Fellow Shareholders

The past six months were favorable for investment-grade bonds and your fund as
long-term bond prices rallied in response to falling yields. Although the
Federal Reserve raised its target for the key federal funds rate four times in
the period, your portfolio's defensive posture and focus on intermediate- and
longer-term securities benefited results. The New Income Fund posted solid
returns for six and 12 months that compared favorably with its Lipper peer group
average.

MARKET ENVIRONMENT

Short- and long-term Treasury yields moved in opposite directions in the
six-month period ended November 30, 2004. As anticipated, the Federal Reserve
repeatedly nudged short-term interest rates higher--in four quarter-point
increments since June 30--in response to a sustained economic expansion. The
federal funds target rate has doubled from a multi-decade low to 2.0%, and
short-maturity fixed-income yields have responded in kind. For example, the
yield on the three-month Treasury bill rose 116 basis points (100 basis points
equal 1.0%) to 2.22% over the past six months. (The Federal Reserve raised rates
another quarter point to 2.25% on December 14, following the end of our
reporting period.)

Nevertheless, long-term bond yields fell in the first half of your fund's fiscal
year (although rates spiked in November) due to job market weakness, a squeeze
on consumers from sharply rising oil prices, and continued geopolitical
uncertainty. From this year's high near 5.35% (at the end of May), the yield on
the 30-year Treasury note dipped to 5.00% at the end of the reporting period.
The yield on the 10-year Treasury note, which is closer to the portfolio's
weighted average maturity, declined a similar amount, to 4.35% from 4.65%, over
the last six

<PAGE>

months. The combination of rising short-term yields and falling longer-term
yields resulted in a flattening (or pivoting) of the yield curve. (The yield
curve is a graphic depiction of interest rates for bonds of the same quality
with various maturities.) Since May, long-term securities--the "back end" of the
curve--dramatically outperformed short-term issues--the "front end." We think it
is likely that longer-term yields will increase in coming quarters but that the
yield curve will continue flattening as short rates rise more than those further
out the curve.

Intermediate- and long-term bonds posted strong gains for the past six months as
price gains augmented interest income. Overseas credits, particularly in
emerging markets, generated the best results as the dollar fell and world
economic growth resumed. Corporate bonds, especially lower-quality credits,
generated good results as well, helped by economic strength, improving profit
trends, and continuing balance sheet repair. Mortgage-backed securities
outperformed other comparable government securities as prepayment volatility
subsided. Treasury inflation-protected securities (TIPS) also produced strong
returns. The dollar's weakness, fears relating to energy-induced inflation, and
the rising CPI helped boost demand for TIPS, especially by institutional
investors, who have added the class to their asset allocation to enhance
diversification and hedge inflation risks. Asset-backed and government agency
securities, which have minimal default risk, lagged the Lehman Brothers U.S.
Aggregate Index, a broad measure of the domestic investment-grade bond market,
but outperformed similar-maturity Treasuries.

PERFORMANCE REVIEW

The New Income Fund generated a solid 4.10% six-month gain for the period ended
November 30, 2004. The portfolio outperformed the Lipper

<PAGE>

average for similar funds and the Lehman Brothers U.S. Aggregate Index. In the
past six months, we emphasized longer maturity debt--the long end of the
curve--while maintaining a defensive posture through purchases of floating-rate
notes on the short end and increasing diversification in nondollar-denominated
securities. We concentrated purchases especially in Canada and in newly
developed markets such as Mexico and Poland where yields are significantly
higher than in the U.S. Returns for the 12-month period were also better than
both of our benchmarks. Performance for the Advisor Class and R Class will vary
due to their differing fee structures.

As we wrote six months ago, fundamental credit research and broader market
themes play a major role in determining our individual security selections and
sector allocations. Improving credit trends and stronger economic growth
supported our commitment to corporate bonds in the utility, industrials, and
energy sectors. The fund continues to overweight lower-quality, investment-grade
(BBB rated) credits, and, in anticipation of higher short-term rates, we
increased our positions in floating-rate notes. This positioning allowed the
portfolio to generate slightly more income in the first half of the current
fiscal year than in the prior six-month period, and that income generation is
reflected in the higher 30-day standardized yield. Over the past six months the
portfolio's weighted average maturity notched higher to 7.1 years from 6.7
years, but because of our concern about rising interest rates, we maintained the
portfolio's defensive 4.4-year duration. (Duration is a measure of a bond fund's
sensitivity to interest rates; for example, a fund with a four-year duration
should rise or fall approximately 4% for each one-percentage-point fall or rise
in interest rates.) Our defensive posture also led us to underweight the
highest-quality corporate bonds, which are acutely sensitive to changes in
underlying U.S. Treasury yields.


