CRM International Opportunity Fund (Prospectus Summary) | CRM International Opportunity Fund

CRM INTERNATIONAL OPPORTUNITY FUND

INVESTMENT OBJECTIVE

CRM International Opportunity Fund seeks long-term capital appreciation.

FEES AND EXPENSES

This table sets forth the fees and expenses that you may pay if you buy and hold
shares of the Fund.

SHAREHOLDER FEES (fees paid directly from your investment)

Shareholder Fees CRM International Opportunity Fund	Investor Shares	Institutional Shares
Redemption Fee on Shares Held Less Than 30 Days (as a percentage of amount redeemed, if applicable)	1.50%	1.50%

ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses CRM International Opportunity Fund		Investor Shares	Institutional Shares
Management Fees		0.90%	0.90%
Distribution (12b-1) Fees		none	none
Shareholder Servicing Fee		0.25%	none
Other Miscellaneous Expenses		1.79%	1.94%
Total Other Expenses		2.04%	1.94%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1][2]	2.95%	2.85%
Fee Waiver and Expense Reimbursement	[2]	(1.44%)	(1.59%)
Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement	[1][2]	1.51%	1.26%

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 below shows what
you would pay if you invested $10,000 over the various time periods indicated.
The Example assumes that you reinvested all dividends and other distributions;
the average annual return was 5%; the Fund's total operating expenses
(reflecting applicable contractual fee waivers and expense reimbursement
arrangements) are charged and remain the same over the time periods; and you
redeemed all of your investment at the end of each time period.

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

Expense Example CRM International Opportunity Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Investor Shares	154	777	1,426	3,168
Institutional Shares	128	732	1,363	3,061

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.
During the most recent fiscal year, the Fund's portfolio turnover rate was 220%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in
equity and equity related securities of foreign companies. The Fund normally
invests in the securities of companies that are tied economically to at least
10 countries, other than the U.S. The Fund may invest in companies located in
developed and emerging markets. Emerging markets include countries that have
an emerging stock market as defined by Standard & Poor's, Inc., countries or
markets with low- to- middle-income economies as classified by the World Bank,
and other countries or markets with similar emerging characteristics. The Fund
may invest in companies of any size. For purposes of the 80% investment policy,
equity and equity related securities include: common and preferred stocks,
securities convertible into common stock, and warrants on common stock.

The Adviser evaluates investment opportunities for the Fund using a proprietary
value-oriented process that seeks to identify companies characterized by three
attributes: change, neglect and relative valuation. The Adviser seeks to identify
those changes that are material to a company's operations, outlook and prospects
while also identifying companies that it believes have been neglected by other
investors. The Adviser utilizes a primarily qualitative research process focused
on these attributes to identify and invest in relatively undervalued companies.
These factors formulate the Adviser's investment case for each company under
consideration for investment. An important function of the Adviser's investment
process is to set a price target at which the security will be sold, provided
that there has been no fundamental change in the investment case. The Adviser
monitors each security held by the Fund to determine if the security continues
to act in accordance with the Adviser's initial assessment. Ordinarily, once the
Adviser believes that an investment case has realized its anticipated prospects,
the security will be sold. Additionally, the security would typically be sold if
the identified change does not have the expected impact on earnings and cash flow
of the company or a company's fundamentals deteriorate, or due to other market
conditions that would cause the Adviser to believe a sale would be advisable.

PRINCIPAL INVESTMENT RISKS

It is possible to lose money by investing in the Fund. There is no guarantee
that the stock market or the stocks the Fund buys will increase in value. The
following is a summary description of certain risks of investing in the Fund.

Market Risk. Stock markets are volatile and can decline significantly in
response to adverse issuer, regulatory, market or economic developments.
Different parts of the U.S. market and different markets around the world can
react differently to these developments. When market prices fall, the value of
your investment will go down. 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. Further
defaults or restructurings by governments and others of their debt could have
additional adverse effects on economies, financial markets and asset valuations
around the world. Whether or not the Fund invests in securities of issuers
located in or with significant exposure to countries experiencing economic and
financial difficulties, these events could negatively affect the value and
liquidity of the Fund's investments. The Fund may experience a substantial or
complete loss on any individual security. In addition, legislation recently
enacted in the U.S. calls for changes in many aspects of financial regulation.
The impact of the legislation on the markets, and the practical implications for
market participants, may not be fully known for some time.

Company Risk. The value of an individual security or particular type of security
can be more volatile than the market as a whole and can perform differently from
the market as a whole. This may result from a wide variety of factors that affect
particular companies or industries, including changes in market demand for
particular goods and services, increases in costs of supply, changes in management,
increased competition and changes in regulatory environment.

Value Investing Risk. Value stocks can perform differently from the market as a
whole and other types of stocks and can continue to be undervalued by the market
for long periods of time. The Adviser may be incorrect when it decides that a
stock is undervalued by the market.

Portfolio Selection Risk. The value of your investment may decrease if the
Adviser's judgment about the attractiveness, value of, or market trends affecting
a particular security, industry or sector, country or region, or about market
movements, is incorrect.

Risks of Foreign Investments. Investing in foreign securities involves special
risks that can increase the potential for losses. These risks may include
nationalization or expropriation of assets, illiquid foreign securities markets,
confiscatory taxation, foreign withholding taxes, natural disasters and
political, economic or social instability. Because many foreign markets are
smaller, less liquid and more volatile, the Fund may not be able to sell
portfolio securities at times, in amounts and at prices it considers reasonable.
In some foreign countries, less information is available about issuers and
markets. Foreign markets may offer less protection to investors. Foreign stocks
can fluctuate more widely in price than comparable U.S. stocks, and they may
also be less liquid.

Currency Risk. The Fund generally invests in securities denominated in foreign
currencies, and could experience gains or losses solely on changes in the
exchange rate between foreign currencies and the U.S. dollar. Currency exchange
rates can be volatile, and are affected by factors such as general economic
conditions, the actions of the U.S. and foreign governments or central banks,
and the imposition of currency controls or restrictions and speculation.

Emerging Markets Risk.The risks of investing in foreign securities are generally
greater in emerging markets, or to the extent that the Fund invests significantly
in one region or country. The extent of economic development, political stability,
market depth, infrastructure, capitalization and regulatory oversight can be less
than in more developed markets. The economies of emerging market countries may be
dependent on relatively few industries that are more susceptible to local and
global changes. Emerging market countries may experience rising interest rates,
or, more significantly, rapid inflation or hyperinflation.

Risks of Small and Mid Cap Companies. Compared to mutual funds that focus
exclusively on large capitalization companies, the Fund may be more volatile
because it also invests in small and/or mid capitalization companies. Small and
mid capitalization companies are more likely to have more limited product lines,
fewer capital resources and less depth of management than larger companies.
Securities of smaller companies may have limited liquidity and may be difficult
to value or to sell at an advantageous time or without a substantial drop in
price.

Focus Risk. To the extent that the Fund invests in a smaller number of issuers
or emphasizes investments in particular industries or market sectors, the Fund
will be subject to a greater degree to any market price movements, regulatory or
technological changes, economic conditions or other developments affecting those
issuers or companies in those industries or market sectors.

Portfolio Turnover Risk.If the Fund does a lot of trading, it may incur additional
operating expenses, which would reduce performance, and could cause shareowners to
incur a higher level of taxable income or capital gains.

Expense Risk. Your actual costs of investing in the Fund may be higher than the
expenses shown in "Annual Fund Operating Expenses" 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.

These and other risks are discussed in more detail later in this prospectus or
in the statement of additional information.

An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The bar chart and the average annual total return table below illustrate the risks
and volatility of an investment in the Fund. The bar chart shows changes in the
Fund's performance from calendar year to calendar year for Institutional Shares.
The table shows how the Fund's average annual total returns for one year and since
inception, both before and after taxes, compare with those of the MSCI EAFE Index,
a broad-based measure of market performance. Total returns would have been lower
had certain fees and expenses not been waived. The Fund makes updated performance
information available at the Fund's website, www.crmfunds.com/performance_daily.aspx,
or at the following telephone number: 800-CRM-2883. Of course, the Fund's past
performance, both before and after taxes, does not necessarily indicate how the
Fund will perform in the future.

After-tax returns are calculated using the historical highest individual federal
marginal income tax rates and do not reflect the impact of state and local taxes.
Actual after-tax returns will depend on your tax situation, may differ from those
shown and are not relevant if you hold your shares through tax-deferred arrangements,
such as 401(k) plans or individual retirement accounts. After-tax returns are shown
only for Institutional Shares. After-tax returns for Investor Shares will vary.

