Class I2 | Transamerica Floating Rate

TRANSAMERICA FLOATING RATE

Investment Objective:

Seeks to achieve a high level of current income

with capital appreciation as a secondary objective.

Fees and Expenses:

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

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

Annual Fund Operating Expenses		Class I2 Transamerica Floating Rate I2
Management fees		0.61%
Distribution and service (12b-1) fees		none
Other expenses	[1]	0.75%
Total annual fund operating expenses		1.36%
Fee waiver and/or expense reimbursement	[2]	0.56%
Total annual fund operating expenses after fee waiver and/or expense reimbursement		0.80%

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:

Expense Example (USD $)	1 year	3 years
Class I2 Transamerica Floating Rate I2	82	376

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.

Portfolio turnover rate is not included at this time because the fund did not commence operations until after the most recent fiscal year-end.

Principal Investment Strategies:

Under normal circumstances the fund's sub-adviser, Aegon USA Investment Management, LLC ("AUIM") seeks to achieve the fund's objective by investing at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in floating rate loans and floating rate debt securities. Floating rate loans have interest rates that reset periodically, typically quarterly or monthly. Interest rates on floating rate loans are generally based off the London Interbank Offered Rate ("LIBOR") plus a premium, but certain leveraged loans can use different base rates. Floating rate loans represent amounts borrowed by companies or other entities, the debt securities of which are usually rated below investment grade, from banks and other lenders. In many cases, they are issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancings. Certain loans in which the fund invests are referred to as "leveraged loans" because the borrowing companies have significantly more debt than equity.

The sub-adviser selects investments based on fundamentals, sentiment and positioning, technicals and valuations. Analysis covers all aspects of the investment including underlying credit, capital structure, collateral and covenants. Comprehensive understanding of the entire competitive landscape supports strategic positioning of a credit, and allows for more effective measurement of up and downside scenarios. Individual credits are analyzed as both an independent holding and at the portfolio level. An overlay of top-down economic, business cycle and sector trend analysis is applied to investment candidates.

The fund will primarily invest in first lien, senior secured term loans ("senior loans") to corporate issuers, partnerships and other entities. The fund can invest in senior loans of any maturity and quality. The majority of the fund's assets will be invested in below-investment grade loans and "high-yield" securities (commonly known as "junk bonds") and the fund may invest without limitation in such loans and securities. To a lesser extent the fund will invest in unsecured senior loans, unsecured floating rate notes, second lien loans and subordinated bridge loans ("junior loans"), unsecured fixed rate high yield bonds, other floating rate debt securities, fixed income debt obligations, money market instruments, and other debt securities, including distressed securities that may be in default and have any or no credit rating. The fund can invest up to 15% of its assets in loans and securities that are not secured by any specific collateral. The fund can invest up to 15% in unsecured fixed rate high-yield bonds and 15% in second lien loans. The fund may invest in loans of foreign-domiciled borrowers and foreign debt securities, including emerging market debt securities, but expects that the majority of assets in which it invests will be invested in loans and securities of U.S. borrowers or issuers. The fund may invest in derivatives such as futures, forwards, and options for a variety of purposes, including as a means to manage fixed income exposure and to increase the fund's return as a non-hedging strategy that may be considered speculative. The fund can invest in leverage loan exchange traded funds ("ETF") to create exposure to the asset class.

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 – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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. Below investment grade, high-yield debt securities (commonly known as "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.

• 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.

• Distressed or Defaulted Securities – Investments in defaulted securities and obligations of distressed issuers, including securities that are, or may be, involved in reorganizations or other financial restructurings, either out of court or in bankruptcy, involve substantial risks and are considered speculative. The fund may suffer significant losses if the reorganization or restructuring is not completed as anticipated. The fund will generally not receive interest payments on the distressed securities and may incur costs to protect its investment. Repayment of defaulted securities and obligations of distressed issuers is subject to significant uncertainties.

• 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. Low trading volumes may result in a lack of liquidity and in extreme price volatility.

• Exchange Traded Funds – 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.

• 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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.

• 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. Interest rates in the U.S. have recently been historically low. 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.

• Junior Loans – Junior loans are subject to the same general risks inherent to any loan investment, including credit risk, market and liquidity risk and interest rate risk. Due to their lower place in the borrower's capital structure and possible unsecured status, junior loans involve a higher degree of overall risk than senior loans of the same borrower.

• 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.

• Loans – Loans are subject to the credit risk of nonpayment of principal or interest. Economic downturns or increases in interest rates may cause an increase in defaults, interest rate risk and liquidity risk. Loans may or may not be collateralized at the time of acquisition, and any collateral may be relatively illiquid or lose all or substantially all of its value subsequent to investment. In the event of bankruptcy of a borrower, the fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a loan. The fund's investments in loans are also subject to prepayment or call risk.

• 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

• New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment Adviser and/or 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.

• 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.

• 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, 2014, to waive fees and/or reimburse fund expenses to the extent that the fund's total operating expenses exceed 0.80%, 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. These arrangements cannot be terminated prior to October 31, 2014 without the Board of Trustees' consent. 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.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies:
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The fund normally invests primarily in stocks of medium sized companies which the fund's sub-adviser believes have the potential to deliver earnings growth in excess of the market average, or to become market leaders. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in securities of medium sized (or mid-cap) companies and other investments with similar economic characteristics. The fund considers mid-cap companies to be companies with market capitalizations that, at the time of initial purchase, are within the range of capitalization of the companies that are included in the Russell Midcap® Growth Index1. As of June 30, 2013, the market capitalizations of companies in the Russell Midcap® Growth Index ranged from approximately $1.7 billion to $27.7 billion. Over time, the capitalizations of the companies in the Russell Midcap® Growth Index will change. As they do, the size of the companies in which the fund invests may change. The fund's equity securities may include common stocks and preferred stocks listed on the New York Stock Exchange and on other national securities exchanges and, to a lesser extent, stocks that are traded over-the-counter. The fund emphasizes common stocks. The fund may also invest in foreign securities. The fund may also invest its assets in cash, cash equivalent securities or short-term debt securities, repurchase agreements and money market instruments. Generally, 5% or less of fund assets will be invested in cash and cash equivalents. 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. 1 Russell Investment Group is the source and owner of the trademarks, service marks and copyrights related to the Russell indexes.

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. Cash Management and Defensive Investing – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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 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, 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. 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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. 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. 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time. Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of medium capitalization companies. Investing in medium capitalization companies involves greater risk than is customarily associated with more established companies. The prices of securities of medium capitalization companies generally are more volatile and are more likely to be adversely affected by changes in earnings results and investor expectations or poor economic or market conditions. Securities of medium capitalization companies may underperform larger capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses. New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment Adviser and/or 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. 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.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies:
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The fund normally invests primarily in stocks of companies with small market capitalizations which, in the opinion of the fund's sub-adviser, present an opportunity for significant increases in value, without consideration for current income. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of companies with small market capitalizations (or small-cap companies) and other investments with similar economic characteristics. The fund considers small-cap companies to be companies with market capitalizations that, at the time of initial purchase, are within the range of capitalization of the companies that are included in the Russell 2000® Index1 over time. As of June 30, 2013, the market capitalizations of companies in the Russell 2000® Index ranged from $22.5 million to $5.9 billion. Over time, the capitalizations of the companies in the Russell 2000® Index will change. As they do, the size of the companies in which the fund invests may change. The fund may invest in ADRs and/or foreign securities trading on U.S. exchanges, which generally stay under 10% of portfolio assets. It will not trade securities on a non-U.S. exchange. Investment in derivatives, futures and swaps are not permitted. The fund may also invest its assets in cash, cash equivalent securities or short-term debt securities, repurchase agreements and money market instruments. Generally, 5% or less of fund assets will be invested in cash and cash equivalents. 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. 1 Russell Investment Group is the source and owner of the trademarks, service marks and copyrights related to the Russell indexes.

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. Cash Management and Defensive Investing – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not achieve its objective. 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. 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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. 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. 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time. 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. 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. 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. 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.

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.

Portfolio turnover rate is not included at this time because the fund did not commence operations until after the most recent fiscal year-end.

Principal Investment Strategies:

The fund normally invests primarily in stocks of medium sized companies which the fund's sub-adviser believes have the potential to deliver earnings growth in excess of the market average, or to become market leaders. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in securities of medium sized (or mid-cap) companies and other investments with similar economic characteristics. The fund considers mid-cap companies to be companies with market capitalizations that, at the time of initial purchase, are within the range of capitalization of the companies that are included in the Russell Midcap^® Growth Index¹. As of June 30, 2013, the market capitalizations of companies in the Russell Midcap^® Growth Index ranged from approximately $1.7 billion to $27.7 billion. Over time, the capitalizations of the companies in the Russell Midcap^® Growth Index will change. As they do, the size of the companies in which the fund invests may change.

The fund's equity securities may include common stocks and preferred stocks listed on the New York Stock Exchange and on other national securities exchanges and, to a lesser extent, stocks that are traded over-the-counter. The fund emphasizes common stocks. The fund may also invest in foreign securities.

The fund may also invest its assets in cash, cash equivalent securities or short-term debt securities, repurchase agreements and money market instruments. Generally, 5% or less of fund assets will be invested in cash and cash equivalents.

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 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.

To the extent that the fund's assets are used for cash management or defensive investing purposes, it may not 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 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, 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.

• 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.

In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

• Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of medium capitalization companies. Investing in medium capitalization companies involves greater risk than is customarily associated with more established companies. The prices of securities of medium capitalization companies generally are more volatile and are more likely to be adversely affected by changes in earnings results and investor expectations or poor economic or market conditions. Securities of medium capitalization companies may underperform larger capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

• 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.

• 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.

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 rate is not included at this time because the fund did not commence operations until after the most recent fiscal year-end.

Principal Investment Strategies:

The fund seeks to achieve its objective by primarily investing in the common stock of closed-end funds selected by Transamerica Asset Management, Inc. ("TAM"). The fund seeks to identify and exploit relative value opportunities in the closed-end fund universe. The overall investment philosophy is predicated on recognizing and capitalizing on market inefficiencies found in this universe.

The combination of TAM's quantitative approach and research-driven process for selecting closed-end funds is intended to produce a portfolio focused on total return that is allocated across multiple sectors, strategies and managers. The fund's available investment universe is initially composed of those exchange-listed closed-end funds, which may include both foreign and domestic securities of all ratings and market capitalizations, with greater than $350 million in market capitalization and an average daily volume greater than $1 million. From this investment universe, TAM seeks to identify closed-end funds that are trading at a discount larger than the respective universe average, but are exhibiting signs of price appreciation.

From the filtered universe of closed-end funds, TAM constructs the portfolio by utilizing a value investment approach that seeks to identify investment worthy ideas. TAM normally selects the combination of underlying closed-end funds in an effort to maximize the diversification of independent sources of risk. The allocation to a single underlying closed-end fund will generally not exceed 3%.

The fund may also invest in exchange traded funds ("ETFs") in order to provide exposure to asset classes that are unavailable in the closed-end universe, and to provide additional sources of liquidity. Under normal market conditions, ETFs are not expected to comprise more than 20% of the fund's assets.

The fund may have exposure to derivative instruments, such as options, futures, or forward contracts and swaps through its investment in the underlying closed-end funds and ETFs.

The fund may also seek to earn a liquidity premium through its underlying closed-end fund investments by buying underlying closed-end funds when they are less liquid and selling them when they are more liquid.

Each underlying closed-end fund and ETF has its own investment objective, principal investment strategies, and risk.

It is not possible to predict the extent to which the fund will be invested in particular underlying closed-end funds at any time. The fund may be a significant shareholder in certain underlying closed-end funds, given the fund's planned investments in certain underlying closed-end funds, the fund considers multiple investments of up to 3% to be significant and, as such, the fund to be a "significant shareholder" of those underlying closed-end funds. TAM may change the fund's asset allocations and underlying closed-end funds at any time without notice to the shareholders and without shareholder approval.

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.

The fund may also invest in cash when TAM is unable to identify attractive investment opportunities that meet the fund's investment criteria.

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 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 – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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. Below investment grade, high-yield debt securities (commonly known as “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 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, 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.

• 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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.

• 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. Interest rates in the U.S. have recently been historically low. 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 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 adviser 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

• New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment 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.

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

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

• Underlying Closed-end Funds and Exchange Traded Funds – Because the fund invests its assets in various underlying closed-end funds and ETFs (the “underlying funds”), its ability to achieve its investment objective depends largely on the performance of the underlying funds in which it invests. Each of the underlying funds in which the fund may invest has its own investment risks, and those risks can affect the value of the underlying funds' shares and therefore the value of the fund's investments. There can be no assurance that the investment objective of any underlying fund will be achieved. To the extent that the fund invests more of its assets in one underlying fund than in another, the fund will have greater exposure to the risks of that underlying fund. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying funds 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 or closed-end fund 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 a closed-end fund or an ETF can fluctuate up and down, and the fund could lose money investing in such a closed-end fund or an ETF if the prices of the securities owned by the closed-end fund or ETF go down. In addition, closed-end funds and ETFs are subject to the following risks that do not apply to conventional funds: (i) the market price of a closed-end fund’s or an ETF’s shares may be above or below the shares’ net asset value (shares of closed-end funds frequently trade at a discount from their net asset value); (ii) an active trading market for a closed-end fund’s or an ETF’s shares may not develop or be maintained; or (iii) trading of a closed-end fund’s or 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. Closed-end funds and ETFs may employ leverage, which also subjects the funds to increased risks such as increased volatility.

• 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 and acquired fund fees and 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, 2014, to waive fees and/or reimburse fund expenses to the extent that the fund's total operating expenses exceed 0.95%, 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. These arrangements cannot be terminated prior to October 31, 2014 without the Board of Trustees' consent. 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.

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 Retail Class Transamerica Floating Rate (USD $)	1 year	3 years
A	582	923
C	286	794
I	82	399

If the shares are not redeemed:

Expense Example, No Redemption Retail Class Transamerica Floating Rate (USD $)	1 year	3 years
A	582	923
C	183	685
I	82	399

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.

Portfolio turnover rate is not included at this time because the fund did not commence operations until after the most recent fiscal year-end.

Principal Investment Strategies:

Under normal circumstances the fund's sub-adviser, Aegon USA Investment Management, LLC ("AUIM") seeks to achieve the fund's objective by investing at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in floating rate loans and floating rate debt securities. Floating rate loans have interest rates that reset periodically, typically quarterly or monthly. Interest rates on floating rate loans are generally based off the London Interbank Offered Rate ("LIBOR") plus a premium, but certain leveraged loans can use different base rates. Floating rate loans represent amounts borrowed by companies or other entities, the debt securities of which are usually rated below investment grade, from banks and other lenders. In many cases, they are issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancings. Certain loans in which the fund invests are referred to as "leveraged loans" because the borrowing companies have significantly more debt than equity.

The sub-adviser selects investments based on fundamentals, sentiment and positioning, technicals and valuations. Analysis covers all aspects of the investment including underlying credit, capital structure, collateral and covenants. Comprehensive understanding of the entire competitive landscape supports strategic positioning of a credit, and allows for more effective measurement of up and downside scenarios. Individual credits are analyzed as both an independent holding and at the portfolio level. An overlay of top-down economic, business cycle and sector trend analysis is applied to investment candidates.

The fund will primarily invest in first lien, senior secured term loans ("senior loans") to corporate issuers, partnerships and other entities. The fund can invest in senior loans of any maturity and quality. The majority of the fund's assets will be invested in below-investment grade loans and "high-yield" securities (commonly known as "junk bonds") and the fund may invest without limitation in such loans and securities. To a lesser extent the fund will invest in unsecured senior loans, unsecured floating rate notes, second lien loans and subordinated bridge loans ("junior loans"), unsecured fixed rate high yield bonds, other floating rate debt securities, fixed income debt obligations, money market instruments, and other debt securities, including distressed securities that may be in default and have any or no credit rating. The fund can invest up to 15% of its assets in loans and securities that are not secured by any specific collateral. The fund can invest up to 15% in unsecured fixed rate high-yield bonds and 15% in second lien loans. The fund may invest in loans of foreign-domiciled borrowers and foreign debt securities, including emerging market debt securities, but expects that the majority of assets in which it invests will be invested in loans and securities of U.S. borrowers or issuers. The fund may invest in derivatives such as futures, forwards, and options for a variety of purposes, including as a means to manage fixed income exposure and to increase the fund's return as a non-hedging strategy that may be considered speculative. The fund can invest in leverage loan exchange traded funds ("ETF") to create exposure to the asset class.

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 – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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. Below investment grade, high-yield debt securities (commonly known as "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.

• 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.

• Distressed or Defaulted Securities – Investments in defaulted securities and obligations of distressed issuers, including securities that are, or may be, involved in reorganizations or other financial restructurings, either out of court or in bankruptcy, involve substantial risks and are considered speculative. The fund may suffer significant losses if the reorganization or restructuring is not completed as anticipated. The fund will generally not receive interest payments on the distressed securities and may incur costs to protect its investment. Repayment of defaulted securities and obligations of distressed issuers is subject to significant uncertainties.

• 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. Low trading volumes may result in a lack of liquidity and in extreme price volatility.

• Exchange Traded Funds – 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.

• 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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.

• 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. Interest rates in the U.S. have recently been historically low. 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.

• Junior Loans – Junior loans are subject to the same general risks inherent to any loan investment, including credit risk, market and liquidity risk and interest rate risk. Due to their lower place in the borrower's capital structure and possible unsecured status, junior loans involve a higher degree of overall risk than senior loans of the same borrower.

• 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.

• Loans – Loans are subject to the credit risk of nonpayment of principal or interest. Economic downturns or increases in interest rates may cause an increase in defaults, interest rate risk and liquidity risk. Loans may or may not be collateralized at the time of acquisition, and any collateral may be relatively illiquid or lose all or substantially all of its value subsequent to investment. In the event of bankruptcy of a borrower, the fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a loan. The fund's investments in loans are also subject to prepayment or call risk.

• 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

• 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.

• 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.

• 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	Under normal circumstances the fund's sub-adviser, Aegon USA Investment Management, LLC ("AUIM") seeks to achieve the fund's objective by investing at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in floating rate loans and floating rate debt securities. Floating rate loans have interest rates that reset periodically, typically quarterly or monthly. Interest rates on floating rate loans are generally based off the London Interbank Offered Rate ("LIBOR") plus a premium, but certain leveraged loans can use different base rates. Floating rate loans represent amounts borrowed by companies or other entities, the debt securities of which are usually rated below investment grade, from banks and other lenders. In many cases, they are issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancings. Certain loans in which the fund invests are referred to as "leveraged loans" because the borrowing companies have significantly more debt than equity. The sub-adviser selects investments based on fundamentals, sentiment and positioning, technicals and valuations. Analysis covers all aspects of the investment including underlying credit, capital structure, collateral and covenants. Comprehensive understanding of the entire competitive landscape supports strategic positioning of a credit, and allows for more effective measurement of up and downside scenarios. Individual credits are analyzed as both an independent holding and at the portfolio level. An overlay of top-down economic, business cycle and sector trend analysis is applied to investment candidates. The fund will primarily invest in first lien, senior secured term loans ("senior loans") to corporate issuers, partnerships and other entities. The fund can invest in senior loans of any maturity and quality. The majority of the fund's assets will be invested in below-investment grade loans and "high-yield" securities (commonly known as "junk bonds") and the fund may invest without limitation in such loans and securities. To a lesser extent the fund will invest in unsecured senior loans, unsecured floating rate notes, second lien loans and subordinated bridge loans ("junior loans"), unsecured fixed rate high yield bonds, other floating rate debt securities, fixed income debt obligations, money market instruments, and other debt securities, including distressed securities that may be in default and have any or no credit rating. The fund can invest up to 15% of its assets in loans and securities that are not secured by any specific collateral. The fund can invest up to 15% in unsecured fixed rate high-yield bonds and 15% in second lien loans. The fund may invest in loans of foreign-domiciled borrowers and foreign debt securities, including emerging market debt securities, but expects that the majority of assets in which it invests will be invested in loans and securities of U.S. borrowers or issuers. The fund may invest in derivatives such as futures, forwards, and options for a variety of purposes, including as a means to manage fixed income exposure and to increase the fund's return as a non-hedging strategy that may be considered speculative. The fund can invest in leverage loan exchange traded funds ("ETF") to create exposure to the asset class. 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 – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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. Below investment grade, high-yield debt securities (commonly known as "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. 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. Distressed or Defaulted Securities – Investments in defaulted securities and obligations of distressed issuers, including securities that are, or may be, involved in reorganizations or other financial restructurings, either out of court or in bankruptcy, involve substantial risks and are considered speculative. The fund may suffer significant losses if the reorganization or restructuring is not completed as anticipated. The fund will generally not receive interest payments on the distressed securities and may incur costs to protect its investment. Repayment of defaulted securities and obligations of distressed issuers is subject to significant uncertainties. 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. Low trading volumes may result in a lack of liquidity and in extreme price volatility. Exchange Traded Funds – 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. 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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. 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. Interest rates in the U.S. have recently been historically low. 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. Junior Loans – Junior loans are subject to the same general risks inherent to any loan investment, including credit risk, market and liquidity risk and interest rate risk. Due to their lower place in the borrower's capital structure and possible unsecured status, junior loans involve a higher degree of overall risk than senior loans of the same borrower. 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. Loans – Loans are subject to the credit risk of nonpayment of principal or interest. Economic downturns or increases in interest rates may cause an increase in defaults, interest rate risk and liquidity risk. Loans may or may not be collateralized at the time of acquisition, and any collateral may be relatively illiquid or lose all or substantially all of its value subsequent to investment. In the event of bankruptcy of a borrower, the fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a loan. The fund's investments in loans are also subject to prepayment or call risk. 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time. New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment Adviser and/or 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. 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. 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.

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 [Heading]	rr_StrategyHeading	Principal Investment Strategies:
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The fund normally invests primarily in stocks of companies with small market capitalizations which, in the opinion of the fund's sub-adviser, present an opportunity for significant increases in value, without consideration for current income. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of companies with small market capitalizations (or small-cap companies) and other investments with similar economic characteristics. The fund considers small-cap companies to be companies with market capitalizations that, at the time of initial purchase, are within the range of capitalization of the companies that are included in the Russell 2000® Index1 over time. As of June 30, 2013, the market capitalizations of companies in the Russell 2000® Index ranged from $22.5 million to $5.9 billion. Over time, the capitalizations of the companies in the Russell 2000® Index will change. As they do, the size of the companies in which the fund invests may change. The fund may invest in ADRs and/or foreign securities trading on U.S. exchanges, which generally stay under 10% of portfolio assets. It will not trade securities on a non-U.S. exchange. Investment in derivatives, futures and swaps are not permitted. The fund may also invest its assets in cash, cash equivalent securities or short-term debt securities, repurchase agreements and money market instruments. Generally, 5% or less of fund assets will be invested in cash and cash equivalents. 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. 1 Russell Investment Group is the source and owner of the trademarks, service marks and copyrights related to the Russell indexes.

