The Fund’s investment advisor, TCW Investment Management Company LLC (the “Advisor”), has agreed to waive fees and/or reimburse expenses to limit the Fund’s total annual operating expenses (excluding interest, brokerage, extraordinary expenses and acquired fund fees and expenses, if any) to 0.80% of average daily net assets with respect to Class I shares, 0.88% of average daily net assets with respect to Class I-3, and 1.00% of average daily net assets with respect to Class N shares. The Advisor may recoup reduced fees and expenses within three years of the waiver or reimbursement, provided that the recoupment does not cause the Fund’s annual expense ratio to exceed (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 contractual fee waiver/expense reimbursement will remain in place through March 1, 2027 and before that date, the investment advisor may not terminate this arrangement
without approval of the Board of Directors. At the conclusion of this period, the Fund’s investment advisor may, in its sole discretion, terminate the contractual fee waiver/expense reimbursement or, with the Board of Directors’ approval, extend or modify that arrangement.
