Accountants making judgments with respect to a particular set of standards are increasingly aware of standards from other reporting regimes that offer additional or conflicting guidance. In fact, IFRS encourages reliance on out‐of‐regime standards when IFRS lacks guidance. This paper reports the results of two experiments which provide evidence that auditors in such circumstances are vulnerable to contrast effects , whereby reporting judgments under IFRS are systematically influenced away from the accounting treatment supported by standards from another regime (U.S. GAAP ). Contrast effects are observed (i) when out‐of‐regime standards are considered before making a reporting judgment under IFRS , and (ii) when out‐of‐regime standards are applied as local GAAP for a subsidiary of a foreign parent that reports under IFRS . We also find that contrast effects are reduced when auditors believe IFRS lacks guidance. These results have implications for financial statement preparers and auditors in the current incomplete‐convergence environment.

ABSTRACT We report the results of four experiments investigating the relationship between (1) the quality of an audit, (2) jurors' assessments of the standard of prudent care (SOC) against which audit quality is compared, and (3) jurors' negligence verdicts. Experiment 1 operationalizes audit quality by varying the sample size used in audit testing, and provides evidence that jurors anchor their assessment of SOC on audit quality, producing a “competitive mediation” in which audit quality reduces the potential for a negligence verdict directly, but increases that potential indirectly by increasing SOC. Experiment 2 generalizes this finding to a setting that operationalizes audit quality by varying the size of adjustment the auditor required. Experiments 3 and 4 extend these results to a setting in which SOC is elicited after jurors make negligence verdicts. Overall, these experiments provide insight into the role of SOC in constraining and justifying negligence verdicts. Data Availability: Contact the authors.
