As reported in the company's DEF 14A Summary Compensation Table (SEC Reg S-K Item 402(c)). Stock and option awards are grant-date fair values — what the award was worth on the day it was granted, not cash received and not what it is worth now. Every row here reconciles: its columns add up to the total the filing printed.

Invested = shares acquired (buys, grants, option exercises) — insider adding to the position. Divested = shares reduced (sells, dispositions, tax-withholding) — cash flowing TO the insider. Net direction shows which side wins on dollar terms in each bucket. % of holder's stake not yet computed (pending Form 3/4 holdings ingest). See methodology. The two @ last price columns restate the same share counts at the most recent share price we read (close of 2026-10-30); they are a valuation, not a cash flow, and they move every day the market does.
