Stock-Based Incentive Plan [Abstract]

Stock-Based Incentive Plan

Note 11. Stock-Based Incentive Plan

The Corporation has a shareholder-approved 2003 Long-Term Incentive Plan under which the Corporation may grant options and share awards to employees up to 1,500,000 shares of common stock. The plan provides for the issuance of options to purchase common shares at prices not less than 100 percent of the fair market value at the date of option grant and have a contractual term of ten years; and for restricted stock awards valued at not less than 100 percent of the fair market value at the date of award grant. For the majority of options issued, after two years, 33.3 percent of the optioned shares become exercisable in each of the following three years and remain exercisable for a period not exceeding ten years from the date of grant. For the majority of the restricted stock awards, the restriction lapses over a three-year period at 33.3 percent per year. There were 612,726 share awards available for future grants at December 31, 2012 under the plan. At December 31, 2012, there were 584,349 options to purchase common stock and 175,008 unvested restricted stock awards outstanding under the plan.

Following is a summary of the status of options under the 2003 Long-term Incentive Plan during 2012:

(Dollars in thousands)	Shares Under Option			Weighted Average Exercise  Price Per Share		Weighted Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value at December 31, 2012

There were no stock options exercised during 2010, 2011 or 2012. The Corporation has a stock-for-stock-option exchange (or cashless exercise) program in place, whereby optionees can exchange the value of the spread of in-the-money vested options for Corporation stock having an equivalent value. This broker-assisted exchange allows the optionees to exercise their vested options on a net basis without having to pay the exercise price or related expenses in cash. However, it will result in the optionees acquiring fewer shares than the number of options exercised.

The Corporation’s estimate of the fair value of a stock option is based on expectations derived from historical experience and may not necessarily equate to its market value when fully vested. The life of the option is based on historical factors which include the contractual term, vesting period, exercise behavior and employee turnover. The risk-free rate for periods within the expected term of the option is based on the U.S. Treasury strip rate in effect at the time of grant. Expected volatility is based on the historical volatility of the Corporation’s stock over the expected life of the grant. The Corporation uses a straight-line accrual method to recognize stock-based compensation expense over the time-period it expects the options to vest.

The Corporation recognizes compensation expense for stock options over the requisite service period based on the grant-date fair value of those awards expected to ultimately vest. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original estimates. The following aggregated assumptions were used to estimate the fair value of options granted during fiscal years 2012, 2011 and 2010:

	For the Years Ended December 31,
	2012			2011			2010
Expected option life in years		8.2			7.9			8.0
Risk free interest rate		1.63	%		3.04	%		3.60	%
Expected dividend yield		5.40	%		4.64	%		4.55	%
Expected volatility		50.74	%		49.11	%		47.16	%
Fair value of options	$	4.37		$	5.72		$	5.81

Following is a summary of nonvested restricted stock awards at December 31, 2012 including changes during the year:

(Dollars in thousands)	Nonvested Share Awards			Weighted Average Grant Date Fair Value
Nonvested share awards at December 31, 2011		156,297		$	19.08
Granted		71,157			15.29
Vested		(39,321	)		21.54
Forfeited		(13,125	)		22.90
Nonvested share awards at December 31, 2012		175,008			16.70

The fair value of restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period. Certain information regarding restricted stock for the following periods is summarized below:

(Dollars in thousands, except share and per share data)	Years Ended December 31,
	2012		2011		2010
Shares granted		71,157		58,736		67,982
Weighted average grant date fair value	$	15.29	$	17.34	$	17.62
Intrinsic value of awards vested	$	625	$	183	$	138

At December 31, 2012, there was $1.3 million in total unrecognized compensation expense related to nonvested share-based compensation arrangements, which is expected to be recognized over a weighted average period of 2.5 years.

The following table presents information related to the Corporation’s compensation expense related to stock incentive plans recognized for the years ended December 31, 2012, 2011 and 2010:
