Semi-Annual Report
December 31, 2025
Commodity Futures Trading Commission Registration. The Commodity Futures Trading Commission (“CFTC”) has adopted regulations that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a
prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The investment adviser has claimed an exclusion
from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of the Fund. Accordingly, neither the Fund nor the adviser with respect to the operation of the Fund is subject to CFTC
regulation. Because of its management of other strategies, the Fund's adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.
Fund shares are not insured by the FDIC and are not deposits or
other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

Past performance is no guarantee of future results.
Returns are historical and are calculated net of management fees and other expenses by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested in accordance with the Fund’s
Dividend Reinvestment Plan. Furthermore, returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares. Performance at market price will differ from performance at NAV due to
variations in the Fund’s market price versus NAV, which may reflect factors such as fluctuations in supply and demand for Fund shares, changes in Fund distributions, shifting market expectations for the Fund’s future returns and
distribution rates, and other considerations affecting the trading prices of closed-end funds. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance for
periods less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return. For performance as of the most recent month-end,

Fund Profile
| Credit Quality (% of bonds, loans and asset-backed securities)2 |
Footnotes:
| 1 | Excludes cash and cash equivalents. |
| 2 | Credit ratings are categorized using S&P Global Ratings (“S&P”). Ratings, which are subject to change, apply to the creditworthiness of the issuers of the underlying securities and not to the Fund or its shares. Credit ratings measure the quality of a bond based on the issuer’s creditworthiness, with ratings ranging from AAA, being the highest, to D, being the lowest based on S&P’s measures. Ratings of BBB or higher by S&P are considered to be investment-grade quality. Credit ratings are based largely on the ratings agency’s analysis at the time of rating. The rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition and does not necessarily reflect its assessment of the volatility of a security’s market value or of the liquidity of an investment in the security. Holdings designated as “Not Rated” (if any) are not rated by S&P. |

business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, closed-end management investment company. The Trust’s investment objective is to provide a high level of current income,
consistent with the preservation of capital, by investing primarily in senior, secured floating-rate loans.
The following is a summary of significant accounting policies
of the Trust. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Trust is an investment company and follows accounting and reporting guidance in the Financial Accounting
Standards Board (FASB) Accounting Standards Codification Topic 946.
A Investment
Valuation—The following methodologies are used to determine the market value or fair value of
investments.
Senior Floating-Rate Loans. Interests in senior floating-rate loans (Senior Loans) are valued generally at the average mean of bid and ask quotations obtained from a third party pricing service. Senior Loans, for which a valuation is not available
or deemed unreliable, are fair valued by the investment adviser utilizing one or more of the valuation techniques described below to assess the likelihood that the borrower will make a full repayment of the loan underlying such Senior Loan. If the
investment adviser believes that there is a reasonable likelihood of full repayment, the investment adviser will determine fair value using a matrix pricing approach that considers the yield on the Senior Loan relative to yields on other Senior
Loans issued by companies of comparable credit quality. If the investment adviser believes there is not a reasonable likelihood of full repayment, the investment adviser will determine fair value using analyses that include, but are not limited to:
(i) a comparison of the value of the borrower’s outstanding equity and debt to that of comparable public companies; (ii) a discounted cash flow analysis; or (iii) when the investment adviser believes it is likely that a borrower will be
liquidated or sold, an analysis of the terms of such liquidation or sale. In certain cases, the investment adviser will use a combination of analytical methods to determine fair value, such as when only a portion of a borrower’s assets are
likely to be sold. In conducting its assessment and analyses for purposes of determining fair value of a Senior Loan, the investment adviser will use its discretion and judgment in considering and appraising relevant factors. Junior Loans (i.e.,
subordinated loans and second lien loans) are valued in the same manner as Senior Loans.
Debt Obligations. Debt
obligations are generally valued on the basis of valuations provided by third party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and
ask prices, broker/dealer quotations, prices or yields of securities with similar characteristics, interest rates, anticipated prepayments, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The
pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Short-term debt obligations purchased with a remaining maturity of sixty days or
less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value.
Equity Securities. Equity
securities listed on a U.S. securities exchange generally are valued at the last sale or closing price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and ask prices on the exchange where such
securities are principally traded. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available
are valued at the mean between the latest available bid and ask prices or, in the case of preferred equity securities that are not listed or traded in the over-the-counter market, by a third party pricing service that uses various techniques that
consider factors including, but not limited to, prices or yields of securities with similar characteristics, benchmark yields, broker/dealer quotes, quotes of underlying common stock, issuer spreads, as well as industry and economic
events.
Derivatives. Forward foreign currency exchange contracts are generally valued at the mean of the average bid and average ask prices that are reported by currency dealers to a third party pricing service at the valuation time. Such
third party pricing service valuations are supplied for specific settlement periods and the Trust’s forward foreign currency exchange contracts are valued at an interpolated rate between the closest preceding and subsequent settlement period
reported by the third party pricing service.
Foreign
Securities and Currencies. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rate quotations supplied by a third party pricing service. The pricing service uses a
proprietary model to determine the exchange rate. Inputs to the model include reported trades and implied bid/ask spreads.
Other. Investments in
management investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value as of the close of each business day.
Fair Valuation. In connection
with Rule 2a-5 of the 1940 Act, the Trustees have designated the Trust’s investment adviser as its valuation designee. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued by the
investment adviser, as valuation designee, at fair value using methods that most fairly reflect the security’s “fair value”, which is the amount that the Trust might reasonably expect to receive for the security upon its current
sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the
existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from
broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an
evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B Investment Transactions—Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized
gains and losses on investments sold are determined on the basis of identified cost.
C Income—Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Fees in connection
with investments in senior floating-rate loans may include amendment fees, consent fees and prepayment fees, which are recorded to income as earned and included in Other income on the Statement of Operations. Dividend income is recorded on the
ex-dividend date for dividends received in cash and/or securities. Distributions from investment companies are recorded as dividend income, capital gains or return of capital based on the nature of the distribution.
D Federal and Other Taxes—The Trust's policy is to comply with the provisions of the Internal Revenue Code applicable to regulated
investment companies and to distribute to shareholders each year substantially all of its net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is
necessary. As of December 31, 2025, the Trust had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Trust files a U.S. federal income tax return
annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.
E Foreign Currency Translation—Investment valuations, other assets, and liabilities initially expressed in foreign currencies are
translated each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency
exchange rates in effect on the respective dates of such transactions. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized
gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.
F Unfunded Loan Commitments—The Trust may enter into certain loan agreements all or a portion of which may be unfunded. The Trust is
obligated to fund these commitments at the borrower's discretion. These commitments, if any, are disclosed in the accompanying Portfolio of Investments. At December 31, 2025, the Trust had sufficient cash and/or securities to cover these
commitments.
G Use of Estimates—The preparation of the financial statements in conformity with U.S. GAAP requires management to make
estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those
estimates.
H Indemnifications—Under the Trust’s organizational documents, its officers and Trustees may be indemnified against
certain liabilities and expenses arising out of the performance of their duties to the Trust. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Trust) could be deemed to have personal
liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Trust shareholders and the By-laws provide that the Trust shall assume, upon request by the
shareholder, the defense on behalf of any Trust shareholders. Moreover, the By-laws also provide for indemnification out of Trust property of any shareholder held personally liable solely by reason of being or having been a shareholder for all loss
or expense arising from such liability. Additionally, in the normal course of business, the Trust enters into agreements with service providers that may contain indemnification clauses. The Trust's maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the Trust that have not yet occurred.
I Forward Foreign Currency Exchange Contracts—The Trust may enter into forward foreign currency exchange contracts for the purchase or sale of a
specific foreign currency at a fixed price on a future date. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until such time as the
contracts have been closed. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from movements in the value of a foreign currency relative to the U.S.
dollar.
