## 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.
