Credit metrics show mixed performance
Among the K-LOCs, three loan groups representing 7.2% of the pool carry estimated losses. KBRA says the K-LOC population totals $149,664, with estimated losses of $23,530 tied to the identified troubled exposures.Excluding K-LOCs with estimated losses, the transaction's weighted-average KLTV is 91.9%, improving from 96.9% at the last review and 97.6% at securitization.
