Oil and Gas

(1) Reflects operating revenues of our historical oil and gas reportable segment.

(2) Includes impairment charges of $35.3 million, $15.4 million and $51.0 million in 2017, 2016 and 2015, respectively, due to the deterioration of economic conditions in the natural gas market in western Canada, partially offset by a gain related to our restructure of our future pipeline obligations. Additionally, this line item includes a charge of $16.5 million related to the settlement of litigation during 2017 associated with our previously owned Ramshorn International properties.

Rig Technologies

(3) Reflects an impairment charge for a note receivable of $3.1 million remaining from the sale of one of our former Canada subsidiaries that provided logistics services.
