﻿ I n December 2017, the Tax Cuts and Jobs Act (the “Tax Act”) became law. Among other things, the Tax Act reduced the federal corporate tax rate from 35% to 21% and allowed for full depreciation expensing of qualified property when placed in service. ﻿ As a result of the decrease in the effective tax rate, the Company recorded a decrease in its net deferred tax liabilities of $26.7 million, with a corresponding reduction to deferred income tax expense. During fiscal year 2018, the Company adopted a tax calculation method change that resulted in the accelerated deduction of certain property-related expenditures. As a result of this change and the aforementioned change in the federal corporate tax rate, the Company recorded an additional decrease in its net deferred tax liabilities of $10.6 million, with a corresponding reduction to deferred income tax expense.
