The present value of the retirement and long-service leave obligations depends on a number of factors that are determined on an actuarial basis using a number of assumptions. Two key assumptions used in calculating this liablity include the discount rate (7.5%) and the salary inflation factor (3%). Any changes in these assumptions will impact on the carrying amount of the liability.

In determining the appropriate discount rate, LINZ considered the interest rates on New Zealand government bonds which have terms to maturity that match, as closely to possible, the estimated future cash outflows. The salary inflation factor has been determined after considering historical salary inflation patterns and after obtaining advice from an independent actuary.
