TPSL made up a portion of our Refined Products and Renewables segment. The divested assets include (i) TPSL Terminaling Services Agreement with TransMontaigne Partners LP, including the exclusive rights to utilize </span><span style="font-family:inherit;font-size:10pt;"><span>19</span></span><span style="font-family:inherit;font-size:10pt;"> terminals; (ii) line space along Colonial and Plantation Pipelines; (iii) </span><span style="font-family:inherit;font-size:10pt;"><span>two</span></span><span style="font-family:inherit;font-size:10pt;"> wholly-owned refined products terminals in Georgia that we acquired in January 2019 and multiple third-party throughput agreements; and (iv) all associated customer contracts, inventory and other working capital associated with the assets. In December 2019, the Partnership formalized a plan and received approval to divest of its gas blending business in the southeastern and eastern regions of the United States (“Gas Blending”) and its refined products marketing business in the mid-continent region of the United States (“Mid-Con”). The Partnership had determined that these businesses were no longer core to the Partnership’s strategy. These transactions represent a strategic shift in our operations and will have a significant effect on our operations and financial results going forward. Accordingly, the results of operations and cash flows related to TPSL, Mid-Con and Gas Blending have been classified as discontinued operations for all periods presented, and prior periods have been retrospectively adjusted in the consolidated statements of operations and consolidated statements of cash flows. In addition, the assets and liabilities related to TPSL and certain assets and liabilities, particularly inventory, derivatives and leases, related to Mid-Con and Gas Blending have been classified as held for sale in our March 31, 2019 and 2018 consolidated balance sheets. On January 3, 2020, we completed the sale of Mid-Con to a third-party.

The Retail Propane businesses subject to this transaction consisted of our operations across the Mid-Continent and Western portions of the United States. On July 10, 2018, we completed the sale of virtually all of our remaining Retail Propane segment to Superior Plus Corp. (“Superior”) for total consideration of </span><span style="font-family:inherit;font-size:10pt;"><span>$889.8 million</span></span><span style="font-family:inherit;font-size:10pt;"> in cash. We retained our </span><span style="font-family:inherit;font-size:10pt;"><span>50%</span></span><span style="font-family:inherit;font-size:10pt;"> ownership interest in Victory Propane, LLC (“Victory Propane”), which we subsequently sold on August 14, 2018 (see </span><span style="font-weight:normal;">Note 2</span><span style="font-family:inherit;font-size:10pt;">). These transactions represent a strategic shift in our operations and will have a significant effect on our operations and financial results going forward. Accordingly, the results of operations and cash flows related to our former Retail Propane segment (including equity in earnings of Victory Propane) have been classified as discontinued operations for all periods presented and prior periods have been retrospectively adjusted in the consolidated statements of operations and consolidated statements of cash flows. In addition, the assets and liabilities related to our former Retail Propane segment have been </span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">classified as held for sale within our March 31, 2018 consolidated balance sheet. See </span><span style="font-weight:normal;">Note 17</span><span style="font-family:inherit;font-size:10pt;"> for a further discussion of the transaction.</span></div>
