On a consolidated basis, the Company has incurred operating losses and has recorded a full valuation allowance against its United States and United Kingdom deferred tax assets for all periods to date and, accordingly, has not recorded a provision (benefit) for income taxes for any of the periods presented other than a provision (benefit) for certain foreign income taxes. Certain foreign subsidiaries and branches of the Company provide intercompany services and are compensated on a cost-plus basis, and therefore, have incurred liabilities for foreign income taxes in their respective jurisdictions. The foreign deferred tax benefit for the years ended December 31, 2013 and 2012 is primarily the result of the amortization of net deferred tax liabilities and changes in other deferred taxes recorded in connection with the 2012 acquisition of Sonar (See Note 3).

At December 31, 2013, the Company had federal, state and foreign net operating losses of approximately $145.8 million, $152.8 million and $18.0 million, respectively. The federal net operating loss carryforward will begin expiring in 2019, the state net operating loss carryforward began expiring in 2013, and the foreign net operating loss has an unlimited carryforward period. The Internal Revenue Code of 1986, as amended, imposes substantial restrictions on the utilization of net operating losses in the event of an “ownership change” of a corporation. Accordingly, a company’s ability to use net operating losses may be limited as prescribed under Internal Revenue Code Section 382 (“IRC Section 382”). Events which may cause limitations in the amount of the net operating losses that the Company may use in any one year include, but are not limited to, a cumulative ownership change of more than 50% over a three-year period. Due to the effects of historical equity issuances, the Company has determined that the future utilization of a portion of its net operating losses is limited annually pursuant to IRC Section 382. The Company has determined that none of its net operating losses will expire because of the annual limitation.

The Company has recorded a full valuation allowance against its otherwise recognizable United States and United Kingdom deferred income tax assets as of December 31, 2013. Management has determined, after evaluating all positive and negative historical and prospective evidence, that it is more likely than not that these assets will not be realized. The net increase to the valuation allowance of $14.5 million, $7.4 million and $7.2 million for the years ended December 31, 2013, 2012 and 2011, respectively, was primarily due to additional net operating losses generated by the Company and basis differences in long-lived assets.

The Company has excluded excess windfall tax benefits resulting from stock option exercises as components of the Company’s gross deferred tax assets and corresponding valuation allowance disclosures, as tax attributes related to such windfall tax benefits should not be recognized until they result in a reduction of taxes payable. The tax effected amount of gross unrealized net operating loss carryforwards, and their corresponding valuation allowances resulting from stock option exercises was $25.8 million at December 31, 2013. When realized, excess windfall tax benefits are credited to additional paid-in capital. The Company follows the with-and-without allocation approach to determine when such net operating loss carryforwards have been realized.

Deferred income taxes have not been provided on the undistributed earnings of the Company’s foreign subsidiaries because the Company’s practice and intent is to permanently reinvest these earnings. The cumulative amount of such undistributed earnings was $0.9 million and $0.5 million at December 31, 2013 and December 31, 2012, respectively. Any future distribution of these non-U.S. earnings may subject the Company to both U.S. federal and state income taxes, as adjusted for tax credits, and foreign withholding taxes that the Company estimates would be $125,000 and $76,000 at December 31, 2013 and 2012, respectively.

A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2013, 2012, and 2011 is as follows (in thousands):



	Years Ended December 31,
	2013		2012		2011
Balance at January 1	$	276	$	276	$	276
Additions for tax positions related to the current year	—		—		—
Balance at December 31	$	276	$	276	$	276

The provision for uncertain tax positions relate to business in territories outside of the United States.

The Company’s policy is to classify interest and penalties on uncertain tax positions as a component of tax expense. An insignificant amount of interest and penalties on unrecognized tax benefits were accrued during the 2013 tax year. The amount of accrued interest and penalties on unrecognized tax benefits was insignificant, as of December 31, 2013 and 2012. The Company does not expect the change in uncertain tax positions to have a material impact on its financial position, results of operations or liquidity. The recognition of previously unrecognized tax benefits on uncertain positions would result in a $0.3 million tax benefit. The Company does not expect any significant increases or decreases to its unrecognized tax benefits within the next twelve months.

The Company is subject to United States federal income tax as well as to income tax in multiple state and foreign jurisdictions, including the United Kingdom. Federal income tax returns of the Company are subject to IRS examination for the 2010 through 2013 tax years. State income tax returns are subject to examination for the 2009 through 2013 tax years. The Company finalized an IRS examination for the 2011 tax year which did not result in any material adjustments. Foreign income tax returns are subject to examination for the 2007 through 2013 tax years.
