An on-market buyback is paying the market price for PXUPA. The company would just employ a broker to buy back say, 10% of all hybrids. At $8.40 per hybrid, it has a market cap of $23,940,000 for the class of 2,850,000 total on issue. It would cost the company about $2.4m. This is why Paperlinx has said the cost of a partial buyback would not be material.
