Employee Communication - source for clarification of legislative requirements

[Guest keep it simple]

Does anyone know of a source for obtaining information relating to employee benefit communication legislative requirements?....in plain English? I am not an attorney and would appreciate an easy-to-decipher source for figuring out what information needs to be disclosed to employees and when. All recommendations would be appreciated.

For the source and explanation of what was required to be in the SPD content as of the last major set of requirements, go to www.inplainenglish.com and look in the table of contents under SPD.
