When calculating an interim impairment payment amount under subsection 75(2) of the MRCA, the Commission must allocate a lifestyle rating using the following methodology:

Step 1:
Obtain the lifestyle rating for all conditions previously determined.

Step 2:
Work out the lifestyle rating for all conditions (including the current condition in respect of which a determination has not been made) using:

  1. the top of the shaded area for impairment points between 0 and 15; or
  2. in any other case — the bottom of the shaded area.

Step 3:
Use the highest of the lifestyle ratings from steps 1 and 2 to calculate the interim PI payment

This method of assessment for interim permanent impairment is not to be used when subsection 75(4) of the Act applies. The methods as outlined in Section 5.16.3.2 should then be used.
