This assignment is intended as an extra credit assignment for students who would like an opportunity to improve their overall class performance. This assignment seeks to promote the understanding of the key financial concepts that have been covered in this class so far and help students develop apply them in real- life work context. In this assignment, you will be assigned to analyze the annual 10-K statements from 1) Apple, 2) ExxonMobil, and 3) WalMart. Pdf copies of these statements will be provided in Canvas. The ratios you will be required to compute for the last three years for each of these companies will be as follows: Return on Assets (ROA), Return on Equity (ROE), profit margin (Net Income / Sales), Average Tax Rate, the book-to-market ratio (that is, the book value of the firms equity divided by the market value of the firms equity), Earnings per share, the firms P/E ratio, and Dividend per share, and stock price based on the dividend discount model. The formula to be used for each of the above items will be as follows: ROA = Net Income / Total Assets, ROE = Net Income / Total Equity, Profit Margin = Net Income / Sales, Average Tax Rate = Tax Expenses / Taxable Income (taxable income can be displayed as income before taxes in some cases), Book-to-market ratio = Book value of equity / Market value of equity, where Market value of equity = stock price of each individual share X Number of shares outstanding. Earnings per share = Net Income / Number of shares outstanding, P/E Ratio (Price/Earnings ratio) = Current market price of shares / Earnings per share. Dividend per share = Total Dividend shares / Number of shares outstanding.
