In the case of IMB, the lessor's exposure in such a case described in Paragraph CA-3.5.10 would not be significant, as the option to purchase can be exercised by making a payment of a token amount and the lessee would have no reason to refrain from exercising it. Moreover, the residual value of the asset in the lessor's book at the term of a full payout of the IMB (i.e. its residual value as assumed in fixing the lease rentals) would be zero or close to zero.
