At December 31, 2023 and 2022, approximately 54% and 52%, respectively, of the Company’s gross accounts receivable related to casino receivables. </span></div>Accounts receivable are typically non-interest bearing and are initially recorded at cost. Accounts are written off when management deems the account to be uncollectible. Recoveries of accounts previously written off are recorded when received. An estimated loss reserve is maintained to reduce the Company’s receivables to their net carrying amount, which approximates fair value. The loss reserve is estimated based on both a specific review of customer accounts as well as historical collection experience and current and expected future economic and business conditions. Management believes that as of December 31, 2023, no significant concentrations of credit risk existed for which a loss reserve had not already been recorded.
