NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Background and Basis of Presentation

Background

Xylem Inc. ("Xylem" or the "Company") is a leading equipment and service provider for water and wastewater applications with a broad portfolio of products and services addressing the full cycle of water, from collection, distribution and use to the return of water to the environment. Xylem was incorporated in Indiana on May 4, 2011.

As previously announced, in the second quarter of 2017 we implemented an organizational redesign by moving Xylem’s Analytics business from our Water Infrastructure business to combining it with our Sensus business, which was acquired in the fourth quarter of 2016, to form Measurement & Control Solutions (formerly Sensus & Analytics). We believe that the combination of these businesses will enhance our focus on advanced sensing technologies and will lead to operating efficiencies by integrating the supply chain process and moving to a leaner functional structure.  Accordingly, our reportable segments have changed. Beginning with the second quarter of 2017, the Company now reports the financial position and results of operations of its Analytics and Sensus businesses as one new reportable segment, which is currently called Measurement & Control Solutions. Our Water Infrastructure reportable segment no longer includes the results of our Analytics business. The Company has recast certain historical amounts between the Company's Water Infrastructure and Measurement & Control Solutions reportable segments, however this change had no impact on the Company's historical consolidated financial position or results of operations. The recast financial information does not represent a restatement of previously issued financial statements. Our Applied Water reportable segment remains unchanged. Refer to Note 18 "Segment Information" for additional segment information.

Xylem operates in three segments, Water Infrastructure, Applied Water and Measurement & Control Solutions. The Water Infrastructure segment focuses on the transportation and treatment of water, offering a range of products including water and wastewater pumps, treatment equipment, and controls and systems. The Applied Water segment serves many of the primary uses of water and focuses on the residential, commercial and industrial markets. The Applied Water segment’s major products include pumps, valves, heat exchangers, controls and dispensing equipment. The Measurement & Control Solutions segment focuses on developing advanced technology solutions that enable intelligent use and conservation of critical water and energy resources as well as analytical instrumentation used in the testing of water. The Measurement & Control Solutions segment's major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and testing equipment.

Except as otherwise indicated or unless the context otherwise requires, "Xylem," "we," "us," "our" and the "Company" refer to Xylem Inc. and its subsidiaries.

Basis of Presentation

The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated.

The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair presentation of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2016 ("2016 Annual Report") in preparing these unaudited condensed consolidated financial statements, with the exception of accounting standard updates described in Note 2. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2016 Annual Report.

7

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, postretirement obligations and assets, revenue recognition, income tax contingency accruals and valuation allowances, goodwill and indefinite lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates.

Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.

Note 2. Recently Issued Accounting Pronouncements

Pronouncements Not Yet Adopted

In August 2017, the Financial Accounting Standards Board (“FASB”) issued amended guidance on hedging activities. The amendment better aligns a company’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying for hedging relationships and the presentation of hedge results. Specifically, the guidance:

(1)Eliminates the concept of recognizing periodic hedge ineffectiveness for cash flow and net investment hedges

(2)Eliminates the benchmark interest rate concept of variable - rate instruments in cash flow hedges and allows companies to designate the contractually specified interest rate as the hedged risk

(3)Requires a company to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported

(4)Provides the ability to perform subsequent hedge effectiveness tests qualitatively

This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted with the effect of adoption reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing at the date of adoption, a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness is required. Other presentation and disclosure guidance is required only prospectively. We are evaluating the impact of the guidance on our financial condition and results of operations.

In March 2017, the FASB issued amended guidance on presentation of net periodic benefit costs.  The amendment requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period.  The other components are required to be presented in the income statement separately and outside a subtotal of income from operations, if one is presented.  The amendment also requires entities to disclose the income statement lines that contain the other components if they are not appropriately described.  This guidance is effective retrospectively for periods beginning after December 15, 2017, including interim periods within those annual periods.  Early adoption is permitted.  The adoption of this guidance is expected to impact the presentation between operating income and other non operating income within Xylem's Consolidated Income Statement but is not expected to have a material impact on our consolidated financial condition or results of operations.

In June 2016, the FASB issued guidance amending the accounting for the impairment of financial instruments, including trade receivables. Under current guidance, credit losses are recognized when the applicable losses are probable of occurring and this assessment is based on past events and current conditions. The amended guidance eliminates the “probable” threshold and requires an entity to use a broader range of information, including forecast information when estimating expected credit losses. Generally, this should result in a more timely recognition of credit losses. This guidance is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted for interim and annual periods beginning after December 15, 2018. The requirements of the amended guidance should be applied using a modified retrospective approach except for debt securities, which require a prospective transition approach. We are evaluating the impact of the guidance on our financial condition and results of operations.

8

In February 2016, the FASB issued guidance amending the accounting for leases. Specifically, the amended guidance requires all lessees to record a lease liability at lease inception, with a corresponding right of use asset, except for short-term leases. Lessor accounting is not fundamentally changed. This amended guidance is effective for interim and annual periods beginning after December 15, 2018 using a modified retrospective approach. Early adoption is permitted. We are evaluating the impact of the guidance on our financial condition and results of operations.

In May 2014, the FASB issued guidance on recognizing revenue from contracts with customers. The guidance outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the model is that an entity recognizes revenue to portray the transfer of goods and 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. The standard also expands disclosure requirements regarding revenue recognition. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017 and may be applied retrospectively to each prior period presented or using a modified retrospective approach with the cumulative effect recognized as of the date of initial application. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2016. The impact of this guidance on our financial condition and results of operations will be based on the types of contracts that Xylem is awarded in the future. We currently do not believe that the adoption of this guidance will have a material impact on our financial statements and plan to adopt this guidance effective January 1, 2018 using the modified retrospective approach.

Recently Adopted Pronouncements

In May 2017, the FASB issued guidance, which amends the scope of modification accounting guidance for share-based payment arrangements. The guidance outlines the types of changes to the terms or conditions of share-based payment arrangements that would require the use of modification accounting. Specifically, modification accounting would not apply if the fair value, vesting conditions, and classification of the award as equity or liability are the same immediately before and after the modification. This guidance is effective prospectively for interim and annual reporting periods beginning December 15, 2017 and early adoption is permitted. We elected to early adopt this guidance effective the second quarter of 2017. The adoption of this guidance did not impact our financial condition or results from operations.

In January 2017, the FASB issued guidance amending the impairment testing of goodwill. Under current guidance, the testing of goodwill for impairment is performed at least annually using a two-step test. Step one involves comparing the fair value of a “reporting unit” to its carrying amount. If the applicable book value exceeds the reporting unit’s fair value then step two must be performed. Step two involves comparing the fair value of the reporting unit’s goodwill to the applicable carrying amount of the asset and recognizing an impairment charge equal to the amount by which the carrying amount of the goodwill exceeds its implied fair value. The amended guidance eliminates step two of the impairment test and allows an entity to record an impairment charge equal to the amount that the carrying amount of the applicable reporting unit exceeds its fair value, up to the value of the recorded goodwill. This guidance is effective prospectively for interim and annual goodwill impairment tests beginning after December 15, 2019 with early adoption permitted for interim or annual tests after January 1, 2017. We elected to early adopt this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

In October 2016, the FASB issued guidance amending the accounting for income taxes. Under current guidance the recognition of current and deferred income taxes for an intra-entity asset transfer is prohibited until the asset has been sold to an outside party. The amended guidance eliminates the prohibition against immediate recognition of current and deferred income tax amounts associated with intra-entity transfers of assets other than inventory. This guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. The requirements of the amended guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We elected to early adopt this guidance effective the first quarter of 2017. As a result of adopting the amended guidance, prepaid tax assets were reduced by $14 million, long-term deferred tax assets increased $3 million, and accrued taxes were reduced by $4 million. The net impact of these adjustments on retained earnings was a decrease of $7 million.

In July 2015, the FASB issued guidance regarding simplifying the measurement of inventory. Under prior guidance, inventory is measured at the lower of cost or market, where market is defined as replacement cost, with

9

a ceiling of net realizable value and a floor of net realizable value less a normal profit margin. The amended guidance requires the measurement of inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective prospectively for interim and annual periods beginning after December 15, 2016 and early application is permitted. We adopted this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

Note 3. Acquisitions and Divestitures

2017 Acquisitions and Divestitures

Acquisitions

During the three and nine months ended September 30, 2017 we spent approximately $10 million and $16 million, respectively, on various acquisition activity.

Divestitures

On February 17, 2017, we divested our United Kingdom and Poland based membranes business for approximately $10 million. The sale resulted in a gain of $4 million, which is reflected in gain from sale of business in our Condensed Consolidated Income Statement. The business, which was part of our Applied Water segment, provided membrane filtration products primarily to customers in the municipal water and industrial sectors. The business reported 2016 annual revenue of approximately $8 million.

2016 Acquisitions and Divestitures

Sensus Worldwide Limited

On October 31, 2016, the Company acquired all of the outstanding equity interests of Sensus Worldwide Limited (other than Sensus Industries Limited) (“Sensus”) effective October 31, 2016 for $1,766 million ($1,710 million net of cash acquired), including a $6 million payment in 2017 for a working capital adjustment. Sensus develops advanced technology solutions that enable intelligent use and conservation of critical water and energy resources. Sensus' major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management.

Sensus results of operations were consolidated with the Company effective November 1, 2016 and along with our Analytics business it constitutes a separate reportable segment. Refer to Note 18 "Segment Information" for Measurement & Control Solutions segment information.

10

The Sensus purchase price allocation as of October 31, 2016 is shown in the following table.

(in millions)	Amount
Cash	$	56
Receivables	104
Inventories	79
Prepaid and other current assets	19
Property, plant and equipment	176
Intangible assets	782
Other long-term assets	5
Accounts payable	(69		)
Accrued and other current liabilities	(90		)
Deferred income tax liabilities	(198		)
Accrued post retirement benefits	(84		)
Other non-current accrued liabilities	(60		)
Total identifiable net assets	720
Goodwill	1,063
Non-controlling interest	(17		)
Total consideration	$	1,766

In the third quarter of 2017 we finalized the Sensus purchase price allocation. The fair values of Sensus assets and liabilities were determined based on estimates and assumptions which management believes are reasonable.

Goodwill arising from the acquisition consists largely of synergies and economies of scale expected from combining the operations of Sensus and Xylem. All of the goodwill was assigned to the Measurement & Control Solutions segment and is not deductible for tax purposes.

The estimate of the fair value of Sensus identifiable intangible assets was determined primarily using the “income approach,” which requires a forecast of all of the expected future cash flows either through the use of the multi-period excess earnings method or the relief-from-royalty method. Some of the more significant assumptions inherent in the development of intangible asset values include: the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows, the assessment of the intangible asset’s life cycle, as well as other factors. The following table summarizes key information underlying identifiable intangible assets related to the Sensus acquisition:

Category	Life	Amount (in millions)
Customer and Distributor Relationships	2 - 18 years	$	543
Tradenames	10 - 25 years	98
Internally Developed Network Software	7 years	60
FCC Licenses	Indefinite lived	24
Technology	5 - 15 years	39
Other	1 - 16 years	18
Total		$	782

The following table summarizes, on an unaudited pro forma basis, the condensed combined results of operations of the Company for the three and nine months ended September 30, 2016 assuming the acquisition of Sensus was made on January 1, 2015.

11

(in millions)	Three Months Ended September 30, 2016		Nine Months Ended September 30, 2016
Revenue	$	1,123	$	3,365
Net income	$	80	$	263

The foregoing unaudited pro forma results are for informational purposes only and are not necessarily indicative of the actual results of operations that might have occurred had the acquisition occurred on January 1, 2015, nor are they necessarily indicative of future results. The pro forma financial information includes the impact of purchase accounting and other nonrecurring items directly attributable to the acquisition, which include:

• Amortization expense of acquired intangibles

• Adjustments to the depreciation of property, plant and equipment reflecting the impact of the calculated fair value of those assets in accordance with purchase accounting

• Amortization of the fair value adjustment for warranty liabilities

• Adjustments to interest expense to remove historical Sensus interest costs and reflect Xylem's current debt profile

• The related tax impact of the above referenced adjustments

The pro forma results do not include any cost savings or operational synergies that may be generated or realized due to the acquisition of Sensus. The pro forma nine-month period reflects the inclusion of a $16 million tax valuation release and a $27 million reduction to warranty expense in the first calendar quarter of 2016.

Tideland Signal Corporation

On February 1, 2016, we acquired Tideland Signal Corporation (“Tideland”), a leading producer of analytics solutions in the coastal and ocean management sectors, for $70 million. Tideland, a privately-owned company headquartered in Texas, had approximately 160 employees. Our condensed consolidated financial statements include Tideland’s results of operations from February 1, 2016 within the Measurement & Control Solutions segment.

Note 4. Restructuring Charges

From time to time, the Company will incur costs related to restructuring actions in order to optimize our cost base and more strategically position ourselves based on the economic environment and customer demand. During the three and nine months ended September 30,2017, we recognized restructuring charges of $4 million and $17 million, respectively. We incurred these charges primarily as a continuation of our efforts to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water and Water Infrastructure segments, as well as headcount reductions within our Measurement & Control Solutions segment.

During the three and nine months ended September 30,2016, we recognized restructuring charges of $6 million and $18 million, respectively. We incurred these charges primarily in an effort to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water and Water Infrastructure segments, as well as Corporate headcount reductions.

The Water Infrastructure, Applied Water, Measurement & Control Solutions and Corporate actions commenced in 2016 consist primarily of severance charges and are expected to continue through the end of 2018.

Asset Impairment Charges

During the first quarter of 2017 we determined that certain assets within our Applied Water segment, including a tradename, were impaired. Accordingly we recognized an impairment charge of $5 million. Refer to Note 9, "Goodwill and Other Intangible Assets," for additional information.

Note 5. Income Taxes

Our quarterly provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items within periods presented. The comparison of our effective tax rate between periods is significantly impacted by the level and mix of earnings and losses by tax jurisdiction, foreign income tax rate differentials and discrete items.

The income tax provision for the three months ended September 30, 2017 was $27 million resulting in an effective tax rate of 21.1%, compared to $22 million resulting in an effective tax rate of 22.9% for the same period in 2016. The income tax provision for the nine months ended September 30, 2017 was $62 million resulting in an effective tax rate of 19.4%, compared to $40 million resulting in an effective tax rate of 16.0% for the same period in 2016. The effective tax rate was lower than the United States federal statutory rate primarily due to the mix of earnings in jurisdictions in both periods. Additionally, the effective tax rate for the nine months ended September 30, 2016

14

was lower than the current period due to the release of an unrecognized tax benefit in 2016 due to the effective settlement of a tax examination, partially offset by the nonrecurring repatriation of foreign earnings from 2016.

Unrecognized Tax Benefits

We recognize tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the condensed consolidated financial statements from such positions are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

The amount of unrecognized tax benefits at September 30, 2017 was $75 million, as compared to $67 million at December 31, 2016, which if ultimately recognized will reduce our effective tax rate. We do not believe that the unrecognized tax benefits will significantly change within the next twelve months.

We classify interest expense relating to unrecognized tax benefits as a component of other non-operating expense, net, and tax penalties as a component of income tax expense in our Condensed Consolidated Income Statements. As of September 30, 2017, we had $3.6 million of interest accrued for unrecognized tax benefits.

Note 6. Earnings Per Share

The following is a reconciliation of the shares used in calculating basic and diluted net earnings per share.

	Three Months Ended				Nine Months Ended
	September 30,				September 30,

Diluted earnings per share	$	0.58	$	0.41	$	1.44	$	1.17

(a) Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

(b) Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 14, "Share-Based Compensation Plans" to the condensed consolidated financial statements for further detail on the performance share units.

	Three Months Ended		Nine Months Ended

During the first quarter of 2017 we determined that the intended use of a finite lived trade name within our Applied Water segment had changed. Accordingly we recorded a $4 million impairment charge. The charge was calculated using income approach, which is considered a Level 3 input for fair value measurement, and is reflected in “Restructuring and asset impairment charges” in our Condensed Consolidated Income Statements.

Note 10. Derivative Financial Instruments

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions, and principally manage our exposures to these risks through management of our core business activities. Certain of our foreign operations expose us to fluctuations of foreign interest rates and exchange rates that may impact revenue, expenses, cash receipts, cash payments, and the value of our stockholders' equity. We enter into derivative financial instruments to protect the value or fix the amount of certain cash flows in terms of the functional currency of the business unit with that exposure and reduce the volatility in stockholders' equity.

Cash Flow Hedges of Foreign Exchange Risk

We are exposed to fluctuations in various foreign currencies against our functional currencies. We use foreign currency derivatives, including currency forward agreements, to manage our exposure to fluctuations in the various exchange rates. Currency forward agreements involve fixing the foreign currency exchange rate for delivery of a specified amount of foreign currency on a specified date.

17

Certain business units with exposure to foreign currency exchange risks have designated certain currency forward agreements as cash flow hedges of forecasted intercompany inventory purchases and sales. Our principal currency exposures relate to the Euro, Swedish Krona, British Pound, Canadian Dollar, Polish Zloty Australian Dollar and Hungarian Forint. We had foreign exchange contracts with purchase notional amounts totaling $58 million as of September 30, 2017. As of September 30, 2017, our most significant foreign currency derivatives included contracts to purchase Swedish Krona and sell Euro, sell U.S. Dollar and purchase Euro, sell British Pound and purchase Euro, and to purchase Polish Zloty and sell Euro. The purchased notional amounts associated with these currency derivatives are $26 million, $9 million, $8 million, and $7 million, respectively. As of December 31, 2016 we did not hold any foreign exchange contracts.

Hedges of Net Investments in Foreign Operations

We are exposed to changes in foreign currencies impacting our net investments held in foreign subsidiaries.

Cross Currency Swaps

Beginning in 2015, we entered into cross currency swaps to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. The total notional amount of derivative instruments designated as net investment hedges was $440 million and $391 million as of September 30, 2017 and December 31, 2016, respectively.

Foreign Currency Denominated Debt

On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023. We designated the entirety of the outstanding balance, or $583 million, net of unamortized discount, as a hedge of a net investment in certain foreign subsidiaries.

The table below presents the effect of our derivative financial instruments on the Condensed Consolidated Income Statements and Statements of Comprehensive Income.

	Three Months Ended						Nine Months Ended

(a) Effective portion

As of September 30, 2017, $3 million of net gains on cash flow hedges are expected to be reclassified into earnings in the next 12 months. The ineffective portion of a cash flow hedge is recognized immediately in selling, general and administrative expenses in the Condensed Consolidated Income Statements and was not material for the three and nine months ended September 30,2017 and 2016.

As of September 30, 2017, no gains or losses on the net investment hedges are expected to be reclassified into earnings over their duration. The net investment hedges did not experience any ineffectiveness for the three and nine months ended September 30,2017.

The fair values of our derivative assets and liabilities are measured on a recurring basis using Level 2 inputs and are determined through the use of models th at consider various assumptions including yield curves, time value and other measurements.

18

The fair values of our foreign exchange contracts currently included in our hedging program designated as hedging instruments were as follows:

(a) The fair value of our Senior Notes was determined using quoted prices in active markets for identical securities, which are considered Level 1 inputs. The fair value of our Senior Notes due 2021 was $653 million and $651 million as of September 30, 2017 and December 31, 2016, respectively. The fair value of our Senior Notes due 2023 was $630 million and $555 million as of September 30, 2017 and December 31, 2016, respectively. The fair value of our Senior Notes due 2026 was $499 million and $487 million as of September 30, 2017 and December 31, 2016, respectively.The fair value of

19

our Senior Notes due 2046 was $419 million and $397 million as of September 30, 2017 and December 31, 2016, respectively.

(b) The debt issuance costs and unamortized discount are recognized as a reduction in the carrying value of the Senior Notes in the Condensed Consolidated Balance Sheets and are being amortized to interest expense in our Condensed Consolidated Income Statements over the expected remaining terms of the Senior Notes.

Senior Notes

On September 20, 2011, we issued 3.550% Senior Notes of $600 million aggregate principal amount due September 2016 (the "Senior Notes due 2016") and 4.875% Senior Notes of $600 million aggregate principal amount due October 2021 (the "Senior Notes due 2021"). On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023 (the "Senior Notes due 2023"). On October 11, 2016, we issued 3.250% Senior Notes of $500 million aggregate principal amount due October 2026 (the “Senior Notes due 2026”) and 4.375% Senior Notes of $400 million aggregate principal amount due October 2046 (the “Senior Notes due 2046” and, together with the Senior Notes due 2021, the Senior Notes due 2023 and the Senior Notes due 2026, the “Senior Notes”).

The Senior Notes include covenants that restrict our ability, subject to exceptions, to incur debt secured by liens and engage in sale and leaseback transactions, as well as provide for customary events of default (subject, in certain cases, to receipt of notice of default and/or customary grace and cure periods). We may redeem the Senior Notes, as applicable, in whole or in part, at any time at a redemption price equal to the principal amount of the Senior Notes to be redeemed, plus a make-whole premium. We may also redeem the Senior Notes in certain other circumstances, as set forth in the applicable Senior Notes indenture.

If a change of control triggering event (as defined in the applicable Senior Notes indenture) occurs, we will be required to make an offer to purchase the Senior Notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to the date of repurchase.

Interest on the Senior Notes due 2021 is payable on April 1 and October 1 of each year. Interest on the Senior Notes due 2023 is payable on March 11 of each year. Interest on the Senior Notes due 2026 and the Senior Notes due 2046 is payable on May 1 and November 1 of each year beginning on May 1, 2017. As of September 30, 2017, we were in compliance with all covenants for the Senior Notes.

We used the net proceeds of the Senior Notes due 2026 and the Senior Notes due 2046, together with cash on hand, proceeds from issuances under our existing commercial paper program and borrowings under the Term Facility (as described below), to fund the acquisition of Sensus (refer to Note 3 for further information on the Sensus acquisition).

Credit Facilities

Five-Year Revolving Credit Facility

Effective March 27, 2015, Xylem entered into a Five-Year Revolving Credit Facility (the "Credit Facility") with Citibank, N.A., as administrative agent, and a syndicate of lenders. The Credit Facility provides for an aggregate principal amount of up to $600 million of: (i) revolving extensions of credit (the "revolving loans") outstanding at any time and (ii) the issuance of letters of credit in a face amount not in excess of $100 million outstanding at any time. The Credit Facility provides for increases of up to $200 million for a possible maximum total of $800 million in aggregate principal amount at our request and with the consent of the institutions providing such increased commitments.

At our election, the interest rate per annum applicable to the revolving loans will be based on either (i) a Eurodollar rate determined by reference to LIBOR, adjusted for statutory reserve requirements, plus an applicable margin or (ii) a fluctuating rate of interest determined by reference to the greatest of: (a) the prime rate of Citibank, N.A., (b) the U.S. Federal funds effective rate plus half of 1% or (c) the Eurodollar rate determined by reference to LIBOR, adjusted for statutory reserve requirements, in each case, plus an applicable margin.

20

In accordance with the terms of an amendment to the Credit Facility dated August 30, 2016, we may not exceed a maximum leverage ratio of 4.00 to 1.00 (based on a ratio of total debt to earnings before interest, taxes, depreciation and amortization) for a period of four full fiscal quarters following the Sensus acquisition and a maximum leverage ratio of 3.50 to 1.00 through the rest of the term. The Credit Facility also contains limitations on, among other things, incurring secured debt, granting liens, entering into sale and leaseback transactions, mergers, consolidations, liquidations, dissolutions and sales of assets. In addition, the Credit Facility contains other terms and conditions such as customary representations and warranties, additional covenants and customary events of default. As of September 30, 2017 the Credit Facility was undrawn and we are in compliance with all covenants.

European Investment Bank - R&D Finance Contract

On October 28, 2016, the Company entered into a Finance Contract (the “Finance Contract”) with the European Investment Bank (the “EIB”). The Company's wholly owned subsidiaries in Luxembourg, Xylem Holdings S.á r.l. and Xylem International S.á r.l., are the borrowers under the Finance Contract and Xylem Inc. is the Guarantor.  The Finance Contract provides for up to €105 million (approximately $124 million) to finance research, development and innovation projects in the field of sustainable water and wastewater solutions during the period from 2017 through 2019 in Sweden, Germany, Italy, UK, Hungary and Austria. The Company has unconditionally guaranteed the performance of the borrowers under the Finance Contract.Under the Finance Contract, the borrowers are able to draw loans on or before April 28, 2018, with a maturity of no longer than 11 years.

Both the Finance Contract and the R&D Facility Agreement (described below) are subject to the same leverage ratio as the Credit Facility. Both agreements also contain limitations on, among other things, incurring debt, granting liens, and entering into sale and leaseback transactions, as well as other terms and conditions, such as customary representations and warranties, additional covenants and customary events of default.

Both the Finance Contract and the R&D Facility Agreement provide for fixed rate loans and floating rate loans. Under the Finance Contract, the interest rate per annum applicable to fixed rate loans is at a fixed percentage rate per annum specified by the EIB which includes the applicable margin. The interest rate per annum applicable to floating rate loans is at the rate determined by reference to EURIBOR for loans drawn in Euros and LIBOR for loans drawn in Pounds Sterling or U.S. Dollars, plus an applicable spread specified by the EIB which includes the applicable margin. The applicable margin is 59 basis points (0.59%). As of September 30, 2017 and December 31, 2016, $124 million and $110 million were outstanding under the Finance Contract, respectively.

European Investment Bank - R&D Facility Agreement

On December 3, 2015, the Company amended and restated its Risk Sharing Finance Facility Agreement (the "R&D Facility Agreement") with the EIB to amend the maturity date. The Facility provides an aggregate principal amount of up to €120 million (approximately $141 million) to finance research projects and infrastructure development in the European Union. The Company's wholly owned subsidiaries in Luxembourg, Xylem Holdings S.á r.l. and Xylem International S.á r.l., are the borrowers under the R&D Facility Agreement. The obligations of the borrowers under the R&D Facility Agreement are guaranteed by the Company under an Amended and Restated Deed of Guarantee, dated as of December 4, 2013, in favor of the EIB.

Under the R&D Facility Agreement, the borrower was able to draw loans on or before March 31, 2016 with a maturity of no longer than 12 years. As of September 30, 2017 and December 31, 2016 $43 million and $38 million were outstanding, respectively, under the R&D Facility Agreement. Although the borrowing term for this arrangement is up to five years, we have classified it as short-term debt on our Consolidated Balance Sheets since we intend to repay this obligation in less than a year.

Term Loan Facility

On October 24, 2016, the Company’s subsidiary, Xylem Europe GmbH (the “borrower”) entered into a 12-month €150 million (approximately $177 million) term loan facility (the “Term Facility”) the terms of which are set forth in a term loan agreement, among the borrower, the Company, as parent guarantor and ING Bank.  The Company has entered into a parent guarantee in favor of ING Bank also dated October 24, 2016 to secure all present and future obligations of the borrower under the Term Loan Agreement.  The Term Facility was used to partially fund the acquisition of Sensus. The Term Facility will mature on October 26, 2017. The Term Facility bears interest at EURIBOR plus 0.35%. The agreement contains certain representations and warranties, certain affirmative covenants, certain negative covenants, a financial covenant, certain conditions and events of default that are customarily required for similar financings. As of September 30, 2017 and December 31, 2016, $24 million and

21

$157 million were outstanding under the Term Loan Facility, respectively. The remaining outstanding balance was paid off in October 2017.

Commercial Paper

Our commercial paper program generally serves as a means of short-term funding and has a combined outstanding limit of $600 million inclusive of the Five-Year Revolving Credit Facility. As of September 30, 2017 and December 31, 2016 $30 million and $65 million of the Company’s $600 million commercial paper program was outstanding at a weighted average interest rate of 1.44% and 1.12%, respectively. We will periodically borrow under this program and may borrow under it in future periods.

The total net periodic benefit cost for other postretirement employee benefit plans was $1 million and $2 million including amounts recognized in other comprehensive income ("OCI") of less than $1 million, for both the three and nine months ended September 30,2017. The total net periodic benefit cost for other postretirement employee benefit plans was $1 million and $2 million, including amounts recognized in OCI of less than $1 million, for both the three and nine months ended September 30,2016.

We contributed $28 million and $22 million to our defined benefit plans during the nine months ended September 30, 2017 and 2016, respectively. A discretionary $6 million contribution was made to the U.S. plan in Q3 2017 to increase the funding ratio and reduce regulatory fees. Additional contributions ranging between approximately $3 million and $9 million are expected during the remainder of 2017.

Note 14. Share-Based Compensation Plans

Share-based compensation expense was $5 million and $16 million during the three and nine months ended September 30, 2017, respectively, and $5 million and $15 million during the three and nine months ended September 30,2016, respectively. The unrecognized compensation expense related to our stock options, restricted stock units and performance share units was $7 million, $21 million and $14 million, respectively, at September 30, 2017 and is expected to be recognized over a weighted average period of 1.9, 2.0 and 2.0 years, respectively. The amount of cash received from the exercise of stock options was $8 million and $22 million for the nine months endedSeptember 30, 2017 and 2016, respectively.

Stock Option Grants

The following is a summary of the changes in outstanding stock options for the nine months ended September 30, 2017.

	Share units            (in thousands)		Weighted Average Exercise Price / Share		Weighted  Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2017	2,126		$	33.71	6.9
Granted	501		48.43
Exercised	(257	)	31.87
Forfeited and expired	(50	)	42.08
Outstanding at September 30, 2017	2,320		$	36.91	7.0	$	60
Options exercisable at September 30, 2017	1,383		$	32.89	5.8	$	41
Vested and expected to vest as of September 30, 2017	2,219		$	35.87	6.8	$	58

The total intrinsic value of options exercised (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) during the nine months ended September 30, 2017 was $5.5 million.

Stock Option Fair Value

The fair value of each option grant was estimated on the date of grant using the binomial lattice pricing model which incorporates multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The following are weighted-average assumptions for 2017 grants.

Volatility	25.40		%
Risk-free interest rate	2.07		%
Dividend yield	1.49		%
Expected term (in years)	5.1
Weighted-average fair value / share	$	10.66

Expected volatility is calculated based on a weighted analysis of historic and implied volatility measures for a set of peer companies and Xylem. We use historical data to estimate option exercise and employee termination behavior within the valuation model. Employee groups and option characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time options are expected to remain outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of option grant.

Restricted Stock Unit Grants

The following is a summary of restricted stock unit activity for the nine months ended September 30, 2017. The fair value of the restricted stock units is equal to the closing share price on the date of the grant. 

	Share units (in thousands)		Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2017	899		$	37.67
Granted	344		49.69
Vested	(357	)	38.24
Forfeited	(60	)	40.78
Outstanding at September 30, 2017	826		$	35.53

23

ROIC Performance Share Unit Grants

The following is a summary of Return on Invested Capital ("ROIC") performance share unit grants for the nine months ended September 30, 2017. The fair value of the ROIC performance share units is equal to the closing share price on the date of the grant. 

	Share units (in thousands)		Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2017	250		$	37.11
Granted	117		49.15
Vested	—		—
Forfeited	(68	)	38.44
Outstanding at September 30, 2017	299		$	41.50

TSR Performance Share Units Grants

The following is a summary of our Total Shareholder Return ("TSR") performance share unit grants for the nine months ended September 30, 2017.

	Share units (in thousands)		Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2017	108		$	46.15
Granted	117		47.79
Vested	—		—
Forfeited	(11	)	43.98
Outstanding at September 30, 2017	214		$	47.03

The fair value of TSR performance share units was calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The following are weighted-average assumptions for 2017 grants.

Volatility	30.2	%
Risk-free interest rate	1.50	%

Note 15. Capital Stock

For the three and nine months ended September 30, 2017 the Company repurchased less than 0.1 million shares for less than $1 million and 0.5 million shares for $25 million of common stock, respectively. Repurchases include both share repurchase programs approved by the Board of Directors and repurchases in relation to settlement of employee tax withholding obligations due as a result of the vesting of restricted stock units. The detail of repurchases by each program are as follows:

On August 24, 2015, our Board of Directors authorized the repurchase of up to $500 million in shares with no expiration date. The program's objective is to deploy our capital in a manner that benefits our shareholders and maintains our focus on growth. There were no shares repurchased under this program for the three months ended September 30, 2017. For the nine months ended September 30, 2017 we repurchased 0.1 million shares for $7 million. There were no shares repurchased under this program during the three and nine months ended September 30,2016. There are up to $413 million in shares that may still be purchased under this plan as of September 30, 2017.

24

On August 18, 2012, our Board of Directors authorized the repurchase of up to 2.0 million shares of common stock with no expiration date. The program's objective is to offset dilution associated with various Xylem employee stock plans by acquiring shares in the open market from time to time. There were no shares repurchased under this program for the three months ended September 30, 2017. For the nine months ended September 30, 2017 we repurchased 0.25 million shares for $13 million. There were no shares repurchased under this program during the three and nine months ended September 30,2016. As of June 30, 2017, we have exhausted the authorized amount to repurchase shares under this plan.

Aside from the aforementioned repurchase programs, we repurchased less than 0.1 million shares and 0.1 million shares for less than $1 million and $5 million for the three and nine months ended September 30,2017, respectively, in relation to settlement of employee tax withholding obligations due as a result of the vesting of restricted stock units. Likewise, we repurchased less than 0.1 million shares and 0.1 million shares for less than $1 million and $3 million for the three and nine months ended September 30,2016, respectively.

Note 17. Commitments and Contingencies

Legal Proceedings

From time to time, we are involved in legal proceedings that are incidental to the operation of our businesses, including acquisitions and divestitures, intellectual property matters, product liability and personal injury claims, employment and pension matters, government and commercial contract disputes.

26

From time to time claims may be asserted against Xylem alleging injury caused by any of our products resulting from asbestos exposure. We believe there are numerous legal defenses available for such claims and would defend ourselves vigorously. Pursuant to the Distribution Agreement among ITT Corporation (now ITT LLC), Exelis and Xylem, ITT Corporation (now ITT LLC) has an obligation to indemnify, defend and hold Xylem harmless for asbestos product liability matters, including settlements, judgments, and legal defense costs associated with all pending and future claims that may arise from past sales of ITT’s legacy products. We believe ITT Corporation (now ITT LLC) remains a substantial entity with sufficient financial resources to honor its obligations to us.

Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claims, we do not expect that any asserted or unasserted legal claims or proceedings, individually or in aggregate, will have a material adverse effect on our results of operations, or financial condition. We have estimated and accrued $10 million and $11 million as of September 30, 2017 and December 31, 2016, respectively, for these general litigation matters.

Indemnifications

As part of our 2011 spin-off from our former parent, ITT Corporation (now ITT LLC), Exelis Inc. and Xylem will indemnify, defend and hold harmless each of the other parties with respect to such parties’ assumed or retained liabilities under the Distribution Agreement and breaches of the Distribution Agreement or related spin agreements. The former parent’s indemnification obligations include asserted and unasserted asbestos and silica liability claims that relate to the presence or alleged presence of asbestos or silica in products manufactured, repaired or sold prior to October 31, 2011, the Distribution Date, subject to limited exceptions with respect to certain employee claims, or in the structure or material of any building or facility, subject to exceptions with respect to employee claims relating to Xylem buildings or facilities. The indemnification associated with pending and future asbestos claims does not expire. Xylem has not recorded a liability for material matters for which we expect to be indemnified by the former parent or Exelis Inc. through the Distribution Agreement and we are not aware of any claims or other circumstances that would give rise to material payments from us under such indemnifications. On May 29, 2015, Harris Inc. acquired Exelis.  As the parent of Exelis, Harris Inc. is responsible for Exelis’s indemnification obligations under the Distribution Agreement.

Guarantees

We obtain certain stand-by letters of credit, bank guarantees and surety bonds from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance related requirements. As of September 30, 2017 and December 31, 2016, the amount of stand-by letters of credit, bank guarantees and surety bonds was $235 million and $218 million, respectively.

Environmental

In the ordinary course of business, we are subject to federal, state, local, and foreign environmental laws and regulations. We are responsible, or are alleged to be responsible, for ongoing environmental investigation and remediation of sites in various countries. These sites are in various stages of investigation and/or remediation and in many of these proceedings our liability is considered de minimis. We have received notification from the U.S. Environmental Protection Agency, and from similar state and foreign environmental agencies, that a number of sites formerly or currently owned and/or operated by Xylem or for which we are responsible under the Distribution Agreement, and other properties or water supplies that may be or have been impacted from those operations, contain disposed or recycled materials or wastes and require environmental investigation and/or remediation. These sites include instances where we have been identified as a potentially responsible party under federal and state environmental laws and regulations.

Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Our accrued liabilities for these environmental matters represent the best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees. These estimates, and related accruals, are reviewed quarterly and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. Liabilities for these environmental expenditures are recorded on an undiscounted basis. We have estimated and accrued $4 million and $4 million as of September 30, 2017 and December 31, 2016, respectively, for environmental matters.

27

It is difficult to estimate the final costs of investigation and remediation due to various factors, including incomplete information regarding particular sites and other potentially responsible parties, uncertainty regarding the extent of investigation or remediation and our share, if any, of liability for such conditions, the selection of alternative remedial approaches, and changes in environmental standards and regulatory requirements. We believe the total amount accrued is reasonable based on existing facts and circumstances.

Warranties

We warrant numerous products, the terms of which vary widely. In general, we warrant products against defect and specific non-performance. The table below provides the changes in our product warranty accrual, which for 2017 includes warranty related to the Sensus acquisition.

(in millions)	2017			2016
Warranty accrual – January 1	$	99		$	33
Net charges for product warranties in the period	25			20
Settlement of warranty claims	(36		)	(21		)
Foreign currency and other	3			3
Warranty accrual - September 30	$	91		$	35

Note 18. Segment Information

Our business has three reportable segments: Water Infrastructure, Applied Water and Measurement & Control Solutions. When determining the reportable segments, the Company aggregated operating segments based on their similar economic and operating characteristics. The Water Infrastructure segment focuses on the transportation and treatment of water, offering a range of products including water and wastewater pumps, treatment equipment, and controls and systems. The Applied Water segment serves many of the primary uses of water and focuses on the residential, commercial and industrial markets. The Applied Water segment’s major products include pumps, valves, heat exchangers, controls and dispensing equipment. The Measurement & Control Solutions segment focuses on developing advanced technology solutions that enable intelligent use and conservation of critical water and energy resources as well as analytical instrumentation used in the testing of water. The Measurement & Control Solutions segment's major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and testing equipment.

Additionally, we have Regional selling locations, which consist primarily of selling and marketing organizations and related support services, that offer products and services across our reportable segments. Corporate and other consists of corporate office expenses including compensation, benefits, occupancy, depreciation, and other administrative costs, as well as charges related to certain matters, such as environmental matters that are managed at a corporate level and are not included in the business segments in evaluating performance or allocating resources.

28

The accounting policies of each segment are the same as those described in the summary of significant accounting policies (see Note 1 in the 2016 Annual Report). The following tables contain financial information for each reportable segment:

Overview

Xylem is a leading global water technology company. We design, manufacture and service highly engineered solutions ranging across a wide variety of critical applications. Our broad portfolio of solutions addresses customer needs across the water cycle, from the delivery and use of drinking water to the collection and treatment of wastewater to the return of water to the environment. Our product and service offerings are organized into three reportable segments that are aligned around the critical market applications they provide: Water Infrastructure, Applied Water and Measurement & Control Solutions (formerly Sensus & Analytics).

As previously announced, in the second quarter of 2017 we implemented an organizational redesign by moving Xylem’s Analytics business from our Water Infrastructure business to combining it with our Sensus business, which was acquired in the fourth quarter of 2016, to form Measurement & Control Solutions. We believe that the combination of these businesses will enhance our focus on advanced sensing technologies and will lead to operating efficiencies by integrating the supply chain process and moving to a leaner functional structure.

31

 Accordingly, our reportable segments have changed. Beginning with the second quarter of 2017, the Company now reports the financial position and results of operations of its Analytics and Sensus businesses as one new reportable segment, which is called Measurement & Control Solutions . Our Water Infrastructure reportable segment no longer includes the results of our Analytics business. The Company has recast certain historical amounts between the Company's Water Infrastructure and Measurement & Control Solutions reportable segments, however this change had no impact on the Company's historical consolidated financial position or results of operations. The recast financial information does not represent a restatement of previously issued financial statements. Our Applied Water reportable segment remains unchanged.

• Water Infrastructure serves the water infrastructure sector with pump systems that transport water from aquifers, lakes, rivers and seas; with filtration, ultraviolet and ozone systems that provide treatment, making the water fit to use; and pumping solutions that move the wastewater to treatment facilities where our mixers, biological treatment, monitoring and control systems provide the primary functions in the treatment process. In the Water Infrastructure segment, we provide the majority of our sales directly to customers with strong applications expertise, while the remaining amount is through distribution partners.

• Applied Water serves the usage applications sector with water pressure boosting systems for heating, ventilation and air conditioning and for fire protection systems to the residential and commercial building services markets. In addition, our pumps, heat exchangers, valves and controls provide cooling to power plants and manufacturing facilities, as well as circulation for food and beverage processing. We also provide boosting systems for farming irrigation and pumps for dairy operations. In the Applied Water segment, we provide the majority of our sales through long-standing relationships with many of the leading independent distributors in the markets we serve, with the remainder going directly to customers.

• Measurement & Control Solutions primarilyserves the utility infrastructure solutions and services sector by delivering communications, smart metering, measurement and control technologies and services that allow customers to more effectively use their distribution networks for the delivery of critical resources such as water, electricity and natural gas. In the Measurement & Control Solutions segment, we also provide analytical instrumentation used to measure water quality, flow and level in wastewater, surface water and coastal environments. Additionally, we sell software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and we also sell smart lighting products and solutions that improve efficiency and public safety efforts across communities. In the Measurement & Control Solutions segment we generate our sales through a combination of long-standing relationships with leading distributors and dedicated channel partners as well as direct sales depending on the regional availability of distribution channels and the type of product.

Executive Summary

Xylem reported revenue for the third quarter of 2017 of $1,195 million, an increase of 33.2% compared to $897 million reported in the third quarter of 2016. On a constant currency basis, revenue increased 30.8% mostly due to $234 million of revenue related to the Sensus business acquisition and organic revenue growth of $44 million driven by growth in all end markets.

Operating income for the third quarter of 2017 was $152 million, reflecting an increase of 39.4% compared to $109 million in the third quarter of 2016. Operating margin was 12.7% for 2017 versus 12.2% for 2016, an increase of 50 basis points. The increase in operating margin was primarily due to cost reductions resulting from progress in our global procurement and productivity initiatives, restructuring savings and a decrease in Sensus acquisition related costs and restructuring and realignment charges. These favorable impacts on operating margin were largely offset by cost inflation increases, Sensus purchase accounting impacts and special charges.

Adjusted operating income was $169 million with an operating margin of 14.1% in 2017 as compared to adjusted operating income of $131 million with an adjusted operating margin of 14.6% in the third quarter of 2016. The decrease in adjusted operating margin was mostly due to cost inflation increases and Sensus purchase accounting impacts which were partially offset by cost reductions resulting from progress in our global procurement and productivity initiatives and restructuring savings. The non-cash Sensus purchase accounting impact on adjusted operating margin for the quarter was 70 basis points, which if excluded would bring the adjusted operating margin to 14.8%, a 20 basis point increase over the prior year.

