The Pentegra Plan’s Employer Identification Number is 13-5645888 and the Plan Number is 333. The Pentegra Plan operates as a multiemployer plan for accounting purposes and as a multiple employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. There are no collective bargaining agreements in place that require contributions to the Pentegra Plan. The Pentegra Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra Plan, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. If the Company chooses to stop participating in the Pentegra Plan, it may be required to pay an amount based on the underfunded status of the Pentegra Plan which is referred to as a withdrawal liability. The Company froze the benefits in the Pentegra Plan effective March 1, 2003. Full-time employees of the Company who had attained at least 21 years of age and completed one year of service were eligible to participate in the Pentegra Plan. In addition, employees who would have been eligible after March 1, 2003 are not eligible to participate. No further benefits will accrue subsequent to the freeze, and the freeze does not reduce the benefits accrued up to the date of the freeze. Calculations to determine full-funding status are made annually by the third-party plan administrator as of June 30. At June 30, 2012 and 2011, the funding target, which is defined as the market value of plan assets divided by the plan liabilities, of the Company’s portion of the Pentegra Plan was 83.2% and 80.9%, respectively, funded. Total contributions by all employer participants in the Pentegra Plan, as reported on Form 5500, totaled $299.7 million and $203.6 million, respectively, for the plan years ended June 30, 2011 and 2010. The Company’s contributions to the Pentegra Plan totaled $595,000 and $605,000, respectively, for the years ended December 31, 2012 and 2011 and do not represent more than 5% of the total contributions made by all employer participants in the Pentegra Plan. Given the current interest rate environment, the lower asset valuations, and other factors impacting the operations of the Pentegra Plan, it is likely that our future funding obligations will increase. Pension expense for the years ended December 31, 2012, 2011, and 2010 was $602,000, $302,000, and $115,000, respectively.
