(1) The comparability of our December 31, 2013 and 2012 quarterly results to other quarters presented were affected by a $12.9 million and $14.0 million, respectively, decrease in the ARLP Partnership’s workers’ compensation liability, excluding discount rate changes, due to the completion of its annual actuarial study, which reflected a favorable development in the ARLP Partnership’s disability emergence patterns and claims estimates (Note 17).

(2) During the quarter ended September 30, 2012, the ARLP Partnership recorded a $19.0 million impairment of the carrying value of assets at the Pontiki mine (Note 4).
