As filed, collateral included
6.03% collateralSMLF's filing lists 911 positions including 6.03% of net assets in securities-lending cash collateral. Counted as filed the fund reads 166 effective holdings with a top ten of 12.99%; on its own investments — the figure above — it reads 418.6 with a top ten of 7.57%. 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.

The filing reports no cash collateral position against this loan. Collateral taken in a form the fund does not hold as a position does not appear in N-PORT, so this is silence rather than absence.

100.0% of SMLF is carried at a quoted market price (fair-value level 1). Categories and levels are the filer's, from Form N-PORT; what a low level-1 share does and does not mean is in the measure's page.
Derivative exposure and counterparties
as of 2026-04-30A 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 $3.63B. Notional of an interest-rate or currency swap is not equity exposure.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| HSBC BANK PLC | $9M | 0.26% |
| Goldman Sachs International | $7M | 0.21% |
| JPMORGAN CHASE BANK, NATIONAL ASSOCIATION | $7M | 0.19% |
| BNP PARIBAS | $1M | 0.04% |
Financing leg as filed: the fund pays OBFR01 + 0.388% on $25M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
