A higher mix of earnings from our foreign operations, primarily in Ireland, which are taxed at lower rates than our U.S. operations and a discrete tax benefit related to share-based payment awards due to the application of ASU No. 2016-09 decreased our effective income tax rates for both periods, when compared to the prior year periods. A nontaxable gain on the bargain purchase relating to the acquisition of the critical care division of Argon also decreased the effective income tax rate for the six-month period ended June 30, 2017, when compared to the corresponding period of 2016.
