Credit Loss [Abstract] |
ALLOWANCE FOR DOUBTFUL ACCOUNTS | ALLOWANCE FOR DOUBTFUL ACCOUNTS Accounts receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time accounts receivable are past due, previous loss history, current and expected economic conditions and the specific customer's current and expected ability to pay its obligation. Accounts receivable are considered past due when they are outstanding longer than the contractual payment terms. Accounts receivable are written off when management deems them uncollectible. A reconciliation of the beginning and ending balances of the allowance for doubtful accounts is as follows (in thousands):
