During 2013, Heartland and Jasper County, Missouri ("Jasper") entered into an agreement pursuant to which Jasper agreed to issue up to an aggregate principal amount of $55.0 million of industrial revenue bonds ("Bonds") to be purchased by Heartland. As noted below, Jasper issued the bonds and used the proceeds from the Bonds to purchase manufacturing equipment from Heartland, which was then leased back to Heartland. As Heartland will become the owner of the equipment at the end of the lease term, the lease meets the requirements of a capital lease and the equipment is being recorded as property, plant, and equipment. The Company has the right and intends to set-off any obligation to make payments under the lease agreements with the proceeds due from the Bonds. As of December 31, 2015 and 2014 Jasper had issued, and Heartland had purchased, $55.0 million, of industrial revenue bonds and Jasper had purchased from, and leased back to, Heartland certain manufacturing equipment for a corresponding amount.
