SEC interventions and the frequency and usefulness of non-GAAP financial measures

This paper examines the effect of two Securities and Exchange Commission regulatory interventions related to disclosure of non-GAAP financial measures. There are three main results. First, the probability of disclosure of non-GAAP earnings declines in 2003, but the probability of disclosure of other non-GAAP financial measures has an accelerated decline after the first intervention. Second, all else equal, after Regulation G, investors have a positive market reaction to the disclosure of non-GAAP earnings. Finally, investors react to the adjustments made by I/B/E/S financial analysts as they do to the GAAP surprise, but they do not react to the additional adjustments made by firms.
