(1)Includes revenues earned from foreign military sales through the U.S. government.Earnings in Equity Method InvestmentsOur share of income or loss from equity method investments was $40, $86 and $90, primarily in our BDS segment, for the years ended December 31, 2021, 2020 and 2019, respectively.BacklogOur total backlog includes contracts that we and our customers are committed to perform. The value in backlog represents the estimated transaction prices on performance obligations to our customers for which work remains to be performed. Backlog is converted into revenue, primarily based on the cost incurred or at delivery and acceptance of products, depending on the applicable revenue recognition model.Our backlog at December 31, 2021 was $377,499. We expect approximately 17% to be converted to revenue through 2022 and approximately 74% through 2025, with the remainder thereafter. There is significant uncertainty regarding the timing of when backlog will convert into revenue due to 787 production issues and associated rework, timing of 737 MAX delivery resumption in China, timing of entry into service of the 777X, 737 MAX 7 and/or 737 MAX 10, and COVID-19 impacts.
