NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2019

(UNAUDITED)

In this Quarterly Report on Form 10-Q, the terms "we," "us," "our," "Itron," and the "Company" refer to Itron, Inc.

Note 1:    Summary of Significant Accounting Policies

Financial Statement Preparation

The condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q are unaudited and reflect entries necessary for the fair presentation of the Consolidated Statements of Operations, the Consolidated Statements of Comprehensive Income (Loss), Consolidated Statements of Equity, and Consolidated Statements of Cash Flows for the three and six months ended June 30, 2019 and 2018, and the Consolidated Balance Sheets as of June 30, 2019 and December 31, 2018, of Itron, Inc. and its subsidiaries. All entries required for the fair presentation of the financial statements are of a normal recurring nature, except as disclosed. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the full year or for any other period.

Certain information and notes normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim results. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2018 filed with the SEC in our Annual Report on Form 10-K on February 28, 2019 (2018 Annual Report). There have been no significant changes in financial statement preparation or significant accounting policies since December 31, 2018 other than the adoption of Accounting Standards Codification (ASC) 842, Leases.

Restricted Cash and Cash Equivalents

Cash and cash equivalents that are contractually restricted from operating use are classified as restricted cash and cash equivalents.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows:

In thousands	June 30, 2019		December 31, 2018		June 30, 2018
Cash and cash equivalents	$	135,736	$	120,221	$	162,882
Restricted cash included in other current assets	51		51		51
Long-term restricted cash	2,066		2,056		2,109
Total cash, cash equivalents, and restricted cash	$	137,853	$	122,328	$	165,042

Subsequent to the issuance of our June 30, 2018 consolidated financial statements, we determined $150 million of proceeds from borrowings and payments on debt, originally transacted during the first quarter of 2018, had been improperly netted within the financing activities section of the Consolidated Statements of Cash Flows for the first three quarters of 2018. We corrected this presentation for the 2018 Annual Report on Form 10‑K. The accompanying Consolidated Statement of Cash Flows for the six months ended June 30, 2018 has been revised from amounts previously reported to separately present the $150 million of proceeds from borrowings and the payments on debt. We assessed the significance of the misstatement and concluded that it was not material to any prior periods. There were no changes to net cash flows from operating, investing, or financing activities as a result of this change.

Leases

We determine if an arrangement is a lease at inception. A lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment), and (2) the customer has the right to control the use of the identified asset.

Operating leases are included in operating lease right-of-use ("ROU") assets, other current liabilities, and operating lease liabilities on our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, other current liabilities, and other long-term obligations on our Consolidated Balance Sheets.

7

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit rate when readily determinable. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Operating lease ROU asset also includes any lease payments made and excludes lease incentives received and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements, which include lease and nonlease components. For each of our existing asset classes, we have elected the practical expedient to account for the lease and nonlease components as a single lease component when the nonlease components are fixed.

We have not elected to utilize the short-term lease exemption for any leased asset class. All leases with a lease term that is greater than one month will be subject to recognition and measurement on the balance sheet.

Lease expense for variable lease payments, where the timing or amount of the payment is not fixed, are recognized when the obligation is incurred. Variable lease payments generally arise in our net lease arrangements where executory and other lease-related costs are billed to Itron when incurred by the lessor.

Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) (ASU 2016-02), which required substantially all leases be recognized by lessees on their balance sheet as a right-of-use asset and corresponding lease liability, including leases previously accounted for as operating leases. The new standard also resulted in enhanced quantitative and qualitative disclosures, including significant judgments made by management, to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing leases. The standard required modified retrospective adoption and was effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. We adopted ASC 842, as amended, on January 1, 2019, and it resulted in an increase to operating lease right-of-use assets, other current liabilities, and operating lease liabilities of $74.6 million, $14.5 million, and $61.5 million, respectively, and a decrease in other current assets and other long-term obligations of $1.5 million and $2.9 million, respectively.

In August 2018, the FASB issued ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments also require us to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. We adopted ASU 2018-15 as of January 1, 2019, and it did not have a material impact on our financial condition, results of operations, or cash flows.

In October 2018, the FASB issued ASU 2018-16, Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. We adopted this standard on January 1, 2019, and it did not materially impact our consolidated financial statements. This update establishes OIS rates based on SOFR as an approved benchmark interest rate in addition to existing rates such as the LIBOR swap rate.

Recent Accounting Standards Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) (ASU 2016-13), which replaces the incurred loss impairment methodology in current GAAP with a methodology based on expected credit losses. This estimate of expected credit losses uses a broader range of reasonable and supportable information. This change will result in earlier recognition of credit losses. ASU 2016-13, as amended, will be effective as of January 1, 2020 for us. We are currently evaluating the impact of this standard on our consolidated financial statements, as well as our accounting policies, processes, and systems.

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), which amends the disclosure requirements under ASC 820, Fair Value Measurements. ASU 2018-13 is effective for us beginning with our interim financial reports for the first quarter of 2020. We are currently evaluating the impact

this standard will have on our consolidated financial statement disclosures related to assets and liabilities subject to fair value measurement.

In August 2018, the FASB issued ASU 2018-14, Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14), which amends the disclosure requirements under ASC 715-20, Compensation-Retirement Benefits-Defined Benefit Plans. ASU 2018-14 is effective for our financial reporting in 2020. We are currently evaluating the impact this standard will have on our financial statement disclosures for our defined benefit plans.

Note 2:    Earnings Per Share

Net income (loss) per common share - Diluted	$	0.49	$	0.07	$	0.44	$	(3.66	)

Stock-based Awards

For stock-based awards, the dilutive effect is calculated using the treasury stock method. Under this method, the dilutive effect is computed as if the awards were exercised at the beginning of the period (or at time of issuance, if later) and assumes the related proceeds were used to repurchase common stock at the average market price during the period. Related proceeds include the amount the employee must pay upon exercise and the future compensation cost associated with the stock award. Approximately 0.5 million and 0.6 million stock-based awards were excluded from the calculation of diluted EPS for the three and six months ended June 30, 2019 because they were anti-dilutive. Approximately 0.7 million and 1.1 million stock-based awards were excluded from the calculation of diluted EPS for the three and six months ended June 30, 2018 because they were anti-dilutive. These stock-based awards could be dilutive in future periods.

On January 5, 2018, we completed our acquisition of Silver Spring Networks, Inc. (SSNI) by purchasing 100% of the voting stock. Acquired intangible assets include in-process research and development (IPR&D), which is not amortized until such time as the associated development projects are completed. Of these projects, $3.1 million were completed during the first half of 2019 and are included in core-developed technology. Acquired intangible liabilities reflect the present value of the projected cash outflows for an existing contract where remaining costs are expected to exceed projected revenues.

Silver Spring Networks, Inc. Acquisition

On January 5, 2018, we completed the acquisition of SSNI by purchasing 100% of SSNI's outstanding stock. The acquisition was financed through incremental borrowings and cash on hand. Refer to "Note 6: Debt" for further discussion of our debt. SSNI provided smart network and data platform solutions for electricity, gas, water and smart cities including advanced metering, distribution automation, demand-side management, and street lights.

The fair values for the identified trademarks and core-developed technology intangible assets were estimated using the relief from royalty method. The fair value of customer contract and relationship were estimated using the income approach. The IPR&D was valued utilizing the replacement cost method. These consolidated financial statements should be read in conjunction with the audited financial statements and notes included in our 2018 Annual Report.

The purchase price of SSNI was $809.2 million, which is net of $97.8 million of acquired cash and cash equivalents. Of the total consideration, $802.5 million was paid in cash. The remaining $6.7 million relates to the fair value of pre-acquisition service for replacement awards of unvested SSNI options and restricted stock unit awards with an Itron equivalent award. We allocated the purchase price to the assets acquired and liabilities assumed based on estimated fair value assessments. During the three months ended March 31, 2019, we recognized additional contract assets totaling $8.0 million and additional deferred tax liabilities of $2.0 million, for a net reduction in goodwill of $6.0 million. As of the first quarter of 2019, the measurement period for the acquisition of SSNI was complete, and any further adjustments to assets acquired or liabilities assumed are recognized through the Consolidated Statement of Operations.

Credit Facility

On January 5, 2018, we entered into a credit agreement providing for committed credit facilities in the amount of $1.2 billion U.S. dollars (the 2018 credit facility), which amended and restated in its entirety our credit agreement dated June 23, 2015 and replaced committed facilities in the amount of $725 million. The 2018 credit facility consists of a $650 million U.S. dollar term loan (the term loan) and a multicurrency revolving line of credit (the revolver) with a principal amount of up to $500 million. The revolver also contains a $300 million standby letter of credit sub-facility and a $50 million swingline sub-facility. Both the term loan and the revolver mature on January 5, 2023 and can be repaid without penalty. Amounts repaid on the term loan may not be reborrowed and amounts borrowed under the revolver may be repaid and reborrowed until the revolver's maturity, at which time all outstanding loans together with all accrued and unpaid interest must be repaid. Amounts not borrowed under the revolver are subject to a commitment fee, which is paid in arrears on the last day of each fiscal quarter, ranging from 0.18% to 0.35% per annum depending on our total leverage ratio as of the most recently ended fiscal quarter.

The 2018 credit facility permits us and certain of our foreign subsidiaries to borrow in U.S. dollars, euros, British pounds, or, with lender approval, other currencies readily convertible into U.S. dollars. All obligations under the 2018 credit facility are guaranteed by Itron, Inc. and material U.S. domestic subsidiaries and are secured by a pledge of substantially all of the assets of Itron, Inc. and material U.S. domestic subsidiaries, including a pledge of their related assets. This includes a pledge of 100% of the capital stock of material U.S. domestic subsidiaries and up to 66% of the voting stock (100% of the non-voting stock) of first-tier foreign subsidiaries. In addition, the obligations of any foreign subsidiary who is a foreign borrower, as defined by the 2018 credit facility, are guaranteed by the foreign subsidiary and by its direct and indirect foreign parents. The 2018 credit facility includes debt covenants, which contain certain financial thresholds and place certain restrictions on the incurrence of debt, investments, and the issuance of dividends. We were in compliance with the debt covenants under the 2018 credit facility at June 30, 2019.

12

Under the 2018 credit facility, we elect applicable market interest rates for both the term loan and any outstanding revolving loans. We also pay an applicable margin, which is based on our total leverage ratio as defined in the credit agreement. The applicable rates per annum may be based on either: (1) the LIBOR rate or EURIBOR rate (subject to a floor of 0%), plus an applicable margin, or (2) the Alternate Base Rate, plus an applicable margin. The Alternate Base Rate election is equal to the greatest of three rates: (i) the prime rate, (ii) the Federal Reserve effective rate plus 0.50%, or (iii) one-month LIBOR plus 1.00%. At June 30, 2019, the interest rate for both the term loan and revolver was 4.16%, which includes the LIBOR rate plus a margin of 1.75%.

Senior Notes

On December 22, 2017 and January 19, 2018, we issued $300 million and $100 million, respectively, of aggregate principal amount of 5.00% senior notes maturing January 15, 2026 (Notes). The proceeds were used to refinance existing indebtedness related to the acquisition of SSNI, pay related fees and expenses, and for general corporate purposes. Interest on the Notes is payable semi-annually in arrears on January 15 and July 15, commencing on July 15, 2018. The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our subsidiaries that guarantee the 2018 credit facility.

Prior to maturity we may redeem some or all of the Notes, together with accrued and unpaid interest, if any, plus a "make-whole" premium. On or after January 15, 2021, we may redeem some or all of the Notes at any time at declining redemption prices equal to 102.50% beginning on January 15, 2021, 101.25% beginning on January 15, 2022 and 100.00% beginning on January 15, 2023 and thereafter to the applicable redemption date. In addition, before January 15, 2021, and subject to certain conditions, we may redeem up to 35% of the aggregate principal amount of Notes with the net proceeds of certain equity offerings at 105.00% of the principal amount thereof to the date of redemption; provided that (i) at least 65% of the aggregate principal amount of Notes remains outstanding after such redemption and (ii) the redemption occurs within 60 days of the closing of any such equity offering.

Debt Maturities

The amount of required minimum principal payments on our long-term debt in aggregate over the next five years, are as follows:

Note 7:    Derivative Financial Instruments

As part of our risk management strategy, we use derivative instruments to hedge certain foreign currency and interest rate exposures. Refer to "Note 13: Shareholder's Equity" and "Note 14: Fair Values of Financial Instruments" for additional disclosures on our derivative instruments.

The fair values of our derivative instruments are determined using the income approach and significant other observable inputs (also known as "Level 2"). We have used observable market inputs based on the type of derivative and the nature of the underlying instrument. The key inputs include interest rate yield curves (swap rates and futures) and foreign exchange spot and forward rates, all of which are available in an active market. We have utilized the mid-market pricing convention for these inputs. We include, as a discount to the derivative asset, the effect of our counterparty credit risk based on current published credit default swap rates when the net fair value of our derivative instruments is in a net asset position. We consider our own nonperformance risk when the net fair value of our derivative instruments is in a net liability position by discounting our derivative liabilities to reflect the potential credit risk to our counterparty through applying a current market indicative credit spread to all cash flows.

The fair values of our derivative instruments were as follows:

Net unrealized loss on hedging instruments at June 30,	$	(14,678	)	$	(11,759	)

Reclassification of amounts related to hedging instruments are included in interest expense in the Consolidated Statements of Operations for the periods ended June 30, 2019 and 2018. Included in the net unrealized gain (loss) on hedging instruments at

June 30, 2019 and 2018 is a loss of $14.4 million, net of tax, related to our nonderivative net investment hedge, which terminated in 2011. This loss on our net investment hedge will remain in AOCI until earnings are impacted by a sale or liquidation of the associated foreign operation.

A summary of the effect of netting arrangements on our financial position related to the offsetting of our recognized derivative assets and liabilities under master netting arrangements or similar agreements is as follows:

Offsetting of Derivative Assets	Gross Amounts of Recognized Assets Presented in the Consolidated Balance Sheets		Gross Amounts Not Offset in the Consolidated Balance Sheets
In thousands			Derivative Financial Instruments			Cash Collateral Received		Net Amount
June 30, 2019	$	4,726	$	(69	)	$	—	$	4,657

December 31, 2018	$	337	$	(103	)	$	—	$	234

Our derivative assets and liabilities subject to netting arrangements consist of foreign exchange forwards and options and interest rate contracts with six counterparties at June 30, 2019 and five counterparties at December 31, 2018. No derivative asset or liability balance with any of our counterparties was individually significant at June 30, 2019 or December 31, 2018. Our derivative contracts with each of these counterparties exist under agreements that provide for the net settlement of all contracts through a single payment in a single currency in the event of default. We have no pledges of cash collateral against our obligations, and we have not received pledges of cash collateral from our counterparties under the associated derivative contracts.

Cash Flow Hedges

As a result of our floating rate debt, we are exposed to variability in our cash flows from changes in the applicable interest rate index. We enter into interest rate caps and swaps to reduce the variability of cash flows from increases in the LIBOR based borrowing rates on our floating rate credit facility. These instruments do not protect us from changes to the applicable margin under our credit facility. At June 30, 2019, our LIBOR-based debt balance was $615.6 million.

In October 2015, we entered into an interest rate swap, which is effective from August 31, 2016 to June 23, 2020, and converts $214 million of our LIBOR based debt from a floating LIBOR interest rate to a fixed interest rate of 1.42% (excluding the applicable margin on the debt). The notional balance will amortize to maturity at the same rate as required minimum payments on our term loan. Changes in the fair value of the interest rate swap are recognized as a component of other comprehensive income (OCI) and are recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedge are recognized as an adjustment to interest expense along with the earnings effect of the hedged item. The amount of net gains expected to be reclassified into earnings in the next 12 months is $0.7 million.

In November 2015, we entered into three interest rate cap contracts with a total notional amount of $100 million at a cost of $1.7 million. The interest rate cap contracts expire on June 23, 2020 and were entered into in order to limit our interest rate exposure on $100 million of our variable LIBOR based debt up to 2.00%. In the event LIBOR is higher than 2.00%, we will pay interest at the capped rate of 2.00% with respect to the $100 million notional amount of such agreements. As of December 31, 2016, due to the accelerated revolver payments from surplus cash, we elected to de-designate two of the interest rate cap contracts as cash flow hedges and discontinued the use of cash flow hedge accounting. The amounts recognized in AOCI from de-designated interest rate cap contracts were maintained in AOCI as the forecasted transactions were still probable to occur, and subsequent changes in fair value were recognized within interest expense. In April 2018, due to increases in our total LIBOR-based debt, we elected to re-designate the two interest rate cap contracts as cash flow hedges. Future changes in the fair value of these instruments will be recognized as a component of OCI, and these changes together with amounts previously maintained in AOCI will be recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedge are recognized as an adjustment to interest expense along with the earnings effect of the hedged item. The amount of net losses expected to be reclassified into earnings for all interest rate cap contracts in the next 12 months is $0.6 million.

In April 2018, we entered into a cross-currency swap, which converts $56.0 million of floating LIBOR-based U.S. Dollar denominated debt into 1.38% fixed rate euro denominated debt. This cross-currency swap matures on April 30, 2021 and mitigates the risk associated with fluctuations in currency rates impacting cash flows related to U.S. Dollar denominated debt in a euro functional currency entity. Changes in the fair value of the cross-currency swap are recognized as a component of OCI and will be recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedge are recognized as an adjustment to interest expense along with the earnings effect of the hedged item. The amount of net gains expected to be reclassified into earnings in the next 12 months is $1.3 million.

As a result of our forecasted purchases in non-functional currency, we are exposed to foreign exchange risk. We hedge portions of our forecasted foreign currency inventory purchases. During January 2019, we entered into foreign exchange option contracts for a total notional amount of $72 million at a cost of $1.3 million. The contracts will mature ratably through the year with final maturity in October 2019. Changes in the fair value of the option contracts are recognized as a component of OCI and will be recognized in product cost of revenues when the hedged item affects earnings.

These reclassification amounts presented above also represent the loss (gain) recognized in net income (loss) on hedging relationships under Subtopic 815-20 on the Consolidated Statements of Operations. For the three months and six months ended June 30, 2019 and 2018, there were no amounts reclassified from AOCI as a result that a forecasted transaction is no longer probable of occurring, and no amounts excluded from effectiveness testing recognized in earnings based on changes in fair value.

Derivatives Not Designated as Hedging Relationships

We are also exposed to foreign exchange risk when we enter into non-functional currency transactions, both intercompany and third party. At each period-end, non-functional currency monetary assets and liabilities are revalued with the change recognized to other income and expense. We enter into monthly foreign exchange forward contracts, which are not designated for hedge accounting, with the intent to reduce earnings volatility associated with currency exposures. As of June 30, 2019, a total of 48 contracts were offsetting our exposures from the Euro, Pound Sterling, Indonesian Rupiah, Chinese Yuan, Canadian Dollar, Indian Rupee and various other currencies, with notional amounts ranging from $131,000 to $9.4 million.

The effect of our derivative instruments not designated as hedges on the Consolidated Statements of Operations was as follows:

Note 8:    Defined Benefit Pension Plans

We sponsor both funded and unfunded defined benefit pension plans offering death and disability, retirement, and special termination benefits for our international employees, primarily in Germany, France, Italy, Indonesia, and India. The defined benefit obligation is calculated annually by using the projected unit credit method. The measurement date for the pension plans was December 31, 2018.

Amounts recognized on the Consolidated Balance Sheets consist of:

In thousands	June 30, 2019		December 31, 2018
Assets
Plan assets in other long-term assets	$	605	$	572

Long-term portion of pension benefit obligation	92,073		91,522
Pension benefit obligation, net	$	94,666	$	93,680

Our asset investment strategy focuses on maintaining a portfolio using primarily insurance funds, which are accounted for as investments and measured at fair value, in order to achieve our long-term investment objectives on a risk adjusted basis. Our general funding policy for these qualified pension plans is to contribute amounts sufficient to satisfy regulatory funding standards of the respective countries for each plan.

Net periodic pension benefit costs for our plans include the following components:

	Three Months Ended June 30,						Six Months Ended June 30,

The components of net periodic benefit cost, other than the service cost component, are included in total other income (expense) on the Consolidated Statements of Operations.

Note 9:    Stock-Based Compensation

We maintain the Second Amended and Restated 2010 Stock Incentive Plan (Stock Incentive Plan), which allows us to grant stock-based compensation awards, including stock options, restricted stock units, phantom stock, and unrestricted stock units. Under the Stock Incentive Plan, we have 12,623,538 shares of common stock reserved and authorized for issuance subject to stock splits, dividends, and other similar events. At June 30, 2019, 6,340,860 shares were available for grant under the Stock Incentive Plan. We issue new shares of common stock upon the exercise of stock options or when vesting conditions on restricted stock units are fully satisfied. These shares are subject to a fungible share provision such that the authorized share reserve is reduced by (i) one share for every one share subject to a stock option or share appreciation right granted under the Plan and (ii) 1.7 shares for every one share of common stock that was subject to an award other than an option or share appreciation right.

As part of the acquisition of SSNI, we reserved and authorized 2,880,039 shares, collectively, of Itron common stock to be issued under the Stock Incentive Plan for certain SSNI common stock awards that were converted to Itron common stock awards on January 5, 2018 (Acquisition Date) pursuant to the Agreement and Plan of Merger or were available for issuance pursuant to future awards under the Silver Spring Networks, Inc. 2012 Equity Incentive Plan (SSNI Plan). New stock-based compensation awards originally from the SSNI Plan may only be made to individuals who were not employees of Itron as of the Acquisition Date. Notwithstanding the foregoing, there is no fungible share provision for shares originally from the SSNI Plan. 

17

We also periodically award phantom stock units, which are settled in cash upon vesting and accounted for as liability-based awards with no impact to the shares available for grant.

In addition, we maintain the Employee Stock Purchase Plan (ESPP), for which 255,845 shares of common stock were available for future issuance at June 30, 2019.

Unrestricted stock and ESPP activity for the three and six months ended June 30, 2019 and 2018 was not significant.

At June 30, 2019, total unrecognized compensation expense on phantom stock units was $2.8 million, which is expected to be recognized over a weighted average period of approximately 1.9 years. As of both June 30, 2019 and December 31, 2018, we have recognized a phantom stock liability of $0.7 million and $1.5 million, respectively, within wages and benefits payable in the Consolidated Balance Sheets.

Note 10: Income Taxes

We determine the interim tax benefit (provision) by applying an estimate of the annual effective tax rate to the year-to-date pretax book income (loss) and adjusting for discrete items during the reporting period, if any. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded.

Our tax rate for the three and six months ended June 30, 2019 of 30% and 42%, respectively, differed from the federal statutory rate of 21% primarily due to losses in jurisdictions for which no benefit is recognized because of valuation allowances on deferred tax assets as well as the forecasted mix of earnings in domestic and international jurisdictions.

Our tax rate for the three and six months ended June 30, 2018 of 50% and 5%, respectively, differed from the federal statutory rate of 21% primarily due to losses in jurisdictions for which no benefit is recognized because of valuation allowances on deferred tax assets as well as the forecasted mix of earnings in domestic and international jurisdictions, a benefit related to excess stock-based compensation, and uncertain tax positions.

We classify interest expense and penalties related to unrecognized tax liabilities and interest income on tax overpayments as components of income tax expense. The net interest and penalties expense recognized were as follows:

	Three Months Ended June 30,					Six Months Ended June 30,
In thousands	2019			2018		2019		2018
Net interest and penalties expense	$	(42	)	$	315	$	259	$	739

Accrued interest and penalties recognized were as follows:

In thousands	June 30, 2019		December 31, 2018
Accrued interest	$	2,383	$	2,127
Accrued penalties	1,774		1,758

20

Unrecognized tax benefits related to uncertain tax positions and the amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate were as follows:

In thousands	June 30, 2019		December 31, 2018
Unrecognized tax benefits related to uncertain tax positions	$	115,282	$	112,558
The amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate	113,952		111,224

At June 30, 2019, we are under examination by certain tax authorities for the 2010 to 2017 tax years. The material jurisdictions where we are subject to examination for the 2010 to 2017 tax years include, among others, the United States, France, Germany, Italy, Brazil and the United Kingdom. No material changes have occurred to previously disclosed assessments. We believe we have appropriately accrued for the expected outcome of all tax matters and do not currently anticipate that the ultimate resolution of these examinations will have a material adverse effect on our financial condition, future results of operations, or liquidity.

Based upon the timing and outcome of examinations, litigation, the impact of legislative, regulatory, and judicial developments, and the impact of these items on the statute of limitations, it is reasonably possible that the related unrecognized tax benefits could change from those recognized within the next twelve months. However, at this time, an estimate of the range of reasonably possible adjustments to the balance of unrecognized tax benefits cannot be made.

Note 11:    Commitments and Contingencies

Guarantees and Indemnifications

We are often required to obtain standby letters of credit (LOCs) or bonds in support of our obligations for customer contracts. These standby LOCs or bonds typically provide a guarantee to the customer for future performance, which usually covers the installation phase of a contract and may, on occasion, cover the operations and maintenance phase of outsourcing contracts.

Our available lines of credit, outstanding standby LOCs, and performance bonds were as follows:

In thousands	June 30, 2019			December 31, 2018

Net available for additional borrowings and LOCs	$	85,010		$	86,421
Unsecured surety bonds in force	$	102,146		$	94,365

In the event any such standby LOC or bond is called, we would be obligated to reimburse the issuer of the standby LOC or bond; however, we do not believe that any outstanding LOC or bond will be called.

We generally provide an indemnification related to the infringement of any patent, copyright, trademark, or other intellectual property right on software or equipment within our sales contracts, which indemnifies the customer from and pays the resulting costs, damages, and attorney's fees awarded against a customer with respect to such a claim provided that (a) the customer promptly notifies us in writing of the claim and (b) we have the sole control of the defense and all related settlement negotiations. We may also provide an indemnification to our customers for third-party claims resulting from damages caused by the negligence or willful misconduct of our employees/agents in connection with the performance of certain contracts. The terms of our indemnifications

21

generally do not limit the maximum potential payments. It is not possible to predict the maximum potential amount of future payments under these or similar agreements.

Legal Matters

We are subject to various legal proceedings and claims of which the outcomes are subject to significant uncertainty. Our policy is to assess the likelihood of any adverse judgments or outcomes related to legal matters, as well as ranges of probable losses. A determination of the amount of the liability required, if any, for these contingencies is made after an analysis of each known issue. A liability is recognized and charged to operating expense when we determine that a loss is probable and the amount can be reasonably estimated. Additionally, we would disclose contingencies for which a material loss is reasonably possible, but not probable.

Warranty

A summary of the warranty accrual account activity is as follows:

Total warranty expense	$	6,187	$	5,901	$	7,966	$	10,763

Health Benefits

We are self-insured for a substantial portion of the cost of our U.S. employee group health insurance. We purchase insurance from a third party, which provides individual and aggregate stop loss protection for these costs. Each reporting period, we expense the costs of our health insurance plan including paid claims, the change in the estimate of incurred but not reported (IBNR) claims, taxes, and administrative fees (collectively, the plan costs).

Plan costs were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
In thousands	2019		2018		2019		2018
Plan costs	$	7,923	$	7,673	$	14,801	$	16,354

In thousands	June 30, 2019		December 31, 2018
IBNR accrual	$	3,213	$	3,643

Our IBNR accrual and expenses may fluctuate due to the number of plan participants, claims activity, and deductible limits. For our employees located outside of the United States, health benefits are provided primarily through governmental social plans, which are funded through employee and employer tax withholdings.

Note 12:    Restructuring

2018 Projects

On February 22, 2018, our Board of Directors approved a restructuring plan (the 2018 Projects) to continue our efforts to optimize our global supply chain and manufacturing operations, research and development, and sales and marketing organizations. We expect to substantially complete the plan by the end of 2020. Many of the affected employees are represented by unions or works councils, which require consultation, and potential restructuring projects may be subject to regulatory approval, both of which could impact the timing of charges, total expected charges, cost recognized, and planned savings in certain jurisdictions.

The total expected restructuring costs, the restructuring costs recognized, and the remaining expected restructuring costs related to the 2018 Projects are as follows:

In thousands	Total Expected Costs at June 30, 2019		Costs Recognized in Prior Periods		Costs Recognized During the Six Months Ended June 30, 2019			Expected Remaining Costs to be Recognized at June 30, 2019

Total	$	97,870	$	78,123	$	4,457		$	15,290

2016 Projects

On September 1, 2016, we announced projects (2016 Projects) to restructure various company activities in order to improve operational efficiencies, reduce expenses and improve competitiveness. We closed or consolidated several facilities and reduced our global workforce as a result of the restructuring. The 2016 Projects were initiated during the third quarter of 2016 and were substantially completed at December 31, 2018.

During the three months ended June 30, 2019, we completed the sale of our property in Stretford, United Kingdom. A gain on sale of $5.4 million was included in restructuring expense in the Consolidated Statement of Operations.

The total expected restructuring costs, the restructuring costs recognized, and the remaining expected restructuring costs related to the 2016 Projects are as follows:

In thousands	Total Expected Costs at June 30, 2019		Costs Recognized in Prior Periods		Costs Recognized During the Six Months Ended June 30, 2019			Expected Remaining Costs to be Recognized at June 30, 2019
Employee severance costs	$	36,283	$	35,845	$	438		$	—
Asset impairments & net loss (gain) on sale or disposal	255		5,664		(5,409		)	—
Other restructuring costs	14,070		11,763		1,607			700
Total	$	50,608	$	53,272	$	(3,364	)	$	700

The following table summarizes the activity within the restructuring related balance sheet accounts for the 2018 and 2016 Projects during the six months ended June 30, 2019:

In thousands	Accrued Employee Severance			Asset Impairments & Net Loss on Sale or Disposal			Other Accrued Costs			Total

Ending balance, June 30, 2019	$	63,250		$	(5,307	)	$	7,770		$	65,713

Asset impairments are determined at the asset group level. Revenues and net operating income from the activities we have exited or will exit under the restructuring projects are not material to our operating segments or consolidated results.

