Who borrows PABU's shares
2026-02-28The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-02-28, $4m was out to 4 borrowers, 0.16% of net assets. The largest, BofA Securities, Inc., held 46.7% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BofA Securities, Inc. | $2m | 46.7% |
| CITIGROUP GLOBAL MARKETS INC. | $1m | 28.3% |
| GOLDMAN SACHS & CO. | $906,759 | 24.7% |
| MORGAN STANLEY & CO LLC | $10,847 | 0.3% |
Cash collateral reported against the loan: 0.16% of net assets, 99.6% 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 PABU has filed, with each borrower: PABU.json · all funds.
Since the previous filing
2026-02-28 → 2026-05-31136 positions became 133: 2 added (0.0% of the fund at the later date), 5 dropped (1.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 8.5%.

Derivative exposure and counterparties
as of 2026-05-31A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $2.64B. Notional of an interest-rate or currency swap is not equity exposure.
