OTHER EVENTS - ------------------------ On December 17, 2004, SPX Corporation (the "Company") issued a press release announcing that updated business segment information has changed the Company's expectations for 2004 results. A copy of the press release is attached as Exhibit 99.1 hereto and incorporated herein by reference. The press release incorporated by reference into this Item 8.01 contains disclosure regarding free cash flow, which is defined as net cash from operating activities less capital expenditures. The Company's management believes that free cash flow can be a useful financial measure for investors in evaluating the cash flow performance of multi-industrial companies, since it provides insight into the amount of cash available to fund such things as equity repurchases, dividends, debt reduction and acquisitions or other strategic investments. In addition, free cash flow is one of the factors used by the Company's management in internal evaluations of the overall performance of the business. Free cash flow, however, is not a measure of financial performance under GAAP, should not be considered a substitute for cash flows from operating activities as determined in accordance with GAAP as a measure of liquidity, and may not be comparable to similarly titled measures reported by other companies. In addition, free cash flow is not a direct measure of cash flow available for discretionary spending, since non-discretionary expenditures, such as debt service, are not deducted from free cash flow.
