Your task is to determine the WACC for a given firm using what you know about WACC, as well as data you can find through research. Your deliverable is a brief report in which you state your determination of WACC, describe and justify how you determined the number, and provide relevant information as to the sources of your data. Select a publicly traded company that has debt or bonds and common stock to calculate the current WACC. One good source for financial data for companies, as well as data about their equity, is Yahoo! Finance. By looking around this site, you should be able to find the market capitalization (E) as well as the β for any publicly traded company. There are not many places left where data about corporate bonds is still available. One of them is the Finra Bonds website. To find data for a particular company’s publicly traded bonds use the Quick Search feature, then be sure to specify corporate bonds and type in the name of the issuing company. This should give you a list of all of the company’s outstanding bond issues. Clicking on the symbol for a given bond issue will lead you to the current amount outstanding and the yield to maturity. You are interested in both. The total of all bonds outstanding is D in the above formula. If you like, you can use the YTM on a bond issue that is not callable as the pre-tax cost of debt for the company.

Assumptions: As you recall, the formula for WACC is: rWACC = (E/E+D) rE + D/(E+D) rD (1-TC) The formula for the required return on a given equity investment is: ri= rf + βi * (RMkt-rf) RMkt-rf is the Market Risk Premium. For this project, you may assume the Market Risk Premium is 5% unless you can develop a better number. rf is the risk-free rate. The risk-free rate is normally the yield on US Treasury securities such as a 10-year treasury. For this assignment, please use 3.5%. You may assume a corporate tax rate of 40%.

Submit the following: Write a 350- to 700-word report that contains the following elements: Your calculated WACC How data was used to calculate WACC (provide the formula and the formula with your values substituted) Sources for your data A discussion of how much confidence you have in your answer, including what the limiting assumptions you made were, if any Include a Microsoft® Excel® file showing your WACC calculations discussed above.

The sample data is shown below, where x1 represents the mean blood pressure of the treatment group and x2 represents the mean for the control group. Use a significance level of 0.01 and the critical value method to test the claim that the drug reduces the blood pressure. We do not know the values of the population standard deviations.

Treatment Group        Control Group

n1        80 n2        70

x ?_1     186.7 x ?_2     201.9

s1         38.5 s2         39.8

1.)Write the hypotheses in symbolic form, determine if the test is right-tailed, left-tailed, or two tailed and explain why.

2.)Calculate the critical value and the test statistic.

3.)Make a decision about the null hypothesis and explain your reasoning, then make a conclusion about the claim in nontechnical terms.

1. What is balanced growth in the Solow growth model? Is it true in the real world? Give an example.

2. Use the Solow growth model to explain the following statements (assume the model with no technological change and no population growth):

1. for a given production function and depreciation rate, the saving rate determines the level of output per worker.
2. a higher saving rate will not necessarily generate more consumption per worker.
3. a higher saving rate will not produce a faster steady-state growth rate of output per worker.
