ITEM 1. REPORTS TO STOCKHOLDERS.
   
  The Semi-Annual Report to Stockholders follows.


Dear Fellow Shareholders:

     Performance Review: Consistent with its primary objective of current income, the Fund paid three monthly dividends of 6.5 cents per share during the second quarter. The 6.5 cent per share monthly rate, without compounding, would be 78 cents annualized, or a 7.65% common stock dividend yield based on the June 30, 2006, closing price of $10.20 per share. That yield compares favorably with the June 30 yields of 3.20% on the Dow Jones Utility Index and 3.31% on the S&P Utilities Index.

     Your Fund had a total return (income plus change in market price) of -0.4% for the quarter ended June 30, 2006. In comparison, the S&P Utilities Index had a total return of 5.7%. A composite of the S&P Utilities Index and the Lehman Utility Bond Index, reflecting the stock and bond ratio of the Fund, had a total return of 3.8%.

     On a longer-term basis, as of June 30, 2006, your Fund had a five-year cumulative total return of 40.4%. In comparison, the S&P Utilities Index had a cumulative total return during that period of 6.5%, while a composite of the S&P Utilities Index and the Lehman Utility Bond Index, reflecting the stock and bond ratio of the Fund, had a cumulative total return of 10.9%.

     Trends in Federal Monetary Policy: In our letters to shareholders over the last several years, we have periodically commented about trends in the economic environment that affect the Fund. The following is a summary of historical and present trends in federal monetary policy.

     The Federal Reserve (Fed) currently has two legislated objectives—price stability and full employment. In a 2001 speech entitled Transparency in Monetary Policy, Former Federal Reserve Chairman Greenspan said that not only did the Fed need to implement an effective monetary policy to meet legislated objectives, but also needed to do so in a “most open and transparent manner.”

     The concept of monetary policy transparency implies a clear and widely disseminated statement of situation-specific policy goals, the indicators that will motivate policy action, and the instruments best suited to achieve those goals. The purpose of transparency is to provide information to the public, business, and the financial markets that will improve expectations of future policy actions and the state of the economy. The more all of us know about the circumstances under which we make our daily decisions, the better the outcomes will be.

     The Fed and its policy-setting arm, the Federal Open Market Committee (FOMC), do not have a long history of monetary policy communication. The FOMC only began its current practice of immediately announcing its policy decisions in 1994. The press release at that time noted that the FOMC had “decided to increase slightly the degree of pressure on reserve positions.” It was not until 1995 that FOMC press releases began to make explicit reference to changes in the federal funds target rate, such as: “Today’s action will be reflected in a 25 basis point decline in the federal funds rate.”

     In 1999, the FOMC begin releasing announcements following each meeting even if there were no changes in its policy, and announcements included a description of economic conditions and an indication of the likely direction of the next policy move. For example: “The Committee was concerned about the potential for a buildup in inflationary imbalances that could undermine the favorable performance of the economy and therefore adopted a directive that is tilted towards the possibility of a firming in the stance of monetary policy.” In 2000, “tilt” was replaced with a more complete statement describing the “balance of risks” to the economic outlook, and in 2002 the FOMC began releasing the votes of individual members and the strategy preferred by dissenting members.


     When in 2003 the Fed perceived a threat of disinflation, the FOMC said that it expected to maintain its low federal funds rate for a “considerable period”—a clear indication that the public should not expect a policy change in the near term. When the threat of disinflation was judged to have passed in 2004, the FOMC said that its low-rate monetary policy could be “removed at a measured pace”—clear evidence that interest rates were going to rise slowly and predictably. Last December, the FOMC modified the form of its announcement to state that “some further measured firming might be required,” and in January 2006, the word “measured” was eliminated—a signal that the timing and magnitude of future actions would be less certain.

     In May of this year, the Fed began communicating that future policy actions “will depend on the evolution of the outlook for both inflation and economic growth, as implied by incoming information.” Such a real-time data dependent monetary policy brings us to the current situation of transparency without certainty. Because the Fed’s dual goals of price stability and economic growth are at times inherently conflicting, until current concerns about these goals are resolved, future policy action expectations remain subject to uncertain forecasts.

     Although your Fund managers believe that the Fed is likely to stop raising rates in the near future, we note that your Fund’s investment objectives and policies provide several advantages in uncertain times. As you know, the Fund’s primary investment objectives are current income and long-term growth of income. Capital appreciation is a secondary objective. The Fund seeks to achieve its investment objectives by investing primarily in a diversified portfolio of equity and fixed income securities of companies in the public utilities industry. Accordingly, the equity securities in your Fund’s portfolio are from companies that have established a reputation for paying regular dividends and for increasing their dividends over time. It is widely acknowledged that regular dividends play a major role in moderating investment risk. Your Fund also invests in bonds and preferred stocks. Fixed income securities must generally be rated investment grade at the time of purchase, and the Fund’s fixed income portfolio is diversified as to maturity and issuer. In summary, regardless of the uncertain investment environment, your Fund managers will continue to pursue current income from quality companies.

     Board of Directors’Actions: At the regular May 2006 Board of Directors meeting, the Board increased from 15% to 20% the percentage of the Fund’s total assets that may be invested in securities issued by public companies outside the United States. With the increasing globalization of the financial markets and the advantageous dividend attributes of selected foreign utility issues, the Board felt that an increase in the Fund’s potential foreign exposure was warranted. The Board had previously increased the permitted percentage of foreign investments in 1998 from 10% to 15%.

     In July 2006 your Fund issued $200 million of Auction Preferred Stock (APS). The July issuance completed the $500 million total issuance of APS authorized by the Board. The proceeds from the offerings were used to retire the Fund’s $200 million commercial paper program and to increase the Fund’s total assets available for investment. The APS issues are rated AAA by Standard & Poor’s and Aaa by Moody’s Investors Service, which is consistent with the Fund’s outstanding Remarketed Preferred Stock. (Rating agencies point out that their ratings are statements of opinion and are not recommendations to purchase, sell, or hold any securities.)

     At the regular August 2006 Board of Directors’ meeting, the Board declared the following monthly dividends:

  Cents Per Share    Record Date    Payable Date   
 


 
  6.5      September 29     October 10  
  6.5      October 31     November 10  
  6.5      November 30     December 11  

     The determination of the character of all Fund distributions (specifying which portion is ordinary income, qualifying dividend income, short or long term capital gains, or return of capital) is made each year-end and is reported to shareholders on Form 1099-DIV, which is mailed every year in late January or early February.

     At the February 2006 Board of Directors meeting, the Board reviewed the Fund’s dividend policy and reaffirmed the current 6.5 cents per share per month dividend rate. Interest rates remain historically low despite recent Federal Reserve actions, and utility common stock dividend yields are well below their long-term average. Since 2004, the Fund has made increased use of realized gains to supplement its investment income and has reduced its use of short-term trading strategies designed to capture dividend income. Until the Fund utilizes all of its tax loss carryforwards, distributions to shareholders derived from realized gains will be treated as ordinary income for tax purposes. Once the Fund utilizes all of its tax loss carryforwards and, in the absence of an increase in the yields available on Fund investments and/or realizable gains on Fund investments, the Fund’s dividend distributions may include a portion of non-taxable return of capital in order to maintain the dividend rate.

     Automatic Dividend Reinvestment Plan and Direct Deposit Service—The Fund has a dividend reinvestment plan available as a benefit to all registered shareholders and also offers direct deposit service through electronic funds transfer to all registered shareholders currently receiving a monthly dividend check. These services are offered through The Bank of New York. For more information and/or an authorization form on automatic dividend reinvestment or direct deposit, please contact The Bank of New York (1-877-381-2537 or http://stock.bankofny.com). Information on these services is also available on the Fund’s web site at the address noted below.

(1) Upon the adoption of FAS 150 in 2003, dividends on the Fund’s remarketed preferred stock are included in interest 
expense and are part of net investment income. Absent this change in accounting, per share net investment income and 
dividends on the remarketed preferred stock would have been $0.27 and $0.06, respectively for the six months ended 
June 30, 2006, and $0.47 and $0.06, respectively in 2005, $0.58 and $0.03, respectively in 2004 and $0.78 and $0.03, 
respectively in 2003. 
   
(2) Beginning in 2004, the Fund reduced its use of short-term trading strategies designed to capture dividend income and 
made increased use of realized gains to supplement its investment income. Until the Fund utilizes all of its tax loss 
carryforwards, distributions to shareholders derived from such realized gains will be treated as ordinary income for tax 
purposes. In addition, the reduced use of short-term trading strategies reduced the Fund’s portfolio turnover rate during 
the six months ended June 30, 2006 and the years ended December 31, 2005 and 2004.

