BorrowerOn loanShare of the loan
GOLDMAN SACHS & CO. $196,020 100.0%

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.

Since the previous filing

2026-01-31 → 2026-04-30

41 positions became 42: 1 added (2.7% 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: 5.6%.

Every filing of IBTI compared this way, as a feed: changes.xml · all funds: filings received.
