Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover 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 the Total 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 10.6% of the average value of its portfolio.

This Example is intended to help you compare the costs of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of companies with medium-sized market capitalizations (“mid-cap companies”). The Fund defines mid-cap companies as those companies with market capitalizations within the range of companies in the Russell Midcap® Growth Total Return Index at the time of investment. As of May 31, 2019, the market capitalization range of companies in the Russell Midcap® Growth Total Return Index was between $1.3 billion and $48.6 billion.

The Fund seeks to achieve its investment objective by investing primarily in common stocks of mid-cap U.S. companies. Equity securities in which the Fund may invest also include preferred stocks, convertible debt securities, and other investment companies and exchange-traded funds (“ETFs”) that invest in equity securities of mid-cap companies. In addition to U.S. companies, the Fund may invest up to 25% of its net assets in securities of foreign mid-cap companies that are traded in the U.S., including companies located in emerging markets, as well as American Depositary Receipts (“ADRs”).

In selecting investments for the Fund, Bright Rock Capital Management, LLC, the Fund’s investment adviser (the “Adviser”), seeks to identify companies with attractive earnings growth prospects. Investments for the Fund’s portfolio are selected by applying the Adviser’s disciplined, bottom-up fundamental research process, which takes into account a company’s history of earnings stability and growth; proprietary products, processes and/or services; leadership or competitive positions in the market or industry; balance sheet strength; and experience of management teams. The Adviser may sell an investment in the Fund’s portfolio when the investment no longer meets the Adviser’s criteria for investments with strong growth potential or when a more attractive investment opportunity arises.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
Before investing in the Fund, you should carefully consider your own investment goals, the amount of time you are willing to leave your money invested, and the amount of risk you are willing to take. Remember, in addition to possibly not achieving your investment goals, you could lose all or a portion of your investment in the Fund over short or even long periods of time. The principal risks of investing in the Fund are:

•
Management Risk. Investment strategies employed by the Adviser in selecting investments and asset allocations for the Fund may not result in an increase in the value of your investment or in overall performance equal to other similar investment vehicles having similar investment strategies.
•
General Market Risk. Certain securities selected for the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
•
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests.
•
Preferred Stock Risk. Preferred stock is subject to the risk that the dividend on the stock may be changed or omitted by the issuer, and that participation in the growth of an issuer may be limited.
•
Convertible Securities Risk. A convertible security is a fixed-income security (a debt instrument or a preferred stock) which may be converted at a stated price within a specified period of time into a certain quantity of the common stock of the same or a different issuer. The market value of a convertible security performs like that of a regular debt security, that is, if market interest rates rise, the value of the convertible security falls.
•
Growth Stock Risk. The prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks.
•
Mid-Cap Company Risk. Mid-cap companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these mid-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, mid-cap stocks may be more volatile than the stocks of larger companies.
•
Shares of Other Investment Companies Risk. You will indirectly bear fees and expenses charged by the underlying funds in addition to the Fund’s direct fees and expenses. As a result, your cost of investing in the Fund will generally be higher than the cost of investing directly in the underlying fund shares.
•
Exchange-Traded Funds Risk. There are risks related to investing in ETFs that do not apply to investments in conventional mutual funds, including that the market price of an ETF’s shares may trade at a discount to their net asset value (“NAV”) or that an active trading market for an ETF’s shares may not develop or be maintained.
•
Foreign Securities Risk. The risks of investments in securities of foreign companies involve risks not generally associated with investments in the securities of U.S. companies, including risks relating to political, social and economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices, including fluctuations in foreign currencies. Income earned on foreign stocks and securities may be subject to foreign withholding taxes.
•
Emerging Markets Risk. Countries in emerging markets are generally more volatile and can have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that trade a small number of issues.
•
Not a Bank Deposit. Investments by any investors in the Fund are not bank deposits, are not guaranteed by any bank, are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, and are subject to investment risks, including possible loss of the principal invested.
•
Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of companies with large-sized market capitalizations (“large-cap companies”). The Fund defines large-cap companies as those companies with market capitalizations within the range of companies in the Russell 1000® Index at the time of investment. As of May 31, 2019, the market capitalization range of companies in the Russell 1000® Index was between $552.1 million and $947.7 billion.

