Allowance for Doubtful Accounts

The allowance for doubtful accounts (also called the allowance for credit losses or bad debt reserve) is a contra-asset account that reduces gross receivables to the amount the company actually expects to collect. Building the allowance recognizes bad debt expense in the income statement in the same periods as the related sales; later, when a specific account is deemed uncollectible, it is written off against the allowance without a second hit to earnings (unless the allowance proves too small).

US GAAP now requires the CECL model (ASC 326) for estimating the allowance: companies must reserve for expected lifetime credit losses on receivables from day one, using historical loss experience adjusted for current conditions and reasonable forecasts. In practice most trade-AR estimates still start from an aging-based matrix, historical loss rates by aging bucket (for example 0.3 percent of current, 2 percent of 31-60, 10 percent of 61-90, 40 percent of 90+), then layer on specific reserves for known problem accounts and a forward-looking adjustment for economic conditions.

For credit and AR leaders, the allowance is where their operational world meets the financial statements. The credit department's data, aging quality, roll rates, watch lists, historical recovery experience, is the raw material auditors expect behind the estimate, and sudden allowance increases are how portfolio deterioration becomes an earnings event. A well-run credit function makes the allowance boring: losses emerge roughly as reserved, and the reserve percentage tracks the observable quality of the aging.
