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 accounting principles generally accepted in the United States of America ("GAAP"). The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures 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.

Security Valuation: The Fund's assets and other financial instruments are generally valued at their market value using market quotations. If a market 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 costs basis 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.

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 capital gains are recorded as a reduction of the cost of investments or as a realized gain, respectively.

Share Valuation: The net asset value (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 intends to elect to be treated as, and to qualify each year for special tax treatment afforded to, a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code ("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.

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 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 of Directors ("Board") approved the adoption of a managed distribution plan in accordance with Section 19(b) exemptive order whereby the Fund makes 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 manages distribution plan. The Board may amend, suspend or terminate the managed distribution plan at any time without notice to shareholders.

3. SECURITIES VALUATION AND FAIR VALUE MEASUREMENTS

Fair value is defined as the price that a 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. This includes assumptions about risk, such as 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 the 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 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.

Investments in mutual funds, including money market mutual funds, are generally priced at the ending net asset value (NAV) provided by the service agent of the funds. These securities will be categorized as Level 1 securities.

Fair values for long-term debt securities, including asset-backed obligations, non-agency collateralized mortgage obligations, and U.S. government/agency mortgage-backed securities are normally determined on the basis of the mean valuations provided by independent pricing services. Vendors typically value such securities based on one or more inputs, including but not limited to benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, spreads and other relationships observed in the markets among comparable securities, and pricing models such as yield measurers calculated using factors such as cash flows, financial or collateral performance and other reference data. In addition to these inputs, mortgage-backed and asset-backed obligations may utilize cash flows, prepayment information, default rates, delinquency and loss assumptions, collateral characteristics, credit enhancements, and specific deal information. Bank loans are normally valued on the basis of quotes obtained from brokers and dealers or independent pricing services. Securities that use similar valuation techniques and inputs are categorized as Level 2 of the fair value hierarchy. To the extent the significant inputs are unobservable, the values generally would be categorized as Level 3.

Short-term investments in fixed income securities, 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 of Directors ("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) 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 (iii) 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, 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 the Fund's NAV calculation that may affect a security's value, or the Adviser, Sub-Adviser or Valuation Committee 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 the Fund invests in default or otherwise cease to have market quotations readily available. Investments in foreign securities, junk bonds or other thinly traded securities are more likely to trigger good faith pricing than other securities.

4. RECENT ACCOUNTING PRONOUNCEMENTS

In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13"Changes to the Disclosure Requirements for Fair Value Measurement" which modifies disclosure requirements for fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. Management is currently evaluating the impact of this guidance to the Funds.

In addition, in August 2018, the Securities and Exchange Commission ("Commission") issued Final Rule Release No. 33-10532, Disclosure Update and Simplification, which in part amends certain financial statement disclosure requirements of Regulation S-X that have become redundant, duplicative, overlapping, outdated, or superseded, in light of other Commission disclosure requirements, GAAP, or changes in the information environment. The amendments are intended to facilitate the disclosure of information to investors and simplify compliance without significantly altering the total mix of information provided to investors. The amendments to Rule 6-04.17 of Regulation S-X (balance sheet) were amended to require presentation of the total, rather than the components of net assets, of distributable earnings on the balance sheet. Consistent with GAAP, funds will be required to disclose total distributable earnings. The amendments to Rule 6-09 of Regulation S-X (Statement of Changes in Net Assets) omit the requirement to separately state the sources of distributions paid as well as omit the requirement to parenthetically state the book basis amount of undistributed net investment income. Instead, consistent with GAAP, funds will be required to disclose the total amount of distributions paid, except that any tax return of capital must be separately disclosed. The requirements of the Final Rule Release are effective November 5, 2018.

Item 2. Controls and Procedures.

(a)

The Registrant's President and Treasurer have concluded that the Registrant's disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940 (the "1940 Act")) (17 CFR 270.30a-3(c)) are effective as of a date within 90 days of the filing date of the report that includes the disclosure required by this paragraph, based on the evaluation of these controls and procedures required by Rule 30a-3(b) under the 1940 Act (17 CFR 270.30a-3(b)) and Rule 13a-15(b) or Rule 15d‑15(b) under the Securities Exchange Act of 1934, as amended (17 CFR 240.13a-15(b) or 240.15d-15(d)).

(b)

There were no changes in the Registrant's internal control over financial reporting (as defined in Rule 30a-3(d) under the 1940 Act) (17 CFR 270.30a-3(d)) that occurred during the Registrant's last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Registrant's internal control over financial reporting.
