解説
問 17
Incorrectア
(Beginning inventory amount + Ending inventory amount) ÷ 2 is the formula for the average inventory amount itself, which is used as the denominator; it is not the turnover ratio (= Sales ÷ Average inventory amount). It is only one component of the ratio and by itself cannot serve as an indicator of efficiency.
Incorrectイ
Sales ÷ Total assets is the total asset turnover ratio, a different indicator that measures how efficiently all assets generate sales. Because its denominator is total assets rather than inventory, it is not the inventory turnover ratio.
- ウ
正解 The inventory turnover ratio is an indicator of how many times the average inventory is turned over by the sales of a given period; its formula is Sales ÷ Average inventory amount. Because sales is in the numerator and average inventory amount in the denominator, selling more goods with less inventory makes the value larger. A higher value means a shorter period from purchasing to selling and more efficient inventory management, which matches the description in the stem. Therefore ウ is correct.
Incorrectエ
Average inventory amount ÷ Sales is the reciprocal of ウ. It reflects not how many times inventory turned over but the period needed to sell off the inventory (the inventory turnover period). The higher this value, the more inventory stagnates and the lower the efficiency, which is the opposite of the stem's statement that a higher value means greater efficiency.
ここがポイント
- Inventory turnover ratio = Sales ÷ Average inventory amount. The larger the value, the faster inventory sells and the more efficient the inventory management.
- Do not confuse these: changing the denominator to total assets gives the total asset turnover ratio, and swapping the numerator and denominator gives an indicator on the inventory turnover period side.
