In October 2006, NCUA issued additional guidance to its Federally Insured Credit
Unions in regards to: (1) managing risks associated with open-end HELOCs that
contain interest-only features; and (2) addressing risks associated with the growing use
of non-traditional mortgage products—including interest-only and payment option
adjustable-rate mortgages--that allow borrowers to defer payment of principal and,
sometimes, interest.
