Singapore and Thailand that expire at various dates through 2025 and the current year generation of income tax cred-
benefits related to liabilities assumed in the Acquisition, we recognized a net decrease of $4 million in our liability for
unrecognized tax benefits during 2012. Interest and penalties recognized on such amounts were not material.

agreement resulted in an immaterial benefit to our income tax provision. We have also received RARs from the IRS
that seek adjustments to income before income taxes of approximately $970 million in connection with unresolved
issues related primarily to transfer pricing and intercompany payable balances. We disagree with the proposed

operations as well as our available credit facilities will be sufficient to meet our working capital, debt, dividend, stock
repurchase and capital expenditure needs for at least the next twelve months. Our ability to sustain our working capi-
tal position is subject to a number of risks that we discuss in Item 1A of this Annual Report on Form 10-K.
