Income Taxes

The Company recorded income tax expense (benefit) of $761 and $(2,255) for the three months ended June 28, 2014 and June 29, 2013, respectively. The Company recorded income tax (benefit) of $(936) and ($10,256) for the six months ended June 28, 2014 and June 29, 2013, respectively. The income tax expense for the three months ended June 28, 2014 was primarily the result of the Company's pre-tax income, offset by the recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises in the quarter. The income tax benefit for the six months ended June 28, 2014 is primarily the result of the Company's recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises. The income tax benefit for the three and six months ended June 29, 2013 was primarily the result of the Company's pre-tax loss, and the recognition of U.S. federal tax credits.

As of June 28, 2014, the U.S. Congress had not extended the general business credit for research and experimentation. The Company has not estimated the effect of the expiration of this credit, nor does the income tax expense for the three and six months ended June 28, 2014 reflect a benefit for the credit.

No provision has been made for the U.S., state or additional foreign income taxes related to approximately $70,500 of undistributed earnings of foreign subsidiaries which have been permanently reinvested outside the U.S. except for existing earnings that have been previously taxed. In the event of repatriation, which would generally require board approval, the earnings may be subject to an estimated $25,000 of U.S. federal and state income taxes and foreign withholding taxes.

The major jurisdictions in which the Company files tax returns are the United States, Singapore and Costa Rica. In 2012, the Company expanded its presence into Asia by increasing operations in Singapore. Due to agreements with the Costa Rican and Singaporean governments, the Company was granted income tax holidays of varying rates through March 2017 and December 2019, respectively. Incentives from these countries are subject to the Company meeting certain employment and investment requirements. The Company was in compliance with these requirements as of June 28, 2014.

Deferred Income Taxes

As of June 28, 2014, deferred tax assets of $77,661, net of a $16,243 valuation allowance, were recorded on the balance sheet. As of December 31, 2013, the Company had deferred tax assets of $74,341, net of a $16,639 valuation allowance. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more-likely-than-not to be realized. The Company maintains a valuation allowance against the tax effect of all capital loss carryforwards, certain state and foreign net operating loss carryforwards, and certain state credit carryforwards, as management does not believe it is more likely than not that these benefits will be realized in future periods.

Unrecognized Tax Benefits

In the six months ended June 28, 2014, net unrecognized tax benefits increased $1,934 primarily as a result of an additional liability recorded to address existing potential exposures from positions that could be challenged by taxing authorities. Within the next 12 months, the Company believes it is reasonably possible that $1,460 of net unrecognized tax benefits may be reduced as a result of the expiration of a statute of limitations. Interest and penalties associated with unrecognized tax benefits are accrued and classified as a component of tax expense in the statement of operations and comprehensive loss.

Net unrecognized tax benefits at June 28, 2014 and December 31, 2013 were as follows:
