Insights

Corporate Governance Expert

Director accrued 4.4487 DERs tied to RSUs; holdings now 10,328.0781 shares.

The transaction is recorded as a Code V event, indicating the acquisition is the economic equivalent of dividends on existing restricted stock units rather than a market purchase.

This is an administrative accumulation of dividend-equivalent rights at $0, not a cash purchase or open-market trade; it adjusts the director's deferred compensation tied to equity awards.
