1. Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements of Vicor Corporation (the “Company”) have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, these interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.

     In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2011, are not necessarily indicative of the results that may be expected for any other interim period or the year ending December 31, 2011. The balance sheet at December 31, 2010, presented herein has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, (File No. 0-18277) filed by the Company with the Securities and Exchange Commission.

2. Short-Term and Long-Term Investments

     The Company’s principal sources of liquidity are its existing balances of cash and cash equivalents and short-term investments, as well as cash generated from operations. Consistent with the Company’s investment policy guidelines, the Company can invest, and has historically invested, its cash balances in demand deposit accounts, money market funds and auction rate securities meeting certain quality criteria. All of the Company’s investments are subject to credit, liquidity, market, and interest rate risk.

     The Company’s long-term investments are classified as available-for-sale. Available-for-sale securities are recorded at fair value, with unrealized gains and losses, net of tax, attributable to credit loss recorded through the statement of operations and unrealized gains and losses, net of tax, attributable to other non-credit factors recorded in “Accumulated other comprehensive loss”, a component of Stockholders’ Equity. 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 securities, considering, among other factors, credit default risk probabilities and changes in credit ratings as significant inputs.

     The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, the net amount of which, along with interest and realized gains and losses, is included in “Other income (expense), net” in the Condensed Consolidated Statements of Operations. The Company periodically evaluates investments to determine if impairment is required, whether an impairment is other than temporary, and the measurement of an impairment loss. The Company considers a variety of impairment indicators such as, but not limited to, a significant deterioration in the earnings performance, credit rating, or asset quality of the investment.

     As of June 30, 2011, the Company held par value of $11,175,000 of auction rate securities. These auction rate securities consist of collateralized debt obligations, supported by pools of student loans, sponsored by state student loan agencies and corporate student loan servicing firms. The interest rates for these securities are reset at auction at regular intervals ranging from seven to 28 days. The auction rate securities held by the Company traded at par prior to February 2008 and are callable at par at the option of the issuer.

     Until February 2008, the auction rate securities market was liquid, as the investment banks conducting the periodic “Dutch auctions” by which interest rates for the securities had been established had committed their capital to support such auctions in the event of insufficient third-party investor demand. Starting the week of February 11, 2008, a substantial number of auctions failed, as demand from third-party investors weakened and the investment banks conducting the auctions chose not to commit capital to support such auctions (i.e., investment banks chose not to purchase securities themselves in order to balance supply and demand, thereby facilitating a successful auction, as they had done in the past). The consequences of a failed auction are (a) an investor must hold the specific security until the next scheduled auction (unless that investor chooses to sell the security to a third party

Notes to Condensed Consolidated Financial Statements

outside of the auction process) and (b) the interest rate on the security generally resets to an interest rate set forth in each security’s indenture.

     As of June 30, 2011, the Company held auction rate securities that had experienced failed auctions totaling $11,175,000 at par value, all of which had been purchased through and are held by a broker-dealer affiliate of Bank of America, N.A. (the “Failed Auction Securities”). As of June 30, 2011, the majority of the Failed Auction Securities held by the Company were AAA/Aaa rated by the major credit rating agencies, with all of the securities collateralized by student loans, all of which are guaranteed by the U.S. Department of Education under the Federal Family Education Loan Program. Management is not aware of any reason to believe any of the issuers of the Failed Auction Securities held by the Company are presently at risk of default. Through June 30, 2011, the Company has continued to receive interest payments on the Failed Auction Securities in accordance with the terms of their respective indentures. Management believes the Company ultimately should be able to liquidate all of its Failed Auction Securities without significant loss primarily due to the overall quality of the issues held and the collateral securing the underlying obligations. However, current conditions in the auction rate securities market have led management to conclude the recovery period for the Failed Auction Securities exceeds 12 months. As a result, the Company continued to classify the Failed Auction Securities as long-term as of June 30, 2011.

     The following is a summary of available-for-sale securities (in thousands):

						Gross				Gross				Estimated
						Unrealized				Unrealized				Fair
June 30, 2011		Cost				Gains				Losses				Value
Failed Auction Securities		$	11,175			$	—			$	1,549			$	9,626
Brokered certificates of deposit			1,630				17				—				1,647
Certificates of deposit			448				—				—				448
		$	13,253			$	17			$	1,549			$	11,721

						Gross				Gross				Estimated
						Unrealized				Unrealized				Fair
December 31, 2010		Cost				Gains				Losses				Value
Failed Auction Securities		$	19,075			$	—			$	2,856			$	16,219
Brokered certificates of deposits			1,720				30				—				1,750
Certificates of deposit			448				—				—				448
		$	21,243			$	30			$	2,856			$	18,417

     All of the Failed Auction Securities as of June 30, 2011, have been in an unrealized loss position for greater than 12 months.

