Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill Disclosure [Text Block] | Goodwill The following presents our goodwill balance allocated by segment as of September 30, 2024:
(in millions) |  | Columbia Operations |  | NIPSCO Operations |  | Corporate and Other |  | Total
Goodwill |  | $ | 1,468.1 |  |  | $ | 17.8 |  |  | $ | — |  |  | $ | 1,485.9 |
For our annual goodwill impairment analysis performed as of May 1, 2024, we completed a quantitative "step 1" fair value measurement of our reporting units with a goodwill balance. This analysis incorporated the latest available income statement and cash flow projections. We also incorporated other significant inputs to our fair value calculations, including discount rate and market multiples, to reflect current market conditions. The step 1 analysis performed indicated that the fair value of each reporting unit that is allocated goodwill exceeded its carrying value. As a result, no impairment charge was recorded as of the May 1, 2024 test date. While our annual goodwill impairment test was performed with a valuation date of May 1, 2024, we continue to monitor events and circumstances that could indicate that it is more likely than not that the fair value of our reporting units is less than the reporting unit carrying value. At September 30, 2024, we assessed events including, but not limited to, general economic conditions, access to capital, developments in the equity and credit markets, the impact on NiSource's share price, the availability and cost of materials and labor, the impact on revenue and cash flow, and regulatory and political activity. The results of this assessment indicated that it was not more likely than not that the fair values of our reporting units were less than their respective carrying values at September 30, 2024.
