Premiums Written by Segment
Breaks down premiums written by business line (e.g., property-casualty, reinsurance, auto), showing which segments drive growth and how diversified the insurance portfolio is. Helps spot concentration risk, shifts in strategy, and areas where underwriting or competitive dynamics may affect future earnings.Geico is the clear growth engine—steady, compound-like premium expansion that is likely enlarging Berkshire’s insurance float and underwriting scale. Berkshire Primary Group shows disciplined, incremental growth with recurring Q4 softening, consistent with commercial renewal patterns. Property & Casualty is the most volatile, with sharp quarter-to-quarter swings that suggest renewal timing, rate volatility or catastrophe exposure. For investors, rising premiums improve capital deployment optionality but don’t guarantee profitability—watch combined ratios, reserve development and catastrophe trends to judge earnings quality.
