Recent Accounting Pronouncements
 
In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard, which is currently effective for the first quarter of 2018, will replace most existing revenue recognition guidance required by U.S. generally accepted accounting principles. The adoption of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.
