Beginning on January 1, 2021, as permitted by regulations adopted by the U.S. Securities and Exchange Commission, paper copies of the Fund’s annual and semi-annual shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports. Instead, the reports will be made available on the Fund’s website at www.RiverNorth.com and you will be notified by mail each time a report is posted and provided with a website link to access the report.

You may, notwithstanding the availability of shareholder reports online, elect to receive all future shareholder reports in paper free of charge.

If you invest directly with a Fund, you can call 1-888-848-7569 to let the Fund know you wish to continue receiving paper copies of your shareholder reports.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. You may elect to receive shareholder reports and other communications from the Fund electronically anytime by contacting your financial intermediary (such as a broker-dealer or bank) or, if you are a direct investor, by enrolling at www.RiverNorth.com.

Performance Overview December 31, 2020 (Unaudited)

WHAT IS THE FUND’S INVESTMENT STRATEGY?

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc. (the "Fund") seeks to achieve its investment objective by allocating its Managed Assets among the two principal investment strategies described below:

Tactical Closed-End Fund Income Strategy (10% - 35% of Managed Assets): This strategy seeks to (i) generate returns through investments in closed-end funds, exchange-traded funds and business development companies (collectively, the “Underlying Funds”) that invest primarily in income-producing securities, and (ii) derive value from the discount and premium spreads associated with closed-end funds.

Opportunistic Income Strategy (65% - 90% of Managed Assets): This strategy seeks to generate attractive risk-adjusted returns through investments in fixed income instruments and other investments, including agency and non-agency residential mortgage-backed and other asset-backed securities, corporate bonds, municipal bonds, and real estate investment trusts. At least 50% of the Managed Assets allocated to this strategy is invested in mortgage-backed securities.

Notes to Financial Statements December 31, 2020 (Unaudited)

1.  ORGANIZATION

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc. (the “Fund”) is a closed-end management investment company that was organized as a Maryland corporation on June 22, 2016, and commenced investment operations on September 28, 2016. The investment adviser to the Fund is RiverNorth Capital Management, LLC (the “Adviser”). The Fund’s sub-adviser is DoubleLine Capital, LP (“Sub-Adviser”). The Fund is a diversified investment company with an investment objective to seek current income and overall total return.

The Fund seeks to achieve its investment objective by allocating its Managed Assets among two principal strategies; under normal market conditions, the Fund may allocate between 10% and 35% of its Managed Assets to the Tactical Closed-End Fund Income Strategy and 65% to 90% of its Managed Assets to the Opportunistic Income Strategy. The Adviser will determine the portion of the Fund’s Managed Assets to allocate to each strategy and may, from time to time, adjust the allocations.

2.  SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the Fund. These policies are in conformity with generally accepted accounting principles in the United States of America (“GAAP”). The financial statements are prepared in accordance with GAAP, which requires management to make estimates and assumptions that affect the reported amounts and disclosures, including the disclosure of contingent assets and liabilities, in the financial statements during the reporting period. Management believes the estimates and security valuations are appropriate; however, actual results may differ from those estimates, and the security valuations reflected in the financial statements may differ from the value the Fund ultimately realizes upon sale of the securities. The Fund is considered an investment company for financial reporting purposes under GAAP and follows the accounting and reporting guidance applicable to investment companies as codified in Accounting Standards Codification (“ASC”) 946 – Investment Companies. The financial statements have been prepared as of the close of the New York Stock Exchange (“NYSE”) on December 31, 2020.

Security Valuation: The Fund’s investments are generally valued at their fair value using market quotations. If a market value quotation is unavailable a security may be valued at its estimated fair value as described in Note 3.

Security Transactions and Related Income: The Fund follows industry practice and records security transactions on the trade date basis. The specific identification method is used for determining gains or losses for financial statements and income tax purposes. Dividend income is recorded on the ex-dividend date or for certain foreign securities, when the information becomes available to the Fund and interest income and expenses are recorded on an accrual basis. Discounts and premiums on securities purchased are amortized or accreted using the effective interest method. Paydown gains and losses on mortgage-related and other asset-backed securities are recorded as components of interest income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules and rates. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country or region. Settlement on bank loans transactions may be in excess of seven business days. Interest only stripped mortgage backed securities (“IO Strips”) are securities that receive only interest payments from a pool of mortgage loans. Little to no principal will be received by the Fund upon maturity of an IO Strip. Periodic adjustments are recorded to reduce the cost of the security until maturity, which are included in interest income.

