Remaining Performance Obligations

Our remaining performance obligations, which is the equivalent of our backlog, represent the expected transaction price allocated to our contracts that we expect to recognize as revenue in future periods when we perform under the contracts. These remaining obligations exclude unexercised contract options and potential orders under ordering-type contracts such as Indefinite Delivery, Indefinite Quantity contracts. At March 30, 2019, we had $9.7 billion in remaining performance obligations of which we expect to recognize revenues of approximately 70% through 2020, an additional 23% through 2022, and the balance thereafter.

Assets and liabilities related to our contracts with customers are reported on a contract-by-contract basis at the end of each reporting period. At March 30, 2019, contract assets and contract liabilities totaled $477 million and $927 million, respectively. At December 29, 2018, contract assets and contract liabilities totaled $461 million and $974 million, respectively. During the first quarter of 2019, we recognized $311 million in revenues that were included in the contract liability balance at December 29, 2018.