23

Other restructuring costs include expenses for employee relocation, professional fees associated with employee severance, and costs to exit the facilities once the operations in those facilities have ceased. Costs associated with restructuring activities are generally presented in the Consolidated Statements of Operations as restructuring, except for certain costs associated with inventory write-downs, which are classified within cost of revenues, and accelerated depreciation expense, which is recognized according to the use of the asset.

The current portion of restructuring liabilities was $24.4 million and $36.0 million as of June 30, 2019 and December 31, 2018. The current portion of restructuring liabilities is classified within other current liabilities on the Consolidated Balance Sheets. The long-term portion of restructuring liabilities balances was $41.3 million and $39.6 million as of June 30, 2019 and December 31, 2018. The long-term portion of restructuring liabilities is classified within other long-term obligations on the Consolidated Balance Sheets and include severance accruals and facility exit costs.

Note 13:    Shareholders' Equity

Preferred Stock

We have authorized the issuance of 10 million shares of preferred stock with no par value. In the event of a liquidation, dissolution, or winding up of the affairs of the corporation, whether voluntary or involuntary, the holders of any outstanding preferred stock will be entitled to be paid a preferential amount per share to be determined by the Board of Directors prior to any payment to holders of common stock. There was no preferred stock issued or outstanding at June 30, 2019 and December 31, 2018.

Stock Repurchase Authorization

On March 14, 2019, Itron's Board of Directors authorized the Company to repurchase up to $50 million of our common stock over a 12-month period (the 2019 Stock Repurchase Program). Following the announcement of the program and through June 30, 2019, we repurchased 529,396 shares at an average share price of $47.22 (including commissions) for a total of $25 million. The remaining amount authorized for repurchase under the 2019 Stock Repurchase Program is $25 million. In accordance with the terms of our 5% senior notes indenture maturing January 15, 2026, we are limited to a total of $25 million in stock repurchases in 2019. As we have already met that threshold, we will not repurchase any more shares for the remainder of 2019.

The following methods and assumptions were used in estimating fair values:

Cash, cash equivalents, and restricted cash: Due to the liquid nature of these instruments, the carrying amount approximates fair value (Level 1).

Credit Facility - term loan and multicurrency revolving line of credit: The term loan and revolver are not traded publicly. The fair values, which are determined based upon a hypothetical market participant, are calculated using a discounted cash flow model with Level 2 inputs, including estimates of incremental borrowing rates for debt with similar terms, maturities, and credit profiles. Refer to "Note 6: Debt" for a further discussion of our debt.

Derivatives: See "Note 7: Derivative Financial Instruments" for a description of our methods and assumptions in determining the fair value of our derivatives, which were determined using Level 2 inputs.

Senior Notes: The Notes are not registered securities nor listed on any securities exchange but may be actively traded by qualified institutional buyers. The fair value is estimated using Level 1 inputs, as it is based on quoted prices for these instruments in active markets.

The fair values at June 30, 2019 and December 31, 2018 do not reflect subsequent changes in the economy, interest rates, tax rates, and other variables that may affect the determination of fair value.

Note 15:    Segment Information

Effective October 1, 2018, we reorganized our operational reporting segmentation from Electricity, Gas, Water, and Networks to Device Solutions, Networked Solutions, and Outcomes. Prior period segment results have been recast to conform to the new segment structure. As part of our reorganization, we actively integrated our recent acquisitions and are making investment decisions and implementing an organizational structure that aligns with these new segments. In conjunction with the rollout of our new operating segments, we unified our go-to-market strategy with a single, global, sales force that sells the full portfolio of Itron solutions, products and services. We continue to manage our research and development, service delivery, supply chain, and manufacturing operations on a worldwide basis to promote global, integrated oversight of our operations and to ensure consistency and interoperability between our operating segments.

With this reorganization, we continue to operate under the Itron brand worldwide and will manage and report under the three operating segments: Device Solutions, Networked Solutions, and Outcomes.

26

We have three GAAP measures of segment performance: revenues, gross profit (gross margin), and operating income (operating margin). Intersegment revenues are minimal. Certain operating expenses are allocated to the operating segments based upon internally established allocation methodologies. Corporate operating expenses, interest income, interest expense, other income (expense), and income tax provision are neither allocated to the segments, nor are they included in the measure of segment profit or loss. In addition, we allocate only certain production assets and intangible assets to our operating segments. We do not manage the performance of the segments on a balance sheet basis.

Segment Products

Device Solutions	Device Solutions - includes hardware products used for measurement, control, or sensing that do not have communications capability embedded for use with our broader Itron systems, i.e., products where Itron is not offering the complete "end-to-end" solution, but only the hardware elements. Examples of the Device Solutions portfolio include standard endpoints that are shipped without Itron communications, such as our standard gas meters, electricity IEC meters, and water meters, in addition to our heat and allocation products; communicating meters that are not a part of an Itron solution such as the Linky meter; and the implementation and installation of non-communicating devices, such as gas regulators.
Networked Solutions	Networked Solutions - includes a combination of communicating devices (smart meters, modules, endpoints, and sensors), network infrastructure, and associated application software designed and sold as a complete solution for acquiring and transporting robust application-specific data. Networked Solutions combines, into one operating segment, the majority of the assets from the recently acquired SSNI organization with our legacy Itron networking products and software and the implementation and installation of communicating devices into one segment. This includes: communicating measurement, control, or sensing endpoints such as our Itron® and OpenWay® Riva meters, Itron traditional ERT® technology, Intelis smart gas or water meters, 500G gas communication modules, 500W water communication modules; GenX networking products, network modules and interface cards; and specific network control and management software applications. Solutions supported by this segment include automated meter reading (AMR), advanced metering infrastructure (AMI), smart grid and distribution automation (DA), and smart street lighting and smart city solutions.
Outcomes	Outcomes - includes our value-added, enhanced software and services operating segment in which we manage, organize, analyze, and interpret data to improve decision making, maximize operational profitability, drive resource efficiency, and deliver results for consumers, utilities, and smart cities. Outcomes places an emphasis on delivering to Itron customers high-value, turn-key, digital experiences by leveraging the footprint of our Device Solutions and Networked Solutions segments. The revenues from these offerings are primarily recurring in nature and would include any direct management of Device Solutions, Networked Solutions, and other products on behalf of our end customers. Examples of these offerings include our meter data management and analytics offerings; our managed service solutions including network-as-a-service and platform-as-a-service, forecasting software and services; and any consulting-based engagement. Within the Outcomes segment, we also identify new business models, including performance-based contracting, to drive broader portfolio offerings across utilities and cities.

For the three and six months ended June 30, 2019, one customer represented 11% of total company revenues. For the three months ended June 30, 2018, one customer represented 10% of total company revenues, and no single customer represented more than 10% of total company revenues for the six months ended June 30, 2018.

We currently buy a majority of our integrated circuit board assemblies from three suppliers. Management believes that other suppliers could provide similar products, but a change in suppliers, disputes with our suppliers, or unexpected constraints on the suppliers' production capacity could adversely affect operating results.

Note 16: Revenues

A summary of significant net changes in the contract assets and the contract liabilities balances during the period is as follows:

	2019
In thousands	Contract liabilities, less contract assets
Beginning balance, January 1	$	102,130
Revenues recognized from beginning contract liability	(41,873		)
Increases due to amounts collected or due	184,808
Revenues recognized from current period increases	(129,074		)
Other	(9,053		)
Ending balance, June 30	$	106,938

On January 1, 2019, total contract assets were $34.3 million and total contract liabilities were $136.5 million. On June 30, 2019, total contract assets were $37.4 million and total contract liabilities were $144.4 million. The contract assets primarily relate to contracts that include a retention clause and allocations related to contracts with multiple performance obligations. The contract liabilities primarily relate to deferred revenue, such as extended warranty and maintenance cost.

Transaction price allocated to the remaining performance obligations

Total transaction price allocated to remaining performance obligations represents committed but undelivered products and services for contracts and purchase orders at period end. Twelve-month remaining performance obligations represent the portion of total transaction price allocated to remaining performance obligations that we estimate will be recognized as revenue over the next 12 months. Total transaction price allocated to remaining performance obligations is not a complete measure of our future revenues as we also receive orders where the customer may have legal termination rights but are not likely to terminate.

Total transaction price allocated to remaining performance obligations related to contracts is approximately $1.3 billion for the next twelve months and approximately $929 million for periods longer than 12 months. The total remaining performance obligations is comprised of product and service components. The service component relates primarily to maintenance agreements for which customers pay a full year's maintenance in advance, and service revenues are generally recognized over the service period. Total transaction price allocated to remaining performance obligations also includes our extended warranty contracts, for which revenue is recognized over the warranty period, and hardware, which is recognized as units are delivered. The estimate of when remaining performance obligations will be recognized requires significant judgment.

Cost to obtain a contract and cost to fulfill a contract with a customer

Cost to obtain a contract and costs to fulfill a contract are capitalized and amortized using a systematic rational approach to align with the transfer of control of underlying contracts with customers. While amounts were capitalized, they are not material.

Disaggregation of revenue

Refer to "Note 15: Segment Information" and the Consolidated Statement of Operations for disclosure regarding the disaggregation of revenue into categories, which depict how revenue and cash flows are affected by economic factors. Specifically, our operating segments, geographical regions, and categories for products, which include hardware and software and services, are presented.

Note 17: Leases

We lease certain factories, service and distribution locations, offices, and equipment under operating leases. Our operating leases have initial lease terms ranging from 1 to 9 years, some of which include options to extend or renew the leases for up to 10 years. Certain lease agreements contain provisions for future rent increases. Our leases do not contain material residual value guarantees and finance leases are not material.

Overview

We are a technology company, offering end-to-end solutions to enhance productivity and efficiency, primarily focused on utilities and municipalities around the globe. Our solutions generally include robust industrial grade networks, smart meters, meter data management software, and knowledge application solutions, which bring additional value to the customer. Our professional services help our customers project-manage, install, implement, operate, and maintain their systems.

We operate under the Itron brand worldwide and manage and report under three operating segments: Device Solutions, Networked Solutions, and Outcomes. The product and operating definitions of the three segments are as follows:

Device Solutions: primarily includes hardware products used for measurement, control, or sensing that do not have communications capability embedded for use with our broader Itron systems, i.e., products where Itron is not offering the complete “end-to-end” solution, but only the hardware elements. Examples of the Device Solutions portfolio include standard endpoints that are shipped without Itron communications, such as our standard gas meters, electricity IEC meters, and water meters, in addition to our heat and allocation products; communicating meters that are not a part of an Itron solution such as the Linky meter; and the implementation and installation of non-communicating devices, such as gas regulators.

Networked Solutions: primarily includes a combination of communicating devices (smart meters, modules, endpoints and sensors), network infrastructure, and associated application software designed and sold as a complete solution for acquiring and transporting robust application-specific data. Networked Solutions combines, into one operating segment, the majority of the assets from the recently acquired Silver Spring Networks organization with our legacy Itron networking products and software, and the implementation and installation of communicating devices into one segment. This includes: communicating measurement, control, or sensing endpoints such as our Itron® and OpenWay® Riva meters, Itron traditional ERT® technology, Intelis Smart gas or

31

water meters, 500G gas communication modules, 500W water communication modules; GenX networking products, network modules and interface cards, and specific network control and management software applications. The industrial Internet of Things (IIoT) solutions supported by this segment include automated meter reading (AMR), advanced metering infrastructure (AMI), smart grid and distribution automation (DA), and smart street lighting and smart city solutions.

Outcomes: represents our value-added, enhanced software and services operating segment in which we manage, organize, analyze, and interpret data to improve decision making, maximize operational profitability, drive resource efficiency, and deliver results for consumers, utilities and smart cities. Outcomes places an emphasis on delivering Itron customers high-value, turn-key, digital experiences by leveraging the footprint of our Device Solutions and Networked Solutions segments. The revenues from these offerings are primarily recurring in nature and would include any direct management of Device Solutions, Networked Solutions, and other products on behalf of our end customers. Examples of these offerings include our meter data management and analytics offerings, our managed service solutions including network-as-a-service and platform-as-a-service, forecasting software and services, and any consulting-based engagement. Within the Outcomes segment we also identify new business models, including performance-based contracting, to drive broader portfolio offerings across utilities and cities.

We have three measures of segment performance: revenues, gross profit (margin), and operating income (margin). Intersegment revenues are minimal. Certain operating expenses are allocated to the operating segments based upon internally established allocation methodologies. Interest income, interest expense, other income (expense), income tax provision, and certain corporate operating expenses are neither allocated to the segments nor included in the measures of segment performance.

Non-GAAP Measures

The following discussion includes financial information prepared in accordance with accounting principles generally accepted in the United States (GAAP), as well as certain adjusted or non-GAAP financial measures such as constant currency, free cash flow, non-GAAP operating expenses, non-GAAP operating income, non-GAAP net income, adjusted EBITDA, and non-GAAP diluted earnings per share (EPS). We believe that non-GAAP financial measures, when reviewed in conjunction with GAAP financial measures, can provide more information to assist investors in evaluating current period performance and in assessing future performance. For these reasons, our internal management reporting also includes non-GAAP measures. We strongly encourage investors and shareholders to review our financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure. Non-GAAP measures as presented herein may not be comparable to similarly titled measures used by other companies.

In our discussions of the operating results below, we sometimes refer to the impact of foreign currency exchange rate fluctuations, which are references to the differences between the foreign currency exchange rates we use to convert operating results from local currencies into U.S. dollars for reporting purposes. We also use the term "constant currency," which represents results adjusted to exclude foreign currency exchange rate impacts. We calculate the constant currency change as the difference between the current period results translated using the current period currency exchange rates and the comparable prior period's results restated using current period currency exchange rates. We believe the reconciliations of changes in constant currency provide useful supplementary information to investors in light of fluctuations in foreign currency exchange rates.

Refer to the Non-GAAP Measures section below on pages 46-48 for information about these non-GAAP measures and the detailed reconciliation of items that impacted free cash flow, non-GAAP operating expense, non-GAAP operating income, non-GAAP net income, adjusted EBITDA, and non-GAAP diluted EPS in the presented periods.

Stock Repurchase Authorization

On March 14, 2019, Itron's Board of Directors authorized the Company to repurchase up to $50 million of our common stock over a 12-month period (the 2019 Stock Repurchase Program). Following the announcement of the program and through June 30, 2019, we repurchased 529,396 shares at an average share price of $47.22 (including commissions) for a total of $25 million. The remaining amount authorized for repurchase under the 2019 Stock Repurchase Program is $25 million. In accordance with the terms of our 5% senior notes indenture maturing January 15, 2026, we are limited to a total of $25 million in stock repurchases in 2019. As we have already met that threshold, we will not repurchase any more shares for the remainder of 2019.

2018 Restructuring Projects

On February 22, 2018, our Board of Directors approved a restructuring plan (2018 Projects) to continue our efforts to optimize our global supply chain and manufacturing operations, research and development, and sales and marketing organizations. We expect to substantially complete expense recognition on the plan by the end of 2020. We recognized a reversal of restructuring expense of $1.2 million compared with restructuring expense of $4.5 million related to the 2018 Projects during the three and six months ended June 30, 2019, respectively, and we anticipate an additional $15.3 million to be recognized in future periods. At the conclusion of the 2018 Projects, we anticipate annualized savings of $45 million to $50 million. For further discussion of restructuring activities, refer to Item 1: "Financial Statements (Unaudited), Note 12: Restructuring."

Endpoints Summary

Our revenue is driven significantly by sales of endpoints. We classify our endpoints into two categories:

• Standard Endpoints – an Itron product delivered primarily via our Device Solutions segment. The majority of our standard endpoint devices are used for delivery and metrology in the electricity, water, and gas distribution industries, and have no built-in remote reading communication technology. However, some standard endpoint devices are shipped with non-Itron communications capabilities and are not a part of an Itron solution, such as the Smart Spec or Linky meter, and are classified as a standard endpoint.

• Networked Endpoints – an Itron product with one-way communication or two-way communication of data including remote device configuration and upgrade (consisting primarily of our OpenWay® or Gen X technology). This primarily includes Itron devices used in electricity, water, and gas distribution industries delivered via our Networked Solutions segment. Networked endpoints also include smart communication modules and network interface cards (NICs). NICs are communicating modules that can be sold separately from the device directly to our customers or to third party manufacturers for use in endpoints such as electric, water, and gas meters; streetlights and smart city devices; sensors or another standard device that the end customer would like to connect to our OpenWay or Gen X Networked Solutions. These endpoints are primarily delivered via our Networked Solutions segment.

A summary of our endpoints shipped is as follows:

	Three Months Ended June 30,		Six Months Ended June 30,
Units in thousands	2019	2018	2019	2018
Itron Endpoints
Standard endpoints (1)	5,570	5,860	11,040	11,640
Networked endpoints (1)	4,260	3,570	8,240	7,470
Total endpoints	9,830	9,430	19,280	19,110

⁽¹⁾ As of the second quarter of 2019, we have refined the definition of a standard endpoint to more closely align to the segment performance of Device Solutions and Networked Solutions as reported in the Operating Segment Results section below. The quantities presented for the three and six months ended June 30, 2018 and for the three months ended March 31, 2019, as included in the six-month period for 2019, have been recast to align with the refined definitions of standard and networked endpoints. The total endpoints shipped for each period is unchanged.

⁽¹⁾  Constant currency change is a non-GAAP financial measure and represents the total change between periods excluding the effect of changes in foreign currency exchange rates.

Operating expenses decreased $8.4 million for the three months ended June 30, 2019 as compared with the same period in 2018. This was primarily due to the decrease of $5.3 million in research and development, and the decrease of $1.9 million in amortization of intangible assets. These amounts are net of increases in variable compensation.

36

Operating expenses decreased $162.2 million for the six months ended June 30, 2019 as compared with the same period in 2018. This was primarily due to the $81.1 million decrease in restructuring expense, which was elevated during the six months ended June 30, 2018 following the announcement of the 2018 Project, and $62.3 million decreased in sales, general and administrative expenses. Acquisition and integration costs, which are classified within sales, general and administrative expenses, decreased by $53.0 million compared with the same period in 2018.

The change in other income (expense), net, for the three and six months ended June 30, 2019 as compared with the same periods in 2018 was the result of a legal settlement gain of $2.5 million recognized in the second quarter of 2018 and the effect of recognized foreign currency exchange gains and losses due to transactions denominated in a currency other than the reporting entity's functional currency.

Income Tax Provision

For the three and six months ended June 30, 2019, our income tax expense was $8.4 million and $14.5 million compared with income tax expense and benefit of $3.8 million and $(7.4) million for the same periods in 2018. Our tax rate for the three and six months ended June 30, 2019 of 30% and 42% differed from the federal statutory rate of 21% due to the forecasted mix of earnings in domestic and international jurisdictions and losses experienced in jurisdictions with valuation allowances on deferred tax assets. Our tax rate for the three and six months ended June 30, 2018 of 50% and 5% differed from the federal statutory rate of 21% due to the forecasted mix of earnings in domestic and international jurisdictions, a benefit related to excess stock based compensation, and losses experienced in jurisdictions with valuation allowances on deferred tax assets.

⁽¹⁾  Constant currency change is a non-GAAP financial measure and represents the total change between periods excluding the effect of changes in foreign currency exchange rates.

Revenues - Three months ended June 30, 2019 vs. Three months ended June 30, 2018

Revenues decreased $18.4 million, or 8% for the three months ended June 30, 2019 compared with the same period in 2018. During the three months ended June 30, 2019, product revenue decreased due to lower shipments for certain customer projects in Europe, Middle East, and Africa (EMEA) offset by higher product sales in North America. Changes in foreign currency exchange rates unfavorably impacted revenues by $12.1 million.

Revenues - Six months ended June 30, 2019 vs. Six months ended June 30, 2018

Revenues decreased $46.0 million, or 9%. Changes in foreign currency exchange rates unfavorably impacted revenues by $29.1 million. The decrease in revenue was also due to reduced shipments for certain customer projects in EMEA offset by higher product sales in North America.

Gross Margin - Three months ended June 30, 2019 vs. Three months ended June 30, 2018

Gross margin was 19.1% for the three months ended June 30, 2019, compared with 20.6% for the same period in 2018. The 150 basis point decrease over the prior year was primarily the result of increased component costs, partially offset by reduced warranty expense.

Gross Margin - Six months ended June 30, 2019 vs. Six months ended June 30, 2018

For the six months ended June 30, 2019, gross margin was 18.5%, compared with 21.1% for the first six months in 2018. During 2019, the 260 basis point reduction over the prior year was primarily the result of increased component costs and partially offset by reduced variable warranty expense.

Operating Expenses - Three months ended June 30, 2019 vs. Three months ended June 30, 2018

Operating expenses decreased $1.0 million, or 7%, for the three months ended June 30, 2019, compared with the same period in 2018. The decrease was primarily a result of lower research and development expense, offset by higher product marketing expense.

Operating Expenses - Six months ended June 30, 2019 vs. Six months ended June 30, 2018

Operating expenses decreased $2.0 million, or 7%, for the six months ended June 30, 2019, compared with the same period in 2018. The decrease was primarily a result of lower research and development expense, offset by higher product marketing expense.

⁽¹⁾  Constant currency change is a non-GAAP financial measure and represents the total change between periods excluding the effect of changes in foreign currency exchange rates.

Revenues - Three months ended June 30, 2019 vs. Three months ended June 30, 2018

Revenues increased $7.8 million, or 15%, for the three months ended June 30, 2019, compared with the same period in 2018. The increase was driven by growth in software licenses and customer projects. Revenues were unfavorably impacted by $0.9 million due to changes in foreign currency exchange rates.

Revenues - Six months ended June 30, 2019 vs. Six months ended June 30, 2018

Revenues increased $8.7 million, or 8%, for the six months ended June 30, 2019, compared with the same period in 2018. This growth was driven by software licenses and customer projects. Revenues were unfavorably impacted by $2.2 million due to changes in foreign currency exchange rates.

Gross Margin - Three months ended June 30, 2019 vs. Three months ended June 30, 2018

Gross margin increased to 38.1%, compared with 29.0% in 2018. The 910 basis point increase in gross margin was driven primarily by the growth in higher margin software licenses and professional services.

Gross Margin - Six months ended June 30, 2019 vs. Six months ended June 30, 2018

Gross margin increased to 37.1% for the six months ended June 30, 2019, compared with 25.3% for the same period last year. The 1180 basis point increase was driven by growth in higher margin software licenses and professional services.

Operating Expenses - Three months ended June 30, 2019 vs. Three months ended June 30, 2018

Operating expenses for the three months ended June 30, 2019 decreased $2.3 million, or 20%, compared with 2018. This was primarily related to lower research and development expenses.

Operating Expenses - Six months ended June 30, 2019 vs. Six months ended June 30, 2018

Operating expenses for the six months ended June 30, 2019 decreased $5.1 million, or 21%, compared with the same period last year. This was primarily related to lower research and development and product marketing expenses.

Corporate unallocated:

Corporate Unallocated Expenses - Three months ended June 30, 2019 vs. Three months ended June 30, 2018

Operating expenses not directly associated with an operating segment are classified as "Corporate unallocated." These expenses decreased by $2.9 million, or 3%, for the three months ended June 30, 2019 compared with the same period in 2018. This was

41

primarily due to decreases in sales, general and administrative expenses and research and development spending, net of an increase in variable compensation.

Corporate Unallocated Expenses - Six months ended June 30, 2019 vs. Six months ended June 30, 2018

Corporate unallocated expenses decreased by $150.5 million, or 42%, for the six months ended June 30, 2019 compared with the same period in 2018. The decrease was primarily due to lower restructuring expense and lower SSNI acquisition and integration expense in 2019.

Bookings and Backlog of Orders

Bookings for a reported period represent customer contracts and purchase orders received during the period for hardware, software, and services that have met certain conditions, such as regulatory and/or contractual approval. Total backlog represents committed but undelivered products and services for contracts and purchase orders at period-end. Twelve-month backlog represents the portion of total backlog that we estimate will be recognized as revenue over the next 12 months. Backlog is not a complete measure of our future revenues as we also receive significant book-and-ship orders, as well as frame contracts. Bookings and backlog may fluctuate significantly due to the timing of large project awards. In addition, annual or multi-year contracts are subject to rescheduling and cancellation by customers due to the long-term nature of the contracts. Beginning total backlog, plus bookings, minus revenues, will not equal ending total backlog due to miscellaneous contract adjustments, foreign currency fluctuations, and other factors. Total bookings and backlog include certain contracts with termination for convenience clause, which will not agree to the total transaction price allocated to remaining performance obligations disclosed in Item 8: "Financial Statements and Supplementary Data, Note 16: Revenues".

Financial Condition

Cash Flow Information:

	Six Months Ended June 30,
In thousands	2019			2018
Cash provided by operating activities	$	78,063		$	16,879
Cash used in investing activities	(16,738		)	(832,340		)
Cash provided by (used in) financing activities	(46,527		)	498,009
Effect of exchange rates on cash, cash equivalents, and restricted cash	727			(4,841		)
Increase (decrease) in cash, cash equivalents, and restricted cash	$	15,525		$	(322,293	)

Cash, cash equivalents, and restricted cash was $137.9 million at June 30, 2019, compared with $122.3 million at December 31, 2018. The $15.5 million increase in cash, cash equivalents, and restricted cash for the six months ended June 30, 2019 was primarily the result of cash flows from operations, partially offset by acquisitions of property, plant, and equipment; repurchases of shares; and net payments on debt.

Operating activities

Cash provided by operating activities during the six months ended June 30, 2019 was $78.1 million compared with cash provided by operating activities of $16.9 million during the same period in 2018. The increase was primarily due to increased gross profit and lower cash outflows for acquisition and integration costs and restructuring costs.

Investing activities

Cash used by investing activities during the six months ended June 30, 2019 was $815.6 million higher compared with the same period in 2018. This decrease in use of cash was primarily related to the acquisition of SSNI in 2018.

42

Financing activities

Net cash used in financing activities during the six months ended June 30, 2019 was $46.5 million, compared with net cash provided of $498.0 million for the same period in 2018. In 2018, we had net draws on our debt of $519.7 million to fund the acquisition of SSNI, as well as cash payments of $24.0 million for debt origination fees. In 2019, we had stock repurchases of $25.0 million and net repayments of debt of $22.2 million.

Effect of exchange rates on cash and cash equivalents

The effect of exchange rates on the cash balances of currencies held in foreign denominations for the six months ended June 30, 2019 was an increase of $0.7 million, compared with a decrease of $4.8 million for the same period in 2018. The impact of exchange rates is the result of an increase in the U.S. dollar value compared with most foreign currencies during the six months ended June 30, 2019, compared with a decrease in value compared with most foreign currencies during the same period in 2018.

Free cash flow (Non-GAAP)

To supplement our Consolidated Statements of Cash Flows presented on a GAAP basis, we use the non-GAAP measure of free cash flow to analyze cash flows generated from our operations. The presentation of non-GAAP free cash flow is not meant to be considered in isolation or as an alternative to net income as an indicator of our performance, or as an alternative to cash flows from operating activities as a measure of liquidity. We calculate free cash flows, using amounts from our Consolidated Statements of Cash Flows, as follows:

	Six Months Ended June 30,
In thousands	2019			2018
Cash provided by operating activities	$	78,063		$	16,879
Acquisitions of property, plant, and equipment	(26,511		)	(29,309		)
Free cash flow	$	51,552		$	(12,430	)

Free cash flow increased primarily as a result of higher cash provided by operating activities due to a significant decrease in acquisition and integration costs related to our acquisition of SSNI in the 2018 period. See the cash flow discussion of operating activities above. In addition, acquisition of property, plant, and equipment decreased $2.8 million during the six months ended June 30, 2019 primarily due to investments related to our strategic sourcing projects and related manufacturing and supplier transitions in 2018.

Off-balance sheet arrangements:

We have no off-balance sheet financing agreements or guarantees as defined by Item 303 of Regulation S-K at June 30, 2019 and December 31, 2018 that we believe are reasonably likely to have a current or future effect on our financial condition, results of operations, or cash flows.

Liquidity and Capital Resources:

Our principal sources of liquidity are cash flows from operations, borrowings, and sales of common stock. Cash flows may fluctuate and are sensitive to many factors including changes in working capital and the timing and magnitude of capital expenditures and payments of debt. Working capital, which represents current assets less current liabilities, continues to be a net favorable position.

Borrowings

On January 5, 2018, we entered into a credit agreement providing for committed credit facilities in the amount of $1.2 billion U.S. dollars, which amended and restated in its entirety our credit agreement dated June 23, 2015 and replaced committed facilities in the amount of $725 million. The 2018 credit facility consists of a $650 million U.S. dollar term loan (the term loan) and a multicurrency revolving line of credit (the revolver) with a principal amount of up to $500 million. The revolver also contains a $300 million standby letter of credit sub-facility and a $50 million swingline sub-facility. Both the term loan and the revolver mature on January 5, 2023 and can be repaid without penalty. Amounts repaid on the term loan may not be reborrowed and amounts borrowed under the revolver during the credit facility term may be repaid and reborrowed until the revolver's maturity, at which time all outstanding loans together with all accrued and unpaid interest must be repaid. During the quarter ended June 30, 2019, we made debt prepayments on the term loan in excess of required principal payments and intend to make additional payments in excess of our current portion of debt in the next year.

