The Kerper Bowron Method

Contract-level accounting for service contracts. The KB Method replaces aggregate earning curves with month-by-month expected cash flows for every individual contract — built from point-of-sale data and aligned with Solvency II, IFRS 17, and ASC 606.

The Method

From aggregate curves to contract-level truth

For more than forty years, the service contract industry has earned premium and estimated losses with aggregate earning curves — one backward-looking shape applied to an entire block of business. The Kerper Bowron Method works from the opposite direction: it prices the future one contract at a time.

Industry practice

Aggregate earning curves and block-level reserving built on industry averages and summary experience, with subjective assumptions layered on top.

Slow to adapt when the mix of business shifts, difficult to provide credible results to stakeholders, and structurally unable to satisfy modern accounting standards simultaneously.

The KB Method

A precise, month-by-month stream of expected claim and cancellation payments for every individual contract, generated from point-of-sale data alone.

Auditable, contract-specific accounting that adapts to actual experience as it emerges — and rolls up cleanly into reserves, earnings, liabilities, and asset estimates.

  1. Start at the point of sale

    Term, mileage, coverage, deductible, vehicle profile, price, and additional factors — data every seller already captures.

  2. Model exposure probabilistically

    A probabilistic exposure base for each month of the contract replaces the traditional expected-miles assumption.

  3. Project every cash flow

    Advanced statistical models produce expected claim and cancellation payments, month by month, contract by contract. Projected claims are also adjusted for trend, seasonality, and other factors.

  4. Earn with the Earned Contract formula

    Revenue, reserves, and liabilities follow directly from the projected cash-flow stream — and update as experience develops.

Watch

The KB Method, explained

Regulatory Alignment

One calculation, three frameworks

Existing aggregate methods cannot satisfy modern accounting and solvency standards simultaneously while keeping contract-level granularity. The KB Method was built to meet all three at once.

Solvency IIArticle 77 · European Union

The first method mathematically demonstrated to exactly match the EU’s “ideal equation” — the probability-weighted best estimate of future cash flows — for finite, predictable risks, a result previously considered unattainable for insurance exposures.

IFRS 17International Accounting

Contract-level expected cash flows align directly with IFRS 17’s measurement model, producing consistent, auditable estimates for insurers and reinsurers reporting internationally.

ASC 606U.S. GAAP

For non-insurance entities — administrators, sellers, and obligors — revenue recognition follows expected cash flows by contract, automating alignment and reducing audit risk and administrative burden.

    Kerper & Bowron founded

    John Kerper, FSA, MAAA, and Lee Bowron, ACAS, MAAA, open the firm in Birmingham and begin developing exposure-based techniques for service contracts — starting with two components: exposure development and loss projection.

  2. 2007

    Foundation paper published by the CAS

    “An Exposure Based Approach to Automobile Warranty Ratemaking and Reserving” appears in the Casualty Actuarial Society Forum, introducing the exposure-based framework the KB Method builds on.

  3. 2025

    Patent filed

    U.S. Provisional Patent Application No. 63/858,053 is filed, with related company Irish Trinity LLC developing the intellectual property.

  4. Feb 2026

    Peer-reviewed publication

    The paper is accepted and published in Risks (MDPI) — the first formal academic validation of the approach.

  5. May 2026

    National recognition; implementations underway

    Featured in Business Alabama and announced via Business Wire as administrators, financial institutions, and insurance professionals move toward 2026 implementations.

    Birmingham Business Journal feature

    The Birmingham Business Journal covers the method as pilot-project evaluations with potential clients get underway.

Applications

Built for VSCs. Ready for every service contract.

The method applies to virtually all contracts covering repair, maintenance, or accidental damage — and its contract-level precision opens financial applications well beyond reserving.

Vehicle service contracts

The core application: precise claim and cancellation streams for VSC books, including constantly shifting mixes of term, mileage, and coverage.

Phones, appliances & home systems

Extends naturally to phone protection plans, appliance warranties, and home system coverage across the global market.

Lending & capital

Quantifying the gap between projected losses and required reserves with actuarial certainty unlocks compliant lending capital inside existing dealer-owned reinsurance structures.

Pricing & product development

Contract-level visibility feeds directly into sharper pricing, product design, and capital deployment decisions.

Cancellation forecasting

Accurate cancel liabilities and forecasts support better budgeting for dealers, administrators, and obligors.

Customer lifetime value

The same expected cash-flow stream extends to customer lifetime value analysis, as developed in the published paper.

FAQ

Common questions

What is the KB Method in one sentence?

A patent-pending actuarial and accounting method that produces a precise, month-by-month stream of expected claim and cancellation payments for every individual service contract, using only point-of-sale data. This method has additional applications in collateralization and fundamentally changes how the service contract/manufacturer warranty is financially modeled, reserved, and capitalized.

How is it different from traditional earning curves?

Earning curves apply one aggregate, backward-looking shape to an entire block of business. The KB Method builds the estimate from the bottom up — a probabilistic exposure base and advanced statistical models generate contract-specific projections that adapt to actual experience rather than industry averages.

What data does it require?

Only data captured at the point of sale — term, mileage, coverage, deductible, vehicle profile, price, and similar factors — plus the claim and cancellation experience that emerges over time.

Which accounting and regulatory standards does it support?

The method aligns with Solvency II, IFRS 17, and ASC 606 simultaneously, and is the first method mathematically demonstrated to exactly match Solvency II’s ideal equation (Article 77) for finite, predictable risks. The method is also compliant with U.S. GAAP and NAIC standards.

Has the method been independently validated?

Yes. The full paper was peer-reviewed and published in Risks (MDPI) in 2026. A U.S. provisional patent application (No. 63/858,053) has been filed.
