Pension benefits are based on formulas that reflect the employees' years of service and compensation during their employment period. The pension expense recognized by the Company is determined using certain assumptions, including the expected long-term rate of return on plan assets, the interest factor implied by the discount rate and the expected rate of compensation increases.TWC uses a December 31 measurement date for the pension plans.
