Basis of Presentation and Responsibility for Interim Financial Statements

Basis of Presentation and Responsibility for Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements of Pentair Ltd. and subsidiaries (“we,” “us,” “our,” “Pentair,” or “the Company”) have been prepared following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America can be condensed or omitted.

We are responsible for the unaudited financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2012.

Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year.

Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week basis ending on a Saturday.

New Accounting Standards

In February 2013, the Financial Accounting Standards Board issued authoritative guidance surrounding the presentation of items reclassified from Accumulated other comprehensive income (loss) (“AOCI”) to net income. This guidance requires entities to disclose, either in the notes to the consolidated financial statements or parenthetically on the face of the statement that reports comprehensive income, items reclassified out of AOCI and into net income in their entirety and the effect of the reclassification on each affected net income line item. In addition, for AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required disclosures is required. This guidance was effective for fiscal years and interim periods beginning after December 15, 2012. The adoption of this guidance on January 1, 2013 did not impact our financial condition or results of operations. The reclassifications out of AOCI and into net income were not material for the three and six months ended June 29, 2013.
