T. ROWE PRICE GLOBAL MULTI-SECTOR BOND FUND

HIGHLIGHTS

■	The Global Multi-Sector Bond Fund outperformed its Lipper peer group average but lagged its market benchmark for the six months ended November 30, 2018.

■	The fund’s currency positioning weighed on relative returns, while our interest rate and country positioning benefited relative performance.

■	The fund is conservatively positioned, with shorter-than-benchmark overall duration and modest exposure to corporate credit.

■	We anticipate that global economic growth rates will converge and that monetary policy will continue to shift toward data dependence, which may increase uncertainty. We believe that we can nimbly position the portfolio to benefit from various market scenarios as conditions evolve.

CIO Market Commentary

Dear Shareholder

Financial markets were challenging for both bond and stock investors in the six months ended November 30, 2018, the first half of your fund’s fiscal year. Longer-term Treasury yields rose through most of the period, providing a general headwind to fixed income returns. The prospect of higher interest rates also weighed on stock prices, and investors faced additional tests from deepening U.S.-China trade tensions, a strengthening U.S. dollar, and signs of slowing global growth.

The weak performance of most asset classes over the past six months stood in stark contrast to solid fundamentals, particularly in the U.S. Thanks in part to recent fiscal stimulus, U.S. gross domestic product expanded at an annualized rate of 4.2% in the second quarter of the year and 3.5% in the third—the best back-to-back performance in four years. Profit growth in the two quarters was even more impressive, with earnings for the S&P 500 as a whole rising at the fastest pace since the recovery from the financial crisis nearly a decade ago.

As usual, the robust economy presented a mixed blessing for bond investors. The strong economic data—including signs that wage gains were finally taking root—fostered a rise in longer-term interest rates and weighed on bond prices. (Bond prices and yields move in opposite directions.) The yield on the benchmark 10-year Treasury note jumped from 2.83% at the end of May to 3.25% in intraday trading on October 5—its highest level since the summer of 2011.

On the positive side, healthy economic conditions also helped solidify borrowers’ balance sheets, bolstering corporate bonds and other credit-sensitive issues. Riskier bonds also typically sport higher coupons, which helped insulate total returns from a decline in bond prices. Indeed, asset-backed securities and better-rated (B and Ba) high yield corporate bonds were among the few fixed income sectors to record gains during the period. Leveraged loans, which feature floating interest rates, were also positive.

Solid economic data paired with tame overall inflation allowed the Federal Reserve to stick to its path of gradually raising short-term interest rates, boosting returns for those seeking current income. The Fed raised the federal funds rate again in June and September and, as of this writing, appears likely to do so again in December. The Fed’s rate increases and the strong U.S. economy attracted assets from overseas, where interest rates in most developed economies generally remained near zero. As a result, most currencies fell against the dollar, weighing on returns for U.S. investors in foreign markets.

The jump in interest rates eventually spilled over into U.S. equity markets, helping push the S&P 500 Index back into its second correction (down over 10% from its highs) for the year in the month of October. Rising trade tensions with China and slowing growth in Europe and Asia also contributed to the turn in sentiment.

In fact, worries about the U.S. economy overheating and sparking inflation dissipated in November, as investors grew more concerned that global growth would slow significantly in 2019. Some late disappointing economic data, along with investors shifting assets from stocks to bonds, caused longer-term bond yields to fall back sharply. In just a few weeks, the yield on the 10-year Treasury note retraced more than half of its advance since May and ended November just above 3%.

While a slowdown in the U.S. economy and corporate profit growth seems all but inevitable in 2019, it seems premature to conclude that the current expansion is coming to an end. Late-cycle markets such as this one tend to create challenges but also dislocations that savvy investors can exploit. You can be confident that your fund’s manager is drawing on the firm’s in-depth research and fundamental analysis in seeking to find opportunities in the coming year.

Thank you for your continued confidence in T. Rowe Price.

Sincerely,

Robert Sharps
Group Chief Investment Officer

Management’s Discussion of Fund Performance

INVESTMENT OBJECTIVE

The fund seeks to provide high income and some capital appreciation.

FUND COMMENTARY

How did the fund perform in the past six months?

The T. Rowe Price Global Multi-Sector Bond Fund returned -0.05% for the six months ended November 30, 2018, underperforming its new benchmark, the Bloomberg Barclays Global Aggregate Bond USD Hedged Index, and its old benchmark, the Bloomberg Barclays Multiverse USD Hedged Index. However, the fund outperformed the Lipper Global Income Funds Average. (Results for Advisor and I Class shares varied slightly, reflecting their different fee structures.Past performance cannot guarantee future results.)

On October 1, 2018, the fund’s benchmark changed to the Bloomberg Barclays Global Aggregate Bond USD Hedged Index from the Bloomberg Barclays Multiverse USD Hedged Index. The new benchmark is more commonly used to track the returns of the global fixed income market. The benchmark change will not impact the management of the fund.

What factors influenced the fund’s performance?

The fund’s overall currency positioning weighed on relative returns. Emerging markets currencies posted steep declines against the U.S. dollar, and the portfolio’s exposure to these currencies was a drag on performance although many currencies recovered some of their losses against the U.S. dollar near the end of the reporting period. Long positions in the Brazilian real, which fell nearly 4%, and the Russian ruble, which declined about 7%, detracted from returns. On the positive side, a short position in the Turkish lira was beneficial as the currency declined more than 13% against the U.S. dollar.

Interest rate and country positioning contributed to the fund’s relative performance but could not offset the drag from currency exposure. Duration exposure in India contributed meaningfully as the short-maturity end of the Indian yield curve rallied after a dislocation resulting from weakness in the Indian rupee and oil and from money market turmoil. (Duration measures a bond’s sensitivity to changes in interest rates.) Also, long-duration positioning in Romania benefited relative returns as Romanian yields decreased due to a positive technical environment and slowly falling inflation. Furthermore,we tactically adjusted U.S. duration, utilizing both long- and short-duration positioning as interest rates shifted and we saw opportunities. Although the yield on the 10-year U.S. Treasury note increased to 3.01% at the end of the reporting period from 2.83% at the end of May, Treasury yields decreased late in the period. We had tactically added to U.S. duration before the market move, benefiting returns. Also, a position in Brazilian government bonds contributed as they rallied following the election of a market-friendly presidential candidate in October.

When determining portfolio allocation targets among the various fixed income sectors, we actively consider both current and potential future liquidity. U.S. Treasuries and the sovereign debt of other developed markets, such as Germany and the UK, are typically very liquid. However, liquidity tends to decrease in sectors withincreasing amounts of credit risk. Emerging market corporate bonds is an example of a sector that can be difficult to buy or sell efficiently in a “flight to quality” environment.

The fund maintains material holdings in various types of derivatives, primarily for hedging risk or gaining exposure to certain sectors or currencies. These derivatives had a marginally positive effect overall on absolute returns.

How is the fund positioned?

In general, the fund is conservatively positioned. The fund’s overall duration is shorter than the duration of the benchmark. Our interest rate exposure involves long relative duration positions in the U.S. as well as other high-quality sovereigns, including Germany and Australia. The portfolio has short relative duration positions in Japan, Italy, France, and the UK, where the turbulence surrounding the Brexit process could undermine investor confidence in government debt. The portfolio is overweight emerging market duration, although we have moderated this exposure. We favor emerging markets, including South Africa and Brazil, where idiosyncratic events have been driving the market, creating attractive valuations.

Our exposure to corporate bond markets remains modest relative to the portfolio’s history. Although credit spreads widened meaningfully near the end of the reporting period to reach their widest levels since 2016, we think that U.S. corporate spreads have the potential to increase further, particularly because we appear to be nearing the end of the U.S. credit cycle. (Credit spreads measure the additional yield that investors demand to hold a bond with credit risk relative to a comparable-maturity, high-quality government bond.) We use derivatives to hedge some of the portfolio’s broad exposure to credit risk. However, we rely on our credit analysts to find opportunities in specific corporate bonds, particularly those that our analysts identify as “all weather” issues that could better maintain their value late in the economic cycle. We are comfortable with this exposure to individual corporate bonds because we do not anticipate a recession or credit crisis in the short term.

In terms of currency positioning, the portfolio is underweight the U.S. dollar, primarily against the Japanese yen. We group our foreign exchange positions into three categories: hedges, income positions, and directional views. The yen position is a hedge, as it should benefit from the combination of lower oil prices (Japan is a major oil importer) and higher levels of global volatility (the yen tends to gain in times of global risk aversion). The portfolio also has positions in currencies that we believe will move up or down based on relative valuations or other factors. These directional positions include the euro, theIndonesian rupiah, and the South African rand against the U.S. dollar. Finally, we have positions in higher-yielding currencies, such as the Mexican peso, the Romanian leu, and the Malaysian ringgit, to enhance the portfolio’s income.

What is portfolio management’s outlook?

The European Central Bank plans to stop its asset purchases at the end of 2018, removing some support for the eurozone economy. The Japanese economic cycle continues to lag other developed markets, so we expect it will be some time before the Bank of Japan begins to taper its monetary easing measures. The Bank of England’s monetary policy trajectory is more ambiguous given the current uncertainty surrounding the Brexit process and its potential impact on the UK economy.

In the U.S., signs of softening growth have started to emerge. The Fed’s moves to normalize monetary policy, coupled with diminishing benefits from the Trump administration’s late-2017 tax cuts, are likely to further weigh on the U.S. economy. We anticipate that either the Chinese and European economies will gradually pick up, bringing a more balanced global expansion, or that a steep widening of credit spreads will force the Fed to pause—or end—its rate hikes. This environment of lower asset prices, a more dovish Fed, and a weaker U.S. dollar could set up a meaningful rally in riskier fixed income sectors.

However, while the Fed has taken small steps toward potentially slowing its rate increases by stressing the importance of data dependency, U.S. policymakers still seem to want to maintain their current pace of rate hikes. Although credit spreads have recently widened to some degree, causing financial conditions to tighten, conditions are still not particularly tight by historical standards, giving the U.S. central bank no reason to pause its rate increases. In this environment, the volatility that characterized much of 2018 would likely continue, benefiting high-quality global government bonds but leaving credit sectors at risk of a sell-off. We believe that we can position the portfolio for either market scenario by nimbly implementing tactical strategies based on evolving global economic data and financial conditions.

The views expressed reflect the opinions of T. Rowe Price as of the date of this report and are subject to change based on changes in market, economic, or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

RISKS OF BOND INVESTING

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 (fail 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.

Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. issuers. Foreign securities tend to be more volatile and less liquid than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, foreign investments are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. These risks are heightened for the fund’s investments in emerging markets, which are more susceptible to governmental interference, less efficient trading markets, and the imposition of local taxes or restrictions on gaining access to sales proceeds for foreign investors.

BENCHMARK INFORMATION

GROWTH OF $10,000

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 include a broad-based market index and may also include 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.

AVERAGE ANNUAL COMPOUND TOTAL RETURN

EXPENSE RATIO

FUND EXPENSE EXAMPLE

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.

Please note that the fund has three share classes: The original share class (Investor Class) charges no distribution and service (12b-1) fee, the Advisor Class shares are offered only through unaffiliated brokers and other financial intermediaries and charge a 0.25% 12b-1 fee, and I Class shares are available to institutionally oriented clients and impose no 12b-1 or administrative fee payment. Each share class is presented separately in the table.

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 Personal Services or Enhanced Personal Services client (enrollment in these programs generally requires T. Rowe Price assets of at least $250,000). 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.

NOTES TO FINANCIAL STATEMENTS

T. Rowe Price Global Multi-Sector Bond 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 to provide high income and some capital appreciation. The fund has three classes of shares: the Global Multi-Sector Bond Fund (Investor Class), the Global Multi-Sector Bond Fund–Advisor Class (Advisor Class), and the Global Multi-Sector Bond Fund–I Class (I Class). Advisor Class shares are sold only through unaffiliated brokers and other unaffiliated financial intermediaries.I Class shares generally are available only to investors meeting a $1,000,000 minimum investment, although the minimum is generally waived for certain client accounts. The Advisor Class operates under a Board-approved Rule 12b-1 plan pursuant to which the class compensates financial intermediaries for distribution, shareholder servicing, and/or certain administrative services; the Investor and I Classes do not pay Rule 12b-1 fees. Each class has exclusive voting rights on matters related solely to that class; separate voting rights on matters that relate to all classes; and, in all other respects, the same rights and obligations as the other classes.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Basis of PreparationThe fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB)Accounting Standards CodificationTopic 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. Certain ratios in the accompanying Financial Highlights have been included to conform to the current year presentation.

Investment Transactions, Investment Income, and Distributions Investment transactions are accounted for on the trade date basis. Income and expenses are recorded on the accrual basis. Realized gains and losses are reported on the identified cost 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. Inflation adjustments to the principal amount of inflation-indexed bonds are reflected as interest income. Income tax-related interest and penalties, if incurred, are recorded asincome tax expense. 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. Distributions to shareholders are recorded on the ex-dividend date. Income distributions are declared by each class daily and paid monthly. A capital gain distribution may also be declared and paid by the fund annually.

Currency TranslationAssets, 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 respective date of such transaction. The effect of changes in foreign currency exchange rates on realized and unrealized security gains and losses is not bifurcated from the portion attributable to changes in market prices.

Class Accounting Shareholder servicing, prospectus, and shareholder report expenses incurred by each class are charged directly to the class to which they relate. Expenses common to all 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. To the extent any expenses are waived or reimbursed in accordance with an expense limitation (see Note 6), the waiver or reimbursement is charged to the applicable class or allocated across the classes in the same manner as the related expense. The Advisor Class pays Rule 12b-1 fees, in an amount not exceeding 0.25% of the class’s average daily net assets.

New Accounting GuidanceIn March 2017, the FASB issued amended guidance to shorten the amortization period for certain callable debt securities held at a premium. The guidance is effective for fiscal years and interim periods beginning after December 15, 2018. Adoption will have no effect on the fund’s net assets or results of operations.

Indemnification In the normal course of business, the fund may provide indemnification in connection with its officers and directors, service providers, and/or private company investments. The fund’s maximum exposure under these arrangements is unknown; however, the risk of material loss is currently considered to be remote.

NOTE 2 - VALUATION

The fund’s financial instruments are valued and each class’s 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)

Level 3 – unobservable inputs

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 TechniquesDebt securities generally are traded in the over-the-counter (OTC) market and 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. 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.

Equity securities listed or regularly traded on a securities exchange or in the OTC market are valued at the last quoted sale price or, for certain markets, the official closing price at the time the valuations are made. OTC Bulletin Board securities are valued at the mean of the closing bid and asked prices. 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 closing bid and asked prices for domestic securities and the last quoted sale or closing price for international securities.

For valuation purposes, the last quoted prices of non-U.S. equity securities may be adjusted to reflect the fair value of such securities at the close of the NYSE. If the fund determines that developments between the close of a foreign market and the close of the NYSE will, affect the value of some or all of its portfolio securities, the fund will adjust the previous quoted prices to reflect what it believes to be the fair value of the securities as of the close of the NYSE. In deciding whether it is necessary to adjust quoted prices toreflect fair value, the fund reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U.S. markets that represent foreign securities and baskets of foreign securities. The fund may also fair value securities in other situations, such as when a particular foreign market is closed but the fund is open. The fund uses outside pricing services to provide it with quoted prices and information to evaluate or adjust those prices. The fund cannot predict how often it will use quoted prices and how often it will determine it necessary to adjust those prices to reflect fair value. As a means of evaluating its security valuation process, the fund routinely compares quoted prices, the next day’s opening prices in the same markets, and adjusted prices.

Actively traded equity securities listed on a domestic exchange generally are categorized in Level 1 of the fair value hierarchy. Non-U.S. equity securities generally are categorized in Level 2 of the fair value hierarchy despite the availability of quoted prices because, as described above, the fund evaluates and determines whether those quoted prices reflect fair value at the close of the NYSE or require adjustment. OTC Bulletin Board securities, certain preferred securities, and equity securities traded in inactive markets generally are categorized in Level 2 of the fair value hierarchy.

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. Listed options, and OTC options with a listed equivalent, are valued at the mean of the closing bid and asked prices and generally are categorized in Level 2 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. Forward currency exchange contracts are valued using the prevailing forward exchange rate and are categorized in Level 2 of the fair value hierarchy. Swaps are valued at prices furnished by an independent pricing service or independent swap dealers and generally are categorized in Level 2 of the fair value hierarchy; however, if unobservable inputs are significant to the valuation, the swap would be categorized in Level 3. 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 InputsThe following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on November 30, 2018 (for further detail by category, please refer to the accompanying Portfolio of Investments):

There were no material transfers between Levels 1 and 2 during the six months ended November 30, 2018.

Following is a reconciliation of the fund’s Level 3 holdings for the six months ended November 30, 2018. Gain (loss) reflects both realized and change in unrealized gain/loss on Level 3 holdings during the period, if any, and is included on the accompanying Statement of Operations. The change in unrealized gain/loss on Level 3 instruments held at November 30, 2018, totaled $(31,000) for the six months ended November 30, 2018. Transfers into and out of Level 3 are reflected at the value of the financial instrument at the beginning of the period. During the six months, transfers into Level 3 resulted from a lack of observable market data for the security and transfers out of Level 3 were because observable market data became available for the security.

NOTE 3 - DERIVATIVE INSTRUMENTS

During the six months ended November 30, 2018, 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, to enhance return, or to adjust portfolio duration and credit exposure. The risks associated with the use of derivatives are differentfrom, 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.

The following table summarizes the fair value of the fund’s derivative instruments held as of November 30, 2018, and the related location on the accompanying Statement of Assets and Liabilities, presented by primary underlying risk exposure:

Additionally, the amount of gains and losses on derivative instruments recognized in fund earnings during the six months ended November 30, 2018, and the related location on the accompanying Statement of Operations is summarized in the following table by primary underlying risk exposure:

Counterparty Risk and CollateralThe fund invests in derivatives in various markets, which expose it to differing levels of counterparty risk. Counterparty risk on exchange-traded and centrally cleared derivative contracts, such as futures, exchange-traded options, and centrally cleared swaps, 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.

Derivatives, such as bilateral swaps, forward currency exchange contracts, and OTC options, that are transacted and settle directly with a counterparty (bilateral derivatives) may expose the fund to greater counterparty risk. To mitigate this risk, the fund has entered into master netting arrangements (MNAs) with certain counterparties that permit net settlement under specified conditions and, for certain counterparties, also require the exchange of collateral to cover mark-to-market exposure. MNAs may be in the form of International Swaps and Derivatives Association master agreements (ISDAs) or foreign exchange letter agreements (FX letters).

