Steven          Markle          2200      120.0
Peter           Tucker          10000     145.0
David           Bernstein       9500      145.0
Peter           Hall            9000      145.0
Christopher     Olsen           8000      145.0
Nanette         Cambrault       7500      145.0
Oliver          Tuvault         7000      145.0
