Pronouncements Implemented

In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," (the "New Revenue Standard" or "ASC 606"), which supersedes most of the revenue recognition requirements in "Revenue Recognition (Topic 605)." The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue when (or as) it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services.("Topic 605"). On January 1, 2018, we adopted the new revenue standardNew Revenue Standard using the modified retrospective method for transition, applying the guidance to those contracts which were not completed as of that date. According to our method of transition we adjusted for the cumulative effect of the changes made to our condensed consolidated balance sheet and recorded a cumulative effect adjustment to increase retained earnings by $20.0approximately $20 million, mostly associated with the increase in percentage of completion ("POC") method revenue, as a result of initially applying the standard. We have modified our accounting policies and practices, business processes, systems and controls to support compliance with the standard requirements. Revenue recognition and related financial information for this Quarterly Report are based on the requirements of ASC 606. Accordingly, periods prior to January 1, 2018 are presented in accordance with ASC Topic 605. Refer to Note 2 of this Quarterly Report for a discussion on our adoption of the New Revenue Standard.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The ASU requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value with changes in fair value recognized in net income. The ASU also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The requirement to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost on the balance sheet has been eliminated by this ASU. In February 2018, the FASB issued ASU No. 2018-03, "Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10)" to clarify certain aspects of ASU No. 2016-01. Our adoption of ASU No. 2016-01 and ASU No. 2018-03 effective January 1, 2018 did not have an impact on our consolidated financial condition and results of operations.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments - A consensus of the FASB Emerging Issues Task Force.” The update was issued with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230 and other topics. Our adoption of ASU No. 2016-15 effective January 1, 2018 did not have a material impact on our consolidated statement of cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740) Intra-Entity Transfers of Assets Other Than Inventory." The ASU guidance requires the recognition of the income tax consequences of an intercompany asset transfer, other than transfers of inventory, when the transfer occurs. For intercompany transfers of inventory, the income tax effects will continue

to be deferred until the inventory has been sold to a third party. Our adoption of ASU No. 2016-16 effective January 1, 2018 did not have a material impact on our consolidated financial condition and results of operations.

In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash." The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Our adoption of ASU No. 2016-18 effective January 1, 2018 did not have a material impact on our consolidated statement of cash flows.

In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): "Clarifying the Definition of a Business." The ASU clarifies the definition of a business and provides guidance on evaluating as to whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition clarification as outlined in this ASU affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. Our adoption of ASU No. 2017-01 effective January 1, 2018 did not have a material impact on our consolidated financial condition and results of operations.

In February 2017, the FASB issued ASU No. 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." The FASB issued this ASU to clarify the scope of subtopic 610-20, which the FASB had failed to define in its issuance of ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." We adopted ASU No. 2017-05 effective January 1, 2018, concurrently with ASU No. 2014-09. Our adoption of ASU No. 2017-05 effective January 1, 2018 did not have a material impact on our consolidated financial condition and results of operations.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The ASU requires entities to disaggregate the current service cost component from the other components of net benefit cost and present it with other current compensation costs for related employees in the income statement and present the other components of net benefit cost elsewhere in the income statement and outside of operating income. Entities are required to retrospectively apply the requirement for a separate presentation in the income statement of service costs and other components of net benefit cost. We adopted the income statement presentation aspects of this new guidance on a retrospective basis during the three months ended March 31, 2018.basis. The following is a reconciliation of the effect of the reclassification of the net post-retirement benefit cost from cost of sales ("COS") and selling, general and administrative expenses ("SG&A"), to other expense, net in our condensed consolidated statement of income for the three and six months ended March 31,June 30, 2017:

In May 2017, the FASB issued ASU No. 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting." The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards, to which an entity would be required to apply modification accounting. The ASU is applied prospectively to awards modified on or

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The ASU requires, among other things, the use of a new current expected credit loss ("CECL") model in order to determine our allowances for doubtful accounts with respect to accounts receivable and contract assets. The CECL model requires that we estimate our lifetime expected credit loss with respect to our receivables and contract assets and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors that influenced our estimate of expected credit losses and the reasons for those changes. The amendments of the ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are currently evaluating the impact of ASU No. 2016-13 on our consolidated financial condition and results of operations.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." The amendments in this ASU allow companies to apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The amendments of the ASU are effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact of ASU No. 2017-04 on our consolidated financial condition and results of operations.

On July 13, 2017, the FASB issued ASU No. 2017-11, “Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatory Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatory Redeemable Noncontrolling Interests with a Scope Exception.” The ASU amends guidance in FASB Accounting Standards Codification ("ASC") 260, Earnings Per Share, FASB ASC 480, Distinguishing Liabilities from Equity, and FASB ASC 815, Derivatives and Hedging. The amendments in Part I of this ASU change the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. The amendments in Part II of the ASU re-characterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending content in the codification, to a scope exception. The amendments in this ASU must be applied to annual reporting periods beginning after December 15, 2018. Early adoption is permitted. We are currently evaluating the impact of ASU No. 2017-11 on our consolidated financial condition and results of operations.

On August 28, 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted improvements of Accounting for Hedging Activities." The purpose of this ASU is to better align a company’s risk management activities and financial reporting for hedging relationships. Additionally, the ASU simplifies the hedge accounting requirements and improve the disclosures of hedging arrangements. The effective date is fiscal year 2020, with early adoption permitted. We are currently evaluating the impact of ASU No. 2017-12 on our consolidated financial condition and results of operations.

We enter into contracts with customers typically having multiple commitments of goods and services including any combination of designing, developing, manufacturing, modifying, installing and commissioning of flow management equipment and providing services and parts related to the performance of such products. We evaluate the commitments in our contracts with customers to determine if the commitments are both capable of being distinct and distinct in the context of the contract in order to identify performance obligations.

We recognize revenue when (or as) we satisfy a performance obligation by transferring control of the performance obligation to a customer. Control of a performance obligation may transfer to the customer either over time or at a point in time depending on an evaluation of the specific facts and circumstances for each contract, including the terms and conditions of the contract as

Control transfers over time when the customer is able to direct the use of and obtain substantially all of the benefits of our work as we perform. This typically occurs when products have no alternative use and we have a right to payment for performance completed to date, including a reasonable profit margin. Our contracts often include cancellation provisions that require the customer to reimburse us for costs incurred up to the date of cancellation, and some contracts also provide for reimbursement of profit upon cancellation in addition to costs incurred to date.

Our primary method for recognizing revenue over time is the POC method.  We measure progress towards completion by applying an input measure based on costs incurred to date relative to total estimated costs at completion (i.e., the cost-to-cost method).  This method provides a reasonable depiction of the transfer of control of products and services to customers as it ensures our efforts towards satisfying a performance obligation, as reflected by costs incurred, are included in the measure of progress used for recognition of revenue. Costs generally include direct labor, direct material and manufacturing overhead.  Costs that do not contribute towards control transfer are generally immaterial, but are excluded from the measure of progress in the event they are significant.

Historically, revenue recognized under the POC method has been 5% to 10% of our consolidated sales. Under the New Revenue Standard, we have experienced an increase in the amount of revenue recognized over time.  This increase is primarily due to the application of the new “transfer of control” model for revenue recognition. Under this model, revenue for performance obligations subject to contractual transfer of control during the manufacturing process must beare recognized over time. This includes contracts with cancellation provisions that require reimbursement for costs incurred plus a reasonable margin and for which the performance obligation has no alternative use.  Revenue from products and services transferred to customers over time accounted for approximately 23% and 3% of total revenue for the three month periods ended March 31,June 30, 2018 and 2017, respectively, and 23% and 3% of total revenue for the six month periods ended June 30, 2018 and 2017, respectively.

If control does not transfer over time, then control transfers at a point in time. We recognize revenue at a point in time at the level of each performance obligation based on the evaluation of certain indicators of control transfer, such as title transfer, risk of loss transfer, customer acceptance and physical possession. Revenue from products and services transferred to customers at a point in time accounted for approximately 77% and 97% of total revenue for the three month periods ended March 31,June 30, 2018 and 2017, respectively, and 77% and 97% of total revenue for the six month periods ended June 30, 2018 and 2017, respectively.

A contract modification, or “change order,” occurs when the existing enforceable rights and obligations of a contract change, such as a change in the scope, price or terms and conditions. We account for a change order as a new accounting contract when the change order is limited to adding new, distinct products and services that are priced in an amount consistent with standalone selling price. Other change orders are accounted for as a modification of the existing accounting contract. When a change order occurs for a contract having in-process over time performance obligations, the effect of the change order on the transaction price

Freight charges billed to customers are included in sales and the related shipping costs are included in cost of sales in our consolidated statements of income. If shipping activities are performed after a customer obtains control of a product, we apply a policy election to account for shipping as an activity to fulfill the promise to transfer the product to the customer.

We apply a policy election to exclude transaction taxes collected from customers from sales when the tax is both imposed on and concurrent with a specific revenue-producing transaction.

In certain instances, we provide guaranteed completion dates under the terms of our contracts. Failure to meet contractual delivery dates can result in late delivery penalties or liquidated damages. In the event that the transaction price of such a contract is probable of experiencing a significant reversal due to a penalty, we constrain a portion of the transaction price. This reduction to the transaction price could potentially cause estimated total contract costs to exceed the transaction price, in which case we record a provision for the estimated loss in the period the loss is first projected. In circumstances where the transaction price still exceeds total projected costs, the estimated penalty generally reduces profitability of the contract at the time of subsequent revenue recognition.

Our incremental costs to obtain a contract are limited to sales commissions. We apply the practical expedient to expense commissions as incurred for contracts having a duration of one year or less. Sales commissions related to contracts with a duration of greater than one year are immaterial to our financial statements and are also expensed as incurred.

We have not identified any material costs to fulfill a contract that qualify for capitalization under ASC 340-40.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account for recognition of revenue. Many of our contracts have multiple performance obligations as the promise to transfer the individual goods or services, or certain groups of goods and services, is separately identifiable from other promises in the contract.

We allocate the transaction price of each contract to the performance obligations on the basis of standalone selling price and recognize revenue when, or as, control of each performance obligation transfers to the customer. For standard products, we identify the standalone selling price based on directly observable information. For customized or unique products and services, we apply the cost plus margin approach to estimate the standalone selling price. Under this method, we forecast our expected costs of satisfying a performance obligation and then add an appropriate standalone market margin for that distinct good or service.

We have elected to use the practical expedient to not adjust the transaction price of a contract for the effects of a significant financing component if, at the inception of the contract, we expect that the period between when we transfer a promised good or service to a customer and when the customer pays for that good or service will be one year or less.

A material product warranty exists when a customer has specifically requested or negotiated a warranty period that is significantly longer than our standard warranty period (i.e., a “service-type warranty”) and where the warranty obligation is material in the context of the contract. It is not common for our contracts to contain material product warranties. However, when such a warranty exists, we account for it as a separate performance obligation. We estimate the standalone selling price of the warranty obligation utilizing a cost plus margin approach and allocate a portion of the transaction price to the warranty performance obligation on the basis of estimated standalone selling price. We recognize revenue for warranty performance obligations over time on a straight line basis over the extended warranty period.

A material right option is a benefit provided to a customer in a current contract, such as an option to receive future products or services for free or at a significant discount, that is incremental to benefits widely available to similar customers that do not enter into a specific contract. It is not common for our contracts to contain material right options. However, when a material right option exists, it is accounted for as a separate performance obligation and a portion of the transaction price is allocated to the performance obligation based on the estimated standalone selling price of the option. Revenue is recognized when (or as) the customer exercises the right to acquire future products and/or services.

On March 31,June 30, 2018, the aggregate transaction price allocated to unsatisfied (or partially unsatisfied) performance obligations was approximately $1,341$1,335 million. We estimate recognition of approximately $1,180$1,059 million of this amount as revenue in 2018 and an additional $161$276 million in 2019 and thereafter.

During the first quarter of 2018, revenueRevenue recognized for performance obligations satisfied (or partially satisfied) in prior periods for the three and six months ended June 30, 2018 was not material.

