What is the main difference between debt and other liabilities, like accounts payable?

(a) Debt has an explicit charge, an interest rate

(b) Debt represents ownership in the company

(c) Debt is only owed to suppliers

(d) All the above

Service companies, since they provide services rather than goods, dont hold inventories (or dont hold inventories that are meaningful for their sales process and therefore measures of inventories, like inventory turnover, are meaningless). Instead, what is the critical asset usage metric for service companies?

(a) Spread, or the earnings on receivables compared to the cost of payables

(b) Collection time, or the ability to convert receivables quickly to cash

(c) Capital intensity, like PP&E, which reflects substantial equipment assets

(d) Intangibles and goodwill, reflecting successful acquisitions

(e) There is no consistent asset usage metric indicating a successful service-based business model
