Stock Option Plan |
|
On September 17, 2007, the Company’s Board of Directors and stockholders adopted the Company’s 2007 Incentive Stock and Awards Plan, which was subsequently amended on November 5, 2008, February 26, 2012, July 18, 2012, May 2, 2013 and September 27, 2013 (as amended, the “Plan”). As of December 31, 2014, the Plan provides for the issuance of a maximum of 5,000,000 shares of the Company’s common stock. The purpose of the Plan is to provide an incentive to attract and retain directors, officers, consultants, advisors and employees whose services are considered valuable, to encourage a sense of proprietorship and to stimulate an active interest of such persons in the Company’s development and financial success. Under the Plan, the Company is authorized to issue incentive stock options intended to qualify under Section 422 of the Internal Revenue Code, non-qualified stock options, RSUs and restricted stock. The Plan is administered by the Compensation Committee of the Company’s Board of Directors. The Company had 2,366,369 shares available for future issuances under the Plan at December 31, 2014. |

Stock Options |
|
A summary of the stock option activity under the Plan for the year ended December 31, 2014 is as follows: |
|
| | Number of shares | | | Weighted Avg. Exercise Price | | | Weighted Avg. Remaining Contractual Life | | | Aggregate Intrinsic Value | | | | | | | |
Options outstanding - January 1, 2014 | | | 1,328,790 | | | $ | 5.31 | | | | | | | | | | | | | | | |
Options granted | | | 245,886 | | | $ | 6.35 | | | | | | | | | | | | | | | |
Options exercised | | | (307,429 | ) | | $ | 3.9 | | | | | | | | | | | | | | | |
Options cancelled/forfeit | | | (238,007 | ) | | $ | 6.68 | | | | | | | | | | | | | | | |
Options outstanding - December 31, 2014 | | | 1,029,240 | | | $ | 5.74 | | | | 6.05 | | | $ | 2,351,174 | | | | | | | |
Options exercisable | | | 728,585 | | | $ | 5.25 | | | | 4.97 | | | $ | 2,080,594 | | | | | | | |
Options vested and expected to vest | | | 999,175 | | | $ | 5.7 | | | | 5.98 | | | $ | 2,319,475 | | | | | | | |
|
The aggregate intrinsic value in the table above represents the total pre-tax amount of the proceeds, net of exercise price, which would have been received by option holders if all option holders had exercised and immediately sold all options with an exercise price lower than the market price on December 31, 2014, based on the closing price of the Company’s common stock of $7.50 on that date. The aggregate intrinsic value of stock options exercised during the year ended December 31, 2014 was approximately $1,161,000. |
|
During fiscal years 2014 and 2013, the Company granted stock options to certain employees, directors and consultants. The stock options were granted with an exercise price equal to the current market price of the Company’s common stock, as reported by the securities exchange or quotation system on which the common stock was then listed or quoted, at the grant date and have contractual terms ranging from three to 10 years. Vesting terms for options granted in fiscal years 2014 and 2013 to employees, directors and consultants typically included one of the following vesting schedules: 25% or 33% of the shares subject to the option vest and become exercisable on the first anniversary of the grant date and the remaining 75% or 67%, respectively, of the shares subject to the option vest and become exercisable in equal quarterly installments thereafter over two or three years, respectively; quarterly vesting over a three year period; or monthly, quarterly or 100% vesting associated with the provision or completion of services provided under contracts with consultants. Certain option awards provide for accelerated vesting if there is a change in control (as defined in the Plan) and in the event of certain modifications to the option award agreement. |
|
The fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option pricing model. Prior to April 1, 2013, expected volatilities were based on historical volatility of the Company’s common stock and other factors. Following April 1, 2013, the expected volatility is based on the historical volatilities of the common stock of comparable publicly traded companies based on the Company’s belief that it has significantly changed its business operations and focus as of such date and as a result, it has limited relevant historical data regarding the volatility of its stock price on which to base a meaningful estimate of expected volatility. The expected term of options granted was determined in accordance with the “simplified approach” as the Company has limited, relevant, historical data on employee exercises and post-vesting employment termination behavior. The expected risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The financial statement effect of forfeitures is estimated at the time of grant and revised, if necessary, if the actual effect differs from those estimates. For option grants to employees and directors, the Company assigns a forfeiture factor of 10%. These factors could change in the future, which would affect the determination of stock-based compensation expense in future periods. Utilizing these assumptions, the fair value is determined at the date of grant. |

As of December 31, 2014, there was approximately $1,571,000 of total unrecognized compensation expense related to unvested stock options granted under the Plan. That expense is expected to be recognized over the weighted-average remaining vesting period of 2.1 years. The stock-based compensation for all stock options was $1,137,634 and $1,689,756 during the years ended December 31, 2014 and 2013, respectively. |
|
Restricted Stock Units |
|
RSU awards are granted subject to certain vesting requirements and other restrictions, including performance and market based vesting criteria. The grant-date fair value of the RSUs, which has been determined based upon the market value of the Company’s common stock on the grant date, is expensed over the vesting period of the RSUs. Unvested portions of RSUs issued to consultants are remeasured on an interim basis until vesting criteria is met. On May 2, 2013, the Board of Directors of the Company amended and restated the Plan to provide for the issuance of RSUs under the Plan. |
|
Grants During the Year Ended December 31, 2013 |
|
On May 2, 2013, the Company granted 1,250,000 RSUs to its Chief Executive Officer, Mark Baum, pursuant to the Plan. Of these RSUs, 200,000 will vest on the third anniversary of the RSU grant date, subject to continued service to the Company and the remaining 1,050,000 RSUs will vest on the third anniversary of the RSU grant date, subject to the satisfaction of certain market-based and continued service conditions (the “Baum Performance Equity Award”). The market-based vesting criteria are separated into five equal tranches and require that the Company achieve and maintain certain stock price targets ranging from $10 per share to $30 per share during the three year period following the grant date. With certain limited exceptions, Mr. Baum must be employed with the Company on the third anniversary of the grant date in order for the Baum Performance Equity Award to vest. These market-based vesting conditions are further described below: |
|
Tranche | | Number of Shares | | Target Share Price | | | | | | | | | | | | | | | | | | |
Tranche 1 | | 19.05% of the shares subject to the Baum Performance Equity Award | | $10.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 2 | | 19.05% of the shares subject to the Baum Performance Equity Award | | $15.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 3 | | 19.05% of the shares subject to the Baum Performance Equity Award | | $20.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 4 | | 19.05% of the shares subject to the Baum Performance Equity Award | | $25.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 5 | | 23.80% of the shares subject to the Baum Performance Equity Award | | $30.00 or greater | | | | | | | | | | | | | | | | | | |
|
For each respective tranche to vest the following conditions must be met: (i) the Company’s common stock must have an official closing price at or above the Target Share Price for the respective tranche (each such date, a “Trigger Date”); (ii) during the period that includes the Trigger Date and the immediately following 19 trading days (the “Measurement Period”), the arithmetic mean of the 20 closing prices of the Company’s common stock during the Measurement Period must be at or above the Target Share Price for such tranche; and (iii) with certain limited exceptions, Mr. Baum must be in continuous service with the Company through the third anniversary of the grant date. Any unvested RSUs under the Baum Performance Equity Award will be forfeited on the third anniversary of the grant date. |
|
The earning and issuance of any shares under the Baum Performance Equity Award that would exceed the number of shares available for grant and/or the applicable annual per person grant limit for performance-based restricted stock units under the Plan as of the grant date of the Baum Performance Equity Award were subject to approval by the Board of Directors and the Company’s stockholders of increases tothe number of shares available for grant and the applicable annual per person grant limit for performance-based restricted stock units under the Plan. On May 2, 2013, the Board of Directors approved an amendment to the Plan to increase the number of shares available for grant from 2,400,000 to 5,000,000 shares and the applicable annual per person grant limit from 600,000 to 1,250,000 shares and on September 27, 2013, a majority of the Company’s stockholders approved the amendment to the Plan. The 450,000 RSUs subject to the Baum Performance Equity Award that were pending such approval were granted on that date. |
