ALAE

Allocated Loss Adjustment Expenses (ALAE)

Allocated Loss Adjustment Expenses (ALAE) are loss adjustment expenses that can be directly attributed to the investigation, defense, or settlement of a specific individual claim.

Common Examples of ALAE

• Fees paid to outside attorneys for legal defense.
• Court costs and deposition expenses.
• Fees for independent adjusters or experts hired for a specific claim.
• Medical examinations required to verify injury severity.

Aggregation & Estimation Methods

ALAE is typically aggregated on an Accident Year (AY) basis to match the corresponding losses. Actuaries estimate ultimate ALAE using three main methods:

1. Direct Development Method

• Process: Construct a triangle of historical ALAE payments or reported ALAE, and apply standard chain ladder development techniques to project ultimate ALAE.
• Pros/Cons: Simple and independent of losses, but can be highly volatile if ALAE data is thin.

2. Multiplicative ALAE-to-Loss Ratio Method

• Assumption: ALAE scales proportionally with the size/severity of the loss.
• Process:
  1. Construct a triangle of historical ratios: $\frac{\text{ALAE}}{\text{Loss}}$ (either paid or reported).
  2. Develop these ratios to ultimate using ratio development factors.
  3. Apply the selected ultimate ALAE-to-Loss ratio to the estimated ultimate losses: $$\text{Ultimate ALAE} = \text{Ultimate Losses} \times \text{Ultimate }\left(\frac{\text{ALAE}}{\text{Loss}}\right)\text{ Ratio}$$
• Pros/Cons: Standard industry practice. Leverages the stability of the loss triangle.

3. Additive ALAE-to-Loss Ratio Method

• Assumption: ALAE is fixed per claim or exposure rather than proportional to the loss size.
• Process: Estimate ultimate ALAE by developing the ratio of ALAE to claim counts or exposures, or by adding a fixed dollar load to the pure premium.
• Pros/Cons: Useful for high-frequency, low-severity lines of business where defense costs are flat regardless of claim size.
