Where these figures come from
A holding is a fund's common or preferred share of a company that is not listed: valued with unobservable inputs (fair value level 3) and placed privately (a restricted security, or PP in its title), never a right left from a takeover, an escrow, or a vehicle that holds such shares. A company that funds hold as a listed share in the same data set is public and left out. Rows are joined into a company by its name, its share class and legal form cut off. Each fund values its shares itself, every quarter, so two funds can value one share differently.
Each row is a fund's latest public Form N-PORT. The other private companies US funds hold are on the list of private companies.
