Borrowing costs

Hi My Dear Tutor,I have another question.Thanks for explaining first posting relating to interest earned on investment income

1st example)

On October 1 2015 Dawes commenced construction of a manufacturing plant that is expected to take four years to complete.It is being financed entirely by a four-year term loan of $5 million (taken out at the start of the construction).The loan carries fixed interest at 14% per annum and issue costs of 2% (of the loan value) were incurred on the loan .During the year $72000 had been earned from the temporary investment of these borrowings.

solution
interest on $5 million at 14%—————–700000
Amortisation of issue costs using straight-line apportionment(10000/4)—–25000
less interest earned on temporary investment of surplus funds————-(72000)
amount capitalised————————————————————-653000

2nd example

Apex issued a $10 million unsecured loan with a coupon (nominal) interest rate of 6% on 1 april 2016.The loan is redeemable at a premium which means the loan has an effective finance cost of 7.5% per annum.The loan specifically issued to finance the building of the new store which meets the definition of a qualifying asset in IAS23.Construction of the store commenced on 1 may 2016 and it was completed and ready for use on 28 February 2017,but did not open for trading untill 1 april 2017.During the year trading at Apex’s other stores was below expectations so Apex suspended the construction of the new store for a two month period during July and august 2016.The proceeds of the loan were temporarily invested for the month of April 2016 and earned interest of $40000

-capitalised borrowing cost
10*7.5%*8/12=50

P/l
40-earned interest
(25)-interest cost

Borrowing cost include.

1)Interest on bank overdrafts and short-term or long term borrowing
2) Interests expense using effective interest method include:
Amortization of discounts or premiums related to borrowings
Amortization of any directly attributable costs related to borrowings
Amortization of ancillary costs incurred in connection with the arrangement of borrowings.

My question here is that in the first example fixed interest rate of 14% taken but in the second example there is also fixed interest rate of 6 % but effective interest rate of 7.5% has been taken.coming to standard’s sayings about interest expense using effective interest rate is understandable for the second example.

Why 14% fixed interest taken in the first example?if 14% taken from the first example why 6%fixed interest rate has not been taken instead 7.5% taken?
