SEMI-ANNUAL REPORT

JUNE 30, 2012

August 9, 2012

Dear Fellow Shareholders:

YOUR FUND’S PERFORMANCE

Over the first half of 2012 the performance of leveraged bond funds, including Duff & Phelps Utility and Corporate Bond Trust Inc. (the “DUC Fund”), was affected by uncertainties about the resiliency of the U.S. economic recovery and further turmoil in European debt markets. A number of disappointing economic indicators raised the level of concern, causing many investors to turn to the relative safety of high quality fixed income investments. As a result, the DUC Fund along with the broader fixed income markets, posted solid returns.

The following table compares the performance of the DUC Fund to a broad based investment grade bond market benchmark. It is important to note that the index returns stated below include no fees or expenses, whereas the DUC Fund’s NAV returns are net of fees and expenses.

For the period indicated through June 30, 2012	DUC Fund (Per share performance with dividends reinvested in Fund plan)			DUC Fund (NAV based performance)			Barclays Capital U.S. Aggregate Bond Index

DUC Fund per share based returns and DUC Fund NAV based returns were obtained from the Administrator of the DUC Fund. Performance returns for the Barclays U.S. Aggregate Bond Index were obtained from Bloomberg L.P. Past performance is not indicative of future results.

Based on the June 30, 2012 closing price of $12.45 and a monthly distribution of $0.07 per share the DUC Fund common stock had an annualized distribution rate of 6.75%. Please refer to the portion of this letter captioned “ABOUT YOUR FUND” for important information about the sources and characterizations of the DUC Fund’s distributions.

MARKET OVERVIEWAND OUTLOOK

U.S. GDP grew modestly during the first half of 2012. While a decline in energy prices and favorable mortgage rates provided some relief to consumers, persistently high unemployment and a still struggling housing market weighed on consumer sentiment. State and local governments remained under pressure due to weak local economies and reduced federal support, while election year politics added to unpredictability at the national level. Although many corporations enjoyed sound fundamentals, regulatory and fiscal uncertainty caused the business sector to remain cautious and reluctant to use its significant cash reserves to meaningfully increase capital spending or hiring. Recessionary fears in Europe, in part due to austerity measures intended to address the sovereign debt crisis, and the potential for a slowdown in China raised concerns about prospects for global growth.

During the first half of 2012, the Federal Open Market Committee (“FOMC”), the committee within the Federal Reserve that sets monetary policy, reaffirmed its commitment to an accommodative monetary policy. Accordingly, the FOMC held the federal funds rate to a “target range” of zero to 0.25%. Over the first half of the year the U.S. Treasury yield curve shifted downward and became less positively sloped (i.e., long-term rates higher than short-term rates). Yields increased by 6 basis points on two-year maturities, while yields decreased by 23 basis points on ten-year maturities and by 14 basis points on thirty-year maturities. Keeping downward pressure on the long end of the U.S. Treasury yield curve was a recurrence of the “flight to quality” as many investors sought refuge from market volatility in the relative safety of the U.S. Treasury market. Consequently, the higher quality sectors of the broader fixed income markets posted solid returns for the first half of 2012.

1

We believe that the U.S. economy remains on track to have positive albeit moderate growth over the next few quarters. However, in addition to a depressed housing market and only marginal improvement in employment, looming U.S. fiscal tightening and modest growth in the rest of the world is likely to keep the U.S. recovery slow and uneven. The FOMC recently stated that it expects “economic growth to remain moderate over coming quarters and then to pick up very gradually” and acknowledged that “strains in global financial markets continue to pose significant downside risk to the economic outlook”. The FOMC also indicated that longer-term inflation expectations have remained stable and announced the extension of the stimulus program known as “Operation Twist” until the end of the year. Therefore, monetary policy is expected to stay accommodative for the foreseeable future and the need for additional quantitative easing will remain a topic of debate.

If the U.S. economy continues to post sub-par growth and the European sovereign debt crisis remains largely unresolved, investors are likely to vacillate between risk on/risk off modes. As a result, the fixed income market is likely to remain volatile and reactive to the tone of economic data. In the near term, a tepid U.S. economic recovery and moderate inflation expectations are likely to keep U.S. Treasury yields at modest levels. Longer term, a self-sustaining economic recovery and rising inflation expectations could set the stage for upward pressure on interest rates. If that happens, the returns of leveraged bond funds, like the DUC Fund, could be reduced.

