(1) The Total Annual Fund Operating Expenses may not equal the expense ratio stated in the Fund’s most recent annual report and financial highlights. The expense ratio in the financial highlights reflects the operating expenses of the Fund and does not include indirect expenses associated with the Fund’s investments in other money market funds (acquired fund fees and expenses). Without acquired fund fees and expenses, Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement would have been 0.48%, 0.13%, 0.18%, 0.20%, 0.18% and 0.23% for Class A Shares, Class I Shares, Intermediary Shares, Intermediary Service Shares, Class P Shares and Class Y Shares, respectively.

Any amounts contractually waived or reimbursed by the Adviser will be subject to repayment by the Fund to the Adviser within three years, calculated monthly from when the waiver or reimbursement was recorded, to the extent that the repayment will not cause the Fund’s operating expenses to exceed the contractual expense limit that was in effect at the time of such waiver or reimbursement. The expense limitation shall be in effect until February 28, 2027. The Expense Limitation Agreement shall terminate upon the termination of the Investment Advisory Contract between the Fund and the Adviser, or it may be terminated upon written notice to the Adviser by the Trust’s Board of Trustees.
