Resource Management and Other Commercial Events

Divestitures

In January 2014, the Company sold a non-strategic exploration tenement asset in Australia in exchange for cash proceeds of $62.6 million.  The Company had previously recorded an impairment charge in December 2013 to write down the carrying value of that asset to its fair value. Accordingly, there was no gain or loss recognized on the disposal during the three months ended March 31, 2014.

Subsequent Event

During April 2014, the Company finalized pricing under a sales agreement for one of its Western U.S. Mining segment customers. As a result of that agreement, the Company will recognize additional contract revenue totaling $33.5 million in the second quarter of 2014 and higher realized prices through the remainder of 2014.
