(1)The “Total Annual Fund Operating Expenses” and “Total Annual Fund Operating Expenses After Fee Waiver/Expense Reimbursement” for Service Class shares do not correlate to the “Ratio of expenses to average net assets” figures in the Financial Highlights section of this Prospectus because Service Class shares accrued shareholder servicing fees in the amount of 0.07% for the fiscal year ended June 30, 2026.

 

(2)Magellan Investment Partners North America, Inc. (“MIPNA”), the Fund’s investment adviser, has contractually agreed to waive its management fee and/or reimburse the Fund’s operating expenses to the extent necessary to ensure that the Fund’s total operating expenses (excluding taxes, interest, brokerage commissions, acquired fund fees and expenses (“AFFE”) and extraordinary expenses) do not exceed 0.50% and 0.65% of the Fund’s average daily net assets attributable to the Institutional Class and Service Class shares, respectively. MIPNA is entitled to recoup the fees waived and/or expenses reimbursed within a three-year period from the date of the waiver or expense payment if such reimbursement will not cause the Fund’s expense ratio to exceed the lesser of: (a) the expense limitation in place at the time of the waiver and/or expense payment; or (b) the expense limitation in place at the time of the recoupment. The expense cap/reimbursement agreement will continue in effect until October 31, 2028, and may be terminated only by, or with the consent of, the Board of Directors of the Company.

Expense Example Narrative [Text Block]

The following example is intended to help you compare the cost of investing in the shares of 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 remain the same. The fee waiver/expense reimbursement arrangement included in the table above is reflected only through October 31, 2028.

Expense Example by, Year, Caption [Text] 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 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 21% of the average value of its portfolio.
