President’s Letter

Dear Stockholder,

I am pleased to present this semi-annual report for Neuberger Berman Real Estate Securities Income Fund Inc. (the Fund) for the six months ended April 30, 2023 (the reporting period). The report includes a portfolio commentary, a listing of the Fund’s investments and its unaudited financial statements for the reporting period.

The Fund seeks to provide high current income with capital appreciation as a secondary objective. To pursue both, we have assembled a portfolio with a broad mix of equity securities of real estate investment trusts (REITs) and other real estate companies. Our investment approach combines analysis of security fundamentals and real estate with property sector diversification. Our disciplined valuation methodology seeks real estate company securities that we believe are attractively priced relative to both their historical growth rates and the valuation of other property sectors.

Thank you for your confidence in the Fund. We will continue to do our best to retain your trust in the years to come.

Sincerely,

Joseph V. Amato
President and CEO
Neuberger Berman Real Estate Securities Income Fund Inc.

Neuberger Berman Real Estate Securities Income Fund Inc.
Portfolio Commentary (Unaudited)

Neuberger Berman Real Estate Securities Income Fund Inc. (the Fund) generated a 7.02% total return on a net asset value (NAV) basis for the six-month period ended April 30, 2023 (the reporting period), outperforming its benchmark, the FTSE Nareit All Equity REITs Index (the Index), which provided a 2.79% total return for the same period. (Fund performance on a market price basis is provided in the table immediately following this commentary.) The use of leverage (typically a performance enhancer in up markets and a detractor during market retreats) contributed to the Fund’s performance during the reporting period.

The overall U.S. equity market, as measured by the S&P 500® Index, was volatile, but ultimately generated strong results during the reporting period. Investor sentiment fluctuated given incoming economic data and expectations for U.S. Federal Reserve Board (Fed) rate hikes to fight inflation. Repercussions from the war in Ukraine and turmoil in the regional banking industry, initially driven by the collapse of Silicon Valley Bank, also impacted the market. Despite concerns that elevated inflation could trigger a recession, the U.S. economy was resilient. All told, the S&P 500 Index returned 8.63% during the reporting period. Comparatively, Real Estate Investment Trusts (REITs), as measured by the Index, returned 2.79% during the period, partially supported by falling interest rates.

On average, the Fund had a 34% allocation to REIT preferred shares during the reporting period, which we invested to pursue the Fund’s dual objectives of income generation and capital appreciation. This contributed to absolute performance as preferred shares, as measured by the FTSE Nareit Preferred Stock Index, returned 8.58% during the reporting period.

Stock selection was additive for performance whereas sector allocation detracted from relative results. From a stock selection perspective, holdings in the Lodging/Resort, Diversified and Self Storage sectors were the most additive for returns. On the downside, the Data Centers sector was the only meaningful detractor from relative performance. In terms of sector positioning, an overweight to Mortgage Commercial Financing (not in the Index) and an underweight to Data Centers versus the Index were the largest headwinds for relative results. Conversely, the Fund’s exposure to Mortgage Home Financing and underweights to Office and Infrastructure REITs were the most beneficial for performance.

Looking ahead, we remain cautious as the macro backdrop is weighed down by a hawkish Fed determined to get inflation under control, slower economic growth, and lack of liquidity in both transaction markets and private investment vehicles. The global economy appears to be weakening, highlighted by slowing housing and low business confidence. However, we believe the reopening of China’s economy, lower energy and commodity prices, and a slowing labor market could provide some support for the view that inflation levels are peaking.

We believe that elevated cost of capital for REITs, paired with likely slowing fundamentals following a robust 2021/2022 leasing period, will likely stall business decisions and weigh on overall demand and earnings growth for REITs. We believe that a majority of REITs are prepared for a meaningful disruption to business demand, with strong balance sheets, relatively low new construction activity and diverse demand drivers that lean more defensive. The rapid reversal of fundraising by Non-Traded REITs (NTRs) and waves of redemption requests may provide a window of opportunity for REITs to selectively acquire assets at relatively attractive valuations. While we believe the macro backdrop will continue to weigh on the stocks, we will continue to focus on select companies with relatively better fundamentals, diverse demand drivers and strong balance sheets that we believe can withstand increased market volatility.

