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 (July 1, 2008 through December 31, 2008).

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 entitled "Expenses Paid During the Period 7/1/08 – 12/31/08" 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.

2

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.

^†  For each class of the Fund, expenses are equal to the annualized expense ratio for such class (0.70% for Class A, 1.34% for Class B, 0.73% for Class C and 0.71% for Class I) multiplied by the average account value over the period, multiplied by 184/365 (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 offers 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 aquired 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 25th day of the month (or, if the 25th is not a business day, the next business day thereafter) following the eighth anniversary of the day on which the purchase order was accepted.

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)  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 net income 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, 2006 through June 30, 2008. The statutes of limitations on the Fund's state and local tax returns may remain open for an additional year depending upon the jurisdiction.

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 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 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 dec lined, the Fund may incur a loss upon disposition of the securities.

(g)  Fair Value Measurements–The Fund adopted Financial Accounting Standards Board ("FASB") Statement No. 157, Fair Value Measurements ("SFAS 157"), effective July 1, 2008. In accordance with SFAS 157, 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. SFAS 157 established a three-tier hierarchy 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 ris k 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 – 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 risks associated with investing in those securities.

The following is a summary of the inputs used as of December 31, 2008 in valuing the Fund's investments carried at value:

Valuation Inputs	Investments in Securities
Level 2 – Other Significant Observable Inputs	$	717,569,924
Total	$	717,569,924

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:

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

For the six months ended December 31, 2008, the effective management fee paid to Lord Abbett was at an annualized rate of .46% of average daily net assets.

For the period July 1, 2007 through October 31, 2008, 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:

Class	% of Average Daily Net Assets
A		.70	%
B		1.45	%
C		.70	%
I		.70	%

For the period November 1, 2008 through October 31, 2009, Lord Abbett has contractually agreed to reimburse the Fund to the extent necessary so that each class' total annual operating expenses do not exceed the following annual rates:

Class	% of Average Daily Net Assets
A		.75	%
B		1.50	%
C		.75	%
I		.75	%

Effective November 1, 2008, Lord Abbett is voluntarily reimbursing a portion of the Fund's expenses so that the Fund's net expenses do not exceed an aggregate annualized rate of 0.70% of average daily net assets for Classes A, C and I shares and 1.45% of average daily net assets for Class B shares. In addition, beginning November 5, 2008, Lord Abbett voluntarily reimbursed expenses of the Fund's Class B shares. The aggregate of these reimbursements through December 31, 2008 was $23,454. Lord Abbett may stop its voluntary reimbursements or change the level of its reimbursements at any time.

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

15

Notes to Financial Statements (continued)

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	%		1.00	%

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

Class I does 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 six months ended December 31, 2008 and the fiscal year ended June 30, 2008 was as follows:

	Six Months Ended 12/31/2008 (unaudited)		Year Ended 6/30/2008
Distributions paid from:
Ordinary income	$	3,212,750	$	14,987,714
Total distributions paid	$	3,212,750	$	14,987,714

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 have 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 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 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.

16

Notes to Financial Statements (continued)

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, Federal Home Loan Bank 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.

Notes to Financial Statements (concluded)

10. RECENT ACCOUNTING PRONOUNCEMENTS

In March 2008, FASB issued Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities ("SFAS 161"), which is effective for fiscal years and interim periods beginning after November 15, 2008. SFAS 161 is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity's financial position, financial performance and cash flows. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statements and disclosures.

Approval of Advisory Contract

At meetings held on December 10 and 11, 2008, the Board, including all of the Directors who are not interested persons of the Fund or Lord Abbett, 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 Board also took into account its familiarity with Lord Abbett gained through its previous meetings and discussions, and the examination of the portfolio management team conducted by members of the Contract Committee during the year.

The materials received by the Board included, but were not limited to, (1) information provided by Lipper Inc. regarding the investment performance of the Fund compared to the investment performance of one or more groups of funds with substantially similar investment objectives (the "performance universe") and to the investment performance of an appropriate securities index for various time periods each ended September 30, 2008, (2) information on the effective management fee rates and expense ratios for one or more groups of funds with similar objectives and of similar size (the "peer expense 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, and (7) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund. In light of the recent volatility in the securities markets, the Board also considered the investment performance of the Fund for the period from September 30, 2008 through December 9, 2008.

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, and Lord Abbett's commitment to compliance with all relevant legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest resulting from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other.

Investment Performance and Compliance. The Board reviewed the Fund's investment performance in relation to that of the performance universe, both in terms of total return and in terms of other statistical measures. The Board observed that the investment performance of the Class A shares of the Fund was in the fourth quintile of its performance universe for the nine-month and ten-year periods, and in the third quintile for the one-year, three-year, and five-year periods. The Board also observed that the investment performance was lower than that of the Lipper U.S. Government Money Market Index for each of those periods.

Lord Abbett's Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover rates of Lord Abbett's investment management staff, Lord Abbett's investment methodology and philosophy, and Lord Abbett's approach to recruiting, training, and retaining

19

investment management personnel. The Board determined that Lord Abbett had the expertise and resources to manage the Fund effectively.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and Lord Abbett Distributor and the nature and extent of Lord Abbett's supervision of third party service providers, including the Fund's transfer agent and custodian.

Expenses. The Board considered the expense levels of the Fund and the expense levels of the peer expense group. It also considered the amount and nature of the fees paid by shareholders. The Board noted that it and Lord Abbett had agreed to an expense reimbursement agreement that limited the total expense ratios of Class A, Class C, and Class I to not more than 0.75% and the total expense ratio of Class B to not more than 1.45% through November 30, 2009, but that Lord Abbett did not propose to enter into an agreement, and instead intended to make voluntary reimbursements to keep the expenses of each class at the same level, which reimbursements it could end at any time. The Board observed that for the twelve months ended June 30, 2008 the contractual management and administrative services fees were approximately one basis point above the median of the peer group a nd the actual management and administrative services fees were approximately three basis points above the median of the peer group. The Board also observed that for the twelve months ended June 30, 2008 the total expense ratios of Class A and Class C were approximately two basis points above the median of the peer group, the total expense ratio of Class B was approximately eleven basis points above the median of the peer group, and the total expense ratio of Class I was approximately fifty basis points above the median of the peer group. The Board also observed that the Fund had a relatively high level of transfer agent and shareholder servicing costs, due to its relatively small average account size. The Board also considered what the expense ratio of each class likely would be if Lord Abbett did not reimburse any expenses and how each of those expense ratios would compare to those of the peer group.

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 personn el. The Board recognized that Lord Abbett's profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. The Board noted that Lord Abbett's overall profitability had decreased in fiscal 2008, largely due to declines in market prices and shareholder redemptions. The Board concluded that Lord Abbett's profitability overall and as to the Fund was not excessive.

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. The Board concluded that the existing advisory fee schedule, with its breakpoints in the level of the advisory fee, adequately addressed any economies of scale in managing the Fund.

20

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 advisory services. 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. The Board observed that Lord Abbett Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees from the Funds, and receives a portion of the sales charges on sales and redemptions of some classes of shares. The Board observed that, in addition, Lord Abbett accrues certain benefits for i ts business of providing investment advice to clients other than the Lord Abbett Funds, but that that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the management agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, 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 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.
