Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill | GOODWILL DT Midstream has goodwill that resulted from business combinations. The carrying value of goodwill is evaluated for impairment on an annual basis or whenever events or circumstances indicate that the value of goodwill may be impaired. We performed our prior year annual impairment test as of October 1, 2022 and determined that the estimated fair value of each reporting unit exceeded its carrying value, and no impairment existed. No additions, impairments or other changes occurred during the three months ended March 31, 2023. The following is the summary of the carrying amount of goodwill:
| March 31, |  | December 31,
| 2023 |  | 2022
| (millions)
Pipeline | $ | 53 |  |  | $ | 53 |
Gathering | 420 |  |  | 420 |
Total | $ | 473 |  |  | $ | 473 |
While we believe the estimates and assumptions in the estimated fair value are reasonable, the actual results may differ from projections. To the extent projected results or cash flows are revised downward, the reporting unit may be required to write down all or a portion of its goodwill, which would adversely impact our earnings. If current expectations of future long-term growth are not met or market factors outside of our control change, such as U.S. Treasury Rates, a sustained further decline in our market capitalization, or a further decline in midstream industry transaction multiples, this may lead to a goodwill impairment in the future.
