STOCK-BASED COMPENSATION

At March 31, 2013, LP had stock-based employee compensation plans as described below. The total compensation expense related to all of LP’s stock-based compensation plans was $2.1 million for the quarter ended March 31, 2013 as compared to $2.7 million for the quarter ended March 31, 2012. Included in total stock compensation expense for the first quarter ended March 31, 2012, is stock compensation expense of $1.0 million related to awards granted to LP's retired Chief Executive Officer.

Stock Compensation Plans

LP grants options to purchase LP common stock and stock settled stock appreciation rights (SSARs) to key employees and directors. On exercise, LP generally issues shares from treasury to settle these awards. The options and SSARs are granted at market price at the date of grant. For employees, SSARs become exercisable ratably over a three year period and expire ten years after the date of grant. For directors, these options become exercisable in 10% increments every three months, starting three months after the date of grant, and expire ten years after the date of grant. At March 31, 2013, 4.3 million shares were available under the current stock award plans for stock-based awards.

The following table sets out the weighted average assumptions used to estimate the fair value of the options and SSARs granted using the Black-Scholes option-pricing model in the first three months of the respective years noted:



	2013	2012
Expected stock price volatility	69.2%	63.3%
Expected dividend yield	—%	—%
Risk-free interest rate	0.9%	0.7%
Expected life of options	5 years	5 years
Weighted average fair value of options and SSARs granted	$11.68	$4.68

The following table summarizes stock options and SSARs outstanding as of March 31, 2013, as well as activity during the three month period then ended.



Share amounts in thousands	Options and SSARs		Weighted Average Exercise Price		Weighted Average Contractual Term (in years)	Aggregate Intrinsic Value (in millions)
Options / SSARs outstanding at January 1, 2013	8,475		$	12.88
SSARs granted	343		20.49
Options / SSARs exercised	(1,805	)	9.13
Options /SSARs canceled	—		—
Options/SSARs outstanding at March 31, 2013	7,013		$	14.22	5.7	$	57.4
Vested and expected to vest at March 31, 2013	6,663		—		—	$	54.6
Options/SSARS exercisable at March 31, 2013	5,719		$	14.70	—	$	45.2

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between LP's closing stock price on the last trading day of the first quarter of 2013 and the exercise price, multiplied by the number of in-the-money options and SSARs) that would have been received by the holders had all holders exercised their awards on March 31, 2013. This amount changes based on the market value of LP's stock as reported by the New York Stock Exchange.

As of March 31, 2013, there was $6.8 million of total unrecognized compensation costs related to stock options and SSARs. These costs are expected to be recognized over a weighted-average period of 1.9 years. LP recorded compensation expense related to these awards in the first three months of 2013 of $0.8 million.

Incentive Share Awards

LP has granted incentive share stock awards (restricted stock units) to certain key employees as allowed under the current stock award plans. The awards vest three years from date of grant. The awards entitle the participant to receive a specified number of shares of LP common stock at no cost to the participant. The market value of these grants approximates the fair value. LP recorded compensation expense related to these awards in the first three months of 2013 of $0.6 million. As of March 31, 2013, there was $4.7 million of total unrecognized compensation cost related to unvested incentive share awards. This expense will be recognized over a weighted-average period of 1.6 years.

The following table summarizes incentive share awards outstanding as of March 31, 2013 as well as activity during the three months then ended.



	Shares		Weighted Average Contractual Term (in years)	Aggregate Intrinsic Value (in millions)
Incentive share awards outstanding at January 1, 2013	960,388
Incentive share awards granted	123,286
Incentive share awards vested	(341,607	)
Incentive share awards canceled	(478	)
Incentive shares outstanding at March 31, 2013	741,589		1.6	$	16.0
Vested and expected to vest at March 31, 2013	704,510		—	$	15.2
Incentive share awards exercisable at March 31, 2013	—		—	—

Restricted Stock

LP grants restricted stock to certain senior employees. The shares vest three years from the date of grant. During the vesting period, the participants have voting rights and receive dividends, but the shares may not be sold, assigned, transferred, pledged or otherwise encumbered. Additionally, granted but unvested shares are forfeited upon termination of employment. The fair value of the restricted shares on the date of the grant is amortized ratably over the vesting period which is generally three years. As of March 31, 2013, there was $3.8 million of total unrecognized compensation costs related to restricted stock. This expense will be recognized over the next 1.8 years. LP recorded compensation expense related to these awards in the first three months of 2013 of $0.4 million.

The following table summarizes the restricted stock outstanding as of March 31, 2013 as well as activity during the three months then ended.



	Number of Shares		Weighted Average Grant Date Fair Value
Restricted stock awards outstanding at January 1, 2013	556,987		$	8.51
Restricted stock awards granted	108,174		20.49
Restrictions lapsed	(205,739	)	7.00
Restricted stock awards at March 31, 2013	459,422		$	12.01

LP annually grants to each director restricted stock or restricted stock units. As of March 31, 2013, LP has 77,533 shares (or restricted stock units) outstanding under this program.

Performance share awards

In connection with Mr. Stevens' appointment to Chief Executive Officer on May 4, 2012, he was awarded 300,000 performance shares. LP recorded compensation expense related to these awards of $0.1 million in the first three months of 2013. As of March 31, 2013, there was $1.1 million of total unrecognized compensation costs related to this award. This expense will be recognized over the next 3.1 years.

Phantom stock

Beginning in 2011, LP annually grants phantom stock units to its directors. The director does not receive rights of a shareholder, nor is any stock transfered. The units will be paid out in cash at the end of the five year vesting period. The value of one unit is based on the market value of one share of common stock on the vesting date. The cost of the grants is recognized over the vesting period and is included in stock-based compensation expense. As of March 31, 2013, LP had 75,816 shares outstanding under this program. LP recorded compensation expense related to these awards of $0.2 million in the first three months of 2013.
