Defined Benefit Plan, Assumptions Used Calculating Net Periodic Benefit Cost, Discount Rate   4.14% 4.36%  
Defined Benefit Plan, Assumptions Used in Calculation, Description   For the SERP, the discount rate assumption used to measure the postretirement benefit obligations is set by reference to a certain hypothetical AA-rated corporate bond spot-rate yield curve constructed by our actuary, Aon Hewitt (“Aon”). This yield curve was constructed from the underlying bond price and yield data collected as of the Plan’s measurement date and is represented by a series of annualized, individual discount rates with durations ranging from six months to seventy-five years. Aon then applies the yield curve to the actuarially projected cash flow patterns to derive the appropriate discount rate.
