The target portfolio par amount is €400 million with exposures to 152 obligors. The obligors in the portfolio have a K-WARF of 2146, which represents a weighted average portfolio assessment of approximately B.

Diameter currently manages more than $5.0 billion in assets across ten U.S. CLOs, and this transaction represents its inaugural European CLO issuance.
