EXPLANATION OF FINANCIAL STATEMENTS

As a shareholder in the fund, you receive shareholder reports semiannually. We strive to present this financial information in an easy-to-understand format; however, for many investors, the information contained in this shareholder report may seem very technical. So, we would like to take this opportunity to explain several sections of the shareholder report.

The Schedule of Investments details all of the securities held in the fund and their related dollar values on the last day of the reporting period. Securities are usually presented by type (bonds, common stock, etc.) and by industry classification (healthcare, education, etc.). This information is useful for analyzing how your fund’s assets are invested and seeing where your portfolio manager believes the best opportunities exist to meet your objectives. Holdings are subject to change without notice and do not constitute a recommendation of any individual security. The Notes to Financial Statements provide additional details on how the securities are valued.

The Statement of Assets and Liabilities lists the assets and liabilities of the fund on the last day of the reporting period and presents the fund’s net asset value (“NAV”) and market price per share. The NAV is calculated by dividing the fund’s net assets (assets minus liabilities) by the number of shares outstanding. The market price is the closing price on the exchange on which the fund’s shares trade. This price, which may be higher or lower than the fund’s NAV, is the price an investor pays or receives when shares of the fund are purchased or sold. The investments, as presented in the Schedule of Investments, comprise substantially all of the fund’s assets. Other assets include cash and receivables for items such as income earned by the fund but not yet received. Liabilities include payables for items such as fund expenses incurred but not yet paid.

The Statement of Operations details the dividends and interest income earned from investments as well as the expenses incurred by the fund during the reporting period. Fund expenses may be reduced through fee waivers or reimbursements. This statement reflects total expenses before any waivers or reimbursements, the amount of waivers and reimbursements (if any), and the net expenses. This statement also shows the net realized and unrealized gains and losses from investments owned during the period. The Notes to Financial Statements provide additional details on investment income and expenses of the fund.

The Statement of Changes in Net Assets describes how the fund’s net assets were affected by its operating results and distributions to shareholders during the reporting period. This statement is important to investors because it shows exactly what caused the fund’s net asset size to change during the period.

The Statement of Cash Flows is required when a fund has a substantial amount of illiquid investments, a substantial amount of the fund’s securities are internally fair valued, or the fund carries some amount of debt. When presented, this statement explains the change in cash during the reporting period. It reconciles net cash provided by and used for operating activities to the net increase or decrease in net assets from operations and classifies cash receipts and payments as resulting from operating, investing, and financing activities.

The Financial Highlights provide a per-share breakdown of the components that affected the fund’s NAV for the current and past reporting periods. It also shows total return, net investment income ratios, expense ratios, and portfolio turnover rates. The net investment income ratios summarize the income earned less expenses, divided by the average net assets. The expense ratios represent the percentage of average net assets that were used to cover operating expenses during the period. The portfolio turnover rate represents the percentage of the fund’s holdings that have changed over the course of the period, and gives an idea of how long the fund holds onto a particular security. A 100% turnover rate implies that an amount equal to the value of the entire portfolio is turned over in a year through the purchase or sale of securities.

The Notes to Financial Statements disclose the organizational background of the fund, its significant accounting policies, federal tax information, fees and compensation paid to affiliates, and significant risks and contingencies.

We hope this guide to your shareholder report will help you get the most out of this important resource.

Notes to Financial Statements      

(1) Organization

American Income Fund, Inc. (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”), as a diversified, closed-end management investment company. The fund invests in fixed-income securities, primarily in mortgage-backed securities. The fund also invests in other debt securities, such as collateralized mortgage obligations (CMOs) and asset-backed securities, high-yield bonds, corporate bonds, and preferred stock. The fund will invest at least 65% of its total assets in investment-grade securities under normal market conditions. No more than 35% of the fund’s total assets may be held in high-yield issues. The fund is authorized to borrow funds or issue senior securities in amounts not exceeding 33 1/3% of its total assets. Fund shares are listed on the New York Stock Exchange (“NYSE”) under the symbol MRF.

(2) Summary of
Significant
Accounting
Policies

Security Valuations

Security valuations for the fund’s investments are generally furnished by an independent pricing service that has been approved by the fund’s board of directors. Investments in equity securities that are traded on a national securities exchange (or reported on the Nasdaq national market system) are stated at the last quoted sales price if readily available for such securities on each business day. For securities traded on the Nasdaq national market system, the fund utilizes the Nasdaq Official Closing Price which compares the last trade to the bid/ask price of a security. If the last trade falls within the bid/ask range, then that price will be the closing price. If the last trade is outside the bid/ask range, and falls above the ask, the ask price will be the closing price. If the last trade is below the bid, the bid will be the closing price. Other equity securities traded in the over-the-counter market and listed equity securities for which no sale was reported on that date are stated at the last quoted bid price.

Debt obligations exceeding 60 days to maturity are valued by an independent pricing service. Securities for which prices are not available from an independent pricing service, but where an active market exists, are valued using market quotations obtained from one or more dealers that make markets in the securities or from a widely-used quotation system. Debt obligations with 60 days or less remaining until maturity may be valued at their amortized cost which approximates market value.

The following investment vehicles, when held by the fund, are priced as follows: exchange listed futures and options on futures are priced at their last sale price on the exchange on which they are principally traded, as determined by the fund’s investment advisor, U.S. Bancorp Asset Management, Inc. (“USBAM”), on the day the valuation is made. If there were no sales on that day, futures and options on futures will be valued at the last reported bid price. Options on securities, indices, and currencies traded on Nasdaq or listed on a stock exchange, whether domestic or foreign, are valued at the last sale price on Nasdaq or on any exchange on the day the valuation is made. If there were no sales on that day, the options will be valued at the last sale price on the previous valuation date. Last sale prices are obtained from an independent pricing service. Swaps and over-the-counter options on securities, indices, and currencies are valued at the quotations received from an independent pricing service, if available.

When market quotations are not readily available, securities are valued at fair value as determined in good faith by procedures established and approved by the fund’s board of directors. As of February 28, 2013, the fund held no internally fair valued securities.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

GAAP requires disclosures regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. the exit price). GAAP establishes a three-tier fair value hierarchy for observable and unobservable inputs used in measuring fair value. Observable inputs reflect the assumptions market participants

Notes to Financial Statements

would use in pricing an asset or liability and are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. Fair value inputs are summarized in the three broad levels listed below:

Level 1 - Quoted prices in active markets for identical securities.

Level 2 - Other significant observable inputs (including quoted prices for similar securities, with similar 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). Generally, the types of securities included in Level 3 of the fund are securities for which there are limited or no observable fair value inputs available, and as such the fair value is determined through independent broker quotations or management’s fair value procedures established by the fund’s board of directors.

The fair value levels are not necessarily an indication of the risk associated with investing in these investments.

As of February 28, 2013, the fund’s investments were classified as follows:

Valuation Methodologies for Fair Value Measurements Categorized within Levels 2 and 3

Debt obligations

High Yield Corporate Bonds, U.S. Government Agency Mortgage-Backed Securities, Collateralized Mortgage Obligation — Private Mortgage-Backed Securities, Collateralized Mortgage Obligation — U.S. Agency Mortgage-Backed Securities, Commercial Mortgage-Backed Securities, Asset-Backed Securities, and Investment Grade Corporate Bonds are valued by an independent pricing service. The pricing service may employ methodologies that utilize actual market transactions, broker-dealer supplied valuations, or other formula-driven valuation techniques. These techniques generally consider such factors as yields or prices of bonds of comparable quality, type of issue, coupon, maturity, ratings, and general market conditions. When the price provided by a pricing service is based on a sole broker quote, the value is categorized as Level 3 by the fund.

Preferred Stocks

When the price provided by a pricing service for a preferred stock is based on a sole broker quote, the value is categorized as Level 3 by the fund.

Notes to Financial Statements

Valuation Process for Fair Value Measurements Categorized within Level 3

The fund’s board of directors (the “board”) has adopted policies and procedures for the valuation of the fund’s investments (the “valuation procedures”). The valuation procedures established a valuation committee consisting of representatives from USBAM investment management, legal, treasury and compliance departments (the “valuation committee”). The board has authorized the valuation committee to make fair value determinations in accordance with the valuation procedures. The audit committee of the board meets on a regular basis to, among other things, review fair value determinations made by the valuation committee, monitor the appropriateness of any previously determined fair value methodology, and approve in advance any proposed changes to such methodology, and presents such changes for ratification by the board.

Security Transactions and Investment Income

For financial statement purposes, the fund records security transactions on the trade date of the security purchase or sale. Dividend income is recorded on the ex-dividend date. Interest income, including accretion of bond discounts and amortization of bond premiums, is recorded on an accrual basis. Security gains and losses are determined on the basis of identified cost, which is the same basis used for federal income tax purposes. The resulting gain/loss is calculated as the difference between the sales price and the underlying cost of the security on the transaction date.

Distributions to Shareholders

Distributions from net investment income are declared and paid on a monthly basis. Any net realized capital gains on sales of securities for the fund are distributed to shareholders at least annually. Such distributions are payable in cash or, pursuant to the fund’s dividend reinvestment plan, reinvested in additional shares of the fund’s capital stock. Under the plan, fund shares will be purchased in the open market unless the market price plus commissions exceeds the net asset value by 5% or more. If, at the close of business on the dividend payment date, the shares purchased in the open market are insufficient to satisfy the dividend reinvestment requirement, the fund may issue new shares at a discount of up to 5% from the current market price.

Federal Taxes

The fund intends to continue to qualify as a regulated investment company (“RIC”) as provided in Subchapter M of the Internal Revenue Code, as amended, and to distribute all taxable income, if any, to its shareholders. Accordingly, no provision for federal income taxes is required.

As of February 28, 2013, the fund did not have any tax positions that did not meet the “more-likely-than-not” threshold of being sustained by the applicable taxing authority. Generally, tax authorities can examine all the tax returns filed for the last three years.

Net investment income and net realized gains and losses may differ for financial statement and tax purposes because of temporary or permanent book/tax differences. These differences are primarily due to post-October losses, expiration of capital loss carry forwards, paydown gains and losses, and the tax recognition of mark-to-market gains and losses on open futures contracts. To the extent these differences are permanent, reclassifications are made to the appropriate capital accounts in the fiscal period that the differences arise.

The character of distributions made during the fiscal period from net investment income or net realized gains may differ from its ultimate characterization for federal income tax purposes. In addition, due to the timing of dividend distributions, the fiscal period in which amounts are distributed may differ from the fiscal period that the income or realized gains or losses were recorded by the fund.

20 AMERICAN INCOME FUND         2013 SEMIANNUAL REPORT

Under the Regulated Investment Company Modernization Act of 2010, the funds are permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. Any losses incurred during those taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under the previous law.

For federal income tax purposes, the fund had capital loss carryovers at August 31, 2012, the fund’s most recently completed fiscal year-end, which, if not offset by subsequent capital gains, will expire on the fund’s fiscal year-ends as follows:

Capital Loss Carryover		Expiration
$	1,449,151		2017
	632,033		Indefinite
$	2,081,184

The fund incurred losses of $682,391 for the period from November 1, 2011 to August 31, 2012. As permitted by tax regulations, the fund intends to elect to defer and treat those losses as arising in the fiscal year ended August 31, 2013.

Derivatives

The fund may invest in derivative financial instruments in order to manage risk or gain exposure to various other investments or markets. The fund’s investment objective allows the fund to enter into various types of derivative contracts, including, but not limited to, futures contracts, foreign exchange contracts, credit default swaps, interest rate swaps, total return swaps, currency swaps, and purchased and written options. Derivatives may contain various risks including the potential inability of the counterparty to fulfill their obligations under the terms of the contract, the potential for an illiquid secondary market, and the potential for market movements that may expose the fund to gains or losses in excess of the amounts shown on the Statement of Assets and Liabilities.

