Free Cash flow

good morning! i have reproduced a cashflow statement given in a question (bpp). we are supposed to value of the company using free cashflow for the next 5 years. growth rates are also given. i know the mechanics but what i dont know is how to get the starting figure. of course that means i totally lack the understanding of FCF and FCFE. In the answer, it simply says "based on the X5 FCFE post reinvestment of 87.2, which represents a surrogate for the dividend that could be paid...." how does he get this figure? what does post reinvestment signify? ------------------------------------------------------------X5----------------------X4 Net cashflow from operating activities -------210-----------------------95 Return on Investment and servicing of finance Interest received------------------------12------------------------------6 interest paid------------------------------(4)-----------------------------(3) interest element in fin. leases-------(6.5)--------------------------(4) -----------------------------------------------------------1.5------------------------(1) taxation------------------------------------------------(4.1)-----------------------(0.2) Cap Ex------------------------------------------------(120.2)--------------------(75) Acquisition and Disposals Proceeds from sale of Joint ventures---------10 cash inflow before mgmt of liquid resources---------------------------------------------97.2-------------------------33.8 Management of liquid resources Dec/(inc) of short term deposits---------------35.5--------------------------(32.2) Financing Repayment of secured loan--------------------(31)----------------------------(25) inc/(dec) in cashflow for the year-------------101.7---------------------------(23.4)
