Supplemental Retirement Account?

[Dennis Povloski]

I've come across a small dentist office where the dentist and his wife make salary deferrals into something called a "Supplemental Retirement Account" with Merrill Lynch. I've never heard of this, so I Google'ed it. Everything that popped up referred to either a 403(b) or a 457 plan for a college or university. Neither of which would be appropriate for this particular client.

Does anyone know anything about these SRAs?

Thanks!
