Because of severe hurricane losses, Donaldson Decorators, one of your oldest and largest clients, suddenly and unexpectedly went bankrupt. Approximately 30% of your client's total sales have been made to Donaldson Decorators during each of the past several years. The amount due from Donaldson Decorators--none of which is collectible--equals 22% of the total accounts receivable, an amount that is considerably in excess of what was determined to be an adequate provision for doubtful accounts at the close of the previous year. Discuss how your client would record the write-off of the Donaldson Decorators receivable if it is using that allowance method of accounting. Justify your suggested treatment.
