However, current conditions in the auction rate securities market have led management to conclude the recovery period for the Failed Auction Security <ix:nonNumeric name="vicr:PeriodForWhichFailedAuctionSecuritiesBeenInUnrealizedLossPosition" contextRef="P01_01_2021To03_31_2021_AuctionRateSecuritiesMemberusgaapFinancialInstrumentAxis">exceeds 12 months</ix:nonNumeric>.

As such, the Company&#8217;s investment in the Failed Auction Security was deemed to require valuation using Level&#160;3 inputs. Management, after consulting with advisors, valued the Failed Auction Security using analyses and pricing models similar to those used by market participants (i.e., buyers, sellers, and the broker-dealers responsible for execution of the Dutch auction pricing mechanism by which each issue&#8217;s interest rate was set). Management utilized a probability weighted discounted cash flow (&#8220;DCF&#8221;) model to determine the estimated fair value of this security as of March&#160;31, 2021. The major assumptions used in preparing the DCF model were similar to those described in Note 5 - Fair Value Measurements in the Notes to the Consolidated Financial Statements contained in the Company&#8217;s 2020 Form <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">10-K.</div> </div> <ix:nonNumeric name="us-gaap:FairValueAssetsAndLiabilitiesMeasuredOnRecurringAndNonrecurringBasisValuationTechniquesTableTextBlock" contextRef="P01_01_2021To03_31_2021" escape="true"><div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Quantitative information about Level&#160;3 fair value measurements as of March&#160;31, 2021 is as follows (dollars in thousands): </div></div> <div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

Management assesses the need for the valuation allowance on a quarterly basis. In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and past financial performance. While recent positive operating results, as a result of increases in bookings, caused the Company to be in a cumulative income position as of March&#160;31, 2021, the Company faces uncertainties in forecasting its operating results due to the continued impact of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic on the Company&#8217;s supply chain, certain process issues with the production of Advanced Products and the unpredictability in certain markets. This operating uncertainty also makes it difficult to predict the availability and utilization of tax benefits over the next several years. As a result, management has concluded, at this time, it is more likely than not the Company&#8217;s net domestic deferred tax assets will not be realized, and a full valuation allowance against all net domestic deferred tax assets was still warranted as of March&#160;31, 2021. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. If the positive quarterly earnings and increases in bookings continue, and the Company&#8217;s concerns about industry uncertainty and world events, including the impact of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic on the Company&#8217;s supply chain, and process issues with the production of Advanced Products are resolved, and the amount of tax benefits the Company is able to utilize to the point that the Company believes future taxable income can be more reliably forecasted, the Company may release all or a portion of the valuation allowance in the near-term. Certain state tax credits, though, will likely never be released by the valuation allowance. If and when the Company determines the valuation allowance should be released (i.e., reduced), the adjustment would result in a tax benefit reported in that period&#8217;s Consolidated Statements of Operations, the effect of which would be an increase in reported net income. </div></ix:nonNumeric> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">-15- </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="font-size: 13.28px; margin-top: 1.67em; margin-bottom: 1.67em;; margin-block-start: 1.67em; margin-block-end: 1.67em;;font-weight: bold;"><a href="#toc">Table of Contents</a></div> <div style="text-align: center;"><div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">VICOR CORPORATION </div></div><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Notes to Condensed Consolidated Financial Statements </div></div><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">March 31, 2021 </div></div><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">(unaudited) </div></div><div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div><ix:nonNumeric name="us-gaap:EarningsPerShareTextBlock" contextRef="P01_01_2021To03_31_2021" escape="true"><div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">9. <div style="text-decoration: underline; letter-spacing: 0px; top: 0px;;display:inline;">Net Income (Loss) per Share</div> </div><ix:nonNumeric name="us-gaap:ScheduleOfEarningsPerShareBasicAndDilutedTableTextBlock" contextRef="P01_01_2021To03_31_2021" escape="true"><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands, except per share amounts): </div></div><div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

