Leases

Effective January 1, 2019, the Company adopted the new lease accounting standard (see Recent Accounting Pronouncements in Note 1. above) using the modified retrospective method. Adoption of this standard resulted in the recording of net operating lease ROU assets and corresponding operating lease liabilities of $0.3 million with no impact to retained earnings as of January 1, 2019. Leases for reporting periods beginning on or after January 1, 2019 are presented under the new guidance, while prior periods amounts are not adjusted and continue to be reported in accordance with previous guidance.

Operating lease ROU assets are presented within Other Property and Equipment on the consolidated balance sheet as of December 31, 2019. The current portion of operating lease liabilities are presented within Accrued Liabilities, and the non-current portion of operating lease liabilities are presented within Other Non-Current Liabilities on the consolidated balance sheet.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, the Company uses an incremental collateralized borrowing rate based on the information available at commencement date, including lease term, in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Operating lease expense is recognized on a straight-line basis over the lease term.

The Company's operating lease portfolio includes field equipment such as compressors and amine units, office space and office equipment. The Company currently does not have any financing leases.

Our compressor and amine unit arrangements are typically structured with a non-cancelable primary term of one to two-years and continue thereafter on a month-to-month basis subject to termination by either party with thirty days notice. The Company's compressor and amine unit rental agreements represent operating leases with a lease term that equals the primary non-cancelable contract term. Upon completion of the primary term, both parties have substantive rights to terminate the lease. As a result, enforceable rights and obligations do not exist under the rental agreement subsequent to the primary term.

The Company enters into daywork contracts for drilling rigs with third parties to support its drilling activities. The drilling rig arrangements are typically structured with a term that is in effect until drilling operations are completed on a contractually-specified well or well pad. Upon mutual agreement with the contractor, the Company typically has the option to extend the contract term for additional wells or well pads by providing thirty days notice prior to the end of the original contract term. Drilling rig arrangements represent short-term operating leases. The accounting guidance requires the Company to make an assessment at contract commencement if it is reasonably certain that it will exercise the option to extend the term.

Due to the continuously evolving nature of the Company's drilling schedules and the potential volatility in commodity prices in an annual period, the Company's strategy to enter into shorter term drilling rig arrangements allows it the flexibility to respond to changes in our operating and economic environment. The Company exercises its discretion in choosing to extend or not extend contracts on a rig-by-rig basis depending on the conditions present at the time the contract expires. At the time of contract commencement, the Company has determined it cannot conclude with reasonable certainty if it will choose to extend the contract beyond its original term. Pursuant to the successful efforts method of accounting, these costs are capitalized as part of natural gas and oil properties on our balance sheet when paid.

The Company leases a small part of the corporate building it owns to a third-party, with a lease term that ends in 2023 and is non-cancelable. Third-party leasing income is insignificant and is included in Acquisition Costs and Other on the consolidated statements of operations.
