| Asset Retirement Obligation |
ASSET RETIREMENT OBLIGATION
A component of the consideration exchanged to purchase the GIGS assets in June 2015 was the assumption of the seller's asset retirement obligation ("ARO") associated with such assets. The ARO represents the estimated costs of decommissioning the GIGS pipelines and onshore oil receiving and separation facilities in Grand Isle, Louisiana at retirement. The Company recognized the ARO at its estimated fair value on the date of acquisition with a corresponding ARO asset capitalized as part of the carrying amount of the related long-lived assets to be depreciated over the assets' remaining useful lives.
The Company's tenant, EGC Tenant, has an ARO related to the platform which is currently attached to the GIGS pipelines. If in the future, EGC Tenant is unable to fulfill their obligation, the Company may be required to assume the liability for the related asset removal costs.
In periods subsequent to the initial measurement of an ARO, the Company recognizes changes in the liability resulting from (a) the passage of time through accretion expense and (b) revisions to either the timing or the amount of the estimate of undiscounted cash flows based on periodic revaluations. Future expected cash flows are based on subjective estimates and assumptions, which inherently include significant uncertainties which are beyond the Company's control. These assumptions represent Level 3 inputs in the fair value hierarchy. The Company has no assets that are legally restricted for purposes of settling asset retirement obligations.
In December 2018 and 2017, the Company revised its estimates to reflect a decrease in (i) marketplace rates for labor and other costs, (ii) for the expected timing of work and for (iii) recent decommissioning estimates. During the fourth quarter of 2018, the Company decommissioned a segment of the GIGS pipeline system. The Company incurred decommissioning costs of approximately $939 thousand compared to the estimated segment ARO liability of $628 thousand resulting in a loss on settlement of ARO of $311 thousand. The loss on settlement of ARO is recorded in general and administrative expenses in the Consolidated Statements of Income for the year ended December 31, 2018. For the year ended December 31, 2017, the change in estimate did not result in any charge to income.
The following table is a reconciliation of the asset retirement obligation as of December 31, 2018 and 2017:
