Spread loot among the interests of a variety of Archetypes, if possible. Everyone loves nuyen. Claudia Tyger will get a share of most windfalls, but no more than the player characters, since she does not accompany them on the runs.

G'wan, buy yourself an Earthdawn rulebook and find out what's happening.
