Feldblum.Ratings

Rating agencies are supposed to provide reliable financial strength ratings for insurers. So people were very P-O'd in 2008-09 when highly rated mortgage-backed securities went up in smoke. A.M. Best, Moody's, and S&P screwed up big-time, and legislation now requires rating agencies to disclose details of their method. FeldBlum's papers are always well-written.

(We'll be using the term Rating Agency frequently in this wiki article so let's use the abbreviation RA.)

Based on past exams, the main things you need to know (in rough order of importance) are:

• the importance of RAs to insurers [Hint: USE]
• identify & describe the capital models used by the 3 main rating agencies
• miscellaneous facts about interactive rating and rating agencies
• the notion of RA as regulator - are the rating agencies effectively acting as regulators of the insurance industry

Intro

The paper is quite long, 31 pages, but you don't have to read all of it in detail. Feldblum is a great writer, and it's good to become familiar with him.

As an aside, he wrote an interesting opinion piece on the actuarial exam process versus the CFA designation. It's from way back in 2000, but here's the link if you want some bedtime reading: FeldBlum's Opinion. And here's another interesting opinion piece on the exam process from Gil Student. (Just something to think about.) My personal experience after I left academia in 1995 to start an actuarial carrer was that I took exams for 3 years and was half-way to fellowship. Then I met my significant other and decided to stop taking exams altogether. (I already had my Ph.D. in math and I just didn't feel like studying for exams anymore.) I did, however, continue reading syllabus papers but it was different because I was reading for understanding versus memorization. One of my first projects was coding a suite of reserving software, but that's a story for another day. It wasn't until almost 20 years later that I decided to return and get my ACAS. I got so frustrated with the existing study guide for exam 6 that I invented my own system. And that's the origin story of BattleActs.

Anyway, back to the task at hand:

Question: why do we bother with financial strength ratings at all

• for policyholders:

   - financial strength ratings help buyers assess an insurer's ability to pay claims (some buyers MUST place business with highly rated reinsurers)

• for P&C insurers:

   - a high rating can help insurers get business

   - a financial strength rating by a rating agency can uncover potential solvency issues without involving a regulator

Ok, now we know the why but we also need to know the who and the how

Question: who does financial strength ratings

A.M. Best:

   - has the most experience with financial strength ratings of insurers

Moody's:

   - focuses more on debt ratings (versus overall financial strength ratings)

S&P (Standard & Poor's):

   - focuses more on debt ratings (versus overall financial strength ratings)

Question: how are financial strength ratings done

• All 3 agencies use something called interactive rating as an overall methodology (discussed later) but they differ in their specific rating or capital model (also discussed later.)

Let's finish up the intro with a couple of key points regarding the reliability of rating agencies:

Question: how do rating agencies ensure consistency across insurers

1. standard information-gathering & assessment guidelines
2. ratings are related to economic capital
3. analysis & final rating should be issued by separate bodies.

It's important to realize that rating agencies are not perfect. If they were, we never would have had the financial crisis of 2007-2008.

Question: describe shortcomings of rating agencies

conflict of interest

   - rating agencies are paid by the companies they rate (how dumb is that?!!!)

history of unreliability

   - rating agencies have given high ratings to companies that then went bankrupt. (Example: Enron Scandal)

Interactive Rating

In the previous section we learned that rating agencies use a process called interactive rating when evaluating the financial strength of an insurer. It is a comprehensive qualitative & quantitative analysis.

Question: describe the 5 steps of the interactive rating process [Hint: RM-PDP]

Research: by ratings analysts (insurer submits proprietary info)

Meeting: between rating analysts & insurer's senior management for presentations

Proposal: the rating analyst leader proposes a rating (insurer may submit further info)

Decision: by ratings committee

Publication: to public & fee-paying subscribers

You can see that these 5 steps should indeed provide a comprehensive evaluation of the company. This is part of the reason for placing a high degree of trust in rating agencies. But this methodology also has drawbacks: [Hint: ITE]

Intrusive: insurer must provide detailed operational info

Time-consuming: requires extensive meetings with senior management

Expensive: insurer must pay for rating agencies to do the interactive ratings

Question: if interactive ratings are such a royal pain in the ass, why do insurers bother with them [Hint: USE]

Unrated insurers: agents are wary of unrated insurers

Solvency assessment: 3rd parties such as regulators or investors may rely on a rating agency's assessment

Efficiency: agents, underwriters, regulators don't have the expertise to evaluate the financial strength of an insurer

An example where a rating is important is reinsurance because if downgraded to below investment grade, a reinsurer may not be able to renew its treaties and thus lose business.

Capital Models

The interactive rating includes a lot of qualitative information-gathering. Let's now look at their quantitative capital models on a high level.

Rating Agency	General Description of Method	Detailed Description	Other
A.M. Best	EPD (Expected Policyholder Deficit)	EPD = $P / $V 1	SELECTION: choose required capital so that EPD = 1%
Moody's	stochastic cash flows to model economic capital	repeated simulations of loss distributions of separate risks	TIME HORIZON: project cash flows until liabilities are settled
Std & Poor's	PB (principles-based) models & ERM 2 practices	evaluate insurer's (ERM, internal capital model)	RATING: weighted avg of (S&P, insurer) capital assessment

¹ $P = pure premium for treaty, $V = market value of reserves

² ERM is Enterprise Risk Management

There are several old exam problems in this next quiz that ask you compare state evaluations of capital adequacy (usually RBC) with evaluations by rating agencies. There are good problems because they tie together different parts of the syllabus.

Appendix D: Exercises

Feldblum has included exercises in this reading. If this were a higher ranked reading, I would recommend that you do these exercises as they would be good exam questions. But I think there is only a low probability of any of these exercises appearing on your exam. Take a look at Exercise 1, but beyond that, only if you have extra time before the exam. (This is unlikely!!)
