Large cash flow - “level at which the firm determines that an external cash flow may distort performance if the portfolio is not valued.” A large CF should be less than a significant CF and the portfolio stays in the composite. The only effect is during the composite performance calculation where any portfolio with a large CF is valued on that date. Large CF policies are mandatory.
Significant cash flow - “level at which the firm determines that a client-directed external cash flow may temporarily prevent the firm from implementing the composite strategy, thereby causing the portfolio to no longer be representative of the composite strategy.” A significant CF policy is optional, the level should be higher than a large CF, and the portfolios are temporarily removed from the composite.
