DEFINING KEY TERMS THAT CAME UP REPEATEDLY IN THE HEARING During the April 30, 2009, NAIC hearing on credit-based insurance scoring (CBIS), discussion turned from the present economic climate to social propriety of CBIS. “Discrimination,” “proxy,” “disparate impact,” “proxy effect,” “unfair discrimination,” and “disproportionate impact” – there are many concepts that arise in this context. While they may on the surface seem like subtle differences, it is crucial for all those involved in discussing the policy and legal issues to have a common vocabulary on this important aspect of the issue. We caution that no statement included herein may be taken out of context. This is a summary, not exhaustive treatment, of the subject, which we reserve the right to supplement at any time. Discrimination / Intentional (“Overt”) Discrimination Definition A definition for the commonly understood meaning of discrimination is found at dictionary.com: “treatment or consideration of, or making a distinction in favor of or against, a person or thing based on the group, class, or category to which that person or thing belongs rather than on individual merit.” Discussion Because intentional (“overt”) discrimination occurs when a person is treated a particular way based on a prohibited factor and because insurers do not use race, a prohibited factor, in underwriting and rating, intentional (‘overt”) discrimination is not relevant to the CBIS discussion. Proxy Definition A “proxy” is typically understood as one factor substituting for another. In the context of this discussion, the relevant questions would be does credit or CBIS stand in the place of a prohibited factor like race or is one able to determine a person’s race by seeing her insurance score? The FTC framed this by providing that whether CBIS is a proxy for race, ethnicity or income hinges on whether the scores are predictive within those groups. Here is the FTC’s conclusion on the issue: “In short, because scores do predict risk within racial, ethnic, and income groups, they do not act solely as a proxy for those characteristics.” “Proxy” has been part of the landscape of this discussion since the term was used in Section 215 of the Fair and Accurate Credit Transactions Act of 2003 (FACTA),1 requiring a study of the effects of credit scores and credit-based insurance scores on availability and affordability of financial products. Discussion The FTC found that the “relationship between scores and claims risk remains strong when controls for race, ethnicity, and neighborhood income are included in the statistical models of risk.” Disproportionate Impact / Statistical Difference / Differential Effect Definition 1 Section 215 is included as an Exhibit to these comments. Specifically, (a)(3) provides in part for a study of “the extent to which, if any, the use of credit scoring models, credit scores, and credit-based insurance impact on the availability and affordability of credit and insurance to the extent information is currently available or is available through proxies, by geography, income, ethnicity, race, color, religion, national origin, age, sex, marital status, and creed, including the extent to which the consideration or lack of consideration of certain factors by credit scoring systems could result in negative or differential treatment of protected classes under the Equal Credit Opportunity Act…” (Emphasis added.)

