Notes to Financial Statements

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: the High Yield Fund original share class, referred to in this report as the Investor Class, offered since December 31, 1984, and the High Yield Fund–Advisor Class (Advisor Class), offered since March 31, 2000. Advisor Class shares are sold only through unaffiliated brokers and other unaffiliated financial intermediaries that are compensated by the class for distribution, shareholder servicing, and/or 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.

NOTE 1 - SIGNIfIcaNT accOUNTING POLIcIES

Basis of Preparation The fund is an investment company and follows accounting

and reporting guidance in the Financial Accounting Standards Board (FASB)

Accounting Standards Codification Topic 946 (ASC 946). The accompanying

financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), including but not limited to ASC 946. GAAP requires the use of estimates made by management. Management believes that estimates and valuations are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the accompanying financial statements may differ from the value ultimately realized upon sale or maturity.

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. Paydown gains and losses are recorded as an adjustment to 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. Income tax-related interest and penalties, if incurred, would be recorded as income tax expense. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Distributions to shareholders are recorded on the ex-dividend date. Distributions from REITs are initially

recorded as dividend income and, to the extent such represent a return of capital or capital gain for tax purposes, are reclassified when such information becomes available. Income distributions are declared by each class daily and paid monthly. Capital gain distributions, if any, are generally declared and paid by the fund annually.

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 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 pays distribution, shareholder servicing,

and/or certain 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.

Redemption fees A 2% fee is assessed on redemptions of fund shares held

for 90 days or less to deter short-term trading and to protect the interests of long-term shareholders. Redemption fees are withheld from proceeds that shareholders receive from the sale or exchange of fund shares. The fees are paid to the fund and are recorded as an increase to paid-in capital. The fees may cause the redemption price per share to differ from the net asset value per share.

New accounting Guidance In June 2014, FASB issued Accounting Standards

Update (ASU) No. 2014-11, Transfers and Servicing (Topic 860), Repurchase-to- Maturity Transactions, Repurchase Financings, and Disclosures. The ASU changes

the accounting for certain repurchase agreements and expands disclosure requirements related to repurchase agreements, securities lending, repurchase- to-maturity and similar transactions. The ASU is effective for interim and annual reporting periods beginning after December 15, 2014. Adoption will have no effect on the fund’s net assets or results of operations.
