The Fund seeks to achieve this objective by investing under normal market conditions, at least 80% of its net assets (plus borrowings for investment purposes) in U.S. dollar denominated floating rate secured senior loans.

PERFORMANCE SUMMARY

During the period ended August 31, 2020, the Fund's Class A shares distributed total dividends of $0.22, which were all characterized as net investment income, resulting in an average annualized distribution rate⁽¹⁾ of 3.45%. The Fund's Class I and Class W shares each distributed total dividends of $0.23, which were all characterized as net investment income, resulting in an average annualized distribution rate⁽¹⁾ of 3.71% and 3.69%, respectively. During the same period, the Fund's Class C shares distributed total dividends of $0.19, which were all characterized as net investment income, resulting in an average annualized distribution rate⁽¹⁾ of 2.97%.

The Fund's total return for the period ended August 31, 2020, excluding sales charges and based on full reinvestment of dividends, for Class A, Class C, Class I and Class W was -7.89%, -8.14%, -7.71%, and -7.85%, respectively.⁽²⁾ For the same period, the S&P/LSTA Leveraged Loan Index (the "Index")⁽³⁾ had a total return of -0.52%.

⁽¹⁾ The distribution rate is calculated by annualizing the dividends and distributions declared during the last month of the period (i.e., divide the current month's dividend by the number of days in the related month and multiply by the number of days in the fiscal year) and then dividing the resulting figure by the reporting period-end NAV. The distribution rate is based solely on the actual dividends and distributions, which are made at the discretion of management. The distribution rate includes distributions from net investment income. The tax characterization of dividends and distributions will be determined after the Fund's tax year-end.

⁽²⁾ Total returns shown include, if applicable, the effect of fee waivers and/or expense reimbursements by Voya Investments, LLC. Had all fees and expenses been considered, the total returns would have been lower.

⁽³⁾ The Index is an unmanaged total return index that captures accrued interest, repayments, and market value changes. It represents a broad cross section of leveraged loans syndicated in the United States, including dollar-denominated loans to overseas issuers. Standard & Poor's and the Loan Syndications and Trading Association ("LSTA") conceived the Index to establish a performance benchmark for the syndicated leveraged loan industry. The Index is not subject to any fees or expenses. An investor cannot invest directly in an index.

PORTFOLIO MANAGERS' REPORT (continued)

Market Review: During the six-month period, the U.S. loan market and risk assets alike were subject to a relatively sharp market-dislocation in March that was caused by the global COVID-19 pandemic and the subsequent shuttering of economies across the globe to mitigate the spread of the coronavirus. The volatility brought forth by this external shock resulted in outsized and historic losses across virtually all asset classes. During this month the Index lost 12.37%, while high yield and equities lost 11.76% and 12.35% for the ICE BofA U.S. High Yield Index and S&P 500^® Index, respectively. Following this unprecedented drawdown, the U.S. Congress, the U.S. Federal Reserve and other central banks around the world enacted robust policy support to provide relief for consumers and businesses, and provide a much-needed liquidity backstop for credit markets. This coupled with a gradual increase in business activity, lifting of restrictive lockdown measures and improved investor sentiment, led to strong recoveries in April and in the ensuing months for senior loans and other asset class. Since the start of April, the overall return of the loan index has totaled an impressive 13.52%, and for the six-month period, the Index has nearly recouped all the losses suffered early in the timeframe with a total return of -0.52%.

The volatile backdrop had a strong impact on loan market technicals during this period. While primary market activity and collateralized loan obligation issuance were virtually put on pause in March-April, there was a steady upward trajectory on both fronts on a monthly basis. However, both measures lagged last year, and are behind the historical pace post-global financial crisis. Turning to credit fundamentals and default activity, the coronavirus pandemic resulted in notable liquidity challenges for the issuers directly exposed to the most material risks posed by COVID-19, particularly those that had business models severely impacted by shuttering of operations such as hotels, theaters, gyms, airlines and anything otherwise travel and leisure-related. As a result, this triggered an unprecedented wave of downgrade actions by rating agencies. For reference, the rolling three-month ratio downgrades to upgrades was 23.4x in April. Since then, downgrade activity appears to have abated, as we believe the worst of the coronavirus-induced downgrade actions has already been reflected in the initial wave. From a default perspective, the loan market saw a notable uptick in default activity in April-June, with many of the defaulted loans rooted in the energy space and the struggling retail sector. Although the pace of default has recently slowed somewhat, the loan market's trailing 12-month default rate by principal amount closed out August at 4.08%.

Portfolio Specifics: At -7.71%, Class I shares of the Fund underperformed the Index (which reflects no cash allocation or expenses) of -0.52%. The underperformance of the Fund was significantly magnified by its use of leverage

PORTFOLIO MANAGERS' REPORT (continued)

during a period of extreme market volatility and steep marked-to-market price declines in the loan market, all of which occurred in March.

On an industry basis, relative performance was negatively impacted by the Fund's overweight to some of the most significant industry laggards over the period, such as leisure goods/activities/movies, nonferrous metals/minerals and forest products. In addition, relative return was negatively impacted by an underweight to certain industry sectors that, while not generally high yielding, have proven in our view to be relatively insulated from the COVID-19 pandemic, such as food products, steel, drugs, ecological services and equipment and electronics/electrical. At an issuer level, an underweight to six of the top 10 index loan performers and an overweight to 24 Hour Fitness (one of the bottom 10 index loan performers over the period) also detracted from relative returns. As to the latter, the company filed for bankruptcy during the six-month timeframe (largely a by-product of the coronavirus-related shutdowns), and we continue to seek to manage the exposure through the restructuring process.

Conversely, relative performance was boosted by an underweight to air transport, home furnishings, oil and gas, conglomerates, clothing/textiles and retailers (except food and drug) which were all some of the worst industry performers in the Index over the period. Additionally, the portfolio benefited from its positioning in some of the top index industry performers, which included insurance and containers and glass products. From an individual issuer perspective, relative performance was helped by an overweight to four of the top 10 index loan performers for the period, as well as the avoidance of eight of the bottom 10 index loan performers, which included defaulted companies within the retail space such as J. Crew Group, Revlon Consumer Products Corp, J.C. Penney Company Inc and Neiman Marcus Group Inc.

The average issuer exposure at period-end stood at 0.34% of assets under management. The Fund had five defaults during the period, as compared to 34 defaults for the Index. The list of Fund defaults included Longview Power LLC, SkillSoft Corporation, 24 Hour Fitness Worldwide, Inc., Covia Holdings Corporation and Tailored Brands.

Current Strategy and Outlook: Since the depth of the severe dislocation in March, a strong technical rally and the easing of downgrade and default pressures has resulted in what we view as an impressive price recovery in a good portion of the loan market. Although we largely expect the current momentum to continue, barring any exogenous shock, there are several key macro factors that warrant a degree of caution. Included in this list is the growing consensus that the recent growth of the U.S. economy will likely decelerate in the coming months, as the initial surge related to the reopening of businesses across the country begins to dissipate. Moreover, the prospects of further fiscal policy support appear dim at the moment in our opinion, and the ongoing tug-of-war between vaccine development news and coronavirus flare-ups will continue to have influence over political and market sentiment. Lastly, we think the upcoming U.S. election cycle will to bring an additional level of noise and uncertainty to risk markets.

Ratings Distribution as of August 31, 2020
Ba or above	24.50	%
B	68.02	%
Caa1 or below	4.24	%
Not rated*	3.24	%

Loan ratings apply to the underlying holdings of the Fund and not the Fund itself. Ratings distribution shows the percentage of the Fund's loan commitments (excluding cash and foreign cash) that are rated in each ratings category, based upon the categories provided by Moody's Investors Service, Inc. Ratings distribution is based on Moody's senior secured facility ratings. Moody's ratings classification methodology: Aaa rating denotes the least credit risk; C rating denotes the greatest credit risk. Loans rated below Baa by Moody's are considered to be below investment-grade. When a loan is not rated by Moody's, it is designated as "Not Rated." Ratings can change from time to time, and current ratings may not fully reflect the actual credit condition or risks posed by a loan.

* Not rated includes loans to non-U.S. borrowers (which are typically unrated) and loans for which the rating has been withdrawn.

⁽¹⁾ Yield is calculated by dividing the Fund's net investment income per share for the most recent thirty days by the net asset value. Yield calculations do not include any commissions or sales charges, and are compounded for six months and annualized for a twelve-month period to derive the Fund's yield consistent with the U.S. Securities and Exchange Commission ("SEC") standardized yield formula.

⁽²⁾ The distribution rate is calculated by annualizing the dividends declared during the last month of the period (i.e., divide the current month's dividend by the number of days in the related month and multiply by the number of days in the fiscal year) and then dividing the resulting figure by the reporting period-end NAV. The distribution rate is based solely on the actual dividends and distributions, which are made at the discretion of management. The distribution rate includes distributions from net investment income. The tax characterization of dividends and distributions will be determined after the Fund's tax year-end.

