tax law on option conversion, page-8

Agent 86, are you sure about the disposal of KIKO options being treated the same for cap gains purposes as sale of shares are. That is not what I have read it to be from the Personal Investors Guide to Capital Gains Tax from the ATO. If you are referring to options being issued directly to you from a company, for no cost, then the date you are considered to have received these options [kiko] is when you bought the original shares, as it states below:-
CHAPTER B3
Additional information for shares and units
This chapter briefly explains less common situations for
personal investors, including:
�¡ rights or options
�¡.
Rights or options to acquire shares or units
If you hold shares or units, you may be issued rights
or options to acquire additional shares or units at a
specified price.
Rights and options issued directly to you from
a company or trust for no cost
You are taken to have acquired the rights and options at
the same time you acquired the original shares or units.
If you acquired the original shares or units on or after
20 September 1985, you make a capital gain if the capital
proceeds on the sale or expiry of the rights or options are
more than their cost base. You make a capital loss if the
reduced cost base of the rights or options is more than
those capital proceeds.
Rights and options you paid to acquire
from a company or trust or you acquired from
another person
If you acquired your rights or options on or after
20 September 1985, they are treated much like any
other CGT asset and are subject to CGT.
There are special rules that apply if you exercise the
rights. For more information, or if you acquire rights or
options under an employee share scheme, see the Guide etc.
