New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which will require lessees to recognize leases on their balance sheets as a right-of-use asset with a corresponding liability. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of 12 months or less. Additional qualitative and quantitative disclosures, including significant judgments made by management, will also be required. The Company will adopt the standard (as well as amendments issued related to Topic 842 since February 2016) effective beginning January 1, 2019, using the cumulative-effect adjustment transition method. In addition, the Company plans to elect the package of practical expedients permitted under the transition guidance, which among other things, allows the Company to carry forward the historical lease classification. In addition, the Company plans to make an accounting policy election to not recognize an asset and liability for leases with an initial term of 12 months or less. Those lease payments will be recognized in the consolidated statement of operations on a straight-line basis over the lease term. In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842), Land Easement Practical Expedient for Transition to Topic 842, which permits an entity to make an election not to apply Topic 842 to land easements that existed or expired before the effective date of Topic 842 provided that they were not previously assessed under ASC 840, Leases. Effective January 1, 2019, Topic 842 will be applied to new and modified land easements to determine whether the arrangement should be accounted for as a lease. Upon the Company's adoption of Topic 842, the Company intends to apply this guidance by making an election to not apply Topic 842 to its land easements that existed or expired before January 1, 2019. The Company estimates the adoption of Topic 842 will result in the recognition of additional right-of-use assets and lease liabilities in the Company's consolidated balance sheet as a result of operating leases currently not recognized on the balance sheet of not more than 8% of the Company's total asset. No material cumulative-effect adjustments are expected. The Company does not believe the standard will materially impact its operating results or liquidity or have an impact on its debt covenant compliance under its current agreements.
