Prepare a substantive audit program to test accounts receivable balances and bad debts. the construction of such a program should begin with an explicit recognition of the five financial statement assertions: 1 existence or occurence, 2 completeness, 3 rights and obligations, 4 valuation or allocation, and 5 presentation and disclosure. you should derive your specific audit objectives for accounts receivable and bad debts from these assertions. your audit program should address the five financial statement assertions, as well as any weakness in the control structure that you have uncovered. in ths regard, keep in mind the six categories of control procedures, as well as the other control structure elements. you may assume that you have satisfied yourself as to any assertions not speciffically mentioned in the narrative.
