Gains and Losses

It would probably be ideal if business and life were as simple as producing goods, selling them and recording the profits. But there are often circumstances that disrupt the cycle, and it's part of the accountants job to report these as well. Changes in the business climate, or cost of goods or any number of things can lead to exceptional or extraordinary gains and losses in a business. Some things that can alter the income statement can include downsizing or restructuring the business. This used to be a rare thing in the business environment, but is now fairly commonplace. Usually it's done to offset losses in other areas and to decrease the cost of employees' salaries and benefits. However, there are costs involved with this as well, such as severance pay, outplacement services, and retirement costs.

In other circumstances, a business might decide to discontinue certain product lines. Western Union, for example, recently delivered its very last telegram. The nature of communication has changed so drastically, with email, cell phones and other forms, that telegrams have been rendered obsolete. When you no longer sell enough of a product at a high enough profit to make the costs of manufacturing it worthwhile, then it's time to change your product mix.

Lawsuits and other legal actions can cause extraordinary losses or gains as well. If you win damages in a lawsuit against others, then you've incurred an extraordinary gain. Likewise if your own legal fees and damages or fines are excessive, then these can significantly impact the income statement.

Occasionally a business will change accounting methods or need to correct any errors that had been made in previous financial reports. Generally Accepted Accounting Procedures (GAAP) require that businesses make any one-time losses or gains very visible in their income statement.

Accounting Principles

If everyone involved in the process of accounting followed their own system, or no system at all, there's be no way to truly tell whether a company was profitable or not. Most companies follow what are called generally accepted accounting principles, or GAAP, and there are huge tomes in libraries and bookstores devoted to just this one topic. Unless a company states otherwise, anyone reading a financial statement can make the assumption that company has used GAAP.
 

If GAAP are not the principles used for preparing financial statements, then a business needs to make clear which other form of accounting they're used and are bound to avoid using titles in its financial statements that could mislead the person examining it.
 

GAAP are the gold standard for preparing financial statement. Not disclosing that it has used principles other than GAAP makes a company legally liable for any misleading or misunderstood data. These principles have been fine-tuned over decades and have effectively governed accounting methods and the financial reporting systems of businesses. Different principles have been established for different types of business entities, such for-profit and not-for-profit companies, governments and other enterprises.
 

GAAP are not cut and dried, however. They're guidelines and as such are often open to interpretation. Estimates have to be made at times, and they require good faith efforts towards accuracy. You've surely heard the phrase "creative accounting" and this is when a company pushes the envelope a little (or a lot) to make their business look more profitable than it might actually be. This is also called massaging the numbers. This can get out of control and quickly turn into accounting fraud, which is also called cooking the books. The results of these practices can be devastating and ruin hundreds and thousands of lives, as in the cases of Enron, Rite Aid and others.
