1. What are the two different general interpretations of the concept of duration, and

what is the technical definition of this term? How does duration diFinffer from

maturity?

2. What is dollar duration? How is dollar duration different from duration?

3. Financial Institution XY has assets of $1 million invested in a 30-year, 10 per cent

semi-annual coupon Treasury Bond selling at par. The duration of this bond has

been estimated at 9.94 years. The assets are financed with equity and a $900 000,

two-year, 7.25 per cent semi-annual coupon capital note selling at par.

(a) What is the leverage adjusted duration gap of Financial Institution XY?

(b) What is the impact on equity value if the relative change in all market interest

rates is a decrease of 20 basis points? Note: The relative change in interest rates

is R/(1+R/2) = -0.0020.

(c) Using the information calculated in parts (a) and (b), what can be said about the

desired duration gap for a financial institution if interest rates are expected to

increase or decrease.

(d) Verify your answer to part (c) by calculating the change in the market value of

equity assuming that the relative change in all market interest rates is an

increase of 30 basis points.

(e) What would the duration of the assets need to be to immunise the equity from

changes in market interest rates?

4. The duration of an 11-year, $1000 Treasury Bond paying a 10 per cent semiannual coupon and selling at par has been estimated at 6.763 years.

(a) What is the modified duration of the bond? What is the dollar duration of the

bond?

(b) What will be the estimated price change on the bond if interest rates increase

0.10 per cent (10 basis points)? If rates decrease 0.20 per cent (20 basis points)?

(c) What would the actual price of the bond be under each rate change situation in

part (b) using the traditional present value bond pricing techniques? What is the

amount of error in each case?

5. The following balance sheet information is available (amounts in thousands of dollars

and duration in years) for a financial institution:

T-notes $90 0.50

T-notes $55 0.90

year)

$176 x

Loans $2724 7.00

Deposits $2092 1.00

Interbank

Treasury Bonds are five-year maturities paying 6 per cent semi-annually and selling at

par.

(a) What is the duration of the T-Bond portfolio?

(b) What is the average duration of all the assets?

(c) What is the average duration of all the liabilities?

(d) What is the leverage adjusted duration gap (DGAP)? What is the interest rate risk

exposure?

(e) What is the forecasted impact on the market value of equity caused by a relative

upward shift in the entire yield curve of 0.5 per cent [that is, R/(1+R) = 0.0050]?

(f) If the yield curve shifts downward by 0.25 per cent [that is, R/(1+R) = -0.0025],

what is the forecasted impact on the market value of equity?

(g) What variables are available to the financial institution to immunise the balance

sheet? How much would each variable need to change to get DGAP equal to 0?
