감사인 교체기업의 보수할인 및 감사투입시간 -감사보수 자율화 이후를 기준으로-

Auditors will compete among themselves in order to win over the initial year audit engagement by significantly cutting down the audit fee, and the audit fee discount may cause the auditors to spend insufficient amount of hours on the audit engagement, which could threaten the quality of the audit. The purpose of this study is to examine the effect of audit fee discount and audit hour on auditor change, including before and after, numbers and style on auditor change. For this purpose, this study is used the difference between actual audit fee(audit hour) and adequate audit fee(audit hour). The analysis revealed four main findings: First, the audit fee discount on auditor change companies is bigger than unchanged auditor's, but the result on audit hour is different from expectation to decrease the audit hour by the audit fee discount. That is, the audit hour on auditor change companies is more than unchanged auditor's. Second, the audit fee discount of the change year is bigger than before, but the audit hour on the change year and after is more than before. Third, the audit fee discount on numbers of auditor change is significant in first auditor change companies, but the actual audit hour is more than the adequate hour in these companies. However, it is not significant difference between actual audit fee(audit hour) and adequate audit fee(audit hour) in more than second auditor change companies. Fourth, according to the result of audit fee discount and audit hour on auditor change style, the audit fee discount of NBIG4 as initial auditor is bigger than BIG4 as initial auditor, and the audit hour is more in BIG4 as pre-auditor than NBIG4 as pre-auditor without regard to an initial auditor. These results makes contribution to closely examine for discounting of audit fee and relation between audit fee discount and audit hour on auditor change.
