One important function performed by CPAs relates to assurance services. The most commonly performed assurance services are financial audit services where CPAs attest to the reasonableness of disclosures, the freedom from material misstatement, and the adherence to the applicable generally accepted accounting principles (GAAP) in financial statements. CPAs can also be employed within corporations (termed "the private sector" or "industry") in finance or operations positions such as financial analyst, finance manager, controller, chief financial officer (CFO), or chief executive officer (CEO). These CPAs do not provide services directly to the public.
