2008, the Federal Reserve Board has kept the fed funds interest rate at historically low levels making it difficult for money market funds to maintain a positive yield and generate income above fund expenses.

In response to the financial crisis and its impact on certain money market funds, the U.S. Securities and Exchange Commission (SEC) recently adopted several amendments to Rule 2a-7 under the Investment Company Act of 1940, which governs money market funds. The amendments are intended to: (i) strengthen the risk-limiting conditions under Rule 2a-7, including the addition of new liquidity requirements; (ii) enhance portfolio information disclosure; and (iii) improve fund operations.

The SEC rules are intended to increase the resilience of money market funds to economic stresses and to reduce the risks of sizable withdrawals from the funds by shortening maturity limits, increasing credit quality standards, and imposing new liquidity and enhanced disclosure requirements. By enforcing greater restrictions on the types of securities in which money market funds can invest, the SEC is trying to reduce the possibility of any money market fund “breaking the buck.”

The Fund had already complied with a number of new rules before they took effect in May 2010, and is committed to comply with the others. Lord Abbett is supportive of these policies, which are meant to strengthen the money market industry and protect investors.

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

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, 2010 through June 30, 2010).

Actual Expenses

For each class of the Fund, the first line of the applicable 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 titled “Expenses Paid During the Period 1/1/10 – 6/30/10” 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 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 (loads). 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.

	Beginning Account Value		Ending Account Value		Expenses Paid  During Period†
	1/1/10		6/30/10		1/1/10 - 6/30/10
Class A

^† For each class of the Fund, net expenses are equal to the annualized expense ratio for such class (0.13% for Classes A, C and I and 0.15% for Class B) 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, as amended (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 has four classes of shares: Classes A, B, C and I. There are no front-end sales charges on shares of each class, although there may be a contingent deferred sales charge (“CDSC”) applied to a class of shares as follows: certain redemptions of Class A shares acquired through an exchange; 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 automatically convert to Class A shares on the 25^th day of the month (or, if the 25^th is not a business day, the next business day thereafter) following the eighth anniversary of the day the purchase order was accepted. On March 31, 2010, the Fund no longer made Class B shares available for 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 as earned. 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) Income 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 income tax provision is required.

The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s U.S. federal tax returns remains open for the fiscal years ended June 30, 2007 through June 30, 2010. The statutes of limitations on the Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

12

Notes to Financial Statements (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. Class B shares bear all expenses and fees relating to the Fund’s 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 a 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, a Fund may incur a loss upon disposition of the securities.

(g) Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk - for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below:

• Level 1 – unadjusted quoted prices in active markets for identical investments;

• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and

• Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of June 30, 2010 in valuing the Fund’s investments carried at value:

Investment Type	Level 1		Level 2		Level 3		Total

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, 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:

First $250 million	.50%
Next $250 million	.45%
Over $500 million	.40%

For the fiscal year ended June 30, 2010, the effective management fee, before waivers and expenses reimbursed, was at an annualized rate of .46% of the Fund’s average daily net assets.

For the period July 1, 2009 through June 30, 2010, Lord Abbett voluntarily agreed to waive all or a portion of its management fee and, if necessary, reimburse expenses so that total net annual operating expenses did not exceed an annual rate of .70% of average daily net assets for Class A, C and I shares and 1.45% of average daily net assets for Class B shares⁽¹⁾. In addition, Lord Abbett voluntarily agreed to waive a portion of the Fund’s management fee and, if necessary, reimburse expenses to the extent necessary so Class A, C and I shares maintain a 0.02% annualized distribution yield, and Class B shares maintain a 0.00% annualized distribution yield. For the fiscal year ended June 30, 2010, Lord Abbett waived its entire management fee of $2,791,572 and reimbursed other expenses of $1,008,497. For the fiscal year ended June 30, 2010, Lord Abbett Distributor LLC (the “Distributor”) reimbursed Class B 12b-1 fees of $310,642.

Lord Abbett may stop or change the level of the voluntary waiver or reimbursement at any time.

⁽¹⁾ For the period July 1, 2009 through October 31, 2009, Lord Abbett contractually agreed to reimburse the Fund to the extent necessary so that each class’ total annual operating expenses did not exceed annual rates of .75% of average daily net assets for Class A, C and I shares and 1.50% of average daily net assets for Class B shares.

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 Plan

The Fund has adopted a distribution plan with respect to Class A, B and C shares pursuant to Rule 12b-1 under the Act, which provides for the payment of ongoing distribution and service fees to the Distributor. The fees are accrued daily at annual rates based upon the Fund’s average daily net assets as follows:

Fees	Class  A(1)	Class B	Class  C(1)
Service and distribution fee	.15%	.75%	1.00%

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

Class I shares do not have a distribution plan.

Two Directors and certain of the Fund’s officers have an interest in Lord Abbett.

4.    DISTRIBUTIONS

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

The tax character of distributions paid during the fiscal years ended June 30, 2010 and 2009 was as follows:

	Year Ended 6/30/2010		Year Ended 6/30/2009
Distributions paid from:
Ordinary income	$	112,258	$	3,293,151
Total distributions paid	$	112,258	$	3,293,151

5.    DIRECTORS’ REMUNERATION

The Fund’s officers and the two Directors 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 had been invested 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 an arrangement 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 and 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, the Federal Home Loan Banks 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’s obligations. There is no assurance that the U.S. Government will provide financial support to enterprises that are not supported by the full faith and credit of the U.S. Government.

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

To the Shareholders and Board of Directors of Lord Abbett U.S. Government & Government Sponsored Enterprises Money Market Fund, Inc.:

We have audited the accompanying statement of assets and liabilities of Lord Abbett U.S. Government & Government Sponsored Enterprises Money Market Fund, Inc. (the “Fund”), including the schedule of investments, as of June 30, 2010, 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 five years in the period then ended. 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 the 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, 2010, by correspondence with the custodian and brokers. 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, 2010, 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 five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.
