The Company’s pension plans use fair value as the market-related value of plan assets and recognize actuarial gains or losses in other comprehensive income/(loss).  Net actuarial gains or losses in excess of ten percent (10%) of the greater of the market-related value of plan assets or of the plans’ projected benefit obligation will be recognized in net periodic (benefit) cost as of the plan measurement date, which is the same as the fiscal year end of the Company.
