Answer:
Most likely a Government sponsored Insurance Pool Is actaully made up of City or county government and school districts. Instead of being insured by one large insurance company, they all put money in to this "pool". So that when the end of the year comes and they find out they have extra money left over in this pool from not having as many worker comp issues,etc.. they get the money back instead of the insurance company keeping that money. That might not be what your looking for, but that is kind of how a gov`t pool works.. obv. there is more too it, but that is the basic idea.
