(1)Preferred dividends shown herein relate to the Company’s Series A Mandatorily Convertible Preferred Stock (“Series A Preferred Stock”) issued on October 1, 2012, which allows, at the Company’s option, for the 8% annual dividend payment to be made either in cash or through an adjustment to the Series A Preferred Stock liquidation preference. Pre-tax preferred stock dividend amounts for the years ended December 31, 2015 and 2014 were calculated utilizing the Company’s effective tax rate for the applicable periods (0.5% and 5.2%, respectively) and represent the notional dividend amount as though paid in cash, rather than through an adjustment to the Series A Preferred Stock liquidation preference. On September 30, 2015, the Series A Preferred Stock converted into 3,738,424 shares of common stock.
