The Company matches 100% of the first 3% of the employee's compensation contributed. The Company then matches 75% of the next 2% of the employee's compensation contributed.

Employees Stock Ownership Plan (“ESOP”)—In 1996, the Company established an ESOP, which is open to all eligible employees who have completed one year of service working at least 1,000 hours. The Company’s contributions to the ESOP represent an annual profit-sharing bonus paid to employees. Such contributions and available forfeitures are allocated to active employees based on the percentage that their compensation represents of the total compensation of eligible employees. The Company purchased 20,081, 0 and 11,638 shares of its common stock for the ESOP in 2013, 2012 and 2011, respectively. The Company’s contribution and expense to the ESOP was approximately $57 thousand, $250 thousand and $100 thousand for 2013, 2012 and 2011, respectively. As of December 31, 2013 and 2012, the ESOP held 160,938 and 150,455 shares, and there were no unallocated shares. On an annual basis, the Board determines the amount to contribute to the ESOP as a profit sharing bonus. Upon termination, plan participants are paid in cash or retain their vested balance in the ESOP. During 2013, 2012 and 2011, shares withdrawn from the ESOP by participants who terminated their employment with the Company amounted to 9,354, 1,903 and 22,053 shares, respectively. During 2013, 2012 and 2011, no shares were added to the ESOP plan from dividend reinvestments.
