Restricted Cash

At December 31, 2019, 2018 and 2017, the company did not have any restricted cash. The restrictions on the cash acquired in February 2017, as a result of the consolidation of Merey Sweeny, were fully removed in May 2017 when Merey Sweeny’s outstanding debt that contained lender restrictions on the use of cash was paid in full. See Note 6—Business Combinations, for additional information regarding our consolidation of Merey Sweeny.
