(a) If a consumer lease is terminated early and the lessee is not in default and does not exercise a purchase option or if the lessee’s liability at the scheduled end of the lease term is based upon the vehicle’s residual value and the lessee does not exercise a purchase option, the holder shall act in a commercially reasonable manner when disposing of the vehicle or obtaining cash bids for the purpose of establishing the realized value of the vehicle. The realized value shall be final and binding upon the parties and shall be used as the realized value in determining the lessee’s liability at early termination or at the scheduled end of the lease term. Nothing in this Section shall be deemed to prohibit the lessee and the lessor from agreeing upon the vehicle’s realized value or the method of determining the vehicle’s realized value, in which case the value agreed upon shall be final and binding upon the parties and shall be used as the realized value in determining the lessee’s liability at early termination or at the scheduled end of the lease term.
     (b) In the event of a total loss of the vehicle prior to the end of the lease term occasioned by its theft, physical damage, or other occurrence as specified in the consumer lease, the realized value will be deemed to be the sum of the amount received by the holder from the lessee’s insurance company or from any other party in payment of the loss and the amount received by the holder of the lessee’s deductible under the lessee’s insurance policy.
