1) Does the new rule that allows a participant to diversify employer stock only apply to publicly traded stock?

2) Does this apply to an ESOP with only employer contributions?

3) Do the same rules apply to a 401k with employer stock?

4) Does anyone have a link to the final regulation as it relates to this issue?

Thank you very much for any help.
