a person who has rights under the occupational scheme but is neither a pensioner under it nor a person to whom rights are accruing under it by virtue of his employment
A person entitled to a pension payment at a future date. Normally this would be an early leaver but the term can also be used to describe someone whose retirement has been postponed.
When someone stops being an active member of a pension scheme, the pension benefits they have earned become preserved benefits , and the member is now called a deferred pensioner. They will get these benefits at a later date.
