STOCK COMPENSATION EXPENSE [Abstract]  
STOCK COMPENSATION EXPENSE
NOTE  6 – STOCK COMPENSATION EXPENSE

From time to time the Company grants stock options to its employees.  The Company estimates the fair value of the options at the time they are granted to employees and expenses that fair value over the vesting period of the option grant.

On March 20, 2013, 52,900 incentive stock options were granted out of the 2012 Long Term Incentive Plan at an exercise price of $11.39, the closing market price of Premier's common stock on the grant date.  These options vest in three equal annual installments ending on March 20, 2016.  On March 21, 2012, 105,700 incentive stock options were granted out of the 2002 Employee Stock Option Plan at an exercise price of $7.47, the closing market price of Premier's common stock on the grant date.  These options vest in three equal annual installments ending on March 21, 2015.  On March 18, 2011, 102,000 incentive stock options were granted out of the 2002 Employee Stock Option Plan at an exercise price of $6.95 the closing market price of Premier on the grant date.  These options vest in three equal annual installments ending on March 18, 2014.

The fair value of the Company's employee stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there may be other factors that would otherwise have a significant effect on the value of employee stock options granted but are not considered by the model. The assumptions used in the Black-Scholes option-pricing model are as follows

The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield in effect at the time of the grant.  The expected option life was estimated since there has been little option exercise history.  The expected stock price volatility is based on historical volatilities of the Company's common stock.  The dividend yield was estimated using historical dividends and dividend yields since at the time of the option grant the Company is restricted from paying dividends by its primary regulator.

Compensation expense of $46,000 was recorded for the first three months of 2013 while $28,000 was recorded for the first three months of 2012.  Stock-based compensation expense is recognized ratably over the requisite vesting period for all awards. Unrecognized stock-based compensation expense related to stock options totaled $243,000 at March 31, 2013. This unrecognized expense is expected to be recognized over the next 35 months based on the vesting periods of the options.

A summary of the Company's stock option activity and related information is presented below for the three months ended March 31:
