January 12, 2012

Dear Fellow Stockholders,

Our fiscal year ended Nov. 30, 2011 marked a year of memorable headlines in the broader markets. Macroeconomic events such as Eurozone debt concerns, the U.S. sovereign debt downgrade and slower than anticipated economic growth generated short-term volatility across all asset classes. Fortunately, the market recognized quality over longer periods, as evidenced by the performance of MLPs.

Master Limited Partnership Sector Review and Outlook

Notwithstanding a strong absolute return in the first half of the year, MLPs underperformed the S&P 500; however, MLPs significantly outperformed the S&P 500 during the second half of the year. Despite macro uncertainty, key business fundamentals of midstream MLPs remained steady, resulting in a solid return posted over the course of the fiscal year. The Tortoise MLP Index^® achieved a total return of 9.9 percent for the fiscal year ended Nov. 30, 2011, as compared to the S&P 500 total return of 7.8 percent for the same period.

During the year, large global energy companies continued to make significant investment in North American oil and gas shales. These deals validated the game-changing events taking place in North American energy production and transportation. Approximately $27.5 billion was invested in shale-related acquisitions in 2011 focused on the Marcellus, Eagle Ford and Fayetteville shales, as well as the Canadian oil sands. This activity drove pipeline infrastructure build-out with $12 billion in MLP pipeline projects completed in 2011. Additionally, acquisition activity remained elevated, with over $30 billion in MLP acquisitions announced this year. This year’s transactions particularly reflected natural gas pipeline MLP activity and the potential for asset migration into MLPs, with Energy Transfer Equity’s pending $9 billion acquisition of Southern Union being the largest MLP deal announced during the year. We expect additional need for growth capital for fiscal 2012, with accompanying MLP distribution growth of 6 percent to 8 percent.

One example that illustrates how growing North American production requires new pipeline infrastructure investment is the current crude oil supply glut in Cushing, Okla., a major hub for petroleum. Additional infrastructure is needed to alleviate the oversupply as transportation alternatives such as truck, rail or barge are logistically challenging and expensive. The ultimate resolution could take many forms, depending on the outcome of TransCanada’s Keystone XL project, which would serve to move crude oil out of Cushing to Texas refineries. Some relief is expected to come from Enterprise Product Partners’ and Enbridge Inc.’s planned reversal of the Seaway pipeline flow between Cushing and Houston.

Company Performance Review and Outlook

Our total assets increased from $1.4 billion on Nov. 30, 2010, to more than $1.5 billion on Nov. 30, 2011. This increase resulted primarily from net realized and unrealized gains on investments as well as $59 million in new equity and leverage proceeds. Our market-based total return was 7.7 percent and our NAV-based total return was 6.1 percent (both including the reinvestment of distributions) for the fourth fiscal quarter ended Nov. 30, 2011. For fiscal year 2011, our market-based total return was 15.3 percent and our NAV-based total return was 7.7 percent.

2011 Annual Report       1

---

During the fiscal year, our performance was positively impacted by refined product pipeline MLPs, driven by higher volumes and an increased tariff. Gathering and processing MLPs as well as natural gas pipeline MLPs benefited from growth projects, offset slightly by the performance of propane and gas storage MLPs.

We paid a distribution of $0.555 per common share ($2.22 annualized) to our stockholders on Nov. 30, 2011, an increase of 0.5 percent quarter-over-quarter and an increase of 2.8 percent year-over-year. This represented an annualized yield of 5.6 percent based on our fiscal year closing price of $39.35. Our distribution coverage (distributable cash flow divided by distributions) for the fiscal year was 108 percent. For tax purposes, distributions to stockholders for 2011 were 100 percent qualified dividend income.

We ended our fiscal year with leverage (including bank debt, senior notes and preferred stock) at 20.4 percent of total assets, below our long-term target of 25 percent. As of Nov. 30, 2011, our leverage had a weighted average maturity of 4.0 years and a weighted average cost of 5.0 percent, with over 80 percent at fixed rates. While our cost of leverage is higher than current short-term rates, we continue to believe a primarily fixed-rate strategy with laddered maturities enhances the predictability and sustainability of our distributable cash flow across interest rate environments.

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

Conclusion

We continue to expect substantial growth activity in our nation’s shales to drive infrastructure build-out. New domestic resources are becoming a more important part of our economy as we reduce dependence on foreign sources. We believe the investment merits of the energy infrastructure sector are particularly attractive as a result of this opportunity. We look forward to serving as your professional MLP investment adviser to navigate the course ahead, with a strategy anchored in quality midstream MLPs.

Sincerely,

The Managing Directors
Tortoise Capital Advisors, L.L.C.
The adviser to Tortoise Energy Infrastructure Corp.

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.

Overview

Tortoise Energy Infrastructure Corp.’s (the “Company”) goal is to provide a stable and growing distribution stream to our investors. We seek to provide our stockholders with an efficient vehicle to invest in the energy infrastructure sector. While we are a registered investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), we are not a “regulated investment company” for federal tax purposes. Our distributions do not generate unrelated business taxable income (“UBTI”) and our stock may therefore be suitable for holding by pension funds, IRAs and mutual funds, as well as taxable accounts. We invest primarily in MLPs through private and public market purchases. MLPs are publicly traded partnerships whose equity interests are traded in the form of units on public exchanges, such as the NYSE or NASDAQ. Tortoise Capital Advisors, L.L.C. serves as our investment adviser.

Company Update

Total assets increased approximately $65 million during the 4th quarter primarily as a result of higher market values of our MLP investments. Distribution increases from our MLP investments were in-line with our expectations and asset-based and other operating expenses declined from the previous quarter. Total leverage as a percent of total assets was increased slightly and we increased our quarterly distribution to $0.5550 per share. Additional information on these events and results of our operations are discussed in more detail 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, tax matters 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. Our Board of Directors considers our current and estimated future DCF in determining distributions to stockholders. Our Board of Directors reviews the distribution rate quarterly, and may adjust the quarterly distribution 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.

Determining DCF

DCF is simply distributions received from investments less expenses. The total distributions received from our investments include the amount received by us 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). Realized gains, expected tax benefits and deferred taxes are not included in our DCF.

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 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 on net investment income. A reconciliation of Net Investment Loss, before Income Taxes to DCF is included below.

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.

Management’s Discussion (Unaudited) (Continued)

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, many energy infrastructure companies are regulated and currently benefit from a tariff inflation escalation index of PPI + 2.65 percent. 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 4th quarter 2011 was approximately $24.3 million, representing a 6.6 percent increase as compared to 4th quarter 2010 and a 1.1 percent decrease as compared to 3rd quarter 2011. These changes reflect increases in per share distribution rates on our MLP investments and the distributions received from additional investments funded from equity and leverage proceeds, offset by the impact of trading activity wherein certain investments with higher current yields and lower expected future growth were sold and replaced with investments that had lower current yields and higher expected future growth.

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 and current taxes were an annualized 1.02 percent of average total assets for the 4th quarter 2011, a decrease of 0.06 percent as compared to the 4th quarter 2010 and unchanged as compared to 3rd quarter 2011. Advisory fees for the 4th quarter 2011 decreased 1.8 percent from 3rd quarter 2011 as a result of decreased average managed assets for the quarter. Yields on our MLP investments are currently below their 5-year historical average of approximately 7 percent. All else being equal, if MLP yields decrease and distributions remain constant or grow, MLP asset values will increase as will our managed assets and advisory fees. Other operating expenses decreased slightly as compared to 3rd quarter 2011.

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 $4.0 million for the 4th quarter 2011, unchanged as compared to 3rd quarter 2011.

The weighted average annual rate of our leverage at November 30, 2011 was 5.03 percent. This rate includes 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 and amended credit facility is disclosed below in Liquidity and Capital Resources and in our Notes to Financial Statements.

Distributable Cash Flow

For 4th quarter 2011, our DCF was approximately $16.3 million, an increase of 8.7 percent as compared to 4th quarter 2010 and a decrease of 1.3 percent or $212,000 as compared to 3rd quarter 2011. The changes are the net result of changes in distributions and expenses as outlined above. We declared a distribution of $15.4 million, or $0.5550 per share, during the quarter. This represents an increase of $0.0150 per share as compared to 4th quarter 2010 and an increase of $0.0025 per share as compared to 3rd quarter 2011.

Our distribution payout ratio as a percentage of DCF was 94.0 percent for 4th quarter 2011. Our goal is to pay what we believe to be sustainable distributions with any increases safely covered by earned DCF. 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 2011 YTD and 4th quarter 2011 (in thousands):

		2011 YTD				4th Qtr 2011
Net Investment Loss, before Income Taxes		$	(30,199	)		$	(6,399	)
Adjustments to reconcile to DCF:
Dividends paid in stock			7,310				1,572
Distributions characterized as return of capital			87,979				21,169
Distribution included in direct placement discount			238				—
Amortization of debt issuance costs			292				74
Current income tax expenses			(322	)			(68	)
DCF		$	65,298			$	16,348

We had total assets of $1.552 billion at year-end. Our total assets reflect the value of our investments, which are itemized in the Schedule of Investments. It also reflects cash, interest and other receivables, if any, and any expenses that may have been prepaid. During 4th quarter 2011, total assets increased $65 million. This change was primarily the result of a $73 million increase in the value of our investments as reflected by the change in realized and unrealized gains on investments (excluding return of capital on distributions) and an increase in current tax asset of $1.0 million, offset by net sales of approximately $1.9 million and a decrease in receivables for investments sold of $8 million.

We issued 110,424 shares of our common stock during the quarter under our at-the-market equity program and 70,021 shares under our dividend reinvestment plan for a net total of approximately $6.6 million. We are waiving our advisory fees on the net proceeds from shares issued under our at-the-market equity program for six months.

2011 Annual Report       5

Management’s Discussion (Unaudited) (Continued)

Total leverage outstanding at November 30, 2011 was $315.9 million, an increase of $19.5 million as compared to August 31, 2011. On an adjusted basis to reflect the payment of the 3rd quarter 2011 distribution at the beginning of the 4th quarter 2011, the increase is approximately $5.5 million. Outstanding leverage is comprised of approximately $195 million in senior notes, $73 million in preferred shares and $47.9 million outstanding under the credit facility, with 80.1 percent of leverage with fixed rates and a weighted average maturity of 4.0 years. Total leverage represented 20.4 percent of total assets at November 30, 2011, as compared to 19.9 percent as of August 31, 2011 and 19.4 percent as of November 30, 2010. Our leverage as a percent of total assets remains below our long-term target level of 25 percent, allowing the opportunity to add leverage when compelling investment opportunities arise. 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 $268 million is comprised of 73 percent private placement debt and 27 percent publicly traded preferred equity with a weighted average rate of 5.63 percent and remaining weighted average laddered maturity of approximately 4.6 years.

Our Mandatory Redeemable Preferred stock has an optional redemption feature allowing us to redeem all or a portion of the stock after December 31, 2012 and on or prior to December 31, 2013 at $10.10 per share. Any optional redemption after December 31, 2013 and on or prior to December 31, 2014 will be at $10.05 per share. Any redemption after December 31, 2014 will be at the liquidation preference amount of $10.00 per share.

We have used 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.

Taxation of our Distributions and Income Taxes

We invest in partnerships that generally have cash distributions in excess of their income for accounting and tax purposes. 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 (“E&P”). E&P is primarily comprised of the taxable income from MLPs with certain specified adjustments as reported on annual K-1s, fund operating expenses and net realized gains. If we have E&P, it is first allocated to the preferred shares and then to the common shares.

In the event we have E&P 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 15 percent QDI rate is currently effective through 2012. 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.

For tax purposes, distributions to common stockholders for the fiscal year ended 2011 were 100 percent qualified dividend income. 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 distributions to common stockholders for the fiscal year ended 2011 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 November 30, 2011, our investments are valued at $1.548 billion, with an adjusted cost of $887 million. The $661 million difference reflects unrealized gain 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 November 30, 2011, the balance sheet reflects a net deferred tax liability of approximately $306 million or $11.03 per share. Accordingly, our net asset value per share represents the amount which would be available for distribution to stockholders after payment of taxes.

As of November 30, 2011, we estimate utilizing all of our capital loss carryforwards and net operating losses prior to their expiration dates. For the fiscal year, we realized net capital gains which were offset, first by capital loss carryforwards and then by net operating losses. Tax payments are funded from investment earnings, fund assets or borrowings. Details of our taxes are disclosed in Note 5 in our Notes to Financial Statements.

Notes to Financial Statements  November 30, 2011

1. Organization

Tortoise Energy Infrastructure Corporation (the “Company”) was organized as a Maryland corporation on October 29, 2003, 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. The Company commenced operations on February 27, 2004. The Company’s stock is listed on the New York Stock Exchange under the symbol “TYG.”

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 30 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 private placement 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 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 information provided by 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.

During the year ended November 30, 2011, the Company reallocated the amount of 2010 investment income and return of capital it recognized based on the 2010 tax reporting information received from the individual MLPs. This reclassification amounted to a decrease in pre-tax net investment income of approximately $4,909,000 or $0.177 per share ($3,099,000 or $0.112 per share, net of deferred tax benefit); an increase in unrealized appreciation of investments of approximately $4,681,000 or $0.169 per share ($2,955,000 or $0.107 per share, net of deferred tax expense) and an increase in realized gains of approximately $228,000 or $0.008 per share ($144,000 or $0.005 per share, net of deferred tax expense) for the year ended November 30, 2011.

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 or 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 tax purposes, the Company’s distributions to common stockholders for the year ended November 30, 2011 were 100 percent qualified dividend income. For book purposes, the source of the Company’s distributions to common stockholders for the year ended November 30, 2011 was 100 percent return of capital.

Distributions to mandatory redeemable preferred (“MRP”) stockholders are paid on the first business day of each month and are accrued daily based on a fixed annual rate of 6.25 percent. The Company may not declare or pay distributions to its 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 MRP stockholders made during the year may differ from their ultimate characterization for federal income tax purposes. For tax purposes, the Company’s distributions to MRP stockholders for the year ended November 30, 2011 were 100 percent qualified dividend income. For book purposes, the source of the Company’s distributions to MRP stockholders for the year ended November 30, 2011 was 100 percent return of capital.

Notes to Financial Statements (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 and preferred stock are charged to additional paid-in capital when the stock is issued. Offering costs (excluding underwriter discounts and commissions) of $215,520 related to the issuance of common stock were recorded to additional paid-in capital during the year ended November 30, 2011. Debt issuance costs related to long-term debt obligations and MRP Stock are capitalized and amortized over the period the debt and MRP Stock is outstanding. The amounts of such capitalized costs for the Series H and Series I Notes issued in May 2011 were $13,104 and $8,736, respectively.

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 year ended November 30, 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.

I. Recent Accounting Pronouncement

In May 2011, the FASB issued ASU No. 2011-04 “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements” in GAAP and the International Financial Reporting Standards (“IFRSs”). ASU No. 2011-04 amends FASB ASC Topic 820, Fair Value Measurements and Disclosures, to establish common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with GAAP and IFRSs. ASU No. 2011-04 is effective for fiscal years beginning after December 15, 2011 and for interim periods within those fiscal years. Management is currently evaluating the impact of these amendments and does not believe they will have a material impact on the Company’s financial statements.

3. Concentration of Risk

Under normal circumstances, the Company intends to invest at least 90 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 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 25 percent of its assets in debt securities, which may include below investment grade securities. 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 and excluding any net deferred tax asset) minus accrued liabilities (other than net deferred tax liability, 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 contractually agreed to waive all fees due under the Investment Advisory Agreement related to the net proceeds received from the issuance of additional common stock under the at-the-market equity program for a six month period following the date of issuance.

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.

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 and cash purchase 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 November 30, 2011, are as follows:

Deferred tax assets:
State net operating loss carryforwards		$	293,780

Change in deferred tax liability due to change in overall tax rate			(714,836	)
Nondeductible payments on preferred stock			1,759,748
Dividends received deduction			(362,723	)
Total income tax expense		$	42,199,352

For the year ended November 30, 2011, the components of income tax expense include the following:

Current tax expense (benefit)
Federal		$	8,746,227
State			736,141
AMT			(605,833	)
Foreign (reflects a federal tax benefit in deferred tax expense)			73,920

State (net of federal tax benefit)			1,677,779
Total deferred tax expense			33,248,897
Total income tax expense		$	42,199,352

As of November 30, 2011, the aggregate cost of securities for federal income tax purposes was $717,686,964. The aggregate gross unrealized appreciation for all securities in which there was an excess of fair value over tax cost was $838,338,614, the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over fair value was $8,119,950 and the net unrealized appreciation was $830,218,664.

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.

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 during the year ended November 30, 2011.

7. Investment Transactions

For the year ended November 30, 2011, the Company purchased (at cost) and sold securities (proceeds received) in the amount of $315,345,533 and $269,306,418 (excluding short-term debt securities), respectively.

8. Long-Term Debt Obligations

The Company has $194,975,000 aggregate principal amount of private senior notes, Series E, Series F, Series G, Series H, and Series I (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 shares; (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 E, Series F, Series G, and Series I Notes accrue interest at fixed rates and the Series H Notes accrue interest at an annual rate that resets each quarter based on the 3-month LIBOR plus 1.35 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 November 30, 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. The estimated fair value of the Series H 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 November 30, 2011.

							Notional/
		Maturity		Interest			Carrying			Estimated
Series		Date		Rate			Amount			Fair Value
Series E		April 10, 2015		6.11	%		$	110,000,000		$	123,480,126
Series F		December 21, 2012		4.50	%			29,975,000			30,964,695
Series G		December 21, 2016		5.85	%			30,000,000			34,289,778
Series H		May 12, 2014		1.80	%(1)			15,000,000			15,000,000
Series I		May 12, 2018		4.35	%			10,000,000			10,550,583
							$	194,975,000		$	214,285,182

(1)	Floating rate; rate effective for period from November 12, 2011 through February 12, 2012. The weighted-average interest rate for the period from May 12, 2011 (date of issuance) through November 30, 2011 was 1.64 percent.

9. Preferred Stock

The Company has 10,000,000 shares of preferred stock authorized. Of that amount, the Company has 7,475,000 authorized shares of Mandatory Redeemable Preferred (“MRP”) Stock and 7,300,000 shares are outstanding at November 30, 2011. The MRP Stock has a liquidation value of $10.00 per share plus any accumulated but unpaid distributions, whether or not declared, and is mandatorily redeemable on December 31, 2019. The MRP Stock pays cash distributions on the first business day of each month at an annual rate of 6.25 percent. The shares of MRP Stock trade on the NYSE under the symbol “TYG Pr A.”

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.

At November 30, 2011, the estimated fair value of the MRP Stock is based on the closing market price of $10.705 per share. The following table shows the mandatory redemption date, fixed rate, number of shares outstanding, aggregate liquidation preference and estimated fair value as of November 30, 2011.

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 November 30, 2011, the Company was in compliance with asset coverage covenants and basic maintenance covenants for its MRP Stock.

