MANAGEMENT DISCUSSION

Company Overview

Kayne Anderson MLP Investment Company is a non-diversified, closed-end fund that commenced operations in September 2004. Our investment objective is to obtain a high after-tax total return by investing at least 85% of our total assets in energy-related master limited partnerships and their affiliates (“MLPs”) and in other companies that operate assets used in the gathering, transporting, processing, storing, refining, distributing, mining or marketing of natural gas, natural gas liquids, crude oil, refined petroleum products or coal (collectively with MLPs, “Midstream Energy Companies”).

As of February 28, 2017, we had total assets of $4.3 billion, net assets applicable to our common stockholders of $2.4 billion (net asset value of $20.77 per share), and 114.0 million shares of common stock outstanding.

Our investments are principally in equity securities issued by MLPs, but we also may invest in debt securities of MLPs and equity/debt securities of other Midstream Energy Companies. As of February 28, 2017, we held $4.2 billion in equity investments and no debt investments.

(2) On February 1, 2017, ONEOK, Inc. (“OKE”) and ONEOK Partners, L.P. (“OKS”) announced an agreement under which OKE will acquire all common units of OKS in a stock-for-unit transaction. As of February 28, 2017, the Company did not own any OKE shares.

Results of Operations — For the Three Months Ended February 28, 2017

Investment Income.    Investment income totaled $9.2 million for the quarter. We received $75.3 million of dividends and distributions, of which $63.8 million was treated as return of capital and $2.3 million was treated as distributions in excess of cost basis. We also received $1.3 million of paid-in-kind dividends during the quarter, which are not included in investment income, but are reflected as an unrealized gain.

Operating Expenses.    Operating expenses totaled $25.2 million, including $13.7 million of investment management fees, $7.6 million of interest expense, $3.1 million of preferred stock distributions and $0.8 million of other operating expenses. Interest expense includes $0.4 million of non-cash amortization of debt issuance costs. Preferred stock distributions include $0.2 million of non-cash amortization.

Net Investment Loss.    Our net investment loss totaled $11.2 million and included a current tax expense of $0.1 million and a deferred tax benefit of $4.9 million.

Net Realized Gains.    We had net realized gains from our investments of $28.9 million, consisting of realized gains from long term investments of $45.6 million, a current tax benefit of $0.4 million and a deferred tax expense of $17.1 million.

Net Change in Unrealized Gains.    We had a net increase in our unrealized gains of $225.7 million. The net change consisted of a $356.3 million increase in our unrealized gains on investments, $0.2 million of unrealized gains from option activity and a deferred tax expense of $130.8 million.

Net Increase in Net Assets Resulting from Operations.    We had an increase in net assets resulting from operations of $243.4 million. This increase was comprised of a net investment loss of $11.2 million, net realized gains of $28.9 million and a net increase in unrealized gains of $225.7 million, as noted above.

Distributions to Common Stockholders

We pay quarterly distributions to our common stockholders, funded generally by net distributable income (“NDI”) generated from our portfolio investments. NDI is the amount of income received by us from our portfolio investments less operating expenses, subject to certain adjustments as described below. NDI is not a financial measure under the accounting principles generally accepted in the United States of America (“GAAP”). Refer to the “Reconciliation of NDI to GAAP” section below for a reconciliation of this measure to our results reported under GAAP.

Income from portfolio investments includes (a) cash dividends and distributions, (b) paid-in-kind dividends received (i.e., stock dividends), (c) interest income from debt securities and commitment fees from private investments in public equity (“PIPE investments”) and (d) net premiums received from the sale of covered calls.

Operating expenses include (a) investment management fees paid to our investment adviser (KAFA), (b) other expenses (mostly comprised of fees paid to other service providers), (c) interest expense and preferred stock distributions and (d) current and deferred income tax expense/benefit on net investment income/loss.

Net Distributable Income (NDI)

(amounts in millions, except for per share amounts)

	Three Months Ended February 28, 2017
Distributions and Other Income from Investments
Dividends and Distributions(1)	$	75.3
Paid-In-Kind Dividends(1)		1.3
Total Distributions and Other Income from Investments		76.6
Expenses
Net Investment Management Fee		(13.7	)
Other Expenses		(0.8	)
Interest Expense		(7.4	)
Preferred Stock Distributions		(2.9	)
Income Tax Benefit, net		4.8
Net Distributable Income (NDI)	$	56.6
Weighted Shares Outstanding		113.9
NDI per Weighted Share Outstanding	$	0.497
Adjusted NDI per Weighted Share Outstanding(2)	$	0.513
Distributions paid per Common Share(3)	$	0.450

(1) See Note 2 (Investment Income) to the Financial Statements for additional information regarding paid-in-kind and non-cash dividends and distributions.

(2) Adjusted NDI includes $1.9 million of consideration received in the merger of MarkWest Energy Partners, L.P. and MPLX LP. Because the acquiring entity has deemed part of the merger consideration to be compensation to help offset the lower quarterly distribution that unitholders of the acquired entity would receive after closing, we believe it to be appropriate to include this amount in Adjusted NDI. This merger consideration is not included in investment income for GAAP purposes, but rather is treated as additional consideration when calculating the realized or unrealized gain (loss) that results from the merger transaction.

(3) The distribution of $0.45 per share for the first quarter of fiscal 2017 was paid on April 21, 2017.

Last quarter, we guided to a reduction in our distribution as a result of the trend of MLPs (or GPs) with lower yields acquiring MLPs with a higher yield and this trend’s impact on our NDI. Since the time we provided this guidance, two additional transactions were announced: Williams Partners L.P. reduced its distribution in connection with its acquisition of the general partner and incentive distribution rights from its parent and the acquisition of ONEOK Partners, L.P. by its parent, ONEOK, Inc. Both transactions will have the effect of reducing our NDI. While the Williams and ONEOK transactions were viewed favorably by the market, in light of the negative impact of these transactions on NDI, we decreased our distribution by an amount greater than we had guided to last quarter. The current distribution level of $0.45 per share reflects all transactions related to our portfolio that have been announced or are currently anticipated.

Payment of future distributions is subject to Board of Directors approval, as well as meeting the covenants of our debt agreements and terms of our preferred stock. Because our quarterly distributions are funded primarily by NDI generated from our portfolio investments, the Board of Directors, in determining our quarterly distribution to common stockholders, gives a significant amount of consideration to the NDI and Adjusted NDI generated in the current quarter, as well as the NDI that our portfolio is expected to generate over the next twelve months. The Board of Directors also considers other factors, including but not limited to, realized and unrealized gains generated by the portfolio.

MANAGEMENT DISCUSSION

Reconciliation of NDI to GAAP

The difference between distributions and other income from investments in the NDI calculation and total investment income as reported in our Statement of Operations is reconciled as follows:

• GAAP recognizes that a significant portion of the cash distributions received from MLPs is characterized as a return of capital and therefore excluded from investment income, whereas the NDI calculation includes the return of capital portion of such distributions.

• GAAP recognizes distributions received from MLPs that exceed the cost basis of our securities to be realized gains and are therefore excluded from investment income, whereas the NDI calculation includes these distributions.

• NDI includes the value of paid-in-kind dividends and distributions, whereas such amounts are not included as investment income for GAAP purposes, but rather are recorded as unrealized gains upon receipt.

• NDI includes commitment fees from PIPE investments, whereas such amounts are generally not included in investment income for GAAP purposes, but rather are recorded as a reduction to the cost of the investment.

• We may hold debt securities from time to time. Certain of our investments in debt securities may be purchased at a discount or premium to the par value of such security. When making such investments, we consider the security’s yield to maturity, which factors in the impact of such discount (or premium). Interest income reported under GAAP includes the non-cash accretion of the discount (or amortization of the premium) based on the effective interest method. When we calculate interest income for purposes of determining NDI, in order to better reflect the yield to maturity, the accretion of the discount (or amortization of the premium) is calculated on a straight-line basis to the earlier of the expected call date or the maturity of the debt security.

• We may sell covered call option contracts to generate income or to reduce our ownership of certain securities that we hold. In some cases, we are able to repurchase these call option contracts at a price less than the call premium that we received, thereby generating a profit. The premium we receive from selling call options, less (i) the premium that we pay to repurchase such call option contracts and (ii) the amount by which the market price of an underlying security is above the strike price at the time a new call option is written (if any), is included in NDI. For GAAP purposes, premiums received from call option contracts sold are not included in investment income. See Note 2 — Significant Accounting Policies for a full discussion of the GAAP treatment of option contracts.

The treatment of expenses included in NDI also differs from what is reported in the Statement of Operations as follows:

• The non-cash amortization or write-offs of capitalized debt issuance costs, premiums on newly issued debt and preferred stock offering costs related to our financings is included in interest expense and distributions on mandatory redeemable preferred stock for GAAP purposes, but is excluded from our calculation of NDI.

• NDI also includes recurring payments (or receipts) on interest rate swap contracts or the amortization of termination payments on interest rate swap contracts entered into in anticipation of an offering of unsecured notes (“Notes”) or mandatory redeemable preferred stock (“MRP Shares”). The termination payments on interest rate swap contracts are amortized over the term of the Notes or MRP Shares issued. For GAAP purposes, these amounts are included in the realized gains/losses section of the Statement of Operations.

Liquidity and Capital Resources

At February 28, 2017, we had total leverage outstanding of $1,126 million, which represented 26% of total assets. Our current policy is to utilize leverage in an amount that represents approximately 30% of our total assets. As the MLP market has recovered from the recent downturn, we have been operating with leverage levels less than our stated policy. On April 20, 2017, based on our recommendation, the Board of Directors modified our policy on target leverage levels to a range of 25%-30%, effective June 30, 2017. We believe incorporating a range of target leverage levels is more appropriate given the volatility in MLP prices experienced over the past several years. See Information Regarding Changes to Investment Policy on page 35. Total leverage was comprised of $767 million of Notes, $59 million of borrowings outstanding under our unsecured term loan (the “Term Loan”) and $300 million of MRP Shares. At February 28, 2017, we did not have any borrowings outstanding under our unsecured revolving credit facility (the “Credit Facility”), and we had $1 million of cash and cash equivalents. As of April 21, 2017, we had no borrowings outstanding under our Credit Facility, $116 million outstanding under our Term Loan, and we had $1 million of cash and cash equivalents.

Our Credit Facility has a two-year term maturing on February 28, 2018 and a total commitment amount of $150 million. The interest rate on outstanding loan balances may vary between LIBOR plus 1.60% and LIBOR plus 2.25%, depending on our asset coverage ratios. We pay a fee of 0.30% per annum on any unused amounts of the Credit Facility.

Our Term Loan has a total commitment of $150 million and matures on February 18, 2019. Borrowings under the Term Loan bear interest at a rate of LIBOR plus 1.30%. Amounts borrowed under the Term Loan may be repaid and subsequently borrowed. We pay a fee of 0.25% per annum on any unused amounts of the Term Loan.

At February 28, 2017, we had $767 million of Notes outstanding that mature between 2017 and 2025 and we had $300 million of MRP Shares outstanding that are subject to mandatory redemption between 2017 and 2022. On April 24, 2017, we redeemed all $20 million of our Series Y Notes originally scheduled to mature May 3, 2017 at par value using borrowings under our Term Loan. We expect to borrow on our Term Loan or Credit Facility to refinance the MRP Shares that mature in 2017 ($8 million).

At February 28, 2017, our asset coverage ratios under the Investment Company Act of 1940, as amended (the “1940 Act”), were 423% for debt and 310% for total leverage (debt plus preferred stock). Our target asset coverage ratio with respect to our debt is 385%. At times we may be above or below this target depending on market conditions as well as certain other factors, including our target total leverage asset coverage ratio of 290% and the basic maintenance amount as stated in our rating agency guidelines.

As of February 28, 2017, our total leverage consisted 95% of fixed rate obligations and 5% of floating rate obligations. At such date, the weighted average interest/dividend rate on our total leverage was 3.56%.

(1) Distributions on the Company’s mandatory redeemable preferred stock (“MRP Shares”) are treated as an operating expense under GAAP and are included in the calculation of net investment loss. See Note 2 —Significant Accounting Policies. Distributions in the amount of $2,899 paid to holders of MRP Shares during the three months ended February 28, 2017 are estimated to be characterized as dividends (eligible to be treated as qualified dividend income). This estimate is based solely on the Company’s operating results during the period and does not reflect the expected results during the remainder of the fiscal year. The actual characterization of the MRP Shares distributions made during the period will not be determinable until after the end of the fiscal year when the Company can determine its earnings and profits. Therefore, the characterization may differ from the preliminary estimates. Distributions in the amount of $17,811 paid to holders of MRP Shares for the fiscal year ended November 30, 2016 were characterized as distributions (return of capital). This characterization is based on the Company’s earnings and profits.

(2) The characterization of the distributions paid to common stockholders for the three months ended February 28, 2017 as either dividends (eligible to be treated as qualified dividend income) or distributions (return of capital) is based solely on the Company’s operating results during the period and does not reflect the expected results during the remainder of the fiscal year. The actual characterization of the common stock distributions made during the period will not be determinable until after the end of the fiscal year when the Company can determine its earnings and profits. Therefore, the characterization may differ from the preliminary estimates.

(3) Distributions paid to common stockholders for the fiscal year ended November 30, 2016 were characterized as distributions (return of capital). This characterization is based on the Company’s earnings and profits.

(4) On December 17, 2015, the Company’s investment advisor, KA Fund Advisors, LLC, purchased $10,035 of newly issued shares funded in part with the after-tax management fees received during the fourth quarter of fiscal 2015.

FINANCIAL HIGHLIGHTS

(amounts in 000’s, except share and per share amounts)

(1) Based on average shares of common stock outstanding.

