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, 2013.
	Nature of Operations
	PCTEL is a global leader in propagation and optimization solutions for the wireless industry. The Company develops and distributes innovative antenna and engineered site solutions and designs and develops software-based radios (scanning receivers) and provides related RF engineering services for wireless network optimization.
	PCTEL was incorporated in California in 1994 and reincorporated in Delaware in 1998. The principal executive offices are located at 471 Brighton Drive, Bloomingdale, Illinois 60108. The telephone number at that address is (630) 372-6800 and the Company’s website is www.pctel.com. The information within, or that can be accessed through the Company’s website, is not part of this report.
	Segment Reporting
	PCTEL operates in two segments for reporting purposes. The Company’s Connected Solutions segment includes its antenna and engineered site solutions. The Company’s RF Solutions segment includes its scanning receivers and related RF engineering services. Each of the segments 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. 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.
	Connected Solutions Segment
	PCTEL is a leading supplier of antennas for private network, public safety and government applications, and site solutions for both private and public network, data, and communications applications. PCTEL’s MAXRAD®, Bluewave™ and Wi-Sys™ antenna solutions include high-value YAGI, land mobile radio (“LMR”), Wi-Fi, GPS, in tunnel, subway, and broadband antennas (parabolic and flat panel). PCTEL’s Connected Solutions products include specialized towers, enclosures, fiber optic panels, and fiber jumper cables that are engineered into site solutions. The vertical markets into which the antenna and site solutions are sold include supervisory control and data acquisition (“SCADA”), health care, energy, smart grid, precision agriculture, indoor wireless, telemetry, offloading, and wireless backhaul. Growth for antenna and engineered 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 reseller, and original equipment manufacturer (“OEM”) providers.
	The Company established its current antenna and site solutions product portfolio with a series of acquisitions. In 2004, the Company acquired MAXRAD, Inc. (“MAXRAD”), as well as certain product lines from Andrew Corporation (“Andrew”), which established its core product offerings in Wi-Fi, LMR and GPS. Over the next several years the Company added additional capabilities within those product lines and additional served markets with the acquisition of certain assets from Bluewave Antenna Systems, Ltd (“Bluewave”) in 2008, and the acquisitions of Wi-Sys Communications, Inc (“Wi-Sys”) in 2009, Sparco Technologies, Inc. (“Sparco”) in 2010, and certain assets of TelWorx Communications LLC, TelWorx U.K. Limited, TowerWorx LLC, and TowerWorx International, Inc. (collectively “TelWorx”), in July 2012.

	There are many competitors for antenna products, as the market is highly fragmented. Competitors include Laird (Cushcraft, Centurion, and Antennex brands), Mobile Mark, Radiall/Larsen, Comtelco, Wilson, Commscope (Andrew products), Kathrein, among others. PCTEL seeks out product applications that command a premium for product performance and customer service, and avoid 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
	PCTEL is a leading supplier of high-speed, multi-standard, demodulating receivers and test and measurement solutions to the wireless industry worldwide. The Company’s SeeGull® scanning receivers, receiver-based products and CLARIFY® interference management solutions are used to measure, monitor and optimize cellular networks. The Company’s network engineering services group (“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. PCTEL develops and supports scanning receivers for LTE, EVDO, CDMA, WCDMA, GSM, TD-SCDMA, and WiMAX networks. The Company’s 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 are OEMs such as JDS Uniphase, Rohde and Schwarz, Anritsu, Digital Receiver Technology, and Berkley Varitronics.
	The Company established its scanning receiver product portfolio in 2003 with the acquisition of certain assets of Dynamic Telecommunications, Inc. (“DTI”). In 2009, the Company acquired the scanning receiver business from Ascom Network Testing, Inc. (“Ascom”) as well as the exclusive distribution rights and patented technology for Wider Network LLC (“Wider”) network interference products. The Company established its network engineering services business in 2011 with the acquisition of certain assets from Envision Wireless Inc. (“Envision”), an engineering services business based in Melbourne, Florida.
	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 September 30, 2014 and the condensed consolidated statements of operations, statements of comprehensive income (loss), and cash flows for the three and nine months ended September 30, 2014 and 2013, 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, 2013.
	On April 30, 2013, the Company divested all material assets associated with its PCTEL Secure, LLC subsidiary’s ProsettaCore™ technology to Redwall Technologies, LLC (“Redwall”), a development organization that specializes in mobile security, military and defense projects and systems, and critical national infrastructure. Under the terms of the agreement, Redwall acquired the server and device software (the “Software”), the underlying intellectual property, and complete development responsibility for the security products. At the closing of the divestiture, the Company received no upfront cash payment, but has the right to receive a royalty of 7% of the net sale price of each future sale or license of the Software and each provision of services related to the Software, if any. Under the agreement, royalties will not exceed $10.0 million in the aggregate. In accordance with accounting for discontinued operations, the consolidated financial statements separately reflect the results of PCTEL Secure as discontinued operations for the nine months ended September 30, 2013.
	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, 2013 (“the 2013 Form 10-K”). There were no changes in the Company’s significant accounting policies during the three and nine months ended September 30, 2014. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the 2013 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 2013 Form 10-K. The results for the operations for the period ended September 30, 2014 may not be indicative of the results for the period ending December 31, 2014.

