1Overlap with other funds

As filed, collateral included
22.01% collateralTAN's filing lists 34 positions including 22.01% of net assets in securities-lending cash collateral. Counted as filed the fund reads 11.6 effective holdings with a top ten of 80.35%; on its own investments — the figure above — it reads 17.6 with a top ten of 65.15%. The collateral is matched by a liability and is not a holding the fund chose; since 2026-09-18 every figure on this site sets it aside (methodology). Both numbers are in the data.

Who borrows TAN's shares
2026-05-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-05-31, $487m was out to 33 borrowers, 21.24% of net assets. The largest, BofA Securities, Inc., held 25.7% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BofA Securities, Inc. | $125m | 25.7% |
| JP MORGAN SECURITIES LLC | $81m | 16.7% |
| MORGAN STANLEY & CO LLC | $50m | 10.4% |
| STATE STREET BANK & TRUST COMPANY | $37m | 7.7% |
| Wells Fargo Bank, National Association | $33m | 6.7% |
Cash collateral reported against the loan: 22.01% of net assets, 103.6% of the amount lent. That is a floor on the collateral, not the whole of it — collateral the fund does not hold as a position is not in this filing, so a figure under 100% is not evidence of under-collateralisation. How that figure behaves across all funds. Every quarter TAN has filed, with each borrower: TAN.json · all funds.
Since the previous filing
2026-02-28 → 2026-05-3130 positions became 32: 2 added (2.1% of the fund at the later date), 0 dropped (0.0% at the earlier date). Half the sum of all weight changes, a turnover proxy: 16.4%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.
