Sellers of bonds backed by mortgages and auto loans would have to give investors details including the borrowers' income and credit scores under rules the U.S. Securities and Exchange Commission (SEC) is poised to consider this week, according to two people briefed on the plan.

The SEC will vote Aug. 27 on the final rules, which were mandated by the Dodd-Frank Act after investors were burned by soured debt sold by Wall Street before the 2008 credit crisis. The biggest sellers of asset-backed securities include Bank of America Corp., JPMorgan Chase & Co., Deutsche Bank AG, Citigroup Inc., and Goldman Sachs Group Inc.

Securities backed by loans for houses, autos, and commercial real estate would fall under the rules, which require more extensive disclosure to bond buyers than the SEC's initial 2010 plan, said the people, speaking on condition of anonymity because the details aren't public. The agency's move comes amid a surge in subprime auto loans that are being fed into securities, a business being probed by U.S. prosecutors.
