$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 &#147;Failed Auction Security&#148;) since February 2008. 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.&nbsp;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 Security is presently at risk of default. Through September&nbsp;30, 2017, 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&nbsp;months. As a result, the Company continued to classify the Failed
Auction Security as long-term as of September&nbsp;30, 2017. </P> <P STYLE="font-size:12pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

types of estimated loss: an aggregate credit loss of $50,000 and an aggregate temporary impairment of $351,000. In determining the amount of credit loss, the Company compared the present value of cash flows expected to be collected to the amortized

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&#146;s interest rate was set). Management utilized a probability weighted discounted cash flow (&#147;DCF&#148;) model to determine the estimated fair value of this security as of
September&nbsp;30, 2017. The major assumptions used in preparing the DCF model included: estimates for the amount and timing of future interest and principal payments based on default probability assumptions used to measure the credit loss of 2.0%;
the rate of return required by investors to own this type of security in the current environment, which management estimates to be 5.0% above the risk free rate of return; and an estimated timeframe of three to five years for successful auctions for
this type of security to occur. In making these assumptions, management considered relevant factors including: the formula applicable to the security defining the interest rate paid to investors in the event of a failed auction (the &#147;Penalty
Rate&#148;); forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S.&nbsp;Department of Education of the
underlying student loans, guarantees by other third parties, and additional credit enhancements provided through other means; and publicly available pricing data for recently issued student loan asset-backed securities not subject to auctions. In

the security, management compared the Penalty Rate of the Failed Auction Security with yields of actively traded long-term bonds with similar characteristics and, reflecting the limited liquidity
for auction rate securities and the discounts to par value seen in recent tender offers by issuers and arm&#146;s length market transactions between informed buyers and sellers, estimated the implied yield (i.e., the discount to par value) necessary
to complete a sale of the Failed Auction Security. Management has calculated an increase or decrease in the liquidity risk premium of 5.0% referenced above of 1.0% (i.e., 100&nbsp;basis points) as used in the model, would decrease or increase,
respectively, the fair value of the Failed Auction Security by approximately $100,000. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The significant unobservable inputs
used in the fair value measurement of the Failed Auction Security are the cumulative probability of earning the maximum rate until maturity, the cumulative probability of principal return prior to maturity, the cumulative probability of default, the
liquidity risk premium, and the recovery rate in default.&nbsp;Significant increases (decreases) in any of those inputs in isolation would result in changes in fair value measurement. Significant increases (decreases) in the cumulative probability
of earning the maximum rate until maturity, the cumulative probability of principal return prior to maturity, and the recovery rate in default would result in a higher (lower) fair value measurement, while increases (decreases) in the cumulative
probability of default and the liquidity risk premium would result in a lower (higher) fair value measurement. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">Generally,
the interrelationships are such that a change in the assumption used for the cumulative probability of principal return prior to maturity is accompanied by a directionally similar change in the assumption used for the cumulative probability of
earning the maximum rate until maturity and a directionally opposite change in the assumptions used for the cumulative probability of default and the liquidity risk premium. The recovery rate in default is somewhat independent and based upon the
security&#146;s specific underlying assets and published recovery rate indices. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">Quantitative information about

lesser of the fair market value of a share of Common Stock on either the first day or the last day of that offering period. The purchase of shares is funded by means of periodic payroll deductions, which may not exceed 15.0% of the employee&#146;s

</TABLE> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On December&nbsp;31, 2010, the Company granted 2,984,250 <FONT STYLE="white-space:nowrap">non-qualified</FONT>
stock options under the VI Chip 2007 Stock Option and Incentive Plan with performance-based vesting provisions tied to achievement of certain margin targets by VI Chip Corporation. As of December&nbsp;31, 2010, the Company determined it was probable
the margin targets could be achieved and, accordingly, began recording stock-based compensation expense relating to these options beginning January&nbsp;1, 2011. During the third quarter of 2016, the Company determined the margin targets would not
be met prior to the expiration date of the corresponding options, as VI Chip&#146;s revenue growth has been below levels necessary to achieve the targets. As a result, in accordance with the accounting guidance for performance-based stock options,
the Company reversed approximately $768,000 of previously recorded stock-based compensation expense in the third quarter of 2016, representing all expense taken for these performance-based options through June&nbsp;30, 2016. This resulted in
decreases in cost of revenues of $86,000, selling, general and administrative expense of $516,000, and research and development expense of $166,000 for the three and nine months ended September&nbsp;30, 2016. </P>

the Company&#146;s warranty reserves include the number of units sold, historical and anticipated rates of warranty returns, and the cost per return. The Company periodically assesses the adequacy of warranty reserves and adjusts the amounts as

</TABLE> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The provisions for income taxes in each 2017 and 2016 period were primarily due to estimated
foreign income taxes and for estimated state taxes in jurisdictions in which the Company does not have net operating loss carryforwards. No tax benefit could be recognized for the majority of the Company&#146;s losses during the periods due to a
full valuation allowance against all net domestic deferred tax assets. In connection with the Company&#146;s acquisition of 100% ownership of certain operating assets and cash of the Company&#146;s consolidated subsidiary, Converpower Corporation,
the related deferred tax liability for unremitted earnings of $55,000 was reversed and recorded as a discrete benefit in the first quarter of 2016. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">As described in Note <FONT STYLE="white-space:nowrap">11-</FONT> Impact of Recently Issued Accounting Standards, the Company
adopted new guidance for employee share-based payment accounting during the first quarter of 2017. The new guidance, among other considerations, requires excess tax benefits and tax deficiencies related to employee share-based compensation to now be
recorded in earnings when the awards vest or are settled, rather than in shareholders&#146; equity under previous guidance. In addition, it eliminates the requirement that excess tax benefits be realized with the taxing authority before they can be
recognized. In connection with the adoption of this new guidance, the Company recorded a cumulative-effect adjustment as of January&nbsp;1, 2017 to increase gross deferred tax assets and the related valuation allowance against deferred tax assets by
$3,485,000. This amount was allocated and added to deferred tax assets for research and development tax credit carryforwards, net operating loss carryforwards and the alternative minimum tax credit carryforward but, as noted above, was fully offset
by a corresponding increase in the valuation allowance against deferred tax assets, resulting in no net effect on the Company&#146;s condensed consolidated financial statements. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">As of September&nbsp;30, 2017, the Company continues to maintain a valuation allowance of approximately $32,746,000 against all
domestic net deferred tax assets and the majority of foreign net deferred tax assets, for which realization cannot be considered more likely than not at this time. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In May 2017, the Company received notice from the Internal Revenue Service that its federal corporate tax return for tax year

(&#147;Ericsson&#148;), Cisco Systems, Inc. (&#147;Cisco&#148;) and the Company in the U.S. District Court for the Eastern District of Texas (the &#147;Texas Action&#148;). Ericsson and Cisco subsequently settled with SynQor and are no longer
parties to the Texas Action. With respect to the Company, SynQor&#146;s complaint in the Texas Action alleged that the Company&#146;s products, including but not limited to unregulated bus converters used in intermediate bus architecture power
supply systems, infringe SynQor&#146;s U.S. patent numbers 7,072,190, 7,272,021, and 7,564,702 (&#147;the &#145;190 patent&#148;, &#147;the &#145;021 patent&#148; and &#147;the &#145;702 patent&#148;, respectively). SynQor&#146;s complaint sought an
injunction against further infringement and an award of unspecified compensatory and enhanced damages, interest, costs and attorney fees. On September&nbsp;20, 2011, SynQor filed an amended complaint in the Texas Action that further alleged that the
Company&#146;s products, including, but not limited to, unregulated bus converters used in intermediate bus architecture power supply systems, infringe SynQor&#146;s U.S. patent number 8,023,290 (&#147;the &#145;290 patent&#148;). The Company
responded to SynQor&#146;s amended complaint in the Texas Action by denying its products infringe any of the SynQor patents, and asserting that the SynQor patents are invalid. The Company further alleged that the SynQor &#145;290 patent is
unenforceable due to inequitable conduct by SynQor or its agents during the examination of the &#145;290 patent at the United States Patent and Trademark Office (&#147;USPTO&#148;). The Company also asserted counterclaims seeking damages against
SynQor for deceptive trade practices and tortious interference with prospective economic advantage arising from SynQor&#146;s attempted enforcement of its patents against the Company. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">The Company initiated administrative review proceedings at the USPTO challenging the validity of certain claims of the SynQor patents asserted
in the Texas Action, including all claims that were asserted against the Company by SynQor. Regarding the &#145;190 patent, the Patent Trial and Appeal Board (&#147;PTAB&#148;) of the USPTO issued a decision upholding the validity of the &#145;190
patent claims. That decision was appealed by the Company to the United States Court of Appeals for the Federal Circuit (&#147;the Federal Circuit&#148;), which issued a decision on March&nbsp;13, 2015 reversing the PTAB, determining that certain
claims were invalid, and remanding the matter to the PTAB for further proceedings. On May&nbsp;2, 2016, the PTAB issued a decision determining that all but one of the remaining claims of the &#145;190 patent were invalid and remanding the remaining
claim to a patent examiner for further examination. On June&nbsp;22, 2017, the examiner issued a determination under 37 C.F.R. &#167; 41.77(d), finding that the remaining claim of the &#145;190 patent was unpatentable. That decision is expected to
be further reviewed by the PTAB pursuant to 37 C.F.R. &#167; 41.77(f). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">On May&nbsp;2, 2016, the PTAB also issued decisions finding all
challenged claims of SynQor&#146;s &#145;021 patent invalid and upholding the validity of all challenged claims of SynQor&#146;s &#145;702 and &#145;290 patents. On May&nbsp;23, 2016, the Texas Court issued an order staying the Texas Action until
the completion of all of the administrative review proceedings concerning the asserted SynQor patents, including any appeals from such proceedings to the Federal Circuit. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">On August&nbsp;30, 2017, the Federal Circuit issued rulings with regard to PTAB&#146;s reexamination decisions for the &#145;021, &#145;702
and &#145;290 patents. With respect to the &#145;021 patent, the Federal Circuit affirmed the PTAB&#146;s determination that all of the challenged claims of the &#145;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. With respect to the &#145;702 patent, the Federal Circuit affirmed the PTAB&#146;s determination that all of the challenged
claims of the &#145;702 patent were patentable. With respect to the &#145;290 patent, the Federal Circuit vacated the PTAB&#146;s decision upholding the patentability of the &#145;290 patent claims, and remanded the case to the PTAB for further
consideration. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">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&#146;s claims lack merit and, therefore, continues to vigorously defend itself against SynQor&#146;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. </P>

(&#147;BBU&#148;) designs, develops, manufactures and markets the Company&#146;s modular <FONT STYLE="white-space:nowrap">DC-DC</FONT> converters and configurable products, and also includes the entities comprising Vicor Custom Power and the BBU
operations of Vicor Japan Company, Ltd. (&#147;VJCL&#148;). The VI Chip segment includes VI Chip Corporation, which designs, develops, manufactures and markets many of the Company&#146;s advanced power component products. The VI Chip segment also
includes the VI Chip business conducted through VJCL. The Picor segment includes Picor Corporation, which designs, develops, manufactures and markets integrated circuits and related products for use in a variety of power management and power system
applications. The Picor segment develops these products for use in the Company&#146;s BBU and VI Chip modules, to be sold as complements to the Company&#146;s BBU and VI Chip products, or for sale to third parties for separate (i.e., stand-alone)
applications. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company&#146;s chief operating decision maker evaluates performance and allocates resources based on
segment revenues and segment operating income (loss). The operating income (loss) for each segment includes selling, general and administrative and research and development expenses directly attributable to the segment. Certain of the Company&#146;s
indirect overhead costs, which include corporate selling, general and administrative expenses, are allocated among the segments based upon an estimate of costs associated with each segment. Assets allocated to each segment are based upon specific
identification of such assets, which include accounts receivable, inventories, fixed assets and certain other assets. The Corporate segment consists of those operations and assets shared by all segments. The costs of certain centralized executive
and administrative functions are recorded in this segment, as are certain shared assets, most notably cash and cash equivalents, deferred tax assets, long-term investments, the Company&#146;s facilities in Massachusetts, real estate and other
assets. The Company&#146;s accounting policies and method of presentation for segments are consistent with that used throughout the Condensed Consolidated Financial Statements. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In May 2017, the Financial Accounting Standards Board (&#147;FASB&#148;) issued guidance about which changes to the terms or
conditions of a share-based payment award require an entity to apply modification accounting in Topic 718, <I>Compensation &#150; Stock Compensation</I>. The new guidance is effective for annual and interim periods beginning after December&nbsp;15,
2017, with early adoption permitted. The Company does not expect the adoption of the new guidance will have a material impact on its consolidated financial statements and related disclosures. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In August 2016, the FASB issued guidance to clarify how certain cash receipts and cash payments should be presented in the
statement of cash flows. These include debt prepayment, settlement of <FONT STYLE="white-space:nowrap">zero-coupon</FONT> debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of
insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investees and beneficial interests in securitization transactions. The new guidance is effective for interim and
annual reporting periods beginning after December&nbsp;15, 2017, with early adoption permitted. The Company does not expect the adoption of the new guidance will have a material impact on its consolidated financial statements and related
disclosures. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In June 2016, the FASB issued new guidance which will require measurement and recognition of expected credit
losses on certain types of financial instruments. It also modifies the impairment model for <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">available-for-sale</FONT></FONT> debt securities and provides for a simplified accounting
model for purchased financial assets with credit deterioration since their origination. The new guidance is effective for interim and annual reporting periods beginning after December&nbsp;15, 2019, with early adoption permitted. It is required to
be applied on a modified-retrospective approach with certain elements being adopted prospectively. The Company has not yet determined the impact this new guidance will have on its consolidated financial statements and related disclosures. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In March 2016, the FASB issued new guidance for employee share-based payment accounting, which makes several modifications to
existing guidance related to the accounting for forfeitures, employer tax withholding on share-based compensation and the financial statement presentation of excess tax benefits or deficiencies. This new guidance also clarifies the statement of cash
flows presentation for certain components of share-based awards. In terms of the accounting for forfeitures, the new guidance allows an option for them to either be estimated, as currently required, or recognized when they occur. The Company will
continue to estimate forfeitures. The Company adopted the new standard on January&nbsp;1, 2017. (See Note 8 &#150; Income Taxes for additional details on the impact of the adoption). </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In February 2016, the FASB issued new guidance for lease accounting, which will require lessees to recognize leases on the
balance sheet and disclose key information about leasing arrangements. The new guidance establishes a <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">right-of-use</FONT></FONT> model (&#147;ROU&#148;) that will require a lessee to
recognize a ROU asset and a lease liability on the balance sheet for all leases with a term longer than twelve months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense
recognition in the income statement. For lessors, the guidance modifies the classification criteria and accounting for sales-type and direct financing leases. The new standard is effective for interim and annual periods beginning after
December&nbsp;15, 2018, with early adoption permitted. The Company plans to adopt the new guidance effective January&nbsp;1, 2019. The new standard must be adopted using a modified retrospective transition which includes certain practical
expedients. The majority of the Company&#146;s leases are for certain of its office and manufacturing space. The Company has not yet determined the impact this new guidance will have on its consolidated financial statements and related disclosures.
</P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In May 2014, the FASB issued new guidance for revenue recognition, which will require an entity to recognize the amount of
revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new guidance, which includes several amendments, will replace most existing revenue recognition guidance in U.S. Generally Accepted
Accounting Principles when it becomes effective, which will be January&nbsp;1, 2018 for the Company. The new standard permits the use of either the retrospective or cumulative effect transition method. The Company has established an implementation
team to assess the potential impact of the new standard which includes identifying appropriate changes to the business processes, systems and controls to support revenue recognition and disclosure requirements under the new standard. While the
implementation team is still in the process of completing its evaluation of the new standard, it has reached preliminary conclusions on substantially all key accounting assessments, and currently believes the most significant impact will be related
to the timing of recognition of sales to its stocking distributors. The Company currently defers revenue and the related cost of sales on shipments to stocking distributors until the distributors resell the products to their customers. Upon adoption
of the new guidance, the Company will no </P>

identify forward-looking statements. Forward-looking statements include, without limitation, statements regarding the transition of the Company&#146;s business strategically and organizationally from serving a large number of relatively low volume
customers across diversified markets and geographies to serving a small number of relatively large volume customers, typically concentrated in computing and communications; the level of customer orders overall and, in particular, from large
customers and the delivery lead times associated therewith; the financial and operational impact of customer changes to shipping schedules; the derivation of a portion of the Company&#146;s sales in each quarter from orders booked in the same
quarter; the Company&#146;s ongoing development of power conversion architectures, switching topologies, packaging technologies, and products; the Company&#146;s plans to invest in expanded manufacturing capacity and the timing and location thereof;
the Company&#146;s continued success depending in part on its ability to attract and retain qualified personnel; the Company&#146;s belief that cash generated from operations and the total of its cash and cash equivalents will be sufficient to fund
operations for the foreseeable future; the Company&#146;s belief that it has limited exposure to currency risks; the Company&#146;s intentions regarding the declaration and payment of cash dividends; the Company&#146;s intentions regarding
protecting its rights under its patents; and the Company&#146;s expectation that no current litigation or claims will have a material adverse impact on its financial position or results of operations. These statements are based upon the
Company&#146;s current expectations and estimates as to the prospective events and circumstances which may or may not be within the Company&#146;s control and as to which there can be no assurance. Actual results could differ materially from those
expressed or implied by forward-looking statements as a result of various factors, including the Company&#146;s ability to: grow its revenues, establish and maintain profitability, develop and market new products and technologies cost effectively,
and on a timely basis leverage the Company&#146;s new technologies in standard products to promote market acceptance of the Company&#146;s new approach to power system architecture; leverage design wins into increased product sales; continue to meet
requirements of key customers and prospects; enter into licensing agreements increasing the Company&#146;s market opportunity and accelerating market penetration; realize significant royalties under such licensing agreements; achieve sustainable
bookings rates for the Company&#146;s products across served markets and geographies; improve manufacturing and operating efficiencies; successfully enforce the Company&#146;s intellectual property rights; successfully defend outstanding litigation;
hire and retain key personnel; and maintain an effective system of internal controls over financial reporting. These and other factors that may influence actual results are described in the risk factors set forth in the Company&#146;s Annual Report

BBU business conducted through VJCL and our Vicor Custom Power subsidiaries. The BBU has customers concentrated in aerospace and aviation, defense electronics, industrial automation and equipment, medical diagnostics, rail transportation, and test
and measurement instrumentation. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The VI Chip segment consists of our subsidiary, VI Chip Corporation, which designs, develops,
manufactures, and markets many of our advanced power component products. The VI Chip segment also includes VI Chip business conducted in Japan through VJCL. VI Chip generally targets large, high volume customers concentrated in the datacenter and
supercomputer segments of the computing market, although we also target applications in aerospace and aviation, defense electronics, electric and hybrid vehicles, instrumentation and test equipment, and networking equipment. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Picor segment consists of our subsidiary, Picor Corporation, which designs, develops, and markets integrated circuits and related
solid-state products for use in a variety of power management and power system applications. Picor is a &#147;fabless manufacturer,&#148; as its products are manufactured, assembled, packaged, and tested by third parties. Picor develops integrated
circuits for use in our BBU and VI Chip modules, to be sold as complements to our BBU and VI Chip products, or for sale to third parties for separate (i.e., stand-alone) applications, often integrated with VI Chip products to represent a customer
solution, particularly in the datacenter and supercomputer segments of the computing market. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our consolidated results for the third
quarter of 2017 showed sequential bottom-line improvement, with a reduced net loss despite a slight decline in net revenues, yet our operating performance continues to reflect the general weakness of demand for our legacy products, as well as
increased customer price sensitivity for these products. Customer interest in our expanding portfolio of recently-introduced advanced products continues to increase, as evidenced by the third quarter&#146;s higher bookings and sequentially higher <FONT
STYLE="white-space:nowrap">quarter-end</FONT> backlog, both reflecting market uptake of our new products, notably our 48 volt to <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">point-of-load</FONT></FONT> solutions for datacenters
and supercomputers. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">While improved third quarter bookings reflected increasing demand for our advanced products, with shipments scheduled
well into 2018, global demand for our legacy brick converters, configurable products, and associated components remains at volumes lower than historical trend, which we attribute to the ongoing macroeconomic conditions specific to the industries and
geographies we serve, as well as increased customer price sensitivity in certain industries and geographies in which commoditized products have established a strong competitive position. Our legacy products commonly are used in defense electronics,
high-value capital goods, and sizeable infrastructure projects, the end demand for which has been unpredictable, reflecting budgetary uncertainty and <FONT STYLE="white-space:nowrap">low-growth</FONT> economies. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Although the number of identified opportunities for our new products continues to expand, as evidenced by booking patterns, the sales cycles
associated with these products continue to be longer than we anticipated, in part due to the same macroeconomic trends and industry-specific conditions influencing bookings and sales of our legacy product lines. In many mature markets, existing and
potential customers remain risk-averse and have slowed or curtailed their own new product development. We believe such caution has limited their near-term interest in our new products, although we are experiencing increasing interest in our new
products as replacements for legacy power modules, whether our own or those of competitors, when customers are refreshing or upgrading existing designs. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In more robust markets, such as those we are targeting with our new products, existing and potential customers are actively pursuing their own
growth strategies, developing products with higher performance enabled by our new products and the modular component approach of our Factorized Power Architecture. As such, we increasingly are asked by existing and potential customers to collaborate
on the development of new or highly modified implementations of our new products. While such collaborations are attractive opportunities to enhance customer relationships and gain competitive advantage, they also are resource and time intensive.
Additionally, when we have successfully <FONT STYLE="white-space:nowrap">designed-in</FONT> our new product solutions, we may encounter delays and uncertainty associated with scheduling production of such solutions. For example, we are collaborating
with several large-scale OEMs in the datacenter segment of the computing market and have been engaged with these potential customers on development and design work for multiple quarters. However, only in the third quarter did we begin to receive <FONT
STYLE="white-space:nowrap">pre-production</FONT> prototype orders or early production orders associated with certain engagements. Given the number of such opportunities and the progress being made on associated development and design work, we expect
to receive more such early-stage orders from additional customers in the coming quarters. </P>

factory capacity, even with a high mix of products produced. However, periods of low volume production and/or brief, low volume production runs contribute to lower profitability, largely due to lower absorption of relatively high manufacturing
overhead costs associated with our manufacturing model. While direct labor and associated variable costs correlate with volume, manufacturing overhead costs are inflexible and, therefore, problematic during periods of low volume or brief production
runs. We have invested in the production capacity to meet our internal volume projections, and believe these projections are reasonable. However, if sustained, uniform, high volume production levels are not achieved, our product-level profitability
likely will not reach the levels necessary to cover our fixed spending, consisting of manufacturing overhead costs and operating costs. </TD></TR></TABLE> <P STYLE="font-size:6pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

components and other materials of proprietary design, our ability to sustain targeted production schedules and meet customer delivery requirements has been vulnerable to delays or shortages of such inventories. Over the last two years, we have made
progress in reducing potential vulnerabilities to stock-outs, vendor shortages, and similar supply chain disruptions. We also have reorganized our supply chain management effort, strengthened with new hires. We have implemented safety-stock programs
for certain critical components and materials and have established second-source supply relationships in order to reduce these vulnerabilities. However, our product-level profitability and overall performance could be negatively influenced by an
unplanned shortage of a particular component or material. </TD></TR></TABLE> <P STYLE="font-size:6pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

advanced products, and we believe our current level of spending is necessary to achieve our strategic goals. However, many of these opportunities are in early phases of development, and near-term revenue growth may not be sufficient to reduce the

third party for the former Westcor facility. Our exposure to market risk fluctuations in foreign currency exchange rates relate primarily to the operations of VJCL, for which the functional currency is the Japanese Yen. The functional currency of
all other subsidiaries in Europe and Asia is the U.S.&nbsp;Dollar. While our Vicor B.V. operation also potentially exposes us to exchange rate risk, as that subsidiary&#146;s sales are denominated in Euros and Pounds Sterling, any periodic gains or
losses associated with exchange rate fluctuations are small, given the small U.S.&nbsp;Dollar value of shipments we make to Vicor B.V. </P>

nine months ended September&nbsp;30, 2016 was primarily due to an overall 16.9% increase in bookings for the nine months ended September&nbsp;30, 2017, compared to the nine months ended September&nbsp;30, 2016. BBU, VI Chip, and Picor bookings
increased by 3.3%, 52.6% and 63.8%, respectively. The decrease in BBU revenues was primarily attributable to a decrease in BBU module and configurable product revenues of approximately $2,892,000, partially offset by an increase in Vicor Custom

taxes and for estimated state taxes in jurisdictions in which we do not have net operating loss carryforwards. No tax benefit could be recognized for the majority of our losses during the periods due to a full valuation allowance against all net
domestic deferred tax assets. In addition, in connection with our acquisition of 100% ownership of certain operating assets and cash of our consolidated subsidiary, Converpower Corporation, the related deferred tax liability for unremitted earnings
of $55,000 was reversed and recorded as a discrete benefit in the first quarter of 2016. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As described in Note <FONT
STYLE="white-space:nowrap">11-</FONT> Impact of Recently Issued Accounting Standards, we adopted new guidance for employee share-based payment accounting during the first quarter of 2017. The new guidance, among other considerations, requires excess
tax benefits and tax deficiencies related to employee share-based compensation to now be recorded in earnings when the awards vest or are settled, rather than in shareholders&#146; equity under previous guidance. In addition, it eliminates the
requirement that excess tax benefits be realized with the taxing authority before they can be recognized. In connection with the adoption of this new guidance, we recorded a cumulative-effect adjustment as of January&nbsp;1, 2017 to increase gross
deferred tax assets and the related valuation allowance against deferred tax assets by $3,485,000. This amount was allocated and added to deferred tax assets for research and development tax credit carryforwards, net operating loss carryforwards and
the alternative minimum tax credit carryforward but, as noted above, was fully offset by a corresponding increase in the valuation allowance against deferred tax assets, resulting in no net effect on our condensed consolidated financial statements.

Common Stock (the &#147;November 2000 Plan&#148;). 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 nine months ended September&nbsp;30, 2017. As of

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are exposed to a variety of market risks, including changes in interest rates affecting the return on our cash and cash equivalents and
fluctuations in foreign currency exchange rates. As our cash and cash equivalents consist principally of cash accounts and money market 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 September&nbsp;30, 2017, our long-term investment portfolio, recorded on our Condensed Consolidated Balance Sheet as &#147;Long-term investments, net&#148;, 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 &#147;Failed Auction Security&#148;) 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&#146;s default) are recorded through earnings as a component of &#147;Other income (expense), net&#148;, with the remainder of any periodic change in fair value not related to credit loss (i.e., temporary <FONT STYLE="white-space:nowrap"><FONT
STYLE="white-space:nowrap">&#147;mark-to-market&#148;</FONT></FONT> carrying value adjustments) recorded in &#147;Accumulated other comprehensive (loss) income&#148;, a component of Stockholders&#146; 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 &#147;Other income (expense), net&#148;. We do not believe there was an &#147;other-than-temporary&#148; decline in value
in this security as of September&nbsp;30, 2017. </P> <P STYLE="margin-top:10pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our exposure to market risk for fluctuations in foreign currency exchange rates relates
primarily 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.&nbsp;Dollar. As the functional currency of all other subsidiaries in Europe and other subsidiaries
in Asia is the U.S.&nbsp;Dollar, we believe risk to fluctuations in foreign currency exchange rates is not significant, as these operations do not incur material foreign exchange exposures. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As required by <FONT STYLE="white-space:nowrap">Rule&nbsp;13a-15</FONT> under the Securities Exchange Act of 1934, as amended (the
&#147;Exchange Act&#148;), management, with the participation of our Chief Executive Officer (&#147;CEO&#148;) (who is our principal executive officer) and Chief Financial Officer (&#147;CFO&#148;) (who is our principal financial officer), conducted
an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the last fiscal quarter (i.e., September&nbsp;30, 2017). The term &#147;disclosure controls and procedures,&#148; as defined in <FONT
STYLE="white-space:nowrap">Rules&nbsp;13a-15(e)</FONT> and <FONT STYLE="white-space:nowrap">15d-15(e)</FONT> 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&#146;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&#146;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 September&nbsp;30, 2017, our CEO and CFO concluded, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level. </P>
<P STYLE="margin-top:10pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control
system&#146;s objectives will be met. Accordingly, management, including the CEO and CFO, 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. The design of any
system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any
control&#146;s effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. </P>

 On January&amp;#xA0;28, 2011, SynQor, Inc. (&amp;#x201C;SynQor&amp;#x201D;) filed
 a complaint for patent infringement against Ericsson, Inc.
 (&amp;#x201C;Ericsson&amp;#x201D;), Cisco Systems, Inc. (&amp;#x201C;Cisco&amp;#x201D;)
 and the Company in the U.S. District Court for the Eastern District
 of Texas (the &amp;#x201C;Texas Action&amp;#x201D;). Ericsson and Cisco
 subsequently settled with SynQor and are no longer parties to the
 Texas Action. With respect to the Company, SynQor&amp;#x2019;s complaint
 in the Texas Action alleged that the Company&amp;#x2019;s products,
 including but not limited to unregulated bus converters used in
 intermediate bus architecture power supply systems, infringe
 SynQor&amp;#x2019;s U.S. patent numbers 7,072,190, 7,272,021, and
 7,564,702 (&amp;#x201C;the &amp;#x2018;190 patent&amp;#x201D;, &amp;#x201C;the
 &amp;#x2018;021 patent&amp;#x201D; and &amp;#x201C;the &amp;#x2018;702 patent&amp;#x201D;,
 respectively). SynQor&amp;#x2019;s complaint sought an injunction
 against further infringement and an award of unspecified
 compensatory and enhanced damages, interest, costs and attorney
 fees. On September&amp;#xA0;20, 2011, SynQor filed an amended complaint
 in the Texas Action that further alleged that the Company&amp;#x2019;s
 products, including, but not limited to, unregulated bus converters
 used in intermediate bus architecture power supply systems,
 infringe SynQor&amp;#x2019;s U.S. patent number 8,023,290 (&amp;#x201C;the
 &amp;#x2018;290 patent&amp;#x201D;). The Company responded to SynQor&amp;#x2019;s
 amended complaint in the Texas Action by denying its products
 infringe any of the SynQor patents, and asserting that the SynQor
 patents are invalid. The Company further alleged that the SynQor
 &amp;#x2018;290 patent is unenforceable due to inequitable conduct by
 SynQor or its agents during the examination of the &amp;#x2018;290
 patent at the United States Patent and Trademark Office
 (&amp;#x201C;USPTO&amp;#x201D;). The Company also asserted counterclaims
 seeking damages against SynQor for deceptive trade practices and
 tortious interference with prospective economic advantage arising
 from SynQor&amp;#x2019;s attempted enforcement of its patents against
 the Company.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman"&gt;
 The Company initiated administrative review proceedings at the
 USPTO challenging the validity of certain claims of the SynQor
 patents asserted in the Texas Action, including all claims that
 were asserted against the Company by SynQor. Regarding the
 &amp;#x2018;190 patent, the Patent Trial and Appeal Board
 (&amp;#x201C;PTAB&amp;#x201D;) of the USPTO issued a decision upholding the
 validity of the &amp;#x2018;190 patent claims. That decision was
 appealed by the Company to the United States Court of Appeals for
 the Federal Circuit (&amp;#x201C;the Federal Circuit&amp;#x201D;), which
 issued a decision on March&amp;#xA0;13, 2015 reversing the PTAB,
 determining that certain claims were invalid, and remanding the
 matter to the PTAB for further proceedings. On May&amp;#xA0;2, 2016,
 the PTAB issued a decision determining that all but one of the
 remaining claims of the &amp;#x2018;190 patent were invalid and
 remanding the remaining claim to a patent examiner for further
 examination. On June&amp;#xA0;22, 2017, the examiner issued a
 determination under 37 C.F.R. &amp;#xA7; 41.77(d), finding that the
 remaining claim of the &amp;#x2018;190 patent was unpatentable. That
 decision is expected to be further reviewed by the PTAB pursuant to
 37 C.F.R. &amp;#xA7; 41.77(f).&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman"&gt;
 On May&amp;#xA0;2, 2016, the PTAB also issued decisions finding all
 challenged claims of SynQor&amp;#x2019;s &amp;#x2018;021 patent invalid and
 upholding the validity of all challenged claims of SynQor&amp;#x2019;s
 &amp;#x2018;702 and &amp;#x2018;290 patents. On May&amp;#xA0;23, 2016, the Texas
 Court issued an order staying the Texas Action until the completion
 of all of the administrative review proceedings concerning the
 asserted SynQor patents, including any appeals from such
 proceedings to the Federal Circuit.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman"&gt;
 On August&amp;#xA0;30, 2017, the Federal Circuit issued rulings with
 regard to PTAB&amp;#x2019;s reexamination decisions for the &amp;#x2018;021,
 &amp;#x2018;702 and &amp;#x2018;290 patents. With respect to the &amp;#x2018;021
 patent, the Federal Circuit affirmed the PTAB&amp;#x2019;s determination
 that all of the challenged claims of the &amp;#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. With respect
 to the &amp;#x2018;702 patent, the Federal Circuit affirmed the
 PTAB&amp;#x2019;s determination that all of the challenged claims of the
 &amp;#x2018;702 patent were patentable. With respect to the &amp;#x2018;290
 patent, the Federal Circuit vacated the PTAB&amp;#x2019;s decision
 upholding the patentability of the &amp;#x2018;290 patent claims, and
 remanded the case to the PTAB for further consideration.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman"&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&amp;#x2019;s claims lack merit and, therefore, continues to
 vigorously defend itself against SynQor&amp;#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;/p&gt;
 &lt;p style="font-size:1px;margin-top:6px;margin-bottom:0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="margin-top:0pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman"&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&amp;#x2019;s financial position or results
 of operations.&lt;/p&gt;

 The Company&amp;#x2019;s Board of Directors approved the Vicor
 Corporation 2017 Employee Stock Purchase Plan (the
 &amp;#x201C;Plan&amp;#x201D; or the &amp;#x201C;ESPP&amp;#x201D;) on April&amp;#xA0;26,
 2017. The ESPP became effective on June&amp;#xA0;16, 2017, the date the
 Company&amp;#x2019;s stockholders approved the Plan at the 2017 Annual
 Meeting of Stockholders. The Company has reserved 2,000,000 shares
 of Common Stock under the Plan for issuance to eligible employees
 who elect to participate. The ESPP is intended to qualify as an
 &amp;#x201C;employee stock purchase plan&amp;#x201D; under Section&amp;#xA0;423
 of the Internal Revenue Code. The ESPP operates in successive
 periods of approximately six months, each referred to as an
 &amp;#x201C;offering period.&amp;#x201D; Generally, offering periods commence
 on or around September&amp;#xA0;1 and March&amp;#xA0;1 and end on or around
 the following February&amp;#xA0;28 or August&amp;#xA0;31, respectively.
 Under the ESPP, an option is granted to participating employees on
 the first day of an offering period to purchase shares of the
 Company&amp;#x2019;s Common Stock at the end of that offering period at
 a purchase price equal to 85% of the lesser of the fair market
 value of a share of Common Stock on either the first day or the
 last day of that offering period. The purchase of shares is funded
 by means of periodic payroll deductions, which may not exceed 15.0%
 of the employee&amp;#x2019;s eligible compensation, as defined in the
 Plan. Among other provisions, the Plan limits the number of shares
 that can be purchased by a participant during any offering period
 and cumulatively for any calendar year.&lt;/p&gt;

 The Company uses the Black-Scholes option pricing model to
 calculate the fair value of stock option awards and options granted
 under the ESPP as of their grant date. Stock-based compensation

 On December&amp;#xA0;31, 2010, the Company granted
 2,984,250&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;non-qualified&lt;/font&gt;&amp;#xA0;stock
 options under the VI Chip 2007 Stock Option and Incentive Plan with
 performance-based vesting provisions tied to achievement of certain
 margin targets by VI Chip Corporation. As of December&amp;#xA0;31,
 2010, the Company determined it was probable the margin targets
 could be achieved and, accordingly, began recording stock-based
 compensation expense relating to these options beginning
 January&amp;#xA0;1, 2011. During the third quarter of 2016, the Company
 determined the margin targets would not be met prior to the
 expiration date of the corresponding options, as VI Chip&amp;#x2019;s
 revenue growth has been below levels necessary to achieve the
 targets. As a result, in accordance with the accounting guidance
 for performance-based stock options, the Company reversed
 approximately $768,000 of previously recorded stock-based
 compensation expense in the third quarter of 2016, representing all
 expense taken for these performance-based options through
 June&amp;#xA0;30, 2016. This resulted in decreases in cost of revenues
 of $86,000, selling, general and administrative expense of
 $516,000, and research and development expense of $166,000 for the
 three and nine months ended September&amp;#xA0;30, 2016.&lt;/p&gt;

 The Company accounts for certain financial assets at fair value,
 defined as the price that would be received to sell an asset or
 paid to transfer a liability (i.e., an exit price) in the principal
 or most advantageous market for the asset or liability in an
 orderly transaction between market participants on the measurement
 date. As such, fair value is a market-based measurement that should
 be determined based on assumptions market participants would use in
 pricing an asset or liability. A three-level hierarchy is used to
 show the extent and level of judgment used to estimate fair value
 measurements.&lt;/p&gt;

 As of September&amp;#xA0;30, 2017, there was insufficient observable
 auction rate security market information available to determine the
 fair value of the Failed Auction Security using Level&amp;#xA0;1 or
 Level&amp;#xA0;2 inputs. As such, the Company&amp;#x2019;s investment in the
 Failed Auction Security was deemed to require valuation using
 Level&amp;#xA0;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&amp;#x2019;s
 interest rate was set). Management utilized a probability weighted
 discounted cash flow (&amp;#x201C;DCF&amp;#x201D;) model to determine the
 estimated fair value of this security as of September&amp;#xA0;30,
 2017. The major assumptions used in preparing the DCF model
 included: estimates for the amount and timing of future interest
 and principal payments based on default probability assumptions
 used to measure the credit loss of 2.0%; the rate of return
 required by investors to own this type of security in the current
 environment, which management estimates to be 5.0% above the risk
 free rate of return; and an estimated timeframe of three to five
 years for successful auctions for this type of security to occur.
 In making these assumptions, management considered relevant factors
 including: the formula applicable to the security defining the
 interest rate paid to investors in the event of a failed auction
 (the &amp;#x201C;Penalty Rate&amp;#x201D;); forward projections of the
 interest rate benchmarks specified in such formulas; the likely
 timing of principal repayments; the probability of full repayment
 considering the guarantees by the U.S.&amp;#xA0;Department of Education
 of the underlying student loans, guarantees by other third parties,
 and additional credit enhancements provided through other means;
 and publicly available pricing data for recently issued student
 loan asset-backed securities not subject to auctions. In developing
 its estimate of the rate of return required by investors to own the
 security, management compared the Penalty Rate of the Failed
 Auction Security with yields of actively traded long-term bonds
 with similar characteristics and, reflecting the limited liquidity
 for auction rate securities and the discounts to par value seen in
 recent tender offers by issuers and arm&amp;#x2019;s length market
 transactions between informed buyers and sellers, estimated the
 implied yield (i.e., the discount to par value) necessary to
 complete a sale of the Failed Auction Security. Management has
 calculated an increase or decrease in the liquidity risk premium of
 5.0% referenced above of 1.0% (i.e., 100&amp;#xA0;basis points) as used
 in the model, would decrease or increase, respectively, the fair
 value of the Failed Auction Security by approximately $100,000.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The significant unobservable inputs used in the fair value
 measurement of the Failed Auction Security are the cumulative
 probability of earning the maximum rate until maturity, the
 cumulative probability of principal return prior to maturity, the
 cumulative probability of default, the liquidity risk premium, and
 the recovery rate in default.&amp;#xA0;Significant increases
 (decreases) in any of those inputs in isolation would result in
 changes in fair value measurement. Significant increases
 (decreases) in the cumulative probability of earning the maximum
 rate until maturity, the cumulative probability of principal return
 prior to maturity, and the recovery rate in default would result in
 a higher (lower) fair value measurement, while increases
 (decreases) in the cumulative probability of default and the
 liquidity risk premium would result in a lower (higher) fair value
 measurement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Generally, the interrelationships are such that a change in the
 assumption used for the cumulative probability of principal return
 prior to maturity is accompanied by a directionally similar change
 in the assumption used for the cumulative probability of earning
 the maximum rate until maturity and a directionally opposite change
 in the assumptions used for the cumulative probability of default
 and the liquidity risk premium. The recovery rate in default is
 somewhat independent and based upon the security&amp;#x2019;s specific
 underlying assets and published recovery rate indices.&lt;/p&gt;

 &lt;p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The provisions for income taxes in each 2017 and 2016 period were
 primarily due to estimated foreign income taxes and for estimated
 state taxes in jurisdictions in which the Company does not have net
 operating loss carryforwards. No tax benefit could be recognized
 for the majority of the Company&amp;#x2019;s losses during the periods
 due to a full valuation allowance against all net domestic deferred
 tax assets. In connection with the Company&amp;#x2019;s acquisition of
 100% ownership of certain operating assets and cash of the
 Company&amp;#x2019;s consolidated subsidiary, Converpower Corporation,
 the related deferred tax liability for unremitted earnings of
 $55,000 was reversed and recorded as a discrete benefit in the
 first quarter of 2016.&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 As described in Note &lt;font style="white-space:nowrap"&gt;11-&lt;/font&gt;
 Impact of Recently Issued Accounting Standards, the Company adopted
 new guidance for employee share-based payment accounting during the
 first quarter of 2017. The new guidance, among other
 considerations, requires excess tax benefits and tax deficiencies
 related to employee share-based compensation to now be recorded in
 earnings when the awards vest or are settled, rather than in
 shareholders&amp;#x2019; equity under previous guidance. In addition, it
 eliminates the requirement that excess tax benefits be realized
 with the taxing authority before they can be recognized. In
 connection with the adoption of this new guidance, the Company
 recorded a cumulative-effect adjustment as of January&amp;#xA0;1, 2017
 to increase gross deferred tax assets and the related valuation
 allowance against deferred tax assets by $3,485,000. This amount
 was allocated and added to deferred tax assets for research and
 development tax credit carryforwards, net operating loss
 carryforwards and the alternative minimum tax credit carryforward
 but, as noted above, was fully offset by a corresponding increase
 in the valuation allowance against deferred tax assets, resulting
 in no net effect on the Company&amp;#x2019;s condensed consolidated
 financial statements.&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 As of September&amp;#xA0;30, 2017, the Company continues to maintain a
 valuation allowance of approximately $32,746,000 against all
 domestic net deferred tax assets and the majority of foreign net
 deferred tax assets, for which realization cannot be considered
 more likely than not at this time.&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 In May 2017, the Company received notice from the Internal Revenue
 Service that its federal corporate tax return for tax year 2015 had
 been selected for examination. The examination is ongoing.&lt;/p&gt;

 As of September&amp;#xA0;30, 2017 and December&amp;#xA0;31, 2016, the
 Company held one 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 &amp;#x201C;Failed Auction
 Security&amp;#x201D;) since February 2008. 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.&amp;#xA0;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 Security is presently at
 risk of default. Through September&amp;#xA0;30, 2017, 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&amp;#xA0;months. As a result, the Company continued
 to classify the Failed Auction Security as long-term as of
 September&amp;#xA0;30, 2017.&lt;/p&gt;

 As of September&amp;#xA0;30, 2017, the Failed Auction Security had been
 in an unrealized loss position for greater than 12 months.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Based on the fair value measurements described in Note&amp;#xA0;3, the
 fair value of the Failed Auction Security on September&amp;#xA0;30,
 2017, with a par value of $3,000,000, was estimated by the Company
 to be approximately $2,599,000. The gross unrealized loss of
 $401,000 on the Failed Auction Security consists of two types of
 estimated loss: an aggregate credit loss of $50,000 and an
 aggregate temporary impairment of $351,000. 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 (See Note&amp;#xA0;3).&lt;/p&gt;

 At this time, the Company has no intent to sell the impaired Failed
 Auction Security and does not believe it is more likely than not
 the Company will be required to sell this security. If current
 market conditions deteriorate further, the Company may be required
 to record additional unrealized losses. If the credit rating of the
 security deteriorates, the Company may be required to adjust the
 carrying value of the investment through impairment charges
 recorded in the Condensed Consolidated Statements of Operations,
 and any such impairment adjustments may be material.&lt;/p&gt;

 Based on the Company&amp;#x2019;s ability to access cash and cash
 equivalents and its expected operating cash flows, management does
 not anticipate the current lack of liquidity associated with the
 Failed Auction Security held will affect the Company&amp;#x2019;s
 ability to execute its current operating plan.&lt;/p&gt;

 &lt;p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 Inventories are valued at the lower of cost (determined using the
 &lt;font style="white-space:nowrap"&gt;first-in,&lt;/font&gt; &lt;font style="white-space:nowrap"&gt;first-out&lt;/font&gt; method) or net realizable
 value. Fixed production overhead is allocated to the inventory cost
 per unit based on the normal capacity of the production facilities.
 Abnormal production costs, including fixed cost variances from
 normal production capacity, if any, are charged to cost of revenues
 in the period incurred. All shipping and handling costs incurred in
 connection with the sale of products are included in cost of
 revenues.&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The Company provides reserves for inventories estimated to be
 excess, obsolete or unmarketable. The Company&amp;#x2019;s estimation
 process for assessing net realizable value is based upon its known
 backlog, projected future demand, historical consumption and
 expected market conditions. If the Company&amp;#x2019;s estimated demand
 and/or market expectation were to change or if product sales were
 to decline, the Company&amp;#x2019;s estimation process may cause larger
 inventory reserves to be recorded, resulting in larger charges to
 cost of revenues.&lt;/p&gt;

 11. &lt;u&gt;Impact of Recently Issued Accounting Standards&lt;/u&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In May 2017, the Financial Accounting Standards Board
 (&amp;#x201C;FASB&amp;#x201D;) issued guidance about which changes to the
 terms or conditions of a share-based payment award require an
 entity to apply modification accounting in Topic 718,
 &lt;i&gt;Compensation &amp;#x2013; Stock Compensation&lt;/i&gt;. The new guidance is
 effective for annual and interim periods beginning after
 December&amp;#xA0;15, 2017, with early adoption permitted. The Company
 does not expect the adoption of the new guidance will have a
 material impact on its consolidated financial statements and
 related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In August 2016, the FASB issued guidance to clarify how certain
 cash receipts and cash payments should be presented in the
 statement of cash flows. These include debt prepayment, settlement
 of &lt;font style="WHITE-SPACE: nowrap"&gt;zero-coupon&lt;/font&gt; debt
 instruments, contingent consideration payments made after a
 business combination, proceeds from the settlement of insurance
 claims, proceeds from the settlement of corporate-owned life
 insurance policies, distributions received from equity method
 investees and beneficial interests in securitization transactions.
 The new guidance is effective for interim and annual reporting
 periods beginning after December&amp;#xA0;15, 2017, with early adoption
 permitted. The Company does not expect the adoption of the new
 guidance will have a material impact on its consolidated financial
 statements and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In June 2016, the FASB issued new guidance which will require
 measurement and recognition of expected credit losses on certain
 types of financial instruments. It also modifies the impairment
 model for &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;available-for-sale&lt;/font&gt;&lt;/font&gt; debt
 securities and provides for a simplified accounting model for
 purchased financial assets with credit deterioration since their
 origination. The new guidance is effective for interim and annual
 reporting periods beginning after December&amp;#xA0;15, 2019, with
 early adoption permitted. It is required to be applied on a
 modified-retrospective approach with certain elements being adopted
 prospectively. The Company has not yet determined the impact this
 new guidance will have on its consolidated financial statements and
 related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In March 2016, the FASB issued new guidance for employee
 share-based payment accounting, which makes several modifications
 to existing guidance related to the accounting for forfeitures,
 employer tax withholding on share-based compensation and the
 financial statement presentation of excess tax benefits or
 deficiencies. This new guidance also clarifies the statement of
 cash flows presentation for certain components of share-based
 awards. In terms of the accounting for forfeitures, the new
 guidance allows an option for them to either be estimated, as
 currently required, or recognized when they occur. The Company will
 continue to estimate forfeitures. The Company adopted the new
 standard on January&amp;#xA0;1, 2017. (See Note 8 &amp;#x2013; Income Taxes
 for additional details on the impact of the adoption).&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In February 2016, the FASB issued new guidance for lease
 accounting, which will require lessees to recognize leases on the
 balance sheet and disclose key information about leasing
 arrangements. The new guidance establishes a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;right-of-use&lt;/font&gt;&lt;/font&gt; model
 (&amp;#x201C;ROU&amp;#x201D;) that will require a lessee to recognize a ROU
 asset and a lease liability on the balance sheet for all leases
 with a term longer than twelve months. Leases will be classified as
 finance or operating, with classification affecting the pattern and
 classification of expense recognition in the income statement. For
 lessors, the guidance modifies the classification criteria and
 accounting for sales-type and direct financing leases. The new
 standard is effective for interim and annual periods beginning
 after December&amp;#xA0;15, 2018, with early adoption permitted. The
 Company plans to adopt the new guidance effective January&amp;#xA0;1,
 2019. The new standard must be adopted using a modified
 retrospective transition which includes certain practical
 expedients. The majority of the Company&amp;#x2019;s leases are for
 certain of its office and manufacturing space. The Company has not
 yet determined the impact this new guidance will have on its
 consolidated financial statements and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In May 2014, the FASB issued new guidance for revenue recognition,
 which will require an entity to recognize the amount of revenue to
 which it expects to be entitled for the transfer of promised goods
 or services to customers. The new guidance, which includes several
 amendments, will replace most existing revenue recognition guidance
 in U.S. Generally Accepted Accounting Principles when it becomes
 effective, which will be January&amp;#xA0;1, 2018 for the Company. The
 new standard permits the use of either the retrospective or
 cumulative effect transition method. The Company has established an
 implementation team to assess the potential impact of the new
 standard which includes identifying appropriate changes to the
 business processes, systems and controls to support revenue
 recognition and disclosure requirements under the new standard.
 While the implementation team is still in the process of completing
 its evaluation of the new standard, it has reached preliminary
 conclusions on substantially all key accounting assessments, and
 currently believes the most significant impact will be related to
 the timing of recognition of sales to its stocking distributors.
 The Company currently defers revenue and the related cost of sales
 on shipments to stocking distributors until the distributors resell
 the products to their customers. Upon adoption of the new guidance,
 the Company will no longer be permitted to defer revenue until sale
 by the stocking distributor to the end customer, but rather, will
 be required to estimate the effects of returns and allowances
 provided to stocking distributors and record revenue at the time of
 sale to the stocking distributor. The Company currently plans to
 utilize the retrospective transition method for adoption of the
 standard. Upon adoption under that method, the Company will
 recognize the cumulative effect of adopting this guidance as an
 adjustment to the balance of retained earnings as of
 January&amp;#xA0;1, 2016. The implementation team is continuing to
 evaluate the method of adoption and the future impact the new
 guidance will have on its consolidated financial statements and
 related disclosures and expects to complete its assessment of those
 financial statement impacts during the fourth quarter of 2017. The
 other principal remaining implementation items include completing
 the identification and documentation of key transition controls
 and, later, the identification and documentation of any new or
 revised key ongoing process controls. The implementation team
 expects to complete those tasks by the end of the fourth quarter of
 2017. The implementation team has reported its findings and status
 to the Audit Committee on a regular basis over the last
 year.&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Other new pronouncements issued but not effective until after
 September&amp;#xA0;30, 2017 are not expected to have a material impact

 In May 2017, the Financial Accounting Standards Board
 (&amp;#x201C;FASB&amp;#x201D;) issued guidance about which changes to the
 terms or conditions of a share-based payment award require an
 entity to apply modification accounting in Topic 718,
 &lt;i&gt;Compensation &amp;#x2013; Stock Compensation&lt;/i&gt;. The new guidance is
 effective for annual and interim periods beginning after
 December&amp;#xA0;15, 2017, with early adoption permitted. The Company
 does not expect the adoption of the new guidance will have a
 material impact on its consolidated financial statements and
 related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In August 2016, the FASB issued guidance to clarify how certain
 cash receipts and cash payments should be presented in the
 statement of cash flows. These include debt prepayment, settlement
 of &lt;font style="WHITE-SPACE: nowrap"&gt;zero-coupon&lt;/font&gt; debt
 instruments, contingent consideration payments made after a
 business combination, proceeds from the settlement of insurance
 claims, proceeds from the settlement of corporate-owned life
 insurance policies, distributions received from equity method
 investees and beneficial interests in securitization transactions.
 The new guidance is effective for interim and annual reporting
 periods beginning after December&amp;#xA0;15, 2017, with early adoption
 permitted. The Company does not expect the adoption of the new
 guidance will have a material impact on its consolidated financial
 statements and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In June 2016, the FASB issued new guidance which will require
 measurement and recognition of expected credit losses on certain
 types of financial instruments. It also modifies the impairment
 model for &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;available-for-sale&lt;/font&gt;&lt;/font&gt; debt
 securities and provides for a simplified accounting model for
 purchased financial assets with credit deterioration since their
 origination. The new guidance is effective for interim and annual
 reporting periods beginning after December&amp;#xA0;15, 2019, with
 early adoption permitted. It is required to be applied on a
 modified-retrospective approach with certain elements being adopted
 prospectively. The Company has not yet determined the impact this
 new guidance will have on its consolidated financial statements and
 related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In March 2016, the FASB issued new guidance for employee
 share-based payment accounting, which makes several modifications
 to existing guidance related to the accounting for forfeitures,
 employer tax withholding on share-based compensation and the
 financial statement presentation of excess tax benefits or
 deficiencies. This new guidance also clarifies the statement of
 cash flows presentation for certain components of share-based
 awards. In terms of the accounting for forfeitures, the new
 guidance allows an option for them to either be estimated, as
 currently required, or recognized when they occur. The Company will
 continue to estimate forfeitures. The Company adopted the new
 standard on January&amp;#xA0;1, 2017. (See Note 8 &amp;#x2013; Income Taxes
 for additional details on the impact of the adoption).&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In February 2016, the FASB issued new guidance for lease
 accounting, which will require lessees to recognize leases on the
 balance sheet and disclose key information about leasing
 arrangements. The new guidance establishes a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;right-of-use&lt;/font&gt;&lt;/font&gt; model
 (&amp;#x201C;ROU&amp;#x201D;) that will require a lessee to recognize a ROU
 asset and a lease liability on the balance sheet for all leases
 with a term longer than twelve months. Leases will be classified as
 finance or operating, with classification affecting the pattern and
 classification of expense recognition in the income statement. For
 lessors, the guidance modifies the classification criteria and
 accounting for sales-type and direct financing leases. The new
 standard is effective for interim and annual periods beginning
 after December&amp;#xA0;15, 2018, with early adoption permitted. The
 Company plans to adopt the new guidance effective January&amp;#xA0;1,
 2019. The new standard must be adopted using a modified
 retrospective transition which includes certain practical
 expedients. The majority of the Company&amp;#x2019;s leases are for
 certain of its office and manufacturing space. The Company has not
 yet determined the impact this new guidance will have on its
 consolidated financial statements and related disclosures.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In May 2014, the FASB issued new guidance for revenue recognition,
 which will require an entity to recognize the amount of revenue to
 which it expects to be entitled for the transfer of promised goods
 or services to customers. The new guidance, which includes several
 amendments, will replace most existing revenue recognition guidance
 in U.S. Generally Accepted Accounting Principles when it becomes
 effective, which will be January&amp;#xA0;1, 2018 for the Company. The
 new standard permits the use of either the retrospective or
 cumulative effect transition method. The Company has established an
 implementation team to assess the potential impact of the new
 standard which includes identifying appropriate changes to the
 business processes, systems and controls to support revenue
 recognition and disclosure requirements under the new standard.
 While the implementation team is still in the process of completing
 its evaluation of the new standard, it has reached preliminary
 conclusions on substantially all key accounting assessments, and
 currently believes the most significant impact will be related to
 the timing of recognition of sales to its stocking distributors.
 The Company currently defers revenue and the related cost of sales
 on shipments to stocking distributors until the distributors resell
 the products to their customers. Upon adoption of the new guidance,
 the Company will no longer be permitted to defer revenue until sale
 by the stocking distributor to the end customer, but rather, will
 be required to estimate the effects of returns and allowances
 provided to stocking distributors and record revenue at the time of
 sale to the stocking distributor. The Company currently plans to
 utilize the retrospective transition method for adoption of the
 standard. Upon adoption under that method, the Company will
 recognize the cumulative effect of adopting this guidance as an
 adjustment to the balance of retained earnings as of
 January&amp;#xA0;1, 2016. The implementation team is continuing to
 evaluate the method of adoption and the future impact the new
 guidance will have on its consolidated financial statements and
 related disclosures and expects to complete its assessment of those
 financial statement impacts during the fourth quarter of 2017. The
 other principal remaining implementation items include completing
 the identification and documentation of key transition controls
 and, later, the identification and documentation of any new or
 revised key ongoing process controls. The implementation team
 expects to complete those tasks by the end of the fourth quarter of
 2017. The implementation team has reported its findings and status
 to the Audit Committee on a regular basis over the last
 year.&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Other new pronouncements issued but not effective until after
 September&amp;#xA0;30, 2017 are not expected to have a material impact
 on the Company&amp;#x2019;s consolidated financial statements.&lt;/p&gt;

 The Company generally offers a &lt;font style="WHITE-SPACE: nowrap"&gt;two-year&lt;/font&gt; warranty for all of its
 products, though it is party to a limited number of supply
 agreements with certain customers contractually committing the
 Company to warranty and indemnification requirements exceeding
 those to which the Company has been exposed in the past. Effective
 January&amp;#xA0;1, 2017, the Company extended the warranty period to
 three years for certain military grade products sold after that
 date. The Company provides for the estimated cost of product
 warranties at the time product revenue is recognized. Factors
 influencing the Company&amp;#x2019;s warranty reserves include the
 number of units sold, historical and anticipated rates of warranty
 returns, and the cost per return. The Company periodically assesses
 the adequacy of warranty reserves and adjusts the amounts as
 necessary. Warranty obligations are included in &amp;#x201C;Accrued
 expenses&amp;#x201D; in the accompanying Condensed Consolidated Balance
 Sheets.&lt;/p&gt;

 The Company has organized its business segments according to its
 key product lines. The Brick Business Unit segment
 (&amp;#x201C;BBU&amp;#x201D;) designs, develops, manufactures and markets the
 Company&amp;#x2019;s modular &lt;font style="WHITE-SPACE: nowrap"&gt;DC-DC&lt;/font&gt; converters and configurable
 products, and also includes the entities comprising Vicor Custom
 Power and the BBU operations of Vicor Japan Company, Ltd.
 (&amp;#x201C;VJCL&amp;#x201D;). The VI Chip segment includes VI Chip
 Corporation, which designs, develops, manufactures and markets many
 of the Company&amp;#x2019;s advanced power component products. The VI
 Chip segment also includes the VI Chip business conducted through
 VJCL. The Picor segment includes Picor Corporation, which designs,
 develops, manufactures and markets integrated circuits and related
 products for use in a variety of power management and power system
 applications. The Picor segment develops these products for use in
 the Company&amp;#x2019;s BBU and VI Chip modules, to be sold as
 complements to the Company&amp;#x2019;s BBU and VI Chip products, or for
 sale to third parties for separate (i.e., stand-alone)
 applications.&lt;/p&gt;

 The Company&amp;#x2019;s chief operating decision maker evaluates
 performance and allocates resources based on segment revenues and
 segment operating income (loss). The operating income (loss) for
 each segment includes selling, general and administrative and
 research and development expenses directly attributable to the
 segment. Certain of the Company&amp;#x2019;s indirect overhead costs,
 which include corporate selling, general and administrative
 expenses, are allocated among the segments based upon an estimate
 of costs associated with each segment. Assets allocated to each
 segment are based upon specific identification of such assets,
 which include accounts receivable, inventories, fixed assets and
 certain other assets. The Corporate segment consists of those
 operations and assets shared by all segments. The costs of certain
 centralized executive and administrative functions are recorded in
 this segment, as are certain shared assets, most notably cash and
 cash equivalents, deferred tax assets, long-term investments, the
 Company&amp;#x2019;s facilities in Massachusetts, real estate and other
 assets. The Company&amp;#x2019;s accounting policies and method of
 presentation for segments are consistent with that used throughout
 the Condensed Consolidated Financial Statements.&lt;/p&gt;

 As of September&#xA0;30, 2017 and December&#xA0;31, 2016, the
 Company held one 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 &#x201C;Failed Auction
 Security&#x201D;) since February 2008. 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.&#xA0;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 Security is presently at
 risk of default. Through September&#xA0;30, 2017, 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&#xA0;months. As a result, the Company continued
 to classify the Failed Auction Security as long-term as of
 September&#xA0;30, 2017.</p>

 Based on the fair value measurements described in Note&#xA0;3, the
 fair value of the Failed Auction Security on September&#xA0;30,
 2017, with a par value of $3,000,000, was estimated by the Company
 to be approximately $2,599,000. The gross unrealized loss of
 $401,000 on the Failed Auction Security consists of two types of
 estimated loss: an aggregate credit loss of $50,000 and an
 aggregate temporary impairment of $351,000. 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 (See Note&#xA0;3).</p>

 At this time, the Company has no intent to sell the impaired Failed
 Auction Security and does not believe it is more likely than not
 the Company will be required to sell this security. If current
 market conditions deteriorate further, the Company may be required
 to record additional unrealized losses. If the credit rating of the
 security deteriorates, the Company may be required to adjust the
 carrying value of the investment through impairment charges
 recorded in the Condensed Consolidated Statements of Operations,
 and any such impairment adjustments may be material.</p>

 Based on the Company&#x2019;s ability to access cash and cash

 not anticipate the current lack of liquidity associated with the

 The Company accounts for certain financial assets at fair value,
 defined as the price that would be received to sell an asset or
 paid to transfer a liability (i.e., an exit price) in the principal
 or most advantageous market for the asset or liability in an
 orderly transaction between market participants on the measurement
 date. As such, fair value is a market-based measurement that should
 be determined based on assumptions market participants would use in
 pricing an asset or liability. A three-level hierarchy is used to
 show the extent and level of judgment used to estimate fair value
 measurements.</p>

 As of September&#xA0;30, 2017, there was insufficient observable
 auction rate security market information available to determine the
 fair value of the Failed Auction Security using Level&#xA0;1 or
 Level&#xA0;2 inputs. As such, the Company&#x2019;s investment in the
 Failed Auction Security was deemed to require valuation using
 Level&#xA0;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 September&#xA0;30,
 2017. The major assumptions used in preparing the DCF model
 included: estimates for the amount and timing of future interest
 and principal payments based on default probability assumptions
 used to measure the credit loss of 2.0%; the rate of return
 required by investors to own this type of security in the current
 environment, which management estimates to be 5.0% above the risk
 free rate of return; and an estimated timeframe of three to five
 years for successful auctions for this type of security to occur.
 In making these assumptions, management considered relevant factors
 including: the formula applicable to the security defining the
 interest rate paid to investors in the event of a failed auction
 (the &#x201C;Penalty Rate&#x201D;); forward projections of the
 interest rate benchmarks specified in such formulas; the likely
 timing of principal repayments; the probability of full repayment
 considering the guarantees by the U.S.&#xA0;Department of Education
 of the underlying student loans, guarantees by other third parties,
 and additional credit enhancements provided through other means;
 and publicly available pricing data for recently issued student
 loan asset-backed securities not subject to auctions. In developing
 its estimate of the rate of return required by investors to own the
 security, management compared the Penalty Rate of the Failed
 Auction Security with yields of actively traded long-term bonds
 with similar characteristics and, reflecting the limited liquidity
 for auction rate securities and the discounts to par value seen in
 recent tender offers by issuers and arm&#x2019;s length market
 transactions between informed buyers and sellers, estimated the
 implied yield (i.e., the discount to par value) necessary to
 complete a sale of the Failed Auction Security. Management has
 calculated an increase or decrease in the liquidity risk premium of
 5.0% referenced above of 1.0% (i.e., 100&#xA0;basis points) as used
 in the model, would decrease or increase, respectively, the fair
 value of the Failed Auction Security by approximately $100,000.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The significant unobservable inputs used in the fair value
 measurement of the Failed Auction Security are the cumulative
 probability of earning the maximum rate until maturity, the
 cumulative probability of principal return prior to maturity, the
 cumulative probability of default, the liquidity risk premium, and
 the recovery rate in default.&#xA0;Significant increases
 (decreases) in any of those inputs in isolation would result in
 changes in fair value measurement. Significant increases
 (decreases) in the cumulative probability of earning the maximum
 rate until maturity, the cumulative probability of principal return
 prior to maturity, and the recovery rate in default would result in
 a higher (lower) fair value measurement, while increases
 (decreases) in the cumulative probability of default and the
 liquidity risk premium would result in a lower (higher) fair value
 measurement.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 Generally, the interrelationships are such that a change in the
 assumption used for the cumulative probability of principal return
 prior to maturity is accompanied by a directionally similar change
 in the assumption used for the cumulative probability of earning
 the maximum rate until maturity and a directionally opposite change
 in the assumptions used for the cumulative probability of default
 and the liquidity risk premium. The recovery rate in default is
 somewhat independent and based upon the security&#x2019;s specific
 underlying assets and published recovery rate indices.</p>

 The Company&#x2019;s Board of Directors approved the Vicor
 Corporation 2017 Employee Stock Purchase Plan (the
 &#x201C;Plan&#x201D; or the &#x201C;ESPP&#x201D;) on April&#xA0;26,
 2017. The ESPP became effective on June&#xA0;16, 2017, the date the
 Company&#x2019;s stockholders approved the Plan at the 2017 Annual
 Meeting of Stockholders. The Company has reserved 2,000,000 shares
 of Common Stock under the Plan for issuance to eligible employees
 who elect to participate. The ESPP is intended to qualify as an
 &#x201C;employee stock purchase plan&#x201D; under Section&#xA0;423
 of the Internal Revenue Code. The ESPP operates in successive
 periods of approximately six months, each referred to as an
 &#x201C;offering period.&#x201D; Generally, offering periods commence
 on or around September&#xA0;1 and March&#xA0;1 and end on or around
 the following February&#xA0;28 or August&#xA0;31, respectively.
 Under the ESPP, an option is granted to participating employees on
 the first day of an offering period to purchase shares of the
 Company&#x2019;s Common Stock at the end of that offering period at
 a purchase price equal to 85% of the lesser of the fair market
 value of a share of Common Stock on either the first day or the
 last day of that offering period. The purchase of shares is funded
 by means of periodic payroll deductions, which may not exceed 15.0%
 of the employee&#x2019;s eligible compensation, as defined in the
 Plan. Among other provisions, the Plan limits the number of shares
 that can be purchased by a participant during any offering period
 and cumulatively for any calendar year.</p>

 On December&#xA0;31, 2010, the Company granted
 2,984,250&#xA0;<font style="WHITE-SPACE: nowrap">non-qualified</font>&#xA0;stock
 options under the VI Chip 2007 Stock Option and Incentive Plan with
 performance-based vesting provisions tied to achievement of certain
 margin targets by VI Chip Corporation. As of December&#xA0;31,
 2010, the Company determined it was probable the margin targets
 could be achieved and, accordingly, began recording stock-based
 compensation expense relating to these options beginning
 January&#xA0;1, 2011. During the third quarter of 2016, the Company
 determined the margin targets would not be met prior to the
 expiration date of the corresponding options, as VI Chip&#x2019;s
 revenue growth has been below levels necessary to achieve the
 targets. As a result, in accordance with the accounting guidance
 for performance-based stock options, the Company reversed
 approximately $768,000 of previously recorded stock-based
 compensation expense in the third quarter of 2016, representing all
 expense taken for these performance-based options through
 June&#xA0;30, 2016. This resulted in decreases in cost of revenues
 of $86,000, selling, general and administrative expense of
 $516,000, and research and development expense of $166,000 for the
 three and nine months ended September&#xA0;30, 2016.</p>

 Inventories are valued at the lower of cost (determined using the
 <font style="white-space:nowrap">first-in,</font> <font style="white-space:nowrap">first-out</font> method) or net realizable
 value. Fixed production overhead is allocated to the inventory cost
 per unit based on the normal capacity of the production facilities.
 Abnormal production costs, including fixed cost variances from
 normal production capacity, if any, are charged to cost of revenues
 in the period incurred. All shipping and handling costs incurred in
 connection with the sale of products are included in cost of
 revenues.</p>
 <p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 The Company provides reserves for inventories estimated to be
 excess, obsolete or unmarketable. The Company&#x2019;s estimation
 process for assessing net realizable value is based upon its known
 backlog, projected future demand, historical consumption and
 expected market conditions. 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.</p>

 The Company generally offers a <font style="WHITE-SPACE: nowrap">two-year</font> warranty for all of its
 products, though it is party to a limited number of supply
 agreements with certain customers contractually committing the
 Company to warranty and indemnification requirements exceeding
 those to which the Company has been exposed in the past. Effective
 January&#xA0;1, 2017, the Company extended the warranty period to
 three years for certain military grade products sold after that
 date. The Company provides for the estimated cost of product
 warranties at the time product revenue is recognized. Factors
 influencing the Company&#x2019;s warranty reserves include the
 number of units sold, historical and anticipated rates of warranty
 returns, and the cost per return. The Company periodically assesses
 the adequacy of warranty reserves and adjusts the amounts as
 necessary. Warranty obligations are included in &#x201C;Accrued
 expenses&#x201D; in the accompanying Condensed Consolidated Balance
 Sheets.</p>

 $55,000 was reversed and recorded as a discrete benefit in the
 first quarter of 2016.</p>
 <p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 As described in Note <font style="white-space:nowrap">11-</font>
 Impact of Recently Issued Accounting Standards, the Company adopted
 new guidance for employee share-based payment accounting during the
 first quarter of 2017. The new guidance, among other
 considerations, requires excess tax benefits and tax deficiencies
 related to employee share-based compensation to now be recorded in
 earnings when the awards vest or are settled, rather than in
 shareholders&#x2019; equity under previous guidance. In addition, it
 eliminates the requirement that excess tax benefits be realized
 with the taxing authority before they can be recognized. In
 connection with the adoption of this new guidance, the Company
 recorded a cumulative-effect adjustment as of January&#xA0;1, 2017
 to increase gross deferred tax assets and the related valuation
 allowance against deferred tax assets by $3,485,000. This amount
 was allocated and added to deferred tax assets for research and
 development tax credit carryforwards, net operating loss
 carryforwards and the alternative minimum tax credit carryforward
 but, as noted above, was fully offset by a corresponding increase
 in the valuation allowance against deferred tax assets, resulting
 in no net effect on the Company&#x2019;s condensed consolidated
 financial statements.</p>
 <p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 As of September&#xA0;30, 2017, the Company continues to maintain a
 valuation allowance of approximately $32,746,000 against all
 domestic net deferred tax assets and the majority of foreign net
 deferred tax assets, for which realization cannot be considered
 more likely than not at this time.</p>
 <p style="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 In May 2017, the Company received notice from the Internal Revenue
 Service that its federal corporate tax return for tax year 2015 had
 been selected for examination. The examination is ongoing.</p>

 At September&#xA0;30, 2017, the Company had approximately
 $3,006,000 of capital expenditure commitments.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">
 On January&#xA0;28, 2011, SynQor, Inc. (&#x201C;SynQor&#x201D;) filed
 a complaint for patent infringement against Ericsson, Inc.
 (&#x201C;Ericsson&#x201D;), Cisco Systems, Inc. (&#x201C;Cisco&#x201D;)
 and the Company in the U.S. District Court for the Eastern District
 of Texas (the &#x201C;Texas Action&#x201D;). Ericsson and Cisco
 subsequently settled with SynQor and are no longer parties to the
 Texas Action. With respect to the Company, SynQor&#x2019;s complaint
 in the Texas Action alleged 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, and
 7,564,702 (&#x201C;the &#x2018;190 patent&#x201D;, &#x201C;the
 &#x2018;021 patent&#x201D; and &#x201C;the &#x2018;702 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. On September&#xA0;20, 2011, SynQor filed an amended complaint
 in the Texas Action that further alleged 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 number 8,023,290 (&#x201C;the
 &#x2018;290 patent&#x201D;). The Company responded to SynQor&#x2019;s
 amended complaint in the Texas Action by denying its products
 infringe any of the SynQor patents, and asserting that the SynQor
 patents are invalid. The Company further alleged that the SynQor
 &#x2018;290 patent is unenforceable due to inequitable conduct by
 SynQor or its agents during the examination of the &#x2018;290
 patent at the United States Patent and Trademark Office
 (&#x201C;USPTO&#x201D;). The Company also asserted counterclaims
 seeking damages against 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.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">
 The Company initiated administrative review proceedings at the
 USPTO challenging the validity of certain claims of the SynQor
 patents asserted in the Texas Action, including all claims that
 were asserted against the Company by SynQor. Regarding the
 &#x2018;190 patent, the Patent Trial and Appeal Board
 (&#x201C;PTAB&#x201D;) of the USPTO issued a decision upholding the
 validity of the &#x2018;190 patent claims. That decision was
 appealed by the Company to the United States Court of Appeals for
 the Federal Circuit (&#x201C;the Federal Circuit&#x201D;), which
 issued a decision on March&#xA0;13, 2015 reversing the PTAB,
 determining that certain claims were invalid, and remanding the
 matter to the PTAB for further proceedings. On May&#xA0;2, 2016,
 the PTAB issued a decision determining that all but one of the
 remaining claims of the &#x2018;190 patent were invalid and
 remanding the remaining claim to a patent examiner for further
 examination. On June&#xA0;22, 2017, the examiner issued a
 determination under 37 C.F.R. &#xA7; 41.77(d), finding that the
 remaining claim of the &#x2018;190 patent was unpatentable. That
 decision is expected to be further reviewed by the PTAB pursuant to
 37 C.F.R. &#xA7; 41.77(f).</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">
 On May&#xA0;2, 2016, the PTAB also issued decisions finding all
 challenged claims of SynQor&#x2019;s &#x2018;021 patent invalid and
 upholding the validity of all challenged claims of SynQor&#x2019;s
 &#x2018;702 and &#x2018;290 patents. On May&#xA0;23, 2016, the Texas
 Court issued an order staying the Texas Action until the completion
 of all of the administrative review proceedings concerning the
 asserted SynQor patents, including any appeals from such
 proceedings to the Federal Circuit.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">
 On August&#xA0;30, 2017, the Federal Circuit issued rulings with
 regard to PTAB&#x2019;s reexamination decisions for the &#x2018;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. 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.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">
 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, 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.</p>
 <p style="font-size:1px;margin-top:6px;margin-bottom:0px">
 &#xA0;</p>
 <p style="margin-top:0pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">
 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.</p>

