Investment commentary

Economic review

Economic activity in the U.S. was somewhat mixed during the six months ended May 31, 2018 (the “reporting period”). Looking back, the U.S. Department of Commerce reported that third and fourth quarter 2017 U.S. gross domestic product (“GDP”)ⁱ growth was 3.2% and 2.9%, respectively. Finally, the U.S. Department of Commerce’s final reading for first quarter 2018 GDP growth — released after the reporting period ended — was 2.0%. More modest GDP growth in the first quarter reflected decelerations in personal consumption expenditures (“PCE”), exports, state and local government spending, and federal government spending and a downturn in residential fixed investment. These movements were partly offset by a smaller decrease in private inventory investment and a larger increase in nonresidential fixed investment.

Job growth in the U.S. was solid overall and supported the economy during the reporting period. When the reporting period ended on May 31, 2018, the unemployment rate was 3.8%, as reported by the U.S. Department of Labor. This was the lowest unemployment rate since April 2000. The percentage of longer-term unemployed declined during the reporting period. In May 2018, 19.4% of Americans looking for a job had been out of work for more than six months, versus 22.9% when the period began.

Investment commentary (cont’d)

Market review

Q. How did the Federal Reserve Board (the “Fed”)ⁱⁱ respond to the economic environment?

A. The Fed increased the federal funds rateⁱⁱⁱ twice during the reporting period. Looking back, at its meeting that concluded on September 20, 2017 — before the reporting period began — the Fed kept rates on hold but reiterated its intention to begin reducing its balance sheet, saying, “In October, the Committee will initiate the balance sheet normalization program….” At its meeting that ended on December 13, 2017, the Fed raised rates to a range between 1.25% and 1.50%. As expected, the Fed kept rates on hold at its meeting that concluded on January 31, 2018. However, at its meeting that ended on March 21, 2018, the Fed again raised the federal funds rate, moving it to a range between 1.50% and 1.75%. Finally, at its meeting that concluded on June 13, 2018 — after the reporting period ended — the Fed raised the federal funds rate to a range between 1.75% and 2.00%.

Q. What factors impacted the U.S. stock market during the reporting period?

A. Despite times of weakness, the U.S. stock market posted positive results for the reporting period. The market moved higher during the first two months of the period and reached several new all-time highs. This was driven by overall solid corporate profits, signs of continued economic growth and, in December 2017, the signing of the U.S. tax reform bill. However, the market then gave back a portion of its gains in February and March 2018. This occurred given concerns that the Fed may raise interest rates more aggressively than previously expected. In addition, there were fears of a global trade war and several high profile issues in the technology industry. The market ended the reporting period on a positive note, as it rallied in April and May 2018. All told, for the six months ended May 31, 2018, the S&P 500 Index^iv gained 3.16%.

Looking at the U.S. stock market more closely, small-cap stocks, as measured by the Russell 2000 Index^v, generated the strongest results, returning 6.47% over the reporting period. In contrast, large-cap stocks, as measured by the Russell 1000 Index^vi, gained 3.33% and mid-cap stocks, as measured by the Russell Midcap Index^vii, returned 2.59%. From an investment style perspective, growth and value stocks, as measured by the Russell 3000 Growth^viii and Russell 3000 Value^ix Indices, returned 7.21% and -0.17%, respectively, during the six months ended May 31, 2018.

Looking at the energy master limited partnership (“MLP”) market, over the six-month reporting period ended May 31, 2018, the Alerian MLP Index^x returned 5.71%. Oil prices rose steadily throughout most of the reporting period, faltering temporarily in February 2018 in sympathy with the equity market as it corrected and as inventories rose, and again late in May 2018 in advance of June’s Organization of the Petroleum Exporting Countries (“OPEC”) meeting, which some investors feared would bring an easing of supply cuts. Broadly, prices were buoyed by strong global demand stemming from synchronized global growth, steady non-U.S. production cuts and elevated geopolitical risks to supply. A Federal Energy Regulatory Commission (“FERC”)^xi ruling in March 2018, changing how MLPs will be allowed to calculate allowed rates of return on some interstate pipelines, led to a temporary downdraft in MLPs. The MLP market regained all of these losses by the

end of May 2018, however, as investors began to understand that not all MLP companies were affected by the FERC ruling and valuations for the sector remained attractive.

Performance review

For the six months ended May 31, 2018, ClearBridge Energy MLP Total Return Fund Inc. returned 4.13% based on its net asset value (“NAV”)^xii and 9.24% based on its New York Stock Exchange (“NYSE”) market price per share. The Lipper Energy MLP Closed-End Funds Category Average^xiii returned 8.58% over the same time frame. Please note that Lipper performance returns are based on each fund’s NAV.

