Custom Benefit Plan?

[Guest 10graham43]

Recently received some unsolicited information on a "Custom Benefit Plan" that would allow a small business owner to contribute a "minimum of $70,000 to the owner's personal account, without similar increases for the rank and file employees."

Does anyone have any thoughts as to what this might be?

I have a general knowledge of retirement plans, but am not sure if this might be a fit here. Four member LLC with no other employees. Members ages range from 52-61 and K-1's will show income of 150,000+ each.

Thanks.
