9 . Legal Proceedings In January 2017 we exercised our right to utilize the arbitration process to review the division of revenue collected beginning May 1, 2016, as well as to clarify other issues, under our Joint Service Agreement with BNSF Railway Company (BNSF). BNSF requested the same. In October 2019 the arbitrators issued a Final Award and we recorded pretax charges in the third quarter 2019 of $26.8 million related to certain charges claimed by BNSF and $17.4 million for legal fees, cost and interest claimed by BNSF, for a total of $44.2 million. On January 17, 2020, we filed under seal in the United States District Court for the Western District of Arkansas (the Arkansas Federal Court) a motion to confirm and enforce the Final Award, seeking the Courts specific enforcement of certain confidential contractual rights the arbitrators decided in our favor. BNSF has moved to confirm the Final Award in the United States District Court for the District of Columbia. During the first quarter 2020, we recorded an $8.2 million pretax charge resulting from an adjusted calculation of the revenue divisions owed to BNSF under the Final Award. On July 21, 2020, the Arkansas Federal Court granted our motion in part, entering a judgment confirming the arbitration awards. In a sealed opinion, the Court denied our request for additional enforcement relief but did not foreclose our right to pursue post-confirmation enforcement in court or in arbitration if warranted. We have filed an appeal with the United States Court of Appeals for the Eighth Circuit seeking review of the Arkansas Federal Courts denial. In June 2019, we recorded pretax charges of $20 million for the settlement of a casualty claim within our DCS segment. We are involved in certain other claims and pending litigation arising from the normal conduct of business. Based on present knowledge of the facts and, in certain cases, opinions of outside counsel, we believe the resolution of these claims and pending litigation will not have a material adverse effect on our financial condition, results of operations or liquidity.
