The Company’s pension plans use fair value as the market-related value of plan assets and recognize 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 in net periodic (benefit) cost as of the plan measurement date, which is the same as the fiscal year end of the Company. Net actuarial gains or losses that are less than 10% of the thresholds noted above are accounted for as part of the accumulated other comprehensive loss.

Effective December 31, 2014, the Company terminated the eligibility of employees ages 55 - 64 years old to enter into the Post-retirement Medical Plan.
