STOCKHOLDERS' EQUITY

11.   STOCKHOLDERS' EQUITY

Earnings Per Share - Basic net earnings per common share is computed using the weighted average of common shares outstanding during the year. Diluted net earnings per common share reflects the potential dilution from assumed conversion of all dilutive securities such as stock options and unvested restricted stock using the treasury stock method. When the effects of the outstanding stock options are anti-dilutive, they are not included in the calculation of diluted earnings per common share. For the years ended December 31, 2013, 2012 and 2011, securities totaling approximately 0.1, 0.3, and 0.5 million shares, respectively, were excluded from the determination of diluted earnings per common share because the effect would have been anti-dilutive.

The following table sets forth the computation of basic and diluted net earnings per share for the years ended December 31, 2013, 2012 and 2011:

	Year Ended December 31,

Long Term Incentive Plan - The Company has a Long Term Incentive Plan under which the Company’s Compensation Committee may grant stock options, stock appreciation rights, restricted stock, restricted stock units or other forms of equity based or equity related awards.

During 2013, 2012 and 2011, the Company granted restricted stock to certain members of the Company’s Board of Directors and management. Restricted stock grants vest over four years and are granted at the discretion of the Compensation Committee of the Board of Directors. Certain awards also vest upon attainment of performance goals. Compensation cost is recorded on a straight-line basis over the vesting term of the shares based on the grant date value using the closing trading price. Share based compensation of $23.0, $23.4 and $25.1 was recorded during 2013, 2012, and 2011 respectively. Unrecognized compensation cost related to these grants was $53.6, $50.4, and $49.8 at December 31, 2013, 2012, and 2011, respectively.
