tal amount of all of the rewards for HITs and assignments
								that have not yet been completed. This includes the reward for each
								unclaimed assignment for HITs that have not yet expired, each
								assignment in progress, and each submitted assignment that has not
								yet been approved or rejected. This is an estimate, because it is
								possible that not all of a HIT's assignments will be completed
								before the HIT expires. The amount is given in U.S. dollars. </p>
