---

1. Market capitalization. For purposes of Section 3(a)(55)(C)(i)(III)(bb) of the Act:
   
   
   1. On a particular day, a security shall be 1 of 750 securities with the largest market capitalization as of the preceding 6 full calendar months when it is included on a list of such securities designated by the Commission and the CFTC as applicable for that day.
      
      
   2. In the event that the Commission and the CFTC have not designated a list under paragraph (a)(1) of this section:
      
      
      1. The method to be used to determine market capitalization of a security as of the preceding 6 full calendar months is to sum the values of the market capitalization of such security for each U.S. trading day of the preceding 6 full calendar months, and to divide this sum by the total number of such trading days.
         
         
      2. The 750 securities with the largest market capitalization shall be identified from the universe of all NMS securities, as defined in Rule 242.600 of this chapter that are common stock or depositary shares.
         
         
2. Dollar value of ADTV.
   
   
   1. For purposes of Section 3(a)(55)(B) of the Act:
      
      
      1. 
         
         1. The method to be used to determine the dollar value of ADTV of a security is to sum the dollar value of ADTV of all reported transactions in such security in each jurisdiction as calculated pursuant to paragraphs (b)(1)(ii) and (iii).
            
            
         2. The dollar value of ADTV of a security shall include the value of all reported transactions for such security and for any depositary share that represents such security.
            
            
         3. The dollar value of ADTV of a depositary share shall include the value of all reported transactions for such depositary share and for the security that is represented by such depositary share.
            
            
      2. For trading in a security in the United States, the method to be used to determine the dollar value of ADTV as of the preceding 6 full calendar months is to sum the value of all reported transactions in such security for each U.S. trading day during the preceding 6 full calendar months, and to divide this sum by the total number of such trading days.
         
         
      3. 
         
         1. For trading in a security in a jurisdiction other than the United States, the method to be used to determine the dollar value of ADTV as of the preceding 6 full calendar months is to sum the value in U.S. dollars of all reported transactions in such security in such jurisdiction for each trading day during the preceding 6 full calendar months, and to divide this sum by the total number of trading days in such jurisdiction during the preceding 6 full calendar months.
            
            
         2. If the value of reported transactions used in calculating the ADTV of securities under paragraph (b)(1)(iii)(A) is reported in a currency other than U.S. dollars, the total value of each day's transactions in such currency shall be converted into U.S. dollars on the basis of a spot rate of exchange for that day obtained from at least one independent entity that provides or disseminates foreign exchange quotations in the ordinary course of its business.
            
            
      4. The dollar value of ADTV of the lowest weighted 25% of an index is the sum of the dollar value of ADTV of each of the component securities comprising the lowest weighted 25% of such index.
         
         
   2. For purposes of Section 3(a)(55)(C)(i)(III)(cc) of the Act:
      
      
      1. On a particular day, a security shall be 1 of 675 securities with the largest dollar value of ADTV as of the preceding 6 full calendar months when it is included on a list of such securities designated by the Commission and the CFTC as applicable for that day.
         
         
      2. In the event that the Commission and the CFTC have not designated a list under paragraph (b)(2) of this section:
         
         
         1. The method to be used to determine the dollar value of ADTV of a security as of the preceding 6 full calendar months is to sum the value of all reported transactions in such security in the United States for each U.S. trading day during the preceding 6 full calendar months, and to divide this sum by the total number of such trading days.
            
            
         2. The 675 securities with the largest dollar value of ADTV shall be identified from the universe of all NMS securities as defined in Rule 242.600 of this chapter that are common stock or depositary shares.
            
            
3. Depositary Shares and Section 12 Registration. For purposes of Section 3(a)(55)(C) of the Act, the requirement that each component security of an index be registered pursuant to Section 12 of the Act shall be satisfied with respect to any security that is a depositary share if the deposited securities underlying the depositary share are registered pursuant to Section 12 of the Act and the depositary share is registered under the Securities Act of 1933 on Form F-6.

      2. If no reported transactions in a security have taken place in the United States, the closing price of such security shall be the closing price of any depositary share representing such security divided by the number of shares represented by such depositary share.
         
         
      3. If no reported transactions in a security or in a depositary share representing such security have taken place in the United States, the closing price of such security shall be the price at which the last transaction in such security took place in the regular trading session of the principal market for the security. If such price is reported in a currency other than U.S. dollars, such price shall be converted into U.S. dollars on the basis of a spot rate of exchange relevant for the time of the transaction obtained from at least one independent entity that provides or disseminates foreign exchange quotations in the ordinary course of its business.
