[1] | The $39.5 million tax benefit recorded in the fourth quarter of 2012 favorably impacted net income, as a result of a $37.3 million release in valuation allowance on deferred tax assets.
[2] | Net income was favorably impacted by a $117.0 million benefit to tax expense to decrease the valuation allowance on our U.S. deferred tax assets, which was partially offset by reduced gross margins attributable to a charge of approximately $4.2 million due to a production issue with a new audio device that entered high volume production in March 2011.
