CY2018	us-gaap	Description Of New Accounting Pronouncements Not Yet Adopted DescriptionOfNewAccountingPronouncementsNotYetAdopted	Accounting Pronouncements Not Yet Adopted<span style="font-family:Arial;font-size:10pt;">In February 2016, the FASB issued ASU 2016-02, impacting the accounting for leases, intending to increase transparency and comparability of organizations by requiring balance sheet presentation of leased assets and increased financial statement disclosure of leasing arrangements. The revised standard will require entities to recognize a liability for their lease obligations and a corresponding asset representing the right to use the underlying asset over the lease term. Lease obligations are to be measured at the present value of lease payments and accounted for using the effective interest method. The accounting for the leased asset will differ slightly depending on whether the agreement is deemed to be a financing or operating lease. For finance leases, the leased asset is depreciated on a straight-line basis and recorded separately from the interest expense in the Statements of Operations, resulting in higher expense in the earlier part of the lease term. For operating leases, the depreciation and interest expense components are combined, recognized evenly over the term of the lease, and presented as a reduction to operating income. The ASU requires that assets and liabilities be presented or disclosed separately and classified appropriately as current and noncurrent. The ASU further requires additional disclosure of certain qualitative and quantitative information related to lease agreements. The ASU is effective for the Company beginning in the first quarter 2019. Upon adoption on January 1, 2019, we expect the right-of-use asset and corresponding lease liability to approximate </span><span style="font-family:Arial;font-size:10pt;"><span>$85</span></span>. However, the Company does not expect the adoption to have a material impact to its Consolidated Statements of Operations or Consolidated Statements of Cash Flows.
