cost of Investment

Good morning Sir

this is more of a revision question:

if there is a deferred payment of, lets say, 24m in 3 years and the cost of capital is 10%, the unwounding entries will be as follows:

PV = 24/1.1^3=18m

year 1:

Dr Finance cost —- 1.8 (18 x 10%)
Cr Def Liab ———– 1.8

year 2

Dr finance cost —- 1.98 (18 x 1.1 X 10%)
Cr Def Liab ——— 1.98

year 3

Dr finance cost —- 2.39 (18 x 1.1 x 1.1 x 1.1 x 10%)
Cr Def Liab ——— 2.39

correct?

thanks in advance
