**LETTER TO SHAREHOLDERS** 

March 20, 2026

Dear Shareholder:

Puerto Rico Residents Tax-Free Fund III, Inc. (the "Fund") is pleased to present this Letter to Shareholders for the period from September 1, 2025, to February 28, 2026.

After lowering the federal funds rate by a total of 1.00% during the last three meetings of calendar year 2024, the Federal Reserve Board (the "Fed") did not lower interest rates again until its September 2025 meeting. This 0.25% cut was followed by additional 0.25% cuts at the November and December meetings for a total of 0.75% during the calendar year 2025. The federal funds rate closed the Fund's fiscal year at 3.50% to 3.75%.

The yield curve flattened 0.17% during the period. The yield of the 2-year U.S. Treasury note decreased 0.11% during the period, closing at 3.51% versus 3.62% at the beginning of period. The yield of the 10-year U.S. Treasury note decreased 0.28%, closing the period at 3.95% versus 4.23% at the beginning of the period.

On February 20, 2026, the Supreme Court ruled that the tariffs imposed by the Trump Administration beginning in April 2025, were illegal. President Trump reacted by imposing a new 15% tariff using a different law. The impact of this ruling and the renewed efforts by the administration to continue to implement its tariff policy add uncertainty about the impact on the economy and most importantly inflation.

On February 28, 2026, the United States and Israel launched a military strike against Iran called "Operation Epic Fury". Iran countered by attacking U.S. targets in neighboring Arab countries, threatening to destabilize the whole region. Oil prices increased sharply in response. The yield on the U.S. 10-year note had decreased during the month of February, dropping to below 4% on February 27, 2026. It has increased since the start of the conflict as investors are focusing on the potential inflationary impact of the increase in the price of oil and other potential disruptions to trade. On March 20, 2026, the yield on the 10-year note closed at 4.39%, the highest level since July 2025.

Adding further uncertainty to the economic scenarios, there were additional conflicting reports on labor and inflation in March. On March 6, 2026, the labor report showed an unexpected drop of 92,000 in non-farm payrolls, raising additional questions about growth and the economy. The unemployment rate increased to 4.4%. On March 18, 2026, the Producer Price Index (PPI) for February 2026 was much higher than expected, increasing 0.7% for the month, and 3.4% year over year. This report signals persistent inflationary pressures in the supply chain.

The Fed left the fed funds rate unchanged at its March 18, 2026, meeting. In the statement following the meeting, the Fed used the word "uncertainty" twice, once to describe "the economic outlook" and a second time to describe "the implications for developments in the Middle East for the U.S. economy". During the press conference after the meeting, Fed Chairman Powell responded to questions on the impact of the war by reiterating that forecasting its impact is nearly impossible at that time.

Uncertainty over the timing of Fed policy, inflation expectations, the revised implementation of tariffs, the shape of the yield curve, and the evolving impact of the Iran conflict present a challenging environment for the management of the Fund. Notwithstanding, the investment adviser remains committed to seeking investment opportunities within allowed parameters while providing professional management services to the Fund for the benefit of its shareholders.

Sincerely,

/s/ Carlos Nido

Carlos Nido

Chairman of the Board of Directors

**MANAGEMENT DISCUSSION OF FUND PERFORMANCE** 

**REGISTRATION UNDER THE INVESTMENT COMPANY ACT OF 1940** 

The Fund is a non-diversified closed-end management investment company organized under the laws of the Commonwealth of Puerto Rico ("Puerto Rico") and is registered as an investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), as of May 21, 2021. Prior thereto, the Fund was registered under the Puerto Rico Investment Companies Act of 1954, as amended.

On May 24, 2018, the Economic Growth, Regulatory Relief, and Consumer Protection Act (Pub. L. No. 115-174) was signed into law and amended the 1940 Act to repeal the exemption from its registration of investment companies created under the laws of Puerto Rico, the U.S. Virgin Islands, or any other U.S. possession under Section 6(a)(1) thereof. The repeal of the exemption took effect on May 24, 2021. Upon registration under the 1940 Act, the Fund must now register its future offerings of securities under the Securities Act of 1933, as amended (the "1933 Act"), absent an available exception. There is limited trading in Fund shares, which are not registered under the 1933 Act, and are only traded via private transactions. The Fund has suspended the issuance of tax-exempt secured obligations ("TSOs") pending registration under the 1933 Act.

**FUND PERFORMANCE** 

The Fund's performance for the period from September 1, 2025, to February 28, 2026 was 13.20% based on net asset value.

**Past performance is not predictive of future results.** Performance calculations do not reflect any deduction of taxes that a shareholder may have to pay on Fund distributions or any commissions payable on the sale of Fund shares.

The following table provides summary data on the Fund's dividends based on NAV as of February 28, 2026:

---

| | |
|:---|:---|
|  Dividend yield based on NAV | 1.47% |
|  NAV as of February 28, 2026 | $3.40 |

---

The Fund seeks to pay monthly dividends out of its net investment income. To allow the Fund to maintain a more stable monthly dividend, the Fund may pay dividends that are more or less than the amount of net income earned during the period. All of the fund's dividend distribution of $551,340 consisted of the fund's net investment income for the period. The basis of the distributions is the Fund's net investment income for tax purposes.

The table below reflects the breakdown of the Fund's investment portfolio as of February 28, 2026. For details of the security categories below, please refer to the enclosed Schedule of Investments.

| | |
|:---|:---|
| **Asset allocation (% of Total Portfolio)** | |
|  Municipal Bonds | 58.2% |
|  Government Bonds | 40.9% |
|  Mortgage-backed Securities | 0.9% |

---

The largest Puerto Rico municipal bond holdings in the portfolio, representing 45.9%, are the new issue Puerto Rico Sales Tax Financing Corporation ("COFINA") bonds. The newly exchanged bonds are secured by 45.9% of the pledged sales and use tax through 2058, which amounts to $552.9 million for period ended 2026 and a 4% increase each period, capping out at $992.5 million for the period ended 2041. The valuation of the COFINA bonds decreased during the period. Transfers to the trustee for the redemption of the bonds for period 2025 commenced on July 1, 2025. As of October 2025, 100% of the required deposits had been transferred to the Trustee.

The Fund owns several mortgage-backed securities ("MBS") representing 0.9% of its portfolio. They include MBS issued and guaranteed by U.S. agencies, 0.8%, and certain Puerto Rico tax-exempt notes collateralized with U.S. agency MBS 0.1%. The balance of the MBS decreased from the repayment of the underlying mortgages.

The Fund's U.S. holdings are comprised of U.S. agencies and U.S. municipal bonds representing 40.9% and 9.1%, respectively of the portfolio. The valuation of the U.S. agencies and municipal bonds decreased during the period in response to higher interest rates.

The Fund's NAV increased $0.35 during the period from $3.05 at the beginning of the period to $3.40 at period-end. As discussed above, there was an increase in the valuation of the Fund's portfolio.

**FUND HOLDINGS SUMMARY**

**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. These asset coverage requirements 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. 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 levels. 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 levels. In such instances, the Fund will redeem Senior Securities, as needed, to maintain the required asset coverage.

Subject to the above percentage limitations, the Fund may also engage in certain additional borrowings from banks or other financial institutions through reverse repurchase agreements. 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 may enter into collateralized reverse repurchase agreements with major institutions in the U.S. and/or may issue TSOs in the Puerto Rico market. Both, if applicable, are accounted for as collateralized borrowings in the financial statements. Typically, the Fund borrows for approximately 30-90 days at a variable borrowing rate based on short-term rates. The TSO program was suspended in May 2021 pending registration under the 1933 Act.

As of February 28, 2026, the Fund had the following leverage outstanding:

---

| | |
|:---|:---|
|  Reverse Repurchase Agreements | 12779000 |
|  Leverage Ratio<sup>1</sup>  | 25.31% |

---

Please refer to the Schedule of Investments for details of the securities pledged as collateral and to Note 6 to the Financial Statements for further details on outstanding leverage during the period. Fund leverage decreased by $1,121,000 during the period ended February 28, 2026.

***<sup>1</sup>*** ***Asset Leverage ratio*:** *The sum of (i) the aggregate principal amount of outstanding TSOs plus (ii) 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-4 going 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.*

The Fund's investment objective is to achieve a high level of current income that, for Puerto Rico residents, is exempt from federal and Puerto Rico income taxes, consistent with the preservation of capital. There is no assurance that the Fund will achieve its investment objective.

On May 24, 2018, the Economic Growth, Regulatory Relief, and Consumer Protection Act (Pub. L. No. 115-174) was signed into law and amended the 1940 Act to repeal the exemption from its registration of investment companies created under the laws of Puerto Rico, the U.S. Virgin Islands, or any other U.S. possession under Section 6(a)(1) thereof. The repeal of the exemption took effect on May 24, 2021. Upon registration under the 1940 Act, the Fund must now register its future offering of securities under the 1933 Act, absent an available exception. There is limited trading in Fund shares, which are not registered under the 1933 Act, and are only traded via private transactions. The Fund has suspended the issuance of TSOs pending registration under the 1933 Act.

The Fund is an investment company that applies the accounting and reporting guidance 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.

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements:

*(a)* *Cash and Cash Equivalents* – Cash and cash equivalents consist of demand deposits and funds invested in
short-term investments with original **  maturities of 90 days or less. Cash and cash equivalents are valued at amortized cost, which approximates fair value. At February 28, 2026, cash and cash equivalents consisted of a time deposit open
account amounting to $355,721 with State Street Bank & Trust Company.

*(b)* *Valuation of Investments* – Investments included in the Fund's financial statements have been
stated at fair value as determined by the Fund, with **  the assistance of the Investment Adviser (refer to Note 3 for details on the investment advisory agreement), on the basis of valuations provided by dealers or by pricing services which are
approved by Fund management and the Fund's Board of Directors (the "Board") in accordance with the valuation methods set forth in the governing documents and related policies and procedures. The Investment Adviser has

---

been appointed by the Fund's Board as the valuation designee pursuant to Rule 2a-5 of the 1940 Act. See Note 2 for further discussions regarding fair value disclosures.

*(c)* *Taxation* – The Fund has elected to be treated as a registered investment company under the Puerto Rico
Internal Revenue Code of 2011, as **  amended, and the regulations and administrative pronouncements promulgated thereunder. As a registered investment company under the 1940 Act, the Fund will not be subject to Puerto Rico income tax for any
taxable period if it distributes at least 90% of its taxable net investment income for such period, as determined for these purposes pursuant to the provisions of 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 has never been subject to taxation.

In addition, the fixed income and equity investments of the Fund are exempt from Puerto Rico personal property taxes. The Fund does not intend to qualify as a Regulated Investment Company ("RIC") under Subchapter M of the U.S. Internal Revenue Code of 1986, as amended, 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 typical U.S. mutual funds (such as RIC tax treatment, i.e., availability of pass-through tax status for non-Puerto Rico residents) and may have adverse tax consequences for U.S. federal income tax purposes. The Fund is exempt from United States income taxes, except for dividends received from United States sources, which are subject to a 10% United States withholding tax if certain requirements are met. In the opinion of the Fund's legal counsel, the Fund is not required to file a U.S. federal income tax return.

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 return 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 expense in the current period. Management has analyzed the Fund's tax positions taken on its Puerto Rico income tax returns for all open tax periods (the current and prior three tax periods) 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 period ended February 28, 2026, the Fund did not incur any interest or penalties.

*(d)* *Statement of Cash Flows* – The Fund invests in securities and distributes dividends from net investment
income, which are paid in cash or are **  reinvested at the discretion of common shareholders. 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.

---

*(e)* *Dividends and Distributions to Shareholders* – Dividends from substantially all of the Fund's net
investment income are declared and paid monthly. **  The Fund may at times pay out more or less than the entire amount of net investment income earned in any particular period and may at times pay out such accumulated undistributed income earned
in other periods in order to permit the Fund a more stable level of distribution. The Fund records dividends to its shareholders on the ex-dividend date. The Fund does not expect to make distributions of net
realized capital gains, although the Fund's Board reserves the right to do so in its sole discretion.

*(f)* *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 ownership of the collateral through the agreement that requires the repurchase and return of such collateral. 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 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 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 (See Note 6).

*(g)* *Short- and Medium-term Notes –* The Fund has a short- and medium-term notes payable program as a
funding vehicle to increase the amount **  available for investment. The short- and medium-term notes are issued from time to time in denominations of at least $1,000 and maturing in periods of up to 270 days and over 270 days, respectively. The
notes are collateralized by the pledge of certain securities of the Fund. The pledged securities are held by State Street Bank & Trust Co. (the "Custodian"), as collateral agent, for the benefit of the holders of the notes.
Selling fees related to the issuance of medium-term notes are amortized throughout the term of the note or until its first call date. There were no short- or medium-term notes outstanding for the period from September 1, 2025, to
February 28, 2026.

*(h)* *Restructuring Expenses* – Legal expenses incurred by the Fund related to Puerto Rico bond
restructurings have been accounted for as a realized loss. **

*(i)* *Operating Segments –* 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-determined in 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, 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 Statement. 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.

*(i)* *Other* – Security transactions are accounted for on the trade date (the date the order to buy or sell
is executed). Realized gains and losses on security **  transactions are determined based on the identified cost method. Premiums and discounts on securities purchased are amortized over the life or the expected life of the respective securities
using the effective interest method. Interest income on preferred equity securities is accrued daily except when collection is not expected. Dividend income on preferred equity securities is recorded on the ex-dividend date.

**NOTE 2. FAIR VALUE MEASUREMENTS** 

Under GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability.

GAAP establishes a fair value hierarchy that prioritizes the inputs and valuation techniques used to measure fair value into three levels in order to increase consistency and comparability in fair value measurements and disclosures. The classification of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for the fair value measurement are observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs reflect the Fund's estimates about assumptions that market participants would

---

use in pricing the asset or liability based on the best information available. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

---

| | |
|:---|:---|
| **Level 1 –** | Unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. Valuation on these instruments does not need a significant degree of judgment since valuations are based on quoted prices that are readily available in an active market. |
| **Level 2 –** | Quoted prices other than those included in Level 1 that are observable either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active or other inputs that are observable or that can be corroborated by observable market data for substantially the full term of the financial instrument. |
| **Level 3 –** | Unobservable inputs are significant to the fair value measurement. Unobservable inputs reflect the Fund's own assumptions about assumptions that market participants would use in pricing the asset or liability. |

---

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. The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Fair value is based upon quoted market prices when available. If listed prices or quotes are not available, the Fund employs internally developed models that primarily use market-based inputs including yield curves, interest rates, volatilities, and credit curves, among others. 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 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. In addition, the fair value estimates are based on outstanding balances without attempting to estimate the value of anticipated future business. Therefore, the estimated fair value may materially differ from the value that could actually be realized in a sale. The Fund monitors the portfolio securities to ensure they are in the correct hierarchy level.

The Board has designated the Investment Adviser as the valuation designee pursuant to Rule 2a-5 under the 1940 Act and delegated to the Investment Adviser the responsibility for making fair value determinations with respect to portfolio holdings. The Investment Advisor has delegated to the Valuation Committee, comprised of voting members of the Investment Adviser, certain procedures and functions related to the valuation of portfolio securities for the purpose of determining the NAV of the Fund. The Valuation Committee is generally responsible for determining the fair value of the following types of portfolio securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Portfolio instruments for which no price or value is available at the time the Fund's NAV is calculated on a
particular day;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Portfolio instruments for which the prices or values available do not, in the judgment of the Investment Adviser,
represent the fair value of the portfolio instruments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A price of a portfolio instrument that has not changed for four consecutive weekly pricing periods, except for Puerto
Rico taxable securities and U.S. portfolio instruments; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Puerto Rico taxable securities and the U.S. portfolio instruments whose value has not changed from the previous
weekly pricing period.

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

**Mortgage and other asset-backed securities:** Certain agency mortgage and other assets-backed securities ("MBS") are priced based on a bond's theoretical value derived from the prices of similar bonds; "similar" being defined by credit quality and market sector. Their fair value incorporates an option adjusted spread. The agency MBS and GNMA Puerto Rico Serials are classified as Level 2.

**Obligations of Puerto Rico and political subdivisions:** Obligations of Puerto Rico and political subdivisions are segregated, and the like characteristics divided into specific sectors. Market inputs used in the evaluation process include all or some of the following: trades, bid price or spread, quotes, benchmark curves including but not limited to Treasury benchmarks, LIBOR and swap curves and discount and capital rates. These bonds are classified as Level 2. During the current period, the Puerto Rico Industrial Tourist Educational Medical & Environmental Control Facilities Financing Authority ("AFICA") bonds were classified as Level 3. Management determined that a discounted cash flow approach was the appropriate valuation technique, with fair value primarily based on the present value of the expected bankruptcy settlement cash flows to bondholders at a 10% rate.

**Puerto Rico Tax Exempt Notes:** Prices for these securities are obtained from broker quotes. These securities trade in over-the-counter markets. Quoted prices are based on recent trading activity for similar instruments and do not trade in highly liquid markets. Community endowments are generally classified as Level 2 and the pricing is based on their collateral.

**Obligations of U.S. government sponsored entities and state and municipal obligations:** The fair value of obligations of U.S. government sponsored entities and state and 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. U.S. agency structured notes are priced based on a bond's theoretical value from similar bonds defined by credit quality and market sector, and for which the fair value incorporates an option adjusted spread in deriving their fair value. These securities are classified as Level 2.

The following is a summary of the levels within the fair value hierarchy in which the Fund invests based on inputs used to determine the fair value of such securities:

Temporary cash investments, if any, are valued at amortized cost, which approximates fair value. As of period-end there were no temporary cash investments.

**NOTE 3. INVESTMENT ADVISORY, ADMINISTRATIVE, CUSTODY, AND TRANSFER AGENCY ARRANGEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES** 

Pursuant to an investment advisory agreement with the Investment Adviser, the Fund receives advisory services in exchange for a fee. The investment advisory fee is calculated at an annual rate of 0.375% of the Fund's average weekly gross assets, including the liquidation value of all outstanding debt securities of the Fund, as defined in the investment advisory agreement. For the period ended February 28, 2026, the gross investment advisory fees amounted to $91,871. Total voluntarily waived fees amounted to $30,624 for a net fee of $61,247, of which $9,574 remains payable at period-end. There will be no recoupment of these voluntarily waived fees.

State Street Bank & Trust Company, together with certain affiliated entities, has been retained to serve as the Fund's administrator and provides various administration, fund accounting, and investor accounting services to the Fund. Banco Popular de Puerto Rico serves as transfer agent, registrar, dividend disbursing agent, and shareholder servicing agent to the Fund. For the period ended February 28, 2026, the administrative fees and transfer agent fees amounted to $44,276 and $5,951, respectively, of which $58,889 and $6,951, respectively, remains payable at period-end.

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 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.

|  Weighted average interest rate at end of the period | 3.88% |
|  Maximum aggregate balance outstanding at any time during the period | $14130000 |
|  Average balance outstanding during the period | $13794862 |
|  Average interest rate during the period | 4.18% |

---

At February 28, 2026, interest rate on reverse repurchase agreements was 3.88% and the maturity was March 19, 2026. The interest rates on collateral were 5.50% and 6.625% and the maturity date was from November 15, 2030, to July 15, 2036. The outstanding agreements to repurchase as of period-end may be called by the counterparty before their maturity dates.

At February 28, 2026, investment securities with fair values amounting to $14,159,424 are pledged as collateral for reverse repurchase agreements. The counterparties have the right to sell or repledge the assets during the term of the reverse repurchase agreement with the Fund. Interest payable on reverse repurchase agreements amounted to $23,414 at February 28, 2026.

At February 28, 2026, the total value of reverse repurchase agreements were as follows:

*(a)* *Collateral received or posted is limited to the net securities sold under reverse repurchase agreements liability amounts. See above for actual collateral received and posted.* 

**NOTE 7. SHORT-TERM AND LONG-TERM FINANCIAL INSTRUMENTS** 

The fair market value of short-term financial instruments, which include $12,779,000 in reverse repurchase agreements, are substantially the same as the carrying amounts reflected in the Statement of Assets and Liabilities as these are reasonable estimates of fair value, given the relatively short period of time between origination of the instrument and their expected realization. Securities sold under agreements to repurchase are classified as Level 2 securities under the fair value hierarchy. There are no long-term financial debt instruments outstanding at February 28, 2026.

