The current year change in net deferred taxes of $1,827,000 is comprised of a net deferred expense of $548,000 related to the change in the basis difference of intangible assets with an indefinite life, a net deferred expense of $1,912,000 related to foreign and separate state jurisdictions for which no valuation allowance has been provided, and a $633,000 benefit related to foreign currency translation adjustments.

Deferred tax assets and liabilities result from temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are anticipated to be in effect at the time the differences are expected to reverse. The realization of the deferred tax assets, including the loss and credit carry forwards listed above, is subject to the Company generating sufficient taxable income during the periods in which the temporary differences become realizable. In accordance with the applicable accounting rules, the Company maintains a valuation allowance for a deferred tax asset when it is deemed to be more likely than not that some or all of the deferred tax assets will not be realized. In evaluating whether a valuation allowance is required under such rules, the Company considers all available positive and negative evidence, including prior operating results, the nature and reason for any losses, its forecast of future taxable income, and the dates on which any deferred tax assets are expected to expire. These assumptions require a significant amount of judgment, including estimates of future taxable income. These estimates are based on the Company’s best judgment at the time made based on current and projected circumstances and conditions.

In 2011, the Company performed an analysis to determine the likelihood that its deferred tax assets relating to its U.S. business would be realized. The Company considered its taxable loss in the U.S. in each of the past three years, the reasons for such loss, the Company’s projected financial forecast for its U.S business, and the dates on which the deferred tax assets were expected to expire. This evidence suggested that the Company should establish a valuation allowance. As a result, in 2011, the Company recorded a $52,455,000 increase to income tax expense in order to establish a valuation allowance against its U.S. deferred tax assets and discontinued recognizing income tax benefits related to its U.S. net operating losses. At December 31, 2013 and 2012, the valuation allowance against the Company’s U.S. deferred tax assets was $158,159,000 and $151,097,000, respectively. If sufficient positive evidence arises in the future, such as a sustained return to profitability, any existing valuation allowance could be reversed as appropriate, decreasing income tax expense in the period that such conclusion is reached. The Company has concluded that with respect to non-U.S. entities, there is sufficient positive evidence to conclude that realization of its deferred tax assets is more likely than not under applicable accounting rules, and no allowances have been established.

The non-cash charge to establish the valuation allowance in 2011 did not have any impact on the Company’s consolidated cash flows, nor will such an allowance preclude the Company from using loss carry forwards or other deferred tax assets in the future, except as described below. Until the Company re-establishes a pattern of continuing profitability, in accordance with the applicable accounting guidance, U.S. income tax expense or benefit related to the recognition of deferred tax assets in the consolidated statement of operations for future periods will be offset by decreases or increases in the valuation allowance with no net effect on the consolidated statement of operations.

At December 31, 2013, the Company has federal and state income tax credit carryforwards of $7,571,000 and $9,400,000 respectively, which will expire at various dates beginning in 2020. Such credit carryforwards expire as follows (in thousands):



U.S. foreign tax credit	$	4,102	2020 - 2023
U.S. research tax credit	$	3,455	2030 - 2033
U.S. business tax credits	$	14	2030 - 2033
State investment tax credits	$	872	Do not expire
State research tax credits	$	8,528	Do not expire

The Company has recorded a deferred tax asset reflecting the benefit of operating loss carryforwards. The net operating losses expire as follows (in thousands):



U.S. loss carryforwards	$	252,927	2031 - 2033
State loss carryforwards	$	176,106	2014 - 2033
Foreign loss carryforwards	$	178	Do not expire

In September 2013, the United States Department of the Treasury and the Internal Revenue Service ("IRS") issued final and proposed regulations for the tax treatment of tangible property. The final regulations include standards for determining whether and when a taxpayer must capitalize costs incurred in acquiring, maintaining, or improving tangible property. The final regulations are generally effective for tax years beginning on or after January 1, 2014, and may be adopted in earlier years under certain circumstances. Proposed regulations were also released that revise the rules for dispositions of tangible property and general asset accounts. The proposed regulations addressing dispositions and general asset accounts are also expected, when finalized, to be effective for tax years starting on or after January 1, 2014, and may be adopted in earlier years under certain circumstances. Based upon preliminary analysis of the final and proposed regulations, the Company expects the regulations will not have a material impact on its operations, financial position, or cash flows.

Although the Company has set up a valuation allowance against the majority of its U.S. federal and state deferred tax assets, which include net operating loss carry forwards and other losses, such allowance does not preclude the Company from using the deferred tax assets in the future. However, the Company’s ability to utilize the losses to offset future taxable income may be deferred or limited significantly if the Company were to experience an “ownership change” as defined in section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). In general, an ownership change will occur if there is a cumulative increase in ownership of the Company’s stock by “5-percent shareholders” (as defined in the Code) that exceeds 50 percentage points over a rolling three-year period. The Company determined that no ownership change has occurred for purposes of Section 382 as of December 31, 2013.

As of December 31, 2013, the liability for income taxes associated with uncertain tax benefits was $11,851,000 and can be reduced by $2,773,000 of offsetting tax benefits associated with the correlative effects of potential transfer pricing adjustments, which was recorded as a long-term income tax receivable, as well as $6,496,000 of deferred taxes. The net amount of $2,582,000, if recognized, would affect the Company’s financial statements and favorably affect the Company’s effective income tax rate.

The Company does expect changes to the unrecognized tax benefits in the next 12 months; however, the Company does not expect the changes to have a material impact on its results of operations or its financial position.

The Company recognizes interest and/or penalties related to income tax matters in income tax expense. For the years ended December 31, 2013, 2012 and 2011, the Company recognized tax expense of approximately $229,000, $44,000 and $242,000, respectively, related to interest and penalties in the provision for income taxes. As of December 31, 2013 and 2012, the gross amount of accrued interest and penalties included in income taxes payable in the accompanying consolidated balance sheets was $1,163,000 and $934,000, respectively.

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company is generally no longer subject to income tax examinations by tax authorities in its major jurisdictions as follows:



Major Tax Jurisdiction	Years No Longer Subject to Audit
U.S. federal	2008 and prior
California (U.S.)	2008 and prior
Canada	2007 and prior
Japan	2007 and prior
South Korea	2008 and prior
United Kingdom	2009 and prior

As of December 31, 2013, the Company did not provide for United States income taxes or foreign withholding taxes on a cumulative total of $109,437,000 of undistributed earnings from certain non-U.S. subsidiaries that will be permanently reinvested outside the United States. Upon remittance, certain foreign countries impose withholding taxes that are then available, subject to certain limitations, for use as credits against the Company’s U.S. tax liability, if any. If the foreign earnings were remitted, the Company does not anticipate any federal or state income taxes due to the valuation allowance against the Company’s U.S. deferred tax assets offset. The Company estimates that it would have withholding taxes of $1,200,000 upon remittance.
