Income Taxes	13. Income Taxes The Company recorded income tax provisions of $1.7 million and $1.2 million for the three months ended December 31, 2016 and 2015, respectively, representing effective tax rates of 42.9% and 30.3%, respectively. The Company’s effective tax reflects the impact of state income taxes, permanent tax items and discrete tax benefits. The effective income tax rate for the three month periods ended December 31, 2016 and 2015 differs from the U.S. federal statutory tax rate of 35.0% primarily due to transaction costs and contingent consideration accretion associated with the Creagh Medical and NorMedix acquisitions, the domestic production manufacturing deduction and the U.S. federal research and development income tax credit , operating losses in a jurisdiction where tax benefits are offset by a valuation allowance, and discrete tax expense related to expiring stock option awards. The total amount of unrecognized tax benefits, excluding interest and penalties that, if recognized, would affect the effective tax rate is $1.2 million as of both December 31, 2016 and September 30, 2016. Currently, the Company does not expect the liability for unrecognized tax benefits to change significantly in the next 12 months with the above balances classified on the condensed consolidated balance sheets in other long-term liabilities. Interest and penalties related to unrecognized tax benefits are recorded in income tax provision. The Company files income tax returns, including returns for its subsidiaries, in the U.S. federal jurisdiction and in various state jurisdictions as well as several non-U.S. jurisdictions. Uncertain tax positions are related to tax years that remain subject to examination. The Internal Revenue Service (“IRS”) completed an examination of the Company’s U.S. income tax return for fiscal 2012 in the fourth quarter of fiscal 2014 with a payment made associated with a timing adjustment. U.S. income tax returns for years prior to fiscal 2013 are no longer subject to examination by federal tax authorities. For tax returns for state and local jurisdictions, the Company is no longer subject to examination for tax years generally before fiscal 2006. For tax returns for non-U.S. jurisdictions, the Company is no longer subject to income tax examination for years prior to 2011. Additionally, the Company has been indemnified of liability for any taxes relating to Creagh Medical and NorMedix for periods prior to the respective acquisition dates, pursuant to the terms of the related share purchase agreements. As of December 31, 2016 and September 30, 2016 there were no undistributed earnings in foreign subsidiaries.
