For contracts that are not settled, a contract liability is created. The expected duration of the performance obligation is less than one year. The amount of revenue recognized that was included in the opening contract liability balance was $0.6 million for each of the years ended December 31, 2021 and 2020. This revenue consisted primarily of the Company’s deferred gaming revenue from player points earned through play at the Company’s casinos located in the United States.

In March 2020, the Company wrote-down its receivables related to MCE based on assessments made due to COVID-19 and future cash flows of MCE, and as a result, charged $0.3 million to general and administrative expenses during the year ended December 31, 2020. Substantially all of the Company’s contracts and contract liabilities have an original duration of one year or less. The Company applies the practical expedient for such contracts and does not consider the effects of the time value of money. Further, because of the short duration of these contracts, the Company has not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period or when the Company expects to recognize this revenue.
