<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 Financial Accounting Standards Board (&#147;FASB&#148;) issued new guidance for revenue recognition
(&#147;Topic 606&#148;), which requires 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, replaces most
of the prior revenue recognition guidance under U.S. Generally Accepted Accounting Principles. The Company adopted the new guidance as of January&nbsp;1, 2018 using the modified retrospective method, as applied to all contracts. As a result, the
Company has changed its accounting policy for revenue recognition, as detailed below. The most significant impact of the adoption was on the timing of recognition of sales to the Company&#146;s stocking distributors and including the additional
required disclosures under the new standard. Through December&nbsp;31, 2017, the Company deferred revenue and the related cost of sales on shipments to stocking distributors until the distributors resold the products to their customers. Upon
adoption, the Company is no longer permitted to defer revenue until sale by the stocking distributor to the end customer, but rather, is 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. In addition, the Company modified the accounting for a contractual arrangement due to a reassessment of the number of performance obligations in the arrangement, and adjusted for the timing of certain
royalty revenue. The cumulative effect of adopting this guidance, recorded as an increase to the balance of retained earnings as of January&nbsp;1, 2018, was approximately $3,670,000. The comparative information for the three and six months ended
December&nbsp;31, 2017, including disclosures, has not been restated and continues to be reported under the accounting standards in effect for that period. </P>

the Company deferred revenue and the related cost of sales on shipments to stocking distributors until the stocking distributors resold the products to their customers. Accordingly, the
Company&#146;s revenue fully reflected <FONT STYLE="white-space:nowrap">end-customer</FONT> purchases and was not impacted by stocking distributor inventory levels. Agreements with stocking distributors limited returns of qualifying product to the
Company to a certain percentage of the value of the Company&#146;s shipments to that stocking distributor during the prior quarter. In addition, stocking distributors were allowed to return unsold products if the Company terminated the relationship
with the stocking distributor. Title to the inventory transferred to the stocking distributor at the time of shipment or delivery to the stocking distributor. Payment from the stocking distributors were due in accordance with the Company&#146;s
standard payment terms. These payment terms were not contingent upon the stocking distributors&#146; sale of the products to their <FONT STYLE="white-space:nowrap">end-customers.</FONT> Upon title transfer to stocking distributors, the Company
reduced inventory for the cost of goods shipped, the margin (i.e., revenues less cost of revenues) was recorded as deferred revenue, and an account receivable was recorded. As of December&nbsp;31, 2017, the Company had gross deferred revenue of
approximately $4,659,000 and gross deferred cost of revenues of approximately $2,135,000 under agreements with stocking distributors. </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 evaluated revenue arrangements with potential multi-element deliverables to determine if there were more than one
unit of accounting. A deliverable constituted a separate unit of accounting when it had standalone value and there were no customer-negotiated refund or return rights for the undelivered elements. The Company entered into arrangements containing
multiple elements that could include a combination of <FONT STYLE="white-space:nowrap">non-recurring</FONT> engineering services (&#147;NRE&#148;), prototype units, and production units. The Company determined NRE and prototype units represented one
unit of accounting and production units represented a separate unit of accounting, based on an assessment of the respective standalone value. The Company deferred revenue recognition for NRE and prototype units until completion of the final
milestone under the NRE arrangement, which was generally the delivery of the prototype. Recognition generally took place within six to twelve months of the initiation of the arrangement. Revenue for the production units was recognized upon shipment,

revenue on such arrangements only when the contract was signed, the license term had begun, all obligations had been delivered to the customer, and collection was probable. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">Revenue is recognized when control of the promised goods or services is transferred to a customer, in an amount that reflects
the consideration the Company expects to be entitled to in exchange for those goods or services. Sales, value add, and other taxes collected concurrent with revenue-producing activities are excluded from revenue. The expected costs associated with
product warranties continue to be recognized at the time product revenue is recognized. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost
and 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&#146;s primary source of net revenue comes from the sale of products,
which are modular power components and power systems for converting, regulating and controlling electric current. The principal customers for the Company&#146;s power converters and systems are large original equipment manufacturers and the original
design manufacturers and contract manufacturers serving them, and smaller, lower volume users, which are broadly distributed across several major market areas. The Company recognizes revenue for product sales at a point in time following the
transfer of control of such products to the customer, which typically occurs upon shipment or delivery, depending on the terms of the underlying contract. As noted above, the Company previously deferred revenue and the related cost of revenues on
shipments to stocking distributors until the distributors resold the products to their customers. The Company now records revenue for such transactions at the time of sale to the stocking distributor. The Company establishes sales allowances for
estimated future product returns including distributor returns and price adjustment credits,&nbsp;primarily based upon historical and anticipated rates of product returns and allowances. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">Certain contracts with customers contain multiple performance obligations, which typically may include a combination of NRE,
prototype units, and production units. For these contracts, the individual performance obligations are accounted for separately if they are distinct. Generally, the Company has determined the NRE and prototype units represent one distinct
performance obligation and the production units represent a separate distinct performance obligation. For such arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price, based on prices charged
to customers or using the expected cost plus a margin approach. The Company defers revenue recognition for NRE and prototype </P>

upon a percentage of the licensee&#146;s sales. The Company utilizes the exception under the revenue recognition guidance for the recognition of sales- or usage-based royalties, in which the royalties are not recognized until the later of when 1)
the customer&#146;s subsequent sales or usages occur, or 2) the performance obligation to which some or all of the sales- or usage-based royalty has been allocated is satisfied or partially satisfied. </P>

realizable value. The Company&#146;s payment terms vary by the type and location of its customers and the products or services offered, although terms generally include a requirement of payment within 30 to 60 days. The Company maintains allowances
for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, based on assessments of customers&#146; credit-risk profiles and payment histories. If the financial condition of the Company&#146;s
customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company does not require collateral from its customers, although there have been circumstances when the Company
has required cash in advance (i.e., a partial down-payment) to facilitate orders in excess of a customer&#146;s established credit limit. To date, such amounts have not been material. </P>

of performance under a contract with a customer. During the three and six months ended June&nbsp;30, 2018, under Topic 606, the Company recognized revenue of approximately $340,000 and $385,000, respectively, that was included in deferred revenue at
the beginning of each respective period. </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 applies the practical expedient allowed under the new guidance for

 <P STYLE="margin-top:0pt; margin-bottom:0pt; margin-left:8%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The increase in accounts receivable was primarily due to an increase in net
revenues of approximately $15,425,000 in the second quarter of 2018 compared to the fourth quarter of 2017. The decrease in deferred revenue was primarily due to the adoption of the new revenue recognition guidance, as the balances related to
stocking distributors were reversed as part of the transition adjustment recorded as of January&nbsp;1, 2018 (see Note 2 to the Condensed Consolidated Financial Statements). The increase in deferred expenses is primarily due to additional work
incurred on certain NRE projects during the second quarter of 2018 for which the associated revenue is being deferred. The increase in sales allowances was due to the establishment of new allowances, in connection with the new revenue recognition
guidance, for potential returns and price adjustment credits on sales to stocking distributors. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:8%; text-indent:4%; font-size:10pt; font-family:Times New Roman">Deferred expenses are
included in Other current assets, and customer prepayments are included in Deferred revenue, in the accompanying Condensed Consolidated Balance Sheets, respectively. </P>

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 June&nbsp;30, 2018, 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 June&nbsp;30, 2018. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:8%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The following is a summary of <FONT STYLE="white-space:nowrap"><FONT

Auction Security on June&nbsp;30, 2018, with a par value of $3,000,000, was estimated by the Company to be approximately $2,581,000. The gross unrealized loss of $419,000 on the Failed Auction Security consists of two types of estimated loss: an
aggregate credit loss of $44,000 and an aggregate temporary impairment of $375,000. 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&nbsp;5). </P>

information available to determine the fair value of the Failed Auction Security using Level&nbsp;1 or Level&nbsp;2 inputs. As such, the Company&#146;s investment in the Failed Auction Security was deemed to require valuation using Level&nbsp;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&#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 June&nbsp;30,
2018. The major assumptions used in preparing the DCF model were similar to those described in Note 5 - Fair Value Measurements in the Notes to the Consolidated Financial Statements contained in the Company&#146;s 2017 Form <FONT

</TABLE> <P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">The effective tax rate was lower than the statutory tax rate in 2018 due to the utilization of
net operating carryforwards and tax credits. The provisions for income taxes in each 2017 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 these periods due to a full valuation allowance against all net domestic deferred tax assets. The provision and effective income tax rate
were higher in the second quarter of 2017 as the Company had previously recorded a tax benefit in the first quarter of 2017. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">On December&nbsp;22, 2017, the U.S. government enacted comprehensive tax legislation, referred to as the Tax Cuts and Jobs Act
(the &#147;Tax Act&#148;). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to: (1)&nbsp;reducing the U.S. federal corporate tax rate from 35% to 21%; (2) elimination of the corporate alternative minimum
tax (&#147;AMT&#148;) and changing how existing AMT credits can be realized; (3)&nbsp;changing rules related to the usage and limitation of net operating loss carryforwards created in tax years beginning after December&nbsp;31, 2017; and
(4)&nbsp;implementing a territorial tax system, which generally eliminates the U.S. federal income tax on dividends from foreign subsidiaries, and imposes <FONT STYLE="white-space:nowrap">a&nbsp;one-time&nbsp;transition</FONT> tax on certain
earnings of foreign subsidiaries previously untaxed in the United States. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">Certain impacts of the Tax Act would generally
require accounting to be completed in the period of enactment. However, in response to the complexities of the Tax Act, the Securities and Exchange Commission (&#147;SEC&#148;) issued guidance through Staff Accounting Bulletin No.&nbsp;118 to
provide companies with relief. Specifically, when the initial accounting for items under the Tax Act is incomplete, the guidance allows companies to include provisional amounts when reasonable estimates can be made. The SEC has provided up to <FONT
STYLE="white-space:nowrap">a&nbsp;one-year&nbsp;measurement</FONT> period for companies to finalize the accounting for the impact of the new legislation and the Company expects to finalize the accounting over the coming quarters. The Company has
recognized the provisional tax impacts related to <FONT STYLE="white-space:nowrap">the&nbsp;re-measurement&nbsp;of</FONT> its deferred tax assets and liabilities, <FONT STYLE="white-space:nowrap">and&nbsp;one-time&nbsp;transition</FONT> tax, for the
year ended December&nbsp;31, 2017. The ultimate impact may differ from these provisional amounts due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that
may be issued, and actions the Company may take as a result of the Tax Act. There were no changes to the provisional tax impacts referred to above in the first or second quarters of 2018. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">As of June&nbsp;30, 2018, the Company continues to maintain a valuation
allowance of approximately $33,024,000 against all domestic net deferred tax assets. Management assesses the need for the valuation allowance on a quarterly basis. In assessing the need for a valuation allowance, the Company considers all positive
and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and past financial performance. Due to improving financial results, there is increasing positive evidence to
support realization of deferred tax assets. Until actual operating results continue to be consistently positive, and the Company believes it is more likely than not it can forecast sufficient future taxable income of the appropriate nature to
realize those deferred tax assets, it will continue to maintain the full valuation allowance position. If and when the Company determines the valuation allowance should be released (i.e., reduced), the adjustment would result in a tax benefit
reported in that period&#146;s consolidated statements of operations, the effect of which would be an increase in reported net income. </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 was completed in May 2018 resulting in no tax liability to the Company. In January 2018, the Company received notice from the New York State Department of Taxation that its New York State tax
returns for tax years 2014 through 2016 were selected for audit. Onsite fieldwork for this audit was completed in May 2018, and the Company is awaiting the results of the audit. </P>

June&nbsp;30, 2018, the Company had approximately $2,044,000 of capital expenditure commitments. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company is the defendant in a patent
infringement lawsuit originally filed on January&nbsp;28, 2011 by SynQor, Inc. (&#147;SynQor&#148;) in the U.S. District Court for the Eastern District of Texas (the &#147;Texas Action&#148;). The complaint, as amended in September 2011, alleges
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, 7,564,702, and 8,023,290
(&#147;the &#145;190 patent&#148;, &#147;the &#145;021 patent&#148;, &#147;the &#145;702 patent&#148;, and &#147;the &#145;290 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.&nbsp;The Company has denied that its products infringe any of the SynQor patents, asserted that the SynQor patents are invalid, and asserted that the &#145;290 patent
is unenforceable due to inequitable conduct by SynQor or its agents during the examination of the &#145;290 patent&nbsp;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. On May&nbsp;23, 2016, after extensive discovery, the
Texas Action was stayed by the court pending completion of certain inter partes reexamination proceedings at the USPTO (including any appeals from such proceedings to the Federal Circuit (as defined below)) concerning the SynQor patents, which are
described below. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In response to the Texas Action, the Company initiated inter partes reexamination 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. The current status of these proceedings is as follows. Regarding the &#145;190 patent, the
United States Court of Appeals for the Federal Circuit (the &#147;Federal Circuit&#148;) issued a decision on March&nbsp;13, 2015, determining that certain claims were invalid, and remanding the matter to the Patent Trial and Appeal Board
(&#147;PTAB&#148;) of the USPTO 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). 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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; 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:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On October&nbsp;31, 2017, the Company filed a request with the USPTO for ex parte
reexamination of the &#145;702 patent, based on different prior art references than had been at issue in the previous inter parte reexamination of the &#145;702 patent. On December&nbsp;6, 2017, the USPTO issued a decision granting the
Company&#146;s request and initiating ex parte reexamination of the &#145;702 patent. On March&nbsp;21, 2018, the USPTO issued a <FONT STYLE="white-space:nowrap">non-final</FONT> office action finding all of the challenged claims of the &#145;702
patent to be unpatentable. On May&nbsp;14, 2018, SynQor filed a petition asking the USPTO to vacate its prior decision granting the Company&#146;s request for ex parte reexamination. No action has been taken on the petition to date. The Company
continues to monitor the progress of this proceeding. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; 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> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; 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&#146;s
financial position or results of operations. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">13. <U>Picor Merger</U> </P>

Corporation (&#147;Picor&#148;), a subsidiary of Vicor, fully consolidated for financial reporting purposes, in which the Company was the majority stockholder. The merger was completed as of May&nbsp;30, 2018, at which time the separate corporate
existence of Picor ceased. To effect the merger, holders of Picor Common Stock and Picor stock options received an equivalent value of Vicor Common Stock and Vicor stock options, respectively, which caused the Picor Corporation Amended and Restated
2001 Stock Option and Incentive Plan, and options outstanding thereunder, to be assumed and restated by Vicor. While Picor&#146;s subsidiary status and corporate form ceased to exist upon the closing of the merger, the operations previously
conducted by Picor, which are now legally merged into Vicor, continue to be managed and remain categorized as a segment for financial reporting purposes. There was no net impact on the Company&#146;s consolidated financial statements nor any impact
on the Company&#146;s segment reporting for the three and six months ended June&nbsp;30, 2018 as a result of the merger. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">14. <U>Segment Information</U>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In June 2018, the FASB issued new guidance<I>, Improvements to Nonemployee Share-Based Payment Accounting</I> , which more
closely aligns the accounting for share-based payments to <FONT STYLE="white-space:nowrap">non-employees</FONT> with the accounting for share-based payments to employees. This new guidance is effective for public business entities for annual and
interim periods in fiscal years beginning after December&nbsp;15, 2018. Early adoption is permitted, but no earlier than an entity&#146;s adoption date of Topic 606.The Company is currently evaluating the impact this new guidance will have on its
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 FASB 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 adopted the new standard on January&nbsp;1, 2018. The adoption of this new guidance did not 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 adopted the new standard on January&nbsp;1, 2018. The adoption of this new guidance did not 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 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 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 majority of the Company&#146;s leases are
for certain of its office and manufacturing space. The Company has developed an implementation plan and continues to gather information, including compiling an inventory of all leasing arrangements, to assess the impact of the new standard on its
financial statements. 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 Company has not yet determined the impact this new guidance will have on its consolidated financial statements and related disclosures. </P>

historical fact contained herein, statements in this report constitute forward-looking statements within the meaning of Section&nbsp;27A of the Securities Act of 1933, as amended, and Section&nbsp;21E of the Securities Exchange Act of 1934, as
amended. The words &#147;believes,&#148; &#147;expects,&#148; &#147;anticipates,&#148; &#147;intends,&#148; &#147;estimates,&#148; &#147;plans,&#148; &#147;assumes,&#148; &#147;may,&#148; &#147;will,&#148; &#147;would,&#148; &#147;should,&#148;
&#147;continue,&#148; &#147;prospective,&#148; &#147;project,&#148; and other similar words or expressions 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 on Form <FONT STYLE="white-space:nowrap">10-K</FONT> for the year ended December&nbsp;31, 2017, under Part I, Item&nbsp;1 &#151;

our legacy lines of <FONT STYLE="white-space:nowrap">DC-DC</FONT> converters and configurable products, as well as complementary components providing AC line rectification, input filtering, power factor correction, and transient protection. The BBU
segment also includes the BBU business conducted through Vicor Japan Company, Ltd. (&#147;VJCL&#148;) and our Vicor Custom Power subsidiaries. The BBU has customers concentrated in aerospace and aviation, defense electronics, industrial automation,
industrial 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 the 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, autonomous driving, defense electronics, electric and hybrid vehicles,
instrumentation and test equipment, networking equipment, and solid state lighting. </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 the operations of our
former subsidiary, Picor Corporation, which was merged into Vicor in May 2018 (see Note 13 to the Condensed Consolidated Financial Statements). The Picor segment designs, develops, and markets integrated circuits for use in a variety of power
management and power system applications. The Picor segment is a &#147;fabless manufacturer,&#148; as its products are manufactured, assembled, packaged, and tested by third parties in Asia and the United States. The Picor segment 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, and are often integrated with VI Chip products to
enable a customer solution, particularly in the datacenter and supercomputer segments of the computing market. While Picor Corporation&#146;s subsidiary status and corporate form ceased to exist upon the closing of the merger, the operations
previously legally merged into Picor Corporation, which are now conducted by Vicor, continue to be managed and remain categorized as a segment for financial reporting purposes. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our improved consolidated operating results for the second quarter of 2018 were driven by an increase in net revenues, a consequence of
sequential quarterly increases in bookings and order backlog, as well as improved gross margins resulting from higher production volumes, favorable product mix, and improved pricing. The sequential increase in quarterly revenue for the period was
primarily a result of double-digit percentage increases in the value of shipments of certain legacy and advanced product lines, as well as the start of production shipments of our

of our 48 volt to <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">point-of-load</FONT></FONT> solutions for datacenters and supercomputers accelerated during the second quarter of 2018, with increased order volumes for our <FONT

legacy brick converters, configurable products, and associated components have recovered and are above historical trend, which we attribute primarily to the extended recovery of economic conditions in the geographies and markets we serve, notably in
defense electronics, high-value capital goods, and rail. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We believe the following considerations may influence our performance over the

<TD ALIGN="left" VALIGN="top">We operate a highly automated electronics manufacturing facility in Andover, Massachusetts, and our profitability is closely aligned with production unit volumes. We have invested significantly in <FONT
STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">state-of-the-art</FONT></FONT></FONT> systems, equipment, and robotics, which allow us to generate relatively higher profitability when operating at or near
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>

<TD ALIGN="left" VALIGN="top">Our ability to achieve sustained, high volume production levels is tied to our ability to forecast manufacturing requirements of a range of inputs, notably raw material inventories. Because we utilize a number of
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, which often cause prices of these
components and materials to rise. To mitigate supply chain risks, we focus on identifying and reducing potential vulnerabilities to stock-outs, vendor shortages, and similar disruptions. We maintain safety-stock programs for certain critical
components and materials, and these programs recently have contributed to increased levels of raw material inventory. We also have established second-source supply relationships, in order to reduce exposure to material shortages. However, the global
electronics supply chain continues to experience lengthened lead times, and our product-level profitability and overall performance could be negatively influenced by an unplanned shortage of a particular component or material. We do not expect
lead-times to shorten in 2018 and anticipate availability of certain commodity components will remain uncertain. </TD></TR></TABLE> <P STYLE="font-size:6pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

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 June&nbsp;30, 2018, 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 June&nbsp;30, 2018. </P>
<P STYLE="margin-top:12pt; 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 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. The functional currency of all other subsidiaries in Europe and other subsidiaries in Asia is the U.S.&nbsp;Dollar. While we believe risk to
fluctuations in foreign currency exchange rates for these subsidiaries is generally not significant, they can be subject to substantial currency changes, and therefore foreign exchange exposures. </P>

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 June&nbsp;30, 2018, 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:12pt; 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>

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 On May&amp;#xA0;25, 2018, the Company&amp;#x2019;s Board of Directors
 unanimously approved the merger of the Company with Picor
 Corporation (&amp;#x201C;Picor&amp;#x201D;), a subsidiary of Vicor, fully
 consolidated for financial reporting purposes, in which the Company
 was the majority stockholder. The merger was completed as of
 May&amp;#xA0;30, 2018, at which time the separate corporate existence
 of Picor ceased. To effect the merger, holders of Picor Common
 Stock and Picor stock options received an equivalent value of Vicor
 Common Stock and Vicor stock options, respectively, which caused
 the Picor Corporation Amended and Restated 2001 Stock Option and
 Incentive Plan, and options outstanding thereunder, to be assumed
 and restated by Vicor. While Picor&amp;#x2019;s subsidiary status and
 corporate form ceased to exist upon the closing of the merger, the
 operations previously conducted by Picor, which are now legally
 merged into Vicor, continue to be managed and remain categorized as
 a segment for financial reporting purposes. There was no net impact
 on the Company&amp;#x2019;s consolidated financial statements nor any
 impact on the Company&amp;#x2019;s segment reporting for the three and
 six months ended June&amp;#xA0;30, 2018 as a result of the merger.&lt;/p&gt;

 At June&amp;#xA0;30, 2018, the Company had approximately $2,044,000 of

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company is the defendant in a patent infringement lawsuit
 originally filed on January&amp;#xA0;28, 2011 by SynQor, Inc.
 (&amp;#x201C;SynQor&amp;#x201D;) in the U.S. District Court for the Eastern
 District of Texas (the &amp;#x201C;Texas Action&amp;#x201D;). The complaint,
 as amended in September 2011, alleges 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,
 7,564,702, and 8,023,290 (&amp;#x201C;the &amp;#x2018;190 patent&amp;#x201D;,
 &amp;#x201C;the &amp;#x2018;021 patent&amp;#x201D;, &amp;#x201C;the &amp;#x2018;702
 patent&amp;#x201D;, and &amp;#x201C;the &amp;#x2018;290 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.&amp;#xA0;The Company has denied that its products infringe any of
 the SynQor patents, asserted that the SynQor patents are invalid,
 and asserted that the &amp;#x2018;290 patent is unenforceable due to
 inequitable conduct by SynQor or its agents during the examination
 of the &amp;#x2018;290 patent&amp;#xA0;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. On May&amp;#xA0;23, 2016, after extensive
 discovery, the Texas Action was stayed by the court pending
 completion of certain inter partes reexamination proceedings at the
 USPTO (including any appeals from such proceedings to the Federal
 Circuit (as defined below)) concerning the SynQor patents, which
 are described below.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In response to the Texas Action, the Company initiated inter partes
 reexamination 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. The current status of these proceedings is as follows.
 Regarding the &amp;#x2018;190 patent, the United States Court of Appeals
 for the Federal Circuit (the &amp;#x201C;Federal Circuit&amp;#x201D;) issued
 a decision on March&amp;#xA0;13, 2015, determining that certain claims
 were invalid, and remanding the matter to the Patent Trial and
 Appeal Board (&amp;#x201C;PTAB&amp;#x201D;) of the USPTO 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). 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&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-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 On October&amp;#xA0;31, 2017, the Company filed a request with the
 USPTO for ex parte reexamination of the &amp;#x2018;702 patent, based on
 different prior art references than had been at issue in the
 previous inter parte reexamination of the &amp;#x2018;702 patent. On
 December&amp;#xA0;6, 2017, the USPTO issued a decision granting the
 Company&amp;#x2019;s request and initiating ex parte reexamination of
 the &amp;#x2018;702 patent. On March&amp;#xA0;21, 2018, the USPTO issued a
 &lt;font style="WHITE-SPACE: nowrap"&gt;non-final&lt;/font&gt; office action
 finding all of the challenged claims of the &amp;#x2018;702 patent to be
 unpatentable. On May&amp;#xA0;14, 2018, SynQor filed a petition asking
 the USPTO to vacate its prior decision granting the Company&amp;#x2019;s
 request for ex parte reexamination. No action has been taken on the
 petition to date. The Company continues to monitor the progress of
 this proceeding.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&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="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&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 overall increase in stock-based compensation between the 2018
 and 2017 periods was due to an increase in stock options granted
 between July&amp;#xA0;1, 2017 and June&amp;#xA0;30, 2018. The increase in
 selling, general and administrative stock-based compensation for
 the three and six months ended June&amp;#xA0;30, 2018, compared to the
 same periods in 2017, was also due to increased expense for certain
 Vicor stock options held by a &lt;font style="WHITE-SPACE: nowrap"&gt;non-employee.&lt;/font&gt; The fair value of these
 stock options, and related stock-based compensation, are adjusted
 monthly based on changes in the assumptions under the Black-Scholes
 option pricing model, including the price of the Company&amp;#x2019;s
 common stock, in accordance with the accounting for stock options
 granted to &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees.&lt;/font&gt;&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 June&amp;#xA0;30, 2018, 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 June&amp;#xA0;30, 2018. The
 major assumptions used in preparing the DCF model were similar to
 those described in Note 5 - Fair Value Measurements in the Notes to
 the Consolidated Financial Statements contained in the
 Company&amp;#x2019;s 2017 Form &lt;font style="WHITE-SPACE: nowrap"&gt;10-K.&lt;/font&gt;&lt;/p&gt;

