As filed, collateral included
11.07% collateralIGIB's filing lists 2,990 positions including 11.07% of net assets in securities-lending cash collateral. Counted as filed the fund reads 78.2 effective holdings with a top ten of 12.87%; on its own investments — the figure above — it reads 1843.2 with a top ten of 1.99%. The collateral is matched by a liability and is not a holding the fund chose; since 2026-09-18 every figure on this site sets it aside (methodology). Both numbers are in the data.

Who borrows IGIB's shares
2026-05-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-05-31, $2.0bn was out to 27 borrowers, 10.73% of net assets. The largest, BARCLAYS BANK PLC, held 21% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS BANK PLC | $411m | 21.0% |
| JP MORGAN SECURITIES LLC | $287m | 14.7% |
| GOLDMAN SACHS & CO. | $196m | 10.0% |
| DEUTSCHE BANK SECURITIES INC | $173m | 8.9% |
| RBC Capital Markets LLC | $149m | 7.6% |
Cash collateral reported against the loan: 11.07% of net assets, 103.2% 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 IGIB has filed, with each borrower: IGIB.json · all funds.
Since the previous filing
2026-02-28 → 2026-05-313,022 positions became 2,989: 235 added (7.1% of the fund at the later date), 268 dropped (7.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 10.8%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Why 2,017 IWM Holdings Read as 33: Securities Lending in the Russell 2000 ETF
IWM, the iShares Russell 2000 ETF, files 2,017 holdings but our concentration measure read it as 33. The cause is a 17% cash-collateral position from securities lending, flagged in the filing itself; set it aside and the fund's own investments behave like about 840. Seventy-three funds on this site, including IJH, IJR, RSP, LQD and HYG, had the same problem. What we found, what we changed today, and what is still open.
