Note 7.

Income Taxes

The Company’s year-to-date effective income tax rate at March 31, 2017 and 2016 was 26.3% and 17.1%, respectively. The variations between the Company’s effective tax rate and the U.S. statutory rate of 35% were primarily due to the consolidation of the Company’s foreign operations, which are subject to income taxes at lower statutory rates.

U.S. GAAP clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of March 31, 2017 and June 30, 2016, the Company’s gross unrecognized income tax benefit was $6.6 million and $5.6 million, respectively. The Company has classified the uncertain tax positions as noncurrent income tax liabilities, as the amounts are not expected to be paid within one year. If recognized, $0.5 million of the gross unrecognized tax benefits at March 31, 2017 would impact the effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision on the Condensed Consolidated Statements of Earnings. The amount of accrued interest and penalties included in the gross unrecognized income tax benefit was $0.2 million and $0.1 million at March 31, 2017 and June 30, 2016, respectively. Fiscal years 2014 to 2017 remain open to examination by the United States Internal Revenue Service, fiscal years 2012 to 2017 remain open to examination by certain state jurisdictions, and fiscal years 2006 to 2017 remain open to examination by certain foreign taxing jurisdictions. The Company’s income tax returns are not currently under examination. The Company believes its income tax reserves for these tax matters are adequate.
