Accounting

• 1. Introduction

  ›

  Accounting is the practice of recording and processing information about economic activity, and it is older than writing itself. In ancient Mesopotamia, before alphabets existed, people were already keeping tallies of grain and livestock. The clay tablets they left behind are among the earliest evidence that humans felt a pressing need to track what they owned, what they owed, and what they had traded away. That impulse never left us. It only grew more sophisticated. How did a simple tally system become the backbone of modern commerce? Who turned it into a profession, a science, and occasionally a scandal? And why does a 15th-century Italian friar still get credit for shaping the way nearly every business on earth keeps its books today?

• 2. Ancient Roots

  ›

  By the time of Emperor Augustus, the Roman government had access to detailed financial information about its own operations. That fact alone tells us something remarkable: the ancient world was not improvising its record-keeping. Evidence of early bookkeeping has been found in ancient Iran, and auditing systems were already in use among the Egyptians and Babylonians long before Rome rose to power. In Mesopotamia, accounting developed alongside writing and money as three closely linked technologies. Each one made the others more powerful. A merchant who could write could record a debt. A merchant who could record a debt could extend credit. The invention of formal numerals accelerated all of this. When Arabic numerals spread across the Mediterranean world and displaced the cumbersome Roman numeral system, accounting procedures became significantly more efficient. Mediterranean merchants refined these methods further, and from that community of traders grew the accounting traditions of medieval Europe.

• 3. Pacioli and the Double Entry

  ›

  Luca Pacioli was an Italian mathematician and a Franciscan friar, and in 1494 he published a book called the Summa de arithmetica. It was the first published work to describe the double-entry bookkeeping system in detail, and it earned him the informal title of "Father of Accounting." Double-entry bookkeeping had not been invented in Venice, but it had been developed and refined there, and Pacioli's publication gave it a fixed, teachable form. The core principle is simple but powerful: every financial transaction is recorded in two places, as both a debit and a credit, so that the books must always balance. A mistake, a fraud, or an omission will eventually cause the accounts to fall out of balance, which makes the system a built-in error detector. From Pacioli's publication onward, this approach became the standard framework that professionals and businesses would use to manage their records.

• 4. A Profession Takes Shape

  ›

  Accounting began its transformation into a recognized profession during the 19th century. Local professional bodies in England gradually merged until they formed the Institute of Chartered Accountants in England and Wales in 1880. That organization, known today as ICAEW, represents one of the earliest formal structures to govern what accountants could call themselves, how they trained, and what ethical standards they were expected to meet. Accounting firms grew across the United States and Europe in the late 19th and early 20th centuries. Through a series of mergers across the middle and late 20th century, five firms came to dominate the global auditing market: Arthur Andersen, Deloitte, Ernst and Young, KPMG, and PricewaterhouseCoopers. That group was known as the Big Five. Then, in December 2001, Enron filed for Chapter 11 bankruptcy protection, and the Big Five became four.

• 5. The Enron Reckoning

  ›

  The year 2001 brought a wave of financial fraud cases involving some of the most prominent names in American business: Enron, WorldCom, Qwest, and Sunbeam, among others. Enron's collapse was the most consequential. The scandal was not just the largest bankruptcy reorganization in American history at the time; it also triggered the dissolution of Arthur Andersen, then one of the five largest accounting firms in the world. Irregular accounting procedures had been conducted throughout the 1990s before the collapse finally came. Management had manipulated figures in financial reports to make the company's performance look stronger than it was. In some cases across the broader wave of scandals, tax and regulatory incentives had encouraged companies to take on extraordinary and unjustified risk. The political response was the Sarbanes-Oxley Act, passed in the United States in 2002. The law significantly raised criminal penalties for securities fraud and for destroying or fabricating records in federal investigations.

• 6. Fields Within the Field

  ›

  Financial accounting produces reports for people outside an organization: investors, regulators, and creditors. Those reports are historical by design. Financial statements are often published six to ten months after the end of the accounting period they describe. Management accounting works differently. It produces both backward-looking reports and forward-looking ones, including budgets, and it serves people inside the organization rather than outside it. In 2014, the Chartered Institute of Management Accountants created the Global Management Accounting Principles after drawing on research from across 20 countries on five continents. Tax accounting in the United States operates under a distinct set of rules that can differ substantially from the generally accepted accounting principles used in financial reporting. Forensic accounting occupies a more specialized corner of the profession: it handles engagements that arise from actual or anticipated disputes or litigation. The word forensic, in this context, refers to what is suitable for use in a court of law. Political campaign accounting, a branch that was first formally introduced in the March 1976 issue of The Journal of Accountancy, deals with financial systems that must comply with laws governing campaign operations.

• 7. Standards and Governance

  ›

  Generally accepted accounting principles, known as GAAP, are not a single universal document. They are standards issued by national regulatory bodies, and they vary by country. In the United States, the Financial Accounting Standards Board issues these standards. In the United Kingdom, the Financial Reporting Council performs the same role. On the international level, the International Accounting Standards Board issues the International Financial Reporting Standards, which have been implemented by 147 countries. As of 2012, all major economies had plans to converge toward or adopt those international standards. The largest global accountancy body by membership is the Association of Chartered Certified Accountants, known as ACCA, with over 320,000 members. Students pursuing ACCA qualification must pass a total of 14 exams arranged across three levels. The International Federation of Accountants supports independent boards that set standards for auditing, ethics, education, and public sector accounting on a global basis.

• 8. Research and Integrity

  ›

  Accounting research draws on methods from across the social sciences: archival studies, experiments, formal mathematical modeling, interpretive work that focuses on language and meaning, and critical approaches that examine how power shapes accounting practice. One documented pattern in the academic literature is that leading accounting journals publish fewer research articles in total than comparable journals in economics and other business disciplines. A study based on academic author rankings concluded from this that the competitive value of a single publication in a top accounting journal is higher in accounting than in any other business field, including marketing. On the question of integrity, the distinction the profession draws between fraud and error is precise: fraud is an intentional misstatement or omission involving deception, a criminal act. An error is unintentional. Primary responsibility for preventing and detecting both rests with an organization's own management, a principle that the Sarbanes-Oxley Act reinforced by making the consequences of deliberate deception far more severe.
