As filed, collateral included
3.84% collateralIJH's filing lists 407 positions including 3.84% of net assets in securities-lending cash collateral. Counted as filed the fund reads 202.1 effective holdings with a top ten of 10.85%; on its own investments — the figure above — it reads 287.4 with a top ten of 7.73%. 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.

Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of IJH's own filings, 84 months on record. Not computed here and not from a price feed.
Cross-checked against a series computed separately from prices: median difference 0.05 percentage points over 84 months, which is roughly the distributions. Every month with the filing it came from: IJH.json · all funds.
Who borrows IJH'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, $4.7bn was out to 31 borrowers, 3.79% of net assets. The largest, JP MORGAN SECURITIES LLC, held 22.4% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| JP MORGAN SECURITIES LLC | $1.1bn | 22.4% |
| CITIGROUP GLOBAL MARKETS INC. | $626m | 13.3% |
| BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED | $427m | 9.1% |
| BofA Securities, Inc. | $369m | 7.8% |
| GOLDMAN SACHS INTERNATIONAL | $344m | 7.3% |
Cash collateral reported against the loan: 3.84% of net assets, 101.4% 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 IJH has filed, with each borrower: IJH.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-30403 positions became 402: 9 added (2.9% of the fund at the later date), 10 dropped (2.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 10.3%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Asset categories and pricing
as of 2026-06-3096.16% equity, 3.83% short-term investment as filed; 100.0% carried at a quoted market price (fair-value level 1). Categories and levels are the filer's; what a low level-1 share does and does not mean is in the measure's page.
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 $124.33B. Notional of an interest-rate or currency swap is not equity exposure.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| HSBC BANK PLC | $0M | 0% |
| Merrill Lynch International | $0M | 0% |
| BNP PARIBAS | $0M | 0% |
| JPMORGAN CHASE BANK, NATIONAL ASSOCIATION | $0M | 0% |
Financing leg as filed: the fund pays OVERNIGHT BANK FUNDING RATE + 0.4% on $1M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.

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.