     The amortized cost and estimated fair value of available-for-sale securities on June 30, 2011, by contractual maturities, are shown below (in thousands):

						Estimated
		Cost				Fair Value
Due in one year or less		$	1,258			$	1,268
Due in two to ten years			820				827
Due in ten to twenty years			—				—
Due in twenty to forty years			11,175				9,626
		$	13,253			$	11,721

     Based on the fair value measurements described in Note 3, the fair value of the Failed Auction Securities on June 30, 2011, with a par value of $11,175,000, was estimated by the Company to be approximately $9,626,000, an increase in fair value of $1,307,000, net of $7,900,000 of redemptions from December 31, 2010. The gross unrealized loss of $1,549,000 on the Failed Auction Securities consists of two types of estimated loss: an aggregate credit loss of $243,000 and an aggregate temporary impairment of $1,306,000. For the six months ended June 30, 2011, the aggregate credit loss on the Failed Auction Securities decreased by a net amount of $367,000, which was recorded in “Net impairment gains (losses) recognized in earnings” in the Condensed Consolidated Statement of Operations. 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 securities, considering credit default risk probabilities and changes in credit ratings as significant inputs, among other factors (See Note 3).

     The following table represents a roll forward of the activity related to the credit loss recognized in earnings on available-for-sale auction rate securities held by the Company for the six months ended June 30, 2011 (in thousands):

Balance at the beginning of the period		$	610
Reductions for securities sold during the period			(366	)
Reductions for the amount related to credit (gain) loss for which other-than-temporary impairment was not previously recognized			(1	)
Balance at the end of the period		$	243

     For the second quarter of 2011, the Company decreased the temporary impairment recorded in “Accumulated other comprehensive loss” in the Condensed Consolidated Balance Sheet by $815,000, of which $753,000 relates to $7,800,000, at par, in redemptions of the Company’s auctions rate securities during the second quarter and $62,000 to reflect an increase in the estimated fair value of the Failed Auction Securities.

     At this time, the Company has no intent to sell any of the impaired Failed Auction Securities and does not believe it is more likely than not the Company will be required to sell any of these securities. Management expects the securities to regain liquidity as the financial markets recover from the current economic downturn. If current market conditions deteriorate further, the Company may be required to record additional unrealized losses. If the credit rating of the security deteriorates, or the anticipated recovery in the market values does not occur, the Company may be required to adjust the carrying value of these investments through impairment charges recorded in the Condensed Consolidated Statement of Operations, and any such impairment adjustments may be material.

     Based on the Company’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 Securities held will affect the Company’s ability to execute its current operating plan.

3. Fair Value Measurements

     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.

     The Company uses the fair value option for certain financial assets, which allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for specified financial assets and liabilities on a case-by-case basis.

     Assets measured at fair value on a recurring basis include the following as of June 30, 2011 (in thousands):

		Using
						Significant
		Quoted Prices				Other				Significant
		in Active				Observable				Unobservable				Total Fair
		Markets				Inputs				Inputs				Value as of
		(Level 1)				(Level 2)				(Level 3)				June 30, 2011
Cash Equivalents:
Money market funds		$	13,973			$	—			$	—			$	13,973
Long term investments:
Auction rate securities			—				—				9,626				9,626
Brokered certificates of deposit							1,647				—				1,647
Certificate of deposit			448				—				—				448

     The Company has brokered certificates of deposit classified as Level 2 because the fair value for these investments has been determined utilizing observable inputs from non-active markets. The fair values fluctuate with changes in market interest rates obtained from information available in publicly quoted markets.

     As of June 30, 2011, there was insufficient observable auction rate security market information available to determine the fair value of the Failed Auction Securities using Level 1 or Level 2 inputs. As such, the Company’s investments in Failed Auction Securities were deemed to require valuation using Level 3 inputs. Management, after consulting with advisors, valued the Failed Auction Securities 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’s interest rate was set). Management utilized a probability weighted discounted cash flow (“DCF”) model to determine the estimated fair value of these securities as of June 30, 2011. The major assumptions used in preparing the DCF model included: estimates for the amount and timing of future interest and principal payments based on default probability assumptions used to measure the credit loss of approximately 2.5%; the rate of return required by investors to own these securities in the current environment, which management estimates to be 5.0% above the risk free rate of return; and an estimated timeframe of three to five years for successful auctions for these securities to occur. In making these assumptions, management considered relevant factors including: the formula applicable to each security defining the interest rate paid to investors in the event of a failed auction (the “Penalty Rate”); forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S. Department of Education of the underlying student loans, guarantees by other third parties, and additional credit enhancements provided through other means; and publicly available pricing data for recently issued student loan asset-backed securities not subject to auctions. In developing its estimate of the rate of return required by investors to own these securities, management compared the Penalty Rates of the Failed Auction Securities with yields of actively traded long-term bonds with similar characteristics and, reflecting the limited liquidity for auction rate securities and the discounts to par value seen in recent tender offers by issuers and arms’ length market transactions between informed buyers and

Notes to Condensed Consolidated Financial Statements

sellers, estimated the implied yield (i.e., the discount to par value) necessary to complete a sale of the Failed Auction Securities. Management has calculated an increase or decrease in the liquidity risk premium of 5.0% referenced above of 1.0% (i.e., 100 basis points) as used in the model, would decrease or increase, respectively, the fair value of the Failed Auction Securities by approximately $400,000.

     The following table summarizes the change in the estimated fair values calculated for those assets valued on a recurring basis utilizing Level 3 inputs (i.e., the Failed Auction Securities) for the six months ended June 30, 2011 (in thousands):

Balance at the beginning of the period		$	16,219
Redemptions , at par			(7,900	)
Credit gains on available for sales securities included in Other income (expense), net			367
Unrealized gain included in Other comprehensive loss			940
Balance at the end of the period		$	9,626

4.Stock Based Compensation

     The Company uses the Black-Scholes option pricing model to calculate the fair value of stock option awards as of their grant date. Stock-based compensation expense for the three and six months ended June 30 was as follows (in thousands):

		Three Months Ended								Six Months Ended
		June 30,								June 30,
		2011				2010				2011				2010
Cost of revenues		$	18			$	2			$	35			$	6
Selling, general and administrative			295				121				525				206
Research and development			142				50				279				86
Total stock based compensation		$	455			$	173			$	839			$	298

     During the third quarter of 2010, the Company granted 1,243,750 non-qualified stock options under the Vicor Corporation Amended and Restated 2000 Stock Option and Incentive Plan (the “2000 Plan”), with performance-based vesting provisions tied to achievement of certain quarterly revenue targets by the Brick Business Unit. Under the accounting rules for performance-based awards, the Company is required to assess, on an ongoing basis, the probability of whether the performance criteria will be achieved. If and when achievement is deemed probable, the Company will begin to recognize the associated compensation expense for the stock options over the relevant performance period. As of June 30, 2011, the Company determined that it was not probable the revenue targets could be achieved and, accordingly, has not recorded any compensation expense relating to these options since the grant date. The unrecognized compensation expense of these performance-based options was approximately $7,790,000 as of June 30, 2011.

     On December 31, 2010, the Company granted 2,984,250 non-qualified stock options under the 2007 V*I Chip Plan with performance-based vesting provisions tied to achievement of certain margin targets by the V*I Chip subsidiary. As of December 31, 2010, the Company determined it was probable the margin targets could be achieved and, accordingly, began recording compensation expense relating to these options beginning January 1, 2011. The unrecognized compensation expense of these performance-based options was approximately $1,338,000 as of June 30, 2011.

6. Inventories

     Inventories are valued at the lower of cost (determined using the first-in, first-out 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.

     The Company provides reserves for inventories estimated to be excess, obsolete or unmarketable. The Company’s estimation process for assessing net realizable value is based upon its known backlog, projected future demand and expected market conditions. If the Company’s estimated demand and / or market expectation were to change or if product sales were to decline, the Company’s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues.

7. Other Investments

     The Company’s gross investment in non-voting convertible preferred stock of Great Wall Semiconductor Corporation (“GWS”) totaled $5,000,000 as of June 30, 2011, and December 31, 2010, giving the Company an approximately 30% ownership interest in 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 patented technology. A director of the Company is the founder, Chairman of the Board, President and Chief Executive Officer (“CEO”), as well as the majority voting shareholder, of GWS. The Company and GWS are parties to an intellectual property cross-licensing agreement, a license agreement and two supply agreements under which the Company purchases certain components from GWS. Purchases from GWS totaled approximately $2,092,000 and $1,333,000 for the six months ended June 30, 2011, and 2010, respectively.

     The Company accounts for its investment in GWS under the equity method of accounting. The Company has determined that, while GWS is a variable interest entity, the Company is not the primary beneficiary. The key factors in the Company’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) for the six months ended June 30, 2011 and 2010, as GWS incurred a net loss in each period. The balance in the Company’s investment in GWS was zero as of June 30, 2011, and December 31, 2010.

8. Product Warranties

     The Company generally offers a two-year warranty for all of its products. The Company provides for the estimated cost of product warranties at the time product revenue is recognized. Factors that affect the Company’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 the warranty reserves and adjusts the amounts as necessary. Warranty obligations are included in “Accrued expenses” in the accompanying Condensed Consolidated Balance Sheets.

     Product warranty activity for the three and six months ended June 30, was as follows (in thousands):

		Three Months Ended								Six Months Ended
		June 30,								June 30,
		2011				2010				2011				2010
Balance at the beginning of the period		$	1,260			$	720			$	649			$	772
Accruals for warranties for products sold in the period			309				371				1,034				418
Fulfillment of warranty obligations			(281	)			(8	)			(409	)			(17	)
Revisions of estimated obligations			11				(45	)			25				(135	)
Balance at the end of the period		$	1,299			$	1,038			$	1,299			$	1,038

     The increase in Accruals for warranties for products sold for the six months ended June 30, 2011 was primarily due to additional reserves established during the first quarter of 2011 for expected future replacements of certain products under warranty that were manufactured with a component that exhibited a higher than expected failure rate.

9. Income Taxes

     In 2011 and 2010, the tax provision is based on the estimated annual effective tax rate for the year, which includes estimated federal, state and foreign income taxes on the Company’s projected annual pre-tax income and estimated federal and state income taxes for certain noncontrolling interest subsidiaries that are not part of the Company’s consolidated income tax returns, offset in 2010 by the expected utilization of federal and foreign net operating loss carryforwards. The 2011 and 2010 tax provisions also include discrete items, principally expense for increases in state taxes and accrued interest for potential liabilities.

     The provision for income taxes and the effective income tax rate for the three and six months ended June 30, were as follows (in thousands):

		Three Months Ended								Six Months Ended
		June 30,								June 30,
		2011				2010				2011				2010
Provision for income taxes		$	1,726			$	319			$	3,779			$	957
Effective income tax rate			35.0	%			6.3	%			33.9	%			12.4	%

     For the three and six months ended June 30, 2011 compared to 2010, the provision for income taxes and the effective income tax rate increased due to the complete utilization of remaining federal, foreign and a significant portion of remaining state net operating loss carryforwards through the end of 2010, which lowered the income tax provision in 2010.

     As of June 30, 2011, the Company had a remaining valuation allowance of approximately $10,400,000 against certain deferred tax assets, for which realization cannot be considered more likely than not at this time. Such deferred tax assets principally relate to tax credit carryforwards in certain state tax jurisdictions for which sufficient taxable income for utilization cannot be projected at this time or the credits may expire without being utilized. Management assesses the need for the valuation allowance on a quarterly basis. If and when management determines the valuation allowance should be released, the adjustment would result in a tax benefit in the Consolidated Statements of Operations and may include a portion to be accounted for through “Additional paid-in capital”, a component of Stockholders’ Equity. The amount of the tax benefit to be recorded in a particular quarter could be material.

     In January 2010, the Company received notice from the Commonwealth of Massachusetts that its Massachusetts corporate excise tax returns, for tax years 2006 and 2007 had been selected for audit. The Massachusetts audit was completed and settled in the second quarter of 2011 for an immaterial amount. There are no other income tax audits currently in process.

10. Comprehensive Income (Loss)

     The following table sets forth the computation of “Comprehensive income (loss)” for the three and six months ended June 30, (in thousands):

		Three Months Ended								Six Months Ended

11. Commitments and Contingencies

     At June 30, 2011, the Company had approximately $1,220,000 of capital expenditure commitments.

