CFAI Mock Exam (AM) Qn 50 - FCFF already, 130, someone, change

Ionutzakis

When calculating the change in FCInv, the answer sheet adds back depreciation ($61):
(1,203 ? 1,130) + 61 = –134
Can someone explain the intuition behind this? I don’t get it since $61 is already added via Non-cash charges.

You’re not adding depreciation twice, you’re just trying to find the change in gross PPE so that you can find WCINV
