Leases Leases
On January 1, 2019, we adopted the guidance under ASU No. 2016-02, "Leases" ("ASC 842") under the cumulative-effect method of transition where comparative information has not been restated and continues to be reported under the standards in effect for those periods. The adoption did not result in any cumulative-effect adjustment to beginning retained earnings. We elected certain practical expedients upon adoption and therefore has not reassessed whether any expired or existing contracts contain leases, has not reassessed the lease classification for any expired or existing leases and has not reassessed initial direct costs for any existing leases.
Our leases principally consist of operating leases related to our corporate office, field offices, and our research, manufacturing and storage facilities. Our lease terms do not include options to extend or terminate the lease until we are reasonably certain that we will exercise that option.
At inception, we determined if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of our lease arrangements contain lease components (e.g. minimum rent payments) and non-lease components (e.g. maintenance, labor charges, etc.). We account for each component separately based on the estimated standalone price of each component.
Operating leases are included in Right-of-use assets, Lease obligations, current and Lease obligations, long term on the Consolidated Balance Sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term using an incremental borrowing rate consistent with the lease terms or implicit rates, when readily determinable. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet.
Lease expense for operating leases, which principally consists of fixed payments for base rent, is recognized on a straight-line basis over the lease term. Lease expense for the years ended December 31, 2020 and 2019 was $740,577 and $744,781, respectively.
    Supplemental information related to leases for the year ended December 31, 2020 was as follows:
Cash paid for amounts included in the measurement of operating lease liabilities $ 650,194 
Right-of-use assets obtained in exchange for new operating lease liabilities $ 2,772,072 
Weighted-average remaining lease term - operating leases 3.3 years
Weighted-average discount rate - operating leases %

Future minimum lease commitments under non-cancellable operating leases as of December 31, 2020 were as follows:
