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 and decreased revenue by $482 million in the three months ended June 30, 2019 and 2018.

Contract liabilities in our Automotive segments consist primarily of maintenance, extended warranty and other service contracts. We recognized revenue of $469 million and $902 million related to contract liabilities in the three and six months ended June 30, 2019 and $402 million and $785 million in the three and six months ended June 30, 2018. We expect to recognize revenue of $846 million in the six months ending December 31, 2019 and $689 million, $403 million and $465 million in the years ending December 31, 2020, 2021 and thereafter related to contract liabilities at June 30, 2019.
