Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated 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’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	1 year	3 years	5 years	10 years
Spectrum Income Fund | Spectrum Income Fund | USD ($)	64	202	351	786

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 24.1% of the average value of its portfolio.

Investments, Risks, and Performance Principal Investment Strategies

The fund broadly diversifies its assets among a set of T. Rowe Price mutual funds representing specific market segments. The fund, which normally invests in a variety of domestic and international bond funds, a money market fund, and an income-oriented stock fund, seeks to maintain broad exposure to several markets in an attempt to reduce the impact of markets that are declining and to benefit from good performance in particular market segments over time.

The fund can invest in funds holding high-quality domestic and foreign bonds, high-yield bonds (“junk” bonds), short- and long-term securities, dividend-paying stocks and other instruments (such as bank loans).

Within the ranges shown in the following table, the portfolio manager decides how much of the fund’s assets to allocate to underlying fund investments based on the outlook for, and on the relative valuations of, the underlying funds and the various markets in which they invest.

The fund may sell shares of the underlying funds for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.

Principal Risks

As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater during periods of market disruption or volatility, are summarized as follows:

Market conditions The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including political or regulatory developments, recessions, inflation, rapid interest rate changes, war or acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues. 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. 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.

Asset allocation The fund’s overall level of risk will directly correspond to the risks of the underlying funds in which it invests. By investing in many underlying funds, the fund has partial exposure to the risks of different areas of the market. However, the selection of the underlying funds and the allocation of the fund’s assets among the various asset classes, market sectors, and investment styles represented by those underlying funds could cause the fund to underperform other funds with a similar benchmark or investment objective.

Investments in other funds The fund bears the risk that its underlying funds will fail to successfully employ their investment strategies. One or more underlying fund’s underperformance or failure to meet its investment objectives as intended could cause the fund to underperform similarly managed funds.

Bond exposure An underlying bond fund’s share price can fall because of various factors affecting bonds or due to general weakness in the overall bond markets. The fund invests in underlying funds with varying levels of credit risk, interest rate risk, and liquidity risk. At times, participants in bond markets may develop concerns about the ability of certain issuers 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 bond markets and the related derivatives markets, which could hamper an underlying fund’s ability to sell the bonds in which it invests or to find and purchase suitable investments.

Interest rates The prices of, and the income generated by, bonds and other debt instruments held by an underlying fund may be affected by changes in interest rates. A rise in interest rates typically causes 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. Generally, underlying bond funds with longer weighted average maturities and durations carry greater interest rate risk.

Prepayments and extensions Underlying funds that invest in mortgage-backed securities, other asset-backed securities, or any debt instrument with an embedded call option are subject to prepayment risks because the principal on the security may be prepaid at any time, which could reduce the security’s yield and market value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the underlying fund’s 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.

Junk investing Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, and loans that are rated below investment grade, expose an underlying fund to greater volatility and credit risk than investments in securities that are rated investment-grade. Issuers of junk bonds and loans are usually not as strong financially and are more likely to suffer an adverse change in financial condition that would result in the inability to meet a financial obligation. As a result, bonds and loans rated below investment grade carry a higher risk of default and should be considered speculative.

Credit quality An issuer of a debt instrument held by an underlying fund could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. The fund’s exposure to credit risk is increased to the extent the fund invests in underlying funds that hold securities that are not considered investment-grade. Holdings that are rated below investment grade carry greater risk of default and erratic price swings due, in part, to potentially adverse changes in the credit quality of the issuer.

International investing Investing in funds that hold the securities of non-U.S. issuers involves special risks not typically associated with investing in funds that hold securities of U.S. issuers. Non-U.S. securities tend to be more volatile and have lower overall liquidity 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, investments outside the U.S. are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets.

Emerging markets Investing in funds that hold securities of issuers in emerging market countries involve greater risk and overall volatility than investing in funds that hold securities of issuers in the U.S. and developed markets. Emerging market countries tend to have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. In addition to the risks normally associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on an underlying fund’s investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates.

Bank loans Underlying funds that invest in bank loans expose the fund to additional risks beyond those normally associated with more traditional debt instruments. An underlying fund’s ability to receive payments in connection with a loan depends primarily on the financial condition of the borrower and whether or not a loan is secured by collateral, although there is no assurance that the collateral securing a loan will be sufficient to satisfy the loan obligation. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price and have significantly longer settlement periods than more traditional investments. Bank loans often involve borrowers whose financial condition is troubled or highly leveraged, which increases an underlying fund’s risk that the fund may not receive its proceeds in a timely manner or that the fund may incur losses in order to pay redemption proceeds to its shareholders.

Dividend-paying stocks To the extent the fund invests in an underlying fund that focuses on dividend-paying stocks, it is exposed to greater volatility and the risk of stock market declines that could cause the fund to underperform funds with similar objectives. Stocks of established companies paying high dividends may not participate in a broad market advance to the same degree as most other stocks, and a sharp rise in interest rates could cause a company to reduce or eliminate its dividend.

Liquidity An underlying fund may not be able to meet requests to redeem shares without significant dilution of the remaining shareholders’ interest in the fund. A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit a fund’s ability to purchase or sell holdings in a timely manner at a desired price. Reduced liquidity can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Large redemptions may also have a negative impact on an underlying fund’s overall liquidity.

Money market investments An underlying money market fund may not be able to maintain a stable $1.00 share price at all times. If a money market fund fails to maintain a stable net asset value, or if there is a perceived threat that a money market fund is likely to fail to maintain a stable net asset value, the underlying fund could experience significant redemption activity.

Performance

The following performance information provides some indication of the risks of investing in the fund. The fund’s performance information represents only past performance (before and after taxes) and is not necessarily an indication of future results.

The following bar chart illustrates how much returns can differ from year to year by showing calendar year returns and the best and worst calendar quarter returns during those years for the fund.
