June 15, 2012

Dear Fellow Stockholders,

Macro uncertainty dominated the last month of our second fiscal quarter ended May 31, 2012, with European turmoil taking center stage. This volatility reversed the year’s earlier broader market gains, with shorter-term market noise not allowing time for investors to differentiate quality. As a result, equity markets, including the energy sector as a whole, were down in the month of May, as evidenced by the S&P 500 ^® and S&P 500 Energy ^® total return of negative 6.0 percent and negative 10.2 percent, respectively.

The short-term market environment also impacted master limited partnerships (MLPs) across the board. However, midstream MLPs have demonstrated their resiliency across several cycles and we continue to believe their businesses remain strong, anchored in predictable distributions. Due to multi-year hedges, upstream MLPs continued to deliver consistent distributions despite the commodity price volatility experienced during the quarter as the price of oil fell by over 19 percent to $86.53 and the price of natural gas reached decade lows.

Master Limited Partnership Sector Review

The Tortoise MLP Index ^® posted a total return of negative 9.1 percent and positive 1.7 percent for the three months and six months ended May 31, 2012, respectively. Pipeline MLPs performed well on a relative basis, as evidenced by the Tortoise Long-Haul Pipeline MLP Index’s total return of negative 8.0 percent and positive 4.8 percent, respectively, for the same periods. Due to commodity price volatility, E&P MLPs, as represented by the Tortoise Upstream MLP Index, had a total return of negative 11.0 percent and negative 7.0 percent, respectively, for the same periods.

We remain confident in our distribution growth expectations for midstream MLPs of 6 to 8 percent for 2012, as heightened activity in both M&A and internal growth projects continue. We just witnessed three years of more than $100 billion of acquisitions and internal growth projects, and we anticipate another $100 billion over the next three years. M&A activity remains elevated in 2012 with approximately $22.4 billion fiscal year-to-date, including $17.4 billion and $2.9 billion in pipeline and upstream related acquisitions, respectively.

Also driving activity are significant internal growth projects as the continued emergence of the shale plays is highlighting the crude oil and natural gas production growth potential in both the U.S. and Canada. This production growth is also presenting numerous opportunities for MLPs to build out supporting pipeline, processing and fractionation infrastructure.

Capital markets remain supportive of this activity, with MLPs issuing over $10.7 billion of equity and $15.5 billion of debt for the fiscal year-to- date, consistent with 2010 and 2011 levels at this point in the year. Of this, the total issuance of pipeline MLPs and E&P MLPs was approximately $17.7 billion and $5.1 billion, respectively.

Fund Performance Review

Our total assets decreased from $229.9 million on Feb. 29, 2012, to $202.7 million as of our second fiscal quarter end, resulting primarily from market depreciation of our investments. Our market-based total return was negative 5.6 percent and positive 3.4 percent (both including the reinvestment of distributions) for the three months and six months ended May 31, 2012, respectively.

We paid a distribution of $0.3875 per common share ($1.55 annualized) to our stockholders on June 1, 2012, an increase of 0.6 percent from our prior quarterly distribution. This distribution represented an annualized yield of 6.4 percent based on our fiscal quarter closing price of $24.09. Our distribution coverage (distributable cash flow divided by distributions) for the second fiscal quarter was 105.8 percent. For tax purposes, we currently expect 80 to 100 percent of TYN’s 2012 distributions to be characterized as qualified dividend income, or QDI, with the remainder as return of capital. A final determination of the characterization will be made in January 2013.

We ended the second fiscal quarter with leverage at 14.8 percent of total assets, which had a weighted average maturity of 5.3 years, a weighted average cost of 2.4 percent, and over 83 percent at fixed rates.

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

Conclusion

We will continue to monitor the impact of the overall macroeconomic environment, but believe these assets, critical to our energy needs, are attractive to investors in both growth periods and uncertain environments.

Sincerely,
The Managing Directors
Tortoise Capital Advisors, L.L.C.

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 North American Energy Corp.’s (“TYN” or the “Company”) investment objective is to seek a high level of total return for our stockholders, with an emphasis on distribution income paid to stockholders. Our investment strategy requires us to invest at least 80 percent of our total assets in equity securities of companies in the energy sector with their primary operations in North America, including energy infrastructure, oil and gas exploitation and energy shipping companies. The equity securities of the energy companies purchased by TYN consist primarily of interests in MLPs. MLPs are publicly traded partnerships whose equity interests are traded in the form of units on public exchanges, such as the NYSE or NASDAQ. We invest primarily in MLPs through public market and private purchases. 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 typically 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. Tortoise Capital Advisors, L.L.C. serves as our investment adviser.

Company Update

Total assets decreased approximately $27.2 million during the 2nd quarter primarily as a result of decreased market values of our MLP investments. Average total assets for the quarter increased slightly as compared to 1st quarter 2012, resulting in increased asset-based expenses. Distribution increases from our MLP investments were in-line with our expectations. Total leverage as a percent of total assets increased slightly during the quarter and we increased our quarterly distribution to $0.3875 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 has adopted a policy of declaring what it believes to be sustainable distributions. In determining distributions, our Board of Directors considers a number of current and anticipated factors, including, among others, distributable cash flow, realized and unrealized gains, leverage amounts and rates, current and deferred taxes payable, and potential volatility in returns from our investments and the overall market. Over the long term, we expect to distribute substantially all of our DCF to holders of common stock. Our Board of Directors reviews the distribution rate quarterly, and may adjust the quarterly distribution throughout the year.

Determining DCF

DCF is 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. Current income taxes include taxes paid on net investment income of the Company, in addition to foreign taxes, if any. Taxes incurred from realized gains on the sale of investments, expected tax benefits and deferred taxes are not included in 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, including expense reimbursement, as disclosed in the Statement of Operations, the DCF calculation reflects interest expense, realized and unrealized gains (losses) on interest rate swap settlements, other leverage expenses, and current taxes paid on net investment income. A reconciliation of Net Investment Loss, before Income Taxes to DCF is included below.

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 anticipation of its growth rate, and its risk relative to other potential investments.

We concentrate on investments 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.

Total distributions received from our investments for the 2nd quarter 2012 was approximately $3.4 million. This represents a 0.8 percent increase as compared to 1st quarter 2012 and an increase of approximately 1.5 percent as compared to 2nd quarter 2011. These changes reflect increases in per share distribution rates on our MLP investments, 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 1.22 percent of average total assets for the 2nd quarter 2012 as compared to 1.18 percent for the 2nd quarter 2011 and 1.22 percent for the 1st quarter 2012. The change from 2nd quarter 2011 is primarily the result of a reduction in the fee waiver of 0.05 percent that occurred during 1st quarter 2012.

Advisory fees for the 2nd quarter 2012 increased 2.6 percent from 1st quarter 2012 as a result of increased average managed assets for the quarter as discussed above. Other operating expenses decreased slightly as compared to 1st quarter 2012.

Leverage costs consist of two major components: (1) the direct interest expense, which will vary from period to period as our margin borrowing facility has a variable interest rate, and (2) the realized and unrealized gain or loss on our interest rate swap settlements. Detailed information on our margin borrowing facility is included in the Liquidity and Capital Resources section below.

Total leverage costs for DCF purposes were approximately $189,000 for the 2nd quarter 2012 compared to $184,000 for the 1st quarter 2012. Our average annualized total cost of leverage, including interest rate swaps, was 2.39 percent as of May 31, 2012.

As indicated in Note 9 of our Notes to Financial Statements, we have entered into $25 million notional amount of interest rate swap contracts with The Bank of Nova Scotia in an attempt to reduce a portion of the interest rate risk arising from our leveraged capital structure. TYN has agreed to pay The Bank of Nova Scotia a fixed rate while receiving a floating rate based upon the 1-month U.S. Dollar London Interbank Offered Rate (“LIBOR”). The spread between the fixed swap rate and LIBOR is reflected in our Statement of Operations as a realized or unrealized gain when LIBOR exceeds the fixed rate (The Bank of Nova Scotia pays TYN the net difference) or a realized or unrealized loss when the fixed rate exceeds LIBOR (TYN pays The Bank of Nova Scotia the net difference). The interest rate swap contracts have a weighted average fixed rate of 1.70 percent and weighted average remaining maturity of approximately 6.3 years at May 31, 2012. This swap arrangement effectively fixes the cost of approximately 83 percent of our outstanding leverage as of May 31, 2012 over the remaining swap period.

