Termination of Qualified Pension Plan, description	On April 2, 2014, our Board of Directors approved a resolution to terminate the Qualified Pension Plan. The termination of the Qualified Pension Plan is subject to the Internal Revenue Service’s (“IRS”) determination that the Qualified Pension Plan is qualified on termination. We believe it will take 18 to 24 months to finalize the complete termination of the Qualified Pension Plan after obtaining IRS approval. We have not yet received IRS approval that the Qualified Pension Plan is qualified on termination. Additionally, we have amended the Qualified Pension Plan to provide that participants are 100 percent vested in their accrued benefits as of the effective date of the plan termination, to adopt a new standard for disability benefits that will apply when the plan’s assets are distributed due to the termination, to add a lump sum distribution for employees and terminated vested participants who are not in payment status when Qualified Pension Plan assets are distributed due to the termination and to make certain other conforming amendments to the Qualified Pension Plan to comply with applicable laws that may be required by the IRS or may be deemed necessary or advisable to improve the administration of the Qualified Pension Plan or facilitate its termination and liquidation.
