Analysis of Bad Debts
Allowance for doubtful accounts receivable (bad debts) is a contra account which reduce the balance of the company's gross accounts receivable.The relationship between the allowance and the balance in receivables should be relatively constant unless there is a change in the economy overall or a change in customer base.
Accounts receivable primarily consist of amounts due from credit card companies from the sale of passenger airline tickets, customers of Delta's aircraft maintenance and cargo transportation services and other companies for the purchase of mileage credits under the frequent flyer program (the "SkyMiles program"). Delta provides an allowance for uncollectible accounts equal to the estimated losses expected to be incurred based on historical chargebacks, write-offs, bankruptcies and other specific analyses.
