Dear Fellow Shareholders:

   Performance Review: On a long-term basis, as of March 31, 2005, your Fund
had a three-year cumulative total return of 20.3%. In comparison, the S&P
Utilities Index had a total return during that period of 12.1%, 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 total return of 13.9%.

   Your Fund had a total return (market price change plus income) of -8.4% for
the quarter ended March 31, 2005. In comparison, the S&P Utilities Index had a
total return of 5.4%. 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 4.1%.

   During the first quarter of 2005, your Fund paid three monthly 6.5 cent
dividends. The 6.5 cent per share monthly rate, without compounding, would be
78 cents annualized, or a 7.27% common stock dividend yield based on the March
31, 2005 closing price of $10.73 per share. That yield compares favorably with
the quarter-end yields of 3.13% on the Dow Jones Utility Index and 3.38% on the
S&P Utilities Index. Please see the Board of Directors meeting section below
for more information.

   There are a number of reasons why your Fund was unable to produce a positive
total return during the first quarter of 2005. As you know, the primary
objective of your Fund is current income. For this reason, your Fund managers
seek to invest in companies that have the ability to consistently pay and grow
their dividends. During the month of March, the utility stocks that performed
best were companies that are recovering from previous strategic or financial
missteps and currently pay smaller or no dividends, and companies that are
benefiting from temporary, volatile commodity price increases, which alone does
not increase their prospect for consistently paying and growing dividends in
the future. Your Fund was not invested in those companies and, as a result,
underperformed the utilities sector indexes.

   A further reason for your Fund's lower returns during March was the result
of selling pressure on Fund shares over a two day period. Three close but
different levels of stop loss orders created the pressure. A stop loss order is
an instruction by an investor to a broker to sell a stock when a certain price
is reached. Sequential stop loss orders can be triggered in a short time on a
relatively small initial decline in price. The small steps of repeated orders
resulted in a significant decline in the Fund's stock price unrelated to the
price of the utility indexes or their component companies.

   As part of the review of our investment process, each year Fund analysts
prepare industry reviews and outlooks for presentation to the Board of
Directors. These reviews bring into focus certain factors affecting the utility
and REIT industries' operating and financial performance. Following are
highlights from those reviews.

   Telecommunications--Adapting to Changing Industry Conditions: Two key growth
areas for the telecommunications industry, wireless telephony and broadband
services, have been and will continue to be important to telecom companies
around the world. Wireless penetration rates are high in many developed
countries, but the United States lags, indicating there is still plenty of room
for growth in the domestic wireless sector. Outside the U.S., the growth story
is less about increasing subscribers and more about increasing usage, which is
significantly less than in the U.S. Further, wireless data use is in its
infancy in the U.S. and should add a second leg to the growth story.

   Broadband is also a major focus of telecom companies globally. In the U.S.,
telecom company digital subscriber lines (DSL) have more than doubled in two
years. Bundling (the attractive pricing of several services



to a single customer) broadband together with local telephone service is
helping to drive this growth. Bundling is also important because it helps
retain customers and increases the average revenue per customer. Longer term,
retaining broadband customers is key because they are the ones most likely to
take new services, such as video, from telecom companies when such services are
offered in the next year or two.

   Globally, the traditional consumer wireline telephone business remains under
competitive pressure. The pressure began a few years ago with a Federal
Communications Commission (FCC) ruling that allowed competitors to resell the
incumbent Bell companies' own lines at big discounts. Recent court rulings and
regulatory changes have reduced that threat. However, substitution of wirelines
with wireless and voice over Internet protocol (VoIP) is emerging as important
competition for the Bells. At present, there are fewer than one million VoIP
customers in the U.S., but cable companies are beginning to offer VoIP products
and will no doubt take customers from the Bells in the coming years. However,
the fact that the Bells are in most cases the leading wireless providers and
are rapidly growing their broadband base will partly offset the impact of
pressure from cable companies.

   While all had been quiet on the communications mergers and acquisition front
for a few years, consolidation definitely has made a comeback. We believe
consolidation is good for the wireless industry, as it should lead to more
stable pricing, better margins, and less capital spending on what would
otherwise be duplicate networks. Likewise, consolidation is needed in the long
distance business. We have questioned for some time the viability of the long
distance companies on a stand-alone basis. The primary reasons for the mergers
and acquisitions include network synergies, significant cost savings, migration
of voice to an Internet data network, and increased wireless spending by
business enterprises. Hopefully, consolidation will also result in less price
pressure and more stability in what has been a very volatile market.

   Despite the competitive challenges to the traditional telecommunication
service providers, cash generation remains robust. Shareholders have benefited
in the form of increasing dividends, a trend we expect to continue. For DNP
shareholders, investment in these companies provides value through dividend
income and the growth of that income. Therefore, we anticipate continued
participation in incumbent telecom companies around the world.

   Electric Utilities--Dividend Growth is Back: During 2004 and into 2005, the
electric utility industry has been dominated by news of rising interest rates
and increasing commodity prices. On the surface, rising rates and high
commodity prices might give utility investors reason for caution. However, the
"measured pace" of interest rate increases by the Federal Reserve, and
favorable business positions of many companies have provided comfort to utility
investors and shifted their focus to the improving industry fundamentals.

   Many electric companies have not been materially impacted by higher
commodity prices. Long-term contracts, hedging activities, and state regulated
cost recovery programs have enabled some companies to neutralize the impact of
higher coal and gas costs. Companies affected the most by high commodity prices
have been those with newly constructed non-regulated gas-fired plants. These
plants have been uneconomic because high gas costs offset the potential
financial benefits of higher electricity prices. However, several companies
with uncommitted output from low cost nuclear and coal plants have been able to
benefit financially from the higher level of electricity prices. We expect the
high commodity price environment to persist in 2005.

   Congress failed to pass comprehensive energy legislation in 2004. But the
electric component of the energy bill is still alive and there is some
possibility for legislation in 2005. We believe that the bill would spur much
needed investment in the electric transmission system and lead to improved
system reliability.

                                      2



   Important for investors, 2004 was the year that utility managements' "back
to basics" strategies literally began to pay dividends. In general, management
focus was, and continues to be, on core-regulated operations. With non-core and
frequently less profitable activities minimized, only modest ongoing levels of
construction spending planned, and generally positive regulatory decisions for
rate increases received, many companies chose to return excess cash to
investors. During 2004, common stock dividend rates were significantly
increased. In fact, more than ten companies implemented double digit dividend
increases, and three companies actually increased their dividends twice during
the year. We will continue to position our electric holdings to take advantage
of the improved dividend environment.

   Natural Gas Utilities--Price and Supply Remain Issues: The price of natural
gas and concerns about the ability of natural gas supply to meet increasing
demand dominated industry headlines in 2004. For the near- to medium-term, we
believe natural gas prices are likely to remain high, and could be quite
volatile, as production from existing wells wanes and additional supply is more
difficult (and expensive) to come by. Over the long-term, new supply sources
will develop, such as expanded and new liquefied natural gas (LNG) facilities.
By first converting natural gas to a liquid for transportation, and then
converting the liquid back to a gas, LNG plants make the importation of natural
gas from other countries economic. Expansions of existing facilities will start
to come on line in the next year or two, but new LNG facilities will take much
longer to become operational. In the meantime, technological changes may allow
more gas to be recovered from existing sources, unconventional supplies may be
developed, and new geographic areas may be opened for exploration.

   Over the past several years, local gas distribution companies have faced
many of the same challenges as companies in other industries - higher expenses
from pensions, health-related benefits, insurance, and security. Managements
have done a good job of controlling the costs that they are able to control.
Still, there has been pressure on margins because of the overhead that
managements could not influence. Consequently, we expect to see more regulatory
rate cases filed this year as companies seek recovery of the higher expenses
they have been absorbing. We believe state regulators are well aware of the
issues facing local gas utilities and will be fair in allowing rates to reflect
the additional cost burdens.

   The stock performance of local gas distribution utilities was not uniform in
2004. In general, the stock prices of the lowest yielding companies did better
than higher yielding companies. Relative performance can be a cyclical
phenomenon, and in this case the companies with lower yields tended to have
greater commodity price exposure and, in a rising and volatile price
environment, benefited the most. Given the Fund's income objective, we believe
that it is appropriate to maintain our emphasis on low-risk companies with
steady growth rates that can sustain or grow their dividends annually.

   REITs--Diversification and Yield: 2004 was the eleventh year REITs have been
in your Fund. REITs are used to complement Fund utility equities because REIT
yields are among the highest in the equity market and historically have been
secure. The National Association of Real Estate Investment Trusts (NAREIT)
Equity Index finished last year with a yield of 4.7%. Over the long-term, the
majority of the return from the NAREIT Equity Index has been generated from
income. We believe this trend will continue in the future.

   REITs provide an opportunity to diversify the Fund's portfolio and reduce
risk. Studies reported by Ibbotson Associates indicate that REITs provide
meaningful diversification benefits to portfolios. Because REIT total returns
have historically behaved differently than the returns of large stocks, small
stocks, international stocks, and long-term government bonds, total portfolio
return is smoothed and risk reduced with the inclusion of REITs.

                                      3



   Your Fund's REIT holdings are diversified among the 13 different property
sectors that make up the REIT sector. At any given time some property types may
demonstrate absolute or relative operating strength while others demonstrate
absolute or relative weakness. In 2005 we are seeing a continued strengthening
of fundamentals in more cyclical property sectors such as lodging, industrial,
office, apartments, and self-storage. While these sectors typically benefit
from an improving economy, some sectors, such as lodging and industrial, can
benefit from increased business activity without significant job growth. In
addition to the improvement we are seeing in the more cyclical property
sectors, the strength in regional malls and shopping centers continues. Your
Fund managers anticipate that REITs will continue to add value to the portfolio
over the long-term.

   Annual Meeting of Shareholders: Claire V. Hansen retired as a director and
chairman of your Fund at the annual meeting of shareholders on May 23, 2005.
Mr. Hansen, who first began work with the former Duff & Phelps Corporation in
1959, is the Fund's founding chairman and has served as chairman and director
of the Fund since it was first organized in 1986. The Fund expresses its
deepest appreciation for Mr. Hansen's dedicated service and distinguished
leadership over the past decades and wishes him well in his retirement.

   Also at that meeting Connie K. Duckworth and Carl F. Pollard were reelected
as directors of the Fund. The retirement of Chairman Hansen and the
renomination of only two directors reflect the Board's decision to reduce the
size of the Board from nine to eight directors.

   Board of Directors Meeting: At the regular May 2005 Board of Directors'
meeting, the Board elected Vice Chairman Francis E. Jeffries to be the new
Board Chairman. Mr. Jeffries has been a director of the Fund since its
inception in 1987. The Board also declared the following monthly dividends:



                    Cents Per Share Record Date Payable Date
                    --------------- ----------- ------------

                          6.5        August 31  September 12


   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.

   At the February 2005 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 near 40-year lows despite recent Federal Reserve actions
and utility common stock dividends 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. In addition, the reduced
use of short-term trading strategies by the Fund has lowered the Fund's
portfolio turnover rate and transaction costs. 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.

--------
(1)The market values for securities are determined as follows: Equity
   securities traded on a national securities exchange or traded
   over-the-counter and quoted on the NASDAQ System are valued at last sales
   prices. Fixed income securities and any other 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 which includes the use of a pricing service. Each money market
   instrument having a maturity of 60 days or less is valued on an amortized
   cost basis, which approximates market value.

(2)At December 31, 2004, the Fund's most recent fiscal tax year end, based on a
   tax cost of investments of $2,776,340,015, the Fund had gross unrealized
   appreciation of $365,962,302 and unrealized depreciation of $32,560,868.
