Notes to Financial Statements
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	11. Dispositions: On February 1, 2020, the sale of the aerial imagery sourcing group was completed. We contributed assets related to the disposed business, including cash of $63.8 million, in exchange for a non-controlling 35.0% ownership interest in a nonpublic company, Vexcel. We determined the fair value of the securities associated with the non-controlling ownership interest in Vexcel with the assistance of valuations performed by third-party specialists, including the discounted cash flow analysis and estimates made by management. The securities were concluded not to have a readily determinable fair value and did not qualify for the practical expedient to estimate fair value. The contributed assets approximated the fair value of the equity securities related to the non-controlling ownership interest; therefore, there was no gain or loss recorded in conjunction with this disposition for the year ended December 31, 2020. On February 14, 2020, the sale of the compliance background screening business was completed for net cash proceeds of $23.1 million. A gain of $15.9 million was included in "Other operating (income) loss" within our accompanying consolidated statements of operations for the year ended December 31, 2020. In the first quarter of 2020, our data warehouse business within the Financial Services segment qualified as assets held for sale and was sold on March 1, 2020. We recorded a gain of $3.5 million in "Other operating (income) loss" within our accompanying consolidated statements of operations for the year ended December 31, 2020.
