Deck 11: Credit Risk: Loan Portfolio and Concentration Risk

Question 1

Comparing the loan mix of an individual FI to a national benchmark loan mix is useful in determining the extent that the individual FI may differ from an efficient portfolio composition.

Answer 1

True

Question 2

Commercial bank call reports are provided by banks to the Federal Reserve and are useful in determining the proportion of loans in different classifications for the entire banking system.

Answer 2

True

Question 3

Banks whose loan portfolio composition deviates from the national benchmark should immediately implement policies to move toward benchmark alignment.

Answer 3

False

Question 4

Migration analysis is not appropriate for an FI to use in the analysis of credit risk of consumer loans and credit card portfolios.

Question 5

The expected return of a portfolio of loans is equal to the weighted average of the expected returns of the individual loans.

Question 6

Most portfolio managers will accept some level of risk above the minimum risk portfolio if they expect to receive higher returns.

Question 7

The variance of returns of a portfolio of loans normally is equal to the arithmetic average of the variance of returns of the individual loans.

Question 8

Older loan pools provide very little evidence of credit risk to a particular sector when forming new loans of loans to that sector.

Question 9

Portfolio risk can be reduced through diversification only if the returns of the loans in the portfolio are negatively correlated.

Question 10

Compared to modern portfolio theory, Moody's Analytics Portfolio Manager Model does not require loan returns to be normally distributed.

Question 11

In the past, data availability limited the use of sophisticated portfolio models to set concentration limits within lending to particular industries.

Question 12

A loan migration matrix is a measure of the probability of a loan being upgraded, downgraded, or defaulting over some period.

Question 13

The concentration limit method of managing credit risk concentration involves estimating the minimum loan amount to a single customer as a percent of capital.

Question 14

Modern portfolio theory models consider only how well diversified the entire loan portfolio is without regard to bonds that may be issued by sectors within the portfolio.

Question 15

Using migration analysis, a loan officer tracks credit rating agencies as well as their own internal models to help determine appropriate amounts to lend to certain sectors or classes.

Question 16

In the use of modern portfolio theory (MPT), the sum of the credit risks of loans under estimates the risk of the whole portfolio.

Question 17

The simple model of migration analysis tracks the credit ratings of companies that have borrowed from the FI.

Question 18

A disadvantage to modern portfolio theory (MPT) is that small institutions generally hold significant amounts of regionally specific and illiquid loans.

Question 19

Concentration limits are used to either reduce or increase exposure to specific industries.

Question 20

One advantage of portfolio diversification methods is that they are applicable to all FIs, regardless of their size.
