FA-61802 / Options payoff and settlement / Member archive
Exercise notice acceptance cutoff: the time cutoff is applied to the day before expiry · case 02
Early exercise notices filed the evening before expiry are rejected.
Case contract
Inputs expiry date, submission [y,m,d,hh,mm], cutoff [hh,mm], extension minutes and member flag. Notices after the expiry date are "expired"; notices on earlier dates are "accepted"; on the expiry date a notice is accepted if its minute of day <= cutoff (+extension for members), else "late".
Why this case matters
Option expiry, exercise and settlement engines move cash and shares; a wrong branch misstates obligations.
One recorded failure
