概要	Goodwill arising from acquisitions is recognized as an intangible fixed asset of the acquiring company. Companies that prepare their financial statements by International Financial Reporting Standards (IFRS) must conduct regular impairment tests on the goodwill they hold. These impairment tests examine whether the recoverable amount expected to be derived from the acquired business exceeds the carrying amount of the related goodwill. If the recoverable amount falls below the carrying amount, the company's management must recognize an impairment loss for the shortfall. When estimating the recoverable amount of the acquired business, the discounted cash flow (DCF) method is often used. In applying this method, management establishes key parameters such as projected future cash flows, discount rates, and growth rates. In other words, determining the recoverable amount relies heavily on management’s discretionary judgment. As a result, management could exercise discretion over the timing and recognition of goodwill impairments. In this study, we propose a theoretical model for evaluating the risk of goodwill impairment from the perspective of external stakeholders. We also provide a theoretical explanation of the mechanisms by which management’s discretion over recognizing and disclosing goodwill impairments arises. Furthermore, we analyze several actual cases of goodwill impairment using our proposed theoretical model.
