NOTES TO FINANCIAL STATEMENTS

Note 1 - Significant Accounting Policies

     T. Rowe Price High Yield 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 high current income and,
     secondarily, capital appreciation. The fund has two classes of shares: High
     Yield Fund (High Yield class), offered since December 31, 1984, and High
     Yield Fund--Advisor Class (Advisor Class), offered since March 31, 2000.
     Advisor Class shares are sold only through brokers and other financial
     intermediaries that are compensated by the class for distribution and
     certain administrative services under a Board-approved Rule 12b-1 plan.
     Each class has exclusive voting rights on matters related solely to that
     class, separate voting rights on matters that relate to both classes, and,
     in all other respects, the same rights and obligations as the other class.

     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.




     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 pays distribution and administrative expenses in the form
     of Rule 12b-1 fees, in an amount not exceeding 0.25% 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 both 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 $55,000 for the six months ended November 30, 2003.

     Redemption Fees
     A 1% fee is assessed on redemptions of fund shares held less than 1 year.
     Such fees are withheld from redemption proceeds and retained by the fund,
     and have the primary effect of increasing paid-in capital.




     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 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. 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.

     Noninvestment-Grade Debt Securities
     At November 30, 2003, approximately 92.6% of the fund's net assets were
     invested in noninvestment-grade debt securities, commonly referred to as
     "high-yield" or "junk" bonds. A real or perceived economic downturn or
     higher interest rates could adversely affect the liquidity or value, or
     both, of such securities because such events could lessen the ability of
     issuers to make principal and interest payments.

     Other
     Purchases and sales of portfolio securities, other than short-term and U.S.
     government securities, aggregated $1,657,968,000 and $1,120,981,000,
     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.

     For tax purposes, the fund has elected to treat net capital losses realized
     between November 1 and May 31 of each year as occurring on the first day of
     the following tax year; consequently, $23,917,000 of realized losses
     recognized for financial reporting purposes in the year ended May 31, 2003
     were recognized for tax purposes on June 1, 2003. Further the fund intends
     to retain realized gains to the extent of available capital loss
     carryforwards. As of May 31, 2003, the fund had $418,658,000 of unused
     capital loss carryforwards, of which $47,671,000 expire in 2004,
     $10,354,000 expire in 2005, and $360,633,000 thereafter through 2011.

     At November 30, 2003, the cost of investments for federal income tax
     purposes was $3,521,733,000. Net unrealized gain aggregated $116,601,000 at
     period-end, of which $210,167,000 related to appreciated investments and
     $93,566,000 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 0.30% 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 $1,835,000.

     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 High
     Yield class. Expenses incurred pursuant to these service agreements totaled
     $673,000 for the six months ended November 30, 2003, of which $99,000 was
     payable at period-end.

     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 $898,000 of Spectrum Funds' expenses and
     $52,000 of Retirement Funds' expenses. Of these amounts, $858,000 related
     to services provided by Price and $156,000 was payable at period-end. At
     November 30, 2003, approximately 25.6% of the outstanding shares of the
     High Yield class were held by the Spectrum Funds and 0.9% 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 $780,000.
