• Misconception exists that because the 1st payment is less than the time loss rate, you can pay the entire balance of $10,703.02 (the down payment and remaining balance) at closure instead of paying the down payment and creating a monthly payment schedule.

• Though the balance remaining after the down payment is less than the time loss rate, you still have to complete a schedule and pay the balance plus interest on the scheduled payment date.

Her claim closed on 12/1/08 with a permanent partial impairment of the right arm as follows: 32% impairment of the arm at any point below the deltoid insertion to below the elbow joint at the insertion of the biceps tendon.
