We investigates firm’s quantitative and qualitative supplement of human resource in internal accounting control after disclosing internal control weakness. Samples are 124 listed firm-years that disclosed internal control weakness on audit report from 2006 to 2009(here after, IACW firms). This study uses two proxies to measure the level of human resource in internal accounting control. One is the ratio of the number of employees involved in internal accounting controls to the total number of employees of the firm(hereafter, NUM), the other is the ratio of the weight-averaged career of employees involved in internal accounting controls to the total number of employees of the firm(hereafter, EXP). We find that only NUM is significantly higher at the next year after than disclosure of internal accounting control weakness. We also find similar result using 84 firm-years that are improved internal accounting control weakness at the next year after weakness disclosure, which indicates that most IACW firms increase their investment in human resource in internal accounting control irrespective of y/n of internal accounting control weakness improvement. This investment makes 68% of IACW firms to improve the internal accounting control weakness. These findings provide insight into the role of human resource investment to improve the internal accounting control weakness. Not only that, these findings are able to strengthen the results of prior researches that examined the voluntary effort to improve internal accounting control weakness.
