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 three and six months ended June 30, 2013 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, 2012. *Adoption of New Accounting Standards* In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02 which requires additional disclosures regarding the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 requires an entity to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. This guidance is effective for reporting periods beginning after December 15, 2012. The Company adopted this guidance effective January 1, 2013 and its adoption did not impact the consolidated financial position, results of operations or cash flows of the Company. See Note 13 for a further discussion on other comprehensive income (loss). *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” 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. The Company does not expect ASU 2012-02 to have a material impact on the consolidated financial position, results of operations or cash flows of the Company.
