(1) The comparability of the December 31, 2015 quarterly results to other quarters presented was affected by $89.4 million of asset impairment charges relating to the Onton mine, MC Mining mine and a surrendered lease (Note 4 - Long-Lived Asset Impairments), which was partially offset by a $22.5 million net gain relating to final business combination accounting for the Hamilton Acquisition (Note 3 – Acquisitions).  An impairment charge of $10.7 million impacted the comparability of the September 30, 2015 quarterly results to other quarters presented.  The comparability of the June 30, 2014 quarterly results to other quarters presented was affected by a $7.0 million insurance settlement related to adverse geological events at the Onton mine in 2013 and a gain of $4.4 million recognized on the sale of Pontiki’s assets.
