RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Portfolio Update	June 30, 2018 (Unaudited)

What is the Fund’s investment strategy?

The RiverNorth/DoubleLine Strategic Opportunity Fund (“the Fund”) seeks to provide current income and overall total return.

RiverNorth Capital Management, LLC (“RiverNorth”) allocates the Fund’s Managed Assets among two principal strategies: Tactical Closed-End Fund (CEF) Income Strategy and Opportunistic Income Strategy. RiverNorth manages the Tactical Closed-End Fund Income Strategy and DoubleLine Capital LP (“DoubleLine”) manages the Opportunistic Income Strategy.

RiverNorth determines which portion of the Fund’s assets is allocated to each strategy based on market conditions. The Fund may allocate between 10% to 35% of its Managed Assets to the Tactical CEF Income Strategy and 65% to 90% of its Managed Assets to the Opportunistic Income Strategy.

The Tactical CEF Income Strategy typically invests in CEFs, business development companies (BDCs) and exchange-traded funds (ETFs). The Opportunistic Income Strategy primarily invests in agency and non-agency residential mortgage-backed securities (RMBS) and commercial mortgage-backed securities (CMBS) seeking to derive value from inefficiencies within the subsectors of the fixed income market while maintaining active risk constraints.

How did the Fund perform relative to its benchmark during the reporting period?

For the year ended June 30, 2018, the Fund returned 2.12% on a net asset value (NAV) basis and -0.65% on a market price basis. The Bloomberg Barclays U.S. Aggregate Bond Index (the “Agg”) returned -0.40% during the same period.

What contributing factors were responsible for the RiverNorth/DoubleLine Strategic Opportunity Fund’s relative performance during the period?

RiverNorth Tactical CEF Income Sleeve

The RiverNorth sleeve outperformed the benchmark index during the period. The Fund benefitted from positive NAV performance among CEFs that invest in lower credit quality securities. The sleeve’s exposure to global income CEFs detracted from performance as emerging market debt significantly underperformed the Fund’s benchmark.

DoubleLine Opportunistic Income Sleeve

For the year ended June 30, 2018, the DoubleLine sleeve outperformed the Agg return of -0.40%. Alt-A securities were the largest contributors to performance within the portfolio. Other securitized sectors including asset-backed securities (ABS) and commercial mortgage-backed securities (CMBS) were also accretive to performance due primarily to interest income. Agency MBS detracted from performance as the flattening yield curve negatively impacted valuations across the sector. Fixed rate collateralized mortgage obligations (CMOs) outperformed within the sector due to interest income.

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Portfolio Update	June 30, 2018 (Unaudited)

How was the Fund positioned at the end of June 2018?

The Fund allocation was 22% RiverNorth Tactical CEF Income, and 78% DoubleLine Opportunistic Income, based on managed assets. The biggest sector allocations are to Non-Agency MBS, Agency MBS, and High Yield. The Fund is utilizing a line of credit to leverage the portfolio approximately 25%.

Past performance is no guarantee of future results.

The Bloomberg Barclays U.S. Aggregate Bond Index is an unmanaged index of investment-grade fixed-rate debt issues with maturities of at least one year. The index cannot be invested in directly and does not reflect fees and expenses.

A credit spread is the difference in yield between two bonds of similar maturity but different credit quality. Widening credit spreads indicate growing concern about the ability of corporate (and other private) borrowers to service their debt. Narrowing credit spreads indicate improving private creditworthiness.

Yield curve is a line that plots the interest rates, at a set point in time, of bonds having equal credit quality, but differing maturity dates. The shape of the yield curve is closely scrutinized because it helps to give an idea of future interest rate change and economic activity. There are three main types of yield curve shapes: normal (steep), inverted (negative), and flat. A normal yield curve is one in which longer maturity bonds have a higher yield compared to shorter-term bonds due to the risks associated with time. An inverted yield curve is one in which the shorter-term yields are higher than the longer-term yields. A flat yield curve is one in which the shorter- and longer-term yields are very close to each other. The slope of the yield curve is also seen as important: the greater the slope, the greater the gap between short- and long-term rates.

Notes To Financial Statements	June 30, 2018

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.

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Notes To Financial Statements	June 30, 2018

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. For the period from July 2017 through September 2017, the Fund made regular monthly distributions of $0.12 per 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.

Notes To Financial Statements	June 30, 2018

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, 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.

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 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

Annual Report | June 30, 2018 23

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.
Notes To Financial Statements	June 30, 2018

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, 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

Notes To Financial Statements	June 30, 2018

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

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 year during which the credit facility was utilized from July 1, 2017 through June 30, 2018 was approximately $71,700,000 and 2.49 percent, respectively.

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.

Item 3. Audit Committee Financial Expert.

The registrant’s board of directors has determined that there is at least one audit committee financial expert serving on its audit committee. James G. Kelly is the “audit committee financial expert” and is considered to be “independent” as each term is defined in Item 3 of Form N-CSR.

Item 4. Principal Accountant Fees and Services.

