If the security underlying a share option ceases to be officially listed on Amsterdam Exchanges, the financial position of the option investor is safeguarded as far as possible. The number of ways in which option listing may continue has been extended, e.g. by the new "trading" segment. But even if option listing cannot continue, the financial position is in principle safeguarded by use of a fair value method specified in the rules. This method determines a price which aims to be as close as possible to the market price before the announcement of the corporate event which ultimately caused the option to cease being listed.
This policy also eliminates a major uncertainty from the pricing of share options, because it is no longer necessary to estimate the probability of successfully maintaining an option listing on Amsterdam Exchanges in the case of a takeover, for example. The rule takes effect today and also applies to all outstanding option positions.
Finally: consequences for warrants to be listed: Amsterdam Exchanges will advise issuers of listed warrants that they are expected to use the same fair value method for newly listed warrants or, if they prefer to deviate from this and use a different system, include an extensive section on this matter in their prospectus.