Sincerely,

Steve Shigekawa and Brian Jones

Listed closed-end funds, unlike open-end funds, are not continually offered. Generally, there is an initial public offering and, once issued, shares of common stock of closed-end funds are sold in the secondary market on a stock exchange.

The performance data quoted represent past performance and do not indicate future results. Current performance may be lower or higher than the performance data quoted. For current performance data, please visit www.nb.com/cef-performance.

The results shown in the table reflect the reinvestment of income dividends and other distributions, if any. The results do not reflect the effect of taxes a stockholder would pay on Fund distributions or on the sale of shares of the Fund’s common stock.

The investment return and market price will fluctuate and shares of the Fund’s common stock may trade at prices above or below NAV. Shares of the Fund’s common stock, when sold, may be worth more or less than their original cost.

Returns would have been lower if Neuberger Berman Investment Advisers LLC ("NBIA") had not waived a portion of its investment management fees during certain of the periods shown. The waived fees are from prior years that are no longer disclosed in the Financial Highlights.

Notes to Financial Statements Real Estate Securities Income Fund Inc. (Unaudited)

Note A—Summary of Significant Accounting Policies:

General: Neuberger Berman Real Estate Securities Income Fund Inc. (the "Fund") was organized as a Maryland corporation on August 28, 2003 as a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the status of a fund that was registered as non-diversified may, under certain circumstances, change to that of a diversified fund. The Fund is currently a diversified fund. The Fund’s Board of Directors (the "Board") may classify or re-classify any unissued shares of capital stock into one or more classes of preferred stock without the approval of stockholders.

A balance indicated with a "—", reflects either a zero balance or a balance that rounds to less than 1.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 946 "Financial Services—Investment Companies."

The preparation of financial statements in accordance with U.S. generally accepted accounting principles ("GAAP") requires Management to make estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates.

Portfolio valuation: In accordance with ASC 820 "Fair Value Measurement" ("ASC 820"), all investments held by the Fund are carried at the value that Management believes the Fund would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment under current market conditions. Various inputs, including the volume and level of activity for the asset or liability in the market, are considered in valuing the Fund's investments, some of which are discussed below. At times, Management may need to apply significant judgment to value investments in accordance with ASC 820.

ASC 820 established a three-tier hierarchy of inputs to create a classification of value measurements for disclosure purposes. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below.

•

Level 1 – unadjusted quoted prices in active markets for identical investments

•

Level 2 – other observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, amortized cost, etc.)

•

Level 3 – unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

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

The value of the Fund’s investments in equity securities, master limited partnerships and limited partnerships, and certain preferred stocks, for which market quotations are available, is generally determined by Management by obtaining valuations from independent pricing services based on the latest sale price quoted on a principal exchange or market for that security (Level 1 inputs). Securities traded primarily on the NASDAQ Stock Market are normally valued at the NASDAQ Official Closing Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most recently reported price as of 4:00:02 p.m., Eastern Time, unless that price is outside the range of the "inside" bid and asked prices (i.e., the bid and asked prices that dealers quote to each other when trading for their own accounts); in that case, NASDAQ will adjust the price to equal the inside bid or asked price, whichever is closer. Because of delays in reporting trades, the NOCP may not be based on the price of the last trade to occur before the market closes. If there is no sale of a security on a particular day, the independent pricing services may value the security based on market quotations. The value of certain preferred stock is determined by Management by obtaining

valuations from independent pricing services which are based on market information which may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and reference data, such as market research publications, when available (generally Level 2 inputs).

Management has developed a process to periodically review information provided by independent pricing services for all types of securities.

Investments in non-exchange traded investment companies are valued using the respective fund’s daily calculated net asset value ("NAV") per share (Level 2 inputs), when available.

If a valuation is not available from an independent pricing service, or if Management has reason to believe that the valuation received does not represent the amount the Fund might reasonably expect to receive on a current sale in an orderly transaction, Management seeks to obtain quotations from brokers or dealers (generally considered Level 2 or Level 3 inputs depending on the number of quotes available). If such quotations are not available, the security is valued using methods Management has approved in the good-faith belief that the resulting valuation will reflect the fair value of the security. Pursuant to Rule 2a-5 under the 1940 Act, the Board designated Management as the Fund's valuation designee. As the Fund's valuation designee, Management is responsible for determining fair value in good faith for any and all Fund investments. Inputs and assumptions considered in determining the fair value of a security based on Level 2 or Level 3 inputs may include, but are not limited to, the type of the security; the initial cost of the 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; quotations or evaluated prices from broker-dealers and/or pricing services; information obtained from the issuer and/or analysts; an analysis of the company’s or issuer’s financial statements; an evaluation of the inputs that influence the issuer and the market(s) in which the security is purchased and sold.