(&#8220;SynQor&#8221;) in the U.S. District Court for the Eastern District of Texas (the &#8220;Texas Action&#8221;). The complaint, as amended, alleges that the Company&#8217;s products, including but not limited to, unregulated bus converters used in intermediate bus architecture power supply systems, infringe SynQor&#8217;s U.S. patent numbers 7,072,190, 7,272,021, 7,564,702, and 8,023,290 (&#8220;the &#8216;190 patent&#8221;, &#8220;the &#8216;021 patent&#8221;, &#8220;the &#8216;702 patent&#8221;, and &#8220;the &#8216;290 patent&#8221;, respectively). SynQor&#8217;s complaint sought an injunction against further infringement and an award of unspecified compensatory and enhanced damages, interest, costs and attorney fees. The Company has denied that its products infringe any of the SynQor patents, and has asserted that the SynQor patents are invalid and/or unenforceable. The Company has also asserted counterclaims seeking damages from SynQor for deceptive trade practices and tortious interference with prospective economic advantage arising from SynQor&#8217;s attempted enforcement of its patents against the Company. </div></div></ix:nonNumeric><div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">-16- </div></div></div></div><div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div><hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/><div style="font-size: 13.28px; margin-top: 1.67em; margin-bottom: 1.67em;; margin-block-start: 1.67em; margin-block-end: 1.67em;;font-weight: bold;"><a href="#toc">Table of Contents</a></div><div style="text-align: center;"><div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">VICOR CORPORATION </div></div><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Notes to Condensed Consolidated Financial Statements </div></div><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">March 31, 2021 </div></div><div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">(unaudited) </div></div><div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div><ix:continuation id="TextSelection_21135000" continuedAt="TextSelectionAppend_21135000_1"><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On May&#160;23, 2016, after extensive discovery, the Texas Action was stayed by the court pending completion of certain inter partes reexamination (&#8220;IPRx&#8221;) proceedings at the United States Patent and Trademark Office (&#8220;USPTO&#8221;) (including any appeals from such proceedings to the Federal Circuit (as defined below)) concerning the SynQor patents, which are described below. That stay remains in force. On March&#160;17, 2021, SynQor filed a motion to lift the stay in the Texas Action. The Company has opposed that motion, which remains pending. </div></div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In 2011, in response to the filing of the Texas Action, the Company initiated IPRx proceedings at the USPTO challenging the validity of all claims that were asserted against the Company by SynQor. The current status of these proceedings is as follows. Regarding the &#8216;190 patent IPRx, the United States Court of Appeals for the Federal Circuit (the &#8220;Federal Circuit&#8221;) issued a decision on March&#160;13, 2015, determining that certain claims were invalid and remanding the matter to the Patent Trial and Appeal Board (&#8220;PTAB&#8221;) of the USPTO for further proceedings. On February&#160;20, 2019, the PTAB issued a decision finding that all of the remaining challenged claims were unpatentable. SynQor appealed that decision. On February&#160;22, 2021, the Federal Circuit issued a decision in that appeal. In a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">2-1</div> ruling, the Federal Circuit vacated and remanded the PTAB&#8217;s decision, finding that the reasoning the PTAB had relied on in reaching its decision was precluded by certain prior PTAB rulings regarding the &#8216;290 and &#8216;702 patents. On April&#160;7, 2021, the Company filed a petition for panel rehearing and rehearing <div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">en banc</div></div> of the Federal Circuit&#8217;s February&#160;22, 2021 decision. </div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On August&#160;30, 2017, the Federal Circuit issued rulings with regard to the IPRx proceedings for the &#8217;021, &#8216;702 and &#8216;290 patents. With respect to the &#8216;021 patent, the Federal Circuit affirmed the PTAB&#8217;s determination that all of the challenged claims of the &#8216;021 patent were invalid. The Federal Circuit remanded the case to the PTAB for further consideration of the patentability of certain claims that had been added by amendment during the reexamination. On February&#160;20, 2019, the PTAB issued a decision affirming the examiner&#8217;s rejections of all challenged claims. SynQor has filed an appeal of that decision in the Federal Circuit. That appeal has been stayed pending resolution of the pending appeal regarding the &#8216;190 patent IPRx. With respect to the &#8216;702 patent, the Federal Circuit affirmed the PTAB&#8217;s determination that all of the challenged claims of the &#8216;702 patent were patentable. With respect to the &#8216;290 patent, the Federal Circuit vacated the PTAB&#8217;s decision upholding the patentability of the &#8216;290 patent claims, and remanded the case to the PTAB for further consideration. On February&#160;20, 2019, the PTAB issued a decision reversing its prior affirmance of the examiner&#8217;s <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-adoption</div> of rejections with respect to the &#8216;290 patent, and entering rejections of all of the claims of the &#8216;290 patent. On May&#160;20, 2019, as permitted by USPTO rules, SynQor requested the USPTO to reopen prosecution of this proceeding to address the new rejections made by the PTAB. On September&#160;28, 2020, the examiner issued a decision reaffirming the PTAB&#8217;s rejection of all of the claims of the &#8216;290 patent. On March&#160;18, 2021, SynQor appealed this decision to the PTAB, which appeal remains pending. </div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On October&#160;31, 2017, the Company filed a request with the USPTO for ex parte reexamination (&#8220;EPRx&#8221;) of the asserted claims of the &#8216;702 patent, based on different prior art references than had been at issue in the previous IPRx of the &#8216;702 patent. On August&#160;6, 2018, the Company filed a similar request with the USPTO for EPRx of the asserted claims of the &#8216;190 patent, based on different prior art references than had been at issue in the previous IPRx of the &#8216;190 patent. On December&#160;18, 2020, the PTAB issued rulings upholding the validity of the asserted claims in the EPRx proceedings for both the &#8216;702 and &#8216;190 patents. Accordingly, both of those proceedings are now terminated. </div></div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On January&#160;23, 2018, the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">20-year</div> terms of the &#8216;190 patent, the &#8216;021 patent, the &#8216;702 patent and the &#8216;290 patent expired. As a consequence of these expirations, the Company cannot be liable under any of the SynQor patents for allegedly infringing activities occurring after that date. In addition, any amended claims that may issue as a result of any of the still-pending reexamination proceedings will have no effective term and cannot be the basis for any liability by the Company. </div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company continues to believe none of its products, including its unregulated bus converters, infringe any valid claim of the asserted SynQor patents, either alone or when used in an intermediate bus architecture implementation. The Company believes SynQor&#8217;s claims lack merit and, therefore, it continues to vigorously defend itself against SynQor&#8217;s patent infringement allegations.

