Earnings Per Share

Basic earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing income available to shareholders by the weighted-average number of shares outstanding during the period and the number of additional shares that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding options, unvested restricted share units and shares to be purchased under the ESPP. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in fair market value of the Company’s share price can result in a greater dilutive effect from potentially dilutive securities. The following table sets forth the computation of basic and diluted net income per share attributable to the shareholders of Seagate Technology plc:



	For the Three Months Ended
(In millions, except per share data)	September 27, 2013		September 28, 2012
Numerator:
Net income attributable to Seagate Technology plc	$	427	$	582
Number of shares used in per share calculations:
Total shares for purposes of calculating basic net income per share attributable to Seagate Technology plc	357		394
Weighted-average effect of dilutive securities:

Net income per share attributable to Seagate Technology plc shareholders:

The potential shares related to employee equity award plans were excluded from the computation of diluted net income per share attributable to Seagate Technology plc were immaterial for the three months ended September 27, 2013 and September 28, 2012, as their effect would have been anti-dilutive.
