Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of FBT's own filings, 84 months on record. Not computed here and not from a price feed.

Who borrows FBT's shares
2026-03-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-03-31, $176,735 was out to 1 borrower, 0.01% of net assets.
| Borrower | On loan | Share of the loan |
|---|---|---|
| JP MORGAN SECURITIES LLC | $176,735 | 100.0% |
Cash collateral reported against the loan: 0.01% of net assets, 128.5% 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 FBT has filed, with each borrower: FBT.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-3031 positions became 31: 2 added (5.7% of the fund at the later date), 2 dropped (8.2% at the earlier date). Half the sum of all weight changes, a turnover proxy: 18.2%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.
