ITEM 8.01 OTHER EVENTS

As noted in our Form 10-K and Form 10-Q filings, we lease commercial aircraft to
domestic  airlines through leveraged lease  transactions,  including leases with
Delta Air Lines Inc.  (Delta)  and  Northwest  Airlines  Corp.  (Northwest).  On
September  14,  2005,   Delta  and  Northwest  filed  voluntary   petitions  for
reorganization  under  Chapter 11 of the United  States  Bankruptcy  Code.  As a
result of  these bankruptcy  filings,  in the third quarter we expect to record,
within "Other income  (expense)",  a pretax charge of approximately  $90 million
relating to our  investment in these  leases,  which would have an estimated net
income impact of approximately $50 million.
