Improved economic data before the election and hopes for even faster growth under the incoming Trump administration weighed on securities that are vulnerable to rising interest rates, especially Treasury bonds. Over the six-month period, the yield on the two-year U.S. Treasury note rose to 1.11% from 0.87% and the yield curve steepened as longer-term rates rose more than rates on shorter maturities.

The Ultra Short-Term Bond Fund returned 0.82% during the six-month period ended November 30, 2016, compared with 0.37% for the Bloomberg Barclays Short-Term Government/Corporate Index. The Lipper Ultra-Short Obligations Funds Average generated a 0.64% return for the same period. The portfolio’s relative outperformance stemmed mainly from its allocation to floating rate notes. The fund’s net asset value rose to $5.01, and dividends contributed $0.03 per share in the six-month period. The investment objective of the fund is to provide incremental income above that of a money market fund, but with a slightly higher degree of principal risk.

The U.S. economy picked up after sluggish performance in the first half of 2016. Although the pace of employment growth moderated, the labor market tightened and wage growth modestly accelerated.

Inflation pressures firmed, too, as commodity prices rebounded above their early-2016 lows. During the six-month period, interest rates moved higher, as markets anticipated that the Federal Reserve would raise its federal funds target rate in late 2016. That upward rate move accelerated after the U.S. election as inflation expectations increased immediately following our reporting period and the central bank lifted the fed funds target rate range to 0.50% to 0.75%—an increase of 25 basis points (one hundred basis points equal one percentage point). The yield curve steepened as long-term rates increased more than short-maturity yields. The yield on the two-year Treasury note began the period at 0.87% and rose to 1.11%. (Bond prices and yields move in opposite directions.) Credit spreads on investment-grade corporate bonds narrowed significantly over the period, especially as Treasury yields rose after the election. Strong demand from yield-hungry investors (particularly those in Asia) was satiated by new supply. The prospect of corporate tax cuts and higher levels of government spending from the Trump administration helped support investment-grade corporate bonds as did a decline in risk aversion following the stabilization in oil prices.

While a slow move to higher rates was expected, the sharp move higher that we saw in November was not. Still, the fund’s gradual shift over the period to a more defensive duration posture, our focus on building a cash position, and an emphasis on adding floating rate notes to the portfolio all proved beneficial to performance. In particular, the fund’s exposure to floating rate notes—approximately 20% of the portfolio—benefited from a sharp move higher in the LIBOR. The LIBOR increase was the result of asset reallocations occurring in the money markets as a result of money fund reform, which took effect in October. With about 40% of the portfolio maturing in one year or less, the fund’s net asset value was somewhat protected from the interest rate shifts we have seen.

The fund’s securitized positions continued to perform well. These bonds are generally the most senior tranches—the first lien on the assets of an asset pool, which are generally considered safer investments—backed by receivables, leases, commercial and residential mortgages, and auto loans. Their high credit quality (AAA and AA) and rapid self-amortizing features (i.e., their payments consist of both principal and interest), such that the loan will be paid off at the end of a scheduled term, along with decent yields, have made them a significant part of the portfolio. Top performers in the securitized sector included debt issued by SMB Private Education Loan Trust, Synchrony Credit Card Master Note Trust, and Suntrust Auto Receivables Trust. (Please refer to the fund’s portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.)

Corporate bonds make up the bulk of the fund. We have been finding good value in lower-rated energy, mid-stream, and utility names—especially as uncertain oil prices have improved valuations on the bonds. Our Murphy Oil holdings were the fund’s top contributor as they benefited from the stabilization in oil prices. Money center banks continued to be large issuers of debt, and this sector remained a significant overweight in the portfolio. Many of our bank holdings are floating rate issues that we expect will benefit as rates move higher over the next two years.

While we are primarily a cash bond manager, we occasionally employ the limited use of derivatives in our strategy for hedging purposes. Derivatives may include futures, options, and interest-only mortgages, as well as credit default and interest rate swaps. Given our expectations that rates would move higher before a Fed tightening in December, we reduced the overall duration of the portfolio by actively shorting some derivatives, including U.S. Treasury two- and five-year note futures, fed funds futures, and eurodollar futures. We expect to reduce our derivative exposure gradually, following the actual tightening.

Following the Fed’s December 2016 rate hike, we expect the central bank to carefully weigh the policy actions of the new government as well as global market events before moving forward with any additional rate increases. Much uncertainty remains as we move into 2017. As such, we think it is appropriate to maintain a defensive posture as we begin the new year.

As always, we believe the fund offers a good alternative for cash investors seeking more return than a money market fund as well as a safe haven for equity and bond investors in an uncertain risk environment.

President and chairman of the fund’s Investment Advisory Committee

The committee chairman has day-to-day responsibility for managing the portfolio and works with committee members in developing and executing the fund’s investment program.

Bonds are subject to interest rate risk (the decline in bond prices that usually accompanies a rise in interest rates) and credit risk (the chance that any fund holding could have its credit rating downgraded or that a bond issuer will default by failing to make timely payments of interest or principal), potentially reducing the fund’s income level and share price. Mortgage-backed securities are subject to prepayment risk, particularly if falling rates lead to heavy refinancing activity, and extension risk, which is an increase in interest rates that causes a fund’s average maturity to lengthen unexpectedly due to a drop in mortgage prepayments. This could increase the fund’s sensitivity to rising interest rates and its potential for price declines.

Bloomberg Barclays Short-Term Government/Credit Bond Index: The index measures the performance of short-term government and corporate bonds.

Duration: A measure of a bond fund’s sensitivity to changes in interest rates. For example, a fund with duration of two years would fall about 2% in price in response to a one-percentage-point rise in interest rates, and vice versa.

Federal funds rate: The interest rate charged on overnight loans of reserves by one financial institution to another in the United States. The Federal Reserve sets a target federal funds rate to affect the direction of interest rates.

Lipper averages: The averages of available mutual fund performance returns for specified time periods in defined categories as tracked by Lipper Inc.

LIBOR: The London Interbank Offered Rate, which is a benchmark for short-term taxable rates.

SEC yield (30-day): A method of calculating a fund’s yield that assumes all portfolio securities are held until maturity. Yield will vary and is not guaranteed.

Weighted average effective duration: A measure of a fund’s price sensitivity to changes in interest rates. Funds with longer weighted average effective durations are more sensitive to changes in interest rates than securities of shorter durations.

Weighted average maturity: A measure of a fund’s interest rate sensitivity. In general, the longer the average maturity, the greater the fund’s sensitivity to interest rate changes. The weighted average maturity may take into account the interest rate readjustment dates for certain securities. Money funds must maintain a weighted average maturity of less than 60 days.

Yield curve: A graphic depiction of the relationship between yields and maturity dates for a set of similar securities. A security with a longer maturity usually has a higher yield. If a short-term security offers a higher yield, then the curve is said to be “inverted.” If short- and long-term bonds are offering equivalent yields, then the curve is said to be “flat.”

This chart shows the value of a hypothetical $10,000 investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records). The result is compared with benchmarks, which may include a broad-based market index and a peer group average or index. Market indexes do not include expenses, which are deducted from fund returns as well as mutual fund averages and indexes.

As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs, such as redemption fees or sales loads, and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period.

Actual Expenses
The first line of the following table (Actual) provides information about actual account values and expenses based on the fund’s actual returns. You may use the information on this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes
The information on the second line of the table (Hypothetical) is based on hypothetical account values and expenses derived from the fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund’s actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Note: T. Rowe Price charges an annual account service fee of $20, generally for accounts with less than $10,000. The fee is waived for any investor whose T. Rowe Price mutual fund accounts total $50,000 or more; accounts electing to receive electronic delivery of account statements, transaction confirmations, prospectuses, and shareholder reports; or accounts of an investor who is a T. Rowe Price Preferred Services, Personal Services, or Enhanced Personal Services client (enrollment in these programs generally requires T. Rowe Price assets of at least $100,000). This fee is not included in the accompanying table. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds.

You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher.

T. Rowe Price Short-Term Bond Fund, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The Ultra Short-Term Bond Fund (the fund) is a diversified, open-end management investment company established by the corporation. The fund seeks a high level of income consistent with minimal fluctuation in principal value and liquidity.

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. Income distributions are declared daily and paid monthly. Distributions to shareholders are recorded on the ex-dividend date. Capital gain distributions are generally declared and paid by the fund annually.

New Accounting Guidance In October 2016, the Securities and Exchange Commission (SEC) issued a new rule, Investment Company Reporting Modernization, which, among other provisions, amends Regulation S-X to require standardized, enhanced disclosures, particularly related to derivatives, in investment company financial statements. Compliance with the guidance is required for financial statements filed with the SEC on or after August 1, 2017; adoption will have no effect on the fund’s net assets or results of operations.

The fund’s financial instruments are valued and its net asset value (NAV) per share is computed at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day the NYSE is open for business. However, the NAV per share may be calculated at a time other than the normal close of the NYSE if trading on the NYSE is restricted, if the NYSE closes earlier, or as may be permitted by the SEC.

