2. ACCOUNTING POLICIES

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts and related disclosures. We have discussed those estimates that we believe are critical and require the use of complex judgment in their application in our audited financial statements for the year ended December 31, 2020 in our Annual Report on Form 10-K filed with the SEC, on March 11, 2021. Since December 31, 2020, there have been no material changes to our critical accounting policies or the methodologies or assumptions we apply under them.
