- F1Each American Depositary Share represents five (5) Common Shares.
- F2Common Shares purchased by the administrator of the issuer's Employee Stock Purchase Plan ("ESPP") on behalf of the filer pursuant to terms predetermined by the issuer.
- F3The price was translated from the average purchase price of NT$2,404.3453 in New Taiwan dollars, at the rate of NT$31.552 to US$1.

- F6The Equity Linked Notes are issued by UBS AG that reference a basket of equity securities that includes the issuer's American Depositary Shares. The principal amount of the notes is US$150,000. The notes are exercisable and expire on March 4, 2027 (the "Exercisable Date"). Under the terms of the notes, if the notes are not redeemed early and the closing price of the worst-performing basket component is below its strike price on the Exercisable Date, the notes may be settled by delivery of shares or American Depositary Shares of that worst-performing basket component plus cash in lieu of any fractional share. The strike price for each basket component equals 55% of its initial reference level. If the issuer's American Depositary Shares are determined to be the worst-performing basket component, settlement may result in delivery of up to 703 American Depositary Shares of the issuer at a strike price of 213.2515 per American Depositary Share. [Continued in footnote 7]
- F7[Continued from footnote 6] In addition, the notes may be redeemed for cash, (i) if, during the observation period prior to the Exercisable Date, the closing price of each basket component has reached its initial reference level at least once, or (ii) if the notes are not redeemed early and the closing price of the worst-performing basket component is at or above its strike price on the Exercisable Date.
