Summary of Significant Accounting Policies	3.Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of management, all normal recurring accruals and adjustments that are necessary for a fair presentation have been reflected. Intercompany transactions and balances have been eliminated in consolidation. The results reported in these unaudited condensed consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), but is not required for interim reporting purposes, has been condensed or omitted. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, filed with the SEC on March 30, 2016. On July 22, 2016, the Company effected a one-for-five reverse stock split. All share and per share information presented in these unaudited condensed consolidated financial statements has been retroactively adjusted to reflect the reverse stock split. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the condensed consolidated financial statements. Management regularly evaluates estimates and assumptions related to revenue recognition, valuations of liability warrants and the bifurcated derivative liability, allowances for doubtful accounts, warranty reserves, inventory valuation reserves, stock-based compensation, purchased intangible asset valuations and useful lives, goodwill, asset retirement obligations, and deferred income tax asset valuation allowances. These estimates and assumptions are based on current facts, historical experience and various other factors that believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced may differ materially and adversely from management’s original estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected. All discussions and amounts in the condensed consolidated financial statements and related notes for all periods presented relate to continuing operations only, unless otherwise noted. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. ASU No. 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605)”. ASU No. 2014-09 requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. In July 2015, the FASB finalized the delay of the effective date by one year, making the new standard effective for interim periods and annual periods beginning after December 15, 2017. Early adoption is permitted, but it is not permitted earlier than the original effective date. ASU No. 2014-09 provides for either full retrospective adoption or a modified retrospective adoption by which it is applied only to the most current period presented. The Company is currently in the process of evaluating the impact of the adoption of ASU No. 2014-09 on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. ASU No. 2014-15 defines management’s responsibility to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. It is effective for annual reporting periods ending after December 15, 2016, and for annual and interim reporting periods thereafter. Early adoption is permitted. The Company has not elected to early adopt, and it is currently in the process of evaluating the impact of the adoption of ASU No. 2014-15 on its consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory”. ASU No. 2015-11 changes the measurement principle for inventory from the “lower of cost or market” to “lower of cost and net realizable value.” Net realizable value is defined as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.” ASU No. 2015-11 eliminates the guidance that entities consider replacement cost or net realizable value less an approximately normal profit margin in the subsequent measurement of inventory when cost is determined on a first-in, first-out or average cost basis. It is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company has not yet determined whether it will elect to early adopt ASU 2015-11, and it is currently in the process of evaluating the impact of the adoption of ASU No. 2015-11 on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01 “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (Topic 825): ASU 2016-01 provides updated guidance that enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation, and disclosure. The standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods. Except for the early application guidance, early adoption of the amendments is not permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-01 on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. ASU No. 2016-02 supersedes the leasing guidance in Topic 840, Leases. Under the new guidance, lessees are required to recognize lease assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of ASU No. 2016-02 on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. ASU No. 2016-09 will change how companies account for certain aspects of share-based payments to employees. Entities will be required to recognize the income tax effects of awards in the statement of income when the awards vest or are settled, the guidance on employers’ accounting for an employee’s use of shares to satisfy the employer’s statutory income tax withholding obligation and for forfeitures is changing and the update requires companies to present excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity. ASU No. 2016-09 is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the condensed consolidated financial statements. Management regularly evaluates estimates and assumptions related to revenue recognition, valuations of liability warrants and the bifurcated derivative liability, allowances for doubtful accounts, warranty reserves, inventory valuation reserves, stock-based compensation, purchased intangible asset valuations and useful lives, goodwill, asset retirement obligations, and deferred income tax asset valuation allowances.

To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.

All discussions and amounts in the condensed consolidated financial statements and related notes for all periods presented relate to continuing operations only, unless otherwise noted.
