ITEM 2.02 Results of Operations and Financial Condition
On April 21, 2009, Pentair, Inc. (the "Company") issued a press release announcing its earnings for the first quarter of 2009 and a conference call in connection therewith. A copy of the release is furnished herewith as Exhibit 99.1 and incorporated herein by reference.
This press release refers to certain non-GAAP financial measures (adjusted operating income, adjusted operating margins, adjusted earnings per share and free cash flow) and a reconciliation of those non-GAAP financial measures to the corresponding financial measures contained in the Company's financial statements prepared in accordance with generally accepted accounting principles. Adjusted operating income, adjusted operating margins and adjusted earnings per share eliminate certain expenses incurred in the first quarter of 2009 to restructure certain operations of the Company by reducing headcount as a result of the significant continuing downturn in the global economy. Management utilizes these adjusted financial measures to assess the run-rate of its continuing operations against those of prior periods without the distortion of these factors. The Company believes that these non-GAAP financial measures will be useful to investors as well to assess the continuing strength of the Company's underlying operations in light of the downturn in the residential end markets.
The Company uses free cash flow and conversion of income from continuing operations to assess its cash flow performance. The Company believes free cash flow and conversion of income from continuing operations are important measures of operating performance because they provide the Company and its investors a measurement of cash generated from operations that is available to pay dividends and repay debt. In addition, free cash flow and conversion of income from continuing operations are used as a criterion to measure and pay compensation-based incentives. The Company's measure of free cash flow and conversion of income from continuing operations may not be comparable to similarly titled measures reported by other companies.
The information contained in this Current Report shall not be deemed to be "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 incorporated by reference into a filing under the Securities Act of 1933, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
