- Be a company founded and majority (50.01 per cent plus) owned by South Australians.
Companies owned in part or whole by government, government agencies and organisations, and registered charities are not eligible for consideration.
Listed entities have a readily ascertainable value per security, allowing for transparent market capitalisation. For unlisted companies, valuations have been estimated using industry margin benchmarking (available from the ABS and ATO) and a consistently applied price to earnings multiple.
