(1)The following events relating to the employee are disqualifying events in relation to a qualifying option—
(a)when the employee ceases to be an eligible employee in relation to the relevant company as a result of ceasing to meet the requirement in paragraph 25 of Schedule 5 (the employment requirement);
(b)when the employee ceases to be such an employee as a result of ceasing to meet the requirement in paragraph 26 of that Schedule (the requirement as to commitment of working time).

(4)The “statutory threshold” means—
(a)25 hours, or
(b)if less, 75% of the employee’s working time.
