[1] | As discussed above at Lease Deferrals and Abatements, the Company negotiated certain lease amendments to defer and/or abate contractual payments as a result of the COVID-19 pandemic and temporary closure of theatres. In accordance with FASB Staff guidance, the Company did not recalculate lease liabilities and right of use assets for amendments that did not result in a substantial increase in the rights of the lessor or the obligations of the lessee. Contractual payment amounts for the three months ended March 31, 2021 above are prior to the impact of deferred or abated rent amounts.
