(a) When the Lessor is a manufacturer or dealer, the fair value of the property at the inception of the lease will ordinarily be its normal selling price, reflecting any volume or trade discounts that may be applicable. However, the determination of fair value shall be made in light of market conditions prevailing at the time, which may indicate that the fair value of the property is less than the normal selling price and, in some instances, less than the cost of the property.
(b) When the Lessor is not a manufacturer or dealer, the fair value of the property at the inception of the lease will ordinarily be its cost, reflecting any volume or trade discounts that may be applicable. However, when there has been a significant lapse of time between the acquisition of the property by the Lessor and the inception of the lease, the determination of fair value shall be made in light of market conditions prevailing at the inception of the lease, which may indicate that the fair value of the property is greater or less than its cost or carrying amount, if different.
