Item 2.02.     Results of Operations and Financial Condition and

Item 7.01.     Regulation FD Disclosure

 On October 25, 2006, the Registrant issued a press release, attached hereto as Exhibit 99.  The press release, which reports third quarter results, includes a non-GAAP financial measure, as defined by SEC Regulation G, in the last sentence of the third paragraph, which is reconciled verbally within the release.  Specifically, the release excludes the effects of Ohio tax legislation from net income and diluted earnings per share for the first nine months of 2005 for the purposes of comparing it to net income and diluted earnings per share for the first nine months of 2006.   This measure should be considered in addition to, not as a substitute for, net income and diluted earnings per share reported in accordance with U.S. Generally Accepted Accounting Principles.  Management believes that net income and diluted earnings per share excluding this item may be more indicative of operating results for comparison to prior periods and to other companies and it intends to use this non-GAAP financial measure for comparison purposes at its analysts' meeting scheduled today and in future comparisons to the second quarter of 2005.
