How this is calculated

Worked example, using the default values

  1. Define the reinsurance layer
    Layer = Attachment xs Limit
    $5,000,000 xs $10,000,000 (exhaustion at $15,000,000) = Layer: $5,000,000 to $15,000,000
  2. Calculate LEV at attachment and exhaustion
    LEV(d) = (θ/(α−1)) × [1 − (θ/(θ+d))^(α−1)]
    LEV(5,000,000) = $1,861,910, LEV(15,000,000) = $2,628,011 = Layer factor = 38.31%
  3. Compute technical premium (expected ceded loss)
    Technical Premium = LEV(A+L) − LEV(A)
    $2,628,011 − $1,861,910 = $766,101
  4. Apply risk load
    Risk Load = Technical Premium × Risk Load %
    $766,101 × 15% = $114,915
  5. Apply brokerage
    Brokerage = (Technical + Risk Load) × Brokerage %
    $881,016 × 10% = $88,102
  6. Total premium and rate on line
    Rate on Line = Total Premium / Limit × 100
    $969,118 / $10,000,000 = 9.69% ROL, 10.3 yr payback
