Description of the Business and Basis of Presentation DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION
Description of the Business
DT Midstream is an owner, operator, and developer of an integrated portfolio of natural gas midstream assets. The Company provides multiple, integrated natural gas services to customers through two segments: (i) Pipeline, which includes interstate pipelines, intrastate pipelines, storage systems, lateral pipelines including related treatment plants and compression and surface facilities, and (ii) Gathering, which includes gathering systems, related treatment plants, and compression and surface facilities. DT Midstream's Pipeline segment also includes joint venture interests in equity method investees which own and operate interstate pipelines that connect to DT Midstream’s wholly owned assets.
DT Midstream’s core assets strategically connect key demand centers in the Midwestern U.S., Eastern Canada and Northeastern U.S. regions to the premium production areas of the Marcellus/Utica natural gas formation in the Appalachian Basin, and connect key demand centers and LNG export terminals in the Gulf Coast region to premium production areas of the Haynesville natural gas formation.
In connection with the Separation from DTE Energy, on January 13, 2021, DTE Gas Enterprises, LLC, and its consolidated subsidiaries converted into a Delaware corporation pursuant to a statutory conversion and changed its name to DT Midstream, Inc. ("DT Midstream"). At the conversion, DT Midstream issued 1,000 shares of common stock at $0.01 par value to its parent, a subsidiary of DTE Energy. As DT Midstream was a single member LLC as of December 31, 2020, and a corporation with stockholders' equity as of December 31, 2022 and 2021, Consolidated Statements of Changes in Stockholders' Equity/Member's Equity are presented as of December 31, 2022, 2021, and 2020. In June 2021, the DT Midstream Board of Directors authorized the issuance of an additional 96,731,466 common shares in anticipation of the Separation, for a total of 96,732,466 common shares issued and outstanding. DT Midstream is authorized to issue 50,000,000 shares of preferred stock at $0.01 par value. No preferred stock was issued or outstanding as of December 31, 2022 and 2021.
On July 1, 2021, DTE Energy completed the Separation through the distribution of 96,732,466 shares of DT Midstream common stock to DTE Energy shareholders. Following the Separation on July 1, 2021, DT Midstream became an independent public company listed under the symbol "DTM" on the NYSE. DTE Energy did not retain ownership in DT Midstream.
Basis of Presentation
The Consolidated Financial Statements and Notes to Consolidated Financial Statements as of and for periods subsequent to July 1, 2021, the date of the Separation, reflect the consolidated financial position, results of operations and cash flows for DT Midstream as an independent company. Prior to the Separation, DT Midstream operated as a consolidated entity of DTE Energy and not as a standalone company. For the periods prior to the Separation, the Consolidated Financial Statements and Notes to Consolidated Financial Statements were prepared on a carve-out basis using the consolidated financial statements and accounting records of DTE Energy. The carve-out basis financial statements represent the historical financial position, results of operations, and cash flows of DT Midstream as they were historically managed in accordance with GAAP and reflect significant assumptions and allocations. The carve-out financial statements may not include all expenses that would have been incurred had DT Midstream existed as a standalone entity. Certain prior-period amounts have been reclassified to conform to current-year presentation.
GAAP requires management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from DT Midstream’s estimates. DT Midstream believes the assumptions underlying these financial statements are reasonable.
Cost Allocations
Prior to the Separation, DT Midstream received monthly allocations of general corporate expenses from DTE Energy which were classified within the appropriate Consolidated Statements of Operations line item. Operation and maintenance for the year ended December 31, 2021 included approximately $20 million of Separation-related transaction costs for legal, accounting, auditing and other professional services. Effective July 1, 2021, with the completion of the Separation, DT Midstream no longer received corporate allocations from DTE Energy.
Corporate allocation amounts from DTE Energy were as follows:
Year Ended December 31,
20212020
(millions)
Operation and maintenance$32 $29 
Other expense— 1
Total DTE Energy corporate allocations$32 $30 
Cash Management
DT Midstream's sources of liquidity include cash generated from operations and available borrowings under our Revolving Credit Facility.
Prior to the Separation, DT Midstream’s sources of liquidity included cash generated from operations and loans obtained through DTE Energy’s corporate-wide cash management program, including a working capital loan agreement. Cash was managed centrally, with certain net earnings reinvested in, and working capital requirements met from, existing liquid funds. Effective July 1, 2021, DT Midstream no longer participated in the cash management program and the working capital loan was terminated.
Principles of Consolidation
DT Midstream consolidates all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-majority owned investments are accounted for using the equity method of accounting when DT Midstream is able to significantly influence the operating policies of the investee. When DT Midstream does not influence the operating policies of an investee, the equity investment is measured at fair value, if readily determinable, or if not readily determinable, at cost less impairment, if applicable. DT Midstream eliminates all intercompany balances and transactions.
DT Midstream evaluates whether an entity is a VIE whenever reconsideration events occur. DT Midstream consolidates VIEs for which we are the primary beneficiary. If DT Midstream is not the primary beneficiary and an ownership interest is held, the VIE is accounted for under the equity method of accounting. When assessing the determination of the primary beneficiary, DT Midstream considers all relevant facts and circumstances, including: the power, through voting or similar rights, to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the expected losses and/or the right to receive the expected returns of the VIE. DT Midstream performs ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.
The maximum risk exposure for consolidated VIEs is reflected on DT Midstream’s Consolidated Statements of Financial Position. DT Midstream owns an 85% interest in the Stonewall Gas Gathering VIE and is the primary beneficiary, therefore Stonewall Gas Gathering is consolidated. DT Midstream owns a 50% interest in the South Romeo VIE and is the primary beneficiary, therefore South Romeo is consolidated.
The following table summarizes the major line items in the Consolidated Statements of Financial Position for consolidated VIEs as of December 31, 2022 and 2021. All assets and liabilities of a consolidated VIE are presented where it has been determined that a consolidated VIE has either (1) assets that can be used only to settle obligations of the VIE or (2) liabilities for which creditors do not have recourse to the general credit of the primary beneficiary. The assets and liabilities of consolidated VIEs that meet the definition of a business and whose assets can be used for purposes other than the settlement of the VIEs' obligations have been excluded from the table below.
Amounts for consolidated VIEs are as follows:

DT Midstream had a variable interest in an investment in certain assets in the Utica shale region that was accounted for as a Note receivable — third party. DT Midstream did not have an ownership interest in the entity and was not the primary beneficiary. This investment was sold during the second quarter 2022. See Note 2, "Significant Accounting Policies – Financing Receivables" to the Consolidated Financial Statements for additional discussion.
Amounts for the non-consolidated VIE were as follows:

Related Parties
Transactions between DT Midstream and DTE Energy prior to the Separation, as well as all transactions between DT Midstream and its equity method investees, have been presented as related party transactions in the accompanying Consolidated Financial Statements. See Note 15, "Related Party Transactions" to the Consolidated Financial Statements.
Equity Method Investments
Investments in non-consolidated affiliates that are not controlled by DT Midstream, but over which we have significant influence, are accounted for using the equity method of accounting. Under the equity method, investments are recorded at historical cost as an asset and adjusted for capital contributions, dividends and distributions received, and the Company's share of the investee's earnings or losses, which are recorded as earnings from equity method investees on the Consolidated Statements of Operations. DT Midstream's equity method investments are periodically evaluated for certain factors that may be indicative of other-than-temporary impairment. As of December 31, 2022 and 2021, DT Midstream’s carrying amounts of investments in equity method investees exceeded our share of the underlying equity in the net assets of the investees by $368 million and $32 million, respectively. The difference will be amortized over the life of the underlying assets. As of December 31, 2022 and 2021, DT Midstream's consolidated retained earnings balance includes undistributed earnings from equity method investments of $43 million and $84 million, respectively.
Equity method investees are described below:

On October 7, 2022, DT Midstream closed on the $552 million purchase of an additional 26.25% ownership interest in Millennium Pipeline from National Grid. The transaction was financed with cash on hand and available capacity under the Company's Revolving Credit Facility. The purchase constituted National Grid's full ownership interests in Millennium Pipeline, and brought DT Midstream's total ownership interest in Millennium Pipeline to 52.50%. DT Midstream accounts for its ownership interest in Millennium Pipeline under the equity method of accounting. Millennium is not a VIE and DT Midstream does not have a controlling interest due to shared control with its partner over all of Millennium's significant business activities.

Cash and Cash Equivalents
Cash and cash equivalents include cash in banks and highly liquid money market investments with remaining maturities of three months or less, when purchased. Cash equivalents are stated at cost, which approximates fair value.
Financing Receivables
Financing receivables are primarily composed of trade accounts receivable and notes receivable, which are stated at net realizable value.
DT Midstream regularly monitors the credit quality of its financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. DT Midstream has three internal grades of credit quality, with internal grade 1 as the lowest risk and internal grade 3 as the highest risk. The related credit quality indicators and risk ratings utilized to develop the internal grades have been updated through December 31, 2022. As of December 31, 2022, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1.
Notes receivable are typically considered delinquent (past due) when payment is not received for periods ranging from 60 to 120 days. DT Midstream ceases accruing interest income (nonaccrual status) and may either write off or establish an allowance for expected credit loss for the note receivable when it is expected that all principal or interest amounts due will not be collected in accordance with the note's contractual terms. In determining an allowance for expected credit losses for or the write off of notes receivable, DT Midstream considers the historical payment experience and other factors that are expected to have a specific impact on collection, including existing and future economic conditions.
Cash receipts for notes receivable on nonaccrual status that do not bring the account contractually current are first applied to contractually owed past due interest, with any remainder applied to principal. Recognition of interest income is generally resumed when the note receivable becomes contractually current.
DT Midstream had an investment in certain assets in the Utica shale region which was accounted for as a Note receivable — third party. In the second quarter 2021, we assessed the note receivable for expected loss and recorded a $19 million loss on the note receivable to Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. Additionally, DT Midstream ceased accruing interest on the note receivable balance and reclassified the note to an Internal grade 3 receivable. Subsequently, as cash payments were received, a portion was recognized as interest income. A third party purchased our investment in certain assets in the Utica shale region based on significantly improved commodity pricing during the second quarter 2022 for proceeds of $22 million. This resulted in a gain of $17 million recorded in Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. DT Midstream maintains no continuing involvement with the note receivable.
There are no notes receivable on nonaccrual status and no past due financing receivables as of December 31, 2022.
For trade accounts receivable, the customer allowance for expected credit loss is calculated based on specific review of future collections based on receivable balances generally in excess of 30 days. Existing and future economic conditions, historical loss rates, customer trends and other relevant factors that may affect our ability to collect are also considered. Receivables are written off on a specific identification basis and determined based on the particular circumstances of the associated receivable. Uncollectible expense (recovery) was zero for the years ended December 31, 2022 and 2021, and $(2) million for the year ended December 31, 2020.
The following table presents a roll-forward of the activity for DT Midstream's financing receivables' (accounts receivable and notes receivable) allowance for expected credit loss. Our collections on accounts receivable from customers are current, and no material rate of historical loss was noted, which resulted in no allowance for expected credit loss as of December 31, 2022. The balance is shown as a deduction from the respective financing receivable's balance in the Consolidated Statements of Financial Position.

