Leases [Abstract] |
Adoption of ASC 842 | 2. Adoption of ASC 842 On January 1, 2019, we adopted ASC 842 using the additional transition method option provided by ASU 2018-11. Under this transition method, we applied the new accounting guidance on the date of adoption. Upon adoption, a cumulative effect adjustment was not required; however, the effect of this guidance on our consolidated financial statements impacted our balance sheet presentation by increasing the amount of our noncurrent assets for the inclusion of right-of-use assets of $15.9 million and increasing the amount of our liabilities for the inclusion of the associated lease obligations of $15.9 million, most of which were classified as noncurrent. Under the transition option we elected, ASC 842 is applied only to the most current period presented in the financial statements and our reporting for the comparative periods presented in the financial statements continue to be in accordance with Topic 840, including disclosures. Upon adoption, we elected the following accounting policies or practical expedients related to ASC 842:
| • | not reassess whether any expired or existing contracts are or contain leases, not reassess the lease classification for any expired or existing leases, and not reassess initial direct costs for any existing leases;
| • | apply accounting similar to Topic 840 operating leases accounting to leases that meet the definition of short-term leases; and
| • | not evaluate land easements that exist or expired before January 1, 2019 and that were not previously accounted for as leases under Topic 840.
We determine if an arrangement is a lease at inception. Since our leases generally do not provide an implicit rate, we use our incremental borrowing rate based on the lease term and other information available at the commencement date in determining the present value of lease payments. Lease expense is recognized on a straight-line basis over the lease term. Currently, most of our leases are classified as operating leases under which we are the lessee and primarily relate to railcars, other equipment and office space. In addition, our leases that are classified as finance leases (previously classified as capital leases) and other leases under which we are the lessor are not material. Most of our leases do not include options to extend or terminate the lease prior to the end of the term. As of June 30, 2019, we did not have any material operating leases with lease terms greater than one year that have not yet commenced. 2. Adoption of ASC 842 (continued)
