(11)     Income Taxes

Interim income taxes are based on an estimated annualized effective tax rate applied to the respective quarterly periods, pro forma for discrete tax items in the period in which they occur. For the three months ended September 30, 2011 and 2010, the Company’s (benefit) provision for income taxes, as a percentage of income (loss) before income taxes was (42.2) percent and 37.0 percent, respectively, compared with a U.S. federal statutory rate of 35.0 percent. For the nine months ended September 30, 2011 and 2010, the Company’s provision for income taxes, as a percentage of income before income taxes was 14.1 percent and 12.3 percent, respectively, compared with a U.S. federal statutory rate of 35.0 percent.

The differences between the effective tax rates and the U.S. federal statutory tax rate for the three months and nine months ended September 30, 2011 was primarily attributed to foreign deductible items, including a favorable inflation adjustment, and lower rates in foreign jurisdictions than the rates in the U.S., in addition to a decrease in recognition of previous expense related to unremitted earnings.

The differences between the effective rate and the U.S. federal statutory rate for the three and nine months ended September 30, 2010 were primarily attributed to net increases in tax liabilities associated with uncertain tax positions offset by deductions of certain worthless foreign stock, and also offset by utilization of foreign tax credits.

The Company’s U.S. federal income tax returns for 2003 through 2010 are open to examination for federal tax purposes. The Company has several foreign tax jurisdictions which have open tax years from 2000 through 2010. The Internal Revenue Service (“IRS”) is currently conducting an audit of the Company’s U.S. federal income tax returns for 2006 through 2010.

As of September 30, 2011, the Company had accrued $12,872 (net of $5,687 of other assets related to competent authority and royalty benefits) related to unrecognized tax positions compared with $15,679 (net of $5,687 of other assets related to competent authority and royalty benefits) as of December 31, 2010. This net decrease was primarily attributed to the expiration of the statute of limitations on certain liabilities in various foreign jurisdictions and payments made during the quarter of $2,593 related to the IRS’s audits of the Company’s U.S. federal income tax returns for 2003 through 2005, which were expensed in prior periods.

In October 2009, the IRS issued an examination report formally proposing adjustments with respect to the 2003 through 2005 taxable years, which primarily relate to the prices that were charged in intra-group transfers of property and the disallowance of related deductions. The Company has commenced administrative proceedings with the Office of Appeals of the Internal Revenue Service challenging the proposed adjustments. Management believes that the Company has appropriately reserved for these matters, relating to all open periods, at an amount which it believes will ultimately be due upon resolution of the administrative proceedings, and such amounts reflect management’s estimates based upon available evidence resulting from discussions with the IRS Office of Appeals. These estimates are based upon a more-likely-than-not recognition threshold. The Company is currently unable to determine the outcome of these discussions and their related impact, if any, on the Company’s financial condition, results of operations, or cash flows.

Although the Company believes its estimates are reasonable, the Company can make no assurance that the final tax outcome of these matters will not be different from that which it has reflected in its historical income tax provisions and accruals.

Such difference could have a material impact on the Company’s income tax provision and operating results in the period in which the Company makes such determination.
