CY2024	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements in accordance with U.S. GAAP requires our management to make certain estimates that affect reported amounts. We base our estimates on historical experience, known or expected trends, independent valuations, and various other assumptions that we believe to be reasonable under the circumstances. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.
