The regulation is divided into subparts. Subpart B relates to open-end credit lines (
revolving credit accounts), which includes credit card accounts and home-equity lines of credit (HELOCs). Prior to revisions finalized in 2001, the language provision referenced Spanish language disclosures in Puerto Rico; the rule now permits disclosures in any language if English versions are available on request, except for advertisements. Subpart E contains special rules for mortgage transactions. • § 1026.35 establishes requirements for "higher-priced" mortgage loans (HPMLs). • § 1026.40 sets the requirements for home equity plans. Several appendices contain information such as the procedures for determinations about state laws, state exemptions and issuance of staff interpretations, special rules for certain kinds of credit plans, a list of enforcement agencies, model disclosures that, if used properly, will ensure compliance with the Act, and the rules for computing
annual percentage rates in closed-end credit transactions and total annual loan cost rates for
reverse mortgage transactions. ==Right of rescission==