Futures Transactions

In order to protect against changes in interest rates, the fund may buy and sell interest rate futures contracts. Upon entering into a futures contract, the fund is required to deposit cash or pledge U.S. Government securities. Subsequent payments, which are dependent on the daily fluctuations in the value of the underlying security or securities, are made or received by the fund each day (daily variation margin) and recorded as unrealized gains (losses) until the contract is closed. When the contract is closed, the fund records a realized gain (loss) equal to the difference between the proceeds from (or cost of) the closing transaction and the fund’s basis in the contract.

AMERICAN INCOME FUND         2013 SEMIANNUAL REPORT 21

Notes to Financial Statements

Risks of entering into futures contracts, in general, include the possibility that there will not be a perfect price correlation between the futures contracts and the underlying securities. Second, it is possible that a lack of liquidity for futures contracts could exist in the secondary market, resulting in an inability to close a futures position prior to its maturity date. Third, the purchase of a futures contract involves the risk that the fund could lose more than the original margin deposit required to initiate a futures transaction. These contracts involve market risk in excess of the amount reflected in the fund’s Statement of Assets and Liabilities. Unrealized gains (losses) on outstanding positions in futures contracts held at the close of the period will be recognized as capital gains (losses) for federal income tax purposes. As of February 28, 2013, the fund had outstanding futures contracts as disclosed in the Schedule of Investments.

Swap Agreements

The fund may invest in swap agreements. A swap is an agreement to exchange the return generated by one instrument for the return generated by another instrument. The fund may enter into credit default, interest rate, and total return swap agreements to manage exposure to credit and interest rate risk. In connection with these agreements, securities may be identified as collateral in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

Swap agreements are marked-to-market daily based upon quotations from market makers and the change in value, if any, is recorded as unrealized gain or loss in the Statement of Operations. Payments received or made at the beginning of the measurement period are reflected on the Statement of Assets and Liabilities. A liquidation payment received or made at the termination of the swap agreement is recorded as realized gain or loss in the Statements of Operations. Net periodic payments received by the fund is included as part of interest from unaffiliated investments on the Statements of Operations. Entering into these agreements involves, to varying degrees, elements of credit, market and documentation risk in excess of the amounts recognized on the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements, and that there may be unfavorable changes in interest rates.

Credit Default Swaps

The fund is subject to credit risk in the normal course of pursuing its investment objective. The fund may enter into credit default swaps to manage its exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults of corporate and sovereign issuers, or to create exposure to corporate or sovereign issuers to which it is not otherwise exposed. Credit default swap agreements involve one party making a stream of payments (referred to as the buyer of protection) to another party (the seller of protection) in exchange for the right to receive a specified return in the event of a default or other credit event for the reference entity or index. As a seller of protection on credit default swap agreements, the fund will generally receive from the buyer of protection a fixed rate of income throughout the term of the swap provided that there is no credit event. As the seller, the fund would effectively add leverage to its portfolio because, in addition to its total net assets, the fund would be subject to investment exposure on the notional amount of the swap.

If a fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the reference entity, other deliverable obligations or underlying securities comprising the reference index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the reference entity or underlying securities comprising the reference index. If the fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the reference entity, other deliverable obligations or underlying securities comprising the reference index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the reference entity or underlying securities comprising the

22 AMERICAN INCOME FUND         2013 SEMIANNUAL REPORT

reference index. Recovery values are assumed by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value.

Implied credit spreads, represented in absolute terms, utilized in determining the value of credit default swap agreements on corporate issues or sovereign issues of an emerging country as of period end are disclosed in the footnotes to the Schedules of Investments and serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular reference entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. For credit default swap agreements on asset-backed securities and credit indices, the quoted market prices and resulting values serve as the indicator of the current status of the payment/performance risk. Wider credit spreads and increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

The maximum potential amount of future payments (undiscounted) that the fund as a seller of protection could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement. As of February 28, 2013, the fund had no outstanding credit default swap agreements.

