“…The theoretical review of opportunistic discretionary choice research in the case of goodwill impairment provides evidence that the most common statistically significant incentives (reasons) for impairment of goodwill are: management tenure (Beatty & Weber, 2006;Ramanna & Watts, 2011) or changes of management (Guler, 2006;Masters-Stout, Costigan & Lovata, 2008;Zang, 2008), management's compensation system (Guler, 2006;Beatty & Weber, 2006;Ramanna & Watts, 2011), restrictive debt covenants (Beatty & Weber, 2006;Ramanna & Watts, 2011) or proportion of debt financing (Zang, 2008;Godfrey & Koh, 2009), and unexpectedly high (Segal, 2003;Van de Poel, Maijoor & Vanstelen, 2009) or unexpectedly low income (Guler, 2006;Cowan, Dilla & Jeffrey, 2006;Van de Poel et al, 2009;Maijoor & Vanstraelen, 2006). Incentives for the opportunistic impairment of goodwill are supported by the rules in accounting standards that allow opportunism.…”
