|Income Tax Disclosure [Abstract]
In order to determine the quarterly provision for income taxes, the Company used an estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. The income tax provision consists primarily of income taxes related to the Company's operations in foreign jurisdictions as well as accruals for tax contingencies. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter.
As the Company does not believe that it is more-likely-than-not that it will realize a benefit from its U.S. net deferred tax assets, including its U.S. net operating losses, the Company continues to provide a full valuation allowance against those assets and therefore does not incur significant U.S. income tax expense or benefit. Additionally, the Company completed the acquisition of Entropic Communications in the second quarter of 2015. As a result of the acquisition, there was a valuation allowance release that resulted in a tax benefit of $1.6 million due to the purchase accounting adjustment for the net deferred tax liability. Furthermore, the Company does not incur expense or benefit in the certain tax free jurisdictions in which it operates.
The Company recorded a provision for income taxes of $0.5 million and a benefit of $0.6 million for the three and nine months ended September 30, 2015, respectively. The Company recorded a provision for income taxes of $0.03 million and $0.5 million for the three and nine months ended September 30, 2014, respectively. The provision (benefit) for income taxes for the three and nine months ended September 30, 2015 and 2014 primarily relates to income taxes in certain foreign jurisdictions.
During the nine months ended September 30, 2015, the Company’s unrecognized tax benefits increased by $1.9 million which includes an amount of $1.5 million related to the acquisition of Entropic. The Company does not anticipate its unrecognized tax benefits will change significantly over the next 12 months. Accrued interest and penalties associated with uncertain tax positions as of September 30, 2015 were $0.05 million and $0.02 million, respectively.
The Federal examination by the Internal Revenue Service for the years 2010 and 2011 was completed during the three months ended March 31, 2014. Any impact from the audit was included in the 2013 financial statements. The Company is not currently under examination in any other jurisdictions.