Interest accrues on the margin facility at a rate equal to 1-month LIBOR plus 0.85 percent and unused balances are subject to a fee of 0.25 percent. The annual rate of leverage may vary in future periods as a result of changes in LIBOR, the utilization of our margin facility, and maturity of our interest rate swap contracts. Additional information on our leverage is disclosed below in Liquidity and Capital Resources and in our Notes to Financial Statements.

Distributable Cash Flow

For 2nd quarter 2012, our DCF was approximately $2.6 million, an increase of 0.5 percent as compared to 1st quarter 2012. The change is the net result of changes to distributions and expenses as outlined above. We declared a distribution of $2.4 million, or $0.3875 per share, during the quarter. This represents an increase of $0.0125 per share as compared 2nd quarter 2011 and an increase of $0.0025 per share as compared to 1st quarter 2012.

Our distribution coverage ratio was 105.8 percent for 2nd quarter 2012. Our goal is to pay what we believe to be sustainable distributions with any increases safely covered by earned DCF. A distribution coverage ratio of greater than 100 percent provides flexibility for on-going management of the portfolio, changes in leverage costs and other expenses. An on-going distribution coverage ratio of less than 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 2012 YTD and 2nd quarter 2012 (in thousands):

		2012 YTD		2nd Qtr 2012
Net Investment Loss, before Income Taxes		$	(1,570	)			$	(1,280	)
Adjustments to reconcile to DCF:
Dividends paid in stock			412					211
Distributions characterized as return of capital			6,489					3,743
Interest rate swap expenses			(183	)				(93	)
DCF		$	5,148				$	2,581

Management’s Discussion  (Unaudited) (Continued)

Liquidity and Capital Resources

We had total assets of $203 million 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 receivables and any expenses that may have been prepaid. During 2nd quarter 2012, total assets decreased by approximately $27.2 million. This change was primarily the result of a $26.9 million decrease in the value of our investments as reflected by the change in realized and unrealized gains on investments (excluding return of capital on distributions).

Total leverage outstanding at May 31, 2012 was $30.0 million, a decrease of $0.3 million as compared to February 29, 2012. Total leverage represented 14.8 percent of total assets at May 31, 2012, an increase from 13.2 percent of total assets at February 29, 2012 and an increase from 12.8 percent of total assets at May 31, 2011. Our leverage as a percent of total assets remains below our long-term target level of 20 percent of total assets. This allows the opportunity to add leverage when compelling investment opportunities arise. Temporary increases to up to 25 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.

We have used leverage to acquire securities 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 8 in the Notes to Financial Statements. Our coverage ratio is 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 preferred shares (if any) 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. We currently estimate that 80 to 100 percent of 2012 distributions will be characterized as qualified dividend inc ome for tax purposes, with the remaining percentage, if any, characterized as return of capital. A final determination of the characterization will be made in January 2013.

The unrealized gain or loss we have in the portfolio is reflected in the Statement of Assets and Liabilities. At May 31, 2012, our investments are valued at $202.6 million, with an adjusted cost of $138.4 million. The $64.2 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 primarily upon unrealized gains (losses) on investments, realized gains (losses) on investments, capital loss carryforwards and net operating losses. At May 31, 2012, the balance sheet reflects a net deferred tax liability of approximately $19.0 million or $3.02 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.

As of November 30, 2011, we had approximately $15 million in capital loss carryforwards and $11 million in net operating losses. To the extent we have taxable income that is not offset by either capital loss carryforwards or net operating losses, we will owe federal and state income taxes. Tax payments can be funded from investment earnings, fund assets or borrowings. Details of our taxes are disclosed in Note 5 in our Notes to Financial Statements.

2012 2nd Quarter Report       11

N otes to F inancial  S tatements (Unaudited) May 31, 2012

1. Organization

Tortoise North American Energy Corporation (the “Company”) was organized as a Maryland corporation on January 13, 2005, 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 distribution income paid to stockholders. The Company seeks to provide its stockholders with a vehicle to invest in a portfolio consisting primarily of publicly traded U.S. master limited partnerships (“MLPs”), including oil and gas exploitation, energy infrastructure and energy shipping companies. The Company commenced operations on October 31, 2005. The Company’s stock is listed on the New York Stock Exchange under the symbol “TYN.”

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 and 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.

The Company generally values its interest rate swap contracts using industry-accepted models which discount the estimated future cash flows based on the stated terms of the interest rate swap agreement by using interest rates currently available in the market, or based on dealer quotations, if available.

C. Foreign Currency Translation

For foreign currency, investments in foreign securities, and other assets and liabilities denominated in a foreign currency, the Company translates these amounts into U.S. dollars on the following basis:

	(1)	market value of investment securities, assets and liabilities at the current rate of exchange on the valuation date and
	(2)	purchases and sales of investment securities, income and expenses at the relevant rates of exchange on the respective dates of such transactions.

The Company does not isolate that portion of gains and losses on investments that is due to changes in the foreign exchange rates from that which is due to changes in market prices of equity securities.

D. Foreign Withholding Taxes

The Company may be subject to taxes imposed by countries in which it invests with respect to its investment in issuers existing or operating in such countries. Such taxes are generally based on income earned. The Company accrues such taxes when the related income is earned.

E. 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 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.

For the period from December 1, 2010 through November 30, 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 had estimated approximately 12 percent of total distributions as investment income and approximately 88 percent as return of capital.

Subsequent to November 30, 2011, the Company reallocated the amount of investment income and return of capital it recognized for the period from December 1, 2010 through November 30, 2011 based on the 2011 tax reporting information received from the individual MLPs. This reclassification amounted to a decrease in pre-tax net investment income of approximately $920,000 or $0.146 per share ($578,000 or $0.092 per share, net of deferred tax benefit), an increase in unrealized appreciation of investments of approximately $806,000 or $0.128 per share ($506,000 or $0.080 per share, net of deferred tax expense), and an increase in realized gains of approximately $114,000 or $0.018 per share ($72,000 or $0.012 per share, net of deferred tax expense) for the period from December 1, 2011 through May 31, 2012.

Subsequent to the period ended February 29, 2012, the Company reallocated the amount of investment income and return of capital it recognized in the current fiscal year based on its revised 2012 estimates, after considering the final allocations for

2011. This reclassification amounted to a decrease in pre-tax net investment income of approximately $78,000 or $0.012 per share ($49,000 or $0.008 per share, net of deferred tax benefit), an increase in unrealized appreciation of investments of approximately $47,000 or $0.007 per share ($30,000 or $0.005 per share, net of deferred tax expense), and an increase in realized gains of approximately $31,000 or $0.005 per share ($19,000 or $0.003 per share, net of deferred tax expense).

F. 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 (if any) following such distribution. The character of distributions to 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 distributions to common stockholders for the year ended November 30, 2011 and the period ended May 31, 2012 was 100 percent return of capital. For tax purposes, the Company’s distributions for the year ended November 30, 2011 were 100 percent qualified dividend income. The tax character of distributions paid to common stockholders in the current year will be determined subsequent to November 30, 2012.

G. Federal Income Taxation

From the Company’s inception through November 30, 2008, the Company qualified as a regulated investment company (“RIC”) under the U.S. Internal Revenue Code of 1986, as amended (the “Code”). Effective December 1, 2008, the Company is treated as a taxable corporation for federal and state income tax purposes. 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; however, the Company anticipates a marginal effective rate of 34 percent due to expectations of the level of taxable income relative to the federal graduated tax rates, including the tax rate anticipated when temporary differences reverse. 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 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.

H. 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. Debt issuance costs related to long-term debt obligations are capitalized and amortized over the period the debt is outstanding.

I. Derivative Financial Instruments

The Company uses derivative financial instruments (principally interest rate swap and forward foreign currency contracts) to manage interest rate and currency risks. 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. Cash settlements under the terms of the interest rate swap and forward foreign currency contracts and termination of such contracts are recorded as realized gains or losses in the accompanying Statement of Operations.

J. 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.

K. 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 evaluating the impact of these amendments, but currently does not believe they will have a material impact on the Company’s financial statements.

