So if I look back during the select committee period, we had submissions from a number of submitters. In particular, I can recall the Browns Bay Chinese Society submission, and they had set out a table which is very similar to the one that is in the revision-tracked (RT) version of the bill that was reported back by the select committee. In that particular table—although it was slightly different in the RT version—I understand that we had come to an agreement during the select committee period that we would go by periods of dates so that there wasn't so much of a cliff so that as soon as somebody had got to the point where they were able to receive superannuation, instead of just dropping off the cliff straight away from a 20-year to a 10-year applicant period, we would phase it in over particular periods. So if I looked at the RT version of the bill, I think it was clause 4, replacement section 8(4), it was around, I think, between 1 July 1957 and 30 June 1959 it was 11 years; if you look at 1959 and 1961, it was 12; 1961 and 1963, 13; and it carries right through to on or after 1 July 1975, which was 20 years.
