Stock Option Plans and Share-Based Compensation [Abstract] |
Stock Option Plans and Share-Based Compensation | Stock Option Plans and Share-Based Compensation Stock Option Plans Description of Share-Based Plans Equity Incentive Plan On May 19, 2009, at our 2009 Annual Meeting of Stockholders (the "2009 Annual Meeting") our stockholders approved the Omnicell, Inc. 2009 Equity Incentive Plan (the "2009 Plan") which authorized 2,100,000 shares to be issued. The 2009 Plan provides for the issuance of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards and other stock awards to our employees, directors and consultants. The 2009 Plan succeeded the 1999 Equity Incentive Plan, as amended, the 2003 Equity Incentive Plan, as amended, and the 2004 Equity Incentive Plan (collectively, the "Prior Plans"). No additional awards will be granted under any of the Prior Plans; however, all outstanding stock awards granted under the Prior Plans continue to be subject to the terms and conditions as set forth in the agreements evidencing such stock awards. For purposes of determining future common shares available for grant, for each share granted as a full-value award, including restricted stock and restricted stock units ("RSUs") performance stock awards, the shares available for grant were reduced by 1.4 shares. Equity awards granted as stock options and stock appreciation rights reduce the shares available for grant by one share. On December 16, 2010, at a Special Meeting of Stockholders, our stockholders approved an amendment to increase the number of shares of common stock authorized for issuance under the 2009 Plan by 2,600,000 shares and to provide that the number of common stock shares available for issuance under the 2009 Plan be reduced by 1.8 shares for each share granted as a full-value award granted on and after October 1, 2010. For each share granted as a full-value award granted prior to October 1, 2010, future shares available for grants under the 2009 Plan were reduced by 1.4 shares. Awards granted as stock options and stock appreciation rights continue to reduce the number of shares available for issuance under the 2009 Plan on a one-for-one basis. On May 21, 2013, at our Annual Meeting of Stockholders, our stockholders approved an amendment to increase the number of shares of common stock authorized for issuance under the 2009 Plan by 2,500,000 shares. Options granted under the 2009 Plan generally become exercisable over periods of up to 4 years , generally with one-fourth of the shares vesting one year from the vesting commencement date with respect to initial grants, and the remaining shares vesting in 36 equal monthly installments thereafter; however our board of directors may impose different vesting terms at its discretion on any award. Options under the 2009 Plan generally expire 10 years from the date of grant. We also grant both restricted stock and restricted stock units to participants under the 2009 Plan. The Board of Directors determines the award amount, the vesting provisions and the expiration period (not to exceed ten years) for each grant. Grants of restricted stock to non-employee directors are granted on the date of our annual meeting of stockholders and vest in full on the date of our next annual meeting of stockholders, provided such non-employee director remains a director on such date. The fair value of the stock on the date of issuance is amortized to expense from the date of grant to the date of vesting. RSUs granted to employees generally vest over a period of four years and are expensed ratably on a straight-line basis over the vesting period. We consider the dilutive impact of options, restricted stock and restricted stock units in our diluted net income per share calculation. The Board of Directors shall administer the 2009 Plan unless and until the Board of Directors delegates administration to a committee. Our Board of Directors has delegated administration of the 2009 Plan to the Compensation Committee of the Board of Directors and the 2009 Plan is generally administered by such committee. The Board of Directors may suspend or terminate the 2009 Plan at any time. The Board of Directors may also amend the 2009 Plan at any time or from time to time. However, no amendment will be effective unless approved by our stockholders after its adoption by our Board of Directors to the extent stockholder approval is necessary to satisfy the applicable listing requirements of NASDAQ. If we sell, lease or dispose of all or substantially all of our assets, or we are acquired pursuant to a merger or consolidation, then the surviving entity may assume or substitute all outstanding awards under the 2009 Plan. If the surviving entity does not assume or substitute these awards, then generally the stock awards will immediately and fully vest. At September 30, 2013, a total of 3,353,608 shares of common stock were reserved for future issuance under the 2009 Plan. At September 30, 2013, $6.0 million of total unrecognized compensation cost related to non-vested stock options was expected to be recognized over a weighted average period of 2.6 years. A summary of aggregate option activity for the nine months ended September 30, 2013 is presented below:
Options: |  | Number of Shares |  | Weighted- Average Exercise Price
|  | (in thousands) |  |
Outstanding at December 31, 2012 |  | 4,470 |  |  | $ | 14.06 |
Granted |  | 296 |  |  | $ | 18.10 |
Exercised |  | (1,450 | ) |  | $ | 12.59 |
Forfeited |  | (75 | ) |  | $ | 14.40 |
Expired |  | (56 | ) |  | $ | 15.68 |
Outstanding at September 30, 2013 |  | 3,185 |  |  | $ | 15.07 |
Exercisable at September 30, 2013 |  | 2,186 |  |  | $ | 14.85 |
Restricted Stock and Time-based Restricted Stock Units The non-employee members of our Board of Directors are granted restricted stock on the day of our annual meeting of stockholders and such shares of restricted stock vest on the date of the subsequent year’s annual meeting of stockholders, provided such non-employee director remains a director on such date. Restricted stock units (“RSUs”) are granted to certain of our employees and generally vest over a period of four years and are expensed ratably on a straight-line basis over the vesting period. The fair value of both restricted stock and RSUs granted pursuant to our stock option plans is the product of the number of shares granted and the grant date fair value of our common stock. Our unrecognized compensation cost related to non-vested restricted stock at September 30, 2013 was approximately $0.6 million and is expected to be recognized over a weighted-average period of 0.6 years. Expected future compensation expense relating to RSUs outstanding on September 30, 2013 is $4.8 million over a weighted-average period of 2.2 years. A summary of activity of both restricted stock and RSUs for the nine months ended September 30, 2013 is presented below:
| Restricted Stock |  | Restricted Stock Units
| Number of Shares |  | Weighted-Average Grant Date Fair Value Per Share |  | Number of Shares |  | Weighted-Average Grant Date Fair Value Per Share
| (in thousands) |  |  |  | (in thousands) |  |
Non-vested, December 31, 2012 | 58 |  |  | $ | 14.19 |  |  | 389 |  |  | $ | 14.09 |
Granted | 55 |  |  | $ | 18.20 |  |  | 125 |  |  | $ | 18.12 |
Vested | (61 | ) |  | $ | 14.23 |  |  | (98 | ) |  | $ | 13.90 |
Forfeited | — |  |  | $ | — |  |  | (21 | ) |  | $ | 14.07 |
Non-vested, September 30, 2013 | 52 |  |  | $ | 18.43 |  |  | 395 |  |  | $ | 15.41 |
Performance-Based Restricted Stock Units In 2011, we began incorporating performance-based restricted stock units ("PSUs") as an element of our executive compensation plans. For 2011, we granted 100,000 PSUs; however, pursuant to their terms, 120,000 PSUs ultimately became eligible for vesting based on the achievement of a certain level of shareholder return for 2011 as described below. In 2012, we granted 125,000 PSUs of which 62,500 became eligible for vesting based on the achievement of a certain level of stockholder return for 2012 as described below. Our unrecognized compensation cost related to non-vested performance-based restricted stock units at September 30, 2013 was approximately $1.5 million and is expected to be recognized over a weighted-average period of 1.3 years. For the three months ended September 30, 2013 and 2012, we recognized $0.4 million and $0.2 million, respectively, of compensation expense for the performance-based restricted stock units. For the nine months ended September 30, 2013 and 2012, we recognized $1.2 million and $0.8 million, respectively, of compensation expense for the performance-based restricted stock units. The accounting guidance for awards with market conditions differs from that for awards with service conditions only or service and performance conditions. Because the grant date fair value of an award containing market conditions is calculated as the expected value, averaging over all possible outcomes, the measured expense is amortized over the service period, regardless of whether the market condition is ever actually met. The fair value of a PSU award is the average of trial-specific values of the award over each of one million Monte Carlo trials. Each trial-specific value is the market value of the award at the end of the one-year performance period discounted back to the grant date. The market value of the award for each trial at the end of the performance period is the product of (a) the per share value of Omnicell stock at the end of the performance period and (b) the number of shares that vest. The number of shares that vest at the end of the performance period depends on the percentile ranking of the total stockholder return for Omnicell stock over the performance period relative to the total stockholder return of each of the other companies in the NASDAQ Healthcare Index (the "Index") as shown in the tables below. Vesting for the PSU awards is based on the percentile placement of our total stockholder return among the companies listed in the Index and time-based vesting. We calculate total stockholder return based on the one year annualized rates of return reflecting price appreciation plus reinvestment of dividends. For PSU awards granted on February 5, 2013 and on March 5, 2013, stock price appreciation is calculated based on the average closing prices of our common stock for the last 20 trading days leading to February 28, 2014. For PSU awards granted in 2011 and 2012, stock price appreciation is calculated based on the average closing prices of the applicable company's common stock for the 20 trading days ending on the last trading day of the year prior to the date of grant as compared to the average closing prices for the 20 trading days ended on the last trading day of the year of grant. The following table shows the percent of PSUs granted in 2011 and eligible for further time-based vesting based on our percentile placement:
Percentile Placement of Our Total Stockholder Return |  | % of PSUs Eligible for Time- Based Vesting
Below the 35th percentile |  | —%
At least the 35th percentile, but below the 50th percentile |  | 50%
At least the 50th percentile, but below the 65th percentile |  | 100%
At least the 65th percentile, but below the 75th percentile (1) |  | 110% to 119%
At or above the 75th percentile |  | 120%
(1) The actual percentage of PSUs eligible for further time-based vesting is based on straight-line interpolation, where, for example, if the ranking is the 70th percentile, then the vesting percentage is 115%. On January 17, 2012, the Compensation Committee of our Board of Directors confirmed 76.3% as the percentile rank of Omnicell’s 2011 total stockholder return. This resulted in 120% of the 2011 PSU awards, or 120,000 shares, becoming eligible for further time-based vesting. The eligible PSU awards will vest as follows: 25% of the eligible awards for the first year vested immediately on January 17, 2012 with the remaining eligible awards vesting in equal increments, semi-annually, over the subsequent three year period beginning on June 15th and December 15th of the year after the date of grant and each subsequent year. Vesting is contingent upon continued service. Of the 120,000 shares eligible for time-based vesting under the 2011 PSU awards, 10,000 shares vested during the year ended December 31, 2012. The following table shows the percent of PSUs granted in 2012 eligible for further time-based vesting based on our percentile placement:
Percentile Placement of Our Total Shareholder Return | % of PSUs Eligible for Time- Based Vesting
Below the 35th percentile | —%
At least the 35th percentile, but below the 50th percentile | 50%
At least the 50th percentile | 100%
On January 22, 2013, the Compensation Committee of our Board of Directors confirmed 35.3% as the percentile rank of Omnicell's 2012 total stockholder return. This resulted in 50% of the 2012 PSU awards, or 62,500 shares, as eligible for further time-based vesting. The eligible performance-based restricted stock unit awards will vest as follows: 25% of the eligible shares vested immediately on January 22, 2013 with the remaining eligible awards vesting in equal increments, semi-annually, over the subsequent three year period beginning on June 15th and December 15th of the year after the date of grant and each subsequent year. Vesting is contingent upon continued service. On February 5 and March 5 2013, the Compensation Committee approved PSU awards of 125,000 shares and 12,500 shares, respectively. If the minimum performance threshold is met as determined by the Compensation Committee of the Board of Directors in 2014, the eligible performance-based restricted stock unit awards will vest as follows: 25% of the eligible shares will vest immediately, with the remaining eligible awards vesting in equal increments, semi-annually, over the subsequent three year period beginning on June 15th and December 15th of the year after the date of grant and each subsequent year. Vesting is contingent upon continued service. A summary of activity of the PSUs for the nine months ended September 30, 2013 is presented below:
Performance-based Stock Units | Number of Units |  | Weighted- Average Grant Date Fair Value Per Unit
| (in thousands) |  |
Non-vested, December 31, 2012 | 175 |  |  | $ | 11.00 |
Granted | 140 |  |  | $ | 14.74 |
Vested | (38 | ) |  | $ | 11.02 |
Forfeited | (24 | ) |  | $ | — |
Non-vested, September 30, 2013 | 253 |  |  | $ | 13.07 |
Employee Stock Purchase Plan We have an Employee Stock Purchase Plan (“ESPP”) under which employees can purchase shares of our common stock based on a percentage of their compensation, but not greater than 15% of their earnings, up to a maximum of $25,000 of fair value per year. The purchase price per share must be equal to the lower of 85% of the fair value of the common stock at the beginning of a 24-month offering period or the end of each six-month purchasing period. As of September 30, 2013, 4,233,557 shares had been issued under the ESPP. As of September 30, 2013 there were a total of 1,097,998 shares reserved for future issuance under the ESPP. For the three months and nine months ended September 30, 2013, 193,719 and 450,713 shares, respectively, of common stock were purchased under the ESPP. Share-based Compensation We account for share-based awards granted to employees and directors, including employee stock option awards, restricted stock, PSUs and RSUs issued pursuant to the 2009 Plan and employee stock purchases made under our ESPP using the estimated grant date fair value method of accounting in accordance with ASC 718, Stock Compensation. We value options and ESPP shares using the Black-Scholes-Merton option-pricing model. Restricted stock and time-based RSUs are valued at the grant date fair value of the underlying common shares. The PSUs are valued via Monte Carlo simulation, as described above. The impact on our results for share-based compensation for the three and nine months ended September 30, 2013 and 2012 was as follows (in thousands):
| Three Months Ended September 30, | Nine Months Ended September 30,
| 2013 |  | 2012 | 2013 |  | 2012
Cost of product and service revenues | $ | 325 |  |  | $ | 275 |  | $ | 955 |  |  | $ | 776 |
Research and development expenses | 405 |  |  | 232 |  | 1,019 |  |  | 686 |
Selling, general and administrative expenses | 2,080 |  |  | 1,854 |  | 6,449 |  |  | 5,319 |
