[1] The Company’s largest customer represents 17% and 15%, respectively, of total Revenues for the three and six months ended June 30, 2022 (2021 — 20% and 25%, respectively). No single customer comprises more than 10% of the Company’s total Accounts Receivable as of June 30, 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.
