EXAMPLE

Expense Example Narrative [Text Block]

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 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 (including capped expenses for the period described in the footnote to the fee table) remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover [Heading]

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

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. During its most recent fiscal year, the Fund's portfolio turnover rate was 72% of the average value of its portfolio.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGY

Strategy Narrative [Text Block]

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of small capitalization companies. The Adviser defines small capitalization companies as companies with market capitalizations, at the time of acquisition, within the range of market capitalizations of companies constituting the Russell 2000 Index. The securities in which the Fund invests are primarily common stock and real estate investment trusts ("REITs").

The Adviser uses a value investment strategy based on proprietary fundamental research. Value investing involves buying stocks that, in the view of the Adviser, are out of favor or undervalued relative to their peers. The Adviser emphasizes companies with the ability to generate discretionary cash flow after spending what is required to maintain the business at its current level of revenue, and to redeploy such cash flow to enhance value. The Adviser also looks for the following characteristics:

o Stable and predictable business model

o Motivated and competent management

o Unduly depressed valuation

o Catalyst for positive market revaluation

To manage risk, the Adviser seeks to adhere to a strong buy, hold and sell discipline. The Adviser may sell a security if (1) its expected return falls below certain levels due to price appreciation, (2) its market capitalization appreciates above the range of small capitalization securities, (3) there are, in the view of the Adviser, adverse changes in the fundamentals of the issuer, (4) the Adviser believes that the business model of the issuer becomes unpredictable, or (5) the Adviser believes better relative value exists elsewhere.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

EQUITY MARKET RISK -- The risk that stock prices will fall over short or extended periods of time.

MANAGER RISK -- The performance of the Fund is dependent upon the portfolio managers' skill in making appropriate investments. The Adviser's investment strategy may fail to produce the intended result. As a result, the Fund may underperform its benchmark or peers.

REIT RISK -- REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund's investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this Prospectus.

SMALL CAPITALIZATION COMPANIES RISK -- The risk that small capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization stocks may be more volatile than those of larger companies. Small capitalization stocks may be traded over-the-counter or listed on an exchange. The market for small capitalization companies may be less liquid than the market for larger capitalization companies.

VALUE STYLE RISK -- If the Adviser's assessment of market conditions, or a company's value or its prospects for exceeding earnings expectations is inaccurate, the Fund could suffer losses or produce poor performance relative to other funds. In addition, "value stocks" may continue to be undervalued by the market for long periods of time.

[1] Cardinal Capital Management, L.L.C. (the "Adviser") has contractually agreed to reduce its fees and/or reimburse expenses in order to keep Total Annual Fund Operating Expenses (excluding interest, taxes, brokerage commissions, Acquired Fund Fees and Expenses and extraordinary expenses (collectively, "Excluded Expenses")) from exceeding 1.00% of the Fund's Institutional Class shares' average daily net assets until May 31, 2018 (the "Contractual Expense Limit").
