Receivables [Abstract]
Credit Loss, Financial Instrument	Specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. An estimate of credit losses for the remaining customers in the aggregate is based upon historical bad debts, current customer receivable balances, age of customer receivable balances, the customers' financial condition, all of which are subject to change. Additionally, the Company’s monitoring activities now consider future reasonable and supportable forecasts of economic conditions to adjust all general reserve percentages as necessary. Balances are written-off when determined to be uncollectible.
