Leases [Abstract] |
Leases of Lessee Disclosure [Text Block] | Leases We adopted ASC Topic 842 on September 1, 2019, using the modified retrospective approach. In addition, we used the additional optional transition method and package of practical expedients in the period of adoption without retrospective adjustment to previous periods presented, although we elected not to apply the hindsight practical expedient. As a result of using the additional optional transition method and following a modified retrospective approach, prior periods have not been restated, and a $33.7 million cumulative-effect adjustment was recorded to increase the opening balance of capital reserves as of the adoption date related to recognition of previously deferred gains associated with the sale-leaseback of our primary corporate office building located in Inver Grove Heights, Minnesota. Our accounting for finance leases (previously referred to as capital leases) remains substantially unchanged; however, adoption of ASC Topic 842 resulted in recognition of operating lease right of use assets and associated lease liabilities of $268.4 million and $267.0 million, respectively, as of September 1, 2019. Adoption of ASC Topic 842 did not have a material impact on our Condensed Consolidated Statements of Operations or Condensed Consolidated Statements of Cash Flows. We assess arrangements at inception to determine whether they contain a lease. An arrangement is considered to contain a lease if it conveys the right to control the use of an asset for a period of time in exchange for consideration. The right to control the use of an asset must include both (a) the right to obtain substantially all economic benefits associated with an identified asset and (b) the right to direct how and for what purpose the identified asset is used. Certain arrangements provide us with the right to use an identified asset; however, most of these arrangements are not considered to represent a lease as we do not control how and for what purpose the identified asset is used. For example, our supply agreements, warehousing and distribution services agreements, and transportation services agreements generally do not contain leases. We lease property, plant and equipment used in our operations primarily under operating lease agreements and, to a lesser extent, under finance lease agreements. Our operating leases are primarily for railcars, equipment, vehicles and office space, many of which contain renewal options and escalation clauses. Renewal options are included as part of the right of use asset and liability when it is reasonably certain that we will exercise the renewal option; however, renewal options are generally not included as we are not reasonably certain to exercise such options. Operating lease right of use assets and liabilities for operating leases are recognized at the lease commencement date for leases in excess of 12 months based on the present value of lease payments over the lease term. For measurement and classification of lease agreements, lease and nonlease components are grouped into a single lease component for all asset classes. Variable lease payments are excluded from measurement of right of use assets and liabilities and generally include payments for nonlease components such as maintenance costs, payments for leased assets beyond their noncancelable lease term and payments for other nonlease components such as sales tax. The discount rate used to calculate present value is our collateralized incremental borrowing rate or, if available, the rate implicit in the lease. The incremental borrowing rate is determined for each lease based primarily on its lease term. Certain lease arrangements include rental payments adjusted annually based on changes in an inflation index. Our lease arrangements generally do not contain residual value guarantees or material restrictive covenants. Lease expense is recognized on a straight-line basis over the lease term. The components of lease expense recognized in our Condensed Consolidated Statements of Operations are as follows:
