This section shall be liberally construed to ensure that the insurer shall establish and maintain reserves which place a sound value on its liabilities and which make a good and sufficient provision for all unpaid obligations and contingencies.
IBNR reserve = W X IBNR based on actual experience X A + (1-W) X expected IBNR X A where W is weighting factor varying from zero to 1.0 giving appropriate credibility to actual experience, and A is an adjustment factor, if any, to reflect changes in claim costs due to changing utilization, exposure, inflation, benefit changes, or any other appropriate adjustments.
