Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Scharf 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 35.49% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Scharf Fund primarily invests in equity securities that the Adviser believes have significantly more appreciation potential than downside risk over the long term. Equity securities in which the Fund may invest include, but are not limited to, common and preferred stock of companies of all size market capitalizations, rights and warrants. The Fund may invest up to 50% of its total assets in securities of foreign issuers listed on foreign exchanges (excluding depositary receipts), including up to 25% of its total assets in issuers in emerging markets. The Fund may invest without limit in depositary receipts, such as American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”). The Fund may also invest up to 30% of its total assets in non-money market investment companies, including exchange-traded funds (“ETFs”). The Fund may also invest in Rule 144A securities.
In general, the Adviser utilizes five key elements in its equity investment philosophy: low valuation, discount to fair value, investment flexibility, focus and long-term perspective. Through a proprietary screening process, the Adviser seeks to identify investments with low valuations combined with growing earnings, cash flow and/or book value. The Scharf Fund may also invest in “special situations,” which may occur when the securities of a company are affected by circumstances, including, but not limited to, hidden assets (i.e., assets that may be undervalued on a company’s balance sheet or otherwise difficult to value and therefore not properly reflected in the company’s share price), spinoffs, liquidations, reorganizations, recapitalizations, mergers, management changes and technological changes.
In addition, the Scharf Fund may invest up to 30% of its total assets in fixed-income securities. Fixed-income securities in which the Fund may invest include, but are not limited to, those of domestic and foreign governments, government agencies, inflation-protected securities, asset-backed securities, exchange-traded notes (“ETNs”), money market instruments, convertible securities, bank debt, limited partnerships, municipalities and companies across a wide range of industries, market capitalizations and maturities and may include those that are rated below investment grade (i.e., “junk bonds”). The types of asset-backed securities in which the Fund may invest include mortgage-backed securities.
As part of its research process, the Adviser may consider how environmental, social and governance (“ESG”) issues affect a company’s long-term outlook, in terms of opportunities and/or risks for the business and whether such ESG factors have the potential to influence future stock performance, but such factors are not determinative (i.e. they would not lead the Adviser to buy or sell a security without consideration of other factors in the investment process).

The Scharf Fund may invest up to 100% of its net assets in cash, cash equivalents, and high-quality, short-term debt securities, money market mutual funds and money market instruments due to a lack of suitable investment opportunities or for temporary defensive purposes.
When selling securities, the Adviser considers the same factors it uses in evaluating a security for purchase and generally sells securities that it believes no longer have sufficient upside potential.

Risk [Text Block] rr_RiskTextBlock The Fund cannot guarantee that it will achieve its investment objectives.
Scharf Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including: inflation (or expectations for inflation); interest rates; global demand for particular products or resources; natural disasters or events; pandemic diseases; terrorism; regulatory events; and government controls. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors, which has resulted in disruptions to business operations and supply chains, stress on the global healthcare system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so.
Scharf Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Securities Risk. The value of the Fund’s shares will go up or down based on the movement of the overall stock market and the value of the individual securities held by the Fund, both of which can sometimes be volatile.
Scharf Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Scharf Fund is an actively managed portfolio. The Adviser’s management practices and investment strategies might not produce the desired results. The Adviser may be incorrect in its assessment of a stock’s appreciation potential.
Scharf Fund | Foreign And Emerging Market Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign and Emerging Market Securities Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.
Scharf Fund | Depositary Receipt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Depositary Receipt Risk. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments.
Scharf Fund | Foreign Currency Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Currency Risk. Currency movements may negatively impact value even when there is no change in value of the security in the issuer’s home country. Currency management strategies may substantially change the Scharf Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the Adviser expects.
Scharf Fund | Large-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Large-Sized Company Risk. Larger, more established companies may be unable to respond quickly to new competitive challenges like changes in consumer tastes or innovative smaller competitors. In addition, large-cap companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.
