NOTES TO PORTFOLIO OF INVESTMENTS

T. Rowe Price Spectrum Fund, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act) as a nondiversified, open-end management investment company. The Spectrum Growth Fund, Spectrum Income Fund, and Spectrum International Fund (collectively, the Spectrum Funds) are three portfolios established by the corporation.

Each Spectrum Fund diversifies its assets within set limits among specific underlying T. Rowe Price funds (underlying Price funds). Spectrum Growth seeks long-term capital appreciation and growth of income with current income a secondary objective. Spectrum Income seeks a high level of current income with moderate share price fluctuation. Spectrum International seeks long-term capital appreciation.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Basis of Preparation
The accompanying Portfolios of Investments were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), which require the use of estimates made by fund management. Fund management believes that estimates and valuations of the underlying Price funds are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the Portfolios of Investments may differ from the values ultimately realized upon sale of the underlying Price funds.

Investment Transactions
Purchases and sales of the underlying Price funds are accounted for on the trade date.

New Accounting Pronouncement
On January 1, 2010, the Spectrum Funds adopted new accounting guidance that requires enhanced disclosures about fair value measurements in the financial statements. Adoption of this guidance had no impact on the funds’ net assets or results of operations.

NOTE 2 - VALUATION

Each fund’s investments are reported at fair value as defined under GAAP. Each 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. Investments in the underlying Price funds are valued at their closing net asset value per share on the day of valuation. Investments for which these 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 funds’ Board of Directors.

Various inputs are used to determine the value of a fund’s investments. These inputs are summarized in the three broad levels listed below:

Level 1 – quoted prices in active markets for identical securities

Level 2 – observable inputs other than Level 1 quoted prices (including, but not limited to, quoted prices for similar securities, interest rates, prepayment speeds, and credit risk)

Level 3 – unobservable inputs

Observable inputs are those based on market data obtained from sources independent of the fund, and unobservable inputs reflect the fund’s own assumptions based on the best information available. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. On March 31, 2010, all of the investments in underlying Price funds were classified as Level 1, based on the inputs used to determine their values.

NOTE 3 - FEDERAL INCOME TAXES

At March 31, 2010, the cost of investments for federal income tax purposes and net unrealized gain (loss) on investments was as follows:

NOTE 4 - RELATED PARTIES

The Spectrum Funds do not invest in the underlying Price funds for the purpose of exercising management or control; however, investments by the Spectrum Funds may represent a significant portion of an underlying Price fund’s net assets. At March 31, 2010, Spectrum Growth and Spectrum International Funds each held less than 25% of the outstanding shares of any underlying Price fund; Spectrum Income Fund held approximately 53% of the outstanding shares of the Corporate Income Fund and 34% of the GNMA Fund.
