Strategy [Heading]

Principal Investment Strategies:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund seeks to achieve its objective by investing globally in a range of securities, primarily equities with market capitalizations in excess of $750 million, which provide current income combined with the potential for capital appreciation. The fund normally invests primarily in securities intended to generate income, including (1) common stocks, (2) preferred stocks, including convertible securities, (3) master limited partnerships (“MLPs”) and (4) common shares of real estate investment trusts (“REITs”). The fund may also invest in fixed income securities of any maturity or credit quality, including high yield bonds rated below BBB by S&P or Fitch or Baa by Moody’s (commonly known as “junk bonds”). The fund invests without restriction as to issuer country, capitalization or currency.

Ranger International Management, LP (the “sub-adviser”) normally invests globally (including in emerging markets) in a variety of income-producing securities that the sub-adviser believes have attractive yields, and in the case of common stocks, the potential for dividend growth. The sub-adviser employs a bottom-up, fundamentals-based investment approach to security selection. The sub-adviser selects stock of issuers that it believes are stable and industry- or region-leading companies. The sub-adviser selects fixed income securities that it believes have the highest expected return among issuers of similar credit quality. The sub-adviser’s investment philosophy seeks domestic and international investment candidates characterized by (i) attractive yield, (ii) quality and (iii) financial strength.

The sub-adviser sells a security if the sub-adviser believes it is overvalued, more attractive candidates arise, or if there is a substantial, long term reduction in a company’s fundamental prospects that impair its value.

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions 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.

• Bank Obligations - To the extent the fund invests in U.S. bank obligations, the fund will be more susceptible to adverse events affecting the U.S. banking industry. Banks are sensitive to changes in money market and general economic conditions. Banks are highly regulated. Decisions by regulators may limit the loans banks make and the interest rates and fees they charge, and may reduce bank profitability.

• 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.

• Convertible Securities – Convertible securities share investment characteristics of both fixed income and equity securities. However, the value of these securities tends to vary more with fluctuations in the value of the underlying common stock than with fluctuations in interest rates. The value of convertible securities also tends to exhibit greater volatility than the underlying common stock. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The fund could lose money if the issuer of a convertible security is unable to meet its financial obligations or goes bankrupt.

• 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.

• Depositary Receipts – Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

• 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.

• Fixed-Income Securities – The market prices of fixed-income securities may fall due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In addition, the market value of a fixed income security may decline if the issuer or other obligor of the security fails to pay principal and/or interest, otherwise defaults or has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines. When market prices fall, the value of your investment will go down. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

• 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.

• Growth Stocks – Returns on growth stocks may not move in tandem with returns on other categories of stocks or the market as a whole. Growth stocks may be particularly susceptible to larger price swings or to adverse developments. Growth stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors “value” stocks.

• High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

• 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.

• Liquidity - Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

• 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.

• Master Limited Partnership –Investments in MLPs involve risks that differ from investments in corporate issuers, including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP’s general partner, cash flow risks, dilution risks and risks related to the general partner’s right to require unitholders to sell their common units at an undesirable time or price.

• 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.

• Preferred Stock –Preferred stock’s right to dividends and liquidation proceeds is junior to the rights of a company’s debt securities. The value of preferred stock may be subject to factors that affect fixed income and equity securities, including changes in interest rates and in a company’s creditworthiness. The value of preferred stock tends to vary more with fluctuations in the underlying common stock and less with fluctuations in interest rates and tends to exhibit greater volatility. Shareholders of preferred stock may suffer a loss of value if dividends are not paid and have limited voting rights.

• 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.

• REITs –Investing in real estate investment trusts (“REITs”) involves unique risks. When the fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. In addition to its own expenses, the fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. REITs are subject to a number of highly technical tax-related rules and requirements; and the failure to qualify as a REIT could result in corporate-level taxation, significantly reducing the return on an investment to the fund.

• 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.

• Valuation - The sales price the fund could receive for any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology.

• Warrants and Rights –Warrants and rights may be considered more speculative than certain other types of investments because they do not entitle a holder to the dividends or voting rights for the securities that may be purchased. They do not represent any rights in the assets of the issuing company, and cease to have value if not exercised prior to the expiration date.

• Yield –The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund’s expenses could absorb all or a significant portion of the fund’s income.

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions 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 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.

