“Series” of memberships means memberships within a class of memberships that have the same rights, privileges, preferences, restrictions, and conditions, but that differ in one or more rights, privileges, preferences, restrictions, or conditions from other memberships within the class. Certificated securities and uncertificated securities do not constitute a different series if the only difference is certificated and uncertificated status.
