⁽¹⁾	Share and per share amounts have been retroactively restated for all prior periods presented to reflect the five-for-one split of the Company’s common stock effected in the form of a stock dividend that was distributed on June 17, 2015.

In the computation of diluted earnings per common share, potentially dilutive stock options are excluded if the effect of their inclusion is anti-dilutive. For the years ended December 31, 2015, 2014 and 2013, anti-dilutive stock options were insignificant.
