You have some shares that were from the demutualisation of an insurance company. I have compiled a list of shares that I frequently get asked what the original cost of the share was. Below is a list of those shares:-
|Colonial Mutual (now CBA)||19/5/97||$3.31|
Bear in mind that some of these companies have now have been taken over, and you will now own shares in the new company.
The cost base remains the same, if you owned 1000 shares in Colonial Mutual, the cost base of $3310 will apply the the sale price of your Commonwealth Bank Shares (CBA).
