      Example: calculation of amount of tender from the ROC tender offer and transaction cost:
      (a) If shareholder A tenders 1, 000 shares (shares already deposited) for a consideration of NT$45 per share, the total purchase amount is NT$45, 000.
      
      Transaction cost: (1) securities transaction tax is NT$135 (45, 000 x 0.3% = NT$135), (2) handling charge of TDCC is NT$20, (3) handling charge of his or her securities broker is NT$20, (4) remittance fee is NT$10, for a total of NT$185.
      
      Net amount of tender received by shareholder A = NT$45, 000 – NT$185 = NT$44, 815
      
      (b) If shareholder B tenders 10, 000 shares (shares already deposited) for a consideration of NT$45 per share, the total purchase amount is NT$450, 000.
      
      Transaction cost: (1) securities transaction tax is NT$1, 350 (450, 000 x 0.3% = NT$1, 350), (2) handling charge of TDCC is NT$20, (3) handling charge of his or her securities broker is NT$20, (4) remittance fee is NT$10, for a total of NT$1, 400.
      
      Net amount of tender received by shareholder B = NT$450, 000 – NT$1, 400 = NT$448, 600
      
      
   2. After shareholders of SPIL participate in the tender, will ASE definitely purchase the shares tendered?
      
      If the total number of common shares participating in the ROC tender offer reaches the minimum threshold of 155, 818, 056 shares (approximately 5% of the total issued and outstanding shares of SPIL) before 3:30 p.m. on September 22, 2015, the amount condition of this tender offer will be satisfied.
