On March 31, 2026 he was credited with 15.725 DEUs and 18.156 DEUs (total 33.881 units).

Context
DEUs are a routine mechanism that accrues additional RSUs when the company pays cash dividends on outstanding RSUs. This is not a cash purchase or sale and does not by itself indicate a change in insider sentiment. The additional units remain subject to the same vesting and restrictions as the original RSU grants.
