SEGMENTS

As described in Note 1, our businesses are organized based on the nature and location of the services they provide. Certain summarized information related to our reportable segments is shown in the tables below. None of the operating segments have been aggregated. The results of HFOTCO, subsequent to the acquisition date, are shown as a separate segment below. Although Corporate and Other does not represent an operating segment, it is included in the tables below to reconcile segment information to that of the consolidated Company. Prior period segment disclosures have been recast to include the SemMexico and SemLogistics segments within Corporate and Other, as these businesses are no longer significant and are not expected to be significant in the future. Eliminations of transactions between segments are also included within Corporate and Other in the tables below.

During the fourth quarter of 2017, we changed our definition of segment profit to focus on the results of each segment exclusive of general and administrative costs and related overhead allocations. Segment Profit is defined as revenue, less cost of products sold (exclusive of depreciation and amortization) and operating expenses, plus equity earnings and is adjusted to remove unrealized gains and losses on commodity derivatives and to reflect equity earnings on an EBITDA basis. Reflecting equity earnings on an EBITDA basis is achieved by adjusting equity earnings to exclude our percentage of interest, taxes, depreciation and amortization from equity earnings for operated equity method investees. For our investment in NGL Energy, we exclude equity earnings and include cash distributions received. Prior period segment profit has been recast to be consistent with the revised definition.

The accounting policies of each segment are the same as the accounting policies of the consolidated Company. Transactions between segments are generally recorded based on prices negotiated between the segments.

Our results by segment are presented in the tables below (in thousands):
