Income Tax Disclosure [Abstract]
Income Taxes	J. Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was signed into law. The 2017 Tax Act includes a broad range of tax reform provisions affecting businesses, including lower corporate tax rates, changes in business deductions, and international tax provisions. In response to the 2017 Tax Act, the U.S. Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations where a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Tax Act. SAB 118 provides that the measurement period is complete when a company’s accounting is complete and that the measurement period shall not extend beyond one year from the enactment date. SAB 118 provides guidance for registrants under three scenarios: (i) measurement of certain income tax effects is complete, (ii) measurement of certain income tax effects can be reasonably estimated, and (iii) measurement of certain income tax effects cannot be reasonably estimated. The 2017 Tax Act lowered the federal statutory tax rate from 35% to 21%. As the Company has a fiscal year ending April 30, it is subject to a blended tax rate for the current fiscal year. Therefore, a blended rate of 29.73% was computed as the federal statutory rate for this year. The Company has analyzed the income tax effects of the 2017 Tax Act and determined that (ii) measurement of the income tax effects can be reasonably estimated, and, as such, provisional amounts have been recorded. The Company believes that all provisional amounts reflected in its financial statements are based on the best estimates that can be made at this time. The Company will continue to analyze all impacts of the 2017 Tax Act and will update provisional amounts as required. The Company recognized income tax expense of $1,566,000 and $3,149,000 for the three and nine months ended January 31, 2018. The effective tax rate is 63.0% and 44.8% for the three and nine months ended January 31, 2018. In accordance with ASC 740, ”Income Taxes”, which requires deferred taxes to be re-measured in the year of an income tax rate change, the Company recorded a provisional discrete deferred income tax expense of $587,000 in the three months ended January 31, 2018 as a result of applying a lower U.S. federal income tax rate to the Company’s net deferred tax assets. The Company revalued the U.S. deferred tax balances based on the tax rates effective for the following fiscal year at the new federal rate of 21% for amounts that are not expected to reverse during the current fiscal year and revalued the deferred tax balances expected to reverse in the current fiscal year at the Company’s current fiscal year blended rate of 29.73%. The Company has not yet completed the revaluation of the deferred tax balances due to estimates which are being used during interim periods until finalization of the balances can occur at the Company’s fiscal year end. The 2017 Tax Act also includes a one-time transition tax on accumulated unrepatriated foreign earnings. In the three months ended January 31, 2018, the Company recorded a provisional discrete current income tax expense of $528,000 on accumulated unrepatriated foreign earnings, including estimates for foreign earnings through April 30, 2018. In addition, the Company has not yet completed the calculation of the related income tax pools for its foreign subsidiaries. The Company is entitled to elect to pay the one-time transition tax over a period of eight years. The Company intends to make this election and has recorded $486,000 of the provisional expense as other non-current liabilities in the Company’s Consolidated Balance Sheet for January 31, 2018. No additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax, or any additional outside basis difference inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations. The Company is currently in the process of evaluating the new Global Intangible Low-Taxed Income (“GILTI”) provisions and has not yet elected an accounting policy with respect to whether to reflect GILTI in its deferred tax calculations or not. Therefore, the Company has not made any adjustments related to the GILTI tax in its financial statements. Under the SEC guidance noted above, the Company will continue to analyze and assess the effects of the GILTI provisions of the Act. The Company anticipates future impacts at a U.S., state and local tax level related to the 2017 Tax Act as statutory and interpretive guidance is not available from applicable tax authorities needed to reasonably estimate the impact. Consequently, the Company has not recorded provisional amounts for this statutory and interpretive guidance and have continued to apply ASC 740 based on the provisions of the tax laws that were in effect immediately prior to the 2017 Tax Act enactment.
