Stock-Based Compensation

Note 3. Stock-Based Compensation

The Corporation maintains two stock-based compensation plans from which new grants could be issued. The Corporation's stock option plans permit Parent Corporation common stock to be issued to key employees and directors of the Corporation and its subsidiaries. The options granted under the plans are intended to be either incentive stock options or non-qualified options. Under the 2009 Equity Incentive Plan, a total of 394,417 shares are available for grant and issuance as of March 31, 2012. Under the 2003 Non-Employee Director Stock Option Plan, a total of 403,219 shares remain available for grant and issuance under the plan as of March 31, 2012 and are authorized for issuance. Such shares may be treasury shares, newly issued shares or a combination thereof.

Options have been granted to purchase common stock principally at the fair market value of the stock at the date of grant. Options are exercisable over a three year vesting period starting one year after the date of grant and generally expire ten years from the date of grant.

Stock-based compensation expense for all share-based payment awards granted after December 31, 2005 is based on the grant date fair value estimated in accordance with the provisions of FASB ASC 718-10-10 "Stock Based Compensation". The Corporation recognizes these compensation costs net of a forfeiture rate and recognizes the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of 3 years. The Corporation estimated the forfeiture rate based on its historical experience during the preceding seven fiscal years.

For the three months ended March 31, 2012, the Corporation's income before income taxes and net income were reduced by $7,000 and $4,000, respectively, as a result of the compensation expense related to stock options. For the three months ended March 31, 2011, the Corporation's income before income taxes and net income were reduced by $8,000 and $5,000, respectively, as a result of the compensation expense related to stock options.

Under the principal option plans, the Corporation may also grant restricted stock awards to certain employees. Restricted stock awards are non-vested stock awards. Restricted stock awards are independent of option grants and are generally subject to forfeiture if employment terminates prior to the release of the restrictions. Such awards generally vest within 30 days to five years from the date of grant. During that period, ownership of the shares cannot be transferred. Restricted stock has the same cash dividend and voting rights as other common stock and is considered to be currently issued and outstanding. The Corporation expenses the cost of restricted stock awards, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which the restrictions lapse. There were no restricted stock awards outstanding at March 31, 2012 or March 31, 2011.

There were 27,784 and 30,564 shares of common stock underlying granted options for the three months ended March 31, 2012 and 2011, respectively. The fair value of share-based payment awards was estimated using the Black-Scholes option pricing model with the following assumptions and weighted average fair values at the time the grants were awarded:

Weighted average fair value of grants   $ 2.03     $ 1.89  
Risk-free interest rate     2.03 %      2.19 % 
Dividend yield     1.24 %      1.32 % 
Expected volatility     22.04 %      22.25 % 
Expected life in months     68       65  

Activity under the principal option plans as of March 31, 2012 and changes during the three months ended March 31, 2012 were as follows:

Outstanding at March 31, 2012     199,162       9.96       6.27     $ 146,074  
Exercisable at March 31, 2012     130,574     $ 10.42       4.87     $ 80,894  

The aggregate intrinsic value of options above represents the total pre-tax intrinsic value (the difference between the Corporation's closing stock price on the last trading day of the first quarter of 2012 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on March 31, 2012. This amount changes based on the fair value of the Corporation's stock.

As of March 31, 2012, there was approximately $102,000 of total unrecognized compensation expense relating to unvested stock options. These costs are expected to be recognized over a weighted average period of 1.58 years.