**NOTE 8. CONCENTRATION OF CREDIT RISK** 

Concentrations of credit risk (whether on or off-balance sheet) that arise from financial instruments exist 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. For this purpose, management has determined to disclose any investment whose fair value is over 5% of net assets, both individually and in the aggregate. Moreover, collateralized investments have been excluded from this disclosure.

The major concentration of credit risk arises from the Fund's investment securities in relation to the location of issuers. For calculation of concentration, all fixed-income securities guaranteed by the U.S. government are excluded. At February 28, 2026, the Fund had investments with an aggregate market value of $24,378,054 which were issued by entities located in Puerto Rico and are not guaranteed by the U.S. government nor the Puerto Rico government. Also, at February 28, 2026, the Fund had an investment with a market value of $4,518,471, which was issued by one issuer located in the United States and is not guaranteed by the U.S. government.

Under normal circumstances the Fund invests, as market conditions permit, at least 67% of its total assets in Puerto Rico obligations ("the 67% Investment Requirement"). Therefore, to the extent the securities are not guaranteed by the U.S. government or any of its subdivisions, the Fund is more susceptible to factors adversely affecting issuers of Puerto Rico obligations than an investment company that is not concentrated in Puerto Rico obligations to such degree.

**NOTE 9. 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 statutorily or by regulation while others are by procedures established by the Board. The most significant requirements and limitations are discussed below.

The Fund invests under normal circumstances at least 67% of its total assets, including borrowings for investment purposes, in securities issued by Puerto Rico entities. A "Puerto Rico entity" or a "Puerto Rico security" is any entity or security that satisfies one or more of the following criteria: (i) securities of issuers that are organized under the laws of Puerto Rico or that maintain their principal place of business in Puerto Rico; (ii) securities that are traded principally in Puerto Rico; or (iii) securities of issuers that, during the issuer's most recent period, derived at least 20% of their revenues or profits from goods produced or sold, investments made, or services performed in Puerto Rico or that have at least 20% of their assets in Puerto Rico. While the Fund intends to comply with the above 67% Investment Requirement as market conditions permit, the Fund's ability to procure sufficient Puerto Rico securities which meet the Fund's investment criteria may be constrained due to the volatility affecting the Puerto Rico bond market since 2013 and the fact that the Puerto Rico government is currently in the process of restructuring its outstanding debt under Title III of the Puerto Rico Oversight, Management, and Economic Stability Act. To the extent that the Fund is unable to procure sufficient amounts of such Puerto Rico securities, the Fund may acquire investments in securities of non-Puerto Rico issuers which satisfy the Fund's investment

criteria, provided its ability to comply with its tax-exempt policy is not affected, but the Fund will ensure that its investments in Puerto Rico securities will constitute at least 20% of its assets.

The Fund invests, except where the Fund is unable to procure sufficient Puerto Rico Securities that meet the Fund's investment criteria, in the opinion of the Investment Adviser, or other extraordinary circumstances, up to 33% of its total assets in securities issued by non-Puerto Rico entities. These include securities issued or guaranteed by the U.S. government, its agencies and instrumentalities, non-Puerto Rico mortgage-backed and asset-backed securities, corporate obligations and preferred stock of non-Puerto Rico entities, municipal securities of issuers within the U.S., and other non-Puerto Rico securities that the Investment Adviser may select, consistent with the Fund's investment objectives and policies.

The Fund may increase amounts available for investment through the issuance of preferred stock, debt securities, or other forms of leverage ("Senior Securities"). The Fund may only issue 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 levels. 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 levels. In such instances, the Fund will redeem Senior Securities as needed to maintain the required asset coverage.

The Fund, subject to the above percentage limitations, may also engage in certain additional borrowings from banks or other financial institutions through reverse repurchase agreements. 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.

|  Gross depreciation | (3189532) |
|  Net appreciation/(depreciation) | $(1986974) |

**NOTE 11. INDEMNIFICATIONS** 

In the normal course of business, the Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these agreements is unknown. However, the Fund has not paid prior claims or losses pursuant to these contracts and expects the risk of losses to be remote.

**NOTE 12. 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, and pandemic or other public health threats, among others. This list is qualified by reference to the more detailed information provided in the prospectus for the securities issued by the Fund.

The Fund's assets are invested primarily in securities of Puerto Rico issuers. As a result, the Fund has greater exposure to adverse economic, political, or regulatory changes in Puerto Rico than a more geographically diversified fund, particularly with regard to municipal bonds issued by the Commonwealth of Puerto Rico and its related instrumentalities, which are currently experiencing significant price volatility and low liquidity. Also, the Fund's NAV and its yield may increase or decrease more than that of a more diversified investment company as a result of changes in the market's assessment of the financial condition and prospects of such Puerto Rico issuers.

Interest rate risk is the risk that interest rates will rise so that the value of existing fixed rate securities will fall. Low long-term rates present the risk that interest rates may rise and that as a result the Fund's investments will decline in value. Also, the Fund's yield will tend to lag behind changes in prevailing short-term interest rates. In addition, 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), and reduce the value of the security. This is known as extension risk, which the Fund is also subject

to. Conversely, during periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled in order to refinance at lower interest rates, forcing the Fund to reinvest in lower yielding securities. This is known as prepayment risk, which the Fund is also subject to.

Credit risk is the risk that debt securities in the Fund's portfolio 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. The risk is greater in the case of securities rated below investment grade or rated in the lowest investment grade category.

The Fund may engage in reverse repurchase agreements, which are transactions in which the Fund sells a security to a counterparty and agrees to buy it back at a specified time and price in a specified currency. Reverse repurchase agreements involve the risk that the buyer of the securities sold by the Fund might be unable to deliver the securities when the Fund seeks to repurchase them and may be unable to replace the securities or only at a higher cost.

Mortgage-backed securities in which the Fund may invest 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. Since a substantial portion of the assets of the Fund may be invested in mortgage-backed securities at any time, the Fund may be subject to these risks and other risks related to such securities to a significant degree, which might cause the market value of the Fund's investments to fluctuate more than otherwise would be the case. Collateralized mortgage obligations ("CMOs") exhibit similar risks to those of mortgage-backed securities but also present certain special risks. 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. These changes may result in volatility in the market value, and in some instances, reduced liquidity of the CMO class.

The Fund may also invest in illiquid securities which are securities that cannot be sold within a reasonable period of time, not to exceed seven days, in the ordinary course of business at approximately the amount at which the Fund has valued the securities. 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. Illiquid securities may trade at a discount from comparable, more liquid investments.

There may be few or no dealers making a market in certain securities owned by the Fund, particularly with respect to securities of Puerto Rico issuers including, but not limited to, investment companies. Dealers making a market in those securities may not be willing to provide quotations on a regular basis to the Investment Adviser. It may, therefore, be particularly difficult to value those securities.

In order to attempt to hedge various portfolio positions or to enhance its return, the Fund may invest a portion of its total assets in certain instruments which are or may be considered derivatives. Because of their increased volatility and potential leveraging effect (without being subject to the Fund's leverage limitations), derivative instruments may adversely affect the Fund. For example, investments in indexed securities, including, among other things, securities linked to an equities or commodities index and inverse floating rate securities, may subject the Fund to the risks associated with changes in the particular indices, which may include reduced or eliminated interest payments and losses of invested principal. Such investments, in effect, may also be leveraged, thereby magnifying the risk of loss

**NOTE 13. SUBSEQUENT EVENTS** 

On March 31, 2026, the Board of Directors declared an ordinary net investment income dividend of $0.00833, per common share, totaling $91,911, which was paid on April 10, 2026, to common shareholders of record as of March 31, 2026.

The Fund has performed an evaluation of events occurring subsequent to February 28, 2026, through April 27, 2026, which is the date the semi-annual financial statements were available to be issued. Management has determined that there were no events that occurred during this period that required disclosure in, or adjustment to, the accompanying financial statements other than those disclosed above.
