Stock-Based Compensation |
Stock-Based Compensation | (9) Stock-Based Compensation The Company is authorized to grant up to 6,900,000 stock-based compensation awards to key executives, employees and directors of the Company under the Tutor Perini Corporation Long-Term Incentive Plan (the “Plan”). The Plan allows stock-based compensation awards to be granted in a variety of forms, including restricted stock awards and stock options. The terms and conditions of the awards granted are established by the Compensation Committee of the Company’s Board of Directors who also administers the Plan. Restricted Stock Awards Restricted stock awards generally vest subject to the satisfaction of service requirements or the satisfaction of both service requirements and achievement of certain performance targets. Upon vesting, each award is exchanged for one share of the Company’s common stock. The grant date fair values of these awards are determined based on the closing price of the Company’s stock on either the award date (if subject only to service conditions), or the date that the Compensation Committee establishes the applicable performance target (if subject to performance conditions). The related compensation expense is amortized over the applicable requisite period. As of September 30, 2013, the Compensation Committee has approved the grant of an aggregate of 5,033,333 restricted stock awards to eligible participants. In March 2013, the Compensation Committee established the 2013 pre-tax income performance targets for 178,335 restricted stock units awarded in 2009 and 2010. Additionally, 66,667 restricted stock unit awards were forfeited during the nine months ended September 30, 2013. For the three and nine months ended September 30, 2013, the Company recognized $1.5 million and $5.0 million, respectively, of compensation expense related to restricted stock awards, and such expense is included in general and administrative expenses in the Consolidated Condensed Statements of Operations. As of September 30, 2013 there was $2.7 million of unrecognized compensation cost related to the unvested restricted stock awards which, absent significant forfeitures in the future, is expected to be recognized over a weighted average period of approximately 2.1 years. A summary of restricted stock awards activity for the nine months ended September 30, 2013 is as follows:

The grant date fair values of these awards are determined based on the Black-Scholes option price model on either the award date (if subject only to service conditions) or the date that the Compensation Committee establishes the applicable performance target (if subject to performance conditions). The related compensation expense is amortized over the applicable requisite service period. The exercise price of the options is equal to the closing price of the Company’s common stock on the date the awards were approved by the Compensation Committee, and the awards expire ten years from the award date. As of September 30, 2013, the Compensation Committee has approved the award of an aggregate of 2,410,465 stock option awards to eligible participants.

As of September 30, 2013, there was $0.9 million of unrecognized compensation expense related to the outstanding options, which, absent significant forfeitures in the future, is expected to be recognized over a weighted average period of approximately 2.0 years.
