Sieg, Director, President and Chief Executive Officer of the Lord Abbett Funds.<br>| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Dear Shareholders:** We are pleased to provide you with this semiannual report for Lord Abbett U.S. Government & Government Sponsored Enterprises Money Market Fund for the six-month period ended December 31, 2022. For additional information about the Fund, please visit our website at www.lordabbett.com. General information about Lord Abbett mutual funds, as well as in-depth discussions of market trends and investment strategies, is also provided in *Lord Abbett Insights*, a quarterly newsletter available on our website.<br> Thank you for investing in Lord Abbett mutual funds. We value the trust that you place in us and look forward to serving your investment needs in the years to come.<br>**Best regards,**<br>![](x3_c105261x3x2.jpg)<br> **Douglas B.

**Expense Example**

As a shareholder of the Fund you incur ongoing costs, including management fees; distribution and service (12b-1) fees, if applicable, 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, 2022 through December 31, 2022).

**Actual Expenses**

For each class of the Fund, the first line of the 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 7/1/22 – 12/31/22" 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.

------

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.

**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. These securities are commonly known as money market instruments.

The Fund operates as a government money market fund under Rule 2a-7 under the Act.

The Fund has three active share classes: Classes A, 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. Class C shares 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 month on which the purchase order was accepted, provided that the Fund or financial intermediary through which a shareholder purchased Class C shares has records verifying that the C shares have been held at least eight years.

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"), the Board has designated the determination of fair value of the Fund's portfolio investments to Lord, Abbett & Co. LLC ("Lord Abbett"), as its valuation designee. Accordingly, Lord Abbett is responsible for, among other things, assessing and managing valuation risks, establishing, applying and testing fair value methodologies, and evaluating pricing services. Lord Abbett has formed a Pricing Committee that performs these responsibilities on behalf of Lord Abbett, administers the pricing and valuation of portfolio investments and ensures that prices utilized reasonably reflect fair value. Among other things, these procedures allow Lord Abbett, subject to Board oversight, 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 in accordance with Rule 2a-7 under the Act. 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 amortized cost, which approximates fair value due to the short duration of the issue. |

---

**Notes to Financial Statements (continued)**

---

| | |
|:---|:---|
| (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, if applicable, 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 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 filed U.S. federal tax returns remains open for the fiscal years ended June 30, 2019 through June 30, 2022. 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. |
| (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 |

---

**Notes to Financial Statements (continued)**

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: <br>

• 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).

---

| |
|:---|
| A summary of inputs used in valuing the Fund's investments as of December 31, 2022 and, if applicable, 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. 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 provides 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 .15% of the Fund's daily average net assets. The management fee is accrued daily and payable monthly.

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. The fund administration fee is accrued daily and payable monthly. Lord Abbett voluntarily waived $3,362 of fund administration fee during the six months ended December 31, 2022.

**12b-1 Distribution Plan**

The Fund has adopted a distribution plan with respect to Class A and C shares pursuant to Rule 12b-1 under the Act, which provides for the payment of ongoing distribution and service fees to Lord Abbett Distributor LLC (the "Distributor"), an affiliate of Lord Abbett. The Board has not authorized any fees to date pursuant to the plan. The distribution and service fees are accrued daily and payable monthly.

Class I shares do not have a distribution plan.

One Director 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, 2022 and year ended June 30, 2022 was as follows:

**5.** **DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES** 

The Financial Accounting Standards Board 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 the 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:

<sup>(a)</sup> Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets (liabilities) presented in the Statement of Assets and Liabilities, for each respective counterparty.

<sup>(b)</sup> Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2022.

**6.** **DIRECTORS' REMUNERATION** 

The Fund's officers and one Director, who are associated with Lord Abbett do not receive any compensation from the Fund for serving in such capacities. Independent 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 Independent Directors under which Independent Directors may elect to defer receipt of a portion of Directors' fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the Fund. 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.

**Notes to Financial Statements (continued)**

**8.** **LINE OF CREDIT** 

For the period ended August 3, 2022, the Fund and certain other funds managed by Lord Abbett (collectively, the "Participating Funds") entered into a syndicated line of credit facility with various lenders for $1.275 billion (the "Syndicated Facility") whereas State Street Bank and Trust Company ("SSB") participated as a lender and as agent for the lenders. The Participating Funds were subject to graduated borrowing limits of one-third of fund net assets (if fund net assets are less than $750 million), $250 million, $300 million, $700 million, or $1 billion, based on past borrowings and likelihood of future borrowings, among other factors.

Effective August 4, 2022, the Participating Funds entered into a Syndicated Facility with various lenders for $1.625 billion whereas SSB participates as a lender and as agent for the lenders. The Participating Funds were subject to graduated borrowing limits of one-third of fund net assets (if fund net assets are less than $750 million), $250 million, $300 million, $700 million, or $1 billion, based on past borrowings and likelihood of future borrowings, among other factors.

For the period ended August 3, 2022, the Participating Funds were party to an additional line of credit facility with SSB for $330 million (the "Bilateral Facility"), $250 million committed and $80 million uncommitted. Under the Bilateral Facility, the Participating Funds are subject to graduated borrowing limits of one-third of fund net assets (if net assets are less than $750 million), $250 million, $300 million, or $330 million, based on past borrowings and likelihood of future borrowings, among other factors.

Effective August 4, 2022, the Participating Funds are party to an additional uncommitted line of credit facility with SSB for $330 million. Under the Bilateral Facility, the Participating Funds are subject to borrowing limits of one-third of fund net assets (if net assets are less than $750 million), or $250 million based on past borrowings and likelihood of future borrowings, among other factors.

The Syndicated Facility and the Bilateral Facility are to be used for temporary or emergency purposes as additional sources of liquidity to satisfy redemptions.

For the six months ended December 31, 2022 the Fund did not utilize the Syndicated Facility or Bilateral Facility.

**9.** **INTERFUND LENDING PROGRAM** 

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

For the six months ended December 31, 2022, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

**10.** **CUSTODIAN AND ACCOUNTING AGENT** 

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.

**Notes to Financial Statements (continued)**

**11.** **SECURITIES LENDING AGREEMENT** 

The Fund has established a securities lending agreement with Citibank, N.A. for the lending of securities to qualified brokers in exchange for securities or cash collateral equal to at least the market value of securities loaned, plus interest, if applicable. Cash collateral is invested in an approved money market fund. In accordance with the Fund's securities lending agreement, the market value of securities on loan is determined each day at the close of business and any additional collateral required to cover the value of securities on loan is delivered to the Fund on the next business day. As with other extensions of credit, the Fund may experience a delay in the recovery of its securities or incur a loss should the borrower of the securities breach its agreement with the Fund or the borrower becomes insolvent at a time when the collateral is insufficient to cover the cost of repurchasing securities on loan. Any income earned from securities lending is included in Securities lending net income on the Fund's Statement of Operations.

The initial collateral received by the Fund is required to have a value equal to at least 100% of the market value of the securities loaned. The collateral must be marked-to-market daily to cover increases in the market value of the securities loaned (or potentially a decline in the value of the collateral). In general, the risk of borrower default will be borne by Citibank, N.A.; the Fund will bear the risk of loss with respect to the investment of the cash collateral. The advantage of such loans is that the Fund continues to receive income on loaned securities while receiving a portion of any securities lending fees and earning returns on the cash amounts which may be reinvested for the purchase of investments in securities.

As of December 31, 2022, the Fund did not loan any securities.

**12.** **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 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. The Fund also may invest in repurchase agreements involving the securities described herein.

Geopolitical and other events (e.g., wars, terrorism, natural disasters, epidemics or pandemics such as the COVID-19 outbreak which began in late 2019) may disrupt securities markets and adversely affect global economies and markets, thereby decreasing the value of the Fund's investments. Market disruptions can also prevent the Fund from implementing its investment strategies and achieving its investment objective.

The transmission of COVID-19 and efforts to contain its spread have resulted in, among other things, border closings and other significant travel restrictions and disruptions, significant disruptions to business operations, supply chains and customer activity, lower consumer demand for goods and services, event cancellations and restrictions, service cancellations, reductions and other changes, significant challenges in healthcare service preparation and delivery, and prolonged quarantines, as well as general concern and uncertainty. The impact of the COVID-19 outbreak has,

**Notes to Financial Statements (concluded)**

and could again, negatively affect the global economy, the economies of individual countries, and the financial performance of individual issuers, sectors, industries, asset classes, and markets in significant and unforeseen ways.

The COVID-19 pandemic and its effects may last for an extended period of time. Although the long-term economic fallout of COVID-19 is difficult to predict, it has contributed to and is likely to continue to contribute to, market volatility, inflation and systemic economic weakness. The foregoing could disrupt the operations of the Fund and its service providers, adversely affect the value and liquidity of the Fund's investments, and negatively impact the Fund's performance and your investment in the Fund.

These factors, and others, can affect the Fund's performance.

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.

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 (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders.
