Primus Guaranty Comments on CDS on Asset-Backed Securities

Primus Guaranty, Ltd. (NYSE:PRS) today announced that two asset-backed securities, referenced by credit default swaps ("CDS”) written by Primus Financial Products, LLC ("Primus Financial”), were downgraded below Caa2 by Moody’s Investors Service ("Moody’s”). The notional principal on these CDS with counterparties is $15 million. Under the terms of the ISDA master agreement governing CDS on asset-backed securities, a downgrade of the underlying security to CCC (Standard & Poor’s) or Caa2 (Moody’s), or below, is considered a credit event.

Primus Financial will make a provision for the credit event in the first quarter. In accordance with the ISDA master agreement, until the referenced asset-backed security is presented to the company, the credit swaps remain outstanding and premiums are required to be paid by the counterparty. Primus Financial does not expect any immediate capital impact. As of March 31, 2009, Primus Financial’s portfolio of CDS on ABS that have not technically defaulted was $5 million.