     On February 22, 2007, the Company announced it had reached an agreement in principle with Ericsson, Inc., the U.S. affiliate of LM Ericsson, to settle a lawsuit brought by Ericsson against the Company in California state court. Under the terms of the settlement agreement entered into on March 29, 2007, after a court ordered mediation, the Company paid $50,000,000 to Ericsson, of which $12,800,000 was reimbursed by the Company’s insurance carriers. Accordingly, the Company recorded a net loss of $37,200,000 from the litigation — related settlements in the fourth quarter of 2006. The Company has been seeking further reimbursement from its insurance carriers. On November 14, 2008, a jury in the United States District Court for the District of Massachusetts found in favor of the Company in a lawsuit against certain of its insurance carriers with respect to the Ericsson settlement. The jury awarded $17,300,000 in damages to the Company, although the verdict is subject to challenge in the trial court and on appeal. Both parties filed certain motions subsequent to the ruling and, on March 2, 2009, the judge in the case rendered his decision on the subsequent motions, reducing the jury award by $4,000,000. On March 26, 2009, the U.S. District Court, District of Massachusetts (“the Court”) issued its judgment in the matter, affirming the award of $13,300,000, plus prejudgment interest from the date of breach on March 29, 2007, through March 26, 2009, the date of judgment in the amount of approximately $3,179,000. The insurance carriers have filed their appeal to this total judgment in the amount of approximately $16,479,000. No final and collectible judgment has been entered by the Court as of June 30, 2011.

     On January 28, 2011, SynQor, Inc. (“SynQor”) filed a complaint for patent infringement against Ericsson, Inc. (“Ericsson”), Cisco Systems, Inc. (“Cisco”) and the Company in U.S. District Court for the Eastern District of Texas. This immediately followed a complaint filed by the Company on January 26, 2011, in U.S. District Court for the District of Massachusetts, in which the Company sought a declaratory judgment that its bus converter products do not infringe any valid claim of certain of SynQor’s U.S. patents, and that the claims of those patents are invalid. With respect to the Company, SynQor’s complaint alleges the Company’s products, including, but not limited to, unregulated bus converters used in intermediate bus architecture power supply

VICOR CORPORATION

Notes to Condensed Consolidated Financial Statements
June 30, 2011
(unaudited)

systems, infringe certain SynQor patents. SynQor seeks, amongst other items, an injunction against further infringement and an award of unspecified compensatory and enhanced damages, interest, costs and attorney fees. On February 8, 2011, SynQor filed a motion for preliminary injunction seeking an order enjoining the Company from manufacturing, using, selling, and offering for sale in the United States and/or importing into the United States certain identified unregulated bus converters, as well as any other bus converters not significantly different from those products. On February 17, 2011, the Company withdrew its Massachusetts action without prejudice to allow the litigation to proceed in Texas. On May 16, 2011, SynQor announced it was withdrawing its motion for preliminary injunction against the Company. The Company does not believe any of its products, including its unregulated bus converters, infringe any valid claim of the SynQor patents, either alone or when used in an intermediate bus architecture implementation. The Company believes SynQor’s claims lack merit and therefore plans to vigorously defend itself against SynQor’s patent infringement allegations.

     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 to have a material adverse impact on the Company’s financial position or results of operations.

12. Segment Information

     The Company has organized its business segments according to its key product lines. The Brick Business Unit segment (“BBU”) designs, develops, manufactures and markets the Company’s modular power converters and configurable products, and also includes the operations of the Company’s Westcor division, the six entities comprising Vicor Custom Power, and the BBU operations of Vicor Japan Company, Ltd. (“VJCL”). The V*I Chip segment includes V*I Chip Corporation, which designs, develops, manufactures and markets the Company’s factorized power architecture (“FPA”) products. The V*I Chip segment also includes the V*I Chip business conducted through VJCL. Picor Corporation designs, develops, manufactures and markets integrated circuits and related products for use in a variety of power management and power system applications. Picor develops these products to be sold as part of the Company’s products or to third parties for separate applications.

     During the fourth quarter of 2010, the Company began to include the net revenues and cost of revenues for shipments of V*I Chip products by VJCL in the V*I Chip segment, along with an allocation of certain VJCL operating expenses from the BBU to the V*I Chip segment. Previously, all VJCL operating activity had been included in the BBU segment. The segment information for the three and six months ended June 30, 2010 has been reclassified to conform to this new presentation.

     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 the Company’s facilities, real estate, and certain investments.

