Annual Shareholder Report

as of December 31, 2025

U.S. Monthly Income Fund for Puerto Rico Residents, Inc. Class A - PRAJX

This annual shareholder report contains important information about U.S. Monthly Income Fund for Puerto Rico Residents, Inc. (the "Fund") for the period from January 1, 2025, to December 31, 2025. You can find additional information about the Fund at www.ubs.com/prfunds or by contacting us at

What were the Fund costs for last year?	Class Name	Cost of a $10,000 investment	Cost paid as a percentage of a $10,000 investment
Annual Fund Operating Expenses	Class A	$200	1.92%
(based on a hypothetical $10,000 investment)

How did the Fund perform last year and what affected its performance?

The U.S. municipal portion of the portfolio returned 7.35% in 2025. The breakdown of the return was 5.31% yield return and a 2.04% market return as interest rates declined across the yield curve. The market yield of the portfolio increased 0.26% during the year. The yield curve steepened 0.37% during the year. The yield of the

two-year

note decreased 0.77% in response to cuts in the federal funds rate during the last quarter of the year. The yield of the

ten-year

note decreased 0.40% as it was more focused on inflation, which remained somewhat elevated and above the 2% target of the Federal Reserve.

The biggest detractor to performance was the lack of housing bonds in the portfolio. Housing was the best performing sector during the year. An underweight to state and local bonds also hurt performance. An increase in the exposure to bonds of 10 to 12 years was the primary contributor to performance. The use of futures had a neutral impact on full year performance. The Fund held no futures contracts in the portfolio at

year-end.

The Puerto Rico portion of the portfolio consists of one 6.75% coupon Autopistas Metropolitanas ("Metropistas") bond and several mortgage-backed securities residential mortgage pools issued and guaranteed by the Federal National Mortgage Association (FNMA) ("MBS"). Both had positive returns. Metropistas had a total return of 8.45%. The MBS consist of pools with coupons ranging from 3.00% to 5.50%. The largest pool, with a coupon of 3.5% representing approximately 43% of the MBS, had a total return of 9.2%.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

1.	Reporting Entity and Significant Accounting Policies

U.S. Monthly Income Fund for Puerto Rico Residents, Inc. (the "Fund") is a diversified, open-endmanagement investment company. The Fund is a corporation organized under the laws of the Commonwealth of Puerto Rico and is registered as an investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), as of May 14, 2021. Prior to such date and since inception, the Fund was registered and operated under the Puerto Rico Investment Companies Act of 1954, as amended. The Fund's offerings of securities are registered under the Securities Act of 1933, as amended. The Fund was incorporated on September 27, 2012, and commenced operations on January 18, 2013.

The Fund is divided into a Puerto Rico taxable securities portion and a U.S. portion consisting primarily of United States municipal securities. UBS Asset Managers of Puerto Rico, a division of UBS Trust Company of Puerto Rico ("UBSTC"), is the Fund's Investment Adviser (the "Investment Adviser") and directly manages the Puerto Rico taxable securities portion. Nuveen Asset Management, LLC is the sub-investmentadviser (the "Sub-Adviser")managing the U.S. portion. UBSTC is also the Fund's Administrator (the "Administrator") and the Transfer Agent (the "Transfer Agent").

The Fund's investment objective is to provide current income, consistent with the preservation of capital. There is no assurance that the Fund will achieve its investment objective.

Certain charter provisions of the Fund might be void and unenforceable under the 1940 Act including, without limitation, provisions (i) permitting indemnification of officers and directors to the fullest extent permitted by Puerto Rico law, (ii) setting forth the required vote for changes to fundamental policies of the Fund, and (iii) stating that, to the fullest extent permitted by Puerto Rico law, no officer or director will be liable to the Fund or shareholders.

The following is a summary of the Fund's significant accounting policies:

Use of Estimates in Financial Statements Preparation

The Fund is an investment company that applies the accounting and reporting guidance applicable to investment companies in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946, Financial Services-Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Net Asset Value Per Share

The net asset value ("NAV") per share of the Fund is determined daily by the Administrator after the close of trading on the New York Stock Exchange (NYSE), or if such day is not a business day in New York or Puerto Rico, on the next succeeding business day. The NAV per share is computed by dividing the total assets of the Fund, less its liabilities, by the total number of shares outstanding.

Valuation of Investments

The Fund's assets are valued by UBSTC on the basis of valuations provided by pricing services or by dealers which were approved by Fund management and the Board of Directors (the "Board"). In arriving at their valuation, pricing sources may use both a grid matrix of securities values as well as the evaluations of their staff. The valuation, in either case, could be based on information concerning actual market transactions and quotations from dealers or a grid matrix performed by an outside vendor that reviews certain market and security factors to arrive at a bid price for a specific security.

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

Certain Puerto Rico obligations have a limited number of market participants and, thus, might not have a readily ascertainable market value and may have periods of illiquidity. If the Fund has securities for which quotations are not readily available from any source, they will be fair valued by or under the direction of the Investment Adviser utilizing quotations and other information concerning similar securities obtained from recognized dealers. The Investment Adviser can override any price that it believes is not consistent with market conditions. Valuation adjustments are limited to those necessary to ensure that the financial instrument's fair value is adequately representative of the price that would be received or paid in the marketplace. These adjustments include amounts that reflect counterparty credit quality, constraints on liquidity, and unobservable parameters that are applied consistently.

The Investment Adviser has established a Valuation Committee (the "Committee") which is responsible for overseeing the pricing and valuation of all securities held by the Fund. The Committee operates under pricing and valuation policies and procedures established by the Investment Adviser and approved by the Board. The policies and procedures set forth the mechanisms and processes to be employed on a daily basis related to the valuation of portfolio securities for the purpose of determining the NAV of the Fund. The Committee reports to the Board on a regular basis. At December 31, 2025, no portfolio securities were fair valued by the Committee.

GAAP provides a framework for measuring fair value and expands disclosures about fair value measurements and requires disclosure surrounding the various inputs that are used in determining the fair value of the Fund's investments. These inputs are summarized in three broad levels listed below:

•

Level 1 - Quoted prices in active markets for identical assets and liabilities at the measurement date. An active market is one in which transactions for the assets occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

•

Level 2 - Significant inputs other than quoted prices included in Level 1 that are observable (including quoted prices for similar securities, interest rates, pre-paymentspeeds, credit risk, etc.), either directly or indirectly.

•

Level 3 - Significant unobservable inputs, for example, inputs derived through extrapolation that cannot be corroborated by observable market data. These will be developed based on the best information available in the circumstances, which might include UBSTC's own data. Level 3 inputs will consider the assumptions that market participants would use in pricing the asset, including assumptions about risk (e.g., credit risk, model risk, etc.).

Securities and other assets that cannot be priced according to the methods described above are valued based on policies and procedures approved by the Committee. In the event that unobservable inputs are used when determining such valuations, the securities will be classified as Level 3 in the fair value hierarchy. Altering one or more unobservable inputs may result in a significant change to a Level 3 security's fair value measurement. The Fund maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available. Fair value is based upon quoted market prices when available.

The estimated fair value may be subjective in nature and may involve uncertainties and matters of significant judgment for certain financial instruments. Changes in the underlying assumptions used in calculating fair value could significantly affect the results. Therefore, the estimated fair value may materially differ from the value that could actually be realized on sale.

The inputs and methodology used for valuing securities or level assigned are not necessarily an indication of the risk associated with investing in those securities.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

Following is a description of the Fund's valuation methodologies used for assets and liabilities measured at fair value:

Puerto Rico Taxable Obligations: Prices for these securities are obtained from third-party service providers. Third-party service providers use a pricing methodology based on observable market inputs. These securities trade in over-the-countermarkets. Quoted prices are based on recent trading activity for similar instruments. These bonds are classified as Level 2.

Mortgage and Other Asset-Backed Securities: Fair value for these securities is mostly obtained from third-party pricing service providers that use a pricing methodology based on observable market inputs. Certain agency, mortgage, and other asset-backed securities ("MBS") are priced based on a bond's theoretical value from similar bonds, the term "similar" being defined by credit quality and market sector. Their fair value incorporates an option adjusted spread. The agency MBS are classified as Level 2.

U.S. Municipal Obligations: The fair value of U.S. municipal obligations is obtained from third-party pricing service providers that use a pricing methodology based on an active exchange market and quoted market prices for similar securities. These securities are classified as Level 2.

Futures contracts: Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade and are classified as Level 1.

The following is a summary of the portfolio by inputs used as of December 31, 2025, in valuing the Fund's assets carried at fair value:


	Investments in Securities
	Level 1		Level 2		Level 3		Balance 12/31/2025

There were no Level 3 securities during the fiscal year ended December 31, 2025.

There were no transfers into or out of Level 3 during the fiscal year ended December 31, 2025.

Taxation

As a registered investment company under the 1940 Act, the Fund will not be subject to Puerto Rico income tax for any taxable year if it distributes at least 90% of its taxable net investment income for such year, as determined for these purposes pursuant to section 1112.01(a)(2) of the Puerto Rico Internal Revenue Code of 2011, as amended. Accordingly, as the Fund intends to meet this distribution requirement, the income earned by the Fund is not subject to Puerto Rico income tax at the Fund level.

The Fund can invest in taxable and tax-exemptsecurities. In general, distributions of taxable income dividends, if any, to Puerto Rico individuals, estates, and trusts are subject to a Puerto Rico withholding tax of 15% of the dividends distributed if certain requirements are met. Puerto Rico tax withholdings are effected at the time of payment of the corresponding dividend. Individual shareholders may be subject to a Puerto Rico alternate basic tax on certain Fund distributions. Certain Puerto Rico entities receiving taxable income dividends are entitled to claim an 85% dividends received deduction.

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

Moreover, distribution of capital gains dividends, if any, to (a) Puerto Rico individuals, estates, and trusts are subject to a Puerto Rico income tax of 15% of the dividends distributed, and (b) Puerto Rico corporations are subject to a Puerto Rico income tax of 20% of the dividends distributed. Fund shareholders are advised to consult their own tax advisers.

For U.S. federal income tax purposes, the Fund is treated as a foreign corporation and does not intend to be engaged in a trade or business within the United States. As a foreign corporation not engaged in a trade or business in the United States, the Fund should generally not be subject to U.S. income tax on gains derived from the sale or exchange of personal property. Nevertheless, if it is determined that the Fund is engaged in a trade or business within the United States for purposes of the U.S. Internal Revenue Code of 1986, as amended ("U.S. Code"), and the Fund has taxable income that is effectively connected with such U.S. trade or business, the Fund will be subject to regular U.S. corporate income tax on its effectively connected taxable income, and maybe to a 30% branch profits tax and state and local taxes as well. Also, the Fund is subject to a 30% U.S. withholding tax on certain types of income from sources within the U.S., such as dividends and interest.

An investment in the Fund is designed solely for Puerto Rico residents due to the Fund's specific tax features. The Fund does not intend to qualify as a Regulated Investment Company ("RIC") under Subchapter M of the U.S. Code, and consequently an investor that is not (i) an individual who has his or her principal residence in Puerto Rico or (ii) a person, other than an individual, that has its principal office and principal place of business in Puerto Rico will not receive the tax benefits of an investment in a typical U.S. mutual fund (such as "RIC" tax treatment, i.e., availability of pass-through tax status for non-PuertoRico residents) and may have adverse tax consequences for U.S. federal income tax purposes. If United States holders (which includes, but is not limited to, (i) citizens and residents of the United States who are not Puerto Rico individuals and (ii) corporations organized in the United States) invest in the Fund, such United States holders generally will be taxed on any dividend or interest paid by the Fund as ordinary income at the time such holders receive the dividend or interest or when it accrues, depending on such holder's method of accounting for tax purposes. Additionally, United States holders will be taxed on any gain on the sale of an investment in the Fund.

FASB Accounting Standards Codification Topic 740, Income Taxes (ASC 740) requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not"of being sustained by the applicable tax authority. Tax positions not deemed to meet the "more-likely-than-not"threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Fund's tax positions taken on its Puerto Rico income tax returns for all open tax years (the prior four tax years) and has concluded that there are no uncertain tax positions. On an ongoing basis, management will monitor the Fund's tax position to determine if adjustments to this conclusion are necessary. The Fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expenses in the Statement of Operations. During the fiscal year ended December 31, 2025, the Fund did not incur any interest or penalties.

Statement of Cash Flows

The Fund issues its shares, invests in securities, and distributes dividends from net investment income and net realized gains which are paid in cash. These activities are reported in the Statement of Changes in Net Assets. Additional information on cash receipts and payments is presented in the Statement of Cash Flows.

Accounting practices that do not affect the reporting of activities on a cash basis include carrying investments at fair value and amortizing premiums or discounts on debt obligations. Cash, as presented on the Statement of Assets and Liabilities, does not include short-term investments.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

Dividends and Distributions to Shareholders

The Fund intends to distribute to its shareholders substantially all of its net investment income. However, the Fund may elect to distribute less of its net investment income if, in the judgment of the Investment Adviser, such reduced distribution is in the best economic interests of the Fund's shareholders. Such distributions, if any, shall be paid by the Fund on no less than a monthly basis. Distributions on shares will be reinvested at the NAV per share determined on the ex-dividenddate.

Futures Contracts

Futures contracts provide for the future exchange of a specified security at a specified future time and at a specified price. Upon entering into a financial futures contract, the Fund is required to pledge to a Futures Commission Merchant (FCM), an amount per contract as determined by an exchange of cash, U.S. government securities, or other assets, otherwise known as "initial margin". Subsequent payments, known as variation margin, are made or received by the Fund each day, depending on the daily fluctuations in the price of the futures contract. The Fund recognizes an unrealized gain or loss equal to the aggregate daily variation margin until the contract is closed out, at which time the Fund realizes a gain or loss. There are several risks accompanying the utilization of futures contracts. Positions in futures contracts may be closed only on an exchange. While the Fund plans to utilize futures contracts only if there exists an active market for such contracts, there is no guarantee that a liquid market will exist for the contracts at a specified time.

Furthermore, because, by definition, futures contracts reflect expectations of projected reference instrument or index price levels, and not necessarily current market levels, circumstances may result in discrepancies between changes in the price of the futures contract and the movement in the reference instrument or index. The absence of a perfect price correlation between the futures contract and its underlying instrument or index could stem from, among other things, changing assumptions regarding the financing cost of the underlying instrument or index, changing assumptions regarding the implied volatility of the underlying index or instrument, and/or changing assumptions regarding the ease of sourcing the instrument or index for eventual delivery into the futures contract.

The Fund utilizes U.S. treasury short futures contracts that are traded at the Chicago Mercantile Exchange (CME), a registered futures exchange. By investing in short futures contracts, the Investment Adviser seeks to alter the interest rate sensitivity, also known as duration, of the Fund. The relationship between interest rates on the underlying assets of the Fund and on the value of short futures contracts may or may not remain constant. As a result, the use of short futures may or may not alter the interest rate sensitivity of the Fund as expected by the Investment Advisor and may result in unexpected gains or losses. There were no futures contracts outstanding as of December 31, 2025.

Reverse Repurchase Agreements

Under these agreements, the Fund sells portfolio securities, receives cash in exchange, and agrees to repurchase the securities at a mutually agreed upon date and price. Ordinarily, those counterparties with which the Fund enters into these agreements require delivery of collateral, nevertheless, the Fund retains effective control over such collateral through the agreement to repurchase the collateral on or by the maturity of the reverse repurchase agreement. These transactions are treated as financings and recorded as liabilities. Therefore, no gain or loss is recognized on the transaction, and the securities pledged as collateral remain recorded as assets of the Fund. The Fund enters into reverse repurchase agreements that do not have third-party custodians, with the collateral delivered directly to the counterparty. Pursuant to the terms of the standard Securities Industry and Financial Markets Association (SIFMA) Master Repurchase Agreement, the counterparty is free to repledge or rehypothecate the collateral, provided it is delivered to the Fund upon maturity of the reverse repurchase agreement. This arrangement allows the Fund to receive better interest rates and pricing on the reverse repurchase agreements. While the Fund cannot monitor the rehypothecation of collateral, it does monitor the market value of the collateral versus the repurchase amount, that the

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

income from the collateral is paid to the Fund on a timely basis, and that the collateral is returned at the end of the reverse repurchase agreement. These agreements involve the risk that the market value of the securities purchased with the proceeds from the sale of securities received by the Fund may decline below the price of the securities that the Fund is obligated to repurchase, and that the value of the collateral posted by the Fund increases in value and the counterparty does not return it. Because the Fund borrows under reverse repurchase agreements based on the estimated fair value of the pledged assets, the Fund's ongoing ability to borrow under its reverse repurchase facilities may be limited, and its lenders may initiate margin calls in the event of adverse changes in the market. A decrease in market value of the pledged assets may require the Fund to post additional collateral or otherwise sell assets at a time when it may not be in the best interest of the Fund to do so. There were no reverse repurchase agreements outstanding as of December 31, 2025.

Preferred Shares

Pursuant to the Fund's Certificate of Incorporation, as amended and supplemented, the Fund's Board is authorized to issue up to 12,000,000 preferred shares with a par value of $25, in one or more series. During the fiscal year ended December 31, 2025, no preferred shares were issued or outstanding.

Operating Segments

In this reporting period, the Fund adopted FASB Accounting Standards Update 2023-07,Segment Reporting ("Topic 280") - Improvements to Reportable Segment Disclosures (ASU 2023-007).Adoption of the new standard impacted financial statement disclosures only and did not affect the Fund's financial position or the results of its operations. ASU 2023-07is effective for fiscal years beginning after December 15, 2023, and required retrospective application for all periods presented within the financial statements.

An operating segment is defined in Topic 280 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 asses its performance, and has discrete financial information available. The Asset Liability Committee ("ALCO") of the Fund's Investment Adviser acts as the Fund's CODM. Since its commencement, the Fund operates and is managed as a single operating segment, as the CODM monitors the operating results of the Fund as a whole and the Fund's long-term strategic portfolio allocation is pre-determinedin accordance with the term of its prospectus, based on a defined investment strategy which is executed by the Fund's portfolio managers as a team. The financial information in the form of the Fund's portfolio investments, geographic allocation, leverage, net investment income, total return, expense ratio and changes in net assets resulting from operations and net subscriptions and redemptions, which are used by the CODM to assess the segment's performance versus the Fund's comparative benchmark and to make resource allocation decisions for the Fund's single segment is consistent with that presented within the Fund's financial statements. The accounting policies of the Fund are consistent with those described in these Notes to Financial Statements. Segment assets are reflected on the accompanying Statements of Assets and Liabilities as "total assets" and significant segment expenses are listed on the accompanying Statement of Operations.

Other

Security transactions are accounted for on a trade date plus one basis (T+1) for daily NAV calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Realized gains and losses on security transactions are determined on the identified cost method. Premiums and discounts on securities purchased are amortized using the interest method over the life or the expected life of the respective securities. Premiums are amortized at the earliest call date for any applicable securities. Interest and dividend income is accrued on a daily basis, except when collection is not expected.

6.	Line of Credit

Effective on August 5, 2015, the Fund granted Societe Generale, a French multinational banking and financial services company with headquarters in Paris, a security interest pursuant to the Credit Agreement between the Fund and Societe Generale (the "Credit" Agreement"). The Fund agrees to provide, and at all times maintain, adequate margin in the account pursuant to the terms and conditions of the Credit Agreement. Upon notice from Societe Generale that the value of the pledged assets is less than the margin required by Societe Generale under the Credit Agreement, the Fund shall deposit in the account additional property acceptable to Societe Generale with a value sufficient to remedy such deficiency. For the fiscal year ended December 31, 2025, the Fund had a line of credit amounting to $40,000,000. The related debt outstanding at December 31, 2025, was $9,600,000. The amount of unused credit, subject to the Credit Agreement, at December 31, 2025, was $30,400,000 and related information is as follows:


Weighted average interest rate at end of the year		4.66%
Maximum aggregate balance outstanding at any time of the year		$12,000,000
Average balance outstanding during the year		$9,283,425
Average interest rate during the year		5.14%

During the fiscal year ended December 31, 2025, interest rates on the line of credit ranged from 4.56% to 5.41%.

At December 31, 2025, investment securities amounting to $27,900,118, were pledged as collateral for the line of credit. Interest payable on the line of credit with Societe Generale amounted to $1,243 at December 31, 2025.

7.	Concentration of Credit Risk

Concentration of credit risk that arises from financial instruments exists for groups of customers or counterparties when they have similar economic characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in economic or other conditions.

The major concentration of credit risk arises from the Fund's investment securities in relation to the location of the issuers of such investment securities. For calculating concentration, all securities guaranteed by the U.S. government or any of its subdivisions are excluded. At December 31, 2025, the Fund had investments with an aggregate fair value of approximately $8,467,956, which were issued by corporate entities located in the Commonwealth of Puerto Rico and are not guaranteed by the Puerto Rico government, the U.S. government or any of its subdivisions. Also, at December 31, 2025, the Fund had investments with an aggregate fair value amounting to $56,219,175, which were

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

issued by various municipalities located in the United States and not guaranteed by the U.S. government.

8.	Investment and Other Requirements and Limitations

The Fund is subject to certain requirements and limitations related to investments and leverage. Some of these requirements and limitations are imposed by statute or by regulation, while others are imposed by procedures established by the Board. The most significant requirements and limitations are discussed below.

Under normal circumstances, the Fund will invest at least 20% of its total assets in taxable securities issued by Puerto Rico issuers. In addition, up to 80% of its total assets will be invested primarily in United States municipal securities.

As a fundamental policy, the Fund may not borrow money, except as permitted under the 1940 Act, or issue senior securities to the extent such issuance would violate the 1940 Act. The 1940 Act permits the Fund to borrow money in amounts of up to one-thirdof the Fund's total assets from banks for any purpose, and to borrow up to 5% of the Fund's total assets from banks or other lenders for temporary purposes, including to finance redemptions. The 1940 Act requires the Fund to maintain at all times an "asset coverage" of at least 300% of the amount of its borrowings.

As its investment policy, under normal conditions at least 95% of the Fund's total assets will be invested in securities which, at the time of purchase, are rated investment grade by a nationally recognized statistical rating organization, or which are determined by the Fund's Investment Adviser or Sub-Adviserto be of comparable credit quality.

9.	Tax Basis of Distributions and Components of Distributable Earnings (Accumulated Losses)

The amount of net unrealized appreciation/(depreciation) and the cost of investment securities for tax purposes was as follows:


Cost of investments for tax purposes	$	75,717,774
Gross appreciation		96,287
Gross depreciation		(6,267,978	)
Net appreciation (depreciation)	$	(6,171,691	)

In order to maintain a stable level of dividends however, the Fund may at times pay more or less than the net investment income earned in a particular year.

For the fiscal years ended December 31, 2025, and December 31, 2024, the Fund had distributed from ordinary income $2,299,929 and $2,356,921 for tax purposes, respectively. The undistributed net investment income at December 31, 2025, and December 31, 2024, was as follows:

10.	Risks and Uncertainties

The Fund is exposed to various types of risks, such as geographic concentration, industry concentration, non-diversification,interest rate, and credit risks, among others. This list is qualified in its entirely by reference to the more detailed information provided in the offering documentation for securities issued by the Fund.

Investment and Market Risk. The Fund's investments may be adversely affected by the performance of U.S. and Puerto Rico investment securities markets, which, in turn, may be influenced by a number of factors, including, among other things, (i) the level of interest rates, (ii) the rate of inflation, (iii) political decisions, (iv) fiscal policy, and (v) current events in general. All securities may be subject to adverse market trends. The value and liquidity of the Fund's portfolio holdings may fluctuate in response to events specific to the companies or stock or bond markets in which a Fund invests, as well as economic, political, or social events in the United States, Puerto Rico, or abroad. Markets can be volatile, and values of individual securities and other investments at times may decline significantly and rapidly. This may cause the Fund's portfolio to be worth less than the price originally paid for it, or less than it was worth at an earlier time. Market risk may affect a single issuer or the market as a whole. As a result, a portfolio of such securities may underperform the market as a whole. Recent market conditions and events, including a global public health crisis and actions taken by governments in response, may exacerbate such volatility and may continue to negatively affect the value and liquidity of individual securities, national economies, and global markets generally. Rapid changes in value or liquidity, which often are not anticipated and can relate to events not connected to particular

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

investments, may limit the ability of the Fund to dispose of its assets at the value or time of its choosing and can result in losses. Because the Fund invests in investment securities, the Fund's NAV may fluctuate due to market conditions and as a result you may experience a decline in the value of your investment in the Fund and you may lose money.

An investment in shares of the Fund is designed primarily for, and is suitable only for long-term investors, and is not suitable for all investors.

Puerto Rico and other countries and regions in which the Fund may invest where the Investment Adviser has offices or where the Fund or the Investment Adviser otherwise do business are susceptible to natural disasters (e.g., fire, flood, earthquake, storm, and hurricane), epidemics/pandemics, or other outbreaks of serious contagious diseases. The occurrence of a natural disaster or epidemic/pandemic could, directly or indirectly, adversely affect and severely disrupt the business operations, economies, and financial markets of many countries (even beyond the site of the natural disaster or epidemic/pandemic) and could adversely affect the Fund's investment program or the Investment Adviser's ability to do business. In addition, terrorist attacks, or the fear of or the precautions taken in anticipation of such attacks, could, directly or indirectly, materially and adversely affect certain industries in which the Fund invests or could affect the countries and regions in which the Fund invests, where the Investment Adviser has offices or where the Fund or the Investment Adviser otherwise do business. Other acts of war (e.g., invasion, acts of foreign enemies, hostilities, and insurrection, regardless of whether war is declared) could also have a material adverse impact on the financial condition of industries or countries in which the Fund invests.

In addition, turbulence in financial markets and reduced liquidity in equity and/or fixed-income markets may negatively affect the Fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region, or financial market may adversely impact issuers in a different country, region, or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain and could affect companies worldwide. An outbreak of an infectious disease or serious environmental or public health concern could have a significant negative impact on economic and market conditions, could exacerbate pre-existingpolitical, social, and economic risks in certain countries or regions, and could trigger a prolonged period of global economic slowdown, which may impact the Fund. To the extent the Fund is overweight in certain countries, regions, companies, industries, or market sectors, such positions will increase the risk of loss from adverse developments affecting those countries, regions, companies, industries, or sectors.

Counterparty Risk. The Fund may engage in financial transactions directly with other counterparties. This subjects the Fund to credit risk that a counterparty will default on an obligation to the Fund. Such a risk contrasts with transactions done through exchange markets, wherein credit risk is reduced through the collection of variation margin and through the interposition of a clearing organization as the guarantor of all transactions. Clearing organizations transform the credit risk of individual counterparties into the more remote risk of the failure of the clearing organization.

Fixed Income Securities Generally. The yield on fixed income securities such as those in which the Fund may invest depends on a variety of factors, including general market conditions for such securities, the financial condition of the issuer, the size of the particular offering, and the maturity, credit quality, and rating of the security. Generally, the longer the maturity of those securities, the higher its yield and the greater the changes in its yields both up and down. The market value of fixed income securities normally will vary inversely with changes in interest rates. Such changes in the Fund's NAV, in particular, also might affect the price of its shares. The unique characteristics of certain types of securities may also make them more sensitive to changes in interest rates.

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

Extension Risk. Extension risk is the risk that during periods of rising interest rates, the average life of certain types of securities may be extended because of the right of the issuer to defer payments or make slower than expected principal payments. This may lock in a below market interest rate, increase the security's duration (the estimated period until the security is paid in full) making it more sensitive to changes in interest rates, and reduce the value of the security. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.

Prepayment Risk. Prepayment risk is the risk that during periods of declining interest rates, the issuer of a security may exercise its option to pay principal earlier than scheduled in order to refinance at lower interest rates, forcing the Fund to reinvest in lower yielding securities. Prepayment reduces the yield to maturity and the average life of the security and also increases price fluctuation. This tendency of issuers to refinance debt with high interest rates during periods of declining interest rates may reduce the positive effect of declining interest rates on the market value of the Fund's securities.

Municipal Securities Market Risk. Municipal securities are obligations, often bonds and notes, issued by or on behalf of states, territories, and possessions of the United States and the District of Columbia and their political subdivisions, agencies, authorities, and instrumentalities, the interest on which is typically exempt from federal income tax. Under normal circumstances, up to 80% of the Fund's net assets, plus the amount of any borrowings for investment purposes, will be invested in U.S. municipal securities, which may include investments in Build America Bonds ("BABs") and taxable municipal securities (i.e., municipal securities that are generally taxable to non-PuertoRico residents). From time to time, proposals to restrict or eliminate the federal income tax exemption from interest on municipal securities are introduced before Congress. Proposals also may be introduced before state legislatures. If such proposals were enacted, the availability of municipal securities and their value would be affected.

Municipal bonds are generally considered riskier investments than Treasury securities. The prices and yields on municipal securities are subject to change from time to time and depend upon a variety of factors, including general money market conditions, the financial condition of the issuer (or other entities whose financial resources are supporting the municipal security), general conditions in the market for tax-exemptobligations, the size of a particular offering, and the maturity of the obligation and the rating(s) of the issue.

Municipal securities risks include the ability of the issuer to repay the obligation, the relative lack of information about certain issuers of municipal securities, and the possibility of future legislative changes which could affect the market for and value of municipal securities. Certain municipal securities, including private activity bonds, are not backed by the full faith, credit, and taxing power of the issuer. Additionally, if events occur after the security is acquired that impact the security's tax-exemptstatus, the Fund and its shareholders could be subject to substantial tax liabilities.

Certain of the municipal obligations in which the Fund may invest present their own distinct risks. These risks may depend, among other things, on the financial situation of the government issuer, or, in the case of industrial development bonds and similar securities (including certain bonds offered by the Puerto Rico Industrial, Tourist, Educational, Medical and Environmental Control Facilities Financing Authority), on that of the entity supplying the revenues that are intended to repay the obligations. It is also possible that, as a result of litigation or other conditions, the power or ability of issuers or those other entities to meet their obligations for the repayment of principal and payment of interest may be materially and adversely affected.

The amount of public information available about the municipal securities in the Fund's portfolio is generally less than that for corporate equities or bonds, and the Fund's investment performance may therefore be more dependent on the Investment Adviser's and Sub-Adviser'sanalytical abilities. The

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

secondary market for municipal securities, particularly the below investment grade municipal securities in which the Fund may invest, also tends to be less developed or liquid than many other securities markets, which may adversely affect the Fund's ability to sell its municipal securities at attractive prices.

BABs Risk. The BABs market is smaller and less diverse than the broader municipal securities market. In addition, BABs may experience less liquidity than other types of municipal securities. The number of BABs available in the market is limited and there can be no assurance that BABs will be actively traded. Reduced liquidity may negatively affect the value of the BABs.

Because issuers of direct-payBABs held in the Fund's portfolio receive reimbursement from the U.S. Treasury with respect to interest payment on bonds, there is a risk that those municipal issuers will not receive timely payment from the U.S. Treasury and may remain obligated to pay the full interest due on direct pay BABs held by the Fund. Furthermore, it is possible that a municipal issuer may fail to comply with the requirements to receive the direct-paysubsidy or that a future Congress may terminate the subsidy altogether.

Certain aspects of the BABs program may be subject to additional federal or state level guidance or subsequent legislation. For example, the U.S. Internal Revenue Service ("IRS") or U.S. Treasury could impose restrictions or limitations on the payments received. Aspects of the BABs program for which the IRS and the U.S. Treasury have solicited public comment include, but have not been limited to, methods for making direct payments to issuers, the tax procedural framework for such payments, and compliance safeguards. It is not known what additional procedures will be implemented with respect to direct-payBABs, if any, nor is it known what effect such possible procedures would have on the BABs market.

The Fund may invest significantly in BABs, and if it does, the Fund's NAV may be more volatile than the value of a more broadly diversified portfolio and may fluctuate substantially over short periods of time. Because BABs do not include certain industries or types of municipal bonds (i.e., tobacco bonds or private activity bonds), there may be less diversification than with a broader pool of municipal securities.

Collateralized Mortgage Obligations ("CMO") Risk. CMOs exhibit similar risks to those of MBS but also present certain special risks. CMOs are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams ("tranches") with different priority rights to portions of the underlying mortgage payments. Certain CMO tranches may represent a right to receive interest only (IOs), principal only (POs), or an amount that remains after floating-rate tranches are paid (an inverse floater). CMO classes may be specially structured in a manner that provides a variety of investment characteristics, such as yield, effective maturity, and interest rate sensitivity. As market conditions change, however, particularly during periods of rapid or unanticipated changes in interest rates, the ability of a CMO class to provide the anticipated investment characteristics and performance may be significantly reduced. If the Fund invests in CMO tranches (including CMO tranches issued by government agencies) and interest rates move in a manner not anticipated by Fund management, it is possible that the Fund could lose all or substantially all of its investment. These changes may result in volatility in the market value and in some instances reduced liquidity of the CMO class.

Asset-Backed Securities Risk. Asset-backed securities represent interests in "pools" of assets, including consumer loans or receivables held in trust. The receivables supporting asset-backed securities are generally automobile and credit card receivables but may also consist of other types of obligations. Asset-backed securities and the underlying receivables are not generally insured or guaranteed by any government agency. However, in certain cases, such securities are collateralized

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

by loans guaranteed by the U.S. Small Business Administration ("SBA"). The SBA is an independent agency of the United States. Asset-backed securities present risks similar to those of MBS. However, in the case of many asset-backed securities, the prepayment rates on the underlying assets have historically been less influenced by market interest rate fluctuations and therefore have been more stable. The frequent absence of a government guarantee creates greater exposure to the credit risk on the underlying obligations and depending on the structure, the credit risk of the sponsor of such obligations.

Asset-backed securities entail certain risks not presented by MBS, including the risk that in certain states it may be difficult to perfect the liens securing the collateral backing certain asset-backed securities. In addition, certain asset-backed securities are based on loans that are unsecured, which means that there is no collateral to seize if the underlying borrower defaults.

Leverage Risk. The Fund borrows money from banks to buy securities and pledges its assets in connection with the borrowing. If the interest expense of the borrowing is greater than the return on the securities bought, the use of leverage will decrease the return to shareholders in the Fund. Use of leverage also tends to magnify the volatility of the Fund's returns. The greater the use of leverage by the Fund, the greater the risk of the volatility of the Fund's returns. In addition, because the fees received by the Investment Adviser and Sub-Adviserare based on the average daily gross assets (including any assets attributable to borrowings), the Investment Adviser and the Sub-Adviserhave a financial incentive for the Fund to use certain forms of leverage, which may create a conflict of interest between the Investment Adviser and the Sub-Adviseron the one hand, and shareholders on the other hand.

Puerto Rico Risk. At least 20% of the Fund's total assets are expected to be invested in securities of Puerto Rico issuers. As a result, the Fund's NAV and cash flow may fluctuate due to market conditions affecting these securities. In addition, securities issued by the government of the Commonwealth of Puerto Rico, or its instrumentalities, are affected by the central government's finances. That includes, but is not limited to, general obligations of Puerto Rico and revenue bonds, special tax bonds, or agency bonds. Over the past few years, many Puerto Rico government bonds as well as the securities issued by several Puerto Rico financial institutions have been downgraded as a result of several factors, including without limitation, the downturn experienced by the Puerto Rico economy and the strained financial condition of the Puerto Rico government. Currently, the Puerto Rico bond market is experiencing a period of volatility, with Puerto Rico bonds trading at historically lower prices and higher yields. Any future developments in this respect could result in additional interruptions in cash flow on debt payments, which may result in more price volatility across Puerto Rico securities. There can be no assurance that any additional defaults by the Commonwealth of Puerto Rico and other Commonwealth instrumentalities will not have an additional adverse impact on the Fund's net investment income.

The Fund's ability to achieve its investment objective depends in part on the availability of Puerto Rico obligations. If those obligations are unavailable or are only available at a price unreasonably above their market value or at interest rates inconsistent with the Fund's investment objective, it may harm the Fund's performance.

There presently are a limited number of participants in the market for certain securities of Puerto Rico issuers. In addition, certain Puerto Rico securities may have periods of illiquidity. These factors may affect the Fund's ability to acquire or dispose of such securities, as well as the price paid or received upon such acquisition or disposition.

Interest Rate Risk. The value of fixed income securities, such as those in which Fund may invest, generally fall when interest rates rise and rise when interest rates fall. Interest rate risk is the risk that

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

interest rates will rise, and as a result, the value of the Fund's investments will fall. Prices of intermediate and long-term fixed income securities generally change more in response to interest rate changes than prices of shorter-term fixed income securities. To the extent the Fund invests primarily in intermediate and long-term fixed income securities, the NAV of the Fund's Shares will fluctuate more in response to changes in market interest rates than if the Fund invested primarily in shorter-term fixed income securities. A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from mutual funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund's performance.

Credit Risk. Credit risk is the risk that debt securities or preferred stock will decline in price or fail to make dividend or interest payments when due because the issuer of the security experiences a decline in its financial condition. Changes in an issuer's credit rating or the market's perception of an issuer's creditworthiness may also affect the value of the Fund's investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

Risks of Reverse Repurchase Agreements. The Fund may engage in reverse repurchase agreements which are collateralized loan transactions in which the Fund sells a portfolio security to a counterparty in exchange for cash and agrees to buy it back at a specified time and price in a specified currency. The counterparty can repledge or rehypothecate the collateral securities to a third party, provided they are delivered to the Fund upon maturity of the reverse repurchase agreement. Reverse repurchase agreements involve various risks to the Fund. Reverse repurchase agreements are subject to counterparty risk that the buyer of the securities sold by the Fund, or the counterparty to which the buyer rehypothecates the collateral securities may be unable to deliver the securities at the agreed upon terms when the Fund seeks to repurchase the collateral. In that case, the Fund may be unable to purchase the securities on the open market or only at a higher cost, possibly resulting in an investment loss to the Fund. The collateral securities in the reverse repurchase agreement are also subject to market risk. An increase in interest rates that causes a decrease in the market value of the securities can lead the lenders to require the Fund to post additional collateral at a time when it may not be in the best interest of the Fund to do so.

MBS Risk. MBS (residential and commercial) represent interests in "pools" of mortgages. MBS have many of the risks of traditional debt securities but, in general, differ from investments in traditional debt securities in that, among other things, principal may be prepaid at any time due to prepayments by the obligors on the underlying obligations. As a result, the Fund may receive principal repayments on these securities earlier or later than anticipated by the Fund. In the event of prepayments that are received earlier than anticipated, the Fund may be required to reinvest such prepayments at rates that are lower than the anticipated yield of the prepaid obligation. The rate of prepayments is influenced by a variety of economic, geographic, demographic, and other factors, including, among others, prevailing mortgage interest rates, local and regional economic conditions, and homeowner mobility. Generally, prepayments will increase during periods of declining interest rates and decrease during periods of rising interest rates. The decrease in the rate of prepayments during periods of rising interest rates results in the extension of the duration of MBS, which makes them more sensitive to changes in interest rates and more likely to decline in value (this is known as extension risk).

Illiquid Securities. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid investments. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less, without the sales or dispositions significantly changing the market value of the investment. There presently are a limited number of participants in the market for certain Puerto Rico securities or other securities or assets that the Fund may own. That and other factors may cause certain securities to have periods of illiquidity.

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

Illiquid securities include, among other things, securities subject to legal or contractual restrictions on resale that hinder the marketability of the securities.

Special Risks of Hedging Strategies. The Fund may use a variety of derivatives instruments including securities options, financials futures contracts, options on futures contracts, and other interest rate protection transactions such as swap agreements, to attempt to hedge its portfolio of assets and enhance its return. Successful use of most derivatives instruments depends upon the Investment Adviser's or Sub-Adviser'sability to predict movements of the overall securities and interest rate markets. There is no assurance that any particular hedging strategy adopted will succeed or that the Fund will employ such strategy with respect to all or any portion of its portfolio. Some of the derivative strategies that the Fund may use to enhance its return are riskier than its hedging transactions and have speculative characteristics. Such strategies do not attempt to limit the Fund's risk of loss.

Derivatives Risk. The Fund's use of derivatives increases the Fund's exposure to the following risks:

Volatility Risk - A risk of the Fund's use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets.

