Anton,
I presume you are referring to the NCA FRI scheme, which as you say, was initially planned to run for 3 years. I think the original post was referring the Officers FRI scheme.
Just to be aware though, that as it said in last years AFPRB, the scheme will run for an initial 3 years, but the amounts can/will be reviewed each year, in response to manning levels etc. You never know, if not enough people take up the FRI the levels might be increased ............ or not
