CY2023	us-gaap	Use Of Estimates UseOfEstimates	Use of Estimates The preparation of financial statements in conformity with the generally accepted accounting principles (“GAAP”) in the United States requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The accounting policies that we deem most critical to us and that require management’s most difficult and subjective judgments include the principles of consolidation, the recoverability of property, plant and equipment, the adequacy of insurance reserves, the recognition and measurement of impairments for investments accounted for under ASC 320 - Investments - Debt and Equity Securities and the recognition and measurement of income tax assets and liabilities. The actual results experienced by us may materially differ from management’s estimates.
