[1] The Company early adopted ASU 2016-09 on a prospective basis as required, related to the recognition of excess tax benefits to the income statement which were previously recorded in additional paid-in capital, effective January 1, 2016. This resulted in an additional 456,352 and 436,288 diluted weighted average number of common shares outstanding for the three and six months ended June 30, 2016, respectively, and recognition of excess tax benefits of $9.6 million in net earnings from continuing operations and $1.0 million in net earnings from discontinued operations for the six months ended June 30, 2016 (there was no impact for the three months ended June 30, 2016). As a result, net earnings per common share increased by $0.05 per share for the six months ended June 30, 2016 and no impact for the three months ended June 30, 2016.
