Last news reports, their CEO says that cash bleed is approx $300M each month.

 

So maybe their $5.15B in spare cash, can last more than 1 year, on the proviso that they don' t pay aircraft installments, but this is very unlikely since probably need to pay periodic installments, cannot be pay one lump sum upon delivery, what happens if airline goes bust or declare bankrupt, the what will Airbus or Boeing do with the half built aircraft?

 

So maybe they will still need to recruit the $6.2B in MCB, maybe draw less at $3.1B if can find cheaper funding from bonds.

 

Or maybe Temasek allow the MCB drawdown to be extended by 1 year, since having that back stop seems to be allowing SIA to borrow $$$ at quite a cheap rate.
