7. Income Taxes

The Benefit from income taxes decreased by $42.1 million and $8.8 million in the three and nine months ended September 30, 2013, respectively, as compared to the same period of the prior year. The decrease in the three months ended September 30, 2013 is attributable primarily to the tax impact of the OMGPOP impairment charge of $39.1 million recorded in the third quarter of 2012. In the nine months ended September 30, 2013, this $39.1 million year-over-year decrease was partially offset by a benefit of $12.4 million recorded in the first quarter of 2013 related to the reinstatement of the federal research and development tax credit retroactive to January 1, 2012, and a benefit of $16.3 million recorded in the second quarter of 2013 related to changes in the estimated jurisdictional mix of earnings.

During 2012, we completed the implementation of our international structure, which resulted in a significant loss outside of the U.S for which no benefit was recorded. If and when the Company is profitable, we expect our global effective tax rate to be less than the U.S. statutory income tax rate.
