As filed, collateral included
3.43% collateralMDYG's filing lists 246 positions including 3.43% of net assets in securities-lending cash collateral. Counted as filed the fund reads 123.7 effective holdings with a top ten of 16.54%; on its own investments — the figure above — it reads 144.6 with a top ten of 14.43%. 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 MDYG'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, $231m was out to 21 borrowers, 7.89% of net assets. The largest, BARCLAYS BANK PLC, held 54.9% of it.
| Borrower | On loan | Share of the loan |

Cash collateral reported against the loan: 3.43% of net assets, 43.5% 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 MDYG has filed, with each borrower: MDYG.json · all funds.