<PAGE>

STRATEGY

The beginning of the long-awaited Fed campaign to raise short-term interest
rates set the tone for our portfolio positioning. We buttressed the fund for
higher interest rates by maintaining a shorter duration than the benchmark
Lehman Brothers U.S. Aggregate Index. We also attempted to stay defensive in our
short-term holdings. This latter positioning proved more beneficial to
performance than our overall rate outlook because longer-term interest rates
declined.

Yields will vary and are not guaranteed.

For the past six months, the portfolio held a sizable allocation of its
corporate holdings in floating-rate notes. This gave us credit exposure and
higher yields but minimized our overall interest rate exposure. In addition, we
owned a modest position in dividend-paying stocks in several high-quality
sectors such as integrated oils and financials that allowed the fund to generate
additional income. This also helped broaden diversification and generate capital
appreciation while mitigating a measure of interest rate risk. Investors became
more interested in higher-yielding corporate bonds as they grew less concerned
about corporate governance and balance sheet leverage. Many of our lower-quality
issues, particularly those that experienced severe distress last year, performed
well.

<PAGE>

Owning fixed-rate securities that pay higher yields than Treasuries cushioned
the impact of Fed tightening. Many residential and commercial mortgage-backed,
asset-backed, and corporate bonds also generated good gains over the six-month
period. Nondollar bonds also contributed to results, thanks to a weaker dollar,
and in most cases, they paid substantially higher yields than U.S. Treasuries.
Unlike the U.S., many overseas governments have fiscal and monetary policies
that are supportive of steady or declining interest rates.

Strengthening economic fundamentals supported our commitment to higher-yielding
sectors. Throughout the period, we added to mortgage-backed issues (40% of net
assets). Our commitment to the commercial mortgage-backed market and
asset-backed securities provided a steady source of income and cash flow
stability. However, we trimmed our already underweight position in agency
holdings because valuations are high and regulatory uncertainty increases risk
in the sector.

Strong investor demand for additional yield and higher headline inflation
boosted the performance of Treasury inflation-protected securities. Maintaining
a modest allocation to TIPS proved beneficial during the period. Steadily
improving credit trends and stronger

<PAGE>

economic growth led us to attractively priced corporate bonds in the natural
gas, cable and media, and energy sectors. The fund maintained its significant
overweight in BBB rated corporate bonds because supply remains low while foreign
demand is strong.

OUTLOOK

The steady, resource-absorbing pace of job gains should provide further support
to a fundamentally healthy economy. In such an environment, we expect the
Federal Reserve to continue its slow march toward higher short-term rates
through 2005. Increases in long-term rates should be muted as long as core
inflation remains contained.

Several issues, however, could potentially disrupt this benign outlook. Bulging
imbalances created by the U.S. budget and trade deficits are worrisome,
especially with the prospect of a weaker dollar. Foreign investors, especially
Asian central banks, have been active participants in the investment-grade
markets over the past several years. Their support of the U.S. bond market has
clearly contributed to a relatively stable interest rate environment. Though it
is not our base case, a dramatic shift in asset preferences away from the U.S.
dollar would clearly be a negative across the yield curve.

Current valuations also concern us. Both corporate and mortgage yield spreads
(the difference between Treasury yields and other similar-maturity bonds) leave
little room for a negative market event, such as more aggressive Fed tightening.
Although credit fundamentals remain strong and mortgage prepayment volatility is
low, we believe the possibility of significant spread compression from current
levels is remote. We will be more selective in these sectors going forward.

Our research team continues to seek opportunities wherever they present
themselves. For example, many foreign investment-grade government bonds offer
higher yields than comparable-maturity U.S. Treasuries. We believe that
tax-exempt bonds also offer tactical opportunities for us, as do longer-term
TIPS. As always, we strive to enhance returns while managing risk by investing
in securities that hold what we believe are

favorable total return characteristics. We appreciate your continued confidence
in this endeavor.

