Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	1. Business Description: ClearOne, Inc., together with its subsidiaries (collectively, “ClearOne” or the “Company”), is a global market leader enabling conferencing, collaboration, and AV streaming solutions for voice and visual communications. The performance and simplicity of our advanced, comprehensive solutions offer unprecedented levels of functionality, reliability and scalability. Basis of Presentation: The fiscal year for ClearOne is the twelve months ending on December 31. The consolidated financial statements include the accounts of ClearOne and its subsidiaries. All significant inter-company accounts and transactions have been eliminated. These accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and are not audited. Certain information and footnote disclosures that are usually included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been either condensed or omitted in accordance with SEC rules and regulations. The accompanying condensed consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of June 30, 2019 and December 31, 2018, the results of operations for the three and six months ended June 30, 2019 and 2018, and the cash flows for the six months ended June 30, 2019 and 2018. The results of operations for the three and six months ended June 30, 2019 and 2018 are not necessarily indicative of the results for a full-year period. These interim unaudited condensed consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10 -K for the year ended December 31, 2018 filed with the SEC. Significant Accounting Policies: The significant accounting policies were described in Note 1 to the audited consolidated financial statements included in the Company’s annual report on Form 10 -K for the year ended December 31, 2018. There have been no changes to these policies during the six months ended June 30, 2019 that are of significance or potential significance to the Company except for the change in accounting for leases as described below. Recent accounting standard related to Leases: In February 2016, the FASB issued ASU 2016 - 02, Leases (“ASU 2016 - 02” ). This new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability 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 2016 - 02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018 - 11 which provides an alternative transition method that allows entities to apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company has adopted the requirements of ASU 2016 - 02 on January 1, 2019, the first day of fiscal year 2019, using the optional transition method. The Company elected to use certain practical expedient options, which allows an entity not to reassess whether any existing or expired contracts contain leases. There was an increase in assets of $2,966 and liabilities of $3,101 due to the recognition of the required right-of-use asset and corresponding liability for all lease obligations that are currently classified as operating leases with the difference of $135 related to existing deferred rent that reduced the ROU asset recorded. The standard did not have a material impact on our condensed consolidated statements of operations and comprehensive loss. Accounting Policy related to Leases: We determine if an arrangement is a lease at inception. Operating leases are included in operating lease - right of use (“ROU”) assets, accrued liabilities, and operating lease liability in our consolidated balance sheets. As of adoption of ASC 842 and as of June 30, 2019 and December 31, 2018, the Company was not party to finance lease arrangements. ROU assets represent our right to use an underlying asset for the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and operating lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. Under the available practical expedient, we account for the lease and non-lease components as a single lease component. Other recent accounting pronouncements: The Company has determined that other recently issued accounting standards will either have no material impact on its consolidated financial position, results of operations or cash flows, or will not apply to its operations.
