Answer:
will not be held responsible for the loss.
Explanation:
The business judgement rule is a doctrine that affects corporation's management and other agents. This doctrine is based on the idea that all business decisions yield unknown results, even the safest investments or safest projects can go wrong. Only the US government has never defaulted on a loan (US securities) but every other nation or organization has at one point in time defaulted or delayed a payment.
Investors that buy stocks from a corporation know about the risks of running a business, if they do not like to take risks, US securities are always available. As long as management (including the board) acts on good faith, within the normal scope of business, they cannot be held liable for any bad investment carried out.
If this doctrine didn't exist, no one would be able to manage a company, since no one would dare to make any decisions at all. When you calculate the price of stock or the cost of capital, you must add the risk free rate (US securities) + the risk premium.
