Segment Reporting [Abstract]

Segments

Segments:

In the first quarter of 2024, the company made changes to its organization structure and management system to better align its portfolio with the market, increase transparency and improve segment comparability to peers. These changes did not impact the company's Consolidated Financial Statements, but did impact its reportable segments. Due to the removal of certain components of segment profitability, as described below, the company also updated the title of its segment performance metric from pre-tax income from continuing operations to segment profit.

The following table displays the segment updates:

Reportable Segment Change	Resulting Segment Implications
The Weather Company asset divestiture	-	Software Segment
	+	Other-divested businesses
Security Services realignment	-	Software Segment
	+	Consulting Segment
Removal of stock-based compensation and net interest allocations from segment profitability	-	Software Segment, Consulting Segment, Infrastructure Segment, Financing Segment (1)
	+	Other

(1) Presentation of interest for the Financing Segment did not change.

The following tables reflect the results of continuing operations of the company’s segments consistent with the management and measurement system utilized within the company and have been recast for the prior-year periods to reflect the company's segment changes described above. These results are used by the chief operating decision maker, both in evaluating the performance of, and in allocating resources to, each of the segments.
