16.	INCOME TAXES:

On January 1, 2017, the Company adopted ASU No. 2016-09, Improvements to Employee Share-Based Accounting, which includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. Under the previous guidance, tax effects of deductions for employee share awards in excess of compensation cost ("windfalls") were recorded in equity in the period in which the deductions actually reduced income taxes payable and any unrecognized tax benefits were tracked separately off the balance sheet. Under the new guidance, excess tax benefits and deficiencies are recorded in the income statement in the period in which stock awards vest or are settled, and any excess tax benefits not previously recognized because the related tax deduction had not reduced current taxes payable, are recorded through a cumulative-effect adjustment to retained earnings at the beginning of the period of adoption.

The Company is subject to income taxes in both the United States and foreign jurisdictions. The effective income tax rate was 23.0% and 22.3%, respectively, for the three and six months ended June 30, 2017. The tax rate reflected a benefit from the utilization of a valuation allowance at UDC Ireland. For the three and six months ended June 30, 2017 the Company recorded income tax expense of $14.1 million and $16.5 million, respectively.

Without the adoption of ASU No. 2016-09 for the three and six months ended June 30, 2017 the effective income tax rate would have been 24.2% and 24.8%, respectively, and income tax expense would have been $14.8 million and $18.4 million, respectively.

The effective income tax rate was 33.6% and 33.5%, respectively, for the three and six months ended June 30, 2016. For the three and six months ended June 30, 2016, income tax expense of $11.0 million and $12.0 million, respectively.

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 and New Jersey research and development credits.
