PA RT I

Item 1. B usiness.

We were incorporated under the laws of the state of Florida on August 22, 1989. We are in the business of innovating fundamental wireless hardware and software technologies and products. We have designed and developed a consumer distributed WiFi product line that is being marketed under the brand name Milo ® . We also design and develop proprietary radio frequency (“RF”) technologies for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States (“U.S.”) and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore our business plan includes enforcement of our intellectual property rights through patent infringement litigation and licensing efforts.

Based on the manner in which our management views and evaluates our operations, we have determined that our business currently operates under a single operating and reportable segment. Refer to our consolidated financial statements in Item 8 of this Annual Report for financial data including net losses from operations and total assets.

Recent Developments

Nasdaq Compliance

On August 11, 2017, we received a notice from the Listing Qualifications Department of Nasdaq stating that, for the last 30 consecutive business days, the market value of the our listed securities (“MVLS”) had been below the minimum of $35 million required for continued inclusion on the Capital Market under Nasdaq Listing Rule 5550(b)(2). In accordance with the notification, we were afforded 180 calendar days, or until February 7, 2018, to regain compliance. In order to regain compliance, our MVLS needed to remain at $35 million or more for a minimum of ten consecutive business days. On February 13, 2018, we received notification that, based upon our continued non-compliance, our securities would be subject to delisting from Nasdaq unless we timely requested a hearing before a Nasdaq Hearings Panel (the “Panel”). We requested a hearing before the Panel and currently, any delisting action has been stayed pending a decision from the Panel regarding our plan to regain compliance with the MVLS or other Nasdaq listing requirements and our request for an extension of time within which to regain compliance.

On March 22, 2018, we received a notice from Nasdaq stating that, for the last 30 consecutive business days, the closing bid price for our common stock had been below the minimum of $1.00 per share required for continued inclusion on Capital Market under Nasdaq Listing Rule 5550(a)(2). The notification letter stated that we would be afforded 180 calendar days (until September 18, 2018) to regain compliance with the minimum bid price requirement. In order to regain compliance, the bid price for shares of our common stock must close at $1.00 per share or more for a minimum of ten consecutive business days. The notification letter also states that in the event we do not regain compliance within the 180 day period, we may be eligible for additional time to the extent we meet the other listing requirements.

WiFi Product Introduction

In October 2017, we began selling a home and small business networking product line under the brand name, Milo ® . We currently offer our Milo products through online sales channels that include Amazon.com, Walmart.com, NeweggBusiness.com, and our own online store, www.milowifi.com. We also started a direct sales campaign targeting internet service providers for their inclusion of Milo products in offerings to their own customers.

ParkerVision v. Apple and Qualcomm (Middle District of Florida)

On March 8, 2018, the district court in the middle district of Florida denied a motion filed by Qualcomm to transfer the case to the southern district of California. The court also denied a motion filed by Apple to dismiss the case for improper venue. We are awaiting a revised court schedule for the proceedings, including the claim construction hearing that was originally scheduled for January 2018.

General Development of Business

Our core business since 2005 has been focused on the development of wireless technologies. Our technologies represent among other things, unique, proprietary methods for processing RF waveforms in wireless applications. Our technologies apply to both transmit and receive functions of transmitters, receivers, and transceivers as well as other related RF communications functions. A portion of our transmit technology is marketed as Direct2Power™, or d2p™, and enables the transformation of a baseband data signal to an RF carrier waveform, at the desired RF power output level, in a single unified operation. A portion of our receiver technology is marketed as Direct2Data™, or d2d™, and enables the direct conversion of an RF carrier to a baseband data signal, as well as enabling the direct conversion of a baseband signal to a modulated RF carrier signal. This technology is also referred to as energy transfer sampling down conversion for receivers and/or pulse-shaping up conversion for transmitters. We have developed these and a number of additional innovations which are protected by the intellectual property we have secured in various patent families for RF and related functions in RF-based communications.

For a number of years, we marketed our RF technologies and integrated circuit products for use in mobile products and applications. Our lack of tenure in the mobile handset industry coupled with the unique nature of our technology resulted in lengthy and intense technology evaluation and due diligence efforts by potential customers. Furthermore, in order to utilize our technology in a mobile handset application, we were reliant upon the provider of the baseband processor that generates the data to be transmitted or received by our RF chipsets. Although our technology is capable of interfacing with any baseband processor, the development of the interface between the baseband processor and our chipset requires a cooperative effort with the baseband provider. Accordingly, our marketing efforts were dependent on the activities of third parties. In addition, we believe our technology has been broadly infringed by others thereby reducing the competitive advantage of our technologies. We believe these factors hindered our sales efforts, particularly in markets for portable and consumer wireless applications such as mobile Smartphones and tables.

In 2011, through analysis of conference papers and tear down reports, we concluded that Qualcomm’s products were infringing our energy transfer sampling down conversion technology. Based on our belief that our technology is widely-deployed in the mobile handset market as a result of infringement of our patents, we began to more vigorously pursue an intellectual property licensing strategy which included enforcement actions. We filed a patent infringement lawsuit against Qualcomm in July 2011. Although this case resulted in a $173 million jury award in 2013 for Qualcomm’s infringement of several of our patents, the jury’s decision was ultimately overturned by the district court judge, a decision that was later upheld on appeal. Despite the courts’ decisions in this Qualcomm action, we continue to believe that certain of our technologies are broadly infringed and have wide-spread application in the industry.

From 2014 through 2017, we pursued licensing opportunities for our technologies, including through additional litigation where we deemed necessary to protect our patent rights. These efforts resulted in a patent license and settlement agreement with Samsung in 2016. We currently have ongoing patent infringement actions against Qualcomm, Apple and LG in both the U.S. and Germany as well as an action against HTC in the U.S. See “Legal Proceedings” in Note 13 to our consolidated financial statements included in Item 8 for a full discussion of our patent-related litigation activities. A significant portion of our litigation costs in 2017 and 2016 were funded under a secured contingent payment arrangement with Brickell Key Investments (“BKI”) and other contingent arrangements with our legal counsel. See “Liquidity and Capital Resources” in Item 8 for a full discussion of our litigation funding arrangements.

In addition to our patent enforcement activities, from 2013 through 2017, we also designed and developed products that included integrated circuits (“ICs”) based on our proprietary technologies as well end-user WiFi products aimed at the home and small business networking market. These product development efforts culminated in the launch of our Milo brand product line, which began selling in October 2017.

We anticipate our future business will include continued expansion of our Milo product line to include additional complimentary products as well as expanded features and functionality of the current products. Our expansion is expected to result both from internally-developed components, products and features as well as through the acquisition of complimentary business and/or product lines or through joint venture opportunities. We also anticipate a continued focus on licensing our intellectual property for incorporation into wireless devices designed and manufactured by others.

Our technology is capable of being incorporated for any of the mobile handset standards, as well as a variety of other communications protocols, including WiFi. By pursuing both licensing and product opportunities, we believe our technologies can be deployed in multiple markets that incorporate RF transmitters, receivers, and/or transceivers, including mobile handsets, tablets, femtocells, digital television, machine-to-machine, RF identification, cable modems, satellite communication, and infrastructure, among others. In order to secure proper compensation for the unauthorized use of our technologies by others, our licensing efforts also include enforcement actions against parties in some of these markets who we believe have already deployed products that infringe certain of our patented technologies.

Milo WiFi Products

Product Offerings

Our Milo-branded WiFi product line is a cost-effective networking system that enhances WiFi connectivity by effectively distributing the WiFi signal from existing routers and modems throughout a broader coverage area, eliminating WiFi dead zones and creating a more even distribution of data rates across the coverage area. Our product offering currently includes a two-unit system designed for coverage areas of up to 2,000 square feet and a three-unit system designed for coverage areas of up to 4,000 square feet. The Milo system can connect to an existing router via Ethernet cable. Alternatively, the system can connect to the router wirelessly through our BaseLink technology thus enabling the Milo user to eliminate redundancy of coverage from an existing router while also optimizing and maximizing the overall coverage area. Our embedded SmartSeek intelligence enables the Milo system to delegate signal communication across multiple radios in each Milo unit, thereby optimizing the network path for each unique environment. The systems are supported by easy-to-use mobile applications for both Apple and Android devices to enhance the overall customer experience.

Markets

Our goal is to provide a cost-effective product solution for inadequate WiFi coverage for consumers, small businesses and certain vertical markets, such as internet service providers. The growing number of internet-connected devices, including smart phones, laptops, tablets, Smart Home, and Internet of Things (“IoT”) devices such as Smart TVs, security cameras, thermostat controls, game consoles, etc., have increased the need for more robust and reliable networking solutions. Internet connections are being upgraded through high-speed broadband technologies in order to address more complex applications and rich multimedia content. Meanwhile, users want the convenience and flexibility of operating truly mobile devices. As a result, the need for more convenience, broader coverage, and increased reliability of residential and small business WiFi networks is increasing demand for wireless networking products.

Sales Channels

We began selling our Milo WiFi products in the U.S. in 2017 primarily through Amazon.com and our own online store. In 2018, we began expanding our online sales channels to include Walmart.com and NeweggBusiness.com. We will be further expanding our sales channels to include additional online retailers and wholesale distributors, including consignment arrangements. The wholesale distributors are expected to supply products to additional online retail channels and internet service providers. In addition, we are marketing our products and related services directly to internet service providers in the U.S. We also anticipate expansion of our sales channels into Canada and Europe in 2018. Amazon.com accounted for 10% or more of our net revenue for the year ended December 31, 2017.

Integrated Circuit Products

Our PV5870 IC is a modulator/demodulator component based on our proprietary technologies and targeted for markets that use less integrated RF transceivers than those used by the mobile handset market, such as infrastructure, industrial and military applications. We sell our PV5870 IC through a distribution relationship with RFMW, Ltd. Our sales of these ICs have been minimal to date.

In August 2017, we completed initial prototypes of our PV6870 IC, a complete single chip WiFi solution intended for sale to product manufacturers who want to incorporate WiFi wireless connectivity into their products. These ICs were developed in connection with third-parties and incorporate our RF technologies. Due to our limited resources, we decreased our investment commitment toward this product late in 2017 but expect to continue to pursue this design in 2018.

Production and Supply

We purchase several key components for our products from third-party suppliers, including contract manufacturers, on a purchase order basis. Our components generally have multiple sources of supply; however some components are designed specifically for our products and, in some cases, require specialty tooling. Our third-party suppliers generally purchase the materials for these components on our behalf on a purchase order basis. Lead times for our component products are generally 60 to 90 days without incurring additional costs for expediting. If our suppliers fail to satisfy our supply requirements, or we fail to adequately anticipate demand for our product, our ability to meet scheduled product deliveries would be impaired and we may lose sales and experience increased component costs. To mitigate our supply risk, we maintain an inventory of component and finished product inventory.

We have produced ICs through fabrication relationships with IBM Microelectronics (“IBM”) and Taiwan Semiconductor Manufacturing Company Limited (“TSMC”). In addition, we own the tooling for fabrication of our PV5870 IC. Given the limited sales to date of our PV5870 ICs, we do not anticipate additional fabrication of this product in the foreseeable future.

Competitive Position

We operate in a highly competitive industry against companies with greater brand recognition and substantially greater financial, technical, and sales and marketing resources. As a result, they may have larger distribution channels and greater reach to customers than we do.

Our WiFi products compete with WiFi networking products offered by companies such as Google, Belkin/Linksys, NetGear, Eero, and others. We also expect to face competition from service providers who bundle competing networking devices with their service offering if we are not the supplier of choice for those service providers. We believe the principal competitive factors in the markets for our networking products include product performance, ease-of-installation, price, customer support, brand and the breadth of sales channels. To compete, we must continue to invest in developing new products and features, expanding our sales channels and maintaining superior customer support.

Our technologies and IC products face competition from incumbent providers of transceivers, such as Broadcom, Fujitsu, Intel, MediaTek, NVidia, Qualcomm, STMicroelectronics, Marvell, Texas Instruments, and others, as well as incumbent providers of power amplifiers, including companies such as Anadigics, Qorvo, and Skyworks, among others. Each of our competitors, however, also has the potential of becoming a licensing or product customer for our technologies. To date, we are unaware of any competing or emerging RF technologies, other than infringing products that provide all the simultaneous benefits that certain of our technologies enable. Our unique technologies process RF carriers in a more optimal manner than prior traditional technologies, thereby allowing the creation of handsets and other products that have extended battery life, lower operating temperatures, more easily incorporate multiple air interface standards and frequencies in smaller form factors, improve operational performance, and reduce manufacturing costs. One or more of these benefits enable some of the key features that can be found in high volume wireless products. Our technologies provide such attractive benefits, in part, because of their unique operational and/or circuit architectures. The benefits our technologies enable include highly accurate transmission and reception of RF carriers that use less power than traditional architectures and components, thereby extending battery life, reducing heat and enabling certain size, cost, performance, and packaging advantages.

We believe the most significant hurdle to the licensing and/or sale of our technologies and products is the widespread use of certain of our technologies in infringing products produced by companies with significantly greater financial, technical and sales and marketing resources. We believe we can gain adoption and/or secure licensing agreements with unauthorized current users of one or more of our technologies, and therefore compete, based on a solid and defensible patent portfolio and the advantages enabled by our unique circuit architectures.

Patents and Trademarks

We consider our intellectual property, including patents, patent applications, trademarks, and trade secrets to be significant to our competitive positioning. We have a program to file applications for and obtain patents, copyrights, and trademarks in the U.S. and in selected foreign countries where we believe filing for such protection is appropriate to establish and maintain our proprietary rights in our technology and products. As of December 31, 2017, we had 198 U.S. and 36 foreign patents related to our RF technologies. In addition, we have approximately 30 U.S. and foreign patent applications pending. We estimate the economic lives of our patents to be fifteen to twenty years and our current portfolio of issued patents have expirations ranging from 2018 to 2034.

Research and Development

We have made significant investments in research and development in order to develop existing and new technologies in-house and to evaluate and test existing and new third-party technologies. Our research and development efforts have included the development and advancement of RF technologies, including the development of prototype ICs and related software interfaces, development and testing of our networking products, including the operating system software and mobile applications for those products, and the creation of test programs for quality control testing of our products. For the years ended December 31, 2017 and 2016, we spent approximately $4.3 million and $3.3 million, respectively, on Company-sponsored research and development activities.

Sales, Marketing and Customer Support

We support our sales channels through advertising, online promotions, and video testimonials and demonstrations. Our sales and marketing team, which includes both in-house and outside resources, focuses on brand development, product strategy, the new product introduction process, demand

assessment, and competitive analysis as well as channel expansion including direct sales to internet service providers. This team is also responsible for driving the traditional and digital marketing strategies and public relations.

Consumers often lack the technical knowledge and resources to implement advanced technologies. Therefore a customer-friendly installation experience is an important factor for this market. Our systems are designed with the consumer experience in mind. In addition, we have an internal, U.S.-based customer support group that provides support to those customers who have more complex environments or desire additional support. We provide customer support through a variety of channels including phone, chat, social media and email. Our support team also manages our technical support knowledge base for self-help customers and gathers customer feedback that is used to enhance our future product offerings. We believe an outstanding customer service experience is a differentiating factor for our products.

Employees

As of December 31, 2017, we had 45 full-time and 5 part-time employees, including 18 in research and development, 12 in sales, marketing and customer support, 7 in operations including sourcing and production, and 13 in executive management, finance, information systems and administration. We also utilize a number of temporary or contract staff to supplement our workforce. Our employees are not represented by any collective bargaining agreements and we consider our employee relations to be satisfactory.

Item 1A. Ris k Factors.

In addition to other risks and uncertainties described in this Annual Report, the following risk factors should be carefully considered in evaluating our business because such factors may have a significant impact on our business, operating results, liquidity and financial condition. As a result of the risk factors set forth below, actual results could differ materially from those projected in any forward-looking statements.

Our financial condition raises substantial doubt as to our ability to continue as a going concern.

Our independent registered public accounting firm has included in their audit opinion on our consolidated financial statements as of and for the year ended December 31, 2017 a statement with respect to substantial doubt regarding our ability to continue as a going concern. Note 2 to our consolidated financial statements included in Item 8 includes a discussion regarding our liquidity and our ability to continue as a going concern. Our consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. If we become unable to continue as a going concern, we may have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. The substantial doubt as to our ability to continue as a going concern may adversely affect our ability to negotiate reasonable terms with our suppliers and may adversely affect our ability to raise additional capital in the future.

We have had a history of losses which may ultimately compromise our ability to implement our business plan and continue in operation.

We have had losses in each year since our inception in 1989, and continue to have an accumulated deficit which, at December 31, 2017, was approximately $371.4 million. The net loss for 2017 was approximately $19.3 million. To date, our technologies and products have not produced revenues sufficient to cover operating, research and development and overhead costs. We will continue to make expenditures on patent protection and enforcement, research and development, marketing and sales, and general operations in order to secure and fulfill any contracts that we achieve for the sale of our products or technologies. Our revenues in 2018 may not bring us to profitability and our current capital resources are not sufficient to sustain our operations through 2018. If we are not able to generate sufficient revenues or obtain sufficient capital resources, we will not be able to implement our business plan or meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements a nd investors will suffer a loss in their investment. This may also result in a change in our business strategies.

We will need to raise substantial additional capital in the future to fund our operations. Failure to raise such additional capital may prevent us from implementing our business plan as currently formulated.

Because we have had net losses and, to date, have not generated positive cash flow from operations, we have funded our operating losses primarily from the sale of equity securities and through our secured contingent debt obligation. Our capital resources include cash, cash equivalents, including restricted cash equivalents, and available-for-sale securities of $1.4 million at December 31, 2017. Our business plan will continue to require significant expenditures for research and development, patent protection and enforcement, marketing and sales, and general operations. For the year ended December 31, 2017, we used $14.1 million in cash for operations which was funded primarily through the sale of equity securities. We expect the implementation of significant cost reduction measures in order to reduce our

cash needs may jeopardize our operations and future growth plans. O ur current capital resources will not be sufficient to meet our working capital needs for the twelve months after the issuance of our consolidated financial statements and we will require additional capital to fund our operations. Additional capital may be in the form of debt securities, the sale of equity securities, including common or preferred stock, additional litigation funding, or a combination thereof. Failure to raise additional capital will have a material adverse impact on our ability to achieve our business objectives.

The issuance of debt securities or additional equity securities may impose covenants or restrictions that create operational limitations or other obligations.

We will require additional capital to fund our operations and meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements . Financing, if any, may be in the form of debt or sales of equity securities, including common or preferred stock. The sale of equity securities, including common or preferred stock, may result in dilution to the current shareholders’ ownership and may be limited by the number of shares we have authorized and available for issuance. Debt instruments or the sale of preferred stock may result in the imposition of operational limitations and other covenants and payment obligations, any of which may be burdensome to us and may have a material adverse impact on our ability to implement our business plan as currently formulated.

Our ability to utilize our tax benefits could be substantially limited if we fail to generate sufficient income or if we experience an “ownership change.”

We have cumulative net operating loss carryforwards (“NOLs”) totaling approximately $328.4 million at December 31, 2017 which expire in varying amounts from 2018 to 2036. Our ability to fully recognize the benefits from those NOLs is dependent upon our ability to generate sufficient income prior to their expiration. In addition, our NOL carryforwards may be limited if we experience an ownership change as defined by Section 382 of the Internal Revenue Code. In general, an ownership change under Section 382 occurs if 5% shareholders increase their collective ownership of the aggregate amount of our outstanding shares by more than 50 percentage points over a relevant lookback period. In order to avoid limitations imposed by Section 382 of the Code, we may be limited in the amount of additional equity securities we are able to sell to raise capital. Accordingly, our desire to preserve our NOLs may cause us to forgo otherwise attractive funding opportunities.

Our litigation funding arrangements may impair our ability obtain future financing and/or generate sufficient cash flows to support our future operations.

We have funded much of our cost of litigation through contingent financing arrangements with a third-party funder and contingent fee arrangements with legal counsel. The repayment obligation to the third-party funder is secured by our assets until such time that we have repaid a specified minimum return. Furthermore, our contingent financing arrangements will result in reductions in the amount of net proceeds retained by us from litigation, licensing and other patent-related activities. For example, the third-party litigation funder is entitled to priority payment of at least the next $10.7 million in patent-related proceeds received by us. Thereafter, any remaining net proceeds will be prorated between us, our legal counsel and the third-party funder. The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent related proceeds sufficient to offset expenses and meet our contingent payment obligation. Failure to generate revenue or other patent-related proceeds sufficient to repay our contingent obligation may impede our ability to obtain additional financing which will have a material adverse effect on our ability to achieve our long-term business objectives.

Our litigation can be time-consuming, costly and we cannot anticipate the results.

Since 2011, we have spent a significant amount of our financial and management resources to pursue patent infringement litigation against third parties. We believe this litigation, and others that we may in the future determine to pursue, could continue to consume management and financial resources for long periods of time. There can be no assurance that our current or future litigation matters will ultimately result in a favorable outcome for us. In addition, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be predictive of the ultimate resolution of the matter. For example, we received a favorable jury decision in our litigation against Qualcomm, but that jury decision was overturned by the district court and the appellate court supported the district court decision. Unfavorable outcomes could result in exhaustion of our financial resources and could otherwise hinder our ability to pursue licensing and/or product opportunities for our technologies which would have a material adverse impact on our financial condition, results of operations, cash flows, and business prospects. We have contingent fee arrangements in place with others to reduce our litigation-related expenditures; however any litigation-based, or other patent related amounts collected by us will be subject to contingency payments to our legal counsel and other funding parties which will reduce the amount retained by us.

If our patents and intellectual property rights do not provide us with the anticipated market protections, our competitive position, business, and prospects will be impaired.

We rely on our intellectual property rights, including patents and patent applications, to provide competitive advantage and protect us from theft of our intellectual property. We believe that our patents are for entirely new technologies and that our patents are valid, enforceable and valuable. However, third parties have made claims of invalidity with respect to certain of our patents and other similar claims may be brought in the future. For example, in one of our litigations with Qualcomm Incorporated, the appellate court ruled that ten of eleven patent claims that were the subject of such action were invalid. If our patents are shown not to be as broad as currently believed, or are otherwise challenged such that some or all, of the protection is lost, we will suffer adverse effects from the loss of competitive advantage and our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial condition and business prospects. Furthermore, defending against challenges to our patents may give rise to material costs for defense and divert resources away from our other activities.

We are subject to outside influences beyond our control, including new legislation that could adversely affect our licensing and enforcement activities and have an adverse impact on the execution of our business plan.

Our licensing and enforcement activities are subject to numerous risks from outside influences, including new legislation, regulations and rules related to obtaining or enforcing patents. For instance, the U.S. has enacted sweeping changes to the U.S. patent system including changes that transition the U.S. from a “first-to-invent” to a “first to file” system and that alter the processes for challenging issued patents. To the extent that we are unable to secure patent protection for our future technologies and/or our current patents are challenged such that some or all of our protection is lost, we will suffer adverse effects to our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial position, results of operations and cash flows and our ability to execute our business plan.

Our industry is subject to rapid technological changes which if we are unable to match or surpass, will result in a loss of competitive advantage and market opportunity.

Because of the rapid technological development that regularly occurs in the wireless technology industry, we must continually devote substantial resources to developing and improving our technology and introducing new product offerings. For example, in fiscal years 2017 and 2016, we spent approximately $4.3 million and $3.3 million, respectively, on research and development and, we expect to continue to spend a significant amount in this area in the future. These efforts and expenditures are necessary to establish market share and, ultimately, to generate revenues. If another company offers better products or technologies, a competitive position or market window opportunity may be lost, and therefore our revenues or revenue potential may be adversely affected.

If our technologies and/or products are not commercially accepted, our developmental investment will be lost and our ability to do business will be impaired.

There can be no assurance that our research and development will produce commercially viable technologies and products, or that our technologies and products will be established in the market as improvements over current competitive offerings. If our existing or new technologies and products are not commercially accepted, the funds expended will not be recoverable, and our competitive and financial position will be adversely affected. In addition, perception of our business prospects will be impaired with an adverse impact on our ability to do business and to attract capital and employees.

We are reliant on component suppliers and contract manufacturers for adequate supply of components for our products, and the failure of our supply chain due to financial problems of suppliers, a shortage of adequate component supply or manufacturing capacity, or other factors that results in an increase in our costs or a delay in our ability to fill customer orders, could have an adverse impact on our business or operating results.

Our growth and ability to meet customer demand for our products depend, in part, on our ability to obtain timely deliveries of parts from our suppliers and contract manufacturers. We may in the future experience a shortage of certain component parts as a result of our own manufacturing issues, manufacturing or capacity issues at our suppliers or contract manufacturers, financial problems of our suppliers, or strong demand in the industry for those parts. During periods of shortages or delays, the price of components may increase, or the components may not be available at all. We may also encounter shortages if we do not accurately anticipate our needs. We may not be able to secure enough components at reasonable prices or of acceptable quality to build new products to meet customer demand. A reduction or interruption in supply, a significant increase in the price of one or more components, or a failure to appropriately adjust our requirements based on our business needs, could adversely impact our revenue and gross margins.

If we fail to properly estimate customer demand for our products, an oversupply of component parts could result in excess or obsolete inventory that could adversely affect our operating results.

Our operating results would be adversely affected if, anticipating greater demand for our products than actually develops, we commit to the purchase of more component parts than we need which is more likely to occur in a period of demand uncertainties such as during the rollout of a new product line like our Milo product line. In addition, component purchase commitments made by us in order to shorten lead times could also lead to excess and obsolete inventory charges. If we fail to anticipate customer demand properly, an oversupply of component parts could result in excess or obsolete components that could adversely affect our gross margins and operating results.

If we experience quality issues with our products, our competitive position, business and market opportunity may be impaired.

We produce products that incorporate leading-edge technology, including both hardware and software. Software typically contains bugs that can unexpectedly interfere with expected operations. There can be no assurance that our pre-shipment testing programs will be adequate to detect all defects, either ones in individual products or ones that could affect numerous shipments, which might interfere with customer satisfaction, reduce sales opportunities, or affect gross margins. If we have to replace certain components and provide remediation in response to the discovery of defects or bugs in products that we had shipped, there can be no assurance that such remediation would not have a material impact. An inability to cure a product defect could result in the failure of a product line, damage to our reputation, inventory costs, or product reengineering expenses, any of which could have a material impact on our revenue, margins, and net income.

We are highly dependent on Mr. Jeffrey Parker as our chief executive officer. If his services were lost, it would have an adverse impact on the execution of our business plan.

Because of Mr. Parker’s leadership position in the company and the respect he has garnered in both the industry in which we operate and the investment community, the loss of his services might be seen as an impediment to the execution of our business plan. If Mr. Parker was no longer available to the company, investors might experience an adverse impact on their investment. We maintain $5 million in key-employee life insurance for our benefit for Mr. Parker.

If we are unable to attract or retain key executives and other highly skilled employees, we will not be able to execute our current business plans.

Our business is very specialized, and therefore it is dependent on having skilled and specialized key executives and other employees to conduct our research, development and customer support activities. The inability to obtain or retain these key executives and other specialized employees would have an adverse impact on the research, development and technical customer support activities that our products require. These activities are instrumental to the successful execution of our business plan.

There can be no assurance that our common stock will continue to trade on the Nasdaq Capital Market or another national securities exchange.

On February 13, 2018, we received a letter from the Listing Qualifications Department of Nasdaq indicating that, based upon our continued non-compliance with Nasdaq Listing Rule 5500(b)(2), which requires an issuer to maintain a minimum market value of listed securities (“MVLS”) of $35 million, our securities would be subject to delisting from Nasdaq unless we timely requested a hearing before a Nasdaq Hearings Panel. We requested a hearing and any delisting action has currently been stayed pending a decision from the Nasdaq Hearings Panel regarding our plan to regain compliance with the MVLS or other Nasdaq listing requirements and our request for an extension of time within which to regain compliance. Also, on March 22, 2018, we received a notice from the Listing Qualifications Department of Nasdaq stating that, for the last 30 consecutive business days, the closing bid price for our common stock had been below the minimum of $1.00 per share required for continued inclusion on the Capital Market under Nasdaq Listing Rule 5550(a)(2). The notification letter stated that we would be afforded 180 calendar days (until September 18, 2018) to regain compliance with the minimum bid price requirement. In order to regain compliance, the bid price for shares of our common stock must close at $1.00 per share or more for a minimum of ten consecutive business days. Delisting could adversely affect our ability to raise additional financing through the public or private sale of our equity securities, would

significantly affect the ability of investors to trade our securities and would negatively affect the value and liquidity of our common stock. Delisting could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities.

Our outstanding options, warrants, and restricted share units may affect the market price and liquidity of the common stock.

At December 31, 2017, we had 21.2 million shares of common stock outstanding and had 1.9 million options, warrants, and restricted share units outstanding for the purchase and/or issuance of additional shares of common stock. Of these outstanding equity instruments, 1.1 million were exercisable as of December 31, 2017. The shares of common stock underlying these securities are registered for sale to the holder or for public resale by the holder. The amount of common stock available for the sales may have an adverse impact on our ability to raise capital and may affect the price and liquidity of the common stock in the public market. In addition, the issuance of these shares of common stock will have a dilutive effect on current shareholders’ ownership.

The price of our common stock may be subject to substantial volatility.

The trading price of our common stock has been and may continue to be volatile. Between January 1, 2016 and December 31, 2017 (after giving effect to the one-for-ten reverse stock split on March 30, 2016), the reported high and low sale prices for our common stock ranged between $8.18 and $1.02 per share. The price of our common stock may continue to be volatile as a result of a number of factors, some of which are beyond our control. These factors include, but are not limited to, developments in outstanding litigations, our performance and prospects, general conditions of the markets in which we compete, and economic and financial conditions. Such volatility could materially and adversely affect the market price of our common stock in future periods.

We do not currently pay dividends on our common stock and thus stockholders must look to appreciation of our common stock to realize a gain on their investments.

We do not currently pay dividends on our common stock and intend to retain our cash and future earnings, if any, to fund our business plan. Our future dividend policy is within the discretion of our board of directors and will depend upon various factors, including our business, financial condition, results of operations and capital requirements. We therefore cannot offer any assurance that our board of directors will determine to pay special or regular dividends in the future. Accordingly, unless our board of directors determines to pay dividends, stockholders will be required to look to appreciation of our common stock to realize a gain on their investment. There can be no assurance that this appreciation will occur.

We have a shareholder protection rights plan that may delay or discourage someone from making an offer to purchase the company without prior consultation with the board of directors and management, which may conflict with the interests of some of the shareholders.

On November 17, 2005, as amended on November 20, 2015, our board of directors adopted a shareholder protection rights plan which called for the issuance, on November 29, 2005, as a dividend, of rights to acquire fractional shares of preferred stock. The rights are attached to the shares of common stock and transfer with them. In the future the rights may become exchangeable for shares of preferred stock with various provisions that may discourage a takeover bid. Additionally, the rights have what are known as “flip-in” and “flip-over” provisions that could make any acquisition of the company more costly. The principal objective of the plan is to cause someone interested in acquiring the company to negotiate with the board of directors rather than launch an unsolicited bid. This plan may limit, prevent, or discourage a takeover offer that some shareholders may find more advantageous than a negotiated transaction. A negotiated transaction may not be in the best interests of the shareholders.

Provisions in our certificate of incorporation and by-laws could have effects that conflict with the interest of shareholders.

Some provisions in our certificate of incorporation and by-laws could make it more difficult for a third party to acquire control of us. For example, our board of directors is divided into three classes with directors having staggered terms of office, our board of directors has the ability to issue preferred stock without shareholder approval, and there are advance notification provisions for director nominations and submissions of proposals from shareholders to a vote by all the shareholders under the by-laws. Florida law also has anti-takeover provisions in its corporate statute.

Executive Overview

We are in the business of innovating fundamental wireless hardware and software technologies and products. We have designed and developed a consumer distributed WiFi product line that is being marketed under the brand name Milo. We also design and develop proprietary RF technologies for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the U.S. and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore our business plan includes enforcement of our intellectual property rights through patent infringement litigation and licensing efforts.

We have a growth strategy that includes wireless product development, manufacturing and sales; and intellectual property licensing and enforcement. Our longer-term growth strategy anticipates acquisition of, or other product ventures with, companies that have businesses that are synergistic with our products and technologies, particularly in the IoT space. We have significant net operating loss (“NOL”) carryforwards that we consider a key asset of our business as these NOLs can provide shelter to over $300 million of future earnings.

Our product development and marketing efforts are primarily focused on wireless networking products for homes and small businesses. Our Milo-branded WiFi product line is a cost-effective networking system that enhances WiFi connectivity by effectively distributing the WiFi signal from existing routers and modems throughout a broader coverage area, eliminating WiFi dead zones and creating a more even distribution of data rates across the coverage area. We currently sell our WiFi products through online retailers such as Amazon.com, Walmart.com, and NeweggBusiness.com, as well as through our own ecommerce web site. We also have a direct sales effort targeting internet service providers who provide WiFi equipment to their internet service customers. In 2018, we anticipate expansion of our product line as well as further expansion of our distribution channels. Our product expansion is expected to result both from internally-developed components, products, and features as well as through the acquisition of complimentary business and/or product lines or through joint venture opportunities. We anticipate expanding our sales channels to include additional online retailers and wholesaler distributors as well as geographic expansion planned for Canada and Europe.

We continue to aggressively pursue licensing opportunities with wireless communications companies that make, use or sell chipsets and/or products that incorporate RF. We believe there are a number of wireless communications companies that can benefit from the use of the RF technologies we have developed, whether through a license or, in certain cases, a joint product venture that may include licensing rights. From time to time, our licensing efforts require litigation in order to enforce and/or defend our intellectual property rights. Since 2011, we have been involved in patent infringement litigation against Qualcomm and others for the unauthorized use of our technology. In July 2016, we entered into a confidential patent license and settlement agreement with Samsung that resulted in the elimination of Samsung from all of our enforcement actions. Refer to “Legal Proceedings” in Note 13 to our consolidated financial statements included in Item 8 for a complete discussion of our legal proceedings. We have expended significant resources since 2011 on the enforcement and defense of our intellectual property rights.

Liquidity and Capital Resources

We used cash for operations of $14.1 million in 2017, representing a $0.3 million, or 2%, decrease from our use of cash for operations the same period 2016. This decrease in cash usage is primarily the result of a decrease in cash used for legal expenses associated with our patent infringement litigation, largely offset by increased cash usage related to inventory expansion and other costs related to the development and launch of our WiFi networking product line.

At December 31, 2017, we had a working capital deficit of approximately $0.2 million, an increase of approximately $0.3 million compared to the same period in 2016. This increase is largely due to an increase in product and component inventory for our WiFi products of approximately $0.9 million, an increase in our prepaid assets of approximately $0.3 million and an increase in our cash, cash equivalents and restricted cash equivalents of approximately $0.2 million, partially offset by an increase of approximately $1.2 million in our current liabilities.

We have incurred significant losses from operations and negative cash flows in every year since inception, largely as a result of our significant investments in developing and protecting our intellectual property. For the year ended December 31, 2017, we incurred a net loss of approximately $19.3 million and had an accumulated deficit of approximately $371.4 million. We had cash, cash equivalents, and available-for-sale securities totaling approximately $0.4 million and restricted cash equivalents of $1.0 million at December 31, 2017. Our independent registered public accounting firm has included in their audit report an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. See Note 2 to our consolidated financial statements included in Item 8 for a discussion of our liquidity and our ability to continue as a going concern.

We have utilized the proceeds from the sales of our equity securities and our contingent funding arrangement with BKI to fund our operations, including litigation costs. In 2016, we received an aggregate of $13 million from BKI, $11 million of which was designated for use in payment of legal fees and expenses in connection with certain patent infringement proceedings and $2 million of which was used for general working capital purposes. In December 2017, we received an additional $1 million in funding from BKI designated specifically for our German patent enforcement actions. BKI has a right to reimbursement and compensation from gross proceeds resulting from patent enforcement and other patent monetization actions. We repaid approximately $3.3 million of this contractual obligation in 2016 from proceeds received from patent licensing and settlement agreements. As of December 31, 2017, the contingent repayment obligation to BKI is recorded at its estimated fair value of approximately $15.9 million which represents management’s best estimate of the discounted cash flows to be paid to BKI. Although current working capital will not be used to repay this obligation, BKI is entitled to priority payment of 100% of at least the next $10.7 million in proceeds received by us from any patent-related action. Thereafter, BKI is entitled to a portion of additional patent-related proceeds up to at least a specified minimum return. In addition, funds received from patent-related activities may be subject to prorated contingent payments to legal counsel.

Although we have significantly reduced the working capital needed to fund litigation activities, the arrangements with outside counsel and BKI will reduce the net proceeds that we receive from patent-related activities, including litigation awards, settlements and licenses. After deduction of priority payments to BKI, any remaining net proceeds from specific patent enforcement actions will be prorated and prioritized between us, our legal counsel, and BKI based upon a number of factors including whether the proceeds are a result of a contingently-funded action, the magnitude, nature and timing of the proceeds received, and the contingent percentage agreed to between the parties. Based on our current outstanding legal proceedings, management expects that the contingent fees payable to others could range from 25% to 80% of the net proceeds remaining after priority reimbursement to BKI. These contingent fees are limited to specific actions and are expected to decline following successful completion of our current phase of licensing and patent enforcement activities.

In addition to the proceeds from our contingent funding arrangement, we received net proceeds from the sale of equity securities of $13.7 million for the year ended December 31, 2017. These proceeds included an aggregate of approximately $12.6 million in net proceeds from the sale of approximately 6.2 million registered shares of our common stock under at-market issuance (“ATM”) sales agreements. The shares were registered under a shelf registration statement filed with the SEC in November 2016 for the offering of up to $15 million in securities over a period of up to three years. As of December 31, 2017, we had remaining capacity under our ATM agreement for the sale of approximately $1.2 million in registered shares.

