Transamerica Tactical Rotation

TRANSAMERICA TACTICAL ROTATION

Investment Objective:

Seeks capital appreciation.

Fees and Expenses:

This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Transamerica Funds. More information about these and other discounts is available from your financial professional and in the “Waivers and/or Reductions of Charges” section on page 26 of the fund’s prospectus and in the fund’s statement of additional information (SAI) under the heading “Purchase of Shares.”

Maximum deferred sales charge (load) (as a percentage of purchase price or redemption proceeds, whichever is lower)	none	1.00%	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses Transamerica Tactical Rotation		A	C	I
Management fees		0.55%	0.55%	0.55%
Distribution and service (12b-1) fees		0.30%	1.00%	none

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 shares at the end of those periods (unless otherwise indicated). 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:

If the shares are redeemed at the end of each period:

Expense Example Transamerica Tactical Rotation (USD $)	1 year	3 years
A	682	960
C	310	649
I	113	353

If the shares are not redeemed:

Expense Example, No Redemption Transamerica Tactical Rotation (USD $)	1 year	3 years
A	682	960
C	210	649
I	113	353

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.

Principal Investment Strategies:

The fund’s sub-adviser, AEGON USA Investment Management, LLC (the “sub-adviser”) seeks to achieve the fund’s objective by investing its assets primarily in a combination of underlying exchange traded funds (“ETFs”).

• Under normal circumstances, the sub-adviser expects to allocate substantially all of the fund’s assets among underlying index-based ETFs to achieve targeted exposure to global equities and short-term fixed income securities. The fund’s allocation of assets will generally vary as follows: 20% to 100% in global equities, including emerging and frontier markets; and 0% to 80% in short duration fixed income securities, inflation-protected securities and/or cash.

• The fund utilizes a tactical asset allocation strategy, which makes short-term adjustments to the fund’s asset mix utilizing the sub-adviser’s research on various risk and return factors, in an effort to better trade off risk and return as market and economic conditions change. The approach seeks to generate improved returns per unit of volatility, as compared to those from fixed weight or rules-based models. Further, the sub-adviser believes that a greater focus on short-term dynamics can improve the distribution of returns through lower volatility and reduction of “economic tail risk” (the risk posed by events that are relatively rare but can have a substantial impact on a fund).
  
  The sub-adviser actively and tactically rotates the fund’s assets among various asset classes in an effort to take advantage of changing economic conditions that the sub-adviser believes favor one asset class over another. Based on the analysis of various economic indicators, the sub-adviser will increase the allocation to the asset classes that the sub-adviser believes have a higher probability of contributing to the outperformance of the fund’s benchmark. Tactical strategies tend to have higher turnover than index funds or strategic funds that adhere to a long term allocation.

• The sub-adviser may periodically adjust the fund’s allocations to favor investments in those underlying ETFs that are expected to provide the most favorable outlook for achieving the fund’s investment objective.

Each underlying ETF has its own investment objective, principal investment strategies and investment risks.

The fund may be a significant shareholder in certain underlying ETFs. The sub-adviser may change the fund’s asset allocation and underlying ETFs at any time without shareholder approval and without notice to investors.

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions directly, or through ETFs, in cash and short-term debt securities without limit. During periods of defensive investing, it will be more difficult for the fund to achieve its objective.

Principal Risks:

Risk is inherent in all investing. Many factors affect the fund’s performance. There is no assurance the fund will meet its investment objective. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks (in alphabetical order) of investing in the fund. You may lose money if you invest in this fund.

• Active Trading – The fund is actively managed and may purchase and sell securities without regard to the length of time held. Active trading may have a negative impact on performance by increasing transaction costs and may generate greater amounts of net short-term capital gains, which, for shareholders holding shares in taxable accounts, would be subject to tax at ordinary income tax rates upon distribution.

• Asset Allocation – The sub-adviser allocates the fund’s assets among various underlying funds. These allocations may be unsuccessful in maximizing the fund’s return and/or avoiding investment losses, and may cause the fund to underperform other funds with a similar strategy.

• Cash Management and Defensive Investing – Money market instruments or short-term debt securities held by the fund for cash management or defensive investing purposes can fluctuate in value. Like other fixed income securities, they are subject to risk, including market, interest rate and credit risk. If the fund holds cash uninvested, the fund will be subject to the credit risk of the depository institution holding the cash, it will not earn income on the cash and the fund’s yield will go down. To the extent that the fund’s assets are used for cash management or defensive investing purposes, it will be more difficult for the fund to achieve its objective.

• Credit – If an issuer or guarantor of a security held by the fund or a counterparty to a financial contract with the fund defaults or is downgraded, or is perceived to be less creditworthy, or if the credit quality or value of any underlying assets declines, the value of your investment will decline. Junk bonds have a higher risk of default or are already in default and are considered speculative. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

• Currency – The value of the fund’s securities denominated in foreign currencies fluctuates as the rates of exchange between those currencies and the U.S. dollar change. Currency exchange rates can be volatile and are affected by, among other factors, the general economics of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation.

• Emerging Markets – Investments in the securities of issuers located in or principally doing business in emerging markets are subject to foreign securities risks. These risks are greater for investments in emerging markets. Emerging market countries tend to have economic, political and legal systems that are less fully developed and are less stable than those of more advanced countries. Low trading volumes may result in a lack of liquidity and in extreme price volatility.

• Equity Securities – Equity securities represent an ownership interest in an issuer, rank junior in a company’s capital structure and consequently may entail greater risk of loss than debt securities. Equity securities include common and preferred stocks. Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline.

• Expenses – Your actual costs of investing in the fund may be higher than the expenses shown in this prospectus for a variety of reasons. For example, expense ratios may be higher than those shown if overall net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile.

• Extension – If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.

• Foreign Securities – Investing in foreign securities is generally riskier than investing in U.S. securities. Foreign securities are subject to a number of additional risks, including nationalization or expropriation of assets, imposition of currency controls or restrictions, confiscatory taxation, political or financial instability and other adverse economic or political developments. Lack of information and less market regulation and accounting standards also may affect the value of these securities.

• Frontier Markets – Frontier market countries generally have smaller economies and even less developed capital markets than emerging markets countries, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries.

• Inflation-Protected Securities – Inflation-protected debt securities may react differently from other types of debt securities and tend to react to changes in “real” interest rates. Real interest rates represent nominal (stated) interest rates reduced by the expected impact of inflation. In general, the price of an inflation-protected debt security can fall when real interest rates rise, and can rise when real interest rates fall. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation. Also, the inflation index utilized by a particular inflation-protected security may not accurately reflect the true rate of inflation, in which case the market value of the security could be adversely affected.

• Interest Rate – Interest rates may go up, causing the value of the fund’s investments to decline. Debt securities have varying levels of sensitivity to changes in interest rates. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

• Manager – The sub-adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the sub-adviser in this process may not produce the desired results. This could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

• Market – The market prices of the fund’s securities may go down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates or currency rates, lack of liquidity in the markets or adverse investor sentiment. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. Market prices of securities also may go down due to events or conditions that affect particular sectors, industries or issuers. When market prices fall, the value of your investment will go down. The fund may experience a substantial or complete loss on any individual security. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities. In response to the financial crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the U.S. is changing many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.

• Portfolio Selection – The value of your investment may decrease if the sub-adviser’s judgment about the quality, relative yield, value or market trends affecting a particular security or issuer, industry, sector, region or market segment, or about the economy or interest rates is incorrect.

• Prepayment or Call – Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The fund also may lose any premium it paid on the security.

• Small and Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of small or medium capitalization companies. Small or medium capitalization companies may be more at risk than large capitalization companies because, among other things, they may have limited product lines, operating history, market or financial resources, or because they may depend on a limited management group. The prices of securities of small and medium capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions. Securities of small and medium capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

• Tactical Asset Allocation – Tactical asset allocation is an investment strategy that actively adjusts a fund’s asset allocation. The fund’s tactical asset management discipline may not work as intended. The fund may not achieve its objective and may not perform as well as other funds using other asset management styles, including those based on fundamental analysis (a method of evaluating a security that entails attempting to measure its intrinsic value by examining related economic, financial and other factors) or strategic asset allocation (a strategy that involves periodically rebalancing the portfolio in order to maintain a long-term goal for asset allocation). The sub-adviser’s evaluations and assumptions in selecting underlying funds or individual securities may be incorrect in view of actual market conditions, and may result in owning securities that underperform other securities.

• Underlying Exchange Traded Funds – Because the fund invests its assets in various underlying ETFs, its ability to achieve its investment objective depends largely on the performance of the underlying ETFs in which it invests. Each of the underlying ETFs in which the fund may invest has its own investment risks, and those risks can affect the value of the underlying ETFs’ shares and therefore the value of the fund’s investments. There can be no assurance that the investment objective of any underlying ETF will be achieved. To the extent that the fund invests more of its assets in one underlying ETF than in another, the fund will have greater exposure to the risks of that underlying ETF. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying ETFs in which it invests.
  
  Equity-based ETFs are subject to risks similar to those of stocks; fixed income-based ETFs are subject to risks similar to those of fixed-income securities. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up and down, and the fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs are subject to the following risks that do not apply to conventional funds: (i) the market price of an ETF’s shares may be above or below the shares’ net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are delisted from the exchange or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.

Performance:

No performance is shown for the fund. Performance information will appear in a future version of this prospectus once the fund has a full calendar year of performance information to report to investors.

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.

Principal Investment Strategies:

The fund’s sub-adviser, AEGON USA Investment Management, LLC (the “sub-adviser”) seeks to achieve the fund’s objective by investing its assets primarily in a combination of underlying exchange traded funds (“ETFs”).

• Under normal circumstances, the sub-adviser expects to allocate substantially all of the fund’s assets among underlying index-based ETFs to achieve targeted exposure to global equities, commodities and derivative securities, as well as U.S. and international fixed income securities. The fund’s allocation of its assets will generally vary as follows: 16% to 70% in global equities, including emerging markets; 0% to 8% in inflation-protected securities; 0% to 15% in commodities; 14% to 70% in fixed income securities; and 0% to 5% in derivative securities. The fixed income exposure may include U.S. and non-U.S. corporate bonds and U.S. Treasuries of any maturity, sovereign debt of developed and emerging market countries, and inflation-protected bonds.

• The fund utilizes a tactical asset allocation strategy, which makes short-term adjustments to the fund’s asset mix utilizing the sub-adviser’s research on various risk and return factors, in an effort to better trade off risk and return as market and economic conditions change. The approach seeks to generate improved returns per unit of volatility, as compared to those from fixed weight or rules-based models. Further, the sub-adviser believes that a greater focus on short-term dynamics can improve the distribution of returns through lower volatility and reduction of “economic tail risk” (the risk posed by events that are relatively rare but can have a substantial impact on a fund). The fund’s asset allocation exposures are expected to be implemented and adjusted through transactions in ETFs.

If the fund holds cash uninvested, the fund will be subject to the credit risk of the depository institution holding the cash, it will not earn income on the cash and the fund’s yield will go down. To the extent that the fund’s assets are used for cash management or defensive investing purposes, it will be more difficult for the fund to achieve its objective.

• Commodities – To the extent the fund invests in commodities or instruments whose performance is linked to the price of an underlying commodity or commodity index, the fund will be subject to the risks of investing in commodities, including regulatory, economic and political developments, weather events and natural disasters and market disruptions. The fund’s investment exposure to the commodities markets may subject the fund to greater volatility than investments in more traditional securities, such as stocks and bonds. Commodities and commodity-linked investments may be less liquid than other investments. Commodity-linked investments are subject to the credit risks associated with the issuer, and their values may decline substantially if the issuer’s creditworthiness deteriorates.

• Credit – If an issuer or guarantor of a security held by the fund or a counterparty to a financial contract with the fund defaults or is downgraded, or is perceived to be less creditworthy, or if the credit quality or value of any underlying assets declines, the value of your investment will decline. Junk bonds have a higher risk of default or are already in default and are considered speculative. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

Currency exchange rates can be volatile and are affected by, among other factors, the general economics of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation.

• Derivatives – Using derivatives exposes the fund to additional risks and can increase fund losses and reduce opportunities for gains when market prices, interest rates or the derivative instruments themselves behave in a way not anticipated by the fund. Using derivatives also can have a leveraging effect and increase fund volatility. The fund may also have to sell assets at inopportune times to satisfy its obligations. Derivatives may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the fund. The fund’s investments in derivative instruments may involve a small investment relative to the amount of investment exposure assumed and may result in losses exceeding the amounts invested in those instruments. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation are not yet fully known and may not be for some time. New regulation of derivatives may make them more costly, may limit their availability, or may otherwise adversely affect their value or performance.

• Emerging Markets – Investments in the securities of issuers located in or principally doing business in emerging markets are subject to foreign securities risks. These risks are greater for investments in emerging markets. Emerging market countries tend to have economic, political and legal systems that are less fully developed and are less stable than those of more advanced countries. Low trading volumes may result in a lack of liquidity and in extreme price volatility.

• Equity Securities – Equity securities represent an ownership interest in an issuer, rank junior in a company’s capital structure and consequently may entail greater risk of loss than debt securities. Equity securities include common and preferred stocks. Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline.

• Expenses – Your actual costs of investing in the fund may be higher than the expenses shown in this prospectus for a variety of reasons. For example, expense ratios may be higher than those shown if overall net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile.

• Extension – If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.

• Foreign Securities – Investing in foreign securities is generally riskier than investing in U.S. securities. Foreign securities are subject to a number of additional risks, including nationalization or expropriation of assets, imposition of currency controls or restrictions, confiscatory taxation, political or financial instability and other adverse economic or political developments. Lack of information and less market regulation and accounting standards also may affect the value of these securities.

• Inflation-Protected Securities – Inflation-protected debt securities may react differently from other types of debt securities and tend to react to changes in “real” interest rates. Real interest rates represent nominal (stated) interest rates reduced by the expected impact of inflation. In general, the price of an inflation-protected debt security can fall when real interest rates rise, and can rise when real interest rates fall.

Consequently, the fund is subject to the risk that the methods and analyses employed by the sub-adviser in this process may not produce the desired results. This could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

• Market – The market prices of the fund’s securities may go down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates or currency rates, lack of liquidity in the markets or adverse investor sentiment.

An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up and down, and the fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs are subject to the following risks that do not apply to conventional funds: (i) the market price of an ETF’s shares may be above or below the shares’ net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are delisted from the exchange or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.

Principal Investment Strategies:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund’s sub-adviser, AEGON USA Investment Management, LLC (the “sub-adviser”) seeks to achieve the fund’s objective by investing its assets primarily in a combination of underlying exchange traded funds (“ETFs”).

• Under normal circumstances, the sub-adviser expects to allocate substantially all of the fund’s assets among underlying index-based ETFs to achieve targeted exposure to global equities, commodities and derivative securities, as well as U.S. and international fixed income securities. The fund’s allocation of its assets will generally vary as follows: 16% to 70% in global equities, including emerging markets; 0% to 8% in inflation-protected securities; 0% to 15% in commodities; 14% to 70% in fixed income securities; and 0% to 5% in derivative securities. The fixed income exposure may include U.S. and non-U.S. corporate bonds and U.S. Treasuries of any maturity, sovereign debt of developed and emerging market countries, and inflation-protected bonds.

• The fund utilizes a tactical asset allocation strategy, which makes short-term adjustments to the fund’s asset mix utilizing the sub-adviser’s research on various risk and return factors, in an effort to better trade off risk and return as market and economic conditions change. The approach seeks to generate improved returns per unit of volatility, as compared to those from fixed weight or rules-based models. Further, the sub-adviser believes that a greater focus on short-term dynamics can improve the distribution of returns through lower volatility and reduction of “economic tail risk” (the risk posed by events that are relatively rare but can have a substantial impact on a fund). The fund’s asset allocation exposures are expected to be implemented and adjusted through transactions in ETFs.
  
  The sub-adviser actively and tactically allocates the fund’s assets among various asset classes in an effort to take advantage of changing economic conditions that the sub-adviser believes favor one asset class over another. Based on the analysis of various economic indicators, the sub-adviser will increase the allocation to the asset classes that the sub-adviser believes have a higher probability of contributing to the outperformance of the fund’s benchmark. Tactical strategies tend to have higher turnover than index funds or strategic funds that adhere to a long term allocation.

• The sub-adviser may periodically adjust the fund’s allocations to favor investments in those underlying ETFs that are expected to provide the most favorable outlook for achieving the fund’s investment objective.

Each underlying ETF has its own investment objective, principal investment strategies and investment risks.

The fund may be a significant shareholder in certain underlying ETFs. The sub-adviser may change the fund’s asset allocation and underlying ETFs at any time without shareholder approval and without notice to investors.

