은행업의 대손충당금적립 기준변경에 따른 정보유용성에 관한 연구

Abstract

The loan loss provision standard has been changed to the incurred loss model since the introduction of K－IFRS in 2011 and the expected loss model again from 2018. In the banking business, loan receivables account for more than 70% of total assets, so the change in the provision for bad debt has a great impact on capital and net income. First, this study compared and analyzed the stock price explanatory power of the disclosure of net income after adjustment and net income due to the change in the standard for loan loss provision for loan receivables for the banking business. As a result of the analysis, there was no significant difference in share price explanatory power between capital and net income before and after the reflection of the bad debt reserve. In other words, information users did not reflect the difference between net income before credit loss reserves and post－adjusted net income in the stock price. Second, when analyzed by dividing into the period for applying the incurred loss model and the period for applying the expected loss model, the explanatory power in the incurred loss model period was less than the entire period. And explanatory power increased significantly during the expected loss model period than during the entire period. This means that the capital and net income of the expected loss model period are more useful information to explain the stock price than the capital and net income of the incurred loss model period. In addition, the explanatory power of the adjusted net income was greater during the incurred loss model period, but there was no difference in the explanatory power of the stock price before and after the credit loss reserve was reflected during the application period of the expected loss model. This means that the bad debt reserve information is more useful in the incurred loss model than in the expected loss model.
