STOCK-BASED COMPENSATION

We have granted stock options and restricted stock awards under two stock incentive plans: the 2007 Long-Term Incentive Plan (the "Plan") and the 2006 Non-employee Director Stock Incentive Plan (the "Director Plan "). Awards under the following two compensation programs have been granted pursuant to the Plan: (1) the Performance Share Award Program ("PSAP") and (2) the Restricted Share Award Program ("RSAP").

Since the inception of the Plan in 1995 until 2001, we awarded stock options as the primary form of equity compensation. In 2001, we reassessed the form of award and elected to begin the use of restricted share grants which we believe are a stronger motivational tool for our employees. Restricted share awards provide some value to an employee during periods of stock market volatility, whereas stock options may have limited perceived value and may not be as effective in retaining and motivating employees when the current value of our stock is less than the option price. Currently, our long-term equity incentive compensation is exclusively in the form of restricted shares and performance restricted shares as no stock options were granted during 2011.

We issue shares from either treasury stock or authorized shares upon the exercise of options or lapsing of vesting restrictions on restricted stock. In 2011, we issued 42,400 shares and 177,271 shares out of treasury stock relating to the exercise of stock options and the vesting of restricted stock, respectively. We do not use cash to settle equity instruments issued under stock-based compensation awards.

2007 Long-term Incentive Plan

On April 2, 2007, the 1995 Long-Term Incentive Plan was amended, restated and renamed as the 2007 Long-Term Incentive Plan. The primary changes effected by the 2007 amendment and restatement was to (a) extend the period during which awards may be granted under the Plan to February 13, 2017, (b) require all stock options awarded under the Plan to have an exercise price per share that is at least equal to the fair market value of a common share as of the date of grant of the option (subject to adjustment under certain circumstances, such as upon a reorganization, stock split, recapitalization, or other change in our capital structure), (c) provide that stock appreciation rights may be granted under the Plan, (d) prohibit the repricing of stock options awarded under the Plan, (e) provide that no amendment to the Plan that would require shareholder approval pursuant to the requirements of the New York Stock Exchange or any exchange on which we are listed will be effective prior to approval of our shareholders, and (f) expand the performance goals enumerated under the Plan upon which restricted share awards may be based. The amendment and restatement of the Plan does not increase the number of common shares subject to the Plan. The Plan provides for a maximum of 10,800,000 common shares to be granted to eligible employees. At December 31, 2011, approximately 598,574 shares were available for the grant of new awards under the Plan. Specifically, we encourage share ownership by awarding various long-term equity incentive awards under the Plan, consisting of the PSAP and RSAP. We believe that widespread common share ownership by key employees is an important means of encouraging superior performance and employee retention. Additionally, our equity-based compensation programs encourage performance and retention by providing additional incentives for executives to further our growth, development and financial success over a longer time horizon by personally benefiting through the ownership of our common shares and/or rights.

Performance Share Award Program

On April 1, 2010, certain executives were awarded rights to receive an aggregate of 90,000 common shares if our calculated return on invested capital ("ROIC"), as defined in the PSAP, is in the top decile of the Bloomberg Peer Group at the end of the three year performance period, which ends on December 31, 2012. Unless there is a change in control as defined in the PSAP, none of these awards will vest if the specified performance target is not met as of the last day of the performance period. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $5.8 million over a 33-month period that began on April 1, 2010, of which $2.1 million and $1.6 million has been recognized in 2011 and 2010, respectively. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 12 months.

On April 1, 2011, certain executives were awarded rights to receive an aggregate of 86,207 common shares if our calculated ROIC, as defined in the PSAP, is in the top decile of the Bloomberg Peer Group at the end of the three year performance period, which ends on December 31, 2013. Unless there is a change in control as defined in the PSAP, none of these awards will vest if the specified performance target is not met as of the last day of the performance period. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $8.7 million over a 33-month period that began on April 1, 2011, of which $2.4 million has been recognized in 2011. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 24 months.

Restricted Share Award Program

In 2004, the Equity Awards Subcommittee of our Compensation Committee of our Board of Supervisory Directors approved the RSAP to attract and retain the best employees, and to better align employee interests with those of our shareholders. Under this arrangement we awarded grants totaling 95,760 shares, 142,070 shares, and 123,550 shares in 2011, 2010, and 2009, respectively. Each of these grants has a vesting period of principally six years and vests ratably on an annual basis. There are no performance accelerators for early vesting for these awards. Awards under the RSAP are classified as an equity award and recorded at the grant-date fair value and the compensation expense is being recognized over the expected life of the award. As of December 31, 2011, there was $30.7 million of unrecognized total stock-based compensation relating to non-vested RSAP awards. The unrecognized compensation expense is expected to be recognized over an estimated weighted-average amortization period of 50 months. The grant-date fair value of shares granted was $10.6 million, $12.3 million and $10.8 million in 2011, 2010 and 2009, respectively and we have recognized compensation expense of $12.4 million, $6.1 million and $5.0 million in 2011, 2010 and 2009, respectively. The total grant-date fair value, which is the intrinsic value of the shares, vested was $8.4 million, $7.0 million and $5.7 million in 2011, 2010 and 2009, respectively. We have recognized a tax benefit from the vesting of the RSAP of $2.6 million, $1.0 million and $0.2 million in 2011, 2010 and 2009, respectively.

2006 Non-employee Director Stock Incentive Plan

The Director Plan provides common shares for grant to our eligible Supervisory Directors. The maximum number of shares available for award under this plan is 1,400,000 common shares. As of December 31, 2011 approximately 576,134 shares were available for issuance under the Director Plan. On June 28, 2006, the 1995 Non-employee Director Stock Option Plan was amended, restated and renamed as the 2006 Non-employee Director Stock Incentive Plan. The primary change effected by the 2006 amendment was to eliminate the automatic, formula grant of stock options under the prior plan and to replace that formula approach with the discretionary right of the Supervisory Board to grant stock options, restricted shares, or any combination thereof. Only non-employee Supervisory Directors are eligible for these equity-based awards under the Director Plan.

Performance Share Award Program

On July 15, 2008, we awarded rights relating to an aggregate of 8,904 PSAP shares under the Director Plan to our non-employee Supervisory Directors for which the performance period began on July 15, 2008 and ended on July 15, 2011. The performance target for this award was based on a calculated return on equity ("ROE"), as defined in the agreement, with full vesting occurring if our ROE equaled or exceeded the pre-determined target ROE of 200% at the end of the three-year performance period. If our ROE for the performance period did not meet the target ROE but equaled or exceeded 160%, then the number of shares to be issued would be interpolated based on the terms of the agreement. This arrangement was recorded as an equity award that required us to recognize compensation expense totaling $0.6 million over a three-year period that began on July 15, 2008, of which, $0.2 million, $0.2 million and $0.2 million has been recognized in 2011, 2010 and 2009, respectively. On July 15, 2011, at the end of the three-year performance period, it was determined that the vesting criteria were not met and the awarded shares were forfeited in full. Accordingly, the $0.6 million in expense was reversed.

On July 15, 2009, we awarded rights relating to an aggregate of 13,884 PSAP shares under the Director Plan to our non-employee Supervisory Directors for which the performance period began on July 15, 2009 and ends on July 15, 2012. The performance target for this award is based on a calculated ROE, as defined in the agreement, with full vesting occurring if our ROE equals or exceeds the returns earned by members of the S&P 500 Oil & Gas Equipment & Services index, with 50% of the shares vesting if our return is at or above the 50^th percentile of the members' return and 100% of the shares vesting if our return is at or above the 75^th percentile of the members' return. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $0.6 million over a three-year period that began on July 15, 2009, of which $0.2 million, $0.2 million and $0.1 million has been recognized in 2011, 2010 and 2009, respectively. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 7 months.

On April 1, 2010, we awarded rights relating to an aggregate of 9,180 PSAP shares under the Director Plan to our non-employee Supervisory Directors for which the performance period began on January 1, 2010 and ends on December 31, 2012. The performance target for this award is based on a calculated ROIC, as defined in the agreement, with full vesting occurring if our ROIC is in the top decile of the Bloomberg Peer Group at the end of the performance period. Unless there is a change in control, as defined in the PSAP, none of the awards will vest if the specified performance target is not met as of the last day of the performance period. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $0.6 million over a 33-month period that began on April 1, 2010, of which, $0.2 million and $0.2 million has been recognized in 2011 and 2010, respectively. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 12 months.

Restricted Share Award Program

In 2011, the Equity Awards Subcommittee of our Compensation Committee of our Board of Supervisory Directors approved the RSAP to compensate our non-employee Supervisory Directors. Prior to 2011, the non-employee Supervisory Directors were awarded shares under the PSAP plan. Under this arrangement we awarded grants totaling 10,283 shares in 2011 which vest on December 31, 2013. There are no performance accelerators for early vesting for these awards. Awards under the RSAP are classified as an equity award and recorded at the grant-date fair value and the compensation expense is being recognized over the expected life of the award. As of December 31, 2011, there was $0.8 million of unrecognized total stock-based compensation relating to non-vested RSAP awards. The unrecognized compensation expense is expected to be recognized over an estimated weighted-average amortization period of 27 months. The grant-date fair value of shares granted was $1.0 million in 2011, and we have recognized compensation expense of $0.2 million in 2011.