	Foreign Currency Translation
	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, 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 gains/(losses) resulting from foreign currency transactions included in other income, net were $10 and ($10) for the three months ended September 30, 2014 and 2013, respectively, and were ($37) and ($26) for the nine months ended September 30, 2014 and 2013, respectively.
	Recent Accounting Guidance
	In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15, that requires management to assess if there is substantial doubt about an entity’s ability to continue as a going concern for each annual and interim period. If conditions or events give rise to substantial doubt, disclosures are required. The new accounting standard is effective as of December 31, 2016 and the Company does not expect it to have an impact on the financial statement disclosures.
	In May 2014, the FASB issued ASU 2014-09 that introduces a new five-step 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. 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. This standard is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the new guidance to determine the impact it will have on its consolidated financial statements.
	In April 2014, the FASB issued ASU 2014-08, which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations - that is, a major effect on the organization’s operations and financial results should be presented as discontinued operations. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, the ASU requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This update is effective in the first quarter of 2015. The Company does not expect the new guidance to have a material impact on its consolidated financial statements.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'

	2. Fair Value of Financial Instruments

	The Company follows accounting guidance for fair value measurements and disclosures. To measure fair value, the Company refers to a hierarchy that requires it to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instruments categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three levels of input that may be used to measure fair value are as follows:

	Level 1: inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

	Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.

	Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

	Cash equivalents are measured at fair value and investments are recognized at amortized cost in the Company’s financial statements. Accounts receivable and other investments are financial assets with carrying values that approximate fair value due to the short-term nature of these assets. Accounts payable is a financial liability with a carrying value that approximates fair value due to the short-term nature of these liabilities.

	4. Cash, Cash Equivalents and Investments

	The Company’s cash and investments consist of the following:



		September 30,		December 31,
		2014		2013
	Cash	$	18,717	$	19,734
	Cash equivalents		628		2,056
	Short-term investments		39,546		36,105

		$	58,891	$	57,895


	Cash and Cash equivalents

	At September 30, 2014, cash and cash equivalents included bank balances and investments with original maturities less than 90 days. At September 30, 2014 and December 31, 2013, the Company’s cash equivalents were invested in highly liquid AAA money market funds that are required to comply with Rule 2a-7 of the Investment Company Act of 1940. Such funds utilize the amortized cost method of accounting, seek to maintain a constant $1.00 per share price, and are redeemable upon demand. The Company restricts its investments in AAA money market funds to those invested 100% in either short-term U.S. government agency securities or bank repurchase agreements collateralized by these same securities. The fair values of these money market funds are established through quoted prices in active markets for identical assets (Level 1 inputs). The cash in the Company’s U.S. banks is insured by the Federal Deposit Insurance Corporation up to the insurable amount of $250.

