问题如下：
An analyst observes a decrease in a company’s inventory turnover. Which of the following would most likely explain this trend?
选项：
A. The company installed a new inventory management system, allowing more efficient inventory management.
B. Due to problems with obsolescent inventory last year, the company wrote off a large amount of its inventory at the beginning of the period.
C. The company installed a new inventory management system but experienced some operational difficulties resulting in duplicate orders being placed with suppliers.
解释：
C is correct.
The company’s problems with its inventory management system causing duplicate orders would likely result in a higher amount of inventory and would, therefore, result in a decrease in inventory turnover. A more efficient inventory management system and a write off of inventory at the beginning of the period would both likely decrease the average inventory for the period (the denominator of the inventory turnover ratio), thus increasing the ratio rather than decreasing it.
解析：存货周转率变低说明一年中存货周转的次数变少了，不是好事。A选项说的是公司新建了一个效率更好的存货管理系统，那应该是周转率增加才对，所以不选A。B说的是存货过时了，因此公司对存货进行了减值，也就是周转率的分母变低，那分数应该是增加才对，所以也不选B。C选项的意思是公司采用了一套新的存货管理系统，但是这个系统运行中有点问题，导致了向供应商重复下单，采购订单增加会增加存货库存，进而降低存货周转率。
inventory turnover 不等于DOH吗