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. Cash Management and Defensive Investing – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not achieve its objective. 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. 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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. 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. 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time. New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment Adviser and/or 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. 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. 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. 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.

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:

Expense Example (USD $)	1 year	3 years
Class I2 Transamerica Small Cap Core I2	90	281

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.

Portfolio turnover rate is not included at this time because the fund did not commence operations until after the most recent fiscal year-end.

Principal Investment Strategies:

The fund normally invests primarily in stocks of companies with small market capitalizations which, in the opinion of the fund's sub-adviser, present an opportunity for significant increases in value, without consideration for current income. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of companies with small market capitalizations (or small-cap companies) and other investments with similar economic characteristics. The fund considers small-cap companies to be companies with market capitalizations that, at the time of initial purchase, are within the range of capitalization of the companies that are included in the Russell 2000^® Index¹ over time. As of June 30, 2013, the market capitalizations of companies in the Russell 2000^® Index ranged from $22.5 million to $5.9 billion. Over time, the capitalizations of the companies in the Russell 2000^® Index will change. As they do, the size of the companies in which the fund invests may change.

The fund may invest in ADRs and/or foreign securities trading on U.S. exchanges, which generally stay under 10% of portfolio assets. It will not trade securities on a non-U.S. exchange. Investment in derivatives, futures and swaps are not permitted.

The fund may also invest its assets in cash, cash equivalent securities or short-term debt securities, repurchase agreements and money market instruments. Generally, 5% or less of fund assets will be invested in cash and cash equivalents.

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.

• Cash Management and Defensive Investing – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not achieve its objective.

• 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.

• 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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.

• 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.

• 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

• New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment Adviser and/or 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.

• 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.

• 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.

• 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.

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.

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 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, 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. 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.

Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of medium capitalization companies. Investing in medium capitalization companies involves greater risk than is customarily associated with more established companies. The prices of securities of medium capitalization companies generally are more volatile and are more likely to be adversely affected by changes in earnings results and investor expectations or poor economic or market conditions. Securities of medium capitalization companies may underperform larger capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

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.

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).

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 year	3 years
Class I2 Transamerica Mid Cap Growth I2	82	255

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.

Portfolio turnover rate is not included at this time because the fund did not commence operations until after the most recent fiscal year-end.

Principal Investment Strategies:

The fund normally invests primarily in stocks of medium sized companies which the fund's sub-adviser believes have the potential to deliver earnings growth in excess of the market average, or to become market leaders. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in securities of medium sized (or mid-cap) companies and other investments with similar economic characteristics. The fund considers mid-cap companies to be companies with market capitalizations that, at the time of initial purchase, are within the range of capitalization of the companies that are included in the Russell Midcap^® Growth Index¹. As of June 30, 2013, the market capitalizations of companies in the Russell Midcap^® Growth Index ranged from approximately $1.7 billion to $27.7 billion. Over time, the capitalizations of the companies in the Russell Midcap^® Growth Index will change. As they do, the size of the companies in which the fund invests may change.

The fund's equity securities may include common stocks and preferred stocks listed on the New York Stock Exchange and on other national securities exchanges and, to a lesser extent, stocks that are traded over-the-counter. The fund emphasizes common stocks. The fund may also invest in foreign securities.

The fund may also invest its assets in cash, cash equivalent securities or short-term debt securities, repurchase agreements and money market instruments. Generally, 5% or less of fund assets will be invested in cash and cash equivalents.

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.

• Cash Management and Defensive Investing – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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 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, 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.

• 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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.

• 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.

• 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

• Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of medium capitalization companies. Investing in medium capitalization companies involves greater risk than is customarily associated with more established companies. The prices of securities of medium capitalization companies generally are more volatile and are more likely to be adversely affected by changes in earnings results and investor expectations or poor economic or market conditions. Securities of medium capitalization companies may underperform larger capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

• New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment Adviser and/or 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.

• 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.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies:
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances the fund's sub-adviser, Aegon USA Investment Management, LLC ("AUIM") seeks to achieve the fund's objective by investing at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in floating rate loans and floating rate debt securities. Floating rate loans have interest rates that reset periodically, typically quarterly or monthly. Interest rates on floating rate loans are generally based off the London Interbank Offered Rate ("LIBOR") plus a premium, but certain leveraged loans can use different base rates. Floating rate loans represent amounts borrowed by companies or other entities, the debt securities of which are usually rated below investment grade, from banks and other lenders. In many cases, they are issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancings. Certain loans in which the fund invests are referred to as "leveraged loans" because the borrowing companies have significantly more debt than equity. The sub-adviser selects investments based on fundamentals, sentiment and positioning, technicals and valuations. Analysis covers all aspects of the investment including underlying credit, capital structure, collateral and covenants. Comprehensive understanding of the entire competitive landscape supports strategic positioning of a credit, and allows for more effective measurement of up and downside scenarios. Individual credits are analyzed as both an independent holding and at the portfolio level. An overlay of top-down economic, business cycle and sector trend analysis is applied to investment candidates. The fund will primarily invest in first lien, senior secured term loans ("senior loans") to corporate issuers, partnerships and other entities. The fund can invest in senior loans of any maturity and quality. The majority of the fund's assets will be invested in below-investment grade loans and "high-yield" securities (commonly known as "junk bonds") and the fund may invest without limitation in such loans and securities. To a lesser extent the fund will invest in unsecured senior loans, unsecured floating rate notes, second lien loans and subordinated bridge loans ("junior loans"), unsecured fixed rate high yield bonds, other floating rate debt securities, fixed income debt obligations, money market instruments, and other debt securities, including distressed securities that may be in default and have any or no credit rating. The fund can invest up to 15% of its assets in loans and securities that are not secured by any specific collateral. The fund can invest up to 15% in unsecured fixed rate high-yield bonds and 15% in second lien loans. The fund may invest in loans of foreign-domiciled borrowers and foreign debt securities, including emerging market debt securities, but expects that the majority of assets in which it invests will be invested in loans and securities of U.S. borrowers or issuers. The fund may invest in derivatives such as futures, forwards, and options for a variety of purposes, including as a means to manage fixed income exposure and to increase the fund's return as a non-hedging strategy that may be considered speculative. The fund can invest in leverage loan exchange traded funds ("ETF") to create exposure to the asset class. 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 – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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. Below investment grade, high-yield debt securities (commonly known as "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. 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. Distressed or Defaulted Securities – Investments in defaulted securities and obligations of distressed issuers, including securities that are, or may be, involved in reorganizations or other financial restructurings, either out of court or in bankruptcy, involve substantial risks and are considered speculative. The fund may suffer significant losses if the reorganization or restructuring is not completed as anticipated. The fund will generally not receive interest payments on the distressed securities and may incur costs to protect its investment. Repayment of defaulted securities and obligations of distressed issuers is subject to significant uncertainties. 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. Low trading volumes may result in a lack of liquidity and in extreme price volatility. Exchange Traded Funds – 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. 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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. 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. Interest rates in the U.S. have recently been historically low. 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. Junior Loans – Junior loans are subject to the same general risks inherent to any loan investment, including credit risk, market and liquidity risk and interest rate risk. Due to their lower place in the borrower's capital structure and possible unsecured status, junior loans involve a higher degree of overall risk than senior loans of the same borrower. 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. Loans – Loans are subject to the credit risk of nonpayment of principal or interest. Economic downturns or increases in interest rates may cause an increase in defaults, interest rate risk and liquidity risk. Loans may or may not be collateralized at the time of acquisition, and any collateral may be relatively illiquid or lose all or substantially all of its value subsequent to investment. In the event of bankruptcy of a borrower, the fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a loan. The fund's investments in loans are also subject to prepayment or call risk. 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time. 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. 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. 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 seeks to achieve its objective by primarily investing in the common stock of closed-end funds selected by Transamerica Asset Management, Inc. ("TAM"). The fund seeks to identify and exploit relative value opportunities in the closed-end fund universe. The overall investment philosophy is predicated on recognizing and capitalizing on market inefficiencies found in this universe. The combination of TAM's quantitative approach and research-driven process for selecting closed-end funds is intended to produce a portfolio focused on total return that is allocated across multiple sectors, strategies and managers. The fund's available investment universe is initially composed of those exchange-listed closed-end funds, which may include both foreign and domestic securities of all ratings and market capitalizations, with greater than $350 million in market capitalization and an average daily volume greater than $1 million. From this investment universe, TAM seeks to identify closed-end funds that are trading at a discount larger than the respective universe average, but are exhibiting signs of price appreciation. From the filtered universe of closed-end funds, TAM constructs the portfolio by utilizing a value investment approach that seeks to identify investment worthy ideas. TAM normally selects the combination of underlying closed-end funds in an effort to maximize the diversification of independent sources of risk. The allocation to a single underlying closed-end fund will generally not exceed 3%. The fund may also invest in exchange traded funds ("ETFs") in order to provide exposure to asset classes that are unavailable in the closed-end universe, and to provide additional sources of liquidity. Under normal market conditions, ETFs are not expected to comprise more than 20% of the fund's assets. The fund may have exposure to derivative instruments, such as options, futures, or forward contracts and swaps through its investment in the underlying closed-end funds and ETFs. The fund may also seek to earn a liquidity premium through its underlying closed-end fund investments by buying underlying closed-end funds when they are less liquid and selling them when they are more liquid. Each underlying closed-end fund and ETF has its own investment objective, principal investment strategies, and risk. It is not possible to predict the extent to which the fund will be invested in particular underlying closed-end funds at any time. The fund may be a significant shareholder in certain underlying closed-end funds, given the fund's planned investments in certain underlying closed-end funds, the fund considers multiple investments of up to 3% to be significant and, as such, the fund to be a "significant shareholder" of those underlying closed-end funds. TAM may change the fund's asset allocations and underlying closed-end funds at any time without notice to the shareholders and without shareholder approval. 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. The fund may also invest in cash when TAM is unable to identify attractive investment opportunities that meet the fund's investment criteria.

