Insights

Corporate Insider / Compensation Analyst

Routine compensation-related stock settlement: 45.8693 DERs converted to shares on 09/30/2025.

The filing records a non-cash settlement of dividend equivalent rights tied to existing restricted stock units; such DERs are the economic equivalent of one share each and vest with the underlying RSUs. The transaction shows no cash purchase (price listed as $0), indicating this was an automatic settlement under the company’s equity compensation plan rather than an open-market buy.

The reporting person’s post-transaction beneficial ownership is 45,751.7837 shares, which is a disclosure detail for insider holdings but does not by itself indicate a change in control or a separate cash-based investment.
