The restricted stock vests in one-third annual increments.&#160;&#160;Prior to vesting, each share of restricted stock is subject to forfeiture if the recipient ceases to render substantial services to OGE Energy or a subsidiary for any reason other than death, disability or retirement. These shares may not be sold, assigned, transferred or pledged and are subject to a risk of forfeiture.</font></div><div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify">&#160;</div><div style="TEXT-INDENT: 40pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt">The fair value of the restricted stock was based on the closing market price of OGE Energy&#8217;s common stock on the grant date. Compensation expense for the restricted stock is a fixed amount determined at the grant date fair value and is recognized as services are rendered by employees over a three-year vesting period. Also, the Company treats its restricted stock as multiple separate awards by recording compensation expense separately for each tranche whereby a substantial portion of the expense is recognized in the earlier years in the requisite service period. Dividends are accrued and paid during the vesting period and, therefore, are included in the fair value calculation. The expected life of the restricted stock is based on the non-vested period since inception of the three-year award cycle.&#160;&#160;There are no post-vesting restrictions related to OGE Energy&#8217;s restricted stock.&#160;&#160;The number of shares of restricted stock granted and forfeited and the grant date fair value are shown in the following table.</font></div><div style="TEXT-INDENT: 0pt;