• Bank Obligations - To the extent the fund invests in U.S. bank obligations, the fund will be more susceptible to adverse events affecting the U.S. banking industry. Banks are sensitive to changes in money market and general economic conditions. Banks are highly regulated. Decisions by regulators may limit the loans banks make and the interest rates and fees they charge, and may reduce bank profitability.

• 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.

• Convertible Securities – Convertible securities share investment characteristics of both fixed income and equity securities. However, the value of these securities tends to vary more with fluctuations in the value of the underlying common stock than with fluctuations in interest rates. The value of convertible securities also tends to exhibit greater volatility than the underlying common stock. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The fund could lose money if the issuer of a convertible security is unable to meet its financial obligations or goes bankrupt.

• 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.

• Depositary Receipts – Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

• 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.

• Fixed-Income Securities – The market prices of fixed-income securities may fall due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In addition, the market value of a fixed income security may decline if the issuer or other obligor of the security fails to pay principal and/or interest, otherwise defaults or has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines. When market prices fall, the value of your investment will go down. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

• 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.

• Growth Stocks – Returns on growth stocks may not move in tandem with returns on other categories of stocks or the market as a whole. Growth stocks may be particularly susceptible to larger price swings or to adverse developments. Growth stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors “value” stocks.

• High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

• 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.

• Liquidity - Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

• 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.

• Master Limited Partnership – Investments in MLPs involve risks that differ from investments in corporate issuers, including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP’s general partner, cash flow risks, dilution risks and risks related to the general partner’s right to require unitholders to sell their common units at an undesirable time or price.

• 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.

• Preferred Stock – Preferred stock’s right to dividends and liquidation proceeds is junior to the rights of a company’s debt securities. The value of preferred stock may be subject to factors that affect fixed income and equity securities, including changes in interest rates and in a company’s creditworthiness. The value of preferred stock tends to vary more with fluctuations in the underlying common stock and less with fluctuations in interest rates and tends to exhibit greater volatility. Shareholders of preferred stock may suffer a loss of value if dividends are not paid and have limited voting rights.

• 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.

• REITs – Investing in real estate investment trusts (“REITs”) involves unique risks. When the fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. In addition to its own expenses, the fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. REITs are subject to a number of highly technical tax-related rules and requirements; and the failure to qualify as a REIT could result in corporate-level taxation, significantly reducing the return on an investment to the fund.

• 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.

• Valuation - The sales price the fund could receive for any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology.

• Warrants and Rights – Warrants and rights may be considered more speculative than certain other types of investments because they do not entitle a holder to the dividends or voting rights for the securities that may be purchased. They do not represent any rights in the assets of the issuing company, and cease to have value if not exercised prior to the expiration date.

• Yield – The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund’s expenses could absorb all or a significant portion of the fund’s income.

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 portfolio’s objective by investing its assets primarily in a combination of underlying exchange traded funds (“ETFs”), exchange traded notes (“ETNs”) and/or mutual funds.

• Under normal circumstances, the sub-adviser expects to allocate substantially all of the fund’s assets among underlying ETFs, ETNs and/or mutual funds to achieve targeted exposure to U.S. and international equities. The fund intends to achieve a mix over time of approximately 57% of fund assets in U.S. equities, 38% of fund assets in international equities, including emerging markets and frontier markets, and 5% of fund assets in 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 the reduction of “economic tail risk” (the risk posed by business cycle shifts that are relatively rare but can have a substantial impact on the returns of a fund). The fund’s asset allocation exposures are expected to be implemented and adjusted through transactions in ETFs, ETNs and/or mutual funds.
  
  The sub-adviser may periodically adjust the fund’s allocations to favor investments in those underlying ETFs, ETNs and/or mutual funds that are expected to provide the most favorable outlook for achieving the fund’s investment objective.

Each underlying ETF, ETN and/or mutual fund has its own investment objective, principal investment strategies and investment risks.

The fund may be a significant shareholder in certain underlying ETFs, ETNs and/or mutual funds. The sub-adviser may change the fund’s asset allocation and underlying ETFs, ETNs and/or mutual funds 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. 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.

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.

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.

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.

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”), exchange traded notes (“ETNs”) and/or mutual funds.

• Under normal circumstances, the sub-adviser expects to allocate substantially all of the fund’s assets among underlying ETFs, ETNs and/or mutual funds to achieve targeted exposure to global equities, commodities and derivative securities, as well as U.S. and international fixed income securities, including high-yield debt 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; and 0% to 5% in derivative securities. The derivatives allocation may include ETFs and/or ETNs (including leveraged, inverse and inverse leveraged ETFs and/or ETNs) that use derivatives to achieve or amplify the return (or the inverse of the return) of an underlying index or benchmark and futures.
  
  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 business cycle shifts that are relatively rare but can have a substantial impact on the returns of a fund). The fund’s asset allocation exposures are expected to be implemented and adjusted through transactions in ETFs, ETNs and/or mutual funds.
  
  The sub-adviser may periodically adjust the fund’s allocations to favor investments in those underlying ETFs, ETNs and/or mutual funds that are expected to provide the most favorable outlook for achieving the fund’s investment objective.

Each underlying ETF, ETN and/or mutual fund has its own investment objective, principal investment strategies and investment risks.

The fund may be a significant shareholder in certain underlying ETFs, ETNs and/or mutual funds. The sub-adviser may change the fund’s asset allocation and underlying ETFs, ETNs and/or mutual funds 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.

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.

High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

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.

Inverse Correlation – Shareholders should lose money when Variable Not Found rises, which is a result that is the opposite from traditional funds.

Leveraging – The value of your investment may be more volatile to the extent that the fund borrows or uses derivatives or other investments that have a leveraging effect on the fund. Other risks also will be compounded. This is because leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the fund would otherwise have had. The fund also may have to sell assets at inopportune times to satisfy its obligations.

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.

Tax – In order to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code, the fund must meet certain requirements regarding, among other things, the composition of its income. Any income the fund derives from investments in certain hard asset ETFs, such as certain commodity ETFs, and from other non-qualifying sources must generally be limited to a maximum of 10% of the fund’s gross income. If the fund fails to meet the 10% requirement, the fund may be disqualified as a RIC, in which case it would be subject to federal income tax on its net income at regular corporate rates (without reduction for distributions to shareholders). When distributed, that income might also be taxable to shareholders as an ordinary dividend to the extent attributable to the fund’s earnings and profits. If the fund were to fail to qualify as a RIC, shareholders of the fund could realize significantly diminished returns from their investment in the fund. In the alternative, the fund may be able to preserve its RIC qualification under those circumstances by meeting certain conditions, in which case it would be subject to a tax equal to the amount by which the income from non-qualifying sources exceeds the 10% limit.

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.

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”), exchange traded notes (“ETNs”) and/or mutual funds.

• Under normal circumstances, the sub-adviser expects to allocate substantially all of the fund’s assets among underlying ETFs, ETNs and/or mutual funds to achieve targeted exposure to global equities, commodities and derivative securities, as well as U.S. and international fixed income securities, including high-yield debt 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; and 0% to 5% in derivative securities. The derivatives allocation may include ETFs and/or ETNs (including leveraged, inverse and inverse leveraged ETFs and/or ETNs) that use derivatives to achieve or amplify the return (or the inverse of the return) of an underlying index or benchmark and futures.
  
  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 business cycle shifts that are relatively rare but can have a substantial impact on the returns of a fund). The fund’s asset allocation exposures are expected to be implemented and adjusted through transactions in ETFs, ETNs and/or mutual funds.
  
  The sub-adviser may periodically adjust the fund’s allocations to favor investments in those underlying ETFs, ETNs and/or mutual funds that are expected to provide the most favorable outlook for achieving the fund’s investment objective.

Each underlying ETF, ETN and/or mutual fund has its own investment objective, principal investment strategies and investment risks.

The fund may be a significant shareholder in certain underlying ETFs, ETNs and/or mutual funds. The sub-adviser may change the fund’s asset allocation and underlying ETFs, ETNs and/or mutual funds 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 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.

High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

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.

Inverse Correlation – Shareholders should lose money when Variable Not Found rises, which is a result that is the opposite from traditional funds.

Leveraging – The value of your investment may be more volatile to the extent that the fund borrows or uses derivatives or other investments that have a leveraging effect on the fund. Other risks also will be compounded. This is because leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the fund would otherwise have had. The fund also may have to sell assets at inopportune times to satisfy its obligations.

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.