Scharf Fund | Small- And Medium-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small- and Medium-Sized Company Risk. Small- and medium-sized companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of small- and medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general and small-sized companies in particular, are generally less liquid than the equity securities of larger companies.
Scharf Fund | Investment Style Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Investment Style Risk. The Adviser follows an investing style that favors relatively low valuations. At times when this style is out of favor, the Scharf Fund may underperform funds that follow different investing styles.
Scharf Fund | Investment Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Investment Company Risk. When the Scharf Fund invests in an ETF or mutual fund, it will bear additional expenses based on its pro rata share of the ETF’s or mutual fund’s operating expenses, including the potential duplication of management fees. The risk of owning an ETF or mutual fund generally reflects the risks of owning the underlying securities the ETF or mutual fund holds. The Fund also will incur brokerage costs when it purchases ETFs.
Scharf Fund | Fixed-Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Fixed-Income Securities Risk. The following risks are associated with the Scharf Fund’s investment in fixed-income securities.
◦Prepayment and Extension Risk. The risk that the securities may be paid off earlier (prepayment) or later (extension) than expected. Either situation could cause securities to pay lower-than-market rates of interest, which could hurt the Scharf Fund’s yield or share price.
◦Interest Rate Risk. The Fund’s investments in fixed income securities will change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value.
◦Credit Risk. Credit risk is the risk of loss on an investment due to the deterioration of an issuer’s financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer’s securities and may lead to the issuer’s inability to honor its contractual obligations including making timely payment of interest and principal.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Prepayment and Extension Risk. The risk that the securities may be paid off earlier (prepayment) or later (extension) than expected.

Scharf Fund | Fixed-Income Securities Risk, Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock nterest Rate Risk. The Fund’s investments in fixed income securities will change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value.
Scharf Fund | Fixed-Income Securities Risk, Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Credit Risk. Credit risk is the risk of loss on an investment due to the deterioration of an issuer’s financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer’s securities and may lead to the issuer’s inability to honor its contractual obligations including making timely payment of interest and principal.
Scharf Fund | High-Yield Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock High-Yield Securities Risk. Fixed-income securities that are rated below investment grade (i.e., “junk bonds”) are subject to additional risk factors due to the speculative nature of these securities, such as increased possibility of default liquidation of the security, and changes in value based on public perception of the issuer.
Scharf Fund | Municipal Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Municipal Securities Risk. Municipal securities rely on the creditworthiness or revenue production of their issuers or auxiliary credit enhancement features. Municipal securities may be difficult to obtain because of limited supply, which may increase the cost of such securities and effectively reduce a portfolio’s yield. Typically, less information is available about a municipal issuer than is available for other types of securities issuers.
Scharf Fund | Asset-Backed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Asset-Backed Securities Risk.  Asset-backed securities are subject to certain risks including prepayment and call risks. When an obligation is prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid.
Scharf Fund | Mortgage-Backed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Mortgage-Backed Securities Risk. In addition to the general risks associated with fixed-income securities as described above, the structure of certain mortgage-backed securities may make their reaction to interest rates and other factors difficult to predict, which may cause their prices to be more volatile than other fixed-income securities.
Scharf Fund | Exchange-Traded Note Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Exchange-Traded Note Risk.  The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying securities’ markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced index.  In addition, the notes issued by ETNs and held by the Scharf Fund are unsecured debt of the issuer.
Scharf Fund | Bank Debt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Bank Debt Risk.  The Scharf Fund’s investments in secured and unsecured assignments of bank debt may create substantial risk. In making investments in such debt, which are loans made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest.
Scharf Fund | Inflation Protected Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Inflation Protected Securities Risk.  The value of inflation protected securities generally will fluctuate in response to changes in “real” interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates reduced by the expected impact of inflation. In addition, interest payments on inflation-indexed securities will generally vary up or down along with the rate of inflation.
