1.    Basis of Presentation and Significant Accounting Policies

The Condensed Consolidated Financial Statements of IDEX Corporation (“IDEX” or the “Company”) have been prepared in accordance with the instructions to Form 10-Q under the Securities Exchange Act of 1934, as amended. The statements are unaudited but include all adjustments, consisting only of recurring items, except as noted, that the Company considers necessary for a fair presentation of the information set forth herein. The results of operations for the nine months ended September 30, 2012 are not necessarily indicative of the results to be expected for the entire year.

The condensed consolidated financial statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011.

Adoption of New Accounting Standards

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04, “Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS” (“ASU 2011-04”), which was issued to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles (“GAAP”) and International Financial Reporting Standards (“IFRS”). ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. The Company adopted this guidance on January 1, 2012, and its adoption did not impact the consolidated financial position, results of operations or cash flows of the Company.

In June 2011, FASB issued ASU 2011-05 “Presentation of Comprehensive Income.” ASU 2011-05 allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, FASB issued ASU 2011-12 “Comprehensive Income (Topic 220); Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-12 deferred certain aspects of ASU 2011-05. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-05 and the deferrals in ASU 2011-12 did not impact the consolidated financial position, results of operations or cash flows of the Company.

New Accounting Pronouncements

In July 2012, the FASB issued ASU 2012-02, “Intangibles — Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment” (ASU 2012-02), which allows an entity to first assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test of an indefinite-lived intangible asset. Under ASU 2012-02, an entity would not be required to calculate the fair value of an indefinite-lived intangible asset if the entity determines, based on qualitative assessment, that it is not more likely than not impaired. The revised standard is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012; however, early adoption is permitted. As of September 30, 2012, the Company did not elect to early adopt ASU 2012-02; however, the Company may elect to early adopt prior to its annual test date. ASU 2012-02 is not expected to have a material impact on the consolidated financial position, results of operations or cash flows of the Company.

The allocation of the acquisition costs to the assets acquired and liabilities assumed, based on their estimated fair values, is as follows:

Acquired intangible assets consist of trade names, non-compete agreements, customer relationships and unpatented technology. The goodwill recorded for the acquisitions reflects the strategic fit and revenue and earnings growth potential of these businesses.
