On September 24th, the Federal Reserve Board published in the Federal Register interim rules that were originally announced on August 16th, 2010. The interim rules revise the disclosure requirements for closed-end mortgage loans under Regulation Z (Truth in Lending). The interim rule implements provisions of the Mortgage Disclosure Improvement Act that require lenders to disclose how borrowers' regular mortgage payments can change over time. The interim rule is effective October 25th, 2010. Compliance is optional until January 30th, 2011. The rule's requirements are mandatory for transactions for which an application for credit is received by the creditor on or after that date. Comments should be submitted on or before November 23rd, 2010. See also Federal Reserve Board Press Release.
