Will this force a reinitialize in Merge Replication Topology?

I need to add a couple of columns to a table that is a part of a replication set. It is not a constraint column or a part of any article filters and it allows NULL. I have a pretty good idea that I can run this:

ALTER TABLE tblPlanDomain 
    ADD ReportWageES VARCHAR (100) NULL

and NOT force all my clients to reinitialize but I was hoping for some reassurance. Can anyone verify this one way or the other for me?

Thanks,

It would seem, based on that, that the answer to my question is NO but I would still like a human confirmation.
