This study estimates the corporate tax savings from financial derivatives. I document a 3.6 and 4.4 percentage point reduction in three-year current and cash effective tax rates (ETRs), respectively, after a firm initiates a derivatives program. The decline in cash ETR equates to 10.69 million in tax savings for the average firm and 4.0 billion for the entire sample of 375 new derivatives users. Of these amounts, 8.75 million and 3.3 billion, respectively, are incremental to tax savings that theory suggests are a byproduct of risk management. Collectively, these findings provide economic insight into the prevalence of derivatives-based tax avoidance.

We investigate whether and how the complexity of derivatives influences analysts׳ earnings forecast properties. Using a difference-in-differences design, we find that, relative to a matched control sample of non-users, analysts׳ earnings forecasts for new derivatives users are less accurate and more dispersed after derivatives initiation. These results do not appear to be driven by the economic complexity of derivatives, but rather the financial reporting of such economic complexity. Overall, despite their financial expertise, analysts routinely misjudge the earnings implications of firms׳ derivatives activity. However, we find evidence that a series of derivatives accounting standards has helped analysts improve their forecasts over time.
