Insights

Equity compensation analyst

Routine Form 4 showing non-cash CSE distribution and minor share increase.

The filing records a director receiving 100 common shares at $0, tied to an immediate distribution of Common Stock Equivalents (CSEs). This is typical for director compensation under a long-term incentive plan and reflects a conversion rather than an open-market purchase.

Derivative holdings decreased from 1,163 to 1,063 CSEs, consistent with a 100-unit distribution, while direct ownership rose to 30,178 shares. The filing also lists indirect holdings of 18,400 and 28,900 shares in two family trusts. Overall, these are administrative ownership updates without a quantified cash component.