 The effective tax rate was lower than the statutory tax rate in
 2018 due to the utilization of net operating carryforwards and tax
 credits. The provisions for income taxes in each 2017 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 these periods
 due to a full valuation allowance against all net domestic deferred
 tax assets. The provision and effective income tax rate were higher
 in the second quarter of 2017 as the Company had previously
 recorded a tax benefit in the first quarter of 2017.&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;
 On December&amp;#xA0;22, 2017, the U.S. government enacted
 comprehensive tax legislation, referred to as the Tax Cuts and Jobs
 Act (the &amp;#x201C;Tax Act&amp;#x201D;). The Tax Act makes broad and
 complex changes to the U.S. tax code, including, but not limited
 to: (1)&amp;#xA0;reducing the U.S. federal corporate tax rate from 35%
 to 21%; (2) elimination of the corporate alternative minimum tax
 (&amp;#x201C;AMT&amp;#x201D;) and changing how existing AMT credits can be
 realized; (3)&amp;#xA0;changing rules related to the usage and
 limitation of net operating loss carryforwards created in tax years
 beginning after December&amp;#xA0;31, 2017; and (4)&amp;#xA0;implementing a
 territorial tax system, which generally eliminates the U.S. federal
 income tax on dividends from foreign subsidiaries, and imposes
 &lt;font style="WHITE-SPACE: nowrap"&gt;a&amp;#xA0;one-time&amp;#xA0;transition&lt;/font&gt; tax on
 certain earnings of foreign subsidiaries previously untaxed in the
 United States.&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;
 Certain impacts of the Tax Act would generally require accounting
 to be completed in the period of enactment. However, in response to
 the complexities of the Tax Act, the Securities and Exchange
 Commission (&amp;#x201C;SEC&amp;#x201D;) issued guidance through Staff
 Accounting Bulletin No.&amp;#xA0;118 to provide companies with relief.
 Specifically, when the initial accounting for items under the Tax
 Act is incomplete, the guidance allows companies to include
 provisional amounts when reasonable estimates can be made. The SEC
 has provided up to &lt;font style="WHITE-SPACE: nowrap"&gt;a&amp;#xA0;one-year&amp;#xA0;measurement&lt;/font&gt;
 period for companies to finalize the accounting for the impact of
 the new legislation and the Company expects to finalize the
 accounting over the coming quarters. The Company has recognized the
 provisional tax impacts related to &lt;font style="WHITE-SPACE: nowrap"&gt;the&amp;#xA0;re-measurement&amp;#xA0;of&lt;/font&gt; its
 deferred tax assets and liabilities, &lt;font style="WHITE-SPACE: nowrap"&gt;and&amp;#xA0;one-time&amp;#xA0;transition&lt;/font&gt; tax,
 for the year ended December&amp;#xA0;31, 2017. The ultimate impact may
 differ from these provisional amounts due to, among other things,
 additional analysis, changes in interpretations and assumptions the
 Company has made, additional regulatory guidance that may be
 issued, and actions the Company may take as a result of the Tax
 Act. There were no changes to the provisional tax impacts referred
 to above in the first or second quarters of 2018.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 As of June&amp;#xA0;30, 2018, the Company continues to maintain a
 valuation allowance of approximately $33,024,000 against all
 domestic net deferred tax assets. Management assesses the need for
 the valuation allowance on a quarterly basis. In assessing the need
 for a valuation allowance, the Company considers all positive and
 negative evidence, including scheduled reversals of deferred tax
 liabilities, projected future taxable income, tax planning
 strategies, and past financial performance. Due to improving
 financial results, there is increasing positive evidence to support
 realization of deferred tax assets. Until actual operating results
 continue to be consistently positive, and the Company believes it
 is more likely than not it can forecast sufficient future taxable
 income of the appropriate nature to realize those deferred tax
 assets, it will continue to maintain the full valuation allowance
 position. If and when the Company determines the valuation
 allowance should be released (i.e., reduced), the adjustment would
 result in a tax benefit reported in that period&amp;#x2019;s
 consolidated statements of operations, the effect of which would be
 an increase in reported net income.&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 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 was completed in May
 2018 resulting in no tax liability to the Company. In January 2018,
 the Company received notice from the New York State Department of
 Taxation that its New York State tax returns for tax years 2014
 through 2016 were selected for audit. Onsite fieldwork for this
 audit was completed in May 2018, and the Company is awaiting the
 results of the audit.&lt;/p&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-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&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;

 As of June&amp;#xA0;30, 2018 and December&amp;#xA0;31, 2017, 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 June&amp;#xA0;30, 2018, 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 June&amp;#xA0;30, 2018.&lt;/p&gt;

 Based on the fair value measurements described in Note&amp;#xA0;5, the
 fair value of the Failed Auction Security on June&amp;#xA0;30, 2018,
 with a par value of $3,000,000, was estimated by the Company to be
 approximately $2,581,000. The gross unrealized loss of $419,000 on
 the Failed Auction Security consists of two types of estimated
 loss: an aggregate credit loss of $44,000 and an aggregate
 temporary impairment of $375,000. 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;5).&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;
 &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 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;

 In June 2018, the FASB issued new guidance&lt;i&gt;, Improvements to
 Nonemployee Share-Based Payment Accounting&lt;/i&gt; , which more closely
 aligns the accounting for share-based payments to &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees&lt;/font&gt; with the accounting for
 share-based payments to employees. This new guidance is effective
 for public business entities for annual and interim periods in
 fiscal years beginning after December&amp;#xA0;15, 2018. Early adoption
 is permitted, but no earlier than an entity&amp;#x2019;s adoption date
 of Topic 606.The Company is currently evaluating the impact this
 new guidance will have on its consolidated financial
 statements.&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 FASB 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
 adopted the new standard on January&amp;#xA0;1, 2018. The adoption of
 this new guidance did not 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 adopted the new standard on January&amp;#xA0;1,
 2018. The adoption of this new guidance did not have a material
 impact on its consolidated financial statements and related

 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 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 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 majority
 of the Company&amp;#x2019;s leases are for certain of its office and
 manufacturing space. The Company has developed an implementation
 plan and continues to gather information, including compiling an
 inventory of all leasing arrangements, to assess the impact of the
 new standard on its financial statements. 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 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;

 June&amp;#xA0;30, 2018 are not expected to have a material impact on

 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 has extended the warranty period to three years
 for certain military grade products sold after January&amp;#xA0;1,
 2017. The Company 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. 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;

 3. &lt;u&gt;Revenue Recognition&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;
 &lt;u&gt;Prior to January&lt;/u&gt;&lt;u&gt;&amp;#xA0;1, 2018&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;
 Product revenue was recognized in the period when persuasive
 evidence of an arrangement with a customer existed, the products
 were shipped and title was transferred to the customer, the price
 was fixed or determinable, and collection was considered
 probable.&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 Company deferred revenue and the related cost of sales on
 shipments to stocking distributors until the distributors resold
 the products to their customers. The agreements with these stocking
 distributors allowed them to receive price adjustment credits or to
 return qualifying products for credit, as determined by the
 Company, in order to reduce the amounts of slow-moving,
 discontinued, or obsolete product from their inventory. These
 stocking distributors were also granted price adjustment credits in
 the event of a price decrease subsequent to the date the product
 was shipped and invoiced to the stocking distributor. Given the
 uncertainties associated with the levels of price adjustment
 credits to be granted to stocking distributors, the sales price to
 the stocking distributor was not fixed or determinable until the
 stocking distributor resold the products to its customers.
 Therefore, the Company deferred revenue and the related cost of
 sales on shipments to stocking distributors until the stocking
 distributors resold the products to their customers. Accordingly,
 the Company&amp;#x2019;s revenue fully reflected &lt;font style="WHITE-SPACE: nowrap"&gt;end-customer&lt;/font&gt; purchases and was not
 impacted by stocking distributor inventory levels. Agreements with
 stocking distributors limited returns of qualifying product to the
 Company to a certain percentage of the value of the Company&amp;#x2019;s
 shipments to that stocking distributor during the prior quarter. In
 addition, stocking distributors were allowed to return unsold
 products if the Company terminated the relationship with the
 stocking distributor. Title to the inventory transferred to the
 stocking distributor at the time of shipment or delivery to the
 stocking distributor. Payment from the stocking distributors were
 due in accordance with the Company&amp;#x2019;s standard payment terms.
 These payment terms were not contingent upon the stocking
 distributors&amp;#x2019; sale of the products to their &lt;font style="WHITE-SPACE: nowrap"&gt;end-customers.&lt;/font&gt; Upon title transfer to
 stocking distributors, the Company reduced inventory for the cost
 of goods shipped, the margin (i.e., revenues less cost of revenues)
 was recorded as deferred revenue, and an account receivable was
 recorded. As of December&amp;#xA0;31, 2017, the Company had gross
 deferred revenue of approximately $4,659,000 and gross deferred
 cost of revenues of approximately $2,135,000 under agreements with
 stocking distributors.&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 Company evaluated revenue arrangements with potential
 multi-element deliverables to determine if there were more than one
 unit of accounting. A deliverable constituted a separate unit of
 accounting when it had standalone value and there were no
 customer-negotiated refund or return rights for the undelivered
 elements. The Company entered into arrangements containing multiple
 elements that could include a combination of &lt;font style="WHITE-SPACE: nowrap"&gt;non-recurring&lt;/font&gt; engineering services
 (&amp;#x201C;NRE&amp;#x201D;), prototype units, and production units. The
 Company determined NRE and prototype units represented one unit of
 accounting and production units represented a separate unit of
 accounting, based on an assessment of the respective standalone
 value. The Company deferred revenue recognition for NRE and
 prototype units until completion of the final milestone under the
 NRE arrangement, which was generally the delivery of the prototype.
 Recognition generally took place within six to twelve months of the
 initiation of the arrangement. Revenue for the production units was
 recognized upon shipment, consistent with other product revenue
 summarized above.&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;
 License fees were recognized as earned. The Company recognized
 revenue on such arrangements only when the contract was signed, the
 license term had begun, all obligations had been delivered to the
 customer, and collection was probable.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt; TEXT-INDENT: 4%"&gt;
 &lt;u&gt;Subsequent to January&lt;/u&gt;&lt;u&gt;&amp;#xA0;1, 2018&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;
 Revenue is recognized when control of the promised goods or
 services is transferred to a customer, in an amount that reflects
 the consideration the Company expects to be entitled to in exchange
 for those goods or services. Sales, value add, and other taxes
 collected concurrent with revenue-producing activities are excluded
 from revenue. The expected costs associated with product warranties
 continue to be recognized at the time product revenue is
 recognized. Shipping and handling costs associated with outbound
 freight after control over a product has transferred to a customer
 are accounted for as a fulfillment cost and are included in cost of
 revenues.&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 Company&amp;#x2019;s primary source of net revenue comes from the
 sale of products, which are modular power components and power
 systems for converting, regulating and controlling electric
 current. The principal customers for the Company&amp;#x2019;s power
 converters and systems are large original equipment manufacturers
 and the original design manufacturers and contract manufacturers
 serving them, and smaller, lower volume users, which are broadly
 distributed across several major market areas. The Company
 recognizes revenue for product sales at a point in time following
 the transfer of control of such products to the customer, which
 typically occurs upon shipment or delivery, depending on the terms
 of the underlying contract. As noted above, the Company previously
 deferred revenue and the related cost of revenues on shipments to
 stocking distributors until the distributors resold the products to
 their customers. The Company now records revenue for such
 transactions at the time of sale to the stocking distributor. The
 Company establishes sales allowances for estimated future product
 returns including distributor returns and price adjustment
 credits,&amp;#xA0;primarily based upon historical and anticipated rates
 of product returns and allowances.&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;
 Certain contracts with customers contain multiple performance
 obligations, which typically may include a combination of NRE,
 prototype units, and production units. For these contracts, the
 individual performance obligations are accounted for separately if
 they are distinct. Generally, the Company has determined the NRE
 and prototype units represent one distinct performance obligation
 and the production units represent a separate distinct performance
 obligation. For such arrangements, revenue is allocated to each
 performance obligation based on its relative standalone selling
 price, based on prices charged to customers or using the expected
 cost plus a margin approach. The Company defers revenue recognition
 for NRE and prototype units until the point in time at which the
 final milestone under the NRE arrangement is completed and control
 is transferred to the customer, which is generally the delivery of
 the prototype. Revenue for production units is recognized upon
 shipment or delivery, consistent with product revenue summarized
 above.&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 Company licenses its intellectual property under right to use
 licenses, in which royalties due to the Company are based upon a
 percentage of the licensee&amp;#x2019;s sales. The Company utilizes the
 exception under the revenue recognition guidance for the
 recognition of sales- or usage-based royalties, in which the
 royalties are not recognized until the later of when 1) the
 customer&amp;#x2019;s subsequent sales or usages occur, or 2) the
 performance obligation to which some or all of the sales- or
 usage-based royalty has been allocated is satisfied or partially
 satisfied.&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;
 Accounts receivable includes amounts billed and currently due from
 customers. The amounts due are stated at their estimated realizable
 value. The Company&amp;#x2019;s payment terms vary by the type and
 location of its customers and the products or services offered,
 although terms generally include a requirement of payment within 30
 to 60 days. The Company maintains allowances for doubtful accounts
 for estimated losses resulting from the inability of its customers
 to make required payments, based on assessments of customers&amp;#x2019;
 credit-risk profiles and payment histories. If the financial
 condition of the Company&amp;#x2019;s customers were to deteriorate,
 resulting in an impairment of their ability to make payments,
 additional allowances may be required. The Company does not require
 collateral from its customers, although there have been
 circumstances when the Company has required cash in advance (i.e.,
 a partial down-payment) to facilitate orders in excess of a
 customer&amp;#x2019;s established credit limit. To date, such amounts
 have not been material.&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 Company records deferred revenue, which represents a contract
 liability, when cash payments are received or due in advance of
 performance under a contract with a customer. During the three and
 six months ended June&amp;#xA0;30, 2018, under Topic 606, the Company
 recognized revenue of approximately $340,000 and $385,000,
 respectively, that was included in deferred revenue at the
 beginning of each respective period.&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 Company applies the practical expedient allowed under the new
 guidance for the incremental costs of obtaining a contract for
 sales commissions, which are expensed when incurred because the
 amortization period is generally less than one year. These costs
 are included in selling, general and administrative expenses.&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 Company also applies another practical expedient allowed under
 the new guidance and does not disclose the value of unsatisfied
 performance obligations for contracts with an original expected
 length of one year or less.&lt;/p&gt;

 The increase in accounts receivable was primarily due to an
 increase in net revenues of approximately $15,425,000 in the second
 quarter of 2018 compared to the fourth quarter of 2017. The
 decrease in deferred revenue was primarily due to the adoption of
 the new revenue recognition guidance, as the balances related to
 stocking distributors were reversed as part of the transition
 adjustment recorded as of January&amp;#xA0;1, 2018 (see Note 2 to the
 Condensed Consolidated Financial Statements). The increase in
 deferred expenses is primarily due to additional work incurred on
 certain NRE projects during the second quarter of 2018 for which
 the associated revenue is being deferred. The increase in sales
 allowances was due to the establishment of new allowances, in
 connection with the new revenue recognition guidance, for potential
 returns and price adjustment credits on sales to stocking
 distributors.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 8%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Deferred expenses are included in Other current assets, and
 customer prepayments are included in Deferred revenue, in the
 accompanying Condensed Consolidated Balance Sheets,
 respectively.&lt;/p&gt;

 In May 2018, the Company&amp;#x2019;s management authorized the closure
 of its Granite Power Technologies, Inc. (&amp;#x201C;GPT&amp;#x201D;)
 subsidiary, of the Brick Business Unit (&amp;#x201C;BBU&amp;#x201D;) segment,
 by the end of 2018. GPT, located in Manchester, N.H., is one of
 three Vicor Custom Power (&amp;#x201C;VCP&amp;#x201D;) entities. Certain of
 GPT&amp;#x2019;s products will continue to be manufactured and sold by
 the two remaining VCP entities. As a result, the Company recorded a
 &lt;font style="WHITE-SPACE: nowrap"&gt;pre-tax&lt;/font&gt; charge of $350,000
 in the second quarter of 2018, for the cost of severance and other
 employee-related costs involving cash payments based on each
 employee&amp;#x2019;s respective length of service. This was recorded as
 &amp;#x201C;Severance charge&amp;#x201D; in the Condensed Consolidated
 Statement of Operations. The related liability is presented as
 &amp;#x201C;Accrued severance charge&amp;#x201D; in the Condensed
 Consolidated Balance Sheets.&lt;/p&gt;

 The Company has organized its business segments according to its
 key product lines. The BBU segment designs, develops, manufactures,
 and markets the Company&amp;#x2019;s legacy lines of &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 in
 Japan through VJCL. The Picor segment, which consists of the
 operations of the Company&amp;#x2019;s former subsidiary Picor
 Corporation (see Note 13, above), designs, develops, manufactures,
 and markets integrated circuits for use in a variety of power
 management and power system applications. The Picor segment
 develops integrated circuits 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 Executive Officer (i.e., the 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;

 2. &lt;u&gt;Recently Adopted Accounting Standard&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 2014, the Financial Accounting Standards Board
 (&amp;#x201C;FASB&amp;#x201D;) issued new guidance for revenue recognition
 (&amp;#x201C;Topic 606&amp;#x201D;), which requires 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, replaces most of the
 prior revenue recognition guidance under U.S. Generally Accepted
 Accounting Principles. The Company adopted the new guidance as of
 January&amp;#xA0;1, 2018 using the modified retrospective method, as
 applied to all contracts. As a result, the Company has changed its
 accounting policy for revenue recognition, as detailed below. The
 most significant impact of the adoption was on the timing of
 recognition of sales to the Company&amp;#x2019;s stocking distributors
 and including the additional required disclosures under the new
 standard. Through December&amp;#xA0;31, 2017, the Company deferred
 revenue and the related cost of sales on shipments to stocking
 distributors until the distributors resold the products to their
 customers. Upon adoption, the Company is no longer permitted to
 defer revenue until sale by the stocking distributor to the end
 customer, but rather, is 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. In
 addition, the Company modified the accounting for a contractual
 arrangement due to a reassessment of the number of performance
 obligations in the arrangement, and adjusted for the timing of
 certain royalty revenue. The cumulative effect of adopting this
 guidance, recorded as an increase to the balance of retained
 earnings as of January&amp;#xA0;1, 2018, was approximately $3,670,000.
 The comparative information for the three and six months ended
 December&amp;#xA0;31, 2017, including disclosures, has not been
 restated and continues to be reported under the accounting
 standards in effect for that period.&lt;/p&gt;

 In May 2014, the Financial Accounting Standards Board
 (&amp;#x201C;FASB&amp;#x201D;) issued new guidance for revenue recognition
 (&amp;#x201C;Topic 606&amp;#x201D;), which requires 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, replaces most of the
 prior revenue recognition guidance under U.S. Generally Accepted
 Accounting Principles. The Company adopted the new guidance as of
 January&amp;#xA0;1, 2018 using the modified retrospective method, as
 applied to all contracts. As a result, the Company has changed its
 accounting policy for revenue recognition, as detailed below. The
 most significant impact of the adoption was on the timing of
 recognition of sales to the Company&amp;#x2019;s stocking distributors
 and including the additional required disclosures under the new
 standard. Through December&amp;#xA0;31, 2017, the Company deferred
 revenue and the related cost of sales on shipments to stocking
 distributors until the distributors resold the products to their
 customers. Upon adoption, the Company is no longer permitted to
 defer revenue until sale by the stocking distributor to the end
 customer, but rather, is 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. In
 addition, the Company modified the accounting for a contractual
 arrangement due to a reassessment of the number of performance
 obligations in the arrangement, and adjusted for the timing of
 certain royalty revenue. The cumulative effect of adopting this
 guidance, recorded as an increase to the balance of retained
 earnings as of January&amp;#xA0;1, 2018, was approximately $3,670,000.
 The comparative information for the three and six months ended
 December&amp;#xA0;31, 2017, including disclosures, has not been
 restated and continues to be reported under the accounting
 standards in effect for that period.&lt;/p&gt;

 In May 2014, the Financial Accounting Standards Board
 (&#x201C;FASB&#x201D;) issued new guidance for revenue recognition
 (&#x201C;Topic 606&#x201D;), which requires 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, replaces most of the
 prior revenue recognition guidance under U.S. Generally Accepted
 Accounting Principles. The Company adopted the new guidance as of
 January&#xA0;1, 2018 using the modified retrospective method, as
 applied to all contracts. As a result, the Company has changed its
 accounting policy for revenue recognition, as detailed below. The
 most significant impact of the adoption was on the timing of
 recognition of sales to the Company&#x2019;s stocking distributors
 and including the additional required disclosures under the new
 standard. Through December&#xA0;31, 2017, the Company deferred
 revenue and the related cost of sales on shipments to stocking
 distributors until the distributors resold the products to their
 customers. Upon adoption, the Company is no longer permitted to
 defer revenue until sale by the stocking distributor to the end
 customer, but rather, is 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. In
 addition, the Company modified the accounting for a contractual
 arrangement due to a reassessment of the number of performance
 obligations in the arrangement, and adjusted for the timing of
 certain royalty revenue. The cumulative effect of adopting this
 guidance, recorded as an increase to the balance of retained
 earnings as of January&#xA0;1, 2018, was approximately $3,670,000.
 The comparative information for the three and six months ended
 December&#xA0;31, 2017, including disclosures, has not been
 restated and continues to be reported under the accounting
 standards in effect for that period.</p>

 Product revenue was recognized in the period when persuasive
 evidence of an arrangement with a customer existed, the products
 were shipped and title was transferred to the customer, the price
 was fixed or determinable, and collection was considered
 probable.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company deferred revenue and the related cost of sales on
 shipments to stocking distributors until the distributors resold
 the products to their customers. The agreements with these stocking
 distributors allowed them to receive price adjustment credits or to
 return qualifying products for credit, as determined by the
 Company, in order to reduce the amounts of slow-moving,
 discontinued, or obsolete product from their inventory. These
 stocking distributors were also granted price adjustment credits in
 the event of a price decrease subsequent to the date the product
 was shipped and invoiced to the stocking distributor. Given the
 uncertainties associated with the levels of price adjustment
 credits to be granted to stocking distributors, the sales price to
 the stocking distributor was not fixed or determinable until the
 stocking distributor resold the products to its customers.
 Therefore, the Company deferred revenue and the related cost of
 sales on shipments to stocking distributors until the stocking
 distributors resold the products to their customers. Accordingly,
 the Company&#x2019;s revenue fully reflected <font style="WHITE-SPACE: nowrap">end-customer</font> purchases and was not
 impacted by stocking distributor inventory levels. Agreements with
 stocking distributors limited returns of qualifying product to the
 Company to a certain percentage of the value of the Company&#x2019;s
 shipments to that stocking distributor during the prior quarter. In
 addition, stocking distributors were allowed to return unsold
 products if the Company terminated the relationship with the
 stocking distributor. Title to the inventory transferred to the
 stocking distributor at the time of shipment or delivery to the
 stocking distributor. Payment from the stocking distributors were
 due in accordance with the Company&#x2019;s standard payment terms.
 These payment terms were not contingent upon the stocking
 distributors&#x2019; sale of the products to their <font style="WHITE-SPACE: nowrap">end-customers.</font> Upon title transfer to
 stocking distributors, the Company reduced inventory for the cost
 of goods shipped, the margin (i.e., revenues less cost of revenues)
 was recorded as deferred revenue, and an account receivable was
 recorded. As of December&#xA0;31, 2017, the Company had gross
 deferred revenue of approximately $4,659,000 and gross deferred
 cost of revenues of approximately $2,135,000 under agreements with
 stocking distributors.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company evaluated revenue arrangements with potential
 multi-element deliverables to determine if there were more than one
 unit of accounting. A deliverable constituted a separate unit of
 accounting when it had standalone value and there were no
 customer-negotiated refund or return rights for the undelivered
 elements. The Company entered into arrangements containing multiple
 elements that could include a combination of <font style="WHITE-SPACE: nowrap">non-recurring</font> engineering services
 (&#x201C;NRE&#x201D;), prototype units, and production units. The
 Company determined NRE and prototype units represented one unit of
 accounting and production units represented a separate unit of
 accounting, based on an assessment of the respective standalone
 value. The Company deferred revenue recognition for NRE and
 prototype units until completion of the final milestone under the
 NRE arrangement, which was generally the delivery of the prototype.
 Recognition generally took place within six to twelve months of the
 initiation of the arrangement. Revenue for the production units was
 recognized upon shipment, consistent with other product revenue
 summarized above.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 License fees were recognized as earned. The Company recognized
 revenue on such arrangements only when the contract was signed, the
 license term had begun, all obligations had been delivered to the
 customer, and collection was probable.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt; TEXT-INDENT: 4%">

 Revenue is recognized when control of the promised goods or
 services is transferred to a customer, in an amount that reflects
 the consideration the Company expects to be entitled to in exchange
 for those goods or services. Sales, value add, and other taxes
 collected concurrent with revenue-producing activities are excluded
 from revenue. The expected costs associated with product warranties
 continue to be recognized at the time product revenue is
 recognized. Shipping and handling costs associated with outbound
 freight after control over a product has transferred to a customer
 are accounted for as a fulfillment cost and are included in cost of
 revenues.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company&#x2019;s primary source of net revenue comes from the
 sale of products, which are modular power components and power
 systems for converting, regulating and controlling electric
 current. The principal customers for the Company&#x2019;s power
 converters and systems are large original equipment manufacturers
 and the original design manufacturers and contract manufacturers
 serving them, and smaller, lower volume users, which are broadly
 distributed across several major market areas. The Company
 recognizes revenue for product sales at a point in time following
 the transfer of control of such products to the customer, which
 typically occurs upon shipment or delivery, depending on the terms
 of the underlying contract. As noted above, the Company previously
 deferred revenue and the related cost of revenues on shipments to
 stocking distributors until the distributors resold the products to
 their customers. The Company now records revenue for such
 transactions at the time of sale to the stocking distributor. The
 Company establishes sales allowances for estimated future product
 returns including distributor returns and price adjustment
 credits,&#xA0;primarily based upon historical and anticipated rates
 of product returns and allowances.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 Certain contracts with customers contain multiple performance
 obligations, which typically may include a combination of NRE,
 prototype units, and production units. For these contracts, the
 individual performance obligations are accounted for separately if
 they are distinct. Generally, the Company has determined the NRE
 and prototype units represent one distinct performance obligation
 and the production units represent a separate distinct performance
 obligation. For such arrangements, revenue is allocated to each
 performance obligation based on its relative standalone selling
 price, based on prices charged to customers or using the expected
 cost plus a margin approach. The Company defers revenue recognition
 for NRE and prototype units until the point in time at which the
 final milestone under the NRE arrangement is completed and control
 is transferred to the customer, which is generally the delivery of
 the prototype. Revenue for production units is recognized upon
 shipment or delivery, consistent with product revenue summarized
 above.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company licenses its intellectual property under right to use
 licenses, in which royalties due to the Company are based upon a
 percentage of the licensee&#x2019;s sales. The Company utilizes the
 exception under the revenue recognition guidance for the
 recognition of sales- or usage-based royalties, in which the
 royalties are not recognized until the later of when 1) the
 customer&#x2019;s subsequent sales or usages occur, or 2) the
 performance obligation to which some or all of the sales- or
 usage-based royalty has been allocated is satisfied or partially
 satisfied.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 Accounts receivable includes amounts billed and currently due from
 customers. The amounts due are stated at their estimated realizable
 value. The Company&#x2019;s payment terms vary by the type and
 location of its customers and the products or services offered,
 although terms generally include a requirement of payment within 30
 to 60 days. The Company maintains allowances for doubtful accounts
 for estimated losses resulting from the inability of its customers
 to make required payments, based on assessments of customers&#x2019;
 credit-risk profiles and payment histories. If the financial
 condition of the Company&#x2019;s customers were to deteriorate,
 resulting in an impairment of their ability to make payments,
 additional allowances may be required. The Company does not require
 collateral from its customers, although there have been
 circumstances when the Company has required cash in advance (i.e.,
 a partial down-payment) to facilitate orders in excess of a
 customer&#x2019;s established credit limit. To date, such amounts
 have not been material.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company records deferred revenue, which represents a contract
 liability, when cash payments are received or due in advance of
 performance under a contract with a customer. During the three and
 six months ended June&#xA0;30, 2018, under Topic 606, the Company
 recognized revenue of approximately $340,000 and $385,000,
 respectively, that was included in deferred revenue at the
 beginning of each respective period.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company applies the practical expedient allowed under the new
 guidance for the incremental costs of obtaining a contract for
 sales commissions, which are expensed when incurred because the
 amortization period is generally less than one year. These costs
 are included in selling, general and administrative expenses.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company also applies another practical expedient allowed under
 the new guidance and does not disclose the value of unsatisfied
 performance obligations for contracts with an original expected
 length of one year or less.</p>

 The increase in accounts receivable was primarily due to an
 increase in net revenues of approximately $15,425,000 in the second
 quarter of 2018 compared to the fourth quarter of 2017. The
 decrease in deferred revenue was primarily due to the adoption of
 the new revenue recognition guidance, as the balances related to
 stocking distributors were reversed as part of the transition
 adjustment recorded as of January&#xA0;1, 2018 (see Note 2 to the
 Condensed Consolidated Financial Statements). The increase in
 deferred expenses is primarily due to additional work incurred on
 certain NRE projects during the second quarter of 2018 for which
 the associated revenue is being deferred. The increase in sales
 allowances was due to the establishment of new allowances, in
 connection with the new revenue recognition guidance, for potential
 returns and price adjustment credits on sales to stocking
 distributors.</p>

 Deferred expenses are included in Other current assets, and
 customer prepayments are included in Deferred revenue, in the

 As of June&#xA0;30, 2018 and December&#xA0;31, 2017, 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 June&#xA0;30, 2018, 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 June&#xA0;30, 2018.</p>

 Based on the fair value measurements described in Note&#xA0;5, the
 fair value of the Failed Auction Security on June&#xA0;30, 2018,
 with a par value of $3,000,000, was estimated by the Company to be
 approximately $2,581,000. The gross unrealized loss of $419,000 on
 the Failed Auction Security consists of two types of estimated
 loss: an aggregate credit loss of $44,000 and an aggregate
 temporary impairment of $375,000. 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;5).</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>

 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 June&#xA0;30, 2018, 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 June&#xA0;30, 2018. The
 major assumptions used in preparing the DCF model were similar to
 those described in Note 5 - Fair Value Measurements in the Notes to
 the Consolidated Financial Statements contained in the
 Company&#x2019;s 2017 Form <font style="WHITE-SPACE: nowrap">10-K.</font></p>

 The overall increase in stock-based compensation between the 2018
 and 2017 periods was due to an increase in stock options granted
 between July&#xA0;1, 2017 and June&#xA0;30, 2018. The increase in
 selling, general and administrative stock-based compensation for
 the three and six months ended June&#xA0;30, 2018, compared to the
 same periods in 2017, was also due to increased expense for certain
 Vicor stock options held by a <font style="WHITE-SPACE: nowrap">non-employee.</font> The fair value of these
 stock options, and related stock-based compensation, are adjusted
 monthly based on changes in the assumptions under the Black-Scholes
 option pricing model, including the price of the Company&#x2019;s
 common stock, in accordance with the accounting for stock options
 granted to <font style="WHITE-SPACE: nowrap">non-employees.</font></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-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 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 has extended the warranty period to three years
 for certain military grade products sold after January&#xA0;1,
 2017. The Company 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. 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>

 In May 2018, the Company&#x2019;s management authorized the closure
 of its Granite Power Technologies, Inc. (&#x201C;GPT&#x201D;)
 subsidiary, of the Brick Business Unit (&#x201C;BBU&#x201D;) segment,
 by the end of 2018. GPT, located in Manchester, N.H., is one of
 three Vicor Custom Power (&#x201C;VCP&#x201D;) entities. Certain of
 GPT&#x2019;s products will continue to be manufactured and sold by
 the two remaining VCP entities. As a result, the Company recorded a
 <font style="WHITE-SPACE: nowrap">pre-tax</font> charge of $350,000
 in the second quarter of 2018, for the cost of severance and other
 employee-related costs involving cash payments based on each
 employee&#x2019;s respective length of service. This was recorded as
 &#x201C;Severance charge&#x201D; in the Condensed Consolidated
 Statement of Operations. The related liability is presented as
 &#x201C;Accrued severance charge&#x201D; in the Condensed
 Consolidated Balance Sheets.</p>

 The effective tax rate was lower than the statutory tax rate in
 2018 due to the utilization of net operating carryforwards and tax
 credits. The provisions for income taxes in each 2017 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&#x2019;s losses during these periods
 due to a full valuation allowance against all net domestic deferred
 tax assets. The provision and effective income tax rate were higher
 in the second quarter of 2017 as the Company had previously
 recorded a tax benefit in the first quarter of 2017.</p>

 On December&#xA0;22, 2017, the U.S. government enacted
 comprehensive tax legislation, referred to as the Tax Cuts and Jobs
 Act (the &#x201C;Tax Act&#x201D;). The Tax Act makes broad and
 complex changes to the U.S. tax code, including, but not limited
 to: (1)&#xA0;reducing the U.S. federal corporate tax rate from 35%
 to 21%; (2) elimination of the corporate alternative minimum tax
 (&#x201C;AMT&#x201D;) and changing how existing AMT credits can be
 realized; (3)&#xA0;changing rules related to the usage and
 limitation of net operating loss carryforwards created in tax years
 beginning after December&#xA0;31, 2017; and (4)&#xA0;implementing a
 territorial tax system, which generally eliminates the U.S. federal
 income tax on dividends from foreign subsidiaries, and imposes
 <font style="WHITE-SPACE: nowrap">a&#xA0;one-time&#xA0;transition</font> tax on
 certain earnings of foreign subsidiaries previously untaxed in the
 United States.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 Certain impacts of the Tax Act would generally require accounting
 to be completed in the period of enactment. However, in response to
 the complexities of the Tax Act, the Securities and Exchange
 Commission (&#x201C;SEC&#x201D;) issued guidance through Staff
 Accounting Bulletin No.&#xA0;118 to provide companies with relief.
 Specifically, when the initial accounting for items under the Tax
 Act is incomplete, the guidance allows companies to include
 provisional amounts when reasonable estimates can be made. The SEC
 has provided up to <font style="WHITE-SPACE: nowrap">a&#xA0;one-year&#xA0;measurement</font>
 period for companies to finalize the accounting for the impact of
 the new legislation and the Company expects to finalize the
 accounting over the coming quarters. The Company has recognized the
 provisional tax impacts related to <font style="WHITE-SPACE: nowrap">the&#xA0;re-measurement&#xA0;of</font> its
 deferred tax assets and liabilities, <font style="WHITE-SPACE: nowrap">and&#xA0;one-time&#xA0;transition</font> tax,
 for the year ended December&#xA0;31, 2017. The ultimate impact may
 differ from these provisional amounts due to, among other things,
 additional analysis, changes in interpretations and assumptions the
 Company has made, additional regulatory guidance that may be
 issued, and actions the Company may take as a result of the Tax
 Act. There were no changes to the provisional tax impacts referred
 to above in the first or second quarters of 2018.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
 As of June&#xA0;30, 2018, the Company continues to maintain a
 valuation allowance of approximately $33,024,000 against all
 domestic net deferred tax assets. Management assesses the need for
 the valuation allowance on a quarterly basis. In assessing the need
 for a valuation allowance, the Company considers all positive and
 negative evidence, including scheduled reversals of deferred tax
 liabilities, projected future taxable income, tax planning
 strategies, and past financial performance. Due to improving
 financial results, there is increasing positive evidence to support
 realization of deferred tax assets. Until actual operating results
 continue to be consistently positive, and the Company believes it
 is more likely than not it can forecast sufficient future taxable
 income of the appropriate nature to realize those deferred tax
 assets, it will continue to maintain the full valuation allowance
 position. If and when the Company determines the valuation
 allowance should be released (i.e., reduced), the adjustment would
 result in a tax benefit reported in that period&#x2019;s
 consolidated statements of operations, the effect of which would be
 an increase in reported net income.</p>

 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 was completed in May
 2018 resulting in no tax liability to the Company. In January 2018,
 the Company received notice from the New York State Department of
 Taxation that its New York State tax returns for tax years 2014
 through 2016 were selected for audit. Onsite fieldwork for this
 audit was completed in May 2018, and the Company is awaiting the
 results of the audit.</p>

 The Company is the defendant in a patent infringement lawsuit
 originally filed on January&#xA0;28, 2011 by SynQor, Inc.
 (&#x201C;SynQor&#x201D;) in the U.S. District Court for the Eastern
 District of Texas (the &#x201C;Texas Action&#x201D;). The complaint,
 as amended in September 2011, alleges that the Company&#x2019;s
 products, including but not limited to, unregulated bus converters
 used in intermediate bus architecture power supply systems,
 infringe SynQor&#x2019;s U.S. patent numbers 7,072,190, 7,272,021,
 7,564,702, and 8,023,290 (&#x201C;the &#x2018;190 patent&#x201D;,
 &#x201C;the &#x2018;021 patent&#x201D;, &#x201C;the &#x2018;702
 patent&#x201D;, and &#x201C;the &#x2018;290 patent&#x201D;,
 respectively). SynQor&#x2019;s complaint sought an injunction
 against further infringement and an award of unspecified
 compensatory and enhanced damages, interest, costs and attorney
 fees.&#xA0;The Company has denied that its products infringe any of
 the SynQor patents, asserted that the SynQor patents are invalid,
 and asserted that the &#x2018;290 patent is unenforceable due to
 inequitable conduct by SynQor or its agents during the examination
 of the &#x2018;290 patent&#xA0;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. On May&#xA0;23, 2016, after extensive
 discovery, the Texas Action was stayed by the court pending
 completion of certain inter partes reexamination proceedings at the
 USPTO (including any appeals from such proceedings to the Federal
 Circuit (as defined below)) concerning the SynQor patents, which
 are described below.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In response to the Texas Action, the Company initiated inter partes
 reexamination 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. The current status of these proceedings is as follows.
 Regarding the &#x2018;190 patent, the United States Court of Appeals
 for the Federal Circuit (the &#x201C;Federal Circuit&#x201D;) issued
 a decision on March&#xA0;13, 2015, determining that certain claims
 were invalid, and remanding the matter to the Patent Trial and
 Appeal Board (&#x201C;PTAB&#x201D;) of the USPTO for further
 proceedings. On 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). 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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
 On October&#xA0;31, 2017, the Company filed a request with the
 USPTO for ex parte reexamination of the &#x2018;702 patent, based on
 different prior art references than had been at issue in the
 previous inter parte reexamination of the &#x2018;702 patent. On
 December&#xA0;6, 2017, the USPTO issued a decision granting the
 Company&#x2019;s request and initiating ex parte reexamination of
 the &#x2018;702 patent. On March&#xA0;21, 2018, the USPTO issued a
 <font style="WHITE-SPACE: nowrap">non-final</font> office action
 finding all of the challenged claims of the &#x2018;702 patent to be
 unpatentable. On May&#xA0;14, 2018, SynQor filed a petition asking
 the USPTO to vacate its prior decision granting the Company&#x2019;s
 request for ex parte reexamination. No action has been taken on the
 petition to date. The Company continues to monitor the progress of
 this proceeding.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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>

 On May&#xA0;25, 2018, the Company&#x2019;s Board of Directors
 unanimously approved the merger of the Company with Picor
 Corporation (&#x201C;Picor&#x201D;), a subsidiary of Vicor, fully
 consolidated for financial reporting purposes, in which the Company
 was the majority stockholder. The merger was completed as of
 May&#xA0;30, 2018, at which time the separate corporate existence
 of Picor ceased. To effect the merger, holders of Picor Common
 Stock and Picor stock options received an equivalent value of Vicor
 Common Stock and Vicor stock options, respectively, which caused
 the Picor Corporation Amended and Restated 2001 Stock Option and
 Incentive Plan, and options outstanding thereunder, to be assumed
 and restated by Vicor. While Picor&#x2019;s subsidiary status and
 corporate form ceased to exist upon the closing of the merger, the
 operations previously conducted by Picor, which are now legally
 merged into Vicor, continue to be managed and remain categorized as
 a segment for financial reporting purposes. There was no net impact
 on the Company&#x2019;s consolidated financial statements nor any
 impact on the Company&#x2019;s segment reporting for the three and
 six months ended June&#xA0;30, 2018 as a result of the merger.</p>

 The Company has organized its business segments according to its
 key product lines. The BBU segment designs, develops, manufactures,
 and markets the Company&#x2019;s legacy lines of <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.
 (&#x201C;VJCL&#x201D;). The VI Chip segment includes VI Chip
 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 in
 Japan through VJCL. The Picor segment, which consists of the
 operations of the Company&#x2019;s former subsidiary Picor
 Corporation (see Note 13, above), designs, develops, manufactures,
 and markets integrated circuits for use in a variety of power
 management and power system applications. The Picor segment
 develops integrated circuits 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) applications.</p>

 The Company&#x2019;s Chief Executive Officer (i.e., the 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>

 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

 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 majority
 of the Company&#x2019;s leases are for certain of its office and
 manufacturing space. The Company has developed an implementation
 plan and continues to gather information, including compiling an
 inventory of all leasing arrangements, to assess the impact of the
 new standard on its financial statements. 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

 In May 2014, the Financial Accounting Standards Board
 (&#x201C;FASB&#x201D;) issued new guidance for revenue recognition
 (&#x201C;Topic 606&#x201D;), which requires 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, replaces most of the
 prior revenue recognition guidance under U.S. Generally Accepted
 Accounting Principles. The Company adopted the new guidance as of
 January&#xA0;1, 2018 using the modified retrospective method, as
 applied to all contracts. As a result, the Company has changed its
 accounting policy for revenue recognition, as detailed below. The
 most significant impact of the adoption was on the timing of
 recognition of sales to the Company&#x2019;s stocking distributors
 and including the additional required disclosures under the new
 standard. Through December&#xA0;31, 2017, the Company deferred
 revenue and the related cost of sales on shipments to stocking
 distributors until the distributors resold the products to their
 customers. Upon adoption, the Company is no longer permitted to
 defer revenue until sale by the stocking distributor to the end
 customer, but rather, is 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. In
 addition, the Company modified the accounting for a contractual
 arrangement due to a reassessment of the number of performance
 obligations in the arrangement, and adjusted for the timing of
 certain royalty revenue. The cumulative effect of adopting this
 guidance, recorded as an increase to the balance of retained
 earnings as of January&#xA0;1, 2018, was approximately $3,670,000.
 The comparative information for the three and six months ended
 December&#xA0;31, 2017, including disclosures, has not been
 restated and continues to be reported under the accounting
 standards in effect for that period.</p>