[1] Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets that is included in the Fund's financial highlights, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

[2] The Adviser has a contractual obligation to waive a portion of its fees and to assume certain expenses of the Fund to the extent that the total annual fund operating expenses, excluding taxes, extraordinary expenses, brokerage commissions, interest and acquired fund fees and expenses, exceed 1.50% and 1.25% of average daily net assets of Investor Shares and Institutional Shares, respectively. These expense limitations are in effect until November 1, 2013. Prior to that date, the arrangement may be terminated for a class only by the vote of the Board of Trustees of the Fund.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, under normal circumstances, invests at least 80% of its assets in equity and equity related securities of U.S. and non-U.S. companies with market capitalizations at the time of initial purchase within the range of those in the Russell 1000 Value Index ("large cap companies") that are publicly traded on a U.S. securities market. The market capitalization range of the Index changes constantly, and as a result, the capitalization of large cap companies in which the Fund will invest will also change. As of September 30, 2012, the market capitalization range of the Index was approximately $300 million to $427.6 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, securities convertible into common stock, and warrants on common stock.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, under normal circumstances, invests at least 80% of its assets in equity and equity related securities of U.S. and non-U.S. companies that are publicly traded on a U.S. securities market. There are no limits on the market capitalizations of the companies in which the Fund may invest. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, securities convertible into common stock, and warrants on common stock. The Adviser evaluates investment opportunities for the Fund using a proprietary value-oriented process that seeks to identify companies characterized by three attributes: change, neglect and relative valuation. The Adviser seeks to identify those changes that are material to a company's operations, outlook and prospects while also identifying companies that it believes have been neglected by other investors. The Adviser utilizes a primarily qualitative research process focused on these attributes to identify and invest in relatively undervalued companies. These factors formulate the Adviser's investment case for each company under consideration for investment. An important function of the Adviser's investment process is to set a price target at which the security will be sold, provided that there has been no fundamental change in the investment case. The Adviser monitors each security held by the Fund to determine if the security continues to act in accordance with the Adviser's initial assessment. Ordinarily, once the Adviser believes that an investment case has realized its anticipated prospects, the security will be sold. Additionally, the security would typically be sold if the identified change does not have the expected impact on earnings and cash flow of the company or a company's fundamentals deteriorate, or due to other market conditions that would cause the Adviser to believe a sale would be advisable.
Risk [Heading]	rr_RiskHeading	PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	It is possible to lose money by investing in the Fund. There is no guarantee that the stock market or the stocks the Fund buys will increase in value. The following is a summary description of certain risks of investing in the Fund. Market Risk. Stock markets are volatile and can decline significantly in response to adverse issuer, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. When market prices fall, the value of your investment will go down. 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. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. Whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, these events could negatively affect the value and liquidity of the Fund's investments. The Fund may experience a substantial or complete loss on any individual security. In addition, legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time. Company Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole. This may result from a wide variety of factors that affect particular companies or industries, including changes in market demand for particular goods and services, increases in costs of supply, changes in management, increased competition and changes in regulatory environment. Value Investing Risk. Value stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time. The Adviser may be incorrect when it decides that a stock is undervalued by the market. Portfolio Selection Risk. The value of your investment may decrease if the Adviser's judgment about the attractiveness, value of, or market trends affecting a particular security, industry or sector, country or region, or about market movements, is incorrect. Risks of Small and Mid Cap Companies. Compared to mutual funds that focus exclusively on large capitalization companies, the Fund may be more volatile because it also invests in small and/or mid capitalization companies. Small and mid capitalization companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Securities of smaller companies may have limited liquidity and may be difficult to value or to sell at an advantageous time or without a substantial drop in price. Risks of Foreign Investments. Investing in foreign securities involves special risks that can increase the potential for losses. These risks may include nationalization or expropriation of assets, illiquid foreign securities markets, confiscatory taxation, foreign withholding taxes, imposition of currency controls or restrictions, natural disasters and political, economic or social instability. Because many foreign markets are smaller, less liquid and more volatile, the Fund may not be able to sell portfolio securities at times, in amounts and at prices it considers reasonable. In some foreign countries, less information is available about issuers and markets. Foreign markets may offer less protection to investors. Foreign stocks can fluctuate more widely in price than comparable U.S. stocks, and they may also be less liquid. Currency fluctuations could erase investment gains or add to investment losses. Focus Risk. To the extent that the Fund invests in a smaller number of issuers or emphasizes investments in particular industries or market sectors, the Fund will be subject to a greater degree to any market price movements, regulatory or technological changes, economic conditions or other developments affecting those issuers or companies in those industries or market sectors. Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. Expense Risk. Your actual costs of investing in the Fund may be higher than the expenses shown in "Annual Fund Operating Expenses" 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. These and other risks are discussed in more detail later in this prospectus or in the statement of additional information. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

SMALL/MID CAP VALUE FUND

INVESTMENT OBJECTIVE

CRM Small/Mid Cap Value Fund seeks long-term capital appreciation.

FEES AND EXPENSES

This table sets forth 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 CRM SMALL/MID CAP VALUE FUND		Investor Shares	Institutional Shares
Management Fees		0.75%	0.75%
Distribution (12b-1) Fees		none	none
Shareholder Servicing Fee		0.25%	none
Other Miscellaneous Expenses		0.08%	0.12%
Total Other Expenses		0.33%	0.12%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1]	1.09%	0.88%

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 below shows what
you would pay if you invested $10,000 over the various time periods indicated.
The Example assumes that you reinvested all dividends and other distributions;
the average annual return was 5%; the Fund's total operating expenses are
charged and remain the same over the time periods; and you redeemed all of your
investment at the end of each time period.

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

Expense Example CRM SMALL/MID CAP VALUE FUND (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Investor Shares	111	347	601	1,329
Institutional Shares	90	281	488	1,084

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.
During the most recent fiscal year, the Fund's portfolio turnover rate was 96%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in
equity and equity related securities of U.S. and non-U.S. companies with market
capitalizations at the time of initial purchase within the range of those in
the Russell 2500 Value Index or in the S&P Mid Cap 400 Value Index (together,
"small/mid cap companies") that are publicly traded on a U.S. securities market.
The market capitalization ranges of the Indices change constantly, and as a
result, the capitalization of small/mid cap companies in which the Fund will
invest will also change. As of September 30, 2012, the market capitalization
range of the Russell 2500 Value Index was approximately $45 million to $8.5
billion, and the market capitalization range of the S&P Mid Cap 400 Value
Index was approximately $237 million to $14.7 billion. For purposes of the 80%
investment policy, equity and equity related securities include: common and
preferred stocks, securities convertible into common stock, and warrants on
common stock.

The Adviser evaluates investment opportunities for the Fund using a proprietary
value-oriented process that seeks to identify companies characterized by three
attributes: change, neglect and relative valuation. The Adviser seeks to identify
those changes that are material to a company's operations, outlook and prospects
while also identifying companies that it believes have been neglected by other
investors. The Adviser utilizes a primarily qualitative research process focused
on these attributes to identify and invest in relatively undervalued companies.
These factors formulate the Adviser's investment case for each company under
consideration for investment. An important function of the Adviser's investment
process is to set a price target at which the security will be sold, provided
that there has been no fundamental change in the investment case. The Adviser
monitors each security held by the Fund to determine if the security continues
to act in accordance with the Adviser's initial assessment. Ordinarily, once
the Adviser believes that an investment case has realized its anticipated
prospects, the security will be sold. Additionally, the security would typically
be sold if the identified change does not have the expected impact on earnings
and cash flow of the company or a company's fundamentals deteriorate, or due to
other market conditions that would cause the Adviser to believe a sale would be
advisable.

PRINCIPAL INVESTMENT RISKS

It is possible to lose money by investing in the Fund. There is no guarantee
that the stock market or the stocks the Fund buys will increase in value. The
following is a summary description of certain risks of investing in the Fund.

Market Risk. Stock markets are volatile and can decline significantly in
response to adverse issuer, regulatory, market or economic developments.
Different parts of the U.S. market and different markets around the world can
react differently to these developments. When market prices fall, the value of
your investment will go down. 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. Further
defaults or restructurings by governments and others of their debt could have
additional adverse effects on economies, financial markets and asset valuations
around the world. Whether or not the Fund invests in securities of issuers
located in or with significant exposure to countries experiencing economic and
financial difficulties, these events could negatively affect the value and
liquidity of the Fund's investments. The Fund may experience a substantial or
complete loss on any individual security. In addition, legislation recently
enacted in the U.S. calls for changes in many aspects of financial regulation.
The impact of the legislation on the markets, and the practical implications for
market participants, may not be fully known for some time.

