Stock-based Compensation
2009 Stock Option Plan
The Company had a share-based compensation plan (the “2009 Stock Option Plan”) under which the Company granted options to purchase shares of common stock to employees, directors, and consultants as either incentive stock options or nonqualified stock options. Incentive stock options could be granted with exercise prices not less than 100% to 110% of the fair market value of the common stock. Options granted under the plan generally vest over three to four years and expire in 10 years from the date of grant.
2014 Equity Incentive Plan
In February 2014, the Company’s board of directors adopted the 2014 Equity Incentive Plan, or the 2014 Plan, which was subsequently ratified by its stockholders and became effective on May 2, 2014 (the “Effective Date”). The 2014 Plan is the successor to and continuation of the 2009 Stock Option Plan. As of the Effective Date, no additional awards will be granted under the 2009 Stock Option Plan, but all stock awards granted under the 2009 Stock Option Plan prior to the Effective Date will remain subject to the terms of the 2009 Stock Option Plan. All awards granted on and after the Effective Date will be subject to the terms of the 2014 Plan. The 2014 Plan provides for the grant of the following awards: (i) incentive stock options, (ii) nonstatutory stock options, (iii) stock appreciation rights, (iv) restricted stock awards, (v) restricted stock unit awards, and (vi) other stock awards. Employees, directors, and consultants are eligible to receive awards.
Under the 2014 Plan, the aggregate number of shares of common stock that could be issued from and after the Effective Date (the “share reserve”) could not exceed the sum of (i) 257,352 new shares, (ii) the shares that represented the 2009 Stock Option Plan’s available reserve on the Effective Date, and (iii) any returning shares from the 2009 Stock Option Plan. Under the 2014 Plan, the share reserve will automatically increase on January 1st of each year, for a period of not more than 10 years, commencing on January 1, 2015, and ending on January 1, 2024, in an amount equal to 4.0% of the total number of shares of capital stock outstanding on December 31st of the preceding calendar year. The board of directors may act prior to January 1st of a given year to provide that there will be no increase in the share reserve or that the increase will be a lesser number of shares than would otherwise occur.
On June 18, 2014, the Company’s board of directors and compensation committee approved an amendment of the 2014 Plan, subject to stockholder approval, to increase the aggregate number of shares of the Company’s common stock that may be issued under the 2014 Plan by an additional 351,653 shares. All other material terms of the 2014 Plan remained unchanged. The Company’s stockholders approved the 2014 Plan amendment on September 11, 2014.
Pursuant to the terms of the 2014 Plan, on January 1, 2015, the Company automatically added 340,484 shares to the total number of shares of common stock available for future issuance under the 2014 Plan.
On February 25, 2015, the Company's board of directors approved an amendment of the 2014 Plan, subject to stockholder approval, to increase the aggregate number of shares of common stock that may be issued pursuant to awards under the 2014 Plan by an additional 510,726 shares. The Company's stockholders approved the 2014 Plan amendment on June 4, 2015. All other material terms of the 2014 Plan otherwise remain unchanged.
April 2015 Stock Option Grants
On April 1, 2015, the Company granted options to purchase 425,967 shares of common stock to officers and other key employees, including an award to Dr. Marco Taglietti, the Company's new Chief Executive Officer, to purchase 330,000 shares of the Company's common stock. All options granted on April 1, 2015, have a 10-year term. For Dr. Taglietti's grant, one-fourth of the shares subject to the option shall vest on the one-year anniversary of the date of grant with the remainder vesting in equal monthly installments for thirty-six months thereafter, provided Dr. Taglietti continues to provide service to the Company. For all other April 1, 2015 officer and key employee grants, the shares subject to the options vest in equal monthly installments for forty-eight months as measured from the date of grant.
As of June 30, 2015, there were 618,773 shares of common stock available for future issuance under the 2014 Plan.
