[1] Catalyst leases are valued using a market approach based upon commodity prices for similar instruments quoted in active markets and are categorized as a Level 2 measurement. The Company has elected the fair value option for accounting for its catalyst lease repurchase obligations as the Company’s liability is directly impacted by the change in fair value of the underlying catalyst. During 2018, Toledo Refining and Chalmette Refining entered into two platinum bridge leases which were settled in April 2019 and Delaware City Refining entered into a new platinum bridge lease, which will expire in the second quarter of 2019. These leases are payable at maturity and are not anticipated to be renewed. The total outstanding balance related to these bridge leases as of March 31, 2019 and December 31, 2018 was $2.5 million and $2.4 million, respectively, and is included in Current debt in the Company’s Condensed Consolidated Balance Sheets.
