ITEM 1. BUSINESS
ITEM 1. BUSINESS OVERVIEW
Rubicon Technology, Inc. (“Rubicon” or the “Company”) currently consists of one operating subsidiary, Rubicon Technology Worldwide LLC (“RTW”). In June 2021 the operations of Rubicon DTP LLC (“Direct Dose” or DDRX”) were discontinued.
RTW is an advanced materials provider specializing in monocrystalline sapphire for applications in optical and industrial systems. Sapphire is a desirable material for high-performance applications due to its hardness and strength, transparency in the visible and infrared spectrum, thermal conductivity, thermal shock resistance, abrasion resistance, high melting point and chemical inertness. As a result, it is ideally suited for extreme environments in a range of industries where material durability is just as important as optical clarity. We believe that we continue to have a reputation as one of the highest quality sapphire sources in the market. We provide optical and industrial sapphire products in a variety of shapes and sizes, including round and rectangular windows, blanks, domes, tubes and rods.
Historically, we have also provided sapphire products to the LED and mobile device markets, which are the largest markets for sapphire. However, given competitive pressures in those markets, in the fourth quarter of 2016 we announced our decision to focus on the optical and industrial sapphire markets and exit the LED market. Following this decision, we closed our Malaysia facility and scaled down and consolidated our remaining operations in the U.S. In the succeeding years we have completed individual sales and held auctions for assets located in Malaysia and at each of our U.S. properties, resulting in the sale of certain of our excess equipment and consumable assets. In December 2019 we entered into a purchase and sale agreement to sell our manufacturing facility located in Malaysia and it was completed in June 2020. In December 2020, Rubicon sold all of the outstanding shares of capital stock of its wholly owned subsidiary Rubicon Sapphire Technology (Malaysia) SDN BHD.
We manage our operations and ship from our owned facility located in Bensenville, Illinois.
Our sapphire business operates in a very competitive market. Our ability to expand our optical and industrial business and the acceptance of new product offerings are difficult to predict. Our total sales backlog was approximately $1,735,000 and $747,000 as of December 31, 2021 and 2020, respectively.
In June 2021 the operations of Direct Dose Rx were discontinued. The costs associated with such closure were not material. Direct Dose Rx was a specialized pharmacy that provided prescription medications, over-the-counter drugs and vitamins to patients being discharged from skilled nursing facilities and hospitals and directly to retail customers who want such medications delivered to their home. The delivered products were sorted by the dose, date and time to be taken and come in easy to use perforated strip-packaging as opposed to separate pill bottles. Direct Dose Rx was licensed to operate in 11 states. The services offered by Direct Dose Rx benefited patients, skilled nursing facilities and hospitals by reducing the risk of hospital readmissions.
Rubicon is actively evaluating the acquisition of profitable companies in order to utilize our substantial net operating loss (“NOL”) tax carryforwards.
Rubicon Technology, Inc. is a Delaware corporation and was incorporated on February 7, 2001. Our common stock is listed on the NASDAQ Capital Market under the ticker symbol “RBCN.”
Sapphire INDUSTRY OVERVIEW
Sapphire is utilized in optical and industrial applications. It is used for windows and optics for aerospace, sensor, medical, semiconductor, instrumentation, electronics and laser applications due to its wide-band transmission, superior strength, chemical and scratch resistance and high strength-to-weight ratio.
PRODUCTS
We provide optical and industrial sapphire products in various shapes and sizes, including round and rectangular windows and blanks, domes, tubes and rods. These optical sapphire products are qualified and used in equipment for a wide variety of end markets and high performance applications, including defense and aerospace, specialty lighting, instrumentation, sensors and detectors, semiconductor process equipment, electronic substrates, medical and laser applications.
RESEARCH AND DEVELOPMENT
In 2021 and 2020, Rubicon did not incur any research and development (“R&D”) expenses and it currently does not have any plans for expenditures in 2022 related to R&D.
SALES AND MARKETING
We market and sell through our direct sales force to customers. Our direct sales team includes experienced and technically sophisticated sales professionals and engineers who are knowledgeable in the development, manufacturing and use of sapphire windows and other optical materials.
A key component of our marketing strategy is developing and maintaining strong relationships with our customers. We achieve this by working closely with our customers to optimize our products for their production processes. We believe that maintaining close relationships with our customers’ senior management and providing technical support improves customer satisfaction.
CUSTOMERS
Our principal customers have been defense subcontractors, industrial manufacturers, fabricators and resellers. A substantial portion of our sales have been to a small number of customers. In 2021, our top three customers (each 10% or greater of our revenues) accounted for, in the aggregate, approximately 46% of our revenue from our continuing operations and in 2020, the top four customers accounted for approximately 55% of our revenue from our continuing operations. Although we are attempting to diversify and expand our customer base, we expect our sales to continue to be concentrated among a small number of customers. However, we also expect that our significant customers may change from time to time. No other customer accounted for 10% or more of our sapphire revenues during 2021 or 2020 other than those referred to above.
INTELLECTUAL PROPERTY
We rely primarily upon a combination of know-how, patents, trade secret laws and non-disclosure agreements with employees, customers and potential customers to protect our intellectual property. However, we believe that factors such as the technological and innovative abilities of our personnel, the success of our ongoing product development efforts and our efforts to maintain trade secret protection are more important than patents in maintaining our competitive position.
COMPETITION
The markets for high-quality sapphire products are very competitive and have been characterized by rapid technological change. The products we sell must meet certain demanding requirements to succeed in the marketplace. Although we are a well-established sapphire provider, we face significant competition from other established providers of similar products as well as from new and potential entrants into our markets.
ENVIRONMENTAL REGULATION
In our manufacturing process, we use water, oils, slurries, acids, adhesives and other industrial chemicals. We are subject to a variety of federal, state and local laws regulating the discharge of these materials into the environment or otherwise relating to the protection of the environment. These include statutory and regulatory provisions under which we are responsible for the management of hazardous materials we use and the disposition of hazardous wastes resulting from our manufacturing processes. Failure to comply with such provisions, whether intentional or inadvertent, could result in fines and other liabilities to the government or third parties, injunctions requiring us to suspend or curtail operations or other remedies, which could have a material adverse effect on our business. The cost of complying with environmental regulation is not material.
EMPLOYEES
As of December 31, 2021, we had 13 full-time employees. None of our employees are represented by a labor union. We consider our employee relations to be good.

ITEM 1A. RISK FACTORS
ITEM 1A. RISK FACTORS
You should carefully read the risk factors set forth below, together with the financial statements, related notes and other information contained in this Annual Report on Form 10-K. Our business is subject to a number of important risks and uncertainties, some of which are described below. The risks described below, however, are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also impair our business operations. Any of these risks may have a material adverse effect on our business, financial condition, results of operations and cash flows. Please refer to the discussion of “forward-looking statements” on page one of this Annual Report on Form 10-K in connection with your consideration of the risk factors and other important factors that may affect future results described below.
We have incurred significant losses in prior periods and may incur losses in the future.
We have incurred significant losses in prior periods and may incur significant losses in the future. These losses may have an adverse effect on our ability to attract new customers or retain existing customers. We have incurred net losses of $0.7 million, $1.1 million, $1.1 million, $17.8 million and $62.9 million in 2021, 2020, 2019, 2017 and 2016, respectively. Although we recorded net income of $963,000 in 2018, there can be no assurance that we will achieve profitability in future periods.
We are exploring, evaluating and have begun implementing certain strategic alternatives with a goal of providing greater value to our stockholders. There can be no assurance that we will be successful in identifying additional strategic alternatives or implementing any strategic alternative, or that any strategic alternative will yield additional value for stockholders.
