Who borrows JPXN's shares
2026-06-30The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $231,507 was out to 3 borrowers, 0.17% of net assets. The largest, STATE STREET BANK & TRUST COMPANY, held 61.6% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| STATE STREET BANK & TRUST COMPANY | $142,612 | 61.6% |
| BofA Securities, Inc. | $66,777 | 28.8% |
| GOLDMAN SACHS & CO. | $22,118 | 9.6% |
Cash collateral reported against the loan: 0.18% of net assets, 104.5% 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 JPXN has filed, with each borrower: JPXN.json · all funds.

2026-03-31 → 2026-06-30395 positions became 392: 2 added (0.0% of the fund at the later date), 5 dropped (0.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 11.3%.

Derivative exposure and counterparties
as of 2026-06-30A 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 $134M. Notional of an interest-rate or currency swap is not equity exposure.
