Portfolio Turnover

Portfolio turnover, narrative

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover 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. The Fund is newly-created and, as a result, does not yet have a portfolio turnover rate.

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

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

Strategy, Heading

rr_StrategyHeading

Principal Investment Strategies

Strategy, Narrative

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund will invest at least 80% of its net assets (including amounts borrowed for investment purposes) in equity and debt securities of companies in emerging or frontier countries or markets. Emerging and frontier countries or markets are those countries or markets with low- to middle-income economies as classified by the World Bank or included in any of the Morgan Stanley Capital International (MSCI) emerging markets indices. The Fund's advisor considers a company to be in an emerging or frontier market country if the company has been organized under the laws of, has its principal offices in, or has its securities principally traded in, an emerging or frontier market country; or if the company derives at least 50% of its revenues; net profits; or incremental revenue growth (typically over the past five-years) from, or has at least 50% of assets or production capacities in, an emerging or frontier market country.

The Fund’s advisor expects the Fund to primarily invest in equity securities under normal circumstances. The Fund’s equity investments include common stock, preferred stock, depository receipts, rights and warrants. The Fund’s investments in depository receipts may include American, European, and Global Depository Receipts (“ADRs”, “EDRs”, and “GDRs”, respectively). Debt obligations in which the Fund invests will be investment grade and may include, but are not limited to, those of sovereign and corporate issuers of any maturity. Investment grade securities are those rated at the time of acquisition Baa3 or higher by Moody's Investors Service, Inc. ("Moody's"), or BBB- or higher by Standard & Poor's, a division of McGraw Hill Companies Inc. (“S&P”), or Fitch Ratings Ltd. (“Fitch”) or, if unrated by S&P, Moody's or Fitch, determined by the Fund’s advisor to be of comparable quality.

The Fund’s advisor uses a bottom-up approach that seeks to identify companies with attractive fundamentals, such as long-term historical growth in revenue and earnings, and/or a high probability for superior future growth. The advisor’s investment process seeks companies that are industry leaders with sustainable competitive advantages; corporate cultures emphasizing strong, quality and experienced management; low or no debt; and attractive relative valuations. The Fund’s advisor also considers other factors including political risk, monetary policy risk, and regulatory risk in selecting securities.

The Fund may invest in securities of any size companies. The Fund generally will invest in the securities of companies domiciled in at least three different countries. From time to time, the Fund may have a significant portion of its assets invested in the securities of companies domiciled in one or a few countries or regions.

The Fund is non-diversified and therefore is allowed to focus its investments in fewer companies than a fund that is required to diversify its portfolio.

Risk, Heading

rr_RiskHeading

Principal Risks of Investing

Risk, Narrative

rr_RiskNarrativeTextBlock

The Fund’s principal risks are mentioned below. Before you decide whether to invest in the Fund, carefully consider these risk factors and special considerations associated with investing in the Fund, which may cause investors to lose money.

Market Risk. Market risk is the risk that the Fund’s share price may be affected by a sudden decline in the market value of an investment, or by an overall decline in the stock market.

Equity Investments Risk. Investment in equity securities involves substantial risks and may be subject to wide and sudden fluctuations in market value, with a resulting fluctuation in the amount of profits and losses.

Foreign Investments Risk. The prices of foreign securities may be more volatile than those of U.S. securities because of economic and social conditions abroad, political developments, and changes in the regulatory environment of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the value of the Fund’s foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. The Fund’s investments in depository receipts are also subject to these risks.

Currency Risk. Foreign securities that trade in, and receive revenues in, foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Emerging Market Risk. The Fund’s investments in foreign issuers in developing or emerging market countries involve exposure to changes in economic and political factors. The economies of most emerging market countries are in the infancy stage of capital market development. As a result, their economic systems are still evolving and their political systems are typically less stable than those in developed economies. Emerging market countries often suffer from currency devaluation and higher rates of inflation.

Frontier Market Risk. Frontier market countries generally have smaller economies and even less developed capital markets than traditional emerging markets, and as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Small- and Mid-Cap Company Risk. The securities of small- or mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger companies or the market averages in general. In addition, such companies typically are subject to a greater degree of change in earnings and business prospects than are larger, more established companies.

Debt Securities Risk. Prices of debt securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect debt security prices and, accordingly, the Fund’s returns and share price (“interest rate risk”). In addition, debt securities may be subject to “call” or “extension” risk. Call risk is the risk that, during a period of falling interest rates, the issuer may redeem a security by repaying it early, which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates. Extension risk occurs during a rising interest rate environment because certain obligations will be paid off by an issuer more slowly than anticipated, causing the value of those securities held by the Fund to fall.

Credit Risk. An issuer of a debt security or counterparty could suffer an adverse change in financial condition that results in a payment default, security downgrade, or inability to meet a financial obligation.

Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Fund’s advisor applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

Non-Diversification Risk. The Fund is non-diversified, which means the Fund may focus its investments in the securities of a comparatively small number of issuers. Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

No Operating History. The Fund is a newly organized series of an open-end management investment company and has no operating history. As a result, prospective investors have no track record or history on which to base their investment decisions.

The Fund will invest primarily in equity securities of companies located throughout the world, including the United States. Under normal market conditions, the Fund will invest at least 40% of its net assets in companies organized, headquartered or doing a substantial amount of business outside the United States. The Fund’s advisor considers a company that has at least 50% of its assets, or derives at least 50% of its revenues from business, outside the United States as doing a substantial amount of business outside the United States.

The Fund’s equity investments include common stock, preferred stock, depository receipts, rights and warrants. The Fund’s investments in depository receipts may include American, European, and Global Depository Receipts (“ADRs”, “EDRs”, and “GDRs”, respectively).

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

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

Expense Example WCM Focused Emerging Markets Fund (USD $)	1 Year	3 Years
Investor Class	169	580
Institutional Class	144	503

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 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. The Fund is newly-created and, as a result, does not yet have a portfolio turnover rate.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets (including amounts borrowed for investment purposes) in equity and debt securities of companies in emerging or frontier countries or markets. Emerging and frontier countries or markets are those countries or markets with low- to middle-income economies as classified by the World Bank or included in any of the Morgan Stanley Capital International (MSCI) emerging markets indices. The Fund's advisor considers a company to be in an emerging or frontier market country if the company has been organized under the laws of, has its principal offices in, or has its securities principally traded in, an emerging or frontier market country; or if the company derives at least 50% of its revenues; net profits; or incremental revenue growth (typically over the past five-years) from, or has at least 50% of assets or production capacities in, an emerging or frontier market country.

The Fund’s advisor expects the Fund to primarily invest in equity securities under normal circumstances. The Fund’s equity investments include common stock, preferred stock, depository receipts, rights and warrants. The Fund’s investments in depository receipts may include American, European, and Global Depository Receipts (“ADRs”, “EDRs”, and “GDRs”, respectively). Debt obligations in which the Fund invests will be investment grade and may include, but are not limited to, those of sovereign and corporate issuers of any maturity. Investment grade securities are those rated at the time of acquisition Baa3 or higher by Moody's Investors Service, Inc. ("Moody's"), or BBB- or higher by Standard & Poor's, a division of McGraw Hill Companies Inc. (“S&P”), or Fitch Ratings Ltd. (“Fitch”) or, if unrated by S&P, Moody's or Fitch, determined by the Fund’s advisor to be of comparable quality.

The Fund’s advisor uses a bottom-up approach that seeks to identify companies with attractive fundamentals, such as long-term historical growth in revenue and earnings, and/or a high probability for superior future growth. The advisor’s investment process seeks companies that are industry leaders with sustainable competitive advantages; corporate cultures emphasizing strong, quality and experienced management; low or no debt; and attractive relative valuations. The Fund’s advisor also considers other factors including political risk, monetary policy risk, and regulatory risk in selecting securities.

The Fund may invest in securities of any size companies. The Fund generally will invest in the securities of companies domiciled in at least three different countries. From time to time, the Fund may have a significant portion of its assets invested in the securities of companies domiciled in one or a few countries or regions.

The Fund is non-diversified and therefore is allowed to focus its investments in fewer companies than a fund that is required to diversify its portfolio.