Our management and Board of Directors are continuing to review strategic alternatives with a goal of providing greater value to our stockholders. These alternatives could result in, among other things, modifying or eliminating certain of our operations, selling material assets, seeking additional financing, selling the business, making investments, effecting a merger, consolidation or other business combination, partnering or other collaboration agreements, or potential acquisitions or recapitalizations, in one or more transactions.
There can be no assurance that our continued exploration of strategic alternatives will result in the identification of additional alternatives or that any transaction will be consummated. The process of exploring strategic alternatives may be costly and may be time consuming, distracting to management and disruptive to our business operations. If we are unable to effectively manage the process, our business, financial condition and results of operations could be adversely affected. We also cannot provide assurance that any potential transaction, investment or other alternative identified, evaluated and consummated, will provide greater value to our stockholders than that reflected in the current stock price. Any potential transaction or investment would be dependent upon a number of factors that may be beyond our control, including, among other factors, market conditions, industry trends and the availability of financing to us on reasonable terms.
We may acquire other businesses, products or technologies; if we do, we may be unable to integrate them with our business effectively or at all, which may adversely affect our business, financial condition and operating results.
If we find appropriate opportunities and have adequate funding, we may acquire other businesses, product lines or technologies. However, if we acquire a business, product line or technology, the process of integration may produce unforeseen operating difficulties and expenditures and may absorb significant attention of our management that would otherwise be available for the ongoing development of our business. Further, the acquisition of a business may result in the assumption of unknown liabilities or create risks with respect to our existing relationships with suppliers and customers. If we make acquisitions, we may issue shares of stock that dilute other stockholders, expend cash, incur debt, assume contingent liabilities or create additional expenses related to amortizing intangible assets, any of which may adversely affect our business, financial condition or operating results.
If we are unable to raise additional capital when needed, we may not be able to execute the acquisition of other businesses.
We may require additional capital to fund operations, capital expenditures and or the acquisition of other businesses. We may finance future cash needs through public or private equity offerings, debt financings, corporate collaborations or licensing arrangements. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate one or more of our acquisition opportunities. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through corporate collaborations or licensing arrangements, it may be necessary to relinquish some rights to our technologies or our new products, or grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.
We believe our existing cash, cash equivalents and short-term investments and interest thereon, will be sufficient to fund our projected operating requirements for at least the next twelve months. However, if our success in generating sufficient operating cash flow or our use of cash in the next twelve months were to significantly adversely change, we may not have enough funds available to continue operating at our current level in future periods. A limitation of funds available may raise concerns about our ability to continue to operate. Such concerns may limit our ability to obtain financing and some customers may not be willing to do business with us.
Rubicon Technology Worldwide
We rely on third parties for certain material and finishing steps for our products, including the slicing and polishing of our sapphire crystal.
In order to reduce product costs and improve cash flow, we use third parties for certain material and finishing functions for our products, including the slicing and polishing of our sapphire crystal inventory. These types of services are only available from a limited number of third parties. Our ability to successfully outsource these finishing functions will substantially depend on our ability to develop, maintain and expand our strategic relationship with these third parties. Any impairment in our relationships with the third parties performing these functions, in the absence of a timely and satisfactory alternative arrangement, could have a material adverse effect on our business, results of operations, cash flow and financial condition. In addition, we do not control any of these third parties or the operation of their facilities, and we may not be able to adequately manage and oversee the third parties performing our finishing functions. Accordingly, any difficulties encountered by these third parties that result in product defects, delays or defaults on their contractual commitments to us could adversely affect our business, financial condition and results of operations. In addition, their facilities may be vulnerable to damage or interruption from natural disasters, inclement weather conditions, power loss, acts of terrorism and similar events. A decision to close a facility without adequate notice as a result of these or other unanticipated problems at the facility could result in lengthy interruptions in their services to us; and any loss or interruption of these services could significantly increase our expenses, cause us to default on our obligations to our customers and/or otherwise adversely affect our business. Furthermore, the outsourcing of our finishing steps, such as slicing and polishing of wafers, may not continue to be available at reasonable prices or on commercially reasonable terms, or at all.
Our gross margins could fluctuate as a result of changes in our product mix and other factors, which may adversely impact our operating results.
We anticipate that our gross margins will fluctuate from period to period as a result of the mix of products that we sell in any given period. We are working to increase sales of higher margin products, introduce new differentiated products and lower our costs. There can be no assurance that we will be successful in improving our gross margin mix. If we are not successful, our overall gross margin levels and operating results in future periods would continue to be adversely impacted. Increased competition and the adoption of alternatives to our products, more complex engineering requirements, lower demand and other factors may lead to a further downward shift in our product margins, leading to price erosion and lower revenues for us in the future.
The markets in which we operate are very competitive, and many of our competitors and potential competitors are larger, more established and better capitalized than we are.
The markets for selling high-quality sapphire products are very competitive and have been characterized by rapid technological change. This competition could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses, and failure to increase, or the loss of, market share or expected market share, any of which would likely seriously harm our business, operating results and financial condition.
The average selling prices of sapphire products have historically been volatile and in recent years sapphire product prices have been increasingly depressed.
Historically, our industry has experienced volatility in product demand and pricing. However, in the last five years, the sales prices for our sapphire products have trended downward due to an over-supply of products in the market. In some countries, government programs support sapphire producers who would otherwise be unprofitable; in such circumstances, sapphire may be sold at prices below cost for an extended period of time, depressing market prices, to the detriment of our gross margins. This has had a significant adverse impact on our profitability and our results of operations. Moreover, changes in average selling prices of our products as a result of competitive pricing pressures increased sales discounts and new product introductions by our competitors could have a significant impact on our profitability. Although we attempt to optimize our product mix, introduce new products, reduce manufacturing costs and pass along certain increases in costs to our customers in order to lessen the effect of decreases in selling prices, we may not be able to successfully do so in a timely manner or at all, and our results of operations and business may be harmed.
Our future operating results may fluctuate significantly, which makes our future results difficult to predict and could cause our operating results for particular periods to fall below expectations.
Our revenues and operating results have fluctuated in the past and are likely to fluctuate in the future. These fluctuations are due to a number of factors, many of which are beyond our control. In connection with the Board of Directors’ continuing review of alternatives with a goal of providing greater value to our stockholders, the Board decided to limit our business focus to the optical and industrial sapphire markets and to exit the LED and mobile device markets. The optical and industrial sapphire markets are smaller markets than our historical undertakings and there is no assurance that we will be able to successfully expand our optical and industrial sapphire business, or that such shift in focus will ultimately improve our profitability or operating results.
We depend on a few customers for a major portion of our sales and our results of operations would be adversely impacted if they reduce their order volumes.
Historically, we have earned, and believe that in the future we will continue to earn, a substantial portion of our revenue from a small number of customers. In 2021, our top three customers accounted for, in the aggregate, approximately 46% of our revenue from our continuing operations, and in 2020, our top four customers accounted for approximately 55% of our revenue from our continuing operations. If we were to lose one of our major customers or have a major customer significantly reduce its volume of business with us, our revenues and profitability would be materially reduced unless we are able to replace such demand with other orders promptly. We expect to continue to be dependent on our major customers, the number and identity of which may change from period to period.
We generally sell our products on the basis of purchase orders. Thus, most of our customers could cease purchasing our products with little or no notice and without penalties. In addition, delays in product orders could cause our quarterly revenue to vary significantly. A number of factors could cause our customers to cancel or defer orders, including interruptions to their operations due to a downturn in their industries, natural disasters, delays in manufacturing their own product offerings into which our products are incorporated, securing other sources for the products that we manufacture or developing such products internally.
If we are unable to attract or retain qualified personnel, our business could be harmed.
