I did my best to update my overview of warants and options based on the information given in the 20-F and the Financial Statements:

Unfortunately we won't find all the information we'd like to know in the underlying documents. For example, since Geoffrey Taylor is no longer a director, his options are no longer included in the respective list in the 20-F. Consequently, in my list those numbers are as of 2014-12-31 only, not 2015-12-31.
Aside from such uncertainties, I hope you still consider the list useful. At least the orders of magnitude should be correct. :-)
If you discover any faults or possible improvements, please let me know!
