Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	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 accounting principles generally accepted in the United States of America applicable to interim financial information and 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 nine months ended September 30, 2015 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 set forth in this report should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Recently Adopted Accounting Standards In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, which includes amendments that change the requirements for reporting discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations with a major effect on the organization’s operations and financial results should be presented as discontinued operations. Additionally, the ASU requires expanded disclosures about disposal transactions that do not meet the discontinued operations criteria. The Company adopted the standard effective January 1, 2015. Recently Issued Accounting Standards In May 2014, FASB ASU 2014-09 was issued, which introduces a new five-step revenue recognition model. Under ASU 2014-09, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This standard was initially released as effective for fiscal years beginning after December 15, 2016; however, in July 2015 the FASB approved a one year deferral of this standard, with a new effective date for fiscal years beginning after December 15, 2017. The new guidelines can be implemented using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption. The Company is currently evaluating the impact of the new guidance on our consolidated financial statements and has not yet determined the method by which we will adopt the standard. In April 2015, the FASB issued ASU 2015-03 which simplifies the presentation of debt issuance costs. Under ASU 2015-03, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs is reported as interest expense. This standard is effective for fiscal years beginning after December 15, 2015. The Company is currently evaluating the impact of the new guidance on our consolidated financial statements and does not expect it to have a material impact on the consolidated financial position, results of operations or cash flows of the Company.
