초록

본 연구에서는 기업의 신용평가등급(RANK) 변화(하락,상승)가 실물이익조정에 미치는 영향을 살펴보았다. 가설검증을 위해 2008년부터 2013년까지 한국거래소에 상장되어 있는 기업을 대상으로 총 6년 동안 기업-연도 2,583개의 표본을 사용하여 연구를 진행하였으며 실증분석한 연구결과는 다음과 같다. 첫째, 신용평가등급(RANK)과 실물이익조정의 측정치인 비정상영업현금흐름(ACFO)과 비정상재량적비용(ADE)간에는 양(+)의 관련성이 나타났으며, 비정상제조원가(AMC) 간에는 음(-)의 관련성이 나타났다. 둘째, IFRS 도입과 비정상재량적비용(ADE) 간에는 양(+)의 관련성이 나타났으며, 비정상제조원가(AMC) 간에는 음(-)의 관련성이 나타났다. 셋째, 신용평가등급(RANK)이 상승한 경우 비정상영업현금흐름(ACFO)과는 1%수준에서 유의한 양(+)의 관련성이 나타났고, 비정상재량적비용(ADE)과는 유의하지 않은 음(-)의 관련성이 나타났고, 비정상제조원가(AMC)는 10%수준에서 유의한 양(+)의 관련성이 나타났다. 넷째, 신용평가등급이 하락한 경우 비정상영업현금흐름(ACFO)과는 음(-)의 관련성이 나타났고, 비정상제조원가(AMC)와는 양(+)의 관련성이 나타나 신용평가등급이 하락한 기업은 자본조달비용을 감소시키기 위해 미래의 현금흐름을 포기하더라도 양(+)의 실물이익조정을 행하는 것으로 나타났다.