Our success depends on our continued ability to identify, attract, hire, train, retain and motivate highly skilled technical, managerial, manufacturing, administrative and sales and marketing personnel. Competition for these individuals is intense, and we may not be able to successfully recruit, assimilate or retain sufficiently qualified personnel. In particular, we may encounter difficulties in recruiting and retaining a sufficient number of qualified personnel. The inability to attract and retain necessary technical, managerial, manufacturing, administrative and sales and marketing personnel could harm our ability to obtain new customers and develop new products and could adversely affect our business and operating results. In addition, the loss of the services, or distraction, of our senior management for any reason could adversely affect our business, operating results and financial condition.
We are dependent on the continued services and performances of certain senior management employees such as sales management and the head of operations.
Our future success is dependent on the continued services and contributions of our senior management who must work together effectively in order to design and produce our products, expand our business, increase our revenue and improve our operating results. The loss of services of our senior management for any reason could adversely affect our business, operating results and financial condition.
Our gross margins and profitability may be adversely affected by energy costs.
All of our power consumption takes place in our manufacturing facility in the United States. Electricity prices could increase due to overall changes to the price of energy due to conditions in the Middle East, natural gas shortages in the U.S. and other economic conditions and uncertainties regarding the outcome and implications of such events. If electricity prices increase significantly, we may not be able to pass these price increases through to our customers on a timely basis, if at all, which could adversely affect our gross margins and results of operations.
The protection of our intellectual property rights and the defense of claims of infringement against us by third parties may subject us to costly litigation.
Other companies might allege that we are infringing certain of their patents or other rights. If we are unable to resolve these matters satisfactorily, or to obtain licenses on acceptable terms, we may face litigation. Any litigation to enforce patents issued to us, to protect trade secrets or know-how possessed by us or to defend us or indemnify others against claimed infringement of the rights of others could have a material adverse effect on our financial condition and operating results. Regardless of the validity or successful outcome of any such intellectual property claims, we may need to expend significant time and expense to protect our intellectual property rights or to defend against claims of infringement by third parties, which could have a material adverse effect on us. If we lose any such litigation where we are alleged to infringe the rights of others, we may be required to:
● pay substantial damages;
● seek licenses from others; or
● change, or stop manufacturing or selling, some or all of our products.
Any of these outcomes could have an adverse effect on our business, results of operations or financial condition.
We are subject to numerous environmental laws and regulations, which could expose us to environmental liabilities, increase our manufacturing and related compliance costs or otherwise adversely affect our business and operating results.
In our manufacturing process, we use water, oils, slurries, acids, adhesives and other industrial chemicals. We are subject to a variety of foreign, federal, state and local laws and regulations governing the protection of the environment. These environmental laws and regulations include those relating to the use, storage, handling, discharge, emission, disposal and reporting of toxic, volatile or otherwise hazardous materials used in our manufacturing processes. These materials may have been or could be released into the environment at properties currently or previously operated by us, at other locations during the transport of the materials, or at properties to which we send substances for treatment or disposal. If we were to violate or become liable under environmental laws and regulations or become non-compliant with permits required at some of our facilities, we could be held financially responsible and incur substantial costs, including investigation and cleanup costs, fines and civil or criminal sanctions, third-party property damages or personal injury claims. In addition, new laws and regulations or stricter enforcement of existing laws and regulations could give rise to additional compliance costs and liabilities.
RTW’s operations are concentrated in one facility, and the unavailability of this facility could harm our business.
Our manufacturing, research and development, sales and marketing, and administrative activities are concentrated in one facility located in Bensenville, Illinois. Going forward, this will be RTW’s sole operating facility. Should a casualty, natural disaster, inclement weather, an outbreak of disease, power loss, an act of terrorism or similar event affect the Chicagoland area, our operations could be significantly impacted. We may not be able to replicate the manufacturing capacity and other operations of our Bensenville facility or such replication could take significant time and resources to accomplish. The disruption from such an event could adversely affect or interrupt entirely our ability to conduct our business.
We are dependent on information technology, and disruptions, failures or security breaches of our information technology infrastructure could have a material adverse effect on our operations. In addition, increased information technology security threats and more sophisticated computer crime pose a risk to our systems, networks, products and services.
We rely on information technology networks and systems, including the Internet and cloud services, many of which are managed by third parties, to securely process, transmit and store electronic information of financial, marketing, legal and regulatory nature to manage our business processes and activities. Although we have implemented enhanced controls around our information technology systems, these systems may be susceptible to damage, disruptions or shutdowns due to failures during the process of upgrading or replacing software, databases, power outages, hardware failures, telecommunication failures, user errors, natural disasters, terrorist attacks or other catastrophic events. If any of our significant information technology systems suffer severe damage, disruption or shutdown, and our disaster recovery and business continuity plans do not effectively resolve the issues in a timely manner, our product sales, financial condition and results of operations may be materially and adversely affected, and we could experience delays in reporting our financial results, or our operations may be disrupted, exposing us to performance failures with customers. In addition, cybersecurity threats, such as computer viruses, attacks by computer hackers or other cybersecurity threats pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data. There can be no assurance that our security controls and safeguard measures taken to improve our cybersecurity protection will be sufficient to mitigate all potential risks to our systems, networks and data. Potential consequences of a cybersecurity attack include disruption to systems, corruption of data, unauthorized release of confidential or otherwise protected information, reputational damage, and litigation with third parties. The amount of insurance coverage we maintain may be inadequate to cover claims or liabilities related to a cybersecurity attack.
Our U.S. NOL carryforwards may expire or could be substantially limited if we experience an ownership change as defined in the Internal Revenue Code (“IRC”) or if changes are made to the IRC.
We have significant U.S. NOL carryforwards. Under federal tax laws, we can carry forward and use our NOLs to reduce our future U.S. taxable income and tax liabilities until such NOL carryforwards expire in accordance with the IRC of 1986, as amended. Our NOL carryforwards provide a benefit to us, if fully utilized, of significant future tax savings. However, our ability to use these tax benefits in future years will depend upon the amount of our federal and state taxable income. If we do not have sufficient federal and state income in future years to use the benefits before they expire, we will permanently lose the benefit of the NOL carryforwards. Our ability to use the tax benefits associated with our NOL carryforwards is dependent upon our generation of future taxable profits and our ability to successfully identify and consummate suitable acquisitions or investment opportunities.
Additionally, Section 382 and Section 383 of the IRC provide an annual limitation on our ability to utilize our NOL carryforwards, as well as certain built-in losses, against the future U.S. taxable income in the event of a change in ownership, as defined under the IRC. While we have implemented a stockholder’s right plan to protect our NOL carryforwards, there is no assurance that we will not experience a change in ownership in the future as a result of changes in our stock ownership, and any such subsequent changes in ownership for purposes of the IRC could further limit our ability to use our NOL carryforwards.
Under the recently enacted Tax Cut and Jobs Act, U.S. NOLs generated on or after January 1, 2018, could be limited to 80% of taxable income. If other changes were made to the IRC, they could impact our ability to utilize our NOLs. Accordingly, any such occurrences could adversely affect our financial condition, operating results and cash flows.
The Company’s business, results of operations, financial condition and stock price have been adversely affected and could in the future be materially adversely affected by the COVID-19 pandemic.
COVID-19 has spread rapidly throughout the world, prompting governments and businesses to take unprecedented measures in response. Such measures have included restrictions on travel and business operations, temporary closures of businesses, and quarantines and shelter-in-place orders. The COVID-19 pandemic has significantly curtailed global economic activity and caused significant volatility and disruption in global financial markets. The Company maintains a limited staff of full-time employees in skilled technical, non-technical and key management positions. If employees become infected by the COVID-19 virus we may not be able to maintain normal business operations for an extended period of time.
The COVID-19 pandemic and the measures taken by many countries in response have adversely affected and could in the future materially adversely impact the Company’s business, results of operations, financial condition and stock price. Following the initial outbreak of the virus, the Company experienced disruptions to its manufacturing, supply chain and logistical services provided by outsourcing partners, resulting in temporary supply shortages that affected sales worldwide. The Company is heavily reliant on domestic and foreign supply chains to operate its businesses. The COVID-19 pandemic may limit and restrict our access to necessary products that are required to operate.
The Company is continuing to monitor the situation and take appropriate actions in accordance with the recommendations and requirements of relevant authorities. The full extent of the impact of the COVID-19 pandemic on the Company’s operational and financial performance is currently uncertain and will depend on many factors outside the Company’s control, including, without limitation, the timing, extent, trajectory and duration of the pandemic, the development and availability of effective treatments and vaccines, the imposition of and compliance with protective public safety measures, and the impact of the pandemic on the global economy and demand for consumer products. Additional future impacts on the Company may include, but are not limited to, material adverse effects on: demand for the Company’s products and services; the Company’s supply chain and sales and distribution channels; the Company’s ability to execute its strategic plans; and the Company’s profitability and cost structure.
To the extent the COVID-19 pandemic adversely affects the Company’s business, results of operations, financial condition and stock price, it may also have the effect of heightening many of the other risks described in this Part I, Item 1A of this Form 10-K.
RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK
The trading price of our common stock has been and will likely continue to be volatile due to various factors, some of which are beyond our control, and each of which could adversely affect our stockholders’ value.
Factors related to our Company and our business, as well as broad market and industry factors, may adversely affect the market price of our common stock, regardless of our actual operating performance. Such factors that could cause fluctuations in our stock price include, among other things:
● changes in financial guidance or estimates by us, by investors or by any financial analysts who might cover our stock or our industry;
● our ability to meet the performance expectations of financial analysts or investors;
● general market and economic conditions; and
● the size of the public float of our stock.
Our certificate of incorporation, bylaws and Delaware law may discourage takeovers and business combinations that our stockholders might consider in their best interests.
A number of provisions in our certificate of incorporation and bylaws, as well as anti-takeover provisions of Delaware law, may have the effect of delaying, deterring, preventing or rendering more difficult a change in control of Rubicon that our stockholders might consider in their best interests. These provisions include:
● a classified Board of Directors;
● a tax benefits preservation plan designed to preserve our ability to utilize our net operating losses as a result of certain stock ownership changes, which may have the effect of discouraging transactions involving an actual or potential change in our ownership;
● granting to the Board of Directors sole power to set the number of directors and to fill any vacancy on the Board of Directors, whether such vacancy occurs as a result of an increase in the number of directors or otherwise;
● limitations on the ability of stockholders to remove directors;
● the ability of our Board of Directors to designate and issue one or more series of preferred stock without stockholder approval, the terms of which may be determined at the sole discretion of the Board of Directors;
● prohibition on stockholders from calling special meetings of stockholders;
● prohibition on stockholders from acting by written consent; and
● establishment of advance notice requirements for stockholder proposals and nominations for election to the Board of Directors at stockholder meetings.
These provisions may prevent our stockholders from receiving the benefit from any premium to the market price of our common stock offered by a bidder in a takeover context. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of our common stock if they are viewed as discouraging takeover attempts in the future.
The foregoing provisions of our certificate of incorporation and bylaws may also make it difficult for stockholders to replace or remove our management. These provisions may facilitate management entrenchment that may delay, deter, render more difficult or prevent a change in our control, which may not be in the best interests of our stockholders.
We are subject to litigation risks, including securities class action litigation, which may be costly to defend.
All industries, including ours, are subject to legal claims, including securities litigation. When the market price of a stock declines significantly, due to factors such as trends in the stock market in general, broad market and industry fluctuations or operating performance, holders of that stock have sometimes instituted securities class action litigation against the company that issued the stock. This sort of litigation can be particularly costly and may divert the attention of our management and our resources in general. We have been subject to securities class action litigation in the past, as disclosed in our previous filings with the SEC. Due to the inherent uncertainty of the litigation process, the resolution of any particular legal claim or proceeding (including by settlement) could have a material effect on our business, financial condition, results of operations or cash flows. Further, uncertainties resulting from the initiation and continuation of securities or other litigation could harm our ability to obtain credit and financing for our operations and to compete in the marketplace.
Our Board of Directors does not intend to declare or pay any dividends to our stockholders in the foreseeable future.
The declaration, payment and amount of any future dividends will be made at the discretion of our Board of Directors and will depend upon, among other things, the results of our operations, cash flows and financial condition, operating and capital requirements, and other factors the Board of Directors considers relevant. There is no plan to pay dividends in the foreseeable future, and if dividends are paid, there can be no assurance with respect to the amount of any such dividend.

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 together with our financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. You should review the “Risk Factors” section of this Annual Report for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements described in the following discussion and analysis.
OVERVIEW
Rubicon Technology, Inc. (“Rubicon” or the “Company”) currently consists of one operating subsidiary, Rubicon Technology Worldwide LLC (“RTW”). In June 2021 the operations of Rubicon DTP LLC (“Direct Dose Rx” or DDRX”) were discontinued.
RTW is an advanced materials provider specializing in monocrystalline sapphire for applications in optical and industrial systems. Sapphire is a desirable material for high-performance applications due to its hardness and strength, transparency in the visible and infrared spectrum, thermal conductivity, thermal shock resistance, abrasion resistance, high melting point and chemical inertness. As a result, it is ideally suited for extreme environments in a range of industries where material durability is just as important as optical clarity. We believe that we continue to have a reputation as one of the highest quality sapphire sources in the market. We provide optical and industrial sapphire products in a variety of shapes and sizes, including round and rectangular windows, blanks, domes, tubes and rods.
Historically, we have also provided sapphire products to the LED and mobile device markets, which are the largest markets for sapphire. However, given competitive pressures in those markets, in the fourth quarter of 2016 we announced our decision to focus on the optical and industrial sapphire markets and exit the LED market. Following this decision, we closed our Malaysia facility and scaled down and consolidated our remaining operations in the U.S. In the succeeding years we have completed individual sales and held auctions for assets located in Malaysia and at each of our U.S. properties, resulting in the sale of certain of our excess equipment and consumable assets. In December 2019 we entered into a purchase and sale agreement to sell our manufacturing facility located in Malaysia. In June 2020, the Company completed the sale of its Malaysian facility for net proceeds of approximately $4,800,000 after the payment of consent fees, real estate taxes, brokerage and legal fees, transfer and other expenses. The Company recorded a gain on the disposal of the Malaysian facility of approximately $1,800,000. In December 2020, Rubicon sold all of the outstanding shares of capital stock of its wholly owned subsidiary Rubicon Sapphire Technology (Malaysia) SDN BHD. The Company recorded a gain on the sale of $261,000. In February 2022, we entered into a real estate sale contract to sell our parcel of land in Batavia, Illinois (see Footnote 13). The closing of the sale of the Property is subject to certain conditions precedent. There is currently no anticipated closing date.
We manage our operations and ship from our owned facility located in Bensenville, Illinois.
Our sapphire business operates in a very competitive market. Our ability to expand our optical and industrial business and the acceptance of new product offerings are difficult to predict. Our total sales backlog was approximately $1,735,000 and $747,000 as of December 31, 2021 and 2020, respectively.
In June 2021 the operations of Direct Dose Rx were discontinued. The costs associated with such closure were not material. Direct Dose Rx was a specialized pharmacy that provided prescription medications, over-the-counter drugs and vitamins to patients being discharged from skilled nursing facilities and hospitals and directly to retail customers who want such medications delivered to their home. The delivered products were sorted by the dose, date, and time to be taken, and came in easy-to-use, perforated strip-packaging as opposed to separate pill bottles. Direct Dose Rx was licensed to operate in 11 states. The services offered by Direct Dose Rx benefited patients, skilled nursing facilities and hospitals by reducing the risk of hospital readmissions.
Rubicon is actively evaluating the acquisition of profitable companies in order to utilize our substantial net operating loss (“NOL”) tax carryforwards.
Rubicon Technology, Inc. is a Delaware corporation and was incorporated on February 7, 2001. Our common stock is listed on the NASDAQ Capital Market under the ticker symbol “RBCN.”
Historically, we have earned, and believe that in the future we will continue to earn, a substantial portion of our revenue from a small number of customers. For the year ended December 31, 2021, we had three customers individually that accounted for approximately 22%, 12%, and 12% of our revenue from our continuing operations. For the year ended December 31, 2020, we had four customers individually that accounted for approximately 21%, 13%, 11%, and 10% of our revenue from our continuing operations. Our principal customers have been defense subcontractors, industrial manufacturers, fabricators and resellers. Although we are attempting to diversify and expand our customer base, we expect our sales to continue to be concentrated among a small number of customers. However, we also expect that our significant customers may change from time to time. No other customer accounted for 10% or more of our revenues from our continuing operations during the years ended December 31, 2021 and 2020 other than those referred to above.
We sell our products on a global basis and historically derived a significant portion of our revenue from customers outside of North America, with the majority of our sales to the Asian and European markets. Following the decision to limit our focus to the optical and industrial sapphire markets, a major source of our revenue is derived from the North American market. For the year ended December 31, 2021, the North American and other markets accounted for 90% and 10% of our revenue, respectively. For the year ended December 31, 2020, the North American and other markets accounted for 88% and 12% of our revenue of continuing operations, respectively. All our revenue and corresponding accounts receivable are denominated in U.S. dollars. For more information about our revenues by geographic region, see Note 2 - Segment Information of our Consolidated Financial Statements included in this Annual Report on Form 10-K.
Financial operations
Revenue. RTW’s revenue consists of sales of optical and industrial sapphire products sold as blanks or polished windows. Products are made to varying specifications, such as crystal planar orientations and thicknesses. With the focus on smaller optical and industrial markets and the consolidation of our operations in the U.S., we expect in future periods our revenue will continue to be primarily from the sale of optical materials. We recognize revenue once the performance obligation is satisfied, when the product is manufactured to the customer’s specification and based upon shipping terms, title, and control of the product and risk of loss transfer to the customer. Delays in product orders or changes to the timing of shipments could cause our quarterly revenue to vary significantly. All of our revenue and corresponding accounts receivable are denominated in U.S. dollars. Substantially all our revenue is generated by our direct sales team and we expect this to continue in the future.
Cost of goods sold. Our cost of goods sold consists primarily of manufacturing materials, labor, manufacturing related overhead such as utilities, depreciation, rent, provisions for excess and obsolete inventory reserves, idle plant charges, outsourcing costs, freight and warranties. We purchase materials and supplies to support current and future demand for our products. We are subject to variations in the cost of consumable assets from period to period because we do not have long-term fixed-price agreements with our suppliers. We currently outsource some of our production processes and needs.
Gross profit (loss). Our gross profit (loss) has been and will continue to be affected by a variety of factors, including average sales prices of our products, product mix, our ability to reduce manufacturing costs, idle plant charges and fluctuations in the costs of electricity, production supplies and other manufacturing overhead costs.
General and administrative expenses. General and administrative expenses (“G&A”) consist primarily of compensation and associated costs for employees in finance, information technology and administrative activities, charges for accounting, legal services, insurance and stock-based compensation.
Sales and marketing expenses. Sales and marketing expenses consist primarily of salaries and associated costs for employees engaged in sales activities, product samples, charges for participation in trade shows and travel.
(Gain) loss on sale or disposal of assets. (Gain) loss on sale or disposal of assets represents the difference between the amount of proceeds from sale of our property, equipment and consumable assets and their respective net book values. When the amount of proceeds exceeds the net book value of an underlying asset, we record this favorable variance as a gain on sale or disposal of assets. Alternatively, when the net book value of an asset exceeds the amount of proceeds recovered from sale or disposal of this asset, such unfavorable variance is recorded as a loss on sale or disposal of assets.
Other income (expense). Other income (expense) consists of interest income, gains and losses on investments, and currency translation.
Provision for income tax. We account for income taxes under the asset and liability method whereby the expected future tax consequences of temporary differences between the book value and the tax basis of assets and liabilities are recognized as deferred tax assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to be recognized. Our analysis of ownership changes that limit the utilization of our NOL carryforwards as of December 31, 2021, shows no impact on such utilization. We are in a cumulative loss position for the past three years which is considered significant negative evidence that is difficult to overcome on a “more likely than not” standard through objectively verifiable data. Based on an evaluation in accordance with the accounting standards, as of December 31, 2021 and 2020, a valuation allowance has been recorded against the net U.S. and Malaysia deferred tax assets in order to measure only the portion of the deferred tax assets that are more likely than not to be realized based on the weight of all the available evidence. Until an appropriate level of sustained profitability is attained, we expect to maintain a full valuation allowance on our U.S. and Malaysia net deferred tax assets. Any U.S. and Malaysia tax benefits or tax expense recorded on the Consolidated Statement of Operations will be offset with the corresponding adjustment from the use of the NOL carryforward asset which currently has a full valuation allowance. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.
Stock-based compensation. The majority of our stock-based compensation relates primarily to our Board of Directors, executive and administrative personnel and is accounted for as a G&A expense. For the years ended December 31, 2021 and 2020, our stock-based compensation expense was $371,000 and $199,000, respectively.

Comparison of years ended December 31, 2021 and 2020
Revenue. Revenue from continuing operations was $4,061,000 for the year ended December 31, 2021, and $3,616,000 for the year ended December 31, 2020, an increase of $445,000. This increase was due to an increase in sapphire sales. These sales are impacted by demand fluctuations as well as the timing of purchase orders and shipments.
Revenue from discontinued operations was $370,000 and $851,000 for the years ended December 31, 2021 and 2020, respectively. This decrease of $481,000 was primarily due to the discontinuation of operations in June 2021.
Gross profit (loss). Gross profit from continuing operations was $1,263,000 for the year ended December 31, 2021 and $1,008,000 for the year ended December 31, 2020, an increase of $255,000. The gross profit increase was due to the increase in revenue and efficiencies achieved by outsourcing various aspects of our production processes.
Gross profit from discontinued operations was $33,000 and $233,000, for the years ended December 31, 2021 and 2020, respectively. This decrease of $200,000 was due primarily to increased inventory cost and decreased reimbursement rates from plan benefit managers, as well as the discontinuation of operations.
General and administrative expenses. General and administrative expenses from continuing operations were $2,130,000 and $1,942,000 for the years ended December 31, 2021 and 2020 respectively, an increase of $188,000 which was primarily due to an increase in legal, audit, and other consulting fees of $87,000, an increase in insurance expense of $54,000, and an increase in employee compensation of $87,000, offset by a decrease in other administrative costs of $46,000.
General and administrative expenses from discontinued operations were $285,000 and $528,000 for the years ended December 31, 2021 and 2020, respectively. This decrease of $243,000 was primarily attributable to a reduction in personnel expenses and the winding down of operations.
Sales and marketing expenses. Sales and marketing expenses from continuing operations were $210,000 and $280,000 for the years ended December 31, 2021 and 2020, respectively, a decrease of $70,000. This was primarily due to a decrease in staffing.
Sales and marketing expenses from discontinued operations were $10,000 and $45,000, for the years ended December 31, 2021 and 2020, respectively. This decrease of $35,000 was primarily due to a decrease in staffing and the discontinuation of operations.
(Gain) loss on sale or disposal of assets. During 2021, the Company recorded a gain of $613,000 from the sale of excess equipment and consumable assets of continuing operations.
In June 2020, the Company completed the sale of its Malaysian facility resulting in net proceeds of approximately $4,800,000 million after the payment of consent fees, real estate taxes, brokerage and legal fees, transfer and other expenses. The Company recorded a gain on the disposal of the Malaysian facility of approximately $1,800,000. In December 2020, Rubicon sold all of the outstanding shares of capital stock of its wholly owned subsidiary Rubicon Sapphire Technology (Malaysia) SDN BHD for gross proceeds of approximately $775,000. The Company recorded a gain from such stock sale of $261,000.
The Company recorded a loss on the sale of assets from discontinued operations of $9,000 for the year ended December 31, 2021.
Long-lived asset impairment charges. We did not record any additional asset impairment expenses for the years ended December 31, 2021 and December 31, 2020. We will continue to assess our long-lived assets to ensure the carrying amount of these assets is still appropriate given any changes in the asset usage, marketplace and other factors used in determining the current fair value.
Other income (expense). Other income (expense) from continuing operations was $5,000 and $(1,580,000) for the years ended December 31, 2021 and 2020, respectively, an increase of $1,585,000. Other income in 2021 was comprised of interest income of $5,000. Other (expense) in 2020 was comprised of realized (loss) on investments of ($1,824,000) offset by interest income and a gain on foreign currency translation of $108,000 and $136,000, respectively, resulting in the net increase of $1,585,000.
Income tax (expense) benefit. We are subject to income taxes in the United States. On an annual basis, we assess the recoverability of deferred tax assets and the need for a valuation allowance. For the year ended December 31, 2021, a valuation allowance has been included in the 2021 forecasted effective tax rate. At December 31, 2021, we continue to be in a three-year cumulative loss position; therefore, as of December 31, 2021, we maintained a full valuation allowance on our United States net deferred tax assets and until an appropriate level of profitability is attained, we expect to maintain a full valuation allowance going forward. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.
On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Act”) which, among other provisions, reduced the U.S. corporate tax rate from 35% to 21% effective January 1, 2018. The SEC issued guidance, Staff Accounting Bulletin 118, on accounting for the tax effects of the Act. The guidance allowed us to record provisional amounts for those impacts, with the requirement that the accounting be completed in a period not to exceed one year from the date of enactment. We have completed our accounting for the tax effects of the enactment of the Act. The deemed inclusion from the repatriation tax was $5.0 million at the time the calculation was finalized for the tax return. As we are in a full valuation allowance position (as described above), an equal benefit adjustment was recorded for the impact of the increase of the deemed repatriation tax. The tax provision for the years ended December 31, 2021 and 2020 is based on an estimated combined statutory effective tax rate. For the years ended December 31, 2021 and 2020, we recorded a tax expense of $0 and $13,000, respectively, for an effective tax rate of 0.0% and 1.0%, respectively. For the years ended December 31, 2021 and 2020, the difference between our effective tax rate and the U.S. federal 21% statutory rate and state 7.4% (net of federal benefit) statutory rate was primarily related to the change in our U.S. and Malaysia NOL valuation allowances, U.S. R&D credit, Malaysia foreign tax rate differential and Malaysia withholding taxes.
At December 31, 2021, we had separate Federal, Illinois and Indiana NOL carryforwards of $189 million, $181 million, and $655,000, respectively. The Federal and Illinois NOLs began to expire in 2021 and the Indiana NOL will begin to expire in 2039. With the adoption of ASU 2016-09 in 2017, we recorded a deferred tax asset related to $26,400,000 of unrecorded Federal and State NOLs attributable to stock option exercises. NOLs attributable to the stock option exercise were fully offset by the valuation allowance (as described above). We have recorded an uncertain tax position of $2,600,000 that further reduces the net operating loss deferred tax assets reported in the financial statements. In addition, at December 31, 2021, we had Federal research and development credits of $662,000, which will begin to expire in 2028.
LIQUIDITY AND CAPITAL RESOURCES
We have historically funded our operations using a combination of issuances of common stock and cash generated from our operations.
As of December 31, 2021, we had cash equivalents and short-term investments totaling $26,011,000, including cash of $8,123,000 held in deposits at major banks, $3,137,000 invested in money market funds and $14,751,000 of short-term investments in U.S. Treasury securities.
We plan to limit our capital expenditures primarily to only those required under existing obligations or as otherwise necessary to realize value from the development, commercialization or sale of products.
Cash used in operating activities of continuing operations was $61,000 for the year ended December 31, 2021. The Company generated a net loss of $459,000, including non-cash items of $102,000, and an increase in cash from a decrease in net working capital of $500,000. The net working capital decrease was primarily driven by a decrease in inventories of $356,000, was a decrease in prepaid assets and other current assets of $108,000, and an increase in accrued payroll of $215,000. Additionally, there was an increase in accounts receivable of $236,000, which was the result of an increase in 3rd party trade receivables of $447,000 offset by a $211,000 decrease in amounts due from Direct Dose Rx.
Cash provided from operating activities of continuing operations was $181,000 for the year ended December 31, 2020. During 2020, there was a net loss of $723,000, including non-cash items of $91,000, and an increase in cash from a decrease in net working capital of $813,000. The net working capital decrease was primarily driven by a decrease in accounts receivable of $257,000, which was the result of a decrease in 3rd party trade receivables of $737,000 offset by a $480,000 increase in amounts due from Direct Dose Rx. Additionally, there was a decrease in prepaid expenses and other assets of $199,000 from refunded security deposits and purchases against a vendor credit partially offset by increased insurance premiums, as well as a decrease in accounts payable and accrued liabilities of $401,000 primarily from a $400,000 payment on hold at the end of the prior year.
Cash used in discontinued operations for the year ended December 31, 2021 of $262,000 was primarily the result of a net loss from discontinued operations of $271,000, as well as a decrease in inventories of $59,000 and an increase in accounts payable of $29,000. There was also a decrease in 3rd party trade receivables of $113,000, as well as a decrease in amounts owed to Rubicon of $211,000.
Cash provided by discontinued operations for the year ended December 31, 2020 of $116,000 was primarily the result of a net loss from discontinued operations of $340,000, an increase in accounts payable of $23,000, in addition to an increase in 3rd party trade receivables of $71,000, as well as an increase in amounts owed to Rubicon of $480,000.
Net cash provided from investing activities of continuing operations of $640,000 for the year ended December 31, 2021 was from the sale of excess equipment and consumable assets.
Net cash provided from investing activities of continuing operations was $4,536,000 for the year ended December 31, 2020. This increase in net cash was the result of the sale of the Company’s Malaysian facility for net proceeds of approximately $4,800,000 after the payment of consent fees, real estate taxes, brokerage and legal fees, transfer and other expenses assets, the sale of our Malaysia subsidiary for net proceeds of $744,000, the receipt by the Company of $1,700,000 from the sales of investments, offset by the use of $2,800,000 to purchase U.S. Treasury securities and marketable securities.
Cash flows from financing activities
Net cash used in financing activities of continuing operations was $187,000 for the year ended December 31, 2021, resulting from cash used to settle net equity awards of $187,000.
Net cash used in financing activities of continuing operations was $2,447,000 for the year ended December 31, 2020, driven by purchases of our treasury stock of $2,400,000 and cash used to settle net equity awards of $48,000.
