Sir, I want to thank Ms Sylvia Lim for her clarifications. I also want to commend her for knowing the mathematics very well. Sir, if you want to take a step back on the LUP programme, this is a programme that was added on in year 2001, to give access to all the residents in different floors. We know back in the older days when HDB flats were first built, there were lift landings, and residents actually shied away from those units because it meant noise and loss of privacy, and so on. So actually, people wanted to stay away from lift landings. Anyway, fast forward, decades later, we find that people are requiring that facility, especially when they are getting older, and there is no question about the need. So, the LUP programme comes in and, as I have mentioned, this is a $5.5 billion programme over a period of 15 years or so. As you can imagine, when this programme was introduced, the estates are at different ages. Some were maybe 15 years old; some may be 20 years old; and some may be very near the lift replacement cycle which is 28 years. As part of the discipline of the Town Councils, and I mean all Town Councils, they always set aside a portion of their S&CC charges into a sinking fund. And one of the biggest items of the sinking fund usage is actually for lift replacement. So, at the 28th year, if you have been saving regularly, conscientiously, you would be able to have, say, $100,000 to replace each of the lifts that is "retiring".
