Copper Banks asset and liability management team is assessing the banks portfolio of assets and liabilities. They report the following distribution of maturities and repricing opportunities:

	Coming Week	Next 30 Days	Next 31-90 Days	More Than 90 Days
Interest-sensitive assets
Loans	$300.00	$500.00	$355.00	$475.00
Securities	35.00	49.00	25.00	54.00
Interest-sensitive liabilities
Transaction deposits	$415.00	$ 400.00	$ 27.00	$ 35.00
Time accts.	175.00	250.00	235.00	90.00
Money market borrowings	245.00	140.00	150.00	35.00

1. Calculate the interest sensitive GAP for the four periods and the cumulative GAP to show when and by how much the bank is exposed to interest rate risk.

2. For each repricing interval, what changes in interest rates will be beneficial and which will be damaging, given the current portfolio position? Assess the non-cumulative and cumulative GAP.
