Company at a Glance

Tortoise MLP Fund, Inc. (NYSE: NTG) offers a closed-end fund strategy of investing in energy infrastructure MLPs and their affiliates, with an emphasis on natural gas infrastructure MLPs.

Investment Focus

NTG seeks to provide stockholders with a high level of total return with an emphasis on current distributions. The fund focuses primarily on “midstream” energy infrastructure MLPs that engage in the business of transporting, gathering and processing and storing natural gas and natural gas liquids (NGLs).

Under normal circumstances, we invest at least 80 percent of NTG’s total assets in MLP equity securities with at least 70 percent of total assets in natural gas infrastructure MLP equity securities. Of the total assets in the fund, we may invest as much as 50 percent in restricted securities, primarily through direct investments in securities of listed companies. We do not invest in privately held companies and limit our investment in any one security to 10 percent.

About Energy Infrastructure Master Limited Partnerships

MLPs are limited partnerships whose units trade on public exchanges such as the New York Stock Exchange (NYSE), the NYSE Alternext US and NASDAQ. Buying MLP units makes an investor a limited partner in the MLP. There are currently approximately 70 MLPs in the market, mostly in industries related to energy and natural resources.

We primarily invest in MLPs and their affiliates in the energy infrastructure sector, with an emphasis on natural gas infrastructure MLPs. Energy infrastructure MLPs are engaged in the transportation, storage and processing of crude oil, natural gas and refined products from production points to the end users. Natural gas infrastructure MLPs are companies in which over 50 percent of their revenue, cash flow or assets are related to the operation of natural gas or NGL infrastructure assets. Our investments are primarily in midstream (mostly pipeline) operations, which typically produce steady cash flows with less exposure to commodity prices than many alternative investments in the broader energy industry. With the growth potential of this sector along with our disciplined investment approach, we endeavor to generate a predictable and increasing distribution stream for our investors.

An NTG Investment Versus a Direct Investment in MLPs

We provide our stockholders an alternative to investing directly in MLPs and their affiliates. A direct MLP investment potentially offers an attractive distribution with a significant portion treated as return of capital, and a historically low correlation to returns on stocks and bonds. However, the tax characteristics of a direct MLP investment are generally undesirable for tax-exempt investors such as retirement plans. We are structured as a C Corporation — accruing federal and state income taxes based on taxable earnings and profits. Because of this innovative structure, pioneered by Tortoise Capital Advisors, institutions and retirement accounts are able to join individual stockholders as investors in MLPs.

Additional features include:

The opportunity for tax deferred distributions and distribution growth;
Simplified tax reporting (investors receive a single 1099) compared to directly owning MLP units;
Appropriate for retirement and other tax exempt accounts;
Potential diversification of overall investment portfolio; and
Professional securities selection and active management by an experienced adviser.

Dear Fellow Stockholders,

MLP company fundamentals were off to a solid start in our fiscal first quarter ended Feb. 28, 2011, despite political unrest in Egypt and Libya that continues to impact oil prices. Closer to home, the US continues to turn to natural gas, consuming between 60 to 65 billion cubic feet daily. NTG provides growth capital to MLPs investing in pipeline and storage infrastructure in North American shale regions to support the transportation of energy essential to our economy.

Master Limited Partnership Sector Review and Outlook

During our first fiscal quarter, the Tortoise MLP Total Return Index™ (TMLPT) had a total return of 9.2 percent, as an improving economy, continued MLP distribution growth and an active acquisition market propelled returns. Despite the strong sector performance, MLPs lagged the S&P 500 total return of 13.0 percent during the same period, as a result of lower relative December performance stemming in part from a rebound in the broader economic recovery.

Capital markets remained supportive of sector growth activity, with three direct placements announced during the quarter to finance acquisitions. We expect the sector to require additional growth investments as MLPs continue to focus on the tremendous build-out of midstream infrastructure in the North American oil and gas shales. In our view, this investment should translate into positive distribution growth. We anticipate MLP distribution growth between 4 and 6 percent in fiscal 2011, up slightly from our expectation for fiscal 2010 of between 3 and 5 percent.

Natural gas MLPs targeted by NTG have limited direct commodity price exposure, and many benefit from reserved capacity contracts, which result in fixed payments to the MLPs to ensure pipeline capacity availability. These “reservation charges” correspond to the customer’s maximum natural gas requirement and are paid regardless of the actual volume transported– in fact, even if no gas is transported at all. In addition, MLPs also collect a usage charge for the physical volumes transported through their pipelines.

Company Performance Review and Outlook

Our total assets increased from more than $1.5 billion on Nov. 30, 2010 to nearly $1.7 billion on Feb. 28, 2011, primarily resulting from market appreciation of our investments. Our total return based on market value (including the reinvestment of distributions) for the first fiscal quarter of 2011 was 5.8 percent, as compared to negative 2.0 percent for the prior fiscal quarter ended Nov. 30, 2010. On a net asset value (NAV) basis, our total return was 8.6 percent for the fiscal quarter, as compared to 7.9 percent for the prior fiscal quarter ended Nov. 30, 2010. We ended the fiscal quarter with a NAV approximately 6.5 percent above our initial public offering price of $25.00.

We paid a distribution of $0.4075 per common share ($1.63 annualized) to our stockholders on March 1, 2011, a 13 percent increase from our prior quarter partial distribution of $0.36. Our distribution reflected the full investment of our equity and leverage capital and slightly surpassed our guidance of not less than $0.40625 per common share. Based on our closing fiscal quarter price of $25.14, our first fiscal quarter distribution represents an annualized yield of 6.5 percent. Our payout ratio of distributions to distributable cash flow (DCF) for the fiscal quarter was 96.2 percent, which is in line with our expectations to pay at least 95 percent of DCF to stockholders annually.

NTG continued to finance energy infrastructure sector growth with the completion of two direct placement investments totaling $61 million during the fiscal quarter. Through these investments, we acquired common units in PAA Natural Gas Storage, L.P. and Buckeye Partners, L.P., which used the proceeds to help finance acquisitions in natural gas and crude oil/refined products storage assets, respectively.

We ended our fiscal quarter with leverage at 20.7 percent of total assets, well below our long-term target of 25 percent. We continue to seek to emphasize quality and DCF sustainability through a conservative leverage policy. As of fiscal quarter end, 84.7 percent of our leverage had fixed interest or distribution rates, a weighted average maturity of 6.7 years and a weighted average cost of 3.65 percent.

Additional information about our financial performance is available in the Key Financial Data and Management’s Discussion of this report.

Management’s Discussion (Unaudited)

The information contained in this section should be read in conjunction with our Financial Statements and the Notes thereto. In addition, this report contains certain forward-looking statements. These statements include the plans and objectives of management for future operations and financial objectives and can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “anticipate,” “estimate,” or “continue” or the negative thereof or other variations thereon or comparable terminology. These forward-looking statements are subject to the inherent uncertainties in predicting future results and conditions. Certain factors that could cause actual results and conditions to differ materially from those projected in these forward-looking statements are set forth in the “Risk Factors” section of our public filings with the SEC.

Introduction

We include the Management’s Discussion section in each quarterly report to provide you transparency and insight into the results of operations, including comparative information to prior periods and trends. In addition, we include a “Key Financial Data” page which provides quarterly and annual detail of our distributable cash flow (“DCF”) and other important metrics, including leverage and selected operating ratios. We hope that you find this discussion and financial data a useful supplement to the GAAP financial information included in this report. The Key Financial Data page in this quarter’s report reflects information from July 30, 2010 (commencement of operations) through fiscal year end November 30, 2010, and the 2011 1st fiscal quarter ended February 28th.

Overview

Tortoise MLP Fund, Inc.’s (“NTG”) primary investment objective is to provide a high level of total return with an emphasis on current distributions paid to stockholders. We seek to provide our stockholders with an efficient vehicle to invest in a portfolio consisting primarily of energy infrastructure master limited partnerships (“MLPs”) and their affiliates, with an emphasis on natural gas infrastructure. Energy infrastructure MLPs own and operate a network of pipeline and energy-related logistical assets that transport, store, gather and process natural gas, natural gas liquids (“NGLs”), crude oil, refined petroleum products, and other resources or distribute, market, explore, develop or produce such commodities. Natural gas infrastructure MLPs are defined as companies engaged in such activities with over 50 percent of their revenue, cash flow or assets related to natural gas or NGL infrastructure assets.

NTG is a registered non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). Tortoise Capital Advisors, L.L.C. (the “Adviser”) serves as investment adviser.

NTG completed its initial public offering and commenced operations on July 30, 2010. We issued 45,400,000 shares at $25.00 per share for net proceeds after expenses of approximately $1.081 billion. We completed investment of these proceeds in late September. We issued $320 million in senior notes and mandatorily redeemable preferred stock in October, investing these proceeds by mid-November. The portfolio holdings and weightings are consistent with our target portfolio of at least 70 percent of our assets invested in natural gas infrastructure MLPs, with a focus on the midstream sector.

Company Update

Market values of our MLP investments increased during 1st quarter 2011 from their levels at November 30, 2010, contributing to an increase of $153 million in total assets. Distribution increases from our MLP investments were in-line with our expectations while the increase in total assets during the quarter resulted in increased asset-based expenses.

We declared our 1st quarter 2011 distribution of $0.4075 on February 8, 2011. This distribution reflects full investment of our IPO and leverage proceeds and equates to a 6.52 percent yield on the IPO purchase price. Additional information on these events and results of our operations are discussed below.