3. Concentration of Risk

Under normal conditions, the Company will have at least 80 percent of its total assets in equity securities of companies in the energy sector with their primary operations in North America (“Energy Companies”). Energy Companies include companies that derive more than 50 percent of their revenues from transporting, processing, storing, distributing or marketing natural gas, natural gas liquids, electricity, coal, crude oil or refined petroleum products, or exploring, developing, managing or producing such commodities. The Company may invest up to 50 percent of its total assets in restricted 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 1.00 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, if any) (“Managed Assets”), in exchange for the investment advisory services provided. The Adviser waived fees in an amount equal to an annual rate of 0.05 percent of the Company’s average monthly Managed Assets from January 1, 2011 through December 31, 2011.

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 plan.

U.S. Bank, N.A. serves as custodian of the Company’s cash and investment securities. 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 May 31, 2012, are as follows:

Deferred tax assets:
Net operating loss carryforwards		$	6,605,151
Capital loss carryforwards			4,967,605
Alternative minimum tax credit			30,000
Organization costs			44,326
State of Kansas credit			4,055
			11,651,137
Deferred tax liabilities:
Basis reduction of investment in MLPs			7,166,511
Net unrealized gains on investment securities			23,478,192
			30,644,703
Total net deferred tax liability		$	18,993,566

At May 31, 2012, 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 the Company’s estimates of future taxable income 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 May 31, 2012, the Company had no uncertain tax positions and no penalties and interest were accrued. Tax years subsequent to the year ending November 30, 2006 remain open to examination by federal and state tax authorities.

Total income tax benefit differs from the amount computed by applying the federal statutory income tax rate of 34 percent to net investment loss and net realized gains and unrealized losses on investments for the period ended May 31, 2012, as follows:

Application of statutory income tax rate		$	799,408
State income taxes, net of federal tax effect			75,003
Dividends received deduction			41,927
Total income tax benefit		$	916,338

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

For the period from December 1, 2011 through May 31, 2012, the components of income tax benefit include deferred federal and state income tax benefit (net of federal tax effect) of $837,738 and $78,600, respectively.

The Company acquired all of the net assets of Tortoise Gas and Oil Corporation (“TGO”) on September 14, 2009 in a tax-free reorganization under Section 368(a)(1)(C) of the Internal Revenue Code. As of November 30, 2011, the Company had a net operating loss for federal income tax purposes of approximately $10,989,000. This includes a net operating loss of $7,935,000 from TGO. The net operating loss may be carried forward for 20 years. If not utilized, this net operating loss will expire as follows: $2,677,000, $5,258,000, $807,000 and $2,247,000 in the years ending November 30, 2027, 2028, 2029 and 2030, respectively. Utilization of the net operating loss from TGO is further subject to Section 382 limitations of the Internal Revenue Code, which limit tax attributes subsequent to ownership changes.

As of November 30, 2011, the Company had a capital loss carryforward of approximately $15,000,000 which may be carried forward for 5 years. This amount includes a capital loss of $2,700,000 from TGO. If not utilized, the capital loss will expire as follows: $1,500,000, $5,500,000 and $8,000,000 in the years ending November 30, 2012, 2013 and 2014, respectively. The amount of deferred tax asset for these items at May 31, 2012 also includes amounts for the period from December 1, 2011 through May 31, 2012. For corporations, capital losses can only be used to offset capital gains and cannot be used to offset ordinary income. As of November 30, 2011, an alternative minimum tax credit of $30,000 was available, which may be credited in the future against regular income tax. This credit may be carried forward indefinitely.

As of May 31, 2012, the aggregate cost of securities for federal income tax purposes was $119,084,343. The aggregate gross unrealized appreciation for all securities in which there was an excess of fair value over tax cost was $84,543,235, the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over fair value was $1,046,051 and the net unrealized appreciation was $83,497,184.

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 May 31, 2012. These assets are measured on a recurring basis.

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.

Interest rate swap contracts are valued by using industry-accepted models which discount the estimated future cash flows based on a forward rate curve and the stated terms of the interest rate swap agreement by using interest rates currently available in the market, or based on dealer quotations, if available, which applies to the Company’s Level 2 liabilities.

The Company utilizes the beginning of reporting period method for determining transfers between levels. For the period from December 1, 2011 through May 31, 2012, Teekay Offshore Partners, L.P. common units in the amount of $1,371,505 were transferred from Level 2 to Level 1 when they converted into registered units and quoted prices in active markets were available. There were no other transfers between levels.

