Allowance for Doubtful Accounts The Company’s accounts receivables are subject to concentrations of credit risk. The Company maintains an allowance for its doubtful accounts receivable to reflect any estimated credit losses. The allowance is established in accordance with the current expected credit loss model, which requires the estimation of expected credit losses over the contractual life of financial assets. The allowance is calculated using a forward-looking probability-weighted approach based on historical loss experience, current economic conditions, and reasonable and supportable forecasts. The Company records the allowance in “general and administrative” expense in the Consolidated Statements of Operations and Comprehensive Loss, up to the amount of revenue recognized to date for each account. Any incremental allowance is recorded as an offset to “deferred revenue” in the Consolidated Balance Sheets. Account receivables are written off and charged against the recorded allowance when the Company has exhausted collection efforts without success. Unpaid Deferred Revenue The unpaid deferred revenue that is included in trade accounts receivable is billed in accordance with the provisions of the contracts with the Company’s customers. Major Customers The following customers accounted for 10% or more of trade accounts receivable, net:
