Rebasing
From ACT Wiki
1. Index numbers.
Rebasing can refer to either:
- changing the weights in an index, such as an inflation index,
- changing the reference period of an index number series.
The weights and the reference period may be changed at the same time.
2. UK tax - capital gains.
In relation to assets acquired before 31 March 1982, rebasing restated the value as of 31 March 1982.