Tax – In order to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code, the fund must meet certain requirements regarding, among other things, the composition of its income. Any income the fund derives from investments in certain hard asset ETFs, such as certain commodity ETFs, and from other non-qualifying sources must generally be limited to a maximum of 10% of the fund’s gross income. If the fund fails to meet the 10% requirement, the fund may be disqualified as a RIC, in which case it would be subject to federal income tax on its net income at regular corporate rates (without reduction for distributions to shareholders). When distributed, that income might also be taxable to shareholders as an ordinary dividend to the extent attributable to the fund’s earnings and profits. If the fund were to fail to qualify as a RIC, shareholders of the fund could realize significantly diminished returns from their investment in the fund. In the alternative, the fund may be able to preserve its RIC qualification under those circumstances by meeting certain conditions, in which case it would be subject to a tax equal to the amount by which the income from non-qualifying sources exceeds the 10% limit.

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.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the fund’s sub-adviser, Belle Haven Investments, L.P. (the “sub-adviser”), invests at least 80% of the fund’s net assets (plus the amount of borrowings, if any, for investment purposes) in municipal fixed-income securities the interest from which is exempt from federal income tax and the federal alternative minimum tax (AMT) applicable to individuals. The fund invests primarily in general obligation and revenue bonds issued by U.S. municipal issuers, as well as issuers in U.S. territories and possessions.

The fund is an actively managed, total return strategy that seeks to identify inefficiencies in the municipal bond market. The fund will invest utilizing a process that seeks to maximize total return, while adhering to longer term strategic risk management through a disciplined commitment to the diversification benefits of investment in a number of security types within the municipal bond market. The fund does this by taking a flexible approach to where it identifies value opportunities regardless of the par value. The sub-adviser also has the flexibility to invest in a broad array of credit issues, although the fund is expected to have an investment grade bias.

Under normal conditions, the duration of the fund will generally vary between 3 and 10 years. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security to changes in interest rates. The fund’s holdings may range in maturity from overnight to approximately 20 years. A fixed income security’s maturity is the date at which the security’s issuer legally agrees to repay the principal.

The fund may invest no more than 25% of its assets in securities of issuers in the same state, political subdivision or U.S. territory. The fund may invest up to 20% of its net assets in taxable investments, including U.S. high yield fixed income securities (commonly known as “junk bonds”) rated B or lower, which are those securities rated below investment grade by at least one nationally recognized statistical rating organization, or, if unrated, determined by the sub-adviser to be of comparable quality.

The fund may invest in derivative instruments such as options and futures contracts on U.S. Treasury securities for hedging purposes. The fund may also invest in exchange traded funds (“ETFs”).

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions 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.

• 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.

• 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.

• Exchange Traded Funds – 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. ETF shares may trade at a premium or discount to net asset value. ETFs are subject to secondary market trading risks. In addition, a fund will bear a pro rata portion of the operating expenses of an ETF in which it invests.

• 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.

• High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

• 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.

• Liquidity - Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

• 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.

• Municipal Securities - Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. To the extent the fund invests significantly in a single state or in securities the payments on which are dependent upon a single project or source of revenues, or that relate to a sector or industry, the fund will be more susceptible to associated risks and developments.

• 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.

• Taxable Investments. Although distributions of interest income from the fund’s tax-exempt securities are generally exempt from regular federal income tax, distributions from other sources, including capital gain distributions, and any gains on the sale of your shares are not. In addition, the interest on the fund’s municipal securities could become subject to regular federal income tax due to noncompliant conduct by issuers, unfavorable legislation or litigation, or adverse interpretations by regulatory authorities. You should consult a tax adviser about whether an alternative minimum tax applies to you and about state and local taxes on your fund distributions.

• Valuation - The sales price the fund could receive for any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology.

Strategy [Heading]

rr_StrategyHeading

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 portfolio’s objective by investing its assets primarily in a combination of underlying exchange traded funds (“ETFs”), exchange traded notes (“ETNs”) and/or mutual funds.

• Under normal circumstances, the sub-adviser expects to allocate substantially all of the fund’s assets among underlying ETFs, ETNs and/or mutual funds to achieve targeted exposure to U.S. and international equities. The fund intends to achieve a mix over time of approximately 57% of fund assets in U.S. equities, 38% of fund assets in international equities, including emerging markets and frontier markets, and 5% of fund assets in 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 the reduction of “economic tail risk” (the risk posed by business cycle shifts that are relatively rare but can have a substantial impact on the returns of a fund). The fund’s asset allocation exposures are expected to be implemented and adjusted through transactions in ETFs, ETNs and/or mutual funds.
  