32

Additional financial highlights for the quarter ended September 30, 2017 include the following:

• Orders of $1,249 million, up 32.0% from $946 million in the prior year, up 6.1% on an organic basis

• Earnings per share of $0.58, up 41.5% from the prior year ($0.65, up 20.4% on an adjusted basis)

• Cash flow from operating activities of $379 million for the nine months ended September 30, 2017, up 38.3% from the prior year, and free cash flow, excluding Sensus acquisition related costs, of $283 million as compared to $187 million, up 51.3% from the prior year

Key Performance Indicators and Non-GAAP Measures

Management reviews key performance indicators including revenue, gross margin, segment operating income and margins, earnings per share, orders growth, working capital and backlog, among others. In addition, we consider certain non-GAAP (or “adjusted”) measures to be useful to management and investors evaluating our operating performance for the periods presented, and provide a tool for evaluating our ongoing operations, liquidity and management of assets. This information can assist investors in assessing our financial performance and measures our ability to generate capital for deployment among competing strategic alternatives and initiatives, including, but not limited to, dividends, acquisitions, share repurchases and debt repayment. Excluding revenue, Xylem provides guidance on a non-GAAP basis due to the inherent difficulty in forecasting certain amounts that would be included in GAAP earnings, such as discrete tax items, without unreasonable effort. These adjusted metrics are consistent with how management views our business and are used to make financial, operating and planning decisions. These metrics, however, are not measures of financial performance under GAAP and should not be considered a substitute for revenue, operating income, net income, earnings per share (basic and diluted) or net cash from operating activities as determined in accordance with GAAP. We consider the following non-GAAP measures, which may not be comparable to similarly titled measures reported by other companies, to be key performance indicators:

• "organic revenue" and "organic orders" defined as revenue and orders, respectively, excluding the impact of fluctuations in foreign currency translation and contributions from acquisitions and divestitures. Divestitures include sales of insignificant portions of our business that did not meet the criteria for classification as a discontinued operation. The period-over-period change resulting from foreign currency translation impacts is determined by translating current period and prior period activity using the same currency conversion rate.

• "constant currency" defined as financial results adjusted for foreign currency translation impacts by translating current period and prior period activity using the same currency conversion rate. This approach is used for countries whose functional currency is not the U.S. Dollar.

• "adjusted net income" and "adjusted earnings per share" defined as net income and earnings per share, respectively, adjusted to exclude restructuring and realignment costs, Sensus acquisition related costs, special charges, tax-related special items and gain from sale of business, as applicable. A reconciliation of adjusted net income is provided below.

• "operating expenses excluding restructuring and realignment costs, Sensus acquisition related costs and special charges" defined as operating expenses, adjusted to exclude restructuring and realignment costs, Sensus acquisition related costs and special charges.

• "adjusted operating income" defined as operating income, adjusted to exclude restructuring and realignment costs, Sensus acquisition related costs and special charges, and "adjusted operating margin" defined as adjusted operating income divided by total revenue.

• “realignment costs” defined as costs not included in restructuring costs that are incurred as part of actions taken to reposition our business, including items such as professional fees, severance, relocation, travel, facility set-up and other costs.

• "Sensus acquisition related costs" defined as costs incurred by the Company associated with the acquisition of Sensus that are being reported within operating income. These costs include transaction costs, integration costs and costs related to the recognition of the backlog intangible asset recorded in purchase accounting.

• “special charges" defined as costs incurred by the Company, such as non-cash impairment charges, due diligence costs, initial acquisition costs not related to Sensus and other special non-operating items, as well as interest expense related to the early extinguishment of debt and financing costs on the bridge loan entered into for the Sensus acquisition during 2016.

• "tax-related special items" defined as tax items, such as tax return versus tax provision adjustments, tax exam impacts, tax law change impacts, significant reserves for cash repatriation, excess tax benefits/losses and other discrete tax adjustments.

• "free cash flow" defined as net cash from operating activities, as reported in the statement of cash flow, less capital expenditures, as well as adjustments for other significant items that impact current results which management believes are not related to our ongoing operations and performance. Our definition of free cash flow does not consider certain non-discretionary cash payments, such as debt. The following table provides a reconciliation of free cash flow.

2017 Outlook

We anticipate total revenue growth in the range of 24% to 25% in 2017 with organic revenue growth in the low-single-digits and the Sensus acquisition contributing most of the additional revenue growth. The following is a summary of our organic revenue outlook by end market.

• Industrial market revenue was up low-single-digits on an organic basis through the third quarter. We expect oil and gas and mining markets to stabilize in North America through the balance of the year, and we expect market conditions in the United States to improve modestly throughout the remainder of the year. As a result, we expect organic revenue of low-single-digits for 2017.

• Public utility revenue declined slightly through the September on an organic basis, primarily due to a difficult comparison to double-digit growth in the United States in the prior year.  We expect organic revenue growth in the low-single-digits for 2017 with project activity fueling growth in emerging markets, primarily in China and India. We also anticipate revenue from Sensus to contribute mid-single-digit growth over their historical performance, driven by expected project deployments and traction from new products. On a pro forma basis that includes Sensus, we expect organic revenue growth of low to mid-single-digits for 2017.

• In the commercial markets, organic growth was approximately 5% through the September, primarily driven by growth in the United States. In 2017 we expect organic revenue growth in the mid-single-digit range as we see the United States market continuing to be strong while the European market is experiencing growth related to new energy efficient products and sales channel investments.

• In residential markets, organic growth was into the low-double-digits through the third quarter primarily driven by strength in the United States and Asia Pacific. In 2017 we expect full year organic revenue performance will be up in the high-single-digits. We continue to expect the United States market to be competitive given the replacement nature of the sector we serve. We expect growth from the European market, which looks to be modestly stronger as increased residential building permitting provides an indicator of sales. Additionally, we expect to benefit from market share gains from channel disruption throughout the remainder of the year.

We will continue to strategically execute restructuring and realignment actions primarily to reposition our European and North American business in an effort to optimize our cost structure and improve our operational efficiency and effectiveness. During 2017, we expect to incur approximately $50 million in restructuring and realignment costs, as well as Sensus acquisition related costs. We expect to realize approximately $20 million of

35

incremental net savings in 2017 from actions initiated in 2016, and an additional $6 million of net savings from our 2017 actions.

Additional strategic actions we are taking include strategic initiatives to drive above-market growth, advance continuous improvement activities to increase productivity, focus on improving cash performance and drive a disciplined capital deployment strategy. Additionally, with the acquisition of Sensus, we anticipate increased spending on research and development as a percentage of revenue as Sensus brings a higher profile of R&D given the investment required to support growth and new product launches.

Revenue

Revenue generated during the three and nine months ended September 30,2017 was $1,195 million and $3,430 million, reflecting increases of $298 million or 33.2% and $754 million or 28.2%, respectively, compared to the same prior year periods. On a constant currency basis, revenue grew 30.8% and 28.3% for the three and nine months ended September 30,2017, respectively. These increases in revenue were primarily driven by an additional $234 million and $715 million, respectively, of revenue from the businesses acquired in the fourth quarter of 2016. Organic revenue increased from the prior year by $44 million and $47 million for the three and nine months ended September 30, 2017, respectively. These increases reflect strong organic growth in emerging markets for both periods, particularly in Asia Pacific, as well as strength in North America for both periods. There was also organic growth in the quarter for western Europe; however, this region had slight organic declines year-to-date, driven by the United Kingdom.

(a) Foreign currency translation impact for the quarter due to fluctuations in the value of various currencies against the U.S. Dollar, primarily the Euro followed by Canadian Dollar, the Swedish Krona and the Australian Dollar.

(b) Foreign currency translation impact for the nine months due to fluctuations in the value of various currencies against the U.S. Dollar, the largest being British Pound which was partially offset by the Euro and the South African Rand.

Water Infrastructure

Water Infrastructure revenue increased $42 million, or 8.8%, for the third quarter of 2017 (6.7% increase at constant currency) and increased $19 million, or 1.4%, for the nine months ended September 30, 2017 (1.7% increase at constant currency) as compared to 2016. Revenue benefited from $10 million of foreign currency translation for the three months ended September 30, 2017 and was negatively impacted by $5 million from foreign currency translation for nine months ended September 30, 2017. The change at constant currency included organic growth of $32 million, or 6.7%, in the third quarter and organic growth of $24 million, or 1.7%, for the nine months ended September 30, 2017. Organic growth for the quarter was driven by strength in the industrial end market, particularly in North America and the emerging markets, which was partially offset by declines in Europe. Organic growth for the quarter was also driven by strength in the public utility end market, particularly in the Middle East and Africa, Europe and North America. This growth was partially offset by public utility declines in Asia Pacific. For the nine months ended September 30, 2017, organic growth was driven by continued improvement in the industrial end market, particularly in the emerging markets as well as North America. Public utility declined organically year-to-date driven by reductions in municipal spending in western Europe and difficult comparisons to the prior year in the United States where we had double digit growth rates in the United States.

From an application perspective for the third quarter of 2017, organic revenue growth was driven by our transport applications in the industrial end market due to strength in the dewatering business which benefited from distribution strength and improved construction, oil and gas, and mining markets, particularly in North America.

37

The treatment application also had strong industrial growth driven by strong project deliveries in the emerging markets.

For the nine months ended September 30, 2017, organic revenue growth was driven primarily by our transport application in the industrial end market due to strength in the dewatering business which benefited from a strong distribution channel and improved mining markets, primarily in Latin America and the United States. Our treatment application had flat overall organic revenue with growth in the industrial end markets, primarily in Asia Pacific, offset by declines in public utility driven by a difficult prior year comparison in the United States, as well as slower bidding activity in the Middle East where the oil and gas market downturn impacted municipal spending.

Applied Water

Applied Water revenue increased $11 million, or 3.2%, for the third quarter of 2017 (1.7% increase at constant currency) and increased $6 million, or 0.6%, for the nine months ended September 30, 2017 (1.1% increase at constant currency) compared to the respective 2016 periods. Revenue benefited by $5 million due to foreign currency translation for the three months ended September 30, 2017 and was negatively impacted by $5 million due to foreign currency translation for nine months ended September 30, 2017. The revenue growth included organic growth of $8 million, or 2.3%, in the third quarter of 2017 and $16 million, or 1.5%, for the nine months ended September 30, 2017, which was driven by growth in commercial and residential end markets, partially offset by declines in the industrial market.

From an application perspective, organic revenue growth in the third quarter of 2017 was led by growth in commercial building services, driven by strength in North America and Europe as well as project deliveries in China. Residential building service revenue also grew organically, primarily driven by continued strength in Asia Pacific from demand for second water supply sourcing. This organic growth was partially offset by a decline in industrial applications, primarily driven by unfavorable weather conditions impacting the agriculture business in the United States.

For the nine months ended September 30, 2017, growth in residential building services was primarily driven by strength in the United States, where we benefited from timing of promotions and modest share gains, and continue strength in Asia Pacific. Commercial building services also grew, primarily in North America, Asia Pacific and Europe, driven by new product traction and sales channel investments. This growth was partially offset by a decline in industrial applications, primarily driven by weaker than expected industrial market conditions in the United States, partially offset by strength in western Europe.

Measurement & Control Solutions

Measurement & Control Solutions revenue increased $245 million, or 322.5%, for the third quarter of 2017 (313.2% at constant currency) and increased $729 million, or 314.2%, for the nine months ended September 30, 2017 (311.2% at a constant currency) compared to the respective 2016 periods. The revenue increase for the three and nine months ended September 30, 2017 was almost entirely made up of the revenue contributed by the fourth quarter 2016 acquisitions, primarily Sensus, of $234 million and $715 million, respectively. Over 65% of the Sensus revenue was generated in the United States with additional revenue coming primarily from western Europe and China. The majority of Sensus revenue came from water applications with gas and electric applications making up most of the remaining sales in both periods. Organic revenue growth in the Measurement & Control Solutions segment was $4 million, or 5.3%, and $7 million, or 3.0%, for the three and nine months ended September 30, 2017, respectively. The organic growth in both periods was driven by strength in the test applications primarily from the environmental monitoring business in the United States.

Orders / Backlog

Orders received during the third quarter of 2017 were $1,249 million, an increase of $303 million, or 32.0%, over the third quarter of the prior year (29.7% increase at constant currency). Orders received during the nine months ended September 30, 2017 were $3,598 million, an increase of $841 million, or 30.5%, from the prior year (30.6% increase at constant currency). The order growth at constant currency was primarily driven by additional orders from the fourth quarter 2016 acquisitions of $225 million and $688 million, as well as organic order growth of 6.1% and 5.7%, for the three and nine months ended September 30,2017, respectively.

Water Infrastructure segment orders increased $37 million, or 7.1%, to $558 million (4.8% increase at constant currency) for the quarter as compared to the same prior year period. The order increase on a constant currency basis consisted entirely of an increase in organic orders. Organic order growth spanned all of the applications. The transport applications had growth driven by increased strength in dewatering from distributor order strength

38

and increased weather related activity in North America. This growth was partially offset by organic declines against a strong prior year for transport applications in emerging markets as there was a large project booking in our wastewater transport business the prior year. Treatment applications had strong order intake, primarily from a large project wins in the United States, as well as order strength in Europe.

For the nine months ended September 30, 2017 orders increased $81 million, or 5.5%, to $1,546 million (5.8% increase at constant currency) as compared to the same prior year period. The order increase on a constant currency basis consisted entirely of an increase in organic orders. Organic order growth spanned all applications. The transport applications had year-to-date organic order growth driven by growth in the United States for transport projects and dewatering distributor orders, as well as strong project orders in China and India and dewatering rental strength in Latin America from increased mining activity. Treatment applications had strong order intake in North America and the emerging markets, as well as western Europe.

Applied Water segment orders increased $32 million, or 9.4%, to $374 million (8.2% increase at constant currency) for the third quarter as compared to the same prior year period. The order increase for the third quarter on a constant currency basis included organic order growth of 8.8% driven by strong commercial performance in the United States and strength in the emerging markets. For the nine months ended September 30, 2017 orders increased $46 million, or 4.4%, to $1,103 million (4.9% increase at constant currency) as compared to the same prior year period. The order increase on a constant currency basis included organic order growth of 5.4% driven by strength in the emerging markets, strong residential and commercial performance in the United States as well as industrial strength in the Americas.

Measurement & Control Solutions segment orders increased $234 million, or 281.9%, to $317 million (274.7% increase at constant currency) for the third quarter of 2017 as compared to the same prior year period. The order increase included orders from recent acquisitions, mostly Sensus, of $225 million and organic order growth of $3 million, or 3.6% from test application strength in China and the United States. For the nine months ended ended September 30, 2017 orders increased $714 million, or 303.8%, to $949 million (301.3% increase at constant currency) as compared to the same prior year period and included orders from recent acquisitions, primarily Sensus, of $693 million and organic order growth of $15 million, or 6.4% from test application strength in the United States and China.

