This study develops and tests a theoretical model that identifies factors contributing to DAB. Budget emphasis, leadership behavior structure and consideration, and effectiveness of audit review were examined as antecedents of attitudes toward DAB. The findings produced consistent evidence in support of the theoretical model. It is not an emphasis on meeting budgets that leads to undesirable behavior, but contextual variables, such as leadership behavior structure and effectiveness of audit review.展开更多

The study finds that for companies which experienced financial distress, the audit reports are not similar, despite all companies are similarly troubled financially. Companies receive either a disclaimer or an emphasis of matter (EOM) report. The study finds that which of the two reports is given is associated with three variables: current-year operating loss, shareholders' deficit, and default status, implying that audit reports do convey information that financial distress is not of the same level and severity among PN 17 companies.展开更多
