Woodside PetroleumThis assignment is an application of the weighted average cost of capital (WACC).You are to complete the tasks below and prepare a 1000 word report.You will be required to search for data as part of the assignment to find financial information such as the firm’s beta and the current risk free rate. This has been provided in the attached Spreadsheet.Tasks:1. Calculate the Weighted Average Cost of Capital using an appropriate technique.2. Explain your calculations and the judgements you made in arriving at your answer.3. Calculate gearing ratios and describe any difficulties in doing so.4. Analyse your findings with reference to capital structure theory.5. Provide a recommendation to the Board on the firm’s current capital structure.6. Provide a reflection on the report as follows:• What weights should we use when calculating the WACC, market value weights or accounting book values? To do this find the market value of equity (no. of shares times the share price) and the market value of financial debt (if no traded debt you may need to use accounting book values) then compare the weight calculations with those calculated using book values (shareholder funds plus total financial debt). Do they differ and what would you use/• What risk free rate would you use – 30 day, 3 month, 6 month 1 year, 3 year, 10 year, of 30 year? Would it make a difference?• Should you use a published beta such as that available on the Morning Star Data Base, calculate the beta yourself (you can get share prices and market indexes from Yahoo Finance), or pay someone to do it for you?• Do you calculate a return on the market or use the spread between the market and the risk free rate (6% to 8% premium according to research).• Do you use the debt expense as per the accounts or some indicator rate?
