NOTE 12 - ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS
The following is a summary of our environmental and mine closure obligations:
Mine Closure
The accrued closure obligation for our active mining operations provides for contractual and legal obligations associated with the eventual closure of the mining operations. The closure date for each of our active operating mine sites was determined based on the exhaustion date of the remaining iron ore reserves. The closure date and expected timing of the capital requirements to meet our obligations for our indefinitely idled or closed mines is determined based on the unique circumstances of each property. For indefinitely idled or closed mines, the accretion of the liability is recognized over the anticipated timing of remediation. The amortization of the related asset and accretion of the liability is recognized over the estimated mine lives for our active operations.
The following represents a roll forward of our mine closure obligation liability for the three months ended March 31, 2019 and for the year ended December 31, 2018:
