[1] In 2016, authoritative guidance required forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Throughout 2016, forfeitures were estimated at 3% and the actual forfeiture rate was 6% for 2016. The Company adjusted stock compensation expense for 2016 based on the actual forfeiture rate.