	At September 30, 2014, the Company had $18.7 million in cash and $0.6 million in cash equivalents and at December 31, 2013, the Company had $19.7 million in cash and $2.1 million in cash equivalents. The Company had $1.2 million and $1.0 million of cash and cash equivalents in foreign bank accounts at September 30, 2014 and December 31, 2013, respectively. As of September 30, 2014, the Company has no intentions of repatriating the cash in its foreign bank accounts. If the Company decides to repatriate the cash in the foreign bank accounts, it may experience difficulty in doing so in a timely manner. The Company may also be exposed to foreign currency fluctuations and taxes if it repatriates these funds. The Company’s cash in its foreign bank accounts is not insured.

	7. PCTEL Secure

	PCTEL Secure designed Android-based, secure communication products. The Company learned through its marketing efforts for PCTEL Secure’s baseline product that its distribution channels had limited access to the target software markets, primarily U.S. government agencies. In January 2013 the Company engaged Wunderlich Securities, Inc. to evaluate strategic alternatives for PCTEL Secure, including a further search for a distribution entity that could take its baseline product to market.

	On April 30, 2013, the Company divested all material assets associated with PCTEL Secure’s ProsettaCore™ technology to Redwall Technologies, LLC (“Redwall”), a development organization that specializes in mobile security, military and defense projects and systems, and critical national infrastructure. Under the terms of the agreement, Redwall acquired the server and device software (the “Software”), the underlying intellectual property, and complete development responsibility for the related products. At the closing of the divestiture, the Company received no upfront cash payment, but the Company has the right to receive a royalty of 7% of the net sale price of each future sale or license of the Software and each provision of services related to the Software, if any. Under the agreement, royalties are capped at $10 million in the aggregate.

Acquisition of TelWorx Communications LLC	'

	8. Acquisition of TelWorx Communications LLC

	The Company, through its wholly-owned subsidiary PCTelWorx, Inc. (“PCTelWorx”), completed the acquisition of substantially all of the assets and the assumption of certain specified liabilities of TelWorx Communications LLC, TelWorx U.K. Limited, TowerWorx LLC and TowerWorx International, Inc. (collectively “TelWorx”), pursuant to an Asset Purchase Agreement dated as of July 9, 2012 among the Company, PCTelWorx, TelWorx and Tim and Brenda Scronce, the principal owners of TelWorx. PCTelWorx was merged with PCTEL, Inc. effective June 30, 2014. The fair value purchase price for TelWorx was $16.1 million, consisting of $16.0 million in cash paid at closing, $1.1 million of contingent consideration related to an indemnity holdback escrow and potential earn-out at fair value, net of $1.0 million cash recovered from Tim and Brenda Scronce in March 2013 pursuant to the working capital adjustment provisions of the Asset Purchase Agreement and the legal settlement described below.

	Following the closing of the acquisition, the Company’s management became aware of accounting irregularities with respect to the TelWorx financial statements, in part through an internal review conducted in connection with the calculation of post-closing purchase price adjustments and in part due to an anonymous tip received after the internal review began. With the oversight of the Audit Committee, management expanded its review into an internal investigation regarding these financial irregularities and outside counsel was retained to assist in the investigation. The Company’s outside counsel then retained a Big Four accounting firm to perform an independent forensic accounting investigation under counsel’s direction. The accounting irregularities in the TelWorx financial statements identified as a result of this investigation are believed to have been directed and/or permitted by management of TelWorx, principally Tim Scronce and those acting at his direction.

	The Company determined the amount of the corrections and the period in which they occurred through the forensic audit performed, which included tracing sales transactions to customer commitments and proof of delivery documents as well as reviewing the cost of sales records and aging of inventory at the acquisition date.

	The Company was authorized by the Board of Directors to seek restitution from the Telworx Parties and two other parties utilized by them in the acquisition. On March 27, 2013, the Company and the TelWorx Parties entered into a legal settlement over claims by the Company relating to the value of the acquisition and the accounting issues summarized above. The settlement had an aggregate fair value of $5.4 million, consisting of $4.3 million cash received, $0.6 million for the contingent consideration forfeited, and $0.5 million for the holdback escrow balance released. On September 30, 2014 the Company entered into a legal settlement with one of the other parties used by the TelWorx Parties in the acquisition for $0.1 million in cash. On October 10, 2014 the Company settled with the remaining other party for $0.8 million in cash. Both payments were received in October 2014.

