8. Accounting pronouncements

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers." This ASU is intended to clarify the principles for recognizing revenue by removing inconsistencies in revenue requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. In April 2015, the FASB voted to defer the effective date of the new revenue recognition standard by one year. As a result, the provisions of this ASU are now effective for interim and annual periods beginning after December 15, 2017. We are currently evaluating the impact this ASU may have on our consolidated financial position, results of operations or cash flows.
