Over here the watershed is liability, not trading on exchanges: All corporations, where at least 1 natural person is liable without limit with ***all*** his personal finances, the requirement is waved.
In all organizations where only a juristic person is liable without upper limit (therefore the risk of bankruptcy and the resulting worth has to be calculated), publishing is mandatory. Leads to some funny results: small GmbH with total gross of 65K € fined 25K €

evolution of bureocracy in action ;-)

>>Hah! Here such info can be read in a central register, where corporations above a threshold (much lower than enterprize...) have to publish their basic financial data - believed to be a security measure so that other biz can estimate the (prob)ability to be around in a few months after entering into a contract.
