Case1: You are auditing SAB, which has a December 31st year-end. On December 24th, the person responsible for processing receiving reports and recording the receipt of inventory became very ill and was out of the office for a week. Due to the company's small staff and the holiday season, a number of the receiving reports were not processed on a timely basis.

As an auditor, on which assertion would you place a high importance for this entity and how would you test for it?
