(3) Under existing Generally Accepted Accounting Principles, unrealized gains and losses on equity security investments are required to be included in earnings. Accordingly, due to the large size of Berkshire’s equity investment portfolio and the volatility in equity markets there can be significant volatility in Berkshire’s periodic net earnings. (4) Berkshire does not use any financial performance measure in setting the compensation of its PEO (Principal Executive Officer) or for its NEOs (Non-PEO named executive officers).
