Who borrows SPTL's shares

2026-03-31

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-03-31, $38m was out to 2 borrowers, 0.36% of net assets. The largest, BARCLAYS CAPITAL INC., held 99.4% of it.

BorrowerOn loanShare of the loan
BARCLAYS CAPITAL INC. $38m 99.4%
BofA Securities, Inc. $240,501 0.6%

Cash collateral reported against the loan: 0.09% of net assets, 24.9% 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 SPTL has filed, with each borrower: SPTL.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

98 positions became 100: 2 added (1.7% of the fund at the later date), 0 dropped (0.0% at the earlier date). Half the sum of all weight changes, a turnover proxy: 3.8%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of SPTL compared this way, as a feed: changes.xml · all funds: filings received.