We also received net proceeds of approximately $1 million in 2017 under a common stock purchase agreement with Aspire Capital Fund, LLC (“Aspire”). Aspire has committed to purchase up to an aggregate of $20 million in shares of our common stock over the 30-month term of the agreement, subject to certain limitations. At December 31, 2017, Aspire had approximately $19 million remaining under the terms of the agreement.

Our ability to meet our liquidity needs for the twelve months after the issuance date of our consolidated financial statements is dependent upon one or more of (i) our ability to develop, market and sell existing and new products; (ii) our ability to successfully negotiate licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment obligations to BKI and legal counsel; and/or (iii) our ability to raise additional capital from the sale of equity securities or other financing arrangements. We anticipate that we will continue to invest in patent protection, research and development, and production, selling and marketing of our WiFi networking product line. We expect that revenue generated from product sales, patent enforcement actions, and technology licenses over the twelve months after the issuance of our consolidated financial statements will not be sufficient to cover our operating expenses. In the event we do not generate revenues, or other patent-asset proceeds, sufficient to cover our operational costs and contingent repayment obligation, we will be required to raise additional working capital through the sale of equity securities or other financing arrangements.

We are currently pursuing a two to three year financing transaction with third parties that may include debt, equity, in the form of common and preferred stock, or a combination thereof. There can be no assurance that we will be able to consummate a financing transaction with any of these third parties or that the terms of any such financing will be on terms and conditions that are acceptable. Until such time that we are able to consummate a longer-term financing transaction, we will continue to use the capacity available under our ATM and our common stock purchase agreement with Aspire to fund our short-term operations. The capital available to us under those financing vehicles is limited based on the remaining amounts available under our Shelf and limitations under Nasdaq rules with regards to the issuance of shares in excess of 19.99% of pre-transaction shares outstanding.

The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent-related proceeds sufficient to offset expenses and meet our contingent payment obligation. Failure to generate sufficient revenues, raise additional capital through debt or equity financings, and/or reduce operating costs could have a material adverse effect on our ability to meet our long-term liquidity needs and achieve our intended long-term business objectives.

Results of Operations for Each of the Years Ended December 31, 2017 and 2016

We use both generally accepted accounting principles (“GAAP”) and non-GAAP financial measures for assessing our consolidated results of operations. The non-GAAP measures we use include Adjusted Net Loss and Adjusted Net Loss per Share. These non-GAAP measures exclude the effect on net loss and net loss per share of (i) changes in fair value of our secured contingent payment obligation and (ii) share-based compensation expense. Share-based compensation is a non-cash expense item that is subject to significant fluctuation in value based on the volatility of the market price of our common stock, and the expense recognized on a GAAP basis is not necessarily indicative of the compensation realized by our executives, employees and non-employee directors. The change in fair value of our secured contingent payment obligation is subject to significant estimates and assumptions regarding future events and, similar to interest on long-term debt obligations, is a reflection of our cost of financing rather than our operating activities. Accordingly, we consider these non-GAAP measures to provide relevant supplemental information to assist investors in better understanding our operating results. These non-GAAP measures should not be considered a substitute for, or superior to measures of financial performance prepared in accordance with GAAP.

Refer to “Reconciliation of Non-GAAP Financial Measures” in this section for a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures for the years ended December 31, 2017 and 2016.

Revenues and Gross Margins

We reported licensing revenue of $0 and $4 million for the years ended December 31, 2017 and 2016, respectively as a result of a 2016 patent license and settlement agreement. The cost of sales for licensing reflects the amortization of the licensed patent portfolio. Although we anticipate additional licensing revenue to result from our licensing and patent enforcement activities, the amount and timing is highly unpredictable and there can be no assurance that we will achieve our anticipated results.

We reported product and service revenue of $0.1 million and $0.06 million for the years ended December 31, 2017 and 2016, respectively. For the year ended December 31, 2017, our product and service revenue was primarily comprised of sales of our WiFi networking product line that began shipping in October 2017. We recognized gross margin on our WiFi product sales of approximately 25%.

For the year ended December 31, 2016, our product and service revenue consisted primarily of engineering design services provided to third-parties and minimal IC product revenue. We recognized gross margin on our service revenue of approximately 36%. We ceased providing third-party services in 2016 in order to focus our resources on internal development of our WiFi product line. In addition, for the year ended December 31, 2017, we recorded a write down of excess IC inventory of approximately $0.1 million. We anticipate significant growth in our product revenue in 2018 as we expand our sales channels and our product offerings.

Research and Development Expenses

Research and development expenses consist primarily of engineering and related management and support personnel costs; fees for outside engineering design services which we use from time to time to supplement our internal resources; depreciation expenses related to certain assets used in product development; prototype production and materials costs for both ICs and end-user products; software licensing and support costs, which represent the annual licensing and support maintenance for engineering design and other software tools; and rent and other overhead costs for our engineering design facility. Personnel costs include share-based compensation which represents the grant date fair value of equity-based awards to our employees which is attributed to expense over the service period of the award.

Research and development costs were approximately $4.3 million for the year ended December 31, 2017 compared to approximately $3.3 million for the year ended December 31, 2016, representing an increase of approximately $1.0 million, or 30%. This increase is primarily the result of a $0.5 million increase in personnel and related overhead costs as a result of staff additions to support our recently launched networking product line. In addition, costs related to IC design and fabrication increased approximately $0.4 million as a result of development efforts towards our WiFi system on chip design.

The markets for our products and technologies are characterized by rapidly changing technology, evolving industry standards and frequent new product introductions. Our ability to successfully develop and introduce, on a timely basis, new and enhanced products and technologies will be a significant factor in our ability to grow and remain competitive. We expect to continue to invest a portion of our working capital in research and product development activities.

Selling, General, and Administrative Expenses

Selling, general and administrative expenses consist primarily of executive, director, sales and marketing, and finance and administrative personnel costs, including share-based compensation, costs incurred for advertising, insurance, shareholder relations and outside legal and professional services, including litigation expenses, and amortization and maintenance expenses related to our patent assets.

Our selling, general and administrative expenses were approximately $14.1 million for the year ended December 31, 2017, as compared to approximately $16.3 million for the year ended December 31, 2016, representing a decrease of approximately $2.2 million or 14% . This decrease is the result of a decrease in litigation fees and expenses of approximately $4.5 million, as the cost of discovery in our ITC and related actions were largely completed early in 2017. This decrease is offset by increases in personnel and related expenses of approximately $0.4 million, increases in advertising, product marketing and promotional expense of approximately $1.3 million, and increases in outside management consulting fees of approximately $0.3 million. The majority of these increases relate to personnel, advertising and other outside resources necessary for our WiFi product deployment.

Change in Fair Value of Contingent Payment Obligation

Our losses from the changes in fair value of our contingent payment obligation were approximately $0.7 million and $4.9 million for the years ended December 31, 2017 and 2016, respectively. We have elected to measure our secured contingent payment obligation at fair value which is based on significant unobservable inputs. We estimated the fair value of our secured contingent payment obligation using an income approach based on the estimated present value of projected future cash flows to be paid to BKI using a risk-adjusted discount rate. Changes in the significant unobservable inputs, which include estimates of the nature, timing and amount of projected future proceeds from patent-related activities, could result in significant increases or decreases in fair value from period to period.

Adjusted Net Loss and Adjusted Net Loss per Share

Adjusted net loss increased by approximately $1.9 million, or 13%, for the year ended December 31, 2017 compared to the same period in 2016. The increase in adjusted net loss is a result of the decrease in revenue from patent licensing and settlement agreements and increased costs related to the launch of our new product line, partially offset by our decreased litigation expenses. On a per share basis, our adjusted net loss per common share decreased by $0.25 per share, or 21%. This decrease is primarily the result of a 44% increase in our weighted average common shares outstanding, partially offset by the increase in our adjusted net loss.

Reconciliation of Non-GAAP Financial Measures

The following table presents a reconciliation of our net loss to the non-GAAP measure of adjusted net loss for the years ended December 31, 2017 and 2016, respectively:



(in thousands)	2017		2016
Net loss	$	(19,259)	$	(21,509)
Excluded items:
Share-based compensation		2,164		2,210
Change in fair value of contingent payment obligation		711		4,860
Adjusted net loss	$	(16,384)	$	(14,439)

The following table presents a reconciliation of our net loss per common share to the non-GAAP measure of adjusted net loss per common share for the years ended December 31, 2017 and 2016, respectively:



	2017		2016
Basic and diluted net loss per common share	$	(1.09)	$	(1.76)
Excluded items		0.16		0.58
Adjusted net loss per common share	$	(0.93)	$	(1.18)

Critical Accounting Policies

We believe that the following are the critical accounting policies affecting the preparation of our consolidated financial statements:

Inventory

Inventory is stated at the lower of actual cost, as determined under the first-in, first-out method, or estimated net realizable value. We review our inventory for estimated obsolescence or unmarketable inventory and write down inventory for the difference between cost and estimated market value based upon assumptions about future demand. Future demand is affected by market conditions, technological obsolescence, new products and strategic plans, each of which is subject to change.

Intangible Assets

Patents, copyrights and other intangible assets are amortized using the straight-line method over their estimated period of benefit. We estimate the economic lives of our patents and copyrights to be fifteen to twenty years. We estimate the economic lives of other intangible assets, including licenses, based on estimated technological obsolescence, to be two to five years, which is generally shorter than the contractual lives. Management evaluates the recoverability of intangible assets periodically and takes into account events or circumstances that may warrant revised estimates of useful lives or that may indicate impairment exists.

Secured Contingent Payment Obligation

We have accounted for our secured contingent repayment obligation as long-term debt. Our repayment obligations are contingent upon the receipt of proceeds from patent enforcement and/or patent monetization actions. We have elected to measure our secured contingent payment obligation at its fair value based on the variable and contingent nature of the repayment provisions. We have determined that the fair value of our secured contingent payment obligation falls within Level 3 in the fair value hierarchy which involves significant estimates and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows (see Note 16 to the consolidated financial statements included in Item 8). Actual results could differ from the estimates made. Changes in fair value, including the component related to imputed interest, are included in the consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligation.”

Revenue Recognition

We derive revenue from licensing of our intellectual property, settlements from patent infringement disputes, sales of products, and engineering services. The timing of revenue recognition and the amount of revenue recognized depends upon a variety of factors, including the specific terms of each arrangement and the nature of our deliverables and obligations. In general, we recognize revenue when there is persuasive evidence of an arrangement, the amounts are fixed and determinable and the collectability is reasonably assured.

Revenue from the sale of products is recognized at the time of shipment to the customer or when the other criteria for revenue recognition are met, if later. Unearned revenue generally consists of product inventory held by a distributor. Revenue from the sale of our products includes shipping and handling charged to the customer. Product revenue is recorded net of sales tax collected from customers, discounts, and actual and estimated future returns.

The consideration received from patent license and settlement agreements is allocated to the various elements of the arrangement to the extent the revenue recognition differs between the elements of the arrangement. Elements related to past and future royalties as well as elements related to settlement will be recorded as revenue in our consolidated statements of comprehensive loss when earned. We recognize revenues upon execution of a patent license and settlement agreement by both parties provided that the amounts are fixed and determinable, there are no significant undelivered obligations and collectability is reasonably assured. We do not recognize any revenue prior to the execution of an agreement as there is no reliable basis on which we can estimate the amounts related to the elements of the arrangement, or assess collectability. In addition, we do not recognize as revenue any consideration in the agreement that is contingent upon the occurrence of future events until such time that those future events occur.

Accounting for Share-Based Compensation

We calculate the fair value of share-based equity awards to employees, including restricted stock, stock options and restricted stock units, on the date of grant and recognize the calculated fair value as compensation expense over the requisite service periods of the related awards. The fair value of stock option awards is determined using the Black-Scholes option valuation model which requires the use of highly subjective assumptions and estimates including how long employees will retain their stock options before exercising them and the volatility of our common stock price over the expected life of the equity award. Changes in these subjective assumptions can materially affect the estimate of fair value of share-based compensation and consequently, the related amount recognized as expense in the consolidated statements of comprehensive loss.

Income Taxes

The provision for income taxes is based on loss before taxes as reported in the consolidated statements of comprehensive loss. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized. Our deferred tax assets exclude unrecognized tax benefits which do not meet a more-likely-than-not threshold for financial statement recognition for tax positions taken or expected to be taken in a tax return.

Off-Balance Sheet Transactions and Contractual Obligations

As of December 31, 2017, we had outstanding warrants to purchase 0.4 million shares of our common stock. The estimated grant date fair value of these warrants of approximately $0.8 million is included in shareholders’ (deficit) equity in our consolidated balance sheets. The outstanding warrants have an average exercise price of $2.21 per share and a weighted average remaining life of approximately three years (See “Common Stock Warrants” in Note 11 to the consolidated financial statements included in Item 8).

