Who borrows SCHZ'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, $15m was out to 10 borrowers, 0.14% of net assets. The largest, CITIGROUP GLOBAL MARKETS INC., held 33.6% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| CITIGROUP GLOBAL MARKETS INC. | $5m | 33.6% |
| JP MORGAN SECURITIES LLC | $5m | 30.8% |
| BofA Securities, Inc. | $3m | 18.8% |
| NOMURA SECURITIES INTERNATIONAL INC. | $725,188 | 4.8% |
| BMO Capital Markets | $653,685 | 4.4% |
Cash collateral reported against the loan: 0.15% of net assets, 106% 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 SCHZ has filed, with each borrower: SCHZ.json · all funds.

Half the sum of all weight changes, a turnover proxy: 10.0%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.
