(1) Amounts include the reclassification of foreign currency exchange rate gains (losses) to other income in the consolidated financial statements. Prior to the fourth quarter of 2014, these amounts were reported as a component of other expenses.

(2) Since the weighted-average number of shares outstanding for the quarters are calculated independently of the weighted-average number of shares outstanding for the year, quarterly net income per share may not total to annual net income per share.
