Countrywide Securities Corp. recently settled with Massachusetts to the tune of $17.3 million, the latest development in an on-going investigation into residential mortgage securitization practices in Massachusetts.

The settlement includes an $11.3 million payment to the state pension fund and an additional $6 million paid to the commonwealth. Countrywide’s payout is the latest of six such settlements totaling more than $300 million since 2009.

"We are pleased to return these critical public funds to the state pension system," Attorney General Martha Coakley said in a statement. "It is important to hold Wall Street accountable for its role in the subprime lending crisis. Our office will continue its leading role in this area as we work to help homeowners and others harmed by investment banks."

Assistant Attorneys General Aaron Lamb, Peter Leight, and Glenn Kaplan of the state’s Insurance and Financial Services Division handled the investigation into Countrywide’s securitization practices.
