Equity in Earnings (Losses) of Nonconsolidated Affiliates The Company’s share of equity in earnings of nonconsolidated affiliates was $975 million in 2021 , compared with equity losses of $18 million in 2020 and $94 million in 2019 . The equity earnings improvement in 2021 compared with 2020 was primarily due to margin expansion at Sadara driven by broad-based price increases, strong MEG prices at the Kuwait joint ventures and improved elastomer and polyethylene margins at the Thai joint ventures. In 2020 , equity losses decreased compared with 2019 primarily due to lower equity losses from Sadara, driven by improved industry supply and demand dynamics in the third and fourth quarters of 2020, which were partially offset by lower equity earnings from the Kuwait joint ventures due to lower monoethylene glycol prices. See Note 12 to the Consolidated Financial Statements for additional information on the Company’s evaluation of its equity method investment in Sadara for other-than-temporary impairment in 2019.
