In addition, Fitch has assigned Derivative Counterparty Ratings (DCR) of 'A+(dcr)' to JPM and Bear Stearns Companies, LLC and a DCR of 'AA-(dcr)' to JPMorgan Chase Bank N.A as part of its roll-out of DCRs to significant derivative counterparties in Western Europe and the U.S. DCRs are issuer ratings and express Fitch's view of banks' relative vulnerability to default under derivative contracts with third-party, non-government counterparties.