The registrant has engaged its principal accountant to perform audit services, audit-related services, tax services and other services during the past fiscal year. “Audit services” refer to performing an audit of the registrant's annual financial statements or services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements for that fiscal year. “Audit-related services” refer to the assurance and related services by the principal accountant that are reasonably related to the performance of the audit. “Tax services” refer to professional services rendered by the principal accountant for tax compliance, tax advice, and tax planning. The following table details the aggregate fees billed or expected to be billed for each of the last two fiscal years for audit fees, audit-related fees, tax fees and other fees by the principal accountant.

	Year Ended 6/30/2018	Period from 9/28/2016 (inception) to 6/30/2017
Audit Fees	$26,000	$31,000
Audit-Related Fees	$ -	$ -
Tax Fees	$5,000	$5,000
All Other Fees	$ -	$ -

The Audit Committee has adopted pre-approval policies and procedures that require the audit committee to pre-approve all audit and non-audit services of the registrant, including services provided to any entity affiliated with the registrant.

The percentage of fees billed by Cohen Fund Audit Services applicable to non-audit services pursuant to waiver of pre-approval requirement were as follows:

	Year Ended 6/30/2018	Period from 9/28/2016 (inception) to 6/30/2017
Audit-Related Fees	0%	0%
Tax Fees	0%	0%
All Other Fees	0%	0%

All of the principal accountant’s hours spent on auditing the registrant’s financial statements were attributed to work performed by full-time permanent employees of the principal accountant. The following table indicates the non-audit fees billed or expected to be billed by the registrant’s accountant for services to the registrant and to the registrant’s investment adviser (and any other controlling entity, etc.—not sub-adviser) for the last year. The Audit Committee has considered whether the provision of non-audit services billed to the Adviser were compatible with maintaining the principal accountant's independence and has concluded that the provision of such non-audit services by the accountant has not compromised the accountant’s independence.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

The Board of Directors of the Fund has delegated responsibilities for decisions regarding proxy voting for securities held by the Fund to the Adviser or Subadviser. The Adviser or Subadviser will vote such proxies in accordance with its proxy policies and procedures. In some instances, the Adviser or Subadviser may be asked to cast a proxy vote that presents a conflict between the interests of the Fund’s shareholders, and those of the Adviser or Subadviser or an affiliated person of the Adviser or Subadviser. In such a case, the Adviser or Subadviser will abstain from making a voting decision and will forward all necessary proxy voting materials to the Fund to enable the Board of Directors to make a voting decision. The Adviser or Subadviser shall make a written recommendation of the voting decision to the Board of Directors, which shall include: (i) an explanation of why it has a conflict of interest; (ii) the reasons for its recommendation; and (iii) an explanation of why the recommendation is consistent with the Adviser’s (or Subadviser’s) proxy voting policies. The Board of Directors shall make the proxy voting decision that in its judgment, after reviewing the recommendation of the Adviser or Subadviser, is most consistent with the Adviser’s or Subadviser’s proxy voting policies and in the best interests of Fund shareholders. When the Board of Directors of the Fund is required to make a proxy voting decision, only the directors without a conflict of interest with regard to the security in question or the matter to be voted upon shall be permitted to participate in the decision of how the Fund’s vote will be cast. The Adviser and Subadviser vote proxies pursuant to the proxy voting policies and guidelines set forth in Appendix A and B, respectively, to this SAI.

Conflicts of Interest

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one fund or other accounts. More specifically, portfolio managers who manage multiple funds are presented with the following potential conflicts:

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. The management of multiple funds and accounts also may give rise to potential conflicts of interest if the funds and accounts have different objectives, benchmarks, time horizons and fees as the portfolio manager must allocate his time and investment ideas across multiple funds and accounts. Another potential conflict of interest may arise where another account has the same investment objective as the Fund, whereby the portfolio manager could favor one account over another.

With respect to securities transactions for the Fund, the Adviser determines which broker to use to execute each order, consistent with the duty to seek best execution of the transaction. A portfolio manager may execute transactions for another fund or account that may adversely impact the value of securities held by the Fund. Securities selected for funds or accounts other than the Fund may outperform the securities selected for the Fund. Further, a potential conflict could include a portfolio manager’s knowledge about the size, timing and possible market impact of Fund trades, whereby they could use this information to the advantage of other accounts and to the disadvantage of the Fund. These potential conflicts of interest could create the appearance that a portfolio manager is favoring one investment vehicle over another.

The management of personal accounts also may give rise to potential conflicts of interest. Although the portfolio manager generally does not trade securities in his or her own personal account, the Adviser and the Fund have each adopted a code of ethics that, among other things, permits personal trading by employees (including trading in securities that can be purchased, sold or held by the Fund) under conditions where it has been determined that such trades would not adversely impact client accounts. Nevertheless, the management of personal accounts may give rise to potential conflicts of interest, and there is no assurance that these codes of ethics will adequately address such conflicts.

The Adviser has adopted certain compliance procedures which are designed to address these types of conflicts. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.
