The 2016 write-down of $4.4 million ($3.9 million net of tax) was due to the impairment of Coeur Capital assets. The operator of the Endeavor mine in Australia, on which the Company holds a 100% silver stream, announced in early 2016 a significant curtailment of production due to low lead and zinc prices. As a result, Coeur recorded a $2.5 million write-down of the mineral interest associated with the Endeavor Silver Stream at March 31, 2016. In April 2016, Coeur sold its tiered NSR royalty on the El Gallo mine to the operator, a subsidiary of McEwen Mining Inc., for total consideration of approximately $6.3 million, including $1 million in contingent consideration. In anticipation of this sale, the Company recorded a $1.9 million write-down of the mineral interest at March 31, 2016.
