대손충당금 분류조정을 이용한 상호저축은행의 이익관리; 특별대손충당금을 중심으로

This study examines earnings management method of savings banks which serve as representative financing institution for people with poor credit. Because regulatory and supervisory regulations of savings banks are different to those of commercial banks, managers of savings banks may reflect these characteristics in earnings management method. Especially, managers of the savings bank are expected to choose the earnings management method considering resulting costs and benefits such as effects on BIS ratio, discretion of loan assets classification, and the magnitude of earnings management. Empirical evidence indicates that savings bank discretionarily exploit classification of loans assets to smooth earnings. Specifically, managers discretionarily classify loan assets items upwards or downwards within non-performing assets. In addition, savings banks with BIS ratio lower than 7% tend to manage earnings upwards by classifying loan assets items upwards within non-performing assets to increase both net income and BIS ratio. The results of study imply that limitation of present regulatory and supervisory rules on savings banks incurs unintended negative effects on agency problem