Property, Plant, and Equipment
Property is stated at cost and includes construction-related labor, materials, and overhead. Expenditures for maintenance and repairs are charged to expense when incurred. DT Midstream's property, plant and equipment is depreciated over its estimated useful life using the straight-line method. See Note 6, "Property, Plant, and Equipment and Intangible Assets" to the Consolidated Financial Statements.
Intangible Assets
Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. See Note 6, "Property, Plant, and Equipment and Intangible Assets" to the Consolidated Financial Statements.
Long-Lived Assets
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds the expected undiscounted future cash flows generated by the asset, an impairment loss is recognized resulting in the asset being written down to its estimated fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell.
Operation and Maintenance
Operation and maintenance is primarily comprised of costs for labor and employee benefits, outside services, materials, compression, purchased natural gas, operating lease costs, office costs, and other operating and maintenance costs. Corporate allocations from DTE Energy, including Separation-related transaction costs for legal, accounting, auditing and other professional services DTE Energy incurred for the benefit of DT Midstream, were also included in operation and maintenance prior to the Separation.
Depreciation and Amortization
Depreciation and amortization is related to Property, plant and equipment and Customer relationships and other intangible assets, net, used in our transportation, storage and gathering businesses.
Other Income - Blue Union/LEAP Settlement
In the third quarter 2020, DT Midstream reached a post-acquisition settlement with M5 Louisiana Holdings, LLC. The settlement did not relate to the Blue Union/LEAP acquisition price. The proceeds of $20 million are included in Other (income) and expense on the Consolidated Statement of Operations for the year ended December 31, 2020.

Revenue from Contract with Customer [Abstract]  
Revenue REVENUE
Significant Accounting Policy
Pipeline revenues consist of services related to the gathering, transportation and/or storage of natural gas. Gathering revenues consist of services related to the gathering, processing, and/or treating of natural gas. Revenue is measured based upon the pricing or consideration for such services specified in the contract with a customer. Consideration may consist of both fixed components including fixed demand charges and fixed deficiency fee rates for MVCs, and variable components including fixed rates for the actual volumes flowed under interruptible services and other associated fees.
DT Midstream's contracts with customers generally contain a single performance obligation, which is a promise to deliver either a distinct service or a series of distinct services to the customer. When multiple performance obligations exist, the contract consideration is allocated between the performance obligations based on the relative standalone selling price, which is determined by prices charged to customers or the adjusted market assessment approach. The adjusted market assessment approach involves evaluating the market in which DT Midstream sells services and estimating the price that a customer in that market would be willing to pay.
Revenue is recognized when performance obligations are satisfied by delivering a service to a customer, which occurs when the service is provided to the customer. When a customer simultaneously receives and consumes the service provided, revenue is recognized over time. Alternatively, if it is determined that the criteria for recognition of revenue over time is not met, the revenue is considered to be recognized at a point in time. DT Midstream's revenues, including estimated unbilled amounts, are generally recognized over time as actual services are provided, or ratably over time when providing a stand-ready service. Unbilled amounts are generally determined using preliminary meter data volumes and contracted pricing, and typically result in minor adjustments. Generally, uncertainties in the variable consideration components are resolved and revenue amounts are known at the time of recognition. DT Midstream has determined that the above methods represent a faithful depiction of delivering a service to the customer. Revenues are typically billed and consideration received monthly, however, certain deficiency fees related to MVCs are billed quarterly or annually.
Certain of our Gathering contracts allow for the recovery of production-related operating expenses, which are recorded as revenue and operating expense.

Nature of Services
DT Midstream primarily provides two types of revenue services: firm service and interruptible service. Firm service revenue contracts provide for fixed revenue commitments regardless of actual volumes of natural gas that flow, which leads to more stable operating performance, revenues and cash flows and limits our exposure to natural gas price fluctuations. Firm service revenue contracts are typically long-term and structured using fixed demand charges or MVCs with fixed deficiency fee rates. Contracts structured using fixed demand charges contain a performance obligation of a stand-ready series of distinct services that are substantially the same with the same pattern of transfer to the customer, therefore revenue is recognized ratably over time. Contracts structured using MVCs with fixed deficiency fee rates require customers to transport or store a minimum volume of natural gas over a specified time period. If a customer fails to meet its MVCs for the specified time period, the contract consideration includes a fixed rate for the actual volumes transported, gathered or stored, and a deficiency fee for the shortfall between the MVCs and the actual volumes transported, gathered or stored. If a customer exceeds its MVC for the specified time period, the contract consideration is based on fixed rates for the actual volumes transported, gathered or stored. The contract consideration is allocated to each distinct monthly performance obligation, consistent with the allocation objective and based upon the level of effort required to satisfy the service obligation. Revenues are generally recognized over time based on the output measure of natural gas volumes transported, gathered or stored, with the recognition of the deficiency fee revenue in the period when it is known the customer cannot make up the deficient volumes in the specified time period. Interruptible service revenue contracts typically contain fixed rates, with total consideration dependent on actual natural gas volumes that flow. Interruptible service revenues are recognized over time based on the output measure of natural gas volumes transported, gathered or stored.
Contract Liabilities

The contract liabilities at DT Midstream generally represent amounts paid by customers for which the associated performance obligation has not yet been satisfied. Performance obligations associated with contract liabilities are principally related to customer prepayments. Contract liabilities associated with these services are recognized upon delivery of the service to the customer.
The following table presents contract liability amounts as of December 31, 2022 that are expected to be recognized as revenue in future periods:

Transaction Price Allocated to the Remaining Performance Obligations
In accordance with optional exemptions available under Topic 606, DT Midstream does not disclose the value of unsatisfied performance obligations for (1) contracts with an original expected length of one year or less, (2) with the exception of fixed consideration, contracts for which the amount of revenue recognized depends upon DT Midstream's invoices for actual volumes transported, gathered or stored, and (3) contracts for which variable consideration relates entirely to an unsatisfied performance obligation.
Such contracts consist of various types of performance obligations, including providing midstream services. Contracts with variable volumes and/or variable pricing, including those with pricing provisions tied to a consumer price or other index, have also been excluded as the related contract consideration is variable at the contract inception. Contract lengths vary from cancellable to multi-year.

Costs to Obtain or Fulfill a Contract
DTM recognizes an asset from the costs incurred to obtain a contract only if it expects to recover those costs. In addition, the costs to fulfill a contract are capitalized if the costs are specifically identifiable to a contract, would result in enhancing resources that will be used in satisfying performance obligations in the future, and are expected to be recovered. These capitalized costs are amortized as a reduction of revenue on a systematic basis consistent with the pattern of transfer of the services to which such costs relate.
As of both December 31, 2022 and 2021, the Company had capitalized costs to obtain or fulfill a contract of $19 million, which are included in other current assets and other noncurrent assets in the accompanying Consolidated Statements of Financial Position. During the year ended December 31, 2022, 2021, and 2020, we recognized $1 million of amortization expense related to such capitalized costs.

Income Tax Disclosure [Abstract]  
Income Taxes INCOME TAXES
Significant Accounting Policy – Accounting for Income Taxes
The Company records the effect of income taxes in accordance with GAAP, which provides for the use of an asset and liability approach.
Deferred income tax assets and liabilities are recognized for temporary differences between the basis of assets and liabilities for financial reporting and tax purposes and measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities as a result of changes in the enacted rates is recognized in earnings in the period of enactment.
Our recognition of deferred tax assets is based upon a more-likely-than-not criterion. We routinely assess realizability based on objectively weighted available positive and negative evidence.
We account for uncertainties in income taxes using a benefit recognition model with a two-step approach: a more-likely-than-not recognition criterion, and a measurement attribute that measures the position as the largest amount of tax benefit that it is greater than a 50% likelihood of being realized upon ultimate settlement. If the benefit does not meet the more likely than not criteria for being sustained on its technical merits, no benefit will be recorded. Uncertain tax positions that relate only to timing of when an item is included on a tax return are considered to have met the recognition threshold.
The Separation – Tax Considerations
For periods prior to the Separation, discussed at Note 1, "Description of the Business and Basis of Presentation", the income tax provision has been presented on a stand-alone basis as if DT Midstream filed separate federal, state, local, and foreign income tax returns, referred to as the separate return method.
Tax Legislation
On July 8, 2022, the Commonwealth of Pennsylvania enacted House Bill (H.B.) 1342 which includes a corporate income tax rate reduction from 9.99% to 4.99% that will phase-in over a nine-year period. As a corporate taxpayer in Pennsylvania and in accordance with tax accounting guidance, DT Midstream recorded a $25 million impact of remeasuring our deferred tax balances to continuing operations (tax expense) in the year ended December 31, 2022.
On August 16, 2022, President Biden signed H.R. 5374 ("Inflation Reduction Act" or "IRA") into law. The IRA includes a number of tax, health care, and energy-related provisions, which largely go into effect in tax years after December 31, 2022, and do not have a material impact on our consolidated financial statements for the year ended December 31, 2022.

As of December 31, 2022 and 2021, DT Midstream does not have any unrecognized tax benefits.
For periods prior to the Separation, DT Midstream was a member of the consolidated tax return of DTE Energy. As of the balance sheet date, DTE Energy’s federal income tax returns for 2021 and subsequent years remains subject to examination by the Internal Revenue Service (IRS). DTE Energy also files in multiple states, the statutes of which are open to examination for various periods.
For periods after the Separation, DT Midstream's income tax returns remain subject to examination by federal, state, and local taxing jurisdiction

Earnings Per Share [Abstract]  
Earnings Per Share and Dividends EARNINGS PER SHARE AND DIVIDENDS
Basic earnings per share is calculated by dividing Net Income attributable to DT Midstream by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the dilution that would occur if any potentially dilutive instruments were exercised or converted into common shares. Restricted stock units and performance shares, including dividend equivalents on those grants, are potentially dilutive and, if dilutive, are included in the determination of weighted average shares outstanding. Restricted stock units and performance shares do not receive cash dividends, as such, these awards are not considered participating securities.
DT Midstream issued 1,000 shares of common stock at $0.01 par value to its parent, a subsidiary of DTE Energy, in January 2021. The DT Midstream Board of Directors authorized the issuance of an additional 96,731,466 common shares on June 30, 2021 for a total of 96,732,466 common shares issued and outstanding at the Separation date. This share amount is treated as issued and outstanding and utilized for the calculation of historical basic and diluted earnings per share for all periods prior to the Separation.

Fair Value Disclosures [Abstract]  
Fair Value FAIR VALUE
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable inputs. DT Midstream makes certain assumptions it believes that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. DT Midstream believes it uses valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.
A fair value hierarchy has been established that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. All assets and liabilities are required to be classified in their entirety based on the lowest level of input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and its placement within the fair value hierarchy. DT Midstream classifies fair value balances based on the fair value hierarchy defined as follows:

Amendment to Credit Agreement
On October 19, 2022, DT Midstream amended the Credit Agreement to increase the Revolving Credit Facility commitments by $250 million to aggregate commitments of $1.0 billion. The amendment also extended the Revolving Credit Facility maturity date to October 19, 2027, replaced the Revolving Credit Facility's LIBOR interest rate references with SOFR, and incorporated various amendments, including amendments to pricing, guarantee and collateral provisions, that will become effective if DT Midstream receives an investment-grade rating from two of the three credit rating agencies.
Debt Issuances
On June 9, 2021, DT Midstream issued the senior unsecured notes of $1.1 billion in aggregate principal amount due June 15, 2029 (the "2029 Notes") and $1.0 billion in aggregate principal amount due June 15, 2031 (the "2031 Notes").
In April 2022, DT Midstream issued $600 million in aggregate principal amount of 4.300% senior secured notes due April 2032 (the "2032 Notes"). The 2032 Notes are guaranteed by certain of DT Midstream's subsidiaries and secured by a first priority lien on certain assets of DT Midstream and its subsidiary guarantors that secure DT Midstream's existing credit facilities. The 2032 Notes have a security fall away provision where the collateral securing the notes will be released if DT Midstream receives an investment-grade rating from two of the three credit rating agencies. As part of the issuance of the 2032 Notes, DT Midstream's capitalized debt issuance and discount costs are approximately $4 million and $1 million, respectively.
Debt Redemptions
DT Midstream used $593 million of the net proceeds from the sale of the 2032 Notes to make a partial repayment on the existing indebtedness under the Term Loan Facility. As a result, required quarterly principal payments were eliminated, and the remaining Term Loan Facility balance is not due until maturity in 2028. There were no prepayment costs in conjunction with the partial redemption of the Term Loan Facility. The early redemption resulted in a loss on extinguishment of debt of $9 million and loss on modification of debt of $4 million relating to the write-off of unamortized discount and issuance costs, which was recorded as a loss from financing activities on DT Midstream’s Consolidated Statements of Operations for the year ended December 31, 2022.

Borrowings under the Revolving Credit Facility are used for general corporate purposes, acquisitions including our Millennium Pipeline acquisition, and letter of credit issuances to support DT Midstream's operations and liquidity. The Revolving Credit Facility incurred initial issuance costs of $7 million in 2021 and Credit Agreement amendment costs of $3 million in 2022, which are included net of amortization in Other noncurrent assets on DT Midstream's Consolidated Statements of Financial Position as of December 31, 2022. These costs are being amortized over the extended term of the Revolving Credit Facility.
The Credit Agreement covering the Term Loan Facility and Revolving Credit Facility includes financial covenants that DT Midstream must maintain. These covenants restrict the ability of DT Midstream and its subsidiaries to incur additional indebtedness and guarantee indebtedness, create or incur liens, engage in mergers, consolidations, liquidations or dissolutions, sell, transfer or otherwise dispose of assets, make investments, acquisitions, loans or advances, pay dividends and distributions or repurchase capital stock, prepay, redeem or repurchase certain junior indebtedness, enter into agreements that limit the ability of the restricted subsidiaries to make distributions to DT Midstream or the ability of DT Midstream and its restricted subsidiaries to incur liens on assets and enter into certain transactions with affiliates. The Term Loan Facility requires the maintenance of a minimum debt service coverage ratio of 1.1 to 1, and the Revolving Credit Facility requires maintenance of (i) a maximum consolidated net leverage ratio of 5 to 1, and (ii) a minimum interest coverage ratio of no less than 2.5 to 1. The debt service coverage ratio means the ratio of annual consolidated EBITDA to debt service, as defined in the Credit Agreement. The consolidated net leverage ratio means the ratio of net debt determined in accordance with GAAP to annual consolidated EBITDA. The interest coverage ratio means the ratio of annual consolidated EBITDA to annual interest expense, as defined in the Credit Agreement. At December 31, 2022, the debt service coverage ratio, the consolidated net leverage ratio and the interest coverage ratio was 6.9 to 1, 3.8 to 1 and 6.3 to 1, respectively, and DT Midstream was in compliance with these financial covenants.
Dividend Restrictions
The indenture governing the 2029 and 2031 Notes permits the payment of quarterly dividends on common stock in each fiscal year up to a dividend capacity calculated as defined in the indenture. For 2022, the dividend capacity remaining at year end was $200 million.
The Credit Agreement permits the payment of quarterly dividends on common stock in each fiscal year as long as giving pro forma effect thereto, DT Midstream maintains a first lien net leverage ratio that does not exceed 3.25 to 1. DT Midstream maintained such first lien net leverage ratio at December 31, 2022.

Leases LEASES
Lessee
Leases at DT Midstream are primarily comprised of equipment and buildings with terms ranging from approximately 3 to 11 years.
A lease is deemed to exist when DT Midstream has the right to control the use of identified property, plant or equipment, as conveyed through a contract, for a certain time period and consideration paid. The right to control is deemed to occur when DT Midstream has the right to obtain substantially all of the economic benefits of the identified assets and the right to direct the use of such assets.
Lease liabilities are determined utilizing a discount rate to determine the present values of lease payments. GAAP requires the use of the rate implicit in the lease when it is readily determinable. When the rate implicit in the lease is not readily determinable, the incremental borrowing rate is used. The incremental borrowing rate is based upon the rate of interest that would have been paid on a collateralized basis over similar contract terms to that of the leases. The incremental borrowing rates have been determined utilizing an implied secured borrowing rate based upon an unsecured rate for a similar time period of remaining lease terms, which is then adjusted for the estimated impact of collateral.
DT Midstream has leases with non-index-based escalation clauses for fixed dollar or percentage increases.
DT Midstream has certain leases which contain purchase options. Based upon the nature of the leased property and terms of the purchase options, DT Midstream has determined it is not reasonably certain that such purchase options will be exercised. Thus, the impact of the purchase options has not been included in the determination of right-of-use assets and lease liabilities for the subject leases.
DT Midstream has certain leases which contain renewal options. Where the renewal options were deemed reasonably certain to occur, the impacts of such options were included in the determination of the right of use assets and lease liabilities.
DT Midstream has agreements with lease and non-lease components, which are generally accounted for separately. Consideration in a lease is allocated between lease and non-lease components based upon the estimated relative standalone prices.

Vector Pipeline Line of Credit
DT Midstream is the lender under a revolving term credit facility to Vector Pipeline, the borrower, in the amount of Canadian $70 million. The credit facility was executed in response to the passage of Canadian regulations requiring oil and gas pipelines to demonstrate their financial ability to respond to a catastrophic event and exists for the sole purpose of satisfying these regulations. Vector Pipeline may only draw upon the facility if the funds are required to respond to a catastrophic event. The maximum potential payout at December 31, 2022 is USD $52 million. The funding of a loan under the terms of the credit facility is considered remote.
Environmental Contingencies
In order to comply with certain state environmental regulations, DT Midstream has an obligation to restore pipeline right-of-way slope failures that may arise in the ordinary course of business in the Utica and Marcellus formations. Slope restoration expenditures are typically capital in nature. As of December 31, 2022 and 2021, DT Midstream had accrued contingent liabilities of $19 million and $20 million, respectively, for future slope restoration expenditures. The accrual is included in Other current liabilities and Other liabilities in the Consolidated Statements of Financial Position. DT Midstream believes the accrued amounts are sufficient to cover estimated future expenditures.
Bankruptcies
DT Midstream’s Gathering segment provides gas gathering services under customer contracts with gas shippers in the Utica and Marcellus formations in Pennsylvania and West Virginia, and one of these customers, Arsenal Resources, entered into bankruptcy. In 2020, DT Midstream received payments of approximately $4 million from Arsenal Resources under the terms of a bankruptcy cure agreement. There was no allowance for expected credit loss remaining at December 31, 2022 and 2021

Stock-based Compensation and Defined Contribution Plans STOCK-BASED COMPENSATION AND DEFINED CONTRIBUTION PLANS
The DT Midstream, Inc. Long-Term Incentive Plan ("DT Midstream Plan") permits the grant of incentive and nonqualified stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares, and performance units to employees, consultants and members of DT Midstream's Board of Directors. As a result of a restricted stock award grant, restricted stock unit or performance share settlement, or by exercise of a stock option, DT Midstream may issue common stock from its authorized but unissued common stock and/or from outstanding common stock acquired by or on behalf of DT Midstream in the participant's name. The DT Midstream Plan began on the Separation date. Key provisions of the DT Midstream Plan are:
•Authorized limit as of December 31, 2022 was 4,750,000 shares of common stock. The authorized limit increases annually on January 1 by the lesser of 1,750,000 shares of common stock or the amount determined by the DT Midstream Board of Directors.
•Prohibits the grant of a stock option with an exercise price that is less than the fair market value of DT Midstream's stock on the grant date.
Prior to the Separation, DT Midstream employees participated in DTE Energy's Long-Term Incentive Plan. At the Separation, outstanding DT Midstream employee restricted stock awards and performance share awards were modified or settled as follows:
•DTE Energy restricted stock awards were converted into DT Midstream restricted stock units;
•DTE Energy settled two-thirds of the 2019 performance share awards and one-third of the 2020 performance share awards; and
•Remaining unsettled DTE Energy performance share awards were converted into DT Midstream performance share awards.
The restricted stock awards and performance share awards were converted using a formula designed to preserve the fair value of the awards immediately prior to the Separation. All converted awards retained the vesting schedule of the original awards. The conversion of the restricted stock awards and performance share awards qualified as an accounting modification under GAAP. The pre- and post- Separation fair value of the awards was compared, and any incremental fair value was added to the original grant date fair value of the awards. The Separation modification gave rise to incremental fair value of approximately $1 million for the performance share awards granted in January 2021 and is reflected in the compensation cost and the unrecognized compensation costs described below. The Separation modification did not result in incremental fair value for any other converted restricted stock awards or performance share awards.
Prior to the Separation, DT Midstream received an allocation of costs from DTE Energy associated with stock-based compensation. Allocated costs for the year ended December 31, 2020 and the first six months of 2021 are included in the table below. No costs were allocated after July 1, 2021. The following table summarizes the components of stock-based compensation for DT Midstream.

Restricted Stock Units
Restricted stock units granted under the DT Midstream Plan are for a specified number of shares of DT Midstream common stock that entitle the holder to receive common stock, a cash payment, or a combination thereof at the end of the specified vesting period, which is generally three or four years. Restricted stock units are deemed to be equity awards. The fair value of restricted stock units is based on the closing price of DT Midstream's common stock on the grant date. The fair value is amortized to compensation expense on a graded vesting schedule over the vesting period. Restricted stock units are settled with DT Midstream common stock. Fractional shares are settled in cash.
During the period beginning on the grant date of restricted stock units and ending on the vesting date, the number of restricted stock units granted will increase, assuming full dividend reinvestment on the dividend payment date. The recipient of the restricted stock unit has no shareholder rights during the vesting period. Restricted stock units are nontransferable and subject to risk of forfeiture during the vesting period. Forfeitures are recognized in the period they occur.

The intrinsic value of restricted stock units vested and issued during the years ended December 31, 2022 and 2021 was $3 million and $0.1 million, respectively. No restricted stock units were granted by DT Midstream during the years ended December 31, 2021 or 2020.
Performance Shares
Performance share awards granted under the DT Midstream Plan are for a specified number of shares of DT Midstream common stock that entitle the holder to receive common stock, a cash payment, or a combination thereof at the end of the specified vesting period, which is generally three years. Performance share awards are deemed to be equity awards. DT Midstream accrues performance share compensation expense over the vesting period based on the grant date fair value calculated using: (i) DT Midstream's closing common stock price on the grant date; (ii) the grant date fair value of the market condition; and (iii) the probable achievement of performance objectives. For the performance shares converted at the Separation, the grant date fair value was based on DTE Energy's stock price and market conditions at grant date. The number of shares issued at settlement is determined based on the achievement of certain DT Midstream performance objectives and market conditions. The performance share awards are settled with DT Midstream common stock. Fractional shares are settled in cash.
During the period beginning on the grant date of performance share awards and ending on the certification date of the DT Midstream performance objectives, the number of performance shares granted will increase, assuming full dividend reinvestment on the dividend payment date. The recipient of a performance share award has no shareholder rights during the vesting period. Performance share awards are nontransferable and are subject to risk of forfeiture during the vesting period. Forfeitures are recognized in the period they occur.

Unrecognized Compensation Costs
As of December 31, 2022, DT Midstream had $21 million of total unrecognized compensation costs related to non-vested stock incentive plan arrangements. The cost is expected to be recognized over a weighted-average period of 1.85 years.
Defined Contribution Plans

DT Midstream matches employee contributions up to certain predefined and Internal Revenue Service limits based on eligible compensation and the employee's contribution rate, and contributes additional amounts in lieu of traditional pension and post-employment healthcare benefits. Prior to the Separation, DT Midstream participated in the defined contribution retirement savings plans of DTE Energy. DT Midstream's cost for these plans was $5 million, $3 million and $2 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Related Party Transactions RELATED PARTY TRANSACTIONS
Transactions between DT Midstream and DTE Energy prior to the Separation, as well as all transactions between DT Midstream and its equity method investees, have been presented as related party transactions in the accompanying Consolidated Financial Statements.
Prior to the Separation, DTE Energy and its subsidiaries provided physical operations, maintenance, and technical support pursuant to an operating agreement for DT Midstream’s facilities. DT Midstream also utilized various services performed by DTE Energy and its subsidiaries including marketing and capacity optimization services.
Prior to the Separation, interest expense recorded in the Consolidated Statements of Operations was primarily related to interest on the Short-term borrowings due to DTE Energy, amounts of which are shown in the table below. The working capital loan agreement had interest rates of 3.3% for 2021 and 3.9% for 2020 and a term of one year. No interest expense on Short-term borrowings due to DTE Energy was incurred after the Separation.
In June 2021, DT Midstream made the following cash payments:
•Settled Short-term borrowings due to DTE Energy as of June 30, 2021 of $2,537 million
•Settled Accounts receivable due from DTE Energy and Accounts payable due to DTE Energy as of June 30, 2021 for net cash of $9 million
•Provided a one-time special dividend to DTE Energy
On July 1, 2021, DTE Energy completed the Separation through the distribution of 96,732,466 shares of DT Midstream common stock to DTE Energy shareholders. After the Separation, DTE Energy is not considered a related party of DT Midstream.

Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The Consolidated Financial Statements and Notes to Consolidated Financial Statements as of and for periods subsequent to July 1, 2021, the date of the Separation, reflect the consolidated financial position, results of operations and cash flows for DT Midstream as an independent company. Prior to the Separation, DT Midstream operated as a consolidated entity of DTE Energy and not as a standalone company. For the periods prior to the Separation, the Consolidated Financial Statements and Notes to Consolidated Financial Statements were prepared on a carve-out basis using the consolidated financial statements and accounting records of DTE Energy. The carve-out basis financial statements represent the historical financial position, results of operations, and cash flows of DT Midstream as they were historically managed in accordance with GAAP and reflect significant assumptions and allocations. The carve-out financial statements may not include all expenses that would have been incurred had DT Midstream existed as a standalone entity. Certain prior-period amounts have been reclassified to conform to current-year presentation.
GAAP requires management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from DT Midstream’s estimates. DT Midstream believes the assumptions underlying these financial statements are reasonable.
Principles of Consolidation
Principles of Consolidation
DT Midstream consolidates all majority-owned subsidiaries and investments in entities in which we have a controlling influence. Non-majority owned investments are accounted for using the equity method of accounting when DT Midstream is able to significantly influence the operating policies of the investee. When DT Midstream does not influence the operating policies of an investee, the equity investment is measured at fair value, if readily determinable, or if not readily determinable, at cost less impairment, if applicable. DT Midstream eliminates all intercompany balances and transactions.
DT Midstream evaluates whether an entity is a VIE whenever reconsideration events occur. DT Midstream consolidates VIEs for which we are the primary beneficiary. If DT Midstream is not the primary beneficiary and an ownership interest is held, the VIE is accounted for under the equity method of accounting. When assessing the determination of the primary beneficiary, DT Midstream considers all relevant facts and circumstances, including: the power, through voting or similar rights, to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the expected losses and/or the right to receive the expected returns of the VIE. DT Midstream performs ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.
The maximum risk exposure for consolidated VIEs is reflected on DT Midstream’s Consolidated Statements of Financial Position. DT Midstream owns an 85% interest in the Stonewall Gas Gathering VIE and is the primary beneficiary, therefore Stonewall Gas Gathering is consolidated. DT Midstream owns a 50% interest in the South Romeo VIE and is the primary beneficiary, therefore South Romeo is consolidated.
Cash and Cash Equivalents Cash and Cash EquivalentsCash and cash equivalents include cash in banks and highly liquid money market investments with remaining maturities of three months or less, when purchased. Cash equivalents are stated at cost, which approximates fair value.
Financing Receivables
Financing Receivables
Financing receivables are primarily composed of trade accounts receivable and notes receivable, which are stated at net realizable value.
DT Midstream regularly monitors the credit quality of its financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. DT Midstream has three internal grades of credit quality, with internal grade 1 as the lowest risk and internal grade 3 as the highest risk. The related credit quality indicators and risk ratings utilized to develop the internal grades have been updated through December 31, 2022. As of December 31, 2022, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1.
Notes receivable are typically considered delinquent (past due) when payment is not received for periods ranging from 60 to 120 days. DT Midstream ceases accruing interest income (nonaccrual status) and may either write off or establish an allowance for expected credit loss for the note receivable when it is expected that all principal or interest amounts due will not be collected in accordance with the note's contractual terms. In determining an allowance for expected credit losses for or the write off of notes receivable, DT Midstream considers the historical payment experience and other factors that are expected to have a specific impact on collection, including existing and future economic conditions.
Cash receipts for notes receivable on nonaccrual status that do not bring the account contractually current are first applied to contractually owed past due interest, with any remainder applied to principal. Recognition of interest income is generally resumed when the note receivable becomes contractually current.
DT Midstream had an investment in certain assets in the Utica shale region which was accounted for as a Note receivable — third party. In the second quarter 2021, we assessed the note receivable for expected loss and recorded a $19 million loss on the note receivable to Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. Additionally, DT Midstream ceased accruing interest on the note receivable balance and reclassified the note to an Internal grade 3 receivable. Subsequently, as cash payments were received, a portion was recognized as interest income. A third party purchased our investment in certain assets in the Utica shale region based on significantly improved commodity pricing during the second quarter 2022 for proceeds of $22 million. This resulted in a gain of $17 million recorded in Asset (gains) losses and impairments, net on the Consolidated Statement of Operations. DT Midstream maintains no continuing involvement with the note receivable.
There are no notes receivable on nonaccrual status and no past due financing receivables as of December 31, 2022.
For trade accounts receivable, the customer allowance for expected credit loss is calculated based on specific review of future collections based on receivable balances generally in excess of 30 days. Existing and future economic conditions, historical loss rates, customer trends and other relevant factors that may affect our ability to collect are also considered. Receivables are written off on a specific identification basis and determined based on the particular circumstances of the associated receivable.
Recently Issued Pronouncements
Recently Adopted Pronouncements
In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, as amended. Subsequently, in January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) - Scope, as amended. The amendments in these updates provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance can be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. Subsequently, in December 2022, the FASB issued ASU No. 2022-06, Deferral of the Sunset Date of Topic 848, which further deferred the sunset date to December 31, 2024. The optional relief is temporary and cannot be applied to contract modifications and hedging relationships entered into or evaluated after December 31, 2024. DT Midstream adopted this standard which did not have a material impact on our Consolidated Financial Statements.
Revenue
Pipeline revenues consist of services related to the gathering, transportation and/or storage of natural gas. Gathering revenues consist of services related to the gathering, processing, and/or treating of natural gas. Revenue is measured based upon the pricing or consideration for such services specified in the contract with a customer. Consideration may consist of both fixed components including fixed demand charges and fixed deficiency fee rates for MVCs, and variable components including fixed rates for the actual volumes flowed under interruptible services and other associated fees.
DT Midstream's contracts with customers generally contain a single performance obligation, which is a promise to deliver either a distinct service or a series of distinct services to the customer. When multiple performance obligations exist, the contract consideration is allocated between the performance obligations based on the relative standalone selling price, which is determined by prices charged to customers or the adjusted market assessment approach. The adjusted market assessment approach involves evaluating the market in which DT Midstream sells services and estimating the price that a customer in that market would be willing to pay.
Revenue is recognized when performance obligations are satisfied by delivering a service to a customer, which occurs when the service is provided to the customer. When a customer simultaneously receives and consumes the service provided, revenue is recognized over time. Alternatively, if it is determined that the criteria for recognition of revenue over time is not met, the revenue is considered to be recognized at a point in time. DT Midstream's revenues, including estimated unbilled amounts, are generally recognized over time as actual services are provided, or ratably over time when providing a stand-ready service. Unbilled amounts are generally determined using preliminary meter data volumes and contracted pricing, and typically result in minor adjustments. Generally, uncertainties in the variable consideration components are resolved and revenue amounts are known at the time of recognition. DT Midstream has determined that the above methods represent a faithful depiction of delivering a service to the customer. Revenues are typically billed and consideration received monthly, however, certain deficiency fees related to MVCs are billed quarterly or annually.
Certain of our Gathering contracts allow for the recovery of production-related operating expenses, which are recorded as revenue and operating expense.
Income Taxes
Significant Accounting Policy – Accounting for Income Taxes
The Company records the effect of income taxes in accordance with GAAP, which provides for the use of an asset and liability approach.
Deferred income tax assets and liabilities are recognized for temporary differences between the basis of assets and liabilities for financial reporting and tax purposes and measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities as a result of changes in the enacted rates is recognized in earnings in the period of enactment.
Our recognition of deferred tax assets is based upon a more-likely-than-not criterion. We routinely assess realizability based on objectively weighted available positive and negative evidence.
We account for uncertainties in income taxes using a benefit recognition model with a two-step approach: a more-likely-than-not recognition criterion, and a measurement attribute that measures the position as the largest amount of tax benefit that it is greater than a 50% likelihood of being realized upon ultimate settlement. If the benefit does not meet the more likely than not criteria for being sustained on its technical merits, no benefit will be recorded. Uncertain tax positions that relate only to timing of when an item is included on a tax return are considered to have met the recognition threshold.

