I think I am aligned with FGC in not being convinced that a loan at 12%, even within the past 5 years, is not a PT. I also am not convinced that it is a 401(a)(4) problem just because HCEs might be able to "afford" a super-high rate while NHCEs can't afford it. However, I do believe it is susceptible to being re-characterized as a vehicle for making non-deductible contributions which, presumably, aren't allowed by the plan document and would probably result in an ACP failure.
