The Board invites comment on an interim final rule that amends the capital plan and stress test rules to require a bank holding company with total consolidated assets of $50 billion or more to estimate its tier 1 common ratio using the methodology currently in effect in 2013 under the existing capital guidelines (not the rules as revised on July 2, 2013). The interim final rule also clarifies when a banking organization would estimate its minimum regulatory capital ratios using the advanced approaches for a given capital plan and stress test cycle and makes minor, technical changes to the capital plan rule.
