Stock-Based Compensation Plans

Stock-Based and Other Compensation Plans

The Company grants stock options, stock appreciation rights (“SARs”), performance-based awards, and time-based restricted shares, some of which are cash-payment awards, with the final award payment indexed to the percentage change in the Company’s stock price from the date of grant.

The Company recognized stock-based compensation expense of $1.3 million and $4.8 million for the three and six months ended June 30, 2012, respectively. For the three and six months ended June 30, 2011, the Company recognized stock-based compensation expense of $2.3 million and $3.7 million, respectively. As of June 30, 2012, there was $8.6 million of unrecognized compensation expense related to these awards. The remaining compensation expense for the stock options, SARs and restricted awards is expected to be recognized over a weighted-average period of approximately two years, and the remaining expense for performance-based awards will be recognized within approximately one year.

The Company also has deferred compensation plans for its Board of Directors and certain executives. Under these plans, participants can elect to invest their deferrals in the Company’s common stock. At June 30, 2012 and 2011, there were 0.7 million common shares deferred. As these awards can be settled in cash, the Company records compensation costs each period based on the change in the Company’s stock price. The Company recognized a gain of $0.2 million and expense of $0.5 million for the three and six months ended June 30, 2012, respectively. For the three and six months ended June 30, 2011, the Company recognized expense of $0.4 million and $0.3 million, respectively.

In 2010, the Company's Board of Directors approved a new long-term incentive program for certain members of management. Payment is contingent upon the completion of a qualifying transaction and attainment of an increase in the equity value of the data center business, as defined in the plans. As of June 30, 2012, the Compensation Committee of the Company's Board of Directors has approved grants that could result in a maximum payout up to $90 million assuming the equity value created is $1.0 billion. For the quarter ended June 30, 2012, no compensation expense was recorded for these awards.