(2) Distributions on the Company’s MRP Shares are treated as an operating expense under GAAP and are included in the calculation of net investment income (loss). See Note 2 — Significant Accounting Policies.

(3) The characterization of the distribution paid for the three months ended February 28, 2017 is based solely on the Company’s operating results during the period and does not reflect the expected results during the remainder of the fiscal year. The information presented for each of the other periods is a characterization of the total distributions paid to preferred stockholders and common stockholders as either a dividend (eligible to be treated as qualified dividend income) or a distribution (return of capital) and is based on the Company’s earnings and profits.

(4) Total investment return based on market value is calculated assuming a purchase of common stock at the market price on the first day and a sale at the current market price on the last day of the period reported. The calculation also assumes reinvestment of distributions at actual prices pursuant to the Company’s dividend reinvestment plan.

(5) Not annualized.

(6) Total investment return based on net asset value is calculated assuming a purchase of common stock at the net asset value on the first day and a sale at the net asset value on the last day of the period reported. The calculation also assumes reinvestment of distributions at actual prices pursuant to the Company’s dividend reinvestment plan.

(7) Unless otherwise noted, ratios are annualized.

(8) For the fiscal years ended November 30, 2015 and November 30, 2008, the Company reported an income tax benefit of $980,647 (30.7% of average net assets) and $339,991 (29.7% of average net assets), respectively, primarily related to unrealized losses on investments. The income tax expense is assumed to be 0% because the Company reported a net deferred income tax benefit during the year.

(9) Principal/liquidation value.

(10) Calculated pursuant to section 18(a)(1)(A) of the 1940 Act. Represents the value of total assets less all liabilities not represented by Notes (principal value) or any other senior securities representing indebtedness and MRP Shares (liquidation value) divided by the aggregate amount of Notes and any other senior securities representing indebtedness. Under the 1940 Act, the Company may not declare or make any distribution on its common stock nor can it incur additional indebtedness if, at the time of such declaration or incurrence, its asset coverage with respect to senior securities representing indebtedness would be less than 300%. For purposes of this test, the Credit Facility and the Term Loan are considered senior securities representing indebtedness.

(11) Calculated pursuant to section 18(a)(2)(A) of the 1940 Act. Represents the value of total assets less all liabilities not represented by Notes (principal value), any other senior securities representing indebtedness and MRP Shares divided by the aggregate amount of Notes, any other senior securities representing indebtedness and MRP Shares (liquidation value). Under the 1940 Act, the Company may not declare or make any distribution on its common stock nor can it issue additional preferred stock if at the time of such declaration or issuance, its asset coverage with respect to all senior securities would be less than 200%. In addition to the limitations under the 1940 Act, the Company, under the terms of its MRP Shares, would not be able to declare or pay any distributions on its common stock if such declaration would cause its asset coverage with respect to all senior securities to be less than 225%. For purposes of these tests, the Credit Facility and the Term Loan are considered senior securities representing indebtedness.

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS

(amounts in 000’s, except number of option contracts, share and per share amounts)

(UNAUDITED)

1.    Organization

Kayne Anderson MLP Investment Company (the “Company”) was organized as a Maryland corporation on June 4, 2004, and is a non-diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Company’s investment objective is to obtain a high after-tax total return by investing at least 85% of its net assets plus any borrowings (“total assets”) in energy-related master limited partnerships and their affiliates (collectively, “MLPs”), and in other companies that, as their principal business, operate assets used in the gathering, transporting, processing, storing, refining, distributing, mining or marketing of natural gas, natural gas liquids (including propane), crude oil, refined petroleum products or coal (collectively with MLPs, “Midstream Energy Companies”). The Company commenced operations on September 28, 2004. The Company’s shares of common stock are listed on the New York Stock Exchange, Inc. (“NYSE”) under the symbol “KYN.”

2.    Significant Accounting Policies

The following is a summary of the significant accounting policies that the Company uses to prepare its financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Company is an investment company and follows accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 946 — “Financial Services — Investment Companies.”

A. Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expenses during the period. Actual results could differ materially from those estimates.

B. Cash and Cash Equivalents — Cash and cash equivalents include short-term, liquid investments with an original maturity of three months or less and include money market fund accounts.

C. Calculation of Net Asset Value —  The Company determines its net asset value on a daily basis and reports its net asset value on its website. Net asset value is computed by dividing the value of the Company’s assets (including accrued interest and distributions and current and deferred income tax assets), less all of its liabilities (including accrued expenses, distributions payable, current and deferred accrued income taxes, and any borrowings) and the liquidation value of any outstanding preferred stock, by the total number of common shares outstanding.

D. Investment Valuation — Readily marketable portfolio securities listed on any exchange other than the NASDAQ Stock Market, Inc. (“NASDAQ”) are valued, except as indicated below, at the last sale price 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 most recent bid and ask prices on such day. Securities admitted to trade on the NASDAQ are valued at the NASDAQ official closing price. Portfolio securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

Equity securities traded in the over-the-counter market, but excluding securities admitted to trading on the NASDAQ, are valued at the closing bid prices. Debt securities that are considered bonds are valued by using the mean of the bid and ask prices provided by an independent pricing service or, if such prices are not available or in the judgment of KA Fund Advisors, LLC (“KAFA”) such prices are stale or do not represent fair value, by an independent broker. For debt securities that are considered bank loans, the fair market value is determined by using the mean of the bid and ask prices provided by the agent or syndicate bank or principal market maker. When price quotes for securities are not available, or such prices are stale or do not represent fair value in the judgment of KAFA, fair market value will be determined using the Company’s valuation process for securities that are privately issued or otherwise restricted as to resale.

Exchange-traded options and futures contracts are valued at the last sales price at the close of trading in the market where such contracts are principally traded or, if there was no sale on the applicable exchange on such day, at the mean between the quoted bid and ask price as of the close of such exchange.

The Company holds securities that are privately issued or otherwise restricted as to resale. For these securities, as well as any security for which (a) reliable market quotations are not available in the judgment of KAFA, or (b) the independent pricing service or independent broker does not provide prices or provides a price that in the judgment of KAFA is stale or does not represent fair value, shall each be valued in a manner that most fairly reflects fair value of the security on the valuation date. Unless otherwise determined by the Board of Directors, the following valuation process is used for such securities:

• Investment Team Valuation.    The applicable investments are valued by senior professionals of KAFA who are responsible for the portfolio investments. The investments will be valued monthly with new investments valued at the time such investment was made.

• Investment Team Valuation Documentation.    Preliminary valuation conclusions will be determined by senior management of KAFA. Such valuations and supporting documentation are submitted to the Valuation Committee (a committee of the Company’s Board of Directors) and the Board of Directors on a quarterly basis.

• Valuation Committee.    The Valuation Committee meets to consider the valuations submitted by KAFA at the end of each quarter. Between meetings of the Valuation Committee, a senior officer of KAFA is authorized to make valuation determinations. All valuation determinations of the Valuation Committee are subject to ratification by the Board of Directors at its next regular meeting.

• Valuation Firm.    Quarterly, a third-party valuation firm engaged by the Board of Directors reviews the valuation methodologies and calculations employed for these securities, unless the aggregate fair value of such security is less than 0.1% of total assets.

• Board of Directors Determination.    The Board of Directors meets quarterly to consider the valuations provided by KAFA and the Valuation Committee and ratify valuations for the applicable securities. The Board of Directors considers the report provided by the third-party valuation firm in reviewing and determining in good faith the fair value of the applicable portfolio securities.

At February 28, 2017, the Company held 5.7% of its net assets applicable to common stockholders (3.2% of total assets) in securities valued at fair value pursuant to procedures adopted by the Board of Directors. The aggregate fair value of these securities at February 28, 2017 was $135,358. See Note 3 — Fair Value and Note 7 — Restricted Securities.

E. Security Transactions — Security transactions are accounted for on the date these securities are purchased or sold (trade date). Realized gains and losses are calculated using the specific identification cost basis method for GAAP purposes. For tax purposes, the Company utilizes the average cost method to compute the adjusted tax cost basis of its MLP securities.

F. Return of Capital Estimates — Distributions received from the Company’s investments in MLPs and other securities generally are comprised of income and return of capital. The Company records investment income and return of capital based on estimates made at the time such distributions are received. The Company estimates that 91% of distributions received from its MLP investments were return of capital distributions. This estimate is adjusted to actual in the subsequent fiscal year when tax reporting information related to the Company’s MLP investments is received. Such estimates for MLPs and other investments are based on historical information available from each investment and other industry sources.

(UNAUDITED)

The return of capital portion of the distributions is a reduction to investment income that results in an equivalent reduction in the cost basis of the associated investments and increases net realized gains (losses) and net change in unrealized gains (losses). If the distributions received by the Company exceed its cost basis (i.e. its cost basis has been reduced to zero), the distributions are treated as realized gains.

The Company includes all distributions received on its Statement of Operations and reduces its investment income by (i) the estimated return of capital and (ii) the distributions in excess of cost basis, if any. For the three months ended February 28, 2017, the Company estimated $63,845 of return of capital and $2,286 of distributions that were in excess of cost basis. The distributions that were in excess of cost basis were treated as realized gains.

In accordance with GAAP, the return of capital cost basis reductions for the Company’s MLP investments are limited to the total amount of the cash distributions received from such investments. For income tax purposes, the cost basis reductions for the Company’s MLP investments typically exceed cash distributions received from such investments due to allocated losses from these investments. See Note 6 — Income Taxes.

The following table sets forth the Company’s estimated return of capital portion of the distributions received from its investments.

	For the Three Months Ended February 28, 2017
Return of capital portion of dividends and distributions received		85	%
Return of capital — attributable to net realized gains (losses)	$	606
Return of capital — attributable to net change in unrealized gains (losses)		63,239
Total return of capital	$	63,845

G. Investment Income — The Company records dividends and distributions on the ex-dividend date. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts. When investing in securities with payment in-kind interest, the Company will accrue interest income during the life of the security even though it will not be receiving cash as the interest is accrued. To the extent that interest income to be received is not expected to be realized, a reserve against income is established.

Debt securities that the Company may hold will typically be purchased at a discount or premium to the par value of the security. The non-cash accretion of a discount to par value increases interest income while the non-cash amortization of a premium to par value decreases interest income. The accretion of a discount and amortization of a premium are based on the effective interest method. The amount of these non-cash adjustments, if any, can be found in the Company’s Statement of Cash Flows. The non-cash accretion of a discount increases the cost basis of the debt security, which results in an offsetting unrealized loss. The non-cash amortization of a premium decreases the cost basis of the debt security, which results in an offsetting unrealized gain. To the extent that par value is not expected to be realized, the Company discontinues accruing the non-cash accretion of the discount to par value of the debt security.

The Company may receive paid-in-kind and non-cash dividends and distributions in the form of additional units or shares from its investments. For paid-in-kind dividends, the additional units are not reflected in investment income during the period received, but are recorded as unrealized gains upon receipt. Non-cash distributions are reflected in investment income because the Company has the option to receive its distributions in cash or in additional units of the security. During the three months ended February 28, 2017, the Company received $1,256 of paid-in-kind dividends from its investment in Enbridge Energy Management, L.L.C. and $7,680 of non-cash distributions from its investments in Enterprise Products Partners L.P.

H. Distributions to Stockholders — Distributions to common stockholders are recorded on the ex-dividend date. Distributions to holders of MRP Shares are accrued on a daily basis as described in Note 12 — Preferred Stock. As required by the Distinguishing Liabilities from Equity topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (ASC 480), the Company includes the accrued distributions on its MRP Shares as an operating expense due to the fixed term of this obligation. For tax purposes the payments made to the holders of the Company’s MRP Shares are treated as dividends or distributions.

The characterization of the distributions paid to holders of MRP Shares and common stock as either a dividend (eligible to be treated as qualified dividend income) or a distribution (return of capital) is determined after the end of the fiscal year based on the Company’s actual earnings and profits and, therefore, the characterization may differ from preliminary estimates.

I. Partnership Accounting Policy — The Company records its pro-rata share of the income (loss), to the extent of distributions it has received, allocated from the underlying partnerships and adjusts the cost basis of the underlying partnerships accordingly. These amounts are included in the Company’s Statement of Operations.

J. Federal and State Income Taxation — The Company, as a corporation, is obligated to pay federal and state income tax on its taxable income. The Company invests its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Company includes its allocable share of the MLP’s taxable income or loss in computing its own taxable income. Deferred income taxes reflect (i) taxes on unrealized gains (losses), which are attributable to the difference between fair value and tax cost basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and (iii) the net tax benefit of accumulated net operating and capital losses. To the extent the Company has a deferred tax asset, consideration is given as to whether or not a valuation allowance is required. The need to establish a valuation allowance for deferred tax assets is assessed periodically by the Company based on the Income Tax Topic of the FASB Accounting Standards Codification (ASC 740), that it is more likely than not that some portion or all of the deferred tax asset will not be realized. In the assessment for a valuation allowance, consideration is given to all positive and negative evidence related to the realization of the deferred tax asset. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability (which are highly dependent on future cash distributions from the Company’s MLP holdings), the duration of statutory carryforward periods and the associated risk that operating and capital loss carryforwards may expire unused.

The Company may rely to some extent on information provided by the MLPs, which may not necessarily be timely, to estimate taxable income allocable to the MLP units held in the portfolio and to estimate the associated deferred tax liability. Such estimates are made in good faith. From time to time, as new information becomes available, the Company modifies its estimates or assumptions regarding the deferred tax liability.

The Company utilizes the average cost method to compute the adjusted tax cost basis of its MLP securities.

The Company’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. Tax years subsequent to fiscal year 2012 remain open and subject to examination by the federal and state tax authorities.

K. Derivative Financial Instruments — The Company may utilize derivative financial instruments in its operations.

In October 2016, the Securities and Exchange Commission (“SEC”) adopted new rules and forms, and amendments to certain current rules and forms, to modernize reporting and disclosure of information by registered investment companies. The amendments to Regulation S-X will require standardized, enhanced disclosure about derivatives in investment company financial statements, and will also change the rules

20

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS

(amounts in 000’s, except number of option contracts, share and per share amounts)

(UNAUDITED)

governing the form and content of such financial statements. The amendments to Regulation S-X take effect on August 1, 2017. At this time, the Company is assessing the anticipated impact of these regulatory developments and will adopt these when they become effective.

Interest rate swap contracts.    The Company may use hedging techniques such as interest rate swaps to mitigate potential interest rate risk on a portion of the Company’s leverage. Such interest rate swaps would principally be used to protect the Company against higher costs on its leverage resulting from increases in interest rates. The Company does not hedge any interest rate risk associated with portfolio holdings. Interest rate transactions the Company uses for hedging purposes expose it to certain risks that differ from the risks associated with its portfolio holdings. A decline in interest rates may result in a decline in the value of the swap contracts, which, everything else being held constant, would result in a decline in the net assets of the Company. In addition, if the counterparty to an interest rate swap defaults, the Company would not be able to use the anticipated net receipts under the interest rate swap to offset its cost of financial leverage.

Interest rate swap contracts are recorded at fair value with changes in value during the reporting period, and amounts accrued under the agreements, included as unrealized gains or losses in the Statement of Operations. Monthly cash settlements under the terms of the interest rate swap agreements or termination payments are recorded as realized gains or losses in the Statement of Operations. The Company generally values its interest rate swap contracts based on dealer quotations, if available, or by discounting the future cash flows from the stated terms of the interest rate swap agreement by using interest rates currently available in the market. See Note 8 — Derivative Financial Instruments.

Option contracts.    The Company is also exposed to financial market risks including changes in the valuations of its investment portfolio. The Company may purchase or write (sell) call options. A call option on a security is a contract that gives the holder of the option, in return for a premium, the right to buy from the writer of the option the security underlying the option at a specified exercise price at any time during the term of the option.

The Company would realize a gain on a purchased call option if, during the option period, the value of such securities exceeded the sum of the exercise price, the premium paid and transaction costs; otherwise the Company would realize either no gain or a loss on the purchased call option. The Company may also purchase put option contracts. If a purchased put option is exercised, the premium paid increases the cost basis of the securities sold by the Company.

The Company may also write (sell) call options with the purpose of generating realized gains or reducing its ownership of certain securities. If the Company writes a call option on a security, the Company has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price. The Company will only write call options on securities that the Company holds in its portfolio (i.e., covered calls).

When the Company writes a call option, an amount equal to the premium received by the Company is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Company on the expiration date as realized gains from investments. If the Company repurchases a written call option prior to its exercise, the difference between the premium received and the amount paid to repurchase the option is treated as a realized gain or loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Company has realized a gain or loss. The Company, as the writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. See Note 8 — Derivative Financial Instruments.

L.  Indemnifications — Under the Company’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Company. In addition, in the normal course of business, the Company enters into contracts that provide general indemnification to other parties. The Company’s maximum exposure under these arrangements is unknown, as this would involve future

(UNAUDITED)

claims that may be made against the Company that have not yet occurred, and may not occur. However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

M.  Offering and Debt Issuance Costs — Offering costs incurred by the Company related to the issuance of its common stock reduce additional paid-in capital when the stock is issued. Costs incurred by the Company related to the issuance of its debt (credit facility, term loan or notes) or its preferred stock are capitalized and amortized over the period the debt or preferred stock is outstanding.

In April 2015, the FASB issued Accounting Standards Update (“ASU”) No. 2015-03 “Interest — Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs”. ASU No. 2015-03 requires that all costs incurred to issue debt be presented in the balance sheet as a direct deduction from the carrying value of the debt. In August 2015, the FASB issued ASU No. 2015-15 “Interest — Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements”. ASU No. 2015-15 states that the SEC staff will not object to an entity presenting the cost of securing a revolving line of credit as an asset, regardless of whether a balance is outstanding. In the first quarter of fiscal 2017, the Company adopted ASU No. 2015-03 and ASU No. 2015-15 and has classified the costs incurred to issue Notes and MRP Shares as a deduction from the carrying value of Notes and MRP Shares on the Statement of Assets and Liabilities. Previously, these issuance costs were capitalized as an asset on the Statement of Assets and Liabilities. Additionally, the Company has updated its disclosure in Notes 11 and 12 related to the unamortized Note and MRP Share issuance costs. For the purpose of calculating the Company’s asset coverage ratios pursuant to the 1940 Act, deferred issuance costs are not deducted from the carrying value of Notes and MRP Shares. There was no financial reporting impact to information presented for prior periods as a result of this accounting standard update.

3.    Fair Value

The Fair Value Measurement Topic of the FASB Accounting Standards Codification (“ASC 820”) defines fair value as the price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants under current market conditions at the measurement date. As required by ASC 820, the Company has performed an analysis of all assets and liabilities (other than deferred taxes) measured at fair value to determine the significance and character of all inputs to their fair value determination. Inputs are the assumptions, along with considerations of risk, that a market participant would use to value an asset or a liability. In general, observable inputs are based on market data that is readily available, regularly distributed and verifiable that the Company obtains from independent, third-party sources. Unobservable inputs are developed by the Company based on its own assumptions of how market participants would value an asset or a liability.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into the following three broad categories.

• Level 1 — Valuations based on quoted unadjusted prices for identical instruments in active markets traded on a national exchange to which the Company has access at the date of measurement.

• Level 2 — Valuations based on quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or instances where prices vary substantially over time or among brokered market makers.

• Level 3 — Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect the Company’s own assumptions that market participants would use to price the asset or liability based on the best available information.

The following table presents the Company’s assets measured at fair value on a recurring basis at February 28, 2017, and the Company presents these assets by security type and description on its Schedule of Investments. Note that the valuation levels below are not necessarily an indication of the risk or liquidity associated with the underlying investment.

(1) The Company’s investment in Plains AAP, L.P. (“PAGP-AAP”) is exchangeable on a one-for-one basis into either Plains GP Holdings, L.P. (“PAGP”) shares or Plains All American Pipeline, L.P. (“PAA”) units at the Company’s option. The Company values its PAGP-AAP investment on an “as exchanged” basis based on the higher public market value of either PAGP or PAA. As of February 28, 2017, the Company’s PAGP-AAP investment is valued at PAGP’s closing price. The Company categorizes its investment as a Level 2 security for fair value reporting purposes.

The Company did not have any liabilities that were measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at February 28, 2017. For the three months ended February 28, 2017, there were no transfers between Level 1 and Level 2.

