Outstanding options of 1,059 thousand as of June 30, 2012 and 774 thousand as of June 30, 2011 were not included in the computation of diluted earnings per share because their exercise prices were greater than the average market price of our common stock during the respective periods and their inclusion would, therefore, have been anti-dilutive.  Since we had a net loss for the six-month period ended June 30, 2011, basic and diluted net loss per share of common stock is the same, because the effect of including potential common stock equivalents (such as stock options, restricted shares, and restricted stock units) would be anti-dilutive.  The effect of dilutive securities would have been 813 thousand on weighted average number of common shares outstanding for the six months ended June 30, 2011.