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.

Notes to Financial Statements December 31, 2020 (Unaudited)

Foreign Currency Translation: The books and records of the Funds are maintained in U.S. dollars. Investment valuations and other assets and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Prevailing foreign exchange rates may generally be obtained at the close of the NYSE (normally, 4:00 p.m. Eastern time). The portion of realized and unrealized gains or losses on investments due to fluctuations in foreign currency exchange rates is not separately disclosed and is included in realized and unrealized gains or losses on investments, when applicable.

Preferred Stock: The Company carries its mandatorily redeemable preferred stock at accreted cost on the Statement of Assets and Liabilities, and not fair value. Refer to “Note 8. Redeemable Preferred Stock” for further details. In accordance with ASC 480-10-25, the Company's redeemable preferred stock has been classified as a liability on the Statement of Assets and Liabilities. Dividend payments relating to the redeemable preferred stock are included in preferred dividend payable on the Statement of Assets and Liabilities and preferred dividend expense on the Statement of Operations. Issuance costs are amortized and included in interest expense in the Fund's Statement of Operations. Upon early termination of preferred stock, the remaining balance of unamortized fees related to such debt is accelerated into realized gain/loss on preferred stock on the Statement of Operations. Deferred issuance costs are included on the Statement of Assets and Liabilities as a reduction to Series A Cumulative Preferred Stock.

Other: The Fund holds certain investments which pay dividends to their shareholders based upon available funds from operations. It is possible for these dividends to exceed the underlying investments’ taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. Distributions received from investments in securities that represent a return of capital or long-term capital gains are recorded as a reduction of the cost of investments or as a realized gain, respectively.

Share Valuation: The NAV is generally calculated as of the close of trading on the New York Stock Exchange (“the Exchange”) (normally 4:00 p.m. Eastern time) every day the Exchange is open. The NAV is calculated by dividing the value of all of the securities and other assets of the Fund, less the liabilities (including accrued expenses and indebtedness), by the total number of common shares outstanding.

Federal Income Taxes: The Fund has been treated as, and intends to qualify each year for special tax treatment afforded to, a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code, as amended (“IRC”). In order to qualify as a RIC, the Fund must, among other things, satisfy income, asset diversification and distribution requirements. As long as it so qualifies, the Fund will not be subject to U.S. federal income tax to the extent that it distributes annually its investment company taxable income and its “net capital gain”. If the Fund retains any investment company taxable income or net capital gain, it will be subject to U.S. federal income tax on the retained amount at regular corporate tax rates. In addition, if the Fund fails to qualify as a RIC for any taxable year, it will be subject to U.S. federal income tax on all of its income and gains at regular corporate tax rates.

Notes to Financial Statements December 31, 2020 (Unaudited)

Distributions to Shareholders: Distributions to shareholders, which are determined in accordance with income tax regulations, are recorded on the ex-dividend date. The treatment for financial reporting purposes of distributions made to shareholders during the year from net investment income or net realized capital gains may differ from their ultimate treatment for federal income tax purposes. These differences are caused primarily by differences in the timing of recognition of certain components of income, expense, or realized capital gain for federal income tax purposes. Where such differences are permanent in nature, they are reclassified in the components of the net assets based on their ultimate characterization for federal income tax purposes. Any such reclassification will have no effect on net assets, results of operations, or net asset values per share of the Fund.

The Fund maintains a level distribution policy. The Fund distributes to shareholders regular monthly cash distributions of its net investment income. In addition, the Fund distributes its net realized capital gains, if any, at least annually.

At times, to maintain a stable level of distributions, the Fund may pay out less than all of its net investment income or pay out accumulated undistributed income, or return of capital, in addition to current net investment income. Any distribution that is treated as a return of capital generally will reduce a shareholder’s basis in his or her shares, which may increase the capital gain or reduce the capital loss realized upon the sale of such shares. Any amounts received in excess of a shareholder’s basis are generally treated as capital gain, assuming the shares are held as capital assets.

The Board approved the implementation of the level distribution policy to make monthly cash distributions to common shareholders, stated in terms of a rate equal to 12.5% of the average of the Fund’s NAV per share for the final five trading days of the previous calendar year. The Fund made monthly distributions to common shareholders set at a level monthly rate of $0.18 per common share for the period ended December 31, 2020.

Previously, the Board approved the adoption of a managed distribution plan in accordance with a Section 19(b) exemptive order whereby the Fund made monthly distributions to common shareholders set at a fixed monthly rate of $0.15 per common share.