Company Risk. The value of an individual security or particular type of security
can be more volatile than the market as a whole and can perform differently from
the market as a whole. This may result from a wide variety of factors that affect
particular companies or industries, including changes in market demand for
particular goods and services, increases in costs of supply, changes in
management, increased competition and changes in regulatory environment.

Value Investing Risk. Value stocks can perform differently from the market as a
whole and other types of stocks and can continue to be undervalued by the market
for long periods of time. The Adviser may be incorrect when it decides that a
stock is undervalued by the market.

Portfolio Selection Risk. The value of your investment may decrease if the
Adviser's judgment about the attractiveness, value of, or market trends affecting
a particular security, industry or sector, country or region, or about market
movements, is incorrect.

Risks of Small and Mid Cap Companies. Compared to mutual funds that focus
exclusively on large capitalization companies, the Fund may be more volatile
because it invests in small and/or mid capitalization companies. Small and mid
capitalization companies are more likely to have more limited product lines,
fewer capital resources and less depth of management than larger companies.
Securities of smaller companies may have limited liquidity and may be difficult
to value or to sell at an advantageous time or without a substantial drop in
price.

Risks of Foreign Investments. Investing in foreign securities involves special
risks that can increase the potential for losses. These risks may include
nationalization or expropriation of assets, illiquid foreign securities markets,
confiscatory taxation, foreign withholding taxes, imposition of currency
controls or restrictions, natural disasters and political, economic or social
instability. Because many foreign markets are smaller, less liquid and more
volatile, the Fund may not be able to sell portfolio securities at times, in
amounts and at prices it considers reasonable. In some foreign countries, less
information is available about issuers and markets. Foreign markets may offer
less protection to investors. Foreign stocks can fluctuate more widely in price
than comparable U.S. stocks, and they may also be less liquid. Currency
fluctuations could erase investment gains or add to investment losses.

Focus Risk. To the extent that the Fund invests in a smaller number of issuers
or emphasizes investments in particular industries or market sectors, the Fund
will be subject to a greater degree to any market price movements, regulatory or
technological changes, economic conditions or other developments affecting those
issuers or companies in those industries or market sectors.

Portfolio Turnover Risk.If the Fund does a lot of trading, it may incur additional
operating expenses, which would reduce performance, and could cause shareowners to
incur a higher level of taxable income or capital gains.

Expense Risk. Your actual costs of investing in the Fund may be higher than the
expenses shown in "Annual Fund Operating Expenses" 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.

These and other risks are discussed in more detail later in this prospectus or
in the statement of additional information.

An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The bar chart and the average annual total return table below illustrate the risks
and volatility of an investment in the Fund. The bar chart shows changes in the
Fund's performance from calendar year to calendar year for Institutional Shares.
The table shows how the Fund's average annual total returns for one year, five
years and since inception, both before and after taxes, compare with those of the
Russell 2500 Value Index and the Russell 2500 Index, two broad based measures of
market performance. This performance information includes performance of the Fund's
predecessor, the CRM Small/Mid Cap Value Fund (a series of WT Mutual Fund) for
periods from September 1, 2004 (commencement of operations) through September 30,
2005. Total returns would have been lower had certain fees and expenses not been
waived. The Fund makes updated performance information available at the Fund's
website, www.crmfunds.com/performance_daily.aspx, or at the following telephone
number: 800-CRM-2883. Of course, the Fund's past performance, both before and
after taxes, does not necessarily indicate how the Fund will perform in the future.

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 below shows what
you would pay if you invested $10,000 over the various time periods indicated.
The Example assumes that you reinvested all dividends and other distributions;
the average annual return was 5%; the Fund's total operating expenses
(reflecting applicable contractual fee waivers and expense reimbursement
arrangements) are charged and remain the same over the time periods; and you
redeemed all of your investment at the end of each time period.

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

Expense Example CRM Global Opportunity Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Investor Shares	154	502	875	1,923
Institutional Shares	128	427	748	1,657

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.
During the most recent fiscal year, the Fund's portfolio turnover rate was 191%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in
equity and equity related securities of U.S. and foreign companies. The Fund
normally invests in the securities of companies that are tied economically to at
least 10 countries, including the U.S. The Fund may invest in companies located
in developed and emerging markets. Emerging markets include countries that have
an emerging stock market as defined by Standard & Poor's, Inc., countries or
markets with low- to middle-income economies as classified by the World Bank,
and other countries or markets with similar emerging characteristics. The Fund
may at any one time invest all or substantially all of its assets in foreign
companies and at another time invest substantially in U.S. companies, although,
under normal market conditions, it is expected that a majority of the Fund's
assets will be invested in foreign companies. The Fund may invest in companies
of any size. For purposes of the 80% investment policy, equity and equity
related securities include: common and preferred stocks, securities convertible
into common stock, and warrants on common stock.

The Adviser evaluates investment opportunities for the Fund using a proprietary
value-oriented process that seeks to identify companies characterized by three
attributes: change, neglect and relative valuation. The Adviser seeks to identify
those changes that are material to a company's operations, outlook and prospects
while also identifying companies that it believes have been neglected by other
investors. The Adviser utilizes a primarily qualitative research process focused
on these attributes to identify and invest in relatively undervalued companies.
These factors formulate the Adviser's investment case for each company under
consideration for investment. An important function of the Adviser's investment
process is to set a price target at which the security will be sold, provided
that there has been no fundamental change in the investment case. The Adviser
monitors each security held by the Fund to determine if the security continues
to act in accordance with the Adviser's initial assessment. Ordinarily, once the
Adviser believes that an investment case has realized its anticipated prospects,
the security will be sold. Additionally, the security would typically be sold if
the identified change does not have the expected impact on earnings and cash
flow of the company or a company's fundamentals deteriorate, or due to other
market conditions that would cause the Adviser to believe a sale would be advisable.

PRINCIPAL INVESTMENT RISKS

It is possible to lose money by investing in the Fund. There is no guarantee
that the stock market or the stocks the Fund buys will increase in value. The
following is a summary description of certain risks of investing in the Fund.

Market Risk. Stock markets are volatile and can decline significantly in
response to adverse issuer, regulatory, market or economic developments.
Different parts of the U.S. market and different markets around the world can
react differently to these developments. When market prices fall, the value of
your investment will go down. 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. Further
defaults or restructurings by governments and others of their debt could have
additional adverse effects on economies, financial markets and asset valuations
around the world. Whether or not the Fund invests in securities of issuers
located in or with significant exposure to countries experiencing economic and
financial difficulties, these events could negatively affect the value and
liquidity of the Fund's investments. The Fund may experience a substantial or
complete loss on any individual security. In addition, legislation recently
enacted in the U.S. calls for changes in many aspects of financial regulation.
The impact of the legislation on the markets, and the practical implications for
market participants, may not be fully known for some time.

Company Risk. The value of an individual security or particular type of security
can be more volatile than the market as a whole and can perform differently from
the market as a whole. This may result from a wide variety of factors that affect
particular companies or industries, including changes in market demand for
particular goods and services, increases in costs of supply, changes in management,
increased competition and changes in regulatory environment.

Value Investing Risk. Value stocks can perform differently from the market as a
whole and other types of stocks and can continue to be undervalued by the market
for long periods of time. The Adviser may be incorrect when it decides that a
stock is undervalued by the market.

Portfolio Selection Risk. The value of your investment may decrease if the Adviser's
judgment about the attractiveness, value of, or market trends affecting a particular
security, industry or sector, country or region, or about market movements, is
incorrect.

Risks of Foreign Investments. Investing in foreign securities involves special
risks that can increase the potential for losses. These risks may include
nationalization or expropriation of assets, illiquid foreign securities markets,
confiscatory taxation, foreign withholding taxes, natural disasters and
political, economic or social instability. Because many foreign markets are
smaller, less liquid and more volatile, the Fund may not be able to sell
portfolio securities at times, in amounts and at prices it considers reasonable.
In some foreign countries, less information is available about issuers and
markets. Foreign markets may offer less protection to investors. Foreign stocks
can fluctuate more widely in price than comparable U.S. stocks, and they may
also be less liquid.

Currency Risk. The Fund generally invests in securities denominated in foreign
currencies, and could experience gains or losses solely on changes in the
exchange rate between foreign currencies and the U.S. dollar. Currency exchange
rates can be volatile, and are affected by factors such as general economic
conditions, the actions of the U.S. and foreign governments or central banks,
and the imposition of currency controls or restrictions and speculation.

