Ann: Notice of Annual General Meeting/Proxy Form, page-27

Hey mate, NVA appointed PAC Partners to conduct the buy back on their behalf as per ann on 12th Oct, so PAC Partners would be like any other buyer who submits the orders on the market just like you and me, so these would show up on the ASX course of sales when they get filled so by looking at the size of the orders we could possibly make an educated guess that they could be the buy back orders. I have been comparing the Appendix E’s with the ASX course of sales and they do tally up so they do appear on the ASX course of sales. Obviously sometimes the order could get part filled from Chi-x too but you can’t see these on ASX course of sales so I use another website to view Chi-x trades
If you are interested in looking up Chi-x trades then I recommend you use this site which I find useful https://stocknessmonster.com/quotes/nva.chia/