7. Investment Transactions

For the period from December 1, 2011 through May 31, 2012, the Company purchased (at cost) and sold securities (proceeds received) in the amount of $17,833,901 and $16,613,907 (excluding short-term debt securities), respectively.

8. Credit Facility

On June 15, 2011, the Company entered into a 270-day rolling evergreen margin loan facility with Bank of America, N.A. The terms of the agreement provide for a $40,000,000 facility that is secured by certain of the Company’s assets. Outstanding balances generally will accrue interest at a variable rate equal to one-month LIBOR plus 0.85 percent and unused portions of the facility will accrue a fee equal to an annual rate of 0.25 percent.

The average principal balance and interest rate for the period during which the margin loan facility was utilized during the period from December 1, 2011 through May 31, 2012 was approximately $31,900,000 and 1.11 percent, respectively. At May 31, 2012, the principal balance outstanding was $30,000,000 at an interest rate of 1.09 percent.

Under the terms of the margin loan 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 May 31, 2012, the Company was in compliance with the terms of the margin loan facility.

9. Interest Rate Swap Contracts

The Company has entered into interest rate swap contracts in an attempt to protect itself from increasing interest expense on its leverage resulting from increasing short-term interest rates. A decline in interest rates may result in a decline in the value of the swap contracts, which may result in a decline in the net assets of the Company. At the time the interest rate swap contracts reach their scheduled termination, there is a risk that the Company would not be able to obtain a replacement transaction, or that the terms of the replacement would not be as favorable as on the expiring transaction. In addition, if the Company is required to terminate any swap contract early due to the net assets of the Company falling below $48,000,000 or the Company failing to maintain a required 300 percent asset coverage of the liquidation value of the outstanding debt, then the Company could be required to make a termination payment to the extent of the Company’s net liability position, in addition to redeeming all or some of the debt. The Company has segregated a portion of its assets as collateral for the amount of the net liability of its interest rate swap contracts. Details of the interest rate swap contracts outstanding as of May 31, 2012, are as follows:

							Fixed Rate			Floating Rate
		Maturity		Notional			Paid by the			Received by		Liability
Counterparty		Date		Amount		Company		the Company		Derivatives
The Bank of Nova Scotia		09/02/2014		$	5,000,000		0.654	%		1-month U.S. Dollar LIBOR		$	(26,571	)
The Bank of Nova Scotia		09/02/2016			5,000,000		1.258	%		1-month U.S. Dollar LIBOR			(118,149	)
The Bank of Nova Scotia		09/02/2018			5,000,000		1.815	%		1-month U.S. Dollar LIBOR			(228,444	)
The Bank of Nova Scotia		09/02/2021			10,000,000		2.381	%		1-month U.S. Dollar LIBOR			(754,031	)
				$	25,000,000							$	(1,127,195	)

The Company is exposed to credit risk on the interest rate swap contracts if the counterparty should fail to perform under the terms of the interest rate swap contracts. The amount of credit risk is limited to the net appreciation of the interest rate swap contracts, if any, as no collateral is pledged by the counterparty. In addition, if the counterparty to the interest rate swap contracts defaults, the Company would incur a loss in the amount of the receivable and would not receive amounts due from the counterparty to offset the interest payments on the Company’s leverage.

The unrealized depreciation of interest rate swap contracts in the amount of $726,629 for the period ended May 31, 2012 is included in the Statement of Operations. Cash settlement payments under the terms of the interest rate swap contracts in the amount of $181,689 are recorded as realized losses for the period ended May 31, 2012. The total notional amount of all open swap agreements at May 31, 2012 is indicative of the volume of this derivative type for the period ended May 31, 2012.

10. Common Stock

The Company has 100,000,000 shares of capital stock authorized and 6,295,750 shares outstanding at May 31, 2012 and November 30, 2011.

11. Subsequent Events

On June 1, 2012, the Company paid a distribution in the amount of $0.3875 per common share, for a total of $2,439,603. Of this total, the dividend reinvestment amounted to $136,630.

The Company has performed an evaluation of subsequent events through the date the financial statements were issued and has determined that no additional items require recognition or disclosure.
