If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

In general, for a period of up to 36 months from the time of any waiver, reimbursement, or payment pursuant to the Fund's contractual expense limitation, the Investment Manager may recover from the Fund fees waived and expenses paid to the extent that such repayment would not cause the Fund's Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursements to exceed the contractual expense limitation amount. Under such arrangement, if the maximum amount of shareholder servicing fees were charged to the classes under the current applicable plans, the total annual fund operating expenses (excluding the other items noted in the parenthetical above) of the Managers Class and Institutional Class would be 1.40% and 1.15%, respectively, of the average daily net assets of such classes. The contractual expense limitation may only be terminated upon termination of the Fund's investment advisory agreement with the Investment Manager or by mutual agreement between the Investment Manager and the Fund's Board of Trustees.27Annual Fund Operating Expenses Managers Special Equity FundUnKnownUnKnownUnKnownUnKnownfalsetrueColumnperiodPeriod*Columndei_LegalEntityAxisAxis*Columnrr_ProspectusShareClassAxisAxis*ColumnunitUnit*RowprimaryElement*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to OperatingExpensesData.No authoritative reference available.falsefalseAnnual Fund Operating Expenses [Table]10false0rr_ExpenseExampleHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00EXPENSE EXAMPLEfalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringHeading for Expense Example.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 4 -Subsection instructions falsefalseExpense Example, Heading11false0rr_ExpenseExampleNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<pre>This Example will help you compare the cost of investing in the Fund to the cost of investing in other mutual funds.

Although the Fund focuses its investments in securities of small- and medium-capitalization companies pursuant to its investment objective, the Fund has historically invested substantially all of its assets in the securities of U.S. small-capitalization companies. Typically, the Fund invests in companies with capitalizations that are within the range of capitalizations of companies in the Russell 2000&#xAE; Growth Index. As of December 31, 2010, the range of market capitalizations for the Russell 2000&#xAE; Growth Index was $19.9 million to $5.2 billion. The Fund may purchase securities, or retain securities that it already has purchased, even if the securities are outside the Fund's typical capitalization range. The Fund's assets are currently allocated among four Subadvisors, each of which acts independently of the others and uses its own methodology to select portfolio investments. Specifically: &#x2022; The Subadvisors utilize a growth approach to investing whereby three of the four Subadvisors seek to identify companies that are exhibiting rapid growth in their businesses and the fourth seeks to identify companies that possess better than average long-term growth rates combined with several other fundamental characteristics. &#x2022; Three of the four Subadvisors examine the underlying businesses, financial statements, competitive environment and company management in order to assess the future profitability of each company. &#x2022; One of the four Subadvisors utilizes a quantitative investment approach to evaluate each company based on fundamental characteristics such as earnings estimate momentum, long-term growth rate, tangible book to price ratio, earnings to price ratio, and use of external financing. &#x2022; A Subadvisor may sell a security if it believes that the future profitability of a company does not support the current stock price. With the combination of the above strategies, the Fund expects to generate returns from capital appreciation due to earnings growth along with improvements in the valuations of the securities such as, among other things, increases in the price to earnings ratios.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Below are some of the risks of investing in the Fund. Growth Stock Risk-growth stocks may be more sensitive to market movements because their prices tend to reflect future investor expectations rather than just current profits. Liquidity Risk-particular investments, such as illiquid securities, may not be able to be sold at the price the Fund would like or the Fund may have to sell them at a loss. Market Risk-market prices of securities held by the Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political, or market conditions.

A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table, Narrative26false0rr_AverageAnnualReturnCaptionrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsetruefalse00Average Annual Total Returns as of 12/31/10 falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringThis item represents Average Anuual Total Returns.
