Net earnings attributable to Berkshire shareholders in the last quarter came in $32,551 million versus $6,286 million in Q4 2016. For 2017 as a whole the figure stood at $44,940 million (2016: $24,074 million). For the full year, Berkshire posted $44.9 billion in net income, equivalent to $18.22 per Class B share. These storms largely explain why Berkshire’s insurance underwriting posted a loss in 2017 following 14 years of consecutive underwriting profits. And, the compounded annual gain between 1965 and 2017 was 20.9% for Berkshire versus 9.9% on the S&P 500.