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 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 – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not 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. Below investment grade, high-yield debt securities (commonly known as “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 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, 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. 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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. 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. Interest rates in the U.S. have recently been historically low. 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 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 adviser 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time. New Fund – The fund is newly formed. Investors in the fund bear the risk that the Investment 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. Prepayment or Call – Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The fund also may lose any premium it paid on the security. Small and Medium Capitalization Companies – The fund will be exposed to additional risks as a result of its investments in the securities of small or medium capitalization companies. Small or medium capitalization companies may be more at risk than large capitalization companies because, among other things, they may have limited product lines, operating history, market or financial resources, or because they may depend on a limited management group. The prices of securities of small and medium capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions. Securities of small and medium capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses. Underlying Closed-end Funds and Exchange Traded Funds – Because the fund invests its assets in various underlying closed-end funds and ETFs (the “underlying funds”), its ability to achieve its investment objective depends largely on the performance of the underlying funds in which it invests. Each of the underlying funds in which the fund may invest has its own investment risks, and those risks can affect the value of the underlying funds' shares and therefore the value of the fund's investments. There can be no assurance that the investment objective of any underlying fund will be achieved. To the extent that the fund invests more of its assets in one underlying fund than in another, the fund will have greater exposure to the risks of that underlying fund. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying funds 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 or closed-end fund 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 a closed-end fund or an ETF can fluctuate up and down, and the fund could lose money investing in such a closed-end fund or an ETF if the prices of the securities owned by the closed-end fund or ETF go down. In addition, closed-end funds and ETFs are subject to the following risks that do not apply to conventional funds: (i) the market price of a closed-end fund’s or an ETF’s shares may be above or below the shares’ net asset value (shares of closed-end funds frequently trade at a discount from their net asset value); (ii) an active trading market for a closed-end fund’s or an ETF’s shares may not develop or be maintained; or (iii) trading of a closed-end fund’s or 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. Closed-end funds and ETFs may employ leverage, which also subjects the funds to increased risks such as increased volatility. 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.

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 Retail Class Transamerica Small Cap Core (USD $)	1 year	3 years
A	675	939
C	301	722
I	101	315

If the shares are not redeemed:

Expense Example, No Redemption Retail Class Transamerica Small Cap Core (USD $)	1 year	3 years
A	675	939
C	198	612
I	101	315

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.

Portfolio turnover rate is not included at this time because the fund did not commence operations until after the most recent fiscal year-end.

Principal Investment Strategies:

The fund normally invests primarily in stocks of companies with small market capitalizations which, in the opinion of the fund's sub-adviser, present an opportunity for significant increases in value, without consideration for current income. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of companies with small market capitalizations (or small-cap companies) and other investments with similar economic characteristics. The fund considers small-cap companies to be companies with market capitalizations that, at the time of initial purchase, are within the range of capitalization of the companies that are included in the Russell 2000^® Index¹ over time. As of June 30, 2013, the market capitalizations of companies in the Russell 2000^® Index ranged from $22.5 million to $5.9 billion. Over time, the capitalizations of the companies in the Russell 2000^® Index will change. As they do, the size of the companies in which the fund invests may change.

The fund may invest in ADRs and/or foreign securities trading on U.S. exchanges, which generally stay under 10% of portfolio assets. It will not trade securities on a non-U.S. exchange. Investment in derivatives, futures and swaps are not permitted.

The fund may also invest its assets in cash, cash equivalent securities or short-term debt securities, repurchase agreements and money market instruments. Generally, 5% or less of fund assets will be invested in cash and cash equivalents.

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.

• Cash Management and Defensive Investing – The value of investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, cash and cash equivalent securities 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 may not achieve its objective.

• 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.

• 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 Investments – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risk. Foreign countries 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.

• 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.

• 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 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 of issuers worldwide. Some governmental and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including in the U.S., Europe and beyond. 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, failure of efforts in response to the crisis, or investor perception that these efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. In addition, policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. The impact of these changes, and the practical implications for market participants, may not be fully known for some time.

• 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.

• 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.

• 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.

• 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.

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.
