c   T. Rowe Price Associates, Inc. has agreed (through September 30, 2015) to waive its fees and/or bear any expenses (excluding interest, taxes, brokerage, extraordinary expenses, and acquired fund fees) that would cause the fund’s ratio of expenses to average net assets to exceed 0.35%.

Portfolio Turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance.

Investments, Risks, and Performance

Principal Investment Strategies The fund invests in a diversified portfolio of shorter-term investment-grade corporate and government securities, including mortgage-backed securities, money market securities and bank obligations. Normally, the fund will invest at least 80% of its net assets (including any borrowings for investment purposes) in bonds and all of the securities purchased by the fund will be rated investment-grade (AAA, AA, A, BBB, or an equivalent rating) at the time of purchase by at least one of the major credit rating agencies or, if unrated, deemed to be investment-grade quality by T. Rowe Price. While the fund may purchase an individual security with a maturity of up to 5 years, under normal conditions the fund’s dollar-weighted average effective maturity will be 1.5 years or less.

Investment decisions reflect the portfolio manager’s outlook for interest rates and the economy, as well as the prices, yields, and credit quality of various securities in which the fund may invest. For example, if interest rates are expected to fall, the fund may purchase longer-term securities (to the extent consistent with the fund’s investment program) in an attempt to seek higher yields and/or capital appreciation. Conversely, if interest rates are expected to rise, the fund may seek securities with shorter maturities.

The fund may sell holdings for a variety of reasons, such as to adjust the portfolio’s average maturity, duration, or overall credit quality, or to shift assets into and out of higher-yielding or lower-yielding securities or certain sectors.

Principal Risks As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund are summarized as follows:

Active management risk The fund is subject to the risk that the investment adviser’s judgments about the attractiveness, value, or potential appreciation of the fund’s investments may prove to be incorrect. If the securities selected and strategies employed by the fund fail to produce the intended results, the fund could underperform other funds with similar objectives and investment strategies.

Interest rate risk This is the risk that a rise in interest rates will cause the price of a fixed rate debt security to fall. Prices fall because the bonds and notes in the fund’s

Summary	3

portfolio become less attractive to other investors when securities with higher yields become available. Generally, securities with longer maturities and funds with longer weighted average maturities carry greater interest rate risk. During periods of extremely low or negative interest rates, the fund may not be able to maintain a positive yield or yields on par with historical levels.

Credit risk This is the risk that an issuer of a debt security could suffer an adverse change in financial condition that results in a payment default, security downgrade, or inability to meet a financial obligation.

Liquidity risk This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price.

Prepayment risk and extension risk Prepayment risk is the risk that the principal on mortgage-backed securities, other asset-backed securities or any debt security with an embedded call option may be prepaid at any time, which could reduce yield and market value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Extension risk may result from a rise in interest rates, which tends to make mortgage-backed securities, asset-backed securities, and other callable debt securities more volatile.

Performance Because the fund commenced operations in 2012, there is no historical performance information shown here. Performance history will be presented after the fund has been in operation for one full calendar year.
