Illustrative Audit Case: Keystone Computers \& Networks Inc. Part IV: Consideration of Internal Control This part of the audit case of Keystone Computers \& Networks Inc. (KCN) illustrates the nature of internal control over the acquisition cycle and the way in which auditors assess control risk for this cycle. The following working papers are included: - A flowchart description of the acquisition cycle of the company and the related controls prepared by the staff of Adams, Barnes \& CO. (ABC), CPAs. This flowchart focuses on the (accounting) information system and control activities. - ABC's working paper for the assessment of control risk for accounts payable and purchases as it would appear before any tests of controls are performed. This working paper identifies the prescribed controls and weaknesses for the revenue cycle. It also relates the controls and weaknesses to the various financial statement assertions about accounts payable and purchases. You should read through the information to obtain an understanding of typical controls for this cycle. You also may wish to review the planning documentation presented in Appendix 6C to refresh your knowledge about the nature of the company's business and its environment. The Control Environment, Risk Assessment, Monitoring Questionnaire, and Organizational Chart of KCN in Appendix 11A can be used to help refresh your memory about these components of internal control.
