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 cost 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. Paydown gains and losses on mortgage-related and other asset-backed securities are recorded as components of interest income on the Statement of Operations.

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.

Semi-Annual Report | December 31, 2018 21

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Notes To Financial Statements	December 31, 2018 (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 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 (“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 managed 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 mean 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, 2018 23

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Notes To Financial Statements	December 31, 2018 (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. 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, 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) 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.

The Adviser provides a Chief Compliance Officer to the Fund. For the period from July 1, 2018 through December 31, 2018, the Fund incurred expenses of $20,700 for these services. In addition, the Fund owed the Adviser $9,200 for such expenses as of December 31, 2018.

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: 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 years ended June 30, 2017 and June 30, 2018, were as follows:

Fiscal Year Ended	Ordinary Income		Net Long Term Capital Gains		Return of Capital		Total
June 30, 2017	$	10,132,666	$	—	$	—	$	10,132,666
June 30, 2018		15,389,348		7,188		3,437,041		18,833,577

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, 2018,

26 (888) 848-7569 | www.rivernorth.com

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Notes To Financial Statements	December 31, 2018 (Unaudited)

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)
$—	$2,482,371	$(2,482,371)

At June 30, 2018, the components of distributable earnings on a tax basis for the Fund was as follows:

Undistributed Ordinary Income	Undistributed Long Term Gain/(Loss)	Net Unrealized Appreciation/ (Depreciation)	Other Accumulated Gain/(Loss)	Total
$—	$—	$(4,646,180)	$(806,025)	$(5,452,205)

Unrealized Appreciation and Depreciation on Investments: As of June 30, 2018, 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
$3,765,857	$8,412,037	$(4,646,180)	$286,013,898

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.

Capital Losses: As of June 30, 2018, the Fund had capital loss carryforwards which may reduce the Fund’s taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code and thus may reduce the amount of the distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal tax pursuant to the Internal Revenue Code. The capital loss carryforwards may be carried forward indefinitely. Capital losses carried forward for the year ended June 30, 2018, were as follows:

Non-Expiring Short-Term	Non-Expiring Long –Term
$—	$806,025

6. INVESTMENT TRANSACTIONS

Investment transactions for the period from July 1, 2018 through December 31, 2018, excluding short-term investments, were as follows:

Purchases of Securities	Proceeds from Sales of Securities
$44,810,525	$37,924,554

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.

On December 16, 2016, the Fund entered into a $75,000,000 secured, revolving, evergreen credit facility with U.S. Bank National Association (“U.S. Bank”). The Fund incurred a $75,000 administrative fee upon entering into the credit facility. The credit facility has a variable annual interest rate equal to one-month LIBOR plus 0.95 percent. The credit facility will accrue a commitment fee equal to an annual rate of 0.10 percent on $75,000,000.

The average principal balance and interest rate for the period during which the credit facility was utilized from July 1, 2018 through December 31, 2018 was approximately $73,500,000 and 3.18 percent, respectively. At December 31, 2018, the principal balance outstanding was $73,500,000 at an interest rate of 3.51 percent. For the period from July 1, 2018 through December 31, 2018, the Fund reached its maximum amount outstanding of $73,500,000 on July 1, 2018. Securities that have been pledged as collateral for the borrowings are indicated in the Schedule of Investments.

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.

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.

The Fund has issued and outstanding 11,013,787 shares for the six months ended December 31, 2018, and the year ended June 30, 2018.

10. RECENT ACCOUNTING PRONOUNCEMENTS

In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) “Premium Amortization on Purchased Callable Debt Securities”, which amends the amortization period for a callable debt security held at a premium from the maturity date to the earliest call date. The guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. At this time, management is evaluating the implications of these changes on the Fund.

In August 2018, the FASB issued ASU 2018-13, which changes the fair value measurement disclosure requirements of FASB ASC Topic 820, Fair Value Measurement. The update to Topic 820 includes new, eliminated, and modified disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods. Early adoption is permitted for any eliminated or modified disclosures. Management is currently evaluating the impact of the ASU to the financial statements.

On October 4, 2018, the Securities and Exchange Commission (“SEC”) amended Regulation S-X to require certain financial statement disclosure requirements to conform them to GAAP for investment companies. Effective November 4, 2018, the Fund adopted disclosure requirement changes for Regulation S-X, which are reflected throughout this report. The Fund’s adoption of the amendments, effective with the financial statements prepared as of December 31, 2018, had no effect on the Fund’s net assets or results of operations.

11. SUBSEQUENT EVENTS

BOARD APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT

At an in-person meeting of the Board, held on November 14, 2018 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 June 30, 2018. 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 the three months and one-year periods, and slightly below the median for its peer group for the since inception period. The Directors also noted that the Fund had outperformed its benchmark index since its inception. The Directors also reviewed the Fund’s performance relative to other funds managed by the Adviser. In consideration of each item noted, the Board agreed that the Fund’s performance was adequate.

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 1.66% was higher than the Multisector Bond fund peer group median of 1.36%. The Board noted that the highest expense ratio in the peer group was 2.14%, while the lowest was 0.76%.

The Board also noted that the annual management fee of 1.22% for the Fund was slightly above the 1.17% median paid by the peer group. 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.

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 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. 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. 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 14, 2018 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 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 adequate.

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 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.

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.
