While there are many different applications for finance, there are three basic categories: corporate finance, personal finance, and government finance. Corporate finance includes interactions, agreements, and the application of financial instruments that help companies grow, support their sales, products, and services, and invest in other companies or products. In corporate finance, the corporation itself is a financial entity, and its payment history, funds, assets, and liabilities are all part of its financial picture. Personal finance refers to the financial matters of individual people, including how they manage money, investments, and borrowing. With government finance, a local, state, or national government is the financial entity engaged in borrowing, lending, and managing funds. They can source money from other governments, banks, and private individuals by issuing bonds.
