Critical Accounting Policies and Estimates
Alpine High Midstream prepares its combined financial statements and the accompanying notes in conformity with GAAP, which require Alpine High Midstream’s management to make estimates and assumptions about future events that may affect the reported amounts. Management of Alpine High Midstream identifies certain accounting policies as critical based on, among other things, their impact on the portrayal of Alpine High Midstream’s financial condition, results of operations, or liquidity and the degree of difficulty, subjectivity, and complexity in their deployment. Critical accounting policies cover accounting matters that are inherently uncertain because the future resolution of such matters is unknown. Management of Alpine High Midstream routinely discusses the development, selection, and disclosure of each of the critical accounting policies. The following is a discussion of Alpine High Midstream’s most critical accounting policies.
Property, Equipment, and Depreciation
Property and equipment are recorded at cost and consist of the costs incurred to acquire and construct gathering, transmission, and processing facilities including capitalized interest. Additionally, costs incurred for improvements that substantially add to the productive capacity or extend the useful life of the related assets are capitalized. Property and equipment are stated at the lower of historical cost less accumulated depreciation, or fair value, if the long-lived assets are impaired in future periods.
Depreciation is computed over the asset’s estimated useful life using the straight line method based on estimated useful lives and estimated asset salvage values. Determination of depreciation expense requires judgment regarding the estimated useful lives and salvage values of property and equipment. Depreciation on capitalized costs begins when the assets are placed into service as completed and operational. As circumstances warrant, depreciation estimates are reviewed to determine if any changes in the underlying assumptions are necessary. The estimated lives are generally 30 years for plants and facilities and 40 years for pipelines.
Maintenance, repairs, and minor overhauls are expensed as incurred.
Asset Retirement Obligation and Accretion
Alpine High Midstream has contractual obligations to remove tangible equipment and restore land at the end of operations. Alpine High Midstream’s removal and restoration obligations are primarily associated with removing and disposing of tangible property, including gathering system equipment, pipelines, and gas processing facilities. Estimating the future restoration and removal costs is difficult and requires management to make estimates and judgments. Asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, safety, and public relations considerations.
ARO associated with retiring tangible long-lived assets is recognized as a liability in the period in which the legal obligation is incurred and becomes determinable. The liability is offset by a corresponding increase in the underlying asset. The ARO liability reflects the estimated present value of the amount of dismantlement, removal, site reclamation, and similar activities associated with Alpine High Midstream’s midstream infrastructure assets. Management of Alpine High Midstream utilizes current labor, equipment, and construction costs to estimate the expected cash outflows for retirement obligations. Inherent in the present value calculation are numerous assumptions and judgments, including the ultimate settlement amounts, inflation factors, credit- adjusted discount rates, timing of settlement, and changes in the legal, regulatory, environmental, and political environments. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value.
Long-Lived Asset Impairments
Long-lived assets used in operations, including gathering, transmission, and processing facilities, are assessed for impairment whenever changes in facts and circumstances indicate a possible significant deterioration in future cash flows expected to be generated by an asset group. Individual assets are grouped for impairment purposes based on a judgmental assessment of the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. If there is an indication the carrying amount of an asset may not be recovered, the asset is assessed by management through an established process in which changes to significant assumptions such as prices, volumes, and future development plans are reviewed. If, upon review, the sum of the undiscountedpre-tax cash flows is less than the carrying value of the asset group, the carrying value is written down to estimated fair value. Because there usually is a lack of quoted market prices for long-lived assets, the fair value of impaired assets is assessed by management using the income approach.
