Visit a firm’s website and obtain historical quarterly balance sheet information from it or from its SEC EDGAR fi lings http://www.walmart.com and http://www.walgreens.com may be two good sites to use). Record quarterly balance sheet data for several years in a spreadsheet. Compute and graph the firm’s financing mix (for example, by computing the ratio of current liabilities to total assets) and asset mix (by computing the ratio of current assets to total assets). What happens to the firm’s financing mix and asset mix over time? Do the financing and asset mix ratios move together? Are any seasonal effects in the firm’s working capital position and financing evident? What conclusions can you draw about the firm’s use of short-term financing?