During this six-month period, the Fund made distributions to shareholders totaling $0.58 per share. As of May 31, 2018, the Fund estimates that all of the distributions constituted a return of capital.* The performance table shows the Fund’s six-month total return based on its NAV and market price as of May 31, 2018.

#	On December 22, 2017, the Fund adjusted its deferred tax liability balance to reflect updated assumptions regarding effective tax rates, resulting in a one-time increase to the NAV.

RISKS: The Fund is a non-diversified, closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objective. The Fund’s common stock is traded on the New York Stock Exchange. Similar to stocks, the Fund’s share price will fluctuate with market conditions and, at the time of sale, may be worth more or less than the original investment. Shares of closed-end funds often trade at a discount to their net asset value. Because the Fund is non-diversified, it may be more susceptible to economic, political or regulatory events than a diversified fund. The Fund’s investments are subject to a number of risks, including stock market risk, MLP risk, market events risk and portfolio management risk. MLP distributions are not guaranteed and there is no assurance that all distributions will be tax deferred. Investments in MLP securities are subject to unique risks. The Fund’s concentration of investments in energy related MLPs subject it to the risks of MLPs and the energy sector, including the risks of declines in energy and commodity prices, decreases in energy demand, adverse weather conditions, natural or other disasters, changes in government regulation, and changes in tax laws. Leverage may result in greater volatility of NAV and the market price of common shares and increases a shareholder’s risk of loss. The Fund may make significant investments in derivative instruments. Derivative instruments can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. The Fund may invest in small capitalization or illiquid securities which can increase the risk and volatility of the Fund.

All investments are subject to risk including the possible loss of principal. Past performance is no guarantee of future results. All index performance reflects no deduction for fees, expenses or taxes. Please note that an investor cannot invest directly in an index.

The information provided is not intended to be a forecast of future events, a guarantee of future results or investment advice. Views expressed may differ from those of the firm as a whole.

10		ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report

Notes to financial statements (unaudited)

1. Organization and significant accounting policies

ClearBridge Energy MLP Total Return Fund Inc. (the “Fund”) was incorporated in Maryland on April 10, 2012 and is registered as a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Board of Directors authorized 100 million shares of $0.001 par value common stock. The Fund’s investment objective is to provide a high level of total return, consisting of cash distributions and capital appreciation. The Fund seeks to achieve its objective by investing primarily in master limited partnerships (“MLPs”) in the energy sector. There can be no assurance that the Fund will achieve its investment objective.

Under normal market conditions, the Fund will invest at least 80% of its Managed Assets in MLPs in the energy sector (the “80% policy”). For purposes of the 80% policy, the Fund considers investments in MLPs to include investments that offer economic exposure to public and private MLPs in the form of equity securities of MLPs, securities of entities holding primarily general partner or managing member interests in MLPs, securities that are derivatives of interests in MLPs, including I-Shares, exchange-traded funds that primarily hold MLP interests and debt securities of MLPs. Energy entities are engaged in the business of exploring, developing, producing, gathering, transporting, processing, storing, refining, distributing, mining or marketing of natural gas, natural gas liquids (including propane), crude oil, refined petroleum products or coal. “Managed Assets” means net assets plus the amount of any borrowings and assets attributable to any preferred stock of the Fund that may be outstanding.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Investments in open-end funds are valued at the closing net asset value per share of each fund on the day of valuation. If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using


ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report		11

Notes to financial statements (unaudited) (cont’d)

quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Directors.

The Board of Directors is responsible for the valuation process and has delegated the supervision of the daily valuation process to the Legg Mason North Atlantic Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee, pursuant to the policies adopted by the Board of Directors, is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Board of Directors. When determining the reliability of third party pricing information for investments owned by the Fund, the Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer’s financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts’ research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Directors, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board of Directors quarterly.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.


12		ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. 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, interest rates, prepayment speeds, credit risk, etc.)

•

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

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets carried at fair value:


ASSETS
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Long-term investments†:
Master limited partnerships	$	562,651,992		—		—	$	562,651,992
Common stocks		89,322,469		—		—		89,322,469
Total long-term investments		651,974,461		—		—		651,974,461
Short-term investments†		18,054,650		—		—		18,054,650
Total investments	$	670,029,111		—		—	$	670,029,111

†	See Schedule of Investments for additional detailed categorizations.

(b) Net asset value. The Fund determines the net asset value of its common stock on each day the NYSE is open for business, as of the close of the customary trading session (normally 4:00 p.m. Eastern Time), or any earlier closing time that day. The Fund determines the net asset value per share of common stock by dividing the value of the Fund’s securities, cash and other assets (including interest accrued but not collected) less all its liabilities (including accrued expenses, borrowings, interest payables and the aggregate liquidation value (i.e., $100,000 per outstanding share) of the Mandatory Redeemable Preferred Stock), net of income taxes, by the total number of shares of common stock outstanding.

(c) Master limited partnerships. Entities commonly referred to as “MLPs” are generally organized under state law as limited partnerships or limited liability companies. The Fund intends to primarily invest in MLPs receiving partnership taxation treatment under the Internal Revenue Code of 1986, as amended (the “Code”), and whose interests or “units” are traded on securities exchanges like shares of corporate stock. To be treated as a partnership for U.S. federal income tax purposes, an MLP whose units are traded on a securities exchange must receive at least 90% of its income from qualifying sources such as interest,


ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report		13

Notes to financial statements (unaudited) (cont’d)

dividends, real estate rents, gain from the sale or disposition of real property, income and gain from mineral or natural resources activities, income and gain from the transportation or storage of certain fuels, and, in certain circumstances, income and gain from commodities or futures, forwards and options with respect to commodities. Mineral or natural resources activities include exploration, development, production, processing, mining, refining, marketing and transportation (including pipelines) of oil and gas, minerals, geothermal energy, fertilizer, timber or industrial source carbon dioxide. An MLP consists of a general partner and limited partners (or in the case of MLPs organized as limited liability companies, a managing member and members). The general partner or managing member typically controls the operations and management of the MLP and has an ownership stake in the partnership. The limited partners or members, through their ownership of limited partner or member interests, provide capital to the entity, are intended to have no role in the operation and management of the entity and receive cash distributions. The MLPs themselves generally do not pay U.S. federal income taxes. Thus, unlike investors in corporate securities, direct MLP investors are generally not subject to double taxation (i.e., corporate level tax and tax on corporate dividends). Currently, most MLPs operate in the energy and/or natural resources sector.

(d) Concentration risk. Concentration in the energy sector may present more risks than if the Fund were broadly diversified over numerous sectors of the economy. A downturn in the energy sector of the economy could have a larger impact on the Fund than on an investment company that does not concentrate in the sector. At times, the performance of securities of companies in the sector may lag the performance of other sectors or the broader market as a whole.

(e) Return of capital estimates. Distributions received from the Fund’s investments in MLPs generally are comprised of income and return of capital. The Fund records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded.

For the six months ended May 31, 2018, the Fund estimated that approximately 89% of the MLP distributions received would be treated as a return of capital. The Fund recorded as return of capital the amount of $23,237,909 of dividends and distributions received from its investments.

Additionally, the Fund recorded revisions to the return of capital estimates from the year ended November 30, 2017 in the amount of a $522,919 increase in dividends and distributions received from investments.

(f) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income (including interest income from payment-in-kind securities), adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date for


14		ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report

dividends received in cash and/or securities. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(g) Distributions to shareholders. Distributions to common shareholders are declared and paid on a quarterly basis and are recorded on the ex-dividend date. The estimated characterization of the distributions paid to common shareholders will be either a dividend (ordinary income) or distribution (return of capital). This estimate is based on the Fund’s operating results during the period. The Fund anticipates that 100% of its current period distribution to common shareholders will be treated as return of capital. The actual tax characterization of the common stock distributions made during the current period will not be determined until after the end of the fiscal year when the Fund can determine its earnings and profits and, therefore, may differ from the preliminary estimates.

Distributions to holders of Mandatory Redeemable Preferred Stock (“MRPS”) are accrued on a daily basis as described in Note 7 and are treated as an operating expense as required by GAAP. For tax purposes, the payments made to the holders of the Fund’s MRPS are treated as a dividend (ordinary income) or distribution (return of capital) similar to the treatment of distributions made to common shareholders as described above. The Fund anticipates that 100% of its current period distribution to the MRPS shareholders will be treated as return of capital. The actual tax characterization of the MRPS distributions made during the current period will not be determined until after the end of the fiscal year when the Fund can determine its earnings and profits and, therefore, may differ from the preliminary estimates.

(h) Compensating balance arrangements. The Fund has an arrangement with its custodian bank whereby a portion of the custodian’s fees is paid indirectly by credits earned on the Fund’s cash on deposit with the bank.

