For the years ended December 31, 2021, 2020 and 2019, White Mountains received dividend and income distributions from equity method eligible investments of $56.2 million, $95.0 million and $14.8 million, which were recorded within net investment income in the consolidated statement of operations. As a result of the 2019 MediaAlpha Transaction, White Mountains deconsolidated MediaAlpha as of February 26, 2019. Upon deconsolidation, White Mountains’s investment in MediaAlpha met the criteria to be accounted for under the equity method or under the fair value option. White Mountains elected the fair value option. White Mountains’s consolidated statement of comprehensive income and its segment disclosures include MediaAlpha’s results of operations for the period from January 1, 2019 through February 26, 2019. Following the MediaAlpha IPO, White Mountains’s investment in MediaAlpha is accounted for at fair value based on the publicly traded share price of MediaAlpha’s common stock and White Mountains presents its investment in MediaAlpha as a separate line item on the balance sheet. See Note 2 — “Significant Transactions”. For the period from February 26, 2019 to December 31, 2019 and for the year ended December 31, 2020, MediaAlpha was considered a significant subsidiary. For the period from February 26, 2019 to December 31, 2019, MediaAlpha’s total revenues, total expenses, and net income were $359.2 million, $336.3 million, and $22.9 million. The following tables present summarized financial information for MediaAlpha as of December 31, 2021 and 2020 for the years ended December 31, 2021, 2020, and 2019:
