1.    Consider the following balance sheet for WatchoverU Savings, Inc. (in millions):
    Assets        Liabilities and Equity
    Floating-rate mortgages        1-year time deposits
        (currently 10% annually)    $50        (currently 6% annually)    $70
    30-year fixed-rate loans        3-year time deposits
        (currently 7% annually)    $50        (currently 7% annually)    $20
                Equity    $10
        Total Assets    $100        Total Liabilities & Equity    $100
    a.    What is WatchoverU’s expected net interest income at year-end?
    Current expected interest income:  $50m(0.10) + $50m(0.07) = $8.5m. 
Expected interest expense:        $70m(0.06)  $20m(0.07) = $5.6m. 
Expected net interest income:                          $8.5m  $5.6m = $2.9m.
    b.    What will net interest income be at year-end if interest rates rise by 2 percent?
      After the 200 basis point interest rate increase, net interest income declines to:
    50(0.12) + 50(0.07)  70(0.08)  20(.07) = $9.5m  $7.0m = $2.5m, a decline of $0.4m.
    c.    Using the cumulative repricing gap model, what is the expected net interest income for a 2 percent increase in interest rates?
      Wachovia’s' repricing or funding gap is $50m  $70m = $20m. The change in net interest income using the funding gap model is ($20m)(0.02) = $.4m.
d.What will net interest income be at year-end if interest rates on RSAs increase by 2 percent but interest rates on RSLs increase by 1 percent? Is it reasonable for changes in interest rates on RSAs and RSLs to differ? Why?
    After the unequal rate increases, net interest income will be 50(0.12) + 50(0.07)  70(0.07)
  20(.07) = $9.5m  $6.3m = $3.2m, an increase of $0.3m. It is not uncommon for interest rates to adjust in an unequal manner on RSAs versus RSLs. Interest rates often do not adjust solely because of market pressures. In many cases the changes are affected by decisions of management. Thus, you can see the difference between this answer and the answer for part a.
2.    Use the following information about a hypothetical government security dealer named M.P. Jorgan. Market yields are in parenthesis, and amounts are in millions.
    Assets        Liabilities and Equity
    Cash    $10    Overnight repos    $170
    1-month T-bills (7.05%)    75    Subordinated debt
    3-month T-bills (7.25%)    75    7-year fixed rate (8.55%)    150
    2-year T-notes (7.50%)    50
    8-year T-notes (8.96%)    100
    5-year munis (floating rate)
        (8.20% reset every 6 months)      25    Equity      15
    Total assets    $335    Total liabilities & equity    $335
    a.    What is the repricing gap if the planning period is 30 days? 3 months? 2 years? Recall that cash is a noninterest-earning asset.
    Repricing gap using a 30-day planning period = $75  $170 = $95 million.
Repricing gap using a 3-month planning period = ($75 + $75)  $170 = -$20 million.
    Reprising gap using a 2-year planning period = ($75 + $75 + $50 + $25)  $170 =  +$55 million.
    b.    What is the impact over the next 30 days on net interest income if interest rates increase 50 basis points?  Decrease 75 basis points?
    If interest rates increase 50 basis points, net interest income will decrease by $475,000.
    NII = CGAP(R) = $95m.(.005) = -$0.475m.
   
If interest rates decrease by 75 basis points, net interest income will increase by $712,500. NII = CGAP(R) = $95m.(-.0075) = $0.7125m.
c.The following one-year runoffs are expected:  $10 million for two-year T-notes and $20 million for eight-year T-notes. What is the one-year repricing gap?
    The repricing gap over the 1-year planning period = ($75m. + $75m. + $10m. + $20m. + $25m.)  $170m. = +$35 million.
    d.    If runoffs are considered, what is the effect on net interest income at year-end if interest rates rise 50 basis points?  Decrease 75 basis points?
    If interest rates increase 50 basis points, net interest income will increase by $175,000. 
NII = CGAP(R) = $35m.(0.005) = $0.175m.
    If interest rates decrease 75 basis points, net interest income will decrease by $262,500. NII = CGAP(R) = $35m.(-0.0075) = -$0.2625m.
3.    A bank has the following balance sheet:
Assets                Avg. Rate    Liabilities/Equity            Avg. Rate
Rate sensitive      $550,000      7.75%    Rate sensitive      $375,000        6.25%   
Fixed rate        755,000      8.75        Fixed rate          805,000        7.50
Nonearning    unequal    265,000            Non paying        390,000
  Total        $1,570,000              Total        $1,570,000
Suppose interest rates rise such that the average yield on rate sensitive assets increases by 45 basis points and the average yield on rate sensitive liabilities increases by 35 basis points.
a.    Calculate the bank’s repricing GAP and gap ratio.