RISKS OF BOND INVESTING

Bonds are subject to interest rate risk, the decline in bond prices that usually
accompanies a rise in interest rates, and credit risk, the chance that any fund
holding could have its credit rating downgraded or that a bond issuer will
default (fail to make timely payments of interest or principal), potentially
reducing the fund's income level and share price. Mortgage-backed securities are
subject to prepayment risk, particularly if falling rates lead to heavy
refinancing activity, and extension risk, which is an increase in interest rates
that causes a fund's average maturity to lengthen unexpectedly due to a drop in
mortgage prepayments. This could increase the fund's sensitivity to rising
interest rates and its potential for price declines.

GLOSSARY

CS First Boston High Yield Index: An index that tracks the performance of
domestic noninvestment-grade corporate bonds.

Duration: A measure of a bond or bond fund's sensitivity to changes in interest
rates. For example, a fund with a four-year duration would fall about 4% in
response to a one-percentage-point rise in interest rates, and vice versa.

Federal funds rate: The interest rate charged on overnight loans of reserves by
one financial institution to another in the United States. The Federal Reserve
sets a target federal funds rate to affect the direction of interest rates.

Lehman Brothers Mortgage-Backed Securities Index: An unmanaged index of 15- and
30-year fixed-rate securities backed by GNMA.

Lehman Brothers U.S. Aggregate Index: An unmanaged index that tracks the
performance of investment-grade government and corporate bonds. This index is
widely accepted as the benchmark for the broad U.S. investment-grade bond
market.

Lehman Brothers U.S. Credit Index: (Formerly the U.S. Corporate Investment Grade
Index) An unmanaged index that tracks the performance of investment-grade
corporate bonds.

Lehman Brothers U.S. Treasury Index: An unmanaged index of publicly traded
obligations of the U.S. Treasury.

Lipper averages: The averages of all mutual funds in a particular category as
tracked by Lipper Inc.

Weighted average maturity: The weighted average of the stated maturity dates of
a portfolio's securities. In general, the longer the average maturity, the
greater the fund's sensitivity to interest rate changes. A shorter average
maturity usually means less interest rate sensitivity and therefore a less
volatile portfolio.

FUND EXPENSE EXAMPLE
--------------------------------------------------------------------------------

As a mutual fund shareholder, you may incur two types of costs: (1) transaction
costs such as redemption fees or sales loads and (2) ongoing costs, including
management fees, distribution and service (12b-1) fees, and other fund expenses.
The following example is intended to help you understand your ongoing costs (in
dollars) of investing in the fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 invested at the beginning of the most recent six-month period and held
for the entire period.

Please note that the fund has three share classes: The original share class
("investor class") charges no distribution and service (12b-1) fee; Advisor
Class shares are offered only through unaffiliated brokers and other financial
intermediaries and charge a 0.25% 12b-1 fee; R Class shares are available to
retirement plans serviced by intermediaries and charge a 0.50% 12b-1 fee. Each
share class is presented separately in the table.

Actual Expenses
The first line of the following table ("Actual") provides information about
actual account values and expenses based on the fund's actual returns. You may
use the information in this line, together with your account balance, to
estimate the expenses that you paid over the period. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number in the first line under the heading
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

Hypothetical Example for Comparison Purposes
The information on the second line of the table ("Hypothetical") is based on
hypothetical account values and expenses derived from the fund's actual expense
ratio and an assumed 5% per year rate of return before expenses (not the fund's
actual return). You may compare the ongoing costs of investing in the fund with
other funds by contrasting this 5% hypothetical example and the 5% hypothetical
examples that appear in the shareholder reports of the other funds. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period.

Note: T. Rowe Price charges an annual small-account maintenance fee of $10,
generally for accounts with less than $2,000 ($500 for UGMA/UTMA). The fee is
waived for any investor whose T. Rowe Price mutual fund accounts total $25,000
or more, accounts employing automatic investing, and IRAs and other retirement
plan accounts that utilize a prototype plan sponsored by T. Rowe Price (although
a separate custodial or administrative fee may apply to such accounts). This fee
is not included in the accompanying table. If you are subject to the fee, keep
it in mind when you are estimating the ongoing expenses of investing in the fund
and when comparing the expenses of this fund with other funds.

You should also be aware that the expenses shown in the table highlight only
your ongoing costs and do not reflect any transaction costs, such as redemption
fees or sales loads. Therefore, the second line of the table is useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. To the extent a fund charges transaction costs,
however, the total cost of owning that fund is higher.

Current performance may be lower or higher than the quoted past performance,
which cannot guarantee future results. Share price, principal value, and return
will vary, and you may have a gain or loss when you sell your shares. For the
most recent month-end performance information, please visit our Web site
(troweprice.com) or contact a T. Rowe Price representative at 1-800-225-5132.

This table provides returns through the most recent calendar quarter-end rather
than through the end of the fund's fiscal period. It shows how each class would
have performed each year if its actual (or cumulative) returns for the periods
shown had been earned at a constant rate. The T. Rowe Price New Income
Fund-Advisor Class and the T. Rowe Price New Income Fund-R Class began
operations on September 30, 2002. Each shares the portfolio of the existing
retail fund (the original share class of the fund is referred to as the
"investor class"). The average annual total return figures for the Advisor and R
Class have been calculated using the performance data of the investor class up
to the inception date of the class and the actual performance results of the
class since that date. The performance results of the investor class have not
been adjusted to reflect the 12b-1 fee associated with either the Advisor Class
(0.25%) or the R Class (0.50%). Had these fees been included, the performance of
the Advisor and R Classes would have been lower.

Average annual total return figures include changes in principal value,
reinvested dividends, and capital gain distributions. Returns do not reflect
taxes that the shareholder may pay on portfolio distributions or the redemption
of portfolio shares. When assessing performance, investors should consider both
short- and long-term returns.

Unaudited                                                      November 30, 2004

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

T. Rowe Price New Income Fund, Inc. (the fund) is registered under the
Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end
management investment company. The fund seeks the highest level of income
consistent with the preservation of capital over time by investing primarily in
marketable debt securities. The fund has three classes of shares: the New Income
Fund original share class, referred to in this report as the Investor Class,
offered since August 31, 1973, New Income Fund--Advisor Class (Advisor Class),
offered since September 30, 2002, and New Income Fund--R Class (R Class),
offered since September 30, 2002. Advisor Class shares are sold only through
unaffiliated brokers and other unaffiliated financial intermediaries, and R
Class shares are available to retirement plans serviced by intermediaries. The
Advisor Class and R Class each operate under separate Board-approved Rule 12b-1
plans, pursuant to which each class compensates financial intermediaries for
distribution, shareholder servicing, and/or certain administrative services.
Each class has exclusive voting rights on matters related solely to that class,
separate voting rights on matters that relate to all classes, and, in all other
respects, the same rights and obligations as the other classes.

The accompanying financial statements were prepared in accordance with
accounting principles generally accepted in the United States of America, which
require the use of estimates made by fund management.

Valuation
The fund values its investments and computes its net asset value per share at
the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day
that the NYSE is open for business. Debt securities are generally traded in the
over-the-counter market. Securities with original maturities of one year or more
are valued at prices furnished by dealers who make markets in such securities or
by an independent pricing service, which considers yield or price of bonds of
comparable quality, coupon, maturity, and type, as well as prices quoted by
dealers who make markets in such securities. Securities with original maturities
of less than one year are stated at fair value, which is determined by using a
matrix system that establishes a value for each security based on bid-side money
market yields.

Equity securities listed or regularly traded on a securities exchange or in the
over-the-counter market are valued at the last quoted sale price or, for certain
markets, the official closing price at the time the valuations are made, except
for OTC Bulletin Board securities, which are valued at the mean of the latest
bid and

<PAGE>

asked prices. A security that is listed or traded on more than one exchange is
valued at the quotation on the exchange determined to be the primary market for
such security. Listed securities not traded on a particular day are valued at
the mean of the latest bid and asked prices for domestic securities and the last
quoted sale price for international securities.

Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation. Options on futures contracts are valued
at the last sale price. Financial futures contracts are valued at closing
settlement prices. Swap agreements are valued at prices furnished by dealers who
make markets in such securities.

Other investments and those for which the above valuation procedures are
inappropriate or are deemed not to reflect fair value are stated at fair value
as determined in good faith by the T. Rowe Price Valuation Committee,
established by the fund's Board of Directors. In the course of making a good
faith determination of a security's fair value, the fund reviews a variety of
factors, including market and trading trends and the value of comparable
securities, such as unrestricted securities of the same issuer.

Most foreign markets close before the close of trading on the NYSE. If the fund
determines that developments between the close of a foreign market and the close
of the NYSE will, in its judgment, materially affect the value of some or all of
its portfolio securities, which in turn will affect the fund's share price, the
fund will adjust the previous closing prices to reflect the fair value of the
securities as of the close of the NYSE, as determined in good faith by the T.
Rowe Price Valuation Committee, established by the fund's Board of Directors. A
fund may also fair value securities in other situations, such as when a
particular foreign market is closed but the fund is open. In deciding whether to
make fair value adjustments, the fund reviews a variety of factors, including
developments in foreign markets, the performance of U.S. securities markets, and
the performance of instruments trading in U. S. markets that represent foreign
securities and baskets of foreign securities. The fund uses outside pricing
services to provide it with closing market prices and information used for
adjusting those prices. The fund cannot predict how often it will use closing
prices and how often it will adjust those prices. As a means of evaluating its
fair value process, the fund routinely compares closing market prices, the next
day's opening prices in the same markets, and adjusted prices.

Currency Translation
Assets, including investments, and liabilities denominated in foreign currencies
are translated into U.S. dollar values each day at the prevailing

<PAGE>

exchange rate, using the mean of the bid and asked prices of such currencies
against U.S. dollars as quoted by a major bank. Purchases and sales of
securities, income, and expenses are translated into U.S. dollars at the
prevailing exchange rate on the date of the transaction. The effect of changes
in foreign currency exchange rates on realized and unrealized security gains and
losses is reflected as a component of security gains and losses.

Class Accounting
The Advisor Class and R Class each pay distribution, shareholder servicing,
and/or certain administrative expenses in the form of Rule 12b-1 fees, in an
amount not exceeding 0.25% and 0.50%, respectively, of the class's average daily
net assets. Shareholder servicing, prospectus, and shareholder report expenses
incurred by each class are charged directly to the class to which they relate.
Expenses common to all classes and investment income are allocated to the
classes based upon the relative daily net assets of each class's settled shares;
realized and unrealized gains and losses are allocated based upon the relative
daily net assets of each class's outstanding shares.

Investment Transactions, Investment Income, and Distributions
Income and expenses are recorded on the accrual basis. Premiums and discounts on
debt securities are amortized for financial reporting purposes. Inflation
adjustments to the principal amount of inflation-indexed bonds are included in
interest income. Dividends received from mutual fund investments are reflected
as dividend income; capital gain distributions are reflected as realized
gain/loss. Dividend income and capital gain distributions are recorded on the
ex-dividend date. Investment transactions are accounted for on the trade date.
Realized gains and losses are reported on the identified cost basis. Payments
("variation margin") made or received to settle the daily fluctuations in the
value of futures contracts are recorded as unrealized gains or losses until the
contracts are closed. Unsettled variation margin on futures contracts is
included in investments in securities, and unrealized gains and losses on
futures contracts are included in the change in net unrealized gain or loss in
the accompanying financial statements. Unrealized gains and losses on forward
currency exchange contracts are included in investments in securities, and in
the change in net unrealized gain or loss in the accompanying financial
statements. Net periodic receipts or payments required by swap agreements are
accrued daily and recorded as realized gain or loss on securities in the
accompanying financial statements. Fluctuations in the fair value of swap
agreements are recorded in the change in net unrealized gain or loss on
securities in the accompanying financial statements and are reclassified to
realized gain or loss on securities upon termination prior to maturity.
Distributions to shareholders are recorded on the ex-dividend date. Income
distributions are declared by each class on a

<PAGE>

daily basis and paid monthly. Capital gain distributions, if any, are declared
and paid by the fund, typically on an annual basis.

Other
In the normal course of business, the fund enters into contracts that provide
general indemnifications. The fund's maximum exposure under these arrangements
is dependent on claims that may be made against the fund in the future and,
therefore, cannot be estimated; however, based on experience, the risk of
material loss from such claims is considered remote.

NOTE 2 - INVESTMENT TRANSACTIONS

Consistent with its investment objective, the fund engages in the following
practices to manage exposure to certain risks or enhance performance. The
investment objective, policies, program, and risk factors of the fund are
described more fully in the fund's prospectus and Statement of Additional
Information.

Restricted Securities
The fund may invest in securities that are subject to legal or contractual
restrictions on resale. Although certain of these securities may be readily
sold, for example, under Rule 144A, others may be illiquid, and their sale may
involve substantial delays and additional costs, and prompt sale at an
acceptable price may be difficult.

Forward Currency Exchange Contracts
During the six months ended November 30, 2004, the fund was a party to forward
currency exchange contracts under which it is obligated to exchange currencies
at specified future dates and exchange rates. Risks arise from the possible
inability of counterparties to meet the terms of their agreements and from
movements in currency values.

Futures Contracts
During the six months ended November 30, 2004, the fund was a party to futures
contracts, which provide for the future sale by one party and purchase by
another of a specified amount of a specific financial instrument at an agreed
upon price, date, time, and place. Risks arise from possible illiquidity of the
futures market and from movements in security values and/or interest rates.

Options
Call and put options on futures contracts give the holder the right to purchase
or sell, respectively, a particular futures contract at a specified price on a
certain date. Risks arise from possible illiquidity of the options market and
from movements in underlying futures prices. Transactions in options written and
related premiums received during the six months ended November 30, 2004, were as
follows:

                                                  ------------------------------

Swap Agreements
During the six months ended November 30, 2004, the fund was a party to interest
rate swap agreements under which it is obligated to exchange cash flows based on
the difference between specified interest rates applied to a notional principal
amount for a specified period of time. Risks arise from the possible inability
of counterparties to meet the terms of their agreements and from movements in
interest rates.

Securities Lending
The fund lends its securities to approved brokers to earn additional income. It
receives as collateral cash and U.S. government securities valued at 102% to
105% of the value of the securities on loan. Cash collateral is invested in a
money market pooled trust managed by the fund's lending agent in accordance with
investment guidelines approved by fund management. Collateral is maintained over
the life of the loan in an amount not less than the value of loaned securities,
as determined at the close of fund business each day; any additional collateral
required due to changes in security values is delivered to the fund the next
business day. Although risk is mitigated by the collateral, the fund could
experience a delay in recovering its securities and a possible loss of income or
value if the borrower fails to return the securities. Securities lending revenue
recognized by the fund consists of earnings on invested collateral and borrowing
fees, net of any rebates to the borrower and compensation to the lending agent.
At November 30, 2004, the value of loaned securities was $468,570,000; aggregate
collateral consisted of $453,183,000 in the money market pooled trust and U.S.
government securities valued at $29,584,000.

Other
Purchases and sales of portfolio securities, other than short-term and U.S.
government securities, aggregated $368,480,000 and $406,948,000, respectively,
for the six months ended November 30, 2004. Purchases and sales of U.S.
government securities aggregated $1,792,806,000 and $1,500,120,000,
respectively, for the six months ended November 30, 2004.
<PAGE>

NOTE 3 - FEDERAL INCOME TAXES

No provision for federal income taxes is required since the fund intends to
continue to qualify as a regulated investment company under Subchapter M of the
Internal Revenue Code and distribute to shareholders all of its taxable income
and gains. Federal income tax regulations differ from generally accepted
accounting principles; therefore, distributions determined in accordance with
tax regulations may differ in amount or character from net investment income and
realized gains for financial reporting purposes. Financial reporting records are
adjusted for permanent book/tax differences to reflect tax character. Financial
records are not adjusted for temporary differences. The amount and character of
tax-basis distributions and composition of net assets are finalized at fiscal
year-end; accordingly, tax-basis balances have not been determined as of
November 30, 2004.

The fund intends to retain realized gains to the extent of available capital
loss carryforwards. As of May 31, 2004, the fund had $22,720,000 of unused
capital loss carryforwards that expire in fiscal 2009

At November 30, 2004, the cost of investments for federal income tax purposes
was $3,244,260,000. Net unrealized gain aggregated $52,387,000 at period-end, of
which $97,860,000 related to appreciated investments and $45,473,000 related to
depreciated investments.

NOTE 4 - RELATED PARTY TRANSACTIONS

The fund is managed by T. Rowe Price Associates, Inc. (the manager or Price
Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. The
investment management agreement between the fund and the manager provides for an
annual investment management fee, which is computed daily and paid monthly. The
fee consists of an individual fund fee, equal to 0.15% of the fund's average
daily net assets, and the fund's pro-rata share of a group fee. The group fee is
calculated based on the combined net assets of certain mutual funds sponsored by
Price Associates (the group) applied to a graduated fee schedule, with rates
ranging from 0.48% for the first $1 billion of assets to 0.295% for assets in
excess of $120 billion. The fund's portion of the group fee is determined by the
ratio of its average daily net assets to those of the group. At November 30,
2004, the effective annual group fee rate was 0.31%, and investment management
fee payable totaled $1,053,000.

