Pretty much.
There are a couple differences though.
.....
HPCT applies to open end transactions where HPMLs are only for closed.
.....
Actually, section 1026.43, which defines covered transactions (including HPCTs) doesn't apply to open-end transactions. In 1026.43(a) it says that HELOCs covered by section 1026.40 are excluded. In the TILA ATR language, all open-end transactions are excluded. The Bureau has agreed, albeit unofficially so far, that the exclusion extends to all open-end credit transactions.
