10. Income Taxes

To calculate its interim tax provision, at the end of each interim period the Company estimates the annual effective tax rate and applies that to its ordinary quarterly earnings. In addition, the effect of changes in enacted tax laws or rates or tax status is recognized in the interim period in which the change occurs. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in foreign jurisdictions, permanent and temporary differences between book and tax amounts, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or as the tax environment changes.

The Company recognizes interest and penalties related to uncertain tax positions as a component of the income tax provision. The Company's unrecognized tax benefits increased $0.1 million during the three months ended March 31, 2012. The increase in unrecognized tax benefits during the three months ended March 31, 2012 was primarily related to an increase related to state research credits. The unrecognized tax benefits at March 31, 2012 were $4.3 million. With the facts and circumstances currently available to the Company, it is reasonably possible that $0.2 million of the Company's unrecognized tax benefits could decrease within the next 12 months due to the expiration of statutes of limitations or tax examination settlement.

The income tax provision consists primarily of income tax provisions related to acquired Scient'x operations, state income taxes, and the tax effect of changes in deferred tax liabilities associated with tax deductible goodwill offset by operations in Japan.

The Company is not currently under examination by the IRS. The Company has been contacted by the state of Texas and will be undergoing an exam of the 2009 year. A subsidiary of Scienti'x's 2008, 2009 and 2010 tax years are currently under audit by the French tax authorities. No adjustments have been proposed that will have a material impact on the Statement of Operations.