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions directly, or through ETFs, in cash and short-term debt securities without limit. During periods of defensive investing, it will be more difficult for the fund to achieve its objective.

Risk [Heading]

rr_RiskHeading

Principal Risks:

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing. Many factors affect the fund’s performance. There is no assurance the fund will meet its investment objective. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks (in alphabetical order) of investing in the fund. You may lose money if you invest in this fund.

• Active Trading – The fund is actively managed and may purchase and sell securities without regard to the length of time held. Active trading may have a negative impact on performance by increasing transaction costs and may generate greater amounts of net short-term capital gains, which, for shareholders holding shares in taxable accounts, would be subject to tax at ordinary income tax rates upon distribution.

• Asset Allocation – The sub-adviser allocates the fund’s assets among various underlying funds. These allocations may be unsuccessful in maximizing the fund’s return and/or avoiding investment losses, and may cause the fund to underperform other funds with a similar strategy.

• Cash Management and Defensive Investing – Money market instruments or short-term debt securities held by the fund for cash management or defensive investing purposes can fluctuate in value. Like other fixed income securities, they are subject to risk, including market, interest rate and credit risk. If the fund holds cash uninvested, the fund will be subject to the credit risk of the depository institution holding the cash, it will not earn income on the cash and the fund’s yield will go down. To the extent that the fund’s assets are used for cash management or defensive investing purposes, it will be more difficult for the fund to achieve its objective.

• Commodities – To the extent the fund invests in commodities or instruments whose performance is linked to the price of an underlying commodity or commodity index, the fund will be subject to the risks of investing in commodities, including regulatory, economic and political developments, weather events and natural disasters and market disruptions. The fund’s investment exposure to the commodities markets may subject the fund to greater volatility than investments in more traditional securities, such as stocks and bonds. Commodities and commodity-linked investments may be less liquid than other investments. Commodity-linked investments are subject to the credit risks associated with the issuer, and their values may decline substantially if the issuer’s creditworthiness deteriorates.

• Credit – If an issuer or guarantor of a security held by the fund or a counterparty to a financial contract with the fund defaults or is downgraded, or is perceived to be less creditworthy, or if the credit quality or value of any underlying assets declines, the value of your investment will decline. Junk bonds have a higher risk of default or are already in default and are considered speculative. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

• Currency – The value of the fund’s securities denominated in foreign currencies fluctuates as the rates of exchange between those currencies and the U.S. dollar change. Currency exchange rates can be volatile and are affected by, among other factors, the general economics of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation.

• Derivatives – Using derivatives exposes the fund to additional risks and can increase fund losses and reduce opportunities for gains when market prices, interest rates or the derivative instruments themselves behave in a way not anticipated by the fund. Using derivatives also can have a leveraging effect and increase fund volatility. The fund may also have to sell assets at inopportune times to satisfy its obligations. Derivatives may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the fund. The fund’s investments in derivative instruments may involve a small investment relative to the amount of investment exposure assumed and may result in losses exceeding the amounts invested in those instruments. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation are not yet fully known and may not be for some time. New regulation of derivatives may make them more costly, may limit their availability, or may otherwise adversely affect their value or performance.

• Emerging Markets – Investments in the securities of issuers located in or principally doing business in emerging markets are subject to foreign securities risks. These risks are greater for investments in emerging markets. Emerging market countries tend to have economic, political and legal systems that are less fully developed and are less stable than those of more advanced countries. Low trading volumes may result in a lack of liquidity and in extreme price volatility.

• Equity Securities – Equity securities represent an ownership interest in an issuer, rank junior in a company’s capital structure and consequently may entail greater risk of loss than debt securities. Equity securities include common and preferred stocks. Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline.

• Expenses – Your actual costs of investing in the fund may be higher than the expenses shown in this prospectus for a variety of reasons. For example, expense ratios may be higher than those shown if overall net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile.

• Extension – If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.

• Foreign Securities – Investing in foreign securities is generally riskier than investing in U.S. securities. Foreign securities are subject to a number of additional risks, including nationalization or expropriation of assets, imposition of currency controls or restrictions, confiscatory taxation, political or financial instability and other adverse economic or political developments. Lack of information and less market regulation and accounting standards also may affect the value of these securities.

