Approximately 175,000 and 137,000 restricted stock units for the three months ended March 31, 2017 and March 31, 2016, respectively, have been excluded from diluted weighted average common shares outstanding since a performance condition on these awards was not met in each of the respective periods. The Company did not include performance restricted stock units in the calculation of diluted EPS, since the performance conditions for these awards were not met.
