As filed, collateral included
1.26% collateralIGM's filing lists 298 positions including 1.26% of net assets in securities-lending cash collateral. Counted as filed the fund reads 25.8 effective holdings with a top ten of 55.57%; on its own investments — the figure above — it reads 25.9 with a top ten of 55.57%. 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 IGM'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, $140m was out to 22 borrowers, 1.31% of net assets. The largest, UBS AG, held 34.6% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| UBS AG | $49m | 34.6% |
| JP MORGAN SECURITIES LLC | $21m | 15.0% |
| CITIGROUP GLOBAL MARKETS INC. | $18m | 12.7% |
| GOLDMAN SACHS & CO. | $9m | 6.8% |
| MORGAN STANLEY & CO LLC | $8m | 5.8% |
Cash collateral reported against the loan: 1.26% of net assets, 96.1% 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 IGM has filed, with each borrower: IGM.json · all funds.

Derivative exposure and counterparties
as of 2026-06-30A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $10.71B. Notional of an interest-rate or currency swap is not equity exposure.
