(1) Results for 2013 primarily reflect the operating results from January 1, 2013 through February 6, 2013 when ERT was sold.  There were no material results of operations for ERT during the three-month period ended June 30, 2013.

(2)  Net interest expense of $2.7 millionfor the six-month period ended June 30, 2013, and $6.8 million and $14.0 million for the three- and six-month periods ended June 30,2012, respectively, was allocated to ERT primarily based on interest associated with indebtedness directly attributed to the substantial oil and gas acquisition made in 2006.  This includes interest related to debt required to be paid upon the disposition of ERT.
