6. REVENUE

Disaggregation of Revenue

The following tables present revenues on a disaggregated basis, in a manner that reconciles with the Company's reportable segment disclosures, for the following categories: product versus service type, customer type, contract type, and major program. The Company believes that this level of disaggregation provides investors with information to evaluate the Company’s financial performance and provides the Company with information to make capital allocation decisions in the most appropriate manner. For more information on the Company's contracts, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company's 2023 Annual Report on Form 10-K.

The following tables present revenues on a disaggregated basis:

As of September 30, 2024, the Company had $49.4 billion of remaining performance obligations. The Company expects to recognize approximately 30% of its remaining performance obligations as revenue through 2025, an additional 30% through 2027, and the balance thereafter.

Cumulative Catch-up Revenue Adjustments

The following table presents the effect of net cumulative catch-up revenue adjustments on operating income and diluted earnings per share:

The Company’s multi-year shipbuilding contracts with the U.S. Government are routinely modified as the result of unpriced change orders arising in the ordinary course of business. These anticipated changes are accounted for as contract modifications when the scope of the work has been approved and it is probable that the price will be approved. The Company recognizes variable consideration included in the transaction price for a modified contract to the extent the Company believes a significant reversal of revenue is not probable.

For the three and nine months ended September 30, 2024, no individual favorable cumulative catch-up revenue adjustment was material to the Company's unaudited condensed consolidated statements of operations and comprehensive income.

For the three months ended September 30, 2024, cumulative catch-up revenue adjustments included unfavorable adjustments of $34 million on Block IV of the Virginia class (SSN 774) submarine program, $14 million on the refueling and complex overhaul ("RCOH") of USS John C. Stennis (CVN 74), and $16 million on the construction of Enterprise(CVN 80) and Doris Miller(CVN 81) at the Company's Newport News segment. For the nine months ended September 30, 2024, no individual unfavorable cumulative catch-up revenue adjustment was material to the Company's unaudited condensed consolidated statements of operations and comprehensive income.
