Basis of Presentation and Significant Accounting Policies [Text Block] | 1. Accounting Policies Basis of Presentation The unaudited interim Condensed Consolidated Financial Statements and related notes thereto have been prepared pursuant to generally accepted accounting principles in the United States of America, (“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 unaudited interim 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, 2015 (“2015 Annual Report”). 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. Interim results are not necessarily indicative of results for a full year. Reclassifications Certain prior year amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results of operations. Sales and marketing operating expenses of $511,000 and $1.2 million for the three and nine month periods ended September 30, 2015, respectively, have been reclassified as technology and development operating expenses to conform to current period presentation. The reclassification has no impact on net income/(loss) as presented on the unaudited Condensed Consolidated Statements of Operations. 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. During the third quarter of 2016, the Company determined it was appropriate to reduce the remaining estimated useful lives of certain internally developed software costs. See Note 7 below for further discussion of this reduction in remaining estimated useful lives and the corresponding impact to the results of operations. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance for revenue from contracts with customers, which provides a single comprehensive revenue recognition model to apply in determining how and when to recognize revenue. The core principle of the 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. When applying the new revenue model to contracts with customers the guidance requires five steps to be applied, which include: 1) identify the contract(s) with a customer, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also requires both quantitative and qualitative disclosures, which are more comprehensive than existing revenue standards. The disclosures are intended to enable financial statement users to understand the nature, timing and uncertainty of revenue and the related cash flow. This guidance will be effective for Onvia in the first quarter of 2018 and early adoption is permitted beginning in the first quarter of 2017. The Company is currently assessing the impact the guidance will have upon adoption. In November 2015, the FASB issued authoritative guidance amending the accounting for income taxes and requiring all deferred tax assets and liabilities to be classified as non-current on the balance sheet. The objective of the guidance is to simplify the presentation as current GAAP requires the Company to separate the deferred tax assets into current and noncurrent amounts. The FASB concluded that the current presentation does not benefit financial statement users because the classification does not align with the time period in which the deferred tax amounts are expected to be recovered. The guidance will be effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The guidance may be adopted either prospectively or retrospectively. The Company does not expect it to have a material impact on its consolidated financial statements upon adoption. In February 2016, the FASB issued authoritative guidance which requires lessees to recognize on the balance sheet assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current GAAP—which requires only capital leases to be recognized on the balance sheet—the new guidance will require both types of leases to be recognized on the balance sheet. The guidance will take effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. This guidance shall be applied at the beginning of the earliest period presented using the modified retrospective approach, which includes a number of practical expedients that an entity may elect to apply. Early application of the guidance is permitted. The Company is evaluating the adoption of this guidance and the potential effects on its consolidated financial statements. In March 2016, the FASB issued authoritative guidance on accounting for share-based payment transactions. The guidance makes several modifications related to the accounting for forfeitures, employer tax withholding on share-based compensation and the financial statement presentation of excess tax benefits or deficiencies and clarifies the statement of cash flows presentation for certain components of share-based awards. The standard is effective for interim and annual reporting periods beginning after December 15, 2016, although early adoption is permitted. The Company is currently assessing how the adoption of this standard may impact its consolidated financial statements. |