MNAs provide the ability to offset amounts the fund owes a counterparty against amounts the counterparty owes the fund (net settlement). Both ISDAs and FX letters generally allow termination of transactions and net settlement upon the occurrence of contractually specified events, such as failure to pay or bankruptcy. In addition, ISDAs specify other events, the occurrence of which would allow one of the parties to terminate. For example, a downgrade in credit rating of a counterparty below a specified rating would allow the fund to terminate, while a decline in the fund’s net assets of more than a specified percentage would allow the counterparty to terminate. Upon termination, all transactions with that counterparty would be liquidated and a net termination amount settled. ISDAs include collateral agreements whereas FX letters do not. Collateral requirements are determined daily based on the net aggregate unrealized gain or loss on all bilateral derivatives with a counterparty, subject to minimum transfer amounts that typically range from $100,000 to $250,000. Any additional collateral required due to changes in security values is typically transferred the same business day.

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. Collateral pledged by counterparties is not included in the fund’s assets because the fund does not obtain effective control over those assets. For bilateral derivatives, collateral posted or received by the fund is held in asegregated account at the fund’s custodian. While typically not sold in the same manner as equity or fixed income securities, exchange-traded or centrally cleared derivatives may be closed out only on the exchange or clearinghouse where the contracts were traded, and OTC and bilateral derivatives may be unwound with counterparties or transactions assigned to other counterparties to allow the fund to exit the transaction. This ability is subject to the liquidity of underlying positions. As of November 30, 2018, securities valued at $1,800,000 had been posted by the fund to counterparties for bilateral derivatives. As of November 30, 2018, collateral pledged by counterparties to the fund for bilateral derivatives consisted of $260,000 cash and securities valued at $1,590,000. As of November 30, 2018, cash of $3,464,000 and securities valued at $1,968,000 had been posted by the fund for exchange-traded and/or centrally cleared derivatives.

Forward Currency Exchange ContractsThe fund is subject to foreign currency exchange rate risk in the normal course of pursuing its investment objectives. It uses forward currency exchange contracts (forwards) primarily to protect its non-U.S. dollar-denominated securities from adverse currency movements. A forward involves an obligation to purchase or sell a fixed amount of a specific currency on a future date at a price set at the time of the contract. Although certain forwards may be settled by exchanging only the net gain or loss on the contract, most forwards are settled with the exchange of the underlying currencies in accordance with the specified terms. Forwards are valued at the unrealized gain or loss on the contract, which reflects the net amount the fund either is entitled to receive or obligated to deliver, as measured by the difference between the forward exchange rates at the date of entry into the contract and the forward rates at the reporting date. Appreciated forwards are reflected as assets and depreciated forwards are reflected as liabilities on the accompanying Statement of Assets and Liabilities. Risks related to the use of forwards include the possible failure of counterparties to meet the terms of the agreements; that anticipated currency movements will not occur, thereby reducing the fund’s total return; and the potential for losses in excess of the fund’s initial investment. During the six months ended November 30, 2018, the volume of the fund’s activity in forwards, based on underlying notional amounts, was generally between 31% and 37% of net assets.

Futures ContractsThe 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 anagreed-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, 2018, the volume of the fund’s activity in futures, based on underlying notional amounts, was generally between 7% and 28% of net assets.

OptionsThe fund is subject to foreign currency exchange rate risk and credit risk in the normal course of pursuing its investment objectives and uses options to help manage such risks. The fund may use options to manage exposure to security prices, interest rates, foreign currencies, and credit quality; as an efficient means of adjusting exposure to all or a part of a target market; to enhance income; as a cash management tool; or to adjust credit exposure. Options are included in net assets at fair value, options purchased are included in Investments in Securities, and Options written are separately reflected as a liability on the accompanying Statement of Assets and Liabilities. Premiums on unexercised, expired options are recorded as realized gains or losses; premiums on exercised options are recorded as an adjustment to the proceeds from the sale or cost of the purchase. The difference between the premium and the amount received or paid in a closing transaction is also treated as realized gain or loss. In return for a premium paid, currency options give the holder the right, but not the obligation, to buy and sell currency at a specified exchange rate. In return for a premium paid, options on swaps give the holder the right, but not the obligation, to enter a specified swap contract on predefined terms. The exercise price of an option on a credit default swap is stated in terms of a specified spread that represents the cost of credit protection on the reference asset, including both the upfront premium to open the position and future periodic payments. The exercise price of an interest rate swap is stated in terms of a fixed interest rate; generally, there is no upfront payment to open the position. Risks related to the use of options include possible illiquidity of the options markets; trading restrictions imposed by an exchange or counterparty; movements in the underlying asset values and currency values and credit ratings; and, for Options written, potential losses in excess of the fund’s initial investment. During the six months ended November 30, 2018, the volume of the fund’s activity in options, based on underlying notional amounts, was generally between 0% and 13% of net assets.

SwapsThe fund is subject to interest rate risk and credit risk in the normal course of pursuing its investment objectives and uses swap contracts to help manage such risks. The fund may use swaps in an effort to manage both long and short exposure to changes in interest rates, inflation rates, and credit quality; to adjust overall exposure to certain markets; to enhance total return or protect the value of portfolio securities; to serve as a cash management tool; or to adjust portfolio duration and credit exposure. Swap agreements can be settled either directly with the counterparty (bilateral swap) or through a central clearinghouse (centrally cleared swap). Fluctuations in the fair value of a contract are reflected in unrealized gain or loss and are reclassified to realized gain or loss upon contract termination or cash settlement. Net periodic receipts or payments required by a contract increase or decrease, respectively, the value of the contract until the contractual payment date, at which time such amounts are reclassified from unrealized to realized gain or loss. For bilateral swaps, cash payments are made or received by the fund on a periodic basis in accordance with contract terms; unrealized gain on contracts and premiums paid are reflected as assets and unrealized loss on contracts and premiums received are reflected as liabilities on the accompanying Statement of Assets and Liabilities. For bilateral swaps, premiums paid or received are amortized over the life of the swap and are recognized as realized gain or loss in the Statement of Operations. For centrally cleared swaps, payments are made or received by the fund each day to settle the daily fluctuation in the value of the contract (variation margin). Accordingly, the value of a centrally cleared swap included in net assets is the 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.

Interest rate swaps are agreements to exchange cash flows based on the difference between specified interest rates applied to a notional principal amount for a specified period of time. Risks related to the use of interest rate swaps include the potential for unanticipated movements in interest or currency rates, the possible failure of a counterparty to perform in accordance with the terms of the swap agreements, potential government regulation that could adversely affect the fund’s swap investments, and potential losses in excess of the fund’s initial investment.

Credit default swaps are agreements where one party (the protection buyer) agrees to make periodic payments to another party (the protection seller) in exchange for protection against specified credit events, such as certain defaults and bankruptcies related to an underlying credit instrument, or issuer or index of such instruments. Upon occurrence of a specified credit event, the protection seller is required to pay the buyer the difference between the notional amount of the swap and the value of the underlying credit, either in the form of a net cash settlement or by paying the gross notional amountand accepting delivery of the relevant underlying credit. For credit default swaps where the underlying credit is an index, a specified credit event may affect all or individual underlying securities included in the index and will be settled based upon the relative weighting of the affected underlying security(ies) within the index. Generally, the payment risk for the seller of protection is inversely related to the current market price or credit rating of the underlying credit or the market value of the contract relative to the notional amount, which are indicators of the markets’ valuation of credit quality. As of November 30, 2018, the notional amount of protection sold by the fund totaled $310,000 (0.0% of net assets), which reflects the maximum potential amount the fund could be required to pay under such contracts. Risks related to the use of credit default swaps include the possible inability of the fund to accurately assess the current and future creditworthiness of underlying issuers, the possible failure of a counterparty to perform in accordance with the terms of the swap agreements, potential government regulation that could adversely affect the fund’s swap investments, and potential losses in excess of the fund’s initial investment.

During the six months ended November 30, 2018, the volume of the fund’s activity in swaps, based on underlying notional amounts, was generally between 4% and 16% of net assets.

NOTE 4 - OTHER INVESTMENT TRANSACTIONS

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.

Emerging and Frontier MarketsThe fund may invest, either directly or through investments in T. Rowe Price institutional funds, in securities of companies located in, issued by governments of, or denominated in or linked to the currencies of emerging and frontier market countries; at period-end, approximately 28% of the fund’s net assets were invested in emerging markets and 7% in frontier markets. Emerging markets, and to a greater extent frontier markets, generally have economic structures that are less diverse and mature, and political systems that are less stable, than developed countries. These markets may be subject to greater political, economic, and social uncertainty and differing regulatory environments that may potentially impact the fund’s ability to buy or sell certain securities or repatriate proceeds to U.S. dollars. Such securities are often subject to greater price volatility, less liquidity, and higher rates of inflation than U.S. securities. Investing in frontier markets is significantly riskier than investing in other countries, including emerging markets.

Noninvestment-Grade DebtAt November 30, 2018, approximately 30% of the fund’s net assets were invested, either directly or through its investment in T. Rowe Price institutional funds, in noninvestment-grade debt including “high yield” or “junk” bonds or leveraged loans. Noninvestment-grade debt issuers are more likely to suffer an adverse change in financial condition that would result in the inability to meet a financial obligation. The noninvestment-grade debt market may experience sudden and sharp price swings due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high-profile default, or a change in market sentiment. These events may decrease the ability of issuers to make principal and interest payments and adversely affect the liquidity or value, or both, of such securities. Accordingly, securities issued by such companies carry a higher risk of default and should be considered speculative.

Restricted SecuritiesThe 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.

Collateralized Loan Obligations The fund may invest in collateralized loan obligations (CLOs) which are entities backed by a diversified pool of syndicated bank loans. The cash flows of the CLO can be split into multiple segments, called “tranches” or “classes”, which will vary in risk profile and yield. The riskiest segments, which are the subordinate or “equity” tranches, bear the greatest risk of loss from defaults in the underlying assets of the CLO and serve to protect the other, more senior, tranches. Senior tranches will typically have higher credit ratings and lower yields than the securities underlying the CLO. Despite the protection from the more junior tranches, senior tranches can experience substantial losses.