10. Credit Facility

On June 20, 2010, the Company entered into an amendment to its credit facility that extended the credit facility through June 20, 2011. U.S. Bank, N.A. serves as a lender and the lending syndicate agent on behalf of other lenders participating in the credit facility. The terms of the amendment provided for an unsecured revolving credit facility of $70,000,000. On March 9, 2011, the Company entered into an amendment that increased the amount available under its unsecured revolving credit facility to $85,000,000. During the extension, outstanding balances accrued interest at a variable annual rate equal to one-month LIBOR plus 1.25 percent and unused portions of the credit facility accrued a non-usage fee equal to an annual rate of 0.20 percent.

On June 20, 2011, the Company entered into an amendment to its credit facility that extends the credit facility through June 18, 2012. The terms of the amendment provide for an unsecured revolving credit facility of $85,000,000. During the extension, outstanding balances generally will accrue interest at a variable annual 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.

The average principal balance and interest rate for the period during which the credit facility was utilized during the year ended November 30, 2011 was approximately $46,100,000 and 1.48 percent, respectively. At November 30, 2011, the principal balance outstanding was $47,900,000 at an interest rate of 1.52 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 November 30, 2011, the Company was in compliance with the terms of the credit facility.

11. Common Stock

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Tortoise Energy Infrastructure Corporation

We have audited the accompanying statement of assets and liabilities of Tortoise Energy Infrastructure Corporation (the Company), including the schedule of investments, as of November 30, 2011, and the related statements of operations and cash flows for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of November 30, 2011, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Tortoise Energy Infrastructure Corporation at November 30, 2011, the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Privacy Policy

In order to conduct its business, the Company collects and maintains certain nonpublic personal information about its stockholders of record with respect to their transactions in shares of the Company’s securities. This information includes the stockholder’s address, tax identification or Social Security number, share balances, and distribution elections. We do not collect or maintain personal information about stockholders whose share balances of our securities are held in “street name” by a financial institution such as a bank or broker.

We do not disclose any nonpublic personal information about you, the Company’s other stockholders or the Company’s former stockholders to third parties unless necessary to process a transaction, service an account, or as otherwise permitted by law.

To protect your personal information internally, we restrict access to nonpublic personal information about the Company’s stockholders to those employees who need to know that information to provide services to our stockholders. We also maintain certain other safeguards to protect your nonpublic personal information.

Automatic Dividend Reinvestment and Cash Purchase Plan

The Company’s Automatic Dividend Reinvestment and Cash Purchase Plan (the “Plan”) allows participating common stockholders to reinvest distributions, including dividends, capital gains and return of capital in additional shares of the Company’s common stock and allows registered holders of the Company’s common stock to make optional cash investments, in accordance with the Plan, on a monthly basis.

If a stockholder’s shares are registered directly with the Company or with a brokerage firm that participates in the Company’s Plan, all distributions are automatically reinvested for stockholders by the Agent in additional shares of common stock of the Company (unless a stockholder is ineligible or elects otherwise). Stockholders holding shares that participate in the Plan in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. Stockholders who elect not to participate in the Plan will receive all distributions payable in cash paid by check mailed directly to the stockholder of record (or, if the shares are held in street or other nominee name, then to such nominee) by Computershare, as dividend paying agent. Distributions subject to tax (if any) are taxable whether or not shares are reinvested.

Any single investment pursuant to the cash purchase option under the Plan must be in an amount of at least $100 and may not exceed $5,000 per month unless a request for waiver has been granted. A request for waiver should be directed to the Company at 1-866-362-9331 and the Company has the sole discretion to grant any requested waiver. Optional cash investments may be delivered to the Agent by personal check, by automatic or electronic bank account transfer or by online access at www.computershare.com. The Company reserves the right to reject any purchase order. Stockholders who hold shares in street or other nominee name who want to participate in optional cash investments should contact their broker, bank or other nominee and follow their instructions. There is no obligation to make an optional cash investment at any time, and the amount of such investments may vary from time to time. Optional cash investments must be received by the Agent no later than two business days prior to the monthly investment date (the “payment date”) for purchase of common shares on the next succeeding purchase date under the Plan. Scheduled optional cash purchases may be cancelled or refunded upon a participant’s written request received by the Agent at least two business days prior to the purchase date. Participants will not be able to instruct the Agent to purchase common shares at a specific time or at a specific price.

If on the distribution payment date or the purchase date for optional cash investments, the net asset value per share of the common stock is equal to or less than the market price per share of common stock plus estimated brokerage commissions, the Company will issue additional shares of common stock to participants. The number of shares will be determined by the greater of the net asset value per share or 95 percent of the

2011 Annual Report       21

Additional Information (Unaudited) (Continued)

market price. Otherwise, shares generally will be purchased on the open market by the Agent as soon as possible following the payment date or purchase date, but in no event later than 30 days after such date except as necessary to comply with applicable law. There are no brokerage charges with respect to shares issued directly by the Company as a result of distributions payable either in shares or in cash or as a result of optional cash investments. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Agent’s open-market purchases in connection with the reinvestment of distributions or optional cash investments. If a participant elects to have the Agent sell part or all of his or her common stock and remit the proceeds, such participant will be charged a transaction fee of $15.00 plus his or her pro rata share of brokerage commissions on the shares sold.

