Market Overview

December 31, 2023 (Unaudited)

2023 turned out to be the year of the recession that never was. Despite a regional banking crisis, a debt-ceiling standoff, a new war in the Middle East and some of the highest interest rates in decades, the U.S. economy continued to defy expectations thanks to a strong labor market and a resilient consumer. As the year ended, markets became increasingly optimistic that the Federal Reserve (“Fed”) may indeed be able to achieve the elusive “soft landing.” Expectations that the Fed had reached the end of its tightening cycle resulted in a strong rally in both stock and bond markets during the last two months of the year. The S&P 500^® Index ended 2023 near a record high and, after much volatility throughout the year, the yield on the 10-year Treasury was virtually back to where it started by year-end.

After a slow start to 2023, the U.S. economy picked up steam in the second half, resulting in a solid 2.5% gross domestic product growth rate for the full year. Consumer spending remained the primary driver of economic growth as households were undeterred by higher interest rates and elevated prices. Demand for goods softened during the year but spending on services accelerated. The “experience” economy was in full swing as Americans continued to make up for time lost during the pandemic by splurging on entertainment, food and travel. Business investment also increased as companies aimed to improve efficiency and productivity in the wake of higher labor and materials costs. In addition, funding from the Infrastructure Investment and Jobs Act of 2021 and the CHIPS and Science Act of 2022 spurred construction of new chip and electric vehicle plants during the year. Residential investment remained a drag on growth as higher mortgage rates not only dampened demand but also limited the supply of homes coming to the market as homeowners with existing low-rate mortgages were reluctant to sell. Given the lack of inventory, home prices remained elevated, further limiting housing affordability.

Continued strength in the labor market underpinned the economy’s resiliency in 2023. The U.S. added 2.7 million jobs during the year, which was softer than 2022 but still healthy. The increase in employment was broad-based as demand for workers was steady across most industries. The unemployment rate ended the year at a low 3.7% as available jobs continued to outnumber those seeking employment. Though still high, job openings and quit rates fell during the year in a sign that the labor market is coming into better balance. However, wage growth remained elevated as employers continued to struggle to attract and retain qualified workers.

Despite wage gains, inflation pressures eased in 2023 as supply chains normalized and gas prices fell. Although the improvement is welcome, inflation readings remain elevated – particularly on the services side. Falling goods prices helped offset stubbornly high service prices throughout most of the year; however, disinflation in core goods costs halted in December.

The Fed raised the federal funds rate by a cumulative 100 basis points (1.0%) during 2023, with the last 25 basis-point (0.25%) hike coming at the July Federal Open Market Committee (“FOMC”) meeting. With inflation moving in the right direction, the Fed left the target range for the federal funds rate unchanged at 5.25% to 5.50% for the remaining three meetings of the year. The December meeting tilted decidedly dovish as the Fed acknowledged the progress made on inflation and the expectation that economic growth would begin to moderate. The Fed’s Summary of Economic Projections for the federal funds rate signaled that the Fed’s next move will likely be an ease with the median forecast showing 75 basis points (0.75%) in cuts expected in 2024 and no participants forecasting a hike. Although Fed Chair Jerome H. Powell reiterated that it was too soon to declare victory on inflation, he acknowledged that “we are likely at or near the peak rate for this cycle.”

Markets took the Fed’s nod to an easing bias in December and ran with it. After rising for most of the year, yields fell across the curve after the December meeting as traders in the federal funds futures market began pricing in 150 basis points (1.5%) of cuts in 2024 with easing starting as early as the March FOMC meeting. With the market pricing in twice as many cuts as the Fed, FOMC members cautioned that investors may be expecting rates to come down too far and too fast. Fed Governor Christopher J. Waller warned that while the Fed may ease in 2024, any lowering of interest rates will need to be “carefully calibrated and not rushed.” The December meeting minutes also showed that participants believed there was an “unusually elevated degree of uncertainty” about the policy path and that it was “possible that the economy could evolve in a manner that would make further increases in the target range appropriate.” Despite the Fed’s pushback, markets remain unconvinced and continue to price in aggressive easing in 2024. At some point, the disparity between the Fed’s projected policy path and market expectations will be resolved. Until then, interest rate volatility is likely to be high.

Performance Overview

December 31, 2023 (Unaudited)

The U.S. economy defied expectations of a recession in 2023 and ended up with a 2.5% GDP growth rate for the year. With expectations that the Federal Reserve (“Fed”) had reached the end of its tightening cycle, both the stock and bond markets saw a strong rally during the last two months of the year. The S&P 500 ended up near a record high, and after much volatility throughout the year, the yield on the 10-year Treasury was virtually unchanged from where it started the year. The labor market remained strong during 2023 and inflation continued to drift lower, adding to the thought that the next move by the Fed would be to lower rates.

The Federal Open Market Committee (“FOMC”) raised interest rates a total of 100 basis points (1.0%) during the year, with the last 25 basis point rate increase in July, bringing the fed funds target range to 5.25%-5.50%. The continued tightening cycle during the first half of 2023 was the result of the FOMC continuing to try and get inflation under control. After a pause in the second half of the year and the Fed indicating that their next move is most likely to lower rates, the market is projecting 150 basis points of easing by the end of 2024. However, the last dot plot of the year had the FOMC expecting a fed funds target of 4.50%-4.75% by the end of 2024, only 75 basis points lower than the current target.

During the year, the American Beacon U.S. Government Money Market Select Fund’s primary strategy was to buy fixed rate agencies/treasuries, floating rate agencies along with overnight repurchase agreements. The strategies implemented during the year enabled the Fund to maintain a competitive yield during a rising interest rate environment and outperforming its Lipper benchmark.

For the twelve months ended December 31, 2023, the total return of the American Beacon U.S. Government Money Market Select Fund was 5.00%. The Fund outperformed the Lipper Institutional U.S. Government Money Market Average return of 4.81% by 19 basis points (0.19%). Based on annualized total returns, Lipper Analytical Services ranked the Fund 71^st among 230, 36^th among 196 and 20^th among 139 Institutional U.S. Government Money Market Funds for the one-year, five-year, and ten-year periods ended December 31, 2023, respectively.

