Berkshire Hathaway Posts Record $381.67 Billion Cash Reserves in Q3

The assessment is primarily based on the highest authority and most relevant source provided: the official Berkshire Hathaway press release concerning its third-quarter earnings. The summary for this source explicitly states it is the primary document needed to verify the financial claim. The statement provides a highly specific figure ($381.67 billion), which is characteristic of data taken directly from a financial report. The presence of other high-authority sources like Yahoo Finance, which typically aggregate this exact type of official data, lends further credence to the claim's verifiability. Most of the other sources are irrelevant as they are either forward-looking (published before the results were released) or about different companies. There is one minor contradiction from a very low-authority Facebook post, but its different figure and lack of a specified time period make it unreliable. Therefore, the evidence strongly supports that the statement is an accurate figure derived from the official Q3 report.
