Debt is that which is owed; usually referencing assets owed, but the term can also cover moral obligations and other interactions not requiring money. In the case of assets, debt is a means of using future purchasing power in the present before a summation has been earned. Some companies and corporations use debt as a part of their overall corporate finance strategy. A debt is created when a creditor agrees to lend a sum of assets to a debtor. In modern society, debt is usually granted with expected repayment; in most cases, plus interest.
