Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies We were incorporated in the state of Washington in 1977. We provide a portfolio of solutions to utilities for the electricity, gas, and water markets throughout the world. Financial Statement Preparation The consolidated financial statements presented in this Annual Report include the Consolidated Statements of Operations, Comprehensive Income (Loss), Equity, and Cash Flows for the years ended December 31, 2015 , 2014 , and 2013 and the Consolidated Balance Sheets as of December 31, 2015 and 2014 of Itron, Inc. and its subsidiaries. Basis of Consolidation We consolidate all entities in which we have a greater than 50% ownership interest or in which we exercise control over the operations. We use the equity method of accounting for entities in which we have a 50% or less investment and exercise significant influence. Entities in which we have less than a 20% investment and where we do not exercise significant influence are accounted for under the cost method. Intercompany transactions and balances are eliminated upon consolidation. Noncontrolling Interests 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, we consolidate them because we have a greater than 50% ownership interest or because we exercise control over the operations. The noncontrolling interest balance is adjusted each period to reflect the allocation of net income (loss) and other comprehensive income (loss) attributable to the noncontrolling interests, as shown in our Consolidated Statements of Operations and our Consolidated Statements of Comprehensive Income (Loss) as well as contributions from and distributions to the owners. 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. Business Acquisitions On August 26, 2015, we completed our acquisition of 100% of Temetra Limited (Temetra) in a stock purchase. Temetra is a technology company located in Ireland and focused on meter data management and meter data collection in the water industry with a software-as-a-service business model. The acquisition strengthens our data analytics capabilities and provides us with additional cloud-based technology options for our water utility customers. The purchase price of Temetra was $9.8 million (net of $1.4 million of cash and cash equivalents acquired). Refer to Note 6 for additional information about this acquisition. Cash and Cash Equivalents We consider all highly liquid instruments with remaining maturities of three months or less at the date of acquisition to be cash equivalents. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded for invoices issued to customers in accordance with our contractual arrangements. Interest and late payment fees are minimal. Unbilled receivables are recorded when revenues are recognized upon product shipment or service delivery and invoicing occurs at a later date. We record an allowance for doubtful accounts representing our estimate of the probable losses in accounts receivable at the date of the balance sheet based on our historical experience of bad debts and our specific review of outstanding receivables. Accounts receivable are written-off against the allowance when we believe an account, or a portion thereof, is no longer collectible. Inventories Inventories are stated at the lower of cost or market using the first-in, first-out method. Cost includes raw materials and labor, plus applied direct and indirect costs. Derivative Instruments All derivative instruments, whether designated in hedging relationships or not, are recorded on the Consolidated Balance Sheets at fair value as either assets or liabilities. The components and fair values of our derivative instruments are determined using the fair value measurements of significant other observable inputs (Level 2), as defined by GAAP. The net fair value of our derivative instruments may switch between a net asset and a net liability depending on market circumstances at the end of the period. We include the effect of our counterparty credit risk based on current published credit default swap rates when the net fair value of our derivative instruments are in a net asset position and the effect of our own nonperformance risk when the net fair value of our derivative instruments are in a net liability position. For any derivative designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. For any derivative designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded as a component of other comprehensive income (loss) (OCI) and are recognized in earnings when the hedged item affects earnings. Ineffective portions of cash flow hedges are recognized in other income (expense) in the Consolidated Statements of Operations. For a hedge of a net investment, the effective portion of any unrealized gain or loss from the foreign currency revaluation of the hedging instrument is reported in OCI as a net unrealized gain or loss on derivative instruments. Upon termination of a net investment hedge, the net derivative gain/loss will remain in accumulated other comprehensive income (loss) (AOCI) until such time when earnings are impacted by a sale or liquidation of the associated operations. Ineffective portions of fair value changes or the changes in fair value of derivative instruments that do not qualify for hedging activities are recognized in other income (expense) in the Consolidated Statements of Operations. We classify cash flows from our derivative programs as cash flows from operating activities in the Consolidated Statements of Cash Flows. Derivatives are not used for trading or speculative purposes. Our derivatives are with credit worthy multinational commercial banks, with whom we have master netting agreements; however, our derivative positions are not recorded on a net basis in the Consolidated Balance Sheets. There are no credit-risk-related contingent features within our derivative instruments. Refer to Note 8 and Note 15 for further disclosures of our derivative instruments and their impact on OCI. Property, Plant, and Equipment Property, plant, and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally 30 years for buildings and improvements and three to ten years for machinery and equipment, computers and software, and furniture. Leasehold improvements are capitalized and depreciated over the term of the applicable lease, including renewable periods if reasonably assured, or over the useful lives, whichever is shorter. Construction in process represents capital expenditures incurred for assets not yet placed in service. Costs related to internally developed software and software purchased for internal uses are capitalized and are amortized over the estimated useful lives of the assets. Repair and maintenance costs are expensed as incurred. We have no major planned maintenance activities. We review long-lived assets for impairment whenever events or circumstances indicate the carrying amount of an asset group may not be recoverable. Assets held for sale are classified within other current assets in the Consolidated Balance Sheets, are reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. Gains and losses from asset disposals and impairment losses are classified within the Consolidated Statement of Operations according to the use of the asset, except those gains and losses recognized in conjunction with our restructuring activities, which are classified within restructuring expense. Prepaid Debt Fees Prepaid debt fees represent the capitalized direct costs incurred related to the issuance of debt and are recorded as noncurrent assets. These costs are amortized to interest expense over the terms of the respective borrowings, including contingent maturity or call features, using the effective interest method, or straight-line method when associated with a revolving credit facility. When debt is repaid early, the related portion of unamortized prepaid debt fees is written-off and included in interest expense. Business Combinations On the date of acquisition, the assets acquired, liabilities assumed, and any noncontrolling interests in the acquiree are recorded at their fair values. The acquiree's results of operations are also included as of the date of acquisition in our consolidated results. Intangible assets that arise from contractual/legal rights, or are capable of being separated, as well as in-process research and development (IPR&D), are measured and recorded at fair value, and amortized over the estimated useful life. IPR&D is not amortized until such time as the associated development projects are completed or terminated. If a development project is completed, the IPR&D is reclassified as a core technology intangible asset and amortized over its estimated useful life. If the development project is terminated, the recorded value of the associated IPR&D is immediately expensed. If practicable, assets acquired and liabilities assumed arising from contingencies are measured and recorded at fair value. If not practicable, such assets and liabilities are measured and recorded when it is probable that a gain or loss has occurred and the amount can be reasonably estimated. The residual balance of the purchase price, after fair value allocations to all identified assets and liabilities, represents goodwill. Acquisition-related costs are expensed as incurred. Restructuring costs associated with an acquisition are generally expensed in periods subsequent to the acquisition date, and changes in deferred tax asset valuation allowances and acquired income tax uncertainties, including penalties and interest, after the measurement period are recognized as a component of the provision for income taxes. Our acquisitions may include contingent consideration, which require us to recognize the fair value of the estimated liability at the time of the acquisition. Subsequent changes in the estimate of the amount to be paid under the contingent consideration arrangement are recognized in the Consolidated Statements of Operations. Cash payments for contingent or deferred consideration are classified within cash flows from investing activities within the Consolidated Statements of Cash Flows. Goodwill and Intangible Assets Goodwill and intangible assets may result from our business acquisitions. Intangible assets may also result from the purchase of assets and intellectual property in a transaction that does not qualify as a business combination. We use estimates, including estimates of useful lives of intangible assets, the amount and timing of related future cash flows, and fair values of the related operations, in determining the value assigned to goodwill and intangible assets. Our finite-lived intangible assets are amortized over their estimated useful lives based on estimated discounted cash flows. IPR&D is considered an indefinite-lived intangible asset and is not subject to amortization until the associated projects are completed or terminated. Finite-lived intangible assets are tested for impairment at the asset group level when events or changes in circumstances indicate the carrying value may not be recoverable. Indefinite-lived intangible assets are tested for impairment annually, when events or changes in circumstances indicate the asset may be impaired, or at the time when their useful lives are determined to be no longer indefinite. Goodwill is assigned to our reporting units based on the expected benefit from the synergies arising from each business combination, determined by using certain financial metrics, including the forecasted discounted cash flows associated with each reporting unit. Each reporting unit corresponds with its respective operating segment, effective in the fourth quarter of 2013. We test goodwill for impairment each year as of October 1, or more frequently should a significant impairment indicator occur. As part of the impairment test, we may elect to perform an assessment of qualitative factors. If this qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit, including goodwill, is less than its carrying amount, or if we elect to bypass the qualitative assessment, we would then proceed with the two-step impairment test. The impairment test involves comparing the fair values of the reporting units to their carrying amounts. If the carrying amount of a reporting unit exceeds its fair value, a second step is required to measure the goodwill impairment loss amount. This second step determines the current fair values of all assets and liabilities of the reporting unit and then compares the implied fair value of the reporting unit's goodwill to the carrying amount of that goodwill. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of the goodwill, an impairment loss is recognized in an amount equal to the excess. Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. We forecast discounted future cash flows at the reporting unit level using risk-adjusted discount rates and estimated future revenues and operating costs, which take into consideration factors such as existing backlog, expected future orders, supplier contracts, and expectations of competitive and economic environments. We also identify similar publicly traded companies and develop a correlation, referred to as a multiple, to apply to the operating results of the reporting units. These combined fair values are then reconciled to the aggregate market value of our common stock on the date of valuation, while considering a reasonable control premium. Contingencies A loss contingency is recorded if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. We evaluate, among other factors, the degree of probability of an unfavorable outcome and our ability to make a reasonable estimate of the amount of the ultimate loss. Loss contingencies that we determine to be reasonably possible, but not probable, are disclosed but not recorded. Changes in these factors and related estimates could materially affect our financial position and results of operations. Legal costs to defend against contingent liabilities are expensed as incurred. Bonus and Profit Sharing We have various employee bonus and profit sharing plans, which provide award amounts for the achievement of annual financial and nonfinancial targets. If management determines it is probable that the targets will be achieved, and the amounts can be reasonably estimated, a compensation accrual is recorded based on the proportional achievement of the financial and nonfinancial targets. Although we monitor and accrue expenses quarterly based on our progress toward the achievement of the annual targets, the actual results at the end of the year may result in awards that are significantly greater or less than the estimates made in earlier quarters. Warranty We offer standard warranties on our hardware products and large application software products. We accrue the estimated cost of new product warranties based on historical and projected product performance trends and costs during the warranty period. Testing of new products in the development stage helps identify and correct potential warranty issues prior to manufacturing. Quality control efforts during manufacturing reduce our exposure to warranty claims. When testing or quality control efforts fail to detect a fault in one of our products, we may experience an increase in warranty claims. We track warranty claims to identify potential warranty trends. If an unusual trend is noted, an additional warranty accrual would be recorded if a failure event is probable and the cost can be reasonably estimated. When new products are introduced, our process relies on historical averages of similar products until sufficient data are available. As actual experience on new products becomes available, it is used to modify the historical averages to ensure the expected warranty costs are within a range of likely outcomes. Management regularly evaluates the sufficiency of the warranty provisions and makes adjustments when necessary. The warranty allowances may fluctuate due to changes in estimates for material, labor, and other costs we may incur to repair or replace projected product failures, and we may incur additional warranty and related expenses in the future with respect to new or established products, which could adversely affect our financial position and results of operations. The long-term warranty balance includes estimated warranty claims beyond one year. Warranty expense is classified within cost of revenues. Restructuring We record a liability for costs associated with an exit or disposal activity under a restructuring project at its fair value in the period in which the liability is incurred. Employee termination benefits considered postemployment benefits are accrued when the obligation is probable and estimable, such as benefits stipulated by human resource policies and practices or statutory requirements. One-time termination benefits are expensed at the date the employee is notified. If the employee must provide future service greater than 60 days, such benefits are expensed ratably over the future service period. For contract termination costs, we record a liability upon the termination of a contract in accordance with the contract terms or the cessation of the use of the rights conveyed by the contract, whichever occurs later. Asset impairments associated with a restructuring project are determined at the asset group level. An impairment may be recorded for assets that are to be abandoned, are to be sold for less than net book value, or are held for sale in which the estimated proceeds less costs to sell are less than the net book value. We may also recognize impairment on an asset group, which is held and used, when the carrying value is not recoverable and exceeds the asset group's fair value. If an asset group is considered a business, a portion of our goodwill balance is allocated to it based on relative fair value. If the sale of an asset group under a restructuring project results in proceeds that exceed the net book value of the asset group, the resulting gain is recorded within restructuring expense in the Consolidated Statements of Operations. Defined Benefit Pension Plans We sponsor both funded and unfunded defined benefit pension plans for certain international employees. We recognize a liability for the projected benefit obligation in excess of plan assets or an asset for plan assets in excess of the projected benefit obligation. We also recognize the funded status of our defined benefit pension plans on our Consolidated Balance Sheets and recognize as a component of OCI, net of tax, the actuarial gains or losses and prior service costs or credits, if any, that arise during the period but that are not recognized as components of net periodic benefit cost. If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities, we amortize them over the employees' average future service period. Share Repurchase Plan From time to time, we may repurchase shares of Itron common stock under programs authorized by our Board of Directors. Share repurchases are made in the open market or in privately negotiated transactions and in accordance with applicable securities laws. Under applicable Washington State law, shares repurchased are retired and not displayed separately as treasury stock on the financial statements; the value of the repurchased shares is deducted from common stock. Revenue Recognition Revenues consist primarily of hardware sales, software license fees, software implementation, project management services, installation, consulting, and post-sale maintenance support. Revenues are recognized when (1) persuasive evidence of an arrangement exists, (2) delivery has occurred or services have been rendered, (3) the sales price is fixed or determinable, and (4) collectability is reasonably assured. Many of our revenue arrangements involve multiple deliverables, which combine two or more of the following: hardware, meter reading system software, installation, and/or project management services. Revenue arrangements with multiple deliverables are divided into separate units of accounting if the delivered item(s) has value to the customer on a standalone basis and delivery/performance of the undelivered item(s) is probable. The total arrangement consideration is allocated among the separate units of accounting based on their relative fair values and the applicable revenue recognition criteria considered for each unit of accounting. The amount allocable to a delivered item is limited to the amount that we are entitled to collect and that is not contingent upon the delivery/performance of additional items. Revenues for each deliverable are then recognized based on the type of deliverable, such as 1) when the products are shipped, 2) services are delivered, 3) percentage-of-completion when implementation services are essential to other deliverables in the arrangement, 4) upon receipt of customer acceptance, or 5) transfer of title and risk of loss. The majority of our revenue is recognized when products are shipped to or received by a customer or when services are provided. Hardware revenues are recognized at the time of shipment, receipt by the customer, or, if applicable, upon completion of customer acceptance provisions. Revenue from our OpenWay network software and services is recognized using the units-of-delivery method of contract accounting, as network design services and network software are essential to the functionality of the related hardware (network). This methodology results in the deferral of costs and revenues as professional services and software implementation commence prior to deployment of hardware. In the unusual instances when we are unable to reliably estimate the cost to complete a contract at its inception, we use the completed contract method of contract accounting. Revenues and costs are recognized upon substantial completion when remaining costs are insignificant and potential risks are minimal. Under contract accounting, if we estimate that the completion of a contract component (unit of accounting) will result in a loss, the loss is recognized in the period in which the loss becomes evident. We reevaluate the estimated loss through the completion of the contract component and adjust the estimated loss for changes in facts and circumstances. Many of our customer arrangements contain clauses for liquidated damages, related to the timing of delivery or milestone accomplishments, which could become material in an event of failure to meet the contractual deadlines. At the inception of the arrangement and on an ongoing basis, we evaluate if the liquidating damages represent contingent revenue and, if so, we reduce the amount of consideration allocated to the delivered products and services and record it as a reduction in revenue in the period of default. If the arrangement is subject to contract accounting, liquidated damages resulting from anticipated events of default are estimated and are accounted for as job costs in the period in which the liquidated damages are deemed probable of occurrence and are reasonably estimable. Our software customers often purchase a combination of software, service, and post contract customer support. For these types of arrangement, revenue recognition is dependent upon the availability of vendor specific objective evidence (VSOE) of fair value for any undelivered element. We determine VSOE by reference to the range of comparable standalone sales or stated renewals. We review these standalone sales or renewals on at least an annual basis. If VSOE is established for all undelivered elements in the contract, revenue is recognized for delivered elements when all other revenue recognition criteria are met. Where VSOE of all undelivered elements is not established, revenue for software and software related elements is deferred until all software products have been delivered, all software related services have commenced, and undelivered services do not include significant production, customization or modification. Revenue would be recognized over the longest period that services would be provided. Certain of our revenue arrangements include an extended or noncustomary warranty provision that covers all or a portion of a customer's replacement or repair costs beyond the standard or customary warranty period. Whether or not the extended warranty is separately priced in the arrangement, a portion of the arrangement's total consideration is allocated to this extended warranty deliverable. This revenue is deferred and recognized over the extended warranty coverage period. Extended or noncustomary warranties do not represent a significant portion of our revenue. We allocate consideration to each deliverable in an arrangement based on its relative selling price. We determine selling price using VSOE, if it exists, otherwise we use third-party evidence (TPE). We define VSOE as a median price of recent standalone transactions that are priced within a narrow range. TPE is determined based on the prices charged by our competitors for a similar deliverable when sold separately. If neither VSOE nor TPE of selling price exists for a unit of accounting, we use estimated selling price (ESP) to determine the price at which we would transact if the product or service were regularly sold by us on a standalone basis. Our determination of ESP involves a weighting of several factors based on the specific facts and circumstances of the arrangement. The factors considered include the cost to produce the deliverable, the anticipated margin on that deliverable, our ongoing pricing strategy and policies, and the characteristics of the varying markets in which the deliverable is sold. We analyze the selling prices used in our allocation of arrangement consideration on an annual basis. Selling prices are analyzed on a more frequent basis if a significant change in our business necessitates a more timely analysis or if we experience significant variances in our selling prices. Unearned revenue is recorded when a customer pays for products or services, but the criteria for revenue recognition have not been met as of the balance sheet date. Unearned revenues of $139.5 million and $134.1 million at December 31, 2015 and 2014 related primarily to professional services and software associated with our smart metering contracts, extended or noncustomary warranty, and prepaid post-contract support. Deferred costs are recorded for products or services for which ownership (typically defined as title and risk of loss) has transferred to the customer, but the criteria for revenue recognition have not been met as of the balance sheet date. Deferred costs were $56.6 million and $63.4 million at December 31, 2015 and 2014 and are recorded within other assets in the Consolidated Balance Sheets. Hardware and software post-sale maintenance support fees are recognized ratably over the life of the related service contract. Shipping and handling costs and incidental expenses billed to customers are recorded as revenue, with the associated cost charged to cost of revenues. We record sales, use, and value added taxes billed to our customers on a net basis. Product and Software Development Costs Product and software development costs primarily include employee compensation and third party contracting fees. We do not capitalize product development costs, and we do not generally capitalize software development expenses as the costs incurred are immaterial for the relatively short period of time between technological feasibility and the completion of software development. Stock-Based Compensation We measure and recognize compensation expense for all stock-based awards made to employees and directors, including stock options, stock sold pursuant to our Employee Stock Purchase Plan (ESPP), and the issuance of restricted stock units and unrestricted stock awards, based on estimated fair values. The fair value of stock options is estimated at the date of grant using the Black-Scholes option-pricing model, which includes assumptions for the dividend yield, expected volatility, risk-free interest rate, and expected term. For ESPP awards, the fair value is the difference between the market close price of our common stock on the date of purchase and the discounted purchase price. For performance-based restricted stock units and unrestricted stock awards with no market conditions, the fair value is the market close price of our common stock on the date of grant. For restricted stock units with market conditions, the fair value is estimated at the date of award using a Monte Carlo simulation model, which includes assumptions for dividend yield and expected volatility for our common stock and the common stock for companies within the Russell 3000 index, as well as the risk-free interest rate and expected term of the awards. We expense stock-based compensation at the date of grant for unrestricted stock awards. For awards with only a service condition, we expense stock-based compensation, adjusted for estimated forfeitures, using the straight-line method over the requisite service period for the entire award. For awards with performance and service conditions, if vesting is probable, we expense the stock-based compensation, adjusted for estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award. For awards with a market condition, we expense the fair value over the requisite service period. Excess tax benefits are credited to common stock when the deduction reduces cash taxes payable. When we have tax deductions in excess of the compensation cost, they are classified as financing cash inflows in the Consolidated Statements of Cash Flows. Effective October 1, 2013, we changed the terms of the ESPP to reduce the discount to 5% from the fair market value of the stock at the end of each fiscal quarter. As a result of this change, the ESPP is no longer considered compensatory, and no compensation expense is recognized for sales of our common stock to employees. Income Taxes We account for income taxes using the asset and liability method of accounting. Deferred tax assets and liabilities are recognized based upon anticipated future tax consequences, in each of the jurisdictions that we operate, attributable to: (1) the differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases; and (2) net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The calculation of our tax liabilities involves applying complex tax regulations in different tax jurisdictions to our tax positions. The effect on deferred tax assets and liabilities of a change in tax legislation and/or rates is recognized in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is not more likely than not that such assets will be realized. We do not record tax liabilities on undistributed earnings of international subsidiaries that are permanently reinvested. Foreign Exchange Our consolidated financial statements are reported in U.S. dollars. Assets and liabilities of international subsidiaries with non-U.S. dollar functional currencies are translated to U.S. dollars at the exchange rates in effect on the balance sheet date, or the last business day of the period, if applicable. Revenues and expenses for each subsidiary are translated to U.S. dollars using a weighted average rate for the relevant reporting period.

