CRM SMALL CAP VALUE 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	INSTITUTIONAL
Management Fees		0.75%	0.75%
Distribution (12b-1) Fees		none	none
Shareholder Servicing Fee		0.25%	none
Other Miscellaneous Expenses		0.13%	0.14%
Total Other Expenses		0.38%	0.14%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1]	1.14%	0.90%

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 ($)	1 Year	3 Years	5 Years	10 Years
INVESTOR	116	362	628	1,386
INSTITUTIONAL	92	287	498	1,108

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 49% 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 28, 2018, the market capitalization range of the Index was approximately $75 million to $6 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, 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. The Adviser’s process is focused not only on building the investment case, but also on understanding how the case might deteriorate. The Adviser’s sell discipline is ultimately dependent upon the written investment case for the stock. A position generally will be sold when one or more of the following occurs: (i) an established price target is approaching or is attained, implying the stock has reached an estimation of fair valuation; (ii) a factor in the initial investment thesis has deteriorated causing the Adviser to reassess the potential for the company; or (iii) the Adviser identifies what it believes is a more promising investment opportunity. After a decision to sell is made, the investment generally is replaced by either a new idea or existing holdings which the Adviser believes offers greater upside.

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.

Market Risk. Stock markets are volatile and can decline significantly in response to adverse issuer, industry, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. If the market prices of the securities owned by the Fund fall, the value of your investment will go down. U.S. and non-U.S. governments and central banks have provided significant support to financial markets, including by keeping interest rates at historically low levels. The U.S. Federal Reserve is reducing its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries and other events affecting global markets, such as the United Kingdom’s expected exit from the European Union (or Brexit) are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes 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 or be out of favor for long periods of time. The Adviser may be incorrect when it determines 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, terrorism 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 costs, as well as taxable income or capital gains.

Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the Adviser and/or their service providers (including, but not limited to, the Fund’s transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions.

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, five and ten years, both before and after taxes, compare with those of the Russell 2000 Value Index and the Russell 2000 Index, two broad based measures of market performance. The Fund makes updated performance information available at the Fund’s website, www.crmfunds.com/funds-overview/performance-overview/, 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. In that case, you may be taxed when you take a distribution from such plan, depending on the type of plan, the circumstances of your distribution and other factors. 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.

CRM SMALL/MID CAP VALUE FUND

CRM 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	INSTITUTIONAL
Management Fees		0.75%	0.75%
Distribution (12b-1) Fees		none	none
Shareholder Servicing Fee		0.25%	none
Other Miscellaneous Expenses		0.13%	0.16%
Total Other Expenses		0.38%	0.16%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1]	1.14%	0.92%

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 ($)	1 Year	3 Years	5 Years	10 Years
INVESTOR	116	362	628	1,386
INSTITUTIONAL	94	293	509	1,131

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 48% 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 28, 2018, the market capitalization range of the Russell 2500 Value Index was approximately $75 million to $14 billion, and the market capitalization range of the S&P Mid Cap 400 Value Index was approximately $1 billion to $12 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, 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. The Adviser’s process is focused not only on building the investment case, but also on understanding how the case might deteriorate. The Adviser’s sell discipline is ultimately dependent upon the written investment case for the stock. A position generally will be sold when one or more of the following occurs: (i) an established price target is approaching or is attained, implying the stock has reached an estimation of fair valuation; (ii) a factor in the initial investment thesis has deteriorated causing the Adviser to reassess the potential for the company; or (iii) the Adviser identifies what it believes is a more promising investment opportunity. After a decision to sell is made, the investment generally is replaced by either a new idea or existing holdings which the Adviser believes offers greater upside.

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, industry, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. If the market prices of the securities owned by the Fund fall, the value of your investment will go down. U.S. and non-U.S. governments and central banks have provided significant support to financial markets, including by keeping interest rates at historically low levels. The U.S. Federal Reserve is reducing its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries and other events affecting global markets, such as the United Kingdom’s expected exit from the European Union (or Brexit) are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes 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 or be out of favor for long periods of time. The Adviser may be incorrect when it determines 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, terrorism 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 costs, as well as income or capital gains.

Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the Adviser and/or their service providers (including, but not limited to, the Fund’s transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions.

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, five and ten years, 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. 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/funds-overview/performance-overview/, 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. In that case, you may be taxed when you take a distribution from such plan, depending on the type of plan, the circumstances of your distribution and other factors. After-tax returns are shown only for Institutional Shares. After-tax returns for Investor Shares will vary.

CRM MID CAP VALUE FUND

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)

Annual Fund Operating Expenses - CRM MID CAP VALUE FUND		INVESTOR	INSTITUTIONAL
Management Fees		0.75%	0.75%
Distribution (12b-1) fees		none	none
Shareholder Servicing Fee		0.25%	none
Other Miscellaneous Expenses		0.11%	0.16%
Total Other Expenses		0.36%	0.16%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1]	1.12%	0.92%

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 ($)	1 Year	3 Years	5 Years	10 Years
INVESTOR	114	356	617	1,363
INSTITUTIONAL	94	293	509	1,131

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 58% 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 28, 2018, the market capitalization range of the Index was approximately $604 million to $75 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, 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. The Adviser’s process is focused not only on building the investment case, but also on understanding how the case might deteriorate. The Adviser’s sell discipline is ultimately dependent upon the written investment case for the stock. A position generally will be sold when one or more of the following occurs: (i) an established price target is approaching or is attained, implying the stock has reached an estimation of fair valuation; (ii) a factor in the initial investment thesis has deteriorated causing the Adviser to reassess the potential for the company; or (iii) the Adviser identifies what it believes is a more promising investment opportunity. After a decision to sell is made, the investment generally is replaced by either a new idea or existing holdings which the Adviser believes offers greater upside.

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, industry, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. If the market prices of the securities owned by the Fund fall, the value of your investment will go down. U.S. and non-U.S. governments and central banks have provided significant support to financial markets, including by keeping interest rates at historically low levels. The U.S. Federal Reserve is reducing its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries and other events affecting global markets, such as the United Kingdom’s expected exit from the European Union (or Brexit) are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes 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 or be out of favor for long periods of time. The Adviser may be incorrect when it determines 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, terrorism 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 costs, as well as taxable income or capital gains.

Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the Adviser and/or their service providers (including, but not limited to, the Fund’s transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions.

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, five and ten years, both before and after taxes, compare with those of the Russell Midcap Value Index and the Russell Midcap Index, two broad based measures of market performance. The Fund makes updated performance information available at the Fund’s website, www.crmfunds.com/funds-overview/performance-overview/, 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. In that case, you may be taxed when you take a distribution from such plan, depending on the type of plan, the circumstances of your distribution and other factors. After-tax returns are shown only for Institutional Shares. After-tax returns for Investor Shares will vary.

CRM LARGE CAP OPPORTUNITY FUND

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	INSTITUTIONAL
Management Fees		0.55%	0.55%
Distribution (12b-1) Fees		none	none
Shareholder Servicing Fee		0.25%	none
Other Miscellaneous Expenses		0.24%	0.24%
Total Other Expenses		0.49%	0.24%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1],[2]	1.05%	0.80%
Fee Waiver and Expense Reimbursement	[1]	(0.14%)	(0.14%)
Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement	[1],[2]	0.91%	0.66%

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 ($)	1 Year	3 Years	5 Years	10 Years
INVESTOR	93	320	566	1,270
INSTITUTIONAL	67	241	430	977

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 79% 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 28, 2018, the market capitalization range of the Index was approximately $604 million to $878 billion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, 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. The Adviser’s process is focused not only on building the investment case, but also on understanding how the case might deteriorate. The Adviser’s sell discipline is ultimately dependent upon the written investment case for the stock. A position generally will be sold when one or more of the following occurs: (i) an established price target is approaching or is attained, implying the stock has reached an estimation of fair valuation; (ii) a factor in the initial investment thesis has deteriorated causing the Adviser to reassess the potential for the company; or (iii) the Adviser identifies what it believes is a more promising investment opportunity. After a decision to sell is made, the investment generally is replaced by either a new idea or existing holdings which the Adviser believes offers greater upside.

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, industry, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. If the market prices of the securities owned by the Fund fall, the value of your investment will go down. U.S. and non-U.S. governments and central banks have provided significant support to financial markets, including by keeping interest rates at historically low levels. The U.S. Federal Reserve is reducing its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries and other events affecting global markets, such as the United Kingdom’s expected exit from the European Union (or Brexit) are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes 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 or be out of favor for long periods of time. The Adviser may be incorrect when it determines 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 Large Cap Companies. Large capitalization companies may fall out of favor with investors based on market and economic conditions. In addition, larger companies may not be able to attain the high growth rates of successful smaller companies and may be less capable of responding quickly to competitive challenges and industry changes. As a result, the Fund’s value may not rise as much as, or may fall more than, the value of funds that focus on companies with smaller market capitalizations.

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, terrorism 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 costs, as well as taxable income or capital gains.

Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the Adviser and/or their service providers (including, but not limited to, the Fund’s transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions.

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, five and ten years, 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/funds-overview/performance-overview/, 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. In that case, you may be taxed when you take a distribution from such plan, depending on the type of plan, the circumstances of your distribution and other factors. After-tax returns are shown only for Institutional Shares. After-tax returns for Investor Shares will vary.

[1] 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 0.90% and 0.65% of average daily net assets of Investor Shares and Institutional Shares, respectively. These expense limitations are in effect until November 1, 2019. 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 All Cap Value Fund

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
Management Fees		0.95%	0.95%
Distribution (12b-1) Fees		none	none
Shareholder Servicing Fee		0.25%	none
Other Miscellaneous Expenses		0.73%	0.73%
Total Other Expenses		0.98%	0.73%
Acquired Fund Fees and Expenses		0.01%	0.01%
Total Annual Fund Operating Expenses	[1],[2]	1.94%	1.69%
Fee Waiver and Expense Reimbursement	[1]	(0.43%)	(0.43%)
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 All Cap Value Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Investor Shares	154	568	1,007	2,230
Institutional Shares	128	491	877	1,962

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 72% 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, 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. The Adviser’s process is focused not only on building the investment case, but also on understanding how the case might deteriorate. The Adviser’s sell discipline is ultimately dependent upon the written investment case for the stock. A position generally will be sold when one or more of the following occurs: (i) an established price target is approaching or is attained, implying the stock has reached an estimation of fair valuation; (ii) a factor in the initial investment thesis has deteriorated causing the Adviser to reassess the potential for the company; or (iii) the Adviser identifies what it believes is a more promising investment opportunity. After a decision to sell is made, the investment generally is replaced by either a new idea or existing holdings which the Adviser believes offers greater upside.

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, industry, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. If the market prices of the securities owned by the Fund fall, the value of your investment will go down. U.S. and non-U.S. governments and central banks have provided significant support to financial markets, including by keeping interest rates at historically low levels. The U.S. Federal Reserve is reducing its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries and other events affecting global markets, such as the United Kingdom’s expected exit from the European Union (or Brexit) are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes 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 or be out of favor for long periods of time. The Adviser may be incorrect when it determines 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 Large Cap Companies. Large capitalization companies may fall out of favor with investors based on market and economic conditions. In addition, larger companies may not be able to attain the high growth rates of successful smaller companies and may be less capable of responding quickly to competitive challenges and industry changes. As a result, the Fund’s value may not rise as much as, or may fall more than, the value of funds that focus on companies with smaller market capitalizations.

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, terrorism 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 costs, as well as taxable income or capital gains.

Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the Adviser and/or their service providers (including, but not limited to, the Fund’s transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions.

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, five and ten years, 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/funds-overview/performance-overview/, 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. In that case, you may be taxed when you take a distribution from such plan, depending on the type of plan, the circumstances of your distribution and other factors. After-tax returns are shown only for Institutional Shares. After-tax returns for Investor Shares will vary.

CRM LONG/SHORT OPPORTUNITIES FUND

CRM LONG/SHORT OPPORTUNITIES FUND

INVESTMENT OBJECTIVE

The 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 LONG/SHORT OPPORTUNITIES FUND INSTITUTIONAL SHARES
Management Fees	1.50%
Distribution (12b-1) Fees	none
Dividend Expense on Securities Sold Short and Interest Expense on Borrowings	1.20%
Remainder of Other Expenses	0.15%
Total Other Expenses	1.35%
Acquired Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses	2.86%	[1],[2]
Fee Waiver and Expense Reimbursement	(0.05%)	[1]
Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement	2.81%	[1],[2]

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	1 Year	3 Years	5 Years	10 Years
CRM LONG/SHORT OPPORTUNITIES FUND | INSTITUTIONAL SHARES | USD ($)	284	881	1,504	3,182

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 251% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund, under normal circumstances, invests at least 80% of its assets in long and short positions 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 S&P 500 Index 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 companies in which the Fund will invest will also change. As of September 28, 2018, the market capitalization range of the Index was from approximately $5 billion to $1.1 trillion. For purposes of the 80% investment policy, equity and equity related securities include: common and preferred stocks, and warrants on common stock. In applying this 80% investment policy, the assets of the Fund include both long and short positions and Fund borrowings.

