Asset appraisal is a re-evaluation of the fair value of enterprise assets and liabilities on the base date. Most subjects of enterprises are cost measurement. When I bought the assets, it was a lot of money, and then it began to depreciate, which was reflected in the statement as a net value. But what is the real value of this asset now? This requires asset evaluation. Of course, each subject's assets and liabilities have their own valuation methods, and you will know it after reading the book. This is the cost method in the ordinary sense, and it is also the income method to evaluate the overall value of the enterprise by predicting the future development trend of the enterprise and the market method to obtain the enterprise value by comparing with other enterprises. Generally speaking, the fair value of the statement is evaluated, that is, the value on the base date.
