STOCK-BASED COMPENSATION

The Company currently has two stock-based compensation plans under which awards have been granted: (1) the 2006 Management Incentive Plan (“2006 MIP”); and (2) the 2008 Equity Incentive Plan (“2008 EIP”) (collectively, the “Plans”). The Company generally issues authorized but previously unissued shares to satisfy stock option exercises, grants of restricted stock awards and vesting of restricted stock units and settlements of 2006 MIP Performance Units.

2008 EIP Awards

During the first quarter of 2008, the Board of Directors of the Company adopted the 2008 EIP, which was approved by the shareholders at the annual meeting of the shareholders on May 29, 2008. The 2008 EIP authorizes the grant of incentive and non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units and other incentive awards. Two million shares of the Company’s common stock initially were reserved for issuance under the 2008 EIP pursuant to award grants to key employees, directors and service providers. The options granted pursuant to the 2008 EIP generally have seven year terms.

An amendment to the 2008 EIP was adopted by the Company’s Board of Directors in April 2010 and approved at the Company’s annual meeting of shareholders held on June 15, 2010. This amendment, among other things, increased the number of shares reserved for issuance under the 2008 EIP by 3,400,000 shares to a total of 5,400,000 shares and provides that restricted stock awards and other full value awards will count as 1.41 shares against the available pool of shares under the plan.

An amendment to the 2008 EIP was adopted by the Company’s Board of Directors in April 2012 and approved at the Company’s annual meeting of shareholders held on June 19, 2012. This amendment increased the number of shares reserved for issuance under the 2008 EIP by 2,200,000 shares to a total of 7,600,000 shares.

An amendment to the 2008 EIP was adopted by the Company's Board of Directors in April 2014 and approved at the Company’s annual meeting of shareholders held on June 24, 2014. This amendment increased the number of shares reserved for issuance under the 2008 EIP by 3,000,000 shares to a total of 10,600,000 shares. Any shares issued in connection with an award against this 3,000,000 share pool will count against the available pool of shares on a one-to-one basis. As of December 31, 2015, there were approximately 1.1 million shares available for future grants under the 2008 EIP.

Stock options granted under the 2008 EIP generally vest in equal annual increments over the vesting period, which typically is three years for employees and one year for directors. The following table summarizes stock option grants during the years ended December 31, 2015, 2014, and 2013:

(1)	The Company granted non-qualified stock options outside its existing stock-based compensation plans in the first nine months of 2015 to three employees in connection with the employees joining the Company.


(2)	The weighted average exercise price for these options is calculated based on an exercise price of $6.36 for the options that vest on June 27, 2015, $6.99 for the options that vest on June 27, 2016 and $7.63 for the options that vest on June 27, 2017.


(3)	The Company granted non-qualified stock options outside its existing stock-based compensation plans in the third quarter of 2014 to two executives in connection with the executives joining the Company.


(4)	The Company granted non-qualified performance-based stock options outside its existing stock-based compensation plans in the first quarter of 2013 to one employee in connection with the employee joining the Company.

Nonvested stock awards, including both restricted stock and restricted stock units, generally are nontransferable until vesting and the holders are entitled to receive dividends with respect to the nonvested shares. Prior to vesting, the grantees of restricted stock are entitled to vote the shares, but the grantees of restricted stock units are not entitled to vote the shares. Generally, nonvested stock awards vest in equal annual increments over the vesting period, which typically is three years for employees and one year for directors.

The following table summarizes nonvested stock awards granted during the years ended December 31, 2015, 2014 and 2013:

Performance-Based Restricted Stock Units

On March 30, 2015, eight executive officers of the Company were granted 1,325,000 performance-based restricted stock units (“PBUs”) under the 2008 EIP. Upon vesting, the PBUs will be settled by the issuance of Company common stock equal to 50% of the number of PBUs being settled and the payment of cash in an amount equal to 50% of the fair market value of that number of shares of common stock equal to the number of PBUs being settled. The PBUs vest and become payable based on the cumulative adjusted EBITDA that the Company (excluding the Healthcare Claims Recovery Audit business) achieves for the two-year performance period ending December 31, 2016. At the threshold performance level, 35% of the PBUs will become vested and payable; at the target performance level, 100% of the PBUs will become vested and payable; and at the maximum performance level, 200% of the PBUs will become vested and payable. If performance falls between the stated performance levels, the percentage of PBUs that shall become vested and payable will be based on straight line interpolation between such stated performance levels (although the PBUs may not become vested and payable for more than 200% of the PBUs and no PBUs shall become vested and payable if performance does not equal or exceed the threshold performance level).