DT Midstream leases assets under an operating lease for a pipeline which commenced in December 2018. The lease is comprised of fixed payments with a remaining term of 16 years. The operating lease does not have renewal provisions or options to purchase the assets at the end of the lease and does not have termination for convenience provisions. The lease term extends to the end of the estimated economic life of the leased assets, thereby resulting in no residual value.
A lease is deemed to exist when DT Midstream has provided other parties with the right to control the use of identified property, plant or equipment, as conveyed through a contract, for a certain time period and consideration received. The right to control is deemed to occur when DT Midstream has provided other parties with the right to obtain substantially all of the economic benefits of the identified assets and the right to direct the use of such assets.
Lessee
Lessee
Leases at DT Midstream are primarily comprised of equipment and buildings with terms ranging from approximately 3 to 11 years.
A lease is deemed to exist when DT Midstream has the right to control the use of identified property, plant or equipment, as conveyed through a contract, for a certain time period and consideration paid. The right to control is deemed to occur when DT Midstream has the right to obtain substantially all of the economic benefits of the identified assets and the right to direct the use of such assets.
Lease liabilities are determined utilizing a discount rate to determine the present values of lease payments. GAAP requires the use of the rate implicit in the lease when it is readily determinable. When the rate implicit in the lease is not readily determinable, the incremental borrowing rate is used. The incremental borrowing rate is based upon the rate of interest that would have been paid on a collateralized basis over similar contract terms to that of the leases. The incremental borrowing rates have been determined utilizing an implied secured borrowing rate based upon an unsecured rate for a similar time period of remaining lease terms, which is then adjusted for the estimated impact of collateral.
DT Midstream has leases with non-index-based escalation clauses for fixed dollar or percentage increases.
DT Midstream has certain leases which contain purchase options. Based upon the nature of the leased property and terms of the purchase options, DT Midstream has determined it is not reasonably certain that such purchase options will be exercised. Thus, the impact of the purchase options has not been included in the determination of right-of-use assets and lease liabilities for the subject leases.
DT Midstream has certain leases which contain renewal options. Where the renewal options were deemed reasonably certain to occur, the impacts of such options were included in the determination of the right of use assets and lease liabilities.
DT Midstream has agreements with lease and non-lease components, which are generally accounted for separately. Consideration in a lease is allocated between lease and non-lease components based upon the estimated relative standalone prices.
Property, Plant, and Equipment Property, Plant, and EquipmentProperty is stated at cost and includes construction-related labor, materials, and overhead. Expenditures for maintenance and repairs are charged to expense when incurred. DT Midstream's property, plant and equipment is depreciated over its estimated useful life using the straight-line method.
Intangible Assets and Long-Lived Assets
Intangible Assets
Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. See Note 6, "Property, Plant, and Equipment and Intangible Assets" to the Consolidated Financial Statements.
Long-Lived Assets
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds the expected undiscounted future cash flows generated by the asset, an impairment loss is recognized resulting in the asset being written down to its estimated fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell.
Depreciation and Amortization Depreciation and AmortizationDepreciation and amortization is related to Property, plant and equipment and Customer relationships and other intangible assets, net, used in our transportation, storage and gathering businesses.
