measures the tax effects that are incremental to those that result from tax function convexity and a reduction in taxable income volatility. I use the reported estimates of these coefficients to compute average firm-level and sample-level tax savings. I also estimate the maximum amount of firm-level and sample-level tax savings using the untabulated lower (most negative) bound of the 95 percent confidence interval for these coefficients. To calculate firm-level (sample-level) tax savings, I multiply the coefficient estimate or its lower bound by the average (aggregate) three-year sum of pre-tax book income less special items for New
