The sales and income (loss) from operations amounts reported above include results from our Lucky Friday segment. The Lucky Friday mine is our only operation where some of our employees are subject to a collective bargaining agreement, and the most recent agreement expired on April 30, 2016. On February 19, 2017, the unionized employees voted against our contract offer. On March 13, 2017, the unionized employees went on strike and have been on strike since that time. Production at Lucky Friday was suspended from the start of the strike until July 2017, when limited production resumed. For the first nine months of 2017, suspension costs not related to production of $11.1 million, along with $3.3 million in non-cash depreciation expense, are reported in a separate line item on our unaudited condensed consolidated statement of operations. We cannot predict how long the strike will last or whether an agreement will be reached. As a result of the strike or other related events, operations at Lucky Friday could continue to be disrupted, which could adversely affect our financial condition and results of operations.
