[1] Rent expense as presented here includes $9.5 million and $0.0 million in fiscal 2019 and 2018, respectively, 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.
