12. Stock Plans

In July 2002, we adopted the 2002 Stock Incentive Plan (“2002 Plan”). The 2002 Plan assumed the options which remain available for grant under our option plans previously approved by stockholders. Under the 2002 Plan and predecessor plans, a total of 7.4 million shares of our common stock were authorized for issuance to employees, officers, directors, consultants, and advisers. In August 2005, we adopted an amendment to the 2002 Stock Incentive Plan (“2002 Plan”) to (i) permit the issuance of shares of restricted stock and stock appreciation rights to participants under the 2002 Plan, and (ii) increase the number of shares issuable pursuant to grants under the 2002 Plan from 2,000,000 to 3,000,000. Options granted under the 2002 Plan and predecessor plans may either be incentive stock options within the meaning of Section 422 of the Internal Revenue Code and/or options that do not qualify as incentive stock options; however, only employees are eligible to receive incentive stock options. Options granted under the option plans generally expire no later than ten years from the date of grant, except when the grantee is a 10% shareholder, in which case the maximum term is five years from the date of grant. Options generally vest at the rate of one fourth after one year from the date of grant and the remainder ratably over the subsequent three years, although options with different vesting terms are granted from time-to-time. Generally, the exercise price of any options granted under the 2002 Plan must be at least 100% of the fair market value of our common stock on the date of grant, except when the grantee is a 10% shareholder, in which case the exercise price shall be at least 110% of the fair market value of our common stock on the date of grant. The 2002 Plan expired by its terms in July 2012. On December 31, 2012, options to purchase an aggregate of 4,280,153 shares of our common stock were outstanding under the 2002 Plan.

Commencing in 2008, non-employee directors are entitled to receive stock options including an initial grant of 10,000 options upon becoming a director, an annual grant of 20,000 options thereafter, and an annual grant of 5,000 options for each committee on which they serve.

In August 2001, we adopted the 2001 Employee Non-Qualified Stock Option Plan (“2001 NQ Plan”) pursuant to which 1,750,000 shares of common stock were authorized for issuance for option grants to employees and consultants who are not officers or directors of Titan. Options granted under the option plans generally expire no later than ten years from the date of grant. Option vesting schedule and exercise price are determined at time of grant by the board of directors. Historically, the exercise prices of options granted under the 2001 NQ Plan were 100% of the fair market value of our common stock on the date of grant. The 2001 Stock Option Plan expired by its terms in August 2011. On December 31, 2012, options to purchase an aggregate of 1,199,500 shares of our common stock were outstanding under the 2001 NQ Plan.

Our option plans allow for stock options issued as the result of a merger or consolidation of another entity, including the acquisition of minority interest of our subsidiaries, to be added to the maximum number of shares provided for in the plan (“Substitute Options”). Consequently, Substitute Options are not returned to the shares reserved under the plan when cancelled. During 2012, 2011 and 2010, the number of Substitute Options cancelled was immaterial.

Options for 6.0 million and 4.3 million shares were exercisable at December 31, 2012 and 2011, respectively. The options outstanding at December 31, 2012 have been segregated into four ranges for additional disclosure as follows (options in thousands):

In addition, Ingenex, Inc., a consolidated subsidiary, had a stock option plan under which options to purchase common stock of Ingenex could have been granted. No options have been granted under such plan since 1997.

We use the Black-Scholes-Merton option-pricing model with the following assumptions to estimate the stock-based compensation expense for the years ended December 31, 2012, 2011 and 2010:

 

                         
    Years Ended December 31,  
        2012             2011             2010      

Weighted-average risk-free interest rate

    0.91     2.3     2.3

Expected dividend payments

                 

Expected holding period (years)(1)

    5.1       5.4       4.2

    1.75       1.71       1.89  

Estimated forfeiture rates for options granted to management(3)

    23     23     23

Estimated forfeiture rates for options granted to non-management(3)

    41     41     41

 

(1) Expected holding period is based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and the expectations of future employee behavior.
(2) Weighted average volatility is based on the historical volatility of the Company’s common stock.
(3) Estimated forfeiture rates are based on historical data.

Based upon the above methodology, the weighted-average fair value of options and awards granted during the years ended December 31, 2012, 2011 and 2010 was $1.09, $1.38 and $2.24, respectively.

 

The following table summarizes the stock-based compensation expense and impact on our basic and diluted loss per share for the years ended December 31, 2012, 2011 and 2010:

No tax benefit was recognized related to stock-based compensation expense since we have incurred operating losses and we have established a full valuation allowance to offset all the potential tax benefits associated with our deferred tax assets.

During the year ended December 31, 2012 we granted 1,718,000 options to employees, directors and consultants to purchase common stock. The following table summarizes option activity for the year ended December 31, 2012:
