The Structured Finance Industry Group has 55 member institutions, with roughly 30 more firms considering joining, according to Reggie Imamura, a PNC executive and the trade group's chairman.

SFIG was formed after prominent members of the American Securitization Forum, such as Bank of America Merrill Lynch (BAC), Citigroup (C) and Morgan Stanley (MS), defected the trade group.

Babson Capital Management has joined SFIG, which was started mainly by underwriters, issuers and firms they hire.