13. Impact of Recently Issued Accounting Standards

     The Company will be adopting new accounting guidance related to the presentation of comprehensive income beginning January 1, 2012. The new accounting guidance will allow the Company the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of

VICOR CORPORATION

Notes to Condensed Consolidated Financial Statements
June 30, 2011
(unaudited)

comprehensive income or in two separate but consecutive statements. With both choices, the Company will be required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The new accounting guidance will eliminate the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The new accounting guidance will not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. While the Company has not decided which presentation option it will select, the Company does not believe the adoption of this new guidance will have a material effect on the Company’s financial position or results of operations.

14. Subsequent Event

     On July 22, 2011, the Company’s Board of Directors approved a cash dividend of $0.15 per share of the Company’s common stock. The total dividend of approximately $6,300,000 will be paid on August 31, 2011, to shareholders of record at the close of business on August 9, 2011.

     Operating expenses for the three months ended June 30, 2011, increased $1,827,000, or 8.7%, to $22,925,000 from $21,098,000 in 2010, due to an increase in selling, general and administrative expenses of $961,000 and research and development expenses of $866,000. The primary increases in selling, general and administrative expenses were compensation expenses of $798,000, legal fees of $394,000, and outside services of $279,000, partially offset by decreases in commissions expense of $455,000 and advertising expenses of $338,000.

The primary reason for the increase was an increase in credit gain on available for sale securities of $359,000, offset by a decrease in gain on disposals of equipment of $248,000.

     Other income (expense), net for the six months ended June 30, 2011, decreased $144,000 to $348,000 from $492,000 in 2010. The primary reasons for the decrease were decreases in gain on disposals of equipment of $249,000, foreign currency losses of $182,000, and interest income of $104,000, offset by an increase in credit gain on available for sale securities of $409,000.

     For the six months ended June 30, 2011, depreciation and amortization totaled $5,401,000 and capital additions totaled $5,035,000, compared to $4,957,000 and $4,814,000, respectively, for the first six months of 2010.

     Inventories increased by approximately $688,000 or 1.9% to $36,177,000, compared to $35,489,000 at December 31, 2010. This increase was associated with an increase in BBU inventories of $1,877,000, partially offset by decreases in V*I Chip and Picor inventories of approximately $843,000 and $346,000, respectively.

Critical Accounting Policies and Estimates

     Please refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, for a complete summary of the critical accounting policies and estimates.

Three months ended June 30, 2011, compared to three months ended June 30, 2010

     Net revenues for the second quarter of June 30, 2011, were $65,402,000, an increase of $8,025,000 or 14.0%, as compared to $57,377,000 for the same period a year ago, but a decrease of 7.2% on a sequential basis from the first quarter of 2011.

     The components of revenue for the three months ending June 30, were as follows (dollars in thousands):

										Increase (decrease)
		2011				2010				$				%
BBU		$	49,066			$	51,664			$	(2,598	)			(5.0	)%
V*I Chip			14,685				4,515				10,170				225.2	%
Picor			1,651				1,198				453				37.8	%
Total		$	65,402			$	57,377			$	8,025				14.0	%

     While orders during the three months ending June 30, 2011, decreased by 16.2% compared with the first quarter of 2011, consolidated revenues increased primarily due to the growth of V*I Chip revenues. The decrease in BBU revenues was due to a decrease of Vicor Custom Power revenue of approximately $6,197,000, partially offset by an increase in BBU component revenues of approximately $3,163,000. The consolidated book to bill ratio for the three months ended June 30, 2011, was 0.85:1, as compared to 1.43:1 for the corresponding period a year ago, and 0.94:1 for the first quarter of 2011. The quarterly book-to-bill ratio has been volatile and management believes that the ratio is not always an accurate indicator of the amount or timing of future revenue.

     Gross margin for the second quarter of 2011 increased $1,570,000, or 6.1%, to $27,309,000 from $25,739,000 in the second quarter of 2010. Gross margin, as a percentage of net revenues, decreased to 41.8% from 44.9% as a percentage of net revenues. The increase in gross margin dollars was primarily due to the increase in net revenues. The decrease in gross margin percentage was primarily due to a shift in product mix to a higher proportion of lower margin V*I Chip products, along with lower volumes of higher-margin Vicor Custom Power products.

