Calculating the total capital of a company?
I was wondering how do we calculate the total capital of a company? Which items should I look for in the financial statements? Total capital usually refers to the sum of long-term debt and total shareholder equity; both of these items can be found on the company's balance sheet. This is one of the calculations that's traditionally used when determining a company's return on capital.  I'll use the balance sheet from Gilead Sciences' (GILD) 2012 10-K form as an example. Net long-term debt was $7,054,555,000 and total stockholder equity was $9,550,869,000 which should give a grand total of $16,605,424,000 for total capital. (I know you can do the math, but I always find an example helpful if it uses realistic numbers).  You may sometimes hear the term "total capital" referring to "total capital stock" or "total capital assets," in which case it may be referring to physical capital, i.e. assets like inventory, PP&E, etc., instead of financial capital/leverage. And how do I calculate notes payable? Is the same as accounts payable? As the word "payable" suggests, both are liabilities. However, I've always been taught that accounts payable are debts a business owes to its suppliers, while notes payable are debts a business owes to banks and other institutions with which it has signed a formal agreement and which use formal debt instruments, e.g. a loan contract. This definition seems to match various articles I found online.  On a balance sheet, you can usually determine notes payable by combining the short-term debt of the company with the current portion of the long-term debt. These pieces comprise the debt that is due within the fiscal year. In the balance sheet for Gilead Sciences, I would only include the $1,169,490,000 categorized as "Current portion of long-term debt and other obligations, net" term, since the other current liabilities don't look like they would involve formal debt contracts.  Since the notes payable section of GILD's balance sheet doesn't seem that diverse and therefore might not make the best example, I'll include the most recent balance sheet Monsanto as well.1 Monsanto's balance sheet lists a term called "Short-term debt, including current portion of long-term debt" with a value of $36 million. This looks like almost the exact definition of notes payable. 1. Note that this financial statement is called a Statement of Consolidated Financial Position on Monsanto's 10-K.
