8. STOCK-BASED COMPENSATION

During the three months ended March 31, 2013, 298,500 performance shares with an estimated fair value of $9.3 million were awarded. The criteria for payment of the 2013 performance awards is based primarily 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 11.5%, the award maximum is earned. Awards are paid in shares of PLC’s common stock.

Restricted stock units are awarded to participants and include certain restrictions relating to vesting periods. PLC issued 141,000 restricted stock units for the three months ended March 31, 2013. These awards had a total fair value at grant date of $4.4 million. Approximately half of these restricted stock units vest in 2016, and the remainder vest in 2017. These awards have been recorded as equity-classified awards for the period ended March 31, 2013.

Stock appreciation rights (“SARs”) of PLC have historically 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
Balance at December 31, 2012	$	22.15	1,641,167
SARs granted	—		—
SARs exercised / forfeited	22.83		69,899
Balance at March 31, 2013	$	22.12	1,571,268

There were no SARs issued for the three months ended March 31, 2013. PLC will pay an amount in stock equal to the difference between the specified base price of PLC’s common stock and the market value at the exercise date for each SAR.