J Segment Reporting—The Trust operates as a single reportable segment, an investment company whose investment objective(s) is
included in Note 1. The Trust’s President acts as the Trust's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of the Trust's single segment and deciding how to allocate the segment’s
resources. To perform this function, the CODM reviews the information in the Trust’s financial statements.
K Interim Financial Statements—The interim financial statements relating to December 31, 2025 and for the six months then ended have not
been audited by an independent registered public accounting firm, but in the opinion of the Trust’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial
statements.

2 Auction Preferred Shares
The Trust issued Auction Preferred Shares (APS) on July 27,
2001 in a public offering. Dividends on the APS, which accrue daily, are cumulative at rates which are reset every seven days by an auction, unless a special dividend period has been set. Series of APS are identical in all respects except for the
reset dates of the dividend rates. If the APS auctions do not successfully clear, the dividend payment rate over the next period for the APS holders is set at a specified maximum applicable rate until such time as the APS auctions are successful.
Auctions have not cleared since February 13, 2008 and the rate since that date has been the maximum applicable rate (see Note 3). The maximum applicable rate on the APS is 125% of the “AA” Financial Composite Commercial Paper Rate at the
date of the auction. The stated spread over the reference benchmark rate is determined based on the credit rating of the APS.
The number of APS issued and outstanding as of December 31,
2025 are as follows:
| APS
Issued and Outstanding | |
| Series A | 752 |
| Series B | 752 |
The APS are redeemable at the option
of the Trust at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, on any dividend payment date. The APS are also subject to mandatory redemption at a redemption price equal to $25,000 per share, plus accumulated
and unpaid dividends, if the Trust is in default for an extended period on its asset maintenance requirements with respect to the APS. If the dividends on the APS remain unpaid in an amount equal to two full years’ dividends, the holders of
the APS as a class have the right to elect a majority of the Board of Trustees. In general, the holders of the APS and the common shares have equal voting rights of one vote per share, except that the holders of the APS, as a separate class, have
the right to elect at least two members of the Board of Trustees. The APS have a liquidation preference of $25,000 per share, plus accumulated and unpaid dividends. The Trust is required to maintain certain asset coverage with respect to the APS as
defined in the Trust's By-Laws and the 1940 Act. The Trust pays an annual fee up to 0.15% of the liquidation value of the APS to broker/dealers as a service fee if the auctions are unsuccessful; otherwise, the annual fee is 0.25%.
3 Distributions to Shareholders and Income Tax
Information
The Trust intends to make monthly
distributions of net investment income to common shareholders, after payment of any dividends on any outstanding APS. In addition, at least annually, the Trust intends to distribute all or substantially all of its net realized capital gains.
Distributions to common shareholders are recorded on the ex-dividend date. Distributions to preferred shareholders are recorded daily and are payable at the end of each dividend period. The dividend rates for the APS at December 31, 2025, and the
amount of dividends accrued (including capital gains, if any) to APS shareholders, average APS dividend rates (annualized), and dividend rate ranges for the six months then ended were as follows:
| APS
Dividend Rates at December 31, 2025 |
Dividends
Accrued to APS Shareholders |
Average
APS Dividend Rates |
Dividend
Rate Ranges (%) | |
| Series A | 4.57% | $495,752 | 5.16% | 4.54-5.46 |
| Series B | 4.57 | 494,752 | 5.15 | 4.54-5.46 |
Beginning February 13, 2008 and
consistent with the patterns in the broader market for auction-rate securities, the Trust's APS auctions were unsuccessful in clearing due to an imbalance of sell orders over bids to buy the APS. As a result, the dividend rates of the APS were reset
to the maximum applicable rates. The table above reflects such maximum dividend rate for each series as of December 31, 2025.
