As filed, collateral included
12.69% collateralHYG's filing lists 1,323 positions including 12.69% of net assets in securities-lending cash collateral. Counted as filed the fund reads 58.3 effective holdings with a top ten of 15.89%; on its own investments — the figure above — it reads 907.5 with a top ten of 3.57%. 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 HYG's shares
2026-05-31The 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 29 borrowers, 12.17% of net assets. The largest, DEUTSCHE BANK SECURITIES INC, held 16.9% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| DEUTSCHE BANK SECURITIES INC | $331m | 16.9% |
| BARCLAYS BANK PLC | $287m | 14.6% |
| RBC Capital Markets LLC | $195m | 10.0% |

Cash collateral reported against the loan: 12.69% of net assets, 104.3% 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 HYG has filed, with each borrower: HYG.json · all funds.

2026-02-28 → 2026-05-311,342 positions became 1,322: 93 added (6.2% of the fund at the later date), 113 dropped (6.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 12.8%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

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.
