Tax Holidays and Carryforwards
A substantial portion of the Company’s manufacturing operations in Malaysia, the Philippines, Singapore and
Thailand operate under various tax holidays and tax incentive programs which will expire in whole or in part at vari-
ous dates from 2014 through 2025. Certain of the holidays may be extended if specific conditions are met. The net
impact of these tax holidays and tax incentives was to increase the Company’s net earnings by $899 million ($3.65 per
diluted share), $729 million ($2.98 per diluted share), and $362 million ($1.54 per diluted share) in 2013, 2012 and
2011, respectively.
As of June 28, 2013, the Company had federal and state NOL carryforwards of $309 million and $205 million,
respectively. In addition, as of June 28, 2013, the Company had various federal and state tax credit carryforwards of
$271 million combined. The NOL carryforwards available to offset future federal and state taxable income expire at
various dates from 2020 to 2032 and 2017 to 2031, respectively. Approximately $42 million of the credit carryfor-
wards available to offset future taxable income expire at various dates from 2016 to 2031. The remaining amount is
available indefinitely. NOLs and credits relating to Komag, Incorporated (“Komag”), which was acquired by the
Company on September 5, 2007, and HGST, which was acquired by the Company on March 8, 2012, are subject to
limitations under Section 382 and 383 of the Internal Revenue Code. The Company does not expect these limitations
to result in a reduction in the total amount of Komag’s NOLs and credits ultimately realized. The Company expects
the total amount of HGST’s NOLs and credits ultimately realized will be reduced by $39 million and $33 million,
respectively. Because the Company expects the amount of HGST’s NOLs and credits ultimately realized will be
reduced, the Company has adjusted the goodwill accordingly.
Uncertain Tax Positions
The Company recognizes liabilities for uncertain tax positions based on a two-step process. First, the tax position
is evaluated for recognition by determining if it is more likely than not that the position will be sustained on audit,
including resolution of related appeals or litigation processes, if any. If the tax position is deemed more-likely-than-
not to be sustained, the tax position is then assessed to determine the amount of benefit to be recognized in the finan-
cial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50%
likelihood of being realized upon ultimate settlement. With the exception of certain unrecognized tax benefits that
are directly associated with the tax position taken, unrecognized tax benefits are presented gross in the Company’s
balance sheet. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for
uncertain tax positions and are recorded in the provision for income taxes. As of June 28, 2013, such interest and
penalties were not material. As of June 28, 2013, the Company had $240 million of unrecognized tax benefits.