As of February 28, 2017, the Company had Notes outstanding with aggregate principal amount of $767,000 and 12,000,000 shares of MRP Shares outstanding with a total liquidation value of $300,000. See Note 11 — Notes and Note 12 — Preferred Stock.

Of the $300,000 of MRP Shares, Series F ($125,000 liquidation value) is publicly traded on the NYSE. As a result, the Company categorizes this series of MRP Shares as Level 1. The remaining series of MRP Shares and all of the Notes were issued in private placements to institutional investors and are not listed on any exchange or automated quotation system. As such, the Company categorizes all of the Notes ($767,000 aggregate principal amount) and the remaining MRP Shares ($175,000 aggregate liquidation value) as Level 3 and determines the fair value of these instruments based on estimated market yields and credit spreads for comparable instruments with similar maturity, terms and structure.

The Company records these Notes and MRP Shares on its Statement of Assets and Liabilities at principal amount or liquidation value. As of February 28, 2017, the estimated fair values of these leverage instruments are as follows.

Instrument	Principal Amount/ Liquidation  Value		Fair Value
Notes (Series W, Y through GG and II through OO)	$	767,000	$	782,400
MRP Shares (Series B, C, H, I and J)	$	175,000	$	176,200
MRP Shares (Series F)	$	125,000	$	126,550

(UNAUDITED)

The purchases of $13,868 relates to the Company’s investments in Dominion Midstream Partners, LP convertible preferred units (December 2016).

The $16,224 transfers out to Level 1 relate to the Company’s investments in Rice Midstream Partners LP that became marketable during the first quarter of 2017 and Western Gas Partners, LP convertible preferred units which were partially converted into common units during the first quarter of 2017. The Company utilizes the beginning of the reporting period method for determining transfer between levels.

The $11,393 of net unrealized gains relates to investments that are still held at the end of the reporting period, and the Company includes these unrealized gains on the Statement of Operations — Net Change in Unrealized Gains (Losses).

Valuation Techniques and Unobservable Inputs

Unless otherwise determined by the Board of Directors, the Company values its private investments in public equity (“PIPE”) investments that are convertible into or otherwise will become publicly tradeable (e.g., through subsequent registration or expiration of a restriction on trading) based on the market value of the publicly-traded security less a discount. This discount is initially equal to the discount negotiated at the time the Company agrees to a purchase price. To the extent that such securities are convertible or otherwise become publicly traded within a time frame that may be reasonably determined, this discount will be amortized on a straight line basis over such estimated time frame.

The Company owns convertible preferred units of Western Gas Partners, LP (“WES”). During the first quarter of 2017, the Company entered into an early conversion agreement with WES (the “WES Conversion Agreement”) whereby the terms of the original purchase agreement were modified to allow the early conversion of the WES convertible preferred units into common units on a one-for-one basis. Under the terms of the WES Conversion Agreement, fifty percent of the WES convertible preferred units were converted into common units during the first quarter of 2017. The remaining fifty percent of the WES convertible preferred units will convert into common units during the second quarter of 2017. For the WES convertible preferred units that have not yet converted, the Company’s Board of Directors has determined that it is appropriate to value these units based on the market value of the publicly-traded WES units less a discount to account for the expected period of illiquidity until the conversion occurs.

The Company owns convertible preferred units of Capital Product Partners L.P. (“CPLP”), Dominion Midstream Partners, LP (“DM”) and MPLX LP (“MPLX”) that were issued in private placements. The convertible preferred units are (in the case of CPLP), or will be (in the case of DM and MPLX), convertible on a one-for-one basis into common units and are senior to the underlying common units of CPLP, DM and MPLX in terms of liquidation preference and priority of distributions. The Company’s Board of Directors has determined that it is appropriate to value the convertible preferred units using a convertible pricing model. This model takes into account the attributes of the convertible preferred units, including the preferred dividend, conversion ratio and call features, to determine the estimated value of such units. In using this model, the Company estimates (i) the credit spread for the convertible preferred units, which is based on credit spreads for comparable companies for CPLP and DM and the credit spread of the partnership’s unsecured notes in the case of MPLX, and (ii) the expected volatility for the underlying common units, which is based on historical volatility. For CPLP, the Company applies a discount to the value derived from the convertible pricing model to account for an expected discount in market prices for convertible securities relative to the values calculated using the pricing model. For DM and MPLX, the Company applies a discount to the value derived from the convertible pricing model to account for the expected period of illiquidity. In each case, if the resulting price for the convertible preferred units is less than the public market price for the underlying common units at such time, the public market price for the common units will be used to value the convertible preferred units.

The Company also has a private investment in the Creditors Trust of Miller Bros. Coal, LLC (“Clearwater Trust”), which is a privately held entity. Clearwater Trust has an overriding royalty interest in certain coal reserves that were sold as part of the reorganization of Clearwater Natural Resources, LP. Clearwater Trust has agreed to sell this overriding royalty interest and is receiving monthly installment payments through September 2017 from the buyer as payment for this royalty interest. The Company values its interest in Clearwater Trust based on the discounted cash flow from the expected monthly installment payments. Generally an increase in the discount rate selected by the Company will result in a decrease in the fair value of Clearwater Trust.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period. Additionally, the fair value of the Company’s investments may differ from the values that would have been used had a ready market existed for such investments and may differ materially from the values that the Company may ultimately realize.

The following table summarizes the significant unobservable inputs that the Company used to value its portfolio investments categorized as Level 3 as of February 28, 2017:

4.    Concentration of Risk

The Company’s investments are concentrated in the energy sector. The focus of the Company’s portfolio within the energy sector may present more risks than if the Company’s portfolio were broadly diversified across numerous sectors of the economy. A downturn in the energy sector would have a larger impact on the Company than on an investment company that does not focus on the energy sector. The performance of securities in the energy sector may lag the performance of other industries or the broader market as a whole. Additionally, to the extent that the Company invests a relatively high percentage of its assets in the securities of a limited number of issuers, the Company may be more susceptible than a more widely diversified investment company to any single economic, political or regulatory occurrence. At February 28, 2017, the Company had the following investment concentrations:

Category	Percent of Long-Term Investments
Securities of energy companies		100.0	%
Equity securities		100.0	%
Securities of MLPs(1)		95.8	%
Midstream Energy Companies		100.0	%
Largest single issuer		12.6	%
Restricted securities		4.2	%

(1) Securities of MLPs consist of energy-related partnerships and their affiliates (including affiliates of MLPs that own general partner interests or, in some cases subordinated units, registered or unregistered common

5.    Agreements and Affiliations

A. Administration Agreement — The Company has entered into an administration and accounting agreement with Ultimus Fund Solutions, LLC (“Ultimus”), which may be amended from time to time. Pursuant to the agreement, Ultimus will provide certain administrative and accounting services for the Company. The agreement has automatic one-year renewals unless earlier terminated by either party as provided under the terms of the agreement.

