Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS New standards to be implemented In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new standard, Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, as amended, which will supersede nearly all existing revenue recognition guidance. Under ASU 2014-09, an entity is required to recognize revenue upon transfer of promised goods or services to customers in an amount that reflects the expected consideration received in exchange for those goods or services. ASU No. 2014-09 defines a five-step process in order to achieve this core principle, which may require the use of judgment and estimates, and also requires expanded qualitative and quantitative disclosures relating to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, including significant judgments and estimates used. The FASB has issued several amendments to the new standard, including clarification on accounting for licenses of intellectual property and identifying performance obligations. The amendments include ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606)-Principal versus Agent Considerations, which was issued in March 2016, and clarifies the implementation guidance for principal versus agent considerations in ASU 2014-09, and ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606)-Identifying Performance Obligations and Licensing, which was issued in April 2016, and amends the guidance in ASU No. 2014-09 related to identifying performance obligations and accounting for licenses of intellectual property. 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 new standard is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The Company does not plan to early adopt, and accordingly, it will adopt the new standard effective January 1, 2018. The Company currently plans to adopt using the modified retrospective approach. However, a decision regarding the adoption method has not been finalized at this time. The Company’s final determination will depend on a number of factors, such as the significance of the impact of the new standard on its financial results, system readiness, including that of software procured from third-party providers, and its ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary. The Company is in the initial stages of its evaluation of the impact of the new standard on its accounting policies, processes, and system requirements. The Company has made and will continue to make investments in systems to enable timely and accurate reporting under the new standard. While the Company continues to assess all potential impacts under the new standard, there is the potential for significant impacts to the timing of recognition of software licenses with undelivered features and professional services revenue related to service contracts with acceptance terms as well as contract acquisition costs, both with respect to the amounts that will be capitalized as well as the period of amortization. Under current industry-specific software revenue recognition guidance, the Company has historically concluded that it did not have vendor-specific objective evidence (“VSOE”) of fair value of the undelivered features relating to delivered software licenses, and accordingly, it has deferred entire revenue for such software licenses until the delivery of features. Professional services included in arrangements with acceptances have also been recognized on receipt of acceptance. The new standard, which does not retain the concept of VSOE, requires an evaluation of whether the undelivered features are distinct performance obligations and, therefore, should be separately recognized when delivered compared to the timing of delivery of software license. Professional services will generally be recorded as services are provided. Depending on the outcome of the Company’s evaluation, the timing of when revenue is recognized could change for future features and professional services under the new standard. As part of the Company’s preliminary evaluation, it has also considered the impact of the guidance in ASC 340-40, Other Assets and Deferred Costs; Contracts with Customers, and the interpretations of the FASB Transition Resource Group for Revenue Recognition (“TRG”) from their November 7, 2016 meeting with respect to capitalization and amortization of incremental costs of obtaining a contract. As a result of this new guidance, the Company is currently assessing if it will need to capitalize any costs of obtaining the contract, including additional sales commissions. Under the Company’s current accounting policy, it expenses the commission costs immediately as incurred. While the Company continues to assess the potential impacts of the new standard, including the areas described above, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on its financial statements at this time. In January 2016, the FASB issued an accounting standard update which requires equity investments to be measured at fair value with changes in fair value recognized in net income and simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. The accounting standard update also updates certain presentation and disclosure requirements. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2018 and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In February 2016, the FASB amended the existing accounting standard for lease accounting. Under this guidance, lessees and lessors should apply a “right-of-use” model in accounting for all leases (including subleases) and eliminate the concept of operating leases and off-balance sheet leases. This new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The new standard will be effective for the Company beginning in the first quarter of fiscal 2019 and early adoption is permitted. The Company is currently evaluating the methods and impact of adopting this new leases standard on its consolidated financial statements. In June 2016, the FASB issued new guidance that changes the impairment model for most financial assets and certain other instruments. For trade receivables and other instruments, the Company will be required to use a new forward-looking “expected loss” model. Additionally, credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses limited to the amount by which fair value is below amortized cost. The new guidance will be effective for the Company beginning in the first quarter of fiscal 2019 and early adoption is permitted. The Company is currently evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In August 2016, the FASB issued an accounting standard update that addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2018 and early adoption is permitted. The Company is currently evaluating the methods and impact of adopting the new accounting standard on its consolidated financial statements. In November 2016, the FASB issued an accounting standard update which requires companies to include restricted cash and restricted cash equivalents in its cash and cash equivalent balances in the statement of cash flows. Transfers between cash, cash equivalents, restricted cash, and restricted cash equivalents are no longer presented in the statement of cash flows. The new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2018 and early adoption is permitted. The adoption of this new guidance is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued an accounting standard update to simplify the test for goodwill impairment. It removes Step 2 of the goodwill impairment test and requires the assessment of fair value of individual assets and liabilities of a reporting unit to measure goodwill impairments. Goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2020 on a prospective basis, and early adoption is permitted. The Company is currently evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In March 2017, the FASB issued a new accounting standard to improve the presentation of net periodic pension cost and net periodic post-retirement benefit cost. This new standard will be effective for the Company beginning in the first quarter of fiscal 2018 and early adoption is permitted. The Company is currently evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In May 2017, the FASB issued a new accounting standard to clarify when to account for a change to the terms or conditions for a share-based payment award as a modification. It requires modification accounting only if the fair value, the vesting condition or the classification of the award changes as a result of the change in terms or conditions. This new standard will be effective for the Company beginning in the first quarter of fiscal 2018 and early adoption is permitted. The Company is currently evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. Standards Implemented In February 2015, the FASB issued an accounting standard update that changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The accounting standard update became effective for the Company beginning in the first quarter of fiscal 2017. The application of this accounting standard update did not have any impact on the Company's Consolidated Balance Sheet or Statement of Operations upon adoption. In July 2015, the FASB issued an accounting standard update that requires inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this accounting standard update beginning in the first quarter of fiscal 2017 and the adoption did not have a material impact on its consolidated financial statements. In March 2016, the FASB issued an accounting standard update to clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. The Company adopted this accounting standard update beginning in the first quarter of fiscal 2017 and the adoption did not have any impact on its consolidated financial statements. In March 2016, the FASB issued an accounting standard update for the accounting of share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The new standard eliminated the requirement to report excess tax benefits and certain tax deficiencies related to share-based payment transactions as additional paid-in capital. It also removes the requirement to delay recognition of a windfall tax benefit until it reduces current taxes payable. Under the new guidance, the benefit will be recorded when it arises, subject to normal valuation allowance considerations. The Company adopted this new accounting standard beginning in the first quarter of fiscal 2017 using a modified-retrospective transition method and recorded a cumulative effect of $4.6 million of additional gross deferred tax asset associated with shared-based payment and an offsetting valuation allowance of the same amount, therefore resulting in no net impact to the Company’s beginning retained earnings. Prior to January 1, 2017, stock-based compensation expense was recorded net of estimated forfeitures in the Company’s condensed consolidated statements of operations and, accordingly, was recorded for only those stock-based awards that the Company expected to vest. Upon the adoption of this accounting standard update, effective January 1, 2017, the Company changed its accounting policy to account for forfeitures as they occur. The change was applied on a modified retrospective approach with a cumulative effect adjustment of $69,000 to retained earnings as of January 1, 2017 (which increased the accumulated deficit). The implementation of this accounting standard update has no impact to the Company’s condensed statement of cash flows because the Company does not have any excess tax benefits from share-based compensation because its tax provision is primarily under full valuation allowance. No prior periods were recast as a result of this change in accounting policy. In October 2016, the FASB issued an accounting standard update which requires companies to recognize the income tax consequences of all intra-entity sales of assets other than inventory when they occur. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. The Company early adopted this accounting standard update during the first quarter of fiscal 2017 on a modified retrospective approach and recorded a cumulative-effect adjustment of $1.4 million to the retained earnings as of January 1, 2017 (which reduced the accumulated deficit). Correspondingly, in the first quarter of fiscal 2017, the Company recognized an additional $1.1 million of net deferred tax assets, after netting with $2.1 million of valuation allowance, and write off the remaining $0.3 million of unamortized tax expenses deferred under the previous guidance to provision for income taxes in the first quarter of fiscal 2017. In January 2017, the FASB issued an accounting standard update to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. The guidance will be effective for the Company beginning in the first quarter of fiscal 2018 on a prospective basis, and early adoption is permitted. The adoption of this new guidance is not expected to have a material impact on the Company’s consolidated financial statements.
