K－IFRS 도입이 자산손상차손 지속성과 자본시장 반응에 미치는 영향

The purpose of this study is to examine the effects of IFRS adoption on the quality of asset impairment loss and capital market valuation, and to conduct empirical analysis. This study uses accruals market anomaly studies to examine both the positive and negative effects of K－IFRS adoption on earnings quality and capital markets. The results of the analysis are as follows. First, asset impairment loss and asset impairment loss by type before K－IFRS adoption were not persistent, but persistent after K－IFRS adoption. Second, as a result of analyzing the capital market response of the asset impairment using the Mishkin test, profit firms before K－IFRS adoption show that there is market anomaly in the discretionary asset impairment loss and intangible asset impairment loss, but after K－IFRS adoption did not show market anomaly due to the specificity of asset impairment accounting standards and frequent recognition of asset impairment. Loss firms before K－IFRS adoption did not show market abnormalities, but after K－IFRS adoption overestimates the persistence of impairment loss of discretionary asset, tangible asset, and goodwill. The results of this study provide evidence that K －IFRS adoption has improved the standard for impairment of intangible assets, but that the standard on impairment of tangible assets and goodwill are still insufficient. This study divides the profit－and－loss firms and classifies them by asset impairment type, and presents the empirical analysis results. This is different from the previous studies in that it confirms all asset impairment factors that have positive and negative aspects due to K－IFRS adoption. The findings of this study are expected to be useful as a basis for the improvement of the insufficient paragraphs of K－IFRS 1036, which will help to establish a more complete K－IFRS settlement.
