i long ago asked mgmt why that next level isn't given and have been told the same thing every time i asked there is a cost difference that they pay for this service from memory it runs approx 7k per year 7k that in mgmt's eyes is better spent elsewhere .. again calls into EXPO can get this info answered .. if interested They could release the info on the bottom of their filings or on their website and guess what...it is free. the cost issue is null and void.