Participation is completely voluntary. Stockholders may elect not to participate in the Plan, and participation may be terminated or resumed at any time without penalty, by giving notice in writing, by telephone or Internet to Computershare, the Plan Agent, at the address set forth below. Such termination will be effective with respect to a particular distribution if notice is received prior to such record date.

Additional information about the Plan may be obtained by writing to Computershare Trust Company, N.A, P.O. Box 43078, Providence, R.I. 02940-3078. You may also contact Computershare by phone at (800) 426-5523 or visit their Web site at www.computershare.com.

Approval of the Investment Advisory Agreement

In approving the renewal of the Investment Advisory Agreement in November 2011, the directors who are not “interested persons” (as defined in the Investment Company Act of 1940) of the Company (“Independent Directors”) requested and received extensive data and information from the Adviser concerning the Company and the services provided to it by the Adviser under the Investment Advisory Agreement. In addition, the Independent Directors requested and received data and information from the Adviser, which also included information from independent, third-party sources, regarding the factors considered in their evaluation.

Factors Considered

The Independent Directors considered and evaluated all the information provided by the Adviser. The Independent Directors did not identify any single factor as being all-important or controlling, and each Independent Director may have attributed different levels of importance to different factors. In deciding to renew the agreement, the Independent Directors’ decision was based on the following factors.

Nature, Extent and Quality of Services Provided. The Independent Directors considered information regarding the history, qualification and background of the Adviser and the individuals responsible for the Adviser’s investment program, the adequacy of the number of the Adviser personnel and other Adviser resources and plans for growth, use of affiliates of the Adviser, and the particular expertise with respect to energy infrastructure companies, MLP markets and financing (including private financing). The Independent Directors concluded that the unique nature of the Company and the specialized expertise of the Adviser in the niche market of MLPs made it uniquely qualified to serve as the advisor. Further, the Independent Directors recognized that the Adviser’s commitment to a long-term investment horizon correlated well to the investment strategy of the Company.

Investment Performance of the Company and the Adviser, Costs of the Services To Be Provided and Profits To Be Realized by the Adviser and its Affiliates from the Relationship, and Fee Comparisons. The Independent Directors reviewed and evaluated information regarding the Company’s performance (including quarterly, last twelve months, and from inception) and the performance of the other Adviser accounts (including other investment companies), and information regarding the nature of the markets during the performance period, with a particular focus on the MLP sector. The Independent Directors also considered the Company’s performance as compared to comparable closed-end funds for the relevant periods.

The Adviser provided detailed information concerning its cost of providing services to the Company, its profitability in managing the Company, its overall profitability, and its financial condition. The Independent Directors reviewed with the Adviser the methodology used to prepare this financial information. This financial information regarding the Adviser is considered in order to evaluate the Adviser’s financial condition, its ability to continue to provide services under the Investment Advisory Agreement, and the reasonableness of the current management fee, and was, to the extent possible, evaluated in comparison to other closed-end funds with similar investment objectives and strategies.

The Independent Directors considered and evaluated information regarding fees charged to, and services provided to, other investment companies advised by the Adviser (including the impact of any fee waiver or reimbursement arrangements and any expense reimbursement arrangements), fees charged to separate institutional accounts by the Adviser, and comparisons of fees of closed-end funds with similar investment objectives and strategies, including other MLP investment companies, to the Company. The Independent Directors concluded that the fees and expenses that the Company is paying under the Investment Advisory Agreement are reasonable given the quality of services provided under the Investment Advisory Agreement and that such fees and expenses are comparable to, and in many cases lower than, the fees charged by advisers to comparable funds.

Economies of Scale. The Independent Directors considered information from the Adviser concerning whether economies of scale would be realized as the Company grows, and whether fee levels reflect any economies of scale for the benefit of the Company’s stockholders. The Independent Directors concluded that economies of scale are difficult to measure and predict overall. Accordingly, the Independent Directors reviewed other information, such as year-over-year profitability of the Adviser generally, the profitability of its management of the Company specifically, and the fees of competitive funds not managed by the Adviser over a range of asset sizes. The Independent Directors concluded the Adviser is appropriately sharing any economies of scale through its competitive fee structure and through reinvestment in its business to provide stockholders additional content and services.

Collateral Benefits Derived by the Adviser. The Independent Directors reviewed information from the Adviser concerning collateral benefits it receives as a result of its relationship with the Company. They concluded that the Adviser generally does not use the Company’s or stockholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them.