We applied ASC 606 only to contracts that were not substantially complete as of January 1, 2018 and reflected the aggregate impact of all contract modifications (“change orders”) that occurred before the beginning of the earliest period presented when accounting for modified contracts at transition. The following table presents the cumulative effect of the changes made to our condensed consolidated balance sheet as of January 1, 2018 related to the adoption of the New Revenue Standard:

The modified retrospective approach requires a dual reporting presentation to be disclosed in the year of adoption. The dual reporting requirement outlines the impact amount by which a financial statement line is affected in the current reporting period by the adoption of the New Revenue Standard as compared with the previous standard in effect before the adoption.

The following tables present the dual reporting requirements:

We conduct our operations through three business segments based on the type of product and how we manage the business:

Our revenue sources are derived from our original equipment manufacturing and our aftermarket sales and services. Our original equipment revenues are generally related to originally designed, manufactured, distributed and installed equipment that can range from pre-configured, short-cycle products to more customized, highly-engineered equipment ("Original Equipment"). Our aftermarket sales and services are derived from sales of replacement equipment, as well as maintenance, advanced diagnostic, repair and retrofitting services ("Aftermarket"). Each of our three business segments generate Original Equipment and Aftermarket revenues.

We receive payment from customers based on a contractual billing schedule and specific performance requirements as established in our contracts. We record billings as accounts receivable when an unconditional right to consideration exists. A contract asset represents revenue recognized in advance of our right to receive payment under the terms of a contract. A contract liability represents our right to receive payment in advance of revenue recognized for a contract.

The following table presents opening and closing balances of contract assets and contract liabilities, current and long-term, for the threesix months ended March 31,June 30, 2018:

We maintain the Flowserve Corporation Equity and Incentive Compensation Plan (the "2010 Plan"), which is a shareholder-approved plan authorizing the issuance of up to 8,700,000 shares of our common stock in the form of restricted shares, restricted share units and performance-based units (collectively referred to as "Restricted Shares"), incentive stock options, non-statutory stock options, stock appreciation rights and bonus stock. Of the 8,700,000 shares of common stock authorized under the 2010 Plan, 2,179,6832,187,671 were available for issuance as of March 31,June 30, 2018. In 2016 the long-term incentive program was amended to allow Restricted Shares granted after January 1, 2016 to employees who retire and have achieved at least 55 years of age and 10 years of service to continue to vest over the original vesting period ("55/10 Provision"). As of March 31,June 30, 2018, 114,943 stock options were outstanding, with a grant date fair value of $2.0 million, which is expected to be recognized over a weighted-average period of approximately two years. No stock options were granted orduring the six months ended June 30, 2018, compared to 114,943 stock options granted for the same period in 2017. No stock options vested during the threesix months ended March 31,June 30, 2018 and 2017, respectively.2017.

 Restricted Shares – Awards of Restricted Shares are valued at the closing market price of our common stock on the date of grant. The unearned compensation is amortized to compensation expense over the vesting period of the restricted shares, except for awards related to the 55/10 Provision which are expensed in the period granted. We had unearned compensation of $36.1$31.0 million and $16.7 million at March 31,June 30, 2018 and December 31, 2017, respectively, which is expected to be recognized over a weighted-average period of approximately two years.one year. These amounts will be recognized into net earnings in prospective periods as the awards vest. The total fair value of Restricted Shares vested during the three months ended March 31,June 30, 2018 and 2017 was $10.7$2.7 million and $25.7$2.3 million, respectively. The total fair value of Restricted Shares vested during the six months ended June 30, 2018 and 2017 was $33.7 million and $28.0 million, respectively.

We recorded stock-based compensation expense of $3.1$3.4 million ($4.04.4 million pre-tax) and $7.5$2.9 million ($11.34.3 million pre-tax) for the three months ended March 31,June 30, 2018 and 2017, respectively. We recorded stock-based compensation expense of $6.5 million ($8.4 million pre-tax) and $10.4 million ($15.6 million pre-tax) for the six months ended June 30, 2018 and 2017, respectively. Performance-based shares granted in 2015 did not vest due to unachievement of performance targets not being achieved resulting in 100,033 forfeited shares being forfeited and a $5.4 million reduction of stock-based compensation expense for the threesix months ended March 31,June 30, 2018.