Fair Value The fund’s financial instruments are reported at fair value, which GAAP defines as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The T. Rowe Price Valuation Committee (the Valuation Committee) is an internal committee that has been delegated certain responsibilities by the fund’s Board of Directors (the Board) to ensure that financial instruments are appropriately priced at fair value in accordance with GAAP and the 1940 Act. Subject to oversight by the Board, the Valuation Committee develops and oversees pricing-related policies and procedures and approves all fair value determinations. Specifically, the Valuation Committee establishes procedures to value securities; determines pricing techniques, sources, and persons eligible to effect fair value pricing actions; oversees the selection, services, and performance of pricing vendors; oversees valuation-related business continuity practices; and provides guidance on internal controls and valuation-related matters. The Valuation Committee reports to the Board and has representation from legal, portfolio management and trading, operations, risk management, and the fund’s treasurer.

Various valuation techniques and inputs are used to determine the fair value of financial instruments. GAAP establishes the following fair value hierarchy that categorizes the inputs used to measure fair value:

Level 1 – quoted prices (unadjusted) in active markets for identical financial instruments that the fund can access at the reporting date

Level 2 – inputs other than Level 1 quoted prices that are observable, either directly or indirectly (including, but not limited to, quoted prices for similar financial instruments in active markets, quoted prices for identical or similar financial instruments in inactive markets, interest rates and yield curves, implied volatilities, and credit spreads)

Observable inputs are developed using market data, such as publicly available information about actual events or transactions, and reflect the assumptions that market participants would use to price the financial instrument. Unobservable inputs are those for which market data are not available and are developed using the best information available about the assumptions that market participants would use to price the financial instrument. GAAP requires valuation techniques to maximize the use of relevant observable inputs and minimize the use of unobservable inputs. When multiple inputs are used to derive fair value, the financial instrument is assigned to the level within the fair value hierarchy based on the lowest-level input that is significant to the fair value of the financial instrument. Input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level but rather the degree of judgment used in determining those values.

Valuation Techniques Debt securities generally are traded in the over-the-counter (OTC) market. Securities with remaining maturities of one year or more at the time of acquisition are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service, which considers the 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 remaining maturities of less than one year at the time of acquisition generally use amortized cost in local currency to approximate fair value. However, if amortized cost is deemed not to reflect fair value or the fund holds a significant amount of such securities with remaining maturities of more than 60 days, the securities are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service. Generally, debt securities are categorized in Level 2 of the fair value hierarchy; however, to the extent the valuations include significant unobservable inputs, the securities would be categorized in Level 3.

Investments in mutual funds are valued at the mutual fund’s closing NAV per share on the day of valuation and are categorized in Level 1 of the fair value hierarchy. Financial futures contracts are valued at closing settlement prices and are categorized in Level 1 of the fair value hierarchy. Assets and liabilities other than financial instruments, including short-term receivables and payables, are carried at cost, or estimated realizable value, if less, which approximates fair value.

Thinly traded financial instruments 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 Valuation Committee. The objective of any fair value pricing determination is to arrive at a price that could reasonably be expected from a current sale. Financial instruments fair valued by the Valuation Committee are primarily private placements, restricted securities, warrants, rights, and other securities that are not publicly traded.

Subject to oversight by the Board, the Valuation Committee regularly makes good faith judgments to establish and adjust the fair valuations of certain securities as events occur and circumstances warrant. For instance, in determining the fair value of troubled or thinly traded debt instruments, the Valuation Committee considers a variety of factors, which may include, but are not limited to, the issuer’s business prospects, its financial standing and performance, recent investment transactions in the issuer, strategic events affecting the company, market liquidity for the issuer, and general economic conditions and events. In consultation with the investment and pricing teams, the Valuation Committee will determine an appropriate valuation technique based on available information, which may include both observable and unobservable inputs. The Valuation Committee typically will afford greatest weight to actual prices in arm’s length transactions, to the extent they represent orderly transactions between market participants, transaction information can be reliably obtained, and prices are deemed representative of fair value. However, the Valuation Committee may also consider other valuation methods such as a discount or premium from market value of a similar, freely traded security of the same issuer; discounted cash flows; yield to maturity; or some combination. Fair value determinations are reviewed on a regular basis and updated as information becomes available, including actual purchase and sale transactions of the issue. Because any fair value determination involves a significant amount of judgment, there is a degree of subjectivity inherent in such pricing decisions, and fair value prices determined by the Valuation Committee could differ from those of other market participants. Depending on the relative significance of unobservable inputs, including the valuation technique(s) used, fair valued securities may be categorized in Level 2 or 3 of the fair value hierarchy.

Valuation Inputs The following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on November 30, 2016:

There were no material transfers between Levels 1 and 2 during the six months ended November 30, 2016.

During the six months ended November 30, 2016, the fund invested in derivative instruments. As defined by GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variable; it requires little or no initial investment and permits or requires net settlement. The fund invests in derivatives only if the expected risks and rewards are consistent with its investment objectives, policies, and overall risk profile, as described in its prospectus and Statement of Additional Information. The fund may use derivatives for a variety of purposes, such as seeking to hedge against declines in principal value, increase yield, invest in an asset with greater efficiency and at a lower cost than is possible through direct investment, or to adjust portfolio duration and credit exposure. The risks associated with the use of derivatives are different from, and potentially much greater than, the risks associated with investing directly in the instruments on which the derivatives are based. The fund at all times maintains sufficient cash reserves, liquid assets, or other SEC-permitted asset types to cover its settlement obligations under open derivative contracts. The fund values its derivatives at fair value and recognizes changes in fair value currently in its results of operations. Accordingly, the fund does not follow hedge accounting, even for derivatives employed as economic hedges. Generally, the fund accounts for its derivatives on a gross basis. It does not offset the fair value of derivative liabilities against the fair value of derivative assets on its financial statements, nor does it offset the fair value of derivative instruments against the right to reclaim or obligation to return collateral.

As of November 30, 2016, the fund held interest rate futures with cumulative unrealized gain of $13,000 and cumulative unrealized loss of $116,000; the value reflected on the accompanying Statement of Assets and Liabilities is the related unsettled variation margin.

Additionally, during the six months ended November 30, 2016, the fund recognized $75,000 of realized gain on Futures and a $87,000 change in unrealized gain/loss on Futures related to its investments in interest rate derivatives; such amounts are included on the accompanying Statement of Operations.

Counterparty Risk and Collateral The fund invests in exchange-traded or centrally cleared derivative contracts, such as futures, exchange-traded options, and centrally cleared swaps. Counterparty risk on such derivatives is minimal because the clearinghouse provides protection against counterparty defaults. For futures and centrally cleared swaps, the fund is required to deposit collateral in an amount specified by the clearinghouse and the clearing firm (margin requirement), and the margin requirement must be maintained over the life of the contract. Each clearinghouse and clearing firm, in its sole discretion, may adjust the margin requirements applicable to the fund.

Collateral may be in the form of cash or debt securities issued by the U.S. government or related agencies. Cash posted by the fund is reflected as cash deposits in the accompanying financial statements and generally is restricted from withdrawal by the fund; securities posted by the fund are so noted in the accompanying Portfolio of Investments; both remain in the fund’s assets. As of November 30, 2016, securities valued at $122,000 had been posted by the fund for exchange-traded and/or centrally cleared derivatives.

Futures Contracts The fund is subject to interest rate risk in the normal course of pursuing its investment objectives and uses futures contracts to help manage such risk. The fund may enter into futures contracts to manage exposure to interest rate and yield curve movements, security prices, foreign currencies, credit quality, and mortgage prepayments; as an efficient means of adjusting exposure to all or part of a target market; to enhance income; as a cash management tool; or to adjust portfolio duration and credit exposure. A futures contract provides for the future sale by one party and purchase by another of a specified amount of a specific underlying financial instrument at an agreed-upon price, date, time, and place. The fund currently invests only in exchange-traded futures, which generally are standardized as to maturity date, underlying financial instrument, and other contract terms. Payments are made or received by the fund each day to settle daily fluctuations in the value of the contract (variation margin), which reflect changes in the value of the underlying financial instrument. Variation margin is recorded as unrealized gain or loss until the contract is closed. The value of a futures contract included in net assets is the amount of unsettled variation margin; net variation margin receivable is reflected as an asset, and net variation margin payable is reflected as a liability on the accompanying Statement of Assets and Liabilities. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in hedged security values and/or interest rates, and potential losses in excess of the fund’s initial investment. During the six months ended November 30, 2016, the volume of the fund’s activity in futures, based on underlying notional amounts, was generally between 11% and 15% of net assets.

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks and/or to 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.

Restricted Securities The fund may invest in securities that are subject to legal or contractual restrictions on resale. Prompt sale of such securities at an acceptable price may be difficult and may involve substantial delays and additional costs.

Mortgage-Backed Securities The fund may invest in mortgage-backed securities (MBS or pass-through certificates) that represent an interest in a pool of specific underlying mortgage loans and entitle the fund to the periodic payments of principal and interest from those mortgages. MBS may be issued by government agencies or corporations, or private issuers. Most MBS issued by government agencies are guaranteed; however, the degree of protection differs based on the issuer. MBS are sensitive to changes in economic conditions that affect the rate of prepayments and defaults on the underlying mortgages; accordingly, the value, income, and related cash flows from MBS may be more volatile than other debt instruments.

Other Purchases and sales of portfolio securities other than short-term and U.S. government securities aggregated $130,237,000 and $103,585,000, respectively, for the six months ended November 30, 2016. Purchases and sales of U.S. government securities aggregated $24,612,000 and $26,684,000, respectively, for the six months ended November 30, 2016.

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. Distributions determined in accordance with federal income 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 but 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 the date of this report.

The fund intends to retain realized gains to the extent of available capital loss carryforwards. Net realized capital losses may be carried forward indefinitely to offset future realized capital gains. As of May 31, 2016, the fund had $388,000 of available capital loss carryforwards.

At November 30, 2016, the cost of investments for federal income tax purposes was $297,966,000. Net unrealized loss aggregated $423,000 at period-end, of which $365,000 related to appreciated investments and $788,000 related to depreciated investments.

The fund is managed by T. Rowe Price Associates, Inc. (Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. (Price Group). The investment management agreement between the fund and Price Associates provides for an annual investment management fee, which is computed daily and paid monthly. The fee consists of an individual fund fee and a group fee. The individual fund fee is equal to 0.01% of the fund’s average daily net assets; prior to November 30, 2016, the individual fund fee had been 0.08%. The group fee rate 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 0.270% for assets in excess of $500 billion. The fund’s group fee is determined by applying the group fee rate to the fund’s average daily net assets. At November 30, 2016, the effective annual group fee rate was 0.29%.

The fund is also subject to a contractual expense limitation through September 30, 2017. During the limitation period, Price Associates is required to waive its management fee and pay the fund for any expenses (excluding interest, expenses related to borrowings, taxes, and brokerage, and other non-recurring expenses permitted by the investment management agreement) that would otherwise cause the fund’s ratio of annualized total expenses to average net assets (expense ratio) to exceed its expense limitation of 0.35%. The fund is required to repay Price Associates for expenses previously waived/paid to the extent its net assets grow or expenses decline sufficiently to allow repayment without causing the fund’s expense ratio to exceed its expense limitation in effect at the time of the waiver. However, no repayment will be made more than three years after the date of a payment or waiver. Pursuant to this agreement, $201,000 of expenses were waived/paid by Price Associates during the six months ended November 30, 2016. Including these amounts, expenses previously waived/paid by Price Associates in the amount of $1,497,000 remain subject to repayment by the fund at November 30, 2016.

In addition, the fund has entered into service agreements with Price Associates and two wholly owned subsidiaries of Price Associates (collectively, Price). Price Associates provides certain accounting and administrative services to 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 fund. For the six months ended November 30, 2016, expenses incurred pursuant to these service agreements were $40,000 for Price Associates; $39,000 for T. Rowe Price Services, Inc.; and less than $1,000 for T. Rowe Price Retirement Plan Services, Inc. The total amount payable at period-end pursuant to these service agreements is reflected as Due to Affiliates in the accompanying financial statements.

The fund may invest in the T. Rowe Price Government Reserve Fund, the T. Rowe Price Treasury Reserve Fund, or the T. Rowe Price Short-Term Fund (collectively, the Price Reserve Funds), open-end management investment companies managed by Price Associates and considered affiliates of the fund. The Price Reserve Funds are offered as short-term investment options to mutual funds, trusts, and other accounts managed by Price Associates or its affiliates and are not available for direct purchase by members of the public. The Price Reserve Funds pay no investment management fees.

As of November 30, 2016, T. Rowe Price Group, Inc., or its wholly owned subsidiaries owned 19,780,902 shares of the fund, representing 33% of the fund’s net assets.

The fund may participate in securities purchase and sale transactions with other funds or accounts advised by Price Associates (cross trades), in accordance with procedures adopted by the fund’s Board and Securities and Exchange Commission rules, which require, among other things, that such purchase and sale cross trades be effected at the independent current market price of the security. During the six months ended November 30, 2016, the fund had no purchases or sales cross trades with other funds or accounts advised by Price Associates.
