[1] For purposes of calculating compensation cost recognized, we consider awards effectively vested (and we recognize the full compensation costs) when grantees become retirement eligible. Under the terms of our awards, legal vesting upon retirement occurs when the grantee actually separates from service, except for awards granted to certain senior executives in which case vesting remains dependent on performance for the full term of the awards notwithstanding an executive’s early retirement.
