Quarterly Results (Unaudited) [Abstract] |
Quarterly Results (Unaudited) | 16. Quarterly Results (Unaudited) The following quarterly results have been derived from our audited annual consolidated financial statements. In the opinion of management, this unaudited quarterly information has been prepared on the same basis as the annual consolidated financial statements and includes all adjustments, including normal recurring adjustments, necessary for a fair presentation of this quarterly information. This information should be read along with the financial statements and related notes. The operating results for any quarter are not necessarily indicative of results to be expected for any future period. The unaudited quarterly statement of operations data for each quarter of fiscal years 2012 and 2011 were as follows (in thousands, except per share data):

(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.
