(1)   In connection with the preparation of the Company’s unaudited condensed consolidated financial statements for the quarter ended September 30, 2013, the Company determined that its convertible subordinated notes were incorrectly included as dilutive securities using the “if-converted” method in the calculation of diluted earnings per share for the nine months ended September 30, 2012. Accordingly, the Company has corrected its calculation of diluted earnings per share for the nine months ended September 30, 2012 as presented herein to report diluted earnings per share of $0.14, which was previously reported in its quarterly report on Form 10-Q for the nine months ended September 30, 2012 as $0.18 per diluted share.
