Depreciation in the context of "IAS 16"

In business and accounting, net income (also total comprehensive income, net earnings, net profit, bottom line, sales profit, or credit sales) is an entity's income minus cost of goods sold, expenses, depreciation and amortization, interest, and taxes, and other expenses for an accounting period.

It is computed as the residual of all revenues and gains less all expenses and losses for the period, and has also been defined as the net increase in shareholders' equity that results from a company's operations. It is different from gross income, which only deducts the cost of goods sold from revenue.

Economics, business, accounting, and related fields often distinguish between quantities that are stocks and those that are flows. These differ in their units of measurement. A stock is measured at one specific time, and represents a quantity existing at that point in time (say, December 31, 2004), which may have accumulated in the past. A flow variable is measured over an interval of time. Therefore, a flow would be measured per unit of time (say a year). Flow is roughly analogous to rate or speed in this sense.

For example, U.S. nominal gross domestic product refers to a total number of dollars spent over a time period, such as a year. Therefore, it is a flow variable, and has units of dollars/year. In contrast, the U.S. nominal capital stock is the total value, in dollars, of equipment, buildings, and other real productive assets in the U.S. economy, and has units of dollars. The diagram provides an intuitive illustration of how the stock of capital currently available is increased by the flow of new investment and depleted by the flow of depreciation.

Foreign exchange reserves, also called Forex reserves, in a strict sense, are foreign-currency deposits held by nationals and monetary authorities. However, in popular usage and in the list below, it also includes gold reserves, special drawing rights (SDRs) and IMF reserve position because this total figure, which is usually more accurately termed as official reserves or international reserves or official international reserves, is more readily available and also arguably more meaningful. These foreign-currency deposits are the financial assets of the central banks and monetary authorities that are held in different reserve currencies (e.g., the U.S. dollar, the euro, the pound sterling, the Japanese yen, the Indian rupee, the Swiss franc, and the Chinese renminbi) and which are used to back its liabilities (e.g., the local currency issued and the various bank reserves deposited with the Central bank by the government or financial institutions). Before the end of the gold standard, gold was the preferred reserve currency.

Foreign-exchange reserves is generally used to intervene in the foreign exchange market to stabilize or influence the value of a country's currency. Central banks can buy or sell foreign currency to influence exchange rates directly. For example, if a currency is depreciating, a central bank can sell its reserves in foreign currency to buy its own currency, creating demand and helping to stabilize its value. High levels of reserves instill confidence among investors and traders. If market participants believe that a country has sufficient reserves to support its currency, they are less likely to engage in speculative attacks that could lead to a sharp depreciation. In times of economic uncertainty or financial market volatility, central banks can use reserves to smooth out fluctuations in the exchange rate, reducing the impact of sudden capital outflows or shocks to the economy. Adequate reserves ensure that a country can meet its international payment obligations, which helps maintain a stable exchange rate by preventing panic in the foreign exchange market. Having substantial reserves allows central banks to implement monetary policies more effectively. They can afford to maintain interest rates or engage in other measures without the immediate fear of depleting reserves, which can influence market expectations positively.

In accounting, amortization is a method of obtaining the expenses incurred by an intangible asset arising from a decline in value as a result of use or the passage of time. Amortization is the acquisition cost minus the residual value of an asset, calculated in a systematic manner over an asset's useful economic life. Depreciation is a corresponding concept for tangible assets.

Methodologies for allocating amortization to each accounting period are generally the same as those for depreciation. However, many intangible assets such as goodwill or certain brands may be deemed to have an indefinite useful life and are therefore not subject to amortization (although goodwill is subjected to an impairment test every year).

Value added is a term in economics for calculating the difference between market value of a product or service, and the sum value of its constituents. It is relatively expressed by the supply-demand curve for specific units of sale. Value added is distinguished from the accounting term added value which measures only the financial profits earned upon transformational processes for specific items of sale that are available on the market.

In business, total value added is calculated by tabulating the unit value added (measured by summing unit profit — the difference between sale price and production cost, unit depreciation cost, and unit labor cost) per each unit sold. Thus, total value added is equivalent to revenue minus intermediate consumption. Value added is a higher portion of revenue for integrated companies (e.g. manufacturing companies) and a lower portion of revenue for less integrated companies (e.g. retail companies); total value added is very nearly approximated by compensation of employees, which represents a return to labor, plus earnings before taxes, representative of a return to capital.

In macroeconomics, investment "consists of the additions to the nation's capital stock of buildings, equipment, software, and inventories during a year" or, alternatively, investment spending — "spending on productive physical capital such as machinery and construction of buildings, and on changes to inventories — as part of total spending" on goods and services per year. "accounting"The types of investment include residential investment in housing that will provide a flow of housing services over an extended time, non-residential fixed investment in things such as new machinery or factories, human capital investment in workforce education, and inventory investment (the accumulation, intentional or unintentional, of goods inventories)In measures of national income and output, "gross investment" (represented by the variable I ) is a component of gross domestic product (GDP), given in the formula GDP = C + I + G + NX, where C is consumption, G is government spending, and NX is net exports, given by the difference between the exports and imports, X − M. Thus investment is everything that remains of total expenditure after consumption, government spending, and net exports are subtracted (i.e. I = GDP − C − G − NX ).

"Net investment" deducts depreciation from gross investment. Net fixed investment is the value of the net increase in the capital stock per year.

In national income accounting, net national income (NNI) is net national product (NNP) minus indirect taxes. Net national income encompasses the income of households, businesses, and the government. Net national income is defined as gross domestic product plus net receipts of wages, salaries and property income from abroad, minus the depreciation of fixed capital assets (dwellings, buildings, machinery, transport equipment and physical infrastructure) through wear and tear and obsolescence.

It can be expressed as
