Item 9.01   Financial Statements and Exhibits.

     (c)  Exhibits

          99.1 Press Release of the Company, dated May 5, 2005.

Use of Non-GAAP Financial Information

The Company's press release, and other communications from time to time, include
certain non-GAAP financial measures. A "non-GAAP financial measure" is defined
as a numerical measure of a company's financial performance, financial position
or cash flows that excludes (or includes) amounts that are included in (or
excluded from) the most directly comparable measure calculated and presented in
accordance with GAAP in the Company's financial statements.

The attached press release utilizes a measure of free cash flow. Free cash flow
is defined as operating cash flow less capital expenditures. The Company's
management believes that although free cash flow does not represent the amount
of money available for the Company's discretionary spending because certain
obligations of the Company must be funded out of free cash flow, it nevertheless
provides a useful measure of liquidity for assessing the amount of cash
available for general corporate and strategic purposes after funding operating
activities and capital expenditures, and deferred costs.

In addition, return on invested capital, also included in the attached press
release, is a non-GAAP financial measure. Management defines "return on invested
capital" as net income, less investment income plus tax paid on investment
income. Invested capital is calculated as average total assets (over a trailing
four-quarter period), less average cash and short term investments (over a
trailing four-quarter period), less average non-interest bearing current
liabilities (over a trailing four-quarter period). Management believes that
return on invested capital is useful because it provides investors with
additional useful information for evaluating the efficiency of the Company's
capital deployed in its operations. Return on invested capital does not consider
whether the business is financed with debt or equity, but rather calculates a
return on all capital invested in the business.

The non-GAAP financial measures used by the Company in the attached press
release may not be comparable to similarly titled measures used by other
companies and should not be considered in isolation or as a substitute for
measures of performance or liquidity prepared in accordance with GAAP.
