5. Whereas commercial banks take deposits from some customers and make loans to other customers, the
principal activities of investment banks are (1) to help firms issue new stock and bonds and (2) to give
firms advice with regard to mergers and other financial matters. However, financial corporations often
own and operate subsidiaries that operate as commercial banks and others that are investment banks.
This was not true some years ago, when the two types of banks were required by law to be completely
independent of one another.
6. The term “equity carve-out” refers to the situation where a firm’s managers give themselves the right to
purchase new stock at a price far below the going market price. Since this dilutes the value of the
public stockholders, it “carves out” some of their value.
7. Suppose a company issued 30-year bonds 4 years ago, when the yield curve was inverted. Since then
long-term rates (10 years or longer) have remained constant, but the yield curve has resumed its
normal upward slope. Under such conditions, a bond refunding would almost certainly be profitable.
8. The appropriate discount rate to use when analyzing a refunding decision is the after-tax cost of new
debt, in part because there is relatively little risk of not realizing the interest savings.
9. If the firm uses the after-tax cost of new debt as the discount rate when analyzing a refunding decision,
and if the NPV of refunding is positive, then the value of the firm will be maximized if it immediately
calls the outstanding debt and replaces it with an issue that has a lower coupon rate.
