Accounting for employee pension obligations requires the use of actuarial techniques to make a reliable estimate of the amount of benefit that employees have earned in return for their services in the current and prior period. The actuarial assumptions are based on management’s best estimates of the variables that will determine the ultimate cost of providing post-employment benefits. Variations in these assumptions could cause material adjustments in future years, if it is determined that the actual experience differed from the estimate.