	Restricted Stock – Service Based

	The Company grants shares of restricted stock as employee incentives as permitted under the Company’s 1997 Stock Plan. In connection with the grant of restricted stock to employees, the Company records deferred stock compensation representing the fair value of the common stock on the date the restricted stock is granted. Stock-based compensation expense is recorded ratably over the vesting period of the applicable shares. These grants vest over various periods, but typically vest over four years.

	The following table summarizes restricted stock activity for the nine months ended September 30, 2014:



							Weighted
							Average
							Grant Date
			Shares				Fair Value

	Unvested Restricted Stock Awards - December 31, 2013			543,021			$	6.59
	Shares awarded			145,505				8.28
	Shares vested			(371,749	)			6.57
	Shares cancelled			(3,175	)			8.28

	Unvested Restricted Stock Awards - September 30, 2014			313,602			$	7.38

	The intrinsic value of service-based restricted shares that vested during the three months ended September 30, 2014, and 2013, was $25 and $67, respectively. The intrinsic value of service-based restricted shares that vested during the nine months ended September 30, 2014, and 2013, was $3.2 million, and $2.7 million, respectively.

	At September 30, 2014, total unrecognized compensation expense related to restricted stock was approximately $1.3 million, net of forfeitures to be recognized through 2018 over a weighted average period of 1.7 years.

	Restricted Stock Units – Service Based

	The Company grants restricted stock units as employee incentives as permitted under the Company’s 1997 Stock Plan. Employee restricted stock units are time-based awards and are amortized over the vesting period. At the vesting date, these units are converted to shares of common stock. These units vest over various periods, but typically vest over four years. The fair value of the restricted stock units issued is based on the Company’s stock price on the date the restricted stock units are granted.



	The following table summarizes the restricted stock unit activity during the nine months ended September 30, 2014:



						Weighted
						Average
						Grant Date
		Shares				Fair Value

Unvested Restricted Stock Units - December 31, 2013			6,325			$	6.7
Units awarded			1,500				8.77
Units vested			(3,225	)			6.56

Unvested Restricted Stock Units - September 30, 2014			4,600			$	7.47

The intrinsic value of service-based restricted stock units that vested and issued as shares during the nine months ended September 30, 2014 and 2013 was $27 and $28, respectively. No units vested during the three months ended September 30, 2014 and 2013.

As of September 30, 2014, the unrecognized compensation expense related to the unvested portion of the Company’s restricted stock units was approximately $21, to be recognized through 2018 over a weighted average period of 1.5 years.

Stock Options

The Company grants stock options to purchase common stock for incentive purposes. The stock options contain exercise prices no less than the fair value of the Company’s stock on the grant date and typically vest in installments over a period of four years. Stock options may be exercised at any time prior to their expiration date or within ninety days of termination of employment, or such shorter time as may be provided in the related stock option agreement. Prior to 2010, the Company primarily granted stock options with a ten year life. Beginning with options granted in July 2010, the Company grants stock options with a seven year life.

The fair value of each unvested option was estimated on the date of grant using the Black-Scholes option valuation model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility and expected option life. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the existing models may not necessarily provide a reliable single measure of the fair value of the employee stock options.

The following table summarizes the stock option activity for the nine months ended September 30, 2014:



						Weighted
						Average
		Options				Exercise
		Outstanding				Price

Outstanding at December 31, 2013			1,461,559			$	8.4
Granted			19,550				8.21
Retention stock rights converted to stock options			207,236				7.16
Exercised			(41,841	)			7.22
Expired or Cancelled			(243,110	)			10.98
Forfeited			(7,944	)			7.83

Outstanding at September 30, 2014			1,395,450			$	7.8

Exercisable at September 30, 2014			681,693			$	8.41

During the nine months ended September 30, 2014 the Company issued 19,550 stock options with a weighted average grant date fair value of $2.21.



The Company calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model using the following assumptions at September 30:



		September 30,
		2014				2013
Dividend yield			2.2	%			1.6	%
Risk-free interest rate			0.5	%			0.2	%
Expected volatility			34	%			51	%
Expected life (in years)			5.2				4.6

The dividend yield rate was calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate was based on the U.S. Treasury yields with remaining term that approximates the expected life of the options granted. The Company calculates the volatility based on a five-year historical period of the Company’s stock price. The Company incorporates a forfeiture rate based on historical data in the expense calculation. The expected life used for options granted is based on historical data of employee exercise performance. The Company records expense based on the grading vesting method.

During the nine months ended September 30, 2014, the Company received proceeds of $0.3 million from the exercise of 41,841 options. The intrinsic value of these options exercised was $55.

In March 2014, in accordance with the plan documents, the Company awarded an additional 24,736 stock option rights to executive employees under the 2013 LTIP. These awards were earned based on 2013 performance criteria. In March 2014, the total stock option rights earned under the 2013 LTIP were converted to stock options that vest between two and four years from the April 2013 grant date.

As of September 30, 2014, the unrecognized compensation expense related to the unvested portion of the Company’s stock options was approximately $1.0 million, net of estimated forfeitures, to be recognized through 2018 over a weighted average period of 1.3 years.

The range of exercise prices for options outstanding and exercisable at September 30, 2014 was $5.50 to $11.00. The following table summarizes information about stock options outstanding under all stock plans at September 30, 2014:

Performance-based Equity Awards

In March 2014, the Company’s Board of Directors approved the 2014 Long-Term Incentive Plan (“2014 LTIP”) and the LTIP award agreements were completed in April 2014. Under the LTIP, shares are earned by certain executive employees based upon achievement of revenue goals over a four year period with a penalty if certain profit levels are not maintained. The four-year period is divided into two interim periods (each an “Interim Period”), the first of which will end at December 31, 2015 and the second of which will end at December 31, 2017. The number of shares that can be earned at threshold and target are 190,000 and 380,000, respectively. Stock compensation expense is amortized over the performance period for these awards based on estimated achievement of the goals. The Company amortized $0.2 million and $0.5 million for the performance awards during the three and nine months ended September 30, 2014, respectively.

Employee Stock Purchase Plan (“ESPP”)

The ESPP enables eligible employees to purchase common stock at the lower of 85% of the fair market value of the common stock on the first or last day of each offering period. Each offering period is approximately nine months. The Company received proceeds of $0.3 million from the issuance of 49,063 shares under the ESPP in February 2014 and received proceeds of $0.3 million from the issuance of 61,230 shares under the ESPP in February 2013. The Company received proceeds of $0.3 million from the issuance of 51,545 shares under the ESPP in August 2014 and received proceeds of $0.3 million from the issuance of 51,735 shares under the ESPP in August 2013.

Based on the 15% discount and the fair value of the option feature of this plan, this plan is considered compensatory. Compensation expense is calculated using the fair value of the employees’ purchase rights under the Black-Scholes model.

The Company calculated the fair value of each employee stock purchase grant on the date of grant using the Black-Scholes option-pricing model using the following assumptions:



		September 30,
		2014				2013
Dividend yield			2.2	%			1.7	%
Risk-free interest rate			0.3	%			0.3	%
Expected volatility			38	%			51	%
Expected life (in years)			0.5				0.5

The dividend yield rate was calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate was based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options granted. The dividend yield rate is calculated by dividing the Company’s annual dividend by the closing price on the grant date. The Company calculates the volatility based on a five-year historical period of the Company’s stock price. The expected life used is based on the offering period.

In June 2014, the Company’s shareholders approved an amended and restated ESPP. Under the restated ESPP, the number of shares authorized for issuance was increased by 750,000. In addition, the expiration date of the ESPP was modified from March 2017 to the date that all shares authorized have been granted.

Employee Withholding Taxes on Stock Awards

For ease in administering the issuance of stock awards, the Company holds back shares of vested restricted stock awards and short-term incentive plan stock awards for the value of the statutory withholding taxes. For each individual receiving a share award, the Company redeems the shares it computes as the value for the withholding tax and remits this amount to the appropriate tax authority. The Company paid $1.0 million for withholding taxes related to stock awards during the nine months ended September 30, 2014 and 2013, respectively.

Stock Repurchases

All share repurchase programs are authorized by the Company’s Board of Directors and are announced publicly. On March 18, 2013, the Company’s Board of Directors approved a share repurchase program for up to $5.0 million. On May 6, 2014, the Board of Directors of the Company extended this stock buyback program through September 2014. During the three months ended September 30, 2014, no shares were repurchased. During the nine months ended September 30, 2014, 215,650 shares were repurchased at an average price of $7.66. The Company repurchased 59,510 shares at an average price of $7.31 during the year ended December 31, 2013. As of September 30, 2014, there are no active share repurchase programs.

	Executive Deferred Compensation Plan

	Through December 2013, the Company provided an Executive Deferred Compensation Plan (“EDCP”) for executive officers, senior managers and directors. Under the EDCP, the executives could select to defer up to 50% of salary and up to 100% of cash bonuses. In addition, the Company provided a 4% matching cash contribution which vests depending upon the number of completed years of participation in the EDCP. The Company funded the obligation related to the EDCP with corporate-owned life insurance policies. The executive had a choice of investment alternatives from a menu of mutual funds offered by the insurance company. In November 2012, the Company’s Board of Directors authorized the termination of the EDCP and on December 27, 2013, the plan was terminated. The funds at the life insurance company were remitted to the Company and subsequently invested by the Company to fund the obligation. Each participant will receive the value of his or her account in January 2015. Upon separation of employment earlier than January 2015, a participant will receive the value of his or her account in accordance with the provisions of the plan. Because the funds from the insurance company were received in January 2014, $1.9 million was included in prepaid assets and other receivables on the balance sheet at December 31, 2013. At September 30, 2014, the value of the Company’s investment account to fund EDCP obligations was $2.0 million, included in cash equivalents and short-term investments in the consolidated balance sheets. At September 30, 2014 and December 31, 2013, the deferred compensation obligation was $2.0 million and $1.9 million, included in accrued liabilities and long-term liabilities, respectively, in the consolidated balance sheets.

TelWorx Settlement

On March 27, 2013, the Company, its wholly-owned subsidiary PCTelWorx, Inc. (“PCTelWorx”), and the TelWorx Parties (as defined below) entered into an Amendment (the “Amendment”) to the Asset Purchase Agreement dated July 9, 2012 (the “Original Agreement), among the Company, PCTelWorx, Ciao Enterprises, LLC f/k/a TelWorx Communications, LLC and certain of its affiliated entities (collectively, the “TelWorx Entities”) and Tim and Brenda Scronce (“Sellers” and collectively with the TelWorx Entities, the “TelWorx Parties”), as part of a settlement arrangement relative to PCTelWorx’ s acquisition of substantially all of the assets and the assumption of certain specified liabilities of the TelWorx Entities on July 9, 2012 (the “Acquisition”).



As disclosed in the Company’s Form 8-K/A filed with the Securities and Exchange Commission (the “Commission”) on March 13, 2013, after completion of the Acquisition, the Company became aware of certain accounting irregularities with respect to the TelWorx Entities and the Company’s Board of Directors directed management to conduct an internal investigation. Based on the results of the Company’s investigation, the Company’s Board of Directors directed management to seek restitution from the TelWorx Parties, and after protracted negotiations and concurrent litigation, the parties entered into the Amendment and related settlement agreements to resolve their dispute.

The following is a summary of the material terms of the Amendment:


	•	the TelWorx Parties paid the Company a cash payment of $4.3 million, which included $1.0 million pursuant to the working capital adjustment provisions of the Original Agreement;


	•	the TelWorx Parties forfeited all $1.5 million of the potential contingent consideration earnable under the Original Agreement, which had a fair value of $0.6 million, and which, if earned, would have been payable in the form of common stock of the Company;


	•	the TelWorx Parties forfeited the $0.5 million holdback escrow under the Original Agreement;


	•	the parties agreed to the elimination of all indemnification obligations provided for under the Original Agreement;


	•	the Company, PCTelWorx and the Sellers each agreed to execute mutual releases of all claims arising in connection with the dispute; and


	•	PCTelWorx acquired an option to terminate the facility lease in Lexington, North Carolina with Scronce Real Estate, LLC (which is controlled by Sellers) upon 180 days written notice.

The settlement had an aggregate fair value of $5.4 million, consisting of $4.3 million cash received, $0.6 million for the contingent consideration forfeited, and $0.5 million for the holdback escrow balance released. Approximately $1.0 million of the cash received was pursuant to the working capital adjustment provisions of the Original Agreement. The remaining $4.3 million settlement amount, consisting of $3.2 million cash and the release of the $0.6 million contingent consideration fair value and the $0.5 million release of the holdback escrow, was recorded as income in the quarter ended March 31, 2013, consistent with accounting for legal settlements.

As part of the Acquisition, PCTelWorx executed a five-year lease with Scronce Real Estate, LLC for the continued use of an operating facility and offices in Lexington, North Carolina, which provided for annual rental payments of approximately $0.2 million. In May 2013, the Company gave notice of its election to exercise its option to terminate the Lexington facility lease, with termination effective October 31, 2013.

The Company also engaged in efforts to seek further restitution from two other parties used by the TelWorx Parties in the acquisition. On September 30, 2014 the Company settled with one for $0.1 million in cash. The company recorded that settlement as income in the quarter ended September 30, 2014, consistent with accounting for legal settlements. On October 10, 2014 the Company settled with the other party for $0.8 million. The settlement will be recorded as income in the quarter ended December 31, 2014, consistent with accounting for legal settlements. Both payments were received in October 2014.

	12. Income Taxes

	The Company recorded income tax expense of $0.3 million for the nine months ended September 30, 2014. The tax expense for the nine months ended September 30, 2014 differed from the statutory rate of 34% primarily because the Company recorded a tax benefit of $0.8 million related to the reversal of a liability for uncertain income taxes. During the nine months ended September 30, 2014, the Company also recorded $0.5 million to additional paid in capital related to tax benefits for stock compensation. The Company recorded income tax expense for continuing operations of $1.8 million for the nine months ended September 30, 2013. The tax expense for the nine months ended September 30, 2013 differed from the statutory rate of 34% due to state income taxes.



	The Company’s valuation allowance against its deferred tax assets was $0.6 million at September 30, 2014 and December 31, 2013. On a regular basis, the Company evaluates the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment. The Company considers multiple factors in its evaluation of the need for a valuation allowance. The Company’s long-term forecasts continue to support the realization of its deferred tax assets. The Company’s domestic deferred tax assets have a ratable reversal pattern over 15 years. The carry forward rules allow for up to a 20 year carry forward of net operating losses (“NOL”) to future income that is available to realize the deferred tax assets. The combination of the deferred tax asset reversal pattern and carry forward period yields a 26.0 year average period over which future income can be utilized to realize the deferred tax assets.

	The Company’s gross unrecognized tax benefit was $0.9 million and $1.5 million at September 30, 2014 and December 31, 2013, respectively. The Company believes that is likely that approximately $0.1 million related to foreign income tax uncertainties will reverse in the fourth quarter 2014.

	The Company files a consolidated federal income tax return, income tax returns with various states, and foreign income tax returns in various foreign jurisdictions. The Company’s federal and state income tax years, with limited exceptions, are closed through 2007.

	The Company established its current antenna and site solutions product portfolio with a series of acquisitions. In 2004, the Company acquired MAXRAD, Inc. (“MAXRAD”), as well as certain product lines from Andrew Corporation (“Andrew”), which established its core product offerings in Wi-Fi, LMR and GPS. Over the next several years the Company added additional capabilities within those product lines and additional served markets with the acquisition of certain assets from Bluewave Antenna Systems, Ltd (“Bluewave”) in 2008, and the acquisitions of Wi-Sys Communications, Inc (“Wi-Sys”) in 2009, Sparco Technologies, Inc. (“Sparco”) in 2010, and certain assets of TelWorx Communications LLC, TelWorx U.K. Limited, TowerWorx LLC, and TowerWorx International, Inc. (collectively “TelWorx”), in July 2012.



	There are many competitors for antenna products, as the market is highly fragmented. Competitors include Laird (Cushcraft, Centurion, and Antennex brands), Mobile Mark, Radiall/Larsen, Comtelco, Wilson, Commscope (Andrew products), Kathrein, among others. PCTEL seeks out product applications that command a premium for product performance and customer service, and avoid 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

	PCTEL is a leading supplier of high-speed, multi-standard, demodulating receivers and test and measurement solutions to the wireless industry worldwide. The Company’s SeeGull® scanning receivers, receiver-based products and CLARIFY® interference management solutions are used to measure, monitor and optimize cellular networks. The Company’s network engineering services group (“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. PCTEL develops and supports scanning receivers for LTE, EVDO, CDMA, WCDMA, GSM, TD-SCDMA, and WiMAX networks. The Company’s 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 are OEMs such as JDS Uniphase, Rohde and Schwarz, Anritsu, Digital Receiver Technology, and Berkley Varitronics.

	The Company established its scanning receiver product portfolio in 2003 with the acquisition of certain assets of Dynamic Telecommunications, Inc. (“DTI”). In 2009, the Company acquired the scanning receiver business from Ascom Network Testing, Inc. (“Ascom”) as well as the exclusive distribution rights and patented technology for Wider Network LLC (“Wider”) network interference products. The Company established its network engineering services business in 2011 with the acquisition of certain assets from Envision Wireless Inc. (“Envision”), an engineering services business based in Melbourne, Florida.

	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	'
	Basis of Consolidation
	The condensed consolidated balance sheet as of September 30, 2014 and the condensed consolidated statements of operations, statements of comprehensive income (loss), and cash flows for the three and nine months ended September 30, 2014 and 2013, 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, 2013.
	On April 30, 2013, the Company divested all material assets associated with its PCTEL Secure, LLC subsidiary’s ProsettaCore™ technology to Redwall Technologies, LLC (“Redwall”), a development organization that specializes in mobile security, military and defense projects and systems, and critical national infrastructure. Under the terms of the agreement, Redwall acquired the server and device software (the “Software”), the underlying intellectual property, and complete development responsibility for the security products. At the closing of the divestiture, the Company received no upfront cash payment, but has the right to receive a royalty of 7% of the net sale price of each future sale or license of the Software and each provision of services related to the Software, if any. Under the agreement, royalties will not exceed $10.0 million in the aggregate. In accordance with accounting for discontinued operations, the consolidated financial statements separately reflect the results of PCTEL Secure as discontinued operations for the nine months ended September 30, 2013.
	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, 2013 (“the 2013 Form 10-K”). There were no changes in the Company’s significant accounting policies during the three and nine months ended September 30, 2014. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the 2013 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 2013 Form 10-K. The results for the operations for the period ended September 30, 2014 may not be indicative of the results for the period ending December 31, 2014.
Foreign Currency Translation	'

	Foreign Currency Translation

	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, 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 gains/(losses) resulting from foreign currency transactions included in other income, net were $10 and ($10) for the three months ended September 30, 2014 and 2013, respectively, and were ($37) and ($26) for the nine months ended September 30, 2014 and 2013, respectively.
Recent Accounting Guidance	'

	Recent Accounting Guidance

	In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15, that requires management to assess if there is substantial doubt about an entity’s ability to continue as a going concern for each annual and interim period. If conditions or events give rise to substantial doubt, disclosures are required. The new accounting standard is effective as of December 31, 2016 and the Company does not expect it to have an impact on the financial statement disclosures.

	In May 2014, the FASB issued ASU 2014-09 that introduces a new five-step 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. 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. This standard is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the new guidance to determine the impact it will have on its consolidated financial statements.

	In April 2014, the FASB issued ASU 2014-08, which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations - that is, a major effect on the organization’s operations and financial results should be presented as discontinued operations. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, the ASU requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This update is effective in the first quarter of 2015. The Company does not expect the new guidance to have a material impact on its consolidated financial statements.
