An Empirical Study on Accounting Policy Choice of Assets Impairment;

The strategy of asset impairment has become the implement of manipulating management performance, prettifying financial status, eluding market supervision for public companies.

Based on the analysis of asset impairment accounting policy of deficit public companies,we found that items mainly used in the earnings management are allowance for doubtful debts,allowance for inventory market value diminution,allowance for value diminution of fixed assets,allowance for long-term investment loss,and so on.

From providing allowance for bad debt on accounts receivable in the early 1990s in China,to promulgating the new accounting standards which require that impairment allowance should be provided for all asset items in 2006,the accounting standard about asset impairment has undergone great changes,which have caused a direct impact on the accounting information.
