Investment in Dalea Investment Group, LLC

Investment in Dalea Investment Group, LLC

In June 2012, we cancelled an $11 million note receivable in exchange for a 7.66% non-controlling membership interest in Dalea Investment Group, LLC (“Dalea”), an international oilfield services company formed in March 2012.  Since the membership interests in Dalea are privately-held and are not traded in an active market, our investment in Dalea is carried at cost of $11 million.  As of March 31, 2013, we have performed a qualitative assessment and determined there has been no indication of any impairment of our investment in Dalea.