B. Investment Management Agreement — The Company has entered into an investment management agreement with KA Fund Advisors, LLC (“KAFA”) under which KAFA, subject to the overall supervision of the Company’s Board of Directors, manages the day-to-day operations of, and provides investment advisory services to, the Company. For providing these services, KAFA receives an investment management fee from the Company. KAFA has also entered into a fee waiver agreement with the Company that provides for a management fee of 1.375% on average total assets up to $4,500,000, a fee of 1.25% on average total assets between $4,500,000 and $9,500,000, a fee of 1.125% on average total assets between $9,500,000 and $14,500,000 and a fee of 1.0% on average total assets in excess of $14,500,000. On March 30, 2017, the Company renewed its investment management agreement and fee waiver agreement with KAFA for a period of one year. The investment management and fee waiver agreements will expire on March 31, 2018 and may be renewed annually thereafter upon approval of the Company’s Board of Directors (including a majority of the Company’s directors who are not “interested persons” of the Company, as such term is defined in the 1940 Act). For the three months ended February 28, 2017, the Company paid management fees at an annual rate of 1.375% of the Company’s average quarterly total assets (as defined in the investment management agreement).

For purposes of calculating the management fee the average total assets for each quarterly period are determined by averaging the total assets at the last day of that quarter with the total assets at the last day of the prior quarter. The Company’s total assets are equal to the Company’s gross asset value (which includes assets attributable to the Company’s use of preferred stock, commercial paper or notes and other borrowings and excludes any net deferred tax asset), minus the sum of the Company’s accrued and unpaid dividends and distributions on any outstanding common stock and accrued and unpaid dividends and distributions on any outstanding preferred stock and accrued liabilities (other than liabilities associated with borrowing or leverage by the Company and any accrued taxes, including, a deferred tax liability). Liabilities associated with borrowing or leverage by the Company include the principal amount of any borrowings, commercial paper or notes issued by the Company, the liquidation preference of any outstanding preferred stock, and other liabilities from other forms of borrowing or leverage such as short positions and put or call options held or written by the Company.

C. Portfolio Companies — From time to time, the Company may “control” or may be an “affiliate” of one or more of its portfolio companies, as each of these terms is defined in the 1940 Act. In general, under the 1940 Act, the Company would be presumed to “control” a portfolio company if the Company and its affiliates owned 25% or more of its outstanding voting securities and would be an “affiliate” of a portfolio company if the Company and its affiliates owned 5% or more of its outstanding voting securities. The 1940 Act contains prohibitions and restrictions relating to transactions between investment companies and their affiliates (including the Company’s investment adviser), principal underwriters and affiliates of those affiliates or underwriters.

The Company believes that there are several factors that determine whether or not a security should be considered a “voting security” in complex structures such as limited partnerships of the kind in which the Company invests. The Company also notes that the Securities and Exchange Commission (the “SEC”) staff has issued guidance on the circumstances under which it would consider a limited partnership interest to constitute a voting security. Under most partnership agreements, the management of the partnership is vested in the general

26

NOTES TO FINANCIAL STATEMENTS

(UNAUDITED)

partner, and the limited partners, individually or collectively, have no rights to manage or influence management of the partnership through such activities as participating in the selection of the managers or the board of the limited partnership or the general partner. As a result, the Company believes that many of the limited partnership interests in which it invests should not be considered voting securities. However, it is possible that the SEC staff may consider the limited partner interests the Company holds in certain limited partnerships to be voting securities. If such a determination were made, the Company may be regarded as a person affiliated with and controlling the issuer(s) of those securities for purposes of Section 17 of the 1940 Act.

In making such a determination as to whether to treat any class of limited partnership interests the Company holds as a voting security, the Company considers, among other factors, whether or not the holders of such limited partnership interests have the right to elect the board of directors of the limited partnership or the general partner. If the holders of such limited partnership interests do not have the right to elect the board of directors, the Company generally has not treated such security as a voting security. In other circumstances, based on the facts and circumstances of those partnership agreements, including the right to elect the directors of the general partner, the Company has treated those securities as voting securities. If the Company does not consider the security to be a voting security, it will not consider such partnership to be an “affiliate” unless the Company and its affiliates own more than 25% of the outstanding securities of such partnership. Additionally, certain partnership agreements give common unitholders the right to elect the partnership’s board of directors, but limit the amount of voting securities any limited partner can hold to no more than 4.9% of the partnership’s outstanding voting securities (i.e., any amounts held in excess of such limit by a limited partner do not have voting rights). In such instances, the Company does not consider itself to be an affiliate if it owns more than 5% of such partnership’s common units.

There is no assurance that the SEC staff will not consider that other limited partnership securities that the Company owns and does not treat as voting securities are, in fact, voting securities for the purposes of Section 17 of the 1940 Act. If such determination were made, the Company will be required to abide by the restrictions on “control” or “affiliate” transactions as proscribed in the 1940 Act. The Company or any portfolio company that it controls, and its affiliates, may from time to time engage in certain of such joint transactions, purchases, sales and loans in reliance upon and in compliance with the conditions of certain exemptive rules promulgated by the SEC. The Company cannot make assurances, however, that it would be able to satisfy the conditions of these rules with respect to any particular eligible transaction, or even if the Company were allowed to engage in such a transaction, that the terms would be more or as favorable to the Company or any company that it controls as those that could be obtained in an arm’s length transaction. As a result of these prohibitions, restrictions may be imposed on the size of positions that may be taken for the Company or on the type of investments that it could make.

Clearwater Trust — At February 28, 2017, the Company held approximately 63% of the Clearwater Trust. The Company believes that it is an “affiliate” of the trust under the 1940 Act by virtue of its majority interest in the trust.

Plains GP Holdings, L.P., Plains AAP, L.P. and Plains All American Pipeline, L.P. — Robert V. Sinnott is Co-Chairman of Kayne Anderson Capital Advisors, L.P. (“KACALP”), the managing member of KAFA. Mr. Sinnott also serves as a director of PAA GP Holdings LLC, which is the general partner of Plains GP Holdings L.P. (“PAGP”). Members of senior management of KACALP and KAFA and various affiliated funds managed by KACALP own PAGP shares, Plains All American Pipeline, L.P. (“PAA”) units and interests in Plains AAP, L.P. (“PAGP-AAP”). The Company believes that it is an affiliate of PAA, PAGP and PAGP-AAP under the 1940 Act by virtue of (i) the Company’s and other affiliated Kayne Anderson funds’ ownership interest in PAA, PAGP and PAGP-AAP and (ii) Mr. Sinnott’s participation on the board of PAA GP Holdings LLC.

ONEOK, Inc. and ONEOK Partners, L.P. — Kevin S. McCarthy, the Chief Executive Officer of the Company, serves as a director of ONEOK, Inc. (“OKE”). OKE is the general partner of ONEOK Partners, L.P. (“OKS”). Despite Mr. McCarthy’s participation on the board of OKE, the Company does not believe it is an affiliate of OKE or OKS because the Company’s and other Kayne Anderson funds’ aggregate ownership of each entity does not meet the criteria described above.

