Since Nasdaq Index warrants are also warrants, they have expiry dates. Settlement will be made after the expiry date.
The settlement reference value of a Nasdaq Index warrant is the settlement price of the futures contract on the expiry date of that month. To give you an example, a Nasdaq Index warrant with an expiry of 19 March 2021, its settlement price will use the settlement price of a Nasdaq-100 futures expiring on 19 March 2021 (US time).
Like other warrants, an in-the-money warrant will have cash value after the expiry date, the value of an out-of-the-money warrant is 0 after the expiry date. The settlement formulas of warrants are as below:
For example, the exercise price of a particular Nasdaq Index warrant is 12,500, the entitlement ratio is 25,000:1, and the expiry date is 19 March. On the expiry date, the settlement price of Nasdaq-100 futures is 13,000, the USD/HKD exchange rate is 7.75.
Cash value after settlement = ( 13,000 – 12,500 ) ÷ 25,000 x 7.75 = $0.155
