F1	Issued as deferred stock units (DSUs) in connection with reporting person's retainer as a director under the Company's 2023 Equity Incentive Plan and exempt from Section 16(b) by virtue of Rule 16b-3(d)(1) and (3). These DSUs are reportable, however, as directly owned shares of common stock, rather than as a derivative security in Table II, because any and all underlying DSUs are payable, at such time as they are to be settled, solely in common stock. See Lincoln National Corp. (March 20, 1992) (Q.3). The DSUs vest as follows: 1/4 on 8/31/2025, 1/4 on 11/30/2025, 1/4 on 2/28/2026 and 1/4 on 5/31/2026.
