This section applies where the market value of employment-related securities which are convertible securities or an interest in convertible securities (determined as if they were not) has been reduced by at least 10% as a result of things done otherwise than for genuine commercial purposes within the period of 7 years ending with the acquisition.

The reference to the market value of the employment-related securities in the definition of NCMV in section 442(5) (value of convertible securities at time of acquisition) is to what would be the market value but for the reduction as a result of the things done as mentioned in subsection (1) (and but for the fact that they are convertible securities or an interest in convertible securities).