The value of the Fund’s investments in foreign securities is generally determined using the same valuation methods and inputs as other Fund investments, as discussed above. Foreign security prices expressed in local currency values are normally translated from the local currency into U.S. dollars using the exchange rates as of 4:00 p.m., Eastern Time on days the New York Stock Exchange ("NYSE") is open for business. Management has approved the use of ICE Data Services ("ICE") to assist in determining the fair value of foreign equity securities when changes in the value of a certain index suggest that the closing prices on the foreign exchanges may no longer represent the amount that the Fund could expect to receive for those securities or on days when foreign markets are closed and U.S. markets are open. In each of these events, ICE will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors (Level 2 inputs). In the absence of precise information about the market values of these foreign securities as of the time as of which the Fund's share price is calculated, Management has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices the Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade.

Fair value prices are necessarily estimates, and there is no assurance that such a price will be at or close to the price at which the security is next quoted or next trades.

Securities transactions and investment income: Securities transactions are recorded on trade date for financial reporting purposes. Dividend income is recorded on the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income, including accretion of discount (adjusted for original issue discount, where applicable), if any, is recorded on the accrual basis. Realized gains and losses from securities transactions are recorded on the basis of identified cost and stated separately in the Statement of Operations.

Income tax information: It is the policy of the Fund to continue to qualify for treatment as a regulated investment company ("RIC") by complying with the requirements of the U.S. Internal Revenue Code applicable to RICs and to distribute substantially all of its net investment income and net realized capital gains to its stockholders. To the extent the Fund distributes substantially all of its net investment income and net realized capital gains to stockholders, no federal income or excise tax provision is required.

ASC 740 "Income Taxes" sets forth a minimum threshold for financial statement recognition of a tax position taken, or expected to be taken, in a tax return. The Fund recognizes interest and penalties, if any, related to unrecognized tax positions as an income tax expense in the Statement of Operations. The Fund is subject to examination by U.S. federal and state tax authorities for returns filed for the tax years for which the applicable statutes of limitations have not yet expired. Management has analyzed the Fund's tax positions taken or expected to be taken on federal and state income tax returns for all open tax years (the current and the prior three tax years) and has concluded that no provision for income tax is required in the Fund's financial statements.

For federal income tax purposes, the estimated cost of investments held at April 30, 2023 was $245,489,753. The estimated gross unrealized appreciation was $17,123,083 and estimated gross unrealized depreciation was $38,292,656 resulting in net unrealized depreciation in value of investments of $21,169,573 based on cost for U.S. federal income tax purposes.

Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences are primarily due to differing treatments of income and gains on various investment securities held by the Fund, timing differences and differing characterization of distributions made by the Fund.

Any permanent differences resulting from different book and tax treatment are reclassified at year-end and have no impact on net income, NAV or NAV per share of common stock of the Fund. For the year ended October 31, 2022, the Fund recorded permanent reclassifications primarily related to prior year true up adjustment on real estate investment trusts ("REITs"). For the year ended October 31, 2022, the Fund recorded the following permanent reclassifications:

	Paid-in Capital	Total Distributable Earnings/(Losses)
	$(1,775,394 )	$1,775,394

The tax character of distributions paid during the years ended October 31, 2022, and October 31, 2021, was as follows:

Distributions Paid From:
Ordinary Income		Long-Term Capital Gain		Return of Capital		Total
2022	2021	2022	2021	2022	2021	2022	2021
$5,899,759	$6,978,362	$—	$—	$11,864,748	$11,612,787	$17,764,507	$18,591,149

As of October 31, 2022, the components of distributable earnings (accumulated losses) on a U.S. federal income tax basis were as follows:

	Undistributed Ordinary Income	Undistributed Long-Term Capital Gain	Unrealized Appreciation/ (Depreciation)	Loss Carryforwards and Deferrals	Other Temporary Differences	Total
	$—	$—	$(35,968,534 )	$(14,918,776 )	$(62,310 )	$(50,949,620 )

The temporary differences between book basis and tax basis distributable earnings are primarily due to timing differences of fund level distributions, losses disallowed and/or recognized on wash sales and tax adjustments related to partnerships.

To the extent the Fund’s net realized capital gains, if any, can be offset by capital loss carryforwards, it is the policy of the Fund not to distribute such gains. Capital loss carryforward rules allow for RICs to carry forward capital losses indefinitely and to retain the character of capital loss carryforwards as short-term or

long-term. As determined at October 31, 2022, the Fund had unused capital loss carryforwards available for federal income tax purposes to offset future net realized capital gains, if any, as follows:

Capital Loss Carryforwards
Long-Term	Short-Term
$12,174,088	$2,744,688

During the fiscal year ended October 31, 2022, the Fund had utilized capital loss carryforwards of $9,413,239.

Foreign taxes: Foreign taxes withheld, if any, represent amounts withheld by foreign tax authorities, net of refunds recoverable.

Distributions to common stockholders: The Fund earns income, net of expenses, daily on its investments. It is the policy of the Fund to declare and pay monthly distributions to common stockholders. The Fund has adopted a policy to pay common stockholders a stable monthly distribution. The Fund’s ability to satisfy its policy will depend on a number of factors, including the amount and stability of income received from its investments, the availability of capital gains, interest paid on any borrowings and the level of other Fund fees and expenses. In an effort to maintain a stable distribution amount, the Fund may pay distributions consisting of net investment income, net realized gains and paid-in capital. There is no assurance that the Fund will always be able to pay distributions of a particular size, or that distributions will consist solely of net investment income and net realized capital gains. The composition of the Fund’s distributions for the calendar year 2023 will be reported to Fund stockholders on IRS Form 1099-DIV. The Fund may pay distributions in excess of those required by its stable distribution policy to avoid excise tax or to satisfy the requirements of Subchapter M of the Internal Revenue Code. Distributions to common stockholders are recorded on the ex-date. Net realized capital gains, if any, will be offset to the extent of any available capital loss carryforwards. Any such offset will not reduce the level of the stable monthly distribution paid by the Fund.

The Fund invests a significant portion of its assets in securities issued by real estate companies, including REITs. The distributions received from REITs are generally composed of income, capital gains, and/or return of REIT capital, but the REITs do not report this information to the Fund until the following calendar year. For the year ended October 31, 2022, the character of distributions paid to stockholders of the Fund, if any, disclosed within the Statements of Changes in Net Assets was based on estimates made at that time. Based on past experience it is possible that a portion of the Fund’s distributions during the current fiscal year, if any, will be considered tax return of capital, but the actual amount of the tax return of capital, if any, is not determinable until after the Fund’s fiscal year-end. After calendar year-end, when the Fund learns the nature of the distributions paid by REITs during that year, distributions previously identified as income may be re-characterized as return of capital and/or capital gain. After all applicable REITs have informed the Fund of the actual breakdown of distributions paid to the Fund during its fiscal year, estimates previously recorded are adjusted to reflect actual results. As a result, the composition of the Fund’s distributions as reported herein may differ from the final composition determined after calendar year-end and reported to Fund stockholders on IRS Form 1099-DIV.

On April 28, 2023, the Fund declared a monthly distribution to common stockholders in the amount of $0.0312 per share, payable on May 31, 2023 to stockholders of record on May 15, 2023, with an ex-date of May 12, 2023. Subsequent to April 30, 2023, the Fund declared a monthly distribution on May 31, 2023 to common stockholders in the amount of $0.0312 per share, payable on June 30, 2023 to stockholders of record on June 15, 2023, with an ex-date of June 14, 2023.

Expense allocation: Certain expenses are applicable to multiple funds within the complex of related investment companies. Expenses directly attributable to the Fund are charged to the Fund. Expenses borne by the complex of related investment companies, which includes open-end and closed-end investment companies for which NBIA serves as investment manager, that are not directly attributable to a particular

investment company (e.g., the Fund) are allocated among the Fund and the other investment companies or series thereof in the complex on the basis of relative net assets, except where a more appropriate allocation of expenses to each of the investment companies or series thereof in the complex can otherwise be made fairly.

