Earnings Per Share [Abstract]

Earnings Per Share (EPS)

Earnings Per Share (EPS)

Basic EPS is calculated by dividing Net earnings attributable to IR-Ireland by the weighted-average number of ordinary shares outstanding for the applicable period. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potentially dilutive ordinary shares, which in the Company’s case, includes shares issuable under share-based compensation plans and the effects of the Exchangeable Senior Notes settled in April 2012. The following table summarizes the weighted-average number of ordinary shares outstanding for basic and diluted earnings per share calculations for the three and six months ended June 30:

	Three months ended		Six months ended
In millions	2013	2012	2013	2012
Weighted-average number of basic shares	297.5	309.2	298.1	304.2
Shares issuable under incentive stock plans	3.7	3.5	3.8	3.2
Exchangeable Senior Notes	—	1.7	—	6.1
Weighted-average number of diluted shares	301.2	314.4	301.9	313.5
Anti-dilutive shares	1.1	5.8	1.4	6.4

The Company settled all remaining outstanding Exchangeable Senior Notes in April 2012. As a result, the Company paid $357.0 million in cash and issued 10.8 million ordinary shares to settle the principal, interest and equity portion of the notes.
