This paper examines shareholder wealth effects in U.S. and home-country markets relating to the Securities and Exchange Commission's (SEC) decision to eliminate the Form 20-F reconciliation. During the period of examined events, we find positive cumulative abnormal returns for the treatment sample of U.S. cross-listed firms that prepare financial statements under International Financial Reporting Standards (IFRS), but no such effects for our control sample comprising cross-listed non-IFRS, U.S. domestic, or home-country firms. We find the stock market impact for our treatment sample to be positively related to our proxy for cost savings and negatively related to the pre-adoption reconciliation magnitude from IFRS to U.S. GAAP. This suggests shareholders place some value on reconciliation information, but the costs of preparing and auditing reconciliations generally outweigh concern about information loss. Moreover, we find that information loss is less pronounced for firms having used IFRS for a longer period, suggesting the learning effect mitigates information loss.

We examine whether the December 2007 PCAOB disciplinary order against Deloitte affected Deloitte's switching risk, audit fees, and audit quality relative to the other Big 4 firms over a three-year period following the censure. Our findings suggest that the PCAOB censure was associated with a decrease in Deloitte's ability to retain clients and attract new clients, and a decrease in Deloitte's audit fee growth rates. However, methodologies used in extant archival studies yield little or no evidence to suggest that Deloitte's audit quality was different from that of the other Big 4 firms during a three-year window either before or after the censure. Overall, our results suggest that the PCAOB censure imposed actual costs on Deloitte. Data Availability: All data are publicly available.
