Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business and Basis of Presentation | 1. Description of Business and Basis of Presentation Description of Business Silver Spring Networks, Inc. (the “Company”, “we”, “us” and “our”) has more than a decade of experience creating, building and successfully deploying large scale networks and solutions enabling the Internet of Things, or IoT, for critical infrastructure. The IoT refers to a system where a diversity of physical devices have the capacity to communicate using internet technologies. Our first area of focus was in energy, creating a leading grid network by applying advanced networking technology and solutions to the power grid. We have broadened our focus beyond the smart grid to other utility networks including gas and water, and other critical infrastructure such as street lights, enabling smarter and more efficient cities. Longer term, we look to expand our reach into an even broader range of IoT markets by working with our customers, partners and developers to open their networks to third parties and support a wider range of devices, applications and solutions. Proposed Transaction with Itron, Inc. On September 17, 2017, we entered in an Agreement and Plan of Merger (the “Merger Agreement”) with Itron, Inc. (“Itron”) and Ivory Merger Sub, Inc., a wholly-owned subsidiary of Itron (“Merger Sub”), pursuant to which Itron has agreed to acquire all of the outstanding shares of our common stock for $16.25 per share in cash, and we would become a wholly-owned subsidiary of Itron (the “Merger”) if the Merger is completed. We expect the Merger to be completed in late 2017 or early 2018, subject to certain conditions, including, among others, receipt of customary regulatory approvals and approval by our stockholders. We incurred transaction-related costs of approximately $3.3 million during the three months ended September 30, 2017 in connection with the Merger and expect to incur additional costs related to the Merger in subsequent quarters. For additional information related to the Merger and the Merger Agreement, please refer to our Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on September 18, 2017 and the Preliminary Proxy Statement on Schedule 14A filed with the SEC on November 2, 2017. The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement included as Exhibit 2.1 to our Current Report on Form 8-K filed September 18, 2017. Upon completion of the Merger, shares of our common stock will cease trading on the New York Stock Exchange. Other than $3.3 million of transaction expenses associated with the proposed Merger, which were primarily recorded to general and administrative expense in the accompanying Condensed Consolidated Statement of Operations, for the three and nine months ended September 30, 2017, the terms of the Merger Agreement did not impact the Company’s Condensed Consolidated Financial Statements. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, for interim financial information as well as the instructions to Form 10-Q and applicable rules and regulations of the 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 nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017, 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, 2016. 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 the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. |

Accounting Policies [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 Consolidated Financial Statements and Supplementary Data Improvements to Employee Share-Based Payment Accounting, Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting • Income tax accounting – The recognition of previously unrecognized excess tax benefits using the modified retrospective method, which requires a cumulative-effect adjustment to accumulated deficit for previously unrecognized excess tax benefits. The only jurisdiction in which we had previously unrecognized excess tax benefits was in the United States. Since we maintain a full valuation allowance against our U.S. deferred tax assets, no adjustment to our accumulated deficit to reflect the recognition of excess tax benefits from prior years was required upon adoption of this new standard. The effects of recognizing these historical excess tax benefits increased our gross deferred tax assets by $9.1 million for federal and by $0.5 million for state, which were fully offset by the full valuation allowance against our U.S. deferred tax assets. As such, the adoption did not result in any change to our net U.S. deferred tax asset position. Tax benefits previously recorded in additional paid-in capital prior to the adoption of the guidance will remain in additional paid-in . • Cash flow presentation of excess tax benefits – This standard also requires excess tax benefits to be classified as an operating activity, consistent with other income tax cash flows, and may be applied either on a prospective transition or a retrospective transition method. We applied this standard using the prospective transition method, which had no impact to our condensed consolidated statement of cash flows for the nine months ended September 30, 2017. • Forfeitures – This standard enabled us to make an election to change from estimating forfeitures to accounting for forfeitures when they occur. We adopted this change on a modified retrospective basis which resulted in us recording a cumulative effect change that increased our accumulated deficit by $0.2 million and increased our additional paid-in capital by the same amount. Recently Issued Accounting Pronouncements In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), Revenue Recognition We anticipate the new standard will have a material impact on our consolidated financial statements. While we are continuing to assess all potential impacts of the standard, we currently believe the most significant impact relates to our accounting for contingency provisions, certain software and software-related elements, and costs to obtain or fulfill a contract as explained below: • Contingency provisions. Contingency provisions currently limit the amount of the total arrangement consideration under multiple deliverable contracts that can be allocated to delivered and accepted products and services. Under the new standard, these provisions are considered variable consideration for which a probability estimate can be made. As a result, we will include in arrangement consideration the amounts expected rather than record deferred revenue for the full amount of the contingency until such provisions have lapsed. • Software and software-related elements under ASC 985-605. Under current GAAP, because we have not yet established Vendor-Specific Objective Evidence or VSOE for PCS or professional services, revenue for software and software-related elements under ASC 985-605 is recognized ratably over the longest service period. The requirement to have VSOE for undelivered elements to enable the separation of revenue for the delivered software is eliminated under the new standard. Accordingly, under the new standard we will be able to recognize as revenue a portion of the arrangement fee upon delivery of the software. • Costs to obtain or fulfill a contract. We currently record sales commissions and costs of providing services in the period incurred. Under ASC 606, such incremental costs are required to be capitalized, then amortized on a basis that is consistent with the recognition of the products and services transferred to the customer. Therefore, we will be required to recognize an asset for such costs with the expense potentially recorded in a future period to match the transfer of products and services. Due to the complexity of our contracts, the actual revenue recognition treatment required under the new standard for our arrangements may be dependent on contract-specific terms and may vary in some instances. |

Net Loss Per Share | 3. Net loss per share Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted-average number of shares of common stock and potentially dilutive securities outstanding during the period. consist of common shares issuable upon issuances of shares pursuant to the 2012 Employee Stock Purchase Plan, or ESPP, vesting of and contingently issuable We include the common shares underlying PSUs in the calculation of diluted per share when they become contingently issuable and exclude such shares when they are not contingently issuable.

As of December 31, 2016, approximately 83% and 9% of our cash, cash equivalents and short-term investments were held with two financial institutions, respectively. As of September 30, 2017, $0.8 million of restricted cash was designated as a collateral for a bank guarantee issued by HSBC Bank USA, National Association, or HSBC, to support our performance obligation under an agreement with one customer. The guarantee will expire in July 2023 unless cancelled on an earlier date; accordingly, we recorded this amount in other long-term assets in our condensed consolidated balance sheets. Contractual Maturities The contractual maturities of cash equivalents and short-term investments were as follows (in thousands): As of September 30, 2017 As of December 31, 2016 Amortized Aggregate Amortized Aggregate Cost Basis Fair Value Cost Basis Fair Value Due within one year $ 44,459 $ 44,393 $ 19,017 $ 18,988 Due from 1 year through 3 years 25,166 24,991 51,219 50,923 Total cash equivalents and short-term investments $ 69,625 $ 69,384 $ 70,236 $ 69,911 The following table presents gross unrealized losses and fair values for investments in an unrealized loss position as of September 30, 2017 and December 31, 2016, aggregated by investment category (in thousands): As of September 30, 2017 As of December 31, 2016 Less than 12 Months Greater than 12 Months Total Total (Less Than 12 Months) Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss U.S. and foreign corporate debt securities $ 14,459 $ (17 ) $ 11,963 $ (37 ) $ 26,422 $ (54 ) $ 27,520 $ (116 ) U.S. government and agency obligations 15,530 (29 ) 25,397 (158 ) 40,927 (187 ) 40,356 (209 ) Total $ 29,989 $ (46 ) $ 37,360 $ (195 ) $ 67,349 $ (241 ) $ 67,876 $ (325 ) 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 September 30, 2017 and 2016, we anticipated that we would recover the entire amortized cost basis of such available-for-sale debt securities and determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the three and nine months ended September 30, 2017 and 2016. It is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases. There were insignificant gross realized gains or losses from available-for-sale securities during the three and nine months ended September 30, 2017 and 2016. |

Fair Value Disclosures [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 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 valuation levels during the nine months ended September 30, 2017 and the year ended December 31, 2016. Assets Measured at Fair Value on a Recurring Basis As of September 30, 2017, financial assets recorded at fair value on a recurring basis are summarized below (in thousands): Fair Value Measurement Using Quoted Prices in Significant Active Markets for Other Identical Observable Instruments Inputs (Level 1) (Level 2) Total Cash equivalents: Money market mutual funds $ 2,035 $ — $ 2,035 Total cash equivalents 2,035 — 2,035 Short-term investments: U.S. Government and agency obligations — 40,927 40,927 U.S. and foreign corporate debt securities — 26,422 26,422 Total short-term investments — 67,349 67,349 Total assets measured at fair value $ 2,035 $ 67,349 $ 69,384 As of December 31, 2016, financial assets recorded at fair value on a recurring basis are summarized below (in thousands): Fair Value Measurement Using Quoted Prices in Significant Active Markets for Other Identical Observable Instruments Inputs (Level 1) (Level 2) Total Cash equivalents: Money market mutual funds $ 2,035 $ — $ 2,035 Total cash equivalents 2,035 — 2,035 Short-term investments: U.S. government and agency obligations — 40,356 40,356 U.S. and foreign corporate debt securities — 27,520 27,520 Total short-term investments — 67,876 67,876 Total assets measured at fair value $ 2,035 $ 67,876 $ 69,911 As of September 30, 2017 and December 31, 2016, there were no liabilities that are measured and recorded at fair value on a recurring basis. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis As of September 30, 2017 Our intangible assets are measured at fair value on a nonrecurring basis, if impairment is indicated. During the three and nine months ended September 30, 2016, intangible assets were measured at fair value that resulted in the recording of an impairment charge of $2.2 million. We measured the fair value of these assets primarily using discounted cash flow projections. The discounted cash flow projections require estimates of expected revenue, gross margin and operating expenses associated with these assets. Intangible assets are classified as Level 3 assets due to the absence of quoted market prices. See Note 7, Goodwill and Intangibles Assets for further information. Assets and Liabilities Not Measured at Fair Value The carrying amounts of our accounts receivable, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. |

Business Acquisition | 6. Business Acquisition On January 16, 2015, we completed the acquisition of Detectent, Inc., or Detectent, a privately held corporation that provides customer intelligence solutions for utilities leveraging its data analytics platform, and paid $7.6 million in cash consideration. The acquisition of Detectent was accounted for under the acquisition method of accounting. We paid and held $4.0 million of deferred cash consideration, or contingent payments, in an escrow account, to be released over a two-year period subject to the retention of key employees of Detectent, or retention period. Contingent payments associated with future employment conditions were recorded as compensation expense over the retention period. We released $1.0 million from the escrow account in 2016, and released the remaining $3.0 million from the escrow account in February 2017, upon satisfaction of the retention terms of the acquisition agreement. |

Stock-Based Compensation | 8. Stock-Based Compensation Equity Incentive Plan and Employee Stock Purchase Plan As of September 30, 2017 and December 31, 2016, there were 7.0 million and 5.9 million shares, respectively, of common stock reserved for future grants under our ESPP and 2012 Equity Incentive Plan. Performance Stock Units In May 2017, we granted to our Chief Executive Officer, or CEO, Chief Financial Officer, or CFO, and other executive officers PSUs to receive up to an aggregate number of 0.2 million shares of our common stock, subject to the achievement of certain performance targets set by the Compensation Committee and such individual’s continued service to us as a director, officer, employee or consultant. The PSUs will become earned and eligible to vest when the performance condition is met. The earned PSUs, if any, will vest in equal annual installments over three years from the date of grant. The aggregate grant-date fair value of these PSUs is approximately $2.3 million based on the closing price of our common stock on the grant date, which will be recognized over the requisite service period using the accelerated attribution method.

Commitments and Contingencies | 12. Commitments and contingencies Operating and Capital Leases Our primary operating lease commitment as of September 30, 2017, related to our headquarters in San Jose, California, requires monthly lease payments through September 2026. We recognize rent expense on a straight-line basis over the lease period. Where leases contain escalation clauses, rent abatements, or concessions, such as rent holidays and landlord or tenant incentives or allowances, we apply them in the determination of straight-line rent expense over the lease term. Rent expense for all facility leases was $2.0 million and $1.8 million for the three months ended September 30, 2017 and 2016, respectively, and $6.0 million and $6.1 million for the nine months ended September 30, 2017 and 2016, respectively.

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 United States Patent and Trademark Office, or 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. In July 2017, the USPTO issued a reexamination certificate with all of the claims cancelled for the ‘377 patent. We believe that we have meritorious defenses to Linex’s allegations and intend to continue vigorously defending against the action. Acoustic Technology Patent Litigation. In July 2016, Acoustic Technology, Inc. or ATI, a non-producing entity, filed suit in United States District Court for the Eastern District of Texas, Marshall Division against us. The lawsuit alleges infringement of United States Patent Nos. 5,986,574, and 6,509,841 by certain meters and networking technology and services that we provide. The patents will expire in late 2017 and early 2018. We filed a motion to dismiss, as well as a motion to transfer the matter to the Northern District of California, in September 2016. The motion to transfer was granted in March 2017. Also in March 2017, we filed several petitions for inter partes review with the USPTO, requesting the USPTO to find certain claims of the ATI Patents to be unpatentable. In July 2017, the court stayed the suit pending review of the petitions for inter partes review by the USPTO. In September 2017, the USPTO instituted trial on all three of the inter partes review petitions we filed, on all requested grounds. In October 2017, the court ordered that the stay of the litigation be maintained. The court also ordered the parties to participate in mediation, to be concluded by April 2018. We believe that we have meritorious defenses to ATI’s allegations and intend to vigorously defend ourselves. Weatherproof Wireless Patent Litigation. In October 2017, Weatherproof Wireless, LLC, a non-producing entity, filed suit in Federal District Court in Delaware against us. The lawsuit alleges infringement of United States Patent No. 7,522,876 by certain networking technology that we provide. We are in the process of analyzing the complaint, but believe that we have meritorious defenses to Weatherproof’s allegations and intend to vigorously defend ourselves . In addition to the matters described above, from time to time we may be subject to other legal proceedings and claims in the ordinary course of business. We have received, and may in the future continue to receive, claims from third parties asserting infringement of their intellectual property rights. We may, from time to time, also be subject to various legal or government claims, disputes, or investigations. Such matters may include, but not be limited to, claims, disputes, or investigations related to warranty, refund, breach of contract, employment, intellectual property, government regulation, compliance or other matters. Future litigation may be necessary to defend ourselves and our customers by determining the scope, enforceability and validity of third-party rights or to establish our rights. There can be no assurance with respect to the outcome of any current or future litigation brought against us or pursuant to which we have indemnification obligations and the outcome could have a material adverse impact on our business, operating results and financial condition. As of September 30, 2017, we have not recorded any amounts for contingent losses associated with the matters described above based on our 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 September 30, 2017 and December 31, 2016, we had a total of $15.8 million and $17.2 million, respectively, of standby letters of credit issued under a credit facility with a financial institution. As of September 30, 2017 and December 31, 2016, $0.5 million (AUD $0.6 million) and $4.6 million (AUD $6.1 million) of these standby letters of credit were denominated in Australian dollars, respectively, and $3.3 million (AED 12.4 million) and $4.5 million (AED 16.4 million) of these standby letters of credit were denominated in United Arab Emirates Dirham, respectively. In accordance with the terms of our credit facility, fluctuations in the exchange rate will increase or decrease the amount available to us under the credit facility. On December 18, 2015, we entered into a senior secured credit facilities credit agreement, or Credit Facility, with Silicon Valley Bank and HSBC, with an original maturity of December 18, 2017. The Credit Facility provides a revolving loan facility in an aggregate amount not to exceed $75.0 million, with an available letter of credit sub-facility in the aggregate amount of $75.0 million and an available swingline sub-facility in the aggregate amount of $5.0 million. As of September 30, 2017, there were no borrowings outstanding under the Credit Facility; however, this line of credit is backing $15.8 million of letters of credit, leaving $59.2 million of available capacity for cash borrowings or additional letters of credit or swingline loan, subject to compliance with financial covenants and other customary conditions to borrowings, which varies at each period end. As of September 30, 2017, we were in compliance with the financial covenants in the credit agreement. In November 2017, we extended the maturity of the Credit Facility to June 18, 2018. As of September 30, 2017, we had a total of $16.8 million in unsecured surety bonds. The surety bonds provide 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 letters of credit or surety bonds. 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 coverages, 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. |

Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting • Income tax accounting – The recognition of previously unrecognized excess tax benefits using the modified retrospective method, which requires a cumulative-effect adjustment to accumulated deficit for previously unrecognized excess tax benefits. The only jurisdiction in which we had previously unrecognized excess tax benefits was in the United States. Since we maintain a full valuation allowance against our U.S. deferred tax assets, no adjustment to our accumulated deficit to reflect the recognition of excess tax benefits from prior years was required upon adoption of this new standard. The effects of recognizing these historical excess tax benefits increased our gross deferred tax assets by $9.1 million for federal and by $0.5 million for state, which were fully offset by the full valuation allowance against our U.S. deferred tax assets. As such, the adoption did not result in any change to our net U.S. deferred tax asset position. Tax benefits previously recorded in additional paid-in capital prior to the adoption of the guidance will remain in additional paid-in . • Cash flow presentation of excess tax benefits – This standard also requires excess tax benefits to be classified as an operating activity, consistent with other income tax cash flows, and may be applied either on a prospective transition or a retrospective transition method. We applied this standard using the prospective transition method, which had no impact to our condensed consolidated statement of cash flows for the nine months ended September 30, 2017. • Forfeitures – This standard enabled us to make an election to change from estimating forfeitures to accounting for forfeitures when they occur. We adopted this change on a modified retrospective basis which resulted in us recording a cumulative effect change that increased our accumulated deficit by $0.2 million and increased our additional paid-in capital by the same amount. Recently Issued Accounting Pronouncements In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), Revenue Recognition We anticipate the new standard will have a material impact on our consolidated financial statements. While we are continuing to assess all potential impacts of the standard, we currently believe the most significant impact relates to our accounting for contingency provisions, certain software and software-related elements, and costs to obtain or fulfill a contract as explained below: • Contingency provisions. Contingency provisions currently limit the amount of the total arrangement consideration under multiple deliverable contracts that can be allocated to delivered and accepted products and services. Under the new standard, these provisions are considered variable consideration for which a probability estimate can be made. As a result, we will include in arrangement consideration the amounts expected rather than record deferred revenue for the full amount of the contingency until such provisions have lapsed. • Software and software-related elements under ASC 985-605. Under current GAAP, because we have not yet established Vendor-Specific Objective Evidence or VSOE for PCS or professional services, revenue for software and software-related elements under ASC 985-605 is recognized ratably over the longest service period. The requirement to have VSOE for undelivered elements to enable the separation of revenue for the delivered software is eliminated under the new standard. Accordingly, under the new standard we will be able to recognize as revenue a portion of the arrangement fee upon delivery of the software. • Costs to obtain or fulfill a contract. We currently record sales commissions and costs of providing services in the period incurred. Under ASC 606, such incremental costs are required to be capitalized, then amortized on a basis that is consistent with the recognition of the products and services transferred to the customer. Therefore, we will be required to recognize an asset for such costs with the expense potentially recorded in a future period to match the transfer of products and services. Due to the complexity of our contracts, the actual revenue recognition treatment required under the new standard for our arrangements may be dependent on contract-specific terms and may vary in some instances. |
