Union, Nonunion - 1 wrap plan?

[TPApril]

Company has some benefit plans for Union ee's only, some plans for Non-Union only and some plans include both. Currently there are two wrapped plans (union, nonunion) but the nonunion plan has some benefits which include union. what might a best approach be - keep the two plans separate or actually just combine all into one megawrap plan?

okay, another question: company has two locations, each in a different state with a different set of benefits. They decide to create a wrapped plan for both groups. Can they provide different SPD's or must there be 1 SPD that includes all benefits within the wrapped plan?