The following table summarizes information regarding Restricted Shares:

Unvested Restricted Shares outstanding as of March 31,June 30, 2018 includesincluded approximately 775,000762,000 units with performance-based vesting provisions. Performance-based units are issuable in common stock and vest upon the achievement of pre-defined performance targets. Performance-based units granted prior to 2017 have performance targets based on our average annual return on net assets over a three-year period as compared with the same measure for a defined peer group for the same period. Performance-based units granted in 2017 and 2018 have performance targets based on our average return on invested capital and our total shareholder return ("TSR") over a three-year period. Most units were granted in three annual grants since January 1, 2016 and have a vesting percentage between 0% and 200% depending on the achievement of the specific performance targets. Except for shares granted under the 55/10 Provision, compensation expense is recognized ratably over a cliff-vesting period of 36 months, based on the fair value of our common stock on the date of grant, as adjusted for actual forfeitures. During the performance period, earned and unearned compensation expense is adjusted based on changes in the expected achievement of the performance targets for all performance-based units granted except for the TSR-based units. Vesting provisions range from 0 to approximately 1,546,0001,523,000 shares based on performance targets. As of March 31,June 30, 2018, we estimate vesting of approximately 624,000610,000 shares based on expected achievement of performance targets.

Our risk management and foreign currency derivatives and hedging policy specifies the conditions under which we may enter into derivative contracts. See Notes 1 and 67 to our consolidated financial statements included in our 2017 Annual Report and Note 67 of this Quarterly Report for additional information on our derivatives. We enter into foreign exchange forward contracts to hedge our cash flow risks associated with transactions denominated in currencies other than the local currency of the operation engaging in the transaction.

Foreign exchange contracts with third parties had a notional value of $272.1$287.2 million and $235.6 million at March 31,June 30, 2018 and December 31, 2017, respectively. At March 31,June 30, 2018, the length of foreign exchange contracts currently in place ranged from 313 days to 2127 months.

We are exposed to risk from credit-related losses resulting from nonperformance by counterparties to our financial instruments. We perform credit evaluations of our counterparties under foreign exchange contracts agreements and expect all counterparties to meet their obligations. We have not experienced credit losses from our counterparties.

The fair values of foreign exchange contracts are summarized below:

Current and noncurrent derivative assets are reported in our condensed consolidated balance sheets in prepaid expenses and other and other assets, net, respectively. Current and noncurrent derivative liabilities are reported in our condensed consolidated balance sheets in accrued liabilities and retirement obligations and other liabilities, respectively.

The impact of net changes in the fair values of foreign exchange contracts are summarized below:

Gains and losses recognized in our condensed consolidated statements of income for foreign exchange contracts are classified as other expense, net.

In March 2015, we designated €255.7 million of our €500.0 million Euro senior notes discussed in Note 56 as a net investment hedge of our investments in certain of our international subsidiaries that use the Euro as their functional currency. We used the spot method to measure the effectiveness of our net investment hedge. Under this method, for each reporting period, the change in the carrying value of the Euro senior notes due to remeasurement of the effective portion is reported in accumulated other comprehensive loss on our condensed consolidated balance sheet and the remaining change in the carrying value of the ineffective portion, if any, is recognized in other expense, net in our condensed consolidated statement of income. We evaluate the effectiveness of our net investment hedge on a prospective basis at the beginning of each quarter. We did not record any ineffectiveness for the threesix months ended March 31,June 30, 2018 and 2017.

Debt, including capital lease obligations, consisted of:

As discussed in Note 10 to our consolidated financial statements included in our 2017 Annual Report, our credit agreement provides for an initial $400.0 million term loan (“Term Loan Facility”) and a $800.0 million revolving credit facility (“Revolving Credit Facility” and, together with the Term Loan Facility, the “Senior Credit Facility”) with a maturity date of October 14, 2020. As of March 31,June 30, 2018 and December 31, 2017, we had no amounts outstanding under the Revolving Credit Facility. We had outstanding letters of credit of $81.6$76.3 million and $94.8 million at March 31,June 30, 2018 and December 31, 2017, respectively, which reducedtogether with financial covenant limitations based on the terms of our Senior Credit Facility, contributed to the reduction of our borrowing capacity to $718.4$432.6 million and $644.8 million, respectively. Our compliance with applicable financial covenants under the Senior Credit Facility is tested quarterly, and we complied with all applicable covenants as of March 31,June 30, 2018.

