Under net settlement procedures currently applicable to our outstanding restricted stock awards for employees, upon each settlement date and election by the employees, restricted stock awards are withheld to cover the required withholding tax, which is based on the value of the restricted stock award on the settlement date as determined by the closing price of our Class A common stock on the trading day immediately preceding the applicable settlement date. The remaining amounts are delivered to the recipient as shares of our Class A common stock.
