your assumptions on the 4 BOC 737's are wrong. I would suggest that
VB raised nothing by selling these aircraft as one was not "owned" but rather financed via some other bank - they might have realised a few $$$ but deposits on leases have to be paid too which are held until the aircraft are handed back. The other 3 are simply
VB handing over their purchase rights to BOC as lessee.
VB probably used the deposits held by Boeing as the deposits for the leases. These deals are done all the time all over the world. Typically airlines including QF have a mix of leased and "owned" [meaning funded by some bank consortium] aircraft. Not many pay cash ever...