We may prepay loans under our Senior Credit Facility in whole or in part, without premium or penalty, at any time. A commitment fee, which is payable quarterly on the daily unused portions of the Senior Credit Facility, was 0.20% (per annum) during the period ended March 31,June 30, 2018. During the threesix months ended March 31,June 30, 2018, we made scheduled repayments of $15.0$30.0 million under our Term Loan Facility. We have scheduled repayments of $15.0 million due in each of the next four quarters on our Term Loan Facility.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models may be applied. Assets and liabilities recorded at fair value in our condensed consolidated balance sheets are categorized by hierarchical levels based upon the level of judgment associated with the inputs used to measure their fair values. Recurring fair value measurements are limited to investments in derivative instruments. The fair value measurements of our derivative instruments are determined using models that maximize the use of the observable market inputs including interest rate curves and both forward and spot prices for currencies, and are classified as Level II under the fair value hierarchy. The fair values of our derivatives are included in Note 4.5.

Inventories, net consisted of the following:

As a result of our adoption of the New Revenue Standard as of January 1, 2018, progress billings and work in process amounts associated with contracts accounted under the over time method were either recognized as COS or reclassified into contract assets, net or contract liabilities. Refer to Note 2 of this Quarterly Report for a discussion on our adoption of the New Revenue Standard.

The following is a reconciliation of net earnings of Flowserve Corporation and weighted average shares for calculating net earnings per common share. Earnings per weighted average common share outstanding was calculated as follows:

We are a defendant in a substantial number of lawsuits that seek to recover damages for personal injury allegedly caused by exposure to asbestos-containing products manufactured and/or distributed by our heritage companies in the past. While the overall number of asbestos-related claims has generally declined in recent years, there can be no assurance that this trend will continue, or that the average cost per claim will not further increase. Asbestos-containing materials incorporated into any such products were encapsulated and used as internal components of process equipment, and we do not believe that any significant emission of asbestos fibers occurred during the use of this equipment.

We are currently involved as a potentially responsible party at five former public waste disposal sites in various stages of evaluation or remediation. The projected cost of remediation at these sites, as well as our alleged "fair share" allocation, will remain uncertain until all studies have been completed and the parties have either negotiated an amicable resolution or the matter has been judicially resolved. At each site, there are many other parties who have similarly been identified. Many of the other parties identified are financially strong and solvent companies that appear able to pay their share of the remediation costs. Based on our information about the waste disposal practices at these sites and the environmental regulatory process in general, we believe that it is likely that ultimate remediation liability costs for each site will be apportioned among all liable parties, including site owners and waste transporters, according to the volumes and/or toxicity of the wastes shown to have been disposed of at the sites. We believe that our financial exposure for existing disposal sites will not be materially in excess of accrued reserves.

As previously disclosed in our 2017 Annual Report, we terminated an employee of an overseas subsidiary after uncovering actions that violated our Code of Business Conduct and may have violated the Foreign Corrupt Practices Act.  We completed our internal investigation into the matter, self-reported the potential violation to the United States Department of Justice (the “DOJ”) and the SEC, and continue to cooperate with the DOJ and SEC.  We previously received a subpoena from the SEC requesting additional information and documentation related to the matter and have completed our response to the subpoena.  We currently believe that this matter will not have a material adverse financial impact on the Company, but there can be no assurance that the Company will not be subjected to monetary penalties and additional costs. 

We are also a defendant in a number of other lawsuits, including product liability claims, that are insured, subject to the applicable deductibles, arising in the ordinary course of business, and we are also involved in other uninsured routine litigation incidental to our business. We currently believe none of such litigation, either individually or in the aggregate, is material to our business, operations or overall financial condition. However, litigation is inherently unpredictable, and resolutions or dispositions of claims or lawsuits by settlement or otherwise could have an adverse impact on our financial position, results of operations or cash flows for the reporting period in which any such resolution or disposition occurs.

Although none of the aforementioned potential liabilities can be quantified with absolute certainty except as otherwise indicated above, we have established reserves covering exposures relating to contingencies, to the extent believed to be reasonably estimable and probable based on past experience and available facts. While additional exposures beyond these reserves could exist, they currently cannot be estimated. We will continue to evaluate and update the reserves as necessary and appropriate.
