[1] | In the second quarter of fiscal 2018, the Company recorded a net tax benefit of $41,199 due to the revaluation of its net deferred tax liabilities primarily related to the lower federal corporate tax rate, partially offset by the lower federal benefit for state taxes and the change from a worldwide tax system to a territorial tax system, and a net tax benefit of $16,929 attributable to the lower effective tax rate required to bring our first half into alignment with the expected full year rate.
