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 accretion of the liability and amortization of the related asset is recognized over the estimated mine lives for each location.
The following represents a rollforward of our asset retirement obligation liability related to our active mining locations for the nine months ended SeptemberÌý30, 2014 and for the year ended DecemberÌý31, 2013:

Represents a 12-month rollforward of our asset retirement obligation at December 31, 2013.
The revisions in estimated cash flows recorded during the nine months ended September 30, 2014 primarily were a result of the announced Empire mine extension during the first quarter of 2014. As a result of the extension, a portion of the required storm water management systems are now expected to be implemented prior to closure of the mine.