Counterparty Risk - Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.

Illiquid Securities Risk - The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.

Valuation Risk - Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them.

Tax Risk - Certain aspects of the tax treatment of derivative instruments, including swap agreements, are currently unclear and may be affected by changes in legislation, regulations, or other legally binding authority. Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character, and amount of income the Fund realizes from its investments.

Regulatory Risk - Derivative contracts, including, without limitation, swaps, currency forwards, and non-deliverableforwards are subject to regulation under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") in the United States and under comparable regimes in Europe, Asia, and other non-U.S.jurisdictions. Under the Dodd-Frank Act, certain derivatives are subject to margin requirements and swap dealers are required to collect margin from the Fund with respect to such derivatives. Specifically, regulations are now in effect that require swap dealers to post and collect variation margin (comprised of specified liquid instruments and subject to a required haircut) in connection with trading of over-the-counter("OTC") swaps with the Fund. Shares of investment companies (other than certain money market funds) may not be posted as collateral under these regulations. Requirements for posting of initial margin in connection with OTC swaps will be phased-inthrough at least 2021. In addition, regulations adopted by global prudential regulators that are now in effect require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many derivatives contracts, terms that delay or restrict the rights of counterparties, such as the Fund, to terminate such contracts, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. The implementation of these requirements with respect to derivatives, as well as regulations under the Dodd-Frank Act regarding clearing, mandatory trading, and margining of other derivatives may increase the costs

U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Notes to Financial Statements

For the fiscal year ended December 31, 2025

and risks to the Fund of trading in these instruments and, as a result, may affect returns to investors in the Fund.

The SEC has adopted new regulations governing the use of derivatives by registered investment companies ("Rule 18f-4").Rule 18f-4imposes limits on the amount of derivatives a fund can enter into, eliminates the asset segregation framework currently used by the funds to comply with Section 18 of the 1940 Act, treats derivatives as senior securities so that a failure to comply with the proposed limits would result in a statutory violation, and requires funds whose use of derivatives is more than a limited specified exposure amount to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager.

11.	Indemnifications

In the normal course of business, the Fund enters into contracts that contain a variety of indemnification clauses. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses for indemnification and expects the risk of loss to be remote.

12.	Subsequent Events

Events and transactions from January 1, 2026, through February 25, 2026 (the date the annual financial statements were available to be issued), have been evaluated by management for subsequent events. Management has determined that there were no material events that would require adjustment to or additional disclosure in the Fund's financial statements through this date, except as disclosed below.

To the Shareholders and the Board of Directors of U.S. Monthly Income Fund for Puerto Rico Residents, Inc.

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of U.S. Monthly Income Fund for Puerto Rico Residents, Inc. (the "Fund"), including the schedule of investments, as of December 31, 2025, and the related statements of operations and cash flows for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund at December 31, 2025, the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of the Fund's internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2025, by correspondence with the custodian, brokers and others. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

We have served as the auditor of one or more UBS investment companies since 1978.

OTHER INFORMATION (Unaudited)

FUND LEVERAGE

THE BENEFITS AND RISKS OF LEVERAGE

As a fundamental policy, the Fund may only issue senior securities, as defined in the 1940 Act ("Senior Securities"), representing indebtedness to the extent that immediately after their issuance, the value of its total assets, less all the Fund's liabilities and indebtedness that are not represented by Senior Securities being issued or already outstanding, is equal to or greater than the total of 300% of the aggregate par value of all outstanding indebtedness issued by the Fund. The Fund may only issue Senior Securities representing preferred stock to the extent that immediately after any such issuance, the value of its total assets, less all the Fund's liabilities and indebtedness that are not represented by Senior Securities being issued or already outstanding, is equal to or greater than the total of 200% of the aggregate par value of all outstanding preferred stock (not including any accumulated dividends or other distributions attributable to such preferred stock) issued by the Fund. This asset coverage requirement must also be met any time the Fund pays a dividend or makes any other distribution on its issued and outstanding shares of common stock or any shares of its preferred stock (other than a dividend or other distribution payable in additional shares of common stock) as well as any time the Fund repurchases any shares of common stock, in each case after giving effect to such repurchase of shares of common stock or issuance of preferred stock, debt securities, or other forms of leverage in order to maintain asset coverage at the required 200% level. To the extent necessary, the Fund may purchase or redeem preferred stock, debt securities, or other forms of leverage in order to maintain asset coverage at the required 200% level. In such instances, the Fund will redeem Senior Securities, as needed, to maintain such asset coverage.

Subject to the above percentage limitations, the Fund may also engage in certain additional borrowings from banks or other financial institutions. In addition, the Fund may also borrow for temporary or emergency purposes, in an amount of up to an additional 5% of its total assets.

Leverage can produce additional income when the income derived from investments financed with borrowed funds exceeds the cost of such borrowed funds. In such an event, the Fund's net income will be greater than it would be without leverage. On the other hand, if the income derived from securities purchased with borrowed funds is not sufficient to cover the cost of such funds, the Fund's net income will be less than it would be without leverage.

To obtain leverage, the Fund has a $40 million line of credit with Société Generale, a French multinational banking and financial services company. Société Generale has obtained a security interest on the pledged collateral that consists of U.S. municipal bonds.

As of December 31, 2025, the Fund had the following leverage outstanding:


Borrowings under the Line of Credit		$9,600,000
Leverage Ratio*		13.4%

Refer to Schedule of Investments for details of the securities pledged as collateral and Note 6 of the Financial Statements for further details on the line of credit during the year. The leverage of the increased $1,400,000 during the year.

*Asset Leverage ratio: The aggregate principal amount of other borrowings by the Fund, including borrowings resulting from the issuance of any other series and other forms of leverage, and from the compliance date of Rule 18f-4going forward, including borrowings in the form of reverse repurchase agreements, divided by the fair market value of the assets of the Fund on any given day.
