Lease obligations. The Company has operating leases for office space and other property and equipment. The Company incurred rental expense of $7.2 million, $5.0 million and $3.0 million for the years ended December 31, 2015, 2014 and 2013, respectively, included in general and administrative expenses on its Consolidated Statement of Operations.

Drilling contracts. As a result of its lowered 2015 capital expenditure program, the Company elected to early terminate certain drilling rig contracts and recorded a rig termination expense of $3.9 million in its Condensed Consolidated Statement of Operations for the year ended December 31, 2015. The Company did not elect to early terminate any drilling rig contracts during the year ended December 31, 2014 or 2013.

As of December 31, 2015, the Company had certain drilling rig contracts with initial terms of one year or greater. In the event of early contract termination under these contracts, the Company would be committed to pay approximately $5.7 million as of December 31, 2015 for the days remaining through the end of the primary terms of the contracts.

Volume commitment agreements. As of December 31, 2015, the Company had certain agreements with an aggregate requirement to deliver or transport a minimum quantity of approximately 35.0 MMBbl of crude oil, 23.0 MMBbl of natural gas liquids and 223.0 Bcf of natural gas, prior to any applicable volume credits, within specified timeframes, all of which are ten years or less. The estimable future commitments under these agreements are $448.4 million as of December 31, 2015. The future commitment under certain agreements cannot be estimated as it is based on fixed differentials relative to WTI under the agreements as compared to the differential relative to WTI for the Williston Basin for the production month.

Purchase agreements. As of December 31, 2015, the Company had certain agreements for the purchase of fresh water with an aggregate future commitment of approximately $42.4 million.

Litigation. The Company is party to various legal and/or regulatory proceedings from time to time arising in the ordinary course of business. While the ultimate outcome and impact to the Company cannot be predicted with certainty, the Company believes that all such matters are without merit and involve amounts which, if resolved unfavorably, either individually or in the aggregate, will not have a material adverse effect on its financial condition, results of operations or cash flows. When the Company determines that a loss is probable of occurring and is reasonably estimable, the Company accrues an undiscounted liability for such contingencies based on its best estimate using information available at the time. The Company discloses contingencies where an adverse outcome may be material, or in the judgment of management, the matter should otherwise be disclosed.

On July 6, 2013, a freight train operated by Montreal, Maine and Atlantic Railway (“MMA”) carrying crude oil (the “Train”) derailed in Lac-Mégantic, Quebec. In March 2014, Oasis Petroleum Inc. and Oasis Petroleum LLC (“OP LLC”) were added to a group of over fifty named defendants, including other crude oil producers as well as the Canadian Pacific Railway, MMA and certain of its affiliates, owners and transloaders of the crude oil carried by the Train, several lessors of tank cars, and the Attorney General of Canada, in a motion filed in the Quebec Superior Court to authorize a class-action lawsuit seeking economic, compensatory and punitive damages, as well as costs for claims arising out of the derailment of the Train (Yannick Gagne, etc., et al. v. Rail World, Inc., etc., et al., Case No. 48006000001132) (the “Class-Action”). The motion generally alleges wrongful death and negligence in the failure to provide for the proper and safe transportation of crude oil.

The Company believes that all claims against Oasis Petroleum Inc. and OP LLC in connection with the derailment of the Train in Lac-Mégantic, Quebec are without merit.

On August 7, 2013, MMA filed for bankruptcy protection in the Quebec Superior Court and the United States Bankruptcy Court in Bangor, Maine (together, the “Bankruptcy Actions”). The trustees appointed in the Bankruptcy Actions have negotiated settlement agreements with the majority of the named defendants in the Class-Action, including Oasis Petroleum Inc. and OP LLC. The Quebec Superior Court and the United States Bankruptcy Court have issued orders approving the settlement agreements which were pending before them, and such orders have become final. Pursuant to the settlement agreements, Oasis Petroleum Inc. and OP LLC agreed to contribute to the compensation fund established for those suffering losses as a result of the Lac-Megantic derailment. Such contributions were fully covered by the Company’s insurance policies. Furthermore, the settlement agreements bar future litigation against Oasis Petroleum Inc. and OP LLC in Canada and the United States arising out of the Lac-Megantic derailment.
