​ The Group closely monitors the collection of its accounts receivable and records allowance for doubtful accounts against aged accounts receivable and for specifically identified non-recoverable amounts. If the economic situation and the financial condition of a customer deteriorate resulting in an impairment of the customer’s ability to make payments, additional allowances might be required. Receivable balances are written off when they are determined to be uncollectable. As of December 31, 2022, the Group was not yet required to adopt the expected credit loss model for estimating the allowance for doubtful accounts. See Note 2(dd) for additional information.