     Selling, general and administrative expenses were $13,022,000 for the quarter ended June 30, 2011, an increase of $961,000, or 8.0%, as compared to $12,061,000 for the same period in 2010. Selling, general and administrative expenses as a percentage of net revenues, decreased to 19.9% from 21.0% for the same period in 2010, primarily due to the increase in net revenues.

As a percentage of net revenues, research and development decreased to 15.1% from 15.8%, primarily due to the increase in net revenues.

     Pursuant to a settlement agreement reached with UBS AG in 2008, the Company’s then-remaining par value of $8,600,000 of auction rate securities held by UBS were purchased by UBS at par value on June 30, 2010. The unrealized gain and (loss) on the Company’s auction rate securities and associated rights for the quarter ended June 30, 2010, resulted from this sale and the termination of the associated rights. Because the Company recorded, for the quarter ended March 31, 2010, an income statement gain of $4,000, representing the net of the decrease in estimated value of the auction rate securities held by UBS and the increase in the estimated value of the associated rights, the Company recognized no net loss on the sale of the auction rate securities to UBS. The increase in credit gains on available-for-sale auction rate securities (i.e., the Company’s auction rates securities held by Bank of America) was primarily due to the redemption at par by issuers of $7,800,000 of auction rate securities during the three months ended June 30, 2011, for which credit losses had previously been recorded. The decrease in interest income for the period was due to lower average

balances on the Company’s long-term investments, lower balances on auction rate securities earning higher penalty rates, as well as a general decrease in interest rates. The Company’s exposure to market risk for fluctuations in foreign currency exchange rates relates primarily to the operations of VJCL. The functional currency of the Company’s subsidiaries in Europe and Hong Kong is the U.S. dollar.

     Income before income taxes was $4,930,000 for the second quarter of 2011,compared to $5,066,000 for the same period in 2010.

     The provision for income taxes and the effective income tax rate were as follows (dollars in thousands):

		2011				2010
Provision for income taxes		$	1,726			$	319
Effective income tax rate			35.0	%			6.3	%

     For the three months ended June 30, 2011, compared to same period in 2010, the provision for income taxes and the effective tax rate increased due to the complete utilization of remaining Federal, foreign, and a significant portion of remaining state, net operating loss carryforwards through the end of 2010, which lowered the income tax provision in 2010.

     Net income of noncontrolling interest increased $138,000 from zero for the same period in 2010. This was due to higher net income of entities in which the Company holds a noncontrolling equity interest (i.e., certain Vicor Custom Power subsidiaries).

     Basic and diluted income per share attributable to Vicor Corporation was $0.07 for the second quarter of 2011, compared to $0.11 for the second quarter of 2010.

Six months ended June 30, 2011 compared to six months ended June 30, 2010

     Net revenues for the six months of 2011 were $135,857,000, an increase of $26,771,000 or 24.5%, as compared to $109,086,000, for the same period a year ago.

     The revenue increase in 2011 in each of the three business units reflects increases in bookings over the preceding several quarters. Bookings during the six months ended June 30, 2011, increased by 2.8%, compared with the last six months of 2010. This increase was caused by increases in V*I Chip and Picor orders of 18.0%, and 81.2%, respectively, offset by a decrease in BBU orders of 2.1%. The consolidated book to bill ratio for the six months ending June 30, 2011, was 0.90:1, as compared to 1.41:1 for the corresponding period a year ago, and 0.84:1 for the last six months of 2010. The quarterly book-to-bill ratio has been volatile, and management believes the ratio is not always an accurate indicator of the amount or timing of future revenue.

Gross margin, as a percentage of net revenues, decreased to 42.5% from 45.0% as a percentage of net revenues. The increase in gross margin dollars was the result of the increase in net revenues. The decrease in gross margin percentage was primarily due to a shift in product mix to a higher proportion of lower margin V*I Chip products.

     Selling, general and administrative expenses were $27,202,000 for the six months ended June 30, 2011, an increase of $3,261,000, or 13.6%, compared to $23,941,000 for the same period in 2010.

Liquidity and Capital Resources

     At June 30, 2011, the Company had $69,779,000 in cash and cash equivalents. The ratio of current assets to current liabilities was 6.4:1 as of June 30, 2011, and 5.6:1 as of December 31, 2010. Working capital increased $18,138,000 to $123,592,000 as of June 30, 2011, from $105,454,000 as of December 31, 2010. The primary factors affecting the working capital increase were increases in cash and cash equivalents of $20,500,000, inventories of $688,000 and other current assets of $1,244,000, as well as a decrease in accounts payable of $380,000, partially offset by a decrease in accounts receivable of $4,341,000. The primary sources of cash for the six months ended June 30, 2011, were $17,098,000 from operating activities and net proceeds of $7,990,000 from the sale of investments. The primary use of cash for the six months ended June 30, 2011, was $5,035,000 for the purchase of equipment.