TBA Purchase, Sale Commitments and Forward Settling Mortgage ObligationsThe fund may enter into to-be-announced (TBA) purchase or sale commitments (collectively, TBA transactions), pursuant to which it agrees to purchase or sell, respectively, mortgage-backed securities for a fixed unit price, with payment and delivery at a scheduled future date beyond the customary settlement period for such securities. With TBA transactions, the particular securities to be received or delivered by the fund are not identified at the trade date; however, the securities must meet specified terms, including issuer, rate, and mortgage term, and be within industry-accepted “good delivery” standards. The fund may enter into TBA transactions with the intention of taking possession of or relinquishing the underlying securities, may elect to extend the settlement by “rolling” the transaction, and/or may use TBA transactions to gain or reduce interim exposure to underlying securities. Until settlement, the fund maintains liquid assets sufficient to settle its commitment to purchase a TBA or, in the case of a sale commitment, the fund maintains an entitlement to the security to be sold.

To mitigate counterparty risk, the fund has entered into Master Securities Forward Transaction Agreements with counterparties that provide for collateral and the right to offset amounts due to or from those counterparties under specified conditions. Subject to minimum transfer amounts, collateral requirements are determined and transfers made based on the net aggregate unrealized gain or loss on all TBA commitments and other forward settling mortgage obligations with a particular counterparty (collectively, MSFTA Transactions). At any time, the fund’s risk of loss from a particular counterparty related to its MSFTA Transactions is the aggregate unrealized gain on appreciated MSFTA Transactions in excess of unrealized loss on depreciated MSFTA Transactions and collateral received, if any, from such counterparty. As of November 30, 2018, no collateral was pledged by the fund or counterparties for MSFTA Transactions.

Bank LoansThe fund may invest in bank loans, which represent an interest in amounts owed by a borrower to a syndicate of lenders. Bank loans are generally noninvestment grade and often involve borrowers whose financial condition is highly leveraged. Bank loans may be in the form of either assignments or participations. A loan assignment transfers all legal, beneficial, and economic rights to the buyer, and transfer typically requires consent of both the borrower and agent. In contrast, a loan participation generally entitles the buyer to receive the cash flows from principal, interest, and any fee payments on a portion of a loan; however, the seller continues to hold legal title to that portion of the loan. As a result, the buyer of a loan participation generally has no direct recourse against the borrower and is exposed to credit risk of both the borrower and seller of the participation. Bank loans often have extended settlement periods, generally may be repaid at any time at the option of the borrower, and may require additional principal to be funded at the borrowers’ discretion at a later date (e.g., unfunded commitments and revolving debt instruments). Until settlement, the fund maintains liquid assets sufficient to settle its unfunded loan commitments. The fund reflects both the funded portion of a bank loan as well as its unfunded commitment in the Portfolio of Investments. However, if a credit agreement provides no initial funding of a tranche, and funding of the full commitment at a future date(s) is at the borrower’s discretion and considered uncertain, a loan is reflected in the Portfolio of Investments only if, and only to the extent that, the fund has actually settled a funding commitment.

Securities LendingThe fund may lend its securities to approved borrowers to earn additional income. Its securities lending activities are administered by a lending agent in accordance with a securities lending agreement. Security loans generally do not have stated maturity dates, and the fund may recall a security at any time. The fund receives collateral in the form of cash or U.S. government securities, valued at 102% to 105% of the value of the securities on loan. Collateral is maintained over the life of the loan in an amount not less than the value of loaned securities; any additional collateral required dueto changes in security values is delivered to the fund the next business day. Cash collateral is invested in accordance with investment guidelines approved by fund management. Additionally, the lending agent indemnifies the fund against losses resulting from borrower default. Although risk is mitigated by the collateral and indemnification, the fund could experience a delay in recovering its securities and a possible loss of income or value if the borrower fails to return the securities, collateral investments decline in value, and the lending agent fails to perform. Securities lending revenue consists of earnings on invested collateral and borrowing fees, net of any rebates to the borrower, compensation to the lending agent, and other administrative costs. In accordance with GAAP, investments made with cash collateral are reflected in the accompanying financial statements, but collateral received in the form of securities is not. At November 30, 2018, the value of loaned securities was $8,806,000; the value of cash collateral and related investments was $9,481,000.

Mortgage-Backed SecuritiesThe 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. The fund also may invest in stripped MBS, created when a traditional MBS is split into an interest-only (IO) and a principal-only (PO) strip. MBS, including IOs and POs, 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. IOs also risk loss of invested principal from faster-than-anticipated prepayments.

OtherPurchases and sales of portfolio securities other than short-term and U.S. government securities aggregated $301,724,000 and $258,640,000, respectively, for the six months ended November 30, 2018. Purchases and sales of U.S. government securities aggregated $253,792,000 and $212,906,000, respectively, for the six months ended November 30, 2018.

NOTE 5 - 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. Distributions determined in accordance with federal income tax regulations may differ in amount or character from net investment income and realized gains for financial reportingpurposes. 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.

At November 30, 2018, the cost of investments for federal income tax purposes was $831,957,000. Net unrealized loss aggregated $22,986,000 at period-end, of which $10,125,000 related to appreciated investments and $33,111,000 related to depreciated investments.

NOTE 6 - RELATED PARTY TRANSACTIONS

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, equal to 0.20% of the fund’s average daily net assets, and a group fee. 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 0.265% for assets in excess of $650 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, 2018, the effective annual group fee rate was 0.29%.

The Advisor Class is subject to a contractual expense limitation through the limitation date indicated in the table below. During the limitation period, Price Associates is required to waive its management fee or pay any expenses (excluding interest, expenses related to borrowings, taxes, brokerage, and other non-recurring expenses permitted by the investment management agreement) that would otherwise cause the class’s ratio of annualized total expenses to average net assets (net expense ratio) to exceed its expense limitation. The class is required to repay Price Associates for expenses previously waived/paid to the extent the class’s net assets grow or expenses decline sufficiently to allow repayment without causing the class’s net expense ratio (after the repayment is taken into account) to exceed both: (1) the expense limitation in place at the time such amounts were waived; and (2) the class’s current expense limitation. However, no repayment will be made more than three years after the date of a payment or waiver.

The I Class is also subject to an operating expense limitation (I Class limit) pursuant to which Price Associates is contractually required to pay all operating expenses of the I Class, excluding management fees, interest, expenses related to borrowings, taxes, brokerage, and other non-recurring expenses permitted by the investment management agreement, to the extent such operating expenses, on an annualized basis, exceed the I Class limit. This agreement will continue through the limitation date indicated in the table below, and may be renewed, revised, or revoked only with approval of the fund’s Board. The I Class is required to repay Price Associates for expenses previously paid to the extent the class’s net assets grow or expenses decline sufficiently to allow repayment without causing the class’s operating expenses (after the repayment is taken into account) to exceed both: (1) the I Class limit in place at the time such amounts were paid; and (2) the current I Class limit. However, no repayment will be made more than three years after the date of a payment or waiver.

Pursuant to these agreements, expenses were waived/paid to Price Associates during the six months ended November 30, 2018 as indicated in the table below. Including these amount, expenses previously waived/paid by Price Associates in the amount of $725,000 remain subject to repayment by the fund at November 30, 2018. To the extent any expenses are waived or reimbursed in accordance with an expense limitation, the waiver or reimbursement is charged to the applicable class or allocated across the classes in the same manner as the related expense. Any repayment of expenses previously waived/paid by Price Associates during the period, if any, would be included in the net investment income and expense ratios presented on the accompanying Financial Highlights

In addition, the fund has entered into service agreements with Price Associates and two wholly owned subsidiaries of Price Associates, each an affiliate of the fund (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 Investor Class. For the six months ended November 30, 2018, expenses incurred pursuant to these service agreements were $34,000 for Price Associates; $152,000 for T. Rowe Price Services, Inc.; and $6,000 for T. Rowe Price Retirement Plan Services, Inc. All amounts due to and due from Price, exclusive of investment management fees payable, are presented net on the accompanying Statement of Assets and Liabilities.

The fund may invest its cash reserves in certain open-end management investment companies managed by Price Associates and considered affiliates of the fund: the T. Rowe Price Government Reserve Fund or the T. Rowe Price Treasury Reserve Fund, organized as money market funds, or the T. Rowe Price Short-Term Fund, a short-term bond fund (collectively, the Price Reserve Funds). 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. Cash collateral from securities lending is invested in the T. Rowe Price Short-Term Fund. The Price Reserve Funds pay no investment management fees.

The fund may also invest in certain other T. Rowe Price funds (Price Funds) as a means of gaining efficient and cost-effective exposure to certain markets. The fund does not invest for the purpose of exercising management or control; however, investments by the fund may represent a significant portion of an underlying Price Fund’s net assets. Each underlying Price Fund is an open-end management investment company managed by Price Associates and is considered an affiliate of the fund. To ensure that the fund does not incur duplicate management fees (paid by the underlying Price Fund(s) and the fund), Price Associates has agreed to permanently waive a portion of its management fee charged to the fund in an amount sufficient to fully offset that portion of management fees paid by each underlying Price Fund related to the fund’s investment therein. Annual management fee rates and amounts waived related to investments in the underlying Price Fund(s) for the six months ended November 30, 2018, are as follows:

Total management fee waived was $111,000, $5,000, and $18,000 for Investor Class, Advisor Class, and I Class, respectively, for the six months ended November 30, 2018.

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, 2018, the fund had no purchases or sales cross trades with other funds or accounts advised by Price Associates.
