Stock split, effective June 28, 2013	On May 24, 2013, the Board of Directors of the Company approved a two-for-one split of our common stock in the form of a one hundred percent (100%) stock dividend, which was distributed on or about June 28, 2013 to shareholders of record as of June 17, 2013. In connection with the stock split, 1.5 million treasury shares (pre-split), which represents the amount held in treasury on June 28, 2013, were utilized to settle a portion of the distribution.
