The text says that in the opening years we apportion AIA & WDA but not the FYA. In the example why do we only apportion WDA by 9/12 and the AIA is 100%. Thank you Agata
AIA is 100%! What we apportion is how much expenditure is available for AIA. If you look at the answer you will see that the annual 500,000 limit is time apportioned to 9/12 x 500,000 = 375,000 This is more than big enough to allow all the AIA qualifying expenditure of the period to have the 100% AIA