For further description of our borrowing, refer to Item 1: "Financial Statements (Unaudited), Note 6: Debt."

43

For a description of our letters of credit and performance bonds, and the amounts available for additional borrowings or letters of credit under our lines of credit, including the revolver that is part of our credit facility, refer to Item 1: "Financial Statements (Unaudited), Note 11: Commitments and Contingencies."

Silver Spring Networks, Inc. Acquisition

As part of the acquisition of SSNI, we announced an integration plan to obtain approximately $50 million of annualized savings by the end of 2020. For the six months ended June 30, 2019, we have paid out $19.0 million and we have approximately $30 million to $40 million of estimated cash payments remaining on the integration plan, the majority of which is expected to be paid out in the next 12 months. We have recognized $9.2 million and $20.8 million of the acquisition and integration related expenses during the three and six months ended June 30, 2019.

Restructuring

For the six months ended June 30, 2019, we have paid out a net $10.9 million related to the restructuring projects. As of June 30, 2019, $65.7 million was accrued for restructuring projects, of which $24.4 million is expected to be paid over the next 12 months.

For further details regarding our restructuring activities, refer to Item 1: "Financial Statements (Unaudited), Note 12: Restructuring."

Stock Repurchase Authorization

On March 14, 2019, Itron's Board of Directors authorized the Company to repurchase up to $50 million of our common stock over a 12-month period (the 2019 Stock Repurchase Program). Following the announcement of the program and through June 30, 2019, we repurchased 529,396 shares at an average share price of $47.22 (including commissions) for a total of $25 million. The remaining amount authorized for repurchase under the 2019 Stock Repurchase Program is $25 million. In accordance with the terms of our 5% senior notes indenture maturing January 15, 2026, we are limited to a total of $25 million in stock repurchases in 2019. As we have already met that threshold, we will not repurchase any more shares for the remainder of 2019.

Other Liquidity Considerations

We have tax credits and net operating loss carryforwards in various jurisdictions that are available to reduce cash taxes. However, utilization of tax credits and net operating losses are limited in certain jurisdictions. Based on current projections, we expect to pay, net of refunds, approximately $1 million in state taxes and $17 million in local and foreign taxes during 2019. We do not expect to pay any U.S. federal taxes. For a discussion of our tax provision and unrecognized tax benefits, see Item 1: "Financial Statements (Unaudited), Note 10: Income Taxes."

At June 30, 2019, we are under examination by certain tax authorities for the 2010 to 2017 tax years. The material jurisdictions where we are subject to examination for the 2010 to 2017 tax years include, among others, the United States, France, Germany, Italy, Brazil, and the United Kingdom. No material changes have occurred to previously disclosed assessments. We believe we have appropriately accrued for the expected outcome of all tax matters and do not currently anticipate that the ultimate resolution of these examinations will have a material adverse effect on our financial condition, future results of operations, or liquidity.

As of June 30, 2019, there was $31.9 million of cash and short-term investments held by certain foreign subsidiaries in which we are permanently reinvested for tax purposes. As a result of recent changes in U.S. tax legislation, any repatriation in the future would not result in U.S. federal income tax. Accordingly, there is no provision for U.S. deferred taxes on this cash. If this cash were repatriated to fund U.S. operations, additional withholding tax costs may be incurred. Tax is only one of the many factors that we consider in the management of global cash. Accordingly, the amount of taxes that we would need to accrue and pay to repatriate foreign cash could vary significantly.

In several of our consolidated international subsidiaries, we have joint venture partners, who are minority shareholders. Although these entities are not wholly-owned by Itron, Inc., we consolidate them because we have a greater than 50% ownership interest and/or because we exercise control over the operations. The noncontrolling interest balance in our Consolidated Balance Sheets represents the proportional share of the equity of the joint venture entities, which is attributable to the minority shareholders. At June 30, 2019, $5.9 million of our consolidated cash balance is held in our joint venture entities. As a result, the minority shareholders of these entities have rights to their proportional share of this cash balance, and there may be limitations on our ability to repatriate cash to the United States from these entities.

General Liquidity Overview

We expect to grow through a combination of internal new research and development, licensing technology from and to others, distribution agreements, partnering arrangements, and acquisitions of technology or other companies. We expect these activities to be funded with existing cash, cash flow from operations, borrowings, or the sale of common stock or other securities. We believe existing sources of liquidity will be sufficient to fund our existing operations and obligations for the next 12 months and into the foreseeable future, but offer no assurances. Our liquidity could be affected by the stability of the electricity, gas, and water industries,

44

competitive pressures, our dependence on certain key vendors and components, changes in estimated liabilities for product warranties and/or litigation, future business combinations, capital market fluctuations, international risks, and other factors described under "Risk Factors" within Item 1A of Part I of our 2018 Annual Report, as well as "Quantitative and Qualitative Disclosures About Market Risk" within Item 3 of Part I included in this Quarterly Report on Form 10-Q.

Contingencies

Refer to Item 1: "Financial Statements (Unaudited), Note 11: Commitments and Contingencies."

Critical Accounting Estimates and Policies

The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Changes in these estimates and assumptions are considered reasonably possible and may have a material effect on our consolidated financial statements and thus actual results could differ from the amounts reported and disclosed herein. Our critical accounting policies that require the use of estimates and assumptions were discussed in detail in the 2018 Annual Report and have not changed materially, with the exception of the adoption of Accounting Standards Codification (ASC) 842, Leases.

Refer to Item 1: "Financial Statements (Unaudited), Note 1: Summary of Significant Accounting Policies" included in this Quarterly Report on Form 10-Q for further disclosures regarding new accounting pronouncements.

45

Non-GAAP Measures

The accompanying schedule contains non-GAAP financial measures. To supplement our consolidated financial statements, which are prepared in accordance with GAAP, we use certain non-GAAP financial measures, including non-GAAP operating expense, non-GAAP operating income, non-GAAP net income, non-GAAP diluted EPS, adjusted EBITDA, constant currency and free cash flow. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP, and other companies may define such measures differently. We use these non-GAAP financial measures for financial and operational decision making and/or as a means for determining executive compensation. Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance and ability to service debt by excluding certain expenses that may not be indicative of our recurring core operational results. These non-GAAP financial measures facilitate management's internal comparisons to our historical performance as well as comparisons to our competitors' operating results. Our executive compensation plans exclude non-cash charges related to amortization of intangibles and certain discrete cash and non-cash charges such as acquisition and integration related expenses, restructuring charges or goodwill impairment charges. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. We believe these non-GAAP financial measures are useful to investors because they provide greater transparency with respect to key metrics used by management in its financial and operational decision making and because they are used by our institutional investors and the analyst community to analyze the health of our business.

Non-GAAP operating expenses and non-GAAP operating income – We define non-GAAP operating expenses as operating expenses excluding certain expenses related to the amortization of intangible assets, restructuring, corporate transition costs, acquisition and integration, and goodwill impairment. We define non-GAAP operating income as operating income excluding the expenses related to the amortization of intangible assets, restructuring, corporate transition costs, acquisition and integration, and goodwill impairment. Acquisition and integration related expenses include costs, which are incurred to affect and integrate business combinations, such as professional fees, certain employee retention and salaries related to integration, severances, contract terminations, travel costs related to knowledge transfer, system conversion costs, and asset impairment charges. We consider these non-GAAP financial measures to be useful metrics for management and investors because they exclude the effect of expenses that are related to acquisitions and restructuring projects. By excluding these expenses, we believe that it is easier for management and investors to compare our financial results over multiple periods and analyze trends in our operations. For example, in certain periods expenses related to amortization of intangible assets may decrease, which would improve GAAP operating margins, yet the improvement in GAAP operating margins due to this lower expense is not necessarily reflective of an improvement in our core business. There are some limitations related to the use of non-GAAP operating expenses and non-GAAP operating income versus operating expenses and operating income calculated in accordance with GAAP. We compensate for these limitations by providing specific information about the GAAP amounts excluded from non-GAAP operating expense and non-GAAP operating income and evaluating non-GAAP operating expense and non-GAAP operating income together with GAAP operating expense and GAAP operating income.

Non-GAAP net income and non-GAAP diluted EPS – We define non-GAAP net income as net income attributable to Itron, Inc. excluding the expenses associated with amortization of intangible assets, amortization of debt placement fees, restructuring, corporate transition costs, acquisition and integration, goodwill impairment, and the tax effect of excluding these expenses. We define non-GAAP diluted EPS as non-GAAP net income divided by the weighted average shares, on a diluted basis, outstanding during each period. We consider these financial measures to be useful metrics for management and investors for the same reasons that we use non-GAAP operating income. The same limitations described above regarding our use of non-GAAP operating income apply to our use of non-GAAP net income and non-GAAP diluted EPS. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP measures and evaluating non-GAAP net income and non-GAAP diluted EPS together with GAAP net income attributable to Itron, Inc. and GAAP diluted EPS.

For interim periods, beginning the first quarter of 2019, the budgeted annual effective tax rate (AETR) is used, adjusted for any discrete items, as defined in ASC 740 - Income Taxes. The budgeted AETR is determined at the beginning of the fiscal year. The AETR is revised throughout the year based on changes to our full-year forecast. If the revised AETR increases or decreases by 200 basis points or more from the budgeted AETR due to changes in the full-year forecast during the year, the revised AETR is used in place of the budgeted AETR beginning with the quarter the 200 basis point threshold is exceeded and going forward for all subsequent interim quarters in the year. We continue to assess the AETR based on latest forecast throughout the year and use the most recent AETR anytime it increases or decreases by 200 basis points or more from the prior interim period.

Adjusted EBITDA – We define adjusted EBITDA as net income (a) minus interest income, (b) plus interest expense, depreciation and amortization of intangible assets, restructuring, acquisition and integration related expense, corporate transition cost, goodwill impairment and (c) excluding income tax provision or benefit. Management uses adjusted EBITDA as a performance measure for executive compensation. A limitation to using adjusted EBITDA is that it does not represent the total increase or decrease in the

46

cash balance for the period and the measure includes some non-cash items and excludes other non-cash items. Additionally, the items that we exclude in our calculation of adjusted EBITDA may differ from the items that our peer companies exclude when they report their results. We compensate for these limitations by providing a reconciliation of this measure to GAAP net income.

Free cash flow – We define free cash flow as cash provided by (used in) operating activities less cash used for acquisitions of property, plant and equipment. We believe free cash flow provides investors with a relevant measure of liquidity and a useful basis for assessing our ability to fund our operations and repay our debt. The same limitations described above regarding our use of adjusted EBITDA apply to our use of free cash flow. We compensate for these limitations by providing specific information regarding the GAAP amounts and reconciling to free cash flow.

Constant currency – We refer to the impact of foreign currency exchange rate fluctuations in our discussions of financial results, which references the differences between the foreign currency exchange rates used to translate operating results from local currencies into U.S. dollars for financial reporting purposes. We also use the term "constant currency," which represents financial results adjusted to exclude changes in foreign currency exchange rates as compared with the rates in the comparable prior year period. We calculate the "constant currency" change as the difference between the current period results and the comparable prior period's results restated using current period foreign currency exchange rates.

⁽¹⁾  The income tax effect of non-GAAP adjustments is calculated using the statutory tax rates for the relevant jurisdictions, provided no valuation allowance exists. If a valuation allowance exists, there is no tax impact to the non-GAAP adjustment. Effective for the first quarter of 2019, we use the budgeted annual effective tax rate (AETR) for interim periods, with adjustments for discrete items, as defined in ASC 740 - Income Taxes. This method impacts interim periods only and does not impact full year tax results, as any difference between the budgeted or revised AETR and the actual AETR for non-GAAP adjustments would be recognized in the fourth quarter of the year. If the revised methodology had been applied in the second quarter of 2018, non-GAAP net income would have increased by $1.7 million to $22.2 million, and diluted non-GAAP EPS would have increased by $0.05 to $0.56. If the methodology had been applied in the six months ended 2018 non-GAAP net income would have increased by $5.8 million to $31.3 million, and diluted non-GAAP EPS would have increased by $0.15 to $0.79.

Item 3:    Quantitative and Qualitative Disclosures about Market Risk

In the normal course of business, we are exposed to interest rate and foreign currency exchange rate risks that could impact our financial position and results of operations. As part of our risk management strategy, we may use derivative financial instruments to hedge certain foreign currency and interest rate exposures. Our objective is to offset gains and losses resulting from these exposures with losses and gains on the derivative contracts used to hedge them, therefore reducing the impact of volatility on earnings or protecting the fair values of assets and liabilities. We use derivative contracts only to manage existing underlying exposures. Accordingly, we do not use derivative contracts for trading or speculative purposes.

Interest Rate Risk

We are exposed to interest rate risk through our variable rate debt instruments. In October 2015, we entered into an interest rate swap, which is effective from August 31, 2016 to June 23, 2020, and converts $214 million of our LIBOR-based debt from a floating LIBOR interest rate to a fixed interest rate of 1.42% (excluding the applicable margin on the debt). The notional balance will amortize to maturity at the same rate as required minimum payments on our term loan. At June 30, 2019, our LIBOR-based debt balance was $615.6 million.

In November 2015, we entered into three interest rate cap contracts with a total notional amount of $100 million. The interest rate cap contracts expire on June 23, 2020 and were entered into in order to limit our interest rate exposure on $100 million of our variable LIBOR-based debt up to 2.00%. In the event LIBOR is higher than 2.00%, we will pay interest at the capped rate of 2.00% with respect to the $100 million notional amount of such agreements. The interest rate cap contracts do not include the effect of the applicable margin.

In April 2018, we entered into a cross-currency swap, which converts $56.0 million of floating rate U.S. Dollar denominated debt into fixed rate euro denominated debt. This cross-currency swap matures on April 30, 2021 and mitigates the risk associated with fluctuations in interest and currency rates impacting cash flows related to a U.S. Dollar denominated debt in a euro functional currency entity.

49

The table below provides information about our financial instruments that are sensitive to changes in interest rates and the scheduled minimum repayment of principal and the weighted average interest rates at June 30, 2019. Weighted average variable rates in the table are based on implied forward rates in the Reuters U.S. dollar yield curve as of June 30, 2019 and our estimated leverage ratio, which determines our additional interest rate margin at June 30, 2019.

Dollars in thousands	2019			2020			2021			2022			2023			2024		Total		Fair Value

Weighted average interest rate (receive) Floating - LIBOR	2.02		%	1.58		%	1.46		%

Based on a sensitivity analysis as of June 30, 2019, we estimate that, if market interest rates average one percentage point higher in 2019 than in the table above, our financial results in 2019 would not be materially impacted.

We continually monitor and assess our interest rate risk and may institute additional derivative instruments to manage such risk in the future.

Foreign Currency Exchange Rate Risk

We conduct business in a number of countries. As a result, approximately half of our revenues and operating expenses are denominated in foreign currencies, which expose our account balances to movements in foreign currency exchange rates that could have a material effect on our financial results. Our primary foreign currency exposure relates to non-U.S. dollar denominated transactions in our international subsidiary operations, the most significant of which is the euro. Revenues denominated in functional currencies other than the U.S. dollar were 36% and 37% of total revenues for the three and six months ended June 30, 2019 compared with 42% and 43% for the same respective period in 2018.

We are also exposed to foreign exchange risk when we enter into non-functional currency transactions, both intercompany and third party. At each period-end, non-functional currency monetary assets and liabilities are revalued with the change recognized to other income and expense. We enter into monthly foreign exchange forward contracts, which are not designated for hedge accounting, with the intent to reduce earnings volatility associated with currency exposures. As of June 30, 2019, a total of 48 contracts were offsetting our exposures from the Euro, Pound Sterling, Indonesian Rupiah, Chinese Yuan, Canadian Dollar, Indian Rupee and various other currencies, with notional amounts ranging from $131,000 to $9.4 million. Based on a sensitivity analysis as of June 30, 2019, we estimate that, if foreign currency exchange rates average ten percentage points higher in 2019 for these financial instruments, our financial results in 2019 would not be materially impacted.

50

In future periods, we may use additional derivative contracts to protect against foreign currency exchange rate risks.

Item 4:    Controls and Procedures

Evaluation of disclosure controls and procedures

An evaluation was performed under the supervision and with the participation of our Company's management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e)) under the Securities Exchange Act of 1934 as amended. Based on that evaluation, the Company's management, including the Chief Executive Officer and Chief Financial Officer, concluded that as of June 30, 2019, the Company's disclosure controls and procedures were effective to ensure the information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Changes in internal controls over financial reporting

In the ordinary course of business, we review our system of internal control over financial reporting and make changes to our applications and processes to improve such controls and increase efficiency, while ensuring that we maintain an effective internal control environment. Changes may include such activities as implementing new, more efficient applications and automating manual processes. We are continuing to upgrade our global enterprise resource software applications at certain of our locations outside of the United States. We will continue to upgrade our financial applications in stages, and we believe the related changes to processes and internal controls will allow us to be more efficient and further enhance our internal control over financial reporting.

Except for these changes, there have been no other changes in our internal control over financial reporting during the three months ended June 30, 2019 that materially affected, or are reasonably likely to materially affect, internal control over financial reporting.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Financial Statement Preparation

The condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q are unaudited and reflect entries necessary for the fair presentation of the Consolidated Statements of Operations, the Consolidated Statements of Comprehensive Income (Loss), Consolidated Statements of Equity, and Consolidated Statements of Cash Flows for the three and six months ended June 30, 2019 and 2018, and the Consolidated Balance Sheets as of June 30, 2019 and December 31, 2018, of Itron, Inc. and its subsidiaries. All entries required for the fair presentation of the financial statements are of a normal recurring nature, except as disclosed. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the full year or for any other period.

Certain information and notes normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim results. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2018 filed with the SEC in our Annual Report on Form 10-K on February 28, 2019 (2018 Annual Report). There have been no significant changes in financial statement preparation or significant accounting policies since December 31, 2018 other than the adoption of Accounting Standards Codification (ASC) 842, Leases.

Restricted Cash and Cash Equivalents

Cash and cash equivalents that are contractually restricted from operating use are classified as restricted cash and cash equivalents.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows:

In thousands	June 30, 2019		December 31, 2018		June 30, 2018
Cash and cash equivalents	$	135,736	$	120,221	$	162,882
Restricted cash included in other current assets	51		51		51
Long-term restricted cash	2,066		2,056		2,109
Total cash, cash equivalents, and restricted cash	$	137,853	$	122,328	$	165,042

Subsequent to the issuance of our June 30, 2018 consolidated financial statements, we determined $150 million of proceeds from borrowings and payments on debt, originally transacted during the first quarter of 2018, had been improperly netted within the financing activities section of the Consolidated Statements of Cash Flows for the first three quarters of 2018. We corrected this presentation for the 2018 Annual Report on Form 10‑K. The accompanying Consolidated Statement of Cash Flows for the six months ended June 30, 2018 has been revised from amounts previously reported to separately present the $150 million of proceeds from borrowings and the payments on debt. We assessed the significance of the misstatement and concluded that it was not material to any prior periods. There were no changes to net cash flows from operating, investing, or financing activities as a result of this change.

Leases

We determine if an arrangement is a lease at inception. A lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment), and (2) the customer has the right to control the use of the identified asset.

Operating leases are included in operating lease right-of-use ("ROU") assets, other current liabilities, and operating lease liabilities on our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, other current liabilities, and other long-term obligations on our Consolidated Balance Sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit rate when readily determinable. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Operating lease ROU asset also includes any lease payments made and excludes lease incentives received and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements, which include lease and nonlease components. For each of our existing asset classes, we have elected the practical expedient to account for the lease and nonlease components as a single lease component when the nonlease components are fixed.

We have not elected to utilize the short-term lease exemption for any leased asset class. All leases with a lease term that is greater than one month will be subject to recognition and measurement on the balance sheet.

Lease expense for variable lease payments, where the timing or amount of the payment is not fixed, are recognized when the obligation is incurred. Variable lease payments generally arise in our net lease arrangements where executory and other lease-related costs are billed to Itron when incurred by the lessor.

Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) (ASU 2016-02), which required substantially all leases be recognized by lessees on their balance sheet as a right-of-use asset and corresponding lease liability, including leases previously accounted for as operating leases. The new standard also resulted in enhanced quantitative and qualitative disclosures, including significant judgments made by management, to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing leases. The standard required modified retrospective adoption and was effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. We adopted ASC 842, as amended, on January 1, 2019, and it resulted in an increase to operating lease right-of-use assets, other current liabilities, and operating lease liabilities of $74.6 million, $14.5 million, and $61.5 million, respectively, and a decrease in other current assets and other long-term obligations of $1.5 million and $2.9 million, respectively.

In August 2018, the FASB issued ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments also require us to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. We adopted ASU 2018-15 as of January 1, 2019, and it did not have a material impact on our financial condition, results of operations, or cash flows.

In October 2018, the FASB issued ASU 2018-16, Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. We adopted this standard on January 1, 2019, and it did not materially impact our consolidated financial statements. This update establishes OIS rates based on SOFR as an approved benchmark interest rate in addition to existing rates such as the LIBOR swap rate.

Recent Accounting Standards Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) (ASU 2016-13), which replaces the incurred loss impairment methodology in current GAAP with a methodology based on expected credit losses. This estimate of expected credit losses uses a broader range of reasonable and supportable information. This change will result in earlier recognition of credit losses. ASU 2016-13, as amended, will be effective as of January 1, 2020 for us. We are currently evaluating the impact of this standard on our consolidated financial statements, as well as our accounting policies, processes, and systems.

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), which amends the disclosure requirements under ASC 820, Fair Value Measurements. ASU 2018-13 is effective for us beginning with our interim financial reports for the first quarter of 2020. We are currently evaluating the impact

this standard will have on our consolidated financial statement disclosures related to assets and liabilities subject to fair value measurement.

In August 2018, the FASB issued ASU 2018-14, Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14), which amends the disclosure requirements under ASC 715-20, Compensation-Retirement Benefits-Defined Benefit Plans. ASU 2018-14 is effective for our financial reporting in 2020. We are currently evaluating the impact this standard will have on our financial statement disclosures for our defined benefit plans.

Earnings Per Share

The following table sets forth the computation of basic and diluted earnings (loss) per share (EPS):

	Three Months Ended June 30,				Six Months Ended June 30,

Weighted average common shares outstanding - Basic	39,389		39,243		39,523		39,095
Dilutive effect of stock-based awards	297		546		352		—
Weighted average common shares outstanding - Diluted	39,686		39,789		39,875		39,095
Net income (loss) per common share - Basic	$	0.49	$	0.07	$	0.44	$	(3.66	)
Net income (loss) per common share - Diluted	$	0.49	$	0.07	$	0.44	$	(3.66	)

Stock-based Awards

For stock-based awards, the dilutive effect is calculated using the treasury stock method. Under this method, the dilutive effect is computed as if the awards were exercised at the beginning of the period (or at time of issuance, if later) and assumes the related proceeds were used to repurchase common stock at the average market price during the period. Related proceeds include the amount the employee must pay upon exercise and the future compensation cost associated with the stock award. Approximately 0.5 million and 0.6 million stock-based awards were excluded from the calculation of diluted EPS for the three and six months ended June 30, 2019 because they were anti-dilutive. Approximately 0.7 million and 1.1 million stock-based awards were excluded from the calculation of diluted EPS for the three and six months ended June 30, 2018 because they were anti-dilutive. These stock-based awards could be dilutive in future periods.

On January 5, 2018, we completed our acquisition of Silver Spring Networks, Inc. (SSNI) by purchasing 100% of the voting stock. Acquired intangible assets include in-process research and development (IPR&D), which is not amortized until such time as the associated development projects are completed. Of these projects, $3.1 million were completed during the first half of 2019 and are included in core-developed technology. Acquired intangible liabilities reflect the present value of the projected cash outflows for an existing contract where remaining costs are expected to exceed projected revenues.

Estimated future annual amortization (accretion) is as follows:

Silver Spring Networks, Inc. Acquisition

On January 5, 2018, we completed the acquisition of SSNI by purchasing 100% of SSNI's outstanding stock. The acquisition was financed through incremental borrowings and cash on hand. Refer to "Note 6: Debt" for further discussion of our debt. SSNI provided smart network and data platform solutions for electricity, gas, water and smart cities including advanced metering, distribution automation, demand-side management, and street lights.

The fair values for the identified trademarks and core-developed technology intangible assets were estimated using the relief from royalty method. The fair value of customer contract and relationship were estimated using the income approach. The IPR&D was valued utilizing the replacement cost method. These consolidated financial statements should be read in conjunction with the audited financial statements and notes included in our 2018 Annual Report.

The purchase price of SSNI was $809.2 million, which is net of $97.8 million of acquired cash and cash equivalents. Of the total consideration, $802.5 million was paid in cash. The remaining $6.7 million relates to the fair value of pre-acquisition service for replacement awards of unvested SSNI options and restricted stock unit awards with an Itron equivalent award. We allocated the purchase price to the assets acquired and liabilities assumed based on estimated fair value assessments. During the three months ended March 31, 2019, we recognized additional contract assets totaling $8.0 million and additional deferred tax liabilities of $2.0 million, for a net reduction in goodwill of $6.0 million. As of the first quarter of 2019, the measurement period for the acquisition of SSNI was complete, and any further adjustments to assets acquired or liabilities assumed are recognized through the Consolidated Statement of Operations.

Credit Facility

On January 5, 2018, we entered into a credit agreement providing for committed credit facilities in the amount of $1.2 billion U.S. dollars (the 2018 credit facility), which amended and restated in its entirety our credit agreement dated June 23, 2015 and replaced committed facilities in the amount of $725 million. The 2018 credit facility consists of a $650 million U.S. dollar term loan (the term loan) and a multicurrency revolving line of credit (the revolver) with a principal amount of up to $500 million. The revolver also contains a $300 million standby letter of credit sub-facility and a $50 million swingline sub-facility. Both the term loan and the revolver mature on January 5, 2023 and can be repaid without penalty. Amounts repaid on the term loan may not be reborrowed and amounts borrowed under the revolver may be repaid and reborrowed until the revolver's maturity, at which time all outstanding loans together with all accrued and unpaid interest must be repaid. Amounts not borrowed under the revolver are subject to a commitment fee, which is paid in arrears on the last day of each fiscal quarter, ranging from 0.18% to 0.35% per annum depending on our total leverage ratio as of the most recently ended fiscal quarter.

The 2018 credit facility permits us and certain of our foreign subsidiaries to borrow in U.S. dollars, euros, British pounds, or, with lender approval, other currencies readily convertible into U.S. dollars. All obligations under the 2018 credit facility are guaranteed by Itron, Inc. and material U.S. domestic subsidiaries and are secured by a pledge of substantially all of the assets of Itron, Inc. and material U.S. domestic subsidiaries, including a pledge of their related assets. This includes a pledge of 100% of the capital stock of material U.S. domestic subsidiaries and up to 66% of the voting stock (100% of the non-voting stock) of first-tier foreign subsidiaries. In addition, the obligations of any foreign subsidiary who is a foreign borrower, as defined by the 2018 credit facility, are guaranteed by the foreign subsidiary and by its direct and indirect foreign parents. The 2018 credit facility includes debt covenants, which contain certain financial thresholds and place certain restrictions on the incurrence of debt, investments, and the issuance of dividends. We were in compliance with the debt covenants under the 2018 credit facility at June 30, 2019.

Under the 2018 credit facility, we elect applicable market interest rates for both the term loan and any outstanding revolving loans. We also pay an applicable margin, which is based on our total leverage ratio as defined in the credit agreement. The applicable rates per annum may be based on either: (1) the LIBOR rate or EURIBOR rate (subject to a floor of 0%), plus an applicable margin, or (2) the Alternate Base Rate, plus an applicable margin. The Alternate Base Rate election is equal to the greatest of three rates: (i) the prime rate, (ii) the Federal Reserve effective rate plus 0.50%, or (iii) one-month LIBOR plus 1.00%. At June 30, 2019, the interest rate for both the term loan and revolver was 4.16%, which includes the LIBOR rate plus a margin of 1.75%.

Senior Notes

On December 22, 2017 and January 19, 2018, we issued $300 million and $100 million, respectively, of aggregate principal amount of 5.00% senior notes maturing January 15, 2026 (Notes). The proceeds were used to refinance existing indebtedness related to the acquisition of SSNI, pay related fees and expenses, and for general corporate purposes. Interest on the Notes is payable semi-annually in arrears on January 15 and July 15, commencing on July 15, 2018. The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our subsidiaries that guarantee the 2018 credit facility.

Prior to maturity we may redeem some or all of the Notes, together with accrued and unpaid interest, if any, plus a "make-whole" premium. On or after January 15, 2021, we may redeem some or all of the Notes at any time at declining redemption prices equal to 102.50% beginning on January 15, 2021, 101.25% beginning on January 15, 2022 and 100.00% beginning on January 15, 2023 and thereafter to the applicable redemption date. In addition, before January 15, 2021, and subject to certain conditions, we may redeem up to 35% of the aggregate principal amount of Notes with the net proceeds of certain equity offerings at 105.00% of the principal amount thereof to the date of redemption; provided that (i) at least 65% of the aggregate principal amount of Notes remains outstanding after such redemption and (ii) the redemption occurs within 60 days of the closing of any such equity offering.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

As part of our risk management strategy, we use derivative instruments to hedge certain foreign currency and interest rate exposures. Refer to "Note 13: Shareholder's Equity" and "Note 14: Fair Values of Financial Instruments" for additional disclosures on our derivative instruments.

The fair values of our derivative instruments are determined using the income approach and significant other observable inputs (also known as "Level 2"). We have used observable market inputs based on the type of derivative and the nature of the underlying instrument. The key inputs include interest rate yield curves (swap rates and futures) and foreign exchange spot and forward rates, all of which are available in an active market. We have utilized the mid-market pricing convention for these inputs. We include, as a discount to the derivative asset, the effect of our counterparty credit risk based on current published credit default swap rates when the net fair value of our derivative instruments is in a net asset position. We consider our own nonperformance risk when the net fair value of our derivative instruments is in a net liability position by discounting our derivative liabilities to reflect the potential credit risk to our counterparty through applying a current market indicative credit spread to all cash flows.

The fair values of our derivative instruments were as follows:

		Fair Value
Derivative Assets	Balance Sheet Location	June 30, 2019		December 31, 2018
Derivatives designated as hedging instruments under Subtopic 815-20		In thousands

Total asset derivatives		$	4,726	$	6,525
Derivative Liabilities

Foreign exchange forward contracts	Other current liabilities	$	70	$	337

The changes in accumulated other comprehensive income (loss) (AOCI), net of tax, for our derivative and nonderivative hedging instruments designated as hedging instruments, net of tax, were as follows:

In thousands	2019			2018
Net unrealized loss on hedging instruments at January 1,	$	(13,179	)	$	(13,414	)
Unrealized gain (loss) on hedging instruments	998			4,078
Realized (gains) losses reclassified into net income (loss)	(2,497		)	(2,423		)
Net unrealized loss on hedging instruments at June 30,	$	(14,678	)	$	(11,759	)

Reclassification of amounts related to hedging instruments are included in interest expense in the Consolidated Statements of Operations for the periods ended June 30, 2019 and 2018. Included in the net unrealized gain (loss) on hedging instruments at

June 30, 2019 and 2018 is a loss of $14.4 million, net of tax, related to our nonderivative net investment hedge, which terminated in 2011. This loss on our net investment hedge will remain in AOCI until earnings are impacted by a sale or liquidation of the associated foreign operation.

A summary of the effect of netting arrangements on our financial position related to the offsetting of our recognized derivative assets and liabilities under master netting arrangements or similar agreements is as follows:

Offsetting of Derivative Assets	Gross Amounts of Recognized Assets Presented in the Consolidated Balance Sheets		Gross Amounts Not Offset in the Consolidated Balance Sheets
In thousands			Derivative Financial Instruments			Cash Collateral Received		Net Amount
June 30, 2019	$	4,726	$	(69	)	$	—	$	4,657
December 31, 2018	$	6,525	$	(103	)	$	—	$	6,422

Offsetting of Derivative Liabilities	Gross Amounts of Recognized Liabilities Presented in the Consolidated Balance Sheets		Gross Amounts Not Offset in the Consolidated Balance Sheets

December 31, 2018	$	337	$	(103	)	$	—	$	234

Our derivative assets and liabilities subject to netting arrangements consist of foreign exchange forwards and options and interest rate contracts with six counterparties at June 30, 2019 and five counterparties at December 31, 2018. No derivative asset or liability balance with any of our counterparties was individually significant at June 30, 2019 or December 31, 2018. Our derivative contracts with each of these counterparties exist under agreements that provide for the net settlement of all contracts through a single payment in a single currency in the event of default. We have no pledges of cash collateral against our obligations, and we have not received pledges of cash collateral from our counterparties under the associated derivative contracts.

Cash Flow Hedges

As a result of our floating rate debt, we are exposed to variability in our cash flows from changes in the applicable interest rate index. We enter into interest rate caps and swaps to reduce the variability of cash flows from increases in the LIBOR based borrowing rates on our floating rate credit facility. These instruments do not protect us from changes to the applicable margin under our credit facility. At June 30, 2019, our LIBOR-based debt balance was $615.6 million.

In October 2015, we entered into an interest rate swap, which is effective from August 31, 2016 to June 23, 2020, and converts $214 million of our LIBOR based debt from a floating LIBOR interest rate to a fixed interest rate of 1.42% (excluding the applicable margin on the debt). The notional balance will amortize to maturity at the same rate as required minimum payments on our term loan. Changes in the fair value of the interest rate swap are recognized as a component of other comprehensive income (OCI) and are recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedge are recognized as an adjustment to interest expense along with the earnings effect of the hedged item. The amount of net gains expected to be reclassified into earnings in the next 12 months is $0.7 million.

In November 2015, we entered into three interest rate cap contracts with a total notional amount of $100 million at a cost of $1.7 million. The interest rate cap contracts expire on June 23, 2020 and were entered into in order to limit our interest rate exposure on $100 million of our variable LIBOR based debt up to 2.00%. In the event LIBOR is higher than 2.00%, we will pay interest at the capped rate of 2.00% with respect to the $100 million notional amount of such agreements. As of December 31, 2016, due to the accelerated revolver payments from surplus cash, we elected to de-designate two of the interest rate cap contracts as cash flow hedges and discontinued the use of cash flow hedge accounting. The amounts recognized in AOCI from de-designated interest rate cap contracts were maintained in AOCI as the forecasted transactions were still probable to occur, and subsequent changes in fair value were recognized within interest expense. In April 2018, due to increases in our total LIBOR-based debt, we elected to re-designate the two interest rate cap contracts as cash flow hedges. Future changes in the fair value of these instruments will be recognized as a component of OCI, and these changes together with amounts previously maintained in AOCI will be recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedge are recognized as an adjustment to interest expense along with the earnings effect of the hedged item. The amount of net losses expected to be reclassified into earnings for all interest rate cap contracts in the next 12 months is $0.6 million.

In April 2018, we entered into a cross-currency swap, which converts $56.0 million of floating LIBOR-based U.S. Dollar denominated debt into 1.38% fixed rate euro denominated debt. This cross-currency swap matures on April 30, 2021 and mitigates the risk associated with fluctuations in currency rates impacting cash flows related to U.S. Dollar denominated debt in a euro functional currency entity. Changes in the fair value of the cross-currency swap are recognized as a component of OCI and will be recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedge are recognized as an adjustment to interest expense along with the earnings effect of the hedged item. The amount of net gains expected to be reclassified into earnings in the next 12 months is $1.3 million.

As a result of our forecasted purchases in non-functional currency, we are exposed to foreign exchange risk. We hedge portions of our forecasted foreign currency inventory purchases. During January 2019, we entered into foreign exchange option contracts for a total notional amount of $72 million at a cost of $1.3 million. The contracts will mature ratably through the year with final maturity in October 2019. Changes in the fair value of the option contracts are recognized as a component of OCI and will be recognized in product cost of revenues when the hedged item affects earnings.

The before-tax effects of our accounting for derivative instruments designated as hedges on AOCI were as follows:

These reclassification amounts presented above also represent the loss (gain) recognized in net income (loss) on hedging relationships under Subtopic 815-20 on the Consolidated Statements of Operations. For the three months and six months ended June 30, 2019 and 2018, there were no amounts reclassified from AOCI as a result that a forecasted transaction is no longer probable of occurring, and no amounts excluded from effectiveness testing recognized in earnings based on changes in fair value.

Derivatives Not Designated as Hedging Relationships

We are also exposed to foreign exchange risk when we enter into non-functional currency transactions, both intercompany and third party. At each period-end, non-functional currency monetary assets and liabilities are revalued with the change recognized to other income and expense. We enter into monthly foreign exchange forward contracts, which are not designated for hedge accounting, with the intent to reduce earnings volatility associated with currency exposures. As of June 30, 2019, a total of 48 contracts were offsetting our exposures from the Euro, Pound Sterling, Indonesian Rupiah, Chinese Yuan, Canadian Dollar, Indian Rupee and various other currencies, with notional amounts ranging from $131,000 to $9.4 million.

The effect of our derivative instruments not designated as hedges on the Consolidated Statements of Operations was as follows:

Stock-Based Compensation

Stock-Based Compensation

We maintain the Second Amended and Restated 2010 Stock Incentive Plan (Stock Incentive Plan), which allows us to grant stock-based compensation awards, including stock options, restricted stock units, phantom stock, and unrestricted stock units. Under the Stock Incentive Plan, we have 12,623,538 shares of common stock reserved and authorized for issuance subject to stock splits, dividends, and other similar events. At June 30, 2019, 6,340,860 shares were available for grant under the Stock Incentive Plan. We issue new shares of common stock upon the exercise of stock options or when vesting conditions on restricted stock units are fully satisfied. These shares are subject to a fungible share provision such that the authorized share reserve is reduced by (i) one share for every one share subject to a stock option or share appreciation right granted under the Plan and (ii) 1.7 shares for every one share of common stock that was subject to an award other than an option or share appreciation right.

As part of the acquisition of SSNI, we reserved and authorized 2,880,039 shares, collectively, of Itron common stock to be issued under the Stock Incentive Plan for certain SSNI common stock awards that were converted to Itron common stock awards on January 5, 2018 (Acquisition Date) pursuant to the Agreement and Plan of Merger or were available for issuance pursuant to future awards under the Silver Spring Networks, Inc. 2012 Equity Incentive Plan (SSNI Plan). New stock-based compensation awards originally from the SSNI Plan may only be made to individuals who were not employees of Itron as of the Acquisition Date. Notwithstanding the foregoing, there is no fungible share provision for shares originally from the SSNI Plan. 

We also periodically award phantom stock units, which are settled in cash upon vesting and accounted for as liability-based awards with no impact to the shares available for grant.

In addition, we maintain the Employee Stock Purchase Plan (ESPP), for which 255,845 shares of common stock were available for future issuance at June 30, 2019.

Unrestricted stock and ESPP activity for the three and six months ended June 30, 2019 and 2018 was not significant.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We determine the interim tax benefit (provision) by applying an estimate of the annual effective tax rate to the year-to-date pretax book income (loss) and adjusting for discrete items during the reporting period, if any. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded.

Our tax rate for the three and six months ended June 30, 2019 of 30% and 42%, respectively, differed from the federal statutory rate of 21% primarily due to losses in jurisdictions for which no benefit is recognized because of valuation allowances on deferred tax assets as well as the forecasted mix of earnings in domestic and international jurisdictions.

Our tax rate for the three and six months ended June 30, 2018 of 50% and 5%, respectively, differed from the federal statutory rate of 21% primarily due to losses in jurisdictions for which no benefit is recognized because of valuation allowances on deferred tax assets as well as the forecasted mix of earnings in domestic and international jurisdictions, a benefit related to excess stock-based compensation, and uncertain tax positions.

We classify interest expense and penalties related to unrecognized tax liabilities and interest income on tax overpayments as components of income tax expense. The net interest and penalties expense recognized were as follows:

	Three Months Ended June 30,					Six Months Ended June 30,
In thousands	2019			2018		2019		2018
Net interest and penalties expense	$	(42	)	$	315	$	259	$	739

Accrued interest and penalties recognized were as follows:

In thousands	June 30, 2019		December 31, 2018
Accrued interest	$	2,383	$	2,127
Accrued penalties	1,774		1,758

Unrecognized tax benefits related to uncertain tax positions and the amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate were as follows:

In thousands	June 30, 2019		December 31, 2018
Unrecognized tax benefits related to uncertain tax positions	$	115,282	$	112,558
The amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate	113,952		111,224

At June 30, 2019, we are under examination by certain tax authorities for the 2010 to 2017 tax years. The material jurisdictions where we are subject to examination for the 2010 to 2017 tax years include, among others, the United States, France, Germany, Italy, Brazil and the United Kingdom. No material changes have occurred to previously disclosed assessments. We believe we have appropriately accrued for the expected outcome of all tax matters and do not currently anticipate that the ultimate resolution of these examinations will have a material adverse effect on our financial condition, future results of operations, or liquidity.

Based upon the timing and outcome of examinations, litigation, the impact of legislative, regulatory, and judicial developments, and the impact of these items on the statute of limitations, it is reasonably possible that the related unrecognized tax benefits could change from those recognized within the next twelve months. However, at this time, an estimate of the range of reasonably possible adjustments to the balance of unrecognized tax benefits cannot be made.

Commitments and Contingencies

Commitments and Contingencies

Guarantees and Indemnifications

We are often required to obtain standby letters of credit (LOCs) or bonds in support of our obligations for customer contracts. These standby LOCs or bonds typically provide a guarantee to the customer for future performance, which usually covers the installation phase of a contract and may, on occasion, cover the operations and maintenance phase of outsourcing contracts.

Our available lines of credit, outstanding standby LOCs, and performance bonds were as follows:

Unsecured surety bonds in force	$	102,146		$	94,365

In the event any such standby LOC or bond is called, we would be obligated to reimburse the issuer of the standby LOC or bond; however, we do not believe that any outstanding LOC or bond will be called.

We generally provide an indemnification related to the infringement of any patent, copyright, trademark, or other intellectual property right on software or equipment within our sales contracts, which indemnifies the customer from and pays the resulting costs, damages, and attorney's fees awarded against a customer with respect to such a claim provided that (a) the customer promptly notifies us in writing of the claim and (b) we have the sole control of the defense and all related settlement negotiations. We may also provide an indemnification to our customers for third-party claims resulting from damages caused by the negligence or willful misconduct of our employees/agents in connection with the performance of certain contracts. The terms of our indemnifications

generally do not limit the maximum potential payments. It is not possible to predict the maximum potential amount of future payments under these or similar agreements.

Legal Matters

We are subject to various legal proceedings and claims of which the outcomes are subject to significant uncertainty. Our policy is to assess the likelihood of any adverse judgments or outcomes related to legal matters, as well as ranges of probable losses. A determination of the amount of the liability required, if any, for these contingencies is made after an analysis of each known issue. A liability is recognized and charged to operating expense when we determine that a loss is probable and the amount can be reasonably estimated. Additionally, we would disclose contingencies for which a material loss is reasonably possible, but not probable.

Health Benefits

We are self-insured for a substantial portion of the cost of our U.S. employee group health insurance. We purchase insurance from a third party, which provides individual and aggregate stop loss protection for these costs. Each reporting period, we expense the costs of our health insurance plan including paid claims, the change in the estimate of incurred but not reported (IBNR) claims, taxes, and administrative fees (collectively, the plan costs).

Plan costs were as follows:

Restructuring

2018 Projects

On February 22, 2018, our Board of Directors approved a restructuring plan (the 2018 Projects) to continue our efforts to optimize our global supply chain and manufacturing operations, research and development, and sales and marketing organizations. We expect to substantially complete the plan by the end of 2020. Many of the affected employees are represented by unions or works councils, which require consultation, and potential restructuring projects may be subject to regulatory approval, both of which could impact the timing of charges, total expected charges, cost recognized, and planned savings in certain jurisdictions.

