Hint

The only cells affected by commutation are PY-2 at 36 months.

Net Paid

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Step 1

Use this formula below to find the net paid triangle before commutation

    net paid = (net ceded) x (1-qs%) / qs%

Step 2

subtract the commutation price from the appropriate cell from Step 1 to find the net paid after commutation

Net Ultimate

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Step 1

Use the formula below to find the net ultimate triangle before commutation

    net ultimate = (net paid) + (net reserve)

Step 2

Use the formula below to recalculate the appropriate cell from Step 1

net ultimate after commutation = (net paid after commutation) + (net reserve before commutation) + (ceded reserve before commutation)
