The objective is to reduce both complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently.

Generally accepted accounting principles have required different measurement attributes for different assets and liabilities that can create artificial volatility in earnings. The standard aims to help to mitigate accounting-induced volatility by enabling companies to report related assets and liabilities at fair value, which would likely reduce the need for companies to comply with detailed rules for hedge accounting.

"Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities," also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities.

The standard requires companies to provide additional information that will help investors and other users of financial statements to more easily understand the effect of the company's choice to use fair value on its earnings. It also requires entities to display the fair value of those assets and liabilities for which the company has chosen to use fair value on the face of the balance sheet. The new statement does not eliminate disclosure requirements included in other accounting standards, including requirements for disclosures about fair value measurements included in FASB Statements No. 157, Fair Value Measurements, and No. 107, Disclosures about Fair Value of Financial Instruments.

This statement is effective as of the beginning of an entity's first fiscal year beginning after Nov. 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity makes that choice in the first 120 days of that fiscal year and also elects to apply the provisions of Statement 157.
