2013 AM Q6 Part B

Why do they calculate the multiplicative return like this:

required spending = 6% inflation = 3.5% management fee = 0.4%

Required nominal return = (1 + 0.06 + 0.035) * (1 + 0.004) - 1 = 9.94%

They add the inflation?

Why not do this:

Required nominal return = (1 + 0.06) * (1+ 0.035) * (1 + 0.004) - 1 = 10.15%

please check the answer key

Therefore: Nominal return requirement = (1 + 0.06) x (1 + 0.004) x (1 + 0.035) – 1 = 10.15% (multiplicative method) OR Nominal return requirement = 6.0% + 0.4% + 3.5% = 9.9% (additive method) OR Nominal return requirement = (1 + 0.06 + 0.035) x 1.004 – 1 = 9.94% (calculation method, reflecting exact timing of cash flows)

All 3 methods are accepted …

^ true. overlooked my answer. thanks

ashamed by 1,000th post was so stupid
