Stock-Based Compensation and Employee Benefit Plans | 3. STOCK-BASED COMPENSATION AND EMPLOYEE BENEFIT PLANS Vicor currently grants stock options under the following equity compensation plans that are shareholder-approved: Amended and Restated 2000 Stock Option and Incentive Plan (the “ Vicor 2000 Plan”) — Under the Vicor 2000 Plan, the Board of Directors or the Compensation Committee of the Board of Directors may grant stock incentive awards based on the Company’s Common Stock, including stock options, stock appreciation rights, restricted stock, performance shares, unrestricted stock, deferred stock and dividend equivalent rights. Awards may be granted to employees and other key persons, including non-employee directors. Incentive stock options may be granted to employees at a price at least equal to the fair market value per share of the Common Stock on the date of grant, and non-qualified options may be granted to non-employee directors at a price at least equal to 85% of the fair market value of the Common Stock on the date of grant. A total of 4,000,000 shares of Common Stock have been reserved for issuance under the Vicor 2000 Plan. The period of time during which an option may be exercised and the vesting periods are determined by the Compensation Committee. The term of each option may not exceed ten years from the date of grant. 1998 Stock Option and Incentive Plan (the “Vicor 1998 Plan”) — The Vicor 1998 Plan permitted the grant of share options to its employees and other key persons, including non-employee directors for the purchase of up to 2,000,000 shares of common stock. As a result of the approval of the Vicor 2000 Plan, no further grants were made under the Vicor 1998 Plan. Picor Corporation (“Picor”), a privately held majority-owned subsidiary of Vicor, currently grants stock options under the following equity compensation plan that has been approved by its Board of Directors: 2001 Stock Option and Incentive Plan, as amended (the “2001 Picor Plan”) — Under the 2001 Picor Plan, the Board of Directors of Picor may grant stock incentive awards based on the Picor Common Stock, including stock options, restricted stock or unrestricted stock. Awards may be granted to employees and other key persons, including non-employee directors and full or part-time officers. Incentive stock options may be granted to employees at a price at least equal to the fair market value per share of the Picor Common Stock, based on judgments made by the Company, on the date of grant. A total of 20,000,000 shares of Picor Common Stock have been reserved for issuance under the 2001 Picor Plan. The period of time during which an option may be exercised and the vesting periods are determined by the Picor Board of Directors. The term of each option may not exceed ten years from the date of grant. VI Chip Corporation (“VI Chip”), a privately held majority-owned subsidiary of Vicor, currently grants stock options under the following equity compensation plan that has been approved by its Board of Directors: 2007 Stock Option and Incentive Plan, as amended (the “2007 VI Chip Plan”) — Under the 2007 VI Chip Plan, the Board of Directors of VI Chip may grant stock incentive awards based on the VI Chip Common Stock, including stock options, restricted stock or unrestricted stock. Awards may be granted to employees and other key persons, including non-employee directors and full or part-time officers. Incentive stock options may be granted to employees at a price at least equal to the fair market value per share of the VI Chip Common Stock, based on judgments made by the Company, on the date of grant. A total of 12,000,000 shares of VI Chip Common Stock have been reserved for issuance under the 2007 VI Chip Plan. The period of time during which an option may be exercised and the vesting periods are determined by the VI Chip Board of Directors. The term of each option may not exceed ten years from the date of grant. All non performance-based option awards are granted at an exercise price equal to or greater than the market price for Vicor at the date of the grant, and are granted at a price equal to or greater than the estimated fair value for both Picor and VI Chip based on a discounted cash flow model, at the date of grant. Options generally vest over various periods of up to six years and may be exercised for up to 10 years from the date of grant, which is the maximum contractual term. The Company uses both the graded attribution and straight-line method to recognize expense for stock-based awards. On May 17, 2013, the Company commenced an offer (the “Exchange Offer”) to its employees and directors to exchange certain outstanding options to purchase shares of the Company’s common stock granted under the Company’s Amended