Do you intend to use the 10yr or 1yr govt bond rate to set the rate of return? What arrangements are planned to incorporate the fluctuations in these rates that occur: over the last 40yrs the 10yr rate has fluctuated between 18% and 2%? Can you guarantee those arrangements will match the current rate rather than reflecting last year's rate? I note that up till mid year Govt was still using 8% for one of its capital return rates.
