The 2015 write-down of $313.3 million ($276.5 million net of tax) was due to a $224.5 million impairment of the Palmarejo complex ($193.5 million net of tax) and a $66.7 million impairment of the San Bartolomé mine, and a $22.1 million impairment ($16.3 million net of tax) of certain Coeur Capital assets, including the Endeavor silver stream and other royalties. The non-cash impairment charges were largely driven by significant decreases in long-term metal price assumptions and revised mine plans in the fourth quarter. For purposes of this evaluation, estimates of future cash flows of the individual reporting units were used to determine fair value. The estimated cash flows were derived from life-of-mine plans, developed using long-term pricing reflective of the current price environment and management’s projections for operating costs.

The 2014 write-down of $1,472.7 million ($1,021.8 million net of tax) was primarily due to a $784.0 million impairment of the Palmarejo complex ($504.5 million net of tax) and a $372.5 million impairment of the La Preciosa project ($244.9 million net of tax) due to a decrease in the Company's long-term silver and gold price assumptions reflective of the current silver and gold price environment and revised mine plans.

The 2013 write-down of $773.0 million was primarily due to a $642.1 million impairment of the Palmarejo complex ($462.3 million net of tax) and a $130.7 million impairment of the Kensington mine due to a decrease in the Company's long-term silver and gold price assumptions reflective of the current silver and gold price environment.
