[1] In February 2022, the Company early terminated certain license agreements with a customer for film and television content, which was delivered in previous years, in order for the Company to use the content primarily on our DTC services (Content License Early Termination). Because the content is functional intellectual property (IP), we had recognized substantially all of the consideration to be paid by the customer under the licenses as revenue in prior years when the content was made available under the agreements. Consequently, we recorded the amounts to terminate the licenses agreements, net of remaining amounts of deferred revenue, as a reduction of revenue.
