15.	INCOME TAXES:

The Company is subject to income taxes in both United States and foreign jurisdictions. The effective income tax rate was (173.4)% and (340.7)%, respectively, for the three and six months ended June 30, 2015. The Company's effective tax rate rose significantly as the inventory write-down primarily relates to UDC Ireland Limited, which expects to incur a loss for the full year 2015 and such loss has not been tax benefited as UDC Ireland Limited has a history of losses resulting in a full valuation allowance. For the three and six months ended June 30, 2015, income tax expense of $7.5 million and $8.1 million, respectively, was recorded primarily related to foreign tax withheld on royalty and license fees paid to the Company and federal income taxes.

The effective income tax rate was 29.6% and 31.8%, respectively, for the three and six months ended June 30, 2014. For the three and six months ended June 30, 2014, an income tax expense of $8.6 million and $11.4 million, respectively, was recorded primarily related to foreign tax withheld on royalty and license fees paid to the Company and federal income taxes.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent on the Company's ability to generate future taxable income to obtain benefit from the reversal of temporary differences, net operating loss carryforwards and tax credits. As part of its assessment management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies. At this time there is no evidence to release the valuation allowances that relate to UDC Ireland, foreign tax credits and New Jersey research and development credits.
