Seattle, WA-Based Boeing's 4Q 2017 Revenues Up 9% From the 4Q 2016, Operating Income Up 39%, Pretax Income Up 41% and Net Income Up a Much Higher 92% ....................................................................................... That 92% Net Income Growth Was Buoyed By a Reduction in 4Q 2017 Income Tax Expense of $1.051 Bil Due To the Trump Tax Bill, Primarily the Tax Debt Forgiveness Feature in It ...................................................................................... Absent the Effect of the Trump Tax Bill, Boeing's 4Q 2017 Net Income Would Have Increased By 28% Rather Than the Reported 92% Increase
