For an income balance sheet excel table, I have to input net revenue/net sales and use the cost of goods sold to compute gross profit. For DAL, there's no section in the 10-K that explicitly states either, I'm assuming since they are an airline and sell services the format is a little different. Would total operating revenue and operating expenses be the correct substitute for these? For the same balance sheet I had trouble addressing this question: "What is the dollar amount of contributed capital? [preferred stock + common stock + additional paid-in capital - treasury stock]", I was having trouble solving for it since the common stock entry has no given value (I attached a screenshot of shareholder's equity for reference) and the only time preferred stock is explicitly referenced in the 10-K is in the following quote from Authorized Shares of Capital Stock: "500,000,000 shares of preferred stock, without par value". I looked up the definition of the term without par value and determined it means that these stocks are the price investors are willing to pay on the open market. However, I'm not sure how this would translate into a numerical value for the given equation. I don't need anyone to solve the equation for me, I only need help identifying the values to put into the equation for preferred stock and common stock since they aren't obvious/explicit. One final clarification point, does the amount of comparative data years include the most prior year, so in my case 2019? DELTA AIR LINES, INC.
