Commitments and Contingencies

In addition to the legal action described below, the Company is a party to other proceedings and claims incidental to its business. While many of these matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect to such proceedings and claims will not have a material adverse effect on the Company's financial position as a whole or on its liquidity, capital resources or future annual results of operations. The Company records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated.

U.S. Environmental Protection Agency ("EPA") potential enforcement action.The Company has been advised by the EPA that the agency is considering an enforcement action against the Company and may seek monetary sanctions for alleged failures to prevent emissions occurring at the Company's Fain gas plant in the West Panhandle region of Texas on five separate occasions. The Company has asserted defenses to the EPA's allegations and is in discussions with the EPA regarding these matters. Although the Company cannot predict the outcome of these discussions with any certainty, the Company believes such monetary sanctions will not exceed $45,000 for any single event, but could exceed $100,000 in the aggregate.

Obligations following divestitures.In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalty obligations and income taxes. The Company does not believe these obligations are probable of having a material impact on its liquidity, financial position or future results of operations.

Lease agreements. In June 2017, the Company entered into a 20-year operating lease for the Company's new corporate headquarters in Irving, TX. Annual base rent will be $33 million and lease payments are expected to commence in the second half of 2019 when the building is complete.
