Linden Lab Official:How are group dividends calculated?

Group dividends are divided equally amongst all group members who have the Pay group liabilities and receive group dividends ability associated with their role. Likewise, all group liabilities are also spread evenly between group members with this ability.

If nobody in the group has this ability, then group liabilities and dividends are paid to the group's owner (the group's owner always has all abilities).

Exception:

• If there are no enabled accounts in the group that have the Pay group liabilities and receive group dividends ability, then liabilities and dividends will be spread evenly between group members.

Tip: If you are planning to join a Linden owned group, check to see if that group participates inworld with liabilities and dividends before joining.
