According to the most recent accreditation agreement:
"Registrar shall maintain in force commercial general liability insurance or similar liability insurance as specified by ICANN with policy limits of at least US$500,000 covering liabilities arising from Registrar's registrar business during the Term of this Agreement."
It would be interesting to find out what insurance company would provide such a service (meaning $150,000,000 in potential liability being 300 x US$500,000) for a set of 300 newly-registered companies, and under what legal/financial conditions...
Just a curiosity, since namebright is supposed to give the details to ICANN only, and ICANN does not publish such reports