  The sub-adviser may periodically adjust the fund’s allocations to favor investments in those underlying ETFs, ETNs and/or mutual funds that are expected to provide the most favorable outlook for achieving the fund’s investment objective.

Each underlying ETF, ETN and/or mutual fund has its own investment objective, principal investment strategies and investment risks.

The fund may be a significant shareholder in certain underlying ETFs, ETNs and/or mutual funds. The sub-adviser may change the fund’s asset allocation and underlying ETFs, ETNs and/or mutual funds 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. 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.

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.

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.

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.

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.

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 Enhanced Muni (USD $)	1 year	3 years
A	408	616
C	246	505
I	73	227

If the shares are not redeemed:

Expense Example, No Redemption Transamerica Enhanced Muni (USD $)	1 year	3 years
A	408	616
C	146	505
I	73	227

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:

Under normal circumstances, the fund’s sub-adviser, Belle Haven Investments, L.P. (the “sub-adviser”), invests at least 80% of the fund’s net assets (plus the amount of borrowings, if any, for investment purposes) in municipal fixed-income securities the interest from which is exempt from federal income tax and the federal alternative minimum tax (AMT) applicable to individuals. The fund invests primarily in general obligation and revenue bonds issued by U.S. municipal issuers, as well as issuers in U.S. territories and possessions.

The fund is an actively managed, total return strategy that seeks to identify inefficiencies in the municipal bond market. The fund will invest utilizing a process that seeks to maximize total return, while adhering to longer term strategic risk management through a disciplined commitment to the diversification benefits of investment in a number of security types within the municipal bond market. The fund does this by taking a flexible approach to where it identifies value opportunities regardless of the par value. The sub-adviser also has the flexibility to invest in a broad array of credit issues, although the fund is expected to have an investment grade bias.

Under normal conditions, the duration of the fund will generally vary between 3 and 10 years. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security to changes in interest rates. The fund’s holdings may range in maturity from overnight to approximately 20 years. A fixed income security’s maturity is the date at which the security’s issuer legally agrees to repay the principal.

The fund may invest no more than 25% of its assets in securities of issuers in the same state, political subdivision or U.S. territory. The fund may invest up to 20% of its net assets in taxable investments, including U.S. high yield fixed income securities (commonly known as “junk bonds”) rated B or lower, which are those securities rated below investment grade by at least one nationally recognized statistical rating organization, or, if unrated, determined by the sub-adviser to be of comparable quality.

The fund may invest in derivative instruments such as options and futures contracts on U.S. Treasury securities for hedging purposes. The fund may also invest in exchange traded funds (“ETFs”).

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions 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.

• 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.

• 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.

• Exchange Traded Funds – 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. ETF shares may trade at a premium or discount to net asset value. ETFs are subject to secondary market trading risks. In addition, a fund will bear a pro rata portion of the operating expenses of an ETF in which it invests.

• 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.

• High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

• 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.

• Liquidity - Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

• 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.

• Municipal Securities - Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. To the extent the fund invests significantly in a single state or in securities the payments on which are dependent upon a single project or source of revenues, or that relate to a sector or industry, the fund will be more susceptible to associated risks and developments.

• 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.

• Taxable Investments. Although distributions of interest income from the fund’s tax-exempt securities are generally exempt from regular federal income tax, distributions from other sources, including capital gain distributions, and any gains on the sale of your shares are not. In addition, the interest on the fund’s municipal securities could become subject to regular federal income tax due to noncompliant conduct by issuers, unfavorable legislation or litigation, or adverse interpretations by regulatory authorities. You should consult a tax adviser about whether an alternative minimum tax applies to you and about state and local taxes on your fund distributions.

• Valuation - The sales price the fund could receive for any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology.

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.

[1] Other expenses are based on estimates for the current fiscal year.

