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. Our principal executive offices are located at 471 Brighton Drive, Bloomingdale, Illinois 60108. Our telephone number at that address is (630) 372-6800 and our website is www.pctel.com. The information within, or that can be accessed through our 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. Our SeeGull® scanning receivers, receiver-based products and CLARIFY® interference management solutions are used to measure, monitor and optimize cellular networks. PCTEL’s network engineering services (“NES”) Group provides value-added analysis of measured data collected during the optimization process. Revenue growth for these 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. Our scanning receiver products are sold primarily through test and measurement value added resellers and to a lesser extent directly to network operators. The engineering services are sold primarily to network infrastructure providers and cellular carriers. Competitors for these products are OEMs such as JDS Uniphase, Rohde and Schwarz, Anritsu, 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, we 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. In 2011, the Company purchased certain assets from Envision Wireless Inc. (“Envision”), an engineering services business based in Melbourne, Florida. The NES business focuses on the radio frequency (“RF”) issues pertaining to in-building coverage and capacity and its target market is relevant to our antenna and scanning receiver businesses. NES provides value-added analysis of collected data to public cellular carriers, network infrastructure providers, and real estate companies.

	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 March 31, 2014 and the condensed consolidated statements of operations, statements of comprehensive income (loss), and cash flows for the three months ended March 31, 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 three months ended March 31, 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 months ended March 31, 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 March 31, 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 losses resulting from foreign currency transactions included in other income, net were $39 and $11 for the three months ended March 31, 2014 and 2013, respectively.

	Recent Accounting Guidance

	In July 2013, the FASB issued ASU 2013-11, which provides that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. This standard was effective for us for fiscal years beginning after December 15, 2013. The adoption of this ASU did not have a significant impact on the Company’s 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:



		March 31,		December 31,
		2014		2013
	Cash	$	16,052	$	19,734
	Cash equivalents		423		2,056
	Short-term investments		39,694		36,105

		$	56,169	$	57,895


	Cash and Cash equivalents

	At March 31, 2014, cash and cash equivalents included bank balances and investments with original maturities less than 90 days. At March 31, 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 $250,000.



	At March 31, 2014, the Company had $16.1 million in cash and $0.4 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 $0.8 million and $1.0 million of cash and cash equivalents in foreign bank accounts at March 31, 2014 and December 31, 2013, respectively. As of March 31, 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.

	Investments

	At March 31, 2014 and December 31, 2013, the Company’s short-term investments consisted of pre-refunded municipal bonds, U.S. government agency bonds, AA or higher rated corporate bonds, and certificates of deposit classified as held-to-maturity. At March 31, 2014, the Company’s short-term investments also included mutual funds classified as available-for-sale and recorded at fair value. At March 31, 2014 the Company had invested $16.3 million in pre-refunded municipal bonds, $8.6 million in U.S. government agency bonds, $7.7 million in AA rated or higher corporate bonds, $5.2 million in certificates of deposit, and $1.9 million in mutual funds. The income and principal from the pre-refunded municipal bonds are secured by an irrevocable trust of U.S. Treasury securities. The bonds have original maturities greater than 90 days and mature in less than one year. The Company’s bonds are recorded at the purchase price and carried at amortized cost. The net unrealized gains were $12 at March 31, 2014. Approximately 16% and 5% of the Company’s bonds were protected by bond default insurance at March 31, 2014 and December 31, 2013, respectively.

	At December 31, 2013, the Company had invested $17.2 million in pre-refunded municipal bonds and taxable bond funds, $7.3 million in AA rated or higher corporate bond funds, $6.3 million in U.S. government agency bonds, and $5.3 million in certificates of deposit.

	The Company categorizes its financial instruments within a fair value hierarchy according to accounting guidance for fair value. The fair value hierarchy is described under the Fair Value of Financial Instruments in Note 2. For the Level 2 investments, the Company uses quoted prices of similar assets in active markets.

	Cash equivalents and Level 1 and Level 2 investments measured at fair value were as follows at March 31, 2014 and December 31, 2013:



		March 31, 2014								December 31, 2013

PCTEL Secure	'

	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.



	The consolidated financial statements separately reflect the PCTEL Secure operations as discontinued operations for all periods presented. Summary results of operations for the discontinued operations included in the condensed consolidated statement of operations are as follows:

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. 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 Scronces and other responsible parties. On March 27, 2013, the Company and the Scronces 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. The Company is still pursuing additional restitution from other responsible parties. See Footnote 11 – TelWorx Legal Settlement for full details.

	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 three months ended March 31, 2014:



			Shares				Weighted
							Average
							Grant Date
							Fair Value

	Unvested Restricted Stock Awards - December 31, 2013			543,021			$	6.59
	Shares awarded			105,950				8.48
	Shares vested			(319,200	)			6.41

	Unvested Restricted Stock Awards - March 31, 2014			329,771			$	7.37

	The intrinsic value of service-based restricted shares that vested during the three months ended March 31, 2014, and 2013, was $2.7 million, and $2.5 million, respectively.

	At March 31, 2014, total unrecognized compensation expense related to restricted stock was approximately $2.1 million, net of forfeitures to be recognized through 2018 over a weighted average period of 1.6 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 three months ended March 31, 2014:



			Shares				Weighted
							Average
							Grant Date
							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 - March 31, 2014			4,600			$	7.47



The intrinsic value of service-based restricted stock units that vested and issued as shares during the three months ended March 31, 2014 and 2013 was $27 and $28, respectively.

As of March 31, 2014, the unrecognized compensation expense related to the unvested portion of the Company’s restricted stock units was approximately $32, to be recognized through 2018 over a weighted average period of 1.6 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 three months ended March 31, 2014:



		Options				Weighted
		Outstanding				Average
						Exercise
						Price

Outstanding at December 31, 2013			1,461,559			$	8.4
Granted			7,500				8.69
Retention stock rights converted to stock options			207,236				7.16
Exercised			(27,270	)			7.28
Expired or Cancelled			(243,050	)			10.98
Forfeited			(3,250	)			8.18

Outstanding at March 31, 2014			1,402,725			$	7.79

Exercisable at March 31, 2014			495,374			$	8.88

During the three months ended March 31, 2014 the Company issued 7,500 stock options with a weighted average grant date fair value of $2.44.

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 March 31:



		March 31,
		2014				2013
Dividend yield			1.8	%			2	%
Risk-free interest rate			0.5	%			0.3	%
Expected volatility			39	%			52	%
Expected life (in years)			5.2				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 three months ended March 31, 2014, the Company received proceeds of $0.2 million from the exercise of 27,270 options. The intrinsic value of these options exercised was $34. In March 2014, in accordance with plan documents, the Company awarded an additional 24,736 stock option rights to executive employees under the 2013 LTIP. These options 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 March 31, 2014, the unrecognized compensation expense related to the unvested portion of the Company’s stock options was approximately $1.7 million, net of estimated forfeitures to be recognized through 2018 over a weighted average period of 1.4 years.

The range of exercise prices for options outstanding and exercisable at March 31, 2014 was $5.50 to $11.00. The following table summarizes information about stock options outstanding under all stock plans at March 31, 2014:



		Options Outstanding									Options Exercisable
Range of		Number				Weighted			Weighted-		Number		Weighted

$5.50 – $11.00			1,402,725				4.69		$	7.79		495,374	$	8.88

The intrinsic value and contractual life of the options outstanding and exercisable at March 31, 2014 were as follows:



		Weighted				Intrinsic
		Average				Value
		Contractual
		Life (years)
Options Outstanding			4.69			$	1,535
Options Exercisable			2.25			$	145

The intrinsic value is based on the share price of $8.73 at March 31, 2014.

Performance-based Equity Awards

In March 2014, the Company’s Board of Directors approved the 2014 Long-Term Incentive Plan (“2014 LTIP”). Under the LTIP, shares are earned by certain executive employees based upon achievement of four-year revenue goals 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. The LTIP award agreements were completed in April 2014.

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 six 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.



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:



		March 31,
		2014				2013
Dividend yield			1.8	%			1.9	%
Risk-free interest rate			0.3	%			0.2	%
Expected volatility			39	%			52	%
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.

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 and $0.9 million for withholding taxes related to stock awards during the three months ended March 31, 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. There were no share repurchases during the three months ended March 31, 2014. The Company repurchased 59,510 shares at an average price of $7.31 during the year ended December 31, 2013. At March 31, 2014, the Company had $4.6 million in share value that could still be repurchased under this program.

	The Company’s 401(k) plan covers all of the U.S. employees beginning the first of the month following the month they begin their employment. Under this plan, employees may elect to contribute up to 15% of their current compensation to the 401(k) plan, up to the statutorily prescribed annual limit. The Company may make discretionary contributions to the 401(k) plan. The Company made employer contributions of $194 and $145 to the 401(k) plan for the three months ended March 31, 2014 and 2013, respectively. The Company also contributes to various retirement plans for foreign employees. The Company made contributions to these plans of $82 and $61 for the three months ended March 31, 2014 and 2013, respectively.

	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. The participants will receive the value of his or her account in January 2015. Upon separation of employment earlier than January 2015, the executive 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 March 31, 2014, the value of the Company’s investment account to fund the obligation was $1.9 million, included in short-term investments in the consolidated balance sheets. At March 31, 2014 and December 31, 2013 the deferred compensation obligation was $1.9 million, included in accrued liabilities and long-term liabilities, respectively, in the consolidated balance sheets.

	Ending balance		$	296		$	277


	Restructuring

	During 2013, the Company integrated the TelWorx business with its Bloomingdale, IL operations. The Company moved kitting operations and order fulfillment to its Bloomingdale, Illinois facility from the Lexington, North Carolina facility. As part of the integration, the Company separated eighteen PCTelWorx employees between March and September 2013. The Company recorded $0.1 million as restructuring expense during the three months ended March 31, 2013 for employee severance costs.

	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.

The Company is also engaged in efforts to seek further restitution from the independent accountants that provided the 2010 and 2011 audited financial statements for TelWorx and the investment banking firm used by the TelWorx Parties. The Company cannot predict the total amount of restitution it will eventually obtain. In settling with the TelWorx parties, management considered the risks and expenses associated with protracted litigation as well as the consumption of Company resources that would otherwise be applied to operating activities.

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.

Income Taxes	'

	12. Income Taxes

	The Company recorded an income tax benefit of $0.1 million for the three months ended March 31, 2014. The tax expense for the three months ended March 31, 2014 differs from the statutory rate of 34% primarily because of state income taxes.

	The Company recorded an income tax expense of $1.1 million for the three months ended March 31, 2013. The tax expense for the three months ended March 31, 2013 differs from the statutory rate of 34% primarily because of state income taxes.

	The Company’s valuation allowance against its deferred tax assets was $0.6 million at March 31, 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 27.5 year average period over which future income can be utilized to realize the deferred tax assets.



	The Company’s gross unrecognized tax benefit was $1.5 million both at March 31, 2014 and December 31, 2013. The Company does not expect any of the potential benefits will be settled within the next twelve months. The Company believes that within the next twelve months uncertain tax positions may be resolved and statutes of limitations will expire, which could result in a decrease in the gross amount of unrecognized tax benefits of approximately $0.8 million.

	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’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. Our SeeGull® scanning receivers, receiver-based products and CLARIFY® interference management solutions are used to measure, monitor and optimize cellular networks. PCTEL’s network engineering services (“NES”) Group provides value-added analysis of measured data collected during the optimization process. Revenue growth for these 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. Our scanning receiver products are sold primarily through test and measurement value added resellers and to a lesser extent directly to network operators. The engineering services are sold primarily to network infrastructure providers and cellular carriers. Competitors for these products are OEMs such as JDS Uniphase, Rohde and Schwarz, Anritsu, 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, we 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. In 2011, the Company purchased certain assets from Envision Wireless Inc. (“Envision”), an engineering services business based in Melbourne, Florida. The NES business focuses on the radio frequency (“RF”) issues pertaining to in-building coverage and capacity and its target market is relevant to our antenna and scanning receiver businesses. NES provides value-added analysis of collected data to public cellular carriers, network infrastructure providers, and real estate companies.

	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 March 31, 2014 and the condensed consolidated statements of operations, statements of comprehensive income (loss), and cash flows for the three months ended March 31, 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 three months ended March 31, 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 months ended March 31, 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 March 31, 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 losses resulting from foreign currency transactions included in other income, net were $39 and $11 for the three months ended March 31, 2014 and 2013, respectively.
Recent Accounting Guidance	'

	Recent Accounting Guidance

	In July 2013, the FASB issued ASU 2013-11, which provides that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. This standard was effective for us for fiscal years beginning after December 15, 2013. The adoption of this ASU did not have a significant impact on the Company’s 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.
