Read this figure with the following in mind

11.1% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 78.2

The figure below is what the filing says, published unchanged. What it may not do is sit beside a plain long-only fund and be read as the same quantity. How comparability is decided.

As filed, collateral included

11.07% collateral

IGIB'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

2026-05-31

The 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.

BorrowerOn loanShare 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 → 2026-05-31

3,022 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. Every filing of IGIB compared this way, as a feed: changes.xml · all funds: filings received.

  • 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.
