BUSINESS SEGMENTS

The Partnership has four reportable segments: natural gas services, terminalling and storage, sulfur services and marine transportation. The Partnership’s reportable segments are strategic business units that offer different products and services. The operating income of these segments is reviewed by the chief operating decision maker to assess performance and make business decisions.

The accounting policies of the operating segments are the same as those described in Note 2 in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 16, 2018, as amended, by Amendment No. 1 on Form 10-K/A filed on March 29, 2018. The Partnership evaluates the performance of its reportable segments based on operating income. There is no allocation of administrative expenses or interest expense.
