Asset Impairment Charges [Abstract]

Potential Impairments

POTENTIAL IMPAIRMENTS

We continue to review certain operations and investments for potential impairments. We currently believe we have adequate support for the carrying value of each of these operations and investments based upon the anticipated cash flows that result from estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures.

We also review from time to time possible dispositions of various assets in light of current and anticipated economic and industry conditions, its strategic plan and other relevant circumstances. Because a determination to dispose of particular assets can require management to make assumptions regarding the transaction structure of the disposition and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.
