X

- Definition

Period from date of grant when grantee's right to exercise award under share-based payment arrangement is no longer contingent on satisfaction of service or performance condition, in 'PnYnMnDTnHnMnS' format, for example, 'P1Y5M13D' represents the reported fact of one year, five months, and thirteen days. A grantee becomes fully vested on a specified date rather than becoming partially vested in increasing amounts over an extended period.
