Stock Options Activity

Stock Options
We use the Black-Scholes option pricing model to estimate the fair value of our stock options; however there have been no stock options granted during 2013, 2012 or 2011.
The following table presents our stock option activity for 2013:
		Number of Shares	Weighted Average Exercise Price		Weighted Average Contractual Life (Years)
Outstanding options at January 1, 2013		243,886	$	20.08	1.66
	Exercised	(37,558)		6.95
	Canceled, forfeited or expired	(11,835)		20.02
Outstanding options at December 31, 2013		194,493	$	22.62	0.83
Exercisable options at December 31, 2013		194,493	$	22.62	0.83
The aggregate intrinsic value of our outstanding options and exerciseable options at December 31, 2013 was less than $0.1 million. Total intrinsic value of options exercised was $0.2 million, $0.1 million and $0.7 million for 2013, 2012 and 2011, respectively.
All of our outstanding options were vested as of October 2008; therefore there was no non-vested stock option activity for 2013.

Non-Vested Stock Activity

Non-Vested Stock
We issue shares of non-vested stock with vesting terms ranging from one to five years. The compensation expense is determined based on the market price of our common stock at the date of grant applied to the total number of shares that are anticipated to fully vest. Non-vested stock compensation expense included in general and administrative expenses in our accompanying consolidated income statements was $5.2 million, $6.4 million and $7.2 million for 2013, 2012 and 2011, respectively.
The following table presents our non-vested stock award activity for 2013:
		Number of Shares	Weighted Average Grant Date Fair Value
Non-vested stock at January 1, 2013		643,353	$	20.76
	Granted	499,049		10.91
	Vested	(296,597)		24.29
	Canceled, forfeited or expired	(72,314)		15.23
Non-vested stock at December 31, 2013		773,491	$	13.56
The weighted average grant date fair value of non-vested stock granted was $10.91, $14.01 and $27.05 in 2013, 2012, and 2011, respectively. At December 31, 2013, there was $4.0 million of unrecognized compensation cost related to non-vested stock award payments that we expect to be recognized over a weighted average period of 1.3 years.