6.    Income Taxes

The Company’s taxes include current and deferred income taxes. Current income taxes reflect the estimated income tax liability or asset of the Company as of a measurement date. Deferred income taxes reflect (i) taxes on net unrealized gains (losses), which are attributable to the difference between fair market value and tax cost basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and (iii) the net tax benefit of accumulated net operating losses and capital losses, if any.

At February 28, 2017, the components of the Company’s current and deferred tax assets and liabilities are as follows.

Income tax receivable	$	7,891
Deferred tax assets:
Net operating loss carryforwards — Federal	$	111,941
Net operating loss carryforwards — State		8,394
Capital loss carryforwards — State		1,396
AMT credit carryforwards		3,631
Deferred tax liabilities:
Net unrealized gains on investment securities		(863,134	)
Total deferred income tax liability, net	$	(737,772	)

During the first quarter of fiscal 2017, the Company received refunds of $10,790 related to federal carryback claims filed during the fourth quarter of fiscal 2016 and received $37 of state refunds. The income tax receivable of $7,891 includes (i) $7,740 of federal carryback claims that are expected to be filed shortly after filing the fiscal 2016 tax returns in August 2017 and (ii) state estimated overpayment amounts of $151. The Company is also exploring the ability to carry back claims to various states.

At February 28, 2017, the Company had a federal net operating loss carryforward of $328,551 (deferred tax asset of $111,941). Realization of the deferred tax assets and net operating loss carryforwards are dependent, in part, on generating sufficient taxable income prior to expiration of the loss carryforwards. The federal net operating loss carryforward begins to expire in 2030. In addition, the Company has state net operating loss carryforwards of $309,988 (deferred tax asset of $8,394). The majority of the state net operating loss carryforwards expires during 2035.

At February 28, 2017, the Company had a state capital loss carryforward of $52,848 (deferred tax asset of $1,396). Realization of the capital loss carryforward is dependent on generating sufficient capital gains prior to the expiration of the capital loss carryforward in 2021.

(UNAUDITED)

At February 28, 2017, the Company had alternative minimum tax (“AMT”) credit carryforwards of $3,631. AMT credits can be used to reduce regular tax to the extent that regular tax exceeds the AMT in a future year. AMT credits do not expire.

Although the Company currently has a net deferred tax liability, it periodically reviews the recoverability of its deferred tax assets based on the weight of available evidence. When assessing the recoverability of its deferred tax assets, significant weight is given to the effects of potential future realized and unrealized gains on investments and the period over which these deferred tax assets can be realized, as the expiration dates for the federal capital and operating loss carryforwards range from five to twenty years.

Based on the Company’s assessment, it has determined that it is more likely than not that its deferred tax assets will be realized through future taxable income of the appropriate character. Accordingly, no valuation allowance has been established for the Company’s deferred tax assets. The Company will continue to assess the need for a valuation allowance in the future. Significant declines in the fair value of its portfolio of investments may change the Company’s assessment regarding the recoverability of its deferred tax assets and may result in a valuation allowance. If a valuation allowance is required to reduce any deferred tax asset in the future, it could have a material impact on the Company’s net asset value and results of operations in the period it is recorded.

Total income taxes were different from the amount computed by applying the federal statutory income tax rate of 35% to the net investment loss and realized and unrealized gains (losses) on investments before taxes as follows:

	For the Three Months Ended February 28, 2017
Computed federal income tax expense at 35%	$	(135,115	)
State income tax expense, net of federal tax		(6,595	)
Non-deductible distributions on MRP Shares, dividend received deductions and other, net		(977	)
Total income tax expense	$	(142,687	)

The Company primarily invests in equity securities issued by MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner of MLPs, the Company includes its allocable share of such MLPs’ income or loss in computing its own taxable income or loss. Additionally, for income tax purposes, the Company reduces the cost basis of its MLP investments by the cash distributions received, and increases or decreases the cost basis of its MLP investments by its allocable share of the MLP’s income or loss. During the three months ended February 28, 2017, the Company reduced its tax cost basis by $154,289 due to its fiscal 2016 net allocated losses from its MLP investments.

The Company utilizes the average cost method to compute the adjusted tax cost basis of its MLP securities.

At February 28, 2017, the cost basis of investments for federal income tax purposes was $1,925,659. The cost basis for federal income tax purposes is $904,814 lower than the cost basis for GAAP reporting purposes primarily due to the additional basis adjustments attributable to the Company’s share of the allocated losses from its MLP investments. At February 28, 2017, gross unrealized appreciation and depreciation of investments and options for federal income tax purposes were as follows:

Gross unrealized appreciation of investments (including options, if any)	$	2,360,164
Gross unrealized depreciation of investments (including options, if any)		(44,074	)
Net unrealized appreciation of investments	$	2,316,090

7.    Restricted Securities

From time to time, the Company’s ability to sell certain of its investments is subject to certain legal or contractual restrictions. For instance, private investments that are not registered under the Securities Act of 1933, as amended (the “Securities Act”), cannot be offered for public sale in a non-exempt transaction without first being registered. In other cases, certain of the Company’s investments have restrictions such as lock-up agreements that preclude the Company from offering these securities for public sale.

At February 28, 2017, the Company held the following restricted investments:

Interest Rate Swap Contracts — The Company may enter into interest rate swap contracts to partially hedge itself from increasing expense on its leverage resulting from increasing interest rates. At the time the interest rate swap contracts reach their scheduled termination, there is a risk that the Company would not be able to obtain a replacement transaction or that the terms of the replacement transaction would not be as favorable as on the expiring transaction. In addition, if the Company is required to terminate any swap contract early, then the Company could be required to make a termination payment. As of February 28, 2017, the Company did not have any interest rate swap contracts or any derivative instrument outstanding.

INFORMATION REGARDING CHANGES TO INVESTMENT POLICY

(UNAUDITED)

On April 20, 2017, the Company’s Board of Directors approved the following change to its non-fundamental investment policy related to the use of leverage:

The prior policy allowed for the Company to utilize borrowings and preferred stock (each a “Leverage Instrument” and collectively “Leverage Instruments”) in an amount that represented approximately 30% of total assets, including proceeds from such Leverage Instruments. The revised policy has established target leverage levels of approximately 25-30% of total assets, including proceeds from such Leverage Instruments.

The revised policy will be effective June 30, 2017, as follows:

“Under normal market conditions, the Company’s policy is to utilize borrowings and preferred stock (each a “Leverage Instrument” and collectively “Leverage Instruments”) in an amount that represents approximately 25%-30% of total assets (the “target leverage levels”), including proceeds from such Leverage Instruments. However, the Company reserves the right at any time, based on market conditions, (i) to reduce the target leverage levels or (ii) to use Leverage Instruments to the extent permitted by the 1940 Act.”

REPURCHASE DISCLOSURE

(UNAUDITED)

Notice is hereby given in accordance with Section 23(c) of the 1940 Act, that the Company may from time to time purchase shares of its common and preferred stock and its Notes in the open market or in privately negotiated transactions.
