13. STOCK-BASED COMPENSATION

Since 1973, PLC has had stock-based incentive plans to motivate management to focus on its long-range performance through the awarding of stock-based compensation. Under plans approved by shareowners in 1997, 2003, 2008, and 2012, up to 9,500,000 PLC shares may be issued in payment of awards.

The criteria for payment of the 2012 performance awards is based on PLC’s average operating return on average equity (“ROE”) over a three-year period. If PLC’s ROE is below 10.0%, no award is earned. If PLC’s ROE is at or above 11.2%, the award maximum is earned. The criteria for payment of the 2011 performance awards is based on PLC’s ROE (excluding certain accounting and operating income definition changes) over a three-year period. If PLC’s ROE is below 9%, no award is earned. If PLC’s ROE is at or above 10.0%, the award maximum is earned. Awards are paid in shares of PLC’s common stock. Performance shares are equivalent in value to one share of our common stock times the award earned percentage payout. Performance share awards of 306,100 were issued during the year ended December 31, 2012 and 191,000 performance share awards were issued during the year ended December 31, 2011.

Performance share awards in 2012 and 2011 and the estimated fair value of the awards at grant date are as follows:

Year	Performance	Estimated
Awarded	Shares	Fair Value
		(Dollars In Thousands)
2012	306,100	$	8,608
2011	191,100	5,433
2010	—	—

Stock appreciation rights (“SARs”) of PLC have been granted to certain officers to provide long-term incentive compensation based solely on the performance of PLC’s common stock. The SARs are exercisable either five years after the date of grants or in three or four equal annual installments beginning one year after the date of grant (earlier upon the death, disability, or retirement of the officer, or in certain circumstances, of a change in control of PLC) and expire after ten years or upon termination of employment. The SARs activity as well as weighted-average base price is as follows:

	Weighted-Average
	Base Price per share		No. of SARs

The outstanding SARs as of December 31, 2012, were at the following base prices:

		SARs	Remaining Life	Currently
Base Price		Outstanding	in Years	Exercisable
$	26.49	50,000	1	50,000

There were no SARs issued for the years ended December 31, 2012 and 2011. The SARs issued for the year ended December 31, 2010, had estimated fair values at grant date of $3.3 million. These fair values were estimated using a Black- Scholes option pricing model. The assumptions used in this pricing model varied depending on the vesting period of awards. Assumptions used in the model for the 2010 SARs granted (the simplified method under the ASC Compensation-Stock Compensation Topic was used for the 2010 awards) were as follows: an expected volatility of 69.4%, a risk-free interest rate of 2.6%, a dividend rate of 2.4%, a zero percent forfeiture rate, and an expected exercise date of 2016.

Restricted stock units are awarded to participants and include certain restrictions relating to vesting periods. PLC issued 190,800 restricted stock units for the year ended December 31, 2012 and 175,500 restricted stock units for the year ended December 31, 2011. These awards had a total fair value at grant date of $5.4 million and $5.0 million, respectively. Approximately half of these restricted stock units vest after three years from grant date and the remainder vest after four years.

PLC recognizes all stock-based compensation expense over the related service period of the award, or earlier for retirement eligible employees. The expense recorded by PLC for its stock-based compensation plans was $10.3 million, $10.2 million, and $10.2 million in 2012, 2011, and 2010, respectively. The Company recognized expense associated with PLC’s stock-based compensation plans for compensations awarded to its employees of $3.9 million, $2.7 million, and $3.0 million in 2012, 2011, and 2010, respectively. PLC’s obligations of its stock-based compensation plans that are expected to be settled in shares of PLC’s common stock are reported as a component of shareowners’ equity, net of deferred taxes.
