Income Taxes

The Company recognized $0.1 million of income tax benefit relating to refundable credits for the three and nine months ended September 30, 2012 and there was no material income tax expense for the three and nine months ended September 30, 2011. The Company's effective tax rate will fluctuate from period to period due to several factors inherent in the nature of the Company's operations and business transactions. The factors that most significantly impact this rate include the variability of licensing transactions in foreign jurisdictions.