The total expected restructuring costs, the restructuring costs recognized, and the remaining expected restructuring costs related to the 2018 Projects are as follows:

In thousands	Total Expected Costs at June 30, 2019		Costs Recognized in Prior Periods		Costs Recognized During the Six Months Ended June 30, 2019			Expected Remaining Costs to be Recognized at June 30, 2019

2016 Projects

On September 1, 2016, we announced projects (2016 Projects) to restructure various company activities in order to improve operational efficiencies, reduce expenses and improve competitiveness. We closed or consolidated several facilities and reduced our global workforce as a result of the restructuring. The 2016 Projects were initiated during the third quarter of 2016 and were substantially completed at December 31, 2018.

During the three months ended June 30, 2019, we completed the sale of our property in Stretford, United Kingdom. A gain on sale of $5.4 million was included in restructuring expense in the Consolidated Statement of Operations.

The total expected restructuring costs, the restructuring costs recognized, and the remaining expected restructuring costs related to the 2016 Projects are as follows:

In thousands	Total Expected Costs at June 30, 2019		Costs Recognized in Prior Periods		Costs Recognized During the Six Months Ended June 30, 2019			Expected Remaining Costs to be Recognized at June 30, 2019

The following table summarizes the activity within the restructuring related balance sheet accounts for the 2018 and 2016 Projects during the six months ended June 30, 2019:

Ending balance, June 30, 2019	$	63,250		$	(5,307	)	$	7,770		$	65,713

Asset impairments are determined at the asset group level. Revenues and net operating income from the activities we have exited or will exit under the restructuring projects are not material to our operating segments or consolidated results.

Other restructuring costs include expenses for employee relocation, professional fees associated with employee severance, and costs to exit the facilities once the operations in those facilities have ceased. Costs associated with restructuring activities are generally presented in the Consolidated Statements of Operations as restructuring, except for certain costs associated with inventory write-downs, which are classified within cost of revenues, and accelerated depreciation expense, which is recognized according to the use of the asset.

The current portion of restructuring liabilities was $24.4 million and $36.0 million as of June 30, 2019 and December 31, 2018. The current portion of restructuring liabilities is classified within other current liabilities on the Consolidated Balance Sheets. The long-term portion of restructuring liabilities balances was $41.3 million and $39.6 million as of June 30, 2019 and December 31, 2018. The long-term portion of restructuring liabilities is classified within other long-term obligations on the Consolidated Balance Sheets and include severance accruals and facility exit costs.

Shareholders' Equity

Preferred Stock

We have authorized the issuance of 10 million shares of preferred stock with no par value. In the event of a liquidation, dissolution, or winding up of the affairs of the corporation, whether voluntary or involuntary, the holders of any outstanding preferred stock will be entitled to be paid a preferential amount per share to be determined by the Board of Directors prior to any payment to holders of common stock. There was no preferred stock issued or outstanding at June 30, 2019 and December 31, 2018.

Stock Repurchase Authorization

On March 14, 2019, Itron's Board of Directors authorized the Company to repurchase up to $50 million of our common stock over a 12-month period (the 2019 Stock Repurchase Program). Following the announcement of the program and through June 30, 2019, we repurchased 529,396 shares at an average share price of $47.22 (including commissions) for a total of $25 million. The remaining amount authorized for repurchase under the 2019 Stock Repurchase Program is $25 million. In accordance with the terms of our 5% senior notes indenture maturing January 15, 2026, we are limited to a total of $25 million in stock repurchases in 2019. As we have already met that threshold, we will not repurchase any more shares for the remainder of 2019.

The following methods and assumptions were used in estimating fair values:

Cash, cash equivalents, and restricted cash: Due to the liquid nature of these instruments, the carrying amount approximates fair value (Level 1).

Credit Facility - term loan and multicurrency revolving line of credit: The term loan and revolver are not traded publicly. The fair values, which are determined based upon a hypothetical market participant, are calculated using a discounted cash flow model with Level 2 inputs, including estimates of incremental borrowing rates for debt with similar terms, maturities, and credit profiles. Refer to "Note 6: Debt" for a further discussion of our debt.

Derivatives: See "Note 7: Derivative Financial Instruments" for a description of our methods and assumptions in determining the fair value of our derivatives, which were determined using Level 2 inputs.

Senior Notes: The Notes are not registered securities nor listed on any securities exchange but may be actively traded by qualified institutional buyers. The fair value is estimated using Level 1 inputs, as it is based on quoted prices for these instruments in active markets.

The fair values at June 30, 2019 and December 31, 2018 do not reflect subsequent changes in the economy, interest rates, tax rates, and other variables that may affect the determination of fair value.

Segment Reporting [Abstract]

Segment Information

Segment Information

Effective October 1, 2018, we reorganized our operational reporting segmentation from Electricity, Gas, Water, and Networks to Device Solutions, Networked Solutions, and Outcomes. Prior period segment results have been recast to conform to the new segment structure. As part of our reorganization, we actively integrated our recent acquisitions and are making investment decisions and implementing an organizational structure that aligns with these new segments. In conjunction with the rollout of our new operating segments, we unified our go-to-market strategy with a single, global, sales force that sells the full portfolio of Itron solutions, products and services. We continue to manage our research and development, service delivery, supply chain, and manufacturing operations on a worldwide basis to promote global, integrated oversight of our operations and to ensure consistency and interoperability between our operating segments.

With this reorganization, we continue to operate under the Itron brand worldwide and will manage and report under the three operating segments: Device Solutions, Networked Solutions, and Outcomes.

We have three GAAP measures of segment performance: revenues, gross profit (gross margin), and operating income (operating margin). Intersegment revenues are minimal. Certain operating expenses are allocated to the operating segments based upon internally established allocation methodologies. Corporate operating expenses, interest income, interest expense, other income (expense), and income tax provision are neither allocated to the segments, nor are they included in the measure of segment profit or loss. In addition, we allocate only certain production assets and intangible assets to our operating segments. We do not manage the performance of the segments on a balance sheet basis.

Segment Products

Device Solutions	Device Solutions - includes hardware products used for measurement, control, or sensing that do not have communications capability embedded for use with our broader Itron systems, i.e., products where Itron is not offering the complete "end-to-end" solution, but only the hardware elements. Examples of the Device Solutions portfolio include standard endpoints that are shipped without Itron communications, such as our standard gas meters, electricity IEC meters, and water meters, in addition to our heat and allocation products; communicating meters that are not a part of an Itron solution such as the Linky meter; and the implementation and installation of non-communicating devices, such as gas regulators.
Networked Solutions	Networked Solutions - includes a combination of communicating devices (smart meters, modules, endpoints, and sensors), network infrastructure, and associated application software designed and sold as a complete solution for acquiring and transporting robust application-specific data. Networked Solutions combines, into one operating segment, the majority of the assets from the recently acquired SSNI organization with our legacy Itron networking products and software and the implementation and installation of communicating devices into one segment. This includes: communicating measurement, control, or sensing endpoints such as our Itron® and OpenWay® Riva meters, Itron traditional ERT® technology, Intelis smart gas or water meters, 500G gas communication modules, 500W water communication modules; GenX networking products, network modules and interface cards; and specific network control and management software applications. Solutions supported by this segment include automated meter reading (AMR), advanced metering infrastructure (AMI), smart grid and distribution automation (DA), and smart street lighting and smart city solutions.
Outcomes	Outcomes - includes our value-added, enhanced software and services operating segment in which we manage, organize, analyze, and interpret data to improve decision making, maximize operational profitability, drive resource efficiency, and deliver results for consumers, utilities, and smart cities. Outcomes places an emphasis on delivering to Itron customers high-value, turn-key, digital experiences by leveraging the footprint of our Device Solutions and Networked Solutions segments. The revenues from these offerings are primarily recurring in nature and would include any direct management of Device Solutions, Networked Solutions, and other products on behalf of our end customers. Examples of these offerings include our meter data management and analytics offerings; our managed service solutions including network-as-a-service and platform-as-a-service, forecasting software and services; and any consulting-based engagement. Within the Outcomes segment, we also identify new business models, including performance-based contracting, to drive broader portfolio offerings across utilities and cities.

Revenues, gross profit, and operating income associated with our operating segments were as follows:

Revenues

A summary of significant net changes in the contract assets and the contract liabilities balances during the period is as follows:

	2019
In thousands	Contract liabilities, less contract assets
Beginning balance, January 1	$	102,130
Revenues recognized from beginning contract liability	(41,873		)
Increases due to amounts collected or due	184,808
Revenues recognized from current period increases	(129,074		)
Other	(9,053		)
Ending balance, June 30	$	106,938

On January 1, 2019, total contract assets were $34.3 million and total contract liabilities were $136.5 million. On June 30, 2019, total contract assets were $37.4 million and total contract liabilities were $144.4 million. The contract assets primarily relate to contracts that include a retention clause and allocations related to contracts with multiple performance obligations. The contract liabilities primarily relate to deferred revenue, such as extended warranty and maintenance cost.

Transaction price allocated to the remaining performance obligations

Total transaction price allocated to remaining performance obligations represents committed but undelivered products and services for contracts and purchase orders at period end. Twelve-month remaining performance obligations represent the portion of total transaction price allocated to remaining performance obligations that we estimate will be recognized as revenue over the next 12 months. Total transaction price allocated to remaining performance obligations is not a complete measure of our future revenues as we also receive orders where the customer may have legal termination rights but are not likely to terminate.

Total transaction price allocated to remaining performance obligations related to contracts is approximately $1.3 billion for the next twelve months and approximately $929 million for periods longer than 12 months. The total remaining performance obligations is comprised of product and service components. The service component relates primarily to maintenance agreements for which customers pay a full year's maintenance in advance, and service revenues are generally recognized over the service period. Total transaction price allocated to remaining performance obligations also includes our extended warranty contracts, for which revenue is recognized over the warranty period, and hardware, which is recognized as units are delivered. The estimate of when remaining performance obligations will be recognized requires significant judgment.

Cost to obtain a contract and cost to fulfill a contract with a customer

Cost to obtain a contract and costs to fulfill a contract are capitalized and amortized using a systematic rational approach to align with the transfer of control of underlying contracts with customers. While amounts were capitalized, they are not material.

Disaggregation of revenue

Refer to "Note 15: Segment Information" and the Consolidated Statement of Operations for disclosure regarding the disaggregation of revenue into categories, which depict how revenue and cash flows are affected by economic factors. Specifically, our operating segments, geographical regions, and categories for products, which include hardware and software and services, are presented.

Leases

We lease certain factories, service and distribution locations, offices, and equipment under operating leases. Our operating leases have initial lease terms ranging from 1 to 9 years, some of which include options to extend or renew the leases for up to 10 years. Certain lease agreements contain provisions for future rent increases. Our leases do not contain material residual value guarantees and finance leases are not material.

We have not elected the short-term lease exemption. All leases with a lease term of greater than one month are included in the following tables.

Accounting Policies [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Recent Accounting Standards Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) (ASU 2016-13), which replaces the incurred loss impairment methodology in current GAAP with a methodology based on expected credit losses. This estimate of expected credit losses uses a broader range of reasonable and supportable information. This change will result in earlier recognition of credit losses. ASU 2016-13, as amended, will be effective as of January 1, 2020 for us. We are currently evaluating the impact of this standard on our consolidated financial statements, as well as our accounting policies, processes, and systems.

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), which amends the disclosure requirements under ASC 820, Fair Value Measurements. ASU 2018-13 is effective for us beginning with our interim financial reports for the first quarter of 2020. We are currently evaluating the impact

this standard will have on our consolidated financial statement disclosures related to assets and liabilities subject to fair value measurement.

In August 2018, the FASB issued ASU 2018-14, Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14), which amends the disclosure requirements under ASC 715-20, Compensation-Retirement Benefits-Defined Benefit Plans. ASU 2018-14 is effective for our financial reporting in 2020. We are currently evaluating the impact this standard will have on our financial statement disclosures for our defined benefit plans.

Restricted Cash and Cash Equivalents

Restricted Cash and Cash Equivalents

Cash and cash equivalents that are contractually restricted from operating use are classified as restricted cash and cash equivalents.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows:

In thousands	June 30, 2019		December 31, 2018		June 30, 2018
Cash and cash equivalents	$	135,736	$	120,221	$	162,882
Restricted cash included in other current assets	51		51		51
Long-term restricted cash	2,066		2,056		2,109
Total cash, cash equivalents, and restricted cash	$	137,853	$	122,328	$	165,042

Subsequent to the issuance of our June 30, 2018 consolidated financial statements, we determined $150 million of proceeds from borrowings and payments on debt, originally transacted during the first quarter of 2018, had been improperly netted within the financing activities section of the Consolidated Statements of Cash Flows for the first three quarters of 2018. We corrected this presentation for the 2018 Annual Report on Form 10‑K. The accompanying Consolidated Statement of Cash Flows for the six months ended June 30, 2018 has been revised from amounts previously reported to separately present the $150 million of proceeds from borrowings and the payments on debt. We assessed the significance of the misstatement and concluded that it was not material to any prior periods. There were no changes to net cash flows from operating, investing, or financing activities as a result of this change.

Leases, Lessee

Leases

We determine if an arrangement is a lease at inception. A lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment), and (2) the customer has the right to control the use of the identified asset.

Operating leases are included in operating lease right-of-use ("ROU") assets, other current liabilities, and operating lease liabilities on our Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, other current liabilities, and other long-term obligations on our Consolidated Balance Sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit rate when readily determinable. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Operating lease ROU asset also includes any lease payments made and excludes lease incentives received and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements, which include lease and nonlease components. For each of our existing asset classes, we have elected the practical expedient to account for the lease and nonlease components as a single lease component when the nonlease components are fixed.

We have not elected to utilize the short-term lease exemption for any leased asset class. All leases with a lease term that is greater than one month will be subject to recognition and measurement on the balance sheet.

Lease expense for variable lease payments, where the timing or amount of the payment is not fixed, are recognized when the obligation is incurred. Variable lease payments generally arise in our net lease arrangements where executory and other lease-related costs are billed to Itron when incurred by the lessor.

New Accounting Pronouncements

Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) (ASU 2016-02), which required substantially all leases be recognized by lessees on their balance sheet as a right-of-use asset and corresponding lease liability, including leases previously accounted for as operating leases. The new standard also resulted in enhanced quantitative and qualitative disclosures, including significant judgments made by management, to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing leases. The standard required modified retrospective adoption and was effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. We adopted ASC 842, as amended, on January 1, 2019, and it resulted in an increase to operating lease right-of-use assets, other current liabilities, and operating lease liabilities of $74.6 million, $14.5 million, and $61.5 million, respectively, and a decrease in other current assets and other long-term obligations of $1.5 million and $2.9 million, respectively.

In August 2018, the FASB issued ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments also require us to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. We adopted ASU 2018-15 as of January 1, 2019, and it did not have a material impact on our financial condition, results of operations, or cash flows.

In October 2018, the FASB issued ASU 2018-16, Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. We adopted this standard on January 1, 2019, and it did not materially impact our consolidated financial statements. This update establishes OIS rates based on SOFR as an approved benchmark interest rate in addition to existing rates such as the LIBOR swap rate.