NOTES TO FINANCIAL STATEMENTS
(UNAUDITED)
June 30, 2006

(1) SIGNIFICANT ACCOUNTING POLICIES:

     DNP SELECT INCOME FUND INC. (the “Fund”) was incorporated under the laws of the State of Maryland on November 26, 1986. The Fund commenced operations on January 21, 1987, as a closed-end diversified management investment company registered under the Investment Company Act of 1940. The primary investment objectives of the Fund are current income and long-term growth of income. Capital appreciation is a secondary objective.

The following are the significant accounting policies of the Fund:

     (a) Equity securities traded on a national or foreign securities exchange or traded over-the-counter and quoted on the NASDAQ System 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. 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 market value of such securities. 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. 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. Short-term investments having a maturity of 60 days or less are valued on an amortized cost basis, which approximates market value.

     (b) Repurchase agreements are fully collateralized by U.S. Treasury, U.S. Government Agency and other investment grade securities. All collateral is held by an independent third-party custodian bank on behalf of the Fund until maturity of the repurchase agreement. Provisions of the agreement provide that the market value of the collateral plus accrued interest on the collateral is greater than or equal to the repurchase price plus accrued interest at all times. In the event of a default or bankruptcy by the other party to the agreements, the Fund maintains the right to sell the underlying collateral securities at market value; however realization and/or retention of the collateral may be subject to legal proceedings.

     (c) It is the Fund’s policy to comply with requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for Federal income taxes is required. The Fund intends to utilize provisions of Federal income tax laws which allow a realized capital loss to be carried forward for eight years following the year of loss. At December 31, 2005, the Fund had tax capital loss carry forwards of $251,042,613 of which $38,794,764 will expire in 2010 and $212,247,849 will expire in 2011. These capital loss carryforwards will be reduced by future realized gains, whether or not distributed (see Note 4). The Fund incurred net losses associated with certain securities in November and December 2005 of $147,908 which were deferred for tax purposes and treated as if they were incurred on January 1, 2006.

     At December 31, 2005, on a tax basis, the Fund had undistributed net investment income of $0 and based on a $3,010,132,491 tax cost of investments, gross unrealized appreciation of $362,153,165 and

19


DNP SELECT INCOME FUND INC.
NOTES TO FINANCIAL STATEMENTS—(Continued)
(UNAUDITED)
June 30, 2006

unrealized depreciation of $83,919,490. The difference between the book basis and tax basis of distributable earnings and cost of investments are primarily a result of tax deferral of wash sale losses, the accretion of market discount and amortization of premiums and alternative tax treatment of certain securities.

     (d) Security transactions are recorded on the trade date. Realized gains or losses from sales of securities are determined on the specific identified cost basis. Dividend income is recognized on the ex-dividend date. Interest income and expense are recognized on the accrual basis. Discounts and premiums on securities are amortized over the lives of the respective securities for financial reporting purposes. Discounts and premiums are not amortized for tax purposes.

     (e) The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

(2) MANAGEMENT ARRANGEMENTS:

     The Fund has engaged Duff & Phelps Investment Management Co. (the “Adviser”) to provide professional investment management services for the Fund and has engaged J. J. B. Hilliard, W. L. Lyons, Inc. (the “Administrator”) to provide administrative and management services for the Fund. The Adviser receives a quarterly fee at an annual rate of .60% of the average weekly net assets of the Fund up to $1.5 billion and ..50% of average weekly net assets in excess thereof. The Administrator receives a quarterly fee at annual rates of .25% of average weekly net assets up to $100 million, .20% of average weekly net assets from $100 million to $1 billion, and .10% of average weekly net assets over $1 billion. For purposes of the foregoing calculations, “average weekly net assets” is defined as the sum of (i) the aggregate net asset value of the Fund’s common stock (ii) the aggregate liquidation preference of the Fund’s preferred stock and (iii) the aggregate proceeds to the Fund of commercial paper issued by the Fund. Directors of the Fund not affiliated with the Adviser receive a fee of $25,000 per year plus $2,000 per board meeting, plus $1,500 per committee meeting attended. Committee chairmen receive an additional fee of $5,000 per year. The chairman of the board receives an additional fee of $50,000 per year. Total fees paid to directors for the six months ended June 30, 2006 were $209,000.

(3) 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 contracts and expects the risk of loss to be remote.

(4) DIVIDENDS:

     The Fund declares and pays dividends monthly. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Distributions from and in excess of net investment income on the Statements of Changes in Net Assets consists of ordinary income distributions for federal income tax purposes. Ordinary income distributions for federal income tax purposes include distributions from net investment income and distributions derived from realized gains, until the Fund utilizes all of its tax loss carryforwards.

     The tax character of all Fund distributions in 2005 was as follows:

     
Ordinary Income 
  Return of Capital   
 

 
 
2005 
 
$167,196,945 
  $7,616,135   

     The tax character of all Fund distributions for the year ending December 31, 2006 will be determined at the end of the current fiscal year.

     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. The reclassifications primarily relate to premium amortization and capital loss carryforwards utilized for current year distributions. These reclassifications have no impact on the net asset value of the Fund. At June 30, 2006 the following reclassifications were recorded:

  Accumulated net realized    Distributions in excess of   
Paid-in Surplus
  loss on investments    net investment income   
 
 

 
 
($37,389,907)
  $3,828,598    $33,561,309   

(5) PREFERRED STOCK:

     The Fund is authorized to issue 100,000,000 shares of preferred stock with a par value of $.001. In 1988, the Fund issued 5,000 shares of Remarketed Preferred Stock (“RP”) in five series of 1,000 shares each at a public offering price of $100,000 per share. In 2006, the Fund issued 12,000 shares of Auction Preferred Stock (“APS”) in three series of 4,000 shares each at a public offering price of $25,000 per share. The underwriting discount and other offering costs incurred in connection with the issuance of the RP and APS were recorded as a reduction of paid-in surplus on common stock. Dividends on the RP and APS are cumulative at a rate which was initially established for each series at the time of its initial offering. Since the initial offering of each series of RP and APS, the dividend rate on each series of RP has been reset every 49 days by a remarketing process and the dividend rate on each series of APS has been reset every seven days by an auction process. Dividend rates ranged from 3.47% to 4.47% on the RP and from 4.57% and to 5.26% on the APS during the six months ended June 30, 2006.

     The RP and APS are redeemable at the option of the Fund on any dividend payment date at a redemption price equal to $100,000 per share for each share of RP and $25,000 per share for each share of APS, plus

21


DNP SELECT INCOME FUND INC.
NOTES TO FINANCIAL STATEMENTS—(Continued)
(UNAUDITED)
June 30, 2006

accumulated and unpaid dividends in each case. The Fund is required to maintain certain asset coverage with respect to the RP and APS, and the RP and APS are subject to mandatory redemption if that asset coverage is not maintained. Each series of RP is also subject to mandatory redemption on a date certain as follows: Series A - November 28, 2012; Series B - November 18, 2015; Series C - November 7, 2018; Series D - December 22, 2021; and Series E - December 11, 2024.

     In general, the holders of the RP and of the Common Stock have equal voting rights of one vote per share and the holders of the APS are entitled to one quarter of a vote per share. Since each share of APS represents a liquidation preference of $25,000, and each share of RP represents a liquidation preference of $100,000, the allocation of one quarter of a vote per share to the APS gives all holders of preferred stock equal voting power per dollar of liquidation preference. The holders of the RP and APS, together as a class, vote to elect two members of the Board of Directors, and separate class votes are required on certain matters that affect the respective interests of the RP and APS and the Common Stock.

     On July 18, 2006, the Fund issued two additional series of APS having an aggregate liquidation preference of $200,000,000.

(6) COMMERCIAL PAPER:

     As of January 1, 2006, the Fund had Commercial Paper Notes (“Notes”) outstanding with a par value of $200,000,000 and had entered into a credit agreement to provide liquidity. The Notes were unsecured, general obligations of the Fund. During the period ended May 31, 2006, the Fund decreased the amount of its outstanding Notes to zero. Interest rates on the Notes ranged from 4.37% to 4.80% during the period from January 1, 2006 through May 31, 2006. As of June 1, 2006, the Fund no longer issues such Notes and has terminated the related backup credit facility.

(7) INVESTMENT TRANSACTIONS:

     For the six months ended June 30, 2006 purchases and sales of investment securities (excluding short-term securities) were $682,150,023 and $599,190,991, respectively.