In pursuit of its investment objectives, the Fund may seek to increase or decrease its exposure to the following market or credit risk factors:

Derivative Risk: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investments, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Fund to the risk of improper valuation.

Credit Risk: Prices of the Fund's investments are likely to fall if the actual or perceived financial health of the borrowers on, or issuers of, such investments deteriorates, whether because of broad economic or issuer-specific reasons, or if the borrower or issuer is late (or defaults) in paying interest or principal. The Fund invests a substantial portion of its assets in below investment-grade senior loans and other below investment-grade assets. Below investment-grade loans commonly known as high-yielding, high risk investments or as "junk" investments involve a greater risk that borrowers may not make timely payment of the interest and principal due on their loans and are subject to greater levels of credit and liquidity risks. They also involve a greater risk that the value of such loans could decline significantly. If borrowers do not make timely payments of the interest due on their loans, the yield on the Fund's Common Shares will decrease. If borrowers do not make timely payment of the principal due on their loans, or if the value of such loans decreases, the value of the Fund's net asset value ("NAV") will decrease.

Voya Senior Income Fund

PORTFOLIO MANAGERS' REPORT (continued)

Interest Rate Risk: Changes in short-term market interest rates will directly affect the yield on Common Shares. If short-term market interest rates fall, the yield on Common Shares will also fall. To the extent that the interest rate spreads on loans in the Fund's portfolio experience a general decline, the yield on the Common Shares will fall and the value of the Fund's assets may decrease, which will cause the Fund's NAV to decrease. Conversely, when short-term market interest rates rise, because of the lag between changes in such short-term rates and the resetting of the floating rates on assets in the Fund's portfolio, the impact of rising rates will be delayed to the extent of such lag. In the case of inverse securities, the interest rate paid by such securities generally will decrease when the market rate of interest to which the inverse security is indexed increases. With respect to investments in fixed rate instruments, a rise in market interest rates generally causes values of such instruments to fall. The values of fixed rate instruments with longer maturities or duration are more sensitive to changes in market interest rates.

As of the date of this report, the United States experiences a low interest rate environment, which may increase the Fund's exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility which could reduce liquidity for certain investments, adversely affect values, and increase costs. If dealer capacity in fixed-income and related markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the fixed-income and related markets. Further, recent and potential changes in government policy may affect interest rates.

Leverage Risk: The use of leverage through borrowings or the issuance of Preferred Shares can adversely affect the yield on the Common Shares. To the extent that the Fund is unable to invest the proceeds from the use of leverage in assets which pay interest at a rate which exceeds the rate paid on the leverage, the yield on the Common Shares will decrease. In addition, in the event of a general market decline in the value of assets such as those in which the Fund invests, the effect of that decline will be magnified in the Fund because of the additional assets purchased with the proceeds of the leverage. Further, because the fee paid to the Adviser will be calculated on the basis of Managed Assets, the fee will be higher when leverage is utilized, giving the Adviser an incentive to utilize leverage. The Fund is subject to certain restrictions imposed by lenders to the Fund and may be subject to certain restrictions imposed by guidelines of one or more rating agencies which may issue ratings for debt or the Preferred Shares issued by the Fund. These restrictions are expected to impose asset coverage, fund composition requirements and limits on investment techniques, such as the use of financial derivative products that are more stringent than those imposed on the Fund by the Investment Company Act of 1940, as amended (the "1940 Act"). These restrictions could impede the manager from fully managing the Fund's portfolio in accordance with the Fund's investment objective and policies.

Liquidity Risk: The Fund does not repurchase its shares on a daily basis and no market for the Fund's Common Shares is expected to exist. To provide a measure of liquidity, the Fund will normally make monthly repurchase offers for not less than 5% of its outstanding Common Shares. If more than 5% of Common Shares are tendered, investors may not be able to completely liquidate their holdings in any one month. Shareholders also will not have liquidity between these monthly repurchase dates.

Voya Senior Income Fund

NOTES TO FINANCIAL STATEMENTS as of August 31, 2020 (Unaudited)

NOTE 1 — ORGANIZATION

Voya Senior Income Fund (the "Fund"), a Delaware statutory trust, is registered under the 1940 Act, as a continuously-offered, diversified, closed-end, management investment company. The Fund invests, under normal market conditions, at least 80% of its net assets, plus the amount of any borrowings, for investment purposes, in U.S. dollar denominated, floating rate secured senior loans, which generally are not registered under the Securities Act of 1933, as amended (the "1933 Act"), and contain certain restrictions on resale and cannot be sold publicly. These loans bear interest (unless otherwise noted) at rates that float periodically at a margin above the London Inter-Bank Offered Rate ("LIBOR") and other short-term rates. Effective April 2, 2001, the Fund commenced the offering of Class A and Class C shares to the public. Effective April 15, 2008, the Fund commenced the offering of Class I and Class W shares to the public.

