Seeing it listed like that, it's easy to spot where it appears in Boeing's current financial statements (https://investors.boeing.com/investors/financial-reports/default.aspx https://investors.boeing.com/investors/financial-reports/def...). From 2019Q3-10Q, the 787 'inventory' asset includes about $20b in deferred production expensing (plus $2.2b in tooling), and the 737MAX inventory contains $1.5b in deferred production and $0.5b in tooling. Combined, that represents a significant fraction of Boeing's $132b in total (gross) assets.