ABOUT YOUR FUND

The DUC Fund seeks to provide investors with a stable monthly distribution that is primarily derived from current fiscal year net investment income. At times a portion of the monthly distribution could be derived from realized capital gains, and to the extent necessary, paid-in-capital, in which case the DUC Fund is required to inform shareholders of the sources of the distribution based on U.S. generally accepted accounting principles (“GAAP”). A return of capital distribution does not necessarily reflect the DUC Fund’s investment performance and should not be confused with “yield” or “income”. A return of capital may occur, for example, when some or all of the money that is invested in the Fund is paid back to the investor. Based on GAAP, for the six month period ended June 30, 2012, 60% of the total distributions were attributable to current year net investment income and 40% were in excess of current year net investment income and were therefore attributable to paid-in-capital. The characterization of the distributions for GAAP purposes and federal income tax purposes may differ, primarily because of a difference in the tax and GAAP accounting treatment of amortization for premiums on fixed income securities. As of the date of this letter, for federal income tax purposes the DUC Fund estimates that its current year distributions will be derived entirely from net investment income. In early 2013, a form 1099-DIV will be sent to shareholders which will state the amount and tax characterization of the DUC Fund’s 2012 distributions.

The use of leverage enables the DUC Fund to borrow at short-term rates and invest at long-term rates. As of June 30, 2012, the DUC Fund’s leverage consisted of Auction Market Preferred Shares (“AMPS”) in the amount of $89.575 million and senior debt in the amount of $100.425 million. On that date, the total amount of leverage represented by the AMPS and senior debt constituted approximately 37% of the DUC Fund’s total assets. The amount and type of leverage used is reviewed by the Board of Directors based on the DUC Fund’s expected earnings relative to the anticipated costs (including fees and expenses) associated with the leverage. In addition, the long-term expected benefits of leverage are weighed against the potential effect of increasing the volatility of both the DUC Fund’s net asset value and the market value of its common stock. Historically, the tendency of the U.S. yield curve to exhibit a positive slope has fostered an environment in which leverage can make a positive contribution to the earnings of the DUC Fund. However, there is no assurance that this will continue to be the case in the future. If the use of leverage were to cease being beneficial, the amount and type of leverage employed by the DUC Fund could potentially be modified or eliminated.

Early in 2008, disruptions in the short-term fixed income markets resulted in failures in the periodic auctions and remarketings of many closed-end fund’s preferred shares, including the preferred shares of the the DUC Fund. After reviewing options for resolving preferred share illiquidity, in March 2009 management arranged a $190 million credit facility with a commercial bank. Subsequent to the implementation of the credit facility, the DUC Fund made a draw on the credit facility in the amount of $95 million and redeemed $95 million of AMPS.

In early May 2012, the DUC Fund commenced a voluntary tender offer, seeking to purchase up to $47.5 million of its outstanding AMPS at a price of $24,000 per share, equal to 96% of the $25,000 liquidation preference per share. In mid-June 2012, the DUC Fund accepted for purchase $5.425 million in aggregate liquidation preference (consisting of 217 shares) of AMPS. In order to maintain the same overall leverage following completion of the tender offer, the DUC Fund made an additional draw on the credit facility in the amount of $5.425 million.

2

In July 2012, Moody’s Investors Service, Inc. downgraded the ratings of debt and preferred shares issued by all equity, municipal bond and taxable fixed income closed end funds, including the DUC Fund. The rating actions follow the publication of Moody’s revised methodology for rating debt and preferred securities issued by closed end funds. The revised rating methodology incorporates the impact of market volatility, as experienced in the 2008 financial crisis, on the different types of assets in which funds invest, as well as the leverage, portfolio diversity and other factors. Under the terms of the DUC Fund’s charter the rating change will result in higher dividend rates on the AMPS. Management plans to review the amount and type of leverage employed by the DUC Fund in light of the resultant change in the cost of leverage.

There are a number of factors that continue to constrain the DUC Fund from refinancing additional preferred shares with debt. The DUC Fund is limited in its ability to use debt to refinance all of its outstanding AMPS because of the asset coverage requirements of the Investment Company Act of 1940 and related SEC rules. In addition, the DUC Fund is required to adhere to guidelines established by the two principal rating agencies unless (1) it has received written advice from the applicable rating agency as to the effect that any noncompliance would have on the rating of the AMPS and (2) the Board of Directors has determined, by a 75% vote, that, taking into account the pertinent facts and circumstances, such noncompliance is in the best interests of the DUC Fund. While the DUC Fund’s goal is to provide additional liquidity to preferred shareholders, the Board of Directors and the Adviser continue to believe that any action taken to provide such liquidity should not materially disadvantage common shareholders and their ability to benefit from leverage, should be long-term in nature and should not encumber the investment process or reduce the pool of available investment alternatives. Because of all the foregoing considerations, the amount and timing of any future preferred share redemptions are uncertain. The DUC Fund will announce any redemption through press releases and postings to its website.

The DUC Fund does not currently use derivatives and has no investments in complex securities or structured investment vehicles (“SIVs”). Additionally, the portfolio has no direct exposure to financial intermediaries that focus exclusively on derivatives or SIVs. The DUC Fund’s exposure is indirect and is limited to financial institutions with diversified revenue streams. However, due to the inherent interconnectivity of today’s financial intermediaries, corporate bond investors are faced with the task of identifying and quantifying counterparty risk that is often the result of derivatives positions among both financial and non-financial companies. Government intervention and the potential for additional regulation have also introduced additional uncertainty into the capital structure of various financial intermediaries. In normal market conditions, at least 80% of the DUC Fund’s total assets must be invested in Utility and Corporate Bonds, and at least 25% of the DUC Fund’s total assets must be invested in Utility Income Securities. Due to this mandated exposure, any disruptions in the broader credit market, such as fall-out from the European sovereign debt crisis, could materially and adversely impact the valuation of the investments held in the DUC Fund.

In addition to the risk of disruptions in the broader credit market, an environment of relatively low interest rates adds an element of reinvestment risk to bond funds including the DUC Fund. If bonds held in a portfolio mature during a period of low interest rates, the proceeds may necessarily be reinvested in lower yielding securities. Therefore, a prolonged period of low interest rates and the resultant modest reinvestment opportunities can be expected to adversely impact the earnings of the DUC Fund going forward.

It is impossible for the DUC Fund to be completely insulated from turmoil in the financial markets or adverse levels of interest rates. However, management believes that over the long term the diversification of the portfolio across sectors and issuers, in addition to the conservative distribution of the DUC Fund’s assets along the yield curve, should help limit volatility and reinvestment risk to some degree.

THE ANNUAL SHAREHOLDER MEETING

The annual meeting of the DUC Fund’s shareholders was held on May 10, 2012 at 151 West Adams Street, Chicago, Illinois. At that meeting, holders of the DUC Fund’s common stock re-elected Stewart E. Conner, Eileen A. Moran, and David J. Vitale as directors for terms expiring in 2015. Holders of the DUC Fund’s preferred stock re-elected Nancy Lampton as director for a term expiring in 2015.

3

In addition, the shareholders approved the Board of Directors’ proposal to amend provisions of the DUC Fund’s charter that govern the terms of the Fund’s outstanding AMPS. The Board had recommended approval of the charter amendment in order to give the DUC Fund the flexibility to depart from the rating agencies’ guidelines under certain circumstances as described above.

(a) All or a portion of this security has been segregated and made available for loan.

(b) All or a portion of this security has been loaned.

The percentage shown for each investment category is the total value of that category as a percentage of the net assets applicable to common stock of the Fund.

The Fund’s investments are carried at fair value which is defined as the price that the Fund would receive upon selling an investment in a timely transaction to an

independent buyer in the principal or most advantageous market of the investment. The three-tier hierarchy of inputs established to classify fair value measurements for disclosure purposes is 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, interest rates, prepayment speeds, credit risks, etc.).

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

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in these securities. The following is a summary of the inputs used to value each of the Fund’s investments at June 30, 2012:

	Level 1		Level 2
Asset-backed securities	$	—	$	5,577,037
Corporate bonds		—		482,333,733

NOTES TO FINANCIAL STATEMENTS

June 30, 2012

(Unaudited)

Note 1. Organization

Duff & Phelps Utility and Corporate Bond Trust Inc. (the “Fund”) was incorporated in Maryland on November 23, 1992 as a diversified, closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s investment objective is to seek high current income consistent with investing in securities of investment-grade quality.

Note 2. Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

A. Securities Valuation: Equity securities traded on a national or foreign securities exchange or traded over-the-counter and quoted on the NASDAQ National List are valued at the last reported sale price or, if there was no sale on the pricing date, then the security is valued at the mean of the bid and ask prices as obtained on that day from one or more dealers regularly making a market in that security and are generally classified as Level 1. Equity securities traded on more than one securities exchange shall be valued at the last sale price on the pricing date at the close of the exchange representing the principal market for such securities and are classified as Level 1. Fixed income securities are valued at the mean of bid and ask prices provided by an independent pricing service when such prices are believed to reflect the fair value of such securities and are generally classified as Level 2. Such bid and ask prices are determined taking into account securities prices, yields, maturities, call features, ratings, and institutional size trading in similar securities and developments related to specific securities. Short-term investments having a maturity of 60 days or less at time of purchase are valued on an amortized cost basis, which approximates fair value and are classified as Level 2. Any securities for which it is determined that market prices are unavailable or inappropriate are valued at a fair value using a procedure determined in good faith by the Board of Directors and are generally classified as Level 2 or 3.

B. Securities Transactions and Investment Income: Securities transactions are recorded on the trade date. Realized gains and losses on sales of securities are calculated on the identified cost basis. Dividend income is recorded on the ex-dividend date and interest income is recorded on the accrual basis. The Fund amortizes premiums and accretes discounts on securities using the effective interest method.

C. Federal Income Taxes: It is the Fund’s intention to comply with requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its net taxable income and capital gains to its shareholders. Therefore, no provision for Federal income or excise tax is required. Management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Since tax authorities can examine previously filed tax returns, the Fund’s tax returns for each of the four years in the period ended December 31, 2011 are subject to such review.

D. Dividends and Distributions: The Fund will declare and pay dividends on its common stock monthly from net investment income. Net long-term capital gains, if any, in excess of loss carryforwards are expected to be distributed annually. The Fund will make a determination at the end of its fiscal year as to whether to retain or distribute such gains. Dividends and distributions are recorded on the ex-dividend date. Dividends and distributions on the Fund’s preferred shares are accrued on a daily basis and are determined as described in Note 7.

The amount and timing of distributions are generally determined in accordance with federal tax regulations, which may differ from U.S. generally accepted accounting principles.

E. Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Note 3. Agreements and Management Arrangements

A. Advisor: The Fund has an Advisory Agreement with Duff & Phelps Investment Management Co. (the “Adviser”), a subsidiary of Virtus Investment Partners, Inc. (“Virtus”).

The investment advisory fee is payable monthly at an annual rate of 0.50% of the Fund’s average weekly managed assets, which is defined as the average weekly value of the total assets of the Fund minus the sum of all accrued liabilities of the Fund (other than the aggregate amount of any outstanding borrowings or other indebtedness constituting financial leverage).

B. Administrator: The Fund has an Administration Agreement with J.J.B. Hilliard, W.L. Lyons, LLC (“Hilliard”). The administration fee is payable monthly at an annual rate of 0.14% of the Fund’s average weekly net assets, which is defined as the average weekly value of the total assets of the Fund minus the sum of all accrued liabilities of the Fund (including the aggregate amount of any outstanding borrowings or other indebtedness constituting financial leverage).

C. Directors: The Fund pays each director not affiliated with the Adviser an annual fee plus a fee for certain meetings of the board or committees of the board attended. Total fees paid to directors for the six months ended June 30, 2012 were $69,463.

D. Affiliated Shareholders: At June 30, 2012, Virtus Partners Inc. held 36,117 shares of the Fund. This represents 0.13% of the Fund’s outstanding shares on this date. These shares may be sold at any time.

Note 4. Investment Transactions

Purchases and sales of investment securities (excluding U.S. Government securities and short-term investments) for the six months ended June 30, 2012 aggregated $37,045,103 and $34,494,000, respectively. For the six months ended June 30, 2012, the Fund had purchases and sales of $-0- and $93,326 respectively, of U.S. Government securities.

Note 5. Distributions and Tax Information

At June 30, 2012, the federal tax cost of the Fund’s investments and the aggregate gross unrealized appreciation (depreciation) were as follows:

Federal Tax Cost	Unrealized Appreciation		Unrealized Depreciation			Net Unrealized Appreciation
$474,938,286	$	25,372,617	($	7,614,494	)	$	17,758,123

The tax character of distributions paid during the fiscal year ended December 31, 2011 was as follows:

	12/31/2011
Distributions paid from:
Ordinary income	$	24,342,313
Total distributions	$	24,342,313

15

DUFF & PHELPS UTILITY AND CORPORATE BOND TRUST INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

June 30, 2012

(Unaudited)

The difference between book basis and tax basis unrealized appreciation (depreciation) is attributable primarily to the difference between book and tax amortization methods for premiums and discounts on fixed income securities.

The tax character of the distributions paid in 2012 will be determined at the Fund’s fiscal year end, December 31, 2012.

At December 31, 2011, the Fund had a net capital loss carryforward of $60,855,023 which may be used to offset future capital gains. This net capital loss carryforward will be reduced by future realized capital gains.

Under the Regulated Investment Company Modernization Act of 2010 (the “Act”), net capital losses recognized for tax years beginning after December 22, 2010 may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

At December 31, 2011, the Fund had post-enactment and pre-enactment net capital losses as follows:

			Not Subject to Expiration
	Subject to Expiration		Short Term		Long Term		Total
Carryover loss:	$	53,877,035	$	155,708	$	6,822,280	$	60,855,023
Expiration dates:
2012		3,731,126
2013		3,265,594
2014		4,213,979
2015		13,096,121
2017		18,907,565
2018		10,662,650

Note 6. Reclassification of Capital Accounts

Due to inherent differences in the recognition and distribution of income and realized gains (losses) under U.S. generally accepted accounting principles and for federal income tax purposes, permanent differences between book and tax basis reporting have been identified and appropriately reclassified on the Statement of Assets and Liabilities. At June 30, 2012, the following reclassifications were recorded:

Accumulated net realized loss on investments	Distributions in excess of net investment income
($2,489,099)	$	2,489,099

The reclassifications primarily relate to permanent differences attributable to amortization methods on fixed income securities. These reclassifications had no effect on net assets or net asset value per share.

Note 7. Auction Market Preferred Shares

The Fund’s Charter grants the authority to the Board of Directors to authorize the creation and issuance of one or more series of preferred stock out of the authorized and unissued stock of the Fund. Accordingly, on October 25, 2006, the Fund issued 7,600 shares of Auction Market Preferred Shares (“AMPS”) in two series of 3,800 shares each at a public offering price of $25,000 per share. The underwriting discount and other offering costs incurred in connection with

16

DUFF & PHELPS UTILITY AND CORPORATE BOND TRUST INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

June 30, 2012

(Unaudited)

the issuance of the AMPS were recorded as a reduction of paid-in capital on common stock. Dividends on shares of AMPS are cumulative from their date of original issue and payable on each dividend payment date. On March 24, 2009, the Fund redeemed 3,800 shares of its T7 series of AMPS at liquidation value. During the six months ended June 30, 2012, the Fund conducted a tender offer for its outstanding TH7 series of AMPS and accepted for purchase 217 AMPS, as more fully described in Note 8. As of June 30, 2012, there were 3,583 shares of TH7 series AMPS outstanding.

Under the 1940 Act, the Fund may not declare dividends or make other distributions on shares of common stock or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding preferred stock would be less than 200%.

The AMPS are redeemable at the option of the Fund, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared. The AMPS are also subject to a mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Fund as set forth in the Fund’s Charter are not satisfied.

The holders of AMPS have voting rights equal to the holders of common stock (one vote per share) and will vote together with holders of common stock as a single class. However, holders of AMPS, voting separately as a class, are also entitled to elect two of the Fund’s directors. In addition, the 1940 Act requires that along with any approval by shareholders that might otherwise be required, the approval of the holders of a majority of any outstanding shares of preferred stock, voting separately as a class, would be required to (a) adopt any plan of reorganization that would adversely affect the preferred stock, and (b) take certain actions requiring a vote of security holders, including, among other things, changes in the Fund’s subclassification as a closed-end investment company or changes in its fundamental investment restrictions. Since February 2008, the AMPS market has been ineffective at matching buyers with sellers. This has impacted the Fund’s AMPS. The AMPS dividend rate was reset to the maximum applicable rate. These maximum dividend rates ranged from 1.44% to 1.46% for the six months ended June 30, 2012. A failed auction is not an event of default for the Fund, but it is a liquidity problem for the holders of its AMPS. Dislocations in the auction rate securities markets have triggered numerous failed auctions for many closed-end funds. A failed auction occurs when there are more sellers of AMPS than buyers. It is impossible to predict how long this imbalance will last. A successful auction of the Fund’s AMPS may not occur for a long period of time, if ever. Even if the AMPS market becomes more liquid, the holders of the Fund’s AMPS may not have the amount of liquidity they desire or the ability to sell the AMPS at par.

Note 8. Auction Market Preferred Share Tender Offer

The Fund conducted a tender offer that commenced on May 3, 2012 and expired on June 18, 2012, for up to $47,500,000 of its outstanding AMPS at a price equal to 96% of the per share liquidation preference of $25,000 plus any unpaid dividends accrued through the expiration of the offer. Under the terms of the tender offer on June 18, 2012, the Fund accepted 217 AMPS at a price equal to 96% of its liquidation preference of $25,000 per share ($24,000 per share) plus dividends accrued and unpaid through the expiration of the offer. Because the tender offer was less than the AMPS per share liquidation preference, the tender offer had a positive impact on net asset value in the amount of $217,000, which is reflected in the Statement of Operations under the caption “Benefit to common shareholders from tender offer for auction market preferred shares.”

Note 9. Borrowings

On March 6, 2009, the Fund entered into a Committed Facility Agreement (the “Facility”) with a commercial bank (the “Bank”) that allows the Fund to borrow cash from the Bank, up to a limit of $190,000,000 for the purpose of redeeming shares of preferred stock. Borrowings under the Facility are collateralized by certain assets of the Fund (the “Hypothecated Securities”). The Fund expressly grants the Bank the right to re-register the Hypothecated Securities in its own name or in another name other than the Fund’s and to pledge, repledge, hypothecate, rehypothecate, sell, lend or otherwise transfer or use the Hypothecated Securities. Interest is charged at 3 month LIBOR (London Inter-bank Offered Rate) plus an additional percentage rate on the amount borrowed and a percentage rate on the undrawn balance (the commitment fee). The Fund also paid a one time arrangement fee based on a percentage of the total borrowing limit. Total commitment fees paid for the six months ended June 30, 2012 were $374,365 and are included in Borrowing fees and expenses on the Statement of Operations. The Bank has the ability to require repayment of outstanding borrowings under the Facility upon six months notice or following an event of default. For the six months ended June 30, 2012, the average daily borrowings under the Facility and the weighted daily average interest rate were $95,357,692 and 1.37%, respectively. As of June 30, 2012, the amount of such outstanding borrowings was $100,425,000. The interest rate applicable to the borrowing on June 30, 2012 was 1.31%. The Bank has the ability to borrow the Hypothecated Securities (“Rehypothecated Securities”). The Fund is entitled to receive a fee from the Bank in connection with any borrowing of Rehypothecated Securities. The fee is computed daily based on a percentage of the difference between the fair market rate as determined by the Bank and the Fed Funds Open and is paid monthly. The Fund can designate any Hypothecated Security as ineligible for rehypothecation and can recall any Rehypothecated Security at any time and if the Bank fails to return it (or an equivalent security) in a timely fashion, the Bank will be liable to the Fund for the ultimate delivery of such security and certain costs associated with delayed delivery. In the event the Bank does not return the Rehypothecated Security or an equivalent security, the Fund will have the right to, among other things, apply and set off an amount equal to one hundred percent (100%) of the then-current fair market value of such Rehypothecated Securities against any amounts owed to the Bank under the Facility. At June 30, 2012, Hypothecated Securities under the Facility had a market value of $231,887,734 and Rehypothecated Securities had a market value of $96,193,613. If at the close of business any day, the value of all outstanding Hypothecated Securities exceeds the Hypothecation Limit, the Bank shall promptly, at its option, either reduce the amount of the outstanding securities or deliver an amount of cash at least equal to the excess amount.

Note 10. Indemnifications

Under the Fund’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund enters into contracts that provide general indemnifications to other parties. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these arrangements and expects the risk of loss to be remote.

Note 11. Subsequent Events

Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were available for issuance, and has determined that there were no subsequent events requiring recognition or disclosure in these financial statements.

RENEWAL OF INVESTMENT ADVISORY AGREEMENT (Unaudited)

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the terms of the Fund’s investment advisory agreement must be reviewed and approved at least annually by the Board of Directors of the Fund (the “Board”), including a majority of the directors who are not “interested persons” of the Fund, as defined in section 2(a)(19) of the 1940 Act (the “Independent Directors”). Section 15(c) of the 1940 Act also requires the Fund’s directors to request and evaluate, and the Fund’s investment adviser to furnish, such information as may reasonably be necessary to evaluate the terms of the investment advisory agreement. To assist the Board with this responsibility, the Board has appointed a Contracts Committee, which is composed of three Independent Directors and acts under a written charter that was most recently amended on May 11, 2011. A copy of the charter is available on the Fund’s website at www.ducfund.com and in print to any shareholder, upon request.

The Contracts Committee, assisted by the advice of independent legal counsel, conducted an annual review of the terms of the Fund’s contractual arrangements, including the investment advisory agreement with Duff & Phelps Investment Management Co. (the “Adviser”). Set forth below is a description of the Contracts Committee’s annual review of the Fund’s investment advisory agreement, which provided the material basis for the Board’s decision to continue the investment advisory agreement for a one-year term ending April 30, 2013.

In the course of the Contracts Committee’s review, the members of the Contracts Committee considered all of the information they deemed appropriate, including informational materials furnished by the Adviser in response to a request made by the Contracts Committee. In arriving at its recommendation that continuation of the investment advisory agreement was in the best interests of the Fund and its shareholders, the Contracts Committee took into account all factors that it deemed relevant, without identifying any single factor or group of factors as all-important or controlling. Among the factors considered by the Contracts Committee, and the conclusion reached with respect to each, were the following:

Nature, extent, and quality of services. The Contracts Committee considered the nature, extent and quality of the services provided to the Fund by the Adviser. Among other materials, the Adviser furnished the Contracts Committee with a copy of its most recent investment adviser registration form (Form ADV). In evaluating the quality of the Adviser’s services, the Contracts Committee noted the various complexities involved in the operations of the Fund, such as the use of leverage in the form of auction market preferred shares, borrowings under a credit facility and the rehypothecation of portfolio securities pledged under the credit facility, and concluded that the Adviser is consistently providing high-quality services to the Fund in an increasingly complex environment. The Contracts Committee also acknowledged the unprecedented disruption of the credit and capital markets during the recent period and the commendable skill shown by the Adviser and its personnel in managing the Fund’s portfolio in the face of such extraordinary challenges. The Contracts Committee also considered the length of service of the individual professional employees of the Adviser who provide services to the Fund and noted an almost total lack of turnover. In the Contracts Committee’s view, the long-term service of capable and conscientious professionals provides a significant benefit to the Fund and its shareholders. The Contracts Committee also considered the Fund’s investment performance as discussed below. The Contracts Committee also took into account its evaluation of the quality of the Adviser’s code of ethics and compliance program. In light of the foregoing, the Contracts Committee concluded that it was generally satisfied with the nature, extent and quality of the services provided to the Fund by the Adviser.

Investment performance of the Fund and the Adviser. The Adviser provided the Contracts Committee with performance information for the Fund for various periods, measured against two benchmarks: the Lipper General Bond Funds Average (the Fund’s Lipper category) and the Barclays Capital U.S. Aggregate Index (including the U.S. Credit Index which is a subset of the U.S. Aggregate Index). The Contracts Committee noted that the Fund’s performance generally compared favorably with the benchmarks.

Costs of services and profits realized. The Contracts Committee considered the reasonableness of the compensation paid to the Adviser, in both absolute and comparative terms, and also the profits realized by the Adviser and its affiliates from its relationship with the Fund. To facilitate this analysis, the Contracts Committee retained Lipper Fiduciary

19

Services, an independent provider of investment company data, to furnish a report comparing the Fund’s advisory fee and other expenses to the similar expenses of other bond funds. The Contracts Committee noted that the Fund’s advisory fees, as a percentage of leveraged and non-leveraged assets, were lower than the comparison group median. The Adviser also furnished the Contracts Committee with copies of its financial statements. In reviewing those financial statements, the Contracts Committee examined the profitability of the investment advisory agreement to the Adviser and determined that the profitability of that contract was within the range that courts had found reasonable. The Contracts Committee considered that the Adviser must be able to compensate its employees at competitive levels in order to attract and retain high-quality personnel to provide high-quality service to the Fund. The Contracts Committee concluded that the investment advisory fee was the product of arm’s length bargaining and that it was fair and reasonable to the Fund.

Economies of scale. The Contracts Committee considered whether the Fund has appropriately benefited from any economies of scale. The Contracts Committee concluded that currently the Fund is not sufficiently large to realize benefits from economies of scale with fee breakpoints. However, the Contracts Committee noted that the transition to a single administrator for the complex of three closed-end funds advised by the Adviser had streamlined the operations of the Fund. The Contracts Committee encouraged the Adviser to continue to work towards reducing costs by leveraging relationships with service providers across the complex of funds advised by the Adviser.

Comparison with other advisory contracts. The Contracts Committee also received comparative information from the Adviser with respect to the fees it charges to investment advisory clients other than the Fund. The Contracts Committee noted that, among all accounts managed by the Adviser, the Fund’s advisory fee rate ranks slightly above the median. The advisory fee structure for the Adviser’s other investment company clients ranges from 32 basis points to 100 basis points. The advisory fee structure for the Adviser’s institutional separately managed accounts ranges from 6 basis points for passively managed equity accounts to 85 basis points for actively managed specialized real estate securities accounts. However, the Contracts Committee noted that the services provided by the Adviser to the Fund are significantly more extensive and demanding than the services provided by the Adviser to institutional accounts. Specifically, in providing services to the Fund, the Adviser needs to: (1) comply with the 1940 Act, the Sarbanes-Oxley Act and other federal securities laws and New York Stock Exchange requirements, (2) provide for external reporting (including quarterly and semi-annual reports to shareholders, annual audited financial statements and disclosure of proxy voting), tax compliance and reporting (which are particularly complex for investment companies), requirements of Section 19 of the 1940 Act relating to the source of distributions, (3) prepare for and attend meetings of the Board and its committees, (4) communicate with Board and committee members between meetings, (5) communicate with a retail shareholder base consisting of thousands of investors, (6) manage the use of financial leverage and (7) respond to unanticipated issues such as the recent problems with the preferred stock auction markets. Based on the fact that the Adviser only provides the foregoing services to its investment company clients and not to its institutional account clients, the Contracts Committee concluded that comparisons between the two fee structures would not be appropriate or meaningful.

Indirect benefits. The Contracts Committee considered possible sources of indirect benefits to the Adviser from its relationship to the Fund. As a fixed-income fund, the Contracts Committee noted that the Fund does not utilize affiliates of the Adviser for brokerage purposes.

Based upon its evaluation of all material factors, including the foregoing, and assisted by the advice of independent legal counsel, the Contracts Committee concluded that the continued retention of the Adviser as investment adviser to the Fund was in the best interests of the Fund and its shareholders. Accordingly, the Contracts Committee recommended to the full Board that the investment advisory agreement with the Adviser be continued for a one-year term ending April 30, 2013. On February 21, 2012, the Contracts Committee presented its recommendations, and the criteria on which they were based, to the full Board, whereupon the Board, including all of the independent directors voting separately, accepted the Contracts Committee’s recommendations and unanimously approved the continuation of the current investment advisory agreement with the Adviser for a one-year term ending April 30, 2013.

INFORMATION ABOUT PROXY VOTING BY THE FUND (Unaudited)

Although the Fund does not typically hold voting securities, the Fund’s Board of Directors has adopted proxy voting policies and procedures whereby Duff & Phelps Investment Management Co., the Fund’s investment adviser (the “Adviser”), would review any proxy solicitation materials on a case-by-case basis and would vote any such securities in accordance with the Adviser’s good faith belief as to the best interests of the Fund and its shareholders. These proxy voting policies and procedures may be changed at any time or from time to time by the Fund’s Board of Directors.
