Who borrows PABU's shares

2026-02-28

The 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.

BorrowerOn loanShare 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 → 2026-05-31

136 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%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of PABU compared this way, as a feed: changes.xml · all funds: filings received.

100.0% of PABU is carried at a quoted market price (fair-value level 1). Categories and levels are the filer's, from Form N-PORT; what a low level-1 share does and does not mean is in the measure's page.

Derivative exposure and counterparties

as of 2026-05-31

A 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.
