The sales of businesses and the classification of certain assets and liabilities as held for sale included cash, net of proceeds, of $62.9, $6.7 and $30.8 for the years ended 2020, 2019 and 2018, respectively, which is classified within the Other Investing Activities line in our Consolidated Statements of Cash Flows. Other – During 2020, the amounts recognized were primarily a result of gains on remeasurement of equity interest arising from a change in ownership.
