ABSTRACT This study examines the relation between earnings management and block ownership of same‐industry peer firms by a common set of institutional investors (common institutional ownership). This relation is important given the tremendous growth of common institutional ownership and the significant influence of blockholders on financial reporting. We hypothesize that common institutional ownership mitigates earnings management by enhancing institutions' monitoring efficiency and by encouraging institutions to internalize the negative externality of a firm's earnings management on peer firms' investments. Consistent with our hypothesis, we find that higher common institutional ownership is related to less earnings management. Analyses of a quasi‐natural experiment based on financial institution mergers show that this negative relation is unlikely to be driven by the endogeneity of common institutional ownership. Cross‐sectional tests provide evidence that the negative relation is stronger among firms for which common institutional ownership is likely to generate a greater reduction in institutions' information acquisition and processing costs, and among firms whose severe financial misstatements are more likely to distort co‐owned peer firms' investments, supporting both mechanisms underlying our hypothesis. Our findings inform the ongoing debate on the costs and benefits of common institutional ownership by highlighting an important benefit: the enhanced monitoring of financial reporting.

ABSTRACT Cash flow hedge derivatives are an example of an economic transaction that is not fully portrayed in the financial statements in two key ways. First, while changes in the fair value of the derivative are recorded at each reporting date, changes in the value of the underlying purchase or sale commitment are not recorded or disclosed until that transaction occurs. Therefore, until the purchase or sale occurs, the financial statements only portray half of the economic transaction. Second, the gains/losses associated with these derivatives provide an inverse signal about the persistence of firm profitability. We document a method by which financial statement users can partially adjust for these distortions and find evidence that debt investors incorporate information conveyed by cash flow hedge gains/losses into their pricing of new debt issuances. We also find evidence that credit analysts incorporate these adjustments into their firm‐level credit ratings but are unable to find consistent evidence of similar adjustments to credit ratings on new debt issuances. Overall, our results suggest that a subset of sophisticated investors (i.e., those in public debt markets) appear to incorporate information from cash flow hedge accounting into their assessments of firm risk, and that users may benefit from enhanced disclosure about the amount and timing of a firm's future transactions that are exposed to foreign currency, interest rate, or commodity price risk as well as the amount and timing of derivatives that protect the firm from those risks.