Interest Rate Swaps

The fund is subject to interest rate risk exposure in the normal course of pursuing its investment objective. Because the fund holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the fund may enter into interest rate swap contracts. Interest rate swap agreements involve the exchange by the fund with another party of their respective commitments to pay or receive interest with respect to the notional amount of principal. Certain forms of interest rate swap agreements may include: (i) interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”, (ii) interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or “floor”, (iii) interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels, (iv) callable interest rate swaps, under which the counterparty may terminate the swap transaction in whole at zero cost by a predetermined date and time prior to the maturity date, (v) spreadlocks, which allow the interest rate swap users to lock in the forward differential (or spread) between the interest rate swap rate and a specified benchmark, or (vi) basis swap, under which two parties can exchange variable interest rates based on different money markets. The fund’s maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from/paid to the counterparty over the contract’s remaining life, to the extent that the amount is positive. This risk is mitigated by having a master netting arrangement between the fund and the counterparty and by the posting of collateral by the counterparty to the fund to cover the fund’s exposure to the counterparty. As of February 28, 2013, the fund had no outstanding interest rate swap agreements.

Total Return Swaps

Total return swap agreements on indices involve commitments to pay interest in exchange for a market-linked return. One counterparty pays out the total return of a specific reference asset, which may be an equity, index, or bond, and in return receives a regular stream of payments. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the fund will receive a payment from or make a payment to the counterparty. As of February 28, 2013, the fund had no outstanding total return swap agreements.

AMERICAN INCOME FUND         2013 SEMIANNUAL REPORT 23

Notes to Financial Statements

Options Transactions

The fund may utilize options in an attempt to manage market or business risk or enhance its yield. When a call or put option is written, an amount equal to the premium received is recorded as a liability. The liability is marked-to-market daily to reflect the current value of the option written. When a written option expires, a gain is realized in the amount of the premium originally received. If a closing purchase contract is entered into, a gain or loss is realized in the amount of the original premium less the cost of the closing transaction. If a written call is exercised, a gain or loss is realized from the sale of the underlying security, and the proceeds from such sale are increased by the premium originally received. If a written put option is exercised, the amount of the premium originally received reduces the cost of the security that is purchased upon exercise of the option.

Purchased options are recorded as investments and marked-to-market daily to reflect the current value of the option contract. If a purchased option expires, a loss is realized in the amount of the cost of the option. If a closing transaction is entered into, a gain or loss is realized to the extent that the proceeds from the sale are greater or less than the cost of the option. If a put option is exercised, a gain or loss is realized from the sale of the underlying security by adjusting the proceeds from such sale by the amount of the premium originally paid. If a call option is exercised, the cost of the security purchased upon exercise is increased by the premium originally paid. As of February 28, 2013, the fund had no written or purchased options outstanding.

Derivatives Support

For the six-month period ended February 28, 2013, the quarterly average gross notional amounts of the derivatives held by the fund were $20,406,347 for futures held short.

As of February 28, 2013, the fund’s asset and liability values of derivative instruments categorized by risk exposure were classified as follows:

Liability Derivatives	Statement of Assets and Liabilities Location	Value
Interest Rate Contracts	Payables, Net Assets-Unrealized Depreciation*	$	(40,930	)
Balance as of February 28, 2013		$	(40,930	)

* Includes cumulative appreciation (depreciation) of futures contracts as reported in the footnotes to the fund’s Schedule of Investments. Only the current day’s variation margin is reported within the Statement of Assets and Liabilities.

The effect of derivative instruments on the Statement of Operations for the six-month period ended February 28, 2013:

Amount of realized gain (loss) on derivatives recognized in income:

	Futures
Interest Rate Contracts	$	26,534

Change in unrealized appreciation (depreciation) on derivatives recognized in income:

	Futures
Interest Rate Contracts	$	53,929

Securities Purchased on a When-Issued Basis

Delivery and payment for securities that have been purchased by the fund on a when-issued or forward-commitment basis can take place up to a month or more after the transaction date. Such securities do not earn interest, are subject to market fluctuation, and may increase or decrease in value prior to their delivery. The fund segregates assets with a market value equal to or greater than the amount of its purchase commitments. The purchase of securities on a when-issued or forward-commitment basis may increase the volatility of the fund’s net asset value if the fund makes such purchases while remaining substantially fully invested. As of February 28, 2013, the fund had when-issued or forward-commitment securities outstanding with a total cost of $24,597,355.

