OBS_VALUE: Until 2007, all private insurers had to subscribe shares of the capital of IRB (denominated nowadays IRB-Brasil Resseguros S.A.). In 2007, that obligation ended with the end of the monopoly of IRB on reinsurance. Decree No. 60,459/1967, in its Article 45, still says that all private insurers must subscribe shares of IRB's capital, but it has been tacitly revoked.
