Basis of Presentation [Abstract] | |
Basis of Presentation | 1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Silver Spring Networks, Inc. (the “Company”, “we”, “us” and “our”) have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information as well as the instructions to Form 10-Q and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three and six months ended June 30, 2015 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2015, or any future period. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Risk Factors,” “Quantitative and Qualitative Disclosures About Market Risk,” and the Consolidated Financial Statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014. The preparation of unaudited condensed consolidated financial statements necessarily requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the condensed consolidated balance sheet dates and the reported amounts of revenues and expenses for the periods presented. Actual results could differ materially from those estimates under different assumptions or conditions. As a result, the quarterly results may not be indicative of the full year results. The condensed consolidated financial statements include the accounts of Silver Spring Networks, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. During the three months ended March 31, 2015, the Company recorded an out-of-period correcting adjustment to deferred cost of revenue that was included in total assets in previous period in the condensed consolidated balance sheets. These correction s resulted in a decrease to the Company's net income of $3.2 million for the three months ended March 31, 2015. The Company recorded these corrections in product cost of revenue in the three months ended March 31, 2015. Management assessed the impact of these errors and concluded that the amounts were not material, either individually or in the agg regate, to any prior period, to the three month period ended March 31, 2015, or to the expected full year financial statements. |

Significant Accounting Policies and Estimates [Abstract] | |
Significant Accounting Policies and Estimates | 2. Significant Accounting Policies and Estimates There have been no material changes to our significant accounting policies described in Note 1, Description of Business, Basis of Presentation and Significant Accounting Policies , in Notes to Consolidated Financial Statements in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2014 that have had a material impact on our condensed consolidated financial statements and related notes, except as described below. Revenue Recognition Through December 31, 2014, due to limited historical experience, for arrangements that contain customer-specific acceptance criteria, revenue has historically been recognized only after obtaining written acceptance for each service area. We perform ongoing evaluation of the sufficiency of historical experience in determining the effect of customer-specific acceptance terms on timing of revenue recognition. During the quarter ended March 31, 2015, following the completion of analyses of historical experience, we determined that we have sufficient objective evidence to conclude that (i) network solution testing conducted in prior deployments can be relied upon to demonstrate that products and services delivered for deployments of other customers will meet acceptance testing criteria, provided that such prior deployments have similar characteristics and substantially similar testing criteria, or (ii) in absence of such evidence from prior deployments, network solution testing in the initial service area for a specific customer deployment can be relied upon to demonstrate that products and services delivered for subsequent service areas within that same deployment will meet subsequent acceptance testing criteria, provided that such initial network solution testing is successfully completed, and the testing criteria in the initial service area are substantially similar to the agreed-upon testing criteria for the remaining service areas. As a result of the above change in assessment of the impact of customer-specific acceptance criteria, revenue and cost of revenue recognized during the three month s ended June 30, 2015 in the condensed statements of o perations included revenue of $ 17.6 millio n and cost of revenue of $ 13.6 million, which otherwise would have been deferred before the change in such assessment. This resulted in a $ 4.0 million decrease in net loss and a $ 0.08 decrease to basic net loss per share during the three months ended Jun e 30, 2015. During the six months ended June 30, 2015, revenue and cost of revenue recognized in the condensed statements of operations as a result of the above change in assessment included revenue of $129. 9 million and cost of revenue of $57.2 million, which otherwise would have been deferred before the change in such assessment. This resulted in a $7 2.7 million increase in net income, $1.47 increase to basic net income per share, and a $1.4 2 increase to diluted net income per share during the six months ended June 30, 2015. Receipt of acceptance from the customers is no longer considered necessary as (i) substantially similar acceptance testing criteria have been met in similar deployments of other customers, or (ii) substantially similar acceptance testing criteria have been met in the initial service area within the customer’s deployment, and all other revenue recognition criteria were met. Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-05 (Subtopic 350-40), Customer's Accounting for Fees Paid in a Cloud Computing Arrangemen t, which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then 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 fiscal years, beginning after December 15, 2015. Early adoption is permitted. We are currently evaluating the impact of the adoption on our consolidated financial statements, if any. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition . Under this new guidance, revenue is recognized 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. The new guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the full retrospective or cumulative effect transition method. In July 2015, the FASB decided to delay the effective date of ASU 2014-09 by one year. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. Earlier adoption is not permitted. As such, t he updated standard will be effective for us in the first quarter of 2018 , with the option to adopt it in the first quarter of 2017 . 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. |

We periodically review our marketable debt securities for other-than-temporary impairment. We consider factors such as the duration, severity and the reason for the decline in value, the potential recovery period and our intent to sell. We also consider whether it is more likely than not that we will be required to (i) sell the debt securities before recovery of their amortized cost basis, and (ii) the amortized cost basis cannot be recovered as a result of credit losses. As of June 30, 2015 , we anticipate that we will recover the entire amortized cost basis of such available-for-sale debt securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the three and six months ended June 30, 2015 and 2014. There were no material gross realized gains or losses from available-for-sale securities during the three and six months ended June 30, 2015 and 2014. |
Fair Value Measurements

Fair Value Measurements [Abstract] | |
Fair Value Measurements | 5 . Fair Value Measurements We determine the fair values of our financial instruments based on a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. Under ASC Topic 820, Fair Value Measurement and Disclosures , the fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value. The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. The guidance for fair value measurements requires that assets and liabilities carried at fair value be classified and disclosed in one of the following categories: Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3—Unobservable inputs in which there is little or no market data, which requires us to develop our own assumptions. Level 1 measurements are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 measurements are obtained from readily available pricing sources for comparable instruments, identical instruments in less active markets, or models using market observable inputs. We did not have any transfers of financial instruments between va luation levels during the six months ended June 30, 2015 and the year ended December 31, 2014 . Assets Measured at Fair Value on a Recurring Basis As of June 30, 2015 , financial assets recorded at fair value on a recurring basis were determined using the following inputs (in thousands): Fair Value Measurement Using Quoted Prices in Active Markets Significant Other Significant for Identical Observable Unobservable Instruments Inputs Inputs (Level 1) (Level 2) (Level 3) Total Cash equivalents: Money-market funds $ $ — $ — $ Total cash equivalents — — Short-term investments: U.S. government and agency obligations — — U.S. and foreign corporate debt securities — — Foreign governments and multi-national agency obligations — — Total short-term investments — — Total assets measured at fair value $ $ $ — $ As of December 31, 2014 , financial assets recorded at fair value on a recurring basis were determined using the following inputs (in thousands): Fair Value Measurement Using Quoted Prices in Active Markets Significant Other Significant for Identical Observable Unobservable Instruments Inputs Inputs (Level 1) (Level 2) (Level 3) Total Cash equivalents: Money-market funds $ $ — $ — $ Total cash equivalents — — Short-term investments: U.S. government and agency obligations — — U.S. and foreign corporate debt securities — — Foreign governments and multi-national agency obligations — — Total short-term investments — — Total assets measured at fair value $ $ $ — $ As of June 30, 2015 and December 31, 2014, there were no liabilities that were measured and recorded at fair value on a recurring basis.

Assets and Liabilities Not Measured at Fair Value The carrying amounts of our accounts receivab le, accounts payable, and accrued and other liabilities approximate fair value due to their short maturities. |

Business Acquisition [Abstract] | |
