By: Amanda Roth To refine your risk-based pricing another level, it is important to analyze where your tiers are set and determine if they are set appropriately.  (We find many of the regulators / examiners are looking for this next level of analysis.) This analysis begins with the results of the scoring model validation.  Not only will the distributions from that analysis determine if the score can predict between good and delinquent accounts, but it will also highlight which score ranges have similar delinquency rates, allowing you to group your tiers together appropriately.  After all, you do not want to have applicants with a 1 percent chance of delinquency priced the same as someone with an 8 percent chance of delinquency.  By reviewing the interval delinquency rates as well as the odds ratios, you should be able to determine where a significant enough difference occurs to warrant different pricing. You will increase the opportunity for portfolio profitability through this analysis, as you are reducing the likelihood that higher risk applicants are receiving lower pricing.  As expected, the overall risk management of the portfolio will increase when a proper risk-based pricing program is developed. In my next post we will look the final level of validation which does provide insight into pricing for profitability.  

By: Amanda Roth As discussed earlier, the validation of a risk based-pricing program can mean several different things. Let’s break these options down. The first option is to complete a validation of the scoring model being used to set the pricing for your program. This is the most basic validation of the program, and does not guarantee any insight on loan profitability expectations. A validation of this nature will help you to determine if the score being used is actually helping to determine the risk level of an applicant. This analysis is completed by using a snapshot of new booked loans received during a period of time usually 18–24 months prior to the current period. It is extremely important to view only the new booked loans taken during the time period and the score they received at the time of application. By maintaining this specific population only, you will ensure the analysis is truly indicative of the predictive nature of your score at the time you make the decision and apply the recommended risk-base pricing. By analyzing the distribution of good accounts vs. the delinquent accounts, you can determine if the score being used is truly able to separate these groups. Without acceptable separation, it would be difficult to make any decisions based on the score models, especially risk-based pricing. Although beneficial in determining whether you are using the appropriate scoring models for pricing, this analysis does not provide insight into whether your risk-based pricing program is set up correctly or not. Please join me next time to take a look at another option for this analysis.

In a recent presentation conducted by The Tower Group, “2010 Top 10 Business Drivers, Strategic Responses, and IT Initiatives in Bank Cards,” the conversation covered many of the challenges facing the credit card business in 2010.  When discussing the shift from “what it was," to “what it is now” for many issues in the card industry, one specific point caught my attention – the perception of unused credit lines – and the change in approach from lenders encouraging balance load-up to the perception that unused credit lines now represent unknown vulnerability to lenders. Using market intelligence assets at Experian, I thought I would take a closer look at some of the corresponding data credit score profile trends to see what color I could add to this insight. Here is what I found: • Total unused bankcard limits have decreased by $750 billion from Q3 2008 to Q3 2009 • By risk segment, the largest decline in unused limits has been within the VantageScore® credit score A consumer – the super prime consumer – where unused limits have dropped by $420 billion • More than 82 percent of unused limits reside with VantageScore® credit score A and B consumers – the super-prime and prime consumer segments So what does this mean to risk management today? If you subscribe to the approach that unused limits now represent unknown vulnerability, then this exposure does not reside with traditional “risky” consumers, rather it resides with consumers usually considered to be the least risky. So this is good news, right? Well, maybe not. Vintage analysis of recent credit trends shows that vulnerability within the top score tiers might represent more risk than one would suspect. Delinquency trends for VantageScore® credit score A and B consumers within recent vintages (2006 through 2008) show deteriorating rates of delinquency from each year’s vintage to the next. Despite a shift in loan origination volumes towards this group, the performance of recent prime and super-prime originations shows deterioration and underperformance against historical patterns. If The Tower Group’s read on the market is correct, and unused credit now represents vulnerability and not opportunity, it would be wise for lenders to reconsider where and how yesterday’s opportunity has become today’s risk.