     The Fund may lend portfolio securities to a broker/dealer. Loans are required to be secured at all times by collateral at least equal to the market value of securities loaned. The Fund receives a portion of the income earned on the securities held as collateral and continues to earn income on the loaned securities. Security loans are subject to the risk of failure by the borrower to return the loaned securities in which case the Fund could incur a loss. At June 30,2006 the Fund had loaned portfolio securities with a market value of $702,463,712 and received $724,182,153 of cash collateral. This cash was invested in securities as shown in the Schedule of Investments.

Renewal of Investment Advisory Agreement

     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 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. The Board has a Contracts Committee, composed entirely of Independent Directors, which, assisted by the advice of independent legal counsel, conducts an annual review of the terms of the Fund’s contractual arrangements, including the Fund’s investment advisory agreement with Duff & Phelps Investment Management Co., the Fund’s investment adviser (the “Adviser”). In the course of that 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 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 Committee considered the nature, extent and quality of the services provided to the Fund by the Adviser. In evaluating the quality of the Adviser’s services, the Committee noted the various complexities involved in the operations of the Fund, such as the use of two types of leverage and the lending of portfolio securities, and concluded that the Adviser is consistently providing high-quality services to the Fund in an increasingly complex environment. The 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 Committee’s view, the long-term service of capable and conscientious professionals provides a significant benefit to the Fund and its shareholders. The Committee also considered the Fund’s investment performance as discussed below. In light of the foregoing, the Committee concluded that it was 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 Committee reviewed the Fund’s investment performance over time and compared that performance to various peer groups and indices. The Committee concluded that since current income is the Fund’s primary objective, one of the best measures of the Adviser’s performance is the Fund’s consistent ability to pay a 6.5 cent per share monthly dividend. The Committee also considered the fact that since 1990, shares of the Fund have traded at a premium to net asset value 94.5% of the time even though shares of most closed-end funds trade at a discount to net asset value as further evidence of the Adviser’s successful management of the Fund’s investment portfolio.

     Cost of services and profits realized. The 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 Committee retained Lipper Analytical Services Inc., 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 comparable funds. The Committee noted that many of the other funds in the comparison group were only recently established, and benefited from waivers

23


Renewal of Investment Advisory Agreement—(Continued)

of advisory fees by their sponsors. The Committee’s view is that gross fees provide a more useful comparison because waivers tend to be associated with the launch of new funds and can be expected to be of short duration. The Fund’s fees, while higher than the comparison group median when waivers were included, were lower than the median when waivers were excluded. The Committee also received comparative information from the Adviser with respect to the fees it charges to investment advisory clients other than the Fund. However, the Committee concluded that the services rendered to other institutional investor clients were not sufficiently comparable to the services rendered to the Fund for a direct comparison of advisory fees to be meaningful. The Committee also examined the profitability of the investment advisory agreement to the Adviser and determined that the profitability was within the range that courts had found reasonable. The 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 Committee concluded that the investment advisory agreement was the product of arm’s length bargaining and that it was fair and reasonable to the Fund.

     Economies of scale. The Committee considered whether the Fund has appropriately benefited from any economies of scale. The Committee noted the breakpoints whereby the advisory fee is reduced at higher asset levels and concluded that any economies of scale are being shared between Fund shareholders and the Adviser in an appropriate manner.

     Indirect benefits. The Committee considered the indirect benefits the Adviser derives from its relationship with the Fund, including brokerage and soft dollar arrangements. In this regard, the Committee noted that the Fund does not utilize affiliates of the Adviser for brokerage purposes, that the Adviser had significantly reduced the Fund’s brokerage cost in recent years and that the Adviser was in the process of phasing out the use of soft dollar arrangements.

     The Contracts Committee concluded, based upon its evaluation of all material factors, including the foregoing, and assisted by the advice of independent legal counsel, that the existing advisory fee structure is fair and reasonable, and recommended the continuation of the investment advisory agreement as being in the best interests of the Fund and its shareholders. On February 24, 2006, the Committee presented its recommendation, and the criteria on which it was based, to the full Board, whereupon the Board, including the Independent Directors, accepted the Committee’s recommendation and approved the continuation of the Fund’s investment advisory agreement for an additional one-year term ending April 30, 2007.
