Our report dated March 27, 2020 refers to a change in accounting policies for leases as of January 1, 2019 due to the adoption of ASU 2016-02 – Leases, Revenue from Contracts with Customers (Topic 606), and related amendments.

Our report dated March 27, 2020 also contains and explanatory paragraph that states that the Company has suffered recurring losses and negative cash flows from operations, which raise substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
