Equity Based Compensation [Abstract]

EQUITY BASED COMPENSATION

NOTE 8 — EQUITY BASED COMPENSATION

We provide stock-based awards as a form of compensation for certain employees and officers. We have issued stock-based awards in the form of stock options. We recorded total stock compensation expense of $1.4 million and $1.0 million for the six months ended June 30, 2011 and 2010, respectively ($0.6 million and $0.7 million for the second quarter of 2011 and 2010, respectively). The compensation expense is principally included in Selling, General and Administrative Expenses in the accompany Condensed Consolidated Statements of Operations.

Below is a summary of the different types of stock-based awards issued under our stock plans:

Stock Options

Service-based Options. These options are granted at fair market value on the date of grant. The options generally vest over four years with equal annual cliff-vesting and expire on the earlier of 10 years after the date of grant or following termination of service. A total of 1.1 million service-based awards were outstanding at June 30, 2011.

Market-based Options. These option grants have two components each of which vest only upon the achievement of certain criteria. The first component, which we refer to internally as “ordinary performance” grants, consists of two-thirds of the market-based grant and begins to vest if the stock price realizes a compounded annual gain of at least 20% over the exercise price, so long as the stock price is at least double the exercise price. The remaining third of the market-based options, which we refer to internally as “extraordinary performance” grants, begins to vest if the stock price realizes a compounded annual gain of at least 25% over the exercise price, so long as it is at least triple the exercise price. The vesting schedule for all market-based awards is 25% upon achievement of the criteria and the remaining 75% in three equal annual installments. A total of 2.2 million market-based awards were outstanding at June 30, 2011.

During the six months ended June 30, 2011, the Company granted 0.1 million stock options. The options have an average exercise price of $29.99 per share.

The fair value of the service-based options was determined using the Black-Scholes options pricing model while a lattice (binomial) model was used to determine the fair value of the market-based options using the following assumptions as of the grant date:

	June 30, 2011						June 30, 2010
	Black-Scholes			Binominal			Black-Scholes			Binominal
Risk-free Interest Rate		2.20	%		0.03%–3.18	%		2.82	%		0.17%–3.36	%
Expected Stock Price Volatility		48	%		55.9	%		48	%		51.5	%
Expected Dividend Yield		—			—			—			—
Expected Option Life (in years)		6.25			—			7			—
Contractual Life (in years)		—			14			—			14
Fair Value	$	16.55		$18.09 and $18.76			$	13.00		$10.50 and $12.35

The following table summarizes the weighted-average fair value of stock options granted, and the total intrinsic value of stock options exercised:

	June 30
(in thousands, except per share amounts)	2011		2010
Weighted-Average Fair Value at Date of Grant Per Share	$	16.03	$	11.58
Intrinsic Value of Options Exercised	$	2,855	$	1,827
Fair Value of Options Vested	$	788	$	131

Stock-based compensation expense is recorded net of estimated forfeiture rates ranging from 1% to 3%.

As of June 30, 2011, estimated unrecognized compensation costs related to share-based payments amounted to $7.0 million which we expect to recognize over a weighted-average remaining requisite service period of approximately 3.1 years.

The following table summarizes activity of our stock options:
