         (i.e., Trinidad, New Zealand, Chile, Egypt), please provide a detailed
description of the
         following:

              A breakdown of the consumers for natural gas and the approximate
percentage of
              natural gas used by each. For example, you indicated that in
Southern
              Chile approximately 50% of the natural gas supply is used for
domestic residential
              and commercial/industrial electricity needs and you use the
remaining 50% of the
              natural gas supply. Please help us understand the types of gas
consumers and their
              proportionate consumption in the other regions.

              The pricing structure of gas supply contracts with gas consumers
other than you in
              each of these regions to the extent you are aware. Please tell us
the cost drivers of
              natural gas in these regions and how this compares to the portion
of the natural gas
              market that you occupy.

              The number and type of natural gas suppliers from whom you
purchase natural gas.
              Please describe any differences in how you negotiate with the
different types of
              suppliers (government owned versus private owners) and tell us
whether there are
              any material differences in key contract terms between the types
of suppliers.
3.       For regions in which there are other methanol producers (e.g.,
Trinidad), please tell us if
         those entities' gas supply contracts are also linked to the price of
methanol. If not, please
         provide information on how those natural gas supply contracts are
priced.
4.       Please describe how you evaluated whether the economic characteristics
and risks of the
         variable price component are closely related to the economic
characteristics and risks of
         the natural gas supply contract. Please refer to IFRS 9 4.3.3(a) for
guidance. To the
         extent the economics and risks are different among the jurisdictions
in which you operate,
         please provide this analysis for each location.
       You may contact Tracey Houser, Staff Accountant, at (202) 551-3736, or
Terence O'Brien, Accounting Branch Chief, at (202) 551-3355, if you have
questions regarding
comments on the financial statements and related matters.
