I am not able to understand why in the module answer they have not considered the tax relief lost for the APV adjustment ?? there is a tax lost by borrowing at 2.1% rather than 5% why the examiner has not considered this in the sample answer?
The subsidy benefit is 5 – 2.1 = 2.9% and he has then multiplied this by the loan amount and by 80%. The 80% is to account for the fact that they are not saving tax of 20% on the subsidy.