Backlog includes orders on hand as well as contractual customer agreements at the end of the period. Delivery schedules vary from customer to customer based on their requirements. Annual or multi-year contracts are subject to rescheduling and cancellation by customers due to the long-term nature of the contracts. As such, beginning total backlog, plus orders, minus revenues, will not equal ending total backlog due to contract adjustments, foreign currency fluctuations, and other factors. Typically, large projects require longer lead production cycles and deployment schedules and delays can occur from time to time. Total backlog was $1,556 million at September 30, 2017, an increase of $781 million or 100.8% as compared to September 30, 2016, which did not include the Sensus acquisition, and an increase of $264 million or 20.4%, as compared to December 31, 2016 backlog of $1,292 million. The December 31, 2016 backlog balance has been revised to include contractual agreements that Sensus has with customers that do not have minimum commitments but which we believe will be executed upon over the terms of the contracts. We anticipate that approximately 40% of the backlog at September 30, 2017 will be recognized as revenue in the remainder of 2017.

Gross Margin

Gross margin as a percentage of revenue decreased 40 basis points to 39.4% and 30 basis points to 39.1%, respectively, for the three and nine months ended September 30,2017, compared to 39.8% and 39.4%, respectively, for comparative 2016 periods. The gross margin declines were driven by cost inflation, unfavorable mix and Sensus gross margins, which include unfavorable purchase accounting impacts. The negative impacts to gross margin were largely offset by cost reductions from global procurement and continuous improvement initiatives.

Expense to revenue ratio	26.7		%	27.6		%	(90	)	bp	28.1		%	28.3		%	(20	)	bp

Selling, General and Administrative Expenses

SG&A increased by $51 million to $270 million or 22.6% of revenue in the third quarter of 2017, as compared to $219 million or 24.4% of revenue in the comparable 2016 period; and increased by $147 million to $812 million or 23.7% of revenue in the nine months ended September 30, 2017, as compared to $665 million or 24.9% of revenue for the nine months ended in 2016. The increases in SG&A expenses include approximately $49 million and $145 million of additional SG&A spending for the Sensus business, respectively. Additionally we have incurred Sensus acquisition related costs of $5 million and $19 million for the three and nine months ended September 30, 2017, respectively versus $10 million in both comparative prior year periods. Excluding these impacts, SG&A expenses increased by $7 million over the three months as inflation increases, spending on strategic investments and negative currency impacts were only partially offset by savings from restructuring actions and global procurement and continuous improvement initiatives. For the nine month period, excluding the the Sensus acquisition impacts, SG&A expenses decreased by $7 million as savings from global procurement and continuous improvement initiatives and restructuring actions more than offset inflation increases and spending on strategic investments.

Research and Development Expenses

R&D spending was $45 million or 3.8% of revenue in the third quarter of 2017 as compared to $23 million or 2.6% of revenue in the comparable period of 2016; and was $131 million or 3.8% of revenue in the nine months ended September 30, 2017 as compared to $75 million or 2.8% of revenue in the comparable period of 2016. The increase in R&D spending for the three and nine months ended September 30, 2017 was primarily due to higher rates of investment in new products and technology, primarily within our most recently acquired Sensus business, and to drive revenue growth synergies between Xylem and the Sensus business.

Restructuring Charges and Asset Impairment

Restructuring

During the three and nine months ended September 30,2017, we recognized restructuring charges of $4 million and $17 million, respectively. We incurred these charges related to actions taken in 2017 primarily as a continuation of our efforts to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water and Water Infrastructure segments, as well as headcount reductions within our Measurement & Control Solutions segment. Included in the charges recorded during the three and nine months ended September 30,2017 were $1 million and $8 million, respectively, related to actions commenced in prior years.

During the three and nine months ended September 30,2016, we recognized restructuring charges of $6 million and $18 million, respectively. We incurred these charges related to actions taken in 2016 primarily in an effort to reposition our European and North American businesses to optimize our cost structure and improve our

40

operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water and Water Infrastructure segments, as well as Corporate headcount reductions. Included in the charges recorded during the three and nine months ended September 30, 2016 were $1 million related to actions commenced in prior years.

The Water Infrastructure, Applied Water, and Measurement & Control Solutions actions commenced in 2017 consist primarily of severance charges and are expected to continue through the end of 2018. The Water Infrastructure, Applied Water, Measurement & Control Solutions and Corporate actions commenced in 2016 consist primarily of severance charges and are expected to continue through the end of 2018.

We currently expect to incur approximately $20 million in restructuring costs for the full year. As a result of all of the actions taken and expected to be taken in 2017, we anticipate approximately $5 million of total net savings to be realized during 2017.

Asset Impairment

During the first quarter of 2017 we determined that certain assets within our Applied Water segment, including a tradename were impaired. Accordingly we recognized an impairment charge of $5 million. Refer to Note 9, "Goodwill and Other Intangible Assets," for additional information.

Operating Income

We generated operating income of $152 million (margin of 12.7%) during the third quarter of 2017, a $43 million increase compared to $109 million (margin of 12.2%) in 2016. The increase in operating income was largely driven by the inclusion of Sensus operating income in the current year. Additionally, the increase in operating income and operating margin was primarily due to cost reductions from our global procurement and productivity initiatives, favorable volume impacts, restructuring savings and a decrease in Sensus acquisition related costs and restructuring and realignment charges. These favorable impacts on operating income and operating margin were largely offset by cost inflation increases, spending on strategic investments and Sensus purchase accounting impacts.

Adjusted operating income was $169 million (adjusted margin of 14.1%) during the third quarter of 2017 as compared to $131 million (adjusted margin of 14.6%) in 2016. The increase in operating income of $38 million was largely driven by the inclusion of Sensus operating income in the current year. The decrease in adjusted operating margin was mostly due to cost inflation increases, spending on strategic initiatives and Sensus purchase accounting impacts, which were partially offset by cost reductions from global procurement and

41

productivity initiatives, favorable volume impacts and restructuring savings. The non-cash Sensus purchase accounting impact on adjusted operating margin for the quarter was 70 basis points.

We generated operating income of $377 million (margin of 11.0%) during the nine months ended September 30, 2017, an $80 million increase compared to the $297 million (margin of 11.1%) in 2016. The increase in operating income was largely driven by the inclusion of Sensus operating income in the current year. Sensus acquisition related costs and special charges increased $9 million and $3 million, respectively, while restructuring and realignment costs remained flat as compared to the nine months ended September 30, 2016. Excluding these costs, adjusted operating income was $436 million (adjusted margin of 12.7%) for the nine months ended September 30, 2017 as compared to $344 million (adjusted margin of 12.9%) in 2016. Adjusted operating margin was negatively impacted by several factors with cost inflation, Sensus operating margins which include unfavorable purchase accounting impacts and unfavorable product mix being among the largest. These negative impacts on adjusted operating margin were largely offset by cost savings from our global procurement and productivity initiatives, as well as restructuring savings and favorable volume impacts. The non-cash Sensus purchase accounting impact on adjusted operating margin for the year-to-date period was 70 basis points.

Water Infrastructure

Operating income for our Water Infrastructure segment increased $16 million, or 21.3%, for the third quarter of 2017 compared to the prior year, with operating margin also increasing from 15.7% to 17.5%. Operating margin was positively impacted by decreased restructuring and realignment costs of $2 million in 2017. Excluding these restructuring and realignment costs, adjusted operating income increased $14 million, or 17.5%, with adjusted operating margin increasing from 16.7% to 18.1%. The increase in adjusted operating margin for the quarter was primarily due to cost reductions from global procurement and continuous improvement initiatives, favorable volume, as well as restructuring savings, which were partially offset by cost inflation increases, spending on strategic investments and negative transactional currency impacts.

For the nine months ended September 30, 2017, operating income increased $13 million, or 6.8%, as compared to the prior year, with operating margin also increasing from 13.7% to 14.4%. Operating margin was positively impacted by special charges of $2 million in 2016 that did not recur and decreased restructuring and realignment costs of $2 million in 2017 compared with the prior year. Excluding these items, adjusted operating income increased $9 million, or 4.3%, with adjusted operating margin increasing from 14.8% to 15.3%.The increase in adjusted operating margin was primarily due to cost reductions from global procurement and continuous improvement initiatives as well as restructuring savings and favorable volume. These drivers were partially offset by increases in cost inflation and spending on strategic investments, as well as negative transactional currency impacts.

Applied Water

Operating income for our Applied Water segment increased $1 million, or 2.0%, for the third quarter of 2017 compared to the prior year, with operating margin decreasing from 14.6% to 14.4%. Operating margin was negatively impacted by increased restructuring and realignment costs of $2 million. Excluding restructuring and realignment costs, adjusted operating income increased $3 million, or 5.7%, with adjusted operating margin increasing from 15.5% to 15.8%. The increase in adjusted operating margin was primarily due to cost reductions from our global procurement and continuous improvement initiatives and restructuring savings, which were partially offset by increases in cost inflation and spending on strategic initiatives, as well as unfavorable impacts from mix, price and transactional currency.

For the nine months ended September 30, 2017, operating income decreased $4 million, or 2.9%, as compared to the prior year, with operating margin also decreasing from 13.4% to 13.0%. Operating margin was negatively impacted by higher special charges for a non-cash impairment of $5 million and increased restructuring and realignment costs of $5 million. Excluding these items, adjusted operating income increased $6 million, or 4.0%, with adjusted operating margin increasing from 14.3% to 14.8%. The increase in adjusted operating margin was primarily due to cost reductions from global procurement and continuous improvement initiatives, which were partially offset by increases in cost inflation and unfavorable mix and currency impacts.

Measurement & Control Solutions

Operating income for our Measurement & Control Solutions segment increased $22 million, or 550.0%, for the third quarter of 2017 compared to the prior year, primarily due to the inclusion of Sensus operating income of in the current year results, with operating margin also increasing from 5.3% to 8.1%. Operating margin was negatively impacted by $4 million of Sensus acquisition related costs incurred during the quarter which were partially offset by $3 million related to special charges in 2016 that did not recur. Excluding these items, adjusted operating income increased $23 million, or 287.5%, with most of the increase coming from the inclusion of the operating income for Sensus in the current year. Adjusting operating margin decreased from 10.5% to 9.7%. The decrease in adjusted operating margins was largely due to the inclusion of Sensus margins, which are negatively impacted by purchase accounting, and unfavorable mix, which is partially offset by cost reductions from global procurement and continuous improvement initiatives and restructuring savings. Non-cash Sensus purchase accounting negatively impacted the segment's operating margin in the quarter by 230 basis points.

For the nine months ended September 30, 2017, operating income increased $69 million, or 627.3%, as compared to the prior year,primarily due to the inclusion of Sensus operating income of in the current year results, with operating margin also increasing from 4.7% to 8.3%. Operating margin was negatively impacted by $13 million of Sensus acquisition related costs which were partially offset by $3 million related to special charges in 2016 that did not recur, as well as a $1 million decrease in restructuring and realignment costs. Excluding these items, adjusted operating income increased $78 million, or 371.4%,with most of the increase coming from the inclusion of the operating income for Sensus in the current year. Adjusted operating margin increased from 9.1%

44

to 10.3%. The increase in adjusted operating income and margin was primarily due to cost reductions from global procurement and continuous improvement initiatives, restructuring savings as well as volume and other favorable impacts, which were partially offset by unfavorable mix and the inclusion of Sensus margins, which were negatively impacted by purchase accounting. Non-cash Sensus purchase accounting negatively impacted the segment's year-to-date operating margin in the quarter by 230 basis points.

Corporate and other

Operating expense for corporate and other decreased $4 million for the third quarter of 2017 as compared to the prior year, primarily due to a $9 million decrease in Sensus acquisition related costs. This was partially offset by $3 million of special charges incurred during the current quarter. Excluding these costs, adjusted operating expense increased $2 million for the quarter, mostly driven by increased employee related costs. For the nine months ended September 30, 2017 operating expense decreased $2 million as compared with the prior year. This decrease in operating expense was primarily due to a decrease of Sensus acquisition related costs and a reduction in restructuring and realignment costs, which were partially offset by an increase in special charges as compared to the prior year. Excluding these costs, adjusted operating expense for corporate and other was essentially flat for the nine months ended September 30, 2017 as compared to 2016.

Interest Expense

Interest expense was $21 million and $62 million for the three and nine months ended September 30, 2017, and $16 million and $50 million for the three and nine months ended September 30, 2016. The increased interest expense for the three and nine month periods includes additional interest expense in 2017 related to debt entered into in the third quarter of 2016 to fund our acquisition of Sensus. The increase in interest expense was partially offset by the reduction in special interest charges of $8 million and $4 million that were incurred in the second quarter of 2016 in connection with the early extinguishment of our Senior Notes due in 2016 and financing charges on the bridge loan related to the Sensus acquisition in the third quarter of 2016, respectively, neither of which recurred in 2017. See Note 12, "Credit Facilities and Debt" of our consolidated financial statements for a description of our credit facilities and long-term debt and related interest.

Income Tax Expense

The income tax provision for the three months ended September 30, 2017 was $27 million resulting in an effective tax rate of 21.1%, compared to $22 million resulting in an effective tax rate of 22.9% for the same period in 2016. The income tax provision for the nine months ended September 30, 2017 was $62 million resulting in an effective tax rate of 19.4%, compared to $40 million resulting in an effective tax rate of 16.0% for the same period in 2016. The effective tax rate was lower than the United States federal statutory rate primarily due to the mix of earnings in jurisdictions in both periods. Additionally, the effective tax rate for the nine months ended September 30, 2016 was lower than the current period due to the release of an unrecognized tax benefit in 2016 related to the effective settlement of a tax examination offset in part by the nonrecurring repatriation of foreign earnings from 2016.

Other Comprehensive Income

Other comprehensive income was $21 million for the three months ended September 30, 2017 compared to a loss of $3 million for the same period in2016. This increase in other comprehensive income was driven primarily by favorable foreign currency translation impacts, primarily due to the strengthening of the Great British Pound and the Canadian Dollar against the U.S. Dollar in 2017 as compared to the weakening of these currencies in the prior year. Additionally, the Euro continued to strengthen as compared to the U.S. Dollar year over year for the quarter, which was partially mitigated by the Euro movement on the Company's net investment hedge during the same period. The tax impact on the foreign currency translation related to the net investment hedge also contributed to the year over year increase.

For the nine months ended September 30, 2017 Other comprehensive income was $119 million as compared to a loss of $17 million for the same period in 2016. This increase was driven primarily by favorable foreign currency translation impacts, primarily due to the increased strengthening of the Euro and Brazilian Real against the U.S. Dollar as compared to the prior year. Additionally, the strengthening of the Great British Pound against the U.S. Dollar in the current year as compared to the weakening of this currency in the prior year. Partially offsetting these favorable movements, was the Euro movement on the Company's net investment hedge as compared to the prior year. The tax impact on the foreign currency translation related to the net investment hedge also contributed to the year over year increase.

(a) The impact is primarily due to the strengthening of the Euro against the U.S. Dollar.

