The cost principle states that assets must be recorded on the date they are acquired, and at the amount for which they were acquired (regardless of whether they change in value over time). For example, the hospital records the value of the purchased medical equipment at the precise value it paid for them on May 1, despite the fact that such equipment depreciates over time.
Managerial accounting (also called management accounting) identifies financial information that helps managers run a company’s operations efficiently. Managerial accountants may analyze specific products, costs, or projects, and then provide this information to a company’s managers to enable them to make more informed judgements. Reports that managerial accountants provide to managers include cost analysis, constraint analysis, capital budgeting, trend forecasting, inventory analysis, and other types of product or project analysis, according to the industry in which the company operates. Managerial accounting is largely an internal system.
Tax gain-loss harvesting is another form of tax planning or management relating to investments. It is helpful because it can use a portfolio's losses to offset overall capital gains. According to the IRS, short and long-term capital losses must first be used to offset capital gains of the same type. In other words, long-term losses offset long-term gains before offsetting short-term gains. As of 2018, short-term capital gains, or earnings from assets owned for less than one year, are taxed at ordinary income rates. 
At least a bachelor's degree in accounting or a related field is required for most accountant and auditor job positions, and some employers prefer applicants with a master's degree.[54] A degree in accounting may also be required for, or may be used to fulfill the requirements for, membership to professional accounting bodies. For example, the education during an accounting degree can be used to fulfill the American Institute of CPA's (AICPA) 150 semester hour requirement,[55] and associate membership with the Certified Public Accountants Association of the UK is available after gaining a degree in finance or accounting.[56]
In most cases, accountants use generally accepted accounting principles (GAAP) when preparing financial statements in the U.S. GAAP is a set of standards and principles designed to improve the comparability and consistency of financial reporting across industries. Its standards are based on double-entry accounting, a method in which every accounting transaction is entered as both a debit and credit in two separate general ledger accounts that will roll up into the balance sheet and income statement.
Managerial accounting uses much of the same data as financial accounting, but it organizes and utilizes information in different ways. Namely, in managerial accounting, an accountant generates monthly or quarterly reports that a business's management team can use to make decisions about how the business operates. Managerial accounting also encompasses many other facets of accounting, including budgeting, forecasting and various financial analysis tools. Essentially, any information that may be useful to management falls underneath this umbrella.
