Fair value

In accounting and in most schools of economic thought, fair value is a rational and unbiased estimate of the potential market price of a good, service, or asset. The derivation takes into account such objective factors as the costs associated with production or replacement, market conditions and matters of supply and demand. Subjective factors may also be considered such as the risk characteristics, the cost of and return on capital, and individually perceived utility.

Vs market price.
There are two schools of thought about the relation between the market price and fair value in any form of market, but especially with regard to tradable assets:
Vs market value.
The latest edition of International Valuation Standards (IVS 2017), clearly distinguishes between fair value (now referred to as "equitable value"), as defined in the IVS, and market value, as defined in the IVS:
Accounting.
In accounting, fair value is used as a certainty of the market value of an asset (or liability) for which a market price cannot be determined (usually because there is no established market for the asset). Under US GAAP (FAS 157), fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. This is used for assets whose carrying value is based on mark-to-market valuations; for assets carried at historical cost, the fair value of the asset is not used.
Fair value measurements (US markets).
The Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 157: Fair Value Measurements ("FAS 157") in September 2006 to provide guidance about how entities should determine fair value estimations for financial reporting purposes. FAS 157 broadly applies to financial and nonfinancial assets and liabilities measured at fair value under other authoritative accounting pronouncements. However, application to nonfinancial assets and liabilities was deferred until 2009. Absence of one single consistent framework for applying fair value measurements and developing a reliable estimate of a fair value in the absence of quoted prices has created inconsistencies and incomparability. The goal of this framework is to eliminate the inconsistencies between balance sheet (historical cost) numbers and income statement (fair value) numbers.
Subsequently, FAS 157 was subsumed into FASB Accounting Standards Codification (ASC) Topic 820 (Fair Value Measurement), which now defines fair value as "The price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date." This is sometimes referred to as "exit value". In the futures market, fair value is the equilibrium price for a futures contract. This is equal to the spot price after taking into account compounded interest (and dividends lost because the investor owns the futures contract rather than the physical stocks) over a certain period of time. On the other side of the balance sheet the fair value of a liability is the amount at which that liability could be incurred or settled in a current transaction.
Topic 820 emphasizes the use of market inputs in estimating the fair value for an asset or liability. Quoted prices, credit data, yield curve, etc. are examples of market inputs described by Topic 820. Quoted prices are the most accurate measurement of fair value; however, many times an active market does not exist so other methods have to be used to estimate the fair value on an asset or liability. Topic 820 emphasizes that assumptions used to estimate fair value should be from the perspective of an unrelated market participant. This necessitates identification of the market in which the asset or liability trades. If more than one market is available, Topic 820 requires the use of the "most advantageous market". Both the price and costs to do the transaction must be considered in determining which market is the most advantageous market.
The framework uses 3-level fair value hierarchy to reflect the level of judgment involved in estimating fair values. The hierarchy is broken down into three levels:
The FASB, after extensive discussions, has concluded that fair value is the most relevant measure for financial instruments. In its deliberations of Statement 133, the FASB revisited that issue and again renewed its commitment to eventually measuring all financial instruments at fair value.
FASB published a staff position brief on October 10, 2008, in order to clarify the provision in case of an illiquid market.
International standards (IFRS).
IFRS 13, "Fair Value Measurement", was adopted by the International Accounting Standards Board on May 12, 2011. IFRS 13 provides guidance for how to perform fair value measurement under IFRS and became effective on January 1, 2013.
The guidance is similar to the US GAAP guidance. It defines fair value as "the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). When measuring fair value, an entity uses the assumptions that market participants would use when pricing the asset or the liability under current market conditions, including assumptions about risk." As a result, IFRS 13 requires entities to consider the effects of credit risk when determining a fair value measurement, e.g. by calculating a credit valuation adjustment (CVA) or debit valuation adjustment (DVA) on their derivatives.
