Spectrum Income Fund

SUMMARY

Spectrum Income Fund

Investment Objective

The fund seeks a high level of current income with moderate share price fluctuation.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

Fees and Expenses of the Fund

Shareholder fees (fees paid directly from your investment)

Shareholder Fees (USD $)		Spectrum Income Fund
Maximum sales charge (load) imposed on purchases	[1]	none
Maximum deferred sales charge (load)	[1]	none
Redemption fee	[1]	none
Maximum account fee	[1][2]	20

Annual fund operating expenses

(expenses that you pay each year as a

percentage of the value of your investment)

Annual Fund Operating Expenses		Spectrum Income Fund
Management fees	[1]	none
Distribution and service (12b-1) fees	[1]	none
Other expenses	[1]	none
Acquired fund fees and expenses	[1]	0.69%
Total annual fund operating expenses	[1]	0.69%

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. The example also assumes 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 (USD $)	1 year	3 years	5 years	10 years
Spectrum Income Fund	70	221	384	859

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 14.7% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund diversifies its assets widely among a set of T. Rowe Price mutual funds representing specific market segments. The fund, which normally invests in 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, and dividend-paying stocks.

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.

Asset Allocation Ranges for Underlying Funds
Income Fund	Investment Range
Corporate Income	0-10	%
Emerging Markets Bond	0-20
Equity Income	5-25
GNMA	5-20
High Yield	10-25
International Bond	0-20
New Income	10-30
Short-Term Bond	0-15
Summit Cash Reserves	0-25
U.S. Treasury Long-Term	0-15

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

Asset allocation risk The fund’s risks 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 many 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 and market sectors could cause the fund to underperform other funds with a similar investment objective.

Interest rate risk A rise in interest rates could cause the price of a bond fund in which the fund invests to fall. Generally, the longer the weighted average maturity of an underlying fund, the greater its interest rate risk.

Credit risk An issuer of a debt security or counterparty to an over-the-counter derivative held by an underlying bond fund could be downgraded or default, thereby negatively affecting the fund’s price or yield. The fund is exposed to greater credit risk to the extent it invests in underlying funds that hold high yield bonds. Issuers of high yield bonds are usually not as strong financially and the securities they issue carry a higher risk of default and should be considered speculative.

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

Foreign investing risk The fund’s investments in international funds may be adversely affected by economic conditions or developments overseas, or decreases in foreign currency values relative to the U.S. dollar. The risks are heightened for underlying funds that focus on emerging markets.

Dividend-paying stock risk To the extent the fund invests in an underlying fund that focuses on stocks, it is exposed to greater volatility and the risk of stock market declines that could cause the fund to underperform bond 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.

Performance

The bar chart showing calendar year returns and the average annual total returns table indicate risk by illustrating how much returns can differ from one year to the next and how fund performance compares with that of a comparable market index. The fund’s past performance (before and after taxes) is not necessarily an indication of future performance.

The fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted.

Spectrum Income Fund

Calendar Year Returns

	Quarter	Total
	Ended	Return
Best Quarter	6/30/09	9.91%
Worst Quarter	12/31/08	-5.40%

In addition, the average annual total returns table shows hypothetical after-tax returns to suggest 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’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 individual retirement account.

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 8.2% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund diversifies its assets widely among a set of T. Rowe Price mutual funds representing specific market segments. The fund, which normally invests in developed and emerging market equity funds, a money market fund, and, from time to time, international bond funds, 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 stock funds and, to a lesser degree, bond funds, which, in turn, have holdings in many different foreign countries, developed as well as emerging markets, and in both large and small companies.

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.

Asset Allocation Ranges for Underlying Funds
International Fund	Investment Range
Africa & Middle East	0-15	%
Emerging Europe	0-15
Emerging Markets Bond	0-15
Emerging Markets Stock	0-20
European Stock	0-30
International Bond	0-20

International Growth & Income	0-35
International Stock	0-55
Japan	0-30

Overseas Stock	0-35
Summit Cash Reserves	0-25

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

Asset allocation risk The fund’s risks 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 many 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 and market sectors could cause the fund to underperform other funds with a similar investment objective.

General equity risk Stocks generally fluctuate in value more than bonds and may decline significantly over short periods. As with any fund having equity exposure, the fund’s share price can fall because of overall weakness in the stock market. The value of a stock fund in which the fund invests may decline due to general market conditions or because of factors that affect a particular industry or market sector.

Foreign investing risk Investing in the securities of non-U.S. companies involves special risks not typically associated with investing in U.S. companies. Foreign securities tend to be more volatile and less liquid than investments in U.S. securities, and may lose value because of adverse 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.

Risks of bond and money market investing Bonds and money market securities have three main sources of risk. Interest rate risk is the risk that a rise in interest rates will cause the price of a debt security held by the fund to fall. Securities with longer maturities typically suffer greater declines than those with shorter maturities. Credit risk is the risk that an issuer of a debt security will default (fail to make scheduled interest or principal payments), potentially reducing the fund’s income level and share price. This risk is increased when a security is downgraded or the perceived creditworthiness of the issuer deteriorates. Liquidity risk is the risk that the fund may not be able to sell a holding in a timely manner at a desired price.

Performance

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. The example also assumes 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 (USD $)	1 year	3 years	5 years	10 years
Spectrum Growth Fund	82	255	444	990

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 13.0% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund diversifies its assets widely among a set of T. Rowe Price mutual funds representing specific market segments. The fund, which normally invests in domestic and international equity funds and a money market 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 domestic and foreign stocks, small-cap, mid-cap, and large-cap stocks, and growth and value stocks.

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.

Asset Allocation Ranges for Underlying Funds
Growth Fund	Investment Range
Blue Chip Growth	5-25	%
Emerging Markets Stock	0-10
Equity Income	5-25
Growth Stock	5-25
International Growth & Income	0-20
International Stock	0-20
Mid-Cap Growth	0-15
Mid-Cap Value	0-15
New Horizons	0-15
Real Assets	0-10
Small-Cap Value	0-15
Summit Cash Reserves	0-25
Value	5-25

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

Asset allocation risk The fund’s risks 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 many 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 and market sectors could cause the fund to underperform other funds with a similar investment objective.

General equity risk Stocks generally fluctuate in value more than bonds and may decline significantly over short periods. As with any fund having equity exposure, the fund’s share price can fall because of overall weakness in the stock market. The value of a stock fund in which the fund invests may decline due to general market conditions or because of factors that affect a particular industry or market sector.

Foreign investing risk The fund’s investments in international funds may be adversely affected by economic conditions or developments overseas, or decreases in foreign currency values relative to the U.S. dollar. The risks are heightened for underlying funds that focus on emerging markets.

Investment style risk Because the fund invests in stock funds with both growth and value characteristics, its share price may be negatively affected if either investing approach falls out of favor. Growth stocks tend to be more volatile than the overall stock market and are more sensitive to changes in current or expected earnings. Value stocks carry the risk that investors will not recognize their intrinsic value for a long time or that they are actually appropriately priced at a low level.

Small- and mid-cap stock risk Investing in small- and mid-cap funds entails greater risk than investing in funds that focus on larger companies. Stocks of smaller companies are usually more volatile than stocks of larger companies because smaller companies usually have more limited financial resources and less experienced management, and seldom pay significant dividends that could help to cushion returns in a falling market.

Risks of bond and money market investing Bonds and money market securities have three main sources of risk. Interest rate risk is the risk that a rise in interest rates will cause the price of a debt security held by the fund to fall. Securities with longer maturities typically suffer greater declines than those with shorter maturities. Credit risk is the risk that an issuer of a debt security will default (fail to make scheduled interest or principal payments), potentially reducing the fund’s income level and share price. This risk is increased when a security is downgraded or the perceived creditworthiness of the issuer deteriorates. Liquidity risk is the risk that the fund may not be able to sell a holding in a timely manner at a desired price.

Performance

The bar chart showing calendar year returns and the average annual total returns table indicate risk by illustrating how much returns can differ from one year to the next and how fund performance compares with that of a comparable market index. The fund’s past performance (before and after taxes) is not necessarily an indication of future performance.

The fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted.

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’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 individual retirement account.

rr_StrategyNarrativeTextBlock

The fund diversifies its assets widely among a set of T. Rowe Price mutual funds representing specific market segments. The fund, which normally invests in 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, and dividend-paying stocks.