Option Amendments
During the quarter ended June 30, 2015, the following events resulted in the amendment to terms of outstanding stock option awards:
The Company determined the additional compensation cost associated with the previously described modifications pursuant to applicable guidance in FASB ASC Topic 718, Compensation—Stock Compensation.The additional compensation cost was determined by calculating the difference between (a) the estimated fair value of each option award immediately prior to the modifications and (b) the estimated fair value of each option award immediately after the modifications. The fair value of each option award immediately prior to and immediately after modification was estimated using the Black-Scholes option-pricing model to determine an incremental fair value, consistent with and in accordance with the Company’s existing accounting policy for stock compensation (see Note 1). Using the Black-Scholes option-pricing model, the weighted-average incremental fair value of outstanding modified option awards was $3.54 per option share. The total additional compensation cost associated with the previously described modifications was determined to be $819, of which $466 was associated with services previously performed and, therefore, was expensed in the quarter ended June 30, 2015. The remaining additional compensation cost is associated with future service periods and will be recognized as those services are performed.
See Note 15 for certain events occurring after June 30, 2015, that resulted in additional amendments to outstanding stock option awards.
2015 Inducement Plan
On March 26, 2015, the Company's board of directors adopted the 2015 Inducement Plan, or the 2015 Plan. The 2015 Plan provides for the grant of nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other forms of equity compensation (collectively, stock awards), all of which may be granted to persons not previously employees or directors of the Company, or following a bona fide period of non-employment, as an inducement material to the individuals’ entering into employment with the Company within the meaning of NASDAQ Listing Rule 5635(c)(4). The 2015 Plan has a share reserve covering 450,000 shares of common stock. During the quarter ended June 30, 2015, the Company granted an option to purchase 125,000 shares of the Company's common stock under to the 2015 Inducement Plan. As of June 30, 2015, there were 325,000 shares of common stock available for future issuance under the 2015 Plan.
2014 Employee Stock Purchase Plan
In February 2014, the Company’s board of directors adopted the 2014 Employee Stock Purchase Plan (“ESPP”), which was subsequently ratified by the Company’s stockholders and became effective on May 2, 2014. The purpose of the ESPP is to provide means by which eligible employees of the Company and of certain designated related corporations may be given an opportunity to purchase shares of the Company’s common stock, and to seek and retain services of new and existing employees and to provide incentives for such persons to exert maximum efforts for the success of the Company. Common stock that may be issued under the ESPP will not exceed 47,794 shares, plus the number of shares of common stock that are automatically added on January 1st of each year for a period of ten years, commencing on January 1, 2015, and ending on January 1, 2024, in an amount equal to the lesser of (i) 0.8% of the total number of shares of outstanding common stock on December 31 of the preceding calendar year, and (ii) 29,411 shares of common stock. Similar to the 2014 Plan, the board of directors may act prior to January 1st of a given year to provide that there will be no increase in the share reserve or that the increase will be a lesser number of shares than would otherwise occur. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code.
In the quarterly period ended March 31, 2015, the number of shares of common stock available for issuance under the ESPP was automatically increased by 29,411 shares pursuant to the terms of the ESPP and the Company issued 15,107 shares of common stock under the ESPP. There was no activity under the ESPP during the quarterly period ended June 30, 2015. As of June 30, 2015, there were 52,050 shares of common stock available for future issuance under the ESPP.
In connection with the sale of the Services Business, each of the Company’s non-executive officer employees principally providing services to the Services Business has accepted continued employment with the buyer, Accuratus, or has been terminated by July 17, 2015, the effective date of the transaction (see Note 14). As of June 30, 2015, the Company has $59 in employee withholdings under the ESPP that it will return to employees that are no longer employed by the Company because of the sale of the Services Business. These employee withholdings are included in accrued expenses in the accompanying balance sheets.
Compensation Cost
The compensation cost that has been charged against income for stock awards under the 2009 Stock Option Plan, the 2014 Plan, the 2015 Plan, and the ESPP was $819 and $1,115 for the three and six months ended June 30, 2015, respectively, and $272 and $382 for the three and six months ended June 30, 2014, respectively.
