BAILLIE GIFFORD & CO holds a position with no prior filing to compare against, so its change is unknown rather than zero — and it is left out of the totals above.

From 13F filings, which cover institutions managing over $100m and are filed up to 45 days after the quarter ends — so this is a considered position, not a live one, and it is not the whole shareholder register.