The amount of the Fund’s distributions pursuant to the managed distribution plan are not related to the Fund’s performance and, therefore, investors should not make any conclusions about the Fund’s investment performance from the amount of the Fund’s distributions or from the terms of the Fund’s managed distribution plan. The Board may amend, suspend or terminate the managed distribution plan at any time without notice to shareholders.

Distributions to holders of redeemable preferred stock are accrued on a daily basis as described in Note 8 and are treated as an operating expense as required by U.S. GAAP. For tax purposes, the payments made to the holders of the Fund’s redeemable preferred stock are treated as dividends or distributions. The character of distributions to the holders of the Fund's redeemable preferred stock made during the year may differ from their ultimate characterization for federal income tax purposes.

3.  SECURITIES VALUATION AND FAIR VALUE MEASUREMENTS

Fair value is defined as the price that the Fund might reasonably expect to receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. GAAP establishes a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes.

Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value including using such a pricing model and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in the three broad levels listed below.

Level 1 – Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities that a Fund has the ability to access at the measurement date;

Level 2 – Quoted prices which are not active, quoted prices for similar assets or liabilities in active markets or inputs other than quoted prices that are observable (either directly or indirectly) for substantially the full term of the asset or liability; and

Level 3 – Significant unobservable prices or inputs (including the Fund’s own assumptions in determining the fair value of investments) where there is little or no market activity for the asset or liability at the measurement date.

The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Equity securities, including closed-end funds and business development company notes, are generally valued by using market quotations, but may be valued on the basis of prices furnished by a pricing service when the Adviser or the Sub-Adviser believes such prices more accurately reflect the fair market value of such securities. Securities that are traded on any stock exchange are generally valued by the pricing service at the last quoted sale price. Lacking a last sale price, an exchange traded security is generally valued by the pricing service at its last bid price. Securities traded in the NASDAQ over-the-counter market are generally valued by the pricing service at the NASDAQ Official Closing Price. When using the market quotations or close prices provided by the pricing service and when the market is considered active, the security will be classified as a Level 1 security. Sometimes, an equity security owned by the Fund will be valued by the pricing service with factors other than market quotations or when the market is considered inactive. When this happens, the security will be classified as a Level 2 security. When market quotations are not readily available, when the Adviser or the Sub-Adviser determines that the market quotation or the price provided by the pricing service does not accurately reflect the current fair value, or when restricted or illiquid securities are being valued, such securities are valued as determined in good faith by the Adviser, Sub-Adviser, or Valuation Committee in conformity with guidelines adopted by and subject to review by the Board. These securities will be categorized as Level 3 securities.

Notes to Financial Statements December 31, 2020 (Unaudited)

Investments in mutual funds, including short term investments, are generally priced at the ending NAV provided by the service agent of the funds. These securities will be classified as Level 1 securities.

Domestic and foreign fixed income securities, including foreign and U.S. corporate bonds, foreign government bonds and notes, supranationals and foreign agencies, asset backed obligations, non-agency collateralized mortgage obligations, U.S. Government/Agency mortgage backed securities, bank loans, and collateralized loan obligations are normally valued on the basis of quotes obtained from brokers and dealers or independent pricing services. Foreign currency positions, including forward foreign currency contracts, are priced at the mean between the closing bid and asked prices at 4:00 p.m. Eastern Time. Prices obtained from independent pricing services typically use information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Data used to establish quotes includes analysis of cash flows , pre-payment speeds, default rates, delinquency assumptions and assumptions regarding collateral and loss assumptions. These securities will be classified as Level 2 securities.

Short-term investments in fixed income securities, excluding money market funds, with maturities of less than 60 days when acquired, or which subsequently are within 60 days of maturity, are valued by using the amortized cost method of valuation, which the Board has determined will represent fair value. These securities will be classified as Level 2 securities.

