Jenna is working on the audit of a client's accounts receivable. During the last few weeks she has conducted interviews with the accounts receivable manager, the CFO and staff working in the accounts receivable department. She has also overseen the external confirmations of accounts receivable, 30 percent of which required the recipient to respond as to whether or not the amount stated was correct. Jenna also conducted a review of subsequent cash receipts from the client's customers. She vouched a sample of accounts receivable balances back to the underlying invoices, cash receipts, and sales returns, and traced a sample of these documents to the accounts receivable ledger.
Required
(a) List the types of audit evidence gathered by Jenna and comment on the persuasiveness of each type.
(b) Link each type of evidence to the relevant accounts receivable assertions.
