New York-Based Payment Technology Co First Data Had an Excellent 4Q 2017 With Revenues Up 7% From the 4Q 2016 and Pretax Income Up 33% ....................................................................................... But That Pretax Income Growth of 33% Was Peanuts in Comparison to the After-Tax Net Income Growth in the 4Q 2017 of a Blistering 299% or Up By $751 Mil Over the 4Q 2016 ....................................................................................... So What's Going On Here? Well, First Data's Income Tax Expense Was Lower By a Huge $687 Mil in the 4Q 2017 With Income Tax Expense Moving From $24 Mil in the 4Q 2016 to an Income Tax Benefit of $663 Mil in the 4Q 2017 ....................................................................................... That Huge Income Tax Expense Earnings Improvement Was Driven Primarily By a 4Q 2017 Large Income Tax Benefit Resulting From the Puzzling, Very Lucrative US Federal Income Tax Debt Forgiveness Feature in the US Trump Tax Cuts Act