Sources and Uses of Liquidity

Operating Activities

During the nine months ended September 30, 2017, net cash provided by operating activities increased by $105 million as compared to the same prior year period. The year-over-year increase was primarily driven by increased cash from the operating activities of the Sensus business acquired in the fourth quarter of 2016. This increase was partially offset by increased use of working capital as well as increased payments for restructuring charges and interest as compared to the prior year.

Investing Activities

Cash used in investing activities was $122 million for the nine months ended September 30, 2017 as compared to $155 million in the comparable prior year period. This decrease was mainly driven by the $70 million spent on the acquisition of Tideland Signal Corporation during the nine months ended September 30, 2016 versus the $16 million spent for acquisitions in 2017. Additionally, we received $10 million of proceeds from the sale of a business we divested in the first quarter of 2017, which was offset by increased spending of $29 million over the prior year on capital projects, including spending on capitalized software in the Sensus business.

Financing Activities

Cash used by financing activities was $299 million for the nine months ended September 30, 2017 as compared to cash used of $150 million in the comparable prior year period. The net increase in cash used by financing activities was primarily driven by increases in cash used for repayment of debt, net of debt issuance proceeds in the prior year, increases in share repurchase activity of $22 million to offset dilution, reductions to proceeds from stock option exercises of $14 million, and an increase in dividends paid of $13 million.

Funding and Liquidity Strategy

Our ability to fund our capital needs depends on our ongoing ability to generate cash from operations, and access to bank financing and the capital markets. Historically, we have generated operating cash flow sufficient to fund our primary cash needs centered on operating activities, working capital, capital expenditures, and strategic investments. If our cash flows from operations are less than we expect, we may need to incur debt or issue equity. From time to time, we may need to access the long-term and short-term capital markets to obtain financing. Our access to, and the availability of, financing on acceptable terms and conditions in the future will be impacted by many factors, including: (i) our credit ratings or absence of a credit rating, (ii) the liquidity of the overall capital markets, and (iii) the current state of the economy. There can be no assurance that such financing will be available to us on acceptable terms or that such financing will be available at all.

We monitor our global funding requirements and seek to meet our liquidity needs on a cost effective basis. Based on our current global cash positions, cash flows from operations and access to the commercial paper markets, we believe there is sufficient liquidity to meet our funding requirements.  In addition, our existing committed credit facilities and access to the public debt markets would provide further liquidity if required.

We anticipate that our present sources of funds, including funds from operations and additional borrowings, will provide us with sufficient liquidity and capital resources to meet our liquidity and capital needs in both the United States and outside of the United States over the next twelve months.

Credit Facilities & Long-Term Contractual Commitments

See Note 12, "Credit Facilities and Debt" of our consolidated financial statements for a description of our credit facilities and long-term debt.

Non-U.S. Operations

We generated approximately 53% and 54% of our revenue from non-U.S. operations for the three and nine months ended September 30,2017 and 59% for the three and nine months ended September 30, 2016. As we continue to grow our operations in the emerging markets and elsewhere outside of the United States, we expect to continue to generate significant revenue from non-U.S. operations and we expect a substantial portion of our cash will be predominately held by our foreign subsidiaries. We expect to manage our worldwide cash requirements considering available funds among the many subsidiaries through which we conduct business and the cost effectiveness with which those funds can be accessed. We may transfer cash from certain international subsidiaries to the U.S. and other international subsidiaries when we believe it is cost effective to do so. We continually review our domestic and foreign cash profile, expected future cash generation and investment opportunities, which support our current designation of a portion of these funds as being indefinitely reinvested and reassess whether there is a demonstrated need to repatriate funds held internationally to support our U.S. operations. If, as a result of our review, it is determined that all or a portion of the funds may be needed for our operations in the United States, we may be required to accrue additional U.S. taxes. As of September 30, 2017, our foreign subsidiaries were holding $267 million in cash or marketable securities.

Critical Accounting Estimates

Our discussion and analysis of our results of operations and capital resources are based on our condensed consolidated financial statements, which have been prepared in conformity with GAAP. The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities. We believe the most complex and sensitive judgments, because of their significance to the condensed consolidated financial statements, result primarily from the need to make estimates about the effects of matters that are inherently uncertain. Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2016 Annual Report describes the critical accounting estimates used in preparation of the condensed consolidated financial statements. Actual results in these areas could differ from management’s estimates. There have been no significant changes in the information concerning our critical accounting estimates as stated in our 2016 Annual Report.

New Accounting Pronouncements

See Note 2, "Recently Issued Accounting Pronouncements," to the condensed consolidated financial statements for a complete discussion of recent accounting pronouncements. We are currently evaluating the impact of certain recently issued guidance on our financial condition and results of operations in future periods.

Background and Basis of Presentation

Background

Xylem Inc. ("Xylem" or the "Company") is a leading equipment and service provider for water and wastewater applications with a broad portfolio of products and services addressing the full cycle of water, from collection, distribution and use to the return of water to the environment. Xylem was incorporated in Indiana on May 4, 2011.

As previously announced, in the second quarter of 2017 we implemented an organizational redesign by moving Xylem’s Analytics business from our Water Infrastructure business to combining it with our Sensus business, which was acquired in the fourth quarter of 2016, to form Measurement & Control Solutions (formerly Sensus & Analytics). We believe that the combination of these businesses will enhance our focus on advanced sensing technologies and will lead to operating efficiencies by integrating the supply chain process and moving to a leaner functional structure.  Accordingly, our reportable segments have changed. Beginning with the second quarter of 2017, the Company now reports the financial position and results of operations of its Analytics and Sensus businesses as one new reportable segment, which is currently called Measurement & Control Solutions. Our Water Infrastructure reportable segment no longer includes the results of our Analytics business. The Company has recast certain historical amounts between the Company's Water Infrastructure and Measurement & Control Solutions reportable segments, however this change had no impact on the Company's historical consolidated financial position or results of operations. The recast financial information does not represent a restatement of previously issued financial statements. Our Applied Water reportable segment remains unchanged. Refer to Note 18 "Segment Information" for additional segment information.

Xylem operates in three segments, Water Infrastructure, Applied Water and Measurement & Control Solutions. The Water Infrastructure segment focuses on the transportation and treatment of water, offering a range of products including water and wastewater pumps, treatment equipment, and controls and systems. The Applied Water segment serves many of the primary uses of water and focuses on the residential, commercial and industrial markets. The Applied Water segment’s major products include pumps, valves, heat exchangers, controls and dispensing equipment. The Measurement & Control Solutions segment focuses on developing advanced technology solutions that enable intelligent use and conservation of critical water and energy resources as well as analytical instrumentation used in the testing of water. The Measurement & Control Solutions segment's major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and testing equipment.

Except as otherwise indicated or unless the context otherwise requires, "Xylem," "we," "us," "our" and the "Company" refer to Xylem Inc. and its subsidiaries.

Basis of Presentation

The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated.

The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair presentation of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2016 ("2016 Annual Report") in preparing these unaudited condensed consolidated financial statements, with the exception of accounting standard updates described in Note 2. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2016 Annual Report.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, postretirement obligations and assets, revenue recognition, income tax contingency accruals and valuation allowances, goodwill and indefinite lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates.

Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.

Accounting Policies [Abstract]

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

Pronouncements Not Yet Adopted

In August 2017, the Financial Accounting Standards Board (“FASB”) issued amended guidance on hedging activities. The amendment better aligns a company’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying for hedging relationships and the presentation of hedge results. Specifically, the guidance:

(1)Eliminates the concept of recognizing periodic hedge ineffectiveness for cash flow and net investment hedges

(2)Eliminates the benchmark interest rate concept of variable - rate instruments in cash flow hedges and allows companies to designate the contractually specified interest rate as the hedged risk

(3)Requires a company to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported

(4)Provides the ability to perform subsequent hedge effectiveness tests qualitatively

This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted with the effect of adoption reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing at the date of adoption, a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness is required. Other presentation and disclosure guidance is required only prospectively. We are evaluating the impact of the guidance on our financial condition and results of operations.

In March 2017, the FASB issued amended guidance on presentation of net periodic benefit costs.  The amendment requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period.  The other components are required to be presented in the income statement separately and outside a subtotal of income from operations, if one is presented.  The amendment also requires entities to disclose the income statement lines that contain the other components if they are not appropriately described.  This guidance is effective retrospectively for periods beginning after December 15, 2017, including interim periods within those annual periods.  Early adoption is permitted.  The adoption of this guidance is expected to impact the presentation between operating income and other non operating income within Xylem's Consolidated Income Statement but is not expected to have a material impact on our consolidated financial condition or results of operations.

In June 2016, the FASB issued guidance amending the accounting for the impairment of financial instruments, including trade receivables. Under current guidance, credit losses are recognized when the applicable losses are probable of occurring and this assessment is based on past events and current conditions. The amended guidance eliminates the “probable” threshold and requires an entity to use a broader range of information, including forecast information when estimating expected credit losses. Generally, this should result in a more timely recognition of credit losses. This guidance is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted for interim and annual periods beginning after December 15, 2018. The requirements of the amended guidance should be applied using a modified retrospective approach except for debt securities, which require a prospective transition approach. We are evaluating the impact of the guidance on our financial condition and results of operations.

In February 2016, the FASB issued guidance amending the accounting for leases. Specifically, the amended guidance requires all lessees to record a lease liability at lease inception, with a corresponding right of use asset, except for short-term leases. Lessor accounting is not fundamentally changed. This amended guidance is effective for interim and annual periods beginning after December 15, 2018 using a modified retrospective approach. Early adoption is permitted. We are evaluating the impact of the guidance on our financial condition and results of operations.

In May 2014, the FASB issued guidance on recognizing revenue from contracts with customers. The guidance outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the model is that an entity recognizes revenue to portray the transfer of goods and 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. The standard also expands disclosure requirements regarding revenue recognition. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017 and may be applied retrospectively to each prior period presented or using a modified retrospective approach with the cumulative effect recognized as of the date of initial application. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2016. The impact of this guidance on our financial condition and results of operations will be based on the types of contracts that Xylem is awarded in the future. We currently do not believe that the adoption of this guidance will have a material impact on our financial statements and plan to adopt this guidance effective January 1, 2018 using the modified retrospective approach.

Recently Adopted Pronouncements

In May 2017, the FASB issued guidance, which amends the scope of modification accounting guidance for share-based payment arrangements. The guidance outlines the types of changes to the terms or conditions of share-based payment arrangements that would require the use of modification accounting. Specifically, modification accounting would not apply if the fair value, vesting conditions, and classification of the award as equity or liability are the same immediately before and after the modification. This guidance is effective prospectively for interim and annual reporting periods beginning December 15, 2017 and early adoption is permitted. We elected to early adopt this guidance effective the second quarter of 2017. The adoption of this guidance did not impact our financial condition or results from operations.

In January 2017, the FASB issued guidance amending the impairment testing of goodwill. Under current guidance, the testing of goodwill for impairment is performed at least annually using a two-step test. Step one involves comparing the fair value of a “reporting unit” to its carrying amount. If the applicable book value exceeds the reporting unit’s fair value then step two must be performed. Step two involves comparing the fair value of the reporting unit’s goodwill to the applicable carrying amount of the asset and recognizing an impairment charge equal to the amount by which the carrying amount of the goodwill exceeds its implied fair value. The amended guidance eliminates step two of the impairment test and allows an entity to record an impairment charge equal to the amount that the carrying amount of the applicable reporting unit exceeds its fair value, up to the value of the recorded goodwill. This guidance is effective prospectively for interim and annual goodwill impairment tests beginning after December 15, 2019 with early adoption permitted for interim or annual tests after January 1, 2017. We elected to early adopt this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

In October 2016, the FASB issued guidance amending the accounting for income taxes. Under current guidance the recognition of current and deferred income taxes for an intra-entity asset transfer is prohibited until the asset has been sold to an outside party. The amended guidance eliminates the prohibition against immediate recognition of current and deferred income tax amounts associated with intra-entity transfers of assets other than inventory. This guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. The requirements of the amended guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We elected to early adopt this guidance effective the first quarter of 2017. As a result of adopting the amended guidance, prepaid tax assets were reduced by $14 million, long-term deferred tax assets increased $3 million, and accrued taxes were reduced by $4 million. The net impact of these adjustments on retained earnings was a decrease of $7 million.

In July 2015, the FASB issued guidance regarding simplifying the measurement of inventory. Under prior guidance, inventory is measured at the lower of cost or market, where market is defined as replacement cost, with a ceiling of net realizable value and a floor of net realizable value less a normal profit margin. The amended guidance requires the measurement of inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective prospectively for interim and annual periods beginning after December 15, 2016 and early application is permitted. We adopted this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

2017 Acquisitions and Divestitures

Acquisitions

During the three and nine months ended September 30, 2017 we spent approximately $10 million and $16 million, respectively, on various acquisition activity.

Divestitures

On February 17, 2017, we divested our United Kingdom and Poland based membranes business for approximately $10 million. The sale resulted in a gain of $4 million, which is reflected in gain from sale of business in our Condensed Consolidated Income Statement. The business, which was part of our Applied Water segment, provided membrane filtration products primarily to customers in the municipal water and industrial sectors. The business reported 2016 annual revenue of approximately $8 million.

2016 Acquisitions and Divestitures

Sensus Worldwide Limited

On October 31, 2016, the Company acquired all of the outstanding equity interests of Sensus Worldwide Limited (other than Sensus Industries Limited) (“Sensus”) effective October 31, 2016 for $1,766 million ($1,710 million net of cash acquired), including a $6 million payment in 2017 for a working capital adjustment. Sensus develops advanced technology solutions that enable intelligent use and conservation of critical water and energy resources. Sensus' major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management.

Sensus results of operations were consolidated with the Company effective November 1, 2016 and along with our Analytics business it constitutes a separate reportable segment. Refer to Note 18 "Segment Information" for Measurement & Control Solutions segment information.

The Sensus purchase price allocation as of October 31, 2016 is shown in the following table.

(in millions)	Amount
Cash	$	56
Receivables	104
Inventories	79
Prepaid and other current assets	19
Property, plant and equipment	176
Intangible assets	782
Other long-term assets	5
Accounts payable	(69		)
Accrued and other current liabilities	(90		)
Deferred income tax liabilities	(198		)
Accrued post retirement benefits	(84		)
Other non-current accrued liabilities	(60		)
Total identifiable net assets	720
Goodwill	1,063
Non-controlling interest	(17		)
Total consideration	$	1,766

In the third quarter of 2017 we finalized the Sensus purchase price allocation. The fair values of Sensus assets and liabilities were determined based on estimates and assumptions which management believes are reasonable.

Goodwill arising from the acquisition consists largely of synergies and economies of scale expected from combining the operations of Sensus and Xylem. All of the goodwill was assigned to the Measurement & Control Solutions segment and is not deductible for tax purposes.

The estimate of the fair value of Sensus identifiable intangible assets was determined primarily using the “income approach,” which requires a forecast of all of the expected future cash flows either through the use of the multi-period excess earnings method or the relief-from-royalty method. Some of the more significant assumptions inherent in the development of intangible asset values include: the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows, the assessment of the intangible asset’s life cycle, as well as other factors. The following table summarizes key information underlying identifiable intangible assets related to the Sensus acquisition:

Category	Life	Amount (in millions)
Customer and Distributor Relationships	2 - 18 years	$	543
Tradenames	10 - 25 years	98
Internally Developed Network Software	7 years	60
FCC Licenses	Indefinite lived	24
Technology	5 - 15 years	39
Other	1 - 16 years	18
Total		$	782

The following table summarizes, on an unaudited pro forma basis, the condensed combined results of operations of the Company for the three and nine months ended September 30, 2016 assuming the acquisition of Sensus was made on January 1, 2015.

(in millions)	Three Months Ended September 30, 2016		Nine Months Ended September 30, 2016
Revenue	$	1,123	$	3,365
Net income	$	80	$	263

The foregoing unaudited pro forma results are for informational purposes only and are not necessarily indicative of the actual results of operations that might have occurred had the acquisition occurred on January 1, 2015, nor are they necessarily indicative of future results. The pro forma financial information includes the impact of purchase accounting and other nonrecurring items directly attributable to the acquisition, which include:

• Amortization expense of acquired intangibles

• Adjustments to the depreciation of property, plant and equipment reflecting the impact of the calculated fair value of those assets in accordance with purchase accounting

• Amortization of the fair value adjustment for warranty liabilities

• Adjustments to interest expense to remove historical Sensus interest costs and reflect Xylem's current debt profile

• The related tax impact of the above referenced adjustments

The pro forma results do not include any cost savings or operational synergies that may be generated or realized due to the acquisition of Sensus. The pro forma nine-month period reflects the inclusion of a $16 million tax valuation release and a $27 million reduction to warranty expense in the first calendar quarter of 2016.

Tideland Signal Corporation

On February 1, 2016, we acquired Tideland Signal Corporation (“Tideland”), a leading producer of analytics solutions in the coastal and ocean management sectors, for $70 million. Tideland, a privately-owned company headquartered in Texas, had approximately 160 employees. Our condensed consolidated financial statements include Tideland’s results of operations from February 1, 2016 within the Measurement & Control Solutions segment.

Restructuring Charges

Restructuring Charges

From time to time, the Company will incur costs related to restructuring actions in order to optimize our cost base and more strategically position ourselves based on the economic environment and customer demand. During the three and nine months ended September 30,2017, we recognized restructuring charges of $4 million and $17 million, respectively. We incurred these charges primarily as a continuation of our efforts to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water and Water Infrastructure segments, as well as headcount reductions within our Measurement & Control Solutions segment.

During the three and nine months ended September 30,2016, we recognized restructuring charges of $6 million and $18 million, respectively. We incurred these charges primarily in an effort to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water and Water Infrastructure segments, as well as Corporate headcount reductions.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Our quarterly provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items within periods presented. The comparison of our effective tax rate between periods is significantly impacted by the level and mix of earnings and losses by tax jurisdiction, foreign income tax rate differentials and discrete items.

The income tax provision for the three months ended September 30, 2017 was $27 million resulting in an effective tax rate of 21.1%, compared to $22 million resulting in an effective tax rate of 22.9% for the same period in 2016. The income tax provision for the nine months ended September 30, 2017 was $62 million resulting in an effective tax rate of 19.4%, compared to $40 million resulting in an effective tax rate of 16.0% for the same period in 2016. The effective tax rate was lower than the United States federal statutory rate primarily due to the mix of earnings in jurisdictions in both periods. Additionally, the effective tax rate for the nine months ended September 30, 2016 was lower than the current period due to the release of an unrecognized tax benefit in 2016 due to the effective settlement of a tax examination, partially offset by the nonrecurring repatriation of foreign earnings from 2016.

Unrecognized Tax Benefits

We recognize tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the condensed consolidated financial statements from such positions are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

The amount of unrecognized tax benefits at September 30, 2017 was $75 million, as compared to $67 million at December 31, 2016, which if ultimately recognized will reduce our effective tax rate. We do not believe that the unrecognized tax benefits will significantly change within the next twelve months.

We classify interest expense relating to unrecognized tax benefits as a component of other non-operating expense, net, and tax penalties as a component of income tax expense in our Condensed Consolidated Income Statements. As of September 30, 2017, we had $3.6 million of interest accrued for unrecognized tax benefits.

(a) Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

(b) Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 14, "Share-Based Compensation Plans" to the condensed consolidated financial statements for further detail on the performance share units.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions, and principally manage our exposures to these risks through management of our core business activities. Certain of our foreign operations expose us to fluctuations of foreign interest rates and exchange rates that may impact revenue, expenses, cash receipts, cash payments, and the value of our stockholders' equity. We enter into derivative financial instruments to protect the value or fix the amount of certain cash flows in terms of the functional currency of the business unit with that exposure and reduce the volatility in stockholders' equity.

Cash Flow Hedges of Foreign Exchange Risk

We are exposed to fluctuations in various foreign currencies against our functional currencies. We use foreign currency derivatives, including currency forward agreements, to manage our exposure to fluctuations in the various exchange rates. Currency forward agreements involve fixing the foreign currency exchange rate for delivery of a specified amount of foreign currency on a specified date.

Certain business units with exposure to foreign currency exchange risks have designated certain currency forward agreements as cash flow hedges of forecasted intercompany inventory purchases and sales. Our principal currency exposures relate to the Euro, Swedish Krona, British Pound, Canadian Dollar, Polish Zloty Australian Dollar and Hungarian Forint. We had foreign exchange contracts with purchase notional amounts totaling $58 million as of September 30, 2017. As of September 30, 2017, our most significant foreign currency derivatives included contracts to purchase Swedish Krona and sell Euro, sell U.S. Dollar and purchase Euro, sell British Pound and purchase Euro, and to purchase Polish Zloty and sell Euro. The purchased notional amounts associated with these currency derivatives are $26 million, $9 million, $8 million, and $7 million, respectively. As of December 31, 2016 we did not hold any foreign exchange contracts.

Hedges of Net Investments in Foreign Operations

We are exposed to changes in foreign currencies impacting our net investments held in foreign subsidiaries.

Cross Currency Swaps

Beginning in 2015, we entered into cross currency swaps to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. The total notional amount of derivative instruments designated as net investment hedges was $440 million and $391 million as of September 30, 2017 and December 31, 2016, respectively.

Foreign Currency Denominated Debt

On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023. We designated the entirety of the outstanding balance, or $583 million, net of unamortized discount, as a hedge of a net investment in certain foreign subsidiaries.

The table below presents the effect of our derivative financial instruments on the Condensed Consolidated Income Statements and Statements of Comprehensive Income.

(a) Effective portion

As of September 30, 2017, $3 million of net gains on cash flow hedges are expected to be reclassified into earnings in the next 12 months. The ineffective portion of a cash flow hedge is recognized immediately in selling, general and administrative expenses in the Condensed Consolidated Income Statements and was not material for the three and nine months ended September 30,2017 and 2016.

As of September 30, 2017, no gains or losses on the net investment hedges are expected to be reclassified into earnings over their duration. The net investment hedges did not experience any ineffectiveness for the three and nine months ended September 30,2017.

The fair values of our derivative assets and liabilities are measured on a recurring basis using Level 2 inputs and are determined through the use of models th at consider various assumptions including yield curves, time value and other measurements.

The fair values of our foreign exchange contracts currently included in our hedging program designated as hedging instruments were as follows:

(b) The debt issuance costs and unamortized discount are recognized as a reduction in the carrying value of the Senior Notes in the Condensed Consolidated Balance Sheets and are being amortized to interest expense in our Condensed Consolidated Income Statements over the expected remaining terms of the Senior Notes.

Senior Notes

On September 20, 2011, we issued 3.550% Senior Notes of $600 million aggregate principal amount due September 2016 (the "Senior Notes due 2016") and 4.875% Senior Notes of $600 million aggregate principal amount due October 2021 (the "Senior Notes due 2021"). On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023 (the "Senior Notes due 2023"). On October 11, 2016, we issued 3.250% Senior Notes of $500 million aggregate principal amount due October 2026 (the “Senior Notes due 2026”) and 4.375% Senior Notes of $400 million aggregate principal amount due October 2046 (the “Senior Notes due 2046” and, together with the Senior Notes due 2021, the Senior Notes due 2023 and the Senior Notes due 2026, the “Senior Notes”).

The Senior Notes include covenants that restrict our ability, subject to exceptions, to incur debt secured by liens and engage in sale and leaseback transactions, as well as provide for customary events of default (subject, in certain cases, to receipt of notice of default and/or customary grace and cure periods). We may redeem the Senior Notes, as applicable, in whole or in part, at any time at a redemption price equal to the principal amount of the Senior Notes to be redeemed, plus a make-whole premium. We may also redeem the Senior Notes in certain other circumstances, as set forth in the applicable Senior Notes indenture.

If a change of control triggering event (as defined in the applicable Senior Notes indenture) occurs, we will be required to make an offer to purchase the Senior Notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to the date of repurchase.

Interest on the Senior Notes due 2021 is payable on April 1 and October 1 of each year. Interest on the Senior Notes due 2023 is payable on March 11 of each year. Interest on the Senior Notes due 2026 and the Senior Notes due 2046 is payable on May 1 and November 1 of each year beginning on May 1, 2017. As of September 30, 2017, we were in compliance with all covenants for the Senior Notes.

We used the net proceeds of the Senior Notes due 2026 and the Senior Notes due 2046, together with cash on hand, proceeds from issuances under our existing commercial paper program and borrowings under the Term Facility (as described below), to fund the acquisition of Sensus (refer to Note 3 for further information on the Sensus acquisition).

Credit Facilities

Five-Year Revolving Credit Facility

Effective March 27, 2015, Xylem entered into a Five-Year Revolving Credit Facility (the "Credit Facility") with Citibank, N.A., as administrative agent, and a syndicate of lenders. The Credit Facility provides for an aggregate principal amount of up to $600 million of: (i) revolving extensions of credit (the "revolving loans") outstanding at any time and (ii) the issuance of letters of credit in a face amount not in excess of $100 million outstanding at any time. The Credit Facility provides for increases of up to $200 million for a possible maximum total of $800 million in aggregate principal amount at our request and with the consent of the institutions providing such increased commitments.

At our election, the interest rate per annum applicable to the revolving loans will be based on either (i) a Eurodollar rate determined by reference to LIBOR, adjusted for statutory reserve requirements, plus an applicable margin or (ii) a fluctuating rate of interest determined by reference to the greatest of: (a) the prime rate of Citibank, N.A., (b) the U.S. Federal funds effective rate plus half of 1% or (c) the Eurodollar rate determined by reference to LIBOR, adjusted for statutory reserve requirements, in each case, plus an applicable margin.

In accordance with the terms of an amendment to the Credit Facility dated August 30, 2016, we may not exceed a maximum leverage ratio of 4.00 to 1.00 (based on a ratio of total debt to earnings before interest, taxes, depreciation and amortization) for a period of four full fiscal quarters following the Sensus acquisition and a maximum leverage ratio of 3.50 to 1.00 through the rest of the term. The Credit Facility also contains limitations on, among other things, incurring secured debt, granting liens, entering into sale and leaseback transactions, mergers, consolidations, liquidations, dissolutions and sales of assets. In addition, the Credit Facility contains other terms and conditions such as customary representations and warranties, additional covenants and customary events of default. As of September 30, 2017 the Credit Facility was undrawn and we are in compliance with all covenants.

European Investment Bank - R&D Finance Contract

On October 28, 2016, the Company entered into a Finance Contract (the “Finance Contract”) with the European Investment Bank (the “EIB”). The Company's wholly owned subsidiaries in Luxembourg, Xylem Holdings S.á r.l. and Xylem International S.á r.l., are the borrowers under the Finance Contract and Xylem Inc. is the Guarantor.  The Finance Contract provides for up to €105 million (approximately $124 million) to finance research, development and innovation projects in the field of sustainable water and wastewater solutions during the period from 2017 through 2019 in Sweden, Germany, Italy, UK, Hungary and Austria. The Company has unconditionally guaranteed the performance of the borrowers under the Finance Contract.Under the Finance Contract, the borrowers are able to draw loans on or before April 28, 2018, with a maturity of no longer than 11 years.

Both the Finance Contract and the R&D Facility Agreement (described below) are subject to the same leverage ratio as the Credit Facility. Both agreements also contain limitations on, among other things, incurring debt, granting liens, and entering into sale and leaseback transactions, as well as other terms and conditions, such as customary representations and warranties, additional covenants and customary events of default.

Both the Finance Contract and the R&D Facility Agreement provide for fixed rate loans and floating rate loans. Under the Finance Contract, the interest rate per annum applicable to fixed rate loans is at a fixed percentage rate per annum specified by the EIB which includes the applicable margin. The interest rate per annum applicable to floating rate loans is at the rate determined by reference to EURIBOR for loans drawn in Euros and LIBOR for loans drawn in Pounds Sterling or U.S. Dollars, plus an applicable spread specified by the EIB which includes the applicable margin. The applicable margin is 59 basis points (0.59%). As of September 30, 2017 and December 31, 2016, $124 million and $110 million were outstanding under the Finance Contract, respectively.

European Investment Bank - R&D Facility Agreement

On December 3, 2015, the Company amended and restated its Risk Sharing Finance Facility Agreement (the "R&D Facility Agreement") with the EIB to amend the maturity date. The Facility provides an aggregate principal amount of up to €120 million (approximately $141 million) to finance research projects and infrastructure development in the European Union. The Company's wholly owned subsidiaries in Luxembourg, Xylem Holdings S.á r.l. and Xylem International S.á r.l., are the borrowers under the R&D Facility Agreement. The obligations of the borrowers under the R&D Facility Agreement are guaranteed by the Company under an Amended and Restated Deed of Guarantee, dated as of December 4, 2013, in favor of the EIB.

Under the R&D Facility Agreement, the borrower was able to draw loans on or before March 31, 2016 with a maturity of no longer than 12 years. As of September 30, 2017 and December 31, 2016 $43 million and $38 million were outstanding, respectively, under the R&D Facility Agreement. Although the borrowing term for this arrangement is up to five years, we have classified it as short-term debt on our Consolidated Balance Sheets since we intend to repay this obligation in less than a year.