Emerging Markets Risk.The risks of investing in foreign securities are generally
greater in emerging markets, or to the extent that the Fund invests significantly
in one region or country. The extent of economic development, political stability,
market depth, infrastructure, capitalization and regulatory oversight can be less
than in more developed markets. The economies of emerging market countries may be
dependent on relatively few industries that are more susceptible to local and
global changes. Emerging market countries may experience rising interest rates,
or, more significantly, rapid inflation or hyperinflation.

Risks of Small and Mid Cap Companies. Compared to mutual funds that focus
exclusively on large capitalization companies, the Fund may be more volatile
because it also invests in small and/or mid capitalization companies. Small and
mid capitalization companies are more likely to have more limited product lines,
fewer capital resources and less depth of management than larger companies.
Securities of smaller companies may have limited liquidity and may be difficult
to value or sell at advantageous time or without a substantial drop in price.

Focus Risk. To the extent that the Fund invests in a smaller number of issuers
or emphasizes investments in particular industries or market sectors, the Fund
will be subject to a greater degree to any market price movements, regulatory or
technological changes, economic conditions or other developments affecting those
issuers or companies in those industries or market sectors.

Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur
additional operating expenses, which would reduce performance, and could cause
shareowners to incur a higher level of taxable income or capital gains.

Expense Risk. Your actual costs of investing in the Fund may be higher than the
expenses shown in "Annual Fund Operating Expenses" 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.

These and other risks are discussed in more detail later in this prospectus or
in the statement of additional information.

An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

These expense limitations are in effect until November 1, 2013. Prior to that date, the arrangement may be terminated for a class only by the vote of the Board of Trustees of the Fund.

CRM SMALL CAP VALUE FUND

INVESTMENT OBJECTIVE

CRM Small Cap Value Fund seeks long-term capital appreciation.

FEES AND EXPENSES

This table sets forth 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 CRM SMALL CAP VALUE FUND		Investor Shares	Institutional Shares
Management Fees		0.75%	0.75%
Distribution (12b-1) Fees		none	none

Total Other Expenses		0.33%	0.10%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1]	1.09%	0.86%

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 below shows what
you would pay if you invested $10,000 over the various time periods indicated.
The Example assumes that you reinvested all dividends and other distributions;
the average annual return was 5%; the Fund's total operating expenses are
charged and remain the same over the time periods; and you redeemed all of your
investment at the end of each time period.

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

Expense Example CRM SMALL CAP VALUE FUND (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Investor Shares	111	347	601	1,329
Institutional Shares	88	274	477	1,061

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.
During the most recent fiscal year, the Fund's portfolio turnover rate was 103%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in
equity and equity related securities of U.S. and non-U.S. companies with market
capitalizations at the time of initial purchase within the range of those in the
Russell 2000 Value Index ("small cap companies") that are publicly traded on a
U.S. securities market. The market capitalization range of the Index changes
constantly, and as a result, the capitalization of small cap companies in which
the Fund will invest will also change. As of September 30, 2012, the market
capitalization range of the Index was approximately $45 million to $3.8 billion.
For purposes of the 80% investment policy, equity and equity related securities
include: common and preferred stocks, securities convertible into common stock,
and warrants on common stock.

The Adviser evaluates investment opportunities for the Fund using a proprietary
value-oriented process that seeks to identify companies characterized by three
attributes: change, neglect and relative valuation. The Adviser seeks to
identify those changes that are material to a company's operations, outlook and
prospects while also identifying companies that it believes have been neglected

investment process is to set a price target at which the security will be sold,
provided that there has been no fundamental change in the investment case. The
Adviser monitors each security held by the Fund to determine if the security
continues to act in accordance with the Adviser's initial assessment. Ordinarily,
once the Adviser believes that an investment case has realized its anticipated
prospects, the security will be sold. Additionally, the security would typically
be sold if the identified change does not have the expected impact on earnings
and cash flow of the company, the company's fundamentals deteriorate, or due to
other market conditions that would cause the Adviser to believe a sale would be
advisable.

PRINCIPAL INVESTMENT RISKS

It is possible to lose money by investing in the Fund. There is no guarantee
that the stock market or the stocks the Fund holds will increase in value. The
following is a summary description of certain risks of investing in the Fund.

Risks of Small Cap Companies. Compared to mutual funds that focus exclusively on
large capitalization companies, the Fund may be more volatile because it invests
in small capitalization companies. Small capitalization companies are more likely
to have more limited product lines, fewer capital resources and less depth of
management than larger companies. Securities of smaller companies may have
limited liquidity and may be difficult to value or to sell at an advantageous

Risks of Foreign Investments. Investing in foreign securities involves special
risks that can increase the potential for losses. These risks may include
nationalization or expropriation of assets, illiquid foreign securities markets,
confiscatory taxation, foreign withholding taxes, imposition of currency
controls or restrictions, natural disasters and political, economic or social
instability. Because many foreign markets are smaller, less liquid and more
volatile, the Fund may not be able to sell portfolio securities at times, in
amounts and at prices it considers reasonable. In some foreign countries, less
information is available about issuers and markets. Foreign markets may offer
less protection to investors. Foreign stocks can fluctuate more widely in price
than comparable U.S. stocks, and they may also be less liquid. Currency
fluctuations could erase investment gains or add to investment losses.

Focus Risk. To the extent that the Fund invests in a smaller number of issuers
or emphasizes investments in particular industries or market sectors, the Fund
will be subject to a greater degree to any market price movements, regulatory or
technological change, economic conditions or other developments affecting those
issuers or companies in those industries or market sectors.

Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur
additional operating expenses, which would reduce performance, and could cause
shareowners to incur a higher level of taxable income or capital gains.

Expense Risk. Your actual costs of investing in the Fund may be higher than the
expenses shown in "Annual Fund Operating Expenses" 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.

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. During the most recent fiscal year, the Fund's portfolio turnover rate was 220% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, under normal circumstances, invests at least 80% of its assets in equity and equity related securities of foreign companies. The Fund normally invests in the securities of companies that are tied economically to at least 10 countries, other than the U.S. The Fund may invest in companies located in developed and emerging markets. Emerging markets include countries that have an emerging stock market as defined by Standard & Poor's, Inc., countries or markets with low- to- middle-income economies as classified by the World Bank, and other countries or markets with similar emerging characteristics. The Fund may invest in companies of any size. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, securities convertible into common stock, and warrants on common stock. The Adviser evaluates investment opportunities for the Fund using a proprietary value-oriented process that seeks to identify companies characterized by three attributes: change, neglect and relative valuation. The Adviser seeks to identify those changes that are material to a company's operations, outlook and prospects while also identifying companies that it believes have been neglected by other investors. The Adviser utilizes a primarily qualitative research process focused on these attributes to identify and invest in relatively undervalued companies. These factors formulate the Adviser's investment case for each company under consideration for investment. An important function of the Adviser's investment process is to set a price target at which the security will be sold, provided that there has been no fundamental change in the investment case. The Adviser monitors each security held by the Fund to determine if the security continues to act in accordance with the Adviser's initial assessment. Ordinarily, once the Adviser believes that an investment case has realized its anticipated prospects, the security will be sold. Additionally, the security would typically be sold if the identified change does not have the expected impact on earnings and cash flow of the company or a company's fundamentals deteriorate, or due to other market conditions that would cause the Adviser to believe a sale would be advisable.
Risk [Heading]	rr_RiskHeading	PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	It is possible to lose money by investing in the Fund. There is no guarantee that the stock market or the stocks the Fund buys will increase in value. The following is a summary description of certain risks of investing in the Fund. Market Risk. Stock markets are volatile and can decline significantly in response to adverse issuer, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. When market prices fall, the value of your investment will go down. 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. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. Whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, these events could negatively affect the value and liquidity of the Fund's investments. The Fund may experience a substantial or complete loss on any individual security. In addition, legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time. Company Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole. This may result from a wide variety of factors that affect particular companies or industries, including changes in market demand for particular goods and services, increases in costs of supply, changes in management, increased competition and changes in regulatory environment. Value Investing Risk. Value stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time. The Adviser may be incorrect when it decides that a stock is undervalued by the market. Portfolio Selection Risk. The value of your investment may decrease if the Adviser's judgment about the attractiveness, value of, or market trends affecting a particular security, industry or sector, country or region, or about market movements, is incorrect. Risks of Foreign Investments. Investing in foreign securities involves special risks that can increase the potential for losses. These risks may include nationalization or expropriation of assets, illiquid foreign securities markets, confiscatory taxation, foreign withholding taxes, natural disasters and political, economic or social instability. Because many foreign markets are smaller, less liquid and more volatile, the Fund may not be able to sell portfolio securities at times, in amounts and at prices it considers reasonable. In some foreign countries, less information is available about issuers and markets. Foreign markets may offer less protection to investors. Foreign stocks can fluctuate more widely in price than comparable U.S. stocks, and they may also be less liquid. Currency Risk. The Fund generally invests in securities denominated in foreign currencies, and could experience gains or losses solely on changes in the exchange rate between foreign currencies and the U.S. dollar. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, and the imposition of currency controls or restrictions and speculation. Emerging Markets Risk.The risks of investing in foreign securities are generally greater in emerging markets, or to the extent that the Fund invests significantly in one region or country. The extent of economic development, political stability, market depth, infrastructure, capitalization and regulatory oversight can be less than in more developed markets. The economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may experience rising interest rates, or, more significantly, rapid inflation or hyperinflation. Risks of Small and Mid Cap Companies. Compared to mutual funds that focus exclusively on large capitalization companies, the Fund may be more volatile because it also invests in small and/or mid capitalization companies. Small and mid capitalization companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Securities of smaller companies may have limited liquidity and may be difficult to value or to sell at an advantageous time or without a substantial drop in price. Focus Risk. To the extent that the Fund invests in a smaller number of issuers or emphasizes investments in particular industries or market sectors, the Fund will be subject to a greater degree to any market price movements, regulatory or technological changes, economic conditions or other developments affecting those issuers or companies in those industries or market sectors. Portfolio Turnover Risk.If the Fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. Expense Risk. Your actual costs of investing in the Fund may be higher than the expenses shown in "Annual Fund Operating Expenses" 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. These and other risks are discussed in more detail later in this prospectus or in the statement of additional information. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, under normal circumstances, invests at least 80% of its assets in equity and equity related securities of U.S. and non-U.S. companies with market capitalizations at the time of initial purchase within the range of those in the Russell 2000 Value Index ("small cap companies") that are publicly traded on a U.S. securities market. The market capitalization range of the Index changes constantly, and as a result, the capitalization of small cap companies in which the Fund will invest will also change. As of September 30, 2012, the market capitalization range of the Index was approximately $45 million to $3.8 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, securities convertible into common stock, and warrants on common stock. The Adviser evaluates investment opportunities for the Fund using a proprietary value-oriented process that seeks to identify companies characterized by three attributes: change, neglect and relative valuation.

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	It is possible to lose money by investing in the Fund. There is no guarantee that the stock market or the stocks the Fund holds will increase in value. The following is a summary description of certain risks of investing in the Fund. Market Risk. Stock markets are volatile and can decline significantly in response to adverse issuer, regulatory, market or economic developments.

The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time. Company Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole. This may result from a wide variety of factors that affect particular companies or industries, including changes in market demand for particular goods and services, increases in costs of supply, changes in management, increased competition and changes in regulatory environment. Value Investing Risk. Value stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time. The Adviser may be incorrect when it decides that a stock is undervalued by the market. Portfolio Selection Risk. The value of your investment may decrease if the Adviser's judgment about the attractiveness, value of, or market trends affecting a particular security, industry or sector, country or region, or about market movements, is incorrect. Risks of Small Cap Companies. Compared to mutual funds that focus exclusively on large capitalization companies, the Fund may be more volatile because it invests in small capitalization companies. Small capitalization companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Securities of smaller companies may have limited liquidity and may be difficult to value or to sell at an advantageous time or without a substantial drop in price. Risks of Foreign Investments. Investing in foreign securities involves special risks that can increase the potential for losses. These risks may include nationalization or expropriation of assets, illiquid foreign securities markets, confiscatory taxation, foreign withholding taxes, imposition of currency controls or restrictions, natural disasters and political, economic or social instability. Because many foreign markets are smaller, less liquid and more volatile, the Fund may not be able to sell portfolio securities at times, in amounts and at prices it considers reasonable. In some foreign countries, less information is available about issuers and markets. Foreign markets may offer less protection to investors. Foreign stocks can fluctuate more widely in price than comparable U.S. stocks, and they may also be less liquid. Currency fluctuations could erase investment gains or add to investment losses. Focus Risk. To the extent that the Fund invests in a smaller number of issuers or emphasizes investments in particular industries or market sectors, the Fund will be subject to a greater degree to any market price movements, regulatory or technological change, economic conditions or other developments affecting those issuers or companies in those industries or market sectors. Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. Expense Risk. Your actual costs of investing in the Fund may be higher than the expenses shown in "Annual Fund Operating Expenses" 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. These and other risks are discussed in more detail later in this prospectus or in the statement of additional information. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 105% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, under normal circumstances, invests at least 80% of its assets in equity and equity related securities of U.S. and non-U.S. companies with market capitalizations at the time of initial purchase within the range of those in the Russell Midcap Value Index ("mid cap companies") that are publicly traded on a U.S. securities market. The market capitalization range of the Index changes constantly, and as a result, the capitalization of mid cap companies in which the Fund will invest will also change. As of September 30, 2012, the market capitalization range of the Index was approximately $300 million to $18.7 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, securities convertible into common stock, and warrants on common stock. The Adviser evaluates investment opportunities for the Fund using a proprietary value-oriented process that seeks to identify companies characterized by three attributes: change, neglect and relative valuation. The Adviser seeks to identify those changes that are material to a company's operations, outlook and prospects while also identifying companies that it believes have been neglected by other investors. The Adviser utilizes a primarily qualitative research process focused on these attributes to identify and invest in relatively undervalued companies. These factors formulate the Adviser's investment case for each company under consideration for investment. An important function of the Adviser's investment process is to set a price target at which the security will be sold, provided that there has been no fundamental change in the investment case. The Adviser monitors each security held by the Fund to determine if the security continues to act in accordance with the Adviser's initial assessment. Ordinarily, once the Adviser believes that an investment case has realized its anticipated prospects, the security will be sold. Additionally, the security would typically be sold if the identified change does not have the expected impact on earnings and cash flow of the company or a company's fundamentals deteriorate, or due to other market conditions that would cause the Adviser to believe a sale would be advisable.
Risk [Heading]	rr_RiskHeading	PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	It is possible to lose money by investing in the Fund. There is no guarantee that the stock market or the stocks the Fund buys will increase in value. The following is a summary description of certain risks of investing in the Fund. Market Risk. Stock markets are volatile and can decline significantly in response to adverse issuer, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. When market prices fall, the value of your investment will go down. 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. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. Whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, these events could negatively affect the value and liquidity of the Fund's investments. The Fund may experience a substantial or complete loss on any individual security. In addition, legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time. Company Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole. This may result from a wide variety of factors that affect particular companies or industries, including changes in market demand for particular goods and services, increases in costs of supply, changes in management, increased competition and changes in regulatory environment. Value Investing Risk. Value stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time. The Adviser may be incorrect when it decides that a stock is undervalued by the market. Portfolio Selection Risk. The value of your investment may decrease if the Adviser's judgment about the attractiveness, value of, or market trends affecting a particular security, industry or sector, country or region, or about market movements, is incorrect. Risks of Mid Cap Companies. Compared to mutual funds that focus exclusively on large capitalization companies, the Fund may be more volatile because it invests in mid capitalization companies. Mid capitalization companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Risks of Foreign Investments. Investing in foreign securities involves special risks that can increase the potential for losses. These risks may include nationalization or expropriation of assets, illiquid foreign securities markets, confiscatory taxation, foreign withholding taxes, imposition of currency controls or restrictions, natural disasters and political, economic or social instability. Because many foreign markets are smaller, less liquid and more volatile, the Fund may not be able to sell portfolio securities at times, in amounts and at prices it considers reasonable. In some foreign countries, less information is available about issuers and markets. Foreign markets may offer less protection to investors. Foreign stocks can fluctuate more widely in price than comparable U.S. stocks, and they may also be less liquid. Currency fluctuations could erase investment gains or add to investment losses. Focus Risk. To the extent that the Fund invests in a smaller number of issuers or emphasizes investments in particular industries or market sectors, the Fund will be subject to a greater degree to any market price movements, regulatory or technological changes, economic conditions or other developments affecting those issuers or companies in those industries or market sectors. Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. Expense Risk. Your actual costs of investing in the Fund may be higher than the expenses shown in "Annual Fund Operating Expenses" 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. These and other risks are discussed in more detail later in this prospectus or in the statement of additional information. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, under normal circumstances, invests at least 80% of its assets in equity and equity related securities of U.S. and non-U.S. companies with market capitalizations at the time of initial purchase within the range of those in the Russell 2500 Value Index or in the S&P Mid Cap 400 Value Index (together, "small/mid cap companies") that are publicly traded on a U.S. securities market. The market capitalization ranges of the Indices change constantly, and as a result, the capitalization of small/mid cap companies in which the Fund will invest will also change. As of September 30, 2012, the market capitalization range of the Russell 2500 Value Index was approximately $45 million to $8.5 billion, and the market capitalization range of the S&P Mid Cap 400 Value Index was approximately $237 million to $14.7 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, securities convertible into common stock, and warrants on common stock. The Adviser evaluates investment opportunities for the Fund using a proprietary value-oriented process that seeks to identify companies characterized by three attributes: change, neglect and relative valuation. The Adviser seeks to identify those changes that are material to a company's operations, outlook and prospects while also identifying companies that it believes have been neglected by other investors. The Adviser utilizes a primarily qualitative research process focused on these attributes to identify and invest in relatively undervalued companies. These factors formulate the Adviser's investment case for each company under consideration for investment. An important function of the Adviser's investment process is to set a price target at which the security will be sold, provided that there has been no fundamental change in the investment case. The Adviser monitors each security held by the Fund to determine if the security continues to act in accordance with the Adviser's initial assessment. Ordinarily, once the Adviser believes that an investment case has realized its anticipated prospects, the security will be sold. Additionally, the security would typically be sold if the identified change does not have the expected impact on earnings and cash flow of the company or a company's fundamentals deteriorate, or due to other market conditions that would cause the Adviser to believe a sale would be advisable.
Risk [Heading]	rr_RiskHeading	PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	It is possible to lose money by investing in the Fund. There is no guarantee that the stock market or the stocks the Fund buys will increase in value. The following is a summary description of certain risks of investing in the Fund. Market Risk. Stock markets are volatile and can decline significantly in response to adverse issuer, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. When market prices fall, the value of your investment will go down. 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. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. Whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, these events could negatively affect the value and liquidity of the Fund's investments. The Fund may experience a substantial or complete loss on any individual security. In addition, legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time. Company Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole. This may result from a wide variety of factors that affect particular companies or industries, including changes in market demand for particular goods and services, increases in costs of supply, changes in management, increased competition and changes in regulatory environment. Value Investing Risk. Value stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time. The Adviser may be incorrect when it decides that a stock is undervalued by the market. Portfolio Selection Risk. The value of your investment may decrease if the Adviser's judgment about the attractiveness, value of, or market trends affecting a particular security, industry or sector, country or region, or about market movements, is incorrect. Risks of Small and Mid Cap Companies. Compared to mutual funds that focus exclusively on large capitalization companies, the Fund may be more volatile because it invests in small and/or mid capitalization companies. Small and mid capitalization companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Securities of smaller companies may have limited liquidity and may be difficult to value or to sell at an advantageous time or without a substantial drop in price. Risks of Foreign Investments. Investing in foreign securities involves special risks that can increase the potential for losses. These risks may include nationalization or expropriation of assets, illiquid foreign securities markets, confiscatory taxation, foreign withholding taxes, imposition of currency controls or restrictions, natural disasters and political, economic or social instability. Because many foreign markets are smaller, less liquid and more volatile, the Fund may not be able to sell portfolio securities at times, in amounts and at prices it considers reasonable. In some foreign countries, less information is available about issuers and markets. Foreign markets may offer less protection to investors. Foreign stocks can fluctuate more widely in price than comparable U.S. stocks, and they may also be less liquid. Currency fluctuations could erase investment gains or add to investment losses. Focus Risk. To the extent that the Fund invests in a smaller number of issuers or emphasizes investments in particular industries or market sectors, the Fund will be subject to a greater degree to any market price movements, regulatory or technological changes, economic conditions or other developments affecting those issuers or companies in those industries or market sectors. Portfolio Turnover Risk.If the Fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. Expense Risk. Your actual costs of investing in the Fund may be higher than the expenses shown in "Annual Fund Operating Expenses" 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. These and other risks are discussed in more detail later in this prospectus or in the statement of additional information. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

