Total annual fund operating expenses do not correlate with the ratios of expenses to average net assets reported in the fund’s financial highlights tables, which reflect the fund’s operating expenses and do not include acquired fund fees and expenses.
[2]
The manager has agreed to waive fees and/or reimburse operating expenses (other than interest, brokerage commissions, taxes, extraordinary expenses, deferred organizational expenses and acquired fund fees and expenses), so that the ratio of total annual fund operating expenses will not exceed 1.07% for Class A shares, 1.80% for Class C shares, 1.10% for Class FI shares, 1.35% for Class R shares, 0.75% for Class I shares and 0.65% for Class IS shares, subject to recapture as described below. In addition, the ratio of total annual fund operating expenses for Class IS shares will not exceed the ratio of total annual fund operating expenses for Class I shares, subject to recapture as described below. These arrangements cannot be terminated prior to December 31, 2027 without the Board of Directors’ consent. The manager is permitted to recapture amounts waived and/or reimbursed to a class within two years after the fiscal year in which the manager earned the fee or incurred the expense if the class’ total annual fund operating expenses have fallen to a level below the limits described above. In no case will the manager recapture any amount that would result, on any particular business day of the fund, in the class’ total annual fund operating expenses exceeding the applicable limits described above or any other lower limit then in effect. In addition, the manager has agreed to waive the fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund. This management fee waiver is not subject to the recapture provision discussed above.

Total annual fund operating expenses (after waiving fees and/or reimbursing expenses, as applicable) are higher than the expense cap amounts for each class as a result of acquired fund fees and expenses.
