Measured concentration

as of 2026-05-31

Read this figure with the following in mind

5.2% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 166.3

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

5.15% collateral

IGEB's filing lists 467 positions including 5.15% of net assets in securities-lending cash collateral. Counted as filed the fund reads 166.3 effective holdings with a top ten of 10.09%; on its own investments — the figure above — it reads 289.4 with a top ten of 5.51%. 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 IGEB'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, $68m was out to 16 borrowers, 4.99% of net assets. The largest, BARCLAYS BANK PLC, held 22.3% of it.

BorrowerOn loanShare of the loan
BARCLAYS BANK PLC $15m 22.3%
JP MORGAN SECURITIES LLC $14m 20.0%
RBC Capital Markets LLC $10m 14.2%
National Bank Financial Inc. $7m 10.9%
MORGAN STANLEY & CO LLC $5m 7.2%

Cash collateral reported against the loan: 5.15% of net assets, 103.3% 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 IGEB has filed, with each borrower: IGEB.json · all funds.

Since the previous filing

2026-02-28 → 2026-05-31

478 positions became 466: 65 added (14.4% of the fund at the later date), 77 dropped (12.0% 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. Every filing of IGEB compared this way, as a feed: changes.xml · all funds: filings received.