The Independent Directors did not, with respect to their deliberations concerning their approval of the continuation of the Investment Advisory Agreement, consider the benefits the Adviser may derive from relationships the Adviser may have with brokers through soft dollar arrangements because the Adviser does not employ any such arrangements in rendering its advisory services to the Company. Although the Adviser may receive research from brokers with whom it places trades on behalf of clients, the Adviser does not have soft dollar arrangements or understandings with such brokers regarding receipt of research in return for commissions.

Conclusions of the Directors

As a result of this process, the Independent Directors, assisted by the advice of legal counsel that is independent of the Adviser, taking into account all of the factors discussed above and the information provided by the Adviser, unanimously concluded that the Investment Advisory Agreement between the Company and the Adviser is fair and reasonable in light of the services provided and should be renewed.

Item 2. Code of Ethics.

The Registrant has adopted a code of ethics that applies to the Registrant’s Chief Executive Officer and its Chief Financial Officer. The Registrant has not made any amendments to this code of ethics during the period covered by this report, except that Exhibit A to the Code was updated to reflect the names of the current Principal Executive Officer and Principal Financial Officer. The Registrant has not granted any waivers from any provisions of this code of ethics during the period covered by this report.

Item 3. Audit Committee Financial Expert.

The Registrant’s Board of Directors has determined that there is at least one “audit committee financial expert” serving on its audit committee. Mr. Conrad Ciccotello is the “audit committee financial expert” and is considered to be “independent” as each term is defined in Item 3 of Form N-CSR. In addition to his experience overseeing or assessing the performance of companies or public accountants with respect to the preparation, auditing or evaluation of financial statements, Mr. Ciccotello has a Ph.D. in Finance.

Item 4. Principal Accountant Fees and Services.

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

The audit committee has adopted pre-approval policies and procedures that require the audit committee to pre-approve (i) the selection of the Registrant’s independent registered public accounting firm, (ii) the engagement of the independent registered public accounting firm to provide any non-audit services to the Registrant, (iii) the engagement of the independent registered public accounting firm to provide any non-audit services to the Adviser or any entity controlling, controlled by, or under common control with the Adviser that provides ongoing services to the Registrant, if the engagement relates directly to the operations and financial reporting of the Registrant, and (iv) the fees and other compensation to be paid to the independent registered public accounting firm. The Chairman of the audit committee may grant the pre-approval of any engagement of the independent registered public accounting firm for non-audit services of less than $10,000, and such delegated pre-approvals will be presented to the full audit committee at its next meeting. Under certain limited circumstances, pre-approvals are not required under securities law regulations for certain non-audit services below certain de minimus thresholds. Since the adoption of these policies and procedures, the audit committee has pre-approved all audit and non-audit services provided to the Registrant by the principal accountant. None of these services provided by the principal accountant were approved by the audit committee pursuant to the de minimus exception under Rule 2.01(c)(7)(i)(C) or Rule 2.01(c)(7)(ii) of Regulation S-X. All of the principal accountant’s hours spent on auditing the Registrant’s financial statements were attributed to work performed by full-time permanent employees of the principal accountant.

---

In the Registrant’s fiscal years ended November 30, 2011 and 2010, the Adviser paid approximately $0 and $88,000 in fees, respectively, for research and consultations relating to fund structure, tax and accounting, and audit-related fees relating to closed-end management investment companies prior to its initial public offerings. These non-audit services were not required to be preapproved by the Registrant’s audit committee. No entity controlling, controlled by, or under common control with the Adviser that provides ongoing services to the Registrant, has paid to, or been billed for fees by, the principal accountant for non-audit services rendered to the Adviser or such entity during the Registrant’s last two fiscal years. The audit committee has considered whether the principal accountant’s provision of services (other than audit services) to the Registrant, the Adviser or any entity controlling, controlled by, or under common control with the Adviser that provides services to the Registrant is compatible with maintaining the principal accountant’s independence in performing audit services.

Item 5. Audit Committee of Listed Registrants.

The Registrant has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, and is comprised of Mr. Conrad S. Ciccotello, Mr. John R. Graham and Mr. Charles E. Heath.

Item 6. Schedule of Investments.

Schedule of Investments is included as part of the report to shareholders filed under Item 1.

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

Copies of the proxy voting policies and procedures of the Registrant and the Adviser are attached hereto as Exhibit 99.VOTEREG and Exhibit 99.VOTEADV, respectively.

Item 8. Portfolio Managers of Closed-End Management Investment Companies.

Unless otherwise indicated, information is presented as of November 30, 2011.

Portfolio Managers

As of the date of this filing, management of the Registrant’s portfolio is the responsibility of a team of portfolio managers consisting of H. Kevin Birzer, Terry Matlack, David J. Schulte, Zachary A. Hamel and Kenneth P. Malvey, all of whom are Managers of the Adviser, comprise the investment committee of the Adviser and share responsibility for such investment management. All decisions to invest in a portfolio company must be approved by the unanimous decision of the Adviser’s investment committee and any one member of the Adviser’s investment committee can require the Adviser to sell a portfolio company or can veto the investment committee’s decision to invest in a portfolio company.

