Insights

Corporate Governance Expert

TL;DR Director received deferred-compensation phantom stock that converts to shares upon departure; appears routine and non-voting.

The reported 10,227.219 phantom stock units represent dividend equivalents credited under Celanese’s 2008 Deferred Compensation Plan and convert to common stock upon the director’s termination of service. This is a compensation-related grant recorded on Form 4 rather than an open-market purchase or sale. As such, it signals alignment of compensation with equity value but is a routine director compensation event rather than a material corporate action.

Compensation Analyst

TL;DR Deferred dividend-equivalent units valued at $47.42 per unit were added to a director’s deferral account; this is typical for long-term compensation plans.

The Form 4 lists an acquisition designation for 10,227.219 phantom stock units with a table value of $47.42. The filing’s explanation explicitly describes these as dividend equivalents under the company’s deferred compensation plan that will be paid in shares after service termination. From a pay-structure perspective, this is consistent with aligning long-term director pay with shareholder outcomes and does not reflect current cash payouts or trading activity.
