Basis of Presentation and Significant Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies The accompanying condensed consolidated financial statements as of December 31, 2016, and for the three and six months ended December 31, 2016 and 2015 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement have been included. The condensed consolidated balance sheet as of June 30, 2016 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2016. The results of operations for the three and six months ended December 31, 2016 are not necessarily indicative of the operating results to be expected for the full fiscal year or any future periods. Computation of Net Income (Loss) per Share Basic net income (loss) per share is determined by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is determined by dividing net income (loss) by the weighted average number of common shares used in the basic income (loss) per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive securities outstanding under the treasury stock method. Dilutive securities of 5.9 million weighted shares and 4.9 million weighted shares were not included in the computation of diluted net loss per share for the three and six months ended December 31, 2016, respectively, because such securities were anti-dilutive. Dilutive securities of 1.9 million weighted shares and 2.2 million weighted shares were not included in the computation of diluted net income per share for the three and six months ended December 31, 2015, respectively because such securities were anti-dilutive. Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable. As of December 31, 2016, all of the Company’s cash, cash equivalents and short-term investments were managed by multiple financial institutions. Accounts receivable are typically unsecured and are derived from revenue earned from customers. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. Accounts receivable from one value-added distributor accounted for 26% of total accounts receivable at December 31, 2016. At June 30, 2016 the same value-added distributor accounted for 42% of the total accounts receivable. Significant Accounting Policies The Company’s significant accounting policies are included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016. Recent Accounting Pronouncements Recent Accounting Standards or Updates Not Yet Effective In May 2014, the FASB issued ASU No. 2014-9 Revenue from Contracts with Customers (Topic 606) - an accounting standard that supersedes the revenue recognition requirements in Topic 605, Revenue Recognition. The core principle of the new guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. New disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. The effective date of the new standard was deferred by one year by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date. From March through December 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606):Identifying Performance Obligations and Licensing, ASU No. 2016-11, Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting, ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. These amendments are intended to improve and clarify the implementation guidance of Topic 606. This accounting guidance is effective for the Company in annual financial reporting periods beginning after December 15, 2017; early adoption is permitted for periods beginning after December 15, 2016. ASU No. 2014-9 may be applied retrospectively (a) to each reporting period presented or (b) with the cumulative effect in retained earnings at the beginning of the adoption period. The Company continues evaluating the method of adoption and the impact that the adoption of this accounting guidance may have on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. Under this ASU, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. The ASU defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. This accounting guidance is effective for the Company in annual financial reporting periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this accounting guidance may have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in Topic 840. This ASU requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. The guidance also requires qualitative and specific quantitative disclosures to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities, including significant judgments and changes in judgments. This accounting guidance is effective for the Company in annual financial reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this accounting guidance may have 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, which is intended to simplify several aspects of the accounting for share-based payment transactions, including certain income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This accounting guidance is effective for the Company in annual financial reporting periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this accounting guidance may have on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. This accounting guidance is effective for the Company in annual financial reporting periods beginning after December 15, 2019. Early adoption is permitted in annual financial reporting periods beginning after December 15, 2018. The Company is currently evaluating the impact that the adoption of this accounting guidance may have on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses the appropriate cash flow classification, including requirements to allocate certain components of these cash receipts and payments among operating, investing and financing activities for certain cash receipts and cash payments. The retrospective transition method, requiring adjustment to all comparative periods presented, is required unless it is impracticable for some of the amendments, in which case those amendments would be prospectively as of the earliest date practicable. The guidance is effective for financial reporting periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the impact that the adoption of this accounting guidance may have on its consolidated financial statements. In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements, which includes numerous technical corrections and clarifications to GAAP that are designed to remove inconsistencies in the board’s accounting guidance. Several provisions in this accounting guidance are effective immediately which did not have an impact on the Company’s consolidated financial statements. Additional provisions in this accounting guidance are effective for the Company in annual financial reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact that the adoption of the additional provisions in this accounting guidance may have on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies 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 is effective for annual financial reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of adopting this guidance.
