	99.1		The Registrant’s Press Release dated October 28, 2003.

This press release is being furnished pursuant to Item 12 of this Current Report on Form 8-K and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that Section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act.

Item 12. Disclosure of Results of Operations and Financial Condition.

The attached press release includes information with respect to the Registrant’s operating earnings, operating earnings per share, operating net income and other operating results, all of which are non-GAAP financial measures. Management utilizes these non-GAAP financial measures to monitor and evaluate ongoing operating results and trends and to gain an understanding of the comparative operating performance of the Registrant. Management believes that these measures provide useful information to investors regarding the Registrant’s financial condition and results of operations because they exclude non-operational and unusual activities or transactions that are not necessarily relevant to an understanding of the Registrant’s business or the prospects for the Registrant’s future performance.