Error Corrections and Prior Period Adjustments Restatement [Line Items]
Accounting Changes and Error Corrections [Text Block]	Revision of Prior Period Financial Statements We have revised the previously reported consolidated financial statements for the years ended December 31, 2014 and 2013. Additionally, we revised the unaudited quarterly financial information for each quarter in the fiscal year ended December 31, 2014, and the first three quarters of fiscal 2015 as shown in Note 18. Adjustments related to periods prior to January 1, 2013 are reflected as an adjustment to beginning retained earnings for the year ended December 31, 2013. All impacted financial statement line items and related footnotes reflect these revisions. The revision reflects adjustments primarily related to the following areas: • Adjustments to arrangements including software where VSOE of fair value did not exist for undelivered elements and the determination of whether software was essential to the functionality of certain hardware. To correct these items, revenues and costs associated with certain software license agreements and related services were deferred and recognized ratably from the point at which customization or modification had been completed and all services have commenced, through the date services are completed or the Postcontract Customer Support term, whichever was longer. • Adjustments previously identified that were considered immaterial and had not been corrected. These adjustments have now been reflected in the periods in which the item arose.

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, future compensation cost associated with the stock award, and the amount of excess tax benefits, if any. As a result of our net losses for 2014 and 2013, there was no dilutive effect to the weighted average common shares outstanding for these years. Approximately 1.2 million , 1.4 million , and 1.4 million stock-based awards were excluded from the calculation of diluted EPS for the years ended December 31, 2015 , 2014 , and 2013 , respectively, because they were anti-dilutive. These stock-based awards could be dilutive in future periods.

No goodwill impairment was required to be recognized as the result of this quantitative analysis. In 2014, we tested the Gas and Water reporting units, in conjunction with our annual goodwill impairment testing. We used the qualitative assessment methodology, as we determined it was more likely than not that the fair values of these reporting units exceeded their respective carrying values. As a result, we did not need to perform the quantitative impairment test for the Gas and Water reporting units, and no goodwill impairments were recognized. In 2014, as a result of the impairment recognized in 2013, we concluded that it was not more likely than not that the fair value of the Electricity reporting unit exceeded its carrying value, and we therefore performed a quantitative analysis of this reporting unit. No goodwill impairment was required to be recognized as the result of this quantitative analysis. During our 2013 annual goodwill impairment test, we determined that the carrying value of the Electricity reporting unit exceeded its fair value, primarily due to delays in global smart grid projects and lower volumes and pricing pressures in certain regions in Europe and Asia/Pacific. The revised forecast for the Electricity business drove a decrease in the fair value of the reporting unit. As a result, we performed the second step of the goodwill impairment test for the Electricity reporting unit, which indicated a goodwill impairment of $174.2 million was necessary. This charge was recorded during the fourth quarter of 2013. Refer to Note 1 for a description of our reporting units and the methods used to determine the fair values of our reporting units and to determine the amount of any goodwill impairment. Temetra Acquisition On August 26, 2015, we completed our acquisition of 100% of Temetra in a stock purchase.

The 2015 credit facility consists of a $225 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 (available for immediate cash needs at a higher interest rate). Both the term loan and the revolver mature on June 23, 2020, and amounts borrowed under the revolver are classified as long-term and, during the credit facility term, may be repaid and reborrowed until the revolver's maturity, at which time the revolver will terminate, and 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 0.30% per annum depending on our total leverage ratio as of the most recently ended fiscal quarter. Amounts repaid on the term loan may not be reborrowed. The 2015 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 2015 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 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 their first-tier foreign subsidiaries. In addition, the obligations of any foreign subsidiary who is a foreign borrower, as defined by the 2015 credit facility, are guaranteed by the foreign subsidiary and by its direct and indirect foreign parents. The 2015 credit facility includes debt covenants, which contain certain financial ratio thresholds, place certain restrictions on the incurrence of debt, investments, and the issuance of dividends, and require quarterly unaudited and annual audited financial reporting. We were not in compliance with the financial reporting portion of these covenants under the 2015 credit facility at March 31, 2016. We have been granted waivers which extend the due dates for annual audited financial statements and quarterly unaudited financial statements through September 12, 2016. Scheduled principal repayments for the term loan are due quarterly in the amount of $2.8 million through June 2017, $4.2 million from September 2017 through June 2018, $5.6 million from September 2018 through March 2020, and the remainder due at maturity on June 23, 2020. The term loan may be repaid early in whole or in part, subject to certain minimum thresholds, without penalty. Required minimum principal payments on our outstanding credit facilities are as follows: Year Ending December 31, Minimum Payments (in thousands) 2016 $ 11,250 2017 14,063 2018 19,687 2019 22,500 2020 303,712 Total minimum payments on debt $ 371,212 Under the 2015 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 (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 1/2 of 1%, or (iii) one month LIBOR plus 1% . At December 31, 2015 , the interest rate for both the term loan and the USD revolver was 2.18% (the LIBOR rate plus a margin of 1.75% ), and the interest rate for the EUR revolver was 1.75% (the EURIBOR floor rate plus a margin of 1.75% ). Total credit facility repayments were as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Term loan $ 13,125 $ 26,250 $ 18,750 Multicurrency revolving line of credit (1) 49,873 76,188 55,000 Total credit facility repayments $ 62,998 $ 102,438 $ 73,750 (1) We borrowed $113.5 million , $47.7 million , and $35.0 million under the multicurrency revolving line of credit during 2015 , 2014 and 2013 , respectively. At December 31, 2015 , $151.8 million was outstanding under the 2015 credit facility revolver, and $46.6 million was utilized by outstanding standby letters of credit, resulting in $301.6 million available for additional borrowings or standby letters of credit. At December 31, 2015, $253.4 million was available for additional standby letters of credit under the letter of credit sub-facility and no amounts were outstanding under the swingline sub-facility. Upon entering into the 2015 credit facility, a portion of our unamortized prepaid debt fees, totaling $821,000 , were written off to interest expense. Prepaid debt fees of approximately $3.9 million were capitalized associated with the 2015 credit facility. Total unamortized prepaid debt fees were as follows: December 31, 2015 December 31, 2014 (in thousands) Unamortized prepaid debt fees $ 4,175 $ 2,298

