<u>Comment No. 17</u>

***We note your disclosure related to the gain recognized on your Blue Chip Swap arrangements. You state that you acquire and transfer marketable securities of large, well established companies with high trading volumes and low volatility as part of these transactions and that this strategy improves cash management for funding your Argentinian subsidiary. Please address the following points:***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***provide your accounting policy for these transactions, identifying the specific authoritative guidance that you are following,*** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***tell us where the marketable securities are captured on your balance sheet and where the purchases and sales of these marketable securities are captured in your statement of cash flows, and*** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***clarify how you calculate the foreign currency gains on these transactions and identify the amounts that are realized and unrealized for each of the periods presented.*** 

<u>Response</u>

With respect to the disclosure of the Blue Chip Swap arrangements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Company's accounting policies in respect of the Blue Chip Swap arrangements follow accounting
policies stated in our Form 10-K filed on March 7, 2022 for the fiscal year ended December 31, 2021, under the heading *Investments* on page 86 of that Form 10-K as well as *Foreign Currency* on page 90. We follow the guidance set
out in ASU 2016-01, *Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities*, as well as ASC 830, *Foreign Currency Matters*. The Company purchases securities on US exchanges using US Dollars.
These securities are swapped for equivalent securities on Argentinean exchanges known as CEDEARs which are denominated in Argentine Pesos,
and on the sale of the CEDEARs the Company receives Argentine Pesos. On the settlement of our Blue Chip Swap arrangements, a gain or loss
on investment is recognized on the realized fair value change in the marketable securities, as well as a gain or loss on foreign exchange;
the calculation of gain or loss on foreign exchange is further described below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The marketable securities relating to Blue Chip Swaps are not captured on our balance sheet as of September 30,
2022, as no marketable securities relating to Blue Chip Swaps were outstanding at the end of the period. The cash inflows and outflows
of the sales of these marketable securities, including the foreign exchange impact, are reported in cash flows from operations, under
the Net Income heading.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Foreign currency gains or losses on transactions are calculated by comparing the realized amount of Argentine
Pesos yielded through the Blue Chip Swap arrangement against the spot USD/ARG Official Exchange Rate determined by the Argentine Central
Bank on the date of settlement. As all transactions were fully settled as of September 30, 2022, all amounts presented in our financial
statements are realized, with nil unrealized value. No Blue Chip Swap arrangements were completed in prior comparative periods.
