You have been hired as a risk manager for Acorn Savings and Loan. Currently, Acorn's balance sheet is as follows (in millions of dollars):

When you analyze the duration of loans, you find that the duration of the auto loans is 1.8 years, while the mortgages have a duration of 6.9

years. Both the cash reserves and the checking and savings accounts have a zero duration. The CDs have a duration of 1.9 years, and the long-term financing has a 9.9-year duration.

a. What is the duration of Acorn's equity?

The duration of the assets is ? years. (Round to two decimal places.)

The duration of the liabilities is ? years. (Round to two decimal places.)

The duration of the equity is ? years. (Round to two decimal places.)

b. Suppose Acorn experiences a rash of mortgage prepayments, reducing the size of the mortgage portfolio from $ 148.1 million to $ 98.7 million, and increasing cash reserves to $ 99.8 million. What is the duration of Acorn's equity now?

The duration of the assets is ? years. (Round to two decimal places.)

The duration of the equity is ? years. (Round to two decimal places.)

If interest rates are currently 4 % and were to fall to 3 % estimate the approximate change in the value of Acorn's equity. (Assume interest rates are APRs based on monthly compounding.)

We would expect the value of Acorn's equity to rise or drop ? by approximately ?% (Round to two decimal places.)
