during the first quarter this year, compared to 1.0 points for the same period

in all lines of our business during the first quarter. Our responsible pricing
and disciplined underwriting strategies continued to produce outstanding
combined ratios, allowing us to build shareholder value. STFC has produced
record quarterly net operating earnings* in eight of the last ten quarters. We

is informative to Company management and investors, differ from GAAP net income
only by the




exclusion of realized capital gains and losses, net of applicable taxes, on
investment activity for the periods being reported. For STFC, this amounts to
$0.04 per diluted share for the first quarter 2005 versus $0.09 for the same
2004 period.
