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: New Income
Fund (New Income 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 brokers and other 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 and
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 official
closing price for certain markets, at the time the valuations are made. 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 ask 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. Purchased and written options on
futures contracts are valued at the last sale price. Financial futures contracts
are valued at closing settlement prices.

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.

Most foreign markets close before the NYSE. Normally, developments that could
affect the values of securities that occur between the close of a foreign market
and the close of the NYSE will not be reflected in security valuations used by
the fund to compute its share price. However, if developments are so significant
that they will, in the judgment of the fund, clearly and materially affect
security values, such valuations may be adjusted to reflect the estimated 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.

Currency Translation
Assets, including investments, and liabilities denominated in foreign currencies
are translated into U.S. dollar values each day at the prevailing exchange rate,
using the mean of the bid and ask 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 and 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. Income distributions are declared by each class on a daily
basis and paid monthly. Capital gain distributions, if any, are declared and
paid by the fund, typically on an annual basis.

Expenses Paid Indirectly
Credits earned on temporarily uninvested cash balances at the custodian are used
to reduce the fund's custody charges. Custody expense in the accompanying
statement of operations is presented before reduction for credits, which totaled
$22,000 for the six months ended November 30, 2003.

Other
Income and expenses are recorded on the accrual basis. Investment
transactions are accounted for on the trade date. Realized gains and losses are
reported on the identified cost basis. Premiums and discounts on municipal and
debt securities are amortized for financial reporting purposes. Dividend income
and distributions to shareholders are recorded by the fund on the ex-dividend
date. Dividends from mutual fund investments are reflected as dividend income;
capital gain distributions from mutual fund investments are reflected as
realized gain/loss. Payments ("variation margin") made or received by the fund
to settle the daily fluctuations in the value of futures contracts are recorded
as unrealized gains or losses until the contracts are closed. Unrealized gains
and losses on futures and forward currency exchange contracts are included in
Other assets and Other liabilities, respectively, and in Change in net
unrealized gain or loss in the accompanying financial statements. 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.





Forward Currency Exchange Contracts
During the six months ended November 30, 2003, 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, 2003, 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 until
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, 2003, were as
follows:


                                                 Number of
                                                 Contracts             Premiums

Closed                                                (480)            (503,000)

Outstanding at end of period                            -          $         -
                                                     --------------------------

Swap Agreements
During the six months ended November 30, 2003, 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, 2003, the value of loaned
securities was $306,548,000; aggregate collateral consisted of $264,826,000 in
the money market pooled trust and U.S. government securities valued at
$52,493,000.

Affiliated Companies
The fund may invest in certain securities that are considered affiliated
companies. As defined by the 1940 Act, an affiliated company is one in which the
fund owns 5% or more of the outstanding voting securities. At November 30, 2003,
the fund's investment in the T. Rowe Price Reserve Investment Fund was its only
affiliated holding and represented 11.2% of the value of the fund's investments
in securities.

Other
Purchases and sales of portfolio securities, other than short-term and U.S.
government securities, aggregated $417,889,000 and $365,569,000, respectively,
for the six months ended November 30, 2003. Purchases and sales of U.S.
government securities aggregated $2,199,330,000 and $2,218,934,000,
respectively, for the six months ended November 30, 2003.


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, 2003.

The fund intends to retain realized gains to the extent of available capital
loss carryforwards. As of May 31, 2003, the fund had $39,329,000 of unused
capital loss carryforwards, of which $1,791,000 expire in 2008, and $37,538,000
expire in 2009.

At November 30, 2003, the cost of investments for federal income tax purposes
was $2,662,101,000. Net unrealized gain aggregated $56,496,000 at period-end, of
which $90,637,000 related to appreciated investments and $34,141,000 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,
2003, the effective annual group fee rate was 0.32%, and investment management
fee payable totaled $862,000.

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 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.

- --------------------------------------------------------------------------------
                                             Advisor Class              R Class
Expense Limitation                                    0.90%                1.15%
Limitation Date                                    9/30/04              9/30/04
Repayment Date                                     9/30/06              9/30/06

At November 30, 2003, expenses previously reimbursed by the manager remain
subject to repayment in the amount of $2,000 through September 30, 2006.

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 New Income class and R Class. Expenses incurred pursuant to
these service agreements totaled $1,067,000 for the six months ended November
30, 2003, of which $206,000 was payable at period-end.

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, 2003, the fund was charged $4,000 for shareholder servicing costs related to
the college savings plans, of which $3,000 was for services provided by Price
and $1,000 was payable at period-end. At November 30, 2003, approximately 0.2%
of the outstanding shares of the New Income 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,
2003, the fund was allocated $988,000 of Spectrum Funds' expenses and $95,000 of
Retirement Funds' expenses. Of these amounts, $966,000 related to services
provided by Price and $150,000 was payable at period-end. At November 30, 2003,
approximately 36.0% of the outstanding shares of the New Income class were held
by the Spectrum Funds and 2.3% 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. The
Reserve Funds are offered as cash management options only to mutual funds,
trusts, and other accounts managed by Price Associates and/or its affiliates,
and are not available to the public. The Reserve Funds pay no investment
management fees. During the six months ended November 30, 2003, dividend income
from the Reserve Funds totaled $2,353,000.
