Income Taxes	11. Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, repeal of the corporate alternative minimum tax, repeal of the deduction for domestic production activities, and limitation on the deductibility of certain executive compensation. In accordance with U.S. GAAP as determined by ASC 740, Income Taxes, the Company is required to record the effects of tax law changes in the period enacted. As the Company has an April 30 fiscal year end, its U.S. federal corporate income tax rate will be blended in fiscal 2018, resulting in a statutory federal rate of approximately 30.4% (8 months at 35% and 4 months at 21%), and will be 21% for subsequent fiscal years. The Company remeasured its existing deferred tax assets and liabilities at the rate the Company expects to be in effect when those deferred taxes will be realized (30.4% if in 2018 or 21% thereafter) and recorded a one-time deferred tax expense of approximately $3,100,000 during the three months ended January 27, 2018. The Company followed the guidance in SEC Staff Accounting Bulletin 118 (“SAB 118”), which provides additional clarification regarding the application of ASC Topic 740 in situations where the Company does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Tax Act for the reporting period in which the Act was enacted. SAB 118 provides for a measurement period beginning in the reporting period that includes the Act’s enactment date and ending when the Company has obtained, prepared, and analyzed the information needed in order to complete the accounting requirements but in no circumstances should the measurement period extend beyond one year from the enactment date. The $3,100,000 expense for the one-time deferred tax remeasurement is a provisional estimate of the impact of the Tax Act. In addition, the Company has estimated that it will not have an income tax payable as a result of the one-time deemed repatriation transition tax on unrepatriated foreign earnings. These amounts are considered provisional because they use estimates for which final tax computations or returns have not been completed and because estimated amounts may be impacted by future regulatory and accounting guidance if and when issued. The Company’s financial statements do not reflect the impact of certain aspects of the Tax Act as the Company did not have the necessary information available, prepared, or analyzed (including computations), or because sufficient guidance has not been issued in order to determine an actual or provisional amount for the tax effects of the Act. To date, these aspects include the new compensation related provisions under section 162(m) and the state income tax conformity to the Tax Act. For the three and nine months ended January 27, 2018, the Company recorded a provision for income taxes of $628,000 and $277,000, respectively, yielding an effective tax rate of 300.5% and 12.6%, respectively. For the three and nine months ended January 28, 2017, the Company recorded a provision (benefit) for income taxes of $1,102,000 and $(2,809,000), yielding an effective tax rate of (102.7)% and 13.6%, respectively. The variance from statutory rates for the three and nine months ended January 27, 2018 was primarily due to a $3,100,000 remeasurement charge of the Company’s deferred tax assets and liabilities and a reduction in the fiscal 2018 federal statutory rate to 30.4%, both of which are impacts of the Tax Act. In addition, during the three and nine months ended January 27, 2018 the Company recorded discrete excess tax benefits of $212,000 and $1,614,000, respectively, resulting from the vesting of restricted stock awards and exercises of stock options. The variance from statutory rates for the three and nine months ended January 28, 2017 was primarily due to federal legislation permanently reinstating the federal research and development tax credit retroactive to January 2015 during the third quarter of fiscal 2016 and the reversal of a $968,000 reserve, including the related interest, for uncertain tax positions due to the settlement of prior fiscal year audits recorded during the first quarter of fiscal 2017. The provision for income taxes for the three months ended January 28, 2017 was also impacted by a change in estimate to reduce the full year fiscal 2017 estimated income before income taxes, which decreased the estimated fiscal 2017 effective income tax rate.