CRM MID CAP VALUE FUND

INVESTMENT OBJECTIVE

CRM Mid Cap Value Fund seeks long-term capital appreciation.

FEES AND EXPENSES

This table sets forth 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)

Total Annual Fund Operating Expenses	[1]	1.03%	0.82%

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 below shows what
you would pay if you invested $10,000 over the various time periods indicated.
The Example assumes that you reinvested all dividends and other distributions;
the average annual return was 5%; the Fund's total operating expenses are
charged and remain the same over the time periods; and you redeemed all of your
investment at the end of each time period.

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

Expense Example CRM MID CAP VALUE FUND (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Investor Shares	105	328	569	1,259
Institutional Shares	84	262	455	1,014

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.
During the most recent fiscal year, the Fund's portfolio turnover rate was 105%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in
equity and equity related securities of U.S. and non-U.S. companies with market
capitalizations at the time of initial purchase within the range of those in
the Russell Midcap Value Index ("mid cap companies") that are publicly traded
on a U.S. securities market. The market capitalization range of the Index
changes constantly, and as a result, the capitalization of mid cap companies
in which the Fund will invest will also change. As of September 30, 2012, the
market capitalization range of the Index was approximately $300 million to
$18.7 billion. For purposes of the 80% investment policy, equity and equity
related securities include: common and preferred stocks, securities convertible
into common stock, and warrants on common stock.

The Adviser evaluates investment opportunities for the Fund using a proprietary
value-oriented process that seeks to identify companies characterized by three
attributes: change, neglect and relative valuation. The Adviser seeks to
identify those changes that are material to a company's operations, outlook and
prospects while also identifying companies that it believes have been neglected
by other investors. The Adviser utilizes a primarily qualitative research process
focused on these attributes to identify and invest in relatively undervalued
companies. These factors formulate the Adviser's investment case for each company
under consideration for investment. An important function of the Adviser's
investment process is to set a price target at which the security will be sold,
provided that there has been no fundamental change in the investment case. The
Adviser monitors each security held by the Fund to determine if the security
continues to act in accordance with the Adviser's initial assessment. Ordinarily,
once the Adviser believes that an investment case has realized its anticipated
prospects, the security will be sold. Additionally, the security would typically
be sold if the identified change does not have the expected impact on earnings and
cash flow of the company or a company's fundamentals deteriorate, or due to other
market conditions that would cause the Adviser to believe a sale would be advisable.

PRINCIPAL INVESTMENT RISKS

It is possible to lose money by investing in the Fund. There is no guarantee
that the stock market or the stocks the Fund buys will increase in value. The
following is a summary description of certain risks of investing in the Fund.

Market Risk. Stock markets are volatile and can decline significantly in
response to adverse issuer, regulatory, market or economic developments.
Different parts of the U.S. market and different markets around the world can
react differently to these developments. When market prices fall, the value of
your investment will go down. 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. Further
defaults or restructurings by governments and others of their debt could have
additional adverse effects on economies, financial markets and asset valuations
around the world. Whether or not the Fund invests in securities of issuers
located in or with significant exposure to countries experiencing economic and
financial difficulties, these events could negatively affect the value and
liquidity of the Fund's investments. The Fund may experience a substantial or
complete loss on any individual security. In addition, legislation recently
enacted in the U.S. calls for changes in many aspects of financial regulation.
The impact of the legislation on the markets, and the practical implications for
market participants, may not be fully known for some time.

Company Risk. The value of an individual security or particular type of security
can be more volatile than the market as a whole and can perform differently from
the market as a whole. This may result from a wide variety of factors that
affect particular companies or industries, including changes in market demand
for particular goods and services, increases in costs of supply, changes in
management, increased competition and changes in regulatory environment.

Value Investing Risk. Value stocks can perform differently from the market as a
whole and other types of stocks and can continue to be undervalued by the market
for long periods of time. The Adviser may be incorrect when it decides that a
stock is undervalued by the market.

Portfolio Selection Risk. The value of your investment may decrease if the
Adviser's judgment about the attractiveness, value of, or market trends affecting
a particular security, industry or sector, country or region, or about market
movements, is incorrect.

Risks of Mid Cap Companies. Compared to mutual funds that focus exclusively on
large capitalization companies, the Fund may be more volatile because it invests
in mid capitalization companies. Mid capitalization companies are more likely to
have more limited product lines, fewer capital resources and less depth of
management than larger companies.

Risks of Foreign Investments. Investing in foreign securities involves special
risks that can increase the potential for losses. These risks may include
nationalization or expropriation of assets, illiquid foreign securities markets,
confiscatory taxation, foreign withholding taxes, imposition of currency
controls or restrictions, natural disasters and political, economic or social
instability. Because many foreign markets are smaller, less liquid and more
volatile, the Fund may not be able to sell portfolio securities at times, in
amounts and at prices it considers reasonable. In some foreign countries, less
information is available about issuers and markets. Foreign markets may offer
less protection to investors. Foreign stocks can fluctuate more widely in price
than comparable U.S. stocks, and they may also be less liquid. Currency
fluctuations could erase investment gains or add to investment losses.

Focus Risk. To the extent that the Fund invests in a smaller number of issuers
or emphasizes investments in particular industries or market sectors, the Fund
will be subject to a greater degree to any market price movements, regulatory or
technological changes, economic conditions or other developments affecting those
issuers or companies in those industries or market sectors.

Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur additional
operating expenses, which would reduce performance, and could cause shareowners to
incur a higher level of taxable income or capital gains.

Expense Risk. Your actual costs of investing in the Fund may be higher than the
expenses shown in "Annual Fund Operating Expenses" 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.

These and other risks are discussed in more detail later in this prospectus or
in the statement of additional information.

An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

CRM ALL CAP VALUE FUND

INVESTMENT OBJECTIVE

CRM All Cap Value Fund seeks long-term capital appreciation.

FEES AND EXPENSES

This table sets forth 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 CRM All Cap Value Fund		Investor Shares	Institutional Shares

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 below shows what
you would pay if you invested $10,000 over the various time periods indicated.
The Example assumes that you reinvested all dividends and other distributions;
the average annual return was 5%; the Fund's total operating expenses
(reflecting applicable contractual fee waivers and expense reimbursement
arrangements) are charged and remain the same over the time periods; and
you redeemed all of your investment at the end of each time period.

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

Investor Shares	154	494	858	1,882
Institutional Shares	128	417	726	1,606

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.
During the most recent fiscal year, the Fund's portfolio turnover rate was 145%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in
equity and equity related securities of U.S. and non-U.S. companies that are
publicly traded on a U.S. securities market. There are no limits on the market
capitalizations of the companies in which the Fund may invest. For purposes of
the 80% investment policy, equity and equity related securities include: common
and preferred stocks, securities convertible into common stock, and warrants on
common stock.

The Adviser evaluates investment opportunities for the Fund using a proprietary
value-oriented process that seeks to identify companies characterized by three
attributes: change, neglect and relative valuation. The Adviser seeks to identify
those changes that are material to a company's operations, outlook and prospects
while also identifying companies that it believes have been neglected by other
investors. The Adviser utilizes a primarily qualitative research process focused
on these attributes to identify and invest in relatively undervalued companies.
These factors formulate the Adviser's investment case for each company under
consideration for investment. An important function of the Adviser's investment
process is to set a price target at which the security will be sold, provided
that there has been no fundamental change in the investment case. The Adviser
monitors each security held by the Fund to determine if the security continues
to act in accordance with the Adviser's initial assessment. Ordinarily, once the
Adviser believes that an investment case has realized its anticipated prospects,
the security will be sold. Additionally, the security would typically be sold if
the identified change does not have the expected impact on earnings and cash flow
of the company or a company's fundamentals deteriorate, or due to other market
conditions that would cause the Adviser to believe a sale would be advisable.

PRINCIPAL INVESTMENT RISKS

It is possible to lose money by investing in the Fund. There is no guarantee
that the stock market or the stocks the Fund buys will increase in value. The
following is a summary description of certain risks of investing in the Fund.

Market Risk. Stock markets are volatile and can decline significantly in response
to adverse issuer, regulatory, market or economic developments. Different parts
of the U.S. market and different markets around the world can react differently
to these developments. When market prices fall, the value of your investment
will go down. 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. Further defaults or
restructurings by governments and others of their debt could have additional
adverse effects on economies, financial markets and asset valuations around the
world. Whether or not the Fund invests in securities of issuers located in or
with significant exposure to countries experiencing economic and financial
difficulties, these events could negatively affect the value and liquidity of
the Fund's investments. The Fund may experience a substantial or complete loss
on any individual security. In addition, legislation recently enacted in the
U.S. calls for changes in many aspects of financial regulation. The impact of
the legislation on the markets, and the practical implications for market
participants, may not be fully known for some time.

Company Risk. The value of an individual security or particular type of security
can be more volatile than the market as a whole and can perform differently from
the market as a whole. This may result from a wide variety of factors that affect
particular companies or industries, including changes in market demand for
particular goods and services, increases in costs of supply, changes in management,
increased competition and changes in regulatory environment.

Value Investing Risk. Value stocks can perform differently from the market as a
whole and other types of stocks and can continue to be undervalued by the market
for long periods of time. The Adviser may be incorrect when it decides that a
stock is undervalued by the market.

Portfolio Selection Risk. The value of your investment may decrease if the
Adviser's judgment about the attractiveness, value of, or market trends affecting
a particular security, industry or sector, country or region, or about market
movements, is incorrect.

Risks of Small and Mid Cap Companies. Compared to mutual funds that focus
exclusively on large capitalization companies, the Fund may be more volatile
because it also invests in small and/or mid capitalization companies. Small and
mid capitalization companies are more likely to have more limited product lines,
fewer capital resources and less depth of management than larger companies.
Securities of smaller companies may have limited liquidity and may be difficult
to value or to sell at an advantageous time or without a substantial drop in
price.

Risks of Foreign Investments. Investing in foreign securities involves special
risks that can increase the potential for losses. These risks may include
nationalization or expropriation of assets, illiquid foreign securities markets,
confiscatory taxation, foreign withholding taxes, imposition of currency
controls or restrictions, natural disasters and political, economic or social
instability. Because many foreign markets are smaller, less liquid and more
volatile, the Fund may not be able to sell portfolio securities at times, in
amounts and at prices it considers reasonable. In some foreign countries, less
information is available about issuers and markets. Foreign markets may offer
less protection to investors. Foreign stocks can fluctuate more widely in price
than comparable U.S. stocks, and they may also be less liquid. Currency
fluctuations could erase investment gains or add to investment losses.

Focus Risk. To the extent that the Fund invests in a smaller number of issuers
or emphasizes investments in particular industries or market sectors, the Fund
will be subject to a greater degree to any market price movements, regulatory or
technological changes, economic conditions or other developments affecting those
issuers or companies in those industries or market sectors.

Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur
additional operating expenses, which would reduce performance, and could cause
shareowners to incur a higher level of taxable income or capital gains.

Expense Risk. Your actual costs of investing in the Fund may be higher than the
expenses shown in "Annual Fund Operating Expenses" 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.

These and other risks are discussed in more detail later in this prospectus or
in the statement of additional information.

An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The bar chart and the average annual total return table below illustrate the risks
and volatility of an investment in the Fund. The bar chart shows changes in the
Fund's performance from calendar year to calendar year for Institutional Shares.
The table shows how the Fund's average annual total returns for one year, five
years and since inception, both before and after taxes, compare with those of the
Russell 3000 Value Index and the Russell 3000 Index, two broad-based measures of
market performance. Total returns would have been lower had certain fees and
expenses not been waived. The Fund makes updated performance information available
at the Fund's website, www.crmfunds.com/performance_daily.aspx, or at the following
telephone number: 800-CRM-2883. Of course, the Fund's past performance, both before
and after taxes, does not necessarily indicate how the Fund will perform in the future.

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, under normal circumstances, invests at least 80% of its assets in equity and equity related securities of U.S. and foreign companies. The Fund normally invests in the securities of companies that are tied economically to at least 10 countries, including the U.S. The Fund may invest in companies located in developed and emerging markets. Emerging markets include countries that have an emerging stock market as defined by Standard & Poor's, Inc., countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar emerging characteristics. The Fund may at any one time invest all or substantially all of its assets in foreign companies and at another time invest substantially in U.S. companies, although, under normal market conditions, it is expected that a majority of the Fund's assets will be invested in foreign companies. The Fund may invest in companies of any size. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, securities convertible into common stock, and warrants on common stock.

The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time. Company Risk.

The value of your investment may decrease if the Adviser's judgment about the attractiveness, value of, or market trends affecting a particular security, industry or sector, country or region, or about market movements, is incorrect. Risks of Foreign Investments. Investing in foreign securities involves special risks that can increase the potential for losses. These risks may include nationalization or expropriation of assets, illiquid foreign securities markets, confiscatory taxation, foreign withholding taxes, natural disasters and political, economic or social instability. Because many foreign markets are smaller, less liquid and more volatile, the Fund may not be able to sell portfolio securities at times, in amounts and at prices it considers reasonable. In some foreign countries, less information is available about issuers and markets. Foreign markets may offer less protection to investors. Foreign stocks can fluctuate more widely in price than comparable U.S. stocks, and they may also be less liquid. Currency Risk. The Fund generally invests in securities denominated in foreign currencies, and could experience gains or losses solely on changes in the exchange rate between foreign currencies and the U.S. dollar. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, and the imposition of currency controls or restrictions and speculation. Emerging Markets Risk.The risks of investing in foreign securities are generally greater in emerging markets, or to the extent that the Fund invests significantly in one region or country. The extent of economic development, political stability, market depth, infrastructure, capitalization and regulatory oversight can be less than in more developed markets. The economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may experience rising interest rates, or, more significantly, rapid inflation or hyperinflation. Risks of Small and Mid Cap Companies. Compared to mutual funds that focus exclusively on large capitalization companies, the Fund may be more volatile because it also invests in small and/or mid capitalization companies. Small and mid capitalization companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. Securities of smaller companies may have limited liquidity and may be difficult to value or sell at advantageous time or without a substantial drop in price. Focus Risk. To the extent that the Fund invests in a smaller number of issuers or emphasizes investments in particular industries or market sectors, the Fund will be subject to a greater degree to any market price movements, regulatory or technological changes, economic conditions or other developments affecting those issuers or companies in those industries or market sectors. Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur additional operating expenses, which would reduce performance, and could cause shareowners to incur a higher level of taxable income or capital gains. Expense Risk. Your actual costs of investing in the Fund may be higher than the expenses shown in "Annual Fund Operating Expenses" 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.

CRM LARGE CAP OPPORTUNITY FUND

INVESTMENT OBJECTIVE

CRM Large Cap Opportunity Fund seeks long-term capital appreciation.

FEES AND EXPENSES

This table sets forth 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 CRM LARGE CAP OPPORTUNITY FUND		Investor Shares	Institutional Shares
Management Fees		0.75%	0.75%

Other Miscellaneous Expenses		0.33%	0.34%
Total Other Expenses		0.58%	0.34%

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 below shows what
you would pay if you invested $10,000 over the various time periods indicated.
The Example assumes that you reinvested all dividends and other distributions;
the average annual return was 5%; the Fund's total operating expenses (reflecting
applicable contractual fee waivers and expense reimbursement arrangements) are
charged and remain the same over the time periods; and you redeemed all of your
investment at the end of each time period.

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

Expense Example CRM LARGE CAP OPPORTUNITY FUND (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Investor Shares	118	407	717	1,597
Institutional Shares	93	331	588	1,323

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.
During the most recent fiscal year, the Fund's portfolio turnover rate was 126%
of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in
equity and equity related securities of U.S. and non-U.S. companies with market
capitalizations at the time of initial purchase within the range of those in the
Russell 1000 Value Index ("large cap companies") that are publicly traded on a
U.S. securities market. The market capitalization range of the Index changes
constantly, and as a result, the capitalization of large cap companies in which
the Fund will invest will also change. As of September 30, 2012, the market
capitalization range of the Index was approximately $300 million to $427.6 billion.
For purposes of the 80% investment policy, equity and equity related securities
include: common and preferred stocks, securities convertible into common stock,
and warrants on common stock.

The Adviser evaluates investment opportunities for the Fund using a proprietary
value-oriented process that seeks to identify companies characterized by three
attributes: change, neglect and relative valuation. The Adviser seeks to identify
those changes that are material to a company's operations, outlook and prospects
while also identifying companies that it believes have been neglected by other
investors. The Adviser utilizes a primarily qualitative research process focused
on these attributes to identify and invest in relatively undervalued companies.
These factors formulate the Adviser's investment case for each company under
consideration for investment. An important function of the Adviser's investment
process is to set a price target at which the security will be sold, provided
that there has been no fundamental change in the investment case. The Adviser
monitors each security held by the Fund to determine if the security continues
to act in accordance with the Adviser's initial assessment. Ordinarily, once the
Adviser believes that an investment case has realized its anticipated prospects,
the security will be sold. Additionally, the security would typically be sold if
the identified change does not have the expected impact on earnings and cash flow
of the company or a company's fundamentals deteriorate, or due to other market
conditions that would cause the Adviser to believe a sale would be advisable.

PRINCIPAL INVESTMENT RISKS

It is possible to lose money by investing in the Fund. There is no guarantee
that the stock market or the stocks the Fund buys will increase in value. The
following is a summary description of certain risks of investing in the Fund.
  
Market Risk. Stock markets are volatile and can decline significantly in
response to adverse issuer, regulatory, market or economic developments.
Different parts of the U.S. market and different markets around the world can
react differently to these developments. When market prices fall, the value of
your investment will go down. 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. Further
defaults or restructurings by governments and others of their debt could have
additional adverse effects on economies, financial markets and asset valuations
around the world. Whether or not the Fund invests in securities of issuers
located in or with significant exposure to countries experiencing economic and
financial difficulties, these events could negatively affect the value and
liquidity of the Fund's investments. The Fund may experience a substantial or
complete loss on any individual security. In addition, legislation recently
enacted in the U.S. calls for changes in many aspects of financial regulation.
The impact of the legislation on the markets, and the practical implications
for market participants, may not be fully known for some time.
  
Company Risk. The value of an individual security or particular type of security
can be more volatile than the market as a whole and can perform differently from
the market as a whole. This may result from a wide variety of factors that
affect particular companies or industries, including changes in market demand
for particular goods and services, increases in costs of supply, changes in
management, increased competition and changes in regulatory environment.

Value Investing Risk. Value stocks can perform differently from the market as a
whole and other types of stocks and can continue to be undervalued by the market
for long periods of time. The Adviser may be incorrect when it decides that a
stock is undervalued by the market.
  
Portfolio Selection Risk. The value of your investment may decrease if the
Adviser's judgment about the attractiveness, value of, or market trends
affecting a particular security, industry or sector, country or region, or
about market movements, is incorrect.
  
Risks of Foreign Investments. Investing in foreign securities involves special
risks that can increase the potential for losses. These risks may include
nationalization or expropriation of assets, illiquid foreign securities markets,
confiscatory taxation, foreign withholding taxes, imposition of currency
controls or restrictions, natural disasters and political, economic or social
instability. Because many foreign markets are smaller, less liquid and more
volatile, the Fund may not be able to sell portfolio securities at times, in
amounts and at prices it considers reasonable. In some foreign countries, less
information is available about issuers and markets. Foreign markets may offer
less protection to investors. Foreign stocks can fluctuate more widely in price
than comparable U.S. stocks, and they may also be less liquid. Currency
fluctuations could erase investment gains or add to investment losses.
  
Focus Risk. To the extent that the Fund invests in a smaller number of issuers
or emphasizes investments in particular industries or market sectors, the Fund
will be subject to a greater degree to any market price movements, regulatory or
technological changes, economic conditions or other developments affecting those
issuers or companies in those industries or market sectors.
  
Portfolio Turnover Risk. If the Fund does a lot of trading, it may incur additional
operating expenses, which would reduce performance, and could cause shareowners to
incur a higher level of taxable income or capital gains.
  
Expense Risk. Your actual costs of investing in the Fund may be higher than the
expenses shown in "Annual Fund Operating Expenses" 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.
  
These and other risks are discussed in more detail later in this prospectus or
in the statement of additional information.
  
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE INFORMATION

The bar chart and the average annual total return table below illustrate
the risks and volatility of an investment in the Fund. The bar chart shows
changes in the Fund's performance from calendar year to calendar year for
Institutional Shares. The table shows how the Fund's average annual total
returns for one year, five years and since inception, both before and after
taxes, compare with those of the Russell 1000 Value Index and the Russell
1000 Index, two broad-based measures of market performance. Total returns
would have been lower had certain fees and expenses not been waived. The
Fund makes updated performance information available at the Fund's website,
www.crmfunds.com/performance_daily.aspx, or at the following telephone number:
800-CRM-2883. Of course, the Fund's past performance, both before and after
taxes, does not necessarily indicate how the Fund will perform in the future.
