Auditing firms consider a variety and multitude of factors when deciding whether or not to accept both a new audit client and retain an existing one. Which of the following choices would represent a situation where an auditor might choose to not accept a client? The client appears to have a robust and effective accounting system, with a newly installed system of internal controls. The client shows a record of strong profitability and operating cash flows, and has done so for many years. The client's firm has a history of financial statement restatements. The firm has a clearly defined and properly adhered to hierarchy and reporting structure.
