[1] The write-down of assets relates primarily to owned buildings, land and equipment of those facilities identified for closure. The assets were tested for recoverability at the time the decision to close the facilities was more likely than not to occur. Our methodology for testing the recoverability of the assets is consistent with the methodology described in the "Asset Impairment Charges" section above.