Our competitive position is supported by innovations in product design and achievements in product performance, largely enabled by our focus on the research and development of advanced technologies and processes, often implemented in proprietary semiconductor circuitry, materials, and packaging. Many of our products incorporate patented or proprietary implementations of high-frequency switching topologies enabling power system solutions that are more efficient and much smaller than conventional alternatives. Our strategy emphasizes demonstrable product differentiation and a value proposition based on competitively superior solution performance, advantageous design flexibility, and a compelling total cost of ownership. While we offer a wide range of alternating current (&#8220;AC&#8221;) and direct current (&#8220;DC&#8221;) power conversion products, we consider our core competencies to be associated with 48V DC distribution, which offers numerous inherent cost and performance advantages over lower distribution voltages. However, we also offer products addressing other DC voltage standards (e.g., 380V for power distribution in data centers, 110V for rail applications, 28V for military and avionics applications, and 24V for industrial automation). </div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Based on design, performance, and form factor considerations, as well as the range of evolving applications for which our products are appropriate, we categorize our product portfolios as either &#8220;Advanced Products&#8221; or &#8220;Brick Products.&#8221; The Advanced Products category consists of our more recently introduced products, which are largely used to implement our proprietary Factorized Power Architecture<div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px">&#8482;</div> (&#8220;FPA&#8221;), an innovative power distribution architecture enabling flexible, rapid power system design using individual components optimized to perform a specific conversion function. </div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The Brick Products category largely consists of our broad and well-established families of integrated power converters, incorporating multiple conversion stages, used in conventional power systems architectures. Given the growth profiles of the markets we serve with our Advanced Products line and our Brick Products line, our strategy involves a transition in organizational focus, emphasizing investment in our Advanced Products line and targeting high growth market segments with a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">low-mix,</div> high-volume operational model, while maintaining a profitable business in the mature market segments we serve with our Brick Products line with a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">high-mix,</div> <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">low-volume</div> operational model. </div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The applications in which our Advanced Products and Brick Products are used are typically in the higher-performance, higher-power segments of the market segments we serve. With our Advanced Products, we generally serve large Original Equipment Manufacturers (&#8220;OEMs&#8221;), Original Design Manufacturers (&#8220;ODMs&#8221;), and their contract manufacturers, with sales currently concentrated in the data center and hyperscaler segments of enterprise computing, in which our products are used for voltage distribution on server motherboards, in server racks, and across datacenter infrastructure. We have established a leadership position in the emerging market segment for powering high-performance processors used for acceleration of applications associated with artificial intelligence (&#8220;AI&#8221;). Our customers in the AI market segment include the leading innovators in processor and accelerator design, as well as early adopters in cloud computing and high performance computing. We also target applications in aerospace and aviation, defense electronics, industrial automation, instrumentation, test equipment, solid state lighting, telecommunications and networking infrastructure, and vehicles (notably in the autonomous driving, electric vehicle, and hybrid vehicle niches of the vehicle segment). With our Brick Products, we generally serve a fragmented base of large and small customers, concentrated in aerospace and defense electronics, industrial automation, industrial equipment, instrumentation and test equipment, and transportation (notably in rail and heavy equipment applications). With our strategic emphasis on larger, high-volume customers, we expect to experience over time a greater concentration of sales among relatively fewer customers. </div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Our quarterly consolidated operating results can be difficult to forecast and have been subject to significant fluctuations. We plan our production and inventory levels based on management&#8217;s estimates of customer demand, customer forecasts, and other information sources. Customer forecasts, particularly those of OEM, ODM, and contract manufacturing customers to which we supply Advanced Products in high volumes, are subject to scheduling changes on short notice, contributing to operating inefficiencies and excess costs. In addition, external factors such as supply chain uncertainties, which are often associated with the cyclicality of the electronics industry, regional macroeconomic and trade-related circumstances, and <div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">force majeure</div></div> events (most recently evidenced by the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic), have caused our operating results to vary meaningfully. Our quarterly gross margin as a percentage of net revenues may vary, depending on production volumes, average selling prices, average unit costs, the mix of products sold during that quarter, and the level of importation of raw materials subject to tariffs. Our quarterly operating margin as a percentage of net revenues also may vary with changes in revenue and product level profitability, but our operating costs are largely associated with compensation and related employee costs, which are not subject to sudden or significant changes. </div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">-20- </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="font-size: 13.28px; margin-top: 1.67em; margin-bottom: 1.67em;; margin-block-start: 1.67em; margin-block-end: 1.67em;;font-weight: bold;"><a href="#toc">Table of Contents</a></div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">VICOR CORPORATION </div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Management&#8217;s Discussion and Analysis of </div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Financial Condition and Results of Operation </div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">March 31, 2021 </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;">Impact of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> Pandemic </div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">On January&#160;30, 2020, the World Health Organization designated the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> outbreak a &#8220;Public Health Emergency of International Concern&#8221; (i.e., a health emergency requiring coordinated action by the governments of effected countries).

Governments worldwide have responded with measures intended to contain the further spread of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19,</div> including mandatory closures of businesses, schools, and organizations. </div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On March&#160;23, 2020, the Commonwealth of Massachusetts ordered <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-essential</div> businesses closed and prohibited gatherings of more than 10 people, extending the Commonwealth&#8217;s emergency declaration made on March&#160;10, 2020. Our headquarters and primary manufacturing facility are located in Massachusetts. However, the Company is designated as essential by the U.S. Department of Homeland Security, given our role in supporting industrial sectors considered &#8220;critical infrastructure.&#8221; As such, we have continued to operate at, or close to, full manufacturing capacity, although there can be no assurance we will be able to continue to operate at such levels of manufacturing capacity. </div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Widespread uncertainty associated with the pandemic has contributed to reduced business activity worldwide.&#160;We experienced production constraints throughout 2020 that resulted in delays, inefficiencies, and higher costs, which, in the aggregate, had a detrimental influence on our financial results for the four quarters of 2020. While still present to a certain extent, these constraints had a reduced impact on our financial results for the first quarter of 2021. Given ongoing uncertainty, there is no assurance that our financial performance will not continue to be negatively influenced as a result of the pandemic. </div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Since early March 2020, we have taken actions intended to protect the health and safety of our employees, customers, business partners, and suppliers. Following guidance from the U.S. Centers for Disease Control and Prevention, the U.S. Occupational Health and Safety Administration, state and local health authorities, and existing internal crisis management policies, we developed and implemented comprehensive health and safety measures at all of our locations, including: establishing a central response team; distributing information and carrying out education initiatives; implementing social distancing requirements, including the installation of transparent panels to physically separate individuals when in close proximity; distributing breathing masks, disposable gloves, disinfectant wipes, and thermometers to employees; implementing temperature checks at the entrances to our manufacturing facility; extensive and frequent disinfecting of our workspaces; modifying our meal services to minimize physical contact; enabling work-from-home arrangements for those employees who do not need to be physically on premises to perform their work effectively; and suspending travel. We expect to maintain these measures until we determine the pandemic is adequately contained for purposes of our business, and we may take further actions we consider to be in the best interests of our employees, customers, business partners, and suppliers, or in response to further government mandates or requirements. </div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">As of the date of this report, while we have seen a small increase in cases again recently, cases are below the levels experienced in the December through January time frame, and absenteeism has declined since the December through January time frame. The productivity of our factory may be reduced if quarantine rates increase or if the number of employees diagnosed with <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> requires further implementation of restrictive health and safety measures, including factory closure. We continue to operate with three shifts in our factory, and, with few exceptions, our engineering, sales, and administrative personnel are working from the Company&#8217;s offices. </div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We are closely monitoring the operating performance and financial health of our customers, business partners, and suppliers, but an extended period of operational constraints brought about by the pandemic could cause financial hardship within our customer base and supply chain. Such hardship may continue to disrupt customer demand and limit our customers&#8217; ability to meet their obligations to us. Similarly, such hardship within our supply chain could continue to restrict our access to raw materials or services. Additionally, restrictions or disruptions of transportation, such as reduced availability of cargo transport by ship or air, could result in higher costs and inbound and outbound delays. During 2020, we took steps to address certain supply chain risks, and we believe our actions mitigated those risks, particularly for the second half of the year; however, there are no assurances that those steps will continue to mitigate risks in 2021 and beyond. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">-21- </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="font-size: 13.28px; margin-top: 1.67em; margin-bottom: 1.67em;; margin-block-start: 1.67em; margin-block-end: 1.67em;;font-weight: bold;"><a href="#toc">Table of Contents</a></div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">VICOR CORPORATION </div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Management&#8217;s Discussion and Analysis of </div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Financial Condition and Results of Operation </div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">March 31, 2021 </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Although there is uncertainty regarding the extent to which the pandemic will continue to impact our operational and financial results in the future, the Company&#8217;s high level of liquidity (supplemented by the approximately $109.7&#160;million of net proceeds from the public offering of shares of our Common Stock during the second quarter of 2020), flexible operational model, existing raw material inventories, and increased use of second sources for critical manufacturing inputs together support management&#8217;s belief the Company will be able to effectively conduct business until the pandemic passes. </div></div> <div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">We are monitoring the rapidly changing circumstances, and may take additional actions to address <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> risks as they evolve.

Advanced Products revenue rose 2.2% sequentially compared to the fourth quarter of 2020. This growth, though, was constrained by limited component availability due to global semiconductor supply allocation issues experienced during the quarter. Brick Products revenue rose 7.6% sequentially compared to the fourth quarter of 2020, reflecting a resumption of shipments to our European customers, after the pandemic-related trough of 2020, while shipments to Asian customers grew 18.5%. </div></div> </td> </tr> </table> <div style="clear: both; max-height: 0px; background: none;"></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

The primary uses of cash during the three months ended March&#160;31, 2021 were $50,706,000 for the purchases of short-term investments and $9,264,000 for the purchase of property and equipment. </div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In November 2000, our Board of Directors authorized the repurchase of up to $30,000,000 of our Common Stock (the &#8220;November 2000 Plan&#8221;). The November 2000 Plan authorizes us to make such repurchases from time to time in the open market or through privately negotiated transactions. The timing and amounts of Common Stock repurchases are at the discretion of management based on its view of economic and financial market conditions. We did not repurchase shares of Common Stock under the November 2000 Plan during the three months ended March&#160;31, 2021. As of March&#160;31, 2021, we had approximately $8,541,000 remaining available for repurchases of our Common Stock under the November 2000 Plan. </div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As of March&#160;31, 2021, we had approximately $11,457,000 of capital expenditure commitments, principally for manufacturing equipment, which we intend to fund with existing cash. In addition to these commitments, we had, in aggregate, approximately $38,000,000 of remaining budgeted capital expenditures in 2021 associated with the construction of a 90,000 sq. ft. addition to the Company&#8217;s existing manufacturing facility and the installation of new production equipment. Our primary needs for liquidity are for making continuing investments in manufacturing equipment and for funding the construction of the additional manufacturing space adjoining our existing Andover manufacturing facility, noted above, including architectural and construction costs. We believe cash generated from operations together with our available cash and cash equivalents and short-term investments will be sufficient to fund planned operational needs, capital equipment purchases, and the planned construction, for the foreseeable future. </div></div> </div> </div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">-27- </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="font-size: 13.28px; margin-top: 1.67em; margin-bottom: 1.67em;; margin-block-start: 1.67em; margin-block-end: 1.67em;;font-weight: bold;"><a href="#toc">Table of Contents</a></div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Vicor Corporation </div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">March 31, 2021 </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div id="toc154240_10" style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="text-decoration: underline; letter-spacing: 0px; top: 0px;;display:inline;">Item 3 &#8212; Quantitative and Qualitative Disclosures About Market Risk </div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">We are exposed to a variety of market risks, including changes in interest rates affecting the return on our cash and cash equivalents, our short-term investments and fluctuations in foreign currency exchange rates. As our cash and cash equivalents and short-term investments consist principally of cash accounts, money market securities, and U.S. Treasury securities, which are short-term in nature, we believe our exposure to market risk on interest rate fluctuations for these investments is not significant. As of March&#160;31, 2021, our long-term investment portfolio, recorded on our Condensed Consolidated Balance Sheet as &#8220;Long-term investments, net&#8221;, consisted of a single auction rate security with a par value of $3,000,000, purchased through and held in custody by a broker-dealer affiliate of Bank of America, N.A., that has experienced failed auctions (the &#8220;Failed Auction Security&#8221;) since February 2008. While the Failed Auction Security is Aaa/AA+ rated by major credit rating agencies, collateralized by student loans and guaranteed by the U.S. Department of Education under the Federal Family Education Loan Program, continued failure to sell at its periodic auction dates (i.e., reset dates) could negatively impact the carrying value of the investment, in turn leading to impairment charges in future periods. Periodic changes in the fair value of the Failed Auction Security attributable to credit loss (i.e., risk of the issuer&#8217;s default) are recorded through earnings as a component of &#8220;Other income (expense), net&#8221;, with the remainder of any periodic change in fair value not related to credit loss (i.e., temporary <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">&#8220;mark-to-market&#8221;</div></div> carrying value adjustments) recorded in &#8220;Accumulated other comprehensive (loss) income&#8221;, a component of Stockholders&#8217; Equity. Should we conclude a decline in the fair value of the Failed Auction Security is other than temporary, such losses would be recorded through earnings as a component of &#8220;Other income (expense), net&#8221;. We do not believe there was an &#8220;other-than-temporary&#8221; decline in value in this security as of March&#160;31, 2021. </div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Our exposure to market risk for fluctuations in foreign currency exchange rates relates to the operations of VJCL, for which the functional currency is the Japanese Yen, and changes in the relative value of the Yen to the U.S.&#160;Dollar. The functional currency of all other subsidiaries in Europe and other subsidiaries in Asia is the U.S.&#160;Dollar. While we believe the risk of fluctuations in foreign currency exchange rates for these subsidiaries is generally not significant, they can be subject to substantial currency changes, and therefore foreign exchange exposures. </div></div> <div id="toc154240_11" style="font-family: Times New Roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="text-decoration: underline; letter-spacing: 0px; top: 0px;;display:inline;">Item 4 &#8212; Controls and Procedures </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

The term &#8220;disclosure controls and procedures,&#8221; as defined in <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">Rules&#160;13a-15(e)</div> and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">15d-15(e)</div> under the Exchange Act, means controls and other procedures of a company that are designed to ensure 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 Securities and Exchange Commission&#8217;s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure information required to be disclosed by a company in the reports it files or submits under the Exchange Act is accumulated and communicated to the company&#8217;s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes 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. Based on the evaluation of our disclosure controls and procedures as of March&#160;31, 2021, our CEO and IPFO concluded, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level. </div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system&#8217;s objectives will be met. Accordingly, management, including the CEO and IPFO, recognizes our disclosure controls or our internal control over financial reporting may not prevent or detect all errors and all fraud. The design of a control system must reflect the fact there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls.

If the Company&#x2019;s estimated demand and/or market expectation were to change or if product sales were to decline, the Company&#x2019;s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues. &lt;/div&gt;&lt;/div&gt; &lt;div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Inventories were as follows (in thousands): &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

The Failed Auction Security held by the Company is Aaa/AA+ rated by major credit rating agencies, is collateralized by student loans, and is guaranteed by the U.S. Department of Education under the Federal Family Education Loan Program. Management is not aware of any reason to believe the issuer of the Failed Auction&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Security is presently at risk of default. Through March&#160;31, 2021, the Company has continued to receive interest payments on the Failed Auction Security in accordance with the terms of its indenture. Management believes the Company ultimately should be able to liquidate the Failed Auction Security without significant loss primarily due to the overall quality of the issue held and the collateral securing the substantial majority of the underlying obligation. However, current conditions in the auction rate securities market have led management to conclude the recovery period for the Failed Auction Security exceeds 12 months. As a result, the Company continued to classify the Failed Auction Security as long-term as of March&#160;31, 2021. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Details of our investments are as follows (in thousands): &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

The gross unrealized loss of $459,000 on the Failed Auction Security consists of two types of estimated loss: an aggregate credit loss of $32,000 and an aggregate temporary impairment of $427,000. In determining the amount of credit loss, the Company compared the present value of cash flows expected to be collected to the amortized cost basis of the security, considering credit default risk probabilities and changes in credit ratings as significant inputs, among other factors. &lt;/div&gt;&lt;/div&gt; &lt;div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The following table represents a rollforward of the activity related to the credit loss recognized in earnings on the Failed Auction Security for the three months ended March&#160;31 (in thousands): &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

As such, the Company&#x2019;s investment in the Failed Auction Security was deemed to require valuation using Level&#160;3 inputs. Management, after consulting with advisors, valued the Failed Auction Security using analyses and pricing models similar to those used by market participants (i.e., buyers, sellers, and the broker-dealers responsible for execution of the Dutch auction pricing mechanism by which each issue&#x2019;s interest rate was set). Management utilized a probability weighted discounted cash flow (&#x201c;DCF&#x201d;) model to determine the estimated fair value of this security as of March&#160;31, 2021. The major assumptions used in preparing the DCF model were similar to those described in Note 5 - Fair Value Measurements in the Notes to the Consolidated Financial Statements contained in the Company&#x2019;s 2020 Form &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;10-K.&lt;/div&gt; &lt;/div&gt; &lt;div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Quantitative information about Level&#160;3 fair value measurements as of March&#160;31, 2021 is as follows (dollars in thousands): &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

The benefit for income taxes for the three months ended March&#160;31, 2021 and 2020 included estimated foreign income taxes and estimated state taxes in jurisdictions in which the Company does not have sufficient net operating loss carryforwards. &lt;/div&gt;&lt;/div&gt; &lt;div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;As of March&#160;31, 2021, the Company had a valuation allowance of approximately $37,856,000 against all net domestic deferred tax assets, for which realization cannot be considered more likely than not at this time. Management assesses the need for the valuation allowance on a quarterly basis. In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and past financial performance. While recent positive operating results, as a result of increases in bookings, caused the Company to be in a cumulative income position as of March&#160;31, 2021, the Company faces uncertainties in forecasting its operating results due to the continued impact of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;COVID-19&lt;/div&gt; pandemic on the Company&#x2019;s supply chain, certain process issues with the production of Advanced Products and the unpredictability in certain markets. This operating uncertainty also makes it difficult to predict the availability and utilization of tax benefits over the next several years. As a result, management has concluded, at this time, it is more likely than not the Company&#x2019;s net domestic deferred tax assets will not be realized, and a full valuation allowance against all net domestic deferred tax assets was still warranted as of March&#160;31, 2021. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. If the positive quarterly earnings and increases in bookings continue, and the Company&#x2019;s concerns about industry uncertainty and world events, including the impact of the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;COVID-19&lt;/div&gt; pandemic on the Company&#x2019;s supply chain, and process issues with the production of Advanced Products are resolved, and the amount of tax benefits the Company is able to utilize to the point that the Company believes future taxable income can be more reliably forecasted, the Company may release all or a portion of the valuation allowance in the near-term. Certain state tax credits, though, will likely never be released by the valuation allowance. If and when the Company determines the valuation allowance should be released (i.e., reduced), the adjustment would result in a tax benefit reported in that period&#x2019;s Consolidated Statements of Operations, the effect of which would be an increase in reported net income. &lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

(&#x201c;SynQor&#x201d;) in the U.S. District Court for the Eastern District of Texas (the &#x201c;Texas Action&#x201d;). The complaint, as amended, alleges that the Company&#x2019;s products, including but not limited to, unregulated bus converters used in intermediate bus architecture power supply systems, infringe SynQor&#x2019;s U.S. patent numbers 7,072,190, 7,272,021, 7,564,702, and 8,023,290 (&#x201c;the &#x2018;190 patent&#x201d;, &#x201c;the &#x2018;021 patent&#x201d;, &#x201c;the &#x2018;702 patent&#x201d;, and &#x201c;the &#x2018;290 patent&#x201d;, respectively). SynQor&#x2019;s complaint sought an injunction against further infringement and an award of unspecified compensatory and enhanced damages, interest, costs and attorney fees. The Company has denied that its products infringe any of the SynQor patents, and has asserted that the SynQor patents are invalid and/or unenforceable. The Company has also asserted counterclaims seeking damages from SynQor for deceptive trade practices and tortious interference with prospective economic advantage arising from SynQor&#x2019;s attempted enforcement of its patents against the Company. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On May&#160;23, 2016, after extensive discovery, the Texas Action was stayed by the court pending completion of certain inter partes reexamination (&#x201c;IPRx&#x201d;) proceedings at the United States Patent and Trademark Office (&#x201c;USPTO&#x201d;) (including any appeals from such proceedings to the Federal Circuit (as defined below)) concerning the SynQor patents, which are described below. That stay remains in force. On March&#160;17, 2021, SynQor filed a motion to lift the stay in the Texas Action. The Company has opposed that motion, which remains pending. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;In 2011, in response to the filing of the Texas Action, the Company initiated IPRx proceedings at the USPTO challenging the validity of all claims that were asserted against the Company by SynQor. The current status of these proceedings is as follows. Regarding the &#x2018;190 patent IPRx, the United States Court of Appeals for the Federal Circuit (the &#x201c;Federal Circuit&#x201d;) issued a decision on March&#160;13, 2015, determining that certain claims were invalid and remanding the matter to the Patent Trial and Appeal Board (&#x201c;PTAB&#x201d;) of the USPTO for further proceedings. On February&#160;20, 2019, the PTAB issued a decision finding that all of the remaining challenged claims were unpatentable. SynQor appealed that decision. On February&#160;22, 2021, the Federal Circuit issued a decision in that appeal. In a &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2-1&lt;/div&gt; ruling, the Federal Circuit vacated and remanded the PTAB&#x2019;s decision, finding that the reasoning the PTAB had relied on in reaching its decision was precluded by certain prior PTAB rulings regarding the &#x2018;290 and &#x2018;702 patents. On April&#160;7, 2021, the Company filed a petition for panel rehearing and rehearing &lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;en banc&lt;/div&gt;&lt;/div&gt; of the Federal Circuit&#x2019;s February&#160;22, 2021 decision. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;On August&#160;30, 2017, the Federal Circuit issued rulings with regard to the IPRx proceedings for the &#x2019;021, &#x2018;702 and &#x2018;290 patents. With respect to the &#x2018;021 patent, the Federal Circuit affirmed the PTAB&#x2019;s determination that all of the challenged claims of the &#x2018;021 patent were invalid. The Federal Circuit remanded the case to the PTAB for further consideration of the patentability of certain claims that had been added by amendment during the reexamination. On February&#160;20, 2019, the PTAB issued a decision affirming the examiner&#x2019;s rejections of all challenged claims. SynQor has filed an appeal of that decision in the Federal Circuit. That appeal has been stayed pending resolution of the pending appeal regarding the &#x2018;190 patent IPRx. With respect to the &#x2018;702 patent, the Federal Circuit affirmed the PTAB&#x2019;s determination that all of the challenged claims of the &#x2018;702 patent were patentable. With respect to the &#x2018;290 patent, the Federal Circuit vacated the PTAB&#x2019;s decision upholding the patentability of the &#x2018;290 patent claims, and remanded the case to the PTAB for further consideration. On February&#160;20, 2019, the PTAB issued a decision reversing its prior affirmance of the examiner&#x2019;s &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-adoption&lt;/div&gt; of rejections with respect to the &#x2018;290 patent, and entering rejections of all of the claims of the &#x2018;290 patent. On May&#160;20, 2019, as permitted by USPTO rules, SynQor requested the USPTO to reopen prosecution of this proceeding to address the new rejections made by the PTAB. On September&#160;28, 2020, the examiner issued a decision reaffirming the PTAB&#x2019;s rejection of all of the claims of the &#x2018;290 patent. On March&#160;18, 2021, SynQor appealed this decision to the PTAB, which appeal remains pending. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On October&#160;31, 2017, the Company filed a request with the USPTO for ex parte reexamination (&#x201c;EPRx&#x201d;) of the asserted claims of the &#x2018;702 patent, based on different prior art references than had been at issue in the previous IPRx of the &#x2018;702 patent. On August&#160;6, 2018, the Company filed a similar request with the USPTO for EPRx of the asserted claims of the &#x2018;190 patent, based on different prior art references than had been at issue in the previous IPRx of the &#x2018;190 patent. On December&#160;18, 2020, the PTAB issued rulings upholding the validity of the asserted claims in the EPRx proceedings for both the &#x2018;702 and &#x2018;190 patents. Accordingly, both of those proceedings are now terminated. &lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;On January&#160;23, 2018, the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;20-year&lt;/div&gt; terms of the &#x2018;190 patent, the &#x2018;021 patent, the &#x2018;702 patent and the &#x2018;290 patent expired. As a consequence of these expirations, the Company cannot be liable under any of the SynQor patents for allegedly infringing activities occurring after that date. In addition, any amended claims that may issue as a result of any of the still-pending reexamination proceedings will have no effective term and cannot be the basis for any liability by the Company. &lt;/div&gt;&lt;div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company continues to believe none of its products, including its unregulated bus converters, infringe any valid claim of the asserted SynQor patents, either alone or when used in an intermediate bus architecture implementation. The Company believes SynQor&#x2019;s claims lack merit and, therefore, it continues to vigorously defend itself against SynQor&#x2019;s patent infringement allegations. The Company does not believe a loss is probable for this matter. If a loss were to be incurred, however, the Company cannot estimate the amount of possible loss or range of possible loss at this time. &lt;/div&gt;&lt;/div&gt;&lt;div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;&lt;div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In addition to the SynQor matter, the Company is involved in certain other litigation and claims incidental to the conduct of its business. While the outcome of lawsuits and claims against the Company cannot be predicted with certainty, management does not expect any current litigation or claims will have a material adverse impact on the Company&#x2019;s financial position or results of operations. &lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

