NR 756.07(7) (7) Inflation rate. The rates of inflation applied to cost estimates approved by the department in previous years shall be derived from the most recent implicit price deflator for gross domestic product published by the U.S. department of commerce in its Survey of Current Business.

Future earnings shall be calculated based on a projected rate of return equal to the projected rate of inflation plus one percent, or the department may require that, when estimating future earnings on these accounts, the weighted average rate of return of the investments held in the account be used for a period of time not to exceed the weighted average maturity of the investments held in the account rounded to the nearest whole year. Earnings for years beyond the weighted average maturity of the investments in the account shall be calculated based on a projected rate of return equal to the projected rate of inflation plus one percent.
