Share-Based Compensation

The company's outstanding share-based compensation is comprised solely of restricted stock awards.

Restricted Stock Awards – Restricted stock awards are a grant of shares of common stock that may not be sold, encumbered or disposed of and that may be forfeited in the event of certain terminations of employment or in the case of the board of directors a separation for cause, prior to the end of a restricted period set by the Compensation Committee of the Board of Directors. A participant granted restricted stock generally has all of the rights of a stockholder, unless the Compensation Committee determines otherwise.
