The Australian Prudential Regulation Authority issued Prudential Standard GPS 112 to establish minimum requirements for the size and composition of the capital base for general insurers and Level 2 insurance groups. The standard mandates that regulated institutions classify capital instruments into Common Equity Tier 1, Additional Tier 1, or Tier 2 categories based on strict eligibility criteria and loss-absorption characteristics. It further requires specific regulatory adjustments to determine the capital base and imposes minimum thresholds relative to prescribed capital amounts and prudential capital requirements.