Material Conflicts of Interest

Conflicts of interest may arise from the fact that the Adviser and its affiliates carry on substantial investment activities for other clients, in which the Registrant has no interest, some of which may have investment strategies similar to the Registrant. The Adviser or its affiliates may have financial incentives to favor certain of these accounts over the Registrant. For example, the Adviser may have an incentive to allocate potentially more favorable investment opportunities to other funds and clients that pay the Adviser an incentive or performance fee. Performance and incentive fees also create the incentive to allocate potentially riskier, but potentially better performing, investments to such funds and other clients in an effort to increase the incentive fee. The Adviser also may have an incentive to make investments in one fund, having the effect of increasing the value of a security in the same issuer held by another fund, which, in turn, may result in an incentive fee being paid to the Adviser by that other fund. Any of their proprietary accounts or other customer accounts may compete with the Registrant for specific trades. The Adviser or its affiliates may give advice and recommend securities to, or buy or sell securities for, other accounts and customers, which advice or securities recommended may differ from advice given to, or securities recommended or bought or sold for, the Registrant, even though their investment objectives may be the same as, or similar to, the Registrant’s objectives. When two or more clients advised by the Adviser or its affiliates seek to purchase or sell the same publicly traded securities, the securities actually purchased or sold will be allocated among the clients on a good faith equitable basis by the Adviser in its discretion and in accordance with the clients’ various investment objectives and the Adviser’s procedures. In some cases, this system may adversely affect the price or size of the position the Registrant may obtain or sell. In other cases, the Registrant’s ability to participate in volume transactions may produce better execution for it.

The Adviser also serves as investment adviser for five other publicly traded management investment companies, all of which invest in the energy sector.

Situations may occur when the Registrant could be disadvantaged because of the investment activities conducted by the Adviser and its affiliates for their other accounts. Such situations may be based on, among other things, the following: (1) legal or internal restrictions on the combined size of positions that may be taken for the Registrant or the other accounts, thereby limiting the size of the Registrant’s position; (2) the difficulty of liquidating an investment for the Registrant or the other accounts where the market cannot absorb the sale of the combined position; or (3) limits on co-investing in private placement securities under the Investment Company Act of 1940. The Registrant’s investment opportunities may be limited by affiliations of the Adviser or its affiliates with energy infrastructure companies.

Under the Investment Company Act of 1940, the Registrant and its affiliated companies may be precluded from co-investing in negotiated private placements of securities. As such, the Registrant will not co-invest with its affiliates in negotiated private placement transactions. The Adviser will observe a policy for allocating negotiated private investment opportunities among its clients that takes into account the amount of each client’s available cash and its investment objectives. These allocation policies may result in the allocation of investment opportunities to an affiliated company rather than to the Registrant.

To the extent that the Adviser sources and structures private investments in master limited partnerships (“MLPs”), certain employees of the Adviser may become aware of actions planned by MLPs, such as acquisitions, which may not be announced to the public. It is possible that the Registrant could be precluded from investing in or selling securities of an MLP about which the Adviser has material, non-public information; however, it is the Adviser’s intention to ensure that any material, non-public information available to certain employees of the Adviser is not shared with the employees responsible for the purchase and sale of publicly traded MLP securities or to confirm prior to receipt of any material non-public information that the information will shortly be made public. The Registrant’s investment opportunities also may be limited by affiliations of the Adviser or its affiliates with energy infrastructure companies.

The Adviser and its principals, officers, employees, and affiliates may buy and sell securities or other investments for their own accounts and may have actual or potential conflicts of interest with respect to investments made on the Registrant’s behalf. As a result of differing trading and investment strategies or constraints, positions may be taken by principals, officers, employees, and affiliates of the Adviser that are the same as, different from, or made at a different time than positions taken for the Registrant. Further, the Adviser may at some time in the future, manage additional investment funds with the same investment objective as the Registrant’s.

Compensation

None of Messrs. Birzer, Hamel, Malvey, Matlack or Schulte receives any direct compensation from the Registrant or any other of the managed accounts reflected in the table above. All such accounts are managed by the Adviser or Fountain Capital. Messrs. Birzer, Hamel, Malvey, Matlack and Schulte are full-time employees of the Adviser and receive a fixed salary for the services they provide. They are also eligible for an annual cash bonus based on the Adviser’s earnings and the satisfaction of certain other conditions. Additional benefits received by Messrs. Birzer, Hamel, Malvey, Matlack and Schulte are normal and customary employee benefits generally available to all salaried employees. Each of Messrs. Birzer, Hamel, Malvey, Matlack and Schulte own an equity interest in Tortoise Holdings, LLC which wholly owns the Adviser, and each thus benefits from increases in the net income of the Adviser.