Term Loan Facility

On October 24, 2016, the Company’s subsidiary, Xylem Europe GmbH (the “borrower”) entered into a 12-month €150 million (approximately $177 million) term loan facility (the “Term Facility”) the terms of which are set forth in a term loan agreement, among the borrower, the Company, as parent guarantor and ING Bank.  The Company has entered into a parent guarantee in favor of ING Bank also dated October 24, 2016 to secure all present and future obligations of the borrower under the Term Loan Agreement.  The Term Facility was used to partially fund the acquisition of Sensus. The Term Facility will mature on October 26, 2017. The Term Facility bears interest at EURIBOR plus 0.35%. The agreement contains certain representations and warranties, certain affirmative covenants, certain negative covenants, a financial covenant, certain conditions and events of default that are customarily required for similar financings. As of September 30, 2017 and December 31, 2016, $24 million and $157 million were outstanding under the Term Loan Facility, respectively.

Commercial Paper

Our commercial paper program generally serves as a means of short-term funding and has a combined outstanding limit of $600 million inclusive of the Five-Year Revolving Credit Facility. As of September 30, 2017 and December 31, 2016 $30 million and $65 million of the Company’s $600 million commercial paper program was outstanding at a weighted average interest rate of 1.44% and 1.12%, respectively. We will periodically borrow under this program and may borrow under it in future periods.

Share-based compensation expense was $5 million and $16 million during the three and nine months ended September 30, 2017, respectively, and $5 million and $15 million during the three and nine months ended September 30,2016, respectively. The unrecognized compensation expense related to our stock options, restricted stock units and performance share units was $7 million, $21 million and $14 million, respectively, at September 30, 2017 and is expected to be recognized over a weighted average period of 1.9, 2.0 and 2.0 years, respectively. The amount of cash received from the exercise of stock options was $8 million and $22 million for the nine months endedSeptember 30, 2017 and 2016, respectively.

Stock Option Grants

The following is a summary of the changes in outstanding stock options for the nine months ended September 30, 2017.

	Share units            (in thousands)		Weighted Average Exercise Price / Share		Weighted  Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2017	2,126		$	33.71	6.9
Granted	501		48.43
Exercised	(257	)	31.87
Forfeited and expired	(50	)	42.08
Outstanding at September 30, 2017	2,320		$	36.91	7.0	$	60
Options exercisable at September 30, 2017	1,383		$	32.89	5.8	$	41
Vested and expected to vest as of September 30, 2017	2,219		$	35.87	6.8	$	58

The total intrinsic value of options exercised (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) during the nine months ended September 30, 2017 was $5.5 million.

Stock Option Fair Value

The fair value of each option grant was estimated on the date of grant using the binomial lattice pricing model which incorporates multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The following are weighted-average assumptions for 2017 grants.

Volatility	25.40		%
Risk-free interest rate	2.07		%
Dividend yield	1.49		%
Expected term (in years)	5.1
Weighted-average fair value / share	$	10.66

Expected volatility is calculated based on a weighted analysis of historic and implied volatility measures for a set of peer companies and Xylem. We use historical data to estimate option exercise and employee termination behavior within the valuation model. Employee groups and option characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time options are expected to remain outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of option grant.

Restricted Stock Unit Grants

The following is a summary of restricted stock unit activity for the nine months ended September 30, 2017. The fair value of the restricted stock units is equal to the closing share price on the date of the grant. 

	Share units (in thousands)		Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2017	899		$	37.67
Granted	344		49.69
Vested	(357	)	38.24
Forfeited	(60	)	40.78
Outstanding at September 30, 2017	826		$	35.53

ROIC Performance Share Unit Grants

The following is a summary of Return on Invested Capital ("ROIC") performance share unit grants for the nine months ended September 30, 2017. The fair value of the ROIC performance share units is equal to the closing share price on the date of the grant. 

	Share units (in thousands)		Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2017	250		$	37.11
Granted	117		49.15
Vested	—		—
Forfeited	(68	)	38.44
Outstanding at September 30, 2017	299		$	41.50

TSR Performance Share Units Grants

The following is a summary of our Total Shareholder Return ("TSR") performance share unit grants for the nine months ended September 30, 2017.

	Share units (in thousands)		Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2017	108		$	46.15
Granted	117		47.79
Vested	—		—
Forfeited	(11	)	43.98
Outstanding at September 30, 2017	214		$	47.03

The fair value of TSR performance share units was calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The following are weighted-average assumptions for 2017 grants.

Volatility	30.2	%

Commitments and Contingencies

Commitments and Contingencies

Legal Proceedings

From time to time, we are involved in legal proceedings that are incidental to the operation of our businesses, including acquisitions and divestitures, intellectual property matters, product liability and personal injury claims, employment and pension matters, government and commercial contract disputes.

From time to time claims may be asserted against Xylem alleging injury caused by any of our products resulting from asbestos exposure. We believe there are numerous legal defenses available for such claims and would defend ourselves vigorously. Pursuant to the Distribution Agreement among ITT Corporation (now ITT LLC), Exelis and Xylem, ITT Corporation (now ITT LLC) has an obligation to indemnify, defend and hold Xylem harmless for asbestos product liability matters, including settlements, judgments, and legal defense costs associated with all pending and future claims that may arise from past sales of ITT’s legacy products. We believe ITT Corporation (now ITT LLC) remains a substantial entity with sufficient financial resources to honor its obligations to us.

Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claims, we do not expect that any asserted or unasserted legal claims or proceedings, individually or in aggregate, will have a material adverse effect on our results of operations, or financial condition. We have estimated and accrued $10 million and $11 million as of September 30, 2017 and December 31, 2016, respectively, for these general litigation matters.

Indemnifications

As part of our 2011 spin-off from our former parent, ITT Corporation (now ITT LLC), Exelis Inc. and Xylem will indemnify, defend and hold harmless each of the other parties with respect to such parties’ assumed or retained liabilities under the Distribution Agreement and breaches of the Distribution Agreement or related spin agreements. The former parent’s indemnification obligations include asserted and unasserted asbestos and silica liability claims that relate to the presence or alleged presence of asbestos or silica in products manufactured, repaired or sold prior to October 31, 2011, the Distribution Date, subject to limited exceptions with respect to certain employee claims, or in the structure or material of any building or facility, subject to exceptions with respect to employee claims relating to Xylem buildings or facilities. The indemnification associated with pending and future asbestos claims does not expire. Xylem has not recorded a liability for material matters for which we expect to be indemnified by the former parent or Exelis Inc. through the Distribution Agreement and we are not aware of any claims or other circumstances that would give rise to material payments from us under such indemnifications. On May 29, 2015, Harris Inc. acquired Exelis.  As the parent of Exelis, Harris Inc. is responsible for Exelis’s indemnification obligations under the Distribution Agreement.

Guarantees

We obtain certain stand-by letters of credit, bank guarantees and surety bonds from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance related requirements. As of September 30, 2017 and December 31, 2016, the amount of stand-by letters of credit, bank guarantees and surety bonds was $235 million and $218 million, respectively.

Environmental

In the ordinary course of business, we are subject to federal, state, local, and foreign environmental laws and regulations. We are responsible, or are alleged to be responsible, for ongoing environmental investigation and remediation of sites in various countries. These sites are in various stages of investigation and/or remediation and in many of these proceedings our liability is considered de minimis. We have received notification from the U.S. Environmental Protection Agency, and from similar state and foreign environmental agencies, that a number of sites formerly or currently owned and/or operated by Xylem or for which we are responsible under the Distribution Agreement, and other properties or water supplies that may be or have been impacted from those operations, contain disposed or recycled materials or wastes and require environmental investigation and/or remediation. These sites include instances where we have been identified as a potentially responsible party under federal and state environmental laws and regulations.

Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Our accrued liabilities for these environmental matters represent the best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees. These estimates, and related accruals, are reviewed quarterly and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. Liabilities for these environmental expenditures are recorded on an undiscounted basis. We have estimated and accrued $4 million and $4 million as of September 30, 2017 and December 31, 2016, respectively, for environmental matters.

It is difficult to estimate the final costs of investigation and remediation due to various factors, including incomplete information regarding particular sites and other potentially responsible parties, uncertainty regarding the extent of investigation or remediation and our share, if any, of liability for such conditions, the selection of alternative remedial approaches, and changes in environmental standards and regulatory requirements. We believe the total amount accrued is reasonable based on existing facts and circumstances.

Warranties

We warrant numerous products, the terms of which vary widely. In general, we warrant products against defect and specific non-performance. The table below provides the changes in our product warranty accrual, which for 2017 includes warranty related to the Sensus acquisition.

(in millions)	2017			2016

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated.

The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair presentation of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2016 ("2016 Annual Report") in preparing these unaudited condensed consolidated financial statements, with the exception of accounting standard updates described in Note 2. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2016 Annual Report.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, postretirement obligations and assets, revenue recognition, income tax contingency accruals and valuation allowances, goodwill and indefinite lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates.

Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.

Recently Issued Accounting Pronouncements (Policies)

Accounting Policies [Abstract]

Pronouncements Not Yet Adopted and Recently Adopted Pronouncements

Pronouncements Not Yet Adopted

In August 2017, the Financial Accounting Standards Board (“FASB”) issued amended guidance on hedging activities. The amendment better aligns a company’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying for hedging relationships and the presentation of hedge results. Specifically, the guidance:

(1)Eliminates the concept of recognizing periodic hedge ineffectiveness for cash flow and net investment hedges

(2)Eliminates the benchmark interest rate concept of variable - rate instruments in cash flow hedges and allows companies to designate the contractually specified interest rate as the hedged risk

(3)Requires a company to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported

(4)Provides the ability to perform subsequent hedge effectiveness tests qualitatively

This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted with the effect of adoption reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing at the date of adoption, a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness is required. Other presentation and disclosure guidance is required only prospectively. We are evaluating the impact of the guidance on our financial condition and results of operations.

In March 2017, the FASB issued amended guidance on presentation of net periodic benefit costs.  The amendment requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period.  The other components are required to be presented in the income statement separately and outside a subtotal of income from operations, if one is presented.  The amendment also requires entities to disclose the income statement lines that contain the other components if they are not appropriately described.  This guidance is effective retrospectively for periods beginning after December 15, 2017, including interim periods within those annual periods.  Early adoption is permitted.  The adoption of this guidance is expected to impact the presentation between operating income and other non operating income within Xylem's Consolidated Income Statement but is not expected to have a material impact on our consolidated financial condition or results of operations.

In June 2016, the FASB issued guidance amending the accounting for the impairment of financial instruments, including trade receivables. Under current guidance, credit losses are recognized when the applicable losses are probable of occurring and this assessment is based on past events and current conditions. The amended guidance eliminates the “probable” threshold and requires an entity to use a broader range of information, including forecast information when estimating expected credit losses. Generally, this should result in a more timely recognition of credit losses. This guidance is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted for interim and annual periods beginning after December 15, 2018. The requirements of the amended guidance should be applied using a modified retrospective approach except for debt securities, which require a prospective transition approach. We are evaluating the impact of the guidance on our financial condition and results of operations.

In February 2016, the FASB issued guidance amending the accounting for leases. Specifically, the amended guidance requires all lessees to record a lease liability at lease inception, with a corresponding right of use asset, except for short-term leases. Lessor accounting is not fundamentally changed. This amended guidance is effective for interim and annual periods beginning after December 15, 2018 using a modified retrospective approach. Early adoption is permitted. We are evaluating the impact of the guidance on our financial condition and results of operations.

In May 2014, the FASB issued guidance on recognizing revenue from contracts with customers. The guidance outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the model is that an entity recognizes revenue to portray the transfer of goods and 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. The standard also expands disclosure requirements regarding revenue recognition. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017 and may be applied retrospectively to each prior period presented or using a modified retrospective approach with the cumulative effect recognized as of the date of initial application. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2016. The impact of this guidance on our financial condition and results of operations will be based on the types of contracts that Xylem is awarded in the future. We currently do not believe that the adoption of this guidance will have a material impact on our financial statements and plan to adopt this guidance effective January 1, 2018 using the modified retrospective approach.

Recently Adopted Pronouncements

In May 2017, the FASB issued guidance, which amends the scope of modification accounting guidance for share-based payment arrangements. The guidance outlines the types of changes to the terms or conditions of share-based payment arrangements that would require the use of modification accounting. Specifically, modification accounting would not apply if the fair value, vesting conditions, and classification of the award as equity or liability are the same immediately before and after the modification. This guidance is effective prospectively for interim and annual reporting periods beginning December 15, 2017 and early adoption is permitted. We elected to early adopt this guidance effective the second quarter of 2017. The adoption of this guidance did not impact our financial condition or results from operations.

In January 2017, the FASB issued guidance amending the impairment testing of goodwill. Under current guidance, the testing of goodwill for impairment is performed at least annually using a two-step test. Step one involves comparing the fair value of a “reporting unit” to its carrying amount. If the applicable book value exceeds the reporting unit’s fair value then step two must be performed. Step two involves comparing the fair value of the reporting unit’s goodwill to the applicable carrying amount of the asset and recognizing an impairment charge equal to the amount by which the carrying amount of the goodwill exceeds its implied fair value. The amended guidance eliminates step two of the impairment test and allows an entity to record an impairment charge equal to the amount that the carrying amount of the applicable reporting unit exceeds its fair value, up to the value of the recorded goodwill. This guidance is effective prospectively for interim and annual goodwill impairment tests beginning after December 15, 2019 with early adoption permitted for interim or annual tests after January 1, 2017. We elected to early adopt this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

In October 2016, the FASB issued guidance amending the accounting for income taxes. Under current guidance the recognition of current and deferred income taxes for an intra-entity asset transfer is prohibited until the asset has been sold to an outside party. The amended guidance eliminates the prohibition against immediate recognition of current and deferred income tax amounts associated with intra-entity transfers of assets other than inventory. This guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. The requirements of the amended guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We elected to early adopt this guidance effective the first quarter of 2017. As a result of adopting the amended guidance, prepaid tax assets were reduced by $14 million, long-term deferred tax assets increased $3 million, and accrued taxes were reduced by $4 million. The net impact of these adjustments on retained earnings was a decrease of $7 million.

In July 2015, the FASB issued guidance regarding simplifying the measurement of inventory. Under prior guidance, inventory is measured at the lower of cost or market, where market is defined as replacement cost, with a ceiling of net realizable value and a floor of net realizable value less a normal profit margin. The amended guidance requires the measurement of inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective prospectively for interim and annual periods beginning after December 15, 2016 and early application is permitted. We adopted this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

(a) Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

(b) Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 14, "Share-Based Compensation Plans" to the condensed consolidated financial statements for further detail on the performance share units.

[1] Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

[2] Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 14, "Share-Based Compensation Plans" to the condensed consolidated financial statements for further detail on the performance share units.