In accordance with the Fund’s good faith pricing guidelines, the Adviser, Sub-Adviser, or Valuation Committee is required to consider all appropriate factors relevant to the value of securities for which it has determined other pricing sources are not available or reliable as described above. No single standard exists for determining fair value, because fair value depends upon the circumstances of each individual case. As a general principle, the current fair value of an issue of securities being valued by the Adviser, Sub-Adviser, or valuation committee would appear to be the amount which the owner might reasonably expect to receive for them upon their current sale. Methods which are in accordance with this principle may, for example, be based on (i) a multiple of earnings; (ii) discounted cash flow models; (iii) weighted average cost or weighted average price; (iv) a discount from market of a similar freely traded security (including a derivative security or a basket of securities traded on other markets, exchanges or among dealers); or (v) yield to maturity with respect to debt issues, or a combination of these and other methods. Good faith pricing is permitted if, in the Adviser’s, a Sub-Adviser’s, or the Valuation Committee’s opinion, the validity of market quotations appears to be questionable based on factors such as evidence of a thin market in the security based on a small number of quotations, a significant event occurs after the close of a market but before a Fund’s NAV calculation that may affect a security’s value, or the Adviser or a Sub-Adviser is aware of any other data that calls into question the reliability of market quotations.

Good faith pricing may also be used in instances when the bonds in which the Fund invests default or otherwise cease to have market quotations readily available.

5.  FEDERAL INCOME TAXES

It is the Fund’s policy to meet the requirements of the IRC applicable to regulated investment companies, and to distribute all of its taxable net income to its shareholders. In addition, the Fund intends to pay distributions as required to avoid imposition of excise tax. Therefore, no federal income tax provision is required.

Tax Basis of Distributions to Shareholders: The character of distributions made during the year from net investment income or net realized gains may differ from its ultimate characterization for federal income tax purposes. Also, due to the timing of dividend distributions, the fiscal year in which amounts are distributed may differ from the fiscal year in which the income or realized gains were recorded by the Fund.

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.

Notes to Financial Statements December 31, 2020 (Unaudited)

The tax character of the distributions paid by the Fund during the fiscal years ended June 30, 2020, was as follows:

	June 30, 2020
Ordinary Income	$	12,194,880
Return of Capital		14,373,741
Total	$	26,568,621

Unrealized Appreciation and Depreciation on Investments: As of December 31, 2020, net unrealized appreciation/(depreciation) of investments based on federal tax costs was as follows:

Cost of investments for income tax purposes	$	305,165,620
Gross appreciation on investments (excess of value over tax cost)		11,381,659
Gross depreciation on investments (excess of tax cost over value)		(17,433,797	)
Net unrealized depreciation on investments	$	(6,052,138	)

The difference between book and tax basis unrealized appreciation/(depreciation) for the Fund is primarily attributable to wash sales.

The Fund recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. Management has analyzed the Fund’s tax positions, and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on U.S. tax returns and state tax returns filed since inception of the Fund. No income tax returns are currently under examination. All tax years since commencement of operations remain subject to examination by the tax authorities in the United States. The Fund is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

6.  INVESTMENT TRANSACTIONS

Investment transactions for the period ended December 31, 2020, excluding short-term investments, were as follows:

Purchases	Sales
$58,024,115	$36,111,952

7.  REVOLVING CREDIT FACILITY

The Fund may borrow money and/or issue preferred stock, notes or debt securities for investment purposes. These practices are known as leveraging. The Fund may use leverage through borrowings or the issuance of preferred stock, in an aggregate amount of up to 33 1/3% of the Fund’s Total Assets immediately after such borrowings or issuance.

8.  REDEEMABLE PREFERRED STOCK

At December 31, 2020, the Fund had issued and outstanding 2,400,000 shares of Series A Preferred Stock, listed under trading symbol OPPPRA on the NYSE, with a par value of $0.0001 per share and a liquidation preference of $25.00 per share plus accrued and unpaid dividends (whether or not declared). The Fund issued 2,400,000 shares of Series A Preferred Stock on October 23, 2020. The Series A Preferred Stock is entitled to a dividend at a rate of 4.375% per year, paid quarterly, based on the $25.00 liquidation preference before the common stock is entitled to receive any dividends. The Series A Preferred Stock is generally not redeemable at the Fund’s option prior to November 15, 2025, and is subject to mandatory redemption by the Fund in certain circumstances. On or after November 15, 2025, the Fund may redeem in whole, or from time to time in part, outstanding Series A Preferred Stock at a redemption price per share equal to the per share liquidation preference of $25.00 per share, plus accumulated and unpaid dividends, if any, through the date of redemption. Issuance costs related to Series A Preferred Stock of $1,890,000 are deferred and amortized over the period the Series A Preferred Stock is outstanding.

Series	First Redemption Date	Fixed Rate	Shares Outstanding	Aggregate Liquidation Preference	Estimated Fair Value
Series A	November 15, 2025	4.375%	2,400,000	$ 60,000,000	$ 59,952,000

9.  CAPITAL SHARE TRANSACTIONS

The Fund’s authorized capital stock consists of 50,000,000 shares of common stock, $0.0001 par value per share, all of which is initially classified as common shares. Under the rules of the NYSE applicable to listed companies, the Fund is required to hold an annual meeting of stockholders in each year.

On November 1, 2019 and August 12-13, 2020, the Board approved rights two offerings to participating shareholders of record who were allowed to subscribe for new common shares of the Fund (the “Primary Subscription”). Record Date Shareholders received one right for each common share held on the Record Date ("Right"). For every three Rights held, a holder of the Rights was entitled to buy one new common share of the Fund. Record Date Shareholders who fully exercised all Rights initially issued to them in the Primary Subscription were entitled to buy those common shares that were not purchased by other Record Date Shareholders. The Fund issued new shares of common stock at a subscription price that represented 92.5% of the reported net asset value on the expiration date of each rights offering. Offering costs were charged to paid-in-capital upon the exercise of the Rights.

Additional shares of the Fund may be issued under certain circumstances, including pursuant to the Fund’s Automatic Dividend Reinvestment Plan, as defined within the Fund’s organizational documents. Additional information concerning the Automatic Dividend Reinvestment Plan is included within this report.

10. INDEMNIFICATIONS

Under the Fund’s organizational documents, its officers and Directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that may contain general indemnification clauses. The Fund’s maximum exposure under those arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred.

11. CORONAVIRUS (COVID-19) PANDEMIC

A recent outbreak of respiratory disease caused by a novel coronavirus was first detected in December 2019 and has spread internationally. The outbreak and efforts to contain its spread have resulted in closing borders and quarantines, restricting international and domestic travel, enhanced health screenings, cancelations, disrupted supply chains and customer activity, responses by businesses (including changes to operations and reducing staff), and have produced general concern and uncertainty. The impact of the coronavirus pandemic, and other epidemics and pandemics that may arise in the future could adversely affect national and global economies, individual companies and the market in general in a manner and for a period of time that cannot be foreseen at the present time and may adversely affect the value, volatility and liquidity of dividend and interest paying securities. In the event of a pandemic or an outbreak, there can be no assurance that the Fund and its service providers will be able to maintain normal business operations for an extended period of time or will not lose the services of key personnel on a temporary or long-term basis due to illness or other reasons, and could otherwise disrupt the ability of the Fund's service providers to perform essential services. Certain economic and market conditions arising out of a pandemic or outbreak could result in a Fund's inability to achieve its investment objectives, cause the postponement of reconstitution or rebalance dates for benchmark indices, adversely affect the prices and liquidity of the securities and other instruments in which a Fund invests, negatively impact a Fund's performance, and cause losses on your investment in a Fund. Management is monitoring the development of the pandemic, which was ongoing as of the date of the financial statements, and is evaluating its impact on the financial position and operating results of the Fund.

12. LIBOR TRANSITION

Certain of the Fund's investments, payment obligations and financing terms may be based on floating rates, such as LIBOR, Euro Interbank Offered Rate and other similar types of reference rates (each, a “Reference Rate”). On July 27, 2017, the Chief Executive of the UK Financial Conduct Authority (“FCA”), which regulates LIBOR, announced that the FCA will no longer persuade nor compel banks to submit rates for the calculation of LIBOR and certain other Reference Rates after 2021. Such announcement indicates that the continuation of LIBOR and other Reference Rates on the current basis cannot and will not be guaranteed after 2021. The transition away from Reference Rates may lead to increased volatility and illiquidity in markets that are tied to such Reference Rates and reduced values of Reference Rate-related instruments. This announcement and any additional regulatory or market changes that occur as a result of the transition away from Reference Rates may have an adverse impact on a Fund’s investments, performance or financial condition.

13. SUBSEQUENT EVENTS

Subsequent to December 31, 2020, the Fund paid the following distributions:

Dividend Reinvestment Plan December 31, 2020 (Unaudited)

The Fund has an automatic dividend reinvestment plan commonly referred to as an “opt-out” plan. Unless the registered owner of Common Shares elects to receive cash by contacting DST Systems, Inc. (the “Plan Administrator”), all dividends declared on Common Shares will be automatically reinvested by the Plan Administrator for shareholders in the Fund’s Automatic Dividend Reinvestment Plan (the “Plan”), in additional Common Shares. Common Shareholders who elect not to participate in the Plan will receive all dividends and other distributions in cash paid by check mailed directly to the shareholder of record (or, if the Common Shares are held in street or other nominee name, then to such nominee) by the Plan Administrator as dividend disbursing agent. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notice if received and processed by the Plan Administrator prior to the dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Such notice will be effective with respect to a particular dividend or other distribution (together, a “Dividend”). Some brokers may automatically elect to receive cash on behalf of Common Shareholders and may re-invest that cash in additional Common Shares. Reinvested Dividends will increase the Fund’s Managed Assets on which the management fee is payable to the Adviser (and by the Adviser to the Sub-Adviser).

Whenever the Fund declares a Dividend payable in cash, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in Common Shares. The Common Shares will be acquired by the Plan Administrator for the participants’ accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized Common Shares from the Fund (“Newly Issued Common Shares”) or (ii) by purchase of outstanding Common Shares on the open market (“Open-Market Purchases”) on the NYSE or elsewhere. If, on the payment date for any Dividend, the closing market price plus estimated brokerage commissions per Common Share is equal to or greater than the NAV per Common Share, the Plan Administrator will invest the Dividend amount in Newly Issued Common Shares on behalf of the participants. The number of Newly Issued Common Shares to be credited to each participant’s account will be determined by dividing the dollar amount of the Dividend by the Fund’s NAV per Common Share on the payment date. If, on the payment date for any Dividend, the NAV per Common Share is greater than the closing market value plus estimated brokerage commissions (i.e., the Fund’s Common Shares are trading at a discount), the Plan Administrator will invest the Dividend amount in Common Shares acquired on behalf of the participants in Open-Market Purchases.

In the event of a market discount on the payment date for any Dividend, the Plan Administrator will have until the last business day before the next date on which the Common Shares trade on an “ex-dividend” basis or 30 days after the payment date for such Dividend, whichever is sooner (the “Last Purchase Date”), to invest the Dividend amount in Common Shares acquired in Open-Market Purchases. It is contemplated that the Fund will pay monthly income Dividends. If, before the Plan Administrator has completed its Open-Market Purchases, the market price per Common Share exceeds the NAV per Common Share, the average per Common Share purchase price paid by the Plan Administrator may exceed the NAV of the Common Shares, resulting in the acquisition of fewer Common Shares than if the Dividend had been paid in Newly Issued Common Shares on the Dividend payment date. Because of the foregoing difficulty with respect to Open-Market Purchases, the Plan provides that if the Plan Administrator is unable to invest the full Dividend amount in Open-Market Purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Administrator may cease making Open-Market Purchases and may invest the uninvested portion of the Dividend amount in Newly Issued Common Shares at the NAV per Common Share at the close of business on the Last Purchase Date.

Dividend Reinvestment Plan December 31, 2020 (Unaudited)

The Plan Administrator maintains all shareholders’ accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Common Shares in the account of each Plan participant will be held by the Plan Administrator on behalf of the Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Plan. The Plan Administrator will forward all proxy solicitation materials to participants and vote proxies for shares held under the Plan in accordance with the instructions of the participants.

Beneficial owners of Common Shares who hold their Common Shares in the name of a broker or nominee should contact the broker or nominee to determine whether and how they may participate in the Plan. In the case of Common Shareholders such as banks, brokers or nominees which hold shares for others who are the beneficial owners, the Plan Administrator will administer the Plan on the basis of the number of Common Shares certified from time to time by the record shareholder’s name and held for the account of beneficial owners who participate in the Plan.

There will be no brokerage charges with respect to Common Shares issued directly by the Fund. However, each participant will pay a pro rata share of brokerage commissions incurred in connection with Open-Market Purchases. The automatic reinvestment of Dividends will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such Dividends, even though such participants have not received any cash with which to pay the resulting tax. See “U.S. Federal Income Tax Matters” below. Participants that request a sale of Common Shares through the Plan Administrator are subject to brokerage commissions.

The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants with regard to purchases in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. All correspondence or questions concerning the Plan should be directed to the Plan Administrator at (844) 569-4750.

Consideration and Approval of Advisory and Sub-Advisory Agreements December 31, 2020 (Unaudited)

Consideration of the Management Agreement

At a meeting (the “Meeting”) of the Board held on November 11, 2020 and called expressly for that purpose, the Board, including a majority of the Directors who are not “interested persons” (as defined in the 1940 Act (the “Independent Directors”)), considered the renewal of the Management Agreement between the Adviser and the Fund.¹ In its consideration of the Management Agreement, the Board considered information and materials furnished by the Adviser in advance of and at the Meeting and was afforded the opportunity to request additional information and to ask questions of the Adviser to obtain information that it believed to be reasonably necessary to evaluate the terms of the Management Agreement. The Board received materials compiled by the Adviser and the Fund’s administrator including a copy of the Management Agreement, the Adviser’s response to a questionnaire regarding the Adviser’s profitability, management and operations, a copy of the Adviser’s Form ADV, and certifications regarding the Adviser’s compliance programs. The Board considered the following factors, among others, in reaching its determination to renew the Management Agreement: (i) the investment performance of the Fund and the investment performance of the Adviser, (ii) the nature, extent and quality of the services provided by the Adviser to the Fund, (iii) the experience and qualifications of the personnel providing such services (iv) the costs of the services provided and the profits to be realized by the Adviser and any of its affiliates from the relationship with the Fund, (v) the extent to which economies of scale will be realized by the Fund as it grows, and (vi) whether the Fund’s fee levels reflected the economies of scale to the benefit of the Fund’s shareholders.

The Directors relied upon the advice of independent legal counsel and their own business judgment in determining the material factors to be considered in evaluating the Management Agreement and the weight to be given to each such factor. The Directors’ conclusions were based on an evaluation of all of the information provided and were not the result of any one factor. Moreover, each Director may have afforded different weight to the various factors in reaching conclusions with respect to the Management Agreement. Although not meant to be all-inclusive, the following discussion summarizes the factors considered and conclusions reached by the Directors at the Meeting, including during an executive session with their independent legal counsel, in determining to renew the Management Agreement.

Performance, Fees and Expenses 

The Board reviewed the performance of the Fund for the three months, one-year, three-year and since inception periods ended September 30, 2020. These returns were compared to the returns of mutual funds in FUSE Research Network, LLC’s (“FUSE”) Multisector Bond fund peer group. The Board noted in its review of the performance that the Fund’s performance was below the median for its peer group for three-month, one-year, three-year and since inception periods. The Directors also noted that the Fund had underperformed its benchmark index for the three-month, one-year, three-year and since-inception periods. The Directors also reviewed the Fund’s performance relative to other funds managed by the Adviser. The Adviser noted the peer group is not entirely reflective of the Fund due to its unique investment structure. In consideration of each item noted, the Board agreed that the Fund’s performance was adequate.

As to the comparative fees and expenses, the Directors considered the management and the other fees paid by the Fund and compared those to the management and other fees paid by funds in the relative peer group determined by FUSE and the Multisector Bond fund universe. The Board noted that the Fund’s annual net expense ratio was higher than the Multisector Bond fund peer group median which the Adviser noted was attributed to the sub-advisory relationship and the uniqueness of the Fund’s investment strategy.

The Board also noted that the annual management fee for the Fund was slightly above the median paid by the peer group but within the range of the fees paid by the peer funds The Directors also reviewed the Fund’s fees relative to other funds managed by the Adviser. The Board, including the Independent Directors, determined that the fees were reasonable given the nature of the Fund’s investment strategy, the capabilities of the Adviser and the Sub-Adviser, and the nature of the services provided to the Fund.

Nature, Extent and Quality of Services

As to the nature, extent and quality of the services to be provided by the Adviser to the Fund, the Board considered that under the terms of the Management Agreement, the Adviser would, subject to the supervision of the Board, provide or arrange to be provided to the Fund such investment advice as the Adviser, in its discretion, deems advisable and will furnish or arrange to be furnished a continuous investment program for the Fund consistent with the Fund’s investment objective and policies. The Board reviewed the Adviser’s Form ADV, which was previously provided to the Board and that provided details regarding the experience of each of the Adviser’s personnel. The Adviser also provided additional information regarding its experience managing other investment accounts. Based on the foregoing information, the Board, including the Independent Directors, concluded that the Adviser had provided quality services and would continue to do so for the Fund.

Profitability and Other Benefits

As to the cost of the services to be provided and to the profits to be realized by the Adviser, the Board reviewed the Adviser’s estimates of its profitability and its financial condition. The Board reviewed the Adviser’s financial statements and noted the Adviser’s financial condition is stable as income from its asset management operations have contributed to higher revenues for the Adviser. The Board acknowledged the Adviser’s management fees were comparable to those charged to other mutual funds to which the Adviser provides advisory or sub-advisory services. It was noted that, when launching a closed-end fund, such as the Fund, RiverNorth covers the underwriting costs, which is a significant investment. The Board, including the Independent Directors, determined that the Management Agreement, with respect to the Fund was not overly profitable to the Adviser and the financial condition of the Adviser was adequate.

