考点：巴塞尔协议3对capital的定义
解析：Tier 1 capital 包括普通股权，包括留存收益（称为一级股权资本或核心一级资本）和非累计永久优先股（额外一级资本，一级资本总额的一部分）。 一级资本不包括商誉，递延所得税资产，证券化交易产生的留存收益变动，或银行信用风险产生的留存收益变动。
同时，对DB plan里的赤字部分，Tier 1 capital要进行下调，但是对盈余不会上调。
Tier 2 包含了5年及以上的次级债务，和一些优先股（比如累计优先股）等。
Tier 3被删除了。
老师这道题看的basel 3的capital的定义，解析当中第一条一级资本不包括商誉，递延所得税资产，证券化交易产生的留存收益变动，或银行信用风险产生的留存收益变动。
商誉是在basel 2当中提到的是抵扣项，其他的是哪里提到的呀
