Since Barbados is at times considered an expensive place to conduct business, the treaties are mainly a measure to provide some savings to international businesses operating in Barbados.

Since a primary design specification of x86 microprocessors is that they are fully backwards compatible with software written for all x86 chips before them, the 286 chip was made to start in ' real mode ' – that is, in a mode which turned off the new memory protection features, so that it could run operating systems written for the 8086 and the 80186.