“Disproportionate impact” refers to the pure statistical impact differences. Some may also refer to this as “disparate impact,” but a full disparate impact analysis goes further and it may simplify the discussion to refer to the statistical-only difference as “disproportionate impact.” The Federal Reserve study refers to this concept as “differential effect.”2 Discussion This is not a legal or actuarial concept. Indeed, it governs the sale of no product or service in our economy. Proxy Effect Definition The term “proxy effect” differs from “proxy.” It is not in FACTA nor is it commonly used in statistical, legal, or actuarial fields. However, it does appear in the FTC’s auto study. It seems to mean that even if there is no “proxy” – because a factor is risk related – there may be a “proxy effect” if there are score differences that cannot be explained by a factor other than race. This concept was not discussed in the parallel Federal Reserve study. Discussion In order to model correctly, the FTC needed some way of capturing the geographic risk. The insurers that provided the data for the FTC Study each used different territorial schemes. So the territory used for rating the policies would not work. While all the insurers could provide zip code, zip codes would be almost impossible for the FTC to use as is because there are too many to model. FTC needed to use one single scheme across all states to capture the geographic risk. In other words the FTC needed a means to group the zip codes into a reasonable number of groups with similar loss propensities. The solution required the insurers to report additional property damage data and that property damage data would be used to group the zip codes. This solution assumed that all the coverages behaved geographically very similar to property damage. It appears that assumption was incorrect. Unfortunately, the FTC attempted to measure a “proxy effect” with more precision than its database would allow. Such a precise measurement would require the ability to precisely control the study for all non-racial factors such as age, gender, marital status, tenure, mileage, and geographical location of the insured. The FTC’s controls for these factors were less than ideal, and as such the FTC cannot say with any degree of certainty that it did in fact find even a small proxy effect. For the property damage liability coverage where the FTC had the best controls for geographic risk, the FTC found no proxy effect. If the FTC had been able to control for geographic risk as accurately for all coverages as it did for the property damage liability coverage, all hints of a proxy effect would likely have disappeared. Unfair Discrimination Definition The definition of “unfairly discriminatory” is tied to accurately measuring risk, meaning that rates must be cost-based and treat policyholders with equal risks equally. The standard of not being “unfairly discriminatory” is the very foundation for insurance regulation. It consumes the field in areas where a 2 See page 54 of the Federal Reserve Board August 2007 Report to the Congress on Credit Scoring and Its effects on the Availability and Affordability of Credit.

State legislature does not otherwise deem a particular factor to be “unfairly discriminatory” via a public policy mandate. Discussion Every study of CBIS has found a correlation between credit-based insurance score and risk. Each of these studies has substantiated that there is actuarial justification. State insurance laws, and indeed the principles underpinning property and casualty insurance pricing, rely on actuarial science to determine rates that most accurately measure loss potential. Actuarial science accomplishes this task by finding relationships between factors and risk of loss and then allocating costs accordingly. This is the essence of risk-based pricing. Importantly, to disregard the predictive value of a factor (1) ignores actuarial support; (2) results in better risks subsidizing worse risks; and (3) moves closer to a one-size-fits-all approach in direct conflict with risk classification standards. Pricing programs of most insurers depend on making distinctions based upon a number of different factors. All things being equal, the one who reflects a worse risk based on this difference will pay more. To explain, the process of risk classification involves segmenting groups of individuals expected to have similar costs. The use of more segments makes for a more granular approach in which actuaries can more finely hone their review of an individual in order to more accurately create class plans and measure risk potential. When there are a greater number of risk levels and pricing variations, insureds are placed with others with a more similar risk profile, which results in a more accurate, and therefore by definition fairer price. Also, using this granular methodology, insurers are better able to offer coverage to people they might have otherwise declined. Disparate Impact Analysis Definition The legal theory of disparate impact is applied on a case-by-case basis. It allows a plaintiff with no evidence of intentional discrimination to sue under certain civil rights laws3 by alleging that a business practice, such as an employment policy, disproportionately disadvantages the members of a protected group. But because business practices that produce disparate effects occur all the time in the workplace and throughout society in the complete absence of any unlawful discrimination, Congress and the courts have taken care to carve out an important and express exception to liability – the “business necessity” rule, which recognizes that even when a policy results in a disparate / disproportionate impact, that policy is permissible if it is reasonably related to a legitimate business objective and the plaintiff cannot prove that an equally effective alternative exists to achieve that objective. The business necessity rule ensures that businesses are not unfairly punished for adopting a policy that serves a legitimate business purpose, but may happen to result in a disproportionate impact. Discussion There is disagreement over whether the disparate impact legal theory would be applicable to cases involving certain personal lines coverages. Regardless, even assuming the theory can be applied and that a valid and statistically relevant disproportionate impact is found, legitimate business needs are served by CBIS and no ready and equally accurate alternative is available.

3 Disparate impact theory was originally developed in the context of employment discrimination claims brought under Title VII of the Civil Rights Act of 1964. See Griggs v. Duke Power Co., 401 U.S. 424 (1971). The “business necessity” rule was codified by Congress twenty years later in the Civil Rights Act of 1991, 42 U.S.C. Sec, 2000e-2(k)(1)(A). The rule is also applicable for claims arising under the Fair Housing Act.

Error! Unknown document property name.

A comprehensive actuarial analysis of 2.7 million auto insurance policies across the United States conclusively demonstrated that credit-based insurance scores are linked to the propensity for loss. The massive multivariate study showed that insurance-based credit scores consistently ranked among the top two or three most important risk factors for all components of auto insurance coverage: bodily injury liability, personal injury protection, medical payments, property damage liability, collision and comprehensive.4 Improving the accuracy of risk assessment and pricing plainly qualifies as a legitimate business objective. Consideration of a consumer’s credit history allows insurers to estimate a consumer’s risk of loss with greater accuracy, with in turn allows the underwriter to set premiums at a level that more appropriately reflects that risk. Credit scoring is reasonably necessary to achieve an important business objective and is therefore consistent with business necessity. Broadening the availability of insurance coverage is an additional, and unquestionably legitimate, business purpose served by CBIS. The use of CBIS increases competition by allowing a low-cost but effective underwriting or rating tool. The FTC has agreed with this conclusion in its own study: “After trying a variety of approaches, the FTC was not able to develop an alternative credit-based insurance scoring model that would continue to predict risk effectively, yet decrease the differences in scores on average among racial and ethnic groups.”5

EXHIBIT 1

FAIR AND ACCURATE CREDIT TRANSACTIONS ACT OF 2003

SEC. 215. STUDY OF EFFECTS OF CREDIT SCORES AND CREDIT-BASED INSURANCE SCORES ON AVAILABILITY AND AFFORDABILITY OF FINANCIAL PRODUCTS.

(a) STUDY REQUIRED.—The Commission and the Board, in consultation with the Office of Fair Housing and Equal Opportunity of the Department of Housing and Urban Development, shall conduct a study of—

(1) the effects of the use of credit scores and credit-based insurance scores on the

availability and affordability of financial products and services, including credit cards, mortgages, auto loans and property and casualty insurance;

(2) the statistical relationship, utilizing multivariate analysis that controls for prohibited factors under the Equal Credit Opportunity Act and other known factors, between credit scores and credit-based insurance scores and the quantifiable risks and the actual losses experienced by businesses;

(3) the extent to which, if any, the use of credit scoring models, credit scores, and credit-based insurance impact on the availability and affordability of credit and insurance to the extent information is currently available or is available through proxies, by geography, income, ethnicity, race, color, religion, national origin, age, sex, marital status, and creed, including the extent to which the consideration or lack of consideration of certain factors by credit scoring systems could result in negative or differential treatment of protected classes under the Equal Credit Opportunity Act, and the extent to which, if any, the use of underwriting systems relying on these models could achieve comparable results through the use of factors with less negative impact; and

(4) the extent to which credit scoring systems are used by businesses, the factors considered by such systems, and the effects of variables which are not considered by such systems.

(b) PUBIC PARTICIPATION.—The Commission shall seek public input about the prescribed

methodology and research design of the study described in subsection (a), including from relevant Federal regulators, State insurance regulators, community, civil rights, consumer, and housing groups.

(c) REPORT REQUIRED.--

(1) IN GENERAL.—Before the end of the 24-month period beginning on the date of

enactment of this Act, the Commission shall submit a detailed report on the study conducted pursuant to subsection (a) to the Committee on Financial Services of the House of Representatives and the Committee on Banking, Housing, and Urban Affairs of the Senate.

(2) CONTENTS OF REPORT.—The report submitted under paragraph (1) shall include the findings and conclusions of the Commission, recommendations to address specific areas of concerns addressed in the study, and recommendations for legislative or administrative action that the Commission may determine to be necessary to ensure that credit and credit-based insurance scores are used appropriately and fairly to avoid negative effects.

www.aiadc.org October 24, 2008 Commissioner John Morrison, Chair National Association of Insurance Commissioners Market Regulation and Consumer Affairs (D) Committee 2301 McGee Street Suite 800 Kansas City, Missouri 64108-2662 Re: “Review of the Use of Credit-Based Insurance Scoring By Insurers” - AIA Review of August 26, 2008 Draft Dear Commissioner Morrison: The American Insurance Association (AIA) appreciates the opportunity to comment on the National Association of Insurance Commissioner’s August 26 draft report “Review of the Use of Credit-Based Insurance Scoring By Insurers.” Although relatively thorough in the number of reports analyzed, in tone and in content the report often takes a one-sided approach to credit-based insurance scoring (CBIS). An NAIC report on CBIS should take care to offer a balanced and unbiased approach, even when presenting a comprehensive consumer perspective. This would include describing the various viewpoints – consumers, insurers, academics, regulators - in the ongoing debate. Moving forward, any NAIC report should be accurate, objective, grounded in the law, recognize progress in the debate and be void of faulty presumptions.

Real consumers, policyholders and voters had the opportunity to comment directly on credit-based insurance scoring in Oregon via their vote and turned down a proposed ban by a margin of 2-1 (2006 election). For a consumer perspective, the report should dig deeper than critiques made by some special interest consumer advocacy groups. Most of the consumer viewpoints and footnotes in the report are attributed to one source (from the Center for Economic Justice). That is a disservice to the NAIC, its staff, the consumers they aim to serve and the insurers that they regulate (those same insurers that ultimately fund NAIC activities). The NAIC should consider other resources, such as complaint numbers from their own departments, insurers who operate each day on product, price and service using CBIS, vendors who create CBIS, agencies that supply data to create CBIS and the countless others in this arena. The NAIC and individual state insurance departments have access to more complete and objective information sources, such as the number and nature of consumer policyholder complaints received about CBIS, trends over time, the ratio of complaints to numbers of auto and homeowners policies, and comparisons to complaints and inquiries received on other matters. The NAIC report on CBIS should include an inventory and analysis of data on CBIS-related policyholder complaints.

In the states in which AIA has recently testified on CBIS legislative proposals, the commissioners have provided the number of CBIS related consumer complaints, and they are in the few dozen annually, an impressive performance considering the millions of personal lines transactions in those states. This lack of real complaints is especially significant because under federal law a specific notice is sent to each consumer that has experienced an adverse action as a result of the use of CBIS. The NAIC report also gives scant attention to one salient fact: the auto and homeowners markets (outside of catastrophe prone areas) are functioning quite well with generally stable prices and good availability. A major reason for this is wide use of CBIS, which allows more accurate pricing, reducing premiums for many, if not most, policyholders. In addition, availability, as demonstrated by historically low residual market populations, has improved because insurers now can insure virtually all risks because they can, with CBIS, reliably price them.

Importantly, to be credible the overarching review which comprises the first half of the report must achieve greater balance by a broader analysis of consumer attitudes, insurance department data and consumer feedback, insurer viewpoints and testimony on the efficacy of credit scoring, and studies conducted by academics. Specific concerns with and suggestions for the report follow, with the draft language on the left and AIA’s comments presented on the right:

In closing, if it is going to be issued, the paper should be significantly revised. As currently drafted, it is not only internally inconsistent, but in some places, it lacks objectivity. In addition, it includes rhetoric containing novel concepts and theories that have little or no relationship to the law that regulators must implement. The vast majority of state legislatures and/or regulators have already enacted balanced CBIS requirements. Not only is no further state or NAIC research needed, but today regulators already have all the tools they need to address any concerns. Sincerely, Jeffrey Junkas , David Snyder, David Unnewehr, Director of Public Affairs Vice President & Assistant Vice President Midwest Region Assistant General Counsel Policy Development & Research Enclosure
