This paper studies the impact of quarterly earnings guidance cessation on information asymmetry using a large sample of firms during the years 2002-11. After earnings guidance cessation, information asymmetry may increase because less information is provided to the market. Alternatively, information asymmetry may decrease if managers have less pressure to manage reported earnings to meet guidance numbers. Our study shows guidance cessation significantly reduces information asymmetry compared to matched non-guiders and guidance maintainers. We also find that firms engage in less earnings management after guidance cessation, especially for firms that had provided guidance on a persistent basis.

This study examines the effect of directors' and officers' liability (D&O) insurance on firm value. Previous studies are divided on the value implication of D&O insurance: some argue for various benefits of being covered by D&O insurance, whereas others focus on the managerial opportunism stemming from being insured. In order to address whether D&O insurance increases firm value, we utilize a sample of quoted Korean companies from a period in which the disclosure of D&O insurance information was mandatory and there was a significant cross‐sectional variation in the firms' coverage of D&O insurance. We find that controlling for the endogeneity of D&O insurance coverage, D&O insurance increases firm value compared to noninsured firms. We also find evidence that the increase in firm value is pronounced for firms with greater growth opportunities, which suggests that D&O insurance can help firms to better convert growth opportunities into higher firm value.