Future liquidity requirements
We believe that our existing cash, cash equivalents, anticipated cash flows from operating activities and proceeds from sales or lease of fixed assets will be sufficient to meet our anticipated cash needs for at least the next twelve months from the date of filing of this report. However, if our ability to generate sufficient operating cash flow or our use of cash in the next twelve months were to significantly adversely change, we may not have enough funds available to continue operating at our current level in future periods. Our cash needs include cash required to fund our operations. If the assumptions underlying our business plan regarding future revenues and expenses change, or if unexpected opportunities or needs arise, we may seek to raise additional cash by selling equity or convertible debt securities. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly issued securities may have rights, preferences or privileges senior to those of existing stockholders.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The preparation of financial statements in accordance with the accounting principles generally accepted in the U.S. requires us to make estimates, assumptions and judgments that affect the amounts reported in our financial statements and the accompanying notes. We base our estimates on historical experience and various other assumptions that we believe to be reasonable. Although these estimates are based on our present best knowledge of the future impact on the Company of current events and actions, actual results may differ from these estimates, assumptions and judgments.
We consider to be critical those accounting policies that require our most subjective or complex judgments, which often result from a need to make estimates about the effect of matters that are inherently uncertain, and that are among the most important of our accounting policies in the portrayal of our financial condition and results of operations. We believe the following to be our critical accounting policies, including the more significant estimates and assumptions used in preparation of our financial statements.
Foreign currency translation and transactions.
We have determined that the functional currency of Rubicon Sapphire Technology (Malaysia) SDN BHD (“RST”), which was sold in December 2020, is the U.S. dollar. RST’s assets and liabilities are translated into U.S. dollars using the re-measurement method. Non-monetary assets are translated at historical exchange rates and monetary assets are translated at exchange rates existing at the respective balance sheet dates. Translation adjustments for RST are included in determining net income (loss) for the period. The results of operations are translated into U.S. dollars at the average exchange rates during the respective period. We record these gains and losses in other income (expense).
Foreign currency transaction gains and losses are generated from the effects of exchange rate changes on transactions denominated in a currency other than our functional currency, which is the U.S. dollar. Gains and losses on foreign currency transactions are generally required to be recognized in the determination of net income (loss) for the period. We record these gains and losses in other income (expense).
Revenue recognition.
We recognize revenue in accordance with ASC Topic 606, Revenue From Contracts with Customers (“Topic 606”) which was adopted on January 1, 2018. We recognize revenue when performance obligations under a purchase order or signed quotation are satisfied. Our business practice commits us to manufacture and deliver product upon acceptance of a customer’s purchase order or signed quotation (“agreement”). The agreement with the customer includes specifications of the product to be delivered, price, expected ship date and payment terms. Our agreements generally do not contain variable, financing, rights of return or non-cash components. There are no up-front costs to develop the production process. The performance obligation is satisfied at the point in time (single performance obligation) when the product is manufactured to the customer’s specification, as performance does not create an asset with an alternative use to us. Accordingly, revenue is recognized when product is shipped, and control of the product, title and risk of loss transfer to a customer. We grant credit terms considering normal collection risk. If there is doubt about collection, full prepayment for the order is required. Any payments received prior to shipment are recorded as deferred revenue and included in Advance Payments in the Consolidated Balance Sheets.
We do not provide maintenance or other services and we do not have sales that involve multiple elements or deliverables.
All of our revenue is denominated in U.S. dollars.
Inventory valuation
We value our inventory at the lower of cost or net realizable value. Net realizable value is determined based on an estimated selling price in the ordinary course of business less reasonably predictable costs of completion and disposal. Raw materials cost is determined using the first-in, first-out method, and work-in-process and finished goods costs are determined on a standard cost basis which includes materials, labor and overhead. We establish inventory reserves when conditions exist that suggest inventory may be in excess of anticipated demand or is obsolete based on customer required specifications. We evaluate the ability to realize the value of our inventory based on a combination of factors, including forecasted sales, estimated current and future market value and changes in customers’ product specifications. For the year ended December 31, 2021, we consumed inventory that had previously been reflected as excess or obsolete and recorded a reduction in the inventory reserve of $159,000 and a reduction to cost of goods sold for the same amount. For the year ended December 31, 2020, we consumed inventory that had previously been reflected as excess or obsolete and recorded a reduction in the inventory reserve of $44,000 and a reduction to cost of goods sold for the same amount. In addition, in 2021 we sold inventory that was valued at the lower of cost or market resulting in a reduction in both the lower of cost or market inventory reserve and cost of goods sold of $27,000. In 2020, we sold inventory that was valued at the lower of cost or market resulting in a reduction in both the lower of cost or market inventory reserve and cost of goods sold of $21,000. The excess and obsolete inventory reserve at December 31, 2021 was $7,749,000 compared to $7,908,000 at December 31, 2020.
We did not record any additional write-downs of consumable inventories for the years ended December 31, 2021 and 2020.
We did not record any additional adjustments of raw materials for the year ended December 31, 2021 and 2020, as we sold some of such raw materials at a price exceeding its book value.
Our method of estimating excess and obsolete inventory has remained consistent for all periods presented. If our recognition of excess or obsolete inventory is, or if our estimates of our inventory’s potential utility become, less favorable than currently expected, additional inventory reserves may be required.
As of December 31, 2021 and 2020, the Company made the determination that raw material inventories were such that the likelihood of significant usage within the current year was doubtful and reclassified such raw material inventories as non-current in the reported financial statements.
We determine our normal operating capacity and record as an expense costs attributable to lower utilization of equipment and staff. For the years ended December 31, 2021 and 2020, such expenses were $99,000 and $132,000, respectively.
Investments
We invest our available cash primarily in U.S. Treasury securities, investment grade commercial paper, FDIC guaranteed certificates of deposit, common stock, equity-related securities and corporate notes. Investments classified as available-for-sale debt securities are carried at fair value with unrealized gains and losses recorded in accumulated other comprehensive income (loss). Investments in equity securities are reported at fair value, with both realized and unrealized gains and losses recorded in other income (expense), in the Consolidated Statements of Operations. Investments in which we have the ability and intent, if necessary, to liquidate in order to support our current operations are classified as short-term.
We review our available-for-sale debt securities investments at the end of each quarter for other-than-temporary declines in fair value based on the specific identification method. We consider various factors in determining whether an impairment is other-than-temporary, including the severity and duration of the impairment, changes in underlying credit ratings, forecasted recovery, our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. When we conclude that an other-than-temporary impairment has resulted, the difference between the fair value and carrying value is written off and recorded as a charge on the Consolidated Statement of Operations. As of December 31, 2021, and 2020, no impairment was recorded.
Allowance for doubtful accounts
We estimate the allowance for doubtful accounts based on an assessment of the collectability of specific customer accounts. The determination of risk for collection is assessed on a customer-by-customer basis considering our historical experience and expected future orders with the customer, changes in payment patterns and recent information we have about the current status of our accounts receivable balances. If we determine that a specific customer is a risk for collection, we provide a specific allowance for credit losses to reduce the net recognized receivable to the amount we reasonably believe will be collected. If a receivable is deemed uncollectible, and the account balance differs from the allowance provided, the specific amount is written off to bad debt expense. We believe that based on the customers to whom we sell and the nature of our agreements with them, our estimates are reasonable. Our method of estimating collectability has remained consistent for all periods presented and with past collections experience.
Assets held for sale and long-lived assets
When circumstances, such as adverse market conditions, indicate that the carrying value of a long-lived asset may be impaired, we perform an analysis to review the recoverability of the asset’s carrying value using estimates of the undiscounted cash flows (excluding interest charges) from the expected future operations of the asset. These estimates consider factors such as expected future operating income, operating trends and prospects, as well as the effects of demand, competition and other factors. If the analysis indicates that the carrying value is not recoverable from future cash flows, an impairment loss is recognized to the extent that the carrying value exceeds the estimated fair value. The estimated fair value of assets is determined using appraisal techniques which assume the highest and best use of the asset by market participants, considering the use of the asset that is physically possible, legally permissible, and financially feasible at the measurement date. Any impairment losses are recorded as operating expenses, which reduce net income.
In June 2020, the Company completed the sale of its Malaysian facility for a net sale price of approximately $4,800,000 (based on the exchange rate on June 30, 2020 of $1=MYR4.27) after the payment of consent fees, real estate taxes, brokerage and legal fees, transfer and other expenses. The Company recorded a gain on the disposal of the Malaysian facility of approximately $1,800,000. In December 2020, the Company completed the sale of all of the outstanding shares of capital stock of its wholly owned subsidiary Rubicon Sapphire Technology (Malaysia) SDN BHD. The company recorded a gain on such stock sale of $261,000.
On February 7, 2022, we entered into a real estate sale contract to sell our parcel of land in Batavia, Illinois for $722,000 and expect our net proceeds, if the sale is consummated, after the payment of fees, real estate taxes, brokerage and legal fees, transfer and withholding taxes and other expenses to be approximately $600,000. The closing of the sale of the property is subject to certain conditions precedent. While there is currently no anticipated closing date, we expect to complete the sale within the next twelve-month period. As such, this property was classified as current assets held for sale at December 31, 2021 and 2020.
Stock-based compensation
We grant stock-based compensation in the form of stock options, restricted stock units (“RSUs”) and restricted stock. We expense stock options based upon the fair value on the date of grant. We use the Black-Scholes option pricing model to determine the fair value of stock options. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by assumptions regarding a number of complex and subjective variables. These variables include our expected stock volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rates, forfeitures and expected dividends.
The expected term represents the weighted-average period that our stock options are expected to be outstanding and is based upon five years of historical data. We estimate the volatility of our common stock based on a five-year historical stock price. We base the risk-free interest rate that we use in the option pricing model on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options. We do not anticipate paying any cash dividends in the foreseeable future and, therefore, use an expected dividend yield of zero in the option pricing model. We are required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The current forfeiture rate of 36.13% was based on our past history of forfeitures.
All stock options are granted at an exercise price per share equal to the closing market price of our common stock on the last market trading day prior to the date of grant. Therefore, there is no intrinsic value because the exercise price per share of each option was equal to the fair value of the common stock on the date of grant.
We used a Monte Carlo simulation model valuation technique to determine the fair value of RSUs granted to a key executive pursuant to an employment agreement, because the awards vest based upon achievement of market price targets of our common stock. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award and calculates the fair value of each RSU. The daily expected stock price volatility is based on a four-year historical volatility of our common stock. The daily expected dividend yield is based on annual expected dividend payments. The average daily risk-free interest rate is based on the three-year treasury yield as of the grant date. Each of the tranches is calculated to have its own fair value and requisite service period. The fair value of each tranche is amortized over the requisite or derived service period, which is up to four years.
We allocate stock-based compensation costs relating to options using a straight-line method which amortizes the fair value of each option on a straight-line basis over the service period, but in no event less than the amount vested.
All option grants are granted at an exercise price per share equal to the closing market price of our common stock on the day before the date of grant. Therefore, there is no intrinsic value because the exercise price per share of each option was equal to the fair value of the common stock on the date of grant. Based on the fair value of the common stock on December 31, 2021, there was $7,000 of intrinsic value arising from 4,050 stock options exercisable or outstanding.
For more information on stock-based compensation, see Note 7 - Stock Incentive Plans to our Consolidated Financial Statements included in this Annual Report on Form 10-K.
Income tax valuation allowance
Evaluating the need for and amount of a valuation allowance for deferred tax assets often requires significant judgment and extensive analysis of all the positive and negative evidence available to determine whether all or some portion of the deferred tax assets will not be realized. A valuation allowance must be established for deferred tax assets when it is more likely than not (a probability level of more than 50%) that they will not be realized. In general, “realization” refers to the incremental benefit achieved through the reduction in future taxes payable or an increase in future taxes refundable from the deferred tax assets, assuming that the underlying deductible differences and carryforwards are the last items to enter into the determination of future taxable income. In determining our valuation allowance, we consider the source of taxable income including taxable income in prior carryback years, future reversals of existing temporary differences, the required use of tax planning strategies, and future taxable income exclusive of reversing temporary differences and carryforwards. We are in a cumulative loss position for the past three years which is considered significant negative evidence that is difficult to overcome on a “more likely than not” standard through objectively verifiable data. Under the accounting standards, verifiable evidence will have greater weight than subjective evidence such as our projections for future growth. Based on an evaluation in accordance with the accounting standards, as of December 31, 2021, a valuation allowance has been recorded against the net U.S. deferred tax assets in order to measure only the portion of the deferred tax assets that are more likely than not to be realized based on the weight of all the available evidence. Any U.S. and Malaysia tax benefit or tax expense recorded on the Consolidated Statement of Operations will be offset with a corresponding adjustment from the use of the NOL carryforward asset which currently has a full valuation allowance. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.
Accounting for uncertainty in income taxes
We recognize the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. At December 31, 2021 and 2020, we had $1.1 million of unrecognized tax benefits taken or expected to be taken in a tax return that have been recorded on our financial statements as an offset to the valuation allowance related to tax positions taken in 2012. We recognize interest and/or penalties related to income tax matters in income tax expense. There were no interest or penalties related to income taxes that have been accrued or recognized as of and for the years ended December 31, 2021 and 2020.
The Company is subject to taxation in the U.S. and in a U.S. state jurisdiction. Due to the existence of NOL carryforwards, tax years ended December 31, 2006, 2008, 2009 and 2012 through 2020 are open to examination by tax authorities for Federal purposes. Due to NOL carryforwards at the State level, tax years ended 2012 through 2020 are open to examination by state tax authorities.

ITEM 9A. CONTROLS AND PROCEDURES
Management’s Evaluation of Disclosure Controls and Procedures.
An evaluation was performed under the supervision and with the participation of our management, including our chief executive officer and acting chief financial officer (“certifying officer”), of the effectiveness of the design and operation of our 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”)) as of the end of the year covered by this report. Disclosure controls and procedures are controls and other procedures designed to ensure that information required to be disclosed by us in our periodic reports filed with the SEC is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms, and that the information is accumulated and communicated to our management, including the chief executive officer and acting chief financial officer, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation, our certifying officer concluded that these disclosure controls and procedures were effective as of December 31, 2021.
Management’s Report on Internal Control over Financial Reporting
The financial statements were prepared by management, which is responsible for their integrity and objectivity and for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f).
The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s 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 disposition of the assets of the Company;
ii. provide reasonable assurance that transactions are recorded as necessary to permit preparation of Consolidated Financial Statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and
iii. provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Consolidated Financial Statements.
There are inherent limitations in the effectiveness of any internal control, including the possibility of human error and the circumvention or overriding of controls. Accordingly, even effective internal controls can provide only reasonable assurance with respect to the financial statement preparation. Further, because of changes in conditions, the effectiveness of internal controls may vary over time.
Management assessed the design and effectiveness of the Company’s internal control over financial reporting as of December 31,2021. In making this assessment, management used the criteria set forth in 2013 Internal Control-Integrated Framework by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
Based on management’s assessment using those criteria, as of December 31, 2021, management concluded that the Company’s internal control over financial reporting was effective.
This annual report does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. The Company’s internal controls over financial reporting were not subject to attestation by our independent registered public accounting firm pursuant to rules of the SEC.
Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2021, that our certifying officers concluded materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
