[1] Rent expense as presented here includes $11.6 million in the third quarter of fiscal 2019, and $24.3 million year-to-date in fiscal 2019, of operating lease rent expense related to stores within discontinued operations, but for which GAAP requires the expense to be included within continuing operations, as we expect to remain primarily obligated under these leases.
