The final rule implements and modifies several mortgage servicing rules under the Truth in Lending Act (TILA). The rule requires servicers to provide certain notices for adjustable-rate mortgages, periodic statements for residential mortgage loans and prompt crediting of mortgage payments and responses to requests for payoff amounts. The rule also amends current TILA provisions related to the scope, timing, content and format of disclosures to consumers regarding interest rate adjustments to variable-rate transactions. The proposed rule was published on September 17, 2012 (77 FR 57200). On May 2, 2013 (78 FR 25638), the CFPB proposed amendments to the final rule.
