NET INCOME PER SHARE (Notes)

12 Months Ended

Dec. 31, 2015

Net income per common share is presented for both basic income per share (“Basic EPS”) and diluted income per share (“Diluted EPS”). Basic EPS is based on the weighted-average number of common shares outstanding during the period. Diluted EPS is based on the weighted-average number of common shares and common shares equivalents outstanding during the period.

The potential common shares that were considered anti-dilutive securities were excluded from the diluted earnings per share calculations for the relevant periods either because the sum of the exercise price per share and the unrecognized compensation cost per share was greater than the average market price of the Company’s common stock for the relevant period, or because they were considered contingently issuable. The contingently issuable potential common shares result from certain stock options and restricted stock units granted to the Company’s employees that vest based on performance conditions, market conditions, or a combination of performance or market conditions.

The following table sets forth (in thousands) potential common shares that were considered anti-dilutive securities.

On June 15, 2015, the Company issued $125.0 million aggregate principal amount of its 2.00% Convertible Senior Notes due 2020 (the “Notes”). The Notes are convertible into cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election, based on an initial conversion rate, subject to adjustment. In connection with the offering of the Notes, the Company entered into a capped call transaction with a third party (the “Capped Call”) (see Note R, Long-Term Debt and Credit Agreement). The Company uses the treasury stock method in computing the dilutive impact of the Notes. The Notes are convertible into shares but the Company’s stock price was less than the conversion price at December 31, 2015, and therefore, the Notes are excluded from diluted income per share. The Capped Call is not reflected in diluted net income per share as it will always be anti-dilutive.
