Deck 11: Credit Risk: Loan Portfolio and Concentration Risk

Question 1

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

Answer 1

False

Question 2

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

Answer 2

True

Question 3

Loan loss ratio models are based on historical loan loss ratios of specific sectors relative to the historic loan loss ratios of the FI's entire loan portfolio.

Answer 3

True

Question 4

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 5

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

Question 6

General diversification limits established by life and property and casualty insurance regulators are based on the concepts of modern portfolio theory.

Question 7

Included in the Moody's Analytics model are recovery rates on defaulted loans.

Question 8

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

Question 9

The all-in-spread (AIS) used in the Moody's Analytics model is the difference between the interest rate on a loan and the prime lending rate at the time the loan was originated.

Question 10

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

Question 11

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

Question 12

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

Question 13

OSFI policy for measuring credit concentration risk favours technical models over subjective analysis.

Question 14

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

Question 15

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

Question 16

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.

Question 17

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 18

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

Question 19

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

Question 20

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