(7) Trade Accounts Receivable 

Trade Accounts Receivable

Trade accounts receivables are recorded at the contractual or invoiced amount.

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, 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.
