Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	Basis of Presentation and Accounting Policies Basis of Presentation The accompanying condensed consolidated balance sheet as of September 30, 2013, the related condensed consolidated statements of income and comprehensive income for the three and nine months ended September 30, 2013 and 2012, and the condensed consolidated statements of cash flows for the nine months ended September 30, 2013 and 2012, of Flowserve Corporation are unaudited. In management’s opinion, all adjustments comprising normal recurring adjustments necessary for a fair presentation of such condensed consolidated financial statements have been made. The accompanying condensed consolidated financial statements and notes in this Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2013 ("Quarterly Report") are presented as permitted by Regulation S-X and do not contain certain information included in our annual financial statements and notes thereto. Accordingly, the accompanying condensed consolidated financial information should be read in conjunction with the consolidated financial statements presented in our Annual Report on Form 10-K for the year ended December 31, 2012 ("2012 Annual Report"). On May 23, 2013, our certificate of incorporation was amended to increase the number of authorized shares of common stock from 120.0 million to 305.0 million and enable a three-for-one stock split approved by the Board of Directors on February 7, 2013 in the form of a 200% common stock dividend. The record date for the stock split was June 7, 2013, and additional shares were distributed on June 21, 2013. Shareholders' equity and all share data, including treasury shares and stock-based compensation award shares, and per share data presented herein have been retrospectively adjusted to reflect the impact of the increase in authorized shares and the stock split, as appropriate. Venezuela – As previously disclosed in our 2012 Annual Report, effective February 13, 2013, the Venezuelan government devalued its currency (bolivar) from 4.3 to 6.3 bolivars to the United States ("U.S.") dollar. Our operations in Venezuela generally consist of a service center that performs service and repair activities. In addition, certain of our operations in other countries sell equipment and parts that are typically denominated in U.S. dollars directly to Venezuelan customers. Our Venezuelan subsidiary's sales for the three and nine months ended September 30, 2013 and total assets at September 30, 2013 represented less than 1% of consolidated sales and total assets for the same periods. As a result of the devaluation, we recognized a loss of $4.0 million in the first quarter of 2013. The loss was reported in other expense, net in our condensed consolidated statements of income and resulted in no tax benefit. We have evaluated the carrying value of related assets and concluded that there is no current impairment. We are continuing to assess and monitor the ongoing impact of the currency devaluation on our Venezuelan operations and imports into the market, including our Venezuelan subsidiary's ability to remit cash for dividends and other payments at the official rate, as well as further actions of the Venezuelan government and economic conditions that may adversely impact our future consolidated financial condition or results of operations. Accounting Policies Significant accounting policies, for which no significant changes have occurred in the nine months ended September 30, 2013, are detailed in Note 1 to our consolidated financial statements included in our 2012 Annual Report. Accounting Developments Pronouncements Implemented In December 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-11, "Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities," which requires enhanced disclosures about financial instruments and derivative instruments that are either (1) offset in accordance with either Accounting Standards Codification ("ASC") 210-20-45, "Balance Sheet - Offsetting," or ASC 815-10-45, "Derivatives and Hedging - Overall," or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with either ASC 210-20-45 or ASC 815-10-45. The disclosure requirements shall be applied retrospectively for all periods presented. Our adoption of ASU No. 2011-11, effective January 1, 2013, had no impact on our consolidated financial condition and results of operations. In January 2013, the FASB issued ASU No. 2013-01, "Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities," which limits the scope of ASU 2011-11 to derivatives, repurchase agreements and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements shall be applied retrospectively for all periods presented. Our adoption of ASU No. 2013-01, effective January 1, 2013, had no impact on our consolidated financial condition and results of operations. In July 2012, the FASB issued ASU No. 2012-02, "Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment," which specifies that an entity has the option to first assess qualitative factors to determine whether it is more likely than not that the asset is impaired. Unless an entity determines that it is more likely than not that the fair value of such an asset is less than its carrying amount, it would not need to calculate the fair value of the asset in that year. Our adoption of ASU No. 2012-02, effective January 1, 2013, had no impact on our consolidated financial condition and results of operations. In February 2013, the FASB issued ASU No. 2013-02, "Comprehensive Income (Topic 220) - Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income," which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income. In addition, an entity is required 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. Generally Accepted Accounting Principles ("GAAP") to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. Our adoption of ASU No. 2013-02, effective January 1, 2013, had no impact on our consolidated financial condition and results of operations. In March 2013, the FASB issued ASU No. 2013-05, "Foreign Currency Matters (Topic 830) - Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity," which specifies that a cumulative translation adjustment should be released into earning when an entity ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity and the sale or transfer results in the complete or substantially complete liquidation of the foreign entity. ASU No. 2013-05 is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2013. We early adopted this ASU effective January 1, 2013 and it did not have a material impact on our consolidated financial condition and results of operations. In July 2013, the FASB issued ASU No. 2013-10, "Derivatives and Hedging (Topic 815) - Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes," which allows the use of the Fed Funds Effective Swap Rate as a U.S. benchmark interest rate for fair value and cash flow hedges under Topic 815, in addition to interest rates on direct Treasury obligations of the U.S. government and the London Interbank Offered Rate swap rate. This ASU also removes the restriction on using different benchmark rates for similar hedges. ASU No. 2013-10 is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. Our adoption of ASU No. 2013-10 did not have a material impact on our consolidated financial condition and results of operations. Pronouncements Not Yet Implemented In February 2013, the FASB issued ASU No. 2013-04, "Liabilities (Topic 405) - Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date," which requires a reporting entity that is jointly and severally liable to measure the obligation as the sum of the amount the entity has agreed with co-obligors to pay and any additional amount it expects to pay on behalf of one or more co-obligors. The scope of this ASU excludes obligations addressed by existing guidance. ASU No. 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The ASU shall be applied retrospectively for arrangements existing at the beginning of the year of adoption. Our adoption of ASU No. 2013-04 will not have an impact on our consolidated financial condition and results of operations. In April 2013, the FASB issued ASU No. 2013-07, "Presentation of Financial Statements (Topic 205) - Liquidation Basis of Accounting," which requires an entity to prepare its financial statements using the liquidation basis of accounting when liquidation is imminent. Liquidation is imminent when the likelihood is remote that the entity will return from liquidation and either (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective and the likelihood is remote that the execution of the plan will be blocked by other parties or (b) a plan for liquidation is being imposed by other forces (for example, involuntary bankruptcy). ASU No. 2013-07 is effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. The ASU shall be applied prospectively from the day that liquidation becomes imminent. Our adoption of ASU No. 2013-07 will not have an impact on our consolidated financial condition and results of operations. In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists," which provides guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The ASU shall be applied prospectively to all unrecognized tax benefits that exist at the effective date. The adoption of ASU No. 2013-11 will not have a material impact on our consolidated financial condition and results of operations.
