Accounting Policies [Abstract]
Significant Accounting Policies	In October 2016, the FASB issued Accounting standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (''ASU 2016-16''). ASU 2016-16 modifies how intra-entity transfer of assets other than inventory are accounted for and presented in the financial statements. ASU 2016-16 is effective for public companies for annual reporting periods beginning after December 15, 2017. The Company adopted this ASU in the first quarter of 2017. The Company recognized a tax charge of $2.0 million related to intra-entity transactions other than inventory which could not be previously recognized. The unrecognized tax charge is reflected as an adjustment to retained earnings. In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting (''ASU 2016-09''). ASU 2016-09 simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016. The Company adopted this ASU in the first quarter of 2017. Upon adoption, the Company no longer uses a forfeiture rate in the calculation of stock based compensation expense. The impact of this election did not result in a significant charge to retained earnings from applying an estimated forfeiture rate in previous periods. The balance of the unrecognized excess tax benefits was reversed with the impact recorded to retained earnings and included changes to the valuation allowance as a result of the adoption. The Company has excess tax benefits for which a benefit could not be previously recognized of $4.5 million. Due to the full valuation allowance on the U.S. deferred tax assets, there was no impact to the financial statements beyond disclosure as a result of this adoption. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet and aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the requirements of ASU 2016-02 and has not yet determined its impact on the condensed consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is the new comprehensive revenue recognition standard that will supersede all existing revenue recognition guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to a customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which was issued in August 2015, revised the effective date for this ASU to annual and interim periods beginning on or after December 15, 2017, with early adoption permitted, but not earlier than the original effective date of annual and interim periods beginning on or after December 15, 2016, for public entities. The new standard permits adoption either by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providing certain additional disclosures. The Company does not plan to early adopt this new standard, and accordingly, the Company will adopt the new standard effective January 1, 2018. The Company plans to adopt using the modified retrospective approach. The Company's evaluation of the impact of the new standard on the Company's accounting policies, processes, and system requirements is ongoing. While the Company continues to assess all potential impacts under the new standard, the Company does not believe there will be significant changes to the timing of recognition of hardware sales, software license sales or service contracts. As part of the Company's preliminary evaluation, the Company also considered the impact of the guidance in ASC 340-40, "Other Assets and Deferred Costs; Contracts with Customers". This guidance requires the capitalization of all incremental costs that we incur to obtain a contract with a customer that the Company would not have incurred if the contract had not been obtained, provided the Company expects to recover the costs. The Company preliminarily believes that there will not be significant changes to the timing of the recognition of sales commissions since the Company's commission plan is earned based on the recognition of revenue; however, there is a potential that the amortization period for commission costs may be longer than the contract term in some cases, as the new cost guidance requires entities to determine whether the costs relate to specific anticipated contracts as well. While the Company continues to assess the potential impacts of the new standard, including the areas described above, the Company cannot reasonably estimate quantitative information related to the impact of the new standard on its financial statements at this time. Immaterial Revision to Prior Period Financial Statement The Company has revised the presentation of revenue and cost of sales to separately present those amounts that are associated with service and related activities from those amounts associated with product sales. This change does not impact the Company’s previously reported total revenues, gross margin, loss from operations or net loss for the periods presented.
