This book is the iShares complex. It moves when authorized participants create and redeem ETF shares — visible daily in a fund's shares outstanding — and when an index reconstitutes. That is a different driver from BlackRock Institutional Trust Company, which runs the same index strategies as collective investment trusts and separate accounts for retirement plans, on a plan sponsor's timetable rather than the market's. Same portfolio team, same stewardship team voting the shares; the split is the client vehicle, not the investment decision, which is why some reports combine the two under this entity. Worth keeping apart anyway: a position can move in one book and not the other, and which one moved is the useful fact. BlackRock reports them as separate books — of the 8,204 holdings lines naming one of these two entities on BlackRock, Inc.'s Q2 2026 13F, none named both.
