Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of CORP's own filings, 84 months on record. Not computed here and not from a price feed.
Cross-checked against a series computed separately from prices: median difference 0.12 percentage points over 84 months, which is roughly the distributions. Every month with the filing it came from: CORP.json · all funds.
Who borrows CORP'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, $5m was out to 3 borrowers, 0.30% of net assets. The largest, BARCLAYS CAPITAL INC., held 48.9% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS CAPITAL INC. | $2m | 48.9% |
| GOLDMAN SACHS & CO. | $1m | 27.9% |
| RBC Capital Markets LLC | $1m | 23.2% |
Cash collateral reported against the loan: 0.31% of net assets, 101.8% 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 CORP has filed, with each borrower: CORP.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-301,527 positions became 1,457: 91 added (13.4% of the fund at the later date), 161 dropped (11.8% at the earlier date). Half the sum of all weight changes, a turnover proxy: 16.9%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.
