1. In capital budgeting the company will use weighted average cost of capital as it includes both equity as well as debt portion and provides overall cost to the company. Also it justifies that company is atleast recovering it's actual cost of capital.
2. High fix cost will make a company leveraged as it is to be paid whether or not you are doing production or earning profits. Common stock and IPO are related to shares so no leverage involved and variable cost will vary according to output so no leverage involved.
3. Opportunity cost that investors forego because required rate of return is from the view point of investors i.e. how much return is required to keep investors with you. Other options are based on the market or cost to company.
4. Free cash flow and operating cash flow are equally preferable and that's why it can't be said that free cash flow are better representation than operating.
