*Average diluted shares outstanding and net income per share amounts for the
three and six months ended June 30, 2004 have been restated, as required,
in accordance with Emerging Issues Task Force (EITF) 04-8 "The Effect
of Contingently Convertible Debt on Diluted Earnings Per Share." This EITF
requires earnings per share amounts for periods prior to December 31, 2004
be restated since the issuance of the convertible notes in March 2002
using the "if-converted" method. The "if-converted" method gives effect to
the add back to net income of interest expense and amortization of debt
issuance costs, net of tax, associated with the convertible instruments.

**Management of the Corporation believes the significant volatility of
realized investment gains and losses limits the usefulness of net income as
a measure of current operating performance. Accordingly, management uses the
non-GAAP financial measure of operating income to further evaluate current
operating performance. Operating income return on equity is calculated by
dividing the annualized consolidated operating income for the most recent
quarter by the average shareholders' equity for the quarter using a simple
average of beginning and ending balances for the quarter, excluding from
equity after-tax unrealized investment gains and losses. See press release
dated July 26, 2005 for reconciliation of operating income both in dollar
amounts and per share amounts and operating income return on equity to net
income, net income per share and net income return on equity, respectively.
