[1] Certain reclassification of amounts have been made to conform with the current year presentation for comparative purposes. The results of operations, assets and liabilities for all units included in the Company's disposal plans discussed in Note 8 have been reclassified to discontinued operations in the statements of operations and balance sheets for all periods presented. Occupancy costs have been reclassified from Other operating expenses to a separate line item on the Consolidated Statement of Operations and group insurance, employer 401k matching and employee meal costs have been reclassified from Other operating expenses to Payroll and related costs to provide comparability to financial results reported by our peers in the industry.
