Stock-Based Compensation

The Heartland Express, Inc. 2011 Restricted Stock Award Plan (the "Plan") made available up to 0.9 million shares for the purpose of making restricted stock grants to eligible officers and employees of the Company. During December 2011, 0.4 million shares were granted to employees. These shares are service based awards beginning December 14, 2011 and 20% of the awards vest each June 1 through 2016. The first vesting period was June 1, 2012. Once vested, there are no other restrictions on the awards. Compensation expense associated with these awards is based on the market value of the Company's stock on the grant date. The Company's market closing price on December 14, 2011, grant date, was $13.57. There were no significant assumptions made in determining the fair value. Compensation expense associated with restricted stock awards is included in salaries, wages and benefits in the consolidated statements of comprehensive income. Compensation expense associated with restricted stock awards was $0.4 million and $2.0 million for the three and nine months ended September 30, 2012. There was no related compensation expense in the three and nine months ended September 30, 2011. Unrecognized compensation expense was $2.6 million at September 30, 2012. Unrecognized compensation expense will be recognized over a weighted average period of 1.8 years from the grant date of December 14, 2011 and total period of 4.5 years.
