[1] In the second fiscal quarter of 2016, the Company adopted updated accounting guidance on the presentation of deferred income taxes. This adoption required that deferred tax liabilities and assets be classified as noncurrent in the Consolidated Balance Sheet. The Company elected to account for this change in presentation prospectively and prior periods were not retroactively adjusted.
