SIGNIFICANT ACCOUNTING POLICIES

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.

We regularly monitor the credit quality of our financing receivables by reviewing counterparty credit quality indicators and monitoring for triggering events, such as a credit rating downgrade or bankruptcy. We have 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, 2023. As of December 31, 2023, the Notes receivable — related party of $4 million, which originated prior to 2021, was classified as internal grade 1. There are no notes receivable on nonaccrual status and no past due financing receivables as of December 31, 2023.

Notes receivable are typically considered delinquent (past due) when payment is not received for periods ranging from 60 to 120 days. We cease 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 contractual principal or interest amounts due will not be collected. In determining an allowance for expected credit losses for or the write off of notes receivable, we consider 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.

We 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, we 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. We maintain no continuing involvement with the note receivable.

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 each of the years ended December 31, 2023, 2022 and 2021. 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, 2023 or 2022.

The following table presents a roll-forward of the activity for the notes receivables' allowance for expected credit loss. The balance, if any, is shown as a deduction from the notes receivables' 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. 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. For the year ended December 31, 2021, general corporate expense allocations from DTE Energy of $32 million, including $20 million of 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. Effective July 1, 2021, with the completion of the Separation, we no longer received corporate allocations from DTE Energy.

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.
