¹ Personal auto insurance accounted for 92% of the total Personal Lines segment net premiums earned in 2014, compared to 91% in 2013 and 2012; insurance for our special lines products (e.g., motorcycles, ATVs, RVs, mobile homes, watercraft, and snowmobiles) accounted for the balance of the Personal Lines net premiums earned.

² Pretax profit (loss) for fees and other revenues are allocated to operating segments.

³ Revenues represent recurring investment income and total net realized gains (losses) on securities; pretax profit is net of investment expenses.
