Theres a topic test question that asks you to solve for FCFE, and the solution uses NET fixed asset investment as a deduction. I swear in other problems I have used gross fixed assets as a deduction. Can someone please clarify if there are different times when we would use each one, and when those times would be? This always gives me trouble as it seems to change with each FCFE/FCFF problem I do. Thanks

They probably used Net Fixed Asset but added back depreciation for CapEx, which cancels out the depreciation you added back from the general FCFE formula.

they may give you Net fixed assets but you have to adjust it for depreciation so you are not double counting it
