[1] In fiscal year 2016, the Company early-adopted ASU 2015-17, "Balance Sheet Classification of Deferred Taxes", which requires that deferred income tax liabilities and assets be classified as noncurrent in the Consolidated Balance Sheet. As such the requirement under prior guidance which required an entity to separate deferred tax liabilities and assets into a current and non-current amount in the Consolidated Balance Sheet has been eliminated. The prior periods have not been retroactively adjusted as a result of the adoption of ASU 2015-17.