• Inflation-Protected Securities – Inflation-protected debt securities may react differently from other types of debt securities and tend to react to changes in “real” interest rates. Real interest rates represent nominal (stated) interest rates reduced by the expected impact of inflation. In general, the price of an inflation-protected debt security can fall when real interest rates rise, and can rise when real interest rates fall. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation. Also, the inflation index utilized by a particular inflation-protected security may not accurately reflect the true rate of inflation, in which case the market value of the security could be adversely affected.

• Interest Rate – Interest rates may go up, causing the value of the fund’s investments to decline. Debt securities have varying levels of sensitivity to changes in interest rates. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

• Manager – The sub-adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the sub-adviser in this process may not produce the desired results. This could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

• Market – The market prices of the fund’s securities may go down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates or currency rates, lack of liquidity in the markets or adverse investor sentiment. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. Market prices of securities also may go down due to events or conditions that affect particular sectors, industries or issuers. When market prices fall, the value of your investment will go down. The fund may experience a substantial or complete loss on any individual security. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities. In response to the financial crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the U.S. is changing many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.

• Portfolio Selection – The value of your investment may decrease if the sub-adviser’s judgment about the quality, relative yield, value or market trends affecting a particular security or issuer, industry, sector, region or market segment, or about the economy or interest rates is incorrect.

• Prepayment or Call – Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The fund also may lose any premium it paid on the security.

• Tactical Asset Allocation – Tactical asset allocation is an investment strategy that actively adjusts a fund’s asset allocation. The fund’s tactical asset management discipline may not work as intended. The fund may not achieve its objective and may not perform as well as other funds using other asset management styles, including those based on fundamental analysis (a method of evaluating a security that entails attempting to measure its intrinsic value by examining related economic, financial and other factors) or strategic asset allocation (a strategy that involves periodically rebalancing the portfolio in order to maintain a long-term goal for asset allocation). The sub-adviser’s evaluations and assumptions in selecting underlying funds or individual securities may be incorrect in view of actual market conditions, and may result in owning securities that underperform other securities.

• Underlying Exchange Traded Funds – Because the fund invests its assets in various underlying ETFs, its ability to achieve its investment objective depends largely on the performance of the underlying ETFs in which it invests. Each of the underlying ETFs in which the fund may invest has its own investment risks, and those risks can affect the value of the underlying ETFs’ shares and therefore the value of the fund’s investments. There can be no assurance that the investment objective of any underlying ETF will be achieved. To the extent that the fund invests more of its assets in one underlying ETF than in another, the fund will have greater exposure to the risks of that underlying ETF. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying ETFs in which it invests.
  
  Equity-based ETFs are subject to risks similar to those of stocks; fixed income-based ETFs are subject to risks similar to those of fixed-income securities. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up and down, and the fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs are subject to the following risks that do not apply to conventional funds: (i) the market price of an ETF’s shares may be above or below the shares’ net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are delisted from the exchange or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.

Risk is inherent in all investing. Many factors affect the fund’s performance. There is no assurance the fund will meet its investment objective. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks (in alphabetical order) of investing in the fund. You may lose money if you invest in this fund.

• Active Trading – The fund is actively managed and may purchase and sell securities without regard to the length of time held. Active trading may have a negative impact on performance by increasing transaction costs and may generate greater amounts of net short-term capital gains, which, for shareholders holding shares in taxable accounts, would be subject to tax at ordinary income tax rates upon distribution.

• Asset Allocation – The sub-adviser allocates the fund’s assets among various underlying funds. These allocations may be unsuccessful in maximizing the fund’s return and/or avoiding investment losses, and may cause the fund to underperform other funds with a similar strategy.

• Cash Management and Defensive Investing – Money market instruments or short-term debt securities held by the fund for cash management or defensive investing purposes can fluctuate in value. Like other fixed income securities, they are subject to risk, including market, interest rate and credit risk. If the fund holds cash uninvested, the fund will be subject to the credit risk of the depository institution holding the cash, it will not earn income on the cash and the fund’s yield will go down.

• Currency – The value of the fund’s securities denominated in foreign currencies fluctuates as the rates of exchange between those currencies and the U.S. dollar change. Currency exchange rates can be volatile and are affected by, among other factors, the general economics of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation.

