FUND INVESTMENT OBJECTIVE

The investment objective of the Perimeter Small Cap Growth Fund (the "Fund") is to seek long-term capital appreciation.

EXPENSES AND FEES

This table describes the fees and expenses that you may pay if you buy and hold I Shares of the Fund.

	I Shares
Shareholder Fees (fees paid directly from your investment)
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)		None
Maximum Deferred Sales Charge (Load)		None
Maximum Sales Charge (Load) Imposed on Reinvested Dividends		None
Redemption Fee (charged on redemptions within 7 days of purchase)		2.00	%
Exchange Fee		None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees		0.90	%
Distribution (12b-1) Fees		None
Other Expenses		0.32	%
Total Annual Fund Operating Expenses		1.22	%
Fee Waiver and/or Expense Reimbursement(1)		(0.12	)%
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement		1.10	%

  (1)  The Adviser has contractually agreed to waive its advisory fee and/or reimburse expenses in order to limit Total Annual Fund Operating Expenses (other than Acquired Fund fees and expenses, brokerage commissions, extraordinary items, interest or taxes) to 1.10% of the Fund's average daily net assets attributable to I Shares through December 31, 2011. If at any time during the first three years the Advisory Agreement is in effect, the Fund's Total Annual Fund Operating Expenses for that year are less than 1.10%, the Adviser may recoup any waived amount from the Fund if such reimbursement does not cause the Fund to exceed existing expense limitations.

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 assumes that you invest $10,000 in the Fund for the time periods indicated and that you sell 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. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be:

1 Year		3 Years		5 Years		10 Years
$	112	$	375	$	659	$	1,467

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund's performance. On February 8, 2010, substantially all of the assets of the Perimeter Small Cap Growth Fund, a portfolio of The Advisors' Inner Circle Fund II (the "Predecessor Fund"), were transferred to the Fund in a tax-free reorganization (the "Reorganization"). As a result of the Reorganization, the performance and accounting history of the Predecessor Fund prior to the date of the Reorganization was assumed by the Fund and the Fund's fiscal year end changed from July 31 to August 31. During the most recent fiscal year ended July 31, 2010 and for the period from August 1, 2010 through August 31, 2010, the Fund's portfolio turnover rate was 97% and 7% (not annualized), respectively, of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its net assets in small-cap equity securities. This investment policy may be changed by the Fund upon 60 days' prior notice to shareholders. The Fund currently defines small-cap equity securities as those of companies with market capitalizations between $50 million and $3 billion at the time of purchase. The Fund's investments will generally consist of U.S. traded securities, which may include American Depositary Receipts ("ADRs"), among other types of securities.

The Fund's investment philosophy is based on the premise that a portfolio of small cap stocks with positive earnings trends, reasonable valuation, and strong fundamentals will provide superior returns over time. The Adviser selects companies with strong current earnings growth, improving profitability, strong balance sheets, and strong current and projected business fundamentals which are priced at reasonable valuations. The Adviser believes in executing a very disciplined and objective investment process and in controlling risk through a broadly diversified portfolio. Because companies tend to shift in relative attractiveness, the Fund may buy and sell securities frequently, which may result in higher transaction costs, additional capital gains tax liabilities and may adversely impact performance. In addition, in order to implement its investment strategy, the Adviser may buy or sell, to a limited extent, derivative instruments (such as futures, options, and swaps) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as market risk. The Adviser will not necessarily sell a security that has appreciated or depreciated outside the stated market capitalization range defined above.

PRINCIPAL INVESTMENT RISKS

As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund.

The Fund is also subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. The small-capitalization companies that the Fund invests in may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these small-cap companies may have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small-cap stocks

may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange.

Because the Fund may invest in ADRs, it is subject to some of the same risks as direct investments in foreign companies. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States.
