ETASSUM41140 | Schedule 4 Company Share Option Plan (CSOP): General requirements: Unacceptable features
From HM Revenue & Customs · Employee Tax Advantaged Share Scheme User Manual
Unacceptable features of Schedule 4 Company Share Option Plans include, but are not limited to:
payment for shares by instalments or payment in advance;
payment of option price in shares (the provision is often included in US plans where it may secure a tax advantage);
exercise of options in return for cash rather than shares (stock appreciation rights);
exercise of options resulting in payment to the employee of only the rise in value of shares over the option period, in cash or shares;
the grant of an option being made conditional on the participants entering into “put” options (by which they could be compelled to acquire shares at the specified, possibly disadvantageous, price);
the grant or exercise of options being made conditional on employees giving up rights to participate in other approved schemes; or
certain loan arrangements.
Part 2 of Schedule 4 ITEPA also sets out the monetary limits on the provision of share options determined in relation to the market value of the shares to be acquired.