On September 28, 2015, certain employees of the Company were granted 1,123,333 PBUs under the 2008 EIP. On December 14, 2015, certain employees of the Company were granted an additional 45,000 PBUs under the 2008 EIP. Upon vesting, the PBUs will be settled by the issuance of Company common stock equal to 25% of the number of PBUs being settled and the payment of cash in an amount equal to 75% of the fair market value of that number of shares of common stock equal to the number of PBUs being settled. The PBUs vest and become payable based on the cumulative adjusted EBITDA that the Company (excluding the Healthcare Claims Recovery Audit business) achieves for the two-year performance period ending December 31, 2016. At the threshold performance level, 35% of the PBUs will become vested and payable and at the target performance level, 100% of the PBUs will become vested and payable. If performance falls between the stated performance levels, the percentage of PBUs that shall become vested and payable will be based on straight line interpolation between such stated performance levels (although the PBUs may not become vested and payable for more than 100% of the PBUs and no PBUs shall become vested and payable if performance does not equal or exceed the threshold performance level).

During 2015, the PBUs were expensed at the target performance level based on management's estimates. During the fourth quarter of 2015, it was determined it was "not probable" that the threshold performance level would be achieved by the vesting period ending December 31, 2016 and the Company reversed approximately $0.8 million of expense incurred in the second quarter and $0.6 million of expense incurred in third quarter, a total of $1.4 million for the year ended December 31, 2015.

The total vest date fair value of stock awards vested during the year was $1.2 million in 2015, $2.3 million in 2014 and $4.6 million in 2013.

2006 MIP Performance Units

At the annual meeting of shareholders held on August 11, 2006, the shareholders of the Company approved a proposal granting authorization to issue up to 2.1 million shares of the Company’s common stock under the 2006 MIP. At Performance Unit settlement dates, participants were issued that number of shares of Company common stock equal to 60% of the number of Performance Units being settled, and were paid in cash an amount equal to 40% of the fair market value of that number of shares of common stock equal to the number of Performance Units being settled. Prior to 2012, Performance Units were only granted in 2006 and 2007, and the last of such units were settled in May 2011.

On June 19, 2012, seven senior officers of the Company were granted 154,264 Performance Units under the 2006 MIP, comprising all remaining available awards under the 2006 MIP. The awards had an aggregate grant date fair value of $1.2 million and vest ratably over three years. Upon vesting, the Performance Units were settled by the issuance of Company common stock equal to 60% of the number of Performance Units being settled and the payment of cash in an amount equal to 40% of the fair market value of that number of shares of common stock equal to the number of Performance Units being settled.

During the year ended December 31, 2015, an aggregate of 16,530 Performance Units were settled, which resulted in the issuance of 9,918 shares of common stock and cash payments totaling less than $0.1 million. During the year ended December 31, 2014, an aggregate of 27,546 Performance Units were settled, which resulted in the issuance of 16,526 shares of common stock and cash payments totaling $0.1 million. Since the June 19, 2012 grant date to December 31, 2014, an aggregate of 137,740 Performance Units were settled by three current executive officers and three former executive officers, and 16,524 Performance Units were forfeited by one former executive officer. Such settlements resulted in the issuance of 79,356 shares of common stock and cash payments totaling $0.3 million. As of December 31, 2015, no Performance Units were outstanding. There was no settlement of Performance Units during 2012.

We recognized compensation expense of less than $0.1 million in 2015, $0.2 million in 2014 and less than $0.5 million in 2013 related to these 2006 MIP Performance Unit awards. We determined the amount of compensation expense recognized on the assumption that none of the Performance Unit awards would be forfeited and recorded actual forfeitures as incurred.

Stock-based compensation charges aggregated $3.9 million in 2015 and $4.5 million in 2014 and $6.3 million in 2013. We include these charges in “Selling, general and administrative expenses” in the accompanying Consolidated Statements of Operations. At December 31, 2015, there was $1.9 million of unrecognized stock-based compensation expense related to stock options, restricted stock awards, restricted stock unit awards, and Performance Unit awards which we expect to recognize over a weighted-average period of 2.0 years.
