5.Explain how the term V is obtained.
6.Explain how the fluctuations value C is used to adjust the current valuation V.
7.Explain the time period which is used in Equation 1.
8.Describe an alternative method to Equation 1 to adjust for the effects of inflation.

Task 3:
Calculate the fluctuation value C using the following data:
 Prices for the contract were tendered in June 2013
 The current claim related to the period June 2015
 The value V of the current claim = $100,000.00

Hint: Data for Equation 1 do can be sourced from Stats NZ. For older statistic you may need to review the archive
