Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. Basis of Presentation The interim unaudited Condensed Consolidated Financial Statements and related notes thereto have been prepared pursuant to generally accepted accounting principles in the United States of America, or GAAP, and the rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. The accompanying interim unaudited Condensed Consolidated Financial Statements and related notes thereto should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 (“2014 Annual Report”). Onvia had a wholly-owned subsidiary in Canada that was dissolved effective December 19, 2014; and there was no business activity in this subsidiary during the three and six month periods ended June 30, 2014. The wholly-owned subsidiary owned no assets or liabilities as of the date of dissolution. The information furnished is unaudited, but reflects, in the opinion of management, all adjustments, consisting of only normal recurring items, necessary for a fair presentation of the results for the interim periods presented. In addition, certain reclassifications of prior period balances have been made to conform to the current period presentation. Interim results are not necessarily indicative of results for a full year. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the fair value of stock-based compensation, allowance for doubtful accounts, capitalization of costs for internally developed software, recoverability of long-lived assets, including internally developed software, and the valuation allowance for Onvia’s net deferred tax assets. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ significantly from the Company’s estimates. In addition, any significant unanticipated changes in any of the Company’s assumptions could have a material adverse effect on its business, financial condition, and results of operations. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued guidance on the recognition of revenue from contracts with customers. Revenue recognition will 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. The guidance also requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented, or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application. The guidance was originally effective January 1, 2017 and early adoption was not permitted. In July 2015, the FASB approved a one-year deferral of the effective date to January 1, 2018, with an option of applying the standard on the original effective date. The company is currently evaluating the impact of the new guidance, the effective date and the method of adoption. |