General Discussion of Derivative Instruments and Hedging Activities [Abstract]
Derivative Financial Instruments [Text Block]	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 1, Note 15, and Note 16 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 are as follows: Fair Value Balance Sheet Location December 31, December 31, (in thousands) Asset Derivatives Derivatives designated as hedging instruments under ASC 815-20 Interest rate swap contracts Other long-term assets $ 1,632 $ 75 Interest rate cap contracts Other long-term assets 1,423 — Derivatives not designated as hedging instruments under ASC 815-20 Foreign exchange forward contracts Other current assets 27 107 Total asset derivatives $ 3,082 $ 182 Liability Derivatives Derivatives designated as hedging instruments under ASC 815-20 Interest rate swap contracts Other current liabilities $ 868 $ 1,317 Derivatives not designated as hedging instruments under ASC 815-20 Foreign exchange forward contracts Other current liabilities 99 236 Total liability derivatives $ 967 $ 1,553 OCI during the reporting period for our derivative and nonderivative instruments designated as hedging instruments, net of tax, was as follows: 2015 2014 2013 (in thousands) Net unrealized gain (loss) on hedging instruments at January 1, $ (15,148 ) $ (15,636 ) $ (16,069 ) Unrealized gain (loss) on derivative instruments 76 (566 ) 2 Realized (gains) losses reclassified into net income (loss) 1,010 1,054 431 Net unrealized gain (loss) on hedging instruments at December 31, $ (14,062 ) $ (15,148 ) $ (15,636 ) Reclassification of amounts related to hedging instruments are included in interest expense in the Consolidated Statements of Operations for the years ended December 31, 2015, 2014, and 2013. Included in the net unrealized loss on hedging instruments at December 31, 2015 and 2014 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 such time when earnings are impacted by a sale or liquidation of the associated foreign operation. A summary of the potential 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 Not Offset in the Consolidated Balance Sheets Gross Amounts of Recognized Assets Presented in the Consolidated Balance Sheets Derivative Financial Instruments Cash Collateral Received Net Amount (in thousands) December 31, 2015 $ 3,082 $ (565 ) $ — $ 2,517 December 31, 2014 $ 182 $ (182 ) $ — $ — Offsetting of Derivative Liabilities Gross Amounts Not Offset in the Consolidated Balance Sheets Gross Amounts of Recognized Liabilities Presented in the Consolidated Balance Sheets Derivative Financial Instruments Cash Collateral Pledged Net Amount (in thousands) December 31, 2015 $ 967 $ (565 ) $ — $ 402 December 31, 2014 $ 1,553 $ (182 ) $ — $ 1,371 Our derivative assets and liabilities subject to netting arrangements consist of foreign exchange forward and interest rate contracts with nine counterparties at December 31, 2015 and eight counterparties at December 31, 2014. No derivative asset or liability balance with any of our counterparties was individually significant at December 31, 2015 or 2014 . 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 nor have we 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 swaps to achieve a fixed rate of interest on the hedged portion of debt in order to increase our ability to forecast interest expense. The objective of these swaps is to reduce the variability of cash flows from increases in the LIBOR-based borrowing rates on our floating rate credit facility. The swaps do not protect us from changes to the applicable margin under our credit facility. In May 2012, we entered into six interest rate swaps to convert $200 million of our LIBOR based debt from a floating LIBOR interest rate to a fixed interest rate of 1.00% (excluding the applicable margin on the debt) and are effective July 31, 2013 to August 8, 2016. The cash flow hedges are expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk through the term of the hedge. Consequently, effective changes in the fair value of the interest rate swaps are recorded as a component of OCI and will be recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedges will be recognized as adjustments to interest expense. The amount of net losses expected to be reclassified into earnings in the next 12 months is $0.5 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. The cash flow hedge is expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk through the term of the hedge. Consequently, effective changes in the fair value of the interest rate swap is recorded 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 will be recognized as an adjustment to interest expense. The amount of net losses expected to be reclassified into earnings in the next 12 months is $0.3 million . At December 31, 2015 , our LIBOR-based debt balance was $314.4 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. The interest rate cap contracts do not include the effect of the applicable margin. The amount of net losses expected to be reclassified into earnings in the next 12 months is insignificant. We will continue to monitor and assess our interest rate risk and may institute additional interest rate swaps or other derivative instruments to manage such risk in the future. The before-tax effect of our cash flow derivative instruments on the Consolidated Balance Sheets and the Consolidated Statements of Operations for the years ended December 31 are as follows: Derivatives in ASC 815-20 Cash Flow Hedging Relationships Amount of Gain (Loss) Recognized in OCI on Derivative (Effective Portion) Gain (Loss) Reclassified from AOCI into Income (Effective Portion) Gain (Loss) Recognized in Income on Derivative (Ineffective Portion) Location Amount Location Amount 2015 2014 2013 2015 2014 2013 2015 2014 2013 (in thousands) (in thousands) (in thousands) Interest rate swap contracts $ 367 $ (915 ) $ (3 ) Interest expense $ (1,639 ) $ (1,704 ) $ 697 Interest expense $ — $ — $ — Interest rate cap contracts $ (244 ) $ — $ — Interest expense $ — $ — $ — Interest expense $ — $ — $ — 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 recorded to other income and expense. We enter into monthly foreign exchange forward contracts (a total of 516 contracts were entered into during the year ended December 31, 2015 ), which are not designated for hedge accounting, with the intent to reduce earnings volatility associated with currency exposures. The notional amounts of the contracts ranged from $118,000 to $23.4 million , offsetting our exposures from the euro, British pound, Canadian dollar, Australian dollar, Mexican peso and various other currencies . The effect of our foreign exchange forward derivative instruments on the Consolidated Statements of Operations for the years ended December 31 is as follows: Derivatives Not Designated as Hedging Instrument under ASC 815-20 Gain (Loss) Recognized on Derivatives in Other Income (Expense) 2015 2014 2013 (in thousands) Foreign exchange forward contracts $ (3,145 ) $ (5,248 ) $ (145 )

General Discussion of Pension and Other Postretirement Benefits [Abstract]
Defined Benefit Pension Plans [Text Block]	Defined Benefit Pension Plans We sponsor both funded and unfunded defined benefit pension plans for our international employees, primarily in Germany, France, Italy, Indonesia, Brazil, and Spain, offering death and disability, retirement, and special termination benefits. The defined benefit obligation is calculated annually by using the projected unit credit method. The measurement date for the pension plans was December 31, 2015 . 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. Our contributions for both funded and unfunded plans are paid from cash flows from our operations. We contributed $671,000 and $375,000 to the defined benefit pension plans for the years ended December 31, 2015 and 2014 , respectively. The timing of when contributions are made can vary by plan and from year to year. For 2016 , assuming that actual plan asset returns are consistent with our expected rate of return, and that interest rates remain constant, we expect to contribute approximately $403,000 to our defined benefit pension plans. The following tables set forth the components of the changes in benefit obligations and fair value of plan assets : Year Ended December 31, 2015 2014 (in thousands) Change in benefit obligation: Benefit obligation at January 1, $ 116,178 $ 102,662 Service cost 4,572 3,559 Interest cost 2,380 3,476 Actuarial (gain) loss (5,211 ) 25,838 Benefits paid (4,382 ) (5,519 ) Foreign currency exchange rate changes (12,190 ) (13,921 ) Other (1) (2,580 ) 83 Benefit obligation at December 31, $ 98,767 $ 116,178 Change in plan assets: Fair value of plan assets at January 1, $ 10,761 $ 11,680 Actual return on plan assets 159 494 Company contributions 671 375 Benefits paid (308 ) (433 ) Foreign currency exchange rate changes (1,621 ) (1,355 ) Fair value of plan assets at December 31, 9,662 10,761 Net pension plan benefit liability at fair value $ 89,105 $ 105,417 (1) Includes impact of curtailments driven by our restructuring activities. Amounts recognized on the Consolidated Balance Sheets consist of: At December 31, 2015 2014 (in thousands) Assets Plan assets in other long-term assets $ 359 $ 567 Liabilities Current portion of pension plan liability in wages and benefits payable 3,493 4,122 Long-term portion of pension plan liability 85,971 101,862 Net pension plan benefit liability $ 89,105 $ 105,417 Amounts in accumulated other comprehensive income (pre-tax) that have not yet been recognized as components of net periodic benefit costs consist of: At December 31, 2015 2014 (in thousands) Net actuarial loss $ 24,687 $ 38,462 Net prior service cost 706 1,203 Amount included in accumulated other comprehensive income $ 25,393 $ 39,665 Amounts recognized in OCI (pre-tax) are as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Net actuarial (gain) loss $ (6,894 ) $ 25,838 $ (5,881 ) Settlement/curtailment loss (336 ) (55 ) (325 ) Plan asset loss 343 129 516 Amortization of net actuarial loss (1,979 ) (572 ) (926 ) Amortization of prior service cost (59 ) (138 ) (70 ) Other (46 ) 68 (658 ) Other comprehensive (income) loss $ (8,971 ) $ 25,270 $ (7,344 ) If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities, we amortize them over the employees' average future service period. The estimated net actuarial loss and prior service cost that will be amortized from accumulated other comprehensive income into net periodic benefit cost during 2016 is $1.4 million . Net periodic pension benefit costs for our plans include the following components: Year Ended December 31, 2015 2014 2013 (in thousands) Service cost $ 4,572 $ 3,559 $ 4,205 Interest cost 2,380 3,476 3,355 Expected return on plan assets (502 ) (619 ) (635 ) Amortization of prior service costs 59 138 70 Amortization of actuarial net loss 1,979 572 926 Settlements and other 420 55 (493 ) Net periodic benefit cost $ 8,908 $ 7,181 $ 7,428 The significant actuarial weighted average assumptions used in determining the benefit obligations and net periodic benefit cost for our benefit plans are as follows: At and For The Year Ended December 31, 2015 2014 2013 Actuarial assumptions used to determine benefit obligations at end of period: Discount rate 2.59 % 2.36 % 3.76 % Expected annual rate of compensation increase 3.60 % 3.37 % 3.33 % Actuarial assumptions used to determine net periodic benefit cost for the period: Discount rate 2.36 % 3.76 % 3.36 % Expected rate of return on plan assets 5.45 % 5.40 % 3.63 % Expected annual rate of compensation increase 3.37 % 3.33 % 3.41 % We determine a discount rate for our plans based on the estimated duration of each plan’s liabilities. For our euro denominated defined benefit pension plans, which represent 94% of our benefit obligation, we use two discount rates, with consideration of the duration of the plans, using a hypothetical yield curve developed from euro-denominated AA-rated corporate bond issues, partially weighted for market value, with minimum amounts outstanding of €500 million for bonds with less than 10 years to maturity and €50 million for bonds with 10 or more years to maturity, and excluding the highest and lowest yielding 10% of bonds within each maturity group. The discount rates used, depending on the duration of the plans, were 1.50% and 2.25% . The weighted average discount rate used to measure our benefit obligations, increased by 23 basis points from December 31, 2014 to December 31, 2015 , driving a $5.2 million actuarial gain during 2015 , which is recognized in OCI. Our expected rate of return on plan assets is derived from a study of actual historic returns achieved and anticipated future long-term performance of plan assets, specific to plan investment asset category. While the study primarily gives consideration to recent insurers’ performance and historical returns, the assumption represents a long-term prospective return. The total accumulated benefit obligation for our defined benefit pension plans was $89.0 million and $104.1 million at December 31, 2015 and 2014 , respectively. We have one plan in which the fair value of plan assets exceeds the plan's accumulated benefit obligation. The total obligation and fair value of plan assets for plans with accumulated benefit obligations exceeding the fair value of plan assets are as follows: At December 31, 2015 2014 (in thousands) Projected benefit obligation $ 95,814 $ 114,150 Accumulated benefit obligation 86,534 102,146 Fair value of plan assets 6,502 8,166 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. The fair values of our plan investments by asset category are as follows: Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Unobservable Inputs (Level 3) (in thousands) December 31, 2015 Cash $ 795 $ 795 $ — Insurance funds 7,089 — 7,089 Other securities 1,778 — 1,778 Total fair value of plan assets $ 9,662 $ 795 $ 8,867 December 31, 2014 Cash $ 726 $ 726 $ — Insurance funds 7,440 — 7,440 Other securities 2,595 — 2,595 Total fair value of plan assets $ 10,761 $ 726 $ 10,035 The following tables present a reconciliation of Level 3 assets held during the years ended December 31, 2015 , and 2014 .

Share-based Compensation, Allocation and Classification in Financial Statements [Abstract]
Stock-Based Compensation [Text Block]	Stock-Based Compensation We record stock-based compensation expense for awards of stock options, stock sold pursuant to our ESPP, and the issuance of restricted stock units and unrestricted stock awards. We expense stock-based compensation primarily using the straight-line method over the requisite service period. For the years ended December 31 , stock-based compensation expense and the related tax benefit were as follows : 2015 2014 2013 (in thousands) Stock options $ 2,648 $ 2,333 $ 2,074 Restricted stock units 10,735 14,591 15,475 Unrestricted stock awards 706 936 811 ESPP — — 490 Total stock-based compensation $ 14,089 $ 17,860 $ 18,850 Related tax benefit $ 4,228 $ 4,994 $ 5,152 We issue new shares of common stock upon the exercise of stock options or when vesting conditions on restricted stock units are fully satisfied. Subject to stock splits, dividends, and other similar events, 7,473,956 shares of common stock are reserved and authorized for issuance under our 2010 Stock Incentive Plan (Stock Incentive Plan). Awards consist of stock options, restricted stock units, and unrestricted stock awards. At December 31, 2015 , 2,600,999 shares were available for grant under the Stock Incentive Plan. The Stock Incentive Plan shares are subject to a fungible share provision such that, with respect to grants made after December 31, 2009, 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 stock appreciation right. Stock Options Options to purchase our common stock are granted to certain employees, senior management, and members of our Board of Directors with an exercise price equal to the market close price of the stock on the date the Board of Directors approves the grant. Options generally become exercisable in three equal annual installments beginning one year from the date of grant and generally expire 10 years from the date of grant. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated based on our historical experience and future expectations. The fair values of stock options granted were estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: Year Ended December 31, 2015 2014 2013 Dividend yield — — — Expected volatility 34.3 % 39.3 % 38.1 % Risk-free interest rate 1.7 % 1.7 % 1.0 % Expected term (years) 5.5 5.5 5.5 Expected volatility is based on a combination of the historical volatility of our common stock and the implied volatility of our traded options for the related expected term. We believe this combined approach is reflective of current and historical market conditions and is an appropriate indicator of expected volatility. The risk-free interest rate is the rate available as of the award date on zero-coupon U.S. government issues with a term equal to the expected life of the award. The expected life is the weighted average expected life of an award based on the period of time between the date the award is granted and the estimated date the award will be fully exercised. Factors considered in estimating the expected life include historical experience of similar awards, contractual terms, vesting schedules, and expectations of future employee behavior. We have not paid dividends in the past and do not plan to pay dividends in the foreseeable future. A summary of our stock option activity for the years ended December 31 is as follows: Shares Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Life Aggregate Intrinsic Value (1) Weighted Average Grant Date Fair Value (in thousands) (years) (in thousands) Outstanding, January 1, 2013 1,137 $ 54.06 4.8 $ 3,815 Granted 129 42.76 $ 15.44 Exercised (74 ) 23.87 1,377 Expired (12 ) 49.04 Outstanding, December 31, 2013 1,180 $ 54.79 4.6 $ 1,300 Granted 160 $ 35.65 $ 13.65 Exercised (67 ) 28.03 $ 826 Forfeited (7 ) 44.06 Expired (143 ) 68.97 Outstanding, December 31, 2014 1,123 $ 51.90 4.4 $ 1,676 Granted 291 $ 35.25 $ 12.09 Exercised (24 ) 36.05 $ 26 Forfeited (17 ) 37.47 Expired (193 ) 52.17 Outstanding, December 31, 2015 1,180 $ 48.31 5.7 $ 405 Exercisable, December 31, 2015 759 $ 55.15 3.8 $ 48 Expected to vest, December 31, 2015 407 $ 36.01 8.9 $ 343 (1) The aggregate intrinsic value of outstanding stock options represents amounts that would have been received by the optionees had all in- the-money options been exercised on that date. Specifically, it is the amount by which the market value of Itron’s stock exceeded the exercise price of the outstanding in-the-money options before applicable income taxes, based on our closing stock price on the last business day of the period. The aggregate intrinsic value of stock options exercised during the period is calculated based on our stock price at the date of exercise. As of December 31, 2015 , total unrecognized stock-based compensation expense related to nonvested stock options was approximately $3.4 million , which is expected to be recognized over a weighted average period of approximately 2.2 years . Restricted Stock Units Certain employees, senior management, and members of our Board of Directors receive restricted stock units as a component of their total compensation. The fair value of a restricted stock unit is the market close price of our common stock on the date of grant. Restricted stock units generally vest over a three year period. Compensation expense, net of forfeitures, is recognized over the vesting period. Subsequent to vesting, the restricted stock units are converted into shares of our common stock on a one-for-one basis and issued to employees. We are entitled to an income tax deduction in an amount equal to the taxable income reported by the employees upon vesting of the restricted stock units. For 2013, the performance-based restricted stock units to be issued under the Performance Award Agreement are determined based on (1) our achievement of specified non-GAAP EPS targets, as established at the beginning of each year for each of the calendar years contained in the performance periods (2-year and 3-year awards) (the performance condition) and (2) our total shareholder return (TSR) relative to the TSR attained by companies that are included in the Russell 3000 Index during the performance periods (the market condition). Compensation expense, net of forfeitures, is recognized on a straight-line basis, and the units vest upon achievement of the performance condition, provided participants are employed by Itron at the end of the respective performance periods. For U.S. participants who retire during the performance period, a pro-rated number of restricted stock units (based on the number of days of employment during the performance period) immediately vest based on the attainment of the performance goals as assessed after the end of the performance period. Depending on the level of achievement of the performance condition, the actual number of shares to be earned ranges between 0% and 160% of the awards originally granted. At the end of the 2-year and 3-year performance periods, if the performance conditions are achieved at or above threshold, the number of shares earned is further adjusted by a TSR multiplier payout percentage, which ranges between 75% and 125% , based on the market condition. Therefore, based on the attainment of the performance and market conditions, the actual number of shares that vest may range from 0% to 200% of the awards originally granted. For the 2-year awards granted under the 2013 performance award, 14,433 restricted stock units became eligible for distribution at December 31, 2014 . For the 3-year awards granted under the 2013 performance award, 15,648 restricted stock units became eligible for distribution at December 31, 2015. For 2014 and 2015, the performance-based restricted stock units to be issued are determined based on the same performance and market conditions as the 2013 awards, but the performance period is 3-years. No awards became eligible for distribution since the performance periods had not concluded as of December 31, 2015. Due to the presence of the TSR multiplier market condition, we utilize a Monte Carlo valuation model to determine the fair value of the awards at the grant date. This pricing model uses multiple simulations to evaluate the probability of our achievement of various stock price levels to determine our expected TSR performance ranking. The weighted-average assumptions used to estimate the fair value of performance-based restricted stock units granted and the resulting weighted average fair-value are as follows: Year Ended December 31, 2015 2014 2013 Dividend yield — — — Expected volatility 30.1 % 32.3 % 39.1 % Risk-free interest rate 0.7 % 0.4 % 0.3 % Expected term (years) 2.1 2.0 2.5 Weighted-average fair value $ 33.48 $ 35.15 $ 45.03 Expected volatility is based on the historical volatility of our common stock for the related expected term. We believe this approach is reflective of current and historical market conditions and is an appropriate indicator of expected volatility. The risk-free interest rate is the rate available as of the award date on zero-coupon U.S. government issues with a term equal to the expected term of the award. The expected term is the term of an award based on the period of time between the date of the award and the date the award is expected to vest. The expected term assumption is based upon the plan's performance period as of the date of the award. We have not paid dividends in the past and do not plan to pay dividends in the foreseeable future. The following table summarizes restricted stock unit activity for the years ended December 31 : Number of Restricted Stock Units Weighted Average Grant Date Fair Value Aggregate Intrinsic Value (1) (in thousands) (in thousands) Outstanding, January 1, 2013 774 Granted 255 $ 42.51 Released (331 ) $ 17,983 Forfeited (40 ) Outstanding, December 31, 2013 658 Granted (2) 350 $ 35.74 Released (291 ) $ 14,402 Forfeited (35 ) Outstanding, December 31, 2014 682 Granted (3) 434 $ 35.09 Released (296 ) $ 12,204 Forfeited (64 ) Outstanding, December 31, 2015 756 Vested but not released, December 31, 2015 21 $ 746 Expected to vest, December 31, 2015 604 $ 21,860 (1) The aggregate intrinsic value is the market value of the stock, before applicable income taxes, based on the closing price on the stock release dates or at the end of the period for restricted stock units expected to vest. (2) Restricted stock units include 14,433 shares for the 2-year award under the 2013 Performance Award Agreement, which are eligible for distribution at December 31, 2014. (3) Restricted stock units include 15,648 shares for the 3-year award under the 2014 Performance Award Agreement, which are eligible for distribution at December 31, 2015. At December 31, 2015 , unrecognized compensation expense on restricted stock units was $20.6 million , which is expected to be recognized over a weighted average period of approximately 2.0 years . Unrestricted Stock Awards We grant unrestricted stock awards to members of our Board of Directors as part of their compensation. Awards are fully vested and expensed when granted. The fair value of unrestricted stock awards is the market close price of our common stock on the date of grant. The following table summarizes unrestricted stock award activity for the years ended December 31 : 2015 2014 2013 (in thousands, except per share data) Shares of unrestricted stock granted 20 24 18 Weighted average grant date fair value per share $ 35.01 $ 39.06 $ 44.12 Employee Stock Purchase Plan Under the terms of the ESPP, employees can deduct up to 10% of their regular cash compensation to purchase our common stock at a discount from the fair market value of the stock at the end of each fiscal quarter, subject to other limitations under the plan. The sale of the stock to the employees occurs at the beginning of the subsequent quarter. Effective October 1, 2013, we changed the terms of the ESPP to reduce the discount from 15% to 5% from the fair market value of the stock at the end of each fiscal quarter. As a result of this change, the ESPP will no longer be considered compensatory, and no compensation expense will be recognized for future sales of our common stock to employees. Prior to October 1, 2013, the plan was considered compensatory. The following table summarizes ESPP activity for the years ended December 31 : 2015 2014 2013 (in thousands, except per share data) Shares of stock sold to employees (1) 54 61 94 Weighted average fair value per ESPP award (2) $ — $ — $ 6.61 (1) Stock sold to employees during each fiscal quarter under the ESPP is associated with the offering period ending on the last day of the previous fiscal quarter. (2) Relating to awards associated with the offering periods during the years ended December 31 . Effective October 1, 2013, the ESPP is no longer compensatory and therefore the 2013 weighted average fair value per award is for the nine months ended September 30, 2013. At December 31, 2015 , all compensation cost associated with the ESPP had been recognized. There were approximately 392,000 shares of common stock available for future issuance under the ESPP at December 31, 2015 .

Defined Contribution, Bonus, and Profit Sharing [Abstract]
Compensation and Employee Benefit Plans [Text Block]	Defined Contribution, Bonus, and Profit Sharing Plans Defined Contribution Plans In the United States, United Kingdom, and certain other countries, we make contributions to defined contribution plans. For our U.S. employee savings plan, which represents a majority of our contribution expense, we provide a 50% match on the first 6% of the employee salary deferral, subject to statutory limitations. For our international defined contribution plans, we provide various levels of contributions, based on salary, subject to stipulated or statutory limitations. The expense for our defined contribution plans was as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Defined contribution plans expense $ 6,579 $ 7,097 $ 7,099 Bonus and Profit Sharing Plans and Awards We have employee bonus and profit sharing plans in which many of our employees participate, as well as an award program, which allows for recognition of individual employees' achievements. The bonus and profit sharing plans provide award amounts for the achievement of annual performance and financial targets. Actual bonus and profit sharing award amounts are determined at the end of the year if the performance and financial targets are met. As the bonuses are being earned during the year, we estimate a compensation accrual each quarter based on the progress towards achieving the goals, the estimated financial forecast for the year, and the probability of achieving results. Bonus and profit sharing plans and award expense was as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Bonus and profit sharing plans and award expense $ 14,192 $ 34,989 $ 18,602

