Answer:
Under IFRS, net defined benefit liability is reported in balance sheet when Present value of defined benefit obligation (PVDBO) exceeds Fair value of plan assets(FVPA) which results in deficits.
In this case, PVDBO exceeds FVPA, then the difference betwen the two ix the net defined benefit liability.
Difference of PVDBO and FVPA = $38,000,000 - $30,000,000 = $8,000,000. Hence, net defined benefit liability reported in the balance sheet is $8,000,000.