Business Acquisition | 6. Business Acquisition Acquisition of Detectent On January 16, 2015, we completed the acquisition of Detectent, Inc. (“Detectent”), a privately held corporation that provides customer intelligence solutions for utilities leveraging its data analytics platform, based in Escondido, California. Detectent’s SaaS, subscription, and software solutions help improve advanced metering infrastructure and utility grid operations, ensure revenue protection, and deliver enhanced customer engagement programs. In accordance with the Agreement and Plan of Merger dated as of January 6, 2015, by and among Silver Spring, Detectent and a wholly-owned subsidiary of Silver Spring, Detectent became our wholly-owned subsidiary. The total consideration was $11.6 million, including $7.6 million of cash paid on the acquisition date and $4.0 million of deferred cash consideration (“contingent payments”) to be paid over a two -year period subject to key employees’ retention (“retention period”). Contingent payments associated with future employment conditions will be recorded as compensation expense over the retention period. During the three and six months ended June 30, 2015 , we recorded $0.5 million and $0.9 million, respectively, in compensation expense in the consolidated statement of operations with a corresponding liability included in the accrued liability in the consolidated balance sheets. In accordance with ASC Topic 805, Business Combinations (“ASC 805”), the acquisition of Detectent was accounted for under the acquisition method of accounting. Under the acquisition method of accounting, the total purchase consideration, assets acquired and the liabilities assumed are measured at fair value as of the date of acquisition when control is obtained. The fair value of the consideration transferred and the assets acquired and liabilities assumed was determined by us and in doing so relied in part upon a third-party valuation report to measure the identifiable intangible assets acquired and obligations related to deferred revenue. The following table summarizes the fair value of total consideration transferred for the Detectent acquisition, the total fair value of net identifiable assets acquired and the resulting goodwill recorded (in thousands): [ Cash consideration $ Less: Fair value of net identifiable assets acquired Goodwill $ Goodwill represents the excess of the purchase consideration over the fair value of the underlying net assets acquired and liabilities assumed. The goodwill arising from the Detectent acquisition is largely attributable to the synergies expected to be realized. None of the goodwill recorded as part of the Detectent acquisition will be deductible for income tax purposes. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the acquisition date. The estimated fair value of the identifiable assets acquired and liabilities assumed in the acquisition is based on management’s best estimates. As we finalize certain valuation assumptions, the provisional measurements of certain assets and liabilities, which include accruals, deferred income taxes, and goodwill, are subject to change, and the final purchase price accounting could be different from the amounts presented herein. Assets acquired and liabilities assumed as of January 16, 2015 (in thousands): Cash $ Net other tangible liabilities Intangible assets subject to amortization: Developed technology Customer relationships Non-compete agreements Order backlog Deferred tax liabilities in connection with acquired intangible assets and other fair value adjustments, net Total fair value of net identifiable assets acquired $ Certain closing balance sheet items in connection with the acquisition of Detectent were finalized during the three months ended June 30, 2015. As a result, the net identifiable assets acquired increased by $0.3 million , with a corresponding adjustment to the deferred tax liabilities by $0.1 million. The net impact of $0.2 million of these items was accounted for as m easurement period adjustments during the three months ended June 30, 2015 with a corresponding adjustment to goodwill. Developed technology relates to Detectent’s technology and knowhow which is currently generating revenue. Customer relationships relate to Detectent’s ability to sell existing, in-process and future versions of its products to its existing customers. Non-compete agreements represented the value of the non-compete and non-solicit agreements signed by key employees. Order backlog represents future revenue to be derived from confirmed orders. Developed technology and order backlog were valued using the relief from royalty method based on discounted cash flow (“DCF”). A discount rate of 18.6% was used to value developed technology and 20.1% to value order backlog. The customer relationships and non-compete agreements were valued using multi-period excess earnings method under the income approach based on DCF and using a discount rate of 20.1% . The discount rate used in the present value calculation was derived from a weighted average cost of capital analysis, adjusted to reflect additional benefits or risks related to each asset’s characteristics. The intangible assets are subject to amortization and we expect to amortize these intangible assets on a straight-line basis over their weighted average expected useful lives of approximately one to seven years. Deferred tax assets and liabilities resulting from the acquisition of Detectent have been netted, where applicable. Following the Detectent acquisition, Detectent has become part of our U.S. tax group. Accordingly, the deferred tax liability of $1.0 million which was recognized in the purchase price accounting has been netted with our existing deferred tax assets. As a result, there was a $1.0 million reversal of the Company’s valuation allowance which was recorded as a tax b enefit during the six months ended June 30, 2015 financial statements in accordance with ASC 805. In connection with the acquisition, we incurred $1.5 million of acquisition-related costs that were expensed during the six months ended June 30, 2015. These costs are included primarily as part of general and administration costs in the consolidated statement of operations. Detectent’s financial results have been included in the condensed consolidated financial statements since the acquisition date. Total Detectent revenue represented approximately 1% of the total consolidated revenue recognized during the three and six months ended June 30, 2015 . Acquisition of Streetlight.Vision On May 23, 2014, we completed the acquisition of Streetlight.Vision (“SLV”), a company incorporated under the laws of France, which provides street light control and management software, and paid approximately $8.8 million in cash. In accordance with ASC 805, the acquisition of SLV was accounted for under the acquisition method of accounting and recorded goodwill of $4.7 million at the time of acquisition. Certain closing balance sheet items in connection with the acquisition of SLV were finalized during the first quarter of 2015. As a result, the net assets acquired decreased by $0.1 million which was accounted for a s measurement period adjustment with a corresponding adjustment to goodwill during the first quarter of 2015 . |

Stock-Based Compensation [Abstract] | |
Stock-Based Compensation | 8. Stock-Based Compensation Equity Incentive Plan Our Board of Directors adopted the 2012 Equity Incentive Plan, or the 2012 Plan, which became effective on March 12, 2013 and serves as the successor to our 2003 Stock Option Plan, or the 2003 Plan. Pursuant to the 2012 Plan, 3,400,000 shares of our common stock were initially reserved for grant, plus (1) any shares that were reserved and available for issuance under the 2003 Plan at the time the 2012 Plan became effective, and (2) any shares that become available upon forfeiture or repurchase by us under the 2003 Plan and a stock option plan assumed in connection with a previous acquisition, will be reserved for issuan ce. In addition, the number of s hares of our common stock available for grant and issuance shall be increased on January 1 of each calendar year during the term of the Plan by the lesser of (i) four percent ( 4% ) of the number of s hares of our common stock issued and outstanding on each December 31 immediately prior to the date of in crease, or (ii) such number of s hares determined by the Board. Under the 2012 Plan, we may grant both incentive and non-statutory stock options, restricted stock and restricted stock units to employees, directors and service providers. We may grant options to purchase shares of common stock to employees, directors and service providers at prices not le ss than the fair market value on the date of grant for both Incentive Stock Options, or ISOs, or Nonqualified Stock Options, or NQSOs. ISOs granted to a person who, at the time of the grant, owns more than 10% of the voting power of all classes of stock must be at no less than 110% of the fair market value and expire five years from the date of grant. All other options generally have a contractual term of 10 years. Options generally vest over four years. Restricted stock units, or RSUs, generally vest between two to four years. As of January 1, 2015, the total shares reserved for issuance under the 2012 Plan were automatically increased by 1,962,491 . Employee Stock Purchase Plan Our Board of Directors adopted the 2012 Employee Stock Purchase Plan, or ESPP, which became effective on March 12, 2013, pursuant to which 400,000 shares of our common stock have been reserved for future issuance. In addition, on each January 1 for the first ten calendar years after the first Offering Date, the aggregate n umber of shares of our common s tock rese rved for issuance under the ESPP shall be increased automatically by the number of shares equal to 1% of the total num ber of outstanding shares of our common s tock on the immediately preceding December 31 subject to restrictions defined in the ESPP. Eligible employees can enroll and elect to contribute up to 15% of their compensation through payroll withholdings in each offering period, subject to certain limitations. Each offering period is six months in duration. The purchase price of the stock is the lower of 85% of the fair market value on (a) the first day of the offering period or (b) the purchase date. As of January 1, 2015, the total shares reserved for issuance under the ESPP were automatically increased by 490,622 . Performance Stock Awards In 2015, we granted to our Chief Executive Officer (“CEO”), Chief Financial Officer (“CFO”) and other executive officers performance restricted stock units , or PSUs to acquire up to a certain maximum number of shares of our common stock to be earned based on the common stock price reaching certain share price targets over a period of three years, subject to such individual’s continued service to the Company as a director, officer, employee or consultant. The PSUs will become eligible to vest when the average closing price during the 45 consecutive trading days reaches the share p rice thresholds specified in such individual’s grant at any time before the 3-year anniversary of the grant date. We determined the value of these RSUs using a Monte-Carlo simulation. The fair value of the PSUs is determined to be $5.7 million which will be recognized over the requisite service period using the accelerated method. As of June 30, 2015 and December 31, 2014, there were 5.0 million and 4.3 million shares, respectively, of common stock reserved for future grants under our 2012 Plan and 2012 Employee Stock Purchase Plan. We recorded stock-based compensation expense as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2015 2014 2015 2014 Cost of revenue $ $ $ $ Research and development Sales and marketing General and administrative Stock-based compensation expense $ $ $ $ Of the total stock-based compensation, we recorded $3.7 million and $0.5 million, respectively as stock-based compensation related to our corporate bonus incentive plan during the three months ended June 30, 2015 and 2014. We recorded $5. 