The Office of the Comptroller of the Currency (OCC) is issuing, as an appendix to part 30 of its regulations, guidelines concerning the residential mortgage lending practices of national banks and their operating subsidiaries (Guidelines) as a further step to protect against national bank involvement in predatory, abusive, unfair, or deceptive residential mortgage lending practices. The Guidelines describe particular practices inconsistent with sound residential mortgage lending practices. They also describe other terms and practices that may be conducive to predatory, abusive, unfair, or deceptive lending practices, depending on the circumstances, and which, accordingly, warrant a heightened degree of care by lenders. In addition, the Guidelines address the steps that banks should take to mitigate risks associated with their purchase of residential mortgage loans and use of mortgage brokers to originate loans. The Guidelines focus on the substance of activities and practices, not on the creation of policies. The standards contained in the Guidelines are enforceable pursuant to section 39 of the Federal Deposit Insurance Act and the implementing process set forth in part 30 of the OCC's regulations.
