Some employees of Company A were participants in Plan B which offered a lower rate of return, lower deferral limit & lower employee base to the participants than Plan A.

These Employees are now being transferred to Plan A.

We need to find how these employees could have incurred the losses, the nature of these losses & to calculate and make whole the economic losses suffered by the Employees and the Plan.

We also have to analyze how the IRS or DOL would recommend these losses to be compensated.

Could Anyone please help in correcting the above operational defects ?

Were they supposed to be in Plan A all along? Why? (Plan document? Plan B only covers employees of Company B?)

Apparently so. But this fact was realized only recently. Plan B is being maintained by a State and is applicable to only employees coming under that particular state. The effected employees are still continuing to be employed in the state but are actually employees on the roll of Company A.
