Context

• This was an option grant, not an immediate purchase of stock; Bruce must exercise the options (and meet any tax/holding conditions) to acquire ordinary shares. The initial 50% vesting means some options are immediately exercisable subject to the exercise price and any company restrictions, while the remainder vests over the next four years contingent on continued service. The filing does not indicate any immediate sale of shares.
