Income taxes The Company’s effective tax rate on its income before income taxes from continuing operations was 46.7% in the second quarter of fiscal 2017 as compared with 9.7% in the second quarter of fiscal 2016. During the second quarter of fiscal 2017, the Company’s effective tax rate was unfavorably impacted primarily by (i) net increases to valuation allowances against deferred tax assets created primarily from acquisition related expenses that were deemed unrealizable and (ii) the impact of non-deductible acquisition related expenses, partially offset by (iii) the mix of income in lower tax jurisdictions. During the second quarter of fiscal 2016, the Company’s effective tax rate was favorably impacted primarily by (i) the mix of income in lower tax jurisdictions, (ii) the release of valuation allowances against deferred tax assets that were deemed to be realizable and (iii) the release of reserves related to audit settlements and the expiration of statutes of limitation. For the first six months of fiscal 2017 and 2016, the Company’s effective tax rate was 33.0% and 18.4%, respectively. The effective tax rate for the first six months of fiscal 2017 was unfavorably impacted primarily by (i) net increases to valuation allowances against deferred tax assets that were deemed unrealizable and (ii) the impact of non-deductible acquisition related expenses, partially offset by (iii) the mix of income in lower tax jurisdictions.

The Company applies the guidance in ASC 740, which requires management to use its judgment for the appropriate weighting of all available evidence when assessing the need for the establishment or the release of valuation allowances. As part of this analysis, the Company examines all available evidence on a jurisdiction by jurisdiction basis and weighs the positive and negative evidence when determining the need for full or partial valuation allowances. The evidence considered for each jurisdiction includes, among other items: (i) the historic levels of income or losses over a range of time periods, which may extend beyond the most recent three fiscal years depending upon the historical volatility of income in an individual jurisdiction; (ii) expectations and risks associated with underlying estimates of future taxable income, including considering the historical trend of down-cycles in the semiconductor and related industries; (iii) jurisdictional specific limitations on the utilization of deferred tax assets including when such assets expire; and (iv) prudent and feasible tax planning strategies. The Company continues to evaluate the need for the valuation allowances against its deferred tax assets and will adjust valuation allowances as appropriate, which, if adjusted, could result in a significant decrease or increase to the effective tax rate in the period of the adjustment.
