Income Taxes	13. Income Taxes For interim income tax reporting, we are required to estimate our annual effective tax rate and apply it to year-to-date pretax income excluding unusual or infrequently occurring discrete items. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded. The Company recorded income tax provisions of $2.9 million and $1.9 million for the three months ended June 30, 2016 and 2015, respectively, representing effective tax rates of 41.6% and 33.0%, respectively.

The effective income tax rates for the three and nine months ended June 30, 2016 differ 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. The effective income tax rate for the three and nine months ended June 30, 2016 differs from the three and nine months ended June 30, 2015 primarily due to transaction costs, contingent consideration accretion, and foreign currency gain (losses) associated with the fiscal 2016 acquisitions.

Tax jurisdictions with losses for which tax benefits cannot be realized are excluded. The Company recorded income tax provisions of $2.9 million and $1.9 million for the three months ended June 30, 2016 and 2015, respectively, representing effective tax rates of 41.6% and 33.0%, respectively.
