During a preliminary survey in planning stage of an auditing process, an auditor notes that several accounts payable vouchers for major suppliers show adjustments for duplicate payment of prior invoices. This would indicate:

Select one: a. A need for additional testing to determine related controls and the current exposure to duplicate payments made to suppliers. b. A lack of control in the receiving area that prevents timely notice to the accounts payable area that goods have been received and inspected. c. The existence of a sophisticated accounts payable system that correlates overpayments to open invoices and therefore requires no further audit concern. d. A fraudulent activity has occurred and the auditor should invite external experts to deal with this matter.

Which of the following audit procedures provides the best evidence about the collectability of notes receivable?

Select one:

a. Confirmation of note receivable balances with debtors

b. Examination of notes for appropriate debtors signatures

c. Reconciliation of the detail of notes receivable and the provision for uncollectible amounts to the general ledger control

d. Examination of cash receipts records to determine promptness of interest and principle payments
