Restricted Stock Grants
Time-based restricted stock awards are comprised of time-based restricted stock units. These awards vest over three years; however, they may be accelerated to vest over one year if the Company meets pre-established performance goals in the year of grant. Time-based restricted stock units receive dividend equivalents in the form of additional time-based restricted stock units, which are subject to the same restrictions and forfeiture provisions as the original award.
Performance-based restricted stock awards include performance-based restricted stock units. These awards cliff vest at the end of a three year period based upon the Company’s achievement of pre-established goals throughout the term of the award. Performance-based restricted stock units receive dividend equivalents in the form of additional performance-based restricted stock units, which are subject to the same restrictions and forfeiture provisions as the original award. The grant date fair value of restricted stock awards is based on the closing market price of the Company’s common stock on the date of grant.
