For a company trading below its book value, like Corning, there's an argument to be made that it should shut down and sell its assets, especially if it can sell those assets for close to book value. Why do you think Corning continued to run their business despite an ROIC less than its cost of capital? (If you recall from Module 1, ROIC is similar to the ROE we used in the beginning of this module but removes the effects of leverage)
