Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | 1 3 . Stock-Based Compensation 2013 Equity Incentive Plan The Kips Bay Medical, Inc. 2013 Equity Incentive Plan (the “2013 Plan”) was adopted by the Board of Directors in March 2013 and approved by our stockholders at our annual meeting of stockholders held on May 22, 2013. The 2013 Plan permits the granting of incentive and non-statutory stock options, restricted stock, stock appreciation rights, performance units, performance shares and other stock awards to eligible employees, directors and consultants. We grant options to purchase shares of common stock under the 2013 Plan at no less than the fair market value of the underlying common stock as of the date of grant. Options granted under the 2013 Plan have a maximum term of ten years and generally vest over one to four years for employees, at the rate of 25% of total shares underlying the option each year, and over one to three years for non-employees. Under the 2013 Plan, a total of 2,500,000 shares of common stock have been reserved for issuance. As of June 27, 2015, options to purchase 1,215,000 shares of common stock were outstanding under the 2013 Plan. 2007 Long-Term Incentive Plan The Kips Bay Medical, Inc. 2007 Long-Term Incentive Plan (the “2007 Plan”) was adopted by the Board of Directors in July 2007. In conjunction with stockholder approval of the 2013 Plan, the Board terminated the 2007 Plan, although awards outstanding under the 2007 Plan will remain outstanding in accordance with and pursuant to the terms thereof. Options granted under the 2007 Plan have terms similar to those used under the 2013 Plan. As of June 27, 2015, options to purchase an aggregate of 1,181,250 shares of our common stock and restricted stock awards for 20,000 shares of our common stock remained outstanding under the 2007 Plan. The amount of stock-based compensation recognized is based on the value of the portion of awards that are ultimately expected to vest. Guidance requires forfeitures to be 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 a surrendered option. We will re-evaluate this estimate periodically and adjust the forfeiture rate on a prospective basis as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that actually vest. Stock-based compensation expense for each of the periods presented is as follows (in thousands): Three Months Ended Six Months Ended June 27, 2015 June 28, 2014 June 27, 2015 June 28, 2014 Research and development $ 20 $ 32 $ 27 $ 69 Selling, general and administrative 17 68 54 152 Total stock-based compensation $ 37 $ 100 $ 81 $ 221 A summary of option activity for the three months ended June 27, 2015 is as follows: Shares Underlying Options Weighted Average Exercise Price Per Share Options outstanding at December 31, 2014 2,114,250 $ 1.98 Granted 540,000 0.21 Exercised — — Forfeitures (171,749 ) 0.85 Cancelled (86,251 ) 1.77 Options outstanding at June 27, 2015 2,396,250 $ 1.62 Current year grants include options to purchase an aggregate of 450,000 shares of our common stock that were granted to our officers and certain employees to compensate them, in part, for temporary decreases in their base salaries in connection with our January 2015 reorganization. Restricted Stock A wards A summary of restricted stock award activity is as follows: Number of Shares Weighted Average Fair Value Per Share Awards outstanding at December 31, 2014 62,500 $ 3.67 Granted — — Vested 42,500 4.81 Cancelled — — Awards outstanding at June 27, 2015 20,000 $ 1.23 The fair value of each restricted stock award is equal to the fair market value of our common stock at the date of grant. Restricted stock awards vest over a period of time that varies with the purpose of the individual award. As of June 27, 2015, outstanding awards vest over a period of three years. The estimated fair value of restricted stock awards, including the effect of estimated forfeitures, is recognized on a straight-line basis over the restricted stock’s vesting period. We recorded stock-based compensation expense for restricted stock grants of $34,000 and $102,000 for the six months ended June 27, 2015 and June 28, 2014, respectively. Other Stock-Based Payments In conjunction with the completion of our public offering in January 2014, we issued to the underwriter and its designees warrants to purchase an aggregate of 262,500 shares of our common stock at an exercise price of $0.875 per share, or 125% of the purchase price of shares sold in the public offering. These warrants have a five-year term and became exercisable on January 23, 2015, one year after the effective date of the public offering. These warrants were not issued under the 2013 Plan.
