Recent Accounting Standards Not Yet Effective In May 2014 the Financial Accounting Standards Board (FASB) issued an accounting standards update related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services.
