Share-Based Compensation

We estimate our pre-tax share-based compensation expense to be approximately $3.6 million in 2014 based on our current share-based compensation arrangements. The pre-tax share-based compensation expense that has been charged against income for the share-based compensation arrangements was approximately $5.3 million, $4.7 million and $3.6 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Stock Option Grants — In October 2004, we granted options to purchase 598,950 shares of common stock at $15.84 per share. These options have a ten-year term and vest ratably in three equal annual installments commencing on October 20, 2005. As of December 31, 2008, there was no amount remaining of unearned compensation related to nonvested stock options granted in October 2004 under the amended and restated equity incentive plan.

Restricted Stock Awards — Restricted stock is a grant of shares of common stock that may not be sold, encumbered or disposed of, and that may be forfeited in the event of certain terminations of employment, prior to the end of a restricted period set by the compensation committee of the board of directors. A participant granted restricted stock generally has all of the rights of a stockholder, unless the compensation committee determines otherwise. The following table summarizes information about restricted stock grants (in millions, except for share data):


Grant	Shares		Vesting Schedule	Unearned Compensation		Remaining Period (in months)
November 2011		443,250	3 equal annual installments commencing on October 20, 2012	$	1.2		10
November 2012		494,151	3 equal annual installments commencing on October 20, 2013	$	2.0		22
August 2013		100,000	3 equal annual installments commencing on October 20, 2014	$	0.7		34
November 2013		470,997	3 equal annual installments commencing on October 20, 2014	$	2.9		34

As of December 31, 2013, there was approximately $6.8 million of unearned compensation expense related to non-vested share-based compensation arrangements granted under our equity incentive plans. This expense is subject to future adjustments for vesting and forfeitures and will be recognized on a straight-line basis over the remaining period listed above for each grant.

We currently estimate the forfeiture rate for November 2013, November 2012 and November 2011 restricted stock awards at 8.2%, 8.2% and 8.2%, respectively, for all participants of each plan. A summary of the status of our stock options as of December 31, 2013 and changes during the twelve-month period ending December 31, 2013 is presented below:

We expect employees to surrender approximately 161 thousand shares of our common stock in connection with the vesting of restricted stock during 2014 to satisfy income tax withholding obligations.

As of December 31, 2013, a total of 625,052 shares were available from the 4.6 million shares authorized for award under our Fourth Amended and Restated Equity Incentive Plan, including cumulative forfeitures.

Repurchase of Common Stock — We did not repurchase any of our common stock on the open market as part of a stock repurchase program during 2013; however, our employees surrendered 99 thousand shares of our common stock to satisfy tax withholding obligations on the vesting of restricted stock awards issued under our Fourth Amended and Restated Equity Incentive Plan.