This new guidance was effective for the Company for its fiscal year beginning after December&#160;15, 2020, with early adoption permitted. The Company adopted the new guidance as of January&#160;1, 2021. The adoption did not have a material impact on the Company&#x2019;s consolidated financial statements and disclosures. &lt;/div&gt;&lt;/div&gt; &lt;div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Other new pronouncements issued but not effective until after March&#160;31, 2021 are not expected to have a material impact on the Company&#x2019;s consolidated financial statements. &lt;/div&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsAndChangesInAccountingPrinciplesTextBlock>

All shipping, handling and customs (e.g., tariff) costs incurred in connection with the sale of products are included in cost of revenues. </div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Inventory that is estimated to be excess, obsolete or unmarketable is written down to net realizable value. The Company&#8217;s estimation process for assessing net realizable value is based upon management&#8217;s estimate of expected future utility which is derived based on backlog, historical consumption and expected market conditions. If the Company&#8217;s estimated demand and/or market expectation were to change or if product sales were to decline, the Company&#8217;s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues. </div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Inventories were as follows (in thousands): </div></div> <div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

The Failed Auction Security held by the Company is Aaa/AA+ rated by major credit rating agencies, is collateralized by student loans, and is guaranteed by the U.S. Department of Education under the Federal Family Education Loan Program.

Through March&#160;31, 2021, the Company has continued to receive interest payments on the Failed Auction Security in accordance with the terms of its indenture. Management believes the Company ultimately should be able to liquidate the Failed Auction Security without significant loss primarily due to the overall quality of the issue held and the collateral securing the substantial majority of the underlying obligation. However, current conditions in the auction rate securities market have led management to conclude the recovery period for the Failed Auction Security exceeds 12 months. As a result, the Company continued to classify the Failed Auction Security as long-term as of March&#160;31, 2021. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Details of our investments are as follows (in thousands): </div></div> <div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

As such, the Company&#8217;s investment in the Failed Auction Security was deemed to require valuation using Level&#160;3 inputs. Management, after consulting with advisors, valued the Failed Auction Security using analyses and pricing models similar to those used by market participants (i.e., buyers, sellers, and the broker-dealers responsible for execution of the Dutch auction pricing mechanism by which each issue&#8217;s interest rate was set). Management utilized a probability weighted discounted cash flow (&#8220;DCF&#8221;) model to determine the estimated fair value of this security as of March&#160;31, 2021. The major assumptions used in preparing the DCF model were similar to those described in Note 5 - Fair Value Measurements in the Notes to the Consolidated Financial Statements contained in the Company&#8217;s 2020 Form <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">10-K.</div> </div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Quantitative information about Level&#160;3 fair value measurements as of March&#160;31, 2021 is as follows (dollars in thousands): </div></div> <div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

The benefit for income taxes for the three months ended March&#160;31, 2021 and 2020 included estimated foreign income taxes and estimated state taxes in jurisdictions in which the Company does not have sufficient net operating loss carryforwards. </div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;">As of March&#160;31, 2021, the Company had a valuation allowance of approximately $37,856,000 against all net domestic deferred tax assets, for which realization cannot be considered more likely than not at this time. Management assesses the need for the valuation allowance on a quarterly basis. In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and past financial performance. While recent positive operating results, as a result of increases in bookings, caused the Company to be in a cumulative income position as of March&#160;31, 2021, the Company faces uncertainties in forecasting its operating results due to the continued impact of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic on the Company&#8217;s supply chain, certain process issues with the production of Advanced Products and the unpredictability in certain markets. This operating uncertainty also makes it difficult to predict the availability and utilization of tax benefits over the next several years. As a result, management has concluded, at this time, it is more likely than not the Company&#8217;s net domestic deferred tax assets will not be realized, and a full valuation allowance against all net domestic deferred tax assets was still warranted as of March&#160;31, 2021. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. If the positive quarterly earnings and increases in bookings continue, and the Company&#8217;s concerns about industry uncertainty and world events, including the impact of the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic on the Company&#8217;s supply chain, and process issues with the production of Advanced Products are resolved, and the amount of tax benefits the Company is able to utilize to the point that the Company believes future taxable income can be more reliably forecasted, the Company may release all or a portion of the valuation allowance in the near-term. Certain state tax credits, though, will likely never be released by the valuation allowance. If and when the Company determines the valuation allowance should be released (i.e., reduced), the adjustment would result in a tax benefit reported in that period&#8217;s Consolidated Statements of Operations, the effect of which would be an increase in reported net income. </div><span></span>

