  conjunction with the Qualified Defined Benefit Retirement Plan. The strategy implemented by the trustee of the Qualified Defined 
  Benefit Retirement Plan is to achieve long-term objectives and invest the pension assets in accordance with ERISA and fiduciary 
  standards. The long-term primary objectives are to provide for a reasonable amount of long-term capital, without undue exposure 
  to risk; to protect the Qualified Defined Benefit Retirement Plan assets from erosion of purchasing power; and to provide investment 
  results that meet or exceed the actuarially assumed long-term rate of return. The expected long-term rate of return on assets 
  assumption was developed by considering the historical returns and the future expectations for returns of each asset class as well as 
  the target asset allocation of the pension portfolio.
