Stock-Based Compensation Plans

12.    Stock-Based Compensation Plans

Total compensation expense recorded during the years ended December 31, 2012, 2011 and 2010 for share-based payment awards was $0.3 million, $0.3 million and $0.8 million, respectively, of which $0.1 million, $0.06 million and $0.1 million is recorded in research and development and $0.2 million, $0.2 million and $0.7 million is recorded in general and administrative expenses in the statement of operations. At December 31, 2012, total unrecognized estimated compensation expense related to non-vested stock options granted prior to that date was approximately $0.3 million, which is expected to be recognized over a weighted-average period of 2.0 years. No tax benefit was realized due to a continued pattern of operating losses. We have a policy of issuing new shares to satisfy share option exercises. No options were exercised during the year ended December 31, 2012 and ten thousand options were exercised during the year ended December 31, 2011. Cash received from options exercised totaled $6 thousand for the year ended December 31, 2011.

During the year ended December 31, 2012, the Company granted 2,736,750 options which included 2,000,000 to Alan Rubino, 45,000 options to Michael Garone, 30,000 options to Gary Riley, 215,000 options to Timothy Rothwell, 90,000 options each to Timothy McInerney and Jacob Plotsker and 40,000 options each to Dr. Mark Rachesky, Dr. Michael Weiser, and John Harkey.

 

Using the Black-Scholes model, we have estimated our stock price volatility using the historical volatility in the market price of our common stock for the expected term of the option. The risk-free interest rate is based on the yield curve of U.S. Treasury STRIP securities for the expected term of the option. We have never paid cash dividends and do not intend to pay cash dividends in the foreseeable future. Accordingly, we assumed a 0% dividend yield. The forfeiture rate is estimated using historical option cancellation information, adjusted for anticipated changes in expected exercise and employment termination behavior. Forfeiture rates and the expected term of options are estimated separately for groups of employees that have similar historical exercise behavior. The ranges presented below are the result of certain groups of employees displaying different behavior.

The following weighted-average assumptions were used for grants made under the stock option plans for the years ended December 31, 2012, 2011 and 2010:

Stock Option Plans.    On April 20, 2007, the stockholders approved the 2007 Stock Award and Incentive Plan (the “2007 Plan”). The 2007 Plan provides for grants of options, stock appreciation rights, restricted stock, deferred stock, bonus stock and awards in lieu of obligations, dividend equivalents, other stock based awards and performance awards to executive officers and other employees of the Company, and non-employee directors, consultants and others who provide substantial service to us. The 2007 Plan provides for the issuance of 3,275,334 shares as follows: 2,500,000 new shares, 374,264 shares remaining and transferred from the Company’s 2000 Stock Option Plan (the “2000 Plan”) (which was then replaced by the 2007 Plan) and 401,070 shares remaining and transferred from the Company’s Stock Option Plan for Outside Directors (the “Directors Stock Plan”). In addition, shares cancelled, expired, forfeited, settled in cash, settled by delivery of fewer shares than the number underlying the award, or otherwise terminated under the 2000 Plan will become available for issuance under the 2007 Plan, once registered. As of December 31, 2012 189,878 shares remain available for issuance under the 2007 Plan. Generally, the options vest at the rate of 20% per year and expire within a five-to-ten-year period, as determined by the compensation committee of the Board of Directors and as defined by the Plans.

 

The Company’s other active Stock Option Plan is the 2002 Broad Based Plan (the “2002 Plan”). Under the 2002 Plan, a maximum of 160,000 shares are authorized for issuance to employees in the form of either incentive stock options (“ISOs”), as defined by the Internal Revenue Code, or non-qualified stock options, which do not qualify as ISOs. As of December 31, 2012, 160,000 shares remain available for issuance under the 2002 Plan.

The Company also has grants outstanding under its expired and terminated 2000 Stock Option Plan (the “2000 Plan”). Under our 2000 Plan a maximum of 1,945,236 shares of our common stock were available for issuance. The 2000 Plan was available to employees, directors and consultants. The 2000 Plan provides for the grant of either ISOs, as defined by the Internal Revenue Code, or non-qualified stock options, which do not qualify as ISOs. Generally, the options vest at the rate of 20% per year and expire within a five- to ten-year period, as determined by the compensation committee of the Board of Directors and as defined by the Plans.

Transactions involving stock options awarded under the Plans described above during the years ended December 31, 2012, 2011 and 2010 are summarized as follows:

Outside Directors’ Plan.    We previously issued options to outside directors who are neither officers nor employees of Emisphere nor holders of more than 5% of our common stock under the Directors Stock Plan. As amended, a maximum of 725,000 shares of our common stock were available for issuance under the Outside Directors’ Plan in the form of options and restricted stock. The Directors Stock Plan expired on January 29, 2007. Options and restricted stock are now granted to directors under the 2007 Plan discussed above.

Directors’ Deferred Compensation Stock Plan.    The Directors’ Deferred Compensation Stock Plan (the “Directors’ Deferred Plan”) ceased as of May 2004. Under the Director’s Deferred Plan, directors who were neither officers nor employees of Emisphere had the option to elect to receive one half of the annual Board of Directors’ retainer compensation, paid for services as a Director, in deferred common stock. An aggregate of 25,000 shares of our common stock has been reserved for issuance under the Directors’ Deferred Plan. During the years ended December 31, 2004 and 2003, the outside directors earned the rights to receive an aggregate of 1,775 shares and 2,144 shares, respectively. Under the terms of the Directors’ Deferred Plan, shares are to be issued to a director within six months after he or she ceases to serve on the Board of Directors. We recorded as an expense the fair market value of the common stock issuable under the plan. As of December 31, 2012, there are no shares issuable under this plan. No grants were awarded in 2012, 2011 and 2010, and none were outstanding as of December 31, 2012.

Non-Plan Options.    Our Board of Directors has granted options (“Non-Plan Options”), which are currently outstanding for the accounts of two consultants. The Board of Directors determines the number and terms of each grant (option exercise price, vesting, and expiration date).
