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.

For more information regarding the Fund’s investment strategies and risk see the Fund’s prospectus and statement of additional information.

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.

Semi-Annual Report | December 31, 2017

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Notes To Financial Statements	December 31, 2017 (Unaudited)

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

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.

Semi-Annual Report | December 31, 2017

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Notes To Financial Statements	December 31, 2017 (Unaudited)

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. 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 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.

5. FEDERAL INCOME TAXES

It is the Fund’s policy to meet the requirements of the Internal Revenue Code applicable to regulated investment companies, and to distribute all of their taxable net income to their 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 gain were recorded by the Fund.

The tax character of distributions paid by the Fund during the fiscal year ended June 30, 2017, was as follows:

Ordinary Income	Net Long Term Capital Gains	Return of Capital	Total
$10,132,666	$—	$—	$10,132,666

Components of Distributable Earnings on a Tax Basis: The tax components of distributable earnings are determined in accordance with income tax regulations which may differ from the composition of net assets reported under GAAP. Accordingly, for the year ended June 30, 2017, certain differences were reclassified. These differences were primarily due to book/tax distribution differences and to the different tax treatment of certain other investments; the amounts reclassified did not affect net assets. The reclassifications were as follows:

Paid-in Capital	Accumulated Net Investment Income/(Loss)	Accumulated Net Realized Gain/(Loss)
$—	$1,741,405	$(1,741,405)

Notes To Financial Statements	December 31, 2017 (Unaudited)

At June 30, 2017, the components of distributable earnings on a tax basis for the Fund was as follows:

Undistributed Ordinary Income	Undistributed Long Term Gain	Total
$1,202,858	$13,596	$1,216,454

Unrealized Appreciation and Depreciation on Investments: As of June 30, 2017, net unrealized appreciation (depreciation) of investments based on federal tax costs was as follows:

Gross Appreciation (excess of value over tax)	Gross Depreciation (excess of tax cost over value)	Net Unrealized Appreciation/ (Depreciation)	Cost of Investments for Income Tax Purposes
$6,136,669	$2,034,831	$4,101,838	$287,376,430

The difference between book and tax basis unrealized appreciation/(depreciation) for the Fund is 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, 2017, excluding short-term investments, were as follows:

8. INDEMNIFICATIONS

Under the Fund’s organizational documents, its officers and Directors are indemnified against certain liability 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 these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred.

BOARD APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT

At an in-person meeting of the Board, held on November 15, 2017 and called expressly for that purpose, the Board, including a majority of the Trustees who are not “interested persons” (as defined in the 1940 Act (the “Independent Trustees”)), considered the approval of the Management Agreement between the Adviser and the Fund. 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. 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 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 Board did not consider any single factor as controlling in determining whether or not to approve the Management Agreement.

The Board reviewed the performance of the Fund for the three months, one-year, and since inception periods ended September 30, 2017. These returns were compared to the returns of mutual funds in FUSE Research Network, LLC’s (“FUSE”) Multisector Bond fund universe. The Directors also reviewed the Fund’s performance relative to other funds managed by the Adviser. The Board concluded that the NAV performance of the Fund was slightly below the median to the Multisector Bond fund universe averages for each of the periods.

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 of 1.28% was lower than the Multisector Bond fund peer group median of 1.53%.

The Board also noted that the gross annual management fee of 1.18% for the Fund was below the 1.32% median paid by the peer group. The Board, including the Independent Directors, determined that the fees were reasonable given the nature of the services provided by the Adviser.

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 which provided details regarding the experience of each of the Adviser’s personnel. The Adviser

Semi-Annual Report | December 31, 2017

Additional Information	December 31, 2017 (Unaudited)

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.

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. In response to a question from the Directors, the Adviser noted that the Adviser’s management fees were comparable to those charged to other mutual funds to which the Adviser provides sub-advisory services. 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.

Consideration of Investment Sub-Advisory Agreement with DoubleLine Capital, LP

At an in-person meeting of the Board, held on November 15, 2017 and called expressly for that purpose, the Board, including the Independent Trustees, considered the approval of the sub-advisory agreement (the “Sub-Advisory Agreement”) between the Adviser and DoubleLine Capital, LP. 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 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 Board reviewed the performance of the portion of the Fund managed by DoubleLine relative to relevant securities indices, and to other accounts managed by DoubleLine. The Board, including the Independent Directors, concluded that the performance was in line with the universe averages and outperformed the returns of the relative benchmark index.

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.

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 Funds such investment advice as the Sub-Adviser, in

their discretion, deem 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 their 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.

As to the cost of the services to be provided and to the profits to be realized by the Sub-Adviser, the Board reviewed the Sub-Adviser’s financial condition. The Board noted that financial condition of the Sub-Adviser was stable. The Board, including the Independent Directors determined that the Sub-Advisory Agreement and the compensation to the Sub-Adviser was reasonable and the financial condition of the Sub-Adviser was adequate. The Board noted that the Sub-Adviser had 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.

TAX INFORMATION

The Fund designated 6.83% of its ordinary income distribution for the year ended June 30, 2017 as qualified dividend income and 4.60% of the dividends paid from net ordinary income qualify for the dividends received deduction available to corporate stock holders.

DIVIDEND REINVESTMENT PLAN

The Fund has a dividend reinvestment plan (the “Plan”) commonly referred to as an “opt out” plan. Each Common Shareholder who participates in the Plan will have all distributions of dividends and capital gains automatically reinvested in additional Common Shares. The automatic reinvestment of dividends and distributions in Common Shares will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends and distributions, even though such participants have not received any cash with which to pay the resulting tax. Common Shareholders who elect not to participate in the Plan will receive all distributions in cash. All correspondence or questions concerning the Plan, including how a Common Shareholder may opt out of the Plan, should be directed to U.S. Bancorp Fund Services, LLC, (855) 862-6092, 615 East Michigan Street, Milwaukee, Wisconsin 53202 (the “Plan Administrator”). 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, or opt out of, the Plan.
