NOTE 14 –COMMITMENTS AND CONTINGENCIES

Environmental Remediation Liabilities

We record a liability for environmental remediation when such liability becomes probable and the costs or damages can be reasonably estimated. We accrue environmental remediation costs, on an undiscounted basis, associated with identified sites where an assessment has indicated that cleanup costs are probable and can be reasonably estimated, but the timing of such payments is not fixed and determinable. Such accruals are based on currently available information, estimated timing of remedial actions, existing technology, and enacted laws and regulations. The liability for environmental remediation is included on the Consolidated Balance Sheets in current liabilities within Accrued liabilities and in noncurrent liabilities with Other liabilities.

At December 31, 2016 and 2015, the total environmental remediation liabilities recorded were $30.9 million and $30.8 million of which $2.4 million and $2.1 million were presented in Accrued liabilities on the Consolidated Balance Sheets, respectively. We project costs over approximately 30 years.