In addition to these commitments, the Company had, in the aggregate, approximately $38,000,000 of remaining budgeted capital expenditures in 2021 associated with the construction of a 90,000 sq. ft. addition to the Company&#8217;s existing manufacturing facility and the installation of new production equipment. </div></div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company is the defendant in a patent infringement lawsuit originally filed on January&#160;28, 2011 by SynQor, Inc. (&#8220;SynQor&#8221;) in the U.S. District Court for the Eastern District of Texas (the &#8220;Texas Action&#8221;). The complaint, as amended, alleges that the Company&#8217;s products, including but not limited to, unregulated bus converters used in intermediate bus architecture power supply systems, infringe SynQor&#8217;s U.S. patent numbers 7,072,190, 7,272,021, 7,564,702, and 8,023,290 (&#8220;the &#8216;190 patent&#8221;, &#8220;the &#8216;021 patent&#8221;, &#8220;the &#8216;702 patent&#8221;, and &#8220;the &#8216;290 patent&#8221;, respectively). SynQor&#8217;s complaint sought an injunction against further infringement and an award of unspecified compensatory and enhanced damages, interest, costs and attorney fees. The Company has denied that its products infringe any of the SynQor patents, and has asserted that the SynQor patents are invalid and/or unenforceable. The Company has also asserted counterclaims seeking damages from SynQor for deceptive trade practices and tortious interference with prospective economic advantage arising from SynQor&#8217;s attempted enforcement of its patents against the Company. </div></div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On May&#160;23, 2016, after extensive discovery, the Texas Action was stayed by the court pending completion of certain inter partes reexamination (&#8220;IPRx&#8221;) proceedings at the United States Patent and Trademark Office (&#8220;USPTO&#8221;) (including any appeals from such proceedings to the Federal Circuit (as defined below)) concerning the SynQor patents, which are described below. That stay remains in force. On March&#160;17, 2021, SynQor filed a motion to lift the stay in the Texas Action. The Company has opposed that motion, which remains pending. </div></div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In 2011, in response to the filing of the Texas Action, the Company initiated IPRx proceedings at the USPTO challenging the validity of all claims that were asserted against the Company by SynQor. The current status of these proceedings is as follows. Regarding the &#8216;190 patent IPRx, the United States Court of Appeals for the Federal Circuit (the &#8220;Federal Circuit&#8221;) issued a decision on March&#160;13, 2015, determining that certain claims were invalid and remanding the matter to the Patent Trial and Appeal Board (&#8220;PTAB&#8221;) of the USPTO for further proceedings. On February&#160;20, 2019, the PTAB issued a decision finding that all of the remaining challenged claims were unpatentable. SynQor appealed that decision. On February&#160;22, 2021, the Federal Circuit issued a decision in that appeal. In a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">2-1</div> ruling, the Federal Circuit vacated and remanded the PTAB&#8217;s decision, finding that the reasoning the PTAB had relied on in reaching its decision was precluded by certain prior PTAB rulings regarding the &#8216;290 and &#8216;702 patents. On April&#160;7, 2021, the Company filed a petition for panel rehearing and rehearing <div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">en banc</div></div> of the Federal Circuit&#8217;s February&#160;22, 2021 decision. </div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On August&#160;30, 2017, the Federal Circuit issued rulings with regard to the IPRx proceedings for the &#8217;021, &#8216;702 and &#8216;290 patents. With respect to the &#8216;021 patent, the Federal Circuit affirmed the PTAB&#8217;s determination that all of the challenged claims of the &#8216;021 patent were invalid. The Federal Circuit remanded the case to the PTAB for further consideration of the patentability of certain claims that had been added by amendment during the reexamination. On February&#160;20, 2019, the PTAB issued a decision affirming the examiner&#8217;s rejections of all challenged claims. SynQor has filed an appeal of that decision in the Federal Circuit. That appeal has been stayed pending resolution of the pending appeal regarding the &#8216;190 patent IPRx. With respect to the &#8216;702 patent, the Federal Circuit affirmed the PTAB&#8217;s determination that all of the challenged claims of the &#8216;702 patent were patentable. With respect to the &#8216;290 patent, the Federal Circuit vacated the PTAB&#8217;s decision upholding the patentability of the &#8216;290 patent claims, and remanded the case to the PTAB for further consideration. On February&#160;20, 2019, the PTAB issued a decision reversing its prior affirmance of the examiner&#8217;s <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-adoption</div> of rejections with respect to the &#8216;290 patent, and entering rejections of all of the claims of the &#8216;290 patent. On May&#160;20, 2019, as permitted by USPTO rules, SynQor requested the USPTO to reopen prosecution of this proceeding to address the new rejections made by the PTAB. On September&#160;28, 2020, the examiner issued a decision reaffirming the PTAB&#8217;s rejection of all of the claims of the &#8216;290 patent. On March&#160;18, 2021, SynQor appealed this decision to the PTAB, which appeal remains pending. </div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On October&#160;31, 2017, the Company filed a request with the USPTO for ex parte reexamination (&#8220;EPRx&#8221;) of the asserted claims of the &#8216;702 patent, based on different prior art references than had been at issue in the previous IPRx of the &#8216;702 patent. On August&#160;6, 2018, the Company filed a similar request with the USPTO for EPRx of the asserted claims of the &#8216;190 patent, based on different prior art references than had been at issue in the previous IPRx of the &#8216;190 patent. On December&#160;18, 2020, the PTAB issued rulings upholding the validity of the asserted claims in the EPRx proceedings for both the &#8216;702 and &#8216;190 patents. Accordingly, both of those proceedings are now terminated. </div></div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">On January&#160;23, 2018, the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">20-year</div> terms of the &#8216;190 patent, the &#8216;021 patent, the &#8216;702 patent and the &#8216;290 patent expired. As a consequence of these expirations, the Company cannot be liable under any of the SynQor patents for allegedly infringing activities occurring after that date. In addition, any amended claims that may issue as a result of any of the still-pending reexamination proceedings will have no effective term and cannot be the basis for any liability by the Company. </div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company continues to believe none of its products, including its unregulated bus converters, infringe any valid claim of the asserted SynQor patents, either alone or when used in an intermediate bus architecture implementation. The Company believes SynQor&#8217;s claims lack merit and, therefore, it continues to vigorously defend itself against SynQor&#8217;s patent infringement allegations. The Company does not believe a loss is probable for this matter. If a loss were to be incurred, however, the Company cannot estimate the amount of possible loss or range of possible loss at this time. </div></div><div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div><div style="text-indent: 9%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In addition to the SynQor matter, the Company is involved in certain other litigation and claims incidental to the conduct of its business. While the outcome of lawsuits and claims against the Company cannot be predicted with certainty, management does not expect any current litigation or claims will have a material adverse impact on the Company&#8217;s financial position or results of operations. </div></div><span></span>