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.

Asset Allocation Ranges for Underlying Funds
Income Fund	Investment Range
Corporate Income	0-10	%
Emerging Markets Bond	0-20
Equity Income	5-25
GNMA	5-20
High Yield	10-25
International Bond	0-20

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Asset allocation risk The fund’s risks 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 many 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 and market sectors could cause the fund to underperform other funds with a similar investment objective.

Interest rate risk A rise in interest rates could cause the price of a bond fund in which the fund invests to fall. Generally, the longer the weighted average maturity of an underlying fund, the greater its interest rate risk.

Credit risk An issuer of a debt security or counterparty to an over-the-counter derivative held by an underlying bond fund could be downgraded or default, thereby negatively affecting the fund’s price or yield. The fund is exposed to greater credit risk to the extent it invests in underlying funds that hold high yield bonds. Issuers of high yield bonds are usually not as strong financially and the securities they issue carry a higher risk of default and should be considered speculative.

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

Foreign investing risk The fund’s investments in international funds may be adversely affected by economic conditions or developments overseas, or decreases in foreign currency values relative to the U.S. dollar. The risks are heightened for underlying funds that focus on emerging markets.

Dividend-paying stock risk To the extent the fund invests in an underlying fund that focuses on stocks, it is exposed to greater volatility and the risk of stock market declines that could cause the fund to underperform bond 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.

Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 8.2% of the average value of its portfolio.

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. The example also assumes 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:

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund diversifies its assets widely among a set of T. Rowe Price mutual funds representing specific market segments. The fund, which normally invests in developed and emerging market equity funds, a money market fund, and, from time to time, international bond funds, 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 stock funds and, to a lesser degree, bond funds, which, in turn, have holdings in many different foreign countries, developed as well as emerging markets, and in both large and small companies.

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.

Asset Allocation Ranges for Underlying Funds
International Fund	Investment Range
Africa & Middle East	0-15	%
Emerging Europe	0-15
Emerging Markets Bond	0-15
Emerging Markets Stock	0-20
European Stock	0-30
International Bond	0-20
International Discovery	0-20
International Growth & Income	0-35
International Stock	0-55
Japan	0-30
Latin America	0-15
New Asia	0-20
Overseas Stock	0-35
Summit Cash Reserves	0-25

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.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Asset allocation risk The fund’s risks 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 many 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 and market sectors could cause the fund to underperform other funds with a similar investment objective.

General equity risk Stocks generally fluctuate in value more than bonds and may decline significantly over short periods. As with any fund having equity exposure, the fund’s share price can fall because of overall weakness in the stock market. The value of a stock fund in which the fund invests may decline due to general market conditions or because of factors that affect a particular industry or market sector.

Foreign investing risk Investing in the securities of non-U.S. companies involves special risks not typically associated with investing in U.S. companies. Foreign securities tend to be more volatile and less liquid than investments in U.S. securities, and may lose value because of adverse 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.

Risks of bond and money market investing Bonds and money market securities have three main sources of risk. Interest rate risk is the risk that a rise in interest rates will cause the price of a debt security held by the fund to fall. Securities with longer maturities typically suffer greater declines than those with shorter maturities. Credit risk is the risk that an issuer of a debt security will default (fail to make scheduled interest or principal payments), potentially reducing the fund’s income level and share price. This risk is increased when a security is downgraded or the perceived creditworthiness of the issuer deteriorates. Liquidity risk is the risk that the fund may not be able to sell a holding in a timely manner at a desired price.

[1] While the fund itself charges no management fee, it will indirectly bear its pro-rata share of the expenses of the underlying T. Rowe Price funds in which it invests (acquired funds). The acquired funds are expected to bear the operating expenses of the fund.

[2] Subject to certain exceptions, accounts with a balance of less than $10,000 are charged an annual $20 fee.

[3] Combined Index Portfolio is an unmanaged portfolio composed of S&P 500 Index (ranging from 80% - 87.5%) and MSCI EAFE Index (ranging from 12.5% - 20%) through 8/31/08. From 9/1/08 through 12/31/11 the portfolio was composed of Russell 3000 Index (ranging from 80% - 74%) and MSCI All Country World Index ex-USA (ranging from 20% - 26%). The indices and percentages may vary over time.