Scharf Fund | Convertible Bond Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Convertible Bond Risk.  Convertible bonds are hybrid securities that have characteristics of both bonds and common stocks and are therefore subject to both debt security risks and equity risk.  Convertible bonds are subject to equity risk especially when their conversion value is greater than the interest and principal value of the bond. The prices of equity securities may rise or fall because of economic or political changes and may decline over short or extended periods of time.
Scharf Fund | Rule 144A Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Rule 144A Securities Risk. The market for Rule 144A securities typically is less active than the market for publicly-traded securities. Rule 144A securities carry the risk that the liquidity of these securities may become impaired, making it more difficult for the Scharf Fund to sell these securities.
Scharf Fund | Special Situations Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Special Situations Risk. There is a risk that the special situation (i.e., spin-off, liquidation, merger, etc.) might not occur, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Scharf Fund. In addition, investments in special situation companies may be illiquid and difficult to value, which will require the Fund to employ fair value procedures to value its holdings in such investments.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Multi-Asset Fund invests in a mix of equity securities and fixed-income securities. Under normal market conditions, the Fund allocates between 50% and 75% of its total assets to equity securities. Equity securities in which the Fund may invest include, but are not limited to, common and preferred stock of companies of all size market capitalizations, rights and warrants. The Fund may invest up to 50% of its total assets in securities of foreign issuers listed foreign exchanges (excluding depositary receipts), including up to 25% of its total assets in issuers in emerging markets. The Fund may invest without limit in depositary receipts, such as American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”). The Fund may also invest up to 30% of its total assets in non-money market investment companies, including exchange-traded funds (“ETFs”). The Fund may also invest up to 20% of its total assets in Rule 144A securities.
Under normal market conditions, the Multi-Asset Fund allocates between 25% and 50% of its total assets to fixed-income securities. Fixed-income securities in which the Fund may invest include, but are not limited to, those of domestic and foreign governments, government agencies, foreign corporate bonds, inflation-protected securities, asset-backed securities, exchange-traded notes (“ETNs”), money-market instruments, convertible securities, bank debt, limited partnerships, municipalities and companies across a wide range of industries, market capitalizations and maturities, and may include, with respect to up to 30% of the Fund’s total assets, those that are rated below investment grade (i.e., “junk bonds”). The types of asset-backed securities in which the Fund may invest include mortgage-backed securities.
In general, the Adviser utilizes five key elements in its equity investment philosophy: low valuation, discount to fair value, investment flexibility, focus and long-term perspective. Through a proprietary screening process, the Adviser seeks to identify equity securities with low valuations combined with growing earnings, cash flow and/or book value. The Multi-Asset Fund may also invest in “special situations,” which may occur when the securities of a company are affected by circumstances, including, but not limited to, hidden assets (i.e., assets that may be undervalued on a company’s balance sheet or otherwise difficult to value and therefore not properly reflected in the company’s share price), spinoffs, liquidations, reorganizations, recapitalizations, mergers, management changes and technological changes. The Adviser seeks to identify fixed-income investments with favorable risk-reward characteristics. In screening for suitable investments, the Adviser considers many factors, including yield-to-maturity, credit quality, liquidity, call risk, duration risk, and capital appreciation potential.
As part of its research process, the Adviser may consider how environmental, social and governance (“ESG”) issues affect a company’s long-term outlook, in terms of opportunities and/or risks for the business and whether such ESG factors have the potential to influence future stock performance, but such factors are not determinative (i.e. they would not lead the Adviser to buy or sell a security without consideration of other factors in the investment process).
The Multi-Asset Fund may invest up to 100% of its net assets in cash, cash equivalents, and high-quality, short-term debt securities, money market mutual funds and money market instruments due to a lack of suitable investment opportunities or for temporary defensive purposes.
When selling securities, the Adviser considers the same factors it uses in evaluating a security for purchase and generally sells securities that it believes no longer have sufficient upside potential.

Scharf Multi-Asset Opportunity Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including: inflation (or expectations for inflation); interest rates; global demand for particular products or resources; natural disasters or events; pandemic diseases; terrorism; regulatory events; and government controls. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors, which has resulted in disruptions to business operations and supply chains, stress on the global healthcare system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so.
Scharf Multi-Asset Opportunity Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Securities Risk. The value of the Fund’s shares will go up or down based on the movement of the overall stock market and the value of the individual securities held by the Fund, both of which can sometimes be volatile.
Scharf Multi-Asset Opportunity Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Multi-Asset Fund is an actively managed portfolio. The Adviser’s management practices and investment strategies might not produce the desired results. The Adviser may be incorrect in its assessment of a stock’s appreciation potential.
Scharf Multi-Asset Opportunity Fund | Foreign And Emerging Market Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign and Emerging Market Securities Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.
Scharf Multi-Asset Opportunity Fund | Depositary Receipt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Depositary Receipt Risk.  Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments.
Scharf Multi-Asset Opportunity Fund | Foreign Currency Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Currency Risk. Currency movements may negatively impact value even when there is no change in value of the security in the issuer’s home country.  Currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Multi-Asset Fund if currencies do not perform as the Adviser expects.
Scharf Multi-Asset Opportunity Fund | Large-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Large-Sized Company Risk. Larger, more established companies may be unable to respond quickly to new competitive challenges like changes in consumer tastes or innovative smaller competitors. In addition, large-cap companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.
Scharf Multi-Asset Opportunity Fund | Small- And Medium-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small- and Medium-Sized Company Risk. Small- and medium-sized companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of small- and medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general and small-sized companies in particular, are generally less liquid than the equity securities of larger companies.
Scharf Multi-Asset Opportunity Fund | Investment Style Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Investment Style Risk. The Adviser follows an investing style that favors relatively low valuations.  At times when this style is out of favor, the Multi-Asset Fund may underperform funds that follow different investing styles.
Scharf Multi-Asset Opportunity Fund | Investment Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Investment Company Risk. When the Multi-Asset Fund invests in an ETF or mutual fund, it will bear additional expenses based on its pro rata share of the ETF’s or mutual fund’s operating expenses, including the potential duplication of management fees. The risk of owning an ETF or mutual fund generally reflects the risks of owning the underlying securities the ETF or mutual fund holds. The Fund also will incur brokerage costs when it purchases ETFs.
Scharf Multi-Asset Opportunity Fund | Fixed-Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Fixed-Income Securities Risk. The following risks are associated with the Multi-Asset Fund’s investment in fixed-income securities.
◦Prepayment and Extension Risk. The risk that the securities may be paid off earlier (prepayment) or later (extension) than expected. Either situation could cause securities to pay lower-than-market rates of interest, which could hurt the Multi-Asset Fund’s yield or share price.
◦Interest Rate Risk. The Fund’s investments in fixed income securities will change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value.
◦Credit Risk. Credit risk is the risk of loss on an investment due to the deterioration of an issuer’s financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer’s securities and may lead to the issuer’s inability to honor its contractual obligations including making timely payment of interest and principal.

Such a deterioration of financial health may result in a reduction of the credit rating of the issuer’s securities and may lead to the issuer’s inability to honor its contractual obligations including making timely payment of interest and principal.
Scharf Multi-Asset Opportunity Fund | High-Yield Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock High-Yield Securities Risk. Fixed-income securities that are rated below investment grade (i.e., “junk bonds”) are subject to additional risk factors due to the speculative nature of these securities, such as increased possibility of default liquidation of the security, and changes in value based on public perception of the issuer.
Scharf Multi-Asset Opportunity Fund | Municipal Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Municipal Securities Risk. Municipal securities rely on the creditworthiness or revenue production of their issuers or auxiliary credit enhancement features. Municipal securities may be difficult to obtain because of limited supply, which may increase the cost of such securities and effectively reduce a portfolio’s yield. Typically, less information is available about a municipal issuer than is available for other types of securities issuers.
Scharf Multi-Asset Opportunity Fund | Asset-Backed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Asset-Backed Securities Risk.  Asset-backed securities are subject to certain risks including prepayment and call risks. When an obligation is prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid.
Scharf Multi-Asset Opportunity Fund | Mortgage-Backed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Mortgage-Backed Securities Risk. In addition to the general risks associated with fixed-income securities as described above, the structure of certain mortgage-backed securities may make their reaction to interest rates and other factors difficult to predict, which may cause their prices to be more volatile than other fixed-income securities.
Scharf Multi-Asset Opportunity Fund | Exchange-Traded Note Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Exchange-Traded Note Risk.  The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying securities’ markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced index.  In addition, the notes issued by ETNs and held by a fund are unsecured debt of the issuer.
Scharf Multi-Asset Opportunity Fund | Bank Debt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Bank Debt Risk.  The Multi-Asset Fund’s investments in secured and unsecured assignments of bank debt may create substantial risk.  In making investments in such debt, which are loans made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest.
Scharf Multi-Asset Opportunity Fund | Inflation Protected Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Inflation Protected Securities Risk. The value of inflation protected securities generally will fluctuate in response to changes in “real” interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates reduced by the expected impact of inflation. In addition, interest payments on inflation-indexed securities will generally vary up or down along with the rate of inflation.
Scharf Multi-Asset Opportunity Fund | Convertible Bond Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Convertible Bond Risk. Convertible bonds are hybrid securities that have characteristics of both bonds and common stocks and are therefore subject to both debt security risks and equity risk.  Convertible bonds are subject to equity risk especially when their conversion value is greater than the interest and principal value of the bond.  The prices of equity securities may rise or fall because of economic or political changes and may decline over short or extended periods of time.
Scharf Multi-Asset Opportunity Fund | Rule 144A Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Rule 144A Securities Risk. The market for Rule 144A securities typically is less active than the market for publicly-traded securities. Rule 144A securities carry the risk that the liquidity of these securities may become impaired, making it more difficult for the Multi-Asset Fund to sell these securities.
Scharf Multi-Asset Opportunity Fund | Special Situations Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Special Situations Risk. There is a risk that the special situation (i.e., spin-off, liquidation, merger, etc.) might not occur, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Multi-Asset Fund. In addition, investments in special situation companies may be illiquid and difficult to value, which will require the Fund to employ fair value procedures to value its holdings in such investments.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Global Opportunity Fund primarily invests in U.S. and non-U.S. equity securities that the Adviser believes have significantly more appreciation potential than downside risk over the long term. Equity securities in which the Fund may invest include, but are not limited to, common and preferred stock of companies of all size market capitalizations, rights and warrants. Under normal circumstances, the Fund will invest at least 40% of its total assets in non-U.S. securities. During unusual market conditions, the Fund will invest at least 30% of its total assets in non-U.S. securities. Such foreign securities may be listed on foreign exchanges as well as in the form of depositary receipts, such as American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”). There are no geographic limits on the Fund’s investments, and the Fund may invest in securities of companies located both in the U.S. and abroad and in developed or emerging markets. However, the Fund will invest primarily in the securities of companies located in at least four different countries. The Fund may also invest up to 30% of its total assets in non-money market investment companies, including mutual funds and exchange-traded funds (“ETFs”). The Fund may also invest in Rule 144A securities. Under normal market conditions, the Fund will typically invest in less than 50 securities.
In general, the Adviser utilizes five key elements in its equity investment philosophy: low valuation, discount to fair value, investment flexibility, focus and long-term perspective. Through a proprietary screening process, the Adviser seeks to identify investments with low valuations combined with growing earnings, cash flow and/or book value. The Global Opportunity Fund may also invest in “special situations,” which may occur when the securities of a company are affected by circumstances, including, but not limited to, hidden assets (i.e., assets that may be undervalued on a company’s balance sheet or otherwise difficult to value and therefore not properly reflected in the company’s share price), spin-offs, liquidations, reorganizations, recapitalizations, mergers, management changes and technological changes.
In addition, the Global Opportunity Fund may invest up to 30% of its total assets in fixed-income securities. Fixed-income securities in which the Fund may invest include, but are not limited to, those of domestic and foreign governments, government agencies, inflation-protected securities, asset-backed securities, exchange-traded notes (“ETNs”), money market instruments, convertible securities, bank debt, limited partnerships, municipalities and companies across a wide range of industries and market capitalizations and may be of any maturity and include those that are rated below investment grade (i.e., “junk bonds”). The types of asset-backed securities in which the Fund may invest include mortgage-backed securities.
As part of its research process, the Adviser may consider how environmental, social and governance (“ESG”) issues affect a company’s long-term outlook, in terms of opportunities and/or risks for the business and whether such ESG factors have the potential to influence future stock performance, but such factors are not determinative (i.e., they would not lead the Adviser to buy or sell a security without consideration of other factors in the investment process).
The Global Opportunity Fund may invest up to 100% of its net assets in cash, cash equivalents, and high-quality, short-term debt securities, money market mutual funds and money market instruments due to a lack of suitable investment opportunities or for temporary defensive purposes.
When selling securities, the Adviser considers the same factors it uses in evaluating a security for purchase and generally sells securities that it believes no longer have sufficient upside potential.

Scharf Global Opportunity Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including: inflation (or expectations for inflation); interest rates; global demand for particular products or resources; natural disasters or events; pandemic diseases; terrorism; regulatory events; and government controls. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors, which has resulted in disruptions to business operations and supply chains, stress on the global healthcare system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so.
Scharf Global Opportunity Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Securities Risk. The value of the Fund’s shares will go up or down based on the movement of the overall stock market and the value of the individual securities held by the Fund, both of which can sometimes be volatile.
Scharf Global Opportunity Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Global Opportunity Fund is an actively managed portfolio. The Adviser’s management practices and investment strategies might not produce the desired results. The Adviser may be incorrect in its assessment of a stock’s appreciation potential.
Scharf Global Opportunity Fund | Foreign And Emerging Market Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign and Emerging Market Securities Risk. Investments in foreign currencies and foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, sanctions or other measures by the United States or other governments, liquidity risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, and less stringent investor protection and disclosure standards of foreign markets. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.
Scharf Global Opportunity Fund | Depositary Receipt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Depositary Receipt Risk. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments.
Scharf Global Opportunity Fund | Foreign Currency Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Currency Risk. Currency movements may negatively impact value even when there is no change in value of the security in the issuer’s home country. Currency management strategies may substantially change the Global Opportunity Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the Adviser expects.
Scharf Global Opportunity Fund | Large-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Large-Sized Company Risk. Larger, more established companies may be unable to respond quickly to new competitive challenges like changes in consumer tastes or innovative smaller competitors. In addition, large-cap companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.
Scharf Global Opportunity Fund | Small- And Medium-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small- and Medium-Sized Company Risk. Small- and medium-sized companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of small- and medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general and small-sized companies in particular, are generally less liquid than the equity securities of larger companies.
Scharf Global Opportunity Fund | Investment Style Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Investment Style Risk. The Adviser follows an investing style that favors relatively low valuations.  At times when this style is out of favor, the Global Opportunity Fund may underperform funds that follow different investing styles.
Scharf Global Opportunity Fund | Investment Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Investment Company Risk. When the Global Opportunity Fund invests in an ETF or mutual fund, it will bear additional expenses based on its pro rata share of the ETF’s or mutual fund’s operating expenses, including the potential duplication of management fees. The risk of owning an ETF or mutual fund generally reflects the risks of owning the underlying securities the ETF or mutual fund holds. The Fund also will incur brokerage costs when it purchases ETFs.
Scharf Global Opportunity Fund | Fixed-Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Fixed-Income Securities Risk. The following risks are associated with the Global Opportunity Fund’s investment in fixed-income securities.
◦Prepayment and Extension Risk. The risk that the securities may be paid off earlier (prepayment) or later (extension) than expected. Either situation could cause securities to pay lower-than-market rates of interest, which could hurt the Global Opportunity Fund’s yield or share price.
◦Interest Rate Risk. The Fund’s investments in fixed income securities will change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value.
◦Credit Risk. Credit risk is the risk of loss on an investment due to the deterioration of an issuer’s financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer’s securities and may lead to the issuer’s inability to honor its contractual obligations including making timely payment of interest and principal.

Scharf Global Opportunity Fund | High-Yield Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock High-Yield Securities Risk. Fixed-income securities that are rated below investment grade (i.e., “junk bonds”) are subject to additional risk factors due to the speculative nature of these securities, such as increased possibility of default liquidation of the security, and changes in value based on public perception of the issuer.
Scharf Global Opportunity Fund | Municipal Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Municipal Securities Risk. Municipal securities rely on the creditworthiness or revenue production of their issuers or auxiliary credit enhancement features. Municipal securities may be difficult to obtain because of limited supply, which may increase the cost of such securities and effectively reduce a portfolio’s yield. Typically, less information is available about a municipal issuer than is available for other types of securities issuers.
Scharf Global Opportunity Fund | Asset-Backed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Asset-Backed Securities Risk. Asset-backed securities are subject to certain risks including prepayment and call risks. When an obligation is prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid.
Scharf Global Opportunity Fund | Mortgage-Backed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Mortgage-Backed Securities Risk. In addition to the general risks associated with fixed-income securities as described above, the structure of certain mortgage-backed securities may make their reaction to interest rates and other factors difficult to predict, which may cause their prices to be more volatile than other fixed-income securities.
Scharf Global Opportunity Fund | Exchange-Traded Note Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Exchange-Traded Note Risk. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying securities’ markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced index.  In addition, the notes issued by ETNs and held by the Global Opportunity Fund are unsecured debt of the issuer.
Scharf Global Opportunity Fund | Bank Debt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Bank Debt Risk. The Global Opportunity Fund’s investments in secured and unsecured assignments of bank debt may create substantial risk.  In making investments in such debt, which are loans made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest.
Scharf Global Opportunity Fund | Inflation Protected Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Inflation Protected Securities Risk. The value of inflation protected securities generally will fluctuate in response to changes in “real” interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates reduced by the expected impact of inflation. In addition, interest payments on inflation-indexed securities will generally vary up or down along with the rate of inflation.
Scharf Global Opportunity Fund | Convertible Bond Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Convertible Bond Risk. Convertible bonds are hybrid securities that have characteristics of both bonds and common stocks and are therefore subject to both debt security risks and equity risk. Convertible bonds are subject to equity risk especially when their conversion value is greater than the interest and principal value of the bond. The prices of equity securities may rise or fall because of economic or political changes and may decline over short or extended periods of time.
Scharf Global Opportunity Fund | Rule 144A Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Rule 144A Securities Risk. The market for Rule 144A securities typically is less active than the market for publicly-traded securities. Rule 144A securities carry the risk that the liquidity of these securities may become impaired, making it more difficult for the Global Opportunity Fund to sell these securities.
Scharf Global Opportunity Fund | Special Situations Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Special Situations Risk. There is a risk that the special situation (i.e., spin-off, liquidation, merger, etc.) might not occur, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Global Opportunity Fund. In addition, investments in special situation companies may be illiquid and difficult to value, which will require the Fund to employ fair value procedures to value its holdings in such investments.
