AMENDMENT NO. 6 TO SCHEDULE 13D

Reference is hereby made to the statement on Schedule 13D filed with the Securities and Exchange Commission by the Reporting Persons with respect to the Common Shares on April 8, 2019, Amendment No. 1 thereto filed on June 4, 2019, Amendment No. 2 thereto filed on November 13, 2019, Amendment No. 3 thereto filed on December 6, 2019, Amendment No. 4 thereto filed on December 9, 2019 and Amendment No. 5 thereto filed on December 10, 2019   (as so amended, the “Schedule 13D”).  Terms defined in the Schedule 13D are used herein as so defined.

The following items of the Schedule 13D are hereby amended as follows:

Item 4.	Purpose of Transaction
Item 4 of the Schedule 13D is hereby amended and supplemented to include the following: Iljin SNT and Iljin Steel have filed an updated Form 144 with the Securities and Exchange Commission disclosing their intention to sell Common Shares in broker transactions over the 90 day period following the initial filing of the Form 144 by Iljin SNT.  Notwithstanding such bona fide intention to sell, decisions to sell will be made depending on market conditions, and so there can be no assurance that Iljin SNT and/or Iljin Steel will sell all of such Common Shares within that time period. Further, Iljin SNT and Iljin Steel may file additional Forms 144 from time to time with respect to the sale of such Common Shares if they are not completed within the time period covered by a previously filed Form 144, or in the event that the volume restriction allows for additional Common Shares to be sold.
Item 5.	Interest in Securities of the Issuer
Paragraphs (a), (b) and (c) of Item 5 of the Schedule 13D are hereby amended and restated to read as follows: (a)-(b) The information requested by these paragraphs is incorporated herein by reference to the cover pages to this Amendment No. 6 to Schedule 13D. (c)  On December 11, 2019 Iljin SNT sold 200,000 Common Shares in open market broker transactions pursuant to Rule 144 at a weighted average price of $18.13 per share. Such shares were sold in multiple transactions at prices ranging from $18.03 to $18.21.  Iljin SNT undertakes to provide to the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within each such range. In addition, the information disclosed below pursuant to Item 6 is incorporated into this paragraph (c) by reference.
Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
Item 6 of the Schedule 13D is hereby amended and supplemented to include the following: On December 18, 2019, NH and Mr. Huh entered into an agreement with respect to the Put Option pursuant to which Mr. Huh agreed to purchase 3,410,892 Common Shares, representing the 3,890,000 Common Shares subject to the Put Option, less 479,108 Common Shares previously sold by NH on the open market, for an aggregate purchase price of KRW 24,500,000,000.  Mr. Huh will purchase (i) 2,980,892 Commons Shares from NH for KRW 21,566,000,000 and (ii) 430,000 Common Shares from NH’s affiliated fund for a purchase price equal to the USD-converted amount of KRW 2,934,000,000.
