New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). This update outlines a new comprehensive revenue recognition model that supersedes most current revenue recognition guidance and requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. The FASB has issued several updates and/or practical expedients to ASU 2014-09.

ASU 2014-09 provides two methods of adopting the standard: using either a full retrospective approach or modified retrospective approach. We expect to elect the modified retrospective approach of adopting the standard. We have conducted an assessment of how ASU 2014-09 is likely to affect us, identifying the Company’s revenue streams and performance obligations. Our contracts with customers currently may be for single performance obligations or for multiple performance obligations. Based on our assessment, we do not believe the new standard significantly changes our accounting policy for these types of performance obligations. We have also evaluated the impact the new standard will have on our existing policies, contracts, accounting processes, internal controls, reporting systems and disclosure processes. We have begun implementing improvements and or enhancements to our business processes to support the implementation of the standard. We currently have not identified an improvement or enhancement that we would conclude would be a significant change to our internal control environment.

In July 2015, the FASB issued ASU 2015-11, “Inventory – Simplifying the Measurement of Inventory.” This guidance changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value.

This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company adopted this standard effective May 1, 2017. The adoption of this standard did not have a significant impact on the Company’s consolidated financial position or results of operations. In March 2016, the FASB issued ASU 2016-9, “Stock Compensation – Improvements to Employee Share-Based Payment Accounting.” This guidance simplifies various aspects related to how share-based payments are accounted for and presented in the financial statements. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company adopted this standard prospectively effective May 1, 2017. Prior periods were not retrospectively adjusted. The adoption of this standard did not have a significant impact on the Company’s consolidated financial position or results of operations.
