PROXY STATEMENT

FOR THE 2013 ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON FRIDAY, JUNE 21, 2013

April 18, 2013

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors (the “Board” and each member thereof being a “Director”) of Vicor Corporation (the “Corporation”) from owners of the outstanding shares of capital stock of the Corporation (the “Stockholders”, or as an individual, a “Stockholder”) for use at the 2013 Annual Meeting of Stockholders (the “Annual Meeting”) of the Corporation to be held on Friday, June 21, 2013, at 9:00 a.m., local time, at the offices of Foley & Lardner LLP, 111 Huntington Avenue, Boston, Massachusetts 02199, and at any adjournments or postponements thereof. At the Annual Meeting, Stockholders will be asked to consider and vote on the proposals set forth in this Proxy Statement.

This Proxy Statement and the accompanying Notice of Annual Meeting and Proxy Card are first being sent to Stockholders on or about May 10, 2013. The Board of Directors has fixed the close of business on April 30, 2013, as the record date for the determination of Stockholders entitled to receive notice of and to vote at the Annual Meeting (the “Record Date”). Only Stockholders of record at the close of business on the Record Date will be entitled to receive notice of and to vote at the Annual Meeting. As of March 31, 2013, there were 28,112,264 shares of Common Stock and 11,767,052 shares of Class B Common Stock of the Corporation outstanding and entitled to vote. Each share of Common Stock entitles the holder thereof to one vote per share and each share of Class B Common Stock entitles the holder thereof to 10 votes per share. Shares of Common Stock and Class B Common Stock will vote together as a single class on the proposals set forth in this Proxy Statement.

Stockholders of the Corporation are requested to complete, date, sign and return the accompanying Proxy Card in the enclosed postage-prepaid envelope. Shares represented by a properly executed Proxy Card received prior to the vote at the Annual Meeting and not revoked will be voted at the Annual Meeting as directed on the Proxy Card. If a properly executed Proxy Card is submitted and no instructions are given, the shares so represented will be voted FOR the election of each Director candidate set forth herein. It is not anticipated any matters other than those set forth in this Proxy Statement will be presented at the Annual Meeting. If other matters are presented, proxies will be voted in accordance with the discretion of the proxy holders.

A Stockholder of record may revoke a proxy at any time before it has been exercised by: (1) filing a written revocation with the Secretary of the Corporation at the address of the Corporation set forth above; (2) filing a duly executed proxy bearing a later date; or (3) appearing in person, notifying the Secretary and voting by ballot at the Annual Meeting. Any Stockholder of record as of the Record Date attending the Annual Meeting may vote in person whether or not a proxy has been previously given, but the presence (without further action) of a Stockholder at the Annual Meeting will not constitute revocation of a previously given proxy. The presence, in person or by proxy, of Stockholders of a majority in interest of all capital stock issued, outstanding and entitled to vote at the Annual Meeting shall constitute a quorum for the transaction of business at the Annual Meeting. Shares that reflect abstentions or “broker non-votes” (i.e., shares held by investment brokerage firms or other nominees that are represented at the Annual Meeting but as to which such brokers or nominees have not received instructions from the beneficial owners or persons entitled to vote such shares and, with respect to one or more but not all matters, such brokers or nominees do not have discretionary voting power to vote such shares) will be counted for purposes of determining whether a quorum is present for the transaction of business at the Annual Meeting.

The cost of solicitation of proxies in the form enclosed herewith will be borne by the Corporation. In addition to the solicitation of proxies by mail, Directors, officers and employees of the Corporation may also solicit proxies personally or by telephone, e-mail or other form of electronic communication without special compensation for such activities. The Corporation will also request those holding shares in their names or in the names of their nominees that are beneficially owned by others to send proxy materials to and obtain proxies from such beneficial owners. The Corporation will reimburse such holders for their reasonable expenses in connection therewith.

The Corporation’s 2012 Annual Report (the “Annual Report”), including financial statements for the fiscal year ended December 31, 2012, will be mailed to Stockholders concurrently with this Proxy Statement. The Annual Report, however, is not part of the proxy solicitation materials. The Corporation and certain intermediaries (e.g. banks, brokers, and nominees) may deliver only one copy of the Annual Report and Proxy Statement to Stockholders sharing an address. The Corporation will deliver promptly, upon written or oral request, a separate copy of the Annual Report or Proxy Statement, as applicable, to a Stockholder at a shared address to which a single copy of the document was delivered. In order to receive such a separate copy, please contact the Corporation’s Secretary at 25 Frontage Road, Andover, Massachusetts or (978) 470-2900. If Stockholders sharing an address (i) currently receive a single copy of the Annual Report and Proxy Statement and wish to receive separate copies of such materials in the future or (ii) currently receive separate copies of the Annual Report and Proxy Statement and wish to receive a single copy of such materials in the future, please contact the Corporation’s Secretary as set forth above or the applicable intermediary, as the case may be.

Important notice regarding the availability of proxy materials for the Annual Meeting to be held on June 21, 2013:

The Proxy Statement and Annual Report to Stockholders is available at www.vicorpower.com/proxy.

PROPOSAL 1

ELECTION OF DIRECTORS

The Board of the Corporation has recommended the number of Directors be fixed at nine and has nominated the nine individuals named below for election as Directors. Each of the nominees is presently serving as a Director of the Corporation. If elected, each nominee will serve until the 2014 Annual Meeting of Stockholders and until his respective successor is duly elected and qualified or until his death, resignation or removal. Properly executed Proxy Cards will be voted for the nominees named below unless otherwise specified. The Board anticipates each of the nominees, if elected, will serve as a Director. However, if any person nominated by the Board is unable to serve or for good cause will not serve, proxies solicited hereby will be voted for the election of another person designated by the Board, if one is nominated. A plurality of the votes cast by the Stockholders of Common Stock and Class B Common Stock, voting together as a single class, for a nominee for Director shall elect such nominee. Accordingly, abstentions, broker non-votes, and votes withheld from any nominee will have no effect on this proposal.

Dr. Patrizio Vinciarelli, Chairman of the Board, President, and Chief Executive Officer, beneficially owned, as of March 7, 2013, 9,675,480 shares of Common Stock and 11,023,648 shares of Class B Common Stock, together representing 82.2% of the voting power of the outstanding stock of the Corporation, sufficient to elect each of the nominees named below, and has indicated an intention to vote in favor of fixing the number of Directors at nine and the election of all nominees.

The Board unanimously recommends a vote FOR fixing the number of Directors at nine and the election of all of the nominees.

CORPORATE GOVERNANCE

The Board and Its Committees

The Corporation is a “controlled company” in accordance with the corporate governance rules contained in the Marketplace Rules of the Nasdaq OMX Group, Inc. (the “NASDAQ Rules”) because Dr. Vinciarelli, Chairman of the Board, President, and Chief Executive Officer, holds more than 50% of the voting power of the outstanding capital stock of the Corporation. As a result, the Corporation is not required to have (1) a majority of independent Directors on its Board of Directors, (2) the compensation of its executive officers determined by independent Directors, nor (3) its Director nominees selected or recommended by independent Directors. The Board has determined four of its nine Directors (Messrs. Carlson, Eichten, Griffin and Riddiford) are independent Directors for purposes of the NASDAQ Rules. The Corporation does not have a lead independent director.

Due to the Corporation status as a controlled company and Dr. Vinciarelli’s leadership of the Corporation since its founding, Dr. Vinciarelli fulfills both the roles of Chief Executive Officer and Chairman of the Board. As Chief Executive, he is responsible for setting the strategic direction of the Corporation and the day to day leadership and performance of the Corporation. As Chairman of the Board, Dr. Vinciarelli presides over meetings of the Board and, in collaboration with Mr. Simms, in his capacity as Secretary of the Corporation, establishes an agenda for each meeting.

The Board held five meetings during 2012. Each of the Directors attended 75% or more of the total number of meetings of the Board and meetings of the committees thereof on which each such Director serves. Directors are expected to attend each year’s Annual Meeting in person unless doing so is impracticable due to unavoidable conflicts. All of the Directors attended the 2012 Annual Meeting of Stockholders.

The Board has established an Audit Committee and an Executive Compensation Committee. The Board does not have a standing Nominating Committee because it believes the Board as a whole is in the best position to evaluate potential Director nominees and, therefore, it is not necessary for the Corporation to have a separate committee responsible for such evaluations. The full Board performs the function of such a committee.

The Audit Committee is composed of Messrs. Carlson, Eichten, Griffin and Riddiford. Information regarding the functions performed by the Audit Committee is set forth in the section of this Proxy Statement

entitled “Report of the Audit Committee”. The Audit Committee is governed by a written charter approved by the Board on February 3, 2007. The Board has determined all four members of the Audit Committee are “independent” under the applicable NASDAQ Rules and rules of the United States Securities and Exchange Commission (the “SEC”). The Board also has determined one of the present members of the Audit Committee, Mr. Carlson, meets the definition of “audit committee financial expert” as defined by Item 407(d) of Regulation S-K promulgated by the SEC. The Audit Committee charter is posted on the Corporation’s website, www.vicorpower.com, under the heading “Company” and the subheading “Corporate Governance”. The Audit Committee held six meetings during 2012.

The Executive Compensation Committee is composed of Messrs. Carlson, Eichten, Griffin and Riddiford. The Executive Compensation Committee is responsible for establishing, based on the recommendation of the Corporation’s Chief Executive Officer, salaries, bonuses and other compensation for the officers of the Corporation, approving all grants of stock options by the Corporation and its subsidiaries, and administering the Corporation’s stock option and bonus plans pursuant to authority delegated to it by the Board. The Executive Compensation Committee held three meetings during 2012 and acted by written consent in lieu of meetings on 24 occasions to approve stock option awards granted during 2012. The Executive Compensation Committee does not have a written charter.

The Board has an active role, as a whole and also at the committee level, in overseeing management of the Corporation’s risks. The Board regularly reviews information regarding the Corporation’s strategy, operations, financial position, and legal affairs, addressing the risks associated with each.

While the Board is ultimately responsible for the Corporation’s risk analysis and risk management procedures, the Audit Committee assists the Board in overseeing such responsibilities, with particular focus on the integrity and effectiveness of the Corporation’s financial reporting processes. The Audit Committee reviews guidelines and policies on enterprise risk management, including risk assessment and risk management related to the Corporation’s major financial risk exposures and management’s monitoring and control of such exposures. At each meeting of the Audit Committee, management presents information addressing issues related to risk analysis and risk management.

In addition to the risk oversight role undertaken by the Audit Committee, the Executive Compensation Committee assists the Board in overseeing the Corporation’s compensation policies and practices as they relate to the Corporation’s risk management and risk-taking incentives. The Executive Compensation Committee has determined the compensation policies and practices for the Corporation’s employees are not reasonably likely to have a material adverse effect on the Corporation.

Director Nomination Process

The full Board performs the Director nomination function for the Corporation. The Board does not have a charter governing the Director nomination process, although it has established Director nomination procedures setting forth the current process for identifying and evaluating Director nominees.

Board Membership Criteria — At a minimum, the Board must be satisfied each nominee has high personal and professional integrity, has demonstrated exceptional ability and judgment, and is expected, in the judgment of the Board, to be highly effective, in collaboration with the other nominees to the Board, in collectively serving the interests of the Corporation and its Stockholders. In addition to the minimum qualifications set forth above, the Board seeks to select for nomination persons possessing relevant industry or technical experience and, so that the independence of the Audit Committee is maintained, persons meeting the “independence” requirements of the NASDAQ Rules and the SEC.

Identifying and Evaluating Nominees — The Board may solicit recommendations from any sources it deems appropriate. The Board will evaluate all proposed nominees in the same manner, evaluating the qualifications of any recommended candidate and conducting inquiries it deems appropriate, without discrimination on the basis

of race, religion, national origin, sexual orientation, disability or any other basis proscribed by law. In identifying and evaluating proposed nominees, the Board may consider, in addition to the minimum professional qualifications discussed above and other criteria for Board membership approved by the Board from time to time, all facts and circumstances that it deems appropriate or advisable, including, among other things, the diversity of experience, geographic representation, and backgrounds of existing Directors. Based on these considerations, the Board may nominate a Director candidate it believes will, together with the existing Directors and other nominees, best serve the interests of the Corporation and its Stockholders.

Stockholder Recommendations — The Board’s current policy is to review and consider, in accordance with the procedures described above, any candidates for Director recommended by Stockholders of the Corporation entitled to vote for the election of Directors. All Stockholder recommendations for Director candidates must be submitted to the Secretary of the Corporation at Vicor Corporation, 25 Frontage Road, Andover, MA 01810.

All Stockholder recommendations for Director candidates must include the following information:

•

the name and address of record of the Stockholder;

•

a representation that the Stockholder is a record holder of shares of capital stock of the Corporation entitled to vote in the election of Directors, or if the Stockholder is not a record holder, evidence of ownership in accordance with Rule 14a-8(b)(2) promulgated under the Exchange Act;

•

the name, age, business and residential address, educational background, current principal occupation or employment, and principal occupation or employment for the preceding five full fiscal years of the proposed Director candidate;

•

a description of the qualifications and background of the proposed Director candidate that addresses the minimum qualifications and other criteria for Board membership approved by the Board from time to time;

•

a description of all arrangements or understandings between the Stockholder and the proposed Director candidate;

•

the consent of the proposed Director candidate (1) to be named in the proxy statement relating to the Corporation’s Annual Meeting and (2) to serve as a Director if elected at such Annual Meeting; and

•

any other information regarding the proposed Director candidate required to be included in a proxy statement filed pursuant to the rules of the SEC.

Communications with the Board

If a Stockholder wishes to communicate with any Director or the Board as a whole, he or she may do so by addressing such communications to: [Name(s) of Director(s)/Board of Directors of Vicor Corporation], c/o Corporate Secretary, Vicor Corporation, 25 Frontage Road, Andover, MA 01810. All correspondence should be sent via certified U.S. mail, return receipt requested. All correspondence received by the Corporate Secretary will be forwarded by the Corporate Secretary promptly to the addressee(s).

Code of Business Conduct and Ethics

COMPENSATION DISCUSSION AND ANALYSIS

Philosophy

The primary objective of the Corporation’s compensation program is to attract, motivate, and retain highly qualified and productive employees, using a combination of cash and equity based rewards geared to incent and reward superior performance. Salaries and cash bonuses encourage effective performance relative to current plans and objectives, while stock options are utilized to attract new talent, to retain key contributors, promote longer-term focus and to more closely align the interests of employees holding such options with those of Stockholders.

The compensation of the Corporation’s executive officers reflects their success as a team in attaining key performance indicators. In addition, each executive officer’s individual performance (as described below) represents the basis for determining his or her overall compensation.

Overview of Executive Compensation and Process

Elements of compensation for executive officers include: salary, cash bonus, stock incentive awards, health, disability, life insurance and certain perquisites.

The Chief Executive Officer makes compensation recommendations to the Executive Compensation Committee with respect to the executive officers, although the Executive Compensation Committee may exercise its discretion in modifying any recommended adjustments or awards. Such executive officers are not present at the time of these deliberations. The Executive Compensation Committee approves the annual salary of Dr. Vinciarelli, Chairman of the Board, President, and Chief Executive Officer.

The amount of each element of executive compensation is determined by the Chief Executive Officer and approved by the Executive Compensation Committee. The following factors are considered in determining the amount of each executive officer’s compensation:

•

Performance against corporate and individual goals for the previous year;

•

The relative effort made and difficulties encountered by the executive officer in pursuit of these goals; and

•

Performance in the context of the overall performance of management.

The competitiveness of the Corporation’s compensation program is assessed using local and national salary survey data. The survey data enables the Chief Executive Officer and Executive Compensation Committee to benchmark the Corporation against companies of similar size, within the same industry, and/or within the same geographic region. The survey data is used as a comparison when completing the annual merit increases for executive officers and salaried employees. The Chief Executive Officer makes salary recommendations based on the salary data and evaluation of the respective merit, skills, experience and performance of each executive officer.

2011 Advisory Votes on Executive Compensation

At the Corporation’s Annual Meeting of Stockholders held on June 23, 2011, our Stockholders cast an advisory vote to approve the compensation of our named executive officers (referred to as “Say on Pay”) as disclosed in our proxy statement for that Annual Meeting. Stockholders approved the Say on Pay proposal by the affirmative vote of 99.5% of the votes cast at that Annual Meeting. The Executive Compensation Committee believes this affirms Stockholders’ support of the Corporation’s approach to executive compensation and, therefore, did not change its approach during 2012. At the 2011 Annual Meeting, our Stockholders also cast an advisory vote on the frequency of future Say on Pay votes. The frequency receiving the highest number of votes at that Annual Meeting was every three years and, in accordance with the outcome of that advisory vote, our Board determined it will next hold a Say on Pay advisory vote at the 2014 Annual Meeting.

(1)	The amounts reported under the column heading “Salary” reflect the actual amounts paid to executive officers in the respective year.

(2)

The amounts reported under the column heading “Option Awards” reflect the aggregate grant date fair value of stock option awards in each year presented. These values have been determined under the principles used to calculate the grant date fair value of equity awards for purposes of the Corporation’s financial statements. Refer to Note 3, “Stock-Based Compensation and Employee Benefit Plans,” in the Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2012, filed on March 7, 2013, for the relevant assumptions used to determine the valuation of the Corporation’s option awards.