Critical Accounting Policies

The financial statements are based on the selection and application of critical accounting policies, which require management to make significant estimates and assumptions. Critical accounting policies are those that are both important to the presentation of our financial condition and results of operations and require management’s most difficult, complex, or subjective judgments. Our critical accounting policies are those applicable to the valuation of investments and certain revenue recognition matters as discussed in Note 2 in the Notes to Financial Statements.

Determining Distributions to Stockholders

Our portfolio generates cash flow from which we pay distributions to stockholders. We intend to pay out substantially all of our distributable cash flow (“DCF”) to holders of common stock through quarterly distributions. Our Board of Directors reviews the distribution rate quarterly, and may adjust the quarterly distributions throughout the year. Our goal is to declare what we believe to be sustainable increases in our regular quarterly distributions with increases safely covered by earned DCF. We have targeted to pay at least 95 percent of DCF on an annualized basis.

Determining DCF

DCF is simply distributions received from investments less expenses. The total distributions received from our investments include the amount we receive as cash distributions from MLPs, paid-in-kind distributions, and dividend and interest payments. The total expenses include current or anticipated operating expenses, leverage costs and current income taxes (excluding taxes generated from realized gains), if any. We expect to retain realized capital gains, if any, net of applicable taxes. Expected tax benefits are not included in our DCF. Each are summarized for you in the table on page 2 and are discussed in more detail below.

The Key Financial Data table discloses the calculation of DCF and should be read in conjunction with this discussion. The difference between distributions received from investments in the DCF calculation and total investment income as reported in the Statement of Operations, is reconciled as follows: the Statement of Operations, in conformity with U.S. generally accepted accounting principles (“GAAP”), recognizes distribution income from MLPs and common stock on their ex-dates, whereas the DCF calculation reflects distribution income on their pay dates; GAAP recognizes that a significant portion of the cash distributions received from MLPs are characterized as a return of capital and therefore excluded from investment income, whereas the DCF calculation includes the return of capital; and distributions received from investments in the DCF calculation include the value of dividends paid-in-kind (additional stock or MLP units), whereas such amounts are not included as income for GAAP purposes, and includes distributions related to direct investments when the purchase price is reduced in lieu of receiving cash distributions. The treatment of expenses in the DCF calculation also differs from what is reported in the Statement of Operations. In addition to the total operating expenses, including expense reimbursement, as disclosed in the Statement of Operations, the DCF calculation reflects interest expense, distributions to preferred stockholders, other recurring leverage expenses, as well as current taxes paid. A reconciliation of Net Investment Loss, before Income Taxes to DCF is included below.

2011 1st Quarter Report

Management’s Discussion (Unaudited)

(Continued)

Distributions Received from Investments

Our ability to generate cash is dependent on the ability of our portfolio of investments to generate cash flow from their operations. In order to maintain and grow distributions to our stockholders, we evaluate each holding based upon its contribution to our investment income, our expectation for its growth rate, and its risk relative to other potential investments.

We concentrate on MLPs we believe can expect an increasing demand for services from economic and population growth. We seek well-managed businesses with hard assets and stable recurring revenue streams. Our focus remains primarily on investing in fee-based service providers that operate long-haul, interstate pipelines. We further diversify among issuers, geographies and energy commodities to seek a distribution payment which approximates an investment directly in energy infrastructure MLPs. In addition, most energy infrastructure companies are regulated and utilize an inflation escalator index that factors in inflation as a cost pass-through. So, over the long-term, we believe MLPs’ distributions will outpace inflation and interest rate increases, and produce positive real returns.

Total distributions received from our investments for the 1st quarter 2011 was approximately $25.7 million. This reflects a full quarter’s earnings on our total capital and the receipt of a one-time commitment fee of $200,000 related to a direct MLP investment completed during the quarter. On an annualized basis, this equates to 6.49 percent of our average total assets for the quarter.

Expenses

We incur two types of expenses: (1) operating expenses, consisting primarily of the advisory fee, and (2) leverage costs. On a percentage basis, operating expenses before leverage costs were an annualized 0.78 percent of average total assets for the 1st quarter 2011. While the contractual advisory fee is 0.95 percent of average monthly managed assets, the Adviser has agreed to waive an amount equal to 0.25 percent of average monthly managed assets for year 1 and 0.10 percent of average monthly managed assets for year 2 following the closing of the initial public offering.

Leverage costs consist of two major components: (1) the direct interest expense on our senior notes and short-term credit facility, and (2) distributions to preferred stockholders. Other leverage expenses include rating agency fees and commitment fees. Total leverage costs for DCF purposes were approximately $3.3 million for the 1st quarter 2011, reflecting a full quarter of leverage expenses as we issued our leverage in October 2010.

The weighted average annual rate of our leverage at February 28, 2011 was 3.65 percent including balances on our bank credit facility which accrue interest at a variable rate equal to one-month LIBOR plus 1.25 percent. Our weighted average rate may vary in future periods as a result of changes in LIBOR, the utilization of our credit facility, and as our leverage matures or is redeemed. Additional information on our leverage is included in the Liquidity and Capital Resources discussion below.

Distributable Cash Flow

For 1st quarter 2011, our DCF was approximately $19.2 million. This equates to an annualized rate of 5.71 percent of average total assets for the quarter and 6.70 percent of average net assets for the quarter.

We declared a distribution of $18.5 million during the quarter. On a per share basis, we declared a $0.4075 distribution on February 8, 2011. This represents a full quarter of earnings and expenses and equates to a 6.52 percent yield on the $25 IPO price.

Our dividend payout ratio as a percentage of DCF was 96.2 percent for 1st quarter 2011. A payout of less than 100 percent of DCF provides cushion for on-going management of the portfolio, changes in leverage costs and other expenses. An on-going payout ratio in excess of 100 percent will, over time, erode the earning power of a portfolio and may lead to lower distributions or portfolio managers taking on more risk than they otherwise would.

Net investment loss before income taxes on the Statement of Operations is adjusted as follows to reconcile to DCF for 1st quarter 2011 (in thousands):

	1st Qtr 2011
Net Investment Loss, before Income Taxes	$	(3,752	)
Adjustments to reconcile to DCF:
Dividends paid in stock		1,042
Return of capital on distributions		21,541
Distribution included in direct placement discount		317
Amortization of debt issuance costs		94
Current income tax expenses		(12	)
DCF	$	19,230

Liquidity and Capital Resources

We had total assets of $1.678 billion at quarter-end. Our total assets reflect the value of our investments, which are itemized in the Schedule of Investments. It also reflects cash, interest and dividends receivable and any expenses that may have been prepaid. During 1st quarter 2011, total assets increased $153 million. This change was primarily the result of net realized and unrealized gains on investments of approximately $135 million during the quarter (excluding return of capital on distributions reflected during the quarter), net purchases of approximately $9 million and an increase in pending receivables for investments sold compared to the prior quarter of $9 million.

Total leverage outstanding at February 28, 2011 was $348.2 million, relatively unchanged as compared to November 30, 2010. On an adjusted basis to reflect the borrowing on our bank credit facility to fund our 1st quarter 2011 distribution, there was an increase of approximately $16 million. Outstanding leverage is comprised of approximately $230 million in senior notes, $90 million in preferred shares and $28.2 million outstanding under the credit facility, with 84.7 percent of leverage with fixed rates and a weighted average maturity of 6.7 years. Total leverage represented 20.7 percent of total assets at February 28, 2011. We’ve allowed leverage as a percent of total assets to decrease as market values increased rather than maintain leverage to total assets at the long-term target level of 25 percent of total assets. This allows the opportunity to add leverage when compelling investment opportunities arise, as was the case during the 1st quarter. Temporary increases to up to 30 percent of our total assets may be permitted, provided that such leverage is consistent with the limits set forth in the 1940 Act, and that such leverage is expected to be reduced over time in an orderly fashion to reach our long-term target. Our leverage ratio is impacted by increases or decreases in MLP values, issuance of equity and/or the sale of securities where proceeds are used to reduce leverage.

Our longer-term leverage (excluding our bank credit facility) of approximately $320 million is comprised of 72 percent private placement debt and 28 percent private placement preferred equity with a weighted average fixed rate of 3.82 percent and remaining weighted average laddered maturity of approximately 7.2 years.

We use leverage to acquire MLPs consistent with our investment philosophy. The terms of our leverage are governed by regulatory and contractual asset coverage requirements that arise from the use of leverage. Additional information on our leverage and asset coverage requirements is discussed in Note 9 and Note 10 in the Notes to Financial Statements. Our coverage ratios are updated each week on our Web site at www.tortoiseadvisors.com.

Subsequent to quarter-end, we increased the amount available under our revolving credit facility to $80 million to allow more flexibility in carrying-out our investment goals and objectives.

Management’s Discussion (Unaudited)

(Continued)

Taxation of our Distributions and Deferred Taxes

We invest in partnerships which generally have larger distributions of cash than the accounting income which they generate. Accordingly, the distributions include a return of capital component for accounting and tax purposes. Distributions declared and paid by us in a year generally differ from taxable income for that year, as such distributions may include the distribution of current year taxable income or return of capital.

The taxability of the distribution you receive depends on whether we have annual earnings and profits. If so, those earnings and profits are first allocated to the preferred shares and then to the common shares.

In the event we have earnings and profits allocated to our common shares, all or a portion of our distribution will be taxable at the 15 percent Qualified Dividend Income (“QDI”) rate, assuming various holding requirements are met by the stockholder. The portion of our distribution that is taxable may vary for either of two reasons: first, the characterization of the distributions we receive from MLPs could change annually based upon the K-1 allocations and result in less return of capital and more in the form of income. Second, we could sell an MLP investment and realize a gain or loss at any time. It is for these reasons that we inform you of the tax treatment after the close of each year as the ultimate characterization of our distributions is undeterminable until the year is over.

