Allowance for Doubtful Accounts

The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s outstanding trade accounts receivable. The Company determines the allowance based on historical write-off experience and current information. The Company reviews its allowance for doubtful accounts each reporting period. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.

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.
