**Notes to Financial Statements (unaudited)**

&nbsp;&nbsp;&nbsp;&nbsp;**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 "1940 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 1940 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 Class C shares have been held at least eight years.

**Basis of Preparation**

The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946 Financial Services - Investment Companies*.* The preparation of the financial statements in conformity with generally accepted accounting principles 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.

**Segment Reporting**

An operating segment is defined in FASB Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures ("ASU 2023-07") as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity's chief operating decision maker ("CODM") to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available.

The CODM for the Fund is Lord, Abbett & Co. LLC ("Lord Abbett") through its Management, Investment and Operating Committees, which are responsible for assessing performance and making decisions about resource allocation. The CODM has determined that the Fund has a single operating segment based on the fact that the CODM monitors the operating results of the Fund as a whole and that the Fund's long-term strategic asset allocation is pre-determined in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Fund's portfolio managers as a team. The financial information provided to and reviewed by the CODM is consistent with that presented within the Fund's Schedule of Investments, Statement of Assets and Liabilities, Statement of Operations, Statements of Changes in Net Assets and Financial Highlights.

&nbsp;&nbsp;&nbsp;&nbsp;**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 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 (the "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 1940 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. |
|  | 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: |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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).

**Notes to Financial Statements (unaudited)(continued)**

---

| | |
|:---|:---|
|  | A summary of inputs used in valuing the Fund's investments as of December 31, 2025 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. |
| (b) | 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. |
| (c) | 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. |
|  | Management has reviewed the Fund's tax positions for all open tax years and has determined that as of December 31, 2025, no liability for Federal Income tax is required in the Fund's financial statements for net unrecognized tax benefits. However, management's conclusions may be subject to future review based on changes in, or the interpretation of, the accounting standards or tax laws and regulations. The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The Fund's Federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. The statutes of limitations on the Fund's state and local tax returns may remain open for an additional year depending upon the Fund's jurisdiction. |
| (d) | Investment Income–Dividend income, if any, is recorded on the ex-dividend date. 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, in 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. |
| (e) | 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. |
|  | Due to the absence of a master netting agreement related to the Fund's participation in repurchase agreements, no offsetting disclosures have been made on behalf of the Fund. |
| (f) | 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. |

**Notes to Financial Statements (unaudited)(continued)**

&nbsp;&nbsp;&nbsp;&nbsp;**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 accrued daily and payable monthly.

The management fee is 0.15% of the Fund's daily average 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. The fund administration fee is accrued daily and payable monthly. Lord Abbett voluntarily waived $7,518 of certain fees and expenses during the six months ended December 31, 2025.

**12b-1 Distribution Plan**

The Fund has adopted a distribution plan with respect to Class A and Class C shares pursuant to Rule 12b-1 under the 1940 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.

Class I shares do not have a distribution plan.

One Director and certain of the Fund's officers have an interest in Lord Abbett.

&nbsp;&nbsp;&nbsp;&nbsp;**4.** DISTRIBUTIONS AND TAX INFORMATION

Dividends are paid from net investment income, if any. Capital gain distributions are paid from taxable net realized gains from investments transactions, reduced by allowable capital loss carryforwards, if any. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions, which exceed earnings and profits for tax purposes, are reported as a tax return of capital.

The tax character of distributions paid during the six months ended December 31, 2025 was as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Fund** | **Ordinary<br> Income** | **Net<br> Long-Term<br> Capital Gains** | **Total<br> Distributions<br> Paid** |
| US Gov't & GSE Money Market Fund | $28867816 | $– $– &nbsp;&nbsp;&nbsp;&nbsp;$| 28867816 |

---

The tax character of distributions paid during the period ended June 30, 2025 was as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Fund** | **Ordinary<br> Income** | **Net<br> Long-Term<br> Capital Gains** | **Total<br> Distributions<br> Paid** |
| US Gov't & GSE Money Market Fund | $55392786 | $– $– &nbsp;&nbsp;&nbsp;&nbsp;$| 55392786 |

---

**Notes to Financial Statements (unaudited)(continued)**

Net capital losses recognized by the Fund may be carried forward indefinitely and retain their character as short-term and/or long-term losses. Capital losses incurred that will be carried forward are as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Fund** | **Short-Term<br> Losses** | **Long-Term<br> Losses** | **Net Capital<br> Losses** |
| US Gov't & GSE Money Market Fund | $(360394) | $– $| (360394) |

---

&nbsp;&nbsp;&nbsp;&nbsp;**5.** 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 primarily based on the relative 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 in the Statement of Operations and in Directors' fees payable in the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

&nbsp;&nbsp;&nbsp;&nbsp;**6.** LINE OF CREDIT

For the period ended December 31, 2025, the Fund and certain other funds managed by Lord Abbett (collectively, the "Participating Funds") were party to a syndicated line of credit facility with various lenders for $1.675 billion (the "Syndicated Facility") under which 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 the lesser of either one-third or one-fifth of unencumbered fund net assets and $250 million, $300 million, $700 million or $1 billion, in each case based on past borrowings and likelihood of future borrowings, among other factors.

For the period ended December 31, 2025, the Participating Funds were also party to an additional uncommitted line of credit facility with SSB for $330 million (the "Bilateral Facility"). Under the Bilateral Facility, the Participating Funds were subject to graduated borrowing limits of the lesser of either one-third or one-fifth of unencumbered fund net assets and $250 million based on past borrowings and likelihood of future borrowings, among other factors.

These credit facilities are to be used for short-term working capital purposes as additional sources of liquidity to satisfy redemptions.

For the six months ended December 31, 2025, the Fund did not utilize the Syndicated Facility or Bilateral Facility.

&nbsp;&nbsp;&nbsp;&nbsp;**7.** 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.

During the six months ended December 31, 2025, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

**Notes to Financial Statements (unaudited)(continued)**

&nbsp;&nbsp;&nbsp;&nbsp;**8.** 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.

&nbsp;&nbsp;&nbsp;&nbsp;**9.** 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, if any, in 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, 2025, the Fund did not have any securities on loan.

&nbsp;&nbsp;&nbsp;&nbsp;**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 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.

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.

Geopolitical and other events, such as war, acts of terrorism, tariffs and other restrictions on trade, natural disasters, the spread of infectious illnesses, epidemics and pandemics, environmental and other public health issues, supply chain disruptions, inflation, recessions or other events, and

**Notes to Financial Statements (unaudited)(concluded)**

governments' reactions to such events, may lead to increased market volatility and instability in world economies and markets generally and may have adverse effects on the performance of the Fund and its investments.

A widespread health crisis, such as a global pandemic, could cause substantial market volatility, impact the ability to complete redemptions, and adversely impact Fund performance. For example, the effects to public health, business and market conditions resulting from the COVID-19 pandemic have had, and may in the future have, a significant negative impact on the performance of the Fund's investments, including exacerbating other pre-existing political, social and economic risks. In addition, the increasing interconnectedness of markets around the world may result in many markets being affected by events or conditions in a single country or region or events affecting a single or small number of issuers.

It is difficult to accurately predict or foresee when events or conditions affecting the U.S. or global financial markets, economies, and issuers may occur, the effects of such events or conditions, potential escalations or expansions of these events, possible retaliations in response to sanctions or similar actions and the duration or ultimate impact of those events. 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.
