This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.


ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)
Management Fees			0.70%
Other Expenses			0.31%
Acquired Fund Fees and Expenses			0.01%
Total Annual Fund Operating Expenses(1)			1.02%
Less: Fee Waiver(2)			-0.01%
Total Annual Fund Operating Expenses After Fee Waiver			1.01%

(1)Total Annual Fund Operating Expenses do not correlate to the “Ratio of Expenses to Average Net Assets Before Fee Waivers” found in the Financial Highlights of the statutory prospectus, which reflects the Fund’s operating expenses and does not include expenses attributed to acquired fund fees and expenses (“AFFE”).

(2)Capital Advisors, Inc. (the “Advisor”) has contractually agreed to waive a portion or all of its management fees and pay Fund expenses to ensure that Total Annual Fund Operating Expenses (excluding AFFE, taxes, interest, extraordinary expenses, and any other class-specific expenses) do not exceed 1.00% of the Fund’s average daily net assets (the “Expense Cap”). The Expense Cap will remain in effect through at least April 28, 2025, and may only be terminated by the Board of Trustees (the “Board”).

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 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 remain the same (taking into account the Expense Cap only in the first year). Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

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 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 11.82% of the average value of its portfolio.

The Fund invests primarily in common stocks of domestic (U.S.) companies. The Fund may also invest in securities of foreign companies that are publicly traded in the U.S., including in American Depositary Receipts (“ADRs”). Under normal conditions, the Fund invests at least 65% of its total assets in common stocks of companies that the Advisor believes have the potential for long-term growth of capital. The Advisor uses the growth style of investing. Growth stocks are equity securities of companies that have or are expected to have above-average earnings growth.

The Fund buys and sells stocks based on the Advisor’s research, and focuses on characteristics that the Advisor believes allow a company to grow at an above-average rate for an extended period of time, including: dominant position within its industry; sustainable competitive advantage; shareholder oriented management philosophy; strong brand or franchise value; operating within a definable growing market; and strong research and development.

The Fund cannot guarantee that it will achieve its investment objective. There is the risk that you could lose all or a portion of your investment in the Fund. The following risks are considered principal and could adversely affect the value of your investment in the Fund.

•General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including: inflation (or expectations for inflation); interest rates; global demand for particular products or resources; natural disasters or events; pandemic diseases; terrorism; regulatory events; and government controls. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors, which has resulted in disruptions to business operations and supply chains, stress on the global healthcare system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty.

Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so.

•Equity Securities Risk – The value of the Fund’s shares will go up or down based on the movement of the overall stock market and the value of the individual securities held by the Fund, both of which can sometimes be volatile.

•Depositary Receipt Risk – The risks of depository receipts include many risks associated with investing directly in foreign securities, such as individual country risk and liquidity risk. Unsponsored ADRs, which are issued by a depositary bank without the participation or consent of the issuer, involve additional risks because U.S. reporting requirements do not apply, and the issuing bank will recover shareholder distribution costs from movement of share prices and payment of dividends.

•Non-U.S. Investment Risk – Foreign securities can be more volatile than domestic (U.S.) securities. Securities markets of other countries are generally smaller than U.S. securities markets. Many foreign securities may be less liquid and more volatile than U.S. securities, which could affect the Fund’s investments.
