[1] | During fiscal 2017 and 2016, we recorded net tax benefits of $1.0 million and $1.5 million, respectively. We recorded a benefit of $0.1 million in the first quarter of fiscal 2017 resulting from the reversal of income tax reserves due to the 18. QUARTERLY FINANCIAL DATA (UNAUDITED)(CONTINUED)expiration of the statutes of limitation from various U.S. and foreign tax jurisdictions. In the third quarter of fiscal 2017, we recorded a tax benefit of $0.7 million from the reversal of income tax reserves due to the expiration of the statutes of limitation from various U.S. and foreign tax jurisdictions. In the fourth quarter of fiscal 2017, we recorded a net tax benefit of $0.2 million, primarily from the reversal of income tax reserves due to the expiration of the statutes of limitation from various U.S. and foreign tax jurisdictions and state and foreign prior year true-up provision to return. We recorded a benefit of $0.7 million in the first quarter of fiscal 2016 resulting from the reinstatement of the research and development tax credit for calendar year 2015, reversal of income tax reserves due to the expiration of the statutes of limitation from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2016, we recorded a tax benefit of $0.5 million primarily due to the filing of an amended income tax return resulting in a domestic refund related to qualified manufacturing activities. In the fourth quarter of fiscal 2016, we recorded a net tax benefit of $0.2 million, primarily due to the filing of an additional amended income tax return resulting in an additional domestic refund related to qualified manufacturing activities, partially offset by an adjustment of the state rate on net deferred tax assets.
[2] | For continuing operations, we recorded business restructuring charges of $2.5 million ($1.6 million after tax) in the third quarter of fiscal 2017, $0.7 million ($0.4 million after tax) in the first quarter of fiscal 2016 and $0.1 million ($0.1 million after tax) in the second quarter of fiscal 2016.