[2] Contractual arrangements have been made with the fund's investment adviser, Transamerica Asset Management, Inc. ("TAM"), through October 31, 2013, to waive fees and/or reimburse fund expenses to the extent that the fund's total operating expenses exceed 0.71%, excluding, as applicable, 12b-1 fees, acquired fund fees and expenses, interest, taxes, brokerage commissions, dividend and interest expenses on securities sold short, extraordinary expenses and other expenses not incurred in the ordinary course of the fund's business. TAM is entitled to reimbursement by the fund of fees waived or expenses reduced during any of the previous 36 months if on any day or month the estimated annualized fund operating expenses are less than the cap. In addition, 0.15% of the 0.30% 12b-1 fee for Class A shares and 0.25% of the 1.00% 12b-1 fee for Class C shares will be contractually waived through October 31, 2013.

Expense Example (USD $)	1 year	3 years
Class I2 TRANSAMERICA INCOME & GROWTH I2	84	262

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 seeks to achieve its objective by investing globally in a range of securities, primarily equities with market capitalizations in excess of $750 million, which provide current income combined with the potential for capital appreciation. The fund normally invests primarily in securities intended to generate income, including (1) common stocks, (2) preferred stocks, including convertible securities, (3) master limited partnerships (“MLPs”) and (4) common shares of real estate investment trusts (“REITs”). The fund may also invest in fixed income securities of any maturity or credit quality, including high yield bonds rated below BBB by S&P or Fitch or Baa by Moody’s (commonly known as “junk bonds”). The fund invests without restriction as to issuer country, capitalization or currency.

Ranger International Management, LP (the “sub-adviser”) normally invests globally (including in emerging markets) in a variety of income-producing securities that the sub-adviser believes have attractive yields, and in the case of common stocks, the potential for dividend growth. The sub-adviser employs a bottom-up, fundamentals-based investment approach to security selection. The sub-adviser selects stock of issuers that it believes are stable and industry- or region-leading companies. The sub-adviser selects fixed income securities that it believes have the highest expected return among issuers of similar credit quality. The sub-adviser’s investment philosophy seeks domestic and international investment candidates characterized by (i) attractive yield, (ii) quality and (iii) financial strength.

The sub-adviser sells a security if the sub-adviser believes it is overvalued, more attractive candidates arise, or if there is a substantial, long term reduction in a company’s fundamental prospects that impair its value.

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions 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.

• Bank Obligations - To the extent the fund invests in U.S. bank obligations, the fund will be more susceptible to adverse events affecting the U.S. banking industry. Banks are sensitive to changes in money market and general economic conditions. Banks are highly regulated. Decisions by regulators may limit the loans banks make and the interest rates and fees they charge, and may reduce bank profitability.

• 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.

• Convertible Securities – Convertible securities share investment characteristics of both fixed income and equity securities. However, the value of these securities tends to vary more with fluctuations in the value of the underlying common stock than with fluctuations in interest rates. The value of convertible securities also tends to exhibit greater volatility than the underlying common stock. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The fund could lose money if the issuer of a convertible security is unable to meet its financial obligations or goes bankrupt.

• 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.

• Depositary Receipts – Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

• 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.

• Fixed-Income Securities – The market prices of fixed-income securities may fall due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In addition, the market value of a fixed income security may decline if the issuer or other obligor of the security fails to pay principal and/or interest, otherwise defaults or has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines. When market prices fall, the value of your investment will go down. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

• 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.

• Growth Stocks – Returns on growth stocks may not move in tandem with returns on other categories of stocks or the market as a whole. Growth stocks may be particularly susceptible to larger price swings or to adverse developments. Growth stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors “value” stocks.

• High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

• 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.

• Liquidity - Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

• 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.

• Master Limited Partnership – Investments in MLPs involve risks that differ from investments in corporate issuers, including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP’s general partner, cash flow risks, dilution risks and risks related to the general partner’s right to require unitholders to sell their common units at an undesirable time or price.

• 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.

• Preferred Stock – Preferred stock’s right to dividends and liquidation proceeds is junior to the rights of a company’s debt securities. The value of preferred stock may be subject to factors that affect fixed income and equity securities, including changes in interest rates and in a company’s creditworthiness. The value of preferred stock tends to vary more with fluctuations in the underlying common stock and less with fluctuations in interest rates and tends to exhibit greater volatility. Shareholders of preferred stock may suffer a loss of value if dividends are not paid and have limited voting rights.

• 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.

• REITs – Investing in real estate investment trusts (“REITs”) involves unique risks. When the fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. In addition to its own expenses, the fund will indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests. REITs are subject to a number of highly technical tax-related rules and requirements; and the failure to qualify as a REIT could result in corporate-level taxation, significantly reducing the return on an investment to the fund.

• 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.

• Valuation - The sales price the fund could receive for any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology.

• Warrants and Rights – Warrants and rights may be considered more speculative than certain other types of investments because they do not entitle a holder to the dividends or voting rights for the securities that may be purchased. They do not represent any rights in the assets of the issuing company, and cease to have value if not exercised prior to the expiration date.

• Yield – The amount of income received by the fund will go up or down depending on day-to-day variations in short-term interest rates, and when interest rates are very low the fund’s expenses could absorb all or a significant portion of the fund’s income.

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 seeks to achieve its objective by investing globally in a range of securities, primarily equities with market capitalizations in excess of $750 million, which provide current income combined with the potential for capital appreciation. The fund normally invests primarily in securities intended to generate income, including (1) common stocks, (2) preferred stocks, including convertible securities, (3) master limited partnerships (“MLPs”) and (4) common shares of real estate investment trusts (“REITs”). The fund may also invest in fixed income securities of any maturity or credit quality, including high yield bonds rated below BBB by S&P or Fitch or Baa by Moody’s (commonly known as “junk bonds”). The fund invests without restriction as to issuer country, capitalization or currency.

Ranger International Management, LP (the “sub-adviser”) normally invests globally (including in emerging markets) in a variety of income-producing securities that the sub-adviser believes have attractive yields, and in the case of common stocks, the potential for dividend growth. The sub-adviser employs a bottom-up, fundamentals-based investment approach to security selection. The sub-adviser selects stock of issuers that it believes are stable and industry- or region-leading companies. The sub-adviser selects fixed income securities that it believes have the highest expected return among issuers of similar credit quality. The sub-adviser’s investment philosophy seeks domestic and international investment candidates characterized by (i) attractive yield, (ii) quality and (iii) financial strength.

The sub-adviser sells a security if the sub-adviser believes it is overvalued, more attractive candidates arise, or if there is a substantial, long term reduction in a company’s fundamental prospects that impair its value.

Under adverse or unstable market, economic or political conditions, the fund may take temporary defensive positions 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.

• Bank Obligations - To the extent the fund invests in U.S. bank obligations, the fund will be more susceptible to adverse events affecting the U.S. banking industry. Banks are sensitive to changes in money market and general economic conditions. Banks are highly regulated. Decisions by regulators may limit the loans banks make and the interest rates and fees they charge, and may reduce bank profitability.

• 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.

• Convertible Securities – Convertible securities share investment characteristics of both fixed income and equity securities. However, the value of these securities tends to vary more with fluctuations in the value of the underlying common stock than with fluctuations in interest rates. The value of convertible securities also tends to exhibit greater volatility than the underlying common stock. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The fund could lose money if the issuer of a convertible security is unable to meet its financial obligations or goes bankrupt.

• 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.

• Depositary Receipts – Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa. Such restrictions may cause equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

• 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.

• Fixed-Income Securities – The market prices of fixed-income securities may fall due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In addition, the market value of a fixed income security may decline if the issuer or other obligor of the security fails to pay principal and/or interest, otherwise defaults or has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines. When market prices fall, the value of your investment will go down. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

• 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.

• Growth Stocks – Returns on growth stocks may not move in tandem with returns on other categories of stocks or the market as a whole. Growth stocks may be particularly susceptible to larger price swings or to adverse developments. Growth stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors “value” stocks.

• High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk bonds,” are securities that are rated below “investment grade” (that is, securities rated below Baa/BBB) or, if unrated, determined to be below investment grade by the sub-adviser. Changes in interest rates, the market’s perception of the issuers and the creditworthiness of the issuers may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

• 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.

• Liquidity - Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

• 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.

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.

• Master Limited Partnership –Investments in MLPs involve risks that differ from investments in corporate issuers, including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP’s general partner, cash flow risks, dilution risks and risks related to the general partner’s right to require unitholders to sell their common units at an undesirable time or price.

• 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.

• Preferred Stock –Preferred stock’s right to dividends and liquidation proceeds is junior to the rights of a company’s debt securities.
