Include all actual fee-paying, discretionary portfolios in composites for a minimum of five years or since firm or composite inception. After presenting five years of compliant data, the firm must add annual performance each year going forward up to a minimum of ten years.

这句话前半句我看懂了，就是要上报adopt GIPS前的至少五年的数据。后半句那个10年到底是什么意思，有人能解释一下吗？
