(7) Investments
The Company had investments accounted for using the cost method of accounting of $5 million and $91 million at December 31, 2007 and 2006,
respectively. The Company revalued its investments to their estimated fair values as of the Effective Date in accordance with SOP 90-7. Since that time, there
have been no triggering events that required the Company to evaluate any of these investments for impairment.
In the fourth quarter of 2007, United, along with certain other major air carriers, sold its interests in Aeronautical Radio, Inc. ("ARINC") to Radio
Acquisition Corp., an affiliate of The Carlyle Group. ARINC is a provider of transportation communications and systems engineering. The transaction generated
proceeds of $128 million and resulted in a pre-tax gain of $41 million.
Investments at December 31, 2007 include $91 million of the Company's previously issued EETC debt securities that the Company repurchased in 2007.
These securities remain outstanding and are classified as available-for-sale. An unrealized loss of $5 million to record these securities at fair value has been
recognized in other comprehensive income during 2007. See Note 12, "Debt Obligations," for additional information.
(8) Intangibles
As discussed in Note 10, "Segment Information," in 2006 the Company determined that it has two reporting segments that reflect the management of its
business: Mainline and United Express. See Note 2(l), "Summary of Significant Accounting Policies—Intangibles," for further information related to impairment
testing.