Our contractual obligations and commercial commitments at December 31, 2017 were as follows, in thousands (see “Lease Commitments” in Note 13 to the consolidated financial statements included in Item 8):



	Payments due by period
Contractual Obligations:	Total		1 year or less		2 – 3 years		4 – 5 years		After 5 years
Operating leases	$	1,092	$	372	$	375	$	345	$	-
Capital leases		5		2		3		-		-

Item 7A. Quantitat ive and Qualitative Disclosures about Market Risk.

Our cash equivalents and restricted cash equivalents, which are primarily highly liquid money market instruments, and our available-for-sale securities, which are mutual funds invested primarily in short-term municipal securities, are subject to market risk, including interest rate risk. Market risk is the risk of loss arising from adverse changes in market and economic conditions and is directly influenced by the volatility and liquidity in the markets in which the related underlying assets are traded. We are averse to principal loss and seek to ensure the safety and preservation of our funds by investing in market instruments with limited market risk. Accordingly, we do not believe there is any material market risk exposure with respect to our market instruments.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and

Shareholders of ParkerVision, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ParkerVision, Inc. and its subsidiary (“the Company”) as of December 31, 2017 and 2016 , and the related consolidated statements of comprehensive loss, shareholders (deficit) equity and cash flows for the years then ended , including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt About the Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has suffered recurring losses from operations and negative cash flows that raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. T he Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

PARKE RVISION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2017 and 2016

1. THE COMPANY AND NATURE OF BUSINESS

ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH (collectively “ParkerVision”, “we” or the “Company”) is in the business of innovating fundamental wireless hardware and software technologies and products. We have designed and developed a consumer distributed WiFi product line that is being marketed under the brand name Milo ® . We also design and develop our proprietary radio frequency (“RF”) technologies for use in semiconductor circuits for wireless communication products. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore our business plan includes enforcement of our intellectual property rights through patent infringement litigation and licensing efforts . We have determined that our business currently operates under a single operating and reportable segment.

2. LIQUIDITY AND GOING CONCERN

The accompanying consolidated financial statements as of and for the year ended December 31, 2017 were prepared assuming we will continue as a going concern, which contemplates that we will continue in operation and will be able to realize our assets and settle our liabilities and commitments in the normal course of business for a period of at least one year from the issuance date of these financial statements. These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that could result should we be unable to continue as a going concern.

We have incurred significant losses from operations and negative cash flows in every year since inception and have utilized the proceeds from the sales of our equity securities and our contingent funding arrangements with third-parties to fund our operations, including our litigation costs. For the year ended December 31, 2017, we incurred a net loss of approximately $19.3 million and negative cash flows from operations of approximately $14.1 million. At December 31, 2017, we had a working capital deficit of approximately $0.2 million and an accumulated deficit of approximately $371.4 million. These circumstances raise substantial doubt about our ability to continue to operate as a going concern for a period of one year after the issuance date of these consolidated financial statements.

At December 31, 2017, we had cash, cash equivalents and available for sale securities of approximately $0.4 million and restricted cash equivalents of $1.0 million. Additionally, we began shipments of our WiFi networking product line in October 2017. Although we anticipate growth in revenues and margin generated by this product line will reduce our net losses in 2018, sales of our WiFi product line will not be sufficient to fund our operations without the need for additional working capital. In addition, although we may receive proceeds from our patent enforcement actions in 2018, the timing and amount of such proceeds, if any, are difficult to predict and there can be no assurance we will receive any proceeds from these enforcement actions.

Our ability to meet our liquidity needs for the twelve months after the issuance date is dependent upon one or more of (i) our ability to develop, market and sell existing and new products; (ii) our ability to successfully negotiate licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment obligations to BKI and legal counsel; and/or (iii) our ability to raise additional capital from the sale of equity securities or other financing arrangements. We anticipate that we will continue to invest in patent protection, research and development, and production, selling and marketing of our WiFi networking product line. We expect that revenue generated from product sales, patent enforcement actions, and technology licenses over the twelve months after the issuance date will not be sufficient to cover our operating expenses. In the event we do not generate revenues, or other patent-asset proceeds, sufficient to cover our operational costs and contingent repayment obligation, we will be required to raise additional working capital through the sale of equity securities or other financing arrangements.

We are pursuing a two to three year financing transaction with third parties that may include debt, equity, in the form of common and preferred stock, or a combination thereof. There can be no assurance that we will be able to consummate a financing transaction with any of these third parties or that the terms of any such financing will be on terms and conditions that are acceptable. Until such time that we are able to consummate a longer-term financing transaction, we will continue to use the capacity available under our ATM and our common stock purchase agreement with Aspire to fund our short-term operations. The capital available to us under those financing vehicles is limited based on the remaining amounts available under our Shelf and limitations under Nasdaq rules with regards to the issuance of shares in excess of 19.99% of pre-transaction shares outstanding (see Note 11).

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. The consolidated financial statements include the accounts of ParkerVision, Inc. and our wholly-owned German subsidiary, ParkerVision GmbH after elimination of all intercompany transactions and accounts.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The more significant estimates made by us include projected future cash flows and risk-adjusted discount rates for estimating the fair value of our secured contingent payment obligation, the volatility and estimated lives of share-based awards used in the estimate of the fair market value of share-based compensation, the assessment of recoverability of long-lived assets, the amortization periods for intangible and long-lived assets, and the valuation allowance for deferred taxes. Actual results could differ from the estimates made. We periodically evaluate estimates used in the preparation of the financial statements for continued reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation.

Cash, Cash Equivalents, and Restricted Cash Equivalents

We consider cash and cash equivalents to include cash on hand, interest-bearing deposits, overnight repurchase agreements and investments with original maturities of three months or less when purchased. Restricted cash equivalents represent money market investments that are restricted for specific use in payment of legal fees and expenses related to certain of our patent infringement actions. The restricted money market investments have weighted average maturities of three months or less when purchased and are recorded at fair value. We have determined that the fair value of our restricted money market investments fall within Level 1 in the fair value hierarchy (see Note 16).

Available-for-Sale Securities

A vailable-for-sale securities are intended to be held for indefinite periods of time and are not intended to be held to maturity. These securities are recorded at fair value and any unrealized holding gains and losses, net of the related tax effect, are excluded from earnings and are reported as a separate component of accumulated other comprehensive loss until realized. The tax effect of our unrealized holding gains and losses is zero for each of the years ended December 31, 2017 and 2016 due to the existence of a full valuation allowance. Our available-for-sale securities at December 31, 2017 and 2016 consisted of mutual funds that invest primarily in short-term municipal securities with an average effective maturity of one year or less. All dividends and realized gains are recognized as other income as earned and immediately reinvested. The Company has determined that the fair value of its available-for-sale securities fall within Level 1 in the fair value hierarchy (See Note 16).

Inventory

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation. Depreciation is determined using the straight-line method over the following estimated useful lives:



Manufacturing and office equipment	5-7 years
Tooling	3 years
Leasehold improvements	Remaining life of lease
Furniture and fixtures	7 years
Computer equipment and software	3-5 years

The cost and accumulated depreciation of assets sold or retired are removed from their respective accounts, and any resulting net gain or loss is recognized in the accompanying consolidated statements of comprehensive loss. The carrying value of long-lived assets is reviewed on a regular basis for the existence of facts, both internally and externally, that may suggest impairment. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the assets exceeds its estimated undiscounted future net cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the assets.

Intangible Assets

Secured Contingent Payment Obligation

We have accounted for our secured contingent repayment obligation as long-term debt in accordance with Accounting Standards Codification (“ASC”) 470-10-25, “Sales of Future Revenues or Various other Measures of Income.” Our repayment obligations are contingent upon the receipt of proceeds from patent enforcement and/or patent monetization actions. We have elected to measure our secured contingent payment obligation at its fair value in accordance with ASC 825, “Financial Instruments” based on the variable and contingent nature of the repayment provisions. We have determined that the fair value of our secured contingent payment obligation falls within Level 3 in the fair value hierarchy which involves significant estimates and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows (see Note 16). Actual results could differ from the estimates made. Changes in fair value, including the component related to imputed interest, are included in the accompanying consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligation”.

Leases

Our facilities are leased under operating leases. For those leases that contain rent escalations or rent concessions, we record the total rent payable during the lease term on a straight-line basis over the term of the lease with the difference between the rents paid and the straight-line rent recorded as a deferred rent liability in the accompanying consolidated balance sheets.

In February 2016, the FASB issued ASU 2016-02 “Leases,” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and operating leases with lease terms of more than 12 months. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. Upon adoption of ASU 2016-02, beginning period balances for the earliest period presented must be adjusted to reflect the re-measurement of lease assets and liabilities. We anticipate adoption of ASU 2016-02 as of January 1, 2019. We have identified all existing operating and financing leases and are in the process of determining the present value of existing lease assets and liabilities under the new guidance. We are also currently formalizing processes and controls to identify, classify and measure new leases in accordance with ASU 2016-02. The impact of ASU 2016-02 on our consolidated financial statements is currently being evaluated.

Revenue Recognition

We derive revenue from licensing of our intellectual property, settlements from patent infringement disputes, sales of products, and engineering services. The timing of revenue recognition and the amount of revenue recognized depends upon a variety of factors, including the specific terms of each arrangement and the nature of our deliverables and obligations. In general, we recognize revenue when there is persuasive evidence of an arrangement, title has transferred, the amounts are fixed and determinable and the collectability is reasonably assured.

Revenue from the sale of products is recognized at the time of shipment to the customer or when the other criteria for revenue recognition are met, if later. Unearned revenue at December 31, 2017 and 2016 consists of product inventory held by a distributor. Revenue from the sale of our products includes shipping and handling charged to the customer. Product revenue is recorded net of sales tax collected from customers, discounts, and actual and estimated future returns.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. ASU 2015-14, “Revenue from Contracts with Customers (Topic 606)”, issued in August 2015, defers adoption of ASU 2014-09 to annual reporting periods beginning after December 15, 2017. We do not currently expect the adoption of ASU 2014-09 to have a material effect on our consolidated financial statements .

Shipping and Handling Costs

Shipping and handling costs related to product sales were approximately $5,000 , or 5% of product revenue, for the year ended December 31, 2017. These costs are included in selling, general and administrative expenses in the accompanying consolidated statements of comprehensive loss.

Advertising Expense

Advertising costs are expensed as incurred. Advertising expenses of approximately $0.4 million and $0 for the years ended December 31, 2017 and 2016, respectively, are included in selling, general, and administrative expenses in the accompanying consolidated statements of comprehensive loss.

Research and Development Expenses

Research and development costs are expensed as incurred and include salaries and benefits, costs paid to third party contractors, prototype expenses, an allocated portion of facilities costs, maintenance costs for software development tools, and depreciation.

Accounting for Share-Based Compensation

We have various share-based compensation programs which provide for equity awards including stock options, restricted stock units (“RSUs”) and restricted stock awards (“RSAs”). We calculate the fair value of employee share-based equity awards on the date of grant and recognize the calculated fair value as compensation expense over the requisite service periods of the related awards. We estimate the fair value of stock option awards using the Black-Scholes option valuation model. This valuation model requires the use of highly subjective assumptions and estimates including how long employees will retain their stock options before exercising them and the volatility of our common stock price over the expected life of the equity award. Such estimates, and the basis for our conclusions regarding such estimates, are outlined in detail in Note 10. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. We account for forfeitures of share-based awards as they occur.

In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” This update provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. The new standard is effective for annual periods beginning after December 15, 2017 and interim periods within those years. Early adoption is permitted. The adoption of this guidance is not expected to have a material effect on our consolidated financial statements.

Income Taxes

The provision for income taxes is based on loss before taxes as reported in the accompanying consolidated statements of comprehensive loss. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized. Our deferred tax assets exclude unrecognized tax benefits which do not meet a more-likely-than-not threshold for financial statement recognition for tax positions taken or expected to be taken in a tax return.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease to 21% effective for tax years beginning after December 31, 2017.

Loss per Common Share

Basic loss per common share is determined based on the weighted-average number of common shares outstanding during each year. Diluted loss per common share is the same as basic loss per common share as all potential common shares are excluded from the calculation, as their effect is anti-dilutive.

Options and warrants to purchase 1.4 million and 1.1 million shares of common stock were outstanding at December 31, 2017 and, 2016, respectively. In addition, unvested RSUs representing 0.5 million and 0.3 million shares of common stock were outstanding at December 31, 2017 and 2016, respectively. These options, warrants and RSUs were excluded from the computation of diluted loss per share as their effect would have been anti-dilutive.

Depreciation expense related to property and equipment was approximately $0.15 million and $0.17 million in 2017 and 2016, respectively. Depreciation expense includes depreciation related to capital leases of approximately $0.05 million and $0.06 for the periods ended December 31, 2017 and 2016, respectively.

Our capital leases have original terms of one to three years. The principal payments for these capital leases are reflected as cash outflows from financing activities in the accompanying consolidated statements of cash flows. Future minimum lease payments under our capital leases that have initial terms in excess of one year are included in “Contractual Obligations” in Note 13.

The note payable to a related party at December 31, 2017 and 2016, consisted of the following (in thousands):




Description	Interest Rate	Interest Payable	Maturity Date	2017		2016
Note payable to a related party	8%	Monthly	March 31, 2020	$	825	$	825
Less current maturities					294		825
Long-term note payable				$	531	$	-

In February 2016, we entered into an agreement with a related party (see Note 14) to convert $0.8 million in outstanding unpaid fees into an unsecured promissory note. The balance of the note was scheduled to mature on December 31, 2017. In January 2018, we amended the note, retroactive to December 31, 2017 to allow for interest only payments through March 2018 and principle and interest payments through March 31, 2020.

Failure to comply with the payment terms of this note constitutes an event of default which, if uncured, will result in the entire unpaid principal balance of the note and any unpaid, accrued interest to become immediately due and payable. As of December 31, 2017, we are in compliance with the payment terms of the note.

At December 31, 2017, the aggregate maturities of our note payable to a related party are as follows (in thousands):



2018	$	294
2019		420
2020		111
Total	$	825

The estimated fair value of our note payable at December 31, 2017 is approximately $0.7 million based on a risk-adjusted discount rate.

Secured Contingent Payment Obligation

The following table provides a reconciliation of our secured contingent payment obligation measured at estimated fair market value for the year ended December 31, 2017 and 2016, respectively (in thousands).




		2017		2016
Secured contingent payment obligation, beginning of year	$	14,185	$	-
Proceeds from contingent payment obligation 1		1,000		12,665
Repayment		-		(3,340)
Change in fair value		711		4,860
Secured contingent payment obligation, end of year	$	15,896	$	14,185

Proceeds in 2016 are net of $0.3 million which represents the estimated fair market value of warrants issued in connection with the agreement (see Note 11).

Our secured contingent payment obligation represents the estimated fair value of our repayment obligation to Brickell Key Investments (“BKI”) under a February 2016 funding agreement, as amended in May 2016 and December 2017. Under the agreement, we received aggregate proceeds of $14 million in exchange for BKI’s right to reimbursement and compensation from gross proceeds resulting from patent enforcement and other patent monetization actions.

BKI is entitled to priority payment of 100% of proceeds received from all patent-related actions until such time that BKI has been repaid in full. After repayment of the funded amount, BKI is entitled to a portion of remaining proceeds up to a specified minimum return which is determined as a percentage of the funded amount and varies based on the timing of repayment. In addition, BKI is entitled to a pro rata portion of proceeds from specified legal actions to the extent aggregate proceeds from those actions exceed the specified minimum return.

BKI holds a senior security interest in our assets until such time as the specified minimum return is paid, in which case, the security interest will be released except with respect to the patents and proceeds related to specific legal actions. The security interest is enforceable by BKI in the event that we are in default under the agreement which would occur if (i) we fail, after notice, to pay proceeds to BKI, (ii) we become insolvent or insolvency proceedings are commenced (and not subsequently discharged) with respect to us, (iii) our creditors commence actions against us (which are not subsequently discharged) that affect our material assets, (iv) we, without BKI’s consent, incur indebtedness other than immaterial ordinary course indebtedness, or (v) there is an uncured non-compliance of our obligations or misrepresentations under the agreement. As of December 31, 2017, we are in compliance with our obligations under this agreement.

We have elected to measure our secured contingent payment obligation at fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods (see Note 16). The secured contingent payment obligation is remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved.

9. INCOME TAXES AND TAX STATUS

Our net losses before income taxes for the years ended December 31, 2017 and 2016 are from domestic operations as well as losses from our wholly-owned German subsidiary. We elected to treat our German subsidiary as a disregarded entity for purposes of income taxes and accordingly, the losses from our German subsidiary has been included in our operating results.

We recorded $0.7 million in current foreign income tax expense for the year ended December 31, 2016 as a result of foreign tax withholding on licensing revenues from a Korean entity. No current or deferred tax provision or benefit was recorded for 2017 and 2016 as a result of current losses and fully deferred tax valuation allowances for all periods. We have recorded a valuation allowance to state our deferred tax assets at their estimated net realizable value due to the uncertainty related to realization of these assets through future taxable income.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation, the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code that includes a reduction to the U.S. federal corporate statutory tax rate to 21% effective in 2018. As of December 31, 2017, our accounting for the income tax effects of the Tax Act has been completed. The federal corporate tax rate reduction creates a reduction to our deferred tax assets and liabilities with a corresponding reduction to our valuation allowance.

A reconciliation between the provision for income taxes and the expected tax benefit using the federal statutory rate of 34 % for the years ended December 31, 2017 and 2016 are as follows (in thousands):



	2017		2016

Our deferred tax assets and liabilities relate to the following sources and differences between financial accounting and the tax bases of our assets and liabilities at December 31, 2017 and 2016 (in thousands):



	2017		2016
Gross deferred tax assets:

At December 31, 2017, we had cumulative NOL, research and development (“R&D”) tax credit carry-forwards and ca pital loss carry-forwards for income tax purposes of $328.4 million, $8.1 million and $0.01 million, respectively , which expire in varying amounts from 2018 through 2036 .

Our ability to benefit from the our tax credit carry-forwards could be limited under certain provisions of the Internal Revenue Code if our ownership changes by more than 50%, as defined by Section 382 of the Internal Revenue Code of 1986 (“Section 382”). Under Section 382, an ownership change may limit the amount of NOL, capital loss and R&D credit carry-forwards that can be used annually to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. We conduct a study annually of our ownership changes. Based on the results of our studies, we have determined that we do not have any ownership changes on or prior to December 31, 2017 which would result in limitations of our NOL, capital loss or R&D credit carry-forwards under Section 382.

Uncertain Tax Positions

We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. We have identified our Federal and Florida tax returns as our only major jurisdictions, as defined. The periods subject to examination for those returns are the 1998 through 2017 tax years. The following table provides a reconciliation of our unrecognized tax benefits due to uncertain tax positions for the years ended December 31, 2017 and 2016, respectively (in thousands).



	2017		2016
Unrecognized tax benefits – beginning of year	$	1,370	$	1,370
Gross increases – tax positions in prior period		-		-
Impact of the Tax Act		(443)		-
Unrecognized tax benefits – end of year	$	927	$	1,370

Future changes in the unrecognized tax benefit will have no impact on the effective tax rate so long as we maintain a full valuation allowance.

Our policy is that we recognize interest and penalties accrued on any unrecognized tax benefits as a component of our income tax expense. We do not have any accrued interest or penalties associated with any unrecognized tax benefits. For the years ended December 31, 2017 and 2016, we did not incur any income tax-related interest income, expense or penalties.

10. SHARE-BASED COMPENSATION

The following table presents share-based compensation expense included in our consolidated statements of comprehensive loss for the years ended December 31, 2017 and 2016, respectively (in thousands):



	2017		2016
Research and development expense	$	564	$	630
Selling, general, and administrative expense		1,600		1,580
Total share-based compensation expense	$	2,164	$	2,210

We did not capitalize any expense related to share-based payments. As of December 31, 2017, there was $1.2 million of total unrecognized compensation cost related to all non-vested share-based compensation awards. That cost is expected to be recognized over a weighted-average period of approximately one year.

Stock Incentive Plans

2011 Long-Term Incentive Equity Plan

We adopted a long-term incentive equity plan in September 2011 that, as amended in 2014, 2016 and 2017, provided for the grant of stock-based awards to employees, officers, directors and consultants, not to exceed 3.0 million shares of common stock (the “2011 Plan”). The 2011 Plan provides for benefits in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted share awards, and other stock based awards. Forfeited and expired options under the 2011 Plan become available for reissuance. The plan provides that no participant may be granted awards in excess of 150,000 shares in any calendar year. At December 31, 2017, approximately 673,896 shares of common stock were available for future grants under the 2011 Plan.

2008 Equity Incentive Plan

We adopted an equity incentive plan in August 2008 (the “2008 Plan”). The 2008 Plan provides for the grant of stock-based awards to employees (excluding named executives), directors and consultants, not to exceed 50,000 shares of common stock. The 2008 Plan provides for benefits in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted share awards, and other stock based awards. Forfeited and expired options under the 2008 Plan become available for reissuance. The plan provides that no participant may be granted awards in excess of 5,000 shares in any calendar year. At December 31, 2017, 15,142 shares of common stock were available for future grants under the 2008 Plan.

2000 Performance Equity Plan

We adopted a performance equity plan in July 2000 (the “2000 Plan”). The 2000 Plan provided for the grant of options and other stock awards to employees, directors and consultants, not to exceed 500,000 shares of common stock. The 2000 Plan provided for benefits in the form of incentive and nonqualified stock options, stock appreciation rights, restricted share awards, stock bonuses and various stock benefits or cash. Upon shareholder approval of amendments to our 2011 Long-Term Incentive Equity Plan on June 17, 2014, the 2000 Plan was amended such that no further awards may be granted under this plan.

Restricted Stock Awards

RSAs are issued as executive and employee incentive compensation and as payment for services to others. The value of the award is based on the closing price of our common stock on the date of grant. RSAs are generally immediately vested.

Restricted Stock Units

RSUs are issued as incentive compensation to executives, employees, and non-employee directors as well as payment for services to third parties. Each RSU represents a right to one share of our common stock, upon vesting. The RSUs are not entitled to voting rights or dividends, if any, until vested. RSUs generally vest over a one to three year period for employee awards, a one year period for non-employee director awards and the life of the related service contract for third-party awards. The fair value of RSUs is generally based on the closing price of our common stock on the date of grant and is amortized to share-based compensation expense over the estimated life of the award, generally the vesting period. In the case of RSUs issued to third parties, the fair value is recognized based on the closing price of our common stock on each vesting date.

RSAs and RSUs

The following table presents a summary of RSA and RSU activity under the 2000, 2008, and 2011 Plans (collectively, the “Stock Plans”) as of December 31, 2017 (shares in thousands):



	Non-vested Shares
	Shares	Weighted-Average Grant-Date Fair Value
Non-vested at beginning of year	330	$	5.16
Granted	669		1.98
Vested	(476)		4.18
Forfeited	(2)		1.98
Non-vested at end of year	521	$	1.98

The total fair value of RSAs and RSUs vested under the Stock Plans for the year ended December 31, 2017 is $0.9 million.

Stock Options

Stock options are issued as incentive compensation to executives, employees, non-employee directors, and third parties. Stock options are generally granted with exercise prices at or above fair market value of the underlying shares at the date of grant. The fair value of options granted is estimated using the Black-Scholes option pricing model. Generally, fair value is determined as of the grant date. In the case of option grants to third parties, the fair value is estimated at each interim reporting date until vested. Options for employees, including executives and non-employee directors, are generally granted under the Stock Plans.

The following table presents a summary of option activity under the Stock Plans for the year ended December 31, 2017 (shares in thousands):



	Shares	Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term		Aggregate Intrinsic Value ($)
Outstanding at beginning of year	691	$	14.89
Granted	318		1.97
Exercised	-		-
Forfeited	-		-
Expired	(2)		6.80
Outstanding at end of year	1,007		10.82	3.68	years	$	-
Vested and expected to vest at end of year	671	$	15.26	2.33	years	$	-

The weighted average per share fair value of option shares granted during the years ended December 31, 2017 and 2016 was $1.52 and $1.74 , respectively. The total fair value of option shares vested was $0.2 million for each of the years ended December 31, 2017 and 2016.

The fair value of option grants under the Stock Plans for the years ended December 31, 2017 and 2016, respectively, was estimated using the Black-Scholes option-pricing model with the following assumptions:



	Year ended December 31,
	2017	2016
Expected option term 1	4 to 6 years	7 years
Expected volatility factor 2	98.0% to 100.8%	97.80%
Risk-free interest rate 3	1.7% to 2.2%	2.3%
Expected annual dividend yield	0%	0%

1 The expected term was generally determined based on historical activity for grants with similar terms and for similar groups of employees and represents the period of time that options are expected to be outstanding. For employee options, groups of employees with similar historical exercise behavior are considered separately for valuation purposes. For consultants, the expected term was determined based on the contractual life of the award.

2 The stock volatility for each grant is measured using the weighted average of historical daily price changes of our common stock over the most recent period equal to the expected option life of the grant.

3 The risk-free interest rate for periods equal to the expected term of the share option is based on the U.S. Treasury yield curve in effect at the measurement date.

We occasionally grant stock options outside the Stock Plans, generally to third parties. At December 31, 2016, we had one option for the purchase of 6,000 shares of common stock outstanding and exercisable at an exercise price of $20.10 . This option expired unexercised in October 2017. At December 31, 2017, there were no outstanding options outside the Stock Plans.

Options by Price Range

The options outstanding at December 31, 2017 under all plans have exercise price ranges, weighted average contractual lives, and weighted average exercise prices are as follows (weighted average lives in years and shares in thousands):



	Options Outstanding				Options Vested
Range of Exercise Prices	Number Outstanding at December 31, 2017	Wtd. Avg. Exercise Price		Wtd. Avg. Remaining Contractual Life	Number Exercisable at December 31, 2017	Wtd. Avg. Exercise Price		Wtd. Avg. Remaining Contractual Life
$1.11 - $1.80	66	$	1.75	5.06	30	$	1.80	4.88
$1.84 - $5.80	416		2.05	6.41	116		2.17	6.05
$7.50 - $11.80	227		8.98	0.77	227		8.98	0.77
$13.20 - $22.60	46		13.72	2.68	46		13.72	2.68
$23.80 - $38.80	243		28.25	1.58	243		28.25	1.58
$45.10 - $45.10	9		45.10	2.96	9		45.10	2.96
	1,007	$	10.82	3.68	671	$	15.26	2.33

Upon exercise of options under all plans, we issue new shares of our common stock. For shares issued upon exercise of equity awards granted under the Stock Plans, the shares of common stock are registered. For shares issued upon exercise of non-plan awards, the shares are not registered unless they have been subsequently registered by us on a registration statement. We have had no option exercises for the years ended December 31, 2017 and 2016.

11. STOCK AUTHORIZATION AND ISSUANCE

Preferred Stock

We have 15 million shares of preferred stock authorized for issuance at the direction of the board of directors. On November 17, 2005, our board of directors designated 0.1 million shares of authorized preferred stock as the Series E Preferred Stock in conjunction with its adoption of a Shareholder Protection Rights Agreement (Note 12). As of December 31, 2017, we had no outstanding preferred stock.

Common Stock

On July 11, 2017, our shareholders approved an amendment to our articles of incorporation to increase the number of authorized shares of common stock from 20 million to 30 million shares.

Stock Issuances

The following table presents a summary of completed equity offerings for the years ended December 31, 2017 and 2016 (in thousands, except for per share amounts):

Shares are registered under a registration statement that was declared effective August 2, 2016 (File No. 333-212670).

Common Stock Purchase Agreement

In October 2017, we entered into a common stock purchase agreement (the “Purchase Agreement”) with Aspire Capital Fund, LLC (“Aspire Capital”). Under the Purchase Agreement, Aspire Capital committed to purchase up to an aggregate of $20 million in shares of our common stock over the 30 -month term of the Purchase Agreement. In consideration for entering into the Purchase Agreement, we issued to Aspire Capital 287,500 shares of our common stock as a commitment fee. We filed a registration statement to register the sale of up to 4 million shares of our common stock by Aspire Capital that have been or may be issued under the Purchase Agreement. The registration statement was declared effective November 27, 2017 (File No. 333-221250).

Under the Purchase Agreement, on any trading day selected by us, we have the right, in our sole discretion, to present Aspire Capital with a purchase notice, directing Aspire Capital to purchase up to 150,000 shares of our common stock, provided that the aggregate purchase amount for such shares does not exceed $0.5 million and subject to the maximum aggregate amount of $20 million. The per share purchase price for each purchase notice is equal to the lesser of (i) the lowest sale price of our common stock on the purchase date; or (ii) the arithmetic average of the three lowest closing sale prices for our common stock during the ten consecutive trading days ending on the trading day immediately preceding the purchase date.

In addition, on any date on which we submit a purchase notice to Aspire Capital, we also have the right, in our sole discretion, to present Aspire Capital with a volume-weighted average price (“VWAP”) purchase notice directing Aspire Capital to purchase an amount of stock equal to up to 30% of the aggregate shares of our common stock traded on its principal market on the next trading day, or such lesser amount as we may determine. The purchase price per share pursuant to the VWAP purchase notice is generally 97% of the volume-weighted average price for our common stock traded on its principal market on the VWAP purchase date, subject to terms and limitations of the agreement.

The number of shares that may be issued to Aspire Capital under the Purchase Agreement is limited to that number of shares representing 19.99% of our pre-transaction shares outstanding (the “Exchange Cap”), unless shareholder approval is obtained or unless the average price for shares sold in excess of the Exchange Cap is equal or greater to $1.48 which represents the closing bid price of our common stock at the date we entered into the Purchase Agreement.

At Market Issuance Sales Agreements

We filed a shelf registration statement on Form S-3 with the SEC in November 2016 (Registration No. 333-214598) for the offering of various securities, up to $15 million, over a period of up to three years. On December 30, 2016, we entered into an ATM agreement with FBR Capital Markets & Co. (“FBR”) for the sale of up to $10 million in shares of our common stock under the shelf registration statement (the “First ATM”). From January through March 2017, we sold an aggregate of 4.1 million shares of our common stock at an average price of $2.46 per share under the First ATM.

On August 14, 2017, we entered into a new ATM agreement with FBR for the sale of up to approximately $4.4 million in shares of our common stock registered under the shelf registration statement (the “Second ATM”). From August to December 2017, we completed the sale of approximately 2.1 million shares of our common stock at an average price of $1.50 under the Second ATM. We had approximately $1.2 million remaining available for sale under the Second ATM as of December 31, 2017.

Stock for Services

For the year ended December 31, 2017, we issued an aggregate of 0.3 million shares of unregistered common stock to two consultants in exchange for an aggregate of approximately $0.4 million in prepaid retainers for executive consulting and other advisory services. We have no registration obligation with respect to these shares.

Common Stock Warrants

As of December 31, 2017, we had outstanding warrants for the purchase of up to 0.4 million shares of our common stock. The estimated grant date fair value of these warrants of $0.8 million is included in shareholders’ (deficit) equity in our consolidated balance sheets. The outstanding warrants have an average exercise price of $2.21 per share and a weighted average remaining life of approximately three years. Cash received from warrant exercises for the years ended December 31, 2017 and 2016 was $0 and $0.4 million, respectively.

Our outstanding warrants include a warrant issued to BKI in connection with our secured contingent payable obligation (see Note 8). The BKI warrant is for the purchase up to 350,000 shares of our common stock at an exercise price of $2.00 per share valued at its estimated fair market value of $0.3 million using a discounted Black-Scholes model. The aggregate fair value of the BKI warrant is included in shareholders’ (deficit) equity in the consolidated balance sheets at December 31, 2017 and 2016. The shares underlying the warrants were registered on a registration statement declared effective on August 2, 2016.

Director Stock Purchase

On March 26, 2018 three of our directors purchased an aggregate of 0.2 million shares of our common stock in an unregistered sale of equity securities at a purchase price of $0.83 per share. We received proceeds of approximately $0.2 million.

12. SHAREHOLDER PROTECTION RIGHTS AGREEMENT

On November 20, 2015, we amended our Shareholder Protection Rights Agreement (“Rights Agreement”) dated November 21, 2005. The amendment extends the expiration date of the Rights Agreement from November 21, 2015 to November 20, 2020 and decreases the exercise price of the rights to $14.50 after giving effect to the one -for-ten reverse stock split that became effective March 30, 2016.

The Rights Agreement provided for the issuance, on November 29, 2005, as a dividend, rights to acquire fractional shares of Series E Preferred Stock. We did not assign any value to the dividend as the value of these rights is not believed to be objectively determinable. The principal objective of the Rights Agreement is to cause someone interested in acquiring us to negotiate with our board of directors (the “Board”) rather than launch an unsolicited or hostile bid. The Rights Agreement subjects a potential acquirer to substantial voting and economic dilution. Each share of common stock issued by ParkerVision will include an attached right.

The rights initially are not exercisable and trade with the common stock of ParkerVision. In the future, the rights may become exchangeable for shares of Series E Preferred Stock with various provisions that may discourage a takeover bid. Additionally, the rights have what are known as “flip-in” and “flip-over” provisions that could make any acquisition of us more costly to the potential acquirer. The rights may separate from the common stock following the acquisition of 15 % or more of the outstanding shares of common stock by an acquiring person. Upon separation, the holder of the rights may exercise their right at an exercise price of $ 14.50 per right (the “Exercise Price”), subject to adjustment and payable in cash. Upon payment of the Exercise Price, the holder of the right will receive from us that number of shares of common stock having an aggregate market price equal to twice the Exercise Price, as adjusted. The Rights Agreement also has a flip over provision allowing the holder to purchase that number of shares of common/voting equity of a successor entity, if we are not the surviving corporation in a business combination, at an aggregate market price equal to twice the Exercise Price. We have the right to substitute for any of our shares of common stock that we are obligated to issue, shares of Series E Preferred Stock at a ratio of one ten-thousandth of a share of Series E Preferred Stock for each share of common stock. The Series E Preferred Stock, if and when issued, will have quarterly cumulative dividend rights payable when and as declared by the Board, liquidation, dissolution and winding up preferences, voting rights and will rank junior to other securities of ParkerVision unless otherwise determined by the Board.

The rights may be redeemed upon approval of the Board at a redemption price of $ 0.01 .

13. COMMITMENTS AND CONTINGENCIES

Lease Commitments

The following table presents a summary of our facilities under non-cancelable lease agreements at December 31, 2017:



Description	Lease Start Date	Lease End Date	Renewal options remaining	Straight line monthly rental payment (in thousands)
Corporate office, Jacksonville, Florida	6/1/2006	7/15/2018	none	$	28

Wireless design facility, Lake Mary, Florida	7/1/2017	11/30/2022	2 options to extend for 36 months each	$	13

Warehouse and production facility, Jacksonville, Florida	7/1/2017	7/31/2020	none	$	2

Deferred rent is amortized to rent expense over the respective lease terms. In addition to sales tax payable on base rental amounts, certain leases obligate us to pay pro-rated annual operating expenses for the properties. Rent expense for properties, for the years ended December 31, 2017 and 2016 was $0.6 million and $0.5 million, respectively.

Contractual Obligations

Future minimum lease payments under all non-cancelable operating leases and capital leases that have initial terms in excess of one year as of December 31, 2017 were as follows (in thousands):



Contractual obligations:	2018		2019		2020 and thereafter		Total
Operating leases	$	372	$	185	$	535	$	1,092
Capital leases	$	2	$	2	$	1	$	5

Legal Proceedings

From time to time, we are subject to legal proceedings and claims which arise in the ordinary course of our business. These proceedings include patent enforcement actions initiated by us against others for the infringement of our technologies, as well as proceedings brought by others against us at the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office (“PTAB”) and in the Federal Patent Court in Germany in an attempt to invalidate certain of our patent claims. These patent-related proceedings are more fully described below. We have several patent enforcement actions in Germany which has a “loser pay” system whereby the non-prevailing party is responsible for statutory attorney fees and costs. We do not believe it is probable that we will have unfavorable outcomes in any of our German cases and therefore we have not recorded any expenses related to these statutory fees and costs. However, there is at least a reasonable possibility of an unfavorable outcome in any one or more of these matters that could result in expenses in the aggregate that could have a material unfavorable impact on our results of operations as more fully discussed below.

ParkerVision v. Qualcomm and HTC (Middle District of Florida)

We have a patent infringement complaint pending in the Middle District of Florida against Qualcomm and Qualcomm Atheros, Inc. (collectively “Qualcomm”), and HTC (HTC Corporation and HTC America, Inc.) (the “Qualcomm Action”) seeking unspecified damages and injunctive relief for infringement of certain of our patents. Certain of the defendants have filed counterclaims against us for non-infringement and invalidity for all patents in the case. A claim construction hearing was held in August 2015 but no ruling on claim construction has been issued by the court. In February 2016, the court granted the parties’ joint motion to stay these proceedings until resolution of the proceedings at the International Trade Commission (“ITC”) as discussed below. In May 2017, we filed a motion to continue the stay of these proceedings pending an appeal of certain PTAB decisions with regard to our U.S. Patent 6,091,940 (“the ‘940 Patent”) as discussed below.