* Annualized Yield is a more accurate reflection of the Fund’s current earnings than total return. The seven-day yields refer to the income generated by an investment in the Fund over a seven-day period. This income is then annualized.

   The seven day effective yield is calculated similarly, but the income earned is assumed to have been reinvested. The effective yield will be slightly higher than the current yield because of the compounding effect of this assumed reinvestment.

** Standard & Poor’s (S&P) Rating: The fund is not sponsored, endorsed, sold or promoted by S&P, and S&P makes no representation regarding the advisability of investing in the fund. The credit rating is a forward-looking opinion about a fund’s potential capacity to maintain stable principal or stable net asset value. The rating is an opinion of the date expressed and not a statement of fact or recommendation to purchase, hold or sell any security. Standard & Poor’s rates the creditworthiness of money market funds from AAAm (highest) to Dm (lowest).

Expense Examples

December 31, 2023 (Unaudited)

Fund Expense Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption fees, if applicable, and (2) ongoing costs, including management fees, distribution (12b-1) fees, sub-transfer agent fees, and other Fund expenses. The Examples are intended to help you understand the ongoing cost (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds. The Examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from July 1, 2023 through December 31, 2023.

Actual Expenses

The “Actual” lines of the tables provide information about actual account values and actual expenses. You may use the information on this page, 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 = $8.60), then multiply the result by the “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The “Hypothetical” lines of the tables provide information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the Fund’s actual return). You may compare the ongoing costs of investing in the Funds with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. 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 should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs charged by the Funds, such as sales charges (loads) or redemption fees, as applicable. Similarly, the expense examples for other funds do not reflect any transaction costs charged by those funds, such as sales charges (loads), redemption fees or exchange fees. Therefore, the “Hypothetical” lines of the tables are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If you were subject to any transaction costs during the period, your costs would have been higher.

Notes to Financial Statements

December 31, 2023

1. Organization and Significant Accounting Policies

American Beacon Select Funds (the “Trust”) is organized as a Massachusetts business trust. The Fund, a series within the Trust, is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company. As of December 31, 2023, the Trust consists of two active series, one of which is presented in this filing: American Beacon U.S. Government Money Market Select Fund (the “Fund”). The remaining active series is reported in a separate filing.

American Beacon Advisors, Inc. (the “Manager”) is a Delaware corporation and a wholly-owned subsidiary of Resolute Investment Managers, Inc. (“RIM”) organized in 1986 to provide business management, advisory, administrative, and asset management consulting services to the Trust and other investors. The Manager is registered as an investment advisor under the Investment Advisers Act of 1940, as amended (the “Advisers Act”). The Manager is an indirect wholly-owned subsidiary of Resolute Topco, Inc. (“Topco”), which is owned primarily by various institutional investment funds that are managed by financial institutions and other investment advisory firms. No owner of Topco owns 25% or more of the outstanding equity or voting interests of Topco.

Effective December 29, 2023, the Manager underwent a change of control, which resulted in the termination of the Fund’s previous management agreement. The Board approved a new Management Agreement with the Manager that was effective on December 29, 2023. The new Management Agreement required approval by shareholders of the Fund, and a shareholder meeting was held for the Fund. Please see the sections titled Disclosure Regarding the Approval of New Management Agreement and Results of Shareholder Meeting for more information.

Recently Adopted Accounting Pronouncements

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848); Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform. The guidance is applicable to contracts referencing London Inter-bank Offered Rate (“LIBOR”) or another reference rate that is expected to be discontinued due to reference rate reform. The ASU is effective as of March 12, 2020 and generally can be applied through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 which updates and clarifies ASU No. 2020-04. The amendments in this ASU defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024. Management expects these ASUs will not have a material impact on the Fund’s financial statements.

In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820); Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which provides clarifying guidance that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Management has concluded that the ASU will not have a material impact on the Fund’s financial statements.

Significant Accounting Policies

The following is a summary of significant accounting policies, consistently followed by the Fund in preparation of the financial statements. The Fund is considered an investment company and accordingly, follows the investment company accounting and reporting guidance of the FASB Accounting Standards Codification Topic 946, Financial Services – Investment Companies, a part of Generally Accepted Accounting Principles (“U.S. GAAP”).

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

Security Transactions and Investment Income

Security transactions are recorded as of the trade date for financial reporting purposes. Securities purchased or sold on a when-issued or delayed-delivery basis may be settled beyond a standard settlement period for the security after the trade date.

Interest income for the Fund is earned from settlement date, recorded on the accrual basis, and adjusted, if necessary, for amortization of premiums or accretion of discounts on investment grade short-term securities and zero coupon instruments. For financial and tax reporting purposes, realized gains and losses are determined based on specific lot identification.

Dividends to Shareholders

Dividends from net investment income and net short-term capital gain, if any, are accrued daily and paid monthly. Dividends to shareholders are determined in accordance with federal income tax regulations, which may differ in amount and character from net investment income and realized gains recognized for purposes of U.S. GAAP.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated.

Other

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In the normal course of business, the Trust enters into contracts that provide indemnification to the other party or parties against potential costs or liabilities. The Trust’s maximum exposure under these arrangements is dependent on claims that may be made in the future and, therefore, cannot be estimated. The Trust has had no prior claims or losses pursuant to any such agreement.

2. Transactions with Affiliates

Management Agreement

The Fund and the Manager are parties to a Management Agreement that obligates the Manager to provide investment advisory, fund management, and administrative services to the Fund. As compensation for performing the duties under the Management Agreement, the Manager receives from the Fund an annualized fee of 0.10% of the Fund’s average daily net assets. Management fees paid by the Fund for the year ended December 31, 2023 were $633,255.

Expense Reimbursement Plan

The Manager voluntarily agreed to limit the expense ratio of the Fund in order to maintain a minimum yield for the Fund. During the year ended December 31, 2023, the Manager waived and/or reimbursed expenses as follows:

Fund	Reimbursed Expenses		(Recouped) Expenses			Expiration of Reimbursed Expenses
U.S. Government Money Market Select	$	-	$	(310,250	)*		2026

* This amount represents Recouped Expenses from prior fiscal years and is reflected in Other expenses on the Statement of Operations.

16

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

Of the above amount, $26,350 was disclosed as a Payable for expense recoupment on the Statement of Assets and Liabilities at December 31, 2023.

The Fund has adopted an Expense Reimbursement Plan whereby the Manager may seek repayment of such contractual or voluntary fee reductions and expense reimbursements. Under the policy, the Manager can be reimbursed by the Fund for any contractual or voluntary fee reductions or expense reimbursements if reimbursement to the Manager (a) occurs within three years from the date of the Manager’s waiver/reimbursement and (b) does not cause the Fund’s annual operating expenses to exceed the lesser of the contractual percentage limit in effect at the time of the waiver/reimbursement or time of recoupment. The Fund did not record a liability for potential contingent reimbursement due to the current assessment that reimbursements are uncertain. The carryover of excess expenses potentially reimbursable to the Manager, but not recorded as a liability are as follows:

Fund	Recouped Expenses		Excess Expense Carryover		Expired Expense Carryover		Expiration of Reimbursed Expenses
U.S. Government Money Market Select	$	310,250	$	272,396	$	-		2024
U.S. Government Money Market Select		-		116,469		-		2025

Concentration of Ownership

From time to time, the Fund may have a concentration of one or more accounts constituting a significant percentage of shares outstanding. Investment activities by holders of accounts that represent a significant ownership of more than 5% of the Fund’s outstanding shares could have a material impact on the Fund. As of December 31, 2023, 89% of the Fund’s outstanding shares were held by affiliated American Beacon Funds.

Trustee Fees and Expenses

As compensation for their service to the American Beacon Funds Complex, including the Trust (collectively, the “Trusts”), each Trustee is compensated from the Trusts as follows: (1) an annual retainer of $140,000; (2) meeting attendance fee (for attendance in-person or via teleconference) of (a) $12,000 for in person attendance, or $5,000 for telephonic attendance, by Board members for each regularly scheduled or special Board meeting, (b) $2,500 for attendance by Committee members at meetings of the Audit and Compliance Committee and the Investment Committee, (c) $1,000 for attendance by Committee members at meetings of the Nominating and Governance Committee; and (d) $2,500 for attendance by Board members for each special telephonic Board meeting; and (3) reimbursement of reasonable expenses incurred in attending Board meetings, Committee meetings, and relevant educational seminars. For this purpose, the Trust’s Board of Trustees (the “Board’) considers attendance at regular meetings held by video conference to constitute in-person attendance at a Board meeting. The Trustees also may be compensated for attendance at special Board and/or Committee meetings from time to time. For her service as Board Chair, Ms. Cline receives an additional annual retainer of $50,000. Although she attends several committee meetings at each quarterly Board meeting, she receives a single $2,500 fee each quarter for her attendance at the Audit and Compliance Committee and Investment Committee meetings. The chairpersons of the Audit and Compliance Committee and the Investment Committee each receive an additional annual retainer of $25,000 and the Chair of the Nominating and Governance Committee receives an additional annual retainer of $10,000.

3. Security Valuation and Fair Value Measurements

The Fund values its investments and computes the net asset value (“NAV”) per share at the close of the New York Stock Exchange (the “Exchange”), normally 4:00 p.m. Eastern Time, each day that the Exchange is open for business. In accordance with Rule 2a-7 under the Act, money market securities, with the exception of repurchase agreements, are valued at amortized cost, which approximates fair value; repurchase agreements are valued based on par, which approximates fair value. Securities for which amortized cost is deemed not to reflect fair value are

17

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

stated at fair value as determined in good faith by the Valuation Committee, established by the Board. In the event that a deviation of ¹⁄₂ of 1% or more exists between the $1.00 per share price of the Fund, calculated at amortized cost, and the price per share calculated by reference to market quotations, or if there is any other deviation that the Board believes would result in a material dilution to shareholders or purchasers, the Board will promptly consider the appropriate action that should be initiated.

Rule 2a-5 under the Investment Company Act (the “Valuation Rule”) establishes requirements for determining fair value in good faith for purposes of the Investment Company Act, including related oversight and reporting requirements. The Valuation Rule also defines when market quotations are “readily available,” which is the threshold for determining whether a Fund must fair value a security. Among other things, the Valuation Rule permits the Board to designate the Manager as “valuation designee” to perform the Fund’s fair value determinations subject to board oversight and certain reporting and other requirements intended to ensure that the Board receives the information it needs to oversee the Manager’s fair value determinations. Effective September 8, 2022, the Board has designated the Manager as valuation designee to perform fair value functions in accordance with the requirements of the Valuation Rule. Prior to September 8, 2022, fair value determinations were made pursuant to methodologies approved by the Board.

Investments in open-end mutual funds are valued at the closing NAV per share of the mutual fund on the day of valuation.

Valuation Inputs

Various inputs may be used to determine the fair value of the Fund’s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1	-	Quoted prices in active markets for identical securities.
Level 2	-	Prices determined using other significant observable inputs. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and others.
Level 3	-	Prices determined using other significant unobservable inputs. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in pricing an investment.

Level 1 and Level 2 trading assets and trading liabilities, at fair value

Money market securities are valued using amortized cost, in accordance with rules under the Act. Generally, amortized cost approximates the current value of a security, but since the value is not obtained from a quoted price in an active market, such securities are reflected as Level 2.

With respect to the Fund’s investments that do not have readily available market quotations, the Board has designated the Adviser as its valuation designee to perform fair valuations pursuant to Rule 2a-5 under the Act (the “Valuation Designee”). If market prices are not readily available or are deemed unreliable, the Valuation Designee will use the fair value of the security or other instrument as determined in good faith under policies and procedures established by and under the supervision of the Board (“Valuation Procedures”). Market prices are considered not readily available where there is an absence of current or reliable market-based data (e.g., trade information or broker quotes), including where events occur after the close of the relevant market, but prior to the NYSE Close, that materially affect the values of the Fund’s portfolio holdings or assets. In addition, market prices are considered not readily available when, due to extraordinary circumstances, the exchanges or markets on which the securities or other instruments trade do not open for trading for the entire day and no other market prices are available. Fair value pricing is subjective in nature and the use of fair value pricing by the Valuation Designee may cause the NAV of the Fund’s shares to differ significantly from the NAV that would have been calculated using market prices at the close of the exchange on which a portfolio holding is primarily traded. There can be no assurance that the Fund could obtain the fair value assigned to an investment if the Fund were to sell the investment at approximately the time at which the Fund determines its NAV.

18

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

Investments in registered open-end investment management companies will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy.

4. Securities and Other Investments

Other Government Money Market Fund Securities

The Fund, at times, may invest in shares of other government money market funds. Investments in the securities of other government money market funds may involve duplication of advisory fees and certain other expenses. By investing in another government money market fund, the Fund becomes a shareholder of that government money market fund. As a result, Fund shareholders indirectly will bear the Fund’s proportionate share of the fees and expenses paid by shareholders of the other government money market fund, in addition to the fees and expenses Fund shareholders directly bear in connection with the Fund’s own operations. These other fees and expenses are reflected as Acquired Fund Fees and Expenses and are included in the Fees and Expenses Table for the Fund in its Prospectus, if applicable. Investment in other government money market funds may involve the payment of substantial premiums above the value of such issuer’s portfolio securities.

Although a money market fund is designed to be a relatively low risk investment, it is not free of risk. Despite the short maturities and high credit quality of a money market fund’s investments, increases in interest rates and deteriorations in the credit quality of the instruments the money market fund has purchased may reduce the money market fund’s yield and can cause the price of a money market security to decrease. In addition, a money market fund is subject to the risk that the value of an investment may be eroded over time by inflation.

Repurchase Agreements

A repurchase agreement is an agreement between the Fund as purchaser and an approved counterparty as seller. The agreement is backed by collateral in the form of securities and/or cash transferred by the seller to the buyer, sometimes to be held by an eligible third-party custodian. Under the agreement, the Fund acquires securities from the seller and the seller simultaneously commits to repurchase the securities at an agreed upon price and date, normally within a week or on demand. The price for the seller to repurchase the securities is greater than the Fund’s purchase price, reflecting an agreed upon rate that is the equivalent of interest. During the term of the repurchase agreement, the Fund monitors on a daily basis the market value of the collateral subject to the agreement and, if the market value of the securities falls below the seller’s repurchase amount provided under the repurchase agreement, the seller is required to transfer additional securities or cash collateral equal to the amount by which the market value of the securities falls below the repurchase amount. Because a repurchase agreement permits the Fund to invest temporarily available cash on a fully-collateralized basis, repurchase agreements permit the Fund to earn income while retaining flexibility in pursuit of longer-term investments. Repurchase agreements may exhibit the economic characteristics of loans by the Fund.

The obligation of the seller under the repurchase agreement is not guaranteed, and there is a risk that the seller may fail to repurchase the underlying securities, whether because of the seller’s bankruptcy or otherwise. In such event, the Fund would attempt to exercise its rights with respect to the underlying collateral, including possible sale of the securities. The Fund may incur various expenses in connection with the exercise of its rights and may be subject to various delays and risks of loss, including (a) possible declines in the value of the underlying collateral, (b) possible reduction in levels of income and (c) lack of access to the securities (if they are held through a third-party custodian) and possible inability to enforce the Fund’s rights. The Board has established procedures pursuant to which the Manager monitors the creditworthiness of the counterparties with which the Fund enters into repurchase agreement transactions.

The Fund may enter into repurchase agreements with member banks of the Federal Reserve System or registered broker-dealers who, in the opinion of the Manager, present a minimal risk of default during the term of the agreement. The underlying securities which serve as collateral for repurchase agreements may include fixed

income and equity securities such as U.S. Government and agency securities, municipal obligations, corporate obligations, asset-backed securities, mortgage-backed securities, common and preferred stock, depositary receipts, ETFs, corporate obligations and convertible securities.

Repurchase agreements that are collateralized fully may be deemed to be an acquisition of the underlying collateral (i.e. cash and/or Government Securities) and thus allow the Fund to have exposure to the seller that exceeds the typical issuer limit under Rule 2a-7.

As of December 31, 2023, the Fund had investments in repurchase agreements with a gross value of $225,000,000 as disclosed in the Schedule of Investments and the Statement of Assets and Liabilities.

U.S. Government Agency Securities

U.S. Government agency securities are issued or guaranteed by the U.S. Government or its agencies or instrumentalities. Some obligations issued by U.S. Government agencies and instrumentalities are supported by the full faith and credit of the U.S. Treasury; others by the right of the issuer to borrow from the U.S. Treasury; others by discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; and others only by the credit of the agency or instrumentality. U.S. Government securities bear fixed, floating or variable rates of interest. While the U.S. Government currently provides financial support to certain U.S. Government-sponsored agencies or instrumentalities, no assurance can be given that it will always do so, since it is not so obligated by law. U.S. Government securities include U.S. Treasury bills, notes and bonds, Federal Home Loan Bank (“FHLB”) obligations, Federal Farm Credit Bank (“FFCB”) obligations, U.S. Government agency obligations and repurchase agreements secured thereby. U.S. Government agency securities are subject to credit risk and interest rate risk.

U.S. Treasury Obligations

U.S. Treasury obligations include bills (initial maturities of one year or less), notes (initial maturities between two and ten years), and bonds (initial maturities over ten years) issued by the U.S. Treasury, Separately Traded Registered Interest and Principal component parts of such obligations (known as “STRIPS”) and inflation-indexed securities. The prices of these securities (like all debt securities) change between issuance and maturity in response to fluctuating market interest rates and credit ratings. The principal and interest components of selected securities are traded independently under the STRIPS program. Under the STRIPS program, the principal and interest components are individually numbered and separately issued by the U.S. Treasury at the request of depository financial institutions, which then trade the component parts independently.

Variable or Floating Rate Obligations

The interest rates payable on certain fixed-income securities in which the Fund may invest are not fixed and may fluctuate based upon changes in market rates. A variable rate obligation has an interest rate which is adjusted at predesignated periods in response to changes in the market rate of interest on which the interest rate is based. Variable and floating rate obligations are less effective than fixed rate instruments at locking in a particular yield. Nevertheless, such obligations may fluctuate in value in response to interest rate changes if there is a delay between changes in market interest rates and the interest reset date for the obligation, or for other reasons.

The terms of the variable or floating rate demand instruments that the Fund may purchase provide that interest rates are adjustable at intervals ranging from daily up to 397 calendar days, and the adjustments are based upon current market levels, the prime rate of a bank or other appropriate interest rate adjustment index as provided in the respective instruments. Some of these instruments are payable on demand on a daily basis or on not more than seven days’ notice. Others, such as instruments with quarterly or semi-annual interest rate adjustments, may be put back to the issuer on designated days, usually on not more than thirty days’ notice. Still others are automatically called by the issuer unless the Fund instructs otherwise.

Notes to Financial Statements

December 31, 2023

The Fund may consider the maturity of a long-term variable or floating rate demand instrument to be shorter than its ultimate stated maturity under specified conditions. The acquisition of variable or floating rate demand notes for the Fund must also meet the requirements of rules issued by the U.S. Securities and Exchange Commission (“SEC”) applicable to the use of the amortized cost method of securities valuation, specifically Rule 2a-7 under the Act. The Fund will also consider the liquidity of the market for variable and floating rate instruments, and in the event that such instruments are illiquid, the Fund’s investments in such instruments will be subject to the limitation on illiquid investments.

Pursuant to Rule 2a-7 under the Act, variable or floating rate obligations may be deemed to have maturities shorter than their stated maturities as follows:

(1) An obligation that is issued or guaranteed by the U.S. Government or any agency thereof which has a variable rate of interest readjusted no less frequently than every 397 days will be deemed by the Fund to have a maturity equal to the period remaining until the next readjustment of the interest rate. A U.S. Government security that is a floating rate security shall be deemed to have a remaining maturity of one day.

(2) A variable rate obligation, the principal amount of which must unconditionally be paid in 397 days or less, will be deemed by the Fund to have a maturity equal to the earlier of the period remaining until the next readjustment of the interest rate or the period remaining until the principal amount can be recovered through demand.

(3) A floating rate obligation, the principal amount of which must unconditionally be paid in 397 days or less, will be deemed by the Fund to have a maturity of one day, except for purposes of determining the Fund’s weighted average life, in which case it shall be deemed to have a maturity equal to the period remaining until the principal amount can be recovered through demand.

(4) A variable rate obligation that is subject to a demand feature will be deemed by the Fund to have a maturity equal to the longer of the period remaining until the next readjustment of the interest rate or the period remaining until the principal amount can be recovered through demand.

(5) A floating rate obligation that is subject to a demand feature will be deemed by the Fund to have a maturity equal to the period remaining until the principal amount can be recovered through demand. As used above, an obligation is “subject to a demand feature” when the Fund is entitled to receive the approximate amortized cost of the security plus accrued interest, if any, at the later of the time of exercise or the settlement of the transaction, paid within 397 calendar days of exercise.

5. Principal Risks

Investing in the Fund may involve certain risks including, but not limited to, those described below.

Credit Risk

The value of a security held by the Fund may decline if the security’s credit quality, or that of the security’s issuer or provider of credit support is downgraded or their credit quality otherwise falls. A decline in the credit rating of an individual security held by the Fund may have an adverse impact on its price and make it difficult for the Fund to sell it. Ratings represent a rating agency’s opinion regarding the quality of the security and are not a guarantee of quality. Rating agencies might not always change their credit rating on an issuer or security in a timely manner to reflect events that could affect the issuer’s ability to make timely payments on its obligations. As with any money market fund, there is the risk that the issuers or guarantors of securities owned by the Fund, including securities issued by U.S. Government agencies, which are not backed by the full faith and credit of the U.S. Government, will default on the payment of principal or interest or the obligation to repurchase securities from the Fund. This could cause the Fund’s NAV to decline below $1.00 per share.

21

Notes to Financial Statements

December 31, 2023

Interest Rate Risk

There is a risk that a decline in short-term interest rates would lower the Fund’s yield and the return on your investment, which may have an adverse effect on the Fund’s ability to provide a positive yield to its shareholders. Changes in interest rates also may change the resale value of the instruments held in the Fund’s portfolio. Generally, the value of investments with interest rate risk will move in the opposite direction to movements in interest rates. When interest rates go up, the market values of previously issued money market instruments generally decline and may have an adverse effect on the Fund’s ability to maintain a stable $1.00 share price. As of the date of this report, interest rates are historically low. In the future, interest rates may rise, perhaps significantly and/or rapidly, potentially resulting in substantial losses to the Fund.

Liquidity Risk

The Fund is susceptible to the risk that certain investments held by the Fund may become less liquid in response to market developments or adverse credit events that may affect issuers or guarantors of a security. An inability to sell a portfolio position at favorable times or prices can adversely affect the Fund’s ability to maintain a $1.00 share price. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. In addition, the Fund may experience difficulty satisfying redemption requests within the time periods stated in the “Redemption Policies” section of this Prospectus because of unusual market conditions, an unusually high volume of redemption requests or other reasons.

Market Risk

In recent periods, fixed income instruments have experienced unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. These events have reduced the willingness and ability of some lenders to extend credit, and have made it more difficult for some borrowers to obtain financing on attractive terms, if at all. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. A rise in protectionist trade policies, risks associated with the United Kingdom’s vote to leave the European Union, the risk of a “trade war” between the United States and China, and the possibility of changes to some international trade agreements, could affect the economies of many nations, including the United States, in ways that cannot necessarily be foreseen at the present time. The severity or duration of adverse economic conditions may also be affected by policy changes made. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasigovernmental organizations. In addition, political and governmental events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. Because the impact on the markets has been widespread, it may be difficult to identify both risks and opportunities using past models of the interplay of market forces, or to predict the duration of these market conditions. Interest rates have been unusually low in recent years in the U.S. and abroad. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase, whether brought about by U.S. policy makers or by dislocations in world markets. In addition, there is a risk that the prices of goods and services in the U.S. and many foreign economies may decline over time, known as deflation (the opposite of inflation). Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely.

Mortgage-Related Securities Risk

Mortgage-related and asset-backed securities are subject to market risks for fixed-income securities, which include, but are not limited to: credit risk, interest rate risk, prepayment risk and extension risk. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of difficult or frozen credit markets, significant changes in interest rates, or

22

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

deteriorating economic conditions, mortgage-related securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Additionally, during such periods and also under normal conditions, these securities are also subject to prepayment and call risk. Gains and losses associated with prepayments will increase/decrease the income available for distributions by the Fund and the Fund’s yield. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Some of these securities may receive little or no collateral protection from the underlying assets and are thus subject to the risk of default. Moreover, declines in the credit quality of the issuers of mortgage-related securities or instability in the markets for such securities may affect the value and liquidity of such securities, which could result in losses to the Fund. Additionally, certain mortgage-related securities may include securities backed by pools of loans made to “subprime” borrowers or borrowers with blemished credit histories; the risk of defaults is generally higher in the case of mortgage pools that include such subprime mortgages.

Net Asset Value Risk

There is no assurance that the Fund will meet its investment objective of maintaining a stable price of $1.00 per share on a continuous basis. Furthermore, there can be no assurance that the Fund’s affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share.

Other Investment Companies Risk

The Fund may invest in shares of other government money market funds. To the extent that the Fund invest in shares of other government money market funds, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund’s direct fees and expenses and will be subject to the risks associated with investments in those Funds.

Recent Market Events Risk

Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, the risks discussed herein associated with an investment in the Fund may be increased.

Although interest rates were unusually low in recent years in the U.S. and abroad, in 2022, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates may continue to increase, the timing, frequency or magnitude of any such increases, or when such increases might stop. Additionally, various economic and political factors could cause the Federal Reserve or another foreign central bank to change their approach in the future and such actions may result in an economic slowdown in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility, reduce liquidity across various markets or decrease confidence in the markets. Additionally, high public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

In March 2023, the shutdown of certain financial institutions in the U.S. and questions regarding the viability of other financial institutions raised economic concerns over disruption in the U.S. and global banking systems. There can be no certainty that the actions taken by the U.S. or foreign governments will be effective in mitigating

23

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

the effects of financial institution failures on the economy and restoring public confidence in the U.S. and global banking systems.

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth; risks associated with a trade agreement between the United Kingdom and the European Union; the risks associated with ongoing trade negotiations with China; and the possibility of changes to some international trade agreements; political or economic dysfunction within some nations, including major producers of oil; and dramatic changes in commodity and currency prices could have adverse effects that cannot be foreseen at the present time.

Tensions, war, or open conflict between nations, such as between Russia and Ukraine, in the Middle East or in eastern Asia could affect the economies of many nations, including the United States. The duration of ongoing hostilities in the Middle East and between Russia and Ukraine, and any sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

Regulators in the U.S. have proposed and recently adopted a number of changes to regulations involving the markets and issuers, some of which apply to the Fund. The full effect of various newly-adopted regulations is not currently known. Additionally, it is not clear whether the proposed regulations will be adopted. However, due to the broad scope of the new and proposed regulations, certain changes could limit the Fund’s ability to pursue its investment strategies or make certain investments, or may make it more costly for the Fund to operate, which may impact performance.

Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.

Redemption Risk

The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices.

Repurchase Agreement Risk

The obligations of a counterparty to a repurchase agreement are not guaranteed. The Fund permits various forms of securities as collateral whose values fluctuate and are issued or guaranteed by the U.S. Government. There are risks that a counterparty may default at a time when the collateral has declined in value, or a counterparty may become insolvent, which may affect the Fund’s right to control the collateral. Repurchase agreements are subject to credit risk.

U.S. Government Securities and Government-Sponsored Enterprises Risk

A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity. The market prices for such securities are not guaranteed and will fluctuate. Securities held by the Fund that are issued by government-sponsored enterprises, such as the Federal National Mortgage Association (‘‘Fannie Mae’’), Federal Home Loan Mortgage Corporation (‘‘Freddie Mac’’), FHLB, and the FFCB, are not guaranteed by the U.S. Treasury and are not backed by the full faith and credit of the U.S. government, and no assurance can be given that the U.S. government will provide financial support if these organizations do not have the funds to meet future payment obligations. U.S.

24

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

government securities and securities of government-sponsored entities are also subject to credit risk, interest rate risk and market risk. The rising U.S. national debt may lead to adverse impacts on the value of U.S. government securities due to potentially higher costs for the U.S. government to obtain new financing.

Variable and Floating Rate Securities Risk

The coupons on variable and floating-rate securities are not fixed and may fluctuate based upon changes in market rates. A variable rate security has a coupon that is adjusted at pre-designated periods in response to changes in the market rate of interest on which the interest rate is based. The coupon on a floating rate security is generally based on an interest rate, such as a money-market index, Secured Overnight Financing Rate (“SOFR”), LIBOR or a Treasury bill rate. Variable and floating rate securities are subject to interest rate risk and credit risk. As short-term interest rates decline, the coupons on variable and floating-rate securities typically decrease. Alternatively, during periods of rising short-term interest rates, the coupons on variable and floating-rate securities typically increase. Changes in the coupons of variable and floating-rate securities may lag behind changes in market rates or may have limits on the maximum increases in the coupon rates. The value of variable and floating-rate securities may decline if their coupons do not rise as much, or as quickly, as interest rates in general. Conversely, variable and floating rate securities will not generally increase in value if interest rates decline. Certain types of variable and floating rate instruments may be subject to greater liquidity risk than other debt securities.

Yield and Securities Selection Risk

The yield paid by the Fund will vary and may be affected by the Manager’s decisions regarding the Fund’s dollar-weighted average maturity (“WAM”) and dollar-weighted average life (“WAL”). If the Manager sets the Fund’s maturity target in a manner that does not correlate with the movement of interest rate trends it could have an adverse effect on the Fund’s yield. Income from the Fund may be at rates less than inflation.

Offsetting Assets and Liabilities

The Fund is party to Master Repurchase Agreements (“Master Repo Agreements”) that govern transactions between the Fund and selected counterparties. The Master Repo Agreements contain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for Repurchase Agreements. The Fund has elected not to offset qualifying financial instruments on the Statement of Assets and Liabilities, as such financial instruments are presented on a gross basis. The impacts of netting arrangements that provide the right to offset are detailed below, if applicable. The net amount represents the net receivable or payable that would be due from or to the counterparty in the event of default. Exposure from borrowings and other financing agreements such as repurchase agreements can only be netted across transactions governed by the same Master Repo Agreement with the same legal entity. All amounts reported below represent the balance as of the report date, December 31, 2023.

						Gross Amounts Not Offset in the Statement of Assets and Liabilities

6. Federal Income and Excise Taxes

It is the policy of the Fund to qualify as a regulated investment company (“RIC”), by complying with all applicable provisions of Subchapter M of the Internal Revenue Code, as amended, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes. For federal income tax purposes, the Fund is treated as a single entity for the purpose of determining such qualification.

The Fund does not have any unrecorded tax liabilities in the accompanying financial statements. Each of the tax years in the four year period ended December 31, 2023 remain subject to examination by the Internal Revenue Service. If applicable, the Fund recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in “Other expenses” on the Statement of Operations.

Dividends are categorized in accordance with income tax regulations which may treat certain transactions differently than U.S. GAAP. Accordingly, the character of distributions and composition of net assets for tax purposes may differ from those reflected in the accompanying financial statements.

The tax character of distributions paid were as follows:

	Year Ended December 31, 2023		Year Ended December 31, 2022
Distributions paid from:
Ordinary income*	$	30,914,324	$	9,298,144
Long-term capital gains		1,327		-
Total distributions paid	$	30,915,651	$	9,298,144

^* For tax purposes, short-term gains are considered ordinary income distributions.

As of December 31, 2023, the components of distributable earnings (deficits) on a tax basis were as follows:

Fund	Tax Cost		Unrealized Appreciation		Unrealized (Depreciation)		Net Unrealized Appreciation (Depreciation)
U.S. Government Money Market Select	$	755,761,044	$	-	$	-	$	-

Fund	Net Unrealized Appreciation (Depreciation)		Undistributed Ordinary Income		Undistributed Long-Term Capital Gains		Accumulated Capital and Other (Losses)		Other Temporary Differences			Distributable Earnings
U.S. Government Money Market Select	$	-	$	-	$	-	$	-	$	(214	)	$	(214	)

Financial reporting records are adjusted for permanent book/tax differences to reflect tax character. Financial records are not adjusted for temporary differences. The temporary differences between financial reporting and tax-basis reporting of unrealized appreciation (depreciation) are attributable primarily to dividends payable.

Due to inherent differences in the recognition of income, expenses, and realized gains (losses) under U.S. GAAP and federal income tax regulations, permanent differences between book and tax reporting have been identified and appropriately reclassified on the Statement of Assets and Liabilities.

Accordingly, the following amounts represent current year permanent differences derived from distributions in excess of current earnings as of December 31, 2023:

Fund	Paid-In-Capital			Distributable Earnings/(Deficits)
U.S. Government Money Market Select	$	(2,088	)	$	2,088

American Beacon U.S. Government Money Market Select Fund^SM

Notes to Financial Statements

December 31, 2023

For federal income tax purposes, the Fund measures its capital loss carryforwards annually at December 31, its fiscal year end. Capital loss carryforwards retain their character as short-term and/or long-term and may be carried forward and applied against future realized capital gains with no expiration date.

As of December 31, 2023, the Fund did not have any capital loss carryforwards.

7. Borrowing Arrangements

Effective November 10, 2023 (the “Effective Date”), the Fund, along with certain other funds managed by the Manager (“Participating Funds”), renewed a committed revolving line of credit (the “Committed Line”) agreement with State Street Bank and Trust Company (the “Bank”) to be used to facilitate portfolio liquidity. The maximum borrowing amount under the Committed Line is $100 million with interest at a rate equal to the higher of (a) Overnight Bank Funding Rate (“OBFR”) daily fluctuating rate per annum equal to 1.25% plus the sum of 0.10% or (b) the Federal Funds daily fluctuating rate per annum on amounts borrowed. Each of the Participating Funds paid a proportional amount of a quarterly commitment fee at a rate of 0.25% per annum on the unused portion of the Committed Line amount. The Committed Line expires November 8, 2024, unless extended by the Bank or terminated by the Participating Funds in accordance with the agreement. Prior to the Effective Date, the maximum borrowing amount under the Committed Line was $100 million with an expiration date November 9, 2023.

On the Effective Date, the Fund, along with certain other Participating Funds managed by the Manager, also renewed an uncommitted discretionary demand revolving line of credit (the “Uncommitted Line”) agreement with the Bank to be used to facilitate portfolio liquidity. The maximum borrowing amount under the Uncommitted Line is $100 million with interest at a rate equal to the higher of (a) OBFR daily fluctuating rate per annum equal to 1.25% plus the sum of 0.10% or (b) the Federal Funds daily fluctuating rate per annum on amounts borrowed on each outstanding loan. Each of the Participating Funds paid a proportional amount of a closing fee of $35,000 on the Effective Date. The Uncommitted Line expires November 8, 2024, unless extended by the Bank or terminated by the Participating Funds in accordance with the agreement. Prior to the Effective Date, the maximum borrowing amount under the Uncommitted Line was $100 million with an expiration date November 9, 2023.

The Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Loan expense” on the Statement of Operations, along with commitment fees, that have been allocated among the Participating Funds based on average daily net assets.

During the year ended December 31, 2023, the Fund did not utilize these facilities.

Disclosure Regarding the Approval of New Management Agreement (Unaudited)

On December 29, 2023, Resolute Investment Managers, Inc. (“RIM”), the parent company of American Beacon Advisors, Inc. (“Manager”), and certain of its affiliates (collectively, “Resolute”), and their equity owners completed a transaction (“Transaction”) with certain creditors of RIM to strengthen Resolute’s capital structure (the “Closing”). In connection with the Closing, (i) Resolute Investment Holdings, LLC (“RIH”), Resolute Topco, Inc. (“Topco”), which was a wholly-owned subsidiary of RIH prior to the Closing, RIM, and certain of their affiliates, and (ii) the prior owners of approximately 93% of RIH, entered into an exchange agreement with certain creditors of RIM (the “New Ownership Group”) pursuant to which, among other things, new equity interests in Topco were issued to members of the New Ownership Group and the then-existing equity interests in RIH were retired and canceled.

