    • Selecting and classifying insurance risks.

  • Claims Management:

    • Determining amounts to pay in claims and managing risk.

  • Rate Making:

    • Determining a price to charge for the insurance product.

  • Investing:

    • Selecting investment mediums for insurance company assets.

  • Accounting:

    • Reporting financial data to regulators and others.

  • Reinsurance:

    • Diversifying insurance risk through reinsurers.

  • Other Services:

    • IT, data analytics, and human resources.

Production/Distribution

  • Corresponds to the sales or marketing function in an industrial firm.

  • Referred to as “production” because insurance is intangible; a product doesn’t exist until it is sold.

  • Covered in the Organizational Forms chapter.

  • Direct vs Indirect Marketing.

  • Other production-related functions include:

    • Finding insurers with the right “appetite.”

    • Conducting marketing research.

    • Advertising.

    • Risk management services.

Underwriting

  • Definition: All activities necessary to select risks offered to the insurer in such a manner that general company objectives are fulfilled.

  • Primary Objective:

    • To ensure that the applicant accepted will not have a loss experience that is very different from assumptions made when rates were determined.

  • To achieve this, underwriting must block adverse selection.

  • Adverse Selection: The tendency for individuals with higher risk to buy more insurance.

Underwriting: Life Insurance

  • Underwriting in life insurance is performed by home or regional office personnel, rarely by agents.

  • Company underwriters use:

    • Medical reports from the physician who examined the applicant.

    • Information from the agent prepared by an outside agency.

    • Advice from the company’s own medical advisor.

Underwriting: Property and Liability Insurance

  • In property-liability insurance, agents can sometimes make binding decisions in the field, known as field underwriting or “AGENT”.

  • When agents have “binding authority” or “the pen,” insurers must guard against agent bias.

Underwriting Careers

  • As underwriters progress, they do less “day-to-day” underwriting.

  • They make decisions on the most complex risks.

  • Often involved in insuring new risks.

  • Many ULM graduates work as underwriters in the surplus lines.

  • No two risks are the same, thus, no two days are the same.

Claims Management: Responsibilities

  • Responsibilities include:

    • Ascertaining the validity of written proofs of loss.

    • Investigating the scene of the loss.

    • Estimating the amount of the loss.

    • Interpreting and applying the terms of the policy in loss situations.

    • Approving payment of the claim.

Claims Management: Life vs. Property

  • Technology significantly impacts property adjusting with tools like drones and satellites.

  • More extensive in property-liability insurance than in life insurance due to:

    • Higher frequency of losses.

    • Predominance of partial losses.

    • Uncertainty of the amount of loss in individual cases.

Claims Management: Types of Adjusters

  • Company Adjusters (Staff Adjusters): Salaried staff employees of the insurer.

  • Independent Adjusters: Engage where an insurer lacks sufficient volume to employ a staff adjuster.

  • Public Adjusters: Specialize in adjusting and represent policyholders in dealings with insurers.

  • Risk Management and Loss Control:

    • In large insurance and brokerage organizations, risk managers are very involved in this process (e.g., WC Claims and safety requirements).

    • May involve lawyers and investigators.

Rate Making

  • Process:

    • Collecting statistics on past frequency and severity of loss.

    • Applying these statistics to selected exposure units.

    • Works closely with underwriting to assign rates to selected classes.

  • Extremely technical in most lines of insurance, especially property and liability.

  • Based substantially on historical loss data and numerous rating factors such as:

    • Mortality rates according to age, sex, smoking/drinking habits, and occupation.

  • Less complicated in life insurance.

Rate Making: Who and What

  • Actuaries: Highly trained mathematicians/statisticians who use loss histories and other data to determine appropriate rates for insurance.

  • Insurance Premium: Designed to cover two major costs: the expected loss and the cost of doing business, known as the pure premium and the loading.

Rate Making: Elements

  • Rate per unit of coverage:

    • Gross Premium: Includes both the pure premium and the loading.

    • The amount of the premium expected to go towards covering the loss. - Pure Premium (PP):

    • The percentage of the gross premium expected to pay for expenses and underwriting costs.

    • Includes underwriting costs, commissions, taxes, and overhead.

    • Loading (LP): The additional percentage added to cover operational costs.

Rate Making: Gross Premium Equation

  • extGP=extPP+extLPimesextGPext{GP} = ext{PP} + ext{LP} imes ext{GP}

Rate Making: Gross Premium Equation (Continued)

  • extPP+extLP(extGP)=extGPext{PP} + ext{LP}( ext{GP}) = ext{GP}

  • extPP=extGPextLP(extGP)ext{PP} = ext{GP} - ext{LP}( ext{GP})

  • extPP=extGP(1extLP)ext{PP} = ext{GP}(1 - ext{LP})

  • racextPP(1extLP)=extGPrac{ ext{PP}}{(1- ext{LP})} = ext{GP}

Rate Making: Gross Premium Calculation Example

  • Example:

    • Pure Premium (PP) = $1.50.

    • Expense Loading Percentage (LP) = 33%.

    • Calculation:

    • extGrossPremium=racextPP(1extLP)ext{Gross Premium} = rac{ ext{PP}}{(1- ext{LP})}

    • extGrossPremium=rac1.50(10.33)=rac1.500.67ext{Gross Premium} = rac{1.50}{(1-0.33)} = rac{1.50}{0.67}

    • extGrossPremium2.24ext{Gross Premium} ≈ 2.24

  • $2.24 is the amount they need to charge to break even (if loss and expense assumptions are correct).

Rate Making: Insurance Company’s Rules and State Laws

  • Rates must be:

    • Adequate: Must be sufficient to pay claims, preventing company insolvency.

    • Not Excessive: Usually not an issue due to competition.

    • Not Unfairly Discriminatory: Must reasonably reflect the riskiness of the exposure; some factors cannot legally be included (e.g., race, religion, ethnicity).

Rate Making: Methods of Rating

  • Manual or Class Rating (Pure Method): Sets rates uniformly for each exposure unit within predetermined classes.

  • Loss Ratio Method:

    • extLossRatio=racextLossesextPremiumsext{Loss Ratio} = rac{ ext{Losses}}{ ext{Premiums}}

    • Measures “performance” of insured risks (typically around 70%).

    • If actual loss ratio is higher than expected, rates need to be increased.

  • Individual or Merit Rating Method: Reflects individual risk features and hazards, also known as “judgment rating.”

  • Combination Method: Uses a mix of manual and merit rating across various lines of insurance.

Investing

  • Insurance premiums are typically paid in advance for periods of 6 months to a year.

  • Advance payment leads to the necessity to invest funds wisely to remain competitive.

  • Investment income plays a vital role in insurers' success.

    • In life insurance: Solvency relies on earning a minimum guaranteed return on assets.

    • In property and liability insurance: Investment income has historically made insurers profitable, offsetting underwriting losses.

Accounting

  • Given the highly regulated and complex financial nature of insurance, a special set of accounting rules apply.

  • Statutory Accounting Principles (SAP): Form the basis of financial filings insurers must submit to state regulators.

    • The aim is similar to standard accounting: to record, classify, and interpret financial data to guide management in policy-making.

Reinsurance: Terms

  • Primary Insurer (aka “Cedent”):

    • The company that originally writes the business and buys reinsurance to transfer some of the risk.

  • Reinsurer: The company assuming the risk from a primary insurer.

  • Verb: To Cede: To purchase a reinsurance contract, thereby transferring some risk.

  • Noun: A Cession: The act of acquiring a reinsurance contract; involves transferring risk to a reinsurer.

Reinsurance: Types

  • Facultative: Reinsuring ONE underlying policy.

  • Treaty: Reinsuring an entire book of business.

Reinsurance: Facultative vs. Treaty

  • Facultative: E.g., reinsuring the Mercedes Benz Superdome’s property.

  • Treaty: E.g., reinsuring all long-haul trucking liability in LA, TX, and AR.

  • Another example: All homeowners' property policies written in South Louisiana.

Reinsurance: Pro Rata: Percentage Sharing of Risk

  • Example with 40% Pro Rata Sharing of Premiums and Losses:

    • Reinsurer: 40%; Insurer: 60%.

Reinsurance: Pro Rata Examples

  • Cedent: $75,000.00; Claim: $125,000 Loss.

    • Loss borne by Cedent: $75,000.00.

    • Loss borne by Reinsurer: $50,000.00.

    • Cedent: $24,000.00; Claim: $40,000 Loss.

    • Loss borne by Reinsurer: $16,000.00.

    • Cedent: $54,000.00; Claim: $90,000 Loss.

    • Loss borne by Reinsurer: $36,000.00.

Reinsurance: Excess of Loss

  • Scenarios depicted for various loss amounts:

    • $125,000 Loss.

    • $40,000 Loss.

    • $90,000 Loss.

  • Visual aids can illustrate how a $50,000 Excess of Loss Treaty responds in terms of cedent retention and reinforcer roles.

Reinsurer Functions

  • Increasing Individual Risk Capacity: Allows insurers to write larger risks.

  • Making Books Look Better: Can help mitigate appearances of loss for growing companies.

  • Stabilizing Losses (Loss Ratio): Caps retained losses and can be utilized for catastrophic loss caps.

  • Retiring an Insured Book: Insurers can reinsure most of their risks.
