Share Options And Awards

Share Options and Awards

In April 2011, our Long-Term Incentive Plan for the issuance of options and share awards expired, and issued options of 3.4 million remain outstanding as of December 31, 2012.

In May 2010, our shareholders approved the adoption of the Amended and Restated 2010 Long-Term Incentive Plan, under which 3.0 million of our common shares were reserved for issuance, and options and share awards of 1.9 million are available for future grant at December 31, 2012. This plan expires in May 2020.

Compensation expense, net of forfeitures, associated with share options and restricted shares totaled $9.7 million in 2012, $6.4 million in 2011 and $4.9 million in 2010, of which $2.0 million in 2012, $1.5 million in 2011 and $1.2 million in 2010 was capitalized. The significant year over year change in expense is primarily due to an increased number of employees who became retirement eligible, requiring the related expense to be recognized immediately.

Options

The fair value of share options issued prior to 2012 was estimated on the date of grant using the Black-Scholes option pricing method based on the expected weighted average assumptions in the following table. The fair value and weighted average assumptions were as follows:

	Year Ended December 31,
	2011			2010
Fair value per share option	$	5.68		$	5.42
Dividend yield	5.3		%	5.3		%
Expected volatility	39.6		%	38.8		%
Expected life (in years)	6.2			6.2
Risk-free interest rate	2.4		%	2.9		%

Following is a summary of the option activity for the three years ended December 31, 2012:

	Shares Under Option		Weighted Average Exercise Price
Outstanding, January 1, 2010	4,436,143		$	27.44

Exercised	(481,611	)	20.70
Outstanding, December 31, 2012	4,085,702		$	28.98

The total intrinsic value of options exercised was $3.0 million in 2012, $1.9 million in 2011 and $1.8 million in 2010. As of December 31, 2012 and 2011, there was approximately $2.2 million and $3.8 million, respectively, of total unrecognized compensation cost related to unvested share options, which is expected to be amortized over a weighted average of 1.6 years and 2.4 years, respectively.

The following table summarizes information about share options outstanding and exercisable at December 31, 2012:

Dividend yield	0.0	%	4.4	%
Expected volatility	27.7	%	51.6	%
