Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure | Employee Retirement and Deferred Compensation Plans Salary Deferral Savings Plans We maintain salary deferral savings plans covering substantially all employees. We recognized an expense, net of plan forfeitures, with respect to the plans of $7.8 million, $6.4 million and $5.0 million for the fiscal years ended October 31, 2014, 2013, and 2012, respectively. Deferred Compensation Plan We have an unfunded, nonqualified deferred compensation plan that permits eligible employees to defer a portion of their compensation. The deferred compensation, together with certain of our contributions, earns various rates of return depending upon when the compensation was deferred and the length of time that it has been deferred. A portion of the deferred compensation and interest earned may be forfeited by a participant if he or she elects to withdraw the compensation prior to the end of the deferral period. We accrued $20.4 million at October 31, 2014 and 2013 for our obligations under the plan. Defined Benefit Retirement Plans We have two unfunded defined benefit retirement plans. Retirement benefits generally vest when the participant has completed 15 or 20 of service with us and reaches normal retirement age (age 62). Unrecognized prior service costs are being amortized over the period from the date participants enter the plans until their interests are fully vested. We used a 3.55%, 4.01%, and 3.07% discount rate in our calculation of the present value of our projected benefit obligations at October 31, 2014, 2013, and 2012, respectively. The rates represent the approximate long-term investment rate at October 31 of the fiscal year for which the present value was calculated. Information related to the plans is based on actuarial information calculated as of October 31, 2014, 2013 and 2012. Information related to our retirement plans for each of the fiscal years ended October 31, 2014, 2013, and 2012, is as follows (amounts in thousands):
