Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Adjustments to sales incentives for previously recognized sales were insignificant during the year ended December 31, 2018.

Contract liabilities in our Automotive segments consist primarily of maintenance, extended warranty and other service contracts. We recognized revenue of $1.4 billion related to contract liabilities during the year ended December 31, 2018. We expect to recognize revenue of $1.5 billion, $509 million and $626 million in the years ending December 31, 2019, 2020 and thereafter related to contract liabilities as of December 31, 2018.
