| Bid B | $0.50 | 50% |
| Bid C | $0.30 | 30% |
| Bid D | $0.10 | 50% |
Assigning - Starting from the highest bid, each bid is assigned an SoV up to their maximum SoV, until all 100% of SoV has been assigned.
| Example | Bid amount | Max. SoV | Assigned SoV |

Costing - After all 100% of SoV has been assigned, the bid amount of the next bid is taken as the cost