|
Concurrent with the issuance of the 450,000 RSUs, Mr. Baum agreed to cancel 120,000 unvested RSUs previously granted to Mr. Baum in July 2012. As a result, the Company has treated the issuance of the 450,000 RSUs as a modification of the RSU grant made to Mr. Baum in July 2012. The total compensation cost to be recognized by the Company is equal to the original grant date fair value of the canceled RSUs plus any incremental cost calculated as the excess of the fair value of the 450,000 RSUs over the fair value of the canceled 120,000 RSUs on the modification date, which is September 27, 2013. The initial fair value of the 450,000 RSUs pursuant to the Baum Performance Equity Award granted to Mr. Baum was $189,000. No incremental cost was associated with the exchange of RSUs as the fair value prior to modification was more than after the modification. The 450,000 RSUs pursuant to the Baum Performance Equity Award were valued using a Monte Carlo Simulation with a three year life, 75% volatility and a risk free interest rate of 0.64%. |
|
The initial fair value of the 200,000 RSUs and 600,000 RSUs pursuant to the Baum Performance Equity Award granted to Mr. Baum was $3,515,090. The 600,000 RSUs pursuant to the Baum Performance Equity Award were valued using a Monte Carlo Simulation with a three year life, 75% volatility and a risk free interest rate of 0.30%. |
|
On May 24, 2013, the Company granted 100,000 RSUs to a consultant that were to vest based on the satisfaction of certain market-based conditions subject to the consultant’s continued service, among other things. These market-based vesting conditions are further described below: |
|
Tranche | | Number of Shares | | Target Share Price | | | | | | | | | | | | | | | | | | |
Tranche 1 | | 20,000 shares | | $10.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 2 | | 20,000 shares | | $15.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 3 | | 20,000 shares | | $20.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 4 | | 20,000 shares | | $25.00 or greater | | | | | | | | | | | | | | | | | | |
Tranche 5 | | 20,000 shares | | $30.00 or greater | | | | | | | | | | | | | | | | | | |
|
For each respective tranche to vest the following conditions must have been met: (i) the Company’s common stock must have had an official closing price at or above the Target Share Price for the respective tranche (each such date a “Trigger Date”); (ii) during the period that included the Trigger Date and the immediately following 19 trading days (the “Measurement Period”), the arithmetic mean of the 20 closing prices during the Measurement Period have been at or above the Target Share Price for such tranche ((i) and (ii), the “Stock Price Conditions”); and (iii) with certain limited exceptions, 50% of the RSUs subject to a tranche would vest on the quarterly anniversary of the grant date following the satisfaction of the Stock Price Conditions with respect to that tranche, subject to the consultant being in continuous service with the Company on such quarterly anniversary and the remaining 50% would vest on the second anniversary of the grant date if (a) the Stock Price Conditions had been satisfied with respect to that tranche prior to the second anniversary of the grant date and (b) the consultant was in continuous service with the Company on the second anniversary of the grant date. All unvested RSUs would be forfeited on the second anniversary of the grant date. |
|
The initial value of the 100,000 RSUs with market-based vesting conditions granted to the consultant was $288,000, and as of December 31, 2013 the remeasured fair value of those RSUs was $10,080. The 100,000 RSUs were valued using a Monte Carlo Simulation with a 2 year life (based on the grant date), 75%-85% volatility and risk free interest rates of 0.13%-0.36%. During March 2014, the Company terminated its agreement with a consultant that provided for the grant of 100,000 RSUs that had vesting criteria based on the satisfaction of certain market-based conditions subject to the consultant’s continued service, among other things. Upon termination of the agreement, all 100,000 RSUs were forfeited and deemed reconveyed to the Company. |

In June 2013, the Company granted an aggregate of 34,325 RSUs to its non-employee directors, valued at $271,854. The RSUs vest in full 13 months after the date of grant subject to the director’s continued service, but the issuance and delivery of these shares are deferred until the director resigns. In September and October 2013, two directors resigned and forfeited all such RSUs. |
|
In October 2013, the Company issued 8,947 RSUs to a former director for his service to the Company as a director, valued at $39,814.
