DefaultA debtor is in default at the moment when it is probable that he will not repay his obligations in a proper

and timely manner, or when at least one repayment of principal is more than 90 days past due.

Slide 20

Credit risk – Measurement of credit risk (CNB)

Since 2005, banks have been able to use the portfolio-based approach (statistically based) to calculate provisions (allowances) for certain loan types (particularly in the retail banking segment).

(Provisions (allowances) assessed on portfolio basis increased dramatically in course of 2007 (in 2006 they represent 2 % of total allowances and in 2007 14,5 % of total allowances)), also due to the fact that more receivables are assessed on the portfolio basis, but slightly declined in course of 2008.

……allowances for individually assessed loans are increasing since 2008

Credit registers

Banking sector – significant exposure to risk due to high information assymetry (moral hazard and adverse selection)

One of the way to reduce credit risk is to improve the information background of banks – to share information - with the help of registers of credits

Slide 26

Credit registers

Source: Financial market supervision report, 2007

Central Register of Credits (CRC) - pools information on the credit commitments of individual entrepreneurs and legal entities, in operations since 2002 (created and operated by CNB)

Banking Register of Client Information - specialises in natural persons, private citizens and sole traders, operated by the Czech Banking Credit Bureau, a.s., founded by commercial banks

SOLUS (Association for the Protection of Leasing and Loans to Consumers)

Slide 29

Credit risk assessment - Scoring

Scoring (scoring models, scoring functions)

used for the credit assessment of small companies or individuals

credit risk of individuals is assessed using more or less simple scoring function with independent variables such as income, age, number of children etc. Scoring functions are used for products like consumer credit or mortgage.

Credit risk of small companies is (usually) based on scoring function with financial ratios ad independent variables

scoring does not look at qualitative issues, as it would be inefficient (large number of credits with relatively low nominal value).

Slide 30

Credit risk assessment - Rating

Rating (more qualitative issues included)

Rating agencies – Moody´s, Standard & Poor´s, FITCH

Short-term rating (for debt instruments with a maturity less than one year)

Moody’s Standard & Poor’s

BNot Prime C

D

Investment grade

Speculative grade

Note: It is worthwhile to recall that there is a big jump between a rating of BB– and BBB+. It is a small difference in rating, but as it divides the rating scale between investment and speculative grade, it receives special attention from the investor community.

Long-term rating (maturity of more than 1 year)

Standard & Poor´s (AAA, AA, A, BBB, BB…..D), or with + - refinements

Moody´s (Aaa, Aa, ….Baa, Ba, ….)
