Employee Benefit Plans [Abstract] |
Employee Benefit Plans | 13. Employee Benefit Plans The Corporation sponsors a contributory defined contribution Section 401(k) plan in which substantially all employees participate. The plan permits employees to make pre-tax contributions which are matched by the Corporation at 100% for every 1% contributed up to three percent then 50% for every 1% contributed up to the next four percent in total of the employee’s compensation. The Corporation’s contributions were $397, $385, and $350 in 2012, 2011, and 2010, respectively. Profit sharing contributions to this plan, based on current year compensation, are 6 percent of total compensation plus 5.7 percent of the compensation in excess of $110. The Corporation recognized profit sharing expense of $783, $667, and $641 in 2012, 2011, and 2010 respectively. The Corporation has adopted a non-qualified supplemental executive retirement plan (“SERP”) for certain executives to compensate those executive participants in the Corporation’s retirement plan whose benefits are limited by compensation limitations under current tax law. The SERP is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the SERP are payable from the general assets of the Corporation. At December 31, 2012 and 2011, obligations of $3,792 and $3,276, respectively, were included in other liabilities for this plan. Expenses related to this plan were $728 in 2012, $647 in 2011, and $227 in 2010. The Corporation has established a Survivor Benefit Plan for the benefit of outside directors. The purpose of the plan is to provide life insurance benefits to beneficiaries of the Corporation’s directors who at the time of their death are participants in the plan. The plan is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the plan are payable from the general assets of the Corporation. At December 31, 2012 and 2011, obligations of $813 and $686, respectively, were included in other liabilities for this plan. Expenses related to this plan were $127 in 2012, $106 in 2011, and $21 in 2010. The Corporation has an unfunded post retirement benefits plan which provides certain health care benefits for retired employees who have reached the age of 60 and retired with 30 years of service. Benefits are provided for these retired employees and their qualifying dependents from the age of 60 through the age of 65. The following table sets forth the change in the benefit obligation of the plan as of and for the years ended December 31, 2012, 2011, and 2010:
|  | 2012 |  |  | 2011 |  |  | 2010 |
Benefit obligation at beginning of year |  | $ | 1,674 |  |  | $ | 1,073 |  |  | $ | 783 |
Interest cost |  |  | 69 |  |  |  | 56 |  |  |  | 43 |
Service cost |  |  | 88 |  |  |  | 49 |  |  |  | 34 |
Actual claim expense |  |  | (184 | ) |  |  | (262 | ) |  |  | (167 | )
Actuarial loss |  |  | 577 |  |  |  | 758 |  |  |  | 380 |
Benefit obligation at end of year |  | $ | 2,224 |  |  | $ | 1,674 |  |  | $ | 1,073 |
Amounts recognized in accumulated other comprehensive income at December 31, 2012 and 2011 consist of:
|  | 2012 |  |  | 2011 |
Net actuarial loss |  | $ | (1,502 | ) |  | $ | (958 | )
Transition obligation |  |  | (7 | ) |  |  | (14 | )
|  |  | (1,509 | ) |  |  | (972 | )
Tax effect |  |  | 528 |  |  |  | 340 |
|  | $ | (981 | ) |  | $ | (632 | )
The accumulated benefit obligation was $2,224 and $1,674 at December 31, 2012 and 2011, respectively. The following table sets forth the components of net periodic benefit cost and other amounts recognized in other comprehensive income:
|  | 2012 |  |  | 2011 |  |  | 2010 |
Service cost |  | $ | 88 |  |  | $ | 49 |  |  | $ | 34 |
Interest cost |  |  | 69 |  |  |  | 56 |  |  |  | 43 |
Net amortization of transition obligation and actuarial loss |  |  | 41 |  |  |  | 11 |  |  |  | 3 |
Net periodic benefit cost |  |  | 198 |  |  |  | 116 |  |  |  | 80 |
Net loss |  |  | 578 |  |  |  | 758 |  |  |  | 380 |
Amortization of loss |  |  | (34 | ) |  |  | (4 | ) |  |  | 4 |
Amortization of transition obligation |  |  | (7 | ) |  |  | (7 | ) |  |  | (7 | )
Total recognized in other comprehensive income |  |  | 537 |  |  |  | 747 |  |  |  | 377 |
Total recognized in net periodic benefit cost and other comprehensive income |  | $ | 735 |  |  | $ | 863 |  |  | $ | 457 |
The estimated net loss and transition obligation that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next fiscal year are $54 and $7, respectively. The weighted average discount rate used to calculate net periodic benefit cost was 4.29% in 2012, 5.50% in 2011, and 5.75% in 2010. The weighted average rate used to calculate accrued benefit obligations was 3.88% in 2012, 4.29% in 2011, and 5.50% in 2010. The health care cost trend rate used to measure the expected costs of benefits is 5.0% for 2013 and thereafter. A one percent increase in the health care trend rates would result in an increase of $289 in the benefit obligation as of December 31, 2012, and would increase the service and interest costs by $43 in future periods. A similar one percent decrease in health care trend rates would result in a decrease of $247 and $34 in the benefit obligation and services and interest costs, respectively, at December 31, 2012.