and Restated 2000 Stock Option and Incentive Plan, as amended (the “2000 Plan”), on a one-for-one basis, for replacement options to purchase shares of common stock, to be granted under the Company’s 2000 Plan (the “Option Exchange”). All outstanding options under the 2000 Plan granted to employees and directors prior to January 1, 2013, whether or not vested, were eligible for the Option Exchange (“Eligible Options”). Eligible Options included those options with time-based vesting provisions (“Time-Based Eligible Options”) and those options with performance-based vesting provisions tied to the achievement of certain quarterly revenue targets by the Company’s Brick Business Unit (“Performance-Based Eligible Options”). Options for the purchase of shares of common stock of the Company’s subsidiaries, VI Chip Corporation and Picor Corporation, were not eligible for the Option Exchange. Pursuant to the Exchange Offer, which expired June 17, 2013 (the “Offer Expiration Date”), 638 eligible participants tendered, and the Company accepted for exchange, options to purchase an aggregate of 1,531,077 shares of the Company’s common stock, representing approximately 91% of Eligible Options. Upon acceptance, the tendered options were cancelled, and the Company granted an equivalent number of new options (the “Replacement Options”) under the 2000 Plan. All Replacement Options vest over five years, have a 10 year term, and have terms substantially similar to other time-based vesting options awarded under the 2000 Plan. Replacement Options granted in exchange for Time-Based Eligible Options have an exercise price equal to $6.29 (being 120% of the last reported sale price per share of the Company’s common stock on the NASDAQ on the Offer Expiration Date). Replacement Options granted in exchange for Performance-Based Eligible Options have an exercise price equal to (i) $6.29 (being 120% of the last reported sale price per share of the Company’s common stock on the NASDAQ on the Offer Expiration Date) with respect to Replacement Options that vest on or prior to the first anniversary of the Offer Expiration Date; (ii) $7.34 (being 140% of the last reported sale price per share of the Company’s common stock on the NASDAQ on the Offer Expiration Date) with respect to Replacement Options that vest after the first anniversary of the Offer Expiration Date but on or prior to the second anniversary of the Offer Expiration Date; (iii) $8.38 (being 160% of the last reported sale price per share of the Company’s common stock on the NASDAQ on the Offer Expiration Date) with respect to Replacement Options that vest after the second anniversary of the Offer Expiration Date but on or prior to the third anniversary of the Offer Expiration Date; (iv) $9.43 (being 180% of the last reported sale price per share of the Company’s common stock on the NASDAQ on the Offer Expiration Date) with respect to Replacement Options that vest after the third anniversary of the Offer Expiration Date but on or prior to the fourth anniversary of the Offer Expiration Date; and (v) $10.48 (being 200% of the last reported sale price per share of the Company’s common stock on the NASDAQ on the Offer Expiration Date) with respect to Replacement Options that vest after the fourth anniversary of the Offer Expiration Date. For financial reporting purposes, the exchange of Time-Based Eligible Options for Replacement Options was considered a modification of both the exercise price and the vesting terms of the cancelled options. The accounting for these modifications resulted in total incremental expense of approximately $365,000, which, combined with the remaining unrecognized expense from the original grant date value of approximately $318,000, will be recognized over the associated service period (i.e., the five year vesting period) for each new vesting tranche. Because the Company had not previously recorded stock-based compensation expense for the Performance-Based Eligible Options, as the Company determined it was not probable the Brick Business Unit would meet the revenue targets required to trigger vesting of such options, the exchange of Replacement Options for Performance-Based Eligible Options has been accounted for as the grant of new options as of June 17, 2013, the Offer Expiration Date. As referenced above, because these Replacement Options have five different exercise prices (i.e., an increasing exercise price for each of the five different vesting periods, each with a different term to expiration), the value of such Replacement Options, calculated using the Black-Scholes methodology, was based on the assumption each vesting tranche represented a distinct instrument. The resulting total expense of approximately $2,300,000 will be recognized