and then redeem all of your shares at the end of those periods, that your investment has a 5% return
each year, and that the fund&#x2019;s operating expenses remain the same. The example also assumes that any
current expense limitation arrangement remains in place for the period noted in the previous table; therefore,
the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for
which the expense limitation arrangement is expected to continue. Although your actual costs may be higher

approximately 65% of its net assets in stocks and 35% of its net assets in fixed income securities, although
the amount may vary based on market conditions. The fund invests at least 25% of its net assets in fixed
income senior securities and may invest up to 35% of its net assets in foreign securities. &lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;When deciding upon overall
allocations between stocks and fixed income securities, the adviser may favor stocks when strong economic
growth is expected and may favor fixed income securities if the economy is expected to slow sufficiently
to hurt corporate profit growth. The fund also gains exposure to stocks and fixed income securities,
as well as specific asset classes, through investments in other T.&#160;Rowe Price mutual funds and/or exchange-traded
funds.&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The
fund invests in bonds, including foreign issues, which are primarily rated investment grade (i.e., assigned
one of the four highest credit ratings by credit rating agencies or by T.&#160;Rowe Price) and are chosen
from across the entire government, corporate, and mortgage- and asset-backed securities markets. Maturities
generally reflect the adviser&#x2019;s outlook for interest rates.&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;When selecting particular stocks, the adviser
examines relative values and prospects among growth- and value-oriented stocks, domestic and international
stocks, small- to large-cap stocks, and stocks of companies involved in activities related to commodities
and other real assets. Domestic stocks are drawn from the overall U.S. market and international stocks
are selected primarily from large companies in developed countries, although stocks in emerging markets
may also be purchased. This process draws heavily upon the adviser&#x2019;s proprietary stock research expertise.
While the fund maintains a well-diversified portfolio, its portfolio manager may at a particular time
shift stock selection toward markets or market sectors that appear to offer attractive value and appreciation
potential.&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;A
similar security selection process applies to bonds. When deciding whether to adjust duration, credit
risk exposure, or allocations among the various sectors (for example, high yield or &#x201c;junk&#x201d; bonds,
mortgage- and asset-backed securities, foreign bonds, and emerging markets bonds), the adviser weighs
such factors as the outlook for inflation and the economy, corporate earnings, &lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;expected
interest rate movements and currency valuations, and the yield advantage that lower-rated bonds may offer
over investment-grade bonds.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

in value more than bonds and may decline significantly over short time periods. There is a chance that
stock prices overall will decline because stock markets tend to move in cycles, with periods of rising
and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility
in the stock markets in which the fund invests or because of factors that affect a particular company
or industry.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

may develop concerns about the ability of certain issuers of debt instruments to make timely principal
and interest payments, or they may develop concerns about the ability of financial institutions that
make markets in certain debt instruments to facilitate an orderly market. Those concerns could cause
increased volatility and reduced liquidity in particular securities or in the overall fixed income markets
and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may
hamper the fund&#x2019;s ability to sell the debt instruments in which it invests or to find and purchase
suitable debt instruments.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest
rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices
and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes
in interest rates. Generally, funds with longer weighted average maturities and durations carry greater
interest rate risk. Changes in monetary policy made by central banks and/or governments are likely to
affect the interest rates or yields of the securities in which the fund invests.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

 &lt;/span&gt;&lt;span style="font-size:8.0pt; font-family:Arial; font-style:normal; font-weight:normal; text-decoration:none;"&gt;The
fund is subject to prepayment risks because the principal on mortgage-backed securities, asset-backed
securities, or any debt instrument with an embedded call option may be prepaid at any time, which could
reduce the security&#x2019;s yield and market value. The rate of prepayments tends to increase as interest
rates fall, which could cause the average maturity of the portfolio to shorten. Extension risk may result
from a rise in interest rates, which tends to make mortgage-backed securities, asset-backed securities,
and other callable debt instruments more volatile.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

markets. A variety of factors can increase the volatility of the fund&#x2019;s holdings and markets generally,
including economic, political, or regulatory developments, recessions, inflation, rapid interest rate
changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses
or other widespread public health issues (such as the coronavirus pandemic) and related governmental
and public responses (including sanctions). Certain events may cause instability across global markets,
including reduced liquidity and disruptions in trading markets, while some events may affect certain
geographic regions, countries, sectors, and industries more significantly than others. Government intervention
in markets may impact interest rates, market volatility, and security pricing. These adverse developments
may cause broad declines in market value due to short-term market movements or for significantly longer
periods during more prolonged market downturns.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

tend to be more volatile and have lower overall liquidity and trading volume than investments in U.S.
securities and may lose value because of adverse local, political, social, or economic developments overseas,

of non-U.S. issuers are subject to trading markets with potential governmental interference, varying
regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from
those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to
hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared
with U.S. markets. The fund&#x2019;s overall foreign investing risk is increased to the extent it has exposure

are subject to greater risk and overall volatility than investments in the U.S. and other developed markets.
Emerging market countries tend to have economic structures that are less diverse and mature, less developed
legal and regulatory regimes, and political systems that are less stable, than those of developed countries.
In addition to the risks associated with investing outside the U.S., emerging markets are more susceptible
to governmental interference, political and economic uncertainty, local taxes and restrictions on the
fund&#x2019;s investments, less efficient trading markets with lower overall liquidity, and more volatile
currency exchange rates.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions
in bond inventory, and rapid or unexpected changes in interest rates. Markets with lower overall liquidity
could lead to greater price volatility and limit the fund&#x2019;s ability to sell a holding at a suitable

table may also include one or more indexes that more closely aligns to the fund&#x2019;s investment strategy
(Strategy Benchmark(s)).&lt;/p&gt;
&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;In
addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder
may influence returns. After-tax returns are calculated using the historical highest individual federal
marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns
depend on an investor&#x2019;s tax situation and may differ from those shown. After-tax returns shown are
not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k)
account or an IRA. After-tax returns are shown only for the Investor Class and will differ for other
share classes.&lt;/p&gt;</rr:PerformanceTableNarrativeTextBlock>
