A CPA has been engaged to audit the financial statements of Sapphire Distributors, Inc., a continuing audit client, for the year ended September 30, 20X8. After obtaining an understanding of Sapphire's internal control system, the CPA set control risk at the maximum level for all financial statement assertions concerning investments.
