Historical cost: a measure of the cost of purchasing products. Generally, the value of purchased products becomes historical cost after being recorded. For example, 20 10, buying a car for 200,000 as fixed assets accounting, then 200,000 is the historical cost.

Replacement cost: the asset value is purchased at the current market price, which is applicable to the fixed assets with surplus. Of course, the market price evaluated at that time was multiplied by the new rate of the surplus assets;

Net realizable value: the ending inventory is measured according to the lower of net realizable value and cost, and net realizable value = the market price of the product corresponding to the inventory held for production-the processing cost incurred for completing the product-the related expenses incurred for selling the product;

Present value: generally used when long-term receivables are involved, and the entry value of long-term receivables is based on the present value of expected future cash flows;

Fair value: Be familiar with the price that both parties voluntarily trade, and follow the principles of fairness and openness.
