(1) Management Fees include fees payable to the Investment Manager for advisory services and for supervisory, administrative and other services. The Fund pays for the advisory, supervisory and administrative services it requires under what is essentially an all-in fee structure (the “unified management fee”). Pursuant to an investment management agreement, PIMCO is paid a Management Fee of 0.65% based on the Fund’s average daily net assets (including daily net assets attributable to any preferred shares of the Fund that may be outstanding). The Fund (and not PIMCO) will be responsible for certain fees and expenses, which are reflected in the table above, that are not covered by the unified management fee under the investment management agreement. Please see “Management of the Fund– Investment Management Agreement” in the accompanying Prospectus for an explanation of the unified management fee. (2) Reflects the Fund’s outstanding preferred shares averaged over the fiscal year ended June 30, 2024, which represented 0.22% of the Fund’s total average managed assets (including the liquidation preference of outstanding preferred shares and assets attributable to reverse repurchase agreements), as of that date, at an annual dividend cost to the Fund of 6.82%. The Fund repurchased the bulk of its preferred shares in a tender offer completed in April 2024 and redeemed its remaining preferred shares between November 4, 2024 and November 8, 2024. The Fund has no preferred shares outstanding as of the date of this prospectus supplement.

(3) Reflects the Fund’s use of leverage in the form of reverse repurchase agreements averaged over the fiscal year ended June 30, 2024, which represented 17.05% of the Fund’s total average managed assets (including assets attributable to reverse repurchase agreements), at an annual interest rate cost to the Fund of 5.73%, which is the weighted average interest rate cost during the fiscal year ended June 30,