Income Taxes [Text Block]	Income Taxes The following table summarizes the provision (benefit) for U.S. federal, state, and foreign taxes on income from continuing operations: Year Ended December 31, 2015 2014 2013 (in thousands) Current: Federal $ 5,033 $ 17,749 $ (356 ) State and local 1,633 775 1,044 Foreign 13,945 20,269 22,153 Total current 20,611 38,793 22,841 Deferred: Federal 3,951 (82,186 ) (14,830 ) State and local (972 ) (979 ) (2,329 ) Foreign (41,893 ) (51,646 ) (27,953 ) Total deferred (38,914 ) (134,811 ) (45,112 ) Change in valuation allowance 40,402 100,053 19,805 Total provision (benefit) for income taxes $ 22,099 $ 4,035 $ (2,466 ) The change in the valuation allowance presented above does not include the impacts of currency translation adjustments or significant intercompany transactions. Our tax provision as a percentage of income before tax was 59.6% for 2015 . Our actual tax rate differed from the 35% U.S. federal statutory tax rate due to various items. A reconciliation of income taxes at the U.S. federal statutory rate of 35% to the consolidated actual tax rate is as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Income (loss) before income taxes Domestic $ 115,526 $ 86,605 $ 20,583 Foreign (78,424 ) (104,870 ) (173,983 ) Total income (loss) before income taxes $ 37,102 $ (18,265 ) $ (153,400 ) Expected federal income tax provision (benefit) $ 12,986 $ (6,393 ) $ (53,690 ) Goodwill impairment — 119 49,730 Change in valuation allowance 40,402 100,053 19,805 Stock-based compensation 939 1,255 1,598 Foreign earnings (33,364 ) (31,544 ) (14,015 ) Tax credits (5,257 ) (91,148 ) (10,352 ) Uncertain tax positions, including interest and penalties 4,274 1,519 815 Change in tax rates 312 (20 ) 1,442 State income tax provision (benefit), net of federal effect (14 ) (1,235 ) (2,193 ) U.S. tax provision on foreign earnings 203 31,309 (245 ) Domestic production activities deduction (1,100 ) (2,312 ) (146 ) Local foreign taxes 1,450 2,295 3,212 Other, net 1,268 137 1,573 Total provision (benefit) for income taxes $ 22,099 $ 4,035 $ (2,466 ) As a result of prospective application of ASU 2015-17 (Topic 740), Balance Sheet Classification of Deferred Taxes, we have reclassified our net current deferred tax assets and liabilities to net non-current deferred tax assets and liabilities in our Consolidated Balance Sheet as of December 31, 2015. We have not retrospectively adjusted prior periods. Deferred tax assets and liabilities consist of the following: At December 31, 2015 2014 (in thousands) Deferred tax assets Loss carryforwards (1) $ 190,545 $ 188,607 Tax credits (2) 52,131 81,903 Accrued expenses 33,546 54,393 Pension plan benefits expense 16,232 19,679 Warranty reserves 25,129 19,141 Depreciation and amortization 21,499 19,111 Equity compensation 9,303 10,039 Inventory valuation 4,068 4,420 Deferred revenue 9,097 7,506 Tax effect of accumulated translation 291 — Other deferred tax assets, net 11,770 8,801 Total deferred tax assets 373,611 413,600 Valuation allowance (235,339 ) (257,728 ) Total deferred tax assets, net of valuation allowance 138,272 155,872 Deferred tax liabilities Depreciation and amortization (27,000 ) (37,061 ) Tax effect of accumulated translation — (568 ) Other deferred tax liabilities, net (3,608 ) (2,299 ) Total deferred tax liabilities (30,608 ) (39,928 ) Net deferred tax assets $ 107,664 $ 115,944 (1) For tax return purposes at December 31, 2015, we had U.S. federal loss carryforwards of $16.5 million that expire during the years 2020 and 2021. At December 31, 2015, we have net operating loss carryforwards in Luxembourg of $464.5 million that can be carried forward indefinitely, offset by a full valuation allowance. The remaining portion of the loss carryforwards are composed primarily of losses in various other foreign jurisdictions. The majority of these losses can be carried forward indefinitely. At December 31, 2015, there was a valuation allowance of $235.3 million primarily associated with foreign loss carryforwards and foreign tax credit carryforwards (discussed below). (2) For tax return purposes at December 31, 2015, we had: (1) U.S. general business credits of $21.9 million , which begin to expire in 2022; (2) U.S. alternative minimum tax credits of $2.5 million that can be carried forward indefinitely; and (3) U.S. foreign tax credits of $48.0 million, which begin to expire in 2024. At December 31, 2015, there was a valuation allowance of $31.7 million associated with foreign tax credit carryforward. We record valuation allowances to reduce deferred tax assets to the extent we believe it is more likely than not that a portion of such assets will not be realized. In making such determinations, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and our ability to carry back losses to prior years. We are required to make assumptions and judgments about potential outcomes that lie outside management’s control. Our most sensitive and critical factors are the projection, source, and character of future taxable income. Although realization is not assured, management believes it is more likely than not that deferred tax assets, net of valuation allowance, will be realized. The amount of deferred tax assets considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward periods are reduced or current tax planning strategies are not implemented. Our deferred tax assets at December 31, 2015 do not include the tax effect on $55.2 million of excess tax benefits from employee stock plan exercises. Common stock will be increased by $20.3 million when such excess tax benefits reduce cash taxes payable. We do not provide U.S. deferred taxes on temporary differences related to our foreign investments that are considered permanent in duration. These temporary differences consist primarily of undistributed foreign earnings of $26.6 million and $31.4 million at December 31, 2015 and 2014, respectively. Foreign taxes have been provided on these undistributed foreign earnings. We have not computed the unrecognized deferred income tax liability on these temporary differences. There are many assumptions that must be considered to calculate the liability, thereby making it impractical to compute at this time. We are subject to income tax in the United States and numerous foreign jurisdictions. Significant judgment is required in evaluating our tax positions and determining our provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. We establish reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when we believe that certain positions might be challenged despite our belief that our tax return positions are fully supportable. We adjust these reserves in light of changing facts and circumstances, such as the outcome of tax audits. The provision for income taxes includes the impact of reserve positions and changes to reserves that are considered appropriate. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): Unrecognized tax benefits at January 1, 2013 $ 26,433 Gross increase to positions in prior years 2,154 Gross decrease to positions in prior years (536 ) Gross increases to current period tax positions 1,670 Audit settlements — Decrease related to lapsing of statute of limitations (817 ) Effect of change in exchange rates (289 ) Unrecognized tax benefits at December 31, 2013 $ 28,615 Gross increase to positions in prior years 2,749 Gross decrease to positions in prior years (1,641 ) Gross increases to current period tax positions 3,008 Audit settlements — Decrease related to lapsing of statute of limitations (1,715 ) Effect of change in exchange rates (2,870 ) Unrecognized tax benefits at December 31, 2014 $ 28,146 Gross increase to positions in prior years 6,461 Gross decrease to positions in prior years (2,512 ) Gross increases to current period tax positions 25,741 Audit settlements — Decrease related to lapsing of statute of limitations (908 ) Effect of change in exchange rates (2,048 ) Unrecognized tax benefits at December 31, 2015 $ 54,880 At December 31, 2015 2014 2013 (in thousands) The amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate $ 53,602 $ 26,980 $ 27,694 If certain unrecognized tax benefits are recognized they would create additional deferred tax assets. These assets would require a full valuation in certain locations based upon present circumstances. We classify interest expense and penalties related to unrecognized tax benefits and interest income on tax overpayments as components of income tax expense. The net interest and penalties expense (benefit) recognized is as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Net interest and penalties expense (benefit) $ 880 $ 469 $ (1,443 ) At December 31, 2015 2014 (in thousands) Accrued interest $ 2,105 $ 1,755 Accrued penalties 2,577 2,671 At December 31, 2015, we are under examination by certain tax authorities for the 2000 to 2013 tax years. The material jurisdictions where we are subject to examination for the 2000 to 2013 tax years include, among others, the U.S., France, Germany, Italy, Brazil and the United Kingdom. No material changes have occurred to previously disclosed assessments. In April 2016, the United States Internal Revenue Service (IRS) proposed certain significant adjustments to our research and development tax credit position as part of the 2011 to 2013 tax audit. Management disagrees with the proposed adjustments on technical and factual grounds. We plan to avail ourself of all administrative, and if necessary, judicial remedies and does not expect the adjustments to ultimately result in a material change to our financial position. 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 recorded 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. We file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. We are subject to income tax examination by tax authorities in our major tax jurisdictions as follows: Tax Jurisdiction Years Subject to Audit U.S. federal Subsequent to 1999 France Subsequent to 2009 Germany Subsequent to 2010 Brazil Subsequent to 2009 United Kingdom Subsequent to 2012 Italy Subsequent to 2007

Commitments and Contingencies [Text Block]	Commitments and Contingencies Commitments Operating lease rental expense for factories, service and distribution locations, offices, and equipment was as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Rental expense $ 15,524 $ 19,178 $ 18,662 Future minimum lease payments at December 31, 2015 , under noncancelable operating leases with initial or remaining terms in excess of one year are as follows: Year Ending December 31, Minimum Payments (in thousands) 2016 $ 10,396 2017 8,600 2018 7,917 2019 5,402 2020 2,605 Beyond 2020 1,156 Future minimum lease payments $ 36,076 Rent expense is recognized straight-line over the lease term, including renewal periods if reasonably assured. We lease most of our sales and distribution locations and administrative offices. Our leases typically contain renewal options similar to the original terms with lease payments that increase based on the consumer price index. 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 bonds are as follows: At December 31, 2015 2014 (in thousands) Credit facilities (1) Multicurrency revolving line of credit $ 500,000 $ 660,000 Long-term borrowings (151,837 ) (91,469 ) Standby LOCs issued and outstanding (46,574 ) (50,399 ) Net available for additional borrowings under the multi-currency revolving line of credit $ 301,589 $ 518,132 Net available for additional standby LOCs under sub-facility 253,426 449,601 Unsecured multicurrency revolving lines of credit with various financial institutions Multicurrency revolving line of credit $ 97,989 $ 106,855 Standby LOCs issued and outstanding (31,122 ) (28,636 ) Short-term borrowings (2) (3,884 ) (4,282 ) Net available for additional borrowings and LOCs $ 62,983 $ 73,937 Unsecured surety bonds in force $ 87,558 $ 116,306 (1) Refer to Note 7 for details regarding our secured credit facilities. (2) Short-term borrowings are included in “Other current liabilities” on the Consolidated Balance Sheets. 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 recorded and charged to operating expense when we determine that a loss is probable and the amount can be reasonably estimated. Additionally, we disclose contingencies for which a material loss is reasonably possible, but not probable. In 2010 and 2011, Transdata Incorporated (Transdata) filed lawsuits against four of our customers, CenterPoint Energy (CenterPoint), Tri-County Electric Cooperative, Inc. (Tri-County), San Diego Gas & Electric Company (San Diego), and Texas-New Mexico Power Company (TNMP), as well as several other utilities, alleging infringement of three patents owned by Transdata related to the use of an antenna in a meter. Pursuant to our contractual obligations with our customers, we agreed, subject to certain exceptions, to indemnify and defend them in these lawsuits. The complaints seek unspecified damages as well as injunctive relief. CenterPoint, Tri-County, San Diego, and TNMP have denied all of the substantive allegations and filed counterclaims seeking a declaratory judgment that the patents are invalid and not infringed. In December 2011, the Judicial Panel on Multi-District Litigation consolidated all of these cases in the Western District of Oklahoma for pretrial proceedings. On April 17, 2011, the Oklahoma court stayed the litigation pending the resolution of re-examination proceedings in the United States Patent and Trademark Office (U.S. PTO). The U.S. PTO issued re-examination certificates confirming the patentability of the original claims and allowing certain new claims added by Transdata. The parties conducted a claim construction hearing on February 5, 2013 on one claim term -- “electric meter circuitry.” After initially adopting the defendants' proposed construction of the term, the Court granted Transdata's motion for reconsideration by order of June 25, 2013 and has adopted Transdata's proposed construction. On October 1, 2013, the Court issued an order construing other claim terms. Fact discovery closed on June 29, 2014. Following expert reports and depositions, both sides filed various summary judgment motions. On August 28, 2015, the Court issued orders on the motions. Among other things, the Court granted Transdata’s motion for summary judgment that certain prior art did not invalidate the claims, denied CenterPoint’s and SDG&E’s motion for summary judgment that they did not infringe certain asserted claims, and granted defendants’ motion for summary judgment on the issue of willfulness. The cases were then remanded back to the originating courts --the United States District Court for the Eastern District of Texas and the United States District Court for the Southern District of California for trial. The U.S. PTO also instituted additional re-examinations in May 2014 on all three patents but issued Notices of Intent to Issue Re-examination Certificates confirming the patentability of the challenged claims. Petitions for inter partes review, which is a procedure conducted by the Patent Trial and Appeal Board (the PTAB) of the U.S. PTO in which a party can challenge the validity of a patent, were also filed by General Electric (GE), but the PTAB found the petitions were untimely because, under the PTAB's analysis, GE was in privity with a defendant in the pending litigation (and thus was required to file within one year of the beginning of the litigation). Tri-County Electric and Texas-New Mexico Power were dismissed as a result of a settlement involving General Electric meters, leaving CenterPoint and SDG&E as the two remaining customer defendants. CenterPoint is scheduled to go to a jury trial on July 18, 2016. The SDG&E case has been stayed pending resolution of the CenterPoint trial. In addition, Transdata filed a complaint in the Eastern District of Texas on September 13, 2015 asserting that Itron infringes the three patents in the litigation above. The complaint seeks unspecified damages and injunctive relief. Itron has answered the Complaint, and denied that it is infringing any valid claims. That case has also been stayed pending resolution of the CenterPoint trial. We do not believe these matters will have a material adverse effect on our business or financial condition, although an unfavorable outcome could have a material adverse effect on our results of operations for the period in which such loss is recognized. We have reserved an amount we believe is appropriate to cover the anticipated costs related to the resolution of these matters. In Brazil, the Conselha Administravo de Defensa Economica commenced an investigation of water meter suppliers, including a subsidiary of the Company, to determine whether such suppliers participated in agreements or concerted practices to coordinate their commercial policy in Brazil. Although the Company is unable to determine the final amount of any fine at this time, we believe that we have made adequate provisions based on information available to us. Consequently, we do not believe that the actual fine and ultimate outcome of this matter will have a material adverse effect on our operations or financial condition. Itron and its subsidiaries are parties to various employment-related proceedings in jurisdictions where it does business. None of the proceedings are individually material to Itron, and we believe that we have made adequate provision such that the ultimate disposition of the proceedings will not materially affect Itron's business or financial condition.

Warranty expense is as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Total warranty expense $ 45,984 $ 9,238 $ 16,910 Warranty expense increased $36.7 million during the year ended December 31, 2015 compared with the prior year primarily due to special warranty provisions. During the second quarter of 2015, we concluded it was necessary to issue a product replacement notification to customers of our Water segment who had purchased certain communication modules manufactured between July 2013 and December 2014. We determined that a component of the modules was failing prematurely. The charge recorded for this matter during the year ended December 31, 2015 was $29.4 million . Extended Warranty A summary of changes to unearned revenue for extended warranty contracts is as follows: Year Ended December 31, 2015 2014 (in thousands) Beginning balance $ 34,138 $ 33,528 Unearned revenue for new extended warranties 2,792 3,529 Unearned revenue recognized (2,832 ) (2,655 ) Effect of change in exchange rates (444 ) (264 ) Ending balance 33,654 34,138 Less: current portion of unearned revenue for extended warranty 3,565 2,759 Long-term unearned revenue for extended warranty within Other long-term obligations $ 30,089 $ 31,379 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: Year Ended December 31, 2015 2014 2013 (in thousands) Plan costs $ 25,355 $ 23,206 $ 22,324 IBNR accrual, which is included in wages and benefits payable, was as follows: At December 31, 2015 2014 (in thousands) IBNR accrual $ 2,051 $ 1,924 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.

Restructuring and Related Activities [Abstract]
Restructuring, Impairment, and Other Activities Disclosure [Text Block]	Restructuring 2014 Projects In November 2014, our management approved restructuring projects (2014 Projects) to restructure our Electricity business and related general and administrative activities, along with certain Gas and Water activities, to improve operational efficiencies and reduce expenses. The 2014 Projects include consolidation of certain facilities and reduction of our global workforce. The improved structure will position us to meet our long-term profitability goals by better aligning global operations with markets where we can serve our customers profitably. We began implementing these projects in the fourth quarter of 2014, and we expect to substantially complete these projects by the fourth quarter of 2016. During the year ended December 31, 2015 , the total expected restructuring costs decreased by approximately $15.1 million . This includes $12.2 million in restructuring severance expense release, recognized in the year ended December 31, 2015 , resulting from employees, originally identified to be terminated, voluntarily resigning or filling vacant positions in different departments or locations, as well as the result of employee negotiations and the need to keep additional employees to meet revised forecasted demand on certain projects. In addition, we are expecting lower future legal costs associated with the termination of employees in certain locations. The favorable change in the translation impact of foreign exchange rates also lowered the expected remaining costs to be recognized. Certain aspects of the projects are subject to a variety of labor and employment laws, rules, and regulations, which could result in a delay in completing the projects at some locations. The total expected restructuring costs, the restructuring costs recognized in prior periods, the restructuring costs recognized during the year, and the remaining expected restructuring costs are as follows: Total Expected Costs at December 31, 2015 Costs Recognized in Prior Periods Costs Recognized During the Year Ended December 31, 2015 Remaining Costs to be Recognized at December 31, 2015 (in thousands) Employee severance costs $ 34,373 $ 46,524 $ (12,151 ) $ — Asset impairments & net loss on sale or disposal 8,880 7,904 976 — Other restructuring costs 6,983 17 3,912 3,054 Total $ 50,236 $ 54,445 $ (7,263 ) $ 3,054 Segments: Electricity $ 24,615 $ 28,996 $ (7,253 ) $ 2,872 Gas 11,936 12,142 (287 ) 81 Water 1,953 1,162 778 13 Corporate unallocated 11,732 12,145 (501 ) 88 Total $ 50,236 $ 54,445 $ (7,263 ) $ 3,054 Asset impairments are determined at the asset group level. Assets held for sale are classified within other current assets and are reported at the lower of the carrying amount or the fair value, less costs to sell, and are no longer depreciated or amortized. 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. During 2015, our restructuring activities related to the closure of certain facilities resulted in approximately $1.1 million of inventory write-downs. 2013 Projects In September 2013, our management approved projects (the 2013 Projects) to restructure our operations to improve profitability and increase efficiencies. We began implementing these projects in the third quarter of 2013, and we expect to substantially complete project activities by the third quarter of 2016 and begin recognizing full savings in 2017. While project activities are expected to continue through September 2016, no further costs are expected to be recognized. The 2013 Projects resulted in approximately $26.2 million of restructuring expense, which was recognized from the third quarter of 2013 through the fourth quarter of 2014. The following table summarizes the activity within the restructuring related balance sheet accounts, for the 2014 and 2013 Projects: Accrued Employee Severance Asset Impairments & Net Loss on Sale or Disposal Other Accrued Costs Total (in thousands) Beginning balance, January 1, 2015 $ 58,403 $ — $ 3,526 $ 61,929 Costs incurred (released) and charged to expense (12,151 ) 976 3,912 (7,263 ) Cash payments (14,570 ) — (4,194 ) (18,764 ) Non-cash items — (976 ) — (976 ) Effect of change in exchange rates (5,149 ) — (196 ) (5,345 ) Ending balance, December 31, 2015 $ 26,533 $ — $ 3,048 $ 29,581 The current portions of the restructuring related liability balances were $25.2 million and $48.5 million as of December 31, 2015 and 2014 , respectively. The current portion of the liability is classified within “Other current liabilities” on the Consolidated Balance Sheets. The long-term portions of the restructuring related liability related balances were $4.4 million and $13.5 million as of December 31, 2015 and 2014 , respectively. The long-term portion of the restructuring liability is classified within “Other long-term obligations” on the Consolidated Balance Sheets. The following table includes long-lived assets held and used that were measured at fair value on a nonrecurring basis as of December 31, 2015 and 2014 , and the related recognized losses for the years ended December 31, 2015 and 2014 : Net Carrying Value Fair Value Measurement (Level 3) Total Loss Recognized (in thousands) 2015 Long-lived assets held and used $ — $ — $ — 2014 Long-lived assets held and used $ 1,930 $ 1,930 $ 7,952 The fair values of the asset group included in long-lived assets held and used were determined based primarily on their appraised fair value.

Segment Reporting [Abstract]
Segment Information [Text Block]	Segment Information We operate under the Itron brand worldwide and manage and report under three operating segments, Electricity, Gas, and Water. Our Water operating segment includes both our global water and heat solutions. This structure allows each segment to develop its own go-to-market strategy, prioritize its marketing and product development requirements, and focus on its strategic investments. Our sales, marketing, and delivery functions are managed under each segment. Our product development and manufacturing operations are managed on a worldwide basis to promote a global perspective in our operations and processes and yet still maintain alignment with the segments. We have three measures of segment performance: revenue, gross profit (margin), and operating income (margin). Our operating segments have distinct products, and, therefore, intersegment revenues are minimal. Corporate operating expenses, interest income, interest expense, other income (expense), and income tax provision (benefit) are not allocated to the segments nor are 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 Electricity Standard electricity (electromechanical and electronic) meters; advanced electricity meters and communication modules; smart electricity meters; smart electricity communication modules; prepayment systems, including smart key, keypad, and smart card communication technologies; advanced systems, including handheld, mobile, and fixed network collection technologies; smart network technologies; meter data management software; knowledge application solutions; installation; implementation; and professional services, including consulting, and analysis. Gas Standard gas meters; advanced gas meters and communication modules; smart gas meters; smart gas communication modules; prepayment systems, including smart key, keypad, and smart card communication technologies; advanced systems, including handheld, mobile, and fixed network collection technologies; smart network technologies; meter data management software; knowledge application solutions installation; implementation; and professional services, including consulting, and analysis. Water Standard water and heat meters; advanced and smart water meters and communication modules; advanced systems including handheld, mobile, and fixed network collection technologies; meter data management software; knowledge application solutions; installation; implementation; and professional services, including consulting, and analysis. Revenues, gross profit, and operating income associated with our segments were as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Revenues Electricity $ 820,306 $ 771,857 $ 825,391 Gas 543,805 599,091 570,450 Water 519,422 576,668 542,184 Total Company $ 1,883,533 $ 1,947,616 $ 1,938,025 Gross profit Electricity $ 225,446 $ 200,249 $ 219,852 Gas 185,559 211,623 207,577 Water 145,680 202,178 187,339 Total Company $ 556,685 $ 614,050 $ 614,768 Operating income (loss) Electricity $ 31,104 $ (77,751 ) $ (237,279 ) Gas 67,471 76,101 82,176 Water 19,864 71,356 62,015 Corporate unallocated (65,593 ) (69,226 ) (46,775 ) Total Company 52,846 480 (139,863 ) Total other income (expense) (15,744 ) (18,745 ) (13,537 ) Income (loss) before income taxes $ 37,102 $ (18,265 ) $ (153,400 ) During the second quarter of 2015, we concluded it was necessary to issue a product replacement notification to customers of our Water segment who had purchased certain communication modules manufactured between July 2013 and December 2014. We determined that a component of the modules was failing prematurely. This resulted in a decrease to gross profit of $29.4 million for the year ended December 31, 2015 . After adjusting for the tax impact, this charge resulted in a decrease to basic and diluted earnings per share of $0.47 for the year ended December 31, 2015 . During 2014, in our Electricity segment, we revised our estimate of the cost to complete an OpenWay project in North America. This resulted in a decrease to gross profit of $15.9 million , which decreased basic and diluted earnings per share by $0.25 for the year ended December 31, 2014 . We previously recorded additional costs on this contract in 2013, which decreased gross profit by $14.5 million and decreased basic and diluted earnings per share by $0.23 for the year ended December 31, 2013 . The per share amounts are shown net of tax. For the years ended December 31, 2015 , 2014, and 2013, no single customer represented more than 10% of total Company or the Electricity, Gas or Water operating segment revenues. Revenues by region were as follows: Year Ended December 31, 2015 2014 2013 (in thousands) United States and Canada $ 997,293 $ 875,796 $ 848,951 Europe, Middle East, and Africa (EMEA) 701,301 849,841 849,464 Other 184,939 221,979 239,610 Total Company $ 1,883,533 $ 1,947,616 $ 1,938,025 Property, plant, and equipment, net, by geographic area were as follows: At December 31, 2015 2014 (in thousands) United States $ 72,179 $ 76,130 Outside United States 118,077 131,022 Total Company $ 190,256 $ 207,152 Depreciation and amortization expense associated with our segments was as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Electricity $ 35,896 $ 47,889 $ 46,510 Gas 20,288 25,706 27,671 Water 19,459 24,257 24,818 Corporate Unallocated 350 287 247 Total Company $ 75,993 $ 98,139 $ 99,246

Quarterly Results (Unaudited) [Abstract]
Quarterly Financial Information [Text Block]	Quarterly Results (Unaudited) As discussed in greater detail in Note 2 - Revision of Prior Period Financial Statements, we revised our previously issued condensed consolidated financial information for the first three quarters of fiscal 2015 and each of the quarterly periods in the year ended December 31, 2014. The revision resulted from a correction of certain errors relating to timing of revenue and cost recognition associated with contracts involving certain software products that we were unable to demonstrate VSOE of fair value for certain undelivered elements and the determination of whether software was essential to the functionality of certain hardware and certain other errors that were considered immaterial but have now been reflected in the quarterly results.

For the year ended December 31, 2015, management concluded earnings fell below the threshold at which incentive compensation was appropriate. As a result, $13.3 million of previously accrued compensation expense was reversed in the fourth quarter of 2015. During the second quarter of 2015, we concluded it was necessary to issue a product replacement notification to customers of our Water segment who had purchased certain communication modules manufactured between July 2013 and December 2014. We determined that a component of the modules was failing prematurely. As a result, we recognized a warranty charge of $23.6 million during the second quarter of 2015. In 2014, restructuring projects were approved to increase efficiency and lower our cost of manufacturing, for which we incurred costs of $54.4 million in the fourth quarter of 2014. The following tables present the effects of the adjustments made to our previously reported unaudited quarterly financial information for the first three quarters of the years ended December 31, 2015

Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Events On June 13, 2016, we received a debt covenant waiver as discussed in Note 7 - Debt. In April 2016, the United States Internal Revenue Service (IRS) proposed certain significant adjustments to our research and development tax credit position as part of the 2011 to 2013 tax audit. Management disagrees with the proposed adjustments on technical and factual grounds. We plan to avail ourself of all administrative, and if necessary, judicial remedies and do not expect the adjustments to ultimately result in a material change to our financial position.

