ITEM 1. BUSINESS
ITEM 1. BUSINESS
Company Overview and Business Model
Luna Innovations Incorporated ("we" or the "Company") is a leader in advanced optical technology, providing high performance fiber optic test, measurement and control products for the telecommunications and photonics industries; and distributed fiber optic sensing solutions that measure, or “sense,” the structures for industries ranging from aerospace, automotive, energy, oil and gas, security and infrastructure.
Our communications test and control products help customers test their fiber optic networks and assemblies with speed and precision in both lab and production environments, accelerating the development of fiber optic products and assuring accurate testing of optical components like photonic integrated circuits ("PICs") and coherent receivers, which are both critical elements of meeting the world’s exponentially growing demand for bandwidth. Our distributed fiber optic sensing products help designers and manufacturers more efficiently develop new and innovative products by measuring stress, strain, and temperature at a high resolution for new designs or manufacturing processes. In addition, our distributed fiber optic sensing products ensure the safety and structural integrity or operational health of critical assets in the field, by monitoring stress, strain, and vibration in large civil and industrial infrastructure such as bridges, roads, pipelines and borders. We also provide applied research services, typically under research programs funded by the U.S. government, in areas of sensing and instrumentation, advanced materials, optical technologies and health sciences.
We are organized into two main reporting segments, our Lightwave segment and our Luna Labs segment. Our Lightwave segment consists of our fiber optics testing, measurement and sensing solutions. Our Lightwave segment revenues represented approximately 71% and 70% of our total revenues for the years ended December 31, 2020 and 2019, respectively.
Our Luna Labs segment performs applied research principally in the areas of sensing and instrumentation, advanced materials, optical technologies and health sciences. Our Luna Labs segment comprised approximately 29% and 30% of our total revenues for the years ended December 31, 2020 and 2019, respectively. Most of the government funding for our Luna Labs segment is derived from the Small Business Innovation Research ("SBIR") program coordinated by the U.S. Small Business Administration ("SBA").
Our SBIR research is focused on technological areas with commercial potential and we strive to commercialize any resulting scientific advancements. For the year ended December 31, 2020, approximately 32% of our total revenues were generated under the SBIR program, compared to 35% for the year ended December 31, 2019.
For the years ended December 31, 2020 and 2019, 35% and 40%, respectively, of our total revenues were derived from the U.S. government.
Acquisitions
OptaSense Holdings Limited
On December 3, 2020, we acquired OptaSense Holdings Limited ("OptaSense") for $38.9 million, or £29.0 million, in cash. OptaSense, based in Farnborough, United Kingdom ("UK") and formerly owned by QinetiQ Holdings Limited, is a market leader in fiber optic distributed monitoring solutions for pipelines, oilfield services, security, highways and railways, and in power and utilities monitoring systems. The acquisition of OptaSense provided us with important distributed acoustic sensing ("DAS") intellectual property and products. OptaSense's technology and products and geographic footprint are highly complementary to our Lightwave segment which we believe will accelerate our technology roadmap and overall growth.
General Photonics Corporation
On March 1, 2019, we acquired all of the outstanding stock of General Photonics Corporation ("GP"), a leading provider of innovative components, modules and test equipment focused on the generation, measurement and control of polarized light critical in fiber optic-based applications for aggregate consideration of $20.0 million, inclusive of $19.0 million paid at closing and $1.0 million of contingent consideration paid in 2020 related to certain earn-out provisions.
Lightwave
Our Lightwave segment develops, manufactures and markets distributed fiber optic sensing products and fiber optic communications test and control products. We develop and commercialize our fiber optic technology for sensing applications for aerospace, automotive, energy and infrastructure as well as for test and measurement applications in the telecommunications and data communications industries. Our Lightwave segment also performs applied research principally in the areas of optical and terahertz technologies.
Our key initiative for long term growth is to become a leading provider of fiber optic test, measurement, control and sensing equipment. The acquisition of OptaSense added distributed acoustic sensing technology to our existing suite of sensing products and provided for expansion into high-growth markets such as security and perimeter detection, smart infrastructure monitoring and oil and gas. Our products have historically been strong in long-range, discrete sensing and short range, fully distributed sensing which are best when specific, known locations needed to be monitored. OptaSense's product offering has helped us fill a gap for long range, fully distributed measurement, which is best for applications where signals can occur anywhere along the length of the sensor.
Our primary product lines in our Lightwave segment are described in more detail below.
Communications Test and Photonic Controls Products
Test and Measurement Equipment for Fiber Optic Components and Sub-Assemblies
Our product lines in the optical test and measurement domain include our Optical Vector Analyzer, our Optical Backscatter Reflectometer, and our Phoenix family of tunable lasers.
Our optical test and measurement products primarily serve the telecommunications industry, as well as provide valuable applications in other fields. Our test and measurement products test and monitor the integrity of fiber optic network components and sub-assemblies. These products are designed for manufacturers and suppliers of optical components and sub-assemblies allowing them to reduce development, test and production costs and improve the quality of their products. Our products are particularly useful for characterizing and testing photonic integrated circuits, such as silicon photonics components, which are a critical technology enabling the growing worldwide demand for internet connectivity. Most manufacturers and suppliers of optical components and modules currently use a combination of different types of optical test equipment to measure performance and identify failures in optical networks, such as bad splices, bends, crimps and other reflective and non-reflective events that can cause defects and negatively impact product performance. Our optical test equipment products eliminate the need to employ multiple test products by addressing all stages of the end user’s product development lifecycle, including design verification, component qualification, assembly process verification and failure analysis.
Polarization Control
Our polarization control products include components, modules and instruments to measure, manage and control polarization and group delay in fiber optic networks. Our proprietary fiber optic squeezing technology enables a high- performance polarization control and measurement system for the accurate measurement of polarization properties of light sources and optical materials. We also manufacture and sell fiber optic coils for use in gyroscopes.
Tunable Lasers
Our swept tunable lasers are integrated into current and new products to help customers build faster, more flexible and cost-effective test and measurement products. Our laser has desirable properties in the quality of the laser light produced, the speed at which it can operate, the small size of the package, and the environmental conditions in which it can operate, making it possible to bring these capabilities out of the laboratory, and into more demanding environments such as aircraft structural health monitoring, automotive manufacturing, green energy and industrial applications.
Sensing and Non-Destructive Test Products
ODiSI Sensing Solution
Our ODiSI products provide fully distributed strain and temperature measurements delivering an extraordinary amount of data by using an optical fiber as a continuous sensor to produce measurements every millimeter for a sensor up to 50 meters in length. Compared to traditional sensing methods, such as electrical strain gages, this technology provides greater insight into the performance, tolerances and failure mechanisms of composite structures and vehicles and can be integrated into locations and environments not accessible with traditional sensors. We believe our ODiSI products provide exceptional value to the
aerospace and automotive industries as they continue to adopt electrification and move to lighter weight systems made of composite structures.
ODiSI incorporates multiple channels of fiber optic sensors whose inputs are integrated through an advanced measurement system and software using fiber optic sensing technology with our innovative monitoring system that allows several thousand sensors to be networked along a single optical fiber.
Hyperion Sensing Solution
Our Hyperion sensing products expand our capabilities in fiber optic sensing by providing distributed sensing using hundreds of Fiber-Bragg Grating ("FBG") or Extrinsic Fabry-Perot ("FP") sensors integrated into long-rage sensors of up to 40km in length, measured at sampling rates up to 5KHz. Hyperion enables rapid full-spectrum data acquisition and flexible peak detect algorithms of FBGs, Long Period FBGs and FP sensors with low-latency access to data for closed-loop feedback applications. Our Hyperion products target fiber optic sensing applications that require more dynamic measurement capabilities or longer distances than provided by our ODiSI platform, like monitoring of large, civil and industrial infrastructure.
Terahertz Sensing Systems
Our Terametrix terahertz ("THz") gauging and imaging product line uses pulsed THz waves to provide precise single- and multi-layer thickness, density, basis weight and caliper thickness measurements to serve the industrial, non-destructive testing, and research markets. Similar to x-ray images, THz wavelengths penetrate through most non-conductive materials and can easily reveal imperfections such as voids, cracks, and density variations. THz offers a significant advantage over x-rays because the radiation is non-ionizing and thus is completely safe. THz technology, unlike other traditional methods, is non-contact, works with both opaque and translucent materials, and works well for multilayer structures. The ability to accurately measure layer thickness is critical for ensuring consistent quality, minimizing defects and reducing material usage for products such as tubing, tires, plastic bottles, adhesives and coatings. Handheld THz sensors can measure and scan specialty coatings and multilayer structures to check thickness consistency and locate subsurface defects. THz systems can be used to inspect the high-performance coatings used on military aircraft, verifying thickness of applied coatings with submicron accuracy.
Distributed Acoustic Sensing Products
OptaSense
Our line of advanced DAS interrogator units deliver superior measurements for a wide range of applications from advanced industrial monitoring through high performance geophysical measurements. Applications of these units include real-time pipeline monitoring preventing disruption flow, advance monitoring and evaluation of reservoir and wellbore to reduce risk and optimize recovery, real-time information detection on highways and railways for traffic management and ensuring safety, cost-effective surveillance of borders and national assets and the precise detection of faults in power and utility infrastructure. Our DAS operations include a market leading laser technology company that supports and vertically integrates the most critical element of the DAS system, its internal laser.
Sales and Marketing
We primarily market our fiber optic test, measurement and control products to telecommunications companies, defense agencies, government system integrators, researchers, original equipment manufacturers, distributors, testing labs and strategic partners worldwide. We have a regional sales force that markets and sells our products directly as well as through manufacturer representative organizations to customers in North America and through partner and distribution channels for sales outside of North America, including the EMEA, LATAM and APAC regions. We have a dedicated sales force for direct marketing of our distributed sensing products, with an initial focus on customers in the automotive, aerospace, and energy industries.
We sell and market our THz instruments primarily to original equipment manufacturers through a mix of technical sales engineers, value added resellers and independent sales representatives. We market these products and capabilities through industry specific channels, including the internet, industry trade shows and through trade journals.
We believe that we provide a high level of support in developing and maintaining our long-term relationships with our customers. Customer service and support are provided through our offices and those of our partners that are located throughout the world.
Luna Labs
We provide applied research for customers in our primary areas of focus, including sensing and materials such as coatings, adhesives, composites and bio-engineered materials. We generally compete to win contracts in these areas on a fee-for-service basis. Our Luna Labs segment has a successful track record of evaluating innovative technologies to address the needs of our customers.
We seek to maximize the benefits of our contract research business by generating revenue and identifying promising technologies to develop. We focus primarily on opportunities in which we develop intellectual property rights in areas that we believe we can commercialize. We take a disciplined approach to contract research to ensure the costs of contracts we undertake will be fully reimbursed. We believe this model is cost-efficient and significantly reduces our development risk by enabling us to defray the development costs of higher risk technology with third-party funding.
While we conduct our applied research on a fee-for-service basis for third parties, we seek to retain full or partial rights to the technologies and patents we develop under these contracts to continuously enlarge and strengthen our intellectual property portfolio. New technology that we develop may complement our existing technologies and enable us to develop applications and products that were previously not possible. In addition, the new technologies we develop may have commercial markets beyond the scope of the applications originally contemplated in the contract research stage, and we endeavor to capture the value of those opportunities. Funded research and development within this business segment was $23.6 million and $21.4 million for the years ended December 31, 2020 and 2019, respectively.
Each year, U.S. government federal agencies and departments are required to allocate a portion of their grant awards for SBIR-qualified organizations. SBIR contracts include Phase I feasibility contracts of up to $225,000 and Phase II proof-of-concept contracts, which can be as high as $1,500,000. We have won three National Tibbetts Awards from the SBA for outstanding SBIR performance. We have also won research contracts outside the SBIR program from corporations and government entities. These contracts typically have a longer duration and higher value than SBIR grants. In the future, we seek to derive a larger portion of our contract research revenues from contracts outside of the SBIR program.
Materials
We are actively developing a wide variety of materials. For example, we have developed a range of coatings, including both hydrophobic and superoleophobic coatings. These coatings are being evaluated for use in a number of applications. Other coatings under development include anti-corrosion and damage-indicating coatings.
We are also working on a variety of bioengineered materials for homeostatic agents and wound healing. These materials must be approved by the FDA or similar foreign regulatory agencies before they can be marketed, which we do not expect to occur for at least several years, if at all.
Sensing
Our Luna Labs segment also performs a significant amount of applied research towards developing new sensors. This includes sensors for the purpose of corrosion, temperature, strain, pressure, structural health and chemical detection. Much of the work is directed to harsh environments and uses optics. Examples include measuring temperature and neutron flux in nuclear reactors, pressure and temperature in gas turbines and temperatures of cryogenic lines. The effort utilizes both discrete and distributed sensors. Our technology development work in this area is closely aligned with our Lightwave segment and is directed at advancing the technology and the development of new applications.
Intellectual Property
We seek patent protection on inventions that we consider important to the operations of our business. We rely on a combination of patent, trademark, copyright and trade secret laws in the United States and other jurisdictions, as well as confidentiality procedures and contractual provisions to protect our proprietary technology and our brand. We control access to our proprietary technology and enter into confidentiality and invention assignment agreements with our employees and consultants and confidentiality agreements with other third parties.
Our success depends in part on our ability to develop patentable products and obtain, maintain and enforce patent and trade secret protection for our products, including successfully defending our patents against third-party challenges both in the United States and in other countries. We will only be able to protect our technologies from unauthorized use by third parties to the extent that we own or have licensed valid and enforceable patents or trade secrets that cover them. Furthermore, the degree of future protection of our proprietary rights is uncertain because we may not be able to obtain patent protection on some or all
of our technology and because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage.
Currently, we own or license approximately 527 U.S. and international patents and approximately 122 U.S. and international patent applications. Our issued patents generally have terms that are scheduled to expire between 2021 and 2037. The patents scheduled to expire in 2021 are not expected to have a significant impact on our revenues or results of operations. Patents may not be issued for any pending or future pending patent applications owned by or licensed to us. Claims allowed under any issued patent or future issued patent owned or licensed by us may not be valid or sufficiently broad to protect our technologies. Any issued patents owned by or licensed to us now or in the future may be challenged, invalidated or circumvented, and, in addition, the rights under such patents may not provide us with competitive advantages. In addition, competitors may design around our technology or develop competing technologies. To the extent we elect to pursue, intellectual property rights may also be unavailable or limited in some foreign countries, which could make it easier for competitors to capture or increase their market share with respect to related technologies.
A discussion of our material in-licensed patents is set forth below.
Shape Sensing Patents
As a part of our sale of assets associated with our fiber optic shape sensing technology in the medical field to Intuitive Surgical, Inc. ("Intuitive") in 2014, we transferred our related patents to Intuitive. Also, as a part of this transaction, we entered into a revocable license agreement with Intuitive pursuant to which we have the right to use all of our transferred technology outside the field of medicine and in respect of our existing non-shape sensing products in certain non-robotic medical fields. Two U.S. patents that we now license back from Intuitive cover the use of optical frequency domain reflectometry and multiple, closely spaced Bragg gratings for shape sensing, and the use of the inherent scatter as a strain sensor for shape sensing. These two patents expire in July 2025. We also license back from Intuitive patents and patent applications that cover certain refinements to the measurements covered in the foregoing two patents and related technologies, which are necessary in order to achieve the necessary accuracies for medical and other applications. These patent applications were filed in the United States, the European Patent Office, China, India, Russia, Brazil, Japan, Indonesia and elsewhere. These patents and patent applications can support other nonmedical applications of our fiber optic shape sensing technology.
Coherent
In December 2006, we entered into an asset transfer and license agreement with Coherent, Inc. Under the agreement, we acquired the rights to manufacture Coherent’s “Iolon” brand of swept tunable lasers as well as certain manufacturing equipment and inventory previously used by Coherent to manufacture the lasers. We continue to enhance, produce and market these lasers under our “Phoenix” brand. Under this agreement, Coherent granted non-exclusive licenses to us for certain U.S. patents and other intellectual property rights owned or controlled by Coherent for making, having made, using, importing, selling and offering for sale the lasers. This agreement expired in 2016. However, the patent licenses became fully paid and perpetual, as we fulfilled our royalty obligations during the 10-year period and the license to the other intellectual property rights is perpetual. These U.S. patents expire between 2020 and 2022. As consideration, we paid Coherent a total of $1.3 million in addition to paying royalties on net sales of products sold by us that incorporate the lasers or that are manufactured using the intellectual property covered by the licenses.
The Phoenix laser is a miniaturized, external-cavity laser offering high performance in a compact footprint and is applicable to a range of fiber optic test and measurement, instrumentation, and sensing applications. These products employ frequency-tuned lasers to measure various aspects of the transmission properties of telecommunications fiber optic components and systems. Lasers are also used in fiber optic sensing applications such as distributed strain and temperature mapping, and distributed measurement of shape. We currently use these lasers within our ODiSI platform of products, our fiber optic shape sensing products and certain of our backscatter reflectometer products, and we also sell variations of the Phoenix laser as standalone products. Under our agreements related to our sale of assets to Intuitive, we have certain obligations to supply Intuitive with these lasers.
Divestitures
Sale of High-Speed Optical Receiver ("HSOR") Business
On August 9, 2017, we completed the sale of our HSOR business, which was part of our Lightwave segment, to Macom Technology Solutions Inc. ("Macom") for an initial purchase price of $33.5 million, of which $29.5 million in cash has been received, and $4.0 million was placed into escrow until December 15, 2018 for possible working capital adjustments to the purchase price and potential satisfaction of certain post-closing indemnification obligations. The HSOR business was a
component of the operations of Advanced Photonix, Inc., which we acquired in May 2015. In December 2018, we received $1.5 million of the escrow amount. In March 2020, we settled a dispute regarding the remaining $2.5 million in escrow resulting in us receiving $0.6 million and Macom receiving $1.9 million. For the year ended December 31, 2020, we have recorded a loss from discontinued operations of $1.4 million, net of income tax benefit, to reflect the settlement of the dispute.
Sale of Luna Optoelectronics
In July 2018 we sold substantially all of the assets associated with our custom optoelectronic components and sub-assemblies business for total cash consideration of $17.5 million, paid at closing, in addition to contingent consideration of up to $1.0 million. The contingent consideration is subject to the optoelectronic business achieving specified revenue targets for the 18-month period following the closing date. We did not receive any of the additional $1.0 million of consideration because the minimum revenue targets were not achieved.
Corporate History
We were incorporated in the Commonwealth of Virginia in 1990 and reincorporated in the State of Delaware in April 2003. We completed our initial public offering in June 2006. Our executive offices are located at 301 1st St SW, Suite 200, Roanoke, Virginia 24011 and our main telephone number is (540) 769-8400.
Competition
We compete with a variety of companies in several different product markets. The products that we have developed or are currently developing will compete with other technologically innovative products, as well as products incorporating conventional materials and technologies. We expect that we will compete with companies that manufacture test and measurement equipment for a wide range of industries, including aerospace, defense, healthcare, telecommunications, energy (including oil and gas and green energy), industrial measurement, and security applications. Although there can be no assurance that we will continue to do so, we believe that we compete favorably in these areas because our products leverage advanced technologies to offer superior performance. If we are unable to effectively compete in these areas in the future, we could lose business to our competitors, which could harm our operating results.
We also compete, or will compete, for government, university and corporate research contracts relating to a broad range of technologies. Competition for contract research is intense and the industry has few barriers to entry. We compete against a number of in-house research and development departments of major corporations, as well as a number of small, limited-service contract research providers and companies backed by large venture capital firms. The contract research industry continues to experience consolidation, which has resulted in greater competition for clients. Increased competition might lead to price and other forms of competition that could harm our operating results. We compete for contract research on the basis of a number of factors, including reliability, past performance, expertise and experience in specific areas, scope of service offerings, technological capabilities and price.
Government Regulation
Qualification for Small Business Innovation Research Grants
SBIR is a highly competitive program that encourages small businesses to explore their technological potential and provides them with incentives to commercialize their technologies by funding research that might otherwise be prohibitively expensive or risky for companies like us. As noted above, we presently derive a significant portion of our revenue from this program, but we must continue to qualify for the SBIR program in order to be eligible to receive future SBIR awards. The eligibility requirements are:
•Ownership. The company must be more than 50 percent owned and controlled by U.S. citizens or permanent resident aliens, or owned by an entity that is itself more than 50 percent owned and controlled by U.S. citizens or permanent resident aliens; and
•Size. The company, including its affiliates, cannot have more than 500 employees.
These requirements are set forth in the SBA’s regulations and are interpreted by the SBA’s Office of Hearings and Appeals. In determining whether we satisfy the more than 50% ownership requirement, agreements to merge, stock options, convertible debt and other similar instruments are given “present effect” by the SBA as though the underlying security were actually issued unless the exercisability or conversion of such securities is speculative, remote or beyond the control of the security holder. We therefore believe our outstanding options and warrants held by eligible individuals may be counted as outstanding equity for purposes of meeting the more than 50% equity ownership requirement. We believe that we are in compliance with the SBA ownership requirements.
In addition, to be eligible for SBIR contracts, the number of our employees, including those of any entities that are considered to be affiliated with us, cannot exceed 500. As of December 31, 2020, we, including all of our divisions, had 426 full- and part-time employees. In determining whether we have 500 or fewer employees, the SBA may count the number of employees of entities that are large stockholders who are “affiliated” or have the power to control us. In determining whether firms are affiliated, the SBA evaluates factors such as stock ownership and common management, but it ultimately may make its determination based on the totality of the circumstances. Eligibility protests can be raised to the SBA by a competitor or by the awarding contracting agency. If we grow larger, and if our ownership becomes more diversified, we may no longer qualify for the SBIR program, and we may be required to seek alternative sources and partnerships to fund some of our research and development costs. Additional information regarding these risks may be found below in “Risk Factors.”
Environmental, Health and Safety Regulation
Our facilities and current and proposed activities involve the use of a broad range of materials that are considered hazardous under applicable laws and regulations. Accordingly, we are subject to a number of domestic and foreign laws and regulations and other requirements relating to employee health and safety, protection of the environment, product labeling and product take back. Regulated activities include the storage, use, transportation and disposal of, and exposure to, hazardous or potentially hazardous materials and wastes. Our current and proposed activities also include potential exposure to physical hazards associated with work environment and equipment. We could incur costs, fines, civil and criminal penalties, personal injury and third-party property damage claims, or we could be required to incur substantial investigation or remediation costs, if we were to violate or become liable under environmental, health and safety laws and regulations or requirements. Liability under environmental, health and safety laws can be joint and several and without regard to fault. There can be no assurance that violations of environmental, health and safety laws will not occur in the future as a result of the inability to obtain permits in a timely manner, human error, equipment failure or other causes. Environmental, health and safety laws could also become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business. Further, violations of present and future environmental, health and safety laws could restrict our ability to expand facilities and pursue certain technologies, as well as require us to acquire costly equipment or to incur potentially significant costs to comply with environmental, health and safety regulations and other requirements.
We have made, and will continue to make, expenditures to comply with current and future environmental, health and safety laws. We anticipate that we could incur additional capital and operating costs in the future to comply with existing environmental, health and safety laws and new requirements arising from new or amended statutes and regulations. In addition, because the applicable regulatory agencies have not yet promulgated final standards for some existing environmental, health and safety programs, we cannot at this time reasonably estimate the cost for compliance with these additional requirements. The amount of any such compliance costs could be material. We cannot predict the impact that future regulations will impose upon our business.
Employees
As of December 31, 2020, we had approximately 411 full-time employees and 15 part-time employees, including approximately 179 in research, development and engineering positions, approximately 140 in operations, approximately 56 in sales and marketing, and approximately 51 in administrative positions. None of our employees are covered by a collective bargaining agreement, and we consider our relationship with our employees to be good.
Backlog
Our backlog of purchase orders received for which the related goods have not been shipped or recognized as revenue, primarily within our Lightwave segment, was $28.2 million and $16.1 million at December 31, 2020 and 2019, respectively.
We have historically had a backlog of contracts, primarily within our Luna Labs segment, for which work has been scheduled, but for which a specified portion of work has not yet been completed. The approximate value of our backlog was $26.8 million and $31.3 million at December 31, 2020 and 2019, respectively.
We define backlog as the dollar amount of obligations payable to us under negotiated contracts upon completion of a specified portion of work that has not yet been completed, exclusive of revenues previously recognized for work already performed under these contracts, if any. Total backlog includes funded backlog, which is the amount for which money has been directly authorized by the U.S. government or for which a purchase order has been received from a commercial customer, and unfunded backlog, which represents firm orders for which funding has not yet been appropriated. Unfunded backlog was $5.0 million and $2.2 million as of December 31, 2020 and 2019, respectively. Indefinite delivery and quantity contracts and unexercised options are not reported in total backlog. Our backlog is subject to delays or program cancellations that may be beyond our control.

ITEM 1A. RISK FACTORS
ITEM 1A. RISK FACTORS
You should carefully consider the risks described below before deciding whether to invest in our common stock. The risks described below are not the only ones we face. Additional risks not presently known to us or that we currently believe are immaterial may also impair our business operations and financial results. If any of the following risks actually occurs, our business, financial condition or results of operations could be adversely affected. In such case, the trading price of our common stock could decline and you could lose all or part of your investment. Our filings with the Securities and Exchange Commission also contain forward-looking statements that involve risks or uncertainties. Our actual results could differ materially from those anticipated or contemplated by these forward-looking statements as a result of a number of factors, including the risks we face described below, as well as other variables that could affect our operating results. Past financial performance should not be considered to be a reliable indicator of future performance, and investors should not use historical trends to anticipate results or trends in future periods.
RISKS RELATING TO OUR BUSINESS
Our technology is subject to a license from Intuitive Surgical, Inc., which is revocable in certain circumstances. Without this license, we cannot continue to market, manufacture or sell our fiber-optic products.
As a part of the sale of certain assets to Intuitive Surgical, Inc. ("Intuitive") in 2014, we entered into a license agreement with Intuitive pursuant to which we received rights to use all of our transferred technology outside the field of medicine and in respect of our existing non-shape sensing products in certain non-robotic medical fields. This license back to us is revocable if after notice and certain time periods, we were to (i) challenge the validity or enforceability of the transferred patents and patent applications, (ii) commercialize our fiber optical shape sensing and localization technology in the field of medicine (except to perform on a development and supply project for Hansen Medical, Inc.), (iii) violate our obligations related to our ability to sublicense in the field of medicine or (iv) violate our confidentiality obligations in a manner that advantages a competitor in the field of medicine and not cure such violation. Maintaining this license is necessary for us to conduct our fiber-optic products business, both for our telecom products and our ODiSI sensing products. If this license were to be revoked by Intuitive, we would no longer be able to market, manufacture or sell these products which could have a material adverse effect on our operations.
We depend on third-party vendors for specialized components in our manufacturing operations, making us vulnerable to supply shortages and price fluctuations that could harm our business.
We primarily rely on third-party vendors for the manufacture of the specialized components used in our products. The highly specialized nature of our supply requirements poses risks that we may not be able to locate additional sources of the specialized components required in our business. For example, there are few manufacturers who produce the special lasers used in our optical test equipment. Our reliance on these vendors subjects us to a number of risks that could negatively affect our ability to manufacture our products and harm our business, including interruption of supply, including as a result of the COVID-19 pandemic. Although we are now manufacturing tunable lasers in low-rate initial production, we expect our overall reliance on third-party vendors to continue. Any significant delay or interruption in the supply of components, or our inability to obtain substitute components or materials from alternate sources at acceptable prices and in a timely manner could impair our ability to meet the demand of our customers and could harm our business.
We depend upon outside contract manufacturers for a portion of the manufacturing process for some of our products. Our operations and revenue related to these products could be adversely affected if we encounter problems with these contract manufacturers.
Many of our products are manufactured internally. However, we also rely upon contract manufacturers to produce the finished portion of certain lasers. Our reliance on contract manufacturers for these products makes us vulnerable to possible capacity constraints and reduced control over delivery schedules, manufacturing yields, manufacturing quality control and costs. If the contract manufacturer for our products were unable or unwilling to manufacture our products in required volumes and at high quality levels or to continue our existing supply arrangement, we would have to identify, qualify and select an acceptable alternative contract manufacturer or move these manufacturing operations to internal manufacturing facilities. An alternative contract manufacturer may not be available to us when needed or may not be in a position to satisfy our quality or production requirements on commercially reasonable terms, including price. Any significant interruption in manufacturing our products, including as a result of the COVID-19 pandemic, would require us to reduce the supply of products to our customers, which in turn would reduce our revenue, harm our relationships with the customers of these products and cause us to forego potential revenue opportunities.
As a provider of contract research to the U.S. government, we are subject to federal rules, regulations, audits and investigations, the violation or failure of which could adversely affect our business.
We must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. government contracts. Government contract laws and regulations affect how we do business with our government customers and, in some instances, impose added costs on our business. A violation of a specific law or regulation could result in the imposition of fines and penalties, termination of our contracts or debarment from bidding on contracts. In some instances, these laws and regulations impose terms or rights that are more favorable to the government than those typically available to commercial parties in negotiated transactions. For example, the U.S. government may terminate any of our government contracts and, in general, subcontracts, at their convenience, as well as for default based on performance.
In addition, U.S. government agencies, including the Defense Contract Audit Agency and the Department of Labor, routinely audit and investigate government contractors. These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. The U.S. government also may review the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed, while such costs already reimbursed must be refunded. If an audit uncovers the inclusion of certain claimed costs deemed to be expressly unallowable, or improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government. In addition, our reputation could suffer serious harm if allegations of impropriety were made against us.
In addition to the risk of government audits and investigations, U.S. government contracts and grants impose requirements on contractors and grantees relating to ethics and business practices, which carry civil and criminal penalties including monetary fines, assessments, loss of the ability to do business with the U.S. government and certain other criminal penalties.
We may also be prohibited from commercially selling certain products that we develop under our Lightwave and Luna Labs segments or related products based on the same core technologies if the U.S. government determines that the commercial availability of those products could pose a risk to national security. For example, certain of our wireless technologies have been classified as secret by the U.S. government and as a result we cannot sell them commercially. Any of these determinations would limit our ability to generate product sales and license revenues.
We rely and will continue to rely on contracts and grants awarded under the SBIR program for a significant portion of our revenues. A finding by the SBA that we no longer qualify to receive SBIR awards could adversely affect our business.
We compete as a small business for some of our government contracts. Our revenues derived from the SBIR program account for a significant portion of our consolidated total revenues, and contract research, including SBIR contracts, will remain a significant portion of our consolidated total revenues for the foreseeable future. For the years ended December 31, 2020 and 2019, revenues generated under the SBIR program represented 32% and 35%, respectively, of our total revenues.
We may not continue to qualify to participate in the SBIR program or to receive new SBIR awards from federal agencies. In order to qualify for SBIR contracts and grants, we must meet certain size and ownership eligibility criteria. These eligibility criteria are applied as of the time of the award of a contract or grant. A company can be declared ineligible for a contract award as a result of a size challenge filed with the SBA by a competitor or a federal agency.
In order to be eligible for SBIR contracts and grants, under current SBA rules we must be more than 50% owned and controlled by individuals who are U.S. citizens or permanent resident aliens, and/or other small business concerns (each of which is more than 50% owned and controlled by individuals who are U.S. citizens or permanent resident aliens) or certain
qualified investment companies. In the event our institutional ownership significantly increases, either because of increased buying by institutions or selling by individuals, we could lose eligibility for new SBIR contracts and grants.
Also, in order to be eligible for SBIR contracts and grants, the number of our employees, including those of any entities that are considered to be affiliated with us, cannot exceed 500. As of December 31, 2020, we had approximately 426 full-time and part-time employees. In determining whether we are affiliated with any other entity, the SBA may analyze whether another entity controls or has the power to control us. Carilion Clinic is our largest institutional stockholder.
Since early 2011, a formal size determination by the SBA that focused on whether or not Carilion is or was our affiliate has been outstanding. Although we do not believe that Carilion has or had the power to control our company, we cannot assure you that the SBA will interpret its regulations in our favor on this question. If the SBA were to make a determination that we are or were affiliated with Carilion, we would exceed the size limitations, as Carilion has over 500 employees. In that case, we would lose eligibility for new SBIR contracts and grants and other awards that are set aside for small businesses based on the criterion of number of employees, and the relevant government agency would have the discretion to suspend performance on existing SBIR grants. The loss of our eligibility to receive SBIR awards would have a material adverse impact on our revenues, cash flows and our ability to fund our growth.
Moreover, as our business grows, it is foreseeable that we will eventually exceed the SBIR size limitations, in which case we may be required to seek alternative sources of revenues or capital.
A decline in government research contract awards or government funding for existing or future government research contracts, including SBIR contracts, could adversely affect our revenues, cash flows and ability to fund our growth.
Contract research revenue within the Lightwave and Luna Labs segment revenues, which consists primarily of government-funded research, accounted for 35% and 37% of our consolidated total revenues for the years ended December 31, 2020 and 2019, respectively. As a result, we are vulnerable to adverse changes in our revenues and cash flows if a significant number of our research contracts and subcontracts were to be simultaneously delayed or canceled for budgetary, performance or other reasons. For example, the U.S. government may cancel these contracts at any time without cause and without penalty or may change its requirements, programs or contract budget, any of which could reduce our revenues and cash flows from U.S. government research contracts. Our revenues and cash flows from U.S. government research contracts and subcontracts could also be reduced by declines or other changes in U.S. defense, homeland security and other federal agency budgets. In addition, we compete as a small business for some of these contracts, and in order to maintain our eligibility to compete as a small business, we, together with any affiliates, must continue to meet size and revenue limitations established by the U.S. government.
Our contract research customer base includes government agencies, corporations and academic institutions. Our customers are not obligated to extend their agreements with us and may elect not to do so. Also, our customers’ priorities regarding funding for certain projects may change and funding resources may no longer be available at previous levels.
In addition to contract cancellations and changes in agency budgets, our future financial results may be adversely affected by curtailment of or restrictions on the U.S. government’s use of contract research providers, including curtailment due to government budget reductions and related fiscal matters or any legislation or resolution limiting the number or amount of awards we may receive. These or other factors could cause U.S. defense and other federal agencies to conduct research internally rather than through commercial research organizations or direct awards to other organizations, to reduce their overall contract research requirements or to exercise their rights to terminate contracts. Alternatively, the U.S. government may discontinue the SBIR program or its funding altogether. Also, SBIR regulations permit increased competition for SBIR awards from companies that may not have previously been eligible, such as those backed by venture capital operating companies, hedge funds and private equity firms. Any of these developments could limit our ability to obtain new contract awards and adversely affect our revenues, cash flows and ability to fund our growth.
Our failure to attract, train and retain skilled employees or members of our senior management and to obtain necessary security clearances for such persons or maintain a facility security clearance would adversely affect our business and operating results.
The availability of highly trained and skilled technical and professional personnel is critical to our future growth and profitability. Competition for scientists, engineers, technicians and professional personnel is intense and our competitors aggressively recruit key employees. In the past, we have experienced difficulties in recruiting and hiring these personnel as a result of the tight labor market in certain fields. Any difficulty in hiring or retaining qualified employees, combined with our growth strategy and future needs for additional experienced personnel, particularly in highly specialized areas such as nanomaterial manufacturing and fiber optic sensing technologies, may make it more difficult to meet all of our needs for these employees in a timely manner. Although we intend to continue to devote significant resources to recruit, train and retain
qualified employees, we may not be able to attract and retain these employees, especially in technical fields in which the supply of experienced qualified candidates is limited, or at the senior management level. Any failure to do so would have an adverse effect on our business. Any loss of key personnel could have a material adverse effect on our ability to meet key operational objectives, such as timely and effective project milestones and product introductions, which in turn could adversely affect our business, results of operations and financial condition.
We provide certain services to the U.S. government that require us to maintain a facility security clearance and for certain of our employees and our board chairman to hold security clearances. In general, the failure for necessary persons to obtain or retain sufficient security clearances, any loss by us of a facility security clearance or any public reprimand related to security matters could result in a U.S. government customer terminating an existing contract or choosing not to renew a contract or prevent us from bidding on or winning certain new government contracts.
In addition, our future success depends in a large part upon the continued service of key members of our senior management team. We do not maintain any key-person life insurance policies on our officers. The loss of any members of our management team or other key personnel could seriously harm our business.
Our business is subject to the cyclical nature of the markets in which we compete and any future downturn may reduce demand for our products and revenue.
Many factors beyond our control affect our business, including consumer confidence in the economy, interest rates, fuel prices, health crises, such as the COVID-19 pandemic, and the general availability of credit. The overall economic climate and changes in Gross National Product growth have a direct impact on some of our customers and the demand for our products. We cannot be sure that our business will not be adversely affected as a result of an industry or general economic downturn.
Our customers may reduce capital expenditures and have difficulty satisfying liquidity needs because of continued turbulence in the U.S. and global economies, resulting in reduced sales of our products and harm to our financial condition and results of operations.
In particular, our historical results of operations have been subject to substantial fluctuations, and we may experience substantial period-to-period fluctuations in future results of operations. Any future downturn in the markets in which we compete could significantly reduce the demand for our products and therefore may result in a significant reduction in revenue or increase the volatility of the price of our common stock. Our revenue and results of operations may be adversely affected in the future due to changes in demand from customers or cyclical changes in the markets utilizing our products.
In addition, the telecommunications industry has, from time to time, experienced, and may again experience, a pronounced downturn. To respond to a downturn, many service providers may slow their capital expenditures, cancel or delay new developments, reduce their workforces and inventories and take a cautious approach to acquiring new equipment and technologies from original equipment manufacturers, which would have a negative impact on our business. Weakness in the global economy or a future downturn in the telecommunications industry may cause our results of operations to fluctuate from quarter-to-quarter and year-to-year, harm our business, and may increase the volatility of the price of our common stock.
Customer acceptance of our products is dependent on our ability to meet changing requirements, and any decrease in acceptance could adversely affect our revenue.
Customer acceptance of our products is significantly dependent on our ability to offer products that meet the changing requirements of our customers, including telecommunication, military, medical and industrial corporations, as well as government agencies. Any decrease in the level of customer acceptance of our products could harm our business.
Our products must meet exacting specifications, and defects and failures may occur, which may cause customers to return or stop buying our products.
Our customers generally establish demanding specifications for quality, performance and reliability that our products must meet. However, our products are highly complex and may contain defects and failures when they are first introduced or as new versions are released. Our products are also subject to rough environments as they are integrated into our customer products for use by the end customers. If defects and failures occur in our products, we could experience lost revenue, increased costs, including warranty expense and costs associated with customer support, delays in or cancellations or rescheduling of orders or shipments, product returns or discounts, diversion of management resources or damage to our reputation and brand equity, and in some cases consequential damages, any of which would harm our operating results. In addition, delays in our ability to fill product orders as a result of quality control issues may negatively impact our relationship with our customers. We cannot assure you that we will have sufficient resources, including any available insurance, to satisfy any asserted claims.
The markets for many of our products are characterized by changing technology which could cause obsolescence of our products, and we may incur substantial costs in delivering new products.
The markets for many of our products are characterized by changing technology, new product introductions and product enhancements, and evolving industry standards. The introduction or enhancement of products embodying new technology or the emergence of new industry standards could render existing products obsolete, and result in a write down to the value of our inventory, or result in shortened product life cycles. Accordingly, our ability to compete is in part dependent on our ability to continually offer enhanced and improved products.
The success of our new product offerings will depend upon several factors, including our ability to:
•accurately anticipate customer needs;
•innovate and develop new technologies and applications;
•successfully commercialize new technologies in a timely manner;
•price products competitively and manufacture and deliver products in sufficient volumes and on time; and
•differentiate our product offerings from those of our competitors.
Our inability to find new customers or retain existing customers could harm our business.
Our business is reliant on our ability to find new customers and retain existing customers. In particular, customers normally purchase certain of our products and incorporate them into products that they, in turn, sell in their own markets on an ongoing basis. As a result, the historical sales of these products have been dependent upon the success of our customers’ products and our future performance is dependent upon our success in finding new customers and receiving new orders from existing customers.
In several markets, the quality and reliability of our products are a major concern for our customers, not only upon the initial manufacture of the product, but for the life of the product. Many of our products are used in remote locations for higher value assembly, making servicing of our products unfeasible. Any failure of the quality or reliability of our products could harm our business.
Customer demand for our products is difficult to accurately forecast and, as a result, we may be unable to optimally match production with customer demand, which could adversely affect our business and financial results.
We make planning and spending decisions, including determining the levels of business that we will seek and accept, production schedules, inventory levels, component procurement commitments, personnel needs and other resource requirements, based on our estimates of customer requirements. The short-term nature of commitments by many of our customers and the possibility of unexpected changes in demand for their products reduce our ability to accurately estimate future customer requirements. On occasion, customers may require rapid increases in production, which can strain our resources, cause our manufacturing to be negatively impacted by materials shortages, necessitate higher or more restrictive procurement commitments, increase our manufacturing yield loss and scrapping of excess materials, and reduce our gross margin. We may not have sufficient capacity at any given time to meet the volume demands of our customers, or one or more of our suppliers may not have sufficient capacity at any given time to meet our volume demands. Conversely, a downturn in the markets in which our customers compete can cause, and in the past have caused, our customers to significantly reduce or delay the amount of products ordered or to cancel existing orders, leading to lower utilization of our facilities. Because many of our costs and operating expenses are relatively fixed, reduction in customer demand due to market downturns or other reasons would have a negative effect on our gross margin, operating income and cash flow.
Rapidly changing standards and regulations could make our products obsolete, which would cause our revenue and results of operations to suffer.
We design products to conform to our customers’ requirements and our customers’ systems may be subject to regulations established by governments or industry standards bodies worldwide. Because some of our products are designed to conform to current specific industry standards, if competing or new standards emerge that are preferred by our customers, we would have to make significant expenditures to develop new products. If our customers adopt new or competing industry standards with which our products are not compatible, or the industry groups adopt standards or governments issue regulations with which our products are not compatible, our existing products would become less desirable to our customers and our revenue and results of operations would suffer.
The results of our operations could be adversely affected by economic and political conditions and the effects of these conditions on our customers’ businesses and levels of business activity.
Global economic and political conditions affect our customers’ businesses and the markets they serve. A severe or prolonged economic downturn, including during and following the COVID-19 pandemic, or a negative or uncertain political climate could adversely affect our customers’ financial conditions and the timing or levels of business activity of our customers and the industries we serve. This may reduce the demand for our products or depress pricing for our products and have a material adverse effect on our results of operations. Changes in global economic conditions could also shift demand to products or services for which we do not have competitive advantages, and this could negatively affect the amount of business we are able to obtain. In addition, if we are unable to successfully anticipate changing economic and political conditions, we may be unable to effectively plan for and respond to those changes, and our business could be negatively affected as a result.
We have experienced net losses in the past, and because our strategy for expansion may be costly to implement, we may experience losses and may not maintain profitability or positive cash flow.
We have experienced net losses in the past. We expect to continue to incur significant expenses as we pursue our strategic initiatives, including increased expenses for research and development, sales and marketing and manufacturing. We may also grow our business in part through acquisitions of additional companies and complementary technologies which could cause us to incur greater than anticipated transaction expenses, amortization or write-offs of intangible assets and other acquisition-related expenses. As a result, we may incur net losses in the future, and these losses could be substantial. At a certain level, continued net losses could impair our ability to comply with Nasdaq continued listing standards, as described further below.
Our ability to generate additional revenues and remain profitable will depend on our ability to execute our key growth initiative regarding the development, marketing and sale of sensing products, develop and commercialize innovative technologies, expand our contract research capabilities and sell the products that result from those development initiatives. We may not be able to sustain or increase our profitability on a quarterly or annual basis.
We have obtained capital by borrowing money under a term loan and revolving line of credit and we might require additional capital to support and expand our business; our term loan and revolving line of credit have various covenants with which we must comply.
We intend to continue to make investments to support our business growth, including developing new products, enhancing our existing products, obtaining important regulatory approvals, enhancing our operating infrastructure, completing our development activities and building our commercial scale manufacturing facilities. To the extent that we are unable to remain profitable and to finance our activities from continuing operations, we may require additional funds to support these initiatives and to grow our business.
If we are successful in raising additional funds through issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, including as the result of the issuance of warrants in connection with the financing, and any new equity securities we issue could have rights, preferences and privileges superior to those of our existing common stock. Furthermore, such financings may jeopardize our ability to apply for SBIR grants or qualify for SBIR contracts or grants, and our dependence on SBIR grants may restrict our ability to raise additional outside capital. If we raise additional funds through debt financings, these financings may involve significant cash payment obligations and covenants that restrict our ability to operate our business and make distributions to our stockholders.
We have a term loan and borrowings under a revolving line of credit with PNC Bank, National Association ("PNC"), which require us to comply with a number of affirmative and restrictive covenants including, among others, financial covenants regarding minimum net leverage and fixed charge coverage, affirmative covenants regarding delivery of financial statements, payment of taxes, and maintenance of government compliance, and restrictive covenants regarding dispositions of property, acquisitions, incurrence of additional indebtedness or liens, investments and transactions with affiliates. We are also restricted from paying dividends or making other distributions or payments on our capital stock, subject to limited exceptions. Upon the occurrence of certain events, including our failure to satisfy its payment obligations, failure to adhere to the financial covenants, the breach of certain of our other covenants, cross defaults to other indebtedness or material agreements, judgment defaults and defaults related to failure to maintain governmental approvals, PNC will have the right, among other remedies, to declare all principal and interest immediately due and payable, and to exercise secured party remedies.
If we are unable to obtain adequate financing or financing terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited.
We face and will face substantial competition in several different markets that may adversely affect our results of operations.
We face and will face substantial competition from a variety of companies in several different markets. As we focus on developing marketing and selling fiber optic sensing products, we may also face substantial and entrenched competition in that market.
Many of our competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than we do. These competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements. In addition, current and potential competitors have established or may establish financial or strategic relationships among themselves or with existing or potential customers or other third parties. Accordingly, new competitors or alliances among competitors could emerge and rapidly acquire significant market share. We cannot assure you that we will be able to compete successfully against current or new competitors, in which case our revenues may fail to increase or may decline.
Intense competition in our markets could result in aggressive business tactics by our competitors, including aggressively pricing their products or selling older inventory at a discount. If our current or future competitors utilize aggressive business tactics, including those described above, demand for our products could decline, we could experience delays or cancellations of customer orders, or we could be required to reduce our sales prices.
Shifts in product mix may result in declines in gross profit.
Our gross profit margins vary among our product platforms and are generally highest on our test and measurement instruments. Our overall gross profit may fluctuate from period to period as a result of a variety of factors including shifts in product mix, the introduction of new products, and decreases in average selling prices for older products. If our customers decide to buy more of our products with low gross profit margins or fewer of our products with high gross profit margins, our total gross profits could be harmed.
RISKS RELATING TO OUR OPERATIONS AND BUSINESS STRATEGY
If we fail to properly evaluate and execute our strategic initiatives, including the integration of acquired businesses, it could have an adverse effect on our future results and the market price of our common stock.
We evaluate strategic opportunities related to products, technology and business transactions, including acquisitions and divestitures. In the past, we have acquired businesses to support our growth strategy, including the acquisition of OptaSense in December 2020, General Photonics Corporation in March 2019 and Micron Optics, Inc. in October 2018. If we choose to enter into such transactions in the future, we face certain risks including:
•the failure of the acquired business to meet our performance and financial expectations;
•difficulty integrating an acquired business's operations, personnel and financial and reporting systems into our current business
•potential unknown liabilities associated with the acquisition;
•lost sales and customers as a result of customers deciding not to do business with us;
•complexities associated with managing the larger combined company with distant business locations;
•integrating personnel while maintaining focus on providing consistent, high quality products;
•loss of key employees; and
•performance shortfalls as a result of the division of management's attention caused by completing the acquisition and integrating operations.
If any of these events were to occur, our ability to maintain relationships with the customers, suppliers and employees or our ability to achieve the anticipated benefits of the acquisition could be adversely affected, or could reduce our future earnings or otherwise adversely affect our business and financial results and, as a result, adversely affect the market price of our common stock.
If we cannot successfully transition our revenue mix from contract research revenues to product sales and license revenues, we may not be able to fully execute our business model or grow our business.
Our business model and future growth depend on our ability to transition to a revenue mix that contains significantly larger product sales and revenues from the provision of services or from licensing. Product sales and these revenues potentially offer greater scalability than contract research revenues. Our current plan is to increase our sales of commercial products, our licensing revenues and our provision of non-research services to customers so as to represent a larger percentage of our total revenues. If we are unable to develop and grow our product sales and revenues from the provision of services or from licensing to augment our contract research revenues, however, our ability to execute our business model or grow our business could suffer. There can be no assurance that we will be able to achieve increased revenues in this manner.
Failure to develop, introduce and sell new products or failure to develop and implement new technologies, could adversely impact our financial results.
Our success will depend on our ability to develop and introduce new products that customers choose to buy. The new products the market requires tend to be increasingly complex, incorporating more functions and operating at faster speeds than old products. If we fail to introduce new product designs or technologies in a timely manner or if customers do not successfully introduce new systems or products incorporating our products, our business, financial condition and results of operations could be materially harmed.
If we are unable to manage growth effectively, our revenues and net loss could be adversely affected.
We may need to expand our personnel resources to grow our business effectively. We believe that sustained growth at a higher rate will place a strain on our management as well as on our other human resources. To manage this growth, we must continue to attract and retain qualified management, professional, scientific and technical and operating personnel. If we are unable to recruit a sufficient number of qualified personnel, we may be unable to staff and manage projects adequately, which in turn may slow the rate of growth of our contract research revenues or our product development efforts.
We may not be successful in identifying market needs for new technologies or in developing new products.
Part of our business model depends on our ability to correctly identify market needs for new technologies. We intend to identify new market needs, but we may not always have success in doing so in part because our contract research largely centers on identification and development of unproven technologies, often for new or emerging markets. Furthermore, we must identify the most promising technologies from a sizable pool of projects. If our commercialization strategy process fails to identify projects with commercial potential or if management does not ensure that such projects advance to the commercialization stage, we may not successfully commercialize new products and grow our revenues.
Our growth strategy requires that we also develop successful commercial products to address market needs. We face several challenges in developing successful new products. Many of our existing products and those currently under development are technologically innovative and require significant and lengthy product development efforts. These efforts include planning, designing, developing and testing at the technological, product and manufacturing-process levels. These activities require us to make significant investments. Although there are many potential applications for our technologies, our resource constraints require us to focus on specific products and to forgo other opportunities. We expect that one or more of the potential products we choose to develop will not be technologically feasible or will not achieve commercial acceptance, and we cannot predict which, if any, of our products we will successfully develop or commercialize. The technologies we research and develop are new and steadily changing and advancing. The products that are derived from these technologies may not be applicable or compatible with the state of technology or demands in existing markets. Our existing products and technologies may become uncompetitive or obsolete if our competitors adapt more quickly than we do to new technologies and changes in customers’ requirements. Furthermore, we may not be able to identify if and when new markets will open for our products given that future applications of any given product may not be readily determinable, and we cannot reasonably estimate the size of any markets that may develop. If we are not able to successfully develop new products, we may be unable to increase our product revenues.
We face risks associated with our international business.
We currently conduct business internationally and we might considerably expand our international activities in the future. Our international business operations are subject to a variety of risks associated with conducting business internationally, including:
•having to comply with U.S. export control regulations and policies that restrict our ability to communicate with non-U.S. employees and supply foreign affiliates and customers;
•changes in or interpretations of foreign regulations that may adversely affect our ability to sell our products, perform services or repatriate profits to the United States;
•the imposition of tariffs;
•hyperinflation or economic or political instability in foreign countries;
•imposition of limitations on, or increase of withholding and other taxes on remittances and other payments by foreign subsidiaries or joint ventures;
•conducting business in places where business practices and customs are unfamiliar and unknown;
•the imposition of restrictive trade policies;
•the imposition of inconsistent laws or regulations;
•the imposition or increase of investment and other restrictions or requirements by foreign governments;
•uncertainties relating to foreign laws and legal proceedings;
•having to comply with a variety of U.S. laws, including the Foreign Corrupt Practices Act ("FCPA"); and
•having to comply with licensing requirements.
We do not know the impact that these regulatory, geopolitical and other factors may have on our international business in the future. Further, the COVID-19 pandemic has prompted precautionary government-imposed closures of certain travel and business. It is unknown whether and how global supply chains, may be affected if such an epidemic persists for an extended period of time. We may incur expenses or delays relating to such events outside of our control or experience potential disruption of our ability to travel to customer sites and industry conferences important to the marketing and support of our products, any of which could have an adverse impact on our business, operating results and financial condition.
We may dispose of or discontinue existing product lines and technology developments, which may adversely impact our future results.
On an ongoing basis, we evaluate our various product offerings and technology developments in order to determine whether any should be discontinued or, to the extent possible, divested. In addition, if we are unable to generate the amount of cash needed to fund the future operations of our business, we may be forced to sell one or more of our product lines or technology developments.
We cannot guarantee that we have correctly forecasted, or that we will correctly forecast in the future, the right product lines and technology developments to dispose or discontinue or that our decision to dispose of or discontinue various investments, product lines and technology developments is prudent if market conditions change. In addition, there are no assurances that the discontinuance of various product lines will reduce operating expenses or will not cause us to incur material charges associated with such decision. Furthermore, the discontinuance of existing product lines entails various risks, including the risk that we will not be able to find a purchaser for a product line or the purchase price obtained will not be equal to at least the book value of the net assets for the product line. Other risks include managing the expectations of, and maintaining good relations with, our historical customers who previously purchased products from a disposed or discontinued product line, which could prevent us from selling other products to them in the future. We may also incur other significant liabilities and costs associated with disposal or discontinuance of product lines, including employee severance costs and excess facilities costs.
Health epidemics, including the COVID-19 pandemic, have had, and could in the future have, an adverse impact on our business, operations, and the markets and communities in which we and our customers and suppliers operate.
In December 2019, a disease referred to as COVID-19 was reported and has spread to many countries worldwide, including the United States.
The ongoing global COVID-19 pandemic has impacted, and will likely continue to impact, the way we conduct our business, including the way in which we interface with customers, suppliers and our employees. Although to date we have not experienced any material changes in our customers’ purchasing patterns during the COVID-19 pandemic, it is possible that the pandemic could result in customers delaying purchasing decisions, deferring the ordering of our products or experiencing reductions in capital expenditure budgets that could otherwise impact the near term demand for our products. Similarly, while we have not experienced any material changes in our supply chain, it is possible that suppliers could experience difficulty in
providing us with necessary components for our products. If the demand for our products, or our access to critical components were to be interrupted, it could have a material adverse impact on our results of operations.
The COVID-19 pandemic has been declared a national emergency. In response to the COVID-19 pandemic, many state, local, and foreign governments have put in place, and others in the future may put in place, quarantines, executive orders, shelter-in-place orders, and similar government orders and restrictions in order to control the spread of the disease. Such orders or restrictions, or the perception that such orders or restrictions could occur, have resulted in business closures, work stoppages, slowdowns and delays, work-from-home policies, travel restrictions, and cancellation or postponement of events, among other effects that could negatively impact productivity and disrupt our operations and those of our customers and suppliers. We have implemented alternate work arrangements, including staggered schedules and shifts, distancing within our offices and working from home for most of our employees, and we may take further actions that alter our operations as may be required by federal, state, or local authorities, or which we determine are in our best interests. While most of our operations can be performed under these alternate work arrangements, there is no guarantee that we will be as effective while working under them because our team is dispersed, many employees may have additional personal needs to attend to (such as looking after children as a result of school closures or family who become sick), and employees may become sick themselves and be unable to work. Decreased effectiveness of our team could adversely affect our results due to our inability to meet in person with potential customers, longer time periods for supply, longer time periods for manufacturing and other decreases in productivity that could seriously harm our business. Furthermore, we may decide to postpone or cancel planned investments in our business in response to changes in our business as a result of the spread of COVID-19, which could seriously harm our business.
In addition, while the potential impact and duration of the COVID-19 pandemic on the global economy and our business in particular may be difficult to assess or predict, the pandemic has resulted in, and may continue to result in, significant disruption of global financial markets, reducing our ability to access capital, which could negatively affect our liquidity in the future.
The global impact of COVID-19 continues to rapidly evolve, and we will continue to monitor the situation closely. The ultimate impact of the COVID-19 pandemic or a similar health epidemic is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, operations, or the global economy as a whole. While the spread of COVID-19 may eventually be contained or mitigated, there is no guarantee that a future outbreak of this or any other widespread epidemics will not occur, or that the global economy will recover, either of which could seriously harm our business.
RISKS RELATING TO OUR REGULATORY ENVIRONMENT
Our operations are subject to domestic and foreign laws, regulations and restrictions, and noncompliance with these laws, regulations and restrictions could expose us to fines, penalties, suspension or debarment, which could have a material adverse effect on our profitability and overall financial position.
Our operations, particularly our international sales, subject us to numerous U.S. and foreign laws and regulations, including, without limitation, regulations relating to imports, exports (including the Export Administration Regulations and the International Traffic in Arms Regulations), technology transfer restrictions, anti-boycott provisions, economic sanctions and anti-corruption laws including the FCPA and the UK Bribery Act of 2010 in the United Kingdom. The number of our various emerging technologies, the development of many of which has been funded by the Department of Defense, presents us with many regulatory challenges. Failure by us or our sales representatives or consultants to comply with these laws and regulations could result in administrative, civil, or criminal liabilities and could result in suspension of our export privileges, which could have a material adverse effect on our business. Changes in regulation or political environment may affect our ability to conduct business in foreign markets including investment, procurement and repatriation of earnings.
Environmental regulations could increase operating costs and additional capital expenditures and delay or interrupt operations.
The photonics industry, as well as the semiconductor industry, are subject to governmental regulations for the protection of the environment, including those relating to air and water quality, solid and hazardous waste handling, and the promotion of occupational safety. Various federal, state and local laws and regulations require that we maintain certain environmental permits. While we believe that we have obtained all necessary environmental permits required to conduct our manufacturing processes, if we are found to be in violation of these laws, we could be subject to governmental fines and liability for damages resulting from such violations.
Changes in the aforementioned laws and regulations or the enactment of new laws, regulations or policies could require increases in operating costs and additional capital expenditures and could possibly entail delays or interruptions of our operations.
If our manufacturing facilities do not meet Federal, state or foreign country manufacturing standards, we may be required to temporarily cease all or part of our manufacturing operations, which would result in product delivery delays and negatively impact revenues.
Our manufacturing facilities are subject to periodic inspection by regulatory authorities and our operations will continue to be regulated by the FDA for compliance with Good Manufacturing Practice requirements contained in the quality systems regulations. We are also required to comply with International Organization for Standardization ("ISO"), quality system standards in order to produce certain of our products for sale in Europe. If we fail to continue to comply with Good Manufacturing Practice requirements or ISO standards, we may be required to cease all or part of our operations until we comply with these regulations. Obtaining and maintaining such compliance is difficult and costly. We cannot be certain that our facilities will be found to comply with Good Manufacturing Practice requirements or ISO standards in future inspections and audits by regulatory authorities. In addition, if we cannot maintain or establish manufacturing facilities or operations that comply with such standards or do not meet the expectations of our customers, we may not be able to realize certain economic opportunities in our current or future supply arrangements.
We are subject to additional significant foreign and domestic government regulations, including environmental and health and safety regulations, and failure to comply with these regulations could harm our business.
Our facilities and current and proposed activities involve the use of a broad range of materials that are considered hazardous under applicable laws and regulations. Accordingly, we are subject to a number of foreign, federal, state and local laws and regulations relating to health and safety, protection of the environment and the storage, use, disposal of, and exposure to, hazardous materials and wastes. We could incur costs, fines and civil and criminal penalties, personal injury and third-party property damage claims, or could be required to incur substantial investigation or remediation costs, if we were to violate or become liable under environmental, health and safety laws. Moreover, a failure to comply with environmental laws could result in fines and the revocation of environmental permits, which could prevent us from conducting our business. Liability under environmental laws can be joint and several and without regard to fault. There can be no assurance that violations of environmental and health and safety laws will not occur in the future as a result of the inability to obtain permits, human error, equipment failure or other causes. Environmental laws could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business. Accordingly, violations of present and future environmental laws could restrict our ability to expand facilities, pursue certain technologies, and could require us to acquire costly equipment or incur potentially significant costs to comply with environmental regulations.
Compliance with foreign, federal, state and local environmental laws and regulations represents a small part of our present budget. If we fail to comply with any such laws or regulations, however, a government entity may levy a fine on us or require us to take costly measures to ensure compliance. Any such fine or expenditure may adversely affect our development. We cannot predict the extent to which future legislation and regulation could cause us to incur additional operating expenses, capital expenditures or restrictions and delays in the development of our products and properties.
We are or may become subject to a variety of privacy and data security laws, and our failure to comply with them could harm our business.
We maintain sensitive information, including confidential business and personal information in connection with our business customers and our employees, and may be subject to laws and regulations governing the privacy and security of such information. In the United States, there are numerous federal and state privacy and data security laws and regulations governing the collection, use, disclosure and protection of personal information. Each of these constantly evolving laws can be subject to varying interpretations.
In addition, states are constantly adopting new laws or amending existing laws, requiring attention to frequently changing regulatory requirements. For example, the California Consumer Privacy Act, or the CCPA, took effect on January 1, 2020 and has been dubbed the first “GDPR-like” law in the United States. The CCPA gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used by requiring covered companies to provide new disclosures to California consumers (as that term is broadly defined and can include any of our current or future employees who may be California residents) and provide such residents new ways to opt-out of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. The CCPA
may increase our compliance costs and potential liability. Some observers have noted that the CCPA could mark the beginning of a trend toward more stringent privacy legislation in the United States. Other states are beginning to pass similar laws.
Additionally, California voters approved a new privacy law, the California Privacy Rights Act, or CPRA, in the November 3, 2020 election. Effective starting on January 1, 2023, the CPRA will significantly modify the CCPA, including by expanding consumers’ rights with respect to certain sensitive personal information. The CPRA also creates a new state agency that will be vested with authority to implement and enforce the CCPA and the CPRA.
New legislation proposed or enacted in Illinois, Massachusetts, Nevada, New Jersey, New York, Rhode Island, Virginia, Washington and other states, and a proposed right to privacy amendment to the Vermont Constitution, imposes, or has the potential to impose, additional obligations on companies that collect, store, use, retain, disclose, transfer and otherwise process confidential, sensitive and personal information, and will continue to shape the data privacy environment nationally. State laws are changing rapidly and there is discussion in Congress of a new federal data protection and privacy law to which we would become subject if it is enacted. All of these evolving compliance and operational requirements impose significant costs that are likely to increase over time, may require us to modify our data processing practices and policies, divert resources from other initiatives and projects, and could restrict the way products and services involving data are offered, all of which could significantly harm our business, financial condition, results of operations and prospects. Further, certain state laws may be more stringent or broader in scope, or offer greater individual rights, with respect to confidential, sensitive and personal information than federal, international or other state laws, and such laws may differ from each other, which may complicate compliance efforts.
A similar situation exists in the EU, where the General Data Protection Regulation, the GDPR, took effect in 2018 in the European Economic Area, the EEA. The GDPR governs the collection, use, disclosure, transfer or other processing of personal data of European data subjects. Among other things, the GDPR imposes requirements regarding the security of personal data and notification of data processing obligations to the competent national data processing authorities, changes the lawful bases on which personal data can be processed, and expands the definition of personal data. In addition, the GDPR increases the scrutiny of transfers of personal data from the EEA to the United States and other jurisdictions that the European Commission does not recognize as having “adequate” data protection laws, and imposes substantial fines for breaches and violations (up to the greater of €20 million or 4% of our consolidated annual worldwide gross revenue). The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies and obtain compensation for damages resulting from violations of the GDPR. Compliance with these and any other applicable privacy and data security laws and regulations is a rigorous and time-intensive process, and we may be required to put in place additional mechanisms ensuring compliance with the new data protection rules. If we fail to comply with any such laws or regulations, we may face significant fines and penalties that could adversely affect our business, financial condition and results of operations. Furthermore, the laws are not consistent, and compliance in the event of a widespread data breach could be costly.
