[1] | During fiscal 2015 and 2014, we recorded net tax benefits of $0.9 million and $1.4 million, respectively. We recorded a benefit of $0.5 million in the first quarter of fiscal 2015 resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of income tax reserves due to the expiration of the statute of limitations 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 2015, we recorded a tax benefit of $0.4 million primarily due to the reversal of reserves for state research and development tax credits and transfer pricing, partially offset by an adjustment of the state rate on net deferred tax assets. We recorded net tax benefits of $0.2 million in the first quarter of fiscal 2014 resulting from the release of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions. During the second quarter of fiscal 2014, we recorded a tax benefit of $1.1 million resulting from re-measurement and reversal of certain income tax reserves as a result of the conclusion of a federal income tax audit for fiscal 2012. In the third quarter of fiscal 2014, we recorded a tax benefit of $0.1 million primarily for a valuation allowance reversal associated with the reassessment of state research and development tax credits.
[2] | During fiscal 2015, we recorded a gain of $1.4 million from the settlement of a property and casualty insurance claim related to the replacement of our capital equipment destroyed in the fire at our subcontract manufacturer's location. We recorded $1.0 million ($0.6 million after tax) during the second quarter of fiscal 2015 and $0.4 million ($0.3 million after tax) during the third quarter of fiscal 2015.
[3] | In the second quarter of fiscal 2015, we recorded a business restructuring accrual of $0.5 million ($0.3 million after tax).
