10.	Income Taxes

The Company is subject to income taxes in the U.S. and various state and foreign jurisdictions. Tax statutes and regulations within each jurisdiction are subject to interpretation and require the application of significant judgment. The Company is currently under examination by three state jurisdictions for the years 2010 through 2016. The Company does not expect resolution of these examinations to have a material impact on its results of operations, financial condition or cash flows.

The Company’s total liability for unrecognized tax benefits as of March 31, 2017 and June 30, 2016 was $0.6 million and $0.4 million, respectively. The $0.6 million unrecognized tax benefit at March 31, 2017, if recognized, would impact the Company’s effective tax rate.

The effective tax rate was favorably impacted by corporate owned life insurance (COLI) gains and research and development (R&D) credits resulting in the following tax benefits. The tax expense during the three and nine months ended March 31, 2017 was positively impacted by non-taxable COLI gains of $1.2 million and $1.4 million, respectively. The tax expense was also positively impacted during the three and nine months ended March 31, 2017 by R&D tax credits of $3.9 million in 2017 for both years 2016 and 2017.