More recently, the Court of Justice of the European Union ruled in July 2020 that the Privacy Shield, used by thousands of companies to transfer data between the European Union and United States, was invalid and could no longer be used. In September 2020, Switzerland concluded that the Swiss-U.S. Privacy Shield Framework does not provide an adequate level of protection for data transfers from Switzerland to the United States. Alternative transfer mechanisms may be used, including the standard contractual clauses (“SCCs”), while the authorities interpret the decisions and scope of the invalidated Privacy Shield, but the SCCs have also been called into question in the same ruling that invalidated Privacy Shield. At present, there are few if any viable alternatives to the SCCs, so future developments may necessitate further expenditures on local infrastructure, changes to internal business processes, or may otherwise affect or restrict sales and operations.
Further, the vote in the United Kingdom in favor of exiting the European Union, referred to as Brexit, has complicated data protection regulation in the United Kingdom. In particular, as of January 1,2021, the GDPR has been converted into United Kingdom law and the United Kingdom is now a “third country” under the GDPR. Pursuant to the Trade and Cooperation Agreement, which went into effect on January 1, 2021, the United Kingdom and European Union agreed to a specified period during which the United Kingdom will be treated like a European Union member state in relation to transfers of personal data to the United Kingdom for four months from January 1, 2021. This period may be extended by two further months. Unless the European Commission makes an ‘adequacy finding’ in respect of the United Kingdom before the expiration of such specified period, the United Kingdom will become an ‘inadequate third country’ under the GDPR and transfers of data from the EEA to the United Kingdom will require an ‘transfer mechanism,’ such as the standard contractual clauses. Furthermore, following the expiration of the specified period, there will be increasing scope for divergence in application, interpretation and enforcement of the data protection law as between the United Kingdom and EEA.
In addition to the foregoing, any breach of privacy laws or data security laws, particularly resulting in a significant security incident or breach involving the misappropriation, loss or other unauthorized use or disclosure of sensitive or confidential personal information, could have a material adverse effect on our business, reputation and financial condition. In any circumstances where we are a data controller, we will be accountable for any third-party service providers we engage to
process personal data on our behalf. We attempt to mitigate the associated risks but there is no assurance that privacy and security-related safeguards will protect us from all risks associated with the third-party processing, storage and transmission of such information.
RISKS RELATING TO OUR INTELLECTUAL PROPERTY
Our proprietary rights may not adequately protect our technologies.
Our commercial success will depend in part on our obtaining and maintaining patent, trade secret, copyright and trademark protection of our technologies in the United States and other jurisdictions as well as successfully enforcing this intellectual property and defending it against third-party challenges. We will only be able to protect our technologies from unauthorized use by third parties to the extent that valid and enforceable intellectual property protections, such as patents or trade secrets, cover them. In particular, we place considerable emphasis on obtaining patent and trade secret protection for significant new technologies, products and processes. The degree of future protection of our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. The degree of future protection of our proprietary rights is also uncertain for products that are currently in the early stages of development because we cannot predict which of these products will ultimately reach the commercial market or whether the commercial versions of these products will incorporate proprietary technologies.
Our patent position is highly uncertain and involves complex legal and factual questions. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. For example:
•we or our licensors might not have been the first to make the inventions covered by each of our pending patent applications and issued patents;
•we or our licensors might not have been the first to file patent applications for these inventions;
•others may independently develop similar or alternative technologies or duplicate any of our technologies;
•it is possible that none of our pending patent applications or the pending patent applications of our licensors will result in issued patents;
•patents may issue to third parties that cover how we might practice our technology;
•our issued patents and issued patents of our licensors may not provide a basis for commercially viable technologies, may not provide us with any competitive advantages, or may be challenged and invalidated by third parties; and
•we may not develop additional proprietary technologies that are patentable.
Patents may not be issued for any pending or future pending patent applications owned by or licensed to us, and claims allowed under any issued patent or future issued patent owned or licensed by us may not be valid or sufficiently broad to protect our technologies. Moreover, protection of certain of our intellectual property may be unavailable or limited in the United States or in foreign countries, and we have not sought to obtain foreign patent protection for certain of our products or technologies due to cost, concerns about enforceability or other reasons. Any issued patents owned by or licensed to us now or in the future may be challenged, invalidated, or circumvented, and the rights under such patents may not provide us with competitive advantages. In addition, competitors may design around our technology or develop competing technologies. Intellectual property rights may also be unavailable or limited in some foreign countries, and in the case of certain products no foreign patents were filed or can be filed. This could make it easier for competitors to capture or increase their market share with respect to related technologies. We could incur substantial costs to bring suits in which we may assert our patent rights against others or defend ourselves in suits brought against us. An unfavorable outcome of any litigation could have a material adverse effect on our business and results of operations.
We also rely on trade secrets to protect our technology, especially where we believe patent protection is not appropriate or obtainable. However, trade secrets are difficult to protect. We regularly attempt to obtain confidentiality agreements and contractual provisions with our collaborators, employees and consultants to protect our trade secrets and proprietary know-how. These agreements may be breached or may not have adequate remedies for such breach. While we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors or scientific and other advisors, or those of our strategic partners, may unintentionally or willfully disclose our information to competitors. If we were to enforce a claim that a third party had illegally obtained and was using our trade secrets, our enforcement efforts would be expensive and time consuming, and the outcome would be unpredictable. In addition, courts outside the United States are sometimes unwilling to protect trade secrets. Moreover, if our competitors independently develop equivalent knowledge, methods and know-how, it will be more difficult for us to enforce our rights and our business could be harmed.
If we are not able to defend the patent or trade secret protection position of our technologies, then we will not be able to exclude competitors from developing or marketing competing technologies and we may not generate enough revenues from product sales to justify the cost of developing our technologies and to achieve or maintain profitability.
We also rely on trademarks to establish a market identity for our company and our products. To maintain the value of our trademarks, we might have to file lawsuits against third parties to prevent them from using trademarks confusingly similar to or dilutive of our registered or unregistered trademarks. Also, we might not obtain registrations for our pending trademark applications, and we might have to defend our registered trademark and pending trademark applications from challenge by third parties. Enforcing or defending our registered and unregistered trademarks might result in significant litigation costs and damages, including the inability to continue using certain trademarks.
Third parties may claim that we infringe their intellectual property, and we could suffer significant litigation or licensing expense as a result.
Various U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in our technology areas. Such third parties may claim that we infringe their patents. Because patent applications can take several years to result in a patent issuance, there may be currently pending applications, unknown to us, which may later result in issued patents that our technologies may infringe. For example, we are aware of competitors with patents in technology areas applicable to our optical test equipment products. Such competitors may allege that we infringe these patents. There could also be existing patents of which we are not aware that our technologies may inadvertently infringe. We have from time to time been, and may in the future be, contacted by third parties, including patent assertion entities or intellectual property advisors, about licensing opportunities that also contain claims that we are infringing on third party patent rights. If third parties assert these claims against us, we could incur extremely substantial costs and diversion of management resources in defending these claims, and the defense of these claims could have a material adverse effect on our business, financial condition and results of operations. Even if we believe we have not infringed on a third party’s patent rights, we may have to settle a claim on unfavorable terms because we cannot afford to litigate the claim. In addition, if third parties assert claims against us and we are unsuccessful in defending against these claims, these third parties may be awarded substantial damages as well as injunctive or other equitable relief against us, which could effectively block our ability to make, use, sell, distribute or market our products and services in the United States or abroad.
Commercial application of nanotechnologies in particular, or technologies involving nanomaterials, is new and the scope and breadth of patent protection is uncertain. Consequently, the patent positions of companies involved in nanotechnologies have not been tested, and there are complex legal and factual questions for which important legal principles will be developed or may remain unresolved. In addition, it is not clear whether such patents will be subject to interpretations or legal doctrines that differ from conventional patent law principles. Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our nanotechnology-related intellectual property. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our nanotechnology-related patents or in third party patents. In the event that a claim relating to intellectual property is asserted against us, or third parties not affiliated with us hold pending or issued patents that relate to our products or technology, we may seek licenses to such intellectual property or challenge those patents. However, we may be unable to obtain these licenses on commercially reasonable terms, if at all, and our challenge of the patents may be unsuccessful. Our failure to obtain the necessary licenses or other rights could prevent the sale, manufacture or distribution of our products and, therefore, could have a material adverse effect on our business, financial condition and results of operations.
A substantial portion of our technology is subject to retained rights of our licensors, and we may not be able to prevent the loss of those rights or the grant of similar rights to third parties.
A substantial portion of our technology is licensed from academic institutions, corporations and government agencies. Under these licensing arrangements, a licensor may obtain rights over the technology, including the right to require us to grant a license to one or more third parties selected by the licensor or that we provide licensed technology or material to third parties for non-commercial research. The grant of a license for any of our core technologies to a third party could have a material and adverse effect on our business. In addition, some of our licensors retain certain rights under the licenses, including the right to grant additional licenses to a substantial portion of our core technology to third parties for non-commercial academic and research use. It is difficult to monitor and enforce such non-commercial academic and research uses, and we cannot predict whether the third-party licensees would comply with the use restrictions of such licenses. We have incurred and could incur substantial expenses to enforce our rights against them. We also may not fully control the ability to assert or defend those patents or other intellectual property which we have licensed from other entities, or which we have licensed to other entities.
In addition, some of our licenses with academic institutions give us the right to use certain technology previously developed by researchers at these institutions. In certain cases, we also have the right to practice improvements on the licensed technology to the extent they are encompassed by the licensed patents and are within our field of use. Our licensors may currently own and may in the future obtain additional patents and patent applications that are necessary for the development, manufacture and commercial sale of our anticipated products. We may be unable to agree with one or more academic institutions from which we have obtained licenses whether certain intellectual property developed by researchers at these
academic institutions is covered by our existing licenses. In the event that the new intellectual property is not covered by our existing licenses, we would be required to negotiate a new license agreement. We may not be able to reach agreement with current or future licensors on commercially reasonable terms, if at all, or the terms may not permit us to sell our products at a profit after payment of royalties, which could harm our business.
Some of our patents may cover inventions that were conceived or first reduced to practice under, or in connection with, U.S. government contracts or other federal funding agreements. With respect to inventions conceived or first reduced to practice under a federal funding agreement, the U.S. government may retain a non-exclusive, non-transferable, irrevocable, paid-up license to practice or have practiced for or on behalf of the United States the invention throughout the world. We may not succeed in our efforts to retain title in patents, maintain ownership of intellectual property or in limiting the U.S. government’s rights in our proprietary technologies and intellectual property when an issue exists as to whether such intellectual property was developed in the performance of a federal funding agreement or developed at private expense.
If we fail to obtain the right to use the intellectual property rights of others which are necessary to operate our business, and to protect their intellectual property, our business and results of operations will be adversely affected.
In the past, we have licensed certain technologies for use in our products. In the future, we may choose, or be required, to license technology or intellectual property from third parties in connection with the development of our products. We cannot assure you that third-party licenses will be available on commercially reasonable terms, if at all. Our competitors may be able to obtain licenses, or cross-license their technology, on better terms than we can, which could put us at a competitive disadvantage. Also, we often enter into confidentiality agreements with such third parties in which we agree to protect and maintain their proprietary and confidential information, including at times requiring our employees to enter into agreements protecting such information. There can be no assurance that the confidentiality agreements will not be breached by any of our employees or that such third parties will not make claims that their proprietary information has been disclosed.
RISKS RELATING TO OUR COMMON STOCK
Our common stock price has been volatile and we expect that the price of our common stock will fluctuate substantially in the future, which could cause you to lose all or a substantial part of your investment.
The public trading price for our common stock is volatile and may fluctuate significantly. Since January 1, 2009, our common stock has traded between a high of $12.85 per share and a low of $0.26 per share. Among the factors, many of which we cannot control, that could cause material fluctuations in the market price for our common stock are:
•sales of our common stock by our significant stockholders, or the perception that such sales may occur;
•changes in earnings estimates, investors’ perceptions, recommendations by securities analysts or our failure to achieve analysts’ earnings estimates;
•changes in our status as an entity eligible to receive SBIR contracts and grants;
•quarterly variations in our or our competitors’ results of operations;
•challenges integrating our recent or future acquisitions, including the inability to realize any expected synergies;
•general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors;
•announcements by us, or by our competitors, of acquisitions, new products, significant contracts, commercial relationships or capital commitments;
•pending or threatened litigation;
•any major change in our board of directors or management or any competing proxy solicitations for director nominees;
•changes in governmental regulations or in the status of our regulatory approvals;
•announcements related to patents issued to us or our competitors;
•a lack of, limited or negative industry or securities analyst coverage;
•health epidemics, including the COVID-19 pandemic;
•discussions of our company or our stock price by the financial and scientific press and online investor communities; and
•general developments in our industry.
In addition, the stock prices of many technology companies have experienced wide fluctuations that have often been unrelated to the operating performance of those companies. These factors may materially and adversely affect the market price of our common stock.
If our estimates relating to our critical accounting policies are based on assumptions or judgments that change or prove to be incorrect, our operating results could fall below expectations of financial analysts and investors, resulting in a decline in our stock price.
The preparation of financial statements in conformity with U.S. GAAP requires our management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue and expenses that are not readily apparent from other sources. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of financial analysts and investors, resulting in a decline in our stock price. Significant assumptions and estimates used in preparing our consolidated financial statements include those related to revenue recognition, stock-based compensation and income taxes. Moreover, the revenue recognition guidance, ASC Topic 606, Revenue from Contracts with Customers, requires more judgment than did the prior guidance.
Our financial results may be adversely affected by changes in accounting principles applicable to us.
U.S. GAAP is subject to interpretation by the FASB, the SEC, and other bodies formed to promulgate and interpret appropriate accounting principles. For example, in May 2014, the FASB issued ASC Topic 606, Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. We adopted this guidance as of January 1, 2018. The most significant impact relates to changing the revenue recognition for custom optoelectronics to an over time method. Before the adoption of this standard, we deferred the recognition of revenue until products were shipped to the customer. Any difficulties in implementing these pronouncements or adequately accounting after adoption could cause us to fail to meet our financial reporting obligations, which could result in regulatory discipline and harm investors’ confidence in us.
Anti-takeover provisions in our amended and restated certificate of incorporation and bylaws and Delaware law could discourage or prevent a change in control, even if an acquisition would be beneficial to our stockholders, which could affect our stock price adversely and prevent attempts by our stockholders to replace or remove our current management.
Our amended and restated certificate of incorporation and bylaws and Delaware law contain provisions that might delay or prevent a change in control, discourage bids at a premium over the market price of our common stock and adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock. These provisions include:
•a classified board of directors serving staggered terms;
•advance notice requirements to stockholders for matters to be brought at stockholder meetings;
•a supermajority stockholder vote requirement for amending certain provisions of our amended and restated certificate of incorporation and bylaws; and
•the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer.
We are also subject to provisions of the Delaware General Corporation law that, in general, prohibit any business combination with a beneficial owner of 15% or more of our common stock for three years unless the holder’s acquisition of our stock was approved in advance by our board of directors or certain other conditions are satisfied.
The existence of these provisions could adversely affect the voting power of holders of common stock and limit the price that investors might be willing to pay in the future for shares of our common stock.
GENERAL RISK FACTORS
We could be negatively affected by a security breach or other compromise, either through cyber-attack, cyber-intrusion or other significant disruption of our IT networks and related systems.
We face the risk, as does any company, of a security breach or other compromise, whether through cyber-attack or cyber-intrusion over the internet, malware, computer viruses, attachments to e-mails, persons inside our organization or persons with access to systems inside our organization, or other significant disruption of our IT networks and related systems. The risk of a security breach or disruption, particularly through cyber-attack or cyber-intrusion, including by computer hackers, foreign governments and cyber terrorists, has increased as the number, intensity and sophistication of attempted attacks and intrusions
from around the world have increased. We may also experience security breaches or compromises from unintentional or accidental actions by our employees, contractors, consultants, business partners, and/or other third parties. To the extent that any security breach or disruption were to result in a loss, destruction, unavailability, alteration or dissemination of, or damage to, our data or applications, or for it to be believed or reported that any of these occurred, we could incur liability and reputational damage.
As a technology company, and particularly as a government contractor, we may face a heightened risk of a security breach, compromise or disruption from attempts to gain unauthorized access to our proprietary, confidential or classified information on our IT networks and related systems via cyber-attacks or cyber-intrusions. These types of information and IT networks and related systems are critical to the operation of our business and essential to our ability to perform day-to-day operations, and, in some cases, are critical to our operations or those of our customers. Such critical information includes our proprietary software code, which we protect as a trade secret and is critical to the competitive advantage of many of our products, which could be adversely affected if this code were stolen in a cyber-intrusion or otherwise compromised. In addition, as certain of our technological capabilities become widely known, it is possible that we may be subjected to cyber-attack or cyber-intrusion as third parties seek to gain improper access to information regarding these capabilities and cyber-attacks or cyber-intrusion could compromise our confidential information or our IT networks and systems generally, as it is not practical as a business matter to isolate all of our confidential information and trade secrets from email and internet access. A security breach, compromise or other significant disruption involving these types of information and IT networks and related systems could disrupt the proper functioning of these networks and systems and therefore our operations, compromise our confidential information and trade secrets, or damage our reputation among our customers and the public generally. We have not identified any significant security breaches or experienced other significant disruptions of these types to date. To date, we have not experienced a significant cyber-intrusion, cyber-attack or other similar disruption. There can be no assurance that our security efforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. Any of these developments in the future could have a negative impact on our results of operations, financial condition and cash flows.
If there are substantial sales of our common stock, or the perception that such sales may occur, our stock price could decline.
If any of our stockholders were to sell substantial amounts of our common stock, the market price of our common stock may decline, which might make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. Substantial sales of our common stock, or the perception that such sales may occur, may have a material adverse effect on the prevailing market price of our common stock.
We may become involved in securities class action litigation that could divert management’s attention and harm our business and our insurance coverage may not be sufficient to cover all costs and damages.
The stock market has from time to time experienced significant price and volume fluctuations that have affected the market prices for the common stock of technology companies. These broad market fluctuations may cause the market price of our common stock to decline. In the past, following periods of volatility in the market price of a particular company’s securities, securities class action litigation has often been brought against that company. Securities class litigation also often follows certain significant business transactions, such as the sale of a business division or a change in control transaction. We may become involved in this type of litigation in the future. Litigation often is expensive and diverts management’s attention and resources, which could adversely affect our business.
We are obligated to develop and maintain proper and effective internal controls over financial reporting and any failure to maintain the adequacy of these internal controls may adversely affect investor confidence in our company and, as a result, the value of our common stock.
We are required, pursuant to Section 404 of the Sarbanes-Oxley Act to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting on an annual basis. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting.
During the evaluation and testing process of our internal controls, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. While we have established certain procedures and controls over our financial reporting processes, we cannot assure you that these efforts will prevent restatements of our financial statements in the future. We may not be able to remediate any future material weaknesses, or to complete our evaluation, testing and any required remediation in a timely fashion.
Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition or results of operations. If we are unable to conclude that our internal control over financial reporting is effective, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by the Nasdaq Stock Market, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES
STOCKHOLDERS
Our common stock is listed on the Nasdaq Capital Market under the symbol "LUNA." As of March 10, 2021, we had 31,397,642 shares of common stock outstanding held by 94 holders of record. The actual number of stockholders is greater than this number of record holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.
STOCK PERFORMANCE GRAPH
The graph set forth below compares the cumulative total stockholder return on our common stock for the previous five years, during which our common stock was traded on the Nasdaq Capital Market, as compared to the cumulative total return of the Nasdaq Composite Index and the Russell 2000 Index over the same period. This graph assumes the investment of $100,000 in our common stock at the closing price on January 1, 2016, and an equivalent amount in the Nasdaq Composite Index and the Russell 2000 Index on that date, and assumes the reinvestment of dividends, if any. We have never paid dividends on our common stock and have no present plans to do so.
Since there is no published industry or line-of-business index for our business reflective of our performance, nor do we believe we can reasonably identify a peer group, we measure our performance against issuers with similar market capitalizations. We selected the Russell 2000 Index because it measures the performance of a broad range of companies with lower market capitalizations than those companies included in the S&P 500 Index.
The comparisons shown in the graph below are based upon historical data. We caution that the stock price performance shown in the graph below is not necessarily indicative of, nor is it intended to forecast, the potential future performance of our common stock.
The preceding Stock Performance Graph is not deemed filed with the Securities and Exchange Commission and shall not be incorporated by reference in any of our filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.
DIVIDEND POLICY
Since our inception, we have never declared or paid any cash dividends on our common stock. We currently expect to retain any future earnings for use in the operation and expansion of our business, and therefore do not anticipate paying any cash dividends in the foreseeable future. In addition, our debt facility with PNC Bank restricts us from paying cash dividends on our capital stock without the bank’s prior written consent.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes to those statements included elsewhere in this report. In addition to historical financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those discussed under “Risk Factors” and elsewhere in this report.
Business Overview
We are a leader in advanced optical technology, providing high performance fiber optic test, measurement and control products for the telecommunications and photonics industries; and distributed fiber optic sensing solutions that measure, or “sense,” the structures for industries ranging from aerospace, automotive, energy, oil and gas, security and infrastructure.
Our communications test and control products help customers test their fiber optic networks and assemblies with speed and precision in both lab and production environments, accelerating the development of fiber optic products and assuring accurate testing of optical components like photonic integrated circuits (PICs) and coherent receivers, which are both critical elements of meeting the world’s exponentially growing demand for bandwidth. Our distributed fiber optic sensing products help designers and manufacturers more efficiently develop new and innovative products by measuring stress, strain, and temperature at a high resolution for new designs or manufacturing processes. In addition, our distributed fiber optic sensing products ensure the safety and structural integrity or operational health of critical assets in the field, by monitoring stress, strain, and vibration in large civil and industrial infrastructure such as bridges, roads, pipelines and borders. We also provide applied research services, typically under research programs funded by the U.S. government, in areas of sensing and instrumentation, advanced materials, optical technologies and health sciences.
We are organized into two reporting segments, our Lightwave segment and our Luna Labs segment. Our Lightwave segment consists of our fiber optics testing, measurement and sensing solutions. Our Lightwave segment revenues represented approximately 71% and 70% of our total revenues for the years ended December 31, 2020 and 2019, respectively.
Our Luna Labs segment performs applied research principally in the areas of sensing and instrumentation, advanced materials and health sciences. Our Luna Labs segment comprised approximately 29% and 30% of our total revenues for the years ended December 31, 2020 and 2019, respectively. Most of the government funding for our Luna Labs segment is derived from the Small Business Innovation Research ("SBIR"), program coordinated by the U.S. Small Business Administration. Within the Luna Labs segment, we have historically had a backlog of contracts for which work has been scheduled, but for which a specified portion of work has not yet been completed. We define backlog as the dollar amount of obligations payable to us under negotiated contracts upon completion of a specified portion of work that has not yet been completed, exclusive of revenues previously recognized for work already performed under these contracts, if any. Total backlog includes funded backlog, which is the amount for which money has been directly authorized by the U.S. government and for which a purchase order has been received by a commercial customer, and unfunded backlog, representing firm orders for which funding has not yet been appropriated. Indefinite delivery and quantity contracts and unexercised options are not reported in total backlog. The approximate value of our Lightwave segment backlog was $35.9 million and $16.1 million at December 31, 2020 and 2019, respectively. The approximate value of our Luna Labs segment backlog was $19.0 million and $21.8 million at December 31, 2020 and 2019, respectively.
Revenues from product sales are mostly derived from the sales of our communications test, measurement, control and sensing products that make use of light-transmitting optical fibers, or fiber optics. We continue to invest in product development and commercialization, which we anticipate will lead to increased product sales growth. Although we have been successful in licensing certain technologies in past years, we do not expect license revenues to represent a significant portion of future revenues. Over time we intend to gradually increase such revenues. In the near term, we expect revenues from product sales to continue to be primarily in areas associated with our communications test, measurement, control and sensing fiber optic test platforms. In the long term, we expect that revenues from product sales will represent a larger portion of our total revenues. As we develop and commercialize new products, our revenues will reflect a broader and more diversified mix of products.
We realized net income attributable to common stockholders of approximately $3.3 million for the year ended December 31, 2020 and net income attributable to common stockholders of approximately $5.1 million for the year ended December 31, 2019. We realized net income from continuing operations of $4.7 million for the year ended December 31, 2020 and net income from continuing operations of $5.3 million for the year ended December 31, 2019.
We may incur increasing expenses as we seek to expand our business, including expenses for research and development, sales and marketing and manufacturing capabilities. We may continue to grow our business in part through acquisitions of
additional companies and complementary technologies, which could cause us to incur transaction expenses, amortization or write-offs of intangible assets and goodwill and other acquisition-related expenses. As a result, we may incur net losses in future periods, and these losses could be substantial.
Acquisitions
OptaSense Holdings Limited
On December 3, 2020, we acquired OptaSense Holdings Limited ("OptaSense") for $38.9 million (£29.0 million) in cash. OptaSense, formerly owned by QinetiQ Holdings Limited, is a market leader in fiber optic distributed monitoring solutions for pipelines, oilfield services, security, highways and railways, and in power and utilities monitoring systems. The acquisition of OptaSense provided us with important distributed acoustic sensing ("DAS") intellectual property and products. OptaSense's technology and products and geographic footprint are highly complementary to our Lightwave segment which we believe will accelerate our technology and overall growth roadmap.
General Photonics Corporation
On March 1, 2019, we acquired all of the outstanding stock of General Photonics Corporation ("GP"), a leading provider of innovative components, modules and test equipment focused on the generation, measurement and control of polarized light critical in fiber optic-based applications for aggregate consideration of $20.0 million, inclusive of $19.0 million paid at closing and $1.0 million of contingent consideration in 2020 related to certain earn-out provisions.
Description of Our Revenues, Costs and Expenses
Impact of COVID-19 Pandemic
The broader impact of the COVID-19 pandemic on our results of operations and overall financial performance remains uncertain. The COVID-19 pandemic has affected how we interact with our customers by reducing face-to-face meetings and increasing our on-line and virtual presence. While increasing our on-line and virtual presence has proven effective, we are unsure of the impact if these conditions continue for an extended period. In addition, we have experienced minor impacts on our supply chain that we have managed. For example, in cases where there were delays we relied on our inventory of components to continue production. There is no guarantee we will be able to manage through future delays in our supply chain. See “Risk Factors” for further discussion of the potential adverse impacts of the COVID-19 pandemic on our business.
Revenues
We generate revenues from product sales, commercial product development and licensing and technology development activities. Our Lightwave segment revenues reflect amounts that we receive from sales of our products or development of products for third parties and, to a lesser extent, fees paid to us in connection with licenses or sub-licenses of certain patents and other intellectual property.
We derive Luna Labs segment revenues from providing research and development services to third parties, including government entities, academic institutions and corporations, and from achieving milestones established by some of these contracts. In general, we complete contracted research over periods ranging from six months to three years and recognize these revenues over the life of the contract as costs are incurred.
Cost of Revenues
Cost of revenues associated with Lightwave segment revenues consists of license fees for use of certain technologies, product manufacturing costs including all direct material and direct labor costs, amounts paid to our contract manufacturers, manufacturing, shipping and handling, provisions for product warranties and inventory obsolescence, as well as overhead allocated to each of these activities.
Cost of revenues associated with Luna Labs segment revenues consists of costs associated with performing the related research activities including direct labor, amounts paid to subcontractors and overhead allocated to Luna Labs segment activities.
Operating Expense
Operating expense consists of selling, general and administrative expense, as well as expenses related to research, development and engineering, depreciation of fixed assets and amortization of intangible assets. These expenses also include compensation for employees in executive and operational functions including certain non-cash charges related to expenses from
equity awards, facilities costs, professional fees, salaries, commissions, travel expense and related benefits of personnel engaged in sales, marketing, and administrative activities; costs of marketing programs and promotional materials; salaries, bonuses and related benefits of personnel engaged in our own research and development beyond the scope and activities of our Luna Labs segment; product development activities not provided under contracts with third parties; and overhead costs related to these activities.
Investment Income
Investment income consists of amounts earned on our cash equivalents. We sweep on a daily basis a portion of our cash on hand into a fund invested in U.S. government obligations.
Interest Expense, Net
Interest expense is composed of interest paid under our term loans as well as interest accrued on our finance lease obligations.
Critical Accounting Policies and Estimates
Lightwave Revenues
To determine the proper revenue recognition method for Lightwave contracts, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. We recognize revenue when the performance obligation has been satisfied by transferring the control of the product or service to the customer. For tangible products that contain software that is essential to the tangible product’s functionality, we consider the product and software to be a single performance obligation and recognize revenue accordingly. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation based on their relative stand-alone selling prices. In such circumstances, we use the observable price of goods or services which are sold separately in similar circumstances to similar customers. If these prices are not observable, then we will estimate the stand-alone selling price using information that is reasonably available. For the majority of our standard products and services, price list and discount structures related to customer type are available. For products and services that do not have price list and discount structures, we may use one or more of the following: (i) adjusted market assessment approach, (ii) expected cost plus a margin approach, and (iii) residual approach. The adjusted market approach requires us to evaluate the market in which we sell goods or services and estimate the price that a customer in that market would be willing to pay for those goods or services. The expected cost-plus margin approach requires us to forecast our expected costs of satisfying the performance obligation and then add a reasonable margin for that good or service. The residual approach decreases the total transaction price by the sum of the observable standalone selling prices if either the company sells the same good or services to different customers for a broad range of amounts or the company has not established a price for the good or service and that good or service has not been sold on a standalone basis. Shipping and handling activities primarily occur after a customer obtains control and are considered fulfillment cost rather than separate performance obligations. Similarly, sales and similar taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer are excluded from the measurement of the transaction price.
For standard products, we recognize revenue at a point in time when control passes to the customer. Absent substantial product acceptance clauses, this is based on the shipping terms. For custom products that require engineering and development based on customer requirements, we will recognize revenue over time using the output method for any items shipped and any finished goods or work in process that is produced for balances of open sales orders. For any finished goods or work in process that has been produced for the balance of open sales orders we recognize revenue by applying the average selling price for such open order to the lesser of the on-hand balance in finished goods or open sales order quantity which we present as a contract asset on the balance sheet. Cost of sales is recognized based on the standard cost of the finished goods and work in process associated with this revenue and inventory balances are reduced accordingly. For extended warranties and product rentals, revenue is recognized over time using the output method based on the time elapsed for the warranty or service period. In the case of warranties, we record a contract liability for amounts billed but that are not recognized until subsequent periods. A separate contract liability is recorded for the cost associated with warranty repairs based on our estimate of future expense. For testing services where we are performing testing on an asset the customer controls, revenue is recognized over time by the output method using the performance to date. For training, where the customer is receiving the benefit of training as it is occurring, and for repairs to a customer-controlled asset, revenue is recognized over time by the output method using the
performance to date. For royalty revenue, we apply the practical expedient “royalty exception” recognizing revenue based on the royalty agreement which specifies an amount based on sales or minimum amount, whichever is greater.
In some product rental contracts, a customer may be offered a discount on the purchase of an item that would provide for a material right. When a material right has been provided to a customer, a separate performance obligation is established, and a portion of the rental revenue will be deferred until the future product is purchased or the option expires. This deferred revenue is recognized as a contract liability on the balance sheet.
Luna Labs Revenues
We perform research and development for U.S. Federal government agencies, educational institutions and commercial organizations. We account for a research contract when a contract has been executed, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of the contract price is considered probable. Revenue is earned under cost reimbursable, time and materials and fixed price contracts. Direct contract costs are expensed as incurred.
Our contracts with agencies of the U.S. government are subject to periodic funding by the respective contracting agency. Funding for a contract may be provided in full at inception of the contract or ratably throughout the contract as the services are provided. In evaluating the probability of funding for purposes of assessing collectability of the contract price, we consider our previous experience with our customers, communication with our customers regarding funding status and our knowledge of available funding for the contract or program. If funding is not assessed as probable, revenue recognition is deferred until realization is reasonably assured.
Under the typical payment terms of our U.S. government contracts, the customer pays us either performance-based payments ("PBPs") or progress payments. PBPs, which are typically used in the firm fixed price contracts, are interim payments based on quantifiable measures of performance or on the achievement of specified events or milestones. Progress payments, which are typically used in our cost type contracts, are interim payments based on costs incurred as the work progresses. For our U.S. government cost-type contracts, the customer generally pays us during the performance period for 80%-90% of our actual costs incurred. Because the customer retains a small portion of the contract price until completion of the contract and audit of allowable costs, cost type contracts generally result in revenue recognized in excess of billings which we present as contract assets on the balance sheet. Amounts billed and due from our customers are classified as receivables on the balance sheet. For non-U.S. government contracts, we typically receive interim payments as work progresses, although for some contracts, we may be entitled to receive advance payments. We recognize a liability for these advance payments and PBPs paid in advance which are in excess of the revenue recognized and present these amounts as contract liabilities on the balance sheet.
To determine the proper revenue recognition method for research and development contracts, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. For instances where a contract has options that were bid with the initial contract and awarded at a later date, we combine the options with the original contract when options are awarded. For most of our contracts, the customer contracts for research with multiple milestones that are interdependent. Consequently, the entire contract is accounted for as one performance obligation. The effect of the combined or modified contract on the transaction price and measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.
Contract revenue recognition is measured over time as we perform because of continuous transfer of control to the customer. For U.S. government contracts which are typically subject to the Federal Acquisition Regulation, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay us for cost incurred plus a reasonable profit and take control of any work in process. From time to time, as part of normal management processes, facts may change, causing revisions to estimated total costs or revenues expected. The cumulative impact of any revisions to estimates and the full impact of anticipated losses on any type of contract are recognized in the period in which they become known.
Because of control transfers over time, revenue is recognized over time based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the services to be provided. We generally use the input method, more specifically the cost-to-cost measure of progress for our contracts because it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is
measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The underlying bases for estimating our contract research revenues are measurable expenses, such as labor, subcontractor costs and materials, and data that are updated on a regular basis for purposes of preparing our cost estimates. Our research contracts generally have a period of performance of six months to three years, and our estimates of contract costs have historically been consistent with actual results. Revisions in these estimates between accounting periods to reflect changing facts and circumstances have not had a material impact on our operating results, and we do not expect future changes in these estimates to be material. The cumulative impact of any revisions to estimates and the full impact of anticipated losses on any type of contract are recognized in the period in which they become known.
Under cost reimbursable contracts, we are reimbursed for costs that are determined to be reasonable, allowable and allocable to the contract and paid a fixed fee representing the profit negotiated between us and the contracting agency. Revenue from cost reimbursable contracts is recognized as costs are incurred plus an estimate of applicable fees earned. We consider fixed fees under cost reimbursable contracts to be earned in proportion to the allowable costs incurred in performance of the contract.
Revenue from time and materials contracts is recognized based on direct labor hours expended at contract billing rates plus other billable direct costs.
Fixed price contracts may include either a product delivery or specific service performance throughout a period. For fixed price contracts that are based on the proportional performance method and involve a specified number of deliverables, we recognize revenue based on the proportion of the cost of the deliverables compared to the cost of all deliverables included in the contract as this method more accurately measures performance under these arrangements. For fixed price contracts that provide for the development and delivery of a specific prototype or product, revenue is recognized based upon the percentage of completion method.
Whether certain costs under government contracts are allowable is subject to audit by the government. Certain indirect costs are charged to contracts using provisional or estimated indirect rates, which are subject to later revision based on government audits of those costs. Management is of the opinion that costs subsequently disallowed, if any, would not likely have a significant impact on revenues recognized for those contracts.
Income Taxes
We estimate our tax liability through calculating our current tax liability, together with assessing temporary differences resulting from the different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which we record on our balance sheet. Management then assesses the likelihood that deferred tax assets will be recovered in future periods. In assessing the need for a valuation allowance against the net deferred tax asset, management considers factors such as future reversals of existing taxable temporary differences, taxable income in prior carry back years, whether carry back is permitted under the tax law, tax planning strategies and estimated future taxable income exclusive of reversing temporary differences and carryforwards. To the extent that we cannot conclude that it is more likely than not that the benefit of such assets will be realized, we establish a valuation allowance to reduce their net carrying value.
As we assess our projections of future taxable income or other factors that may impact our ability to generate taxable income in future periods, our estimate of the required valuation allowance may change, which could have a material impact on future earnings or losses.
We recognize tax benefits from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities. While it is often difficult to predict the final outcome of timing of the resolution of any particular tax matter, we establish a liability at the time we determine it is probable we will be required to pay additional taxes related to certain matters. These liabilities are recorded in accrued liabilities in our consolidated balance sheets. We adjust this provision, including any impact on the related interest and penalties, in light of changing facts and circumstances, such as the progress of a tax audit. A number of years may elapse before a particular matter for which we have established a liability is audited and finally resolved. The number of years with open tax audits varies depending on the tax jurisdiction. Settlement of any particular issue would usually require the use of cash. We recognize favorable resolutions of tax matters for which we have previously established liabilities as a reduction to our income tax expense when the amounts involved become known.
Due to differences between federal and state tax law, and accounting principles generally accepted in the United States of America ("GAAP") certain items are included in the tax return at different times than when those items are reflected in the consolidated financial statements. Therefore, the annual tax rate reflected in our consolidated financial statements is different than that reported in our tax return. Some of these differences are permanent, such as expenses that are not deductible in our tax
return. Some differences, such as depreciation expense, reverse over time and create deferred tax assets and liabilities. The tax rates used to determine deferred tax assets or liabilities are the enacted tax rates in effect for the year in which the differences are expected to reverse. Based on the evaluation of all available information, we recognize future tax benefits, such as net operating loss ("NOL") carryforwards, to the extent that realizing these benefits is considered more likely than not.
Because we have NOLs carried over from a previously acquired company that are limited under Section 382, the deferred tax assets of $1.2 million as of December 31, 2020 are expected to be realized over an extended period of time (with continued earnings realized ratably through 2033).
Following our acquisition of OptaSense, the deferred taxes include loss carry forwards in the United Kingdom, and the United States. Given cumulative three years of losses for each of the entities, we have concluded that it is more-likely-than-not that the net deferred tax assets from the UK and US entities will not be realized, and have recorded a full valuation allowance against them.
Stock-Based Compensation
We recognize stock-based compensation expense based upon the fair value of the underlying equity award on the date of the grant. The calculation of the fair value of our awards requires certain inputs that are subjective and changes to the estimates used will cause the fair values of our stock awards and related stock-based compensation expense to vary. We have elected to use the Black-Scholes-Merton ("Black-Scholes") option pricing model to determine the fair value of stock options. The fair value of a stock option award is affected by our stock price on the date of the grant as well as other assumptions used as inputs in the valuation model including the estimated volatility of our stock price over the term of the awards, the estimate period of time that we expect employees to hold their stock options and the risk-free interest rate assumption. In addition, we are required to reduce stock-based compensation expense for the effects of actual forfeitures of unvested awards in the period they occur.
Long-lived and Intangible Assets
Long-lived assets and certain identifiable intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future un-discounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less cost to sell.
Goodwill
Goodwill is reviewed for impairment at least annually, or more frequently if events or circumstances indicate that goodwill might be impaired. We have established October 1 as our specified annual date for impairment testing.
Business Combinations
We account for business combinations under the acquisition method of accounting, in accordance with ASC 805 - Business Combinations. Under ASC 805, the total estimated purchase consideration is allocated to the acquired tangible and intangible assets and assumed liabilities based on their estimated fair values as of the acquisition date. Any excess of the fair value of acquisition consideration over the fair value of identifiable assets acquired and liabilities assumed is recorded as goodwill.

Lightwave revenues $ 59,115 $ 49,117 $ 9,998 20.4 %
Luna Labs revenues 23,566 21,399 2,167 10.1 %
Total revenues $ 82,681 $ 70,516 $ 12,165 17.3 %
Our Lightwave segment included revenues from sales of test and measurement systems, primarily representing sales of our Optical Backscatter Reflectometer, ODiSI, and Optical Vector Analyzer platforms, optical components and sub-assemblies and sales of our Hyperion and Terahertz sensing platforms. Our Lightwave segment revenues increased $10.0 million to $59.1 million for the year ended December 31, 2020 compared to $49.1 million for the year ended December 31, 2019. The increase resulted primarily from the incremental revenues associated with the acquired operations of GP and OptaSense as well as increased revenues from our sensing products during the year ended December 31, 2020. Continued growth in sales of our fiber-optic sensing products, including our ODiSI products directed toward the expanding use of composite materials and the need for improved means of testing their structural integrity, and our communications test instruments also contributed to this increase.
Our Luna Labs segment revenues increased $2.2 million to $23.6 million for the year ended December 31, 2020 compared to $21.4 million for the year ended December 31, 2019. Revenues within this segment increased due to additional contract awards, including higher value Phase 2 SBIR contracts. The increase continues a growth trend experienced over the past few years largely driven by successes in Phase 2 SBIR awards. The increase was realized primarily in our advanced materials research group. As Phase 2 SBIR contracts generally have a performance period of a year or more, we currently expect Luna Labs segment revenues to remain at a similar level for the near term.
Cost of Revenues
Years ended December 31,
(in thousands) 2020 2019 $ Difference % Difference
Lightwave costs $ 23,306 $ 20,157 $ 3,149 15.6 %
Luna Labs costs 17,187 15,176 2,011 13.3 %
Total costs of revenues $ 40,493 $ 35,333 $ 5,160 14.6 %
Our Lightwave segment costs increased $3.1 million to $23.3 million for the year ended December 31, 2020 compared to $20.2 million for the year ended December 31, 2019. This increase primarily resulted from the incremental costs associated with the inclusion of approximately one month of operations from OptaSense, which was acquired in December 2020, as well as an increase in sales volume in our sensing and communications testing products.
Our Luna Labs segment costs increased $2.0 million, to $17.2 million for the year ended December 31, 2020 compared to $15.2 million for the year ended December 31, 2019. The overall increase in Luna Labs segment costs was driven by increases in additional headcount and the increased spending on other direct costs to support the growth in our research contracts and was consistent with the rate of revenue growth for this business segment.
Operating Expense
Years ended December 31,
(in thousands) 2020 2019 $ Difference % Difference
Selling, general and administrative expense $ 27,644 $ 23,344 $ 4,300 18.4 %
Research, development and engineering expense 6,713 7,496 (783) (10.4) %
Acquisition related expense 2,204 1,027 1,177 114.6 %
Loss on sale of property and equipment 644 - 644 100.0 %
Total operating expense $ 37,205 $ 31,867 $ 5,338 16.8 %
Selling, general and administrative expense increased $4.3 million to $27.6 million for the year ended December 31, 2020 compared to $23.3 million for the year ended December 31, 2019. Selling, general and administrative expense increased primarily due to the additional selling related expenses as a result of increased revenues, increased depreciation on acquired fixed assets and share-based compensation related to employee participation in our ESPP which began during the third quarter.
Research, development and engineering expenses decreased $0.8 million to $6.7 million for the year ended December 31, 2020 compared to $7.5 million for the year ended December 31, 2019 primarily due to additional expenses related to product improvements in our Lightwave segment for the year ended December 31, 2019 that did not reoccur during the year ended December 31, 2020.
Acquisition related expense consists primarily of investment banking, legal and consulting fees incurred in connection with our acquisition of OptaSense for the year ended December 31, 2020. Acquisition related expense for the year ended December 31, 2019 consists of fees incurred in connection with our acquisition of GP.
The loss on sale of property and equipment was primarily due to the sale of one of our buildings and other fixed assets in order to consolidate operations in our Luna Labs operating segment.
Investment Income
Investment income was $0.1 million for the year ended December 31, 2020, compared to $0.4 million for the year ended December 31, 2019. During the years ended December 31, 2020 and 2019, we invested a portion of our cash in funds holding U.S. treasury securities. The decrease in investment income is primarily related to lower returns on our cash balance held in U.S. treasury securities.
Income Tax Expense/(Benefit)
For the year ended December 31, 2020, we recorded income tax expense of $0.3 million, compared to an income tax benefit of $1.7 million for the year ended December 31, 2019. The income tax expense recognized for the year ended December 31, 2020 was driven mostly by not having the benefit of a partial release of our valuation allowance partially offset by research and development tax credits received in 2020.
Net Income From Continuing Operations
For the year ended December 31, 2020, we recognized income from continuing operations before income taxes of $5.1 million, compared to $3.7 million for the year ended December 31, 2019. After tax, our net income from continuing operations was $4.7 million for the year ended December 31, 2020, compared to $5.3 million for the year ended December 31, 2019.
Net Loss from Discontinued Operations
For the year ended December 31,2020, we recognized loss from discontinued operations, net of income taxes, of $1.4 million which represented the after-tax loss on sale of our High Speed Optical Receiver ("HSOR") business. In March 2020, we settled the notice of claim dispute with Macom Technology Solutions, Inc. ("Macom") resulting in us receiving $0.6 million and Macom receiving $1.9 million. There were no results from discontinued operations for the year ended December 31, 2019.
Preferred Stock Dividend
In January 2010, we issued 1,321,514 shares of our newly designated Series A Convertible Preferred Stock to Carilion. The Series A Convertible Preferred Stock carried an annual cumulative dividend of 6%, or approximately 79,292 shares of common stock per year. During 2019, we accrued $0.3 million for the dividends payable to Carilion. During 2019, the total accrued dividend of 770,454 shares of common stock were issued to Carilion as shown on our consolidated statements of changes in stockholders' equity. There were no additional shares of common stock accrued or issued during 2020.
Liquidity and Capital Resources
At December 31, 2020, our total cash and cash equivalents were $15.4 million.
On December 1, 2020 (the “Effective Date”), we entered into a Loan Agreement (the “Loan Agreement”) with PNC Bank, National Association, as lender (the “Lender”) and our domestic subsidiaries as guarantors. The Loan Agreement provides a $12.5 million term loan facility (the “Term Loan”) and a $15.0 million revolving credit facility (the “Revolving Line”), which include a $3.0 million letter of credit sublimit. On the Effective Date, we borrowed the full amount of the Term Loan from the Lender pursuant to a term note (the “Term Note”) and a $7.6 million revolving loan (the “Revolving Loan”) pursuant to a revolving line of credit note (the “Revolving Line of Credit Note”). We may repay and reborrow advances under the Revolving Line from time to time pursuant to the Revolving Line of Credit Note.
We used the proceeds from the Term Loan and the Revolving Loan to pay, in part, the consideration for the acquisition of OptaSense.
The Term Loan matures on December 1, 2023. The Term Loan is due and payable in 12 equal quarterly payments of principal and interest. The Term Loan bears interest at a floating per annum rate equal to the sum of (a) LIBOR plus (b) a margin ranging from 1.75% to 2.25% depending on the Net Leverage Ratio (as defined in the Loan Agreement). We may prepay the Term Loan without penalty or premium.
The Revolving Line expires on December 1, 2023. Borrowings under the Revolving Line will bear interest at a floating per annum rate equal to the sum of (a) LIBOR plus (b) a margin ranging from 1.75% to 2.25% depending on the Net Leverage Ratio. Accrued interest will be due and payable on the first day of each month and the outstanding principal balance and any accrued but unpaid interest will be due and payable on December 1, 2023. The unused portion of the Revolving Line will accrue a fee equal to 0.20% per annum multiplied by the quarterly average unused amount.
The Loan Agreement includes a number of affirmative and restrictive covenants, including, among others, financial covenants regarding minimum net leverage and fixed charge coverage, affirmative covenants regarding delivery of financial statements, payment of taxes, and maintenance of government compliance, and restrictive covenants regarding dispositions of property, acquisitions, incurrence of additional indebtedness or liens, investments and transactions with affiliates. We are also restricted from paying dividends or making other distributions or payments on our capital stock, subject to limited exceptions. Our obligations under the Loan Agreement are secured by a first priority perfected security interest in substantially all of our and the guarantors’ assets.
Upon the occurrence of certain events, including our failure to satisfy its payment obligations under the Loan Agreement, failure to adhere to the financial covenants, the breach of certain of its other covenants under the Loan Agreement, cross defaults to other indebtedness or material agreements, judgment defaults and defaults related to failure to maintain governmental approvals, the Lender will have the right, among other remedies, to declare all principal and interest immediately due and payable, and to exercise secured party remedies.
We believe that our cash and cash equivalents as of December 31, 2020 in addition to amounts available to us under our Revolving Line will provide adequate liquidity for us to meet our working capital needs over the next twelve months from the date of issuance of the consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Additionally, we believe that should we have the need for increased capital spending to support our planned growth, we will be able to fund such growth through either third-party financing on competitive market terms or through our available cash. However, these estimates are based on assumptions that may prove to be incorrect, including as a result of the ongoing COVID-19 pandemic and its potential impacts on our business. If we require additional capital beyond our current balances of cash and cash equivalents and borrowing capacity under the Revolving Line described above, this additional capital may not be available when needed, on reasonable terms, or at all. Moreover, our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to and volatility in the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic.

Net decrease in cash and cash equivalents $ (9,654) $ (17,454)
During 2020, the $2.9 million of net cash provided by operating activities consisted of our net income of $3.3 million, and included non-cash charges for depreciation and amortization of $3.0 million, and stock-based compensation of $2.1 million, net loss on sale of fixed assets of $0.6 million, and a net loss from discontinued operations of $1.4 million offset by a net cash outflow of $7.2 million from changes in working capital. The changes in working capital were principally driven by an increase in accounts receivable of $3.3 million, an increase in inventory of $1.5 million, an increase in contract assets of $1.5 million, an increase in other assets of $2.2 million, and an increase in accounts payable and accrued expenses of $1.1 million.
In 2019, the $4.8 million of net cash provided by operating activities consisted of our net income of $5.3 million and included non-cash charges for depreciation and amortization of $2.5 million and stock-based compensation of $1.5 million, offset by a net cash outflow of $1.8 million from changes in working capital. The changes in working capital were principally driven by an increase in inventory of $0.7 million, an increase in accounts receivable of $2.2 million, an increase in contract assets of $0.4 million, and an increase in accounts payable and accrued liabilities of $0.6 million, all partially offset by a $0.2 million decrease in other assets.
Cash used in investing activities in 2020 consisted primarily of the $34.1 million payment for acquisitions, $0.7 million of fixed asset additions and $0.4 million of capitalized intellectual property costs partially offset by $0.4 million from the proceeds from the sale of property and equipment and $0.6 million from the sale of discontinued operations, net of fees.
Cash used in the investing activities in 2019 consisted primarily of $19.0 million for our acquisition of GP, $0.5 million of fixed asset additions and $0.3 million of capitalized intellectual property costs.
Cash provided by financing activities for the year ended December 31, 2020 was $21.6 million, compared to $2.4 million of cash used in financing activities in 2019. During 2020, we received proceeds of $20.0 million from our term loan and revolving loan, received $1.7 million from exercises of stock options and received $0.5 million from purchases pursuant to our employee stock purchase plan. These payments were partially offset by $0.5 million to repurchase our common stock under our stock repurchase program. During 2019, we repaid $0.6 million on our outstanding term loan with SVB and used $2.2 million to repurchase our common stock under our stock repurchase program. These payments were partially offset by $0.4 million received from exercises of stock options and warrants.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. We do not hold or issue financial instruments for trading purposes or have any derivative financial instruments. Our exposure to market risk is limited to interest rate fluctuations, due to changes in the general level of U.S. interest rates, and foreign currency exchange rates.
Interest Rate Risk
We do not use derivative financial instruments as a hedge against interest rate fluctuations, and, as a result, we are subject to interest rate risk on our Term Loan and Revolving Loan with variable interest rates based on LIBOR plus a margin as defined in the credit agreement governing the Term Loan and Revolving Loan. As of December 31, 2020, we had outstanding borrowings under our Term Loan and Revolving Loan of $12.5 million and $7.6 million, respectively, at the weighted-average variable interest rates of 2.5% and 2.4%, respectively. At this borrowing level, a 0.25% increase in interest rates would have had an unfavorable annual impact on our pre-tax earnings and cash flows in the amount of $0.05 million.
Foreign Currency Exchange Rate Risk
Following our acquisition of OptaSense on December 3, 2020, we are exposed to risks from foreign currency exchange rate fluctuations on the translation of our foreign operations into U.S. dollars and on the purchase of goods by these foreign operations that are not denominated in their functional currencies. As of December 31, 2020, our exposure to foreign currency rate fluctuations is not material to our financial condition or results of operations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Board of Directors and Stockholders
Luna Innovations Incorporated
Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Luna Innovations Incorporated (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income, changes in stockholders’ equity, and cash flows for the years then ended, and the related notes and financial statement schedule included under Item 15(a) (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, 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.
Basis for opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s 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 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 financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical audit matters
The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which it they relate.
Revenue recognition on the Company’s fixed price contract revenue
As described further in Note 1 to the consolidated financial statements, the Company performs technology research under fixed price contracts with the associated revenue recognized over time. For fixed price revenue contracts recognized over time, management utilizes the input method to measure progress toward the complete satisfaction of the performance obligations based upon the cost incurred to date as a percentage of the total estimated cost. We identified revenue recognition for fixed price contracts as a critical audit matter.
The principal consideration for our determination that revenue recognition for fixed price contracts was a critical audit matter is that the measure of progress towards completion utilizes assumptions for future costs to complete the performance obligations, and those assumptions have significant estimation uncertainty. A significant change in the assumptions could affect the profitability of the contract. Auditing such assumptions required extensive audit effort due to the volume and complexity of these contracts and a high degree of auditor judgment when performing audit procedures and evaluating the results of those procedures.
Our audit procedures related to testing revenue recognition of fixed-price contracts included the following, among others.
•We evaluated the design effectiveness of controls over the Company’s process for recognizing revenue over time. This included the design of controls over the initial budgeting process and proportional performance determination.
•For a sample of contracts, we inquired regarding the status of the project and obtained an understanding for significant changes in budgeted to actual costs.
•For a sample of contracts, we tested the completeness and accuracy of costs incurred to date.
•We inspected a sample of contracts to evaluate the existence of an enforceable right to payment for performance completed to date, while evaluating the progress towards completion of contracts based on costs incurred, evaluating the reasonableness of management’s estimate of profit margins by comparing contract to date profit margins to year to date profit margins and tested the appropriateness of timing and amount of revenue recognized.
•To evaluate management’s ability to estimate progress towards completion, we selected a sample of firm fixed price contracts completed during the year, and obtained the internal budget at inception and compared the budgeted margin to the margin upon completion. We also selected an additional sample of fixed price contracts completed during the year and compared the costs incurred during the current year to the costs that were estimated to be incurred at completion as of the prior year end.
Business Combination - OptaSense Holdings Limited
As described in Note 1 to the consolidated financial statements, the Company acquired OptaSense Holdings Limited in December 2020. This acquisition was accounted for as a business combination. We identified the evaluation of the acquisition date fair value of the intangible assets acquired as a critical audit matter.
The principal consideration for our determination that the evaluation of the acquisition date fair values of the intangible assets acquired was a critical audit matter is the high degree of subjective auditor judgment associated with evaluating management’s determination of the fair values of the acquired intangible assets, which is primarily due to the complexity of the valuation models used and the sensitivity of the underlying significant assumptions. The key assumptions used within the valuation models included prospective financial information, including future revenue growth and an applied discount rate. The calculated fair values are sensitive to changes in these key assumptions.
Our audit procedures related to the evaluation of acquisition date fair values of intangible assets acquired included the following, among others.
•We evaluated the design effectiveness of certain controls over the acquisition-date valuation process, including controls over the development of the key assumptions such as the revenue growth and the applied discount rate.
•We obtained the purchase price allocation analyses from management and the third-party specialist engaged by management. We assessed the qualifications and competence of management and the third-party specialist and evaluated the methodologies used to determine the fair values of the intangible assets.
•We tested the assumptions used within the discounted cash flow models to estimate the fair values of the intangible assets, which included key assumptions such as the future revenue growth and the applied discount rate.
•We assessed the reasonableness of management’s forecast by inquiring with management to understand how the forecast was developed and comparing the projections to historical results and external sources including industry trends and peer companies’ historical data;
•We also involved a valuation specialist who assisted in the evaluation and testing performed of the reasonableness of significant assumptions to the models, including the applied discount rate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Organization and Summary of Significant Accounting Policies
Luna Innovations Incorporated (“we” or the "Company”), headquartered in Roanoke, Virginia, was incorporated in the Commonwealth of Virginia in 1990 and reincorporated in the State of Delaware in April 2003. We are a leader in advanced optical technology, providing high performance fiber optic test, measurement and control products for the telecommunications and photonics industries; and distributed fiber optic sensing solutions that measure, or “sense,” the structures for industries ranging from aerospace, automotive, energy, oil and gas, security and infrastructure.
Consolidation Policy
Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and include our accounts and the accounts of our wholly owned subsidiaries. We eliminate from our financial results all intercompany transactions.
Use of Estimates
The preparation of our consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements and accompanying notes.
Although these estimates are based on our knowledge of current events and actions we may undertake in the future, actual results may differ from such estimates and assumptions.
Revenue Recognition
Lightwave Revenues
Revenues from product sales are generated by the sale of commercial products and services under various sales programs to the end user and through distribution channels. We sell fiber optic test and sensing systems to end users for use in numerous fiber optic-based measurement applications. Revenues are recorded net of applicable sales taxes collected from customers and payable to state or local governmental entities.
For Lightwave contracts, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. We recognize revenue when the performance obligation has been satisfied by transferring the control of the product or service to the customer. For tangible products that contain software that is essential to the tangible product’s functionality, we consider the product and software to be a single performance obligation. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation based on their relative stand-alone selling prices. In such circumstances, we use the observable price of goods or services which are sold separately in similar circumstances to similar customers. If these prices are not observable, then we will estimate the stand-alone selling price using information that is reasonably available. For the majority of our standard products and services, price list and discount structures related to customer type are available. For products and services that do not have price list and discount structures, we may use one or more of the following: (i) adjusted market assessment approach, (ii) expected cost-plus a margin approach, and (iii) residual approach. The adjusted market approach requires us to evaluate the market in which we sell goods or services and estimate the price that a customer in that market would be willing to pay for those goods or services. The expected cost plus margin approach requires us to forecast our expected costs of satisfying the performance obligation and then add a reasonable margin for that good or service. The residual approach decreases the total transaction price by the sum of the observable standalone selling prices if either the company sells the same good or services to different customers for a broad range of amounts or the company has not established a price for the good or service and that good or service has not been sold on a standalone basis. Shipping and handling activities primarily occur after a customer obtains control and are considered fulfillment cost rather than separate performance obligations. Similarly, sales and similar taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer are excluded from the measurement of the transaction price.
For standard products, we recognize revenue at a point in time when control passes to the customer. Absent substantial product acceptance clauses, this is based on the shipping terms. For custom products that require engineering and development based on customer requirements, we will recognize revenue over time using the output method for any items shipped and any finished goods or work in process that is produced for balances of open sales orders. For any finished goods or work in process
that has been produced for the balance of open sales orders we recognize revenue by applying the average selling price for such open order to the lesser of the on-hand balance in finished goods or open sales order quantity which we present as a contract asset on the balance sheet. Cost of sales is recognized based on the standard cost of the finished goods and work in process associated with this revenue and inventory balances are reduced accordingly. For extended warranties and product rentals, revenue is recognized over time using the output method based on the time elapsed for the warranty or service period. In the case of warranties, we record a contract liability for amounts billed but that are not recognized until subsequent periods. A separate contract liability is recorded for the cost associated with warranty repairs based on our estimate of future expense. For testing services where we are performing testing on an asset the customer controls, revenue is recognized over time by the output method using the performance to date. For training where the customer is receiving the benefit of training as it is occurring and for repairs to a customer-controlled asset, revenue is recognized over time by the output method using the performance to date. For royalty revenue, we apply the practical expedient “royalty exception” recognizing revenue based on the royalty agreement which specifies an amount based on sales or minimum amount, whichever is greater.
In some product rental contracts, a customer may be offered a discount on the purchase of an item that would provide for a material right. When a material right has been provided to a customer, a separate performance obligation is established, and a portion of the rental revenue will be deferred until the future product is purchased or the option expires. This deferred revenue is recognized as a contract liability on the balance sheet.
Luna Labs Revenues
We perform research and development for U.S. Federal government agencies, educational institutions and commercial organizations. We account for a research contract when a contract has been executed, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of the contract price is considered probable. Revenue is earned under cost reimbursable, time and materials and fixed price contracts. Direct contract costs are expensed as incurred.
Our contracts with agencies of the U.S. government are subject to periodic funding by the respective contracting agency. Funding for a contract may be provided in full at inception of the contract or ratably throughout the contract as the services are provided. In evaluating the probability of funding for purposes of assessing collectability of the contract price, we consider our previous experience with our customers, communication with our customers regarding funding status and our knowledge of available funding for the contract or program. If funding is not assessed as probable, revenue recognition is deferred until realization is reasonably assured.
Under the typical payment terms of our U.S. government contracts, the customer pays us either performance-based payments ("PBPs") or progress payments. PBPs, which are typically used in the firm fixed price contracts, are interim payments based on quantifiable measures of performance or on the achievement of specified events or milestones. Progress payments, which are typically used in our cost type contracts, are interim payments based on costs incurred as the work progresses. For our U.S. government cost-type contracts, the customer generally pays us during the performance period for 80% to 90% of our actual costs incurred. Because the customer retains a small portion of the contract price until completion of the contract and audit of allowable costs, cost type contracts generally result in revenue recognized in excess of billings which we present as contract assets on the balance sheet. Amounts billed and due from our customers are classified as receivables on the balance sheet. For non-U.S. government contracts, we typically receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. We recognize a liability for these advance payments and PBPs paid in advance which are in excess of the revenue recognized and present these amounts as contract liabilities on the balance sheet.
To determine the proper revenue recognition method for research and development contracts, we evaluate whether two or more contracts should be combined and accounted for as one single modified contract and whether the combined or single contract should be accounted for as more than one performance obligation. For instances where a contract has options that were bid with the initial contract and awarded at a later date, we combine the options with the original contract when options are awarded. For most of our contracts, the customer contracts for research with multiple milestones that are interdependent. Consequently, the entire contract is accounted for as one performance obligation. The effect of the combined or modified contract on the transaction price and measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.
Contract revenue recognition is measured over time as we perform because of continuous transfer of control to the customer. For U.S. government contracts which are typically subject to the Federal Acquisition Regulation, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the
contract for convenience, pay us for cost incurred plus a reasonable profit and take control of any work in process. From time to time, as part of normal management processes, facts may change, causing revisions to estimated total costs or revenues expected. The cumulative impact of any revisions to estimates and the full impact of anticipated losses on any type of contract are recognized in the period in which they become known.
Because of control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the services to be provided. We generally use the input method, more specifically the cost-to-cost measure of progress for our contracts because it best depicts the transfer of control to the customer, which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The underlying bases for estimating our contract research revenues are measurable expenses, such as labor, subcontractor costs and materials, and data that are updated on a regular basis for purposes of preparing our cost estimates. Our research contracts generally have a period of performance of six months to three years, and our estimates of contract costs have historically been consistent with actual results. Revisions in these estimates between accounting periods to reflect changing facts and circumstances have not had a material impact on our operating results, and we do not expect future changes in these estimates to be material. The cumulative impact of any revisions to estimates and the full impact of anticipated losses on any type of contract are recognized in the period in which they become known.
Under cost reimbursable contracts, we are reimbursed for costs that are determined to be reasonable, allowable and allocable to the contract and paid a fixed fee representing the profit negotiated between us and the contracting agency. Revenue from cost reimbursable contracts is recognized as costs are incurred plus an estimate of applicable fees earned. We consider fixed fees under cost reimbursable contracts to be earned in proportion to the allowable costs incurred in performance of the contract.
Revenue from time and materials contracts is recognized based on direct labor hours expended at contract billing rates plus other billable direct costs.
Fixed price contracts may include either a product delivery or specific service performance throughout a period. For fixed price contracts that are based on the proportional performance method and involve a specified number of deliverables, we recognize revenue based on the proportion of the cost of the deliverables compared to the cost of all deliverables included in the contract as this method more accurately measures performance under these arrangements. For fixed price contracts that provide for the development and delivery of a specific prototype or product, revenue is recognized based upon the percentage of completion method.
Whether certain costs under government contracts are allowable is subject to audit by the government. Certain indirect costs are charged to contracts using provisional or estimated indirect rates, which are subject to later revision based on government audits of those costs. Management is of the opinion that costs subsequently disallowed, if any, would not likely have a significant impact on revenues recognized for those contracts.
Allowance for Uncollectible Receivables
Accounts receivable are recorded at their face amount, less an allowance for doubtful accounts. We review the status of our uncollected receivables on a regular basis. In determining the need for an allowance for uncollectible receivables, we consider our customers’ financial stability, past payment history and other factors that bare on the ultimate collection of such amounts. The allowance was $0.9 million at each of December 31, 2020 and 2019.
Cash Equivalents
We consider all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. To date, we have not incurred losses related to cash and cash equivalents. Our foreign currency risk on cash and cash equivalents held outside of the US is not material. Cash equivalents at December 31, 2020 and 2019 included $3.1 million and $19.8 million, respectively, invested in U.S. Treasury obligations through a sweep account with our bank. The full value of amounts invested through the sweep account are convertible to cash on a daily basis. Our cash transactions are processed through reputable commercial banks. We regularly maintain cash balances with financial institutions which exceed Federal Deposit Insurance Corporation (“FDIC”) insurance limits. At December 31, 2020 and 2019, we had approximately $7.5 million and $5.0 million, respectively, in excess of FDIC insured limits.
Fair Value Measurements
Our financial assets and liabilities are measured at fair value, which is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. Valuation techniques are based on observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs have created the following fair value hierarchy:
•Level 1-Quoted prices for identical instruments in active markets.
•Level 2-Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant value drivers are observable.
•Level 3-Valuations derived from valuation techniques in which significant value drivers are unobservable.
The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of the short-term nature of these instruments. The carrying amount of lease liabilities approximate fair value because these financial instruments bear interest at rates that approximate current market rates for similar agreements with similar maturities and credit. We consider the terms of the PNC Bank, National Association debt facility, including its interest rate of LIBOR plus a margin ranging from 1.75% to 2.25%, to be at market based upon similar instruments that would be available to us.
Property and Equipment, net
Property and equipment, net, are stated at cost less accumulated depreciation. We record depreciation using the straight-line method over the following estimated useful lives:
Equipment 3 - 7 years
Furniture and fixtures 7 years
Software 3 years
Leasehold improvements Lesser of lease term or life of improvements
Intangible Assets
Intangible assets consist of patents related to certain intellectual property that we have developed or acquired, and identifiable intangible assets recognized in connection with our acquisition of OptaSense Holdings Ltd. ("OptaSense") and General Photonics, Inc. ("GP"). We amortize our identified intangible assets over their estimated useful lives ranging between one and fifteen years and analyze the reasonableness of the remaining useful life whenever events or circumstances indicate that the carrying amount may not be recoverable to determine whether their carrying value has been impaired.
Goodwill
Goodwill is tested annually for impairment in the fourth quarter (October 1st) and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Goodwill is tested for impairment at the reporting unit level. A qualitative assessment can be performed to determine whether it is more likely than not the fair value of the reporting unit is less than its carrying value. If the reporting unit does not pass the qualitative assessment, we compare the fair value of each reporting unit to its carrying value using a quantitative assessment. If the fair value of the reporting unit exceeds its carrying value, goodwill is considered not impaired. If the fair value of the reporting unit is less than the carrying value, the difference is recorded as an impairment loss.
For the quantitative assessment, we estimate the fair value of each reporting unit using a combination of an income approach using a discounted cash flow ("DCF") analysis and a market-based valuation approach based on comparable public company trading values. Determining the fair value of a reporting unit requires the exercise of significant management judgments, including the amount and timing of projected future revenues, earnings and cash flows after considering factors such as recent operating performance, general market and industry conditions, existing and expected future contracts, changes in working capital and long-term business plans and growth initiatives. The carrying value of each reporting unit includes the assets and liabilities employed in its operations and goodwill. There are no significant allocations of amounts held at the corporate level to the reporting units.
Research, Development and Engineering
Research, development and engineering expense not related to contract performance are expensed as incurred. We expensed $6.7 million and $7.5 million of non-contract related research, development and engineering expense for the year ended December 31, 2020 and 2019, respectively.
Impairment of Long-Lived Assets
We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets is measured by comparing the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Assets to be disposed of by sale are reflected at the lower of their carrying amount or fair value less cost to sell.
Inventory
Inventory consists of finished goods, work in process and raw materials valued at the lower of cost (determined on the first-in, first-out basis) or net realizable value.
Net Income per Share
Basic per share data is computed by dividing net income attributable to common stockholders by the weighted average number of shares outstanding during the period. Diluted per share data is computed by dividing net income attributable to common stockholders by the weighted average shares outstanding during the period increased to include, if dilutive, the number of additional common share equivalents that would have been outstanding if potential common shares had been issued using the treasury stock method. Diluted per share data would also include the potential common share equivalents relating to convertible securities by application of the if-converted method.
The effect of 1.9 million and 3.2 million common stock equivalents are included for the diluted per share data for the years ended December 31, 2020 and 2019, respectively. Accrued stock dividends and stock options are included in our common stock equivalents for the year ended December 31, 2020, while preferred stock is also included for the year ended December 31, 2019.
Stock-Based Compensation
We have two stock-based compensation plans, which are described further in Note 11. We recognize compensation expense based upon the fair value of the underlying equity award as of the date of grant. We have elected to use the Black-Scholes option pricing model to value any stock options granted. Restricted stock and restricted stock units awarded are valued at the closing price of our common stock on the date of the award. We recognize stock-based compensation for such awards on a straight-line method over the requisite service period of the awards taking into account the effects of the expected exercise. We reduce stock-based compensation expense for the value of any forfeitures of unvested awards as such forfeitures occur.
Income Taxes
We account for income taxes using the liability method. Deferred tax assets or liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates, which will be in effect when the differences reverse. A valuation allowance against net deferred tax assets is provided unless we conclude it is more likely than not that the deferred tax assets will be realized.
We recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. We evaluate our ability to benefit from all deferred tax assets and establish valuation allowances for amounts we believe are not more-likely-than-not to be realizable. For uncertain tax positions, we use a more-likely-than-not threshold, greater than 50%, based on the technical merits of the income tax position taken. Income tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit recognized in the financial statements. Penalties, if probable and reasonably estimable, and interest expense related to uncertain tax positions are recognized as a component of the tax provision.
Foreign Currency
For our non-U.S. dollar functional currency subsidiaries, assets and liabilities are translated into U.S. dollars using fiscal year end exchange rates. Sales and expenses are translated at average monthly exchange rates. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive loss within equity. Gains and losses resulting from foreign currency transactions are included in earnings.
Recently Adopted Accounting Pronouncements
In January 2017, the FASB issued ASU 2017-04 Simplifying the Test for Goodwill Impairment, which simplifies the test for goodwill impairment by eliminating Step 2 from the goodwill impairment test which previously measured a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount. We adopted ASU 2017-04, effective January 1, 2020. As a result of adopting the new rules, we compare the estimated fair value of our reporting units to their respective carrying values when evaluating the recoverability of goodwill. If the carrying value of a reporting unit exceeds its fair value, an impairment charge will be recognized for the amount by which its carrying value exceeds the reporting unit's fair value; however, the loss recognized will not exceed the goodwill allocated to the reporting unit. The adoption of ASU 2017-04 did not have a significant impact on our consolidated financial statements.
In August 2018, the FASB issued ASU No. 2018-13 Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement, which amends the disclosure requirements in ASC 820 by adding, changing, or removing certain disclosures. The ASU applies to all entities that are required under this guidance to provide disclosures about recurring or nonrecurring fair value measurements. We adopted these amendments, effective January 1, 2020. The adoption of ASU 2018-13 did not have a significant impact on our consolidated financial statements.
In August 2018, the FASB issued ASU 2018-15 Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted ASU 2018-15, effective January 1, 2020. The adoption of ASU 2018-15 did not have a significant impact on our consolidated financial statements.
Recently Issued Pronouncements not yet adopted
In June 2016, the FASB issued ASU 2016-13 Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments, which requires companies to measure financial assets at an amortized cost basis to be presented at the net amount expected to be collected. The new accounting rules eliminate the probable initial recognition threshold and, instead, reflect an entity's current estimate of all expected credit losses. ASU 2016-13 is applicable to our trade receivables. This pronouncement was amended under ASU 2019-10 to allow an extension on the adoption date for entities that qualify as a small reporting company. We have elected this extension and the effective date for us to adopt this standard will be for fiscal years beginning after December 15, 2022. We are currently in the process of evaluating the impact of ASU 2016-13, but we do not expect the adoption of these new accounting rules to have a significant impact on our consolidated financial statements.
In December 2019, the FASB issued ASU 2019-12 Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles of the accounting for income taxes and also improves consistent application of and simplification of other areas when accounting for income taxes. The guidance is effective for us beginning in the first quarter of fiscal year 2021, while early adoption is permitted. We do not expect the adoption of these new accounting rules to have a significant impact on our consolidated financial statements.
2. Business Acquisitions
OptaSense Holdings Limited
On December 3, 2020, we entered into and closed a Share Purchase Agreement (the “Share Purchase Agreement”) with QinetiQ Holdings Limited (“QinetiQ”) for the purchase of all of the shares of OptaSense, a recognized market leader in fiber optic distributed monitoring solutions for pipelines, oilfield services, security, highways and railways, as well as power and utilities monitoring systems. Pursuant to the Share Purchase Agreement, we acquired all outstanding shares of OptaSense for aggregate consideration of $38.9 million (£29.0 million) subject to adjustment as described in the Share Purchase Agreement (the “Transaction”). The acquisition of OptaSense provides us with important distributed acoustic sensing ("DAS") intellectual
property and products. OptaSense's technology and products and geographic footprint are highly complementary to Luna, which we believe will accelerate our technology and overall growth roadmap.
The Share Purchase Agreement and a Tax Deed entered into between QinetiQ and us (the “Tax Deed”) in connection with the Share Purchase Agreement contain customary representations and warranties and indemnities. In addition, at closing of the acquisition, we obtained a warranty and indemnity insurance policy from Liberty Mutual Insurance Europe SE (LMIE) in connection with the Share Purchase Agreement and the Tax Deed.
In addition, for a period of two years after closing, QinetiQ has agreed not, directly or indirectly, alone or jointly with any other person, to compete or engage in any competing business with us in countries in which OptaSense operates and not to solicit our customers, employees or suppliers, subject to specified exceptions. QinetiQ has also agreed to provide specified transitional services for a period of six months after closing.
For the period from the closing of the OptaSense acquisition through December 31, 2020, we recognized revenue of $1.5 million and an operating loss of $0.9 million. OptaSense's operating loss for the period from the closing of the acquisition through December 31, 2020 included $0.1 million in amortization expense for the acquired intangibles and step-up in value of acquired inventory. The amortization expense for the acquired intangibles as well as the costs associated with the acquisition of GP are included in the cost of goods sold and selling, general and administrative expense in our consolidated statements of operations.
New Ridge Technologies
On October 29, 2020, we acquired New Ridge Technologies, a small company that develops and manufactures fiber optic test and measurement equipment and advanced fiber optic subsystems primarily for telecommunication and radio-over-fiber applications. The company's acquired operations will be integrated into, and reported as a part of, our Lightwave segment. This acquisition supports our growth strategy in the communications test arena. The total consideration was $0.6 million which consisted of $0.4 million paid at closing and $0.2 million of contingent consideration related to an earn-out provision. We recorded $0.02 million of goodwill upon the completion of the purchase consideration allocation. Depending on the achievement of certain metrics during the two years following closing, we may pay the seller up to $0.2 million in contingent consideration related to the earn-out provision.
General Photonics Corporation
On March 1, 2019, we acquired the outstanding stock of GP for cash consideration of $19.0 million. Of the purchase price, $17.1 million was paid at closing and $1.9 million was placed into escrow for possible working capital adjustments to the purchase price and potential satisfaction of certain post-closing indemnification obligations. Additionally, we may become obligated to pay additional cash consideration of up to $1.0 million if certain revenue targets for the GP historical business are met for the twelve-month period following the closing. We estimated the fair value of the contingent obligation to be $1.0 million, which is shown in accrued liabilities on the consolidated balance sheet and was subsequently paid during the year ended December 31, 2020. The fair value of the contingent obligation was determined using the present value of estimated likely future payments.
For the period from the closing of the GP acquisition through December 31, 2019, we recognized revenue of $10.5 million and operating income of $1.4 million. Operating income for the period from the closing of the acquisition through December 31, 2019 included $1.6 million in amortization expense for the acquired intangibles and step-up in value of acquired inventory associated with the acquisition of GP. Operating income for the year ended December 31, 2019 also included $0.9 million of costs associated with the acquisition of GP. The amortization expense for the acquired intangibles as well as the costs associated with the acquisition of GP are included in the cost of goods sold and selling, general and administrative expense in our consolidated statements of operations.
These acquisitions have been accounted for under the acquisition method of accounting in accordance with ASC 805 - Business Combinations. Under ASC 805, the total estimated purchase consideration is allocated to the acquired tangible and intangible assets and assumed liabilities based on their estimated fair values as of the acquisition date. Any excess of the fair value of the acquisition consideration over the identifiable assets acquired and liabilities assumed is recognized as goodwill. The allocation of the purchase consideration for the OptaSense acquisition is preliminary.
The following table summarizes the allocation of the purchase consideration of each acquisition (excluding cash of $5.2 million and $3.8 million, respectively):
(in thousands) OptaSense (2020) GP (2019)

OptaSense's developed technology primarily consists of its DAS product solutions that deliver superior measurements for a wide range of applications from advanced industrial monitoring through high performance geophysical measurements. GP's developed technologies acquired primarily consisted of its technologies relating to the measurement and control of the polarization of light. The developed technologies were valued using the "multi-period excess earnings" method, under the income approach. The multi-period excess earnings method reflects the present value of the projected cash flows that are expected by the developed technologies less charges representing the contribution of other assets to those cash flows. Discount rates of 17.5% and 17% were used to discount these cash flows of OptaSense and GP, respectively, to the present value.
Trade names and trademarks are considered a type of guarantee of a certain level of recognizability, quality or performance represented by the OptaSense and GP brands. Trade names and trademarks were valued using the "relief from royalty" method under the income approach. This method is based on the assumption that in lieu of ownership, a market participant would be willing to pay a royalty in order to exploit the related benefits of these assets. Discount rates of 17.5% and 16% were used to discount these cash flows of OptaSense and GP, respectively, to the present value.
Backlog arises from unfulfilled purchase or sales order contracts. The value of OptaSense's backlog as of the acquisition date was calculated using the income approach. A discount rate of 16.5% was used to discount the cash flows attributable solely to the backlog to the present value.
Customer relationships represent the fair value of either (i) the avoidance of cost associated with the creation of a new customer relationship or (ii) the projected cash flows that will be derived from the sale of products to existing customers as of the acquisition date. OptaSense's customer relationships were valued using the cost approach based on the expected time to re-build the customer base. GP's customer relationships were valued using the "distributor" method, under the income approach.
Under this premise, the margin of a distributor within the industry is deemed to be the margin attributable to customer relationships. This isolates the cash flows attributable to the customer relationships for which a market participant would be willing to pay. Discount rates of 17.5% and 16% were used to discount these cash flows for OptaSense and GP, respectively, to the present value.
Goodwill represents the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed in connection with the acquisition. Goodwill generated from our business acquisitions was primarily attributable to expected synergies from future customer and sales growth.
Pro forma consolidated results of operations
The following unaudited pro forma financial information presents combined results of operations for each of the periods presented as if the acquisitions of OptaSense and GP had been completed on January 1, 2019. The pro forma information includes adjustments to depreciation expense for property and equipment acquired and amortization expense for the intangible assets acquired and the elimination of transaction expenses recognized in each period. Transaction-related expenses associated with the acquisition of OptaSense and excluded from pro forma income from continuing operations were $2.2 million for the year ended December 31, 2020. Transaction-related expenses associated with the acquisition of GP and excluded from pro forma income from continuing operations were $1.0 million for the year ended December 31, 2019.
The pro forma data are for informational purposes only and are not necessarily indicative of the consolidated results of operations or the combined business had the acquisitions of OptaSense and GP occurred on January 1, 2019, or the results of future operations of the combined business. For instance, planned or expected operational synergies following the acquisition are not reflected in the pro forma information.

PNC Bank Facility
On December 1, 2020 (the “Effective Date”), we entered into a Loan Agreement (the “Loan Agreement”) with PNC Bank, National Association, as lender (the “Lender”) and our domestic subsidiaries as guarantors. The Loan Agreement provides a $12.5 million term loan facility (the “Term Loan”) and a $15.0 million revolving credit facility (the “Revolving Line”), which includes a $3.0 million letter of credit sublimit. On the Effective Date, we borrowed the full amount of the Term Loan from the Lender pursuant to a term note (the “Term Note”) and a $7.6 million revolving loan (the “Revolving Loan”) pursuant to a revolving line of credit note (the “Revolving Line of Credit Note”). We may repay and reborrow advances under the Revolving Line from time to time pursuant to the Revolving Line of Credit Note.
The Term Loan matures on December 1, 2023. The Term Loan is due and payable in 12 equal quarterly payments of principal and interest. The Term Loan bears interest at a floating per annum rate equal to the sum of (a) LIBOR plus (b) a margin ranging from 1.75% to 2.25% depending on the Net Leverage Ratio (as defined in the Loan Agreement). We may prepay the Term Loan without penalty or premium.
The Revolving Line expires on December 1, 2023. Borrowings under the Revolving Line will bear interest at a floating per annum rate equal to the sum of (a) LIBOR plus (b) a margin ranging from 1.75% to 2.25% depending on the Net Leverage Ratio. Accrued interest will be due and payable on the first day of each month and the outstanding principal balance and any accrued but unpaid interest will be due and payable on December 1, 2023. The unused portion of the Revolving Line will accrue a fee equal to 0.20% per annum multiplied by the quarterly average unused amount.
Provided our obligations under the Loan Agreement have been satisfied, we may terminate the Loan Agreement at any time upon three business days’ advance written notice to the Lender.
The Loan Agreement includes a number of affirmative and restrictive covenants applicable to us and our subsidiaries, including, among others, financial covenants regarding minimum net leverage and fixed charge coverage, affirmative covenants regarding delivery of financial statements, payment of taxes, and maintenance of government compliance, and restrictive covenants regarding dispositions of property, acquisitions, incurrence of additional indebtedness or liens, investments and transactions with affiliates. We are also restricted from paying dividends or making other distributions or payments on our capital stock, subject to limited exceptions. We were in compliance with these covenants as of December 31, 2020.
Upon the occurrence of certain events, including failure to satisfy our payment obligations under the Loan Agreement, failure to adhere to the financial covenants, the breach of certain of our other covenants under the Loan Agreement, cross defaults to other indebtedness or material agreements, judgment defaults and defaults related to failure to maintain governmental approvals, the Lender will have the right, among other remedies, to declare all principal and interest immediately due and payable, and to exercise secured party remedies.
Silicon Valley Bank Facility
We maintained a Loan and Security Agreement (the "Credit Facility") with Silicon Valley Bank ("SVB") under which we had a term loan with an original borrowing amount of $6.0 million (the “Original Term Loan”). The Original Term Loan carried a floating annual interest rate equal to SVB’s prime rate then in effect plus 2%. The Original Term Loan matured and was repaid in May 2019.
On October 8, 2020, we entered into an Amended and Restated Loan and Security Agreement (the “A&R Loan Agreement”) with SVB, which amended and restated in its entirety our previous Loan and Security Agreement dated as of October 10, 2019, as amended. Under the A&R Loan Agreement, SVB agreed to make advances available up to $10.0 million
(the “A&R Revolving Line”). If we borrow from the A&R Revolving Line, such borrowing would carry a floating annual interest rate equal to the greater of (i) the Prime Rate (as defined in the Loan Agreement) then in effect plus .50% or (ii) 4.75%. Amounts borrowed under the A&R Revolving Line may be repaid and, prior to the A&R Revolving Line Maturity Date (defined below), reborrowed. The Revolving Line terminates on October 10, 2021 (the “A&R Revolving Line Maturity Date”), unless earlier terminated by us.
Amounts due under the A&R Loan Agreement are secured by our assets, including all personal property and bank accounts; however, intellectual property is not secured under the Loan Agreement. The Loan Agreement requires us to observe a number of financial and operational covenants, including maintenance of a specified Liquidity Coverage Ratio (as defined in the A&R Loan Agreement), protection and registration of intellectual property rights and customary negative covenants. As of December 31, 2020, there were no events of default on the Credit Facility.
On December 1, 2020, we terminated the A&R Loan Agreement, dated October 8, 2020. As of the time of termination, there were no amounts outstanding under the A&R Loan Agreement.
On April 28, 2020, we were granted a loan (the "Loan") from SVB in the aggregate amount of $4.5 million, pursuant to the Paycheck Protection Program under Division A, Title I of the CARES Act, which was enacted March 27, 2020.
On May 4, 2020, we returned the full amount of the proceeds of the Loan to SVB. The decision to return the proceeds was based on the revised guidance issued by the U.S. Department of Treasury and the Small Business Administration subsequent to our application for the Loan.
Maturities on debt are as follows (in thousands):

10. Leases
We have operating leases for our facilities, which have remaining terms ranging from 1 to 5 years. Our leases do not have an option to extend the lease period beyond the stated term unless the new term is agreed by both parties. They also do not have an early termination clause included. Our operating lease agreements do not contain any material restrictive covenants. Some of our operating lease agreements contain variable payment provisions that provide for rental increases based on consumer price indices. The change in rent expense resulting from changes in these indices are included within variable rent.
We also have finance leases for equipment which have remaining terms ranging from 1 to 4 years. These lease agreements are for general office equipment with a 5-year useful life. These lease agreements do not have an option to extend the lease beyond the stated terms nor do they have an early termination clause. These lease agreements do not have any variable payment provisions included. The finance lease costs consist of interest expense and amortization, and are included primarily in selling, general and administrative expense in our consolidated statement of operations.
The discount rate for both our operating and finance leases was not readily determinable in the specific lease agreements. As a result, our incremental borrowing rate was used as the discount rate when establishing the ROU assets and corresponding lease liabilities. As of December 31, 2020, we had no operating or finance leases that have not yet commenced.
Rent expense is recognized on a straight-line basis over the life of the lease. Rent expense consists of the following:

11. Stockholders’ Equity
Series A Convertible Preferred Stock
In January 2010, we entered into a transaction with Carilion, in which Carilion agreed to exchange all of its Senior Convertible Promissory Notes with an original principal amount of $5.0 million plus all accrued but unpaid interest, totaling $1.2 million, for 1,321,514 shares of our newly designated Series A Convertible Preferred Stock. The Series A Convertible Preferred Stock is non-voting, carries a dividend of 6% payable in shares of common stock and maintains a liquidation preference up to $6.2 million. In September 2019, Carilion elected to convert the 1,321,514 shares of preferred stock into an equal number of shares of our common stock. In addition, we issued 770,454 shares of our common stock in satisfaction of the accrued dividends earned on the preferred stock prior to its conversion.
Equity Incentive Plans
In April 2016, we adopted our 2016 Equity Incentive Plan (the "2016 Plan") as a successor to the 2006 Plan. Under the 2016 Plan, our Board of Directors is authorized to grant both incentive and non-statutory stock options to purchase common stock and restricted stock awards to our employees, directors, and consultants. The 2016 Plan provides for the issuance of 3,500,000 shares plus any amounts forfeited from grants under the 2006 Plan after the expiration date of the 2006 Plan. Options generally have a life of 10 years and exercise price equal to or greater than the fair market value of the Common Stock as determined by the Board of Directors. Vesting typically occurs over a four-year period.
The following table sets forth the activity of the options to purchase common stock under the 2006 Plan and the 2016 Plan. The prices represent the closing price of our Common Stock on the Nasdaq Capital Market on the respective dates.

(1)The intrinsic value of an option represents the amount by which the market value of the stock exceeds the exercise price of the option of in-the-money options only.
The fair value of each option granted is estimated as of the grant date using the Black-Scholes option pricing model with the following assumptions:
Years ended December 31,
2020 2019
Risk-free interest rate range 0.7% 2.494%
Expected life of option-years 7 7
Expected stock price volatility 63% 67%
Expected dividend yield -% -%
The risk-free interest rate is based on U.S. Treasury interest rates, the terms of which are consistent with the expected life of the stock options. Expected volatility is based upon the average historical volatility of our common stock over the period commensurate with the expected term of the related instrument. The expected life and estimated post-employment termination behavior is based upon historical experience of homogeneous groups, executives and non-executes, within our company. We do not currently pay dividends on our common stock nor do we expect to in the foreseeable future.

For the years ended December 31, 2020 and 2019, the weighted average grant date fair value of options granted was $6.65 and $3.63 per share, respectively. We estimate the fair value of options at the grant date using the Black-Scholes model. For all stock options granted through December 31, 2020, the weighted average remaining service period is 6.0 years.
Unamortized stock option expense at December 31, 2020 that will be amortized over the weighted-average remaining service period of 2.0 years totaled $2.1 million.
Restricted Stock and Restricted Stock Units
Historically, we have granted shares of restricted stock to certain employees that have vested in three equal annual installments on the anniversary dates of their grant. However, beginning in 2019, we altered our approach for these grants to replace the grant of restricted stock subject to time-based vesting with the grant of a combination of restricted stock units ("RSUs") subject to time-based vesting and performance-based vesting. Each RSU represents the contingent right to receive a single share of our common stock upon the vesting of the award. For the year ended December 31, 2020, we granted an aggregate of 138,650 RSUs to certain employees. Of the RSUs granted during 2020, 76,700 of such RSUs are subject to time-based vesting and are scheduled to vest in three equal annual installments on the anniversary dates of the grant. The remaining 61,950 RSUs are performance-based awards that will vest based on our achievement of long-term performance goals, in particular, based on our levels of 2022 revenue and operating income. The 61,950 shares issuable upon vesting of the performance-based RSUs represent the maximum payout under our performance-based awards, based upon 150% of our target performance for 2022 revenue and operating income (the payout of such awards based on target performance for 2022 revenue and operating income would be 41,300 shares). In the case of the time-based and performance-based RSUs, vesting is also subject to the employee's continuous service with us through vesting. In 2020, 137,997 shares of restricted stock and 72,335 RSUs granted to employees vested.
In addition, in conjunction with our 2018, 2019 and 2020 Annual Meetings of Stockholders, we granted RSUs to certain members of our Board of Directors in respect of the annual equity compensation under our non-employee director compensation policy (other members of our Board of Directors elected to receive their annual equity compensation for Board service in the form of stock units under our Deferred Compensation Plan as described below). RSUs granted to our non-employee Directors vest at the earlier of the one-year anniversary of their grant or the next annual stockholders' meeting. In 2020 and 2019, we granted 10,652 and 11,600, respectively, RSUs to non-employee members of our Board of Directors in respect of the annual equity compensation under our non-employee director compensation policy. In 2020 and 2019, 11,600 and 16,286 RSUs, respectively, vested.
The following table summarizes the number of unvested shares underlying our restricted stock awards and RSUs and the value of our unvested restricted stock awards and RSUs in 2020 and 2019:

We recognized $2.1 million and $1.5 million in stock-based compensation expense, which is recorded in selling, general and administrative expense on the consolidated statement of operations for the years ended December 31, 2020 and 2019, respectively.
Unamortized restricted stock and RSUs expense at December 31, 2020 that will be amortized over the weighted-average remaining service period of 1.7 years totaled $1.2 million.
Employee Stock Purchase Plan
On April 7, 2020, our board of directors approved, and on May 11, 2020, our stockholders approved, the Luna Innovations Incorporated 2020 Employee Stock Purchase Plan (the "2020 ESPP"). The 2020 ESPP grants our eligible employees a purchase right to purchase up to that number of shares of common stock purchasable either with a percentage or with a maximum dollar amount, as designed by the Board of Directors, during the period that begins on the offering date and ends on the date stated in the offering. The maximum number of shares of common stock that may be issued under the 2020 ESPP is 1,200,000 shares. The 2020 ESPP is considered a compensatory plan and the fair value of the discount and the look-back period will be estimated using the Black-Scholes option pricing model and expense will be recognized over the six-month withholding period prior to the purchase date. For the year ended December 31, 2020, we recognized $0.2 million in share-based compensation expense related to the 2020 ESPP, which is included in our selling, general and administrative expense in the accompanying consolidated statement of operations.
Non-employee Director Deferred Compensation Plan
We maintain a non-employee director deferred compensation plan (the “Deferred Compensation Plan”) that permits our non-employee directors to defer receipt of certain compensation that they receive for serving on our board and board committees. The Deferred Compensation Plan has historically permitted the participants to elect to defer cash fees to which they were entitled for board and committee service. For participating directors, in lieu of payment of cash fees, we credit their accounts under the Deferred Compensation Plan with a number of stock units based on the trading price of our common stock as of the date of the deferral. These stock units vest immediately, although the participating directors do not receive the shares represented by such units until a future qualifying event.
Pursuant to our Deferred Compensation Plan, non-employee directors can also elect to defer the receipt of some or all of the equity compensation that they receive for board and committee service. Stock units representing this equity compensation vest at the earlier of the one-year anniversary of their grant or the next annual stockholders' meeting.
The following is a summary of our stock unit activity under the Deferred Compensation Plan for 2020 and 2019:
(in thousands, except stock units and weighted-average share data) Number of Stock Units Weighted Average Grant Date Fair Value per Share Intrinsic Value Outstanding
Balance, January 1, 2019 507,290 $ 1.40 $ 1,699

Balance, December 31, 2020 635,383 $ 2.41 $ 6,278
As of December 31, 2020, 24,855 outstanding stock units had not yet vested.
Stock Repurchase Program
In August 2019, our board of directors authorized a stock repurchase program which allowed us to repurchase up to $2.0 million of our common stock through August 2020. As of December 31, 2020, we had repurchased a total of 333,953 shares for an aggregate purchase price of $2.0 million under this stock repurchase program, all of which had been repurchased before the program expired in September 2019. We currently maintain all repurchased shares under this stock repurchase program as treasury stock.
12. Revenue Recognition
Disaggregation of Revenue
We disaggregate our revenue from contracts with customers by geographic locations, customer type, contract type, timing of recognition, and major categories for each of our segments, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. We disaggregate revenue on the basis of where the physical goods are shipped. We also classify revenue by the customer type of entity for which it does business, which is an
indicator of the diversity of our client base. We attribute revenues generated from being a subcontractor to a commercial company as government revenue when the ultimate client is a government agency or department. Disaggregation by contract mix provides insight in terms of the degree of performance risk that we have assumed. Fixed-price contracts are considered to provide the highest amount of performance risk as we are required to deliver a scope of work or level of effort for a negotiated fixed price. Cost-based contracts are considered to provide the lowest amount of performance risk since we are generally reimbursed for all contract costs incurred in performance of contract deliverables with only the amount of incentive or award fees (if applicable) dependent on the achievement of negotiated performance requirements. By classifying revenue by major product and service, we attribute revenue from a client to the major product or service that we believe to be the client's primary market.

Contract Balances
Our contract assets consist of unbilled amounts for technology development contracts as well as custom product contracts. Also included in contract assets are royalty revenue and carrying amounts of right of returned inventory. Long-term contract assets include the fee withholding on cost reimbursable contracts that will not be billed within a year. Contract liabilities
include excess billings, subcontractor accruals, warranty expense, extended warranty revenue, right of return refund, and customer deposits. The net contract assets/(liabilities) changed by $1.1 million primarily due to an increased number of government research programs, primarily fixed-price contracts, that have not reached milestones as designated in their respective contracts, but revenue has been recognized based on costs incurred.
The following table shows the components of our contract balances as of December 31, 2020 and 2019:
December 31,
(in thousands) 2020 2019
Contract assets $ 7,517 $ 3,208
Contract liabilities (7,095) (3,888)
Net contract assets/(liabilities) $ 422 $ (680)
Performance Obligations
Unfulfilled performance obligations represent amounts expected to be earned on executed contracts. Indefinite delivery and quantity contracts and unexercised options are not reported in total unfulfilled performance obligations. Unfulfilled performance obligations include funded obligations, which is the amount for which money has been directly authorized by the U.S. government and for which a purchase order has been received by a commercial customer, and unfunded obligations represent firm orders for which funding has not yet been appropriated. The approximate value of our Lightwave segment's unfulfilled performance obligations was $35.9 million at December 31, 2020. We expect to satisfy 77% of the performance obligations in 2021, 15% in 2022 and the remainder by 2025. The approximate value of our Luna Labs segment's unfulfilled performance obligations was $19.0 million at December 31, 2020. We expect to satisfy 70% of the performance obligations in 2021, 27% in 2022 and the remainder by 2023.

The realization of our deferred income tax assets is dependent upon sufficient taxable income in future periods. In assessing whether deferred tax assets may be realized, we consider whether it is more likely than not that some portion, or all, of the deferred tax asset will be realized. We consider scheduled reversals of deferred tax liabilities, projected future taxable income and tax planning strategies that we can implement in making our assessment. We have net operating loss ("NOL") carryforwards of approximately $5.2 million for a previously acquired company expiring at varying dates through 2033. Our NOL carryovers will be subject to a Section 382 limitation based on a 2015 ownership change, and there have been no subsequent ownership changes. We continue to be in a three year cumulative net income position, and based on all available positive and negative evidence, we believe our net deferred tax asset will be fully realizable.
Our OptaSense acquisition included a UK entity and a US entity which have deferred tax assets. Based on all available evidence, including cumulative history of losses, we have realized deferred tax assets only to the extent they are supported by the reversal of existing temporary differences. As a result, we have recorded a valuation allowance of $2.9 million as of December 31, 2020.
The following table summarizes the activity related to our gross unrecognized tax benefits:
Years ended December 31,
(in thousands) 2020 2019
Unrecognized tax benefits, beginning of period $ - $ -
Increases related to current period tax positions 81 -
Increases related to prior period tax positions 130 -
Unrecognized tax benefits, end of period $ 211 $ -
As of December 31, 2020, we had $0.2 million of unrecognized tax benefits. If these amounts are recognized in future periods, it would affect the effective tax rate on income from continuing operations for the years in which they are recognized. Interest and penalties released related to uncertain tax positions were not material for the year ended December 31, 2020. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the overall income tax provision in the period for which the event occurs requiring the adjustment. The amount of accrued interest and penalties as of December 31, 2020 is recorded in other long-term liabilities on the consolidated balance sheets. Our policy is to recognize interest and/or penalties related to income tax matters in income tax expense. We do not believe there are any positions for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within the next 12 months.
We file numerous consolidated and separate income tax returns in the US federal jurisdiction and in many state and foreign jurisdictions. The U.S. federal statute of limitations remains open for the year 2017 and onward. U.S. state jurisdictions have statutes of limitation generally ranging from three to seven years. Our OptaSense companies have open years for audit including UK - 2017 and forward; US - 2017 and forward; and Canada - 2016 and forward. Given that certain subsidiaries have federal or state net operating loss carryforwards, the statute for examination by the taxing authorities will typically remain open for a period following the use of such net operating loss carryforwards, extending the period for examination beyond the years indicated above. We currently have no income tax returns under examination,
On March 27, 2020, the United States enacted the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"). The CARES Act includes significant business tax provisions that, among other things, include the removal of certain limitations on utilization of net operating losses, increase the loss carryback period for certain losses to five years, and increase the ability to deduct interest expense, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act. We do not expect the CARES Act to have a significant impact on our tax obligations. In December 2020, the Consolidated Appropriations Act, 2021 (“CAA”) was signed into law. The CAA included additional funding through tax credits as part of its economic package for 2021. We evaluated these items in its tax computation as of December 31, 2020 and determined that the items do not have a material impact on our financial statements as of December 31, 2020.
14. Commitments and Contingencies
Litigation and other contingencies
From time to time, we may become involved in litigation in relation to claims arising out of our operations in the normal course of business. While management currently believes it is not reasonably possible the amount of ultimate liability, if any, with respect to these actions will have a material adverse effect on our financial position, results of operations or liquidity, the ultimate outcome of any litigation is uncertain.
In December 2018, we received a notice of claim (the "Claim") from Macom Technology Solutions, Inc. ("Macom"), who acquired our HSOR business in August 2017 pursuant to an asset purchase agreement. Under the asset purchase agreement, we agreed to indemnify Macom for certain matters, including, among other things, the collection of accounts receivable from certain major customers, and placed $4.0 million of the purchase price into an escrow account for the potential settlement of any valid indemnity claims. As of December 31, 2019, $1.5 million of the escrow balance had been received with the remaining $2.5 million in the escrow account pending resolution of our dispute of indemnity claims received from Macom. In March 2020, we settled the dispute resulting in us receiving $0.6 million and Macom receiving $1.9 million. For the year ended December 31, 2020, we have recorded a loss from discontinued operations of $1.4 million, net of income tax benefit, to reflect the settlement of the dispute.
On July 31, 2018, we sold the assets associated with our optoelectronic components and sub-assemblies ("Opto") business to an unaffiliated third party. The asset purchase agreement provides for additional consideration of up to $1.0 million
contingent upon the achievement of a specified revenue level by the sold business during the 18 months following the sale. We did not receive any of the additional $1.0 million of consideration because the minimum revenue targets were not achieved.
We have made, and will continue to make, efforts to comply with current and future environmental laws. We anticipate that we could incur additional capital and operating costs in the future to comply with existing environmental laws and new requirements arising from new or amended statutes and regulations. In addition, because the applicable regulatory agencies have not yet promulgated final standards for some existing environmental programs, we cannot at this time reasonably estimate the cost for compliance with these additional requirements. The amount of any such compliance costs could be material. We cannot predict the impact that future regulations will impose upon our business.
Obligation under Operating Leases
See Note 10 - Leases for discussion of our lease obligations.
Purchase Commitment
We executed a non-cancelable purchase order totaling $1.4 million in the third quarter of 2020 and a non-cancelable purchase order totaling $1.6 million in the fourth quarter of 2020 for multiple shipments of tunable lasers to be delivered over an 12-month period. At December 31, 2020, approximately $2.9 million of these commitments remained and is expected to be delivered by October 31, 2021.
Guarantees
As of December 31, 2020, we had a total of $1.2 million in performance bond guarantees outstanding in favor of certain third parties to ensure performance of its obligations under certain customer contracts and lease arrangements. These guarantees expire at various dates through September 2022. To date, we have not incurred any charges associated with non-performance covered by such guarantees and have not accrued any liabilities as of December 31, 2020.
15. Employee Profit Sharing Plan
We maintain a salary reduction/profit-sharing plan under provisions of Section 401(k) of the Internal Revenue Code. The plan is offered to all permanent employees. We contribute 30% of the salary deferral elected by each employee up to a maximum deferral of 10% of annual salary.
We contributed approximately $0.5 million and $0.4 million to the plan for the years ended December 31, 2020 and December 31, 2019, respectively.
16. Relationship with Major Customers
During the years ended December 31, 2020 and 2019, approximately 35% and 40%, respectively, of our consolidated revenues were attributable to contracts with the U.S. government.
At December 31, 2020 and 2019, receivables with respect to contracts with the U.S. government represented 14% and 12% of total trade receivables, respectively.
17. Financial Information About Segments
We have two operating and reportable segments: Lightwave and Luna Labs.
During the year ended December 31, 2020, we changed our reportable segments to Lightwave and Luna Labs to align with how our Chief Operating Decision Maker (CODM) evaluates segment performance and allocates resources to the segments. Prior to the year ended December 31, 2020, we reported under two different reporting segments. We have reflected these new segment measures beginning in the year ended December 31, 2020 and prior periods have been restated for comparability.
The Lightwave segment develops, manufactures and markets distributed fiber optic sensing products and fiber optic communications test and control products. The Luna Labs segment performs applied research principally in the areas of sensing and instrumentation, advanced materials and health sciences.
Through December 31, 2020, our Chief Executive Officer and his direct reports (collectively represented our CODM), evaluated segment performance based primarily on revenues and operating income or loss. The accounting policies of our segments are the same as those described in the summary of significant accounting policies in Note 1, “Organization and Summary of Significant Accounting Policies”.
Information about the results of operations for each segment is set forth in the table below. There were no significant inter-segment sales during the years ended December 31, 2020 and 2019.
During the years ended December 31, 2020 and 2019, 31% and 32%, respectively, of our total sales took place outside the United States. Customers in China represented 11% of total revenues for the year ended December 31, 2019, while no other single country, outside of the United States, represented more than 10% of total revenues for the year ended December 31, 2020.

ITEM 9A. CONTROLS AND PROCEDURES
ITEM 9A. CONTROLS AND PROCEDURES.
Evaluation of Disclosure Controls and Procedures
We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which are controls and other procedures that are designed to provide reasonable assurance that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected.
Under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. As a result of a late Form 8-K/A pertaining to the filing of audited financial statements for a recently acquired company, our President and Chief Executive Officer and our Chief Financial Officer have concluded that, as of December 31, 2020, our disclosure controls and procedures were not effective as of the end of the period covered by this report. The delinquent filing was an isolated incident and the Company has instituted additional procedures designed to ensure timely filings in the future.
Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Securities Exchange Act Rule 13a-15(e) and Rule 15d-15(e) that occurred in the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed, under the supervision of our principal executive and principal financial officers, and effected by our board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Our internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
On December 3, 2020, we completed our acquisition of OptaSense. Management is in the process of evaluating OptaSense’s existing controls and procedures, and integrating OptaSense into our internal control over financial reporting. In accordance with SEC staff guidance permitting a company to exclude an acquired business from management’s assessment of the effectiveness of internal control over financial reporting for the year in which the acquisition is completed, management has excluded OptaSense from its assessment of the effectiveness of internal control over financial reporting as of December 31, 2020. OptaSense represents 36% percent of our total assets as of December 31, 2020 and 2% percent of revenue for the year ended December 31, 2020.
There are inherent limitations in the effectiveness of any internal control over financial reporting, including the possibility of human error and the circumvention or overriding of controls. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation and may not prevent or detect all misstatements. Further, because of changes in conditions, effectiveness of internal control over financial reporting may vary over time. Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.
Under the supervision and with the participation of our management, including our President and Chief Executive Officer, and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2020. This evaluation was based on the criteria established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Based on our evaluation under the framework established in the 2013 Internal Control-Integrated Framework, our President and Chief Executive officer, and our Chief Financial Officer concluded that our internal control over financial reporting was effective as of December 31, 2020 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.
