Compensation & Benefits Analyst

TL;DR: Modest director compensation recorded as phantom units; typical practice for cash-settled director deferrals.

The transaction reflects routine director compensation bookkeeping: accrual of 6.963 phantom stock units under the Non-Funded Deferred Compensation and Unit Award Plan. Because settlement is in cash upon termination, this is a deferred cash liability for the company rather than equity issuance.