Distributions to shareholders are determined in accordance with
income tax regulations, which may differ from U.S. GAAP. As required by U.S. GAAP, only distributions in excess of tax basis earnings and profits are reported in the financial statements as a return of capital. Permanent differences between book and
tax accounting relating to distributions are reclassified to paid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income. For the six months ended December 31, 2025, the amount of
distributions estimated to be a tax return of capital was approximately $222,000. The final determination of tax characteristics of the Trust’s distributions will occur at the end of the year, at which time it will be reported to the
shareholders.
At June 30, 2025, the Trust, for federal
income tax purposes, had deferred capital losses of $29,472,699 which would reduce its taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus would
reduce the amount

Eaton Vance
Senior Income Trust
December 31, 2025
Notes to Financial
Statements (Unaudited) — continued
of distributions to
shareholders, which would otherwise be necessary to relieve the Trust of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Trust’s next taxable year and retain the same
short-term or long-term character as when originally deferred. Of the deferred capital losses at June 30, 2025, $1,070,393 are short-term and $28,402,306 are long-term.
The cost and unrealized appreciation (depreciation) of
investments, including open derivative contracts, of the Trust at December 31, 2025, as determined on a federal income tax basis, were as follows:
| Aggregate cost | $165,494,144 |
| Gross unrealized appreciation | $ 1,987,167 |
| Gross unrealized depreciation | (7,073,567) |
| Net unrealized depreciation | $ (5,086,400) |
4 Investment Adviser Fee and Other Transactions
with Affiliates
The investment adviser fee is earned by
Eaton Vance Management (EVM), an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory services rendered to the Trust. The investment adviser fee is computed at an annual rate of 0.69% of the Trust’s
average weekly gross assets and is payable monthly. The annual investment adviser fee rate shall be reduced to the following as of the stated date: May 1, 2026: 0.55%. Gross assets as referred to herein are calculated by deducting accrued
liabilities of the Trust except the principal amount of any indebtedness for money borrowed, including debt securities issued by the Trust. For the six months ended December 31, 2025, the Trust’s investment adviser fee amounted to
$570,541.
The Trust may invest in a money market fund,
the Institutional Class of the Morgan Stanley Institutional Liquidity Funds - Government Portfolio (the “Liquidity Fund”), an open-end management investment company managed by Morgan Stanley Investment Management Inc., a wholly-owned
subsidiary of Morgan Stanley. The investment adviser fee paid by the Trust is reduced by an amount equal to its pro rata share of the advisory and administration fees paid by the Trust due to its investment in the Liquidity Fund. For the six months
ended December 31, 2025, the investment adviser fee paid was reduced by $2,278 relating to the Trust’s investment in the Liquidity Fund. The administration fee is earned by EVM for administering the business affairs of the Trust and is
computed at an annual rate of 0.25% of the Trust’s average weekly gross assets. For the six months ended December 31, 2025, the administration fee amounted to $206,718.
Trustees and officers of the Trust who are members of
EVM’s organization receive remuneration for their services to the Trust out of the investment adviser fee. Trustees of the Trust who are not affiliated with EVM may elect to defer receipt of all or a percentage of their annual fees in
accordance with the terms of the Trustees Deferred Compensation Plan. Certain officers and Trustees of the Trust are officers of EVM.
5 Purchases and Sales of Investments
Purchases and sales of investments, other than short-term
obligations and including maturities, paydowns and principal repayments on Senior Loans, aggregated $35,800,662 and $39,379,074, respectively, for the six months ended December 31, 2025.
6 Common Shares of Beneficial Interest and Shelf
Offering
The Trust may issue common shares pursuant to
its dividend reinvestment plan. There were no common shares issued by the Trust for the six months ended December 31, 2025. Common shares issued by the Trust pursuant to its dividend reinvestment plan were 22,018 for the year ended June 30,
2025.
On May 12, 2021, the Trust announced that it will
conduct cash tender offers in the fourth calendar quarter of each of 2022, 2023 and 2024 (each, a “Conditional Tender Offer”) for up to 10% of the Trust’s then-outstanding common shares if, from January to August of the relevant
year, the Trust’s shares trade at an average daily discount to NAV of more than 10%, based upon the Trust’s volume-weighted average market price and NAV on each business day during the period. If triggered, common shares tendered and
accepted in a Conditional Tender Offer would be repurchased at a price per share equal to 98% of the Trust’s NAV as of the close of regular trading on the New York Stock Exchange on the date such Conditional Tender Offer expires. The condition
to trigger a tender offer by the Trust in the fourth calendar quarter of 2024 was not met.
In November 2013, the Board of Trustees initially approved a
share repurchase program for the Trust. Pursuant to the reauthorization of the share repurchase program by the Board of Trustees in March 2019, the Trust is authorized to repurchase up to 10% of its common shares outstanding as of the last day
of the prior calendar year at market prices when shares are trading at a discount to net asset value. The share repurchase program does not obligate the Trust to purchase a specific amount of shares. There were no repurchases of common shares by the
Trust pursuant to the share repurchase program for the six months ended December 31, 2025 and the year ended June 30, 2025.

In
August 2022, the Trust filed an automatically effective shelf registration statement (the “2022 Registration Statement”) and a prospectus supplement, pursuant to the 2022 Registration Statement, relating to the offer and sale of up to an
additional 4,551,438 common shares of the Trust under the Trust’s then current equity shelf offering program. As of August 2025, the offering of unsold shares pursuant to the 2022 Registration Statement has been terminated.
During the six months ended December 31, 2025, there were no
shares sold by the Trust pursuant to its then current shelf offering. During the year ended June 30, 2025, the Trust sold 752,798 common shares and received proceeds (net of offering costs) of $4,721,030 through its then current shelf offering.
The net proceeds in excess of the net asset value of the shares sold were $97,698 for the year ended June 30, 2025. Offering costs (other than the applicable sales commissions) incurred in connection with the then current shelf offering were
borne directly by EVM. Eaton Vance Distributors, Inc. (EVD), an affiliate of EVM, is the distributor of the Trust’s shares and was entitled to receive a sales commission from the Trust of 1.00% of the gross sales price per share, a portion of
which was re-allowed to sales agents. The Trust was informed that the sales commissions retained by EVD during the year ended June 30, 2025 were $9,538.
7 Financial Instruments
The Trust may trade in financial instruments with off-balance
sheet risk in the normal course of its investing activities. These financial instruments may include forward foreign currency exchange contracts and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial
statement purposes. The notional or contractual amounts of these instruments represent the investment the Trust has in particular classes of financial instruments and do not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. A summary of obligations under these financial instruments at December 31, 2025 is included in the Portfolio
of Investments. At December 31, 2025, the Trust had sufficient cash and/or securities to cover commitments under these contracts.
The Trust is subject to foreign exchange risk in the normal
course of pursuing its investment objective. Because the Trust holds foreign currency denominated investments, the value of these investments and related receivables and payables may change due to future changes in foreign currency exchange rates.
To hedge against this risk, the Trust enters into forward foreign currency exchange contracts.
The Trust enters into forward foreign currency exchange
contracts that may contain provisions whereby the counterparty may terminate the contract under certain conditions, including but not limited to a decline in the Trust’s net assets below a certain level over a certain period of time, which
would trigger a payment by the Trust for those derivatives in a liability position. At December 31, 2025, the fair value of derivatives with credit-related contingent features in a net liability position was $92,360. At December 31, 2025, there were
no assets pledged as collateral by the Trust for such liability.
The over-the-counter (OTC) derivatives in which the Trust
invests are subject to the risk that the counterparty to the contract fails to perform its obligations under the contract. To mitigate this risk, the Trust has entered into an International Swaps and Derivatives Association, Inc. Master Agreement
(“ISDA Master Agreement”) or similar agreement with substantially all its derivative counterparties. An ISDA Master Agreement is a bilateral agreement between the Trust and a counterparty that governs certain OTC derivatives and
typically contains, among other things, set-off provisions in the event of a default and/or termination event as defined under the relevant ISDA Master Agreement. Under an ISDA Master Agreement, the Trust may, under certain circumstances, offset
with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment
in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy or
insolvency. Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Trust’s net assets decline by a stated percentage or the Trust fails to meet the terms of
its ISDA Master Agreements, which would cause the counterparty to accelerate payment by the Trust of any net liability owed to it.
The collateral requirements for derivatives traded under an
ISDA Master Agreement are governed by a Credit Support Annex to the ISDA Master Agreement. Collateral requirements are determined at the close of business each day and are typically based on changes in market values for each transaction under an
ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to a minimum transfer threshold amount before a transfer is required, which may vary by counterparty.
Collateral pledged for the benefit of the Trust and/or counterparty is held in segregated accounts by the Trust’s custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. The portion of such collateral representing
cash, if any, is reflected as deposits for derivatives collateral and, in the case of cash pledged by a counterparty for the benefit of the Trust, a corresponding liability on the Statement of Assets and Liabilities. Securities pledged by the Trust
as collateral, if any, are identified as such in the Portfolio of Investments.

8 Revolving Credit and Security Agreement
The Trust has entered into a Credit Agreement, as amended, (the
Agreement) with a bank to borrow up to a limit of $35 million pursuant to a revolving line of credit. Borrowings under the Agreement are secured by the assets of the Trust. Interest is generally charged at a rate above the Secured Overnight
Financing Rate (SOFR) and is payable monthly. Under the terms of the Agreement, in effect through April 30, 2026, the Trust pays a facility fee of 0.15% on the borrowing limit. In connection with the renewal of the Agreement on May 1, 2025, the
Trust also paid upfront fees of $17,500, which are being amortized to interest expense through April 30, 2026. The unamortized balance at December 31, 2025 is approximately $6,000 and is included in prepaid upfront fees on notes payable on the
Statement of Assets and Liabilities. The Trust is required to maintain certain net asset levels during the term of the Agreement. At December 31, 2025, the Trust had borrowings outstanding under the Agreement of $20,000,000 at an annual interest
rate of 4.70%. Based on the short-term nature of the borrowings under the Agreement and the variable interest rate, the carrying amount of the borrowings at December 31, 2025 approximated its fair value. If measured at fair value, borrowings under
the Agreement would have been considered as Level 2 in the fair value hierarchy (see Note 10) at December 31, 2025. For the six months ended December 31, 2025, the average borrowings under the Agreement and the average annual interest rate
(excluding fees) were $18,945,652 and 5.10%, respectively.
9 Affiliated Investments
At December 31, 2025, the value of the Trust's investment in
funds that may be deemed to be affiliated was $2,105,614, which represents 2.0% of the Trust's net assets applicable to common shares. Transactions in such investments by the Trust for the six months ended December 31, 2025 were as follows:

10 Fair Value
Measurements
Under generally accepted accounting
principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels
listed below.
| • | Level 1 – quoted prices in active markets for identical investments |
| • | Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.) |
| • | Level 3 – significant unobservable inputs (including a fund's own assumptions in determining the fair value of investments) |
In cases where the inputs used to measure fair value fall in
different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not
necessarily an indication of the risk associated with investing in those securities.
