XYZ US and XYZ UK are commonly controlled business organizations.
XYZ US maintains a 401(k) plan. XYZ UK is not a participating employer under that plan.
Martha ends her employment with XYZ US on June 30, and becomes XYZ UK’s employee on July 1.
If employment by a business organization commonly controlled with the 401(k) plan’s sponsor otherwise would mean a change is not a severance-from-employment, is there anything that varies such a rule if the next employing organization is outside the USA?
