Consider the following:

a. John Ltd's mortgage of $842 500 requires payments of $11 200 each month. During the next year the interest component of the payments will equal $61 232.

b. Frieda Ltd's mortgage of $232 200 requires payments of $60 000 over the next year. By the end of next year the principal due on the mortgage will have gone down to $189 400.

c. Graham Ltd's $87 436 mortgage requires monthly payments of $1500 plus interest. During the next year payments will total $25 674.
In each case, calculate:
1. Current liability at the end of this year

2. Noncurrent liability at the end of this year

3. Interest expense for the next year.
