CONTRACT AND OTHER DEFERRED ASSETS, CONTRACT LIABILITIES AND DEFERRED INCOME & PROGRESS COLLECTIONS CONTRACT AND OTHER DEFERRED ASSETS, CONTRACT LIABILITIES AND DEFERRED INCOME & PROGRESS COLLECTIONS
Contract assets (liabilities) and other deferred assets (income), on a net basis, decreased the net liability position by $187 million for the six months ended June 30, 2026, primarily due to decreases in long-term service agreement liabilities of $202 million. In aggregate, the net liability for long-term service agreements decreased primarily due to revenue recognized of $5,468 million, partially offset by billings of $5,208 million and net unfavorable changes in estimated profitability of $42 million driven by quarterly updates to contract margins, including a reversal of $118 million of tariff-related charges taken in the six months ended June 30, 2025, primarily in CES. Revenue recognized for contracts included in a liability position at the beginning of the year were $4,775 million and $3,892 million for the six months ended June 30, 2026 and 2025, respectively.

(a) Includes contract fulfillment costs for engineering and development incurred prior to production for equipment production contracts, primarily within our Defense & Propulsion Technologies (DPT) segment, which are amortized ratably over each unit produced. We assess the recoverability of these costs and if we determine the costs are no longer probable of recovery, the asset is impaired. The most significant program relates to DPT contracts for the Boeing 777X aircraft, which will be amortized once entered into service.
(b) Includes amounts due from customers within our CES segment for the sales of engines, spare parts and services, which we collect through fixed or usage-based billings from the sale of spare parts and servicing of equipment under long-term service agreements.

Progress collections increased $275 million in the six months ended June 30, 2026, primarily due to collections received in excess of liquidations at CES.