Financial leverage: In September 2014, the Fund entered into a $125 million secured, committed five-year credit facility (the "Old Facility") with State Street Bank and Trust Company ("State Street"). Under the Old Facility, State Street made a Term Loan of $75 million and committed to making revolving LIBOR Loans and Base Rate Loans of up to $50 million.

In September 2019, the Fund amended and extended the Old Facility and reduced the size of the Old Facility to $100 million (as so amended and extended, the "Current Facility"). Under the Current Facility, in 2019 State Street made a 3-year Term Loan of $30 million due September 2022 and a 5-year Term Loan of $30 million due September 2024 and committed to making revolving LIBOR Loans and Base Rate Loans of up to $40 million. In March 2020, the Fund repaid the $30 million 3-year Term Loan due September 2022. After the repayment, the amount of the Fund's outstanding fixed-rate borrowings under the Current Facility was reduced to $30 million, consisting of the 5-year Term Loan due September 2024. In November 2021, the Fund amended the Current Facility to increase the total commitment amount under the revolving credit facility from $40 million to $70 million. In December 2022, the Fund amended the Current Facility to address the discontinuation of certain LIBOR-based interest rates and provide for the commitment to make revolving SOFR Loans.

Under the Current Facility, interest on the 5-year Term Loan is charged at a fixed rate of 2.96% and is payable on the first day of each calendar quarter. Interest on SOFR Loans is charged at an adjusted SOFR rate and is payable (i) on the last day of the interest period in effect, (ii) in the event such interest period shall exceed three months, on the last day of each three month interval during such interest period and (iii) the termination date. Interest on Base Rate Loans is charged at a rate equal to the highest of (i) Term SOFR; (ii) the Overnight Bank Funding Rate; and (iii) the federal funds rate as in effect on that day, plus a spread, and is payable (i) with respect to interest accrued during a calendar month, on the fifteenth day of the immediately succeeding calendar month, and (ii) with respect to all accrued and unpaid interest, on the termination date.

During the six months ended April 30, 2023, the average principal balance outstanding and average annualized interest rate were $60,000,000 and 4.09%, respectively. At April 30, 2023, the principal balance outstanding under the Current Facility was $60 million, consisting of the $30 million 5-year Term Loan and $30 million outstanding under the revolving credit facility.

The Fund pays a commitment fee in arrears based on the unused portion of the revolving commitment amount under the Current Facility. This fee is included in the Interest expense line item that is reflected in the Statement of Operations. Under the terms of the Current Facility, the Fund is required to satisfy certain collateral requirements and maintain a certain level of net assets.

Concentration of risk: Under normal market conditions, the Fund’s investments will be concentrated in income producing common equity securities, preferred securities, convertible securities and non-convertible debt securities issued by companies deriving the majority of their revenue from the ownership, construction, financing, management and/or sale of commercial, industrial, and/or residential real estate. The value and/or price of the Fund’s common stock may fluctuate more due to economic, legal, cultural, geopolitical or technological developments affecting the United States real estate industry, or a segment of the United States real estate industry in which the Fund owns a substantial position, than would the stock of a fund not concentrated in the real estate industry.

Securities lending: The Fund, using State Street as its lending agent, may loan securities to qualified brokers and dealers in exchange for negotiated lender’s fees. These fees, if any, would be disclosed within the Statement of Operations under the caption "Income from securities loaned-net" and are net of expenses retained by State Street as compensation for its services as lending agent.

The initial collateral received by the Fund at the beginning of each transaction shall have a value equal to at least 102% of the prior day’s market value of the loaned securities (105% in the case of international

securities). Collateral in the form of cash and/or securities issued or guaranteed by the U.S. government or its agencies, equivalent to at least 100% of the market value of securities, is maintained at all times. Thereafter, the value of the collateral is monitored on a daily basis, and collateral is moved daily between a counterparty and the Fund until the close of the transaction. Cash collateral is generally invested in a money market fund registered under the 1940 Act that is managed by an affiliate of State Street and is included in the Statement of Assets and Liabilities under the caption "Investments in securities, at value-Unaffiliated issuers". The total value of securities received as collateral for securities on loan is included in a footnote following the Schedule of Investments, but is not included within the Statement of Assets and Liabilities because the receiving Fund does not have the right to sell or repledge the securities received as collateral. The risks associated with lending portfolio securities include, but are not limited to, possible delays in receiving additional collateral or in the recovery of the loaned securities. Any increase or decrease in the fair value of the securities loaned and any interest earned or dividends paid or owed on those securities during the term of the loan would accrue to the Fund.