The portion of our distribution that is not income is treated as a return of capital. A holder of our common stock will reduce their cost basis for income tax purposes by the amount designated as return of capital. For tax purposes, the distribution to common stockholders for the fiscal year ended 2010 was 100 percent return of capital. A holder of our common stock would reduce their cost basis for income tax purposes by an amount equal to the total distributions they received in 2010. This information is reported to stockholders on Form 1099-DIV and is available on our Web site at www.tortoiseadvisors.com. For book purposes, the source of the distribution to common stockholders for the fiscal year ended 2010 was 100 percent return of capital.

The unrealized gain or loss we have in the portfolio is reflected in the Statement of Assets and Liabilities. At February 28, 2011, our investments are valued at approximately $1.665 billion, with an adjusted cost of $1.416 billion. The $249 million difference reflects unrealized appreciation that would be realized for financial statement purposes if those investments were sold at those values. The Statement of Assets and Liabilities also reflects either a net deferred tax liability or net deferred tax asset depending upon unrealized gains (losses) on investments, realized gains (losses) on investments, capital loss carryforwards and net operating losses. At February 28, 2011, the balance sheet reflects a net deferred tax liability of approximately $95 million or $2.09 per share. Accordingly, our net asset value per share represents the amount which would be available for distribution to stockholders after payment of taxes. Details of our deferred taxes are disclosed in Note 5 in our Notes to Financial Statements.

Tortoise MLP Fund, Inc.

Notes to Financial Statements (Unaudited)
February 28, 2011

1. Organization

Tortoise MLP Fund, Inc. (the “Company”) was organized as a Maryland corporation on April 23, 2010, and is a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Company’s investment objective is to seek a high level of total return with an emphasis on current distributions paid to stockholders. The Company seeks to provide its stockholders with an efficient vehicle to invest in the energy infrastructure sector, with an emphasis on natural gas infrastructure. The Company commenced operations on July 30, 2010. The Company’s stock is listed on the New York Stock Exchange under the symbol “NTG.”

2. Significant Accounting Policies

A. Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, recognition of distribution income and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

B. Investment Valuation

The Company primarily owns securities that are listed on a securities exchange or over-the-counter market. The Company values those securities at their last sale price on that exchange or over-the-counter market on the valuation date. If the security is listed on more than one exchange, the Company uses the price from the exchange that it considers to be the principal exchange on which the security is traded. Securities listed on the NASDAQ will be valued at the NASDAQ Official Closing Price, which may not necessarily represent the last sale price. If there has been no sale on such exchange or over-the-counter market on such day, the security will be valued at the mean between the last bid price and last ask price on such day.

The Company may invest up to 50 percent of its total assets in restricted securities. Restricted securities are subject to statutory or contractual restrictions on their public resale, which may make it more difficult to obtain a valuation and may limit the Company’s ability to dispose of them. Investments in restricted securities and other securities for which market quotations are not readily available will be valued in good faith by using fair value procedures approved by the Board of Directors. Such fair value procedures consider factors such as discounts to publicly traded issues, time until conversion date, securities with similar yields, quality, type of issue, coupon, duration and rating. If events occur that affect the value of the Company’s portfolio securities before the net asset value has been calculated (a “significant event”), the portfolio securities so affected will generally be priced using fair value procedures.

An equity security of a publicly traded company acquired in a direct placement transaction may be subject to restrictions on resale that can affect the security’s liquidity and fair value. Such securities that are convertible or otherwise will become freely tradable will be valued based on the market value of the freely tradable security less an applicable discount. Generally, the discount will initially be equal to the discount at which the Company purchased the securities. To the extent that such securities are convertible or otherwise become freely tradable within a time frame that may be reasonably determined, an amortization schedule may be used to determine the discount.

The Company generally values debt securities at prices based on market quotations for such securities, except those securities purchased with 60 days or less to maturity are valued on the basis of amortized cost, which approximates market value.

C. Security Transactions and Investment Income

Security transactions are accounted for on the date the securities are purchased or sold (trade date). Realized gains and losses are reported on an identified cost basis. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts. Dividend and distribution income is recorded on the ex-dividend date. Distributions received from the Company’s investments in master limited partnerships (“MLPs”) generally are comprised of ordinary income, capital gains and return of capital from the MLPs. The Company allocates distributions between investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on actual allocations received from MLPs after their tax reporting periods are concluded, as the actual character of these distributions is not known until after the fiscal year end of the Company.

For the period from December 1, 2010 through February 28, 2011, the Company estimated the allocation of investment income and return of capital for the distributions received from MLPs within the Statement of Operations. For this period, the Company has estimated approximately 11 percent as investment income and approximately 89 percent as return of capital.

D. Distributions to Stockholders

Distributions to common stockholders are recorded on the ex-dividend date. The Company may not declare or pay distributions to its common stockholders if it does not meet asset coverage ratios required under the 1940 Act of the rating agency guidelines for its debt and preferred stock following such distribution. The character of distributions to common stockholders made during the year may differ from their ultimate characterization for federal income tax purposes. For book purposes, the source of the Company’s distribution to common stockholders for the year ended November 30, 2010 and the period ended February 28, 2011 was 100 percent return of capital. For tax purposes, the Company’s distribution to common stockholders for the year ended November 30, 2010 was 100 percent return of capital. The tax character of distributions paid to common stockholders in the current year will be determined subsequent to November 30, 2011.

Distributions to mandatory redeemable preferred stockholders are accrued daily and paid quarterly based on fixed annual rates. The Company may not declare or pay distributions to its mandatory redeemable preferred stockholders if it does not meet a 200 percent asset coverage ratio for its debt or the rating agency basic maintenance amount for the debt following such distribution. The character of distributions to preferred stockholders made during the year may differ from their ultimate characterization for federal income tax purposes.

2011 1st Quarter Report 11

Notes to Financial Statements (Unaudited)
(Continued)

E. Federal Income Taxation

The Company, as a corporation, is obligated to pay federal and state income tax on its taxable income. Currently, the highest regular marginal federal income tax rate for a corporation is 35 percent. The Company may be subject to a 20 percent federal alternative minimum tax on its federal alternative minimum taxable income to the extent that its alternative minimum tax exceeds its regular federal income tax.

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 reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Company’s tax expense or benefit is included in the Statement of Operations based on the component of income or gains (losses) to which such expense or benefit relates. Deferred income taxes reflect 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. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset will not be realized.

F. Offering and Debt Issuance Costs

Offering costs related to the issuance of common stock are charged to additional paid-in capital when the stock is issued. Debt issuance costs related to long-term debt obligations and Mandatory Redeemable Preferred (“MRP”) Stock are capitalized and amortized over the period the debt and MRP Stock is outstanding.

G. Derivative Financial Instruments

The Company may use derivative financial instruments (principally interest rate swap contracts) in an attempt to manage interest rate risk. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. The Company does not hold or issue derivative financial instruments for speculative purposes. All derivative financial instruments are recorded at fair value with changes in fair value during the reporting period, and amounts accrued under the agreements, included as unrealized gains or losses in the accompanying Statement of Operations. Monthly cash settlements under the terms of the derivative instruments and the termination of such contracts are recorded as realized gains or losses in the accompanying Statement of Operations. The Company did not hold any derivative financial instruments during the period ended February 28, 2011.

H. 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 may enter into contracts that provide general indemnification to other parties. The Company’s maximum exposure under these arrangements is unknown, as this would involve future 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.

3. Concentration of Risk

Under normal circumstances, the Company intends to invest at least 80 percent of its total assets in securities of energy infrastructure companies and to invest at least 70 percent of its total assets in equity securities of natural gas infrastructure MLPs. The Company will not invest more than 10 percent of its total assets in any single issuer as of the time of purchase. The Company may invest up to 50 percent of its total assets in restricted securities. The Company will not invest in privately held companies. In determining application of these policies, the term “total assets” includes assets obtained through leverage. Companies that primarily invest in a particular sector may experience greater volatility than companies investing in a broad range of industry sectors. The Company may, for defensive purposes, temporarily invest all or a significant portion of its assets in investment grade securities, short-term debt securities and cash or cash equivalents. To the extent the Company uses this strategy, it may not achieve its investment objective.

4. Agreements

The Company has entered into an Investment Advisory Agreement with Tortoise Capital Advisors, L.L.C. (the “Adviser”). Under the terms of the agreement, the Company pays the Adviser a fee equal to an annual rate of 0.95 percent of the Company’s average monthly total assets (including any assets attributable to leverage) minus accrued liabilities (other than debt entered into for purposes of leverage and the aggregate liquidation preference of outstanding preferred stock) (“Managed Assets”), in exchange for the investment advisory services provided. The Adviser has agreed to a fee waiver of 0.25 percent of average monthly Managed Assets for the period from July 30, 2010 through July 29, 2011, and a fee waiver of 0.10 percent of average monthly Managed Assets for the period from July 30, 2011 through July 29, 2012.

U.S. Bancorp Fund Services, LLC serves as the Company’s administrator. The Company pays the administrator a monthly fee computed at an annual rate of 0.04 percent of the first $1,000,000,000 of the Company’s Managed Assets, 0.01 percent on the next $500,000,000 of Managed Assets and 0.005 percent on the balance of the Company’s Managed Assets.

(Continued)

Computershare Trust Company, N.A. serves as the Company’s transfer agent and registrar and Computershare Inc. serves as the Company’s dividend paying agent and agent for the automatic dividend reinvestment plan.

U.S. Bank, N.A. serves as the Company’s custodian. The Company pays the custodian a monthly fee computed at an annual rate of 0.004 percent of the Company’s portfolio assets, plus portfolio transaction fees.

5. Income Taxes

Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax purposes. Components of the Company’s deferred tax assets and liabilities as of February 28, 2011, are as follows:

Deferred tax assets:
Net operating loss carryforwards	$	5,045,463
Deferred tax liabilities:
Basis reduction of investment in MLPs		8,852,120
Net unrealized gains on investment securities		91,271,270
		100,123,390
Total net deferred tax liability	$	95,077,927

At February 28, 2011, a valuation allowance on deferred tax assets was not deemed necessary because the Company believes it is more likely than not that there is an ability to realize its deferred tax assets through future taxable income of the appropriate character. Any adjustments to such estimates will be made in the period such determination is made. The Company’s policy is to record interest and penalties on uncertain tax positions as part of tax expense. As of February 28, 2011, the Company had no uncertain tax positions and no penalties and interest were accrued. All tax years since inception remain open to examination by federal and state tax authorities.

Total income tax expense differs from the amount computed by applying the federal statutory income tax rate of 35 percent to net investment loss and net realized and unrealized gains on investments for the period ended February 28, 2011, as follows:

Application of statutory income tax rate	$	53,465,465
State income taxes, net of federal tax benefit		2,719,101
Nondeductible payments on preferred stock		359,368
Total income tax expense	$	56,543,934

Total income taxes are computed by applying the federal statutory rate plus a blended state income tax rate.

6. Fair Value of Financial Instruments

Various inputs are used in determining the value of the Company’s investments. These inputs are summarized in the three broad levels listed below:

	Level 1 —	quoted prices in active markets for identical investments

	Level 2 —	other significant observable inputs (including quoted prices for similar investments, market corroborated inputs, etc.)

	Level 3 —	significant unobservable inputs (including the Company’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.

The following table provides the fair value measurements of applicable Company assets by level within the fair value hierarchy as of February 28, 2011. These assets are measured on a recurring basis.

Valuation Techniques

In general, and where applicable, the Company uses readily available market quotations based upon the last updated sales price from the principal market to determine fair value. This pricing methodology applies to the Company’s Level 1 investments.

An equity security of a publicly traded company acquired in a private placement transaction without registration under the Securities Act of 1933, as amended (the “1933 Act”), is subject to restrictions on resale that can affect the security’s fair value. If such a security is convertible into publicly-traded common shares, the security generally will be valued at the common share market price adjusted by a percentage discount due to the restrictions and categorized as Level 2 in the fair value hierarchy. If the security has characteristics that are dissimilar to the class of security that trades on the open market, the security will generally be valued and categorized as Level 3 in the fair value hierarchy.

The Company utilizes the beginning of reporting period method for determining transfers between levels. There were no transfers between levels for the period from December 1, 2010 through February 28, 2011.

7. Restricted Security

Certain of the Company’s investments are restricted and are valued as determined in accordance with procedures established by the Board of Directors, as more fully described in Note 2. The table below shows the number of units held, acquisition date, acquisition cost, fair value, fair value per share and percent of net assets which the security comprises at February 28, 2011.

8. Investment Transactions

For the period from December 1, 2010 through February 28, 2011, the Company purchased (at cost) and sold securities (proceeds received) in the amount of $116,020,920 and $107,480,609 (excluding short-term debt securities), respectively.

9. Long-Term Debt Obligations

The Company has $230,000,000 aggregate principal amount of private senior notes, Series A, Series B, Series C, Series D, and Series E (collectively, the “Notes”), outstanding. The Notes are unsecured obligations of the Company and, upon liquidation, dissolution or winding up of the Company, will rank: (1) senior to all of the Company’s outstanding preferred shares; (2) senior to all of the Company’s outstanding common stock; (3) on parity with any unsecured creditors of the Company and any unsecured senior securities representing indebtedness of the Company and (4) junior to any secured creditors of the Company. Holders of the Notes are entitled to receive cash interest payments each quarter until maturity. The Series A, Series B, Series C and Series D Notes accrue interest at fixed rates and the Series E Notes accrue interest at an annual rate that resets each quarter based on the 3-month LIBOR plus 1.70 percent. The Notes are not listed on any exchange or automated quotation system.

The Notes are redeemable in certain circumstances at the option of the Company. The Notes are also subject to a mandatory redemption if the Company fails to meet asset coverage ratios required under the 1940 Act or the rating agency guidelines if such failure is not waived or cured. At February 28, 2011, the Company was in compliance with asset coverage covenants and basic maintenance covenants for its senior notes.