The Board noted that the Adviser has no affiliations with the Fund’s transfer agent, fund accountant, custodian, or distributor and therefore does not derive any benefits from the relationships these parties may have with the Fund.

Conclusion

Having requested and received such information from the Adviser as the Board believed to be reasonably necessary to evaluate the terms of the Management Agreement, and as assisted by the advice of independent counsel, the Board, including the Independent Directors, concluded that renewal of the Management Agreement was in the best interests of the Fund and its shareholders.

Consideration and Approval of Advisory and Sub-Advisory Agreements December 31, 2020 (Unaudited)

Consideration of the Sub-Advisory Agreement

At the Meeting, the Board, including the Independent Directors, also considered the renewal of the sub-advisory agreement (the “Sub-Advisory Agreement”) between the Adviser and the Sub-Adviser. In its consideration of the Sub-Advisory Agreement, the Board considered information and materials furnished by the Adviser and the Sub-Adviser in advance of and at the meeting and was afforded the opportunity to request additional information and to ask questions of the Adviser and Sub-Adviser to obtain information that it believed to be reasonably necessary to evaluate the terms of the Sub-Advisory Agreement. The Board received materials compiled by the Sub-Adviser including a copy of the Sub-Advisory Agreement, the Sub-Adviser’s response to a questionnaire regarding its profitability, management and operations, a copy of the Sub-Adviser’s Form ADV, and certifications regarding the Sub-Adviser’s compliance programs. The Board considered the following factors, among others, in reaching its determination to renew the Sub-Advisory Agreement: (i) the investment performance of the Fund and the investment performance of the Sub-Adviser, (ii) the nature, extent and quality of the services provided by Sub-Adviser to the Fund, (iii) the experience and qualifications of the personnel providing such services, (iv) the costs of the services provided and the profits to be realized by the Sub-Adviser and any of its affiliates from the relationship with the Fund, (v) the extent to which economies of scale will be realized by the Fund as it grows, and (vi) whether the fee level of the Fund reflected the economies of scale to the benefit of the Fund’s shareholders.

The Directors relied upon the advice of independent legal counsel and their own business judgment in determining the material factors to be considered in evaluating the Sub-Advisory Agreement and the weight to be given to each such factor. The Directors’ conclusions were based on an evaluation of all of the information provided and were not the result of any one factor. Moreover, each Director may have afforded different weight to the various factors in reaching conclusions with respect to the Sub-Advisory Agreement. Although not meant to be all-inclusive, the following discussion summarizes the factors considered and conclusions reached by the Directors in the executive session and at the Meeting in determining to renew the Sub-Advisory Agreement.

Performance, Fees and Expenses

The Board reviewed the performance of the portion of the Fund managed by the Sub-Adviser relative to relevant securities indices, and to other accounts managed by the Sub-Adviser. The Board recalled its deliberations regarding the Fund’s performance while considering the renewal of the Management Agreement. The Board, including the Independent Directors, concluded that the performance was adequate.

As to the comparative fees and expenses, the Board considered the management fee paid by the Fund to the Adviser and noted that the Adviser pays the Sub-Adviser from its fee, which the Board had previously determined was reasonable. The Board noted that the sub-advisory fee paid by the Adviser to the Sub-Adviser was reasonable as well, given the fees the Sub-Adviser charges other clients to manage similar strategies.

Nature, Extent and Quality of Services

As to the nature, extent and quality of the services to be provided by the Sub-Adviser, the Board considered that under the terms of the Sub-Advisory Agreement, the Sub-Adviser would, subject to the supervision of the Board, provide to the Fund such investment advice as the Sub-Adviser, in its discretion, deems advisable and will furnish or arrange to be furnished a continuous investment program for the Fund consistent with the Fund’s investment objective and policies. The Board reviewed the Form ADV of the Sub-Adviser, which provided details regarding the experience of the Sub-Adviser’s investment personnel. The Sub-Adviser also provided additional information regarding its operations and experience managing other investment accounts. Based on the foregoing information, the Board, including the Independent Directors, concluded that the Sub-Adviser had provided quality services and would continue to do so for the Fund.
