The main processes in Modeling include:
DAC (Deferred Acquisition Cost): GAAP accounting requires the matching of expenses to revenues. Large upfront expenses required to sell life and annuity products must be amortized over the life of the products based on expected future profits. Each year actuaries in Modeling are responsible for calculating the amount of the DAC write off or write up, the remaining DAC balance, and expected future profits.
AOM (Actuarial Opinion and Memorandum): State insurance regulators require that insurance companies hold sufficient reserves. In other words, regulators want to ensure that companies will be able to pay all the current and future claims owed to their policyholders. AOM is the process life actuaries perform to provide regulators with this information. The present value of a company’s assets must be greater than the present value of its liabilities. The present values are reviewed under a variety of assumptions about how interest rates will behave in the future.
RBC C-3: Risk-based capital is a method developed by the National Association of Insurance Commissions (NAIC) to measure the minimum amount of capital that an insurance company needs to support its operations. The measurement sets capital requirements to reflect the degree of risk taken by the insurer. Many elements of RBC are factor-based, but the C-3 (interest rate risk) component is determined using a company’s models. Allstate Financial sets the C-3 capital component as the percentage of statutory reserves required to maintain solvency at the 95th conditional tail expectation of a stochastically generated set of economic market scenarios.
Economic Capital: Economic Capital is a new application of our corporate actuarial modeling software. Economic Capital can be defined as the excess of the market value of the assets over the fair value of liabilities required to ensure that our obligations can be satisfied at a given level of risk tolerance, over a specified time horizon. Stochastic scenarios are used to capture the economic risks inherent in the insurance business, including: market risk (interest rates and equities), credit risk, mortality risk, lapse risk, and operational risk. Economic Capital has many uses including determining the "right" level of capital, allocating capital back to the product lines, performance measurement, assisting with rating agency discussions, risk management, and product pricing.
Model Maintenance and Enhancements: In between delivering on the above process, the Modeling Unit focuses its efforts on maintaining and enhancing the corporate model. This includes working with different areas of the company to revisit assumptions, adding new products and new product features, converting a few "older" models not on the current platform, automating portions of the modeling process, and developing new model capabilities such as duration-matching and stochastic investment credit migration. In addition, time is spent looking at potential future applications of the corporate model, such as principles-based reserves, fair value accounting, and economic performance measures.
