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 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 ($82.78B), not of the fund’s net assets ($82.48B). The two differ by cash, derivatives filed with no market value, and rounding.
