Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Accruals for loss contingencies arising from claims, assessments, litigation, environmental and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. As of December 31, 2018 and December 31, 2017, there were no accruals for loss contingencies. Litigation We are subject to governmental and regulatory controls arising in the ordinary course of business. It is the opinion of management that any claims and litigation involving the Company is not likely to have a material adverse effect on the reported position or results of operations. Environmental Matters As an owner of the infrastructure assets and with rights to surface lands, the Company is subject to various local and federal laws and regulations relating to discharge of materials into, and protection of, the environment. These laws and regulations may, among other things, impose liability on the Company for the cost of pollution clean-up resulting from operations and subject us to liability for pollution damages. In some instances, Altus Midstream may be directed to suspend or cease operations. The Company maintains insurance coverage, which management believes is customary in the industry, although insurance does not fully cover against all environmental risks. Additionally, there can be no assurance that current regulatory requirements will not change or past non-compliance with environmental laws will not be discovered. Contractual Obligations Altus Midstream’s existing fee-based revenue agreements, which have no minimum volume or firm transportation commitments, are underpinned by acreage dedications covering Alpine High. Pursuant to these agreements, Altus Midstream is obligated to perform low and high pressure gathering, processing, dehydration, compression, treating, conditioning, and transportation on all volumes produced from the dedicated acreage, so long as Apache has the right to market such gas. Pursuant to the COMA with Apache, Altus Midstream will indirectly receive G&A support services including information technology, risk management, corporate planning, accounting, cash management, human resources, and other general corporate services. The COMA established a fixed annual support services fee to Apache of $3.0 million in 2019, $5.0 million in 2020, and $7.0 million in 2021. Beginning in 2022 through the term of the COMA, the associated fee will be $9.0 million annually and may be adjusted upwards based on actual incurred costs. Concurrent with the closing of the Business Combination, Altus Midstream entered into the Lease Agreement with Apache, relating to the use of certain office buildings, warehouse and storage facilities located in Reeves County, Texas. Under the terms of the Lease Agreement, Altus Midstream shall pay to Apache on a monthly basis the sum of (i) a base rental charge of $44,500 and (ii) an amount based on Apache’s estimate of the annual costs it shall incur in connection with the ownership, operation, repair, and/or maintenance of the facilities. The initial term of the Lease Agreement is for four years and may be extended by Altus Midstream for three additional, consecutive periods of twenty-four months. Additionally, upon exercising the contributed Pipeline Options to acquire equity interests in five separate third-party pipeline projects, the Company may be required to fund future capital expenditures for their equity interest share in the development of the pipeline as referenced in Note 2 — Recapitalization Transaction, Note 9 — Joint Venture Equity Interest and Note 13 — Subsequent Events. At December 31, 2018 and December 31, 2017, there were no other material contractual obligations related to the entities included in the consolidated financial statements other than the performance of asset retirement obligations as referenced in Note 7 — Asset Retirement Obligations and required credit facility fees discussed in Note 5 — Debt and Financing Costs.
