What are the current controls(based on above situational facts) that needs to be tested by IA during the audit?

Here's the following situation and facts: 1. For frequent travellers (over night trips), the company will provide a credit card (CC) with a credit limit of $5,000 for use only on business travel and related expenses; no personal purchases are allowed. A credit crad request form is completed by the traveller, and approved by cost center (CC) Mer and forwarded to Accounting for processing. The credit card will be in the name of the employee (ie employee is responsible for paying off all balances at the end of each month, which is due by the 15th of each following month). However, the company can be held liable in case of non-payment. Accounting will send notice to traveller, cost center (CC) Mgr & Controller of balances past due of 30 days or more. 2. The company has implemented an online airline reservation system that provides real-time routing options and prices. Travellers can access this system, using their employee id & password, to view the various options and book their airline reservations. All booked air travel are charged to the traveller's credit card. Last year airline expenses totaled $22 million (budget was $19 million). 3. The Purchasing Dept had negotiated a corporate agreement last year with Avis for rental cars and Marriott for hotels with preferred rates. If Avis or Marriott properties are not available at travel locale, employees are allowed to choose other suppliers. 4. Accounting has developed an Excel template file that includes days of the week, place of travel, business purpose and categories for each expense item (air, hotel, meals, etc). The T & E reports can be filed on a weekly basis. The traveller will attach the receipts (required for any individual item > $20) to a hard copy of the T & E template report and forward to Accounting for review and reimbursement. 5. An annual budget, including T & E items, are established at the beginning of the fiscal year, and the Budget Dept provides monthly spending analysis to each CC Mgr.
