This is a reprint of another question that I had problems posting:
My question deals with Question 5.c on page 102 of the FSA book:
co. A used the purchase method and co. B used the pool method. This question asks you to calculate the Cash Flow difference.
My logic is that the cash flow would INCREASE for the purchase method. Why? Because:
CashFlow = (S - C - D)*(1-TR%) + D
And CashFlow *ALWAYS* increase with D. Solve and simplify the equation yourself using test variables (i.e. S=$10, C=$1, TR=33.333% —> this equation simplifies to CashFlow = 6 + Dep./3 —> the cashflow always increase with depreciation!
However, the answer in the back of the book says the exact opposite. It reads that “Cash flow is unaffected.”
Did AIMR screw up?
