IGLB reports 3,836 holdings and behaves like 1905.3 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-05-31. The fact sheet publishes the first number; this page computes the second, and traces it across 27 quarters of filings.

Measured concentration

Read this figure with the following in mind

10.8% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 81.5

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

10.84% collateral

IGLB's filing lists 3,837 positions including 10.84% of net assets in securities-lending cash collateral. Counted as filed the fund reads 81.5 effective holdings with a top ten of 13.27%; on its own investments — the figure above — it reads 1905.3 with a top ten of 2.64%. 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 IGLB'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, $277m was out to 21 borrowers, 10.51% of net assets. The largest, GOLDMAN SACHS & CO., held 27.3% of it.

BorrowerOn loanShare of the loan
GOLDMAN SACHS & CO. $76m 27.3%
JP MORGAN SECURITIES LLC $61m 22.2%
BARCLAYS BANK PLC $50m 17.9%
BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED $25m 9.2%
Wells Fargo Securities LLC $16m 5.7%

Cash collateral reported against the loan: 10.84% of net assets, 103.1% 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 IGLB has filed, with each borrower: IGLB.json · all funds.

Since the previous filing

2026-02-28 → 2026-05-31

3,828 positions became 3,836: 71 added (2.8% of the fund at the later date), 63 dropped (1.2% at the earlier date). Half the sum of all weight changes, a turnover proxy: 8.7%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of IGLB compared this way, as a feed: changes.xml · all funds: filings received.