 Corporation, which designs, develops, manufactures and markets many
 of the Company&#x2019;s advanced power component products. The VI
 Chip segment also includes the VI Chip business conducted through
 VJCL. The Picor segment includes Picor Corporation, which designs,
 develops, manufactures and markets integrated circuits and related
 products for use in a variety of power management and power system
 applications. The Picor segment develops these products for use in
 the Company&#x2019;s BBU and VI Chip modules, to be sold as
 complements to the Company&#x2019;s BBU and VI Chip products, or for
 sale to third parties for separate (i.e., stand-alone)

 The Company&#x2019;s chief operating decision maker evaluates
 performance and allocates resources based on segment revenues and
 segment operating income (loss). The operating income (loss) for
 each segment includes selling, general and administrative and
 research and development expenses directly attributable to the
 segment. Certain of the Company&#x2019;s indirect overhead costs,
 which include corporate selling, general and administrative
 expenses, are allocated among the segments based upon an estimate
 of costs associated with each segment. Assets allocated to each
 segment are based upon specific identification of such assets,
 which include accounts receivable, inventories, fixed assets and
 certain other assets. The Corporate segment consists of those
 operations and assets shared by all segments. The costs of certain
 centralized executive and administrative functions are recorded in
 this segment, as are certain shared assets, most notably cash and
 cash equivalents, deferred tax assets, long-term investments, the
 Company&#x2019;s facilities in Massachusetts, real estate and other
 assets. The Company&#x2019;s accounting policies and method of
 presentation for segments are consistent with that used throughout
 the Condensed Consolidated Financial Statements.</p>

 In May 2017, the Financial Accounting Standards Board
 (&#x201C;FASB&#x201D;) issued guidance about which changes to the
 terms or conditions of a share-based payment award require an
 entity to apply modification accounting in Topic 718,
 <i>Compensation &#x2013; Stock Compensation</i>. The new guidance is
 effective for annual and interim periods beginning after
 December&#xA0;15, 2017, with early adoption permitted. The Company
 does not expect the adoption of the new guidance will have a
 material impact on its consolidated financial statements and
 related disclosures.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 In August 2016, the FASB issued guidance to clarify how certain
 cash receipts and cash payments should be presented in the
 statement of cash flows. These include debt prepayment, settlement
 of <font style="WHITE-SPACE: nowrap">zero-coupon</font> debt
 instruments, contingent consideration payments made after a
 business combination, proceeds from the settlement of insurance
 claims, proceeds from the settlement of corporate-owned life
 insurance policies, distributions received from equity method
 investees and beneficial interests in securitization transactions.
 The new guidance is effective for interim and annual reporting
 periods beginning after December&#xA0;15, 2017, with early adoption
 permitted. The Company does not expect the adoption of the new
 guidance will have a material impact on its consolidated financial
 statements and related disclosures.</p>

 In June 2016, the FASB issued new guidance which will require
 measurement and recognition of expected credit losses on certain
 types of financial instruments. It also modifies the impairment
 model for <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">available-for-sale</font></font> debt
 securities and provides for a simplified accounting model for
 purchased financial assets with credit deterioration since their
 origination. The new guidance is effective for interim and annual
 reporting periods beginning after December&#xA0;15, 2019, with
 early adoption permitted. It is required to be applied on a
 modified-retrospective approach with certain elements being adopted
 prospectively. The Company has not yet determined the impact this
 new guidance will have on its consolidated financial statements and
 related disclosures.</p>

 In March 2016, the FASB issued new guidance for employee
 share-based payment accounting, which makes several modifications
 to existing guidance related to the accounting for forfeitures,
 employer tax withholding on share-based compensation and the
 financial statement presentation of excess tax benefits or
 deficiencies. This new guidance also clarifies the statement of
 cash flows presentation for certain components of share-based
 awards. In terms of the accounting for forfeitures, the new
 guidance allows an option for them to either be estimated, as
 currently required, or recognized when they occur. The Company will
 continue to estimate forfeitures. The Company adopted the new
 standard on January&#xA0;1, 2017. (See Note 8 &#x2013; Income Taxes
 for additional details on the impact of the adoption).</p>

 In February 2016, the FASB issued new guidance for lease
 accounting, which will require lessees to recognize leases on the
 balance sheet and disclose key information about leasing
 arrangements. The new guidance establishes a <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">right-of-use</font></font> model
 (&#x201C;ROU&#x201D;) that will require a lessee to recognize a ROU
 asset and a lease liability on the balance sheet for all leases
 with a term longer than twelve months. Leases will be classified as
 finance or operating, with classification affecting the pattern and
 classification of expense recognition in the income statement. For
 lessors, the guidance modifies the classification criteria and
 accounting for sales-type and direct financing leases. The new
 standard is effective for interim and annual periods beginning
 after December&#xA0;15, 2018, with early adoption permitted. The
 Company plans to adopt the new guidance effective January&#xA0;1,
 2019. The new standard must be adopted using a modified
 retrospective transition which includes certain practical
 expedients. The majority of the Company&#x2019;s leases are for
 certain of its office and manufacturing space. The Company has not
 yet determined the impact this new guidance will have on its
 consolidated financial statements and related disclosures.</p>

 In May 2014, the FASB issued new guidance for revenue recognition,
 which will require an entity to recognize the amount of revenue to
 which it expects to be entitled for the transfer of promised goods
 or services to customers. The new guidance, which includes several
 amendments, will replace most existing revenue recognition guidance
 in U.S. Generally Accepted Accounting Principles when it becomes
 effective, which will be January&#xA0;1, 2018 for the Company. The
 new standard permits the use of either the retrospective or
 cumulative effect transition method. The Company has established an
 implementation team to assess the potential impact of the new
 standard which includes identifying appropriate changes to the
 business processes, systems and controls to support revenue
 recognition and disclosure requirements under the new standard.
 While the implementation team is still in the process of completing
 its evaluation of the new standard, it has reached preliminary
 conclusions on substantially all key accounting assessments, and
 currently believes the most significant impact will be related to
 the timing of recognition of sales to its stocking distributors.
 The Company currently defers revenue and the related cost of sales
 on shipments to stocking distributors until the distributors resell
 the products to their customers. Upon adoption of the new guidance,
 the Company will no longer be permitted to defer revenue until sale
 by the stocking distributor to the end customer, but rather, will
 be required to estimate the effects of returns and allowances
 provided to stocking distributors and record revenue at the time of
 sale to the stocking distributor. The Company currently plans to
 utilize the retrospective transition method for adoption of the
 standard. Upon adoption under that method, the Company will
 recognize the cumulative effect of adopting this guidance as an
 adjustment to the balance of retained earnings as of
 January&#xA0;1, 2016. The implementation team is continuing to
 evaluate the method of adoption and the future impact the new
 guidance will have on its consolidated financial statements and
 related disclosures and expects to complete its assessment of those
 financial statement impacts during the fourth quarter of 2017. The
 other principal remaining implementation items include completing
 the identification and documentation of key transition controls
 and, later, the identification and documentation of any new or
 revised key ongoing process controls. The implementation team
 expects to complete those tasks by the end of the fourth quarter of
 2017. The implementation team has reported its findings and status
 to the Audit Committee on a regular basis over the last
 year.&#xA0;&#xA0;&#xA0;&#xA0;</p>

 Other new pronouncements issued but not effective until after
 September&#xA0;30, 2017 are not expected to have a material impact
 on the Company&#x2019;s consolidated financial statements.</p>

 business processes, systems and controls to support revenue
 recognition and disclosure requirements under the new standard.
 While the implementation team is still in the process of completing
 its evaluation of the new standard, it has reached preliminary
 conclusions on substantially all key accounting assessments, and
 currently believes the most significant impact will be related to
 the timing of recognition of sales to its stocking distributors.
 The Company currently defers revenue and the related cost of sales
 on shipments to stocking distributors until the distributors resell
 the products to their customers. Upon adoption of the new guidance,
 the Company will no longer be permitted to defer revenue until sale
 by the stocking distributor to the end customer, but rather, will
 be required to estimate the effects of returns and allowances
 provided to stocking distributors and record revenue at the time of
 sale to the stocking distributor. The Company currently plans to
 utilize the retrospective transition method for adoption of the
 standard. Upon adoption under that method, the Company will
 recognize the cumulative effect of adopting this guidance as an
 adjustment to the balance of retained earnings as of
 January&#xA0;1, 2016. The implementation team is continuing to
 evaluate the method of adoption and the future impact the new
 guidance will have on its consolidated financial statements and
 related disclosures and expects to complete its assessment of those
 financial statement impacts during the fourth quarter of 2017. The
 other principal remaining implementation items include completing
 the identification and documentation of key transition controls
 and, later, the identification and documentation of any new or
 revised key ongoing process controls. The implementation team
 expects to complete those tasks by the end of the fourth quarter of
 2017. The implementation team has reported its findings and status
 to the Audit Committee on a regular basis over the last
 year.&#xA0;&#xA0;&#xA0;&#xA0;</p>
