[1] The Company’s largest customer represents 28% of total Revenues for the three months ended March 31, 2022 (2021 — 31%). No single customer comprises more than 10% of the Company’s total Accounts Receivable as of March 31, 2022 and December 31, 2021.

[2] The revenue from this segment includes the initial upfront payments and the present value of fixed minimum payments from sale and sales-type lease arrangements of IMAX Theater Systems, as well as the present value of estimated variable consideration from sales of IMAX Theater Systems. To a lesser extent, the revenue from this segment also includes finance income associated with these revenue streams.

[3] The revenue from this segment principally includes after-market sales of IMAX Theater System parts and 3D glasses.

[4] All Other includes the results from IMAX Enhanced and other ancillary activities. In the first quarter of 2022, the Company's internal reporting was updated to reclassify the results of IMAX Enhanced out of the New Business Initiatives segment into All Other for segment reporting purposes. Prior period comparatives have been revised to conform with the current period presentation.
