J.P. Morgan Chase & Co. next year plans to issue the first U.S. commercial mortgage-backed securities supported by defaulted loans since the 1990s as it revives a practice that regulators used to extricate the nation from the savings-and-loan crisis. The investment bank has approached rating agencies with two pools of distressed loans that it acquired from European banks and other financial institutions, according to people familiar with the matter. J.P. Morgan wants to create commercial mortgage backed securities, or CMBS, backed by the troubled properties with interest and principal payments coming from property sales and the buildings' reduced cash flows.
