Industry Context

This filing represents a routine insider transaction common in publicly traded companies when executives retire. It reflects the standard process for equity compensation vesting and tax compliance, aligning with typical corporate governance practices for executive departures in the consumer packaged goods industry.

Comparison to Industry Standards

• The accelerated vesting of RSUs upon retirement is a common provision in executive compensation plans across various industries, including consumer staples, to ensure executives are compensated for their service up to their departure.
• The surrender of shares for tax withholding is a standard mechanism for satisfying tax obligations on equity awards, consistent with practices at comparable companies like General Mills (GIS), Kellogg Company (K), or Conagra Brands (CAG) when their executives receive or vest equity compensation.
• The six-month delay in settlement due to Section 409A of the IRC is a standard regulatory compliance measure for non-qualified deferred compensation plans, widely observed across all industries for executives in similar situations.
