Question Bank 4.11

I am trying to work out some attribution analysis questions.

In this particular one there are 3 assets

equities, bonds (long duration) and bonds (<5 years)

Benchmark allocation (60, 40,0) respectively
Actual Allocation (80,0,20)

I have worked out the stock selection profit and the sector selection profit and the totals seem to add up to whats in the solution.

however, the question states that i need to determine the split between

1)equity and bonds (long duration)
2)bonds (long duration) and bonds(<5years)

I get the following answers

sector profit for equities = 1.52
sector profit for bonds (<5 years) = -1.48
sector profit for bonds (long) = 4.56

total = 4.6 (which is what i get and it matches to the answer)

My questions is that how can we split this to determine the %of this allocation to 1 and 2 mentioned above?

for sector selection i use the following formula -- (actual sector weight - benchmark sector weight)*(benchmark return on x - total benchmark return)

This is a question from the question bank 4.11? I am analysing only quarter 1.

The solution says
1- 3.8
2- 0.8

All calculations are correct other wise I would be able to match the total stock selection and sector selection profit.

really confused, please help.

Thanks