The Fund will hold long equity securities that the Adviser has identified as undervalued and take short positions (through short sales) in equity securities that the Adviser has identified as overvalued or poised for underperformance. A short sale is a transaction in which the Fund sells a stock it does not own in anticipation of a decline in the market value of the stock, and then borrows the stock to make delivery to the buyer. The Fund may engage in short sales for hedging purposes or to attempt to increase the Fund’s return as a non-hedging strategy that may be considered speculative. Short selling may result in greater risk to the Fund because losses are potentially unlimited.

When the Fund takes a long position, it purchases the stock outright. When the Fund takes a short position, it sells a stock that it does not own and settles the sale by borrowing the same stock from a lender. To close out the short position, the Fund subsequently buys back the same stock in the market and returns it to the lender. The Fund makes money on a short position if the market price of the stock goes down after the short sale. Conversely, if the price of the stock goes up after the short sale, the Fund will lose money because it will have to pay more to replace the borrowed stock than it received when it sold the stock short. Short selling is a technique that may be considered speculative and involves risk beyond the amount of money invested.

The Adviser believes that a long/short strategy will enable the Fund to reflect the Adviser’s positive and negative views on individual stocks and to seek higher performance. If the Fund’s strategy succeeds, in rising markets, the Fund’s long positions will appreciate to a greater extent than the short positions, and in declining markets, the short positions will gain in value relative to the long positions. However, there can be no guarantee that this result will be achieved.

The Fund may, but is not required to, invest in derivative contracts, such as swaps and options on securities and securities indices, for a variety of purposes, including: in an attempt to hedge against adverse changes in the market price of securities, interest rates or currency exchange rates; as a substitute for purchasing or selling securities, including short sales; to attempt to increase the Fund’s return as a non-hedging strategy that may be considered speculative; to manage portfolio characteristics; and as a cash flow management technique. The Fund may choose not to make use of derivatives for a variety of reasons, and any use may be limited by applicable law and regulations. The Fund may also hold cash or other short-term investments.

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. The Adviser’s process is focused not only on building the investment case, but also on understanding how the case might deteriorate. The Adviser’s sell discipline is ultimately dependent upon the written investment case for the stock. A position generally will be sold when one or more of the following occurs: (i) an established price target is approaching or is attained, implying the stock has reached an estimation of fair valuation; (ii) a factor in the initial investment thesis has deteriorated causing the Adviser to reassess the potential for the company; or (iii) the Adviser identifies what it believes is a more promising investment opportunity. After a decision to sell is made, the investment generally is replaced by either a new idea or existing holdings which the Adviser believes offers greater upside. A short position may be closed out when a company’s fundamentals improve or expected underperformance fails to occur.

The Fund may borrow money from banks and using the proceeds to purchase additional securities to the extent permitted under the Investment Company Act of 1940, as amended (“1940 Act”).

In addition, for purposes of the Fund’s 80% investment policy, equity and equity related securities also include: (i) securities convertible into common stock (such as convertible preferred stock and convertible bonds) that are rated, at the time of initial purchase, in one of the three highest rating categories by a nationally recognized statistical rating organization (“NRSRO”) such as Moody’s Investor Services, Inc. (“Moody’s”) or Standard & Poor’s (“S&P”) or if unrated, are determined by the Adviser to be of comparable quality; and (ii) derivatives, including swaps and options.

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, industry, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. If the market prices of the securities owned by the Fund fall, the value of your investment will go down. U.S. and non-U.S. governments and central banks have provided significant support to financial markets, including by keeping interest rates at historically low levels. The U.S. Federal Reserve is reducing its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries and other events affecting global markets, such as the United Kingdom’s expected exit from the European Union (or Brexit) are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes 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 or be out of favor for long periods of time. The Adviser may be incorrect when it determines 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.

Short Sales Risk. Short sales involve significant risks. If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss. The Fund may not be able to borrow securities that it needs to take a short position or purchase securities needed to close out a short position at an acceptable price. Also, the lender of a security that the Fund has sold short may terminate the loan at a time when the Fund is unable to borrow the same security from another lender. In that case, the Fund would need to purchase a replacement security at the then current market price or pay the lender the cost of purchasing the security. Because the Fund’s loss on a short sale arises from increases in the value of the security sold short, such loss is theoretically unlimited as there is no limit on any such increases in value. By contrast, the Fund’s loss on a long position arises from decreases in the value of the security and is limited by the fact that a security’s value cannot drop below zero. Short positions involve significant transaction costs.