Qualcomm v. ParkerVision (PTAB)

In August 2015, Qualcomm filed an aggregate of ten petitions for Inter Partes Review (“IPR”) with the PTAB seeking to invalidate certain claims related to three of the eleven patents originally asserted in our Qualcomm Action. In March 2016, the PTAB issued decisions denying institution of trial for three of the petitions, all of which relate to our U.S. patent 7,039,372 (“the ‘372 Patent”). The remaining petitions, all of which relate to the ‘940 Patent and U.S. patent 7,966,012 (“the ‘012 Patent”) were instituted for trial by the PTAB. In May 2016, the PTAB granted our motion to disclaim the challenged claims of the ‘012 Patent and entered an adverse judgment against us with respect to those claims. In March 2017, the PTAB issued its decisions on the six outstanding IPRs, all of which relate to the ‘940 Patent. The PTAB ruled in our favor on three of the six petitions, ruled in Qualcomm’s favor on two of the six petitions and issued a split decision on the claims covered in the sixth petition. As a result of the PTAB decisions, certain claims of the ‘940 Patent which are the subject of our district court case against Qualcomm and HTC were found to be un-patentable. In May 2017, we filed our notice of appeal of these decisions with the Federal Circuit. Qualcomm also cross- appealed . Briefing is complete and we expect oral arguments to be scheduled in the second or third quarter of 2018.

ParkerVision v. Apple and Qualcomm (ITC)

In December 2015, we filed a complaint with the U.S. ITC against Apple, Inc., LG Electronics, Inc., LG Electronics U.S.A., Inc., and LG Electronics MobileComm U.S.A., Inc. (collectively “LG”), Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., and Samsung Semiconductor, Inc. (collectively “Samsung”) and Qualcomm alleging that these companies make, use or sell products that infringe certain of our patent claims and requesting that the ITC bar the defendants from continuing to import and sell infringing products in the U.S. We filed a corresponding patent infringement complaint in the Middle District of Florida against these same defendants. In January 2016, the ITC instituted an investigation based on our complaint. In July 2016, we entered into a confidential patent license and settlement agreement with Samsung and, as a result, Samsung was removed from the ITC action. In January 2017, we dismissed three of the four patents from the case in order to simplify the investigation. On March 10, 2017, the administrative law judge issued a ruling on a pre-trial motion that precluded us from presenting key evidence in our case. As a result, on March 13, 2017, we filed a motion to terminate the proceedings at the ITC. On April 28, 2017, the ITC granted our motion to withdraw from the ITC proceedings.

ParkerVision v. Apple and Qualcomm (Middle District of Florida)

In connection with our complaint filed at the ITC in December 2015 as discussed above, we filed a corresponding patent infringement complaint in the Middle District of Florida against Apple, LG, Samsung and Qualcomm alleging infringement of four of our patents. In February 2016, the district court proceedings were stayed pending resolution of the proceedings at the ITC and in July 2016, Samsung was removed from the district court action as a result of a patent license and settlement agreement. Following the termination of the ITC proceedings in March 2017, we filed a motion to lift the stay in the district court case. This motion was granted in May 2017. In July 2017, we filed a motion to dismiss LG from

the district court case (see ParkerVision v. LG below). Also in July 2017, Qualcomm filed a motion to change venue to the southern district of California and Apple filed a motion to dismiss for improper venue. In March 2018, the district court ruled against the Qualcomm and Apple motions. The parties also filed a joint motion in March 2018 to eliminate three of the four patents in the case in order to expedite proceedings. The parties are awaiting a revised court schedule for the proceedings, including the claim construction hearing which was originally scheduled for January 2018.

ParkerVision v. LG (District of New Jersey)

In July 2017, we filed a patent infringement complaint in the district of New Jersey against LG for the alleged infringement of the same patents previously asserted against LG in the middle district of Florida (see ParkerVision v. Apple and Qualcomm above). We elected to dismiss the case in the middle district of Florida and re-file in New Jersey as a result of a recent Supreme Court ruling regarding proper venue. In March 2018, the court stayed this case pending a final decision in ParkerVision v. Apple and Qualcomm in the Middle District of Florida. As part of this stay, LG has agreed to be bound by the final claim construction decision in that case.

ParkerVision v. LG Electronics (Munich, Germany)

In June 2016, we filed a complaint in Munich District Court against LG Electronics Deutschland GmbH, a German subsidiary of LG Electronics, Inc. (“LGE”) seeking damages and injunctive relief for the alleged infringement of the German part of our European patent 1 206 831 (“the ‘831 Patent). A hearing in this case was held in November 2016 at which time the court concluded that certain LGE products using Qualcomm RF circuitry infringe our patent. The final decision in this case is stayed pending resolution of the corresponding nullity, or validity, action filed by Qualcomm in the German Federal Patent Court in Munich (see Qualcomm v. ParkerVision below). If we do not prevail in this case, we may be subject to a claim for reimbursement of statutory attorney’s fees and costs estimated at approximately $0.06 million for which we have posted a bond. If we prevail in the validity action filed by Qualcomm, the district court will then issue its final infringement decision which, if favorable, will likely include an injunction blocking the sale and importation of LGE products in Germany.

ParkerVision v. Apple (Munich, Germany)

In October 2016, we filed a complaint in Munich District Court against Apple, Inc., Apple Distribution International, and Apple Retail Germany B.V. & Co. KG (collectively “Apple”) seeking damages and injunctive relief for the alleged infringement of the ‘831 Patent (the “Apple I” case). In February 2017, we amended our complaint adding the infringement of a second German patent and alleging infringement by Apple devices that incorporate an Intel transceiver chip. The Munich Regional Court bifurcated the new claims into a second case (the “Apple II” case). A hearing was held in May 2017 in the Apple I case. In June 2017, the court deferred its ruling pending the decision from the German Federal Patent Court in the validity action filed by Qualcomm (see Qualcomm v. ParkerVision below ). We anticipate the decision in this case will mirror that in the ParkerVision v. LG case in Germany discussed above. If we do not prevail in this case, we may be subject to a claim for reimbursement of statutory attorney’s fees and costs estimated at approximately $0.1 million. We expect that we will post a bond to cover this exposure in 2018.

Qualcomm v. ParkerVision (Federal Patent Court in Germany)

In August 2016, Qualcomm filed a validity action in Federal Patent Court in Germany against the ’831 Patent. The outcome of this validity action impacts our German patent infringement cases against LGE and Apple as discussed above. An oral hearing is scheduled in this case on October 17, 2018 and a decision is expected to be handed down at that time. The Federal Patent Court can uphold the ‘831 Patent, declare the ‘831 Patent to be invalid, or, alternatively, can uphold the ‘831 Patent with amended, narrowed claims that we have proposed. If the ‘831 Patent is declared invalid, we would be subject to a claim for reimbursement of statutory attorney fees and costs of approximately $0.2 million.

ParkerVision v. Apple (Munich, Germany)- the Apple II case

The Apple II case seeks damages and injunctive relief for the alleged infringement of the German part of our European patent 1 135 853 (“the ‘853 Patent). A hearing was held in November 2017. Subsequent to the hearing, the court requested that we supplement certain elements of the infringement claims against Apple devices. The court also denied Apple’s request that we provide a bond covering any possible claims for reimbursement of statutory attorney’s fees and costs; however, in order to expedite proceedings, we have agreed to pay a bond of approximately $0.1 million in April 2018, which is our estimated maximum exposure in this case. We expect a second oral hearing in this case to take place in the second quarter of 2018.

Intel v. ParkerVision (Federal Patent Court in Germany)

In August 2017, Intel filed a nullity action in German Federal Patent Court claiming invalidity of the ‘853 Patent that is the subject of the Apple II case. If the ‘853 Patent is declared invalid, we would be subject to a claim for reimbursement of statutory attorney fees and costs of approximately $0.2 million. We intend to vigorously defend the validity of our patent. No dates have yet been set in this nullity action.

14. RELATED PARTY TRANSACTIONS

We paid approximately $0.03 million and $0.4 million in 2017 and 2016, respectively, for patent-related legal services to the law firm of Sterne, Kessler, Goldstein & Fox, PLLC (“SKGF”), of which Robert Sterne, one of our directors since September 2006, is a partner. In February 2016, we entered into an agreement with SKGF to convert $0.8 million in outstanding unpaid fees to an unsecured note payable. In December 2017, we entered into a note modification agreement with SKGF to extend the maturity date of the note from December 31, 2017 to March 31, 2020 (see Note 8). We paid SKGF interest on the note payable of approximately $0.07 million a nd $0.06 million in 2017 and 2016, respectively.

In February 2017, Mr. Paul Rosenbaum, one of our directors since December 2016, purchased 80,510 shares of our common stock in an unregistered sale of equity securities at a purchase price of $2.11 per share (see Note 11).

15. CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject us to a concentration of credit risk principally consist of cash and cash equivalents, restricted cash equivalents, and our available for sale securities. Cash and cash equivalents are primarily held in bank accounts and overnight investments. At times our cash balances on deposit with banks may exceed the balance insured by the F.D.I.C. Restricted cash equivalents are held in accounts with brokerage institutions and consist of short-term money market funds. Our available-for-sale securities are held in accounts with brokerage institutions and consist of mutual funds invested primarily in short-term municipal securities.

We maintain our investments with what management believes to be quality financial institutions and while we limit the amount of credit exposure to any one institution, we could be subject to credit risks from concentration of investments in a single fund as well as credit risks arising from adverse conditions in the financial markets as a whole.

16. FAIR VALUE MEASUREMENTS

ASC 820, “Fair Value Measures” establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The three levels of the fair value hierarchy are as follows:

Level 1: Quoted prices for identical assets or liabilities in active markets which we can access

Level 2: Observable inputs other than those described in Level 1

Level 3: Unobservable inputs

The following table summarizes financial assets and financial liabilities carried at fair value and measured on a recurring basis as of December 31, 2017 and 2016, segregated by classification within the fair value hierarchy (in thousands):



			Fair Value Measurements
	Total		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
December 31, 2017:
Assets:
Available-for-sale securities	$	26	$	26	$	-	$	-
Restricted cash equivalents		1,000		1,000		-		-
Liabilities:
Secured contingent payment obligation		15,896		-		-		15,896


December 31, 2016:
Assets:
Available-for-sale securities	$	14	$	14	$	-	$	-
Restricted cash equivalents		911		911		-		-
Liabilities:
Secured contingent payment obligation		14,185		-		-		14,185

For the years ended December 31, 2017 and 2016, respectively, we had no transfers of assets or liabilities between the levels of the hierarchy. We determine the fair value of our available-for-sale securities and restricted cash equivalents using a market approach based on quoted prices in active markets (Level 1 inputs).

In 2016, we recognized a secured contingent payment obligation upon our receipt of proceeds from BKI for funding of certain patent-related actions (see Note 8). The fair value of the contingent payment obligation at December 31, 2017 was estimated at $15.9 million using a probability-weighted income approach based on various cash flow scenarios as to the outcome of patent-related actions both in terms of timing and amount, discounted to present value using a risk-adjusted rate. The contingent payment obligation does not have a fixed duration; however our cash flow projections assume a duration ranging from 2018 through 2021. The assumed cash outflows range from $0 to $34 million and the cash flow

scenarios have probabilities of 0% to 30% . We used a risk-adjusted discount rate of approximately 16% , based on a five year risk-free rate of approximately 2% as adjusted by 8% for credit risk and 6% for litigation inherent risk. Changes in any of these Level 3 inputs could result in a higher or lower fair value measurement. For example, a decrease in the risk-adjusted discount rate from 16% to 8% would result in an increase in the fair value of approximately $3 million. Refer to Note 8 for a reconciliation of our secured contingent payment obligation measured at estimated fair value for the years ended December 31, 2017 and 2016.

Item 9A. Co ntrols and Procedures.

Evaluation of Disclosure Controls and Procedures

Under Rules 13a-15(e) and 15d-15(e) of the Exchange Act, “disclosure controls and procedures” are controls and other procedures that are designed to ensure that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified under the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to our management, including our chief executive officer and our chief financial officer, as appropriate to allow timely decisions regarding required disclosures. Our management, with the participation of our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2017.

Based on such evaluation, our chief executive officer and our chief financial officer have concluded that as of December 31, 2017, our disclosure controls and procedures were effective.

Managemen t’s Report on Internal Control o ver Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting. Under Rules 13a-15(f) and 15d-15(f) of the Exchange Act, “internal control over financial reporting’’ is defined as a process designed by, or under the supervision of, our chief executive officer and our chief financial officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Internal control over financial reporting includes policies and procedures that pertain to the maintenance of records, that in reasonable detail, accurately and fairly reflect our transactions and our dispositions of assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with generally accepted accounting; provide reasonable assurance that receipts and expenditures of the company are made only in accordance with authorizations of management and directors; and provide reasonable assurance regarding the prevention or the timely detection of the unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on our financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management, with the participation of our chief executive officer and our chief financial officer, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2017 using the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on this evaluation, management concluded, as of December 31, 2017, our internal control over financial reporting was effective.

Changes in Internal Control over Financial Reporting

We implemented a number of internal controls related to inventory management, sales, and accounts receivable in the fourth quarter of 2017.

Other than as noted above, there were no changes in our internal control over financial reporting during the fiscal quarter ended December 31, 2017 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