The Fund seeks to achieve its investment objective by investing primarily in common stocks of large-cap U.S. companies. Equity securities in which the Fund may invest also include preferred stocks, convertible debt securities, and other investment companies and exchange-traded funds (“ETFs”) that invest in equity securities of large-cap companies. In addition to U.S. companies, the Fund may invest up to 25% of its net assets in securities of foreign large-cap companies that are traded in the U.S., including companies located in emerging markets, as well as American Depositary Receipts (“ADRs”).

In selecting investments for the Fund, Bright Rock Capital Management, LLC, the Fund’s investment adviser (the “Adviser”), seeks to identify high quality businesses by applying its disciplined, bottom-up fundamental research process, which takes into account a company’s history of earnings stability and growth; proprietary products, processes and/or services; leadership or competitive positions in the market or industry; balance sheet strength; and experience of management teams. The Fund will invest in both growth and value stocks, and will maintain exposure across a variety of industry sectors. The Adviser utilizes a proprietary quality screening methodology to determine companies that meet the Adviser’s criteria for inclusion in the quality universe. The Adviser may sell an investment in the Fund’s portfolio when the investment no longer meets the Adviser’s criteria for investments in high quality businesses or when a more attractive investment opportunity arises.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
Before investing in the Fund, you should carefully consider your own investment goals, the amount of time you are willing to leave your money invested, and the amount of risk you are willing to take. Remember, in addition to possibly not achieving your investment goals, you could lose all or a portion of your investment in the Fund over short or even long periods of time. The principal risks of investing in the Fund are:

•
Management Risk. Investment strategies employed by the Adviser in selecting investments and asset allocations for the Fund may not result in an increase in the value of your investment or in overall performance equal to other similar investment vehicles having similar investment strategies.
•
General Market Risk. Certain securities selected for the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
•
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests.
•
Preferred Stock Risk. Preferred stock is subject to the risk that the dividend on the stock may be changed or omitted by the issuer, and that participation in the growth of an issuer may be limited.
•
Convertible Securities Risk. A convertible security is a fixed-income security (a debt instrument or a preferred stock) which may be converted at a stated price within a specified period of time into a certain quantity of the common stock of the same or a different issuer. The market value of a convertible security performs like that of a regular debt security, that is, if market interest rates rise, the value of the convertible security falls.
•
Growth Stock Risk. The prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks.
•
Value Stock Risk. Value stocks may perform differently from the market as a whole and may continue to be undervalued by the market for long periods of time.
•
Large-Cap Company Risk. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors. Also, large-cap companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.
•
Shares of Other Investment Companies Risk. You will indirectly bear fees and expenses charged by the underlying funds in addition to the Fund’s direct fees and expenses. As a result, your cost of investing in the Fund will generally be higher than the cost of investing directly in the underlying fund shares.
•
Exchange-Traded Funds Risk. There are risks relating to investing in ETFs that do not apply to investments in conventional mutual funds, including that the market price of an ETF’s shares may trade at a discount to their net asset value (“NAV”) or that an active trading market for an ETF’s shares may not develop or be maintained.
•
Foreign Securities Risk. The risks of investments in securities of foreign companies involve risks not generally associated with investments in the securities of U.S. companies, including risks relating to political, social and economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices, including fluctuations in foreign currencies. Income earned on foreign stocks and securities may be subject to foreign withholding taxes.
•
Emerging Markets Risk. Countries in emerging markets are generally more volatile and can have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that trade a small number of issues.
•
Not a Bank Deposit. Investments by any investors in the Fund are not bank deposits, are not guaranteed by any bank, are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency, and are subject to investment risks, including possible loss of the principal invested.
•
Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Fund Shares” may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an annual tax deduction that benefits the investor.
