Ranking Methodology & Sources
Tenure duration is measured in continuous days from the formal date of appointment as Chief Executive Officer to the official date of resignation, retirement, or departure. Interim terms are noted separately. Every data point is independently audited against regulatory filings (such as SEC Form 8-K, 10-K, and DEF 14A proxy statements).