over the associated service period for each vesting tranche, as if the grant were, in substance, five grants of distinct instruments with different exercise prices and different, sequentially shorter, terms to expiration. The unrecognized compensation expense for these Replacement Options was approximately $1,765,000 as of December 31, 2013. Under the retirement provisions of the 2000 Plan and the option agreements applicable to the Replacement Options, the Company records all stock-based compensation expense for an option grant by the earlier of (a) the end of the associated service period (i.e., the vesting period) or (b) by age 62.5 of the employee or director to whom the options were awarded. Because of the age of certain recipient employees and directors, a number of Replacement Options granted were subject to immediate recognition of the associated total stock-based compensation expense. Accordingly, as a result of the Option Exchange, the Company recorded stock-based compensation expense during the second quarter of 2013 of approximately $625,000, of which approximately $450,000 was the result of immediate expense recognition due to the age of the recipient employee or director. Separate from the Option Exchange, on May 14, 2013, the Company awarded options to purchase, at an exercise price of $5.35 per share, an aggregate of 150,000 shares of common stock, under the 2000 Plan, to certain officers. In addition, on June 21, 2013, the Company awarded options to purchase, at an exercise price of $5.67 per share, an aggregate of 70,552 shares of common stock, under the 2000 Plan, to directors as a component of their annual compensation. The total stock-based compensation expense recognized during the second quarter of 2013 for these awards was approximately $208,000, of which approximately $190,000 was the result of immediate expense recognition due to the age of the recipient officer or director. During the third quarter of 2010, the Company granted an aggregate of 1,243,750 Performance-Based Eligible Options. Based on the final results of the Option Exchange, a total of 66,000 of these Performance-Based Eligible Options remain outstanding as of December 31, 2013. 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 remaining stock options over the relevant performance period. As of December 31, 2013, the Company determined it was not probable the revenue targets would 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 $413,000 as of December 31, 2013. On December 31, 2010, the Company granted 2,984,250 non-qualified stock options under the VI Chip 2007 Stock Option and Incentive Plan with performance-based vesting provisions tied to achievement of certain margin targets by the VI Chip subsidiary. As of December 31, 2010, the Company determined it was probable the margin targets would be achieved and, accordingly, began recording stock-based compensation expense relating to these options beginning January 1, 2011. This determination remains the same as of December 31, 2013 and, accordingly, expense has been recorded through that date. The unrecognized compensation expense for these performance-based options was approximately $727,000 as of December 31, 2013. Stock-based compensation expense for the years ended December 31 was as follows (in thousands):
|  | 2013 |  |  | 2012 |  |  | 2011 |
Cost of revenues |  | $ | 163 |  |  | $ | 45 |  |  | $ | 68 |
Selling, general and administrative |  |  | 1,942 |  |  |  | 864 |  |  |  | 1,188 |
Research and development |  |  | 345 |  |  |  | 335 |  |  |  | 667 |
Total stock based compensation |  | $ | 2,450 |  |  | $ | 1,244 |  |  | $ | 1,923 |
The increase in stock-based compensation expense in 2013 compared to 2012 was primarily due to the Option Exchange, described above. During 2013, 2012, and 2011, the Picor Board of Directors (the “Picor Board”) authorized different alternatives of net settlement to holders of Picor stock options in the tenth and final year of their respective terms. In addition, during the third quarter of 2011, the Picor Board approved an offer to repurchase up to 1,142,000 shares of Picor Common Stock from a limited number of holders who purchased these shares via exercise before October 31, 2011. As a result, the Company accrued $368,000 in the third quarter of 2011, representing the maximum repurchase obligation to these holders assuming all holders sold their shares. This resulted in additional stock-based compensation expense of $169,000 and $132,000 in Selling, general and administrative and Research and development expense, respectively, along with a charge of $67,000 against Additional paid-in-capital, in the third quarter of 2011. During the fourth quarter of 2011, the Company accounted for those options for which repurchase was ultimately not elected by the holder, reducing the accrual by $106,000, with the offset to Picor’s additional paid-in capital. The fair value for the options was estimated at the date of grant using a Black-Scholes option pricing model under all methods with the following weighted-average assumptions:
|  | Non Performance- based Stock Options |

Risk-free interest rate |  |  | 1.2 | % |  |  | 0.7 | % |  |  | 1.8 | %

Risk-free interest rate: Vicor — The Company uses the yield on zero-coupon U.S. Treasury “Strip” securities for a period that is commensurate with the expected term assumption for each vesting period. Picor and VI Chip — Picor and VI Chip use the yield to maturity of a seven-year U.S. Treasury bond, as it most closely aligns to the expected exercise period. Expected dividend yield: Vicor — The Company determines the expected dividend yield by annualizing the most recent prior cash dividends declared by the Company’s Board of Directors and dividing that result by the closing stock price on the date of that dividend declaration. Dividends are not paid on options. Picor and VI Chip — Picor and VI Chip have not and do not expect to declare and pay dividends in the foreseeable future. Therefore, the expected dividend yield is not applicable. Expected volatility: Vicor — Vicor uses historical volatility to estimate the grant-date fair value of the options, using the expected term for the period over which to calculate the volatility (see below). The Company does not expect its future volatility to differ from its historical volatility. The computation of the Company’s volatility is based on a simple average calculation of monthly volatilities over the expected term. Picor — As Picor is a nonpublic entity, historical volatility information is not available. An industry sector index of six publicly traded fabless semiconductor firms was developed for calculating historical volatility for Picor. Historical prices for each of the companies in the index based on the market price of the shares on each day of trading over the expected term were used to determine the historical volatility. VI Chip — As VI Chip is a nonpublic entity, historical volatility information is not available. An industry sector index of eleven publicly traded fabless semiconductor firms was developed for calculating historical volatility for VI Chip. Historical prices for each of the companies in the index based on the market price of the shares on each day of trading over the expected term were used to determine the historical volatility. Expected term: Vicor — The Company uses historical employee exercise and option expiration data to estimate the expected term assumption for the Black-Scholes grant-date valuation. The Company believes that this historical data is currently the best estimate of the expected term of options, and that generally all groups of the Company’s employees exhibit similar exercise behavior. Picor and VI Chip — Due to the lack of historical information, the “simplified” method as prescribed by the Securities and Exchange Commission was used to determine the expected term on grant awards that meet the definition of “plain vanilla”. For options that did not meet the criteria of “plain vanilla”, the Company calculated the expected term based on its best estimate of what the expected term would be. Forfeiture rate: The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. The forfeiture analysis is re-evaluated quarterly and the forfeiture rate is adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that vest. Vicor — The Company currently expects that for Vicor options, based on an analysis of its historical forfeitures, that approximately 78% of its options will actually vest, and therefore has applied an annual forfeiture rate of 8.0% to all unvested options as of December 31, 2013. For 2012, the Company expected 76% of its options would actually vest and applied an annual forfeiture rate of 9.00%. Picor — The Company currently expects that for Picor options, based on an analysis of its historical forfeitures, that approximately 92% of its options will actually vest, and therefore has applied an annual forfeiture rate of 2.75% to all unvested options as of December 31, 2013. For 2012, the Company expected 92% of its options would actually vest and applied an annual forfeiture rate of 2.75%. VI Chip — The Company currently expects that for VI Chip options, based on an analysis of its historical forfeitures, that approximately 80% of its options will actually vest, and therefore has applied an annual forfeiture rate of 7.0% to all unvested options as of December 31, 2013. For 2012, the Company expected 81% of its options would actually vest and applied an annual forfeiture rate of 7.00%.
