from what i know, in SG, all companies must have Pte Ltd
behind.
never heard of local company that has Incorporated (Inc.)
behind.
like, companies in Indonesia all have "PT" pre-fix in front,
companies in Malaysia has "Sdn Bhd" behind, companies in Japan have
"Co." behind, companies in Britain has "LLC" behind, companies in
Holland has "B.V" behind, companies in Denmark has "AS" in
front.
