What this supply is, and what converts it
  • Price-triggered253.5M · 14.7% of shares
    Options and warrants — they convert when the share price clears their exercise price.
  • Condition-triggered212k · 0.0% of shares
    Performance and incentive rights — they convert when a hurdle is met, not at a price, and can lapse to nothing.

Exercise price on record: 246.0M priced, 7.5M at a stated nil price, 212k where the filing never states one. A security with no exercise price is never counted in the money — nothing is paid to convert it, so there is no price for it to be above.

Each figure is the filing’s own count of securities, not a share count — a 2A never states what one security converts into.

At $0.047 today, 0 securities are in the money (0.0% of shares on issue). No more priced supply until 1.5× today’s price, which takes it to 65.5M (3.8% of shares).

  • Priced supply in the money at the price on the axis — the curve, and the only thing on it. Ten prices, sampled: between two of them the true figure lies between the two.
  • 7.5M (3.0% of the supply above) states a nil exercise price — nothing is paid to convert it, so no share price switches it on or off. It is the flat band, and it is not part of the in-the-money figure.
  • 212k (0.1% of the supply above) states no exercise price at all. It cannot be called in or out of the money at any price, which is why it is hatched rather than plotted.

BSXALRightsCondition-triggered212kFiling Meeting

“Nil” is a stated nil exercise price: nothing is paid to convert. An em dash means the filing names no exercise price at all. Security is read from the filing’s own class description; an em dash there means the description is not one this table labels. One row is one security class, at the number stated in the most recent quotation application that restated it — linked, and dated, in the last column.

A condition-triggered class has no exercise price and usually no expiry: what it vests on is set by a shareholder resolution, not by the register. Where the company lodged a notice of meeting before the class first appears here, it is linked as “Meeting” — that is where terms of this kind are put to shareholders. It is not confirmation that the document sets this class’s conditions, and no link appears where there is no such filing.

3 classes ceased in the last 12 months and are not counted above
The company’s own Appendix 2A restates each of these at zero. They are excluded from the overhang, the in-the-money supply and every figure on this page. Each count is the filing’s own count of securities in the class, not a share count — a 2A never states what one security converts into.
