NOTES TO CONSOLIDATED SCHEDULE OF INVESTMENTS (Unaudited)

Note 1.  Organization and Significant Accounting Policies

Cohen & Steers MLP Income and Energy Opportunity Fund, Inc. (the Fund) was incorporated under the laws of the State of Maryland on December 13, 2012 and is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a non-diversified, closed-end management investment company. The Fund applies investment company accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.  The Fund’s investment objective is to provide attractive total return, comprised of high current income and price appreciation. The Fund had no operations until February 8, 2013 when it sold 5,250 common shares to Cohen & Steers Capital Management Inc. (the investment advisor). Investment operations commenced on March 26, 2013.

Cohen & Steers MLP Investment Fund (the Subsidiary), a wholly-owned subsidiary of the Fund organized under the laws of the state of Maryland, was formed on January 30, 2013 and commenced operations on March 26, 2013. The Subsidiary acts as an investment vehicle for the Fund in order to effect certain investments on behalf of the Fund, consistent with the Fund’s investment objectives and policies as described in the Fund’s prospectus. The Fund expects that it will achieve a significant portion of its exposure to Master Limited Partnerships (MLPs) through investment in the Subsidiary. Unlike the Fund, the Subsidiary may invest without limitation in MLPs. As of August 31, 2014, the Fund held an investment of $164,166,935 in the Subsidiary, representing 20.9% of the Fund’s total assets (based on U.S. Federal income tax regulations). The Consolidated Schedule of Investments includes the accounts of the Fund and the Subsidiary. Where the context requires, the “Fund” includes both the Fund and Subsidiary. All significant inter-company balances and transactions have been eliminated in consolidation.

Note 2.  Portfolio Valuation

Investments in securities that are listed on the New York Stock Exchange (NYSE) are valued, except as indicated below, at the last sale price reflected at the close of the NYSE on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the closing bid and ask prices on such day or, if no ask price is available, at the bid price.

Securities not listed on the NYSE but listed on other domestic or foreign securities exchanges are valued in a similar manner. Securities traded on more than one securities exchange are valued at the last sale price reflected at the close of the exchange representing the principal market for such securities on the business day as of which such value is being determined. If after the close of a foreign market, but prior to the close of business on the day the securities are being valued, market conditions change significantly, certain non-U.S. equity holdings may be fair valued pursuant to procedures established by the Board of Directors.

Readily marketable securities traded in the over-the-counter market, including listed securities whose primary market is believed by the investment advisor to be over-the-counter, are valued at the last sale price on the valuation date as reported by sources deemed appropriate by the Board of Directors to reflect their fair market value. If there has been no sale on such day, the securities are valued at the mean of the closing bid and ask prices on such day or, if no ask price is available, at the bid price. However, certain fixed-income securities may be valued on the basis of prices provided by a pricing service when such prices are believed by the investment advisor, pursuant to delegation by the Board of Directors, to reflect the fair market value of such securities.

Short-term debt securities with a maturity date of 60 days or less are valued at amortized cost, which approximates fair value. Investments in open-end mutual funds are valued at their closing net asset value.

The policies and procedures approved by the Fund’s Board of Directors delegate authority to make fair value determinations to the investment advisor, subject to the oversight of the Board of Directors. The investment advisor has established a valuation committee (Valuation Committee) to administer, implement and oversee the fair valuation process according to the policies and procedures approved

annually by the Board of Directors. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.

Securities for which market prices are unavailable, or securities for which the investment advisor determines that the bid and/or ask price or a counterparty valuation does not reflect market value, will be valued at fair value, as determined in good faith by the Valuation Committee, pursuant to procedures approved by the Fund’s Board of Directors. Circumstances in which market prices may be unavailable include, but are not limited to, when trading in a security is suspended, the exchange on which the security is traded is subject to an unscheduled close or disruption or material events occur after the close of the exchange on which the security is principally traded. In these circumstances, the Fund determines fair value in a manner that fairly reflects the market value of the security on the valuation date based on consideration of any information or factors it deems appropriate. These may include, but are not limited to, recent transactions in comparable securities, information relating to the specific security and developments in the markets.

