Hey,

Reading the quarterly I noticed something interesting in the listed options pane.


On the appendix 3b March 2010 30 million options were issued with an expiry of 31/05/2012.

Then I look at the quarterly dated 30th of April says that the 30m options were issued with expiry 17th march 2013.


The only option code I know of is "QMNO" so are my options expiring in 2013 or 2012? I would've thought that these would need a separate code if they have a different expiry date?
