Based on the fund's own SEC Form N-PORT monthly flow disclosures (Item C.9 "Flow Information") — sales minus redemptions, reinvested distributions excluded. This is a different, independent metric from the "Net flows" estimate above (which is derived from daily shares-outstanding changes). SEC N-PORT filing lag is up to ~60 days; the most recent month/quarter may not yet be fully reflected.