During the six months ended April 30, 2023, the Fund did not participate in securities lending.

Indemnifications: Like many other companies, the Fund’s organizational documents provide that its officers ("Officers") and directors ("Directors") are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, both in some of its principal service contracts and in the normal course of its business, the Fund enters into contracts that provide indemnifications to other parties for certain types of losses or liabilities. The Fund’s maximum exposure under these arrangements is unknown as this could involve future claims against the Fund.

Note B—Investment Management Fees, Administration Fees, and Other Transactions with Affiliates:

The Fund retains NBIA as its investment manager under a Management Agreement. For such investment management services, the Fund pays NBIA an investment management fee at an annual rate of 0.60% of the Fund's average daily Managed Assets. Managed Assets equal the total assets of the Fund, less liabilities other than the aggregate indebtedness entered into for purposes of leverage.

The Fund retains NBIA as its administrator under an Administration Agreement. The Fund pays NBIA an administration fee at an annual rate of 0.25% of its average daily Managed Assets under this agreement. Additionally, NBIA retains State Street as its sub-administrator under a Sub-Administration Agreement. NBIA pays State Street a fee for all services received under the Sub-Administration Agreement.

Note C—Securities Transactions:

During the six months ended April 30, 2023, there were purchase and sale transactions of long-term securities of $6,851,739 and $20,562,881, respectively.

During the six months ended April 30, 2023, no brokerage commissions on securities transactions were paid to affiliated brokers.

Note D—Capital:

Transactions in shares of common stock six months ended April 30, 2023, and for the year ended October 31, 2022, were as follows:

For the Six Months Ended April 30, 2023		For the Year Ended October 31, 2022

Note E—Recent Accounting Pronouncements:

In December 2022, the FASB issued Accounting Standards Update No. 2022-06, "Reference Rate Reform (Topic 848)" ("ASU 2022-06"), which is an update to Accounting Standards Update No. 2021-01, "Reference Rate Reform (Topic 848)" ("ASU 2021-01") and defers the sunset date for applying the reference rate reform relief in Topic 848. ASU 2021-01 is an update of ASU 2020-04, which is in response to concerns about structural risks of interbank offered rates, and particularly the risk of cessation of LIBOR. Regulators have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction based and less susceptible to manipulation. ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The ASU 2021-01 update clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The amendments in this update are effective immediately through December 31, 2024, for all entities. Management is currently evaluating the implications, if any, of the additional requirements and its impact on the Fund's financial statements.

In June 2022, FASB issued Accounting Standards Update No. 2022-03, "Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions" ("ASU 2022-03"). ASU 2022-03 clarifies the guidance in ASC 820, related to the measurement of the fair value of an equity security subject to contractual sale restrictions, where it eliminates the ability to apply a discount to the fair value of these securities, and introduces disclosure requirements related to such equity securities. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, and allows for early adoption. Management is currently evaluating the impact of applying this update.

a	Calculated based on the average number of shares of common stock outstanding during each fiscal period.
b	Total return based on per share NAV reflects the effects of changes in NAV on the performance of the Fund during each fiscal period. Total return based on per share market value assumes the purchase of shares of common stock at the market price on the first day and sale of common stock at the market price on the last day of the period indicated. Distributions, if any, are assumed to be reinvested at prices obtained under the Fund's distribution reinvestment plan. Results represent past performance and do not indicate future results. Current returns may be lower or higher than the performance data quoted. Investment returns will fluctuate and shares of common stock, when sold, may be worth more or less than original cost.
c	Not annualized.
d	Had the Fund not received class action proceeds in 2021, total return based on per share NAV for the year ended October 31, 2021 would have been 45.59%.
e	Interest expense is included in expense ratios. The annualized ratios of interest expense to average net assets applicable to common stockholders were:

Six Months Ended April 30, 2023	Year Ended October 31,
	2022	2021	2020	2019	2018
1.48%	0.76%	0.48%	0.92%	1.39%	1.51%

f	Annualized.
g	Net of unamortized deferred issuance costs. The unamortized deferred issuance costs for the year ended October 31, 2018 were $30,482.
h	Calculated by subtracting the Fund’s total liabilities (excluding loans payable and accumulated unpaid interest on loans payable) from the Fund’s total assets and dividing by the outstanding loans payable balance.

