Leases We are obligated under capital leases covering vehicles and certain equipment. The vehicle and equipment leases generally have initial terms ranging from four to six years. Total assets relating to capital leases were approximately $58.7 million and $63.4 million as of December 31, 2018 and 2017, respectively, and a total of approximately $32.0 million and $26.8 million were fully depreciated as of December 31, 2018 and 2017, respectively. The net book value of assets under capital leases was approximately $9.5 million and $13.0 million as of December 31, 2018 and 2017, respectively. Amortization of assets held under capital leases is included within cost of sales on the Consolidated Statements of Operations and Comprehensive Income. We also have several noncancellable operating leases, primarily for buildings, improvements, equipment and certain vehicles. These leases generally contain renewal options for periods ranging from one to five years and require us to pay all executory costs such as property taxes, maintenance and insurance. Future minimum lease payments under noncancellable operating leases (with initial or remaining lease terms in excess of one year) and future minimum capital lease payments as of December 31, 2018 are as follows (in thousands):

Other Commitments and Contingencies From time to time, various claims and litigation are asserted or commenced against us principally arising from contractual matters and personnel and employment disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. As litigation is subject to inherent uncertainties, we cannot be certain that we will prevail in these matters. However, we do not believe that the ultimate outcome of any pending matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows. During the year ended December 31, 2018, we entered into an agreement with one of our suppliers to purchase a portion of the insulation materials we utilize across our business. This agreement is effective January 1, 2019 through December 31, 2021 with a purchase obligation of $16.4 million for 2019, $21.4 million for 2020 and $15.0 million for 2021. Additionally, we entered into an agreement with a chemical supplier with a purchase obligation of $0.6 million in 2019.
