Stock (400 shares), reduced rate on dividends:
Industrial bonds (eight bonds):
The bonds generate $92.50 in interest income, which is taxable at 38%. The bonds decreased in value
by $6.25. The total before tax return is therefore (92.50-6.25)/970 = 8.89%. The tax treatment of the

positive. The use of Jensen’s measure is less than ideal because the Stalcheck’s portfolio cuts across

This case allows students to use a simplified portfolio to evaluate the four formula plans presented in the
text. For ease in computation and discussion, we have assumed that fractional shares can be purchased.
Instructors may wish to revise the numbers to eliminate fractional shares.
