Each of the major mutual fund firms--Vanguard, Fidelity, Schwab, etc. have materials on these that are fairly comprehensive and understandable as well. Hope that helps !

My answer if the Employer has inadvertently done this is to follow the correction procedures for DFVCP which we have done for employers many times. That is, assuming it was an honest mistake. If it is not an honest mistake, agree with much of what has been said, the employee has perhaps bigger problems than this single issue. But DOL has gone after bad actors in this type of space many times successfully, and will continue to do so.
