In financial accounting (CON 8.4[1]), a gain is when the market value of an asset exceeds the purchase price of that asset. The gain is unrealized until the asset is sold for cash, at which point it becomes a realized gain. This is an important distinction for tax purposes, as only realized gains are subject to tax. Gains are the result of circumstances, events, or transactions which affect the entity independent of revenue or owner investments. They are usually the result of holding gains, exchange transactions, events, or nonreciprocal transactions.
