The increase in deferred revenue is primarily due to deferrals outpacing revenue recognized in the period, specifically reflecting growth in CNA’s business. Approximately $886 million of revenues recognized during the year ended December 31, 2018 were included in deferred revenue as of January 1, 2018.

There were no adjustments to deferred costs recorded for the year ended December 31, 2018.

Performance obligations – As of December 31, 2018, approximately $12.4 billion of estimated operating revenues is expected to be recognized in the future related to outstanding performance obligations. The balance relates primarily to revenues for transportation and storage of natural gas and NGLs at Boardwalk Pipeline and non-insurance warranty services at CNA. Approximately $2.1 billion will be recognized during 2019, $1.7 billion in 2020 and the remainder in following years. The actual timing of recognition may vary due to factors outside of the Company’s control. The Company has elected to exclude variable consideration related entirely to wholly unsatisfied performance obligations and contracts where revenue is recognized based upon the right to invoice the customer. Therefore, the estimated operating revenues exclude contract drilling dayrate revenue at Diamond Offshore and interruptible service contract revenue at Boardwalk Pipeline.
