Why do I see an Accrued Interest balance each month? (IFRS 16)

IFRS 16 requires establishing and recognizing the "Right of Use Asset" and the "Liability" for all material leases which is calculated as the present value of the remaining lease payments over the lease term. The lease liability established at the start of the lease is reduced by the rent paid in advance and the interest is then accrued on the remaining amount of the liability. The rent amount that is being paid each month is split between Principal and Interest components.
