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. 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:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the fund’s sub-adviser, AQR Capital Management, LLC (the “sub-adviser”), pursues the fund’s investment objective by investing globally across a wide range of asset classes, including equities, fixed income, currencies and commodities. The fund may take both “long” and “short” positions in each of the asset classes through the use of certain derivative instruments as defined below. The fund has the flexibility to shift its allocation across asset classes and markets around the world, including emerging markets, based on the sub-adviser’s assessment of their relative attractiveness.

The fund obtains exposure to asset classes primarily through derivative instruments, such as forwards and futures contracts, options and swaps, including, but not limited to, global developed and emerging market equity index futures, swaps on equity index futures, equity swaps, options, global developed and emerging market currency forwards and futures, commodity futures and swaps, global developed fixed income futures, and bond and interest rate futures and swaps (collectively, the “Instruments”), either by investing directly in those Instruments, or indirectly by investing in a wholly-owned subsidiary of the fund organized as a company under the laws of the Cayman Islands (the “Subsidiary”) that invests in those Instruments. The fund may also invest in exchange traded funds or exchange traded notes. The fund may take a short position in an Instrument, such as a future, forward, or swap.

A significant portion of the fund’s assets may be invested directly or indirectly in short-term investments, which may include, but are not limited to, U.S. government securities, U.S. government agency securities, short-term fixed income securities, overnight and/or fixed term repurchase agreements, money market mutual fund shares, and cash and cash equivalents with one year or less term to maturity. These cash or cash equivalent holdings serve as collateral for the positions the fund takes and also earn income for the fund. While the fund normally does not engage in any direct borrowing, leverage is implicit in the futures and other derivatives it trades.

The fund generally intends to gain exposure to commodities by investing up to 25% of its total assets in the Subsidiary. The Subsidiary has the same investment objective as the fund and is advised by Transamerica Asset Management, Inc. and sub-advised by the sub-adviser. The Subsidiary, unlike the fund, may invest without limitation in commodities, commodity index-linked securities and other commodity-linked securities and derivative instruments, such as swaps and futures that provide exposure to the performance of the commodities markets. The Subsidiary may also invest in other instruments, including fixed income instruments, either as investments or to serve as margin or collateral for its derivative positions. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and is not subject to the investor protections of the 1940 Act.

The fund will allocate its assets among various regions and countries. Under normal market conditions, the fund invests at least 40% of its assets (or, if conditions are not favorable, at least 30% of its assets) outside of the U.S. through direct investments, the Instruments or depositary receipts (“Foreign Securities”). The fund’s portfolio normally will be composed of investments that are economically tied to no less than three different countries, including the United States.

Foreign Securities may include foreign currencies and interest rates, sovereign debt, equity indices representing countries other than the United States and through exposure to companies (i) organized or located outside the United States, (ii) whose primary trading market is located outside the United States or (iii) doing a substantial amount of business outside the United States, which the fund considers as a company that derives at least 50% of its revenue from business outside the United States or has at least 50% of its assets outside the United States.

The sub-adviser uses a bottom up systematic process that considers four primary indicators of attractiveness in determining whether to take a long and/or short position in an asset class through a direct investment or an Instrument: macroeconomic data, value, momentum, and carry.

Macroeconomic Data: The sub-adviser seeks to evaluate the impact of macroeconomic news and macroeconomic trends on the attractiveness of Instruments and asset classes around the world. Macroeconomic themes considered include, but are not limited to, business cycles, international trade, monetary policy, investor sentiment and asset-specific fundamentals.

The evaluation of macroeconomic attractiveness includes both quantitative and qualitative components.

Quantitative analysis measures an Instrument's attractiveness based on the current level and historical evolution of key macroeconomic measures. These measures include, but are not limited to, growth and inflation forecasts, demand for exports, central bank actions and equity market performance.

Qualitative input adds a perspective not available through quantitative analysis. These considerations include, but are not limited to, the sub-adviser's assessment of fiscal and monetary policy, trade policy, geo-political risks and supply-and-demand conditions.

Value: Value strategies favor investments that appear cheap over those that appear expensive based on fundamental measures related to price, seeking to capture the tendency for relatively cheap assets to outperform relatively expensive assets. The fund will seek to buy assets that are cheap and sell those that are expensive relative to similar investments globally and relative to their historical averages. Examples of value measures include using price-to-earnings and price-to-book ratios for selecting equities.

Momentum: Momentum strategies favor investments that have performed relatively well over those that have underperformed over the medium-term, seeking to capture the tendency that an asset’s recent performance will continue in the near future. The fund will seek to buy assets that recently outperformed and sell those that recently underperformed relative to similar investments globally and relative to their historical averages. Examples of momentum measures include simple price momentum for selecting equities and price- and yield-based momentum for selecting bonds.

Carry: Carry strategies favor investments with higher yields over those with lower yields, seeking to capture the tendency for higher-yielding assets to provide higher returns than lower-yielding assets. The fund will seek to buy high-yielding assets and sell low-yielding assets relative to similar investments globally and relative to their historical averages. An example of carry measures includes using interest rates to select currencies and bonds.

The fund is non-diversified.

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 fund may take temporary defensive positions; in such a case, the fund will not be pursuing its principal investment strategies. The following is a summary description of principal risks (in alphabetical order) of investing in the fund (either directly or through its investments in underlying funds, including the Subsidiary). 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.

Aggressive Investment – The fund's investment strategies, techniques and/or portfolio investments differ from those of many other mutual funds and may be considered aggressive. This approach to investing may expose the fund to additional risks, make the fund a more volatile investment than other mutual funds and cause the fund to perform less favorably than other mutual funds under similar market or economic conditions.

CFTC Regulation – The Investment Adviser has registered as a "commodity pool operator" under the Commodity Exchange Act with respect to its service as investment adviser to the fund. The Investment Adviser is therefore subject to dual regulation by the SEC and the Commodity Futures Trading Commission ("CFTC"), and is a member of the National Futures Association and is also subject to its rules. Regulation of commodity investing continues to change, and additional compliance and other expenses may be incurred.

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.

Counterparty – The fund will be subject to credit risk (that is, where changes in an issuer's financial strength or credit rating may affect an instrument's value) with respect to the amount it expects to receive from counterparties to derivatives, repurchase agreements and other financial contracts entered into by the fund or held by special purpose or structured vehicles. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the value of your investment in the fund may decline.

Credit – If an issuer or other obligor (such as a party providing insurance or other credit enhancement) 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 value of any underlying assets declines, the value of your investment will typically decline. Below investment grade, high-yield debt securities (commonly known as "junk bonds") have a higher risk of 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 investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could reduce or eliminate investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, 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.

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 derivatives 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. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The U.S. government is in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make them more costly, may limit their availability, may disrupt markets 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 investments risks. These risks are greater for investments in issuers in emerging market countries. Emerging market countries tend to have economic, political and legal systems that are less fully developed and are less stable than those of more developed countries. Emerging market securities are often particularly sensitive to market movements because their market prices tend to reflect speculative expectations. 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.

Exchange Traded Funds (ETFs) – 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.

Exchange-Traded Notes – Exchange-Traded Notes ("ETNs") are a type of unsecured, unsubordinated debt security that have characteristics and risks similar to those of fixed-income securities and trade on a major exchange similar to shares of ETFs. They differ from other types of bonds and notes because ETN returns are based upon the performance of a reference asset or benchmark minus applicable fees, no period coupon payments are distributed and no principal protections exist. The value of an ETN may be influenced by, among other things, time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying market, changes in the applicable interest rates and changes in the issuer's credit rating.

Extension – When interest rates rise, repayments of fixed income securities, particularly asset- and mortgage-backed securities, may occur more slowly than anticipated, extending the effective duration of these fixed income securities at below market interest rates and causing their market prices to decline more than they would have declined due to the rise in interest rates alone. This may cause the fund's share price to be more volatile.

Fixed-Income Securities – The market prices of fixed-income securities may go up or down, sometimes rapidly and unpredictably, 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. The value of your investment will generally go down when interest rates rise. Interest rates have been at historically low levels, so the fund faces a heightened risk that interest rates may rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

Foreign Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries in which the fund may invest may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the fund's investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, political or financial instability or other adverse economic or political developments. Lack of information and weaker accounting standards also may affect the value of these securities.

Forwards and Futures Contracts –The successful use of forward and futures contracts draws upon the sub-adviser's skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of forward and futures contracts, which may adversely affect the fund's NAV and total return, are (a) the imperfect correlation between the change in market value of the instruments held by the fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the sub-adviser's inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the fund may have to sell securities at a time when it may be disadvantageous to do so.

Interest Rate – Interest rates in the U.S. have been at historically low levels, so the fund faces a heightened risk that interest rates may rise. The value of fixed income securities generally goes down when interest rates rise, and therefore the value of your investment in the fund may also go down. 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.

Investment Companies – To the extent that the fund invests in other investment companies, such as closed-end or exchange-traded funds, it is subject to the risks of these investment companies and bears its pro rata share of the investment companies' expenses.

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 use of leverage is considered to be a speculative investment practice and may result in the loss of a substantial amount, and possibly all, of the fund's assets. The fund also may have to sell assets at inopportune times to satisfy its obligations.

Liquidity – The fund may make investments that are illiquid or that become illiquid after purchase. The liquidity and value of investments can deteriorate rapidly and those investments may be difficult or impossible to sell, particularly during times of market turmoil. These illiquid investments may also be difficult to value. If the fund is forced to sell an illiquid investment to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

Manager – The fund is subject to the risk that the sub-adviser's judgments and investment decisions, as well as the methods, tools, resources, information and data, and the analyses employed or relied on by the sub-adviser to make those judgments and decisions may be incorrect or otherwise 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 up or 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. Financial markets in the U.S., Europe and elsewhere have experienced increased volatility and decreased liquidity since the global financial crisis began in 2008. Governmental and non-governmental issuers defaulted on, or were forced to restructure, their debts. These market conditions may continue, worsen or spread. The U.S. government and the Federal Reserve, as well as certain foreign governments and their central banks have taken steps to support financial markets, including keeping interest rates at historically low levels. More recently, the Federal Reserve has reduced its market support activities. Further reduction or withdrawal of this support, or other related efforts in response to the crisis could negatively affect financial markets generally and increase market volatility as well as result in higher interest rates and reduce the value and liquidity of certain securities. This environment could make identifying investment risks and opportunities especially difficult for the sub-adviser. Whether or not the fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the fund's investments may be negatively affected. In addition, policy and legislative changes in the United States and in other countries are affecting many aspects of financial regulation, and in some instances may contribute to decreased liquidity and increased volatility in the financial markets.

Model and Data – If quantitative models, algorithms or calculations (whether proprietary and developed by the sub-adviser or supplied by third parties) ("Models") or information or data supplied by third parties ("Data") prove to be incorrect or incomplete, any decisions made, in whole or part, in reliance thereon expose the fund to additional risks. Models can be predictive in nature. The use of predictive Models has inherent risks. The success of relying on or otherwise using Models depends on a number of factors, including the validity, accuracy and completeness of the Model's development, implementation and maintenance, the Model's assumptions, factors, algorithms and methodologies, and the accuracy and reliability of the supplied historical or other Data. Models rely on, among other things, correct and complete Data inputs. If incorrect Data is entered into even a well-founded Model, the resulting information will be incorrect. However, even if Data is input correctly, Model prices may differ substantially from market prices, especially for securities with complex characteristics. Investments selected with the use of Models may perform differently than expected as a result of the design of the Model, inputs into the Model or other factors. There can be no assurance that the use of Models will result in effective investment decisions for the fund.

New Fund – The fund is newly formed. Investors in the fund bear the risk that the sub-adviser may not be successful in implementing its investment strategy, and may not employ a successful investment strategy, or that the fund may fail to attract sufficient assets under management to realize economies of scale, any of which could result in the fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders.

Non-Diversification – The fund is classified as "non-diversified," which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent the fund invests its assets in a smaller number of issuers, the fund will be more susceptible to negative events affecting those issuers than a diversified fund.

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 not benefit from the rise in market price that normally accompanies a decline in interest rates, and 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.

Short Sales – A short sale may be effected by selling a security that the fund does not own. If the price of the security sold short increases, the fund would incur a loss; conversely, if the price declines, the fund will realize a gain. Although the gain is limited by the price at which the security was sold short, the loss is potentially unlimited. The fund may also pay transaction costs and borrowing fees in connection with short sales.

Subsidiary – By investing in the Subsidiary, the fund will be indirectly exposed to the risks associated with the Subsidiary's investments. The derivatives and other investments that will be held by the Subsidiary are generally similar to those that are permitted to be held by the fund and will be subject to the same risks that apply to similar investments if held directly by the fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act, and, unless otherwise noted in this prospectus, is not subject to the investor protections of the Investment Company Act. Although certain regulated investment companies received private letter rulings from the Internal Revenue Service (“IRS”) with respect to their investment in entities similar to the Subsidiary, the fund has not received such a ruling. The IRS is no longer issuing private letter rulings on structures of this kind and is reportedly reexamining its position with respect to such structures. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the fund and/or the Subsidiary to operate as described in this prospectus and the SAI and could adversely affect the fund.

Tax – The fund may seek to gain exposure to the commodity markets primarily through investments in commodity-linked notes and through investments in the Subsidiary. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the fund's investments in the Subsidiary may be adversely affected by future legislation, Treasury Regulations and/or guidance issued by the IRS that could, among other things, affect the character, timing and/or amount of the fund's taxable income or gains and of distributions made by the fund.

U.S. Government Agency Obligations – Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. government that are supported by the full faith and credit of the U.S. generally present a lesser degree of credit risk than securities issued by agencies and instrumentalities sponsored by the U.S. government that are supported only by the issuer's right to borrow from the U.S. Treasury and securities issued by agencies and instrumentalities sponsored by the U.S. government that are supported only by the credit of the issuing agencies. Although the U.S. government has provided financial support to the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac") in the past, there can be no assurance that it will support these or other government sponsored entities in the future.

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, that are priced based upon valuations provided by third-party pricing services that use matrix or evaluated pricing systems, or that are valued using a fair value methodology.

Value Investing – The prices of securities the sub-adviser believes are undervalued may not appreciate as anticipated or may go down. Value 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 "growth" stocks.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification – The fund is classified as "non-diversified," which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent the fund invests its assets in a smaller number of issuers, the fund will be more susceptible to negative events affecting those issuers than a diversified fund.
