The share-class bridge is a snapshot, not history. The SEC's fund share-class file says what each class trades as today, not what it traded as at a past report date. A fund that changed ticker or converted from a mutual fund resolves to its present-day symbol for every historical month shown.

Classification look-through

Positions resolved to the master through ISIN, then rolled up through the taxonomy. 76.6% of reported value reaches a classification.

Equity · Information Technology(31)$4.50B67.4%

Not resolved to the master(30)$1.57B23.4%

Equity · Consumer Discretionary(3)$274.53M4.1%

Equity · Communication Services(3)$247.86M3.7%

Equity · Industrials(2)$69.89M1.0%

Equity · Financials(1)$22.45M0.3%

Classification covers part of the master. 5,771 of 13,106 active securities are classified. Anything unclassified is shown as its own band rather than dropped, so a look-through total that falls short of 100% is telling you about coverage, not about the fund.

Percentages are of the reported value of positions above ($6.68B), not of the fund’s net assets ($6.59B). The two differ by cash, derivatives filed with no market value, and rounding.
