Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. For further information, refer to the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Nature of Operations PCTEL, Inc. (“PCTEL”, the “Company”, “we”, “ours”, and “us”) delivers Performance Critical Telecom solutions. RF Solutions develops and provides test equipment, software and engineering services for wireless networks. The industry relies upon PCTEL to benchmark network performance, analyze trends, and optimize wireless networks. Connected Solutions designs and delivers performance critical antennas and site solutions for wireless networks globally. Our antennas support evolving wireless standards for cellular, private, and broadband networks. PCTEL antennas and site solutions support networks worldwide, including Supervisory Control and Data Acquisition (“SCADA”) for oil, gas and utilities, fleet management, industrial operations, health care, small cell and network timing deployment, defense, public safety, education, and broadband access. Segment Reporting PCTEL operates in two segments for reporting purposes, Connected Solutions and RF Solutions. The Company’s chief operating decision maker uses the profit and loss results through operating profit and identified assets for the Connected Solutions and RF Solutions segments to make operating decisions. Each segment has its own segment manager as well as its own engineering, sales and marketing, and operational general and administrative functions. All of the Company’s accounting and finance, human resources, IT and legal functions are provided on a centralized basis through the corporate function. The Company manages its balance sheet and cash flows centrally at the corporate level, with the exception of trade accounts receivable and inventory which is managed at the segment level. Each of the segment managers reports to and maintains regular contact with the chief operating decision maker to discuss operating activities, financial results, forecasts, or plans for the segment. Connected Solutions Segment Connected Solutions designs and delivers performance critical antennas and site solutions for wireless networks globally. The Company’s antennas and site solutions support networks worldwide, including SCADA for oil, gas and utilities, fleet management, industrial operations, health care, small cell and network timing deployment, defense, public safety, education, and broadband access. PCTEL's performance critical MAXRAD^® and Bluewave™ antenna solutions include high rejection and high performance GPS and GNSS products, the industry leading Yagi portfolio, mobile and indoor LTE, broadband, and LMR antennas and PIM-rated antennas for transit, in-building, and small cell applications. The Company leverages its design, logistics, and support capabilities to deliver performance critical site solutions into carrier, railroad, and utility applications. Revenue growth for antenna and site solutions is primarily driven by the increased use of wireless communications in these vertical markets. PCTEL’s antenna and site solution products are primarily sold through distributors, value-added resellers, and original equipment manufacturer (“OEM”) providers. There are many competitors for antenna products, as the market is highly fragmented. Competitors include Laird (Cushcraft, Centurion, and Antennex products), Mobile Mark, Radiall/Larsen, Comtelco, Wilson, Commscope (Andrew products), and Kathrein, among others. The Company seeks out product applications that command a premium for product performance and customer service, and avoids commodity markets. PCTEL maintains expertise in several technology areas in order to be competitive in the antenna engineered site solutions market. These include radio frequency engineering, mobile antenna design and manufacturing, mechanical engineering, product quality and testing, and wireless network engineering. RF Solutions Segment RF Solutions develops and provides performance critical test equipment, software, and engineering services for wireless networks. The industry relies upon PCTEL to benchmark network performance, analyze trends, and optimize wireless networks. SeeGull^® scanning receivers are used around the world for indoor and drive test applications, including baseline testing, acceptance testing, competitive benchmarking, spectrum clearing, troubleshooting, and network optimization. SeeGull scanning receivers provide high quality real-world RF measurements needed to build, tune, troubleshoot, and expand commercial wireless networks. The Company’s highly-trained engineering services team uses state-of-the-art test, measurement, and design tools to provide engineering services for in-building and outdoor networks. Our engineering services team (“NES”) provides wireless network testing, optimization, design, integration, and consulting services, with an emphasis on in-building distributed antenna systems (“DAS”). Revenue growth for the segment’s products and services is driven by the deployment of products based on new wireless technology and the need for wireless networks to be tuned and reconfigured on a regular basis. Scanning receiver products are sold primarily through test and measurement value-added resellers and to a lesser extent directly to network operators. Competitors for these products include OEMs such as JDS Uniphase, Rohde and Schwarz, Anritsu, Digital Receiver Technology, and Berkley Varitronics. On February 27, 2015, PCTEL acquired substantially all of the assets of, and assumed certain specified liabilities of, Nexgen Wireless, Inc. (“Nexgen”), pursuant to an Asset Purchase Agreement dated as of February 27, 2015. Nexgen provides a network analysis tool portfolio now known as SeeHawk^® Analytics, and engineering services. Nexgen's software product portfolio translates real-time network performance data into engineering actions to optimize operator performance and supports crowd-based, cloud-based data analysis to enhance network performance. Nexgen provides performance engineering, specialized staffing, and trend analysis for carriers, infrastructure vendors, and neutral hosts for 2G, 3G, 4G, and LTE networks. Refer to Note 7 for additional information on the Nexgen acquisition. PCTEL maintains expertise in several technology areas in order to be competitive in the scanning receiver and related engineering services market. These include radio frequency engineering, DSP engineering, manufacturing, mechanical engineering, product quality and testing, and wireless network engineering. Basis of Consolidation The condensed consolidated balance sheet as of June 30, 2016 and the condensed consolidated statements of operations, statements of comprehensive loss, and cash flows for the six months ended June 30, 2016 and 2015, respectively, are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The interim condensed consolidated financial statements are derived from the audited financial statements as of December 31, 2015. Certain prior year amounts have been reclassified for consistency with the current period presentation. The statements of operations for the three and six months ended June 30, 2015 include reclassifications between cost of revenues and operating expenses for intangible amortization. The Company reclassified $0.2 million and $0.3 million from operating expense to cost of revenues for the three and six months ended June 30, 2015, respectively. These reclassifications did not affect the operating loss or net income for the three and six months ended June 30, 2015. The unaudited interim condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been condensed or omitted. The significant accounting policies followed by the Company are set forth within the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (“the 2015 Form 10-K”). There were no changes in the Company’s significant accounting policies during the six months ended June 30, 2016. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the 2015 Form 10-K. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the 2015 Form 10-K. The results of operations for the period ended June 30, 2016 may not be indicative of the results for the period ending December 31, 2016. Foreign Operations The Company is exposed to foreign currency fluctuations due to its foreign operations and because products are sold internationally. The functional currency for the Company’s foreign operations is predominantly the applicable local currency. Accounts of foreign operations are translated into U.S. dollars using the exchange rate in effect at the applicable balance sheet date for assets and liabilities and average monthly rates prevailing during the period for revenue and expense accounts. Adjustments resulting from translation are included in accumulated other comprehensive income (loss), a separate component of shareholders’ equity. Gains and losses resulting from other transactions originally in foreign currencies and then translated into U.S. dollars are included in the condensed consolidated statement of operations. Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $19 and $21 for the three months ended June 30, 2016 and 2015, respectively. Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $35 and $27 for the six months ended June 30, 2016 and 2015, respectively. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU No. 2016-09 affects all entities that issue share-based payment awards to their employees. ASU No. 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows, including recognizing all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement rather than in additional paid-in capital. ASU No. 2016-09 is effective for financial statements issued for annual reporting periods beginning after December 15, 2016 and interim periods within those years. Earlier application is permitted. The Company is currently evaluating the impact the standard may have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which requires lessees to recognize assets and liabilities for the rights and obligations created by most leases on their balance sheet. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. ASU 2016-02 requires modified retrospective adoption for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Company is currently evaluating the impact the standard may have on its consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, to simplify the presentation of deferred income taxes. The amendments in this update require that deferred tax assets and liabilities be entirely classified as noncurrent within the statement of financial position. Effective December 31, 2015, the Company early adopted the balance sheet classification of deferred taxes on a prospective basis. The guidance requires deferred tax assets and liabilities to be classified as noncurrent rather than split between current and noncurrent. Approximately $1.8 million in current deferred tax assets was reclassified to long-term deferred tax assets at December 31, 2015. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” which introduces a new revenue recognition model in which 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. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The FASB has voted to approve a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017. The new accounting standard is expected to have an impact to the Company’s consolidated financial statements. The Company is currently evaluating the adoption method options and the impact of the new guidance on our consolidated financial statements.