Summary of Significant Accoun28

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Consolidation [Policy Text Block]	Basis of Consolidation We consolidate all entities in which we have a greater than 50% ownership interest or in which we exercise control over the operations. We use the equity method of accounting for entities in which we have a 50% or less investment and exercise significant influence. Entities in which we have less than a 20% investment and where we do not exercise significant influence are accounted for under the cost method. Intercompany transactions and balances are eliminated upon consolidation. Noncontrolling Interests 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, we consolidate them because we have a greater than 50% ownership interest or because we exercise control over the operations. The noncontrolling interest balance is adjusted each period to reflect the allocation of net income (loss) and other comprehensive income (loss) attributable to the noncontrolling interests, as shown in our Consolidated Statements of Operations and our Consolidated Statements of Comprehensive Income (Loss) as well as contributions from and distributions to the owners. 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.
Cash and Cash Equivalents [Policy Text Block]	Cash and Cash Equivalents We consider all highly liquid instruments with remaining maturities of three months or less at the date of acquisition to be cash equivalents.
Accounts Receivable and Allowance for Doubtful Accounts [Policy Text Block]	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded for invoices issued to customers in accordance with our contractual arrangements. Interest and late payment fees are minimal. Unbilled receivables are recorded when revenues are recognized upon product shipment or service delivery and invoicing occurs at a later date. We record an allowance for doubtful accounts representing our estimate of the probable losses in accounts receivable at the date of the balance sheet based on our historical experience of bad debts and our specific review of outstanding receivables. Accounts receivable are written-off against the allowance when we believe an account, or a portion thereof, is no longer collectible.
Inventories [Policy Text Block]	Inventories Inventories are stated at the lower of cost or market using the first-in, first-out method. Cost includes raw materials and labor, plus applied direct and indirect costs.
Derivative Instruments [Policy Text Block]	Derivative Instruments All derivative instruments, whether designated in hedging relationships or not, are recorded on the Consolidated Balance Sheets at fair value as either assets or liabilities. The components and fair values of our derivative instruments are determined using the fair value measurements of significant other observable inputs (Level 2), as defined by GAAP. The net fair value of our derivative instruments may switch between a net asset and a net liability depending on market circumstances at the end of the period. We include the effect of our counterparty credit risk based on current published credit default swap rates when the net fair value of our derivative instruments are in a net asset position and the effect of our own nonperformance risk when the net fair value of our derivative instruments are in a net liability position. For any derivative designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. For any derivative designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded as a component of other comprehensive income (loss) (OCI) and are recognized in earnings when the hedged item affects earnings. Ineffective portions of cash flow hedges are recognized in other income (expense) in the Consolidated Statements of Operations. For a hedge of a net investment, the effective portion of any unrealized gain or loss from the foreign currency revaluation of the hedging instrument is reported in OCI as a net unrealized gain or loss on derivative instruments. Upon termination of a net investment hedge, the net derivative gain/loss will remain in accumulated other comprehensive income (loss) (AOCI) until such time when earnings are impacted by a sale or liquidation of the associated operations. Ineffective portions of fair value changes or the changes in fair value of derivative instruments that do not qualify for hedging activities are recognized in other income (expense) in the Consolidated Statements of Operations. We classify cash flows from our derivative programs as cash flows from operating activities in the Consolidated Statements of Cash Flows. Derivatives are not used for trading or speculative purposes. Our derivatives are with credit worthy multinational commercial banks, with whom we have master netting agreements; however, our derivative positions are not recorded on a net basis in the Consolidated Balance Sheets. There are no credit-risk-related contingent features within our derivative instruments. Refer to Note 8 and Note 15 for further disclosures of our derivative instruments and their impact on OCI.
Property, Plant, and Equipment [Policy Text Block]	Property, Plant, and Equipment Property, plant, and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally 30 years for buildings and improvements and three to ten years for machinery and equipment, computers and software, and furniture. Leasehold improvements are capitalized and depreciated over the term of the applicable lease, including renewable periods if reasonably assured, or over the useful lives, whichever is shorter. Construction in process represents capital expenditures incurred for assets not yet placed in service. Costs related to internally developed software and software purchased for internal uses are capitalized and are amortized over the estimated useful lives of the assets. Repair and maintenance costs are expensed as incurred. We have no major planned maintenance activities. We review long-lived assets for impairment whenever events or circumstances indicate the carrying amount of an asset group may not be recoverable. Assets held for sale are classified within other current assets in the Consolidated Balance Sheets, are reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. Gains and losses from asset disposals and impairment losses are classified within the Consolidated Statement of Operations according to the use of the asset, except those gains and losses recognized in conjunction with our restructuring activities, which are classified within restructuring expense.
Prepaid Debt Fees [Policy Text Block]	Prepaid Debt Fees Prepaid debt fees represent the capitalized direct costs incurred related to the issuance of debt and are recorded as noncurrent assets. These costs are amortized to interest expense over the terms of the respective borrowings, including contingent maturity or call features, using the effective interest method, or straight-line method when associated with a revolving credit facility. When debt is repaid early, the related portion of unamortized prepaid debt fees is written-off and included in interest expense.
Business Combinations [Policy Text Block]	Business Combinations On the date of acquisition, the assets acquired, liabilities assumed, and any noncontrolling interests in the acquiree are recorded at their fair values. The acquiree's results of operations are also included as of the date of acquisition in our consolidated results. Intangible assets that arise from contractual/legal rights, or are capable of being separated, as well as in-process research and development (IPR&D), are measured and recorded at fair value, and amortized over the estimated useful life. IPR&D is not amortized until such time as the associated development projects are completed or terminated. If a development project is completed, the IPR&D is reclassified as a core technology intangible asset and amortized over its estimated useful life. If the development project is terminated, the recorded value of the associated IPR&D is immediately expensed. If practicable, assets acquired and liabilities assumed arising from contingencies are measured and recorded at fair value. If not practicable, such assets and liabilities are measured and recorded when it is probable that a gain or loss has occurred and the amount can be reasonably estimated. The residual balance of the purchase price, after fair value allocations to all identified assets and liabilities, represents goodwill. Acquisition-related costs are expensed as incurred. Restructuring costs associated with an acquisition are generally expensed in periods subsequent to the acquisition date, and changes in deferred tax asset valuation allowances and acquired income tax uncertainties, including penalties and interest, after the measurement period are recognized as a component of the provision for income taxes. Our acquisitions may include contingent consideration, which require us to recognize the fair value of the estimated liability at the time of the acquisition. Subsequent changes in the estimate of the amount to be paid under the contingent consideration arrangement are recognized in the Consolidated Statements of Operations. Cash payments for contingent or deferred consideration are classified within cash flows from investing activities within the Consolidated Statements of Cash Flows.
Goodwill and Intangible Assets [Policy Text Block]	Goodwill and Intangible Assets Goodwill and intangible assets may result from our business acquisitions. Intangible assets may also result from the purchase of assets and intellectual property in a transaction that does not qualify as a business combination. We use estimates, including estimates of useful lives of intangible assets, the amount and timing of related future cash flows, and fair values of the related operations, in determining the value assigned to goodwill and intangible assets. Our finite-lived intangible assets are amortized over their estimated useful lives based on estimated discounted cash flows. IPR&D is considered an indefinite-lived intangible asset and is not subject to amortization until the associated projects are completed or terminated. Finite-lived intangible assets are tested for impairment at the asset group level when events or changes in circumstances indicate the carrying value may not be recoverable. Indefinite-lived intangible assets are tested for impairment annually, when events or changes in circumstances indicate the asset may be impaired, or at the time when their useful lives are determined to be no longer indefinite. Goodwill is assigned to our reporting units based on the expected benefit from the synergies arising from each business combination, determined by using certain financial metrics, including the forecasted discounted cash flows associated with each reporting unit. Each reporting unit corresponds with its respective operating segment, effective in the fourth quarter of 2013. We test goodwill for impairment each year as of October 1, or more frequently should a significant impairment indicator occur. As part of the impairment test, we may elect to perform an assessment of qualitative factors. If this qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit, including goodwill, is less than its carrying amount, or if we elect to bypass the qualitative assessment, we would then proceed with the two-step impairment test. The impairment test involves comparing the fair values of the reporting units to their carrying amounts. If the carrying amount of a reporting unit exceeds its fair value, a second step is required to measure the goodwill impairment loss amount. This second step determines the current fair values of all assets and liabilities of the reporting unit and then compares the implied fair value of the reporting unit's goodwill to the carrying amount of that goodwill. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of the goodwill, an impairment loss is recognized in an amount equal to the excess. Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. We forecast discounted future cash flows at the reporting unit level using risk-adjusted discount rates and estimated future revenues and operating costs, which take into consideration factors such as existing backlog, expected future orders, supplier contracts, and expectations of competitive and economic environments. We also identify similar publicly traded companies and develop a correlation, referred to as a multiple, to apply to the operating results of the reporting units. These combined fair values are then reconciled to the aggregate market value of our common stock on the date of valuation, while considering a reasonable control premium.
Contingencies [Policy Text Block]	Contingencies A loss contingency is recorded if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. We evaluate, among other factors, the degree of probability of an unfavorable outcome and our ability to make a reasonable estimate of the amount of the ultimate loss. Loss contingencies that we determine to be reasonably possible, but not probable, are disclosed but not recorded. Changes in these factors and related estimates could materially affect our financial position and results of operations. Legal costs to defend against contingent liabilities are expensed as incurred.
Compensation Related Costs, Policy [Policy Text Block]	Bonus and Profit Sharing We have various employee bonus and profit sharing plans, which provide award amounts for the achievement of annual financial and nonfinancial targets. If management determines it is probable that the targets will be achieved, and the amounts can be reasonably estimated, a compensation accrual is recorded based on the proportional achievement of the financial and nonfinancial targets. Although we monitor and accrue expenses quarterly based on our progress toward the achievement of the annual targets, the actual results at the end of the year may result in awards that are significantly greater or less than the estimates made in earlier quarters.
Warranty [Policy Text Block]	Warranty We offer standard warranties on our hardware products and large application software products. We accrue the estimated cost of new product warranties based on historical and projected product performance trends and costs during the warranty period. Testing of new products in the development stage helps identify and correct potential warranty issues prior to manufacturing. Quality control efforts during manufacturing reduce our exposure to warranty claims. When testing or quality control efforts fail to detect a fault in one of our products, we may experience an increase in warranty claims. We track warranty claims to identify potential warranty trends. If an unusual trend is noted, an additional warranty accrual would be recorded if a failure event is probable and the cost can be reasonably estimated. When new products are introduced, our process relies on historical averages of similar products until sufficient data are available. As actual experience on new products becomes available, it is used to modify the historical averages to ensure the expected warranty costs are within a range of likely outcomes. Management regularly evaluates the sufficiency of the warranty provisions and makes adjustments when necessary. The warranty allowances may fluctuate due to changes in estimates for material, labor, and other costs we may incur to repair or replace projected product failures, and we may incur additional warranty and related expenses in the future with respect to new or established products, which could adversely affect our financial position and results of operations. The long-term warranty balance includes estimated warranty claims beyond one year. Warranty expense is classified within cost of revenues.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy	Restructuring We record a liability for costs associated with an exit or disposal activity under a restructuring project at its fair value in the period in which the liability is incurred. Employee termination benefits considered postemployment benefits are accrued when the obligation is probable and estimable, such as benefits stipulated by human resource policies and practices or statutory requirements. One-time termination benefits are expensed at the date the employee is notified. If the employee must provide future service greater than 60 days, such benefits are expensed ratably over the future service period. For contract termination costs, we record a liability upon the termination of a contract in accordance with the contract terms or the cessation of the use of the rights conveyed by the contract, whichever occurs later. Asset impairments associated with a restructuring project are determined at the asset group level. An impairment may be recorded for assets that are to be abandoned, are to be sold for less than net book value, or are held for sale in which the estimated proceeds less costs to sell are less than the net book value. We may also recognize impairment on an asset group, which is held and used, when the carrying value is not recoverable and exceeds the asset group's fair value. If an asset group is considered a business, a portion of our goodwill balance is allocated to it based on relative fair value. If the sale of an asset group under a restructuring project results in proceeds that exceed the net book value of the asset group, the resulting gain is recorded within restructuring expense in the Consolidated Statements of Operations.
Defined Benefit Pension Plans [Policy Text Block]	Defined Benefit Pension Plans We sponsor both funded and unfunded defined benefit pension plans for certain international employees. We recognize a liability for the projected benefit obligation in excess of plan assets or an asset for plan assets in excess of the projected benefit obligation. We also recognize the funded status of our defined benefit pension plans on our Consolidated Balance Sheets and recognize as a component of OCI, net of tax, the actuarial gains or losses and prior service costs or credits, if any, that arise during the period but that are not recognized as components of net periodic benefit cost. If actuarial gains and losses exceed ten percent of the greater of plan assets or plan liabilities, we amortize them over the employees' average future service period.
Share Repurchase Policy [Policy Text Block]	Share Repurchase Plan From time to time, we may repurchase shares of Itron common stock under programs authorized by our Board of Directors. Share repurchases are made in the open market or in privately negotiated transactions and in accordance with applicable securities laws. Under applicable Washington State law, shares repurchased are retired and not displayed separately as treasury stock on the financial statements; the value of the repurchased shares is deducted from common stock.
Revenue Recognition [Policy Text Block]	Revenue Recognition Revenues consist primarily of hardware sales, software license fees, software implementation, project management services, installation, consulting, and post-sale maintenance support. Revenues are recognized when (1) persuasive evidence of an arrangement exists, (2) delivery has occurred or services have been rendered, (3) the sales price is fixed or determinable, and (4) collectability is reasonably assured. Many of our revenue arrangements involve multiple deliverables, which combine two or more of the following: hardware, meter reading system software, installation, and/or project management services. Revenue arrangements with multiple deliverables are divided into separate units of accounting if the delivered item(s) has value to the customer on a standalone basis and delivery/performance of the undelivered item(s) is probable. The total arrangement consideration is allocated among the separate units of accounting based on their relative fair values and the applicable revenue recognition criteria considered for each unit of accounting. The amount allocable to a delivered item is limited to the amount that we are entitled to collect and that is not contingent upon the delivery/performance of additional items. Revenues for each deliverable are then recognized based on the type of deliverable, such as 1) when the products are shipped, 2) services are delivered, 3) percentage-of-completion when implementation services are essential to other deliverables in the arrangement, 4) upon receipt of customer acceptance, or 5) transfer of title and risk of loss. The majority of our revenue is recognized when products are shipped to or received by a customer or when services are provided. Hardware revenues are recognized at the time of shipment, receipt by the customer, or, if applicable, upon completion of customer acceptance provisions. Revenue from our OpenWay network software and services is recognized using the units-of-delivery method of contract accounting, as network design services and network software are essential to the functionality of the related hardware (network). This methodology results in the deferral of costs and revenues as professional services and software implementation commence prior to deployment of hardware. In the unusual instances when we are unable to reliably estimate the cost to complete a contract at its inception, we use the completed contract method of contract accounting. Revenues and costs are recognized upon substantial completion when remaining costs are insignificant and potential risks are minimal. Under contract accounting, if we estimate that the completion of a contract component (unit of accounting) will result in a loss, the loss is recognized in the period in which the loss becomes evident. We reevaluate the estimated loss through the completion of the contract component and adjust the estimated loss for changes in facts and circumstances. Many of our customer arrangements contain clauses for liquidated damages, related to the timing of delivery or milestone accomplishments, which could become material in an event of failure to meet the contractual deadlines. At the inception of the arrangement and on an ongoing basis, we evaluate if the liquidating damages represent contingent revenue and, if so, we reduce the amount of consideration allocated to the delivered products and services and record it as a reduction in revenue in the period of default. If the arrangement is subject to contract accounting, liquidated damages resulting from anticipated events of default are estimated and are accounted for as job costs in the period in which the liquidated damages are deemed probable of occurrence and are reasonably estimable. Our software customers often purchase a combination of software, service, and post contract customer support. For these types of arrangement, revenue recognition is dependent upon the availability of vendor specific objective evidence (VSOE) of fair value for any undelivered element. We determine VSOE by reference to the range of comparable standalone sales or stated renewals. We review these standalone sales or renewals on at least an annual basis. If VSOE is established for all undelivered elements in the contract, revenue is recognized for delivered elements when all other revenue recognition criteria are met. Where VSOE of all undelivered elements is not established, revenue for software and software related elements is deferred until all software products have been delivered, all software related services have commenced, and undelivered services do not include significant production, customization or modification. Revenue would be recognized over the longest period that services would be provided. Certain of our revenue arrangements include an extended or noncustomary warranty provision that covers all or a portion of a customer's replacement or repair costs beyond the standard or customary warranty period. Whether or not the extended warranty is separately priced in the arrangement, a portion of the arrangement's total consideration is allocated to this extended warranty deliverable. This revenue is deferred and recognized over the extended warranty coverage period. Extended or noncustomary warranties do not represent a significant portion of our revenue. We allocate consideration to each deliverable in an arrangement based on its relative selling price. We determine selling price using VSOE, if it exists, otherwise we use third-party evidence (TPE). We define VSOE as a median price of recent standalone transactions that are priced within a narrow range. TPE is determined based on the prices charged by our competitors for a similar deliverable when sold separately. If neither VSOE nor TPE of selling price exists for a unit of accounting, we use estimated selling price (ESP) to determine the price at which we would transact if the product or service were regularly sold by us on a standalone basis. Our determination of ESP involves a weighting of several factors based on the specific facts and circumstances of the arrangement. The factors considered include the cost to produce the deliverable, the anticipated margin on that deliverable, our ongoing pricing strategy and policies, and the characteristics of the varying markets in which the deliverable is sold. We analyze the selling prices used in our allocation of arrangement consideration on an annual basis. Selling prices are analyzed on a more frequent basis if a significant change in our business necessitates a more timely analysis or if we experience significant variances in our selling prices. Unearned revenue is recorded when a customer pays for products or services, but the criteria for revenue recognition have not been met as of the balance sheet date. Unearned revenues of $139.5 million and $134.1 million at December 31, 2015 and 2014 related primarily to professional services and software associated with our smart metering contracts, extended or noncustomary warranty, and prepaid post-contract support. Deferred costs are recorded for products or services for which ownership (typically defined as title and risk of loss) has transferred to the customer, but the criteria for revenue recognition have not been met as of the balance sheet date. Deferred costs were $56.6 million and $63.4 million at December 31, 2015 and 2014 and are recorded within other assets in the Consolidated Balance Sheets. Hardware and software post-sale maintenance support fees are recognized ratably over the life of the related service contract. Shipping and handling costs and incidental expenses billed to customers are recorded as revenue, with the associated cost charged to cost of revenues. We record sales, use, and value added taxes billed to our customers on a net basis.
Product and Software Development Costs [Policy Text Block]	Product and Software Development Costs Product and software development costs primarily include employee compensation and third party contracting fees. We do not capitalize product development costs, and we do not generally capitalize software development expenses as the costs incurred are immaterial for the relatively short period of time between technological feasibility and the completion of software development.
Stock-based Compensation [Policy Text Block]	Stock-Based Compensation We measure and recognize compensation expense for all stock-based awards made to employees and directors, including stock options, stock sold pursuant to our Employee Stock Purchase Plan (ESPP), and the issuance of restricted stock units and unrestricted stock awards, based on estimated fair values. The fair value of stock options is estimated at the date of grant using the Black-Scholes option-pricing model, which includes assumptions for the dividend yield, expected volatility, risk-free interest rate, and expected term. For ESPP awards, the fair value is the difference between the market close price of our common stock on the date of purchase and the discounted purchase price. For performance-based restricted stock units and unrestricted stock awards with no market conditions, the fair value is the market close price of our common stock on the date of grant. For restricted stock units with market conditions, the fair value is estimated at the date of award using a Monte Carlo simulation model, which includes assumptions for dividend yield and expected volatility for our common stock and the common stock for companies within the Russell 3000 index, as well as the risk-free interest rate and expected term of the awards. We expense stock-based compensation at the date of grant for unrestricted stock awards. For awards with only a service condition, we expense stock-based compensation, adjusted for estimated forfeitures, using the straight-line method over the requisite service period for the entire award. For awards with performance and service conditions, if vesting is probable, we expense the stock-based compensation, adjusted for estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award. For awards with a market condition, we expense the fair value over the requisite service period. Excess tax benefits are credited to common stock when the deduction reduces cash taxes payable. When we have tax deductions in excess of the compensation cost, they are classified as financing cash inflows in the Consolidated Statements of Cash Flows. Effective October 1, 2013, we changed the terms of the ESPP to reduce the discount to 5% from the fair market value of the stock at the end of each fiscal quarter. As a result of this change, the ESPP is no longer considered compensatory, and no compensation expense is recognized for sales of our common stock to employees.
Income Tax, Policy [Policy Text Block]	Income Taxes We account for income taxes using the asset and liability method of accounting. Deferred tax assets and liabilities are recognized based upon anticipated future tax consequences, in each of the jurisdictions that we operate, attributable to: (1) the differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases; and (2) net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The calculation of our tax liabilities involves applying complex tax regulations in different tax jurisdictions to our tax positions. The effect on deferred tax assets and liabilities of a change in tax legislation and/or rates is recognized in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is not more likely than not that such assets will be realized. We do not record tax liabilities on undistributed earnings of international subsidiaries that are permanently reinvested.
Foreign Exchange [Policy Text Block]	Foreign Exchange Our consolidated financial statements are reported in U.S. dollars. Assets and liabilities of international subsidiaries with non-U.S. dollar functional currencies are translated to U.S. dollars at the exchange rates in effect on the balance sheet date, or the last business day of the period, if applicable. Revenues and expenses for each subsidiary are translated to U.S. dollars using a weighted average rate for the relevant reporting period. Translation adjustments resulting from this process are included, net of tax, in OCI. Gains and losses that arise from exchange rate fluctuations for monetary asset and liability balances that are not denominated in an entity’s functional currency are included within other income (expense), net in the Consolidated Statements of Operations. Currency gains and losses of intercompany balances deemed to be long-term in nature or designated as a hedge of the net investment in international subsidiaries are included, net of tax, in OCI. Foreign currency losses, net of hedging, were $3.0 million in 2015 , compared with net foreign currency losses of $5.1 million in 2014 and $3.3 million in 2013 .
Fair Value Measurement [Policy Text Block]	Fair Value Measurements For assets and liabilities measured at fair value, the GAAP fair value hierarchy prioritizes the inputs used in different valuation methodologies, assigning the highest priority to unadjusted quoted prices for identical assets and liabilities in actively traded markets (Level 1) and the lowest priority to unobservable inputs (Level 3). Level 2 inputs consist of quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in non-active markets; and model-derived valuations in which significant inputs are corroborated by observable market data either directly or indirectly through correlation or other means. Inputs may include yield curves, volatility, credit risks, and default rates.
Use of Estimates [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Due to various factors affecting future costs and operations, actual results could differ materially from these estimates.
New Accounting Pronouncements [Text Block]	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date (ASU 2015-14), which deferred the effective date for implementation of ASU 2014-09 by one year and is now effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted but not earlier than the original effective date. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (ASU 2016-08), which clarifies the implementation guidance of principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing (ASU 2016-10), which clarifies the identification of performance obligations and licensing implementation guidance. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients (ASU 2016-12), to improve guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The effective date and transition requirements in ASU 2016-08, ASU 2016-10, and ASU 2016-12 are the same as the effective date and transition requirements of ASU 2015-14. We have not yet selected a transition method and we are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interes t (ASU 2015-03). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the corresponding debt liability. In August 2015, the FASB issued Accounting Standards Update 2015-15, Interest - Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (ASU 2015-15). ASU 2015-15 provides additional guidance on the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. ASU 2015-03 and ASU 2015-15 are effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted, and is to be applied on a retrospective basis. Effective January 1, 2016, we adopted the provisions of ASU 2015-03 and ASU 2015-15. The adoption of the provisions of ASU 2015-03 and ASU 2015-15 will not materially impact our consolidated financial statements and related disclosures. In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Fees Paid in a Cloud Computing Arrangement (ASU 2015-05), which provides guidance about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 is effective for us on January 1, 2016. We adopted this standard on January 1, 2016, and we do not anticipate a material impact from adoption. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330) - Simplifying the Measurement of Inventory (ASU 2015-11). The amendments in ASU 2015-11 apply to inventory measured using first-in, first-out (FIFO) or average cost and will require entities to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the normal course of business, minus the cost of completion, disposal and transportation. Replacement cost and net realizable value less a normal profit margin will no longer be considered. ASU 2015-11 is effective for us on January 1, 2017. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments. The amendments in this update require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period with a corresponding adjustment to goodwill in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts will be recorded in the same period’s financial statements, calculated as if the accounting had been completed at the acquisition date. This ASU is effective for fiscal years beginning after December 15, 2015, and early adoption is permitted. The amendments in this update should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this update with earlier application permitted for financial statements that have not been issued. We adopted this ASU on October 1, 2015, and the adoption of this guidance did not have a material impact on our consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740) (ASU 2015-17). ASU 2015-17 requires deferred tax liabilities and assets to be classified as noncurrent in the Consolidated Balance Sheet. The standard will be effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for financial statements that have not been previously issued. The ASU may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We adopted this ASU on a prospective basis in the fourth quarter of 2015. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires substantially all leases be recognized by lessees on their balance sheet as a right-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. The new standard also will result 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 requires modified retrospective adoption and will be effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently assessing the basis of adoption and evaluating the impact of the adoption of the update on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-07, Investments - Equity Method and Joint Ventures (Topic 323) (ASU 2016-07), which simplified the accounting for equity method investments by eliminating the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. ASU 2016-07 is effective for us on January 1, 2017. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718) , which simplifies several areas within Topic 718. These include the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The standard will be effective for annual reporting periods beginning after December 15, 2016, with early adoption permitted. We are currently assessing the basis of adoption and evaluating the impact of the adoption of the update on our consolidated financial statements.

