discretionary：manager is able to implement intended investment strategy
客户施加的constraint要material重大且pertinent相关：non-discretionary,不进入业绩衡量范围
自有资金（seed money）可放入non-fee-paying portfolio的composite
all actual, fee-paying, discretionary segregated accounts must be included in at least one composite
descretionary segregated accounts that are non-fee paying may be included in composite
pooled funds must be included in any composite for which they meet definition
if strategy is offered as pooled fund and segregated account, they must be in composite for that strategy
portfolio不能在composite之间切换，除非客户主动修改委托目标、策略，历史业绩不追溯调整
若发生significant CF，portfolio可被暂时移出composite，也可以使用临时账户消除CF影响
若composite有最低资产要求，当portfolio达不到要求应被视为non-discretionary
