Special pro rata pensions were introduced in 1988 for certain persons who failed to qualify for contributory pension, because they were out of insurance for periods prior to 1974 when their earnings exceeded the insurable limit, and their yearly average of contributions was less than 20. These arrangements were devised to deal with the once off situation arising from the removal of the remuneration limit in 1974. Under the 1988 arrangements, pensions are awarded for averages of between five and 19 contributions. As at December 1996, 424 people were in receipt of these special pro rata pensions.
If an insured contributor's income went over the insurable limit, the old insurance card had an instruction — under the heading "Instructions to Insured Persons"— in bold black print to the effect:
"6. if you cease to be insurably employed and wish to continue your insurance as a voluntary contributor notify the Department immediately."
