Commitments and Contingencies Related to Discontinued Operations
Discontinued operations represent former mining activities, the last of which ended in 2002. Pursuant to an agreement with the United States Environmental Protection Agency (the “EPA”), the Company performed certain remediation actions at a property sold over fifty years ago. This remediation work was completed by September 30, 2015. The Company has established a contingency provision related to discontinued operations, which was $498,000 and $522,000, as of September 30, 2018 and December 31, 2017, respectively. No change to the provision was required for either of the three and nine month periods ended September 30, 2018 and 2017.
The remaining balance of the accrued remediation costs as of September 30, 2018 mainly represents estimated future charges for EPA response costs, monitoring of the property, and legal costs. The total costs to be incurred in future periods may vary from this estimate. The amounts recorded in the aforementioned contingency provision are not discounted. The provision will be reviewed periodically based upon facts and circumstances available at the time.
