There is no statistics. If you talk to expats who are about to
be sent back to their home countries, you will get an idea.
Specifically if you want to research on this topic, go meet ppl in
clubs like the American Club, The French Business Association, talk
to mothers picking up kids at Australian International School or
the United World College, or talk to the Japs at SICC or TMCC (not
many of them there now), you will get a better picture.

Expats here refer to mostly the angmoh, they come here with big
fat benefits, want to stay as long as possible but there is no
intention to stay here. I believe these expats are also called FT,
but when we complain about FT, we are only complaining about those
who came from China, Philippines, India or Sri Lanka. Actually,
these angmoh expats are the higher costs in companies. The Asian FT
are usually not called expats and their packages are much much
lower than those from the western countries.

I fully understand the plight of those retrenched, I was
retrenched once. It is not just in GLC but all companies here,
foreigners are replacing singaporean. If we were replaced by ppl,
local or FT because they are more capable, or at least cheaper, we
probably gam guan. But if you were replaced by some chao angmoh,
sent from HQ, don't know any asian culture and languages, only
doing something locals can do as well or better, and at much higher
costs, how do you feel? 
It is therefore annoying to hear ppl say that many expats decide
just to tahan for the time being.
