Who borrows PFF's shares

2026-06-30

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $43m was out to 10 borrowers, 0.33% of net assets. The largest, MORGAN STANLEY & CO LLC, held 50.2% of it.

BorrowerOn loanShare of the loan
MORGAN STANLEY & CO LLC $22m 50.2%
JP MORGAN SECURITIES LLC $13m 31.3%
UBS SECURITIES LLC $5m 10.5%
BofA Securities, Inc. $2m 3.7%
GOLDMAN SACHS & CO. $1m 2.7%

Cash collateral reported against the loan: 0.33% of net assets, 100.6% 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 PFF has filed, with each borrower: PFF.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

456 positions became 456: 10 added (3.2% of the fund at the later date), 10 dropped (1.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 6.7%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of PFF compared this way, as a feed: changes.xml · all funds: filings received.