The amounts reported in 2010 for Dr. Vinciarelli include options granted with performance-based vesting provisions tied to achievement of certain margin targets by the VI Chip Business Unit, as the Corporation determined that it is probable that the margin targets could be achieved. The amounts reported in 2010 for Messrs. Simms and Kelleher excluded options granted with performance-based vesting provisions tied to achievement of certain quarterly revenue targets by the Brick Business Unit, as the Corporation determined that it is not yet probable that the revenue targets could be achieved. Had these amounts been included, they would be as follows:


James A. Simms	$	313,160
Barry Kelleher		626,321

The amounts reported under “Option Awards” shown for Messrs. Simms and Kelleher, as well as Mr. Tuozzolo, also include options granted as compensation for their service on the Corporation’s Board of Directors.

(3)

“All Other Compensation” amounts include car allowance, gasoline allowance, supplemental health, dental and vision insurance, the taxable portion of life insurance benefits, and the Corporation’s matching 401(k) plan contribution for each employee shown. Dr. Vinciarelli’s car allowance is $10,800, while all other amounts are individually below the threshold for individual disclosure.

Base Salary

Base salaries for the Corporation’s executive officers are based on the Corporation’s operating performance relative to comparable peer companies within certain survey information. In setting base salaries for 2012, national and local executive salary survey data for executive officers with comparable qualifications, experience and responsibilities at selected peer companies was evaluated to determine an appropriate range for merit increases. Each year such merit increase data is presented to the Executive Compensation Committee and Chief Executive Officer for approval.

Bonus

Outstanding accomplishments or the achievement of certain specific goals is rewarded through discretionary cash bonus payments, determined by the Chief Executive Officer and approved by the Executive Compensation Committee. During 2012, Mr. Davies earned a discretionary cash bonus of $125,000.

Stock Option and Equity Incentive Programs

Because of the direct relationship between the value of a stock option and the market price of the Corporation’s common stock, the Board considers the granting of stock options to be an effective method of motivating executive officers to manage the Corporation in a manner consistent with the interests of the Corporation and its Stockholders.

The Executive Compensation Committee approves stock options grants to executive officers and employees. There is no set formula for the granting of discretionary option awards to individual executive officers or employees. Stock options also are granted to certain employees upon commencement of their employment. Grants to newly hired employees are effective on the first business day of the month following employment, subject to approval by the Executive Compensation Committee.

During 2012, 2011, and 2010, non-performance based options for the purchase of the Corporation’s common stock were granted under the Vicor Corporation Amended and Restated 2000 Stock Option and Incentive Plan (the “Vicor 2000 Plan”). Performance-based options for the purchase of the Corporation’s common stock were also granted under the Vicor 2000 Plan in 2010. The exercise price of stock options for the purchase of the Corporation’s common stock is generally set at the closing price of the Corporation’s common stock on The NASDAQ Stock Market, LLC (“NASDAQ”) on the effective date of the grant. In certain circumstances, the exercise price may be set at a higher level to provide for additional performance incentives. The non-performance based grants generally vest over various periods of up to five years and may be exercised for up to 10 years from the date of grant, which is the maximum contractual term. The performance-based grants vest upon the achievement of certain quarterly revenue targets by the Brick Business Unit, and may also be exercised for up to 10 years from the date of grant. As discussed in the Directors’ Compensation section, stock options are granted to all Directors, with the exception of Dr. Vinciarelli, on the date of the Annual Meeting, in accordance with the terms of the Vicor 2000 Plan.

During 2012, 2011, and 2010, non-performance based options for the purchase of VI Chip Corporation (“VI Chip”) common stock were granted under the VI Chip Corporation 2007 Stock Option and Incentive Plan, as amended (the “2007 VI Chip Plan”). Performance based options for the purchase of VI Chip common stock were also granted under the 2007 VI Chip Plan in 2010. All grants were reviewed and approved by the VI Chip Board of Directors and the Corporation’s Executive Compensation Committee. There is no set formula for the granting of discretionary option awards to individual executive officers or employees of VI Chip. The non-performance based grants have a five year vesting schedule and may be exercised for up to 10 years from the date of grant, which is the maximum contractual term. The performance-based grants vest upon the achievement of certain margin targets and may also be exercised for up to 10 years from the date of grant. Grants to new hires are effective on the first business day of the month following employment, subject to approval by the VI Chip Board of Directors and the Corporation’s Executive Compensation Committee. VI Chip stock options are granted at a price not less than the fair value of a share of VI Chip common stock on the date of grant, as determined by the VI Chip Board of Directors and the Corporation’s Executive Compensation Committee.

During 2012, 2011, and 2010, non-performance based options for the purchase of Picor Corporation (“Picor”) common stock were granted under the Picor Corporation Amended 2001 Stock Option and Incentive Plan, as amended (the “2001 Picor Plan”). All grants were reviewed and approved by the Picor Board of Directors and the Corporation’s Executive Compensation Committee. There is no set formula for the granting of discretionary option awards to individual executives or employees of Picor. These grants have a five year vesting schedule and may be exercised for up to 10 years from the date of grant, which is the maximum contractual term. Grants to new hires are effective on the first business day of the month following employment, subject to approval by the Picor Board of Directors and the Corporation’s Executive Compensation Committee. Picor stock options are granted at a price not less than the fair value of a share of Picor common stock on the date of grant, as determined by the Picor Board of Directors and the Corporation’s Executive Compensation Committee.

Equity Compensation Plan Information

The following table sets forth certain aggregated information for the Corporation as December 31, 2012 (the end of the most recently completed fiscal year), regarding equity securities underlying stock option awards made under the Vicor Corporation 1998 Stock Option and Incentive Plan (the “Vicor 1998 Plan”) and the Vicor 2000 Plan (collectively the “Vicor Plans”), the 2007 VI Chip Plan and 2001 Picor Plan. All equity compensation plans of the Corporation have been approved by its Stockholders.

Perquisites

All employees who participated in the Corporation’s 401(k) plan received up to $3,750 in matching funds in 2012. All named executive officers, with the exception of Dr. Vinciarelli, participated in the 401(k) plan and received matching funds. All employees receive the same health and insurance benefits. In general, employees pay approximately 30% of the health premium due. In addition to participating in the health plan offered to all employees, executive officers may also receive supplemental health, dental, vision, and certain long term care insurance benefits. The Corporation does not provide pension arrangements, post-retirement health coverage, or similar benefits for its executive officers or employees.

The options granted to Dr. Vinciarelli on December 31, 2010 contain performance-based vesting provisions contingent on the achievement of certain margin targets by the VI Chip Business Unit. Because the performance-based vesting provisions have not been met, the Corporation cannot determine the vest date of these options.

Post-Employment Compensation

Pension Benefits

The Corporation does not provide pension arrangements or post-retirement health coverage for executive officers or employees. Executive officers are eligible to participate in a 401(k) defined contribution plan. In any plan year, the Corporation will make a matching contribution equal to 50% of the first 3% of the participant’s compensation that has been contributed to the plan, up to a maximum matching contribution of $3,750. All executive officers, with the exception of Dr. Vinciarelli, participated in the 401(k) plan during fiscal 2012 and received matching contributions.

Nonqualified Deferred Compensation

The Corporation does not provide any nonqualified defined contribution or other deferred compensation plans.

Other Post-Employment Payments

All employees, including executive officers, are employees-at-will and, as such, do not have employment contracts with the Corporation. Stock options issued under the Vicor 2000 Plan, the 2007 VI Chip Plan, and the 2001 Picor Plan carry a change in control provision that automatically accelerates vesting and makes unvested options fully exercisable. As of December 31, 2012, the intrinsic value of unvested options held by named executive officers was as follows:


2001 Picor Plan
Named Executive Officer	Number of Unvested Options as of December 31, 2012(1)		Intrinsic Value of Unvested Options as of December 31, 2012
James Simms		120,000		7,536
Claudio Tuozzolo		797,604		50,090

(1)

Information for the 2001 Picor Plan excludes certain unvested options with exercise prices exceeding the market value of Picor’s stock as of December 31, 2012, as the intrinsic value of those unvested options as of December 31, 2012 is zero. Information for the Vicor 2000 Plan and the 2007 VI Chip Plan are excluded from the table, as all unvested options have exercise prices exceeding the market value of the Corporation’s and VI Chip’s stock, respectively, as of December 31, 2012, and, therefore, the intrinsic value of those unvested options as of December 31, 2012 is zero.

David T. Riddiford		30,000		13,738		43,738

(1)

Dr. Vinciarelli has been omitted from this table since he receives no compensation for serving on the Board. Messrs. Kelleher, Simms and Tuozzolo have been omitted from this table because, as employee Directors, they receive no cash fees in addition to their salary for serving on the Board and their stock option awards are included in the Summary Compensation Table.

(2)

These amounts reflect the aggregate grant date fair value of stock option awards granted during 2012. These values have been determined under the principles used to calculate the grant date fair value of equity awards for purposes of the Corporation’s financial statements. Refer to Note 3, “Stock-Based Compensation and Employee Benefit Plans”, in the Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2012, filed on March 7, 2013, for the relevant assumptions used to determine the valuation of option awards.

(3)	The aggregate grant date fair value and aggregate number of stock options awarded and outstanding as of December 31, 2012 was as follows:


Name	Grant Date Fair Value of Stock Options		Number of Awards Outstanding
Samuel J. Anderson	$	45,381		15,695
Jason L. Carlson		95,588		30,695
Estia J. Eichten		45,381		15,695
Liam K. Griffin		101,587		30,695
David T. Riddiford		45,381		15,695

	$	333,318		108,475

Overview of Director Compensation and Procedures

The level of compensation of non-employee Directors is reviewed on an annual basis. To determine how appropriate the current level of compensation for non-employee Directors is, the Board reviews data from a number of different sources including:

•

publicly available data describing director compensation in peer companies;

•

survey data collected by the human resources department; and

•

information obtained directly from other companies.

Non-employee Directors are compensated through a combination of cash payments and equity-based awards. Each non-employee Director receives a quarterly retainer of $7,500 for his services. Expenses incurred by non-employee Directors in attending board and committee meetings are reimbursed.

Additionally, each Director, other than any Director holding in excess of 10% of the total number of shares of the capital stock of the Corporation (i.e., Dr. Vinciarelli), receives an annual grant of non-qualified stock options following the Annual Meeting of Stockholders under the Vicor 2000 Plan. Currently, the formula to calculate the stock option award is $50,000 divided by the price of a share of common stock at the close of

market as reported on the NASDAQ on the day of the Annual Meeting of Stockholders. Accordingly, each Director, other than Dr. Vinciarelli, received non-qualified stock options to purchase up to 8,224 shares of common stock on June 21, 2012 at an exercise price of $6.08 per share. Half of these options will become exercisable one year after the grant date, while the remainder becomes exercisable after two years. These options expire three years from the grant date.

Directors who are also employees do not receive cash compensation for service on the Board.

Compensation Committee Report

The Executive Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis (the “CD&A”) required by Item 402(b) of Regulation S-K for the year ended December 31, 2012 with management. Based on the reviews and discussions referred to above, the Executive Compensation Committee recommended to the Board that the CD&A be included in the Proxy Statement for the year ended December 31, 2012, for filing with the SEC.

Compensation Committee Interlocks and Insider Participation

Messrs. Carlson, Eichten, Griffin, and Riddiford serve on the Executive Compensation Committee. Messrs. Carlson, Eichten, Griffin, and Riddiford do not serve as executive officers of the Corporation. The Board is not aware of any compensation committee interlocks or other relationships that would represent a potential conflict of interest.

Report of the Audit Committee of the Board of Directors

The Audit Committee oversees the Corporation’s financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in the Annual Report with management including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Audit Committee reviewed with the independent registered public accounting firm, which is responsible for expressing an opinion on the conformity of those audited financial statements with U.S. generally accepted accounting principles, including a discussion of the quality, not just the acceptability, of the Corporation’s accounting principles and such other matters as are required to be discussed with the Audit Committee in accordance with standards established by the Public Company Accounting Oversight Board (“PCAOB”) and generally accepted auditing standards. In particular, the Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed with them under the provision of Statement on Auditing Standards No. 61 (Codification of Statements on Auditing Standards), as amended, as adopted by the PCAOB in Rule 3200T. In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by the applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee on independence. The Audit Committee discussed with the independent registered public accounting firm the auditors’ independence from management and the Corporation and considered the compatibility of non-audit services with the auditors’ independence.

The Audit Committee discussed with the independent registered public accounting firm the overall scope and plans for the firm’s annual audit. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of their periodic examination, their evaluation of the Corporation’s internal controls over financial reporting, and the overall quality of the Corporation’s financial reporting.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board (and the Board approved) that the audited financial statements be included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2012 for filing with the SEC.

Certain Relationships and Related Transactions

Mr. Anderson, a Director of the Corporation, is the founder, Chairman of the Board, President and Chief Executive Officer (“CEO”), as well as the majority voting shareholder, of Great Wall Semiconductor Corporation (“GWS”). GWS and its subsidiary design and sell semiconductors, conduct research and development activities, develop and license patents, and litigate against those who infringe upon its patented technologies. The Corporation’s gross investment in non-voting convertible preferred stock of GWS totaled $5,000,000 as of December 31, 2012, giving the Corporation an approximately 27% ownership interest in GWS. The Corporation and GWS are parties to an intellectual property cross-licensing agreement, a license agreement and two supply agreements under which the Corporation purchases certain components from GWS. Purchases from GWS totaled approximately $2,087,000 in 2012. The Corporation owed GWS approximately $281,000 for such purchases as of December 31, 2012.

The Corporation accounts for its investment in GWS under the equity method of accounting. The Corporation has determined that, while GWS is a variable interest entity, the Corporation is not the primary beneficiary. The key factors in the Corporation’s assessment were that the CEO of GWS has: (i) the power to direct the activities of GWS that most significantly impact its economic performance, and (ii) has an obligation to absorb losses or the right to receive benefits from GWS, respectively, that could potentially be significant to GWS. There was no allocation of equity method income (loss) in 2012 as GWS incurred a net loss for the year.

The Corporation’s policy and procedures with respect to the review, approval and/or ratification of related party transactions are set forth in the Corporation’s Audit Committee Charter and, in summary, require the Audit Committee to review and approve all related party transactions required to be disclosed pursuant to SEC Regulation S-K, Item 404, and to discuss with management the business rationale for the transactions and whether appropriate disclosures have been made. The related party transactions described above were subject to this policy.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires the Corporation’s executive officers and Directors, and persons who own more than 10% of a registered class of the Corporation’s equity securities (collectively, “Insiders”), to file reports of ownership and changes in ownership with the SEC and NASDAQ. Insiders are required by SEC regulation to furnish the Corporation with copies of all Section 16(a) forms they file. To the Corporation’s knowledge, based solely on a review of copies of such reports and written representations that no other reports

were required during the fiscal year ended December 31, 2012, all transactions in the Corporation’s securities that were engaged in by Insiders, and therefore required to be disclosed pursuant to Section 16(a) of the Exchange Act, were timely reported.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee, acting under authorization of the Board, pursuant to the Audit Committee charter, and following the Corporation’s By-Laws, selected Grant Thornton LLP (“GT”) as the independent registered public accounting firm for the Corporation for the fiscal year ending December 31, 2012. A representative of GT is expected to be present at the Annual Meeting and will be provided an opportunity to make a statement. The representative is expected to be available to respond to appropriate questions.

The following table summarizes the fees for services rendered by GT for the years ended December 31, 2012 and 2011 in each of the following categories:


	2012		2011
Audit Fees	$	845,000	$	836,000
Audit Related Fees		21,000		21,000
Tax Fees		187,000		176,000

Total Fees	$	1,053,000	$	1,033,000

Audit Fees include services provided in connection with the audit of the Corporation’s consolidated financial statements (including internal control reporting under Section 404 of the Sarbanes-Oxley Act), the reviews of the Corporation’s quarterly reports on Form 10-Q, assistance with and review of documents filed with the SEC, statutory audits required internationally, and accounting consultations related to the audited financial statements and necessary to comply with generally accepted auditing standards in the U.S.

Audit-Related Fees include services provided in connection with audits of the Corporation’s employee benefit plan.

Tax Fees include services provided in connection with tax compliance, tax advice, tax planning, and assistance with tax audits.

Pursuant to the Audit Committee charter, the Audit Committee must pre-approve all auditing services and the terms thereof and non-audit services (other than non-audit services prohibited under Section 10A(g) of the Exchange Act or the applicable rules of the SEC or the PCAOB) to be provided to the Corporation by the independent registered public accounting firm; provided, however, the pre-approval requirement is waived with respect to the provision of non-audit services for the Corporation if the “de minimis” provisions of Section 10A(i)(1)(B) of the Exchange Act are satisfied. Under the charter, the authority to pre-approve non-audit services may be delegated to one or more members of the Audit Committee, who shall present all decisions to pre-approve an activity to the full Audit Committee at its first meeting following such decision. The Audit Committee approved all audit and non-audit services provided to the Corporation by GT for 2012 and 2011.
