FOX's Pretax Income Was $0.703 Bil in the Dec 2017 Quarter, Down a Staggering 49% From Its $1.385 Bil of Pretax Income Earned in Its Dec 2016 Quarter ....................................................................................... On the Other Hand, FOX's Bottom Line After-Tax Net Income Was $1.921 Bil in the Dec 2017 Quarter, Up a Blistering 105%, or Up $0.984 Bil From Its $0.937 Bil of Bottom Line After-Tax Net Income Earned in Its Dec 2016 Quarter ....................................................................................... How Could That Be? FOX's Pretax Income Down 49%, But Its Net Income Up 105%? .......................................................................................
