We examine whether local political corruption affects managers' discretionary disclosures of non-GAAP earnings. Using United States Department of Justice data on the number of corruption convictions of government officials, we find that firms headquartered in more corrupt districts (1) are less likely to report non-GAAP earnings, (2) have less aggressive non-GAAP earnings disclosures, and (3) experience a significant decline in the exclusion magnitudes of non-GAAP earnings. These results are more pronounced for firms with concentrated operations in their headquarter states and are robust to controlling for demographic characteristics, employing alternative corruption and non-GAAP measures, using the instrumental variable approach, and conducting a difference-in-difference analysis based on firms' relocation. Finally, we show that as local political corruption increases, managers exclude lower levels of both recurring and non-recurring items when calculating non-GAAP earnings. Overall, the results suggest that managing non-GAAP reporting is one channel through which firms could deter rent-seeking by corrupt officials.

This study examines the impact of local corruption on firms' narrative research and development (R&D) disclosures in the United States. We find that firms in more corrupt areas include fewer R&D sentences in their 10-K filings, and these sentences contain less numerical and forward-looking information. Our results hold across various measures of local corruption and R&D disclosures and remain robust after controlling for firms' R&D activities, implementing fixed effects, using difference-in-differences tests, and applying instrumental variable analysis. Additionally, the effects are more pronounced for firms with concentrated operations in their headquarters states and for firms whose R&D disclosures closely relate to future earnings. However, they are less pronounced for firms with CEOs politically aligned with the state's incumbent party and when the benefit of resolving market dispersion from firms' R&D disclosure is high. Overall, our findings indicate that local corruption adversely affects firms' narrative R&D disclosures.
