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, 2016 through December 31, 2016).

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 Period 7/1/16 – 12/31/16” 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 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. 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.

	Value	Value	Period†
			7/1/16 -

Hypothetical (5% Return Before Expenses)	$1,000.00	$1,023.49	$1.81

^† For each class of the Fund, net expenses are equal to the annualized expense ratio for such class (0.35% for Classes A, C and I and 0.36% for Class B) multiplied by the average account value over the period, multiplied by 184/365 (to reflect one-half year period).

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. These securities are commonly known as money market instruments.

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 or Class C shares acquired through an exchange; and Class B shares redeemed before the sixth anniversary of purchase. Class B shares will automatically convert to Class A shares on the 25th day of the month (or, if the 25th day 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 Fund no longer issues Class B shares for purchase.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) 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. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	The Fund values securities utilizing the amortized cost method, which approximates fair value. Under the amortized cost 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 fair value due to the short duration of the issue.
(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 and are included in Interest and other income on the Statement of Operations. Investment income is allocated to each class of shares based upon the relative proportion of net assets at the beginning of

12

Notes to Financial Statements (unaudited)(continued)

	the day. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(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 filed U.S. federal tax returns remains open for the fiscal years ended June 30, 2013 through June 30, 2016. The statutes of limitations on the Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(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 fair value of these securities has declined, the 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 or transferring a liability 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 classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and 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

13

Notes to Financial Statements (unaudited)(continued)

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

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the six months then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Fund has a management agreement with 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 rate:

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

For the six months ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of 0.15% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

For the six month period ended December 31, 2016 Lord Abbett voluntarily waived a portion of the Fund’s management fee to the extent necessary to maintain a .02% annualized distribution yield for Class A, C and I shares and a .00% annualized distribution yield for Class B shares. In addition, Lord Abbett Distributor LLC (the “Distributor”) voluntarily reimbursed a portion of its Class B 12b-1 distribution fees in order to maintain a .00% annualized distribution yield, as described above. Such fee waivers and expense reimbursements are included in the Statement of Operations.

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, an affiliate of Lord Abbett. The following annual rates have been authorized by the Board pursuant to the plan:

Fees	Class A	Class B	Class C
Service	–	–	–
Distribution	–	.75%	–

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 six months ended December 31, 2016 and fiscal year ended June 30, 2016 was as follows:

	Six Months Ended 12/31/2016 (unaudited)		Year Ended 6/30/2016
Distributions paid from:
Ordinary income	$	70,025	$	140,324
Total distributions paid	$	70,025	$	140,324

5. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

Description	Gross Amounts of Recognized Assets		Gross Amounts Offset in the Statement of Assets and Liabilities		Net Amounts of Assets Presented in the Statement of Assets and Liabilities
Repurchase Agreements	$	103,470,776	$	–	$	103,470,776
Total	$	103,470,776	$	–	$	103,470,776

	Net Amounts
	of Assets		Amounts Not Offset in the
	Presented in		Statement of Assets and Liabilities
Counterparty	the Statement of Assets and Liabilities		Financial Instruments		Cash Collateral Received(a)		Securities Collateral Received(a)		Net Amount(b)
Fixed Income Clearing Corp.	$	3,470,776	$	–	$	–	$	3,470,776	$	–
J.P. Morgan Chase		100,000,000		–		–		100,000,000		–
Total	$	103,470,776	$	–	$	–	$	103,470,776	$	–

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

6. DIRECTORS’ REMUNERATION  

The Fund’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Fund for serving in such capacities. Independent Directors’ fees are

15

Notes to Financial Statements (unaudited)(continued)

allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent 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.

7. 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.

8. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission (“SEC”) issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the six months ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

9. 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 net asset value.

10. 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 the U.S. Government and by various government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation, 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. The Fund also may invest in repurchase agreements involving the securities described herein.

These factors can affect the Fund’s performance.

Shareholders could lose money by investing in the Fund. Although the Fund seeks to preserve the value of a shareholder’s investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and shareholders should not expect that the sponsor will provide financial support to the Fund at any time.

12. GOVERNMENT MONEY MARKET FUND STATUS  

The Fund intends to meet the definition of a “government money market fund” under SEC rule amendments that became effective October 14, 2016. Effective October 13, 2016, in accordance with this definition, the Board adopted an investment policy that the Fund invest at least 99.5% of its total assets in cash, government securities, and/or repurchase agreements that are collateralized fully by cash and/or government securities. The policy enabled the Fund to continue to operate with a stable net asset value per share. The Fund’s management does not believe that the new policy, the amendments, or related SEC rule amendments pertaining to money market funds had a significant impact on the Fund’s financial statements during the six months ended December 31, 2016.

17

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of the Fund’s benchmark; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) sales and redemption information for the Fund; (4) information regarding Lord Abbett’s financial condition; and (5) 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, and Lord Abbett’s commitment to compliance with all applicable 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 that may result from being engaged in other lines of business. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and the Fund’s benchmark as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was slightly below the median of the performance peer group for the one-year, three-year and five-year periods and below the median of the performance peer group for the ten-year period. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable.

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 of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology

18

Approval of Advisory Contract (continued)

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 compliance, administrative, and other services performed by Lord Abbett 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 level of the Fund and the expense levels of the expense peer group as of the date of each fund’s most recent annual report. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was above the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was not unreasonable in light of the factors it considered.

Profitability. The Board understood based on previous discussions with Lord Abbett’s management that the Fund, given the extent of Lord Abbett’s subsidization of the Fund, was not operating at a profit to Lord Abbett. The Board considered the amount of fees paid to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board considered the level of Lord Abbett’s operating margin in managing its mutual fund business and overall operating margin. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, adequately addressed any economies of scale in managing the Fund.

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 the 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 the 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 it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares of the Lord Abbett Funds. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but 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. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

19

Approval of Advisory Contract (concluded)

Alternative Arrangements. The Board considered whether, instead of approving continuation of the 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. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

Householding

The Fund has adopted a policy that allows it to send only one copy of the Fund’s prospectus, proxy material, annual report and semiannual report to certain shareholders residing at the same “household.” This reduces Fund expenses, which benefits you and other shareholders.
