Looking for advice on how best to handle: For several loans, at origination, for a closed-end ARM, we disclosed an index that doesn't exist. We erred in referring to the 1 year Treasury Constant Maturity Index as the "1 Year Weekly US Treasury Bill." Rates are not due to change for several years (in 2020), but how best to handle? Is there any model language out there? I see under 1026.40 that if an original index is no longer available, its ok to substitute a similar index, but that seems to refer only to open-end credit. I appreciate your advice. Thank you.
