The second and last stage, included the construction of the surface installations needed for the processing, guarding, injection, extraction and transportation of LPG, completed in October of 2017. The commercial operations of processing and underground storage of LPG for Pemex started on November 16, 2017.

The Company drew down 950 million at a three year term, without real guaranties, nor mandatory amortizations of the principal amount. With these proceeds, CYDSA paid all then existing peso denominated loans. In summary, at the close of the first quarter of 2018, the Group s Debt consist of: 1) Senior Notes maturing in ten years for US$330 million; and 2) Syndicated Revolving Loan at three year term, in the amount of 950 million pesos.

This instrument covers the risk of an exchange rate above 20.50 pesos per dollar, without margin call requirements or additional disbursements to the amount already paid. In addition, on October 10 of 2017, CYDSA acquired an exchange coverage to protect an additional amount of US$50.0 million dollars, maturing on September 12, 2018.
