Potential dilutive shares are excluded from the computation of EPS if their effect is anti-dilutive. Options to purchase an additional 225,000, 205,000, and 1,311,433 were not included in the computation of diluted EPS at December 31, 2015, 2014, and 2013, respectively, because the incremental shares under the treasury stock method of calculation resulted in them being antidilutive.
