Final answer:
The best estimate for the intrinsic stock price per share is $20.
Step-by-step explanation:
To estimate the intrinsic stock price per share, we need to calculate the present value of the company's operations and subtract the unrelated short-term investments. First, we add up the long-term debt, preferred stock, and total common equity to get the total capital of the company: $90 million + $30 million + $100 million = $220 million. Then, we subtract the short-term investments unrelated to operations: $220 million - $20 million = $200 million. Finally, we divide the value of the company's operations by the number of shares to get the intrinsic stock price per share: $200 million / 10 million = $20 per share.
