May only apply if you paid into the scheme before 1 October 2006. The rule is satisfied if your age at the date you draw your benefits and your membership add up to 85 years or more (part years are ignored). If you are part-time, your membership counts at its full calendar length. If you have deferred benefits the rule is satisfied if your age at the time you take your benefits and the membership you would have had if you had remained in the scheme, add up to 85 or more.
