(3) Based on the information above, cheaper debt financing is exhausted when the value
of projects accepted exceeds $1,500,000. Retained earnings can finance $2,500,000 of new
projects without having to issue additional debt. In the prior calculation of weighted average costs
of capital, a weighted average costs of capital for cheap debt and external equity financing was
not needed because Star Products runs out of financing from cheap debt first.

Group exercises are available on www.myfinancelab.com.
Accurately measuring the cost of capital is the topic of this chapter. The group exercise will use current
information from the shadow firm to provide details for each group’s fictitious firm. The balance sheet is the
source of this information and the assignment begins with an investigation into the shadow firm’s debt/equity mix.
