[1] The sum of the quarterly net income per share amounts may not agree to the full year net income per share amounts. We calculate net income per share based on the weighted-average number of outstanding shares during the period for each reporting period presented. The average number of shares fluctuates throughout the year and can therefore produce a full year result that does not agree to the sum of the individual quarters.
