Mine Closure

Our mine closure obligations are for our four consolidated U.S. operating iron ore mines, our two Eastern Canadian operating iron ore mines, our Asia Pacific operating iron ore mine, our five operating North American coal mines and a closed operation formerly operating as LTVSMC.

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 six months ended June 30, 2013 and the year ended December 31, 2012:
