Representation of BAC Florida Bank in sales of portfolios of $400 million of mortgage loans originated by BAC and sold on a servicing-retained basis. These transactions created profits from both the portfolio sales and the retention of the servicing rights, in turn enabling BAC to make additional loans. The initial transaction of $120 million was the largest portfolio sale in BAC's history. The buyer, U.S. Mortgage Finance, utilized a conduit credit facility offered through West LB AG to purchase the portfolio. The transaction presented the unique challenge of balancing the needs of BAC, as a third party unaffiliated seller, with the securitization and loan requirements West LB AG sought to impose on its borrower, U.S. Mortgage Finance.
