Form 40-F for Fiscal Year Ended December 31, 2018

2. Significant accounting policies
n) Revenue Recognition, page 56

1.     Based on the information provided in your correspondence dated December
3, 2019 and
       January 21, 2020 and a telephone conversation on February 19, 2020, we
believe your
       conclusion that you are acting as an agent for the sale of Atlas'
methanol and the resulting
       recognition of revenue on a net basis is inconsistent with the guidance
in IFRS 15.33 and
       IFRS 15.B37. In this regard, we believe you obtain control of the
methanol produced at
       the Atlas facility before that methanol is transferred to the customer.
Please restate your
       financial statements to recognize revenue for the sale of the methanol
produced by Atlas
       on a gross basis. Please also reconsider management's assessment of the
effectiveness of
       internal controls over financial reporting and disclosure controls and
procedures in light of
       the restatement.

       You may contact Tracey Houser, Staff Accountant, at (202) 551-3736, or
