(ii) Tin Ltd has 1,000 stock lines that are maintained on a perpetual inventory system. Stock is counted on a cyclical basis so that all lines are covered at least once per year. Raymond attended the March stocktake to observe the counting procedures and conducted 20 test counts from the floor to the client's count sheets and 20 from the client's count sheets to the floor. He uncovered two minor discrepancies of one item each, which he considered to be immaterial. The client also uncovered five minor discrepancies between the perpetual records and the actual quantity on hand. None of these discrepancies were adjusted on the perpetual records, as the amounts involved only totaled $50,000 and were considered to be immaterial. Raymond concluded that no further work was considered necessary on stock quantities at year end. Required: (a) In your own words, explain what is meant by sufficient appropriate audit evidence.
