[1] Amounts for the three months ended March 31, 2019 were impacted by the adoption of ASC Topic 842 and the resulting change in the classification of certain of the Company’s leases

[2] Includes amortization of debt issue costs.

[3] Includes interest income, foreign currency exchange gain, equity in income of affiliates and interest expense - NCM and excludes distributions from NCM.

[4] Includes cash distributions received from equity investees that were recorded as a reduction of the respective investment balances (see Notes 8 and 9). These distributions are reported entirely within the U.S. operating segment.

[5] The adoption of ASC Topic 842 impacted how the Company amortizes lease related assets and liabilities such as deferred lease expenses, favorable and unfavorable lease intangible assets, long-term prepaid rents and deferred lease incentives. Beginning January 1, 2019, these items are amortized to facility lease expense for theatre operating leases and utilities and other for equipment operating leases.
