[1] For 2016, income from operations reflects non-cash goodwill and long-lived asset impairment charges of $654.1 million in the second quarter.

[3] ) For 2015, income from operations reflects non-cash lower of cost or market inventory valuation reductions of $6.5 million and $135.5 million for the first and second quarters, respectively, and increases of $225.5 million and $143.6 million for the third and fourth quarters, respectively.

[4] (1) For the year ended December 31, 2016, we recorded goodwill and long-lived asset impairment charges of $309.3 million and $344.8 million, respectively, that relate to our Cheyenne Refinery, which is included in our Refining segment.

[5] (2) HEP acquired the crude oil tanks at our Tulsa Refineries in March 2016 and acquired a newly constructed crude unit, FCCU and polymerization unit at our Woods Cross Refinery in October 2016. As a result, we have recast our 2015 and 2014 HEP segment information to include these assets and related capital expenditures and certain operating expenses that were previously presented under the Refining segment. Additionally, prior year capital expenditures related to these assets have been recast as if they were incurred by HEP versus HFC in the statement of cash flows.
