2. Leases— The Company has operating leases for warehouses, manufacturing facilities, offices, cars, railcars and certain equipment. On January 1, 2019, the Company adopted the accounting and adoption guidance in ASC 842 for its operating leases resulting in the recognition of operating lease right-of-use (ROU) assets and lease liabilities on the effective date. The Company measures ROU assets throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. The lease liabilities are measured at the present value of the unpaid lease payments at the lease commencement date. Leases that include both lease and non-lease components are accounted for as a single lease component for each asset class.

The minimum payments under operating leases are recognized on a straight-line basis over the lease term in the consolidated statements of operations. Operating lease expenses related to variable lease payments are recognized in cost of sales or as operating expenses in a manner consistent with the nature of the underlying lease and as the events, activities, or circumstances in the lease agreement occur. Leases with a term of less than 12 months are not recognized on the condensed consolidated balance sheets and the related lease expenses are recognized in the condensed consolidated statements of operations on a straight-line basis over the lease term.

The accounting for leases requires management to exercise judgment and make estimates in determining the applicable discount rate, lease term and payments due under a lease. Most of our leases do not provide an implicit interest rate nor is it available to us from our lessors. As an alternative, we use our estimated incremental borrowing rate, which is derived from information available at the lease commencement date, including publicly available data, in determining the present value of lease payments. We also estimated the fair value of the lease and non-lease components for some of our warehouse leases based on market data and cost data.

The lease term includes the non-cancellable period of the lease plus any additional periods covered by either an option to extend (or not terminate) that the Company is reasonably certain to exercise. The Company has leases with a lease term ranging from 1 year to 15 years. Lease payments are generally comprised of fixed payments including in- substance fixed payments, payments that depend on an index or rate.

The operating leases of the Company do not contain major restrictions or covenants such as those relating to dividends or additional financial obligations. Finance leases are immaterial to the consolidated financial statements. There were no lease transactions with related parties as of March 31, 2019.

The operating lease expense for the three months ended March 31, 2019 was $1,227. Lease expenses related to variable lease payments and short term leases were immaterial. Other information related to operating leases follows:
