PURPOSE AND OPERATION OF RETROSPECTIVE RATING PLANS

• Organizations seeking greater risk retention while maintaining insurance often consider using retrospective rating plans as a sophisticated risk financing tool.

• These plans offer a flexible and cost-sensitive alternative means of insurance pricing, thus requiring knowledge of the specific losses they cover and how the premiums are dynamically determined over the policy period.

Purpose of Retrospective Rating Plans

• The main purpose is to adjust the premium of guaranteed-cost insurance retrospectively (after the policy period ends) based on the actual current losses of the insured organization during that period.

• Unlike traditional methods relying primarily on aggregated industry loss experience for pricing, retrospective rating utilizes the organization’s own loss history from the current policy period to set its final premium, making the insured partly self-insured.

• Insurers cover losses exceeding specified amounts (loss limits or aggregate loss limits), thereby acting as a crucial risk transfer mechanism for catastrophic or unpredictable events.

• The design inherently promotes robust risk control and loss prevention programs, rewarding organizations that successfully minimize losses with significantly lower premiums and providing a direct financial incentive for safety.

Lines of Business for Retrospective Rating Plans

• Commonly used for:

  • Workers compensation: Often chosen due to the high frequency and relatively predictable nature of claims.

  • Auto liability: Similar to workers' compensation, can have predictable frequency based on fleet size and operations.

  • General liability: Covers a broad range of exposures, and predictability depends on the organization's specific operations.

  • Auto physical damage

  • Crime

  • Glass loss exposures

• A single retrospective rating plan can be structured to cover multiple lines of business or loss exposures, providing a consolidated approach to risk financing.

• Typically used for financing low- to medium-severity, high-frequency losses that are generally somewhat predictable in aggregate, allowing for a more accurate reflection of the insured's actual risk profile.

Characteristics of Losses Covered

• High predictability (meaning losses occur with some regularity and within an expected range) aligns well with retrospective rating plans, as they adapt premiums based on incurred losses during the policy period. This allows the insured to bear a portion of predictable losses while transferring unpredictable severe losses.

• Organizations generally unsuited for retrospective plans often have:

  • Small premium sizes: The administrative complexity and costs often outweigh the potential savings for smaller accounts.

  • Wide fluctuations in annual premium amounts: If loss experience is highly volatile and unpredictable, retrospective rating can lead to budgeting difficulties.

  • Financial instability: The requirement for collateral and the potential for significant premium adjustments necessitate a strong financial position.

Premium Determination

• The insured organization initially pays a deposit premium, followed by subsequent adjustments.

• The insurer uses the collected premiums for various costs, including ultimate claim payments, taxes, market loadings, administrative overhead, and profit margins.

• Premiums are directly and dynamically influenced by the types and amounts of losses incurred during the policy term, with periodic adjustments (e.g., 18, 30, 42 months after policy inception) to reflect developing loss experience.

Comparison with Guaranteed-Cost Insurance

• Guaranteed Cost Insurance: The premium is static and fixed at the beginning of the policy period, independent of the actual losses incurred by the insured during that period.

• Retrospective Rating Plan: In contrast, an initial premium (deposit premium) is paid, but the final premium can be significantly adjusted post-policy based on the actual, unpredicted, or developing loss experience of the insured. This requires the insured to assume more risk but offers the potential for substantial savings.

CALCULATING A RETROSPECTIVE RATING PLAN PREMIUM

• A retrospective rating premium is calculated using an agreed-upon formula that addresses several key components, ensuring a fair allocation of costs and risks:

  • Standard Premium: This is a base premium computed using authorized industry rates applicable to the organization’s estimated exposures for the policy period, before any retrospective adjustments. It serves as the starting point for calculating all other components.

  • Computed using:

    $\text{Manual Premium} = \text{Number of Exposure Units} \times \text{Manual Rate}$

    $\text{Standard Premium} = \text{Manual Premium} \times \text{Experience Modification Factor}$

  • Basic Premium: This component covers the insurer's fixed costs, including acquisition costs (e.g., commissions), administrative costs (e.g., underwriting, policy issuance), insurer profit margin, and an insurance charge. The insurance charge reflects the premium collected by the insurer for assuming the risk that the actual losses might exceed the maximum premium specified in the plan.

  • Converted Losses: This product represents the incurred losses adjusted to include allocated loss adjustment expenses (ALAE), which are the costs directly associated with investigating, defending, and settling a claim. It is calculated as:

    $\text{Converted Losses} = \text{Loss Conversion Factor} \times \text{Incurred Losses}$

  • The Loss Conversion Factor accounts for expenses directly related to claim settlement and adjustment not included in the basic premium.

  • Excess Loss Premium: This component compensates the insurer for the risk of losses exceeding a pre-set per-occurrence or aggregate limit. It effectively funds the portion of the losses that the insurer bears above the client's self-retained level. Calculated as:

    $\text{Excess Loss Premium} = \text{Standard Premium} \times \text{Excess Loss Premium Factor} \times \text{Loss Conversion Factor}$

  • Tax Multiplier: This factor accounts for various state taxes, assessments, and surcharges that apply to the insurance premium. It ensures these mandatory regulatory charges are passed through to the insured. Calculated as:

    $\text{Tax Multiplier} = 1 + \text{Tax Rate}$

• The retrospective rating premium for the policy period is ultimately calculated by the following formula:

  $\text{Retrospective Premium} = [(\text{Basic Premium} \times \text{Standard Premium}) + (\text{Converted Losses} \times \text{Excess Loss Premium Factor})] \times \text{Tax Multiplier}$

• Premiums are adjusted subject to pre-agreed maximum and minimum amounts (known as the maximum and minimum retrospective premium), which define the risk tolerance of both the insured and the insurer. The final premium will never fall outside these bounds.

Numerical Example

• Consider Canston Manufacturing, contemplating a retrospective rating plan:

  • Policy limit: $1,000,000</p></li><li><p>Standard premium:$700,000

  • Basic premium: 20% of standard premium ($140,000)</p></li><li><p>Loss conversion factor: 1.10 (to cover ALAE)</p></li><li><p>Loss limit:$500,000 per occurrence (losses above this amount are paid by the insurer, influencing the excess loss premium factor)

  • Tax Multiplier: 1.04

• Using the comprehensive retrospective rating premium formula combined with various incurred loss scenarios allows for the calculation of different potential premium amounts, demonstrating the variability and potential cost savings or increases.

TYPES OF RETROSPECTIVE RATING PLANS

Incurred Loss Retrospective Rating Plan

• In this plan, insureds pay premiums based on incurred losses, which include not only paid losses but also estimated outstanding (reserved) losses and associated loss adjustment expenses. Claims are valued at specific intervals (e.g., 18, 30, 42 months), and premiums are adjusted accordingly.

• This denotes a relative lack of immediate cash flow benefit from funds retained as loss reserves, as these reserves remain with the insurer, impacting the insured's working capital.

Paid Loss Retrospective Rating Plan

• In this system, the insured pays an initial deposit premium and gradually repays the insurer only as the insurer makes actual payments on claims. This can significantly improve the insured's cash flow, as funds are not required until claims are fully settled.

• Generally incurs lower deposit premiums compared to incurred loss plans, enhancing cash flow, but introduces greater complexity due to the need for security guarantees.

• The complexity increases substantially due to the necessity for security guarantees (collateral), usually required via letters of credit, surety bonds, or trust accounts, adding administrative difficulty and cost to the insured.

Comparison Considerations

• Organizations should not automatically default to choosing paid loss structures over incurred loss plans without a thorough comparative analysis. This analysis should scrutinize financial terms, potential interest earnings on retained funds, administrative burden, collateral costs, the timing of cash flows, and overall cash flow implications. The choice depends heavily on the organization's financial strength, liquidity, and risk appetite.

ADMINISTRATION OF RETROSPECTIVE RATING PLANS

• Administered predominantly by the insurer, with key responsibilities including claims adjustment, reserving, premium recalculations, and regulatory filings. The insurer manages the underwriting and actuarial aspects.

• The insured primarily focuses on timely premium payments, maintaining effective loss control programs, and potentially arranging required securities for future payouts to guarantee the insurer's solvency.

Collateral Requirements

• Collateral is crucial for securing the insurer against the credit risk of unpaid future premiums, especially in paid loss plans where the insurer is paying claims upfront. Forms could be letters of credit, surety bonds, or trust accounts, often warranting significant management resources and involving substantial fees and administrative overhead for the insured.

Financial Accounting Implications

• Organizations must meticulously recognize premium liabilities for incurred losses at reporting dates, including potential Incurred But Not Reported (IBNR) amounts, which can significantly affect balance sheets, income statements, and key financial ratios (e.g., profitability, solvency).

Tax Considerations

• A critical aspect is recognizing tax deductions on premiums based on either cash payments or incurred losses (depending on the accounting method), influencing the timing and amount of tax liabilities and deductions. This can significantly influence the selection and structuring of a plan.

Exit Strategy

• Retrospective plans can generally be terminated by either party, albeit with potential penalties for early cancellation. It is vital to understand the run-off provisions, which dictate how outstanding losses will be handled and how final premium adjustments will be made after termination, ensuring a clear process for closing out the policy.

ADVANTAGES AND DISADVANTAGES OF RETROSPECTIVE RATING PLANS

Advantages

1. Long-term Cost Effectiveness: Offers the potential for significantly reduced insurance costs in the long run, particularly for organizations with effective loss control programs, as costs more closely align with actual loss experience rather than industry averages. This can lead to substantial savings over time compared to guaranteed-cost plans.

2. Encourages Loss Control: Establishes a direct and powerful financial connection between loss reduction efforts and tangible premium savings. This incentivizes management to invest in safety, risk mitigation, and claims management, driving down overall risk costs.

3. Stability in Financial Planning: With appropriate design (e.g., well-defined maximum/minimum premiums) and a stable loss history, these plans can provide predictable earnings and cash flow, as the organization has more control over its ultimate insurance expenditure.

Disadvantages

1. Financial Planning Challenges: Poorly designed plans or those without adequate maximum premium caps can create significant uncertainty in premium adjustments due to unexpected loss events, severely hindering accurate financial budgeting and forecasting.

2. Higher Administrative Burdens: Especially prevalent with paid loss plans, attributed to the need for more comprehensive security measures (collateral), more frequent premium adjustments, and detailed tracking of claim payments, all demanding greater internal resources.

3. Increased Taxes and Fees: The premium components must represent sufficient amounts to cover various state and federal taxes, assessments, and surcharges. Additionally, costs associated with collateral (e.g., letter of credit fees) add to the overall expense, potentially increasing the total cost beyond simply claims and insurer overhead.

SELECTING A RETROSPECTIVE RATING PLAN

• In selecting a retrospective rating plan, the following steps should be meticulously evaluated:

  1. Determine coverages for inclusion: Identify all lines of business (e.g., workers' compensation, general liability) that will be part of the unified retrospective rating program, considering their loss characteristics and alignment with the organization's risk retention strategy.

  2. Assess limits applicable to the retrospective plan: Establish appropriate per-occurrence and aggregate loss limits that define the amount of self-retained risk versus transferred risk to the insurer. This involves analyzing historical loss data and the organization's risk tolerance.

  3. Analyze the necessity for a loss limitation: Evaluate whether specific large losses or catastrophic events should be capped (e.g., per claim limit) to prevent a single severe incident from disproportionately impacting the retrospective premium, providing more stability.

  4. Evaluate maximum vs. minimum premium factors relative to potential loss scenarios: Determine the upper (maximum) and lower (minimum) bounds of the potential retrospective premium. The maximum premium protects the insured from catastrophic losses, while the minimum premium guarantees a baseline profit for the insurer. This evaluation requires stress-testing various loss scenarios to understand the financial implications.

Case Study Example: Etchley Manufacturing

• Etchley Manufacturing's risk financing strategy was meticulously analyzed against guaranteed-cost options. This involved utilizing a systematic approach to identify optimal coverage areas for inclusion in a retrospective plan, establishing suitable loss limits, and exhaustively evaluating various maximum and minimum premium combinations. The objective was to identify the plan that offered the most advantageous balance between risk retention, cost control, and financial predictability for the organization's specific operational context and loss profile.