Specifically, it is the amount by which the market value of Itron’s stock exceeded the exercise price of the outstanding in-the-money options before applicable income taxes, based on our closing stock price on the last business day of the period. The aggregate intrinsic value of stock options exercised during the period is calculated based on our stock price at the date of exercise.

At December 31, 2015, we have net operating loss carryforwards in Luxembourg of $464.5 million that can be carried forward indefinitely, offset by a full valuation allowance. The remaining portion of the loss carryforwards are composed primarily of losses in various other foreign jurisdictions. The majority of these losses can be carried forward indefinitely. At December 31, 2015, there was a valuation allowance of $235.3 million primarily associated with foreign loss carryforwards and foreign tax credit carryforwards (discussed below). (2) For tax return purposes at December 31, 2015, we had: (1) U.S. general business credits of $21.9 million , which begin to expire in 2022; (2) U.S. alternative minimum tax credits of $2.5 million that can be carried forward indefinitely; and (3) U.S. foreign tax credits of $48.0 million, which begin to expire in 2024.

Unrecognized Tax Benefits Related To Uncertain Tax Positions [Table Text Block]	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): Unrecognized tax benefits at January 1, 2013 $ 26,433 Gross increase to positions in prior years 2,154 Gross decrease to positions in prior years (536 ) Gross increases to current period tax positions 1,670 Audit settlements — Decrease related to lapsing of statute of limitations (817 ) Effect of change in exchange rates (289 ) Unrecognized tax benefits at December 31, 2013 $ 28,615 Gross increase to positions in prior years 2,749 Gross decrease to positions in prior years (1,641 ) Gross increases to current period tax positions 3,008 Audit settlements — Decrease related to lapsing of statute of limitations (1,715 ) Effect of change in exchange rates (2,870 ) Unrecognized tax benefits at December 31, 2014 $ 28,146 Gross increase to positions in prior years 6,461 Gross decrease to positions in prior years (2,512 ) Gross increases to current period tax positions 25,741 Audit settlements — Decrease related to lapsing of statute of limitations (908 ) Effect of change in exchange rates (2,048 ) Unrecognized tax benefits at December 31, 2015 $ 54,880 At December 31, 2015 2014 2013 (in thousands) The amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate $ 53,602 $ 26,980 $ 27,694 If certain unrecognized tax benefits are recognized they would create additional deferred tax assets. These assets would require a full valuation in certain locations based upon present circumstances. We classify interest expense and penalties related to unrecognized tax benefits and interest income on tax overpayments as components of income tax expense. The net interest and penalties expense (benefit) recognized is as follows: Year Ended December 31, 2015 2014 2013 (in thousands) Net interest and penalties expense (benefit) $ 880 $ 469 $ (1,443 ) At December 31, 2015 2014 (in thousands) Accrued interest $ 2,105 $ 1,755 Accrued penalties 2,577 2,671 At December 31, 2015, we are under examination by certain tax authorities for the 2000 to 2013 tax years. The material jurisdictions where we are subject to examination for the 2000 to 2013 tax years include, among others, the U.S., France, Germany, Italy, Brazil and the United Kingdom. No material changes have occurred to previously disclosed assessments. In April 2016, the United States Internal Revenue Service (IRS) proposed certain significant adjustments to our research and development tax credit position as part of the 2011 to 2013 tax audit. Management disagrees with the proposed adjustments on technical and factual grounds. We plan to avail ourself of all administrative, and if necessary, judicial remedies and does not expect the adjustments to ultimately result in a material change to our financial position. 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 recorded 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. We file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. We are subject to income tax examination by tax authorities in our major tax jurisdictions as follows: Tax Jurisdiction Years Subject to Audit U.S. federal Subsequent to 1999 France Subsequent to 2009 Germany Subsequent to 2010 Brazil Subsequent to 2009 United Kingdom Subsequent to 2012 Italy Subsequent to 2007
