A fund multiple counting cash already distributed plus the current value of everything still held, divided by the capital investors have paid in.
A fund at 0.4x DPI and 2.5x TVPI has returned forty percent of the money and is asserting the rest.
Most of an immature fund's TVPI is the manager's own valuation of assets nobody has bought. Split it into cash returned and value asserted before reading it as a result.