Upon the Closing, the Manager became wholly owned indirectly by the New Ownership Group. This change in control was deemed to be an “assignment” under the Investment Company Act of 1940 Act, as amended (“1940 Act”), of the existing management agreement (“Prior Management Agreement”) between the Manager and American Beacon Select Funds (“Trust”) with respect to the American Beacon U.S. Government Money Market Select Fund (“Fund”). As required by the 1940 Act, the Prior Management Agreement provided for its automatic termination in the event of an assignment, and, therefore, terminated upon the Closing.

The Board of Trustees (“Trustees” or “Board”) of the Trust met by videoconference on July 7, 2023, and in-person on July 12, 2023 (“July Meetings”), to discuss the Transaction and consider the effect that the Transaction would have on the Fund. In addition, the Board received various information from the Manager regarding the intended purposes and framework of the Transaction at its meetings in-person on February 28–March 1, 2023 (“March Meeting”) and June 6–7, 2023, and by videoconference on May 16, 2023 (“May-June Meetings”). Following the March Meeting, the Board designated an ad hoc special committee (“Committee”) to meet with representatives of the Manager and receive updates on the negotiations and, as appropriate, to provide input with respect to the process. Throughout this process, the Board and the Committee were advised by independent legal counsel and received guidance concerning, among other matters, the Trustees’ responsibilities in connection with their consideration with respect to the Fund of a new Management Agreement (“New Management Agreement”). The Trustees were advised that the New Management Agreement would replace the Prior Management Agreement upon the assignment and termination of the Prior Management Agreement upon the Closing.

In advance of the July Meetings, the Board requested and received detailed information from the Manager regarding the Transaction. In connection with the Transaction, the Board reviewed materials furnished by the Manager, which had been reviewed, as applicable, by representatives of the New Ownership Group, and met with senior representatives of the Manager. The Board also reviewed the material terms of the Transaction and considered its possible effects on the Fund and its shareholders. During these meetings, representatives of the Manager indicated their belief that the Transaction would not adversely affect the continued operation of the Fund or the capabilities of the key personnel of the Manager who currently manage the Fund to continue to provide services to the Fund at the current levels.

In evaluating the New Management Agreement, the Trustees considered that they generally have been satisfied with the nature and quality of the services provided to the Fund by the Manager, including investment advisory and administrative services, and that the Fund would be best served by an arrangement that appeared likely to maintain the continuity and stability of these services. Accordingly, the Board considered information communicated by the Manager regarding the anticipated benefits of the substantially strengthened capital structure of Resolute that would result from the Transaction, and the related positive anticipated impact on the Manager’s resources available for future staffing, compensation, and staff retention. The Manager’s representatives also indicated that they believe that the Transaction best facilitates continuity of management and view such continuity as beneficial to the long-term success of the Fund, but noted that there could be no assurance of any particular benefits that may result.

In connection with the Board’s determination to approve the New Management Agreement, the Trustees considered, among other information, the following factors as they relate to the Transaction:

• The manner in which the Fund’s assets are managed will not change as a result of the Transaction, and the same people who currently manage the Fund’s assets are expected to continue to do so after the Transaction;

Disclosure Regarding the Approval of New Management Agreement (Unaudited)

• The fee rates payable by the Fund under the New Management Agreement are the same as the fee rates payable under the Prior Management Agreement;

• The New Management Agreement is identical in all material respects to the Prior Management Agreement;

• The Manager would provide the same services to the Fund pursuant to the New Management Agreement as it had been providing under the Prior Management Agreement;

• The Manager’s personnel who will provide management services to the Fund are not expected to change and the commitment of the New Ownership Group to retain key personnel currently employed by the Manager who currently provide services to the Fund;

• Resolute’s substantially strengthened capital structure following the Closing, which the Manager represented would enable Resolute to continue to provide the Manager with the financial resources necessary to continue to operate and grow the Fund;

• The anticipated governance structure to be employed in the management of RIM and that following the Transaction the Manager is expected to maintain continuity of management, a similar degree of operational autonomy and its current culture of compliance;

• The various measures in place and/or prepared to be employed to address any potential impact of the Transaction on the Manager’s business, including its day-to-day operations;

• The anticipated absence of any adverse impact of the Transaction on the Fund’s key service providers;

• The alignment of the strategic business objectives of the New Ownership Group with regard to its investment in the Manager and the Manager’s activities with respect to the Trust, which objectives are consistent with the Manager’s current objectives;

• Fund shareholders will not bear any costs in connection with the Transaction, inasmuch as the Manager and, indirectly, the New Ownership Group will bear the costs, fees and expenses incurred by the Fund in connection with the Transaction, including the proxy statement, the fees and expenses of accountants and attorneys relating to the Transaction, and the fees and expenses of the Board and the Committee for meetings held in connection with the Transaction;

• The Fund may realize benefits as a result of the Transaction, including that the Transaction is expected to maintain continuity of management of the Fund and may reduce the potential vulnerability to a future change in control of the Manager that could be adverse to the Fund’s interests and affect the retention of key employees providing services to the Fund;

• The Manager’s representation that there had been no material changes or developments relating to the Manager since the May-June Meetings, other than the changes or developments subsequently reported to the Board; and

• The Trustees had requested and evaluated information relevant to the renewal of the Prior Management Agreement at their May-June Meetings.

In light of the proximity of the Board’s consideration of the renewal of the Prior Management Agreement at the May-June Meetings, the Trustees determined that it was not necessary to repeat certain aspects of the review conducted in connection with the approvals made the prior month. Based on the process undertaken and the considerations weighed by the Board with respect to the renewal of the Prior Management Agreement, and the Board’s due diligence review in connection with the Transaction during the July Meetings, the Board approved the New Management Agreement at the July 12, 2023 meeting, and recommended that the Fund shareholders also approve the New Management Agreement. The factors considered by the Board in connection with the approval of the Prior Management Agreement are described in the section of the Fund’s Semi-Annual Report dated June 30, 2023 titled “Disclosure Regarding Approvals of the Management and Investment Advisory Agreement.”