(i) Partnership accounting policy. The Fund records its pro rata share of the income (loss) and capital gains (losses), to the extent of distributions it has received, allocated from the underlying partnerships and accordingly adjusts the cost basis of the underlying partnerships for return of capital. These amounts are included in the Fund’s Statement of Operations.

(j) Federal and other taxes. The Fund, as a corporation, is obligated to pay federal and state income tax on its taxable income. The Fund 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 Fund includes its allocable share of the MLP’s taxable income in computing its own taxable income. The Fund, and entities in which the Fund invests, may be subject to audit by the Internal Revenue Service or other applicable tax authorities. The Fund’s taxable income or tax liability for prior taxable years could be adjusted if there is an audit of the


ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report		15

Notes to financial statements (unaudited) (cont’d)

Fund, or of any entity that is treated as a partnership for tax purposes in which the Fund holds an equity interest. The Fund may be required to pay tax, as well as interest and penalties, in connection with such an adjustment.

Deferred income taxes reflect (i) taxes on unrealized gains (losses), which are attributable to the temporary difference between fair market value and book basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and, as applicable, (iii) the net tax benefit of accumulated net operating losses, capital losses and tax credit carryforwards. To the extent the Fund has a deferred tax asset, consideration is given as to whether or not a valuation allowance is required. The need to establish a valuation allowance for deferred tax assets is assessed periodically by the Fund based on Financial Accounting Standards Board (“FASB”), Accounting Standards Codification Topic 740, Income Taxes (“ASC 740”) that it is more likely than not that some portion or all of the deferred tax asset will not be realized. In the assessment for a valuation allowance, consideration is given to all positive and negative evidence related to the realization of the deferred tax asset. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability (which are highly dependent on future allocations of taxable income and future cash distributions from the Fund’s MLP holdings), the duration of statutory carryforward periods and the associated risk that net operating losses, capital losses and tax credit carryforwards may expire unused.

For all open tax years and for all major jurisdictions, management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Furthermore, management of the Fund is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

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

The Fund’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. The 2013 through 2017 tax years remain open and subject to examination by tax jurisdictions.

(k) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. During the period ended May 31, 2018, the Fund had no reclassifications.

2. Investment management agreement and other transactions with affiliates

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) is the Fund’s investment manager and ClearBridge Investments, LLC (“ClearBridge”) is the Fund’s subadviser. LMPFA and ClearBridge are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”).

Under the investment management agreement, the Fund pays LMPFA an annual fee, paid monthly, in an amount equal to 1.00% of the Fund’s average daily Managed Assets.

LMPFA provides administrative and certain oversight services to the Fund. LMPFA delegates to the subadviser the day-to-day portfolio management of the Fund. For its services, LMPFA pays ClearBridge monthly 70% of the net management fee it receives from the Fund.

During periods in which the Fund utilizes financial leverage, the fees paid to LMPFA will be higher than if the Fund did not utilize leverage because the fees are calculated as a percentage of the Fund’s assets, including those investments purchased with leverage.

All officers and one Director of the Fund are employees of Legg Mason or its affiliates and do not receive compensation from the Fund.

3. Investments

During the six months ended May 31, 2018, the aggregate cost of purchases and proceeds from sales of investments (excluding short-term investments) were as follows:


Purchases	$	31,279,393
Sales		28,854,709

4. Derivative instruments and hedging activities

During the six months ended May 31, 2018, the Fund did not invest in derivative instruments.

5. Loan

Effective May 29, 2018, the Fund has a revolving credit agreement with The Bank of Nova Scotia (“Credit Agreement”), which allows the Fund to borrow up to an aggregate amount of $100,000,000 and renews daily for a 179-day term, unless notice to the contrary is given to the Fund. The Fund pays a commitment fee on the unutilized portion of the loan commitment amount at an annual rate of 0.25%, except that the commitment fee is 0.15% in the event that the aggregate outstanding principal balance of the loan is equal to or greater than 75% of $100,000,000. The interest on the loan is calculated at a variable rate based on LIBOR plus any applicable margin. Securities held by the Fund are subject to a lien, granted to The Bank of Nova Scotia, to the extent of the borrowing outstanding and any additional expenses. The Fund’s Credit Agreement contains customary covenants that, among other things, may limit the Fund’s ability to pay distributions in certain circumstances, incur additional debt, change its fundamental investment policies and engage in certain transactions, including mergers and consolidations and require asset coverage ratios in addition to those required by the 1940 Act. In addition, the Credit Agreement may be subject to early termination under certain conditions and may contain other provisions that could limit the Fund’s


ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report		17

Notes to financial statements (unaudited) (cont’d)

ability to utilize borrowing under the agreement. Interest expense related to this loan for the period ended May 31, 2018 was $12,007. For the period ended May 31, 2018, the Fund incurred commitment fees of $958. For the period ended May 31, 2018, based on the number of days during the reporting period that the Fund had an outstanding balance under the Credit Agreement, the Fund had an average daily loan balance outstanding of $54,000,000 and the weighted average interest rate was 2.71%. At May 31, 2018, the Fund had $54,000,000 of borrowings outstanding per this credit agreement.