2 million and $3. 3 million, respectively as stock-based compensation related to our corporate bonus incentive plan during the six month ended June 30, 2015 and 2014. As of June 30, 2015 and December 31, 2014, stock-based bonus of $5.2 million and $1.9 million, respectively, were recorded as accrued liabilities in the consolidated balance sheets in connection with our corporate bonus incentive plan. The following table summarizes our stock option activity and related information for the six months ended June 30, 2015 (in thousands, except per share data): Options Outstanding Weighted Weighted Average Average Exercise Remaining Aggregate Number of Price per Contractual Intrinsic Shares Share Term (years) Value Balance at December 31, 2014 $ Options granted Options exercised Options cancelled or expired Balance at June 30, 2015 $ $ As of June 30, 2015: Options vested and expected to vest $ $ Options exercisable $ $ The aggregate intrinsic value disclosed above represents the total intrinsic value (the difference between the fair value of our common stock as of June 30, 2015 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on June 30, 2015 . This amount is subject to change based on changes to the fair value of our common stock. The following table summarizes our restricted stock unit activity and related information for the six months ended June 30, 2015 (in thousands, except per share data): Restricted Stock Units Outstanding Weighted Average Grant Number of Date Fair Value Shares per Share Balance at December 31, 2014 $ Restricted stock units granted Restricted stock units vested Restricted stock units cancelled Balance at June 30, 2015 $ Valuation of Employee Stock-Based Compensation We recognize compensation expense for stock-based awards based on their grant-date fair value on a straight-line basis over the service period for which such awards are expected to be outstanding. The fair value of stock options granted pursuant to our equity incentive plans is determined using the Black-Scholes-Merton option pricing model. The determination of fair value is affected by the estimates of our valuation, as well as assumptions regarding subjective and complex variables such as expected employee exercise and forfeiture behavior and our expected stock-price volatility over the expected term of the award. Generally, assumptions are based on historical information and judgment was required to determine if historical trends may be indicators of future outcomes. The fair value of each option grant is estimated on the date of grant. We currently have no history or expectation of paying cash dividends on our common stock. The risk-free interest rate is based on the U.S. Treasury yield for a term consistent with the expected term of the awards in effect at the time of grant. The expected term represents the weighted-average period the stock options are expected to remain outstanding. The expected term is determined based on historical exercise behavior, post-vesting termination patterns, options outstanding and future expected exercise behavior. Until December 31, 2014, we estimated the volatility of our common stock at the date of grant using a combination of our own historical and implied volatility and based on the historical and implied volatility of the stock prices of a peer group of publicly-traded companies for a period equal to the expected life of our stock options. Effective January 1, 2015, we estimate the volatility of our common stock at the date of grant based on our own historical and implied volatility of the stock prices as we believe that we now have sufficient company specific data and provides a reasonable basis on which to base an estimate of expected volatility and we have no reason to believe that our future volatility will differ materially during the expected or contractual term, as applicable, from the volatility calculated from this past information. As of June 30, 2015 , there was $7.0 million and $27.7 million of total unrecognized compensation cost related to non-vested stock-based compensation arrangements related to options and RSUs, respectively, which are expected to be recognized over a weighted-average period of 2.7 and 2.7 years, respectively. |

Restructuring Charges | 12. Restructuring 2014 Restructuring Plan In September 2014, we initiated a restructuring plan (the “2014 Restructuring Plan”) to refocus our strategy, optimize our structure, and improve operational efficiencies. The 2014 Restructuring Plan included a worldwide workforce reduction. As a result, we recorded $1.8 million in severance costs as restructuring charges during the third quarter of 2014. We recorded $1.1 million and $1.3 million in severance and other related costs as restructuring charges during the three and six months ended June 30, 2015 , respectively, under the 2014 Restructuring Plan. In connection with the 2014 Restructuring Plan, we expect to record aggregate future charges of approximately $0.3 million to $0.8 million.

Commitments and Contingencies | 13. Commitments and contingencies Operating and Capital Leases Our primary operating lease commitment as of June 30, 2015 , related to our headquarters in Redwood City, California, requires monthly lease payments through April 2016. We recognize rent expense on a straight-line basis over the lease period. Rent expense for all facility leases was $1.3 million and $1.2 million for the three months ended June 30, 2015 and 2014, respectively, and $2.5 million and $2.6 million for six months ended June 30, 2015 and 2014, respectively.

In June 2011, EON Corp. IP Holdings, LLC, a non-producing entity, or EON, filed suit in United States District Court for the Eastern District of Texas, Tyler Division against us and a number of smart grid providers. The lawsuit alleges infringement of United States Patent Nos. 5,388,101 (the “’101 Patent”) , 5,481,546 (the “’546 Patent”) , and 5,592,491 (the “’491 Patent,” and together with the ‘101 Patent and the ‘546 Patent, the “EON Patents”) by certain networking technology and services that we and the other defendants provide. Other defendants included Landis+Gyr AG, Aclara Power-Line Systems Inc., Elster Solutions, LLC, Itron, Inc. and Trilliant Networks Inc., all of which settled with EON prior to trial. We filed answers, affirmative defenses and counterclaims denying the plaintiff’s allegations and asserting that the plaintiff’s patents are invalid. A trial was held in June 2014. After the trial, the jury determined that we had infringed certain, but not all, of the claims under the EON Patents, and returned a verdict against us in the amount of $18.8 million. The court ruled there was insufficient evidence to support EON’s allegation of willful infringement and granted our motion to dismiss that claim. In June 2014, we filed post-trial motions with the court seeking, among other things, judgment as a matter of law to set aside the jury verdict, or in the alternative, a new trial. In its post-trial motions, EON sought pre-judgment interest and attorneys’ fees. Following post-trial motions, the court reduced the damage award to approximately $13.0 million, and in December 2014, entered a final judgment in that amount plus approximately $1.5 million in pre-judgment interest. The court subsequently revised the final judgment to include additional costs of about $0.2 million and entered an amended final judgment in December 2014. All of the EON Patents have expired and therefore EON is not seeking, and EON may not recover, any additional sums as royalties for our sales of products going forward. In December 2014, we filed a notice of appeal with the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. In order to stay the execution of the final judgment pending the appeal, in December 2014 we filed a surety bond in the amount of $17.6 million, which includes an additional 20% of the final judgment for post-judgment interest and expenses expected to be incurred during the appeal process, in accordance with court rules. The bond was issued by Zurich Insurance and is collateralized with a standby letter of credit in the amount of $13.0 million, the amount of the damage award, as described below in “ Customer Performance and Other Commitments.” Upon completion of the appeal process, both the surety bond and standby letter of credit will be released. In January 2015, the District Court accepted the bond and entered the stay of execution of the judgment. EON filed a notice of cross appeal in January 2015, which it subsequently dropped in June 2015. We filed our opening appellate brief in March 2015, and EON filed its principal brief in May 2015. We filed our reply brief in July 2015. We expect the appeal process to take place during 2015 and perhaps into early 2016. We continue to believe that the evidence and the law do not support the jury’s findings of infringement, validity, and the award of damages, and intend to continue vigorously defending the action, including exercising all available appeals. However, given the inherent uncertainty in predicting the ultimate outcome of the appeals process, we believe it is reasonably possible that a material loss of up to $14.7 million, the amount of the amended final judgment, may result from these proceedings. In continuing to assess the impact of the jury verdict and the judgment on our financial statements, we will continue to evaluate the jury verdict, the court’s rulings on the post-trial motions and the likelihood of a successful appeal. TransData/OG&E Patent Litigation. In September 2011, TransData, Inc., or TransData, filed suit in United States District Court for the Western District of Oklahoma, against Oklahoma Gas & Electric Company (“OG&E”), alleging infringement of United States Patent Nos. 6,181,294, 6,462,713, and 6,903,699 by certain wireless communication-enabled meters, including General Electric Company (“GE”) meters with our wireless modules. We have agreed with GE to contribute to pay the defense of OG&E in connection with the TransData suit. An early claim construction hearing was held regarding one claim term in February 2013, and a hearing for the full claim construction was held in September 2013, on which the court issued an order in October 2013. In May 2014, GE filed reexamination requests on the TransData patents at issue with the U.S. Patent and Trademark Office (the “USPTO”). In August and September 2014, GE also petitioned the USPTO for inter partes review of each patent. In October 2014, OG&E filed a motion to stay the litigation pending the reexamination of the patents by the USPTO, which the court denied in January 2015. In March 2015, the USPTO issued decisions declining to institute the inter partes review. Additionally, the USPTO has indicated that all claims for which reexamination was requested are allowable without amendment. Pre-trial proceedings in the matter are ongoing, each side has filed pre-trial motions, and briefing on these pre-trial motions is complete. The court has not yet set any hearing date. We believe that OG&E has meritorious defenses to TransData’s allegations, and that OG&E will continue to vigorously defend itself . Linex Patent Litigation. In March 2013, Linex Technologies, Inc., a non-producing entity, or Linex, filed suit against us in United States District Court for the Southern District of Florida. Linex alleged that certain of our networking technology infringes United States Patent Nos. 6,493,377 and 7,167,503. We filed an answer in May 2013. In January 2014, the court granted the plaintiff’s request for a stay of the matter, pending reexamination of the patents at issue by the USPTO. In September 2014, Linex amended certain patent claims and canceled certain other patent claims based upon the USPTO’s completed reexaminations, and in October 2014, the court lifted the stay of the matter. In January 2015, Linex filed an amended complaint to incorporate facts related to the completed reexaminations, and we filed an answer responding to the complaint and raising additional defenses. In June 2015, the court stayed the action pending the USPTO’s completion of further ex parte reexaminations of the patents at issue. We believe that we have meritorious defenses to Linex’s allegations and intend to continue vigorously defending against the action. We have not recorded any amounts for contingent losses associated with the matters described above based on its belief that losses, while reasonably possible, are not probable. Unless otherwise stated, we are currently unable to predict the final outcome of these lawsuits and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. We are directly involved with various unresolved legal actions and claims, and are indirectly involved with proceedings by administrative bodies such as public utility commissions, arising in the ordinary course of business. We do not believe that any liability from any reasonably foreseeable disposition of such legal actions and claims, individually or in the aggregate, would have a material effect on our consolidated financial statements. There are many uncertainties associated with any litigation or claim, and we cannot be certain that these actions or other third-party claims will be resolved without costly litigation, fines and/or substantial settlement payments. If that occurs, our business, financial condition and results of operations could be materially and adversely affected. If information becomes available that causes us to determine that a loss in any of our pending litigation matters, claims or settlements is probable, and a reasonable estimate of the loss associated with such events can be made, we will record the estimated loss at that time. Customer Performance and Other Commitments Certain customer agreements require us to obtain letters of credit or surety bonds in support of our obligations under such arrangements. These letters of credit or surety bonds typically provide a guarantee to the customer for future performance, which usually covers the deployment phase of a contract and may on occasion cover the operations and maintenance phase of service contracts. As of June 30, 2015 and December 31, 2014, we had a total of $21.4 million, including $13.0 million related to EON Patent Litigation mentioned above, and $17.0 million, respectively, of standby letters of credit issued under the credit facility with a financial institution, of which $0.5 million (AUD $0.6 million) and $0.5 million (AUD $0.6 million), respectively, were denominated in Australian dollars. In accordance with the terms of our credit facility, increases or decreases in the exchange rate between the Australian dollar and the U.S. dollar will increase or decrease the amount available to us under the credit facility. As of June 30, 2015 and December 31, 2014 , we had a $20.3 million unsecured surety bond. The surety bond provides a financial guarantee to support performance obligations under certain customer agreements. In the event any such letters of credit or surety bonds are called, we would be obligated to reimburse the issuer of the letter of credit or surety bond. We do not believe there will be any claims against currently outstanding letters of credit or surety bonds. Indemnification Commitments Directors, Officers and Employees. In accordance with our bylaws and/or pursuant to indemnification agreements we have entered into with directors, officers and certain employees, we have indemnification obligations to our directors, officers and employees for claims brought against these persons arising out of certain events or occurrences while they are serving at our request in such a capacity. We maintain a director and officer liability insurance coverage to reduce our exposure to such obligations, and payments made under these agreements. To date, there have been no indemnification claims by these directors, officers and employees. Customers and Third Party Device Manufacturers. Refer to the discussion above under the heading Legal Contingencies for a description of our indemnification obligations. Our contracts with customers and third party device manufacturers typically provide indemnification for claims filed by third parties alleging that our products and services sold to the customer or manufacturer infringe or misappropriate any patent, copyright, trademark or other intellectual property right. In our customer contracts, we also typically provide an indemnification for third-party claims resulting from death, personal injury or property damage caused by the negligence or willful misconduct of our employees and agents in connection with the performance of certain contracts. Under our customer and third party device manufacturer indemnities, we typically agree to defend the utility customer or third party device manufacturer, as the case may be, from such claims, and pay any resulting costs, damages and attorneys’ fees awarded against the indemnified party with respect to such claims, provided that (a) the indemnified party promptly notifies us in writing of the claim, (b) the indemnified party provides reasonable assistance to us at our expense, and (c) we have sole control of the defense and all related settlement negotiations. Insurance. We maintain various insurance coverage policies, subject to policy limits, that enable us to recover a portion of any amounts paid by us in connection with our obligation to indemnify our customers and third party device manufacturers. However, because our maximum liability associated with such indemnification obligations generally is not stated explicitly in the related agreements, and further because many states prohibit limitations of liability for such indemnified claims, the maximum potential amount of future payments we could be required to make under these indemnification provisions could significantly exceed insurance policy limits. Historically, payments made by us under these indemnification provisions have not had a material effect on our results of operations, financial position or cash flows. |

Revenue Recognition | Revenue Recognition Through December 31, 2014, due to limited historical experience, for arrangements that contain customer-specific acceptance criteria, revenue has historically been recognized only after obtaining written acceptance for each service area. We perform ongoing evaluation of the sufficiency of historical experience in determining the effect of customer-specific acceptance terms on timing of revenue recognition. During the quarter ended March 31, 2015, following the completion of analyses of historical experience, we determined that we have sufficient objective evidence to conclude that (i) network solution testing conducted in prior deployments can be relied upon to demonstrate that products and services delivered for deployments of other customers will meet acceptance testing criteria, provided that such prior deployments have similar characteristics and substantially similar testing criteria, or (ii) in absence of such evidence from prior deployments, network solution testing in the initial service area for a specific customer deployment can be relied upon to demonstrate that products and services delivered for subsequent service areas within that same deployment will meet subsequent acceptance testing criteria, provided that such initial network solution testing is successfully completed, and the testing criteria in the initial service area are substantially similar to the agreed-upon testing criteria for the remaining service areas. As a result of the above change in assessment of the impact of customer-specific acceptance criteria, revenue and cost of revenue recognized during the three month s ended June 30, 2015 in the condensed statements of o perations included revenue of $ 17.6 millio n and cost of revenue of $ 13.6 million, which otherwise would have been deferred before the change in such assessment. This resulted in a $ 4.0 million decrease in net loss and a $ 0.08 decrease to basic net loss per share during the three months ended Jun e 30, 2015. During the six months ended June 30, 2015, revenue and cost of revenue recognized in the condensed statements of operations as a result of the above change in assessment included revenue of $129. 9 million and cost of revenue of $57.2 million, which otherwise would have been deferred before the change in such assessment. This resulted in a $7 2.7 million increase in net income, $1.47 increase to basic net income per share, and a $1.4 2 increase to diluted net income per share during the six months ended June 30, 2015. Receipt of acceptance from the customers is no longer considered necessary as (i) substantially similar acceptance testing criteria have been met in similar deployments of other customers, or (ii) substantially similar acceptance testing criteria have been met in the initial service area within the customer’s deployment, and all other revenue recognition criteria were met. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-05 (Subtopic 350-40), Customer's Accounting for Fees Paid in a Cloud Computing Arrangemen t, which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then 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 fiscal years, beginning after December 15, 2015. Early adoption is permitted. We are currently evaluating the impact of the adoption on our consolidated financial statements, if any. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition . Under this new guidance, revenue is recognized 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. The new guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the full retrospective or cumulative effect transition method. In July 2015, the FASB decided to delay the effective date of ASU 2014-09 by one year. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. Earlier adoption is not permitted. As such, t he updated standard will be effective for us in the first quarter of 2018 , with the option to adopt it in the first quarter of 2017 . 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. |