The Advisor Class and R Class are also subject to a contractual expense
limitation through the limitation dates indicated in the table below. During the
limitation

<PAGE>

period, the manager is required to waive its management fee and reimburse a
class for any expenses, excluding interest, taxes, brokerage commissions, and
extraordinary expenses, that would otherwise cause the class's ratio of total
expenses to average net assets (expense ratio) to exceed its expense limitation.
Through the repayment date, each class is required to repay the manager for
expenses previously reimbursed and management fees waived to the extent the
class's net assets have grown or expenses have declined sufficiently to allow
repayment without causing the class's expense ratio to exceed its expense
limitation.

Pursuant to this agreement, at November 30, 2004, management fees waived remain
subject to repayment in the following amounts: $10,000 through September 30,
2006 and $1,000 through September 30, 2008.

In addition, the fund has entered into service agreements with Price Associates
and two wholly owned subsidiaries of Price Associates (collectively, Price).
Price Associates computes the daily share prices and maintains the financial
records of the fund. T. Rowe Price Services, Inc., provides shareholder and
administrative services in its capacity as the fund's transfer and dividend
disbursing agent. T. Rowe Price Retirement Plan Services, Inc., provides
subaccounting and recordkeeping services for certain retirement accounts
invested in the Investor Class and R Class. For the six months ended November
30, 2004, expenses incurred pursuant to these service agreements were $72,000
for Price Associates, $348,000 for T. Rowe Price Services, Inc., and $611,000
for T. Rowe Price Retirement Plan Services, Inc. At period-end, a total of
$205,000 of these expenses was payable.

Additionally, the fund is one of several mutual funds in which certain college
savings plans managed by Price Associates may invest. As approved by the fund's
Board of Directors, shareholder servicing costs associated with each college
savings plan are borne by the fund in proportion to the average daily value of
its shares owned by the college savings plan. For the six months ended November
30, 2004, the fund was charged $2,000 for shareholder servicing costs related to
the college savings plans, of which $1,000 was for services provided by Price
and $0 was payable at period-end. At November 30, 2004, no shares of the
Investor Class were held by college savings plans.

The fund is also one of several mutual funds sponsored by Price Associates
(underlying Price funds) in which the T. Rowe Price Spectrum Funds (Spectrum
Funds) and T. Rowe Price Retirement Funds (Retirement Funds) may invest. Neither
the Spectrum Funds nor the Retirement Funds invest in the underlying Price funds
for the purpose of exercising management or control. Pursuant to separate,
special servicing agreements, expenses associated with the operation of the
Spectrum and Retirement Funds are borne by each underlying Price fund to the
extent of estimated savings to it and in proportion to the average daily value
of its shares owned by the Spectrum and Retirement Funds, respectively. Expenses
allocated under these agreements are reflected as shareholder servicing expenses
in the accompanying financial statements. For the six months ended November 30,
2004, the fund was allocated $911,000 of Spectrum Funds' expenses and $484,000
of Retirement Funds' expenses. Of these amounts, $900,000 related to services
provided by Price and $223,000 was payable at period-end. At November 30, 2004,
approximately 35.3% of the outstanding shares of the Investor Class were held by
the Spectrum Funds and 12.5% were held by the Retirement Funds.

The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe
Price Government Reserve Investment Fund (collectively, the Reserve Funds),
open-end management investment companies managed by Price Associates and
affiliates of the fund. The Reserve Funds are offered as cash management options
to mutual funds, trusts, and other accounts managed by Price Associates and/or
its affiliates, and are not available for direct purchase by members of the
public. The Reserve Funds pay no investment management fees. During the six
months ended November 30, 2004, dividend income from the Reserve Funds totaled
$1,660,000, and the value of shares of the Reserve Funds held at November 30,
2004 and May 31, 2004 was $172,102,000 and $238,642,000, respectively.

As of November 30, 2004, T. Rowe Price Group, Inc. and/or its wholly owned
subsidiaries owned 12,226 shares of the Advisor Class, aggregating less than 1%
of the fund's net assets.