At December 31, 2025, the hierarchy of inputs used in valuing
the Trust’s investments and open derivative instruments, which are carried at fair value, were as follows:
| Asset Description | Level 1 | Level 2 | Level 3* | Total |
| Asset-Backed Securities | $ — | $ 8,589,416 | $ — | $ 8,589,416 |
| Common Stocks | 11,681 | 1,825,232 | 0 | 1,836,913 |
| Corporate Bonds | — | 5,735,277 | — | 5,735,277 |
| Preferred Stocks | — | 64,281 | 99,904 | 164,185 |
| Senior Floating-Rate Loans (Less Unfunded Loan Commitments) | — | 141,900,260 | 161,265 | 142,061,525 |
| Warrants | — | — | 0 | 0 |
| Miscellaneous | — | — | 0 | 0 |

11 Risks and Uncertainties
Risks Associated with Foreign Investments
Foreign investments can be adversely affected by political,
economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country, and by acts of terrorism and war. There may be less publicly available information about foreign issuers
because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United
States. Trading in foreign markets typically involves higher expense than trading in the United States. The Trust may have difficulties enforcing its legal or contractual rights in a foreign country. Securities that trade or are denominated in
currencies other than the U.S. dollar may be adversely affected by fluctuations in currency exchange rates.
Credit Risk
The Trust invests primarily in below investment grade
floating-rate loans, which are considered speculative because of the credit risk of their issuers. Changes in economic conditions or other circumstances are more likely to reduce the capacity of issuers of these securities to make principal and
interest payments. Such companies are more likely to default on their payments of interest and principal owed than issuers of investment grade bonds. An economic downturn generally leads to a higher non-payment rate, and a loan or other debt
obligation may lose significant value before a default occurs. Lower rated investments also may be subject to greater price volatility than higher rated investments. Moreover, the specific collateral used to secure a loan may decline in value or
become illiquid, which would adversely affect the loan’s value.
12 Commitments and Contingencies
In connection with the Serta Chapter 11 bankruptcy proceeding,
on December 31, 2024, the U.S. Fifth Circuit Court of Appeals reversed a bankruptcy court’s ruling that held permissible an “uptier” agreement (the “2020 Agreement”) entered into by Serta with certain participating
lenders, including the Trust. The 2020 Agreement had the effect of subordinating the existing debt of certain non-participating lenders to that of the participating lenders. The non-participating lenders brought claims for breach of contract,
arguing that the participating lenders had breached an earlier agreement by entering into the 2020 Agreement. The appellate court found that the bankruptcy court had erred in determining that the 2020 Agreement was permitted by the terms of the
earlier agreement and remanded the breach of contract claims for further consideration by the bankruptcy court. The appellate court further held that indemnification of the participating lenders in the 2020 Agreement was impermissible under the U.S.
Bankruptcy Code.
A request by the Trust and the other
participating lenders for a rehearing of this matter before the Fifth Circuit en banc was denied. The matter has been remanded to the bankruptcy court to determine whether the participating lenders are liable for the breach of contract claims. A
trial is scheduled to begin in March 2026. At this time, the Trust cannot reliably predict the outcome of these proceedings or the effect, if any, on the Trust's net asset value.

IMPORTANT NOTICES
Delivery of Shareholder Documents. The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and
shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. Equiniti Trust Company, LLC (“EQ”), the closed-end funds transfer agent, or your financial intermediary, may household the mailing of your documents
indefinitely unless you instruct EQ, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact EQ or your financial
intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by EQ or your financial intermediary.
Portfolio
Holdings. Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) files a schedule of portfolio holdings on Part F to Form N-PORT with the
SEC. Certain information filed on Form N-PORT may be viewed on the Eaton Vance website at www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC’s website at www.sec.gov.

Share Repurchase
Program. The Fund’s Board of Trustees has approved a share repurchase program authorizing the Fund to repurchase up to 10% of its common shares
outstanding as of the last day of the prior calendar year in open-market transactions at a discount to net asset value. The repurchase program does not obligate the Fund to purchase a specific amount of shares. The Fund’s repurchase activity,
including the number of shares purchased, average price and average discount to net asset value, is disclosed in the Fund’s annual and semi-annual reports to shareholders.
Additional Notice to Shareholders. If applicable, a Fund may also redeem or purchase its outstanding preferred shares in order to maintain compliance with regulatory requirements, borrowing or
rating agency requirements or for other purposes as it deems appropriate or necessary.