Prior to May 29, 2018, the Fund had a 364-day revolving credit agreement with State Street Bank and Trust Company (“Prior Credit Agreement”), which allowed the Fund to borrow up to an aggregate amount of $100,000,000. The Prior Credit Agreement terminated on May 29, 2018. The Fund paid a commitment fee at an annual rate of 0.25% on the unutilized portion of the loan commitment amount. The interest on the loan was calculated at variable rates based on the LIBOR, plus any applicable margin. Securities held by the Fund were subject to a lien, granted to State Street Bank and Trust Company to the extent of the borrowing outstanding and any additional expenses. The Fund’s Prior Credit Agreement contained customary covenants that, among other things, may have limited the Fund’s ability to pay distributions in certain circumstances, incur additional debt, change its fundamental investment policies and engage in certain transactions, including mergers and consolidations, and require asset coverage ratios in addition to those required by the 1940 Act. In addition, the Prior Credit Agreement may have been subject to early termination under certain conditions and may have contained other provisions that could have limited the Fund’s ability to utilize borrowing under the agreement. Interest expense related to this loan for the period ended May 29, 2018 was $544,476. For the period ended May 29, 2018, the Fund incurred commitment fees of $70,930. For the period ended May 29, 2018, based on the number of days during the reporting period that the Fund had an outstanding balance under the Prior Credit Agreement, the Fund had an average daily loan balance outstanding of $42,592,179 and the weighted average interest rate was 2.61%.

6. Senior secured notes

At May 31, 2018, the Fund had $142,000,000 aggregate principal amount of fixed-rate senior secured notes (“Senior Notes”) outstanding. Interest expense related to the Senior Notes for the six months ended May 31, 2018 was $2,713,708. Costs incurred by the Fund in connection with the Senior Notes are recorded as a deferred charge, which are amortized over the life of the notes. Securities held by the Fund are subject to a lien, granted to the Senior Notes holders, to the extent of the borrowings outstanding and any additional expenses. The Senior Notes holders and the lender have equal access to the lien (See Note 5).

7. Mandatory redeemable preferred stock

At May 31, 2018, the Fund had 140 shares of fixed rate Mandatory Redeemable Preferred Stock (“MRPS”) outstanding with an aggregate liquidation value of $14,000,000. Offering costs incurred by the Fund in connection with the MRPS issuance are being amortized to expense over the respective life of each series of MRPS.

The table below summarizes the key terms of each series of the MRPS at May 31, 2018.


Series	Term Redemption Date		Rate			Shares		Liquidation Preference Per Share		Aggregate Liquidation Value		Estimated Fair Value

										$	14,000,000	$	13,799,776

The MRPS are not listed on any exchange or automated quotation system. The estimated fair value of the MRPS was calculated, for disclosure purposes, based on estimated market yields and credit spreads for comparable instruments with similar maturity, terms and structure. The MRPS are categorized as Level 3 within the fair value hierarchy.

Holders of MRPS are entitled to receive quarterly cumulative cash dividends payable on the first business day following each quarterly dividend date (February 15, May 15, August 15 and November 15). In the event of a rating downgrade of any series of the MRPS below “A” by Fitch Ratings Inc., the applicable dividend rate will increase, according to a predetermined schedule, by 0.5% to 4.0%.

The MRPS rank senior to the Fund’s outstanding common stock and on parity with any other preferred stock. The Fund may, at its option, redeem the MRPS, in whole or in part, at the


ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report		19

Notes to financial statements (unaudited) (cont’d)

liquidation preference amount plus all accumulated but unpaid dividends plus the makewhole amount equal to the discounted value of the remaining scheduled payments. If the Fund fails to maintain a total leverage (debt and preferred stock) asset coverage ratio of at least 225% or is in default of specified rating agency requirements, the MRPS are subject to mandatory redemption under certain provisions.

The Fund may not declare dividends or make other distributions on shares of its common stock unless the Fund has declared and paid full cumulative dividends on the MRPS, due on or prior to the date of the common stock dividend or distribution, and meets the MRPS asset coverage and rating agency requirements.

The holders of the MRPS have one vote per share and vote together with the holders of common stock of the Fund as a single class except on matters affecting only the holders of MRPS or the holders of common stock. Pursuant to the 1940 Act, holders of the MRPS have the right to elect two Directors of the Fund, voting separately as a class.

8. Stock repurchase program

On November 16, 2015, the Fund announced that the Fund’s Board of Directors (the “Board”) had authorized the Fund to repurchase in the open market up to approximately 10% of the Fund’s outstanding common stock when the Fund’s shares are trading at a discount to net asset value. The Board has directed management of the Fund to repurchase shares of common stock at such times and in such amounts as management reasonably believes may enhance stockholder value. The Fund is under no obligation to purchase shares at any specific discount levels or in any specific amounts. During the six months ended May 31, 2018, the Fund did not repurchase any shares.

9. Income taxes

On December 22, 2017, the U.S. government signed into law comprehensive tax reform legislation commonly known as the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The Tax Act makes broad and complex changes to the Code, including but not limited to, (1) reducing the U.S. federal corporate income tax rate from 35% to 21%; (2) repealing the corporate alternative minimum tax (“AMT”); (3) creating a new limitation on the deductibility of business interest expense; and (4) changing the rules related to usage of net operating loss carryforwards. These changes generally go into effect for tax years beginning after December 31, 2017.

The modifications to the Code also significantly impact the MLPs in which the Fund invests. The ramification of these changes on the Fund are, as of yet, unknown.

The U.S. Securities and Exchange Commission (“SEC”) also issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the income tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the enactment of the Tax Act for companies to complete the accounting under ASC 740. In accordance with SAB 118, in the financial statements that include the reporting period in which the Tax Act was enacted, a company must reflect the income tax effects of


20		ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report

those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If the company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. As a result of the reduction in the U.S. federal corporate income tax rate under the Tax Act, the Fund has revalued its net deferred tax liability. This decrease was reflected in the Fund’s net asset value reported on December 22, 2017. The Fund’s revaluation of its net deferred tax liability is based on analyses and interpretations of information currently available. Uncertainties remain regarding the impact of the Tax Act due to future regulatory and rulemaking processes, prospects of additional corrective or supplemental legislation, and potential trade or other litigation. As a result, the actual impact on the net deferred tax liability may vary from the amount initially recorded. The Fund has been and will continue to assess the impact of the Tax Act during the measurement period, which should be no longer than one year from the date of enactment. No material adjustment has been recorded to the provisional revaluing of net deferred tax liability subsequent to the enactment of the Tax Act.

The Fund’s current and deferred income tax provision for the respective categories on the Statement of Operations are as follows:


	Net Investment Loss		Net Realized Gain		Change in Net Unrealized Appreciation		Total
Current tax expense (benefit)	$	(979,297)		—		—	$	(979,297)
Deferred tax expense (benefit)		(10,550,753)	$	14,917,044	$	1,029,269		5,395,560
Total tax expense (benefit)	$	(11,530,050)	$	14,917,044	$	1,029,269	$	4,416,263

The Fund’s federal and state income tax provision consist of the following:


	Federal		State		Total
Current tax expense (benefit)	$	(979,297)		—	$	(979,297)
Deferred tax expense (benefit)		4,699,802	$	695,758		5,395,560
Total tax expense (benefit)	$	3,720,505	$	695,758	$	4,416,263

Total income taxes have been computed by applying the U.S. federal statutory income tax rate of 21% plus a blended net state income tax rate of 2.4%. The Fund applied this rate to net investment income (loss) and realized and unrealized gains (losses) on investments before income taxes in computing its total income tax expense (benefit).

During the period, the Fund’s combined federal and state income tax rate decreased from 37.0% to 23.4% due to the enactment of the Tax Act, which reduced the U.S. federal


ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report		21

Notes to financial statements (unaudited) (cont’d)

corporate income tax rate from 35% to 21%. This decrease resulted in the additional income tax benefit and corresponding decrease in the Fund’s effective tax rate outlined below.

The provision for income taxes differs from the amount derived from applying the statutory income tax rate to net investment income (loss) and realized and unrealized gains (losses) before income taxes as follows:


Provision at statutory rates	21.00	%	$	4,972,138
State taxes, net of federal tax benefit	2.40	%		568,244
Non-deductible distributions on MRPS	0.31	%		72,477
Dividends received deduction	(0.65)	%		(155,036)
Change in valuation allowance	(4.65)	%		(1,101,949)
Change in U.S. federal tax rate	(0.09)	%		(22,359)
Other, net	0.33	%		82,748
Total tax expense (benefit)	18.65	%	$	4,416,263

Components of the Fund's net deferred tax asset (liability) as of May 31, 2018 are as follows:


Deferred tax assets
Net operating loss carryforward	$	14,697,368
Capital loss carryforward		23,305,806
Other deferred tax assets		229,406

Deferred tax liabilities
Unrealized gains on investment securities		(10,320,594)
Basis reduction resulting from differences in the book vs. taxable income received from MLPs		(33,307,546)
Total net deferred tax asset (liability)	$	(5,395,560)

At May 31, 2018, the Fund had federal and state net operating loss carryforwards of $62,413,207 and $28,651,675 (net of state apportionment), respectively (deferred tax asset of $14,697,368). Several states compute net operating losses before apportionment, therefore the value of the state net operating loss carryforward disclosed may fluctuate for changes in apportionment factors. Realization of the deferred tax asset related to the net operating loss carryforwards is dependent, in part, on generating sufficient taxable income in each respective jurisdiction prior to expiration of the loss carryforwards. If not utilized, the federal net operating loss carryforward expires in tax years 2034, 2036, and 2037, and the state net operating loss carryforwards expire in tax years between 2020 and 2037.

Additionally, at May 31, 2018, the Fund had a capital loss carryforward of $99,597,460 (deferred tax asset of $23,305,806), which may be carried forward for 5 years. During the period ended May 31, 2018, the Fund utilized $6,237,029 of capital loss carryforward available from previous years. If not utilized, this capital loss will expire in tax year 2020. For corporations, capital losses can only be used to offset capital gains and cannot be used to offset ordinary income. Therefore, the use of this capital loss carryforward is dependent upon the Fund generating sufficient net capital gains prior to the expiration of the loss carryforward.


22		ClearBridge Energy MLP Total Return Fund Inc. 2018 Semi-Annual Report

At May 31, 2018, the Fund also had a minimum tax credit carryforward of $979,297, which is available to offset against future regular federal tax liabilities. The minimum tax credit does not carry an expiration. The Tax Act repealed corporate AMT for tax years beginning after December 31, 2017 and provides that existing minimum tax credit carryforwards be refundable, subject to certain annual limitations, over the next four taxable years. As such, the Fund has moved this carryforward to an income tax receivable on the Statement of Assets and Liabilities.

The amount of net operating loss and capital loss carryforwards differed from the amounts disclosed in the prior year financial statements due to differences between the estimated and actual amounts of taxable income received from the MLPs for the prior year.

Although the Fund currently has a net deferred tax liability, it periodically reviews the recoverability of its deferred tax assets based on the weight of available evidence. When assessing the recoverability of its deferred tax assets, significant weight is given to the effects of potential future realized and unrealized gains on investments and the period over which these deferred tax assets can be realized. Based on the Fund’s assessment, it has determined that it is more likely than not that its deferred tax assets will be realized through future taxable income of the appropriate character. Accordingly, no valuation allowance has been established on the Fund’s deferred tax assets. The Fund will continue to assess the need for a valuation allowance in the future. Significant declines in the fair value of its portfolio of investments may change the Fund’s assessment regarding the recoverability of its deferred tax assets and may result in a valuation allowance. If a valuation allowance is required to reduce any deferred tax asset in the future, it could have a material impact on the Fund’s net asset value and results of operations in the period it is recorded.

At May 31, 2018, the cost basis of investments for Federal income tax purposes was $484,874,085. At May 31, 2018, gross unrealized appreciation and depreciation of investments for Federal income tax purposes were as follows:


Gross unrealized appreciation	$	226,644,148
Gross unrealized (depreciation)		(41,489,122)
Net unrealized appreciation (depreciation) before tax	$	185,155,026
Net unrealized appreciation (depreciation) after tax	$	141,828,750

Dividend reinvestment plan (unaudited)

On December 15, 2016, the Fund announced that the Board of Directors has authorized changes to the Fund’s Dividend Reinvestment Plan (the “Plan”) with respect to dividend reinvestment determinations and transaction fees for Plan participants selling their shares. A copy of the revised Plan is included below.

Effective July 1, 2017, the Fund uses the dividend payment date to determine if new shares are issued or shares are purchased in the open market for Plan participants reinvesting their distributions. If on the payment date the closing market price (plus $0.03 per share commission) is at or above the net asset value (“NAV”), the Fund will issue new shares of common stock. Newly issued shares of common stock will be issued at a price equal to the greater of (a) the NAV per share on the date prior to issuance or (b) 95% of the closing market price per share. If the closing market price (plus $0.03 per share commission) is lower than the NAV per share on the payment date, the Plan Agent will receive the distribution in cash and purchase common stock in the open market. In addition, effective July 1, 2017, fees paid by Plan participants to sell Fund shares decreased, with Plan participants paying a $5.00 transaction fee plus a $0.05 per share commission upon a sale of shares held pursuant to the Plan.

Revised dividend reinvestment plan:

Unless you elect to receive distributions in cash (i.e., opt-out), all dividends, including any capital gain dividends and return of capital distributions, on your Common Stock will be automatically reinvested by Computershare Trust Company, N.A., as agent for the stockholders (the “Plan Agent”), in additional shares of Common Stock under the Fund’s Dividend Reinvestment Plan (the “Plan”). You may elect not to participate in the Plan by contacting the Plan Agent. If you do not participate, you will receive all cash distributions paid by check mailed directly to you by Computershare Trust Company, N.A., as dividend paying agent.

If you participate in the Plan, the number of shares of Common Stock you will receive will be determined as follows:

(1) If the market price of the Common Stock (plus $0.03 per share commission) on the payment date (or, if the payment date is not a NYSE trading day, the immediately preceding trading day) is equal to or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date, the Fund will issue new Common Stock at a price equal to the greater of (a) the net asset value per share at the close of trading on the NYSE on the payment date or (b) 95% of the market price per share of the Common Stock on the payment date.

(2) If the net asset value per share of the Common Stock exceeds the market price of the Common Stock (plus $0.03 per share commission) at the close of trading on the NYSE on the payment date, the Plan Agent will receive the dividend or distribution in cash and will buy Common Stock in the open market, on the NYSE or elsewhere, for your account as soon as practicable commencing on the trading day following the payment date and terminating no later than the earlier of (a) 30 days after the dividend or distribution payment date, or (b) the payment date for the next succeeding


ClearBridge Energy MLP Total Return Fund Inc.		25

Dividend reinvestment plan (unaudited) (cont’d)

dividend or distribution to be made to the stockholders; except when necessary to comply with applicable provisions of the federal securities laws. If during this period: (i) the market price (plus $0.03 per share commission) rises so that it equals or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date before the Plan Agent has completed the open market purchases or (ii) if the Plan Agent is unable to invest the full amount eligible to be reinvested in open market purchases, the Plan Agent will cease purchasing Common Stock in the open market and the Fund shall issue the remaining Common Stock at a price per share equal to the greater of (a) the net asset value per share at the close of trading on the NYSE on the day prior to the issuance of shares for reinvestment or (b) 95% of the then current market price per share.

Common Stock in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all shares of Common Stock you have received under the Plan. You may withdraw from the Plan (i.e., opt-out) by notifying the Plan Agent in writing at 462 South 4th Street, Suite 1600, Louisville, KY 40202 or by calling the Plan Agent at 1-888-888-0151. Such withdrawal will be effective immediately if notice is received by the Plan Agent not less than ten business days prior to any dividend or distribution record date; otherwise such withdrawal will be effective as soon as practicable after the Plan Agent’s investment of the most recently declared dividend or distribution on the Common Stock.

Plan participants who sell their shares will be charged a service charge (currently $5.00 per transaction) and the Plan Agent is authorized to deduct brokerage charges actually incurred from the proceeds (currently $0.05 per share commission). There is no service charge for reinvestment of your dividends or distributions in Common Stock. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases. Because all dividends and distributions will be automatically reinvested in additional shares of Common Stock, this allows you to add to your investment through dollar cost averaging, which may lower the average cost of your Common Stock over time. Dollar cost averaging is a technique for lowering the average cost per share over time if the Fund’s net asset value declines. While dollar cost averaging has definite advantages, it cannot assure profit or protect against loss in declining markets.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions. Investors will be subject to income tax on amounts reinvested under the Plan.

The Fund reserves the right to amend or terminate the Plan if, in the judgment of the Board of Directors, the change is warranted. The Plan may be terminated, amended or supplemented by the Fund upon notice in writing mailed to stockholders at least 30 days prior to the record date for the payment of any dividend or distribution by the Fund for which the termination or amendment is to be effective. Upon any termination, you will be sent cash for any fractional share of Common Stock in your account. You may elect to notify the Plan Agent in advance of such termination to have the Plan Agent sell part or all of your Common

Stock on your behalf. Additional information about the Plan and your account may be obtained from the Plan Agent at 462 South 4th Street, Suite 1600, Louisville, KY 40202 or by calling the Plan Agent at 1-888-888-0151.
