Payroll Data Co. (PDC) processes payroll transactions for a retailer. Cook, CPA, is engaged to express an opinion on management's description of PDC's system and suitability of the design of controls. PDC's system is relevant to the retailer's internal control, so Cook's report may be useful in providing the retailer's independent auditor with information necessary to plan a financial statement audit. Cook's report should:
A. contain a disclaimer of opinion on the operating effectiveness of PDC's controls.
B. identify the controls that were tested to obtain reasonable assurance that PDC's controls were operating effectively.
C. identify PDC's controls relevant to specific financial statement assertions.
D. disclose Cook's assessed level of control risk for PDC.
