IAS23: Borrowing Costs

How much was actually borrowed from the bank on 1 January, 2016? $1.5 million So, do you agree that you would have to pay interest at 9% on $1.5 million for the full year? But you didn't need the full amount immediately so you were able to invest half of it on 1 January for 6 months So you have to pay interest at 9% on $1.5 million for the full year but you are able to earn interest at the rate of 7% on the temporary investment of $750,000 for the six months from 1 January, 2016 to 30 June, 2016 So borrowing costs capitalised will be: 9% x $1.5 million x 12/12 = $135,000 less 7% x $750,000 x 6/12 = $26,250 giving an aggregate of $108,750 and that's split $36,250 for asset A and $72,500 for asset B I assume that this agrees with BPP (hopefully!) OK?