The Fund currently has four classes of shares: A, C, I and W. Class A shares are subject to a sales charge of up to 2.50%. Effective June 30, 2020, Class A shares purchased in excess of $500,000 are not subject to a sales charge but are subject to an EWC of 1.00% if repurchased by the Fund within one year of purchase. Prior to June 30, 2020, Class A shares purchased in excess of $500,000 were not subject to a sales charge but were subject to an EWC of 1.00% if repurchased by the Fund within six months of purchase. Class C shares are subject to an EWC of 1.00% if repurchased by the Fund within one year of purchase.

To maintain a measure of liquidity, the Fund will offer to repurchase not less than 5% of its outstanding Common Shares on a monthly basis. This is a fundamental policy that cannot be changed without shareholder approval. The Fund may not offer to repurchase more than 25% of its outstanding Common Shares in any calendar quarter. Other than these monthly repurchases, no market for the Fund's Common Shares is expected to exist. The separate classes of shares differ principally in their distribution fees and shareholder servicing fees. All shareholders bear the common expenses of the Fund and earn income and realized gains/losses from the portfolio pro rata on the average daily net assets of each class, without distinction between share classes. Differences in the per share dividend rates generally result from differences in separate class expenses, including distribution fees and shareholder servicing fees.

Voya Investments, LLC ("Voya Investments" or the "Investment Adviser"), an Arizona limited liability company, serves as the Investment Adviser to the Fund. The Investment Adviser has engaged Voya Investment Management Co. LLC ("Voya IM" or the "Sub-Adviser"), a Delaware limited liability company, to serve as the Sub-Adviser to the Fund.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements. The Fund is considered an investment company under U.S. generally accepted accounting principles ("GAAP") and follows the accounting and reporting guidance applicable to investment companies.

A. Senior Loan and Other Security Valuation. The Fund is open for business every day the New York Stock Exchange ("NYSE") opens for regular trading (each such day, a "Business Day"). The net asset value ("NAV") per Common Share of each class of the Fund is determined each Business Day as of the close of the regular trading session ("Market Close"), as determined by the Consolidated Tape Association ("CTA"), the central distributor of transaction prices for exchange-traded securities (normally 4:00 p.m. Eastern time unless otherwise designated by the CTA). The data reflected on the consolidated tape provided by the CTA is generated by various market centers, including all securities exchanges, electronic communications networks, and third-market broker-dealers. The NAV per Common Share of each class of the Fund is calculated by dividing the value of the Fund's loan assets plus all cash and other assets (including accrued expenses but excluding capital and surplus) attributable to that class of

Table of Contents

Voya Senior Income Fund

NOTES TO FINANCIAL STATEMENTS as of August 31, 2020 (Unaudited) (continued)

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (continued)

Common Shares by the number of Common Shares outstanding. The NAV per Common Share is made available for publication. On days when the Fund is closed for business, Fund shares will not be priced and the Fund does not transact purchase and redemption orders. To the extent the Fund's assets are traded in other markets on days when the Fund does not price its shares, the value of the Fund's assets will likely change and you will not be able to purchase or redeem shares of the Fund.

Assets for which market quotations are readily available are valued at market value. A security listed or traded on an exchange is valued at its last sales price or official closing price as of the close of the regular trading session on the exchange where the security is principally traded or, if such price is not available, at the last sale price as of the Market Close for such security provided by the CTA. Bank loans are valued at the average of the averages of the bid and ask prices provided to an independent loan pricing service by brokers. Futures contracts are valued at the final settlement price set by an exchange on which they are principally traded. Listed options are valued at the mean between the last bid and ask prices from the exchange on which they are principally traded. Investments in open-end registered investment companies that do not trade on an exchange are valued at the end of day NAV per share. Investments in registered investment companies that trade on an exchange are valued at the last sales price or official closing price as of the close of the regular trading session on the exchange where the security is principally traded.

When a market quotation is not readily available or is deemed unreliable, the Fund will determine a fair value for the relevant asset in accordance with procedures adopted by the Board of Trustees ("Board"). Such procedures provide, for example, that: (a) Exchange-traded securities are valued at the mean of the closing bid and ask; (b) Debt obligations are valued using an evaluated price provided by an independent pricing service. Evaluated prices provided by the pricing service may be determined without exclusive reliance on quoted prices, and may reflect factors such as institution-size trading in similar groups of securities, developments related to specific securities, benchmark yield, quality, type of issue, coupon rate, maturity, individual trading characteristics and other market data; (c) Securities traded in the over-the-counter market are valued based on prices provided by independent pricing services or market makers; (d) Options not listed on an exchange are valued by an independent source using an industry accepted model, such as Black-Scholes; (e) Centrally cleared swap agreements are valued using a price provided by the central counterparty clearinghouse; (f) Over-the-counter swap agreements are valued using a price provided by an independent pricing service; (g) Forward foreign currency exchange contracts are valued utilizing current and forward rates obtained from an independent pricing service. Such prices from the third party pricing service are for specific settlement periods and the Fund's forward foreign currency exchange contracts are valued at an interpolated rate between the closest preceding and subsequent period reported by the independent pricing service; and (h) Securities for which market prices are not provided by any of the above methods may be valued based upon quotes furnished by brokers.

The prospectuses of the open-end registered investment companies in which the Fund may invest explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.

Foreign securities' (including forward foreign currency exchange contracts) prices are converted into U.S. dollar amounts using the applicable exchange rates as of Market Close. If market quotations are available and believed to be reliable for foreign exchange-traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before Market Close, closing market quotations may become unreliable. An independent pricing service determines the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current value as of Market Close. Foreign securities' prices meeting the approved degree of certainty that the price is not reflective of current value will be valued by the independent pricing service using pricing models designed to estimate likely changes in the values of

NOTES TO FINANCIAL STATEMENTS as of August 31, 2020 (Unaudited) (continued)

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (continued)

those securities between the times in which the trading in those securities is substantially completed and Market Close. Multiple factors may be considered by the independent pricing service in determining the value of such securities and may include information relating to sector indices, American Depositary Receipts and domestic and foreign index futures.

All other assets for which market quotations are not readily available or became unreliable (or if the above fair valuation methods are unavailable or determined to be unreliable) are valued at fair value as determined in good faith by or under the supervision of the Board following procedures approved by the Board. The Board has delegated to the Investment Adviser responsibility for overseeing the implementation of the Fund's valuation procedures; a "Pricing Committee" comprised of employees of the Investment Adviser or its affiliates has responsibility for applying the fair valuation methods set forth in the procedures and, if a fair valuation cannot be determined pursuant to the fair valuation methods, determining the fair value of assets held by the Fund. Issuer specific events, transaction price, position size, nature and duration of restrictions on disposition of the security, market trends, bid/ask quotes of brokers and other market data may be reviewed in the course of making a good faith determination of a security's fair value. Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer's assets, general economic conditions, interest rates, investor perceptions and market liquidity. Because of the inherent uncertainties of fair valuation, the values used to determine the Fund's NAV may materially differ from the value received upon actual sale of those investments. Thus, fair valuation may have an unintended dilutive or accretive effect on the value of shareholders' investments in the Fund.

Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Quoted prices in active markets for identical securities are classified as "Level 1," inputs other than quoted prices for an asset or liability that are observable are classified as "Level 2" and unobservable inputs, including the Sub-Adviser's or Pricing Committee's judgment about the assumptions that a market participant would use in pricing an asset or liability are classified as "Level 3." The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Short-term securities of sufficient credit quality are generally considered to be Level 2 securities under applicable accounting rules. A table summarizing the Fund's investments under these levels of classification is included within the Portfolio of Investments.

GAAP requires a reconciliation of the beginning to ending balances for reported fair values that presents changes attributable to total realized and unrealized gains or losses, purchases and sales, and transfers in or out of the Level 3 category during the period. A reconciliation of Level 3 investments within the Portfolio of Investments is presented only when the Fund has a significant amount of Level 3 investments.

B. Security Transactions and Revenue Recognition. Security transactions and senior loans are accounted for on the trade date (date the order to buy or sell is executed). Realized gains or losses are reported on the basis of identified cost of securities sold. Interest income is recorded on an accrual basis at the then-current loan rate. The accrual of interest on loans is partially or fully discontinued when, in the opinion of management, there is an indication that the borrower may be unable to meet payments as they become due. If determined to be uncollectible, unpaid accrued interest is also written off. Cash collections on non-accrual senior loans are generally applied as a reduction to the recorded investment of the loan. Senior loans are generally returned to accrual status only after all past due amounts have been received and the borrower has demonstrated sustained performance. Premium amortization and discount accretion are deferred and recognized over the lives of the respective loans. Arrangement fees received on revolving credit facilities, which represent non-refundable fees or purchase discounts associated with the acquisition of loans, are deferred and recognized using the effective yield method over the shorter of four years or the actual term of the loan. No such fees are recognized on loans which have been placed on non-accrual status. Arrangement fees associated with all other loans, except

Voya Senior Income Fund

NOTES TO FINANCIAL STATEMENTS as of August 31, 2020 (Unaudited) (continued)

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (continued)

revolving credit facilities, are treated as discounts and are accreted as described above. Dividend income is recorded on the ex-dividend date. Amendment fees are earned as compensation for evaluating and accepting changes to an original senior loan agreement and are recognized when received. Amendment fees and other fees earned are reported on the Statement of Operations.

C. Foreign Currency Translation. The books and records of the Fund are maintained in U.S. dollars. Any foreign currency amounts are translated into U.S. dollars on the following basis:

(1) Market value of investment securities, other assets and liabilities — at the exchange rates prevailing at Market Close.

(2) Purchases and sales of investment securities, income and expenses — at the rates of exchange prevailing on the respective dates of such transactions.

Although the net assets and the market values are presented at the foreign exchange rates at Market Close, the Fund does not isolate the portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gains or losses from investments. For securities, which are subject to foreign withholding tax upon disposition, liabilities are recorded on the Statement of Assets and Liabilities for the estimated tax withholding based on the securities current market value. Upon disposition, realized gains or losses on such securities are recorded net of foreign withholding tax.

Reported net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund's books, and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities other than investments in securities, resulting from changes in the exchange rate. Foreign security and currency transactions may involve certain considerations and risks not typically associated with investing in U.S. companies and the U.S. government. These risks include, but are not limited to, revaluation of currencies and future adverse political and economic developments which could cause securities and their markets to be less liquid and prices more volatile than those of comparable U.S. companies and U.S. government securities. The foregoing risks are even greater with respect to securities of issuers in emerging markets.

D. Forward Foreign Currency Contracts. The Fund has entered into forward foreign currency contracts primarily to hedge against foreign currency exchange rate risks on its non-U.S. dollar denominated investment securities. When entering into a currency forward foreign contract, the Fund agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. These contracts are valued daily and the Fund's net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in the Statement of Assets and Liabilities. Realized and unrealized gains and losses are included in the Statement of Operations. These instruments involve market and/or credit risk in excess of the amount recognized in the Statement of Assets and Liabilities. Risks arise from the possible inability of counterparties to meet the terms of their contracts and from movement in currency and securities values and interest rates. Open forward foreign currency contracts are presented within the respective Portfolio of Investments.

For the period ended August 31, 2020, the Fund had an average quarterly contract amount on forward foreign currency contracts to buy and sell of $3,444,807 and $18,958,992, respectively. Please refer to the table within the Portfolio of Investments for open forward foreign currency contracts to sell at August 31, 2020.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (continued)

E. When-Issued Delayed-Delivery. Securities purchased or sold on a when-issued, delayed-delivery or forward purchase commitment basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. Due to the nature of the Senior Loan market, the actual settlement date may not be certain at the time of the purchase or sale for some of the Senior Loans. Interest income on such Senior Loans is not accrued until settlement date.

F. Federal Income Taxes. It is the policy of the Fund to comply with the requirements of subchapter M of the Internal Revenue Code that are applicable to regulated investment companies and to distribute substantially all of their net investment income and any net realized capital gains to their shareholders. Therefore, a federal income tax or excise tax provision is not required. Management has considered the sustainability of the Fund's tax positions taken on federal income tax returns for all open tax years in making this determination. No capital gain distributions shall be made until the capital loss carryforwards have been fully utilized.

The Fund may utilize equalization accounting for tax purposes, whereby a portion of redemption payments are treated as distributions of income or gain.

G. Distributions to Shareholders. The Fund declares and goes ex-dividend daily and pays dividends monthly from net investment income. Distributions from capital gains, if any, are declared and paid annually. The Fund may make additional distributions to comply with the distribution requirements of the Internal Revenue Code. The character and amounts of income and gains to be distributed are determined in accordance with federal income tax regulations, which may differ from GAAP for investment companies. Distributions in excess of net investment income and/or net realized capital gains for tax purposes are reported as return of capital. The Fund records distributions to its shareholders on the ex-dividend date.

H. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

I. Indemnifications. In the normal course of business, the Fund may enter into contracts that provide certain indemnifications. The Fund's maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated; however, based on experience, management considers the risk of loss from such claims remote.

NOTE 3 — INVESTMENTS

For the period ended August 31, 2020, the cost of purchases and the proceeds from principal repayment and sales of investments, excluding short-term investments, totaled $43,170,404 and $106,520,298, respectively. At August 31, 2020, the Fund held senior loans valued at $258,559,940 representing 99.8% of its total investments. The fair value of these assets is established as set forth in Note 2.

The senior loans acquired by the Fund typically take the form of a direct lending relationship with the borrower, and are typically acquired through an assignment of another lender's interest in a loan. The lead lender in a typical corporate loan syndicate administers the loan and monitors the collateral securing the loan. In the event that the lead lender becomes insolvent, enters Federal Deposit Insurance Corporation ("FDIC") receivership or, if not FDIC insured, enters into bankruptcy, the Fund may incur certain costs and delays in realizing payment, or may suffer a loss of principal and/or interest.

Warrants and shares of common stock held in the portfolio were acquired in conjunction with loans held by the Fund. Certain of these shares and warrants are restricted and may not be publicly sold without registration under the 1933 Act, or without an exemption under the 1933 Act. In some cases, these restrictions expire after a designated period of time after the issuance of the shares or warrants.

NOTES TO FINANCIAL STATEMENTS as of August 31, 2020 (Unaudited) (continued)

NOTE 4 — INVESTMENT MANAGEMENT FEES

The Fund has entered into an investment management agreement ("Management Agreement") with the Investment Adviser. The Investment Adviser has overall responsibility for the management of the Fund. The Investment Adviser oversees all investment advisory and portfolio management services for the Fund and assists in managing and supervising all aspects of the general day-to-day business activities and operations of the Fund, including custodial, transfer agency, dividend disbursing, accounting, auditing, compliance and related services. This Management Agreement compensates the Investment Adviser with a fee, computed daily and payable monthly, at an annual rate of 0.90% of the Fund's Managed Assets. For purposes of the Management Agreement, managed assets ("Managed Assets") are defined as the Fund's average daily gross asset value, minus the sum of the Fund's accrued and unpaid dividends on any outstanding Preferred Shares and accrued liabilities (other than liabilities for the principal amount of any borrowings incurred, commercial paper or notes issued by the Fund and the liquidation preference of any outstanding Preferred Shares).

The Investment Adviser has entered into a sub-advisory agreement with Voya IM. Voya IM provides investment advice for the Fund and is paid by the Investment Adviser based on the average daily Managed Assets of the Fund. Subject to such policies as the Board or the Investment Adviser may determine, Voya IM manages the Fund's assets in accordance with the Fund's investment objectives, policies, and limitations.

NOTE 5 — DISTRIBUTION AND SERVICE FEES

Class A and Class C shares of the Fund have adopted a plan pursuant to Rule 12b-1 under the 1940 Act (the "12b-1 Plans"), whereby Voya Investments Distributor, LLC (the "Distributor"), a Delaware limited liability company, is compensated by the Fund for expenses incurred in the distribution of the Fund's shares ("Distribution Fees"). Pursuant to the 12b-1 Plans, the Distributor is entitled to a payment each month for actual expenses incurred in the distribution and promotion of the Fund's shares, including expenses incurred in printing prospectuses and reports used for sales purposes, expenses incurred in preparing and printing sales literature and other such distribution related expenses, including any distribution or shareholder servicing fees ("Service Fees") paid to securities dealers who executed a distribution agreement with the Distributor. Under the 12b-1 plans, each class of shares of the Fund pays the Distributor a combined Distribution and/or Service Fee based on average daily net assets at the following annual rates:

Class A				Class C
	0.25	%			0.75	%

The Distributor may also retain the proceeds of the initial sales charge paid by the shareholders upon the purchase of Class A shares, and the EWC paid by the shareholders upon certain redemptions/repurchases for Class A shares and Class C shares. For the period ended August 31, 2020, the Distributor retained the following amounts in EWC's:

	Class A		Class C
Initial Sales Charges:	$	637	$	—
EWC's:		—		228

NOTE 6 — EXPENSE LIMITATIONS

The Investment Adviser has agreed to limit expenses, excluding interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and acquired fund fees and expenses, to the following:

Class A — 0.90% of Managed Assets plus 0.45% of average daily net assets
Class C — 0.90% of Managed Assets plus 0.95% of average daily net assets

NOTE 7 — COMMITMENTS

Effective May 8, 2020, the Fund has entered into a 364-day revolving credit agreement, collateralized by assets of the Fund, to borrow up to $114 million maturing May 7, 2021.

NOTE 9 — TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

The Fund has adopted a deferred compensation plan (the "DC Plan"), which allows eligible independent trustees, as described in the DC Plan, to defer the receipt of all or a portion of the trustees' fees that they are entitled to receive from the Fund. For purposes of determining the amount owed to the trustee under the DC Plan, the amounts deferred are invested in shares of the funds selected by the trustee (the "Notional Funds"). The Fund purchases shares of the Notional Funds, which are all advised by Voya Investments, in amounts equal to the trustees' deferred fees, resulting in a Fund asset equal to the deferred compensation liability. Such assets, if applicable, are included as a component of "Other assets" on the accompanying Statement of Assets and Liabilities. Deferral of trustees' fees under the DC Plan will not affect net assets

of the Fund, and will not materially affect the Fund's assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance with the DC Plan.

The Fund may engage in purchase and sale transactions with funds that have a common investment adviser (or affiliated investment advisers) and/or have a common sub-adviser. These interfund transactions are made pursuant to Rule 17a-7 under the 1940 Act. For the period ended August 31, 2020, the Fund engaged in such purchase and sale transactions totaling $980,000 and $6,970,021, respectively.

NOTE 10 — SUBORDINATED LOANS AND UNSECURED LOANS

The primary risk arising from investing in subordinated loans or in unsecured loans is the potential loss in the event of default by the issuer of the loans. The Fund may invest up to 20% of its total assets, measured at the time of investment, in subordinated loans, unsecured debt instruments and other investments, as directed by the Prospectus. As of August 31, 2020, the Fund held no subordinated loans or unsecured loans.

NOTE 12 — FEDERAL INCOME TAXES

The amount of distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from GAAP for investment companies. These book/tax differences may be either temporary or permanent. Permanent differences are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences are not reclassified. Key differences include the treatment of short-term capital gains, foreign currency

transactions, and wash sale deferrals. Distributions in excess of net investment income and/or net realized capital gains for tax purposes are reported as return of capital.

Dividends paid by the Fund from net investment income and distributions of net realized short-term capital gains are, for federal income tax purposes, taxable as ordinary income to shareholders.

The tax composition of dividends and distributions to shareholders was as follows:

Year Ended February 29, 2020		Year Ended February 28, 2019
Ordinary Income		Ordinary Income
$	15,824,022	$	19,282,607

The tax-basis components of distributable earnings and the capital loss carryforwards which may be used to offset future realized capital gains for federal income tax purposes as of February 29, 2020 were:

Undistributed		Late Year			Post-October			Unrealized			Capital Loss Carryforwards
Ordinary		Ordinary Losses			Capital Losses			Appreciation/
Income		Deferred			Deferred			(Depreciation)			Amount			Character	Expiration
$	1,957,201	$	(30,346	)	$	(5,043,698	)	$	(20,362,391	)	$	(1,579,618	)	Short-term		None
												(62,863,808	)	Long-term		None
											$	(64,443,426	)

The Fund's major tax jurisdictions are U.S. federal and Arizona state.

As of August 31, 2020, no provision for income tax is required in the Fund's financial statements as a result of tax positions taken on federal and state income tax returns for open tax years. The Fund's federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state department of revenue. Generally, the preceding four tax years remain subject to examination by these jurisdictions.

NOTE 13 — MARKET DISRUPTION

The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. War, terrorism, global health crises and pandemics, and other geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and world economies and markets generally. For example, the recent COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, and a substantial economic downturn in economies throughout the world. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. Those events as well as other changes in non-U.S. and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the investments of the portfolio and of the Fund. Any of these occurrences could disrupt the operations of the Fund and of the Fund's service providers.

NOTE 14 — OTHER ACCOUNTING PRONOUNCEMENTS

The Fund has made a change in accounting principles and adopted the provisions of Financial Accounting Standards Board Accounting Standards Update 2018-13 ("ASU 2018-13"), Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 introduces new fair value disclosure requirements as well as provides guidance that eliminates, adds and modifies certain disclosure requirements for fair value measurements. The impact of the Fund's adoption was limited to changes in the Fund's financial statement disclosures regarding fair value, primarily those disclosures related to transfers between levels of the fair value hierarchy and disclosure of the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements, when applicable. Upon evaluation, the Fund has concluded that the adoption of the new accounting principle does not materially impact the financial statement amounts.

In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04 ("ASU 2020-04"), Reference Rate Reform (Topic 848) — Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in ASU 2020-04 provides optional temporary financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of LIBOR and other interbank-offered based reference rates as of the end of 2021. ASU 2020-04 is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022. Management is currently evaluating the impact, if any, of applying ASU 2020-04.