24 AMERICAN INCOME FUND         2013 SEMIANNUAL REPORT

In connection with the ability to purchase securities on a when-issued basis, the fund may also enter into dollar rolls in which the fund sells securities purchased on a forward-commitment basis and simultaneously contracts with a counterparty to repurchase similar (same type, coupon, and maturity), but not identical securities on a specified future date. As an inducement for the fund to “rollover” its purchase commitments, the fund receives negotiated amounts in the form of reductions of the purchase price of the commitment. Dollar rolls are considered a form of leverage. As of and for the six-month period ended February 28, 2013, the fund had no dollar roll transactions.

Illiquid or Restricted Securities

A security may be considered illiquid if it lacks a readily available market. Securities are generally considered liquid if they can be sold or disposed of in the ordinary course of business within seven days at approximately the value at which the security is valued by the fund. Illiquid securities may be valued under methods approved by the fund’s board of directors as reflecting fair value. The fund intends to invest no more than 25% of its net assets (determined at the time of purchase and reviewed periodically) in illiquid securities. Certain restricted securities may be considered illiquid. Restricted securities are often purchased in private placement transactions, are not registered under the Securities Act of 1933, may have contractual restrictions on resale, and may be valued under methods approved by the fund’s board of directors as reflecting fair value. Certain restricted securities eligible for resale to qualified institutional investors, including rule 144A securities, are not subject to the limitation on a fund’s investment in illiquid securities if they are determined to be liquid in accordance with procedures adopted by the fund’s board of directors. As of February 28, 2013, the fund held 21 illiquid securities, the value of which was $8,214,149, which represents 10.0% of total net assets.

Information concerning illiquid securities, including restricted securities considered to be illiquid, is as follows:

Notes to Financial Statements

Reverse Repurchase Agreements

Reverse repurchase agreements involve the sale of a portfolio-eligible security by the fund coupled with an agreement to repurchase the security at a specified date and price. Reverse repurchase agreements may increase volatility of the fund’s net asset value and involve the risk that interest costs on money borrowed may exceed the return on securities purchased with that borrowed money. Reverse repurchase agreements are considered to be borrowings by the fund and are subject to the fund’s overall restriction on borrowing, under which it must maintain asset coverage of at least 300%. For the six-month period ended February 28, 2013, the weighted average borrowings outstanding were $8,999,530. The weighted average interest rate paid by the fund on such borrowings was 0.45%.

Repurchase Agreements

For repurchase agreements entered into with certain broker-dealers, the fund, along with other affiliated registered investment companies, may transfer uninvested cash balances into a joint trading account, the daily aggregate balance of which is invested in repurchase agreements secured by U.S. Government or agency obligations. Securities pledged as collateral for all individual and joint repurchase agreements are held by the fund’s custodian bank until maturity of the repurchase agreement. All agreements require that the daily market value of the collateral be in excess of the repurchase amount, including accrued interest, to protect the fund in the event of a default. As of February 28, 2013, the fund had no outstanding repurchase agreements.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported results of operations during the reporting period. Actual results could differ from these estimates.

Events Subsequent to Period End

Management has evaluated fund related events and transactions that occurred subsequent to February 28, 2013, through the date of issuance of the fund’s financial statements. There were no events or transactions that occurred during this period that materially impacted the amounts or disclosures in the fund’s financial statements.

(3) Fees and
Expenses

Investment Advisory Fees

Pursuant to an investment advisory agreement, USBAM, a subsidiary of U.S. Bank National Association (“U.S. Bank”), manages the fund’s assets and furnishes related office facilities, equipment, research, and personnel. The agreement provides USBAM with a monthly investment advisory fee in an amount equal to an annualized rate of 0.65% of the fund’s average weekly net assets. For its fee, USBAM provides investment advice and, in general, conducts the management and investment activities of the fund.