     As of June 30, 2011, the Company held $11,175,000 of auction rate securities at par value classified as long-term investments. Please see Note 2 of the Company’s Condensed Consolidated Financial Statements for a discussion of the securities and the Company’s accounting treatment thereof.

     In November 2000, the Board of Directors of the Company authorized the repurchase of up to $30,000,000 of the Company’s Common Stock (the “November 2000 Plan”). The November 2000 Plan authorizes the Company to make such repurchases from time to time in the open market or through privately negotiated transactions. The timing and amounts of stock repurchases are at the discretion of management based on its view of economic and financial market conditions. The Company did not repurchase shares of Common Stock during the six months ended June 30, 2011. As of June 30, 2011, the Company had approximately $8,541,000 remaining under the November 2000 Plan.

     On July 22, 2011, the Company’s Board of Directors approved a cash dividend of $0.15 per share of the Company’s common stock. The total dividend of approximately $6,300,000 will be paid on August 31, 2011 to shareholders of record at the close of business on August 9, 2011.

     The Company’s primary liquidity needs are for making continuing investments in manufacturing equipment. The Company believes cash generated from operations and the total of its cash and cash equivalents will be sufficient to fund planned operations and capital equipment purchases for the foreseeable future. The Company had approximately $1,220,000 of capital expenditure commitments, principally for manufacturing equipment, as of June 30, 2011.

     Based on the Company’s ability to access cash and cash equivalents and its expected operating cash flows, management does not anticipate the current lack of liquidity of the Company’s auction rate securities will affect the Company’s ability to execute its current operating plan.

     The Company does not consider the impact of inflation and changing prices on its business activities or fluctuations in the exchange rates for foreign currency transactions to have been significant during the last three fiscal years.

Vicor Corporation
June 30, 2011

Item 3 — Quantitative and Qualitative Disclosures About Market Risk

     The Company is exposed to a variety of market risks, including changes in interest rates affecting the return on its cash and cash equivalents and fluctuations in foreign currency exchange rates. As the Company’s cash and cash equivalents consist principally of money market securities, which are short-term in nature, the Company believes its exposure to market risk on interest rate fluctuations for these investments is not significant. The Company’s long-term investments consist mainly of municipal and corporate debt securities, of which the Failed Auction Securities represent a significant portion. While the Failed Auction Securities are all highly rated investments, generally with AAA/Aaa ratings, continued failure to sell at their reset dates could negatively impact the carrying value of the investments, in turn leading to impairment charges in future periods. Changes in the fair value of the Failed Auction Securities attributable to credit loss are recorded through earnings, with the remainder of any change recorded in “Accumulated other comprehensive loss”, a component of Stockholders’ Equity. Should a decline in the value of the Failed Auction Securities be other than temporary, the losses would be recorded in “Other income (expense), net.” The Company does not believe there was an “other-than-temporary” decline in value in these securities as of June 30, 2011.

     The Company’s exposure to market risk for fluctuations in foreign currency exchange rates relates primarily to the operations of VJCL and changes in the dollar/yen exchange rate, as the functional currency of the Company’s subsidiaries in Europe and Hong Kong is the U.S. dollar. Therefore, the Company believes market risk is mitigated since these operations are not materially exposed to foreign exchange fluctuations.

Item 4 — Controls and Procedures

(a) Disclosure regarding controls and procedures.

     As required by Rule 13a-15 under the Securities Exchange Act, the Company’s management, with the participation of the Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures, as of the end of the last fiscal quarter (i.e., June 30, 2011). The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that 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 the Company’s disclosure controls and procedures as of June 30, 2011, the Chief Executive Officer and Chief Financial Officer concluded that, as of such date, the Company’s disclosure controls and procedures were effective at the reasonable assurance level.

     A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Accordingly, management, including the CEO and CFO, recognizes the Company’s disclosure controls or its 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 that 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 that 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’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.

(b) Changes in internal control over financial reporting.

     There was no change in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended June 30, 2011, that materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