The estimated fair value of each series of fixed-rate Notes was calculated, for disclosure purposes, by discounting future cash flows by a rate equal to the current U.S. Treasury rate with an equivalent maturity date, plus either 1) the spread between the interest rate on recently issued debt and the U.S. Treasury rate with a similar maturity date or 2) if there has not been a recent debt issuance, the spread between the AAA corporate finance debt rate and the U.S. Treasury rate with an equivalent maturity date plus the spread between the fixed rates of the Notes and the AAA corporate finance debt rate. Estimated fair value of the Series E Notes approximates the carrying amount because the interest rate fluctuates with changes in interest rates available in the current market. The following table shows the maturity date, interest rate, notional/carrying amount and estimated fair value for each series of Notes outstanding at February 28, 2011.

		Interest			Notional/Carrying		Estimated
Series	Maturity Date	Rate			Amount		Fair Value
Series A	December 15, 2013		2.48%		$	12,000,000	$	11,982,551
Series B	December 15, 2015		3.14%			24,000,000		23,634,534
Series C	December 15, 2017		3.73%			57,000,000		55,534,460
Series D	December 15, 2020		4.29%			112,000,000		107,459,250

10. Preferred Stock

The Company has 10,000,000 shares of preferred stock authorized. Of that amount, the Company has 3,600,000 shares of private Mandatory Redeemable Preferred (“MRP”) Stock authorized and outstanding at February 28, 2011. The MRP Stock has a liquidation value of $25.00 per share plus any accumulated but unpaid distributions, whether or not declared. Holders of the MRP Stock are entitled to receive cash interest payments each quarter at a fixed rate until maturity. The MRP Stock is not listed on any exchange or automated quotation system.

The MRP Stock has rights determined by the Board of Directors. Except as otherwise indicated in the Company’s Charter or Bylaws, or as otherwise required by law, the holders of MRP Stock have voting rights equal to the holders of common stock (one vote per MRP share) and will vote together with the holders of shares of common stock as a single class except on matters affecting only the holders of preferred stock or the holders of common stock. The 1940 Act requires that the holders of any preferred stock (including MRP Stock), voting separately as a single class, have the right to elect at least two directors at all times.

The estimated fair value of each series of MRP Stock was calculated, for disclosure purposes, by discounting future cash flows by a rate equal to the current U.S. Treasury rate with an equivalent maturity date, plus either 1) the spread between the interest rate on recently issued preferred stock and the U.S. Treasury rate with a similar maturity date or 2) if there has not been a recent preferred stock issuance, the spread between the AA corporate finance debt rate and the U.S. Treasury rate with an equivalent maturity date plus the spread between the fixed rates of the MRP Stock and the AA corporate finance debt rate. The following table shows the mandatory redemption date, fixed rate, aggregate liquidation preference, number of shares outstanding and estimated fair value of each series of MRP Stock outstanding as of February 28, 2011.

			Aggregate				Estimated
	Mandatory	Fixed	Liquidation		Shares		Fair
Series	Redemption Rate	Rate	Preference		Outstanding		Value
Series A	December 15, 2015	3.69%	$	25,000,000		1,000,000	$	24,655,111
Series B	December 15, 2017	4.33%		65,000,000		2,600,000		63,452,629
			$	90,000,000		3,600,000	$	88,107,740

The MRP Stock is redeemable in certain circumstances at the option of the Company. Under the Investment Company Act of 1940, the Company may not declare dividends or make other distributions on shares of common stock or purchases of such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding MRP Stock would be less than 200 percent. The MRP Stock is also subject to a mandatory redemption if the Company fails to meet an asset coverage ratio of at least 225 percent as determined in accordance with the 1940 Act or a rating agency basic maintenance amount if such failure is not waived or cured. At February 28, 2011, the Company was in compliance with asset coverage covenants and basic maintenance covenants for its MRP Stock.

11. Credit Facility

On September 24, 2010, the Company entered into a $60,000,000 committed credit facility maturing September 23, 2011. Under the terms of the credit facility, Bank of America, N.A. serves as a lender and the lending syndicate agent on behalf of other lenders participating in the facility. The credit facility has a variable annual interest rate equal to one-month LIBOR plus 1.25 percent and unused portions of the credit facility will accrue a non-usage fee equal to an annual rate of 0.20 percent.

On January 13, 2011 the Company entered into an amendment to its credit facility. Under the terms of the amendment, the amount available under the credit facility was increased to $95,000,000 for a maximum of 120 days.

The average principal balance and interest rate for the period during which the credit facility was utilized during the period ended February 28, 2011 was approximately $47,000,000 and 1.51 percent, respectively. At February 28, 2011, the principal balance outstanding was $28,200,000 at an interest rate of 1.51 percent.

Under the terms of the credit facility, the Company must maintain asset coverage required under the 1940 Act. If the Company fails to maintain the required coverage, it may be required to repay a portion of an outstanding balance until the coverage requirement has been met. At February 28, 2011, the Company was in compliance with the terms of the credit facility.

12. Common Stock

The Company has 100,000,000 shares of capital stock authorized and 45,404,188 shares outstanding at February 28, 2011 and November 30, 2010.