The fund may invest in related money market funds that are a series of First American Funds, Inc., subject to certain limitations. In order to avoid the payment of duplicative investment advisory fees to USBAM, which acts as the investment advisor to both the fund and the related money market funds, USBAM will reimburse the fund an amount equal to that portion of USBAM’s investment advisory fee received from the related money market funds that is attributable to the assets of the fund. These reimbursements, if any, are disclosed as “Fee reimbursements” in the Statement of Operations.

Nuveen Asset Management, LLC (“NAM”) and Nuveen Fund Advisors, Inc. (“NFA”) each serve as investment sub-advisor to the fund pursuant to separate investment sub-advisory agreements with USBAM. NAM makes investment decisions for the fund, places purchase and sale orders for the fund’s portfolio transactions, and employs the fund’s portfolio managers and the securities analysts that provide research services relating to the fund. NFA provides certain other investment sub-advisory services to the fund, including assisting in the supervision of the fund’s investment program, risk monitoring, managing the forms and level of leverage employed

26 AMERICAN INCOME FUND         2013 SEMIANNUAL REPORT

by the fund, assisting in dividend and distribution level determinations, providing tax advice on issues arising in connection with management of the fund’s portfolio, and assisting with pricing of the fund’s portfolio securities. USBAM pays monthly fees to NAM and NFA for the services provided under their respective sub-advisory agreements with USBAM. USBAM pays NAM and NFA a monthly fee at an annual rate of 0.45% and 0.15%, respectively, based upon average weekly net assets.

Administration Fees

USBAM serves as the fund’s administrator pursuant to an administration agreement between USBAM and the fund. Under this administration agreement, USBAM receives a monthly administration fee equal to an annualized rate of 0.10% of the fund’s average weekly net assets. For its fee, USBAM provides numerous services to the fund including, but not limited to, handling the general business affairs, financial and regulatory reporting, and various other services.

Pursuant to a sub-administration agreement between USBAM and NFA, USBAM also pays NFA an annual fee, calculated weekly and paid monthly, equal to 0.05% of the average weekly net assets of the fund for certain administrative and other services that NFA provides to the fund.

Custodian Fees

U.S. Bank serves as the fund’s custodian pursuant to a custodian agreement with the fund. The custodian fee charged to the fund equals an annual rate of 0.005% of average weekly net assets. These fees are computed weekly and paid monthly.

Under this agreement, interest earned on uninvested cash balances is used to reduce a portion of the fund’s custodian expenses. These credits, if any, are disclosed as “Indirect payments from custodian” in the Statement of Operations. Conversely, the custodian charges a fee for any cash overdrafts incurred, which will increase the fund’s custodian expenses. For the six-month period ended February 28, 2013, custodian fees were increased by $34 as a result of overdrafts and reduced by $25 as a result of interest earned.

Other Fees and Expenses

In addition to the investment advisory, administrative, and custodian fees the fund is responsible for paying most other operating expenses, including: legal, auditing and accounting services, postage and printing of shareholder reports, transfer agent fees and expenses, listing fees, outside directors’ fees and expenses, insurance, interest, taxes, and other miscellaneous expenses. For the six-month period ended February 28, 2013, legal fees and expenses of $1,955 were paid to a law firm of which a former Assistant Secretary of the fund had served as a partner through December 31, 2012.

Expenses that are directly related to the fund are charged directly to the fund. Other operating expenses of the First American Family of Funds are allocated to the fund on several bases, including evenly across all funds, allocated based on relative net assets of all the funds within the First American Family of Funds, or a combination of both methods.

(4) Investment
Security
Transactions

Cost of purchases and proceeds from sales of securities, other than temporary investments in short-term securities, for the six-month period ended February 28, 2013, aggregated $163,425,840 and $162,090,137, respectively.

(5) Indemnifications

The fund enters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown. However, the fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
