Which is a surprise for a top contributer. They usually take their time, and focus on quality rather than quantity.

Accountancy (profession) or accounting (methodology) is the measurement, disclosure or provision of assurance about financial information primarily used by managers, investors, tax authorities and other decision makers to make resource allocation decisions within companies, organizations, and public agencies. The terms derive from the use of financial accounts. Accounting is also widely referred to as the "language of business".
Financial accounting is one branch of accounting and historically has involved processes by which financial information about a business is recorded, classified, summarized, interpreted, and communicated; for public companies, this information is generally publicly-accessible. By contrast management accounting information is used within an organization and is usually confidential and accessible only to a small group, mostly decision-makers. Tax Accounting is the accounting needed to comply with jurisdictional tax regulations.
Practitioners of accountancy are known as accountants. There are many professional bodies for accountants throughout the world. Many allow their members to use titles indicating their membership or qualification level. Examples are Chartered Certified Accountant (ACCA or FCCA), Chartered Accountant (FCA, CA or ACA), Management Accountant (ACMA, FCMA or AICWA), Certified Public Accountant (CPA) and Certified General Accountant (CGA).
Auditing is a related but separate discipline, with two sub-disciplines: internal auditing and external auditing. External auditing is the process whereby an independent auditor examines an organization's financial statements and accounting records in order to express an opinion as to the truth and fairness of the statements and the accountant's adherence to Generally Accepted Accounting Principles (GAAP), or International Financial Reporting Standards (IFRS), in all material respects. Internal auditing aims at providing information for management usage, and is typically carried out by auditors employed by the company, and sometimes by external service providers.
Accounting/accountancy attempts to create accurate financial reports that are useful to managers, regulators, and other stakeholders such as shareholders, creditors, or owners. The day-to-day record-keeping involved in this process is known as bookkeeping.
Accounting is the measurement of financial transactions which are transfers of legal property rights made under contractual relationships. Non-financial transactions are specifically excluded due to conservatism and materiality principles.
At the heart of modern financial accounting is the double-entry bookkeeping system. This system involves making at least two entries for every transaction: a debit in one account, and a corresponding credit in another account. The sum of all debits should always equal the sum of all credits, providing a simple way to check for errors. This system was first used in medieval Europe, although claims have been made that the system dates back to Ancient Rome or Greece.
According to critics of standard accounting practices, it has changed little since. Accounting reform measures of some kind have been taken in each generation to attempt to keep bookkeeping relevant to capital assets or production capacity. However, these have not changed the basic principles, which are supposed to be independent of economics as such. In recent times, the divergence of accounting from economic principles has resulted in controversial reforms to make financial reports more indicative of economic reality.
Accountancy's infancy dates back to the earliest days of human agriculture and civilization (the Sumerians in Mesopotamia), when the need to maintain accurate records of the quantities and relative values of agricultural products first arose. Simple accounting is mentioned in the Christian Bible (New Testament) in the Book of Matthew, in the Parable of the Talents (Matt. 25:19). The Islamic Quran also mentions simple accounting for trade and credit arrangements (Quran 2: 282).
Twelfth-century CE Arab writer Ibn Taymiyyah mentioned in his book Hisba (literally, "verification" or "calculation") detailed accounting systems used by Muslims as early as in the mid-seventh century CE. These accounting practices were influenced by the Roman and the Persian civilizations that Muslims interacted with. The most detailed example Ibn Taymiyyah provides of a complex governmental accounting system is the Divan of Umar, the second Caliph of Islam, in which all revenues and disbursements were recorded. The Divan of Umar has been described in detail by various Islamic historians and was used by Muslim rulers in the Middle East with modifications and enhancements until the fall of the Ottoman Empire.
Luca Pacioli and the birth of modern accountancy
The first book on accounting was written by a Croatian merchant Benedetto Cotrugli, who is also known as Benedikt Kotruljević, from the city of Dubrovnik. During his life in Italy he met many merchants and decided to write Della Mercatura et del Mercante Perfetto (On Trade and the Perfect Merchant) in which he elaborated on the principles of the modern double-entry book-keeping. He finished his lifework in 1458. However, his work was not published until 1573, as a result of which his contributions to the field have been overlooked by the general public.[citation needed]
For this reason, Luca Pacioli (1445 - 1517), also known as Friar Luca dal Borgo, is credited for the "birth" of accounting. His Summa de arithmetica, geometrica, proportioni et proportionalita (Summa on arithmetic, geometry, proportions and proportionality, Venice 1494), a synthesis of the mathematical knowledge of his time, includes the first published description of the method of keeping accounts that Venetian merchants used at that time, known as the double-entry accounting system. Although Pacioli codified rather than invented this system, he is widely regarded as the "Father of Accounting". The system he published included most of the accounting cycle as we know it today. He described the use of journals and ledgers, and warned that a person should not go to sleep at night until the debits equaled the credits! His ledger had accounts for assets (including receivables and inventories), liabilities, capital, income, and expenses — the account categories that are reported on an organization's balance sheet and income statement, respectively. He demonstrated year-end closing entries and proposed that a trial balance be used to prove a balanced ledger. His treatise also touches on a wide range of related topics from accounting ethics to cost accounting.
