For the full year of 2012, operating income in our Traditional Insurance segment increased year-over-year largely due to improved profitability in the Medicare Supplement business. Operating income for the fourth quarter of 2012 declined year-over-year due to a higher MBR on our long-term care business combined with the continued decline in business-in-force. Revenue declined in both the three month and full year periods ended December 31, 2012 due to the continued run-off of our legacy insurance products.
