Who borrows JCPB's shares

2019-11-30

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2019-11-30, $10,611 was out to 1 borrower, 0.03% of net assets.

BorrowerOn loanShare of the loan
CITIGROUP GLOBAL MARKETS INC. $10,611 100.0%

Cash collateral reported against the loan: 0.05% of net assets, 174.4% 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 JCPB has filed, with each borrower: JCPB.json · all funds.

Since the previous filing

2026-02-28 → 2026-05-31

2,581 positions became 2,660: 218 added (17.0% of the fund at the later date), 139 dropped (5.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 21.9%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of JCPB compared this way, as a feed: changes.xml · all funds: filings received.

10.1% of JCPB is carried at a quoted market price (fair-value level 1); 6.6% at level 3, priced from the filer's own inputs. 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 $12.44B. Notional of an interest-rate or currency swap is not equity exposure.
