Definition - What does Portability mean?
Portability refers to the insured's right to continue their insurance coverage even after they have lost their their job, transferred to another employer, or suffered a health condition that rendered them incapable of working.
Insuranceopedia explains Portability
Portability is an important feature of group insurance benefits. Group policies are usually work-related or initiated by an employer. Without portability, the insured can lose their coverage if they lose their employment. Portability eliminates this vulnerability by allowing them to keep their coverage so long as they continue to make the premium payments. Converting a group life insurance policy to an individual one, however, can be costly.
