Congressional Findings and Declaration of Purposes
Section 2605(a) of div. A of Pub. L. 104–208 provided that:
“(1)Findings.—The Congress finds that—
the informed use of leasing results from an awareness of the cost of leasing by consumers; and
there has been a continued trend toward leasing automobiles and other durable goods for consumer use as an alternative to installment credit sales and that leasing product advances have occurred such that lessors have been unable to provide consistent industry-wide disclosures to fully account for the competitive progress that has occurred.
“(2)Purposes.—The purposes of this section are—
to provide for adequate cost disclosures that reflect the marketplace without impairing competition and the development of new leasing products; and
“(C) to provide the Board with the regulatory authority to assure a simplified, meaningful definition and disclosure of the terms of certain leases of personal property for personal, family, or household purposes so as to—
enable comparison of lease terms with credit terms, as appropriate; and
assure meaningful and accurate disclosures of lease terms in advertisements.”
 So in original. Probably should be “this”.
