¶ … working average cost of capital (WACC) is an important component of determining what operations to finance and comparing different alternatives. This calculation takes into account the costs that go into providing the capital that a firm can use for different ends. It is sometimes referred to as the "hurdle" rate because projects must always return a require amount to make the investment viable; with a few exceptions.

For example, assets that were financed through a bank will have a different repayment structure and rate than assets that were financed through the sale of stock. The company must first average the cost of all the different financing activities that it has engaged in before it can calculate a baseline for the WACC. Other factors are also important and play a role in the WACC calculations such as the "risk-free rate." This is the rate that is considered to be virtually risk free and government bonds are typically used. If the company can invest in a risk-free investment, then there is an opportunity cost in investing in alternative investments and this must be considered. There is also an inflation...

Furthermore, the company must also include risk in the calculation. There is always a risk that the investment will not provide the returns expected and the company must also include risk when calculating WACC.
Airgo in Korea

It has already been determined that the company will have a twelve percent working cost of capital for the investment before risk has been considered. Adding risk to this equation will be a considered along many different lines. There will be some level of risk involved with operating in a foreign country. South Korea has a different culture and a different environment altogether and some level of risk must be considered in operating in this country.
