Boeing shares fell Thursday after a report that regulators are investigating accounting practices for two of its jetliners.
The Securities and Exchange Commission is looking into the aerospace giant's projections about the long-term profitability of its well-known 787 Dreamliner and 747 jumbo aircraft, Bloomberg reported, citing people with knowledge of the matter. The probe surrounds so-called program accounting, which allows Boeing to spread upfront costs of manufacturing over a longer period of time.
"We typically do not comment on media inquiries of this nature," Boeing told CNBC.
Its shares closed nearly 7 percent lower Thursday.
