We currently provide retirement benefits to our domestic employees through a defined contribution plan. Through 2005, domestic employees were covered primarily by noncontributory plans, funded by company contributions to trust funds held for the sole benefit of employees. We amended the defined benefit plans, freezing and ceasing future benefits as of December 31, 2005. Certain transitional benefits were provided to certain participants, but ceased accruing when the plan became inactive on December 31, 2010.

The projected benefit obligation of our qualified defined benefit pension plan exceeded the fair value of plan assets by $165,393 at December 31, 2011, the measurement date. On June 25, 2010, the federal government passed the Preservation of Access to Care for Medicare Beneficiaries and Pension Relief Act of 2010 (“the Pension Relief Act”) which is designed to provide relief from the funding requirements of the Pension Protection Act of 2006. The Pension Relief Act provides opportunities for plan sponsors to extend the time over which plan deficits may be funded, up to 15 years, subject to certain limitations including offsets for excess compensation and extraordinary dividends. With the benefit of the Pension Relief Act, our remaining funding requirements for 2012 under the Employee Retirement Income Security Act of 1974 (“ERISA”) were approximately $9,000 as of June 30, 2012. On July 6, 2012, the federal government passed the Moving Ahead for Progress in the 21st Century Act (“MAP-21”), which includes provisions designed to provide additional funding relief. MAP-21 allows plan sponsors to extend the period over which average interest rates are calculated, from two years to 25 years, for use in discounting pension liabilities and determining funding requirements. We are currently assessing the extent to which MAP-21 will affect our remaining funding requirements for 2012 and future years under ERISA.

If the relief provided by the federal government expires or is no longer applicable to our qualified pension plan, or if there is downward pressure on the asset values of the plan, or if the present value of the projected benefit obligation of the plan increases, as would occur in the event of a decrease in the discount rate used to measure the obligation, it would necessitate significantly increased funding of the plan in the future.
