The Fund pays transaction costs, such as commissions and dealer mark-ups, 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 portfolio turnover rate for the Fund was 32% of the average value of its portfolio.

rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees

Acquired Fund Fees and Expenses are indirect fees and expenses that a Fund incurs from investing in the shares of other mutual funds, including money market funds and exchange traded funds. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table will differ from the "Financial Highlights" section of the Prospectus which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal conditions, Brown Advisory LLC (the “Adviser”) seeks to achieve the Fund’s investment objective by investing at least 80% of the value of its net assets (plus borrowings for investment purposes) in a diversified portfolio of dividend paying common stocks. The Adviser may invest in securities of companies of various market capitalizations but will focus on medium and large capitalization companies. Medium and large market capitalization companies are, according to the Adviser, those companies with market capitalizations of greater than $2 billion at the time of initial investment. Equity securities include domestic and foreign common and preferred stock, convertible debt securities, American Depositary Receipts (“ADRs”), Master Limited Partnerships (“MLPs”), real estate investment trusts (“REITs”) and exchange traded funds (“ETFs”), and the Adviser may also invest in private placements in these types of securities. To the extent the Fund invests in MLPs, its investments will be restricted to holding interests in limited partners of such investments. To the extent the Fund invests in ETFs, it will do so primarily in ETFs that have an investment objective similar to the Fund’s or that otherwise are permitted investments with the Fund’s investment policies described herein. ADRs are equity securities traded on U.S. securities exchanges, which are generally issued by banks or trust companies to evidence ownership of foreign equity securities. The Adviser may also invest in debt-securities, including lower-rated debt-securities (“junk bonds”) and foreign securities including depositary receipts.

As the Adviser seeks to reduce the risk of permanent loss of capital, the Adviser follows an investment strategy referred to as “equity income, emphasizing current income and a conservative stock portfolio. The equity income strategy seeks to generally maintain a portfolio yield that is greater than the S&P 500 Index. Within that context, the balance between current income and prospective growth of dividends is driven by fundamental stock selection.

The Fund may invest up to 25% of its net assets in publicly traded Master Limited Partnerships (“MLPs”). MLPs are businesses organized as limited partnerships that trade their proportionate shares of the partnership (units) on a public exchange. MLPs are required to pay out most or all of their earnings in distributions.

With respect to 20% of its assets, the Fund may invest in (1) investment grade and non-investment grade debt securities ( i.e., junk bonds), or (2) unrated debt securities determined by the Adviser to be of comparable quality.

The Adviser may sell a stock if the stock has reached a price whereby its risk/reward characteristics are not as favorable, the company’s fundamentals have deteriorated so that the original investment thesis for holding the stock no longer holds or if there is a better opportunity has been identified.

In order to respond to adverse market, economic, political, or other conditions, the Fund may assume a temporary defensive position that is inconsistent with its investment objective and principal investment strategy and invest without limit in cash and prime quality cash equivalents such as prime commercial paper and other money market instruments. A defensive position, taken at the wrong time, may have an adverse impact on the Fund’s performance. The Fund may be unable to achieve its investment objective during the employment of a temporary defensive measure.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, there is the risk that you could lose all or a portion of your investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following are the principal risks that could affect the value of your investment:

●

American Depositary Receipts (“ADRs”) Risk. ADRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR holders. Because unsponsored ADR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and voting rights with respect to the deposited securities are not passed through.

●	Convertible Securities Risk. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

●

Debt/Fixed Income Securities Risk. An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio of debt securities. Interest rates in the United States are at, or near, historic lows, which may increase the Fund’s exposure to risks associated with rising interest rates. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund’s manager might wish to sell. Lower rated securities (“junk bonds”) are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline.

●

Equity and General Market Risk . Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The stock market may experience declines or stocks in the Fund’s portfolio may not increase their earnings at the rate anticipated. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities.

●

ETF Risk. ETFs may trade at a discount to the aggregate value of the underlying securities and although expense ratios for ETFs are generally low, frequent trading of ETFs by the Fund can generate brokerage expenses. Shareholders of the Fund will indirectly be subject to the fees and expenses of the individual ETFs in which the Fund invests.

●	Foreign Securities Risk. Foreign securities, including ADRs, are subject to additional risks including international trade, currency, political, regulatory and diplomatic risks.

●	Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

●	Master Limited Partnership Risk. Investing in Master Limited Partnerships (“MLPs”) entails risk related to fluctuations in energy prices, decreases in supply of or demand for energy commodities, unique tax consequences due to the partnership structure and various other risks.

●

Non-Investment Grade (“Junk Bond”) Securities Risk. Securities rated below investment grade, i.e., Ba or BB and lower (“junk bonds”), are subject to greater risks of loss of your money than higher rated securities. Compared with issuers of investment grade fixed-income securities, junk bonds are more likely to encounter financial difficulties and to be materially affected by these difficulties.

●

Private Placement Risk. The Fund may invest in privately issued securities of domestic common and preferred stock, convertible debt securities, ADRs, REITs and ETFs, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, as amended (“1933 Act”). Privately issued securities are restricted securities that are not publicly traded. Delay or difficulty in selling such securities may result in a loss to the Fund.

●

REIT and Real Estate Risk. The value of the Fund’s investments in REITs may change in response to changes in the real estate market such as declines in the value of real estate, lack of available capital or financing opportunities, and increases in property taxes or operating costs. Shareholders of the Fund will indirectly be subject to the fees and expenses of the individual REITs in which the Fund invests.

●

Smaller and Medium Capitalization Company Risk. Securities of smaller and medium-sized companies may be more volatile and more difficult to liquidate during market down turns than securities of larger companies. Additionally the price of smaller companies may decline more in response to selling pressures.

●	Value Company Risk . The stock of value companies can continue to be undervalued for long periods of time and not realize its expected value. The value of the Fund may decrease in response to the activities and financial prospects of an individual company.