Principal Risks of Investing

The Fund’s principal risks are mentioned below. Before you decide whether to invest in the Fund, carefully consider these risk factors and special considerations associated with investing in the Fund, which may cause investors to lose money.

Market Risk. Market risk is the risk that the Fund’s share price may be affected by a sudden decline in the market value of an investment, or by an overall decline in the stock market.

Equity Investments Risk. Investment in equity securities involves substantial risks and may be subject to wide and sudden fluctuations in market value, with a resulting fluctuation in the amount of profits and losses.

Foreign Investments Risk. The prices of foreign securities may be more volatile than those of U.S. securities because of economic and social conditions abroad, political developments, and changes in the regulatory environment of foreign countries. In addition, changes in exchange rates and interest rates may adversely affect the value of the Fund’s foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. The Fund’s investments in depository receipts are also subject to these risks.

Currency Risk. Foreign securities that trade in, and receive revenues in, foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Emerging Market Risk. The Fund’s investments in foreign issuers in developing or emerging market countries involve exposure to changes in economic and political factors. The economies of most emerging market countries are in the infancy stage of capital market development. As a result, their economic systems are still evolving and their political systems are typically less stable than those in developed economies. Emerging market countries often suffer from currency devaluation and higher rates of inflation.

Frontier Market Risk. Frontier market countries generally have smaller economies and even less developed capital markets than traditional emerging markets, and as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Small- and Mid-Cap Company Risk. The securities of small- or mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger companies or the market averages in general. In addition, such companies typically are subject to a greater degree of change in earnings and business prospects than are larger, more established companies.

Debt Securities Risk. Prices of debt securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect debt security prices and, accordingly, the Fund’s returns and share price (“interest rate risk”). In addition, debt securities may be subject to “call” or “extension” risk. Call risk is the risk that, during a period of falling interest rates, the issuer may redeem a security by repaying it early, which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates. Extension risk occurs during a rising interest rate environment because certain obligations will be paid off by an issuer more slowly than anticipated, causing the value of those securities held by the Fund to fall.

Credit Risk. An issuer of a debt security or counterparty could suffer an adverse change in financial condition that results in a payment default, security downgrade, or inability to meet a financial obligation.

Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Fund’s advisor applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

Non-Diversification Risk. The Fund is non-diversified, which means the Fund may focus its investments in the securities of a comparatively small number of issuers. Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

No Operating History. The Fund is a newly organized series of an open-end management investment company and has no operating history. As a result, prospective investors have no track record or history on which to base their investment decisions.

Performance

The Fund is new and does not have a full calendar year performance record to compare against other mutual funds or broad measures of securities market performance such as indices. Performance information will be available after the Fund has been in operation for one calendar year.

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 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. The Fund is newly-created and, as a result, does not yet have a portfolio turnover rate.

Principal Investment Strategies

The Fund will invest primarily in equity securities of companies located throughout the world, including the United States. Under normal market conditions, the Fund will invest at least 40% of its net assets in companies organized, headquartered or doing a substantial amount of business outside the United States. The Fund’s advisor considers a company that has at least 50% of its assets, or derives at least 50% of its revenues from business, outside the United States as doing a substantial amount of business outside the United States.

The Fund’s equity investments include common stock, preferred stock, depository receipts, rights and warrants. The Fund’s investments in depository receipts may include American, European, and Global Depository Receipts (“ADRs”, “EDRs”, and “GDRs”, respectively).

The Fund’s advisor uses a bottom-up approach that seeks to identify companies with attractive fundamentals, such as long-term historical growth in revenue and earnings, and/or a high probability for superior future growth. The advisor’s investment process seeks companies that are industry leaders with sustainable competitive advantages; corporate cultures emphasizing strong, quality and experienced management; low or no debt; and attractive relative valuations. The Fund’s advisor also considers other factors including political risk, monetary policy risk, and regulatory risk in selecting securities.

Although the Fund may invest in securities of any size companies, it will generally invest in the securities of large, established multinational companies. The Fund generally will invest in securities of companies located in different regions and in at least three different countries. From time to time, the Fund may have a significant portion of its assets invested in the securities of companies in one or a few countries or regions.

The Fund is non-diversified and therefore is allowed to focus its investments in fewer companies than a fund that is required to diversify its portfolio.
