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 the 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. For the fiscal year ended March 31, 2024, the portfolio turnover rate of the Fund was 44% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or sell 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. This Example does not include the brokerage commissions that investors may pay on their purchases and sales of Fund shares.

Strategy Narrative [Text Block]

The Fund is an actively managed exchange-traded fund (“ETF”) that invests primarily in equity securities listed on a U.S. exchange based on the results of a proprietary, quantitative research system called “Fundametrics®” developed by CornerCap Investment Counsel, Inc. (the “Adviser”). Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in the securities of large-capitalization companies. The Adviser defines large-capitalization companies to be those companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was between $3,085 billion and $189 million as of May 31, 2024 and is expected to change frequently.

The Adviser uses Fundametrics® to select stocks for the Fund. Fundametrics® evaluates all stocks in the Fund’s investable universe and groups companies with similar characteristics into custom peer groups. Each peer group is evaluated with respect to over 120 fundamental factors across all major styles (value, growth, growth at a reasonable price, price momentum, quality, and risk) to find the optimized risk adjusted mix. Overall, valuation maintains the highest weight and greatest importance, but each peer group can have an independent style representation.

Buy and sell decisions are determined by the optimized subset of factors contained within the Fundametrics® Alpha Composite (“Alpha Composite”) and the Fundametrics® Financial Warnings Overlay (“Financial Warnings Overlay”). The Alpha Composite is a combination of factors designed to identify alpha stocks, which are stocks considered to have the potential for excess returns. The Adviser selects securities from among approximately 500 issuers ranked according to fundamental factors using the Adviser’s Alpha Composite. Among other fundamental factors, the Alpha Composite model emphasizes the following three key criteria when choosing equity securities with the potential for long-term capital appreciation:

•relative valuation;

•earnings growth rates; and

•cash flow measurements.

The top 30% ranking stocks from the Alpha Composite make up the investable universe of stocks that may be purchased by the Fund. The Financial Warnings Overlay is then applied to the Fund’s investable universe of stocks using a separate set of risk factors designed to identify stocks with risk levels that the Adviser believes will lead to underperformance. The Financial Warnings Overlay is designed to avoid high risk stocks that otherwise rank attractively in the Alpha Composite. The Financial Warnings Overlay reviews financial statement metrics including earnings quality, capital structure and profitability, sentiment indicators and relative metrics across the universe. The Fund buys stocks that score within the top 30% with respect to the Alpha Composite and pass the Financial Warnings Overlay and, as a final analysis, improve portfolio diversification. The Fund sells stocks that fail to fall within the top 30% with respect to the Alpha Composite or are flagged by the Financial Warnings Overlay as presenting unreasonable risk.

The Fund may lend its portfolio securities to brokers, dealers, and other financial organizations. These loans, if and when made, may not exceed 33 1/3% of the total asset value of the Fund (including the loan collateral). By lending its securities, the Fund may increase its income by receiving payments from the borrower.

Performance Table Explanation after Tax Higher

rr_PerformanceTableExplanationAfterTaxHigher

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