* in november 2015 the fasb issued amended guidance that clarifies that in a classified statement of financial position an entity shall classify deferred tax liabilities and assets as noncurrent amounts .
this guidance superseded asc 740-10-45-5 which required the valuation allowance for a particular tax jurisdiction be allocated between current and noncurrent deferred tax assets for that tax jurisdiction on a pro rata basis .
we elected to early adopt the standard retrospectively in fiscal 2016 which resulted in the reclassification of current deferred income tax assets to non-current deferred income tax assets and non-current deferred income tax liabilities on our consolidated balance sheets for fiscal 2017 2016 and 2015 .
