[2] Metropolitan West Asset Management, LLC (the “Adviser”) has contractually agreed to reduce advisory fees and/or reimburse expenses, including distribution expenses, to limit the Fund’s total annual operating expenses (excluding interest, taxes, brokerage commissions, short sale dividend expenses, swap interest expenses, acquired fund fees and expenses, and any expenses incurred in connection with any merger or reorganization or extraordinary expenses such as litigation) to 0.70% of average daily net assets with respect to Class M shares, 0.49% of average daily net assets with respect to Class I shares, 0.54% of average daily net assets with respect to Class I-2 shares, 0.59% of average daily net assets with respect to Class I-3 shares, 0.90% of average daily net assets with respect to Administrative Class shares, and 0.39% of average daily net assets with respect to Plan Class shares. The Adviser may recoup reduced fees and expenses only within three years of the waiver or reimbursement, provided that the recoupment does not cause the Fund’s annual expense ratio to exceed the lesser of (i) the expense limitation applicable at the time of that fee waiver and/or expense reimbursement or (ii) the expense limitation in effect at the time of recoupment. This contract will remain in place through July 31, 2027. Although it does not expect to do so, the Board of Trustees is permitted to terminate that contract sooner in its discretion with written notice to the Adviser.
