Final answer:
To maximize long-term share price, managers would choose to issue equity if the correct value of the shares is $6.75 and borrow if the correct value is $10.75. Investors may conclude that the share price is overvalued if IST issues equity, and the share price may decrease. If IST issues debt, investors may conclude that the share price is undervalued, and the share price may increase. If there were no distress costs, but only tax benefits, the decision would depend on the tax benefits alone.
Step-by-step explanation:
To maximize the long-term share price of the firm once its true value is known, managers would choose to issue equity if they know the correct value of the shares is $6.75, and borrow if they know the correct value of the shares is $10.75.
If IST issues equity, investors should conclude that the true value of the shares is likely lower than the current share price of $8.75, which could lead to a decrease in the share price. If IST issues debt, investors should conclude that the true value of the shares is likely higher than the current share price, which could lead to an increase in the share price.
If there were no distress costs, but only tax benefits of leverage, the decision would solely depend on the tax benefits. Managers would choose to issue debt if the tax benefits outweigh the distress costs and maximize long-term share price.
