Finance
Financial accounting refers to the processes used to generate interim and annual financial statements. The results of all financial transactions that occur during an accounting period are summarized in the balance sheet, income statement, and cash flow statement. The financial statements of most companies are audited annually by an external CPA firm.

For some, such as publicly traded companies, audits are a legal requirement. However, lenders also typically require the results of an external audit annually as part of their debt covenants. Therefore, most companies will have annual audits for one reason or another.
