The preparation of the accompanying unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and reported amounts of revenues and expenses during the reporting period. These estimates may change as new events occur and additional information is obtained, and will be recognized in the period in which such changes occur. Future actual results could differ materially from these estimates.
Recently adopted accounting pronouncements	Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in the existing guidance and making other minor improvements.