Derivatives Risk. Using swaps, options and other derivatives can increase Fund losses and reduce opportunities for gains when market prices, interest rates or the derivative instruments themselves behave in a way not anticipated by the Fund. Using derivatives may increase the volatility of the Fund’s net asset value and may not provide the result intended. Derivatives may have a leveraging effect on the Fund. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. Changes in a derivative’s value may not correlate well with the referenced asset or metric. The Fund also may have to sell assets at inopportune times to satisfy its obligations. Derivatives may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Fund. The U.S. government is in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulations may make using derivatives more costly, may limit their availability or utility, or otherwise adversely affect their performance, or may disrupt markets.

Borrowing or Leverage Risk. Leverage occurs when the Fund increases its assets available for investment using borrowings, derivatives or other investments, such as ETFs, that have embedded leverage. Since short sales involve borrowing securities and then selling them, the Fund’s short sales will effectively leverage the Fund’s assets. Borrowing and other transactions used for leverage may cause the value of the Fund’s shares to be more volatile than if the Fund did not borrow or engage in such transactions and creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have, potentially resulting in the loss of all assets. Engaging in such transactions may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations or meet segregation requirements. There are also costs associated with engaging in leverage, and these costs would offset and could eliminate the Fund’s net investment income in any given period. The Fund cannot guarantee that its leveraging strategy will be successful.

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 fluctuations could add to 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 costs, as well as taxable income or capital gains.

Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the Adviser and/or their service providers (including, but not limited to, the Fund’s transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions.

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.

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, industry, regulatory, market or economic developments. Different parts of the U.S. market and different markets around the world can react differently to these developments. If the market prices of the securities owned by the Fund fall, the value of your investment will go down. U.S. and non-U.S. governments and central banks have provided significant support to financial markets, including by keeping interest rates at historically low levels. The U.S. Federal Reserve is reducing its market support activities and has begun raising interest rates. Further Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests. Policy and legislative changes in the U.S. and in other countries and other events affecting global markets, such as the United Kingdom’s expected exit from the European Union (or Brexit) are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes 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 or be out of favor for long periods of time. The Adviser may be incorrect when it determines 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.

Short Sales Risk. Short sales involve significant risks. If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss. The Fund may not be able to borrow securities that it needs to take a short position or purchase securities needed to close out a short position at an acceptable price. Also, the lender of a security that the Fund has sold short may terminate the loan at a time when the Fund is unable to borrow the same security from another lender. In that case, the Fund would need to purchase a replacement security at the then current market price or pay the lender the cost of purchasing the security. Because the Fund’s loss on a short sale arises from increases in the value of the security sold short, such loss is theoretically unlimited as there is no limit on any such increases in value. By contrast, the Fund’s loss on a long position arises from decreases in the value of the security and is limited by the fact that a security’s value cannot drop below zero. Short positions involve significant transaction costs.

Derivatives Risk. Using swaps, options and other derivatives can increase Fund losses and reduce opportunities for gains when market prices, interest rates or the derivative instruments themselves behave in a way not anticipated by the Fund. Using derivatives may increase the volatility of the Fund’s net asset value and may not provide the result intended. Derivatives may have a leveraging effect on the Fund. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. Changes in a derivative’s value may not correlate well with the referenced asset or metric. The Fund also may have to sell assets at inopportune times to satisfy its obligations. Derivatives may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Fund. The U.S. government is in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulations may make using derivatives more costly, may limit their availability or utility, or otherwise adversely affect their performance, or may disrupt markets.

Borrowing or Leverage Risk. Leverage occurs when the Fund increases its assets available for investment using borrowings, derivatives or other investments, such as ETFs, that have embedded leverage. Since short sales involve borrowing securities and then selling them, the Fund’s short sales will effectively leverage the Fund’s assets. Borrowing and other transactions used for leverage may cause the value of the Fund’s shares to be more volatile than if the Fund did not borrow or engage in such transactions and creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have, potentially resulting in the loss of all assets. Engaging in such transactions may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations or meet segregation requirements. There are also costs associated with engaging in leverage, and these costs would offset and could eliminate the Fund’s net investment income in any given period. The Fund cannot guarantee that its leveraging strategy will be successful.

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 fluctuations could add to 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 costs, as well as taxable income or capital gains.

Cybersecurity Risk. Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the Adviser and/or their service providers (including, but not limited to, the Fund’s transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares or receiving distributions.

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.
