Plan assets investment objective description It is our policy to diversify the investment of the plan’s assets to reduce the risk of large losses.  Progress toward achieving performance objectives is reviewed quarterly by management with particular attention directed to reviewing performance relative to the risks. Each investment vehicle is expected to perform in the top 75% of its peer group over the most recent 12-month period and the top 50% of its peer group over five-to ten-year periods and the majority of the rolling three-year periods.  Performance of the pension funds, individual investment managers, actuarial assumptions, and other attributes of the pension plan are reviewed at least annually with the Company’s Board of Directors.