Distribution Reinvestment Plan for the Fund

American Stock Transfer & Trust Company, LLC (the "Plan Agent") will act as Plan Agent for stockholders who have not elected in writing to receive dividends and distributions in cash (each a "Participant"), will open an account for each Participant under the Distribution Reinvestment Plan ("Plan") in the same name as their then-current shares of the Fund’s common stock ("Shares") are registered, and will put the Plan into effect for each Participant as of the first record date for a dividend or capital gains distribution.

Whenever the Fund declares a dividend or distribution with respect to the Shares, each Participant will receive such dividends and distributions in additional Shares, including fractional Shares acquired by the Plan Agent and credited to each Participant’s account. If on the payment date for a cash dividend or distribution, the net asset value is equal to or less than the market price per Share plus estimated brokerage commissions, the Plan Agent shall automatically receive such Shares, including fractions, for each Participant’s account. Except in the circumstances described in the next paragraph, the number of additional Shares to be credited to each Participant’s account shall be determined by dividing the dollar amount of the dividend or distribution payable on their Shares by the greater of the net asset value per Share determined as of the date of purchase or 95% of the then-current market price per Share on the payment date.

Should the net asset value per Share exceed the market price per Share plus estimated brokerage commissions on the payment date for a cash dividend or distribution, the Plan Agent or a broker-dealer selected by the Plan Agent shall endeavor, for a purchase period lasting until the last business day before the next date on which the Shares trade on an "ex-dividend" basis, but in no event, except as provided below, more than 30 days after the payment date, to apply the amount of such dividend or distribution on each Participant’s Shares (less their pro rata share of brokerage commissions incurred with respect to the Plan Agent’s open-market purchases in connection with the reinvestment of such dividend or distribution) to purchase Shares on the open market for each Participant’s account. No such purchases may be made more than 30 days after the payment date for such dividend or distribution except where temporary curtailment or suspension of purchase is necessary to comply with applicable provisions of federal securities laws. If, at the close of business on any day during the purchase period the net asset value per Share equals or is less than the market price per Share plus estimated brokerage commissions, the Plan Agent will not make any further open-market purchases in connection with the reinvestment of such dividend or distribution. If the Plan Agent is unable to invest the full dividend or distribution amount through open-market purchases during the purchase period, the Plan Agent shall request that, with respect to the uninvested portion of such dividend or distribution amount, the Fund issue new Shares at the close of business on the earlier of the last day of the purchase period or the first day during the purchase period on which the net asset value per Share equals or is less than the market price per Share, plus estimated brokerage commissions, such Shares to be issued in accordance with the terms specified in the third paragraph hereof. These newly issued Shares will be valued at the then-current market price per Share at the time such Shares are to be issued.

For purposes of making the reinvestment purchase comparison under the Plan, (a) the market price of the Shares on a particular date shall be the last sales price on the New York Stock Exchange (or if the Shares are not listed on the New York Stock Exchange, such other exchange on which the Shares are principally traded) on that date, or, if there is no sale on such Exchange (or if not so listed, in the over-the-counter market) on that date, then the mean between the closing bid and asked quotations for such Shares on such Exchange on such date and (b) the net asset value per Share on a particular date shall be the net asset value per Share most recently calculated by or on behalf of the Fund. All dividends, distributions and other payments (whether made in cash or Shares) shall be made net of any applicable withholding tax.

Open-market purchases provided for above may be made on any securities exchange where the Fund’s Shares are traded, in the over-the-counter market or in negotiated transactions and may be on such terms as to price, delivery and otherwise as the Plan Agent shall determine. Each Participant’s uninvested funds held by the Plan Agent will not bear interest, and it is understood that, in any event, the Plan Agent shall have no liability in

connection with any inability to purchase Shares within 30 days after the initial date of such purchase as herein provided, or with the timing of any purchases effected. The Plan Agent shall have no responsibility as to the value of the Shares acquired for each Participant’s account. For the purpose of cash investments, the Plan Agent may commingle each Participant’s funds with those of other stockholders of the Fund for whom the Plan Agent similarly acts as agent, and the average price (including brokerage commissions) of all Shares purchased by the Plan Agent as Plan Agent shall be the price per Share allocable to each Participant in connection therewith.

The Plan Agent may hold each Participant’s Shares acquired pursuant to the Plan together with the Shares of other stockholders of the Fund acquired pursuant to the Plan in noncertificated form in the Plan Agent’s name or that of the Plan Agent’s nominee. The Plan Agent will forward to each Participant any proxy solicitation material and will vote any Shares so held for each Participant only in accordance with the instructions set forth on proxies returned by the Participant to the Fund.

The Plan Agent will confirm to each Participant each acquisition made for their account as soon as practicable but not later than 60 days after the date thereof. Although each Participant may from time to time have an undivided fractional interest (computed to three decimal places) in a Share, no certificates for a fractional Share will be issued. However, dividends and distributions on fractional Shares will be credited to each Participant’s account. In the event of termination of a Participant’s account under the Plan, the Plan Agent will adjust for any such undivided fractional interest in cash at the market value of the Shares at the time of termination, less the pro rata expense of any sale required to make such an adjustment.

Any Share dividends or split Shares distributed by the Fund on Shares held by the Plan Agent for Participants will be credited to their accounts. In the event that the Fund makes available to its stockholders rights to purchase additional Shares or other securities, the Shares held for each Participant under the Plan will be added to other Shares held by the Participant in calculating the number of rights to be issued to each Participant.

The Plan Agent’s service fee for handling capital gains and other distributions or income dividends will be paid by the Fund. Participants will be charged their pro rata share of brokerage commissions on all open-market purchases.

Each Participant may terminate their account under the Plan by notifying the Plan Agent in writing. Such termination will be effective immediately if the Participant’s notice is received by the Plan Agent not less than ten days prior to any dividend or distribution record date, otherwise such termination will be effective the first trading day after the payment date for such dividend or distribution with respect to any subsequent dividend or distribution. The Plan may be terminated by the Plan Agent or the Fund upon notice in writing mailed to each Participant at least 30 days prior to any record date for the payment of any dividend or distribution by the Fund.

These terms and conditions may be amended or supplemented by the Plan Agent or the Fund at any time or times but, except when necessary or appropriate to comply with applicable law or the rules or policies of the Securities and Exchange Commission or any other regulatory authority, only by mailing to each Participant appropriate written notice at least 30 days prior to the effective date thereof. The amendment or supplement shall be deemed to be accepted by each Participant unless, prior to the effective date thereof, the Plan Agent receives written notice of the termination of their account under the Plan. Any such amendment may include an appointment by the Plan Agent in its place and stead of a successor Plan Agent under these terms and conditions, with full power and authority to perform all or any of the acts to be performed by the Plan Agent under these terms and conditions. Upon any such appointment of any Plan Agent for the purpose of receiving dividends and distributions, the Fund will be authorized to pay to such successor Plan Agent, for each Participant’s account, all dividends and distributions payable on Shares held in their name or under the Plan for retention or application by such successor Plan Agent as provided in these terms and conditions.

The Plan Agent shall at all times act in good faith and agrees to use its best efforts within reasonable limits to ensure the accuracy of all services performed under this Agreement and to comply with applicable law, but assumes no responsibility and shall not be liable for loss or damage due to errors unless such error is caused by

the Plan Agent’s negligence, bad faith, or willful misconduct or that of its employees. These terms and conditions are governed by the laws of the State of Maryland.

Reinvested dividends and distributions are taxed in the same manner as cash dividends and distributions — i.e., reinvestment in additional Shares does not relieve stockholders of, or defer the need to pay, any income tax that may be payable (or that is required to be withheld) on Fund dividends and distributions. Participants should contact their tax professionals for information on how the Plan impacts their personal tax situation. For additional information about the Plan, please contact the Plan Agent by telephone at 1-866-227-2136 or by mail at 6201 15th Avenue, Brooklyn, NY, 11219 or online at www.astfinancial.com.
