Purging calculation based on the normalisation method
| Months | Normalisation of shares [No. of share × (A + B)/B] | Share months | Purging amount |
|---|---|---|---|
| April | 2 × (2 + 1)/2 = 3 | 3 × 12 = 36 | 36 × 0.2 = 7.2 |
| May | 2 × (2 + 1)/2 = 3 | 3 × 11 = 33 | 33 × 0.2 = 6.6 |
| June | −2 × (2 + 1)/2 = −3 | −3 × 10 = −30 | 30 × 0.2 = −6.0 |
| August | 4 | 4 × 8 = 32 | 32 × 0.2 = 6.4 |
| December | −2 | −2 × 4 = −8 | 8 × 0.2 = −1.6 |
| Total | 63 | 12.6 | |
