About these numbers
Gross asset value is what the manager reports holding in the fund at each fiscal year-end, on SEC Form ADV, Schedule D. It includes the GP’s own commitment and is before carried interest, so it is not the LPs’ net return, and it does not show cash already distributed. A fall in value can mean distributions, markdowns or both. Fund size is the amount sold reported on Form D, which for some funds reflects only a first close. Private fund ID 805-5732473377.
