6. The best answer to Borghi’s Question 3 is:
选项：
A.Activity ratios.
B.Solvency ratios.
C.Profitability ratios.
解释：
A is correct.
An inventory write-down increases cost of sales and reduces profit and reduces the carrying value of inventory and assets. This has a negative effect on profitability and solvency ratios. However, activity ratios appear positively affected by a write-down because the asset base, whether total assets or inventory (denominator), is reduced. The numerator, sales, in total asset turnover is unchanged, and the numerator, cost of sales, in inventory turnover is increased. Thus, turnover ratios are higher and appear more favorable as the result of the write-down.
我觉得B也对，存货减少，利润下降，则equity下降，D/E会上升