Foreign equity fair value pricing procedures utilized by the Fund may cause certain non-U.S. equity holdings to be fair valued on the basis of fair value factors provided by a pricing service to reflect any significant market movements between the time the Fund values such securities and the earlier closing of foreign markets.

The Fund’s use of fair value pricing may cause the net asset value of Fund shares to differ from the net asset value that would be calculated using market quotations. Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security may be materially different than the value that could be realized upon the sale of that security.

Fair value is defined as the price that the Fund would expect to receive upon the sale of an investment or expect to pay to transfer a liability in an orderly transaction with an independent buyer in the principal market or, in the absence of a principal market, the most advantageous market for the investment or liability. The hierarchy of inputs that are used in determining the fair value of the Fund’s investments is summarized below.

· Level 1—quoted prices in active markets for identical investments

· Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, credit risk, etc.)

· Level 3—significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

For movements between the levels within the fair value hierarchy, the Fund has adopted a policy of recognizing the transfer at the end of the period in which the underlying event causing the movement occurred. Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. There were no transfers between Level 1 and Level 2 securities as of August 31, 2014.

The following is a summary of the inputs used as of August 31, 2014 in valuing the Fund’s investments carried at value:

(a)  Certain of the Fund’s investments are categorized as Level 3 and were valued utilizing third party pricing information without adjustment. Such valuations are based on significant unobservable inputs. A change in the significant unobservable inputs could result in a significantly lower or higher value in such Level 3 investments.

(b)  Valued by a pricing service which utilized independent broker quotes.

(c)  Portfolio holdings are disclosed individually on the Consolidated Schedule of Investments.

Following is a reconciliation of investments for which significant unobservable inputs (Level 3) were used in determining fair value:

The change in unrealized appreciation (depreciation) attributable to securities owned on August 31, 2014, which were valued using significant unobservable inputs (Level 3) amounted to $172,577.

(a)  As of November 30, 2013, the Fund used significant observable inputs in determining the value of certain investments. As of August 31, 2014, the Fund used significant unobservable inputs in determining the value of the same investments.

(b)  As of November 30, 2013, the Fund used significant unobservable inputs in determining the value of this investment. As of August 31, 2014, the Fund used a quoted price in determining the value of the same investment, which resulted from the expiration of a lockup on these shares on March 3, 2014.

Note 3.  Income Tax Information

As of August 31, 2014, the federal tax cost and unrealized appreciation and depreciation in value of securities held were as follows:

Note 4.  Proposed Tax Regulation

On August 2, 2013, the Internal Revenue Service (IRS) issued proposed regulations which, if adopted in their current form, would require the Fund to limit its overall investment in MLPs to no more than 25% of the Fund’s total assets. The proposed regulations would not limit the Fund’s investments in affiliates of MLPs or other Energy Investments structured as corporations rather than as MLPs. The proposal has no immediate impact on the current operations of the Fund. It has not been determined whether, when or in what form these proposed regulations will be adopted, or, if adopted, the impact such regulations may have on the Fund. If ultimately adopted as proposed, the regulations will apply to taxable quarters beginning at least 90 days after publication of the new rules.

The IRS had requested comments on the proposed regulations by October 31, 2013, and received a number of comments. The IRS adoption of the proposed regulations remains uncertain at this time.

The Fund’s investment advisor believes that, in the event the proposed regulations are adopted in their proposed form, the Fund will be able to otherwise continue to pursue its investment objective and strategies by either (i) maintaining its status as a regulated investment company by reducing its investments in MLPs and eliminating the Subsidiary or (ii) converting to a C-Corporation for tax purposes which would allow the Fund to invest up to 100% of its assets in MLPs, but which may have a negative impact on the Fund’s net asset value on the date of conversion as a result of recognition of deferred tax expense on Fund assets not held in the Subsidiary. Any change from the Fund’s current structure may negatively affect the price at which the Fund’s shares trade, and the Fund’s investment returns and distribution yield.