• Emerging Markets – Investments in the securities of issuers located in or principally doing business in emerging markets are subject to foreign securities risks. These risks are greater for investments in emerging markets. Emerging market countries tend to have economic, political and legal systems that are less fully developed and are less stable than those of more advanced countries. Low trading volumes may result in a lack of liquidity and in extreme price volatility.

• Equity Securities – Equity securities represent an ownership interest in an issuer, rank junior in a company’s capital structure and consequently may entail greater risk of loss than debt securities. Equity securities include common and preferred stocks. Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline.

• Expenses – Your actual costs of investing in the fund may be higher than the expenses shown in this prospectus for a variety of reasons. For example, expense ratios may be higher than those shown if overall net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile.

• Extension – If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.

• Foreign Securities – Investing in foreign securities is generally riskier than investing in U.S. securities. Foreign securities are subject to a number of additional risks, including nationalization or expropriation of assets, imposition of currency controls or restrictions, confiscatory taxation, political or financial instability and other adverse economic or political developments. Lack of information and less market regulation and accounting standards also may affect the value of these securities.

• Frontier Markets – Frontier market countries generally have smaller economies and even less developed capital markets than emerging markets countries, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries.

• Inflation-Protected Securities – Inflation-protected debt securities may react differently from other types of debt securities and tend to react to changes in “real” interest rates. Real interest rates represent nominal (stated) interest rates reduced by the expected impact of inflation. In general, the price of an inflation-protected debt security can fall when real interest rates rise, and can rise when real interest rates fall. Interest payments on inflation-protected debt securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation. Also, the inflation index utilized by a particular inflation-protected security may not accurately reflect the true rate of inflation, in which case the market value of the security could be adversely affected.

• Interest Rate – Interest rates may go up, causing the value of the fund’s investments to decline. Debt securities have varying levels of sensitivity to changes in interest rates. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

• Manager – The sub-adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses employed by the sub-adviser in this process may not produce the desired results. This could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

• Market – The market prices of the fund’s securities may go down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates or currency rates, lack of liquidity in the markets or adverse investor sentiment. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. Market prices of securities also may go down due to events or conditions that affect particular sectors, industries or issuers. When market prices fall, the value of your investment will go down. The fund may experience a substantial or complete loss on any individual security. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities. In response to the financial crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the U.S. is changing many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.

• Portfolio Selection – The value of your investment may decrease if the sub-adviser’s judgment about the quality, relative yield, value or market trends affecting a particular security or issuer, industry, sector, region or market segment, or about the economy or interest rates is incorrect.

• Prepayment or Call – Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The fund also may lose any premium it paid on the security.

• Small and Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of small or medium capitalization companies. Small or medium capitalization companies may be more at risk than large capitalization companies because, among other things, they may have limited product lines, operating history, market or financial resources, or because they may depend on a limited management group. The prices of securities of small and medium capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions. Securities of small and medium capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

• Tactical Asset Allocation – Tactical asset allocation is an investment strategy that actively adjusts a fund’s asset allocation. The fund’s tactical asset management discipline may not work as intended. The fund may not achieve its objective and may not perform as well as other funds using other asset management styles, including those based on fundamental analysis (a method of evaluating a security that entails attempting to measure its intrinsic value by examining related economic, financial and other factors) or strategic asset allocation (a strategy that involves periodically rebalancing the portfolio in order to maintain a long-term goal for asset allocation). The sub-adviser’s evaluations and assumptions in selecting underlying funds or individual securities may be incorrect in view of actual market conditions, and may result in owning securities that underperform other securities.

• Underlying Exchange Traded Funds – Because the fund invests its assets in various underlying ETFs, its ability to achieve its investment objective depends largely on the performance of the underlying ETFs in which it invests. Each of the underlying ETFs in which the fund may invest has its own investment risks, and those risks can affect the value of the underlying ETFs’ shares and therefore the value of the fund’s investments. There can be no assurance that the investment objective of any underlying ETF will be achieved. To the extent that the fund invests more of its assets in one underlying ETF than in another, the fund will have greater exposure to the risks of that underlying ETF. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying ETFs in which it invests.
  
  Equity-based ETFs are subject to risks similar to those of stocks; fixed income-based ETFs are subject to risks similar to those of fixed-income securities. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up and down, and the fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs are subject to the following risks that do not apply to conventional funds: (i) the market price of an ETF’s shares may be above or below the shares’ net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are delisted from the exchange or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.
